[0028] Example:

[0029] See also Figures 1 to 5The embodiment of the utility model provides an electronic atomization device, which is provided with an atomization airway 211 and a sensing airway 41. The sensing airway 41 includes a first airway 411 and a second airway 413, both of which extend in the radial direction of the electronic atomization device, and a connecting airway 412, whose length extends in the axial direction of the electronic atomization device. The first airway 411 and the second airway 413 are both multi-stage bending airway structures, and in the axial direction of the electronic atomization device, the height of the first airway 411 is higher than the height of the second airway 413. The connecting airway 412 connects the first airway 411 and the second airway 413 respectively, and the end of the second airway 413 away from the connecting airway 412 is connected to the atomization airway 211. The electronic atomization device also includes a microphone assembly 3, which is located at an end of the first airway 411 away from the connecting airway 412, and the microphone assembly 3 is connected to the first airway 411.

[0030] By setting the first air channel 411 and the second air channel 413 to extend in the radial direction of the electronic atomization device, and in the axial direction of the electronic atomization device, the height of the first air channel 411 is higher than the height of the second air channel 413, and the connecting air channel 412 extends in the axial direction of the electronic atomization device, so that the sensing air channel 41 is an air channel that is staggered and connected up and down, and the microphone assembly 3 is located at the end of the first air channel 411 away from the connecting air channel 412. When the leaked atomized liquid and condensate flow into the second air channel 413, the liquid cannot turn from bottom to top and flow into the first air channel 411 at the same time, thereby avoiding the microphone assembly 3 from being immersed in the leaked atomized liquid and condensate, and preventing the microphone assembly 3 from being damaged or short-circuited to cause the risk of the product starting up automatically or catching fire.

[0031] It should be noted that in the event of leakage of atomized liquid during transportation of the electronic atomization device, the design of the induction airway 41 can prevent the microphone assembly 3 from coming into contact with the leaked atomized liquid, thereby reducing the possibility of accidents; moreover, during the use of the electronic atomization device, it can prevent condensation back from affecting the microphone assembly 3, thereby solving the problems of slow response and delay of the microphone assembly 3 during the suction process, and can also avoid the situation of inhaling more air without producing aerosol during suction.

[0032] See also Figure 1 and Figure 2 The electronic atomization device also includes an atomization body 2 and a base assembly 4 arranged at the bottom of the atomization body 2. The atomization airway 211 is arranged on the atomization body 2. The atomization body 2 heats the atomization liquid and generates an aerosol in the atomization airway 211. The first airway 411, the second airway 413, the connecting airway 412 and the microphone assembly 3 are all arranged on the base assembly 4. When inhaling, the gas around the microphone assembly 3 flows through the first airway 411, the connecting airway 412 and the second airway 413 in sequence and is sucked out, thereby forming a pressure difference around the microphone assembly 3, and the microphone assembly 3 is triggered to start the electronic atomization device.

[0033] See also Figure 1 and Figure 2 ( Figure 2 The arrow direction in the figure is the gas flow direction), the base assembly 4 includes a base frame 43, the first air channel 411 is arranged on the side of the base frame 43 close to the atomizing body 2, and the second air channel 413 is arranged on the side of the base frame 43 away from the atomizing body 2, so that the height of the first air channel 411 is higher than the height of the second air channel 413. The base frame 43 is provided with a sensing chamber 434, and the sensing chamber 434 is respectively connected to the microphone assembly 3 and the first air channel 411. When inhaling, the gas flows through the first air channel 411 and puts the sensing chamber 434 in a negative pressure state, so that a pressure difference is generated around the microphone assembly 3, thereby triggering the microphone assembly 3.

[0034] See also Figure 2 , Figure 4 and Figure 5 In some embodiments, the base assembly 4 further includes a first cover plate 44 and a second cover plate 45, the base frame 43 is provided with a first groove 431 and a second groove 432, the two ends of the communicating air passage 412 are respectively connected to the first groove 431 and the second groove 432, the first cover plate 44 covers the first groove 431 to form the first air passage 411, and the second cover plate 45 covers the second groove 432 to form the second air passage 413, thereby achieving the sealing of the sensing air passage 41. It should be understood that since the first groove 431 is a part of the first air passage 411 and the second groove 432 is a part of the second air passage 413, the difficulty of processing and forming the sensing air passage 41 on the base frame 43 can be reduced, and at the same time, it is also conducive to forming a multi-stage bending air passage structure. In other embodiments, holes can be directly dug on the base frame 43 to form the first air passage 411 and the second air passage 413.

