[0009] Furthermore, the partition wall also includes a main body connected to the first isolation section, and the second sub-channel and the transition channel are both formed between the main body and the second liquid storage component.

[0010] Furthermore, the main body includes a second isolation section and a connecting section connecting the first isolation section and the second isolation section.

[0025] Example:

[0026] like Figure 1-4As shown, in this embodiment, the electronic atomizer includes: an oil cup 1 and a bracket 2 installed inside the oil cup 1, as well as a first liquid reservoir 4, a second liquid reservoir 5, and a heating element 3 fixed to the bracket 2; the bracket 2 has a partition wall 21 that longitudinally divides the interior of the oil cup 1 into a liquid reservoir 24 and an atomization chamber 23, that is, an atomization chamber 23 and a liquid reservoir 24 are formed between the oil cup 1 and the bracket 2, and the atomization chamber 23 and the liquid reservoir 24 are separated by the partition wall 21 of the bracket 2; the bracket 2 is also provided with a side of the partition wall 21 facing the atomization chamber 23 and connected to... The mounting groove 25 of the atomizing chamber 23 has a ventilation hole 2112 and a liquid inlet hole 2111 that connect the liquid storage chamber 24 to the mounting groove 25. The first liquid storage component 4 is placed in the mounting groove 25 and covers the ventilation hole 2112 and the liquid inlet hole 2111. The second liquid storage component 5 covers the opening of the mounting groove 25. The heating element 3 is located on the side of the second liquid storage component 5 away from the first liquid storage component 4. A ventilation channel a is formed between the top of the first liquid storage component 4, the top of the second liquid storage component 5, and the bottom of the partition wall 21, connecting the ventilation hole 2112 and the outside.

[0027] Specifically, when the electronic atomizer is working, the ventilation channel a connects the ventilation port 2112 to the outside, creating a pressure difference between the ventilation port 2112 and the liquid inlet port 2111. This allows the atomized liquid stored in the liquid storage chamber 24 to enter the first liquid storage component 4 and the second liquid storage component 5 through the liquid inlet port 2111. The liquid then reaches the heating element 3, where it is heated and atomized to form an aerosol. The generated aerosol travels along the atomization chamber 23 to the outlet channel of the oil cup and is then discharged outside the electronic atomizer for the user to inhale. In this embodiment, the first liquid storage component 4 is located on one side of the ventilation port 2112, forming a first leak-proof barrier that absorbs the atomized liquid flowing out of the ventilation port 2112. The second liquid storage component 5 covers the opening of the mounting groove 25, meaning it is located on one side of the first liquid storage component 4, forming a second leak-proof barrier. Even if leakage occurs and passes through the first liquid storage component 4, it will be absorbed by the second liquid storage component 5, greatly improving the leak-proof performance of the electronic atomizer.

[0028] In some specific examples, the first liquid storage component 4 can be an integral cotton, and the second liquid storage component 5 can be a liquid-conducting cotton, porous ceramic, or porous glass.

[0029] like Figure 2As shown, in this embodiment, the ventilation channel a includes a first sub-channel a1 near the ventilation hole 2112, a second sub-channel a2 away from the ventilation hole 2112, and a transition channel a3 connecting the first sub-channel a1 and the second sub-channel a2; the second sub-channel a2 is higher than the first sub-channel a2 in the longitudinal direction. This height difference design increases the difficulty of leakage flowing out along the ventilation channel a; in addition, since the ventilation hole 2112 is arranged longitudinally, and the first liquid storage component 4 and the second liquid storage component 5 are located below the partition wall 21, the leakage is more easily absorbed by the liquid storage component under the action of gravity, further improving the leak-proof performance of the electronic atomizer. Furthermore, in this embodiment, the cross-sectional area of ​​the first sub-channel a1 is larger than that of the second sub-channel a2, which facilitates air return and helps improve the smoothness of air return in the electronic atomizer. In a specific embodiment, the cross-sectional areas of the first sub-channel a1, the transition channel a3, and the second sub-channel a2 gradually decrease along the direction of the ventilation hole 2112, which can further optimize the air return effect of the electronic atomizer.

[0030] In this embodiment, the partition wall 21 includes a first isolation section 211, a mounting groove 25 disposed on the side of the isolation section opposite to the liquid storage chamber 24, a vent 2112 and a liquid inlet 2111 both disposed in the first isolation section 211, and a first clearance groove 2113 formed by the first clearance groove 2113 and the first liquid storage component 4. Specifically, external gas can enter the vent 2112 through the first clearance groove 2113; the first clearance groove 2113 is located on the bottom side of the first isolation section 211, and the first liquid storage component 4 is located below the first isolation section 211 and forms the first sub-channel a1 with the first clearance groove 2113. Thus, even if leakage occurs, the leakage can be quickly absorbed by the first liquid storage component 4 below as it flows through the first sub-channel a1, reducing the risk of further leakage.

