With the improvement of the living standard of people, more families begin to reduce the labor and improve the living quality by means of a wet and dry cleaning machine.

At present, the existing dry-wet two-purpose cleaning machine on the market is integrated, the floor brush mechanism forms negative pressure through the main motor to suck dirt on the ground into the recycling bin, and then the recycling bin is taken down for cleaning. In the existing wet and dry cleaning machine, the main motor and the recycling bin are usually arranged on the vertical machine body (such as the vertical handle), so that the weight of the vertical handle part is large, a user needs to use a large moment to control the movement of the cleaning machine, and the operation is inconvenient. Meanwhile, the main motor and the main body of the existing cleaning machine cannot be separated normally, so that the main motor cannot be used as an independent power unit to be externally connected with other accessories, the main motor can only clean the ground through the ground brush mechanism, and the ground brush mechanism has scene limitation due to the structure of the ground brush mechanism, so that the existing cleaning machine cannot clean the scenes such as corners, sofas, pets, desktops, vertical walls and the like.

Meanwhile, since the recycling bin is arranged on the vertical handle, when a user uses the cleaning machine, the angle of the machine body can be changed continuously along with the operation of the user, for example, when the floor at the bottom of furniture such as a sofa, a table, a chair and the like is cleaned, the machine body can have a larger inclination angle, and when the floor without an obstacle is cleaned, the inclination angle of the machine body is smaller. The change of fuselage inclination can cause the liquid in the recycling bin to rock constantly, and then makes water tank's water level sensor take place the false alarm, perhaps sewage flows from the bung hole of recycling bin, influences user's experience.

Therefore, how to improve the structure of the cleaning machine to meet the cleaning requirements of multiple scenes in daily life of people and improve the use experience of users becomes a problem to be solved in the field.

The technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be apparent that the described embodiments of the application are only some, but not all, embodiments of the application. All other embodiments, based on the embodiments of the application, which a person skilled in the art would obtain without making any inventive effort, are within the scope of the application.

Please refer to fig. 1 to 10 together. In the present embodiment, the cleaning device a includes at least a cleaning assembly 1 and a floor brush base 2. The cleaning assembly 1 comprises a body 11, an external module 12 and a recovery module 13, wherein the external module 12 and the recovery module 13 are arranged in the body 11; the external module 12 has a first pair of interfaces 121 and a first passage 123, wherein the first pair of interfaces 121 and the first passage 123 communicate such that outside air can enter the first passage 123 through the first pair of interfaces 121, and the recovery module 13 communicates with the first passage 123. The floor brush base 2 is provided with a rolling brush assembly 21 and a second passage 211, the body 11 is detachably fixed on the floor brush base 2, and when the body 11 is fixed on the floor brush base 2, the second passage 211 is communicated with the first pair of interfaces 121, so that garbage cleaned by the rolling brush assembly 21 sequentially passes through the second passage 211, the first pair of interfaces 121 and the first passage 123 and enters the recovery module 13.

In practical use, the second passage 211 in the ground brush base 2 exists as a recovery air duct of the roller brush assembly 21, and one end of the second passage 211 is located near the roller brush assembly 21, and the other end of the second passage 211 is provided with a screw thread or claw-type docking mechanism that mates with the first pair of interfaces 121. When the body 11 is fixed on the brush base 2 by the fastening member, the second passage 211 may be tightly locked with the first pair of interfaces 121 by the above-mentioned abutting mechanism, so far, as shown by the arrow in fig. 10, a complete recovery air duct is established between the brush base 2 and the cleaning assembly 1, and the recovery air duct starts from an end of the second passage 211 near the rolling brush assembly 21 and ends with the recovery module 13.

In the present embodiment, the first pair of interfaces 121 corresponds to an interface for connecting an external accessory, and the brush base 2 corresponds to an external accessory. Based on the above-mentioned idea, the cleaning assembly 1 may be further externally connected with other accessories, in this scenario, the external connection module 12 is provided with a second pair of interfaces 122, where the second pair of interfaces 122 is in communication with the first passage 123, so that external air may enter the first passage 123 through the second pair of interfaces 122.

