[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0022] Refer to the attached Figure 1 to the attached Figure 6 , a toilet flushing system, comprising a toilet seat 1 and a water inlet and outlet system 2. The toilet seat 1 includes a seat body 11 and a main body 12 located at the rear side of the seat body 11. The seat body 11 has a water inlet 111 and a sewage chamber 112. The water inlet 111 is located on the rear side wall of the sewage chamber 112. A sewage outlet 112a is provided at the bottom of the sewage chamber 112. The water inlet 111 is communicated with a water supply place to flush the dirt in the seat body 11 into the sewage outlet 112a. The main body 12 is used to arrange the flushing system of the toilet. The main body 12 includes a first accommodation space 121 and a second accommodation space 122. The second accommodation space 122 is arranged at the bottom of the first accommodation space 121, that is, the second accommodation space 122 is arranged in the direction close to the ground. The upper cover of the first accommodation space 121 is openable, and the second accommodation space 122 is closed. The first accommodation space 121 and the second accommodation space 122 are separated by a partition 123. Preferably, the main body 12, the partition 123 and the seat body 11 are integrally formed. For example, the toilet seat is a ceramic toilet, and the main body 12, the partition 123 and the ceramic toilet are integrally formed in the same process. More preferably, the first accommodation space 121 is provided with a water outlet hole on the side or bottom (the opening at the bottom is not communicated with the second accommodation space) to prevent the leakage caused by the aging of the parts of the water inlet and outlet system from accumulating in the main body.

[0023] Further, the partition 123 has a through hole a, and a boss b is protrudingly provided on the outer periphery of the through hole a. The water inlet and outlet system 2 includes a water inlet and outlet channel 21, a water passing channel 22, and a flushing valve 23. Among them, at least a part of the water inlet and outlet channel 21 extends into the water passing channel 22. The flushing valve 23 is arranged in the first accommodation space 121. The upper end of the water passing channel 22 passes through the through hole a of the partition and a part of the boss b from the second accommodation space 122 and extends into the first accommodation space 121. Among them, a fixing member 31 is connected to the outer periphery of the water passing channel 22. The fixing member 31 is placed above the boss b. The fixing member 31 can be screwed and fixed to the outer periphery of the water passing channel 22 to cooperate with the boss to fix the water passing channel. Preferably, a sealing member 4 is arranged between the water passing channel 22 and the boss b. A plurality of convex points 41 are arranged on the outer periphery of the sealing member 4, and a plurality of grooves are formed on the inner side of the boss b. The convex points 41 and the grooves cooperate with each other to ensure the sealing of the through hole. Preferably, the sealing member 4 is in a "[-]" shape, and the convex points are arranged in the middle of the "[-]" shape to further ensure the sealing. The water inlet and outlet channel 21 includes a main body part 211 and an extension part 212. The radius of the extension part 212 is smaller than that of the main body part 211. The inside of the main body part 211 is divided into a water inlet channel 211a and a water outlet channel 211b. The water inlet channel 211a and the extension part 212 are communicated with each other, and the water inlet channel 211a and the water outlet channel 211b are respectively communicated with the external water supply and the water inlet of the flushing valve. Among them, the extension part 212 extends into the water passing channel 22, and at the same time, the two are connected and fixed by a locking member 5. The locking member can be connected and fixed by screwing, buckling or welding. Further, in order to maintain the sealing, a sealing gasket d can also be arranged between the outer periphery of the main body part 211 of the water inlet and outlet channel and the inner side of the water passing channel 22. In this way, the water passing channel 22 is communicated with both the water inlet channel 211a and the water outlet channel 211b. The water inlet and outlet system 2 directly uses a water inlet and outlet channel and a water passing channel to realize the entry and discharge of water flow, ensure the sealing of the second accommodation space, and can better store the water pressure energy.

[0024] In addition, the flushing valve 23 includes a valve body 231, a valve stem 232 and a button 233. The valve body 231 includes a water inlet 231a and a water outlet 231b. The water inlet 231a is communicated with the water outlet passage 211b, and the water outlet 231b is communicated with the water inlet 111. The valve stem 232 extends radially into the valve body 231. An elastic member 234 is arranged between the valve stem 232 and the button 233. The valve stem 232 moves up and down under the cooperation of the button and the elastic member to cooperate with the valve seat to start the water flow in the water outlet passage to flow into the sewage chamber through the water outlet. Further, in order to ensure that the pressure in the sealed second accommodation space can be kept stable, a connecting passage 231c is also arranged on the valve body 231 of the flushing valve. A water pipe 32 is also arranged on the main body portion 211 of the water inlet and outlet passage 21. The water pipe 32 and the connecting passage 231c are communicated with each other to form a third accommodation space 33. Preferably, the connecting passage 231c extends into the water pipe 32 and is sealed and fixed between them by a sealing ring. A spring member 331 and a valve rod member 332 are arranged in the third accommodation space 33. The valve rod member 332 includes a head 332a and a connecting rod 332b. A sealing ring is arranged on the outer periphery of the head 332a. The connecting rod 332b is arranged between the head and the connecting passage. A seat body is arranged at the connecting passage 231c. There is a gap between the seat body and the water pipe. One end of the spring member 331 abuts against the gap, and the other end abuts against the head 332a. In this way, when the external water supply enters the second accommodation space 122 from the water inlet passage 211a, since the second accommodation space 122 is sealed, the air inside is squeezed, the pressure continuously increases, and the water pressure energy is stored. Then, the valve rod member 332 is pushed to compress the spring member 331, providing a certain pressure buffer, so as to stabilize the internal pressure within a certain range and ensure the stability of the entire system operation. After that, when the pressurized water flow is released, the valve rod member resets under the elastic force of the spring member and works in a cycle. Thus, the toilet flushing system of the present invention places the second accommodation space at the bottom of the toilet seat. By cooperating with the water inlet and outlet system, the second accommodation space can store water pressure energy while storing water, ensuring that the water can generate a greater thrust when released, having a stronger sewage discharge capacity, being able to clean quickly and save water, and transferring the traditional upper-mounted water tank to the bottom of the toilet seat, which can save space, make the volume of the toilet smaller, and is very beneficial for transportation.
