Description

Technical Field

[0001] The present application relates to the field of tea sets, and in particular to a gear-type stroke amplification mechanism for a cup cover, a cup cover and a water cup. Background Art

[0002] As people's health awareness gradually improves, various types of health-preserving infusions have gradually come into the consumers' field of vision. There are usually instant infusions and infusions that are not easily soluble in water. After the instant infusions are placed in a cup and liquid is added, the active ingredients quickly dissolve and diffuse into the liquid; while infusions that are not easily soluble in water usually need to be soaked in liquid so that their active ingredients can be slowly released into the liquid.

[0003] In order to solve the problem that the concentration of the insoluble brewing material is too high due to being soaked in the liquid for a long time, thus affecting the drinking taste of consumers, existing water cups on the market are usually provided with a traction rope on the cup lid that can realize the lifting and lowering of the tea brewing device (such as a tea chamber, tea bag and other structures for holding the insoluble brewing material). One end of the traction rope is passed through the cup lid, and the fixed end of the traction rope is connected to the tea brewing device. The consumer only needs to pull the traction rope to separate the tea brewing device from the liquid or re-immerse it in the liquid, thereby realizing the control of the concentration of the beverage.

[0004] However, in actual application, when consumers need to lift the tea-making device, they need to fully pull the traction rope connected to the tea-making device to separate the tea-making device from the liquid. If the distance between the tea-making device and the cup cover is longer, the pulling amplitude of the traction rope also needs to be increased, which requires consumers to separate the tea-making device from the liquid for a longer time, affecting the consumer's usage experience. Further improvement is needed. Utility Model Content

[0005] In order to solve the problem that the existing tea brewing cup with a traction mechanism cannot achieve the rapid separation of the tea compartment and the tea, thereby reducing the practicality of the tea brewing cup, the present application provides a gear-type stroke amplification mechanism for a cup cover, a cup cover and a cup.

[0006] In the first aspect, the present application provides a gear-type stroke amplification mechanism for a cup cover adopts the following technical solution:

[0007] A gear-type stroke amplification mechanism for a cup cover comprises a cup cover base, a through hole is formed on the cup cover base, a traction belt is arranged on the cup cover base, a stroke amplification component and a driving member are arranged on the cup cover base, the stroke amplification component comprises a gear structure, the driving member is used to drive the gear structure to move, the fixed end of the traction belt passes through the through hole and is connected to the gear structure, the free end of the traction belt can move away from or close to the cup cover base under the drive of the gear structure, the driving member drives the gear structure to move to drive the traction belt to perform stroke amplification movement, and the input stroke of the driving member to the gear structure is smaller than the output stroke of the traction belt.

[0008] By adopting the above technical solution, when the free end of the traction belt needs to move toward the cup lid base, the gear structure is driven by the driving member. At this time, the travel distance of the free end of the traction belt toward the cup lid base is greater than the action travel distance of the driving member, that is, the free end of the traction belt can be moved a longer distance toward the cup lid base by applying a smaller action to the driving member, thereby achieving rapid traction of the free end of the traction belt toward the cup lid base, which is highly practical.

[0009] Preferably, the gear structure includes an outer gear ring, an inner gear ring and a first transmission gear, the outer gear ring and the inner gear ring are respectively rotatably carried on the cup cover base, the first transmission gear is rotatably carried on the cup cover base, and the first transmission gear is located between the outer gear ring and the inner gear ring, and meshes with the outer gear ring and the inner gear ring, the driving member is used to drive the outer gear ring or the inner gear ring to rotate, the outer gear ring and the inner gear ring rotate in opposite directions, a connecting member is provided on the outer gear ring, the fixed end of the traction belt is connected to the connecting member, and a first guide winding member is provided on the inner gear ring, the first guide winding member is located between the penetration hole and the fixed end of the traction belt, and can drive any point on the traction belt to move away from the fixed end.

[0010] By adopting the above technical scheme, the outer gear ring and the inner gear ring are respectively meshed with the transmission gear. When the driving member drives the outer gear ring or the inner gear ring to rotate, the outer gear ring and the inner gear ring rotate in opposite directions along the first transmission gear respectively. Because the fixed end of the traction belt is connected to the connecting member, and the inner gear ring is provided with a first guide winding member, the connecting member carries the fixed end of the traction belt and rotates synchronously with the outer gear ring. At the same time, the first guide winding member drives any point between the through hole and the fixed end of the traction belt to rotate with the inner gear ring, that is: when the driving member drives the outer gear ring or the inner gear ring to rotate, the first guide winding member drives the traction belt to rotate in the opposite direction to the fixed end of the traction belt, and the traction belt is simultaneously wound twice in different directions in the cup cover base. At this time, the distance moved from the free end of the traction belt to the cup cover base is greater than the stroke driven by the driving member to drive the outer gear ring or the inner gear ring to rotate.

