Description
Technical field
The utility model is related to circuit field, more particularly to a kind of shield tooth system of children electric toothbrush.
Background technology
With the improvement of living standards, material life is extremely abundant, the most important factor of children's decayed tooth is exactly child mouthful
What chamber health was done be not thorough and caused by, and children's preference sweet food again contains a large amount of sugar and starch in sweet food, such as candy, skilful
Gram force, biscuit and cake etc., the big sweet food of these stickiness are easily adhered on facing, provide and fill for the cariogenic bacteria in plaque
The nutrient of foot also creates " good condition " for decayed tooth, and the organic acid cariogenicity generated after metabolism is very strong, this is also now small
The one of the major reasons that child's decayed tooth increases.
In order to which pre- child-resistant decays tooth, parental education and children is supervised to brush teeth, to clean removing oral bacteria, electric toothbrush because
Its good cleaning effect obtains the favor of parent, but because children are often poor in terms of self-discipline, it can not be according to correct
Teeth brushing way brush teeth, sometimes even toothbrush be contained in play in the mouth, be easy to cause electric toothbrush so for a long time to youngster
The tender tooth of childishness and gum cause the damage of bigger, influence teenager teeth health, or even because brush teeth it is improper caused by gum damage
Wound, cause the tooth basis after growing permanent teeth loosely, it is long extraordinary-looking etc., affect child growth and physical and mental health.
In the prior art, the following disadvantage of electric toothbrush generally existing：One, toothbrush is perceived only with acceleration transducer
Action, to judge whether electric toothbrush stops always at some point, the perceptual structure is too simple, and toothbrush is not in sometimes
In oral cavity, electric toothbrush still starts, and be easy to cause erroneous judgement and reports an error；Two, children usually forget to brush teeth after meal, it is difficult to cultivate children
The custom that timing is brushed teeth；Three, the noise that the motor in electric toothbrush generates is larger, is unfavorable for protecting Pediatric Oral Emergency health, uncomfortable
Suitable children use.
In view of this, the present inventor specially devises a kind of shield tooth system of children electric toothbrush, thus this case generates.
Utility model content
The purpose of this utility model is to provide a kind of shield tooth systems of children electric toothbrush, are brushed teeth not with solving children

With the above structure, the utility model has the advantages that following：
One, after the MOS switch unit of the utility model is opened, MCU units control motor action, and conduction hairbrush carries out high speed
Work is vibrated, 3-axis acceleration sensor, three-axis gyroscope and magnetic sensor mutual cooperation accurately perceive the action brushed teeth,
By each low-pass filter circuit feedback signal to MCU units, timing module holds time to judge according to feedback signal level
The actuation time brushed teeth, if actuation time is insufficient, the second voice unit carries out insufficient prompt, and motor is stopped, waits for
Children continue to brush teeth after acting toothbrush again, if actuation time is overtime, the second voice unit carries out overtime prompt, and motor stops
The phenomenon that only working, continue to brush teeth after children act toothbrush again, erroneous judgement is avoided to report an error；
Two, the utility model enables the first voice unit timing prompting children brush teeth by RTC block, and culture children's timing is brushed
The custom of tooth helps to improve Pediatric Oral Emergency health；
Three, it is parallel with ceramic disc capacitor on the motor of the utility model, eliminates the noise at motor both ends, it can not only be to motor
It plays a protective role, and can preferably be suitable for children, help to improve Pediatric Oral Emergency health.
The utility model is described further below in conjunction with the drawings and specific embodiments.
