Description
Technical field
It the utility model is related to a kind of auto repair care device, and in particular to a kind of car air conditioner refrigerant addition dress
Put.
Background technology
Automotive air-conditioning system is an important part for the comfort level of driver, especially the summer in sweltering heat.
But with the long time running of air-conditioning system, the content of its refrigerant can decline, and cause the refrigeration of air-conditioning to decline.Usual people
Need automobile specifically to maintain shop to add refrigerant, but the way wastes time and energy.Therefore, accordingly generate 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 is following problem in 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 produced if misoperation.Secondly as traditional refrigerant addition instrument is by a root thorn pin
The strip of paper used for sealing of gas tank dress refrigerant cover is punctured, allows refrigerant to be flowed out from gas tank, and then is flowed into automotive air-conditioning system, but
The strip of paper used for sealing of gas tank mouth is usually required that using the iron or other metal systems for having some strength, rigidity and hardness due to the needs of sealing
Into therefore, the requirement to pricker is higher.Finally, the strip of paper used for sealing of traditional gas tank dress refrigerant cover is after use is punctured,
It will be unable to effectively seal, therefore, remaining refrigerant can be leaked in air in tank, so as to cause the waste of refrigerant and sky
Gas pollutes.
