Electric Mop Head Component Layout for Suspended Stability and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric mop heads suffer from instability and poor sealing due to improper component positioning, leading to tilting and swaying during use, and are prone to water ingress, affecting their service life.
Innovation Solution
The motor and battery are positioned on the same axis parallel to the central axis, with the battery behind the hinge base, ensuring the center of gravity is aligned, and are hermetically sealed within the base using an inner cover and sealing ring, while symmetrically arranged dusting brushes and dust boxes enhance stability and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the motor, battery, and hinge base are mounted without considering their influence on the center of gravity position, then the component layout is simple and easy to manufacture, but the overall center of gravity deviates from the central axis, causing the mop head to sway and tilt forward when suspended
Solution Approach 1:
The patent applies asymmetry by strategically positioning components (motor, battery, hinge base) at specific locations that are not symmetrically distributed but are optimized to achieve the desired center of gravity position on the central axis. The hinge base is positioned at the rear, the motor at the front, and the battery in the middle, creating an asymmetric layout that balances the overall center of gravity.
Solution Approach 2:
The patent changes the positional parameters of components to optimize the center of gravity location. By adjusting the mounting positions of the motor, battery, and hinge base along the longitudinal axis, the design achieves the target center of gravity position on the central axis, preventing unwanted tilting and swaying.
2Reliability
If the motor and battery are only closed in the base through the housing, then the structure is simple, but the overall sealing performance is poor, allowing water to enter and damage components
Solution Approach 1:
The patent segments the sealing structure into multiple components: the housing forms the outer seal, the base provides a separate sealing layer, and additional sealing elements (such as gaskets or seals) are introduced at critical interfaces. This multi-layer segmented sealing approach enhances waterproofing while maintaining structural clarity.
Solution Approach 2:
The patent introduces intermediary sealing elements (such as sealing rings, gaskets, or membranes) between the housing, base, and internal components. These intermediary elements act as mediators that prevent water ingress at critical interfaces without requiring complete redesign of the overall structure.

AI summary
The present invention discloses an electric mop head, including a base, a housing, a motor, a battery, a dusting brush, a dust box, and the like. A hinge base on the housing is arranged on a central axis of the electric mop head, the motor is arranged in front of the battery, and centers of gravity of the motor and the battery are both arranged on a same axis. The axis and the central axis of the electric mop head are parallel to each other and on a same vertical plane. The battery is located on a rear side of the hinge base. In this way, the battery drives the overall center of gravity of the electric mop head to move backward, and the overall center of gravity is also on the central axis. Therefore, when the electric mop head is brought into a suspended state as a result of lifting a mop handle, the electric mop head is not only maintained in a stable state, but also maintained in a position in which the electric mop head is tilted about the hinge base such that a rear end is lower than a front end to drive the dust inlet on the front part of the dust box to tilt upward, thereby preventing dust and hair in the dust box from accidentally falling from the dust inlet. In addition, the motor and the battery are both hermetically sealed through an inner cover on the mounting groove of the base through snap fit connection, to reduce damage to the motor or the battery caused by accidental water inflow and avoid affecting a service life of the electric mop head.
