Solution Overview
Problem
Traditional cleaning devices leave floors wet and slippery, leading to accidents and water stains, and existing solutions do not effectively address this issue.
Innovation Solution
A ground cleaning device with a brush assembly, fan assembly, and switching mechanism that directs airflow to either dry the floor quickly or reduce noise and wind direction based on the floor's condition, using a switching mechanism to control airflow through multiple outlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cleaning devices use a scraper, sponge, or cloth to wipe the floor, then water can be absorbed and the floor can be cleaned, but the floor remains wet and slippery for a long time
Solution Approach 1:
The patent uses a fan assembly to generate airflow that rapidly evaporates residual water on the floor surface. The air outlet directs high-velocity air onto the cleaned area, accelerating the drying process through pneumatic evaporation, thus reducing floor drying time while maintaining safety.
Solution Approach 2:
The patent utilizes the phase transition of water from liquid to vapor by directing heated or high-velocity air onto the wet floor surface. This accelerates evaporation and drying, transforming the state of residual water and significantly reducing the time the floor remains wet and slippery.
2Productivity
If the air outlet directs airflow to the rear lower side to dry the floor, then floor drying efficiency is improved, but wind noise and direct airflow to the user increase
Solution Approach 1:
The patent employs a switching mechanism that dynamically changes the airflow direction based on operational needs. The air outlet can be switched between directing airflow to the rear lower side (for efficient floor drying) and to the front side (for reduced noise and user comfort), making the system adaptable to different operational phases.
Solution Approach 2:
The air outlet is divided into multiple directional outlets or can be switched between different orientations. This segmentation allows the system to direct airflow to different locations (rear lower side for drying, front side for noise reduction) independently, enabling optimized performance for each function without compromise.
3Object-affected harmful factors
If the air outlet directs airflow to the front side of the main body, then wind noise is reduced and user experience is improved, but floor drying function is weakened
Solution Approach 1:
The switching mechanism enables dynamic adjustment of airflow direction. During the floor cleaning phase, airflow is directed to the rear lower side for efficient drying. During subsequent phases, the same air outlet can be switched to direct airflow to the front side, reducing wind noise and improving user comfort without permanently sacrificing drying capability.
Solution Approach 2:
The system employs periodic switching between different airflow directions. The air outlet alternates between directing flow to the rear (for drying) and to the front (for noise reduction), allowing the system to achieve both floor drying efficiency and user comfort at different time intervals based on operational requirements.

AI summary
The present disclosure describes a ground cleaning device that comprises a ground brush, a main body, and a fan. The fan may be located inside the main body and may comprise an air inlet and an air outlet. The main body may comprise a main air outlet channel, a front air outlet channel, and a rear air outlet channel. One end of the main air outlet channel may be connected to a switching device, which has a first state and a second state. Based on the switching device being in the first state, the switching device may close the rear air outlet channel to disconnect the main air outlet channel from the rear air outlet channel. Based on the switching device being in the second state, the switching device may open the rear air outlet channel to connect the main air outlet channel to the rear air outlet channel.
