As shown in Figures 1 to 36, the cleaning system of the embodiment of the present case includes a dust collecting pile 2 and a cleaning robot 1.

In the technical solution provided by the embodiment of this case, the cleaning robot includes a robot body. The robot body can be approximately circular in shape, or can have other shapes, including but not limited to an approximately D-shape with a front and a rear circle.

The cleaning robot may also include a cleaning system, a perception system, a control system, a drive system, an energy system, and a human-computer interaction system. The various systems coordinate with each other so that the cleaning robot can move autonomously to achieve the cleaning function. The functional components constituting the above-mentioned systems in the cleaning robot can be integrated in the cleaning robot body. The cleaning robot body may include an upper cover, a chassis, and a middle frame disposed between the upper cover and the chassis. The middle frame can serve as a basic framework for arranging various functional components. The upper cover and the chassis cover the surface of the main body of the equipment, play a role in protecting the internal components, and can enhance the aesthetics of the cleaning robot.

The perception system is used by the cleaning robot to perceive the external environment such as terrain and the position of the cleaning robot itself, and can provide the control system of the cleaning robot with various position information and motion status information of the machine.

In the technical solution provided in the embodiment of this case, the sensing system may include a position determination device, which includes but is not limited to an infrared transmitting and receiving device, a camera, and a laser distance sensor (LDS). The position determination device may be arranged on the top or side of the cleaning robot. During the movement of the cleaning robot, the position determination device obtains the current position of the cleaning robot by determining the distance between the cleaning robot and surrounding obstacles.

The buffer is used to buffer the collision between the robot and surrounding objects during movement. A layer of soft rubber is provided on the surface of the buffer, and when the buffer is installed on the main body of the device, it is separated from the main body of the device by a predetermined distance, thereby ensuring that the main body of the device can have enough deceleration time when a collision occurs.

The cleaning robot can display a map of the robot's environment, the location of the cleaning robot, and status information of the cleaning robot to the user through the mobile client program.

The energy system is used to provide power for the functional components of each system, and mainly includes a rechargeable battery and a power supply circuit. The rechargeable battery can be a nickel-metal hydride battery or a lithium battery. When the power in the rechargeable battery is lower than the predetermined minimum power, it can be charged by connecting the charging electrode disposed on the side or bottom of the device body to the charging device.

In addition, the cleaning robot also includes a cleaning module, which is arranged on the robot body. The cleaning module removes debris from the surface to be cleaned by interfering with the surface to be cleaned.

The cleaning module includes a wet cleaning part and a dry cleaning part. The wet cleaning part can be a flat mop connected to the robot body.

The dry cleaning part can be a roller brush 112. Through the cooperation of the roller brush 112, the dust box, the fan, etc., the ground impurities are sucked into the dust box through the negative pressure generated by the fan, that is, the ground impurities enter the dust box through the garbage inlet of the robot body.

In addition, the cleaning robot also includes a lifting structure, which is connected to the cleaning module and is configured to enable the cleaning module to move up and down relative to the mobile platform. In actual use, the lifting structure can be connected to the dry cleaning part alone so that the dry cleaning part moves up and down relative to the mobile platform, or it can be connected to the wet cleaning part alone so that the wet cleaning part moves up and down relative to the mobile platform, and it can be connected to the cleaning module including the dry cleaning part and the wet cleaning part as a whole at the same time.

Furthermore, the lifting structure may be equipped with additional power equipment to enable the lifting structure to acquire the ability to be actively raised or lowered, thereby enabling the cleaning module to be actively raised or lowered relative to the mobile platform.

In the technical solution provided in the embodiment of the present case, the dust collecting pile includes a main body 10, a dust bucket 20 and a fan assembly 40.

As shown in FIGS. 2 to 7 , the main body 10 includes a dust inlet channel 11, and the dust inlet channel 11 has a dust inlet port 111, and the dust inlet port 111 is used to communicate with the dust box so that the dust in the dust box can enter the dust inlet channel 11 through the dust inlet port 111. In conjunction with FIGS. 6 to 16 , the dust bucket 20 is detachably disposed on the main body 10, and the dust inlet end 21 of the dust bucket 20 is connected to the dust inlet channel 11, so as to collect the dust entering from the dust inlet channel 11. The dust bucket 20 can be cylindrical and vertically disposed on the main body 10.

The dust bucket includes a dust bag or a cyclone separator, wherein the main body can be selectively equipped with a dust bucket including a dust bag or a dust bucket including a cyclone separator;

The fan assembly 40 is arranged on the main body 10, and the air inlet 41 of the fan assembly 40 is connected to the air flow outlet end 22 of the dust bucket 20. The fan assembly 40 generates negative pressure to ensure that the dust in the dust box can enter the dust inlet channel 11 through the dust inlet 111 and make the air flow flow. The dust in the dust box here includes the debris in the dust box. The axis of the fan assembly 40 and the dust bucket 20 are parallel and perpendicular to the horizontal plane, and the two are placed side by side on the main body 10. The wind that enters the air intake duct through the dust inlet 111 and then enters the dust bucket 20 is directly discharged from the air flow outlet end 22 after cyclonic separation. The air flow enters horizontally and flows out horizontally. The air path is simple and efficient, and it is not easy to cause dust blockage. Preferably, the lower surfaces of the dust bucket 20 and the fan assembly 40 are substantially on the same horizontal plane.

Specifically, when the cleaning robot completes cleaning, its own power is insufficient, or its dust box is full of garbage, the cleaning robot can move back to the dust pile to complete charging or unload the garbage in the dust box into the dust pile.

When the cleaning robot moves back to the dust pile, the cleaning robot continuously searches for the dust collecting device through the signal receiving device. The dust collecting pile includes a signal transmitting device. For example, the signal transmitting device continuously transmits communication signals within a certain angle range for the cleaning robot to capture. When the cleaning robot captures the communication signal, it will determine the position of the dust collecting pile and move to the dust collecting pile through the navigation function.

Furthermore, if the cleaning robot starts from the dust pile when starting cleaning, the location of the dust pile can be recorded on the map, so that in the process of returning to the dust pile, it will give priority to going to the dust pile location that has been recorded on the map, and determine the location of the dust pile based on the signal transmitting device of the dust pile, and move to the dust pile through the navigation function, so as to reduce the time of finding the dust pile and improve the efficiency of returning to the dust pile.

