Description

Technical Field

[0001] The utility model relates to the field of bathrooms, in particular to a rotary faucet. Background Art

[0002] Stainless steel faucets are widely welcomed by the market due to their stable feel, corrosion resistance, and lead-free water flow. In order to ensure the convenience of use, the distance between the faucet spout and the bottom of the faucet needs to be higher than the foundation height (such as Figure 4 H1); On the basis of being higher than the foundation height, some people like the outlet pipe to be higher (such as Figure 4 H2), some people prefer the outlet pipe to be lower (such as Figure 4 Each faucet has its own waterway design and production, which increases the difficulty of production. Once the market demand changes, the main parts of the faucets that have been produced will be unsalable.

[0003] The hot and cold water inlet and valve core installation water channels of the rotary faucet are concentrated on the lower faucet body at the bottom, and the upper faucet body at the top is connected to the water outlet pipe. Its structure is relatively simple, and the cost of reproducing the upper faucet body is relatively low. In addition, the outer shell of the rotary core itself has a height, and the depth of the hole where the outer shell is installed cannot be lower than the height of the outer shell itself. If the outer shell of the rotary core is installed in the upper faucet body, the heights of H2 and H3 will be greater than the height of the outer shell of the rotary core itself.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content
