[0002] The ceramic heating coil is made of stainless steel shell, with a resistance wire inside the ceramic with high insulation and fire resistance, and then mechanically twisted into shape. It can be used after connecting to the power supply. It has the advantages of easy installation, high temperature resistance, fast heat transfer, etc. The working voltage is any value between 12V-380V.

[0003] The temperature of the traditional ceramic heating coil is high during use, and it is necessary to wait for it to cool down slowly after heating, which is very time-consuming and cannot meet the needs of users. At present, conventional ceramic heating coils often need to be removed and placed in a cooling device for cooling after they are finished working. On the one hand, the surface temperature of the ceramic heating coil is high after work, which can easily burn the operator. On the other hand, since the external circuit connection of the ceramic heating coil is complex, it is inconvenient to frequently remove it from the pipeline, so it needs to be improved. Summary of the invention

[0006] By adopting the above technical solution, when the ceramic heating coil in the present invention is in use, the control board body and the air-cooling board can be installed outside the ceramic heating coil by connecting the connecting block with the connecting rod, so that a pair of swing blocks are driven to swing by the control structure, and the pair of swing blocks drive the air-cooling board to swing in the air-cooling cavity, thereby increasing the air flow rate near the air-cooling cavity, further enhancing the cooling effect of the ceramic heating coil, and there is no need to disassemble the ceramic heating coil, improving the convenience of cooling the ceramic heating coil.

[0007] Optionally, the control structure includes a second control airbag, a second control airbag and a linkage device. A partition piece is arranged on the inner side wall of the control board body. The partition piece divides the interior of the control board body into a second cavity and a second cavity. The second control airbag is located in the second cavity. The side of the second control airbag away from the partition piece is connected to the linkage device. The second control airbag is used to control the movement of the linkage device. The second control airbag is located in the second cavity. The side of the second control airbag away from the partition piece is connected to the linkage device. A second air inlet hole is opened on the side wall of the control board body. The second air inlet hole is communicated with the second control airbag. A second air inlet hole is opened on the side wall of the control board body. The second air inlet hole is communicated with the second control airbag. A second sealing piece is arranged on the second air inlet hole. A second sealing piece is arranged on the second air inlet hole. The second sealing piece and the second sealing piece are controlled by the linkage device.

[0008] By adopting the above technical solution, when the ceramic heating coil in the present invention is in use, due to the increase in temperature near the ceramic heating coil, the hot air enters the second control airbag and the second control airbag through the second air inlet hole and the second air inlet hole. The second sealing piece and the second sealing piece are alternately opened under the action of the second control airbag and the second control airbag, so that the hot air alternately enters the second control airbag and the second control airbag. The second control airbag and the second control airbag drive the swing block to swing, thereby driving the air-cooling board to fan, and further cooling the periphery of the ceramic heating coil.

[0009] Optionally, the linkage device includes a second linkage rod, a second linkage plate, a second linkage rod, a second linkage plate, and a control link. The second linkage plate is disposed in the second cavity, and the second linkage plate is slidably connected to the side wall of the second cavity. The second linkage plate is fixedly connected to the side of the second control airbag away from the separator. The second linkage rod is disposed on the side wall of the second linkage plate, and the second linkage rod is connected to the second cover plate. The second linkage rod drives the second cover plate to move in a direction opposite to that of the second linkage plate; the second linkage plate is disposed in the second cavity, and the second linkage plate is slidably connected to the inner side wall of the second cavity. The second linkage plate is fixedly connected to the side of the second control airbag away from the separator. The second linkage rod is disposed on the side wall of the second linkage plate, and the second linkage rod is connected to the second cover plate.

The control link is disposed between the second cover plate and the second cover plate, and a pair of the swing blocks are disposed on both sides of the second cover plate and the second cover plate.

[0010] By adopting the above technical solution, with the structure of the first linkage rod, the second linkage plate, the second linkage rod, the second linkage plate, and the control link, when hot air is injected into the second control airbag, the second linkage plate moves away from the second control airbag, thereby controlling the second cover plate. Similarly, when the second cover plate is driven by the second linkage plate to move, the second cover plate is driven to move, and by connecting the second cover plate and the second cover plate through the control link, the alternate inflation of the second control airbag and the second control airbag can be realized, and further the controlled swing of the swing block can be realized.

