Description

Energy-saving ventilation device Technical Field The utility model relates to the technical field of building design, in particular to an energy-saving ventilation device. Background The building is a general name of a building and a structure, ventilation is a technology that natural or mechanical methods are adopted to enable wind to pass through and reach a room or a sealed environment, so that sanitation, safety and other suitable air environments are caused, and the ventilation can improve indoor air quality and is beneficial to health. According to an energy-conserving building ventilation unit that discloses in patent number CN118654350B, including the air inlet passageway, air inlet passageway inner chamber both sides are close to the top to and all be provided with the spout on the baffle both sides are close to the position at top, and the air inlet passageway inner chamber both sides are close to the front end and lie in the spout below, and all fixed mounting has the contact arm on the baffle both sides lie in the position of spout below, and the inside movable mounting of two adjacent spouts has stroke device.
