[0042] A water inlet is provided at the bottom of the water inlet valve 4, and a water flow channel is provided horizontally inside the water inlet valve 4. Clean water flows into the inside of the water inlet valve 4 from bottom to top from the water inlet and flows in the water flow channel. An air inlet is provided at the water outlet interface 13 of the water inlet valve 4, and a positioning sleeve 7, a water stop pad 14 and a water stop cover 15 are provided at the air inlet in sequence from the inside to the outside. The positioning sleeve 7 is a cylindrical structure with a notch on the front side, the notch is opposite to the water outlet interface 13, and the positioning sleeve 7 is sleeved on the end of the water flow channel; the left end of the water stop cover 15 is installed on the air inlet, one end of the water stop pad 14 abuts at the end of the water flow channel, and the other end of the water stop pad 14 abuts on the water stop cover 15; a fixed clamp ring 18 is fixedly installed on the right end of the water stop cover 15, and a switch movable Plug 10, air nozzle 11, air pipe 12 and air bag 17, the switch movable plug 10 is slidably installed on the left side of the air bag 17, and the switch movable plug 10 is fixedly connected to the left end of the water stop cover 15 through the reset spring 9, and a water stop pad inner cavity is formed inside the water stop cover 15 between the water stop pad 14 and the switch movable plug 10. When the water inlet valve 4 is working, the clean water at the end of the water flow channel squeezes the water stop pad 14. When water is discharged, the inner cavity of the water stop pad loses the pressure holding state, and the water stop pad 14 moves to the right under the action of water pressure. The clean water inside the water flow channel flows into the interior of the positioning sleeve 7 through the gap between the water flow channel and the water stop pad 14, and flows from the notch to the water outlet interface 13 for water discharge. When water is stopped, the inner cavity of the water stop pad is in a pressure holding state, and the water stop pad 14 abuts against the end of the water flow channel to prevent clean water from flowing out;

[0043] In order to change the pressure inside the water stop cavity, a water inlet hole is opened on the side wall of the water stop cavity, and a baffle is arranged at the water inlet hole on the switch movable plug 10. When the reset spring 9 is in the initial state, the baffle abuts against the water inlet hole;

[0045] Specifically, in this embodiment, a sealing ring 8 is provided at the connection between the water stop cover 15 and the water inlet valve 4 to ensure the sealing performance when the water stop cover 15 and the water inlet valve 4 are connected.

[0046] Example 2

[0047] See also Figure 8-11 The present embodiment is different from the embodiment 1 in that it further comprises a toilet cover 19 and a toilet ring 21; the toilet cover 19 is rotatably mounted on the toilet ring 21, the toilet ring 21 is rotatably mounted on the toilet 1, and a heating resistor wire 23 is provided in an inner ring of the toilet ring 21 for heating the surface of the toilet ring 21, thereby increasing the surface temperature of the toilet ring 21 and increasing the comfort of the toilet ring 21 when used in winter;

[0048] An annular groove 22 is provided on the inner side of the toilet cover 19, and two cleaning brushes 24 are symmetrically slidably installed on the front and rear sides of the annular groove 22. When the toilet cover 19 is closed on the toilet ring 21, the cleaning brush 24 is attached to the surface of the toilet ring 21; two screws 25 are symmetrically rotatably installed on the front and rear sides of the interior of the toilet cover 19, and the ends of the two screws 25 are connected by a belt 28 for transmission. A driving motor 27 for driving one of the screws 25 to rotate is also installed inside the toilet cover 19, thereby driving the two screws 25 to rotate in the same direction at the same time. A screw sleeve 26 is threadedly connected to the screw 25, and the screw sleeve 26 is fixedly connected to the back of the cleaning brush 24. The screw sleeve 26 is slidably installed inside the toilet cover 19. When the screw 25 drives the screw sleeve 26 to slide left and right inside the toilet cover 19, the cleaning brush 24 follows the screw sleeve 26 to slide on the annular groove 22;

[0049] Since the annular groove 22 is an arc-shaped structure, in order to ensure that the cleaning brush 24 can slide smoothly on the annular groove 22, the cleaning brush 24 is an elastic telescopic structure. After the toilet ring 21 is used, the toilet cover 19 is closed so that the cleaning brush 24 is attached to the surface of the toilet ring 21. The toilet ring 21 is cleaned by moving the cleaning brush 24 to ensure that the surface of the toilet ring 21 is clean;

[0050] A control device 20 is also provided at the connection between the toilet cover 19 and the toilet seat 21 . The control device 20 includes a temperature control button for controlling the start-up of the heating resistor 23 and a cleaning control button for controlling the operation of the driving motor 27 .

[0051] The working principle of the pneumatically controlled toilet with the water tank hidden under the toilet seat includes the following steps:

[0052] S1. Press the pneumatic button 5, the compressed gas is transmitted to the air bag 17 in the water inlet valve through the air pipe 12, the air bag 17 swells and pushes the switch movable plug 10 to move forward, leaving the sealing end, so that the inner cavity of the water stop pad loses the pressure-maintaining state;

[0053] S2. Under the water pressure at the front end of the water stop pad 14, the water stop end of the water stop pad 14 moves backward, and the clean water inside the water flow channel flows into the interior of the positioning sleeve 7 through the gap between the water flow channel and the water stop pad 14, and flows from the notch to the water outlet interface 13 for water discharge, and the surface flushing nozzle 2 sprays and flushes the toilet 1;

[0054] S3, at the same time, the drain valve 6 also drains water, and the toilet is flushed both up and down;

[0055] S4. After pressing the pneumatic button, the air pressure is released instantly, the air bag 17 is reset, and the switch movable plug 10 is reset under the action of the reset spring 9, and moves backward into the sealing end, and the water stop cavity returns to the pressure-maintaining state;

[0056] S5. At the same time, when the drain valve 6 drains the clean water inside the hidden water tank 3 to the remaining water level, the drain valve 6 is reset to seal the water, the water inlet valve allows water to enter, and the water tank is filled with water to the working water level before the water stops.

[0057] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
