As shown in fig. 1 and 2, one embodiment of the present application provides an electronic atomizing device 1000 for atomizing an aerosol-generating substrate to produce an aerosol for human consumption. The electronic atomizer 1000 includes an atomizer assembly 100 and a power module 200, the atomizer assembly 100 is coupled to an end of the power module 200 and electrically connected to the power module 200, and the atomizer assembly 100 is capable of heating an aerosol-generating substrate under the electrical energy of the power module 200.

Specifically, the atomization assembly 100 includes an atomization housing 120 and an atomization core 140. The atomizing housing 120 is a housing-shaped structure with an opening at one end, the atomizing core 140 is accommodated in the opening end of the atomizing housing 120, the other end of the atomizing housing 120 is provided with an exhaust channel 160 and a liquid storage cavity 180 circumferentially surrounding the exhaust channel 160, one end of the exhaust channel 160 is communicated with the atomizing core 140, and the other end of the exhaust channel 160 penetrates through the closed end of the atomizing housing 120 to be communicated with the external environment. Reservoir chamber 180 is configured to store an aerosol-generating substrate, and the aerosol-generating substrate in reservoir chamber 11 can flow into atomizing core 140 and be heated and atomized by atomizing core 140, and the aerosol generated by atomization can flow out of atomizing housing 120 through air-vent channel 160 for a user to inhale.

The power supply module 200 is connected to the end of the atomizing module 100, where the atomizing core 140 is disposed, the power supply module 200 is provided with an electrical core 230, a charging pad 240 and a charging pad 250, the electrical core 230 is electrically connected to the atomizing core 140 to supply power to the atomizing core 140, the charging pad 250 is used for charging the electrical core 230 by an external power supply, and the charging pad 240 is used for inducing the airflow in the power supply module 200 to flow so as to control the operating state of the electronic atomizing device 100.

As described in the background art, the electric control elements such as the battery core, the microphone and the charging pad in the conventional power supply module are all accommodated in the same cavity, the charging pad, the battery core and the microphone are sequentially arranged along the axial direction of the power supply module and are not separated from each other, when suction is performed, airflow flows through the electric control elements, and condensate generated by cooling of backflow airflow is attached to the surfaces of the electric control elements, so that the risk of short circuit of a circuit is increased.

In order to solve the above technical problem, in the power supply module 200 of the present application, a cell cavity 214 and an electrical control cavity 215 that are independent from each other and an airflow channel that is independent from the electrical control cavity 215 are provided, the airflow channel extends from one end of the power supply module 200 to the other end of the power supply module 200 through the cell cavity 214 along an axial direction of the power supply module 200, the cell cavity 214 is configured to accommodate a cell 230, and the electrical control cavity 215 is configured to accommodate electrical control elements such as a microphone 240 or a charging board 250. The term "independent" means that there is a significant separation between the chambers, so as to block the airflow and prevent the airflow from flowing smoothly between the chambers, but does not mean that the chambers are completely sealed and there is no airflow flowing at all.

Because the air flow channel and the electric control cavity 215 are independently arranged, the air flow passing through the air flow channel basically cannot pass through the electric control cavity 215, so that condensate generated by the air flow when the air flow is cooled is effectively prevented from being adsorbed on an electric control element in the electric control cavity 215, and the risk of short circuit of a circuit is obviously reduced.

With continued reference to fig. 1 and 2, the power module 200 includes a housing 210 and a mounting bracket 260, the housing 210 has a receiving cavity, and the mounting bracket 260 is received in the housing 210 to divide the receiving cavity into an electrical core cavity 214 and an electrical control cavity 215, and to support and limit the atomizing core 140 of the atomizing assembly 100.

Specifically, the housing 210 is a hollow cylindrical structure, and includes a housing bottom wall and a housing side wall extending from an edge of the housing bottom wall toward the same direction, and the housing side wall circumferentially surrounds the housing bottom wall to form an accommodating cavity with an opening at one end.

It is understood that the shape and configuration of the housing 210 are not limited and can be configured as desired to meet different requirements. In the following embodiments, the central axis direction of the housing 210 extends in 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 around the Z direction.

