[0022] In this embodiment, the cleaning component can be used to clean the dust adhering to the surface of the heat exchange tube 4 to ensure its good working condition. Specifically, during cleaning, the output shaft of the drive motor 19 will drive the drive screw 20 to rotate, which in turn will drive the cleaning ring 17 to slide on the surface of the heat exchange tube 4 through the slide block 21 and the connecting bracket 18. The cleaning ring 17 can scrape off the dust on the surface of the heat exchange tube 4.

[0023] Preferably, a filter assembly is provided at one end of the inner cavity of the water tank 2. The filter assembly includes a filter cylinder 6 located at one end of the inner cavity of the water tank 2. An inner cylinder 7 is fixedly connected to the inner cavity of the filter cylinder 6. Through holes 8 are opened on the surface of both the filter cylinder 6 and the inner cylinder 7. A packing cavity 9 is provided between the filter cylinder 6 and the inner cylinder 7. The filter assembly is fixed to one end of the water tank 2 by a positioning assembly. The positioning assembly includes a positioning seat 13 fixedly installed at one end of the water tank 2.

During installation, the user can insert the main body of the filter cylinder 6 into the inner cavity of the water tank 2 through the positioning seat 13, and then twist the filter cylinder 6 so that one end is threadedly connected to the inner wall of the positioning seat 13, thereby threading the filter cylinder 6 to one end of the water tank 2. In this embodiment, a filter cavity is set between the filter cylinder 6 and the inner cylinder 7 for filling filter media. The incoming water first enters the inner cylinder 7, is filtered by the filter media, and then flows into the water tank 2 through the through hole 8 on the surface of the filter cylinder 6.

[0025] It is worth noting that a water inlet pipe 5 is provided on one side of the water tank 2. One end of the water inlet pipe 5 is connected to a backwashing component for flushing out the packing material in the filter assembly. The backwashing component includes a three-way pipe 10 connected to one end of the water inlet pipe 5. Two sets of control valves 11 are installed on the three-way pipe 10.
