[0074] When the tea filter upper cover 31 and the tea filter lower cover 32 are away from each other, a gap will be generated between the two, that is, the non-porous area of the tea filter upper cover 31 and the non-porous area of the tea filter lower cover 32 no longer block the lower cover through hole 321 and the upper cover through hole 311, and the lower cover through hole 321 and the upper cover through hole 311 are both opened, so that the tea brewing area and the separation area are connected. Figure 2 At this time, the liquid container can be Figure 2 As shown, the tea brewing area can be physically located above the separation area, and the water in the tea brewing area can flow into the separation area under the action of gravity and be separated from the tea leaves. When all the water in the tea brewing area enters the separation area, the tea filter upper cover 31 or the tea filter lower cover 32 can be moved again to make the tea filter upper cover 31 close to the tea filter lower cover 32, until the upper cover through hole 311 and the lower cover through hole 321 are blocked again, thereby avoiding the problem of long-term brewing of tea leaves. The liquid container provided by the present disclosure is divided into two spaces by the tea filter assembly, namely the tea brewing area and the separation area.

[0075] The liquid container provided by the present disclosure may include a tea filter assembly 30. The tea filter assembly 30 may include an upper tea filter cover 31 and a lower tea filter cover 32. An upper cover through hole 311 and a lower cover through hole 321 are respectively provided on the upper tea filter cover 31 and the lower tea filter cover 32. The upper cover through hole 311 and the lower cover through hole 321 are staggered. When the upper tea filter cover 31 and the lower tea filter cover 32 are attached to each other, the upper cover through hole 311 and the lower cover through hole 321 are respectively blocked, so that the tea brewing area and the separation area are isolated; when the upper tea filter cover 31 and the lower tea filter cover 32 are spaced apart, both the lower cover through hole 321 and the upper cover through hole 311 are opened, so that the tea brewing area and the separation area are communicated, that is, the tea brewing area and the separation area can be isolated or communicated by attaching or spacing apart the upper tea filter cover 31 and the lower tea filter cover 32.

[0076] As an example, the upper cover through hole 311 may be provided in a first area of the upper tea filter cover 31, and the lower cover through hole 321 may be provided in a second area of the lower tea filter cover 32. The orthographic projection of the first area on the lower tea filter cover 32 does not overlap with the second area. The second area may be a circular area with a radius of R centered at the intersection of the axis of the container body 10 and the lower tea filter cover 32, and the first area may be an annular area with an inner ring radius of R centered at the intersection of the axis of the container body 10 and the upper tea filter cover 31.

[0077] To further improve the sealing performance between the tea brewing area and the separation area and prevent water from overflowing through the gap between the upper tea filter cover 31 and the lower tea filter cover 32 when they are attached to each other, the tea filter assembly 30 may further include a tea filter seal 33.

[0078] Optionally, the tea filter seal 33 may be circular and connected to the bottom wall of the non-hole area of the upper tea filter cover 31. Further, an annular sealing ring 331 protrudes outward from the bottom wall of the tea filter seal 33, and the radius of the annular sealing ring 331 is R. As an example, the tea filter seal 33 may have a fitting surface, and the fitting surface fits on the bottom wall of the upper tea filter cover 31.

[0079] Optionally, the tea filter seal 33 may be annular and connected to the top wall of the non-hole area of the lower tea filter cover 32 (not shown in the figure). Further, an annular sealing ring (not shown in the figure) protrudes outward from the top wall of the tea filter seal 33, and the radius of the annular sealing ring is R. As an example, the tea filter seal 33 may have a fitting surface, and the fitting surface fits on the top wall of the lower tea filter cover 32.

[0080] It can be understood that the connection between the tea filter seal 33 and the upper tea filter cover 31 or the lower tea filter cover 32 can be adhesive bonding, but not limited thereto. The bonding surface of the tea filter seal 33 is provided with a connecting convex portion 332 protruding therefrom. For example, but not limited to, the connecting convex portion 332 is in a T shape, and the small head of the connecting convex portion 332 is connected to the tea filter seal 33. The upper tea filter cover 31 or the lower tea filter cover 32 is provided with a mounting hole matching the connecting convex portion 332, and the large head of the connecting convex portion 332 can be clamped at one end of the mounting hole facing away from the bonding surface, so that the tea filter seal 33 is firmly connected to the upper tea filter cover 31 or the lower tea filter cover 32.

