[0044] In this embodiment, a first mounting plate 111 is protruded from the edge of the upper surface of the upper shell 110, and the first pulley group is connected to the inner surface of the first mounting plate 111 and extends toward the middle of the upper shell 110; a second mounting plate 121 is protruded from the edge of the lower surface of the lower shell 120, and the second pulley group is connected to the inner surface of the second mounting plate 121 and extends toward the middle of the lower shell 120. Through the arrangement of the above structure, the first mounting plate 111 extends upward along the edge of the upper surface of the upper shell 110, which is convenient for the user to connect the first pulley group to the inner surface of the first mounting plate 111, and the first pulley group extends above the upper shell 110 toward the middle of the upper shell 110, which is convenient for the user to insert the first pulley group into the first slide rail 211; the second mounting plate 121 extends downward along the edge of the lower surface of the lower shell 120, which is convenient for the user to connect the second pulley group to the inner surface of the second mounting plate 121, and the second pulley group extends below the lower shell 120 toward the middle of the lower shell 120, which is convenient for the user to insert the second pulley group into the second slide rail 221, making it convenient for the user to load and unload the filter element.

Through the setting of the above structure, the first pulley 151 set on the left first mounting plate 111 corresponds one to one with the first pulley 151 set on the right first mounting plate 111, which can make the left and right sides of the upper shell 110 subject to uniform force, and the product structure is more stable; the second pulley 161 set on the left second mounting plate 121 and the second pulley 161 set on the right second mounting plate 121 correspond one to one, which can make the left and right sides of the lower shell 120 subject to uniform force, and the product structure is more stable.

[0051] In this embodiment, the edge of the upper housing 110 extends downward to form a first shielding plate 112, which at least partially shields the upper portion of the outer surface of the filter element 130. The edge of the lower housing 120 extends upward to form a second shielding plate 122, which at least partially shields the lower portion of the outer surface of the filter element 130.
