Abstract
The utility model discloses a closing reminding device of a natural gas valve. The reminding device is provided with an alarming device and a thermistor, wherein the alarming device and the thermistor are connected in series in a circuit. When a gas stove is used, the temperature is raised and the resistance value of the thermistor is raised; when current does not reach the level needed by the working of the alarming device, the alarming device cannot work; after the gas stove is closed, the temperature is reduced and the resistance value of the thermistor is reduced; and when the current reaches the level needed by the working of the alarming device, the alarming device produces sounds, so as to achieve the aim of reminding people of closing a switch of the natural gas valve.
Description
Technical field
The utility model relates to a kind of alarm set, refers to a kind of alarm set that is used to remind the rock gas valve closing particularly.
Background technique
In the daily life, natural gas range every household is all using, and people but often forget the valve of closing rock gas, and cause potential safety hazard, in case careless mistake, even the meeting breaking out of fire, its consequence is hardly imaginable.Do not find as yet that at present a kind of simple effective method addresses this problem.
The model utility content
The purpose of the utility model be to supply a kind of simple in structure, rock gas valve closing alarm set easily and effectively.
For realizing above-mentioned purpose; The rock gas valve closing alarm set that the utility model is conceived includes the emergency alarm that is arranged on gas cooker valve place; Be arranged on the thermistor at gas cooker fire exit place, also be provided with thermistor, emergency alarm and be series at the alarm contact in the circuit.
Further, described alarm contact also is the rock gas valve switch.
The working principle of the utility model is: the thermistor in the rock gas valve closing alarm set of being conceived; Near the gas cooker fire exit, temperature raise when gas cooker used, and the resistance of thermistor increases thereupon; Electric current is less, makes the electric current in the emergency alarm circuit can't start emergency alarm; Temperature reduces after gas cooker is closed, and the resistance of thermistor also decreases, and emergency alarm starts running, and reminds people is closed the rock gas valve.After the rock gas valve switch was closed, then the emergency alarm circuit is also controlled opened circuit, and emergency alarm just stops to give the alarm.
The advantage of the utility model is:
1, the rock gas valve closing alarm set of being conceived has only adopted emergency alarm, alarm contact and thermistor, and is simple in structure, easy to use.
2, because alarm contact and the shared switch of rock gas valve switch after the emergency alarm running, continue sounding, only close the rock gas valve switch, just can close emergency alarm.So just avoided only closing emergency alarm and forgetting the phenomenon of closing the rock gas valve switch.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail.
As shown in Figure 1, the rock gas valve closing alarm set that the utility model is conceived comprises an emergency alarm 1, and said emergency alarm 1 is a toy trumpet, is arranged on gas cooker valve place; Said emergency alarm also is provided with an alarm contact 4, and said alarm contact 4 also is the switch of rock gas valve; 3 fire exit places are provided with two thermistors 2 at gas cooker, and thermistor 2, emergency alarm 1 are series in the circuit with alarm contact 4.
In actual life, when using gas cooker 3, the temperature around the gas cooker 3 raises, and the resistance of thermistor 2 is higher, and the electric current of emergency alarm 1 can not pneumatic work; After gas cooker 3 is closed, the environment temperature step-down, the resistance of thermistor 2 descends thereupon, and electric current increases thereupon, emergency alarm 1 beginning sounding, thus reminds people is closed the rock gas valve switch.
Because emergency alarm 1 and the shared switch of rock gas valve, only close alarm contact 4 after, just can make emergency alarm 1 stop sounding, so just avoided closing emergency alarm and forgetting the phenomenon of closing the rock gas valve switch.
The above embodiment has only expressed a kind of mode of execution of the utility model, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
Claims (3)
