Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more particularly to a high-efficiency energy-saving filter. Background Art

[0002] The oil used in current cars is generally filtered through a filter, which removes impurities such as dust and tiny metal particles from the oil to protect the engine's operation. Currently used filters are all non-removable sealed structures, so when the filter paper needs to be replaced, the entire filter needs to be replaced, which results in serious waste.

[0003] In the prior art, a Chinese utility model with publication number CN208763797U discloses an environmentally friendly filter. By setting an upper connecting flange and a lower connecting flange, the filter is composed of a detachable upper shell and a lower shell, thereby realizing the detachability of the filter, facilitating the individual replacement of the filter element, and saving costs. However, during the filtering process, since the lower end of the shell is flat, part of the oil is easily retained in the shell, resulting in oil waste. Therefore, the present application proposes a high-efficiency and energy-saving filter. Utility Model Content

[0035] Working principle: When in use, the oil enters the oil inlet 16 through the oil inlet channel 101 and then enters the inner side of the central tube 4, and is filtered through the filter holes 401 and the filter paper 17. The raised portion 602 and the top 603 allow the oil in the central tube 4 and on the filter paper 17 to be discharged as they are tilted, preventing them from being retained in the inner side of the central tube 4. The setting of the inclined port 604 allows the oil at the upper end of the filter element lower cover 6 to be discharged quickly, preventing it from being retained in the filter element structure, thereby reducing oil waste and being more energy-efficient. After the oil is discharged, it is discharged from the oil outlet channel 201 along with the tilt of the annular clamping portion 7 and the inclined surface three 202, so that the oil will not be retained in the bottom shell 2, which can effectively reduce oil waste and be more energy-efficient. When the filter element structure needs to be replaced, only the clamping block 9 needs to be pressed inward so that the clamping block 9 returns to the inner groove 801, and the fixing ring block 8 can be pulled out upward to separate the top cover 1 and the bottom shell 2, so that the filter element structure can be replaced separately, saving more resources and achieving high efficiency and energy saving.
