Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomization device for refilling e-liquid with a flip-top. Background Technology

[0002] Electronic cigarettes generally consist of a casing, inside which are installed a bracket, a battery, and a circuit board. The upper surface of the bracket is equipped with a spring pin, and the upper surface of the bracket and the upper part of the casing form a docking space for holding the cartridge. The lower part of the spring pin is connected to the circuit board via a wire, and the circuit board is connected to the battery. Air inlets are provided on the side or bottom wall of the casing to facilitate the inflow of outside air.

[0003] The cartridge is generally sealed. The upper part of the cartridge has a mouthpiece, and the side wall of the cartridge has an oil filling hole fitted with a sealing plug. The lower part of the cartridge has a base with an air inlet. The air inlet and the mouthpiece are connected by a tube. The tube contains an atomizer core and has an oil inlet. The inner wall of the cartridge, the upper surface of the base, and the outer wall of the tube form an oil reservoir containing e-liquid. The atomizer core is connected to the oil reservoir through the oil inlet. The base also has an electrode post. The atomizer core is connected to the upper part of the electrode post via a lead wire. The lower part of the electrode post protrudes from the lower surface of the base. In use, the cartridge is assembled in the mating space. The electrode post presses against the spring pin. The battery, through the circuit board, spring pin, electrode post, and atomizer core, forms a circuit. The battery outputs electrical energy to the heating wire of the atomizer core. When energized, the heating wire generates heat, heating the e-liquid absorbed by the wicking cotton of the atomizer core into vapor, thus atomizing the e-liquid.

[0004] As e-cigarettes are used continuously, the e-liquid is constantly consumed. When the e-liquid is depleted, the sealing plug needs to be removed from the refill hole and set aside. E-liquid is then added back into the cartridge through the refill hole. After refilling, the sealing plug is reinserted into the refill hole to seal the cartridge. This method of removing and reinstalling the sealing plug, while simple, can easily lead to the sealing plug being lost or e-liquid leaking out. Furthermore, when e-cigarettes are not in use, they need to be placed in a pocket or on a table, exposing the mouthpiece to the outside world, which makes it easy for the mouthpiece to accumulate dust.

[0005] Therefore, it is necessary to develop an electronic cigarette to overcome the aforementioned shortcomings. Utility Model Content

[0006] The main purpose of this application is to provide a flip-top atomizing device for refilling e-liquid, which solves the problems of mouthpieces getting dusty and refilling being inconvenient.

[0007] To achieve the above objectives, this application proposes a flip-top e-liquid refilling atomizing device, comprising:

[0008] An atomizer includes an e-liquid reservoir and a mouthpiece, wherein the e-liquid reservoir is filled with e-liquid;

[0009] A cover body, comprising an oil supply chamber containing e-liquid;

[0010] A hose, one end of which is connected to the oil storage tank and the other end of which is connected to the oil supply tank;

[0011] When the cover is fastened to the atomizer, the cover covers the mouthpiece, and the oil supply chamber supplies oil to the oil storage chamber through a hose. When the cover is separated from the atomizer, the oil supply chamber stops supplying oil to the oil storage chamber.

[0012] The atomizer includes a body, an oil reservoir is provided inside the body, the mouthpiece is located above the oil reservoir and protrudes from the upper surface of the body, and the cover is located above the body.

[0013] The cover includes an outer shell with an opening at the bottom. The opening is provided with a sealing element. The sealing element and the inner wall of the outer shell form the oil supply chamber. A groove is formed at the bottom of the sealing element, and the suction nozzle is installed in the groove. Multiple flow channels are formed on the top wall of the groove.

[0014] The upper surface of the seal has an oil supply channel extending downwards and penetrating the side of the seal outwards. The other end of the hose is connected to the outlet of the oil supply channel.

[0015] The upper surface of the seal is recessed with multiple drainage grooves, one end of which is connected to the inlet of the oil supply channel.

[0016] The lower surface of the seal is provided with a support portion, which is located between the oil supply channel and the groove, and is used to abut against the upper part of the body.

[0017] The main body has an inwardly extending transfer channel on its side, which extends inward and penetrates the side wall of the oil storage tank. One end of the hose is connected to the inlet of the transfer channel, and the outlet of the transfer channel is connected to the oil storage tank.

[0018] The oil storage tank is equipped with oil storage cotton, and an atomizing tube is installed in the center of the oil storage cotton. The atomizing tube is equipped with an atomizing core, and an oil inlet is opened at the atomizing core. An air inlet is provided at the bottom of the oil storage tank, and the lower part of the atomizing tube is connected to the air inlet.

[0020] The hose is made of soft rubber material, has a circular cross-section, and has multiple raised textures on its outer surface.

[0021] When the cover is attached to the atomizer, it covers the mouthpiece, preventing the e-cigarette from being inhaled normally. This effectively prevents dust from the air from contaminating the mouthpiece. The e-liquid supply chamber supplies e-liquid to the e-liquid storage chamber via a hose, and can also refill the storage chamber to replenish it, facilitating smooth atomization for the next cycle. When the cover is separated from the atomizer, the e-cigarette can be used normally, and the e-liquid supply chamber stops supplying e-liquid to the storage chamber, effectively preventing overfilling and ensuring efficient use of e-liquid.