It should be noted that when the circumscribing module 12 is provided with the first pair of interfaces 121 and the second pair of interfaces 122, the first passage 123 will communicate with both the first pair of interfaces 121 and the second pair of interfaces 122, so when the second passage 211 is tightly locked with the first pair of interfaces 121, a shielding cover (not shown) at the second pair of interfaces 122 needs to be closed to avoid the air flow sucked from the second passage 211 from escaping from the second pair of interfaces 122.

In practical applications, the external module 12 may exist as one component, for example, the first pair of interfaces 121, the second pair of interfaces 122, and the first passage 123 are manufactured as one integral part by an injection molding process or a 3D printing technology. The first pair of interfaces 121 and the second pair of interfaces 122 may be respectively used as an inlet end of the first passage 123, and an outlet end 1231 of the first passage 123 is communicated with the recovery module 13, and when the recovery module 13 works, external air may enter the recovery module 13 through the first pair of interfaces 121/the second pair of interfaces 122 and the first passage 123 in sequence. The abutting ends of the first and second pairs of interfaces 121 and 122 are provided with screw or claw type abutting mechanisms, and accordingly, according to the structure of the abutting ends of the first and second pairs of interfaces 121 and 122, the portion of the external accessory connected with the abutting ends is provided with corresponding abutting members, so that the external accessory can be tightly locked with the first and second pairs of interfaces 121 and 122 through the abutting members. Further, the abutting ends of the first and second pairs of interfaces 121 and 122 are provided with sealing rubber rings to improve the air tightness when the external accessory is connected with the first and second pairs of interfaces 121 and 122.

In one achievable embodiment, the recovery module 13 comprises a power unit 131 and a recovery tank 132; the recycling bin 132 is provided with an air inlet channel 13221 and an air outlet channel 13222, wherein the air outlet channel 13222 is communicated with the power unit 131, and the recycling bin 132 is detachably connected with the body 11; when the recycling bin 132 is connected to the body 11, the air inlet channel 13221 is communicated with the first channel 123, and under the action of the power unit 131, the external air flows through the first channel 123, the air inlet channel 13221 and the air outlet channel 13222 in sequence.

The power unit 131 may include a main motor 1311, a control unit 1312, and a power source 1313, the main motor 1311 being in communication with an air outlet passage 13222 in the recovery tub 132 through a socket joint 13111, and when the main motor 1311 operates, the main motor 1311 may pump out air in the recovery tub 132 through the air outlet passage 13222, thereby generating negative pressure in the recovery tub 132 so that external air may sequentially flow through the first passage 123, the air inlet passage 13221, and the air outlet passage 13222.

It should be noted that, the power unit 131 may be powered by a lithium battery mode or an external power mode. When the power unit 131 adopts a lithium battery mode to supply power, the power source 1313 is a lithium battery component; when the power unit 131 is powered by the external power mode, the power source 1313 is a power line module.

In practical applications, in order to facilitate the cleaning device a to clean the space with limited height such as the sofa bottom and the bed bottom, the overall height of the cleaning assembly 1 needs to be reduced as much as possible, and for this purpose, the recovery module 13 may be arranged horizontally to reduce the height of the recovery module 13. In particular, in one possible embodiment, the recycling module 13 comprises a power unit 131 and a recycling bin 132 arranged side by side, and the projections of the power unit 131 and the recycling bin 132 in the vertical direction overlap at least partially. In other words, the relative positions of the power unit 131 and the recovery tub 132 in the body 11 are not in an up-down relationship, but are placed side by side in the body 11. Further, the main motor 1311 of the power unit 131 is transversely disposed in the body 11 (i.e., the power output shaft of the main motor 1311 is horizontally disposed in the body 11) to further reduce the height of the recovery module 13.

Optionally, the air outlet passage 13222 in the recycling bin 132 is disposed in the body 11 in a substantially horizontal state, and the air outlet passage 13222 extends at least a distance in a horizontal direction to increase a distance between the main motor 1311 and the recycling bin 132 as much as possible, so as to avoid that sewage in the recycling bin 132 is sucked into the main motor 1311 when the main motor 1311 is started.

