Referring to fig. 1 and 2, an embodiment of the present application provides an atomizing device 100, which includes a housing 10, an atomizing assembly 20, a base assembly 30, a negative pressure actuator 40, and an elastic membrane 50.

The housing 10 may have a cylindrical shape with openings at both ends.

The atomizing assembly 20 is disposed within the housing 10. Specifically, the atomization assembly 20 includes an oil storage bin 21, an atomization core 22, an atomization tube 23, an upper sealing member 24 and a lower sealing member 25, wherein the atomization tube 23 is arranged in the oil storage bin 21 in a penetrating manner, the upper sealing member 24 and the lower sealing member 25 are respectively sealed at two ends of the oil storage bin 21, an oil storage cavity 211 is defined among the oil storage bin 21, the atomization tube 23, the upper sealing member 24 and the lower sealing member 25, and porous members 26 such as oil storage cotton can be further arranged in the oil storage cavity 211. The atomizing pipe 23 is provided with an atomizing channel 231, the atomizing core 22 is arranged in the atomizing channel 231, the atomizing pipe 23 is provided with an oil inlet hole, and the oil inlet hole is communicated with the oil storage cavity 211 and the atomizing core 22. The atomizing core 22 is capable of heating and atomizing the tobacco tar from the reservoir 211, thereby generating aerosol which is discharged from the atomizing channel 231.

Further, the atomizing device 100 further includes a suction nozzle 60, and the suction nozzle 60 is mounted at one end of the housing 10 and is communicated with the atomizing channel 231, and the suction nozzle 60 can be sucked by a user.

The bottom assembly 30 is disposed at one end of the housing 10, i.e., the end remote from the suction nozzle 60, and below the atomizing assembly 20.

The negative pressure actuating member 40, i.e. the microphone actuating member, the negative pressure actuating member 40 can form a negative pressure to the negative pressure actuating member 40 when the user inhales the air through the nozzle to the atomizing channel 231, and the negative pressure can trigger the negative pressure actuating member 40 to actuate, so that the energy storage member 70 provides current to the atomizing assembly 20, wherein the energy storage member 70 may comprise a battery.

The negative pressure actuator 40 is provided on the bottom assembly 30 and has a sensing side 41 and an atmosphere side 42, the atmosphere side 42 being in communication with the outside.

The elastic film 50 is covered on the sensing side 41 and is fixed between the negative pressure actuator 40 and the bottom assembly 30 to form a deformation cavity 51 with the negative pressure actuator 40. Specifically, the elastic film 50 may include a Polyethylene (PE) elastic film, and may also include films of other materials, which is not particularly limited. Wherein, the polyethylene elastic film has corrosion resistance and good mechanical property.

Wherein, the bottom assembly 30 is provided with an air inlet channel 31 communicating the outside with the atomization channel 231, and the outside air can enter the housing 10 through the air inlet channel 31, and further enter the atomization channel 231.

The air inlet channel 31 and the negative pressure actuator 40 are independent from each other, specifically, the air flow entering through the air inlet channel 31 does not contact the negative pressure actuator 40.

The outer side of the elastic membrane 50 is positioned on the air flow path of the air inlet passage 31 toward the atomizing passage 231. I.e. the air pressure on the outside of the elastic membrane 50 is the same as the air pressure of the nebulization channel 231. Specifically, the elastic membrane 50 extends upward, the air flow path of the air inlet passage 31 toward the atomizing passage 231 extends upward, and the outer side of the elastic membrane 50 is located at the side of the air flow path.

In practical application, when a user sucks in the housing 10 through the atomization channel 231, the air pressure outside the elastic film 50 is pumped away to reduce the air pressure to be less than the air pressure to form a negative pressure, and the air pressure inside the deformation cavity 51 is equal to the air pressure because the air side 42 of the negative pressure starting member 40 is communicated with the outside air, so that the elastic film 50 moves in the suction direction to deform, specifically moves in the air flow path direction to deform, so that the volume of the deformation cavity 51 changes, and the difference between the air pressure inside the deformation cavity 51 and the air pressure is caused, thereby triggering the negative pressure starting member 40.

When the user stops sucking, the external atmosphere enters from the air inlet channel 31 to the outside of the elastic film 50, so that the air pressure of the outside of the elastic film 50 is equal to the air pressure, and the deformation can be recovered, so that the air pressure in the deformation cavity 51 is equal to the air pressure, and the negative pressure starting piece 40 cannot be triggered.

Therefore, in the atomization device 100 of the present application, under the condition that the normal triggering of the negative pressure starting member 40 is not affected, the elastic film 50 is covered on the sensing side 41 of the negative pressure starting member 40, so that the negative pressure starting member 40 can be protected, condensate is prevented from flowing to the negative pressure starting member 40, and the negative pressure starting member 40 is ensured to work normally.

As shown in fig. 3 to 5, in the embodiment of the present application, the bottom assembly 30 includes a base 32 and a bottom cover 33, the bottom cover 33 is provided to an end of the case 10, and the base 32 is provided to a side of the bottom cover facing the inside of the case 10.

The bottom cover 33 is provided with a communication channel 331, and the communication channel 331 communicates the atmosphere side 42 with the outside. Specifically, the atmosphere side 42 of the negative pressure actuator 40 is exposed to the side of the base 32 facing the bottom cover 33 to communicate with the communication passage 331.

The bottom cover 33 is further provided with an air inlet part 332 protruding towards the base 32, the air inlet part 332 is provided with an air inlet channel 31, the base 32 is provided with a matching hole 321, and the air inlet part 332 extends into the matching hole 321 to be matched with the matching hole in a sealing way, so that the air inlet channel 31 is communicated with the outer side of the elastic film 50. Specifically, the base 32 is an elastic base 32, so that the air inlet 332 extends into the matching hole 321 to be in sealing fit with the air inlet.

By the way that the base 32 and the bottom cover 33 are fitted, the overall structure can be simplified, and the independent air intake passage 31 and the communication passage 331 can be formed so as to be independent of each other between the air intake passage 31 and the negative pressure actuator 40.

Further, the bottom cover 33 forms a communication chamber 34 between the outside of the air intake portion 332 and the base 32, and the communication chamber 34 communicates the communication passage 331 and the atmosphere side 42. By providing the communication chamber 34, the space in which the atmosphere side 42 of the negative pressure actuator 40 communicates with the outside atmosphere can be enlarged, and it is ensured that the atmosphere side 42 remains in communication with the outside.

In this way, the elastic film 50 is fixed between the negative pressure starting member 40 and the inner wall of the fixing cavity 35 in a simple manner, and the position of the elastic film 50 relative to the negative pressure starting member 40 is stabilized, so that the protection and the working stability of the elastic film 50 to the negative pressure starting member 40 are improved.

In some embodiments, the first portion 52 further includes a second sub-portion 522, the second sub-portion 522 being cylindrical, and one end of the second sub-portion 522 being connected to the lower end of the first sub-portion 521, the other end of the second sub-portion 522 extending downward.
