Description

Technical Field

[0001] This invention relates to the field of toilet technology, specifically to a noise reduction structure for a water inlet valve. Background Technology

[0002] In modern life, the user experience of the toilet is a crucial factor in assessing home comfort. The toilet's inlet valve, as its core component, refills the toilet tank after each flush. However, a common problem with most inlet valves on the market is that the water flow directly impacts the water surface. This design causes the water to collide violently with the surface as it enters the tank at high speed, producing a noticeable rushing sound. Within the relatively enclosed and confined space of the tank, this sound is amplified, ultimately becoming a significant noise level. This loud or jarring noise negatively impacts the toilet experience.

[0003] Therefore, this application studies a noise reduction structure for a water inlet valve, which can reduce the noise during the water inlet process and has a simple structure. Utility Model Content

[0004] In order to reduce the noise during the water intake process of the inlet valve and to simplify the structure, this application provides a noise reduction structure for the inlet valve.

[0005] This application provides a noise reduction structure for an inlet valve, which adopts the following technical solution:

[0006] A noise reduction structure for a water inlet valve includes a valve body having an inlet channel and an outlet channel that are interconnected. The outlet channel is provided with a guide section and a guide section, and water flows out of the outlet channel sequentially through the guide section and the guide section. The valve body also includes a pipe body, in which the inlet channel is formed, and the outlet channel is located on the outer wall of the pipe body.

[0007] By adopting the above technical solution, the water flow can flow orderly along the water guide and water inlet when entering the water tank, avoiding the water flow from directly impacting the water surface and causing violent collisions. This effectively reduces the noise generated by the water flow hitting the water surface, solves the problem of the water inlet valve being noisy during the water intake process, improves the toilet experience, and has a simple structure.

[0008] Optionally, the angle between the water guiding part and the water intake part is 0-180 degrees.

[0009] Optionally, the water intake section includes water intake ribs disposed on the outer wall of the pipe body, the water intake ribs extending along the length direction of the pipe body; the water guide section includes an inclined water guide channel, the outlet of the inclined water guide channel facing the water intake ribs.

[0010] Optionally, both sides of the water-guiding rib are provided with inclined water-guiding grooves, the two inclined water-guiding grooves are in a "V" shape and the outlets of the two inclined water-guiding grooves are facing the water-guiding rib.

[0011] By adopting the above technical solution, the water flow can be guided more effectively, allowing the water flow to be more smoothly dispersed before entering the water-guiding ribs, reducing the concentrated impact of the water flow, further reducing the impact force of the water flow on the water surface, thereby effectively reducing noise and improving the noise reduction effect.

[0012] Optionally, the water outlet channel is further provided with a water passage hole and a flow buffer. The water passage hole is connected to the water inlet channel, and the flow buffer is connected to the inclined guide channel. The flow buffer is located below the water passage hole, and the flow buffer has an opening on the side facing the water passage hole. Water from the water passage hole enters the flow buffer through the opening, and water from the flow buffer overflows from the opening into the inclined guide channel.

[0013] By adopting the above technical solution, the slow-flow trough can effectively slow down the speed of the water flow, allowing the water to enter the inclined guide trough more smoothly, further reducing the turbulence and impact of the water flow when entering the inclined guide trough, thereby reducing noise and improving the noise reduction effect.

[0014] Optionally, the slow-flow channel is located between adjacent inclined guide channels, and the inlets of the inclined guide channels are located on both sides of the slow-flow channel. The water flow from the inlet channel flows through the water passage through the slow-flow channel into the inclined guide channel, and then flows to the water guide ribs.

[0015] By adopting the above technical solution, the water flow can transition more smoothly before entering the water intake ribs, reducing water turbulence and impact, further reducing noise, and enhancing the noise reduction effect.

[0016] Optionally, the water guide includes an arc-shaped surface with an arcuate shape. The bottom of the arcuate surface is close to the outer wall of the pipe. The water outlet channel is also provided with a water passage hole. The water passage hole is provided along the end face of the pipe and is connected to the water inlet channel. The arcuate surface is located below the water passage hole. The water flowing through the water passage hole flows down the outer wall of the pipe after passing through the arcuate surface.

[0017] By adopting the above technical solution and setting the arc-shaped surface, the water flow can smoothly transition to the outer wall of the pipe, thereby improving the noise reduction effect.

[0018] Optionally, the water intake section includes water intake ribs disposed on the outer wall of the pipe body. The water intake ribs extend along the length direction of the pipe body. The two sides of the arc-shaped surface are close to the adjacent water intake ribs and bend toward the water intake ribs to form an arc-shaped surface that is high in the middle and low on both sides. The arc-shaped surface gradually bends toward the outer wall of the pipe body along the water flow direction.

[0019] Optionally, at least two water guide sections are provided around the perimeter of the water outlet channel.

[0020] By adopting the above technical solution, the impact force of the water flow is dispersed in one step, reducing the concentrated impact of the water flow on the water surface, thereby effectively reducing noise and improving the noise reduction effect.

[0021] Optionally, it also includes a control valve for controlling the opening and closing of the water inlet channel and the water outlet channel, wherein the control valve is a mechanical valve or an electrically controlled valve.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. It allows water to flow orderly along the guide section and the inlet section when entering the water tank, avoiding the water flow from directly impacting the water surface and causing violent collisions. This effectively reduces the noise generated by the water flow hitting the water surface, solves the problem of the water inlet valve being noisy during the water intake process, improves the toilet experience, and has a simple structure.

