Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air filters, in particular to an air filter for a forklift and the forklift. Background Art
[0002] The air filter currently used in forklifts has an outer shell comprising a filter housing and a filter cover mounted at one end of the filter housing in the axial direction. The filter element is located in the outer shell. When the filter element needs to be removed, the filter cover needs to be removed horizontally first, and then the filter element can be taken out horizontally. This structure requires a large disassembly space in the horizontal direction. When the engine compartment space is insufficient, the filter housing and filter cover of the air filter need to be removed together before the filter element can be removed. The installation process is the opposite of the disassembly process. Therefore, the loading and unloading operations of traditional air filters are cumbersome, time-consuming and labor-intensive. In addition, this structure makes it difficult to observe and measure the internal structure and dimensions of the filter housing, especially the internal air outlet pipe, thereby affecting the component maintenance process.
