Detailed Description

For a further understanding of the utility model, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings.

The structure of the present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 6, the pre-filter provided by the embodiment of the utility model comprises a PC plastic cup body 1, a brass head 2 and a filter element liner 3, wherein the PC plastic cup body 1 and the brass head 2 are connected with each other in a threaded manner, a first fixing position 101 for fixing the filter element liner is arranged at the bottom of the inner wall of the PC plastic cup body 1, a second fixing position 201 for fixing the filter element liner is arranged at the top of the inner wall of the brass head 2, and the first fixing position 101 and the second fixing position 201 are in plug-in fit with and closely contact with two ends of the filter element liner 3.
