Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

To facilitate an understanding of the utility model, the utility model will now be described more fully with reference to the accompanying drawings. Several embodiments of the utility model are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides an aluminium impeller for explosion-proof, including the blade body 1, the central fixedly connected with axle sleeve 2 of the blade body 1, the both sides of axle sleeve 2 all are provided with link 3, link 3 adopts the flute profile design, and inside packing has the cotton piece of stereoplasm honeycomb 4, realize advancing, the dirt of straining of giving vent to anger, the top both sides of link 3 all are provided with inlet 5, the bottom of link 3 is provided with liquid outlet 6, realize inside, outer environment humidification, the dust subsides with higher speed, the outside of link 3 is provided with cleaning brush 7, the inner of cleaning brush 7 is fixed in the tip of axle sleeve 2, realize the cotton piece surface automatically cleaning of stereoplasm honeycomb.

In this embodiment, referring to fig. 3, the connecting frame 3 is rotatably connected to the shaft sleeve 2 through a bearing 8, and the bearing 8 is a fully enclosed bearing, so that the rotational resistance is reduced, and the motion stability is improved.
