Further, the extending direction of the first linear air guiding portion 124a and the extending direction of the second linear air guiding portion 124b are both parallel to the extending direction of the air inlet channel, so that the smoothness of the air flow before and after being guided by the air guiding sheet 120 is improved.
As shown in fig. 3, in order to further improve the air intake smoothness of the electronic cigarette, in one embodiment, the connection between each linear air guiding portion 124 and the spiral air guiding portion 122 is in a round-angle transition, so that the air guiding transition at the connection between the linear air guiding portion 124 and the spiral air guiding portion 122 is smoother, the resistance of the air guiding sheet in the air guiding process is reduced, and the air intake smoothness of the electronic cigarette is further improved.
As shown in fig. 3, in one embodiment, the wind-guiding sheet 120 is an integrally formed structure, so that the structure of the wind-guiding sheet 120 is compact, and each linear wind-guiding portion 124 is firmly connected to the spiral wind-guiding portion 122. In the present embodiment, the connection between each linear air guiding portion 124 and the spiral air guiding portion 122 is rounded, and the air guiding sheet 120 is an integrally formed structure, that is, each linear air guiding portion 124 and the spiral air guiding portion 122 are integrally formed, so that each linear air guiding portion 124 and the spiral air guiding portion 122 are firmly connected, and the rounded structure at the connection between each linear air guiding portion 124 and the spiral air guiding portion 122 is easy to machine.
It is understood that in other embodiments, the wind-guiding plate 120 is not limited to be an integrally formed structure, i.e., each linear wind-guiding portion 124 is not limited to be integrally formed with the spiral wind-guiding portion 122. In one embodiment, each linear air-guiding portion 124 is welded or glued to the spiral air-guiding portion 122, that is, each linear air-guiding portion 124 and the spiral air-guiding portion 122 are formed separately and fixedly connected by welding or gluing, so that each linear air-guiding portion 124 and the spiral air-guiding portion 122 are firmly connected.
As shown in fig. 3 and 9, in one embodiment, the spiral air guiding portion 122 spirally surrounds the heat conducting sleeve main body 110, so that the area of the air flow contacting with the outer wall of the heat conducting sleeve main body 110 is larger in the process of guiding the air flow through the spiral air guiding portion 122, and the spiral air guiding portion 122 can better heat the air flow in the air guiding process.
Further, the heat-conducting sleeve main body 110 is cylindrical, a projection line of a connecting line of the spiral air-guiding portion 122 and the heat-conducting sleeve main body 110 on one end face of the heat-conducting sleeve main body 110 is a projection arc, and a circumferential angle corresponding to the projection arc is greater than 0 ° and smaller than 180 °, so that the situation that the spiral air-guiding portion 122 excessively guides and surrounds the air flow is avoided, and meanwhile, the spiral air-guiding portion 122 can better heat the air flow in the air-guiding process. In the embodiment, the circumferential angle corresponding to the projection arc is greater than 0 ° and less than 90 °, so that the situation that the spiral air guiding portion 122 excessively guides and surrounds the air flow can be better avoided, meanwhile, more spiral air guiding portions 122 can be arranged on the circumferential wall of the heat conducting sleeve main body 110, and the molding difficulty of a single spiral air guiding portion 122 is reduced.
As shown in fig. 10 and 11, in one embodiment, the heating mechanism 10 further includes a heating assembly 200, the heat-conducting sleeve body 110 has an accommodating cavity 112 along an axial direction, the heating assembly 200 is located in the accommodating cavity 112 and connected to the heat-conducting sleeve body 110, and the heating assembly 200 is configured to generate heat when energized. In the embodiment, when the conductive end of the heating assembly 200 is energized, the heating assembly 200 generates heat, and since the heating assembly 200 and the air guiding plate 120 are both connected to the heat conductive sleeve main body 110, the heat generated by the heating assembly 200 is respectively conducted to the heat conductive sleeve main body 110 and the air guiding plate 120. The air guide sheet 120 is connected to the periphery of the heat conducting sleeve main body 110, the air flow passes through the air inlet channel under the guiding action of the air guide sheet 120, and the heat of the air guide sheet 120 can be conducted to the air flow, that is, the air guide sheet 120 heats the air flow simultaneously in the process of guiding the air flow, and the air flow is heated after being guided by the air guide sheet 120.
