Technical Field

[0001] This invention relates to the field of drinking water products technology, specifically to a water cup. Background Technology

[0002] Existing smart water bottles lack internal design features that isolate water vapor from electronic components such as motors and the inside of the bottle. Water vapor inside the bottle can enter the inside of the cap, directly damaging the motor and other electronic components and affecting their lifespan. At the same time, water vapor can accumulate and leak back into the bottle through the holes, contaminating the water source and affecting the health of the drinker.

[0003] Therefore, how to provide a water cup that can prevent water vapor from damaging the motor and a series of electronic components, thereby improving the safety of use, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

When the power mechanism is activated, the power mechanism controls the transmission mechanism to drive the locking mechanism to disengage from the slot of the cup body, and the cup lid assembly disengages from the cup body, thereby allowing the cup lid assembly to be removed and the water cup to be opened.

[0006] In some embodiments, the cup lid assembly includes a lid body, an upper cup lid, and a lower cup lid; the lid body is sealed to the upper cup lid to form a sealed first receiving cavity; the lower cup lid is partially connected to the upper cup lid to form a second receiving cavity; The upper cup cover includes a bottom wall that separates the first receiving cavity from the second receiving cavity, and a sealing ring; the bottom wall is provided with a shaft hole for the transmission mechanism to pass through, and the sealing ring of the upper cup cover is used to cooperate with the transmission mechanism and the shaft hole for sealing.

[0007] In some embodiments, the lower cup lid further includes a vent hole, a vent plug at least partially located within the vent hole, and a vent spring for controlling the movement of the vent plug; when the power mechanism is activated, the locking mechanism controls the vent plug to move downward, the vent hole is opened, and the air passage of the cup body and the air passage of the second receiving cavity are connected to the atmosphere; when the power mechanism is not working, the vent spring controls the vent plug to be inserted into the vent hole to close the vent hole.

[0009] In some embodiments, the first transmission assembly includes a first bevel gear disposed at the output end of the motor and a second bevel gear disposed at the first end of the transmission shaft, wherein the first bevel gear and the second bevel gear mesh with each other in the vertical direction, thereby changing the reversing transmission; The reference axis of the drive shaft is perpendicular to the reference axis of the motor output end; The second transmission assembly includes a spur gear sleeved on the second end of the transmission shaft, the spur gear being used to drive the locking mechanism to move; When the motor starts, the first bevel gear drives the transmission shaft to rotate through the second bevel gear, and the transmission shaft drives the locking mechanism to move through the spur gear.

[0010] In some embodiments, the side wall of the lower cup lid is provided with a through hole; The locking mechanism includes at least one locking block, a turntable with a rack, and a return spring connected to the locking block. The spur gear meshes with the rack of the turntable, and the turntable is rotatably connected to the lower cup lid. When the power mechanism is working, the power mechanism can control the turntable to rotate through the transmission mechanism, thereby driving the locking block to retract from the through hole, thereby causing the locking block to disengage from the slot; When the power mechanism is not working, the reset spring can control the locking block to extend out of the through hole and engage with the locking slot.

[0011] In some embodiments, the card block is provided with protrusions; The turntable includes a rotor; the rotor includes an inner arc-shaped strip and an outer arc-shaped strip connected to each other, the inner arc-shaped strip and the outer arc-shaped strip are connected to form a limiting hole, the radius of the inner arc-shaped strip is a fixed value, the radius of the outer arc-shaped strip gradually increases, the inner arc-shaped strip and the outer arc-shaped strip form a limiting hole with a gradually increasing width, the limiting hole includes a narrow end and a wide end, and the protrusion is located in the limiting hole and abuts against the outer arc-shaped strip; When the power mechanism is working, the turntable is driven to rotate by the power mechanism, the limiting hole rotates, the outer arc strip drives the protrusion to move towards the narrow end, thereby causing the locking block to retract and disengage from the locking groove, and at the same time the reset spring is compressed.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0021] Example 1 like Figures 1 to 7 As shown, this embodiment provides a water cup, including a cup body 1 for storing liquid, a cup lid assembly 2 installed on the opening of the cup body, a power mechanism 3, a locking mechanism 4, and a transmission mechanism 5.

[0022] In this embodiment, the cup lid assembly 2 includes a lid body 85, an upper cup lid 21, and a lower cup lid 22. The lid body 85 is sealed to the upper cup lid to form a first receiving cavity 211, and the upper cup lid 21 and the lower cup lid 22 are at least partially connected, forming a second receiving cavity 221 between them. The first receiving cavity 211 and the second receiving cavity 221 are arranged sequentially from top to bottom.

