Embodiment Construction

[0019] Referring now to the accompanying drawings, figure 1 Components of an electric toothbrush 10 according to one embodiment of the present invention are shown, including systems to reduce mechanical shock and dampen vibrations.

[0020] Most of the components of electric toothbrush 10 are housed within an elongated housing 20, which is preferably sized to fit comfortably in a human hand. Preferably made of rigid and lightweight plastic, the housing 20 protects and seals internal components from impact and water ingress. The housing 20 includes an opening at the distal end, ie, the end showing the shaft distal end 63 , and an opening at the proximal end, ie, the end showing the end cap 120 .

[0021] Disposed in the housing 20 is a frame 40 . Frame 40 is configured to hold most of the remaining system components, each of which is described in detail below. Frame 40 may also be constructed of lightweight rigid or semi-rigid plastic.

[0022] The frame 40 is provided with...

Abstract

A multi-function charging coil bobbin (90) for a power toothbrush (10) configured to improve the durability of the toothbrush and to simplify the assembly process. The coil bobbin (90) provides a bridge spring (98) for tolerance mitigation and shock protection, and also provides a coil winding surface (92) such that the bobbin (90) can be wound prior to final assembly. The coil bobbin (90) may be unitary in structure for low cost.

Description

technical field [0001] This application claims the benefit of, and describes the relationship between, the following applications: of which this application claims priority to U.S. Provisional Patent Application Serial No. 61 / 980230, filed April 16, 2014, in its entirety The contents are incorporated herein by reference. [0002] Aspects of the present invention generally relate to electrically powered toothbrushes. More specifically, the present invention relates to toothbrush features that increase durability and control vibrations transmitted to the user through the handle of the toothbrush. Background technique [0003] Electric toothbrushes are generally known and include a wide variety of designs and physical configurations. Many electric toothbrushes have a rotary type of motion. Some have 360° armature rotation capability, but due to design layouts produce oscillatory motion that is limited to a specific range of motion, ie a selected arc portion of 360°, in order...
