Description

Electronic multi-purpose air purifier

The utility model belongs to air conditioning and ventilation field, relates in particular to a kind of indoor air-purification device.

Now, the condition of modernized live and work makes people's the nearly in life time more than 2/3rds live in indoor.Therefore, the indoor environment particularly quality of room air has confidential relation to health, along with industrial expansion, New Building Materials extensively are used, washing agent, cosmetics, the more application of flavouring agent in the life, view and admire various factors such as vegeto-animal raising, natural gas, liquefied gas, smoking, can cause room air to produce various pernicious gases, as H ₂S, HC, O ₃, benzene etc. in NOx and pollen, fine hair, peculiar smell, the smog, seriously influence the healthy of people.Improvement along with people's life, people require also urgent day by day to indoor air purification, but air cleaner, the clarifier pattern simple function of domestic production at present are simple, generally all manually start, the air that can not decontaminate timely, some sheathing material, filtering adsorbing material also can cause the secondary pollution air.

The purpose of this utility model provides a kind of air purifier of multifunction electronic.

For achieving the above object, the utility model has adopted following technical scheme: by housing, blower fan, motor, Automatic Detection and Control circuit, the infrared remote controller of mao bamboo making, power circuit, adsorption filter screen are formed, and are furnished with remote switching block, at air inlet gas sensor are set.

For making room air pure and fresh more pleasant, satisfy dry regional resident's needs, be equipped with miniature humidifier with machine, directly control by power circuit.

Further specify below in conjunction with accompanying drawing

As shown in Figure 1: housing 1 is made by the mao bamboo, easily processing, bonding, thereby can be according to the landscape of various countries, the personage makes the shell of all kinds of formulas, the front of housing has air inlet 2, gas sensor 3 is set below air inlet, adsorption filter screen is housed in the air inlet, adsorption filter screen comprises solid essence 4, sorbing material 5, disinfection filtering material 6, blower fan 7 is set in the housing, motor 8, motor is positioned at the middle part of blower fan, and selects for use the motor of high-speed high-power, electronic circuit board 9 to be contained in bottom in the housing, comprise miniature humidifier circuit board, the Automatic Detection and Control circuit board, the infrared remote control circuit board for receiving, power supply circuit board is provided with switch 10 on case panel, indicator lamp 11, the side of housing has air outlet, is furnished with dress Infrared Remote-Control Sending circuit board in the remote switching block 12 outward.

Electronic circuit part is as Fig. 2-shown in Figure 6.

Fig. 2 is the Automatic Detection and Control circuit, and gas sensor QM and variable resistor W1, capacitor C 6, resistance R 6, R7 form Detection Circuit, and thermistor Rt and capacitor C 7, variable resistor W2 form temperature sensing circuit; Be made of or gate logic diode D6, D7, triode BG4 is operated on off state.Ic chip 1 is NE555, is connected into bistable circuit, and BCR is as single-way switch.

When adopting automatic detection mode, as indoor no pernicious gas, resistance is bigger between gas-sensitive head A, B, and B point current potential is lower than 1V, and D7, BG4 do not work, and NE555 pin 6 is a high level.3 pin are low level.BCR turn-offs.Indoor if any pernicious gas, resistance reduces rapidly between A, B, makes B point current potential raise D2, BG4 conducting, clarifier machine operation.Temperature sensing circuit mainly is to remedy the deficiency of gas-sensitive head to detectivities such as stink with perspiration.

Indoor temperature is lower than 37 ℃, and thermistor Rt resistance is big, and E point current potential is lower than 1V, and the clarifier motor is not worked.In case when temperature rises to people's perspiration, both be higher than 37 ℃, the Rt resistance will reduce this moment, and at this moment E point current potential raises, and the clarifier motor gets electric work.Motor quit work when temperature dropped to 37 ℃ of left and right sides.

Fig. 3, Fig. 4 are the infrared distant circuit diagram of penetrating, and have adopted the infrared integrated circuit of selecting for use.

Among Fig. 3, adopted ic chip 2, IC2 to be special-purpose emission integrated circuit LC2190,1 pin output in-line coding signal, pulse signal outside BG5 amplification rear drive LED is rubescent.The external oscillation resistance electric capacity of 2 pin is adjusted the R15 resistance, makes the LC2190 internal oscillator be operated in 38 * 2KH2 frequency.Produce the 38KH2 carrier frequency through 2 frequency divisions again.3 pin meet timing capacitor C14 interpulse period.The external indication of 5 pin.The 8-13 pin is external coding button.The static power consumption of this circuit is less than 1uA.Need not to establish power switch.

Among Fig. 4, adopted ic chip 3, IC4, IC3 is the special-purpose integrated package CX2016 that receives, and IC4 is a drive circuit integrated package 9211.The infrared pulse signal that receives is exported by 7 pin after the IC3 inter-process, through the input of IC413 pin, in the corresponding switching signal of 1-6 end output, 8,9,10 pin are outer meeting resistance R20, R21 triode BG6-BG8 respectively after the inner interpreter code, drive relay, reach the purpose of control motor.

Fig. 5 is a power circuit diagram, and the K1 complete machine that closes is charged, and this moment, K2 was as placing manually clarifier motor D J work.

K2 then connects the public end of K3 as placing automatically, and K3 has two kinds of selections, the one, automatic detection, the one, remote control.

After transformer step-down D12-D15 rectification, provide voltage VDD1(5V for IC3, IC4 by IC 57805), provide voltage VDD2(9V by IC17809 for J1-J3).

Socket CE is located in the manual loop.

Fig. 6 is miniature humidifier circuit, and humidifier mainly is made up of oscillator, and oscillator is by inductance L 1, capacitor C 1, and triode BG1 forms, and L1, C1 determine its amplitude.

Inductance L 2, capacitor C 2 are formed positive feedback loop.

Inductance L 3 is high frequency choke coils, stops ultrasonic signal to enter dc bias circuit.Guarantee the BG1 stabilization of operating point.

During work, A is in water, and B connects shell.A, B constitute power path, for BG1 provides bias current.During anhydrous state, A, B open circuit, emitter follower is not worked, and BG1 does not have bias current, the blocking of oscillator.Reaching automatic control shuts down.During humidifier work, plug CO ₂Insert the socket C in the power circuit ₂In, K2 places manually, and clarifier, humidifier are worked simultaneously.

The complete machine operation principle is as follows: connect power supply, and the input service signal, blower fan rotates at a high speed, because the blade action of centrifugal force produces kinetic energy, force air is sent from the air channel, and forms vacuum in the middle part; Because atmospheric pressure and vacuum have formed the pressure reduction outside air and can suck in the blower fan in a steady stream naturally.Make air produce the circulation of convection current like this, because certain pressure reduction is partly arranged advancing air, generally at the 10mm water column, the adsorption filtration sterilization material can be placed in the fan air inlet front, must adsorb and this three phases of filter sterilization before making air enter blower fan, thereby reach the purpose that purifies air.It is the efficient purifying and sterilizing material of KJC-III type that promise this purification techniques Research Institute in Beijing is produced that the utility model adopts scavenging material.

Advantage of the present utility model:

1, be to adopt physical filtering to air cleaning, absorption, no secondary chemical reaction do not have any pair of effect to human body.

2, shell is to manufacture with the mao bamboo, rather than common plastic products, non-secondary pollution.

3, multiple functional, be convenient for people to use.
