[0029] like Figures 1 to 6 As shown, this application provides an expandable capacity electronic cigarette. The expandable capacity electronic cigarette includes an electronic cigarette body 100 and an expansion component 200. The electronic cigarette body 100 includes a first oil storage shell 110, a connecting tube 120, and an atomizer 130. The first oil storage shell 110 includes a first oil storage space 111 for storing e-liquid. The connecting tube 120 is a hollow tube, disposed on the surface of the first oil storage shell 110 and communicating with the first oil storage space 111. The atomizer 130 is disposed in the first oil storage space 111 to atomize the e-liquid in the first oil storage space 111. The expansion component 200 includes a second oil storage shell 210, which includes a second oil storage space 211 for storing e-liquid. The second oil storage shell 210 has a connecting hole 212 that connects the second oil storage space 211 to the outside. When it is necessary to expand the capacity, the connecting pipe 120 is extended into the second oil storage space 211 through the connecting hole 212, so that the first oil storage space 111 and the second oil storage space 211 are connected.

[0030] In one specific embodiment, the electronic cigarette body 100 is the basic part used by the user daily. The first oil storage shell 110 is usually made of a material with certain strength and corrosion resistance. The first oil storage shell 110 has a first oil storage space 111 that is approximately rectangular in shape. The first oil storage space 111 is provided with a first oil storage cotton 116 that matches the first oil storage space 111. The e-liquid in the first oil storage space 111 is stored through the first oil storage cotton 116. The first oil storage space 111 is the initial storage area for e-liquid, and the size of the first oil storage space 111 determines the e-liquid capacity of the electronic cigarette in its unexpanded state.

[0031] The connecting pipe 120 is cylindrical and serves as a channel connecting the first oil storage space 111 to the outside. Due to its hollow structure, it enables the circulation of e-liquid.

[0032] The atomizer 130 is a key component of the electronic cigarette. Its function is to convert liquid e-liquid into inhalable vapor, generally using the technology of heating the e-liquid with a heating wire. The atomizer 130 passes through the center of the first oil reservoir 116 and is in close contact with it. The atomizer 130 has a vapor channel in its center, into which the atomized e-liquid enters. The first oil reservoir shell 110 has a vapor outlet 112 corresponding to the vapor channel. The electronic cigarette body 100 also includes a mouthpiece 140, which is fixedly assembled to the first oil reservoir shell 110. The mouthpiece 140 is connected to the vapor outlet 112, allowing the user to inhale the atomized e-liquid through the mouthpiece 140.

[0033] The second oil storage space 211 inside the second oil storage shell 210 is used to store additional e-liquid. The second oil storage space 211 is equipped with a matching second oil storage cotton 216, through which e-liquid is stored. When the user has an expansion need, the connecting tube 120 on the electronic cigarette body 100 can be inserted into the second oil storage space 211 through the connecting hole 212 on the second oil storage shell 210, thereby connecting the first oil storage space 111 and the second oil storage space 211 to each other, so as to replenish e-liquid from the second oil storage space 211 to the first oil storage space 111, thereby expanding the overall e-liquid capacity of the electronic cigarette.

[0034] like Figure 6 As shown, the expansion assembly 200 also includes a first sealing plug 220. The surface of the second oil storage shell 210 is provided with a first annular wall 213 at the position corresponding to the connecting hole 212. The first annular wall 213 surrounds and forms an installation groove. The first sealing plug 220 is fixedly installed in the installation groove so as to seal the connecting hole 212.

[0035] In one specific embodiment, the first sealing plug 220 plays a crucial sealing role in the expansion assembly 200. The first sealing plug 220 is generally made of materials with good sealing properties, such as rubber or silicone. The first annular wall 213 on the surface of the second oil storage shell 210 is a raised structure built around the connecting hole 212. The first annular wall 213 forms an installation groove, which provides an installation position for the first sealing plug 220. When no expansion operation is performed, the first sealing plug 220 is tightly installed in the installation groove, completely sealing the connecting hole 212. This is to ensure the airtightness of the second oil storage space 211, preventing e-liquid leakage from the connecting hole 212, and also preventing external impurities from entering the second oil storage space 211 and contaminating the e-liquid.

[0036] like Figure 2 As shown, the end of the connecting pipe 120 away from the first oil storage shell 110 is spiked to facilitate piercing the first sealing plug 220.

