Abstract
The invention relates to an air pump air pressure automatic controller which comprises an air cylinder, a spring, a piston, a screw, a pushing rod, a lever, a normally open micro-switch, a normally closed micro-switch and an alternating current contactor. The lower end of the air cylinder is communicated with the bottom of an air tank. The piston and the spring are arranged in the air cylinder. Threads are arranged inside the upper end of the air cylinder and used for fixing the screw. The piston, the spring and the screw are sequentially stacked upwards. The lower end of the spring jacks the piston and the upper end of the spring jacks the screw. The pushing rod is fixed to the piston, penetrates through the spring and the screw and is connected with the left side of the lever. A pivot is arranged in the middle of the lever. The normally open micro-switch is installed above the right end of the lever and the normally close micro-switch is installed below the right end of the lever. When air pressure is low, the spring pushes the piston to move downwards, the right end of the lever presses the normally open micro-switch upwards, so that the normally open micro-switch is turned on, the alternating current contactor is powered on at this moment, and a motor is started to drive an air pump to supply air. When air pressure is high, the piston is pushed upwards through air pressure, the right end of the lever presses the normally closed micro-switch downwards, so that the normally closed micro-switch is turned off, and the motor stops supplying air.
