Description

Second-hand-cigarette reclaims machine

Technical field

The utility model relates to a kind of intelligent cigarette smoke and detects and retracting device, and particularly a kind of second-hand-cigarette reclaims machine.

Technical background

State-owned 600,000,000 people smoke or smoke secondhand-cigarette according to investigations, and the people of smoking has only absorbed 5% in the flue gas, and other 95% be discharged in the air, become second-hand-cigarette, contaminated environment and infringement people's health; Smoke specific to the public arena, influence public order and other people health, smoke in the family,, make the not guilty particularly nearest wife and children of household become the direct victim of second-hand-cigarette, lose more than gain though satisfied the private wants.Existing general removing second-hand-cigarette equipment only mechanically flue gas from indoor directly pump to outdoor, and second-hand flue gas does not have substantial change, the equipment that can effectively change second-hand-cigarette also just uses in special occasion, the expense that it is expensive, and general family is difficult to bear.

Summary of the invention

The utility model provides the recovery machine of second-hand-cigarette in a kind of energy Intelligent Measurement and the filter cleaning air in view of the actual conditions in the life, removes second-hand-cigarette up hill and dale.

The technical scheme in the invention for solving the above technical problem is: a kind of second-hand-cigarette reclaims machine, comprise detection system, air filtering system, power circuit, power sense circuit, hardware configuration, its design feature is that power circuit output end connects power sense circuit, the power sense circuit output connects detection system, and detection system is made up of Detection Circuit, A/D converter and single-chip microcomputer; The detection system output connects air filtering system, and air filtering system comprises fan drive circuit, Electrostatic Absorption circuit, carbon monoxide decomposition circuit; Hardware configuration is made of high-temperature resistance plastice, and inner screen pack is made of electrical conductivity alloy silk closely, and an air inlet is established in the top, and side evenly has exhaust outlet.

Detection Circuit described in the utility model is made of nicotine sensor, carbon monoxide transducer.

Air filtering system described in the utility model is directly controlled output by single-chip microcomputer.

The output signal of power sense circuit described in the utility model directly arrives single-chip microcomputer.

The utility model adopts nicotine sensor and carbon monoxide transducer two-way to detect, accurately and reliably as a kind of innovative product; The self-filtering net constitutes convenient disassembly by electrical conductivity alloy silk closely; Can filter out ancient gas fourth of Buddhist nun and carbon monoxide in the cigarette, change it into activated carbon and air, purify air effectively; The utility model outward appearance novelty, gracefulness, compact conformation, simply small and exquisite, with low cost, good reliability, antijamming capability is strong, is applicable to family, office, multiple places such as public service space.

Description of drawings

Fig. 1 is a system construction drawing of the present utility model.

Fig. 2 is circuit theory diagrams of the present utility model.

The specific embodiment

Referring to Fig. 1-2, the implementation case comprises: detection system a, air filtering system b, power circuit 7, power sense circuit 8, hardware configuration, battery BT1 provide power supply to whole system, the gauge tap S1 of power circuit 7 is battery main switches, its output connects power sense circuit 8, the power filtering capacitor C1 of power sense circuit 8, C2, be used to guarantee the stable of power supply power supply, help each electronic unit steady operation and life-time dilatation, power sense circuit 8 outputs connect detection system a, and detection system a is by Detection Circuit 1, A/D converter 2 and single-chip microcomputer 4 are formed; Detection system a output connects air filtering system b, and air filtering system b comprises fan drive circuit 3, Electrostatic Absorption circuit 5, carbon monoxide decomposition circuit 6; Fan drive circuit 3 produces directed wind, thereby there being the air of flue gas to suck in; Electrostatic Absorption circuit 5 produces the filter course of a negative voltage, and the nicotine particle has positive electricity, will adsorb up, thereby reach the effect of filtration; Carbon monoxide decomposition circuit 6 produces the charged layer of a high frequency, changes the molecular structure of carbon monoxide, discharges oxygen, active atoms of carbon and AIR MIXTURES;

Hardware configuration is made of high-temperature resistance plastice, and inner screen pack is made of electrical conductivity alloy silk closely, and an air inlet is established in the top, and side evenly has exhaust outlet.Described Detection Circuit is made of nicotine sensor, carbon monoxide transducer, so just can remove the harmful substance in the flue gas comprehensively.In order to improve sensitivity, the described air filtering system b of the implementation case directly controls output by single-chip microcomputer 4.The output signal of described voltage detecting circuit directly arrives single-chip microcomputer 4.

In the implementation case when air has imflammable gas to surpass certain value, when just having the signal input, the current potential step-down of the output pin of gas sensor is by the voltage step-down on the resistance R 2 back main control chip JP1 pin 3, after voltage is lower than setting value, the main control chip gas filtration program that brings into operation; Export high level on the single-chip microcomputer 4 main control chip pin 2, start working by fan electromotor in the current-limiting resistance R3 rear drive fan drive circuit 3, filter inductance L1 is a filtering usefulness, can produce heavy current impact when fan electromotor starts, and is used to alleviate this rush of current; The pin 6 of single-chip microcomputer 4 main control chips is set to negative voltage by current-limiting resistance R5, is input to single-chip microcomputer 4 main control chips from the negative pole of power supply, produces a negative voltage on the Electrostatic Absorption layer P2 of Electrostatic Absorption circuit 5, is used for the adsorptive nicotine particle; The high-frequency signal of the pin 4 output 400KHz of single-chip microcomputer 4 main control chips, behind current-limiting resistance R4, be input to switch triode Q2, make the high frequency filter course P1 that is connected to the Q2 colelctor electrode produce the high-frequency signal of a 400KHz, airborne carbon monoxide molecule formula by the high frequency filter course is changed, discharge activated carbon, oxygen and AIR MIXTURES are to reach the purpose of filtered air.

The utility model is put in the place that table is gone up or other is often smoked, turn on the power switch, sensor just begins to detect, when the people is smoking, the content of airborne nicotine and carbon monoxide will raise, when nicotine and carbon monoxide surpass certain value, A/D converter 2 will output signal arrive single-chip microcomputer 4, single-chip microcomputer 4 will output signal arrive fan drive circuit 3, Electrostatic Absorption circuit 5 and carbon monoxide decomposition circuit 6, controlling them starts, suck waste gas, and give off the air that has activated carbon, reach the effect of filtered air; And the toxic gas of the air that has activated carbon in can absorbed air.So just can reaching purifies air removes the purpose of second-hand-cigarette.