[0037] In one specific embodiment, the connecting tube 120, as a crucial component connecting the first oil storage space 111 of the electronic cigarette body 100 and the second oil storage space 211 of the expansion assembly 200, has a spike-like end away from the first oil storage shell 110. This spike-like structure possesses sufficient hardness and sharpness, allowing the user to directly align the connecting tube 120 with the connecting hole 212 of the second oil storage shell 210 when performing an expansion operation. Facing the first sealing plug 220 installed at the connecting hole 212, the user does not need to manually remove the first sealing plug 220 first; instead, the user can directly pierce the first sealing plug 220 with the spiked end. This design simplifies the expansion operation process and avoids potential sealing problems in the second oil storage space 211 caused by the user losing the first sealing plug 220 during operation.

[0038] like Figure 6 As shown, the expansion assembly 200 also includes a second sealing plug 230. The second oil storage shell 210 has a first opening 214 on one side. The second sealing plug 230 matches the first opening 214 and is embedded in the first opening 214, thereby sealing the second oil storage space 211.

[0039] In one specific embodiment, on the second oil storage shell 210 of the expansion assembly 200, the first opening 214 is a relatively large opening structure, typically located on one side of the second oil storage shell 210. The first opening 214 is used to install the second oil storage cotton 216. The second sealing plug 230 is a sealing component designed for the first opening 214, and its material is generally rubber or silicone with good sealing performance. The shape and size of the second sealing plug 230 are precisely matched with the first opening 214. During the production process, by embedding the second sealing plug 230 into the first opening 214, a tight fit can be achieved, thereby effectively sealing the second oil storage space 211 and preventing e-liquid leakage and the entry of external impurities.

[0040] like Figure 6 As shown, the expansion component 200 also includes a base 240, a first snap-fit ​​groove 215 is provided at the first opening 214, and the base 240 is provided with a first protrusion 241. The first protrusion 241 is embedded in the first snap-fit ​​groove 215, so that the base 240 is fixedly installed at the first opening 214.

[0041] In one specific embodiment, the base 240 is an important component in the structural design of the expansion assembly 200. The first snap-fit ​​groove 215 at the first opening 214 of the second oil reservoir 210 consists of two groove structures with a specific shape and depth, designed near the edge of the first opening 214. Each end of the base 240 has a first protrusion 241, the shape and size of which precisely match the first snap-fit ​​groove 215. When installing the base 240, the first protrusion 241 on the base 240 is aligned with the first snap-fit ​​groove 215 at the first opening 214, and then the first protrusion 241 is forcefully inserted into the first snap-fit ​​groove 215. This snap-fit ​​method securely fixes the base 240 at the first opening 214. The base 240 not only provides support and protection for the second oil reservoir 210 but also serves to connect other components or facilitate handheld operation during use.

[0042] like Figure 6 As shown, the base 240 is provided with a receiving groove 242, the shape of which matches the shape of the second sealing plug 230, and a portion of the second sealing plug 230 is embedded in the receiving groove 242.

[0043] In one specific embodiment, in the design of the base 240, the receiving groove 242 is a structure provided for accommodating the second sealing plug 230. The shape of the receiving groove 242 is precisely designed according to the shape of the second sealing plug 230. When the base 240 is fixedly installed with the second oil storage housing 210, a portion of the second sealing plug 230 is embedded in the receiving groove 242 to enhance the sealing effect of the second sealing plug.

[0044] like Figure 3As shown, the expandable capacity electronic cigarette also includes a protective shell 300, the protective shell 300 is provided with a support plate 310, the support plate 310 is provided with a second protrusion, and the base 240 is provided with a corresponding second snap-fit ​​groove 243, so that the expansion component 200 can be fixedly installed on the support plate 310 when needed.

[0045] In one specific embodiment, in the overall structure of the expandable capacity electronic cigarette, the protective shell 300 mainly serves to protect the electronic cigarette body 100 and to install the expansion component 200. The protective shell 300 is typically made of plastic with a certain strength and flexibility. The support plate 310 provided on the protective shell 300 is an arc-shaped plate structure with a curvature. The support plate 310 provides a support platform for the installation of the expansion component 200, and the arc-shaped structure of the support plate 310 makes the installation of the expansion component 200 more stable. A second protrusion is provided at the center of the surface of the support plate 310, and a second snap-fit ​​groove 243 is provided on the side of the base 240 away from the second oil storage shell 210. The shape and size of the second snap-fit ​​groove 243 are precisely adapted to the second protrusion. When the user needs to expand the capacity, the second snap-fit ​​slot 243 on the base 240 is aligned with the second protrusion on the support plate 310, and then the second protrusion is forcefully inserted into the second snap-fit ​​slot 243. Through this snap-fit ​​method, the expansion component 200 can be firmly fixed on the support plate 310 of the protective shell 300, so that the expansion component 200 and the electronic cigarette body 100 form a unified whole.

