In addition, the words "first", "second" and the like are only used to distinguish multiple components or structures with the same or similar structures, and do not represent any special limitation on the setting order or connection relationship.

[0029] This embodiment relates to an electronic cigarette atomizer, referring to Figures 1 to 5 , including an atomizer body 1 and an atomizer assembly 2 arranged in the atomizer body 1, wherein the atomizer body 1 includes an oil storage tank body 11 and a base assembly 12, the oil storage tank body 11 has an oil storage cavity 111 for storing tobacco oil, and the base assembly 12 is used to cooperate with the oil storage tank body 11 to achieve the closure of the oil storage cavity 111.

[0030] Specifically, the base assembly 12 includes a threaded base 121, a first sleeve 122, and a second sleeve 123, wherein the side of the threaded base 121 facing away from the oil storage tank body 11 is provided with an external threaded column 1211 for threading with the battery rod, the atomizer assembly 2 is provided on the side of the threaded base 121 facing the oil storage cavity 111, and the atomizer assembly 2 extends into the oil storage cavity 111. The first sleeve 122 is fixedly provided on the outside of the threaded base 121, and the oil storage tank body 11 is provided with an insertion portion 112 that is plugged and matched with the first sleeve 122, the diameter of the insertion portion 112 is smaller than the first sleeve 122, and the insertion portion 112 extends into the first sleeve 122. The diameter of the second sleeve 123 is smaller than that of the first sleeve 122, and the diameter of the second sleeve 123 is larger than the diameter of the insertion portion 112. The second sleeve 123 is arranged between the first sleeve 122 and the insertion portion 112, and the two sides of the second sleeve 123 are respectively fixedly connected to the first sleeve 122 and the insertion portion 112 of the oil storage tank body 11.

[0031] In addition, it should be noted that, in the present embodiment, the first sleeve 122 and the second sleeve 123 are tightened by threaded cooperation, that is, the first sleeve 122 is provided with an internal thread, and the second sleeve 123 is provided with an external thread, and the connection between the first sleeve 122 and the second sleeve 123 is achieved by the cooperation between the internal thread and the external thread, and the inner side of the second sleeve 123 is fixed to the insertion portion 112 of the oil storage tank body 11 by gluing.

[0032] The atomizer body 1 further comprises a snap assembly 13 , which is disposed between the threaded base 121 and the second sleeve 123 , and is used to lock the second sleeve 123 and the threaded base 121 , thereby ensuring the stability of the connection between the base assembly 12 and the oil storage tank body 11 .

[0033] It can be understood that the second sleeve 123 is locked with the threaded base 121 by the buckle assembly 13, so that the connection between the base assembly 12 and the oil storage tank body 11 is relatively firm. When the atomizer body 1 needs to be removed from the battery rod, that is, when the oil storage tank body 11 or the base assembly 12 is screwed in reverse, the oil storage tank body 11 and the base assembly 12 will not rotate relative to each other, so that the oil storage tank body 11 and the base assembly 12 will not loosen or separate, and the atomizer body 1 can be completely removed from the battery rod without oil leakage.

[0034] Furthermore, the buckle assembly 13 includes a groove 131 opened on the outside of the threaded base 121, a buckle 132 arranged in the groove 131, and a protrusion 133 arranged on the second sleeve 123. The groove 131 is arranged along the circumferential direction of the threaded base 121, the protrusion 133 protrudes outward from the second sleeve 123, and the buckle 132 cooperates with the protrusion 133.

[0035] Furthermore, the buckle 132 is elastically disposed in the groove 131, and the buckle 132 includes an integrally formed vertical portion 1321 and an outer protrusion 1322, the vertical portion 1321 is located in the groove 131, the outer protrusion 1322 is located at the upper part of the side of the vertical portion 1321 away from the groove 131, and the bottom side of the outer protrusion 1322 abuts against the top surface of the convex edge 133.

[0036] During assembly, first install the buckle 132 on the threaded base 121, and press the threaded base 121 into the first sleeve 122. At this time, the second sleeve 123 and the insertion portion 112 of the oil storage tank body 11 are glued and fixed to achieve the connection and fixation between the second sleeve 123 and the insertion portion 112. Finally, the first sleeve 122 is rotated and installed into the second sleeve 123. The second sleeve 123 is clamped by the buckle 132 on the threaded base 121 and the convex edge on the second sleeve 123. This makes the connection between the base assembly 12 and the oil storage tank body 11 more stable, improves the overall stability of the atomizer body 1, and prevents the base assembly 12 and the oil storage tank body 11 from loosening or separation when the atomizer body 1 is rotated in the reverse direction.

