[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1 to 3 As shown, this embodiment includes a recycling machine housing 1, which has an enclosed shell structure with an opening on one side, providing a closed and orderly installation space for the internal components. Inside the recycling machine housing 1, a condenser 2, a refrigerant compressor 5, a drive motor 6, a cooling fan 7, and a radiator 8 are installed in sequence, with each component arranged in an orderly manner.

[0018] like Figures 1 to 3As shown, the refrigerant compressor 5 and the drive motor 6 are arranged in a horizontal coaxial structure to ensure the coaxiality and stability of power transmission. A connecting front cover 61 is fixedly installed on the front side of the drive motor 6. The other end of the connecting front cover 61 is fixedly connected to the side of the refrigerant compressor 5, forming a rigid connection between the refrigerant compressor 5 and the drive motor 6. The connecting front cover 61 is a hollow cylindrical structure and a coupling 9 is installed inside. The drive shaft 51 extending from the refrigerant compressor 5 and the motor shaft 62 extending from the drive motor 6 are respectively connected to both sides of the coupling 9, so that the power can be efficiently transmitted through the coupling 9.

[0019] like Figures 1 to 3 As shown, the stroke cylinder 4 is fixedly installed on the top of the refrigerant compressor 5 and connected to the inside of the refrigerant compressor 5. It is used to control the working stroke of the compressor. The dual-cylinder control valve 3 is connected to the top of the stroke cylinder 4 and is internally connected. The action of the stroke cylinder 4 is adjusted by the dual-cylinder control valve 3. The top mounting plate 10 is fixedly installed on the top of the recovery machine housing 1. The radiator 8 is fixedly connected to the lower end of the top mounting plate 10. The top mounting plate 10 is used to achieve a stable assembly of the radiator 8. The pressure gauge 11 is fixedly connected to the lower end of the top mounting plate 10 on one side of the radiator 8. The pressure gauge 11 is used to monitor the system pressure in real time. The top of one side of the dual-cylinder control valve 3 is fixedly connected to the top mounting plate 10 to further improve its installation stability. The cooling fan 7 is connected to the other end of the motor shaft 62 and is directly driven by the drive motor 6. The condenser 2 is installed inside the recovery machine housing 1 on the front side of the refrigerant compressor 5, forming a key link in the heat dissipation path.

[0020] To elaborate further, such as Figures 1 to 3 As shown, the open end of the recycling machine housing 1 is fixedly connected to the rear cover 12 and the rear mounting plate 13. An integral insert plate 14 is fixedly installed on the outside of the rear mounting plate 13. A lithium battery 16 is connected to the outside of the integral insert plate 14 to provide portable power for the device. A heat dissipation shroud 17 is fixedly connected to the inside of the rear mounting plate 13. The heat dissipation shroud 17 covers the outside of the cooling fan 7 and enhances the heat dissipation efficiency by guiding the airflow direction.

[0021] To elaborate further, such as Figure 2 As shown, a mounting platform 63 is formed on the upper end of the drive motor 6, and a support body 18 is fixedly connected to the lower end of the top mounting plate 10. The lower end of the support body 18 is fixedly connected to the mounting platform 63.

A compressor bracket 52 is fixedly installed at the lower front end of the refrigerant compressor 5, and a second rubber base 53 is installed at the lower end of the compressor bracket 52. The first rubber base 65 and the second rubber base 53 are both fixedly connected to the bottom of the inside of the recycling machine housing 1. While achieving fixed support, the vibration and noise of the equipment during operation are reduced by the shock absorption characteristics of the rubber material.

Both extend outside the housing 1 of the recovery machine for easy connection to external pipelines. A knob 21 is connected to the top of the dual-cylinder control valve 3.
