Description

Technical Field

[0001] The utility model relates to the field of atomization equipment, in particular to a liquid storage bottle and an electronic atomization device. Background Art

[0002] In the field of electronic atomization equipment, traditional electronic atomization equipment often faces the troubling problem of liquid leakage during the assembly process. This problem is attributed to the structural setting of the liquid storage bottle in the related technology. In the related technology, the liquid storage bottle and the atomization device are separated. When the atomization device is needed, the liquid storage bottle is assembled into the atomization device. During assembly, the user needs to manually pull out the bottle stopper of the liquid storage bottle. Since the user cannot accurately control the pulling force, some liquid may leak when the bottle stopper is pulled out, and this operation increases the complexity of assembly. At the same time, during the assembly process, the liquid storage bottle can only be assembled in an upright state. If the liquid storage bottle is tilted, liquid may flow out. The limitations of the assembly method are too great. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a liquid storage bottle, which can prevent liquid leakage and reduce assembly steps during the assembly of the liquid storage bottle, and the assembly method of the liquid storage bottle is not restricted.

[0004] The utility model also provides an electronic atomization device having the liquid storage bottle.

[0005] According to the first aspect of the present invention, the liquid storage bottle is used to store atomized liquid, and the liquid storage bottle includes:

[0006] A bottle body, comprising a main body and a limiting part, wherein the main body defines a receiving cavity and an opening communicating with the receiving cavity, and the limiting part is located in the receiving cavity and connected to the main body; and

[0008] Wherein, the first sealing member is configured to be able to slide relative to the bottle body toward the interior of the accommodating cavity until it abuts against the limiting portion, so that the atomized liquid can be guided out of the opening.

[0009] The liquid storage bottle according to the embodiment of the utility model has at least the following beneficial effects: during the assembly process, the first sealing member will slide toward the inside of the accommodating cavity until it abuts against the limiting portion to complete the assembly of the liquid storage bottle and the electronic atomization device. Before abutting against the limiting portion, the first sealing member always seals the opening. The user can directly assemble the liquid storage bottle to the electronic atomization device through the opening, and push the first sealing member to slide through the parts of the electronic atomization device. Therefore, during the assembly process, the atomized liquid will not leak from the opening and the assembly steps are reduced. At the same time, even if the liquid storage bottle tilts during the assembly process, the atomized liquid in the bottle cannot flow out because the first sealing member still closes the opening before the opening is connected to the electronic atomization device. When the first sealing member opens the opening, the opening is also interconnected with the electronic atomization device. The atomized liquid is directly introduced into the electronic atomization device after being guided out from the opening and will not leak to the outside, thereby expanding the assembly method of the liquid storage bottle.

[0045] Next, with reference to the accompanying drawings of the specification, the liquid storage bottle 100 of the first aspect embodiment of the present utility model will be described.

[0046] The embodiment of the present utility model provides a liquid storage bottle 100 for storing atomizing liquid. Among them, the electronic atomizing device 200 is powered by a battery to generate heat, so that the liquid inside the device is heated and converted into an atomized form, so that the user inhales the atomized aerosol to achieve the effect of imitating smoking. The liquid storage bottle 100 is a device that provides atomizing liquid for the electronic atomizing device 200.

[0047] Refer to Figure 1 and Figure 2 As shown, the liquid storage bottle 100 includes a bottle body 110 and a first sealing member 130.

[0048] The bottle body 110 includes a main body 111 and a limiting portion 112. The main body 111 is defined by a accommodating chamber 1111 and an opening 1112. The accommodating chamber 1111 is a chamber for storing substances in the main body 111. The atomized liquid is stored in the accommodating chamber 1111. The opening 1112 is connected to the main body 111. The opening 1112 is a hollow cylindrical structure. The opening 1112 and the accommodating chamber 1111 are interconnected, so that the accommodating chamber 1111 can be connected to the outside world. The atomized liquid can be guided out of the accommodating chamber 1111 through the opening 1112 for use by the electronic atomization device 200. The limiting portion 112 is connected to the main body 111 and is located in the accommodating chamber 1111. One end of the limiting portion 112 is connected and fixed to the main body 111, and the other end plays a limiting role, which is used to hinder the movement of the first sealing member 130.

