Clean cabinet-type fresh air ventilator with dustproof function

Abstract

The invention relates to a clean cabinet-type fresh air ventilator with a dustproof function. The clean cabinet-type fresh air ventilator with the dustproof function comprises a main body, a filter screen and a fan. A cleaning mechanism comprises a waste box, a driving assembly, a sliding block and a cleaning assembly. The cleaning assembly comprises a scraping plate, a first spring and a connecting rod. A dustproof mechanism comprises a power assembly, two moving assemblies and two sealing assemblies. Each sealing assembly comprises a supporting shaft and a sealing plate. Each moving assemblycomprises a fixed pulley, a pulling rope, a movable block, a second spring and an adjusting rod. According to the clean cabinet-type fresh air ventilator with the dustproof function, dust on the filter screen can be removed through the cleaning mechanism, so that the situation that the filter screen is blocked by dust, and consequentially, air circulation is affected is avoided; and through the dustproof mechanism, the situation that dust enters the main body when a device is limited, and consequentially, normal work of the interior of the main body is affected is avoided.

Description

technical field [0001] The invention relates to the field of fresh air systems, in particular to a clean cabinet-type fresh air fan with dustproof function. Background technique [0002] The fresh air fan is an effective air purification equipment that can circulate the indoor air. On the one hand, the indoor dirty air is discharged outside, and on the other hand, the fresh outdoor air is sterilized, disinfected, filtered and other measures, and then input into the room. , so that the room is fresh and clean air all the time. [0003] The existing fresh air fans are generally equipped with a filter screen. After long-term operation, the dust in the air is easy to adhere to the filter screen, causing the filter screen to be blocked by dust and affecting the circulation of the air. Not only that, the existing fresh air fan is idle At this time, the dust in the air is easy to flow into the main body from the air inlet, which affects the normal work inside the main body and red...

[0003] The existing fresh air fans are generally equipped with a filter screen. After long-term operation, the dust in the air is easy to adhere to the filter screen, causing the filter screen to be blocked by dust and affecting the circulation of the air. Not only that, the existing fresh air fan is idle At this time, the dust in the air is easy to flow into the main body from the air inlet, which will affect the normal operation of the main body and reduce the practicability of the equipment.
