Abstract
The utility model relates to a household alarm device which comprises a casing and an electric circuit installed in the casing, wherein, a display is installed on the casing, an adjusting key, a functional key and a switching key are installed at the lower part of the casing, and a zipper ring is also arranged on the casing; and the electric circuit is mainly formed by connecting a timing switch, a starting switch, a power circuit, a monolithic processor PIC16C54, a display circuit and a loudspeaker in series. The utility model utilizes one section No.5 battery and is designed with 10 kinds of ring for arbitrary selection, the volume can be adjusted, the interval time of the ring can be adjusted, and the ring also can be set to vibrant state. The household alarm device is compact in shape, can be put in a pocket, and can be held in hand or placed on a table, thereby facilitating the use.
Description
Technical field
The utility model relates to a kind of alarm, specifically a kind of household alarm.
Background technology
In life, hear that through regular meeting the someone says: " so-and-so has burnt out pot when cooking, and is not good enough ...." also have family reserve tank when last water owing to can not in time closing, water overflows Kingsoft; Electric cooker or electromagnetic oven are careless when cooking to overflow to such an extent that completely all be, that is just of common occurrence especially, especially aging old man, young children, the forgetful more prosperous easy such or such mistake of making of young and middle-aged people.
Summary of the invention
The purpose of this utility model provides a kind of household alarm.As long as configure the time, it will send melodious the tinkle of bells, has reminded your this What for incessantly.
The utility model is made up of shell and cased circuit, and display is installed on the shell, the bottom be equipped with regulate strong, function is strong and switch is strong, also is provided with the slide fastener ring on the shell.
Above-mentioned circuit mainly is to be composed in series by time switch, starting switch, power circuit, single-chip microcomputer PIC16C54, display circuit, loudspeaker.Single-chip microcomputer PIC16C54 is a primary controller, its 6 output terminals resistance 201 of contacting respectively, and connect and controlling two 2 displays; Another output terminal resistance 222 of connecting, the triode of ining succession is being controlled loudspeaker; There are diode, resistance 103, electric capacity to play the stabilized power source effect in the power circuit of the input end of primary controller; Time switch and starting switch are in series with the input end that current-limiting resistance 103 inserts primary controller respectively.
Timing range counts down: 1～99 minute; The demonstration early warning powers on: 50 minutes;
LED shows: 51-99～0; Then BZ shows together with a position LED:0.5 second.
The utility model uses No. 5 batteries of 1 joint, and design has 10 kinds of the tinkle of bells can be for selecting voluntarily, the volume scalable, the tinkle of bells length scalable interval time, but also furnishing vibrations.Its shape not quite can be contained in the pocket, can be hand held in, or be placed on the desk, easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model,
Fig. 2 is a side view of the present utility model,
Fig. 3 is a circuit diagram of the present utility model.
Among the figure, 1. regulate and be good for, 2. regulate and be good for, 3. function is strong, and 4. switch is strong, 5. display, 6. shell, 7. slide fastener ring.
Embodiment
In the drawings, the utility model is made up of shell 6 and the circuit that are contained in the shell 6, and display 5 is installed on the shell 6, and the bottom is equipped with regulates strong 1 and 2, function strong 3 and switch is good for 4, also is provided with slide fastener ring 7 on the shell 6.
Above-mentioned circuit mainly is to be composed in series by time switch, starting switch, power circuit, single-chip microcomputer PIC16C54, display circuit, loudspeaker.Single-chip microcomputer PIC16C54 is a primary controller, its 6 output terminals resistance 201 of contacting respectively, and connect and controlling two 2 displays; Another output terminal resistance 222 of connecting, the triode of ining succession is being controlled loudspeaker; There are diode, resistance 103, electric capacity to play the stabilized power source effect in the power circuit of the input end of primary controller; Time switch and starting switch are in series with the input end that current-limiting resistance 103 inserts primary controller respectively.
Timing range counts down: 1～99 minute; The demonstration early warning powers on: 50 minutes;
LED shows: 51-99～0; Then BZ shows together with a position LED:0.5 second.
During use, configure time and the tinkle of bells length interval time, after the time, the continuous sound of the tinkle of bells will have been reminded your this What for.