As shown in fig. 3 to 5, the mounting bracket 260 is an integrally formed shell-shaped structure, the axial direction of the mounting bracket 260 is parallel to the axial direction of the housing 210, the core cavity 214 is formed in the middle of the mounting bracket 260, and the electronic control cavity 215 is formed at one end of the mounting bracket 260 close to the air inlet end of the airflow channel. The length direction of the mounting bracket 260 is a first direction (i.e., X direction in fig. 4), and the width direction of the mounting bracket 260 is a second direction (i.e., Y direction in fig. 4).

In the following embodiments, one end of the mounting bracket 260 away from the atomizing core 140 forms a first axial portion 261, one end of the mounting bracket 260 close to the atomizing core 140 forms a second axial portion 263, and a portion of the mounting bracket 260 connecting the first axial portion 261 and the second axial portion 263 forms an intermediate connecting portion 265.

Specifically, two sides of the first axial portion 261 in the second direction form inward concave grooves respectively, the groove wall and the cavity wall of the accommodating cavity define together to form two electronic control cavities 215, the two electronic control cavities 215 are arranged at intervals in the second direction, a cross section of one of the electronic control cavities 215 perpendicular to the second direction is rectangular for accommodating the charging board 250, and a cross section of the other electronic control cavity 215 perpendicular to the second direction is circular for accommodating the microphone 240. A side top wall of the second axial portion 263 facing away from the first axial end 261 is recessed inward to form a recess for accommodating the atomizing core 140.

The intermediate connecting portion 265 is located on the side of the mounting bracket 260 on which the charging plate 250 is provided in the second direction, the intermediate connecting portion 265 extends in a curved manner around the central axis of the mounting bracket 260, and a cross section of the intermediate connecting portion 265 perpendicular to the axial direction is substantially a semicircular arc shape, one end of the intermediate connecting portion 265 is connected to an edge of an end surface of the first axial portion 261 facing the one end of the second axial portion 263, and the other end of the intermediate connecting portion 265 is connected to an edge of an end surface of the second axial portion 263 facing the one end of the first axial portion 261.

In this way, the intermediate connecting portion 265, the first axial portion 261, the second axial portion 263 and the outer shell 210 define and form the core cavity 214, an inner side wall of the intermediate connecting portion 265 forms a side cavity side wall of the core cavity 214, an inner side wall of the outer shell 210 forms another side cavity side wall of the core cavity 214, an end surface of the first axial portion 261 facing the second axial portion 263 forms a cavity bottom wall of the core cavity 214, and an end surface of the second axial portion 263 facing the first axial end forms a cavity top wall of the core cavity 214. When the battery cell 230 is accommodated in the battery cell cavity 214, one radial side of the battery cell 230 is shielded by the intermediate connection portion 265, the other radial side of the battery cell 230 is exposed outside the intermediate connection portion 265, and end faces of two ends of the battery cell 230 are respectively shielded by a cavity bottom wall and a cavity top wall of the battery cell cavity 214.

It is understood that the configuration of the mounting bracket 260 is not limited thereto, the mounting bracket 260 may be an integrally formed structure, and may also be assembled by a plurality of components, and the shape of the mounting bracket 260 may be designed according to the shapes of the housing 210, the battery cell 230, and the various electric control elements to meet different requirements. In other embodiments, the chambers may not be formed by the mounting bracket 260, the position of the electronic control chamber 215 may not be limited to the end of the mounting bracket 260 away from the atomizing core 140, and the number of the electronic control chambers 215 is not limited to two, and may be set according to the number and shape of the electronic control elements to meet different requirements.

The first axial portion 261 of the mounting bracket 260, which is far away from the atomizing core 140, is opened with an air inlet hole 2612, the air inlet hole 2612 is used for forming an air inlet end of an air flow channel, and the bottom wall of the housing 210 is correspondingly opened with a through hole communicated with the air inlet hole 2612. Specifically, the air inlet hole 2612 is formed in the center of the first axial portion 261 and located between the two electronic control chambers 215, one end of the air inlet hole 2612 communicates with one end face of the first axial portion 261 far away from the intermediate connecting portion 265, and the other end of the air inlet hole 2612 passes through the space between the two electronic control chambers 215 and extends to the end face of the first axial portion 261 connected to the intermediate connecting portion 265 in a zigzag manner. Thus, 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 electric core chamber 214, so that the air in the external environment can enter the electric core chamber 214 through the air inlet hole 2612.

