[0001] The present invention belongs to the technical field of dental instruments, and particularly relates to a gutta-percha heater for tooth filling. Background Art

[0002] In dental treatment, gutta-percha, as an important filling material, is widely used in tooth restoration and treatment. Especially in the root canal filling process after root canal treatment, the heating treatment of gutta-percha is an important step before its use. By heating, it can be softened, which is convenient for doctors to shape and tightly fill into the root canal of the tooth, thereby improving the quality and success rate of treatment;

[0003] Traditional gutta-percha heating methods mostly use a single heat source or a simple heating device, which have problems such as uneven heating, limited gutta-percha selection, and inconvenient operation, affecting the work efficiency and treatment experience of dentists. An ideal gutta-percha heater not only needs to have efficient and uniform heating capabilities, but also should be flexible to meet the heating requirements of different types and specifications of gutta-percha. At the same time, considering the actual working environment of dental clinics, the design of the heater also needs to take into account portability, ease of use, and space utilization. Therefore, the present invention proposes a gutta-percha heater for tooth filling. Summary of the Invention

[0004] The purpose of the present invention is to provide a gutta-percha heater for tooth filling to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A gutta-percha heater for tooth filling, comprising

Detailed Description of the Preferred Embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6, which is the first embodiment of the present invention. This embodiment provides a technical solution: a dental filling gutta-percha heater, including

[0030] a base 4, a support leg 2 welded and fixed to the top surface of the base 4, and a circular heating table 1 rotatably mounted on the top of the support leg 2;

[0031] An inner cavity 11 is formed inside the circular heating table 1, and an electric heating plate 12 is installed in the inner cavity 11. A power cord extends from the electric heating plate 12 to the outside of the circular heating table 1 and is connected to an external power supply. A plurality of heating cavities 13 are formed on the top surface of the circular heating table 1, and a metal heating tray 3 is placed in each heating cavity 13. In the later stage, different gutta-percha can be placed in different metal heating trays 3 for heating, which provides flexibility for medical staff. At the same time, due to the rotational design of the circular heating table 1, it can be placed between adjacent dental chairs in the dental clinic, saving space and facilitating shared use by multiple doctors without affecting each other's work;

[0032] A base sleeve 5 is welded and fixed to the bottom surface of the circular heating table 1, and the base sleeve 5 is rotatably sleeved on the top surface of the support leg 2. A disassembly and assembly structure 7 is provided between the support leg 2 and the base sleeve 5.

[0033] In this embodiment, preferably, a heat-conducting copper plate 14 is installed inside the bottom end of each heating cavity 13. A plurality of integral heat-conducting fins 15 are provided on the bottom surface of the heat-conducting copper plate 14, and the bottom ends of the heat-conducting fins 15 penetrate into the inner cavity 11. After the electric heating plate 12 is started later, the heat generated can be fully conducted to the heat-conducting copper plate 14 by the heat-conducting fins 15, and the heat-conducting copper plate 14 conducts the heat into the metal heating tray 3 to quickly heat the gutta-percha placed in the metal heating tray 3.

[0034] In this embodiment, preferably, the disassembly and assembly structure 7 includes two side movable plates 71 movably installed on the surface of the base sleeve 5. A limit clamping rod 72 is welded and fixed to the inner side of the bottom end of the side movable plate 71. An annular clamping groove 73 corresponding to the limit clamping rod 72 is formed on the top surface of the support leg 2. The end of the limit clamping rod 72 penetrates into the annular clamping groove 73 to realize the connection between the base sleeve 5 and the support leg 2. Since the annular clamping groove 73 is annular, the end of the limit clamping rod 72 will slide in the annular clamping groove 73 when the circular heating table 1 rotates later, realizing the smooth rotational installation of the circular heating table 1.

