Description

Technical Field

[0001] The present invention relates to the field of electronic cigarettes, and particularly to an electronic cigarette adopting a silicone-based multiple anti-leakage liquid structure. Background Art

[0002] An electronic cigarette is an electronic product that imitates a cigarette, having the same appearance, smoke, taste and feeling as a cigarette, and even having many more flavors than ordinary cigarettes. It is a product that allows users to inhale by atomizing nicotine and the like into steam. Generally, an electronic cigarette mainly consists of a cigarette tube for containing nicotine solution, an evaporation device and a battery. The atomizer is powered by a battery rod and can convert the liquid nicotine in the cartridge into mist, so that the user has a feeling similar to smoking when inhaling, realizing "puffing clouds and exhaling mists". It can even add various flavoring spices such as chocolate and mint into the cigarette tube according to personal preferences.

[0003] Currently, for the electronic cigarette cartridges on the market, the best taste is generally achieved by storing oil in an oil chamber. During the atomization process of the e-liquid, the oil flows down from the top. Since the atomization carriers are all porous carriers and their oil-locking capabilities are different, the atomization carriers are prone to leaking oil and damaging the internal electronic components of the electronic cigarette, resulting in a poor user experience of the electronic cigarette.

Detailed implementation mode

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] As Figure 1As shown in the figure, the present invention provides an electronic cigarette with a silicone rubber multi-layer anti-leakage structure, which includes a detachable electronic cigarette body 1 and an electronic cigarette cartridge 2. The electronic cigarette body includes a housing 11, a power source 12 and a central control circuit board 13 arranged in the housing 11. The housing 11 is provided with an air inlet hole. The power source 12 is electrically connected to the central control circuit board 13. An air inlet chamber 14 is provided at the connection between the electronic cigarette body 1 and the electronic cigarette cartridge 2. The air inlet chamber 14 is communicated with the air inlet hole. The electronic cigarette cartridge 2 includes a mouthpiece 21, an e-liquid atomization chamber 22 and a fuel supply chamber 23 integrally formed with the electronic cigarette cartridge housing. The mouthpiece 21 and the e-liquid atomization chamber 22 are respectively arranged at both ends of the fuel supply chamber 23. A smoke airway 24 is provided between the mouthpiece 21 and the e-liquid atomization chamber 22. The fuel supply chamber 23 is provided with an oil inlet hole communicated with the e-liquid atomization chamber 22. An atomization carrier 221, a heating wire 222 and a power receiving electrode 223 are arranged in the e-liquid atomization chamber 22. The atomization carrier 221 is a strip-shaped cotton core atomizer. The main body of the heating wire 222 is wound inside the cotton core atomizer. The end pin of the heating wire 222 extends to the power receiving electrode 223 and is electrically connected to the power receiving electrode 223. A silicone rubber plug 141 is provided at one end of the air inlet chamber 14 in the electronic cigarette body 1. A first oil-absorbing cotton 142 is provided at one end of the air inlet chamber 14 in the electronic cigarette cartridge 2. The first oil-absorbing cotton 142 is closely arranged against the power receiving electrode 223. A clamping groove is opened above the silicone rubber plug 141 for fixing the first oil-absorbing cotton 142. By arranging the first oil-absorbing cotton 142 in the electronic cigarette, the storage space for e-liquid and condensate in the electronic cigarette is increased. By arranging the silicone rubber plug 141 in the electronic cigarette, the sealing performance of the electronic cigarette is enhanced, and the problem that the atomization carrier of the electronic cigarette cartridge in the current market is prone to oil leakage and damage to the internal electronic components of the electronic cigarette, resulting in a poor user experience of the electronic cigarette, is solved. At the same time, when assembling the silicone rubber plug 141, it can be first installed into the electronic cigarette body, and then the electronic cigarette cartridge is pressed down for assembly. Dozens or hundreds of them can be assembled at the same time, greatly improving the assembly production efficiency of the electronic cigarette.

[0021] As Figure 1 shown, a metal pipe is sleeved outside the cotton core atomizer. First-stage anti-leakage silicone rubber rings with interference fit are arranged inside both ends of the metal pipe. Clamping groove rings are arranged at the joints between the inner walls of both ends of the metal pipe and the first-stage anti-leakage silicone rubber rings. The heating wire 222 passes through the first-stage anti-leakage silicone rubber ring and is electrically connected to the power receiving electrode 223. Two small holes are opened in the first-stage anti-leakage silicone rubber ring, through which the heating wire 222 can pass, preventing liquid from flowing down along the heating wire 222. At the same time, the first-stage anti-leakage silicone rubber ring has an interference fit with the inner wall of the metal pipe, blocking the drainage of the inner wall of the metal pipe. It can also be used to position the oil inlet hole to align with the position of the heating wire 222, preventing problems such as unsmooth air passage and charring caused by the heating wire 222 being pushed too far inside the metal pipe.

