Description

Technical Field

[0001] This utility model relates to the field of bathroom valve equipment technology, and more specifically to a water valve core with delayed automatic shut-off. Background Technology

[0002] Currently, most time-delay water valves on the market are either magnetically controlled push-button type or electrically induction type. These valves have the following drawbacks: due to the diverse application scenarios, the water supply time of commercially available time-delay valves is short and fixed, failing to meet various water usage needs in a single operation. This necessitates multiple operations or repeated pressing, adding inconvenience to users and affecting the valve's lifespan. Therefore, we propose a time-delay automatic shut-off water valve core. By adding a control switch to the valve core, the water output time can be flexibly controlled to meet different water demand, improving the practicality of the time-delay water valve.

[0003] To achieve the function of automatically closing a water valve after a delay, applicable to scenarios such as toilets and bathroom faucets, Chinese patent (authorization announcement number: CN111609196A) discloses a push-button flush valve. This invention includes a valve body and a valve cover. The valve body has a partition dividing the interior into an inlet chamber and an outlet chamber, with mounting holes on the partition. The valve cover has a push-button delay device, which includes a pressing part and a delay part, connected by a pressure rod penetrating the valve cover. The pressing part includes a pressure cap connected to one end of the pressure rod and return springs at both ends abutting between the pressure cap and the valve cover. One end of the delay part is located in the outlet chamber, and the other end is located in the inlet chamber through the mounting hole. The delay part includes a delay barrel, an outlet cover, and a sealing head, with the delay barrel extending into the mounting hole. Furthermore, the edge of the delay tank opening abuts against the partition plate. The side wall of the delay tank located near the opening of the delay tank has a water inlet hole. One side of the water outlet cover abuts against the opening of the delay tank, and the other side of the water outlet cover abuts against the valve cover. The center of the water outlet cover has a water outlet hole for the insertion of the pressure rod. The side of the water outlet cover near the valve cover has a water outlet groove that extends from the water outlet hole to the outer wall of the water outlet cover. The water sealing head slides inside the delay tank and is fixed to the end of the pressure rod away from the pressing part. The side of the water sealing head near the pressure rod has a water sealing ring that abuts against the water outlet hole. The side of the water sealing head away from the pressure rod has a delay sealing ring that abuts against the inner wall of the delay tank. The side of the water sealing head away from the pressure rod has a return hole that connects to the outer side of the water sealing head between the water sealing ring and the delay sealing ring. This invention has the effect of delayed closing of the flush valve.

[0004] The solution still has some shortcomings in application. Since the delayed water valve is used in a wide range of scenarios, it needs to be able to adjust the water output according to different scenarios. Otherwise, it is easy to have to press the button multiple times to get continuous water output, which affects the use and causes inconvenience to users. At the same time, pressing the button multiple times will also shorten the service life of the delayed water valve. Therefore, it is necessary to improve the structure of the delayed water valve so that it can adjust the delayed closing time as needed, thereby improving its practicality and applicability. Utility Model Content

[0005] This utility model discloses a water valve core with delayed automatic shut-off, the main purpose of which is to overcome the above-mentioned shortcomings and disadvantages of the existing technology:

[0006] The technical solution adopted in this utility model is as follows:

[0007] A water valve core with delayed automatic shut-off includes a water valve body. An inlet pipe, a pressing device, a control housing, and a water outlet are respectively screwed onto the left, right, bottom, and top sides of the water valve body. A copper housing is built into the water valve body, and a valve core is built into the copper housing.

When engaged, water continues to flow from the outlet, the valve core remains in an upward-facing position, and the spring at the top of the valve core is compressed and stores energy. Finally, upon activation of the control switch, the valve core is pressed downwards by the spring, blocking the outlet again through the sealing ring, achieving automatic closure. This design enables a delayed-closing function, and the water flow time can be adjusted by regulating the activation time of the control switch. This invention boasts a novel structure and ingenious design, achieving both delayed automatic closure and adjustable water flow time, making it highly practical and suitable for widespread adoption.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 5As shown, a water valve core with delayed automatic shut-off includes a water valve body 1. The water valve body 1 has an inlet pipe 2, a pressing device 3, a control housing 4, and an outlet 5 respectively screwed onto its left side, right side, bottom, and top. The water valve body 1 has a copper housing 11 inside, and a valve core 6 is built into the copper housing 11. One side of the valve core 6 is connected to the pressing device 3, and a sealing ring 7 is provided at its lower part. The sealing ring 7 is movably fitted onto the outlet 5 through the pressing device 3. An abutment ring 8 is installed on the upper outer wall of the valve core 6, and a spring 9 is installed on its top. The top of the spring 9 is connected to the control housing 4. A control switch 10 is symmetrically installed on the inner wall of the control housing 4, and the control switch 10 movably abuts against the abutment ring 8.

[0022] Furthermore, the copper housing 11 is provided with a left opening 111, a right opening 112, an upper opening 113 and a lower opening 114, respectively. The left opening 111, the right opening 112 and the upper opening 113 are respectively provided with the water inlet pipe 2, the pressing device and the control housing 4.

[0023] Furthermore, the pressing device 3 includes a sleeve 31 and a lifting rod 32. The lifting rod 32 is built into the sleeve 31. One end of the lifting rod 32 is connected to the side of the valve core 6, and the other end extends outward and is provided with a pressing plate 33. A bolt 34 is provided at the front of the lifting rod 32. The bolt 34 is rotatably connected to the inner wall of the sleeve 31. The lifting rod 32 can drive the valve core 6 to be pushed upward through the pressing plate 33 and the bolt 34.

[0024] Furthermore, the water inlet pipe 2 has a cross-shaped structure, and a regulating valve 21 is provided in the middle section of the cross-shaped structure.

[0025] Furthermore, a lithium battery 41 and a control panel 42 are installed on the top of the control housing 4. The lithium battery 41 is electrically connected to the control switch 10, and the control panel 42 is controlled by the control switch 10.

[0027] [Example]

[0028] First, the opening time of the control switch 10 is set via the control panel 42. At this time, the sealing ring 7 is fitted onto the outlet 5. Next, the pressing plate 33 is pressed down, and one end of the lifting rod 32 is pressed down. Through the action of the bolt 34, the other end is lifted up. The lifting rod 32 lifts up, causing the valve core 6 to rise. At this time, the sealing ring 7 disengages from the outlet 5, and water enters from the inlet pipe 2 and exits from the outlet 5. At the same time, the limit ring 8 on the upper part of the valve core 6 is engaged with the control switch 10 and will not descend. The spring 9 on the top of the valve core 6 is compressed and stores energy. Finally, when the control switch 10 reaches the set time, it starts to disengage from the limit ring 8. The valve core 6 rebounds and descends through the spring 9. The sealing ring 7 at the lower part of the valve core 6 is tightened and sealed again with the outlet 5, and the water flow stops. Through this setting, the water valve can be automatically closed with a delay, and the closing time can also be set, which is very convenient and practical.

[0029] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0030] This invention firstly features a valve core housed within a copper casing. A sealing ring is located at the lower part of the valve core, and a lifting rod is positioned on one side. The lifting rod, via a pressing plate, pushes the valve core upwards, disengaging the sealing ring from the outlet and allowing water to flow.
