Abstract
The utility model provides a toxic gas automatic alarm device suitable for the field of sensing and automatic control. The toxic gas automatic alarm device comprises an air-sensitive probe, an electronic switch and an alarming device, wherein, the air-sensitive probe is used for sensing toxic gas; the electronic switch connected with the air-sensitive probe is used for being switched on when the air-sensitive probe senses the toxic gas in certain concentration; and the alarming device connected with the electronic switch is used for sending a prompt when the electronic switch is switched on. By automatically sensing the toxic gas in air, the toxic gas automatic alarm device can automatically give a sounding and light alarm and synchronously discharge the toxic gas when sensing the toxic gas, so that the danger of toxic gas existence can be well warned early for people, and life safety of people can be guaranteed.
Description
Technical field
The utility model belongs to sensing and automation field, relates in particular to a kind of toxic gas autoalarm.
Background technology
All have every year many life to be seized by toxic gas, have the people in the room because of gas leak death by suffocation; Someone poisons dead at storehouse because of harmful gas; There is coal miner to die tragically in this blast of down-hole invar; Occupy in newly-decorated house, the toxic gas (as formaldehyde) that sends because of finishing material got incurable disease; Or the like.Toxic gas has become main " killer " in numerous accidents because of it is difficult to discover after reaction with people, therefore, the early warning of toxic gas has been become the technology that people pay close attention to and press for.
The utility model content
The purpose of this utility model is: a kind of toxic gas autoalarm is provided, is intended to solve and existing toxic gas is lacked effective early warning make people's life security be subject to the problem of the threat of toxic gas.
The purpose of this utility model is achieved in that
A kind of toxic gas autoalarm, described device comprises:
Gas-sensing probe is used to respond to toxic gas;
With the electronic switch that described gas-sensing probe is connected, be used for when described gas-sensing probe is sensed certain density toxic gas, connecting;
With the warning device that described electronic switch is connected, be used for when described electronic switch is connected, sending prompting.
Described warning device comprises music block and the light-emitting device that is connected with described electronic switch, and the loudspeaker that is connected with described music block, described music block and light-emitting device are distinguished output audio information to described loudspeaker plays and luminous when described electronic switch is connected.
Described device also comprises relay that is connected with described electronic switch and the scavenger fan that is connected with described relay, and described relay drives scavenger fan work when described electronic switch is connected, discharge toxic gas.
Described electronic switch also comprises delay circuit, is used for charging when described electronic switch is connected, and is that described relay power supply is to prolong its working time after described electronic switch disconnects.
Outstanding advantage of the present utility model is: the utility model is by responding to airborne toxic gas automatically, when finding toxic gas, send sound and light alarm automatically, and discharge toxic gas synchronously, thereby can be the existence of this harm of personnel's early warning toxic gas well, ensure people's life security.
Description of drawings
Fig. 1 is the structural drawing of the toxic gas autoalarm that provides of the utility model preferred embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 shows the structural drawing of the toxic gas autoalarm that the utility model preferred embodiment provides, and for convenience of explanation, only shows the part relevant with the utility model.
Described device comprises gas-sensing probe 1, electronic switch 2 and the warning device that connects successively, described gas-sensing probe 1 is as the sensor of toxic gas, after energising, promptly become a variable resistor, one resistance that meets its two ends of poisonous gas will be reduced to several K immediately by tens K, and after the content of toxic gas is reduced to the safety value of regulation, its resistance will rise again at once.
Described warning device can be a light emission alarm device, also can be the sounding alarm device.In the utility model preferred embodiment, described warning device had both comprised sounding alarm device (music block 3 and loudspeaker 5), also comprised light emission alarm device (light-emitting device 6).In addition, also include toxic gas removal system (relay 4 and scavenger fan 7) in the described toxic gas autoalarm.
After described device energising, when not having toxic gas or toxic gas content low in the air, the resistance that gas-sensing probe 1 presents is big, make electronic switch 2 under the voltage effect, be in closed condition, at this moment, music block 3, relay 4 and light-emitting device 6 (light emitting diode, LED etc.) are not all worked; When gas-sensing probe 1 runs into toxic gas, its resistance that presents reduces, make electronic switch 2 connect, music block 3, relay 4 and light-emitting device 6 are all started working, music block 3 output audio information to loudspeaker 5 is play, and cooperates with light-emitting device 6 and sends sound and light alarm, simultaneously, relay 4 drives scavenger fan 7 work, discharges airborne toxic gas.
In the utility model, described electronic switch 2 also comprises the delay circuit of being made up of resistance and electric capacity.When electronic switch 2 closures, after electric capacity in the described delay circuit is full of electricity, electric capacity reaches the purpose of electronic switch 2 delay workings to conductive discharge, delay time is half a minute (length of time-delay can be regulated by the value that changes resistance or electric capacity as required) approximately, can make vent fan 7 delay workings like this, so that the toxic gas in the room has been arranged; When the tele-release of electric capacity was intact, electronic switch 2 just disconnected, and loudspeaker 5, vent fan 7 etc. quits work.And so forth, can guarantee people's life security.
The toxic gas autoalarm that the utility model provides all has the monitoring, alarming effect of comparison sensitivity to toxic gases such as carbon dioxide, oil smoke, coal gas, biogas, chlorine, formaldehyde, sulfuretted hydrogen, sulphuric dioxide, and environment such as can be used for constructing under resident room, storehouse, factory floor, tunnel construction, the coal mine.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
