[0002] The existing washing machine water inlet device generally connects the faucet to the washing machine's water inlet through an inlet pipe to achieve water intake;

[0003] Existing washing machine water inlet hoses are connected to faucets via quick-connect couplings. During use, if the water pressure is too high or the connection between the inlet hose and the faucet is not secure, the inlet hose is prone to bursting or detaching, causing water to splash everywhere. This is especially problematic for unattended automatic washing machines, resulting in significant water waste. Furthermore, when the quick-connect coupling is plugged into the faucet, the presence of the inlet hose connection affects the faucet's usability when the user needs to use it for water or other purposes. Therefore, we have proposed a new washing machine water inlet hose connection device to address these issues. Utility Model Content

Detailed Implementation

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown:

[0024] A connecting device for a washing machine water inlet pipe includes a connecting sleeve 103 that can be connected to a faucet, wherein the connecting sleeve 103 has a threaded groove inside, and an annular disc is fixed inside the connecting sleeve 103, and a rubber ring is mounted on the annular disc.

[0025] The snap-fit ​​connector 101 can be connected to the connecting sleeve 103. The outer surface of the connecting sleeve 103 is fixedly installed with an annular locking groove 104. The ball of the snap-fit ​​connector 101 can be snapped into the annular locking groove 104 to realize the connection and locking of the connecting sleeve 103 and the snap-fit ​​connector 101.

[0026] The connecting pipe 102 is fixedly installed at one end of the snap-fit ​​connector 101;

[0027] Leakage prevention mechanism 2, installed inside the connecting sleeve 103, automatically seals the faucet when the snap-fit ​​connector 101 is disengaged. Leakage prevention mechanism 2 includes a fixed plate 201 fixedly installed inside the connecting sleeve 103 and multiple sets of first drain holes 202 formed on the surface of the fixed plate 201. A guide rod 203 is slidably mounted on the fixed plate 201, a sealing plate 205 is fixedly attached to the surface of the guide rod 203, and a spring 204 is wound around the surface of the guide rod 203. Both ends of the spring 204 are fixedly connected to the sealing plate 205 and the fixed plate 201, respectively. A drain outlet 206 is formed at one end of the connecting sleeve 103 near the sealing plate 205. A connecting plate 207 is located below the sealing plate 205. The connecting plate 207 is fixed to one end of the guide rod 203. A second drain hole 208 is provided at the center of the surface of the connecting plate 207. A movable hole adapted to the guide rod 203 is provided on the fixed plate 201. The guide rod 203 can slide in the movable hole provided in the fixed plate 201. The diameter of the drain outlet 206 is smaller than the diameter of the sealing plate 205. The diameter of the connecting plate 207 is larger than the diameter of the drain outlet 206. The inside of the connecting sleeve 103 is a frustoconical cavity located at the position of the sealing plate 205. The diameter of the water supply hole provided in the snap-fit ​​connector 101 is smaller than the diameter of the connecting plate 207. The multiple sets of second drain holes 208 provided in the connecting plate 207 correspond to the delivery holes provided in the snap-fit ​​connector 101.

[0028] The connecting plate 207 has annular grooves on both the top and bottom, and a first sealing ring 209 and a second sealing ring 210 are respectively installed in the annular grooves on both sides.

[0029] The drainage connector 3 is disposed on the connecting sleeve 103. The drainage connector 3 includes a drainage auxiliary pipe 301 fixedly connected to the surface of the connecting sleeve 103 and a control valve 302 installed on the drainage auxiliary pipe 301.

[0030] In this implementation scheme: When the washing machine water inlet pipe connection device is in use, the connecting sleeve 103 has a threaded groove inside, and an annular plate is fixed above the fixing plate 201. A rubber ring is installed on the annular plate. When the threaded groove of the connecting sleeve 103 is connected with the threaded teeth on the faucet, by rotating the connecting sleeve 103, the drain end of the faucet is tightly fitted with the annular plate. The use of the rubber ring further enhances the sealing between the annular plate and the faucet, effectively preventing leakage between the connecting sleeve 103 and the faucet.

[0031] Next, the ball bearings of the snap-fit ​​connector 101 are snapped into the annular locking groove 104 on the surface of the connecting sleeve 103, thereby achieving a secure connection and locking between the snap-fit ​​connector 101 and the connecting sleeve 103.

[0032] When the snap-fit ​​connector 101 is inserted into the connecting sleeve 103, the bottom of the inner cavity of the snap-fit ​​connector 101 presses against the connecting plate 207, driving the connecting plate 207 to slide the guide rod 203 on the fixed plate 201. During this process, the upward movement of the guide rod 203 simultaneously drives the sealing plate 205 to move upward until the connecting plate 207 is in contact with the bottom of the connecting sleeve 103. At the same time, the bottom of the connecting plate 207 is also in contact with the bottom of the inner cavity of the snap-fit ​​connector 101. The connecting plate 207 is equipped with a first sealing ring 209 and a second sealing ring 210 on both sides. These two sealing rings are fixed on the connecting plate 207. Through their sealing effect, the sealing performance between the snap-fit ​​connector 101 and the connecting sleeve 103 is further enhanced.