[0049] In some embodiments, the main body 111 includes a bottle body and an upper cover, the upper cover is covered on the bottle body, the accommodating cavity 1111 is a chamber inside the bottle body, the opening 1112 is provided on the upper cover to communicate with the accommodating cavity 1111, the limiting portion 112 is provided above the upper cover and opposite to the opening 1112, when the upper cover and the bottle body are connected, the opening 1112 is communicated with the outside world, and the limiting portion 112 is located in the accommodating cavity 1111.

[0050] The first seal 130 is connected to the opening 1112 of the bottle body 110. The first seal 130 is used to seal the opening 1112. The definition of sealing is that there is no gap between the first seal 130 and the opening 1112, and the atomization liquid cannot be exported to the outside through the opening 1112. The first seal 130 is press-fitted into the opening 1112 so that the accommodation cavity 1111 cannot communicate with the outside, ensuring that the atomization liquid in the accommodation cavity 1111 cannot be exported through the opening 1112. The first seal 130 can be made of materials with toughness and a large friction coefficient, such as rubber, silica gel and other materials. When the liquid storage bottle 100 is not assembled, the first seal 130 seals the opening 1112, and a frictional force is generated between the first seal 130 and the inner wall of the opening 1112. The frictional force is greater than the gravity of the first seal 130. Therefore, the first seal 130 cannot fall off under the action of gravity and separate from the opening 1112. Therefore, when the first seal 130 is subjected to an external force greater than the frictional force, the first seal 130 can slide relative to the bottle body 110 towards the inside of the accommodation cavity 1111. Since the limiting portion 112 is provided below the opening 1112, after the first seal 130 slides out of the opening 1112, the first seal 130 will abut against the limiting portion 112 and come into contact with and generate friction with the inner wall of the limiting portion 112. It should be noted that it is not that the atomization liquid can be exported from the opening 1112 when the first seal 130 contacts the limiting portion 112, but that when the first seal 130 is completely separated from the opening 1112 and a space through which the atomization liquid can flow is generated between the two, the atomization liquid can be exported from the accommodation cavity 1111 through the opening 1112.

[0051] By sliding the first seal 130 in the bottle body 110 to make the atomization liquid conductive, it is no longer necessary to manually remove the bottle stopper during the process of assembling the liquid storage bottle 100 to the electronic atomization device 200. This not only avoids the situation of atomization liquid leakage when removing the bottle stopper, but also simplifies the assembly steps between the liquid storage bottle 100 and the electronic atomization device 200, improving the assembly efficiency of the user. At the same time, the setting of the first seal 130 also expands the connection method between the liquid storage bottle 100 and the electronic atomization device 200. Since the first seal 130 needs to abut against the limiting portion 112 to generate a space through which the atomization liquid can flow between the first seal 130 and the opening 1112 before opening the opening 1112, and when the first seal 130 abuts against the limiting portion 112 and the atomization liquid can start to be exported, the opening 1112 has also been connected to the inside of the electronic atomization device 200. Therefore, it is not necessary to keep the liquid storage bottle 100 in an upright state during the assembly process. Even if the liquid storage bottle 100 has an inclination angle during assembly and the atomization liquid is exported from the opening 1112, the atomization liquid is directly introduced into the electronic atomization device 200 and will not leak to the outside.

[0052] In some embodiments, refer toFigure 2 As shown in Figure 2 , the limiting part 112 includes a guiding part 1121 and an abutting part 1122. The guiding part 1121 extends along a direction parallel to the central axis of the opening 1112, that is, it extends in the vertical direction, and the extending direction is away from the opening 1112 and towards the inside of the accommodating cavity 1111. The abutting part 1122 is connected to one end of the guiding part 1121 away from the opening 1112 and extends towards the central axis direction, that is, it extends horizontally towards the central axis. Among them, the number of the limiting parts 112 is three, and the limiting parts 112 are arranged in a circumferential array around the central axis of the opening 1112. The circumference formed by the limiting parts 112 has the same inner diameter as the opening 1112, so that after the first seal 130 is separated from the opening 1112, it can abut against the limiting part 112 and continue to slide. It should be noted that when the first seal 130 slides to contact the abutting part 1122, the first seal 130 opens the opening 1112, so that the atomizing liquid can be discharged from the opening 1112. In other embodiments (not shown in the figure), the number of the limiting parts 112 can also be one, or two or other numerical features, as long as the limiting part 112 can provide a limiting effect for the first seal 130.

