The water in the external municipal pipeline is first connected to the water inlet valve, and then the water enters the water storage body to fill the water inlet pipeline, the water storage body and the water outlet pipeline. Because of the air at the top of the water storage body, the water fills part of the space and compresses the air until the external water pressure is the same as the air pressure, at which time the water stops flowing. When flushing the toilet, the water in the water storage body, the water inlet pipeline and the water outlet pipeline can be quickly released to flush the toilet at a relatively large pressure under the combined action of the pressure of the compressed air and the pressure of the external water, thereby achieving the use of external water pressure to compress air to store energy and water, high-efficiency cleaning of the toilet without using electric energy, saving energy, compact structure, small volume and providing stronger and faster cleaning effect.

[0021] The working process of the pressurized quick-flushing water-saving cleaning system of the application is as follows:

[0022] When the toilet needs to be flushed, the drain switch of the waterway switch control mechanism is pressed by hand to control the water in the first drain branch pipe and the second drain branch pipe to be discharged from the water outlet branch pipe.

[0023] Because the first switch water outlet is in communication with the first buffer cavity, the first drain branch pipe is in communication with the first switch water outlet of the water inlet valve, and the drain switch controls the water in the first buffer cavity of the water inlet valve to be discharged in sequence through the first switch water outlet, the first drain branch pipe and the water outlet branch pipe. At this time, the water pressure of the first water outlet cavity is greater than that of the first buffer cavity, and the first piston of the water inlet valve compresses the first spring and moves upward. The first piston does not block the first shell water outlet, the first shell water inlet is in communication with the water inlet pipeline, the first water outlet cavity is in communication with the first shell water inlet, and the first shell water outlet is in communication with the first water outlet, that is, the water inlet pipeline, the first shell water inlet, the first water outlet cavity, the first shell water outlet and the first water outlet form a communicating waterway, and the water is discharged in sequence from the water inlet pipeline, the first shell water inlet, the first water outlet cavity, the first shell water outlet and the first water outlet. The first water outlet is connected with the upper drain port of the toilet seat, and the water is flushed from the upper part of the toilet seat. When the drain switch controls the water in the first drain branch pipe and the second drain branch pipe to stop being discharged from the water outlet branch pipe, at this time the water pressure of the first water outlet cavity of the water inlet valve is equal to that of the first buffer cavity, and the first piston slowly descends to block the first shell water outlet under the action of the restoring force of the first spring and the resistance of the water. The first shell water outlet stops discharging water to the first water outlet, and has the function of delayed water discharge.

[0024] Since the second switch water outlet is communicated with the second buffer cavity, the second drain branch pipe is communicated with the second switch water outlet of the water outlet valve, and the water in the second buffer cavity of the water outlet valve is sequentially discharged through the second switch water outlet, the second drain branch pipe and the water outlet branch pipe under the control of the drain switch. At this time, the water pressure of the second water outlet cavity is greater than the water pressure of the second buffer cavity, the second piston of the water outlet valve compresses the second spring and moves upward. The second piston does not block the second shell water outlet, the second shell water inlet is communicated with the water outlet pipeline, the second water outlet cavity is communicated with the second shell water inlet, the second shell water outlet is communicated with the second water outlet, that is, the water outlet pipeline, the second shell water inlet, the second water outlet cavity, the second shell water outlet and the second water outlet form a communicated water path, and the water is sequentially discharged from the water outlet pipeline, the second shell water inlet, the second water outlet cavity, the second shell water outlet and the second water outlet, and the second water outlet is connected with the bottom drain port of the toilet seat, so that the toilet seat is flushed from the bottom. When the water in the first drain branch pipe and the second drain branch pipe stops being discharged from the water outlet branch pipe under the control of the drain switch, at this time, the water pressure of the second water outlet cavity of the water outlet valve is equal to the water pressure of the second buffer cavity, the second piston slowly descends and blocks the second shell water outlet under the action of the restoring force of the second spring and the resistance of the water, the second shell water outlet stops discharging water to the second water outlet, and the function of delayed water discharge is achieved.

[0086] The first housing 41 is provided with a guide column 40 for guiding the first piston 42 up and down, so as to prevent the first piston 42 from deviating and failing to seal the first housing water outlet 47 when moving up and down. There is a gap between the guide column 40 and the first piston 42 for allowing water flow, and water can flow from the first housing water inlet 46 to the first water outlet cavity 44.

[0087] A one-way valve 103 is arranged on the channel of the water inlet.

