[0039] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0040] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0041] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0042] The atomizing device can be, for example, a medical atomizing device or an electronic cigarette. The atomizer in the atomizing device utilizes heat to atomize the atomizing matrix to generate an aerosol. Specifically, the atomizing device allows external air to enter the atomizing airway through suction. As the external air passes through the atomizing airway, the atomized matrix is heated and evaporated, and upon encountering the external air, condenses into liquid particles, thereby forming the aerosol.

[0043] During the puffing process, the atomizer generates airflow changes, which are detected by the airflow sensor in the activating airway of the sensing component. Based on the air pressure signal changes in the atomizing airway, the sensor outputs an electrical signal to the atomizer in the atomizer, activating the atomizer. However, the activating airway typically requires a complex air path, resulting in low product space utilization. Furthermore, because the airflow sensor is located in an environment with fluctuating airflow, activation is less sensitive.

[0044] In response to the above problems, the present application provides a sensing component that can simplify the starting airway structure of the airflow sensor, improve product space utilization, and enhance the sensitivity of the airflow sensor.

[0045] See also Figure 1 and Figure 2As shown, the sensing component 200 provided in this embodiment is used for the atomizing device 100 to start the atomizing device 100 through the sensing component 200. The atomizing device 100 includes a charging interface 15, through which the power supply unit 60 in the atomizing device 15 can be replenished with electric energy.

[0046] See also Figure 1-Figure 4 As shown, the atomizing device 100 is composed of an atomizer 10 and a bottom shell 20. The atomizer 10 is provided with an atomizing airway 1121. The atomizer 10 is connected to the bottom shell 20 to enclose an air inlet cavity 21 with the atomizer 10. The bottom shell 20 can be considered as a bottom shell having an opening 201 (such as Figure 4 As shown), the shell structure is closed at the other end. After being connected to the atomizer 10, the internal cavity structure is formed by the bottom shell 20 and the connection side of the atomizer 10 and the bottom shell 20. The cavity structure is the air inlet cavity 21, and the air inlet cavity 21 is connected to the atomizing airway 1121 of the atomizer 10.

[0047] An air inlet hole 22 and a connecting hole 23 are provided on the bottom shell 20. The air inlet hole 22 allows the external air to enter the air inlet chamber 21 when the atomizing device 100 is inhaling. The setting of the connecting hole 23 allows one side of the airflow sensor 30 to remain connected to the external atmosphere, so as to improve the sensitivity of the airflow sensor 30. For details, please refer to the subsequent embodiments.

[0048] See also Figure 2 As shown, the nebulizer 10 in the present application includes a liquid storage component 11 and an atomization component 12, wherein the liquid storage component 11 includes a liquid storage tank 111 and a liquid storage part 112, wherein the liquid storage tank 111 is a structure with an open port 1111 at the bottom and a conducting hole 1112 at the top, the liquid storage part 112 is installed inside the liquid storage tank 111, and the atomization airway 1121 is opened on the liquid storage part 112, and the atomization airway 1121 is kept in communication with the conducting hole 1112, and the generated aerosol is output through the conducting hole 1112 after passing through the atomization airway 1121.

[0049] The liquid storage member 112 is preferably made of cotton or fiber material, which can store the atomized matrix by adsorption and transfer the atomized matrix to the atomization component 12.

[0050] The atomization assembly 12 includes an atomization tube 121, a liquid guide part 122 and a heating part 123. The atomization tube 121 is inserted into the atomization airway 1121, and the liquid guide part 122 is installed in the atomization tube 121. The liquid guide part 122 is usually a hollow columnar structure with openings at both ends. The liquid guide part 122 can also be made of cotton or fiber material. The heating part 123 is installed in the internal cavity of the liquid guide part 122. The heating part 123 is usually a mesh heating wire structure, which can realize circumferential heating function. The airflow sensor 30 is electrically connected to the heating element 123. In response to the change in the air pressure signal of the atomizing airway 1121, the airflow sensor 30 outputs an electrical signal to the heating element 123 to start the operation of the heating element 123, thereby heating the atomizing matrix. After the external air enters the atomizing airway 1121 through the air inlet hole 22 and the air inlet cavity 21, there is a certain temperature difference between the temperature of the external air and the temperature of the atomizing matrix heated by the heating element 123, which can cause the heated atomizing matrix to condense to form liquid particles, thereby generating an aerosol.

