Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pipe connector technology, and in particular to a vibration-proof washing machine inlet valve. Background Technology
[0002] In the prior art, the water inlet valve of a washing machine is generally installed on the upper rear side of the control panel. The water inlet connector on the water inlet valve protrudes from the rear or upper side of the control panel. During operation, the washing machine will vibrate. Existing connection methods, such as clamp connection or simple threaded connection, are prone to causing the water pipe to fall off due to vibration, resulting in water leakage or the washing machine failing to work properly.
[0003] Chinese patent CN107354681A discloses a water inlet valve for a washing machine, including a valve body disposed on the washing machine body; a connector disposed on the valve body, with a water pipe corresponding to the connector; the connector and the water pipe are connected by a snap-fit structure; the snap-fit structure includes a first snap-fit unit formed on the connector; the first snap-fit unit includes a slot structure for quick connection between the connector and the water pipe, the slot structure being disposed in the circumferential direction of the connector; the first snap-fit unit also includes a sealing groove for installing a sealing ring, the sealing groove being disposed in the circumferential direction of the connector.
[0004] Although the above-mentioned technical solutions involve a snap-fit connection method to achieve quick disassembly and assembly, their vibration resistance is insufficient, which can easily lead to loosening or breakage of the connection, affecting the service life of the washing machine. At the same time, loosening of the connection can also cause gaps between the water inlet valve and the water supply pipe, which can easily cause water leakage, affecting the service life of the washing machine and the user experience. Therefore, the present invention solves the shortcomings of the above-mentioned technical problems. Utility Model Content
[0005] Based on the aforementioned technical problems, this utility model proposes a vibration-proof washing machine inlet valve.
[0006] This utility model proposes a vibration-proof washing machine water inlet valve, including a valve body. A water inlet pipe is fixedly connected to the upper surface of the valve body, and a connecting pipe is fixedly connected to the upper surface of the water inlet pipe. An anti-detachment connecting mechanism is provided inside the connecting pipe. The anti-detachment connecting mechanism includes connecting clips. Two connecting clips are symmetrically arranged inside the connecting pipe. The connecting clips clamp the pipe extending into the connecting pipe to prevent it from falling off.
[0007] Preferably, the anti-detachment connection mechanism further includes a water supply pipe that is slidably inserted into the inside of the connecting pipe, wherein the diameter of the connecting pipe is larger than the diameter of the water inlet pipe.
[0008] Through the above technical solution, the water supply pipe is connected to the water inlet valve, thereby controlling the water intake of the washing machine. In order to design the inserted water supply pipe to prevent vibration, the water supply pipe is inserted into the connecting pipe and then clamped by the connecting clamp inside the connecting pipe to achieve vibration prevention and prevent it from falling off.
[0009] Preferably, the anti-detachment connection mechanism further includes a tapered tube fixedly connected to the lower surface of the water supply pipe, and an annular groove is provided on the outer surface of the connection between the tapered tube and the water supply pipe, and the outer surface of the connecting clamp is slidably engaged with the inner surface of the annular groove.
[0010] In order to connect the water supply pipe to the inlet valve, the tapered tube is inserted into the connecting block along with the water supply pipe. The end face of the tapered tube then spreads the two symmetrical connecting clips until the connecting clips are inserted into the annular groove, which prevents the water supply pipe from falling off.
[0011] Preferably, the connecting clip has an S-shaped design and is made of polyurethane.
[0012] Through the above technical solution, in order to achieve the deformation of the connecting clamp, the inner surface of its S-shaped design allows the end face of the tapered tube to slide over it, and then the tapered tube can open the connecting clamp made of polyurethane material. After the annular groove moves to the bottom of the connecting clamp, the connecting clamp resets, so that the connecting clamp clamps the connection between the tapered tube and the water pipe.
[0013] Preferably, the connection anti-detachment mechanism further includes a rotating bearing fixedly connected to the inner wall of the connecting pipe connection port, a support ring fixedly connected to the lower surface of the inner ring of the rotating bearing, a connecting ring with a shock-absorbing spring fixedly sleeved on the outer surface of the support ring, and the lower surface of the connecting ring fixedly connected to the upper surface of the connecting clamp.
