[0002] An electronic cigarette, also known as an electronic nicotine delivery system, is an electronic device that mimics traditional tobacco products. Its main function is to heat the e-liquid to produce an aerosol for users to inhale. Among them, the ceramic atomization core matrix of the electronic cigarette is the core component made of ceramic material in the electronic cigarette.
[0003] The ceramic atomization core matrix of the electronic cigarette generally consists of a ceramic core matrix, a heating element, an e-liquid sleeve cover, a capillary pad sleeve, a connecting piece, a mouthpiece, and an air flow pipe.
[0004] The main working principle of the ceramic atomization core matrix of the electronic cigarette is that when the electronic cigarette works, an electric current passes through the ceramic core matrix to energize and heat the heating element, and then heats the e-liquid. When it reaches a certain temperature, an aerosol is formed. The aerosol enters the air flow pipe through the capillary pad sleeve and is inhaled by people through the mouthpiece.
[0005] Currently, for the existing ceramic atomization core matrix of the electronic cigarette, its e-liquid sleeve cover is generally directly extruded and sleeved on the atomization core matrix. During long-term use or when it is collided during carrying, it is easy to damage the e-liquid sleeve cover, resulting in the leakage of e-liquid, which greatly reduces the sealing and anti-loosening positioning performance of the e-liquid sleeve cover on the ceramic atomization core matrix of the electronic cigarette.

Transverse perforations 211 are opened on the outer sealing ring 21 and the inner sealing ring 22;
[0029] A positioning screw 71 is provided inside the positioning perforation 41. A positioning cap 7 is provided on the positioning screw 71. A limiting disk 72 is provided on the positioning cap 7. A rotating card slot 73 is opened on the positioning cap 7. An erosion-resistant and wear-resistant layer 74 is provided inside the rotating card slot 73. Some of the structures described in this patent are common structures of electronic cigarettes and are prior art. Some prior art structures are not drawn and marked and will not be elaborated.
[0030] The outer sealing ring 21 and the inner sealing ring 22 are both annular structures as a whole and are respectively inserted into the outer sealing groove 5 and the inner sealing groove 6 by extrusion. The outer sealing ring 21 and the inner sealing ring 22 are both made of high-elastic NBR nitrile rubber material, which is wear-resistant, waterproof and durable.
[0031] The vertical height of the outer sealing ring 21 and the inner sealing ring 22 is not lower than the vertical height of the outer ring 20 of the top seat. When the outer sealing ring 21 and the inner sealing ring 22 are inserted into the outer sealing groove 5 and the inner sealing groove 6 by extrusion, at this time, the end face of the outer ring 20 of the top seat is in close contact with the upper end face of the ceramic core matrix 1 to avoid exposure and realize the protection of the side wall of the outer sealing ring 21.
[0032] The positioning perforation 41 penetrates through the outer sealing groove 5 and the inner sealing groove 6. The transverse perforation 211 is aligned with the limit screw groove 81. The positioning screw 71 passes through the positioning perforation 41 and the transverse perforation 211 and is threadedly connected to the limit screw groove 81 to realize the symmetrical threaded locking and positioning between the ceramic core matrix 1 and the e-liquid sleeve cover 2.
[0033] The rotating card slot 73 is an inner groove in the shape of a regular hexagon as a whole. The erosion-resistant and wear-resistant layer 74 is evenly coated along the inner groove wall surface of the rotating card slot 73. The inner groove in the shape of a regular hexagon matches an inner hexagon wrench to rotate the positioning screw 71, improving the rotation stability.
[0034] The opening groove 4 is a rectangular opening groove structure as a whole. The limiting disk 72 is in close contact with the inner groove wall of the opening groove 4. The positioning cap 7 is not higher than the opening groove 4, improving the aesthetics.

[0036] Working mode: A magnetic connector is preset and embedded at the bottom of the ceramic core matrix 1. Then a power supply base is preset at the bottom of the ceramic core matrix 1. The magnetic connector is electrically connected to the power supply base to realize power supply to the heating element embedded in the ceramic core matrix 1, so that the heating element is energized and heated. Then the e-liquid is heated. When it reaches a certain temperature, an aerosol is formed. The aerosol enters the air flow pipe 12 through the capillary gasket sleeve 11 and is then inhaled by people through the mouthpiece 13, which is prior art;
[0037] Before use, the e-liquid sleeve 2 is respectively inserted into the outer sealing groove 5 and the inner sealing groove 6 on the ceramic core base body 1 by being extruded through the outer pressing seal ring 21 and the inner pressing seal ring 22. Then, the positioning screw 71 is horizontally passed through the positioning perforation 41 and the horizontal perforation 211. Next, hold the hex wrench and insert it into the rotation card slot 73 and rotate it clockwise to drive the positioning screw 71 to rotate clockwise and threadedly lock with the limit thread groove 81, thus achieving the double extrusion sealing and positioning effect between the ceramic core base body 1 and the e-liquid sleeve 2. During long-term use or when being carried and collided, it effectively avoids the phenomenon that the e-liquid sleeve 2 shakes, loosens and detaches on the ceramic core base body 1, and further avoids the situation of leaking e-liquid, greatly improving the sealing, anti-loosening and positioning performance of the e-liquid sleeve 2 on the ceramic atomization core base body of the electronic cigarette.
[0038] In addition, by providing a positioning cap 7 with a rotation card slot 73 on the positioning screw 71 and providing a corrosion-resistant and wear-resistant layer 74 inside the positioning cap 7, the rotation corrosion resistance and durability of the positioning cap 7 are further improved.
