Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a purification and ventilation device for a breeding greenhouse. Background Art

[0002] When breeding in a greenhouse, in order to ensure the circulation of air inside the greenhouse, a ventilation device will be installed on the greenhouse to allow air to circulate inside the greenhouse, so that the environment inside the greenhouse can be more suitable for breeding needs.

[0003] However, there are some shortcomings in the current ventilation devices. When the ventilation devices are in use, since the outside air needs to be introduced into the greenhouse, the outside air enters the greenhouse after passing through the fan and the filter cover.