[0051] In some embodiments, a liquid guide port is usually further provided on the atomizing tube 121, and part of the liquid guide member 122 extends to the outside of the atomizing tube 121 through the liquid guide port. After the atomizing tube 121 is installed inside the atomizing air channel 1121, the part of the liquid guide member 122 extending to the outside of the atomizing tube 121 through the liquid guide port can be made to fully contact the liquid storage member 112 to achieve conduction of the atomizing matrix. The heating member 123 can heat the atomizing matrix to generate an aerosol, and the generated aerosol is output to the outside of the atomizer through the atomizing tube 121, the atomizing air channel 1121, and the conducting hole 1112.

[0052] Continue to see Figure 1 As shown, the liquid storage assembly 11 also includes a bottom cover 113, which is usually provided with an atomizer seat 1131. A slot 1132 is provided in the atomizer seat 1131. The slot 1132 is an axially through hollow structure. The atomizer tube 121 is inserted into the slot 1132 of the atomizer seat 1131, and the bottom cover 113 is installed on the side of the liquid storage tank 111 where the opening 1111 is provided to close the opening 1111, thereby forming a cavity structure for placing the liquid storage component 112 through the bottom cover 113 and the liquid storage tank 111.

[0053] The bottom shell 20 and the bottom cover 113 are connected to each other, so that the bottom shell 20 and the bottom cover 113 enclose the air inlet cavity 21. Since the slot 1132 for inserting the atomizer tube 121 is an axially through hollow structure, the atomizer tube 121 and the air inlet cavity 21 can be kept in a connected state.

[0054] In this embodiment, the atomizer 10 further includes a housing 14 , the liquid storage assembly 11 and the atomization assembly 12 are both installed inside the housing 14 , the bottom end of the housing 14 is an open structure, and the bottom shell 20 is connected to the open structure at the bottom end of the housing 14 .

[0055] In one embodiment of the present application, the atomizer 10 further includes a nozzle 13, in which a nozzle channel 131 is provided. The nozzle 13 is mounted on a side of the liquid storage tank 111 where a conducting hole 1112 is provided, and the nozzle channel 131 is connected to the conducting hole 1112. When in use, the user inhales through the nozzle 13, so that a negative pressure is generated in the nozzle channel 131, the atomizing airway 1121, and the air inlet chamber 21. The airflow sensor 30 senses the airflow change in response to the air pressure change and outputs an electrical signal to the heater 123 in the atomizer 10 of the atomizer device 100 to trigger the heater 123 to work and heat the atomizing matrix. The external gas causes the heated atomizing matrix to condense to form liquid particles, thereby generating an aerosol. The generated aerosol is output to the outside of the atomizing device 100 through the nozzle channel 131.

[0056] During the aerosol delivery process, due to the influence of the transmission distance, the aerosol will condense and produce condensate due to heat exchange with the shell of the suction nozzle 13. In order to prevent the condensate from flowing back into the atomization airway 1121 and affecting the taste of the aerosol, in this embodiment, a liquid absorption member 132 is further provided between the suction nozzle channel 131 of the suction nozzle 13 and the conducting hole 1112 of the liquid storage tank 111 to absorb the condensate.

[0057] See also Figure 2-Figure 9 As shown, the sensing assembly 200 provided in this embodiment includes an airflow sensor 30 and a sensor bracket 40 .

[0058] The airflow sensor 30 is used to respond to the air pressure signal changes of the atomizing air channel 1121 of the atomizing device 100 and output an electrical signal to the heating element 123 in the atomizer 10 of the atomizing device 100 to trigger the heating element 123 to work and heat the atomized substrate.

