Air pump for decoration

The utility model discloses an air pump for decoration, which comprises an air storage tank (1), a compressor (2), a pressure gage (6), a pressure switch (5) and an oil-water separator (4), wherein the air storage tank (1) and the compressor (2) are communicated through a pipeline; simultaneously, the air storage tank (1) is communicated with the pressure gage (6), the pressure switch (5), the oil-water separator (4) and an air outlet pipe (3) through the pipeline; the pressure switch (5) and the compressor (2) are electrically connected; and a refrigeration compressor is adopted as the compressor (2). After the structure is adopted, due to the fact that the market compressor which is special for refrigerators is adopted as the compressor of the air pump, the noise generated when the air pump for the decoration works is very small by utilizing the working characteristics of high efficiency and small noise of the refrigerator compressor, and thereby, the living of surrounding residents is not influenced.
