Description

Technical Field

[0001] This utility model relates to the field of washing machine stop valve technology, and in particular to a washing machine stop valve that can be quickly pulled out. Background Technology

[0002] The washing machine stop valve is a crucial component of the washing machine's water inlet system. It is typically installed between the water supply pipe and the washing machine hose to control water flow and automatically stop water leakage in case the hose accidentally detaches. A typical washing machine stop valve includes a body, valve core, handwheel, connector, and stop valve core. The body has an inlet and outlet chamber. The valve core is installed between these chambers to regulate water flow. The handwheel drives the valve core. The connector is located on the underside of the body and communicates with the outlet chamber. The stop valve core is located within the outlet channel of the connector. When connected to the washing machine hose connector, the stop valve core is lifted to allow water flow; when the hose detaches, it lowers to seal the outlet channel, achieving automatic water stop.

[0003] To improve the stability and anti-detachment performance of washing machine hose connections, some existing washing machine hose connectors incorporate an internal connecting sleeve. This sleeve fits tightly against the side wall of the sealing core during connection, enhancing the clamping force between the two. However, this design presents significant inconvenience when the hose connector needs to be removed: after the locking mechanism of the hose connector is unlocked, due to the large contact area and friction between the connecting sleeve and the sealing core, users often need to apply considerable pulling force or repeatedly shake the connector to remove it. This operation is not only laborious and time-consuming, but may also damage the sealing core, sealing ring, or hose connector due to improper force, affecting the sealing performance and lifespan of the faucet.

[0004] Therefore, existing washing machine stop valves fall short in balancing connection reliability and ease of removal, especially for hose connectors with tightly fitting connecting sleeves, where the difficulty of removal urgently needs to be addressed. It is necessary to improve the structure of the stop valve to achieve both reliable connection and quick, effortless removal of the hose connector. Utility Model Content

[0005] This invention proposes a quick-release washing machine stop valve, which solves the aforementioned problems existing in the use of existing technologies.

[0006] The technical solution of this utility model is implemented as follows: A quick-release washing machine stop valve includes a body, a valve core, a handwheel, a connector, and a stop valve core. The body has an inlet chamber located at the rear and an outlet chamber located at the bottom. The valve core is installed in the body and located between the inlet and outlet chambers. The handwheel is connected to the valve core. The connector is connected to the bottom of the body and communicates with the outlet chamber. The connector has an outlet channel for assembling the stop valve core. A rotating seat is fixedly installed between the connector and the body. The rotating seat has a through-hole in the middle for the stop valve core to pass through. Several downward inclined protrusions are integrally formed on the outer periphery of the rotating seat. The upper circumference of the stop valve core has an upper inclined protrusion corresponding to the number of inclined protrusions. A locking slot is opened at the lower end of the stop valve core.

[0007] Preferably, the upper side of the connector includes an internal thread section for threaded connection to the body, the connector has a limiting step on the lower side of the internal thread section, a sealing support surface located on the upper side of the water outlet channel is opened on the inner side of the limiting step, and a sealing ring is installed on the water-stop core located on the upper side of the sealing support surface, the sealing ring being located below the upper inclined protrusion.

[0008] Preferably, the outer side of the rotating seat is integrally formed with a mounting ring, which is clamped between the limiting step and the lower end of the body.

[0009] Preferably, sealing gaskets are fitted to both the upper and lower sides of the mounting ring.

[0010] Preferably, the upper side of the water-stopping core is provided with a compression spring, the main body has an upper spring slot at the top of the water outlet cavity for the upper end of the compression spring to be inserted, the water-stopping core has a lower spring slot for the lower end of the compression spring to be inserted, and the water-stopping core is also integrally formed with a positioning post sleeved inside the spring.

[0011] Preferably, there are three lower inclined surface protrusions and three upper inclined surface protrusions. Each lower inclined surface protrusion has a lower inclined surface that is inclined from bottom to top in a counterclockwise direction, and each upper inclined surface protrusion has an upper inclined surface corresponding to the lower inclined surface.

[0012] Preferably, the water-stop core has a downward-through outlet on the lower side of the sealing ring, and a water passage communicating with the outlet is provided on the side wall of the water-stop core.