[0014] With the above technical solution, in order to prevent the connecting pipe from vibrating due to collision and causing the connecting clamp to fall off, when the connecting pipe vibrates, the vibration energy will be transmitted to the connecting ring through the support ring. The damping spring can effectively absorb and dissipate this vibration energy, converting it into the elastic potential energy of the spring and the heat energy generated by internal friction, thereby significantly reducing the vibration amplitude and frequency transmitted to the connecting clamp. This makes the connecting clamp maintain a more stable state in the vibration environment.
[0015] Preferably, the upper surface of the connecting pipe is fixedly connected to a threaded pipe, and the upper outer surface of the water supply pipe is fixedly fitted with an L-shaped threaded sleeve, the inner surface of the threaded sleeve being threadedly connected to the outer surface of the threaded pipe.
[0016] Through the above technical solution, in order to achieve a fixed connection between the water supply pipe and the connecting pipe, the water supply pipe is rotated so that the threaded sleeve is threaded onto the outer surface of the threaded pipe, thereby fixing the water supply pipe. At the same time, the L-shaped threaded sleeve achieves a seal between the two, and the setting of the rotating bearing can realize the rotation conditions of the connecting clamp and the water supply pipe.
[0017] The beneficial effects of this utility model are as follows:
[0018] 1. By setting up an anti-detachment connection mechanism, including a connecting clip and a tapered tube, the water supply pipe is effectively prevented from falling off due to vibration during the operation of the washing machine, avoiding problems such as water leakage or the washing machine malfunctioning. The S-shaped design and polyurethane material of the connecting clip allow it to adapt to the opening and repositioning of the tapered tube, ensuring a firm connection.
[0019] 2. By setting up rotating bearings, support rings and connecting rings, a shock absorption mechanism is formed, which effectively absorbs and dissipates vibration energy, reduces the vibration amplitude and frequency transmitted to the connecting clamp, and prevents the connecting clamp from loosening or falling off due to vibration.
[0020] 3. By using threaded sleeves and threaded pipes, a fixed connection between the water supply pipe and the connecting pipe is achieved. At the same time, the L-shaped threaded sleeve ensures the sealing of the connection, prevents water leakage, and improves the user experience. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Reference Figures 1-5 A vibration-proof washing machine inlet valve includes a valve body 1. A water inlet pipe 2 is fixedly connected to the upper surface of the valve body 1. A connecting pipe 3 is fixedly connected to the upper surface of the water inlet pipe 2. An anti-detachment connecting mechanism is provided inside the connecting pipe 3. The anti-detachment connecting mechanism includes a connecting clip 4. Two connecting clips 4 are symmetrically arranged inside the connecting pipe 3. The connecting clips 4 clamp the pipe that extends into the connecting pipe 3 to prevent it from falling off.
[0029] The water supply pipe 13 is connected to the water inlet valve to control the water intake of the washing machine. In order to design the water supply pipe 13 to prevent vibration, the anti-detachment connection mechanism also includes the water supply pipe 13 that is slidably inserted into the connecting pipe 3. The diameter of the connecting pipe 3 is larger than the diameter of the water inlet pipe 2. After the water supply pipe 13 is inserted into the connecting pipe 3, the connecting clamp 4 inside the connecting pipe 3 clamps the water supply pipe 13 to achieve anti-vibration and anti-detachment.
[0030] In order to connect the water supply pipe 13 to the pipe on the inlet valve, the anti-detachment connection mechanism also includes a tapered pipe 5 fixedly connected to the lower surface of the water supply pipe 13. The outer surface of the tapered pipe 5 and the water supply pipe 13 is provided with an annular groove 6. The outer surface of the connecting clip 4 slides and engages with the inner surface of the annular groove 6. After the tapered pipe 5 and the water supply pipe 13 are inserted into the connecting block, the end face of the tapered pipe 5 will spread the two symmetrical connecting clips 4 until the connecting clips 4 are inserted into the annular groove 6, which can prevent the water supply pipe 13 from falling off.
