Description

Magnetically controlled water cup Field of the Invention The invention relates to the field of daily necessities, especially to a magnetically controlled water cup.

Background to the Invention

In the field of water cups, especially water cups used for making tea, such as business thermos cups, the cup usually has a cup body and a first cup cover, a movable filter screen is set in the cup body. Tea leaves are placed in the cup, tea water is poured into a drinking vessel through a strainer or drunk directly while the tea leaves are kept in the cup body by the filter screen.

Since some kinds of tea leaves are not suitable for long-term steeping, it is necessary to place tea leaves on the filter screen, and then use boiling water to brew the tea leaves. Tea water enters the cup body, and the tea leaves remain on the filter screen. When it is need to drink tea water, lift the filter screen out of the cup body and place it at a proper position, then pour the tea water into a drinking vessel or drink it directly. This way of making tea may be suitable for use in fixed places, people needs to carry it with people, people need to put the filter screen back into the cup body and tighten the first cup cover. When the cup is in a non-upright state, such as when it is tilted or laid flat, tea leaves in the cup are re-infused with tea water. In order to prevent tea leaves from being re-soaked by tea water when the cup is carried around, a tea-separated cup is designed. The cup has a first compartment; a second compartment; and a first cup cover, the first compartment and the second compartment are separated by a valve, Open the valve to make tea water enter the second compartment after tea leaves are brewed in the first compartment, the valve is closed after tea water completely enters the second compartment, so as to isolate tea leaves from tea water and prevent tea leaves from being soaked again.

Statement of the Invention

The present invention aims to provide a magnetically controlled water cup, a valve between a first compartment and a second compartment is opened or closed by changing magnetic poles inside a first cup cover.

Such object is achieved by providing a magnetically controlled water cup as defined in claim 1, 30 further advantageous according to the invention will be apparent from the dependent claims.

The present invention provides a magnetically controlled water cup, the magnetically controlled water cup comprises a cup body and a first cup cover, the cup body comprises a first compartment; a second compartment, and a valve arranged between the first compartment and the second compartment. The first cup cover comprises a first base body that is threadedly fitted with a first cup mouth; a first sealing gasket arranged between the first base body and the first cup mouth; and a first sleeve partially enclosing the first base body. The first sleeve is in clearance fit with the first base body, the first sleeve rotates coaxially relative to the first base body under action of external force. A surface part of the first base body that is joined with the first cup mouth extends coaxially toward an inner cavity of the water cup to form a first protrusion, the first protrusion and the first sleeve form a cavity, the cavity contains a magnet; a rotation shaft partially enclosing the magnet; and a rotation disk meshing and driving with the rotation shaft. The first sleeve is connected with the rotation disk and drives the rotation disk to rotate coaxially, a magnetic pole surface of the magnet is parallel to an axis of the rotation shaft, the rotation shaft is movably connected to the first protrusion, the rotation shaft rotates around its own axis through a meshing transmission of the rotation disk, the axis of the rotation shaft is perpendicular to an axis of the rotation disk Advantageous Effects 1. Magnetic poles are changed by a rotation of a first sleeve, so that a fixed magnetic pole in a cup body is affected by an attractive or repulsive force of a magnet in a first cup cover. In turn, 20 a valve in a cup body can be opened or closed, thereby realizing an effect of separating tea leaves and tea water.

2. Because a magnetic pole surface is parallel to an axis of a rotation shaft and the axis of the rotation shaft is perpendicular to an axis of a rotation disk, a magnet will flip around the axis of the rotation shaft under a rotation of a first sleeve under action of a gear meshing transmission 25 between the rotation shaft and the rotation disk, thereby realizing change of magnetic poles 3 Because flip of a first magnet of the first cup cover causes a first magnetic pole to change, while a second magnetic pole of a second magnet connected to the valve remains unchanged. Therefore, when the first magnetic pole of the first cup cover is different from that of the valve, the valve is attracted by attraction force and the valve opens to separate tea leaves from tea water. When the first magnetic pole of the first cup cover is the same as that of the valve, the valve is affected by repulsive force and the valve is closed to isolate tea leaves and water.

