Description

Technical Field

[0001] This utility model relates to the field of switcher technology, and in particular to a spring-loaded multi-channel switcher. Background Technology

[0002] A multi-channel switcher is used to allow fluid to enter through a single inlet and exit through a designated outlet channel. It is commonly used in smart toilets and dental flossers to achieve different cleaning effects on different areas.

[0003] However, this technical solution requires ensuring that when one outlet is opened, the other channels remain closed. Therefore, the sealing performance between the channel switching turntable and the outlet is particularly important. Regardless of whether a sealing ring or a plane-to-plane seal is used, the sealing ring or plane will wear down after long-term use. This will cause fluid to flow out from different outlet channels simultaneously, affecting the design function of the multi-channel switcher. Utility Model Content

[0015] The beneficial effects of this utility model are as follows: This utility model provides a spring-loaded multi-channel switcher, which, compared with the prior art, has at least the following technical effects: 1. By setting an elastic element on the connector between the first and second connecting parts, the elastic force of the elastic element pushes the multi-outlet housing and the channel switching turntable closer together, so that the mating surfaces of the multi-outlet housing and the channel switching turntable can be firmly attached together. Even when the channel switching turntable wears out due to long-term rotation, it can still tightly fit the plane of the multi-outlet housing, achieving a long-term sealing effect and significantly extending the service life of the multi-channel switcher. 2. The elastic element is a spring or rubber ring, which can drive the multi-outlet housing and the channel switching turntable closer together through its own stress to ensure the sealing effect. 3. The connector is a screw, which can connect the multi-outlet housing and the channel switching turntable together. One end of the spring abuts against the screw head to provide a thrust towards the multi-outlet housing, and the other end abuts against the multi-outlet housing to provide a thrust towards the channel switching turntable, thus making the multi-outlet housing and the channel switching turntable press against each other to maintain the sealing effect. 4. The connecting hole is a three-stage stepped hole, which facilitates the screw-limited connection between the multi-outlet housing and the channel switching turntable, while also providing a contact point for the elastic element, enabling it to drive the multi-outlet housing and the channel switching turntable to abut against each other and maintain a sealing effect. 5. A first sealing ring is provided to further ensure the sealing effect between the multi-outlet housing and the channel switching turntable, providing double protection. 6. A second sealing ring is provided at the connection between the multi-outlet housing and the inlet housing, providing a sealing effect. Since the two do not rotate relative to each other, there is no need to consider rotational wear. 7. A synchronous turntable is also provided between the motor's output shaft and the channel switching turntable. The synchronous turntable has a trigger point detection switch. Through design calculations, when the protrusion touches the position detection switch, the circular hole on the channel switching turntable aligns perfectly with one of the outlets on the multi-outlet housing. At this time, the position detection switch transmits a signal to the main board program, causing the motor to stop rotating. After a set time, the motor continues to rotate until the next protrusion structure on the synchronous turntable touches the position detection switch, and so on, realizing the function of multiple outlet channels opening in turn.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figures 1 to 3 A spring-loaded multi-channel switcher includes a multi-outlet housing 1 and an inlet housing 2, which are connected together. A channel switching turntable 3 is installed within the multi-outlet housing 1 and the inlet housing 2. The channel switching turntable 3 is connected to a motor 4 that drives its rotation. The multi-outlet housing 1 has a first connecting part, and the channel switching turntable 3 has a second connecting part. A connecting member 5 connects the first connecting part and the second connecting part. The connecting member 5 has an elastic element 6, which is used to push the multi-outlet housing 1 and the channel switching turntable 3 to abut against each other. By setting the elastic element 6 on the connecting member 5 between the first and second connecting parts, the elastic force of the elastic element 6 pushes the multi-outlet housing 1 and the channel switching turntable 3 closer together, so that the mating surfaces of the multi-outlet housing 1 and the channel switching turntable 3 can be firmly attached together. Even when the channel switching turntable 3 wears out due to long-term rotation, it can still tightly fit 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.

[0022] Please see Figures 1 to 3 Preferably, the elastic element 6 is a spring or a rubber ring, and the spring or the rubber ring is disposed on the connecting member 5. The elastic element 6, being a spring or a rubber ring, can drive the multi-outlet housing 1 and the channel switching turntable 3 to come closer together through its own stress to ensure a sealing effect.

