Description
Technical Field
The utility model relates to a formula environmental protection filter core cut straightly.
Background
The convenience that the user traded the core has been solved to current formula filter core that cut straightly, but is disposable filter core. That is, when the service life of the filter element filter material is finished, the user needs to replace the whole filter element and throw away the filter element shell. This is neither environmentally friendly nor costly to replace.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned prior art not enough, provide a convenient renew cartridge and implement the formula environmental protection filter core that cut straightly that reduces replacement cost.
The utility model discloses a cut straightly formula environmental protection filter core, including the filter core casing, wherein the filter core casing is equipped with the lid that is used for port under the sealed filter core casing, and the surface of filter core casing is equipped with the external screw thread, and the inner wall department of lid is equipped with the internal thread, and the external screw thread meshes with the internal thread mutually, makes the lid fix the lower extreme department at the filter core casing.
Particularly, further, lid inner wall strengthening rib and ring portion, strengthening rib one end is connected in the surface department of ring portion.
And particularly, the reinforcing rib is provided with an installation concave position, and the bottom surface of the filter element shell is propped against the installation concave position.
Particularly, the outer surface of the cover body is uniformly provided with hand-pressing concave positions.
Specifically, the internal thread is located above the reinforcing rib.
Specifically, further, the filter element shell is provided with a step part, and the step part is pressed against the mounting concave position.
The utility model has the advantages that: the filter element shell and the cover body of the structure can be rapidly disassembled or assembled through the external threads and the internal threads, so that the filter element in the filter element shell is convenient to replace, and the replacement cost is further reduced.

The following figures are diagrammatic illustrations: a filter element housing 1; an external thread 101; a step portion 102; a cover body 2; an internal thread 201; a reinforcing rib 202; a mounting recess 203; a ring portion 204; the hand presses the indent 205.
Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 to 4, the utility model discloses a formula environmental protection filter core cut straightly, including filter core casing 1, wherein filter core casing 1 is equipped with the lid 2 that is used for sealed filter core casing 1 lower port, and filter core casing 1's surface is equipped with external screw thread 101, and the inner wall department of lid 2 is equipped with internal thread 201, and external screw thread 101 meshes with internal thread 201 mutually, makes lid 2 fix the lower extreme department at filter core casing 1.
The filter core casing 1 and the lid body 2 of this structure implement quick dismantlement or installation effect through external screw thread 101 and internal thread 201, and the filter core in the filter core casing 1 of being convenient for obtains changing, further reduces the replacement cost.
2 inner wall strengthening rib 202 of lid and ring portion 204, strengthening rib 202 one end is connected in the surface department of ring portion 204 for strengthen the rigidity of lid 2. The reinforcing rib 202 is provided with an installation concave position 203, and the bottom surface of the filter element shell 1 is propped against the installation concave position 203 and used for limiting the position of the filter element shell 1. The outer surface of lid 2 evenly is equipped with hand and presses concave position 205, and hand is pressed concave position 205 and is used for wrench movement lid 2.
The internal thread 201 is located above the bead 202. The filter element shell 1 is provided with the step part 102, and the step part 102 is propped against the mounting concave position 203, so that a twisting space is provided, and the interference twisting is avoided from damaging the external thread 101 or the internal thread 201.
The present invention is not limited to the above preferred embodiments, and any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
