When making tea, tea leaves are placed in the filter cartridge, and boiling water is poured into the filter cartridge until the entire cup body is filled. After the tea leaves are soaked for an appropriate time, the filter cartridge is lifted out of the cup body by the handle of the filter cartridge, and the tea water in the filter cartridge flows into the cup body through the mesh holes provided on the bottom and periphery of the filter cartridge under the action of gravity, and the tea leaves remain in the filter cartridge. Since the filter cartridge and the cup cover are separate, when cleaning the tea leaves, the filter cartridge needs to be lifted out by hand and the tea leaves need to be discharged from the filter cartridge. When cleaning the tea leaves, the hand directly contacts the filter cartridge, and the hand and the filter cartridge are easily cross-infected.

[0003] The patent document with publication number CN216221092U discloses a cover for a tea-water separation water cup, which includes a filter core and a filter cover. The filter core and the filter cover are detachably and tightly coupled through thread cooperation. The filter cover is screwed onto the top of the filter core. The cavity formed by the filter core and the filter cover is used to contain tea leaves. The detachable thread coupling can facilitate the placement and cleaning of tea leaf residues. The tight coupling can isolate the top of the warehouse body from the outside air. In this technical solution, when cleaning the tea leaves, the filter core and the filter cover need to be rotated before cleaning the tea leaves. When cleaning the tea leaves, the warehouse body is easily cross-infected with the hand.

[0004] The patent document with publication number CN217243675U discloses a tea filter water cup cover for easy replacement of tea leaves. The cover body is provided with an upper and lower through mounting hole. A tea filter structure is arranged in the mounting hole. The tea filter structure includes a filter cover and a filter cartridge. The filter cover is positioned in the mounting hole through tight fitting or thread sealing. The filter cartridge penetrates the mounting hole and enters the inner cavity of the cup body. The outer wall and the bottom of the filter cartridge are densely provided with filter holes. The lower part of the filter cover is connected with the filter cartridge through a buckle structure. The buckle structure includes a plurality of buckles arranged on the side wall of the filter cover and an L-shaped clamping groove arranged on the opening of the filter cartridge. The buckles and the L-shaped clamping grooves correspond to each other. When the buckles are inserted into the L-shaped clamping grooves, the filter cover can be connected with the filter cartridge by rotating the filter cover. When in the connected state, the filter cover and the filter cartridge can be separated by rotating the filter cover in the opposite direction relative to the filter cartridge. At this time, the filter cover is opened to place or replace the tea leaves. This technical solution also has the problem of cross-infection between the hand and the filter cartridge when placing or cleaning the tea leaves. SUMMARY

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1: Reference Figures 1-4 As shown, a water cup cover that is easy to operate includes a cover body 1, which is threaded and sealed to the upper end of the cup body 2. An inner sleeve 5 is concentrically arranged inside the cover body 1, and a filter cartridge 7 is installed at the lower end of the inner sleeve 5.

[0033] The filter cartridge 7 is concentric with the inner sleeve 5 , and a counterweight 21 is concentrically fixed to the lower end of the filter cartridge 7 .

[0034] A groove 8 is formed on one side of the lower end of the inner sleeve 5 , and a rotating plate 10 is rotatably connected to the groove 8 through a rotating rod 9 . The lower end of the rotating plate 10 is detachably fixedly connected to the upper end of the filter cartridge 7 .

[0035] The upper end surface of the rotating plate 10 is an arc surface, which is concentric with the rotating rod 9. Positioning holes 11 are machined on the upper end of the rotating plate 10 and the end of the rotating plate 10 facing the outside of the filter cartridge 7. The axes of the two positioning holes 11 are perpendicular and pass through the axis of the rotating rod 9. A positioning ball 12 is elastically and slidably connected in the vertical direction within the groove 8 above the rotating plate 10. When the upper end of the filter cartridge 7 contacts the lower end of the inner sleeve 5, the lower end of the positioning ball 12 is located in the positioning hole 11 at the upper end of the rotating plate 10.

[0036] Specifically, the vertical sliding rod 13 is fixed concentrically on the upper end of the positioning ball 12, a vertical hole is formed on the inner sleeve 5 above the groove 8, the vertical hole is communicated with the groove 8, the sliding rod 13 is slidingly inserted into the vertical hole, and the spring 14 is arranged in the vertical hole, the upper end of the spring 14 is fixedly connected with the upper hole wall of the vertical hole, and the lower end of the spring 14 is fixedly connected with the upper end of the sliding rod 13 in the vertical hole.

[0037] The inner edge and the outer edge of the lower end of the inner sleeve 5 are both chamfered. By chamfering the inner edge and the outer edge of the lower end of the inner sleeve 5, the filter cartridge 7 and the rotating plate 10 can be prevented from being hindered by the lower end of the inner sleeve 5 when rotating around the rotating rod 9.

