Description

Technical Field

[0001] The present application relates to the field of cups, and in particular to a cup cover and a tea brewing cup. Background Art

[0002] A tea brewing cup is a cup used for brewing tea in daily life. In order to improve the convenience of brewing tea, a tea compartment is usually placed in the cup, and tea leaves are placed in the tea compartment to brew tea. However, after the tea leaves are placed in the tea compartment of the tea brewing cup, they are soaked in water for a long time, and the concentration of the tea cannot be well controlled. Long-term soaking is likely to affect the taste of the tea.

[0003] In order to improve the problem of poor control of tea concentration, there are some tea-brewing cups with tea-water separation structures on the market. A magnetic attraction structure and a switch are set on the cup lid of the tea-brewing cup, and a tea compartment that can be magnetically attracted to the magnetic attraction structure is placed in the tea-brewing cup. When in use, the tea compartment is magnetically attracted to the cup lid by turning the cup over, thereby separating the tea compartment from the tea. When it is time to brew tea, the switch on the cup lid is rotated to cancel the magnetic attraction between the cup lid and the tea compartment, and tea can be brewed again.

[0004] However, for some larger tea cups, a tea cup filled with water has a certain weight, and it is not easy to flip the tea cup, which reduces the convenience of using the tea cup. Therefore, the applicant proposes a tea cup with a traction mechanism, which controls the tea compartment by winding the traction belt of the traction mechanism. When it is not necessary to make tea, the traction belt is rolled up along the cover body, so that the tea compartment is separated from the tea; when it is necessary to make tea again, the traction belt is unwound along the cover body, so that the tea compartment falls into the tea and continues to make tea.

[0062] The implementation principle of Example 3 is as follows: by rotating the rotating button 72 on the top of the cover body 2, the rotating button 72 drives the rotating part 76 to rotate, and the rotating part 76 reels or unwinds the connecting belt 77. Under the traction of the connecting belt 77, the movable pulley group is driven to move along the horizontal direction of the cup cover base 1, so that the traction belt 8 can be quickly unwound or reeled under the moving traction of the movable pulley group and the fixed traction of the fixing part.

[0063] Example 4

[0064] The difference between Example 4 and Example 1 is that, see Figure 4 , the driving member is installed on the top of the cover body 2, specifically, the driving member includes a rotating button 72, the connecting member includes a rotating portion 76 and a connecting belt 77, the bottom of the rotating portion 76 is rotatably connected to the top of the cup cover base 1, one end of the connecting belt 77 is fixedly connected to the rotating portion 76, and the end of the connecting belt 77 away from the rotating portion 76 is connected to the movable pulley group, and a mounting hole 21 is opened on the side of the cover body 2, and the mounting hole 21 is opened corresponding to the movement direction of the movable pulley group.

Under the traction of the connecting belt 77, the movable pulley group is driven to move along the horizontal direction of the cup cover base 1, so that the traction belt 8 can be quickly unwound or reeled under the moving traction of the movable pulley group and the fixed traction of the fixing part.

[0066] Example 5

[0067] The difference between Example 5 and Example 1 is that, see Figure 5, the driving member is arranged at the top of the cover body 2, specifically, the driving member includes a lifting portion 73, the connecting member includes a connecting belt 77, a limiting frame 771 is fixedly arranged on the top of the cup cover base 1, one end of the connecting belt 77 is connected to the movable pulley group, a mounting hole 21 is opened on the top of the cover body 2, one end of the connecting belt 77 away from the movable pulley group is passed through the limiting frame 771, and is passed through the cover body 2 and then connected to the lifting portion 73, a fixing seat 22 is fixedly arranged on the top of the cover body 2, and the lifting portion 73 can be sleeved and connected to the fixing seat 22, and the rest is the same as Example 1.

[0068] The implementation principle of Example 5 is as follows: manually apply external force to lift the lifting part 73 on the top of the lid body 2, and the lifting part 73 drives the movable pulley group to move along the horizontal direction of the cup lid base 1, so that the traction belt 8 can be quickly unwound or reeled under the moving traction of the movable pulley group and the fixed traction of the fixing part; when the traction belt 8 is in the reeled state, the lifting part 73 is mounted on the fixed seat 22 to play the role of fixing the reeled state of the traction belt 8. When the traction belt 8 is in the unwinding state, the lifting part 73 is away from the fixed seat 22 and abuts against the top of the lid body 2, which has a better positioning effect.

[0069] Example 6

[0070] The difference between Example 6 and Example 1 is that, see Figure 6 The driving member is arranged at the top of the cover body 2. Specifically, the driving member includes a pressing portion 74. A movable hole 23 is opened at the top of the cover body 2. The pressing portion 74 is movably installed in the movable hole 23. Preferably, the pressing portion 74 is an "I"-shaped pressing block. The connecting member includes a sliding platform 78. The sliding platform 78 is installed on the movable pulley group. Specifically, the sliding platform 78 is fixedly connected to the sliding member 11. The sliding platform 78 is provided with an inclined surface 781. The inclined surface 781 is inclined corresponding to the horizontal plane of the movable pulley group. The bottom of the pressing portion 74 slides and abuts against the inclined surface 781.

