Wherein, the way that passageway 103 rotated the case 101 of connecting the vertical setting can be: a circular mounting hole is formed in the vertical direction of the channel 103, the diameter of the mounting hole is larger than the front-back width of the channel 103, the height of the mounting hole is larger than the height of the channel 103, and the valve core 101 is configured in the mounting hole, so that the valve core 101 can rotate in the mounting hole.

The width dimension of the through hole 102 is smaller than the chord length dimension of the arc of contact between the valve core 101 and the mounting hole, so that when the through hole 102 and the channel 103 are in a vertical state, namely when the valve core 101 is in a closed state, two ends of the through hole 102 can be simultaneously wrapped by the mounting hole, and liquid can still pass through the valve core 101 when the valve core 101 is in the closed state.

Through the above structure, referring to fig. 1 and 3, when the through hole 102 and the channel 103 are in a parallel state, i.e. when the valve core 101 is in an open state, the valve core 101 is rotated by rotating the rotating shaft 104; when the through hole 102 and the channel 103 are in a space vertical state, the valve core 101 is in a closed state; when the filter element is normally used, the elastic piece 108 is in a compression state, the sliding block 107 is always contacted with the bottom of the filter element frame under the action of the elastic force of the elastic piece 108, the first fixing plate 110 is fixedly connected with the mounting groove 109 through a screw, the elastic force of the elastic piece 108 acts on the filter element frame through the sliding block 107 and enables the upper end of the filter element frame to be always contacted with the lower end of the second fixing plate 111, so that the filter element frame is positioned between the second fixing plate 111 and the sliding block 107, a sealing ring for preventing liquid leakage is arranged between the filter element frame and the sliding groove 106, and a gap for liquid circulation is arranged between the first frame 112 and the second frame 113, so that liquid can flow from one end of the channel 103 to the other end after being filtered by the filter element through the gap, and the liquid filtering effect is realized; when the filter element needs to be disassembled, referring to fig. 3, the fixing screws of the first fixing plate 110 and the mounting groove 109 are removed, the compressed elastic member 108 drives the sliding block 107, the filter element frame, the second fixing plate 111 and the first fixing plate 110 to move upwards, and the filter element frame can slide out from the sliding groove 106, referring to fig. 2, since the placing groove 117 has a certain distance from the front and rear end faces of the first frame 112 and the second frame 113, it can be avoided that impurities on the filter element are retained inside the channel 103 by the sliding groove 116 when the filter element frame is taken out. Meanwhile, because the sliding block 107 is in the pop-up state under the action of the elastic element 108, the height of the sliding block 107 is higher than the lower side surface of the channel 103, impurities in the liquid cannot enter the lower end position of the sliding groove 116, and the sliding block 107 is prevented from being influenced to slide up and down; since the bottoms of the first frame 112 and the second frame 113 are hinged to each other, the second frame 113 can be rotated around the hinge shaft 116 by the second hinge block 115, at this time, the dimension of the left-right direction of the upper ends of the first frame 112 and the second frame 113 is larger than the dimension of the left-right direction of the lower ends of the first frame 112 and the second frame 113, that is, the upper end of the filter element frame is in an open state, the filter element can be taken out from the placing groove 117, the second frame 113 is rotated after the filter element is replaced, the vertical directions of the first frame 112 and the second frame 113 are in a parallel state, and the first fixing plate 110 and the mounting groove 109 are re-fixed by placing the filter element into the sliding groove 106; the filter element frame is taken out to replace the filter element, so that the convenience of filter element replacement is improved, and the problem that the filter element is difficult to take out due to the fact that the filter element is deformed after being soaked in water for a long time is solved. Since one end of the adjusting block 120 is screwed to the upper position of the left end surface of the second frame 113 and the other end of the adjusting block 120 is movably contacted with the upper position of the right end surface of the first frame 112, adjusting the distance of the adjusting block 120 relative to the second frame 113 can adjust the relative distance between the upper sides of the first frame 112 and the second frame 113, and ensure that the first frame 112 and the second frame 113 are parallel to each other. The hand wheel 105 is movably clamped with the rotating shaft 104, so that the hand wheel 105 can be clamped on the rotating shaft 104 when the rotating shaft 104 needs to be rotated, and the hand wheel 105 can be taken down from the rotating shaft 104 when the rotating shaft 104 does not need to be rotated, so that the problem that the working position of the valve core 101 is changed due to the fact that the hand wheel 105 is rotated by misoperation is solved.
