The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0037] As Figures 1 to 4 shown, this embodiment provides an electronic atomization device, which can prevent the microphone head controller 21 from starting up automatically.

[0038] The electronic atomization device includes a housing 1, a circuit board 2, a microphone head controller 21, a seal 3 and a first liquid suction member 4. The circuit board 2, the microphone head controller 21, the seal 3 and the first liquid suction member 4 are all arranged in the housing 1. The housing 1 is provided with an air inlet 12 and an air outlet 13. The circuit board 2 has a first mounting surface and a second mounting surface opposite thereto, as well as a through hole 22 and a first sensing channel 23 penetrating through the first mounting surface and the second mounting surface. The through hole 22 and the first sensing channel 23 are arranged at intervals. The through hole 22 is respectively communicated with the air inlet 12 and the air outlet 13 to form an air flow channel, so that external air can enter the housing 1 from the air inlet 12 and flow out of the housing 1 from the air outlet 13 after passing through the air flow channel.

[0039] Wherein, the microphone head controller 21 has a first sensing surface facing the first mounting surface and a second sensing surface opposite to the first sensing surface. The microphone head controller 21 is arranged on the first mounting surface. The first sensing surface is communicated with the first sensing channel 23, and the second sensing surface is communicated with the air flow channel. In the example shown in the figure, the first sensing channel 23 is communicated with the first part of the air flow channel between the through hole 22 and the air inlet 12; in other examples, the first sensing channel 23 can also be communicated with the outside of the electronic atomization device. At the same time, the seal 3 has a receiving cavity 32 and a second sensing channel 34 communicated with the receiving cavity 32. The seal 3 is arranged on the first mounting surface for receiving the microphone head controller 21 in the receiving cavity 32 and making an airtight seal between the first sensing surface and the second sensing surface. The second sensing channel 34 is used for communicating the second sensing surface with the second part of the air flow channel between the through hole 22 and the air outlet 13. The first sensing surface of the microphone head controller 21 is communicated with the first part of the air flow channel through the first sensing channel 23, so that the first sensing surface is communicated with the atmosphere, and the second sensing surface of the microphone head controller 21 is communicated with the second part of the air flow channel through the second sensing channel 34. Thus, when the user sucks through the air outlet 13, a pressure difference can be formed between the first sensing surface and the second sensing surface, so that the microphone head controller 21 can judge whether the user sucks by detecting the pressure difference.

[0040] In this electronic atomization device, the first liquid absorption member 4 is disposed on the second mounting surface and avoids the air passing hole 22 and the first sensing channel 23. At least a part of the first liquid absorption member 4 is disposed between the air passing hole 22 and the first sensing channel 23, and can be used to isolate the air passing hole 22 and the first sensing channel 23, avoiding the situation where after the aerosol passing through the air passing hole 22 generates condensate when contacting the circuit board 2, the condensate flows into the first sensing channel 23. Moreover, the first liquid absorption member 4 can absorb the condensate, avoiding the self-start of the microphone head controller 21 and affecting the user experience. At the same time, the sealing member 3 houses the microphone head controller 21 in the housing cavity 32 and makes the first sensing surface and the second sensing surface hermetically sealed, preventing the condensate from flowing from the first sensing surface into the second sensing surface and causing the self-start of the microphone head controller 21.

[0041] As Figure 3 and Figure 4 shown, the sealing member 3 abuts against the first mounting surface to form a seal, thereby preventing the occurrence of a gap between the sealing member 3 and the first mounting surface, resulting in air leakage and liquid leakage, which affects the normal use of the electronic atomization device. Optionally, the surface of the sealing member 3 facing the first mounting surface has a convex ring 33, and the convex ring 33 abuts against the first mounting surface. By the setting of the convex ring 33, the seal between the sealing member 3 and the first mounting surface can be further strengthened, effectively preventing the generated condensate from flowing and penetrating into the microphone head controller 21 and causing self-start. Optionally, the sealing member 3 is made of silica gel material. Of course, the sealing member 3 can also be made of other materials, and this embodiment does not make specific limitations.

