An embodiment of the present application provides an aerosol generating device 10 for generating an aerosol, comprising a body 100, an atomizer (not labeled in the figures); the first air passage 210 and the heating element 220 are disposed in the atomizer, the first air passage 210 is used for guiding the aerosol to flow out of the main body 100, the heating element 220 is disposed in the first air passage 210, and at least part of the heating element 220 penetrates through the sidewall of the atomizer. The main body 100 is internally provided with a first receiving chamber (not labeled in the drawing) and a liquid storage member 110, the atomizing member is positioned in the first receiving chamber, the liquid storage member 110 is positioned between an inner wall of the first receiving chamber and the atomizing member, and at least a portion of the liquid storage member 110 is in contact with the heating element 220.

Referring to fig. 2, a limiting plate 120 is disposed inside the main body 100, and the limiting plate 120 encloses and defines a first accommodating cavity, in which the atomizing member is located. The heating element 220 of the present application is disposed in the first air channel 210, and the liquid storage member 110 is disposed in the first accommodating cavity and contacts with the heating element 220, so that the heating element 220 can heat the liquid in the liquid storage member 110, when a user sucks through the first air channel 210, the heating element 220 in the aerosol generating device 10 activates the heating function, so that the liquid to be heated in the liquid storage member 110 is heated to form aerosol, and the aerosol enters the first air channel 210 for the user to suck. It can be understood that the main body 100 of the present application is further provided with a third accommodating cavity (not labeled in the figure), the third accommodating cavity is disposed in parallel with the first accommodating cavity, and the third accommodating cavity is provided with the battery 140, the microphone 150 and the air inlet 130 from top to bottom. The bottom of the first accommodating cavity is provided with a liquid storage piece support piece 160, and the liquid storage piece support piece 160 is used for supporting the liquid storage piece 110 to avoid the liquid storage piece 110 from sliding down.

In summary, the present application can achieve the effects of the aerosol generating device 10 without providing separate accommodating spaces or limiting devices for the heating element 220 and the liquid storage member 110, thereby improving the production efficiency of the aerosol generating device 10 and reducing the production cost. It is understood that the liquid storage member 110 may be an oil absorbing cotton or the like. The heating element 220 may be a heating wire.

Further, referring to fig. 1 to 3, the main body 100 further includes a suction nozzle 170 and a second accommodating chamber 172;

The suction nozzle 170 is provided with an air vent hole 171, and the air vent hole 171 is communicated with the second accommodating cavity 172 and the external environment;

the second receiving chamber 172 communicates with the first receiving chamber.

Because the outflow amount of the gas in the main body 100 is larger than the inflow amount when the user sucks the liquid through the air passage, a negative pressure may be generated in the main body 100 (the first accommodating cavity), and the negative pressure will affect the flow of the heated liquid in the liquid storage member 110, so that the heating element 220 cannot react with the heated liquid in time, and the heating element 220 is damaged by idle burning. The suction nozzle 170 is provided with the ventilation hole 171, and the ventilation hole 171 can enable external air to enter the second accommodating cavity 172 through the ventilation hole 171 and then enter the first accommodating cavity when a user sucks aerosol, so that air pressure balance is realized, the heating element 220 is prevented from being empty, and the service life of the aerosol generating device 10 is prolonged. Meanwhile, since the second accommodating chamber 172 is communicated with the first accommodating chamber, the liquid in the liquid storage member 110 can volatilize and flow out from the ventilation hole 171 when the user sucks the aerosol, so that the user can enjoy the aerosol.

Further, referring to fig. 1 to 3, the ventilation hole 171 is a circular hole, and has a diameter of 0.2mm to 1.5mm. It will be appreciated that the size of the vent 171 will affect the rate of gas exchange within the body 100, and if the vent 171 is less than 0.2mm, the vent 171 will not achieve the desired equilibrium pressure effect due to the low venting efficiency, thereby causing the heating element 220 to burn empty. If the diameter of the ventilation hole 171 is greater than 1.5mm, the ventilation hole 171 may be replaced with the first gas passage 210 to serve as a passage through which gas flows, thereby affecting the ratio of gas flowing through the first gas passage 210 and reducing the content of aerosol finally sucked by the user.

It is understood that the diameter of the ventilation hole 171 may be any one or a range of two of 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, and 1.5 mm.

Further, referring to fig. 1 to 3, the ratio of the diameter of the first air passage 210 to the diameter of the ventilation hole 171 is (1 to 10): 1. the size of the first air passage 210 needs to be greater than or equal to the ventilation holes 171, thereby avoiding the content of aerosol that the user eventually sucks. However, if the ratio of the first air passage 210 to the ventilation hole 171 is too large, the ventilation efficiency of the ventilation hole 171 is too low compared to the air extraction efficiency of the first air passage 210, so that the heating element 220 is damaged due to idle burning. The ratio of the diameter of the first air passage 210 to the diameter of the ventilation hole 171 may be any one or two of 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10.

