Description
Technical field
This utility model relates to household electrical appliances cleaning equipment field, particularly relates to combination frequency ultrasonic cleaning equipment.
Background technology
Ultrasound wave (Ultrasound) refers to any sound wave or vibration, and its frequency exceedes human ear and can hear
High threshold 20kHz.Ultrasound wave is widely used in various fields due to its high frequency characteristics, such as metal
Flaw detection, workpiece cleaning etc..Power ultrasonic and detection ultrasound wave can be divided into according to watt level.
The cleaning principle of power ultrasonic: the dirt of body surface is carried out by the ultrasonic wave energy propagated in a liquid
Cleaning, its principle can be explained by " cavitation " phenomenon.It is " empty that cleaning performance and ultrasound wave produce in a liquid
Change " intensity has close relationship.
Ultrasound wave is propagated in a liquid by vibration, when its pressure of sound wave reaches an atmospheric pressure, and ultrasound wave
Power density be about 0.35W/cm, the pressure of sound wave peak value of the ultrasound wave propagated the most in a liquid is the most permissible
Easily reach vacuum or negative pressure；But actually exist without negative pressure appearance, thus produce one in a liquid
The biggest power, becomes cavity (cavitation nucleus) by fluid molecule drawing crack, and this cavity is vacuum or closely vacuum.
Additionally, this cavity is when signal voltage (or ultrasound wave pressure) value reaches maximum at next half cycle, due to
The increase of ambient pressure and crushed, now fluid molecule fierceness collision produces the most powerful impulsive force, will
The dirt of cleaned material surface clashes into.
Produce the phenomenon of shock wave during these countless tiny and intensive bubbles burst to be referred to as " cavitation " and make
With.This cavitation is very easy to produce at the intersection of solid with liquid, thus for immersing ultrasonic work
The object in liquid under with has unusual cleaning action.
Further, since ultrasound wave has the strongest effect penetrating solid, the another of cleaned material can be penetrated into
Inner chamber in one side surface, and all immersion media, blind hole, slit, by cleaned material surface attachment
Dirt peels off, and reaches preferably cleaning performance.
Meanwhile, ultrasound wave also has emulsifying neutralization, can more effectively prevent the greasy dirt being cleaned out from again adhering to
It is being cleaned by object.So in the liquid that this " cavitation " effect is to immersing under ul-trasonic irradiation in object
