Abstract
The utility model relates to an alarm for a door bell and a water level monitor, comprising a water-level-alarm circuit, a doorbell circuit, a collective amplification circuit and an alarm shell.
Description
The utility model relates to a kind of electronic alarm, especially can be to tank water level and the alarm that utilizes doorbell to report to the police.
A kind of water level is arranged at present, Doorbell alarm device, by level sensor, doorbell button switch, a music integrated circuit, amplifying triode and loudspeaker are formed, level sensor is made of two metallic laminas, and be placed in the relevant position of tank, when the water level in the tank contacts with metallic laminas, current in wire is switched on, its signal is through music integrated circuit, amplifying triode to loudspeaker sends sound equipment, to warn the water level in people's tank full, when pressing doorbell button switch AN, its signal is through same music integrated circuit, amplifying triode is to loudspeaker, thereby the shortcoming that exists water level alarm and Doorbell alarm device not to report to the police simultaneously, and is identical because of its sound equipment simultaneously, make us being difficult to distinguish, often cause illusion.
The purpose of this utility model provides a kind of water level, the dual-purpose alarm simultaneously of doorbell, and it can not only be reported to the police to the tank water level, and can report to the police to messenger.
The purpose of this utility model is achieved in that by level sensor SCQ and the music integrated circuit IC that is arranged in the alarm housing
1, anti-tampering capacitor C
1And current-limiting resistance R
1Constitute the water-level alarm circuit, level sensor SCQ is by being arranged at the tongue tube J in the sensor housing and forming with the magnetic patch that float constitutes one, by pushbutton switch AN be arranged at music integrated circuit IC in the alarm housing
2, anti-tampering capacitor C
2And current-limiting resistance R
2Constitute doorbell circuit, constitute shared amplifying circuit by the amplifying triode BG and the loudspeaker Y that are arranged in the alarm housing.Water-level alarm circuit, doorbell circuit and shared amplifying circuit method of attachment are music integrated circuit IC
1Positive pole and IC
2Positive pole be in parallel, and join music integrated circuit IC with the positive pole of battery DC
1Negative pole and IC
2Negative pole be in parallel, and join current-limiting resistance R with the negative pole of battery DC
1An end and music integrated circuit IC
1Output terminal B
1Join, the base stage B of its other end and amplifying triode BG joins, current-limiting resistance R
2An end and music integrated circuit IC
2Output terminal join, the base stage B of its other end and amplifying triode BG joins, in order to distinguish the different of water-level alarm sound equipment and doorbell alarm sound, music integrated circuit IC
1Can select music sound for use, music integrated circuit IC
2Can select " ding-dong " sound equipment for use.
Because adopt such scheme, it can also can be Doorbell alarm device, and can report to the police simultaneously as water level alarm.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is an alarm housing profile structural map of the present utility model.
Fig. 3 is an alarm case side view of the present utility model.
Fig. 4 is sensor arrangement figure of the present utility model.
Fig. 5 is a sensor side view of the present utility model.
Among the figure 1, magnetic patch 2, float 3, level sensor housing 4, case lid 5, alarm housing 6, loudspeaker 7, socket 8, socket
In the embodiment shown in fig. 1, socket CK
1(8) and socket CK
2(7) be arranged at the both sides of alarm housing (5) respectively, in alarm housing (5), socket CK
1(8) a end and the positive pole of battery DC join, its other end and music integrated circuit IC
1Trigger electrode A
1Join music integrated circuit IC
1And IC
2Anodal mutually and connect, and join music integrated circuit IC with the positive pole of battery DC
1And IC
2Negative pole link, and join anti-tampering capacitor C with the negative pole of battery DC
1An end and music integrated circuit IC
1Trigger electrode A
1Join, the negative pole of its other end and battery DC joins, the end of current-limiting resistance R1 and music integrated circuit IC
1Output terminal B
1Join, the base stage B of its other end and amplifying triode BG joins, socket CK
2(7) a end and the positive pole of battery DC join, its other end and music integrated circuit IC
2Trigger electrode A
2Join anti-tampering capacitor C
2An end and music integrated circuit IC
2Trigger electrode A
2Join, the negative pole of its other end and battery DC joins, current-limiting resistance R
2An end and music integrated circuit IC
2Output terminal B
2Join, the base stage B of its other end and amplifying triode BG joins, the negative pole of the emitter E of amplifying triode BG and battery DC joins, the collector C of amplifying triode BG and loudspeaker Y(6) an end join, loudspeaker Y(6) positive pole of the other end and battery DC joins, and in level sensor housing (3), is provided with the magnetic patch (1) that tongue tube J and same float (2) constitute one, level sensor shell (3) is fixed by case lid (4), by plug CT
1Can with the socket CK on the alarm housing (5)
1(8) join, pushbutton switch AN is by plug CT
2Can with the socket CK on the alarm housing (5)
2Join, by level sensor SCQ, music integrated circuit IC
1, anti-tampering capacitor C
1And current-limiting resistance R
1Constitute the water-level alarm circuit, by pushbutton switch AN, music integrated circuit IC
2, anti-tampering capacitor C
2And current-limiting resistance R
2Constitute doorbell circuit, by amplifying triode BG and loudspeaker Y(6) constitute shared amplifying circuit.Its principle of work is: SCQ places tank with level sensor, when the water level in the tank contacts with level sensor SCQ, float (2) drives magnetic patch (1) and together moves upward under the buoyancy of water effect, when magnetic patch (1) and tongue tube J are close, two contact adhesives of tongue tube J and conducting, music integrated circuit IC
1Become triggering state, music integrated circuit IC by non-triggering state
1Output terminal B
1Signal output is just arranged, and this signal is through current-limiting resistance R
1Base to amplifying triode BG is reported B, through the collector C of amplifying signal by amplifying triode BG, promotion loudspeaker Y(6) sends the music sound, if close water swivel this moment, need level sensor SCQ is taken out, magnetic patch (1) just is separated with tongue tube J, opens circuit in two contacts of tongue tube, and the music signal that is taken place stops automatically.The doorbell warning circuit is except that the structure of pushbutton switch AN and level sensor SCQ is inequality, and other structures are identical with water level alarm, and its principle of work is as the same, for the sound equipment of difference water level alarm and Doorbell alarm device different, music integrated circuit IC