[0071] Furthermore, a reset mechanism is provided at the top of the cup cover base 1 to reset the stroke amplification mechanism. Specifically, the reset mechanism is a reset spring 15. A spring fixing block 151 is fixedly provided at the top of the cup cover base 1 at a position close to the side of the movable pulley group. One end of the reset spring 15 is connected to the spring fixing block 151, and the end of the reset spring 15 away from the spring fixing block 151 is connected to the movable pulley group, specifically, the sliding member 11 installed on the movable pulley group.

[0072] The implementation principle of Example 6 is as follows: when the pressing portion 74 is pressed, the pressing portion 74 moves downward and slides along the inclined surface 781 of the sliding platform 78. Since the pressing portion 74 does not move in the horizontal direction, the pressing portion 74 pushes the sliding platform 78 to move, thereby driving the movable pulley group to move in the horizontal direction of the cup cover base 1 away from the fixed pulley 32, so that the traction belt 8 is wound. When the traction belt 8 is wound, the return spring 15 accumulates elastic force, and the top of the pressing portion 74 abuts against the top of the cover body 2. It plays a positioning role; when the pressing portion 74 moves upward, the pressing portion 74 returns to its initial state, canceling the abutment with the inclined surface 781 of the sliding table 78, and under the action of the return spring 15, the return spring 15 releases the elastic force, so that the movable pulley group moves in the horizontal direction of the cup cover base 1, close to the movable pulley 30, so that the traction belt 8 is unwound. When the traction belt 8 is unwound, the return spring 15 returns to its initial state, and the bottom of the pressing portion 74 abuts against the inclined surface 781 of the sliding table 78.

[0073] Example 7

[0074] The difference between Example 7 and Example 1 is that, referring to Figure 7 and Figure 8 The stroke amplification mechanism includes a gear structure 4, which includes an outer gear ring 40, an inner gear ring 41, a first transmission gear 42, a second gear ring 44 and a second transmission gear 45. The outer gear ring 40, the inner gear ring 41, the second gear ring 44 and the second transmission gear 45 are respectively rotatably carried on the cup cover base 1, the first transmission gear 42 is rotatably carried on the cup cover base 1, and the first transmission gear 42 is meshedly connected between the outer gear ring 40 and the inner gear ring 41, the second gear ring 44 and the second transmission gear 45 are rotatably carried on the cup cover base 1, and the second transmission gear 45 is meshedly arranged between the second gear ring 44 and the inner gear ring 41. In this embodiment, the outer gear ring 40 is used as the driving mechanism 7, and the outer gear ring 40 or the inner gear ring 41 is driven to rotate by manually rotating the driving mechanism 7. The rotation directions of the outer gear ring 40 and the inner gear ring 41 are opposite, and a fixing pin 49 is arranged on the outer gear ring 40. The fixing pin 49 can be set as a component such as a penetration rod for fixing the fixed end of the traction belt 8. When the outer tooth ring 40 is rotated and carried on the cup cover base 1, the penetration rod faces the upper surface of the cup cover base 1 and is connected to the fixed end of the traction belt 8. At the same time, a first guide winding member 43 is provided on the inner tooth ring 41. The first guide winding member 43 is located between the penetration hole 14 and the fixed end of the traction belt 8. The first guide winding member 43 can be set as a first guide rod or the like for guiding the traction belt 8 located between the penetration hole 14 and the penetration rod to be wound along the inside of the cup cover base 1. A second guide winding member 46 is provided on the second tooth ring 44. The second guide winding member 46 is located between the penetration hole 14 and the first guide winding member 43, and can drive any point of the traction belt 8 between the penetration hole 14 and the first guide winding member 43 to move away from the first guide winding member 43.

[0075] The outer gear ring 40 and the inner gear ring 41 cooperate in the following manner: Figure 7 The outer gear ring 40 is covered on the inner gear ring 41, and the outer gear ring 40 is rotatably connected to the cup cover base 1, which reduces the probability of jamming when the outer gear ring 40 and the inner gear ring 41 rotate due to the gap between the outer gear ring 40 and the inner gear ring 41, causing foreign matter to enter between the inner gear ring 41 and the outer gear ring 40 along the gap.

[0076] The cup cover base 1 is provided with a positioning mechanism for limiting the movement of the gear structure 4 and / or the driving mechanism 7. The positioning mechanism limits the movement of the inner gear ring 41 and the outer gear ring 40. The positioning mechanism can be a snap-on, lock-on or magnetically attracted method to limit the movement of the gear structure 4 and / or the driving mechanism 7. When the inner gear ring 41 and the outer gear ring 40 move to a certain extent in opposite directions, that is, when the free end of the traction belt 8 approaches the cup cover base 1 to a certain extent, the positioning mechanism limits the inner gear ring 41 and the outer gear ring 40 to continue to rotate or rotate in the opposite direction, so that the traction belt 8 is contracted to a specific length and cannot continue to move away from or close to the cup cover base 1.

