Particle Receiving Device with Dynamic Closure to Prevent Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing particle receiving devices for vacuum cleaners and cyclone separators lack effective mechanisms to prevent particle leakage, particularly when harmful particles are collected, posing a risk of environmental contamination.
Innovation Solution
A particle receiving device with a selectively displaceable access element and closure element that can be moved into a closure position to seal the access opening, ensuring particles are contained within the device and reducing the risk of environmental contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the access element opening is always open for particle transport, then particle collection efficiency is improved, but particle leakage into the environment increases
Solution Approach 1:
The access element is designed to be dynamically displaceable between an open position (during operation for particle transport) and a closure position (when detached or idle to prevent leakage). This dynamic positioning resolves the contradiction by adapting the opening state to operational requirements.
Solution Approach 2:
The access element is automatically positioned in the closure position before the particle receiving device is detached from the particle outlet, preventing particle leakage in advance. This preliminary action ensures that the opening is closed before contamination can occur during removal or transport.
2Object-affected harmful factors
If the access element is kept closed to prevent particle leakage, then environmental safety is improved, but particle transport into the receiving volume is hindered
Solution Approach 1:
The system dynamically switches between closed and open states based on operational context. During active collection, the access element opens to allow particle transport; during detachment or idle periods, it closes to prevent leakage, thus resolving the productivity-safety contradiction.
Solution Approach 2:
The access element can be automatically actuated to open or close based on the attachment state of the particle receiving device to the particle outlet, eliminating the need for manual intervention and ensuring timely transitions between open and closed states for optimal performance and safety.
3Adaptability or versatility
If the particle receiving device is detached from the particle outlet for maintenance or emptying, then operational flexibility is improved, but particle leakage risk increases
Solution Approach 1:
The access element is automatically positioned in the closure position before the particle receiving device is detached from the particle outlet, preventing particle leakage in advance. This preliminary action ensures that the opening is closed before contamination can occur during removal or transport.
Solution Approach 2:
The access element dynamically transitions to the closure state when the device is detached, maintaining containment safety during maintenance or emptying operations while preserving operational flexibility.

AI summary
A particle receiving device for attachment to a particle outlet of a vacuum cleaner and/or of a cyclone separator and for receiving separated particles, including: a particle receiving volume for receiving the particles, an access element with an access element opening through which the particles can be transported into the particle receiving volume, and a closure element. The access element is selectively displaceable relative to the closure element into a closure position in which the closure element closes access opening, or into an open position in which the closure element releases the access element opening.
