A first mounting groove 221 is provided on the surface of the connecting plate portion 22 connected to the suction portion 21, and the liquid storage component 3 and the end wall of the shell 1 are clamped on the connecting plate portion 22. Therefore, the reliability of fixing the suction nozzle 2 is enhanced. In one embodiment, the suction nozzle 2 and the shell 1 are an integrally formed structure, so the connection method of the suction nozzle 2 and the shell 1 can be selected according to needs.

[0028] The liquid storage assembly 3 is located in the outer sleeve 11, and includes a liquid storage tube 31, an elastic sealing top cover 32 and an elastic sealing base 33.

The first atomizing chamber 41 is located between the first side of the absorbent fiber member 4 and the second atomizing chamber 42.

[0033] The outer peripheral surface of the liquid-absorbent fiber member 4 is provided with a first exhaust groove 43, the first end of the first exhaust groove 43 is communicated with the air guide groove 331, and the second end of the first exhaust groove 43 is communicated with the exhaust hole 321. Therefore, when in an environment with low external air pressure such as inside an airplane, the air on the bottom and side of the liquid-absorbent fiber member 4 can be released through the suction nozzle 2, thereby avoiding leakage. The liquid-absorbent fiber member 4 is spaced apart from the elastic sealing top cover 31, and a ventilation gap is formed between the liquid-absorbent fiber member 4 and the elastic sealing top cover 31, and the first exhaust groove 43 is communicated with the exhaust hole 321 through the ventilation gap.

[0034] The liquid-absorbent fiber member 4 further includes a second exhaust groove 44 extending in the longitudinal direction of the liquid-absorbent fiber member 4, and the second exhaust groove 44 is located at the second side of the liquid-absorbent fiber member 4. The first end of the second exhaust groove 44 is connected to the air guide groove 331, and the second end of the second exhaust groove 44 is connected to the suction nozzle 2. Therefore, when in an environment with low external air pressure such as inside an airplane, the air at the second side of the liquid-absorbent fiber member 4 can also be released through the suction nozzle 2. It can be understood that the first side of the liquid-absorbent fiber member 4 and the second side of the liquid-absorbent fiber member 4 can be a flat surface, a cambered surface or a curved surface, etc., which is not specifically limited here.

[0035] The heating component 5 includes a fixed sleeve 51, a porous liquid guide tube 52, a heating element 53 and a wire 54. The first end of the fixed sleeve 51 is inserted in the connecting groove 332, and the second end of the fixed sleeve 51 is located in the second accommodating chamber 310. The porous liquid guide tube 52 is inserted in the fixed sleeve 51, and is used to absorb the atomized liquid in the liquid-absorbing fiber member 4. The heating element 53 is located in the porous liquid guide tube 52, and is used to atomize the atomized liquid. The wire 54 is connected to the heating element 53 and passes through the air inlet 334, so that the atomized liquid is better prevented from leaking from the elastic sealing base 33. It can be understood that as long as the heating element 53 can atomize the atomized liquid at the first atomizing chamber 41, the structure of the heating component 5 is not specifically limited here.

[0036] In this embodiment, there are two heating components 5, and the two heating components 5 are arranged at intervals. The fixed sleeve 51 can be a glass fiber tube or a metal tube, etc., the porous liquid guide tube 52 can be a cotton tube or a ceramic tube, etc., the heating element 53 can be a heating wire or a heating net, and the wire 54 can also pass through the bottom wall of the connecting groove 332, etc., which can be selected according to needs and are not specifically limited here. Please refer to Figure 5 and Figure 6 In another embodiment, the heating component 5 further includes a clamping tube 337, which is located between the connecting column 33 and the multi-hole liquid guide tube 52, and the clamping tube 337 and the fixing sleeve 51 are clamped on the wire 54. Therefore, during assembly, it is not easy to pull the heating element 53, thereby avoiding deformation of the heating element 53 and causing the problem of unstable smoke volume.