[0024] 2. The “V” shaped structure can guide the water flow more effectively, allowing the water flow to be more smoothly dispersed before entering the water guide bars, reducing the concentrated impact of the water flow, further reducing the impact force of the water flow on the water surface, thereby effectively reducing noise and improving the noise reduction effect;

[0025] 3. The slow-flow trough can effectively slow down the water flow, allowing the water to enter the inclined guide trough more smoothly, further reducing turbulence and impact when the water enters the inclined guide trough, thereby reducing noise and improving the noise reduction effect.

[0026] 4. It can gradually slow down the water flow when it enters the water tank, reduce the impact force of the water flow, and further reduce the impact of the water flow on the water surface, thereby effectively reducing noise and improving the noise reduction effect.

[0027] 5. The curved surface design allows the water flow to smoothly transition to the outer wall of the pipe, improving the noise reduction effect. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a noise reduction structure for a water inlet valve. (Refer to...) Figure 1 and Figure 2 The noise reduction structure of the inlet valve includes a valve body with an interconnected inlet channel 1 and an outlet channel 2. The outlet channel 2 is equipped with a guide section 3 and a guide section 4. The water flow in the outlet channel 2 flows out through the guide section 3 and the guide section 4 in one pass, allowing the water to flow orderly along the guide section 3 and the guide section 4 when entering the water tank. This avoids the water flow directly impacting the water surface and causing violent collisions, thus effectively reducing the noise generated by the water flow hitting the water surface. The valve body also includes a pipe 5, with the inlet channel 1 formed inside the pipe 5 and the outlet channel 2 formed outside the pipe 5.

[0038] In some embodiments, the angle between the water guide section 3 and the water inlet section 4 is 0-180 degrees.

[0039] In some embodiments, at least two water guide sections 3 are provided around the perimeter of the water outlet channel 2.

[0040] In some embodiments, a control valve 6 is also included to control the opening and closing of the water inlet channel 1 and the water outlet channel 2. The control valve 6 is used to control the water inlet and outlet of the valve body and is either a mechanical valve or an electrically controlled valve.

[0041] In some embodiments, the water inlet 4 includes a water inlet rib provided on the outer wall of the pipe body 5, the water inlet rib extending along the length of the pipe body 5; the water guide 3 includes an inclined water guide channel, the outlet of which faces the water inlet rib.

[0042] In some embodiments, inclined guide channels are provided on both sides of the water-guiding rib, forming a "V" shape, and the outlets of both inclined guide channels face the water-guiding rib. In this embodiment, two sets of inclined guide channels with a "V" shape are provided, symmetrically arranged along the central axis of the pipe body 5. This allows for better water guidance, slows down the flow rate, disperses the water flow, and avoids noise generated by direct impact.

[0043] In some embodiments, the water outlet channel 2 is further provided with a water passage hole 9 and a flow-retarding groove 7. The water passage hole 9 is connected to the water inlet channel 1, and the flow-retarding groove 7 is connected to the inclined guide channel. The flow-retarding groove 7 is located below the water passage hole 9, and the side of the flow-retarding groove 7 facing the water passage hole 9 has an opening. Water from the water passage hole 9 enters the flow-retarding groove 7 through the opening, and water from the flow-retarding groove 7 overflows into the inclined guide channel. This further slows down the water flow, allowing it to enter the inclined guide channel more smoothly and improving the noise reduction effect. In this embodiment, one end of the pipe body 5 is connected to a sealing rib 8, and several water passage holes 9 are spaced apart along the sealing rib 8. After water enters the pipe body 5, it flows out through the water passage hole 9 to the flow-retarding groove 7 outside the pipe body 5, and the flow-retarding groove 7 overflows into the inclined guide channel.

[0044] In some embodiments, the flow-retarding channel 7 is located between adjacent inclined guide channels, with the inlets of the inclined guide channels located on both sides of the flow-retarding channel 7. The water flow from the inlet channel 1 flows through the water passage 9, passes through the flow-retarding channel 7, and flows into the inclined guide channel, then flows towards the water guide ribs. In this embodiment, the inclined guide channel with the "V"-shaped structure extends in a straight line near the opening. After the water flows out of the flow-retarding channel 7, it flows into the "V"-shaped structure along the straight lines on both sides.

[0045] Reference Figures 3-5 In other embodiments, the water guide 3 includes an arc-shaped surface with its bottom close to the outer wall of the pipe body 5. The water outlet channel 2 is also provided with a water passage hole 9, which is located along the end face of the pipe body 5 and connected to the water inlet channel 1. The arc-shaped surface is located below the water passage hole 9, and the water flowing through the water passage hole 9 flows down the outer wall of the pipe body 5 after passing through the arc-shaped surface. In this embodiment, the arc-shaped surface and the water passage hole 9 are correspondingly arranged, and the water flows out from the water passage hole 9 into the arc-shaped surface, which makes the water flow more gently and improves the noise reduction effect.

[0046] In some embodiments, the water guiding section 4 includes water guiding ribs disposed on the outer wall of the pipe body 5. The water guiding ribs extend along the length direction of the pipe body 5. The two sides of the arc-shaped surface are respectively close to the adjacent water guiding ribs and bend towards the water guiding ribs to form an arc surface that is high in the middle and low on both sides. The arc-shaped surface gradually bends towards the outer wall of the pipe body 5 along the water flow direction. That is, in this embodiment, the diameter of the arc-shaped surface gradually decreases in the direction away from the water passage hole 9, so as to better guide water and improve the noise reduction effect.

[0047] The implementation principle of the noise reduction structure of the water inlet valve in this application embodiment is as follows: when the water flows into the water tank, it can flow orderly along the water guide part 3 and the water inlet part 4, avoiding the water flow directly impacting the water surface and causing violent collisions, thereby effectively reducing the noise generated by the water flow hitting the water surface, solving the problem of the water inlet valve having a large noise during the water intake process, improving the toilet experience, and the structure is simple.
