Abstract
The utility model discloses a safety range hood smoke exhauster, which comprises a range hood, a relay, a gas detection sensor, a signal processing circuit and an alarm circuit. The gas detection sensor is arranged outside the casing of the range hood. When the gas detection sensor detects that the indoor gas concentration reaches the alarming concentration, the gas detection sensor can send alarm signals, and the range hood can be automatically activated to exhaust. The utility model prevents serious fire and explosion caused by the gas, and has the advantages of reliable performance, low cost, easy promotion and application, simple operation and the like.
Description
Technical field:
The utility model relates to a kind of smoke exhaust, specifically is exactly safe range hood.
Background technology:
At present, the smoke exhaust that market occurs only has simple function, promptly can only get rid of the function of oil smoke.Along with the improvement of living condition, no matter be city or rural area, it all is very general using liquefied gas cooker, and liquefied gas cooker inconvenience is used, and also having impelled smoke exhaust to use increases.And the simple function of smoke exhaust be difficult to satisfy the demands with people, and therefore, people are indispensable again prevents some instruments such as gas leak detector of gas leakage.So guarantee the safety and the health of family, smoke exhaust and gas leak detector all will be installed by each family, cause very big waste and inconvenience.Therefore, develop a kind of multi-functional smoke exhaust, very necessary.
The utility model content:
The utility model purpose provides a kind of safe range hood with gas alarm system.
To achieve these goals, the technical solution of the utility model is as follows:
Safe range hood comprises smoke exhaust, relay, coal gas acquisition sensor, signal processing circuit and warning circuit.Described coal gas acquisition sensor is provided with outside the casing of smoke exhaust, the convenient concentration of surveying coal gas; Described warning circuit is provided with buzzer, and this buzzer and relay are connected in parallel, and an end of described relay is connected on the warning circuit, and the other end connects on the switch of smoke exhaust; Circuit connects between described relay, coal gas acquisition sensor, signal processing circuit and the warning circuit, and is arranged in the casing of smoke exhaust.
Operation principle of the present utility model is as follows:
When the coal gas acquisition sensor detected that concentration reaches warning concentration in the room, the coal gas acquisition sensor conveyed to signal processing circuit with perception, drove warning circuit, buzzer sounds, the relay of Lian Jieing causes switch opens simultaneously, and smoke exhaust starts, and discharges coal gas within doors.
The beneficial effects of the utility model are, because the employing gas alarm device has been avoided the generation because of coal gas blast malignant event on fire, and the performance height, with low cost, and can discharge coal gas within doors automatically, safer, health is convenient to promote the use of with easy to implement.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the module diagram of the utility model safety range hood.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, safe range hood comprises smoke exhaust 1, relay 4, coal gas acquisition sensor 2, signal processing circuit 3 and warning circuit 5.Coal gas acquisition sensor 2 is provided with outside the casing of smoke exhaust 1, the convenient concentration of surveying coal gas; Buzzer 6 on relay 4 and the warning circuit 5 is connected in parallel, one end of this relay 4 is connected on the warning circuit, the other end connects on the switch 7 of smoke exhaust, control the open and close state of smoke exhaust 1, circuit connects between relay 4, coal gas acquisition sensor 2, signal processing circuit 5 and the warning circuit 5, and is arranged in the casing of smoke exhaust 1.
During use, the switch 7 of normally opening smoke exhaust can use; When under night or unmanned situation, coal gas is revealed, coal gas acquisition sensor on the casing of smoke exhaust 1 surveys 2 when gas concentration reaches warning concentration, coal gas acquisition sensor 2 conveys to signal processing circuit 3 with perception, signal processor 3 conveys to warning circuit 5, warning circuit 5 is given buzzer 6 by electric current, relay 4 also passes electric current is arranged simultaneously, cause suction shaft 7 closures, thereby smoke exhaust 1 starts, discharge coal gas within doors, therefore effectively prevented the generation of or blast serious accident on fire because of coal gas.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