[0077] Reference Figure 8 In this embodiment, the first positioning member 18 is disposed on the cup cover base 1, the second positioning member 34 is disposed on the outer gear ring 40, and the first positioning member 18 and the second positioning member 34 are magnetically matched.

[0078] Reference Figure 7 and Figure 8 A winding radius limiting member 16 is provided on the cup cover base 1 between the penetration hole 14 and the fixed pin 49. The winding radius limiting member 16 here can be two limiting rods. The two limiting rods are provided between the penetration hole 14 and the fixed pin 49, and on the cup cover base 1 near the fixed pin 49, a gap is formed for the traction belt 8 to pass through. The fixed end of the traction belt 8 is movably penetrated through the winding radius limiting member 16 and connected to the fixed pin 49.

[0079] The implementation principle of Example 7 is as follows: when the outer gear ring 40 or the inner gear ring 41 is driven to rotate by the driving mechanism 7, the outer gear ring 40 and the inner gear ring 41 rotate in opposite directions along the first transmission gear 42 respectively, and the through-rod drives the fixed end of the traction belt 8 to rotate along with the outer gear ring 40, and at the same time, the first guide rod drives the traction belt 8 to rotate in the opposite direction to the fixed end of the traction belt 8, and the traction belt 8 is wound twice in different directions in the cup cover base 1 at the same time, so that the distance moved from the free end of the traction belt 8 to the cup cover base 1 is greater than the driving mechanism 7. The purpose of driving the outer gear ring 40 or the inner gear ring 41 to rotate is to facilitate the rapid pulling of the traction belt 8 to the cup lid base 1; when the free end of the traction belt 8 is close to the cup lid base 1, the first positioning member 18 and the second positioning member 34 can be magnetically engaged, thereby limiting the inner gear ring 41 or the outer gear ring 40 from continuing to rotate; the winding radius limiting member 16 is used to limit the winding radius of the fixed end of the traction belt 8 carried by the fixed pin 49 along the cup lid base 1, so that the fixed end of the traction belt 8 is wound within the range limited by the winding radius limiting member 16.

[0080] Example 8

[0081] The difference between Example 8 and Example 1 is that, referring to Fig. 9 , the stroke amplification component 62 includes a connecting rod structure 5, the cross section of the cup cover base 1 is circular, the traction belt 8 is movably arranged on the cup cover base 1, and the cup cover base 1 is vertically provided with a hole for the traction belt 8 to pass through. The upper end of the traction belt 8 passes through the cup cover base 1 upward and is fixedly connected to the upper surface of the cup cover base 1, so that the traction belt 8 passes through the upper end of the cup cover base 1 and is close to the upper surface of the cup cover base 1. At the same time, the traction belt 8 is passed through the connecting rod structure 5. The connecting rod structure 5 is arranged on the upper surface of the cup cover base 1 to amplify the stroke of the traction belt 8. The traction belt 8 is connected to the connecting rod structure 5. The driving mechanism 7 is movably connected to the cup cover base 1 to drive the connecting rod structure 5 to move so as to reel or unreel the traction belt 8, and the stroke amplification is realized during the reeling or unreeling process. It should be noted that the input stroke of the driving mechanism 7 to the connecting rod structure 5 is smaller than the output stroke of the traction belt 8 to realize the stroke amplification.

[0082] Reference Fig. 9 The connecting rod structure 5 includes a pull block 51, a connecting rod 52 and a guide component 53. The pull block 51 is arranged in a vertical block shape. The pull block 51 is horizontally slidably connected to the upper surface of the cup cover base 1. One end of the pull block 51 is movably sleeved on the traction belt 8, one end of the connecting rod 52 is rotatably connected to the driving mechanism 7, and the other end of the connecting rod 52 is rotatably connected to the end of the pull block 51 away from the traction belt 8. The guide component 53 is fixedly arranged on the cup cover base 1 and is located on the side of the traction belt 8 for guiding the movement of the pull block 51, and the guiding direction of the guide component 53 to the pull block 51 intersects with the moving direction of the driving mechanism 7, and the connecting rod 52 intersects with the straight line where the moving direction of the driving mechanism 7 is located.

[0083] When the driving mechanism 7 moves toward the direction approaching the pulling block 51, the driving mechanism 7 drives the pulling block 51 to move toward the side of the length direction of the traction belt 8 through the connecting rod 52, and the guide component 53 guides the movement of the pulling block 51. The movement of the pulling block 51 drives the traction belt 8 to be reeled. At this time, the reeling length of the traction belt 8 is greater than the moving distance of the driving mechanism 7, thereby realizing the stroke amplification function of the traction belt 8 during the reeling process; when the driving mechanism 7 moves toward the direction away from the pulling block 51, the driving mechanism 7 drives the pulling block 51 to move and reset through the connecting rod 52, and the guide component 53 guides the movement and reset of the pulling block 51. The resetting movement of the pulling block 51 drives the traction belt 8 to be unreeled. At this time, the unreeling length of the traction belt 8 is also greater than the moving distance of the driving mechanism 7, thereby realizing the stroke amplification function of the traction belt 8 during the unreeling process.

