Description

Technical Field

[0001] This utility model relates to a portable stirring cup, specifically a hand-driven rotary portable stirring cup. Background Technology

[0002] Automated equipment with stirring functions, such as coffee machines and milkshake machines, are typically large, expensive, and noisy, with poor portability. They also rely on a power source, primarily targeting commercial or home use, making them less suitable for individual users. Meanwhile, the global coffee market is expanding year by year, and coffee machines remain the mainstream coffee equipment. Besides the price barrier, coffee machines also present a technical operating barrier for users. Especially in milk frothing, coffee machines need to produce high-pressure steam and guide it to continuously impact the milk to form foam in a short time, requiring users to have considerable experience.

[0003] With market development, portable mixing cups with advantages such as small size, easy operation and portability have been gradually launched. Users can directly pour liquid into the cup and then add other liquids or powders, such as espresso liquid, espresso powder, juice, cream, milk, etc., for convenient mixing. However, there is no effective improvement solution for making milk foam.

[0004] Meanwhile, current portable blending cups typically consist of a lid assembly and a cup body. The lid assembly houses a battery-powered motor, whose output shaft connects to a stirring impeller. The motor drives the impeller to rotate at high speed to mix the liquid in the cup. However, due to the inclusion of the motor, battery, and other components, these portable blending cups are not lightweight, and users need to frequently monitor the battery level. When the battery is low, mixing is impossible. Furthermore, the existing design of blending cups has significant limitations; users need to open the lid assembly to drink from the opening in the cup body, which is inconvenient.

[0005] To address this, we propose a hand-driven rotary portable mixing cup. Utility Model Content

[0023] Compared with related technologies, the hand-driven rotary portable mixing cup provided in this application has at least the following technical advantages: By using a multi-stage planetary gear meshing mechanism between the rotating drive component and the stirring power component, the low-speed rotation of the manual drive force is converted into high-speed output, achieving efficient stirring. Furthermore, the staggered design or centrally integrated design of the stirring power component and the liquid outlet channel ensures that the power transmission and the liquid flow path do not interfere with each other.

The product requires no electricity, has a compact structure, and can be adapted to different liquid output scenarios.

[0024] Meanwhile, the stirring impeller proposed in this application can quickly stir coffee liquid without installing the foaming net holder and foaming net, meeting the mixing and preparation needs of coffee liquid. When the foaming net holder and foaming net are installed, the specific angled blades work synergistically with the foaming net, allowing the milk to pass through the tiny mesh of the foaming net under pressure. The shearing action causes air to be mixed into the milk to form milk foam. At the same time, the height design of the stirring impeller and foaming net allows the circulating vortex to fully press the milk mixed with the milk foam into the bottom of the liquid, and the highly efficient circulation cuts the milk liquid, thereby realizing the production of milk foam and quickly generating fine foam under the condition of no power supply.

[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] In related technologies, portable blending cups typically include a lid assembly and a cup body. The lid assembly houses a battery-powered motor, whose output shaft connects to a stirring impeller. The motor drives the impeller to rotate at high speed to mix the liquid in the cup. However, such portable blending cups are not lightweight due to the inclusion of components like the motor and battery, and users need to frequently monitor the battery level. When the battery is low, mixing is impossible. Furthermore, limited by motor technology, the small size of the motor results in relatively low torque, leading to a smaller diameter impeller that can be fitted and driven, resulting in lower mixing efficiency. In addition, the existing blending cup design has significant limitations; users need to open the lid assembly to drink from the opening in the cup body, which is inconvenient and fails to meet individual users' needs for lightweight, maintenance-free devices.

[0041] Therefore, constructing a purely mechanical transmission structure, utilizing manual power input and a gear speed-increasing mechanism to achieve efficient stirring, has become the preferred solution to the above problems. Furthermore, it is necessary to optimize the spatial layout of the rotary drive component and the stirring mechanism to form a compact integrated solution. Based on the above, this utility model embodiment provides a hand-driven rotary portable stirring cup, which will be described in detail below with reference to specific embodiments and accompanying drawings.

[0042] Example 1 Embodiment 1 of this utility model provides a hand-driven rotary portable stirring cup. Figure 1 This is a perspective view of a hand-driven rotary portable mixing cup according to an exemplary embodiment. Figure 2 This is one of the exploded views of a hand-operated rotary portable mixing cup structure according to an exemplary embodiment. For example... Figures 1-2 As shown, this hand-driven rotary portable stirring cup includes a cup body 10 and an upper shell 20 threadedly fitted to the open end of the cup body 10. A cup body sealing ring 40 is provided between the upper shell 20 and the open end of the cup body 10 to prevent leakage during threaded assembly. In this embodiment, the cup body 10 can be made of various materials; for example, titanium alloy can be used to consider texture and rust resistance, while environmentally friendly plastic can be used to consider cost. It also includes: A rotation drive 30 is rotatably mounted on the upper part of the upper shell 20, and has at least one internal gear ring 304 inside. A stirring power unit 50 is assembled on the upper end of the upper shell 20 and located inside the rotation drive unit 30. Its input end is engaged with the internal gear ring 304 and drives its output end to rotate faster relative to its input end. A liquid stirring component 70 has a first end connected to the output end of a stirring power component 50, and a second end extending into the inner cavity of a cup body 10 to rotate and stir the liquid contained in the inner cavity of the cup body 10.

