Description

Technical Field

[0001] This utility model relates to water tanks, and more particularly to a toilet flushing water tank. Background Technology

[0002] Many toilet tank flushing solutions on the market that combine inlet valves with water pumps have issues. Because the water level is low when the pump is pumping, the outlet of the inlet valve is fully exposed after pumping. When water enters the inlet valve, the water flow impacts the side wall of the tank, generating significant noise. Furthermore, there is often a height difference between the lowest surface of the tank bottom and the inlet valve installation position. When the pump is pumping, the water flow impacts the side wall of the tank and falls into the bottom wall, causing even more noise. Summary of the Invention

[0003] To overcome the shortcomings of the prior art described in the background section, the present invention provides a toilet flushing tank, comprising a tank placed inside the toilet, an inlet valve for supplying water to the tank on the bottom wall of the tank, an outlet at the bottom of the inlet valve, an outlet at the bottom of the tank for connecting to a toilet flushing pump, and a baffle plate extending upward from the bottom wall of the tank. The baffle plate or the baffle plate and the side wall of the tank can form a water storage cavity around the inlet valve, such that the outlet of the inlet valve is submerged in the water storage cavity.

[0004] Furthermore, the top of the baffle plate is higher than the outlet of the inlet valve.

[0005] Furthermore, the bottom of the water tank is provided with an outlet for connecting to a toilet water pump.

[0006] Furthermore, the bottom wall of the water tank is provided with a first bottom wall and a second bottom wall in a stepped shape, the first bottom wall being higher than the second bottom wall, and the water inlet valve being installed on the first bottom wall.

[0007] Furthermore, the water baffle extends upward from the first bottom wall.

[0008] Compared with the prior art, the technical solution adopted in this utility model has the following advantages:

[0009] By installing a baffle plate inside the toilet flush tank, the baffle plate or the baffle plate and the side wall of the tank can form a water storage cavity around the inlet valve, and the outlet of the inlet valve is submerged in the water storage cavity; after the water pump draws water to flush the toilet, when water enters the inlet valve, the water flowing out of the outlet will be buffered by the water in the water storage cavity, thereby reducing the noise of water entering the toilet. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the overall structure of the toilet flushing tank of this utility model;

[0011] Figure 2This is a cross-sectional schematic diagram of the toilet flushing tank of this utility model. Detailed Implementation

[0012] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1-2 As shown, the toilet flushing tank of this utility model includes a tank 1 placed inside the toilet. The bottom wall of the tank has a stepped first bottom wall 11 and a second bottom wall 12, with the first bottom wall 11 being higher than the second bottom wall 12. A water inlet valve 2 for supplying water to the tank 1 is installed on the first bottom wall 11. The higher position of the first bottom wall 11 provides operating space for the water inlet valve 2. The bottom of the water inlet valve 2 has a water outlet 21. The bottom of the tank 1 also has an outlet 13 connected to a toilet flushing pump 3. When the toilet is flushed, the pump 3 operates, and water in the tank 1 flows from the outlet 13 to the toilet for flushing. When the toilet is flushed, the pump 3 stops, and the remaining water level in the tank 1 is lower than the first bottom wall 11.

[0014] The water tank 1 is equipped with a baffle plate 14 extending upward from the first bottom wall 11. The baffle plate 14 surrounds the water inlet valve 2 to form a water storage cavity, and the top of the baffle plate 14 is higher than the outlet 21 of the water inlet valve 2, so that the outlet 21 of the water inlet valve 2 is submerged in the water storage cavity. When water enters the water inlet valve 2, the water flowing out of the outlet 21 is buffered by the water in the water storage cavity, thereby reducing the noise of water entering the tank. Of course, the baffle plate can also form a water storage cavity around the water inlet valve 2 with the side wall of the water tank. Similarly, the outlet 21 of the water inlet valve 2 will also be submerged in the water storage cavity, thus reducing the noise of water entering the tank.

[0015] In the initial state, the water tank is filled with water. When the toilet is flushed, the water pump 3 works to draw water from the water tank 1, and the water level in the water tank 1 will drop below the first bottom wall 11. However, the water storage chamber will still be full of water at this time. When the inlet valve 2 supplies water to the water tank 1 again, the water flowing out of the outlet 21 will be buffered by the water in the water storage chamber, thereby reducing the water intake noise.

[0016] The toilet flushing tank provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
