Detailed Description

The technical scheme and beneficial effects of the present utility model will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 3, a toilet flushing structure includes a tank 1, a water pump 2, a reversing valve 3, a three-way valve 4, a flushing water path L1 and a flushing assisting water path L2.

The water tank 1 has a water inlet pipe 11 and a water outlet pipe 12, wherein the water inlet pipe 11 is connected with a tap water pipe. The water outlet pipe 12 is connected with the water pump 2, and then is connected with the first water outlet channel 31 and the second water outlet channel 32 after passing through the reversing valve 3, and a water inlet channel 30 is formed between the water pump 2 and the reversing valve 3. The first water outlet channel 31 is connected with the washing water channel L1 after passing through the three-way valve 4, and the free end of the second water outlet channel 32 is connected with the bottom water outlet 321 to form a water assisting channel L2. Normally, the valve of the reversing valve 3 to the first outlet channel is normally closed, and only opens when the tap water pressure is greater than 0.12 MPA.

The three-way valve 4 has a first water inlet 41, a second water inlet 42 and a water outlet 43. The first water inlet 41 is connected with a tap water pipe, the second water inlet 42 is connected with the first water outlet channel 31, and the water outlet 43 is connected with the washing water channel L1.

Further, a pressure sensor and an electromagnetic pilot valve 5 are arranged between the first water inlet 41 and the tap water pipe.

Specifically, referring to fig. 7 to 10, the electromagnetic pilot valve 5 includes a valve seat 50 and an electromagnetic valve 51. The valve seat 50 has a water inlet end 501 and a water outlet end 502, a diaphragm cavity 503 is provided between the valve seat 50 and the solenoid valve 51, a spring 52, an end cover 53 and a diaphragm 54 are sequentially provided in the diaphragm cavity 503, and the diaphragm cavity is provided on a port of the water inlet end 501 of the valve seat 50. A pressure relief hole 511 and an overflow hole 512 are arranged in the electromagnetic valve 51, wherein a suspension iron 55 and a spring 56 are arranged above the pressure relief hole 511, and the overflow hole 512 is communicated with the diaphragm cavity 503. The water inlet end 501 of the valve seat 50 is provided with a water passing small hole 504 on the end wall, and the water passing small hole 504 is communicated with the pressure relief hole 511. The water inlet end 501 is connected with a tap water pipe, and the water outlet end 502 is connected with the first water inlet 41 of the three-way valve 4.

The three-way valve 4 is also provided with an anti-siphon component 6. The anti-siphon assembly 6 comprises a piston 61, a spring 62 and a decorative cover 63, wherein one end of the piston 61 is provided with a claw 611, and the other end is provided with a sealing piece 612. The wall of the three-way valve 4 is provided with an upward extending hole column 44, the hole column 44 is sleeved with a spring 62, and the height of the spring 62 is higher than that of the hole column 44 in a natural state. After passing through the hole column 44 and the spring 44, the claw 611 of the piston 61 is hung at the terminal end of the spring 44 through a limiting piece 45.

Referring to fig. 11 and 12, when the tap water pipe is normally supplied with water, the piston 61 of the anti-siphon assembly 6 is in a closed state by the spring 62; when the tap water pipeline generates negative pressure, the piston 61 moves downwards against the elasticity of the spring 62 under the action of the negative pressure, and at the moment, the piston 61 is opened to enable the pipeline to be communicated with the atmosphere, so that the vacuum environment in the pipeline is destroyed, and water cannot flow back.

Referring to fig. 6, the water tank 1 is provided with a circuit board 7 for controlling the flushing system. The water pump 2, the reversing valve 3, the pressure sensor and the electromagnetic pilot valve 5 respectively form a control loop with a control flushing system circuit board 7. The overflow port 13 is arranged on the water tank 1, so that the water tank 1 is prevented from being full due to the failure of the water inlet valve, and the toilet is immersed. If the water tank 1 is full, water can flow out from the overflow port 13, and water flowing out from the overflow port 13 can be directly led into the ceramic pan surface of the closestool and discharged from the sewer.

The flushing structure of the toilet bowl adopting the scheme has two working modes:

first, referring to fig. 4, when the pressure sensor senses that the tap water pressure is greater than or equal to 0.12MPA, the suspended iron 55 controlled by the solenoid valve 51 leaves the pressure relief hole 511, the pressure relief hole 511 is opened, water at the water inlet end of the valve seat 50 flows in through the water passing small hole 504 and flows into the diaphragm cavity 503 through the overflow hole 512, at this time, a large pressure difference is formed at the end cover 53, so that the water pressure at the water outlet end 501 pushes up the end cover 53, and water flows out from the water outlet end 502, and enters the water flow brush waterway L1 after passing through the three-way valve 4. Meanwhile, the water in the water tank is pumped by the water pump and flows into the flushing-assisting water path L2 through the reversing valve 3, so that the flushing water path L1 and the flushing-assisting water path L2 respectively controlled by tap water and the water tank work simultaneously, and a relatively ideal flushing effect is achieved. The flushing mode can save water in the water tank because of the diversion of the flushing and the flushing assisting, and has outstanding effects and advantages when the toilet is required to be continuously flushed.

Referring to fig. 5, when the pressure sensor senses that the tap water pressure is less than 0.12MPA, the pressure relief hole 511 is blocked by the suspended iron 55 controlled by the solenoid valve 51, the pressure relief hole 511 is closed, the inflow of the inflow end of the valve seat 50 through the water passing small hole 504 is impossible, the pressure in the diaphragm chamber 503 is impossible to be released, so that a great downward pressure is generated on the end cover 53, thereby closing the inflow end 501 of the valve seat 50, and at this time, the tap water pipe cannot supply water to the flushing waterway. Meanwhile, the flushing system circuit board 7 controls the reversing valve 3 to firstly open a passage between the water supply of the water pump 2 and the flushing waterway L1, and then to open a passage between the flushing circuit board and the flushing assisting waterway L2 after finishing flushing, so that a comparatively ideal flushing effect is achieved by adopting a mode of flushing firstly and then assisting flushing. This approach is suitable for use environments where water pressure is low or unstable.

The above-mentioned toilet bowl flushing structure is all set up in the ceramic pedestal of closestool, and it is especially worth mentioning that water tank 1 locates the rear side of ceramic pedestal through the embedded mode, like this, when ceramic pedestal is at the shaping, just need not to consider and form out the ceramic water tank that accords with airtight condition at ceramic pedestal rear side, can reduce ceramic pedestal shaping precision requirement to reduce technology cost.

The above embodiments are only for illustrating the technical idea of the present utility model, and the protection scope of the present utility model is not limited thereto, and any modifications and equivalent substitutions made on the basis of the technical scheme according to the technical idea of the present utility model fall within the protection scope of the present utility model.
