Description

Technical Field

[0001] The utility model relates to the technical field of toilet tank water inlet valves, in particular to a silent structure of a water inlet valve. Background Art

[0002] The toilet water tank is filled with water through an inlet valve. The inlet valve has an inlet valve body. The inlet valve body has a water inlet and a water outlet. The water inlet is connected to a household water pipe network, and the water outlet is located in the toilet water tank. A buoyancy control mechanism is provided on the inlet valve body. When the water level in the toilet water tank is lower than a predetermined height, the buoyancy control mechanism connects the inlet valve body with the water inlet and the water outlet, thereby allowing water in the household water pipe network to enter the toilet water tank. When the water level in the toilet water tank reaches a predetermined height, the buoyancy control mechanism causes the inlet valve body to cut off the connection between the water inlet and the water outlet, thereby stopping the toilet water tank from taking in water.

[0003] Usually, the water outlet on the water inlet valve body is at a certain height from the bottom of the toilet tank. When the water flowing out of the water outlet falls freely into the toilet tank, it will produce impact and make a loud noise. This noise accompanies the entire water inlet process and affects the sleep of family members when used at night.

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the claims, specification and the above-mentioned drawings of the present invention, unless otherwise explicitly defined, directional words, such as the use of terms such as "center", "lateral", "longitudinal", "horizontal", "vertical", "top", "bottom", "inside", "outside", "up", "down", "front", "back", "left", "right", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as limiting the specific protection scope of the present invention.

[0025] The utility model provides a silent structure of a water inlet valve, such as Figure 1-5 As shown, it includes an inlet valve body 1, and the inlet valve body 1 can be any existing structure of a toilet inlet valve, without specific limitation. A water outlet 2 is provided on the inlet valve body 1, and the inlet valve body 1 fills water into the toilet tank through the water outlet 2. The above content is a conventional design in this field and is not described in detail. A water outlet pipe 3 is provided below the water outlet 2 of the inlet valve body 1, and the top end of the water outlet pipe 3 can be connected to the inlet valve body 1, or can be spaced from the inlet valve body 1, without specific limitation, as long as the top end of the water outlet pipe 3 can be used for the water flowing out of the water outlet 2 to enter. A preferred embodiment is given later. The bottom end of the water pipe 3 extends downward and then leads into the toilet water tank. A guide portion 5 is provided in the water outlet pipe 3. The guide portion 5 has a guide cone 6 located in the center of the water outlet pipe 3. The center mentioned in this article refers to the center of the radial cross section of the water pipe, that is, the position of the central axis, which is the usual meaning when describing a tubular member. The guide cone 6 is convex in the middle and inclined downward on all sides. Preferably, the guide cone 6 is a hemispherical surface, and of course it can also be a pyramid surface, a conical surface or other shapes, without specific limitation. There is a water gap 7 between the guide cone 6 and the inner wall of the water outlet pipe 3; more specifically, a water distribution plate 4 is formed on the guide portion 5, and the top surface of the water distribution plate 4 is the guide cone 6;

[0026] Furthermore, the following effects can be achieved during operation: the water flow discharged from the water outlet 2 enters the water outlet pipe 3 from the top of the water outlet pipe 3, and then the water flow flows downward from the water outlet pipe 3, wherein part of the water flow is close to the inner wall of the water outlet pipe 3, and this part of the water flow will flow downward under the guidance of the inner wall of the water outlet pipe 3, while the other part of the water flow is located in the center of the water outlet pipe 3, and this part of the water flow is not guided by the inner wall of the water outlet pipe 3 and falls freely until it falls on the guide cone 6. Since the middle part of the guide cone 6 is convex and the surrounding parts are downwardly inclined, this part of the water flow can be diffused to the surroundings, and the diffused water flow flows to the inner wall of the water outlet pipe 3, and then after passing through the water gap 7, it continues to flow downward under the guidance of the inner wall of the water outlet pipe 3, so that the water flow in the water outlet pipe 3 can flow into the toilet tank in an orderly manner under the guidance of the inner wall of the water outlet pipe 3, thereby reducing the turbulence and impact when the water flows into the toilet tank, thereby achieving a silent effect. It can be seen from the above working process that when water flows onto the guide cone surface 6 of the guide part 5 , a certain impact will still be generated. Therefore, in order to alleviate the impact at this time, it is preferred that the guide part 5 is located at the top of the water outlet pipe 3 .

[0027] In order to reduce the turbulence before the water reaches the guide cone 6, it is preferred that the guide part 5 is also provided with a plurality of guide plates 8 above the guide cone 6. The plurality of guide plates 8 separate the outlet pipe 3 into a plurality of longitudinal water passages 9. After being separated into a plurality of longitudinal water passages 9, the water at each position enters the longitudinal water passages 9 at the corresponding position respectively, so as to realize the diversion of the water flow, play the role of dredging the water flow and reducing turbulence. More preferably, each of the guide plates 8 is arranged in a circular array around the axis of the outlet pipe 3, and / or is arranged longitudinally perpendicular to the inner wall of the outlet pipe 3, so as to better match the shape of the guide cone 6 and reduce the impact of the water flow. Of course, the guide plates 8 can also be designed to be inclined or curved. More preferably, the bottom ends of each of the guide plates 8 are respectively connected to the top surface of the guide cone 6, which can also slow down the turbulence when the water flows fall onto the guide cone 6. More preferably, the top edge of each of the guide plates 8 is chamfered 10 to reduce the turbulence caused by the impact of the water flow on the guide plates 8.

[0028] Preferably, the top end of the water outlet pipe 3 is connected to the water inlet valve body 1. The top end of the water outlet pipe 3 is sealedly connected to the water inlet valve body 1, and the connection and sealing can reduce the transmission of noise in the water outlet pipe 3 to the outside.

[0029] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
