Faucet valve core with water mixing and distributing functions

Abstract

A faucet valve element with water mixing and dividing functions comprises a valve shell, a water mixing operation valve rod and a water dividing operation valve rod, a lower cavity and an upper cavityare formed in the valve shell, a water mixing valve plate assembly is arranged in the upper cavity, and a water dividing valve plate assembly is arranged in the lower cavity. A water mixing cavity inthe water mixing valve plate assembly is communicated with a water dividing cavity in the water dividing valve plate assembly; the valve shell is provided with a first water inlet, a second water inlet and a plurality of water outlets. The water mixing operation valve rod is sleeved outside the water dividing operation valve rod; the faucet valve core is characterized in that the first water inlet is formed in the side wall of the upper cavity; the second water inlet is formed in the side wall of the lower cavity, a water passing hole used for being communicated with the water mixing cavity is formed in the top wall of the lower cavity, the water passing hole is communicated with the second water inlet through a water passing flow channel so that water entering from the second water inletcan enter the water mixing cavity through the water passing flow channel and the water passing hole from bottom to top, and the water outlet is formed in the bottom of the lower cavity. The faucet valve element waterway structure is more reasonable and compact in layout, and operation is more user-friendly.

Description

technical field [0001] The invention relates to a faucet spool, in particular to a faucet spool having both the functions of mixing water (controlling the opening and closing of the water inlet channel and adjusting the water temperature) and water diversion (distributing the water outlet of the water flow). Background technique [0002] The faucet spool can be divided into two categories according to its function. One is the water mixing spool, which is used to control the opening and closing of the water inlet of cold water and hot water, adjust the water temperature, and some mixing water spools can also adjust the water volume. The other type is the water diversion valve core, which can control the water flow direction and distribute the water outlet channels. The water diversion valve core is divided into two water diversions (shower and faucet) and three water diversions (shower sprinkler) due to different sprinkler systems. , top spray and faucet) two. Due to the lim...

AI Technical Summary

Problems solved by technology

[0005] 1. Because the water diversion operation valve stem is set outside the water mixing operation valve stem, this makes the water diversion operation knob located on the outer edge, and the mixed water operation knob passes through the water diversion operation knob and is located in the middle, that is, the outer ring knob performs water diversion operation, and the inner ring The knob is used for water mixing operation. In actual use, the water division operation is generally only performed once and the operation time is short, while the water mixing adjustment will be performed multiple times and the operation time is long. The small area of ​​the inner ring knob is not conducive to operation, and because of The ring knob is relatively easy for users to access, so when performing mixed water operations, the outer ring knob may be misoperated, which will easily lead to operational errors and the operation is not humanized enough.

[0006] 2. The hot water inlet channel, the cold water inlet channel and the ports of the three outlet channels are all located on the bottom of the valve housing, resulting in crowded waterway layout at the bottom of the valve housing. In the case of the bottom of the same cross-sectional area, each port can only be made smaller , affect the efficiency of water inlet and outlet. If you want to enhance the efficiency of water inlet and outlet, you can only make the valve housing bigger, which is not conducive to processing and installation on the faucet, and increases the cost
