Description

TECHNICAL FIELD Embodiments of the invention relate to a compact pressurized air supply system that includes mechanisms for noise suppression and heat dissipation. BACKGROUND OF THE INVENTION Conventional compact pressurized air supply systems, such as a tabletop or a portable air pump, typically have many drawbacks. For example, conventional compact air pumps often do not have an effective mechanism for blocking the noise generated during operation. The noise generated by the air pump can be unpleasant and annoying to users and people in the immediate vicinity. Furthermore, heat generated during the operation of a conventional compact air pump is often poorly controlled. The air pump may need to be shut down after it is used continuously for a long time. The shutdown disrupts the continuity of the work process. A conventional compact air pump also has the problem of imprecise and inconsistent control of the air pressure that it outputs. For example, some conventional compact air pumps control the air pressure by stopping the air pump operation when the air pressure reaches a target, and restarting the air pump operation when the air pressure is insufficient. Frequent starting and restarting of the air pump cause instantaneous high current, which can affect the lifespan of the air pump parts. Therefore, there is a need for improving the design and operation of conventional compact air pumps. SUMMARY OF THE INVENTION In one embodiment, an air supply system is provided for supplying compressed air. The air supply system includes an air pump assembly to generate the compressed air. The air pump assembly includes an outer sealed box enclosing an inner sealed box, and the inner sealed box further encloses air pump machinery. A first set of springs are disposed between the air pump machinery and the inner sealed box and a second set of springs are disposed between the outer sealed box and the inner sealed box. The air supply system further includes a liquid circulation pipe to circulate a cooling liquid. The liquid circulation pipe connects the air pump machinery to liquid cooling components outside the outer sealed box. The air supply system further includes a sensor coupled to an output of the air pump assembly to measure a characteristic of the compressed air during operation of the air pump machinery, and a programmable control board to control a speed of a motor in the air pump machinery according to program instructions and measurements of the sensor. In another embodiment, an air supply system includes an air pump assembly, a liquid circulation pipe, a sensor, a programmable control board, and an air output valve. The air pump assembly includes air pump machinery to generate compressed air. The air pump assembly includes an outer sealed box enclosing an inner sealed box, and the inner sealed box further encloses the air pump machinery. A first set of springs are disposed between the air pump machinery and the inner sealed box and a second set of springs are disposed between the outer sealed box and the inner sealed box. The liquid circulation pipe circulates a cooling liquid. The liquid circulation pipe connects the air pump machinery to liquid cooling components outside the outer sealed box. The sensor is coupled to an output of the air pump assembly to measure a characteristic of the compressed air during operation of the air pump machinery. The programmable control board controls the speed of a motor in the air pump machinery according to program instructions and measurements of the sensor.