[0059] The atomizing airway 1121 runs through the nebulizer 10, allowing the aerosol to be output to the outside of the nebulizer 10 through the atomizing airway 1121. Changes in the air pressure signal in the atomizing airway 1121 are generated by the user inhaling through the mouthpiece 13. During the inhalation process, external air enters the air inlet cavity through the air inlet hole 22 and is output through the atomizing airway 1121 and the mouthpiece channel 131, resulting in negative pressure in the mouthpiece channel 131, the atomizing airway 1121, and the air inlet cavity 21. The airflow sensor 30 senses the airflow changes and responds to the air pressure changes.

[0060] The sensor bracket 40 includes an installation cavity 41 and a accommodating cavity 42. The airflow sensor 30 is installed in the installation cavity 41. The accommodating cavity 42 is used to install the charging interface 16, and the accommodating cavity 42 can be connected to the external atmosphere through the connecting hole 23. The charging interface 16 is arranged in the installation cavity 42. The characteristic that the charging interface 16 needs to be connected to the outside world can be utilized to realize the function of connecting the first sensing side 31 of the airflow sensor 30 with the outside atmosphere.

[0061] See also Figure 3 and Figure 4 As shown, the airflow sensor 30 has a first sensing side 31 and a second sensing side 32, and the sensor bracket 40 is also provided with a first air duct 43 and a second air duct 44. The sensor bracket 40 is arranged in the air inlet cavity 21 enclosed by the bottom shell 20 and the atomizer 10. The first sensing side 31 is connected to the outside atmosphere through the first air duct 43 and the accommodating cavity 42, and the second sensing side 32 is connected to the atomizing air duct 1121 through the second air duct 44.

[0062] It should be noted that the first air channel 43 connects the mounting chamber 41 with the accommodating chamber 42, and the accommodating chamber 42 connects with the communicating hole 23, thereby allowing the first sensing side 31 to communicate with the outside atmosphere through the first air channel 43 and the accommodating chamber 42. The second air channel 44 connects the mounting chamber 41 with the air inlet chamber 21, thereby allowing the second sensing side 32 to communicate with the atomizing air channel 1121 through the second air channel 44.

[0063] When a user inhales through the mouthpiece 13, external air enters the air inlet chamber through the air inlet hole 22 and is discharged through the atomizing airway 1121 and the mouthpiece passage 131, causing a negative pressure to be generated in the mouthpiece passage 131, the atomizing airway 1121, and the air inlet chamber 21. The first sensing side 31 of the airflow sensor 30 senses the air pressure of the external atmosphere, and the second sensing side 32 senses the negative pressure of the air inlet chamber 21. This causes the airflow sensor 30 to respond to the air pressure signal of the atomizing airway 1121, thereby generating an electrical signal. This electrical signal is then output to the heater 123 in the atomizer 10 of the atomizing device 100, thereby activating the heater 123 to heat the atomizing substrate. Due to the temperature difference between the external air and the temperature of the atomizing substrate heated by the heater 123, the heated atomizing substrate condenses to form liquid particles, thereby generating an aerosol. The generated aerosol is then discharged from the mouthpiece 13 through the atomizing airway 1121 and the mouthpiece passage 131 under the action of the flowing airflow.

[0064] In this embodiment, when external air enters the air inlet cavity 21 through the air inlet hole 22 and causes the second sensing side 32 to sense the negative pressure change and generate a changing air pressure signal, the changing air pressure signal can be processed to generate a trigger signal for triggering the heating element 123 in the atomizer 10 to start. With this arrangement, only the second sensing side 32 of the airflow sensor 30 can sense the change in airflow, thereby improving the sensitivity of the airflow sensor 30.

[0065] In one embodiment, the airflow sensor 30 can generate a changing capacitance signal when the air pressure signal changes, and the capacitance signal can be processed to generate a trigger signal.

[0066] In this embodiment, the airflow sensor 30 can employ a parallel plate capacitor structure, where changes in air pressure cause the diaphragm to change, subsequently generating a varying capacitance signal. Alternatively, the current sensor 30 can employ an electret structure, with the plate positioned above the diaphragm, similarly generating a varying capacitance signal in response to changes in air pressure.

