In the embodiment of the present utility model, referring to fig. 1 and 2, a flushing valve set is provided, where the flushing valve set includes a first switching component 100, a water pump 200, a pump nozzle path 10, a first valve set 300 and a flushing pipeline 20, the water pump 200 provides flowing power for water flow in an electrified state, the water flow can reach a bottom nozzle of a toilet bowl through the pump nozzle path 10, perform jet flushing or perform water seal water replenishing, and reach a skirt of the toilet bowl through the flushing pipeline 20 to perform flushing, and the first switching component 100 is used for switching on and off states of different valve portions in the first valve set 300 so that water flows through the different valve portions into corresponding pipelines to perform flushing.

Specifically, the first switching assembly 100 includes a housing 110, a water storage bag 120 and a pushing member 130, wherein a cavity is formed in the housing 110, the water storage bag 120 is accommodated in the housing 110, the housing 110 has a water inlet 111 and a water outlet 112 which are communicated with the cavity in the housing 110, and external water can enter the housing 110 through the water inlet 111 and be discharged through the water outlet 112; the water storage bag 120 can stretch and retract along with the flow change of the water flow entering the shell 110, and changes the opening degree of the water outlet 112, namely, when the water flow does not enter the shell 110, the water storage bag 120 is in a free stretching state and seals the water outlet 112, when the water flow enters the shell 110 in a larger amount in unit time, the compression degree of the water storage bag 120 is higher, the opening degree of the water outlet 112 is larger, and when the water flow enters the shell 110 in a smaller amount in the unit time, the compression degree of the water storage bag 120 is smaller, and the opening degree of the water outlet 112 is smaller. It will be appreciated that since the pushing member 130 is connected to the water storage bladder 120, the range of motion of the pushing member 130 is greater when the compression of the water storage bladder 120 is higher, and the range of motion of the pushing member 130 is smaller when the compression of the water storage bladder 120 is lower.

The first valve block 300 includes a first valve body 310 and a first swing link 320, the first valve body 310 having a brush valve portion 311, the first swing link 320 being rotatably connected to the first valve body 310 and being swung by being pushed by the pushing member 130 to open or close the brush valve portion 311. The flushing valve group further comprises a first water inlet pipeline 30 and a second water inlet pipeline 40, one end of the first water inlet pipeline 30 is communicated with the water inlet 111, the other end of the first water inlet pipeline 30 is connected with the water pump 200, and the water pump 200 can extract water in the water tank and supply water to the inside of the shell 110 through the first water inlet pipeline 30. The second water inlet pipe 40 is used for supplying tap water, and is connected with the first valve body 310. One end of the pump spray pipeline 10 is communicated with the water outlet 112, the other end of the pump spray pipeline extends to a bottom spout of the toilet, water flow can flow to the bottom spout through the pump spray pipeline 10 for water seal water supplementing or jet flushing, one end of the washing pipeline 20 is communicated with the washing valve part 311, the other end of the washing pipeline extends to the skirt of the toilet, and water flow can flow to the toilet skirt through the washing pipeline 20 for washing and flushing.

In this embodiment, the flushing valve set has a first working mode and a second working mode set after a preset time of working in the first working mode. Specifically, in the power-on state, when the flushing valve group is in the first working mode, the water pump 200 drives water to enter the shell 110 through the water inlet 111, the water storage bag 120 is compressed, the water outlet 112 is opened, the opening degree of the water outlet 112 is H ₁, the pushing piece 130 pushes the first swing rod 320 to swing along with the compression of the water storage bag 120, the first swing rod 320 opens the flushing valve part 311, at the moment, the flushing pipeline 20 is in a conducting state, tap water enters the flushing pipeline 20 through the second water inlet pipeline 40, and the flushing toilet is flushed; meanwhile, water entering the interior of the housing 110 flows into the pump nozzle circuit 10 through the water outlet 112, and the water is used for water sealing and supplementing the toilet bowl at the first flow Q ₁. After the flushing valve group works in the first working mode for a preset time, the flushing valve group enters the second working mode, when the flushing valve group is in the second working mode, the water storage bag 120 is continuously compressed, the opening degree of the water outlet 112 is switched to H ₂, the pushing piece 130 continuously pushes the first swing rod 320, the flushing valve part 311 is always in a conducting state, and tap water is used for flushing and flushing the toilet bowl through the flushing pipeline 20; at the same time, the water flow is used for spraying and flushing the closestool at a second flow Q ₂. In the above, H ₂＞H₁,Q₂＞Q₁.

Therefore, the opening of the water outlet 112 of the flushing valve set in the first working mode and the flow of water flow in the pump spray pipeline 10 are smaller, the opening of the water outlet 112 in the second working mode and the flow of water flow in the pump spray pipeline 10 are larger, the first working mode and the second working mode are sequentially carried out, the water seal water supplementing and the washing and flushing are carried out on the toilet in the first working mode, dirt on the skirt of the toilet can be cleaned, the dirt at the bottom nozzle of the toilet is soaked, the subsequent cleaning is more thorough, and the water flow in the pump spray pipeline 10 is smaller in the process, so that the water saving is facilitated; when the toilet is sprayed and flushed in the second working mode, the opening of the water outlet 112 is larger, so that instant large flow which is beneficial to siphoning can be generated, the spraying and flushing of the toilet are more thorough, the flushing pipeline 20 synchronously uses tap water for flushing, and the flushing effect of the toilet can be improved.

