Example

The embodiment of the present application provides an atomizing device 1. Please refer to FIG. 1 and FIG. 2. The atomizing device 1 includes a housing 10, a bracket 20, a circuit board 30, a microphone 40, and a sealing member 50. The atomizing device 1 can be a device for generating tiny droplets by dispersing liquid. The volume of the atomized droplets will also decrease, and they can easily pass through the gap. In order to improve the utilization rate of the tiny droplets and reduce the loss of the tiny droplets. The housing 10 The inner cavity 11 is formed, the housing 10 forms the inner cavity 11, the circuit board 30 is assembled on the housing 10, and the microphone 40 and the seal 50 are arranged in the inner cavity 11. Preferably, when the atomizer 1 is working, the atomizer 1 may involve heating and other processes, in order to avoid heat dissipation from the housing 10 and heat loss. Similarly, in order to avoid the high temperature on the surface of the housing 10, there is a risk. The housing 10 can be made of insulating material. For example, the housing 10 can be made of ceramic material. The ceramic material not only withstands high temperature, but also resists corrosion and has strong durability. The circuit board 30 is generally a sheet structure. The circuit board 30 needs to be installed and fixed in the inner cavity 11. The housing 10 is provided with a mounting hole 12, and the mounting hole 12 is used for positioning and installing between multiple parts such as the circuit board 30. In one embodiment, please refer to Figure 3, the circuit board 30 includes a first surface 31 and a second surface 32 opposite to the first surface 31, the second surface 32 faces the mounting hole 12, and the second surface 32 and the mounting hole 12 have a relative mounting position relationship. The second surface 32 can be positioned by using the mounting hole 12, so as to determine the mounting position relationship between the circuit board 30 and the housing 10. In order to prevent the circuit board 30 from obstructing the air circulation inside the inner cavity 11, the circuit board 30 is also provided with a first air hole 33, and the first air hole 33 can allow the air passing through the circuit board 30 to flow smoothly. The bracket 20 is arranged in the inner cavity 11, and the circuit board 30 is fixed to the bracket 20. In the inner cavity 11, the circuit board 30 is fixed by the bracket 20, and the circuit board 30 is not easy to move. In addition, the bracket 20 can be made of a flexible material, for example, the bracket 20 can be made of a material such as rubber, so as to reduce the damage caused by bumps and vibrations to the circuit board 30.

The circuit board 30 may include one or more (only one is shown in the figure) processors 301 and a memory 302 coupled to each other. Please refer to FIG4 , which takes the circuit board 30 as an example for description:

The processor 301 may include one or more processing cores. The processor 301 uses various interfaces and lines to connect various parts of the entire refrigeration device 30, and performs various functions and processes data by running or executing instructions, programs, code sets or instruction sets stored in the memory 302, and calling data stored in the memory 302. Optionally, the processor 301 can use digital signal processing (Digital Signal Processing, DSP), field programmable gate array (Field-Programmable Gate Array, FPGA), programmable logic array (Programmable Logic Array, PLA) or other processors. One less hardware form to implement.

The memory 302 may include a random access memory 302 (Random Access Memory, RAM) or a read-only memory 302 (Read-Only Memory). The memory 302 may be used to store instructions, programs, codes, code sets or instruction sets.

In this embodiment, please continue to refer to Figure 2. When the atomizer 1 is vibrated or bumped, components are easy to fall off from the circuit board 30. The seal 50 is filled between the bracket 20 and the circuit board 30. When the atomizer 1 is working, tiny droplets will also be generated in the inner cavity 11. The seal 50 can prevent the tiny droplets from escaping from the atomizer 1, and the seal 50 can also divide the inner cavity 11 into various parts. The seal 50 has a buffering effect. The seal 50 can reduce the loss of the circuit board 30 caused by external vibration, and the seal 50 can be filled between the shell 10 and the circuit board 30 to reduce the size of the gap between the shell 10 and the circuit board 30, prevent the gap from being too large, and the tiny droplets generated by atomization drill into the gap between the shell 10 and the circuit board 30, causing losses, thereby ensuring the smooth operation of the atomizer 1.

