Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an oil-proof atomizer and an oil-proof structure for electronic cigarettes. Background Technology

[0002] Leak-proof atomizers are devices used in e-cigarettes to atomize e-liquid / vapor. Because their oil storage chamber is connected to the airflow channel, vibration, pressure, and temperature changes during inhalation can easily cause excessive e-liquid to flow along the airflow channel to the mouthpiece or electrode, leading to leakage.

[0003] Currently, the anti-leakage structures for e-cigarettes vary. Some use a radial heater and a multi-hole plug to supply oil, which reduces the risk of leakage, but the oil supply speed is slow and the heater is prone to dry burning, posing certain safety hazards. Others use a design that combines a dripping device and a heating device working simultaneously to solve the problem of e-cigarette leakage, but this makes it difficult to control the oil supply and the atomizer structure is relatively complex. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides an oil-proof atomizer and an oil-proof structure for electronic cigarettes. The overall structure is simple, easy to manufacture and assemble. The amount of e-liquid entering the atomizer tube can be controlled by changing the number of oil guide slots on the atomizer tube. It is convenient, practical, and easy to operate, and has high atomization efficiency. It does not cause the heating wire to burn dry, and can avoid or reduce the generation of liquid e-liquid residue in the atomizer tube. In conjunction with the sealing structure between the atomizer tube, the outer cover, and the outer shell, it can prevent e-liquid leakage on the inner and outer sides of the atomizer tube.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The leak-proof oil atomizer comprises, from the outside in, an outer cover and an atomizing tube. A heating element is installed inside the atomizing tube. An inner oil storage chamber is formed on the inner wall of the outer cover around the atomizing tube. Both ends of the atomizing tube extend to the outside of the outer cover. It also includes oil-collecting cotton and oil-guiding cotton, wherein:

[0007] The outer cover has a ring structure, and one or more oil inlet slots are formed on its side wall that communicate with the inner oil storage cavity. The inner walls of both ends of the outer cover are sealed to the outer wall of the atomizing tube.

[0008] The oil-storing cotton has a ring structure and is fitted inside the inner oil-storing cavity, with its inner and outer walls respectively abutting against the atomizing tube and the outer cover.

[0009] The oil-guiding cotton has a ring structure and is installed inside the atomizing tube. Its inner and outer walls are respectively attached to the heating element and the atomizing tube. The atomizing tube has several radially extending oil-guiding grooves between the oil-storage cotton and the oil-guiding cotton.

[0010] As a further explanation of the above technical solution:

[0011] In the above technical solution, the heating element includes a pin and a heating wire. One end of the pin extends to the outside of the atomizing tube, and the heating wire is arranged around the other end. The heating wire has a mesh structure, and its outer end is attached to the inner wall of the oil-guiding cotton.

[0012] In the above technical solution, a sealing ring is embedded on the inner wall of the lower end of the outer cover, and its two ends abut against the outer cover and the oil storage cotton, respectively.

[0013] In the above technical solution, the inner wall and outer wall of the sealing ring are both formed with concave and circumferentially extending clearance grooves.

[0014] One technical solution adopted by this utility model is as follows:

[0015] The electronic cigarette has an anti-leakage structure, wherein the electronic cigarette is provided with the anti-leakage atomizer described in the above technical solution, and the anti-leakage atomizer is surrounded by a shell, both ends of which are sealed to the atomizing tube. An outer oil storage cavity for storing e-liquid is formed between the inner wall of the shell and the outer cover.

[0016] Compared with the prior art, the advantages of this utility model are as follows: the overall structure is simple, easy to produce and assemble. By setting oil-guiding cotton and oil-reserving cotton inside and outside the atomizing tube, and setting several oil-guiding grooves on the atomizing tube, and setting a heating wire inside the oil-guiding cotton, the e-liquid can be smoothly guided into the atomizer. The amount of e-liquid entering the atomizing tube can be controlled by changing the number of oil-guiding grooves on the atomizing tube. It is convenient, practical and easy to operate. Moreover, the ring-shaped and mesh-like heating wire has a large contact area with the oil-guiding cotton, which can quickly heat and atomize the e-liquid. The atomization efficiency is high and there is no dry burning of the heating wire. It can avoid or reduce the generation of liquid e-liquid residue in the atomizing tube. In conjunction with the sealing structure between the atomizing tube, the outer cover and the outer shell, it can prevent e-liquid leakage on the inside and outside of the atomizing tube.

