Technical Field

[0001] The utility model relates to an air volume adjusting mechanism of a fresh air system, belonging to the technical field of fresh air systems. Background Technique

[0002] The fresh air system conveys fresh air into the room on one side of the enclosed room by using an air inlet device, and then discharges the air to the outside on the other side by using an air exhaust device, forming a "fresh air flow field" in the room, so as to meet the fresh air replacement needs of the room; in large-area office areas, a duct-type fresh air system is usually adopted. However, in large office spaces, due to the different installation positions of each fresh air outlet, the air volume of the fresh air outlet at the far end is relatively small, resulting in the failure to meet the fresh air demand of users at the far end, and the air quality and physical comfort of users at the far end are poor. Content of the Utility Model

The socket is electrically connected to the displacement device and the axial flow fan through internal cables respectively. The plug is electrically connected to an external control system through an external cable.

[0007] In order to facilitate later maintenance, one end of the box body far away from the air duct has an opening, and a cover body is detachably connected at the opening.

[0008] As a preference of the utility model, the displacement device includes an electric push rod, and the axial flow fan is installed at the end of the actuating rod of the electric push rod.

[0009] Further, the displacement device further includes two slide rails, which are respectively arranged at the top and bottom inside the box body and extend into the air duct. Sliders corresponding to and slidably connected with the two slide rails are respectively arranged at the top and bottom of the axial flow fan, and a vibration damping rubber pad is arranged between the axial flow fan and the slider.

[0013] The present utility model is installed in the fresh air system pipeline and is close to the fresh air outlet at the far end;

[0014] When the fresh air demand of the user at the far end cannot be met, the displacement device is used to move the axial flow fan so that the axial flow fan moves from inside the box body to inside the air duct, and then the axial flow fan is started. Under the action of the axial flow fan, more fresh air flows to the fresh air outlet at the far end, thereby increasing the air volume of the fresh air outlet at the far end, meeting the fresh air demand of the user at the far end, and improving the air quality and the body feeling comfort degree of the user at the far end;

[0015] When the fresh air demand of the user at the far end decreases, the axial flow fan is turned off, and the displacement device is used to move the axial flow fan so that the axial flow fan moves from inside the air duct to inside the box body, thereby avoiding the axial flow fan from obstructing the fresh air flow inside the air duct, keeping the air flow channel inside the air duct unobstructed, and reducing the wind resistance.
