Abstract
The utility model relates to a timer for combustion gas, which can control the burning time of the inflammable gas in the timing way. The utility model is composed of a stabilized voltage supply, a start button, a timing selection button, a timing circuit, an inflammable gas sensor, an alarm circuit, an alarm speaker, a logic circuit, a switching circuit, and an electromagnetic valve. The timing time is selected, the start button is pressed, and the timing circuit is under the timing state, the logic circuit is triggered, and the on-off of the electromagnetic valve is controlled by the switching circuit, and the automatic control for the burning time of the inflammable gas can be realized. When the inflammable gas leakage phenomenon occurs, the alarm system can send out the alarm in time, the gas source is cut off, and the fire is extinguished. The utility model is suitable for the technical field of cooking and preheating for the metal workpiece.
Description
The utility model relates to a kind of electronic timer, specifically timing controlled coal gas, rock gas, liquid gas, biogas period of combustion, is applicable to cooking, gives metal workpiece preheating field.
Existing in cooking, pine for for metal workpiece in advance, be to adopt hand switch control the period of combustion of inflammable gas, this method igniting back user of service can not away from, the low precision in control time, if user of service's carelessness, influence the preheating temperature of cooking quality or metal workpiece, when inflammable gas leaks, can not in time turn-off source of the gas and report to the police, have an accident or cause fire because of forgetting to close gas sometimes.
In order to overcome above-mentioned shortcoming, task of the present utility model provides a kind of inflammable gas timer, and purpose is to control automatically the period of combustion of inflammable gas, and promptly regularly the back is closed gas automatically, source of the gas and warning are in time turn-offed in burn-out when inflammable gas leaks.
A kind of inflammable gas timer, by stabilized power supply (14), start knob (9), regularly select to turn round (8), time circuit (15), combustible gas sensor (10), warning circuit (19), alarm speaker (11), logical circuit (16), switching circuit (17), solenoid valve (18) connects to form, it is characterized in that: start knob (9), regularly selecting to turn round (8) uses lead to be connected with time circuit (15) respectively, combustible gas sensor (10), alarm speaker (11) uses lead to be connected with warning circuit (19) respectively, time circuit (15), warning circuit (19) connects logical circuit (16) respectively and constitutes the loop with switching circuit (17), and 220V Ac (1) connects the break-make of control electromagnetic valve (18) by switching circuit (17).
Fig. 1, the inflammable gas timer uses schematic representation.
Fig. 2, inflammable gas timer circuit skeleton diagram.
Fig. 3, inflammable gas timer circuit figure.
Below in conjunction with the explanation of accompanying drawing detail.
Fig. 1 is a kind of use schematic diagram of the present utility model, the air inlet (4) of timing means for combustion gas arrangement (6), gas outlet (5) are connected with wireway (3) with burner (7) with imflammable gas source of the gas (2) respectively, attaching plug in the timing means for combustion gas arrangement (6) inserts in the 220V AC power (1), connect to end completely, can use.
Fig. 2 is the circuit block diagram of inflammable gas timer, 220V Ac (1) is through transformation, rectification, filtering, formed stabilized power supply (14) after the voltage stabilizing, the power supply of each several part circuit is provided, select timing through regularly selecting to turn round (8), enter regularly stable state by starting knob (9) triggering time circuit (15), time circuit (15) makes logical circuit (16) control switch circuit (17) open solenoid valve (18), inflammable gas enters burner (7) by solenoid valve (18), can light use, when being burned to timing, time circuit (15) returns to normal, and makes logical circuit (16), switching circuit (17) all returns to normal, solenoid valve (18) cuts out, cut off the source of the gas of burner (7), burning stops, and this has just realized that combustion gas regularly.When timing system is worked, there is inflammable gas to leak, when concentration reaches alarm point in the air around, combustible gas sensor (10) control warning circuit (19) work, alarm speaker (11) is reported to the police, make logical circuit (16) control switch circuit (17) close solenoid valve (18) simultaneously, cut off the source of the gas of burner (7), burn-out.When fault is got rid of, inflammable gas is when the concentration of air is lower than alarm point around, and system can reuse.
Compared with prior art, the following pluses and minuses of the utility model tool:
1, accurately control the period of combustion of inflammable gas, timing is adjustable, can improve cooking quality in cooking, can accurately grasp the temperature of the workpiece of being heated in the workpiece preheating.
2, save the source of the gas of inflammable gas.
3, avoid forgetting to close accident and the fire that gas causes because of the user of service.
4, when inflammable gas leaks, in time report to the police and turn-off source of the gas, flame-out.
5, convenient, simple to operate by dress, function is many, the user of service can be away from the burner that burns.
6, after shortcoming was the 220V AC outage, the utility model can not use.
