1、 加熱膜與電路板的連接斷開；
1. The heating film is disconnected from the circuit board;
2、 設置溫度低于實際溫度；
2. The set temperature is lower than the actual temperature;
3、 加熱膜燒壞；
3. The heating film is burnt out;
4、 控制面板溫度設置模塊失效。
4. The control panel temperature setting module has failed.
造成超聲波清洗機不加熱有哪些因素
What factors cause the ultrasonic cleaner not to heat
針對這些可能的原因，我們可以通過以下的方式判斷和處理。
For these possible causes, we can judge and deal with them in the following ways.

1、 查看加熱膜與電路板連接的線路是否有斷開，如果有，可以自行連接起來再測試即可；
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、 當你設置的溫度低于液體的實際溫度時，加熱功能是不開啟的?？梢詸z查一下自己設置的溫度是多少，并提高設置溫度過后再測試加熱功能是否正常啟用。
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、 加熱膜一般覆蓋在清洗槽外表面，可以觀看一下是否出現(xiàn)燒壞的現(xiàn)象。如果是加熱膜燒壞，需要聯(lián)系廠家更換維修。
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，有可能的就是控制面板出問題。
4. If the above reasons are eliminated, the most likely problem is the control panel.
如果說超聲波清洗機對人體有傷害，則是與人體的接觸問題。在清洗的過程中，如果不帶手套直接接觸正在工作的超聲波清洗機水槽里的水，則會感受到微秒的變化，不舒服。那么應盡量避免直接把手放在正在工作的水槽里。如果無法避免，好帶上手套。若還是不太放心的話，那就不要長時間呆在超聲波清洗機旁，也盡量少接觸清洗劑。
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.
超聲波清洗機對人身體到底有沒有傷害?超聲波清洗是利用超聲波在液體中的空化作用,加速度作用及直進流作用對液體和污物直接,間接的作用,使污物層被分散,乳化,剝離而達到清洗目的.只是聲波的一種,本身不會造成對人體的傷害。
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.
