[0057] ​This invention provides an outlet 12 and multiple inlets 11 on the side of a switching valve. The switching valve controls the connection and disconnection between the outlet 12 and the multiple inlets 11. Various detergents can be dispensed through the switching valve, eliminating the need for multiple detergent dispensing pumps. This achieves multi-purpose functionality with a single valve, resulting in a simple structure, small footprint, and low cost. Furthermore, the multiple inlets 11 and outlets 12 are spaced apart along the circumferential direction on the side of the switching valve, ensuring a smoother dispensing path without dead angles and reducing detergent residue inside the switching valve.

[0058] In the invention, the liquid outlet 12 may be connected to each of the plurality of liquid inlets 11 respectively, or the liquid outlet 12 may be connected to two or more of the plurality of liquid inlets 11 simultaneously.

[0059] like Figures 2 to 7 As shown, the switching valve includes a valve body 1 and a valve core 2.

[0060] The outlet 12 and multiple inlets 11 are spaced apart along the circumferential direction on the side of the valve body 1. The valve core 2 is rotatably disposed in the valve body 1 along the circumferential direction. The outer peripheral wall of the valve core 2 is rotatably sealed to at least part of the inner peripheral wall of the side of the valve body 1 to close the multiple inlets 11. The outer peripheral wall of the valve core 2 is provided with a through inlet 231, which allows the valve core 2 to selectively connect to or disconnect from one of the multiple inlets 11 when it rotates.

[0061] In this invention, an inlet 231 is provided on the outer peripheral wall of the valve core 2. By controlling the rotation of the valve core 2, the inlet 231 of the valve core 2 is connected to one of the liquid inlets 11, allowing water or detergent to enter. By connecting the inlet 231 of the valve core 2 to multiple liquid inlets 11, various detergents or water can be added separately. The structure is simple and the operation and control are simple.

[0062] The outer peripheral wall of the valve core 2 can be rotatably and sealingly connected to a portion of the inner peripheral wall of the valve body 1, or it can be rotatably and sealingly connected to all of the inner peripheral walls of the valve body 1.

[0063] The valve body 1 has a cavity, and the valve core 2 is rotatably disposed within the cavity of the valve body 1. Preferably, the cavity within the valve body 1 is cylindrical. The liquid outlet 12 and the plurality of liquid inlets 11 are evenly spaced on the outer peripheral wall of the cylinder.

[0064] The switching valve also includes a rotating shaft 3. The rotating shaft 3 is rotatably and sealingly inserted into one end of the valve body 1. The rotating shaft 3 is connected to the valve core 2 and is used to drive the valve core 2 to rotate within the valve body 1.

[0065] Furthermore, the detergent switching and dispensing device also includes a motor 4, which is driven by the rotating shaft 3 to drive the rotating shaft 3 to rotate the valve core 2. The motor 4 is connected to the switching valve via a connector.

[0066] Preferably, the motor 4 is a stepper motor 4, which can control the rotating shaft 3 to rotate within a preset angle range.

[0067] The valve body 1 has a mounting hole at one end. The rotating shaft 3 can be directly and sealingly connected to the mounting hole of the valve body 1 via a sealing ring. Alternatively, the rotating shaft 3 can be assembled and connected to other structures on the valve core 2, and these other structures can be directly and sealingly connected to the mounting hole of the valve body 1 via sealing rings, for example, the rotating shaft 3 can be inserted into other structures.

[0068] like Figures 3 to 6 As shown, the valve body 1 has a liquid inlet channel connecting the inlet 231 and the outlet 12. Preferably, when the inlet 231 is rotated to connect with either the inlet 11, the inlet 231 also connects with the outlet 12 of the valve body 1.

[0069] Furthermore, the valve core 2 includes a shaft seat 21, a support seat 22, and an outer peripheral plate 23.

[0070] One axial end of the bearing seat 21 is connected to the rotating shaft 3. The support seat 22 extends radially outward from the outer peripheral wall of the bearing seat 21. The inner peripheral wall of the outer peripheral plate 23 is connected to the outer peripheral wall of the support seat 22, and the outer peripheral wall of the outer peripheral plate 23 is in contact and sealed with the inner peripheral wall of the valve body 1. The inlet 231 is disposed through the outer peripheral plate 23.

[0071] By setting an outer peripheral plate 23, the present invention can achieve contact sealing between the outer peripheral plate 23 and the inner peripheral wall of the valve body 1, blocking multiple liquid inlets 11. Furthermore, when the inlet 231 on the outer peripheral plate 23 is rotated to be opposite to the liquid inlet 11, the liquid inlet 11 is connected to the liquid inlet channel, thereby enabling liquid to enter the valve body 1.

