Example one

Referring to fig. 1 to 18, a pressure flushing apparatus includes a pressure relief control valve 10 and at least two flushing assemblies. Each flushing assembly is provided with a pressure water tank 60, a water inlet valve 30, a water discharge valve 50 and the like, namely, at least two flushing assemblies are mutually independent assemblies, the number of the flushing assemblies can be two or three or more, and the flushing assemblies can be set according to requirements, and two flushing assemblies are preferred.

Wherein the pressure water tank 60 is a closed water tank, which is provided with a first water inlet 61 and a first water outlet 62, and the first water inlet 61 can be located at the top of the water tank or other suitable positions. The first outlet 62 may also be disposed at the top of the tank or other suitable location, and may be configured as a tube extending toward the inside of the pressurized water tank 60 and near the bottom surface to facilitate drainage.

Referring to fig. 6, the feed valve 30 is connected to a first feed port 61 for feeding water into the pressurized water tank 60. In the present invention, the inlet valve 30 may be an inlet valve 30 having a pressure relief function, that is, when the pressure in the pressurized water tank 60 is too high, the pressure can be relieved. Specifically, the inlet valve 30 includes a second valve body 31, a pressure relief assembly 40, and the like. The second valve body 31 is provided with a third water inlet 32, a third water outlet 33, a third pressure relief port 34, and the like. The third water inlet 32 is adapted to be connected to a water inlet conduit 35. For multiple flush assemblies, the third inlet port 32 of its inlet valve 30 may communicate with the same inlet conduit 35.

The third water inlet 32 is further provided with a check valve 36, and when the pressure water tank 60 is filled with water, the water flow cannot flow back to the water inlet pipe 35 from the third water inlet 32 due to the check valve 36, so that the water backflow is prevented. The check valve 36 can be realized by a common structure, and in the present invention, a rubber ball can be used, and a limiting groove is arranged in the third water inlet 32, and the rubber ball is positioned in the limiting groove and can open or cut off the third water inlet 32.

The third water inlet 32 is communicated with the third water outlet 33 and the third pressure relief opening 34, that is, water can flow out from the third water outlet 33 or the third pressure relief opening 34 through the third water inlet 32. The third water outlet 33 is communicated with the first water inlet 61, that is, the water flows to the pressure water tank 60 through the third water outlet 33. The pressure relief assembly 40 is located in the second valve body 31 to close the third pressure relief opening 34, at this time, water flows out from the third water outlet 33, or the third pressure relief opening 34 is opened when the pressure of the pressure water tank 60 exceeds a second preset value, at this time, water flows out from the third pressure relief opening 34 to realize pressure relief, so that the pressure in the pressure water tank 60 is prevented from being too high.

In this embodiment, a pressure maintaining valve 37 is further included, and the pressure maintaining valve 37 is installed at the water inlet end of the water inlet valve 30. Multiple flushing assemblies may share a single pressure maintaining valve 37, i.e., the pressure maintaining valve 37 may be mounted on the inlet conduit 35. When the water pressure in the pressurized water tank 60 is higher than the set value of the pressure maintaining valve 37, the pressure maintaining valve 37 is closed, and the water in the water inlet pipe 35 cannot flow into the water inlet valve 30. The pressure maintaining valve 37 may be implemented using a conventional pressure maintaining valve structure, which is not limited herein.

Specifically, the pressure relief assembly 40 includes a fixed element 41, a movable element 42 and a second elastic element 43, the fixed element 41 is fixed in the second valve body 31 and is provided with a communication cavity 44, and the communication between the third water inlet 32 and the third water outlet 33 and the third pressure relief opening 34 is realized through the communication cavity 44; the movable member 42 is movably disposed between the communication cavity 44 and the third pressure relief opening 34, and a sealing gasket may be used, and the movable member 42 may be located at an inner end of the third pressure relief opening 34. The second elastic member 43 is stretched between the movable member 42 and the corresponding end of the second valve body 31 so that the movable member 42 blocks the inner end of the third relief port 34, thereby closing the communication between the communication chamber 44 and the third relief port 34.

The pressure relief assembly 40 is arranged, if the pressure maintaining valve 37 fails, the water inlet valve 30 continuously feeds water, air in the pressure water tank 60 is compressed, when the pressure in the pressure water tank 60 continuously rises to a second preset value, the pressure in the pressure water tank 60 overcomes the elastic force of the second elastic element 43, the movable element 42 is driven to move to open the communication between the communication cavity 44 and the third pressure relief opening 34, and then the water in the pressure water tank 60 flows out from the third pressure relief opening 34, so that pressure relief is realized.

Further, the inner diameter of the third water outlet 33 is set to gradually decrease along the water outlet direction, and it may be set as a jet port, that is, the inner diameter of the third water outlet 33 gradually decreases along the water inlet direction, so that the flow rate of the water at the time of water outlet from the third water outlet 33 can be increased, and a negative pressure is generated around the water outlet end. The second valve body 31 is further provided with a suction channel 38 and a suction cap 39, one end of the suction channel 38 is located at the periphery of the third water outlet 33, the suction cap 39 is fixedly sleeved at the other end of the suction channel 38 and is provided with a gap or a hole, and the suction channel 38 is communicated with the outside through the gap or the hole. The suction cap 39 may be made of rubber.