A first air outlet hole 2652 for forming an air flow channel is formed through a side wall of one end of the middle connecting portion 265 of the mounting bracket 260, which is close to the air inlet hole 2612, the first air outlet hole 2652 connects the core cavity 214 and an outer side wall of the mounting bracket 260, and the first air outlet hole 2652 is located at a middle position of the mounting bracket 260 in the first direction. In this manner, the airflow in the core cavity 214 may be concentrated out of the core cavity 214 through the first exit aperture 2652 and not to other areas in the core cavity 214.

Further, an end surface of the electric core 230 accommodated in the electric core cavity 214, which is close to the air inlet hole 2612, is a non-flat surface, so that a gap for communicating the air inlet hole 2612 and the first air outlet hole 2652 exists between the end surface and a cavity wall of the electric core cavity 214 (i.e., an end surface of the first axial portion 261 facing the electric core cavity 214).

In this way, the airflow flowing in from the air inlet hole 2612 can flow out of the cell cavity 214 from the first air outlet hole 2652 after passing through the gap between the end surface of the cell 230 and the cavity wall of the cell cavity 214. Since the airflow channel avoids most of the area of the cell cavity 214, and the end of the mounting bracket 260 remote from the atomizing core 140 is at a lower position in the direction of gravity during the pumping process, the condensate does not flow to other positions of the cell 230, and thus, the short circuit is not caused.

Further, a communication groove 2654 for forming an airflow channel is opened in an outer side wall of the intermediate connecting portion 265 of the mounting bracket 260, the communication groove 2654 is located at an intermediate position of the mounting bracket 260 in the first direction, one end of the communication groove 2654 communicates with the first air outlet 2652, and the other end of the communication groove 2654 extends to the second axial portion 263 of the mounting bracket 260 close to the atomizing core 140 along the axial direction of the mounting bracket 260. In this manner, the airflow flowing out of the first outlet hole 2652 flows toward the atomizing core 140 through the communication groove 2654 without being diffused to various regions of the external space of the mounting bracket 260.

A flow guide groove 2632 is formed in one side, connected to the intermediate connecting portion 265, of the second axial portion 263 at one end of the mounting bracket 260 close to the atomizing core 140, two flow guide plates 2634 are arranged in the flow guide groove 2632, the two flow guide plates 2634 are arranged at intervals along the first direction to form a flow guide channel 2636 communicated with the communicating groove 2654, and the flow guide channel 2636 is located at the downstream of the communicating groove 2654 and used for guiding the gas in the communicating groove 2654 to a direction close to the axis of the mounting bracket 260.

The second axial portion 263 defines a second air outlet 2638 for forming an air flow channel, the second air outlet 2638 is located downstream of the flow guide channel 2636, a central axis of the second air outlet 2638 extends along the axial direction of the mounting bracket 260, the flow guide channel 2636 is communicated with the atomizing core 140 through the second air outlet 2638, and the second air outlet 2638 is used for allowing the air in the flow guide channel 2636 to flow out of the mounting bracket 260 to enter the atomizing core 140. In this manner, the airflow from the flow guide passage 2636 can enter the atomizing core 140 through the second air outlet 2638, and then the aerosol generated by heating the atomizing core 140 to atomize the aerosol-generating substrate flows into the air outlet passage 212.

In some embodiments, in order to prevent the backflow air from flowing into the core chamber 214 or the electronic control chamber 215 when encountering the condensed condensate, the outer side wall of the middle connecting portion 265 of the mounting bracket 260 is further provided with a liquid storage tank 2656. As a preferred embodiment, two sets of liquid storage tanks 2656 are disposed on an outer side wall of the mounting bracket 260, the two sets of liquid storage tanks 2656 are disposed on two sides of the communicating groove 2654 along the first direction, each set of liquid storage tanks 2656 includes a plurality of liquid storage tanks 2656, all the liquid storage tanks 2656 in the same set are arranged at intervals along the axial direction of the mounting bracket 260, and each liquid storage tank 2656 extends along the circumferential direction of the mounting bracket 260 to form an arc shape. It is to be understood that the number, shape and arrangement position of the reservoirs 2656 are not limited thereto, and may be arranged as needed to meet different requirements.

