Door-exiting prompter

Abstract

The invention discloses a door-exiting prompter. The door-exiting prompter includes a first human body induction circuit, a door-exiting confirmation circuit and a prompting control circuit which are arranged in a front-back manner; the first human body induction circuit inducts human body radiation signals, and outputs first electric signals to the prompting control circuit; the door-exiting confirmation circuit inducts the human body radiation signals and outputs second electric signals to the prompting control circuit; and when simultaneously receiving the first signals outputted by the first human body induction circuit and the second signals outputted by the door-exiting confirmation circuit, the prompting control circuit outputs electric signals to drive a circuit to emit prompting signals. The door-exiting prompter of the invention comprises the door-exiting confirmation circuit, so that the door-exiting prompter can emit the prompting signals after whether a user exists from a door is confirmed, and therefore, prompting of wrong signals can be greatly deceased, or even avoided.

Description

technical field [0001] The invention relates to an exit prompter which sends out a prompt signal when a person goes out, in particular to an exit prompter which sends out a prompt signal after confirming whether a person has gone out. Background technique [0002] Nowadays, many people will forget to bring important things such as keys and mobile phones when they go out, which will cause unnecessary troubles in life, and many people will forget to turn off gas, water taps, electrical appliances, etc., causing economic losses and even accidents; The going out prompter that sends prompting signal when people go out is particularly important. [0003] In the prior art, a "household going out prompting device" is disclosed, which is provided with an induction prompting circuit including an induction switch and a prompting device. After the induction switch is sensed and the induction prompting circuit is turned on, the prompting device sends out a prompting signal. In the techn...

[0002] Nowadays, many people will forget to bring important things such as keys and mobile phones when they go out, which will cause unnecessary troubles in life, and many people will forget to turn off gas, water taps, electrical appliances, etc., causing economic losses and even accidents; The exit prompter that sends out a prompt signal when people go out is particularly important

[0003] In the prior art, a "household going out prompting device" is disclosed, which is provided with an induction prompting circuit including an induction switch and a prompting device. After the induction switch is sensed and the induction prompting circuit is turned on, the prompting device sends out a prompting signal. In technology, when a person appears within the sensing range of the sensor switch, but does not go out, a reminder signal will also be sent out, so it is easy to send redundant or wrong reminder information, which may cause false triggering and cause troubles to the life of the user