[0043] In the above embodiment, the cup body 10 and the upper shell 20 form a detachable container structure, which is convenient for cleaning and maintenance. When the user holds the cup body 10 with one hand and rotates the rotation drive 30 with the other hand, the internal gear ring 304 drives the input end of the stirring power component 50 to rotate. Through the transmission of the stirring power component 50, the low-speed input is converted into a high-speed output, which ultimately drives the liquid stirring component 70 to rotate at high speed in the cup body 10, forming an effective stirring force, completely replacing the traditional motor drive method and meeting the needs of various liquid mixing.

[0044] Figure 3 This is an exploded view of the combined structure of the upper shell, the rotation drive member, and the stirring power member according to an exemplary embodiment. Figure 4 This is an exploded view of the structure of a stirring power unit according to an exemplary embodiment. Figure 5 This is a second exploded view of a hand-driven rotary portable mixing cup structure according to an exemplary embodiment. In this embodiment, as... Figures 3-5 As shown, the stirring power unit 50 includes an external gear frame 508, which is detachably assembled to the upper end of the upper housing 20. The internal cavity of the external gear frame 508 contains, from top to bottom, the following: The first transmission unit 501 is meshed and connected to the internal gear ring portion 304. In this embodiment, the first transmission unit 501 includes a first external gear ring 5011, which is meshed and connected to the internal gear ring portion 304. The first planetary gear carrier 502 is fixed inside the first transmission unit 501; The second transmission unit 503 includes a first internal gear ring 5031, a plurality of first planetary gears 5032 meshing with the first internal gear ring 5031, and a first sun gear 5033 disposed at the center of the first internal gear ring 5031 and meshing with the plurality of first planetary gears 5032. The upper ends of the plurality of first planetary gears 5032 and the first sun gear 5033 are all limited and mounted on the first planetary gear carrier 502. The first bracket 504 is rotatably assembled with the bottom end of the first internal gear ring 5031; The second planetary gear carrier 505 is axially positioned and fitted with the bottom end of the first sun gear 5033 so that it rotates synchronously with the first sun gear 5033. Specifically, in this embodiment, the center of the second planetary gear carrier 505 is provided with a hexagonal groove, and the bottom end of the first sun gear 5033 is provided with a hexagonal plug that matches and plugs into the hexagonal groove to achieve the positioning and fitting. The third transmission unit 506 includes a second internal gear ring 5061, a plurality of second planetary gears 5062 meshing with the second internal gear ring 5061, and a second sun gear 5063 disposed at the center of the second internal gear ring 5061 and meshing with the plurality of second planetary gears 5062. The plurality of second planetary gears 5062 are all limited and mounted on the second planetary gear carrier 505. The third gear carrier 507 is rotatably assembled with the bottom end of the second internal gear ring 5061. In this embodiment, planetary gear bearings 512 are fitted on both the first planetary gear 5032 and the second planetary gear 5062 to convert the friction in the rotational motion of the first planetary gear 5032 and the second planetary gear 5062 into low-resistance rolling friction, thereby reducing operating resistance.

[0045] In this embodiment, the first planetary gear carrier 502, the second planetary gear carrier 505, and the third gear carrier 507 are all annular brackets with planetary shaft positioning holes, forming a support structure that fixes the axial position of the planetary gear set and ensures a stable meshing relationship between the planetary gears and the sun gear.

[0046] Among them, continue to refer to Figures 3-5 The external gear set 508 includes: The outer bracket section 5081 consists of several pieces arranged in an inverted U-shape; The lower connecting section 5082, which is several in number and is arranged between adjacent outer bracket sections 5081 to form a frame; The bottom support step 5083 is formed on the inner side wall of the lower connecting section 5082 to axially limit and support the lower end of the third gear frame 507. In this embodiment, the outer circumferential edges of the first internal gear ring 5031, the first bracket 504, and the third gear carrier 507 are each formed with a plurality of locking blocks 513 that engage with the outer bracket section 5081 to restrict rotation. The locking blocks 513 on the first internal gear ring 5031, the first bracket 504, and the third gear carrier 507 are stacked vertically and abut against the inner top wall of the outer bracket section 5081 to cooperate with the bottom support step 5083 for axial positioning and assembly. In this embodiment, the engagement relationship between the outer bracket section 5081 and the locking blocks 513 restricts the circumferential rotational freedom of each transmission unit and each gear carrier. Furthermore, the vertically stacked locking blocks 513 abut against the inner top wall of the outer bracket section 5081, combined with the support of the bottom support step 5083, form a double axial limiting structure, thereby ensuring that each component maintains a stable assembly state during manual drive.

