According to the portable electronic cigarette, the liquid injection plug cover and the cross-shaped plug cover block the first opening and the second opening of the liquid injection channel respectively, so that a double-sealing effect is formed on the liquid injection channel, cigarette oil can be prevented from leaking out of the liquid injection channel accidentally, and the use experience of the portable electronic cigarette is effectively improved.

Description

Technical Field

[0001] This application belongs to the field of electronic cigarette technology, and more specifically, relates to a closed structure for an oil storage tank. Background Technology

[0002] Many e-cigarette products on the market currently use a pre-sealed e-liquid tank, which means that a portion of basic e-liquid is pre-filled in the tank. Users can then add e-liquid or flavorings as needed during subsequent use to achieve a mixed flavor experience.

[0003] However, current e-cigarette e-liquid compartments typically use a pluggable cap structure, where the cap is attached to the filling opening via a plug-in connection for easy opening during filling. This pluggable cap structure has shortcomings in terms of sealing, easily causing e-liquid to leak along the pluggable gap during actual use, thus spreading to the product casing and affecting the user experience. Utility Model Content

[0004] The purpose of this application is to provide a sealed structure for the oil storage tank, aiming to solve the problem that current e-cigarette oil storage tanks typically use a pluggable cap structure, where the cap is attached to the liquid filling opening via a plug-in method for convenient opening during liquid filling. However, the pluggable cap structure has insufficient sealing performance, which can easily cause oil to overflow along the pluggable gap during actual use, thus spreading to the product casing and affecting the user experience.

[0005] To achieve the above objectives, the technical solution adopted in this application is to provide a closed structure for an oil storage tank, including an oil storage tank, an injection plug, and a cross plug. The oil storage tank is provided with an oil storage chamber and an injection channel. The injection channel has a first opening communicating with the outside and a second opening communicating with the oil storage chamber. The injection plug is inserted into the first opening to seal the first opening, and the cross plug is embedded in the second opening to seal the second opening. The cross plug is an elastic plug and has a cross-shaped indentation for forming a cross-shaped slit after puncture.

[0006] In one embodiment, the aforementioned oil storage tank enclosure structure further includes a limiting ring tube. The injection channel is provided with a limiting ring platform surrounding the second opening. The cross plug and the limiting ring tube are both located inside the injection channel, and the limiting ring tube abuts against and fixes the cross plug on the limiting ring platform.

[0007] In one embodiment, the aforementioned cross plug cap includes a cross plug body with a cross-shaped indentation and a first convex ring surrounding the outside of the cross plug body. A first concave ring is formed between the cross plug body and the first convex ring. A second convex ring is provided at one end of the limiting ring tube, and a second concave ring is surrounding the outside of the second convex ring. The first convex ring is inserted into the second concave ring on the side facing the second concave ring, and the second convex ring is inserted into the first concave ring on the side facing the first concave ring.

[0008] In one embodiment, the aforementioned limiting ring platform is provided with a limiting ring groove surrounding the second opening, and the first convex ring is inserted into the limiting ring groove on the side facing the limiting ring platform.

[0009] In one embodiment, the outer wall of the oil storage tank is provided with a positioning countersunk hole, and the liquid injection plug includes a cover, a sealing plug and a positioning bolt. The sealing plug and the positioning bolt are both disposed on the cover. The sealing plug is inserted into the first opening, and the positioning bolt is inserted into the positioning countersunk hole. The corresponding cover is tightly attached to the outer wall of the oil storage tank.

[0010] In one embodiment, the outer wall of the oil storage tank is provided with a cover groove, and the first opening and the positioning countersunk hole are both provided on the cover groove, and the cover is adapted to fit into the cover groove.

[0011] In one embodiment, the aforementioned cover includes an adjacent movable cover area and a fixed cover area, a sealing plug is disposed on the movable cover area, a positioning plug is disposed on the fixed cover area, and the oil storage tank enclosure structure also includes a mouthpiece assembly, which is disposed on the oil storage tank and communicates with the oil storage chamber. The mouthpiece assembly abuts against the side of the fixed cover area facing away from the cover groove and avoids the side of the movable cover area facing away from the cover groove.

[0012] In one embodiment, the above-mentioned mouthpiece assembly includes a housing portion and a tube portion passing through the housing portion. The oil storage tank is also provided with an atomizing channel. The atomizing channel has a third opening communicating with the outside and a fourth opening communicating with the oil storage chamber. The housing portion is disposed on the outer wall of the oil storage tank and abuts against the fixed covering area on the side opposite to the cover groove, and avoids the movable covering area on the side opposite to the cover groove. The tube portion passes through the atomizing channel through the third opening and communicates with the oil storage chamber through the fourth opening.

