Description

[Technical field]

[0001] The present invention relates to the technical field of atomization, and in particular to an exothermic atomization core. [Background technology]

[0002] In the field Heat generating atomization core are small in volume and generally use a battery with a voltage between 2 and 4V and a power of 6 to 20W to supply electricity. In addition, atomization by heating requires that the temperature reach over 200 degrees at the moment of inhalation. For this reason, the heating circuit of the heating element is generally thin, so the heating elements used in this field have poor strength and are very prone to deformation. In addition, the electrode lead wire extends and is connected to the battery, but if the electrode lead wire becomes unstable due to the force applied to it, the heating circuit of the heating element will also become unstable, resulting in poor contact between the conductor and the heating element. For this reason, there are very high requirements for transportation and assembly. In addition, if the electrode lead wire comes into contact with a metal part, Heat generating atomization core The inside of the device will short circuit.

[0003] In addition, currently being applied in the field Heat generating atomization core are mainly divided into cotton core and ceramic core. Cotton core is comfortable to draw, easy to obtain and lower cost. However, cotton core is weak in strength, not easy to support, and cannot achieve complete contact between the liquid conductor and the heating element, resulting in low atomization efficiency, incomplete atomization, leakage and other problems.

[0024] As shown in Figs. 1 to 7, the heat generating atomizing core includes a liquid guiding element 100, a heating element 200, and an electrode lead wire 600 connected to the heating element 200. The heating element 200 is in close contact with the surface of the liquid guiding element 100. The electrode lead wires 600 extend from both ends of the heating element 200 to the outside, and at least one of the electrode lead wires 600 is provided with an insulating coating 500. A housing 300 extending in the axial direction is provided on the outside of the liquid guiding element 100. The liquid guiding element 100 is filled in the housing 300 so as to be combined with the liquid guiding element 100. A fixing member 700 for fixing the electrode lead wire 600 is provided in the housing 300. The housing 300 extending in the axial direction is formed in the axial direction and restrains and supports the liquid guiding element 100 and the heating element 200 in the radial direction.

[0025] As shown in Figures 1 to 4, the main role of the housing 300 of the present invention is to protect and support the liquid guide 100 and the heating element 200. The shape of the housing 300 is adapted to the shapes of the liquid guide 100 and the heating element 200. The heating element 200 has an arc shape or a cylindrical shape. Correspondingly, the liquid guide 100 has a cylindrical structure, and the housing 300 also has a cylindrical structure.

[0026] The first embodiment of the housing 300 is as follows. That is, the housing 300 has a straight tube structure. Also, a liquid supply hole 310 or a liquid supply groove is provided on the side surface of the housing 300. The hole or groove provided on the side surface is used to control the contact area between the liquid and the liquid guide 100, thereby controlling the amount of liquid supply. Generally, one or two liquid supply holes 310 or liquid supply grooves are provided on the side surface of the housing 300.

[0027] The housing 300 is made of a metal pipe, a plastic pipe, a ceramic pipe, or the like. The housing 300 has relatively high requirements in terms of heat resistance, strength, and wall thickness, and is required to have high heat resistance, excellent strength, and a thin wall thickness, and low cost must also be considered. Therefore, it is preferable to use a metal pipe made of a metal material, for example, stainless steel or other metal, which is processed and then surface-treated.

[0028] The second embodiment is as follows: That is, the housing 300 has a cylindrical frame structure. The frame structure does not need to be provided with a liquid supply hole 310 or the like, and liquid can be supplied directly through the gaps in the frame.

[0029] As shown in Figs. 1 to 4, the liquid-guiding 100 is in close contact with the housing 300 inside the housing 300. The liquid-guiding 100 is filled inside the housing 300. As shown in Figs. 1 to 3, the liquid-guiding 100 may have a tubular structure of liquid-guiding cotton, or as shown in Fig. 4, the liquid-guiding 100 may have a multi-layered tubular structure manufactured by stacking a plurality of layers of liquid-guiding cotton. Multiple layers of liquid-conducting cotton The connection port is inserted into the engagement groove 320 provided in the housing 300. Since the liquid-permeable cotton is relatively soft and has a relatively low support, it is preferable to manufacture the liquid-permeable cotton cloth by stacking multiple layers. Compared with a cotton core, the uniformity and speed of liquid-permeable liquid are greatly improved when multiple layers of liquid-permeable cotton cloth are stacked.

[0030] As shown in Figures 1 to 4, the liquid guiding element 100 contains a heating element 200. The heating element 200 is made up of a central heating section and electrodes at both ends, and may be in the form of a sheet, a cylinder or a spiral. The sheet-like heating element 200 may be rolled up to form an open cylinder.

[0031] Electrode lead wires 600 are connected to the electrodes at both ends of the heating element 200. At least one electrode lead wire 600 is provided with an insulating coating 500. In the present invention, the insulating coating 500 is provided on the outside of the electrode lead wires 600 mainly to prevent a short circuit between the two electrode lead wires 600. Therefore, this technical effect can be achieved if one electrode lead wire 600 has insulation. Therefore, the electrode lead wire 600 having the insulating coating 500 may be one, or two electrode lead wires 600 may have the insulating coating 500. The installation position of the insulating coating 500 on the electrode lead wire 600 is required as follows. That is, since one end of the electrode lead wire 600 is welded to the heating element 200, the insulating coating 500 does not exist on the electrode lead wire 600 at the welded portion. On the other hand, the insulating coating 500 does not exist at least at the end of the portion extending from the housing 300, and it is necessary to connect it to a battery. Therefore, an insulating coating 500 is provided at least at the contact portion between the electrode lead wire 600 and the housing 300 .