Optionally, a sealing ring may be provided on the outer side of the dust inlet 111, and a brush cover 113 may be provided on the outer side of the roller brush 112 of the robot, and the sealing ring corresponds to a portion of the robot body and a portion of the brush cover 113. When the cleaning robot moves to the main body 10, and the garbage inlet of the cleaning robot is connected to the dust inlet 111 of the dust inlet channel 11, at this time, the fan assembly 40 is operated, thereby forming a seal between the garbage inlet of the cleaning robot and the dust inlet 111 of the dust inlet channel 11, thereby sucking the dust in the dust box into the dust inlet channel 11.

The lifting structure can enable the roller brush 112 and the roller brush cover 113 of the cleaning robot to move in a nearly vertical direction, so as to better achieve sealing cooperation with the dust inlet 111 and the sealing ring.

After the cleaning robot moves to its position, the dust collecting pile in this embodiment can suck the dust in the dust box into the dust barrel 20 for collection through the operation of the fan assembly 40, and finally the air flow is discharged by the fan assembly 40, so as to recover the dust in the dust box of the cleaning robot into the dust barrel 20, and the entire dust cleaning process can be automated.

Preferably, the roller brush 112 of the robot can cooperate with the operation of the fan assembly 40 to rotate in the opposite direction to the cleaning direction, thereby helping the fan assembly 40 to better discharge the dust in the dust box.

It should be noted that the dust bucket 20 is detachably arranged on the main body 10, so as to facilitate the cleaning and replacement of the dust bucket 20.

In one embodiment, as shown in Figures 15 to 17, the dust bucket 20 includes a cyclone separator 24. It should be noted that the cyclone separator 24 can be a cyclone separator known in the relevant technology. The working principle of the cyclone separator is to rely on the rotational motion caused by the tangential introduction of the airflow. When the particles rotate at high speed in the airflow, the centrifugal force is much greater than the gravity, and the greater the speed, the greater the centrifugal sedimentation velocity obtained by the particles. When the solid particles enter the conical cylinder from the tangential direction with the gas and rotate in the cylinder, the airflow collides with the wall of the device, and the particles hit the tube wall and rotate and fall, thereby achieving the purpose of separating the solid and the gas. In this embodiment, the gas finally enters the air inlet end 31 of the first filter assembly 30 through the air outlet end 22 of the dust bucket 20.

The cyclone separator 24 includes a first-stage separation cyclone 241 and a second-stage separation cyclone 242, and the axis of the first-stage separation cyclone 241 is approximately parallel to the axis of the second-stage separation cyclone 242. After the axis of the first-stage separation cyclone 241 is approximately parallel to the axis of the second-stage separation cyclone 242, the complexity of the air path in the dust bin can be greatly reduced, thereby reducing the risk of dust accumulation when the dust collected in the dust bin increases, and enhancing the overall dust collection effect of the cyclone separator.

Furthermore, the axes of the first-stage separation cyclone 241 and the second-stage separation cyclone 242 can completely overlap, so that the wind path in the dust bucket is more unobstructed.

The secondary separation cyclone 242 may include a plurality of cyclone separators, the main body of which is a cone with a large upper end and a small lower end, and is respectively distributed around the axis of the secondary separation cyclone 242. The provision of multiple sets of cyclone separators improves the dust separation efficiency of the secondary separation cyclone and further enhances the dust collection capacity of the dust collecting pile. The number of secondary cyclone separators may be nine, twelve, or fifteen, and the more the number, the higher the separation efficiency.

The outer periphery of the secondary separation cyclone 242 is a separation filter 243. The outer surface of the primary separation cyclone 241, the inner surface of the dust barrel 20 and the outer surface of the separation filter 243 together form a primary cyclone. The air separated by the primary cyclone has separated the larger particle garbage from the airflow and falls into the outer side of the primary separation cyclone 241. The separation filter 243 is used to pass the airflow that enters the secondary separation cyclone 242 after the primary cyclone separation. The separation filter 243 preferably uses a metal filter to increase the service life and improve the filtering effect. The separation filter 243 is an annular net, and the support frame of the first-stage separation cyclone 241 is used to set up the bottom of the separation filter 243. The granular garbage filtered by the separation filter 243 is gathered below the support frame of the first-stage separation cyclone 241, and the outer edge of the support frame of the first-stage separation cyclone 241 can extend downward to form a skirt shape to prevent the granular garbage separated by the first-stage cyclone from moving upward.

The secondary separation cyclone 242 also includes a sealing end cap 246. The sealing end cap 246 is an annular plate, which is rotated around the axis of the sealing end cap 246 and is used to seal the airflow passing through the separation filter 243. The separation filter 243, the inner wall of the primary separation cyclone 241 and the sealing end cap 246 form a sealed space to achieve a secondary cyclone that seals the airflow passing through the separation filter 243. Each secondary separation cyclone 242 forms a cyclone for gas-solid separation, and the separated solid particle garbage falls into the inner side of the primary separation cyclone 241. According to actual conditions, the sealing end cap 246 and the bottom of the separation filter 243 may not be on the same horizontal plane.

In one embodiment, a positioning buckle device is provided between the secondary separation cyclone 242 and the separation filter 243, and the buckle device includes a positioning block 244 and a positioning slot 245. The positioning block 244 and the separation filter 243 can be respectively arranged on the secondary separation cyclone 242 and the separation filter 243 to achieve the limited cooperation of the secondary separation cyclone 242 and the separation filter 243. The design of the buckle device ensures that after the user disassembles and cleans the secondary separation cyclone 242 and the separation filter 243 of the dust bin, the user can simply and conveniently reinstall the secondary separation cyclone 242 and the separation filter 243, respectively, without causing loose sealing due to loose buckles or improper installation.

Preferably, a positioning block 247 is provided on the sealing end cover 246, and the positioning block 247 cooperates with the snap-fit device, which can also ensure that the user can simply and conveniently reinstall the sealing end cover 246 after removing and cleaning the sealing end cover 246, without causing a loose seal due to a loose snap-fit or improper installation.

In one embodiment, as shown in Figures 5 and 7, the body 10 includes a base 101 and a mounting body 102. A dust inlet channel 11 is formed in the base 101, and a dust inlet port 111 is disposed at the top of the base 101. The cleaning robot moves to the base 101 to clean dust.

The mounting body 102 is connected to the base 101 , and an air intake duct 80 is disposed in the mounting body 102 . As shown in FIG. 8 , the air intake duct 80 connects the dust inlet passage 11 and the dust inlet end 21 , so that dust enters the dust barrel 20 from the dust inlet passage 11 through the air intake duct 80 .

Optionally, the dust bucket 20 is detachably mounted on the mounting body 102. The fan assembly 40 is mounted on the mounting body 102.

The cleaning robot enters the base 101 from the front end of the base 101, and the mounting body 102 is arranged at the rear end of the base 101, so that the cleaning robot will not collide with the mounting body 102 during the movement process.

