[0006] In this way, the liquid container provided by the present invention may include a tea filter assembly, and the tea filter assembly may include a tea filter upper cover and a tea filter lower cover, and upper cover through holes and lower cover through holes are respectively arranged on the tea filter upper cover and the tea filter lower cover, and the upper cover through holes and the lower cover through holes are staggered, and when the upper cover cylindrical protrusion is attached to the lower cover cylindrical protrusion, the upper cover through holes and the lower cover through holes are respectively blocked, so that the spaces on both sides of the tea filter assembly are isolated from each other; when the upper cover cylindrical protrusion is separated from the lower cover cylindrical protrusion, the spaces on both sides of the tea filter assembly can be connected through the upper cover through holes and the lower cover through holes.

[0007] In an exemplary embodiment of the present disclosure, the tea filter upper cover further comprises an upper cover ring portion, the annular inner edge of the upper cover ring portion is fixed to the open end of the upper cover cylindrical protrusion, the upper cover through hole is arranged on the upper cover ring portion, and the annular outer edge of the upper cover ring portion fits the inner wall of the container body. In this arrangement, the annular outer edge of the upper cover ring portion fits the inner wall of the container body, which can guide the movement of the tea filter upper cover, prevent the tea filter upper cover from deviating and causing the upper cover cylindrical protrusion to fail to fit with the lower cover cylindrical protrusion, thereby improving the working reliability of the tea filter assembly.

[0008] Furthermore, the tea filter upper cover also includes an upper cover flange, and the upper cover flange extends from the annular outer edge of the upper cover ring portion along the height direction of the container body away from the tea filter lower cover. In this way, the upper cover flange extends from the annular outer edge of the upper cover ring portion along the height direction of the container body, which prevents the annular outer edge from being directly exposed and contacting the inner wall of the container body to cause scratches on the inner wall of the container body, thereby improving the safety of the tea filter upper cover.

[0009] Optionally, one of the upper cover cylindrical protrusion and the lower cover cylindrical protrusion is provided with a clamping rib, and the other is provided with a clamping groove matched with the clamping rib, and when the clamping rib and the clamping groove are clamped in the clamping groove, the upper cover cylindrical protrusion and the lower cover cylindrical protrusion are arranged at intervals.

[0011] Optionally, the cross-sectional area of ​​the bottom end of the cylindrical protrusion of the lower cover is smaller than the cross-sectional area of ​​the open end of the cylindrical protrusion of the lower cover, and the tea filter elastic member is a reset spring, and the bottom end of the reset spring is sleeved on the bottom end of the cylindrical protrusion of the lower cover. In this way, the tea filter elastic member is sleeved on the bottom end of the cylindrical protrusion of the lower cover. On the one hand, the tea filter elastic member is prevented from moving randomly, thereby improving the reliability of the tea filter elastic member. On the other hand, it is easy to assemble, thereby improving the assembly efficiency of the tea filter assembly.

[0012] Specifically, the lower cover through hole includes a lower cover side wall through hole arranged on the cylinder side wall of the lower cover cylindrical protrusion; and / or, the lower cover through hole includes a lower cover bottom wall through hole arranged on the cylinder bottom of the lower cover cylindrical protrusion.

[0013] Furthermore, the liquid container further comprises a tea filter seal, which is sleeved on the outer peripheral wall of the open end of the cylindrical protrusion of the lower cover. In this way, when the cylindrical protrusion of the upper cover is sleeved on the cylindrical protrusion of the lower cover, the tea filter seal is arranged between the through hole of the upper cover and the through hole of the lower cover, thereby further improving the sealing performance of the tea filter assembly.

[0014] According to another exemplary embodiment of the present disclosure, the tea filter lower cover further includes a lower cover body and a lower cover ring portion, the lower cover body is roughly cylindrical, the outer diameter of the lower cover body is larger than the outer diameter of the lower cover cylindrical protrusion, so that the lower cover body is supported on the inner wall of the container body, the lower cover ring portion is annular, and the outer ring edge and the inner ring edge of the lower cover ring portion are respectively fixed to the top of the lower cover body and the opening of the lower cover cylindrical protrusion. In this way, the lower cover body can be supported on the inner wall of the container body, and there is a movable space between the outer diameter of the lower cover body and the outer diameter of the lower cover cylindrical protrusion, so as to facilitate the movement of the tea filter upper cover in the movable space.

In this arrangement, the rotation of the inner cover slides in the internal accommodating cavity along the height direction of the container body to push the tea filter upper cover to move in the height direction of the container body.

