[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1 , 2As shown, the utility model discloses a circuit-gas composite joint, comprising a conductive slip ring 1 and a gas guide assembly 2. The conductive slip ring 1 comprises a first conductive element 11 and a second conductive element 12, wherein one of the first conductive element 11 and the second conductive element 12 is a stator and the other is a rotor, and the two can rotate relative to each other and always contact each other for conduction.

The first conductive element 11 and the second conductive element 12 can be in contact with each other through the conductive ring 125 and the conductive brush 126 for electrical conduction. In this embodiment, the first conductive element 11 is a stator, the second conductive element 12 is a rotor, the conductive brush 126 is disposed on the first conductive element 11, and the conductive ring 125 is disposed on the second conductive element 12.

[0023] The gas guide assembly 2 includes a relatively rotatable gas guide shaft 21, a gas guide sleeve 22, and a sheet-shaped isolation ring 25. The cross-section of the gas guide shaft 21 parallel to its own axis is in a convex shape. The gas guide shaft 21 is provided with a wire through hole 212 and a plurality of first gas guide channels 211. The wire through hole 212 is located at the center of the gas guide shaft 21 and is provided through the axial direction of the gas guide shaft 21. The gas guide sleeve 22 is sleeved on the outside of the gas guide shaft 21 and is located at a portion of the gas guide shaft 21 with a smaller diameter. A plurality of second gas guide channels 221 are provided in the gas guide sleeve 22. The isolation ring 25 is also sleeved on the outside of the gas guide shaft 21 and is provided at a portion of the gas guide shaft 21 with a smaller diameter. The isolation ring 25 is located between the ends of the gas guide shaft 21 and the gas guide sleeve 22 and separates the two from each other. The air guide shaft 21 is provided with a clamping hole 214 , which is connected to the wire through hole 212 . One end of the first conductive element 11 provided with a first wire outlet hole 111 is clamped and fixed in the clamping hole 214 .

[0024] A plurality of annular grooves 213 are provided on the outer side of the gas guide shaft 21 and / or the inner side of the gas guide sleeve 22, and sealing rings 24 are fixedly provided on both sides of the annular grooves 213. The gas guide shaft 21 and the gas guide sleeve 22 are sealed and connected via the sealing rings 24, and a plurality of annular channels 23 are formed by the annular grooves 213. The number and position of the annular channels 23 correspond to the first gas guide channel 211 and the second gas guide channel 221 one by one, and the first gas guide channel 211 and the second gas guide channel 221 are connected to each other via the annular channels 23.

[0025] In the composite joint, the gas guide sleeve 22, the first conductive element 11, the second conductive element 12 are coaxially arranged with the gas guide shaft 21, the annular channel 23 is arranged with the axis of the gas guide shaft 21 as the center, the gas guide shaft 21 and the first conductive element 11 are fixedly connected to each other, the gas guide sleeve 22 and the second conductive element 12 are fixedly connected to each other, and the first wire outlet hole 111 on the first conductive element 11 is opposite to the wire through hole 212 on the gas guide shaft 21.

[0026] When the composite joint is in use, a circuit structure such as an external cable 5 can be connected through the conductive brush 126 on the first conductive element 11 and the conductive ring 125 on the second conductive element 12. After the connection, components such as the cable 5 electrically connected to the conductive brush 126 on the first conductive element 11 can be led out through the first outlet hole 111 and the wire through hole 212; at the same time, the air path structure can be connected through the first air guide channel 211, the annular channel 23, and the second air guide channel 221 that are connected in sequence, so as to realize the integrated connection between the circuit structure and the air path structure. On this basis, when any one of the air guide shaft 21, the air guide sleeve 22, the first conductive element 11, and the second conductive element 12 is driven to rotate, the remaining components can rotate accordingly or change positions relative to each other. During the rotation process, on the one hand, the conductive slip ring 1 can continuously contact and conduct electricity through the conductive ring 125 and the conductive brush 126, and then continuously connect to the circuit structure, and the external cable 5 at the first conductive element 11 and other components are led out from the wire through hole 212, which is not affected by the rotation and is not easy to be entangled. On the other hand, the air guide component 2 can be continuously guided through the annular channel 23, and then continuously connect to the air path structure. The combination of the two makes the composite joint suitable for use in environments that require unlimited continuous rotation.

[0027] In the conductive slip ring 1, a bearing 127 is provided between the first conductive element 11 and the cylindrical portion 121 of the second conductive element 12, and the first conductive element 11 and the second conductive element 12 are rotatably connected to each other through the bearing 127 to ensure smooth rotation. In addition to the cylindrical portion 121, the second conductive element 12 is also provided with a protective portion 122, which is fixedly connected to the outside of the cylindrical portion 121 and covers the conductive ring 125 or the conductive brush 126 provided on the cylindrical portion 121. In this embodiment, the protective portion 122 covers the conductive ring 125 provided on the cylindrical portion 121, and while playing a protective role, it does not affect the external circuit structure of the conductive ring 125. The protective portion 122 and the cylindrical portion 121 together form a wire collecting cavity 124, and a second wire outlet hole 1211 is provided at one end of the cylindrical portion 121 away from the air guide component 2. The wire collecting cavity 124 and the second wire outlet hole 1211 are interconnected, and components such as the cable 5 electrically connected to the conductive ring 125 can be collected in the wire collecting cavity 124 and led out through the second outlet hole, thereby avoiding entanglement and avoiding affecting the rotation between the first conductive element 11 and the second conductive element 12.

[0028] In addition, the outer surface of the protective portion 122 extends outward to form an extension portion 123, and a support seat 3 is provided between the extension portion 123 and the air guide sleeve 22, and they are fixedly connected to each other through the support seat 3; the extension portion 123 is annular as a whole, and the cross-sectional shape of the support seat 3 parallel to the axial direction of the wire through hole 212 is in the shape of a "J", which can stably support the extension portion 123, and then firmly connect the second conductive element 12 to the air guide sleeve 22.

[0029] The outer cover of the conductive slip ring 1 is provided with a protective cover 4, which is provided on the side of the conductive slip ring 1 away from the air guide component 2 and is fixedly connected to the second conductive element 12, so as to protect the conductive slip ring 1. A third wire outlet hole 41 is provided through the protective cover 4, and the position of the third wire outlet hole 41 is opposite to the second wire outlet hole 1211. When in use, the cable 5 electrically connected to the conductive ring 125 can be led out through the wire collecting cavity 124, the second outlet hole, and the third wire outlet hole 41 in sequence, and it is not easy to get entangled after being led out.

[0030] In short, the circuit-gas circuit composite joint is practical and can integrate the circuit structure and the gas circuit structure, and can be applied to the usage scenario of unlimited continuous rotation. It has a wide range of applications. The circuit structure and the gas circuit structure after docking have high integration, strong aesthetics, and occupy less space.
