Abstract

The invention discloses a toothbrush capable of judging tooth brushing actions and duration. The toothbrush comprises a detection device, a distinguishing device, a timing device and a sound module, wherein the detection device is used for detecting the inclination angle and a motion curve of the toothbrush; the distinguishing device is used for distinguishing validation or invalidation of the service condition of the toothbrush according to an acceleration signal and an angle signal which are output by the detection device; the timing device is used for generating a timing signal when the tooth brushing action is normal and recording tooth brushing duration of each action; and the sound module is used for whistling and reminding after a signal action is successfully completed and producing a reminding sound when the whole tooth brushing time is up to.

Description

A kind of toothbrush that can judge brush teeth action and duration

Technical field

The present invention relates to Intelligent life technical field, particularly relate to and a kind ofly can judge brush teeth action and the toothbrush of duration, and monitoring, differentiation, timing, sound module.

Background technology

Brushing teeth of most people generally felt brush with oneself at present, brushing teeth the duration, and the fermentation such as the number of times of brushing teeth, the dynamics of brushing teeth, toothbrush angle of inclination do not have correct arrangement.According to the difference at tooth position, do not distribute rational brushing time in addition.Low age bracket children particularly, correct teeth brushing way is a problem demanding prompt solution especially.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of toothbrush that can judge brush teeth action and duration.The signal of brushing teeth that this toothbrush can accurately be identified, and can detect the situation of brushing teeth, differentiation, timing, voice output, be the correct back-up surveillance of brushing teeth of user.

The technical solution adopted in the present invention is: the acceleration transducer of the arrangement on the brush holder of this toothbrush is for detection of motor message, angular transducer detects as for toothbrush angle of inclination, the pressure sensor of fine, soft fur root gathers fine, soft fur pressurized situation, timer is for brushing time timing simultaneously, after switching on power, the motor message that in one second, toothbrush acceleration transducer detects meets some, angular transducer detects correct toothbrush inclination angle, and pressure sensor detects pressurized situation, timer starts countdown, at timer, complete after the countdown data of setting, buzzer toot cry, point out this action of brushing teeth to complete, can carry out next action.If the acceleration that in a second, toothbrush produces is not enough, or without pressure data etc., timer is considered as invalid second, does not lower countdown data, until action is correct, continues timing.

Compared with prior art, the invention has the beneficial effects as follows and not only detect brushing time and the number of times of brushing teeth, and the dynamics of brushing teeth is also had to detection.Adopt countdown pattern, the every kind of posture of brushing teeth is set with to the countdown time, the time blows a whistle and reminds this action to complete after reducing to zero, avoids excessively brushing teeth tooth being damaged.In the frequency of brushing teeth, action norm, brushing time, dynamics prompting aspect has good detection to remind.

Accompanying drawing explanation

Fig. 1 is built-in circuit and the installation of sensors location drawing in toothbrush.

The specific embodiment

Toothbrush comprises head toothbrushes and toothbrush handle, and head toothbrushes and toothbrush are separable, and head toothbrushes inserts toothbrush key switch L is connected.In toothbrush handle, circuit is set, by duplet circuit supply, circuit comprises single-chip microcomputer timing module and buzzer module.Head toothbrushes back is shaped with SMD acceleration transducer and angle inclination sensor, and bristle root posts pressure sensor.In the present embodiment, adopt ball tilt switch, the method for brush teeth monitoring and prompting is inserted after brush holder at head toothbrushes, and each sensor starts to power on.Detection module detects, movement locus, and angle tilts, and dynamics is pressed signal, only 3 all under normal circumstances.Buzzer piccolo one sound, timer starts countdown, and pilot process is if any part getting stuck or poor form, after detecting, buzzer meeting dichloro-diphenyl-dichlorothane 3 acoustic alarms, the module of countdown simultaneously stops regressive counting, after knowing that action is again normal, continue timing, buzzer does not ring simultaneously.After timing completes, long the dripping of buzzer reminded, and enters next action of brushing teeth, and starts countdown again.The present embodiment is divided into into 10 operating positions.Be respectively: 1, left outside upper, 2, left outside under, 3, upper in a left side, 4, in a left side under, 5, right outside upper, 6, right outside under, 7, upper in the right side, 8, in the right side under, 9, upper facies occlusalis dentis, 10, lower facies occlusalis dentis, each face countdown 15 seconds.

Claims

1. the toothbrush that can judge brush teeth action and duration, is characterized in that: toothbrush is comprised of brush holder and brush two parts.The bristle root of brush is provided with deformation formula pressure sensor; The outside handheld terminal of brush holder is equipped with SMD acceleration transducer and key switch.Brush holder is that its inner chamber of hollow structure is equipped with power supply electronics and single chip control module, and the action of brushing teeth is divided into 10 operating process.Separately there are detection, differentiation, countdown, sound module to be installed on brush holder place.Brush holder handheld terminal is equipped with key switch, presses rear sensor and starts to power on, and each module enters mode of operation.

2. a kind of action and toothbrush of duration of can judgement brushing teeth according to claim 1, is characterized in that: brush body can inborn ability, by electronic power, and the process steps of brushing teeth, brushing time that can each step of countdown.
