[0018] Example

[0019] Combination Figure 1-3 As shown, a liquid electric heater that is easy to clean comprises a heater tank body 1, one side of which is detachably provided with a heating mechanism 2, through the setting of the heating mechanism 2, the liquid in the heater tank body 1 can be heated, and the other side of the heater tank body 1 is provided with a driving motor 5, the output end of the driving motor 5 extends to the inner cavity of the heater tank body 1 and is provided with a cleaning scraper 6 that fits with the inner wall of the heater tank body 1, through the setting of the driving motor 5 and the cleaning scraper 6, when the heater tank body 1 is cleaned, impurities attached to the inner wall of the electric heating tank body 1 can be scraped off, thereby improving the cleaning effect of the heater tank body 1, a reinforcing connecting block 7 is provided on the side of the cleaning scraper 6 close to the inner wall of the heater tank body 1, the reinforcing connecting block 7 and the cleaning scraper 6 are an integrally formed structure, and a liquid inlet pipe 4 connected to the heater tank body 1 is provided on the top of the heater tank body 1.

[0020] The protective cover 3 is detachably mounted on the outer side of the driving motor 5 , and the driving motor 5 can be protected by the setting of the protective cover 3 .

[0021] Among them, a reinforced connecting groove 8 is opened around the inner wall of the heater tank body 1 to allow the reinforced connecting block 7 to move. Through the arrangement of the reinforced connecting groove 8 and the reinforced connecting block 7, the scraping effect and scraping stability of the cleaning scraper 6 on impurities attached to the inner wall of the heater tank body 1 are improved.

[0022] like Figure 3The liquid inlet pipe 4 shown in the figure has a mounting plate 401 with a hollow cylindrical structure coaxially arranged in the liquid inlet pipe 4, and a plurality of limiting rods 402 uniformly distributed around the axis of the mounting plate 401 are arranged on the top end surface of the mounting plate 401, and the limiting rods 402 are connected to the mounting plate 401 by welding, and a filter sleeve 403 is detachably arranged in the liquid inlet pipe 4 at the top of the mounting plate 401, and the detachable connection between the filter sleeve 403 and the liquid inlet pipe 4 is provided, so that it is convenient for the staff to repair and replace the filter sleeve 403, and the filter sleeve 403 is provided with a filter screen 407 at both the upper and lower ends of the inner side of the filter sleeve 403, and the two filter screens 407 on the filter sleeve 403 can filter the liquid entering the heater tank body 1, so as to prevent impurities in the liquid from entering the heater tank body 1 and adhering to the surface of the heating tube and the inner wall of the heater tank body 1, so as to affect the subsequent use of the electric heater, and a limiting hole 404 for the limiting rod 402 to be inserted is opened through the filter sleeve 403.

[0023] Among them, a driving spring 405 is sleeved on the outer side of the limiting rod 402 at the bottom of the filter sleeve 403. Through the setting of the driving spring 405, the filter sleeve 403 can slide in the liquid inlet pipe 4 when it is impacted by the liquid, so as to prevent impurities on the filter screen 407 from rushing into the heater tank body 1. A threaded connection end 406 is provided on the limiting rod 402 at the top of the filter sleeve 403, and a fastening nut 408 is screwed on the threaded connection end 406. Through the setting of the threaded connection end 406 and the fastening nut 408, the filter sleeve 403 can be installed in the liquid inlet pipe 4 to be fixed and limited.

[0024] The working principle of the utility model is:

[0025] When in use, the liquid to be heated is first introduced into the heater tank body 1 from the liquid inlet pipe 4. The filter sleeve 403 in the liquid inlet pipe 4 can filter and intercept impurities in the liquid, thereby preventing the impurities from entering the heater tank body 1 and adhering to the surface of the heating tube and the inner wall of the heater tank body 1, affecting the subsequent use of the electric heater. When the filter sleeve 403 is impacted by the liquid, the driving spring 405 is compressed, causing the filter sleeve 403 to slide in the liquid inlet pipe 4, thereby preventing impurities on the filter screen 407 from rushing into the heater tank body 1.

[0026] When it is necessary to clean the inside of the electric heater tank body 1, firstly, clean water is injected into the electric heater tank body 1 through the liquid inlet pipe 4, and then the driving motor 5 is started to drive the cleaning scraper 6 to rotate, thereby scraping off impurities attached to the inner wall of the electric heating tank body 1, thereby greatly improving the cleaning effect of the inside of the electric heater tank body 1.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