[0023] like Figure 6 As shown, the power mechanism 3 is located in the first receiving cavity 211; the locking mechanism 4 is located in the second receiving cavity 221; the transmission mechanism 5 has its first end connected to the power mechanism 3 and its second end connected to the locking mechanism 4. When the cup lid assembly 2 is placed over the opening of the cup body 1, the cup lid assembly 2 is pressed into the cup body 1, and at least a portion of the locking mechanism 4 is embedded in the slot 11 of the cup body 1, so that the cup lid assembly 2 cannot be removed from the cup body 1. That is, the cup lid assembly 2 and the cup body 1 are engaged by the locking mechanism 4 and the slot 11, so that the cup lid assembly 2 cannot be separated from the cup body 1, the cup cannot be opened, and the user can only spin the cup lid assembly 2 without water. When the power mechanism 3 is activated, the power mechanism 3 controls the transmission mechanism 5 to drive the locking mechanism 4 to disengage from the cup body 1, that is, the cup lid assembly 2 can be disengaged from the cup body 1, so that the cup lid assembly 2 can be removed, that is, the cup lid assembly 2 can be separated from the cup body 1, and the cup can be opened.

[0024] In this embodiment, the cup lid assembly 2 is preferably welded together from an upper cup lid 21 and a lower cup lid 22. The opening of the lower cup lid 22 is connected to the bottom of the upper cup lid 21 to form a second receiving cavity 221. The upper cup lid 21 forms a first receiving cavity 211 with the lid body 85, thereby jointly forming the above two receiving cavities, one above the other. In different embodiments, there may be three or more receiving cavities, depending on the situation.

[0025] like Figure 4 and Figure 10 As shown, in this embodiment, the upper cup lid 21 includes a bottom wall 213 and a sealing ring 54. The bottom wall 213 divides the internal space of the upper cup lid 21 to form a first receiving cavity 211 and a second receiving cavity 221. A shaft hole 214 is provided on the bottom wall 213 for the transmission mechanism to pass through.

[0026] like Figure 4 and Figure 6As shown, when the drive shaft 52 of the transmission mechanism 5 passes through the shaft hole 214, the sealing ring 54 seals the drive shaft and the shaft hole 214, thereby isolating the first receiving cavity 211 and the second receiving cavity 221 from each other by moisture, forming a seal between the first receiving cavity 211 and the second receiving cavity 221. Specifically, the drive shaft 52 passes through the shaft hole 214, the sealing ring 54 is sleeved on the drive shaft and embedded in the shaft hole 214, and the sealing ring 54 forms an interference fit with the inner wall of the shaft hole and the outer wall of the drive shaft, that is, the sealing ring 54 tightly seals the fit between the drive shaft and the shaft hole 214. To further seal the fit between the drive shaft 52 and the shaft hole 214, this embodiment also provides an ultrasonic sealing sheet 93, which is connected to the bottom wall 213 by ultrasonic plastic welding.

[0027] Specifically, the first receiving cavity 211 and the power mechanism 3 are both located in the upper cup cover 21, and the second receiving cavity 221 and the locking mechanism 4 are both located in the lower cup cover 22. In this embodiment, the upper cup cover 21 and the lower cup cover 22 can be ultrasonically welded to form a stable connection, which is beneficial for the cup cover assembly 2 not to disintegrate when the whole is separated from the cup body 1.

[0028] In different embodiments, the upper cup lid 21 can be integrally formed; or it can be integrally formed with a removable partition added inside to separate the space.

[0029] like Figure 4 and Figure 6 As shown, this invention provides a first receiving cavity 211 and a second receiving cavity 221 in the cup lid assembly 2. The power mechanism 3 in the first receiving cavity 211 unlocks the locking mechanism 4 in the second receiving cavity 221 via a transmission mechanism 5. On one hand, the power mechanism 3 and the locking mechanism 4 are spatially separated; on the other hand, even when separated, the power mechanism 3 can still control the locking mechanism 4 via the transmission mechanism 5 to open the cup. This invention isolates the first receiving cavity 211 and the second receiving cavity 221 from each other by moisture, forming a seal between them. This prevents water vapor from seeping from the second receiving cavity 221 into the first receiving cavity 211 and damaging the power mechanism 3. It also helps preserve the power mechanism 3 and other electronic components, prevents water contamination, and is beneficial to the health of the drinker.