[0067] In this embodiment, the first sensing side 31 and the second sensing side 32 are only defined to illustrate that the airflow sensor 30 can generate a trigger signal according to the change of airflow, and there is no specific limitation on the position of the first sensing side 31 and the second sensing side 32 on the airflow sensor 30.

[0068] See also Figures 6-10 As shown, in this embodiment, the sensor bracket 40 includes a first end 45 and a second end 46 disposed opposite each other. The mounting cavity 41 and the accommodating cavity 42 both pass through the first end 45 and the second end 46. The first air channel 43 connects the mounting cavity 41 with the accommodating cavity 42, and the second air channel 44 connects the mounting cavity 41 with the atomizing air channel 1121. In a preferred embodiment, the first air channel 43 is disposed at the first end 43, and the second air channel 44 is disposed at the second end 46.

[0069] In this embodiment, the sensor bracket 40 is installed in the air inlet cavity 21 enclosed by the bottom shell 20 and the bottom cover 113. The second air duct 44 connects the installation cavity 41 with the atomization air duct 1121 through the air inlet cavity 21. The second end 46 of the sensor bracket 40 fits into the air inlet cavity 21 and cooperates with other structures to fit into the first end 45, thereby closing the installation cavity 41 and the accommodating cavity 42. Please refer to the subsequent embodiments for details.

[0070] See also Figure 2-Figure 4 As shown, the sensing component 200 also includes a first circuit board 53, the sensor bracket 40 is arranged on the first circuit board 53, and the first end 45 of the sensor bracket 40 is attached to the surface of the first circuit board 53, the airflow sensor 30 and the charging interface 15 are both connected to the first circuit board 53, and the air pressure change signal of the atomization airway 1121 responded by the airflow sensor 30 can be processed by the first circuit board 53 into a start signal to trigger the start of the heating element 123. After the charging interface 15 is connected to the power supply through the charging cable, the energy supply unit in the atomization device can be charged through the first circuit board 53.

[0071] In this embodiment, the through-type installation cavity 41 and the accommodating cavity 42 are sealed by the first circuit board 53 being attached to the first end 45 of the sensor bracket 40 and the cavity wall of the air inlet cavity 21 being attached to the second end 46 of the sensor bracket 40 .

[0072] Continue to see Figures 6-10As shown, the first end portion 45 is located between the mounting cavity 41 and the accommodating cavity 42 and is provided with a first connecting groove 431. The groove wall of the first connecting groove 431 and the first circuit board 53 enclose the first airway 43. The second end portion 46 is provided on the cavity wall of the atomizing device 100. The second end portion 46 is provided with a second connecting groove 441. The groove wall of the second connecting groove 441 and the cavity wall of the atomizing device 100 enclose the second airway 44. In this embodiment, the second end portion 46 is specifically provided on the cavity wall of the air inlet cavity 21 of the atomizing device 100, so that the groove wall of the second connecting groove 441 and the cavity wall of the air inlet cavity 21 enclose the second airway 44.

[0073] Of course, in other embodiments, the first air duct 43 may be a through-hole structure provided between the installation cavity 41 and the accommodating cavity 42, and the second air duct 44 may be a through-hole structure provided on the cavity wall of the installation cavity 41, which may also realize the conduction function.

[0074] When the first end portion 45 is connected to the first circuit board 53, in order to ensure sealing, as shown in FIG. Figure 6 and Figure 10 As shown, a first sealing portion 47 is further protruded from the first end portion 45, and the end of the first sealing portion 47 away from the second end portion 46 abuts against the first circuit board 53. The installation cavity 41, the accommodating cavity 42 and the first air duct 43 are all located inside the first sealing portion 47. In other words, the first sealing portion 47 is formed into an annular structure surrounding the installation cavity 41, the accommodating cavity 42 and the first air duct 43, and sealing is achieved by abutting against the first circuit board 53.