The recycling bin 132 may adopt a modular structure, and specifically, the recycling bin 132 may be composed of three separable modules including a top cover plate 1321, an air duct module 1322 and a bin body 1323, so as to facilitate the user to clean the recycling bin 132 daily. The top cover plate 1321 is used for sealing the barrel body 1323, the air duct module 1322 is located between the top cover plate 1321 and the barrel body 1323, and the air duct module 1322 is integrated with an air inlet channel 13221 and an air outlet channel 13222. In practical applications, to facilitate the cleaning of the air intake passage 13221 and the air outlet passage 13222, the air intake passage 13221 is configured to: two openings are formed on the substrate of the air duct module 1322, the two openings are taken as end points, the two openings extend upwards along the substrate of the air duct module 1322 to form annular protrusions, and the height of the annular protrusions is set based on the distance between the top cover plate 1321 and the substrate of the air duct module 1322, so that when the top cover plate 1321, the air duct module 1322 and the barrel 1323 are combined together, the annular protrusions just abut against the top cover plate 1321.

It should be noted that, two openings are formed on the substrate of the air duct module 1322, one opening is used as an air flow upstream port of the air intake channel 13221, and the other opening is used as an air flow downstream port of the air intake channel 13221. The air outlet passage 13222 is configured in a similar manner to the air inlet passage 13221, and will not be described herein.

The barrel 1323 is provided with an air inlet transition section 13231 and an air outlet transition section 13232, wherein one end of the air inlet transition section 13231 is communicated with the outlet end 1231 of the first passage 123, and the other end of the air inlet transition section 13231 is communicated with the air flow upstream port of the air inlet passage 13221. Accordingly, one end of the air outlet transition 13232 communicates with the airflow downstream port of the air outlet passage 13222, and the other end of the air outlet transition 13232 communicates with the socket 13111. When the main motor 1311 operates, the external air will flow through the first/second pair of interfaces 121/122, the first passage 123, the outlet end 1231, the air inlet transition 13231, the air inlet passage 13221, the air outlet passage 13222, the air outlet transition 13232, the socket 13111, and the main motor 1311 in order.

In one implementation, filter tray 1324 is mounted in barrel 1323 of recycling bin 132, filter tray 1324 is located below air intake passage 13221, and the projection of air intake passage 13221 on the horizontal plane overlaps the projection of filter tray 1324 on the horizontal plane, while the projection of air outlet passage 13222 on the horizontal plane does not overlap the projection of filter tray 1324 on the horizontal plane. The dashed line portions in fig. 1 and 5 are used to illustrate the relative positions of the inlet air passage 13221, the outlet air passage 13222, and the filter tray 1324 in the recovery tub 132.

In practical application, filter disc 1324 may be made of stainless steel or plastic, and a plurality of holes are formed in the disc body of filter disc 1324, and the diameters of the holes may be empirically measured. Since filter disc 1324 is located below air intake passage 13221, and the projection of air intake passage 13221 on the horizontal plane overlaps the projection of filter disc 1324 on the horizontal plane, and the projection of air outlet passage 13222 on the horizontal plane does not overlap the projection of filter disc 1324 on the horizontal plane, when the garbage cleaned by the external accessory enters air intake passage 13221 through first passageway 123, the garbage will first fall into filter disc 1324 under the action of gravity, then under the filtering action of the sieve holes of filter disc 1324, the solid garbage will remain in filter disc 1324, the liquid garbage will fall into barrel 1323, and the gas will enter air outlet passage 13222.

In one possible embodiment, to avoid that the waste entering the air intake passage 13221 enters the air outlet passage 13222 without being filtered by the filter tray 1324, the relative positions of the air intake passage 13221 and the filter tray 1324 may be configured to: the projection of the air flow downstream port of the air intake passage 13221 on the horizontal plane is located within the projection range of the filter tray 1324 on the horizontal plane, and a prescribed gap exists between the bottom of the air flow downstream port and the top of the filter tray 1324. Thus, filter tray 1324 and air intake passage 13221 may cooperate to form a relatively closed path that allows debris entering air intake passage 13221 to be drawn directly into air outlet passage 13222 when it is dislodged from the downstream air flow port of air intake passage 13221, but must first fall into filter tray 1324. Further, the gap between the bottom of the downstream port of the air intake passage 13221 and the top of the filter tray 1324 may be negative, i.e., the downstream port of the air intake passage 13221 may extend into the filter tray 1324. It should be noted that when the downstream air flow port of air intake passage 13221 extends into filter tray 1324, there is no direct contact between the downstream air flow port and filter tray 1324 to avoid interfering with the filtering operation of filter tray 1324.

