Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a faucet anti-drip device and a faucet. Background Technique

[0002] A faucet is a common name for a water valve, which is used to control the size of the water flow switch and has the effect of saving water. The replacement speed of faucets is very fast, developing from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control faucet, the stainless steel double-temperature double-control faucet, and the kitchen semi-automatic faucet.

[0003] The utility model patent application document with the publication number of "CN211693646U" discloses a faucet anti-drip device and a faucet, which mainly consists of a pipeline, a sleeve, a sealing rod group, and a sealing boss. This technical solution installs a telescopic sealing rod assembly in the sleeve, and at the same time sets a sealing boss in the sleeve to cooperate with the sealing rod assembly to form a seal. When the pipeline is installed at the faucet water outlet, if the faucet drips at this time, the sealing structure formed by the sealing rod assembly and the sealing boss will block the dripping water between the sealing structure and the faucet water outlet. When water is needed, the faucet is opened, and the water pressure is relatively large. The sealing rod assembly will be compressed by force and separated from the sealing boss to conduct, so that the dripping phenomenon of the faucet can be avoided without affecting the normal use of the faucet, thereby avoiding waste of water sources.

[0004] The above-disclosed faucet anti-drip device and faucet have the following defects: In the long-term use process of this technical solution, due to the single spring and the two sides of the spring being suspended and unable to support the spring, the spring is prone to deformation under the impact of water pressure for a long time, resulting in the sealing member not being able to fit with the water inlet hole and causing dripping, and the service life is relatively low.

[0005] It can be seen from this that the existing faucet anti-drip device and faucet do not have a good anti-drip structure, and it is necessary to improve the existing deficiencies and provide a faucet anti-drip device and a faucet. Summary of the Invention

[0006] The purpose of the utility model is to provide a faucet anti-drip device and a faucet to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a water faucet anti - dripping device, which comprises a water outlet pipe. One end of the water outlet pipe is fixedly installed with a first connecting pipe. A second connecting pipe is movably installed inside the first connecting pipe. An anti - dripping device is arranged inside the second connecting pipe. The anti - dripping device comprises a partition plate, a through - slot, a water - stopping column, a sealing layer, a mounting plate and a spring. The inner wall of the second connecting pipe is fixedly installed with the partition plate. A through - slot is opened on the upper surface of the partition plate. The inner wall of the through - slot is slidably connected with the water - stopping column. A sealing layer is arranged on the circumferential side of the water - stopping column. The sealing layer abuts against the through - slot. A plurality of mounting plates are fixedly installed on the circumferential side of the water - stopping column. The mounting plates are slidably connected with the inner wall of the second connecting pipe. Springs are fixedly installed on the upper surfaces of the mounting plates. One end of each spring is connected with the partition plate.

[0009] Further, a pressing plate is fixedly installed on the circumferential side of the second connecting pipe.

[0010] Further, a sealing gasket is fixedly installed on the upper surface of the pressing plate. The sealing gasket abuts against the lower surface of the first connecting pipe.

[0011] Further, an auxiliary block is fixedly installed on the circumferential side of the second connecting pipe. A metal hose is movably installed at one end of the second connecting pipe.

[0012] Further, a metal joint is fixedly installed at one end of the metal hose.

[0013] Further, the water faucet also comprises the anti - dripping device.

[0014] The utility model has the following beneficial effects:

[0015] (1) When the water faucet is opened in the utility model, the water pressure impacts the water - stopping column, driving the mounting plate to slide downward on the inner wall of the second connecting pipe. The mounting plate moves to stretch the spring, so that the water - stopping column moves out of the through - slot and the water source can flow out. When the water faucet is closed, the spring rebounds to retract the water - stopping column into the through - slot, and the sealing layer abuts against the inner wall of the through - slot, thus achieving the effect of preventing dripping. Since the mounting plate is slidably connected with the inner wall of the second connecting pipe, there is a certain guiding effect, which makes the spring not easily deformed, thereby increasing the service life.

[0016] (2) In the utility model, the second connecting pipe is screwed into the first connecting pipe through the auxiliary block. When tightened, the sealing gasket tightly fits against the lower surface of the first connecting pipe, so that the sealing performance at the connection is good and it is not easy to leak water. The metal hose can rotate, which increases the practicality during use.

[0017] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above - mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
