Title:
ULTRASONIC TYPE SPRAY DEVICE
Document Type and Number:
Japanese Patent JPH02189161
Kind Code:
A
Abstract:

PURPOSE: To enable the feed of water which exercises no influence on stability of contact between a water feed body and an atomizing means by a method wherein a contact position relation between the atomizing means and the water feed body is primarily fixed and a feed water tank is connectable and disconnectable to and from the water feed body and removably mounted on a body.

CONSTITUTION: A water feed body 14 is securely pressed in a vibration horn holding frame 9 from a position below an ultrasonic vibrator 10. A taper hole 20 is formed in the end part of the water feed body 14, and the taper hole 20 and a tapered chamfered part 19 of a metallic horn 16 are secured in a position relation in which the metallic horn and the chamfered part make contact with each other. In the feed of water in the feed water tank 3, the feed water tank 3 is pulled off downwardly, and after water is supplied, an engaging port part 3a is pressed, in a similar manner described above, in an engaging cylinder part 9a of a vibration horn holding frame 9 for engagement to set the feed water tank against. Since a guide groove having an uneven surface is formed in housings 4 and 4' and the feed water tank 3 so that the feed water tank 3 is prevented from making contact with the water feed body 14, the feed water tank can be reliably mounted and demounted downwardly. This constitution enables stabilization of a contact condition between the water feed body and the ultrasonic vibrator of the atomizing means and realization of stable spray.
