Ventilation device

Abstract

The utility model discloses a ventilation device which is arranged on an isolation piece. The ventilation device comprises an air guide shell, a separator and at least one fan, wherein the air guide shell is provided with a first air inlet, a first air outlet, a second air inlet and a second air outlet; the separator is arranged in the air guide shell and is used for separating the interior of the air guide shell into a plurality of flow guide spaces; the fan is combined with the air guide shell and is used for leading in and leading out air flow. Therefore the separator can be matched with the ventilation device to supply a good circulating ventilation function by being only provided with a single permeation hole.

Description

technical field [0001] The present invention relates to a ventilation device, in particular to a ventilation device capable of enabling the external space and the internal space to achieve the function of circulating ventilation. Background technique [0002] Please refer to figure 1 As shown, a kind of existing ventilation device 9 is disclosed, and the ventilation fan device 9 is generally installed on the outer wall of a building or the casing of an electronic product, etc., taking the outer wall 91 of a building as an example, generally speaking, the outer wall The outer side of the wall 91 is the external space, and the inner side of the outer wall 91 is the inner space, wherein the outer wall 91 must be provided with an air inlet 911 and an air outlet 912, and a fan 92 is respectively installed at the air inlet 911 and the air outlet 912 In this way, when the fan 92 is in operation, the external airflow can be introduced from the external space to the internal space t...

AI Technical Summary

Problems solved by technology

[0003] Yet this existing ventilating device 9 must offer at least two through-holes (being air inlet 911 and air outlet 912) on this outer wall 91 when actually installing and using, just can reach good circulating ventilation function; Therefore, easy Reduce the overall structural strength of the outer wall 91; moreover, when the outer wall 91 is provided with two through holes at the same time, the two air outlets will occupy too much area on the inner and outer surfaces of the outer wall 91, so the relative It is easy to cause the usable area of ​​the outer wall 91 to be greatly reduced; moreover, one side surface of the fan 92 is exposed to the outer wall 91, which is easy to cause damage to the fan 92 after being exposed to the sun or rain, thereby reducing its service life.
