Solution Overview
Problem
Existing air filter cleaning methods for heavy off-road and over the road vehicles are inefficient, as they often damage the filtering medium or fail to remove all particulates, especially when using high-pressure air or manual striking, and are not suitable for air filters of various lengths and diameters.
Innovation Solution
A portable apparatus using pressurized fluid flow to rotate air spraying jets within the air filter's aperture, with a set of plates and centering pins for proper positioning and efficient air flow direction, allowing for cleaning of air filters of different sizes with low air pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high pressure air is used to clean air filters, then cleaning effectiveness is improved, but the filtering medium may be damaged
Solution Approach 1:
The invention changes the pressure parameter from high to low, using low pressure air flow to rotate the cleaning member and remove particulates without damaging the filtering medium, while still achieving effective cleaning through the rotational motion
Solution Approach 2:
The invention introduces rotational motion to the cleaning process, where the cleaning member rotates under air flow to dynamically engage with the filtering medium surface, enhancing cleaning effectiveness without requiring high static pressure that could cause damage
2Device complexity
If manual striking method is used to clean air filters, then equipment complexity is reduced, but cleaning completeness deteriorates
Solution Approach 1:
The invention uses rotational motion of the cleaning member to continuously sweep across the filtering medium surface, ensuring complete coverage and removal of particulates, which static manual striking cannot achieve
Solution Approach 2:
The invention uses pneumatic power to rotate the cleaning member, replacing manual mechanical striking with a controlled air-driven rotational system that achieves more complete cleaning while remaining relatively simple in design
3Reliability
If air filter replacement is performed frequently, then engine performance is maintained, but operating costs increase
Solution Approach 1:
Instead of discarding (replacing) the air filter when it becomes dirty, the invention recovers its functionality by cleaning and removing accumulated particulates, allowing the filter to be reused and reducing replacement costs
Solution Approach 2:
The invention enables the air filter to serve itself by providing a cleaning mechanism that can be applied directly to the filter, removing the need for professional service or expensive replacement and allowing operators to maintain the filter independently
4Productivity
If high air pressure is used for cleaning, then particulate removal is improved, but operator effort and concentration requirements increase
Solution Approach 1:
The invention uses pneumatic pressure to automatically rotate the cleaning member, converting the operator's manual effort into automated rotational motion that achieves thorough cleaning without requiring sustained operator concentration or physical strain
Solution Approach 2:
The rotational motion dynamically positions the cleaning member across the entire filtering medium surface, ensuring comprehensive coverage and effective particulate removal without requiring the operator to manually manipulate high-pressure air streams or apply excessive force

AI summary
An apparatus for cleaning air filters utilizes a pressurized fluid flow, preferably air, to rotate a set of air spraying jets inside a hollow interior of a filter in order to remove particles from the filter. To ensure proper positioning of the jets in relation to the filter the present invention uses a set of plates with slots and pins, wherein the pins secure the apparatus on one end of the filter. The set of plates also at least partially blocks the flow of air out of the ends to more efficiently direct the flow of air from the jets to the filter. The jets then may be moved reciprocally along the length of the filter for cleaning purposes.