[0017] Specifically, the rotating cover also includes a rotating top cover, which is rotatably arranged on the top of the rotating outer cover, and the rotating top cover includes a top cover convex portion, and the bottom surface of the top cover convex portion abuts against the top surface of the rotating inner cover, and the top surface of the rotating inner cover includes an inclined surface, and the rotating top cover is rotated so that the top cover convex portion abuts against different parts of the inclined surface. In this way, the top cover convex portion on the rotating top cover abuts against the inclined surface of the rotating inner cover, and as the rotating top cover rotates, the top cover convex portion abuts against different parts of the inclined surface, thereby pushing the rotating inner cover to move in the height direction of the container body. The circumferential rotation of the rotating top cover is converted into the movement of the rotating inner cover in the height direction of the container body 10, and the structure of the rotating cover provided by the present disclosure is more compact, avoiding taking up too much space.

[0020] Optionally, the elastic member fixing portion is provided with a fixing portion through hole, the fixing portion through hole extends along the height direction of the container body, and the inner cover boss is arranged in the fixing portion through hole. In this way, the internal accommodating cavity can be connected with the tea brewing area through the fixing portion through hole, and the inner cover boss can directly abut against the push rod. In addition, the fixing portion through hole can guide the movement of the inner cover boss, thereby preventing the rotating inner cover from shaking during the movement process, further improving the operating reliability of the rotating cover.

[0021] Furthermore, the outer peripheral wall of the inner cover boss is recessed to form an inner cover ring groove extending along the circumferential direction of the inner cover boss, and the rotating cover further comprises an inner cover sealing ring, which is arranged in the inner cover ring groove and pressed between the inner cover ring groove and the through hole of the fixing part.

[0055] Example embodiments will now be described more fully with reference to the accompanying drawings. However, it should not be understood that the implementation of the present disclosure is limited to the embodiments set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0056] Reference Figures 1 to 5 In one aspect of the present disclosure, a liquid container is provided. The liquid container comprises a container body 10 and a tea filter assembly 30 disposed in the middle of the height direction of the container body 10. The tea filter assembly 30 comprises a tea filter lower cover 32 and a tea filter upper cover 31. The tea filter lower cover 32 is sealed and connected to the inner wall of the container body 10. The tea filter lower cover 32 and the tea filter upper cover 31 respectively comprise a lower cover cylindrical protrusion 325 and an upper cover cylindrical protrusion 315. The upper cover cylindrical protrusion 315 is sleeved on the lower cover cylindrical protrusion 325. The tea filter lower cover 32 and the tea filter upper cover 31 are respectively provided with a lower cover through hole and an upper cover through hole 311, and the lower cover through hole and the upper cover through hole 311 are staggered. The tea filter upper cover 31 can move relative to the tea filter lower cover 32 along the height direction of the container body 10 so that the upper cover cylindrical protrusion 315 and the lower cover cylindrical protrusion 325 are fitted or spaced apart, so that the spaces on both sides of the tea filter assembly 30 can be isolated or connected.

[0057] In this way, the liquid container provided by the present invention may include a tea filter assembly, and the tea filter assembly may include a tea filter upper cover and a tea filter lower cover, and upper cover through holes and lower cover through holes are respectively arranged on the tea filter upper cover and the tea filter lower cover, and the upper cover through holes and the lower cover through holes are staggered, and when the upper cover cylindrical protrusion is attached to the lower cover cylindrical protrusion, the upper cover through holes and the lower cover through holes are respectively blocked, so that the spaces on both sides of the tea filter assembly are isolated from each other; when the upper cover cylindrical protrusion is separated from the lower cover cylindrical protrusion, the spaces on both sides of the tea filter assembly can be connected through the upper cover through holes and the lower cover through holes.

[0058] In an exemplary embodiment of the present disclosure, the tea filter upper cover 31 further includes an upper cover ring portion 314, the annular inner edge of the upper cover ring portion 314 is fixed to the open end of the upper cover cylindrical protrusion 315, the upper cover through hole 311 is arranged on the upper cover ring portion 314, and the annular outer edge of the upper cover ring portion 314 fits the inner wall of the container body 10. In this way, the annular outer edge of the upper cover ring portion fits the inner wall of the container body, which can guide the movement of the tea filter upper cover, prevent the tea filter upper cover from deviating and causing the upper cover cylindrical protrusion to fail to fit with the lower cover cylindrical protrusion, thereby improving the working reliability of the tea filter assembly.

[0059] Furthermore, the tea filter upper cover 31 further includes an upper cover flange 313, which extends from the annular outer edge of the upper cover ring portion 314 along the height direction of the container body 10 away from the tea filter lower cover 32. In this way, the upper cover flange extends from the annular outer edge of the upper cover ring portion 314 along the height direction of the container body 10, which prevents the annular outer edge from being directly exposed and contacting with the inner wall of the container body 10 to cause scratches on the inner wall of the container body 10, thereby improving the safety of the tea filter upper cover 31.

