Specifically, the atomizing sleeve 21 has an atomizing cavity, and the heating element is specifically accommodated in the atomizing cavity, and heats the e-liquid entering the atomizing cavity when powered on; it is understandable that the heat generated by the heating element will be transferred to the atomizing sleeve 21 through heat conduction.

[0046] The atomizing sleeve 21 may be a columnar body with a first end and a second end disposed opposite to each other. The heat conductor 22 is in contact with the first end of the atomizing sleeve 21, so that the heat on the atomizing sleeve 21 is directly transferred to the heat conductor 22, thereby dispersing the heat on the atomizing sleeve 21 and avoiding the problem of scalding caused by heat concentration. In a specific embodiment, the atomizer 20 has a mouthpiece, and the second end of the atomizing sleeve 21 is an end facing the mouthpiece and can be connected to the mouthpiece.

[0047] Specifically, the material of the heat conductor 22 may be metal, such as brass; the heat conductor 22 made of metal has higher heat conduction efficiency than materials such as plastic or rubber, and can better disperse heat; of course, in other embodiments, the material of the heat conductor 22 may also be high thermal conductivity ceramics, and the present application does not impose any restrictions on this.

[0048] It should be noted that in the specific embodiments, see Figure 3 The atomizer 20 further includes an outer shell 23 which is sleeved on the outer sides of the atomizing sleeve 21 and the heat conductor 22 . During use, the user contacts the outer shell 23 of the atomizer 20 .

The first heat conductor 221 and the second heat conductor 222 may be integrally formed.

[0050] For details, see Figure 4 In one embodiment, the second heat conducting part 222 and the first heat conducting part 221 can both be hollow cylinders, the second heat conducting part 222 and the first heat conducting part 221 are axially connected and coaxially arranged, and the diameter of the first heat conducting part 221 is smaller than the diameter of the second heat conducting part 222. Specifically, a flange 223 is provided on the outer wall of the second heat-conducting part 222, and the side of the flange 223 away from the outer wall of the second heat-conducting part 222 is specifically abutted against the inner wall of the outer shell 23, and the flange 223 cooperates with the outer wall of the second heat-conducting part 222 and the outer shell 23 to form a first air channel; wherein, the flange 223 can be specifically integrally formed with the outer wall of the second heat-conducting part 222; one end of the first air channel is connected to the atomization chamber, and the other end is connected to the outside air, so that the outside air can enter the atomization chamber through the first air channel, thereby extending the flow path of the air on the second heat-conducting part 222, so that the air passing through the first air channel can take away as much heat from the second heat-conducting part 222 as possible, so as to achieve the purpose of further cooling; at the same time, the temperature on the second heat-conducting part 222 can be used to preheat the newly-incoming air, so as to improve the heat utilization rate of the heating element, and make the air inhaled by the user have a certain temperature, so as to avoid the influence of inhaling cold air on the user experience.

Of course, in other embodiments, at least one air inlet hole 225 may also be provided at a position of the atomizing sleeve 21 close to the heat conductor 22; specifically, the air vent is communicated with the outside air, the air inlet hole 225 is communicated with the atomizing chamber, one end of the first air duct is specifically communicated with the air vent to communicate with the outside air, and the other end is communicated with the air inlet hole 225 to communicate with the atomizing chamber.

[0052] In a specific embodiment, the flange 223 includes a plurality of arc-shaped protrusions arranged at intervals, and the plurality of arc-shaped protrusions and the inner wall of the outer shell 23 and the outer wall of the heat conductor 22 form a first air channel; specifically, the plurality of arc-shaped protrusions may be evenly distributed on the outer wall of the second heat conducting portion 222, or may be irregularly distributed on the outer wall of the second heat conducting portion 222, and the present application does not impose any restrictions on this.

[0053] In another specific embodiment, the flange 223 may be spirally shaped and is wound from one end of the second heat-conducting part 222 away from the first heat-conducting part 221 along the axial direction of the second heat-conducting part 222 to a position close to the first heat-conducting part 221; it can be understood that, in this embodiment, the first air duct is spirally wound from one end of the second heat-conducting part 222 away from the first heat-conducting part 221 along the outer wall of the second heat-conducting part 222 to one end close to the first heat-conducting part 221, that is, the first air duct is a spiral air duct.

[0054] Specifically, in this embodiment, since the path of the first airway is long, the user experiences greater inhalation resistance during inhalation. In order to extend the air flow path and reduce inhalation resistance to make inhalation smoother, a plurality of notches 226 may be further provided on the flange 223, and the plurality of notches 226 may be staggered in the axial direction of the second heat conducting portion 222. It is understandable that in this embodiment, see Figure 5 , Figure 5 A partial schematic diagram of the second heat-conducting portion provided in one embodiment of the present application; the flange 223 can be specifically divided into a plurality of arc-shaped flanges spaced apart along the axial direction of the second heat-conducting portion 222 by the notch 226, and the arc-shaped flanges are specifically inclined; a first sub-air channel is defined between two adjacent arc-shaped flanges; outside air can enter one of the first sub-air channels from the air vent, and can directly enter other first sub-air channels connected to the current first sub-air channel at the notch 226, which greatly shortens the air flow path and effectively reduces the suction resistance.

[0055] In another specific embodiment, see Figure 6 , Figure 6Partial schematic diagram of the second heat conducting part provided for applying for another embodiment; The flange 223 may specifically include a plurality of annular protrusions 223a arranged at intervals, and the plane where the annular protrusions 223a are located may be perpendicular to the axial direction of the heat conductor 22, that is, the annular protrusions 223a are arranged in a radial direction parallel to the heat conductor 22, so that the process difficulty coefficient can be reduced and the processing by the technicians can be facilitated; Specifically, in this embodiment, a first sub-airway is formed between two annular protrusions 223a arranged adjacent to each other in the axial direction of the second heat conducting part 222, and each annular protrusion 223a has at least one notch 226, so that the two adjacent first sub-airways are connected, so that the outside air can enter the atomizing chamber through each first sub-airway and the air inlet 225. Specifically, in order to extend the path of the air between the vent and the air inlet 225, the notches 226 on the two adjacent annular protrusions 223a can be misaligned. Of course, in other embodiments, the plane where the annular protrusion 223a is located can also be tilted toward the direction of the heat conductor 22.

[0056] Specifically, in this embodiment, a plurality of notches 226 may be further provided on each annular protrusion 223a, and the notches 226 on two adjacent annular protrusions 223a may be staggered to ensure that air has a certain length of flow path on the second heat conducting portion 222 while reducing air absorption resistance.

[0057] In specific embodiments, see Figure 3 , the atomizer 20 further includes a liquid storage chamber housing 24, which is specifically sleeved on the outside of at least the atomizing sleeve 21, and cooperates with the outer wall of the atomizing sleeve 21 to form a liquid storage chamber for storing liquid e-liquid, etc.; in a specific embodiment, the outer shell 23 is sleeved on the outside of the liquid storage chamber housing 24 and is spaced from the liquid storage chamber housing 24 to form a heat insulation space S, so as to reduce the heat conduction between the liquid storage chamber housing 24 and the outer shell 23 through the heat insulation space S, thereby reducing the temperature on the outer shell 23 and preventing the outer shell 23 from being hot.