In this embodiment, please refer to FIG. 2, FIG. 3 and FIG. 5 together. The circuit board 30 includes a first area 34 and a second area 35 connected to each other. The first air hole 33 is opened in the first area 34. The atomizing device 1 also includes a power supply assembly 60. The power supply assembly 60 includes a power supply 61 and an oil tank 62. The power supply 61 and the oil tank 62 are generally large and heavy components in the atomizing device 1. Displacement and collision are easy to occur between the power supply 61 and the oil tank 62. The power supply 61 and the oil tank 62 are fixedly assembled. After the fixed assembly, the power supply 61 and the oil tank 62 are not easy to collide with each other, causing leakage of the oil tank 62. In order to reduce the number of assembly processes and ensure assembly accuracy and speed, the power supply 61 corresponds to the second area 35 and is electrically connected to the circuit board 30. The power supply 61 supplies power to the circuit board 30 to ensure the normal operation of the circuit board 30. The microphone 40 is arranged in the second area 35. The circuit board 30 can supply power to the microphone 40 to provide the power required for the normal operation of the microphone 40. The oil tank 62 corresponds to the first area 34. A heating wire 621 is disposed in the oil tank 62. The heating wire 621 is used to heat liquid substances such as tobacco oil. The heating wire 621 utilizes the characteristic of electricity to generate heat, so the heating wire 621 is provided to connect to the power supply assembly 60. And because the oil tank 62 needs to store heated smoke oil and other liquid substances, the closed oil tank 62 is prone to negative pressure, which can prevent the tiny droplets produced by the oil tank 62 from flowing out of the atomizer 1 smoothly. The first airway 101 is connected to the oil tank 62, and the air passing through the first airway 101 can make the tiny droplets flow out of the atomizer 1 smoothly.

In one embodiment, the heating wire 621 is provided with a pin extending toward the circuit board 30 for connecting to the power supply assembly 60. In order to ensure the safety of the connection circuit and protect the normal operation of the heating wire 621, a resistance wire is provided in the atomization device 1, and the power supply 61 and the heating wire 621 are electrically connected by the resistance wire. The resistance wire is connected to the power supply 61, and the power supply 61 provides current to both ends of the resistance wire. The resistance wire is connected to the heating wire 621, and the heating wire 621 is energized to generate heat. Liquids such as tobacco oil begin to turn into tiny liquids during the heating of the heating wire 621 for the user to inhale.

In this embodiment, please continue to refer to Figures 2 and 3. The common atomizer 1 requires manual operation by the user, and then the atomizer 1 works. In comparison, the manual operation by the user is cumbersome, and the reaction rate of the atomizer 1 is slow. The microphone 40 is electrically connected to the second surface 32, and the microphone 40 may include a differential capacitance sensor. When the user inhales the atomizer 1 during use, the change in the gas flow rate generated by the inhalation will affect the air pressure in the inner cavity 11, and the air pressure at both ends of the microphone 40 in the inner cavity 11 will change. The gas flow rate will affect the capacitance value at both ends of the microphone 40 and obtain the capacitance difference. The microphone 40 judges the trigger signal according to the capacitance difference, and adjusts the sensitivity according to the preset capacitance threshold. The microphone 40 is electrically connected to the second area 35, and the microphone 40 transmits the signal to the circuit board 30. In order to reduce unnecessary false touches, the microphone 40 is prevented from being affected by external airflow. The circuit board 30 is provided with a threshold, and it is judged whether the capacitance difference exceeds the threshold. When the capacitance difference exceeds the threshold, the circuit board 30 will control the atomization device 1 to heat up, atomize the tobacco oil to produce tiny droplets, and emit the smell of cigarettes, while controlling the corresponding display circuit to achieve the necessary display function; when the capacitance difference does not exceed the threshold, the circuit board 30 will not perform other operations and continue to maintain the standby mode.

In one embodiment, the working principle of the microphone 40 is that the gas flow rate affects the two ends of the microphone 40. The capacitance value is obtained and the capacitance difference is obtained, and the microphone 40 determines the trigger signal according to the capacitance difference. The microphone 40 detects the gas flow rate without the influence of airflow at one end away from the second airway 102, and uses this as a reference for comparison to generate the capacitance difference. Because of the positional relationship between the microphone 40 and the second surface 32, the circuit board 30 is provided with a second air hole 36, and the second air hole 36 runs through the first surface 31, and the second air hole 36 corresponds to the microphone 40. The end of the microphone 40 close to the second air hole 36 can detect the gas parameters without the influence of airflow through the second air hole 36, and the other end can obtain the gas parameters inside the second airway 102, and the capacitance at both ends changes according to the obtained gas parameters. The microphone 40 can obtain the capacitance difference at both ends, and convert the capacitance difference into parameters such as the pressure difference of the gas under certain rules.

