Description
Technical field
The present invention relates to household electrical appliances cleaning equipment fields, more particularly to combination frequency ultrasonic cleaning equipment.
Background technique
Ultrasonic wave (Ultrasound) refers to any sound wave or vibration, and frequency is more than the highest that human ear can hear
Threshold value 20kHz.Ultrasonic wave is widely used in various fields due to its high frequency characteristics, such as metal defect detection, workpiece cleaning etc..
Power ultrasonic and detection ultrasonic wave can be divided into according to watt level.
The cleaning principle of power ultrasonic：The ultrasonic energy propagated in a liquid cleans the dirt of body surface,
Its principle can be used " cavitation " phenomenon to explain." cavitation " intensity that cleaning effect and ultrasonic wave generate in a liquid has close pass
System.
Ultrasonic wave is propagated in a liquid by vibration, when its pressure of sound wave reaches an atmospheric pressure, the power of ultrasonic wave
Density is about 0.35W/cm, and the pressure of sound wave peak value for the ultrasonic wave at this moment propagated in a liquid can easily reach vacuum or negative
Pressure；It but is actually thus to generate a very big power in a liquid without existing for negative pressure appearance, by fluid molecule drawing crack at sky
Hole (cavitation nucleus), this cavity are vacuum or very close vacuum.
In addition, the cavity in signal voltage (or ultrasonic wave pressure) value when next half cycle reaches maximum, due to surrounding
The increase of pressure and be crushed, fluid molecule fierceness collision at this time generates very powerful impact force, by cleaned body surface
Dirt hit.
The phenomenon that generating shock wave when these countless tiny and intensive bubbles bursts is referred to as " cavitation " effect.It is this
Cavitation is very easy to generate in the intersection of solid and liquid, thus the object in the liquid for immersing under ultrasonication
There is unusual cleaning action.
In addition, due to ultrasonic wave have the function of it is very strong penetrate solid, the other side table of cleaned material can be penetrated into
Face and all inner cavities immersed in medium, blind hole, slit, the dirt that cleaned material surface is adhered to peel off, and reach preferable
Cleaning effect.
Meanwhile ultrasonic wave also emulsifies neutralization, can more effectively prevent the greasy dirt being cleaned out to be re-attached to clear
On washing part.So this " cavitation " effect is to object surfaces externally and internally in the liquid immersed under ultrasonic wave effect, such as pipe fitting, case
Body part etc. can be cleaned, this is the importance that ultrasonic cleaning is better than other cleaning means.
Currently, the main devices of ultrasonic cleaning apparatus in the market are to be glued at the ultrasonic wave vibration of cleaning container bottom

1, single fixed frequency, the fixed vibration frequency of energy converter, cavitation is inadequate and easy row is at standing wave, causes to clean
It is ineffective.
2, using the powerful ultrasonic transducer of large volume, transformer uses magnetic core framework structure, influences entire ultrasound
Wave cleaning equipment, so that its volume is bigger than normal.
3, cleaning efficiency is low, and same cleaning efficiency is difficult to keep in the different depth of water.
