<p>PURPOSE:To more simply inspect the effectiveness of a contained electric power source without increasing cost by connecting an electric power source voltage tester to be detachable on the holder, equipping it at a specified position in an ion tooth brush. CONSTITUTION:A tester 38 is coaxially and detachably connected at the end of the holder 10 in order to inspect the effectiveness of cells 18. The tester 38 serves as a part of the holder 10 during connection with the holder 10 and it can be used during brushing, kept and carried in this state. When it is necessary to inspect the effectiveness of the cells 18, the tester 38 is removed from the holder 10 and the contact terminal 54 and 56 of the tester 38 are brought into contact with the axis 16 and the end plate 20 respectively. While the cells 18 are available, the current flows in a light emitting diode 40 of a light emitting substance 46 and the luminescence of the light emitting diode 40 can be confirmed from the winder 52 of the lid 50 of the tester 38.</p> |
