Problems solved by technology

First, the additional mechanical linkage for the secondary movement has its own separate space requirement in addition to the space requirement of the primary movement, which increases the overall size of the brush head assembly and thus increases the The size will damage the swiping experience
Furthermore, the linkage operates in the frequency range of the brush head movement, which is noisy and also causes excessive wear due to the high acceleration of the parts
Still further, the additional linkage requires a large number of parts and delicate assembly work, which increases the cost of the toothbrush

Embodiment Construction

[0011] figure 1 An electric toothbrush 10 is shown. Toothbrush 10 includes a handle portion 12 and a head assembly 14 including a neck 15 and at its distal end a brush member 16 including a bristle base member 18 and a bristle region 20 . The brush head assembly is moved by a drive assembly in the handle, shown generally at 22, having a drive shaft 23 coupled to the brush head. The drive assembly is powered by a battery, usually rechargeable, and the toothbrush movement is controlled by a microprocessor 26 and an on-off switch 28 . As discussed above, the drive assembly is capable of producing various brush head assembly motions, including the bristle plate and the bristle region mounted thereon, including, inter alia, various oscillatory motions including rotational, axial or Swipe.

[0012] In the present invention, the brush head assembly 16 includes a multi-motion brush member, in particular a brush member with two different motions. As described above, one movement (i...

Abstract

A brush head (14), including a neck (15) connected at its proximal end to a handle portion (12) of an electric toothbrush (10). At the distal end of the neck is a brush member (16, 28) comprising a bristle base (18, 34) and a bristle field (20, 36) mounted thereon. An eccentric (30) mounted for the rotating action on the bristle base is located in the middle of the bristle field. An eccentric bristle area (38) is mounted on the eccentric wheel. The movement of the brush member produced by the toothbrush drive assembly results in rotational movement of the eccentric wheel and the eccentric bristle field mounted thereon, which produces an additional oral cleaning action.

Description

technical field [0001] The present invention generally relates to electric toothbrushes having a brush member having an oscillating motion for cleaning teeth, and more particularly includes such a brush member having multiple synchronized movements provided by different parts of the brush member. Background technique [0002] All electric toothbrushes include a drive assembly that drives the movement of the brush parts designed to clean the teeth through the movement of the bristles. This motion can vary and includes, among others, rotational and axial motions, as well as sweeping motions. Typically, the most efficient motion is oscillatory, involving back and forth movement of the brush member through a selected angle. While most electric toothbrushes have only a single motion, some electric toothbrushes have multiple motions, usually two, typically a primary motion and a secondary motion accomplished by two separate parts of the brush member. [0003] In many cases, the ...
