Background
The control components on the traditional air compressor are mainly a pressure switch and a pressure gauge, the pressure switch can be automatically controlled through air pressure, and manual control can also be carried out through a manual button. When the air pressure in the air storage tank rises to the preset shutdown pressure of the pressure switch, the switch is automatically switched off, and the air compressor is automatically stopped (for example, 8bar shutdown); when the air pressure in the air storage tank is reduced to the preset starting pressure, the pressure switch is automatically switched on, and the air compressor is automatically started (such as 6bar starting). This keeps the air pressure output by the air compressor within normal use. The pressure setting is adjusted by pre-tightening a spring by an adjusting screw rod in the pressure switch, but the adjusting mode has insufficient precision and causes the stop and start pressure to deviate from a set value due to the deformation of the spring.
In addition, the pressure of the conventional air compressor is displayed by a pressure gauge. The pressure gauge has two, and one shows the pressure in the gas holder, and the pressure of gas vent is shown to another one. The traditional pressure gauge is of a needle type, a dial plate is provided with two units of a metric system (bar) and an English system (psi), and although the unit system can be distinguished through the color of scales, the traditional pressure gauge is not intuitive after all. Simultaneously, the pointer shake often makes the registration accuracy difficult for reading when using because of user's visual angle deviation and air compressor, and the registration of manometer also is difficult to see clearly under the not good environment of light. In addition, conventional air compressor control systems are too mechanized to be suitable for small air compressors for home use.
