Description

Technical Field

[0001] The utility model relates to the field of bathrooms, in particular to a flushing system and a toilet. Background Art

[0002] There are generally two types of toilet flushing systems on the market. The first type is a side-flush single-circuit flush, where water flows out from the side ring surface of the inner wall of the toilet body for flushing. The second type is a dual-circuit flush, where one water path flows out from the side ring surface of the inner wall of the toilet body for brushing the ring, and the other water path is sprayed from the bottom of the toilet body. Most of the current dual-circuit flushing systems use solenoid valves to switch the water paths. Their structure is complex and they often cannot be used due to power outages, which has obvious disadvantages. One flushing system in the prior art uses a water pump to draw water from the water tank through a three-way assembly to simultaneously supply water to the brush ring nozzle and the main flush nozzle assembly to achieve flushing without the use of a solenoid valve. However, the above method requires the opening of a new three-way assembly and nozzle assembly, which is costly. In addition, the above structure does not provide an anti-siphon port at the rear end of the flushing pipeline. After the pump flushes, siphon backflow or gas backflow from the siphon port is prone to occur, causing gurgling sounds. Utility Model Content

[0003] The utility model aims to solve the technical problems existing in the prior art and provides a flushing system and a toilet, which have a simple and compact structure and low cost and can effectively solve the anti-siphonage and noise problems.

[0005] Furthermore, the water distribution member is located at the top of the water tank and connected to the side wall of the water tank.

[0006] Furthermore, the water diversion component is provided with an anti-siphon hole communicating with the water diversion cavity.

[0007] Furthermore, the anti-siphon hole is a tiny hole and is connected to the inner cavity of the water tank, so that when water flows out of the anti-siphon hole, the water can flow into the water tank.

[0008] Furthermore, the anti-siphon hole is located on the side wall of the water distribution component, and the water distribution component is provided with a drainage groove corresponding to the anti-siphon hole.

[0010] Furthermore, the water supply port is located on the top wall of the water distribution component, and a movable valve core is installed in the water supply port. When the water pump discharges water, the movable valve core is acted upon by water pressure to close the water supply port. When the water supply pipe discharges water, the movable valve core is acted upon by water pressure to open the water supply port.

[0011] Furthermore, the water distribution component includes a water distribution component body with an opening at the upper end and an upper cover. The water distribution component body is connected to the water tank, and the upper cover and the upper end of the water distribution component body are connected and enclose a water distribution cavity; the water inlet, main flushing port and brush ring port are respectively arranged on the water distribution component body, and the water replenishment port is arranged on the upper cover and is connected to a water replenishment joint.

The flushing system of the utility model adopts the method of setting the water distribution component on the water tank, so that the structure of the flushing system is simple and compact, and there is no need to provide a separate three-way component, thereby reducing the manufacturing cost of the product.

[0016] 2. The water distribution component is equipped with an anti-siphon hole connected to the water distribution chamber, so that the front-end gas can be discharged through the anti-siphon hole when the water pump is working. At the same time, the water overflowing from the anti-siphon hole can flow directly back to the water tank without the need for an additional connecting hose. After the water pump finishes working, the gas can enter the pipeline through the anti-siphon hole, thereby effectively solving the anti-siphon and noise problems.

[0017] 3. A drainage groove is provided at the water distribution piece corresponding to the anti-siphon hole to drain the water flowing out of the anti-siphon hole to the water tank through the drainage groove to prevent the water flowing out of the anti-siphon hole from flowing out of the water tank.

[0036] See Figures 1-9 As shown, the flushing system of the present invention includes a water tank 1, a water pump 2, a main flushing pipeline 4, and a brush ring pipeline 5. The water inlet of the water pump 2 is connected to the water tank 1. It also includes a water distribution member 3 disposed on the water tank 1. The water distribution member 3 has a closed water diversion chamber 33 and a water inlet 311, a main flushing port 312, and a brush ring port 313 connected to the water diversion chamber 33. The water inlet 311 is connected to the water outlet of the water pump 2, the main flushing port 312 is connected to one end of the main flushing pipeline 4, and the brush ring port 313 is connected to one end of the brush ring pipeline 5. Specifically, the water distribution member 3 is located at the top of the water tank 1 and connected to the side wall of the water tank 1.

[0037] The water distribution member 3 is provided with an anti-siphon hole 321 that communicates with the water distribution chamber 33. This small hole connects to the inner cavity of the water tank 1, allowing water to flow into the water tank 1 when it exits. The anti-siphon hole 321 is located on the sidewall of the water distribution member 3. A drainage groove 314 is provided on the water distribution member 3 corresponding to the anti-siphon hole 321.
