Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically to an elastic support plate structure for an air filter element. Background Technology

[0002] The purpose of an engine air filter is to effectively filter dust and impurities in the air, increasing the purity of the air entering the combustion chamber and ensuring complete fuel combustion. A dirty air filter will obstruct airflow, reduce the engine's intake air volume, and cause a decrease in engine power.

[0003] Current air filter technology generally suffers from complex installation, insufficient sealing performance, and weak vibration resistance in filter element support structures. These problems lead to leaks and damage during long-term use, especially in high-pressure or high-cleanliness environments, where traditional support structures struggle to meet the demands of efficient operation. Furthermore, inconvenient filter element replacement and high maintenance costs are also pain points in existing designs. To address these issues, we propose an elastic support plate structure for air filter elements. Utility Model Content

[0004] The purpose of this invention is to provide an elastic support plate structure for an air filter element to solve the problems mentioned in the background art.

[0038] Working principle:

[0039] First, the user aligns the positioning blocks 205 on both sides of the frame 203 with the positioning grooves 206 inside the bracket 201 and the first connecting plate 202, and slides them in to ensure the frame 203 is stably positioned in the horizontal direction. Then, the second connecting plate 221 below the frame 203 is inserted into the mounting groove 209 inside the bracket 201, and the second connecting plate 221 above is embedded in the mounting groove 209 of the mounting plate 210. At this time, the mounting plate 210 is fixed between the bracket 201 and the first connecting plate 202 by the engaging connection of the locking block 211 and the locking groove 212, completing the assembly of the entire filter structure 2. During installation, the first rubber pad 207 in the positioning groove 206 and the second rubber pad 208 in the mounting groove 209 respectively play a sealing role, preventing airflow leakage from gaps and improving overall sealing performance.

[0040] When the filter structure 2 is pushed into the filter chamber 102 inside the housing 101 by the hand handle 220, the square connecting plate 213 and the square clamping plate 216 cooperate with each other and form an elastic seal through the third rubber pad 215, further enhancing the leak-proof effect. The baffle 214 is located on the right side of the square connecting plate 213 and plays a limiting and blocking role to prevent the filter structure 2 from moving forward too much.

[0041] During use, external vibrations can cause slight displacement of the filter structure 2. At this time, the connecting column 217 penetrates the outer shell 101 and enters the storage tank 218, connecting with the spring 219. When subjected to impact, the spring 219 is compressed between the connecting column 217 and the inner wall of the storage tank 218, absorbing vibration energy and ensuring smooth operation of the filter structure 2. This reduces mechanical stress and effectively extends the equipment's lifespan. Simultaneously, the filter element body, consisting of filter cotton 204 installed within the frame 203, can efficiently intercept particulate matter, making it suitable for air purification applications.

[0042] Although embodiments of the present utility have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility, the scope of which is defined by the appended claims and their equivalents.
