Description

Technical Field

[0001] The utility model relates to the technical field of fresh air systems, in particular to an air inlet for fresh air exhaust. Background Art

[0002] The fresh air system is an independent air treatment system consisting of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. An air inlet will be installed at the air inlet of the fresh air system, and a filter will often be arranged inside the air inlet to effectively filter the outside air passing through, and can effectively intercept dust in the gas to prevent a large amount of dust from entering the room. The filter inside the air inlet needs to be replaced after a long period of use to prevent the filter from being blocked. However, when replacing the filter inside the existing air inlet, the air inlet needs to be disassembled as a whole before the filter inside can be disassembled and replaced. This process has many operating steps, is time-consuming and labor-intensive, and is not easy for staff to quickly disassemble and replace the filter, which prolongs the working time of staff.

[0013] Compared with the prior art, the utility model provides an air inlet for fresh air exhaust, which has the following features:

[0014] Beneficial effects:

[0015] 1. The air inlet for fresh air exhaust is driven by the control hand-held rod to move the limit rod out of the limit hole, thereby releasing the fixation of the rotating plate. Then, the control hand-held block drives the rotating plate and the baffle fixedly connected to the inner side thereof to rotate outward, thereby releasing the obstruction of the filter. Then, the filter is taken out from the inner side of the lowermost baffle, thereby completing the disassembly of the filter. This process has fewer operating steps, saves time and effort, and enables the staff to quickly disassemble and replace the filter, effectively shortening the working time of the staff.

[0016] 2. The air inlet for fresh air exhaust continuously squeezes the moving block to the left through the reaction force generated by the extrusion of the return spring, so that the moving block can drive the limit rod to move to the left along the inside of the air inlet until the limit rod passes through the inner wall of the right side of the through groove and is finally firmly inserted into the inside of the limit hole, which effectively improves the fixing effect between the air inlet and the rotating plate, and indirectly ensures the stability of the filter when it is in use.

[0017] 3. The fresh air exhaust air inlet, through the mutual cooperation between the four groups of connecting holes, allows the staff to control the electric screwdriver prepared in advance to drive the screw to rotate along the inside of the connecting hole until part of the screw passes through the inside of the connecting hole and finally rotates into the inside of the designated position. At this point, the installation of the device can be completed, which is convenient for the staff to fix the device. BRIEF DESCRIPTION OF THE DRAWINGS
