Description

Multifunction alarm device

The utility model relates to a kind of alarm.

In the prior art, the electronic alarm device kind is more, but only plays the warning effect, and for example the induction type alarm when owner leaves home to go out, can hang over alarm on the door lock.But when not needing to report to the police, whole alarm is in closed condition, does not have other purposes again.So its function singleness, purposes are wideless.Independent torch only plays a role in lighting.

The purpose of this utility model is to provide a kind of multifunction alarm device that torch uses that can be used as.

The technical solution of the utility model is: it comprises induction module MD, base stage meet the switch triode BG1 of MD output terminal, the language module KD, the base stage that trigger termination BG1 emitter connects the KD output terminal power amplification triode BG2, is connected on the loudspeaker Y on the BG2 collector; The two ends of power supply E are connected to small electric bulb D2 by K switch 2, and the two ends of power supply E are connected to quartz burner D3 by K switch 3.

The utility model compared with prior art has following advantage:

(1). the utility model can be used as torch, alarm uses, and quartz burner also can be used for anti-counterfeiting detection in addition, is specially adapted to family and uses.

(2). when the utility model uses as alarm, this device can be hung within doors on the door lock, when contacting door lock outdoors, can send audible alarm as the people; It is easy for installation, and practicality is good.

. the utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing is circuit theory diagrams of the present utility model;

Embodiment: the utility model mainly comprises the quartz burner D3 that power supply E, shell, the small electric bulb D2 that plays a role in lighting and anti-counterfeiting detection are used, and it also comprises an induction module MD (model is MD36) and language chip KD (model is KD9562) in addition.Induction module MD, inductance L, capacitor C 1 and induction antenna T1 form the induction of signal circuit jointly.MD induction module 1 pin is the input signal end, and 2 pin are positive source, and 3 pin are output terminal, 4 pin ground connection.During operate as normal, because of MD output terminal 3 is a high level, the BG1 conducting, BG1 launches very high level, and KD is not triggered so do not work, and BG2 does not work yet, and loudspeaker are sounding not.Integrated package KD can dial at any one grade of 5 ends (doorbell sound), 6 ends (chimes of doom) by the preset position of K1.BG2 delivers to loudspeaker Y after KD is amplified by BG2 via the warning of 8 pin output or doorbell output signal.7 pin of KD are power end.When human body during near antenna T1,3 pin of MD are low level, and BG1 ends, and KD obtains the low level trigger pip, sends doorbell or alarm sound by loudspeaker Y after BG2 amplifies.When K2 places 9 positions, lighting circuit work; When K2 places 11 positions, alarm or doorbell work.When K2 places 10 positions, the K3 that closes, triode BG3 work produces high pressure by step-up transformer B at ultraviolet tube D3 two ends, to light ultraviolet lamp tube, be used to detect currency and invoice etc.Described power supply E is a rechargable power supplies, and the two ends of power supply E are connected to rectification circuit, and the prime of rectification circuit is a reduction voltage circuit, and the two ends of reduction voltage circuit are connected to plug.When K2 places 10 simultaneously charging plug to be inserted 220 volts of supply sockets of interchange, charge by the rectification circuit of R3, C4 reduction voltage circuit and D5～D8 composition and 4 couples of power supply E of light emitting diode D4, resistance R of indication usefulness, so battery is a rechargeable battery.

Claims (2)

1. multifunction alarm device comprises induction module MD, base stage meet the switch triode BG1 of MD output terminal, the language module KD, the base stage that trigger termination BG1 emitter connects the KD output terminal power amplification triode BG2, is connected on the loudspeaker Y on the BG2 collector; It is characterized in that: the two ends of power supply E are connected to small electric bulb D2 by K switch 2, and the two ends of power supply E are connected to quartz burner D3 by K switch 3.

2. multifunction alarm device according to claim 1 is characterized in that: described power supply E is a rechargable power supplies, and the two ends of power supply E are connected to rectification circuit, and the prime of rectification circuit is a reduction voltage circuit, and the two ends of reduction voltage circuit are connected to plug.
