[0002] At present, the wall-mounted boiler is the best equipment for winter heating in most families in China and has a history of many years of use in China. However, since the heating water circuit is generally a closed circulating water circuit for long-term use, the water quality inside the water circuit is very poor and even contains a large amount of debris, which is likely to block the water circuit, resulting in a decrease in heat exchange efficiency, or causing the internal circulating water pump of the wall-mounted boiler to get stuck, posing a great potential safety hazard. Therefore, it is necessary to regularly replace the water inside the water circuit manually. This operation is very cumbersome, and it is impossible for manual labor to judge the appropriate replacement cycle. Therefore, it is usually replaced once in a heating season, but it is impossible to ensure that the water circuit does not get blocked during a heating season.

[0003] Therefore, there is an urgent need for an automatic cleaning device for a wall-mounted boiler to solve the above problems. Summary of the Utility Model

[0031] Optionally, a water pressure detection sensor 16 is further included. The water pressure detection sensor 16 is installed on the cleaning pipeline 11 or the hot water pipeline 22 and communicatively connected to the controller 15. After the sewage in both the hot water pipeline 22 and the cleaning pipeline 11 is drained, when the water pressure value detected by the water pressure detection sensor 16 is lower than a preset value, the water inlet valve 122 is opened, and the external water supply pipeline supplies water to the hot water pipeline 22 through the water inlet part 121.

[0032] Optionally, a housing 17 is further included. The cleaning pipeline 11, the sewage discharge assembly 13, the water quality detection sensor 14, and the controller 15 are all installed in the housing 17 to facilitate connecting the automatic cleaning device 1 to an existing wall-mounted boiler.
