Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and more specifically to an electronic cigarette with a thin-film puncture oil tank assembly structure. Background Technology

[0002] An electronic cigarette is an electronic product that mimics the effects of a cigarette. It uses an atomizing component to vaporize a liquid containing nicotine for the user to inhale. Electronic cigarettes typically consist of a cartridge and a device. The cartridge contains a reservoir to store the nicotine, and the atomizing component, powered by a battery within the device, transforms the liquid nicotine in the cartridge into vapor, giving the user a sensation similar to smoking, allowing them to "exhale clouds of smoke."

[0003] For the export of e-cigarettes, to comply with the regulations of different countries, the e-liquid content in the product must not exceed a specified value. To address this issue, existing products export the e-liquid cartridge in two parts: the e-liquid cup and the atomizer cup. During use, the e-liquid cup is attached to the atomizer cup, and the e-liquid in the cup is introduced into the atomizer assembly through the cup opening to replenish the wicking cotton. To ensure the cleanliness of the e-liquid in the cup, a sealing structure needs to be added to the cup before use. Current methods typically involve adding a filling plug to the cup opening; this plug is removed and discarded before use, and the cup and atomizer cup are then reassembled. This necessitates the additional production of a filling device. This leads to clogged pores and wasted resources. To address this issue, existing sealing structures incorporate a silicone film in the oil supply port. However, due to the high elasticity of the silicone film, ordinary tools often fail to puncture it, requiring a sharper tool to penetrate. After puncturing, the oil cup and atomizing cup are assembled. While this structure avoids resource waste, the punctured film leaves residual edges that can obscure the size of the oil supply port during use, potentially preventing oil supply and impacting user experience, thus hindering product competitiveness. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides an electronic cigarette with a thin-film puncture oil tank assembly structure, which solves the problem of low thin-film puncture efficiency in the assembly structure of the oil cup and atomizing cup of the prior art electronic cigarette.

[0005] This invention discloses an electronic cigarette with a thin-film puncture oil tank assembly structure, comprising a cartridge and a device. The cartridge includes an oil cup and an atomizing cup. The oil cup includes an oil cup shell and an oil tank support, a lower sealing silicone ring, and a side sealing silicone ring disposed within the oil cup shell. The side sealing silicone ring is fitted onto the side of the oil tank support. The oil tank support and the inner wall of the oil cup shell form an oil storage tank. The oil tank support has an oil cup opening, and the lower sealing silicone ring has an oil outlet that mates with the oil cup opening. An integrally formed sealing silicone membrane is disposed within the oil outlet, and the sealing silicone membrane includes a sealing body. The sealing body consists of a sealing film and a sealing part. The sealing part is connected to the inner wall of the oil outlet. The outer periphery of the sealing part is connected to the inner wall of the oil outlet through the sealing film. The thickness of the sealing body is greater than the thickness of the sealing film. A flip positioning part that cooperates with the sealing part is provided in the oil outlet. A piercing guide tube is provided on the upper end face of the atomizing cup. The piercing guide tube can pierce the sealing film and push the sealing part to flip upward so that the sealing part is placed in the flip positioning part. An oil supply channel is provided inside the piercing guide tube. The e-liquid in the oil storage tank can flow into the atomizing cup through the oil supply channel.

[0006] The invention is further improved by making the flipping part a connecting block and the oil sealing part a sealing block. The connecting block and the oil sealing block are integrally formed, and the oil sealing film is arranged in a C-shape around the periphery of the oil sealing block.

[0007] The invention is further improved by making the flipping positioning part a flipping storage groove provided on the inner wall of the oil outlet.

[0008] The invention is further improved by providing an oil outlet notch on the side of the puncture guide cylinder away from the flipping positioning part. The lower end of the oil outlet notch is lower than the upper surface of the oil cup opening, and the oil outlet notch is connected to the oil supply channel.

[0009] The invention is further improved by providing an oil sealing groove on the lower sealing silicone, an oil sealing boss inside the oil sealing groove, an oil outlet in the oil sealing boss, and an oil sealing limiting protrusion that mates with the oil sealing groove on the lower end face of the oil tank bracket. The diameter of the oil sealing boss is larger than that of the oil cup opening, and the oil sealing limiting protrusion is in the oil sealing groove.