[0084] Reference Fig. 9 , one end of the connecting rod 52 is sleeve-connected with the driving mechanism 7, and the other end of the connecting rod 52 is sleeve-connected with the pulling block 51. In this embodiment, a first sleeve 720 is vertically fixedly provided at one end of the connecting rod 52, and at the same time, the driving mechanism 7 includes a vertically provided first sleeve column 710, and the first sleeve 720 is rotatably sleeved on the first sleeve column 710 to realize the rotational connection between the connecting rod 52 and the driving mechanism 7; a second sleeve 721 symmetrical to the first sleeve 720 is vertically fixedly provided at the other end of the connecting rod 52, and a second sleeve column 722 is vertically fixedly provided at one end of the pulling block 51 away from the traction belt 8, and the second sleeve 721 is rotatably sleeved on the second sleeve column 722 to realize the rotational connection between the connecting rod 52 and the pulling block 51. In other embodiments, a third sleeve column may be provided at one end of the connecting rod 52, the driving mechanism 7 includes a third sleeve, and the third sleeve is rotatably sleeved on the third sleeve column to realize the rotational connection between the connecting rod 52 and the driving mechanism 7; a fourth sleeve column may be provided at the other end of the connecting rod 52, the pull block 51 is provided with a fourth sleeve, and the fourth sleeve is rotatably sleeved on the fourth sleeve column to realize the rotational connection between the connecting rod 52 and the pull block 51. In addition, the rotational connection can also be realized by hingedly connecting the two ends of the connecting rod 52 to the driving mechanism 7 and the pull block 51, as long as the rotation function is realized, which will not be described in detail here.

[0085] Reference Fig. 9, the guide component 53 is set as a guide rail structure, the length direction of the guide rail structure intersects with the moving direction of the driving mechanism 7. In this embodiment, the length direction of the guide rail structure is perpendicular to the moving direction of the driving mechanism 7. Specifically, the guide component 53 includes two guide plates 531 arranged in parallel and spaced apart. The two guide plates 531 are fixedly arranged on the upper surface of the cup cover base 1 and are located on the same side of the traction belt 8. There is a gap between the two guide plates 531 for the pull block 51 to move. The end of the pull block 51 away from the traction belt 8 faces the two guide plates 531 and penetrates into the gap between the two guide plates 531. The length direction of the guide plate 531 intersects with the moving direction of the driving mechanism 7, so that the movement of the pull block 51 can pull the traction belt 8 to be wound or unwound. In other embodiments, the guide component 53 can also be set as a sliding seat, the length direction of the sliding seat intersects with the moving direction of the driving mechanism 7, and the pull block 51 is sleeved and slid on the sliding seat along the length direction of the sliding seat to guide the movement of the pull block 51. No further description is given here.

[0086] The number of connecting rod structures 5 in this embodiment is set to two groups, and the two groups of connecting rod structures 5 are respectively located on both sides of the traction belt 8. The traction belt 8 passes through the pull block 51 in each group of connecting rod structures 5 in sequence, and one end of each group of connecting rods 52 is respectively rotatably connected to the driving mechanism 7, so that the driving mechanism 7 can drive the two connecting rod structures 5 to move at the same time. The guide plates 531 in the two groups of connecting rod structures 5 are arranged in parallel, and the parts where the two groups of connecting rods 52 are rotatably connected to the driving mechanism 7 are arranged in an up-and-down stacking arrangement. Specifically, the two first sleeves 720 in the two groups of connecting rod structures 5 are arranged in an up-and-down stacking arrangement on the first sleeve column 710. The two groups of connecting rod structures 5 form a group of connecting rod stroke amplification units 50, and the connecting rod stroke amplification units 50 are arranged in a plurality of groups, and the plurality of connecting rod stroke amplification units 50 are arranged at intervals along the moving direction of the driving mechanism 7. In this embodiment, three groups of connecting rod stroke amplification units 50 are arranged.

[0087] In this embodiment, the driving mechanism 7 is arranged on the top of the cover body 2, and the driving mechanism 7 drives the connecting rod structure 5 to reel or unreel the traction belt 8 by pushing and pulling. Specifically, the driving mechanism 7 also includes a hand-held portion 711 and a connecting support portion 719 connected to each other. The hand-held portion 711 is inserted through the cover body 2 so that the user can drive the driving mechanism 7 through the hand-held portion 711. The connecting support portion 719 is slidably connected to the cup cover base 1 to drive the traction belt 8 to amplify the stroke.

[0088] Reference Fig. 9The positioning mechanism includes a first positioning member 18 and a second positioning member 34. The first positioning member 18 is arranged on the cover body 2, and the second positioning member 34 is fixedly arranged on the connecting support portion 719. When the driving mechanism 7 drives the connecting rod structure 5 to complete the winding of the traction belt 8, the first positioning member 18 and the second positioning member 34 are correspondingly arranged and connected by magnetic attraction. In this embodiment, the first positioning member 18 and the second positioning member 34 are preferably magnetic members.