[0038] As shown in Figure 8 When it is needed to open the filter cartridge 7 for cleaning or placing tea leaves, the rotating rod 9 is made to face the left side, and the cover body 1 is swung to the left side, and when the cover body 1 stops moving, the filter cartridge 7 continues to move to the left side under the action of inertia. That is, after the cover body 1 stops moving, the filter cartridge 7 and the rotating plate 10 rotate around the rotating rod 9, the positioning ball 12 exits from the positioning hole 11 on the upper end of the rotating plate 10 when the rotating plate 10 rotates, and after the rotating plate 10 and the filter cartridge 7 rotate by 90 degrees, the positioning ball 12 enters the positioning hole 11 on the outer side of the rotating plate 10, and the positioning ball 12 continues to position the rotating plate 10 and the filter cartridge 7 after entering the positioning hole 11 on the outer side of the rotating plate 10.

When the filter cartridge 7 is opened, the filter cartridge 7 does not need to be touched, and cross infection between the hand and the filter cartridge 7 can be avoided.

[0039] After the tea leaves are placed in the filter cartridge 7, the water cup cover can be swung in the reverse direction, so that the filter cartridge 7 rotates around the rotating rod 9 under the action of inertia, and after the filter cartridge 7 rotates by 90 degrees, the filter cartridge 7 is positioned under the cooperation of the positioning ball 12 and the positioning hole 11 on the upper end of the rotating plate 10. At this time, the upper end of the filter cartridge 7 is in contact with the lower end of the inner sleeve 5, and the filter cartridge 7 is closed. Then, after the cover body 1 is installed on the cup body, tea can be brewed.

[0040] By arranging the counterweight 21 on the lower end of the filter cartridge 7, the inertia of the filter cartridge 7 when the water cup cover is swung can be increased, and the filter cartridge 7 is conveniently opened or closed.

[0041] When the filter cartridge 7 is opened, the inner edge on the upper end of the cup body 2 can also be used to block the filter cartridge 7, and then the filter cartridge 7 can be relatively rotated with the cover body 1 by rotating the cover body 1, so that the filter cartridge 7 is conveniently opened.

[0042] After the tea leaves are placed in the filter cartridge 7, the inner edge of the cup body 2 can also be used to block the filter cartridge 7, and then the filter cartridge 7 can be relatively rotated with the cover body 1 by rotating the cover body 1, so that the filter cartridge 7 is conveniently closed.

The light pole 6 is parallel to the screw rod 4, the screw rod 4 is concentric with the cover 1 and the rotating disc 3.

[0044] Rotating the rotating disc 3 can adjust the height of the inner sleeve 5 and the filter cartridge 7, can separate the tea in the filter cartridge 7 from the water in the cup body 2, and can avoid the tea being soaked in the water in the cup body 2 for a long time.

[0045] Example three: on the basis of example one, referring to Figures 3-7 As shown, the rotating plate 10 is provided with a slot 15 at the lower end, the rotating plate 10 is provided with a reverse L-shaped positioning groove 16 inside above the slot 15, the positioning groove 16 is in communication with the slot 15, and the slot 15 is fixed with an elastic sheet 17 on the vertical groove wall close to the center of the filter cartridge 7.

[0046] The filter cartridge 7 is fixed with an insert 20 corresponding to the slot 15 at the upper end, and the insert 20 is in reverse L shape.

[0047] The insert 20 is pressed against the elastic sheet 17 in the slot 15 and then goes up and enters the positioning groove 16, and after the insert 20 enters the positioning groove 16, the insert 20 is clamped in the positioning groove 16 under the elastic force of the elastic sheet 17.

[0048] A plurality of pin rods 18 are fixed on the part of the rotating plate 10 outside the filter cartridge 7, one end of the pin rod 18 extending towards the center of the filter cartridge 7 extends into the slot 15, and a groove hole 19 corresponding to the pin rod 18 is formed on the outside of the filter cartridge 7, and the part of the pin rod 18 in the slot 15 is inserted into the groove hole 19.

[0049] When the filter cartridge 7 and the rotating plate 10 are connected, the insert 20 is pressed against the elastic sheet 17 in the slot 15, the insert 20 goes up in the slot 15, and at the same time, the filter cartridge 7 is partially dislocated with the pin rod 18 in the slot 15, after the insert 20 is located in the positioning groove 16, the filter cartridge 7 is released, the insert 20 is clamped in the positioning groove 16 under the elastic force of the elastic sheet 17, and the pin rod 18 is inserted into the groove hole 19 of the filter cartridge 7.

[0050] The filter cartridge 7 is convenient to disassemble, and it is convenient to brush the tea stains adhered on the filter cartridge 7.

[0051] Under the insertion cooperation of the pin rod 18 and the groove hole 19 and the insertion cooperation of the insert 20 and the positioning groove 16, when the filter cartridge 7 and the rotating plate 10 rotate around the rotating rod 9, the relative movement of the filter cartridge 7 and the rotating plate 10 can be prevented, and the connection stability of the filter cartridge 7 and the rotating plate 10 is good when the filter cartridge 7 is opened and closed.

[0052] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
