The invention discloses an automatic
toilet cleaning
brush, which comprises a
brush handle, a
brush handle cover, a
toilet cleaner container, a brush head, bristles, a button for controlling spraying-out of a
cleaning agent, a button for controlling the brush head to rotate, a battery
jar, a positive and negative-rotating motor for controlling spraying-out of the
cleaning agent, a shaft
coupling,a positive and negative-rotating motor rotating shaft, a gear, a gear rack, a
piston rod, a
piston, a motor for controlling the brush head to rotate, a brush head rotating shaft, a power outlet, a battery, a bearing and hair holes; the
toilet brush is characterized in that rotation of the gear is turned into moving of the
piston under the driving of the gear rack by virtue of a gear-gear rack mechanism; the piston moves forwards when the positive and negative-rotating motor for controlling spraying-out of the
cleaning agent rotates positively, so that pressure in an accommodating cavity is changed, and the toilet cleaner flows out from the hair holes; the piston moves backwards and is reset when the positive and negative-rotating motor for controlling spraying-out of the cleaning agent rotates negatively; the motor for controlling rotation of the brush head is connected to the brush
head rotation shaft, so that the brush head can be conveniently controlled to rotate; and the brush headis detachable. The automatic toilet cleaning brush provided by the invention has the advantages that the toilet cleaner and the brush are integrated into a whole structure and functions of automatically spraying out the toilet cleaner and automatically conducting brushing are achieved, so that toilets can be cleaned more conveniently and effectively.