[0088] The water outlet valve 5 is arranged at the second water outlet of the water outlet pipeline 3 and controls the opening and closing of the second water outlet 8. The water outlet valve 5 comprises a second housing 51, a second piston 52 and a second spring 53, the second piston 52 and the second spring 53 are arranged in the second housing 51, one end of the second spring 53 abuts against the upper part of the second piston 52, the other end of the second spring 53 abuts against the top of the second housing 51, the second piston 52 separates the second housing 51 into two cavities, namely a second water outlet cavity 54 and a second buffer cavity 55, the second water outlet cavity 54 and the second buffer cavity 55 are communicated through a second small hole 59, the second housing 51 is provided with a second housing water inlet 56, a second housing water outlet 57 and a second switch water outlet 58, the second housing water inlet 56 is communicated with the water outlet pipeline 3, the second water outlet cavity 54 is communicated with the second housing water inlet 56, the second housing water outlet 57 is communicated with the second water outlet 8, the second switch water outlet 58 is communicated with the second buffer cavity 55, and the second piston 52 blocks the second housing water outlet 57 when the second housing water outlet 57 is not watered.

[0091] Compared with the prior art, the pressurized quick flushing water-saving cleaning system utilizes the water compression air in the closed space of the water storage body and stores the water pressure energy in the municipal pipeline. The water inlet pipeline communicated with the water storage body is used for controlling water inlet and upper flushing water of the closestool, and the water outlet pipeline communicated with the water storage body is used for controlling lower flushing water of the closestool. The water of the external municipal pipeline is first connected to the water inlet valve, and then the water enters the water storage body, fills the water inlet pipeline, the water storage body and the water outlet pipeline, and because of the existence of air at the top of the water storage body, the water fills part of the space and compresses the air until the external water pressure and the air pressure are the same, at which time the water stops flowing. When flushing the closestool, due to the combined action of the pressure of the compressed air and the pressure of the external water, the water in the water storage body, the water inlet pipeline and the water outlet pipeline can be quickly released at a relatively large pressure to flush the closestool, so that the external water pressure compression air energy is absorbed and stored, the closestool is efficiently cleaned without using electric energy, energy is saved, the structure is compact, the volume is small, and stronger and faster cleaning effect can be provided.

[0092] The working process of the pressurized quick-flushing water-saving cleaning system is as follows:

[0093] When the toilet needs to be flushed, the drain switch of the waterway switch control mechanism is pressed by hand, and the drain switch controls the water in the first drain branch pipe and the second drain branch pipe to be discharged from the water outlet branch pipe.

[0094] Since the first switch water outlet is in communication with the first buffer cavity, the first drain branch pipe is in communication with the first switch water outlet of the water inlet valve, and the drain switch controls the water in the first buffer cavity of the water inlet valve to be discharged in sequence through the first switch water outlet, the first drain branch pipe and the water outlet branch pipe; at this time, the water pressure of the first water outlet cavity is greater than that of the first buffer cavity, and the first piston of the water inlet valve compresses the first spring and moves upward. The first piston does not block the first shell water outlet, the first shell water inlet is in communication with the water inlet pipeline, the first water outlet cavity is in communication with the first shell water inlet, the first shell water outlet is in communication with the first water outlet, that is, the water inlet pipeline, the first shell water inlet, the first water outlet cavity, the first shell water outlet and the first water outlet form a communication waterway, and the water is discharged in sequence from the water inlet pipeline, the first shell water inlet, the first water outlet cavity, the first shell water outlet and the first water outlet, and the first water outlet is connected with the upper drain port of the toilet seat, so as to flush the upper part of the toilet seat. When the drain switch controls the water in the first drain branch pipe and the second drain branch pipe to stop being discharged from the water outlet branch pipe, at this time, the water pressure of the first water outlet cavity of the water inlet valve is equal to that of the first buffer cavity, and the first piston slowly descends to block the first shell water outlet under the action of the restoring force of the first spring and the resistance of the water, the first shell water outlet stops discharging water to the first water outlet, and has the function of delayed water discharge.

[0095] When the water in the second water outlet cavity is higher than the water in the second buffer cavity, the second piston of the water valve compresses the second spring and moves upward. The second piston does not block the second shell outlet, the second shell inlet is communicated with the water outlet pipeline, the second water outlet cavity is communicated with the second shell inlet, the second shell outlet is communicated with the second water outlet, that is, the water outlet pipeline, the second shell inlet, the second water outlet cavity, the second shell outlet and the second water outlet form a communicated water path, and the water is discharged from the water outlet pipeline, the second shell inlet, the second water outlet cavity, the second shell outlet and the second water outlet in turn, and the second water outlet is connected with the bottom drain of the toilet seat, so that the water is flushed from the bottom of the toilet seat. When the water in the first water outlet cavity is equal to the water in the second buffer cavity, the second piston slowly drops under the action of the restoring force of the second spring and the resistance of the water, and blocks the second shell outlet, so that the second shell outlet stops discharging water to the second water outlet, thereby achieving the function of delayed water discharge.
