[0023] The use method of the utility model is as follows:
[0024] When the ground sewage needs to be discharged, the sewage flows into the water inlet groove 22 through the upper side of the water inlet groove 22, and then flows into the isolation seat 19 below through the upper filter hole 17; when the sewage flows through the upper filter hole 17, the upper filter hole 17 can intercept part of the impurities in the sewage through the hole diameter, and the first filtering is completed.
[0025] With the sewage flowing down, the water flow flows to the water passing hole 30 through the lower filter hole 16, because the upper filter hole 17 is coaxial with the water passing hole 30, therefore the sewage can flow to the lower side of the water passing plate 26 through the upper filter hole 17 and the water passing hole 30 in turn, and the lower filter hole 16 is smaller in diameter than the upper filter hole 17, therefore the lower filter hole 16 can further filter the small particle impurities in the sewage through the hole diameter, effectively avoiding the impurities in the sewage from contacting the opening and closing part 14, with the sewage flowing to the lower side of the water passing plate 26, the sewage pushes the upper surface of the opening and closing part 14 downwards, at this time, the opening and closing part 14 under pressure drives the sliding cover 10 to move downwards, when the sliding cover 10 moves downwards, the sliding cover 10 no longer blocks and seals the lower end hole of the opening and closing hole 6, the sewage can flow to the gap between the adjacent support arms 8 through the lower end hole of the opening and closing hole 6, and then flow into the sewage pipe through the gap between the adjacent support arms 8, to complete the sewage discharge work, when the sliding cover 10 moves downwards, the upper magnet block 13 moves downwards synchronously, the distance between the upper magnet block 13 and the lower magnet block 12 continuously decreases, and the repulsion force between the upper magnet block 13 and the lower magnet block 12 becomes larger, therefore when the sewage discharge is completed, the opening and closing part is reset under the repulsion force between the upper magnet block 13 and the lower magnet block 12, and blocks and seals the lower end hole of the opening and closing hole 6 again.
[0026] As described above, the upper blocking structure can first clean the large particle impurities in the sewage, and then the lower blocking structure can clean the small particle impurities in the sewage, effectively avoiding the impurities mixed in the sewage from pushing the opening and closing part 14, thereby avoiding the situation that the impurities in the sewage are accumulated on the upper surface of the opening and closing part 14, causing the opening and closing part to fail to block and seal the lower end hole of the opening and closing hole 6, effectively preventing the odor in the exhaust pipe from rising, and achieving the deodorization effect, and the upper blocking structure and the lower blocking structure can form two filtering, orderly filter the impurities in the sewage, avoid the situation that a large amount of impurities are simultaneously accumulated, causing the sewage to be difficult to flow normally, and ensure the one-way water outlet characteristic.
[0027] The outer wall of the boss 23 is provided with a plurality of anti-skid grooves 24 which are uniformly distributed in the axial direction, the anti-skid grooves 24 are annular, and the existence of the anti-skid grooves 24 can effectively increase the friction between the hand and the boss 23, so that the user can easily pull the isolation seat out of the valve body 1 by holding the boss, at this time, the large particle impurities trapped in the water inlet groove 22 can be ensured to be unobstructed through the upper filter hole 17.
[0028] The upper surface of the filter plate 33 is provided with a plurality of uniformly distributed screw holes 37, and a support rod 38 is screwed with the screw holes 37. The upper end of the support rod 38 is provided with a top plate 39 which is attached to the lower surface of the isolation seat 19. The support rod 38 is provided with a plurality of uniformly distributed blocking rods 40 from top to bottom. In the actual sewage discharge process, the sewage is easily mixed with hair and other strip-shaped impurities. When the sewage flows downward, the strip-shaped impurities in the sewage will be directly wound on the blocking rods 40 once they come into contact with the blocking rods 40. The presence of the blocking rods 40 can effectively prevent the strip-shaped impurities in the sewage from continuing to flow downward, further avoiding the occurrence of blockage.
[0029] When the isolation seat 19 is pulled upward, the filter plate 33 is directly exposed. At this time, the filter plate 33 can be pulled upward through the top plate 39 at the upper end of the support rod 38, so as to complete the disassembly of the filter plate 33. When the filter plate 33 is disassembled outside the one-way valve, small-particle impurities trapped on the upper surface of the filter plate 33 and strip-shaped impurities wound on the blocking rods 40 can be easily cleaned.
[0030] The outer wall of the valve body 1 is provided with a plurality of circumferentially uniformly distributed hidden grooves 41. The center of the groove bottom of the hidden groove 41 is provided with a threaded hole 42 which is in communication with the filter cavity 5. A screw 43 which is matched with the threaded hole 42 is screwed in the threaded hole 42. The inner end of the screw 43 abuts against the outer wall of the positioning pipe 15, and the head of the screw is located in the hidden groove 41. The head of the screw 43 and the groove bottom of the hidden groove 41 have a movable spacing 44. This fixing mode can effectively ensure the stability of the positioning pipe 15, and is beneficial to the disassembly and assembly of the positioning pipe 15. Since the head of the screw 43 is located in the hidden groove 41, the head of the screw 43 will not protrude out of the hidden groove 41 to affect the normal installation of the valve body.
[0031] The inner wall of the perforation 27 at the center of the water passage plate 26, the inner wall of the auxiliary pipe 28 and the outer wall of the sliding cover 10 all have a gap. Therefore, when the sliding cover 10 moves up and down along the trajectory of the guide rod 9, the sliding cover 10 can ensure smoothness. The outer wall of the auxiliary pipe 28 is provided with an auxiliary conical surface 29 which is narrow at the top and wide at the bottom. When the filter plate 33 is filtering, if a part of the impurities comes into contact with the auxiliary conical surface 29, the impurities will naturally slide downward along the auxiliary conical surface 29 under the action of gravity, so as to effectively prevent the impurities from entering the gap between the inner wall of the perforation 27 and the outer wall of the sliding cover 10.
