Problems solved by technology

[0003] As the toilet is becoming more and more intelligent, some control components in the water tank of the toilet can be controlled by hydraulic pressure. When hydraulic control is used, a water inlet valve is required to supply water to it, but the existing water inlet valve cannot stop Provides water intake for a long time (≥1S) after water, so it is necessary to improve the existing water intake valve

Embodiment 1

[0053] Such as Figure 1-9 As shown, the first embodiment of the present invention provides a delayed water inlet mechanism, including a water inlet valve and a delay assembly 4, the water inlet valve is a commonly used water inlet valve, including a valve part 1, a seal 2 and a water level control Component 3.

[0054] The water inlet valve is made of hard material. In this embodiment, the water inlet valve is used in the toilet tank. Therefore, it is preferably made of a corrosion-resistant plastic material.

[0055] The valve portion 1 includes a pressure relief port 11, and the seal 2 is used to seal the pressure relief port 11. The seal 2 may be a commonly used sealing device. In this embodiment, a rubber gasket is used. Those skilled in the art can choose other sealing materials.

[0056] The water level control assembly 3 drives the sealing element 2 to act, and the position where the sealing element 2 and the pressure relief port 11 are sealed and matched is the sealing posi...

Embodiment 2

[0081] Such as Figure 10-18 As shown, the second embodiment of the present invention provides a delayed water intake mechanism, which includes a water intake valve and a delay assembly 4, and the water intake valve includes a valve portion 1, a seal 2 and a water level control assembly 3.

[0082] The valve portion 1 includes a pressure relief port 11, and the seal 2 is used to seal the pressure relief port 11. The seal 2 may be a commonly used sealing device. In this embodiment, a rubber gasket is used.

[0083] The water level control assembly 3 drives the sealing element 2 to act, and the position where the sealing element 2 and the pressure relief port 11 are sealed and matched is the sealing position, and the sealing element 2 is separated from the pressure relief port 11 The position at is the pressure relief position, and the water level control assembly 3 includes a floating body 31 and a seal control mechanism 32 connected by the floating body 31.

Embodiment 3

[0101] Such as Figure 19-23 As shown, the third embodiment of the present invention provides a water inlet valve with a delayed water stop function. The structure provided in this embodiment is basically the same as that provided in the second embodiment. The difference is that in this embodiment, the delay The assembly 4 includes: the cavity of the delay assembly 4 is a third cylinder 48 provided with the first through hole 411, and the cavity adjustment assembly includes a cavity that is arranged inside the third cylinder 48 and The second piston 491, which can reciprocate along the axis, and the middle part are fixedly connected to the second piston 491. The two ends of the second piston rod 492 respectively penetrated from both ends of the third cylinder 48, the second The end of the piston rod 492 away from the first through hole 411 is connected to the rod 321 of the water level control assembly 3, and the second piston 491 and the third cylinder 48 form an inner end clo...

Abstract

The invention relates to a delayed water inlet mechanism, and relates to the technical field of water inlet valves. A water inlet valve and a delay assembly are included. The delay assembly acts on the water inlet valve and is used for making the water inlet valve closed in a delayed manner when external force controls the water inlet valve to be opened. The delayed water inlet mechanism is simplein structure and high in reliability. Through the additionally-arranged delay assembly, after water stop of the water inlet valve, the water inlet valve can provide water inflow for a long time larger than or equal to 1S under driving of external force, and the self water stop performance is not influenced.

Description

Technical field [0001] The invention relates to the technical field of water inlet valves, in particular to a delayed water inlet mechanism. Background technique [0002] The inlet valve in the existing toilet products is connected with a float and a lifting rod. After the inlet valve stops water, press the inlet valve float to open the inlet valve. Due to buoyancy, the float rises and drives the sealing assembly to close the inlet valve The pressure relief port and the water inlet valve stop water. [0003] As the toilet becomes more and more intelligent, some control components in the toilet tank can be controlled by hydraulic pressure. When hydraulic control is used, a water inlet valve is required to supply water to it, but the existing water inlet valve cannot stop. It provides a longer time (≥1S) of water inlet after water, so the existing water inlet valve needs to be improved. Summary of the invention [0004] In view of the above-mentioned problems, the present invention ...
