Description

TECHNICAL FIELD

[0001] The present utility model relates to the technical field of air purification equipment, and in particular discloses a fresh-air ventilation system for internet cafes.

BACKGROUND ART

[0002] An internet cafe is a relatively confined space with poor air circulation; since there are many people in the internet cafe, it is easy for large numbers of bacteria and germs to breed, and there are many people smoking, so the air quality in the internet cafe is relatively poor with a heavy smoke smell. Long-term exposure to such an environment will seriously affect physical health and induce various respiratory diseases. To improve the air quality in internet cafes, fresh-air systems are often installed in internet cafes for air change. At present, the fresh-air systems installed in internet cafes basically only have an air-change function and cannot eliminate harmful substances such as bacteria and germs in the internet cafe, nor can they eliminate the heavy smoke smell in the internet cafe, so improvement is very necessary.

[0009] Preferably, a pin is fixedly connected to one side of the bottom of the top cover, and a slot matching the pin is provided at one side of the top of the housing.

[0010] The present utility model has the following beneficial effects: the present utility model discloses a fresh-air ventilation system for internet cafes having a unique structure; outdoor air is drawn into the air inlet chamber by the fan, the ultraviolet lamp tube is turned on, and under the irradiation of ultraviolet light, the titanium dioxide mesh plates decompose to produce strongly degrading substances which, together with the air flow, are discharged through the air supply outlet into the internet cafe room, which can effectively eliminate the breeding of bacteria and germs in the internet cafe. When the air flow passes beside the tray, it carries molecules of the refreshing essence into the air of the internet cafe, effectively eliminating odors in the internet cafe and having a refreshing effect on the people in the internet cafe. Under the suction action of the exhaust fan, the air in the internet cafe is drawn through the air outlet port into the air outlet chamber and discharged outdoors through the air exhaust port. The structure is simple; air changes can be carried out in the internet cafe, effectively eliminating the breeding of bacteria, germs and the like in the internet cafe and eliminating odors in the internet cafe. The filter A can filter the air drawn into the air inlet chamber, improving air quality. Starting the motor drives the disk to rotate around the air supply outlet, and the air flow in the air inlet chamber passes through the rotating oblique air ducts to form an air flow with changing direction, improving the air diffusion efficiency. The protective mesh plate covers the air outlet port, preventing human hands from touching the blades of the exhaust fan and causing injury, which improves safety. The filter B can filter the air in the air outlet chamber, reducing air pollution. When the top cover is closed onto the housing, the pin is automatically inserted into the slot to lock and fix the top cover and the housing together, improving convenience.
