Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to a detachable heater. Background Technology

[0002] A heater is a device that raises the temperature of a substance, which can be a fluid or a solid. Essentially, it converts energy into heat energy, typically using electricity, gas, fuel oil, or steam to generate heat and transfer it to the target substance to bring it to the desired temperature. Heaters are widely used in industry, commerce, and homes.

[0003] Electric heaters are widely used in the heating industry. Due to the widespread use of electricity, electric heaters have a very high penetration rate. They achieve heating functions through electricity. However, when repairing an electric heater, the entire unit needs to be disassembled, which can lead to the drawback of secondary welding of components. This makes repairs inconvenient, and secondary welding can also reduce the lifespan of the entire electric heater.

[0004] Therefore, how to provide a detachable heater is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a detachable heater, which solves the problem that existing electric heaters require secondary welding of components during maintenance, leading to inconvenience and reduced lifespan.

[0006] A detachable heater according to an embodiment of the present utility model includes a heater body and a lower cover. The lower cover is tightly fitted to one side of the heater body. A bolt is provided on one side of the heater body. The bolt passes through the heater body and the lower cover and extends to the other side of the lower cover. A nut is threaded onto the surface of the bolt on the side of the upper cover away from the heater body. The side of the nut is fitted to the surface of the lower cover. A central shaft is provided on one side of the lower cover. A bellows and a flange are respectively provided on the surface of the central shaft. The flange is located at the end of the bellows away from the lower cover.

[0007] A guide tube is provided on one side of the heater body, and the central shaft is fixedly sleeved on the surface of the guide tube. A support rod is also provided on the heater body, with one end of the support rod passing through the guide tube and extending to the outside of the guide tube.

[0008] A copper pad is provided between the heater body and the lower cover.

[0009] The surface of the nut is provided with a connecting component for retaining the nut on the upper cover, and the other end of the connecting component is provided on the upper cover.

[0010] Each nut corresponds to a set of connecting components.

[0011] The connecting assembly includes a swivel, a connecting bearing, a buckle, a connecting rope, and a connecting post. The connecting bearing is fixedly sleeved on the surface of the nut. The swivel is set on the connecting bearing. The buckle is fixed on the side of the swivel. The connecting post is fixed on the upper cover near the nut. One end of the connecting rope is movably sleeved on the buckle, and the other end of the connecting rope is movably sleeved on the connecting post.

[0012] The connecting rope is an elastic rubber rope.

[0013] The beneficial effects of this utility model are:

[0014] By using bolts, nuts, and guide tubes, when a problem occurs with the heater, the top cover can be quickly opened by removing the bolts and nuts to inspect the heater body. Opening the top cover will cause the guide tube to move on the surface of the support rod, allowing the components on the top cover and the components on the heater body to move relative to each other, making the top cover easy to disassemble. This eliminates the need to disassemble the originally welded components and perform secondary welding operations, making the maintenance of the heater body more convenient and eliminating the need for secondary welding of the components on the heater body. This solves the problem of inconvenience and reduced lifespan caused by secondary welding of components during the maintenance of electric heaters in the prior art.

[0015] By setting up a connecting component, the nut is connected to the top cover. This way, the nut does not need to be placed separately after being removed from the bolt, as it will be integrated with the top cover, thus preventing the nut from being lost due to being placed separately.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Example 1

[0023] refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, a heater body 1 and a lower cover 2 are included. The lower cover 2 is tightly fitted to one side of the heater body 1. A copper gasket 8 is provided between the heater body 1 and the lower cover 2. A bolt 3 is provided on one side of the heater body 1. The bolt 3 passes through the heater body 1 and the lower cover 2 and extends to the other side of the lower cover 2. A nut 10 is threaded on the surface of the bolt 3 on the side of the upper cover away from the heater body 1. One side of the nut 10 is fitted to the surface of the lower cover 2. A central shaft 4 is provided on one side of the lower cover 2. A bellows 5 and a flange 6 are respectively provided on the surface of the central shaft 4. The flange 6 is located at the end of the bellows 5 away from the lower cover 2.

[0024] refer to Figure 1 , Figure 2 and Figure 3 A guide tube 11 is provided on one side of the heater body 1. The central shaft 4 is fixedly sleeved on the surface of the guide tube 11. A support rod 7 is also provided on the heater body 1. One end of the support rod 7 passes through the guide tube 11 and extends to the outside of the guide tube 11. During operation, the bolt 3 passes through the mounting hole on the heater body 1, and then the mounting hole on the upper cover is aligned with the heater body 1. The mounting hole on the upper cover is then fitted onto the bolt 3. The upper cover and the heater body 1 are then fixed together by the bolt 3 and the nut 10. The guide tube 11 is movably sleeved on the surface of the support rod 7. When the heater body 1 needs to be removed, the nut 10 must first be rotated to separate the nut 10 from the bolt 3. Then, the upper cover is moved away from the heater body 1 to separate the upper cover from the heater body. This allows the heater body 1 to be repaired. Moreover, the guide tube 11 and the surface of the support rod 7 are movable. Therefore, the movement of the upper cover will cause the guide tube 11 to move on the surface of the support rod 7. This eliminates the need to disassemble the welded parts and avoid secondary welding.

[0025] Example 2

[0026] refer to Figure 1 , Figure 2 and Figure 3In this embodiment, the surface of the nut 10 is provided with a connecting component 9 for retaining the nut 10 on the upper cover. The other end of the connecting component 9 is disposed on the upper cover. Each nut 10 corresponds to a set of connecting components 9. The connecting component 9 includes a swivel ring 12, a connecting bearing 13, a pull buckle 14, a connecting rope 15, and a connecting post 16. The connecting bearing 13 is fixedly sleeved on the surface of the nut 10. The swivel ring 12 is disposed on the connecting bearing 13. The pull buckle 14 is fixed on the side of the swivel ring 12. The connecting post 16 is fixed on the upper cover near the nut 10. One end of the connecting rope 15 is movably sleeved on the pull buckle 14. The other end of the connecting rope 15 is movably sleeved on the connecting post 16. The connecting rope 15 is an elastic rubber rope. During operation, when the nut 10 rotates, the swivel ring 12 rotates on the nut 10 through the connecting bearing 13. This makes it difficult for the nut 10 to rotate and drive the swivel ring 12 to rotate. When the nut 10 is separated from the bolt 3, there is no need to place the nut 10 separately. After the nut 10 is separated from the bolt 3, the connecting rope 15 and the connecting post 16 connect the nut 10 to the top cover. This makes it less likely for the nut 10 to be lost when placed separately. Moreover, when the top cover is connected to the heater body 1, the nut 10 can be quickly picked up and quickly connected to the bolt 3, which also speeds up the installation.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