[0042] Furthermore, the sealing member 3 has a communication cavity 31, and the communication cavity 31 is used to communicate the second sensing channel 34 and the second part of the air flow channel. Through the setting of the communication cavity 31, when the user sucks, a negative pressure can be formed on one side of the communication cavity 31, realizing a pressure difference between one side of the first sensing channel 23 and one side of the second sensing channel 34. Optionally, a second liquid absorption member 35 is disposed in the communication cavity 31, and the second liquid absorption member 35 can absorb the condensate in the communication cavity 31 to prevent the self-start of the microphone head controller.

[0043] Furthermore, a battery assembly 5 electrically connected to the circuit board 2 is further disposed in the housing 1. The battery assembly 5 is disposed between the first liquid absorption member 4 and the bottom of the housing 1, so that the battery assembly 5 can store electrical energy and supply power to the circuit board 2 and the microphone head controller 21. Specifically, the first liquid absorption member 4 has an avoidance channel 41, and the avoidance channel 41 is used to communicate the air passing hole 22 and the air inlet 12, and the avoidance channel 41 extends in the direction of the housing 1, thereby preventing the battery assembly 5 from blocking the avoidance channel 41 and further increasing the air flow rate.

[0044] Among them, a charging port 11 is provided at the side end of the outer shell 1, and a charging connector 24 is arranged on the circuit board 2. The charging connector 24 is exposed to the outside through the charging port 11. Thus, the charging connector 24 can be externally connected to a power source through the charging port 11 to charge the battery assembly 5. Optionally, the charging connector 24 is located on the side of the circuit board 2 away from the seal 3, and the inside of the outer shell 1 is sequentially connected to the outside through the charging connector 24 and the charging port 11. Thus, after the aerosol flows from the air vent 22 into the side of the outer shell 1 where the battery assembly 5 is located, it can flow to the outside sequentially through the charging connector 24 and the charging port 11, or the outside air can flow into the outer shell 1 sequentially through the charging port 11 and the charging connector 24.

[0045] As Figure 1 and Figure 2 shown, the electronic atomization device further includes an atomization assembly 6. The atomization assembly 6 is arranged inside the outer shell 1. The atomization assembly 6 is located on one side of the first mounting surface of the circuit board 2. Specifically, the atomization assembly 6 is located on the side of the seal 3 away from the circuit board 2, and the second part of the air flow channel can pass through the atomization assembly 6. The atomization assembly 6 can atomize the liquid matrix into aerosol. At the same time, the electronic atomization device further includes a mouthpiece assembly 7. The mouthpiece assembly 7 is connected to the side of the outer shell 1 that houses the atomization assembly 6. The mouthpiece assembly 7 is connected to the atomization assembly 6 through the air outlet 13. Thus, the user can suck the aerosol atomized by the atomization assembly 6 through the mouthpiece assembly 7.

[0046] Optionally, the atomization assembly 6 is a dual atomization core. The mouthpiece assembly 7 can be connected to one of the dual atomization cores, and the user can rotate and adjust the mouthpiece assembly 2 so that the mouthpiece assembly 7 is connected to the other of the dual atomization cores to improve the user experience. Correspondingly, the outer shell 1 is further provided with a first air outlet corresponding to the first atomization core and a second air outlet corresponding to the second atomization core. The circuit board 2 is further provided with a first air vent corresponding to the first atomization core and a second air vent corresponding to the second atomization core. The first air vent is connected to the first air outlet and the air inlet 12 to form an air flow channel for the first atomization core; the second air vent is connected to the second air outlet and the air inlet 12 to form an air flow channel for the second atomization core. Part of the first liquid absorbent 4 can be arranged between the first air vent and the second air vent to prevent the condensate from blocking the first air vent or the second air vent. It can be understood that each atomization core can be correspondingly provided with a microphone controller 21 and its associated technical features, such as the first sensing channel 23 on the circuit board 2 and the second sensing channel 34 on the seal 3, etc.

[0047] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
