How Do You Understand The Workings Of A Dry Cell Phone?
Nov 27, 2017

The working principle of the dry cell phone is generally detected by the sensor (hand), this signal looks at the control to turn on the heating circuit relay and the hair-dryer relay, starts to heat, the hair. When the sensor detects the signal disappears, release the contact point, the heating circuit and the blower circuit relay disconnect, stops heating, the hair.

Heating device has no heating device, PTC, electric wire.

1, no heating device, as the name implies no heating device

Suitable for places where the temperature is more demanding, and where the mobile phone is used frequently,

For example: frozen vegetables, frozen dumplings packaging workshop

2, PTC Heating

PTC thermistor Heating, because as the ambient temperature changes, the power of PTC heating also changes, in the winter when PTC heating power increased, dry cell phone blowing warm air temperature rise also increased, energy saving and environmental protection.

PTC is characterized by good temperature constancy, but there is also a certain disadvantage, that is, no electric wire temperature up fast.

3, Heating wire

Traditional electric heating wire, the wind temperature rise fast, but the wind temperature constant, easy wind temperature high, opponents have burns.

High-speed dry cell phone using a heating wire and CPU with temperature sensor control, to achieve the wind temperature rise fast and constant effect, even if the wind speed up to 100 m/s, dry phone can also blow out a constant Wen Feng.