[0047] In one example, continue to refer to Figures 1-5 The first transmission unit, as the primary transmission component that receives the input from the rotating drive component 30, adopts a structure in which the first external gear ring 5011 meshes with the internal gear ring 304 to form the initial speed-up stage of power transmission. The rotation of the first external gear ring 5011 transmits the power to the second transmission unit 503 through the first planetary gear carrier 502. In the second transmission unit 503, the first planetary gear 5032 revolves around the first sun gear 5033 under the constraint of the first internal gear ring 5031, forming the first stage of acceleration output to the first sun gear 5033, and then the accelerated power is transmitted to the third transmission unit 506 through the second planetary gear carrier 505. In the third transmission unit 506, the second planetary gear carrier 505 revolves around the second sun gear 5063 under the constraint of the second internal gear ring 5061, forming a second stage of acceleration, and then the second sun gear 5063 outputs the final speed. The first bracket 504 and the third gear carrier 507 respectively support the first internal gear ring 5031 and the second internal gear ring 5061, and maintain the accelerated rotation of the first planetary gear 5032 and the second planetary gear 5062. The outer U-shaped outer bracket section 5081 of the outer gear frame 508 achieves upper axial positioning through the vertical stacking structure of the locking block part 513 and each transmission unit. The bottom support step 5083 on the inner side of the lower connecting section 5082 forms a lower axial limit with the third gear carrier 507, achieving double limiting without the need for additional fasteners, which significantly improves assembly stability.

[0048] In the above embodiment, the vertical stacking layout of the three-stage planetary gear set not only realizes multi-stage transmission in the compact internal space of the external gear set frame 508, but also eliminates radial space redundancy and axial clearance by combining the nested assembly relationship between the planetary gear set and the internal gear ring, effectively solving the technical contradiction between low transmission efficiency and loose structure in the manual drive structure; at the same time, the rotation limit of the locking block part 513 and the outer bracket section 5081, and the vertical stacking of the locking block part 513 and the bottom support step 5083 realize axial positioning assembly, and the compact layout realizes miniaturized design.

[0049] In this embodiment, please continue to refer to Appendix Figure 3 The rotation drive component 30 includes: The rotating housing 301 has several snap-fit ​​parts 302 arranged in a ring array on its annular inner wall; The inner drive ring 303 is located inside the rotating housing 301, and its annular outer wall is formed with a plurality of slots 305 that are positioned and assembled with the snap-fit ​​portion 302. The internal gear ring portion 304 is formed on the inner sidewall of the drive inner ring 303.

[0050] In the above embodiment, the rotating housing 301 is axially positioned and assembled with the slot 305 of the drive inner ring 303 through the snap-fit ​​part 302, so that the drive inner ring 303 retains only rotational freedom within the rotating housing 301. When the rotating housing 301 is manually rotated, the engagement of the snap-fit ​​part 302 and the slot 305 transmits the rotational force to the drive inner ring 303, and the internal gear ring part 304 engages with the input end of the stirring power component 50. The solution of this embodiment, through the split combination structure of the rotating housing 301 and the drive inner ring 303, reduces the processing difficulty while utilizing the multi-point insertion of the snap-fit ​​part 302 and the slot 304 to form distributed radial support, effectively improving the structural rigidity of the rotating drive component 30, ensuring that the manual driving force is efficiently transmitted to the stirring power component 50, and avoiding slippage or wobbling caused by uneven force during manual rotation.

[0051] Furthermore, a rubber sleeve can be detachably installed on the annular outer wall of the rotating housing 301. The rubber sleeve is designed to prevent slippage when the hand rotates, and various DIY patterns or reliefs can be designed to increase aesthetics and brand recognition.

[0052] In this embodiment, please continue to refer to Appendix Figure 3 The upper shell 20 includes: The shell 201 has its lower part threadedly assembled with the open end of the cup body 10, and its upper edge is provided with a number of sleeve supports 204 arranged in a ring array. A set of support pillars 204, which are distributed in a ring array at the upper edge of the housing 201, and a drive bearing 208 is provided on the rotating housing. The outer edges of the drive bearings 208 contact the annular inner wall surface of the drive inner ring 303 to support the positioning and rotation of the drive inner ring 303. In this embodiment, the number of support pillars 204 and drive bearings 208 is set to four. The waterproof step portion 205 is integrally formed on the annular outer wall of the upper part of the housing 201, and its outer diameter is the same as that of the rotating housing 301 to prevent liquid from entering the internal space of the rotating drive component 30 and contaminating the gear assembly.