[0010] The present invention is further improved by providing an oil sealing protrusion ring around the oil sealing protrusion, and the oil sealing protrusion ring and the oil sealing limiting protrusion ring are interference fit.

[0011] The invention is further improved by providing a mouthpiece on the oil cup shell, and a mouthpiece channel extending inward from the mouthpiece position on the oil cup shell. An air outlet channel that cooperates with the mouthpiece channel is provided on the oil tank support. A mouthpiece oil seal is provided between the mouthpiece channel and the air outlet channel. The mouthpiece oil seal can prevent the e-liquid in the oil tank from leaking from the connection between the mouthpiece channel and the air outlet channel.

[0012] The invention is further improved by providing an air outlet on the lower sealing silicone part that matches the air outlet channel, an air outlet groove on the side of the air outlet, and a connecting cylinder that matches the air outlet groove on the lower end face of the oil tank support. The connecting cylinder and the inner wall of the air outlet groove are interference-fitted.

[0013] The present invention is further improved by providing an atomizing port on the upper surface of the atomizing cup that matches the air outlet, and a sealing wall on the lower surface of the air outlet, wherein the sealing wall is inclined outward from top to bottom, and the sealing wall can match the upper surface of the atomizing cup to improve the sealing between the atomizing port and the air outlet.

[0014] The invention is further improved by providing an oil-guiding arc surface on the upper end face of the oil cup opening, which can promote the oil guiding speed of e-liquid flowing into the oil supply channel.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides an electronic cigarette with a film-piercing oil tank assembly structure. This structure effectively solves the problem of low film piercing efficiency in the assembly structures of the oil cup and atomizing cup in existing electronic cigarettes. Through the cooperation of the sealing body and the sealing film, the thickness of the sealing body is greater than the thickness of the sealing film, effectively weakening the extensibility of the sealing body and concentrating the piercing force at the sealing film, thus effectively reducing the possibility of the sealing film piercing and breaking. Simultaneously, the setting of the flipping positioning part effectively reduces the interference of the sealing part on the assembly process of the piercing guide cylinder, improving the user experience and the product's competitiveness.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1-7 As shown, the present invention discloses an electronic cigarette with a film-pierced oil tank assembly structure, comprising a cartridge and a device 2. The cartridge includes an oil cup 1 and an atomizing cup 3. The oil cup 1 includes an oil cup shell 11, an oil tank support 12 disposed within the oil cup shell 11, and a lower sealing silicone 13. The oil tank support 12 can form an oil storage tank with the inner wall of the oil cup shell 11. An oil cup opening 121 is provided on the oil tank support 12. An oil outlet 131 is provided on the lower sealing silicone 13 to cooperate with the oil cup opening 121. An integrally formed sealing silicone film is disposed within the oil outlet 131. The sealing silicone film includes a sealing body 132 and a sealing film 133. The sealing body 132 includes a flipping part 1321 and a sealing part 1322. The flipping part 1321 is connected to the inner wall of the oil outlet 131. The outer periphery of the sealing part 1322 is connected to the inner wall of the oil outlet 131 through the sealing film 133. The thickness of the sealing body 132 is greater than the thickness of the sealing film 133. The oil outlet 131 is provided with a flipping positioning part 1311 that cooperates with the sealing part 1322. The upper end face of the atomizing cup 3 is provided with a piercing oil guide tube 31. The piercing oil guide tube 31 can pierce the sealing film 133 and push the sealing part 1322 to flip upward so that the sealing part 1322 is placed in the flipping positioning part 1311. The piercing oil guide tube 31 is provided with an oil supply channel 311. The e-liquid in the oil storage tank can flow into the atomizing cup 3 through the oil supply channel 311.

