Abstract
The utility model relates to an ultrasonic cleaner comprising an ultrasonic cleaner body and an ultrasonic generating circuit board provided in the ultrasonic cleaner body which is characterized in that a rectifier circuit, a filter circuit, an inverter circuit generating a high frequency oscillation signal from a direct current voltage, a resonant circuit and a transformer coupling the high frequency oscillation signal to the resonant circuit. The resonant circuit comprises a feedback transformer, a transducer, and an adjustable inductor. The ultrasonic generating circuit board can generate at least two frequencies for parts to be cleaned getting many types of cleaning through a converting of the frequencies. Such as rough cleaning, fine cleaning and so on. Twice wave crest powers are generated in a cleaning tank helping to removing a bigotry dirt thus cleaning a possible and different dirt on the parts to be cleaned completely.
Description
(1) technical field
The utility model relates to a kind of washer, refers to particularly, a kind of ultrasonic cleaner.
(2) background technology
It is that a kind of physics cleans that ultrasonic wave cleans, thereby is of wide application.As shown in Figure 1, existing ultrasonic cleaner is by ultrasonic cleaner body 1 with place the intrinsic ultrasonic output circuit plate 2 of this ultrasonic cleaner to be formed.Wherein, combination transducer 14 and the power line 15 that fixedly installs in the time switch 13 that is provided with by the rinse bath 12 on casing 11, casing top, casing surface of ultrasonic cleaner body 1, the casing bottom formed.Because above-mentioned ultrasonic output circuit plate can only produce a kind of fixed frequency, this frequency is (35～40) KHz at present.Like this, for the workpiece that is cleaned of dirt degree varies, if use the ultrasonic cleaner of single-frequency form (being fixed frequency) to clean, often cleaning is not thorough, and effect is undesirable.
(3) summary of the invention
The purpose of this utility model is to provide a kind of ultrasonic cleaner that has two or more operating frequencies at least, to satisfy the needs that are cleaned workpiece that clean the dirt degree varies, reaches desirable cleaning performance.
A kind of ultrasonic cleaner provided by the utility model, it comprises the ultrasonic cleaner body and places the intrinsic ultrasonic output circuit plate of this ultrasonic cleaner, be characterized in: describedly on the ultrasonic output circuit plate, comprise rectification circuit, filter circuit, produce the inverter circuit of high-frequency oscillation signal by DC voltage, resonance circuit and high-frequency oscillation signal is coupled to the transformer of resonance circuit, described rectification circuit output is in parallel with filter circuit, wave filter links to each other with inverter circuit, inverter circuit is elementary in parallel with transformer, and the secondary and resonance circuit of transformer is in parallel.
Above-mentioned ultrasonic cleaner, wherein, resonance circuit comprises feedback transformer, transducer and controllable impedance.
Owing to adopted above-mentioned technical solution, do not changing structure, do not increasing under the situation of volume, in limited space, finish many groups match circuit to the combination transducer, make the ultrasonic output circuit plate can produce at least two kinds of frequencies, conversion by frequency, make and be cleaned workpiece and obtain multiple cleaning way, for example, slightly wash, fine purifiation or the like, and make and produce the secondary peak power in the rinse bath, assist in removing obstinate dirt, washed the dirt of different nature that may exist on the workpiece and obtain omnibearing cleaning thereby make.
(4) description of drawings
Fig. 1 is the structural representation of ultrasonic cleaner;
Fig. 2 is the electrical block diagram of the ultrasonic output circuit plate in the utility model ultrasonic cleaner.
(5) specific embodiment
The utility model, promptly a kind of ultrasonic cleaner, it comprises ultrasonic cleaner body 1 and places the intrinsic ultrasonic output circuit plate 2 of this ultrasonic cleaner.As shown in Figure 2, on the ultrasonic output circuit plate, comprise rectification circuit 21, filter circuit 22, produce inverter circuit 23, the resonance circuit 24 of high-frequency oscillation signal and high-frequency oscillation signal be coupled to the isolating transformer 25 of resonance circuit by DC voltage.
Rectification circuit 21 outputs are in parallel with filter circuit 22, and filter circuit 22 links to each other with inverter circuit 23, inverter circuit 23 is elementary in parallel with isolating transformer 25, and resonance circuit 24 is secondary in parallel with isolating transformer 25.Described resonance circuit 24 comprises feedback transformer T
x, transducer Z and controllable impedance Lx.Controllable impedance Lx is the impedance matching inductance, and its matching value difference is different with frequency after described combination transducer Z produces series resonance.
When frequency in 38～40KHz scope, be mainly used in the more coarse workpiece of clean surface.
When frequency in 58～60KHz scope, especially be suitable for to clean precision component, little to being washed the surface of the work damage, have low noise, strong infiltration, characteristics such as penetrate by force, the effect of its degassing, deaeration, mixing is also very desirable simultaneously
When frequency in 78～80KHz scope, be mainly used in the mixing, pulverizing, extraction of two or more chemicals in the laboratory etc., 40KHz is incomparable especially for its fine and smooth effect.
The operation principle of ultrasonic output circuit plate is: urban network electricity is pressed V
iBehind rectification D and filtering C, become DC voltage, add to electronic switch BG
a, BG
bTwo ends, its center-side is passed through C
lBe coupled to high-frequency isolation transformer T, secondary output loop meets feedback transformer T respectively
xImpedance matching inductance L x connects combination transducer Z at last.This circuit is typical auto-excitation type oscillator, feedback transformer T
