In order to solve the technical problems, the technical scheme adopted by the utility model is as follows.

The cylindrical multifunctional composite filter screen comprises a pair of annular fixed end covers, and the inner edge and the outer edge of each fixed end cover are respectively provided with a first clamping groove and a second clamping groove; the edge of the inner ring between the two fixed end covers is provided with a reinforcing net for increasing the overall stability, and the reinforcing net is connected in the first clamping groove of the fixed end cover; an activated carbon layer for adsorbing peculiar smell and harmful gases is sleeved outside the reinforcing net; an HEPA filter layer for efficiently filtering air is sleeved outside the active carbon layer, an antibacterial filter layer is sleeved outside the HEPA filter layer, and an initial filter layer for filtering large-particle impurities is sleeved outside the antibacterial filter layer; the two ends of the primary filter layer are respectively clamped in the second clamping grooves.

According to the technical scheme, the fixed end cover is a metal end cover, a plastic end cover or a paper end cover.

Further optimizing the technical scheme, the antibacterial filter layer comprises a nano silver filter screen.

Further optimize technical scheme, the thickness on antibiotic filter layer, HEPA filter layer, activated carbon layer equals, and just the gross thickness of just imitating filter layer, antibiotic filter layer, HEPA filter layer, activated carbon layer and reinforcing mesh is less than fixed end cover width 2 cm.

Further optimize technical scheme, the stiff end lid that is located the upper portion is fixed and is provided with a plurality of fixed buckles that are used for easy to assemble.

Due to the adoption of the technical scheme, the technical progress of the utility model is as follows.

The cylindrical multifunctional composite filter screen provided by the utility model is provided with the primary filter layer, the antibacterial filter layer, the HEPA filter layer, the activated carbon layer and the reinforcing mesh which are clamped between the two fixed end covers, can effectively resist bacteria and viruses, adsorb harmful gases such as peculiar smell and formaldehyde, and can efficiently filter and intercept PM 2.5. The utility model has the advantages of high efficiency, powerful function, low resistance, small volume, light weight, easy installation and long service life.

wherein: 1. the filter layer is just imitated, 2, antibiotic filter layer, 3, HEPA filter layer, 4, activated carbon layer, 5, reinforcing mesh, 6, fixed end cover, 8, first draw-in groove, 9, second draw-in groove, 10, fixed knot.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The multifunctional composite cylindrical filter screen is shown in fig. 1 to 3 and comprises an initial filter layer 1, an antibacterial filter layer 2, a HEPA filter layer 3, an activated carbon layer 4, a reinforcing mesh 5, a fixed end cover 6, a first clamping groove 8, a second clamping groove 9 and a fixed buckle 10.

The fixed end cover 6 is a pair of annular metal end covers, plastic end covers or paper end covers, a first clamping groove 8 is formed in the inner edge of the fixed end cover 6, and a second clamping groove 9 is formed in the outer edge of the fixed end cover 6; and a plurality of fixing buckles 10 are fixedly arranged on the fixing end cover 6 positioned at the upper part for convenient installation.

The inner ring edge between two fixed end covers 6 is provided with reinforcing mesh 5 for increase holistic stability, and reinforcing mesh 5 joint is in fixed end cover 6's first draw-in groove 8. The outside cover of reinforcing net 5 is equipped with activated carbon layer 4, and activated carbon layer 4 is used for adsorbing peculiar smell and harmful gas. The outside cover on active carbon layer 4 is equipped with HEPA filter layer 3, and HEPA filter layer 3 is used for carrying out the high efficiency filtration to the air, and the outside cover of HEPA filter layer 3 is equipped with antibiotic filter layer 2, and antibiotic filter layer 2 includes the nano silver filter screen. The outside cover of antibiotic filter layer 2 is equipped with and just imitates filter layer 1, just imitates filter layer 1 and is arranged in the large granule impurity that filters the mingled with of air. The two ends of the primary filter layer 1 are respectively clamped in the second clamping grooves 9 of the two fixed end covers 6.

The thicknesses of the antibacterial filter layer 2, the HEPA filter layer 3 and the activated carbon layer 4 are equal, and the total thickness of the primary filter layer 1, the antibacterial filter layer 2, the HEPA filter layer 3, the activated carbon layer 4 and the reinforcing net 5 is smaller than the width of the fixed end cover 6 by 2 cm.

When the air purifier is actually used, gas is firstly filtered through the primary filter layer 1 to remove large-particle impurities, then is sterilized through the antibacterial filter layer 2 to inhibit bacteria from breeding in the filter layer, and finally is adsorbed through the HEPA filter layer 3 to adsorb fine particles and block PM2.5, and finally is adsorbed through the active carbon layer 4 to adsorb harmful compounds such as peculiar smell, formaldehyde and the like in the gas. The method adopts a mode of combining a plurality of means to purify harmful substances contained in human breath, thereby increasing the purification effect.

When the filter layer needs to be replaced, the fixing end cover 6 is detached at first, then the filter layer is detached from the inside to the outside in sequence, the detached filter layer is placed on a horizontal working face, then the filter layer is cleaned and dried respectively, and then the filter layers are sequentially installed on the fixing end cover 6.