[0075] In this embodiment, the sensor bracket 40 is preferably made of silicone material, has a certain elastic deformation, and can achieve a sealing effect by abutting against the first circuit board 53.

[0076] like Figures 6-10 As shown, a retaining portion 421 is further provided on the side wall of the accommodating chamber 42. The retaining portion 421 is used to support the charging interface 15, thereby clamping the charging interface 15 to the retaining portion 421 by forming an interference fit between the retaining portion 421 and the charging interface 15. The retaining portion 421 is preferably provided so as to surround the side wall of the accommodating chamber 42. A notch 422 is also provided on the retaining portion 421. The notch 421 can connect the accommodating chamber 42 with the first air channel 43, thereby maintaining communication between the first air channel 43 and the accommodating chamber 42 and the external atmosphere.

The sensing component 200 is arranged inside the atomizer 10, and an atomization airway 1121 is also provided inside the atomizer 10. The airflow sensor 30 of the sensing component 200 can respond to changes in the air pressure signal in the atomization airway 1121 and output an electrical signal to the atomization device 100 to start the atomization device 100.

[0079] The interior of the atomizer 10 has an air inlet chamber 21 connected to the atomizing air duct 1121. A connecting hole 23 is opened on the atomizer 10, and the connecting hole 23 connects the air inlet chamber 21 with the outside atmosphere. The sensing component 200 is arranged in the air inlet chamber 21 at a position corresponding to the connecting hole 23, and the connecting hole 23 is connected to the installation chamber 21.

[0080] In a specific embodiment, Figure 1-Figure 4 As shown, the atomizing device 100 is composed of an atomizer 10 and a bottom shell 20. The atomizer 10 is provided with an atomizing airway 1121. The atomizer 10 is connected to the bottom shell 20 to enclose an air intake chamber 21 with the atomizer 10. The bottom shell 20 can be considered as a shell structure having an opening 201 at one end and a closed end. After being connected to the atomizer 10, the internal cavity structure is enclosed by the bottom shell 20 and the connection side of the atomizer 10 and the bottom shell 20. This cavity structure is the air intake chamber 21, which is in communication with the atomizing airway 1121 of the atomizer 10.

[0081] A connecting hole 23 is provided on the bottom shell 20 , and an air inlet hole 22 is also provided on the bottom shell 20 . The air inlet hole 22 allows external air to enter the air inlet cavity 21 when the atomizing device 100 is inhaling. The setting of the connecting hole 23 allows one side of the airflow sensor 30 to remain in communication with the external atmosphere, thereby improving the sensitivity of the airflow sensor 30 .

[0082] See also Figure 2 As shown, the nebulizer 10 in the present application includes a liquid storage component 11 and an atomization component 12, wherein the liquid storage component 11 includes a liquid storage tank 111 and a liquid storage part 112, wherein the liquid storage tank 111 is a structure with an open port 1111 at the bottom and a conducting hole 1112 at the top, the liquid storage part 112 is installed inside the liquid storage tank 111, and the atomization airway 1121 is opened on the liquid storage part 112, and the atomization airway 1121 is kept in communication with the conducting hole 1112, and the generated aerosol is output through the conducting hole 1112 after passing through the atomization airway 1121.

[0083] The liquid storage member 112 is preferably made of cotton or fiber material, which can store the atomized matrix by adsorption and transfer the atomized matrix to the atomization component 12.

[0084] The atomization assembly 12 includes an atomization tube 121, a liquid guide part 122 and a heating part 123. The atomization tube 121 is inserted into the atomization airway 1121, and the liquid guide part 122 is installed in the atomization tube 121. The liquid guide part 122 is usually a hollow columnar structure with openings at both ends. The liquid guide part 122 can also be made of cotton or fiber material. The heating part 123 is installed in the internal cavity of the liquid guide part 122. The heating part 123 is usually a mesh heating wire structure, which can realize circumferential heating function. The airflow sensor 30 is electrically connected to the heating element 123. In response to the change in the air pressure signal of the atomizing airway 1121, the airflow sensor 30 outputs an electrical signal to the heating element 123 to start the operation of the heating element 123, thereby heating the atomizing matrix. After the external air enters the atomizing airway 1121 through the air inlet hole 22 and the air inlet cavity 21, there is a certain temperature difference between the temperature of the external air and the temperature of the atomizing matrix heated by the heating element 123, which can cause the heated atomizing matrix to condense to form liquid particles, thereby generating an aerosol.