[0089] Reference Fig. 9 In this embodiment, the hand-held portion 711 is vertically arranged, the connecting support portion 719 is horizontally arranged, the lower end of the hand-held portion 711 is fixedly connected to the connecting support portion 719, and the hand-held portion 711 is vertically penetrated through the cover body 2, and the upper end of the hand-held portion 711 is penetrated from the top of the cover body 2. At the same time, the cover body 2 is provided with a first avoidance groove 24 along the length direction of the connecting support portion 719 for the hand-held portion 711 to move toward or away from the first positioning member 18.

[0090] The implementation principle of Example 8 is as follows: the driving mechanism 7 moves toward the direction approaching the pulling block 51, and the driving mechanism 7 is connected to the three groups of connecting rod stroke amplification units 50 through three first sets of columns 710 respectively. In each group of connecting rod stroke amplification units 50, the first set of columns 710 moves with the movement of the driving mechanism 7, and the moving first set of columns 710 drives the two pulling blocks 51 to move in opposite directions through two connecting rods 52 respectively, and the two pulling blocks 51 simultaneously drive the traction belt 8 to be reeled in. A total of six pulling blocks 51 in the three groups of connecting rod stroke amplification units 50 synchronously reel in the traction belt 84, thereby amplifying the degree of stroke amplification and facilitating the storage of the traction belt 8 after reeling.

[0091] The user pushes the hand-held portion 711 to move toward the direction approaching the first positioning member 18, and the connecting support portion 719 moves synchronously and reels the traction belt 8 through the connecting rod type stroke amplification mechanism. When the reeling operation of the traction belt 8 is completed, the first positioning member 18 and the second positioning member 34 are attracted to each other, thereby realizing the positioning of the traction belt 8 after reeling. When the traction belt 8 needs to be unwound, the user pushes the hand-held portion 711 to move away from the first positioning member 18, and the first positioning member 18 and the second positioning member 34 are moved away from each other to release the positioning, thereby realizing the rapid unwinding of the traction belt 8. The reeling and unwinding operations of the traction belt 8 are performed by pushing the hand-held portion 711 on the top of the cover body 2, and the operation is simple and convenient.

[0092] Example 9

[0093] For ease of understanding, in this embodiment, the moving direction of the active member 611 is defined as a first direction, and the moving direction of the driven member 621 is defined as a second direction, and the cup cover is described based on this.

[0094] Reference Fig.10 and Fig.11 The cup cover includes a cup cover base 1, a traction belt 8 and a stroke amplification structure. A fixing rod 03 is fixedly provided on the upper surface of the cup cover base 1. A ring-shaped member 82 is fixedly provided at one end of the traction belt 8. The ring-shaped member 82 is sleeved on the fixing rod 03, so as to realize the fixed connection between one end of the traction belt 8 and the cup cover base 1. A through hole 14 is also provided on the upper surface of the cup cover base 1. The through hole 14 and the fixing rod 03 are respectively located on two opposite sides of the cup cover base 1. The other end of the traction belt 8 passes through the through hole 14 and is used to connect with the tea brewing part 91, and the diameter of the traction belt 8 is smaller than the diameter of the through hole 14. In this embodiment, the tea brewing part 91 is used to hold tea leaves, and the specific tea brewing part 91 can be a tea warehouse or a tea bag.

[0095] Reference Fig.10 and Fig.11 The stroke amplification structure is a combined structure formed by a gear structure 4 and a connecting rod structure 5. The gear structure 4 and the connecting rod structure 5 are linked to each other, and the traction belt 8 passes through the connecting rod structure 5; the cup cover also includes a driving mechanism 7, which is used to drive the gear structure 4 to operate and thereby drive the connecting rod structure 5 to operate. The connecting rod structure 5 causes the traction belt 8 to bend during operation. When the traction belt 8 bends, the tea brewing component 91 moves toward the direction close to the cup cover base 1, and the output stroke of the traction belt 8 is greater than the input stroke of the driving mechanism 7.

[0096] Reference Fig.10 and Fig.11 The gear structure 4 includes a linkage gear 63 and a linkage rack 64. The linkage gear 63 is rotatably connected to the cup cover base 1, and the linkage rack 64 is slidably matched with the cup cover base 1. The linkage gear 63 and the linkage rack 64 are meshed with each other. The linkage rack 64 drives the connecting rod structure 5 to operate when sliding. The linkage gear 63 is driven to rotate by the driving mechanism 7. The linkage gear 63 drives the linkage rack 64 to slide when rotating. The linkage rack 64 drives the connecting rod structure 5 to operate when sliding, thereby driving the tea brewing component 91 to move toward or away from the cup cover base 1.

[0097] Reference Fig.10 and Fig.11 Specifically, a carrier platform 04 is fixedly provided on the upper surface of the cup cover base 1, and a first rotating shaft 05 is fixedly provided on the upper surface of the carrier platform 04, and the first rotating shaft 05 extends in the vertical direction. The linkage gear 63 is sleeved on the first rotating shaft 05, and the linkage gear 63 is rotationally connected with the first rotating shaft 05, and the lower surface of the linkage gear 63 abuts against the top of the carrier platform 04, and the carrier platform 04 has an upward supporting effect on the linkage gear 63. The linkage rack 64 is slidably matched with the cup cover base 1; the linkage gear 63 and the linkage rack 64 are meshed with each other, and the linkage rack 64 drives the connecting rod structure 5 to operate when sliding.