[0023] Please see Figures 1 to 3Preferably, the first connecting part is a connecting hole, and the second connecting part is a connecting shaft; or, the first connecting part is a connecting shaft, and the second connecting part is a connecting hole; the connecting shaft is inserted into the connecting hole, and the connecting member 5 is fixed on the connecting shaft; the connecting member 5 is provided with a limiting part, one end of the spring or rubber ring abuts against the limiting part, and the other end abuts against the inner end face of the connecting hole. The connecting member 5 is a screw, the screw head is the limiting part, one end of the spring or rubber ring abuts against the screw head, and the screw is locked onto the connecting shaft. The connecting member 5 is a screw, which can connect the multi-outlet housing 1 and the channel switching turntable 3 together. One end of the spring abuts against the screw head to provide a thrust towards the multi-outlet housing 1 to the channel switching turntable 3, and the other end abuts against the multi-outlet housing 1 to provide a thrust towards the channel switching turntable 3, thus causing the multi-outlet housing 1 and the channel switching turntable 3 to abut together, achieving the effect of maintaining a sealing effect.

[0024] Please see Figures 1 to 3 Preferably, the connecting hole is a three-section stepped hole. The inner end face of the section with the largest diameter abuts against the screw head, the inner end face of the middle section abuts against the end face of the spring or the rubber ring, and the connecting shaft passes through the connecting hole from the section with the smallest diameter. The three-section stepped hole facilitates the screw's positioning and connection between the multi-outlet housing 1 and the channel switching turntable 3, while also providing a contact point for the elastic element 6, enabling it to drive the multi-outlet housing 1 and the channel switching turntable 3 to abut against each other and maintain a sealing effect.

[0025] Please see Figure 1 Preferably, a first sealing ring 7 is provided between the end face of the spring and the inner end face of the middle section of the connecting hole. The first sealing ring 7 further ensures the sealing effect between the multi-outlet housing 1 and the channel switching turntable 3, providing double protection. Preferably, the multi-outlet housing 1 and the inlet housing 2 are connected by screws, and a second sealing ring 8 is provided at the connection between the multi-outlet housing 1 and the inlet housing 2. The second sealing ring 8 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 rotational wear.

[0026] Please see Figures 1 to 3Preferably, a synchronous turntable 9 is also provided on the shaft connecting the motor 4 and the channel switching turntable 3. The synchronous turntable 9 has a trigger point. A position detection switch 10 is connected to the outside of the inlet housing 2. The position detection switch is located on the path traversed by the trigger point, and the trigger point can trigger the position detection switch 10. A synchronous turntable 9 is also provided between the output shaft of the motor 4 and the channel switching turntable 3. The synchronous turntable 9 has a trigger point that triggers the detection switch 10. Through design calculations, when the protrusion touches the position detection switch 10, the circular hole on the channel switching turntable 3 is aligned with one of the outlets on the multi-outlet housing 1. At this time, the position detection switch 10 will transmit a signal to the main board program to stop the motor 4 from rotating. After a set time of operation, the motor 4 continues to rotate until the next protrusion structure on the synchronous turntable 9 touches the position detection switch 10. This process is repeated to realize the function design of multiple outlet channels being opened in turn.

[0027] Please see Figures 1 to 3 Preferably, the channel switching turntable 3 has a D-shaped hole at the end opposite to the second connecting part, and the rotating shaft of the motor 4 is a D-shaped shaft that passes through the D-shaped hole. A clearance hole is provided on the inlet housing 2 at a position opposite to the D-shaped hole to facilitate the connection between the D-shaped shaft and the D-shaped hole.

[0029] The inlet housing 2 has an inlet structure for connecting the fluid source pipe; the D-shaped shaft on the drive motor 4 is connected to the synchronous turntable 9, which is connected to the channel switching turntable 3. When the motor 4 rotates, it simultaneously drives the synchronous turntable 9 and the channel switching turntable 3 to rotate together; the position detection switch 10 can be a tactile switch, an infrared sensor switch, or a Hall switch, used to detect and control the opening of a certain channel; the first sealing ring 7, the second sealing ring 8, and the third sealing ring 11 are used for sealing between the multi-outlet housing 1 and the channel switching turntable 3, between the inlet housing 2 and the multi-outlet housing 1, and between the inlet housing 2 and the channel switching turntable 3, respectively; the inlet housing 2 has multiple channel outlets, and the channel switching turntable 3 has a single round hole. The spring force installed in the connecting hole makes the two come close to each other, so that the abutting surfaces fit together for sealing; when the single hole on the channel switching turntable 3 is aligned with the set outlet, the trigger point on the synchronous turntable 9 triggers the signal of the position detection switch 10, and the motor 4 stops rotating.
