Problems solved by technology

[0009] However, such atomizers and / or dispensers do not provide a system in which the dispensed liquid is sprayed onto the oscillating mechanism / surface without causing attenuation of the piezoelectric oscillation frequency
Furthermore, the prior art fails to provide a battery-operated portable dispenser capable of long-term use with constant or little variation in the dispense rate using an orifice plate mechanically coupled to a piezo element

Embodiment Construction

[0023] Embodiment of the invention

[0024] It is to be understood that the drawings and the following description are directed to preferred embodiments of the invention, but that the invention itself is broader than the examples shown. Rather, the invention is equally applicable to other piezoelectric atomization forms, such as atomizers that use cantilever beams and / or stiffeners and are driven by a conventional power source, such as a wall plug, rather than batteries.

[0025] figure 1 The overall relationship between the printed circuit boards 1 where the piezoelectric elements 2 are placed is drawn. For the sake of clarity and ease of understanding of the present invention, the circuit board 1 is shown without circuits and batteries connected thereto. It will also be appreciated that the circuit board may in use be connected to the base of the dispenser which in turn is located in a decorative shell-type housing or in a socket (not shown) for use. exist Figure 5 In ,...

Abstract

Disclosed herein is a piezoelectric liquid delivery system or atomizer for production of droplets of liquid or liquid suspensions by means of a battery operated continuous action dispenser utilizing an orifice plate (3) in communication with a piezoelectric element (2). By use of a wick (7) having specified properties and high compliance, superior results are achieved.

Description

technical field [0001] The present invention relates to devices for dispensing active liquids such as perfumes, air fresheners, insecticide compositions or other materials in the form of fine particles or droplets, such as in the form of a fine spray, through piezoelectric devices. In particular, the object of the present invention is a piezo-electric liquid delivery system that generates droplets or suspensions by means of electromechanical or electroacoustic actuation. More specifically, the present invention relates to battery operated dispensers utilizing an orifice plate connected to a piezoelectric element. An improved method of dispensing such liquids is obtained by appropriate choice of means for diverting liquids from the liquid container to the orifice plate. Background technique [0002] Dispensing of liquids by forming a fine spray or atomization is well known. One such dispensing method is to atomize the liquid by sound vibrations produced by ultrasonic piezoe...
