<P>PROBLEM TO BE SOLVED: To provide a nozzle which can improve cleaning effect by outflowing air bubble-mixed water. <P>SOLUTION: The nozzle 1A includes: an inflow part 11 which is connected to a water outlet port and in which water from the water outlet port flows; a throttle part 12 which throttles a flow of the water flowed from the inflow part 11 and increases a flow rate of the water; an air introducing part 13 by which air is sucked into the water flowing out from the throttle part 12 to a downstream side to mix air bubbles, and air is introduced to make the air bubble-mixed water; and an intermittent shut-off means 14 which intermittently shuts off inflow of the water to the throttle part 12. By intermittently shutting off the inflow of the water to the throttle part 12 by the intermittent shut-off means 14, a flow rate of the outflowing air bubble-mixed water is intermittently changed, and a pulsative flow of the air bubble-mixed water is achieved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