Optionally, the bottom of the upstream port of air outlet passage 13222 is lower than the top of filter tray 1324, i.e., the interface of the upstream port of air outlet passage 13222 and filter tray 1324 is located below the top of filter tray 1324. As such, when the main motor 1311 draws air from the recovery tub 132 through the air outlet passage 13222, the air pressure in the space below the interface in the recovery tub 132 will be less than the air pressure in the space above the interface, so that the air in the air inlet passage 13221 flows into the tub 1323 through the mesh holes in the filter tray 1324 without escaping from the top of the filter tray 1324. Accordingly, the debris in the intake passage 13221 will not escape from the top of the filter tray 1324.

To further enhance the filtering effect of the filter tray 1324, in one embodiment, the body 11 is provided with a rotation member 111, and when the recovery tub 132 is coupled to the body 11, the rotation member 111 may be coupled to the filter tray 1324 such that the filter tray 1324 may be rotated by the rotation member 111. Specifically, a rotatable base 1325 is provided at the bottom of the tub 1323, the filter tray 1324 is installed in the tub 1323 through the base 1325, and simultaneously, a rotating member 111 is provided at a position of the body 11 opposite to the base 1325, and the rotating member 111 can be rotated by the driving of the power unit 131. The rotating member 111 and the base 1325 are provided with a clamping member matched with each other, so that when the recycling bin 132 is connected with the body 11, the rotating member 111 can be tightly fixed with the base 1325, and when the rotating member 111 rotates under the driving of the power unit 131, the rotating member 111 drives the base 1325 to synchronously rotate, and the filter disc 1324 rotates together under the driving of the base 1325. As filter disk 1324 rotates, liquid debris remaining within filter disk 1324 will be thrown out of the openings by centrifugal force and fall into tub 1323. By rotating filter disk 1324 by rotating member 111, filter disk 1324 can separate solid and liquid waste better.

Referring to fig. 1 and fig. 7 to 14, in one implementation, the cleaning assembly 1 further includes a cleaning water tank 14 and a water supply module 15, wherein the water supply module 15 is connected to the cleaning water tank 14 for pumping the cleaning water in the cleaning water tank 14 into an external accessory. For example, when the external accessory is connected to the first or second pair of the interfaces 121 or 122, the water inlet of the external accessory communicates with the water supply module 15, so that the liquid in the fresh water tub 14 may flow to the external accessory through the water supply module 15.

The water supply module 15 includes a three-way valve 152, and the three-way valve 152 includes a valve body 1521 and a valve body 1522 having a cavity. The valve body 1522 is provided with a first port 15221, a second port 15222, and a third port 15223 located between the first port 15221 and the second port 15222, and the first port 15221, the second port 15222, and the third port 15223 are respectively in communication with the cavity of the valve body 1522; the valve core 1521 is located inside the cavity of the valve body 1522, and the valve core 1521 may control the open/closed states of the first port 15221 and the second port 15222, and in particular, when the valve core 1521 switches the first port 15221 from the closed state to the open state, the valve core 1521 may simultaneously switch the second port 15222 from the open state to the closed state. Accordingly, when the spool 1521 switches the first port 15221 from the open state to the closed state, the spool 1521 may simultaneously switch the second port 15222 from the closed state to the open state.

Optionally, the valve element 1521 includes a first valve plate 15211, a second valve plate 15212, and an elastic member 15213, wherein the first valve plate 15211 is located near a first port 15221 of the valve body 1522, the second valve plate 15212 is located near a second port 15222 of the valve body 1522, and the first valve plate 15211 and the second valve plate 15212 are compressively connected together by the elastic member 15213. Specifically, the first valve plate 15211 is configured to: the outer profile of the first valve plate 15211 matches the inner cross section of the first port 15221 such that the first valve plate 15211 may move within the first port 15221 such that the first valve plate 15211 may completely seal the first port 15221 when the first valve plate 15211 has fully entered the first port 15221. The second valve plate 15212 has a similar structure to the first valve plate 15211, and the second valve plate 15212 may completely seal the second port 15222 when all of the second valve plate 15212 is inserted into the second port 15222.