[0030] like Figure 4 and Figure 6 As shown, in this embodiment, the cup lid assembly 2 includes an upper cup lid 21 and a lower cup lid 22. The opening of the lower cup lid 22 is located at the bottom of the upper cup lid 21. The first receiving cavity 211 and the power mechanism 3 are both located in the upper cup lid 21. The second receiving cavity 221 and the locking mechanism 4 are both located in the lower cup lid 22. The middle part of the first end and the second end of the transmission mechanism 5 passes through the bottom of the upper cup lid 21. In this embodiment, the locking mechanism 4 is disposed within the second receiving cavity 221 to lock or separate the cup lid assembly 2 from the cup body 1. The transmission mechanism 5 has its first end connected to the power mechanism 3 and its second end connected to the locking mechanism 4. The middle portion of the transmission mechanism 5 passes through the bottom wall of the upper cup lid 21, transmitting power from the power mechanism 3 to the locking mechanism 4.

[0031] like Figure 11 and Figure 12 As shown, the side wall of the lower cup lid 22 is provided with a through hole for at least a part of the locking mechanism 4 to extend out, and the inner wall of the cup body 1 is provided with a slot 11 corresponding to the through hole for engaging at least a part of the locking mechanism 4 extending out from the through hole.

[0032] In this embodiment, the slot 11 is an annular slot, and the through hole includes a first through hole 222 and a second through hole 223, which correspond to the first protrusion 431 and the second protrusion 461, respectively, thereby clamping the cup lid assembly 2 into the cup body.

[0033] like Figure 4 As shown, in this embodiment, the power mechanism 3 includes a motor 31 disposed in the first receiving cavity 211; the transmission mechanism 5 includes a first transmission component 51, a transmission shaft 52, and a second transmission component 53. The first end of the first transmission component 51 is connected to the output end of the motor 31, the second end of the first transmission component 51 is fixedly connected to the first end of the transmission shaft 52, the second end of the transmission shaft 52 is fixedly connected to the first end of the second transmission component 53, and the second end of the second transmission component 53 is connected to the locking mechanism 4.

[0034] like Figure 10 As shown, specifically, the first end of the first transmission assembly 51 is connected to the output end of the motor 31, and the second end is fixedly connected to the first end of the transmission shaft 52. The second end of the transmission shaft 52 is fixedly connected to the first end of the second transmission assembly 53, and the second end of the second transmission assembly 53 is connected to the locking mechanism 4.

[0035] like Figures 10 to 14As shown, in this embodiment, the first transmission component 51 includes a first bevel gear 511 disposed at the output end of the motor 31 and a second bevel gear 512 disposed at the first end of the transmission shaft 52. The first bevel gear 511 and the second bevel gear 512 mesh with each other in the vertical direction, thereby changing the reversing transmission. In this embodiment, it is a vertical reversing transmission. The reference axis of the transmission shaft 52 is perpendicular to the reference axis of the output end of the motor 31. The transmission shaft 52 passes through the bottom wall of the upper cup lid 21 from top to bottom. The second transmission component 53 is a spur gear 531 disposed at the second end of the transmission shaft 52. The spur gear 531 is used to drive the locking mechanism 4 to move. When the motor 31 starts, the first bevel gear 511 drives the transmission shaft 52 to rotate through the second bevel gear 512. The transmission shaft 52 drives the locking mechanism 4 to move through the spur gear 531.

[0036] In other embodiments, the first transmission component 51 may also be driven by two worm gears, or by one worm gear or one gear. The transmission shaft 52 may be a transmission shaft with threads at both ends. The transmission shaft 52 is adapted to the bottom of the upper cup lid and can rotate at its bottom.

[0037] like Figure 4 and Figure 7 As shown, in this embodiment, the drive shaft 52 is fitted with a sealing ring 54, which is embedded in the bottom of the upper cup cover 21; the bottom of the lower cup cover 22 is provided with a reset groove 224. like Figure 11 and Figure 12 As shown, the locking mechanism 4 includes a locking block, a turntable 44 with a rack 441, a turntable shaft 443, and a return spring 45 connected to the locking block. A spur gear 531 meshes with the rack 441 of the turntable 44. The turntable 44 is rotatably connected to the lower cup lid 22 via the turntable shaft 443. The return spring 45 is disposed in the return groove 224. The power mechanism 3 can control the turntable 44 to retract the locking block from the through hole via the transmission mechanism 5, thereby disengaging the locking block from the slot 11. The return spring 45 can control the locking block to extend out of the through hole and engage with the slot 11. One end of the return spring 45 is disposed in the return groove 224, and the other end is connected to the locking block.

