Description

Technical Field

[0001] The present disclosure relates to the field of electronic cigarettes, and particularly to an electronic cigarette cartridge and an electronic cigarette with a child lock valve provided at the oil injection port. Background Art

[0002] With the rapid development of electronic cigarette technology, there are various types of electronic cigarette products, including refillable electronic cigarettes and integrated electronic cigarettes. Among them, the refillable ones include disposable cartridges and refillable cartridges, and the integrated electronic cigarettes include clear oil types and those using an integrated oil storage cotton for oil storage. The cartridges of refillable electronic cigarettes usually have a small oil storage capacity. To avoid waste of resources, refillable cartridges are usually designed. After the e-liquid in the cartridge is consumed, it can be refilled and used again. The refillable cartridge is provided with an oil injection port, and the oil injection port is provided with a sealing plug. For the existing electronic cigarette cartridges with an oil injection port and a sealing plug, usually, after the sealing plug is pulled out, the e-liquid can be poured out. This design has the risk that children may accidentally pull out the sealing plug and pour out the e-liquid or ingest the e-liquid. Therefore, it is necessary to further optimize the design of the refillable electronic cigarette cartridge to solve the above problems. Summary of the Utility Model

[0003] In view of this, the present disclosure provides an electronic cigarette cartridge and an electronic cigarette with a child lock valve provided at the oil injection port. The electronic cigarette cartridge designed by this solution can prevent children from accidentally opening the mouthpiece and directly pouring out the e-liquid or ingesting the e-liquid, thus achieving the purpose of child lock.

[0004] The technical solution of the present application is to provide an electronic cigarette cartridge with a child lock valve provided at the oil injection port, which includes a cartridge housing, an atomization core, a mouthpiece, and an oil seal base. The cartridge housing is a housing with an open bottom and a hollow oil storage cavity inside. The upper end of the cartridge housing is provided with a docking end, and the top surface of the docking end is provided with a smoke output hole and an oil injection hole. Inside the cartridge housing corresponding to the oil injection hole, there is a silicone child lock valve for sealing the oil injection hole. The upper end of the atomization core is inserted into the smoke output hole, and the lower end is connected to the oil seal base. The oil seal base is provided with an air inlet hole, and the mouthpiece is sleeved on the docking end of the cartridge housing.

[0005] Further, the upper end of the mouthpiece is provided with a suction port, and the suction port extends along the inside of the mouthpiece to form a flared opening that is wider at the top and narrower at the bottom. The suction port and the inner wall of the mouthpiece form an inner cavity of the mouthpiece. A sealing silicone member is embedded in the inner cavity of the mouthpiece. The sealing silicone member is provided with a through hole corresponding to the suction port. A first sealing convex ring is provided around the through hole, and a second sealing convex ring corresponding to covering the periphery of the oil injection hole is also provided.

[0006] Further, the lower end of the mouthpiece is snap-fitted with the side wall of the docking end of the cartridge housing.

[0007] Furthermore, the suction nozzle is made of food-grade plastic material. The sealing silicone part and the suction nozzle are two separate components, or the sealing silicone part and the suction nozzle are made into an integral part by the overmolding process.

[0008] Furthermore, the silicone child lock valve is a hollow cylindrical main body. On one side of the hollow cylindrical main body, there is a first connecting part protruding outward. On the outside of the first connecting part, there is a second connecting part extending upward. Inside the second connecting part, a curved notch is formed with the outer wall of the hollow cylindrical main body. On the outer side of the upper end of the second connecting part, there is a baffle part extending obliquely upward. The hollow cylindrical main body, the first connecting part, the second connecting part, and the baffle part are integrally formed.

[0009] Furthermore, the atomization core includes an atomization core outer cover, outer wrapping cotton, a heating wire, inner wrapping cotton, and a connecting bracket. The upper end of the atomization core outer cover is a hollow cylindrical insertion part. The side wall of the cover body of the atomization core outer cover is provided with oil guiding holes. The connecting bracket includes a circular base and a U-shaped clamping wall. After the inner wrapping cotton is sleeved outside the heating wire, the whole is sleeved inside the clamping wall. The outer wrapping cotton is sleeved outside the clamping wall, and then the whole is inserted into the atomization core outer cover. A hollow insulating silicone with a through hole in the middle is sleeved at the bottom of the circular base. The electrode pins of the heating wire pass through the insulating silicone.

[0010] Furthermore, the oil seal base includes a bottom cover and an oil cavity sealing silicone. The side wall of the oil cavity sealing silicone is provided with a sealing convex ring for sealing the inner wall of the cartridge shell. The oil cavity sealing silicone is provided with a through hole for inserting the connecting bracket. The bottom cover includes a cover plate part and a bottom cover side wall part. A groove is formed inside the bottom cover side wall part. Inside the groove, there is a first installation position for installing electrode terminals and a second installation position for embedding a magnet. The air inlet hole is arranged at the bottom of the cover plate. The bottom cover side wall part is clamped with the cartridge shell.

