Closed space air flow guiding device with shielding function

Abstract

The invention provides a closed space air flow guiding device with the shielding function. The closed space airflow guiding device with the shielding function comprises a closed space shell provided with a window, a flow guiding annular channel arranged around the edge of the window, and an air feeding device, wherein according to the flow guiding annular channel, a U-shaped airflow channel is defined by a U-shaped inner wall and a U-shaped outer wall; one outer wall face of the U-shaped outer wall is attached to the edge of the window; the opposite faces of the U-shaped inner wall and the U-shaped outer wall are connected though connecting bars; seams are formed in the joints of the U-shaped inner wall and the U-shaped outer wall and provided with a first annular air guiding port and a second annular air guiding port, and the diameter of the first annular air guiding port is smaller than that of the second annular air guiding port; the first annular air guiding port and the second annular air guiding port receive airflow from the U-shaped airflow channel and guides the airflow to flow to the outside of the closed space shell; and the air feeding device conveys air flow to the U-shaped airflow channel of the flow guiding annular channel. The closed space air flow guiding device with the shielding function is installed on a window of a highway ticket booth, and tail gas, peculiar smell and the like of a vehicle can all be discharged out of a closed space.

Description

technical field [0001] The invention relates to the field of fluid technology, in particular to a gas diversion device in a closed space with a shielding function. Background technique [0002] During the whole process of vehicles passing through the ticket booth and interacting with the staff in the ticket booth, the window of the ticket booth must be kept open all the time. The exhaust gas and peculiar smell of the vehicle will enter the airtight ticket booth through the window of the ticket booth, causing physical damage to the staff. hurt. In addition, harmful gases such as smog can easily enter the relatively airtight ticket booth through this window. Since the ticket booth window is the channel for the staff to interact with the outside world, and the frequency of use is extremely high, it is impossible to install some actual automated isolation equipment on the window. Contents of the invention [0003] The object of the present invention is to propose a gas diver...
