As shown in FIGS. 1 and 2 , one embodiment of the present application provides an electronic atomization device 1000 for atomizing an aerosol-generating substrate to generate aerosol for human inhalation. The electronic atomization device 1000 includes an atomization component 100 and a power supply component 200. The atomization component 100 is coupled to one end of the power supply component 200 and is electrically connected to the power supply component 200. The atomization component 100 can be heated by the electric energy of the power supply component 200. Nebulized aerosol-generating matrix.

Specifically, the atomization assembly 100 includes an atomization housing 120 and an atomization core 140 . Among them, the atomization housing 120 has a shell-like structure with one end open. The atomization core 140 is accommodated in the open end of the atomization housing 120. The other end of the atomization housing 120 is provided with an exhaust channel 160 and a peripheral To the liquid storage chamber 180 surrounding the exhaust channel 160, one end of the exhaust channel 160 is connected to the atomization core 140, and the other end of the exhaust channel 160 passes through the closed end of the atomization housing 120 and is connected to the external environment. The liquid storage chamber 180 is used to store the aerosol-generating matrix. The aerosol-generating matrix in the liquid storage chamber 11 can flow into the atomizing core 140 and be heated and atomized by the atomizing core 140 . The aerosol generated by atomization can pass through the exhaust channel 160 The liquid flows out of the atomization housing 120 for the user to inhale.

The power supply component 200 is coupled to one end of the atomization component 100 with the atomization core 140. The power supply component 200 is provided with a battery core 230, a microphone 240 and a charging board 250. The battery core 230 and the atomization core 140 are electrically connected to form a mist. The battery core 140 supplies power, the charging board 250 is used to charge the battery core 230 from an external power source, and the microphone 240 is used to sense the air flow in the power supply assembly 200 to control the working status of the electronic atomization device 100 .

As mentioned in the background art, electric control components such as batteries, microphones, and charging boards in existing power components are all housed in the same chamber. The charging boards, batteries, and microphones are arranged sequentially along the axial direction of the power supply component. There is no separation between them. When suctioning, there is air flow through these electronic control components, and the condensate generated when the return air flow is cold will adhere to the surface of the electronic control components, thereby increasing the risk of short circuits.

In order to solve the above technical problems, the power supply assembly 200 of the present application is provided with a battery core cavity 214 and an electric control cavity 215 that are independent of each other and an air flow channel that is independent of the electric control cavity 215. The air flow channel extends from the power supply assembly along the axial direction of the power supply assembly 200. One end of 200 extends to the other end of the power supply assembly 200 through the battery cavity 214. The battery cavity 214 is used to accommodate the battery core 230, and the electronic control cavity 215 is used to accommodate electronic control components such as the microphone 240 or the charging board 250. Among them, "independent" means that there is a clear separation between the chambers, which has a certain blocking effect on the air flow and prevents the air flow from flowing smoothly between the chambers, but it does not mean that the chambers are completely sealed and completely There is no airflow.

Since the air flow channel and the electric control cavity 215 are set independently, the air flow flowing through the air flow channel will basically not pass through the electric control cavity 215, thereby effectively preventing the condensate generated by the cold air flow from adsorbing on the electric control components in the electric control cavity 215, which significantly improves the efficiency of the air flow channel. Reduces the risk of electrical short circuits.

Please continue to refer to FIGS. 1 and 2 . The power supply assembly 200 includes a housing 210 and a mounting bracket 260 . The housing 210 has a receiving cavity. The mounting bracket 260 is received in the housing 210 and is used to separate the receiving cavity to form a cell cavity 214 and an electronic control unit. The cavity 215 serves to support and limit the atomization core 140 of the atomization assembly 100 .

Specifically, the shell 210 is generally a hollow columnar structure, including a shell bottom wall and a shell side wall extending in the same direction from the edge of the shell bottom wall.

In the following embodiments, the central axis direction of the housing 210 extends along the Z direction in FIG. 1 , the radial direction of the housing 210 is a direction perpendicular to the Z direction, and the circumferential direction of the housing 210 is a direction surrounding the Z direction.

