Problems solved by technology

[0002] The existing quick connectors for air conditioners solve the problems of quick connection between the indoor unit and the outdoor unit and the complex assembly process of the air conditioner during installation. For example, the patent No. ZL200420109858.3 discloses a quick connector for air conditioners. The quick connector is better It solves the problems of complex installation operation, poor connection stability, inconvenient disassembly, maintenance and disassembly, and easy leakage of freon in the copper pipe during the installation of the air conditioner.

Another example is that the patent No. ZL200520115846.6 discloses a one-piece quick connector for an air conditioner. This quick connector solves the problem of complex assembly process, can reduce the cost of assembly, facilitates the assembly factory, and improves the quality of the whole machine.

However, the above-mentioned quick connector is usually connected with the air-conditioning shut-off valve by welding, the plug body is integrated, the axial positioning of the fixed ejector rod is not reliable, the design of the sealing structure is not reasonable, the connection operation is complicated, the connection reliability is low, and it is difficult to Insufficient maintenance, poor sealing connection stability, etc.