In this embodiment, in order to ensure the rate of inhalation of the user, the diameter parameter of the pipe through which the air passes cannot be set too small. The microphone 40 is used to detect the change of the air entry rate. The airway diameter parameter will affect the rate at which the air enters the inner cavity 11, and the detection sensitivity of the microphone 40 will also be poor. Please refer to Figure 2. The shell 10 is provided with a first airway 101 and a second airway 102. The first airway 101 is connected to the mounting hole 12 and the first air hole 33. The second airway 102 is connected to the first airway 101 and is located on one side of the first airway 101. The microphone 40 is arranged at one end of the second airway 102 away from the first airway 101. The shell 10 is divided into the first airway 101 and the second airway 102, and the two are connected to each other. The user inhales to increase the gas flow rate of the first airway 101. According to the Bernoulli principle, under certain conditions, the gas flow rate of the first airway 101 is large, and the corresponding gas pressure is small. The air pressure in the first airway 101 decreases, and the gas in the second airway 102 connected to the first airway 101 flows into the first airway 101, and the gas flow rate and gas pressure of the second airway 102 change accordingly, and then the change in gas pressure is detected by the microphone 40 in the second airway 102. In one embodiment, the diameter of the first airway 101 can be set to be large, for example, the first airway 101 can be set to 5mm, to ensure the inhalation rate of the user; the diameter of the second airway 102 can be set to be small, for example, the second airway 102 can be set to 2mm, and the second airway 102 can be used to set the microphone 40. The microphone 40 can be in the second airway 102, and the user can use the smaller diameter of the second airway 102 under the same inhalation volume. The larger the diameter, the faster the airflow rate, and the more obvious the change in airflow can be detected by the microphone 40. In contrast, for the same inhalation volume, the detection effect of the microphone 40 is more obvious.

In this embodiment, liquids such as smoke oil may overflow from the oil tank 62 in the first airway 101. Since the second airway 102 is connected to the first airway 101, liquids such as smoke oil may overflow from the first airway 101 to the second airway 102. And because the size of the second airway 102 is set small, liquids such as smoke oil may block the second airway 102. Affecting the normal operation of the microphone 40 in the second airway 102. The second airway 102 is formed with a plurality of bending portions 90. The plurality of bending portions 90 can increase the length parameter of the second airway 102, and the number of positions where the microphone 40 can be set will also increase. The specific parameters can be adjusted according to the implementation requirements, and are not limited in this embodiment. And the plurality of bending portions 90 can reduce the flow of air in the second airway 102, avoiding the air flow rate of the first airway 101 from affecting the air flow rate of the second airway 102. The bending portion 90 will hinder the air from the first airway 101, preventing the detection of the microphone 40 from being damaged.

Specifically, please refer to FIG. 6 , the second air passage 102 includes a first air section 1021, a second air section 1022 and a third air section 1023, the first air section 1021 is bent toward one side of the first air passage 101 to form a first bending portion 901, the third air section 1023 is bent toward one side of the first air passage 101 to form a second bending portion 902, and the two ends of the second air section 1022 are connected to the first bending portion 901 and one end of the third air section 1023 away from the second bending portion 902. The second air passage 102 can have a larger size in a narrow space, further increase the length of the second air passage 102, increase the distance between the microphone 40 and the first air passage 101, and when the smoke oil in the oil tank 62 overflows to the first air passage 101, the second air passage 102 can have enough space to buffer the overflowed smoke oil to prevent the smoke oil from damaging the microphone 40. Protect the normal operation of the microphone 40 and prevent the first air passage 101 from affecting the microphone 40. Furthermore, the plurality of bent portions 90 can block the overflowing smoke oil, reduce the impact force of the overflowing smoke oil, and protect the normal operation of the microphone 40.