[0011] Optionally, both the second linkage rod and the second linkage rod include a fixed portion and a moving portion. The fixed portion is connected to the side wall of the control plate body. The fixed portion is hollow inside, and a connecting cable is inserted into the portion. The moving portion is connected to the second linkage rod or the second linkage rod. The second linkage rod or the second linkage rod is connected to the connecting cable. One end of the connecting cable away from the second linkage rod or the second linkage rod is connected to the second cover plate or the second cover plate.

[0012] By adopting the above technical solution, when the second linkage plate moves away from the second control airbag, the fixed portion remains stationary, and the connecting cable moves with the movement of the moving portion in the direction of the movement of the second linkage plate. Since the fixed portion is disposed on the side of the second control airbag away from the second control airbag, when the moving portion moves, the connecting cable drives the second cover plate to move out of the second air inlet, so that air enters the second control airbag and air exits the second control airbag.

[0013] Optionally, an adjusting mechanism is provided on the side wall of the control board body. The adjusting mechanism includes an adjusting connecting rod, an adjusting collar, and an adjusting screw. The adjusting connecting rod is connected to the side wall of the control board body.

The adjusting screw is arranged in the adjusting collar. One end of the adjusting screw away from the adjusting connecting rod is rotatably connected with an adjusting block, and the adjusting block is connected to the side wall of the air-cooled plate.

[0014] By adopting the above technical solution, through the structure of the adjusting connecting rod and the adjusting collar, the distance between a pair of air-cooled plates can be adjusted, and further the size of the ceramic heating coil adapted between a pair of swing blocks can be changed, improving the overall applicability of the system.

[0015] Optionally, a fixing hole is opened on the side wall of the adjusting collar. A fixing rod is arranged in the fixing hole. The fixing rod is threadedly connected with the fixing hole. One end of the fixing rod close to the adjusting screw abuts against the side wall of the adjusting screw.

[0016] By adopting the above technical solution, when the operator changes the distance between a pair of swing blocks by rotating the adjusting screw, after the adjustment is completed, the operator can rotate the fixing rod again, so that the fixing rod rotates in the fixing hole, and further one end of the fixing rod inserted into the fixing hole abuts against the side wall of the adjusting screw, thereby increasing the connection stability between the swing block and the adjusting connecting rod.

[0017] Optionally, a connection hole is opened on the side wall of the connection block close to the control board body. The connecting rod is inserted into the connection hole. A fixing magnet is arranged at one end of the connecting rod inserted into the connection hole. An abutting magnet is arranged on the inner bottom wall of the connection hole. The fixing magnet and the abutting magnet are magnetically attracted to each other.

[0018] By adopting the above technical solution, by using the structure of magnetic attraction between the fixing magnet and the abutting magnet, the control board body can be detachably connected to the ceramic heating coil by magnetic force. Therefore, in the use scenario where the ceramic heating coil in the present invention does not need to be cooled during short-time heating, the control board body can be detached, improving the overall applicability of the system.

[0019] Optionally, a filter plate is inserted into the air exchange hole. Filter holes are penetrated on the side wall of the filter plate.

[0020] By adopting the above technical solution, through the structure of the filter plate, it is not easy for external dust to enter the air-cooled plate from the air exchange hole, thereby ensuring the cleanliness of the ceramic heating coil during the heating and cooling process.

[0021] In summary, the present invention includes at least one of the following beneficial effects: 1. When the ceramic heating coil in the present invention is in use, the control board body and the air-cooling plate can be installed outside the ceramic heating coil by connecting the connecting block with the connecting rod. Then, through the control structure, a pair of swing blocks are driven to swing, and the pair of swing blocks drive the air-cooling plate to swing in the air-cooling cavity, thereby increasing the air flow rate near the air-cooling cavity, further enhancing the cooling effect of the ceramic heating coil, and without the need to disassemble the ceramic heating coil, improving the convenience of cooling the ceramic heating coil.

[0022] 2. By adopting the structure where the fixed magnet and the connecting magnet attract each other magnetically, the control board body can be detachably connected to the ceramic heating coil by magnetic force. Thus, in the usage scenario where the ceramic heating coil in the present invention does not require cooling during short-time heating, the control board body can be disassembled, enhancing the overall applicability of the system.