[0013] Preferably, the main body is equipped with a check valve in the water inlet chamber.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] 1. By fixing a rotating seat with a downward-sloping protrusion between the main body and the connector, and setting an upper-sloping protrusion and a locking device on the water-stop core to cooperate with it, the "rotation" action is converted into an "axial lifting" action. When it is necessary to pull out the washing machine hose connector, the user only needs to unlock and then rotate the hose connector. Rotating the hose connector drives the water-stop core to rotate through the locking device. Through the cooperation between the upper-sloping protrusion of the water-stop core and the upper and lower-sloping protrusions of the rotating seat, the water-stop core can be driven to move automatically upward relative to the connector a certain distance, thereby partially disengaging it from the connecting sleeve of the hose connector, significantly reducing the contact area and static friction between the two. This makes the subsequent pull-out operation less strenuous, faster, and easier, effectively solving the problem of "difficulty in pulling out" caused by the tight fit of the connecting sleeve, and greatly improving the user experience and ease of operation.

[0016] 2. The mounting ring is clamped between the connector limiting step and the lower end of the body, and sealing gaskets are added on the upper and lower sides of the mounting ring. The structure is stable and reliable, and has good sealing performance. Attached Figure Description

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example:

[0027] like Figures 1-6 As shown, this utility model discloses a washing machine water stop faucet that can be quickly pulled out. Its core purpose is to solve the problem of difficulty in pulling out the existing washing machine hose connector 9 due to the connection sleeve 93 that tightly fits the water stop core 5.

[0028] The washing machine stop valve mainly includes a body 1, a valve core 2, a handwheel 3, a connector 4, and a stop valve core 5. The body 1 is usually made of metal or high-strength plastic, and has an inlet chamber 11 located at the rear and an outlet chamber 12 located at the bottom. The inlet chamber 11 is used to connect to the external water supply pipe, while the outlet chamber 12 communicates with the connector 4 connected to the bottom of the body 1. The valve core 2 is installed inside the body 1 and located between the inlet chamber 11 and the outlet chamber 12 to control the flow and flow rate of water. The handwheel 3 is connected to the front end of the valve core 2 for manual operation by the user. Preferably, a check valve 8 can also be installed in the inlet chamber 11 of the body 1 to prevent backflow of water and protect the water supply pipe. Both the valve core 2 and the check valve 8 are existing products.

[0029] The specific structure of the connector 4 connected to the lower side of the body 1 is as follows: The upper side of the connector 4 includes an internal thread section 42 for threaded connection to the body 1. The connector 4 is screwed to the lower outlet of the body 1 through its upper internal thread section 42 and remains connected to the water outlet cavity 12. The connector 4 has a through-flow water outlet channel 41 inside, which is used to assemble the water-stop core 5. Below the internal thread section 42 of the connector 4, there is a radially inwardly protruding limiting step 43, and a sealing abutment surface 44 located above the water outlet channel 41 is formed on the inner side of the limiting step 43.

[0030] A rotating seat 6 is fixedly installed between the connector 4 and the body 1. The rotating seat 6 is an annular component with a mounting ring 64 integrally formed on its outer circumference. The mounting ring 64 is clamped between the limiting step 43 and the lower end of the body 1. During assembly, the rotating seat 6 is first placed on top of the connector 4, and then the internal thread section 42 of the connector 4 is screwed into the body 1, so that the mounting ring 64 of the rotating seat 6 is tightly clamped between the limiting step 43 of the connector 4 and the lower end face of the body 1. To ensure the sealing of this connection, a rubber sealing gasket 72 can be placed on the upper and lower sides of the mounting ring 64 respectively.

[0031] The rotating seat 6 has a through-hole 61 in the middle for the water-stopping core 5 to pass through. On the outer periphery of the through-hole 61, the rotating seat 6 is integrally formed with several upwardly protruding downward-sloping protrusions 62. In a preferred embodiment, three downward-sloping protrusions 62 are provided and evenly distributed along the circumference. Each downward-sloping protrusion 62 has a downward-sloping surface 63 that slopes counterclockwise from bottom to top.

[0032] The water-stopping core 5 is a vertically movable cylindrical component. Its upper part passes through the through-hole 61 of the rotating seat 6, and its lower part is fitted into the water outlet channel 41 of the connector 4 and exits the connector 4. On the upper circumference of the water-stopping core 5, there are integrally formed upper inclined protrusions 51 corresponding to the number and position of the lower inclined protrusions 62. Similarly, there are three upper inclined protrusions 51, each with an upper inclined surface 52 that can be attached to and slide relative to the lower inclined surface 63.

[0033] In addition, a bayonet 53 is provided at the lower end of the water-stop core 5. The bayonet 53 is used to cooperate with the integrally formed clamp 94 inside the washing machine hose connector 9, so that the washing machine hose connector 9 can drive the water-stop core 5 to rotate together when it rotates.

