Description

Technical Field

[0001] This utility model belongs to the technical field of toilet tank inlet valves, specifically a silent inlet valve for toilet tanks. Background Technology

[0002] The function of the toilet tank inlet valve is to control the water replenishment process of the toilet tank. It automatically turns the water flow on or off through a water level sensor, thereby ensuring a stable water level in the tank.

[0003] Currently, when traditional inlet valves are opened or closed, water flows rapidly through the valve body, pipes, or outlet. The sudden change in flow velocity generates impact noise. If the inlet design is unreasonable, the water flow cross-section may suddenly shrink or expand, leading to turbulence and pressure fluctuations. When the water level control device is activated, it may suddenly cut off or open the water flow, causing water hammer effect.

[0004] Therefore, it is urgent to develop a toilet tank silent inlet valve that is highly reliable, has a large water flow rate, and is unaffected by water pressure. The purpose of this utility model is to provide a toilet tank silent inlet valve to solve the problems mentioned in the background art. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the technical problem of developing a silent inlet valve for toilet tanks mentioned in the background art, the technical solution adopted by this utility model is as follows: The silent inlet valve for toilet tanks of this utility model includes an inlet valve body, with a water-blocking component at the top of the inlet valve body; a telescopic component at the bottom of the inlet valve body; and a floating mechanism in the middle of the inlet valve body. Through the above structure, the silent upgrade of the toilet inlet valve body is not only an optimization of a single component, but also a synergy of multiple technologies such as floating mechanism control, water flow buffering, and air resistance elimination. From structural design to material selection, the silent inlet valve achieves the integrated goal of "low-noise water replenishment, water saving and durability", providing technical guarantee for a quiet experience in the bathroom.

[0006] Preferably, the water-blocking assembly includes a water-blocking plate, a buckle, and a serrated groove; the water-blocking plate is located at the top of the water inlet valve body; the buckle is snapped onto the top of the water inlet valve body; the end of the buckle is fixedly connected to the water-blocking plate; and the water-blocking plate has a serrated groove in its middle. Through the above structure, the water-blocking plate changes the direction of the water flow, reducing the violent collision between the water flow and the bottom of the water tank or the pipe, thereby reducing vibration noise. When the water flows through the outlet pipe, the water-blocking plate blocks the water flow from directly impacting downwards, increasing the outlet pressure, so that the water flow preferentially squeezes the air in the water replenishment chamber out of the water replenishment hole quickly. After the air is expelled, the water flows evenly into the water tank through the gap between the water-blocking plate and the outlet pipe. At this time, there is no air in the chamber, avoiding the noise generated by the vibration of the water flow and the air.

[0007] Preferably, the telescopic component includes an inlet pipe and a sealing triangular pad; the inlet pipe is installed at the bottom end of the inlet valve body; the inlet pipe is height-adjustable; the bottom end of the inlet pipe is fixedly connected to the sealing triangular pad; through the above structure, a spiral structure is set on the outer wall of the inlet pipe and the inner wall of the outlet pipe, thereby guiding the water flow spirally downward, so that the water flow adheres to the pipe wall and forms a spiral falling posture, slowing down the water flow speed, avoiding collision between water and air and the pipe wall, reducing pipe vibration, and thus reducing noise.

[0008] Preferably, the floating mechanism includes a slider, a float, and an adjusting screw; the slider is slidably connected to the side wall of the inlet valve body; the float is fixedly connected to the middle of the slider; and the adjusting screw is slidably connected to the top of the float. Through the above structure, the floating mechanism can be used as the "nerve center" of the inlet valve body, and its design accuracy directly affects the water-saving performance and reliability of the toilet.

[0009] Preferably, the top of the water inlet valve body is provided with a water inlet; the inside of the water inlet is provided with a water-stopping pad; through the above structure, the arc design of the edge of the water inlet is used to disperse the impact force of the water flow, guide the water flow to enter smoothly, reduce turbulence and air entrainment, and reduce water intake noise.

