[0001] This utility model relates to the field of oral care equipment technology, and in particular to a two-in-one water flosser and electric toothbrush. Background Technology

[0002] With increasing awareness of oral health, water flossers and electric toothbrushes have become common oral care tools. Water flossers use high-pressure water jets to clean areas that are difficult for toothbrushes to reach, such as between teeth and in the gum line, while electric toothbrushes achieve efficient brushing through high-frequency vibration or oscillation. Using both together can significantly improve oral cleaning results.

[0003] However, existing water flossers and electric toothbrushes are mostly separate products, which have the following shortcomings: First, it is inconvenient to carry and use. Users need to carry two different devices and corresponding chargers and accessories when they go out, which takes up luggage space. When using the toothbrush device to brush their teeth, they also need to use a separate toothbrush cup. Secondly, the cost of use is high. Purchasing two separate devices requires paying more, and separate charging and maintenance also increase the complexity of use. Third, the integration of functions is low, making it impossible to quickly switch between brushing and flossing functions on the same device, which affects the efficiency of oral care. Therefore, there is an urgent need to design a device that integrates the functions of a water flosser and an electric toothbrush to solve the above problems. Summary of the Invention