[0085] Continue to see Figure 1 As shown, the liquid storage assembly 11 also includes a bottom cover 113, which is usually provided with an atomizer seat 1131. A slot 1132 is provided in the atomizer seat 1131. The slot 1132 is an axially through hollow structure. The atomizer tube 121 is inserted into the slot 1132 of the atomizer seat 1131, and the bottom cover 113 is installed on the side of the liquid storage tank 111 where the opening 1111 is provided to close the opening 1111, thereby forming a cavity structure for placing the liquid storage component 112 through the bottom cover 113 and the liquid storage tank 111.

[0086] The bottom shell 20 and the bottom cover 113 are connected to each other, so that the bottom shell 20 and the bottom cover 113 enclose the air inlet cavity 21. Since the slot 1132 for inserting the atomizer tube 121 is an axially through hollow structure, the atomizer tube 121 and the air inlet cavity 21 can be kept in a connected state.

[0087] In this embodiment, the atomizer 10 further includes a housing 14 , the liquid storage assembly 11 and the atomization assembly 12 are both installed inside the housing 14 , the bottom end of the housing 14 is an open structure, and the bottom shell 20 is connected to the open structure at the bottom end of the housing 14 .

[0088] In one embodiment of the present application, the atomizer 10 further includes a nozzle 13, in which a nozzle channel 131 is provided. The nozzle 13 is mounted on a side of the liquid storage tank 111 where a conducting hole 1112 is provided, and the nozzle channel 131 is connected to the conducting hole 1112. When in use, the user inhales through the nozzle 13, so that a negative pressure is generated in the nozzle channel 131, the atomizing airway 1121, and the air inlet chamber 21. The airflow sensor 30 senses the airflow change in response to the air pressure change and outputs an electrical signal to the heater 123 in the atomizer 10 of the atomizer device 100 to trigger the heater 123 to work and heat the atomizing matrix. The external gas causes the heated atomizing matrix to condense to form liquid particles, thereby generating an aerosol. The generated aerosol is output to the outside of the atomizing device 100 through the nozzle channel 131.

[0089] During the aerosol delivery process, due to the influence of the transmission distance, the aerosol will condense and produce condensate due to heat exchange with the shell of the suction nozzle 13. In order to prevent the condensate from flowing back into the atomization airway 1121 and affecting the taste of the aerosol, in this embodiment, a liquid absorption member 132 is further provided between the suction nozzle channel 131 of the suction nozzle 13 and the conducting hole 1112 of the liquid storage tank 111 to absorb the condensate.

[0090] In some embodiments, a liquid guide port is usually further provided on the atomizing tube 121, and part of the liquid guide member 122 extends to the outside of the atomizing tube 121 through the liquid guide port. After the atomizing tube 121 is installed inside the atomizing air channel 1121, the part of the liquid guide member 122 extending to the outside of the atomizing tube 121 through the liquid guide port can be made to fully contact the liquid storage member 112 to achieve conduction of the atomizing matrix. The heating member 123 can heat the atomizing matrix to generate an aerosol, and the generated aerosol is output to the outside of the atomizer through the atomizing tube 121, the atomizing air channel 1121, and the conducting hole 1112.

[0091] See also Figure 1-Figure 4 As shown, the atomization device provided in this embodiment also includes a second circuit board 53' and an adjustment component 50. The second circuit board 53' is provided with a power control key 51. The power control key 51 can move relative to the second circuit board 53' to adjust the power of the atomization device. The power control key 51 is connected to the adjustment component 50.

