Abstract
The utility model discloses a reminding device, which belongs to electronic alarm class. The utility model comprises a battery, a pendulum type switch, an electronic alarm device, and a buzzer which are arranged in a casing. The reminding device controls the electronic alarm device to make the buzzer sound by the pendulum type switch to remind people. The utility model has the advantages of simple structure, easy production and manufacture, and low cost. The reminding device which is especially suitable for primary and secondary school students is an ideal tool for preventing from myopia.
Description
The utility model relates to a kind of electronic alarm class.
In order to prevent myopia, people just must constantly remind the distance of oneself noting between maintenance eyes and the books constantly in the process of study.At present, main protection measure is to make it form better learning naturally and write posture to also have to having given free rein to of not forming a habit with compulsory way.
The purpose of this utility model people the most provides a kind of reminiscences that can make learner in time rectify study and year reading posture.
This reality and novel formation are: by the electronic alarm device of a pendulum-type on-off control, buzzer and shell and battery and the electronic reminding device formed, below in conjunction with accompanying drawing in addition narration at length of structure of the present utility model.
Fig. 1 is an installing sketch map of the present utility model;
Fig. 2 is this reality and novel circuit theory diagrams;
1 is the hook-type shell in Fig. 1, and 2 are provided in a side of the pendulum-type switch in the shell, the 3rd, battery, the 4th, electronic alarm device wiring board, the 5th, buzzing.
Embodiment: angle shape shell 1 to adopt and the plastics compacting, in shell, be divided into battery compartment, electronic warning 2 device wiring board storehouse and pendulum-type switch storehouses, be to connect battery arbitrary end battery lead plate on the outer casing inner wall that is flapped toward about in pendulum-type switch storehouse, the pendulum-type switch is with a CK-UN3561 or the integrated method of KD9561, NPN type audion and the electric capacity that is connected transistor emitter and connect the resistance of transistor base, integrated method has three input lower limbs and three output legs, input is connected with battery through audion, outfan connects buzzer respectively, with in the pendulum-type switch just, negative electrode.Two K switch are set in circuit
1, K
2, K
1Be the battery cut-out switch of circuit, K
