A quick-release vacuum pump according to the present invention includes a vacuum pump part, a release part and a filter material. The pump part has a cylindrical hollow area extending between an inlet and an outlet and nozzles disposed in series inside the hollow area and have slots therein, both ends of the nozzles communicating with each other between the inlet and the outlet. The release part includes a support tube formed above a suction port, a skirt-type check valve to be moved up and down by air pressure to open and close the support tube, and a pressure chamber formed in a passage communicating with the suction port and passes by a valve skirt. And the filter material disposed between the suction port and the support tube allows discharge air to pass through upward when the pump part operates. |
