Description:Field of the Invention


The present disclosure relates to electric toothbrush systems. Particularly, the present disclosure relates to dual-axis rotating electric toothbrushes with real-time oral health monitoring capabilities for enhanced oral hygiene and health tracking.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Electric toothbrushes are widely used as an alternative to traditional manual toothbrushes for improving dental hygiene. Such electric toothbrushes often utilize rotating brush heads that enable more effective cleaning compared to conventional toothbrushes. Generally, single-axis rotating electric toothbrushes are common, wherein the brush head rotates around a single axis to clean the teeth. The rotation of such brush heads is typically driven by a motor assembly housed within a handle portion of the toothbrush. Single-axis rotating toothbrushes are often employed for removing plaque, bacteria, and debris from the surface of the teeth, improving oral health, and minimizing the risk of gum disease. However, the cleaning effectiveness of single-axis rotating toothbrushes remains limited to the area directly in contact with the brush head due to the unidirectional movement of the bristles.
Moreover, to improve the overall cleaning performance, some systems integrate oscillating mechanisms into the rotating brush heads. Oscillating toothbrush systems employ oscillating movements along with rotating movements to achieve better plaque removal. The oscillating brush head moves back and forth while also rotating to enhance the contact between the bristles and the teeth. Such oscillating mechanisms enable improved cleaning performance compared to solely rotating brush heads by increasing the number of contact points and cleaning angles during brushing. However, oscillating toothbrush systems are typically associated with increased mechanical complexity and higher manufacturing costs. Additionally, the oscillating action often generates greater vibrations, which may result in user discomfort during brushing.
In some toothbrush systems, a combination of rotating and oscillating mechanisms is utilized to improve overall performance. These systems generally employ rotating brush heads that also oscillate at different angles to enhance the cleaning range. However, such systems still rotate or oscillate around a single axis. As a result, such systems are associated with limitations in terms of cleaning efficacy when attempting to clean hard-to-reach areas of the mouth, including areas between teeth or along the gumline. Furthermore, toothbrushes utilizing single-axis rotation mechanisms are frequently unable to provide uniform cleaning performance due to the restricted range of motion of the bristles.
Another approach is the use of reciprocating toothbrush systems. In reciprocating toothbrushes, the brush head moves in a straight line or back-and-forth motion, rather than rotating. Such systems offer an alternative method for improving cleaning performance by allowing the bristles to make contact with more surface area. However, reciprocating toothbrush systems are also associated with certain limitations. The linear motion of the brush head may fail to reach all the surfaces of the teeth effectively, particularly in the areas where teeth are closely spaced. Furthermore, reciprocating motion alone often results in reduced flexibility of the bristle movement, which may further limit the brushing efficiency.
The existing systems mentioned above face challenges in providing adequate cleaning coverage and effective reach to all areas of the mouth, particularly areas between teeth and along the gumline. Single-axis rotation or reciprocating systems are unable to adequately address these challenges due to the inherent limitations of unidirectional motion, restricted range of bristle movement, and reduced flexibility of the cleaning mechanism. Therefore, there remains a demand for improved systems that overcome the above-discussed drawbacks by enhancing the overall cleaning coverage, providing more flexibility in bristle movement, and increasing the range of motion of the brush head to enable cleaning of hard-to-reach areas.
In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and techniques for improving the effectiveness of electric toothbrushes by enabling enhanced cleaning coverage and flexibility of bristle movement.
