On the other hand, the elapsed time of brushing and the estimated time to end brushing may be displayed when the user is delivered as having started brushing through the intensity detecting unit 112 of the smart electric toothbrush 110. In addition, the scheduled end time of brushing may vary depending on the progress of brushing by the user. For example, if the user does not touch the bristles 110b to the teeth more than the reference strength, the driving unit 113 does not work, so the scheduled time to end brushing may increase.

The user's teeth information is stored in the storage unit 125. For example, the storage unit 125 stores information such as a tooth picture, number of teeth, and location of teeth for each user. Also, a manual for brushing teeth is stored in the storage unit 125, and information such as a user's daily brushing frequency, brushing results, and brushing images is also stored. In addition, information such as a brushing reference time and a reference strength is also stored in the storage unit 125. Here, the brushing reference time may be set and stored differently for each tooth, and may be set and stored differently for each user. For example, the brushing time of the molars may be set longer than the brushing time of the front teeth.

The control unit 126 may receive the user's brushing information from the smart electric toothbrush 110, determine whether the teeth are uniformly wiped, and compensate accordingly. Specifically, the control unit 126 may receive images captured from the camera unit 111 in real time through a network. In addition, the control unit 126 may receive information on whether the tooth contact and the contact strength of the bristles 110b of the smart electric toothbrush 110 are received from the strength sensing unit 112. For example, the control unit 126 receives information such as information and contact strength of the tooth currently being brushed from the camera unit 111 and the intensity detection unit 112, and the reference time and reference intensity stored in the storage unit 125 Compare. As a result of the comparison, when it is determined that the user performs brushing of the corresponding tooth over the reference time and the reference strength, the control unit 126 compliments the guide unit 121 with praise messages such as'well done','good', etc. You can order the sticker to be displayed. In addition, when it is determined that the user has performed the brushing of the corresponding tooth below the reference time and the reference strength, the control unit 126 may include a cheer message such as'Please give me a little more','Wipe a little harder', etc. You can order to show the cheer sticker.

In addition, the control unit 126 receives information such as an administrator's praise message, support message, delivery information, request, etc. from the administrator terminal 130 to the user through the guide unit 121 and/or the brushing position display unit 122 I can tell you. For example, when the controller 126 receives a request to brush the upper right molar further from the manager terminal 130, the control unit 126 instructs the brushing position display unit 122 to generate a tooth decay icon I on the corresponding tooth, and the guide unit In (121), a letter may be told to wipe the tooth again.

In addition, when it is determined that the user has brushed all of the teeth beyond the reference time and the reference intensity, the control unit 126 instructs the guide unit 121 to stop brushing, and the guide unit 121 sends a tooth brushing end message to the user Can be displayed. In addition, the control unit 126 may instruct the driving unit 113 of the smart electric toothbrush 110 to stop operation, thereby terminating the brushing.
