Abstract: A disinfector accommodates a jetting nozzle and a hand detecting sensor disposed alongside of the jetting nozzle in a main body thereof. The jetting direction of the jetting nozzle coincides with the light emission direction of the hand detecting sensor. The jetting nozzle and the hand detecting sensor can be pivotally moved in unison. A malfunction which may occur due to the difference in the configurations of the bowl of the washstand and the kind of the material thereof can be solved by merely altering the light emission direction of the hand detecting sensor. Because the jetting direction of the jetting nozzle and the light emission direction of the hand detecting sensor are always coincident with each other, a user can use the jetting apparatus conveniently without feeling discomfort.

Abstract: An electric shaver comprising a shaver housing comprising a generally rectangular box-like casing and a head casing removably mounted on one end of the box-like casing; a finely perforated stationary shear foil replaceably mounted on the head casing; a reciprocable blade assembly positioned inside the head casing and outside the box-like casing and cooperable with the stationary shear foil to cut bristles entering the head casing through the perforations in the stationary shear foil; an electric drive motor accommodated within the box-like casing and having a drive shaft, said drive shaft having first and second ends opposite to each other and protruding outwards from the motor in opposite directions away from each other; means for connecting the first end of the drive shaft with the blade assembly to permit the blade assembly to undergo oscillation relative to the stationary shear foil; a photoelectric detector comprising a light emitting element and a photoelectric cell for providing an electric output sign
