Description
Technical field
The present invention relates to a kind of auto repair care devices, and in particular to a kind of car air conditioner refrigerant adding set.
Background technique
Automotive air-conditioning system is important a part for the comfort level of driver, especially in the hot summer.
But with the long time running of air-conditioning system, the content of refrigerant can decline, and the refrigeration effect of air-conditioning is caused to decline.Usual people
Need automobile specifically to maintain shop to add refrigerant, but the way is time-consuming and laborious.Therefore, it accordingly produces portable
The refrigerant of the gas tank dress of formula, driver can do it yourself to add refrigerant directly to air-conditioning system.
However, there are the following problems for traditional addition manner: firstly, since the refrigerant of air conditioning for automobiles can destroy it is smelly
Oxygen layer and atmospheric environment, so filling tool and air conditioning for automobiles interface must be kept when filling refrigerant to air conditioning for automobiles
It is tightly connected, leakage can be generated if misoperation.Secondly as traditional refrigerant addition tool is by a root thorn needle
The strip of paper used for sealing of gas tank dress refrigerant cover is punctured, allows refrigerant to flow out from gas tank, and then be flowed into automotive air-conditioning system, but
The strip of paper used for sealing of gas tank mouth is usually required that due to the needs of sealing using the iron or other made of metal for having some strength, rigidity and hardness
At therefore, the requirement to pricker is relatively high.Finally, traditional gas tank fills the strip of paper used for sealing of refrigerant cover after being punctured use,
It will be unable to effectively seal, therefore, remaining refrigerant can be leaked in air in tank, to cause waste and the sky of refrigerant
Gas pollution.
