Therefore, in some embodiments, the second class output module may further receive the operation parameter sent by the remote server, and send the operation parameter to the processing module 111, so that the processing module 111 controls the purifying operation of the purifier according to the operation parameter.

The first type in this embodiment is a type of screen assembly 120 that mates with the body apparatus 110.
If the filter screen assembly 120 installed in the main body device 110 is not the first type of assembly, the working efficiency of the whole purifier may not reach the expected effect, or the user may purchase a fake product, in this embodiment, in order to ensure the purifying effect of the purifier, on the one hand, and reduce the phenomenon that the user is deceptively deceived, when the filter screen assembly 120 which is not the first type is distinguished, the second information will be output.

In some embodiments, screen assembly 120 is generally a consumable assembly where the consumable assembly may create an alternate assembly. In this embodiment, to facilitate remote server updates to the operation and/or operational status of the current purifier, for example, when the service life of screen assembly 120 expires, a user needs to be alerted in time to the replacement. If the usage module detects that a new first type of filter screen assembly 120 is replaced, the output module 114 includes:
and the second class output module is also used for sending the first information to a remote server.
The processing module 111 may match the first information read currently with the first information of the previous filter screen assembly 120 stored in advance in the main device 110, and if the two information are inconsistent, the first information of the currently installed filter screen assembly 120 may be sent to a remote server for the remote server to at least perform tracking service on the filter screen assembly 120. For example, the remote server may send a cleaning prompt or a replacement prompt to the purifier or a control device of the purifier once the screen assembly 120 is in operation.

The processing module 111 in this embodiment may be connected to the remote server through a second type output component, and perform various information interactions with the remote server.
In summary, the output module 114 includes at least one of:

and the second type output module is configured to send second information at least including the first information to a remote server when it is identified that the filter screen assembly 120 is not a filter screen of the first type, where the second information is used to trigger the remote server to send a prompt message to a control device of the purifier when the filter screen assembly 120 is not a filter screen of the first type.
Optionally, the main body device 110 further includes:

In this embodiment, the processing module 111 selects one or more target keys for the present communication from the candidate keys, and determines an encryption algorithm. The encryption algorithm and the target key are components of the encryption parameters.
The encryption algorithm is a functional relation for carrying out data processing on the target key and the first information. The encryption algorithm can be four arithmetic operations such as addition, subtraction, multiplication and division, logical non-logical or logical AND arithmetic, and functional relations formed by different types of arithmetic and/or different types of arithmetic of the same type of arithmetic.
In summary, the target key and the first information may be used as dependent variables of the encryption algorithm, and the independent variables are obtained by calculation, that is, the encrypted information.
In some embodiments, the encryption parameters may include only: one of the encryption algorithm and the target key. For example, when the encryption algorithm is negotiated in advance between the first communication module 113 and the processing module 111, the encryption parameters determined at this time may include only: a target key.
In still other embodiments, the target key may be predetermined negotiated, but the encryption algorithm is dynamically determined. At least one of the encryption algorithm and the encryption key is dynamic, even if an illegal user steals a statically set target key or the encryption algorithm, the encryption algorithm or the target key is dynamic, the communication content between the first communication module 113 and the processing module 111 is still difficult to crack, so that through encryption transmission, the phenomenon that the illegal user intercepts the communication content between the processing module 111 and the first communication module 113 and imitates a legal filter screen assembly based on the intercepted communication content can be reduced, and the problem of identification errors caused by directly stealing first information of a legal manufacturer to write the first information into a second communication module 121 carried by the illegal filter screen assembly 120 after the illegal manufacturer manufactures the illegal filter screen assembly 120 is reduced; thereby improving the anti-counterfeiting capability again.
Optionally, the storage module is specifically configured to store an encryption matrix generated based on a random algorithm; wherein matrix elements in the encryption matrix are the alternative keys.

And selecting a target key from the alternative keys according to the timing result. For example, the timing module counts a predetermined time period, and if the predetermined time period includes N timing units of the timing module, N may be equal to the total number of the candidate keys. For example, when the communication is currently required, and the timing result is detected to be n, the candidate keys ordered as n in the candidate keys can be selected as the target key. And N is a positive integer not greater than N.
Optionally, the screen assembly 120 includes at least one of:
the filtering pore diameter is larger than a first preset value;
the filtering pore diameter is smaller than the second filter screen of the first preset value;

In this embodiment, the first filter may be referred to as a coarse filter, possibly filtering larger filtrate. The second screen may be a fine screen, filtering smaller filters, and typically the first screen and the second screen may be used in combination.
The first type of filter may be a filter that physically cleans by physically intercepting, for example, particulate matter through filter holes. The second type of filter screen is a filter screen which carries liquid or gas participating in chemical reaction and can carry out chemical reaction with a filter object carried in a purified object and filter the object through the chemical reaction.
The screen assembly 120 may be a screen of various shapes, and generally the screen assembly 120 may be a regular or approximately regular shape in shape, which may facilitate production on the one hand and installation and compatibility of different types on the other hand. For example, the screen assembly 120 may be a cuboid or approximately cuboid assembly.
For example, the screen assembly 120 may be approximately rectangular, including: a front face on which the 1 st screen assembly 120 layer is disposed, a back face opposite the front face on which the N-th screen assembly 120 layer is disposed, and 4 sides connecting the front face and the aspects. The second communication assembly may be disposed at any location of screen assembly 120, for example, at a first region of screen assembly 120. The first region is arranged in a region of one of the side surfaces, which is not where the central axis is located. For example, the first region may be disposed in a corner region where two adjacent sides meet, or may be disposed in a center line edge region where one side is offset from the center line of the side. Regardless of where the first region is disposed, or stated, the first region is any region that is offset from the central axis of the screen assembly 120.
In other embodiments, the screen assembly 120 includes: an outer frame and a filter screen assembly 120 layer positioned in the outer frame; the first area may be provided on the front or back of the frame, in addition to the side surface.

The second type of filter screen may be a filter screen in a blacklist, and for the air purifier, the filter screen in the blacklist may not only not achieve the effect of purifying air, but also may release harmful gas due to the material problem of the filter screen assembly 120 itself, and in this embodiment, if the processing module 111 identifies such a filter screen, the execution of the purifying operation of the purifier is prohibited by the execution module, so as to reduce the harm.
The execution module may be located within the main body device 110 and may be directly used to control the cleaning operation of the purifier. For example, the execution module may be a controlled switch, and may control the operation state of the purifier based on the control signal output by the processing module 111. For example, the controlled switch may be a switch such as a transistor or a field effect transistor on a purge control circuit of the purifier, and may control the purifier to enter a purge flow or to close the purge flow by supplying power to the purge circuit.
The execution module may also be a processor like the processing module 111, but corresponds to a different processor than the processing module 111, which is dedicated to controlling the cleaning operation of the purifier.