[0053] In the above embodiment, when the housing 301 is manually rotated, the inner drive ring 303 rotates synchronously under the action of external force. The outer ring of the drive bearing 208 mounted on the support column 204 maintains rolling contact with the annular inner wall of the inner drive ring 303. The annular array distribution of multiple support columns 204 makes the drive bearing 208 form uniform support points along the circumference of the inner drive ring 303. The axial displacement of the inner drive ring 303 during rotation is jointly restricted by the support points of adjacent drive bearings 208, thereby providing radial support for the rotation of the inner drive ring 303. Furthermore, each drive bearing 208 independently bears the radial load. Through rolling contact, the rotational motion of the inner drive ring 303 can also be converted into low-resistance rolling friction, reducing operating resistance and preventing jamming, thereby forming a stable concentric rotation trajectory and ensuring smooth manual rotation.

[0054] In this embodiment, please continue to refer to Appendix Figure 2 The stirring power component 50 is located on one side of the upper end of the upper shell component 20. A liquid outlet pipe portion 202 forming a liquid outflow channel is formed on the other side of the upper end of the upper shell component 20. The free end of the liquid outlet pipe portion 202 passes through the rotation drive component 30 and abuts against a top cover component 60. The top cover component 60 is assembled to the upper end of the rotating housing 301. The top cover component 60 includes: The first top cover plate 601 is fixed to the upper end face of the rotating drive member 30 and has a first opening 605 that matches the free end of the liquid outlet pipe 202. A flip seat 602 is formed on the side opposite to the first opening 605. The flip cover 603 has a flip part formed on one side edge that is matched and hinged to the flip seat 602, and a cover body fastener that matches and snaps to the first top cover plate 601 and an elastic sealing cover 606 that seals the free end of the liquid outlet pipe 202 when snapped on the side away from the flip part. A push switch 604 is provided on the flip cover 603 to control the cover latch to disengage from the first top cover plate 601.

[0055] In the above embodiment, the stirring power component 50 and the liquid outlet pipe 202 are respectively placed on both sides of the upper shell 20, so that the power transmission and the liquid flow path do not interfere with each other. After passing through the rotation drive component 30, the liquid outlet pipe 202 is precisely aligned with the first opening 605 to ensure the directional flow of liquid. The flip cover 603 is opened and closed through the flip seat 602. When closed, the cover body fastener is engaged with the first top cover plate 601, and the elastic seal 606 is deformed under pressure to seal the liquid outlet of the liquid outlet pipe 202. When the press switch 604 is triggered, the cover body fastener is released, and the deformation recovery force of the elastic seal 606 assists the flip cover 603 to automatically pop open, thereby realizing the layered layout in the internal space and achieving independent control of the liquid channel while manually driving the stirring.

