Problems solved by technology

[0002] At present, most of the existing ventilation devices are single rotating blades, which have relatively little influence on the wind force caused by rotation, so the wind speed and air volume are relatively small, and the driving ability of wind energy is poor.

Abstract

The invention discloses a coaxial reverse rotation type ventilation device. The coaxial reverse rotation type ventilation device comprises a main horizontal type hollow shell, wherein the centers of the two ends of the main horizontal type hollow shell are each provided with an air flowing space; an annular protrusion structure is arranged in the middle of the outer side of the main horizontal type hollow shell; an annular air reserved space is arranged in the annular protrusion structure; and a main exhaust hole communicating with the outside space and an outer ring of the annular air reserved space is formed in the annular protrusion structure. According to the coaxial reverse rotation type ventilation device, the coaxial technology is utilized, rotation in one direction can be convertedinto rotation in two opposite directions, the two rotation directions are in the same direction, and the influence on the space resistance of a ventilation part is small; then rotation generated by two opposite rotation shafts is utilized for driving fan blades to rotate at a high speed, and opposite air flowing is achieved; and finally, two kinds of wind energy are combined and discharged in a centralized manner, and therefore the wind energy drive capability is improved, and the higher wind speed and the higher wind volume are generated.

Description

technical field [0001] The invention relates to the technical field of ventilation devices, in particular to a coaxial reverse ventilation device. Background technique [0002] At present, most of the existing ventilation devices are single rotating blades, which have relatively little influence on the wind force caused by the rotation, so the wind speed and air volume are relatively small, and the driving ability of wind energy is poor. Contents of the invention [0003] The object of the present invention is to provide a coaxial reverse ventilation device to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a coaxial reverse ventilation device, comprising a main horizontal hollow shell, an air flow space is respectively provided at the center of the two ends of the main horizontal hollow shell, the main horizontal An annular protruding s...
