Sterilizing and insecticidal sprayer

A sterilizing and insecticidal sprayer comprising:

• an outer housing;
• a sterilized water container in which sterilized water is stored;
• an insecticidal liquid container in which an insecticidal liquid is stored;
• a three-way valve switched such that compressed air is selectively used to spray the sterilized water from the sterilized water container or to be supplied to the insecticidal liquid container;
• a vibration generator positioned in the insecticidal liquid container so as to generate vibration by the compressed air supplied from a compressor and a piezoelectric element;
• the piezoelectric element positioned at an upper portion of the vibration generator;
• an inner tube vertically extending through an axial center of the vibration generator so as to transfer the compressed air;
• a horn body positioned under the piezoelectric element so as to accommodate the inner tube;
• a horn body groove formed at a predetermined position of the inner tube;
• horn body holes formed through the horn body from the horn body groove;
• a circulating flow chamber formed in a space between the horn body and an exterior portion of the vibration generator;
• a plurality of blade vibration plates fixed to one side of a plurality of side surfaces formed in an exterior hole of the vibration generator so as to cover the plurality of side surfaces, in which the compressed air, which has passed through the horn body hole of the horn body from the inner tube, is circulated along the circulating flow chamber;
• and
• a plurality of bottom vibration plates covering a plurality of fan-shaped bottom surfaces formed in a bottom hole of the vibration generator, wherein the compressed air of the circulating flow chamber passes through the exterior hole and collides with the plurality of blade vibration plates and the bottom vibration plates,
• wherein the sterilized water container, the insecticidal liquid container and the three-way valve are positioned in the outer housing.