[0056] In this embodiment, please continue to refer to Appendix Figures 2-5 The stirring power unit 50 also includes a power conversion unit 509, which includes: The first bushing 5091 is axially limited and assembled with the bottom end of the second sun gear 5063 so that it rotates synchronously with the second sun gear 5063. Specifically, in this embodiment, the center part of the first bushing 5091 is provided with a hexagonal groove, and the bottom end of the second sun gear 5063 is provided with a first hexagonal plug that matches and plugs into the hexagonal groove to achieve the limited assembly. The first power gear 5094 is coaxially fixed to the lower end of the first bushing 5091, and a power shaft 5092 is fixed at its axial center. The output end of the power shaft 5092 passes through the axial center of the third gear carrier 507, the second sun gear 5063, the second planetary gear carrier 505, the first sun gear 5033, and the first planetary gear carrier 502 in sequence. Specifically, the upper shaft end of the first power gear 5094 is also provided with a second hexagonal plug that is adapted to the hexagonal groove on the first bushing 5091. Both the first hexagonal plug and the second hexagonal plug are inserted into the inner radial positioning of the first bushing 5091 to realize the transmission connection between the second sun gear 5063 and the first power gear 5094. The first top cover plate 601 has a shaft limiting hole 607 that matches the shaft end of the power shaft 5092. The shaft end of the power shaft 5092 passes through the shaft limiting hole 607 and is threadedly fitted with a limiting knob 80. After the upper shaft end of the power shaft 5092 passes through the shaft limiting hole 607, the limiting knob 80 is screwed onto the upper shaft end of the power shaft 5092, thus restricting the upper shaft end of the power shaft 5092 between the first top cover plate 601 and the limiting knob 80. The shaft limiting hole 607... The clearance fit between the power shaft 5092 and the limit knob 80 allows the power shaft 5092 to rotate freely, while the thread preload of the limit knob 80 can eliminate the assembly clearance and prevent the axial displacement of the power shaft 5092 caused by centrifugal force. Further optionally, a first power bearing 510 is also sleeved on the power shaft 5092, and the first power bearing 510 is rotatably assembled in the power bearing cavity 608 formed at the bottom end of the first top cover plate 601 to reduce the rotational friction of the upper shaft end of the power shaft 5092. The second power gear 5096 meshes with the first power gear 5094, and its shaft is located at the center of the cup body 10 and is provided with an extension fixing part 5098 that matches the input end of the liquid stirring component 70. In this embodiment, the first power gear 5094 and the second power gear 5096 can specifically adopt a helical gear or spur gear structure to adjust the power output direction. The upper limit wheel 5095 is coaxially fixed to the upper end of the second power gear 5096 and rotatably assembled in the limiting assembly cavity 5072 formed on the bottom wall of the third gear frame 507. One side edge of the wheel is rolledly connected to the first bushing 5091 to constrain the radial displacement of the first bushing 5091. The lower limit wheel 5097 is coaxially fixed to the lower end of the second power gear 5096 and rotatably assembled in the second assembly groove 209 opened at the upper end of the housing 201, so as to jointly constrain the radial displacement of the second power gear 5096 together with the upper limit wheel 5095. The upper end of the housing 201 has a first assembly groove 206 and a second assembly groove 209 that descend in a stepped manner. The bottom end of the second assembly groove 209 has a coaxial assembly hole 207. The bottom end of the first power gear 5094 is coaxially mounted with a limit bearing 5093. The limit bearing 5093 is rotatably mounted in the first assembly groove 206, and the inner ring of the limit bearing 5093 is coaxially fixed with the power shaft 5092 to reduce transmission friction. The lower limit wheel 5097 is rotatably mounted in the second assembly groove 209, and part of the outer edge of the limit bearing 5093 extends to the side and above the lower limit wheel 5097 to form axial positioning and prevent the second power gear 5096 from axially displacing. The extended fixing part 5098 is located at the position of the assembly hole 207. It also includes a bottom cover 5099, which is movably sleeved on the extension fixing part 5098 and fixedly assembled at the bottom end of the mounting hole 207 to close the mounting hole 207 and prevent liquid from entering the internal space of the rotating drive 30 and contaminating the gear assembly.

[0057] In the above embodiment, when the hand-drive force of the rotating drive member 30 is transmitted to the stirring power member 50 through the internal gear ring 304, the second sun gear 5063 outputs the accelerated rotational power to the first bushing 5091. The first bushing 5091 drives the first power gear 5094 to rotate. Through the meshing of the first power gear 5094 and the second power gear 5096, the rotation position is changed to be located at the central axis of the cup body 10. Subsequently, the second power gear 5096 transmits the power to the liquid stirring member 70 located at the center of the cup body 10, so that the stirring impeller 702 rotates around the central axis of the cup body 10. Furthermore, the upper limit wheel 5095 is distributed on one side of the first bushing 5091, and constrains the radial offset of the first bushing 5091 through rolling contact to avoid gear meshing misalignment. At the same time, the lower limit wheel 5097, together with the upper limit wheel 5095, constrains the radial displacement of the second power gear 5096. The stepped first assembly groove 206 and the second assembly groove 209 allow the components of the power conversion component 509 to be embedded in the housing 201 in layers. The depth of the first assembly groove 206 is smaller than that of the second assembly groove 209, forming an axial assembly space difference. While ensuring that the meshing surfaces of the two gears do not interfere with the rolling surfaces of the two limit wheels, the vertical through structure of the assembly hole 207 is used to achieve the center positioning of the second power gear 5096, reducing the cumulative error of multi-plane assembly.

[0058] In summary, the above-mentioned technical solution of this application, through the gear meshing and limiting structure of the power conversion component 509, converts the output position of the side-mounted power source into the axial center position of the cup body, realizing efficient power transmission from the side-mounted power source to the center of the cup body. On the one hand, it solves the problem of low space utilization of the cup lid caused by the central arrangement of the power component in the traditional structure, freeing up layout space for other functional components on the cup lid. On the other hand, it also realizes the precise positioning of the multi-stage transmission structure in a compact space, avoiding transmission failure caused by gear meshing misalignment, while reducing assembly complexity.

[0059] In this embodiment, please continue to refer to Appendix Figures 3-5 A plurality of inner ring bearings 306 arranged in an annular array are rolled on the annular inner wall of the upper part of the inner ring 303 to support the positioning and rotation of the inner ring 303. The inner ring bearings 306 are all rotatably mounted on the inner ring bearing positioning part 609 formed on the bottom wall of the first top cover plate 601. In this embodiment, the number of inner ring bearings 306 is set to three. The inner ring bearing positioning part 609 is a cylindrical structure to be mounted on the inner ring of the inner ring bearing 306.

