Problems solved by technology

There must be enough clearance so that the two parts are easily coupled and separated on all parts made, but if the tolerance is too large, there will be rattling during use while the drive shaft transmits the drive to the brush head, making the cleaning action possible
This noise may detract from the user experience of using the toothbrush

Abstract

There is provided an attachment structure for a personal care appliance, the attachment structure comprising a body having a proximal end and a distal end, wherein the proximal end has a coupling receptacle that is for coupling to a drive shaft of a handle of the personal care appliance; and wherein the coupling receptacle has one or more portions of shear-thickening material on an interior surface thereof. A corresponding personal care appliance and method of securing an attachment structure to a handle of a personal care device are also provided.

Description

technical field [0001] The present embodiments relate generally to personal care appliances, such as electric toothbrushes, and more particularly, to attachment structures for personal care appliances, such as toothbrush heads. Background technique [0002] In connection with oral hygiene, the main rationale for using a toothbrush (eg, an electric toothbrush) to remove plaque is to obtain sufficient bristle tip pressure on the toothbrush head. Optimizing the power transfer from the motor to the brush head is one mechanism to achieve this. Other types of personal care appliances require a similar goal of maximizing power transfer efficiency. [0003] Typically, the toothbrush head must be coupled to the toothbrush handle by a mechanism that allows easy removal and replacement while preventing the toothbrush head from falling out during use. However, the toothbrush head must not be loose, otherwise it will rattle and amplify vibrations that affect the user experience. This ...
