3. The utility model discloses well filter cloth bag adopts the reverse hanging setting, filters the cloth bag opening towards the return air chamber, and the afterbody adopts the clip to clip fixedly, collects the dust that gets into from the return air chamber better.

4. The utility model discloses a be provided with five filtration sacks in the rose box, air cleaner current relatively only has a filtration window, the utility model discloses a filtration efficiency has improved five times.

Drawings

FIG. 1 is a schematic structural view of an air filter for a return air inlet of a clean workshop according to the present invention;

fig. 2 is the utility model relates to a be arranged in clean workshop return air inlet card strip and filter sack connected state sketch map.

In the figure: 1. the air filter comprises an air filter body, 2, a filter box, 21, a door plate, 22, a buckle, 23, a clamping groove, 24, a cross rod, 25, a clamp, 3, an air return cavity, 4, a filter cloth bag, 41 and a clamping strip.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides an air filter for a clean workshop air return opening, the air filter body 1 is made of a stainless steel frame, and includes a filter box 2 arranged at the upper part and a return air cavity 3 arranged below the filter box 2 and communicated with the filter box 2, the return air cavity 3 is a fan-shaped cavity, the mouth of the return air cavity 3 is in a gradient arc shape, and the purpose of the design is convenient for air intake and dust collection; the filter box 2 is connected with the air return cavity 3 into a whole, the three side surfaces of the lower part of the filter box 2 are respectively provided with a clamping groove 23, and the front surface of the filter box 2 is provided with a door plate 21 with a buckle 22, so that the filter box 2 door can be conveniently opened and closed.