[0011] Preferably, a second toothed ring and a second transmission gear are provided on the cup cover base, the second toothed ring and the second transmission gear are rotatably carried on the cup cover base, and the second transmission gear is located between the second toothed ring and the inner toothed ring, and meshes with the second toothed ring and the inner toothed ring, a second guide winding member is provided on the second toothed ring, the second guide winding member is located between the penetration hole and the first guide winding member, and can drive any point of the traction belt between the penetration hole and the first guide winding member to move away from the first guide winding member.

[0012] By adopting the above technical solution, when any one of the outer gear ring, the inner gear ring or the second gear ring rotates, the outer gear ring and the second gear ring rotate in the same direction, but the inner gear ring and the outer gear ring and the second gear ring rotate in opposite directions. Through the guiding effect of the second guide winding member, each rotation of the outer gear ring, the inner gear ring or the second gear ring can wrap the traction belt three times along the cup lid base, so that the fixed end of the traction belt can be pulled to the cup lid base more quickly.

[0013] Preferably, a plurality of the first transmission gears and the second transmission gears are provided, and a plurality of the first transmission gears are located between the outer gear ring and the inner gear ring, and any one of the first transmission gears is meshed with the outer gear ring and the inner gear ring; a plurality of the second transmission gears are located between the inner gear ring and the second gear ring, and any one of the first transmission gears is meshed with the inner gear ring and the second gear ring, and any one of the second transmission gears is meshed with the inner gear ring and the second gear ring.

[0014] By adopting the above technical solution, several first transmission gears are meshed with the outer gear ring and the inner gear ring, and several second transmission gears are meshed with the inner gear ring and the second gear ring. When the outer gear ring, the inner gear ring or the second gear ring rotates, the outer gear ring and the inner gear ring can stably rotate along the several first transmission gears, thereby making the second gear ring stably rotate along the several second transmission gears, thereby improving the stability of the outer gear ring, the inner gear ring and the second gear ring when rotating, and also reducing the probability of gear slippage caused by excessive resistance encountered by the first transmission gear and / or the second transmission gear when the outer gear ring, the inner gear ring or the second gear ring rotates.

[0015] Preferably, the outer gear ring is covered on the inner gear ring, the outer gear ring and the inner gear ring are both meshed with the first transmission gear, and the outer gear ring is rotatably connected to the cup cover base.

[0016] By adopting the above technical solution, the inner gear ring is arranged inside the outer gear ring, which reduces the probability of foreign matter entering between the inner gear ring and the outer gear ring along the gap due to the gap between the outer gear ring and the inner gear ring, thereby causing jamming when the outer gear ring and the inner gear ring rotate.

[0017] Preferably, the outer toothed ring is provided with a hollow area matching the shape of the inner toothed ring along the geometric center toward the edge of the outer toothed ring, and when the driving member drives the outer toothed ring or the inner toothed ring to rotate, the inner toothed ring rotates along the hollow area.

[0018] By adopting the above technical solution, when the outer gear ring is rotated, the rotation state of the inner gear ring can be intuitively understood. At the same time, when the inner gear ring is rotated, the rotation state of the outer gear ring can also be intuitively understood, thereby enhancing the sensory experience of consumers.

[0019] Preferably, a winding radius limiting piece is provided on the cup cover base between the penetration hole and the connecting piece, and the fixed end of the traction belt is movably penetrated through the winding radius limiting piece and connected to the connecting piece.

[0020] By adopting the above technical solution, the winding radius of the fixed end of the connecting member carrying the traction belt along the cup lid base is limited by the winding radius limiting member, so that the fixed end of the traction belt is wound within the range limited by the winding radius limiting member. At the same time, the longer the distance from the winding radius limiting member to the geometric center of the cup lid base, the larger the radius of the fixed end of the connecting member carrying the traction belt along the cup lid base. Under the same rotation angle of the inner gear ring or the outer gear ring, the larger the winding radius of the fixed end of the connecting member carrying the traction belt along the cup lid base, the longer the rising distance from the free end of the traction belt to the cup lid base, thereby realizing rapid traction of the free end of the traction belt.

