Suction device with a closure element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction devices lack an efficient mechanism for the closure of the suction inlet, which complicates the insertion and removal of suction hoses and does not ensure a secure seal when not in use.
Innovation Solution
A pivotally mounted closure element with a bearing projection and arm body, allowing for flexible movement between the suction inlet and a provision receptacle, providing a sealing fit and easy handling while being integrated into the suction device housing without a separate bearing holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sliding plate is used for opening/closing the suction inlet, then the suction inlet can be opened and closed, but the mechanism becomes complex and requires a separate bearing holder
Solution Approach 1:
The bearing function is merged directly into the suction device housing. The housing itself forms the bearing receptacle, eliminating the need for a separate bearing holder. This reduces structural complexity while maintaining the opening/closing functionality of the closure element.
2Reliability
If the closure element is rigid, then it provides good sealing, but it cannot be easily inserted into or removed from the suction inlet
Solution Approach 1:
The closure element is designed with dynamic characteristics through its pivotable mounting, allowing it to move between closed and open positions. The arm body can be flexible or deformable, enabling the closure element to be easily inserted into and removed from the suction inlet while maintaining sealing when closed.
3Ease of operation
If a separate bearing holder is provided, then the closure element can be mounted, but the device size increases and stacking becomes difficult
Solution Approach 1:
The bearing holder function is merged into the suction device housing. The housing itself provides the bearing receptacle, eliminating the need for additional separate components. This integration maintains compact device dimensions and enables easy stacking of multiple devices.

AI summary
The invention relates to a suction device (10) with a suction device housing (20) in which a suction turbine (11) is arranged for generating a suction flow (S), wherein the suction turbine (11) has a suction turbine inlet opening (11A) through which the suction flow (S) can flow into the suction turbine (11), and at least one suction turbine outlet opening (11B) through which the suction flow (S) can flow out of the suction turbine (11), wherein the suction device housing (20) has a suction inlet (12) for admitting the suction flow (S) and a dust collection chamber (21) for collecting dust contained in the suction flow (S), wherein a filter element (13) for retaining dust in the dust collection chamber (21) is arranged between the dust collection chamber (21) and a suction turbine inlet opening (11A) of the suction turbine (11), wherein the suction device (10) has a closure element (60) with a closure body (61) for closing the suction inlet (12),which in a closed position (V) closes the suction inlet (12) and in a released position (FS) is removed from the suction inlet (12). The suction device (10) has a provision receptacle (68) for receiving the closure body (61) when the closure body (61) assumes the released position (FS).
