Abstract

The utility model discloses a pencil box with an alarm means, which comprises a box cover and a box body. A pen placing gutter and an alarming circuit board are arranged in the box body, and the alarming circuit board is provided with a cell, a normally open switch, a normally closed switch, a speech sound IC and a loudspeaker which are orderly connected, wherein the normally closed switch is installed in the pen placing gutter and controlled by a pen, and a touching block which controls the normal open switch is arranged on the box cover. The pencil box with an alarm means of the utility model can check whether the pen is put in the pencil box in time when the pencil box is tightly closed and put away. If the pen is not in the pencil box, the utility model can inform a student in time, so the phenomenon that the student forgets to carry the pen can not occur. Simultaneously, if the pen is lent to others, the utility model can also remind the student of asking back.

Description

The warning writing case

Technical field:

The utility model relates to a kind of warning writing case.

Background technology:

Pen is the indispensable stationery of student, but because sometimes others borrows also, perhaps own with after do not put into writing case and forget and stay at home or school, no matter which kind of reason is not with pen, all might influence student's study, more can be suddenly when especially taking an examination student very.

The utility model content:

The purpose of this utility model is to provide a kind of warning writing case that can remind the student with pen.The utility model comprises lid and box body, put a groove in the box body, one warning circuit plate is arranged in the described box body, battery, normal open switch, normally closed switch, voice IC, loud-speaker are arranged on this circuit board, they connect in turn, wherein normally closed switch is installed in and puts in the groove, by pen control, the contact block of a control normal open switch is arranged on the described lid.

The utility model operation principle is: if pen is arranged in the writing case, pen is depressed normally closed switch makes its disconnection, and entire circuit is in off-state, does not report to the police; If there is not pen in the writing case, normally closed switch is in on-state, if this moment, writing case was if cover tight, contact block on the stationery cover will act on the normal open switch in the stationery box body, make it closed, entire circuit is in conducting state, and voice IC will send warning, amplify by loud-speaker, can tell the student " not have pen ".According to student's custom, generally all can cover tight writing case when receiving writing case, just know that band does not have the band pen this moment at once.If writing case be open or cover, this moment normal open switch disconnect, do not report to the police, illustrate that the student does not accept writing case, do not influence the normal use of writing case.

Because the utility model warning writing case can be when stationery cover be tightly accepted, in time whether therein to find pen, if in time do not circulate a notice of the student in meeting, the student just can not occur having left behind the phenomenon of pen more like this, can in time remind the student to return if the while pen has been lent others yet.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a circuit diagram of the present utility model.

The specific embodiment:

Fig. 1 and Fig. 2 have reflected concrete structure of the present utility model, in conjunction with this two width of cloth as can be seen, the utility model warning writing case has lid 7, box body 6, have one to put a frid 8 in the box body 6, circuit board is placed on a frid 8 times, battery 1, normal open switch 2, normally closed switch 3, voice IC4, loud-speaker 5 are arranged on the circuit board, and they connect in turn.Wherein normally closed switch 3 is arranged on and puts in the groove 81, is controlled by pen, and pen is depressed this switch and made its disconnection when having, this switch connection that resets when not having.The contact block 21 of control normal open switch 2 is installed on the lid 7, and the position is corresponding with normal open switch 2, and normal open switch 2 preferably adopts dry-reed tube switch, the contact block 21 that be installed on the lid this moment is exactly a magnetic patch, this is higher more reliable than contact-making switch susceptibility, and cost is low, and fault rate is low.When stationery cover was tight, contact block 21 (magnetic patch) acted on normal open switch 2 (tongue tube), makes its connection, and it is inoperative that stationery cover does not cover when tight 21 pairs of normal open switch 2 of contact block, makes it still be in off-state.Guaranteeing that battery 1 has and do not have the function of pen warning just can realize that stationery cover is tight under the situation of electricity the time like this, and do not influencing the normal use of writing case, bringing great convenience to the student.
