Description

Technical Field

[0001] This utility model belongs to the field of refrigerant dispensing technology and relates to a refrigerant dispensing machine. Background Technology

[0002] After a period of use, impurities, water vapor, and incompressible gases can mix into the refrigerant in an air conditioner, causing a decrease in cooling efficiency. A refrigerant recovery and charging machine is a device that recovers, purifies, stores, and recharges the refrigerant from the air conditioning system. This saves refrigerant raw materials and prevents refrigerant from being released into the atmosphere and polluting the environment. The condenser is a crucial component of the charging machine, typically located between the recovery pipe and the refrigerant tank, or combined with the evaporator inside the casing. Condensate is collected in a water tank and sprayed onto the evaporator to improve heat exchange efficiency. Therefore, refrigerant charging machines generally generate heat during operation, which is typically dissipated through a combination of a cooling fan and heat dissipation channels. However, in actual use, dust and other impurities inevitably enter the heat dissipation channels, adhering to internal components. Excessive adhesion can affect the operation of the charging machine. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a refrigerant filling machine that facilitates heat dissipation and reduces the adhesion of impurities.

[0004] The objective of this utility model can be achieved through the following technical solution: A refrigerant charging machine includes a charging body, characterized in that a heat dissipation and dust prevention component is provided on the outer peripheral wall of the charging body at the condenser, which is connected to the condenser and used to improve heat dissipation and reduce the entry of impurities. The heat dissipation and dust prevention component includes a heat dissipation unit for air exchange and a switch unit for controlling the opening and closing of the heat dissipation unit. The heat dissipation unit includes an outer heat dissipation shroud and an inner heat dissipation shroud, which are respectively disposed on and connected to the two end faces of the outer peripheral wall of the charging machine. A through hole is provided on the outer peripheral wall of the charging machine at the outer heat dissipation shroud to connect the hollow cavity of the outer heat dissipation shroud with the hollow cavity of the inner heat dissipation shroud. The outer peripheral wall has several ventilation slots spaced apart along its circumference. The switch unit includes a hollow assembly shell and an opening / closing sleeve, a control switch, two mounting bases, and a connecting shaft. The assembly shell is located at and connected to a through hole in the outer peripheral wall of the dispensing machine. A folded edge ring is provided at the outer end of the assembly shell and is connected to and abuts against the outer peripheral wall of the dispensing machine. The opening / closing sleeve is located inside the assembly shell and is slidably fitted therewith. The two mounting bases are located on and connected to an inner heat sink. The control switch is connected to the two mounting bases through the connecting shaft. A movable groove is provided on the end face of the inner heat sink for the control switch to extend and move around the connecting shaft. The control switch and the opening / closing sleeve are connected through a connecting unit.

[0005] In the aforementioned refrigerant charging machine, the inner end face of the outer heat dissipation shroud is provided with an axially outward protrusion that cooperates with the opening and closing sleeve to form a sealing protrusion.

[0006] In the aforementioned refrigerant charging machine, the connecting unit consists of an assembly frame and a connecting strip. The assembly frame is located inside and connected to the opening and closing sleeve, and both ends of the connecting strip are connected to the assembly frame and the control switch respectively via connecting shafts.
