Description

Technical Field

[0001] This application relates to the technical field of kitchen faucets, and particularly to a kitchen faucet with an integrated pure water valve core. Background Art

[0002] A kitchen faucet is a common facility installed on a kitchen sink. The opening and closing of the water flow can be controlled by rotating a handle or a lever. At the same time, the user can adjust the strength of the water flow as needed through the handle or the lever to make it suitable for different scenarios. In existing kitchen faucets of water purifiers, the pure water outlet valve core and the mixed water outlet valve core are separate. Usually, the mixed valve core is placed on the right, and the pure water valve core is placed on the left, or the pure water valve core is separately placed on the bracket and the other end of the water outlet pipe. Such a design will increase a lot of material and part costs, resulting in a relatively high unit price for the whole set of water purifier faucets. In addition, the operation is inconvenient and cannot meet the existing market demand.

[0003] When an existing kitchen faucet with an integrated pure water valve core is actually used, since the pure water outlet valve core and the mixed water outlet valve core are separate, the product will occupy a large usage space. When the customer uses it, both hands are required for operation, and it is impossible to achieve pure water outlet and mixed water outlet with one hand at the same time, which has certain limitations.

[0004] Therefore, it is necessary to invent a kitchen faucet with an integrated pure water valve core to solve the above problems. Summary of the Invention

[0005] This application provides a kitchen faucet with an integrated pure water valve core to solve the problem that both hands are required for operation when the customer uses the faucet, and it is impossible to achieve pure water outlet and mixed water outlet with one hand at the same time.

[0006] This application provides a kitchen faucet with an integrated pure water valve core, including a zinc alloy main body housing. The inside of the zinc alloy main body housing is threadedly connected with a water outlet pipe through screws.

The pure water PEX pipe 304 is sleeved on the surface of the outlet pipe 2. Two O-rings A 305 are sleeved on the bottom of the pure water connector 302.

[0033] The PEX pipe compression cap 303 can prevent the pure water PEX pipe 304 from falling off or leaking water from the surface of the pure water connector 302 during use.

[0034] Among them, the mouthpiece shell 401 is threadedly connected to the bottom of the water outlet of the outlet pipe 2. The pure water aerator 402 is lapped inside the mouthpiece shell 401. The sealing rubber 403 is lapped on the top of the pure water aerator 402. The pure water PEX pipe 304 is sleeved on the top of the pure water aerator 402.

[0035] The sealing rubber 403 can increase the friction and sealing performance between the connecting parts.

[0036] Among them, a plastic water purification valve seat 5 is sleeved inside the zinc alloy main body housing 1, and a fixing component 6 is threadedly connected inside the zinc alloy main body housing 1. The fixing component 6 includes a mounting screw copper 601 threadedly connected inside the zinc alloy main body housing 1. A base 602 is sleeved on the surface of the mounting screw copper 601. A fixing nut 603 is threadedly connected to the bottom of the mounting screw copper 601. An installation rubber 604 is lapped on the top of the fixing nut 603.

[0037] The base 602 facilitates the personnel to limit and fix the equipment.

[0038] Among them, a water purification mixing valve core 7 is lapped on the side of the plastic water purification valve seat 5. A valve core pressing cap 8 is threadedly connected inside the zinc alloy main body housing 1. A decorative cover 9 is threadedly connected to the side of the valve core pressing cap 8.

[0039] The water purification mixing valve core 7 can facilitate the personnel to realize the functions of discharging both pure water and mixed water by manipulating the valve core rod.

[0040] Among them, a valve core rod is fixedly connected to the side of the water purification mixing valve core 7, and a handle 10 is threadedly connected to the surface of the valve core rod through a screw.

[0041] The handle 10 can facilitate the personnel to control the opening and closing of the water flow.

[0042] Among them, an anti-wear plastic gasket 11 is sleeved at the bottom of the water outlet pipe 2, a plastic snap ring 12 is sleeved at the bottom of the water outlet pipe 2, and an O-ring B 13 is sleeved at the bottom of the water outlet pipe 2.

[0043] The O-ring B 13 can increase the friction force and prevent the loosening or displacement of the equipment connection.

[0044] Working principle: When this kitchen faucet with an integrated pure water valve core is in use, when the handle 10 is turned forward, the valve core rod on the water purification mixing valve core 7 is manipulated to make the water inlet hole and the water outlet hole of the plastic water purification valve seat 5 and the water purification mixing valve core 7 communicate with each other. Pure water will flow in through the water inlet hole of the plastic water purification valve seat 5, flow out from the water outlet hole of the plastic water purification valve seat 5, then flow into the water inlet hole of the water purification mixing valve core 7, flow out from the water outlet hole of the water purification mixing valve core 7, then flow into the water purification cavity through the water inlet hole of the plastic water purification valve seat 5, and then flow into the inner hole of the water purification joint 302 from the water purification cavity, then flow into the inner cavity of the water purification PEX pipe 304 from the inner hole of the water purification joint 302, and flow through the cavity to the water purification bubbler 402, and finally flow out through the water outlet hole of the water purification bubbler 402.

[0045] When the handle 10 is opened to the right, after the valve stem on the water purification mixing valve core 7 is also opened to the right, the cold and hot water inlet holes and the mixed water outlet hole on the plastic water purification valve seat 5 and the water purification mixing valve core 7 are interconnected. Then, the water purification mixing valve core 7 is rotated forward and backward by the handle 10 to adjust the outlet temperature of the ordinary mixed water. The larger the angle at which the handle 10 is opened forward, the higher the outlet temperature; the larger the angle at which the handle 10 is opened backward, the lower the outlet temperature. When cold and hot water flow in from the two cold and hot water inlet holes of the plastic water purification valve seat 5, flow out through the two cold and hot water outlet holes of the plastic water purification valve seat 5, then flow in from the two cold and hot water inlet holes of the water purification mixing valve core 7, and after the water purification mixing valve core 7 is opened to the right, the cold and hot water flowing into the water purification mixing valve core 7 will converge, intertwine and mix together to become mixed water. The mixed water will flow out through the mixed water outlet hole of the water purification mixing valve core 7, then flow into the plastic water purification valve seat 5 through the mixed water inlet hole, flow out from the mixed water outlet hole of the plastic water purification valve seat 5, flow through the inlet nut 301 to the inner cavity of the outlet pipe 2, and finally flow out through the cavity of the water purification bubbler 402 for mixed water.

[0046] In summary, through the settings of the outlet assembly 3, the connection assembly 4, the plastic water purification valve seat 5, the water purification mixing valve core 7 and the handle 10, the user combines the two valve core structures of the pure water valve core and the mixing valve core into the water purification mixing valve core 7, and realizes the functions of discharging both pure water and mixed water by controlling the valve stem of the water purification mixing valve core 7. When in use, the user can complete all operations with one hand, without the need to use the left hand to discharge purified water and the right hand to discharge mixed water. The product operation is more convenient and flexible, occupies less space, and brings a better use experience to the customer. At the same time, the product main body is changed from the original all-copper main body to a zinc alloy shell with a plastic water purification valve seat 5, and the cost is much lower than that of the all-copper one. The product is more cost-effective compared to the copper main body products, improving the market competitiveness of the product.