In practical applications, when the valve core 1521 is placed in the cavity of the valve body 1522, the first valve plate 15211 is located near the first port 15221 of the valve body 1522, while the second valve plate 15212 is located near the second port 15222 of the valve body 1522, one end of the elastic member 15213 is connected to the first valve plate 15211, and the other end of the elastic member 15213 is connected to the second valve plate 15212. When the first valve plate 15211 is subjected to an external force directed to the second valve plate 15212, the first valve plate 15211 compresses the elastic member 15213, so that the elastic member 15213 can push the second valve plate 15212 to move in the direction of the external force, and the second valve plate 15212 can enter the second port 15222 under the action of the elastic member 15213, thereby completely sealing the second port 15222. Accordingly, when the first valve plate 15211 of the second valve plate 15212 is subjected to an external force directed toward the first valve plate 15211, the second valve plate 15212 compresses the elastic member 15213, so that the elastic member 15213 may push the first valve plate 15211 to move in the direction of the external force, and the first valve plate 15211 may enter the first port 15221 under the action of the elastic member 15213, thereby completely sealing the first port 15221. It should be noted that when the second valve plate 15212 fully seals the second port 15222, the first valve plate 15211 will be away from the first port 15221, thereby leaving the first port 15221 in a fully open state; accordingly, when the first valve plate 15211 fully seals the first port 15221, the second valve plate 15212 will be away from the second port 15222, thereby leaving the second port 15222 in a fully open state.

In the present embodiment, when the body 11 is fixed to the brush base 2, the water inlet 24 of the brush base 2 communicates with the water supply module 15 so that the liquid in the fresh water tub 14 flows toward the brush base 2 through the water supply module 15. Specifically, the floor brush base 2 is provided therein with an upwardly protruding water inlet 24, and the position of the water inlet 24 in the floor brush base 2 is configured to: when the body 11 is fixed on the brush base 2 through the clamping piece, the water inlet 24 can be abutted with the first valve plate 15211 in the three-way valve 152 and push the first valve plate 15211 to move along the direction pointing to the second valve plate 15212, and when the external accessory is in butt joint with the first pair of interfaces 121, the water inlet 24 is completely inserted into the first port 15221. Thus, as shown by the arrow in fig. 9, when the water pump 151 in the cleaning assembly 1 starts to operate, the cleaning liquid pumped by the water pump 151 will flow through the third port 15223 and the first port 15221 in sequence and into the water inlet 24, and then the cleaning liquid will be sprayed to the surface of the object to be cleaned and the rolling brush assembly 21 through the water supply line in the floor brush base 2.

In one possible embodiment, the floor brush base 2 may have a separate power unit to power the roller brush assembly 21; in another embodiment, the floor brush base 2 may not be provided with a separate power unit, but the power unit 131 in the cleaning assembly 1 may be used to power the roller brush assembly 21. When the rolling brush assembly 21 is powered by the power unit 131 in the cleaning assembly 1, a power conversion module is also arranged between the floor brush base 2 and the cleaning assembly 1, and the power conversion module can be manually connected by a user, for example, a power plug is arranged in the floor brush base 2, a power socket is arranged in the cleaning assembly 1, and after the body 11 is fixed on the floor brush base 2, the user inserts the power plug into the power socket; the power conversion module may also be automatically connected when the body 11 is fixed on the floor brush base 2, for example, a metal contact piece is provided in the floor brush base 2, and a metal contact piece is also provided on the body 11 of the cleaning assembly 1 corresponding to the position of the metal contact piece, so that when the body 11 is fixed on the floor brush base 2, the metal contact piece on the floor brush base 2 will contact with the metal contact piece on the body 11, so that the power unit 131 in the cleaning assembly 1 can provide power to the rolling brush assembly 21.

It should be noted that, the specific structures of the rolling brush assembly 21, the water supply pipeline, and the recovery air duct in the floor brush base 2 may refer to the prior art, and will not be described herein.

Referring to fig. 11 to 14 together, in one embodiment, the cleaning device a includes at least a cleaning assembly 1 and an accessory brush 3. The cleaning assembly 1 comprises a body 11, an external module 12 and a recovery module 13, wherein the external module 12 and the recovery module 13 are arranged in the body 11; the circumscribing module 12 has a second pair of interfaces 122 and a first passage 123, wherein the second pair of interfaces 122 and the first passage 123 are in communication such that ambient air can enter the first passage 123 through the second pair of interfaces 122 and the recycling module 13 is in communication with the first passage 123. The accessory brush 3 comprises a suction nozzle 31, a suction channel 32 and a clamping piece 33 for connecting the cleaning device, one end of the suction channel 32 is connected with the suction nozzle 31, and the clamping piece 33 is arranged at the other end of the suction channel 32. When the accessory brush 3 is fixed on the body 11 through the clamping piece 33, the suction channel 32 is communicated with the second pair of interfaces 122 in the external module 12, so that garbage cleaned by the accessory brush 3 can sequentially pass through the suction nozzle 31, the suction channel 32, the second pair of interfaces 122 and the first passage 123 and enter the recovery module 13.

