[0002] When renovating existing homes, hotels or office buildings, an angle valve is usually installed at the water pipe interface buried inside the wall, and then a metal braided hose is used to connect the basin faucet, toilet, water heater or sink faucet and other bathroom equipment. Early angle valve products only realized the simple stop valve function, that is, the function of opening and closing, so as to facilitate the installation and maintenance of bathroom products. However, as modern bathroom equipment adopts a large number of ceramic plate plane sealing technology and sets a bubbler at the water outlet, the requirements for water purity are increasing day by day, to prevent impurities from being embedded in the ceramic plate plane to cause wear or block the bubbler at the faucet outlet.

[0003] The angle valve currently in use only has a switching function through a ball valve unit, but the ball valve unit often needs to be assembled in sequence through multiple parts such as multiple elastic sealing rings, a metal valve ball, a connecting rod detachably connected to the metal valve ball, a handle, etc., which is relatively cumbersome.

[0024] The following is combined with Figure 1-7 The present invention is further illustrated with examples.

[0025] Embodiment: A filtering angle valve which is easy to install comprises a valve body 1, a ball valve unit and a filtering unit.

[0026] The valve body 1 is provided with a water inlet 2 and a water outlet 3, and the water inlet 2, the ball valve unit, the filter unit, and the water outlet 3 are connected in sequence. A conversion chamber 4 for installing the ball valve unit is provided in the valve body 1. A mounting chamber 25 for installing the filter unit is provided on one side of the valve body 1 close to the water outlet 3, and a mounting port 26 is provided on one side of the mounting chamber 25. The filter unit is installed in the mounting chamber 25 through the mounting port 26. The filter unit includes a threaded cover 27 and a cylindrical filter screen 28 that are fixedly connected to each other. The threaded cover 27 and the mounting port 26 form a threaded fixed fit. A second sealing ring 29 is provided between the threaded cover 27 and the mounting port 26. The cylindrical filter screen 28 is located inside the threaded cover 27. The cylindrical filter screen 28 is vertically arranged with the water outlet 3 and covers the inner end of the water outlet 3. The valve body 1 is an integral injection molding, and the valve body 1 is molded by an injection molding machine by covering the outer side of the lower part of the ball valve unit. First, the ball core 5, the sealing component, and the ball rod 15 are assembled, and then the assembly is installed on the injection molding machine. Then, the outer side of the lower part of the assembly is covered with injection molding, and then the outer handle 16 is clamped and installed on the assembly. The one-piece injection molding of the valve body 1 can significantly improve the sealing performance of the valve body 1.

[0027] The ball valve unit comprises a ball core 5, a sealing sleeve 6 and a handle 7. The ball core 5 is provided with a radial inner through hole 8, and the ball core 5 is sealed and movably sleeved in the sealing sleeve 6. The lower end of the ball core 5 is provided with a first dome portion 14 protruding downward, and the first dome portion 14 is embedded with a first circular groove provided at the lower end of the inner surface of the sealing sleeve 6. The arrangement of the present application can effectively prevent the ball core 5 and the sealing sleeve 6 from tilting during operation. The ball core 5 is made of plastic material, and the upper end of the ball core 5 is provided with a ball rod 15 integrally molded and injected with it. The ball rod 15 movably seals and passes through the upper opening, and the upper end of the ball rod 15 is provided with an outer handle 16, and the ball rod 15 and the outer handle 16 constitute the handle 7. The upper opening is sealed and connected to the handle 7, and the lower end of the handle 7 passes through the sealing sleeve 6 and is fixedly connected to the upper end of the ball core 5, which is used to control the rotation of the ball core 5 relative to the sealing sleeve 6, thereby controlling the opening and closing between the water inlet 2 and the water outlet 3. The application uses plastic material to greatly save the material cost, making the product cost less than half of the original metal ball valve, but the durability of the plastic material itself is lower than that of the metal material. If the original ball valve structure is simply used, there is often a technical problem of cracking the ball core 5. The application uses an integral injection molding method to form the ball core 5 and the ball rod 15 at its upper end, which significantly improves the structural stability of the ball core 5.

[0028] The sealing sleeve 6 is installed in the conversion chamber 4 in a locking and sealing manner, and the sealing sleeve 6 is provided with a radial outer through hole 9. The outer edges of both ends of the sealing sleeve 6 relative to the radial outer through hole 9 are provided with an integrally raised annular sealing portion 10, and the annular sealing portion 10 and the annular groove 11 provided in the conversion chamber 4 form a sealing locking fit. The provision of the annular sealing portion 10 can not only improve the sealing performance between the ball valve unit and the valve body 1, but also effectively prevent the sealing sleeve 6 from rotating together during the rotation of the ball core 5. The sealing sleeve 6 is a spherical structure, and the sealing sleeve 6 is provided with an outwardly protruding locking isolation ring 12 on the middle outer surface relative to the two annular sealing portions 10, and the locking isolation ring 12 and the annular locking groove 13 provided in the conversion chamber 4 form a locking and sealing fit. Thereby limiting the circumferential rotation of the sealing sleeve 6, in addition, the structure of the locking isolation ring 12 has a good sealing effect, thereby preventing the liquid from passing between the valve body 1 and the sealing sleeve 6.

[0029] The outer handle 16 includes a handle body 17, one end of which is provided with a locking hole 19, the locking hole 19 and the club 15 form a detachable buckle fit, and the upper end of the locking hole 19 is detachably installed with a handle cover 18 that forms a cover fit with the locking hole 19. The setting of the handle cover 18 greatly optimizes the difficulty of the injection molding process of the handle body 17 itself, and optimizes the structure and cost of the handle body 17 itself. The handle cover 18 can be disassembled at any time, so that the user can intuitively see the connection status of the club 15 and the locking hole 19, whether there is wear on the upper end of the club 15, etc., which is convenient for the user's maintenance and inspection. A first sealing ring 23 is provided between the outer handle 16 and the valve body 1, and the first sealing ring 23 can not only play a sealing effect, but also form a certain elastic buffer effect on the outer handle 16 and the valve body 1.

[0030] The upper end of the club 15 is provided with two L-shaped locking grooves 20 distributed in the circumferential direction, and the L-shaped locking grooves 20 include a vertical locking groove and a transverse locking groove located at one side of the bottom of the vertical locking groove. The handle body 17 is provided with two locking blocks 21 protruding radially inward, and the locking blocks 21 are engaged with the transverse locking groove through the vertical locking groove. The lower end of the handle cover 18 is provided with a locking tongue 22 protruding downward, and the locking tongue 22 and the vertical locking groove are engaged in a plug-in fixed manner, which is used to lock the relative position of the club 15 and the outer handle 16. The lower part of the club 15 is provided with an annular flange 24, and the upper part of the sealing sleeve 6 is provided with an integrally extended protruding end 30, and the protruding end 30 is provided with an annular groove 31 corresponding to the annular flange 24, and the annular flange 24 is movably installed in the annular groove 31, and the annular flange 24 and the annular groove 31 form a sealing limit fit. The thickened protruding end 30 can effectively prevent the club 15 from causing damage to the sealing sleeve 6 during the rotation process. The provision of the annular flange 24 and the annular groove 31 can not only effectively improve the sealing performance between the sealing sleeve 6 and the ball core 5, but also prevent the ball shaft 15 from tilting and breaking during use.

[0031] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to exhaust all implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
