Description

TECHNICAL FIELD [0001] The present invention relates to a smart toothbrush,

The present invention relates to a smart toothbrush and a control method thereof. More particularly, the present invention relates to a smart toothbrush and a control method thereof, which provide a function of assisting in obtaining brushing information and performing brushing more smoothly according to the obtained information.

In recent years, the burden of the national government has been increasing due to the increase in social and welfare demand, such as the increase in the burden of the productionable population due to the aging of the population and the increase in the medical expenses of the elderly. Ubiquitous / mobile healthcare technology, which is a fusion of technology, has been gaining much sympathy for the prevention and management of diseases should be given priority.

Life-style disease is an unhealthy lifestyle

, And diabetes, hypertension, and obesity are examples of the disease. Among these lifestyle-related diseases, prevention and management of oral diseases are more important than other diseases, and effective management alone has proved effective.

Typical oral diseases are known as dental caries, periodontal disease, and malocclusion. Double dental caries and periodontal disease are caused by deposition of bacteria, ie, plaques, in the oral cavity.

Therefore, in the prevention and treatment of dental diseases, the management of the bacterial membranes in the oral cavity is of paramount importance. It is known that mechanical methods, ie, physical methods including brushing, are the most effective methods of managing bacterial membranes. Regular dental visits are carried out without discomfort, and toothbrushing training is most importantly emphasized in scaling procedures for removing calculus.

Although the importance of brushing is emphasized every time the dentist visits the clinic, and there is only a simple guideline according to age and oral condition in effective measurement and evaluation of brushing habits in general, There was a lack of technology development for effective management methods based on systematic and numerical data.

In the dental clinic, toothbrushing education is often stopped only once, and in the long term, the patient 's habits can not be corrected and the teeth are lost, resulting in malfunctions and aesthetic problems such as writing and pronunciation.

Recently, products for electric toothbrushes (ultrasound, vibration, etc.) are on the market in order to increase the efficiency of brushing teeth, but there are many opinions about efficiency and stability.

For example, recently developed electric toothbrushes have been used to evaluate the quality of toothbrushes by only providing feedback on the brushing time to the user, thereby evaluating the average manual toothbrushing, however, Are not considered. In addition, even if brushing time is long, if you can not effectively wipe out all the teeth, you will not be able to eliminate the possibility of a reward.

Therefore, in order to prevent and manage such oral diseases, a variety of IT / health-related technologies are required to be fused to provide quantitative measurement of the mouthwash and personalized management.

The beginning of the quantitative measurement of brushing was the first measurement with a pressure sensor attached to the toothbrush. However, no quantitative evaluation of pressure and brushing was done.

Prior art thereafter has been brushing monitoring prior art to monitor brushing and determine how well the user was brushing, but there is still a need to improve the accuracy and equipment cost of existing monitoring devices.

In addition, the brushing end time suitable for the user can be calculated according to the changed breath concentration, and the smart toothbrush 100 can set and guide the brushing to be maintained for the calculated ending time of the brushing. (S110)

In addition, the processor 270 may also calculate the residual toothpaste amount in the measurement of the bad breath concentration, and may control to output a message for guiding more mouth opening when the value is larger than a predetermined value.

On the other hand, the processor 270 may calculate and output a score indicating the quality of the mouth rinsing based on the rinse information after the brushing is finished, and may output a training guide when a problem is detected. (S204)

That is, the processor 270 may calculate the score of the quality of the toothbrush to be a numerical score so as to confirm whether the toothbrush is in the normal level or the abnormal level, and then display the score on the display 280.

In addition, when the user wipes a specific mouth area, the processor 270 can output an image of the brushing pattern suitable for a specific mouth area to the training image to train the user when the head does not move in the proper direction.

For example, referring to Fig. 9, when a brushing pattern in which the user wipes the molar teeth in an inappropriate direction is detected, an image representing the movement of the toothbrush brushing the correct molar teeth may be output to the display 280. [

In addition, the processor 270 may continuously provide a cleaning history output function for storing the toothbrushing information, recording the toothbrushing information, and then recording the toothbrushing information, and then outputting the brushing information when the user selects the toothbrushing information. (S205)

For example, the processor 270 may determine the amount of toothbrushing time, the number of mouth rinses per day,

At this time, the processor 270 may transmit the tooth brushing history information to the terminal 200 of the user (for example, the parent) through the communication unit 220 to assist the administrator in training the user to brush the toothbrush .

In summary, the smart toothbrush 100 and the terminal 200 can improve the tooth health of the user by providing various mouthwash assist functions that can accurately measure the quality of the user's mouthwash and improve the quality of the mouthwash .