[0036] the following Figure 1-6A flip-top e-liquid refilling atomizing device includes: an atomizer 1, comprising an e-liquid reservoir 12 and a mouthpiece 14, wherein the e-liquid reservoir 12 is filled with e-liquid, and the mouthpiece 14 is located above the e-liquid reservoir 12. The e-liquid is heated in the atomizer 1 to produce vapor, which flows out through the mouthpiece and is positioned to contact the mouth of the user for easy entry of vapor into the mouth. The atomizer of this design can operate independently, heating to produce vapor; and a cover 2, comprising an e-liquid supply reservoir 23, which is filled with e-liquid. The cover 2 and the atomizer... The two parts 1 and 2 can be connected by a rotating shaft, which facilitates the opening and closing of the cap 2 on the atomizer 1 and also makes it easy for the user to operate the cap 2. A flexible tube 3, one end of which is connected to the oil reservoir 12 and the other end to the oil supply reservoir 23, is made of soft rubber material. The cross-section of the flexible tube 3 is circular, and the outer surface of the flexible tube 3 has multiple raised lines. The raised lines increase the bonding strength of the flexible tube 3 and prevent it from breaking during bending. The flexible tube 3 can also be made of silicone material, in which case care must be taken to ensure the silicone is flexible and not too stiff. Made of transparent material, allowing users to easily observe the flow of e-liquid. The hose 3 can also be made of opaque material. When the cover 2 is fastened to the atomizer 1, it covers the mouthpiece 14, preventing normal inhalation and effectively preventing dust from the air from contaminating the mouthpiece 14. The e-liquid supply chamber 23 supplies e-liquid to the e-liquid storage chamber 12 through the hose 3, and can also refill the e-liquid storage chamber 12 to replenish it for smooth atomization. When the cover 2 is separated from the atomizer 1, the supply... When the e-liquid tank 23 stops supplying e-liquid to the e-liquid storage tank 12, it can effectively prevent excessive filling of e-liquid and ensure efficient utilization of e-liquid. For example, when the cap 2 and the atomizer 1 are at the same height, the e-liquid tank 23 and the e-liquid storage tank 12 are at the same height. The e-liquid tank 23 no longer supplies e-liquid to the e-liquid storage tank 12 through the hose 3. It can be understood that at this time, it is no longer necessary for the e-liquid tank 23 to supply e-liquid to the e-liquid storage tank 12, because when the cap 2 is closed, the e-liquid in the e-liquid tank 23 keeps flowing into the e-liquid storage tank 12. The e-liquid storage tank 12 has obtained enough e-liquid and needs to stop supplying e-liquid.

[0037] The atomizer 1 includes a body 11, which is made of plastic and has an elliptical cross-section. The body 11 can also be made of metal and has a circular, square, or polygonal cross-section. An e-liquid reservoir 12 is provided inside the body 11. The reservoir 12 contains e-liquid and is used to hold and receive e-liquid from the supply tank 23. The reservoir 12 itself also contains e-liquid. The mouthpiece 14 is positioned... At the upper part of the oil storage tank 12, the suction nozzle 14 protrudes from the upper surface of the body 11, making it easy for a person's mouth to hold the suction nozzle 14. The cover 2 is located at the upper part of the body 11. When the cover 2 is opened from the upper part of the body 11, the suction nozzle 14 is exposed to the air. When the suction nozzle 14 is fastened to the upper part of the body 11, the suction nozzle 14 is isolated from the outside air. The edge of the cover 2 abuts against the edge of the body 11, making it easy for the cover 2 to seal the suction nozzle 14 in the body 11.

[0038] The cover 2 is made of plastic material and includes an outer shell 21 with a lower opening 211. The cross-section of the outer shell 21 is elliptical, matching the shape of the body 11. A sealing element 22 made of silicone material is provided in the opening 211, which seals the upper part of the outer shell 21. The sealing element 22 and the inner wall of the outer shell 21 form the e-liquid supply chamber 23, which contains a large amount of e-liquid, for example, 5 ml. 10ml, 15ml, 20ml, etc., the lower part of the sealing member 22 has an upward groove 224, the suction nozzle 14 is installed in the groove 224, the shape of the groove 224 matches the upper part of the suction nozzle 14, so that the suction nozzle 14 can be received in the groove 224. The top wall of the groove 224 has multiple flow channels 222, the flow channels 222 are strip-shaped, when the remaining smoke in the suction nozzle 14 flows upward, it encounters the flow channel 222 and can be turned into condensate and stored in the flow channel 222.

