Description

Air purifier dust removal device

Technical Field

The utility model relates to the technical field of air purifiers, in particular to a dust removal device for an air purifier.

Background Art

An air purifier is a device that can filter out pollutants in the air and purify the air. It inhales air, filters out pollutants such as dust, pollen, bacteria, viruses, harmful gases, and outputs clean air. It is widely used in homes, offices, hospitals, factories and other places.

Air purifiers usually do not require special dust removal. They are designed to directly deal with pollutants in the air. Air purifiers are usually equipped with pre-filters, which can capture large particles of dust and pollutants, such as hair, dust, etc. in indoor air. The pre-filter is generally made of mesh or fiber materials and can be removed by regular cleaning or replacement.

However, when the dust concentration in the environment is high, the filters of the air purifiers in the prior art may be clogged faster because they need to capture more particulate matter and pollutants, which will lead to a decrease in air flow and purification effect and may affect the normal operation of the equipment. Frequent dust cleaning makes the air purifier more troublesome, time-consuming and labor-intensive to use, so it is necessary to propose an air purifier that can automatically remove dust.

In this embodiment, it is convenient to control the operation of the motor 4 through an external control device.

The following is a detailed description of the working principle of the air purifier dust removal device.

When the air purifier body 1 is working, air is taken in and processed from the air inlet, but the air will pass through the transmission frame 2 for dust removal before entering the air purifier body 1. The dust removal process can be controlled by controlling the motor 4 to drive the first bevel gear 20 to rotate, and then drive the second bevel gear 21 to rotate, so that the hollow shaft 15 rotates, and then drives the fan blades 23 to rotate to assist air intake. The dust is blocked by the dust screen 22, but it will adhere to the dust screen 22 due to the action of wind. In this process, the brush 16 rotates with the hollow shaft 15, and then cleans the dust screen 22. The dust after cleaning is raised near the dust screen 22; the rotation of the hollow shaft 15 also drives the cam 18 to rotate, so that it periodically contacts the pad 14. The pad 14 will move to the back of the dust screen 22 when the pressure of the cam 18 is lost under the reset of the spring 13. The upper reset bounces up, thereby realizing reciprocating motion, and drives the piston plate 10 to do piston motion in the dust extraction tube 5 through the sliding rod 12. When the piston plate 10 moves upward, the second one-way valve 9 is turned on, and the first one-way valve 8 is blocked, and air is sucked into the cavity 17 inside the brush 16 through the hollow shaft 15, and then the flying dust is drawn into the dust extraction tube 5 through the through hole. When the piston plate 10 moves downward, the second one-way valve 9 is turned on, and the first one-way valve 8 is blocked, and then the dust extraction tube 5 discharges the dust to the external container containing water to complete the collection, thereby pre-cleaning the dust in an environment with more dust, thereby reducing the load of the air purifier main body 1, thereby increasing the service life of the air purifier main body 1, and at the same time reducing the dust blocking the air inlet, thereby improving the purification effect of the air purifier main body 1.

The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