[0024] like Figure 1-2 As shown, the leak-proof atomizer 10 includes, from the outside to the inside, an outer cover 1 and an atomizing tube 2. A heating element 3 is installed inside the atomizing tube 2. An inner oil storage chamber is formed on the inner wall of the outer cover 1 around the atomizing tube 2. Both ends of the atomizing tube 2 extend to the outside of the outer cover 1. It also includes oil-collecting cotton 4 and oil-guiding cotton 5, wherein:

[0025] The outer cover 1 has a ring structure, and one or more oil inlet slots 101 connected to the inner oil storage cavity are formed on its side wall. The inner walls of both ends of the outer cover 1 are sealed to the outer wall of the atomizing tube 2.

[0026] The oil storage cotton 4 has a ring structure and is installed in the inner oil storage cavity, with its inner wall and outer wall respectively attached to the atomizing tube 2 and the outer cover 1.

[0027] The oil-guiding cotton 5 has a ring structure and is installed inside the atomizing tube 2. Its inner and outer walls are respectively attached to the heating element 3 and the atomizing tube 2. Several radially extending oil-guiding grooves 201 are provided on the atomizing tube 2 between the oil-storage cotton 4 and the oil-guiding cotton 5.

[0028] In application, the amount of e-liquid entering the atomizing tube 2 can be controlled by changing the number of oil guide grooves 201 on the atomizing tube 2, which is convenient, practical and easy to operate.

[0029] like Figure 3 As shown, the heating element 3 includes a pin 301 and a heating wire 302. One end of the pin 301 extends to the outside of the atomizing tube 2, and the other end is surrounded by the heating wire 302. The heating wire 302 has a mesh structure, and its outer end is attached to the inner wall of the oil-guiding cotton 5.

[0030] In this embodiment, the annular and mesh-like heating wire 302 has a larger contact area with the oil-guiding cotton 5, which can quickly heat and atomize the e-liquid adsorbed on it, resulting in high atomization efficiency and avoiding or reducing liquid e-liquid residue.

[0031] like Figure 2-3 As shown, a sealing ring 6 is embedded on the inner wall of the lower end of the outer cover 1, with its two ends abutting against the outer cover 1 and the oil-collecting cotton 4, respectively. In this embodiment, a recessed and circumferentially extending clearance groove 601 is formed in the middle of both the inner and outer walls of the sealing ring 6.

[0032] It is understandable that at least three end faces of the inner sealing ring 6 of the leak-proof atomizer 10 are attached to other structural components, namely, the inner wall is attached to the atomizing tube 2, the inner end is attached to the oil storage cotton 4, and the outer wall is attached to the inner wall of the outer cover 1. The anti-vacuum grooves 601 on its inner and outer walls can prevent the formation of a vacuum between it and other structural components, so as to facilitate disassembly and use.

[0033] When using, such as Figure 3As shown, the inhalation action generates negative pressure inside the atomizing tube 2, causing the e-liquid soaked in the oil storage cotton 4 to enter the oil guiding cotton 5 through the oil guiding groove 201, and further be absorbed onto the inner wall of the oil guiding cotton 5. After being heated by the heating wire 302, it is atomized and drawn out with the gas. The sealing structure at both ends of the outer cover 1 can prevent the e-liquid in the inner oil storage chamber from leaking from the outer periphery of the atomizing tube 2 to the outer side of the outer cover 1.

[0034] like Figure 4 As shown, in a specific application embodiment of the above embodiments, an anti-leakage structure for electronic cigarettes is disclosed. The electronic cigarette is provided with the anti-leakage atomizer 10 of the above embodiments. The anti-leakage atomizer 10 is surrounded by a shell 20. Both ends of the shell 20 are sealed and connected to the atomizing tube 2. An outer oil storage cavity 7 for storing e-liquid is formed between the inner wall of the shell 20 and the outer cover 1.

[0035] During use, the e-liquid in the outer oil storage chamber 7 enters the inner oil storage chamber through the oil inlet groove 101 on the outer cover 1 and is absorbed by the oil storage cotton 4. The sealing structure between the outer shell 20 and the atomizing tube 2 can further prevent e-liquid leakage, making it more convenient and reliable to use.

[0036] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the technical scope of this utility model.
