Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings.

Fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 7, fig. 8, and fig. 9 show an embodiment of a sealing, fixing and connecting structure for a bottle cap and a filter element according to the present invention. Fig. 1 and 2 are perspective views of the same bottle cap from different angles. The embodiment comprises a bottle cap 1 and a filter element 2 which are both plastic parts; the bottle cap 1 comprises a top wall 11 and a side wall 12, a water nozzle 13 is arranged on the top wall 11, internal threads 121 are arranged on the inner surface of the side wall 12, a circumferential enclosure 14 extends downwards on the top wall 11 of the bottle cap 1, the water nozzle 13 is located in an area enclosed by the enclosure 14, a rotation stopping lug 141 and a pull buckle convex rib 142 are arranged on the inner surface of the enclosure 14, the rotation stopping lug 141 is in a strip shape and is axially arranged along the inner surface of the enclosure 14, and the pull buckle convex rib 142 is in a strip shape and is circumferentially arranged along the inner surface of the enclosure 14. In this embodiment, the rotation stopping protrusions 141 are two symmetrically arranged along the circumference, and the pull buckle ribs 142 are three arranged along the circumference and trisected, as shown in fig. 2, such arrangement can balance the stress on the connection between the bottle cap and the filter shell, and certainly, a plurality of rotation stopping protrusions 141 and pull buckle ribs 142 can be provided, and the specific number of the rotation stopping protrusions 141 and the pull buckle ribs 142 can be designed as required. The filter core 2 includes filter media 21 and strains the shell 22, filter media 21 is located and is strained in the shell 22, it is equipped with circular open end 221 to strain the shell 22, and this open end 221 can insert enclose and close 14, be equipped with two of symmetry on this open end 221 outer wall stop groove 2211 with two on the enclosing 14 internal surface stop the cooperation of lug 141, still be equipped with on this open end 221 outer wall and draw and detain slot 2212 with draw and detain protruding muscle 142 cooperation, for making draw detain slot 2212 with draw and detain protruding muscle 142 cooperation smoothness, be an inclined plane in the bottom surface of drawing detaining protruding muscle 142. In this embodiment, the tab groove 2212 is a circumferential groove along the outer wall of the open end 221, but it is also possible to provide three grooves on the circumference of the outer wall of the open end 221 to match the three tab ribs 142 on the inner surface of the enclosure 14, and an O-ring 2213 is further provided on the outer wall of the open end 221 to match the enclosure 14 to seal the open end 221 and the enclosure 14.
