Embodiment Construction

[0020] Such as figure 1 As shown, a piezoelectric liquid spray device 10 is resting on an adjacent surface 12, which may be a tabletop; the device sprays a cloud 14 of small liquid droplets into the air in the form of a fine mist to a certain height, For example, about 5 to 20 centimeters above surface 12 . The small droplets then fall back towards the top of the spray device and the surface 12 itself. As the droplets fall, they evaporate so that virtually no or only a small amount of liquid in the emitted droplets contacts the top or surface 12 of the spray device 10 .

[0021] The spray device 10 comprises a housing 16 in which a container 18 is mounted. Container 18 contains a liquid solution 20 to be launched into the air. Spray assembly 22 is housed in housing 16 , just above container 18 . Spray assembly 22 includes an annular piezoelectric actuator 24 and a circular orifice 26 . The orifice plate can extend through the central hole of the actuator device 24 and be ...

Abstract

An atomizer (10) atomizes a multi-component liquid from a reservoir (20) into a cloud (14) comprising small droplets which are ejected into the atmosphere to a certain height and allowed to fall toward surface (12). Essentially complete evaporation is assured by maintaining the size of the droplets, the liquid's component vapor pressures and the height through which the droplets fall according toa predetermined relationship. Also, the suitability of a liquid for evaporation in a vibrating plate atomizer is determined by measuring the rate of size decrease and the surface tension of a pendantdrop of the liquid after a predetermined amount of the liquid has evaporated from the drop.

Description

technical field [0001] The present invention relates to the diffusion of multi-component liquids such as insecticides and aromatic solutions by spraying a cloud or mist of small droplets of said liquid into the air by means of a vibrating spray plate This is achieved by the evaporation of liquid components from the droplet as it falls. Background technique [0002] It is well known to diffuse fragrances and insecticides into the air by vibrating a spray plate to form a mist or cloud containing small droplets of a solution of fragrance or insecticide and to spray said mist or cloud into the air. As the mist or cloud sinks, the fragrance or insecticide evaporates from the droplets. Examples of devices that do this are disclosed in US Patent Nos. 4,085,893, 5,173,274, 5,601,253 and 5,894,001. Typically these devices supply a liquid fragrance or insecticide to a vibrating spray plate which, due to the vibration of the vibrating spray plate, breaks up the liquid into fine drop...