In some embodiments, the mounting body 102 and the base 101 may be an integrated structure, where the integrated structure may be formed in one piece, or may be formed by connecting and fixing two independent components to form an integral structure.

In some embodiments, the mounting body 102 is detachably connected to the base 101, that is, the mounting body 102 can be separated from the base 101 before use to facilitate transportation and storage, etc. When in use, the mounting body 102 is connected to the base 101 by fasteners or card connection or other related connection methods.

Optionally, the air intake duct 80 may be connected to the base 101, that is, after the mounting body 102 is separated from the base 101, the air intake duct 80 is connected to the base 101. Alternatively, the air intake duct 80 may be connected to the mounting body 102, that is, after the mounting body 102 is separated from the base 101, the air intake duct 80 is connected to the mounting body 102. Alternatively, the air intake duct 80 may be separated from the base 101 and the mounting body 102. In some embodiments, it is not excluded that the air intake duct 80 is integrated into the base 101 or the mounting body 102.

In one embodiment, as shown in FIG10 and FIG11 , the dust collecting pile further includes a first filter assembly 30. The first filter assembly 30 is disposed above the fan assembly 40.

The air inlet end 31 of the first filter assembly 30 is connected to the air outlet end 22 of the dust container 20 to filter the air discharged from the dust container 20 .

The air outlet 32 of the first filter assembly 30 is connected to the air inlet 41 of the fan assembly 40 . When the cleaning robot moves to the main body 10, and the garbage inlet of the cleaning robot is connected to the dust inlet 111 of the dust inlet channel 11, the fan assembly 40 generates negative pressure during operation, and can suck the dust in the dust box into the dust barrel 20 for collection, and filter the dust through the first filter assembly 30 before the airflow enters the fan assembly 40, thereby preventing the dust from entering the fan assembly 40. Finally, the airflow is discharged by the fan assembly 40, thereby realizing the recovery of the dust in the dust box of the cleaning robot into the dust barrel 20, and the entire dust cleaning process can be automated.

The first filter assembly 30 is located above the fan assembly 40, that is, the airflow discharged from the dust bucket 20 needs to be filtered through the first filter assembly 30 first, and then flows into the air inlet 41 of the fan assembly 40 from the bottom of the first filter assembly 30, so that the flow path distribution of the airflow is more reasonable, and it can ensure that the distribution of components is more reasonable and the height space is effectively utilized.

The first filter assembly 30 may be directly disposed on the main body 10 , or the first filter assembly 30 may be directly disposed on the fan assembly 40 .

In some embodiments, the first filter assembly 30 is disposed on the mounting body 102 , that is, after the mounting body 102 is separated from the base 101 , the dust bucket 20 , the first filter assembly 30 , and the fan assembly 40 can be separated from the mounting body 102 and the base 101 .

Optionally, the first filter assembly 30 can be detachably disposed on the mounting body 102 , or the first filter assembly 30 can also be fixed on the mounting body 102 .

In one embodiment, as shown in FIG12 , the main body 10 further includes: a first mounting portion 13 and a second mounting portion 14. The first mounting portion 13 and the second mounting portion 14 are used to mount the dust bucket 20 and the first filter assembly 30, respectively. The first mounting portion 13 and the second mounting portion 14 are disposed on the mounting main body 102.

A first detection component is disposed between the dust bucket 20 and the first mounting portion 13, and the first detection component is used to detect whether the dust bucket 20 and the first mounting portion 13 are properly installed. For example, when the dust bucket 20 and the first mounting portion 13 are properly installed, the first detection component can send a first signal.

A second detector is disposed between the first filter assembly 30 and the second mounting portion 14, and is used to detect whether the first filter assembly 30 and the second mounting portion 14 are properly installed. For example, when the first filter assembly 30 and the second mounting portion 14 are properly installed, the second detector can send a second signal.

The dust collecting pile further includes a control unit, which is connected to the first detector or the second detector by signal, and is connected to the fan assembly 40 by signal, and the first detector is connected to the second detector by signal, so that when at least one of the dust bucket 20 and the first filter assembly 30 is not installed in place, the control unit cannot start the fan assembly 40, that is, the first detector and the second detector are in a series relationship, so the control unit can only start the fan assembly 40 when the first detector sends a first signal and the second detector sends a second signal. For example, the first detector can be connected to the control end of the second detector, and the signal transmitting end of the second detector is connected to the control unit. If the control end of the second detector cannot receive the first signal sent by the first detector, even if the first filter assembly 30 and the second mounting portion 14 are installed in place, the second detector cannot send a start signal (such as the second signal) to the control unit.

In this embodiment, by connecting the first detection component and the second detection component in series, the relationship between the dust bucket 20 in-place detection and the first filter assembly 30 in-place detection can be realized, that is, if the dust bucket 20 is not in place or the first filter assembly 30 is not in place or both are not in place, the control unit can identify them as not in place (that is, the control unit determines that the dust pile is not installed in place), thereby reducing electrical connection components and identification components.

In one embodiment, the dust bucket 20 is detachably connected to the first mounting portion 13, so as to facilitate cleaning and replacement of the dust bucket 20.

That is, the external structure of the dust bucket 20 can be a universal structure, the structure connected to the first mounting portion 13 adopts a unified structure, and the inside thereof can be a dust bag or a cyclone separator, so that the first mounting portion 13 can be selectively equipped with a dust bucket 20 including a dust bag or a dust bucket 20 including a cyclone separator.

In one embodiment, the first mounting portion 13 and the second mounting portion 14 are spaced apart so that the dust bucket 20 or the first filter assembly 30 can be installed on the main body 10 first, or the dust bucket 20 and the first filter assembly 30 can be installed on the main body 10 at the same time, that is, the installation of the dust bucket 20 and the first filter assembly 30 is not limited by the installation sequence, and can be installed and disassembled at will according to needs without interference between components, thereby simplifying the structure and facilitating installation.

The first mounting portion 13 and the second mounting portion 14 can be sequentially distributed on both sides of the base 101 , and after the dust bucket 20 is mounted on the first mounting portion 13 , two structures with similar structural appearances are formed above the base 101 , and the first filter assembly 30 is mounted inside the second mounting portion 14 .

A non-contact sensing element is disposed on the second mounting portion 14, and a non-contact sensing matching element is disposed on the first filter assembly 30. The non-contact sensing matching element can be matched with the non-contact sensing element when the first filter assembly 30 is mounted to the second mounting portion 14, so that the non-contact sensing matching element can sense the non-contact sensing element.