[0021] Preferably, an annular guide groove is provided on the cup cover base, and when the connecting member rotates following the outer gear ring, the connecting member carries the fixed end of the traction belt to move along the annular guide groove.

[0022] By adopting the above technical solution, when power is applied to the outer gear ring or the inner gear ring to rotate, the fixed end of the connecting member carrying the traction belt can be wound in an orderly manner along the annular guide groove, thereby reducing the probability of the traction belt being tangled in the cup lid base.

[0024] A cup cover comprises the above-mentioned gear-type stroke amplification mechanism for the cup cover.

[0025] By adopting the above technical solution, a cup cover is obtained in which a driving member can drive a gear structure to realize a travel distance of the traction belt greater than the action travel distance of the driving member, thereby realizing rapid traction of the free end of the traction belt to the cup cover base, which is highly practical.

[0026] Preferably, the driving member is disposed on the side or top of the cup cover, and the driving member can drive the gear structure to move by pushing, pressing or rotating, thereby making the free end of the traction belt approach or move away from the penetration hole.

[0027] By adopting the above technical solution, the driving member can be set on the side wall or top of the cup cover, and can drive the outer gear ring or the inner gear ring to rotate. The driving gear structure has various action modes and can be flexibly changed according to the actual shape or size of the cup cover, and has a wide range of applications.

[0029] By adopting the above technical solution, after the driving member and / or the stroke amplification component is running, the reset mechanism can reset the driving member or the stroke amplification component.

[0030] Preferably, the reset mechanism is a reset spring, one end of the reset spring abuts against the cup cover base, and the other end of the reset spring abuts against the driving member, when the stroke amplification component and / or the driving member rewinds the traction belt, the driving member squeezes the reset spring, and the reset spring stores elastic potential energy, and when the reset spring releases the elastic force, the driving member and / or the stroke amplification component returns to an initial position.

[0031] By adopting the above technical solution, since one end of the return spring abuts against the base of the cup lid and the other end of the return spring abuts against the driving member, the stroke amplification component or the driving member squeezes the return spring during operation, so that the return spring stores elastic potential energy. When the return spring releases the elastic force, the stroke amplification component and / or the driving member returns to the initial position, thereby enhancing the consumer's usage experience.

[0037] By adopting the above technical solution, the outer gear ring is driven to rotate by pressing the pressing piece to move along the guide piece.

When the pressing piece is pressed, the pressing piece pushes the guide rail to move from the higher end to the lower end, thereby reducing the resistance encountered when the pressing piece drives the outer gear ring to rotate. During this process, the free end of the traction belt begins to move toward the base of the cup cover, that is, the moving distance of the traction belt is greater than the moving distance of the pressing piece along the guide rail, thereby achieving rapid traction of the traction belt toward the base of the cup cover.

[0040] Preferably, the driving member is configured as an elastic member, the fixed end of the elastic member is connected to the cup cover base, and a transmission member is provided on the outer toothed ring.

[0043] By adopting the above technical solution, when the elastic part undergoes elastic deformation, the free end of the elastic part moves along the end of the guide block away from the outer gear ring to the end close to the outer gear ring. At this time, the moving distance of the traction belt is greater than the moving distance of the guide block along the elastic part. The operation is simple, and the elastic part can be automatically reset, which is highly practical.

[0044] Preferably, a positioning component for limiting the movement of the gear structure and / or the driving member is provided on the cup cover base.

[0094] Example 1

[0095] Reference Figure 2 and Figure 3The gear structure 4 includes an outer gear ring 41, an inner gear ring 42 and a first transmission gear 43. The outer gear ring 41 and the inner gear ring 42 are respectively rotatably supported on the cup cover base 1. The first transmission gear 43 is rotatably supported on the cup cover base 1. The first transmission gear 43 is located between the outer gear ring 41 and the inner gear ring 42 and meshes with the outer gear ring 41 and the inner gear ring 42. When the outer gear ring 41 or the inner gear ring 42 is driven to rotate by the driving member 5, the rotation directions of the outer gear ring 41 and the inner gear ring 42 are opposite. A connecting member 6 is provided on the outer gear ring 41 to connect Component 6 can be set as a component such as a penetration rod for fixing the fixed end of the traction belt 3. When the outer tooth ring 41 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 3. At the same time, a first guiding winding component 7 is set on the inner tooth ring 42. The first guiding winding component 7 is located between the penetration hole 2 and the fixed end of the traction belt 3. The first guiding winding component 7 can be set as a first guide rod or the like for guiding the traction belt 3 located between the penetration hole 2 and the penetration rod to be wound along the inside of the cup cover base 1.

