Description

Technical Field

[0001] This utility model relates to the field of air conditioning and ventilation technology, and more specifically, to an air conditioning and ventilation device. Background Technology

[0002] In large buildings, most use central air conditioning to regulate the indoor environment. Existing central air conditioning systems mostly supply air to the outside through air conditioning ventilation devices. When using existing air conditioning ventilation devices, the overall length of the ventilation device is fixed, which is inconvenient to adjust for different usage environments. The ventilation effect needs to be improved. In addition, when the device is in use, the air outlet is protected by a filter screen for dust prevention. The filter screen is prone to accumulating a lot of dust after long-term use, and the disassembly and assembly operations are relatively troublesome and inconvenient for quick disassembly and assembly. Furthermore, when the device is in use, the stability of the filter screen after installation is poor, and there is a lack of a suitable reinforcing locking mechanism. Utility Model Content
