A high-efficiency low-resistance air filter core box

Abstract

The invention relates to the field of air purification equipment, in particular to a high-efficiency and low-resistance air filter core box. The high-efficiency and low-resistance air filter core box comprises a top plate, a purifying material, a bottom plate and baffle plates, wherein the baffle plates are arranged on the periphery of the part between the top plate and the bottom plate to jointly form the filter core box; a ventilating plate is arranged in the filter core box and is in a hollow tube shape; ventilating openings are distributed in the side surface. According to the content, an air inlet channel and an air outlet channel are arranged in a purifying material packing layer, are respectively located close to two air circulation surfaces of a filter net and are staggered from each other, so that the problem of overlarge windage resistance caused by thickness increase in the scheme of increasing the purifying material capacity of the purifying material packing layer is solved; the purifying material in the air filter core box is relatively convenient to exchange; and meanwhile, the air purifying capacity of the air filter core box is greatly improved.

Description

technical field [0001] The invention relates to the field of air purification equipment, in particular to an air filter core box with high efficiency and low resistance. Background technique [0002] The air filter box is an important purification structure in the air purification equipment, and its purification ability largely determines the purification ability of the air purification equipment; while the purification ability of the air filter box is determined by the purification material in the air filter box ( Such as activated carbon, sterilizing granular desiccant, etc.), so increasing the capacity of purification materials in a unit space becomes an effective way to improve the purification capacity of the air filter core box. [0003] Some of the air filter core boxes in the prior art directly fill the air-permeable box-shaped space with granular purification materials (such as activated carbon), but such a scheme is only applicable to thinner box-shaped spaces, bec...

Problems solved by technology

[0003] Some of the air filter core boxes in the prior art directly fill the air-permeable box-shaped space with granular purification materials (such as activated carbon), but such a scheme is only applicable to thinner box-shaped spaces, because the more purified materials filled, thicker, the greater the wind resistance, the more difficult it is for the air to pass through the purification material layer, or even the impossibility of passing through, thus failing to achieve the purpose of purifying the air; The modules are spliced ​​together during use, but this solution requires a certain degree of process treatment on the activated carbon structure, which makes the production more difficult and increases the waste in the activated carbon manufacturing process. Subtle changes, this kind of change can just block such a fine pore structure, thereby reducing the service life of the activated carbon filter element. In addition, when users need to replace the activated carbon filter, they need to buy this modular activated carbon, which also makes The replacement of activated carbon in the activated carbon filter is inconvenient, and the consumption cost increases
