A water circuit switch control mechanism for a pressurized fast flushing water-saving cleaning system

Abstract

The present invention provides a water circuit switch control mechanism of a pressurized fast flushing water-saving cleaning system, wherein the water inlet valve is arranged at the first water outlet of the water inlet pipeline and controls the switch of the first water outlet; the water outlet valve is arranged at the second water outlet of the water outlet pipeline and controls the switch of the second water outlet; and the drainage switch group controls the water inlet valve and the water outlet valve at the same time. Water from an external municipal pipeline is first connected to the water inlet valve, and then the water enters the water storage body. Because there is air at the top of the water storage body, the water will fill part of the space and compress the air until the external water pressure is the same as the air pressure, at which time the water stops flowing. Due to the combined effect of the pressure of the compressed air and the pressure of the external water pressure, under the control of the water circuit switch control mechanism, the water in the water storage body, the water in the water inlet pipeline and the water outlet pipeline can be quickly released at a relatively large pressure to flush the toilet, so as to achieve the purpose of utilizing the external water pressure to compress the air to absorb energy and store water, and efficiently clean the toilet without using electric energy, and can provide a stronger and faster cleaning effect.

[0071] Compared with the prior art, the water circuit switch control mechanism of the pressurized fast flushing water-saving cleaning system of the present invention cooperates with the water storage body to utilize external water pressure to compress the air to absorb energy and store water, and efficiently cleans the toilet without using electricity. It saves energy, has a compact structure, a small size, and can provide stronger and faster cleaning effects.

[0072] The water inlet pipe connected to the water storage body is used to control the water inlet and the upward flushing of the toilet, and the water outlet pipe connected to the water storage body is used to control the downward flushing of the toilet. The water from the external municipal pipeline is first connected to the water inlet valve, and then the water enters the water storage body, filling the water inlet pipe, the water storage body and the water outlet pipe. Because there is air at the top of the water storage body, the water will fill part of the space and compress 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, due to the combined effect of the pressure of the compressed air and the pressure of the external water pressure, the water in the water storage body, the water in the water inlet pipe and the water outlet pipe can be quickly released at a relatively high pressure to flush the toilet, so as to achieve the purpose of using the external water pressure to compress the air to absorb energy and store water, and efficiently clean the toilet without using electricity. It saves energy, has a compact structure, a small size, and can provide a stronger and faster cleaning effect.

[0073] The working process of the pressurized fast flushing water-saving cleaning system of the present invention is as follows:

[0074] When the toilet needs to be flushed, the drainage switch of the water circuit switch control mechanism is pressed by hand, and the drainage switch controls the water in the first drainage branch pipe and the second drainage branch pipe to be discharged from the water outlet branch pipe.

[0075] Since the first switch water outlet is connected with the first buffer cavity, the first drainage branch is connected with the first switch water outlet of the water inlet valve, and the drainage switch controls the water in the first buffer cavity of the water inlet valve to be discharged through the first switch water outlet, the first drainage branch, and the water outlet branch in sequence; at this time, the water pressure of the first water outlet cavity is greater than the water pressure 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 connected with the water inlet pipeline, the first water outlet cavity is connected with the first shell water inlet, and the first shell water outlet is connected 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 connected waterway, and water is discharged 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 in sequence, and the first water outlet is connected with the upper drainage port of the toilet seat to flush water from the upper part of the toilet seat. When the drain switch controls the water of the first drain branch and the second drain branch to stop being discharged from the water outlet branch, at this time, the water pressure of the first water outlet chamber of the water inlet valve is equal to the water pressure of the first buffer chamber, and the first piston slowly descends to block the first shell water outlet under the action of the first spring restoring force and the water resistance, and the first shell water outlet stops draining water to the first water outlet, which has the function of delayed drainage.

[0076] Since the second switch water outlet is connected to the second buffer cavity, the second drainage branch pipe is connected to the second switch water outlet of the water outlet valve, and the water in the second buffer cavity of the water outlet valve controlled by the drainage switch is discharged through the second switch water outlet, the second drainage branch pipe, and the water outlet branch pipe in sequence. At this time, the water pressure of the second water outlet cavity is greater than the water pressure of the second buffer cavity, and 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 connected to the water outlet pipeline, the second water outlet cavity is connected to the second shell water inlet, and the second shell water outlet is connected to 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 connected waterway, and water is 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 in sequence, and the second water outlet is connected to the bottom drain of the toilet seat, and flushes from the bottom of the toilet seat. When the drain switch controls the water of 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 second water outlet chamber of the water outlet valve is equal to the water pressure of the second buffer chamber, and the second piston slowly descends to block the second shell water outlet under the action of the second spring restoring force and the water resistance, and the second shell water outlet stops draining water to the second water outlet, which has the function of delayed drainage.
