The tea making mode is possibly suitable for being used in a fixed place, the filter screen needs to be placed back into the cup body and the cup cover needs to be screwed under the portable application scene, when the cup is in a non-upright state, such as an inclined or flat state, tea leaves in the cup are soaked again by tea water for a long or short time, and when a user of the cup does not notice that the cup is in the non-upright state, the tea leaves in the cup are soaked for a long time, so that the tea water is increased in concentration, and the taste is poor when the tea leaves are directly used next time.

Disclosure of Invention

The invention aims to provide a tea water blending device for a water cup, which is used for separating tea leaves in a tea leaf bin from tea water outside the tea leaf bin by operating the tea water blending device, so that the influence on the drinking taste of the tea water caused by the increase of the concentration of the tea water due to the repeated long-time soaking of the tea leaves in the tea water outside the tea leaf bin is avoided.

Therefore, the invention provides a tea water fusing device for a water cup, which comprises a tea leaf bin for storing tea leaves and a driving unit for driving the tea leaf bin to reciprocate through magnetic force, wherein the tea leaf bin and the driving unit have a certain distance in the magnetic force direction, the tea leaf bin is provided with a first magnet, the first magnet is fixedly connected with the tea leaf bin, the driving unit is provided with a second magnet, the second magnet overturns under the action of external force, and the first magnet and a fourth magnet mutually generate magnetic force action.

Advantageous effects

1. The tea bin is intermittently contacted with the inner bottom of the water cup through the convex part of the tea bin, so that the tea bin is communicated and isolated with the inner part of the water cup, when the convex part of the tea bin is separated from the inner bottom of the water cup, the inner part of the tea bin is communicated with the inner part of the water cup, and boiled water in the water cup enters the tea bin to soak tea. When the interior bottom of bulge butt drinking cup in tealeaves storehouse, the inside in tealeaves storehouse is kept apart with the inside of drinking cup, the boiling water in the tealeaves storehouse continuously soaks tealeaves in order to improve the tea concentration in the tealeaves storehouse, soak the interior bottom that the bulge that makes the tealeaves storehouse through operation drive unit breaks away from the drinking cup after the suitable time, tealeaves storehouse and the inside UNICOM of drinking cup, the inside relatively high tea in concentration in tealeaves storehouse fuses with the outside boiling water in tealeaves storehouse, the interior bottom of bulge butt drinking cup through operation drive unit messenger tealeaves storehouse after the tea fusion of suitable time, the tealeaves storehouse is kept apart with the inside of drinking cup, the concentration of the outside tea in tealeaves storehouse keeps current concentration of drinking.

2. Because the coaxial setting in first storehouse body and the second storehouse body and the third magnet in the first storehouse body is corresponding and the magnetic pole of the opposite face in fourth magnet position in the second storehouse body is opposite, consequently when the first storehouse body and the second storehouse body are close to, third magnet and fourth magnet inter attraction, the first storehouse body and the second storehouse body are through the mutual butt of magnetic force effect, the airtight hookup of the contact surface between the first storehouse body and the second storehouse body is realized to the second sealing washer that the rethread set up between the first storehouse body and the second storehouse body.

3. Under the effect of radial force, radial aversion takes place for first storehouse body and the second storehouse body, because the second storehouse body is inserted to first storehouse body part, consequently, after the inserted portion of first storehouse body contacted the second storehouse body, can not continue to take place the condition emergence of radial aversion in order to avoid the first storehouse body to break away from the second storehouse body between the first storehouse body and the second storehouse body.

4. Because the first storehouse body and the second storehouse body can rotate each other relatively, consequently when radial external force acts on the first storehouse body and the second storehouse body, the two rotates relatively and causes the third magnet in the first storehouse body and the fourth magnet in the second storehouse body to take place the dislocation, the magnetic pole face of third magnet and the magnetic pole face dislocation of fourth magnet, suction between the two weakens or disappears, less axial external force can be with first storehouse body and second storehouse body separately this moment, the two can clear up or change the tealeaves in the tealeaves storehouse after separately.

5. Because the third magnet is embedded into the first lantern ring through interference fit, and the first lantern ring is fastened and sleeved through the interference fit of the first flange and the first main body, the third magnet is relatively fixed and connected with the first main body through the first lantern ring, and the phenomenon that the third magnet is directly connected to the first main body and is not firmly connected due to linear contact of the third magnet and the first main body is avoided. Since the contact type of the cylindrical surface of the first flange and the first cylindrical surface of the first main body is surface-to-surface contact, the first flange is tightly attached to the first cylindrical surface of the first main body under the condition of interference fit.

6. Because the second lantern ring is through interference fit's coaxial cup joint of mode with first main part, and the third step face of the second lantern ring again with first lantern ring butt, consequently can avoid the emergence of the phenomenon that third magnet breaks away from directly after the first blind hole under the extreme atress condition and drops.

7. Because the first lantern ring and the second lantern ring have the same structure, the first lantern ring and the third lantern ring are parts made by the same die, and the die cost is saved and the material management cost is reduced by the arrangement. Because the third lantern ring is in clearance fit with the first cylindrical surface of the first main body, the first lantern ring is also in clearance fit with the first cylindrical surface of the first main body, the third lantern ring is in clearance fit with the first cylindrical surface, the first bin body and the second bin body are in butt joint conveniently, the first flange of the first lantern ring is not affected by the clearance fit of the first lantern ring and the first cylindrical surface, and the first lantern ring and the third lantern ring are two parts which are made by the same die and have the same structure.

8. Likewise, because the second lantern ring and the fifth lantern ring have the same structure, the second lantern ring and the fifth lantern ring are parts made of the same die, and the arrangement saves die cost and reduces material management cost.

