Integrated multifunctional pulling head water channel structure

Abstract

The invention relates to the field of faucets, and discloses an integrated multifunctional pulling head water channel structure. The pulling head water channel structure comprises a valve seat, the valve seat is integrally formed, and a main water channel is arranged in the valve seat. A first branch water channel, a second branch water channel and a flow increasing channel are arranged on the main water channel. The first branch water channel and the second branch water channel are arranged on a water outlet of the main water channel, and function switching mechanisms are arranged at the joints. The flow increasing channel is arranged close to a water inlet of the main water channel, and a flow control mechanism is arranged at the joint. According to the pulling head water channel structure, only one part is needed to form a water channel cavity, and a multi-water-channel function and the function of controlling flow through one key can be achieved; and the production cost is reduced, stability is improved, and the assembly process complexity is superior to that of a currently frequently-used pulling head structure.

Description

technical field [0001] The invention relates to the field of faucets, and discloses an integrated multi-functional drawing head waterway structure. Background technique [0002] The kitchen pull-out head (or pull-out faucet) is installed on a fixed faucet seat, and after being pulled out, it is separated from the restriction of the fixed faucet seat, so that the kitchen pull-out head can be used flexibly in a larger range. At present, in order to achieve multi-functional operation, the pull-out head of the kitchen faucet on the market is usually designed by connecting the front and rear switching components with screws or adopting the design of the water channel welding piece to achieve a multi-functional structural design. The disadvantages in the above structure are: 1. When the front and rear switching components are connected by screws, the structure of the locking screw is complicated, and many processes are added in the assembly, resulting in high cost. 2. When adopti...

Problems solved by technology

The disadvantages in the above structure are: 1. When the front and rear switching components are connected by screws, the structure of the locking screw is complicated, and many processes are added to the assembly, resulting in high cost

2. When adopting the design of waterway welded sheet to realize the multi-functional structural design, although the structural cost and complexity of the welded sheet are better than that of the locking screw structure, there are still hidden dangers of water leakage such as poor welding and high assembly costs.

[0003] In addition, although the commonly used pull-out head has a multi-functional water outlet structure, there must be multiple water diversion channels in the structure to meet the multi-functional water outlet. One kind of water flow function, it is difficult to realize the flexible switching of large and small water flow, therefore, it is necessary to provide a waterway cavity with one part, so that the waterway function switching waterway cavity does not need to use multiple parts assembly or welding to realize , so as to reduce the poor product function caused by unstable assembly and welding processes, reduce the production and assembly costs of the water channel structure of the pull head, and the structure of the water channel of the pull head can realize the function of switching between large and small water flow in one water channel with one key
