在生活和工業生產中，清洗是一項必不可少的工作。從精密的電子元件到日常的眼鏡首飾，從復雜的機械零件到各類光學儀器，清洗的質量直接影響著產品的性能和使用壽命。而超聲波清洗機，憑借其獨特的清洗原理和高效的清洗效果，正逐漸成為清洗領域的 “明星產品”。

Cleaning is an essential task in both daily life and industrial production. The quality of cleaning directly affects the performance and service life of products, from precision electronic components to everyday eyewear and jewelry, from complex mechanical parts to various optical instruments. Ultrasonic cleaning machines, with their unique cleaning principles and efficient cleaning effects, are gradually becoming the "star products" in the cleaning field.

一、發展歷程：從理論到應用的跨越

1、 Development process: a leap from theory to application

超聲波清洗技術的發展可以追溯到 20 世紀初。1914 - 1918 年，朗之萬發明了夾心壓電換能器，為超聲波技術的發展奠定了基礎。20 世紀 20 年代，梅森發明變幅桿，與換能器連接可產生高強度超聲波振動。30 年代，美國無線電公司技術人員提出超聲波清洗技術。中國的超聲波清洗器件起始于 50 年代初，最初主要應用于電子、光學和醫藥等領域。隨著技術的不斷發展，70 - 80 年代，美國及歐洲將超聲波技術廣泛運用到工業生產上。90 年代后期，超聲波清洗設備種類繁多，技術逐漸走向成熟，高頻超聲波清洗設備的占比也越來越高。

The development of ultrasonic cleaning technology can be traced back to the early 20th century. In 1914-1918, Langevin invented the sandwich piezoelectric transducer, laying the foundation for the development of ultrasonic technology. In the 1920s, Mason invented a variable amplitude rod that, when connected to a transducer, can generate high-intensity ultrasonic vibrations. In the 1930s, American radio company technicians proposed ultrasonic cleaning technology. China's ultrasonic cleaning devices began in the early 1950s and were initially mainly used in fields such as electronics, optics, and medicine. With the continuous development of technology, in the 1970s and 1980s, the United States and Europe widely applied ultrasonic technology to industrial production. In the late 1990s, there were various types of ultrasonic cleaning equipment, and the technology gradually matured. The proportion of high-frequency ultrasonic cleaning equipment also increased.

二、工作原理：神奇的 “空化效應”

2、 Working principle: magical "cavitation effect"

超聲波清洗機的工作原理主要基于超聲波的 “空化效應”。超聲波是頻率高于 20000 赫茲的聲波，它具有方向性好、穿透能力強、易于獲得較集中聲能的特點。當超聲波在液體中傳播時，會使液體中的微氣泡在聲波的作用下保持振動。在減壓力作用時，液體中產生真空核群泡；在壓縮力作用時，真空核群泡受壓力壓碎產生強大的沖擊力，這種沖擊力能夠剝離被清洗物表面的污垢，達到精密洗凈的目的。

The working principle of ultrasonic cleaning machine is mainly based on the "cavitation effect" of ultrasonic waves. Ultrasonic waves are sound waves with frequencies higher than 20000 hertz, which have the characteristics of good directionality, strong penetration ability, and easy acquisition of concentrated sound energy. When ultrasound propagates in liquid, it causes microbubbles in the liquid to remain vibrating under the action of sound waves. When the pressure is reduced, vacuum nucleus bubbles are generated in the liquid; When subjected to compressive force, the vacuum core bubble is crushed by pressure to generate a strong impact force, which can peel off the dirt on the surface of the cleaned object and achieve precise cleaning.

除了空化作用，超聲波在液體中還會產生直進流作用和加速度作用。直進流可使被清洗物表面的微油污垢被攪拌，促進污垢表面清洗液的對流，加快溶解污物的溶解液與新液的融合，對污物起到搬運作用。對于頻率較高的超聲波清洗機，加速度作用則靠液體粒子在超聲作用下的加速度撞擊粒子對污物進行超精密清洗。

In addition to cavitation, ultrasound also produces direct flow and acceleration effects in liquids. Direct flow can stir the micro oil dirt on the surface of the cleaned object, promote the convection of the cleaning solution on the dirt surface, accelerate the fusion of the dissolved liquid and the new liquid, and play a role in transporting the dirt. For high-frequency ultrasonic cleaning machines, the acceleration effect relies on the acceleration of liquid particles under ultrasonic action to collide with particles for ultra precision cleaning of dirt.

