Brush head replacement indication method of electric toothbrush and electric toothbrush with brush head replacement indication function

Abstract

The invention discloses an indication method for judging whether a brush head needs to be replaced or not according to the actual tooth-brushing usage situation of a user. The indication method comprises the steps of obtaining tooth-brushing data of the user, working out the loss value of the brush head according to the tooth-brushing data of the user, and sending the indication that the brush head needs to be replaced to the user when the loss value of the brush head is larger than or equal to a predefined threshold. The invention further provides the electric toothbrush with a brush head replacement indication function. Based on the toothbrush usage data including basic wear value of brush bristles, overpressure wear value, tooth-brushing duration and the influence of the toothbrush storage duration on the loss of the brush bristles, the service life of the brush head is designed from the view of the user, and the economical efficiency and environment friendliness are better.