[0053] In some embodiments (not shown in the figure), the guiding part 1121 may not extend along a direction parallel to the central axis of the opening 1112. For example, the guiding part 1121 is still arranged below the opening 1112, but it can be inclined relative to the central axis of the opening 1112, forming an angle with the central axis of the opening 1112. It can also be that one end of the guiding part 1121 is connected to the main body part 111, and the guiding part 1121 extends horizontally in the accommodating cavity 1111, extending in a direction perpendicular to the central axis of the opening 1112. One end of the guiding part 1121 is connected to the main body part 111, and the other end abuts against the first seal 130. In this setting mode, the limiting part 112 does not have the abutting part 1114, and the first seal 130 is abutted by the end of the guiding part 1121 that is not connected to the main body part 111.

[0054] In another embodiment (not shown in the figure), the bottle body 110 may not be provided with the limiting part 112. When the first seal 130 slides under an external force, the first seal 130 can slide to be completely separated from the opening 1112 and then directly fall to the bottom of the bottle. This can also prevent the atomizing liquid from leaking when the bottle plug of the liquid storage bottle 100 is pulled out and simplify the assembly steps.

[0055] In some embodiments, refer to Figure 1 and Figure 2As shown, the liquid storage bottle 100 further includes a cover body 140. The cover body 140 is connected to the main body portion 111 and covers the opening 1112. The cover body 140 has a shape structure adapted to the opening 1112. Among them, the cover body 140 is press-fitted on the opening 1112. In other embodiments (not shown in the figure), the cover body 140 can be covered on the opening 1112 by means of threaded connection or snap connection. The cover body 140 is used to further seal the opening 1112. If the atomization liquid leaks between the first seal 130 and the opening 1112, the cover body 140 can prevent the atomization liquid from further leaking to the outside. Further, a wall hole 141 is formed in the cover body 140. The wall hole 141 is formed by a plurality of thin wall structures 142. Each of the plurality of thin wall structures 142 has a sharp portion, and the sharp portions are arranged at intervals toward the center of the cover body 140. The gaps between the plurality of thin wall structures 142 form the wall hole 141. The plurality of thin wall structures 142 are made of a ductile material, and the plurality of thin wall structures 142 can move relative to the cover body 140, so that the cover body 140 has an open state and a closed state. Specifically, in the normal state, that is, when the liquid storage bottle 100 is not assembled to the electronic atomization device 200, the cover body 140 is in the closed state, and the sharp portions of the thin wall structures 142 naturally gather together to further seal the opening 1112. When the liquid storage bottle 100 needs to be assembled to the electronic atomization device 200, since the first seal 130 needs to slide under the action of an external force, a pushing element is required to contact the first seal 130 to drive the first seal 130 to slide. The pushing element needs to pass through the cover body 140 before entering the opening 1112 to contact the first seal 130. When the pushing element needs to enter the opening 1112, the pushing element will first act on the plurality of thin wall structures 142, apply an external force on the plurality of thin wall structures 142, and the plurality of thin wall structures 142 will bend toward the inside of the opening 1112 after being subjected to the external force, thereby forming a channel through which the pushing element can enter, so that the pushing element can be inserted into the opening 1112 to contact and push the first seal 130. At this time, the cover body 140 is in the open state, and the plurality of thin wall structures 142 will abut against the outer wall of the pushing element. If the pushing element is taken out again, the plurality of thin wall structures 142 will automatically return to their original state, and the cover body 140 will be in the sealed state again.

[0056] The setting of the cover body 140 enables the liquid storage bottle 100 to have the function of preventing the atomization liquid from leaking to the outside, further preventing the atomization liquid from leaking when the liquid storage bottle 100 is not assembled. At the same time, when assembling the liquid storage bottle 100 to the electronic atomization device 200, the user does not need to manually open the cover body 140, which not only provides further leakage prevention guarantee but also simplifies the operation steps, making the whole assembly process smoother and simpler, and improving the user experience.

