Examples
Referring to fig. 1 to 4, the present invention discloses a timing control device for water supply of a pneumatic control water supply valve, including a water storage tank 1, a three-way nozzle 2, a lever 3 and a float 4, the device is installed in a water storage tank 5 of a sink toilet in this embodiment, the top surface of the water storage tank 1 is slightly lower than the water level of the water storage amount set by a water inlet valve 51 of the water storage tank 5, the bottom surface of the water storage tank 1 is located at the middle upper part of the water storage tank 5, a water discharge amount hole 11 is arranged at the bottom of the water storage tank 1, the three-way nozzle 2 is arranged at one side above the water storage tank 1, the float 4 is arranged at the other side corresponding to the three-way nozzle 2 in the water storage tank 1, and the float 4 is controlled to float and fall through the water storage in the water storage tank 1.
One side of the three-way air tap 2 close to the floater 4 is provided with a lever support 8, the lever support 8 is provided with a rotating seat 81, the lever 3 is rotatably arranged on the rotating seat 81, one end of the lever is connected with the floater 4, the other end of the lever is used for jacking the first air tap 21 of the three-way air tap 2, and the lever length of one end of the lever used for jacking the floater 4 is larger than the lever length of one end of the lever used for jacking the first air tap 21. The first air nozzle 21 is arranged on the upper side of the three-way air nozzle 2, and a plug 31 is arranged at one end of the lever 3, which is used for jacking the first air nozzle 21, so that the first air nozzle 21 is better blocked, and the air tightness is improved.
The second nozzle 22 and the third nozzle 23 of the three-way nozzle 2 are respectively communicated with a pneumatic control water supply valve 6 and an air pressure generator 7 through hoses, and the air pressure generator 7 adopts an air pump.
A one-way valve 24 is arranged in the third air nozzle 23 and the air pressure generator room 7, and the air flow direction flows from the air pressure generator 7 to the three-way air nozzle 23, so that the air flow is prevented from flowing reversely.
When the water storage tank 5 of the sunken toilet is filled with water to reach the set height of the water inlet valve 51, the set height is higher than the top surface of the water storage tank 1, the water storage tank 1 is filled with water, the float 4 in the water storage tank 1 floats, the float 4 pushes one end of the lever 3 to move upwards, and the other end of the lever 3 moves downwards to push the plug 31 to press the first air nozzle 21 so as to plug the exhaust outlet of the three-way air nozzle 2.