9. Because first main part is constructed into the open structure of one end closed other end for tea in the tealeaves storehouse can only pass through same port business turn over, consequently, make the isolation structure in tealeaves storehouse only need in the one end setting in tealeaves storehouse can, simplified isolation structure.

10. Because first lantern ring and second lantern ring all cup joint in first main part, the third magnet imbeds first lantern ring with interference fit's mode, the third step face of third magnet butt second lantern ring, and the fourth column face of the first flange of first lantern ring and second lantern ring respectively with the first cylinder and the second column face interference fit of first main part, consequently under the effect of magnetic force, three interference fit need be overcome if the first blind hole that breaks away from first lantern ring to the third magnet, such setting has improved the life in tealeaves storehouse.

11. The first magnet is embedded into the first end cover in an interference fit mode, so under the action of an external magnetic field, the first magnet drives the first end cover to move, the third lantern ring, the fourth lantern ring and the fifth lantern ring clamp the first end cover, the first end cover drives the fourth lantern ring to move, the fourth lantern ring moves to abut against the inner bottom of the water cup or be far away from the inner bottom of the water cup, and due to the plurality of first through holes formed in the first end cover, when the fourth lantern ring is far away from the inner bottom of the water cup, the interior of the tea leaf bin is communicated with the exterior of the tea leaf bin through the first through holes; when the fourth set of ring supports the interior bottom of water cup, the inside in tealeaves storehouse is kept apart with the outside in tealeaves storehouse.

12. Because first magnet imbeds first end cover with interference fit's mode, the magnetic pole face of first magnet is parallel with the plane of first end cover, consequently, the magnetic pole of first magnet is fixed unchangeable, the transform of outside magnetic pole can be realized under the pivoted condition in external magnetic field, and then produce suction or repulsion force with first magnet, when there is suction between the two, first magnet makes the fourth lantern ring be close to and the interior bottom of butt drinking cup, under the continuous effect of magnetic force, the interior bottom of drinking cup is hugged closely to the fourth lantern ring and then realize inside and the outside isolation in tealeaves storehouse. When repulsive force exists between the first magnet and the second magnet, the fourth sleeve ring is far away from the inner bottom of the water cup by the first magnet, and then the inside of the tea bin is communicated with the outside of the tea bin.

13. Because the fifth step face of the fifth lantern ring and the fifth cylindrical surface of the fourth lantern ring have a height difference in the axial direction, the fifth cylindrical surface protrudes out of the fifth step face, and the fourth lantern ring is made of silica gel or rubber, therefore, when the tea leaf bin contacts or impacts the inner bottom of the cup body, the fifth cylindrical surface of the fourth lantern ring firstly contacts the inner bottom of the cup body, and the hidden danger that the cup body is broken when other parts of the tea leaf bin impact the inner bottom of the cup body is avoided by means of the buffering of the silica gel or the rubber.

The material of the third end cap 46 includes silicone or rubber.

The driving unit 4 works on the principle that rotating the third end cap 46 makes the third end cap 46 drive the second end cap 44 to rotate, because the shaft 435 of the rotating shaft 43 is limited in the third groove 413 of the second body 41, and the second body 41 is fastened and connected with the cup body 2, the second body 41 remains relatively static, the rotating second end cap 44 drives the rotating shaft 43 to turn over through meshing, and then drives the second magnet 323 to turn over, thereby realizing the magnetic field reversal magnetic pole change above the driving unit 4.

The tea leaf chamber 3 operates on the principle that the magnetic pole of the magnetic field of the first magnet 314 toward the driving unit 4 remains unchanged because the first magnet 314 is tightly coupled to the second end cap 44 of the tea leaf chamber 3. When the magnetic pole of the second magnet 323 of the driving unit 4 is the same as the magnetic pole of the first magnet 314 of the tea leaf bin 3, a repulsive force is generated between the two, and the driving unit 4 is fastened and connected with the cup body 2, and the tea leaf bin 3 can freely move in the cup body 2 in the axial direction, so that the first magnet 314 drives the tea leaf bin 3 to be far away from the inner bottom of the cup body 2 under the action of the repulsive force, and the communication between the inside of the tea leaf bin 3 and the inside of the cup body 2 is realized. When the magnetic pole of the second magnet 323 of the driving unit 4 is opposite to the magnetic pole of the first magnet 314, attraction is generated between the two, the first magnet 314 drives the tea leaf bin 3 to be close to and abut against the inner bottom of the cup body 2, and under the continuous action of magnetic force, the fourth collar 326 made of silica gel of the tea leaf bin 3 is tightly attached to the inner bottom of the cup body 2, so that the isolation between the inner part of the tea leaf bin 3 and the inner part of the cup body 2 is realized.

One of the methods for turning over the second magnet 323 in the driving unit 4 of the cup is to place the cup on a plane 3251, such as a table or a palm, hold the cup body 2 with one hand and slightly apply pressure to make the third end cap 46 made of silicone tightly adhere to the plane 3251, so as to generate friction between the third end cap 46 and the plane 3251, and at the same time, rotate the cup body 2, so that the friction between the third end cap 46 and the plane 3251 keeps the third end cap 46, i.e., the second end cap 44 and the plane 3251 relatively stationary, and the cup body 2 drives the second body 41 to rotate relative to the second end cap 44, i.e., the second body 41 drives the rotating shaft 43 to mesh and rotate, thereby finally turning over the second magnet 323, which is suitable for a person with one hand free to operate.

The second method for turning over the second magnet 323 in the driving unit 4 of the cup is to hold the cup body 2 with one hand and rotate the third end cap 46 with the other hand to rotate the second end cap 44 so as to drive the rotating shaft 43 to rotate through the gear 433 meshing, and finally the turning over of the second magnet 323 is realized.