[0057] In some embodiments, refer toFigure 3 As shown in Figure 3 , the electronic atomization device 200 includes a housing assembly 210, and the housing assembly 210 has a housing 211 and a liquid storage chamber 212. Among them, the liquid storage chamber 212 is connected to the liquid storage bottle 100, and there is a channel for conducting the atomization liquid between the liquid storage chamber 212 and the liquid storage bottle 100. When the atomization liquid in the liquid storage bottle 100 can be exported from the accommodation cavity 1111 to the outside through the opening 1112, the atomization liquid is exported and then enters the liquid storage chamber 212 through the channel to be atomized into aerosol for the user to inhale. The liquid storage chamber 212 and the liquid storage bottle 100 are both arranged inside the housing 211.

[0058] The housing 211 is a protective component sleeved on the liquid storage bottle 100 and the liquid storage chamber 212, which is used to prevent the internal parts of the electronic atomization device 200 from being damaged and causing the device 200 to malfunction. A protrusion 1113 is provided on the outer wall of the main body portion 111. Specifically, the protrusion 1113 is provided below the main body portion 111, and the protrusion 1113 is made of a material with toughness and a high friction coefficient, such as rubber material, silicone material, etc. The liquid storage bottle 100 is snap-connected inside the housing 211 through the protrusion 1113, so that the liquid storage bottle 100 is fixed in the housing 211 to complete the assembly. The protrusion 1113 makes the liquid storage bottle 100 be installed in the housing assembly 210 with an interference fit, which simplifies the assembly method of the electronic atomization device 200 and makes the assembly more convenient and fast.

[0059] Optionally, the installation method of the liquid storage bottle 100 and the housing assembly 210 is not limited to the interference fit using the protrusion 1113. In other embodiments (not shown in the figure), the liquid storage bottle 100 and the housing assembly 210 can also be connected by screw connection, mortise and tenon connection, or other connection methods such as snap connection.

[0060] Further, refer to Figure 3As shown, the electronic atomization device 200 includes a battery 230, which is connected to the housing assembly 210 and is located inside the outer shell 211. The battery 230 is installed on one side of the liquid storage bottle 100 and the liquid storage chamber 212. A concave wall structure is formed on the side of both the liquid storage bottle 100 and the liquid storage chamber 212 facing the battery 230. The shape of the concave wall structure is adapted to that of the battery 230, and a part of the volume of the battery 230 can be accommodated in the concave wall structure, thereby reducing the overall volume of the electronic atomization device 200 and making it more convenient to carry the electronic atomization device 200. Specifically, the contact surface between the battery 230 and the concave wall structure is fixed by spot welding. In other embodiments, the battery 230 can also be fixedly connected to the concave wall structure by means such as snap fixation and adhesive fixation, as long as the battery 230 is connected to the liquid storage bottle 100 and the liquid storage chamber 212 to achieve the purpose of reducing the volume of the electronic atomization device 200. Further, the main body portion 111 further includes an abutting member 1114, which is disposed below the main body portion 111 and extends in the direction of the battery 230. The abutting member 1114 further has a support structure formed by extending. The support structure is made of a material with toughness and can be bent under the action of an external force and will return to its original position after the external force disappears. After the main body portion 111 is connected to the housing assembly 210 through the protrusion 1113, the abutting member 1114 abuts against the bottom of the battery 230, and the support structure is located between the abutting member 1114 and the battery 230. Under the clamping force of the abutting member 1114 and the battery 230, the support structure will bend toward the side away from the battery 230 and has a tendency to reset, thereby providing a supporting force for the bottom of the battery 230, providing support for the battery 230, further fixing the connection between the battery 230 and the housing assembly 210, and preventing the battery 230 from loosening inside the outer shell 211 to affect the normal operation of the electronic atomization device 200.

[0061] Next, with reference to the accompanying drawings of the specification, the electronic atomization device 200 according to the second aspect embodiment of the present invention will be described.

