Technical Field

[0001] This utility model relates to the field of cast copper heater technology, specifically a waterproof and energy-saving cast copper heater. Background Technology

[0002] Cast copper heaters are electric heaters that use heating elements as heating bodies and high-quality copper materials as outer shells, formed by die casting or centrifugal casting. They have advantages such as fast heat transfer speed, long life, good heat preservation performance, strong mechanical properties, corrosion resistance, and resistance to magnetic fields.

[0003] Patent document CN213305780U discloses a cylindrical cast copper heating coil, which states that "in this utility model, the heating coil body is divided into two parts, upper and lower shells, which can be easily disassembled and maintained. The disassembly is simple and quick. Both upper and lower shells are equipped with water pipe structures. The water pipes and electric heating tubes are arranged alternately to increase their water cooling heat dissipation capacity. The heating coil can be quickly cooled by passing water through it."

[0004] However, the aforementioned cylindrical cast copper heating ring in the published literature mainly addresses the problem that existing heating rings are not easy to cool down quickly after use. However, the waterproofness of the circuit connection terminals in the cylindrical cast copper heating ring cannot be improved, which makes it easy for water to enter and cause short circuits.

[0005] In view of this, it is necessary to develop a waterproof and energy-saving cast copper heater, which can improve the waterproof effect of the cast copper heater. Utility Model Content

[0024] Please see Figures 1-4 A waterproof and energy-saving cast copper heater;

[0025] It includes: a first heater 1, a second heater 2, and a waterproof connection assembly. The first heater 1 and the second heater 2 are connected by a hinge. Two sets of waterproof connection assemblies are respectively installed on the front of the first heater 1 and the second heater 2. Liquid enters the circuit connection point between the first heater 1 and the second heater 2 through the waterproof connection assembly. The waterproof connection assembly includes a threaded connector 6, a sealing ring 7, a sealing gasket 8, a threaded sealing cylinder 10, and a sealing ring 11. The threaded connector 6 is installed on the front circuit connection end of the first heater 1 and the second heater 2. The sealing ring 7 is installed on the outer side of the connection end of the threaded connector 6. The sealing gasket 8 is installed on the outer side of the front of the threaded connector 6. The threaded sealing cylinder 10 is installed on the outer side of the threaded connector 6 through the thread. The sealing ring 11 is installed through the front of the threaded sealing cylinder 10. A connecting wire 9 is installed on the mating end of the threaded connector 6.

[0026] The first heater 1 and the second heater 2 are connected by a hinge at their backs, allowing their front sides to be opened and closed. To ensure the waterproof sealing of the circuit connection of the cast copper heater, a waterproof connection assembly is installed at the circuit connection end. The cast copper heater is connected to the connecting wire 9 through the circuit connection end on the front, enabling the cast copper heater to be powered on and heated. Since the threaded sealing cylinder 10 in the waterproof connection assembly is installed on the outside of the connecting wire 9 through the sealing ring 11, after one end of the connecting wire 9 is connected to the threaded connector 6, the threaded sealing cylinder 10 is rotated from one end of the front of the threaded connector 6 and installed on the outside of the threaded connector 6. During installation, the back of the threaded sealing cylinder 10 applies pressure to the sealing ring 7, and the inner wall of the front applies pressure to the sealing gasket 8, so that it can be sealed with the threaded connector 6, preventing liquid from entering through the gap between the threaded sealing cylinder 10 and the threaded connector 6. At the same time, the point where the threaded sealing cylinder 10 passes through the connecting wire 9 is sealed by the sealing ring 11, and the sealing ring 11 and the connecting wire 9 are fixed with waterproof sealant, thereby improving the waterproof effect of the circuit connection end of the cast copper heater.

[0027] Please see Figure 1 and Figure 5 A waterproof and energy-saving cast copper heater;

[0028] The system includes a positioning ring 13 and an insulation shell 4. A connecting plate 12 is symmetrically installed on the front of the threaded sealing cylinder 10, and the connecting plate 12 is located on the outer side of the front of the sealing ring 11. A positioning ring 13 is installed on the inner side of one end of the connecting plate 12. A fixing bolt 14 is installed through the top of the positioning ring 13. The first heater 1 and the second heater 2 have the same structure. Both the first heater 1 and the second heater 2 include a cast copper heating plate 3, an insulation shell 4 and an insulation pad 5. The insulation shell 4 is installed on the outer side of the cast copper heating plate 3. The insulation pad 5 is installed inside the insulation shell 4 and is located between the cast copper heating plate 3 and the insulation shell 4.

[0029] The positioning ring 13, installed via the connecting plate 12, is located outside the connecting line 9. After the threaded sealing cylinder 10 is installed, the connecting line 9 located inside the positioning ring 13 is fixed using the fixing bolts 14, thereby preventing the connecting line 9 from being pulled, which would affect the sealing effect between the sealing ring 11 and the connecting line 9. The cast copper heating plate 3 generates heat energy to heat objects after being powered on. In order to reduce heat loss during the use of the cast copper heater, a heat insulation pad 5 and a heat insulation shell 4 are installed on the outside of the cast copper heating plate 3. The heat insulation pad 5 and the heat insulation shell 4 provide heat insulation and also increase the energy efficiency of the cast copper heater.

[0030] The working principle is as follows: First, the first heater 1 and the second heater 2 are combined on the outside of the object. The circuit connection terminal on the front of the heater is connected to the connecting wire 9, so that the heater can be powered on. In order to prevent water from entering the circuit connection terminal and short-circuiting, a waterproof connection component is installed on the outside. The waterproof connection component can seal the threaded connection head 6 between the connecting wire 9 and the circuit connection terminal of the heater, thereby improving the sealing performance of the connection and making the heater more waterproof.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
