Abstract
The utility model discloses a smoke detecting device with both a gas-sensitive type smoke sensing element and an ionic type smoke sensing element, and belongs to the field of fire smoke alarm. The smoke detecting device includes the gas-sensitive type smoke sensing element, the ionic type smoke sensing element, a control circuit board and an alarm indicator. The gas-sensitive type smoke sensing element and the ionic type smoke sensing element are respectively connected with the control circuit board, the control circuit board is connected with the alarm indicator via a signal line, and the alarm indicator gives an alarm in case of detection of fire smoke. Two smoke sensing elements detect smoke independently. When both of the smoke sensing elements detect danger, the control circuit board controls the alarm indicator to give an alarm. The smoke detecting device is simple in structure, has the advantages of good anti-gas and anti-dust interference performance, high reliability and stability, and good waterproof performance, can prevent misinformation in work process, and is simple and elegant in appearance, and easy for installation and maintenance.
Description
Technical field
The utility model belongs to fire hazard aerosol fog warning field, relates to a kind of mist detecting device that has gas-sensitive type and ion-type cigarette sensing unit simultaneously.
Background technology
Smoke alarm claims the fire hazard aerosol fog alarm again, and along with the enhancing of people to fire safety evaluating consciousness, it is more and more important that smoke alarm also seems.Smoke alarm is of a great variety at present, and quality is also uneven, occurring false alarm in some cases or failing to report faults such as alert, causes potential safety hazard easily.
The fire safety of coal mine environment is even more important, so smoke alarm needs stable reliability more as the visual plant of coal field fire safety.But because generally all there are materials such as gas, dust, steam in circumstance complication under the coal mine, multiple gases and solid matter mix the complicacy that has caused the coal field smoke monitoring.
Existing fire hazard aerosol fog alarm generally adopts the single detection principle of photo-electric, air-sensitive formula or ionic formula cigarette sensing unit in the coal mine.Adopt the smoke alarm of ion-type, photo-electric principle to be subject to the interference of coal dust and to produce false alarm; Adopt the smoke alarm of air-sensitive formula principle to be vulnerable to the interference of coal mine gas gas and to produce false alarm;
In view of this, in the safety in production process of coal field, be badly in need of a kind of smoke alarm unit with high reliability and stability at present.
The utility model content
The purpose of this utility model is to provide a kind of mist detecting device that has gas-sensitive type and ion-type cigarette sensing unit simultaneously, and this mist detecting device is simple in structure, is not vulnerable to the interference of complex environment in the mine, has high stability and reliability.
For achieving the above object, the utility model provides following technical scheme:
A kind of mist detecting device that has gas-sensitive type and ion-type cigarette sensing unit simultaneously comprises an air-sensitive cigarette sensing unit, an Ion Smoke Sensor element, a control circuit board and a warning indicator; Air-sensitive cigarette sensing unit for detection of smog links to each other with control circuit board respectively with the Ion Smoke Sensor element, and control circuit board links to each other with warning indicator by signal wire, and the control warning indicator is reported to the police when detecting fire hazard aerosol fog.
Further, described warning indicator adopts audible-visual annunciator.
Further, described air-sensitive cigarette sensing unit is MQ-2 type cigarette sensing unit.
Further, described Ion Smoke Sensor element is NIS-09C type Ion Smoke Sensor element.
The beneficial effects of the utility model are: the mist detecting device that has gas-sensitive type and ion-type cigarette sensing unit simultaneously described in the utility model is simple in structure, with low cost, advantage such as have anti-gas, the dust jamming performance is good, reliability and stability are high, water resistance is good, can avoid producing wrong report in the course of the work, simultaneously outward appearance simplicity generosity, convenient for installation and maintenance.
Description of drawings
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:
Fig. 1 is the sectional view of the utility model mist detecting device;
Fig. 2 is the device workflow diagram.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Mist detecting device of the present utility model improves on the basis of original coal field mist detecting device, as shown in Figure 1, Fig. 1 is the sectional view of the utility model mist detecting device, this mist detecting device comprises the air-sensitive cigarette sensing unit 2 and the Ion Smoke Sensor element 4 that are used for surveying smog, air-sensitive cigarette sensing unit 2 links to each other with control circuit board 1 respectively with Ion Smoke Sensor element 4, and control circuit board 1 also links to each other with warning indicator 3 by signal wire.
Fig. 2 is workflow diagram of the present utility model, the concrete workflow of this mist detecting device is: when device is opened, air-sensitive cigarette sensing unit 2 and Ion Smoke Sensor element 4 are worked simultaneously, independently the smog gas in the coal mine is surveyed respectively, when air-sensitive cigarette sensing unit 2 and Ion Smoke Sensor element 4 all detect danger simultaneously, control circuit board 1 is just controlled warning indicator 3 and is reported to the police, otherwise, if have only a cigarette sensing unit to detect danger, can not start warning this moment, so just avoided in this complex environment of coal field, caused false alarm because the mistake of cigarette sensing unit is surveyed, improved the reliability and stability of pick-up unit.
As a kind of improvement of present embodiment, warning indicator 3 can adopt a kind of audible-visual annunciator, so both can have the light warning function, can carry out dangerous tip at sound again.
Explanation is at last, above preferred embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is described in detail by above preferred embodiment, but those skilled in the art are to be understood that, can make various changes to it in the form and details, and not depart from claims of the present invention institute restricted portion.