Please refer to Figures 3 to 5. As shown in Figures 3 to 5, the mounting bracket 260 is a one-piece shell-like structure. The axial direction of the mounting bracket 260 is parallel to the axial direction of the housing 210. The battery cavity 214 is formed in the middle of the mounting bracket 260. The electronic control The cavity 215 is formed at one end of the mounting bracket 260 close to the air inlet end of the air flow channel. The length direction of the mounting bracket 260 is the first direction (ie, the X direction in FIG. 4 ), and the width direction of the mounting bracket 260 is the second direction (ie, the Y direction in FIG. 4 ).

In the following embodiments, the end of the mounting bracket 260 away from the atomization core 140 forms a first axial portion 261 , and the end of the mounting bracket 260 close to the atomization core 140 forms a second axial portion 263 , and the mounting bracket 260 is connected to Parts of the first axial portion 261 and the second axial portion 263 form an intermediate connection portion 265 .

Specifically, both sides of the first axial portion 261 in the second direction are respectively formed with inwardly concave grooves. The groove walls and the cavity walls of the accommodation cavity jointly define two electronic control cavities 215. The two electronic control cavities 215 are formed. The cavities 215 are spaced apart in the second direction. One of the electrical control chambers 215 has a rectangular cross-section perpendicular to the second direction for accommodating the charging plate 250 , and the other electrical control cavity 215 has a circular cross-section perpendicular to the second direction. Shaped to accommodate the microphone 240. The top wall on one side of the second axial portion 263 away from the first axial end 261 is recessed inward to form a groove for accommodating the atomizing core 140 .

The middle connection part 265 is located on the side of the mounting bracket 260 with the charging plate 250 in the second direction. The middle connection part 265 extends in a curved manner around the central axis of the installation bracket 260 , and the cross section of the middle connection part 265 perpendicular to the axial direction is generally semicircular. Arc-shaped, one end of the middle connecting portion 265 is connected to the edge of one end surface of the first axial portion 261 toward the second axial portion 263, and the other end of the middle connecting portion 265 is connected to the second axial portion 263 toward the first axial direction. The edge of one end surface of the portion 261.

In this way, the middle connection portion 265, the first axial portion 261, the second axial portion 263 and the housing 210 jointly define the battery core cavity 214, and the inner wall of the middle connection portion 265 forms one side wall of the battery core cavity 214. The inner wall of the housing 210 forms the other side wall of the battery cavity 214 . One end surface of the first axial portion 261 facing the second axial portion 263 forms the bottom wall of the battery cavity 214 . The second axial portion 263 One end face facing the first axial end forms the top wall of the cell cavity 214 . When the battery core 230 is received in the battery cavity 214, one radial side of the battery core 230 is shielded by the intermediate connection portion 265, and the other radial side of the battery core 230 is exposed to the outside of the intermediate connection portion 265. The battery core 230 The two end surfaces of are respectively shielded by the bottom wall and the top wall of the cell cavity 214.

It can be understood that the structure of the mounting bracket 260 is not limited to this. The mounting bracket 260 can be a one-piece structure, or can be assembled from multiple components. The shape of the mounting bracket 260 can be based on the shapes of the housing 210, the battery core 230 and each electronic control component. Designed to meet different requirements. In some other embodiments, each chamber may not be formed by the mounting bracket 260 , and the location of the electrical control chamber 215 may not be limited to the end of the mounting bracket 260 away from the atomizing core 140 but at other locations. The number of electrical control chambers 215 It is not limited to two, and can be set according to the number and shape of electronic control components to meet different requirements.

The mounting bracket 260 has an air inlet hole 2612 in the first axial portion 261 away from the atomizing core 140. The air inlet hole 2612 is used to form the air inlet end of the air flow channel. The bottom wall of the housing 210 has a corresponding connected air inlet hole. 2612 through hole. Specifically, the air inlet hole 2612 is formed at the center of the first axial part 261 and is located between the two electronic control chambers 215 . One end of the air inlet hole 2612 is connected to an end surface of the first axial part 261 away from the intermediate connection part 265 , the other end of the air inlet hole 2612 passes between the two electronic control cavities 215 and extends zigzag to one end surface of the first axial part 261 connected to the intermediate connecting part 265 . In this way, one end of the air inlet hole 2612 is connected to the external environment through the through hole on the housing 210, and the other end of the air inlet hole 2612 is connected to the battery core cavity 214. The air in the external environment can enter the battery core cavity 214 through the air inlet hole 2612.