[0096] Among them, one matching method of the outer gear ring 41 and the inner gear ring 42 is: Figure 4 The outer gear ring 41 is covered on the inner gear ring 42, and the outer gear ring 41 is rotatably connected to the cup cover base 1, which reduces the probability of jamming when the outer gear ring 41 and the inner gear ring 42 rotate due to the gap between the outer gear ring 41 and the inner gear ring 42, causing foreign matter to enter between the inner gear ring 42 and the outer gear ring 41 along the gap.

[0097] In addition, another matching method between the outer gear ring 41 and the inner gear ring 42 is: Figure 2 A hollow area 8 matching the shape of the inner gear ring 42 is provided at the edge of the outer gear ring 41 along the geometric center. When the driving member 5 drives the outer gear ring 41 or the inner gear ring 42 to rotate, the inner gear ring 42 rotates along the hollow area 8. Therefore, in this way, the rotation status of the outer gear ring 41 and the inner gear ring 42 can be intuitively understood, which plays a positive guiding role in improving the sensory experience value of consumers.

[0098] The implementation principle of Example 1 is: Figure 5 When the outer gear ring 41 or the inner gear ring 42 is driven to rotate by the driving member 5, the outer gear ring 41 and the inner gear ring 42 rotate in opposite directions along the first transmission gear 43 respectively, and the through-rod drives the fixed end of the traction belt 3 to rotate with the outer gear ring 41. At the same time, the first guide rod drives the traction belt 3 to rotate in the opposite direction to the fixed end of the traction belt 3. The traction belt 3 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 3 to the cup cover base 1 is greater than the stroke driven by the driving member 5 to drive the outer gear ring 41 or the inner gear ring 42 to rotate, so that the traction belt 3 can be quickly pulled to the cup cover base 1.

[0099] Example 2

[0100] The difference between Example 2 and Example 1 is that, referring to Figure 6 A second gear ring 9 and a second transmission gear 10 are provided on the cup cover base 1. The second gear ring 9 and the second transmission gear 10 are rotatably carried on the cup cover base 1, and the second transmission gear 10 is located between the second gear ring 9 and the inner gear ring 42, and is meshed with the second gear ring 9 and the inner gear ring 42. From the outside of the cup cover base 1 to the geometric center, there are respectively an outer gear ring 41, a first transmission gear 43, an inner gear ring 42, a second transmission gear 10 and a second gear ring 9. A second guide winding member 11 is provided on the second gear ring 9. The second guide winding member 11 can be set as a second guide rod or the like for guiding the traction belt 3 located between the penetration hole 2 and the first guide rod to be wound along the inside of the cup cover base 1.

[0101] The implementation principle of Example 2 is: when any one of the outer toothed ring 41, the inner toothed ring 42 or the second toothed ring 9 rotates, the outer toothed ring 41 and the second toothed ring 9 rotate in the same direction, but the inner toothed ring 42 rotates in the opposite direction to the outer toothed ring 41 and the second toothed ring 9. Through the guiding effect of the second guide rod, each rotation of the outer toothed ring 41, the inner toothed ring 42 or the second toothed ring 9 can wrap the traction belt 3 three times along the cup cover base 1. At this time, the distance that the free end of the traction belt 3 moves toward the cup cover base 1 is greater than the travel distance of the rotation of the outer toothed ring 41, the inner toothed ring 42 or the second toothed ring 9, and the free end of the traction belt 3 can be pulled to the cup cover base 1 more quickly.