[0092] In this embodiment, the atomizer 10 is provided with at least two air inlet holes 22 communicating with the air inlet chamber 21. The adjustment assembly 50 covers the at least two air inlet holes 22. The adjustment assembly 50 can move relative to the second circuit board 53' to change the communication area of the at least two air inlet holes 22 and thereby drive the movement of the power control button 51. In other words, the movement of the adjustment assembly 50 relative to the second circuit board 53' simultaneously drives the movement of the power control button 51. That is, the adjustment assembly 50 and the power control button 51 are in a linked relationship.

[0093] In a specific embodiment, the power control key 51 is electrically connected to the heating element 123 of the atomizer 10. When the adjustment component 50 moves relative to the second circuit board 53' to change the communication area of at least two air adjustment holes 22, the air intake volume of the atomization device can be changed, and the power control key 51 can move synchronously with the adjustment component 50 relative to the second circuit board 53' to adjust the power of the heating element 123 in the atomizer 10, that is, adjust the heating power of the atomizer 10, thereby changing the temperature at which the atomizer 10 heats the atomized substrate.

[0094] More specifically, the adjustment component 50 can be movably installed on the bottom shell 20 to adjust the size of the air inlet hole 22. Since external gas enters the air inlet cavity 21 through the air inlet hole 22, the amount of air entering the air inlet cavity 21 through the air inlet hole 22 can be changed by changing the size of the air inlet hole 22.

[0095] In this embodiment, the adjustment component 50 includes an air regulating valve 52, which is movably mounted on the bottom shell 20. The power control button 51 is linked to the air regulating valve 52. The movement of the air regulating valve 52 relative to the second circuit board 53' changes the communication area of the at least two air inlet holes 22, thereby changing the suction resistance when drawing through the mouthpiece 13. The power control button 51 can move relative to the second circuit board 53' in conjunction with the air regulating valve 52 to adjust the power of the atomizer 10. Specifically, the power control button 51 changes the power size by adjusting the voltage to the atomizer 10.

[0096] The aerosol generated by the atomizer 10 through heating has a certain amount of heat, which can be heat-exchanged with the external air entering the atomizing airway 1121 to form the atomized matrix into particles, thereby generating an aerosol.

[0097] In this embodiment, the air regulating valve 52 can adjust the air intake volume by partially blocking at least two air intake holes 22 , or completely blocking at least two air intake holes 22 .

[0098] Of course, in other embodiments, the air intake hole 22 is a complete hole, and the air regulating valve 52 adjusts the air intake volume by partially blocking it.

[0099] In one embodiment of the present application, Figure 5 As shown, the second circuit board 53' has a power adjustment circuit electrically connected to the power control key 51, which can adjust the heating power of the heating element 123 through the power adjustment circuit. The second circuit board 53' is disposed inside the bottom housing 20, and the power control key 51 is mounted on the circuit board 42.

[0100] In the present application, the first circuit board 53 and the second circuit board 53' can be independent circuit board structures or integrated into the same circuit board. When independent, the two circuit boards can be installed on the same plane or separately. In a preferred embodiment, the two independent circuit boards are installed on the same plane to save installation space.

[0101] In this embodiment, the first circuit board 53 and the second circuit board 53 ′ are integrated into the same circuit board as an example for description.

[0102] The heating element 123 needs to work under the action of electric energy to generate heat, such as Figure 2 and Figure 3 As shown, the atomization device provided in the present application also includes an energy supply unit 60, which is arranged inside the bottom shell 20 and above the first circuit board 53 and the second circuit board 53'. The energy supply unit 60 is electrically connected to the heating element 123. When the airflow sensor 30 generates a trigger signal to trigger the heating element 123 to work when the airflow changes, the connection between the energy supply unit 60 and the heating element 123 can be connected to provide electrical energy to the heating element 123 through the energy supply unit 60.

[0103] The energy supply unit 60 is generally a rechargeable structure, for example, a lithium battery. Therefore, the atomization device provided in the present application also includes a charging interface 15, which can be electrically connected to the input end of the energy supply unit 60. The energy supply unit 60 can be connected to an external power source through the charging interface 15 to replenish electrical energy to the energy supply unit 60 through the power source, thereby improving the portability and service life of the atomization device.

