[0025] Furthermore, the opening and closing cover 8 includes a cover ring 9 and a silicone sealing ring 10. The silicone sealing ring 10 is installed on the cover ring 9. The cover ring 9 is screwed and fixed to the lower end of the sliding sleeve 6. The control connecting rod 4 is provided with a positioning step 11 for supporting the cover ring 9, so that when the control connecting rod 4 moves up and down relative to the mounting frame 5, the opening and closing cover 8 also moves up and down.

[0026] Furthermore, the mounting frame 5 includes a base frame 12 and a positioning slide 13. The base frame 12 is positioned and placed in the connecting pipe 2 and is provided with a plurality of drainage holes 20. The positioning slide 13 is fixedly connected to the base frame 12 and is provided with a slide groove 15 from its upper end surface. A positioning pin 16 is provided at the lower end of the control link 4. Specifically, a positioning rod 36 connected to the positioning pin 16 is provided at the lower end of the control link 4. The positioning pin 16 cooperates with the slide groove 15 so that the control link 4 can only move up and down under the drive of the switch device 3. The switch device 3 is installed on the upper end of the drain pipe 1 through the fixed cover 14.

[0027] Furthermore, the switch device 3 includes an inner rotating sleeve 17, an outer rotating sleeve 18, and a twisting cover 19.

[0028] like Figure 4 As shown, when in use, the utility model is connected to the bathtub through the connecting pipe 2, such as Figure 5 As shown, the connecting pipe 2 is connected and installed with the bathtub through a hose. When using this device, the drain hole in the bathtub does not need to be installed with a water opening and closing device, and it can be always open. When the bathtub is used to store water, the silicone sealing ring 10 in the opening and closing cover 8 forms a seal against the inner wall of the connecting pipe, and the water level in the drain pipe 1 will be level with the water level in the bathtub. The height position of the bottom of the float 7 is the height of the overflow in the bathtub. If the water level in the drain pipe 1 continues to rise, the float 7 will generate an upward buoyancy under the buoyancy of the water, thereby driving the opening and closing cover 8 to rise through the sliding sleeve 6, thereby opening the automatic overflow drainage mode, and the overflow water is drained from the connecting pipe.
