[0035] Specifically, please refer to Figure 1-Figure 2 The filter element (110) is cylindrical in shape as a whole. An upper end cover (111) is provided on the upper end surface of the filter element (110), and a lower end cover (112) is provided on the lower end surface of the filter element (110). The middle part of the filter element (110) is longitudinally penetrated to form a cavity. The UV lamp assembly (120) is fixed in the cavity to form a whole with the filter element (110).
