In addition, the descriptions of up, down, left, right, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the drawings.

[0029] In addition, unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art. The terms used in this specification are only for describing specific embodiments, not for limiting the present invention. The term "and / or" used herein includes any combination of one or more related listed items.

The central tube 7 is provided with an oil hole 72 along the radial direction of the central tube 7 at the heating element 9, and the oil hole 72 connects the atomization channel 71 with the outer surface of the central tube 7.

[0031] The rotating seal 12 is cylindrical as a whole, and a first through hole 1202 is opened along the axial direction of the rotating seal 12. The center tube 7 is inserted into the first through hole 1202, and the position of the oil hole 72 corresponds to the position of the rotating seal 12. The rotating seal 12 can rotate relative to the center tube 7. Here, the rotating seal 12 and the center tube 7 can be gap-fitted to achieve this. In the present embodiment, the rotating seal 12 rotates to silicone, and the rotating seal 12 and the center tube 7 have an interference fit. By utilizing the elasticity of silicone, the rotating seal 12 can still rotate relative to the center tube 7, and the center tube 7 can fit tightly with the first through hole 1202. The rotary seal 12 is provided with an oil passage 1201. In the present embodiment, the oil passage 1201 is a fan-shaped groove arranged opposite to each other, and the fan-shaped groove is connected with the first through hole 1202. That is, when the rotary seal 12 is installed on the center tube 7, the fan-shaped groove can be connected with the oil hole 72 by rotating the rotary seal 12, or the fan-shaped groove corresponds to the outer surface position of the center tube 7 where the oil hole 72 is not provided.

[0032] Sector-shaped protrusions 1203 are also provided on both sides of the sector-shaped groove. When the sector-shaped groove does not correspond to the position of the oil hole 72, the sector-shaped protrusion 1203 corresponds to the position of the oil hole 72 and blocks the oil hole 72 with the sector-shaped protrusion 1203. Thus, the rotating seal 12 can play the role of opening and closing the oil hole 72 of the center tube 7.

[0033] Reference Figure 4 , Figure 7 and Figure 8 In addition, an oil tank 17 is provided above the rotary seal 12, and the fan-shaped groove is connected to the oil tank 17.

The smoking nozzle 1 is fixed to the central tube 7 through a connecting piece 6. The bracket 11, the cylindrical ring 3, the smoking nozzle 1 and the central tube 7 are combined to form an oil tank 17.

[0034] Specifically, a first annular groove is formed on the outer cylindrical surface at the uppermost end of the bracket 11, a second annular groove is formed on the horizontal step surface at the shoulder 1103 of the bracket 11, the third sealing ring 10 is sleeved in the first annular groove, the second annular groove is filled with glass glue, the cylindrical ring 3 is sealed with the bracket 11 through the third sealing ring 10 and the glass glue, wherein the cylindrical ring 3 is a transparent glass ring or a plastic ring; the sealing ring 2 is sleeved in the annular groove at the lower end of the smoking nozzle 1, the sealing ring 2 abuts against the inner wall of the annular groove, and when the sleeve is When the sealing ring 2 is inserted into the upper end of the cylindrical ring 3, the sealing ring 2 is squeezed by the inner wall of the annular groove and the inner wall of the cylindrical ring 3 respectively, thereby achieving a sealed fit between the smoking nozzle 1 and the cylindrical ring 3; the outer circumferential surface of the lower end of the connecting piece 6 is interference fit with the inner wall of the atomization channel 71 of the central tube 7, and an external thread is provided on the outer side surface of the upper end of the connecting piece 6, and an internal thread is provided on the inner side surface of the smoking channel of the smoking nozzle 1. The smoking nozzle 1 is rotatably locked on the connecting piece 6, and is sealed and fitted with the smoking nozzle through the first sealing ring 4 and the second sealing ring 5.

[0035] Reference Figure 2 and Figure 8 In order to enable the rotating seal 12 to rotate stably relative to the central tube 7 without moving up and down along the central tube 7, a first accommodating groove 1106 is provided on the bracket 11, and the rotating seal 12 is embedded in the first accommodating groove 1106. The end of the rotating seal 12 away from the bracket 11 is supported by the base 14 (in this embodiment, the rotating seal 12 and the base 14 are indirectly supported). Therefore, the rotating seal 12 can rotate stably relative to the central tube 7 in the first accommodating groove 1106.

