    • PROBLEM TO BE SOLVED: To provide a comfortable and hygienic toothpaste as conventional toothbrush (including an electric toothbrush) and related technologies have such structural and hygienic problems wherein a hand of a user is stained with the toothpaste while brushing teeth and wherein the toothpaste is scattered in the periphery.SOLUTION: By forming the rotary sloping toothpaste pan in the toothbrush (including the electric toothbrush), the direction of dripping of a toothpaste liquid can be controlled. Further, as the sloping pan can be rotated at 360 degrees, the user's hand or the periphery is not stained with the toothpaste liquid if teeth are brushed with the toothbrush held at right angles or close to right angles.
    • 要解决的问题:提供一种舒适和卫生的牙膏作为常规牙刷(包括电动牙刷),并且相关技术具有这样的结构和卫生问题,其中使用者的手在刷牙时被牙膏染色,并且其中牙膏分散 在外围。解决方案:通过在牙刷(包括电动牙刷)中形成旋转倾斜牙膏盘,可以控制牙膏液滴的方向。 此外,当倾斜盘可以360度旋转时,如果用牙刷刷直角或接近直角刷牙,用户的手或周边不会被牙膏液污染。
