When the air pressure in the sealed chamber reaches a level sufficient to fit the elastic rubber film with the first pipe and the second pipe, the first contact piece connects the second contact piece with the third contact piece to form a passage. At this time, the LED lamp bead lights up, allowing the operator to know that the inflation volume has reached the minimum standard.

One end of the first pipe 2 and the second pipe 3 are fixedly connected with a connecting joint 12 matching the connecting ring 9. The connecting joint 12 is inlaid with a first permanent magnet 14. Both sides of the connecting ring 9 are inlaid with second permanent magnets 13 corresponding to the first permanent magnet 14 on the connecting joint 12. The first permanent magnet 14 and the second permanent magnet 13 are mutually attractive magnets, so that the first pipe 2 and the second pipe 3 can pass through the openings 8 on both sides of the shell 1 respectively and then be magnetically attracted to both sides of the connecting ring 9 through the connecting joint 12.

[0029] By providing the first permanent magnet 14 and the second permanent magnet 13 , during installation, it is only necessary to insert the connecting joint 12 of the pipe into the connecting ring 9 in the housing 1 , and the pipe can be quickly installed by magnetic attraction, thereby greatly improving the installation efficiency.

[0030] The number of the first permanent magnets 14 is not less than three, and the plurality of first permanent magnets 14 are arranged at equal angles with the axis of the connecting joint 12 as the center.

[0031] The diameter of the opening 8 is larger than the diameter of the connecting ring 9 , and the diameters of the first pipe 2 and the second pipe 3 are both smaller than the diameter of the connecting ring 9 .

[0033] In some embodiments, Figure 4-5As shown, it also includes a sealing mechanism for improving the sealing between the connecting joint 12 and the connecting ring 9, the sealing mechanism includes an elastic rubber membrane 4, a communicating air hole 11, an inflation tube 6, an air release tube 7, and an air pump, the elastic rubber membrane 4 is set to a trumpet shape, the end of the elastic rubber membrane 4 with a smaller diameter matches the connecting ring 9, and the end of the elastic rubber membrane 4 with a larger diameter matches the opening 8 of the shell 1, one end of the elastic rubber membrane 4 is fixedly connected to the outside of the connecting ring 9, and the other end of the elastic rubber membrane 4 is fixedly connected to the opening 8, so that a sealed chamber is formed between the elastic rubber membrane 4, the connecting ring 9, the fixing plate 10 and the shell 1, and the fixing plate 10 is provided with a communicating air hole 11, so that the sealed chambers on both sides of the fixing plate 10 are connected An inflation tube 6 and an air-deflation tube 7 are fixedly connected to the top of the shell 1. Both the inflation tube 6 and the air-deflation tube 7 are connected to the sealed chamber inside the shell 1. The air pump can inflate the sealed chamber through the inflation tube 6 to increase the air pressure in the sealed chamber. When the air pressure in the sealed chamber increases, the elastic rubber membrane 4 is deformed under the action of the air pressure, so that the joints between the elastic rubber membrane 4 and the connecting joint 12 and the connecting ring 9 are completely covered, thereby preventing leakage at the joints. At the same time, as the air pressure continues to rise, the elastic rubber membrane 4 will continue to deform until it fits with the first pipe 2 and the second pipe 3. At this time, the elastic rubber membrane 4 can provide a large amount of friction, thereby further preventing the first pipe 2 and the second pipe 3 from falling off the connecting ring 9.

The second contact piece 18, the battery 17, the LED lamp bead 16, and the third contact piece 19 are connected in sequence by wires, and when the air pressure in the sealed chamber rises, the piston block 24 rises under the action of the air pressure, and the piston block 24 drives the lifting plate 21 to rise through the push rod 22. When the air pressure in the sealed chamber reaches a level sufficient to fit the elastic rubber membrane 4 with the first pipe 2 and the second pipe 3, the first contact piece 20 connects the second contact piece 18 and the third contact piece 19 to form a passage. At this time, the LED lamp bead 16 lights up, which can let the operator know that the inflation volume has reached the minimum standard.

[0037] By setting the prompt device 5, when the air pressure in the sealed chamber rises, the piston block 24 rises under the action of the air pressure, and the piston block 24 drives the lifting plate 21 to rise through the push rod 22. When the air pressure in the sealed chamber reaches a level sufficient to fit the elastic rubber membrane 4 with the first pipe 2 and the second pipe 3, the first contact piece 20 connects the second contact piece 18 and the third contact piece 19 to form a passage.
