[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Example 1

[0040] As mentioned in the background section, there are technical issues such as... Figures 1-12 As shown, this application proposes an integrated tube cluster split connector for connecting to a multi-channel tube body having multiple internal fluid channels 11. The split connector includes:

[0041] Multiple first connecting portions 21 are provided, each first connecting portion 21 is respectively disposed corresponding to the fluid channel 11, one end of each first connecting portion 21 extends into the fluid channel 11, and its interior has a first flow channel 211 communicating with the fluid channel 11;

[0042] The adapter 22 has a first connecting part 21 on one side, which has a plurality of second flow channels 221 that are connected to the first flow channel 211. The adapter 22 also has a plurality of second connecting parts 23, which have a third flow channel 231 inside, and the third flow channel 231 is connected to the second flow channel 221.

[0043] The outer diameter of the first connecting part 21 is slightly smaller than the inner diameter of the fluid channel 11, so that when the first connecting part 21 is connected to the multi-channel tube 1, the outer wall of the first connecting part 21 is in close contact with the inner wall of the fluid channel 11. The bottom end of the first connecting part 21 has a conical shape, which is wider at the top and narrower at the bottom, facilitating the insertion of the first connecting part 21 into the fluid channel 11. The two ends of the conical shape are respectively connected to the first flow channel and the fluid channel 11. Optionally, the shape of the flow channel is not limited, such as... Figures 9-10 As shown, its cross-section is irregular in shape, such as... Figures 11-12 As shown, its cross-section is circular. Optionally, the second connecting portion 23 is an air nozzle, with its end away from the adapter 22 connected to the independent pipeline 4. For example, the air nozzle can be connected to an air bag in a car seat massage system for inflating the air bag. Figure 12 As shown, when the connected independent pipe 4 is not a regular round pipe, but a more specialized independent pipe 4, the shape of the second connecting part 23 can be changed, depending on the actual situation. Optionally, as... Figure 16 The outer wall of the multi-channel tube 1 is provided with spikes 14 to prevent friction noise between it and other structures.

[0044] When using, such as Figure 7 As shown, the multi-channel tube 1 is connected to the first connecting part 21, and then the independent pipe 4 is connected to the second connecting part 23, realizing multi-channel gas-liquid transmission. Compared with the existing connectors, the volume is reduced, which makes it easier to pass through narrow spaces, improves efficiency, avoids occupying a lot of space, and increases flexibility.

[0045] Furthermore, such as Figure 2 As shown, when both ends of the multi-channel tube 1 are connected to the split connector, both ends are connected to the first connecting part 21 of different split connectors, and both second connecting parts 23 can be connected to the independent pipeline 4.

[0046] In a preferred embodiment, such as Figure 3 As shown, each of the first connecting parts 21 has a barb structure 24 on its outer wall, which is used to fix to the inner wall of the fluid channel 11.

[0047] The number of barb structures 24 outside each first connecting portion 21 is unlimited, but there is at least one. The barb structure 24 includes a vertical portion disposed on the outer wall of the first connecting portion 21, a horizontal portion extending outward from the top of the vertical portion, and an oblique portion connecting the horizontal portion away from the end of the first connecting portion 21 and the bottom end of the vertical portion.

[0048] In a preferred embodiment, there are three first connecting portions 21, and the intersection of the extended axes of the three first flow channels 211 with the first plane forms an equilateral triangle, and the first plane is perpendicular to the extended axis of any of the first flow channels 211.

[0049] The multi-channel tube 1 includes three conduits circumferentially distributed around its centerline, and the distribution of the three first connecting parts 21 is the same as that of the three conduits.

[0050] In a preferred embodiment, the centerline of the multi-channel tube 1 extends in a first direction, each second channel 221 is isolated from the others, the second channel 221 extends in a second direction, the second direction is perpendicular to the first direction, and the end of the second channel 221 away from the first channel 211 is connected to the third channel 231.

[0051] like Figure 4-6 As shown, when the split connector and the multi-channel tube 1 are placed vertically, the first direction is vertical and the second direction is horizontal. The shape of the adapter 22 is not limited, but it can have three non-connected second flow channels 221 inside.

[0052] In a preferred embodiment, the outer wall of the second connecting portion 23 is in the shape of a staggered pagoda to improve the sealing performance of the connection with external pipes.

[0053] like Figure 6 As shown, the outer wall of the second connecting portion 23 includes multiple rings of protrusions distributed along its extension direction, each protrusion having the same outer diameter, and the center of the second connecting portion 23 has a through hole, forming a third flow channel 231.

[0054] In a preferred embodiment, such as Figure 3 As shown, the outer wall of the adapter 22 is provided with a channel opening 25 that communicates with each of the second flow channels 221. The channel opening 25 is used to manufacture the second flow channels 221 during the manufacturing stage.

[0055] During the manufacturing stage, the mold needs to be removed. The cylindrical mold can be taken out through the channel opening 25 to form the second flow channel 221.

[0056] In a preferred embodiment, a sealing member 3 for sealing the channel opening 25 is provided at the channel opening 25; the sealing member 3 is interference-fitted with the channel opening 25.

[0057] like Figure 1 As shown, optionally, the sealing element 3 is a steel ball, which is interference-fitted with the channel opening 25 to seal the channel opening 25. Alternatively, sealing can also be achieved by applying adhesive inside the channel opening 25.

[0058] Furthermore, such as Figures 13-15 To improve the flexibility of insertion, the three conduits at the end of the multi-channel tube 1 away from the first connecting part 21 can be separated. Before separation, the three conduits are connected by connector 13. The three conduits can be separated by tearing open connector 13. In this scenario, a protrusion 12 is provided on the outer wall of the multi-channel tube 1 to prevent the conduits from bending and to prevent abnormal noise caused by friction between the conduits.

[0060] Based on Embodiment 1, this application provides a pneumatic system, including the integrated tube cluster split connector described above, the multi-channel tube body 1 connected to the integrated tube cluster split connector, and an air source component, an air consumption component, and a control component. The air source component and the control component are connected through the multi-channel tube body 1 and the integrated tube cluster split connector, and / or the control component and the air consumption component are connected through the multi-channel tube body 1 and the integrated tube cluster split connector.

[0061] Optionally, the air source component is an air pump, the air consumption component is a massage air bag, and the control component is a control valve body. When an air pump includes multiple air outlets, or includes multiple air pumps with one air outlet, and includes multiple control valve bodies, the multiple air outlets can be connected to the multi-channel tube 1 and connected to the multiple control valve bodies through the second connecting part 23 of the integrated tube cluster split connector. When there are multiple massage air bags and multiple control valve bodies, the control valve body is connected to the multi-channel tube 1 and communicates with the massage air bag through the second connecting part 23.

[0062] In a preferred embodiment, the fluid channel 11 of the multi-channel tube 1 can be partially separated into independent pipelines to facilitate connection to external components.

[0063] like Figure 13 As shown, the multi-channel tube 1 includes multiple tubes, each of which has a fluid channel 11. This design can be connected to multiple distributed air sources, multiple control valves, or multiple air-using components, thus avoiding limitations in its use.