A first air outlet hole 2652 for forming an air flow channel is penetrated through the side wall of one end of the middle connecting portion 265 of the mounting bracket 260 close to the air inlet hole 2612. The first air outlet hole 2652 connects the battery core cavity 214 and the outer wall of the mounting bracket 260, and The first air outlet hole 2652 is located at the middle position of the mounting bracket 260 in the first direction. In this way, the airflow in the battery cavity 214 can be concentrated and flow out of the battery cavity 214 through the first air outlet 2652 without flowing to other areas in the battery cavity 214 .

Furthermore, the end surface of the battery core 230 accommodated in the battery core cavity 214 close to the air inlet 2612 is a non-flat surface. There is a gap connecting the air inlet hole 2612 and the first air outlet hole 2652 between the end surfaces).

In this way, after the airflow flowing in from the air inlet hole 2612 passes through the gap between one end surface of the battery core 230 and the cavity wall of the battery core cavity 214, it can flow out of the battery core cavity 214 from the first air outlet hole 2652. Since the air flow channel avoids most areas of the battery core cavity 214, and during the suction process, the end of the mounting bracket 260 away from the atomizing core 140 is at a lower position in the direction of gravity, so that the condensate will not flow to the battery core. 230 in other positions so as not to cause a short circuit in the circuit.

Further, the outer wall of the middle connecting portion 265 of the mounting bracket 260 is provided with a communication groove 2654 for forming an air flow channel. The communication groove 2654 is located at the middle position of the installation bracket 260 in the first direction. One end of the communication groove 2654 is connected to the first outlet. The other ends of the air hole 2652 and the communication groove 2654 extend along the axial direction of the mounting bracket 260 to the second axial portion 263 of the mounting bracket 260 close to the atomization core 140 . In this way, the airflow flowing out from the first air outlet hole 2652 flows to the atomizing core 140 through the communication groove 2654 without spreading to various areas of the external space of the mounting bracket 260 .

The second axial portion 263 of the end of the mounting bracket 260 close to the atomization core 140 is connected to the middle connecting portion 265 and has a guide groove 2632. There are two guide plates 2634 in the guide groove 2632. The flow plates 2634 are spaced apart along the first direction to form flow guide channels 2636 connected to the communication slot 2654. The flow guide channels 2636 are located downstream of the communication slot 2654 and are used to move the gas in the communication slot 2654 closer to the axis of the mounting bracket 260. direction guidance.

The second axial portion 263 has a second air outlet hole 2638 for forming an air flow channel. The second air outlet hole 2638 is located downstream of the flow guide channel 2636. The central axis of the second air outlet hole 2638 extends along the axial direction of the mounting bracket 260. The flow channel 2636 and the atomizing core 140 are connected through the second air outlet hole 2638, which is used to allow the gas in the flow guide channel 2636 to flow out of the mounting bracket 260 and enter the atomizing core 140. In this way, the airflow flowing out of the guide channel 2636 can enter the atomizing core 140 through the second air outlet hole 2638, and then carry the aerosol generated by heating the atomized aerosol-generating substrate of the atomizing core 140 into the air outlet channel 212.

In some embodiments, in order to prevent the condensate condensed by the return airflow from flowing into the battery cavity 214 or the electronic control cavity 215 , a liquid storage tank 2656 is also provided on the outer wall of the middle connecting portion 265 of the mounting bracket 260 . As a preferred embodiment, two sets of liquid storage tanks 2656 are provided on the outer wall of the mounting bracket 260. The two groups of liquid storage tanks 2656 are respectively provided on both sides of the communication groove 2654 along the first direction. Each group of liquid storage tanks 2656 includes There are multiple liquid storage tanks 2656. All the liquid storage tanks 2656 in the same group are arranged at intervals along the axial direction of the mounting bracket 260. Each liquid storage tank 2656 extends along the circumferential direction of the mounting bracket 260 to form an arc. It can be understood that the number, shape and location of the liquid storage tanks 2656 are not limited thereto, and can be set as needed to meet different requirements.