[0060] In the above embodiment, when the inner ring 303 is manually rotated, the inner gear ring 304 drives the first outer gear ring 5011 to rotate through meshing to form an initial power transmission path. At this time, the inner ring bearing 306 cooperates with the inner ring bearing positioning part 609 at the bottom of the first top cover plate 601 to form a distributed rolling support structure and reduce friction loss, thereby applying a radial constraint force to the drive inner ring 304 in the vertical direction to prevent the drive inner ring 304 from swaying due to uneven force. At the same time, it can also cooperate with the lower distributed rolling support structure of the drive bearing 208 to jointly maintain the stable rotation of the inner gear ring 304.

[0061] In this embodiment, please continue to refer to Appendix Figure 2 The liquid stirring component 70 includes: The stirring rod 701 has its first end fixedly assembled with the extension fixing part 5098. In this embodiment, the axial middle part of the first end of the stirring rod 701 is provided with a slot that matches the extension fixing part 5098 so that the extension fixing part 5098 can be inserted into the slot for fixation, thereby achieving rigid fixation of the power transmission path. The stirring impeller 702 is disposed at the second end of the stirring rod 701 and includes a plurality of stirring blades 7021 arranged in an annular array and an impeller ring body 7022 fixed to the outer edge of the stirring blades 7021. The impeller ring body 7022 is used to limit the deformation of the blades under high-speed rotation and improve the overall rigidity.

[0062] In the above embodiment, the stirring rod 701 transmits the rotational motion output by the second power gear 5096 to the stirring impeller 702. During the rotation, the stirring blade 7021 applies radial and axial shear forces to the liquid, guiding the liquid to form a continuous flow path along the stirring blade 7021, causing the liquid in the cup 10 to form a vortex, thereby enhancing the liquid circulation efficiency.

[0063] In summary, the hand-driven rotary portable stirring cup provided by this utility model embodiment transforms the low-speed rotation of the hand-driven force into high-speed output through the multi-stage planetary gear meshing mechanism of the rotation drive component 30 and the stirring power component 50, achieving efficient stirring. Furthermore, the stirring power component 50 and the liquid outlet pipe 202 are staggered on the upper shell 20, achieving a layered layout in the internal space, so that the power transmission and liquid flow path do not interfere with each other. While manually driving the stirring, the liquid channel can be independently controlled, allowing users to conveniently drink the liquid contained in the cup body 10.

[0064] Example 2 The difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 of this utility model also provides another hand-driven rotary portable stirring cup. Figure 6 This is a perspective view of a hand-driven rotary portable mixing cup according to another exemplary embodiment. Figure 7 This is one of the exploded views of a hand-driven rotary portable mixing cup structure according to another exemplary embodiment. Figure 8 This is an exploded view of the combined structure of the upper shell, the rotation drive member, and the stirring power member according to another exemplary embodiment. Figures 6-8 As shown, the stirring power unit 50 is located in the middle of the upper shell 20. A tube insertion hole 210 is formed in the middle of the upper shell 20, and a rigid suction tube is inserted into the tube insertion hole 210. The other end of the rigid suction tube passes through the rotation drive unit 30 and a top cover 60 in sequence. The top cover 60 is assembled to the upper end of the rotating housing 301. The top cover 60 includes: The second top cover plate 610 is disposed on the upper end face of the rotating drive member 30, and has a plurality of top cover buckle holes 611 at its upper end, and has a tube positioning hole 612 coaxially disposed with the tube insertion hole in its middle part. Among them, the upper outer wall of the outer bracket section 5081 is formed with a bracket buckle part 5085 that matches and snaps with the top cover buckle hole 611 to fix the second top cover plate 610. The bracket buckle part 5085 is fixed by the buckle between the top cover buckle hole 611 and the bracket buckle part 5085 without the need for screws or adhesives, which makes it easy for users to disassemble and clean. The rigid suction tube passes sequentially through the axial positions of the third gear carrier 507, the second sun gear 5063, the second planetary gear carrier 505, the first sun gear 5033, and the first planetary gear carrier 502, and is fixedly assembled with the second sun gear 5063. Further optionally, a second power bearing 511 is sleeved on the rigid suction tube, and the second power bearing 511 is rotatably assembled in the power bearing cavity 608 formed at the bottom end of the second top cover plate 610, so as to reduce the rotational friction of the upper shaft end of the rigid suction tube and cooperate to axially position the rigid suction tube.

