Relay connects to the collector of transistor

Relay connects to the collector of transistor. When the current drives, the switch is closed, then the solenoid valve is energized, then the circuit is closed, then hair dryer blow air. While there is not having the current, Blade Hand Dryers the switch is turned off, then the solenoid valve is not energized, then the circuit is disconnected, then hair dryer does not blow hot air. At the same time, a diode acrosses the relay parallel protection. Light-emitting diode in the circuit is a display, commercial hand dryer showing hair dryer stsrted

automatically turned off

jet hand dryer circuit consists of five parts; the infrared transmitter circuit, infrared receive circuit, time delay circuit, hair dryer switch circuit and power circuit. In the infrared transmitter circuit, the output circuit terminal Q generates a pulse signal to control the light-emitting diode emits light pulses at, in addition, the diode from the role of protecting the infrared light emitting diode. The transistor cuts, no current flows through, Stainless Steel HandDryer in the time delay and hair dryer switch circuits, when the output Q outputs low.

Relay connected to the collector of the transistor

Relay connected to the collector of the transistor, High Speed Hand Dryers when a current is driven, pull switch, solenoid valve is energized, the circuit is closed, hair dryer blowing wind; when there is no current drive, switch off, the solenoid valve is not energized, the circuit is broken, do not blow a hair dryer wind. At the same time the relay ends of a diode in parallel to achieve protection, added a light emitting diode in the circuit as a display circuit, auto hand dryers which shows whether a hairdryer start

Dry hands fast

Dry hands fast, eco-friendly hand dryers is mainly wind, heat-assisted dry hands. This hand dryer is characterized by a high wind speed, the water will soon hand blown off, but the heating function is to keep hands warm comfort usually winds between 35-40 degrees. In the fast dry hands, while there will be no burning sensation, color is mainly personal preference and the overall mix of environmental issues, there is food factories, pharmaceutical companies, etc. try to choose materials primaries jet hand dryers, because paint dry hands there may be volatile, it would affect the safety of food or medicine

best choice for dry hands

Optional dry hands should also pay attention to the motor hand dryer which uses a form. Used motor best Hand Dryers in many forms, there are capacitor asynchronous motors, shaded pole motors, series motors, DC motors, permanent magnet motors and the like. Capacitor asynchronous motors, shaded pole motors, DC motors driven hand dryer has the advantage of low noise, and series motors, permanent magnet motor drive and Airjet Hand Dryers with a large amount of wind advantage, and now the latest brushless DC motor combination the above characteristics, low noise, air volume, has become now the best choice for dry hands

Buying Guide

When you purchase automatic hand dryer, consumers should be according to their needs and environment situation to decide which one to buy dry hands. PTC type of dry hands, and electric wire type of dry hands are different. Consumers also can according to their needs, choose to wind-based, supplemented by the air flow type heat dry hands, or with a hot air type heat mainly dry hands. In the selection of electromagnetic induction type dry hands, it should pay attention to this dry hands susceptible to environmental and articles. Selected infrared induction hand dryer should be noted that the infrared sensor type power hand dryer is also susceptible to interference of light, when consumers buy time to conduct the test machine, selecting less susceptible to interference dry hands