[0031] In this embodiment, the partition wall 21 also includes a main body connected to the first isolation portion 211, and the second sub-channel a2 and the transition channel a3 are both formed between the main body and the second liquid storage component 5. Specifically, the wall structure of part of the ventilation channel a can be constructed on the main body by means of slotting or a combination of slotting and opening, and then the second liquid storage component 5 is fitted with the main body to form the required second sub-channel a2 and transition channel a3. It is understood that in some specific embodiments, the main body may not have slots, and a certain amount of clearance space may be reserved to allow the first sub-channel a1 to communicate with the outside gas, which is not limited here.

[0032] Furthermore, such as Figure 3 and 4As shown, in this embodiment, the main body includes a second isolation portion 212 and a connecting portion 213 connecting the first isolation portion 211 and the second isolation portion 212. The second isolation portion 212 has a second clearance groove 2121, and the connecting portion 213 has a third clearance groove 2131. A second sub-channel a2 is formed between the top of the second liquid storage component 5 and the second clearance groove 2121, and a transition channel a3 is formed between the side of the second liquid storage component 5 away from the atomizing chamber 23 and the third clearance groove 2131.

[0033] Specifically, the bottom side of the partition wall 21 is set as a stepped structure, that is, the bottom height of the second isolation part 212 is higher than the bottom height of the first isolation part 211. The bottom side of the first isolation part 211 is provided with a first clearance groove 2113, and the bottom side of the second isolation part 212 is provided with a second clearance groove 2121. The first isolation part 211 and the second isolation part 212 are connected by a connecting part 213, and a third clearance groove 2131 is provided on the connecting part 213 to connect the first clearance groove 2113 and the second clearance groove 2121. The upper part of the second liquid storage component 5 is surrounded by the third clearance groove 2131 on one side of the connecting part 213 to form a transition channel a3, which greatly increases the difficulty of leakage flowing up along the transition channel a3 and flowing out along the second sub-channel a2, and achieves a good leak-proof effect.

[0034] In this embodiment, the third clearance groove 2131 extends in the longitudinal direction, and the first clearance groove 2113 and the second clearance groove 2121 extend in the transverse direction perpendicular to the longitudinal direction; this makes it easier to block and absorb leakage in a part of the ventilation channel a, while the other part extends in the transverse direction.

[0035] like Figure 1 , 3 As shown in Figures 4 and 5, in this embodiment, the bracket 2 further includes a side wall 22 connected to the first isolation portion 211, and the side wall 22 and the first isolation portion 211 enclose each other to form an installation groove 25. The side wall 22 and the partition wall 21 can be integrally formed. The outer periphery of the partition wall 21 and the outer side of the side wall 22 respectively cooperate with the inner wall of the oil cup 1 and are sealed together. A groove is provided on the inner side of the side wall 22, and the groove and the bottom side of the first isolation portion 211 enclose each other to form an installation groove 25 that is adapted to the shape of the first liquid storage component 4, so that the first liquid storage component 4 can be stably installed in the installation groove 25.

[0036] In some specific embodiments, the side wall 22 includes a main wall 221 and an extension wall 222. The main wall 221 is connected to the edge of the first isolation part 211 away from the connecting part 213. The extension wall 222 is connected between the first isolation part 211 and the main wall 221. The bottom of the mounting groove 25 is formed on the inner side of the main wall 221. That is, part or all of the inner side of the main wall 221 is used to form the bottom of the mounting groove 25. The upper wall surface of the mounting groove 25 is formed on the side of the first isolation part 211 away from the liquid storage chamber 24. The lower wall surface and the side wall surface of the mounting groove 25 are both formed on the inner side of the extension wall 222. That is, part of the inner side of the extension wall 222 is used to form the two side wall surfaces of the mounting groove 25, and another part of the extension wall 222 is used to form the lower wall surface of the mounting groove 25, thereby forming a semi-enclosed mounting groove 25 with an opening facing the atomizing chamber 23.

[0037] like Figure 4 As shown, in this embodiment, there are two vents 2112, which are distributed on opposite sides of the liquid inlet 2111. Correspondingly, there are also two venting channels a, which better stabilize the gas pressure within the liquid storage chamber 24. In this embodiment, multiple liquid inlets 2111 are spaced apart; preferably, three are provided to ensure stable and sufficient liquid intake. Of course, in other embodiments, only one liquid inlet 2111 may be provided, and this is not a limitation.

[0038] like Figure 1-4 As shown, in this embodiment, the electronic atomizer also includes a housing 6, a power supply component 7, etc. The oil cup 1, the bracket 2, the heating element 3, the power supply component 7, etc. can be installed inside the housing 6. The power supply component 7 can be electrically connected to the heating element 3 to supply power to the heating element 3.