[0032] By insulating with insulation coating 500, Electrode Lead Wire 600 This prevents the insulating coating 500 from coming into contact with the metal housing 300 and shorting out the inside of the heat-generating atomizing core. In addition, since the insulating coating 500 has a slight elasticity, it is sandwiched between the housing 300 and the fixing member 700, and can satisfactorily fix the electrode lead wire 600 without breaking it. Also, only a small amount of the conductive core wire is exposed from the end of the electrode lead wire 600. This prevents the electrode lead wire 600 exposed to the outside of the heat-generating member 200 from causing a short circuit, but it may be designed to be slightly longer so that it can be easily welded to an external battery.

[0033] As shown in Figs. 1 to 6, the electrode lead wire 600 needs to extend outside the housing 300 and be connected to the battery. However, if the electrode lead wire 600 is subjected to a force and becomes unstable, the heat generating circuit of the heating element 200 also becomes unstable, causing poor contact between the liquid conductor 100 and the heating element 200. For this reason, the electrode lead wire 600 needs to be fixed in advance by a fixing member 700. The center or lower part of the electrode lead wire 600 is bent and closely adheres to the inner wall of the housing 300. The fixing member 700 is packed into the housing 300 to fix the electrode lead wire 600. Specifically, the electrode lead wire 600 may be fixed by being sandwiched between the fixing member 700 and the inner wall of the housing 300, or the fixing member 700 may have a storage space. Since the electrode lead wire 600 is sandwiched between the housing 300 and the fixing member 700, the heat generating circuit of the heating element 200 within the housing 300 does not wobble due to the wobbling of the extended electrode lead wire 600.

[0034] The shape of the fixing member 700 fits and matches the shape of the inner wall of the housing 300 .

[0035] There are multiple embodiments of the securing member 700.

[0036] As shown in Figs. 1 to 4 and 6, the first embodiment is as follows. That is, a positioning groove 730 is opened on the outer periphery of the fixing member 700, and the electrode lead wire 600 is engaged and fixed in the positioning groove 730. The cross-sectional shape of the positioning groove 730 may be an arc shape, a U shape, a V shape, a rectangle shape, etc., but it is preferable that the positioning groove 730 has a V shape that has a large opening for easy insertion and can completely clamp and fix the electrode lead wire 600. The number of the positioning groove 730 is at least one. When one positioning groove 730 is provided, two electrode lead wires 600 are fixed together. Also, when two positioning grooves 730 are provided as shown in Fig. 6, the two electrode lead wires 600 are engaged in different positioning grooves 730. In addition, as shown in Fig. 3, a plurality of the positioning grooves 730 may be provided. The positioning grooves 730 are uniformly provided on the outer periphery of the fixing member 700, and the two electrode lead wires 600 are engaged in any two of the positioning grooves 730. A guide portion 720 is provided on the upper portion of the positioning groove 730. The guide portion 720 is smoothly connected from the ceiling surface to the positioning groove 730. Alternatively, the opening of the guide portion 720 gradually narrows from the ceiling to the bottom. The electrode lead wire 600 slides into the positioning groove 730 along the guide portion 720. In addition, the ceiling surface of the fixing member 700 is a slope or arc surface that is higher on the inside and lower on the outside. This is advantageous for sliding the electrode lead wire 600 to both sides, and the situation in which it is pressed against the ceiling surface of the fixing member 700 during assembly is avoided. In addition, the positioning grooves in the fixing member 700 730 Alternatively, the electrode lead wire 600 may be sandwiched between the fixing member 700 and the inner wall of the housing 300 without providing a fixing member 700. In this embodiment, the fixing member 700 may be an elastic member.

[0037] The second embodiment is as follows: The fixing member 700 has a through hole, and the electrode lead wire 600 is inserted into the hole.

[0038] The fixing member 700 is provided with a vent hole 710 that passes through the inside of the housing 300 and the outside of the housing 300. body It is possible to introduce air into 200. The shape and diameter of the ventilation hole 710 may be set according to actual needs, and are not limited here.

[0039] Heating element 200 and After the liquid guiding 100 is packed into the housing 300, the liquid guiding cotton and the heating element 200 are both fixed inside the housing 300 by the constraint of the housing 300. In addition, the heating element 200 is made of a metal material and has an outward elastic force, so that the contact between the heating element 200 and the liquid guiding 100 is good. In addition, when the fixing member 700 is packed into the housing 300, the electrode lead wire 600 is sandwiched between the housing 300 and the fixing member 700. Therefore, the heating circuit of the heating element 200 in the housing 300 does not wobble with the wobbling of the extended electrode lead wire 600. Therefore, the problem that the heating circuit also wobbles when the electrode lead wire 600 is subjected to a force is avoided, and the problem of poor contact between the liquid guiding 100 and the heating element 200 is solved.
