fig. 2 is a partial structural schematic of the present utility model.
Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present utility model, preferred embodiments of the present utility model will be described below with reference to specific examples, but it should be understood that these descriptions are only for further illustrating the features and advantages of the present utility model, and are not limiting the patent claims of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model will be further described with reference to the drawings and preferred embodiments.
Example 1
Referring to fig. 1 and 2, a direct current air filter element according to this embodiment includes a filter cartridge 1, one end of the filter cartridge 1 is provided with an air inlet screen 2, the other end is provided with an air outlet screen 3, a filter rod 4 extending along the axial direction of the filter cartridge 1 is provided between the air outlet screen 3 and the air inlet screen 2, the filter rod 4 includes a stem 41, a cotton sliver 43 with fluff 42 planted on the surface is wound on the stem 41, and the cotton sliver 43 is in a spiral disc and is provided on the stem 41.
Further, the stem 41 has a hollow tubular structure; positioning columns 44 are inserted into two ends of the core column 41 respectively, the positioning column 44 at one end of the core column 41 is connected to the air inlet screen 2, and the positioning column 44 at the other end is connected to the air outlet screen 3.
In this embodiment, unfiltered air enters the filter cartridge 1 along the air inlet screen 2, passes through the filter rods 4 in the filter cartridge 1, and then flows out of the air outlet screen 3 to complete the filtration of the air.
The filter rod 4 adopts a cotton sliver 43 combined structure with the combination surface of the stem 41 and the fluff 42 planted on the combination surface, and the cotton sliver 43 is spirally arranged on the stem 41, so that air passing along the axial direction can effectively contact with the filter rod 4, the filtering time is prolonged, and the filtering effect is improved.
Wherein, through setting up stem 41 to hollow tubular structure, but cooperation both ends cartridge's reference column 44 is used as filter rod 4 location installation use, also prevents to take place the aversion in the use.
Example 2
Referring to fig. 1 and 2, a dc air filter element according to this embodiment is further provided, on the basis of embodiment 1, that one end of the filter cartridge 1 is provided with an air inlet end cap 5 covering the air inlet mesh plate, and the other end is provided with an air outlet end cap 6 covering the air outlet mesh plate.
