Embodiment Construction

[0021] refer to figure 1 and figure 2 , an electric toothbrush 10 includes a handle 12 and a brush head 14 removably mounted to the handle. exist figure 2 The drive shaft 16, most clearly seen in , extends from the handle 12 into the brush head. Annular gap 18 is defined by the gap separating handle 12 from brush head 14 . The drive shaft 16 is driven rotationally or through a selected vibration angle by a drive mechanism 20 housed in the handle 12 . A brush member 22 is provided at the distal end (upper end) 23 of the brush head for cleaning teeth.

[0022] The replaceable brush head 14 includes a housing 24 that defines an interior cavity 26 that extends into the brush head from a proximal (bottom) end 28 of the brush head. The drive shaft 16 extends into and securely engages a coupling member 30 which extends from the proximal end 28 of the brushhead housing into the cavity 26 . An annular seal 32 is positioned around the drive shaft 16 , inside the coupling member ...

Abstract

A replaceable brush head (14) for a toothbrush (10) includes a housing (24) which defines an interior cavity (26). A brush member (22) is located at a distal end (23) of the housing. A receptacle (40)is located at a proximal end (28) of the housing. The receptacle holds a material (44) that removes an essential nutrient for growth of mold from liquid (36) when the liquid contacts the receptacle.

Description

Background technique [0001] The following relates to the field of dental care and related fields, and more particularly to an apparatus and method for inhibiting the growth of mold on a toothbrush. [0002] Microorganisms such as molds survive on the nutrients that surround them. Depending on the ecosystem, one of these nutrients may be growth-limiting, meaning that an organism's ability to reproduce is largely dependent on an adequate supply of the nutrient. Usually nitrogen is the limiting nutrient, although phosphorus is in some environments. [0003] Toothbrushes can be susceptible to mold growth due to nutrients in food that are brushed off the teeth, ingredients in many toothpastes such as phosphates, and frequent abundant supplies of water. Toothbrushes (and electric toothbrushes in particular) can include crevices where mold can grow, such as the gap between the brush head and the handle in electric toothbrushes. The seals in the gap are designed to keep water out o...
