Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present utility model, it needs to be understood that the orientations or positional relationships indicated by "top", "bottom", "above", "below", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0028] In order to prevent the wax melting tank from falling out of the shell when the denture processing wax melting device is placed upside down, the utility model provides a denture processing wax melting device, such as Figure 1-4 As shown, the denture processing wax melter includes a shell 1, a wax melting tank 2, a C-shaped retaining spring 3 and a heating device 4.

[0029] The shell 1 is a cavity structure with an opening at the top, and is used for installing the wax melting tank 2.

[0030] The wax melting tank 2 is a single-slot wax melting tank made of aluminum alloy with a fast heat transfer speed. The wax melting tank 2 is cylindrical with an open top for containing solid or liquid wax. The wax melting tank 2 is embedded in the shell 1, and the wax melting tank 2 is bent outward near the slot to form a horizontal bending portion 21, and the lower part of the bending portion 21 abuts against the upper surface of the shell 1.

[0031] An annular groove 22 is circumferentially formed on the outer wall of the wax melting tank 2 . The annular groove 22 is close to the bending portion 21 . The C-shaped retaining ring 3 is clamped in the annular groove 22 , and the top of the C-shaped retaining ring 3 abuts against the upper surface of the shell 1 .

[0032] The heating device 4 is made of a PTC ceramic heating plate and is disposed at the bottom of the wax melting tank 2 to heat the wax melting tank 2 so as to melt the wax contained in the single-slot wax melting tank 2 .

[0033] The C-shaped retaining ring 3 and the bent portion 21 of the wax melting tank 2 clamp the wax melting tank 2 and the housing 1 together to prevent the wax melting tank 2 from axially moving up and down.

[0034] In order to facilitate the installation of the C-shaped retaining ring 3, the shell 1 of this embodiment is divided into two parts, including an upper shell 11 and a lower shell 12. The upper shell 11 and the lower shell 12 are detachably connected, preferably threadedly connected, and the wax melting tank 2 is embedded in the upper shell 11.

[0035] In order to prevent the wax melting tank 2 from shaking left and right, a recessed stepped hole 13 is provided on the top of the upper shell 11 of this embodiment. The wax melting tank 2 is embedded in the stepped hole 13, and the bent portion 21 of the wax melting tank 2 abuts against the inner wall of the stepped hole 13.

[0036] In order to prevent heat from being transferred to the shell 1 and damaging the shell, the present embodiment further includes a heat insulating gasket 5, which is sleeved on the outside of the bent portion 21 and located between the bent portion 21 and the stepped hole 13. The heat insulating gasket 5 blocks the heat conduction between the wax melting tank 2 and the shell 1, preventing heat from being transferred to the shell 1.

[0037] In order to prevent dust from entering the wax melting tank 2, the present embodiment further includes an upper cover 6, which is rotatably mounted on the top of the upper shell 11. The upper cover 6 is selectively arranged on the top of the wax melting tank 2 to prevent dust from contaminating the wax water.

[0038] In order to control the temperature of the heating device 4, the present embodiment further includes a temperature sensor 7. The bottom of the wax melting tank 2 is provided with a receiving groove 23 and a fixing hole 24. The receiving groove 23 is in a straight line shape and is located in the center of the bottom of the wax melting tank 2. The shape of the heating device 4 matches the shape of the receiving groove 23. The heating device 4 is embedded in the receiving groove 23. The heat emitted by the heating device 4 is absorbed by the single-slot wax melting tank 2 to a greater extent, thereby improving the heat conduction efficiency. The temperature sensor 7 is embedded in the fixing hole 24. A cover plate 8 is provided on the top of the receiving groove 23, and the cover plate 8 is detachably connected to the bottom of the wax melting tank 2, preferably by bolts.

[0039] In order to facilitate the adjustment of the heating temperature, a temperature adjustment button 9 and a temperature display screen 10 are provided on the top of the upper shell 11 of this embodiment. The temperature adjustment button 9 is used to select the temperature of the wax melting, thereby preventing the wax water temperature from being too high or too low and affecting the quality of the wax mold, thereby reducing the failure rate of cast dentures; the temperature sensor 7 can sense the temperature of the wax water in the single-slot wax melting tank 2 in real time, and display it in real time through the temperature display 10, thereby facilitating the operator to judge the timing of wax melting.

[0040] Specifically, a control module 14 is disposed in the lower housing 12 , and the heating device 4 , the temperature sensor 7 , the temperature adjustment button 9 and the temperature display screen 10 are all electrically connected to the control module 14 for facilitating temperature control.

[0041] Specifically, a plurality of heat dissipation holes 15 are provided at the bottom of the lower shell 12 to dissipate heat. The heat dissipation holes 15 are located directly below the heating device 4 to protect the denture processing wax melter.

[0042] Specifically, a plurality of rubber pads 16 , preferably four rubber pads 16 , are provided at the bottom of the lower shell 12 to support the shell 1 .

[0043] Specifically, it also includes a power module 17, which is electrically connected to the control module 14. The power module 17 is arranged in the lower shell 12 to provide power support for the denture processing wax melter.

[0044] During installation, first put the insulation gasket 5 on the bent part 21 of the wax melting tank 2, then put the wax melting tank 2 into the stepped hole 13 of the upper shell 11, and then insert the C-shaped retaining ring 3 into the annular groove 22 to connect the wax melting tank 2 and the upper shell 11 together to prevent the wax melting tank 2 from falling out of the shell 1 when the denture processing wax melter is inverted.

[0045] The heating device 4 and the temperature sensor 7 are installed at the bottom of the wax melting tank 2, the control module 14 and the power module 17 are installed in the lower shell 12, and then the upper shell 11 and the lower shell 12 are bolted together.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