[0022] By combining the sealing body 132 and the sealing film 133, the thickness of the sealing body 132 is greater than that of the sealing film 133, which effectively weakens the extensibility of the sealing body 132 and concentrates the puncture force on the sealing film 133. This effectively increases the possibility of the sealing film 133 being punctured and broken. At the same time, by setting the flipping positioning part 1311, the interference of the sealing part 1322 on the assembly process of the puncture guide cylinder 31 can be effectively reduced, thereby improving the user experience and the competitiveness of the product.

[0023] After the sealing film 133 is broken, the piercing oil guide tube 31 pushes the sealing part 1322 upward to flip it into the flipping positioning part 1311. The piercing oil guide tube 31 continues to be assembled upward until it is assembled into the designated position, thus completing the assembly between the oil cup 1 and the atomizing cup 3.

[0024] The oil inlet of the oil supply channel 311 is located above the puncture guide cylinder 31, which can effectively solve the problem of the residual edge of the film affecting the oil inlet of the oil supply channel 311.

[0025] In this embodiment, the thickness of the sealing body 132 is 0.8 mm, and the thickness of the sealing film 133 is 0.2 mm.

[0026] The oil cup housing 11 is also provided with an oil tank side sealing silicone ring 14. The side of the oil tank bracket 12 is provided with a side sealing oil mounting groove that cooperates with the oil tank side sealing silicone ring 14. The oil tank side sealing silicone ring 14 can be interference-fitted with the inner wall of the oil cup housing 11 to improve the sealing between the oil tank bracket 12 and the inner wall of the oil cup housing 11.

[0027] The flipping part 1321 is a connecting block, and the oil sealing part 1322 is an oil sealing block. The connecting block and the oil sealing block are integrally formed, and the oil sealing film 133 is arranged in a C-shape around the periphery of the oil sealing block.

[0028] By having the sealing film 133 arranged in a C-shape around the outer perimeter of the sealing block, the coverage area of ​​the sealing film 133 can be effectively increased, the puncture force on the sealing film 133 can be increased, and the tear success rate of the sealing film 133 can be improved.

[0029] The upper end of the puncture oil guide cylinder 31 is set in the oil storage tank. This setting can increase the assembly stroke of the puncture oil guide cylinder 31 and improve the tear success rate of the sealing film 133.

[0030] The flipping positioning part 1311 is a flipping storage groove provided on the inner wall of the oil outlet 131. By setting the flipping storage groove, the oil sealing body 132 can be flipped and stored, so as to avoid the oil sealing body 132 interfering with the assembly of the piercing oil guide cylinder 31.

[0031] The puncture guide oil cylinder 31 has an oil outlet notch 312 on the side away from the flip positioning part 1311. The lower end of the oil outlet notch 312 is lower than the upper end face of the oil cup opening 121, and the oil outlet notch 312 is connected to the oil supply channel 311.

[0032] By setting the oil outlet 312, the e-liquid in the oil storage tank can flow into the oil supply channel 311 through the oil outlet 312, avoiding the problem that the e-liquid in the oil storage tank cannot flow out due to the high oil inlet height of the oil supply channel 311. Furthermore, since the lower end of the oil outlet 312 is lower than the upper surface of the oil cup opening 121, the oil inlet position can be lower than the lowest level of the oil storage tank, which can reduce the possibility of e-liquid residue in the oil storage tank.

[0033] By positioning the oil outlet 312 on the side of the puncture guide cylinder 31 away from the flipping positioning part 1311, the possibility of the sealing silicone film blocking the oil outlet 312 can be effectively reduced.

[0034] The lower sealing silicone 13 is provided with multiple mounting holes 134, and the lower end face of the oil tank bracket 12 is provided with multiple mounting posts 122 that cooperate with the mounting holes 134. The lower sealing silicone 13 is installed on the lower end face of the oil tank bracket 12 through the cooperation of the mounting holes 134 and the mounting posts 122.

[0035] The lower sealing silicone 13 is provided with a sealing groove 135, and a sealing boss 136 is provided in the sealing groove 135. The oil outlet 131 is provided in the sealing boss 136. The lower end face of the oil tank bracket 12 is provided with a sealing limiting protrusion 123 that cooperates with the sealing groove 135. The diameter of the sealing boss 136 is larger than the oil cup opening 121, and the sealing limiting protrusion 123 is provided in the sealing groove 135.

