Description

Technical Field

[0001] The utility model relates to the technical field of building ventilation equipment, in particular to building energy-saving ventilation equipment. Background Art

[0002] Building ventilation is divided into natural ventilation and mechanical ventilation, which means that the polluted air in the building is discharged to the outside directly or after purification, and then fresh air is replenished to keep the indoor air environment in line with hygiene standards.

[0025] In this embodiment, please refer to Figure 4 The baffle cleaning mechanism 7 includes a spray pipe 701 installed on the front of the assembly panel 3 and located on the top of the ventilation damper 4. One end of the top of the spray pipe 701 is connected to the delivery branch pipe 702. The bottom of the spray pipe 701 is connected to multiple groups of evenly distributed spray heads 703. Both ends of the bottom of the spray pipe 701 are provided with connecting brackets 704. The bottom end of the connecting bracket 704 is fixed with a water collection box 705.
