ULTRASONIC SPRAY SYSTEM

摘要

An ultrasonic spray system includes an atomizer and a reservoir for supplying liquid to the atomizer for atomization. The atomizer includes a seat body, an ultrasonic vibration plate and a baffle plate. The seat body defines a chamber in fluid communication with the reservoir, and an opening in communication with the chamber. The ultrasonic vibration plate is mounted in the opening of the seat body for transforming liquid in the chamber into fine droplets that exit the atomizer through the opening in the form of a fog. The baffle plate is mounted in the seat body between the ultrasonic vibration plate and the chamber of the seat body. Moreover, the baffle plate defines a central hole smaller in diameter than the opening of the seat body for mitigating water pressure on the ultrasonic vibration plate, and a slot radially extending from the central hole for air to escape from the chamber of the seat body.

1. An ultrasonic spray system comprising:
an atomizer including a seat body defining a chamber and an opening in communication with the chamber; an ultrasonic vibration plate disposed in between the chamber and the opening of the seat body for transforming liquid stored in the chamber into fine droplets that exit the atomizer through the opening in the form of a fog; and a baffle plate mounted in the seat body between the ultrasonic vibration plate and the chamber of the seat body, and having a central hole smaller in diameter than the opening of the seat body for mitigating water pressure on the ultrasonic vibration plate, and a slot radially extending from the central hole for air to escape from the chamber of the seat body; a main reservoir arranged in fluid communication with the chamber of the seat body of the atomizer for supplying liquid to the atomizer; and an auxiliary reservoir arranged in fluid communication with the main reservoir; wherein the main reservoir is formed with a near-vacuum above liquid therein such that while some of the liquid flows from the main reservoir to the chamber of the atomizer, make-up liquid is automatically added to the main reservoir from the auxiliary reservoir.