[0035] See also Figure 4 and Figure 5 , a plurality of first baffles 46 are arranged in the first groove 431, and the plurality of first baffles 46 are spaced apart along the radial direction of the electronic atomization device to form a multi-stage bending airway structure; a plurality of second baffles 47 are arranged in the second groove 432, and the plurality of second baffles 47 are spaced apart along the radial direction of the electronic atomization device to form a multi-stage bending airway structure, the first baffles 46 can block the atomized liquid or condensed liquid from flowing in the first airway 411, and the second baffles 47 can block the atomized liquid or condensed liquid from flowing in the second airway 413, thereby further preventing the atomized liquid or condensed liquid from flowing to contact with the microphone assembly 3. Moreover, the gas can flow between the gap between the two adjacent first baffles 46 and between the two adjacent second baffles 47, so that the gas can flow in the first airway 411 and the second airway 413, ensuring that the microphone assembly 3 can be triggered normally.

[0036] See also Figure 4 and Figure 5In some embodiments, at least two first baffles 46 are distributed on opposite side walls of the first groove 431, and two adjacent first baffles 46 are staggered, so as to form a multi-stage bending airway structure in the first airway 411; at least two second baffles 47 are distributed on opposite side walls of the second groove 432, and two adjacent second baffles 47 are staggered, so as to form a multi-stage bending airway structure in the second airway 413. In a specific example, four first baffles 46 can be provided, and two are provided on opposite side walls of the first groove 431, so as to form a four-stage bending airway structure; three second baffles 47 can be provided, and one and two are provided on opposite side walls of the second groove 432, so as to form a three-stage bending airway structure.

[0037] According to actual needs, the number of the first baffles 46 in the first groove 431 can also be set to three, five, six, etc., and the number of the second baffles 47 in the second groove 432 can also be set to four, five, six, etc.

[0038] See also Figure 4 and Figure 5 , the length extension direction of the first baffle 46 closest to the microphone assembly 3 is perpendicular to the length extension direction of the first groove 431, which is conducive to blocking the atomized liquid or condensed liquid from flowing to the position where the microphone assembly 3 is located; the length extension direction of the second baffle 47 closest to the atomizing airway 211 is perpendicular to the length extension direction of the second groove 432, which is conducive to blocking the atomized liquid or condensed liquid from flowing into the second airway 413. In a specific example, there are four first baffles 46, the length extension direction of the first baffle 46 closest to the microphone assembly 3 is perpendicular to the length extension direction of the first groove 431, and the remaining first baffles 46 are arranged at an angle; there are three second baffles 47, the length extension direction of the second baffle 47 closest to the atomizing airway 211 is perpendicular to the length extension direction of the second groove 432, and the remaining second baffles 47 are arranged at an angle.

[0039] In some embodiments, the first groove 431 and the second groove 432 may also extend directly in a wave shape, that is, there is no need to set a baffle in the first groove 431 and the second groove 432 .

[0040] See also Figure 1 and Figure 3 The base assembly 4 also includes a circuit board 5, which is located on a side of the base frame 43 away from the atomizing body 2 and is provided with a clearance hole 51. The base frame 43 is provided with a drainage column 433 penetrating the clearance hole 51. The drainage column 433 is provided with a drainage hole, so that the leaked atomized liquid and condensed liquid can flow out through the drainage hole, thereby preventing the atomized liquid and condensed liquid from flowing onto the circuit board 5 and preventing the circuit board 5 from being damaged.