In practical application, the suction channel 32 in the attachment brush 3 is used as a recovery air channel of the attachment brush 3, and the middle section of the suction channel 32 is made of flexible material, and the section of flexible pipe can be bent under the action of external force, so that the suction channel 32 has a plurality of operation angles. A handle 34 is also provided in the suction channel 32 at an end remote from the suction nozzle 31 to facilitate the user in mounting the accessory brush 3 on the body 11 or in removing the accessory brush 3 from the body 11. When the accessory brush 3 is fixed on the main body 11 by the clamping member 33, the suction channel 32 can be tightly locked with the second pair of interfaces 122 by the clamping member 33, so that a complete recovery air channel is established between the accessory brush 3 and the cleaning assembly 1, as shown by an arrow in fig. 14, wherein the recovery air channel takes the suction nozzle 31 as a starting point and takes the main motor 1311 as a finishing point.

It should be noted that, since the first passage 123 communicates with both the first pair of ports 121 and the second pair of ports 122, when the suction channel 32 is tightly locked with the second pair of ports 122, the shutter plate at the first pair of ports 121 needs to be closed to avoid the air flow sucked from the suction channel 32 from escaping from the first pair of ports 121. Further, the suction passage 32 may be configured to: the suction channel 32 is inserted into the second pair of ports 122 and enters the interior of the first passage 123 to achieve a tight lock with the second pair of ports 122, and the suction channel 32 enters one end of the interior of the first passage 123, which ends in a closed structure, with openings provided on the upper side walls of the closed ports. In this way, when the suction passage 32 is inserted into the interior of the first passage 123, the passage between the first passage 123 and the first pair of ports 121 can be blocked by the closed port of the suction passage 32, so that the air flow sucked from the suction passage 32 can be further prevented from escaping from the first pair of ports 121.

The end of the suction channel 32 that interfaces with the second pair of interfaces 122 is also provided with a water inlet 35, the position of the water inlet 35 in the suction channel 32 being configured to: when the suction channel 32 is docked with the second pair of interfaces 122, the water inlet 35 may abut the second valve plate 15212 in the three-way valve 152 and urge the second valve plate 15212 to move in a direction toward the first valve plate 15211, and when the suction channel 32 is docked with the second pair of interfaces 122, the water inlet 35 is fully inserted into the second port 15222. Thus, as shown by the arrow in fig. 13, when the water pump 151 in the cleaning assembly 1 starts to operate, the cleaning liquid pumped by the water pump 151 will flow through the third port 15223 and the second port 15222 in sequence and into the water inlet 35, and then the cleaning liquid will be sprayed to the surface of the object to be cleaned and the suction head through the water supply line in the accessory brush 3.

It should be noted that the specific structures of the suction nozzle 31, the suction passage 32, and the water supply line in the attachment brush 3 may refer to the prior art, and will not be described herein.

In practical applications, when the recovery tank and the main motor (e.g. a vacuum pump) are simultaneously disposed on the machine body or the floor brush base, the main motor is usually directly connected to the recovery tank, which results in a relatively short air duct between the main motor and the recovery tank. When the main motor is started, sewage in the recovery tank is easily sucked into the main motor, so that the main motor is damaged.

To solve the above-mentioned problems, as shown in fig. 15 to 17, in one possible embodiment, the cleaning device a includes at least a cleaning assembly 1, a floor brush base 2, and an upright handle 22. The cleaning assembly 1 comprises an external module 12 and a recycling bin 132, wherein the external module 12 is provided with a first pair of interfaces 121 and a first passage 123, and the first pair of interfaces 121 are communicated with the first passage 123, so that external air enters the first passage 123 through the first pair of interfaces 121. The floor brush base 2 has a roller brush assembly 21 and a second passage 211, wherein the upright handle 22 is rotatably connected to the floor brush base 2, the external module 12 is detachably fixed to the upright handle 22, and the recovery bucket 132 is detachably fixed to the floor brush base 2.

