Touch-control flashing toothbrush

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.

What is claimed is: 
     
         1 . A touch-control flashing toothbrush comprising a hollow brush handle whose front end has a brush head and whose another end, which is opposite said brush head, has a light-permeable handle member; and

         2 . The touch-control flashing toothbrush according to  claim 1 , wherein said control circuit board further includes an audio element electrically connected with said control circuit, and wherein while said two electric-conduction contacts are touched simultaneously, said battery assembly is electrically connected with said control circuit and transmits voltage to said control circuit, whereafter said control circuit controls said audio element to provide music. 
     
     
         3 . The touch-control flashing toothbrush according to  claim 1 , wherein said light emitting element is a light emitting diode. 
     
     
         4 . The touch-control flashing toothbrush according to  claim 1 , wherein a suction disc is disposed at a rear end of said hollow brush handle for attaching said touch-control flashing toothbrush onto a plane. 
     
     
         5 . The touch-control flashing toothbrush according to  claim 1 , wherein a suction disc is disposed at a lateral surface of said hollow brush handle for attaching said touch-control flashing toothbrush onto a plane. 
     
     
         6 . The touch-control flashing toothbrush according to  claim 1 , wherein a rear end of said hollow brush handle has an opening, and wherein a cap is installed in said opening. 
     
     
         7 . The touch-control flashing toothbrush according to  claim 6 , wherein said cap has an inner thread and a positioning recess, and wherein said opening of said hollow brush handle has an outer thread, and wherein said outer thread has a positioning block, and wherein said cap is engaged with said hollow brush handle via screwing said outer thread into said inner thread until said positioning block is press-fit to said positioning recess. 
     
     
         8 . The touch-control flashing toothbrush according to  claim 1 , wherein said hollow brush handle has a side opening, and wherein a cover is installed in said side opening. 
     
     
         9 . The touch-control flashing toothbrush according to  claim 8 , wherein said cover has a press-fit member, and said side opening of said hollow brush handle has an assembly member, and wherein said cover is secured to said hollow brush handle through engagement of said press-fit member and said assembly member. 
     
     
         10 . The touch-control flashing toothbrush according to  claim 8 , wherein said cover is joined with said hollow brush handle by ultrasonic welding. 
     
     
         11 . The touch-control flashing toothbrush according to  claim 1 , wherein said battery assembly further includes a battery accommodation bay and at least one battery, and wherein said battery accommodation bay has a positive contact and a negative contact respectively at two ends thereof, and wherein said positive contact and said negative contact are respectively electrically connected with a positive electrode and a negative electrode of said battery to form a loop. 
     
     
         12 . The touch-control flashing toothbrush according to  claim 1 , wherein said light-permeable brush handle has a plurality of light-permeable patterns. 
     
     
         13 . The touch-control flashing toothbrush according to  claim 12 , wherein said light-permeable patterns are light-permeable patterned bumps, and wherein said hollow brush handle is sleeved by a brush handle protection shell having a plurality of patterned holes corresponding to said light-permeable patterned bumps, and wherein said light-permeable patterned bumps are expose to said patterned holes. 
     
     
         14 . The touch-control flashing toothbrush according to  claim 1 , wherein said two electric-conduction contacts are arranged at a rear end or a lateral surface of said hollow brush handle.
