Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to an anti-counterfeiting structure of a filter screen of an air purifier. Background Art

[0002] The filter is the most core component of air purifier products, but the filter is a component that needs to be replaced regularly. Therefore, the market is flooded with a large number of counterfeit and pirated filter products, which seriously affect the interests of consumers and brand owners. At present, brand owners have various means to prevent counterfeiting of filters, which can be generally divided into physical marks and electronic software. Physical marks include adding QR code anti-counterfeiting, anti-counterfeiting images visible at specific angles, hidden marks on the filter frame, ultraviolet visible, special pattern textures, etc. Electronic software includes encrypted radio frequency identification technology (RFID), embedded electronic chips, electronic tags, development of anti-counterfeiting applets and other anti-counterfeiting means.

[0003] The two types of anti-counterfeiting technologies currently used in filters include physical marking anti-counterfeiting technologies such as adding QR code anti-counterfeiting, visible anti-counterfeiting images at specific angles, hidden marks on the filter frame, visible ultraviolet rays, special pattern textures and other anti-counterfeiting technologies. The main problem is that the anti-counterfeiting level is low and can be easily cracked by bad manufacturers. It is difficult for consumers to distinguish between true and false filters. In terms of electronic software, encrypted radio frequency identification technology (RFID) and embedded electronic chips have good anti-counterfeiting effects, but are often technically complex and costly, which pushes up the cost of the filter and ultimately passes it on to consumers. The present invention provides a low-cost filter structure anti-counterfeiting solution, which has the advantages of simple structure, low cost, and easy identification for consumers.
