[0032] The present application provides an aerosol atomization device 100, as shown in Figure 1 The aerosol generating device 100 can be used for atomization of an aerosol generating substrate to generate an aerosol. The aerosol atomization device 100 includes a liquid reservoir 10 and an atomizer 20. The liquid reservoir 10 is connected to the atomizer 20 after the end cap 2 is removed. The atomizer 20 is used to atomize the liquid from the liquid reservoir 10 to generate an aerosol. The present application provides an embodiment of the liquid reservoir 10, as shown in Figure 2 , Figure 3 , Figure 4 The liquid reservoir 10 includes a housing 1, an end cap 2, and a movable element 3. The end cap 2 is removably connected to the housing 1 to cover the liquid outlet 12. The movable element 3 is disposed inside the end cap 2 and exposes a portion of the operating portion 32 for the user to press. The user must press the operating portion 32 in advance to make the operating portion 32 support the internal structure of the end cap 2 and then take out the end cap 2. In this way, even if a child accidentally touches the end cap 2, it cannot be directly removed, which ensures the safety of children and also ensures the convenience of use for adults.

[0033] Specifically, the shell 1 comprises a liquid storage cavity 11, a liquid outlet 12 and a first locking part 13, and the first locking part 13 is provided with a first clamping jaw 134. The end cover 2 comprises a second locking part 21, and the second locking part 21 comprises two elastic arms 211, which are composed of a first part 2111, an inclined surface 2112 and a second part 2113, and the second part 2113 is provided with a second clamping jaw 212. The movable part 3 is composed of a sealing part 31 and a manipulating part 32. When in use, the user needs to press the manipulating part 32 on the movable part 3 in advance, at this time, the manipulating part 32 will generate a squeezing force on the inclined surface 2112 to spread the second clamping jaw 212 to both sides, so that the second clamping jaw 212 is separated from the first clamping jaw 134. This design uses the cooperation and separation of the clamping jaws to realize the locking and unlocking of the lock, which improves the reliability and safety of the operation.

[0034] The liquid storage device 10 provided by the embodiment can drive the second locking part 21 to move or at least partially deform by pressing the manipulating part 32, so that the first clamping jaw 134 and the second clamping jaw 212 change from the locked state to the unlocked state, and then the end cover 2 can be removed from the shell 1.

[0035] In one embodiment of the application, the aerosol generating substrate comprises at least one liquid of an aerosol forming material, for example, the aerosol forming material comprises glycerol. In some alternative examples, the aerosol generating substrate can comprise tobacco extract, betel extract or other plant extract, can also comprise synthetic alkaloids, and can also comprise pharmaceutical ingredients. For example, the aerosol forming material comprises a combination of nicotine salt, glycerol, propylene glycol and cooling or flavoring agents. It has been found that the aerosol forming material improves the sensory performance of the aerosol generating substrate by helping to transfer compounds, such as flavor compounds, from the aerosol generating material to the consumer.

[0036] In one embodiment of the application, as Figure 3As shown, the end of the liquid reservoir 10 is provided with two liquid outlets 12, i.e. a first liquid outlet 121 and a second liquid outlet 122, which are spaced apart from each other. Specifically, when the user inhales, the aerosol atomization device 100 is in a vertical or inclined state, and the liquid level of the liquid substrate in the liquid storage cavity 11 does not reach the liquid outlet 12. At this time, the wicking element in the atomizer 20 absorbs the liquid substrate from the bottom to the top through the first liquid outlet 121 and the second liquid outlet 122 and provides the heating element for heating and atomization. At the same time, the first liquid outlet 121 and the second liquid outlet 122 are both provided with gaps to allow air to enter the liquid storage cavity 11, so as to maintain the balance between the internal pressure of the liquid storage cavity 11 and the external atmospheric pressure. When the user stops inhaling and places the aerosol atomization device 100 flat, the first liquid outlet 121 and the second liquid outlet 122 maintain a height difference along the thickness direction of the aerosol atomization device 100, and the liquid level of the liquid substrate in the liquid storage cavity 11 will overflow the first liquid outlet 121, so that the liquid substrate flows into the atomizer 20 through the first liquid outlet 121, while the liquid level of the liquid substrate in the liquid storage cavity 11 does not overflow the second liquid outlet 122, and the second liquid outlet 122 still maintains the air inlet function, and air is supplemented to the liquid storage cavity 11 through the second liquid outlet 122, so as to maintain the balance between the internal pressure of the liquid storage cavity 11 and the external atmospheric pressure. This design allows the electronic cigarette to maintain smooth air supply into the liquid storage cavity 11 in different use postures, ensuring stable supply of the liquid substrate and atomization effect.

[0037] In an embodiment of the present application, as shown in Figure 2 、 Figure 3 The liquid reservoir 10 further comprises a sealing member 31 for sealing the liquid outlet 12, which is retained in the end cover 2 and can be removed together with the end cover 2. The sealing member 31 tightly fits on the liquid outlet 12, effectively preventing leakage of the liquid substrate, thereby keeping the liquid inside the liquid reservoir 10 in a closed state.

[0038] In an embodiment of the present application, the sealing member 31 is made of heat-resistant and corrosion-resistant material, which can ensure that the sealing member 31 still maintains its sealing performance in high temperature or chemical environment, thereby reducing the safety risk caused by leakage.

[0039] In an embodiment of the present application, the sealing member 31 is made of flexible material, and the movable member 3 is part of the sealing member 31, so that the sealing member 31 can better adapt to the shape of the liquid outlet 12 and provide a tighter sealing effect. In addition, the movable member 3 as part of the sealing member 31 can simplify the structure and reduce the production cost.

[0040] In another embodiment of the present application, the movable member 3 is made of hard material, and the movable member 3 is connected to the sealing member 31. This design improves the strength and durability of the movable member 3, so that it can withstand greater operating force while maintaining a close connection with the sealing member 31.

[0041] In one embodiment of the present application, the movable member 3 includes a manipulation portion 32 that can be pressed by the user, and at least part of the manipulation portion 32 is exposed outside the end cover 2, so that the user can conveniently operate the movable member 3 to achieve the removal of the end cover 2.

[0042] In one embodiment of the present application, as shown in Figure 2 、 Figure 4 The two elastic arms 211 each include a first portion 2111 connected to the body of the end cover 2 and a second portion 2113 away from the body of the end cover 2, the width between the first portions 2111 of the two elastic arms 211 is consistent with the width of the movable member 3, and the width between the second portions 2113 of the two elastic arms 211 is less than the width of the movable member 3.

[0043] In one embodiment of the present application, the first portion 2111 and the second portion 2113 are connected by a slope 2112. This design utilizes the guiding effect of the slope 2112, so that the manipulation portion 32 can move from the wider first portion 2111 to the narrower second portion 2113, and the second portion 2113 of the elastic arm 211 will be outwardly expanded after being pressed by the manipulation portion 32, so that the first pawl 134 and the second pawl 212 are disengaged from each other.

[0044] In one embodiment of the present application, the movable member 3 is configured to be pressed by the user to generate movement, and the movement direction of the movable member 3 is opposite to the removal direction of the end cover 2. This reverse movement design makes it difficult for children to perform the correct operation sequence when trying to open the liquid reservoir.

[0045] It should be noted that the present application provides a preferred embodiment in the specification and drawings thereof, but is not limited to the embodiments described in the specification, and further, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications shall fall within the scope of the claims appended to the present application.
