Description

Valve core and faucet Technical Field

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

[0002] In the traditional faucet structure, water flows directly through the outer shell of the faucet. After long-term use, the outer shell will be corroded by water and will produce certain lead pollution and other heavy metal pollution, which seriously affects people's domestic water safety. Existing healthy and environmentally friendly faucets usually connect the water outlet of the valve core and the water outlet of the faucet through an environmentally friendly water outlet hose. In the existing technology, the water outlet arm of the faucet is usually placed on the side of the valve core installation cavity, so that the water outlet of the valve core and the water outlet arm have a certain height difference. This will cause the water outlet hose connecting the water outlet of the valve core to be connected to the water outlet of the faucet through the water outlet arm, and will bend at the connection between the water outlet arm and the installation cavity, which will lead to a small water flow rate, affecting the product user experience.

[0037] Specifically, as shown in Figures 1 to 5, this embodiment includes an outer shell 1, a valve plate control assembly for controlling the waterway, a base 2 provided with a hot water inlet 3, a cold water inlet 4, and a water outlet 5; the water outlet 5 is a mixing outlet that communicates with the mixing chamber within the valve core; the base 2 is provided with a bottom-open mounting groove 6; a sloped portion 7 extends through the outer shell 1; the sloped portion 7 is set at a 20-degree angle to accommodate most faucets. The hot water inlet 3 and the cold water inlet 4 are respectively provided on either side of the mounting groove 6; the water outlet 5 is arranged opposite the sloped portion 7 of the mounting groove 6 and is positioned within the mounting groove 6, allowing the water outlet hose 14 to pass directly through the mounting groove 6 and enter the faucet's outlet arm 10, thereby preventing the water outlet hose 14 from bending. Positioning posts 8 are provided on either side of the mounting groove 6 of the base 2; these posts 8 facilitate the installation of the valve core into the valve core mounting cavity of the faucet body 9.

[0038] In another embodiment, as shown in Figures 6 to 8, the hot water inlet 3 and the cold water inlet 4 are respectively arranged on both sides of the installation groove 6; the water outlet 5 is arranged opposite to the inclined portion 7 of the installation groove 6; the valve core is suitable for a faucet with a pull-out function of the water outlet head.

[0039] By providing the mounting groove 6 with a bottom opening on the valve core base 2 and the inclined portion 7, the water outlet hose 14 will not bend at the connection point between the water outlet arm 10 and the valve core mounting cavity when the water outlet 5 of the valve core is connected to the faucet water outlet 11 via the water outlet arm 10, thereby preventing the water outlet flow from being too small.

[0040] Preferably, the inclined portion 7 is set to be inclined at 5 degrees to 60 degrees; the angle of the inclined portion 7 is set according to the height difference between the water outlet 5 of the valve core and the water outlet channel of the faucet 10 and the connection point of the valve core installation cavity, which can maximize the smooth transition of the water outlet hose 14.

[0041] The present invention also provides a faucet, as shown in Figures 9 and 10. In this embodiment, it includes a faucet body 9 provided with a water outlet arm 10, and the water outlet arm 10 is provided with a water outlet channel, and the water outlet channel connects the water outlet 5 and the valve core installation cavity of the faucet, and also includes a hose assembly and the valve core 100; the hose assembly includes a water outlet hose 14 and an adapter seat 12, after the hose assembly passes through the water outlet channel, its adapter seat 12 is connected to the water outlet 5 of the valve core, and the water inlet of the adapter seat 12 forms an angle with the connecting end of the water outlet hose 14 and the adapter seat 12, and the angle is adapted to the inclined portion 7 of the mounting groove 6.

[0042] The faucet outlet 11 is connected to the water outlet 5 through the outlet hose 14. As shown in Figures 11 to 13, the adapter 12 includes a first connection portion 15 provided with the water inlet and a second connection portion 16 connected to the outlet hose 14. The first connection portion 15 is used for sealing connection with the water outlet 5; the second connection portion 16 is arranged with an inclination relative to the inclined portion 7. A special-shaped sealing ring 13 is provided on the first connection portion 15, and the outer surface of the special-shaped sealing ring 13 is in the shape of an arc. The outlet hose 14 directly enters the outlet arm 10 through the mounting groove 6 of the base 2 at the outlet 5 connected to the valve core to connect to the faucet outlet 11. This method allows the outlet hose 14 to have a smoother transition at the connection point between the outlet arm 10 and the mounting groove 6.

[0043] The installation of the faucet is more convenient by setting the mounting groove 6 of the base 2. You only need to insert the water outlet hose 14 connected to the adapter 12 into the mounting groove 6 of the base 2 through the water outlet arm 10, set the special-shaped sealing ring 13 upward, and then install the valve core 100 downward so that the water outlet 5 of the base 2 presses the special-shaped sealing ring 13; and the greater the pressing force, the better the sealing performance.

[0044] In another faucet embodiment, a pipe installation cavity is provided below the valve core installation cavity; the hot water inlet 3, the cold water inlet 4, and the water outlet 5 are placed in the pipe installation cavity through a through-hole at the bottom of the valve core installation cavity; one end of the water outlet hose 14 is connected to the water outlet 5, and the other end passes through a through-hole corresponding to the base installation groove 6, passes through the installation groove 6, and is connected to the faucet water outlet 11 through the water outlet channel on the water outlet arm 10. A counterweight is hung on the portion of the water outlet hose 14 placed in the pipe installation cavity to ensure that the water outlet hose 14 automatically resets under the action of the weight of the counterweight after being pulled.

[0045] The valve core and faucet provided by the present invention, through the arrangement of the valve core base mounting groove 6 and the arrangement of the inclined portion 7, ensure that the water outlet hose 14, when connected to the valve core's water outlet 5 through the water outlet channel of the water outlet arm 10 to the faucet water outlet 11, will not bend at the connection point between the water outlet arm 10 and the valve core mounting cavity, which would result in a low water flow rate. Furthermore, the angle of the inclined portion 7 is adjusted according to the height difference between the valve core's water outlet 5 and the faucet's water outlet arm 10, which can maximize the smooth transition of the water outlet hose 14. At the same time, the use of this valve core makes the installation of the faucet more convenient. Through the setting of the adapter seat 12 and the special-shaped sealing ring 13, it is only necessary to pass the water outlet hose 14 connected to the adapter seat 12 through the water outlet channel of the water outlet arm 10 into the installation groove 6 of the base 2, so that the special-shaped sealing ring 13 is set upward, and then the valve core 100 is installed downwardly so that the water outlet 5 of the base 2 presses the special-shaped sealing ring 13; and the greater the pressing force, the better the sealing.