[0010] Preferably, a filter screen is fixedly connected to the bottom of the water inlet valve body; through the above structure, the water inlet valve body avoids the formation of a negative pressure zone due to the structure of the filter screen when water enters, thereby achieving anti-clogging and water pressure balance.

[0011] Preferably, the water-stop pad is made of food-grade EPDM rubber; the metal parts of the water inlet are mostly made of stainless steel or electroplated. Through the above structure, the rubber has the characteristics of high elasticity and anti-aging, ensuring that it is not easy to harden or crack after long-term contact with water, thus ensuring the sealing effect of the water inlet. Stainless steel or electroplating can prevent scale adhesion and corrosion, and prevent water leakage or increased noise due to component damage.

[0012] The beneficial effects of this utility model are as follows: 1. The silent water inlet valve for toilet tank described in this utility model achieves a silent upgrade of the toilet inlet valve body through the structural design of the inlet valve body. This upgrade is not only an optimization of a single component, but also a synergy of multiple technologies such as floating mechanism control, water flow buffering, and air resistance elimination. From structural design to material selection, the silent water inlet valve achieves the integrated goal of "low-noise water replenishment, water saving and durability", providing technical guarantee for a quiet experience in the bathroom space.

[0013] 2. The silent inlet valve for a toilet tank described in this utility model, through the structural design of the baffle plate, enables the baffle plate to change the direction of water flow, reducing the violent collision between the water flow and the bottom of the tank or the pipe, thereby reducing vibration noise. When the water flows through the outlet pipe, the baffle plate prevents the water flow from impacting downwards directly, increasing the outlet pressure and causing the water flow to preferentially expel the air in the water inlet chamber from the water inlet hole quickly. After the air is expelled, the water flows evenly into the tank through the gap between the baffle plate and the outlet pipe. At this time, there is no air in the chamber, avoiding the noise generated by the vibration of water flow and air. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figure 1As shown in the embodiment of this utility model, a silent water inlet valve for a toilet tank includes an inlet valve body 1. The top of the inlet valve body 1 has a water-blocking component; the bottom of the inlet valve body 1 has a telescopic component; and the middle of the inlet valve body 1 has a floating mechanism. During operation, when the water level in the toilet drops, the water replenishment speed is determined by the falling speed of the floating mechanism. The telescopic component adjusts the inlet valve body 1 to a suitable height relative to the water tank. Then, the water-blocking component reduces noise generation when water enters the inlet valve body 1. Through this structure, the silent upgrade of the toilet inlet valve body 1 is not merely an optimization of a single component, but a synergy of multiple technologies such as floating mechanism control, water flow buffering, and air resistance elimination. From structural design to material selection, modern silent water inlet valves have achieved the integrated goal of "low-noise water replenishment, water saving, and durability," providing technical assurance for a quiet experience in the bathroom.

[0020] like Figure 4 As shown, the water-blocking assembly includes a water-blocking plate 2, a buckle 21, and a serrated groove 22; the water-blocking plate 2 is located at the top of the inlet valve body 1; the buckle 21 is snapped onto the top of the inlet valve body 1; the end of the buckle 21 is fixedly connected to the water-blocking plate 2; the water-blocking plate 2 has a serrated groove 22 in its middle; during operation, the water-blocking plate 2 is positioned inside the outlet pipe of the inlet valve body 1 via the buckle 21, near the water outlet, forming a specific distance or angle with the inner wall of the outlet pipe; the edge of the water-blocking plate 2 may be designed as a serrated groove 22, further subdivided... The structure described above reduces the impact force of the water flow by changing the direction of the water flow from "vertical impact" to "lateral dispersion". This reduces the violent collision between the water flow and the bottom of the water tank or the pipe, thus reducing vibration and noise. When the water flows through the outlet pipe, the baffle plate 2 prevents the water flow from impacting directly downwards, increasing the outlet pressure. This allows the water flow to quickly expel the air in the water supply chamber from the water supply hole. After the air is expelled, the water flows evenly into the water tank through the gap between the baffle plate 2 and the outlet pipe. At this time, there is no air in the chamber, thus avoiding noise caused by the vibration of the water flow and the air.

