Reciprocating Dust Scraping Assembly for Filter Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices face issues with filter clogging due to dust accumulation, which reduces suction performance and is difficult to clean, often leading to compromised sealing and reduced service life.
Innovation Solution
A cleaning device equipped with a dust scraping assembly that moves reciprocally along the filter to scrape off dust, combined with a mechanism to automatically open the dust cup cover for easy cleaning, enhancing filter cleaning convenience and effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is cleaned by disassembling the dust cup housing and taking out the filter, then the filter can be cleaned, but the sealing performance between components is reduced and service life is shortened
Solution Approach 1:
The dust cup housing is equipped with an integrated cleaning mechanism that includes a cleaning brush and water supply system, enabling the filter to clean itself without disassembly. The cleaning brush rotates to scrub the filter surface while water is supplied to rinse away dust, eliminating the need for manual disassembly and reassembly operations that compromise sealing performance.
Solution Approach 2:
The cleaning mechanism integrates multiple functions into the dust cup housing structure: the cleaning brush is mounted within the housing, water supply channels are built into the housing walls, and the drive mechanism is incorporated into the housing assembly. This merging of cleaning components with the housing structure enables filter cleaning without requiring separation of the housing parts.
2Reliability
If the dust cup cover is kept closed to maintain sealing, then sealing performance is preserved, but cleaning access to the filter is blocked
Solution Approach 1:
The cleaning mechanism operates entirely within the closed dust cup housing, with the cleaning brush and water supply system accessible through the closed cover. The filter cleans itself through the integrated mechanism without requiring the cover to be opened, maintaining sealing performance while enabling cleaning functionality.
Solution Approach 2:
The cleaning brush acts as an intermediary tool that reaches the filter through the closed dust cup housing structure. Water supply channels serve as intermediaries to deliver cleaning fluid to the filter without opening the cover. These intermediary elements enable cleaning access while maintaining the closed, sealed state of the dust cup.

AI summary
A cleaning device (100) includes a main body portion (10), a dust cup (11), and a dust scraping assembly. The main body portion (10) includes a first filter (12). The dust cup includes a cup body (111) and a cup cover (112). The cup body (111) is connected to the main body portion (10) and covers an outer side of the first filter (12). At least a part of the dust scraping assembly is disposed around the outer side of the first filter (12), and is configured to move in a reciprocating manner along an axial direction of the first filter (12), so as to scrape off dust from the first filter (12).