[0104] The charging port 15 is typically installed at the bottom of the atomizer product to ensure the aesthetics of the overall structure of the atomizer product. The bottom of the product is the bottom of the bottom shell 20 in this application. In a preferred embodiment, the charging port 15 is installed in the accommodating cavity 42 of the sensor bracket 40. At the same time, to save installation space and simplify the product structure, the installation opening of the charging port 15 on the bottom shell 20 is used as the communication hole 23, and the accommodating cavity 42 of the charging port 15 is provided on the sensor bracket 40.

[0105] In this embodiment, one end opening of the accommodating chamber 42 is connected to the communicating hole 23, and one end opening of the accommodating chamber 42 connected to the communicating hole 23 faces the communicating hole 23. In a preferred embodiment, the opening is located at the position of the communicating hole 23, and the other end of the accommodating chamber 42 is closed by a circuit board. The accommodating chamber 42 is formed into a cavity structure for installing the charging interface 15, that is, the charging interface 15 can be installed in the accommodating chamber 42, and the second air duct 44 is arranged between the mounting chamber 41 and the accommodating chamber 42. After the airflow sensor 30 is installed in the mounting chamber 41, the second sensing side 32 of the airflow sensor 30 is located on the side where the second air duct 44 is set, thereby keeping the second sensing side 32 of the airflow sensor 30 connected to the external atmospheric pressure through the second air duct 44 and the communicating hole 23.

[0106] When the external air enters the air inlet cavity 21 through the air inlet hole 22 under the action of the user's suction nozzle 13, in order to allow the air flow to flow into the air inlet cavity 21, Figure 2-Figure 4 As shown, the atomizing device provided in this embodiment further includes a flow guide 70, which is disposed inside the bottom housing 20, specifically mounted on the second circuit board 53' and located above the air inlet 22. The flow guide 70 is provided with a flow guide groove 71, the notch of which faces the air inlet 22, and a flow guide slope 72 is provided at the bottom of the flow guide groove 71 in an inclined manner. The flow guide slope 71 is used to guide the airflow entering through the air inlet 22 toward the air inlet cavity 21.

[0107] In this embodiment, when the size of the air inlet hole 22 is adjusted by the air regulating valve 52, the air regulating valve 52 slides in a sliding manner, and the size of the air inlet hole 22 is adjusted by blocking the air inlet hole 22 during the sliding process. In order to ensure the sealing effect of blocking the air inlet hole 22, the adjustment component 50 also includes a second sealing portion 54, and the second sealing portion 54 is installed on the side of the air regulating valve 52 facing the bottom shell 20, so that in the process of moving the air regulating valve 52, the air inlet hole 22 is blocked by the second sealing portion 54, thereby adjusting the size of the air inlet hole 22.

[0108] like Figure 4 As shown, a slide groove 24 is also provided on the bottom shell 20, and the air regulating valve 52 can be slidably installed in the slide groove 24. The air regulating valve 52 can slide along the slide groove 24 toward or away from the air inlet 22 to adjust the size of the air inlet 22 by blocking the air inlet 22.

[0109] To sum up, in the sensing component and atomization device provided by the present application, the charging interface is installed through the installation cavity provided by the sensor bracket, which not only utilizes the characteristic that the charging interface is connected to the outside world, but also provides a first air duct on one side of the sensor bracket, the first air duct connects the first sensing side and the accommodating cavity of the airflow sensor, and meets the requirement that the first sensing side needs to be connected to the outside atmosphere. At the same time, a second sensing side connected to the airflow sensor and a second air duct connected to the atomization air duct are provided on the other side of the sensor bracket. Such a setting simplifies the detection air duct design of the airflow sensor and improves the sensitivity of the airflow sensor; at the same time, it can also reduce the number of holes opened on the outer shell of the atomization device, reduce the processing requirements of the process, and improve the aesthetics of the overall structure of the product; and also combined with the spatial position of the charging interface, the airflow sensor and the charging interface are set on the same module to optimize the internal space design of the atomization device.
