Abstract: A detecting machine for a yield rate of bristles of a toothbrush and a detecting method for the bristles are provided. The detecting machine includes a power device and two rotating units, and the two rotating units are rotatably mounted on a side surface of the power unit. The two rotating units are disposed parallel to each other. When in a rotating condition, the two rotating units rotate in opposite rotating directions. When a manufacturer horizontally disposes a toothbrush between the two rotating units, the surfaces of the two rotating units may compress the bristles and pull the bristles toward a direction away from the toothbrush. Therefore the manufacturer can inspect whether the bristles are firmly mounted on the toothbrush.

Abstract: A toothbrush head comprises a head base and a head frame framing the head base. The head base comprises a substrate with multiple sockets for inserting bristles. The substrate has an outer frame, a central component, and two lateral components. The outer frame comprises a space, a front inner wall, a back inner wall, and two lateral inner walls. The central component is positioned in the space of the outer frame and links to the front inner wall and the back inner wall thereof. Each of the two lateral components is positioned between the central component and each of the two lateral inner walls and links to each of the two lateral inner walls with junctions, respectively, allowing the two lateral components to be rotatable. The toothbrush head helps users to brush the teeth with Bass method without injuring the gingiva, and keeps the toothbrush clean after brushing the teeth.

Abstract: A toothbrush head has a body, multiple cavities, and multiple through holes. The body is an elongated bar and further has a top surface and a bottom surface. The multiple cavities are recessed into the top surface at spaced intervals. Multiple bristle units are respectively mounted in the multiple cavities. The multiple through holes are formed on the body. The multiple through holes are adjacent to the multiple cavities. The multiple through holes are defined through the top surface and the bottom surface directly. The multiple through holes are utilized to remove the moisture and the food residues easily. Furthermore, the multiple through holes may also increase air convection around the toothbrush head. The toothbrush head may be air-dried fast and avoid bacteria breeding effectively.

Abstract: A toothbrush head includes a main body composed of multiple cylinder bodies, made of rigid material, and mounted by multiple bristles on the surface of each of the multiple cylinder bodies. The multiple cylinder bodies are separate or are connected to each other by connecting strips. A soft cladding layer is formed on an exterior of each of the multiple cylinder bodies. The toothbrush head can be connected to a brush holder to form a toothbrush. As each of the multiple cylinder bodies having multiple bristles can oscillate in different directions, the toothbrush can efficiently clean the teeth surface and crevices in different directions and facilitate convenience of cleaning.