In addition, the first water inlet 61 of the pressure water tank 60 can also be configured to be matched with the third water outlet 33, i.e. the inner diameter of the first water inlet 61 is gradually reduced along the water inlet direction. When water is discharged from the third water outlet 33, external air is sucked through the suction passage 38 and the suction cap 39 due to negative pressure generated by the jet flow, and the air enters the pressure tank 60 together with the water flow.

In practical applications, the inlet valve 30 may also adopt other inlet valve 30 structures without pressure relief function according to the requirement.

The third elastic member 53 is stretched between the diaphragm 52 and the inner wall of the second chamber 55, and drives the diaphragm 52 to close the communication between the fourth water inlet 56 and the fourth water outlet 57, so as to close the water discharge. When the first pressure relief opening 58 is not relieved, when the fourth water inlet 56 is filled with water, water flows into the second cavity 55 through the overflowing hole 52a until the second cavity 55 is filled with water, at this time, the water pressure on the two sides of the diaphragm 52 is the same, and the third elastic piece 53 drives the diaphragm 52 to block the fourth water outlet 57. When the first pressure relief port 58 is opened for pressure relief, water in the second chamber 55 flows out through the first pressure relief port 58, the pressure in the second chamber 55 drops sharply, the water pressure in the first chamber 54 jacks up the diaphragm 52, the fourth water outlet 57 is opened, and water flow is discharged from the fourth water outlet 57.

The water discharge valve 50 of the present invention uses the pressure difference between the first chamber 54 and the second chamber 55 to drive the diaphragm 52 to move so as to open or close the water discharge, and has a simple and reliable structure.

In this embodiment, referring to fig. 19 to 21, a water diversion box 70 is further included, the water diversion box 70 is provided with at least one water inlet 71, at least two water outlets 72 and a water mixing cavity, and the water mixing cavity is communicated with the water inlet 71 and the water outlets 72; the water outlet end of the drain valve 50 is communicated with the water inlet hole 71. The number of the water outlet holes 71 can correspond to the number of the flushing assemblies, and the number of the water inlet holes 72 can be set to be one, two or more according to requirements.

The water diversion box 70 is used for mixing water discharged from the flushing assembly and then sending out the mixed water through the water outlet hole 72. Wherein, the inner diameters of at least two water outlet holes 72 of the water distribution box 70 are set according to a preset proportion value, namely, the water flow with different flow is output by setting different inner diameters of the water outlet holes 72.

In the present invention, the relationship between the set value of the pressure maintaining valve 37 and the first preset value and the second preset value of the pressure water tank 60 is sequentially increased, for example, the set value (i.e. the pressure relief value) of the pressure maintaining valve 37 is 0.16Mpa, the first preset value of the pressure water tank 60 is 0.25Mpa, and the second preset value is 0.35Mpa, so that when the internal pressure of the pressure water tank 60 reaches 0.16Mpa, the pressure maintaining valve 37 is closed to stop water inflow. When the pressure stabilizing valve 37 fails, if the internal pressure of the pressure water tank 60 reaches 0.25Mpa, the water inlet valve 30 is opened to release the pressure. When the pressure relief function of the water inlet valve 30 fails, the pressure relief control valve 10 is opened to relieve pressure when the internal pressure of the pressure water tank 60 reaches 0.35 Mpa.

At this time, the drain valve 50 and the pressure relief control valve 10 are in a closed state, that is, the fourth water inlet 56 of the drain valve 50 is communicated with the inside of the pressure tank 60, the diaphragm 52 blocks the fourth water outlet 57, the movable sleeve 22 of the pressure relief control valve 10 blocks the second pressure relief opening 17, and the water in the pressure tank 60 can fill the second cavity 55 of the drain valve 50 and the second pressure cavity 16 of the pressure relief control valve 10.

When the water discharge is started, the button 27 on the control rod 21 is pressed downwards, the two rod bodies 26 move downwards to push the movable sleeve 22, the movable sleeve 22 moves downwards to open the second pressure relief port 17 under the action of the first elastic piece 23, water in the second pressure cavity 16 enters the first pressure cavity 15, the pressure of the second cavity 55 of the water discharge valves 50 of the two water discharge assemblies is relieved simultaneously, the water discharge valves 50 start to discharge water simultaneously, water in the pressure water tank 60 is discharged into the water distribution box 70 through the first water outlet 62, the fourth water inlet 56 and the fourth water outlet 57, flows out of the two water outlet holes 72 according to the proportion and enters the first washing flow channel and the second washing flow channel respectively to wash the body.

In the present invention, the pressure water tanks 60 of the plurality of water outlet assemblies are independent of each other, and the shape and size of the pressure water tank 60 can be set according to the need, for example, it is cylindrical, conical or square, etc. to facilitate installation at a suitable position in the toilet.

Example two

A pressure type flushing device and a toilet bowl have the same main structure as the first embodiment, namely, the structure of a pressure relief control valve 10 and a flushing assembly is the same, and the difference is that: the water distribution box 70 is not arranged, the fourth water outlet 57 of the water discharge valve 50 of one flushing component is communicated with the first flushing flow passage through a pipeline, and the fourth water outlet 57 of the water discharge valve 50 of the other flushing component is communicated with the second flushing flow passage through a pipeline.

In this embodiment, the first flushing flow passage may be a main flushing flow passage, and the second flushing flow passage may be a wash ring flow passage, so that the volume of the pressure water tank 60 connected with the first flushing flow passage may be larger than that of the pressure water tank 60 connected with the second flushing flow passage, so as to meet the requirements of different flushing water amounts.
