Enclosed Air Compressor with Remote Dust and Moisture Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium-or small-sized air compressors and inflator machines lack effective filtration systems to prevent powdery dust, sand/gravel, and moisture from entering the device, leading to damage and corrosion of internal components, thereby reducing their service life.
Innovation Solution
An enclosed air compressor structure featuring remote filtering, which includes an externally mounted filter assembly connected to the air compressor, filtering air before intake, and a carrying receptacle that conceals the compressor and filter to protect against environmental exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no filter device is provided in the air compressor, then the device structure remains simple and manufacturing cost is low, but powdery dust, sand/gravel, and moisture can enter the interior causing damage to motor and cylinder block
Solution Approach 1:
The patent divides the air compressor system into separate functional modules: the air compressor assembly and the filter assembly are distinct components connected through guide tubes. This segmentation allows the filter to be independently mounted and maintained without affecting the compressor's core functionality, resolving the contradiction between adding protection and maintaining structural simplicity.
Solution Approach 2:
The patent introduces guide tubes as intermediary components that connect the filter assembly to the air compressor inlet. These guide tubes serve as mediators that channel filtered air into the compressor while maintaining a clean separation between the filtration system and the compression system, enabling protective function without direct structural integration.
2Ease of repair
If filter assembly is externally mounted, then maintenance and replacement become easier, but the filter is more exposed to environmental damage
Solution Approach 1:
The patent positions the filter assembly in a different spatial dimension relative to the air compressor - externally mounted but integrated through guide tubes. This dimensional separation allows the filter to be accessed and maintained independently while the overall assembly structure provides environmental protection, resolving the contradiction between ease of maintenance and environmental exposure.
3Object-affected harmful factors
If the air compressor is enclosed in a carrying receptacle, then protection against environmental exposure is improved, but the device becomes more bulky and harder to transport
Solution Approach 1:
The carrying receptacle is designed to serve multiple functions: it provides environmental protection for the air compressor assembly, acts as a mounting structure for the filter assembly, and serves as a transport container. This multi-functionality resolves the contradiction by making the protective enclosure beneficial for both protection and portability rather than adding separate protective and transport components.
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
Effectively filters out powdery dust, sand/gravel, and moisture, preventing damage and corrosion, thereby increasing the service life of the air compressor and enabling its use in severe environments.
Implementation Method 1
the filter assembly is connected externally to the air compressor assembly and is located in the receiving space of the carrying receptacle... effectively filter off powdery dust, sand/gravel, and moisture entraining air

AI summary
An enclosed air compressor structure featuring remote filtering includes a carrying receptacle, an air compressor assembly, and a cover plate. The carrying receptacle and the cover plate are combinable to have the air compressor assembly arranged, in a concealed manner, in the interior of the carrying receptacle. The air compressor assembly has an inlet end that is connected with a first guide tube and is connected to and in communication with a filter assembly and an outlet end that is connected with a second guide tube and is connected to and in communication with an exhaust valve, so that external air moves through the filter assembly and the first guide tube to get into the air compressor assembly, and compressed air is discharged through the second guide tube and the exhaust valve. The externally mounted filter assembly filters off powdery dust, sand/gravel, and moisture contained in air.
