Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a ventilation device in a warehouse. Background Art

[0002] Ventilation is a technology that uses natural or mechanical methods to allow wind to pass through the room or sealed environment without obstruction to create a hygienic, safe and suitable air environment. Frequent ventilation can improve indoor air quality.

[0003] For example, the Chinese patent with the publication number CN216492125U proposes a granary ventilation device, which includes a ventilation cage, a connecting cage and an air blowing assembly. There are multiple ventilation cages, each of which is spaced apart from each other. The ventilation cage includes a cage body and a sensor. The cage body has a cavity and a through hole connected to the cavity. The sensor is a temperature sensor, which is installed in the cavity. There are multiple connecting cages, each of which is respectively arranged between each cage body and connected to each cavity to form an inlet and an outlet that are interconnected end to end. The air blowing assembly is connected to the inlet and electrically connected to the sensor. The granary ventilation device is connected to each cage body through a connecting cage to connect each cavity to form an inlet and an outlet that are interconnected end to end. The air blowing assembly blows air to the inlet, and the wind is blown into the stacked grain evenly through the through hole connected to the cavity, so that the stacked grain is at a suitable temperature to avoid grain damage.

[0004] However, in the actual application of this solution, due to the large difference in temperature and humidity between indoor and outdoor air in different seasons and weather, it is very easy for the gas entering the warehouse to cause the items stored in the warehouse to become moldy and damaged.

[0005] Therefore, how to design a ventilation device in the warehouse has become a problem that we currently need to solve. Utility Model Content
