Abstract
The utility model discloses a correcting device of sitting position, comprising a battery chamber, a mercury switch, a buzzer, a cover, a base and a self excitation oscillating circuit. The correcting device of sitting position is worn on a user to determine the best head part front rake automatically. The correcting device of sitting position has compact structure, comfortable wearing, not easy looseness and low cost, so the utility model is in particular suitable for correcting the sitting position for students and vehicle drivers.
Description
This utility model relates to the daily-use electrical appliance technical field, particularly a kind ofly is used to correct student's writing posture, prevents the correcting sitting posture device that the driver dozes off.
The student generally can both keep correct sitting posture at the initial stage of writing, and makes to keep a suitable distance between eyes and textbook, the exercise-book.But As time goes on, fatigue can appear in student's vertebra, concentrates for a long time in addition, and head can turn forward in spite of oneself, spinal curvature, thus incorrect sitting posture appears, student's vision and vertebra brought bad influence.The driver of night running dozes off especially easily, can cause vehicle accident, causes the loss of lives and properties.If can provide a kind of extension to wear alerting device easily to above-noted persons, just can avoid occurring bad consequence.Chinese patent application number is 86209624 Sleepy alarm, be wearing behind people's ear, when people's head too leans forward, just send sound equipment immediately, remind the wearing person to correct incorrect posture.This Sleepy alarm is made up of two button cells, mercury contact, Music Clip, buzzing sheet, and its Music Clip is contained in the square frame of bottom, and the buzzing sheet is contained in place, curved position, middle part, and buzzing sheet outside is equipped with fixed.The nonadjustable mercury contact of angle needs two button cells to make the working power of Sleepy alarm.Because this patent application fails fully to disclose its mounting structure content, thereby its concrete structure just is difficult to check on, only from mercury contact for fixing non-adjustable this point, be to satisfy difference, the requirement of user, and its cost is also than higher.
The purpose of this utility model is to provide in order to overcome above-mentioned weak point a kind of can adapt to the correcting sitting posture device that the different users requires the difference of sitting posture.
This utility model is that such correcting sitting posture device of realizing is by a button cell, battery compartment, the mercoid switch piezoelectric buzzer, lid, base and being used to produces the self-excited oscillator of an audio signal and forms, divide in the base and be separated with ante-chamber, the component cavity resonant cavity, battery compartment is contained in the ante-chamber left side by rotating shaft, a button cell is packed in the battery compartment middle part, mercoid switch is contained in the ante-chamber at base middle bent place, mercoid switch can upwards rotate 70 ° of angles around self rotating shaft from the upright position, there is a circular resonant chamber base right part, the resonator cavity right side or on, downside has a louver, a component cavity is arranged between ante-chamber and the resonator cavity, the element that is used to produce the self-excited oscillator of an audio signal is placed in the component cavity, and it is hook-shaped that the base upper end copies people's ear structure to cause.Mercoid switch top is forward and backward respectively a rotating shaft, article two, rotating shaft and mercoid switch housing tight fit and stretch in the housing and keep one section distance mutually less than built-in hydrargyrum spot diameter, it is fixing that the other end of two rotating shafts is done supporting movingly by two electric connecting plates respectively, these two electric connecting plates are tightened up by four plastic column rivet hots of base respectively, and the mercoid switch lower boss is exposed the base outside.One end of positive source sheet is fastened in the groove on base right side.The housing of base, lid, battery compartment, mercoid switch and the material of boss thereof can be polrvinyl chloride or polypropylene or ABS plastic.
Described self-excited oscillator is made up of an audion, two resistance, and the buzzing sheet adopts the piezoelectric ceramics buzzing sheet of the band feedback utmost point (three utmost points).
Advantage of the present utility model is that the placement location of mercoid switch is adjustable, and its setting range reaches 70 ° of angles, thereby has adapted to the shape of different people ear and the requirement of different use occasions, and user can be determined best head top rake voluntarily.Battery compartment can both can be placed button cell around the axle folding, and also double as on and off switch is because of its folding with convenience, so the loading and unloading button cell is very convenient.Owing to adopt the piezoelectric ceramics buzzing sheet of the band feedback utmost point, so self-maintained circuit is very simple, only with three elements, cost is very low.This correcting sitting posture device compact conformation, comfortable wearing, be difficult for getting loose, inexpensive, thereby be particularly suitable for the usefulness that student, driver make correcting sitting posture.
