Abstract:
The present invention provides a device that can generate a pulsatile flow or intermittent flow from a continuously flowing of the water tap by pressure of the water tap without using an electrical activation part. The device for generating a pulsatile fluid or intermittent fluid comprises an injection mechanism 110 for injecting fluid, which is a liquid or gas; an air cavity 120 which includes an airtight space, a draining portion 150 disposed in the lower part; an air intake ventilation hole 141 connected to the ventilation pass 140. The injection point of the injection mechanism 110 is around the air intake ventilation hole 141, and the injected flow is formed so that a part of the injected flow runs downward for covering the surface of the side wall in which the air intake ventilation hole 141 is included. The air intake ventilation hole 141 is partially covered or brushed by the running flow, so the fluctuation rhythm of the air blow is generated, wherein the temporary air pressure decrease in the air cavity 120 given by the downward flowing of the injected flow and temporary air pressure recovery in the air cavity 120 given by the air blowing form the outer air are repeatedly. Therefore, the pulsatile flow or the intermittent flow is generated.
