Description

Technical Field

[0001] This utility model relates to the field of toothbrush technology, specifically to an adjustable phototherapy electric toothbrush. Background Technology

[0002] A toothbrush is a cleaning product, a handle-type brush used to apply toothpaste to the brush and then repeatedly brush all parts of the teeth to maintain oral hygiene.

[0003] While toothbrushes are effective at cleaning surface stains, they fall short in providing deeper oral hygiene. For example, toothpaste or serums cannot effectively remove deep-seated yellowing. Similarly, conditions like periodontitis and gingivitis often require medication or topical anti-inflammatory solutions for treatment. While these traditional methods may alleviate some of the problems, the use of oral solutions, medications, and anti-inflammatory agents can inevitably enter the body and potentially harm health. Therefore, this practice is discouraged unless absolutely necessary.

[0004] Therefore, traditional toothbrushes, in addition to their basic cleaning function, cannot meet users' broader oral care needs.

[0005] To enhance the cleaning and care effect of toothbrushes, we incorporate light-curing LEDs, ultrasonic cleaning modules, and other components into the brush head. However, these functional components require electrical power to operate. While this isn't difficult to achieve in an all-in-one toothbrush, which can power these components through a built-in battery and internal wiring, it becomes much more challenging with the structure of an electric toothbrush. Firstly, the limited space within the toothbrush itself prevents the inclusion of bulky electrical components. Secondly, the technical challenges of wireless power supply and wireless signal control must be addressed. Currently, electric toothbrushes can wirelessly power the components by using a wireless power receiving coil and a power transmitting coil between the brush head and handle—two relatively independent components—to supply power from the battery built into the handle. However, the wireless signal... The technical problems of control remain unsolved. Commonly used wireless signal control technologies include Bluetooth and infrared. In addition to high cost and large size, Bluetooth technology also suffers from high power consumption. The built-in battery of an electric toothbrush cannot support Bluetooth use for extended periods. Infrared technology requires the receiver to be in direct contact with or reflect the transmission path to receive the signal, which is practically impossible given the structural characteristics of electric toothbrushes. As a result, current electric toothbrushes with added functional loads often only support a single operating mode. Moreover, this single operating mode is usually triggered directly when the internal circuitry of the toothbrush head is connected, and users cannot switch or adjust the functional mode according to their actual needs. Therefore, electric toothbrushes with added functional loads are currently quite impractical in actual use. Utility Model Content