[0062] Refer to Figure 3As shown, an embodiment of the present utility model provides an electronic atomization device 200, which includes a housing assembly 210, the liquid storage bottle 100 of the above-mentioned first aspect embodiment, an atomization assembly 240, a battery 230, and a control element. Among them, the liquid storage bottle 100 and the atomization assembly 240 are both connected to the housing assembly 210, and the atomization assembly 240, the battery 230, and the control element are accommodated inside the housing assembly 210. After the liquid storage bottle 100 is assembled to the housing assembly 210, the liquid storage bottle 100 and the atomization assembly 240 are connected and communicate with each other, and the atomization assembly 240 can obtain the atomization liquid from the liquid storage bottle 100 to make the electronic atomization device 200 work. Specifically, the housing assembly 210 includes a mouthpiece, and the mouthpiece communicates with the atomization assembly 240. When the user makes a suction action, a negative pressure will be generated inside the electronic atomization device 200. At this time, the control element will sense the negative pressure and send a signal to the atomization assembly 240. There is some atomization liquid in the atomization assembly 240. After receiving the signal from the control element, the atomization assembly 240 will atomize the atomization liquid by heating to generate an aerosol, and the aerosol is discharged through the mouthpiece for the user to inhale. Among them, if continuous atomization causes the atomization liquid in the atomization assembly 240 to be exhausted, the atomization assembly 240 can draw the atomization liquid in the accommodation cavity 1111 through the channel with the liquid storage bottle 100, so that the electronic atomization device 200 can continuously work to generate an aerosol.

[0063] In some embodiments, referring to Figures 3 to 7 As shown, the housing assembly 210 includes a housing 211 and a liquid storage chamber 212. The liquid storage chamber 212 is arranged inside the housing 211. There is a liquid storage cavity 2121 in the liquid storage chamber 212, and the atomization assembly 240 is located in the liquid storage cavity 2121. The liquid storage chamber 212 is provided with a liquid inlet channel 2122, and the liquid inlet channel 2122 communicates the liquid storage cavity 2121 and the opening 1112 so that the atomization liquid can be exported from the opening 1112 and enter the liquid storage cavity 2121 through the liquid inlet channel 2122 for the use of the atomization assembly 240. Further, a second seal 220 is also arranged in the liquid inlet channel 2122. When the liquid storage bottle 100 is assembled to the housing assembly 210, the second seal 220 enters the opening 1112 and contacts the first seal 130, and applies an external force to the first seal 130, thereby pushing the first seal 130 against the limiting part 112 to open the opening 1112 so that the atomization liquid can be exported to the liquid storage cavity 2121.

[0064] In some embodiments, referring to Figures 4 to 6As shown, the second seal 220 includes a push rod 222 and a seal plug 223. The push rod 222 is connected to the seal plug 223. The seal plug 223 is located in the liquid inlet channel 2122, while a part of the push rod 222 extends out of the liquid inlet channel 2122, and the part of the push rod 222 extending out of the liquid inlet channel 2122 contacts the first seal 130. When the liquid storage bottle 100 is assembled to the housing assembly 210, since the first seal 130 needs to be driven by an external force to slide in the bottle body 110, the push rod 222 will cause the thin-walled structure 142 on the cover 140 to expand through the wall hole 141 of the cover 140 to form a channel through which the push rod 222 can contact the first seal 130. During assembly, the push rod 222 will abut against the first seal 130 to prevent the first seal 130 from moving and assembling together with the liquid storage bottle 100, so as to realize the sliding of the first seal 130 relative to the bottle body 110 in the opening 1112. When the push rod 222 pushes the first seal 130 to slide and abut against the abutting member 1122 of the limiting portion 112, a space for the atomized liquid to be exported is formed between the first seal 130 and the opening 1112, so that the atomized liquid can be exported through the opening 1112 to the liquid storage cavity 2121. In some embodiments, the cross-sectional shape of the push rod 222 matches the position distribution of the multiple thin-walled structures 142 of the cover 140, which enables the push rod 222 to better apply an external force on the thin-walled structures 142, thus facilitating the push rod 222 to pass through the cover 140 and enter the opening 1112 to push the first seal 130. In other embodiments, the cross-sectional shape of the push rod 222 may not match the position distribution of the multiple thin-walled structures 142 of the cover 140. For example, the cross-sectional shape of the push rod 222 may be circular, triangular or other shape structures, as long as the push rod 222 can pass through the cover 140 and enter the opening 1112 to contact the first seal 130.

