Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example 1:
in the present embodiment, the upper portion and the lower portion are defined in the vertical direction in the use state of the oil filter.
As shown in fig. 1 to 2, an oil filter includes a housing 1, a filter element 2 disposed in the housing 1, and a cover body at an upper end of the housing 1. Be equipped with inlet port 3, oil outlet 4 on the lid, the annular cavity between filter core 2 and the shell 1 with inlet port 3 intercommunication, the inner chamber of filter core 2 with oil outlet 4 intercommunication. Oil enters through the oil inlet hole 3, is filtered by the filter element 2 and is discharged through the oil outlet hole 4. The filter element is also the filter material assembly. The general structure and the filtering principle of a shell, a filter element and a cover body belong to the prior art. The invention is mainly improved at the bottom of the oil filter.
The tip is equipped with sensor mounting structure under the shell 1, and sensor mounting structure is including installing guide sleeve 6 and sensor seat 8 in the filter core lower part, and guide sleeve 6 also produces oil chamber intercommunication with the inner chamber of filter core 2, and the cooperation is riveted with the 2 tip pressure of filter core in the upper end of guide sleeve 6, and is equipped with first seal gasket 5 between the two, realizes sealed fixed assembly. The riveting process is the existing process technology.
The upper end of the sensor seat 8 is in sliding sealing fit with the guide sleeve 6, and the lower end is in sealing connection with the housing 1. An O-shaped sealing ring 10 is arranged between the guide sleeve 6 and the sensor seat 8, and two O-shaped sealing rings are arranged. Therefore, the sensor seat and the guide sleeve are arranged in a sliding assembly mode, and a telescopic space is reserved for the filter element.
The lower end of the sensor seat 8 is provided with a mounting groove 9 for mounting the pressure sensor, and the mounting groove 9 is communicated with the inner cavity of the guide sleeve 6. The guide sleeve guides the oil into the mounting groove, and the oil can be detected by a pressure sensor arranged on the mounting groove.