Further, referring to fig. 1 to 3, the suction nozzle 170 is provided with a second air passage 173, one end of the second air passage 173 is communicated with the first air passage 210, and the other end is communicated with the external environment; the ventilation holes 171 are multiple, and the ventilation holes 171 are uniformly distributed on the inner wall of the second air passage 173 along the circumferential direction of the second air passage 173. Because the ventilation holes 171 are multiple and are arranged along the circumference of the second air passage 173 and uniformly distributed on the inner wall of the second air passage 173, when the air passage air pressure balance is performed, the air pressures of the ventilation holes 171 in the first accommodating cavity and the second accommodating cavity 172 are consistent, so that the air pressure balance on one side of the first accommodating cavity is avoided, and the air pressure imbalance on the other side of the first accommodating cavity causes partial air burning damage of the heating element 220.

Further, referring to fig. 1 to 3, the second air passage 173 includes a connection channel and an opening 174, one end of the opening 174 is communicated with the connection channel, and the opening 174 is gradually enlarged along a direction away from the main body 100, and the connection channel is communicated with the first air passage 210 and the opening 174; wherein the ventilation hole 171 is disposed on the side wall of the opening 174, and the axis of the ventilation hole 171 is parallel to the axis of the first air duct 210.

During use of the ventilation hole 171, the first accommodation chamber and the second accommodation chamber 172 are in a vertical relationship, that is, the gas moves up and down (similar to the flow of the gas in the first gas passage 210) during exchange. In order to enable the gas to directly flow out through the ventilation hole 171 in the up-and-down movement process instead of being converted from up-and-down movement to left-and-right movement and then to flow out through the ventilation hole 171, further improving ventilation efficiency, the embodiment of the present application adopts the arrangement that the ventilation hole 171 is arranged on the side wall of the opening 174, and the axis of the ventilation hole 171 is parallel to the first air channel 210.

Further, referring to fig. 1 to 3, the upper surface of the liquid storage member 110 abuts against the bottom of the second accommodating cavity 172. If a certain gap is formed between the liquid storage member 110 and the second accommodating cavity 172, when the ventilation hole 171 performs the air pressure balancing operation, the path of the external air flowing into the main body 100 or the external air flowing out of the main body 100 is prolonged, so that the ventilation efficiency of the ventilation hole 171 is low, and therefore, the ventilation efficiency of the ventilation hole 171 can be improved, and the empty burning damage of the heating element 220 is avoided. Meanwhile, the liquid storage member 110 is close to the second accommodating cavity 172, so that the user can enjoy the fragrance volatilized by the liquid in the liquid storage member 110.

Further, please refer to fig. 1 to 3. The liquid storage piece 110 is arranged around the outer side wall of the atomization piece and is in interference fit with the first accommodating cavity. When the external air enters the main body 100 through the air inlet 130, condensation may occur due to low air temperature of the external air, and then the liquid formed by condensation is sucked by the user from the air vent 171 and/or the first air passage 210, which affects the user experience. In the prior art, a manner of setting condensed cotton inside the aerosol generating device 10 is generally adopted to prevent condensed liquid from entering the first air channel 210, and the liquid storage member 110 in the present application surrounds the outer side wall of the atomization member and is in interference fit with the first accommodating cavity, so that the liquid storage member 110 can block the flow of the condensed liquid, and no additional devices such as condensed cotton are required, thereby reducing the production cost of the aerosol generating device 10. It is understood that the first accommodating cavity may be larger than the second accommodating cavity 172, so that the liquid storage member 110 can be prevented from sliding to the second accommodating cavity 172 in the first accommodating cavity, and thus the air inlet hole 130 or the liquid leakage can be prevented.

Further, referring to fig. 1 to 3, the aerosol generating device 10 further includes a sealing plug 300 and a sealing patch 400; the bottom surface of the main body 100 is provided with an air inlet hole 130, the shape and the size of the sealing plug 300 are matched with those of the second air passage 173, and at least part of the sealing plug 300 is positioned in the second air passage 173 so as to seal the second air passage 173; the sealing paste 400 is attached to the bottom surface of the main body 100 and seals the air inlet hole 130.

If the liquid storage member 110 is continuously contacted with the external environment through the first air channel 210, the air inlet hole 130 and/or the air vent 171 before the aerosol generating device 10 is not used, the liquid in the liquid storage member 110 may volatilize, thereby affecting the service life of the aerosol generating device 10. The prior art often adopts the structure of a flip cover and the like to seal the air passage and the air inlet hole 130, so that the cost of the aerosol generating device 10 is high.

Further, referring to fig. 2 to 3, the sealing plug 300 is an elastic member and includes an insertion portion, the insertion portion is located in the second air passage 173, a plurality of annular protrusions 310 are disposed on a side wall of the insertion portion, and the annular protrusions 310 are in interference fit with the second air passage 173. Because the sealing plug 300 is an elastic member, and the annular protrusion 310 is disposed on the insertion portion and is in interference fit with the second air passage 173, the tightness of the aerosol generating device 10 can be improved, and a pretightening force can be generated between the annular protrusion 310 and the side wall of the second air passage 173, so that the sealing plug 300 is prevented from slipping.

It is understood that the aerosol generating device 10 includes, but is not limited to, aerosol generating devices, aromatherapy machines, pharmaceutical nebulizers, fire protection spray systems, cleaning devices, irrigation devices, cosmetic devices, laboratory solute extraction devices, and the like.

This application may be embodied in many different forms, but rather, embodiments are provided in order to provide a thorough and complete understanding of the present disclosure.
