Description

Technical Field

[0001] The utility model belongs to the technical field of air purifiers and relates to an air purifier shell and an air purifier. Background Art

[0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to products that can absorb, decompose or transform various air pollutants and effectively improve air cleanliness. Air purifiers are mainly composed of motors, fans, air filters and other systems. Their working principle is: the motor drives the fan to rotate to circulate the air, and various pollutants are filtered out or absorbed after passing through the air filter. The filtered clean air is then discharged out of the machine.

[0003] Some existing air purifiers use side air outlets for air outlet. For example, the utility model patent with application number CN202321965618.2 provides an air purifier, including: an outer shell body, a first air outlet is arranged on one side of the outer shell body, and a first air inlet is arranged on the other two sides of the outer shell body; an inner shell body, the inner shell body is arranged in the outer shell body, a gap is arranged between the inner shell body and the outer shell body, a second air outlet is arranged on the side of the inner shell body opposite to the first air outlet, a second air inlet is arranged on the side of the inner shell body opposite to the first air inlet, and a filter element installation cavity is arranged outside the second air inlet; at least one filter element, the filter element is arranged in the filter element installation cavity; an air guide mechanism, the air guide mechanism is arranged in the inner shell body; wherein, under the action of the air guide mechanism, the air entering the first air inlet passes through the filter element, the second air inlet, and the second air outlet in sequence, and is discharged from the first air outlet.

[0004] In summary, although some existing technical solutions reduce the dust accumulation in the filter chamber by setting the air outlet on the side of the shell body, since the air outlet is a normally open structure, dust can still enter the filter chamber through the air outlet, and there is much room for improvement.
