Description

Microphone ozone sterilization deodoriser

This utility model relates to a kind of device that utilizes electronic technology generation ozone to carry out disinfection and sterilize with microphone.

Because " Karaoke " of self-recreation universal, microphone has been not only the special apparatus of performer on the stage in recent years.But,, use frequent because personnel mix at present in various entertainment places, microphone is subjected to the pollution of pathogenic bacteria unavoidably, not only is stained with saliva on the microphone, and handle also can be stained with pathogenic bacteria after handling because of many people, and most day room, dining room all are by lighting, lose sunlight all day, so long-term, be that stain is full of stains or spots on the microphone, send undesirable abnormal flavour, though someone adopts the disinfectant solution microphone to wipe examination, bactericidal effect is poor, and what have also can damage microphone.

Chinese patent also disclosed some microphone ozone sterilization devices, but the weak point that exists is can only the sterilizing microphone mouth, and handle can not be sterilized, and circuit structure is unreasonable, automatically control time and ozone concentration.

The purpose of this utility model provide a kind of simple in structure, easy to operate, can control automatically, microphone ozone sterilization deodoriser that Disinfection Effect is good.

This utility model is realized in following mode: microphone ozone sterilization deodoriser comprises ozone generating pipe, microphone holder, control circuit board and casing, be characterized in control circuit board, ozone generating pipe, microphone fixed mount or pallet are placed in the casing, time switch and on and off switch are equipped with in the casing side, control circuit board comprises transformation, rectification and filter circuit, selector switch and timing circuit, ac oscillator circuit, the connected mode of circuit is earlier through rectification from mains transformer input back, receive relay normally open contact behind the filter circuit respectively, the moving point of timing selecting switch and the power end of timing circuit, the fixed point of switch is selected in the trigger end selecting of timing circuit, and with connect power supply negative terminal after electric capacity is connected, timing circuit starting termination button switch, join with relay coil behind the output termination audion, the power end of another termination agitator of relay normally open contact, the outfan of agitator connects the elementary of booster transformer behind audion, transformer secondary output connects ozonizer, the triggering termination power supply negative terminal of agitator.

Above-mentioned said selector switch and timing circuit are for selecting the circuit of working time with many blocked resistances switch; High-frequency oscillating circuits provides platform suitable high-frequency voltage signal for ozone generating pipe; Ozone generating pipe is with airborne O by high pressure ₂Become O ₃, to reach the sterilization purpose.

The operation principle of control circuit is: switch presses button, the timing circuit conducting, relay work, the normally opened contact closure, thus make the high-frequency oscillating circuits energising, and the output high frequency electric is to booster transformer, add the high pressure of 1500-2000 volt at the ozone generating pipe two ends, ozone generating pipe produces high-concentrated ozone, can carry out disinfection by microphone, and disinfecting time can be regulated the timing circuit ON time by selector switch.

The utlity model has following advantage:

1. microphone carries out disinfection at regular time and quantity, does not choose and waits on the machine side.

2. Disinfection Effect is good, and the casing volume is bigger, can talk with nozzle and handle and carry out comprehensive sterilization, can not damage microphone.

3. easy to operate, can be put in the day room during use and plug in, put into microphone, opening switch can carry out disinfection.

4. put into pallet, can also carry out disinfection other article such as tablewares such as cup, chopsticks.

Below in conjunction with accompanying drawing enforcement structure of the present utility model is described.

Fig. 1 is the mechanical construction drawing of microphone ozone sterilization deodoriser;

Fig. 2 is the electrical schematic diagram of microphone ozone sterilization deodoriser.

See from Fig. 1, control circuit board 2, ozone generating pipe 3 are housed in the casing 1 of microphone ozone sterilization deodoriser, and be provided with microphone fixed mount 4, microphone 5 is placed on the microphone fixed mount, and there are time switch 7 and on and off switch 8 in the side of casing 1, and cover plate 6 is arranged at the top.

From Fig. 2, see, 220 volts of alternating currents from transformator A blood pressure lowering input after bridge rectifier and C1R1 filtering, receive the coil of relay J respectively, the relay J normally opened contact, with the power end of the moving point of timing selecting switch KW and timing circuit ic chip 1 8. and 4., the trigger end of IC1 7. and 6. selecting is selected the moving some R4 of K switch W, R5, R6,1. the other end of IC1 connects power cathode, 5. after capacitor C 3, also be connected with power cathode, 2. starting end meets button switch S, 3. outfan is connected with the coil of relay J behind audion T1, IC1 can select NE555 integrated circuit or normal transistor delay circuit for use, 8. and 4. the power end of another termination agitator IC2 of relay J normally opened contact, the trigger end of IC2 2., 6. connect power cathode through

capacitor C

4,1. and 5. negative terminal also connects power cathode respectively and connect power cathode after capacitor C 5,3. the outfan of IC2 meets booster transformer B behind audion T2 diode D2 elementary, the secondary ozone generating pipe G that connects.

In circuit, be connected to after the rectification of power supply transformation between light emitting diode L2, audion T1 and the relay J coil and also be connected to light emitting diode L1.

IC2 also can select NE555 integrated circuit or transistor oscillating circuit for use, and when having ready conditions, IC2 and audion T2 also can make whole integrated package (module).

The operation principle of structure is implemented in summary again:

220 volts of alternating currents from transformator A blood pressure lowering input after behind the bridge rectifier, capacitor C 1 filtering, the normally opened contact of No. one cut-in relay J, another road through resistance R 1 connect respectively IC1 the 4., 8. foot, the moving point of K switch W, resistance R 7, resistance R 8.IC1 4., 8. foot is a power end, IC1 has just had running voltage like this.The trigger end that one of R4, the R5 that electric current connects from KW, three resistance of R6 flow into IC1 6., 7. foot and capacitor C 2, to select the working time of IC1.It is working properly to light light emitting diode L2 indicating circuit through the electric current of resistance R 8.IC1 2. foot be starting end, be that high level triggers, switch S ground connection at ordinary times is when needs work, press switch S, electric current flows into the 2. foot of IC1 from R7, and IC1 is started to work, this moment IC1 3. foot output high level of outfan the, electric current is through resistance R 3 turn-on transistor T1, like this, just there is electric current to pass through relay J, resistance R 2, and light light emitting diode L1, the inner normally opened contact adhesive of relay, electric current through relay contact flow into IC2 the 4., 8. foot provides working power, IC2 and resistance R 9, R10, capacitor C 4 constitutes agitator, high-frequency sasser can constantly make audion T2 conducting through resistance R 11 from the 3. foot output of IC2, ends, make the elementary of booster transformer B have high frequency electric to flow through, B's is secondary, it is identical to induce frequency, and more than 100 times the voltage of raising is added in the two ends of ozonizer G.When the IC1 timing arrives, the 1. foot output low level, audion T1 ends, not adhesive of relay J, IC2 is because of the two ends no-voltage of no current failure of oscillations ozonizer G.
