Description

Household electronic anti-theft alarm

The utility model relates to a kind of family expenses burglar alarm.

Present known domestic electronic burglar alarm (burglar alarm that provides as patented claim such as No. 89210047.8, No. 89220027.8, No. 88217499.1), its structure is all comparatively complicated, cost is also higher, the alert switch of pin especially is not set, thereby make its alarm alert signal of when kinsfolk or the article owner touch article, also by mistake transmitting messages, to living environment bring needn't dried scratching.

The purpose of this utility model is to provide a kind of circuit simple and be provided with the domestic electronic burglar alarm of the alert switch lock of pin, so that by opening the alert lock of pin, guarantees the alert signal of by mistake not transmitting messages when kinsfolk or the article owner touch article.

The utility model can be realized by following measure, with the audible alarm circuit ic chip ₁The normal opened contact K of power input series relay J ₁After connect battery, its output termination loudspeaker B is with the music mimic channel ic chip of being set up that triggers function that has ₂Output termination audible alarm circuit ic chip ₁Input end, its power input and relay J and K switch ₂Connect battery after the connection; Triggering spring ［ 1 ］ the one termination ic chip of being set up ₂(2) pin, its other end is unsettled, so that can touch ic chip after being shaken ₂Trigger end (3) pin; In K switch ₂An alert lock of pin is established on the side, makes the lock pin behind its locking can touch K just ₂Closed.

Except that the alert switch lock of the employing pin described in the technique scheme, also in K switch ₁Two ends also meet a button switch K ₃, this makes the utility model not only can be used for the household goods burglar alarm, also can be contained in to be used as antitheft, alarm bell sound-producing device on the vehicles such as bicycle, motorcycle, has the function of one-object-many-purposes.

Fig. 1 is the utility model circuit theory diagrams;

Fig. 2 is that the utility model global facility is in conjunction with synoptic diagram.

The utility model is described in further detail below in conjunction with accompanying drawing:

The utility model is by the audible alarm ic chip ₁With music simulation ic chip ₂, battery E, trigger the alert K switch of spring ［ 1 ］, the alert lock of pin ［ 2 ］, relay J and pin ₂Form, they all are installed in the circular box that a hard moulding material makes, the audible alarm ic chip ₁The normal opened contact K of (1) pin series relay J of power input ₁After respectively and (2) pin connect battery E two ends, its output terminal (3) pin and (4) pin meet loudspeaker B; Music simulation ic chip ₂(4) pin of output terminal and (1) pin connect the audible alarm ic chip ₁Input end (5) pin and (2) pin; Its power input (1) pin connects battery cathode, relay J of (2) pin series connection and K switch ₂After connect anode; Trigger spring ［ 1 ］ one termination ic chip ₂(2) pin, the other end is unsettled, can touch ic chip after it is shaken ₂Trigger end (3) pin; In K switch ₂An alert lock of pin ［ 2 ］ is equipped with on the side, and the lock pin behind its locking ［ 3 ］ touches K just ₂Closed.

Claims

1, a kind of burglar alarm includes the audible alarm circuit ic chip ₁, relay J, battery E and loudspeaker B, it is characterized in that the music mimic channel ic chip of newly establishing that triggers function that has ₂Output termination audible alarm circuit ic chip ₁Input end, its power input and relay J and K switch ₂Meet battery E after the connection; Triggering spring [1] the one termination ic chip of being set up ₂(2) pin, its other end is unsettled, so that can touch ic chip after being shaken ₂Trigger end (3) pin; In K switch ₂An alert lock of pin [2] is established on the side, and the lock pin behind its locking [3] touches K just ₂Closed.

2,, it is characterized in that at the two ends, adhesive contact of relay J and connect a button switch K according to the described burglar alarm of claim ₃