[0036] In order to achieve the connection between the fan-shaped groove and the oil tank 17, the bracket 11 is provided with a second receiving groove 1105 above the first receiving groove 1106 (refer to Figure 8 ), the second accommodating groove 1105 and the first accommodating groove 1106 are in the shape of a stepped hole as a whole, the second accommodating groove 1105 is connected to the fan-shaped groove of the rotating seal 12 located in the first accommodating groove 1106, and the top surface of the second accommodating groove 1105 is provided with an oil inlet hole 1101, and the oil inlet hole 1101 is connected to the oil tank 17, thereby allowing the fan-shaped groove to be connected to the oil tank 17.

[0037] To prevent the smoke oil from flowing out of the gap between the rotating seal 12 and the first receiving groove 1106, the side and top surfaces of the rotating seal 12 are in sealing contact with the first receiving groove 1106. Specifically, an annular protrusion can be provided on the side and top surfaces of the rotating seal 12, and the annular protrusion fits tightly with the first receiving groove 1106.

[0038] In order to conveniently rotate and turn the rotating seal 12, a rotating switch 13 is further provided between the rotating seal 12 and the base 14. The rotating switch 13 is provided with a third through hole 1301 along its axis. The center tube 7 is inserted in the third through hole 1301, and the third through hole 1301 and the center tube 7 are loosely matched; one end of the rotating switch 13 is abutted against the base 14, and a column 1302 is provided at the end of the rotating switch 13 away from the base 14. In this embodiment, the column 1302 is an arc-shaped sheet, and a hole matching the column 1302 is provided at the end of the rotating seal 12 close to the rotating switch 13, and the column 1302 is inserted in the hole, so that the rotating switch 13 can conveniently drive the rotating seal 12 to rotate.

[0039] In order to facilitate the rotation of the rotary switch 13, the outer circumferential surface of the rotary switch 13 is provided with anti-slip stripes 1304. In order to make the connection state between the oil passage 1201 and the oil hole 72 intuitively identifiable outside the atomizer, a triangular mark 1303 is provided on the rotary switch 13, and a first mark 1102 with the word "ON" and a second mark with the word "OFF" are provided on the bracket. In the specific setting, the symmetric planes of the two adjacent oil inlet holes 1101 of the bracket 11 can be made to coincide with the axis of the oil hole 72 of the central tube 7 (at this time, the distance for the oil to flow from the oil tank 17 to the heating element 9 is the shortest, which can prevent the oil from not flowing to the heating element 9 in time and causing the atomizer to not produce smoke in time, thereby preventing the user from misjudging the electronic cigarette as having a fault), the center plane of the first mark 1102 coincides with the symmetric center planes of the two opposing pairs of oil holes 72, and the center plane of the triangular mark 1303 of the rotary switch 13 coincides with the symmetric center plane of the fan-shaped protrusion 1203 of the rotary seal 12. Thus, when the triangle mark 1303 is aligned with the first mark 1102, the oil hole 72 is completely connected with the oil passage 1201 (refer to Figure 3 and Figure 4 ), the smoke oil can fully and quickly penetrate into the heating element 9 to prevent the heating element 9 from burning dry or the smoke oil from burning due to insufficient smoke oil or insufficient penetration. When the triangle mark 1303 is aligned with the second mark (refer to Figure 5 and Figure 6 ), the fan-shaped protrusion 1203 completely blocks the oil hole 72, and the oil passage 1201 is not connected to the oil hole 72 to prevent oil leakage.

[0040] The first mark 1102, the second mark and the triangular mark 1303 can be produced by screen printing, laser engraving or water transfer printing.

[0041] In this embodiment, the heating element 9 is selected as a ceramic heating wire, and a non-woven fabric 8 is also arranged between the ceramic heating wire and the central tube 7. The non-woven fabric 8 can guide the oil entering through the oil hole 72 to the heating element 9 to prevent the oil from leaking from the base 14.

[0042] The heating element 9 is electrically connected to the electrode 16 , and an insulating member 15 is disposed between the electrode 16 and the base 14 .

[0043] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the creative spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