[0038] In the initial state (locked state), under the elastic force of the return spring 45, the first locking block 43 and the second locking block 46 are pushed out of the first through hole 222 and the second through hole 223, and locked into the slot 11 of the cup body 1, thereby realizing the locking of the cup lid assembly 2 and the cup body 1, and the cup lid assembly 2 cannot be opened.

[0039] When unlocking is required, the user issues a command through the fingerprint module of the switch signal receiver 7, and the motherboard 32 controls the motor 31 to start. The motor 31 drives the second bevel gear 512 and the transmission shaft 52 to rotate through the first bevel gear 511. The spur gear 531 at the lower end of the transmission shaft 52 rotates accordingly, and drives the turntable 44 to rotate around the turntable shaft 443 through meshing with the rack 441. The turntable 44 is provided with a pair of rotors 442 arranged opposite each other. The first locking block 43 and the second locking block 46 are provided with a first protrusion 41 and a second protrusion 42 that abut against the rotors 442. When the turntable 44 rotates, the rotors 442 will press the first protrusion 41 and the second protrusion 42, overcome the elastic force of the return spring 45, and drive the first locking block 43 and the second locking block 46 to retract into the second receiving cavity 221, so that they are disengaged from the slot 11 of the cup body 1, and the unlocking is completed.

[0040] Optionally, the number of locking blocks can vary in different embodiments; there can be multiple locking blocks, such as three or four. That is, multiple locking blocks are arranged in a circular pattern, corresponding to multiple through holes, multiple rotors 442, and multiple limiting holes 446. Specifically, four rotors 442 arranged in a circular pattern in the turntable 44, with adjacent rotors 442 having an included angle of 90°, and each rotor 442 having four limiting holes 446, each limiting hole 446 drives one locking block. When the turntable 44 moves, the four rotors 442 drive the four locking blocks to retract from the locking groove 11 (annular groove), releasing the latch connection and unlocking the cup body 1.

[0041] like Figure 13 and Figure 14 As shown, in this embodiment, the rotor 442 includes an inner arc-shaped strip 4421 and an outer arc-shaped strip 4422 connected to each other. The radius of the inner arc-shaped strip 4421 is a constant value, while the radius of the outer arc-shaped strip 4422 gradually increases. A limiting hole 446 with gradually increasing width is formed between the inner arc-shaped strip 4421 and the outer arc-shaped strip 4422. The limiting hole 446 includes a narrow end 4461 and a wide end 4462. A protrusion is located inside the limiting hole 446 and abuts against the outer arc-shaped strip 4422.

[0042] Based on the above structural analysis, to ensure smooth movement and controllable force, the rotor 442 is designed to include an inner arc-shaped strip 4421 and an outer arc-shaped strip 4422 connected to each other. The radius of the inner arc-shaped strip 4421 is constant, while the radius of the outer arc-shaped strip 4422 gradually increases. This variable-diameter structure can smoothly drive the first protrusion 41 and the second protrusion 42 to extend and retract relative to the through hole. Specifically, when the power mechanism 3 is working, the turntable 44 is driven to rotate, the limiting hole 446 rotates, and the outer arc-shaped strip 4422 drives the protrusion to move towards the narrow end. As the inner diameter of the outer arc-shaped strip 4422 decreases (the width of the limiting hole 446 decreases), the locking block retracts and disengages from the locking groove 11, while the return spring 45 is compressed.

[0043] When the power mechanism 3 is not working, the reset spring 45 resets, generating elastic force to control the card block to extend out of the through hole and engage with the card slot 11.

[0044] like Figure 13 and Figure 14 As shown, in this embodiment, the locking block includes a first locking block 43 and a second locking block 46 symmetrically arranged; the reset spring 45 includes a first reset spring 451 and a second reset spring 452; the protrusion includes a first protrusion 41 and a second protrusion 42; and the through hole includes a first through hole 222 and a second through hole 223. The first locking block 43 also includes a first protruding member 431, a first connecting member 432, and a first fixing member 433. The first end of the first protruding member 431 protrudes from the first through hole 222; the first end of the first connecting member 432 is disposed on the bottom of the second end of the first protruding member 431; and the second end of the first connecting member 432 is connected to the first end of the first fixing member 433. The first protrusion 41 is disposed on the second end of the first protrusion 431, and the first return spring 451 is disposed on the second end of the first fixing member 433; the second locking block 46 also includes a second protrusion 461, a second connecting member 462 and a second fixing member 463. The first end of the second protrusion 461 extends out of the second through hole 223, the first end of the second connecting member 462 is disposed on the bottom of the second end of the second protrusion 461, the second end of the second connecting member 462 is connected to the first end of the second fixing member 463, the second protrusion 42 is disposed on the second end of the second protrusion 461, and the second return spring 452 is disposed on the second end of the second fixing member 463.

