Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a cabinet-type direct-blowing fresh air fan. Background Art

[0002] A fresh air fan is a device used to improve indoor air quality. Its main function is to provide fresh air to the room and expel dirty air from the room. A fresh air fan usually includes a filtration system that can filter out large particles, bacteria, viruses, etc. in the air. Some fresh air fans also have a heat recovery function, which can recover the heat in the exhausted air and reduce energy waste. Since the indoor space is a relatively closed space, the internal air quality is poor after long-term use. In order to improve the indoor air quality, a fresh air fan is used to draw the indoor air out, forming a negative pressure in the room, and the outside air enters the room. However, the cabinet-type direct-blowing fresh air fans currently used are large in size. When the position of the fresh air fan needs to be adjusted, two people are required to carry it to the designated location, which is time-consuming and labor-intensive, consumes manpower, and is inconvenient to use.
