Abstract

The utility model discloses an automatic counting mailbox, which comprises a mailbox base body, a letter drop and an automatic counting system, wherein the automatic counting system comprises a photoelectric switch, a single chip microcomputer and a digital display tube. When feeding letters into the mailbox, the letters jump through the signal sent by the photoelectric switch, the signal is transmitted to the single chip microcomputer which performs counting after receiving the signal and leads the digital display tube to display the current total number of the letters. The mailbox has the functions of automatic recording of letter number, is convenient for the user to timely check the letters, adopts a battery for power supply and has simple and convenient operation.

Description

A kind of automatic counting mailbox

Technical field

The utility model relates to a mailbox, particularly one counts mailbox automatically.

Background technology

The Mailbox that prior art is used generally only is provided with the opening of a delivery letter box, newspaper, and the existing mailbox that uses does not have display unit, the user can only open mailbox door can know that just the inside has or not mail, use for the user like this and have inconvenience, Chinese patent 02293704.8 improves this class mailbox, its technical scheme is that casing is provided with peep hole, and is fixed with supporting plate by Flexible Connector in casing, and the show label corresponding with peep hole arranged on the supporting plate.When letter is put into, effect bottom plate in its weight moves down, make the show label of letter corresponding with the peep hole position on the casing, make the demonstration of letter, the unnecessary like this mailbox of opening just can know that mailbox has or not mail, but this Simple Design can not show the mail number in the mailbox, and the easy device reliability of this machinery is not high.

Summary of the invention

The purpose of this utility model provides a kind of automatic counting mailbox that can count and conveniently consult the mail situation automatically.

In order to achieve the above object, the utility model is counted mailbox automatically and is comprised the mailbox matrix, goes into casually, one automatic counter system, wherein this automatic counter system comprises an optoelectronic switch, a single-chip microcomputer, and a digital display tube, when when mailbox is thrown in mail, the signal generation saltus step that mail is sent by optoelectronic switch, this signal sends single-chip microcomputer to, counts behind the single-chip microcomputer acknowledge(ment) signal, and make charactron show current mail sum

In order to reduce the loss of battery, this automatic counter system also can comprise an electricity saver, when mailbox is in for a long time the not time spent, this number system can be closed the demonstration of charactron, and when mail dropped into, charactron was lighted again, and show the mail sum simultaneously, when the user need consult mail in the mailbox, charactron was lighted, and showed mail number in the current mailbox.

Because the utility model adopts above-mentioned automatic counter system, and the advantage that this utility model has is:

This mailbox has the function of automatic record mail number, can make things convenient for the user can in time consult mail; And mailbox adopts powered battery, and is simple to operation.

The specific embodiment

Referring to Fig. 1, automatic counting mailbox 1 of the present utility model comprises mailbox matrix 11, go into casually 12, one automatic counter system 13 is (shown in Fig. 2, in the mailbox matrix 11), when the postman from going into casually 12 when dropping into mails, automatic counter system 13 is counted it, show the mail number on display screen 16, check mail in order to further facilitate the user, the utility model also comprises checks mail button 14, and the button 15 of unpacking, by checking that mail button 14 can check the mail number on the display screen 16, and the button 15 of unpacking, the unpacking button when being used for the user and obtaining mail.

In order more at large to narrate structure of the present utility model, Fig. 2 is the circuit diagram of automatic counter system of the present utility model, as shown in Figure 2, this automatic counter system 13 comprises an optoelectronic switch 131, one single-chip microcomputer 132, an and digital display tube 133, wherein optoelectronic switch 131 places into 12 place's (not shown)s casually, drop in the mailbox 1 to go into casually 12 o'clock as mail, LED1 in the described optoelectronic switch 131 is blocked, this optoelectronic switch 131 gives single-chip microcomputer 132 inputs a high potential signal, single-chip microcomputer 132 adds up described signal is treated, then the decoder 1331 of accumulative total through digital display tube 133 is presented on the display tube 16, comprises 3 display tubes 16 in the present embodiment, the multipotency of this display tube writes down 999 envelope mails;

When not having mail to drop in the mailbox 1, what optoelectronic switch 131 was given single-chip microcomputer 132 inputs is low-potential signal, and single-chip microcomputer 132 does not add up to its mail number, therefore, does not also add up at digital display tube 133 corresponding demonstration numbers.

The utility model is for convenient user, also include letterless display system 17, as shown in Figure 2, this display system 17 comprises LED2, and LED3 is connected with single-chip microcomputer 132, when single-chip microcomputer 132 receive be low-potential signal always the time, the green light LED 2 that just drives in the display system 17 is luminous, when the signal that receives when single-chip microcomputer 132 had high potential signal, the red-light LED 3 that just drives in the display system 17 was luminous, and convenient like this user knows and has or not mail in the mailbox.

The utility model also comprises an electricity-saving structure, when mailbox does not use for a long time, the demonstration that shows charactron 133 is closed in single-chip microcomputer 132 instructions, when mail drops into, import high potential signal once more at optoelectronic switch 131, single-chip microcomputer 132 drives demonstration charactron 133 once more and lights, and also be connected with at single-chip microcomputer 132 and check button 1321 and unpacking button 1322, when opening mailbox, the user opens the button 1322 of unpacking, connect the stationary nodes in the single-chip microcomputer 132 this moment, drive the mail number that current mailbox was lighted and shown to charactron 133 again this moment, the mail quantity that charactron 133 shows when shutting mailbox will be cleared, and red-light LED stopped after 3 flicker several seconds, and knowing has till the mail input.

Above-mentioned mailbox has automatic counter system, can make things convenient for the user in time to consult mail, solves a problem promptly, and consults mailbox thereby avoid the user to forget because of being busy with one's work, and mailbox adopts powered battery, and is simple to operation.

The above person is the utility model most preferred embodiment only, is not to be used to limit scope of the present utility model, and all equivalences of being done according to the utility model claim change or modify, and are all the utility model and contain.