[0046] like Figure 4 As shown, the surface of the first oil storage shell 110 is provided with a second annular wall 113. The diameter of the first annular wall 213 is smaller than the diameter of the second annular wall 113, so that when the expansion assembly 200 is installed, the first annular wall 213 is embedded in the second annular wall 113.

[0047] In one specific embodiment, the second annular wall 113 on the surface of the first oil storage shell 110 is a protruding structure centered on the connecting pipe 120. The diameter of the first annular wall 213 on the second oil storage shell 210 corresponding to the connecting hole 212 is smaller than the diameter of the second annular wall 113. When the user performs an expansion operation, the first annular wall 213 on the second oil storage shell 210 is aligned with the second annular wall 113 on the first oil storage shell 110, and then the first annular wall 213 is embedded into the second annular wall 113. This nested structural design, on the one hand, helps to accurately position the connecting pipe 120 and the connecting hole 212 when installing the expansion assembly 200, ensuring that the connecting pipe 120 can be smoothly inserted into the connecting hole 212 to achieve communication between the two oil storage spaces; on the other hand, it also enhances the stability and sealing of the connection between the two oil storage spaces to a certain extent.

[0048] like Figure 4As shown, a sealing ring 114 is embedded in the second annular wall 113. When the first annular wall 213 is embedded in the second annular wall 113, the first annular wall 213 and the second annular wall 113 clamp the sealing ring 114.

[0049] In one specific embodiment, in the structure of the second annular wall 113 of the first oil storage shell 110, the sealing ring 114 is an important sealing component. The sealing ring 114 is typically made of a material with good elasticity and sealing properties, such as rubber or silicone. The sealing ring 114 is embedded in the groove enclosed by the second annular wall 113. When the expansion assembly 200 is installed, i.e., when the first annular wall 213 is embedded into the second annular wall 113, the first annular wall 213 and the second annular wall 113 tightly clamp the sealing ring 114 in the middle. The presence of the sealing ring 114 further enhances the sealing performance of the connection between the two oil storage spaces, preventing e-liquid from leaking out from the connection between the first annular wall 213 and the second annular wall 113.

[0050] like Figure 4 As shown, the expandable capacity electronic cigarette also includes a sealing strip 150. When the expansion component 200 is not required, the sealing strip 150 is embedded in the connecting tube 120 to prevent e-liquid leakage.

[0051] In one specific embodiment, the shape of the sealing strip 150 matches the hollow portion of the connecting pipe 120. The connecting pipe 120 serves as a channel in the electronic cigarette body 100 connecting the first oil storage space 111 to the outside (connecting to the second oil storage space 211 in an expansion scenario). When no expansion operation is performed, it is in an idle state. At this time, embedding the sealing strip 150 into the connecting pipe 120 can effectively seal the connecting pipe 120. Due to the close contact between the sealing strip 150 and the inner wall of the connecting pipe 120, a reliable barrier can be formed to prevent the e-liquid in the first oil storage space 111 from leaking from the connecting pipe 120.

[0052] like Figure 3 and Figure 4 As shown, the expandable capacity electronic cigarette also includes a battery compartment 400, which includes a body 410 and a third sealing plug 420. The body 410 has a third opening, and the third sealing plug 420 is inserted into the third opening to form a relatively enclosed space inside the body 410. The battery 430 is disposed inside the body 410. The first oil storage shell 110 also has a second opening 115 for installing components such as the first oil storage cotton 116. The expandable capacity electronic cigarette also includes a fourth sealing plug 160, which is integrally formed with the third sealing plug 420 and is inserted into the second opening 115 to prevent e-liquid from leaking from the second opening 115. The atomizing tube passes through the third sealing plug 420 and the fourth sealing plug 160, and is electrically connected to the battery 430.

[0053] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