[0065] Further, in some embodiments, during the process of assembling the liquid storage bottle 100 to the housing assembly 210, the second seal 220 will also slide in the liquid inlet channel 2122, and the second seal 220 has a first position and a second position. Refer to Figure 4As shown, at this time, the second sealing member 220 is in the first position, and the sealing plug 223 of the first sealing member 130 closes the lower end of the liquid inlet channel 2122, separating the liquid inlet channel 2122 from the accommodating chamber 1111, so that the atomized liquid in the accommodating chamber 1111 cannot be introduced into the liquid storage chamber 2121 through the liquid inlet channel 2122. At the same time, since there will be a small amount of atomized liquid in the liquid storage chamber 2121, before the liquid storage bottle 100 is assembled, the lower part of the shell 211 of the shell assembly 210 is in an open state, so that the sealing plug 223 closes the lower end of the liquid inlet channel 2122, and the atomized liquid in the liquid storage chamber 2121 can be stably stored in the liquid storage chamber 2121, preventing the atomized liquid originally existing in the liquid storage chamber 2121 from leaking from the lower part of the shell 211 to the outside before the liquid storage bottle 100 is connected to the liquid storage chamber 2121. Figure 5 As shown, at this time, the second sealing member 220 is in the second position, and the second sealing member 220 moves upward from the first position to close the upper end of the liquid inlet channel 2122. When the liquid storage tank 212 needs to be replenished with atomized liquid, the electronic atomization device 200 needs to be inverted so that the atomized liquid flows into the liquid storage chamber 2121 under the action of gravity. Figure 4 As shown, a liquid guide port 2421 is provided in the liquid inlet channel 2122. When inverted, the atomized liquid is conducted to the atomizing device through the liquid guide port 2421. Closing the upper end of the liquid inlet channel 2122 can prevent excessive atomized liquid from leaking from the upper part of the liquid inlet channel 2122 when the electronic atomizing device 200 is in operation. Similarly, closing the liquid inlet channel 2122 is defined as: the sealing plug 223 of the second sealing member 220 is located above the liquid guide port 2421, and the portion above the liquid guide port 2421 is closed. There is no gap between the sealing plug 223 and the inner wall of the liquid inlet channel 2122, so that the atomized liquid cannot leak out through the upper end of the liquid inlet channel 2122.

[0066] See also Figure 4 and Figure 5 As shown, when the liquid storage bottle 100 and the housing assembly 210 are assembled, the second sealing member 220 will be in the first position to push the first sealing member 130 to abut the limiting portion 112. When the first sealing member 130 and the abutting member 1122 of the limiting portion 112 abut each other, the atomized liquid can be discharged from the opening 1112 at this time, but because the sealing plug 223 seals the liquid inlet channel 2122, the atomized liquid cannot enter the liquid storage chamber 2121. At this time, the abutting member 1122 will prevent the first sealing member 130 from continuing to slide toward the inside of the accommodating chamber 1111. The abutting member 1122 and the first sealing member 130 cooperate with each other to provide external force to the second sealing member 220 in the opposite direction so that the second sealing member 220 starts to slide. The second sealing member 220 slides from the first position to the second position under the push of the external force, thereby making the liquid inlet channel 2122 and the accommodating chamber 1111 communicate with each other, so that the atomized liquid can enter the liquid storage chamber 2121.

[0067] Further, in some embodiments, refer to Figure 2 , Figure 4 and Figure 5 As shown, a first friction ring 131 is provided around the outer surface of the first seal 130. The first friction ring 131 is made of a ductile material, so that the first seal 130 is press-fitted into the bottle body 110. When the first seal 130 is located in the bottle body 110, the first friction ring 131 contacts the inner wall of the bottle body 110. Specifically, when the first seal 130 is located at the opening 1112, the first friction ring 131 contacts the inner wall of the opening 1112 to generate friction. When the first seal 130 slides from the opening 1112 to the limiting part 112, the first friction ring 131 contacts the inner wall of the limiting part 112 to generate friction. Therefore, when the first seal 130 slides relative to the bottle body 110, there is always a friction coefficient between the first seal 130 and the inner wall of the bottle body 110. Similarly, refer to Figure 4 and Figure 5 As shown, a second friction ring 221 is provided on the second seal 220. The second friction ring 221 is made of a ductile material, so that the second seal 220 is press-fitted into the liquid inlet channel 2122. When the second seal 220 slides from the first position to the second position, the second friction ring 221 will generate friction with the liquid inlet channel 2122. However, since the friction coefficient between the second friction ring 221 and the liquid inlet channel 2122 is always greater than the friction coefficient between the first seal 130 and the inner wall of the bottle body 110, during the assembly of the liquid storage bottle 100, the first seal 130 will first slide towards the inside of the accommodating cavity 1111 under the drive of the push rod 222 until it abuts against the limiting part 112. When the first seal 130 abuts against the limiting part 112, the limiting part 112 will generate a resistance on the first seal 130, and the resultant force of the friction force and the resistance between the first seal 130 and the inner wall of the bottle body 110 is greater than the friction force between the second friction ring 221 and the liquid inlet channel 2122, thereby reversely driving the second seal 220 to move, so that the second seal 220 moves from the first position to the second position to complete the assembly of the electronic atomization device 200.

