PROBLEM TO BE SOLVED: To provide an effective component supply device which reduces costs by decreasing a passage switching valve. SOLUTION: An air gun 20 including a cylinder 21 and a piston 22 is installed. An emission port 23 is formed at one end of the cylinder 21, and a communication port 24 is formed at the other end of the cylinder 21. A perfume container 31 for generating a perfume component is installed, and the perfume container 31 communicates with an inlet 37 of the cylinder 21. An ozone generator 40 for generating ozone is installed, and the ozone generator 40 communicates with the communication port 24 of the cylinder 21. When air containing the perfume component is released from the emission port 23, the inlet 37 is communicated with the emission port 23 by moving the piston 22 to a retracted position, so that the front side of the piston 22 is filled with the perfume component. When deodorizing air containing a lingering scent of the perfume component, the inlet 37 is communicated with the communication port 24 by moving the piston 22 to the advanced position, so that the air is admitted through the communication port 24 to the ozone generator 40. Thus, the piston 22 functions as the passage switching valve. COPYRIGHT: (C)2011,JPO&INPIT |