[0060] Optionally, one of the upper cover cylindrical protrusion 315 and the lower cover cylindrical protrusion 325 is provided with a clamping rib, and the other is provided with a clamping groove that cooperates with the clamping rib. When the clamping rib and the clamping groove are clamped in the clamping groove, the upper cover cylindrical protrusion 315 and the lower cover cylindrical protrusion 325 are arranged at intervals. In this way, when the tea filter upper cover 31 moves away from the tea filter lower cover 32 along the height direction of the container body 10, the clamping rib moves close to the clamping groove until the clamping rib is clamped in the clamping groove. This position will be the farthest position of the tea filter upper cover 31 from the tea filter lower cover 32, that is, the travel of the tea filter upper cover 31 is limited by setting the clamping rib and the clamping groove to prevent the tea filter upper cover 31 from being separated from the tea filter lower cover 32.

[0061] As an example, the clamping rib can be provided on the upper cover cylindrical protrusion 315 to form the upper cover clamping rib 312, and correspondingly, the clamping groove can be provided on the lower cover cylindrical protrusion 325 to form the lower cover clamping groove 322. Specifically, the upper cover clamping rib 312 can be provided to protrude from the upper cover cylindrical protrusion 315 along the radial direction of the upper cover cylindrical protrusion 315 and continuously extend along the circumference of the upper cover cylindrical protrusion 315 to form an annular protrusion. In order to further prevent the tea filter upper cover 31 from being separated from the tea filter lower cover 32, a protrusion protruding from the outer wall surface of the lower cover cylindrical protrusion 325 along the radial direction of the lower cover cylindrical protrusion 325 can also be provided above the lower cover clamping groove 322 to further improve the stability of the snap connection, but the present invention is not limited thereto.

[0062] In another exemplary embodiment of the present disclosure, the liquid container further comprises a tea filter elastic member 35, which is pressed between the bottom of the upper cover cylindrical protrusion 315 and the bottom of the lower cover cylindrical protrusion 325. In this way, the tea filter elastic member 35 can provide the upper cover cylindrical protrusion 315 with a force in the direction of the lower cover cylindrical protrusion 325. When the operator removes other external forces, the upper cover cylindrical protrusion 315 will move in the direction away from the cover cylindrical protrusion 325 under the action of the tea filter elastic member 35, so that the upper cover cylindrical protrusion 315 and the lower cover cylindrical protrusion 325, that is, by providing the tea filter elastic member 35, the tea filter upper cover 31 is automatically reset.

[0063] Optionally, the cross-sectional area of ​​the bottom end 324 of the lower cover cylindrical protrusion 325 is smaller than the cross-sectional area of ​​the open end of the lower cover cylindrical protrusion 325, and the tea filter elastic member 35 is a return spring, and the bottom end of the return spring is sleeved on the bottom end 324 of the lower cover cylindrical protrusion 325. In this way, the tea filter elastic member 35 is sleeved on the bottom end 324 of the lower cover cylindrical protrusion 325. On the one hand, the tea filter elastic member 35 is prevented from moving randomly, thereby improving the reliability of the tea filter elastic member 35. On the other hand, it is easy to assemble, thereby improving the assembly efficiency of the tea filter assembly 30.

[0064] Specifically, the lower cover through hole includes a lower cover side wall through hole 321 disposed on the cylinder side wall of the lower cover cylindrical protrusion 325; and / or, the lower cover through hole may include a lower cover bottom wall through hole 323 disposed on the cylinder bottom of the lower cover cylindrical protrusion 325. Figure 3 The cylinder bottom provided in this embodiment can be the upper structure of the upper cover cylindrical protrusion 315 and the upper structure of the lower cover cylindrical protrusion 325, and the lower cover bottom wall through hole 323 can be arranged on the horizontal part of the lower cover cylindrical protrusion 325, but it is not limited to this.

[0065] Furthermore, the liquid container further comprises a tea filter seal 33, which is sleeved on the outer peripheral wall of the open end of the lower cover cylindrical protrusion 325. In this way, when the upper cover cylindrical protrusion 315 is sleeved on the lower cover cylindrical protrusion 325, the tea filter seal 33 is arranged between the upper cover through hole 311 and the lower cover through hole, thereby further improving the sealing performance of the tea filter assembly 30.

