Increasing the structural dynamic stiffness of the air filter is an effective way to reduce radiated noise, which is what we often say is to increase the air filter housing mode. In the prior art, the mode and the dynamic stiffness of the air filter are increased by reducing the radiation noise of the shell, and the main scheme is as follows: (1) increasing the wall thickness of the air filter shell; (2) reinforcing ribs are arranged on the inner wall, the outer wall and the side wall of the shell; (3) improve the shell material. The existing means for improving the air filtering mode can cause the weight and the cost of the air filter to be increased, and in the actual production process, people often want to obtain the maximum structural dynamic rigidity by using lower structural weight, which is also the subject of the utility model.
Disclosure of Invention

In order to achieve the purpose, the utility model adopts the following technical scheme: a structure for increasing the mode of an air filter shell comprises an upper shell, a lower shell and a filter element positioned in the shell, wherein the lower shell is internally provided with a filter cavity communicated with an air inlet pipe, the upper shell is internally provided with an air outlet cavity communicated with an air outlet pipe, and the filter element is fixed in the lower shell to separate the filter cavity from the air outlet cavity; the filter is characterized in that a noise reduction column is designed at a mode weak point of the shell, the noise reduction column penetrates through the filter element to be fixedly connected with the upper shell and the lower shell respectively, a through hole matched with the noise reduction column is formed in the filter element, and a sealing structure is arranged between the through hole and the noise reduction column to ensure that the filter cavity and the air outlet cavity are not communicated with air from the through hole of the filter element.
In one embodiment, the noise reduction column is integrally formed with the upper shell and fixed with the lower shell through screws.
In one embodiment, the noise reduction column is composed of a first noise reduction column and a second noise reduction column, the first noise reduction column is integrally formed with the upper shell, the second noise reduction column is integrally formed with the lower shell, a groove is formed in the surface of the lower shell, and a tapping screw is arranged in the groove to fixedly connect the first noise reduction column and the second noise reduction column.
As a better implementation, the number of the noise reduction columns is 1 to 2, so that the mode of the air filter shell can be enhanced, and the dust holding capacity of the filter element can be considered.
The utility model has the beneficial effects that:
according to the structure for increasing the mode of the air filter shell, the noise reduction column which penetrates through the filter element and is fixedly connected with the upper shell and the lower shell is additionally arranged, so that the mode of the upper shell and the lower shell of the air filter is greatly increased under the condition of slightly increasing the weight, and the radiation noise generated when the air filter works is reduced. The upper shell and the lower shell are fastened by the added noise reduction column through a tapping screw, and the upper shell and the lower shell are easy to operate during installation and disassembly.
Simultaneously, this structure also can strengthen the structural strength of filter core, improves the distribution condition in inside air current field, increases the ash capacity of filter core, prolongs the life of filter core.