[0102] At the same time, refer to Figure 4 and Figure 6 In Embodiment 1 and Embodiment 2, a plurality of first transmission gears 43 and a plurality of second transmission gears 10 may be provided, for example, three, four, five, etc. The plurality of first transmission gears 43 are arranged in a ring array between the outer gear ring 41 and the inner gear ring 42, and any first transmission gear 43 is meshed with the outer gear ring 41 and the inner gear ring 42; at the same time, the plurality of second transmission gears 10 are arranged in a ring array between the inner gear ring 42 and the second gear ring 9, and any first transmission gear 43 is meshed with the inner gear ring 42 and the second gear ring 9. The plurality of first transmission gears 43 and the plurality of second transmission gears 10 share the resistance encountered by the outer gear ring 41, the inner gear ring 42 and the second gear ring 9 during rotation, thereby reducing the probability of the first transmission gear 43 and / or the second transmission gear 10 encountering excessive resistance and causing gear slippage when the outer gear ring 41, the inner gear ring 42 or the second gear ring 9 rotates.

[0103] Example 3

[0104] The difference between Example 3 and Example 1 is that, referring to Figure 8A winding radius limiting member 12 is provided on the cup cover base 1 between the penetration hole 2 and the connecting member 6. The winding radius limiting member 12 here can be two limiting rods. The two limiting rods are provided between the penetration hole 2 and the connecting member 6, and on the cup cover base 1 near the connecting member 6, a gap is formed for the traction belt 3 to pass through. The fixed end of the traction belt 3 is movably penetrated through the winding radius limiting member 12 and connected to the connecting member 6.

[0105] The implementation principle of Example 3 is as follows: the winding radius of the fixed end of the traction belt 3 carried by the connecting member 6 along the cup lid base 1 is limited by the winding radius limiting member 12, so that the fixed end of the traction belt 3 is wound within the range limited by the winding radius limiting member 12. At the same time, the longer the distance from the winding radius limiting member 12 to the geometric center of the cup lid base 1, the larger the radius of the fixed end of the traction belt 3 carried by the connecting member 6 along the cup lid base 1. When the inner gear ring 42 or the outer gear ring 41 is at the same rotation angle, the larger the winding radius of the fixed end of the traction belt 3 carried by the connecting member 6 along the cup lid base 1, the longer the distance from the free end of the traction belt 3 to the rising of the cup lid base 1 is, thereby achieving rapid traction of the free end of the traction belt 3.

[0106] Example 4

[0107] The difference between Example 4 and Example 3 is that, referring to Fig. 9 The cup cover base 1 is provided with an annular guide groove 13 to form a groove for the traction belt 3 to be wound. In this embodiment, the distance from the annular guide groove 13 to the geometric center of the cup cover base 1 is the same as the distance from the connecting member 6 to the geometric center of the cup cover base 1. When the connecting member 6 rotates with the outer gear ring 41, the fixed end of the connecting member 6 carrying the traction belt 3 moves along the annular guide groove 13.

[0108] The implementation principle of Example 4 is: when the outer gear ring 41 or the inner gear ring 42 is driven to rotate by the driving member 5, the fixed end of the traction belt 3 carried by the connecting member 6 can be wound in an orderly manner along the annular guide groove 13, reducing the probability of the traction belt 3 being tangled in the cup lid base 1.

[0109] In a second aspect, an embodiment of the present application discloses a cup cover.

[0110] Reference Fig.10 A cup cover, based on the gear stroke amplification mechanism of Example 3, the driving member 5 can be set at any place of the cup cover base 1, the outer gear ring 41 or the inner gear ring 42, and can drive the outer gear ring 41 or the inner gear ring 42 to rotate, and the driving member 5 can drive the gear structure 4 to move by pushing, pressing or rotating, so as to make the free end of the traction belt approach or move away from the penetration hole 2. The driving gear structure 4 has various ways of moving and can be flexibly changed according to the actual shape or size of the cup cover.

[0111] Example 5

[0112] Reference Fig.10 The driving member 5 is configured as a rotating member 51 , and the rotating member 51 is disposed on the inner gear ring 42 or the outer gear ring 41 . The rotating member 51 is used to drive the inner gear ring 42 or the outer gear ring 41 to rotate along the cup cover base 1 .

[0113] The implementation principle of Example 5 is that the consumer can rotate the rotating member 51 to rotate the outer gear ring 41 or the inner gear ring 42, which is easy to operate.

[0114] Example 6

[0115] The difference between Example 6 and Example 5 is that, referring to Fig.10 (i) The driving member 5 is configured as an outer gear ring 41 body, and the outer gear ring 41 is rotatably connected to the cup cover base 1 .