It should be noted that the contact detection element can be a contact sensor in the relevant technology, such as a pressure sensor, a switch element, etc., and the non-contact detection element can be a non-contact sensor in the relevant technology, such as a laser sensor, an inductive proximity sensor, etc.

In some embodiments, as shown in Figures 19 and 20, the contact detection element includes: a switch 131, the switch 131 is arranged on the first mounting portion 13; a detection button 132, the detection button 132 is arranged opposite to the switch 131, so that when the dust bucket 20 and the first mounting portion 13 are installed in place, the detection button 132 presses the switch 131 to be in a closed state, that is, after the dust bucket 20 is installed in place, the switch 131 is in a closed state to output a corresponding signal.

The switch 131 can be a conventional button connected to the line. Only when the detection button 132 is pressed in place, the button can be turned on to achieve the conduction of the line and thus realize signal transmission.

Optionally, the contact detection element further includes: an elastic member 133, the elastic member 133 is arranged on the first mounting portion 13, and the detection button 132 is penetrated in the elastic member 133; wherein the elastic member 133 is located between the detection button 132 and the first mounting portion 13, so that when the dust bucket 20 is separated from the first mounting portion 13, the elastic member 133 drives the detection button 132 to release the switch 131, so that the switch 131 is in an open state. The detection button 132 can be arranged on the first mounting portion 13, and it moves downward by the pressure of the dust bucket 20. When the dust bucket 20 moves upward away from the first mounting portion 13, the detection button 132 can move upward driven by the elastic member 133 to release the switch 131. The bottom end of the detection button 132 has a limiting structure to prevent the detection button 132 from being separated from the first mounting portion 13.

In some embodiments, the switch 131 is disposed on the second mounting portion 14, and the detection button 132 is disposed opposite to the switch 131, so that when the first filter assembly 30 and the second mounting portion 14 are installed in place, the detection button 132 presses the switch 131 to be in a closed state, that is, after the first filter assembly 30 is installed in place, the switch 131 is in a closed state to output a corresponding signal.

In one embodiment, as shown in Figures 21 and 22, the first filter assembly 30 includes: a top cover 35, the top cover 35 has an air inlet channel 351, the air inlet channel 351 connects the air inlet end 31 and the connecting pipe 17; a filter portion 34, the filter portion 34 is arranged on the top cover 35, and is arranged opposite to the air outlet end 32, so that dust is filtered through the filter portion 34 to prevent dust from entering the fan assembly 40.

Optionally, the filter portion 34 may be a filter structure in the related art, such as a filter mesh structure. The specific structural form may be, for example, a circular mesh structure, thereby achieving dust filtering.

Optionally, as shown in FIG. 22 , the filter portion 34 is a bagged structure, that is, the filtering area of the filter portion 34 is increased, and the filtering contact area is increased, thereby improving the filtering effect. Due to the increase in the filtering area, the service life of the filter portion 34 will be greatly increased, thereby reducing the replacement frequency of the filter portion 34.

It should be noted that the bag structure can be connected so that the filter part 34 has a containing space, and the airflow enters the containing space and is then discharged from the filter part 34.

As shown in FIG. 22 , the first filter assembly 30 further includes: a dust container 33, the dust container 33 having an air inlet end 31 and an air outlet end 32, and the dust container 33 is disposed in the filter portion 34, and the filter portion 34 is disposed opposite to the air outlet end 32, so that the airflow discharged through the air outlet end 32 passes through the filter portion 34 and then enters the air inlet 41 of the fan assembly 40. The dust container 33 can absorb dust in the airflow, that is, it realizes the primary absorption of dust in the airflow, and prevents a large amount of dust from entering the filter portion 34 and clogging the filter portion 34.

In one embodiment, the dust container 33 includes dust cotton. After entering the first filter assembly 30, the airflow will first pass through the dust cotton. The dust cotton cannot intercept all dust within the specification, but can intercept a portion of larger particles, reducing the risk of the filter part 34 being blocked, thereby improving the service life of the entire first filter assembly 30.

Optionally, the dust container 33 includes a sponge. The filter portion 34 can be a filter mesh, and the filter mesh can include filter cotton.

In one embodiment, as shown in FIG. 22 , the air inlet end 31 and the air outlet end 32 are both located on the outer surface of the dust container 33, and the area of the air inlet end 31 is smaller than the area of the air outlet end 32, so that the airflow can enter the dust container 33 from a relatively small surface, thereby increasing the path length of the airflow through the dust container 33, thereby increasing the amount of dust absorbed and further reducing the impact of dust on the filter portion 34.

In one embodiment, the filter portion 34 wraps the dust container 33. The filter portion 34 can not only fix the dust container 33, but also allow the airflow flowing out of the dust container 33 to be discharged directly through the filter portion 34, thereby ensuring the filtering effect and simplifying the structure.

In one embodiment, the dust container 33 and the filter 34 are disposed on the top cover 35 , so that the dust container 33 and the filter 34 are fixed on the top cover 35 .

Specifically, the top cover 35 of the first filter assembly 30 can be connected to the main body 10, so that the first filter assembly 30 is disposed on the main body 10.

Optionally, at least one of the dust container 33 and the filter portion 34 can be directly fixed to the top cover 35, that is, the dust container 33 can be connected to the top cover 35, and the filter portion 34 can be wrapped on the dust container 33, that is, the filter portion 34 is connected to the dust container 33, and the filter portion 34 may not be directly connected to the top cover 35.

Optionally, the filter portion 34 is connected to the top cover 35 to form a receiving space between the filter portion 34 and the top cover 35, and the dust container 33 is located in the receiving space, that is, the dust container 33 is fixed in the receiving space formed between the filter portion 34 and the top cover 35.

In one embodiment, the filter 34 is detachably disposed on the top cover 35, so as to facilitate the replacement of the filter 34 and the dust container 33. The filter 34 and the top cover 35 can be connected by snapping, bonding or by fasteners, which is not limited here, as long as it is convenient for disassembly and assembly.

In one embodiment, the area of the dust container 33 covered by the top cover 35 is smaller than the area of the dust container 33 covered by the filter portion 34, that is, the air inlet end 31 of the dust container 33 is smaller than the air outlet end 32, ensuring that the airflow flows out quickly and the dust container 33 absorbs dust to the greatest extent.

In one embodiment, as shown in FIG. 23 and FIG. 24 , the fan assembly 40 includes: a housing 43 , a fan 44 and a flexible member 45 .