Because the heating assembly 200 is positioned in the accommodating cavity 112 and connected with the heat conducting sleeve main body 110, heat generated by electrifying the heating assembly 200 can be conducted to the heat conducting sleeve main body 110, and heat of the heat conducting sleeve main body 110 can also be conducted to the air guide sheet 120, so that the heat of the heat conducting sleeve main body 110 can contact and heat the cigarette 300, meanwhile, the air guide sheet 120 exchanges heat with the air guide sheet 120 when guiding air flow, the air flow after heat exchange also acts on the surface of the cigarette 300 when contacting with the cigarette 300, and the heating mechanism 10 can uniformly heat the heat conducting sheet; because the heating element 200 is located in the accommodating cavity 112, the heating element 200 is accommodated in the heat conducting sleeve 100, so that the problem that the metal heating element is easily worn due to the fact that the heating element 200 is directly exposed outside is avoided, and the heating efficiency of the heating element 200 is improved. Because the air guide sheet 120 is located on the outer wall of the heat conduction sleeve main body 110 and connected with the heat conduction sleeve main body 110, the air guide direction of the air guide sheet 120 is the same as the axial direction of the heat conduction sleeve main body 110, and the accommodating cavity 112 is formed along the axial direction of the heat conduction sleeve main body 110, when the heat conduction sleeve main body 110 deviates from the position where the accommodating cavity 112 is formed and contacts with the cigarette 300, the air flow guided by the air guide sheet 120 cannot pass through the accommodating cavity 112, the problem of heavy metal pollution is avoided, and the use safety of the electronic cigarette is greatly improved.
In one embodiment, the accommodating cavity 112 is disposed on the same side of the heat-conducting sleeve body 110 and the air inlet end of the air-guiding sheet 120 in the air-guiding direction, so as to prevent the air flow from entering the accommodating cavity 112 under the guiding action of the air-guiding sheet 120, and further improve the safety of the electronic cigarette. In the present embodiment, the receiving cavity 112 is opened at an end surface of the heat conducting sleeve body 110. It is understood that in other embodiments, the receiving cavity 112 may be opened at other positions of the heat-conducting sleeve body 110, such as the receiving cavity 112 is opened at a side wall of the end portion of the heat-conducting sleeve body 110.
Further, a preset distance exists between the air inlet end of the air guiding sheet 120 in the air guiding direction and the end surface provided with the accommodating cavity 112, so that a distance exists between the part where the heat conduction sleeve main body 110 is connected with the air guiding sheet 120 and the end surface provided with the accommodating cavity 112, even if turbulent flow generated before the air flow is guided by the air guiding sheet 120 is blocked by the outer wall of the heat conduction sleeve main body 110 and then guided out by the air guiding sheet 120, the problem that the turbulent flow generated before the air flow is guided by the air guiding sheet 120 easily enters the accommodating cavity 112 is avoided. In this embodiment, the accommodating cavity 112 is opened at one end of the heat conducting sleeve main body 110, the accommodating cavity 112 extends inward from the end surface of the one end of the heat conducting sleeve main body 110 along the axial direction of the heat conducting sleeve main body 110, and the accommodating cavity 112 is a non-penetrating cavity structure along the axial direction of the heat conducting sleeve main body 110, so as to avoid the problem of heavy metal pollution in the air flow entering the accommodating cavity 112. It can be understood that an exposed portion not connected with the air guiding sheet 120 exists on the side wall of one end of the heat conducting sleeve main body 110, that is, a preset distance exists between the portion of the heat conducting sleeve main body 110 connected with the air guiding sheet 120 and the end surface of the end provided with the accommodating cavity 112. Turbulence may be created by the airflow being stopped by the air deflection sheet 120 before being directed by the air deflection sheet 120.
As shown in fig. 11, in one embodiment, the number of the air guiding sheets 120 is multiple, the air guiding sheets 120 are disposed at the outer circumferential wall of the heat conducting sleeve main body 110 at intervals, an air guiding channel 115 is formed between two adjacent air guiding sheets 120 and the heat conducting sleeve main body 110, and when the air flow is guided by the air guiding channel 115 and flows to the air inlet channel, the inner wall of the air guiding channel 115 heats the air flow, so that a certain amount of heat exists in the air flow flowing through the air guiding channel 115, and the heat conducting sleeve main body 110 can better heat the cigarette 300. Further, the plurality of air guiding sheets 120 are uniformly arranged along the outer circumferential wall of the heat conducting sleeve main body 110 at intervals, and the width of the air guiding channel 115 formed between two adjacent air guiding sheets 120 and the heat conducting sleeve main body 110 is equal, so that the air flow passing through the air inlet channel is relatively uniform.
As shown in fig. 2, in one embodiment, the heating mechanism 10 further includes a heat insulating sleeve 300, the heat insulating sleeve 300 is provided with a wind guiding channel 310, the heat conducting sleeve 100 is located in the wind guiding channel 310, and the wind guiding channel 115 is communicated with the wind guiding channel 310, so that the heating mechanism 10 is installed in the wind guiding channel 310 through the heat insulating sleeve 300, and the heat insulating sleeve 300 plays a role in heat insulation, thereby avoiding a problem of large heat loss on the heating mechanism 10, and improving heating performance and energy saving performance of the heating mechanism 10.
