It may be uncommon in daily home life in the daily home of the mobile phone, but it is often used in toilet in public places. So what is the working principle of automatic induction of drying mobile phones?What are the categories of automatic induced dry mobile phones?
What are the types of automatic induced dry mobile phones
Due to the hygiene and convenience of automatic handicrafts, more and more public places have begun to use automatic dry hand, and some families also begin to use automatic hand -baking handiches.According to the installation method, automatic dry hand can be divided into two types: wall -mounted and vertical.
What is the working principle of automatic induction of dry mobile phone
Auto -sensing dry hand depends on far -infrared automatic induction work. It consists of infrared transmitters, receivers, single -stable delay switches, solid relays and hair dryers, etc., forming a simple self -inspiration multi -resonant oscillator.Effects the infrared light with a frequency of about 40kHz.When the persons hand is stretched to the bottom of the automatic baking hand, the emitted infrared rays are reflected in a part of the hand, and after being received by the photoretimensive triode, it is converted into an electrical signal of the same frequency, and then the integrated circuit is amplified, plastic, and plastic surgery, and plastic surgery, and plastic surgery, plastic surgery, and plastic surgery.After comparison, the output low -electric pulse signal is output, which then triggers the temporary state of the single -stable circuit composed of the composition, so that it outputs high levels, glow, and exchange solid -state relay to turn on.When the hand is dried away, the infrared pulse signal is lost, the high level is restored, and the single -stable circuit is quickly reset. Due to the delayed effect, the hair dryer will be automatically restored by about 10s and then the work will stop.
To put it simply: infrared detection -relay -relay -the hot air fan is close to infrared probes, the probe detects the human body signal; the logical circuit is flipped; a signal is provided to the drive circuit;Circuit restoration; stop working; wait for the next working signal.
The principle of inductive dry hand: induction is convenient and fast. It blows the evaporation speed of hot air acceleration to allow users to save time.That is, in the short period of time, use a cleaner method to evaporate the water on the users hands.This method of drying hand is cleaned than wipe with a towel, and it is not easy to infect bacteria.
What are the common problems of automatic induced dry mobile phones
1. Common problems are the names of no manufacturer, model model, waterproof grade marker, no installation, instructions, and instructions, II appliances are not standardized, rated voltage, irregular power signs, and incomplete signs.
Solution: When you need to buy it, you can first see the carefully information about the dry hand.It is also recommended to buy some big brands of dry hand, which is guaranteed after -sales and quality.
2. Exaggerate technical indicators, deception and misleading consumers (mainly concentrated in one -sided exaggeration input power); unqualified projects are closely related to the personal safety and environmental safety of users.
Solution: There are some small manufacturers own dry hand, and the technical parameters above are not in line with actual products.It is recommended to see more and more choices in this situation. In addition, judgment based on the price of dry handiches. If the price is very cheap but the dry time time is fast, then it may not match the actual parameters.
3. Do you always start the infrared dry hand?What is the reason for stopping together, sometimes it is fine, and sometimes it breaks?
Solution: Check whether the position of the infrared launch is loose, or remove it to clean it up!See if it is bad contact!
4. How to repair the dried hand with black smoke?
Solution: It may be that the wires are aging. It is recommended to open it to see. If the wire is burnt, please contact the maintenance personnel to change the scorched place or parts.However, you ca n’t continue to use it like this, otherwise it will be too dangerous, please use the problem to make a repair phone in a timely manner.