4 Due to limiting effect between a first pillar and first and second walls, the magnetic pole surface is always parallel to a plane of first cup mouth when the first sleeve rotates to a limit position, which maximizes magnetic force between the first cup cover and the valve 5. When the first pillar is attached to the first wall, the first sleeve continues to be rotated to make the first pillar push the first wall, that is, a first base body rotates under push of the first sleeve, so that the first cup cover is screwed to a thread of the first cup mouth. When the first pillar is attached to the second wall, the first sleeve continues to be rotated to make the first pillar push the second wall, that is, the first base body rotates under push of the first sleeve to loosen the first cup cover and separate the first cup cover from the cup body.

6. Since a stationary seat for fixing the magnet adopts an open design, magnetic loss between 10 the first cup cover and the valve is reduced.

7. Because one side of the rotation shaft is driven by a gear meshing, and another side of the rotation shaft is provided with a cylindrical surface in symmetrical position, and the cylindrical surface is slidingly matched with a convex surface of the rotation disk, so when the gear meshing is used for transmission, the rotation shaft can rotate smoothly.

S. Since a bottom of the rotation disk is provided with a spring, under action of elastic force, the rotation disk is closely meshed with the rotation shaft. A cylindrical structure of the rotation disk rotates in an annular groove of the first base body, so the rotation disk does not tilt during rotation process, the rotation shaft and the rotation disk are smoothly meshed for transmission 9. Since a teeth group is provided on the first base body and an elastic element, such as a thin 20 steel sheet or a thin steel wire, is provided on the first sleeve, when the first sleeve is rotated, the thin steel sheet or thin steel wire traverses the teeth group to make sound, which increases interaction between a user and a water cup.

10. When the thin steel sheet or thin steel wire cuts into a gap in the teeth group, the first sleeve is kept at the current rotation angle, so that the magnet is kept at the current position. In particular, the magnetic pole surface of the magnet in the first cup cover is parallel to a plane of the first cup mouth, that is, the rotation disk is maintained at a third rotation angle or a fourth rotation angle, so that the valve in the cup body is continuously opened or closed. When the valve is kept open, brewed tea water in a first compartment can completely flow into a second compartment, in this way, tea leaves are drained to prevent the tea leaves from being soaked in tea water for a long time, which may cause poor taste when re-brewed. When the valve is kept in a closed state, the first compartment is isolated from the second compartment for a long time, so as to keep the tea leaves in a drained state.

11. Due to intermittent distribution of a first lipping and a second lipping, when the first base body is inserted into the first sleeve, the first base body and the first sleeve can be deformed appropriately to smoothly realize smooth buckling of the first lipping and the second lipping.

12. Tea leaves in the first compartment are kept in the first compartment through filtering effect of the filter cartridge, and tea water brewed in the first compartment enters the second compartment through the valve in the filter cartridge, and finally tea water in the second compartment can be conveniently poured out by evacuating the second cup cover for drinking.

Firstly put the rotation shaft 4 into the first groove 14 and the second groove 15 so that the magnetic pole surface of the rotation shaft 4 4 is parallel to the plane of the first cup mouth. Secondly press the rotation disk 5 into the first base body 1 after the third pillar 57 of the rotation disk 5 abuts against the second lug 13 of the first base body 1, and the second pillar 56 of the rotation disk 5 abuts against the first lug 12 of the first base body 1. The teeth portion of the rotation disk 5 meshes with the gear wheel 44 of the rotation shaft 4, such assembly method makes the magnetic pole surface of the rotation shaft 4 in state parallel to the plane of the first cup mouth when the rotation disk 5 is at the third rotation angle or the fourth rotation angle. Therefore, when the first sleeve 3 is rotated to the first rotation angle, the first magnet 40ic pole of the first magnet 40 of the rotation shaft 4 is aligned with the valve 81. When the first sleeve 3 rotates to the second rotation angle, the second magnet 82ic pole 47 of the first magnet 40 of the rotation shaft 4 is aligned with the valve 81.
