Abstract
Description
Technical Field
[0001] This application relates to the field of mixing valve technology, and more specifically, to an anti-clogging, easy-to-disassemble suction-type mixing valve. Background Technology
[0002] Mixing valves are widely used in shower rooms to regulate the flow and ratio of hot and cold water to meet users' different water temperature needs. However, most existing mixing valves have an integral design, which makes it difficult to disassemble and replace parts when damaged, resulting in high maintenance costs and inconvenience to users. Furthermore, since water may contain impurities and sediments, these substances can easily accumulate in the internal channels or key components of the mixing valve, leading to blockages. Once blocked, it not only affects the normal flow of water and reduces water output efficiency, but may also cause unstable water temperature, affecting the user experience. On the other hand, when it is necessary to repair, replace parts, or clean the mixing valve, we propose an anti-clogging, easy-to-disassemble suction-type mixing valve. Utility Model Content
[0003] 1. Technical problems to be solved
[0004] The purpose of this application is to provide an anti-clogging, easy-to-disassemble suction-type mixing valve, which solves the technical problems mentioned in the background art. It realizes that the entire mixing valve adopts a threaded connection between multiple components and a detachable installation method. In particular, the mixing valve core and the anti-clogging connector can be threadedly connected to each other in the water distribution pipe, which simplifies the structure and makes it easy to disassemble and install. The mixing valve core and three scrapers are fixedly connected in one piece by the rotating rod. When the rotating rod rotates, the hot and cold water ratio is adjusted. At the same time, the scrapers can rotate in contact with the filter screen surface to clean the impurities and dirt on the filter screen in time, effectively preventing clogging. This active anti-clogging method is different from the traditional passive filtration and greatly improves the technical effect of anti-clogging capability.

A nut 35 is rotatably fitted onto the inner tube 31. The main body of the mixing valve is a T-shaped valve pipe 1, which is integrally formed to firmly connect the two water distribution valves. The mixing valve core 2 and the anti-clogging connector 3 can be easily and detachably installed on both the pipe sleeve 11 and the distribution pipe sleeve 11. The mixing valve core 2 and the anti-clogging connector 3 are connected by a threaded connection, simplifying the structure, ensuring a tight fit between components, and facilitating subsequent disassembly and maintenance. The mixing valve core 2 is mainly framed by an outer tube 21. A locking nut 22 is fixedly installed on the outer tube 21, and a sealing gasket 23 is installed on the locking nut 22. The outer tube 21 rotates... A rotating rod 26 is installed, which is integrally connected to a rotating column 25, a valve core column 27, and three scraper blades 28. This allows the user to directly rotate the rotating column 25, causing the rotating rod 26 to drive the valve core column 27 and the three scraper blades 28 to rotate.

When the mixing valve core 2 and the anti-clogging connector 3 are threadedly connected in the water distribution pipe cylinder 11, sealing gasket 1 23 and sealing gasket 3 34 can be squeezed. Through the tight fit between the sealing gasket and the convex ring pipe opening 12, the sealing performance of both ends of the water distribution pipe cylinder 11 is achieved, preventing water leakage.
[0035] Reference Figure 1 and Figure 4 The outer tube 21 has an internal threaded groove 212 at its bottom end, and the inner tube 31 has an external threaded groove 311 at its upper end that matches and connects with the internal threaded groove 212. A sealing gasket 24 is installed inside the internal threaded groove 212 of the outer tube 21, and the end face of the inner tube 31 abuts against the sealing gasket 24. The inner tube 31 and the outer tube 21 are threaded together, making the connection between the outer tube 21 and the inner tube 31 more stable and precise. The sealing gasket 24 on the end faces of the outer tube 21 and the inner tube 31 further ensures the sealing of the connection between the outer tube 21 and the inner tube 31, preventing water leakage from this point.

The valve core 27 is sealed against the inner wall of the valve cavity 213, which ensures a good seal between the valve core 27 and the valve cavity 213 and prevents water from bypassing the valve core 27 and flowing out directly, thereby improving the accuracy of water flow control. The user can rotate the valve core 27 by rotating the rotating rod 26, so that the overlapping area of the fan-shaped adjustment grooves 271 and the arc grooves 211 can be changed to adjust the ratio of hot and cold water inflow, thereby achieving precise adjustment of the water flow.
[0037] Reference Figure 2 and Figure 3 The water distribution pipe cylinder 11 is provided with an installation cavity 13. The outer pipe 21 and the inner pipe 31 are threadedly installed in the installation cavity 13. The design of the installation cavity 13 provides a stable installation space for the outer pipe 21 and the inner pipe 31, so that they can be accurately installed in the predetermined position and are easy to disassemble and maintain. At the same time, the installation cavity 13 can also protect some components and extend their service life.
[0038] Working principle: When assembling the mixing valve, the two ends of the T-shaped valve pipe 1, the water distribution pipes 11, are connected to the hot water pipe and the cold water pipe respectively. Each end of the water distribution pipe 11 is equipped with a mixing valve core 2 and an anti-clogging connector 3. The outer tube 21 of the mixing valve core 2 and the inner tube 31 of the anti-clogging connector 3 are inserted into the mounting cavity 13 of the water distribution pipe 11. Using two wrenches, the upper lock nut 22 and the lower lock nut 33 are rotated in opposite directions to thread the inner tube 31 onto the outer tube 21. The ports of the inner tube 31 and the outer tube 21 are sealed by a second sealing gasket 24. The two ends of the convex annular pipe openings 12 of the water distribution pipe 11 are sealed by a first sealing gasket 23. The nut 35 of the anti-clogging connector 3 is threadedly connected to the water supply pipe joint. The T-shaped valve... The shower head connection pipe 4 is threaded onto the outlet of pipe 1. The overall design is simple and easy to install and disassemble. The water in the water supply pipe flows into the outer pipe 21 through the inner pipe 31. If there are impurities in the water, they will be blocked by the filter screen 32 on the inner pipe 31. The water can flow into the T-shaped valve pipe 1 through the arc groove 211 of the outer pipe 21 to achieve mixing of cold and hot water. By rotating the rotating column 25, the valve core column 27 and the scraper 28 will rotate as the rotating rod 26 rotates. The ratio of cold and hot water can be adjusted by changing the overlapping area of the fan-shaped adjustment groove 271 and the arc groove 211 on the valve core column 27. It is easy to use. The scraper 28 will rotate against the surface of the filter screen 32 to scrape off the impurities attached to the filter screen 32 and prevent the accumulation of impurities from causing blockage.