[0034] To achieve automatic water-stopping function, a sealing ring 71 is installed on the water-stopping core 5, located below the upper inclined protrusion 51. In normal water flow (i.e., when the connector 4 of this invention is inserted into the washing machine hose connector 9 and locked), the sealing ring 71 is positioned above the sealing support surface 44 as the water-stopping core 5 is pushed by the hose connector 9, allowing water to flow through. Furthermore, a compression spring 73 is provided above the water-stopping core 5. Specifically, the main body 1 has an upper spring slot 13 at the top of the water outlet chamber 12 and a lower spring slot 54 on the water-stopping core 5, with both ends of the compression spring 73 respectively inserted into these two slots. To further improve the stability of the spring setting, an upwardly extending positioning post 55 is integrally formed on the water-stopping core 5, which is fitted inside the compression spring 73. The compression spring 73 always applies a downward thrust to the water-stopping core 5.

[0035] Regarding the water flow channel, the water-stopping core 5 has at least one water outlet 57 on its side wall below the sealing ring 71. The water outlet 57 is connected to the water outlet 56 that extends downward through the interior of the water-stopping core 5, thus forming a water flow passage.

[0036] Washing machine hose connector 9 connected to this application, as shown in the example Figure 5 As shown, it includes an outer sleeve 91 for being fitted onto the outside of the connector 4, a locking mechanism 92 for being locked onto the locking slot 45 on the outside of the connector 4 (the locking mechanism 92 is prior art and has been widely used in existing products, so it will not be described in detail here), a connecting sleeve 93 for being fitted onto the outside of the water-stop core 5, and a clip 94 for being inserted into the slot 53.

[0037] When connecting to a washing machine, the connector 4 of this invention is inserted into the washing machine hose connector 9. The retainer 94 inside the hose connector 9 engages with the retainer 53 at the lower end of the water-stop core 5, pushing the water-stop core 5 upward against the elastic force of the compression spring 73. The upward movement of the water-stop core 5 causes the sealing ring 71 to move away from the sealing abutment surface 44 of the connector 4. At this time, as... Figure 5 As shown, water can flow from the water outlet 12 of the main body 1 through the through 61 of the rotating seat 6, the water inlet 57 on the side wall of the water-stopping core 5, and the internal water outlet 56 into the washing machine hose.

[0038] If the water pressure is too high during washing machine operation or the locking mechanism 92 fails, causing the hose connector 9 to accidentally detach, the spring force of the compression spring 73 will quickly push the water-stop core 5 downward. The downward movement of the water-stop core 5 causes the sealing ring 71 on it to press tightly against the sealing support surface 44 of the connector 4, thereby immediately sealing the water outlet channel 41. Figure 2 As shown, it achieves automatic water stoppage to prevent water leakage accidents.

[0039] When it is necessary to actively disconnect the washing machine, first release the locking mechanism 92 of the hose connector 9. At this time, since the connecting sleeve 93 inside the hose connector 9 is still tightly fitted to the outer wall of the water-stop core 5, it is difficult to pull it out directly. At this time, the user only needs to hold the hose connector 9 and rotate it counterclockwise. The rotation action is transmitted to the water-stop core 5 through the cooperation of the bayonet 53 and the locking piece 94, so that it rotates synchronously. The upper inclined surface protrusion 51 on the upper side of the water-stop core 5 rotates accordingly, and the upper inclined surface 52 on it will slide along the lower inclined surface 63 of the lower inclined surface protrusion 62 of the rotating seat 6. Since the lower inclined surface 63 is inclined from bottom to top in a counterclockwise direction, this rotational motion is converted into an upward axial displacement by the inclined surface, thereby driving the water-stop core 5 to move upward a small distance relative to the body 1 and the connector 4 (that is, to continue to move the water-stop core 5 upward from the state of being pushed upward by the hose connector 9 under normal connection). Figure 6 As shown. This small displacement is sufficient to allow the lower part of the water-stop core 5 to partially "disengage" from the connecting sleeve 93 of the hose connector 9, thereby greatly reducing the contact area and friction between the two. While rotating, the user only needs to apply a small downward pulling force to easily and quickly pull the hose connector 9 completely out.

[0040] In summary, this utility model innovatively introduces a rotating seat with a beveled protrusion and a matching water-stopping core into the traditional water-stopping faucet structure, cleverly converting the rotational motion into an axial lifting motion. Without affecting the connection sealing and automatic water-stopping function, it perfectly solves the problem of difficult extraction of hose connectors in specific structures, making operation labor-saving and quick, and significantly improving the user experience.

[0041] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
