Electric steam cleaner

An electric cleaner, comprising:

• a steam delivery system;
• a cleaning head;
• and a drive assembly, wherein said steam delivery system directs high-temperature steam to said cleaning head, so as to form a high-temperature steam environment, wherein said drive assembly electrically drives said cleaning head to move within said high-temperature steam environment;
• wherein said drive assembly comprises a rotating motor and an eccentric transmission assembly, wherein said rotating motor is powered by electrical energy to generate rotational force around a first axis, wherein said eccentric transmission assembly is driven by the rotational force from said rotating motor, thereby rotating said cleaning head around a second axis, wherein the first axis and the second axis maintain a predetermined distance while remaining parallel to each other;
• wherein said eccentric transmission assembly comprises a torque-enhancing assembly and a passive rotary body, wherein said torque-enhancing assembly is driven by said rotating motor to rotate around the first axis, wherein said passive rotary body engages with said torque-enhancing assembly and rotates around the second axis under the drive of said torque-enhancing assembly, thereby driving said cleaning head to rotate around the second axis;
• wherein said torque-enhancing assembly comprises a first sun gear, a first planetary gear set, an internal gear ring, a first turntable, a second sun gear, a second planetary gear set, and a second turntable, wherein said rotating motor comprises a motor body and a motor output shaft extending from said motor body, wherein said motor output shaft defines the first axis, wherein said motor output shaft is driven to rotate around the first axis, wherein said first sun gear is fixedly connected to said motor output shaft, rotating with said motor output shaft to drive said first planetary gear set to rotate around said first sun gear, wherein said internal ring gear engages with said first planetary gear set to guide the rotation of said first planetary gear set, wherein movement of said first planetary gear set drives said first turntable to rotate around said first shaft, wherein rotation of said first turntable synchronously drives said second sun gear to rotate, and further drives said second planetary gear set to rotate around said second sun gear, wherein said internal ring gear engages with said second planetary gear set to limit the rotation of said second planetary gear set, wherein movement of said second planetary gear set drives said second turntable to rotate around said first shaft, wherein said second turntable engages with a passive rotary body, so as to drive said passive rotary body to rotate around the second axis and further drive said cleaning head to rotate around the second axis.