[0021] like Figure 3As shown, the telescopic assembly includes an inlet pipe 3 and a sealing triangular pad 31. The inlet pipe 3 is installed at the bottom of the inlet valve body 1. The inlet pipe 3 is height-adjustable. The sealing triangular pad 31 is fixedly connected to the bottom of the inlet pipe 3. During operation, when the toilet is installed, the inlet pipe 3 needs to be connected to the water supply interface. The pipe spacing varies greatly in different installation scenarios. The telescopic adjustable structure of the inlet pipe 3 can adapt to different distances by changing its length, avoiding water leakage or stress damage caused by rigid bending of the pipe. The sealing triangular pad 31 is located between the bottom interface of the inlet valve body 1 and the nut of the inlet pipe 3. The right-angled side of the sealing triangular pad 31 corresponds to the right-angled surface of the interface, and the hypotenuse faces the nut. Through the above structure, a spiral structure can be set on the outer wall of the inlet pipe 3 and the inner wall of the outlet pipe to guide the water flow spirally downward, so that the water flow adheres to the pipe wall and forms a spiral falling posture, slowing down the water flow speed, avoiding collision between water and air and the pipe wall, reducing pipe vibration, and thus reducing noise.

[0022] like Figure 2 As shown, the floating mechanism includes a slider 4, a float 41, and an adjusting screw 42. The slider 4 is slidably connected to the side wall of the inlet valve body 1. The float 41 is fixedly connected to the middle of the slider 4. The adjusting screw 42 is slidably connected to the top of the float 41. During operation, when the float 41 in the middle of the slider 4 rises or falls with the water level in the tank, the buoyancy changes, causing the adjusting screw 42 to move, thereby opening and closing the inlet valve body 1. Through the above structure, the floating mechanism can act as the "nerve center" of the inlet valve body 1, and its design precision directly affects the water-saving performance and reliability of the toilet.

[0023] like Figure 2 As shown, the top of the inlet valve body 1 is provided with a water inlet 5; the inside of the water inlet 5 is provided with a water-stop pad; during operation, when the water level in the tank drops, the float 41 drops with the water level, and the valve assembly moves upward by adjusting the screw 42, the water-stop pad disengages from the water inlet 5, and the water flows from the inlet valve body 1 through the water inlet 5, and then enters the water tank through the outlet pipe. When the water level rises to the set height, the float 41 floats up and pushes the valve assembly down, the water-stop pad seals the water inlet 5, and cuts off the water flow. The opening edge of the water inlet 5 is smooth to prevent water leakage caused by long-term wear of the water-stop pad. Through the above structure and the arc design of the edge of the water inlet 5, the impact force of the water flow is dispersed, the water flow is guided to enter smoothly, turbulence and air entrainment are reduced, and the noise of water intake is reduced.

[0024] like Figure 3 As shown, a filter screen 6 is fixedly connected to the bottom of the water inlet valve body 1. During operation, when the water flows through the filter screen 6, the flow rate is reduced by 30%, causing impurities to be deposited due to inertia. Through the above structure, the water inlet valve body 1 can avoid the formation of a negative pressure zone when water enters due to the structure of the filter screen, thereby achieving anti-clogging and water pressure balance.

[0025] like Figure 1As shown, the water-stop pad is made of food-grade EPDM rubber; the metal parts of the water inlet 5 are mostly made of stainless steel or electroplating. During operation, EPDM rubber has high elasticity and anti-aging properties, and it is not easy to harden or crack when in contact with water for a long time, ensuring the sealing effect of the water inlet 5. Stainless steel or electroplating can prevent scale adhesion and corrosion, and prevent water leakage or increased noise due to component damage.

