[0029] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] The faucet of the prior art is inseparable from the valve core, which is composed of a valve core body and a valve core connecting rod and is installed in the faucet body. When installing, the valve core body needs to be pushed into the flow channel in the faucet body first, and needs to be rotated to align the water outlet before connecting the valve core connecting rod.

[0031] The technical solution of the embodiment of the present application solves the problems of inconvenient installation and use or easy loosening in the prior art by providing an integrated valve core angle valve, and achieves the beneficial effects of easy installation and use and not easy to loosen under the one-piece molded ball valve core 4.

[0032] The overall idea of ​​the implementation scheme of the present invention to solve the above technical problems is as follows:

[0033] An integrated valve core angle valve comprises a body 3, a ball valve core 4 and a hand wheel 5. The ball valve core 4 is an integrally formed ball valve core 4, the ball valve core 4 passes through the vertical flow channel of the body 3 and is limited at the top of the body 3. The raised portion above the ball valve core 4 is connected to the hand wheel 5, and the side opening of the ball valve core 4 rotates relative to the water outlet of the body 3 with the vertical central axis of the body 3 as the axis.

[0034] During installation, there is no need to use a connecting rod to connect the ball valve core 4. Just push the ball valve core 4 to the top of the body 3 and let the raised part on the top of the ball valve core 4 pass through the hole above the body 3 and then connect it to the hand wheel 5. The production of the one-piece ball valve core 4 eliminates the need for a connecting rod.

[0035] When in use, when the hand wheel 5 is rotated in a preset direction so that the side opening of the ball valve core 4 overlaps with the water outlet of the body 3, water flows out of the faucet; when the hand wheel 5 is rotated in a direction opposite to the preset direction so that the side opening of the ball center is away from the water outlet of the body 3, the faucet is closed. Since the hand wheel 5 and the ball valve core 4 do not need to be connected by a connecting rod, the rotation force of the hand wheel 5 is directly applied to the ball valve core 4, avoiding the loosening of the connecting rod and causing inconvenience in operation.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] An integrated valve core angle valve, such as Figure 1 As shown, the faucet comprises a body 3, a ball valve core 4 and a hand wheel 5. The ball valve core 4 is an integrally formed ball valve core 4. The ball valve core 4 passes through the vertical flow channel of the body 3 and is limited at the top of the body 3. The raised portion above the ball valve core 4 is connected to the hand wheel 5. The side opening of the ball valve core 4 rotates relative to the water outlet of the body 3 with the vertical central axis of the body 3 as the axis. The opening and closing of the faucet is controlled by controlling the rotation of the integrally formed ball valve core 4.

[0038] The bottom of the body 3 is a water inlet, a water outlet is arranged on the side of the body 3 near the top, and a thread for installation and connection with a water pipe is arranged at the bottom of the body 3.

[0039] During installation, the one-piece ball valve core 4 does not need to be produced with a connecting rod, and there is no need to use a connecting rod to connect the ball valve core 4 body. The ball valve core 4 is pushed to the top of the body 3 and the raised part on the top of the ball valve core 4 passes through the hole above the body 3 and then connected to the hand wheel 5. The structure of the faucet is simplified as a whole. Figure 2 shown.

[0040] If water flows through metal, it will inevitably wash away the metal. The substances released by the washed metal may cause uncertain damage to the human body. For example, heavy metals or non-heavy metal substances may enter the body with drinking water and cause harm to the human body.

[0041] Most water pipes have been replaced with plastic pipes, which can alleviate the problem of water scouring metal pipes. However, faucets are generally made of metal. The instantaneous water pressure when turning on and off the faucet will inevitably increase the scouring of the inner surface of the metal faucet, allowing scouring substances that are not good for human health to enter the water.

[0042] Therefore, it is necessary to add a non-metallic inner shell in the faucet, but making a faucet with a non-metallic inner shell combined with a metal outer shell will increase the complexity of production. In order to meet the problem of slowing down the scouring of the metal pipe by water flow and reducing the problem of production complexity, the integrally formed ball valve core 4 is designed as an integrally formed non-metallic ball valve core 4. In addition, a non-metallic ferrule and a non-metallic ring adapted to the non-metallic ferrule are embedded in the water outlet of the faucet body.

[0043] Specifically, the non-metallic ball valve core 4 is a plastic ball valve core 4 .

[0044] Specifically, the non-metallic ferrule and the non-metallic ring are respectively a plastic ferrule 1 and an apron 2. The apron 2 is preferably a rubber ring 2.

[0045] More specifically, the integrally formed ball valve core 4 is also equipped with a plurality of valve core O-rings 6 , which need to be put on during installation.

[0046] Furthermore, in order to ensure that the handwheel 5 is not over-twisted to cause excessive friction between the ball valve core 4 and the inner wall of the faucet, it is necessary to install a rotation limiting structure on the handwheel 5, and a concave-convex structure 31 is provided on the top of the faucet body. The concave-convex structure 31 matches the inside of the handwheel 5. The maximum diameter of the concave-convex structure 31 is smaller than the diameter of the faucet body. The concave-convex structure 31 is divided into high and low semicircles, and the high semicircle part serves to limit the handwheel 5.

[0047] The use of non-metallic ball valve core 4 and non-metallic ferrule can prevent the running water from contacting the metal of the faucet. However, the length of the faucet body is often longer than the ball valve core 4, and inevitably there are local metal parts for water to flow through. In addition, the excessive length of the faucet body will cause inconvenience in installation.

[0048] In order to reduce the contact between water flow and metal and the convenience of installation, such as Figure 3 As shown, a non-metallic sleeve 8 is added, and the integrally formed ball valve core 4 is nested in the non-metallic sleeve 8. A through hole is provided at the top of the sleeve 8 to allow the integrally formed ball valve core 4 to pass through. During installation, the integrally formed ball valve core 4 is firstly nested in the non-metallic sleeve 8, and the top of the integrally formed ball valve core 4 passes through the through hole at the top of the non-metallic sleeve 8. A water hole is provided on the side of the non-metallic sleeve 8, and the side opening of the integrally formed ball valve core 4 is aligned with the water hole provided on the side of the non-metallic sleeve 8.

[0049] Furthermore, the non-metallic sleeve 8 is a plastic sleeve 8 .

[0050] Furthermore, the sleeve 8 is respectively provided with an upper O-ring 7 and a lower O-ring 9, and the top of the sleeve 8 is also provided with a concave-convex structure 31, the width of which is lower than the width of the concave-convex structure 31 at the top of the main body.

[0051] The installed faucet containing the sleeve 8 is as follows Figure 4 shown.

[0052] The integrated valve core faucet of the embodiment of the present invention has the following advantages:

[0053] The concave-convex structure 31 is combined with the integrally formed ball valve core 4, eliminating the need for screws during installation, thereby improving the convenience of installation. Since screws are not required for installation, it is not necessary to match the holes or patterns required for screws during production, which generally improves the convenience of production and facilitates application in automated production. The integrally formed ball valve core 4 eliminates the need for a connecting rod, which increases the water flow rate compared to products on the market, and is highly versatile and can be adapted to conventional faucets.

[0054] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
