Multiple wires are mixed together, which is not convenient for later maintenance and wire removal, so a wire management structure 3 is set, and the wire management structure 3 includes a base 31, and the upper right side of the base 31 is movably connected to a flap 32, and a No. 1 wire management groove 33 is provided in the middle of the upper end of the base 31, and the inner diameter of the No. 1 wire management groove 33 is larger than that of the No. 2 wire management groove 34, and two No. 2 wire management grooves 34 are provided on the left side of the No. 1 wire management groove 33, and the terminal 2 The wires dragged out are first arranged into the No. 2 wire management groove 34 at the closest distance, so that a part of the wires arranged together always has an independent path, which is convenient for later wire replacement and withdrawal. Starting from the second closest No. 1 wire management groove 33, the wires are all arranged in the No. 1 wire management groove 33, so that an integrated gas path control element drags out a synthetic wire as a whole, and the No. 1 wire management groove 33 and the No. 2 wire management groove 34 are adapted with a reducing block 35. According to the size of the dragged wire, whether to use the reducing block 35 is selected to ensure that multiple wires can always be close together to increase neatness. The right side of the lower end of the flip cover 32 is provided with a No. 1 arc surface 36, and the No. 1 arc surface 36 is used in conjunction with the No. 1 wire management groove 33 to form a limiting circle, and the left side of the lower end of the flip cover 32 is provided with a No. 2 arc surface 310, and the No. 2 arc surface 310 is used in conjunction with the No. 2 wire management groove 34 to form a limiting circle to prevent the wire from coming out without reason.

[0026] Further, if Figure 2 As shown, an extension plate 37 is provided at the left end of the flip cover 32, and a card slot 38 is provided at the right end of the extension plate 37. A card slot 38 is adapted to fit in a card protrusion 39, and the protrusion 39 is located at the left end of the base 31. Both the extension plate 37 and the protrusion 39 are made of plastic and have a certain deformation ability. The card slot 38 and the protrusion 39 can be fixed together by hand force, so that the flip cover 32 can be opened to take or release the line.

An installation channel 23 is provided inside the micro solenoid valve 2. An armature 24 is provided in the installation channel 23. A movable ejector rod 25 is provided inside the armature 24. After the micro solenoid valve 2 is powered on, a magnetic field is generated by the coil. The magnetic force causes the movable ejector rod 25 inside the armature 24 to expand and contract. When the movable ejector rod 25 blocks the first air hole 12, the air flow path can be cut off. Otherwise, the air flow path is maintained.

[0028] Further, as Figure 4 shown, the right end of the armature 24 is adaptively connected to the connection groove 11, and there is a sealing ring between them to ensure the sealing between the two. A first air hole 12 is provided in the middle of the bottom of the connection groove 11, and a second air hole 13 is provided on the upper side of the connection groove 11.

The gas enters from the intake air duct 15 and surges into the sealed space formed by the first air duct 14, the first air hole 12, the armature 24 and the connection groove 11. Then the gas surges into the outlet air duct 17 through the second air hole 13 and the second air duct 16, and flows through the catheter connected to the outlet air duct 17 to the pneumatic control component that needs to be controlled.

[0030] Further, both ends of the intake air duct 15 penetrate through the front and rear surfaces of the valve body 1. During use, one end of the intake air duct 15 is blocked to prevent air leakage.
