Abstract

The utility model relates to an alarm for doors and windows, which divides a shell body into a main shell body and an auxiliary shell body, wherein an electronic alarm line which controls whether the alarm works or not by a magnetic-control dry reed tube is arranged inside the main shell body; a magnetic body which attracts the dry reed tube is arranged inside the auxiliary shell body correspondingly. The alarm for doors and windows is characterized in that a YL-323B special double-voice integrated circuit chip is adopted by the electronic alarm line, and an output of the 5OUT end of a foot is connected with an amplifying circuit of a transistor T. An output of the amplifying circuit of the transistor T is connected with a buzzer F by the coupling of a transformer B. The 8Vcc end of the foot is connected with a power supply. The 4GND end of the foot is earthed. The TG1 end and the TG2 end of feet 1 and 2 are connected with a power supply end by an option switch S1. The TG3 end of a foot 3 is earthed by a switch S2, namely, the magnetic-control dry reed tube. A resistor R1 is connected between the OSCO1 end and the OSCO2 end of feet 6 and 7. The alarm for doors and windows has the advantages of simple structure, low cost, double functions of prompt and alarm, etc.

Description

The door and window alarm

Technical field

The utility model relates to a kind of alarm, particularly relates to a kind of door and window alarm.

Background technology

The door and window alarm of Xiao Shouing is the single-tone warning function basically in the market, promptly when moving, door and window controls main alarm by the magnetic control principle, make its warning, its functional limitation does not have the doorbell voice prompt in having only warning function, when installation is gone up to the doorstep, sometimes wish that such alarm can send " ding-dong " sound or other similar sound points out the someone to pass in and out, old-fashioned door and window alarm does not have this function, so need do further improvement.

Summary of the invention

Technical problem to be solved in the utility model is to provide at above-mentioned prior art present situation that a kind of structure is still simple, cost is low, have the prompting and the bifunctional door and window alarm of reporting to the police.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of door and window alarm, it comprises the electronic warning circuit that is fixed on the housing inner chamber, housing is divided into main casing and sub-shell, be equipped with in the main casing by the magnetic control tongue tube and come Control work whether electronic warning circuit, the magnetic of adhesive tongue tube is housed in sub-shell accordingly, it adopts the special-purpose double-tone integrated circuit (IC) chip of YL-323B to it is characterized in that described electronic warning circuit, the output of its pin 5OUT end connects the amplifying circuit of transistor T, the amplifying circuit output of transistor T is through the coupling of transformer B, meet hummer F, pin 8Vcc termination power, pin 4GND holds ground connection,

1,2 TG1 and TG2 end connect power end by selector switch S1, the TG3 end of pin 3 is a magnetic control tongue tube ground connection by switch S 2, pin 6,7 OSCO1, be connected to resistance R 1 between the OSCO2 end.

Useful is, its pin of described integrated circuit (IC) chip 3TG3 end is connected to anti-self-excitation capacitance C3 between over the ground, and playing good antinoise purpose, and circuit is simple and practical.

Useful is that the described main casing and the sub-shell back side are bonded with two-sided blob of viscose, conveniently to install and use.

Compared with prior art, advantage of the present utility model is: only use monolithic integrated optical circuit, just have prompting and report to the police difunctionally, offer the practical new product that client's function is complete, cost is low, circuit is simple, makes easily and produces.

Fig. 2 is the structure partial cut-open view of the utility model embodiment.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Illustrate as Fig. 1-2, this kind door and window alarm, it comprises the electronic warning circuit that is fixed on the housing inner chamber, it is divided into main casing 1 and sub-shell 2 with housing, be equipped with by magnetic control tongue tube 6 to come Control work whether electronic warning circuit in the main casing 1, the magnetic 5 of adhesive tongue tube be housed as permanent magnet 2 li of sub-shells accordingly.And the electronic warning circuit adopts the YL-323B dedicated IC chip, it is by Ealing (Ningbo) Electronics Co., Ltd. produce and market, the pin 5OUT end output of chip connects the amplifying circuit of transistor T, the amplifying circuit output of transistor T is through the coupling of transformer B, meet hummer F, pin 8Vcc termination power, pin 4GND holds ground connection,

1,2 TG1 and TG2 end connect power end by selector switch S1 respectively, the TG3 end of pin 3 is a magnetic control tongue tube ground connection by switch S 2, simultaneously, also be connected to anti-self-excitation capacitance C3, pin 6 between integrated circuit (IC) chip pin 3TG3 holds over the ground, 7 OSCO1, be connected to resistance R 1 between the OSCO2 end.The main casing 1 and sub-shell 2 back sides are bonded with two-sided blob of viscose or have screw hole.Main casing 1 bottom is general battery cavities, accommodates button cell, last grafting upper cover plate 3, and the side of main casing 1 has the hole, and the button 4 of selective switch exposes.

Its principle of work is such, and its electronic circuit comprises that power supply, selector switch S1, magnetic control tongue tube are that switch S 2, special IC and the amplification sound-producing device of reporting to the police are connected to form the loop by the lead connection in series-parallel.Power supply is that 4.5V direct current and capacitor C 1 are formed, and integrated circuit is the special-purpose double-tone integrated circuit of being sold by Ealing (Ningbo) Electronics Co., Ltd. of YL-323B, and the amplification sound-producing device of reporting to the police is made up of capacitor C 2, triode T9014, magnetic transformer B and hummer F.
