[0034] See also Figures 1 to 4The embodiment of the present application discloses an electric cleaning brush, comprising a cleaning brush head 1, a brush handle 2 and a battery 3, wherein the cleaning brush head 1 is connected to the front end of the brush handle 2, and the battery 3 is connected to the rear end of the brush handle 2 and is used to power the cleaning brush head 1, wherein the cleaning brush head 1 comprises a housing 11, a driving motor 12, a transmission assembly 13 and two cleaning brush discs 14, wherein the two cleaning brush discs 14 are rotatably connected to the front side of the housing 11, wherein a mounting cavity 111 is provided in the housing 11, wherein the driving motor 12 and the transmission assembly 13 are both mounted in the mounting cavity 111, wherein a driving shaft 121 of the driving motor 12 is transmission-connected to an input end 131 of the transmission assembly 13, and an output end 132 of the transmission assembly 13 is transmission-connected to the two cleaning brush discs 14, so as to make the two cleaning brush discs 14 rotate in opposite directions, i.e., the two cleaning brush discs 14 rotate in opposite directions. The driving motor 12 is electrically connected to the battery 3.

[0035] Specifically, in order to improve transmission accuracy and stability, the transmission assembly 13 includes a driving gear 133, a first intermediate gear 134, a second intermediate gear 135, a first driven gear 136 and a second driven gear 137; the driving gear 133 is fixedly connected to the driving shaft 121 of the driving motor 12, the first intermediate gear 134 is meshed with the driving gear 133 for transmission, the first driven gear 136 is meshed with the first intermediate gear 134 for transmission, and the first driven gear 136 is connected to one of the cleaning brush discs 14 through a first rotating shaft 138; the second intermediate gear 135 is meshed with the first intermediate gear 134 for transmission, the second driven gear 137 is meshed with the second intermediate gear 135 for transmission, and the second driven gear 137 is connected to the other cleaning brush disc 14 through a second rotating shaft 139.

[0036] As can be known from the above, the entire electric cleaning brush is composed of a cleaning brush head 1, a brush handle 2 and a battery 3. The battery 3 is powered by a driving motor 12. The driving motor 12 drives a driving gear 133 fixed on the driving shaft 121 through a driving shaft 121, thereby driving a first intermediate gear 134 meshed with the driving gear 133.
