Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of refrigerant accessories, and relates to a refrigerant bottle opener. BACKGROUND

[0002] At present, the refrigerant filling of refrigeration equipment such as air conditioners and refrigerators is generally carried out by connecting the refrigerant tank with the equipment to be filled and using the pressure difference between the two to fill, and the refrigerant used in the automobile air conditioner is usually stored in the refrigerant tank, and the automobile repair shop uses a special refrigerant bottle opener to open the refrigerant tank, and the refrigerant is discharged through the connecting pipe, which is convenient for the transportation of the refrigerant. However, in reality, the pressure of the equipment to be filled is often greater than the pressure in the refrigerant tank due to various reasons, which causes the pressure in the refrigerant tank to increase sharply and causes the refrigerant tank to explode and other technical accidents, resulting in economic losses. At the same time, when the discharge pipe is not connected to the bottle opener, impurities may enter from the bottle opener joint, which will also add impurities during filling, affecting subsequent use, and the impurities entering the bottle opener also cannot be cleaned, thus not meeting the use requirements.
