[0002] In the existing refrigerant charging method, it is mainly composed of refrigerant charging joints and connecting pipes. This refrigerant charging method has the following problems: First, in the process of use, some may be in contact with the refrigerant charging needle valve or some When the refrigerant filling interface is connected to the filling pipe joint, or when the filling pipe joint is removed after filling, due to unskilled or misoperation, liquid or a large amount of gaseous refrigerant will flow out, and hands are prone to frostbite. Second, every time the refrigerant is charged, it is necessary to connect the refrigerant charging pipe joint, and it often needs to be tightened manually and slowly, so the work efficiency is low; Separation causes a certain amount of leakage of refrigerant, resulting in waste