[0022] As shown Figure 1 in the figure, a second leak-proof silica gel groove 143 is provided below the place where the heating wire 222 extends out of the metal pipe. A clamping protrusion is provided at the bottom of the second leak-proof silica gel groove 143. The clamping protrusion is clamped into the first oil-absorbing cotton 142. The side of the second leak-proof silica gel groove 143 is closely clamped into a groove on one side of the power-receiving electrode 223. The clamping protrusion at the bottom of the second leak-proof silica gel groove 143 is used to position the first oil-absorbing cotton 142 below, and the clamping protrusion is reversely clamped into the inside of the first oil-absorbing cotton 142 to prevent the first oil-absorbing cotton 142 from sliding; the side of the second leak-proof silica gel groove 143 can also be used to fix the power-receiving electrode 223 to make the power-receiving electrode 223 in close contact with the heating wire 222.

[0023] As shown Figure 1 in the figure, a silica gel ring clamping groove 151 and a circuit board clamping groove 131 are provided on the inner wall of the bottom end housing of the electronic cigarette body 1. A third leak-proof silica gel ring 15 is provided at the bottom end of the electronic cigarette body 1. The outer side of the third leak-proof silica gel ring 15 is clamped into the silica gel ring clamping groove 151, and the outer end of the central control circuit board 13 is clamped into the circuit board clamping groove 131. Raised leak-proof columns 152 are provided at both ends of the top of the third leak-proof silica gel ring 15. By providing a silica gel ring clamping groove 151 on the inner wall of the bottom end housing of the electronic cigarette body, it is possible to prevent liquid leakage from seeping into the central control circuit board and damaging the electronic cigarette; by providing a circuit board clamping groove 131 on the inner wall of the bottom end housing of the electronic cigarette body, the central control circuit board is limited to prevent the central control circuit board from loosening, shaking, or falling off, improving the stability of the internal component structure of the electronic cigarette, and at the same time solving the problem that the glue used to paste the central control circuit board on the market will cause corrosion and damage to the circuit board.

[0024] As shown Figure 1 in the figure, a breathing lamp 16 and a light-transmitting body 17 are further provided at the bottom of the electronic cigarette body 1. The light-transmitting body 17 surrounds the breathing lamp 16. The outer side of the light-transmitting body 17 is connected to the outer shell of the electronic cigarette body 1, which can control the light source within the light-transmitting body, improve the brightness, and make it easier for users to judge the operating state of the electronic cigarette. At the same time, it can also form a beautiful lighting pattern.

[0025] As shown Figure 1As shown, an air intake channel 224 and an oil-gas separation plate 225 are further provided in the e-liquid atomization chamber 22. The air intake channel 224 and the power receiving electrode 225 are both provided at the end of the e-liquid atomization chamber 22. The power receiving electrode 223 is a T-shaped electrode. There are at least two contact points where the power receiving electrode 223 is electrically connected to the heating wire 222. The power receiving electrode 223 is injection-molded in the mold at the end of the e-liquid atomization chamber 22. The power receiving electrode 223 is non-removable. The atomization carrier 221 is communicated with the oil inlet hole. The oil-gas separation plate 225 is arranged between the atomization carrier 221 and the smoke airway 24. By embedding a T-shaped power receiving electrode in the e-cigarette cartridge by means of in-mold injection, the convex clamping position beside the T-shaped power receiving electrode makes the structure more stable and not easy to shake. The in-mold injection power receiving electrode has better sealing performance at the joint between the power receiving electrode and the e-liquid atomization chamber than the power receiving electrode embedded by riveting or other methods, preventing e-liquid from leaking out from the edge of the power receiving electrode, and solving the problem that the atomization carrier on the current market is prone to oil leakage and damage to the electronic components inside the e-cigarette.

[0026] As Figure 1 shown, a plurality of S-shaped airways 226, atomization smoke outlets and a fourth anti-leakage silicone rubber seal ring 227 are further provided in the e-liquid atomization chamber 22. The S-shaped airways 226 are arranged between the cotton core atomizer and the smoke airway 24. The atomization smoke outlets communicate the e-liquid atomization chamber 22 with the smoke airway 24. The fourth anti-leakage silicone rubber seal ring 227 is arranged between the cotton core atomizer and the outer shell of the e-cigarette cartridge 2. The S-shaped airways increase the storage space for e-liquid and condensate between the cotton core atomizer in the e-liquid atomization chamber 22 and the smoke airway 24, can store more residual e-liquid and condensate, and can also play a role in ventilation. The fourth anti-leakage silicone rubber seal ring 227 enhances the sealing performance in the e-liquid atomization chamber 22, preventing residual e-liquid and condensate from flowing into the e-cigarette main body through the air intake channel 224.