[0066] In another exemplary embodiment of the present disclosure, the tea filter lower cover 32 further includes a lower cover body 326 and a lower cover ring 327. The lower cover body 326 is substantially cylindrical, and the outer diameter of the lower cover body 326 is greater than the outer diameter of the lower cover cylindrical protrusion 325, so that the lower cover body 326 is supported on the inner wall of the container body 10. The lower cover ring 327 is annular, and the outer ring edge and the inner ring edge of the lower cover ring 327 are respectively fixed to the top of the lower cover body 326 and the opening of the lower cover cylindrical protrusion 325. In this way, the lower cover body 326 can be supported on the inner wall of the container body 10, and there is a movable space between the outer diameter of the lower cover body 326 and the outer diameter of the lower cover cylindrical protrusion 325, so that the tea filter upper cover can move in the movable space.

[0067] As an example, the inner wall of the middle part of the height direction of the container body 10 is protrudingly provided with a body clip 111, and the lower cover body 326 can be clipped on the body clip 111 to make the connection between the lower cover body 326 and the container body 10 more stable. As an example, the tea filter seal 33 is provided at the connection between the lower cover ring portion 327 and the lower cover cylindrical protrusion 325, but it is not limited thereto.

[0068] Optionally, the liquid container may further include a lower cover sealing ring 38, which may be sleeved on the outer peripheral wall of the lower cover body 326 and pressed between the lower cover body 326 and the inner wall of the container body 10, and the lower cover sealing ring 38 is arranged below the lower cover through hole. This arrangement further improves the sealing performance between the tea filter assembly 30 and the container body 10.

[0069] Further, the liquid container further comprises a rotating cover 20, which may comprise a rotating outer cover 22 and a rotating inner cover 23. The rotating outer cover 22 is fixed to the opening at one end of the container body 10 so that the rotating cover 20 is located on the side of the tea filter upper cover 31 away from the tea filter lower cover 32. The rotating outer cover 22 has an internal accommodating cavity, and the rotating inner cover 23 is slidably arranged in the internal accommodating cavity along the height direction of the container body 10. The bottom end of the rotating inner cover 23 is pressed against the tea filter upper cover 31 to drive the tea filter upper cover 31 to move by the movement of the rotating inner cover 23. In this arrangement, the rotating inner cover 23 slides in the internal accommodating cavity along the height direction of the container body 10 to push the tea filter upper cover 31 to move in the height direction of the container body 10.

[0070] Specifically, the rotating cover 20 also includes a rotating top cover 21, which is rotatably arranged on the top of the rotating outer cover 22. The rotating top cover 21 includes a top cover protrusion 214, and the bottom surface of the top cover protrusion 214 abuts against the top surface of the rotating inner cover 23. The top surface of the rotating inner cover 23 includes an inclined surface. The rotating top cover 21 is rotated so that the top cover protrusion 214 abuts against different parts of the inclined surface.

[0071] In this way, the top cover convex portion 214 on the rotating top cover 21 abuts against the inclined surface of the rotating inner cover 23, and as the rotating top cover 21 rotates, the top cover convex portion 214 abuts against different parts of the inclined surface, thereby pushing the rotating inner cover 23 to move along the height direction of the container body 10. The circumferential rotation of the rotating top cover 21 is converted into the movement of the rotating inner cover 23 along the height direction of the container body 10, and the structure of the rotating cover 20 provided by the present disclosure is more compact, avoiding occupying too much space.

[0072] According to another exemplary embodiment of the present invention, the rotating inner cover 23 is roughly T-shaped, and the rotating inner cover 23 includes an inner cover body 231 and an inner cover boss 233. The inner cover boss 233 is protruded from the bottom surface of the inner cover body 231, and the cross-sectional area of ​​the inner cover boss 233 is smaller than the cross-sectional area of ​​the inner cover body 231. The rotating cover 20 also includes a rotating cover elastic member 26, and the rotating cover elastic member 26 is pressed between the inner cover body 231 and the bottom wall of the internal accommodating cavity; with such a configuration, the rotating cover elastic member 26 is pressed against the inner cover body 231 to avoid accidental separation of the rotating cover elastic member 26 from the inner cover body 231, thereby improving the reliability of the operation of the rotating cover 20.

[0073] Furthermore, the rotating top cover 21 is provided with a top cover clamping portion 211, and the rotating outer cover 22 is provided with an outer cover clamping portion 225 matching the top cover clamping portion 211, and one of the top cover clamping portion 211 and the outer cover clamping portion 225 is a hook, and the other is a convex ring. In this way, the rotating top cover 21 and the rotating outer cover 22 are connected by the hook and the convex ring, which has a simple structure and is easy to assemble.

[0074] Specifically, the bottom wall of the internal accommodating cavity is protrudingly provided with an elastic member fixing portion 223, the rotating cover elastic member 26 is a spring, and the lower end of the rotating cover elastic member 26 is sleeved on the outer periphery of the elastic member fixing portion 223.
