The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it is understood that the scope of the present invention is not limited by the specific embodiments. The circulating filter cup of the present invention mainly provides a filter element which is repeatedly pulled up and down in the cup body, so that the liquid in the cup body is repeatedly filtered, thereby improving the purification degree of the liquid. As shown in FIG. 1 , the circulating filter water cup provided by the embodiment is mainly realized by providing the inner tank 2 and the filter element 3 in the cup body 1 . As a preferred embodiment, the water cup further comprises a cover body 5 and an outer wall of the inner liner 2 . The first sealing jaw 4 between the inner wall of the body 1 and, in particular, the inner tube 2 is a cylindrical body that is open at the top and bottom, and is fitted inside the cup 1 and movable up and down. The filter element 3 is disposed at the lower end of the inner liner 2 and moves up and down with the inner tank 2. When the filter element 3 moves up and down with the inner tank 2, the liquid in the cup body 1 is repeatedly filtered through the filter element 3, and the first seal is set.圏4, the liquid flows through the filter element 3 when it is exchanged in the cup 1 with the liner 2. As shown in FIG. 2, in the above solution, a mounting slot 21 is disposed at an outer wall of the lower end of the inner liner 2, and upper and lower edges of the first sealing jaw 4 are correspondingly engaged in the mounting slot 21, and the first sealing port 4 is intermediate The portion protrudes toward the inner wall of the cup, and the protrusion contacts the inner wall of the cup 1. When the inner tube 2 moves up and down, the first sealing jaw 4 slides up and down along the inner wall of the cup 1. Of course, the first sealing jaw 4 can also be set to Other structures, or have a certain elasticity, whose main function is to prevent the liquid from flowing through the filter element 3 when it is exchanged in the cup 1 with the inner liner 2 (see Figs. 3 and 4). The filter body 3 includes a support body 31, a bottom cover 32 and a filter layer 33. The support body 31 is a cover-shaped body of the upper top wall opening 311. The middle portion of the bottom cover 32 defines a through hole 322 and is fastened to the open end of the cover body. The bottom cover 32 is provided with a snap rib 321 on the inner side of the bottom cover 32. The bottom cover 32 is fastened to the open end of the cover by the snap rib 321 , and the filter layer 33 is wrapped in the cavity surrounded by the cover and the bottom cover 32 . The filter layer 33 may be a conventional structure and material. The upper top wall opening 311 and the through hole 322 are channels for the liquid to be exchanged with the cup 1 in the inner liner 2. The whole filter element 3 is set on the lower open end of the inner liner 2, specifically, the lower open end of the inner liner 2 is provided with a support protrusion 22 inwardly, and when the filter element 3 is set inside the lower open end of the inner liner, the bottom cover 32 is spliced to the support. The filter element 3 is prevented from falling off on the bump 22, and the fastening structure of the bottom cover 32 and the support body 31 is provided to facilitate the installation, replacement or cleaning of the filter layer 33. In addition, a second seal is provided between the outer wall of the support body 31 and the inner wall of the inner liner 2 Specifically, a sealing groove mounting groove (not labeled in the drawing) is provided at a corresponding position of the outer wall of the supporting body 31, and the second sealing jaw 6 is sleeved in the sealing jaw mounting groove. In order to smoothly pull the inner liner 2 up and down from the cup body 1, the inner end of the inner liner 2 is provided with a stretching ear 24 (see Fig. 3), and the outer side of the inner ear 2 and the outer wall of the inner liner 2 are opened. (Not shown in the figure), the upper edge of the cup 1 is inserted into the open groove. The water cup provided in this embodiment further includes a cover body 5, the cover body 5 is fastened to the open end of the inner liner 2, and the top surface of the cover body 5 is provided with a rotating edge 51, so that the cover body 5 can be fastened to the open end of the inner liner 2 The cover body 5 is provided with a support edge 52. When the cover body 5 is fastened to the open end of the inner liner 2, the support edge 52 abuts against the upper end surface of the tensioning ear 24, so that the inner liner 2 is pressed by pressing the cover body 5 Push into the cup 1 (see Figure 3). As shown in Figures 3 to 5, when the water cup is specifically used, the inner liner 2 is completely inserted into the cup body 1, and the lid body 5 is unscrewed to hold the liquid in the inner tank 2, such as water, and the cover body 5 is pulled. Pull up the inner tank 2 at the extension of the ear 24 (see Figure 4). The water in the inner tank 2 flows through the filter element 3 through the lower opening 23 of the inner liner into the cup body 1 for the first filtration, and continues to lift the inner liner 2 (such as Fig. 5), the water in the inner tank 2 all enters the cup body 1, and then the lid body 5 is pressed, the lid body 5 drives the inner liner 2 to move downward, and the water in the cup body 1 passes through the inner lower opening 23 through the filter core 3 The second filtration is achieved in the tank 2, and the circulation is repeated several times in this way to increase the degree of purification of the water in the cup and to drink under emergency conditions.
