Abstract

The utility model concerns a sterilizing equipment, in particular to an ultraviolet radiation sterilamp which can prevent the ultraviolet radiation from hurting human body. A control circuit of the utility model consists of a singlechip, a pyroelectric infrared sensor infrared sensor and a clock chip. The utility model has two alternative on-off manners of wireless remote control and automatic program control. In the process of sterilization, if somebody approaches the sterilizing equipment mistakenly, the sterilamp can be turned off automatically, which avoids the hurt on human body effectively. The utility model has the advantages of simple operation, convenience and safety, which is applicable to the sterilization in families and public places.

Description

Automatic protection formula ultraviolet disinfection lamp

The utility model relates to a kind of germ-resistant field of disinfection by ultraviolet light that utilizes.

Ultraviolet has stronger injury effect to skin, the eyes of human body.When existing ultraviolet disinfection lamp is swarmed into the sterilization scope of sterilamp if any human body mistake in disinfecting process, can not effectively and rapidly shut sterilamp, thereby human body is come to harm.Cause that easily the eyes redness also can cause skin canceration when congested, serious.

The purpose of this utility model is a kind of ultraviolet disinfection lamp that can effectively prevent the uv damage human body of design.

This utility model has adopted electromechanical integration technology, has designed wireless remote control and automatic program control function, makes human body needn't enter the scope of disinfection by ultraviolet light light irradiation, and reaches the purpose of control sterilamp.When the human body mistake is swarmed into, detect the signal of mobile human body by pyroelectric infrared sensor, the pick off output signal of telecommunication, through amplifier amplification the becoming Transistor-Transistor Logic level that single-chip microcomputer can be discerned, whether single-chip microcomputer is discerned by the variation of differentiating level has human body close, thereby determines whether the current disinfection that carries out stops.The detection range of pick off can be regulated.

This light fixture has the function of automatic start-stop, automatic protection human body, has sterilization, germ-resistant effect.Since adopted wireless remote control and automatic program control, thus simple to operation, adopted single-chip microcomputer and pick off, so dependable performance is safe.

Switching on and shutting down have three kinds of patterns: radio remote control switch machine, artificial key switch machine, automatic time switch machine.A starting-up signal of sterilamp remains to finishing of once sterilizing process always, when preparing to begin to sterilize, will send the acousto-optic warning message, begins sterilization after information is sent 2 minutes, and disinfecting time completely then quits work.Then quit work as detecting the mobile human body signal in the disinfecting process, enter waiting state.

Be control circuit figure of the present utility model shown in the accompanying drawing, IGCT VT is connected on the live wire of quartz burner.GYT is a pyroelectric infrared sensor, when detecting mobile human body, exports faint signal, through the amplification of IC2, becomes 16 feet that Transistor-Transistor Logic level that single-chip microcomputer IC1 can discern is imported IC1.IC1 receives the outside signal of sending here, opens or closes the power supply of quartz burner according to signal.24 feet of IC1 are the signal input pin of remote-controlled start-up, and 24 feet of IC1 are the signal input pin of remote-control closedown.K1 is a mode setting button, can switch between clock adjustment, timing, normal mode of operation.K2 increases key the time, and K3 is the time decreased key, and K4 is the key of starting working, and K5 is the key that quits work.Each pattern all has the indication of LED charactron.14 feet of IC1 output high level then cuts off the power supply of quartz burner, and the 14 foot output low levels of IC1 are then opened the power supply of quartz burner.

Claims

A kind of ultraviolet disinfection lamp, it is made up of quartz burner, lamp bracket, it is characterized in that it also comprises single-chip microcomputer, pyroelectric infrared sensor, clock chip, clock chip has timing and timing function, the mobile human body signal is detected by pyroelectric infrared sensor, and the duty of sterilamp is decided by the signal of single-chip microcomputer according to rpyroelectric infrared sensor and clock chip.