The housing 43 is arranged on the main body 10, and the flexible member 45 is located between the housing 43 and the fan 44. The fan 44 is fixed in the housing 43 through the flexible member 45, and the flexible member 45 prevents the fan 44 from directly contacting the housing 43. The arrangement of the flexible member 45 can prevent the fan 44 from directly contacting the housing 43, thereby preventing a loud noise, and because the fan 44 is fixed in the housing 43 through the flexible member 45, the housing 43 can be adapted to different types of fans 44 by simply replacing the flexible member 45, thereby improving the versatility of the housing 43.

Specifically, the main body 10 forms a mounting cavity, and the fan assembly 40 and the first filter assembly 30 are both arranged in the mounting cavity, and a partition is provided between the fan assembly 40 and the first filter assembly 30, and a second channel 18 is provided on the partition, and the second channel 18 is connected to the air outlet 32 of the first filter assembly 30 and the air inlet 41 of the fan assembly 40, so as to ensure that the airflow discharged through the first filter assembly 30 only enters the air inlet 41 of the fan assembly 40 through the second channel 18, as shown in Figures 11 and 12. The main body 10 realizes the protection of the fan assembly 40 and the first filter assembly 30, and prevents the fan assembly 40 and the first filter assembly 30 from being exposed to the external environment.

In one embodiment, as shown in Figures 23 and 24, the shell 43 includes: a first shell member 431; a second shell member 432, and the second shell member 432 is detachably connected to the first shell member 431 to release or fix the fan 44 and the flexible member 45, which not only facilitates the installation of the fan 44 and the flexible member 45, but also allows subsequent maintenance and replacement, and different types of fans 44 can be selected to replace the original type of fan 44, and only the flexible member 45 needs to be adaptively replaced, thereby realizing the universality of the shell 43.

In some embodiments, the second shell member 432 is sealedly connected to the first shell member 431, and the second shell member 432 and the first shell member 431 can be connected by a plurality of fasteners.

In one embodiment, as shown in Figure 24, the flexible member 45 includes: a first flexible portion 451, the first flexible portion 451 is arranged between the fan 44 and the first shell member 431 to support the fan 44; a second flexible portion 452, at least a portion of the second flexible portion 452 is arranged between the fan 44 and the second shell member 432 to clamp the fan 44 with the first flexible portion 451. The second flexible portion 452 can be filled between the fan 44 and the second shell part 432 to prevent the fan 44 from moving relative to the second shell part 432 and ensure that the fan 44 is fixed in the second shell part 432, and the first flexible portion 451 can be filled between the fan 44 and the first shell part 431 to prevent the fan 44 from moving relative to the first shell part 431 and ensure that the fan 44 is fixed in the first shell part 431. The first flexible portion 451 and the second flexible portion 452 fix the fan 44 and completely avoid hard contact between the fan 44 and the shell 43.

Optionally, the first flexible portion 451 and the second flexible portion 452 may be connected.

Optionally, the first flexible portion 451 and the second flexible portion 452 are independently arranged, that is, during the specific installation, the first flexible portion 451 and the fan 44 can be first arranged in the first shell member 431, and then the second flexible portion 452 and the second shell member 432 are snapped onto the fan 44 and the first shell member 431, and the second shell member 432 is fixed to the first shell member 431, thereby completing the installation of the fan assembly 40.

In one embodiment, part of the second flexible portion 452 is clamped between the first shell member 431 and the second shell member 432 to seal the gap between the first shell member 431 and the second shell member 432, thereby avoiding the use of other seals to seal the first shell member 431 and the second shell member 432. The structure is simpler and the installation steps can be reduced.

In one embodiment, the first flexible portion 451 is a rubber pad, and the second flexible portion 452 is a rubber sleeve. The rubber pad is supported between the fan 44 and the first housing member 431, and the rubber sleeve is sleeved on the upper part of the fan 44 to protect the fan 44.

In one embodiment, the second housing member 432 is provided with an air flow hole 433, which is connected to the air inlet 41 of the fan 44, and there is a gap between the first housing member 431 and the fan 44; wherein an exhaust passage 46 is formed between the first flexible portion 451, the second flexible portion 452, the first housing member 431 and the fan 44, and the exhaust passage 46 is connected to the air outlet 42 of the fan 44. The airflow discharged from the first filter assembly 30 enters the air inlet 41 of the fan 44 through the air flow hole 433, and is discharged into the exhaust passage 46 through the air outlet 42 of the fan 44, and is finally discharged from the exhaust passage 46, thereby realizing the circulation of the airflow.

As shown in FIG. 25 , the first housing member 431 has a space 4311 for accommodating the fan 44, and a plurality of air holes 4312 are provided on the side wall of the space 4311, that is, the airflow in the exhaust passage 46 is discharged through the air holes 4312, and the air holes 4312 occupy the circumferential direction of the first housing member 431, so that the airflow can circulate in the exhaust passage 46. The first housing member 431 has housing members that are sleeved on the inner and outer sides, and the airflow space formed between the housing members that are sleeved on the inner and outer sides is connected to the exhaust passage 46 through the air holes 4312, and finally discharged from the fan assembly 40.

In one embodiment, the fan assembly 40 further includes an exhaust hole 434 , which is connected to the exhaust channel 46 , so as to exhaust the air flow in the exhaust channel 46 out of the fan assembly 40 .

Optionally, the exhaust hole 434 is provided on the shell 43 to discharge the airflow in the exhaust channel 46. Specifically, the exhaust hole 434 can be provided on the first shell member 431, that is, the airflow in the exhaust channel 46 can be discharged from the fan assembly 40 without opening a hole in the second flexible portion 452. The exhaust hole 434 can also be provided on the second shell member 432, that is, a hole can be opened on the second flexible portion 452 so that the exhaust hole 434 is connected to the exhaust channel 46. There is no limitation on the specific position of the exhaust hole 434, as long as the airflow can be discharged from the exhaust channel 46.

In one embodiment, as shown in FIG. 23 , the fan assembly 40 further includes a muffler 47, which is disposed on the housing 43, and the inlet of the muffler 47 is connected to the exhaust hole 434, or the outlet of the muffler 47 is connected to the exhaust hole 434. That is, the airflow discharged from the exhaust passage 46 passes through the muffler 47 for silencing, thereby reducing the noise brought by the airflow.

Optionally, the muffler 47 can be disposed inside the shell 43, and the exhaust passage 46 is connected to the inlet of the muffler 47, and the outlet of the muffler 47 can be connected to the exhaust hole 434, so that the air flow passes through the muffler 47 before being discharged from the shell 43.

Optionally, the muffler 47 can be arranged outside the shell 43, and the exhaust channel 46 is connected to the exhaust hole 434, and the exhaust hole 434 is connected to the inlet of the muffler 47, so that the air flow is first discharged from the shell 43 and then silenced by the muffler 47.

