Description

Anti-false tripping circuit of multi-smoke alarm

Technical Field

The utility model relates to a smoke alarm technical field especially relates to a many smoke alarm prevents maloperation return circuit.

Background

The smoke alarm is more and more popular in industrial and agricultural life, a smoke alarm is arranged in a smoke alarm loop, but the circuit has a problem that in places where smoke is easy to appear under special working conditions such as chemical plants, steam rooms, rural areas, city effect places and the like, under the condition of non-fire, the smoke alarm is also easy to mistakenly trip due to sensing smoke caused by the non-fire, so that the electric equipment is often forced to stop working, and great troubles are brought to production and operating personnel.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, an object of the present invention is to provide a multiple smoke alarm false tripping prevention loop with low false alarm rate.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a many smoke alarm prevents maloperation return circuit, the return circuit includes smoke alarm, smoke alarm includes smoke alarm body and automatic closed smoke alarm switch when smoke alarm body senses smog, its characterized in that:

the smoke alarm is provided with a plurality of groups of smoke alarm bodies which are connected in parallel between the live wire and the zero wire, and a plurality of groups of smoke alarm switches are connected in series to form a smoke alarm switch component;

the circuit further comprises a switch member connected to the smoke alarm switch assembly and acting to de-energise the back end load when the smoke alarm switch assembly is fully closed;

and a branch formed by the smoke alarm switch component and the switch component is connected with the smoke alarm body in parallel.

Furthermore, the circuit also comprises a manual brake-separating switch which is connected in parallel at two ends of the smoke alarm switch component and is used for manually closing to enable the switch component to act.

Further, the switching component includes a circuit breaker.

Furthermore, the circuit also comprises a fuse connected in series between the live wire and a parallel point, and the parallel point is formed by connecting a smoke alarm switch component and a manual brake-separating switch in parallel and is close to the live wire side.

Further, the smoke alarm has 2 groups.

Further, the smoke alarm is an infrared photoelectric sensor.

Further, the alarm sound of the smoke alarm is not lower than 60 dB.

Further, the alarm current of the smoke alarm is not less than 10 mA.

Further, the smoke alarm is BRJ-301ALD in model number.

Furthermore, the model of the manual brake-separating switch is LAY 50-22D-11J/R.

Compared with the prior art, the utility model has the advantages of:

by arranging a plurality of groups of smoke alarms and connecting smoke alarm switches in series in the circuit, the alarm action can be performed only when the smoke alarm switch assembly is completely closed, the false alarm problem of a single smoke alarm is effectively avoided, and the alarm accuracy is improved.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Fig. 1 is a schematic structural diagram of a preferred embodiment of the present invention, and as shown in the drawing, the anti-false-tripping circuit of the multiple smoke alarm includes a smoke alarm YG, which includes a smoke alarm body YGB and is automatically closed when the smoke alarm body YGB senses smokeThe combined switch YGK of the smoke alarm is used for ensuring the alarm accuracy and preventing the false alarm of a single smoke alarm when only one single smoke alarm is in the circuit, and the YG of the smoke alarm has a plurality of groups, thereby forming a plurality of groups of YGB of the smoke alarm body_iMultiple groups of smoke alarm switches YGK connected in parallel between live wire and zero wire_iThe YGK switch modules are connected in series to form the layout of the smoke alarm switch module; the circuit also comprises a switch component GF which is connected with the switch component YGK of the smoke alarm and acts when the switch component YGK of the smoke alarm is completely closed so as to cut off the power of the load at the rear end, and a branch formed by the switch component YGK and the switch component GF is connected with the smoke alarm body in parallel. In this embodiment, the smoke alarm has 2 groups.

In order to ensure that the circuit is also powered off when the smoke alarm fails, and to prevent danger, the circuit further includes a manual break switch SBS connected in parallel to both ends of the switch assembly YGK of the smoke alarm for manually closing the switch assembly to actuate the switch member.

The switch part GF comprises a breaker F, and because the breaker F can not be electrified for a long time, the switch part GF also comprises a switch S connected with the breaker F so as to break the breaker at intervals and not cause an alarm to give an alarm. Meanwhile, the circuit also comprises a fuse FU connected in series between the live wire and a parallel point, and the parallel point is formed by connecting the smoke alarm switch assembly YGK and the manual switch-off switch SBS in parallel and is close to the live wire side.

In the application, the smoke alarm is an infrared photoelectric sensor, the model is BRJ-301ALD, the alarm sound is not lower than 60dB, the alarm current is not less than 10mA, and correspondingly, the manual brake-separating switch is LAY 50-22D-11J/R.

While embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
