Abstract

A personal electric cleaning tool comprises a handle part accommodating a driven element and a head part connected with a supporting body for supporting a cleaning element, wherein the supporting body limits a first joint shape; and a transmission rod with the end far away from the head operably connected to the drive element and the end close to the head part fixed with a drive wheel which limits a second joint shape matched with the first joint shape; when the transmission rod is driven by the driven element, the supporting body conducts reciprocating rotation with the drive wheel, wherein one of the first joint shape and the second joint shape is a shape limited by two opposite conical tooth surfaces on a cone gear, and the other of the first joint shape and the second joint shape is a shape limited by a conical tooth engaged with the two conical tooth surfaces. Through the personal electric cleaning tool, the volume of the head part of the personal electric cleaning tool is designed to be smaller, so that a user can more comfortably use.

Description

technical field [0001] The invention relates to a personal electric cleaning tool, in particular to an electric oral cavity cleaning tool, and more specifically, the oral cavity electric cleaning tool is an electric toothbrush. Background technique [0002] Various techniques exist in the art for converting the rotational output of a motor or other power source into the specific motion required for a desired personal power cleaning implement. Many technologies include a rotating shaft as part of the drive train. The rotating shaft can rotate, swing or reciprocate. The shaft is coupled to the carrier of the cleaning elements of the personal power cleaning tool. Usually, the carrier of the cleaning element is driven by the rotating shaft in a rotational or oscillating manner about an axis perpendicular to the longitudinal axis of the rotating shaft. [0003] As a personal electric cleaning tool, electric toothbrushes offer many oral hygiene benefits. For example, a toothbr...