[0011] Furthermore, the air inlet hole is provided with an air inlet hole wall extending upward inside the bottom of the cover plate. An adsorption cotton block is arranged in the groove avoiding the air inlet hole wall, the first installation position, and the second installation position.

[0012] The electronic cigarette cartridge designed by this technical solution has the beneficial effect that the inside of the cartridge housing of the electronic cigarette cartridge serves as an oil storage cavity. The cartridge housing and the mouthpiece are designed as two components. There is an oil injection hole at the upper end of the cartridge housing, and a silicone child lock valve is arranged in the oil injection hole. When refueling is needed, the mouthpiece is separated from the cartridge housing, and then the oil bottle nozzle is inserted into the oil injection hole to push open the silicone child lock valve to achieve refueling. After refueling is completed, the oil bottle nozzle is pulled out, and the silicone child lock valve automatically seals the oil injection hole again due to the elastic deformation of the silicone. The setting of the silicone child lock valve ensures that when the electronic cigarette cartridge is accidentally pulled out by a child, the e-liquid will not pour out from the oil injection hole. Moreover, since the oil injection hole is relatively small, a child's finger cannot be inserted, avoiding the risk of a child accidentally ingesting the e-liquid when playing with it.

[0013] On the other hand, the silicone child lock valve at the oil injection port of the electronic cigarette cartridge designed by this technical solution and the sealing silicone part in the mouthpiece are used to seal the upper end face of the cartridge housing and seal the upper edge of the oil injection port. Compared with the existing structure that uses a sealing plug to block the oil injection port, this oil injection port sealing structure is more convenient for refueling because it is more difficult to pull out the sealing plug when refueling is needed.

[0019] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall also fall within the scope of protection of the present disclosure.

[0020] Please refer to Figures 1 to 3, an embodiment of an e-cigarette cartridge with a child lock valve at the filling port disclosed in this technical solution. The e-cigarette cartridge includes a cartridge housing 1, an atomization core 2, a mouthpiece 3, and an oil seal base 4. It is characterized in that the cartridge housing 1 has an open bottom and a hollow oil storage cavity inside. The upper end of the cartridge housing 1 is provided with a docking end. The top surface of the docking end is provided with a smoke output hole 101 and a filling hole 102. Inside the cartridge housing 1 corresponding to the filling hole 102, there is a silicone child lock valve 5 for sealing the filling hole 102. The upper end of the atomization core 2 is inserted into the smoke output hole 101, and the lower end of the atomization core 2 is connected to the oil seal base 4. The oil seal base 4 is provided with an air inlet hole, and the mouthpiece 3 is sleeved on the docking end of the cartridge housing 1.

[0021] Through this technical solution, a filling hole 102 is provided at the upper end of the cartridge housing 1, and a silicone child lock valve 5 is arranged in the filling hole 102. When refilling is needed, the mouthpiece 3 and the cartridge housing 1 are separated, and then the nozzle of the e-liquid bottle is inserted into the filling hole 102 to push open the silicone child lock valve 5 to achieve refilling. After refilling, the nozzle of the e-liquid bottle is pulled out, and the silicone child lock valve 5 automatically seals the filling hole 102 again due to the elastic deformation of the silicone. The setting of the silicone child lock valve 5 makes it so that when the e-cigarette cartridge is accidentally pulled out by a child, the e-liquid will not pour out from the filling hole 102. Moreover, since the filling hole 102 is relatively small, a child's finger cannot be inserted, avoiding the risk of a child accidentally ingesting e-liquid when playing.

[0022] Please refer to Figure 3 , further, the upper end of the mouthpiece 3 is provided with a suction port 301. The suction port 301 extends along the inside of the mouthpiece to form a flared shape that is wider at the top and narrower at the bottom. After the smoke passes through the atomization channel of the atomization core and is output, it enters the user through the flared shape, providing a strong and rich smoke taste. The suction port 301 and the inner wall of the mouthpiece 3 form an inner cavity of the mouthpiece. An airtight silicone member 6 is embedded in the inner cavity of the mouthpiece. The airtight silicone member 6 is provided with a through hole corresponding to the position of the suction port 301. A first sealing ring 601 is provided around the through hole, and a second sealing ring 602 corresponding to covering the periphery of the filling hole 102. The upper surface of the filling hole 102 is sealed by the airtight silicone member 6 to achieve double sealing with the silicone child lock valve, ensuring that the e-liquid will not flow out of the filling hole 102 to the outside of the mouthpiece 3 during use.

