The brush head of the toothbrush has filaments that are pointed at one end and led through clearances in the bristle carrier. These filaments have a length of about 10-20 mm. The tips of the pointed filaments produce a height profile other than that of a plane and the ends of the pointed filaments that are remote from the tips are melted.

The double action push broom of the present invention includes a dynamic double action dual brush head and a broom handle. The dynamic double action dual brush head includes two brush heads rotatably attached to a brush head base, allowing the brush heads to independently rotate about the axis in which it is rotatably attached to the brush head base. A mechanical device capable of storing and releasing energy is connected between the two brush heads, which is rigidly attached to the brush head base. The double action push broom stores kinetic energy in the form of potential energy in the mechanical energy storage device of the dynamic double action dual brush head during the sweeping stroke of the double action push broom. At the end of the sweeping stroke, the stored potential energy is converted into kinetic energy and rotates the dual brush, thereby providing an additional sweeping motion.

The present invention published a method of mechanically operated scouring abrasion and a mechanically operated scouring abrasion head which transmits the pushing force to the top of the scouring abrasion object to scour and abrade the surface. The mechanically operated scouring abrasion head comprises a scouring abrasion object, scouring abrasion head, supporting position and pushing position. The scouring abrasion object is connected with the scouring abrasion head. The supporting position is on the scouring abrasion head wherein a ratio of the scouring and abrasion force is adjusted by adjusting a position and work pattern of the supporting position to generate scouring and abrasion momentum of different ratios and swing the scouring abrasion object back and forth downward. The present invention deals with the stains in the irregular concaves, which rapidly clean the convex or the stubborn stains on the regular plane which can't be achieved by the conventional technology.

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.

To provide a rotary toothbrush including a ratchet mechanism that is capable of rotating if exceeding a predetermined frictional resistance during brushing forward movement and incapable of rotating during backward movement by the interaction between a semicircular protrusion portion on the bottom of a guide plate installed on the inside of a pair of right and left bearing plates of a handle part and a pawl formed on the vertex of a polygonal rotary shaft to which a brush member is attached, and also that, by installing the protrusion portion and the pawl in an opposite direction, becomes incapable of rotating during the forward movement and capable of rotating during the backward movement.

A toothbrush apparatus and system designed to simplify the cleaning of all surfaces of the teeth, by simplifying the brushing process to a single motion performed on the top and bottom rows of teeth, and thereby by reducing the cognitive difficulty of learning the brushing task. Simplification is accomplished by using a unique brush head that wraps around the teeth to cover the inside, top, and outer surface of the teeth at once, while a pivot mechanism with a restorative force component attaches the brush head to the brush stem, and allows the brush head to rotate about itself. These two elements combine to allow the brush head to glide around the teeth like a train on a track as the brush is moved around the mouth.
