Abstract
A kind of lavatory lost property alarm, stub, bulky spring, pressure sensor, support board, conducting wire, single-chip microcontroller, hairspring, plastic shell, metal bolt, bulky spring covers on stub, stub is fixed on pressure sensor, pressure sensor upper end is fixed with support board, single-chip microcontroller is connected with pressure sensor and metal bolt by conducting wire, hairspring covers in metal bolt, and metal bolt is inserted in plastic shell.The advantages that the utility model includes low in cost, and privacy is strong, alarms high-efficient, energy saving.
Description
Technical field
The utility model relates to a kind of daily necessity, especially a kind of lavatory lost property alarm.
Background technique
It is well known that current more liquid public place this in public places, property Loss Rate is very high, this report
Alert device is intended to alarm immediately when loss event occurs, while not invasion of privacy.
Summary of the invention
The purpose of the utility model is to provide a kind of lavatory lost property alarms
The utility model mainly include stub, bulky spring, pressure sensor, support board, conducting wire, single-chip microcontroller, hairspring,
Plastic shell, metal bolt, bulky spring cover on stub, and stub is fixed on pressure sensor, pressure sensor upper end
It fixes with support board, single-chip microcontroller is connected with pressure sensor and metal bolt by conducting wire, hairspring covers in metal bolt,
Metal bolt is inserted in plastic shell.
In use, there is following working condition.If without placing article on support board, stub does not connect with lower Square wire
Touching, entire circuit are in open circuit, and alarm does not work；If placing article on support board, when user's enabling is to be walked, article
Compression bulky spring connect stub with lower Square wire, and people stirs metal bolt compression hairspring, so that metal bolt and a left side
The connection of side conducting wire, entire circuit are in access, and at this moment pressure sensor feels the pressure of article, and issue an electric signal and give
Single-chip microcontroller, single-chip microcontroller control the buzzer warning of itself, and prompting has article to be lost in support board.
Compared with the prior art, the utility model has the following beneficial effects: low in cost, privacy is strong, alarms high-efficient, section
About energy consumption.
