[0029] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0030] The faucet in 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. During installation, the valve core body needs to be pushed into the flow channel in the faucet body first, and it 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] A one-piece valve core angle valve comprises a body 3, a ball valve core 4 and a handwheel 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 to the top of the body 3. The raised portion above the ball valve core 4 is connected to the handwheel 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.

[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 one-piece ball valve core 4 does not require the production of a connecting rod during production.

[0035] When in use, the faucet starts to flow when the handwheel 5 is turned in the preset direction so that the side opening of the ball valve core 4 overlaps the water outlet of the body 3. The faucet is closed when the handwheel 5 is turned in the opposite direction so that the side opening of the ball center moves away from the water outlet of the body 3. Since there is no need to connect the handwheel 5 and the ball valve core 4 through a connecting rod, the turning force of the handwheel 5 is directly applied to the ball valve core 4, avoiding the loosening of the connecting rod and the resulting inconvenience in operation.

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

[0037] An integrated valve core angle valve, such as Figure 1 As shown, the faucet includes a body 3, a ball valve core 4 and a handwheel 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 to the top of the body 3. The raised portion above the ball valve core 4 is connected to the handwheel 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 the water inlet, a water outlet is provided on the side of the body 3 near the top, and a thread for installation and connection with a water pipe is provided at the bottom of the body 3.

[0039] During installation, the integrally formed ball valve core 4 eliminates the need for connecting rods during production, and there is no need to use connecting rods to connect the ball valve core 4 body. Simply push the ball valve core 4 to the top of the body 3 and allow the raised portion on the top of the ball valve core 4 to pass through the hole above the body 3 and then connect it to the handwheel 5. This simplifies the structure of the faucet 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 through 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 erosion caused by metal pipes. However, faucets are generally made of metal. The instantaneous water pressure when turning the faucet on and off will inevitably increase the erosion of the inner surface of the metal faucet, allowing erosion objects that are harmful to human health to enter the water.

[0042] Therefore, a non-metallic inner shell is required within the faucet. However, making a faucet with a non-metallic inner shell combined with a metal outer shell increases production complexity. To mitigate the problem of water erosion against metal pipes and reduce production complexity, the integrally molded ball valve core 4 is designed as an integrally molded non-metallic ball valve core 4. Furthermore, a non-metallic ferrule and a non-metallic ring that fits within the ferrule are embedded within 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 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 there are inevitably some 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 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 first 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. The side of the non-metallic sleeve 8 is provided with a water hole, 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 equipped with an upper O-ring 7 and a lower O-ring 9. The top of the sleeve 8 is also provided with a concave-convex structure 31, the width of which is smaller 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 present utility model has the following advantages:

[0053] The concave-convex structure 31, combined with the integrally molded ball valve core 4, eliminates the need for screws during installation, improving installation convenience. Since screws are not required for installation, the holes or grooves required for screws do not need to be matched during production, which improves overall production convenience and facilitates application in automated production. The integrally molded ball valve core 4 eliminates the need for a connecting rod, increasing the water flow rate compared to existing products. It is also 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. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
