1. A spraying apparatus comprising:
an atomization tank having a predetermined width, enabled for storing a liquid formulation;
an atomizing device being ultrasound vibrating elements plurally arranged widthwise in the atomization tank interior, for atomizing the liquid formulation to generate fine particles;
a blower furnished with a blowing element enabled for maintaining predetermined rpm, for blasting into the atomization tank interior, through a blow port provided in the atomization tank, conveyance air that is for conveying the fine particles of the liquid formulation;
a send-out port, provided in the atomization tank, through which the fine particles are sent out together with the conveyance air;
a first baffle plate arranged so as to receive liquid columns of the liquid formulation, produced by an ultrasound vibration element that among said ultrasound vibration elements is arranged along one widthwise end thereof;
a second baffle plate arranged so as to receive liquid columns of the liquid formulation, produced by an ultrasound vibration element that among said ultrasound vibration elements is arranged along the other widthwise end thereof; wherein
the first baffle plate is arranged inclined laterally or diagonally downward, directed toward the one widthwise end of the atomization tank, and is furnished with a first edge part disposed in the atomization tank spaced apart at a predetermined spacing from an inner face along the one widthwise end, and with a first connection part, connected to an inner side of a top panel of the atomization tank;
the blow port is arranged along the top panel of the atomization tank more to the one widthwise end of the atomization tank than is the first connection part, and more to the other widthwise end of the atomization tank than is the first edge part;
the second baffle plate is arranged inclined laterally or diagonally downward, directed toward the other widthwise end of the atomization tank, and is furnished with a second edge part disposed in the atomization tank spaced apart at a predetermined spacing from an inner face along the other widthwise end, and with a second connection part, connected to the inner side of the top panel of the atomization tank; and
the send-out port is arranged more toward the other widthwise end of the atomization tank than is the second connection part.
