Suction Head For Use In A Vacuum Cleaning Appliance, And A Vacuum Cleaning Appliance Comprising Thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vacuum cleaner suction heads tilt upwards when encountering obstacles, obstruct airflow during pivoting, and reduce suction effectiveness in confined spaces like underneath furniture.
Innovation Solution
A suction head with a forward-facing inlet, a U-shaped air channel, and a T-shaped connecting junction that maintains an unobstructed air passageway during pivoting, ensuring constant contact with the surface and efficient debris removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the suction head is designed with a traditional structure, then it can be used for general cleaning purposes, but it tilts upwards when encountering obstacles such as the lower parts of furniture, causing the nozzle to lift away from the surface and diminishing suction effectiveness
Solution Approach 1:
The connecting means is made rotatable to pivot about an axis along the direction of air flow, allowing the air passageway to dynamically adjust and remain open during pivoting movements, preventing the nozzle from tilting upward and maintaining constant contact with the surface for reliable suction effectiveness
2Adaptability or versatility
If the handle or tube portion is lowered or pivoted towards the floor to facilitate insertion of the suction head under furniture, then access to confined spaces is improved, but airflow is obstructed due to the partial closure of the air passageway at the pivot point
Solution Approach 1:
The rotatable connecting means allows the air passageway to dynamically pivot without closing, maintaining open airflow path even when the handle is lowered or pivoted towards the floor, enabling access to confined spaces while preserving air flow rate and suction efficiency
Solution Approach 2:
The air passageway is configured to pivot about an axis along the direction of air flow, adding a rotational degree of freedom that allows the handle to be positioned in various orientations (including lowered positions for under-furniture cleaning) without obstructing the airflow path
3Ease of operation
If traditional hoses or tubes within the handles are bent or folded, then flexibility and maneuverability are improved, but further constriction occurs which limits air flow rate and suction efficiency
Solution Approach 1:
The rotatable connecting means provides controlled flexibility through rotation about a defined axis rather than arbitrary bending or folding, allowing maneuverability for accessing different areas while maintaining an open, unconstricted air passageway that preserves air flow rate and suction efficiency
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective cleaning in restricted spaces by preventing tilting and maintaining uninterrupted suction, even when the handle is lowered or pivoted, enhancing cleaning performance.
Implementation Method 1
an air passageway adapted to direct air flow from the inlet to the outlet, the air passageway comprises an air channel connecting with the inlet at one end, and a hollow connecting means connecting with the outlet at another end; wherein the connecting means is rotatable to pivot about an axis along a direction of the air flow