In some embodiments, as shown in fig. 2, the power module 200 further includes a liquid absorbing member 270, and the liquid absorbing member 270 is inserted into the guiding groove 2632 in the second axial portion 263 and faces the guiding channel 2636 in the axial direction of the mounting bracket 260. In this way, the liquid absorbing member 270 is located between the flow guide passage 2636 and the second air inlet hole 2612, and the condensed water generated by the airflow flowing through the second air inlet hole 2612 and the flow guide passage 2636 can be absorbed by the liquid absorbing member 270, so as to prevent the condensed water from attaching to the electric core 230 or other electric control elements. It is to be understood that the material forming the absorbent member 270 is not limited, and in particular, in one embodiment, the absorbent member 270 is formed of a porous material (e.g., absorbent cotton) having a good absorbent effect.

Referring to fig. 6, in some embodiments, the first axial portion 261 is opened with an activation passage 2614, one end of the activation passage 2614 is communicated with the inner surface of the air inlet 2612, the other end of the activation passage 2614 extends to the electric control chamber 215 for accommodating the microphone 240 along the radial direction of the housing 210, so as to be communicated with the air inlet 2612 and the sensing surface of the microphone 240, and one side surface of the microphone 240 facing away from the activation passage 2614 is communicated with the outside atmosphere. When a user sucks the electronic atomization device 100, airflow is generated in the activation channel 2614 communicated with the air inlet hole 2612 to make the two side surfaces of the microphone 240 form a pressure difference, and the microphone 240 controls the electronic atomization device 100 to open to generate aerosol generating substrate for the user to suck.

It will be appreciated that since the microphone 240 is disposed at the first axial portion 261 of the mounting bracket 260, a side surface of the microphone 240 facing away from the actuation channel 2614 can be better communicated with the outside atmosphere, so that the microphone 240 is more sensitive to actuation.

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

In the research process, the applicant finds that when the sensing surface of the microphone 240 is communicated with the sealed environment formed in the housing 210, because the other surface of the microphone 240 facing away from the sensing surface is communicated with the external atmosphere, a pressure difference is generated between two sides of the microphone 240, which causes the electronic atomization device 100 to start abnormally.

In order to solve the above problem, the air intake hole 2612 of the present application has a sealing surface located downstream of the activation passage 2614, and one end of the first sealing plug 300 inserted in the air intake hole 2612 has a sealing portion 281 which sealingly engages the sealing surface. When the first sealing plug 300 is inserted into the air inlet hole 2612, the first sealing plug 300 is in sealing fit with the sealing surface of the air inlet hole 2612 through the sealing portion 281, the starting channel 2614 is located on one side of the first sealing plug 300 far away from the first air outlet hole 2652, so that the starting channel 2614 is communicated with the outside atmosphere through a gap between the first sealing plug 300 and the air inlet hole 2612, the microphone 240 is located outside the sealed environment formed in the housing 210 and is communicated with the outside atmosphere, and the pressure of the sensing surface of the microphone 240 and the pressure of the other surface opposite to the sensing surface are always kept consistent, so that abnormal starting of the electronic atomization device 100 caused by pressure difference sensed by the microphone 240 due to transportation or external environment change is avoided. Specifically, in one embodiment, the inner surface of the air inlet hole 2612 near one end of the cell chamber 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 forming the sealing surface, so as to be in sealing engagement with the sealing surface of the air inlet hole 2612.

In the electronic atomization device 100, the internal space of the housing 210 is divided into the independently arranged electric core cavity 214 and the at least one electric control cavity 215, and since the airflow channel in the housing 210 is arranged independently of the electric control cavity 215 and avoids most of the area of the electric core cavity 214, the condensate formed in the airflow channel by the backflow airflow does not adhere to the electric control element in the electric control cavity 215, thereby significantly reducing the risk of short circuit. Moreover, after the first sealing plug 300 and the second sealing plug 400 are plugged, the pressures on the two side surfaces of the microphone 240 are always kept consistent, so that the electronic atomization device 100 can be prevented from being abnormally started during transportation or environmental changes.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several implementation modes of the present application, and the description thereof is specific and detailed, but not construed as limiting the scope of the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