[0033] As the guide rod 203 moves upward, the sealing plate 205 also moves upward synchronously, which causes the spring 204 to be compressed. Inside the connecting sleeve 103, a frustum-shaped cavity is formed at the position of the sealing plate 205. The upward movement of the sealing plate 205 releases the blockage of the drain outlet 206, and the space of the frustum-shaped cavity increases accordingly, allowing water to flow out smoothly through the gap between the frustum-shaped cavity of the connecting sleeve 103 and the sealing plate 205.

[0034] When the faucet valve is turned on, water flows out of the faucet and into the connecting sleeve 103; the water then enters the frustum cavity of the connecting sleeve 103 through the first drain hole 202; here, the water flows out through the gap between the frustum cavity of the connecting sleeve 103 and the sealing plate 205, advances along the drain outlet 206, and is discharged through the second drain hole 208 of the connecting plate 207; afterwards, the water flow is delivered to the snap-fit ​​connector 101 and discharged through the connecting pipe 102, and finally enters the cavity of the washing machine;

[0035] If the snap-fit ​​connector 101 falls off, the pressure on the connecting plate 207 will be released. At this time, the spring 204, which is in a compressed state, will rebound quickly, driving the sealing plate 205 to move down. The downward movement of the sealing plate 205, combined with the impact of water, can quickly seal the drain outlet 206 of the connecting sleeve 103, thereby avoiding a large amount of water leakage caused by the snap-fit ​​connector 101 falling off.

[0036] When the snap-fit ​​connector 101 is inserted into the connecting sleeve 103 to deliver water into the washing machine, the blockage of the drain auxiliary pipe 301 can be released by turning the control valve 302. In this way, some of the water discharged from the faucet can be discharged through the drain auxiliary pipe 301 for other water uses.

[0037] This solution, through the cooperation of the connecting sleeve 103 and the anti-leakage mechanism 2, can automatically seal the faucet when the snap-fit ​​connector 101 is detached, effectively preventing water resources from being wasted due to the connector detachment. At the same time, when the snap-fit ​​connector 101 and the connecting sleeve 103 are inserted into the faucet, the user can still use the faucet normally for water intake or other purposes, improving the effectiveness of the structure and meeting the needs of actual use.

[0038] Meanwhile, the snap-fit ​​connector 101 is not described in detail in this specification. This content belongs to the prior art known to those skilled in the art. For details, please refer to the water inlet pipe interface disclosed in document CN207276999U. The specific structure and function will not be described in detail.

[0039] The working principle and usage process of this utility model are as follows: In use, the connecting sleeve 103 has a threaded groove inside and is rotated to connect to the faucet. Next, the ball bearing of the snap-fit ​​connector 101 is inserted into the annular locking groove 104 on the surface of the connecting sleeve 103. When the snap-fit ​​connector 101 is inserted into the connecting sleeve 103, the bottom of the inner cavity of the snap-fit ​​connector 101 presses against the connecting plate 207, driving the connecting plate 207 to move the guide rod 203 on the fixed plate 201. During this process, the upward movement of the guide rod 203 simultaneously moves the sealing plate. 205 moves upward until the connecting plate 207 is in contact with the bottom of the connecting sleeve 103. At the same time, the bottom of the connecting plate 207 is also in contact with the bottom of the inner cavity of the snap-fit ​​connector 101. As the guide rod 203 moves upward, the sealing plate 205 also moves upward in sync. This causes the spring 204 to be compressed. Inside the connecting sleeve 103, a frustum-shaped cavity is formed at the position of the sealing plate 205. The upward movement of the sealing plate 205 releases the blockage of the drain outlet 206. The space of the frustum-shaped cavity increases accordingly, allowing water to flow out smoothly through the gap between the frustum-shaped cavity of the connecting sleeve 103 and the sealing plate 205.

[0040] When the faucet valve is turned on, water flows out of the faucet and into the connecting sleeve 103; the water then enters the frustoconical cavity of the connecting sleeve 103 through the first drain hole 202; here, the water flows out through the gap between the frustoconical cavity of the connecting sleeve 103 and the sealing plate 205, advances along the drain outlet 206, and is discharged through the second drain hole 208 of the connecting plate 207; afterwards, the water flow is transported to the snap-fit ​​connector 101 and discharged through the connecting pipe 102, finally entering the washing machine cavity; if the snap-fit ​​connector 101 falls off, the pressure on the connecting plate 207 will... When released, the compressed spring 204 will quickly rebound, driving the sealing plate 205 to move downward. The downward movement of the sealing plate 205, combined with the impact of water, can quickly seal the drain outlet 206 of the connecting sleeve 103, thereby preventing a large amount of water leakage caused by the snap-fit ​​connector 101 coming off. When the snap-fit ​​connector 101 is inserted into the connecting sleeve 103 to deliver water to the washing machine, the blockage of the drain auxiliary pipe 301 can be released by turning the control valve 302. In this way, some water discharged from the faucet can be discharged through the drain auxiliary pipe 301 for other water uses.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
