Abstract
The utility model discloses an automatically turned-on exhaust fan, comprising an exhaust fan, wherein an infrared gas sensor is arranged on the exhaust fan; and a power switch of the exhaust fan is connected with the gas sensor through a conductive wire. When people use a coal gas water heater to shower, if the coal gas is insufficiently burnt in the coal gas water heater and the gases such as carbon monoxide are released, the infrared gas sensor can detect the gases such as the carbon monoxide; at the moment, the infrared gas sensor triggers the power switch of the exhaust fan, thus enabling the exhaust fan to automatically start and operate; in such a way, the people are prevented from suffering carbon monoxide poisoning resulting in a threat to life due to forgetting to turn on the exhaust fan during the use of the coal gas water heater for shower; moreover, the infrared gas sensor and an instrument are widely applied, are applicable for monitoring almost various gases, and have the remarkable advantages of high precision, good selectivity, high reliability, no poisoning, no dependence on oxygen, less factors of environmental disturbance, long service life and the like; and in addition, the infrared gas sensor and the instrument gradually become a market main stream in the future.
Description
Technical field
The utility model relates to a kind of ventilating fan, relates in particular to a kind of ventilating fan of automatic unlatching.
Background technique
Ventilating fan drives fan blade rotary actuation air-flow by power switch, makes a class air adjustment electricity-saving appliance of indoor and outdoor air exchange.Claim again ventilation fan.The purpose of exhaust is exactly to remove indoor vitiated air, regulates temperature, humidity and sensory effect.Ventilating fan is widely used in family and public place.
Ventilating fan is be applied in the bathroom especially more.People are when using the gas hot-water apparatus shower, and coal gas because of can't fully burning, disengages carbon monoxide sometimes, and when forgetting out ventilating fan by chance, people are the inspiration carbon monoxide in a large number, can cause carbon monoxide poisoning, gently then dizziness, uncomfortable, heavy then entail dangers to life.
The model utility content
The purpose of this utility model provides a kind of ventilating fan of automatic unlatching, avoids people when using the gas hot-water apparatus shower, forgets out ventilating fan, and causes carbon monoxide poisoning.
For achieving the above object, solution of the present utility model is: a kind of ventilating fan of automatic unlatching, comprise ventilating fan, and described ventilating fan is provided with gas transducer; The power switch of described ventilating fan is connected by wire with gas transducer.
Aforementioned gas transducer is infrared gas sensor.
After using such scheme, because ventilating fan of the present utility model is equipped with infrared gas sensor, people are when using the gas hot-water apparatus shower, when coal gas burns insufficient in gas hot-water apparatus, when disengaging the gases such as carbon monoxide, infrared gas sensor just can detect the gases such as carbon monoxide, infrared gas sensor just triggers the power switch of ventilating fan and automatically starts, operates, prevent that people are when using the gas hot-water apparatus shower, forget out ventilating fan, cause carbon monoxide poisoning, threat to life; And infrared gas sensor and instrument application are extensive, be applicable to monitoring and be close to various easy gases, have that precision is high, selectivity good, reliability is high, do not poison, do not rely on oxygen, be subjected to the remarkable advantages such as the environmental disturbances factor is less, the life-span is long, and progressively become the market mainstream in future.
Description of drawings
Fig. 1 is the utility model embodiment's schematic diagram.
Embodiment
Provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of ventilating fan of automatic unlatching comprises ventilating fan 1, and ventilating fan is provided with infrared gas sensor 2; The power switch of ventilating fan is connected by wire with infrared gas sensor.
People are when using the gas hot-water apparatus shower, when coal gas burns insufficient in gas hot-water apparatus, when disengaging the gases such as carbon monoxide, infrared gas sensor just can detect the gases such as carbon monoxide, infrared gas sensor just triggers the power switch of ventilating fan and automatically starts, operates, and prevents that people from when using the gas hot-water apparatus shower, forgetting out ventilating fan, cause carbon monoxide poisoning, threat to life; And infrared gas sensor and instrument application are extensive, be applicable to monitoring and be close to various easy gases, have that precision is high, selectivity good, reliability is high, do not poison, do not rely on oxygen, be subjected to the remarkable advantages such as the environmental disturbances factor is less, the life-span is long, and progressively become the market mainstream in future.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
