Abstract: A toothbrush having a physiological sensing function, comprising a grip part, a head part, and a sensing module. The grip part has an inner space as well as a top end and a tail end opposite to each other in a length direction. The head part is provided at the top end of the grip part. The grip part is further provided with a sensing region. The sensing module is provided in the inner space of the grip part and disposed corresponding to the sensing region. The sensing module executes a physiological sensing function in the sensing region, and generates physiological sensing information. When a user holds the toothbrush to brush teeth, a finger pulp or palm of the user presses on the sensing region, and thus the sensing module can execute the physiological sensing function by means of the sensing region and generate physiological sensing information, so that the user can understand his/her own health information more comprehensively.

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 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.

Abstract: The invention is related to a toothbrush head which comprises a head base, a head frame, and bristles. The head base comprises a front end, a back end, multiple strip-substrates, and multiple junctions. The multiple strip-substrates are aligned between the front end and the back end and each two adjacent strip-substrates link with each other with each of the multiple junctions, and each of the multiple strip-substrates comprises multiple sockets for inserting the bristles. The head frame comprises a bottom surface and multiple accommodating spaces for accommodating the head base. The toothbrush head allows the bristles to be bent into the arc shape when touching the teeth, so as to increase touching areas between the brushes and the teeth for enhancing cleaning effect and decreasing risks of causing caries.

Abstract: An interdental brush has a hard body, an encapsulation layer and a plurality of soft and elastic bristles. The hard body takes a straight form and has a grip portion and a slender bristle portion. The hard body is sheathed by a soft and elastic material to form the encapsulation layer by means of insert molding. A grip is formed by sheathing the grip portion with the encapsulation layer to enhance holding comfort. The plural elastic bristles aligned in a radial fashion are formed on a surface of the encapsulation layer corresponding to the bristle portion. Given the foregoing interdental brush structure, the elastic bristles on the bristle portion can be deeply slid in between teeth for cleaning. The soft and elastic nature of the bristles ensures gums are not injured during cleaning.

Abstract: The present invention relates to a toothbrush having a bristle support head having a plurality of bristles densely implanted thereon and a brushing surface formed by ends of the bristles. The contact area between the bristle support head and teeth can be increased by virtue of the brushing surface. Reciprocal motion of the bristle support head maintains contact between the bristles and teeth so removes contaminants from inter-tooth spaces effectively and with improved efficiency.