In this embodiment, in order to ensure that smoke can be discharged smoothly from the atomizer 1, the liquid forms tiny droplets in the airway. The user sucks the atomizer 1 to generate a driving force, and under the influence of the driving force, the tiny droplets smoothly flow out of the airway. The airway rises slowly and is smoothly inhaled into the mouth by the user. Under the influence of the driving force, external water vapor or other gases may enter the first airway 101 and the second airway 102. Water vapor entering the oil tank 62 will dilute the smoke oil. The heated water vapor and the atomized tiny droplets are inhaled by the user together. The water vapor may burn the user's mouth, and the mixture of the two will cause a bad taste and other effects. Please continue to refer to Figures 2 and 3. The atomizer 1 also includes an oil-absorbing cotton 80, which is arranged on the bracket 20 and is located on the side of the second surface 32 of the circuit board 30, and is located between the first air hole 33 and the first airway 101. The water vapor in the first airway 101 and the second airway 102 is filtered before passing through the second surface 32. The oil-absorbing cotton 80 can absorb the incoming water vapor and reduce the occurrence of poor taste caused by water vapor. In addition, liquids such as smoke oil may overflow from the oil tank 62. The smoke oil is absorbed by the oil-absorbing cotton 80 when passing through the second surface 32. The oil-absorbing cotton 80 can effectively prevent the smoke oil from leaking from the atomizer 1. Preferably, when water vapor from the outside enters the inner cavity 11, the water vapor will flow along the first air channel 101 to the circuit board 30 or along the second air channel 102 and the first air channel 101 in sequence to the circuit board 30. The water vapor will corrode the circuit board 30, thereby causing the circuit board 30 to fail to work properly. The connection between the second air channel 102 and the first air channel 101 is located on the side of the oil-absorbing cotton 80 away from the circuit board 30. The water vapor in the first air channel 101 and the second air channel 102 is filtered before passing through the second surface 32, and the oil-absorbing cotton 80 can absorb the incoming water vapor.

In this embodiment, in order to ensure that smoke can be discharged smoothly from the atomization device 1, the liquid forms tiny droplets in the inner cavity 11. The user inhales the atomization device 1 to generate a driving force on the airway. Under the influence of the driving force, the tiny droplets slowly rise along the airway and are smoothly inhaled into the mouth of the user. Under the influence of the driving force, external water vapor or other gases may enter the first airway 101 and the second airway 102. The water vapor entering the oil tank 62 will dilute the smoke oil. The heated water vapor and the atomized tiny droplets will be inhaled by the user together. The water vapor may scald the user's mouth, and the mixture of the two will cause effects such as poor taste. The connection between the second airway 102 and the first airway 101 is located on the side of the oil-absorbing cotton 80 away from the circuit board 30. The water vapor in the first airway 101 and the second airway 102 is filtered before passing through the second surface 32. The oil-absorbing cotton 80 can The water vapor entering the atomizer 1 is absorbed to reduce the occurrence of poor taste caused by the water vapor. In addition, the liquid such as the smoke oil may overflow from the oil tank 62, and the smoke oil is absorbed by the oil-absorbing cotton 80 when passing through the second surface 32. The oil-absorbing cotton 80 can effectively prevent the smoke oil from leaking from the atomizer 1.

In this embodiment, please refer to Figures 2 and 7 together. According to the usage habits of the consumer groups, the users have differences in the use of the atomizer 1, and the differences lie in the user's usage rate, single atomization volume and other related parameters. In order to change the user's atomization volume, the atomizer 1 also includes an air regulating device 63, and the air regulating device 63 is slidably assembled on the bracket 20 and is located at the mounting hole 12. The air regulating device 63 is used to adjust the atomization volume during the sliding process. The slidingly assembled air regulating device 63 can change the size of the air inlet duct of the atomizer, and then change the air intake rate. The air intake rate affects the rate of generation of tiny droplets. The user can adjust the atomization rate to avoid the atomization rate being too fast and causing waste. It also prevents the atomization rate from being too slow, and the atomization rate of the atomizer 1 cannot keep up with the user's intake, resulting in a very poor user experience. In one embodiment, the seal 50 further includes a plurality of third air holes 51, the third air holes 51 are connected to the first air holes 33, and the air regulating device 63 can slide to change the number of the third air holes 51, thereby changing the air intake rate of the third air holes 51 and adjusting the atomization rate, so that the atomization rate can be reasonably adjusted to reduce waste. And it can avoid the blockage of the third air hole 51, causing the atomization device 1 to be unable to work normally. For example, in the atomization device 1, the air regulating device 63 is provided with 3 third air holes 51, and the current air regulating device 63 blocks 1 third air hole 51. When the user uses the atomization device 1, it is found that the inhalation air flow rate of the atomization device 1 is small, and the air regulating device 63 is turned, so that the air regulating device 63 does not block the 3 third air holes 51 at all; and the user finds that the inhalation air flow rate of the atomization device 1 is large, and the air regulating device 63 is turned, so that the air regulating device 63 blocks 2 third air holes 51.

