In addition, the first expansion housing is arranged at one side of the main housing, and the air inlet 102 is arranged on the first expansion housing, so that the volume of the housing assembly can be effectively increased when the design height of the housing assembly is smaller, and the calibers of the air inlet 102 and the air outlet 401 can be allowed to be increased, so that the air supply quantity of the air filter can be increased, and the service performance of the air filter can be improved. Moreover, by connecting the first extension case between the upper case 3 and the lower case 1, the first extension case can be prevented from being in a cantilever state, whereby the overall modal performance of the air cleaner can be improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
