In the process of realizing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. Although the combined structure between the crushing device and the melting device effectively crushes the casting wax and facilitates the melting device to melt it, effectively reducing the melting time and greatly improving the melting efficiency, during use, in a traditional wax melting bucket, after crushing and then melting, since the heating mechanism is fixed in one position, the melting effect on casting wax at different positions is not uniform. Moreover, during the melting process of the casting wax near the bottom, it is easily affected by the bottom temperature, resulting in uneven melting of the casting wax at the bottom and the casting wax at the top. Therefore, it is necessary to design a new technical solution to solve this problem. Summary of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a wax melting bucket to solve the technical problems that in a current traditional wax melting bucket, after crushing and then melting, since the heating mechanism is fixed in one position, the melting effect on casting wax at different positions is not uniform, and moreover, during the melting process of the casting wax near the bottom, it is easily affected by the bottom temperature, resulting in uneven melting of the casting wax at the bottom and the casting wax at the top.

[0005] To achieve the purpose of the present utility model, the technical solution adopted by the present utility model is as follows: Design a wax melting barrel, including an outer barrel body, an inner barrel body is arranged inside the outer barrel body, a plurality of first crushing blades are fixed outside the inner barrel body, a plurality of second crushing blades are fixed inside the outer barrel body, and the plurality of second crushing blades are located between the plurality of first crushing blades;

[0009] Preferably, a circular shell is integrally formed at the bottom of the inner barrel body, and the circular shell is attached to the inner bottom surface of the outer barrel body.

[0010] Preferably, one end of a first connecting pipe is communicated with both the upper and lower sides of the front end of the outer barrel body, the other end of the first connecting pipe is detachably connected with a first pipe cover, both sides of the top of the inner barrel body are communicated with a second connecting pipe, and the top of the second connecting pipe is detachably connected with a second pipe cover.

[0011] Preferably, a control host is installed in the middle of the front end of the device bottom shell.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the combination of the inner barrel body, the first crushing blades and the cavity, water can be poured into the inner barrel body of the present utility model and heated by the electric heating tube. Since a cavity is provided inside the first crushing blade, the water will enter the cavity of the first crushing blade. After the water is heated by the electric heating tube, the heat can be quickly conducted to the plurality of first crushing blades. When the outer barrel body rotates to drive the second crushing blades to pass through the plurality of first crushing blades and crush the casting wax, the casting wax at different positions can be heated and melted, improving the melting effect of the casting wax, and solving the technical problem that in the traditional wax melting barrel, after crushing, melting is carried out. Since the heating mechanism is fixed at one position, the melting effect on the casting wax at different positions is not uniform.

[0014] 2. By combining the inner barrel body and the circular shell, the circular shell is integrally formed at the bottom of the inner barrel body. When the casting wax enters between the inner barrel body and the outer barrel body, the casting wax at the bottommost part will contact the circular shell. Since there is heated water inside the inner barrel body and the circular shell, it can pass around the circular shell to heat and melt the casting wax at the bottommost part, so that the melting effect of the casting wax at the top and the bottom is the same, solving the technical problem that the casting wax near the bottom is easily affected by the bottom temperature during the melting process, resulting in uneven melting of the casting wax at the bottom and the casting wax at the top.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present invention will be further described below with reference to the drawings and embodiments:

