During installation, the cold water channel is connected to the cold water pipe, the hot water channel is connected to the hot water pipe, and the water outlet channel is connected to the water outlet pipe. When in use, the user can control the valve core to move up and down inside the valve body by moving the handle up and down. When the connecting column is aligned with the cold water channel, cold water flows through the cold water channel, passes through the channel formed by the connecting column and the inside of the valve body, and flows into the water outlet channel.

[0015] 2. For the multi-channel switching control valve, the pipeline magnetic sealing ring, the valve body magnetic sealing ring and the valve core magnetic sealing ring are all made of magnetic rubber material. Magnetic rubber is a kind of magnet made by compounding bonded ferrite magnetic powder and synthetic rubber and processed by processes such as extrusion molding, calendering molding, and injection molding, which makes the pipeline magnetic sealing ring, the valve body magnetic sealing ring and the valve core magnetic sealing ring have magnetism while having sealing performance. Moreover, the magnetic poles of the pipeline magnetic sealing ring and the valve body magnetic sealing ring facing the valve core direction are opposite to the magnetic poles of the valve core magnetic sealing ring facing the valve body direction. Therefore, when the user controls the movement of the internal valve core through an external handle, when the connecting column moves to corresponding positions of the cold water channel, the hot water channel, the water outlet channel and the secondary water outlet channel, the two magnetic sealing rings attract each other to help the user fix it, so that the user does not need to constantly apply external force to the handle. When the user finishes using, the valve core is toggled back to the middle position, and the valve core magnetic sealing ring attracts the valve body magnetic sealing ring to fix the valve core. This design simplifies the operation steps, liberates the user's hands, and at the same time ensures the sealing performance of the valve body in the non-working state and the stability during water outlet.

[0023] The following further details the present application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0024] The accompanying drawings in the embodiments of the present utility model: The different types of hatching lines in the figure are not marked according to the national standard, nor are the materials of the components required. It is to distinguish the sectional views of the components in the figure. Please refer to Figures 1-3, a multi-channel switching control valve, comprising a valve body 1. Inside the valve body 1, there is a hollow through-channel. A valve core 2 is installed in the channel. The valve core 2 has the freedom to move up and down inside the valve body 1. The valve core 2 is a cylinder, and in the middle, there is a connecting column 10 with a diameter smaller than that of the valve core 2. The connecting column 10 is fixedly connected to the valve core 2. The connecting column 10 forms a channel inside the valve body 1. Inside the valve body 1, there are designed a cold water channel 701, a hot water channel 702, an outlet auxiliary channel 9, and an outlet channel 703. The outlet auxiliary channel 9 is internally connected to the outlet channel 703. The cold water channel 701 and the hot water channel 702 are located on the same side of the valve body 1, and the outlet channel 703 and the outlet auxiliary channel 9 are located on the other side of the valve body 1. The diameters of the cold water channel 701, the hot water channel 702, the outlet auxiliary channel 9, and the outlet channel 703 are the same as the length of the connecting column 10. The cold water channel 701 and the outlet channel 703 are of concentric circle structure, and the hot water channel 702 and the outlet auxiliary channel 9 are of concentric circle structure. At the connection ports of the cold water channel 701, the hot water channel 702, the outlet auxiliary channel 9, and the outlet channel 703 with the inside of the valve body 1, pipeline magnetic seals 4 are designed and installed. On both surfaces where the valve core 2 is connected to the connecting column 10, valve core magnetic seals 6 are designed and installed. The surface of the valve core magnetic seal 6 facing the valve body 1 and the surface of the pipeline magnetic seal 4 facing the valve core 2 are of opposite polarities. In the middle position at the connection between the valve body 1 and the valve core 2, valve body magnetic seals 11 are embedded. The number of valve body magnetic seals 11 is two, and the distance between them is the same as the length of the connecting column 10. The valve core magnetic seals 6 are embedded in the valve core 2, and the pipeline magnetic seals 4 are embedded in the valve body 1. Both of them and the valve body magnetic seals 11 are made of magnetic rubber material. The outer diameter of the valve core magnetic seal 6 is equal to the diameter of the valve core 2, and the inner diameter of the pipeline magnetic seal 4 is equal to the diameters of the cold water channel 701, the hot water channel 702, the outlet auxiliary channel 9, and the outlet channel 703. The polarity of the valve body magnetic seal 11 facing the valve core 2 is opposite to the polarity of the valve core magnetic seal 6 facing the valve body 1. At both ends of the valve core 2, limit plates 8 are designed and installed. The limit plates 8 are fixedly connected to the valve core 2, and the limit plates 8 are square, and the length of the shortest side is greater than the diameter of the valve core 2. The limit plates 8 are connected to the outer surfaces at both ends of the valve body 1 through springs 3. The springs 3 are concentric with the valve core 2, and the diameter of the springs 3 is greater than the diameter of the valve core 2 and less than the length of the shortest side of the limit plates 8. A handle 5 is designed and connected to the lower limit plate 8.

[0025] Please refer to Figures 4-5, the pipe magnetic seal ring 4, the valve body magnetic seal ring 11 and the valve core magnetic seal ring 6 are all made of magnetic rubber. The magnetic rubber is a soft, elastic and twistable magnet made of bonded ferrite magnetic powder and synthetic rubber through extrusion molding, calendering molding, injection molding and other processes. The pipe magnetic seal ring 4, the valve body magnetic seal ring 11 and the valve core magnetic seal ring 6 have both sealing properties and magnetism, and the magnetic poles of the pipe magnetic seal ring 4 and the valve body magnetic seal ring 11 facing the valve core 2 are opposite to the magnetic poles of the valve core magnetic seal ring 6 facing the valve body 1. Therefore, when the user controls the movement of the internal valve core 2 through the external handle 5, when the connecting column 10 moves to the corresponding positions of the cold water channel 701, the hot water channel 702, the water outlet channel 703 and the water outlet auxiliary channel 9, the magnetic seals of the two attract each other to help the user fix it, so that the user does not need to give external force to the handle 5 all the time. When the user finishes using it, the valve core 2 is turned back to the middle position, and the seal ring of the valve core 2 and the seal ring of the valve body 1 attract each other to fix the valve core 2. This design simplifies the operation steps, frees the hands of the user, and at the same time ensures the sealing performance of the valve body 1 in a non-working state and the stability when discharging water.

[0026] During use, the user can control the valve core 2 to move up and down along the inside of the valve body 1 by toggling the handle 5 up and down. When the connecting column 10 is aligned with the cold water channel 701, cold water passes through the cold water channel 701 and the channel formed by the connecting column 10 and the inside of the valve body 1 and flows into the water outlet channel 703. When the connecting column 10 is aligned with the hot water channel 702, hot water passes through the hot water channel 702 and flows into the water outlet auxiliary channel 9, and then flows into the water outlet channel 703 through the water outlet auxiliary channel 9. This enables a single handle 5 to simultaneously control the outlet of hot and cold water by toggling it, without the need to rotate or replace the water outlet, thereby reducing the difficulty of operation and the manufacturing cost.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