[0013] The beneficial effect of the oil storage tank sealing structure provided in this application is that, compared with the prior art, the oil storage tank sealing structure includes an oil storage tank, an injection plug, and a cross plug. The injection channel has a first opening communicating with the outside and a second opening communicating with the oil storage chamber. The corresponding injection plug is used to seal the first opening of the injection channel, and the corresponding cross plug is used to seal the second opening of the injection channel. The cross plug is an elastic plug structure and has a cross-shaped indentation for forming a cross-shaped slit after puncture. Thus, the cross plug is completely sealed before the initial oil injection operation, only when... The user opens the liquid filling plug and inserts the liquid filling device into the liquid filling channel through the first opening, piercing the cross-shaped indentation. The cross-shaped indentation then forms a cross-shaped slit, allowing the liquid filling device to communicate with the oil storage chamber through the second opening. When the liquid filling device is removed, the cross-shaped slit can quickly spring back and seal the second opening due to its own elasticity. Thus, in this application, the liquid filling plug and the cross-shaped plug respectively seal the first and second openings of the liquid filling channel, thereby forming a double sealing effect on the liquid filling channel. This can prevent e-liquid from accidentally leaking out of the liquid filling channel and effectively improve the user experience of portable electronic cigarettes. Attached Figure Description

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0027] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] Please refer to the following: Figure 1 , Figure 3 , Figure 5 and Figure 6 The present application will now describe an embodiment of a portable electronic cigarette 10. The portable electronic cigarette 10 includes an oil storage chamber enclosure structure 20 and a battery compartment 30. The oil storage chamber enclosure structure 20 includes an oil storage chamber 100, an injection plug 200, and a cross plug 300. The oil storage chamber 100 has an oil storage chamber 101 and an injection channel 102 inside. The injection channel 102 extends linearly. One end of the injection channel 102 has a first opening 103 communicating with the outside, and the other end has a second opening 104 communicating with the oil storage chamber 101. The injection plug 200 is inserted into the first opening 103 to seal the first opening 103. The cross plug 300 is embedded in the second opening 104 to seal the second opening 104. The cross plug 300 is an elastic plug and has a cross-shaped indentation 301 for forming a cross-shaped slit after puncture.

[0030] It should be noted that the aforementioned cross-shaped indentation 301 is a pre-set thin-layer area for forming a cross-shaped slit when the external injection device is punctured. Before the user injects the liquid for the first time, the cross-shaped plug cap 300 is in a completely closed state. Only when the user opens the injection plug cap 200 and inserts the injection device into the injection channel 102 through the first opening 103 and punctures the cross-shaped indentation 301, the cross-shaped indentation 301 immediately forms a cross-shaped slit so that the injection device can communicate with the oil storage chamber 101 through the second opening 104. After the injection device is removed, the cross-shaped slit can quickly rebound and reset under its own elasticity to seal the second opening 104.

[0031] The beneficial effect of the oil storage tank sealing structure 20 provided in this application is that, compared with the prior art, the oil storage tank sealing structure 20 includes an oil storage tank 100, an injection plug 200, and a cross plug 300. The injection channel 102 is provided with a first opening 103 communicating with the outside and a second opening 104 communicating with the oil storage chamber 101. The corresponding injection plug 200 is used to block the first opening 103 of the injection channel 102, and the corresponding cross plug 300 is used to block the second opening 104 of the injection channel 102. The cross plug 300 is an elastic plug structure and has a cross-shaped indentation 301 for forming a cross-shaped slit after puncture. Thus, before the initial oil filling operation, the cross plug 300 completely seals the oil storage tank sealing structure 10. When the user opens the liquid filling plug 200 and inserts the liquid filling device into the liquid filling channel 102 through the first opening 103 and pierces the cross-shaped notch 301, the cross-shaped notch 301 immediately forms a cross-shaped gap so that the liquid filling device can communicate with the oil storage chamber 101 through the second opening 104. When the liquid filling device is removed, the cross-shaped gap can quickly rebound and reset under its own elasticity to block the second opening 104. Thus, in this application, the liquid filling plug 200 and the cross-shaped plug 300 respectively block the first opening 103 and the second opening 104 of the liquid filling channel 102, thereby forming a double sealing effect on the liquid filling channel 102, which can prevent e-liquid from accidentally leaking out of the liquid filling channel 102 and effectively improve the user experience of portable electronic cigarettes.

[0032] In this embodiment, the above-mentioned oil storage tank sealing structure 20 also includes a limiting ring tube 400. A limiting ring platform 105 is coaxially provided at one end of the injection channel 102 with a second opening. The limiting ring platform 105 is arranged around the outside of the second opening 104. The cross plug 300 and the limiting ring tube 400 are both located inside the injection channel 102, and the limiting ring tube 400 abuts against and fixes the cross plug 300 on the limiting ring platform 105, thereby providing a fastening effect on the cross plug 300 and preventing the cross plug 300 from accidentally moving inside the injection channel 102 when subjected to external force or air pressure changes, effectively ensuring the sealing effect of the second opening 104.

