In this embodiment, during assembly, the first bevel gear 31 is first mounted on the swinging frame 34, then the swinging shaft 211 of the swinging frame 34 is clamped into the round hole 13 of the upright portion 12 of the screw member 1, then other components of the connecting assembly 3 except the first bevel gear 31, such as the second bevel gear 32, the retainer 33, the swinging frame 34, the torsion spring 35 and the bearing 36, are assembled, after assembly, the retainer 33 is clamped with the screw member 1, and simultaneously the second bevel gear 32 is meshed with the first bevel gear 31, then the main cover 4 is clamped with the screw member 1, and after the main cover 4 is mounted, the annular cover 51 of the assembled control assembly 5 is clamped with the swinging frame 34, thus completing assembly of the cup cover. The parts may be assembled in advance and then assembled.

The working principle of the cup cover of the embodiment is as follows: when the tea leaf 6 needs to be separated from the screw 1, i.e. the tea leaf 6 is soaked, the spherical operating member is operated, the annular cover 51 is rotated, the annular cover 51 is clamped with the swinging frame 34 of the connecting assembly 3, the swinging frame 34 is simultaneously rotated, the second bevel gear 32 fixedly connected with the swinging frame 34 is also rotated, the second bevel gear 32 drives the first bevel gear 31 to rotate, the swinging rod 21 fixedly connected with the first bevel gear 31 is also rotated, the magnet 22 fixedly connected with the swinging rod 21 is rotated, the magnet 22 is rotated from a first position close to the bottom wall of the screw 1 to a second position far away from the bottom wall of the screw 1, the magnetic attraction force of the magnet 22 on the tea leaf 6 is gradually reduced in the process of being far from the bottom wall of the screw 1, after the magnet 22 is rotated by 90 degrees, the magnetic attraction force of the magnet 22 on the tea leaf 6 is smaller than the gravity born by the tea leaf 6, the tea leaf 6 is dropped under the action of gravity, and the tea leaf 6 is separated from the screw 1.

Of course, when the water level in the cup body 7 of the thermos cup is higher, the tea leaf 6 is also subjected to the effect of buoyancy when the water level is completely or partially higher than the tea leaf 6, and at this time, since the tea leaf 6 is already completely or partially in the water, whether the tea leaf 6 is operated at this time or not and whether the tea leaf 6 falls to the bottom of the cup body 7 are not much different. It makes sense if the handling assembly 5 is operated when the water level in the body 7 of the thermos cup is below the tea compartment 6.

In this embodiment, the cup cover can be sold as an independent selling unit, and the tea partition 6, the cup body 7 and the like are selected by a user or a thermos cup manufacturer.

The cup cover provided by the embodiment of the utility model has the beneficial effects that: when the tea partition 6 is needed to be immersed, the control component 5 can be horizontally rotated, the connecting component 3 enables the magnetic component 2 to move, the magnetic component 2 moves from a first position close to the bottom wall of the accommodating cavity 11 to a second position far away from the bottom wall of the accommodating cavity 11, so that the magnetic force on the tea partition 6 is reduced, and when the magnetic force of the magnetic component 2 on the tea partition 6 is reduced to a certain degree, the tea partition 6 falls to the bottom of the cup body 7 under the action of gravity; when the tea infusion partition 6 is not needed, the thermos cup can be inverted, the tea partition 6 falls from the bottom of the cup body 7 to the cup cover direction under the action of gravity, and when the tea partition 6 is attracted by the magnetic assembly 2, the thermos cup is placed in the normal position; the control assembly 5 swings horizontally, unlike the prior art in which it slides horizontally back and forth; the swinging of the magnet 22 along a horizontal axis is also different from the prior art and may result in a smaller magnetic force on the tea leaf 6 when the magnet 22 is in the second position.

Example two

Referring to fig. 10 to 13, the cup cover of the second embodiment is different from that of the first embodiment in that a tea partition 6 is also defined.

In this embodiment, the cup cover further includes a tea partition 6, the tea partition 6 includes a box body 61, a box cover 62, a magnetic member 63 and a sealing member 64, the box body 61 and the box cover 62 are detachably connected, a water passing hole is formed in the box body 61, the magnetic member 63 is fixed on the box cover 62, and the sealing member 64 seals the magnetic member 63.

In this embodiment, the lower surface of the screw member 1 forms a positioning ring portion 15, and the cover 62 forms a positioning ring groove 621 that mates with the positioning ring portion 15.

In other embodiments, the tea leaf 6 may also be made of metal, such as stainless steel, thereby eliminating the weight 65 and seal 64.

The assembly of the cap in this embodiment differs from that of the first embodiment only in that the tea leaf 6 is assembled and the tea leaf 6 is positioned with the screw 1 and magnetically attracted by the two magnets 22.

Referring to fig. 13, the vacuum cup comprises a cup body 7 and a cup cover of the second embodiment, wherein the cup body 7 is provided with internal threads.

The working principle of the thermos cup of the embodiment is as follows: when the tea leaf 6 needs to be separated from the screw 1, i.e. the tea leaf 6 is soaked, the spherical operating member is operated, the annular cover 51 is rotated, the annular cover 51 is clamped with the swinging frame 34 of the connecting assembly 3, the swinging frame 34 is simultaneously rotated, the second bevel gear 32 fixedly connected with the swinging frame 34 is also rotated, the second bevel gear 32 drives the first bevel gear 31 to rotate, the swinging rod 21 fixedly connected with the first bevel gear 31 is also rotated, the magnet 22 fixedly connected with the swinging rod 21 is rotated, the magnet 22 is rotated from a first position close to the bottom wall of the screw 1 to a second position far away from the bottom wall of the screw 1, the magnetic attraction force of the magnet 22 on the tea leaf 6 is gradually reduced in the process of being far from the bottom wall of the screw 1, after the magnet 22 is rotated by 90 degrees, the magnetic attraction force of the magnet 22 on the tea leaf 6 is smaller than the gravity born by the tea leaf 6, the tea leaf 6 is dropped under the action of gravity, and the tea leaf 6 is separated from the screw 1. When the tea partition 6 is not required to be soaked, the vacuum cup is inverted, the tea partition 6 falls down towards the cup cover direction under the action of gravity, the falling speed of the tea partition 6 under the action of buoyancy is not too high, the tea partition 6 can be attracted to the center position of the screw 1 due to attractive force between the magnets 22 (the magnets 22 of the magnetic assembly 2 are reset under the action of the torsion spring 35), and the positioning ring groove 621 of the tea partition 6 can be positioned in the positioning ring part 15 of the lower surface of the screw 1, so that the tea partition 6 is prevented from moving relative to the screw 1. When the tea partition 6 falls in place, the thermos cup is put forward, and the operation is completed.

While the utility model has been described in terms of specific embodiments, it will be apparent to those skilled in the art that the utility model is not limited to the specific embodiments described. Any modifications which do not depart from the functional and structural principles of the present utility model are intended to be included within the scope of the appended claims.