In another embodiment, a plurality of third air holes 51 are provided on the sealing member 50, and the plurality of third air holes 51 are distributed along the sliding direction of the air regulating device 63, and the diameters of the plurality of third air holes 51 are successively reduced or increased, and the third air holes 51 can be air holes on the bracket 20, and the sliding air regulating device 63 can change the third air holes 51 connected to the air holes, and the air regulating device 63 can slide to change the connection to a certain third air hole 51, and according to the different diameters of the connected third air holes 51, the air intake rate of the third air holes 51 is changed. Adjust the atomization rate.

In this embodiment, when the user adjusts the inhaled airflow rate of the atomizing device 1, the user needs to turn the air regulating device 63. However, when the user turns the air regulating device 63, the air regulating device 63 may not be accurately turned to the appropriate position because the space where the air regulating device 63 is located is small and not conducive to operation. Please continue to refer to Figures 2 and 7. The air regulating device 63 includes a fixed plate 631 and a protrusion 632. The protrusion 632 is arranged on the surface of the fixed plate 631. The fixed plate 631 is slidably assembled on the bracket 20. The protrusion 632 extends out of the mounting hole 12 and is used for external force to drive the fixed plate 631 to move, so that the fixed plate 631 selectively closes the plurality of third air holes 51 or shields at least one of the plurality of third air holes 51 during the sliding process. The user can turn the protrusion 632, and the protrusion 632 drives the fixed plate 631 to move to the appropriate position. It is convenient for users to adjust the air regulating device 63 , and it is avoided that the third air hole 51 is too small or the air regulating device 63 is too close to the sealing member 50 , which hinders the sliding setting of the air regulating device 63 .

Specifically, in order to ensure that the air conditioning device 63 can be slidably arranged, and to prevent foreign matter from entering between the air conditioning device 63 and the bracket 20, it cannot be disassembled and cleaned. The housing 10 includes a bottom plate 13, and the mounting hole 12 is arranged on the bottom plate 13. The surface of the bracket 20 facing the bottom plate is provided with a first buckle 633 and a second buckle 634, and the first buckle 633 and the second buckle 634 are arranged at intervals. A gap is formed between the first buckle 633 and the second buckle 634 and the surface of the bracket 20 facing the bottom plate, and the air conditioning device 63 is slidably assembled in the gap. The air conditioning device 63 can be slidably assembled to ensure the adjustment of the air intake rate of the third air hole 51, and the setting of the first buckle 633 and the second buckle 634 can disassemble the air conditioning device 63. In one embodiment, when foreign matter enters the third air hole 51, the air conditioning device 63 can be disassembled by using the first buckle 633 and the second buckle 634, and then the foreign matter in the third air hole 51 can be cleaned. After the cleaning is completed, the air regulating device 63 is assembled in the interval between the first buckle position 633 and the second buckle position 634 . The air regulating device 63 can adjust the air intake rate of the third air hole 51 .

In one embodiment, the air conditioning device 63 in the gap may be subjected to the first buckle position. The interference between the first buckle position 633 and the second buckle position 634, and the size parameter of the gap is small, which is not conducive to the user to adjust the air regulating device 63. The protrusion 632 extends from the gap between the first buckle position 633 and the second buckle position 634 and extends out of the mounting hole 12. When the user operates the air regulating device 63, the inconvenience caused by the size parameter of the gap can be reduced. Preferably, the end of the protrusion 632 away from the sealing member 50 can be provided with a pattern, and the pattern can increase the friction force, so that the user can use less force to adjust the air regulating device 63.

The embodiment of the present application provides an atomizing device 1, which uses a housing 10 to set up a first air channel 101 and a second air channel 102. The first air channel 101 for exchanging air with different effects and the second air channel 102 for detecting air parameters can protect the microphone 40 in the second air channel 102 from being damaged by a high-velocity airflow, and can also accurately detect changes in a low-velocity airflow. Protecting the normal operation of the microphone 40 and improving the accuracy of the detection of the microphone 40 can make the user's use effect better and increase the service life of the atomizing device 1.
