Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: the filter plate with a circular cross section completely separates the cylinder body, although it can filter the air, it also hinders the circulation of the air
Especially the dust filter plate, because the dust particles are relatively small, the pores on the dust filter plate must also be set smaller, and when the dust accumulated on the dust filter plate is too much, the pores will be blocked, resulting in the worst axial flow fan. Important ventilation effect diminished

Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0035] This embodiment discloses an environment-friendly axial flow fan, such as figure 1 , figure 2 As shown, it includes an air cylinder 1, a propeller 2 connected in the air cylinder 1 along the axis of the air cylinder 1, and a drive motor 3 for driving the propeller 2 to rotate. The air duct 1 is provided with a ring-shaped air deflector 11 along the axis line on the air exhaust side of the propeller 2, and the air deflector 11 is fixed in the air duct 1 by connecting ribs; the air guide 11 and the inner wall of the air duct 1 An annular air guide chamber 12 is formed therebetween, the side of the air guide chamber 12 facing the propeller 2 is an air inlet 121 , and the side facing away from the propeller 2 is an air outlet 122 .
[0036] Such as figure 1 , figure 2 As shown, the propeller 2 includes a number of blades 21 arranged in the circumfere...

The invention relates to the technical field of axial flow fans, and provides an environment-friendly axial flow fan. The environment-friendly axial flow fan comprises an air barrel, a propeller arranged in the air barrel and a driving motor; the inner side of an air outlet of the air barrel is provided with an air deflector, and an air deflection cavity is formed between the air deflector and theinner wall of the air barrel; and the air outlet of the air deflection cavity is provided with an adsorption net for adsorbing dust. When the axial flow fan is operated, airflow can enter the air deflection cavity from an air inlet under propelling of the propeller and is exhausted from the air outlet after the dust is absorbed by the absorption net; and when too much dust is absorbed in the absorption net to block pores, airflow is difficult to pass the adsorption net, the airflow continuously entering the air deflection cavity causes high pressure to be generated in the air deflection cavity, follow-up airflow is hindered from entering, thus, the airflow circulates on the inner side of the air deflector, and reduction of the ventilation effect is avoided.
Description
technical field [0001] The invention relates to the technical field of axial flow fans, in particular to an environment-friendly axial flow fan. Background technique [0002] Axial flow fans are widely used, such as electric fans and air conditioner fans are axial flow fans. The reason why it is called "axial flow type" is that the generated gas flows parallel to the fan shaft, but actually diffuses in a spiral shape along the axis of the fan shaft, and is blown out along the length of the fan shaft under the restriction of the fan shaft. . [0003] In the prior art, the Chinese patent document whose authorization notification number is CN205605465U discloses an automatic axial flow fan for mines, which includes a cylinder in which a motor, a transmission shaft and blades are arranged. The motor is used to drive the transmission shaft and the blades to rotate, so as to achieve the ventilation effect. A filter plate with a circular cross-section is arranged in the cylinder...
