[0049] Specifically, when the water pressure is reduced, the working principle is the same as above. At this time, the gravity of the gravity block 201 is downward, and the gravity block 201 moves downward under the pulling force of the spring 203. The downward movement of the spring 203 drives the gravity block 201 to move downward, and the downward movement of the gravity block 201 drives the connecting rod 204 to move downward, and the downward movement of the connecting rod 204 drives the rack 205 to move downward, and the downward movement of the rack 205 drives the first gear 206 to rotate, and the rotation of the first gear 206 drives the rotating rod 207 to rotate. The rotation of the rotating rod 207 is converted by the reducer 208, and at this time, it can drive the first threaded rod 209 to rotate, and then drive the slider 210 to move downward, and the downward movement of the slider 210 drives the second pipe 211 to move downward.