[0065] In the above embodiments, the central arrangement of the stirring power component 50 on the upper shell 20, compared to the side arrangement in Embodiment 1, can fully utilize the internal space of the upper shell 20, thereby reducing the lateral dimensions and making the overall structure more compact. The coaxial design of the insertion positioning hole 612 and the insertion hole 210 ensures that the rigid straw maintains a straight path when passing through the multi-layer gear assembly, avoiding transmission jamming due to offset. This application achieves space reuse of the transmission component and liquid suction channel through the central integrated design of the rigid straw and the stirring power component 50. The rigid straw is also located at the axial position of the liquid stirring component 70, which not only realizes the liquid suction function, but also uses the rigid straw as the positioning reference of the transmission component, significantly improving space utilization and enhancing the portability and user experience of the portable stirring cup.

[0066] Figure 9 This is an exploded view of the mixing power component structure according to another exemplary embodiment. Figure 10 This is a second exploded view of a hand-operated rotary portable mixing cup structure according to another exemplary embodiment. (See attached diagram.) Figures 9-10 In this embodiment, the first transmission unit 501 includes: The power planetary gears 5012 are numerous and arranged in a circular array. Each of the power planetary gears 5012 is meshed and connected to the internal gear ring 304. In this embodiment, there are three power planetary gears 5012. The second external gear ring 5013 is located at the center of several power planetary gears 5012 and meshes with each other for transmission. In this embodiment, a number of inner ring bearings 306 are rolled on the annular inner wall of the upper part of the inner cavity of the inner ring 303 to support the positioning and rotation of the inner ring 303. The inner ring bearings 306 and the power planetary gear 5012 are coaxially assembled and rotatably assembled on the inner ring bearing positioning part 609 formed on the bottom wall of the second top cover plate 610. In this embodiment, the inner ring bearing positioning part 609 is a hollow circular sleeve to accommodate the inner ring bearings 306.

[0067] In the above embodiment, when the user manually rotates the drive inner ring 303, its internal gear ring 304 drives the power planetary gear 5012 to revolve around the second external gear ring 5013 while rotating on its own axis, so as to transmit power to the subsequent transmission unit. The meshing structure between the power planetary gear 5012 and the second external gear ring 5013 can also amplify the input speed. Furthermore, the inner ring bearing 306 forms a rolling support between the drive inner ring 303 and the second top cover plate 610, reducing frictional resistance and preventing the drive inner ring 303 from shifting at high speed, thereby improving the stability and durability of the transmission system.

[0068] In this embodiment, please continue to refer to Appendix Figure 7 The liquid stirring component 70 includes: The stirring rod 701 is hollow inside, and its first end is integrally formed with the rigid straw in the axial direction; The stirring impeller 702 is disposed at the second end of the stirring rod 701 and includes a plurality of stirring blades 7021 arranged in an annular array and an impeller ring body 7022 fixed to the outer edge of the stirring blades 7021.

[0069] In the above embodiment, the stirring rod 701 and the rigid straw are integrally formed, that is, the two can be combined into one part, jointly undertaking the dual functions of liquid output and rotation. The stirring rod 701 transmits the rotational motion output by the second power gear 5096 to the stirring impeller 702. During the rotation, the stirring blade 7021 applies radial and axial shear force to the liquid, guiding the liquid to form a continuous flow path along the stirring blade 7021, causing the liquid in the cup 10 to form a vortex, and enhancing the liquid circulation efficiency.

[0070] Other undescribed structures are described in Example 1.

[0071] In summary, the hand-driven rotary portable stirring cup provided by this utility model embodiment transforms the low-speed rotation of the hand-driven force into high-speed output through the multi-stage planetary gear meshing mechanism of the rotating drive component 30 and the stirring power component 50, achieving efficient stirring. Furthermore, the centrally integrated design of the rigid straw and the stirring power component 50 realizes the spatial reuse of the transmission component and the liquid suction channel, ensuring that the power transmission and the liquid flow path do not interfere with each other. While manually driving the stirring, the independent control of the liquid channel is achieved, allowing users to conveniently drink the liquid contained in the cup body 10.

[0072] Example 3 Embodiment 3 of this utility model provides a fixing structure for the stirring power component 50 in a hand-driven rotary portable stirring cup. (Continue referring to...) Figure 3 In this hand-driven rotary portable mixing cup, the outer wall of the lower connecting section 5082 is recessed with an assembly groove, and the upper end surface of the upper shell 20 is formed with several locking points 203 that engage with the assembly groove to fix the mixing power component 50. In this embodiment, the number of locking points 203 is three and they are evenly distributed in the upper circumferential direction of the upper shell 20 to balance the force.

[0073] For other undescribed structures, refer to Example 1 or Example 2.