When the recycling bin 132 is fixed on the floor brush base 2 and the external module 12 is fixed on the upright handle 22, the second passage 211 is communicated with the first pair of interfaces 121, and the recycling bin 132 is communicated with the first passage 123, so that the garbage cleaned by the rolling brush assembly 21 sequentially passes through the second passage 211, the first pair of interfaces 121 and the first passage 123 and enters the recycling bin 132.

In practice, part of the structure of the upright handle 22 may be configured as a hollow tube, and the hollow tube is provided with two openings. The positions of the two openings are adapted to the positions of the first pair of connectors 121 and the position of the air outlet end of the second passage 211, so that one of the openings is in communication with the second passage 211 of the brush base 2, and the other opening is in communication with the first passage 123 of the external module 12 when the external module 12 is fixed to the upright handle 22. Thus, the second passageway 211, the hollow conduit of the upstanding handle 22, and the first passageway 123 collectively comprise a recovery air duct.

Alternatively, in another embodiment, the second passage 211 and the first pair of connectors 121 may be connected by a hose, that is, after the external module 12 is fixed on the upright handle 22, a section of separate hose is used to connect the second passage 211 and the first pair of connectors 121, so as to construct a complete recovery air duct.

Further, the external module 12 further has a power unit 131, and the recycling bin 132 has an air inlet channel 13221 and an air outlet channel 13222. When the recovery tub 132 is fixed on the floor brush base 2 and the external module 12 is fixed on the upright handle 22, the air inlet passage 13221 communicates with the first passage 123, and the air outlet passage 13222 communicates with the power unit 131, so that the external air sequentially flows through the first passage 123, the air inlet passage 13221 and the air outlet passage 13222 under the action of the power unit 131, and finally enters the recovery tub 132. The specific implementation structure of the cleaning assembly 1 and the floor brush base 2 can be referred to in the above embodiments, and will not be described herein.

Compared with the embodiment in which the recycling bin 132 is disposed inside the body 11, the recycling bin 132 is independently disposed outside the body 11, the recycling bin 132 is detachably connected with the body 11, and when the recycling bin 132 is connected with the body 11, the recycling bin 132 is disposed below the body 11, and meanwhile, the main motor 1311 in the body 11 is disposed at the upper half of the body 11, so as to increase the distance between the main motor 1311 and the recycling bin 132 as much as possible, thereby avoiding that sewage in the recycling bin 132 is sucked into the main motor 1311 when the main motor 1311 is started. The application also provides an operation method of the cleaning device, the cleaning device A at least comprises a cleaning assembly 1 and a ground brush base 2, wherein the cleaning assembly 1 is detachably fixed on the ground brush base 2, and the method comprises the following steps:

judging whether the cleaning component is fixed on the floor brush base or not;

And if the cleaning component is fixed on the floor brush base, switching the control switch to the floor brush base so as to control the operation of the cleaning device through the floor brush base.

In an implementation manner, the cleaning assembly 1 and the floor brush base 2 are both provided with control switches, and the MCU module in the cleaning assembly 1 can automatically determine whether to switch the control switches to the control switches on the cleaning assembly 1 according to the connection condition of the cleaning assembly 1 and the floor brush base 2. Specifically, the MCU module in the cleaning assembly 1 first determines whether the cleaning assembly 1 is fixed on the floor brush base 2, if the MCU module determines that the cleaning assembly 1 is already fixed on the floor brush base 2, the MCU module may close the control switch on the cleaning assembly 1 and send an electrical signal to the floor brush base 2 to open the control switch on the floor brush base 2, and further switch the control switch of the combined cleaning apparatus a to the floor brush base 2, so as to control the operation of the cleaning assembly 1 and the floor brush base 2 through the control switch of the floor brush base 2; if the MCU module judges that the cleaning assembly 1 is not fixed on the floor brush base 2, the MCU module does not send an electric signal, and the cleaning assembly 1 and the floor brush base 2 control the operation of the equipment through the control switch of the cleaning assembly and the floor brush base respectively.

