[0007] Further, the filtering fan further includes a nozzle, and the nozzle is arranged between the air supply channel and the filter element.

[0008] Further, the number of the air inlet channels is 3.

[0009] Compared with the prior art, the filtering fan of the utility model includes a housing, a fan, a filter element, and a dust collection box. The housing is provided with an air inlet channel, an air supply channel, and an air outlet channel. The air supply channel is communicated with and perpendicular to the air inlet channel, and the air supply channel is communicated with and parallel to the air outlet channel. The fan is located in the air supply channel, the filter element is located between the air supply channel and the air outlet channel, and the dust collection box is slidably installed at the bottom of the housing and is located below the filter element. When in use, external air enters the housing through the air inlet channel, the activated carbon particles adsorb the dust in the air inlet channel, the adsorbed dust falls into the dust collection box through the sieve holes, and the fan sends the healthy air out of the housing through the air outlet channel. The user can clean the filtering fan by cleaning the dust collection box, which is convenient to disassemble, safe and reliable, and improves work efficiency. Description of the Drawings

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be another intermediate component through which it is fixed. When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may also be another intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may also be another intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0017] Figures 1-3 The filter fan of the present utility model includes a housing 10, a fan 20, a filter element 30, a dust collection box 40 and a nozzle 50.

[0018] The housing 10 is provided with an air inlet channel 11, an air supply channel 12, and an air outlet channel 13. The air supply channel 12 is connected to and perpendicular to the air inlet channel 11, and the air supply channel 12 is connected to and parallel to the air outlet channel 13.
