Abstract
The utility model relates to an automatic circulating and purifying device of air comprising a power supply unit, a air-sensitive sensing unit, a switch unit and an air exhaust unit, wherein the power supply output end of the power supply unit is connected with the air-sensitive sensing unit and the power supply input end of the switch unit, the signal output end of the air-sensitive sensing unit is connected with the control signal input end of the switch unit, and the control signal output end of the switch unit is connected with the power supply end of the air exhaust unit. Since the air-sensitive sensing unit monitors the current air condition in real time, when the concentration of contaminant in air is higher and higher till the air-sensitive sensing unit moves to output control signals to the switch unit, the switch unit switches on the power supply of the air exhaust unit, the power supply of the air exhaust unit is disconnected to stop working after the air exhaust unit starts air circulation and purification when reaching the action threshold value of the air-sensitive sensing unit. And therefore, the automatic circulating and purifying device of air can open the air exhaust unit to work when air foul reaches a certain degree, thereby reaching the purpose of accelerating circulation and purifying air.
Description
Technical field
The utility model relates to the automatic circulating purifying device of a kind of air.
Background technology
At present, the box-type substation work under bad environment, there is the situation that dust is floating, air is dirty in the case in majority, and transformer station's pollution level is with the insulation degree between the direct relation electrical equipment, and the gas dirt is to cause one of major reason of transformer station's electric fault.
The utility model content
The purpose of this utility model provides the automatic circulating purifying device of a kind of air.
The automatic circulating purifying device of a kind of air, wherein: this device comprises power supply unit, air-sensitive sensing cell, switch element, air exhaust units, wherein, the power supply output of power supply unit connects air-sensitive sensing cell, switch element power supply input, the signal output part of air-sensitive sensing cell connects the control signal input of switch element, and the control signal output of switch element connects the feeder ear of air exhaust units.
The automatic circulating purifying device of described air, wherein: comprise a gas sensory pipe in the described air-sensitive sensing cell.
The automatic circulating purifying device of described air, wherein: described gas sensory pipe adopts HQ-II.
The utility model adopts technique scheme will reach following technique effect:
The automatic circulating purifying device of air of the present utility model, monitor current air regime in real time by the air-sensitive sensing cell, when air cleaning, the air-sensitive sensing cell keeps current state, pollutant levels are more and more higher in air, up to the action threshold value that arrives the air-sensitive sensing cell, at this moment, the action of air-sensitive sensing cell, to switch element output control signal, switch element is connected the power supply of air exhaust units, and air exhaust units is started working, after air circulation purifies, in the time of under the action threshold value of arrival air-sensitive sensing cell, the air-sensitive sensing cell recovers original non-action state, and switch element resets, the power supply of air exhaust units disconnects, and quits work.As fully visible, the automatic circulating purifying device of air of the present utility model can be opened air exhaust units work, thereby reach the purpose of quickening circulation, purifying air when the air dirt be arrived to a certain degree.
Description of drawings
Fig. 1 is the circuit theory diagrams of the automatic circulating purifying device of the utility model air.
The specific embodiment
Embodiment:
The automatic circulating purifying device of a kind of air, as shown in Figure 1: this device comprises rectifier bridge VD1 ~ VD4 (IN4007*4), voltage-stablizer U (78L05), gas sensory pipe HQ, switch triode VT (9013), load cell LSE, relay K, ventilating fan M, wherein, the input 1 of rectifier bridge VD1 ~ VD4,3 pin connect two lines of 220V mains-supplied power supply respectively, its output 2, between 4 pin and be connected to filter capacitor C2 and steering diode VS1, the output of steering diode VS1 connects input 1 pin of voltage-stablizer U by resistance R 1, input 3 pin of voltage-stablizer U connect feeder ear 1 pin of gas sensory pipe HQ, output 2 pin of gas sensory pipe HQ connect the base stage of switch triode VT by an adjustable resistance RP, the emitter stage of switch triode VT connects 1 pin of load cell LSE, the colelctor electrode of switch triode VT connects 2 pin of load cell LSE, the 3 pin feeder ears of load cell LSE connect the output of steering diode VS1, the coil that is connected relay K between the 4 pin outputs of load cell LSE and the ground, the normal opened contact K-1 of relay K are connected being connected in series on the loop of ventilating fan M and 220V mains-supplied power supply.
Described gas sensory pipe adopts HQ-II.
The 220V mains supply is rectified into dc source through rectifier bridge VD1 ~ VD4, this dc source is again through filter capacitor C2 filtering, steering diode VS1 guiding, be carried in the feeder ear of voltage-stablizer U, load cell LSE, voltage-stablizer U is to gas sensory pipe HQ power supply, so that it accurately monitors current air situation; The break-make of the output signal control triode VT of gas sensory pipe HQ, when air pollutants reach finite concentration, gas sensory pipe HQ action, its output will be exported high level signal, to drive triode VT conducting; After the triode VT conducting, output 4 pin of load cell LSE will be exported high level signal, and the coil of relay K gets electric, its normal opened contact K-1 adhesive, and ventilating fan M just can get electric work.