[0081] As an example, the upper tea filter cover 31 can be in a circular sheet shape, the lower tea filter cover 32 is generally cylindrical, and the lower cover through hole 321 can include a cylindrical top wall and a cylindrical side wall. The lower cover through hole 321 can be provided on the cylindrical top wall, but not limited thereto.

[0082] In order to further improve the moving accuracy of the tea filter assembly 30, the tea filter assembly 30 can further include a push rod 34. The push rod 34 extends along the height direction of the container body 10. The upper tea filter cover 31 can be connected to the push rod 34 and move together with the push rod 34. Optionally, the upper tea filter cover 31 can be clamped on the push rod 34 or fixedly connected to the push rod 34.

[0083] The lower tea filter cover 32 is provided with a through hole for the push rod 34 to pass through, and the push rod 34 is slidably connected to the lower tea filter cover 32. In this way, when the push rod 34 moves along the height direction of the container body 10, the upper tea filter cover 31 can move along the height direction of the container body 10 together with the push rod 34 and approach or move away from the lower tea filter cover 32.

[0084] In order to prevent the push rod 34 from accidentally detaching from the lower tea filter cover 32, a fixed plug 36 can be connected to the lower end of the push rod 34. The fixed plug 36 can be clamped on the lower side of the cylindrical top wall of the lower tea filter cover 32. For example, but not limited to, the fixed plug 36 can be a nut.

[0086] The two ends of the tea filter elastic member 35 can respectively abut against the tea filter seal 33 and the cylindrical top wall of the lower tea filter cover 32. In order to reduce the contact between the tea filter elastic member 35 and the tea water and improve the use safety of the liquid container, the tea filter assembly 30 can further include a tea filter sleeve 37. The tea filter sleeve 37 is arranged between the tea filter seal 33 and the lower tea filter cover 32, and the tea filter sleeve 37 has a sleeve top wall, and the sleeve top wall is sleeved on the push rod 34. As an example, the tea filter sleeve 37 can be a circular sleeve.

[0087] The top wall of the cylinder body of the lower tea filter cover 32 is recessed in a direction away from the upper tea filter cover 31 to form an elastic member receiving groove, and the elastic member receiving groove can be circular. The outer diameter of the tea filter sleeve 37 can be equal to the inner diameter of the elastic member receiving groove, and at least a part of the tea filter sleeve 37 is inserted into the elastic member receiving groove, so that a closed space for accommodating the tea filter elastic member 35 is formed by enclosing the top wall of the tea filter sleeve 37 and the top wall of the cylinder body of the lower tea filter cover 32, thereby reducing the contact between the tea water and the tea filter elastic member 35. Both ends of the tea filter elastic member 35 are respectively pressed against the top wall of the sleeve of the tea filter sleeve 37 and the bottom of the elastic member receiving groove.

[0088] In the present disclosure, the push rod 34 can be a stepped rod, and the cross-sectional area of the upper part of the push rod 34 can be larger than the cross-sectional area of the lower part of the push rod 34. A step can be provided between the upper part and the lower part of the push rod 34, and the upper tea filter cover 31 can be arranged at this step. The tea filter elastic member 35 is arranged below the upper tea filter cover 31, and the tea filter elastic member 35 is in a compressed state. Under the elastic force of the tea filter elastic member 35, the upper tea filter cover 31 can be stably clamped at the step and not separated from the push rod 34.

[0089] The tea filter assembly 30 can further include a lower cover sealing ring 38, and the lower cover sealing ring 38 can be sleeved on the outer peripheral surface of the side wall of the cylinder body. When the lower tea filter cover 32 is clamped on the body retaining rib 111, the lower cover sealing ring 38 can be pressed between the body retaining rib 111 and the lower tea filter cover 32, thereby preventing water from flowing through the gap between the body retaining rib 111 and the lower tea filter cover 32.

[0090] Specifically, the container body 10 can have two open ends, which can be a first opening and a second opening respectively. The first opening can be provided with a container lid (not shown in the figure) for the convenience of the user to drink the tea water. The second opening can facilitate the taking and placing of the tea leaves or the tea filter assembly 30.

[0091] Refer to Figures 1 to 2 and Figures 6 to 7, the rotating cover 20 can be used to drive the tea filter upper cover 31 to approach or move away from the tea filter lower cover 32. The rotating cover 20 may include a rotating outer cover 22, a rotating top cover 21, and a rotating inner cover 23. The rotating outer cover 22 may be connected to the second opening of the container body 10.