In some embodiments, as shown in FIG. 2 , the power supply assembly 200 further includes a liquid absorbing member 270 , which is embedded in the guide groove 2632 in the second axial part 263 and along the axial direction of the mounting bracket 260 Toward diversion channel 2636. In this way, the liquid suction member 270 is located between the flow guide channel 2636 and the second air inlet hole 2612, and the condensed water generated by the air flow flowing through the second air inlet hole 2612 and the flow guide channel 2636 can be absorbed by the liquid suction member 270, thereby preventing condensation. The liquid adheres to the battery core 230 or other electronic control components. It can be understood that the material used to form the liquid-absorbent member 270 is not limited. In one embodiment, the liquid-absorbent member 270 is made of porous material (such as liquid-absorbent cotton), which has good absorption effect.

Please refer to Figure 6. In some embodiments, the first axial portion 261 is provided with a starting channel 2614. One end of the starting channel 2614 is connected to the inner surface of the air inlet 2612, and the other end of the starting channel 2614 extends along the radial direction of the housing 210. to the electronic control cavity 215 for accommodating the microphone 240, thus connecting the air inlet 2612 and the sensing surface of the microphone 240. The side surface of the microphone 240 facing away from the activation channel 2614 is connected to the outside atmosphere. When the user inhales the electronic atomization device 100, air flow is generated in the activation channel 2614 connected to the air inlet 2612, causing a pressure difference to be formed on both sides of the microphone 240. The microphone 240 then controls the opening of the electronic atomization device 100. The aerosol-generating matrix is used for users to inhale.

It can be understood that since the microphone 240 is disposed on the first axial portion 261 of the mounting bracket 260, the side surface of the microphone 240 facing away from the startup channel 2614 can better communicate with the outside atmosphere, making the startup of the microphone 240 easier. sensitive.

In order to prevent the electronic atomization device 100 from leaking during transportation, the first sealing plug 300 can be inserted into the air inlet 2612, and the second sealing plug 400 can be inserted into the air outlet end of the exhaust channel 160, so that the housing 210 A closed environment is formed inside.

During the research process, the applicant found that when the sensing surface of the microphone 240 is connected to the sealed environment formed in the housing 210, since the other surface of the microphone 240 facing away from the sensing surface is connected to the outside atmosphere, the two sides of the microphone 240 A pressure difference will occur on both sides, causing the electronic atomizer 100 to start abnormally.

In order to solve the above problem, the air inlet hole 2612 of the present application has a sealing surface located downstream of the starting channel 2614. One end of the first sealing plug 300 inserted in the air inlet hole 2612 has a sealing portion 281 that sealingly cooperates with the sealing surface. When the first sealing plug 300 is inserted into the air inlet 2612, the first sealing plug 300 sealingly fits with the sealing surface of the air inlet 2612 through the sealing portion 281, and the activation channel 2614 is located away from the first sealing plug 300 and the first air outlet. 2652, so the activation channel 2614 is connected to the outside atmosphere through the gap between the first sealing plug 300 and the air inlet 2612, so that the microphone 240 is located outside the closed environment formed in the housing 210 and connected to the outside atmosphere. The pressure on the sensing surface of the microphone 240 and the other surface facing away from the sensing surface are always consistent, thereby preventing the electronic atomization device 100 from abnormally starting due to pressure differences sensed by the microphone 240 due to transportation or changes in the external environment. Specifically, in one embodiment, the inner surface of one end of the air inlet hole 2612 close to the cell cavity 214 forms a sealing surface, and the outer diameter of the sealing portion 281 is larger than the inner diameter of the portion of the air inlet hole 2612 that forms the sealing surface, so that it is consistent with the air inlet hole 2612 The sealing surface sealing fit.

The above-mentioned electronic atomization device 100 divides the internal space of the casing 210 into an independently arranged battery core cavity 214 and at least one electronic control cavity 215. Since the air flow channel in the casing 210 is arranged independently of the electric control cavity 215 and avoids the battery core, Most areas of the cavity 214, therefore the condensate formed by the return air flow in the air flow channel will not adhere to the electrical control components located in the electrical control cavity 215, significantly reducing the risk of circuit short circuit. Moreover, after the first sealing plug 300 and the second sealing plug 400 are plugged in, the pressure on both sides of the microphone 240 remains consistent. Therefore, abnormal startup of the electronic atomization device 100 during transportation or environmental changes can be avoided.

The technical features of the above-described embodiments can be combined in any way. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described.
