The left end of the switching component 6 can be installed and disassembled with the delivery pipe 4 through the sealing component 7. The sealing component 7 can facilitate the assembly and disassembly of the delivery pipe 4 and the cylindrical tube 63, and can improve the sealing effect between the delivery pipe 4 and the cylindrical tube 63. The left end of the delivery pipe 4 is fixedly connected to the refrigerant filling machine 5, and the refrigerant in the cylindrical tube 63 is transported to the refrigerant filling machine 5 through the delivery pipe 4. Through the refrigerant filling machine 5, refrigerant is filled during the production of the air conditioner.

[0033] Reference Figure 1-Figure 3 The switching assembly 6 includes a diverter box 61, and the inner wall of the diverter box 61 is rotatably connected to a rotating box 62. Through the rotation effect of the rotating box 62, the through holes can correspond to the three groups of connecting pipes 3 respectively.

The outer wall of the cylindrical tube 63 is fixedly connected to a fixed block 64. The fixing effect of the fixed block 64 prevents the fixed block 64 from falling off. The left side of the diverter box 61 is fixedly connected to a fixing ring 67. Through the fixing effect of the fixing ring 67, the fixing ring 67 is prevented from falling off.

[0034] Reference Figure 3 and Figure 4 The sealing assembly 7 includes a rotating ring 71, and the outer circumference of the rotating ring 71 is rotatably connected to a connecting sleeve 72. The cylindrical tube 63 can be rotated by the rotation effect of the rotating ring 71. A mounting ring 74 is inserted into the left inner wall of the connecting sleeve 72. By plugging the mounting ring 74 into the connecting sleeve 72, the delivery pipe 4 can be installed on the cylindrical tube 63. A sealing gasket 73 is fixedly connected to the inner wall of the connecting sleeve 72. By plugging the mounting ring 74 into the connecting sleeve 72, the mounting ring 74 and the connecting sleeve 72 squeeze the sealing gasket 73, so that the sealing gasket 73 expands and deforms, thereby sealing the gap between the mounting ring 74 and the connecting sleeve 72.

[0035] Reference Figure 2 and Figure 3The front inner wall of the fixed block 64 is elastically connected with a clamping block 65 through a spring 66. Through the elastic force of the spring 66, the clamping block 65 always maintains the clamping effect with the clamping groove 68 when not affected by external force, thereby limiting the fixed block 64. The outer wall of the fixed ring 67 is provided with a clamping groove 68, and the clamping groove 68 is provided with three groups. The clamping effect of different positions is achieved by the clamping block 65 and the three groups of clamping grooves 68, thereby achieving a limiting effect on different positions of the fixed ring 67.

[0036] Reference Figure 1 and Figure 3 The bottom of the diverter box 61 is fixedly connected to the top left end of the base 1. The fixing effect of the diverter box 61 prevents the diverter box 61 from falling off. The front of the diverter box 61 is fixedly connected to the left end of the connecting pipe 3. The three groups of connecting pipes 3 are respectively fixed to the front, back and bottom positions of the diverter box 61. A through hole is opened on the front of the rotating box 62. When the through hole corresponds to the connecting pipe 3, the refrigerant in the connecting pipe 3 can be transported to the rotating box 62 through the through hole. The outer periphery of the cylindrical tube 63 penetrates and is rotatably connected to the left inner wall of the diverter box 61. The rotating box 62 is driven to rotate by the rotation effect of the cylindrical tube 63.

[0037] Reference Figure 3 and Figure 4 The inner wall of the rotating ring 71 is fixedly connected to the left end of the cylindrical tube 63, and the front inner wall of the mounting ring 74 is elastically connected to a wedge block 75 through a limit spring 76. Through the elastic force of the limit spring 76, the wedge block 75 always maintains a clamping effect with the square groove 77 when not affected by external force, thereby limiting the mounting ring 74. A square groove 77 is provided on the front of the connecting sleeve 72.

[0038] Reference Figure 3 The outer periphery of the fixed block 64 is rotatably connected to the inner wall of the fixed ring 67, one end of the spring 66 is fixedly connected to the front inner wall of the fixed block 64, and the other end of the spring 66 is fixedly connected to the outer wall of the clamping block 65. The clamping block 65 is kept fixed by the fixing effect of the spring 66 to prevent the clamping block 65 from falling off.

[0039] Reference Figure 4 The locking cam 76 is in the form of a bolt, and the bolt has a cam face 72 thereon. The bolt has a cam face 73 which is adapted to move the bolts 72 together with the latch 72. The locking cam 76 is adapted to move the bolts 72 together with the latch 72 to allow the bolts 72 to move freely.

[0040] Reference Figure 3 The outer wall of the clamping block 65 is slidably connected to the front inner wall of the fixed block 64. Through the sliding effect of the clamping block 65, the clamping block 65 and the clamping groove 68 are clamped or released. The outer wall of the clamping block 65 is clamped to the inner wall of the clamping groove 68. Through the clamping of the clamping block 65 and the clamping groove 68, the fixing ring 67 limits the fixing block 64.

[0041] Working principle: When it is necessary to inject refrigerant into the air conditioner, the staff will install the delivery pipe 4 set on the refrigerant filling machine 5 on the cylindrical tube 63, and connect the mounting ring 74 set on the delivery pipe 4 with the connecting sleeve 72, so that the wedge block 75 is clamped with the square groove 77 under the elastic force of the limit spring 76, and the mounting ring 74 is limited. At the same time, the sealing gasket 73 is squeezed by the mounting ring 74 and the connecting sleeve 72, so that the sealing gasket 73 expands and deforms, and the gap between the mounting ring 74 and the connecting sleeve 72 is sealed, so that the delivery pipe 4 remains fixedly installed on the cylindrical tube 63.

[0042] The staff starts the refrigerant filling machine 5 to inject refrigerant into the air conditioner. When different types of refrigerants need to be filled into air conditioners of different models, the staff presses the card block 65 to release the card connection effect of the card block 65 with the card slot 68 and release the limiting effect on the fixed block 64. The cylindrical tube 63 is rotated to drive the rotating box 62 to rotate, and the through hole on the rotating box 62 is driven to rotate. When the through hole rotates to correspond to the connecting pipe 3 set on the refrigerant container 2 to be filled, The refrigerant required for filling stored in the refrigerant container 2 is transported to the rotating box 62 through the connecting pipe 3 and the through hole, and the refrigerant required for filling is transported to the cylindrical tube 63 through the rotating box 62 until it is transported to the refrigerant filling machine 5 for filling. At the same time, the output ports of the other two groups of connecting pipes 3 can be closed by the rotating box 62, thereby realizing the switching function. Through the elastic force of the spring 66, the block 65 is engaged with the slot 68, and the fixed block 64 is limited, so that the rotating box 62 remains fixed.

[0043] When the air conditioning refrigerant is injected, the staff presses the wedge block 75 to release the clamping effect of the wedge block 75 on the square groove 77 and release the limiting effect on the mounting ring 74, thereby facilitating the staff to disassemble the delivery pipe 4 and the cylindrical tube 63.
