Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of faucet valves, in particular to a self-closing faucet valve. BACKGROUND

[0002] A faucet is a colloquial term for a water valve, which is used to control the size of the water flow and has the function of water saving. The update speed of faucets is very fast, from the old cast iron process to the plated knob type, and then to the stainless steel single temperature single control faucet, stainless steel double temperature double control faucet, and kitchen semi-automatic faucet. Now, more and more consumers choose faucets, and they will consider the material, function, shape, etc. from multiple aspects.

[0003] The common faucet valve on the market has some obvious defects in use, which affects the user experience and the rational use of water resources. First, the traditional faucet valve usually does not have a self-closing function and needs to be manually closed after use. In actual life, people often forget to close the faucet due to negligence, resulting in waste of water resources. For example, in public toilets, canteens and other places, if the user leaves in a hurry without closing the faucet, the water flow will continue to flow, causing a large amount of water resources to be lost; secondly, the existing faucet valve cannot flexibly adjust the closing speed. Different use scenarios may have different requirements for the closing speed of the water flow, for example, in some occasions where the water flow needs to be accurately controlled, fast closing may cause water to splash out, while slow closing may cause unnecessary waiting and waste.

[0041] Further: the staff only needs to push the pushing block 2205 upward to drive the clamping tooth 2203 upward to release the locking of the gear ring 2101, which is convenient for the staff to rotate the torsion block 1105 subsequently and also enables the torsion block 1105 to complete the adjustment of the elastic strength of the compression spring 1204 after the rotation to complete the positioning of the position of the cover 1102, thereby increasing the stability of the device during use. Embodiment three

[0042] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9And on the basis of Embodiment One and Embodiment Two, it is further obtained that the pressing mechanism 3 comprises a pressing assembly 31 and a pressing-down assembly 32, the pressing assembly 31 is arranged at the top of the faucet 4, and the pressing-down assembly 32 is arranged in the pressing assembly 31.

[0043] The pressing assembly 31 comprises a fixed cylinder two 3101, the fixed cylinder two 3101 is fixedly connected to the top of the faucet 4, a sealing plate 3102 is fixedly connected to the bottom of the inner ring of the fixed cylinder two 3101, a return spring 3103 is fixedly connected to the top of the sealing plate 3102, a pressing cap 3104 is fixedly connected to the top of the return spring 3103, the pressing-down assembly 32 comprises a pressing-down slide rod 3201, the pressing-down slide rod 3201 is fixedly connected to the inner top of the pressing cap 3104, the pressing-down slide rod 3201 is slidingly connected to the sealing plate 3102, an extension slide bar 3202 is fixedly connected to the outer ring of the pressing-down slide rod 3201, the extension slide bar 3202 is slidingly connected to the sealing plate 3102, and a pressing-down block 3203 is fixedly connected to the bottom of the pressing-down slide rod 3201.

[0044] Further, the staff only needs to press the pressing cap 3104 downward to drive the pressing-down block 3203 to push the plugging valve block 1203 downward to complete the opening and closing of the connecting port 1302, and after the staff releases the pressing force on the pressing cap 3104, the pressing cap 3104 can quickly rebound under the action of the return spring 3103, so that the pressing-down block 3203 quickly separates from the inner ring of the connecting port 1302, and the pressed pressing-down block 3203 does not affect the passage of water in the connecting port 1302, facilitating the use of the staff.

[0045] In actual operation, when the device is used, the staff only needs to press the pressing cap 3104 downward, the pressing cap 3104 moves downward through the extension slide bar 3202 to drive the pressing-down block 3203 to move downward, the pressing-down block 3203 moves downward to push the plugging valve block 1203 to move downward, the plugging valve block 1203 moves downward to separate from the connecting port 1302, thereby releasing the plugging of the connecting port 1302, and then the water body can pass through the connecting port 1302 to enter the water outlet 41 on the left side of the faucet 4, and the staff can use the water after pressing the pressing cap 3104 downward, the pressing cap 3104 moves upward to reset under the action of the return spring 3103 through the pressing-down slide rod 3201.
