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
The present invention relates to a kind of daily hygiene sanitary equipment, the toothbrush that can rotate and vibrate during particularly a kind of brushing teeth.
Background technology
It is 200510104131.5 prospectus that Chinese patent discloses application number, this description discloses a kind of toothbrush with vibrating head part, because of the toothbrush vibrating motor is bar shaped, so the eccentric hammer of vibrating motor is on the outer shaft of motor, vibrate along radial direction, the direction of motion of bristle can not be concentrated strength on the roller seating space direction as a result, and the radius of motor is little and grow, so cause and can only install along the toothbrush parallel direction.The axle that is to say motor is to become an angle of 90 degrees with brush finish is vertical, just can't directly be connected and drive hairbrush with the brush dish and rotate.
Summary of the invention
The toothbrush of our this rotating band vibration, what use is flat motor, on the armature disc of casing inside, the installation of flat motor is on toothbrush in 3 millimeter, eccentric hammer to have big 4～6 times, the thickness of radius ratio bar shaped: the axle of motor is vertical mutually with the brush finish of toothbrush.We just can make two types toothbrush vibration, the rotating band vibration with the motor of this shape: first kind, we are installed in parallel in flat motor on the toothbrush face, have just obtained the toothbrush of band vibration.Second kind,, just can obtain the toothbrush that rotating band vibrates if we couple together the axle of motor with the toothbrush dish.Brush plate directly is connected with motor, is our proprietary unique technique, and is structurally simpler than the electric toothbrush of tradition rotation, greatly reduces manufacturing cost.The eccentric of flat electric machine is to be enclosed in the electric machine casing, can fix with the bristle injection moulding.And the eccentric of the bar shaped motor of documents, so outside motor casing, during injection moulding, reserve rotation space specially must for eccentric.
The toothbrush of this rotating band vibration has efficiently, the method that cleans the teeth healthy, that meet medical requirement.The direction of the direction of vibration of bar shaped motor and flat motor vibration is different. for toothbrush, the direction of flat motor vibration is reasonable more. because it can make bristles along roller seating space up and down high frequency motion to play the cleaning effect amplitude big, scrub effect and the effect that cleans the teeth just relatively good.In order to increase efficient and the amplitude that motor prolongs roller seating space direction up-down vibration, the present invention is in the design that connects head toothbrushes and brush holder, adopted the method for coordination of potent and mild therapies: along being gentle on the direction of roller seating space, be beneficial to bristles in bristles, strengthen the effect of cleaning along roller seating space high frequency motion up and down.And the vibration of toothbrush head is difficult for passing on the handle, then has certain rigidity on the brush finish vertical direction of head toothbrushes. favourable toothbrush moving in mouth.According to above principle, we with the union joint method for designing of head toothbrushes and brush holder are: it is relative narrower that union joint is parallel to the size of the flank of tooth, and union joint is wideer relatively perpendicular to the size of the flank of tooth.In order to increase the intensity of union joint, can add one section sheet metal at union joint.We also have following union joint in addition: 1, and adopt a pin to be connected between head toothbrushes and brush holder perpendicular to the toothbrush face, brush and brush holder can be swung in certain angle.2, adopt a sheet metal to be connected between head toothbrushes and brush holder perpendicular to the toothbrush face.3, adopt a row to be connected between head toothbrushes and brush holder perpendicular to one group of spring of toothbrush face.4, adopt a row to be connected between head toothbrushes and brush holder perpendicular to the post bar of toothbrush face.

The specific embodiment
The radius ratio bar shaped of the flat electric machine that we adopt big 4～6 times, eccentric is on armature disc, and amplitude is big, scrubs effect, and the effect that cleans the teeth is just relatively good.The installation of flat motor, the axle that can be motor is vertically to become an angle of 90 degrees mutually with the brush finish of toothbrush, so we can also make the toothbrush of rotation, we remove the eccentric hammer on the armature disc, allow the axle of motor directly be connected, just can drive the hairbrush rotation with the toothbrush card.Brush plate directly is connected with motor, is our proprietary unique technique, and is structurally simpler than the electric toothbrush of tradition rotation.Greatly reduce manufacturing cost.The eccentric of flat electric machine is to be enclosed in the electric machine casing, can fix with the bristle injection moulding.And the eccentric of the bar shaped motor of documents, so outside motor casing, during injection moulding, reserve rotation space specially must for eccentric.