[0037] The light board 6 is arranged along the lateral extension of the first accommodating cavity 13, and is located on the side of the liquid storage component 3 facing away from the suction nozzle 2. The first surface of the light board 6 and the second surface of the light board 6 are arranged opposite to each other, and the first surface of the light board 6 is in contact with the fixing frame 8. The light board 6 is used to fix the LED lamp beads 7 so that the LED lamp beads 7 are placed at a preset position of the first accommodating cavity 13. Preferably, the light board 6 is placed on the limiting step 121, thereby enhancing the reliability of the fixation and avoiding displacement during vibration. The LED lamp beads 7 are installed on the surface of the light board 6 facing the liquid storage component 3, and are used to emit light to the light-transmitting portion 14. After the light is emitted from the light-transmitting portion 14, it is easier for the user to pay attention to it, which is convenient for the user to use.

[0038] The first end of the fixing frame 8 is connected to the end of the liquid storage assembly 3 facing away from the suction nozzle 2, and the second end of the fixing frame 8 is buckled and connected to the bottom cover 12. The light board 6 is located in the space formed by the bottom cover 12 and the fixing frame 8, so the structure is compact and easy to assemble. Among them, the fixing frame 8 includes a fixing plate portion 811 located outside the liquid storage assembly, and the fixing plate portion 811 is arranged to extend horizontally along the first accommodating cavity 13.

[0039] The fixed plate portion 811 extends in the direction of the liquid storage assembly 3 to form a first clamping wall portion 812 and a second clamping wall portion 813. The first clamping wall portion 812 is inserted into the elastic sealing base 33, and the elastic sealing base 33 is partially located between the first clamping wall portion 812 and the liquid storage tube 31. The second clamping wall portion 813 is sleeved on the outer peripheral surface of the liquid storage tube 31, so the sealing performance is better and the leakage of the atomized liquid is better avoided. The limiting protrusion 122 is in contact with the fixed plate portion 811, so not only is the connection reliable, but also it is easy to assemble, thereby improving production efficiency.

[0040] The fixing plate portion 811 extends toward the direction where the buckle portion 123 is located to form a buckle arm portion 814, which penetrates the lamp board 6 and is buckled and connected to the buckle portion 123. Therefore, the lamp board 6 does not need additional fixing components to be fixed, which is not only reliable but also simplifies the production process.

The positioning protrusion 815 is located on the side of the controller 92 facing the second direction. Therefore, during assembly, only the bottom end of the controller 92 needs to be inserted into the positioning slot 124 to achieve reliable fixation, thereby facilitating assembly and achieving high production efficiency.

[0042] The battery 91 is located on the side of the fixing frame 8 facing away from the liquid storage assembly 3. The airflow sensor 93 is located in the first mounting groove 221 and is connected to the suction part 21 through the second mounting groove 322 and the third mounting groove 323, so that the airflow sensor is closer to the suction nozzle 2, which can improve the sensitivity of suction. The controller 92 is located outside the first accommodating cavity 221 and is electrically connected to the airflow sensor 93 and connected to the wire 54. When the user sucks at the suction nozzle 2, the airflow sensor 93 is triggered and sends a trigger signal to the controller 92. The controller 92 controls the heating element 53 to generate heat according to the trigger signal, thereby atomizing the atomized liquid in the liquid-absorbing fiber element 4.

[0043] In summary, since the surface of the elastic sealing base 33 of the utility model facing the second accommodating chamber 310 is provided with a connecting groove 332 and a connecting column 333, the connecting groove 332 is arranged around the outer peripheral surface of the connecting column 333, and the connecting column 333 is provided with an air inlet 334, and the air inlet 334 penetrates the end surface of the connecting column 333 facing the second accommodating chamber 310 and the surface of the elastic sealing base 33 facing away from the second accommodating chamber 310, the first end of the heating component 5 is detachably inserted into the connecting groove 332, the second end of the heating component 5 is located in the second accommodating chamber 310, the connecting column 333 extends into the heating component 5, the connecting column 333 and the connecting groove 332 clamp the heating component 5 together, and in addition, the connecting column 333 and the elastic sealing base 33 are an integrally formed structure. Therefore, the atomized liquid in the liquid storage component 3 and the heating component 5 is not easy to leak out, avoiding the influence of the atomized liquid on the electronic components, thereby extending the service life.