[0116] The implementation principle of Example 6 is: the outer gear ring 41 body is set as the driving member 5, and the inner gear ring 42 can be rotated by simply rotating the outer gear ring 41, without adding an additional driving member 5, and the structure is simple.

[0117] Example 7

[0118] The difference between Example 7 and Example 6 is that, referring to Fig.11 The driving member 5 is configured as a pressing member 52, which is disposed on the cup cover base 1 and can slide along the axial direction of the cup cover base 1. A guide member 14 is disposed on the outer toothed ring 41, and the guide member 14 is inclined downward from one end away from the cup cover base 1 to the end close to the cup cover base 1. When the pressing member 52 moves downward along the thickness direction of the cup cover base 1, the pressing member 52 drives the outer toothed ring 41 to rotate along the guide member 14, and the moving stroke distance of the traction belt 3 is greater than the stroke distance of the pressing member 52 along the guide member 14. The outer toothed ring 41 is driven to rotate by pressing the pressing member 52 to move along the guide member 14. At this time, the moving stroke distance of the traction belt 3 is greater than the stroke distance of the pressing member 52 along the guide member 14, thereby realizing rapid traction of the free end of the traction belt 3 and easy operation.

[0119] One implementation method is: Fig.11 The guide member 14 is configured as a guide rail 141, which is disposed on the side wall of the outer gear ring 41, and the guide rail 141 is inclined downward from one end away from the cup cover base 1 to the end close to the cup cover base 1. When the pressing member 52 is pressed, the pressing member 52 pushes the guide rail 141 to move from the higher end to the lower end, thereby reducing the resistance encountered by the pressing member 52 when driving the outer gear ring 41 to rotate. During this process, the free end of the traction belt 3 begins to move toward the cup cover base 1, that is, the moving stroke distance of the traction belt 3 is greater than the moving stroke distance of the pressing member 52 along the guide rail 141, thereby realizing rapid traction of the traction belt 3 toward the cup cover base 1.

[0120] Example 8

[0121] The difference between Example 8 and Example 7 is that, referring to Fig.12 The driving member 5 is configured as an elastic member 53. The elastic member 53 can be made of a material that is elastic and can recover after elastic deformation (such as elastic plastic, etc.). The fixed end of the elastic member 53 is connected to the cup cover base 1. A transmission member 15 is provided on the outer gear ring 41. When the elastic member 53 is elastically deformed, the free end of the elastic member 53 abuts against the transmission member 15, causing the transmission member 15 to rotate. At this time, the outer gear ring 41 rotates synchronously with the transmission member 15, and the moving stroke distance of the traction belt 3 is greater than the stroke distance of the transmission member 15 moving along the elastic member 53.

[0122] One implementation method is as follows: the transmission member 15 is configured as a guide block 151, the guide block 151 is configured on the side wall of the outer gear ring 41, and the guide block 151 is inclined from an end away from the outer gear ring 41 to an end close to the outer gear ring 41. When the elastic member 53 undergoes elastic deformation, the free end of the elastic member 53 moves along the end of the guide block 151 away from the outer gear ring 41 to the end close to the outer gear ring 41. At this time, the moving stroke distance of the traction belt 3 is greater than the moving stroke distance of the guide block 151 along the elastic member 53. The operation is simple, and the elastic member 53 can be automatically reset, which is highly practical.

[0123] Example 9

[0124] Reference Fig.19 A reset mechanism 21 is provided on the cup cover, and the reset mechanism is used to drive the gear structure 4 and / or the driving member 5 to reset. When the gear structure 4 or the driving member 5 is running, the reset mechanism 21 can reset the gear structure 4 or the driving member 5.

[0125] Reference Fig.19 In this embodiment, the reset mechanism 21 is a reset spring, one end of the reset spring abuts against the cup cover base 1, and the other end of the reset spring abuts against the driving member 5. When the stroke is gradually enlarged and / or the driving member 5 reels the traction belt 3, the driving member 5 squeezes the reset spring, and the reset spring stores elastic potential energy. When the reset spring releases the elastic force, the driving member 5 and / or the gear structure 4 returns to the initial position.

