Abstract: A touch-control flashing toothbrush comprises a hollow brush handle and a control circuit board. The hollow brush handle has a brush head at one end and a light-permeable handle member at another end. The control circuit board is arranged inside the hollow brush handle and includes a control circuit electrically connected with a light emitting element, two electric-conduction contacts, and a battery assembly. The battery assembly supplies power to the other elements. The electric-conduction contacts are exposed on the surface of the hollow brush handle. Once two electric-conduction contacts are touched simultaneously, voltage of the battery assembly is conducted to the control circuit. Then, the control circuit controls the light emitting element to emit light projecting to exterior through the light-permeable handle member. The touch-control flashing toothbrush is triggered to emit light by touch, interesting children and encouraging them to keep oral health.

Abstract: In a lighting toothbrush structure, a front end of a hollow brush handle connects with a brush head. The hollow brush handle is provided with a first transparent patterned layer and a cavity. At least one slide track is arranged on an inside wall of the hollow brush handle. A lighting circuit board is arranged in the hollow brush handle by using the slide track. A switch is protruded from and mounted in the cavity, conveniently pressed by a user. The switch and the brush set belong to an identical side. The switch controls a lighting element to emit light, and the light is projected outside through the first transparent patterned layer. An inner thread of a tail cover is screwed to an outer thread of a rear end of the hollow brush handle to assemble the lighting toothbrush structure with a lighting function.

Abstract: A transmission device of electric toothbrush includes a handle assembly, a brush assembly, and a transmission mechanism. The handle assembly has a shaft coupled to the brush assembly so that the brush assembly is rotatable about the handle assembly. The transmission mechanism is mounted on the handle assembly and comprising a coupling member, a transmission shaft, the coupling member being coupled to the brush assembly so as to move together, a groove on the coupling member, and a transmission rod at one bent end of the transmission shaft being engaged within the groove. Hence, the brush assembly is operative to rotate and vibrate.

Abstract: A electric toothbrush structure comprises a block handle, power transmission device and blockhead; the power transmission device at least comprises a electric motor and transmission device, and the transmission consists of a outer gear, inner gear and connecting rod, the outer gear is connected to the shaft of the electric motor, and meshes with it inside the inner gear, the connecting rod is connected to the shaft of the inner gear, and a crooked shaft is disposed at the position of the connecting rod corresponding to the blockhead. The blockhead is connected to the block handle, it comprises a blockhead tube and circular head, the blockhead is used to accept the connecting rod, and circular head is pivoted to the front end of the blockhead, a groove, which is disposed at the bottom end of the circular head, is used to accept and connect with the crooked shaft of the connecting rod and driven by it to rotate left and right.

Abstract: A male type USB (universal serial bus) connector includes a substantially rectangular connector body, a cable connected to the connector body and extended out of a hole at a rear side wall of the connector body, two symmetrical insulative shells fastened together and covered on the rear side wall and two opposite lateral side walls of the connector body and a part of the cable to secure the cable in place, and an insulative cap fastened to the connector body and the insulative shells at a front side, the cap having a center coupling hole, which receives a front side wall of the connector body, and a backward coupling flange coupled to the insulative shells.
