Detailed Description

The following describes the embodiments in further detail with reference to the accompanying drawings.

It will be appreciated by those skilled in the art that while the following description refers to numerous technical details relating to embodiments of the present invention, this is by way of example only, and not by way of limitation, to illustrate the principles of the invention. The present invention can be applied to other fields than the technical details exemplified below as long as they do not depart from the principle and spirit of the present invention.

In addition, in order to avoid limiting the description of the present specification to a great extent, in the description of the present specification, it is possible to omit, simplify, and modify some technical details that may be obtained in the prior art, as would be understood by those skilled in the art, and this does not affect the sufficiency of disclosure of the present specification.

The following describes in detail the preferred embodiments of the present invention with reference to the accompanying drawings.

The utility model has the main characteristics that the ingenious design of filter core, base and container inner spacer connection are in one, have the cross pull rod in the base, and the central point of the cross of pull rod puts a lead screw of design (the effect is through the screw rod fixed top cap). The top cover is provided with a screw port towards the middle. The filter screen is put into top cap and base draw-in groove, fixes through the screw rod.

Fig. 1 is a cross-sectional view showing a filter according to an embodiment of the present invention; fig. 2 is a partial top view illustrating a filter according to an embodiment of the present invention; fig. 3 is a partial bottom view illustrating a filter according to an embodiment of the present invention.

As shown in fig. 1 to 3, the filter according to the embodiment of the present invention mainly includes an upper cover 1, a housing 2, a filter element 3, a partition plate 4, a screw rod 5, a cross rod 6, and a clamping groove 7.

The upper cover 1 is provided with an outlet for fluid/medium to be filtered, the bottom of the shell 2 is provided with an inlet for the fluid/medium to be filtered, the upper cover 1 is tightly connected with the shell 2 through a flange to ensure sealing, a partition plate 4 is transversely arranged on the lower part of the inside of the shell 2, the upper space and the lower space of the partition plate 4 are kept mutually isolated/sealed, the partition plate 4 is provided with a plurality of holes for installing a plurality of filter elements 3, the upper part of each filter element 3 is provided with a top cover, a nut is fixed on the top cover, the bottom of each filter element 3 is embedded and fixed on the partition plate 4 through a clamping groove 7, a screw rod 5 penetrates through the inside of each filter element 3, the lower end of the screw rod 5 is connected with a cross pull rod 6, and the upper. The filter element 3 is internally provided with a filter screen which is fixedly connected with the cross pull rod 6 (or is integrated). In this way, the screen can be detached separately from the body of the cartridge 3 and removed separately.

Thus, when one or more filter element 3 bodies need to be disassembled for replacement, the corresponding filter elements can be integrally disassembled by screwing the clamping grooves 7.