[0126] Reference Fig.11 and Fig.19, the difference from Example 7 is that, in a specific implementation method, a sliding member 22 is provided on the side wall of the cup cover base 1 along the axial direction, and a pressing member 52 is slidably sleeved on the sliding member 22, and a mounting groove 23 is opened on the sliding member 22 along the length direction, and a reset spring is placed in the mounting groove 23. When the pressing member 52 is installed on the sliding member 22, one end of the reset spring abuts against the bottom of the mounting groove 23, and the other end of the reset spring abuts against the pressing member 52. When the consumer presses the pressing member 52, the outer tooth ring 41 rotates along the cup cover base 1 to achieve the winding of the traction belt 3. At this time, the reset spring stores elastic potential energy. When the consumer releases the pressing member 52, the pressing member 52 is affected by the elastic force of the reset spring and will be reset along the sliding member 22, so that the outer tooth ring 41 is reset along the cup cover base 1, and the purpose of unwinding the traction belt 3 is achieved.

[0127] Please refer to Fig.13 , a positioning assembly 16 for limiting the movement of the gear structure 4 and / or the driving member 5 is provided on the cup cover base 1. In this embodiment, the movement of the inner gear ring 42 and the outer gear ring 41 is limited by the positioning assembly 16. The positioning assembly 16 can be in the form of snap connection, sleeve connection, locking or magnetic attraction to limit the rotation of the gear structure 4 and / or the driving member 5 without external force intervention. When the inner gear ring 42 and the outer gear ring 41 move to a certain extent in opposite directions, that is, when the free end of the traction belt 3 approaches the cup cover base 1 to a certain extent, the positioning assembly 16 limits the inner gear ring 42 and the outer gear ring 41 to continue to rotate or reverse rotation, so that the traction belt 3 is contracted to a specific length and cannot continue to move away from or close to the cup cover base 1.

[0128] In one embodiment, the positioning assembly 16 includes a buckle and a slot. The buckle is arranged on the outer gear ring, and the slot is arranged on the cover body. When the free end of the traction belt 3 reaches the through hole 2, the buckle can be engaged with the slot, thereby limiting the outer gear ring 41 or the inner gear ring 42 from continuing to rotate, thereby achieving the positioning purpose.

[0129] Correspondingly, in another embodiment, the positioning assembly 16 includes a collar and a positioning rod, the collar is arranged on the outer gear ring, and the positioning rod is arranged on the cover body. When the free end of the traction belt 3 reaches the penetration hole 2, the collar can be used to sleeve the positioning rod, thereby limiting the outer gear ring 41 or the inner gear ring 42 from continuing to rotate, thereby achieving the positioning purpose.

[0130] Example 10

[0131] Reference Fig.13In the preferred implementation of this embodiment, the positioning assembly 16 includes a first positioning member 161 and a second positioning member 162. The first positioning member 161 is arranged on the cup cover base 1, and the second positioning member 162 is arranged on the outer gear ring 41. The first positioning member 161 and the second positioning member 162 are magnetically matched. There are three ways for the magnetic matching of the first positioning member 161 and the second positioning member 162:

[0132] a. The first positioning member 161 is magnetic, and the second positioning member 162 is non-magnetic but can be attracted by the first positioning member 161;

[0133] b. The second positioning member 162 is magnetic, and the first positioning member 161 is non-magnetic but can be attracted by the second positioning member 162;

[0134] c. Both the first positioning member 161 and the second positioning member 162 are magnetic, and the first positioning member 161 and the second positioning member 162 have opposite magnetic poles that attract each other.

[0135] The implementation principle of Example 10 is: when the free end of the traction belt 3 is close to the cup lid base 1, the first positioning member 161 and the second positioning member 162 can cooperate with each other magnetically, thereby limiting the inner gear ring 42 or the outer gear ring 41 from continuing to rotate, or, the magnetic cooperation within the first positioning member 161 and the second positioning member 162, through the way of snap-fitting and sleeve-fitting, makes it impossible for the free end of the traction belt 3 to move away from the cup lid base 1 when it reaches the cup lid base 1.

[0136] Embodiment 11

[0137] The difference between Example 11 and Example 10 is that, referring to Fig.14 , there are a plurality of first positioning members 161, for example, two, three, four, etc., and the plurality of first positioning members 161 are arranged on the cup cover base 1 in a circular array, and the second positioning member 162 can be magnetically matched with any first positioning member 161;

[0138] Or, refer to Fig.15 There are a number of second positioning members 162, such as two, three, four, etc. In the present embodiment, there are six second positioning members 162, which are arranged in a circular array on the outer gear ring 41, and the first positioning member 161 can be magnetically matched with any second positioning member 162.

