Technical Field

[0001] The utility model relates to the technical field of filter air drying, in particular to a filter air drying device for an air purifier. Background Art

[0002] In the daily use of air purifiers, the filter, as its core component, plays a role in filtering pollutants such as dust, particulate matter, and harmful gases in the air. As time goes by, the filter will gradually accumulate dust and dirt, which not only affects its filtering effect, but may also breed bacteria, mold and other microorganisms, posing a potential threat to the indoor environment. By regularly using cleaning equipment, placing the filter in the equipment, and setting the cleaning and air-drying programs, the equipment can automatically complete the entire cleaning and air-drying process without manual intervention. At the same time, the equipment uses advanced energy-saving technology, which can reduce energy consumption and reduce the impact on the environment while ensuring the cleaning effect.

The upper support of the machine body is provided with a filter conveying mechanism, and a water collecting tank is provided below the filter conveying mechanism. The high-pressure rough washing component, the brush roller component, the high-pressure cleaning component and the water stain air-drying component are arranged in sequence from the feed end to the discharge end of the filter conveying mechanism; the high-pressure rough washing component sprays water to roughly wash the stains on the filter, the brush roller component brushes the filter, the high-pressure cleaning component rinses the filter after rough washing for a second time, and the water stain air-drying component air-dries the rinsed filter.

The negative pressure box works and the air inside the adsorption box is quickly discharged by turning on the negative pressure fan. At the same time, the air outside the negative pressure box is continuously replenished into the negative pressure fan through the negative pressure air duct, forming a higher pressure difference with the outside world. At this time, water stains on the surface of the filter can be quickly sucked into the interior of the negative pressure box, thereby realizing pre-treatment of the filter. Subsequently, when the air-drying duct passes through, the surface can be quickly dried, so that it can be put into use in the shortest time.