[0031] In order to achieve the deformation of the connecting clip 4, the connecting clip 4 is designed in an S-shape and is made of polyurethane. The inner surface of the S-shaped design of the connecting clip 4 allows the end face of the tapered tube 5 to slide over it, and the tapered tube 5 can open the polyurethane connecting clip 4. When the annular groove 6 moves to the bottom of the connecting clip 4, the connecting clip 4 resets, so that the connecting clip 4 clamps the connection between the tapered tube 5 and the water pipe 13.
[0032] By setting up an anti-detachment connection mechanism, including a connecting clip 4 and a tapered tube 5, the water supply pipe 13 is effectively prevented from falling off due to vibration during the operation of the washing machine, thus avoiding problems such as water leakage or the washing machine malfunctioning. The S-shaped design and polyurethane material of the connecting clip 4 allow it to adapt to the opening and repositioning of the tapered tube 5, ensuring a firm connection.
[0033] To prevent the connecting pipe 3 from vibrating due to impact and causing the connecting clamp 4 to detach, the anti-detachment mechanism also includes a rotating bearing 7 fixedly connected to the inner wall of the connecting port of the connecting pipe 3. A support ring 8 is fixedly connected to the lower surface of the inner ring of the rotating bearing 7. A connecting ring 9 with a shock-absorbing spring 10 is fixedly sleeved on the outer surface of the support ring 8. The lower surface of the connecting ring 9 is fixedly connected to the upper surface of the connecting clamp 4. When the connecting pipe 3 vibrates, the vibration energy is transmitted to the connecting ring 9 through the support ring 8. The shock-absorbing spring 10 can effectively absorb and dissipate this vibration energy, converting it into the elastic potential energy of the spring and the heat energy generated by internal friction, thereby significantly reducing the vibration amplitude and frequency transmitted to the connecting clamp 4. This makes the connecting clamp 4 maintain a more stable state in the vibration environment.
[0034] By setting up a rotating bearing 7, a support ring 8, and a connecting ring 9, a shock absorption mechanism is formed, which effectively absorbs and dissipates vibration energy, reduces the vibration amplitude and frequency transmitted to the connecting clip 4, and prevents the connecting clip 4 from loosening or falling off due to vibration.
[0035] To achieve a fixed connection between the water supply pipe 13 and the connecting pipe 3, a threaded pipe 11 is fixedly connected to the upper surface of the connecting pipe 3. An L-shaped threaded sleeve 12 is fixedly fitted onto the upper outer surface of the water supply pipe 13. The inner surface of the threaded sleeve 12 is connected to the outer surface of the threaded pipe 11. By rotating the water supply pipe 13, the threaded sleeve 12 can be connected to the outer surface of the threaded pipe 11, thereby fixing the water supply pipe 13. At the same time, the L-shaped threaded sleeve 12 achieves a seal between the two. The rotating bearing 7 enables the connecting clamp 4 to rotate in conjunction with the water supply pipe 13.
[0036] The connection between the threaded sleeve 12 and the threaded pipe 11 is achieved by fixing the water supply pipe 13 and the connecting pipe 3. At the same time, the L-shaped threaded sleeve 12 ensures the sealing of the connection part, prevents water leakage, and improves the user experience.
[0037] Working principle: In a specific embodiment of this utility model, the water supply pipe 13 is inserted into the connecting pipe 3 until the end face of the tapered pipe 5 opens the connecting clamp 4. The water supply pipe 13 is then pushed to make the annular groove 6 on the tapered pipe 5 engage with the outer surface of the connecting clamp 4, thus achieving initial fixation. The L-shaped threaded sleeve 12 of the water supply pipe 13 is then threadedly connected to the threaded pipe 11 on the connecting pipe 3 to achieve fixation of the water supply pipe 13.
[0038] When the washing machine vibrates during operation, the vibration energy is transmitted through the support ring 8 to the shock-absorbing spring 10 on the connecting ring 9. The shock-absorbing spring 10 absorbs and dissipates the vibration energy, reducing the vibration amplitude and frequency transmitted to the connecting clip 4, and preventing the connecting clip 4 from loosening or falling off.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
