[0035] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 Schematic diagram of the explosion structure of the electronic atomizer 10 in one embodiment of the present application. Figure 2 for Figure 1 A schematic structural diagram of the middle housing 100, Figure 3 for Figure 1 A schematic diagram of the structure of the other side of the middle airway seal 220. The electronic atomizer 10 provided in one embodiment of the present application includes a housing 100 and an atomization module 200, wherein the housing 100 has a conducting tube 110 and a liquid storage tank 120 for storing atomized liquid inside. In a specific setting, the outer wall of the conducting tube 110 and the inner wall of the housing 100 are enclosed to form the liquid storage tank 120, and the conducting tube 110 has an air outlet channel 130 that runs through itself along its own axis. In a specific setting, the housing 100 is preferably made of transparent glass to facilitate observation of the atomized liquid in the liquid storage tank 120.
[0036] The atomization module 200 includes an atomization component 210, an airway seal 220 and a liquid guide 230. The atomization component 210 is connected to the conduction tube 110. The airway seal 220 is arranged between the inner wall of the housing 100 and the atomization component 210. The airway seal 220 has an installation cavity 221 connected to the atomization component 210. The airway seal 220 is also provided with a return air structure 222 and a liquid inlet hole 223 connecting the installation cavity 221 and the liquid storage tank 120. The liquid guide 230 is a porous structure and is arranged in the return air structure 222. The liquid guide 230 is specifically located in the installation cavity 221. When the liquid guide 230 itself absorbs the atomized liquid, the liquid guide 230 covers the return air structure 222. When the atomized liquid absorbed by the liquid guide 230 is atomized, the liquid guide 230 exposes the return air structure 222. In the specific setting, the airway seal 220 is preferably made of silicone.
[0037] It should be noted that, during specific operation, the electronic atomizer 10 is also electrically connected to a power module (not shown). When the electronic atomizer 10 is not started, the atomized liquid in the liquid storage tank 120 enters the mounting cavity 221 of the airway seal 220 from the liquid inlet hole 223, and then flows from the mounting cavity 221 to the liquid guide 230 located in the mounting cavity 221 and the atomization assembly 210 connected to the mounting cavity 221. At this time, the liquid guide 230 soaked with the atomized liquid will cover the air return structure 222, forming a seal for the air return structure 222, and the atomized liquid in the liquid storage tank 120 is not easy to continue to supply liquid, thereby avoiding leakage.
[0038] When the electronic atomizer 10 is started, the atomizer assembly 210 will heat the guide liquid 230 and its own atomized liquid through the installation cavity 221 to generate an aerosol. The aerosol will go out from the air outlet channel 130 for the user to inhale. At this time, the atomized liquid on the guide liquid 230 is heated and volatilized. The porous structure of the guide liquid 230 will not form a seal with the return air structure 222. External air can enter the atomizer assembly 210 through the air outlet channel 130 of the conducting tube 110 or the air inlet hole opened by the power module, and then enter the liquid storage tank 120 after passing through the installation cavity 221, the porous structure of the guide liquid 230 and the return air structure 222, so that the negative pressure in the liquid storage tank 120 is reduced, and the liquid storage tank 120 supplies atomized liquid again.
[0039] The electronic atomizer 10 is provided with a porous structure by setting the liquid guide 230, and the liquid guide 230 absorbs the atomized liquid and covers the return air structure 222, so as to ensure that when the electronic atomizer 10 is not started, the atomized liquid flowing into the liquid guide 230 through the liquid inlet is immersed in the liquid guide 230, so that the liquid guide 230 seals the return air structure 222, and prevents leakage caused by the liquid storage tank 120 continuing to supply liquid; by setting the atomized liquid absorbed by the liquid guide 230 to be exposed to the return air structure 222 when it is atomized Structure 222 ensures that when the electronic atomizer 10 is started, the atomized liquid on the liquid guide 230 is heated and volatilized by the atomizer assembly 210, and the porous structure of the liquid guide 230 will not form a seal with the return air structure 222. External air can reach the return air structure 222 from the conducting tube 120. The return air structure 222 guides the external air into the liquid storage tank 120 to eliminate the negative pressure, so that the liquid storage tank 120 continues to supply liquid to flow into the atomizer assembly 210 to prevent the atomizer assembly 210 from dry burning.