[0041] See also Figure 1 and Figure 3The base assembly 4 further includes a bottom cover 42, which is connected to the atomizing body 2, and the bottom frame 43 is located between the atomizing body 2 and the bottom cover 42, wherein an air inlet cavity communicating with the second air passage 413 and the atomizing air passage 211 is formed between the bottom frame 43 and the atomizing body 2, so that the gas around the microphone assembly 3 can be sucked out and the gas in the air inlet cavity can flow into the atomizing air passage 211. A storage cavity is formed between the bottom cover 42 and the bottom frame 43, and the circuit board 5 is located in the storage cavity. The drain hole communicates with the air inlet cavity and the storage cavity, ensuring that the leaked atomized liquid and condensed liquid can flow into the drain hole and be discharged.

[0042] See also Figure 1 , Figure 2 and Figure 3 The electronic atomization device is also provided with a main air channel 48 penetrating the base frame 43 and the bottom cover 42, one end of the main air channel 48 is connected to the external atmosphere, and the other end is connected to the air inlet cavity. The main air channel 48 includes a first air inlet hole 421 formed on the bottom cover 42, and a second air inlet hole 435 formed on the base frame 43. The first air inlet hole 421 is connected to the external atmosphere and the air inlet cavity, respectively, and the second air inlet hole 435 is connected to the air inlet cavity and the second air channel 413, respectively. When inhaling, the gas enters the air inlet cavity from the first air inlet hole 421, and the gas around the microphone assembly 3 flows into the air inlet cavity through the first air channel 411, the connecting air channel 412 and the second air channel 413. The area around the microphone assembly 3 is in a negative pressure state, thereby generating an air pressure difference. The microphone assembly 3 is triggered, and the atomization body 2 starts heating and atomizing to generate aerosol. At this time, the gas in the air inlet cavity flows into the atomization air channel 211 and carries the aerosol out to be inhaled by the user. In some embodiments, the atomizing body 2 may be provided with dual atomizing cores 21 , each of which is provided with an atomizing airway 211 . The dual atomizing cores 21 may increase the glue output amount and glue output speed.

[0043] See also Figure 1 , Figure 2 and Figure 3 , a first liquid absorbent member 6 is also provided in the air inlet cavity, and / or a second liquid absorbent member 7 is provided in the storage cavity, the second liquid absorbent member 7 is located between the circuit board 5 and the bottom cover 42, and the drainage column 433 is in contact with the second liquid absorbent member 7. Specifically, the atomized liquid and the condensed liquid will flow to the bottom frame 43 and be absorbed and stored by the first liquid absorbent member 6. After the first liquid absorbent member 6 is saturated with storage, the atomized liquid and the condensed liquid leaked from the bottom frame 43 will flow through the drainage hole to be absorbed by the second liquid absorbent member 7, thereby improving the ability of the electronic atomization device to absorb the leaked atomized liquid and the condensed liquid. According to actual needs, both the first liquid absorbent member 6 and the second liquid absorbent member 7 can be oil-absorbing cotton.

[0044] See also Figure 1 , Figure 2 and Figure 3 The electronic atomization device further comprises a housing 1 and a nozzle assembly 8, wherein the base assembly 4 is fixed to the bottom of the housing 1, the atomization body 2 is fixed inside the housing 1, and the nozzle assembly 8 is fixed to the top of the housing 1. The nozzle assembly 8 is provided with a nozzle opening 81, and the diameter of the nozzle opening 81 is larger than the diameter of the first air inlet 421, so that when the main air channel 48 performs the blowing hole test, due to the special shape of the sensing air channel 41, the airflow is insufficient to drive the microphone assembly 3 to start, thereby preventing the bottom of the electronic atomization device from blowing out aerosol.

[0045] See also Figure 1 and Figure 3 In some embodiments, the electronic atomization device also includes an air regulating switch 9 slidably mounted on a side of the bottom cover 42 away from the bottom frame 43, and the sliding track of the air regulating switch 9 at least partially covers the first air inlet hole 421. When the air regulating switch 9 slides to cover part of the first air inlet hole 421, the actual effective aperture of the air intake of the first air inlet hole 421 is reduced, which is beneficial to avoid the airflow driving the microphone assembly 3 to start and prevent the electronic atomization device from self-starting; when inhalation is required, the air regulating switch 9 is slid until the first air inlet hole 421 is fully exposed, so as to maximize the actual effective aperture of the air intake of the first air inlet hole 421, thereby facilitating the airflow driving the microphone assembly 3 to start.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