In one embodiment, the exhaust passage 46 is arranged around the circumferential outer surface of the fan 44, and the length of the exhaust passage 46 extending along the circumferential outer surface of the fan 44 is greater than the length of the exhaust hole 434 extending along the circumferential outer surface of the fan 44, that is, the airflow exhausted by the fan 44 is only discharged to the outside of the shell 43 through a relatively fixed position, so that the airflow can rotate nearly one circle in the exhaust passage 46 and then be discharged from the exhaust hole 434, so that the noise can be reduced by extending the airflow path.

Specifically, the circumferential outer surface of the fan 44 can form nearly a circle of air outlets 42, and the exhaust channel 46 also forms nearly a circle of surrounding space, so that the airflow of the air outlet 42 at each position can be directly discharged into the exhaust channel 46. At this time, the exhaust holes 434 on the shell 43 can be located in the circumferential direction of the shell 43, or the exhaust holes 434 on the shell 43 can be set at the top of the shell 43. At this time, the exhaust channel 46 can be connected to the exhaust holes 434 through a pipeline, so as to ensure that the airflow discharged from the exhaust channel 46 needs to be rotated to a relatively fixed position for discharge, thereby reducing noise by increasing the airflow path.

In one embodiment, as shown in FIG. 10 and FIG. 11 , a wind pressure measuring hole 48 is provided on the main body 10 , a wind pressure pipe 49 is connected to the wind pressure measuring hole 48 , and the end of the wind pressure pipe 49 is connected to a wind pressure detection device.

Since the wind pressure detection device needs electrical connection, in order to reduce the impact of the air pressure change in the main body 10 on the life of the electrical connection device, the wind pressure detection device is installed outside the wind duct of the entire dust collecting pile. Therefore, it is necessary to connect the wind duct with the wind pressure detection device through the wind pressure measuring hole 48 and the wind pressure pipeline 49, so that the wind pressure detection device can detect the wind pressure in the wind duct.

The wind pressure detection device can be installed on the circuit board of the dust collecting pile, thereby realizing the integration of electronic equipment and facilitating product production.

Preferably, the wind pressure measuring hole 48 is disposed between the fan assembly 40 and the first filter assembly 30. After the fan 44 is started, the fan 44 will first draw out the air in the first filter assembly 30 to form a local negative pressure, and then the air pressure will form an airflow to complete the entire air extraction action. Therefore, the wind pressure measuring hole 48 is disposed between the fan assembly 40 and the first filter assembly 30 to achieve the highest measurement accuracy and measurement efficiency.

Preferably, since the first filter assembly 30 is a cylindrical structure and may directly contact the wind pressure measuring hole 48 during installation, a terrace-shaped protrusion may be provided on the outer side of the air inlet of the fan assembly 40, and the wind pressure measuring hole 48 may be provided at the terrace-shaped protrusion to prevent the wind pressure measuring hole 48 from being blocked by the first filter assembly 30 and affecting the measurement effect.

In one embodiment, as shown in FIGS. 8 to 11 , the dust collecting pile further includes: a second filter assembly 50, the second filter assembly 50 is arranged around the first filter assembly 30, and the air collecting port 51 of the second filter assembly 50 is connected to the air outlet 42 of the fan assembly 40, that is, the airflow discharged from the air outlet 42 of the fan assembly 40 needs to be filtered by the second filter assembly 50 before being discharged, thereby ensuring that the discharged airflow is clean.

In some embodiments, the second filter assembly 50 may be a conventional filter structure, that is, it may include a filter mesh, so as to achieve secondary filtration of the airflow and ensure that the discharged airflow is clean. For example, the second filter assembly 50 may be an annular structure, that is, a circumferentially closed structure, which is arranged around the first filter assembly 30. The airflow enters the fan assembly 40 from the first filter assembly 30 and flows from top to bottom, and then the airflow enters the second filter assembly 50 from the fan assembly 40 and flows from bottom to top.

In some embodiments, as shown in FIG. 26 , the second filter assembly 50 is provided with an opening 53 , that is, the second filter assembly 50 may be a circumferentially non-closed structure.

The corresponding space in the opening 53 is used to form a space for providing the communication pipe 17 and the intake duct 80.

In some embodiments, as shown in Figures 28 to 30, the second filter assembly 50 includes a frame 54 and a filter 55, the filter 55 is disposed on the frame 54, the filter 55 is formed with an avoidance groove 56, the avoidance groove 56 includes a first opening 561, a second opening 562 and a third opening 563, the first opening 561 and the second opening 562 are arranged opposite to each other, and both ends of the third opening 563 pass through the first opening 561 and the second opening 562. The frame 54 serves as a supporting structure of the second filter assembly 50 to ensure the stability of the second filter assembly 50. The frame 54 is disposed on the main body 10, and the avoidance groove 56 is formed to accommodate the second mounting portion 14 accommodating the first filter assembly 30, so that the airflow discharged by the fan assembly 40 enters between the second filter assembly 50 and the second mounting portion 14.

It should be noted that the avoidance groove 56 includes a first opening 561, a second opening 562 and a third opening 563. The first opening 561 and the second opening 562 are arranged opposite to each other, and both ends of the third opening 563 pass through the first opening 561 and the second opening 562, that is, the frame 54 is adapted to the filter 55, so that an opening 53 is formed on the second filter assembly 50. The overall structure of the second filter assembly 50 can be similar to a C-shaped structure, or can be a U-shaped structure, which is not limited here, and can be determined according to the specific structural form of the second mounting portion 14, so as to ensure the reasonable distribution of components.

The second filter assembly 50 in this embodiment includes a frame 54 and a filter 55, and the filter 55 is formed with an avoidance groove 56, so that the second filter assembly 50 can be used to avoid other internal structures, which can not only reduce the size of the filter 55, but also ensure the reasonable arrangement of other components, thereby improving the performance of the second filter assembly 50.

In one embodiment, the filter 55 is an arc-shaped filter, that is, under the premise of ensuring the effective filtering area, the structure of the filter 55 can be minimized to adapt to the circumferential outer surface of the second mounting portion 14.

In one embodiment, the area of the third opening 563 is smaller than the area of the filter 55, which ensures that the filter 55 has a sufficient filtering area.

In one embodiment, the filter 55 comprises sealing foam.

In one embodiment, as shown in FIG31 and FIG32 , the body 10 further includes a liquid outlet 12 , which is disposed on the base 101 , and one end of the liquid outlet 12 is connected to the dust inlet channel 11 . Furthermore, the liquid outlet 12 is located at the bottom of the body 10 .

