[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention. Example

[0034] See also Figure 2-4 As shown, a heating structure of a hot gutta-percha is composed of a gutta-percha heating body 1 and a heating body 4. The gutta-percha heating body 1 has a heating cavity 101 for placing the gutta-percha; the periphery of the gutta-percha heating body 1 is provided with a heating body 4, and the heating body 4 is detachably arranged on the gutta-percha heating body 1. When the heating body 4 is assembled on the gutta-percha heating body 1, the heating body 4 is in surface contact with the outer surface of the gutta-percha heating body 1, so as to realize heat conduction between the heating body 4 and the gutta-percha heating body 1.

[0035] In this embodiment, the heating element 4 is composed of a sleeve 403 made of a high temperature resistant material and a heating structure, the heating structure is sealed inside the sleeve 403, and the lead 401 of the heating structure is exposed outside the sleeve 403. From the appearance of the heating element 4, the exposed lead 401 can be directly seen, and the built-in heating structure cannot be seen, which has good aesthetics.

[0036] The heating structure may be a heating wire or a heating sheet. When the lead wire 401 is energized, the heating element 4 will generate heat and transfer the heat to the gutta-percha heating element 1 through surface contact, thereby realizing the hot gutta-percha operation.

[0037] Specifically, the heating element 4 is made of high temperature resistant ceramics or other materials to seal the heating structure inside and pull out two lead wires 401 .

[0038] Of course, in addition to the heating structure being built inside and outside the sleeve 403, the heating structure can also be arranged on the inner surface of the sleeve. In this state, the heating structure will be exposed in the sleeve hole 402, and part of the heating structure will directly contact the gutta-percha heating body 1, and the heat conduction efficiency will be higher.

[0039] When in use, you only need to put the heating element 4 on the gutta-percha heating element 1. The gap between the heating element 4 and the gutta-percha heating element 1 can also be filled with a highly thermally conductive material such as thermal grease to form a thermal conductive medium layer, thereby further improving the heating efficiency.

[0040] Of course, in addition to the above-mentioned method of filling the heat-conducting medium to install the heating element 4 on the gutta-percha heating element 1, the following structure can also be used:

[0041] When the heating element 4 is sleeved on the teether heater 1 and the gap between the heating element 4 and the teether heater 1 is matched, the inner diameter of the heating element 4 can be designed to be narrow at the top and wide at the bottom, so that the heating element 4 can be directly snap-fitted and positioned on the teether heater 1; or the shape of the teether heater 1 can be designed to be narrow at the top and wide at the bottom, so that the heating element 4 can be directly snap-fitted and positioned on the teether heater 1; or a retaining edge can be directly provided on the periphery of the teether heater 1 so that the heating element 4 can be placed on the retaining edge.

[0042] The heating element 4 needs to conduct heat to the gutta-percha heating element 1. On the basis that the heating element 4 is upwardly detachable, the gap between the assembled heating element 4 and the gutta-percha heating element 1 can be reduced as much as possible to reduce heat loss.

[0043] The heating element 4 in this embodiment uses high temperature resistant ceramic as the heat conducting medium, which has high thermal conductivity compared to traditional polyimide, and the heating element 4 and the gutta-percha heating element 1 are in surface contact, so the heating efficiency is high. Since the ceramic can withstand high temperatures of several thousand degrees without decomposition, the heating element 4 can be used for a long time without the risk of decomposition, and has a long life. At the same time, the ceramic is strong, durable, high temperature resistant and highly insulated without the risk of insulation breakdown, and the safety risk is low. When there is a problem with the product and after-sales maintenance is required, the heating element can be directly removed and replaced without replacing the entire heating structure, which is convenient for after-sales maintenance.
