[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figures 1 to 5 A magnetic multi-channel switcher includes a multi-outlet housing 1 and an inlet housing 2, which are connected together. An outlet switching turntable 3 is rotatably mounted within the multi-outlet housing 1 and the inlet housing 2. The outlet switching turntable 3 is connected to a motor 4 that drives its rotation. A first magnetic element 5 is provided on the multi-outlet housing 1, and a second magnetic element 6 is provided in the outlet switching turntable 3. The first magnetic element 5 and the second magnetic element 6 attract each other, driving the end face of the outlet switching turntable 3 to abut against the inner end of the multi-outlet housing. The mutual attraction of the first magnetic element 5 and the second magnetic element 6 pushes the multi-outlet housing 1 and the switching turntable closer together, ensuring that the mating surfaces of the multi-outlet housing 1 and the switching turntable are firmly attached. Even when the switching turntable wears down due to long-term rotation, it can still tightly adhere to the plane of the multi-outlet housing 1, achieving a long-term sealing effect and significantly extending the service life of the multi-channel switcher.

[0024] Please see Figures 1 to 3 , Figure 5 Preferably, the first magnetic attractor 5 is a magnet, and the second magnetic attractor 6 is a magnet; or, the first magnetic attractor 5 is a magnet, and the second magnetic attractor 6 is a metal that can be attracted by a magnet; or, the second magnetic attractor 6 is a magnet, and the first magnetic attractor 5 is a metal that can be attracted by a magnet. The first magnetic attractor 5 and the second magnetic attractor 6 are magnets or metals that can be attracted by a magnet. They are brought closer together by magnetic force, thereby causing the multi-outlet housing 1 and the inlet housing 2 to come closer together, ensuring a sealing effect between them. The metal can be iron, cobalt, or nickel.

[0025] Please see Figures 1 to 3 , Figure 5 Preferably, the multi-outlet housing 1 is provided with multiple first magnetic suction elements 5 at positions avoiding the outlets, and the outlet switching turntable 3 is provided with multiple second magnetic suction elements 6 at positions avoiding the water outlet holes. The presence of multiple first magnetic suction elements 5 and multiple second magnetic suction elements 6 ensures sufficient attraction when they rotate relative to each other, allowing the multi-outlet housing 1 and the inlet housing 2 to remain in contact and maintain a sealing effect.

[0026] Please see Figures 1 to 3 , Figure 5 Preferably, the multi-outlet housing 1 has multiple first mounting slots, in which the first magnetic element 5 is installed; the outlet switching turntable 3 has multiple second mounting slots, in which the second magnetic element 6 is installed. The first mounting slot is located on the side of the multi-outlet housing 1 facing away from the outlet switching turntable 3, and the second mounting slot is located on the side of the outlet switching turntable 3 facing or facing away from the multi-outlet housing 1; or, the second mounting slot is located on the side of the outlet switching turntable 3 facing away from the multi-outlet housing 1, and the first mounting slot is located on the side of the multi-outlet housing 1 facing or facing away from the outlet switching turntable 3. The first magnetic element 5 and the second magnetic element 6 are spaced apart by the multi-outlet housing 1 and the outlet switching turntable 3, so that the attraction between them can act on the multi-outlet housing 1 and the outlet switching turntable 3 to ensure a sealing effect.

[0027] Please see Figures 1 to 3 , Figure 5 Preferably, when the first mounting groove is opposite to the outlet switching turntable 3, the first magnetic member 5 does not protrude from the first mounting groove; when the second mounting groove is opposite to the multi-outlet housing 1, the second magnetic member 6 does not protrude from the second mounting groove. Ensuring that the first magnetic member 5 does not protrude from the first mounting groove or the second magnetic member 6 does not protrude from the second mounting groove helps avoid interference between the first magnetic member 5 and the second magnetic member 6 and the rotation of the outlet switching turntable 3, thus ensuring a sealing effect when the multi-outlet housing 1 and the outlet switching turntable 3 rotate relative to each other.

[0028] Please see Figures 1 to 5 Preferably, a first sealing ring 7 is provided at the connection between the multi-outlet housing 1 and the inlet housing 2, and a locking screw is provided between the multi-outlet housing 1 and the inlet housing 2. The first sealing ring 7 at the connection between the multi-outlet housing 1 and the inlet housing 2 provides a sealing effect. Since the two do not rotate relative to each other, there is no need to consider the problem of rotational wear.

[0029] Please see Figures 1 to 5Preferably, a synchronous turntable 8 is provided between the outlet switching turntable 3 and the output shaft of the motor 4. The synchronous turntable 8 is located outside the inlet housing 2 and has a trigger part.

When the trigger part on the synchronous turntable 8 touches the position detection switch 9, the water outlet hole on the outlet switching turntable 3 is aligned with one of the outlets on the multi-outlet housing 1. At this time, the detection switch 9 transmits a signal to the main board program, causing the motor 4 to stop rotating. After a set time of operation, the motor 4 continues to rotate until the next trigger part on the synchronous turntable 8 touches the position detection switch 9. This process is repeated to realize the function of opening multiple outlet channels in turn.

[0030] Please see Figures 1 to 5 Please see Figures 1 to 5 Preferably, the end face of the outlet switching turntable 3 facing away from the multi-outlet housing 1 has a connecting portion, and the end of the synchronous turntable 8 facing the outlet switching turntable 3 has a plug-in portion, which is inserted into the connecting portion. The end of the synchronous turntable 8 facing away from the outlet switching turntable 3 has a D-shaped hole, and the output shaft of the motor 4 is D-shaped and inserted into the D-shaped hole.
