Description

A kind of use date prompt device

Technical field: the utility model relates to a kind of prompting instrument, particularly a kind of use date prompt device.

Background technology: at present in the supermarket, family and some public places, problem how long often appears not knowing when to store and store in stored food, potable water etc.Edible under the situation like this, often there is hidden danger in the health to human body, because expired food has very big harm to human body.Use very generally at home such as water dispenser, it has brought easily simultaneously to people, also exists some hidden danger because the water dispenser bottled water operating period be generally two weeks, the longest can not be above one month.But,,, drink then harmful again to people's health if exceeded 30 days because people's negligence of management does not know how long bottled water has changed under a lot of situations at the employed water dispenser of family, particularly office and some public places.Food such as the meat that displays in the show cabinet of supermarket, vegetables for another example, the food of being preserved in the houshold refrigerator etc. all exist and do not know to store problem how long.

Summary of the invention: the purpose of this utility model provides a kind of use date prompt device, in order to solve effectively and overcome work on hand, the life in above-mentioned drawback.The purpose of this utility model realizes with following technical scheme: by power circuit and the time controller that is connected successively, LCD driver, be used for that timing shows and time display four parts of the time showing of guaranteeing the quality constitute, time controller is connected with start key, key is set, raises key, down key and is used for the green LED of expression " in the shelf-life " and the red light emitting diodes of " exceeding the shelf-life "; Be laid with the window of signable " in the shelf-life " on the panel of the present utility model, the window that " exceeds the shelf-life ", the window of " timing demonstration ", the window of " shelf-life demonstration ", " day; the time; divide " window and the window of " day ", above-mentioned said being used in the window that the green LED of expression " in the shelf-life " and red light emitting diodes that expression " exceeds the shelf-life " be arranged at the window of signable " in the shelf-life " and " exceeding the shelf-life " respectively, the window of signable " timing demonstration " is arranged at the left side that is used for the time display that timing shows, the window of signable " shelf-life demonstration " is arranged at the left side of the time display of the time showing that is used to guarantee the quality; Above-mentioned said start key, key be set, raise key, below down key and power switch are located at the time display panel.

The course of work: power-on switch or connection AC power, press key is set, carry out the guarantee date setting earlier, press start key then and start timing.During timing numerical value was less than shelf-life numerical value, green LED kept Chang Liang, can highlight in the shelf-life, and the prompting people can relievedly use.After timing numerical value was greater than shelf-life numerical value, then red light emitting diodes kept Chang Liang, can highlight to exceed the shelf-life, and the prompting people can not go edible again.

The utility model modern design, rational in infrastructure, marking object easily, particularly indicate food, drink is in the shelf-life, still exceeds the shelf-life, represents clear, come into plain view, reminds people knows whether all right relieved use, helps preventing that people from eating expired Food ﹠ Drink, guarantees healthy.The utility model applied range can be widely used in supermarket, hotel, family and some public places etc.Particularly in supermarket, hotel, use, more can embody the thought of supermarket, hotel " consumer paramountcy, people-oriented ".