[0040] Combination Figure 4 As shown, Figure 4 for Figure 1A schematic diagram of the structure of the airway seal 220 from another angle. In some embodiments, in order to design the air return structure 222 more conveniently, a preferred embodiment is that the air return structure 222 includes at least one air return channel, the air return channel includes an air return hole 2221 and a first air return groove 2222, the air return hole 2221 penetrates the airway seal 220 to connect the installation cavity 221 with the liquid storage tank 120, the first air return groove 2222 is provided on one side of the airway seal 220 facing the inner wall of the housing 100, one end of the first air return groove 2222 extends to the air return hole 2221, and the other end of the first air return groove 2222 extends to the top of the airway seal 220. In the specific setting, the preferred number of air return channels in the present application is two, and the two air return channels are arranged at intervals on the left and right sides of the liquid inlet 223. It should be noted that the height of the liquid inlet 223 does not exceed the height of the air return channel, so that the atomized liquid in the liquid storage tank 120 flows into the installation cavity 221 from the liquid inlet.
[0041] See again Figure 3 In order for the air return structure 222 to be able to conduct the external air to the liquid storage tank 120 in time, more specifically, the air return structure 222 also includes a second air return groove 2223, which is provided on the inner wall of the mounting cavity 221, and the two ends of the second air return groove 2223 extend to the two air return holes 2221 respectively. In the specific setting, the centers of the two air return holes 2221 are located on the same straight line, and one end of the second air return groove 2223 extends downward from one air return hole 2221, and extends upward to the other air return hole 2221 after bending, so that the second air return groove 2223 is a U-shaped structure with an open upper end. Through the above setting, when the atomized liquid at the bottom of the atomization module 200 is atomized and returned, the external air can be conducted to the liquid storage tank 120 through the second air return groove 2223 in time to reduce the negative pressure of the liquid storage tank 120.
[0042] In order to enable the atomized liquid in the liquid storage tank 120 to flow quickly into the installation cavity 221, in a preferred embodiment, a liquid inlet space 224 is provided on one side of the airway seal 220 facing the inner wall of the housing 100, and a liquid inlet hole 223 is provided in the liquid inlet space 224. In the specific setting, the number of the liquid inlet holes 223 is preferably two, and the two liquid inlet holes 223 are arranged in the liquid inlet space 224 at intervals, and the liquid inlet space 224 and the return air channel are arranged in the airway seal 220 at intervals, and the two return air channels are respectively located on the left and right sides of the liquid inlet space 224, the depth and width of the first return air groove 2222 in the return air channel are smaller than the liquid inlet space 224, and the diameter of the return air hole 2221 is smaller than the liquid inlet space 224.
[0043] More specifically, the diameter of the air return hole 2221 ranges from 0.5mm to 0.6mm, and can be any value between 0.53mm, 0.55mm, 0.58mm, and 0.5mm to 0.6mm. The width of the first air return groove 2222 and the second air return groove 2223 ranges from 0.6mm to 0.7mm, and can be any value between 0.63mm, 0.65mm, 0.68mm, and 0.6mm to 0.7mm.

In the specific setting, the bracket seal 400 is preferably made of silicone. In order to facilitate the flow port 410 to connect the liquid inlet space 224 and the liquid storage tank 120, the flow port 410 runs through the side wall of the bracket seal 400 facing the liquid inlet space 224. To facilitate the communication between the flow port 410 and the air return structure 222 , the flow port 410 extends to the top of the support seal 400 , and a gap exists between the top of the support seal 400 and the top of the first air return groove 2222 .
[0045] It should be noted that when a support seal 400 is sleeved on the outside of the atomizer module 200, in order to facilitate the connection between the conducting tube 110 of the shell 100 and the atomizer assembly 210, a first through hole 420 is opened at the top of the support seal 400. The first through hole 420 is used for the conducting tube 110 to pass through and connect with the atomizer assembly 210.
[0046] See again Figure 1In order to design the atomizer assembly 210 more conveniently, a preferred embodiment is that the atomizer assembly 210 includes a liquid guide bracket 211 and a heating sheet 212.

[0049] Combination Figure 6 As shown, Figure 6It is a structural schematic diagram of the liquid guiding 230 and the heating sheet 212 when they are attached in one embodiment of the present application. In some embodiments, in order to prevent the heating sheet 212 from burning dry and becoming sticky, specifically, the liquid guiding 230 and the heating sheet 212 are attached in an arc shape. In the specific setting, the liquid guiding 230 and the heating sheet 212 can be set as a plate-like structure with an arc as a whole, and the liquid guiding 230 and the heating sheet 212 overlap to achieve an arc-shaped attachment.
