Description

A valve core and a pull-out faucet

technical field

The invention relates to a valve core, in particular to a valve core; the present invention also relates to a pull-out faucet.

Background technique

The pull-out faucet is one of the existing faucets. The water outlet of the faucet is connected with the pull-out pipe and can be pulled out from the faucet to facilitate flushing. The existing pull-out faucets all use traditional valve cores, and a separate valve core cavity needs to be set on the faucet body for installing the valve core. Multiple pipes need to be connected in the faucet body to introduce the cold and hot water from the outside into the faucet body. At the same time, it is also necessary to set up a pipeline to lead out the mixed water in the valve core, and then connect the pulling hose, and pass the pulling hose into the main body of the faucet to connect with the water outlet. As a result, the main structure of the faucet is large, there are many internal pipes, and the connection is more troublesome. At the same time, the pull hose and other pipes are prone to jam.

The Chinese Patent No. 202022048003.6 discloses a hollow valve core with a through hole penetrating the valve core in the middle of the valve core, so that the pulling hose can be pulled directly through the through hole for pulling. Although the valve core can simplify the waterway structure inside the main body of the faucet and facilitate the connection of pipes, the moving piece of the valve core is provided with two first water inlet holes and a water mixing chamber on the front, and two blind grooves are set on the back of the moving piece The two ends of each blind groove are respectively connected with one water inlet hole 1 and one end of the mixed water cavity, so that the water of the two water inlet holes 1 can flow into the mixed water cavity. The blind groove overlaps with the first part of the water inlet hole and the end of the mixing chamber respectively through the two ends, and connects the two, resulting in a complex overall structure of the moving piece, inconvenient processing, and limited flow.

Due to the unreasonable waterway design scheme of the above-mentioned patent, it is necessary to set up a complex waterway on the small moving valve plate, so that the flow rate of the valve is greatly reduced; at the same time, precise coordination is required between the moving valve plate and the fixed valve plate to achieve rotary sealing , The complex waterway is set in the moving valve plate and the fixed valve plate, the flatness of this valve plate or fixed valve plate is not easy to control, so that the valve leaks during use.
