Cleaning tool and cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices, particularly cordless/handheld vacuum cleaners, require multiple cleaning heads for different scenarios, which complicates effective cleaning and can lead to inefficiencies and difficulties in handling various surfaces.
Innovation Solution
A cleaning tool with a suction pipe, brush head outer and inner casings, a motor casing, and a bottom plate with raised portions for movement, along with a driving member and brush strip, designed to rotate and lock securely, ensuring effective cleaning without compromising suction efficiency or requiring tools for assembly/disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cleaning heads are used for different cleaning scenarios, then cleaning effectiveness for various surfaces is improved, but device complexity and handling difficulty increase
Solution Approach 1:
The cleaning head is designed with a universal structure that can adapt to different cleaning scenarios through relative rotation between the brush head inner casing and outer casing. The bottom plate with raised portions can be positioned at different locations to suit different surface types, allowing one cleaning head to perform multiple functions rather than requiring separate heads for each scenario.
Solution Approach 2:
The cleaning head incorporates dynamic adjustability through the relative rotation mechanism between the inner and outer casings. This allows the bottom plate position to be changed during use, enabling the same cleaning head to adapt to different cleaning requirements dynamically rather than being fixed for a single purpose.
2Adaptability or versatility
If the bottom plate is rotatably connected to allow position adjustment, then adaptability to different surfaces is improved, but reliability of connection may deteriorate
Solution Approach 1:
The driving member is designed with a limiting function that prevents over-rotation of the bottom plate. The limiting structure is built into the connection mechanism itself, providing built-in protection against excessive rotation that could compromise connection reliability, while still allowing the necessary range of motion for adaptability.
3Ease of operation
If the brush head inner casing is made detachable via relative rotation, then ease of assembly and disassembly is improved, but device complexity increases
Solution Approach 1:
The cleaning head is divided into separable components - the brush head inner casing can be detached from the outer casing through relative rotation. This segmentation allows easy assembly and disassembly for maintenance or replacement while keeping the overall structure relatively simple through the use of a straightforward rotational connection mechanism.

AI summary
A cleaning tool, including a suction pipe, a brush head outer casing, a motor casing, and a brush head. The cleaning tool further includes: a brush head inner casing, which is relatively rotatably provided in the brush head outer casing and forms an accommodation cavity of the brush head; and a bottom plate, which is integrally formed with the brush head inner casing and forms a cleaning contact surface of the cleaning tool. The bottom plate includes a front raised portion and a rear raised portion.