As shown in Figures 31 and 32, the dust collecting pile further includes: a shielding member 90, which can be movably arranged on the main body 10 so that the shielding member 90 has a sealing position for shielding the liquid outlet 12 and an open position for releasing the liquid outlet 12; wherein, when the dust in the dust box enters the dust inlet channel 11, the shielding member 90 is located in the sealing position, and when the dust in the dust box stops entering the dust inlet channel 11, the shielding member 90 can be moved to the open position so that the dust inlet channel 11 is connected to the outside through the liquid outlet 12.

When the dust in the dust box enters the dust inlet channel 11, it is necessary to ensure that the dust inlet channel 11 forms a negative pressure environment, so the shielding member 90 closes the liquid outlet 12 to ensure that the dust inlet channel 11 is not connected to the outside. When the dust in the dust box stops entering the dust inlet channel 11, the shielding member 90 can be opened to connect the dust inlet channel 11 to the outside, and the liquid entering the dust inlet channel 11 can be discharged from the dust inlet channel 11 through the liquid outlet 12, thereby ensuring that the dust inlet channel 11 is dry to the greatest extent.

It should be noted that the above-mentioned outside world can be connected to the external environment space, or it can be other spaces independent of the dust inlet channel 11. For example, a liquid collector can be provided to allow the liquid in the dust inlet channel 11 to flow into the liquid collector. At this time, the space formed by the liquid collector can also be understood as the outside world.

In some embodiments, the shielding member 90 may be movably disposed on the body 10, and the shielding member 90 may be driven to move by a driving mechanism, thereby closing and releasing the liquid outlet 12. Specifically, the driving mechanism may be a pneumatic cylinder, an oil cylinder, or an electric cylinder, and the telescopic rod of the driving mechanism may drive the shielding member 90 to move relative to the liquid outlet 12, thereby closing and releasing the liquid outlet 12. Alternatively, the driving mechanism may include a motor, and the shielding member 90 may be driven by the motor to rotate relative to the body 10, thereby closing and releasing the liquid outlet 12.

It should be noted that when the fan assembly 40 is running, the dust in the dust box starts to be cleaned, and the shielding member 90 can be rotated from the open position to the sealed position. Specifically, the control unit of the dust collecting pile can control the above-mentioned driving mechanism to drive the shielding member 90 from the open position to the sealed position before controlling the operation of the fan assembly 40, or the control unit can control the operation of the fan assembly 40 and the above-mentioned driving mechanism at the same time. When the fan assembly 40 stops running, the dust in the dust box stops being cleaned, and the shielding member 90 can be rotated from the sealed position to the open position. Specifically, the control unit of the dust collecting pile can control the above-mentioned driving mechanism to drive the shielding member 90 from the sealing position to the open position after controlling the fan assembly 40 to stop running, or the control unit can control the above-mentioned driving mechanism to operate while controlling the fan assembly 40 to stop running.

In some embodiments, the shielding member 90 can be connected to the body 10, and the movement of the shielding member 90 does not rely on a driving mechanism. The shielding member 90 can be driven by the fan assembly 40 to rotate from the open position to the sealed position, that is, when the fan assembly 40 is running, the shielding member 90 can be driven by the negative pressure generated by the fan assembly 40 to move from the open position to the sealed position. When the fan assembly 40 stops running, the shielding member 90 can rotate from the sealed position to the open position under the action of gravity.

Optionally, the shielding member 90 may be disposed on a plate, and the plate may be rotatably disposed on the main body 10, thereby ensuring that the shielding member 90 is rotated from the sealing position to the opening position under the action of gravity.

In one embodiment, the liquid outlet 12 is connected to the side of the dust inlet channel 11 close to the dust barrel 20, that is, when the fan assembly 40 is running, the liquid will flow from the dust inlet port 111 along the dust inlet channel 11 to the dust barrel 20. Therefore, after the fan assembly 40 stops running, most of the liquid is concentrated on the side close to the dust barrel 20. At this time, opening the liquid outlet 12 can easily allow the liquid to flow out of the liquid outlet 12.

In one embodiment, as shown in FIG. 32 , a sealing groove 19 is provided on the main body 10 , and one end of the liquid outlet 12 is located in the sealing groove 19 . When the shielding member 90 is located in the sealing position, the shielding member 90 is located in the sealing groove 19 , and at this time, the shielding member 90 can reliably seal the liquid outlet 12 .

Optionally, when the shielding member 90 is located at the sealing position, the shielding member 90 can cooperate with the gap between the side walls of the sealing groove 19 and can be reliably stopped on the liquid outlet 12, thereby achieving sealing of the liquid outlet 12.

Optionally, when the shielding member 90 is located at the sealing position, the shielding member 90 may have an interference fit with the side wall of the sealing groove 19 , that is, the shielding member 90 seals the sealing groove 19 , thereby achieving sealing of the liquid outlet 12 .

It should be noted that the sealing groove 19 can be arranged on a side of the liquid outlet 12 close to the dust inlet channel 11, that is, the sealing groove 19 is located in the dust inlet channel 11, and at this time, the shielding member 90 can be driven to move by the driving mechanism.

Alternatively, the sealing groove 19 can be arranged on a side of the liquid outlet 12 away from the dust inlet channel 11, that is, the sealing groove 19 is located outside the dust inlet channel 11. At this time, the shielding member 90 can be driven to move by the fan assembly 40, and the shielding member 90 can be separated from the sealing groove 19 under the action of gravity.

In one embodiment, the shielding member 90 is disposed on a plate body. When the fan assembly 40 is not working, the shielding member 90 is separated from the sealing groove 19 under the action of its own gravity. Only when the fan assembly 40 is working can the plate body be driven to rotate, so that the shielding member 90 is located in the sealing groove 19, thereby achieving sealing of the liquid outlet 12.

In one embodiment, the shielding member 90 is rotatably disposed on the body 10 so that the shielding member 90 can be switched between a sealing position and an open position. The shielding member 90 can be rotated relative to the body 10 by a driving mechanism to seal or release the liquid outlet 12. Alternatively, the shielding member 90 can be rotated under the action of the fan assembly 40 and can be rotated from the sealing position to the open position under the action of gravity.

In one embodiment, the shielding member 90 is disposed on a side of the main body 10 away from the dust inlet channel 11, that is, the shielding member 90 can be rotated from the sealing position to the opening position under the action of gravity.

