Abstract

A resonant type ultrasonic fog dispersing device relating to a device adopting object resonance to realize fog dispersing purpose which is characterized in that ultrasonic frequency oscillation resonant with fog drops is produced by an electronic oscillation circuit. The oscillation circuit is connected with an electronic power amplification circuit. And the power amplification circuit connects with an ultrasonic transducer. Or the electronic oscillation circuit direct output connects with the ultrasonic transducer. Meanwhile, high amplitude impulse waves produced by external circuit or the oscillation circuit itself or power amplification circuit is mixed into the circuit, which transmits ultrasonic waves mixed with high-amplitude impulse waves. The fog drop resonances with the ultrasonic wave and absorbs the ultrasonic wave simultaneously. During resonance, the fog drop structure is broken or collides with each other. The broken drops float upward due to reduced weight. Fog drops collided with other drops will sink due to increased weight. Thus the device can achieve fog dispersing purpose.

Description

Resonance type supersonic-wave fog repellent device

Technical field

The utility model relates to the resonance type supersonic-wave fog repellent device that a kind of method that adopts ultrasonic wave and droplet to produce resonance reaches the fog-dispersing purpose.

Background technology

Want to reach the purpose of fog-dispersing, only way can only adopt the mode of heating at present, because space temperature is high more, the moisture content that can hold in the air is also just many more, by heating, just can make moisture content contained in the air not produce saturated phenomenon and noncondensing one-tenth droplet, thereby reach the purpose of the mist that looses.But this way is difficult to when using in the open air space temperature is raise because energy consumption is big, and acting surface is little, can only be to do to eliminate dewfall usefulness in indoor or car, so be not applied in practice.

Summary of the invention

The purpose of this utility model just is to provide a kind of acting surface big, not limited by indoor, open-air place, can concentrate and installs and the little resonance type supersonic-wave fog repellent device that consumes energy separately.

The utility model resonance type supersonic-wave fog repellent device, its principal character is the purpose that reaches enforcement by following two kinds of technical schemes, one, produces the ultrasonic frequency vibration by electronic circuit, this waveform amplifies by power amplifier, export transducer again to, converting the electric energy that vibrates to ultra sonic machinery through ultrasonic transducer can be directed or nondirectional to spatial emission.Two, produce the ultrasonic frequency vibration by electronic circuit, the obstructed overpower amplifier of this waveform amplifies, and directly exports transducer to.Frequency of oscillation is arranged in the band limits of the resonance frequency of droplet or big or small droplet.Waveform is sine wave, square wave, sawtooth waveforms or harmonic wave, implement for strengthening the effect of resonance, electronic oscillating circuit or power amplifier be designed to produce moment high-amplitude impulse wave or be synthesized to ultrasonic oscillator or power amplifier again or directly export ultrasonic transducer to by the impulse wave that pulse-generator circuit produces high-amplitude.The ultrasonic transducer functional equivalent is in a vibrator of loudspeaker or piezoelectric patches, and just hyperacoustic emission source can convert the electronic ripple by electro coupled oscillator or power amplifier output to mechanical energy, and promptly ultrasonic wave is outwards launched.

Many in common knowledge, any object all has its a fixing vibration (vibration) frequency, when a vibration frequency that vibration source took place equate with the frequency of another object or near the time, this object just resonates with vibration source, thereby this object just absorbs energy from the source of resonant excitation, when the source of resonant excitation continuously provided resonance wave, the resonance of this object just can constantly strengthen the quite fierceness that becomes.According to internet consulting to " resonance " speech, the covibration of object is when to be a kind of object frequency of oscillation of absorbing the wave of oscillation that another object produces and this wave of oscillation identical with the resonance frequency of preceding a kind of object, be that last object has absorbed the resonance wave that extraneous another object (source of resonant excitation) transmitted and a kind of special oscillatory occurences that produces, it can be from the source of resonant excitation energy of the absorption maximum of less attenuation, when resonance took place, this object was just quite big to the destructive power of self.The pedestrian who lines up to pass through as bridge and bridge floor or when with the train that passes through fast etc. resonance taking place just big bridge construction can become flexible, is finally collapsed.When house and seismic wave generation resonance, the house will rock until collapsing, when resonance took place for human body and infrasound, threat to life vibration, distortion or severe haemorrhage will appear and in the internal organ of human body, and factory also takes certain measure to eliminate the covibration that machine takes place.Pendulum and swing are exactly a covibration, as long as at this moment provide a very little power just can make eternal the keeping down of motion.Therefore, when the utility model during endlessly to the resonance frequency ultrasonic wave of droplet emission droplet, droplet is just drawn ultrasonic energy and synchronous resonance oscillations is taken place from the source of resonant excitation of the present utility model, because the utility model is except launching continuously the ultrasonic resonance ripple, also the impulse wave of moment generation high-amplitude is synthesized in the ultrasonic wave and launches simultaneously with ultrasonic wave, thereby, the energy absorption of droplet will constantly strengthen, covibration also constantly strengthens, finally, droplet takes place broken or collision mutually, broken smaller volume proportion takes place alleviate, just toward come-up.Because of the volume that bumps becomes big, proportion increases and sinks.Reach the purpose of the utility model fog-dispersing.

Description of drawings

Can form that the utility model tool type body implements basic circuit have manyly, here multi-resonant oscillating circuit further specifies to use very widely.