[0098] When the tea is brewed, the driving mechanism 7 is used to drive the gear structure 4 to operate, thereby driving the connecting rod structure 5 to operate, so that the traction belt 8 is bent multiple times. When bending, the traction belt 8 drives the tea brewing piece 91 to move towards the direction close to the cup cover base 1; when tea needs to be brewed, since the movement stroke of the driving mechanism 7 is smaller than the movement stroke of the traction belt 8, the driving mechanism 7 causes the traction belt 8 to unwind quickly, and then the tea brewing piece 91 connected to the traction belt 8 falls quickly, thereby achieving fast tea brewing.

[0099] Reference Fig.10 and Fig.11 The connecting rod structure 5 includes a linkage assembly 61 and a stroke amplification assembly 62. The linkage rack 64 drives the linkage assembly 61 to operate during the sliding process. The linkage assembly 61 is used to drive the stroke amplification assembly 62 to operate. The stroke amplification assembly 62 causes the traction belt 8 to bend during the operation. The linkage gear 63 is driven to rotate by the driving mechanism 7. The linkage gear 63 drives the linkage rack 64 to slide. When the linkage rack 64 slides, the linkage assembly 61 is driven to operate. When the linkage assembly 61 operates, the stroke amplification assembly 62 is driven to operate. When the stroke amplification assembly 62 operates, the traction belt 82 is bent, so that the tea brewing component 91 rises, thereby achieving tea and water separation.

[0100] Reference Fig.10 and Fig.11 In this embodiment, each stroke amplification component 62 includes two followers 621, and the two followers 621 are both slidably matched with the cup cover base 1, and the sliding direction of the followers 621 is the second direction. The traction belt 8 passes through the followers 621, and the traction belt 8 and the followers 621 are slidably matched. Specifically, a through hole 6213 or a ring or a hook can be provided at one end of the two followers 621 close to each other, and the traction belt 8 passes through the through hole 6213 or the ring or the hook. The linkage component 61 is used to drive the stroke amplification component 62 to operate, so that the two followers 621 in the stroke amplification component 62 move toward or away from each other. When the linkage component 61 drives the stroke amplification component 62 to operate, when the two followers 621 in the stroke amplification component 62 move in directions away from each other, the two followers 621 drive the traction belt 8 to bend. Since the total length of the traction belt 8 remains unchanged, the traction belt 8 drives the tea brewing component 91 to rise during the bending process, thereby realizing the separation of tea and water; when it is necessary to brew tea again, the linkage component 61 drives the stroke amplification component 62 to operate, so that the two followers 621 in the stroke amplification component 62 move in a direction close to each other, thereby reducing the bending amount of the traction belt 8, and the tea brewing component 91 descends under the action of its own gravity, thereby realizing re-brewing of tea.

[0101] Reference Fig.10 and Fig.11The linkage assembly 61 includes an active member 611 and two linkage members 612. The active member 611 is slidably matched with the cup cover base 1. The driving mechanism 7 is used to drive the active member 611 to slide along the first direction. The motion trajectory of the active member 611 and the motion trajectory of the driven member 621 have an intersection. One end of the linkage member 612 is rotatably connected to the active member 611, and the other end of the linkage member 612 is rotatably connected to the driven member 621. Since the motion trajectory of the active member 611 and the motion trajectory of the driven member 621 have an intersection. One end of the linkage member 612 is rotatably connected to the active member 611, and the other end of the linkage member 612 is rotatably connected to the driven member 621. Therefore, when the driving mechanism 7 drives the active member 611 to slide, the active member 611 simultaneously drives one end of the two linkage members 612 to move along the motion trajectory of the active member 611, and the other ends of the two linkage members 612 respectively drive the two driven members 621 to move in the direction of approaching or moving away from each other, thereby changing the bending amount of the traction belt 8.

[0102] In this embodiment, the movement trajectory of the active member 611 and the movement trajectory of the driven member 621 can also be perpendicular to each other. When the movement trajectory of the active member 611 and the movement trajectory of the driven member 621 are perpendicular to each other, the active member 611 can drive the two driven members 621 to move a greater distance during the movement. Therefore, when the length of the traction belt 8 remains unchanged, the movement stroke of the driving mechanism 7 is further reduced.

[0103] A plurality of support seats 01 are fixedly arranged on the cup cover base 1, and the plurality of support seats 01 are rectangular. The active member 611 abuts against the support seat 01, and the active member 611 slides with the support seat 01. The support seat 01 not only supports the active member 611, but also guides the active member 611, thereby increasing the stability of the movement of the active member 611.