[0036] By setting the diameter of the sealing boss 136 to be larger than that of the oil cup opening 121, when the piercing oil guide cylinder 31 is inserted into the oil cup 1, it is possible to prevent the lower sealing silicone 13 from being dragged upward by the piercing oil guide cylinder 31, which would cause the position of the lower sealing silicone 13 to shift and leak oil. At the same time, this setting can also position the lower sealing silicone 13, thereby improving the success rate of the piercing oil guide cylinder 31 piercing the sealing film 133.

[0037] The cooperation between the oil sealing limiting protrusion 123 and the oil sealing groove 135 can improve the accuracy of the assembly position of the lower oil sealing silicone 13 and the oil tank bracket 12.

[0038] An oil-sealing protrusion 136 is provided around the oil-sealing protrusion 1361. The oil-sealing protrusion 1361 and the oil-sealing limiting protrusion 123 are interference-fitted. The interference fit can further improve the sealing performance between the oil-sealing protrusion 136 and the oil cup opening 121, and prevent the e-liquid in the oil storage tank from leaking out from the gap between the oil-sealing protrusion 136 and the oil-sealing limiting protrusion 123.

[0039] A mouthpiece 110 is provided on the oil cup housing 11. A mouthpiece channel 111 is provided inwardly at the position of the mouthpiece 110. An air outlet channel 124 is provided on the oil tank support 12 to cooperate with the mouthpiece channel 111. A mouthpiece oil seal 125 is provided between the mouthpiece channel 111 and the air outlet channel 124.

[0040] By setting the mouthpiece oil sealing component 125, it is possible to prevent the e-liquid in the oil storage tank from leaking from the connection between the mouthpiece channel 111 and the air outlet channel 124.

[0041] The lower sealing silicone rubber 13 piece is provided with an air outlet 137 that mates with the air outlet channel 124. An air outlet groove 138 is provided on the side of the air outlet 137. A connecting cylinder 126 that mates with the air outlet groove 138 is provided on the lower end face of the oil tank bracket 12. The connecting cylinder 126 and the inner wall of the air outlet groove 138 are interference fit.

[0042] By using an interference fit, the precise installation and matching of the lower sealing silicone 13 pieces and the oil tank bracket 12 can be improved, while the sealing performance between the air outlet 137 and the air outlet channel 124 can also be improved.

[0043] The upper end face of the atomizing cup 3 is provided with an atomizing port 32 that matches the air outlet 137. The lower end face of the air outlet 137 is provided with a sealing wall 138, and the sealing wall 138 is inclined outward from top to bottom.

[0044] With the setting of the sealing wall 138, after the oil cup 1 and the atomizing cup 3 are assembled, the sealing wall 138 is compressed and deformed upward, filling the gap between the atomizing port 32 and the air outlet 137, which can effectively improve the sealing performance between the atomizing port 32 and the air outlet 137.

[0045] An oil-guiding arc surface 127 is provided on the upper end face of the oil cup opening 121. Through the setting of the oil-guiding arc surface 127, the e-liquid can be efficiently guided into the oil supply channel 311, which increases the oil guiding speed to a certain extent.

[0046] As can be seen from the above, the beneficial effects of the present invention are as follows: by adopting its structure, it can effectively solve the problem of low film puncture efficiency in the assembly structure of the oil cup 1 and atomizing cup 3 of electronic cigarettes in the prior art. Through the cooperation of the sealing body 132 and the sealing film 133, the thickness of the sealing body 132 is greater than the thickness of the sealing film 133, which effectively weakens the extensibility of the sealing body 132 and concentrates the puncture force on the sealing film 133, which can effectively increase the possibility of puncture and breakage of the sealing film 133. At the same time, by setting the flipping positioning part 1311, the interference of the sealing part 1322 on the assembly process of the puncture guide cylinder 31 can be effectively reduced, thereby improving the user experience and the competitiveness of the product.

[0047] The specific embodiments described above are preferred embodiments of the present invention and are not intended to limit the specific scope of the present invention. The scope of the present invention includes, but is not limited to, these specific embodiments. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
