Abstract

A detecting device for detecting barriers behind a door includes a sensor for transmitting detecting signals to detect whether there is a barrier behind the door, an identifier for transmitting identification signals to identify whether the barrier behind the door is a living animal, and an alarm electrically connected with the sensor and the identifier for generating an inductive signal according to a detecting result of the sensor or an identification result of the identifier. As a result, the detecting device can detect whether there is any barrier behind the door and whether the barrier is a living animal through the detecting signals of the sensor and the identification signals of the identifier. If a barrier is behind the door, the alarm will generate a warning signal to notify the person who is going to open the door such that the person can carefully open the door.

Claims

1. A detecting device for detecting barriers behind a door, the detecting device comprising:

a sensor for transmitting detecting signals to detect whether there is a barrier behind the door;

an identifier for transmitting identification signals to identify whether the barrier behind the door is a living animal; and

an alarm electrically connected with the sensor and the identifier for generating an indicative signal according to a detecting result of the sensor or an identification result of the identifier.

2. The detecting device as claimed in claim 1, wherein the sensor is an ultrasonic wave sensor that transmits the detecting signals of ultrasonic wave

3. The detecting device as claimed in claim 1, wherein the identifier is an infrared identifier that transmits the identification signals of infrared rays.

4. The detecting device as claimed in claim 1, wherein the warning signal is in the form of light.

5. The detecting device as claimed in claim 1, wherein the warning signal is in the form of sound.

6. The detecting device as claimed in claim 1, wherein the warning signal is in the form of a Braille symbol.

7. The detecting device as claimed in claim 1, further comprising an additional alarm electrically connected with the sensor and the identifier for generating an additional indicative signal according to the detecting result of the sensor or the identification result of the identifier.