[0023] Preferably, the lower end of the mouthpiece 3 is snap-fitted with the side wall of the docking end of the cartridge housing 1. Snap-fitting is a relatively good connection structure method. It can also adopt a tight fit, or in the case of different outer shape designs, a threaded connection method can be used.

[0024] Preferably, the nozzle 3 is made of food-grade plastic material. The sealing silicone part 6 and the nozzle 3 are two separate components, or the sealing silicone part 6 and the nozzle 3 are made into an integrated component by a rubber coating process.

[0025] Please refer to Figure 2 、 Figure 3 for the specific structure of the silicone child lock valve 5. The silicone child lock valve 5 is a hollow cylindrical main body 501. On one side of the hollow cylindrical main body 501, there is a first connecting part 502 protruding outward. On the outside of the first connecting part 502, there is a second connecting part 503 extending upward. Inside the second connecting part 503, a curved notch 5011 is formed between the outer wall of the hollow cylindrical main body 501. On the outer side of the upper end of the second connecting part 503, there is a baffle part 504 extending obliquely upward. The hollow cylindrical main body 501, the first connecting part 502, the second connecting part 503, and the baffle part 504 are integrally formed.

[0026] Please refer to Figure 1 、 Figure 3 for the atomizing core 2. The atomizing core 2 includes an atomizing core outer cover 21, an outer cotton wrap 22, a heating wire 23, an inner cotton wrap 24, and a connecting bracket 25. The upper end of the atomizing core outer cover 21 is a hollow cylindrical insertion part. The side wall of the cover body of the atomizing core outer cover 21 is provided with an oil guiding hole. The connecting bracket 25 includes a circular base and a U-shaped clamping wall. After the inner cotton wrap 24 is sleeved outside the heating wire 23, the whole is sleeved inside the clamping wall. The outer cotton wrap 22 is sleeved outside the clamping wall, and then the whole is inserted into the atomizing core outer cover 21. The bottom of the circular base is sleeved with an insulating silicone 26 with a through hole in the middle. The electrode leads of the heating wire 23 pass through the insulating silicone 26. With the atomizing core 2 designed by this solution, a double cotton wrap structure is adopted, making the oil guiding property of the atomizing core better, which is beneficial to optimizing the oil leakage inside the atomizing core 2 and also beneficial to better guiding oil to the heating wire 23.

[0027] Please refer to Figure 1 、 Figure 3 for the oil seal base 4. The oil seal base 4 includes a bottom cover 41 and an oil cavity sealing silicone 42. The side wall of the oil cavity sealing silicone 42 is provided with a sealing convex ring for sealing the inner wall of the cartridge housing 1. The oil cavity sealing silicone 42 is provided with a through hole for inserting the connecting bracket 25. The bottom cover 41 includes a cover plate part and a bottom cover side wall part. A groove is formed inside the bottom cover side wall part. Inside the groove, there is a first installation position for installing the electrode terminal 7 and a second installation position for embedding a magnet 8. The air inlet hole is arranged at the bottom of the cover plate. The bottom cover side wall part is clamped with the cartridge housing 1.

[0028] Furthermore, the air inlet hole is provided with an air inlet hole wall extending upward inside the bottom of the cover plate, and an adsorption cotton block 43 is arranged in the groove position for avoiding the air inlet hole wall, the first installation position and the second installation position. By arranging the adsorption cotton block 43, it is beneficial that after the electronic cigarette is used, the aerosol steam in the atomization channel forms condensate after cooling and flows down to be adsorbed by the adsorption cotton block 43, which is beneficial to keeping dry, and the user will not inhale the condensate back.

[0029] This solution also discloses an electronic cigarette, which is a cartridge-based electronic cigarette and includes a battery rod main body and a cartridge. The cartridge adopts the electronic cigarette cartridge with a child lock valve provided at the filling port as described above.

[0030] Please refer to Figure 4 , Figure 5 , for the electronic cigarette cartridge with a child lock valve provided at the filling port disclosed in this solution, when refueling is required, the mouthpiece 3 is removed, and the nozzle of the e-liquid bottle is inserted into the filling hole 102. Usually, the nozzle of the e-liquid bottle is designed as a slender tubular nozzle, and the nozzle pushes the baffle part 504 of the silicone child lock valve 5 downward. After the refueling is completed, the nozzle of the e-liquid bottle is pulled out. At this time, due to the initial design of the baffle part 504 which is inclined upward and the elasticity of the silicone material, the baffle part 504 will rebound and reset, and block the inside of the filling hole 102 again, playing the role of a child lock.

[0031] The above has described the embodiments of the present disclosure. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, the practical application or the improvement of the technology in the market, or to enable other ordinary skill in the art in the technical field to understand the embodiments disclosed herein.
