Airflow Exchange Device

Abstract

An airflow exchange device is used to reduce the installation difficulty, and comprises an assembling plate, a spacer, a pedestal and a guide duct. The assembling plate comprises a fixing part and a first combining part, and the fixing part is used to fix the assembling plate to an isolating member. One end of the above spacer is equipped with a second combining part which can be combined with the first combining part of the above assembling plate mutually. The above pedestal is combined with the above assembling plate, and the above guide duct comprises a pipe body and a sleeve. The spacer is accommodated in the pipe body, and the pipe body comprises the relative first and second end parts. The sleeve is arranged at the first end part, and the second end part abuts against the above assembling plate.

Description

technical field [0001] The invention relates to an air exchange device, in particular to an air exchange device capable of enabling the external space and the internal space to achieve the function of circulation and ventilation. Background technique [0002] Please refer to figure 1 Shown, is a kind of existing air flow exchanging device 9, comprises an air guide pipe body 91, a spacer 92, sleeve pipe 93 and a base 94, and this air guide pipe body 91 two ends respectively form a first end part 911 and a second end part 912, the first end part 911 and the second end part 912 can be respectively arranged in an outdoor space and an indoor space. Thereby, the air exchange device 9 can provide an air exchange function, so that the air in the outdoor space and the indoor space can communicate with each other. [0003] During the installation process of the above-mentioned existing air exchange device 9, the operator must pass the air guide pipe body 91 through a through hole pr...

AI Technical Summary

Problems solved by technology

However, the position of the air guiding pipe body 91 is easy to slide in the above-mentioned through hole, and once the first end 911 or the second end 912 accidentally sinks into the through hole, the operator must move to another part of the spacer. Only one side can push the air guiding pipe body 91 back to the correct position, so that the installation of the existing air exchange device 9 can be continued, making the above-mentioned installation process difficult to execute.

In addition, when the air guide pipe body 91 cannot be fixed in advance, since the existing air exchange device 9 is usually arranged at a position with a higher level (for example: close to the ceiling) or a lower position (for example: close to the ground), if The operator still needs to adjust the position of the air guide pipe body 91 during the installation process, which will make the installation of the existing air exchange device 9 more difficult

[0004] In view of this, it is urgent to provide a further improved air exchange device to solve the problem of "difficult installation" of existing air exchange devices