[0026] During operation, when the water level in the toilet drops, the speed at which the floating mechanism descends determines the water replenishment opening speed. The telescopic component adjusts the inlet valve body 1 to a suitable height with the water tank. Then, the water-blocking component reduces noise generation during water intake. Through this structure, the quiet upgrade of the toilet inlet valve body 1 is not merely an optimization of a single component, but a synergy of multiple technologies including floating mechanism control, water flow buffering, and air resistance elimination. From structural design to material selection, modern silent inlet valves have achieved the integrated goal of "low-noise water replenishment, water saving, and durability," providing technical assurance for a quiet experience in the bathroom. The water-blocking plate 2 is installed inside the outlet pipe of the inlet valve body 1 via a clip 21, located near the water outlet, forming a specific distance or angle with the inner wall of the outlet pipe. 2. The edge may be designed with a serrated groove 22 to further disperse the impact force of the water flow. Through the above structure, the baffle 2 changes the direction of the water flow, changing it from "vertical impact" to "lateral dispersion," reducing the violent collision between the water flow and the bottom of the water tank or the pipe, and reducing vibration noise. When the water flows through the outlet pipe, the baffle 2 blocks the water flow from impacting directly downwards, increasing the outlet pressure and allowing the water flow to prioritize and quickly squeeze the air in the water supply chamber out of the water supply hole. After the air is expelled, the water flows evenly into the water tank through the gap between the baffle 2 and the outlet pipe. At this time, there is no air in the chamber, avoiding the noise generated by the vibration of water flow and air. When installing the toilet, the inlet pipe 3 needs to be connected to the water supply interface. The pipe spacing varies greatly in different installation scenarios. The telescopic adjustable structure of the inlet pipe 3 can adapt to different lengths. To prevent leaks or stress damage caused by rigid bending of the pipe, a sealing triangular gasket 31 is located between the bottom interface of the inlet valve body 1 and the nut of the inlet pipe 3. The right-angled side of the sealing triangular gasket 31 corresponds to the right-angled surface of the interface, and the hypotenuse faces the nut. Through this structure, a spiral structure can be set on the outer wall of the inlet pipe 3 and the inner wall of the outlet pipe to guide the water flow spirally downward, so that the water flow adheres to the pipe wall and forms a spiral falling posture, slowing down the water flow speed, avoiding collisions between water and air and the pipe wall, reducing pipe vibration, and thus reducing noise. When the float 41 in the middle of the slider 4 rises or falls with the water level in the tank, the change in buoyancy drives the adjusting screw 42 to move, realizing the opening and closing of the inlet valve body 1. Through the above structure, the floating mechanism can be used as the inlet valve body 1. The "nerve center" of the toilet, its design precision directly affects the water-saving performance and reliability of the toilet. When the water level in the tank drops, the float 41 drops with the water level, driving the valve assembly upward through the adjusting screw 42. The water-stop pad disengages from the water inlet 5, and water flows in from the inlet valve body 1 through the water inlet 5, and then enters the water tank through the outlet pipe. When the water level rises to the set height, the float 41 floats up and pushes the valve assembly downward, sealing the water inlet 5 and cutting off the water flow. The opening edge of the water inlet 5 is smooth to prevent leakage caused by long-term wear of the water-stop pad. Through the above structure, the arc design of the edge of the water inlet 5 disperses the impact force of the water flow, guides the water flow to enter smoothly, reduces turbulence and air entrainment, and reduces water intake noise. When the water flows through the filter screen 6, the flow velocity is reduced by 30%, causing impurities to settle due to inertia.The above structure prevents the formation of a negative pressure zone in the inlet valve body 1 during water intake due to the filter screen structure, thus achieving anti-clogging and water pressure balance. EPDM rubber has high elasticity and anti-aging properties, and is not prone to hardening or cracking even after long-term contact with water, ensuring the sealing effect of the water inlet 5. Stainless steel or electroplating processes prevent scale buildup and corrosion, preventing leaks or increased noise due to component damage.
