[0040] The structure and use principle of the heater body 1, heating tube 2, power supply assembly 3 and cleaning assembly 4 in the present invention have been disclosed in a high-power and high-voltage electric heater disclosed in Chinese patent application number 202321377794.4. Its working principle is that in the process of using this heater, water is sent to the inside of the shell through the water inlet pipe, and one end of the power module wire is electrically connected to the power line, so that the heating tube 2 after power is turned on can heat the water, and the heated water will be discharged from the water outlet pipe to the inside of the shell. By starting the cleaning assembly 4, the scale generated on the surface of the heating tube 2 can be automatically cleaned. Under the action of the filter, the cleaned scale can be retained in the inside of the shell. When the cleaning assembly 4 is used, the starting motor drives the bidirectional screw to rotate. When the bidirectional screw rotates, it will drive the two cleaning plates to move in opposite directions. Because the cleaning plate slides on the surface of the heating tube 2, the scale on its surface can be cleaned.

[0041] Working principle and use process of the present invention: When the present invention is in use, the scale of the heater body 1 can be cleaned through the cleaning component 4, and the installation frame 7 is connected to the wall, and then the heater body 1 is placed on the connecting component 8, and then the clamping screw 83 is rotated. Under the action of the bearing 85 and the guide slider 86, the clamping plate 84 is driven to move, and the clamping plate 84 moves to clamp and fix the heater body 1. When removing, the clamping screw 83 is rotated in the opposite direction to release the limit on the heater body 1, and then the heater body 1 is removed from the positioning seat 81, so that when the device is in use, it is convenient to dismantle and repair the device when the heater body 1 has problems due to long-term use; when the device needs to be dismantled for maintenance, the heater body 1 can be quickly disassembled and assembled through the connecting component 8;

[0042] When it is necessary to discharge the cleaned scale, water is injected into the heater body 1, and then the scale is processed by the filtering circulation component 6 along with the water flow; when the filtering circulation component 6 is in use, the control valve 61 is opened to fill the heater body 1 with water, and the scale is accompanied by the water flow through the sewage pipe 5 into the purification box 62, filtered and adsorbed by the water filter 64 and the adsorption net 65, and then flows into the water collection tank 68, and finally the water in the water collection tank 68 is pumped out by the water delivery pump 69, and delivered to the heater body 1 through the water delivery pipe at one end of the water delivery pump 69, When it is necessary to clean the filtered scale, pull the limit rod 672, and the limit rod 672 drives the limit slider 673 to move the compressed limit spring 674, so that the limit rod 672 is separated from the limit hole above the sealing cover 66, and then the sealing cover 66 can be pulled to pull out the disassembly seat 63 placed in the purification box 62, and then take out the water filter 64 and the adsorption net 65 placed in the disassembly seat 63 for cleaning, so that when the device is in use, it is convenient to clean the scale and filter and purify the water discharged with the scale, so that the water can be recycled.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
