[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] Reference Figures 1 to 5The utility model proposes a tin melting furnace, including a shell 1 and a tin melting device 5, the shell 1 is formed with a accommodating cavity 2, the accommodating cavity 2 has an open end 3, a mounting seat 4 is arranged at the bottom of the accommodating cavity 2, and a plurality of mounting positions 41 are staggeredly arranged on the mounting seat 4; the tin melting device 5 includes a heating core 6 and a tin pot 7, the heating core 6 is fixed at the mounting position 41, the heating core 6 is electrically connected to an external power supply, the tin pot 7 is fitted on the inner wall surface of the heating core 6, and the plurality of mounting positions 41 can be used to install heating cores 6 and tin pots 7 of different sizes.

[0025] It can be understood that the interior of the accommodating cavity 2 is used to install the heating core 6 and the tin pot 7. A disc-shaped mounting seat 4 is arranged at the bottom of the accommodating cavity 2. The mounting seat 4 has many mounting positions 41. In this example, the mounting position 41 is a groove-shaped structure, which is used to fix the heating core 6. It should be noted that since the heating core 6 will generate heat when powered on, the mounting seat 4 should be made of high-temperature resistant material, such as ceramic, metal and other materials, which are not further limited here.

[0026] The heating core 6 is a ring-shaped structure, and its edge can be inserted into the installation position 41. Its working principle is similar to that of an electric soldering iron, and heat is generated through the resistance heating effect. When the heating core 6 is connected to an external power source, due to the resistance characteristics of the heating core 6, resistance will occur when current passes through, generating heat. This heat generated by the current passing through the resistance is the resistance heating effect; the tin pot 7 is a container for placing tin bars or other metals to be melted. It can be inserted into the middle of the heating core 6 of corresponding size and fit with the heating core 6. When the heating core 6 is powered on and heated, the heat is transferred from the heating core 6 to the tin pot 7, turning the metal in the tin pot 7 into a molten state. In addition to the above-mentioned devices, the tin melting furnace is also equipped with a temperature regulating device, a control device, etc., which are all existing technologies and will not be described in more detail here.

[0027] When replacing the tin pot 7 in the tin melting furnace, since the heating core 6 and the tin pot 7 need to be in close contact, the heating core 6 must also be replaced together. First, the heating core 6 is separated from the mounting position 41 on the mounting seat 4, and then the heating core 6 to be replaced is inserted into the corresponding mounting position 41, and the heating core 6 is connected to the power cord. Then, the tin pot 7 to be replaced is inserted into the circular ring formed by the heating core 6, so that the tin pot 7 and the heating core 6 are in close contact, and the replacement is completed. It should be noted that the sizes of different mounting positions 41, heating cores 6, and tin pots 7 should correspond to each other during the production process and be arranged in a matching manner to facilitate replacement.

[0028] Reference Figures 2 to 4 In one embodiment of the present application, a plurality of annular grooves 42 are staggeredly arranged on the mounting seat 4 to form a mounting position 41 .

[0029] It can be understood that the annular groove 42 is arranged corresponding to the annular heating core 6, so that the edge of the heating core 6 can be inserted and fixed in the annular groove 42 to achieve a better fixing effect. At the same time, multiple annular grooves 42 also form multiple ridges on the surface of the mounting seat 4. When the tin pot 7 is placed on the mounting seat 4, these ridges can effectively support the bottom of the tin pot 7.

[0030] Furthermore, the heating core 6 and the tin pot 7 can be made into a square or other shapes, and the mounting position 41 can be set as a square or other shaped groove corresponding to the heating core 6.

[0031] Reference Figures 2 to 4 In one embodiment of the present application, a plurality of annular grooves 42 are distributed in concentric circles, and the distance between any two adjacent annular grooves 42 is equal.

[0032] It can be understood that through the above-mentioned arrangement, on the one hand, the arrangement of the annular grooves 42 becomes beautiful, and the surface space distribution of the mounting seat 4 is reasonable with a clear sense of hierarchy; on the other hand, since a plurality of annular grooves 42 also form a plurality of ridges on the surface of the mounting seat 4, when the tin pot 7 is placed on the mounting seat 4, these ridges can evenly and effectively support the bottom of the tin pot 7, so that the structural strength of the mounting seat 4 is higher and the load-bearing capacity is stronger.

[0033] Reference Figure 2 and Figure 5 In one embodiment of the present application, a wiring portion 61 is provided on the surface of the heating core 6 .

[0034] It is understandable that the heating core 6 needs to be connected to an external power source to work properly. However, the heating core 6 also needs to be replaced during the replacement of the tin pot 7. Therefore, the wires cannot be fixed on the heating core 6. In this embodiment, a wiring portion 61 is provided on the surface of the heating core 6, which is connected to the wires through the wiring portion 61. When the heating core 6 needs to be replaced, it is only necessary to disconnect the wiring portion 61 from the wires, which will not affect the replacement of the heating core 6.

[0035] Reference Figures 1 to 5 In one embodiment of the present application, a baffle plate 8 is further provided on one side of the housing 1 where the open end 3 is located. A through hole 81 is formed on the baffle plate 8 , and an edge of the through hole 81 abuts against an outer wall of the tin pot 7 .

[0036] It is understandable that in order to facilitate the placement of the tin pot 7 from the open end 3 into the accommodating cavity 2, the size of the opening of the open end 3 will be larger than the size of the largest tin pot 7. Therefore, after replacing the smaller tin pot 7, a wider gap will be formed between the opening edge of the open end 3 and the tin pot 7, and the heating core 6 is in the gap, which has the risk of accidental touch and burns; and, since a layer of oxide film will be generated on the surface of the molten tin water during the tinning process, this oxide film needs to be scraped off first when tinning, and the scraped oxide film and tin water may fall into the gap, damaging the device and causing pollution. The baffle 8 is provided with a through hole 81 corresponding to the size of the tin pot 7, and the edge of the through hole 81 is against the outer wall of the tin pot 7, so that the gap between the opening edge of the open end 3 and the tin pot 7 is blocked, which avoids the risk of accidental touch of the heating core 6 on the one hand, which is safer, and prevents the tin water and oxide film from falling into the gap and causing pollution on the other hand.

[0037] Since the tin pot 7 has various sizes, the baffle 8 should also be made in multiple sizes corresponding to the tin pots 7 of different sizes. The through holes 81 on each baffle are of different sizes and are arranged in a matching manner with the heating core 6 and the tin pot 7. When the tin pot 7 is replaced, the corresponding baffle 8 is also replaced together.

[0038] Reference Figures 2 to 3 In one embodiment of the present application, the accommodating cavity 2 is at least provided with heat insulating cotton 21 at the bottom, and the mounting seat 4 is arranged on the heat insulating cotton 21 .

[0039] It can be understood that since the temperature of the heating core 6 is relatively high when it is working, the temperature of the mounting base 4 used to place the heating core 6 will also be relatively high. Laying insulation cotton 21 between the mounting base 4 and the inner wall of the accommodating chamber 2 can prevent high temperature from damaging the equipment and make personnel operation safer. In this example, the insulation cotton 21 covers the bottom and side walls of the entire accommodating chamber 2, making it more difficult for heat to spread to the equipment and increasing safety.

[0040] The technical solution of the utility model adopts a mounting seat 4 with multiple annular grooves 42 arranged inside the accommodating cavity 2. The multiple grooves can be used to install and fix heating cores 6 and tin pots 7 of different sizes. Tin pots 7 of different diameters can be easily replaced to meet different production needs and help save costs.

Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
