Rotary toothbrush with vibration

Abstract

The invention relates to a flat motor for manufacturing toothbrushes. The radius of an armature disk of the motor is 4 to 6 times larger than the longitudinal diameter of a strip motor, and an eccentric wheel is fixed on the armature disk. The arrangement of the flat motor can make a shaft of the motor and the brush surface of a toothbrush form an angle of 90 degrees mutually, so the motor can also be made into a rotary toothbrush, when the eccentric wheel fixed on the armature disk is removed, the shaft of the motor is directly connected with the disk surface of the toothbrush, and then the brush can be driven to rotate to brush the teeth. Brush fur is directly connected with the armature disk, and the eccentric wheel of the flat motor is sealed in a shell of the motor and can be molded by injection and fixed with the brush fur.

Description

technical field [0001] The invention relates to a daily sanitary appliance, in particular to a toothbrush capable of rotating and vibrating when brushing teeth. Background technique [0002] The Chinese patent has published a specification whose application number is 200510104131.5, which discloses a toothbrush with a vibrating head. Because the vibration motor of the toothbrush is bar-shaped, the eccentric hammer of the vibration motor is on the outer shaft of the motor, along the Vibrating in the radial direction, as a result, the movement direction of the bristles cannot concentrate on the tooth groove direction, and the radius of the motor is small and long, so it can only be installed along the parallel direction of the toothbrush. That is to say, the shaft of the motor cannot be perpendicular to the brush surface at an angle of 90 degrees, so it cannot be directly connected to the brush plate and drives the brush to rotate.

Because the vibration motor of the toothbrush is bar-shaped, the eccentric hammer of the vibration motor is on the outer shaft of the motor, along the Vibration in the radial direction, as a result, the movement direction of the bristles cannot concentrate the force on the direction of the tooth groove, and the radius of the motor is small and long, so it can only be installed along the parallel direction of the toothbrush

That is to say, the shaft of the motor cannot be perpendicular to the brush surface at a 90-degree angle, so it cannot be directly connected to the brush plate and drive the brush to rotate
