Claims (1)

[Claims for Utility Model Registration] (1) It is attached in relation to the neck and handle of the toothbrush, and detects the pressing force applied to the neck during brushing, and when the pressing force reaches a set value, a brushing pressure detection section that outputs an electrical signal; a brushing motion detection section that detects vibrations or scraping sounds accompanying the brushing motion; and an output signal of the brushing pressure detection section that converts the electrical signal output from the brushing motion detection section into A toothbrush with a counting function, comprising: a control section that counts under the control of the control section; and a display section that displays the results counted by the control section. (2) The brush part including the neck part is formed separately from the handle part, and convex parts with approximately semicircular longitudinal sections are formed on both sides in the thickness direction at appropriate locations on the proximal end of the neck part, , a mounting hole into which the neck portion can be inserted is formed inwardly from one end, and a recess into which the convex portion can be fitted and locked is formed at a proper position on the inner surface of the mounting hole, and The toothbrush with a counting function according to claim 1, wherein a brushing pressure detection section is provided on the inner surface of the mounting hole located near the base end of the brush section. (3) The toothbrush with a counting function according to claim 1 or 2, which uses a keyboard switch as the brushing pressure detection section. (4) The toothbrush with a counting function according to claim 1 or 2 of the above-mentioned utility model registration, wherein a strain gauge is used as the brushing pressure detection section to make the setting value of the brushing pressure variable. (5) The toothbrush with a counting function according to claim 1 or 2 of the above-mentioned utility model registration claim, which uses a piezoelectric element as the brushing pressure detection section. (6) The toothbrush with a counting function according to claim 5, wherein the brushing pressure detection section has the function of a brushing operation detection section.