[0139] The implementation principle of Example 11 is: the second positioning member 162 can be used to magnetically cooperate with a plurality of first positioning members 161 to achieve positioning of different distances during the movement of the free end of the traction belt 3 to the cup lid base 1, so that the free end of the traction belt 3 can be suspended at different heights, which is highly practical; similarly, the above-mentioned function can also be achieved through the magnetic cooperation of the first positioning member 161 and a plurality of second positioning members 162, and it can be changed according to actual production needs to make it easy to adjust the distance between the free end of the traction belt 3 and the cup lid base 1.

[0140] Example 12

[0141] The difference between Example 12 and Example 10 is that, referring to Fig.16 The second positioning member 162 is set as the main body of the first guide winding member 7, and the first positioning member 161 is set on the cup cover base 1. In this embodiment, the distance from the first positioning member 161 to the geometric center of the cup cover base 1 is the same as the distance from the first guide winding member 7 to the geometric center of the cup cover base 1, and the first positioning member 161 is magnetically matched with the first guide winding member 7.

[0142] The implementation principle of Example 12 is: the second positioning member 162 is set as the main body of the first guide winding member 7, and there is no need to add additional positioning members of other structures, which plays a positive guiding role in improving the space utilization of the cup cover. At the same time, the first positioning members 161 can also be provided with a plurality of them, such as two, three, four, etc., and the plurality of first positioning members 161 are arranged in a circular array on the cup cover base 1 along the radius of rotation of the first guide winding member 7, so as to realize the positioning of different distances from the free end of the traction belt 3 to the cup cover base 1 during the movement.

[0143] In a third aspect, Example 13 of the present application discloses a water cup.

[0144] A water cup, based on embodiment 12, further includes a cup body 20, and a cup cover is covered on the cup body 20, and the free end of the traction belt 3 can be connected to a tea brewing component 17, and the tea brewing component 17 can be a tea bin, tea bag, etc. for holding or containing brewed beverages.

[0145] Embodiment 14

[0146] The difference between Example 14 and Example 13 is that, referring to Fig.18 A connecting block 19 is provided at the free end of the traction belt 3, and the tea brewing component 17 and the connecting block 19 are matched by snap connection, sleeve connection or magnetic attraction; wherein the method of connecting the tea brewing component 17 and the connecting block 19 by snap connection and sleeve connection is an existing structure, and its specific method will not be repeated here.

[0147] When the tea brewing member 17 and the connecting block 19 are magnetically matched, it can be:

[0148] The connecting block 19 is magnetic, and the tea brewing component 17 is not magnetic, but the connecting block 19 can cooperate with the tea brewing component 17 by magnetic attraction;

[0149] Or, the connection block 19 is not magnetic, and the tea brewing component 17 is magnetic, but the connection block 19 can be magnetically matched with the tea brewing component 17;

[0150] Or, both the connecting block 19 and the tea brewing component 17 are magnetic, and the connecting block 19 and the tea brewing component 17 have opposite magnetic poles that attract each other.

[0151] The implementation principle of Example 14 is as follows: the tea brewing piece 17 can be magnetically matched with the tea brewing piece 19, so that the tea brewing piece 17 can be separated from the traction belt 3, which is convenient for cleaning the tea brewing piece 17 and has high practicality.

[0152] Embodiment 15

[0153] The difference between Example 15 and Example 14 is that a traction channel 18 is provided on the cup cover base 1, the free end of the traction belt 3 is movably penetrated in the traction channel 18 along the penetration hole 2, and the tea brewing component 17 is slidably disposed outside the traction channel 18.

[0154] The implementation principle of the embodiment 15 is as follows: the tea brewing member 17 can stably rise and fall along the traction channel 18, thereby improving the moving stability of the tea brewing member 17, and the traction channel 18 plays a good role in fixing the position of the tea brewing member 17 and the traction belt 3. At the same time, the end of the traction channel 18 in the water cup is blocked, so that the traction channel 18 is in a sealed state, and water is not easy to leak from the cover along the traction channel 18, thereby improving the sealing performance.

[0155] The implementation principle of the gear-type stroke amplification mechanism, cup cover and water cup for a cup cover in the embodiment of the present application is as follows: by providing a cup cover with a stroke amplification component, the water cup formed thereby can quickly pull the utensil for brewing beverages to the cup cover base 1, and has good convenience and practicality in use.

[0156] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