It should be noted that, the flushing valve group can flush by utilizing water in the water tank and tap water in the first working mode and the second working mode, so that the defect of insufficient flushing caused by water supply of a single water source is overcome.

In one embodiment, the operating power of water pump 200 in the first mode of operation is set to be less than the operating power of water pump 200 in the second mode of operation such that the flow rate of water delivered by first water inlet line 30 to housing 110 in the first mode of operation is less than the flow rate of water delivered to housing 110 in the second mode of operation. Specifically, the water pump 200 is set to operate in a half-power state when the flushing valve group is in the first working mode, and the water pump 200 is set to operate in a full-power state when the flushing valve group is in the second working mode, so that compared with the situation that the water pump 200 directly operates in the full-power state, the pneumatic instantaneous peak current of the water pump 200 can be eliminated, and the protection circuit is realized. The water pump 200 is fixed at the bottom of the water tank, can be completely covered by water, has the effects of cooling and noise reduction, and can prevent empty pumping.

The water storage bladder 120 is provided as a member capable of being compressed to be elastically contracted and having an elastic restoring force after the pressure is removed, for example, as a bellows type. In an embodiment, the pushing member 130 moves in a moving manner and contacts with the first swing rod 320, the pushing member 130 pushes the first swing rod 320 to swing based on a rotational connection position with the first valve body 310 during the moving process, and the shrinkage of the water storage bag 120 can be directly converted into the movement of the pushing member 130, so that the transmission efficiency is high. Further, the water storage bag 120 is hollow, so as to be more beneficial to deformation and shrinkage of the water storage bag 120, so that the change of water flow entering the shell 110 can effectively react to the movement stroke of the pushing member 130; part of the pushing member 130 is accommodated in the water storage bag 120, one end of the pushing member 130 is connected to the bottom of the water storage bag 120, the other end of the pushing member 130 penetrates out of the shell 110 and can push the first swing rod 320 to swing, when the water storage bag 120 is contracted, the pushing member 130 moves upwards and pushes one end of the first swing rod 320 to lift upwards, and when the water storage bag 120 stretches, the pushing member 130 moves downwards and removes the pushing force on the first swing rod 320.

In order to make the movement of the pushing member 130 smoother, in an embodiment, a channel arranged along the movement direction of the pushing member 130 is arranged at the top of the housing 110, the channel is communicated with a cavity in the housing 110, the pushing member 130 is arranged in the channel in a penetrating manner, and the first swing rod 320 is positioned above the pushing member 130; when the pushing member 130 moves to the top to contact with the first swing link 320 and continuously moves upwards, the first swing link 320 is pushed to swing, and the channel guides the movement of the pushing member 130 in the process, so that the pushing member 130 always moves vertically, and the pushing member 130 is prevented from deflecting and separating from the first swing link 320.

Further, the water inlet 111 is disposed at the bottom of the housing 110, and the water flowing into the housing 110 from the water inlet 111 is disposed at the lower portion of the water storage bag 120, so that the water storage bag 120 is contracted upwards by the pressure and buoyancy of the water flow, and the water storage bag 120 is contracted more rapidly. In addition, the first switching assembly 100 further includes a baffle 140, the baffle 140 is connected to the bottom of the water storage bladder 120, and the side of the baffle 140 contacts with the side wall of the inside of the housing 110; on the one hand, the bottom surface of the baffle 140 is relatively flat, the contact area with water flow is large, the baffle 140 is guided by the inner wall of the shell 110 when moving, so that the movement of the pushing piece 130 is more stable, on the other hand, a sealing cavity is formed between the baffle 140 and the bottom wall inside the shell 110, and the water flow pressure can be effectively transmitted to the water storage bag 120, so that the water storage bag 120 is quickly contracted. The top of the water storage bladder 120 is opened to allow the pushing member 130 to protrude, the top edge of the water storage bladder 120 is connected to the housing 110, and the inner cavity of the water storage bladder 120 is also in a sealed state.

In the present embodiment, the opening degree of the water outlet 112 refers to a distance between the water outlet 112 and the area communicating with the interior of the housing 110 in the moving direction of the pushing member 130.

It will be appreciated that a passage communicating with the second water inlet line 40 should be provided in the first valve body 310, and when the brush valve portion 311 is opened, the passage communicates with the brush line 20 through the brush valve portion 311, and tap water enters the brush line 20 through the brush valve portion 311.

Specifically, the pressure relief hole is located between the rotational connection position of the first swing link 320 and the first valve body 310 and the contact position of the first swing link 320 and the pushing member 130, and the pressure relief hole is located below the first swing link 320, when the pushing member 130 pushes the first swing link 320 upward, the first swing link 320 swings upward and is far away from the pressure relief hole, so that the scrubbing valve portion 311 is opened.

In addition, a rubber plug matched with the pressure relief hole is arranged on the first swing rod 320, so that the plugging effect of the first swing rod 320 on the pressure relief hole is guaranteed. In addition, after the first swing rod 320 releases the blocking of the pressure relief hole, the pressure relief hole is directly communicated with the external atmosphere, so that a large pressure difference can be generated, and large-flow water outlet is realized.