[0039] The upper surface of the seal 22 has a downward-facing oil supply channel 223. The oil supply channel 223 extends downward and outward through the side of the seal 22. The other end of the hose 3 is connected to the outlet of the oil supply channel 223. The oil supply channel 223 is formed by opening downward and then outward from the upper surface of the seal 22. The upper end of the hose 3 is connected to the bottom of the oil supply channel 223. One end of the hose 3 is the lower end of the hose 3, and the other end of the hose 3 is the upper end of the hose 3. When the cover 2 is closed, it facilitates the entry of e-liquid from the oil supply chamber 23 into the hose 3. When the cover 2 is open, it prevents the e-liquid in the oil supply chamber 23 from flowing to the oil storage chamber 12 through the hose 3.

[0040] The upper surface of the seal 22 is recessed with a plurality of drainage grooves 221. One end of the drainage grooves 221 is connected to the inlet of the oil supply channel 223. The design of the drainage grooves 221 can reduce the adhesion between large molecules of e-liquid, turn large molecules of e-liquid into small molecules, reduce the stickiness between e-liquid molecules, facilitate the flow of e-liquid in the oil supply chamber 23, and facilitate the entry of e-liquid into the oil supply channel 223.

[0041] The lower surface of the sealing element 22 is provided with a support portion 225. The support portion 225 is located between the oil supply channel 223 and the groove 224. When the cover 2 is rotatable relative to the body 11, when the cover 2 is rotated and closed, the support portion 225 is used to abut against the upper part of the body 11 and plays a buffering role for the cover 2.

[0042] A connecting channel 15 is provided on the side of the main body 11, extending inward and penetrating the side wall of the oil storage tank 12. One end of the flexible hose 3 is connected to the inlet of the connecting channel 15, and the outlet of the connecting channel 15 is connected to the oil storage tank 12, facilitating the entry of e-liquid into the oil storage tank 12. The outlet of the connecting channel 15 is located at the upper part of the oil storage tank 12, facilitating the entry of e-liquid and preventing it from flowing back into the oil supply tank 23. When the cover 2 is fastened to the main body 11, the flexible hose 3 is bent into a U-shape. When the cover 2 is separated from the main body 11, the opening 211 of the cover 2 faces upward, and the flexible hose 3 is horizontal, preventing e-liquid in the oil supply tank 23 from entering the oil storage tank 12 through the flexible hose 3.

[0043] The oil storage chamber 12 is equipped with an oil-absorbing cotton 13, which can absorb and store e-liquid. The cross-section of the oil storage chamber 12 can be circular or square, and the cross-section of the oil-absorbing cotton 13 can also be circular or square. The shape of the oil-absorbing cotton 13 matches the shape of the oil storage chamber 12. An atomizing tube 16 is installed in the center of the oil-absorbing cotton 13. The center of the oil-absorbing cotton 13 is hollow. The cross-section of the atomizing tube 16 is circular. An atomizing core 17 is installed in the atomizing tube 16. An oil inlet is opened in the atomizing tube 16 corresponding to the atomizing core 17. An air inlet is provided at the bottom of the oil storage chamber 12. The lower part of the atomizing tube 16 is connected to the air inlet. The mouthpiece 14 has a suction channel 141. The upper part of the atomizing tube 16 is connected to the lower part of the suction channel 141. The atomizing core 17 includes a heating element and an oil-guiding cotton. The oil-guiding cotton covers the outside of the heating element, which is bent into a cylindrical shape. Both ends of the heating element are connected to a circuit board, and the oil-guiding cotton corresponds to the oil inlet.

[0044] The main body 11 is also equipped with a battery and a circuit board. The battery and circuit board are isolated from the oil storage tank 12. The battery is connected to the circuit board through a wire. The circuit board is connected to the heating element of the atomizing core 17 through a wire. The circuit board adjusts the heating power of the heating element.

[0045] The circuit design is as follows: the battery is connected to the circuit board via wires, and the circuit board is connected to the heating element via wires. The battery outputs current to the heating element, and the heating element generates heat after being powered on.

[0046] The oil circuit design is as follows: the e-liquid in the oil storage tank 12 flows through the oil inlet to the guide cotton and is heated into smoke on the heating element; when the cover 2 is fastened to the main body 11, the e-liquid in the oil supply tank 23 flows to the oil storage tank 12 through the hose 3 to replenish the oil storage tank 12. When not vaping, the oil storage tank 12 is filled with oil, and the mouthpiece can also be isolated from the outside. When vaping is needed, the cover 2 is opened from the top of the main body 11, and the cover 2 is in a horizontal position with the hose 3 facing upward. The e-liquid in the oil supply tank 23 no longer flows into the oil storage tank 12, which can avoid supplying oil to the oil storage tank 12 for a long time and prevent the oil storage tank 12 from leaking.

[0047] The air path of this design is as follows: outside air enters the atomizing tube 16 through the air inlet and flows upward along the atomizing tube 16. The air flows through the heating element and mixes with the smoke generated by the heating element. After the smoke and air are mixed, they flow upward and flow out from the upper part of the atomizing tube 16, enter the suction channel 141, and flow into the oral cavity from the mouthpiece.

[0048] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