In one embodiment, at least a portion of the shielding member 90 is a flexible member, which not only has a strong structural stability, but also can well seal the liquid outlet 12. Optionally, at least a portion of the shielding member 90 is rubber, and the shielding member 90 can be a soft rubber sheet. When the fan assembly 40 is running and generates negative pressure to suck up the soft rubber sheet, the liquid outlet 12 is blocked and a sealing effect is achieved. When the fan assembly 40 is not working, the soft rubber sheet returns to its original position, and the liquid can flow out of the dust inlet channel 11 through the liquid outlet 12, thereby avoiding a large amount of liquid remaining in the dust inlet channel 11.

In some embodiments, the liquid outlet hole 12 can be a circular hole, a triangular hole or a rectangular hole, and of course the liquid outlet hole 12 can also be a special-shaped hole, which is not limited here. The specific structural shape of the sealing groove 19 for accommodating the shielding member 90 can also be circular, triangular or rectangular, and of course the sealing groove 19 can also be a special-shaped groove.

In one embodiment, there are multiple liquid outlet holes 12 to increase the rate at which the liquid flows out and ensure that the liquid in the dust inlet channel 11 flows out reliably.

Optionally, there is at least one shielding member 90, and one shielding member 90 can shield a plurality of liquid outlet holes 12, thereby simplifying the structure.

Optionally, there are multiple shielding members 90, and the multiple shielding members 90 are disposed corresponding to the multiple liquid outlet holes 12 one by one, ensuring that each shielding member 90 independently seals each liquid outlet hole 12, thereby increasing the reliability of the seal.

In one embodiment, as shown in FIG. 11 , the dust collecting pile further includes: a baffle plate 60, which is arranged around the second filter assembly 50, and the baffle plate 60 is arranged opposite to the air outlet surface 52 of the second filter assembly 50 to form a baffle channel 61; wherein, an air outlet channel 62 is formed between the baffle plate 60 and the main body 10, and the bottom end of the baffle channel 61 is connected to the bottom end of the air outlet channel 62, that is, the airflow discharged from the air outlet surface 52 of the second filter assembly 50 can flow downward under the obstruction of the baffle plate 60, and flow into the air outlet channel 62 from the bottom of the baffle channel 61, thereby increasing the airflow path, thereby achieving the effect of noise reduction.

Specifically, as shown in Figure 11, the baffle plate 60 includes a first surface 63 and a second surface 64 relative to each other. The first surface 63 is arranged opposite to the air outlet surface 52 of the second filter assembly 50 to form a baffle channel 61, and the second surface 64 is arranged opposite to the main body 10 to form an air outlet channel 62; wherein, the bottom end of the baffle channel 61 is connected to the bottom end of the air outlet channel 62, so that the airflow discharged from the air outlet surface 52 can enter the air outlet channel 62 from the bottom end of the baffle channel 61, thereby increasing the airflow path.

In one embodiment, at least one of the body 10 and the second filter assembly 50 is connected to the baffle plate 60 to fix the baffle plate 60, that is, to ensure that the baffle plate 60 can stably achieve flow diversion.

In one embodiment, the upper side of the turbulence plate 60 is connected to at least one of the main body 10 and the second filter assembly 50 to prevent the top end of the turbulence channel 61 from being directly connected to the top end of the air outlet channel 62, so that the airflow cannot flow directly from the top end of the turbulence channel 61 into the air outlet channel 62.

Optionally, the baffle plate 60 may be connected to the body 10 such that the top end of the baffle plate 60 forms a sealed connection with the body 10.

Optionally, as shown in Figures 33 to 36, the top of the baffle plate 60 is fixedly connected to the second filter assembly 50, that is, the top of the baffle plate 60 can be connected to the frame 54 of the second filter assembly 50, so that the top of the baffle plate 60 forms a sealed connection with the second filter assembly 50.

In one embodiment, the bottom end of the baffle plate 60 is suspended so that the bottom end of the baffle channel 61 is connected to the bottom end of the air outlet channel 62, that is, the second filter assembly 50 and the main body 10 may not be in contact with the bottom end of the baffle plate 60, so that the airflow enters the air outlet channel 62 along the bottom end of the baffle plate 60.

Optionally, the bottom end of the baffle plate 60 may be lower than the bottom end of the air outlet surface 52, that is, it is sufficient as long as the bottom end of the baffle plate 60 is not sealed to the main body 10.

Optionally, the bottom end of the baffle plate 60 is higher than the bottom end of the air outlet surface 52 , that is, part of the airflow discharged from the air outlet surface 52 may not be stopped by the baffle plate 60 .

In one embodiment, as shown in FIG36 , a connecting channel 65 is provided on the baffle plate 60, and the baffle channel 61 is also connected to the air outlet channel 62 through the connecting channel 65, that is, the connecting channel 65 can directly allow part of the airflow to enter the air outlet channel 62, so that a large amount of airflow will not directly impact the baffle plate 60. On the basis of ensuring that the flow path of part of the airflow is increased, the noise caused by the airflow impact can also be avoided.

In some embodiments, the communication channel 65 is a through hole, and the through hole is located in the middle of the baffle plate 60, that is, the baffle channel 61 and the air outlet channel 62 are also connected through the through hole.

In some embodiments, the communication channel 65 is a notch, and the notch is recessed upward from the bottom end of the baffle plate 60, that is, it can be understood that an opening is formed on the baffle plate 60 for directly releasing the airflow.

In one embodiment, there are multiple connecting channels 65, thereby ensuring that airflows at different positions can directly enter the air outlet channel 62 through the connecting channels 65.

In one embodiment, the air outlet surface 52 includes a curved surface, the baffle plate 60 includes an arc-shaped plate arranged opposite to the curved surface, and a plurality of communication channels 65 are arranged at intervals along the circumferential direction of the arc-shaped plate. The shape of the baffle plate 60 is adapted to the air outlet surface 52, which can ensure reliable filtering and enable a reasonable layout of the structure.

In one embodiment, as shown in FIG. 2 and FIG. 7 , the dust collecting pile further includes: an air outlet plate 70, which is disposed above the second filter assembly 50, and is provided with a through hole 71, which is connected to the top of the air outlet channel 62, that is, the airflow entering the air outlet channel 62 flows upward, and then is discharged through the through hole 71 on the air outlet plate 70. Under the action of the turbulence plate 60, the airflow can be formed from top to bottom, and then discharged from bottom to top, so that the airflow path is greatly lengthened to achieve the purpose of noise reduction.

Optionally, the through hole 71 of the air outlet plate 70 can be directly connected to the air outlet surface 52 of the second filter assembly 50, that is, the baffle plate 60 can be removed, and the airflow from the air outlet surface 52 of the second filter assembly 50 can be directly discharged from the through hole 71 of the air outlet plate 70.
