Description

A ventilation device

Technical Field

The utility model belongs to the field of ventilation and air exchange, in particular to a ventilation and air exchange device.

Background technique

Fresh air is very important to us at all times. Staying in a closed space for too long will cause dizziness, chest tightness, and difficulty breathing. If you use fire in winter, poor air circulation will cause carbon monoxide poisoning, which may seriously affect your life. Air circulation is not only important for humans, but also for the breeding of some livestock and poultry. If the air in the farm is often not circulated, pathogens will be produced, and in severe cases, a large number of livestock may die. Therefore, air circulation is far more important than you think.

In the prior art, most of the equipment is driven by an electric motor. Without starting the motor, ventilation cannot be performed. After starting the equipment for ventilation, fresh air cannot be dispersed in time, and the air in the room cannot be replaced evenly. Natural air circulation is required to completely replace the air in the room, which will lead to slow work efficiency and waste a lot of energy.

For this reason, the utility model proposes a ventilation and air exchange equipment.