[0045] like Figure 4 As shown, a reset groove 224 is provided at the bottom of the lower cup lid 22, one end of the reset spring 45 is provided in the reset groove 224, and the other end is connected to the locking block.

[0046] like Figure 11 As shown, in this embodiment, the cup lid assembly 2 includes an elastic component 6, which includes an annular body 61, a protrusion 62, and a spring 63. The protrusion 62 is located on the inner circumference of the annular body 61. A limiting groove 212 is provided on the top of the inner wall of the lower cup lid 22. One end of the spring 63 is connected to the upper cup lid 21, and the other end of the spring 63 is connected to the annular body 61. The protrusion 62 is located in the limiting groove 212 and can move freely. When the cup lid assembly 2 is pressed inward toward the cup body 1, at least a portion of the locking mechanism 4 is embedded in the slot 11 of the cup body 1. The elastic component 6 and the spring 63 are both squeezed by the cup body 1 and the upper cup lid 21. When the power mechanism 3 is activated, the power mechanism 3 controls the locking mechanism 4 to disengage from the slot 11 of the cup body 1. The elastic restoring force of the elastic component 6 acts on the bottom of the upper cup lid 21, causing the cup lid assembly 2 to pop outward toward the cup body 1, completing the pop-up action, which is beneficial for the user to recognize the successful unlocking.

[0047] Preferably, there are four protrusions 62 and four springs 63, and four limiting grooves 212 are used to cooperate with the protrusions 62.

[0048] like Figure 11 As shown, in this embodiment, the water cup also includes a main board 32, a power supply 33, and a display screen 34. The motor 31, display screen 34, and power supply 33 are all electrically connected to the main board 32. The upper cup lid 21 is also provided with a switch signal receiver 7 and a light-emitting component 8, both of which are electrically connected to the main board 32. The main board 32, power supply 33, and switch signal receiver 7 are all located within the first receiving cavity 211.

[0049] Based on the above structural analysis, to improve the aesthetics and functionality of the product, the light-emitting component 8 includes a lampshade 81 and a light-transmitting ring 82. The lampshade 81 is fitted with an O-ring 83 and a side-pressure silicone 84 to enhance sealing and fixation, and is positioned above the main board 32. The lampshade 81 has a clearance hole for the anti-air switch signal receiver 7, the light-transmitting ring 82 is fitted onto the outer wall of the lampshade 81, and a cover 85 is provided on the top of the lampshade 81.

[0050] like Figures 8 to 10 As shown, in this embodiment, the light-emitting component 8 includes a lampshade 81 and a light-transmitting ring 82. The lampshade 81 is fitted with an O-ring 83 and a side-pressure silicone 84 and is disposed above the main board 32. The lampshade 81 is provided with a hole for the air-proof switch signal receiver 7. The light-transmitting ring 82 is fitted on the outer wall of the lampshade 81. The top of the lampshade 81 is provided with a cover 85.

[0051] like Figure 11 As shown, a switch signal receiver 7 and a light-emitting component 8 can also be installed on the top of the upper cup lid 21. Both are electrically connected to the main board 32. The switch signal receiver 7 is used to receive user commands. The light-emitting component 8 realizes uniform light emission in the cup mouth area and raises the position of the light emission above the desktop obstruction range, effectively avoiding the problem of light reminder failure caused by objects on the table, and significantly improving the reliability and visibility of reminders in complex desktop environments. It also includes a lampshade screw 86, used to fix the lampshade 81 and the main board 32 in the upper cup cover 21; The bottom of the lower lid 22 also includes a temperature probe 87, which is used to test the temperature of the liquid inside the cup body 1. The data is sent to the main board 32, and the temperature data is displayed on the display screen 34, which helps the drinker to observe the water temperature. like Figure 4 , Figure 15 , Figure 16As shown, the lower cup lid 22 also includes a vent hole 88, a vent plug 89, and a vent spring 90. At least a portion of the vent plug 89 is located within the vent hole 88, and the vent plug 89 is equipped with the vent spring 90 to maintain the air pressure level between the lower cup lid 22 and the cup body 1. The vent spring 90 controls the vent plug 89 to close the vent hole 88. When the power mechanism 3 is activated, the locking mechanism 4 controls the vent plug 89 to move downwards, opening the vent hole 88 and connecting the air passage of the cup body 1 and the second receiving cavity 221 to the atmosphere. When the power mechanism 3 is not operating, the vent spring 90 controls the vent plug 89 to be inserted into the vent hole 88 to close it.

