Front Dust Collection for Ground Cleaning Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground cleaning apparatuses face issues with large particle dirt obstructing wet mopping, damage from hard dirt, and inadequate cleaning capabilities, including self-cleaning and dryness, cleanliness, and water splashing during operation.
Innovation Solution
A ground cleaning apparatus with a front dust collection function that performs dry suction first, followed by wet mopping, featuring a rotatable water-absorbing rolling brush, adjustable pressure roller, and multiple hairbrush assemblies for effective dirt removal and self-cleaning, along with flexible water supplementation modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wet mopping is performed first, then dry suction, then the ground cleaning apparatus can clean the ground surface, but large particle dirt obstructs wet mopping and causes damage to the apparatus
Solution Approach 1:
The dust collection device is positioned at the front of the cleaning apparatus to perform dry suction of large particle dirt before the cleaning device performs wet mopping. This preliminary action removes harmful large particles that would otherwise obstruct the wet mopping process and cause damage to the apparatus, resolving the contradiction between cleaning efficiency and apparatus durability.
2Ease of repair
If the pressure roller presses the rolling brush to squeeze out water, then the rolling brush can be cleaned, but the rolling brush surface is pressed together reducing its ability to adsorb dirty water and dirt
Solution Approach 1:
The cleaning apparatus performs periodic alternating actions: first the pressure roller squeezes the rolling brush to remove dirty water and achieve self-cleaning, then clean water is supplied to the rolling brush to restore its water absorption ability. This periodic alternation between squeezing and water supply resolves the contradiction between self-cleaning capability and water absorption ability.
3Productivity
If the pressure roller and rolling brush rotate at high speed to generate cleaning action, then cleaning effectiveness is improved, but accumulated water is easy to splash causing extra water stains
Solution Approach 1:
The water guide assembly is designed to extract and guide the accumulated water generated during high-speed rotation of the pressure roller and rolling brush. By taking out the water from the rotation zone and directing it through designated channels to the dirty water collection container, the system prevents water from splashing onto the cleaned ground, thus resolving the contradiction between cleaning effectiveness and water stain generation.
4Adaptability or versatility
If a threaded conveying rod is used to convey dirt, then sweeping and mopping can be integrated, but the structure becomes more complex
Solution Approach 1:
The threaded conveying rod integrates the functions of dirt collection and conveyance into a single component. As the rod rotates, its threaded structure both gathers dirt from the ground and transports it toward the collection container, merging sweeping and conveyance functions into one element. This reduces overall structural complexity while maintaining integrated cleaning capability.

AI summary
Disclosed is a ground cleaning apparatus having a front dust collection function, including a cleaning device, a water storage device and a dust collection device. The cleaning device includes a rolling brush (1), a washing assembly (2) and a water retaining housing (3). The rolling brush (1) and the washing assembly (2) are both mounted in the water retaining housing (3). The rolling brush (1) is a rotatable water-absorbing rolling brush. The washing assembly (2) is arranged on one side of the rolling brush (1). The washing assembly (2) includes a conveying rod housing (22) and a threaded conveying rod (21) rotatably mounted in the conveying rod housing (22). The conveying rod housing (22) is provided with a dirt outlet (221) in the rotary conveying direction of the threaded conveying rod (21). The conveying rod housing (22) is provided with an opening (222). The water retaining housing (3) is arranged in a sealing fit with the conveying rod housing (22). The water retaining housing (3) and the conveying rod housing (22) can prevent water and dirt from spilling out. The water storage device is provided with a dirty water tank (71). The dust collection device is provided with a dust suction port (81). The dust suction port (81) is arranged on a front side of the rolling brush (1). The dust collection device sucks dirt on the ground by way of the dust suction port (81). Dry suction is performed first, and wet mopping is then performed, such that the service life of the cleaning device is prolonged, and the cleaning effect is better. An access port of a dust collection cover can be flexibly adapted to the dust collection device.