[0035] In this embodiment, preferably, the disassembly and assembly structure 7 further includes an inner sliding groove 74 formed inside the base sleeve 5. Two inner sliding seats 76 are slidably arranged in the inner sliding groove 74. A side connecting rod 77 is fixed to one side of each inner sliding seat 76. One end of the side connecting rod 77 penetrates through the surface of the base sleeve 5 and is fixed to the side movable plate 71, so that the side movable plate 71 can be smoothly pulled laterally. A spring 75 is also installed on the side surface of the inner sliding seat 76. Under the extrusion of the spring 75, the end of the limit clamping rod 72 can be stably located in the annular clamping groove 73 during daily use, ensuring the connection stability between the base sleeve 5 and the support leg 2.

[0036] In this embodiment, preferably, a circular groove for inserting the spring 75 is formed on the side surface of the inner sliding seat 76. One end of the spring 75 is inserted into the circular groove, and the other end of the spring 75 abuts against the inner wall of the inner sliding groove 74, so that the spring 75 can be limited to a certain extent to prevent deviation. A handle is fixed to the outer surface of the side movable plate 71, which is convenient for subsequent operators to laterally pull the side movable plate 71. When it is necessary to disassemble the circular heating table 1 from the support leg 2 later, the operator only needs to hold the handle and laterally pull the side movable plate 71, so that the side connecting rod 77 drives the inner sliding seat 76 to slide laterally and compresses the spring 75 until the end of the limit clamping rod 72 moves out of the annular clamping groove 73, and then the circular heating table 1 and the base sleeve 5 are no longer limited. At this time, the circular heating table 1 can be lifted to separate the base sleeve 5 from the support leg 2, quickly completing the disassembly between the circular heating table 1 and the support leg 2.

[0037] In this embodiment, preferably, a rubber bottom sleeve 6 is adhesively fixed to the bottom surface of the base sleeve 5, and the inner wall of the rubber bottom sleeve 6 is slidably attached to the outer surface of the support leg 2, so that when the base sleeve 5 rotates, the rubber bottom sleeve 6 will also rotate accordingly. An integral positioning protrusion 61 is provided on the inner wall of the rubber bottom sleeve 6, and both are made of rubber material and will undergo elastic deformation when being extruded. A plurality of positioning clamping grooves 21 corresponding to the positioning protrusion 61 are formed on the surface of the support leg 2. The positioning protrusion 61 is squeezed into one of the positioning clamping grooves 21. When the circular heating table 1 rotates later, the base sleeve 5 and the rubber bottom sleeve 6 will rotate together. As the rubber bottom sleeve 6 rotates, the positioning protrusion 61 will be continuously squeezed into the positioning clamping grooves 21 in other positions, so that the circular heating table 1 can be assisted in positioning to a certain extent after rotation and will not spin easily. When it is necessary to rotate the circular heating table 1, only need to rotate the circular heating table 1 forcefully so that the positioning protrusion 61 is squeezed and deformed and is extruded from the positioning clamping groove 21 at the current position.

[0038] Embodiment 2

[0039] Please refer to Figure 1To the figures, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that an inner wall of the heating cavity 13 is provided with a side groove 131, and a heat-resistant rubber seat 132 is embedded in the side groove 131. A rubber protrusion 133 integrated with the side of the heat-resistant rubber seat 132 is provided. Both are made of fluororubber material, which will undergo elastic deformation when being squeezed and have good heat resistance. The surface of the metal heating tray 3 is provided with an outer ring groove 31 corresponding to the rubber protrusion 133, and the rubber protrusion 133 is snapped into the outer ring groove 31, so that the metal heating tray 3 can be limited by the rubber protrusion 133 after being placed in the heating cavity 13, ensuring the installation stability of the metal heating tray 3. Subsequently, if the metal heating tray 3 needs to be taken out, only need to lift the metal heating tray 3 forcefully, so that the rubber protrusion 133 is extruded out of the outer ring groove 31, and the metal heating tray 3 can be successfully removed.

[0040] In this embodiment, preferably, the heat-resistant rubber seat 132 is in a C shape, so that the rubber protrusion 133 has sufficient deformation space when being squeezed, and the cross section of the rubber protrusion 133 is semicircular.

[0041] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
