Variable Frequency Portable Ultrasonic Cleaner

Abstract

The invention discloses a frequency-convertible portable ultrasonic cleaning device. The frequency-convertible portable ultrasonic cleaning device comprises a vibration body (1), a first piezoelectric ceramic plate (2) and a second piezoelectric ceramic plate (4), and is characterized that the vibration body (1), the first piezoelectric ceramic plate (2), a positive electrode (3), the second piezoelectric ceramic plate (4), a negative electrode (5) and a base (6) are connected into an integral structure through a pre-tightening screw (10); high-frequency signals of different frequencies can be generated by a circuit board (8) and are applied to the positive electrode (3) and the negative electrode (5), so that the first piezoelectric ceramic plate (2) and a second piezoelectric ceramic plate (4) are driven to generate telescopic effect simultaneously; the vibration body (1) soaked in cleaning liquid is activated to generate resonance, so that the vibration body (1) works at corresponding deformation modes and release different ultrasonic waves outwards; the ultrasonic waves activate the nearby liquid to generate cavitation; and broken micro bubbles after cavitation generate enough energy to wash off dirt on the surface of a target object soaked in the liquid. The frequency-convertible portable ultrasonic cleaning device is small in size and convenient to carry, and a market vacancy is filled up.

Description

technical field [0001] The invention relates to a cleaning technology, in particular to an ultrasonic cleaning technology, in particular to a frequency-variable portable ultrasonic cleaner which generates ultrasonic waves by high-frequency deformation of piezoelectric ceramics. Background technique [0002] Ultrasonic cleaning has advantages that other traditional cleaning methods cannot match—good cleaning effect, high consistency, high efficiency, low cost, low labor intensity and environmental friendliness. Traditional fruit and vegetable cleaning machines generally adopt spray, brush, drum and other structural forms. Among them, the spray cleaning machine consumes a lot of water, and there is a cleaning blind area for complex-shaped cleaning objects, and the decontamination effect is not good; the brush and The drum type washing machine is only suitable for cleaning root fruits and vegetables, and it will cause great damage to leafy vegetables and fresh fruits. The abov...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing ultrasonic cleaning equipment has a large volume, and the ultrasonic wave needs to pass through the cleaning box to enter the cleaning liquid, so the ultrasonic loss is large, the ultrasonic frequency is fixed, and different modes cannot be used for targeted cleaning according to the cleaning object. To solve the problem, design a variable-frequency portable ultrasonic cleaner that is small in size, easy to carry, and can be directly put into various cleaning containers to clean different cleaning objects using different cleaning modes.