[0052] Specifically, the turntable 44 of the locking mechanism 4 is driven to rotate, which puts pressure on the exhaust plug 89, causing the exhaust plug 89 to move downward, that is, to move away from the turntable 44. The exhaust plug 89 moves away from the exhaust hole 88, the exhaust hole 88 is opened, and the air passage of the cup body 1 and the air passage of the second receiving cavity 221 are connected to the atmosphere. The air pressure of the cup body 1 is equal to the atmospheric pressure. When the air pressure of the cup body 1 is equal to the atmospheric pressure, the cup lid assembly 2 can be opened or the risk can be prevented.

[0053] In this embodiment, the thickness of the bottom surface of the turntable 44 gradually decreases at the end that contacts the exhaust plug 89. The side of the turntable 44 that contacts the exhaust plug 89 forms an inclined surface, and the top of the exhaust plug 89 is hemispherical. When the turntable 44 rotates, the inclined surface presses against the exhaust plug 89, causing the exhaust plug 89 to move downward, that is, to move away from the turntable 44. The exhaust plug 89 moves away from the exhaust hole, and the exhaust hole 88 is opened. The air passage of the cup body 1 and the air passage of the second receiving cavity 221 are connected to the atmosphere, and the air pressure of the cup body 1 is equal to the atmospheric pressure. When the power mechanism 3 is not working, the turntable 44 is reset, and the exhaust spring 90 controls the exhaust plug 89 to be inserted into the exhaust hole 88 to close the exhaust hole 88.

[0054] The bottom of the lower lid 22 is provided with a silicone sealant 91 for sealing the cup opening.

[0055] like Figure 3 As shown, a tea compartment 92 is provided in the cup body 1 below the cup lid assembly 2, which is used to hold tea leaves and other items, and can be removed for cleaning.

[0056] like Figure 10 As shown, the motherboard 32 has a USB port, which is equipped with USB waterproof silicone 94.

[0057] like Figure 3 As shown, the bottom of the cup body 1 is provided with silicone feet 95 for anti-slip purposes.

[0058] like Figure 10 As shown, the top of the motor 31 is fixed by a pressure plate 96 and a pressure plate screw 97.

[0059] like Figure 8 As shown, in this embodiment, the switch signal receiver 7 is a fingerprint module, the water cup status is the water temperature, and the power supply 33 is a lithium battery.

[0060] The working principle of the water cup of this invention is as follows: In the initial state (locked state), such as Figure 6 As shown, under the elastic force of the first return spring 451 and the second return spring 452, the first locking block 43 and the second locking block 46 are pushed out of the first through hole 222 and the second through hole 223, and locked into the slot 11 of the cup body 1, thereby locking the cup lid assembly 2 and the cup body 1, and the cup lid assembly 2 cannot be opened. At the same time, under the elastic force of the exhaust spring 90, the exhaust plug 89 closes the exhaust hole 88.

[0061] When unlocking is required, the user issues a command through the fingerprint module of the switch signal receiver 7, and the motherboard 32 controls the motor 31 to start. Motor 31 drives second bevel gear 512 and transmission shaft 52 to rotate via first bevel gear 511. Spur gear 531 at the lower end of transmission shaft 52 rotates accordingly, driving turntable 44 to rotate around turntable shaft 443. Rotary blade 442 rotates, abutting against first protrusion 41 and second protrusion 42, overcoming the elastic force of return spring 45, and causing first locking block 43 and second locking block 46 to retract into second receiving cavity 221, disengaging them from the slot 11 of cup body 1, thus unlocking. Simultaneously, the elastic restoring force of spring 63 acts on upper cup lid 21, causing cup lid assembly 2 to pop outward from cup body 1. At the same time, when turntable 44 is driven to rotate, it presses against exhaust plug 89, causing exhaust plug 89 to move downward, opening exhaust hole 88. The air passage of cup body 1 and the air passage of second receiving cavity 221 are connected to the atmosphere, and the air pressure of cup body 1 is equal to the atmospheric pressure. At this time, the user can open cup lid assembly 2.
