Cleaner Nozzle Detachment Mechanism for Easy Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaners face difficulties in easily switching from automatic to manual cleaning modes due to nozzle detachment issues, which complicates the sealing of the flow path and affects cleaning performance.
Innovation Solution
A cleaner design featuring a nozzle with a push button and detachment unit that allows intuitive detachment from the main body, optimizing the sealing of the flow path and simplifying the structure by seating the dust box on a connector connecting the main body and nozzle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the nozzle is positioned in close contact with the floor surface for automatic cleaning, then cleaning effectiveness is improved, but the nozzle becomes difficult to drag when performing manual cleaning due to being stuck on thresholds
Solution Approach 1:
The cleaner system is divided into two separate nozzles: a first nozzle for automatic cleaning that contacts the floor surface, and a second nozzle for manual cleaning that does not contact the floor surface. This segmentation allows each nozzle to be optimized for its specific function, resolving the contradiction between cleaning effectiveness and ease of operation.
2Length of moving object
If the connection flow path is shortened to reduce the overall length of the cleaner, then the driving area is improved, but the sealing performance of the connection flow path deteriorates due to the detachment structure
Solution Approach 1:
The detachment structure is positioned at the rear end of the connection flow path rather than along its length, allowing the connection flow path to be short while maintaining sealing performance. The detachment pin engages with a detachment groove at the rear end, enabling nozzle detachment without compromising the sealing of the shortened connection flow path.
3Adaptability or versatility
If the detachment structure is mounted on the connection flow path, then the nozzle can be detached, but the user has to see the bottom of the main body to find the detachment structure
Solution Approach 1:
Instead of mounting the detachment structure on the main body, the detachment structure is inverted and mounted on the nozzle itself. The detachment pin is provided on the nozzle, and the detachment groove is provided on the connection flow path of the main body, allowing the user to easily locate and operate the detachment structure on the nozzle without needing to see the bottom of the main body.
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 easy switching between automatic and manual cleaning modes while maintaining optimal sealing and cleaning performance, simplifying the structure through part integration.
Implementation Method 1
when the user places the nozzle on the surface to be cleaned with holding the cleaner nozzle or the main body by hand in a state in which the suction device generates a suction force by a driving force of an electric motor, the nozzle sucks a foreign substance such as dust on the surface to be cleaned by the suction force
Implementation Method 2
an elastic member which is coupled to the rotating shaft and the detachment unit and which returns the detachment unit to an initial state thereof by an elastic force

AI summary
A cleaner including: a main body having a first connection flow path which is formed in an outside thereof; and a nozzle having a suction port through which air is introduced: wherein the nozzle comprises: a case in which the suction port and a second connection flow path are formed, the second connection flow path which is hooked to the first connection flow path, a push button able to linearly move through one surface of the case in a predetermined pressing direction; and a detachment unit mounted in the case to be rotated about a rotating shaft positioned in a direction parallel to the pressing direction, and interlocked with the push button to release hook coupling of the first connection flow path and the second connection flow path when rotating.