[0104] Reference Fig.10 and Fig.11Specifically, the linkage member 612 includes a connecting rod 6121, a first sleeve tube 6122 and a second sleeve tube 6123. One end of the connecting rod 6121 is fixedly connected to the first sleeve tube 6122, and the other end of the connecting rod 6121 is fixedly connected to the second sleeve tube 6123; the first sleeve tube 6122 is rotationally connected to the active member 611, and the second sleeve tube 6123 is rotationally connected to the driven member 621. The length direction of the connecting rod 6121 intersects with the motion trajectory of the first sleeve tube 6122. Since the length direction of the connecting rod 6121 intersects with the movement trajectory of the first sleeve tube 6122, the active member 611 drives the first sleeve tube 6122 to move during the movement, and at the same time makes the sleeve and the active member 611 rotate relative to each other. The sleeve drives the connecting rod 6121 to move during the movement, and the connecting rod 6121 drives the second sleeve tube 6123 to move. Since the second sleeve tube 6123 is rotationally connected to the driven member 621, the second sleeve tube 6123 drives the driven member 621 to move during the movement.

[0105] The active member 611 includes an active block 6111, which is slidably matched with the cup cover base 1, and a linkage rack 64 is integrally formed on a side of the active block 6111 close to the linkage gear 63. An active rod 6112 is provided on the active block 6111, and a first sleeve 6122 is sleeved on the active rod 6112 and is rotatably connected to the active rod 6112. When the active member 611 moves, the active rod 6112 moves, and when the active rod 6112 moves, the first sleeve 6122 rotates around the active rod 6112, and when the first sleeve 6122 rotates, the connecting rod 6121 moves, and the other end of the connecting rod 6121 drives the driven member 621 to move.

[0106] Reference Fig.10 and Fig.11 The follower 621 includes a follower block 6211 and a follower rod 6212, and the follower block 6211 is slidably matched with the cup cover base 1. The follower rod 6212 is fixed on the follower block 6211, and the second sleeve tube 6123 is sleeved on the follower rod 6212 and is rotatably connected to the follower rod 6212. When the connecting rod 6121 moves, it drives the second sleeve tube 6123 to move. Since the second sleeve tube 6123 is sleeved on the follower rod 6212 and is rotatably connected to the follower rod 6212, when the second sleeve tube 6123 moves, it drives the follower rod 6212 to move. When the follower rod 6212 moves, it drives the follower block 6211 and the cup cover base 1 to slide relative to each other.

[0107] Reference Fig.10 and Fig.11In this embodiment, the number of the stroke amplification components 62 can be one or more groups. When the number of the stroke amplification components 62 is multiple groups, the multiple groups of stroke amplification components 62 are arranged at intervals on the active member 611 of the linkage component 61, and the traction belt 8 passes through the driven members 621 of the multiple groups of stroke amplification components 62 in sequence. Since the number of the stroke amplification components 62 is multiple groups, the multiple groups of stroke amplification components 62 are arranged at intervals on the active member 611, and the traction belt 8 passes through the driven members 621 of the multiple groups of stroke amplification components 62 in sequence, the traction belt 8 can be bent and deformed multiple times by the driving mechanism 7 running through the multiple groups of stroke amplification components 62 at the same time, further reducing the movement stroke of the driving mechanism 7.

[0108] A plurality of guide mechanisms 02 are provided on the cup cover base 1, and the number of the guide mechanisms 02 is the same as the number of the driven blocks 6211, and the driven blocks 6211 slide and cooperate with the guide mechanisms 02. The guide mechanism 02 has a guiding effect on the driven blocks 6211, thereby increasing the stability of the sliding of the driven blocks 6211. In this embodiment, each guide mechanism 02 includes two guide blocks 021, and the two guide blocks 021 are fixed to the upper surface of the cup cover base 1, and each guide block 021 extends along the second direction, and a guide groove 022 is formed between the two guide blocks 021, and the driven member 621 slides and cooperates with the guide groove 022. Preferably, the sum of the thickness of the driven block 6211 and the diameter of the two traction belts 8 is less than the width of the guide groove 022, thereby improving the smoothness of the movement of the guide block 021 and the traction belt 8 in the guide groove 022 during the process of the guide block 021 pulling the traction belt 8 to bend.

[0109] Reference Fig.10 and Fig.11 In this embodiment, the specific driving mechanism 7 includes a rotating gripping member 724, which is fixedly connected to the linkage gear 63. A through rotating hole 201 is provided on the upper surface of the cover body 2, and the rotating gripping member 724 passes through the rotating hole 201. The rotating gripping member 724 is rotatably connected to the cover body 2, and the top of the rotating gripping member 724 protrudes from the cover body 2. The rotating gripping member 724 is rotated by applying an external force from the top of the cover body 2, thereby driving the connecting rod structure 5 to operate.

[0110] Reference Fig.10 and Fig.11The cup cover is provided with a positioning mechanism, which has a positioning function for the connecting rod structure 5. In this embodiment, the positioning mechanism includes a first positioning member 18 and a second positioning member 34. A first mounting cylinder 6113 is fixedly provided on the upper surface of the active member 611, and the second positioning member 34 is fixed in the first mounting cylinder 6113. A second mounting cylinder 206 is fixedly provided on the inner side wall of the cover body 2, and the first positioning member 18 is fixed in the second mounting cylinder 206. There is a magnetic attraction between the first positioning member 18 and the second positioning member 34, and the first positioning member 18 and the second positioning member 34 can be magnets. Because when the traction belt 8 drives the tea brewing component 91 to move to the position of the cup cover base 1 when it is bent and deformed, the second positioning component 34 on the active component 611 has a magnetic effect on the first positioning component 18 on the cover body 2. Therefore, when the tea is brewed, the second positioning component 34 has a magnetic effect on the first positioning component 18, so that the active component 611 is magnetically attracted to the cover body 2, so that the active component 611 will not move relative to the cover body 2, so that the traction belt 8 always maintains the maximum deformation, thereby realizing the separation of tea and water.

