Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, in particular to a sealed oil storage component and an electronic atomization device. Background Art

[0002] An electronic atomizer generally includes a cigarette cartridge and a battery assembly electrically connected to the cigarette cartridge. An atomizer is disposed in the cigarette cartridge, and the atomizer heats the cigarette liquid stored in the cigarette cartridge under the electrical drive of the battery assembly, so that the cigarette liquid is heated to generate smoke, and the smoke is inhaled by the user.

[0003] For example, a Chinese utility model patent application (application publication number: CN 115349663 A, application publication date: 2022.11.18) discloses an electronic atomization device, which includes a shell, an atomization component and an oil storage part. The atomization component is provided with an oil storage chamber, and the oil storage part stores smoke oil. The oil storage part and the atomization component are installed in the shell, and the oil storage part is connected to the oil storage chamber. The oil storage part includes a pressure regulating part, which is exposed outside the shell. Through the displacement or deformation of the pressure regulating part, the oil storage part adds smoke oil to the oil storage chamber. By setting an oil storage part containing smoke oil in the electronic atomization device, when the user consumes the smoke oil in the atomization component, the user can squeeze the pressure regulating part by himself, so that the smoke oil in the oil storage part is added to the oil storage chamber, which is convenient for ensuring the flavor content of the smoke oil in the oil storage chamber and improving the user's experience of using the electronic atomization device.

[0004] In this solution, the internal mouthpiece channel is directly connected to the oil storage cavity where the oil storage cotton is located. The smoke oil is mainly locked in the oil storage cavity through the oil storage cotton. During bumpy transportation, some of the smoke oil may directly overflow from the internal mouthpiece channel and pollute the internal mouthpiece channel. In addition, the smoke oil maintains adsorption contact with the oil storage cotton for a long time, causing some of the smoke oil flavor to adhere to the oil storage cotton, which will reduce the taste of the smoke after subsequent atomization.

[0034] The outer circumference of the heating wire 8 is sequentially covered with a cylindrical oil storage cotton 6 and a core tube cover 5, and an oil inlet hole 51 is opened on the side wall of the lower end of the core tube cover 5; in the present embodiment, the cylindrical oil storage cotton 6 can specifically adopt an independent integrated cotton, which has better oil locking and oil control capabilities compared with the method of winding multiple layers of cotton strips on the heating wire in the prior art, and will not cause leakage problems during the suction process. When suction is continued after a period of stagnation, due to its good oil locking ability, there will be no problems with smoke oil and residual oil, and there will be no "gurgling" sound during suction.

[0035] The oil-isolating seal 3 comprises a bottom sleeve 33 which is slidably mounted on the outer periphery of the core barrel cover 5, the upper end of the bottom sleeve 33 is integrally connected with a barrel end plate 34, the upper end of the barrel end plate 34 is also integrally connected with a top sleeve 32 which is used for slidingly mounting on the lower end of the internal cigarette holder passage 202, the upper end surface of the barrel end plate 34 is also connected with a pull rod portion 31, the top end of the pull rod portion 31 extends out of the internal cigarette holder passage 202;

[0036] When the bottom sleeve 33 is located at the bottom end, the bottom sleeve 33 blocks the oil inlet hole 51; when the pull rod portion 31 is separated from the cylinder end plate 34 due to the pulling force, the oil-isolating seal 3 forms a hollow conducting channel, and the bottom sleeve 33 releases the blockage of the oil inlet hole 51 due to the upward movement.

[0037] As a specific solution, in order to facilitate breaking of the tie rod 31 so that the oil-isolating seal 3 forms a hollow conducting channel, a breaking ring groove 341 is also distributed on the periphery of the connection between the cylinder end plate 34 and the tie rod 31. In this embodiment, the oil-isolating seal 3 can be specifically a silicone seal.

[0038] The working principle of the utility model is as follows: before use, the bottom sleeve 33 of the oil-isolating seal 3 is located at the bottom, and the bottom sleeve 33 can completely block the oil inlet hole 51, preventing the smoke oil in the oil storage cavity 100 from entering the core tube cover 5, and has a good sealing effect, which can prevent the smoke oil from directly immersing into the cylindrical oil storage cotton 6;

The tobacco oil then soaks into the cylindrical oil storage cotton 6 and contacts the heating wire 8. Then, the user pulls the pull rod part 31 hard to break the breaking ring groove 341, and the pull rod part 31 is separated from the barrel end plate 34, so that the oil-isolating seal 3 forms a hollow conductive channel, and the smoke atomized by the heating wire 8 can subsequently pass through the oil-isolating seal 3 and the internal mouthpiece channel 202, and finally be discharged from the mouthpiece part 201.

[0041] In the embodiment of the utility model, the oil-isolating seal 3, on the one hand, serves as a sealing component, which can completely isolate the tobacco oil in the oil storage chamber 100 from the internal mouthpiece channel 202, thereby achieving effective sealing and preventing the tobacco oil from overflowing and contaminating the mouthpiece 201; on the other hand, the oil-isolating seal 3 serves as a hollow conducting channel and a smoke outlet channel during subsequent use, so that the atomized smoke can be discharged.