[0020] Embodiment 1: A wax melting barrel, see Figures 1 to 3, including an outer barrel body 205, an inner barrel body 201 is arranged inside the outer barrel body 205, a plurality of first crushing blades 204 are fixed outside the inner barrel body 201, a plurality of second crushing blades 206 are fixed inside the outer barrel body 205, and the plurality of second crushing blades 206 are located between the plurality of first crushing blades 204; a cavity 209 is formed inside the first crushing blade 204, and the cavity 209 communicates with the inner barrel body 201. An electric heating tube 2 penetrates through the top of the inner barrel body 201, and the electric heating tube 2 is fixed at the penetrating position of the inner barrel body 201. First, put the casting wax between the inner barrel body 201 and the outer barrel body 205. After putting the casting wax, turn on the motor 211. The motor 211 drives the motor shaft 212, and the motor shaft 212 drives the outer barrel body 205 to rotate. The outer barrel body 205 will drive the plurality of second crushing blades 206 to pass through the first crushing blades 204, thereby crushing the casting wax. During the crushing process of the casting wax, turn on the electric heating tube 2, and use the electric heating tube 2 to heat the water in the inner barrel body 201. Since the cavity 209 is arranged inside the first crushing blade 204, the water will enter the cavity 209 of the first crushing blade 204. After the electric heating tube 2 heats the water, the heat can be quickly conducted to the plurality of first crushing blades 204, so that during the crushing process of the casting wax, different positions of the casting wax can be heated and melted, improving the melting effect of the casting wax and solving the technical problem that in a traditional wax melting barrel, melting is carried out after crushing is completed. Since the heating mechanism is fixed at one position, the melting effect of the casting wax at different positions is not uniform.

[0021] Specifically, refer to Figure 1 , the top of the electric heating tube 2 is fixed with a device top plate 102, and both sides of the bottom of the device top plate 102 are fixed with support rods 101.

[0022] Furthermore, refer to Figure 3 , the bottom of the support rod 101 is fixed with a device bottom shell 1. A circular groove 210 is opened at the top of the device bottom shell 1. A motor 211 is installed at the bottom end inside the circular groove 210. The top of the motor 211 is connected with a motor shaft 212, and the top of the motor shaft 212 is fixed with an outer barrel body 205.

[0023] It should be noted that refer to Figure 2 , a circular shell 3 is integrally formed at the bottom of the inner barrel body 201, and the circular shell 3 fits with the inner bottom surface of the outer barrel body 205. When the casting wax enters between the inner barrel body 201 and the outer barrel body 205, the casting wax at the bottommost part will contact the circular shell 3. Since there is water heated by the electric heating tube 2 inside the inner barrel body 201 and the circular shell 3, the hot water will fill the inside of the circular shell 3 and can pass around the circular shell 3 to heat and melt the casting wax at the bottommost part, so that the melting effects of the casting wax at the top and the bottom are the same, solving the technical problem that during the melting process of the casting wax near the bottom, it is easily affected by the bottom temperature, resulting in uneven melting of the casting wax at the bottom and the top.

[0024] It should be noted that, referring to Figure 1 , one end of a first connecting pipe 207 is connected to both the upper and lower sides of the front end of the outer barrel body 205. The other end of the first connecting pipe 207 is detachably connected to a first pipe cover 208. Both sides of the top of the inner barrel body 201 are connected to a second connecting pipe 202, and the top of the second connecting pipe 202 is detachably connected to a second pipe cover 203.

[0025] It is worth introducing that, referring to Figure 1 , a control host 103 is installed in the middle of the front end of the device bottom shell 1.

[0026] When using a wax melting barrel, first put the casting wax between the inner barrel body 201 and the outer barrel body 205. After putting the casting wax, turn on the motor 211. The motor 211 drives the motor shaft 212, and the motor shaft 212 drives the outer barrel body 205 to rotate. The outer barrel body 205 will drive a plurality of second crushing blades 206 to pass through the first crushing blade 204, thereby crushing the casting wax. During the process of crushing the casting wax, turn on the electric heating tube 2, and use the electric heating tube 2 to heat the water in the inner barrel body 201. Since a cavity 209 is provided inside the first crushing blade 204, the water will enter the cavity 209 of the first crushing blade 204. After the electric heating tube 2 heats the water, the heat can be quickly conducted to the plurality of first crushing blades 204, so that during the process of crushing the casting wax, different positions of the casting wax can be heated and melted, improving the melting effect of the casting wax. When the casting wax enters between the inner barrel body 201 and the outer barrel body 205, the casting wax at the bottommost part will contact the round shell 3. Since there is water heated by the electric heating tube 2 inside the inner barrel body 201 and the round shell 3, the hot water will fill the inside of the round shell 3 and can pass around the round shell 3 to heat and melt the casting wax at the bottommost part, so that the melting effects of the casting wax at the top and bottom are the same.
