Description

A doorbell alarm

Technical field:

The utility model relates to an alarm device, in particular to a doorbell alarm.

Background technique:

The doorbells sold on the existing market have good practicability and have been well used in urban and rural families; In case of an emergency at home, the doorbell alarm is a trend that is about to develop in society. It can be used as a doorbell and has the effect of anti-theft alarm, which is enough to be loved by consumers. But the alarm and the doorbell of the existing doorbell alarm can not be used simultaneously, only when the owner is in, when the alarm is set to "alarm", the alarm device can start, if it does not start, then it cannot play the role of alarm, and it is inconvenient to use.

Utility model content:

The purpose of the utility model is to provide a doorbell alarm, which can realize the simultaneous use of the doorbell and the alarm, complement each other, and effectively play the role of anti-theft alarm.

In order to achieve the above object, the technical scheme of the utility model is as follows:

A doorbell alarm mainly consists of a box body, a controller, an audio circuit, a buzzer, a doorbell button switch, an indicator light and an alarm circuit; The circuit connection between the light and the alarm circuit, the doorbell button switch controls the start of the audio circuit and the alarm circuit; the buzzer is connected in parallel with the alarm circuit and the audio circuit, the controller, the indicator light, the audio circuit, the buzzer and The alarm circuit is arranged in the box body.

Working principle of the present utility model, according to the pressed time length of doorbell button switch, distinguishes whether it is the start of alarm and doorbell. When the doorbell switch is pressed for a short time, the controller judges the empty box based on the short-term current, and then starts the audio circuit, causing the doorbell to ring and the indicator light to turn red. If you press the doorbell switch for a long time, the controller will send a signal to the alarm circuit according to the signal sent, so that the buzzer connected to the alarm circuit will send out an alarm sound, and at the same time, the red light of the indicator light will flash quickly to alert outsiders. hint.

The beneficial effect of the utility model is that it can be used as a doorbell, and has the function of alarm and anti-theft, and the utility model has a simple structure and is convenient to use.

Description of drawings:

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is a schematic diagram of a module of a doorbell alarm of the present invention.

Detailed ways:

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

Referring to Fig. 1, a doorbell alarm mainly consists of a box body, a controller 1, an audio circuit 2, a buzzer 5, a doorbell button switch 4, an indicator light 6 and an alarm circuit 3; 4. The circuit connection between the audio circuit 2, the indicator light 6 and the alarm circuit 3, the controller 1, the audio circuit 2, the buzzer 5 and the alarm circuit 3 are set in the box body; the indicator light 6 is placed on a corner of the box body , used to attract people’s attention; the doorbell button switch 4 controls the start of the audio circuit 2 and the alarm circuit 3; the buzzer 5 is connected with the alarm circuit 3 and the audio circuit 2 in parallel.

During use, the doorbell button switch 4 can be installed inside and outside the house respectively. When someone comes from the outside, press the doorbell button switch 4 for a short time, and then the controller 1 judges according to the time pressed, and then sends a start signal to the audio circuit 2. signal, so that the buzzer 5 connected to the audio circuit 2 sends the doorbell music, and at the same time, the indicator light 6 is red. When the owner in the house has a thief in the house at night or during the day, he can press the doorbell switch 4 for a long time, and the controller 1 sends an alarm signal to the alarm circuit 3 according to the judgment, so that the buzzer 5 connected to the alarm circuit 3 sends out an alarm signal. Alarm sound, meanwhile, indicator light 6 flickers fast, and the passerby outside house has emergency situation in house.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
