1、 加热膜与电路板的连接断开；
1. The heating film is disconnected from the circuit board;
2、 设置温度低于实际温度；
2. The set temperature is lower than the actual temperature;
3、 加热膜烧坏；
3. The heating film is burnt out;
4、 控制面板温度设置模块失效。
4. The control panel temperature setting module has failed.
造成超声波清洗机不加热有哪些因素
What factors cause the ultrasonic cleaner not to heat
针对这些可能的原因，我们可以通过以下的方式判断和处理。
For these possible causes, we can judge and deal with them in the following ways.

1、 查看加热膜与电路板连接的线路是否有断开，如果有，可以自行连接起来再测试即可；
1. Check whether the circuit between the heating film and the circuit board is disconnected. If yes, you can connect it yourself and test again;
2、 当你设置的温度低于液体的实际温度时，加热功能是不开启的。可以检查一下自己设置的温度是多少，并提高设置温度过后再测试加热功能是否正常启用。
2. When the temperature you set is lower than the actual temperature of the liquid, the heating function is not turned on. You can check the temperature set by yourself, and test whether the heating function is normally enabled after the set temperature is raised.
3、 加热膜一般覆盖在清洗槽外表面，可以观看一下是否出现烧坏的现象。如果是加热膜烧坏，需要联系厂家更换维修。
3. The heating film is generally covered on the outer surface of the cleaning tank to see if it is burnt out. If the heating film is burnt out, contact the manufacturer for replacement and maintenance.
4、 如果排除了上述的原因后，有可能的是控制面板出问题。
4. If the above reasons are eliminated, the most likely problem is the control panel.
如果说超声波清洗机对人体有伤害，则是与人体的接触问题。在清洗的过程中，如果不带手套直接接触正在工作的超声波清洗机水槽里的水，则会感受到微秒的变化，不舒服。那么应尽量避免直接把手放在正在工作的水槽里。如果无法避免，好带上手套。若还是不太放心的话，那不要长时间呆在超声波清洗机旁，也尽量少接触清洗剂。
If the ultrasonic cleaner is harmful to human body, it is a problem of contact with human body. During the cleaning process, if you do not wear gloves and directly contact the water in the water tank of the working ultrasonic cleaner, you will feel microsecond changes and feel uncomfortable. Then try to avoid putting your hands directly in the working sink. If unavoidable, wear gloves. If you are still worried, don't stay near the ultrasonic cleaner for a long time, and try to contact less detergent.
超声波清洗机对人身体到底有没有伤害?超声波清洗是利用超声波在液体中的空化作用,加速度作用及直进流作用对液体和污物直接,间接的作用,使污物层被分散,乳化,剥离而达到清洗目的.只是声波的一种,本身不会造成对人体的伤害。
Is there any harm to human body caused by ultrasonic cleaning machine? Ultrasonic cleaning is to use the cavitation, acceleration and direct inflow of ultrasound in the liquid to directly and indirectly affect the liquid and dirt, so that the dirt layer can be dispersed, emulsified and peeled off to achieve the purpose of cleaning. It is just a kind of sound wave, which will not cause harm to human body itself.
