The structure inside the shell 10 is not shown in detail in the figure.

[0032] like Figure 2 、 Figure 3 and Figure 4 As shown, the filtering structure is detachably arranged in the cavity of the housing 10 for purifying water entering the cavity of the housing 10. The filtering structure includes a perforated plate 20, a built-in box 21 and a filter rod 22. The built-in box 21 is fixedly installed with the housing 10. The built-in box 21 can detachably install a plurality of filter rods 22. The perforated plate 20 is snap-fitted with the built-in box 21. Each filter rod 22 forms a filtering channel extending radially along the built-in box 21. The housing 10 forms a rectangular box body. The built-in box 21 is adapted to the cavity of the housing 10 and is fixedly arranged on the inner wall of the built-in box 21. The built-in box 21 is a rectangular block.

[0033] In this solution, a perforated plate 20 and a plurality of filter rods 22 are provided, and the water entering the chamber of the shell 10 is preliminarily filtered through the perforated plate 20, and then the water is further filtered through the plurality of filter rods 22, thereby achieving double treatment of the water and reducing the probability of water causing blockage of the pipeline and the heat pump.
