<p>The present invention relates to a noiseless pressure blower including a main body having a hollow portion, an inlet port for sucking in a fluid, and an outlet port for discharging the fluid sucked in; a pressing member mounted in the hollow portion of the main body, and which rotates to suck in the fluid from the inlet port; a control member mounted in the hollow portion of the main body, and which rotates in contact with the pressure member to prevent the sucked in fluid from flowing to the inlet port; and a connection means for connecting the rotating force generated by a motor to the pressure member and the control member. The main body has a shape in which two cylinders communicate with each other via the side surfaces thereof. The pressure member includes a pressure rotating shaft which rotates by the connection means, and a spiral pressure plate mounted on the pressure rotating shaft. The control member includes a control rotating shaft which rotates by the connection means, and a control body mounted on the control rotating shaft, and which rotates in linear contact with the pressure plate. The above-described configuration of the present invention prevents noise during high or low speed rotation, reliably conveys air even when resistance is caused by a duct by sucking in and discharging air through the pressure member and the control member, and reduces the consumption of electrical power.</p> |