[0074] In summary, in the technical solution provided by Embodiment 3 of this utility model, the snap-fit ​​method of the assembly groove and the locking point 203 realizes the fixation of the stirring power component 50 on the upper shell 20. Specifically, when the stirring power component 50 is installed on the upper shell 20, the assembly groove of the lower connecting section 5082 is aligned with the locking point 203 of the upper shell 20 and pressure is applied. The locking point 203 is embedded in the assembly groove to form an interference fit, thereby restricting the axial and radial movement of the stirring power component 50, greatly simplifying the assembly process, and realizing rapid installation and disassembly.

[0075] Example 4 Embodiment 4 of this utility model provides another fixing structure for the stirring power component 50 in a hand-driven rotary portable stirring cup. (Continue referring to...) Figure 8 In this hand-driven rotary portable mixing cup, the outer wall surface of the lower connecting section 5082 is formed with a threaded portion 5084, and the upper end surface of the upper shell 20 is formed with a threaded sleeve portion 209 that is threadedly assembled and positioned with the threaded portion 5084 to fix the mixing power component 50.

[0076] For other undescribed structures, refer to Example 1 or Example 2.

[0077] In summary, in the technical solution provided by Embodiment 4 of this utility model, the threaded method in which the threaded part 5084 and the threaded sleeve part 209 cooperate to fix the stirring power component 50 on the upper shell 20; specifically, the external gear frame 508 is aligned with the threaded sleeve part 209 of the upper shell 20 and rotated until the external gear frame 508 is completely pressed against the upper end face of the upper shell 20. The axial preload generated by the helical meshing restricts the axial and radial movement of the stirring power component 50. When disassembling, the external gear frame 508 can be separated by rotating it in the opposite direction, which greatly simplifies the assembly process and realizes quick installation and disassembly.

[0078] Example 5 Embodiment 5 of this utility model provides a rapid foaming structure for a hand-driven rotary portable stirring cup. A foaming net bracket 703 is detachably mounted on the bottom end of the stirring impeller 702, and a foaming net 704 is fixed on the foaming net bracket 703, so that the liquid in the cup body 10 is quickly foamed when the stirring blade 7021 guides the liquid through the mesh of the foaming net 704; In actual milk foam making, the quality of milk foam depends on two aspects. The first is the fineness, that is, the size of the bubble diameter, which needs to be solved by continuous cutting. However, the technical difficulty lies in high-efficiency cutting and cyclic cutting to ensure that all milk foam eventually reaches a certain fineness. The second is the degree of integration between air and milk. Ideally, milk foam will be evenly distributed in milk. However, since milk foam is gas, if it is not interfered with, it will form clumps and float on the top of the milk, producing a layering phenomenon, that is, milk is milk and foam is foam. Although it does not affect drinking, it cannot meet the user's need for latte art on coffee.

[0079] The solution is to adjust the height of the stirring impeller 702 and the foaming net 704. Since the stirring impeller 702 and the foaming net 704 in this design already have powerful circulation and refining functions, it is only necessary to adjust them to the appropriate height and angle to fully press the milk foam into the bottom of the liquid and form a circulation for thorough blending.

[0080] In this embodiment, the stirring blade 7021 has a preset tilt angle of 15° to 45°, the diameter of the stirring blade 7021 is 1 / 2 to 4 / 5 of its inner diameter in the vertical position of the inner cavity of the cup body 10, and the height of the stirring blade 7021 is located in the inner cavity of the cup body 10 corresponding to the liquid level of 50ml to 150ml, so as to adapt to the amount of milk required to make milk foam for a cup of coffee under normal conditions; the mesh diameter of the foaming net 704 is 0.1mm to 0.3mm; in this embodiment, the foaming net 704 is made of stainless steel mesh.

[0081] In summary, in the technical solution provided by Embodiment 5 of this utility model, when the stirring impeller 702 rotates, the stirring blades 7021 push the liquid at a preset angle to form a vortex. Without the foaming net holder 703 and foaming net 704 installed, the coffee liquid can be quickly stirred to meet the mixing requirements. When the foaming net holder 703 and foaming net 704 are installed, when the stirring impeller 702 rotates, the stirring blades 7021 push the milk liquid at a preset angle to form a vortex. Under pressure, the milk liquid passes through the tiny mesh of the foaming net 704, and the mesh edges shear the milk liquid, allowing air to mix in, thus quickly generating fine milk foam. The technical solution of this application, through the synergistic effect of the blades at a specific angle and the microporous foaming net, quickly generates fine foam under power-free conditions, achieving a foaming effect similar to that of a high-temperature steam method in a coffee machine. Furthermore, it requires no user experience and has a low technical operating threshold. At the same time, the detachable structure of the foaming net holder facilitates cleaning and replacement of the foaming net holder 703 and foaming net 704.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
