[0036] Specifically, the two heat insulation sleeves 201 can effectively prevent heat from dissipating outward, thereby ensuring that the temperature of the hot water flowing in the first conveying pipeline 202 is reduced as little as possible. The first conveying pipeline 202 can improve the water conveying efficiency. The support plate 203 provides a reliable supporting force for the upper box body 204. The box body 204 is stably placed on the support plate 203, and the circulation pipeline 205 is arranged in a winding shape inside the box body 204 to increase the residence time of the hot water therein and better achieve uniform distribution and exchange of heat.
[0037] Furthermore, one ends of the two first conveying pipelines 202 are respectively correspondingly connected to both ends of the circulation pipeline 205 to ensure that there is no leakage phenomenon during the hot water circulation process. These temperature monitors 206 monitor the temperature change of the hot water in the circulation pipeline 205. The first electric valves 207 can flexibly open or close the pipeline, accurately controlling the inflow and outflow of hot water and the circulation path.
[0038] The cleaning and heating mechanism 3 includes a support frame 302 fixedly installed inside the main frame 1. At one end of the support frame 302, a filter cylinder 301 is fixedly installed, and on both outer sides of the filter cylinder 301, bearing boxes 303 are fixedly installed.
