The purpose of the utility model can be realized through the following technical scheme:

the utility model provides an air cleaner that filter core was anti-fake, includes casing and the inside filter core of casing, the filter core on be equipped with annular chip, the casing on be equipped with the reader of reading chip information, this reader is connected with the control unit electricity of engine, can send electromagnetic wave signal to annular chip after the reader attach power, annular chip receives the electromagnetism wave back and can feed back filter core information to reader, the reader judges the filter core true and false according to the chip information on the filter core received, perhaps feeds back the engine control unit and then judges the filter core true and false with the chip information received.

Further, the casing including the last casing, barrel and the lower casing that connect gradually, the reader set up on last casing.

Furthermore, the side surface of the cylinder body is provided with an air inlet, and the upper shell is provided with an air outlet.

Furthermore, filter paper is arranged between the shell and the filter element.

Furthermore, the filter element also comprises a filter element main body and an end cover, wherein the end cover is arranged above the filter element main body, and the annular chip is connected with the end cover into a whole.

Furthermore, the filter element also comprises a chip support, the chip support is arranged between the annular chip and the end cover, and the annular antenna is protected from being damaged by extrusion in the injection molding process.

Further, the end cover is connected with the upper shell in a sealing mode.

Further, the end cover is made of polyurethane.

Further, the chip support material is polypropylene.

Further, the information transmission between the reader and the engine ECU or the whole vehicle control unit adopts a CANBUS protocol.

Compared with the prior art, the utility model has the advantages of it is following:

(1) anti-counterfeiting performance: by using the RFID technical scheme, when an error or counterfeit and shoddy filter element product is used, the ECU or the whole vehicle control unit takes corresponding measures to avoid the damage to the engine and effectively protect the rights and interests of consumers;

(2) the chip and the reader are protected by adopting an encryption algorithm technology, and are not easy to be copied and copied;

(3) safe and reliable: the annular chip is injected into the end cover, so that the annular chip is protected from being damaged by external impact in the transportation process or the use process;

(4) the chip support is made of PP materials, so that signals can be prevented from being shielded, and the annular chip can be protected from being extruded during injection molding;

(5) chip theft prevention: the annular chip is injected into the PU end cover, is not easy to be damaged and copied and stolen by other people.

(6) The convenient arrangement: the annular chip adopts the annular design, and the reader can read with the annular chip and be connected in 360 interior optional positions, and the reader does not need special structure location, and the user can rotate the assembly at will when changing the filter core, reduces the use degree of difficulty.