[0037] Furthermore, in this embodiment, the oil storage tank body 11 is made of glass, and the threaded base 121, the first sleeve 122, the second sleeve 123 and the buckle assembly 13 are all made of metal.

[0038] By making the oil storage tank 11 of glass material, people can directly observe the oil inside the oil storage tank 11, so that people can add oil or replace the entire atomizer conveniently. The threaded base 121, the first sleeve 122, the second sleeve 123 and the buckle assembly 13 made of metal material have the advantages of corrosion resistance and wear resistance, and are easy to obtain and have low production cost.

[0039] Furthermore, the atomizing assembly 2 includes a silicone rubber 21 arranged on a threaded base 121, a central tube 22 sleeved outside the silicone rubber 21, a heating element 23 arranged inside the central tube 22, an oil-absorbing cotton 24 sleeved outside the heating element 23, and an electrode 25 arranged below the heating element 23, wherein the threaded base 121, the silicone rubber 21, the central tube 22, the heating element 23 and the oil-absorbing cotton 24 are all coaxially arranged, the silicone rubber 21 is used to seal the oil, and the side wall of the central tube 22 is provided with a plurality of oil inlets 221 connected to the oil storage chamber 111, and the plurality of oil inlets 221 are connected to the oil storage chamber 111. The oil inlets 221 are evenly distributed along the circumferential direction of the central tube 22, so that the tobacco oil in the oil storage chamber 111 can enter the central tube 22 through the oil inlet 221 and be absorbed by the oil-absorbing cotton 24. The heating element 23 is arranged in a columnar shape, and the outer wall of the heating element 23 abuts against the inner wall of the oil-absorbing cotton 24. The electrode 25 is located in the external threaded column 1211 of the threaded base 121. Two conductive pins are connected to the bottom side of the heating element 23. The two conductive pins extend vertically downward at one end away from the heating element 23 and are respectively connected to the two sides of the electrode 25.

[0040] It can be understood that by providing electrical energy to the electrode 25, the heating element 23 is heated and the tobacco oil adsorbed on the oil-absorbing cotton 24 is atomized, thereby achieving the atomization of the tobacco oil, making it convenient for people to inhale.

[0041] Furthermore, the heating element 23 is a ceramic heating wire, and the oil-absorbing cotton 24 is made of non-woven fabric.

[0042] It is understandable that, when using ceramic heating wire as the heating element 23, firstly, the ceramic heating wire has good insulation performance, high temperature resistance and chemical stability, secondly, the thermal conductivity of ceramics, the ceramic heating wire can provide uniform heating, reduce the generation of hot spots and cold spots, and has high thermal efficiency, and can quickly reach the required working temperature, thirdly, ceramics as a non-metallic material reduces the risk of short circuit and electrical failure, in addition, the ceramic heating wire has a longer service life than the metal heating wire. Non-woven fabric is used as the oil-absorbing cotton 24, because non-woven fabric has the advantages of durability, environmental protection, and low price.

[0043] Furthermore, a sealing silicone 113 is provided in the oil storage tank body 11, and the atomizing assembly 2 is all dissolved in the sealing silicone 113. The bottom side of the sealing silicone 113 extends into the threaded base 121 and is tightly abutted against the silicone 21, and the side wall of the sealing silicone 113 is provided with a through hole corresponding to the oil inlet 221 on the center tube 22.

[0044] By providing the sealing silica gel 113 , the gap between the oil storage tank body 11 and the base assembly 12 can be further sealed, thereby improving the sealing performance of the entire atomizer body 1 .

[0045] Furthermore, a suction nozzle 114 is provided at one end of the oil storage tank body 11 away from the threaded base 121, and an air suction channel 115 connected with the suction nozzle 114 is provided in the oil storage tank body 11, and one end of the air suction channel 115 away from the suction nozzle 114 extends into the sealing silicone 113 and is connected with the center tube 22, and a frustum is provided in the sealing silicone 113 for abutting against the air suction channel 115.

[0046] Through the above arrangement, the smoke oil atomized by the heating body can enter the air inhalation channel 115 and then the suction nozzle 114, so that people can inhale it conveniently.

[0047] In addition, this embodiment also provides an electronic cigarette, including the electronic cigarette atomizer and a power supply device as described above, the power supply device includes a battery rod, the battery rod is threadedly connected to the atomizer body 1, and the battery rod is used to supply power to the atomization assembly 2 in the atomizer body 1.

[0048] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
