A New Ventilation Device Used in Buildings

Abstract

The invention discloses a new type of ventilation device for buildings. The upper small end of the lower conical pipe of the present invention is arranged in close connection with the lower small end of the upper conical pipe, and a connecting suction cup is arranged between the lower conical pipe and the upper conical pipe. In this way, after the airflow of the lower conical tube flows to the upper conical tube, due to the contraction and diffusion of the conical tube, a certain negative pressure can be formed at the connection with the suction cup, and this negative pressure will make the suction tube suck At the same time, the airflow control mechanism of the present invention can make the flow velocity of the airflow flowing from the lower conical pipe to the upper conical pipe continuously present periodic or non-periodic changes, which can effectively make the suction airflow in the suction pipe also at During the change, it not only facilitates the change of the air flow during humidity adjustment, but also ensures that water molecules escape from the humidity adjustment mechanism, and facilitates the suction of the suction pipe, improving the suction capacity of the suction pipe.

Description

technical field [0001] The invention relates to a building ventilation device, in particular to a novel ventilation device for buildings. Background technique [0002] In building ventilation, fans are generally used to introduce external air into the building. Although this method is simple, one problem is that the humidity of the introduced air cannot be adjusted during ventilation. Another problem is that the current Ventilation facilities are generally arranged in the ventilation shaft. For the ventilation facilities in the ventilation shaft, it can only realize the ventilation of the basement and the surrounding positions connected with the ventilation shaft of the building. For relatively closed areas in the building, such as toilets, It is difficult to achieve ventilation in corridors, etc. Therefore, how to design a ventilation device is very important for the ventilation of buildings. [0003] Therefore, the present invention provides a novel ventilation device for...
