Abstract
The utility model discloses a kind of mailbox indicating circuit, comprise indicator lamp (1), power supply (2), wire (3), also comprise pressure sensor (4) and optoelectronic switch (5), indicator lamp (1), power supply (2), pressure sensor (4) and optoelectronic switch (5) are connected in mailbox through wire (3) and form a series circuit.The utility model can save people and all go to open mailbox every day and look into the trouble seeing if there is keepsake, also can avoid not going for a long time opening the phenomenon that mailbox causes important keepsake to incur loss through delay, when user passes by mailbox at every turn, whether there is pilot light as long as take a fancy to out and away at a glance, just can know whether that needs go to open mailbox pickup.
Description
Technical field
The utility model relates to a kind of indicating circuit, is specifically related to a kind of mailbox indicating circuit.
Background technology
The common part of city commercial, house and office buildings sets up the mailbox corresponding to each resident family or unit, in order to throw in the class keepsake such as mail, newspaper, magazine of user.When user is at every turn near mailbox, can go in the past to open mailbox, and check and wherein whether have keepsake to drop into, to have, take away.In fact, a lot of mailbox is not have every day keepsake to drop into, and therefore user needs pickup from mailbox every day, and for the user seldom having keepsake, it is a kind of futile for going before every day to open mailbox, so many users go to check a mailbox every a few talent.But so, sometimes also can incur loss through delay important keepsake.Therefore need a kind of mailbox message indicating device, without the need to opening mailbox, user just can be allowed out and away to see in mailbox and dropped into keepsake, having, open mailbox pickup, without then not going to comprehend.
The patent No. is that patent discloses in a kind of show case automatically of cn102078127A has letterless mailbox, by casing 2, mailbox door 3 and mail dispensing port composition, casing 2 inner bottom part is provided with hinge 9 and spring 10, pole 7 is connected with box house bottom by hinge 9, pole 7 top is provided with sign board 5, and spring 10 other end is connected with bottom rectangular slab 8.This kind of mail display mailbox, comes with some shortcomings, and as higher to the sensitivity of spring, if mail kicks the beam or overweightly will cause mistake display with presence or absence of mail, the spring members time is more aging more serious, and mistake with presence or absence of mail can be caused equally to show.
Summary of the invention
The utility model provides a kind of mailbox indicating circuit, to overcome mail mistake display in prior art, to be inconvenient to deficiencies such as checking, the utility model technical scheme provided of dealing with problems is as follows: a kind of mailbox indicating circuit, comprise indicator lamp 1, battery 2, wire 3, also comprise pressure sensor 4 and optoelectronic switch 5, indicator lamp 1, power supply 2, pressure sensor 4 and optoelectronic switch 5 are connected in mailbox through wire 3 and form a series circuit.
Described pressure sensor 4 is positioned at box bottom centre position, allow all be delivered to mail in mailbox all with its releasing, thus improve the accuracy of mailbox indicating circuit;
Described indicator lamp 1 is positioned at the edge of mailbox drop, facilitates user to check in mailbox whether have mail;
Also increase a switch 6 in described circuit, switch, with closed, when user does not need to use mailbox for a long time, be in off-state, can save electricity consumption by the connection being used for controlling whole circuit;
Preferably, switch 6 is positioned at mailbox outside, and user can directly disconnect or turn on-switch, convenient operation.
Red bulb generally used by described indicator lamp, conveniently observes from afar.
The utility model provides a kind of circuit and whether has thrown in the information of the class keepsakes such as mail for showing in mailbox, when indicator lamp is bright indicate keepsake, user is guided to open mailbox pickup, indicator lamp does not work and represents in mailbox when not having keepsake, does not allow user go vainly to open mailbox.The utility model can save people and all go to open mailbox every day and look into the trouble seeing if there is keepsake, also can avoid not going for a long time opening the phenomenon that mailbox causes important keepsake to incur loss through delay, when user passes by mailbox at every turn, whether there is pilot light as long as take a fancy to out and away at a glance, just can know whether that needs go to open mailbox pickup, for saving time mailbox user, save worry, laborsaving.
