Wherein, the gas holder structure can be regarded as the filter module 1 completes 1 maintenance for every time the dust removal gas is provided for the filter module 1. Preferably, after determining that the engine of the whole vehicle is turned off, the electronic control unit 4 controls the air storage structure 2 to provide the dust removal gas to the filter module 1 for 5 times or more, that is, in each automatic dust discharging process, the air filter performs maintenance for 5 times or more, so as to ensure that the dust in the filter module 1 can be completely discharged.
Further, referring to fig. 6, fig. 6 shows a flowchart 1 of a method of controlling an air cleaner for a vehicle according to an embodiment of the present application, in which the air reservoir structure 2 supplies dust removal gas to the filter module 1.
The gas storage structure 2 comprises a pressure stabilizing valve 24, an electromagnetic valve 25 and a gas storage container 21, the pressure stabilizing valve 24 is arranged on the gas storage container 21, and the electronic control unit 4 controls the gas storage structure 2 to provide dust removal gas for the filtering module 1, and the method comprises the following steps:

Therefore this application is installed air cleaner on the vehicle longeron and has also promoted air cleaner's life to a certain extent.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
