Floor Cleaning Machine Hand-Held Suction Hose for Dust Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning machines suffer from dust pollution in the surrounding environment due to fine dust escaping from the hand-held suction hose, which is not treated with liquid, and the hose's length and storage mechanism are inconvenient for operators.
Innovation Solution
The hand-held suction hose is connected to the suction pipe between the dirt container and suction device, allowing dusty air to be directed into the dirt container alongside air from the suction device, with a liquid supply to bind dust, and a variable, accordion-like design with a receiving cylinder for easy storage and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hand-held suction hose is connected directly to the dirt container, then the hose length and accessibility are improved, but fine dust escapes into the environment through the blower device inlet
Solution Approach 1:
The suction system is segmented into two separate suction sources: the main suction device for ground surfaces and the hand-held suction hose for hard-to-reach areas. Each has its own connection path to the dirt container, allowing independent optimization of their functions while maintaining dust containment through the shared liquid supply system
Solution Approach 2:
The hand-held suction hose connection is integrated within the existing suction pipe structure that connects the main suction device to the dirt container. The hand-held hose connects to a T-connection in the suction pipe, nesting its function within the overall dust collection system while maintaining separate airflow paths
2Adaptability or versatility
If a long hand-held suction hose is used to reach distant positions, then the coverage area is improved, but the hose becomes difficult to store and manage
Solution Approach 1:
The hand-held suction hose is designed as a flexible, dynamically configurable component that can be extended to various lengths depending on the work requirements. The hose can be coiled or arranged in different configurations within the vehicle cabin, allowing operators to adapt its length and positioning to specific cleaning tasks while maintaining ease of storage when not in use
3Object-affected harmful factors
If fine-pored filter screens are used to prevent dust escape, then dust containment is improved, but the volume flow through the blower device is limited
Solution Approach 1:
A liquid supply system is implemented that introduces liquid (water or air-water mixture) into the suction air flow at multiple points, including specifically for the hand-held suction hose. This pneumatic-hydraulic approach binds dust particles in the air stream, causing them to settle in the dirt container rather than escape through the blower device, thereby maintaining both dust containment and adequate volume flow without requiring restrictive filter screens
Solution Approach 2:
The state of the air flow is changed by introducing liquid, transforming it from a dry air stream that carries dust particles to a humidified air stream where dust particles are bound and settled. This parameter change (adding moisture) allows the system to maintain high volume flow while effectively containing dust, eliminating the need for restrictive filtration

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design optimally separates dust in the dirt container, minimizes dust pollution, and facilitates easy operation and storage of the hand-held suction hose, ensuring effective dust containment and reduced liquid consumption.
Implementation Method 1
it is known to introduce water, for example, into this air flow with the aid of a liquid supply device, which binds the fine dust in this air flow so that it can be separated more easily into the dirt container
Implementation Method 2
a fan device for generating an air flow into the dirt container

AI summary
The floor cleaning machine has a suction device (13), which is supported on a chassis (1) and is arranged for extracting debris from a surface-to be cleaned (5), where a dirt container (11) for receiving the return goods is mounted on the chassis. A blower unit (17) is provided for generating an air flow in the dirt container. A suction pipe (15) has a terminal (29), which is provided in the section between the dirt container and the suction device, where a hand-held suction hose (31) is connected to the terminal.