The present application also provides a method for operating a cleaning assembly, where the cleaning assembly 1 includes an external module 12, the external module 12 has a first pair of interfaces 121 and a second pair of interfaces 122, and the first pair of interfaces 121 and the second pair of interfaces 122 are respectively used for connecting external accessories, and the method includes:

judging whether the external connection module is connected with an external accessory or not;

If the external connection module is connected with the external accessory, judging whether to switch the control switch to the external accessory or not based on the connection position of the external accessory.

The cleaning assembly 1 and the external accessories are provided with control switches, and when a user needs to combine the cleaning assembly 1 with the external accessories for use, the MCU module in the cleaning assembly 1 can automatically judge whether the control switches need to be switched to the external accessories according to the connection condition of the external accessories.

In one implementation manner, the MCU module may first determine whether the external connection module 12 is connected with an external accessory, and when determining whether the external connection module 12 is connected with an external accessory, the MCU module may implement the following steps: first, electrical signals transmitted by motion sensors at the first pair of interfaces 121 and the second pair of interfaces 122 are detected; then, it is determined whether or not the external accessory is connected to the first pair of interfaces 121 and the second pair of interfaces 122 based on the above-described electrical signals.

In practical application, the motion sensor may be a hall sensor or a micro switch, and the motion sensor is exemplified as the micro switch. A micro switch is provided at both the first pair of interfaces 121 and the second pair of interfaces 122, and in one embodiment the micro switch is configured to: when the first and second pairs of interfaces 121 and 122 are not connected to external accessories, the micro switch does not transmit an electrical signal to the MCU module; when the first pair of interfaces 121 or the second pair of interfaces 122 are connected to external accessories, the micro switch is triggered, and the micro switch sends an electrical signal to the MCU module. When the MCU module detects the electrical signal sent by the micro switch at the first pair of interfaces 121 or the second pair of interfaces 122, it can determine that the micro switch at the first pair of interfaces 121 or the second pair of interfaces 122 has been triggered, and then the MCU module can determine that the first pair of interfaces 121 or the second pair of interfaces 122 has been connected with an external accessory.

After the MCU module determines that the external connection module 12 is connected with an external accessory, it may further determine whether to switch the control switch to the external accessory based on the location where the external accessory is connected. In particular, the micro-switch may be further configured to: the electrical signal characteristics sent by the micro-switches at the first pair of interfaces 121 are different from the electrical signal characteristics sent by the micro-switches at the second pair of interfaces 122. Thus, the MCU module can determine whether the external accessory is connected to the first pair of interfaces 121 or the second pair of interfaces 122 by recognizing and identifying the characteristics of the received electrical signals.

Switching logic is preset in the MCU module, for example, the switching logic preset in the MCU module is: if the first pair of interfaces 121 is connected with an external accessory, the control switch is switched to the external accessory, and the control switch on the external accessory controls the working state of the cleaning assembly 1 and the external accessory combination; if the second pair of interfaces 122 is connected with an external accessory, the control switch is not switched to the external accessory, and the control switch on the cleaning assembly 1 controls the working state of the cleaning assembly 1 and the external accessory combination.

Correspondingly, the preset switching logic in the MCU module may also be: if the second pair of interfaces 122 is connected with the external accessory, the control switch is switched to the external accessory, and the control switch on the external accessory controls the working state of the cleaning assembly 1 and the external accessory combination; if an external accessory is connected to the first pair of interfaces 121, the control switch is not switched to the external accessory, and the control switch on the cleaning assembly 1 controls the working state of the cleaning assembly 1 and the external accessory combination.

In one implementation, the micro-switches at the first and second pairs of interfaces 121 and 122 send electrical signals to the MCU module at all times, and the MCU module determines whether to switch the control switch to an external accessory based on the change in the electrical signals. Specifically, assuming that the micro switch at the second pair of interfaces 122 is not triggered, the input electrical signal detected by the MCU module is at a high level or a low level, when the external accessory is connected to the second pair of interfaces 122, the MCU module detects that the electrical signal is at a certain value greater than 0 and less than 3.3V/5V, based on the change of the electrical signal, the MCU module can determine whether the first pair of interfaces 121 or the second pair of interfaces 122 is connected to the external accessory, and further, the MCU module can determine whether to switch the control switch to the external accessory according to preset switching logic. The preset switching logic of the MCU module may refer to the relevant content in the above embodiment, which is not described herein.