[0072] The outer peripheral plate 23 is also provided with an outlet 232. The outlet 232 is disposed through the outer peripheral plate 23 and communicates with the inlet 231, and is used to communicate with the outlet 12 when the inlet 231 is connected to any liquid inlet 11.

[0073] Preferably, the outer peripheral plate 23 is a circular outer peripheral plate 23 or an outer peripheral plate 23 extending in an arc shape. The outlet 232 is an arc-shaped notch provided on the outer peripheral plate 23 of the valve core 2.

The liquid enters the inlet 231 of the valve core 2 through the selected liquid inlet 11, flows through the liquid inlet channel to the outlet 232, and is discharged from the liquid outlet 12 of the valve body 1.

[0075] The angle formed between the two ends of the outer peripheral plate 23 extending in the direction of extension and the axis of the bearing seat 21 is greater than or equal to the maximum angle formed between any two of the plurality of liquid inlets 11 and the axis of the bearing seat 21.

[0076] Preferably, the angle formed by the two ends of the outlet 232 extending in the direction of extension and the axis of the bearing seat 21 is greater than the angle formed by the two ends of the inlet 231 extending in the direction of extension and the axis of the bearing seat 21.

[0077] The angle formed by the two ends of the outlet 232 extending in the direction of extension and the axis of the bearing 21 is greater than or equal to the maximum angle between the plurality of liquid inlets 11.

[0078] The minimum included angle formed by the inlet 231, the outlet 232 and the axis of the bearing 21 is less than or equal to the minimum included angle formed by one of the plurality of inlets 11, the outlet 12 and the axis of the bearing 21.

[0079] The plurality of liquid inlets 11 are evenly spaced along the circumferential direction at the top of the side of the valve body 1. The liquid outlet 12 is located at the bottom of the side of the valve body 1. The liquid outlet 12 and the plurality of liquid inlets 11 of the valve body 1 are provided with outwardly extending connectors.

[0080] Preferably, the two axial ends of the outer peripheral plate 23 are in contact with and sealed to the inner sidewalls of the two ends of the valve body 1, which can ensure that the outer peripheral plate 23 of the valve core 2 is positioned opposite to the liquid inlet 11, thereby improving the liquid inlet sealing performance of the valve body 1.

[0081] Furthermore, the liquid inlet channel includes a first liquid inlet channel 221 and a second liquid inlet channel 222.

[0082] The first liquid inlet channel 221 is disposed on the support base 22 and communicates with the inlet 231. The second liquid inlet channel 222 is disposed on the support base 22 and communicates with the outlet 232. The first liquid inlet channel 221 and the second liquid inlet channel 222 are connected.

[0083] One implementation plan is, as follows: Figures 3 to 5 As shown, there is a gap between the inner sidewalls of the two ends of the valve core 2 that are opposite to the valve body 1. The first liquid inlet channel 221 and the second liquid inlet channel 222 are respectively connected to the gap.

[0084] Liquid enters the gap through the inlet port 11 and the first liquid inlet channel 221, and then is discharged through the second liquid inlet channel 222 and the outlet port 12.

[0085] In a preferred embodiment, a gap is also provided between the other end of the shaft seat 21 and the end of the valve body 1, so that liquid can quickly enter the second liquid inlet channel 222 from the first liquid inlet channel 221.

[0086] In a specific embodiment, as shown in Figures 3 to 4 , Figures 3 to 4 the different liquid inlet ports 11 are in communication with the inlet port 231.

[0087] The support seat 22 is a plurality of support arms arranged along the outer circumferential direction on the outer circumferential wall of the shaft seat 21. The inlet port 231 and the outlet port 232 are arranged on the outer circumferential plate 23 between two adjacent support arms, respectively, and the first liquid inlet channel 221 and the second liquid inlet channel 222 are formed between the two adjacent support arms, respectively, and are in communication with the gap.

[0088] Preferably, the support arms are connected to the outer circumferential wall or the shaft seat 21 at one end with a rounded corner to prevent residual detergent.

[0096] Further, the outer peripheral wall of the shaft seat 21 is provided with an annular protrusion, which decreases from the connection between the shaft seat 21 and the support seat 22 to both ends of the shaft seat 21 in the axial direction, facilitating the smooth discharge of liquid through the shaft seat 21 and preventing liquid from remaining on the valve core 2.

[0097] Further, the inner side wall of the end of the valve body 1 is provided with a limiting block 13 for abutting against the inner side wall of the second liquid inlet channel 222 to limit the rotation of the valve core 2 within a predetermined angle, so that the outlet 232 communicates with the liquid outlet 12, and the inlet 231 selectively communicates with the liquid inlet 11. The limiting block 13 is arranged opposite to the liquid outlet 12.