[0027] As Figure 1As shown, the smoke airway 24 includes a first smoke channel 241 at one end of the mouthpiece 21, a second smoke channel 242 near the e-liquid atomization chamber, and a smoke airway flange 243. The first smoke channel 241 communicates with the second smoke channel 242 through the smoke airway flange 243. The diameter of the first smoke channel 241 is smaller than that of the second smoke channel 242, which is not easy to generate condensate, and it is not easy for the user to draw e-liquid when using. The e-liquid cartridge 2 is also provided with a detachable mouthpiece silicone plug and an air inlet channel silicone plug. The mouthpiece silicone plug is in interference fit with the mouthpiece 21, and the air inlet channel silicone plug is in interference fit with the air inlet channel 224, making the seal of the e-liquid cartridge better. The e-liquid in the e-liquid cartridge is not easy to flow out during transportation. The air inlet channel silicone plug is inserted into the e-liquid cartridge 2 from the air inlet channel 224 through a set of breakable whiskers. Breaking the whiskers makes the air inlet channel silicone plug fit more tightly with the air inlet channel 221, further improving the seal. By providing a first smoke channel with a diameter smaller than that of the second smoke channel in the e-liquid cartridge, it is not easy to generate condensate, and it is not easy for the user to draw e-liquid when using.

[0028] As Figure 1 shown, a second oil-absorbing cotton 2411 is further provided in the first smoke channel 241, and the second oil-absorbing cotton 2411 is in interference fit with the inner wall of the first smoke channel 241. The second oil-absorbing cotton 2411 increases the storage space for e-liquid and condensate in the e-cigarette, and solves the problem that the atomization carrier of the e-liquid cartridge on the current market is prone to oil leakage and damage to the internal electronic components of the e-cigarette, resulting in a poor user experience of the e-cigarette.

[0029] As Figure 1 shown, two first magnetic rings are provided at one end of the e-cigarette body 1 where the air inlet chamber 14 is located. A second magnetic ring that cooperates with the first magnetic ring is provided at one end of the air inlet chamber 14 where the e-liquid cartridge 2 is located. The second magnetic ring is arranged around the power receiving electrode 223 at the end inside the e-liquid atomization chamber 22.

[0030] As can be seen from the above, an electronic cigarette with a multiple anti-leakage liquid structure arranged by silica gel provided by the present invention increases the storage space of e-liquid and condensate in the electronic cigarette by setting a first absorbent cotton, a silica gel plug, a second absorbent cotton, a first anti-leakage silica gel ring, a second anti-leakage silica gel groove, a third anti-leakage silica gel ring and a fourth anti-leakage silica gel sealing ring in the electronic cigarette, and solves the problem that the atomization carrier of the electronic cigarette cartridge on the current market is prone to oil leakage and damage the internal electronic components of the electronic cigarette, resulting in a poor user experience of the electronic cigarette. At the same time, when assembling the silica gel plug 141, it can be first inserted into the main body of the electronic cigarette, and then the electronic cigarette cartridge is pressed down for assembly. Dozens or hundreds of them can be assembled at the same time, greatly improving the assembly production efficiency of the electronic cigarette. By providing a silica gel ring clamping groove and a circuit board clamping groove on the inner wall of the bottom shell of the main body of the electronic cigarette, the central control circuit board is limited to prevent the central control circuit board from loosening, shaking and falling off, improving the stability of the internal component structure of the electronic cigarette, and at the same time solving the problem that the use of glue to paste the central control circuit board on the market will cause corrosion and damage to the circuit board; by setting a breathing lamp and a light-transmitting body that cooperate with each other, the light source can be controlled within the light-transmitting body, improving the brightness and making it easier to judge the operating state of the electronic cigarette, and at the same time forming a beautiful lighting pattern.

[0031] It also arranges a cotton core atomizer in the electronic cigarette cartridge. The cotton core atomizer with fluffy pores and strong adsorption makes the e-liquid atomize more fully and is not prone to oil leakage, and has a better heat dissipation effect; by arranging a plurality of S-shaped air channels in the electronic cigarette cartridge, the storage space for e-liquid and condensate between the cotton core atomizer in the e-liquid atomization chamber and the smoke air channel is increased, and more residual e-liquid and condensate can be stored. At the same time, it can also play a role in ventilation to prevent the residual e-liquid and condensate from flowing into the main body of the electronic cigarette through the air intake channel; by arranging a first smoke channel with a diameter smaller than that of the second smoke channel in the electronic cigarette cartridge, it is not easy to generate condensate, and it is not easy for users to draw e-liquid when using; by embedding a T-shaped power receiving electrode in the electronic cigarette cartridge by means of in-mold injection, the convex clamping position beside the T-shaped power receiving electrode makes the structure more stable and not easy to shake. The in-mold injection power receiving electrode has better sealing performance at the joint between the power receiving electrode and the e-liquid atomization chamber than the power receiving electrode embedded by riveting or other methods, preventing e-liquid from seeping out from the edge of the power receiving electrode, and solving the problem that the atomization carrier on the current market is prone to oil leakage and damage the internal electronic components of the electronic cigarette. It also arranges a T-shaped power receiving electrode in the electronic cigarette cartridge. The power receiving electrode is in two-point contact with the heating wire, increasing the contact area between the power receiving electrode and the heating wire, making the heating wire heat more stably, and improving the user experience of the electronic cigarette.

[0032] The above-mentioned specific implementation manners are the preferred implementation manners of the present invention, and do not limit the specific implementation scope of the present invention by this. The scope of the present invention includes but is not limited to this specific implementation manner. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
