The two sides of the main frame 4 are symmetrically fixedly connected to the limit frame 6, and the inside of the limit frame 6 is slidably connected to the rack 7. One end of the rack 7 is fixedly connected to the movable sleeve 3 through a connecting rod 14, and the movable sleeve 3 is slidably connected to the main frame 4 through a slider 8. The two racks 7 are symmetrical around the midpoint of the main frame 4. The inner side of the movable sleeve 3 is fitted with the through groove 10. The motor The output end of 9 can drive the gear 5 to rotate on the main frame 4, and the two racks 7 are respectively meshed with the two sides of the gear 5, and the limit frame 6 limits its moving trajectory to drive the two racks 7 to move linearly relative to each other, and the two racks 7 are connected to the movable sleeve 3 through the connecting rod 14, which can drive the two movable sleeves 3 to move linearly relative to each other on the outside of the shell 2. When the two movable sleeves 3 are close to each other, the area of ​​the movable sleeve 3 blocking the through groove 10 becomes larger, and the flow rate of tap water flowing out of the through groove 10 becomes smaller. When the two movable sleeves 3 are away from each other, the area of ​​the movable sleeve 3 blocking the through groove 10 becomes smaller, and the flow rate of tap water flowing out of the through groove 10 becomes larger.
