Description

Technical fields:

[0001] This utility model belongs to the field of hardware manufacturing technology, specifically relating to a faucet with a side inlet valve core. Background Technology

[0002] Valve cores are widely used in kitchen and bathroom faucets. Traditional valve cores use a bottom-inlet design, requiring complex internal partitions to separate hot and cold water channels. Furthermore, the faucet body housing the valve core needs corresponding water-resistant partitions to accommodate it. Figure 2 As shown, this leads to problems such as increased material consumption, complex casting process (high rate of sand holes and porosity defects), and increased flow channel resistance (affecting water output efficiency). Therefore, a new type of faucet is urgently needed to solve the above technical problems. Utility Model Content:

[0003] The technical problem to be solved by this utility model is to provide a faucet with a side inlet valve core. Compared with ordinary mixing faucets, this faucet with a side inlet valve core eliminates the traditional partition wall and utilizes the outer wall of the valve core to naturally form an independent flow channel with the inner cavity of the faucet, which can reduce costs and improve product yield.

[0004] The technical solution of this utility model is to provide a faucet with a side inlet valve core, including a faucet body, a longitudinally arranged installation cavity, a valve core installed in the installation cavity, a cold water inlet cavity and a hot water inlet cavity respectively on the left and right sides of the installation cavity, and an outlet cavity at the front end of the installation cavity. The inner circumference of the installation cavity is adapted to the valve core and is not separated by a partition wall. The side wall of the valve core has a cold water inlet and a hot water inlet, and the bottom of the valve core has an outlet. The cold water inlet is connected to the cold water inlet cavity, the hot water inlet is connected to the hot water inlet cavity, and the outlet is connected to the outlet cavity.

[0005] Preferably, the cold water inlet and the hot water inlet are symmetrically arranged on both sides of the valve core sidewall.

[0006] Preferably, the valve core comprises a valve core cover, a valve stem, a fixed seat, a rotating shaft, a moving ceramic plate, a sealing ceramic plate, a positioning base, and a housing base. One end of the valve stem is inserted into the valve core cover, and the other end passes through the fixed seat and connects to the positioning base. The rotating shaft is inserted into one side of the fixed seat and connected to the valve stem to allow the valve stem to rotate within the fixed seat. The moving ceramic plate and the sealing ceramic plate are arranged vertically and the positioning base secures the moving ceramic plate assembly. One side of the housing base has a hot water inlet, and the other side has a cold water inlet. The bottom of the housing base has an outlet... Water inlet; a first water inlet groove is provided on one side of the moving ceramic plate, and a second water inlet groove is provided on the other side. A water outlet hole is provided in the middle of the sealing ceramic plate. Hot water inlet hole and cold water inlet hole are provided on both sides of the water outlet hole respectively. The bottom surface of the sealing ceramic plate is also recessed with a hot water flow channel for connecting the hot water inlet hole and the hot water outlet, and a cold water flow channel for connecting the cold water inlet hole and the cold water outlet. When the moving ceramic plate rotates under the action of the valve stem, the first water inlet groove can connect or disconnect the hot water inlet hole and the hot water outlet, and the second water inlet groove can connect or disconnect the cold water inlet hole and the cold water outlet.

[0007] Preferably, the cold water channel and the hot water channel have semi-circular cross-sections and are horizontally recessed on the bottom surface of the sealing ceramic plate.

[0008] Preferably, the valve stem has limiting protrusions on both sides, and the fixed seat has limiting grooves that cooperate with the limiting protrusions. The limiting protrusions can be accommodated and limited in the limiting grooves, thereby restricting the valve stem to rotate only within a specific angle range.

[0009] Preferably, the valve stem can rotate 22°.

[0010] Preferably, the upper opening of the mounting cavity is used to install the valve core.

[0011] Preferably, the mounting cavity is a cylindrical cavity.

[0012] Preferably, the water outlet chamber is equipped with a switching component, and the water outlet end of the water outlet chamber is equipped with an aerator.

[0013] Furthermore, the faucet body is cast in one piece.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This invention achieves side water intake by opening cold / hot water inlets on the side wall of the valve core housing, and features an integrated flow channel design that eliminates the need for traditional partitions. It utilizes the valve core side wall and the faucet cavity to naturally form an independent flow channel, thus solving the problems of complex processing and material waste caused by setting up partitions in the prior art. This improves production efficiency, product yield, and water output efficiency. Attached image description:
