Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a press-type water-dividing valve core. Background Art

[0002] As the core component of a faucet, the valve core primarily relies on the movement of the valve stem to achieve basic functions such as directional control, pressure control, or flow control. Currently, valve cores on the market can be divided into three types based on their functions: the first is the on-off valve core, which is used to open and close the water supply pipeline; the second is the mixing valve core, which controls the opening and closing of the cold and hot water inlet channels and adjusts the water temperature. Some mixing valve cores can also adjust the water volume; the third is the water diversion valve core, which can control the direction of water flow and distribute the water outlet channels. Depending on the spray system, water diversion valve cores are generally divided into two types: two-way water diversion (shower head and faucet) and three-way water diversion (shower head, overhead sprayer, and faucet).

[0003] As an essential accessory in the bathroom industry, water diversion valve cores have been used in a variety of products to divert water. However, most of the existing water diversion valve cores achieve water diversion in a rotating manner, which is not convenient to use. In recent years, there are more and more push-type and pull-type water diversion valve cores. However, the structures of the existing push-type and pull-type water diversion valve cores are relatively complex, and there is a common problem of difficulty in balancing sealing and installation convenience.