[0068] In some embodiments, refer to Figure 7 and Figure 8As shown, the atomization component 240 includes a liquid storage 241, a liquid guiding tube 242, and an atomization core 243. The liquid storage 241 is located in the liquid storage cavity 2121 and has a shape structure adapted to the liquid storage cavity 2121. Among them, the liquid storage 241 is made of cotton material. In other embodiments, the liquid storage 241 can also be made of other materials such as liquid guiding ceramics. Further, the liquid storage 241 includes a first through hole 2411 and a second through hole 2412. The first through hole 2411 and the second through hole 2412 define a chamber. The chambers defined by the two through holes are spaced apart. Among them, the liquid guiding tube 242 is inserted into the first through hole 2411 and is located in the liquid inlet channel 2122. The liquid guiding tube 242 is communicated with the liquid storage bottle 100. At least a part of the liquid guiding tube 242 extends out of the liquid inlet channel 2122 and is connected to the opening 1112, so that after the atomized liquid is exported from the opening 1112, it can flow through the liquid guiding tube 242 into the liquid storage cavity 2121. A liquid guiding port 2421 is provided on the liquid guiding tube 242. The second seal 220 seals the lower end of the liquid guiding tube 242 at the first position and seals the upper end of the liquid guiding tube 242 at the second position. The atomization core 243 is inserted into the second through hole 2412, and the liquid guiding tube 242 is communicated with the atomization core 243 through the liquid guiding port 2421.

[0069] Specifically, referring to Figures 1 to 8 As shown, when the user makes a suction action, a negative pressure will be generated inside the electronic atomization device 200. The control element will sense the negative pressure and thus control the atomization core 243 to start working. The atomization core 243 heats the liquid storage 241 in the atomization core 243 through a heating element to generate aerosol, and the aerosol is discharged to the outside through the mouthpiece for the user to inhale. When the atomized liquid in the atomization core 243 is exhausted, the user needs to invert the electronic atomization device 200 to supplement the atomized liquid. When inverted, the atomized liquid enters the liquid inlet channel 2122 through the opening 1112, and the atomized liquid flows on the liquid guiding tube 242. When the atomized liquid flows to the liquid guiding port 2421, the atomized liquid will be exported from the liquid guiding port 2421 and seep into the liquid storage 241. The liquid storage 241 conducts the atomized liquid to the atomization core 243 so that the atomized liquid is received in the atomization core 243. When the user makes a suction action again, the heating element in the atomization core 243 will heat to atomize the new atomized liquid, so that the electronic atomization device 200 can work continuously.

[0070] In some embodiments, a liquid absorbing member is provided between the atomization core 243 and the mouthpiece. When the atomized liquid is atomized and discharged as aerosol, some aerosol may condense to form condensate and flow back. Setting the liquid absorbing member can prevent the atomized liquid flowing back from re-entering the atomization core 243 to affect the taste of the subsequent atomized aerosol. At the same time, the liquid absorbing member can also adsorb the atomized liquid leaking from the upper end of the liquid inlet opening 1112 when the electronic atomization device 200 is inverted to supplement the atomized liquid, preventing the atomized liquid from flowing out to the outer wall of the housing 211.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the relevant technical field, various changes can be made without departing from the gist of the present utility model. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
