Air purifying unit

Abstract

The invention discloses an air purifying unit and relates to the field of air purifying equipment. The air purifying unit comprises a housing. Air inlet holes are formed in two side faces of the housing; filter screen slots are separately arranged on the back, close to the air inlet holes, of the housing; an initial effect filter screen is inserted into each of the filter screen slots; air filtered by the initial effect filter screens are successively purified through a fan device and an efficient filter; the fan device comprises an air partition plate, a fan and a fan bottom plate; a cavity is formed in the air inlet of the air partition plate, the fan is mounted in the cavity, and the fan bottom plate is mounted at an air outlet of the fan; the air purifying unit has the advantages of being high in initial effect filter efficiency, smooth to intake air and fast to blow; a plurality of air outlet nozzles are mounted in an air outlet panel and the angles of the nozzles can be adjusted, so that air can be blown to different angles, and the fan bottom plate plays roles of guiding air in a positive pressure chamber and accelerating air to pressurize.

Description

technical field [0001] The invention relates to the field of air purification equipment, in particular to an air purification unit. Background technique [0002] The FFU (Fan Filter Unit) in the prior art uses the air intake from the back of the machine body, and needs to protrude a part from the back of the machine body to install the primary filter, which not only causes the space of the primary filter air intake to be cramped, but also leads to air intake. Insufficient quantity also makes the structure of the body abnormal; leading to the following problems in the existing FFU: [0003] 1. The protruding air inlet and primary filter installed on the back increase the size of the body, resulting in abnormal shape of the body, which is unfavorable to product installation, matching, transportation and aesthetics; [0004] 2.

AI Technical Summary

Problems solved by technology

[0002] The FFU (Fan Filter Unit) in the prior art uses the air intake from the back of the machine body, and needs to protrude a part from the back of the machine body to install the primary filter, which not only causes the space of the primary filter air intake to be cramped, but also leads to air intake. Insufficient quantity also makes the structure of the body abnormal; leading to the following problems in the existing FFU:

[0003] 1. The protruding air inlet and primary filter installed on the back increase the size of the body, resulting in abnormal shape of the body, which is unfavorable to product installation, matching, transportation and aesthetics;

[0004] 2. Since the primary filter is installed at the air inlet of the fan, it is easy to cause partial blockage of the primary filter when the fan sucks air, which will affect the air inlet speed and lead to low air outlet efficiency;

[0005] 3. Since the primary filter is installed at the air inlet of the fan, the initial resistance is large when the fan sucks air, and there is not enough buffer space, resulting in cramped air intake, which affects the air intake efficiency;

[0006] 4. The size of the primary filter is limited, which indirectly shortens the service life of the high-efficiency filter;

[0007] 5. When the FFU unit is used vertically, when the erected FFU is placed against the wall, it will cause insufficient air intake;

[0008] 6. It is not possible to supply air from multiple angles, fixed directions, and long distances, and to provide both long and short distances;

[0009] 7. Since the fan impeller is close to the back of the machine, and the noise of the unit is low, if you do not notice that the machine is not turned off and then clean or replace the primary filter, it may cause injury to your fingers and cause a safety hazard
