Description

Technical Field

[0001] This utility model relates to the field of air filter accessories technology, and more specifically, to an air supply device for an air filter. Background Technology

[0002] An air filter is a device used to purify air. It primarily uses porous filter materials to capture dust from a gas-solid two-phase flow, thus purifying the gas. It is constructed from carefully selected filter materials, such as fine fibers, high-efficiency filter screens, or activated carbon with strong adsorption capacity.

[0003] An air supply component is installed at the air inlet of the air filter. However, the installation of the air supply unit requires the use of multiple locking and sealing parts, which is relatively troublesome and the effect is not good. Therefore, we propose an air supply device for the air filter to solve the above problems. Utility Model Content
