Air purifier

Abstract

The invention provides an air purifier which comprises a base and an outer housing, wherein the base is connected with the periphery of the bottom surface of the outer housing in a supporting manner; an air inlet communicated with a hollow inner cavity is formed in the middle of the bottom surface of outer housing; an air outlet is formed in the upper surface of the outer housing; an inlet filter screen, a filter element, a fan, an outlet filter screen and an air outlet plate are sequentially arranged between the air inlet and the air outlet along the bottom-up circulation direction of air; the inlet filter screen is clung to the air inlet; the outlet filter screen is clung to the lower surface of the air outlet plate; the air outlet plate is arranged at the air outlet; a plurality of air flow through holes distributed uniformly are formed in the air outlet plate; and the air flow through holes are hexagonal. The air purifier has the benefits that the air purification efficiency can be improved; the response time between the filter element and the air is sufficient; the air outlet plate to which settling particles are attached is adopted, so that the sterilization efficiency is high; the impurities in the air are removed effectively; manual cleaning is available; and low carbon and environmental protection are facilitated.

Description

technical field [0001] The invention belongs to the field of air purifier devices, in particular to an air purifier capable of improving purification efficiency. Background technique [0002] Air purifier, also known as air cleaner, refers to the ability to absorb, decompose or transform various air pollutants, such as PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria and allergens, etc., which can effectively improve Air cleanliness; the working principle of the existing air purifier is: the air flows into the air from the air inlet, and after filtering through the filter screen, a filter element is set at the air outlet, such as a plasma generator, and the air outlet is directly contacted by the filtered air to generate plasma. The plasma generated by the device destroys the bacteria, and then releases the purified air from the air outlet; the disadvantage of the existing air evolution device is that the filter element is set too close to the a...

[0002] Air purifier, also known as air cleaner, refers to the ability to absorb, decompose or transform various air pollutants, such as PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria and allergens, etc., which can effectively improve Air cleanliness; the working principle of the existing air purifier is: the air flows into the air from the air inlet, and after filtering through the filter screen, a filter element is set at the air outlet, such as a plasma generator, and the air outlet is directly contacted by the filtered air to generate plasma. The plasma generated by the device destroys the bacteria, and then releases the purified air from the air outlet; the disadvantage of the existing air evolution device is that the filter element is set too close to the air outlet, so that the filter element cannot obtain sufficient response time, and the outlet is missing For the attachment of small particles after reaction in the air, the settled small particles are easily discharged into the air from the air outlet, causing secondary pollution
