Detailed Description
The present invention will be described in detail below with reference to the drawings and detailed description.
Example 1
Referring to fig. 1 to 5, the present invention provides a dual heating structure heating component 100, which is applied to an electronic cigarette 200 to atomize tobacco tar of the electronic cigarette to form smoke. The dual heating structure heating component 100 comprises a first heating component 1, a second heating component 2 and an elastic connecting pipe 3, wherein the first heating component 1 and the second heating component 2 are both used for atomizing electronic cigarette tobacco tar. The electronic cigarette tobacco tar can contain propylene glycol, glycerol, essence, spice and the like. The essence and perfume can be coffee taste, peppermint taste, watermelon taste, blueberry taste or a combination of any two or more of the above. Of course, the e-cigarette tar may contain nicotine or the like, and may be selected as needed, and the chemical composition thereof is not particularly limited herein, as long as it can form smoke at the time of atomization.
The first heating component 1 comprises a first metal tube 11, a first porous oil guide plate 12, a first heating net 13 and a first conducting wire 14, wherein the first metal tube 11 is a steel tube, a first oil inlet notch 111 is formed in a first end of the first metal tube 11, and the first oil inlet notch 111 is arranged towards a first direction. The first porous oil guide plate 12 is guided and positioned through the first oil inlet notch 111 during assembly, and during operation, the electronic cigarette tobacco tar flows into the first metal tube 11 from the first oil inlet notch 111 and is adsorbed by the first porous oil guide plate 12.
The first porous oil guide plate 12 is installed in the first metal tube 11 and extends out from the first oil inlet notch 111, and the width of the end surface of the first porous oil guide plate 12 extending to the outside of the first metal tube 11 is larger than the width of the first oil inlet notch 111. The first oil inlet notch 111 includes a first guiding opening 112, a second guiding opening 113 and a clamping opening 114, the first guiding opening 112 is in end face communication with a first end of the first metal tube 11, a first end of the second guiding opening 113 is in communication with the first guiding opening 112, and a second end of the second guiding opening 113 is in communication with the clamping opening 114. The porosity of the end part of the first porous oil guiding sheet 12 extending to the outside of the first metal tube 11 is larger than the porosity of the rest of the first porous oil guiding sheet 12, so that tobacco tar can be guided into the first metal tube 11 as soon as possible, and the oil guiding efficiency is improved.
The first guide port 112 and the second guide port 113 gradually increase in a direction from the second end face of the first metal pipe 11 to the first end face of the first metal pipe 11. Therefore, when the first porous oil guide plate 12 is assembled, an operator does not need to worry about misalignment, and does not need to worry about excessive friction of the first oil inlet notch 111 on the first porous oil guide plate 12, and only the first end and the second end of the first porous oil guide plate 12 are simply pushed from the first guide opening 112 to the clamping opening 114, so that the assembly efficiency is improved.
The outer opening pitch of the second guide opening 113 is smaller than the inner opening pitch of the second guide opening 113, i.e., at the same radial position, the pitch of the second guide opening 113 at the outer circumferential surface of the first metal pipe 11 is smaller than the pitch of the second guide opening 113 at the inner circumferential surface of the first metal pipe 11. Therefore, during the assembly process, the side surface of the first porous oil guide plate 12 is not easily subjected to the friction force of the second guide opening 113, and the tilting caused by friction is avoided.
The orthographic projection of the first guide opening 112 on the longitudinal section of the first metal tube 11 is horn-shaped, and the orthographic projection of the second guide opening 113 on the longitudinal section of the first metal tube 11 is trapezoid-shaped. Therefore, during the assembly process, the side surfaces of the porous oil guide plate are not subjected to the friction force of the first guide port 112 and the second guide port 113, so that the problem that the liquid leakage is caused due to poor sealing performance caused by the fact that gaps are formed between the first porous oil guide plate 12 and the first metal tube 11 due to tilting caused by friction is avoided. It will be understood that the longitudinal section described in the present embodiment refers to a section perpendicular to the cross section of the first metal pipe 11 and perpendicular to the opening direction of the first oil inlet opening 111.
The clamping opening 114 is clamped on the first porous oil guide plate 12. The clamping opening 114 extends along the longitudinal direction of the first metal tube 11, and the orthographic projection of the clamping opening 114 on the longitudinal section of the first metal tube 11 is rectangular, so that the assembly is convenient, and the first porous oil guide plate 12 can be well clamped. The length of the clamping opening 114 is greater than that of the second guiding opening 113, and the width of the clamping opening 114 is smaller than that of the second guiding opening 113, so that the problems of low assembly efficiency and poor assembly caused by overlong length of the second guiding opening 113 are avoided.

The second end of the first metal tube 11 is provided with a first relief notch 116.
The first heating net 13 is located in the first metal tube 11 and contacts with the first porous oil guiding plate 12, and the first heating net 13 is provided with a plurality of polygonal heating rings 131. The first heating net 13 is wound in a cylindrical shape and is used for atomizing tobacco tar at the first porous oil guiding sheet 12. The first wire 14 is connected to the first heating network 13 and extends from the first metal tube 11. Wherein, the holes formed in the heating ring 131 are meshes of the first heating network 13, and the meshes may be diamond or other polygons.
