使用过超声波清洗设备的人，都知晓超声波清洗器工作时会发出令人感觉不舒适的声响，这种声响就是超声波清洗高频工作发出的，那人们心里就会有疑问，这样的超声波设备有辐射吗？其实这是不用担心的，虽然绝大部分电子设备都或多或少有辐射，超声波清洗机也一样有，但对人体的危害是微乎其微的，毕竟超声波不同于微波炉的微波。

People who have used ultrasonic cleaning equipment know that the ultrasonic cleaner will make uncomfortable sound when it works. This kind of sound is generated by high-frequency ultrasonic cleaning work. Then people will have questions in their hearts, do such ultrasonic equipment have radiation? In fact, there is no need to worry about this. Although most electronic devices have more or less radiation, and ultrasonic cleaning machines also have the same, the harm to human body is very small. After all, ultrasound is different from microwave in microwave oven.

启航彩超声波的传输是需要介质的，这种介质一般是水，所以通常我们要在超声波清洗机的机槽里加水。超声波清洗机是利用超声波高频振荡对水分子作用来运行的，能量也被水所吸收，因此不会对人产生什么损害。之所以发出声音，这声音并不是超声波，人是听不到超声波的。这还需要超声波清洗机的原理来解释：当超声波作用于液体中时，液体中会产生数以万计个气泡，一直爆裂，从而产生能量极大的冲击波，相当于瞬间产生了几百度的高温以及高达上千个大气压，这种现象称为“空化作用”，超声波清洗利用液体中气泡爆炸所产生的冲击波来达到冲刷和清洗工件隙缝内或外表。超声波会在液体中传播，使液体与机槽在超声频率下一起振荡，液体与清洗槽振动时都有各自的固有频率，所以人们在使用超声波机器时，会听到这种振荡中产生的“啧啧啧”的声音。刚开始可能会听不习惯，感觉不是很安心，但这是心理作用，实际上对人体并没有什么危害。

启航彩Ultrasonic transmission is the need for medium, this medium is generally water, so we usually need to add water in the tank of ultrasonic cleaning machine. Ultrasonic cleaning machine is to use the ultrasonic high-frequency oscillation of water molecules to run, energy is also absorbed by water, so it will not cause any damage to people. The reason for the sound is that the sound is not ultrasonic. People can't hear it. This also needs the principle of ultrasonic cleaning machine to explain: when the ultrasonic wave acts on the liquid, tens of thousands of bubbles will be produced in the liquid, which will burst all the time, resulting in a shock wave with great energy, which is equivalent to the instantaneous generation of hundreds of degrees of high temperature and up to thousands of atmospheric pressure. This phenomenon is called "cavitation effect". Ultrasonic cleaning uses the bubble explosion in the liquid to generate The shock wave is used to wash and clean the inner or outer surface of the workpiece. The ultrasonic wave will propagate in the liquid, which makes the liquid and the machine groove vibrate together at the ultrasonic frequency. When the liquid and the cleaning tank vibrate, they have their own natural frequencies. Therefore, people will hear the "tut tut" sound produced in the vibration when using the ultrasonic machine. At the beginning, you may not be used to listening and feel uneasy, but this is a psychological effect. In fact, it is not harmful to human body.

启航彩超声波在空气里传播的衰减率大，所以超声波对人体并不会有多大的影响。

The attenuation rate of ultrasonic wave propagation in the air is large, so the ultrasonic wave will not have much impact on the human body.

启航彩如果非要说工业超声波清洗机对人体有伤害，那则是与人体的接触问题了。在清洗机工作的时间段中，要是不带着手套就直接去接触正在工作的超声水槽里的水，则会感受到微妙的变化，会有感觉不舒服。使用者应尽量避免直接把手放在正在工作的水槽里。如果一定要接触，为了安全起见应该带上手套。若还是不太放心的话，那建议在超声波清洗机工作时，不要长时间呆在机子旁边，也要尽量少接触清洗剂。

If we have to say that industrial ultrasonic cleaning machine is harmful to human body, it is the contact problem with human body. During the working period of the cleaning machine, if you directly contact the water in the working ultrasonic water tank without gloves, you will feel subtle changes and feel uncomfortable. The user should avoid putting the handle directly in the sink. If contact is necessary, gloves should be worn for safety. If you are still not at ease, it is recommended that when working in the ultrasonic cleaning machine, do not stay beside the machine for a long time, and also try to contact the cleaning agent as little as possible.
