A diffuser that may receive a refill bottle that supplies fragrance to the diffuser is provided. The diffuser includes a seat to facilitate easy placement and alignment of the refill bottle in the diffuser. The diffuser has an arm that can rotate about a pivot axis. The arm may rotate away from the seat to allow the user to place the refill bottle into the seat of the diffuser. The arm may also rotate towards the seat such that the arm can be placed over the refill bottle. The arm contains a piezo-electric component that can atomize the fragrance supplied by the refill bottle. The arm also includes a plurality of springs to create sufficient contact between the piezo and the refill bottle, to apply a downward force on the refill bottle, and to engage with a lock to secure the arm over the refill bottle.

An aromatherapy diffuser includes a diffuser body and a diffusion device. The diffuser body has an oil storage cavity for storing a predetermined amount of essential oil. The diffusion device is supported in the diffuser body, and includes an ultrasonic vibrator arranged to generate ultrasonic vibrations, in such a manner that when the diffusion body is partially immersed in the water stored in the container, the essential oil is released to the water from the oil storage cavity while the ultrasonic vibrator is arranged to cause ultrasonic vibrations in the water so as to agitate the water molecules for releasing negatively charged mist and essential oil into ambient air.

Spraying apparatus enabling large-volume generation of particles minute to a Brownian-motion engendering level. The spraying apparatus includes an atomization tank, an atomizing device, a blower, an atomization unit furnished with a liquid-level sensor for measuring liquid level in the atomization tank, a tank unit for supplying liquid formulation to the atomization tank, and a control unit for controlling supply of the liquid formulation from the tank unit to the atomization tank. If the liquid level measured by the liquid-level sensor falls below a predetermined first level h.sub.1, the control unit starts supply of the liquid formulation from the tank unit to the atomization tank, and if the liquid level measured by the liquid-level sensor reaches a predetermined second level h.sub.2 higher than the first level h.sub.1, the control unit halts supply of the liquid formulation from the tank unit to the atomization tank.

Afforded is a spray apparatus that enables the large-volume generation of fine particles having particle diameters minute to a level that can give rise to Brownian motion. A spray apparatus of the present invention is furnished with: an atomization tank 11; an atomizing device 12; a blower 13 that blows air through a blow port 11b; and send-out port 11c; a first baffle plate 14a and a second baffle plate 14b, connected to an inner side of a top panel of the atomization tank. The first baffle plate 14a is furnished with a first edge piece 14ae disposed spaced apart at a predetermined spacing from an inner face of the atomization tank 11 along one widthwise end thereof, and the blow port 11b is arranged to the one widthwise end of a connection piece 14ac between the first baffle plate 14a and the atomization tank 11.
