Description

Technical Field

[0001] This utility model relates to the field of seedling rooms, and in particular to a ventilation mechanism for artificial light seedling rooms. Background Technology

[0002] A search of Chinese patents revealed publication number CN221615862U, which discloses a ventilation device for livestock farming. This device includes an exhaust pipe and a fan. The fan is installed inside the exhaust pipe. An integrally formed mounting plate is formed on the outer wall of one end of the exhaust pipe. The center point of the mounting plate is located on the axis of the exhaust pipe. Through holes are formed at all four corners of the mounting plate. A sealing groove with a closed end is also formed on the mounting plate located outside the exhaust pipe. A sealing ring is installed in the sealing groove to fit against the wall. A pair of horizontal locking blocks are fixed to the mounting plate, positioned between the locking blocks and the exhaust pipe. The cross-section of the locking blocks is "7"-shaped, with the inner corners of the same pair of locking blocks facing each other. An air purification component is secured between the locking blocks. The beneficial effects of this invention are: the mounting plate is fixed to the outer wall by expansion screws, and under the action of the sealing ring, the air in the livestock shed is drawn into the exhaust pipe by the fan, flows through the air purification component, and is then discharged after purification, avoiding environmental pollution to the atmosphere.

[0003] Existing ventilation systems are inconvenient for assembling and disassembling fan blades. Generally, ventilation devices use exhaust fans, but after prolonged use, dust and dirt accumulate on the fan blades, affecting ventilation efficiency. Cleaning requires disassembly, and since the blades are usually bolted to the shaft, tools are needed for assembly and disassembly, making the process cumbersome, increasing workload, reducing efficiency, and making them inconvenient to use. Furthermore, they lack a sealing function. Seedling rooms require heating when temperatures are low, but typical ventilation fans are direct-flow type, causing heat inside the seedling room to escape to the outside, affecting insulation and increasing energy consumption. To address these problems, we propose a ventilation system for artificial light seedling rooms. Utility Model Content
