Advantageous effects

1. The magnetic poles are changed through the rotation of the sleeve, so that the fixed magnetic poles in the cup body are under the action of attraction or repulsion of the magnet in the cup cover, and then the valve in the cup body is opened or closed, and the tea and water separation is realized.

2. Because the magnetic pole face is parallel to the axis of the rotating shaft and the axis of the rotating shaft is perpendicular to the axis of the rotating disc, under the gear meshing transmission action of the rotating shaft and the rotating disc, the magnet can turn around the axis of the rotating shaft under the rotation of the sleeve, and further the change of the magnetic pole is realized.

3. Because the magnet of the cup cover is turned over to cause the change of the magnetic pole, and the magnetic pole of the magnet connected with the valve is kept unchanged, when the magnetic pole of the cup cover is different from the magnetic pole of the valve, the valve is under the action of attractive force, the valve is opened, and the tea is separated from the water. When the magnetic pole of the cup cover is the same as that of the valve, the valve is under the action of repulsion force, the valve is closed, and the tea is isolated from the water.

4. Because the first stand and the limiting action of the first vertical wall and the second vertical wall, the magnetic pole surface is always parallel to the plane of the opening part of the cup when the sleeve rotates to the limit position, and the maximization of the magnetic force action between the cup cover and the valve is realized.

5. When the first upright post is jointed with the first vertical wall, the sleeve continues to rotate, the first upright post pushes the first vertical wall, namely the seat body rotates under the push of the sleeve, so that the cup cover is screwed on the thread at the opening part of the cup body. When the first upright post is jointed with the second upright wall, the sleeve continues to rotate, the first upright post pushes the second upright wall, namely the seat body rotates under the push of the sleeve, so that the cup cover is unscrewed, and the cup cover is separated from the cup body.

6. Because the fixed seat for fixing the magnet adopts an open design, the magnetic force loss between the cup cover and the valve is reduced.

7. Because one side of the rotating shaft is in meshing transmission through the gear, the other side of the rotating shaft is symmetrically provided with the cylindrical surface, and the cylindrical surface is in sliding fit with the convex surface of the rotating disc, the rotating shaft can rotate stably during the meshing transmission through the gear.

8. Because the spring is arranged at the bottom of the rotary table, the rotary table is tightly meshed with the rotary shaft under the action of elastic force, and the cylindrical structure of the rotary table rotates in the annular groove of the seat body, so that the rotary table does not incline in the rotating process, and the rotary shaft and the rotary table are stably meshed for transmission.

9. Because the tooth group is arranged on the seat body and the elastic element, such as the thin steel sheet or the thin steel wire, is arranged on the sleeve, when the sleeve is rotated, the thin steel sheet or the thin steel wire passes through the tooth group to make a sound, and the interactivity between a person and a water cup is increased.

10. When the thin steel sheet or the thin steel wire is scratched into the gap in the tooth group, the sleeve can be kept at the current rotating angle, so that the magnet is kept at the current position, particularly the position where the magnetic pole surface of the magnet in the cup cover is parallel to the plane of the opening of the water cup, namely the turntable is kept at the third rotating angle or the fourth rotating angle, and the valve in the cup body is continuously in an opening state or a closing state. When the valve is continuously in the open state, the tea water brewed in the tea bin can completely flow into the tea bin, so that the tea is drained to avoid poor taste when the tea is brewed again due to long-time soaking. When the valve is continuously in the closed state, the tea leaf bin is separated from the tea water bin for a long time, and then the draining state of the tea leaves is kept.

11. Due to the discontinuous distribution of the first lip edge and the second lip edge, when the seat body is inserted into the sleeve, the seat body and the sleeve can be properly deformed, and the first lip edge and the second lip edge can be smoothly buckled.
