Abstract
The utility model discloses a device for prompting a passenger to passively put out a cigarette. By the device, the passenger is automatically prompted to stop smoking in a voice mode when smoking in a vehicle, so that driving safety is ensured. The device has a simple structure and is convenient to use. The device comprises a gas sensitive sensor module which is connected with a voice prompt circuit for prompting the passenger to stop smoking in the vehicle, wherein the voice prompt circuit is connected with a speaker.
Description
Technical field
The utility model relates to a kind of warning device, relates in particular to a kind of for the car room flue gas inspection prompting occupant device that no smoking.
Technical background
Smoking causes air pollution in the automobile cab that seals or space, compartment, cause that oxygen is not enough in the car, the power that warns is disperseed, elongated, eyesight variation of movement response time, smog can also form deposition on the inside surface of glass for vehicle window, reduce the glass transparent degree, increase is sent a car by the opposite and is caused dizzy danger, has a strong impact on the driver safety driving.Therefore, the device of flue gas inspection is set in vehicle chamber, reminding the occupant not want smoking is very necessary.Open day be that the patent documentation that Dec 15, publication number in 2010 are CN201673576U discloses a kind of relevant battery of electric vehicle smog alarm and emergency cut-off, comprise Smoke Detection sensor, temperature detection sensor, alarm unit, excessive current detection unit and electric-controlled switch etc., can effectively monitor the battery of electric vehicle system.Because the purpose that arranges of this device determines that its smoke transducer is installed and can not be detected flue gas in the vehicle chamber, and whole apparatus structure is complicated, does not also possess sound prompt function.
Summary of the invention
The utility model fundamental purpose is to provide a kind of occupant passive smoke extinguishing apparatus, and when it had people's smoking in car, no smoking for the automatic speech prompting occupant, and to guarantee traffic safety, it is simple in structure easy to use.
The utility model is mainly solved by following technical proposals for the prior art problem, the passive smoke extinguishing apparatus of a kind of occupant, and a gas sensor module connects and comprises the voice warning circuit that no smoking in the car, and voice warning circuit connects loudspeaker.The gas sensor module detects the harmful gases such as CO in Air of car room.When people's smoking was arranged in the car, after the harmful gas concentrations such as CO in Air were increased to and set threshold values, the work of gas sensor module controls voice warning circuit was sent the suggestion voice that no smoking automatically by loudspeaker, and the prompting occupant puts that cigarette out.
As preferably, voice warning circuit is to have the one-off programming speech chip that boombox directly pushes away circuit.The disposable filling of suggestion voice write have PWM output, loudspeaker directly pushes away in the voice integrated chip of circuit, to simplify circuit structure, to reduce installation cost.
As preferably, the gas sensor module comprises gas sensor, amplifying circuit, relay, and the normal opened contact of relay is serially connected in the electric power loop of voice cue module.The weak signal of gas sensor drives the actuating of relay after amplifying circuit amplifies, control voice warning circuit with the normal opened contact of relay and open or close.
As preferably, gas sensor is semiconductor gas sensor.The characteristics such as that semiconductor gas sensor has is highly sensitive, the response fast, good stability, use are simple.
As preferably, to install and also be provided with selector switch and insurance resistance, selector switch, insurance resistance string are connected in the electric power loop of device.Remind in the situation that no smoking not needing, selector switch is set to off-state; When playing the circuit overcurrent, insurance resistance cuts off the electricity supply, ensures the effect of Electrical Safety.
The beneficial effect that the utility model brings is, when people's smoking was arranged in car, no smoking for the voice suggestion occupant, and to guarantee traffic safety, its apparatus structure is simple, functional reliability is high, easy to use.
Description of drawings
Fig. 1 is a kind of schematic block circuit diagram of the present utility model.
Among the figure: the 1st, gas sensor module, the 2nd, voice warning circuit, the 3rd, loudspeaker, the 4th, selector switch, the 5th, insurance resistance, the 6th, gas sensor, the 7th, relay, the 8th, threshold values adjusting resistance, the 9th, transistor.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as shown in Figure 1, the utility model is the passive smoke extinguishing apparatus of a kind of occupant, and the normal opened contact of gas sensor module 1 repeat circuit 7 is serially connected in the electric power loop of voice warning circuit 2, and the loudspeaker output terminal of voice warning circuit 2 connects loudspeaker 3.
Wherein, amplifying circuit, relay 7 that gas sensor module 1 comprises gas sensor 6, is made of threshold values adjusting resistance 8 transistors 9 etc., gas sensor 6 is carbon monoxide semiconductor gas sensors, set the carbonomonoxide concentration threshold values by the resistance of adjusting threshold values adjusting resistance 8, the normal opened contact of relay 7 is closed when surpassing this setting value; Voice warning circuit 2 is to have disposable burning (OTP) speech chip that loudspeaker directly pushes away circuit, and burning has the voice such as " no smoking in the car ", " woulding you please stop smoking "; Selector switch 4 and insurance resistance 5 are serially connected in the power supply input circuit.
When people's smoking is arranged in the car, the CO in Air concentration that causes gas sensor 6 to detect surpasses sets threshold values, transistor 9 conductings, the normal opened contact of relay 7 is closed, the working power of voice warning circuit 2 is switched on, promote loudspeaker 3 and send the suggestion voices such as " no smoking in the car ", " woulding you please stop smoking ", make the occupant extinguish cigarette; Carbonomonoxide concentration drops to threshold values and stops voice suggestion when following; In the situation that does not need to point out, selector switch 4 is set to off-state.
So the utlity model has following characteristics: when people's smoking was arranged in car, the voice suggestion occupant stopped smoking, to guarantee traffic safety, closed voice suggestion in the situation that need not to point out, and apparatus structure is simple, functional reliability is high, very easy to use.
