Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1 and 2, a clean room air return window includes a frame 10 embedded in an inner wall of a clean room, and a plurality of blades 11, wherein the blades 11 are disposed in the frame 10, the blades 11 are rotatably connected to the frame 10 through a rotating shaft 12, the blades 11 are disposed to be inclined outward along an inside of the clean room, and a filtering device is disposed between the blades 11 and the blades 11.

Filter equipment sets up in being close to inside one side of toilet, filter equipment includes filter screen 21 and sets up in the fixed strip 22 at filter screen 21 both ends, the fixed strip 22 at filter screen 21 both ends is fixed respectively and is set up in 11 one sides of adjacent blade, filter screen 21 is arranged in the ventilation passageway that forms between two blades 11, filter screen 21 adopts non-woven fabrics or nylon wire to make, filter screen 21 can buckle.

The width of fixed strip 22 equals half of blade 11 thickness, is convenient for set up two filter equipment's fixed strip 22 on same blade 11 for can both set up filter equipment between per two blades 11, thereby all be equipped with filter equipment with the ventilation channel between the blade 11, filter the air through the return air window.

The fixing strip 22 is provided with a fixing hole, the blade 11 is provided with a threaded hole corresponding to the fixing hole, the fixing strip 22 and the blade 11 are fixedly connected through a screw, and the screw penetrates through the fixing hole and is in threaded connection with the threaded hole. Fixing filter equipment and blade 11 through the screw, when people need wash filter screen 21 on the filter equipment, can take off filter equipment through unscrewing the screw and wash, adopt the detachable mode to connect, make things convenient for people to wash filter equipment and change to improve filter equipment's filter capacity.

In this embodiment, the fixed strip 22 adopts adhesive mode and blade 11 to fix, adopts adhesive mode to fix, and convenient and fast more when people need change filter equipment, only need with fixed strip 22 from blade 11 tear can, need not be with the help of other instruments.

When the blades 11 on the return air window are in a parallel opening state, air passes through a ventilation channel between the two blades 11, and the passing air is filtered by the filter screen 21 between the two blades 11, so that the cleanliness of the clean room is improved.

When the blade 11 of the return air window is in a closed state, the filter screen 21 is made of non-woven fabric or nylon net, so that the filter screen 21 has a certain deformation amount and does not unexpectedly close or open the blade 11.

In the above scheme, one side of the blade 11, which is far away from the filtering device, is provided with the rubber strip 30, and the rubber strip 30 is located on the lower surface of the blade 11. When the blades 11 are in a closed state, a gap exists between the blades 11 and the blades 11, and air can enter the clean room through the gap by a small amount, so that the gap between the blades 11 and the blades 11 is filled through the rubber strips 30 on one side of the blades 11, the air is prevented from entering the clean room through the gap, and the whole air tightness of the clean room is improved.

The utility model provides a toilet's return air window, blade set up in the framework, and blade and framework rotatable coupling are equipped with filter equipment between blade and blade, and filter equipment includes the filter screen and sets up in the fixed strip at filter screen both ends, and the fixed strip at filter screen both ends is fixed respectively and is set up in adjacent blade one side. When the blades on the air return window are in a parallel opening state, air passes through a ventilation channel between the two blades, and the passing air is filtered by utilizing the filter screen between the two blades, so that the cleanliness of the clean room is improved.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
