<p>PURPOSE:To provide an inexpensive air pressure-in device for spraying air having simple structure and capable of easily supplying compressed air having suitable pressure in an air-spraying vessel. CONSTITUTION:An air spray main body 16 is set, while engaging a spray cap 15 with a cap holder 10, in a case main body 9 to be tightened with a hand screw 17. Turning a main switch 19 ON a motor and a rotary plate 3 in rotated in an arrow A direction. This rotation is converted into the vertical motion of a shaft 6 in an arrow B direction with a linking plate 8. This follows also the vertical motion of the cap holder 10 fixed to a nut at the shaft 6 lower end. The vertical motion of the spray cap 15 in an arrow C direction causes air to be supplied to the air spray main body 16, gradually raising inner pressure.</p> |