[0111] The implementation principle of Example 9 is as follows: after the tea is brewed, the rotating grip 724 is rotated by applying an external force from the top of the cover body 2, and the rotating grip 724 drives the linkage gear 63 to rotate. The linkage gear 63 drives the linkage rack 64 to slide when rotating, and the linkage rack 64 drives the active member 611 to slide along the length direction of the support seat 01 when sliding. The active member 611 drives the connecting rod structure 5 to operate when sliding, and the connecting rod structure 5 causes the traction belt 8 to bend multiple times when running, thereby driving the tea brewing part 91 to rise, thereby realizing the separation of tea and water; when it is necessary to brew tea again, the rotating grip 724 is rotated in the opposite direction, thereby driving the linkage gear 63 to rotate in the opposite direction, and the linkage gear 63 drives the linkage rack 64 to slide in the opposite direction, thereby reducing the bending amount of the traction belt 8, causing the tea brewing part 91 to fall, thereby realizing quick tea brewing.

[0112] Example 10

[0113] The difference between Example 10 and Example 1 is that, with reference to Fig.12 and Fig.13The stroke amplification mechanism includes a pull rope structure 6, a through hole 14 is provided on the cup cover base 1, a free end of the traction belt 8 passes through the through hole 14, and an end of the traction belt 8 away from the free end is connected to the cup cover base 1 or the stroke amplification mechanism.

Specifically, the driving mechanism 7 includes a driving rod 790, which is arranged on the side of the cover body 2 close to the cup cover base 1. The pull rope structure 6 includes a pull rope 66, which is provided with an active end and a driven end. The driven end of the pull rope 66 is connected to the traction belt 8, and the active end of the pull rope 66 is connected and cooperated with the driving rod 790. By applying external force to the cover body 2, the cover body 2 is caused to rotate along the cup cover base 1. During the rotation of the cover body 2, the driving rod 790 is driven to rotate. During the rotation, the driving rod 790 drives the active end of the pull rope 66 to rotate along the circumferential edge of the cup cover base 1, so that the traction belt 8 is folded in half to amplify the stroke of the traction belt 8, so as to drive the traction belt 8 to be quickly reeled or unreeled.

[0114] Reference Fig.12 and Fig.13 Specifically, there are multiple pull rope structures 6, and the driven end of the pull rope 66 of each pull rope structure 6 is movably connected to the traction belt 8. The other end of the traction belt 8 is connected to the cup cover base 1 or the pull rope structure 6. The driving mechanism 7 is simultaneously connected to the active ends of multiple pull ropes 66 to realize multiple stroke amplification and traction of the traction belt 8; the driven end of the pull rope 66 is provided with a first connecting piece 67, and the first connecting piece 67 is ring-shaped or hook-shaped.

The pull rope 66 drives the first connecting piece 67 to move during the movement, and the first connecting piece 67 drives the traction belt 8 to move during the movement, so as to facilitate the traction belt 8 to be reeled or unreeled.

[0115] Reference Fig.12 and Fig.13 The active end of the pull cord 66 is fixedly provided with a second connecting member 68, which is ring-shaped or hook-shaped, and the driving rod 790 passes through the second connecting member 68, and the second connecting member 68 is rotatably connected to the driving rod 790. Since the second connecting member 68 is rotatably connected to the driving rod 790, when the cover body 2 drives the driving rod 790 to rotate, the second connecting member 68 protects the active end of the pull cord 66, thereby extending the service life of the pull cord 66.

[0116] Further, in this embodiment, a plurality of guide structures 69 are provided on the cup cover base 1, each guide structure 69 includes a guide slot 691 and two guide strips 692, each pull rope 66 is correspondingly passed through the guide slot 691, the pull rope 66 can move in the guide slot 691, and the traction belt 8 can be pulled into the guide slot 691 by the pull rope 66 to realize winding or unwinding of the traction belt 8. The guide slot 691 defines the movement trajectory of the pull rope 66 and the traction belt 8.

[0117] Reference Fig.12 and Fig.13 Furthermore, the active end of the pull rope 66 extends out of one end of the guide slot 691. Under the action of the guide structure 69, the driving mechanism 7 drives the active end of the pull rope 66 to rotate along the circumferential edge of the cup cover base 1 to achieve traction of the traction belt 8, so that the traction belt 8 can be reeled in or unreeled.

[0118] Further, refer to Fig.12 and Fig.13 In this embodiment, the positioning mechanism includes a first positioning member 18 and a second positioning member 34.

In this embodiment, the first positioning member 18 and the second positioning member 34 are magnetically matched. When the traction belt 8 is wound up, the first positioning member 18 has a good fixing effect on the second positioning member 34 on the cover body 2.
