Description

Technical Field

[0001] The utility model relates to the field of toilets, in particular to a water inlet structure of a toilet. Background Art

[0002] When the existing toilet is flushed, a water path switching device is used to control whether the toilet discharges brush ring water or jet water. The brush ring water is used to wash the inner wall of the toilet bowl, and the jet water is used to wash the bottom of the toilet bowl to form a siphon in the toilet. However, the impact force of the jet water output by the existing toilet is sometimes insufficient, and the siphon cannot be formed quickly, which extremely affects the flushing effect of the toilet.

[0003] In view of the existence of the above problems, it is necessary to study a water inlet structure of a toilet, which can improve the flushing effect of the toilet. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a water inlet structure of a toilet, which can improve the flushing effect of the toilet.

[0005] To achieve the above purpose, the solution of the utility model is:

[0006] A water inlet structure of a toilet, which comprises a tee inlet pipe, a water inlet valve and a control valve. The tee inlet pipe has a communicating water inlet, a first water outlet and a second water outlet. The water inlet end of the water inlet valve is communicated with the first water outlet. The control valve is fitted to the tee inlet pipe, and the water inlet end of the control valve is communicated with the second water outlet. The water outlet end of the control valve is used for connecting the flushing pipeline of the toilet.

[0007] The control valve adopts a pilot-operated control valve.

[0008] The water inlet valve is provided with a water replenishing port, and the water replenishing port is used for connecting the flushing pipeline of the toilet.

[0009] After adopting the above scheme, the working principle of the utility model is as follows: the water inlet of the tee inlet pipe is used for accessing an external water source; when the toilet is flushed, the control valve is opened, so that the water flow of the external water source flows into the flushing pipeline of the toilet through the control valve. At the same time, the water flow in the toilet water tank also flows into the flushing pipeline of the toilet (this is the prior art). In this way, the water output by the flushing pipeline converges the water flow in the water tank and the water flow of the external water source, so that the flushing pipeline can output a jet water flow with a large impact force, thereby enabling the toilet to form a siphon faster and improving the flushing effect of the toilet.

[0014] Label description: Tee inlet pipe 1, water inlet 11, first water outlet 12, second water outlet 13, inlet valve 2, water replenishing port 21, control valve 3. Specific embodiments

[0015] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail below through specific embodiments.

[0016] As Figures 1 to 4 shown, the present utility model discloses a water inlet structure of a toilet, which includes a tee inlet pipe 1, an inlet valve 2 and a control valve 3. The tee inlet pipe 1 has a communicating water inlet 11, a first water outlet 12 and a second water outlet 13. The water inlet end of the inlet valve 2 is communicated with the first water outlet 12. The control valve 3 is cooperated with the tee inlet pipe 1, and the water inlet end of the control valve 3 is communicated with the second water outlet 13. The water outlet end of the control valve 3 is used to connect the flushing pipeline of the toilet.

[0017] The working principle of the present utility model is as follows: The water inlet 11 of the tee inlet pipe 1 is used to connect to an external water source; when the toilet is flushed, the control valve 3 is opened, so that the water flow of the external water source flows into the flushing pipeline of the toilet through the control valve 3. At the same time, the water flow in the toilet water tank also flows into the flushing pipeline of the toilet (this is the prior art). In this way, the water output by the flushing pipeline converges the water flow in the water tank and the water flow of the external water source, so that the flushing pipeline can output a jet water flow with a large impact force, thereby enabling the toilet to form a siphon faster and improving the flushing effect of the toilet. When the water tank of the toilet needs to be filled with water, the control valve 3 is closed and the inlet valve 2 is opened, so that the water flow of the external water source flows into the toilet water tank through the inlet valve 2, filling the toilet water tank.

[0018] In the embodiment of the present utility model, the control valve 3 adopts a pilot-operated control valve 3, and the pilot-operated control valve 3 has the advantages of labor-saving switching, low power consumption, energy saving and power saving.

[0019] In the embodiment of the present utility model, the inlet valve 2 is provided with a water replenishing port 21, and the water replenishing port 21 is used to connect to the flushing pipeline of the toilet. In this way, while the inlet valve 2 introduces the water flow of the external water source into the water tank, the inlet valve 2 also introduces the water flow of the external water source into the flushing pipeline, so that the flushing pipeline discharges water and a water seal is formed at the bottom of the toilet pan, preventing the odor in the sewage pipe from entering the room through the toilet.

[0020] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those of ordinary skill in the art shall be regarded as not departing from the patent scope of the present utility model.
