[0002] Currently, vehicle tires or various inflators (such as air beds, air boats, etc.) mainly need air compressors (or inflators) as the main inflation equipment to effectively save manpower and time. In addition, vehicle tires must be inflated by air compressors to accurately control the tire pressure and avoid insufficient tire pressure to improve driving safety.
[0003] The working principle of the air compressor is mainly driven by the internal motor to drive the crankshaft to rotate, which in turn drives the connecting rod to make the piston move up and down to change the volume of the cylinder, compress and discharge the gas with pressure, and finally inflate the object.
[0004] For the existing air compressor, if a pressure gauge is needed, a gas hole must be added to the cylinder of the air compressor, and an additional plastic pipe is configured. One end of the plastic pipe is connected to the gas hole of the cylinder, and the other end is connected to the pressure gauge inlet hole end connection. Then, fixed sleeves are arranged at both ends of the plastic pipe to fix the cylinder and the pressure gauge inlet hole end connection, so that the pressure gauge is installed.
[0005] However, the additional plastic pipe not only increases the overall cost of the air compressor, but also has problems such as aging and damage. In particular, the plastic pipe must be additionally installed with fixed sleeves at both ends connected to the cylinder and the pressure gauge inlet hole end connection, which makes the air compressor assembly process complex and difficult to process. Therefore, after analysis, these assembly costs and assembly time, as well as the aging and damage problems later, do not meet the consumer's durable use and the manufacturer's production cost, directly affecting the market competitiveness.