[0033] Please refer to the following: Figure 3 , Figure 8 and Figure 9In this embodiment, the cross-shaped plug cap 300 includes a cross-shaped plug body 302 and a first convex ring 303. A cross-shaped recess 301 is located on the cross-shaped plug body 302. The first convex ring 303 is circumferentially connected to the outside of the cross-shaped plug body 302, and a first concave ring 304 is formed between the cross-shaped plug body 302 and the first convex ring 303. The limiting ring tube 400 has a second convex ring 401 at one end facing the second opening 104, and a second concave ring 402 circumferentially disposed outside the second convex ring 401. The first convex ring 303 faces the second concave ring. One side of the 402 is inserted into the second concave ring 402, and the second convex ring 401 is inserted into the first concave ring 304 on the side facing the first concave ring 304, forming a ring structure. This can achieve the effect of fixing the cross plug cap 300 in the axial direction of the injection channel 102, preventing the cross plug cap 300 from undergoing longitudinal (axial) displacement in the injection channel 102 when subjected to external forces such as the insertion force of the injection device, internal pressure fluctuations, or transportation shaking. This avoids the change in the position of the cross concave 301 due to the displacement of the cross plug cap 300.

[0034] Please refer to the following: Figure 4 In this embodiment, the aforementioned limiting ring platform 105 is provided with a limiting ring groove 106 surrounding the second opening 104. The first convex ring 303 of the cross plug 300 is inserted into the limiting ring groove 106 on the side facing the limiting ring platform 105. Thus, the limiting ring groove 106 provides axial positioning constraint for the cross plug 300, preventing the cross plug 300 from sliding out of the second opening 104 along the axis of the injection channel 102, ensuring that the cross plug 300 is always between the limiting ring platform 105 and the limiting ring tube 400. Furthermore, the limiting ring groove 106 also assists in installation positioning. During assembly, the limiting ring groove 106 provides a clear insertion alignment reference for the first convex ring 303, enabling the cross plug 300 to be quickly positioned and automatically placed during installation, improving assembly efficiency and consistency, and reducing human error.

[0035] Please refer to the following: Figure 2 and Figure 6 In this embodiment, the outer wall of the oil storage tank 100 is provided with a positioning countersunk hole 107, and the liquid injection plug 200 includes a cover body 201, a sealing plug body 202 and a positioning bolt body 203. The liquid injection plug 200 is an elastic plug 200. The sealing plug body 202 and the positioning bolt body 203 are both disposed on the cover body 201. The sealing plug body 202 is inserted into the first opening 103, and the positioning bolt body 203 is inserted into the positioning countersunk hole 107. The corresponding cover body 201 is tightly attached to the outer wall of the oil storage tank 100.

[0036] In this embodiment, the outer wall of the oil storage tank 100 is provided with a cover groove 108, and the first opening 103 and the positioning sink 107 hole are both provided on the cover groove 108. The cover 201 is adapted to fit into the cover groove 108, so that the liquid injection plug 200 can complete the sealing operation without affecting the overall appearance of the product, thereby improving the integration and aesthetics of the product.

[0037] Specifically, please refer to Figure 7 In this embodiment, the cover 201 includes an adjacent movable cover area 201a and a fixed cover area 201b. The sealing plug 202 is disposed on the movable cover area 201a, so that the first opening 103 of the oil storage tank 100 can be exposed by lifting the movable cover area 201a during the oil filling operation. The positioning bolt 203 is disposed on the fixed cover area 201b, and is used to insert and position in the positioning countersunk hole 107 of the oil storage tank 100 to fix the oil storage tank 100, ensuring that the fixed cover area 201b in the cover 201 always remains stable, thereby playing a structural role of support and positioning. The oil storage tank enclosure structure 20 also includes a mouthpiece assembly 500. The mouthpiece assembly 500 is disposed on the oil storage tank 100 and connects to the oil storage chamber 101. The mouthpiece assembly 500 abuts against the fixed covering area 201b on the side facing away from the cover groove 108, while avoiding the movable covering area 201a on the side facing away from the cover groove 108, so as to avoid interfering with the opening of the movable covering area 201a.

[0038] During the injection process, the user only needs to lift the movable adhesive area 201a of the adhesive cover 201 upwards. At the same time, the sealing plug 202 set on the movable adhesive area 201a can be pulled out from the first opening 103 of the oil storage tank 100. After lifting and pulling, the first opening 103 is exposed for oil injection. After the oil injection is completed, the sealing plug 202 can be reinserted into the first opening 103, and the movable adhesive area 201a will be pressed back into its original position.

[0039] Please see Figure 3 In this embodiment, the mouthpiece assembly 500 includes a housing portion 501 and a tube portion 502 passing through the housing portion 501. The oil storage tank 100 is also provided with an atomizing channel 109. The atomizing channel 109 has a third opening 110 connecting to the outside and a fourth opening 111 connecting to the oil storage chamber 101. The housing portion 501 is disposed on the outer wall of the oil storage tank 100, and the housing portion 501 abuts against the fixed covering area 201b on the side facing away from the cover groove 108, and avoids the movable covering area 201a on the side facing away from the cover groove 108. The tube portion 502 passes through the atomizing channel 109 through the third opening 110 and is connected to the oil storage chamber 101 through the fourth opening 111, thereby realizing the function of guiding and atomizing e-liquid.

[0040] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