三、結構組成：三大模塊協同工作

3、 Structure composition: Three major modules work together

最簡單的超聲波清洗設備由超聲波發生器、換能器和清洗槽三個模塊構成。

The simplest ultrasonic cleaning equipment consists of three modules: ultrasonic generator, transducer, and cleaning tank.

超聲波發生器的作用是產生并向換能器提供超聲能量，將市電轉換成與超聲波換能器相匹配的高頻交流電信號。它就像是超聲波清洗機的 “心臟”，為整個清洗過程提供動力支持。其頻率自動跟蹤和振幅控制特性至關重要，能根據負載和工具磨損情況調整輸出功率，保證清洗質量并保護超聲系統。

The function of an ultrasonic generator is to generate and provide ultrasonic energy to the transducer, converting the mains power into high-frequency AC signals that match the ultrasonic transducer. It is like the "heart" of an ultrasonic cleaning machine, providing power support for the entire cleaning process. The automatic frequency tracking and amplitude control characteristics are crucial, as they can adjust the output power according to the load and tool wear, ensuring cleaning quality and protecting the ultrasonic system.

換能器主要將超聲波發生器輸入的電功率轉化成高強度的機械振動功率傳遞到清洗槽。在大功率超聲波清洗機中，常采用多個換能器組合組成換能器陣列，以提高聲電效率，加強清洗效果。常見的換能器有壓電換能器和磁致伸縮換能器。

The transducer mainly converts the electrical power input by the ultrasonic generator into high-intensity mechanical vibration power and transmits it to the cleaning tank. In high-power ultrasonic cleaning machines, multiple transducers are often combined to form a transducer array to improve acoustic and electrical efficiency and enhance cleaning effectiveness. Common transducers include piezoelectric transducers and magnetostrictive transducers.

清洗槽通常使用不銹鋼鋼板做成，換能器和清洗槽粘連處的鋼板不能太厚，否則會減少聲能損失，粘貼面需做磨砂處理，以確保換能器和清洗槽壁牢牢粘貼。而清洗槽內壁與清洗液接觸，要進行拋光處理，減少對清洗槽的空化腐蝕。

The cleaning tank is usually made of stainless steel plate. The steel plate at the junction of the transducer and the cleaning tank should not be too thick, otherwise it will reduce the loss of sound energy. The bonding surface needs to be sandblasted to ensure that the transducer and the cleaning tank wall are firmly adhered. When the inner wall of the cleaning tank comes into contact with the cleaning solution, it needs to be polished to reduce cavitation corrosion of the cleaning tank.

四、分類多樣：滿足不同需求

4、 Diverse categories: meeting different needs

根據用途的不同，超聲波清洗機可分為工業用、商用、實驗室用和家用超聲波清洗機。工業用超聲波清洗機主要用于機械零部件、電子元件等的清洗，具有功率大、清洗效率高的特點；商用超聲波清洗機常用于眼鏡店、珠寶店等，清洗一些小型物品；實驗室用超聲波清洗機對清洗精度要求較高，可滿足科研實驗中的清洗需求；家用超聲波清洗機則操作簡單、體積小巧，適合清洗日常的餐具、水果、眼鏡等。

According to different purposes, ultrasonic cleaning machines can be divided into industrial, commercial, laboratory, and household ultrasonic cleaning machines.

按自動化程度，又可分為全自動、半自動和手動超聲波清洗機。全自動超聲波清洗機可實現一鍵操作，自動完成清洗、漂洗、干燥等一系列流程；半自動超聲波清洗機需要人工輔助完成部分操作；手動超聲波清洗機則主要依靠人工控制清洗過程。

According to the degree of automation, it can be divided into fully automatic, semi-automatic, and manual ultrasonic cleaning machines. The fully automatic ultrasonic cleaning machine can achieve one click operation, automatically completing a series of processes such as cleaning, rinsing, drying, etc; The semi-automatic ultrasonic cleaning machine requires manual assistance to complete some operations; Manual ultrasonic cleaning machines mainly rely on manual control of the cleaning process.

此外，還可按容量、槽體數量、使用的清洗劑等進行分類，不同類型的超聲波清洗機滿足了各行各業多樣化的清洗需求。

In addition, ultrasonic cleaning machines can be classified according to capacity, number of tanks, and cleaning agents used. Different types of ultrasonic cleaning machines meet the diverse cleaning needs of various industries.
