[0033] A micro motor 23 is fixedly mounted on the mounting plate 18, a transmission end of the micro motor 23 is fixedly connected to one end of a side screw 24, and the other end of the side screw 24 is fixedly connected to a circular plate 26. The circular plate 26 is a circular plate-shaped structure, and the circular plate 26 is fixedly connected to the side screw 24. The circular plate 26 is used as a limiter, and the micro motor 23 fixedly mounted on the mounting plate 18 is started, so that the side screw 24 rotates along the threaded hole opened on the slider 25;

[0034] One end of the upper screw rod 20 is rotatably connected with the first limit block 21, and the other end of the upper screw rod 20 is fixedly connected with the transmission shaft of the driving motor 29. The driving motor 29 is fixedly mounted on the connecting plate 28. The connecting plate 28 is an "L"-shaped plate structure. The bottom surface of the connecting plate 28 is fixedly connected with a second limit block 30. The second limit block 30 is a square plate structure. The first limit block 21 is a square plate structure. The first limit block 21 is stuck in the limit groove 22 opened on the bottom plate 8. The limit groove 22 is a square groove structure. The bottom plate 8 has limit grooves 22 at both ends, and the second limit block 30 fixedly connected to the connecting plate 28 is also stuck in the limit groove 22 opened on the bottom plate 8. The first limit block 21 and the second limit block 30 can slide along the limit groove 22. The first limit block 21 and the second limit block 30 have the same function and perform a limiting function, so that the mounting plate 18 and the first limit block 21 slide toward each other along the limit groove 22 opened on the bottom plate 8.

[0035] The bottom plate 8 is in the shape of a square plate structure. The connecting block 9, which is also in the shape of a square plate and is fixedly connected to the bottom of the bottom plate 8, is fixedly installed inside the main body 1 of the refrigeration unit. The main limiting plate 14 and the secondary limiting plate 15 are fixedly connected to the bottom plate 8. The secondary limiting plate 15 is in the shape of a square plate structure, and the main limiting plate 14 is in the shape of a "U"-shaped plate structure.

The conveying hose 7 is limited by the combined body, which facilitates the rolling of the conveying hose 7 by the roller 17. Moreover, there is a gap between the side surfaces of the main limiting plate 14 and the secondary limiting plate 15, which allows the rotation shaft on the mounting plate 18 to move. When the roller 17 squeezes the conveying hose 7, the side surface and the end surface of the roller 17 just come into contact with the inner side surface of the main limiting plate 14 to limit the roller 17. By moving the mounting plate 18, the roller 17 rotatably connected to the mounting plate 18 through the rotation shaft moves downward along the square groove 16 provided on the main limiting plate 14 to squeeze the conveying hose 7;

[0036] The side screw 24 is threadedly connected to the threaded hole provided on the slider 25. The slider 25 is in the shape of an "I"-shaped plate structure. The slider 25 is stuck in the chute 27 provided on the bottom plate 8 and can slide along the chute 27. The chute 27 is in the shape of a square groove structure. When the driving motor 29 is started to drive the upper screw 20 to rotate, the upper screw 20 rotates along the threaded hole provided on the fixing plate 19, and then the mounting plate 18 and the slider 25 can be driven to slide along the chute 27 provided on the bottom plate 8;

[0037] The upper screw 20 is threadedly connected to the threaded hole provided on the fixing plate 19. The fixing plate 19 is in the shape of a square plate structure. The side surface of the fixing plate 19 is fixedly connected to the side surface of the mounting plate 18. The mounting plate 18 is in the shape of an "L"-shaped pressing structure. The mounting plate 18 is rotatably connected to the roller 17 through the rotation shaft, so that the roller 17 can be driven to move inside the main limiting plate 14 and roll the conveying hose 7. Then continue to move, and through the above structure, the roller 17 moves upward along the square groove 16 provided at the other end of the main limiting plate 14 to disengage from the conveying hose 7 and no longer squeeze the conveying hose 7. On the one hand, by rolling the conveying hose 7 with the roller 17, the flow rate of the refrigerant inside the conveying hose 7 can be accelerated. On the other hand, by rolling the conveying hose 7 with the roller 17, the residual refrigerant inside the conveying hose 7 can continue to flow into the rigid conveying pipe 10. The residual refrigerant is pushed to continue flowing by the sealing plug 32, and flows into the refrigerant storage tank through the refrigerant conveying joint 11 and the recovery clamp, realizing the recovery of the refrigerant. Through the above, the recovery utilization rate of the refrigerant is improved, the waste of the refrigerant is reduced, the use effect of the device is improved, and it is convenient for personnel to actually use.

[0038] Embodiment III

[0039] On the basis of the second embodiment, in order to improve the use effect of the device, an electric push rod 12 is provided, the electric push rod 12 is fixedly installed on the hard conveying pipe 10, and a support block 13 is fixedly connected to the side of the hard conveying pipe 10, and the other end of the support block 13 is fixedly installed in the refrigeration unit body 1, and the door panel 2 and the condenser body 3 are installed on the refrigeration unit body 1. The other end of the support block 13 is fixedly installed in the refrigeration unit body 1 to support the hard conveying pipe 10. By starting the electric push rod 12, the push plate 31 is pushed to move, and the sealing plug 32 is a cylindrical structure. The diameter of the sealing plug 32 is equal to the inner diameter of the hard conveying pipe 10 and the diameter of the push plate 31. The push plate 31 is a circular plate-shaped structure, and the sealing plug 32 is pushed by the push plate 31 to move along the hard conveying pipe 10;

[0040] The push plate 31 is a circular plate-like structure, which is fixedly connected to the telescopic end of the electric push rod 12. The electric push rod 12 is fixedly installed on the hard conveying pipe 10. A refrigerant conveying joint 11 is installed at the other end of the hard conveying pipe 10. On the one hand, the sealing plug 32 can push the remaining refrigerant in the hard conveying pipe 10 to move to the refrigerant conveying joint 11 and flow into the refrigerant storage tank through it. On the other hand, the sealing plug 32 can block the connection between the conveying hose 7 and the hard conveying pipe 10. Even if there is any residual refrigerant in the conveying hose 7, when the refrigerant recovery clamp is detached from the refrigerant conveying joint 11, the residual refrigerant in the conveying hose 7 will not be sprayed out, which is convenient for personnel to use.

[0041] Working principle: In actual use, by driving the upper screw 20 to rotate along the threaded hole opened on the fixing plate 19, the mounting plate 18 and the roller 17 are moved along the slide groove 27, and the roller 17 is squeezed. On the one hand, the roller 17 rolls the delivery hose 7 to accelerate the flow speed of the refrigerant in the delivery hose 7 and improve the efficiency. On the other hand, the roller 17 rolls the delivery hose 7 to make the residual refrigerant in the delivery hose 7 continue to flow into the hard delivery pipe 10, and the residual refrigerant is pushed to continue to flow through the sealing plug 32, and the refrigerant is delivered to the refrigerant delivery interface. The refrigerant in the rigid delivery pipe 10 is pushed to move to the refrigerant delivery joint 11 through the sealing plug 32 and flows into the refrigerant storage tank through it. On the other hand, the sealing plug 32 can block the connection between the delivery hose 7 and the rigid delivery pipe 10. Even if there is any refrigerant remaining in the delivery hose 7, when the refrigerant recovery pliers are detached from the refrigerant delivery joint 11, the refrigerant remaining in the delivery hose 7 will not spray out and splash onto the body of personnel, which is convenient for personnel to use.
