Description

Technical Field

[0001] This invention relates to the technical field of ice shavers, and in particular to an ice shaver. Background Technology

[0002] Ice shavers, as specialized equipment for cutting ice, are widely used in daily life, catering, and leisure consumption. They can be divided into two categories based on their power source: manual and electric. Manual ice shavers rely on human power to drive the blades to rotate and cut ice; they have a simple structure and low cost, making them suitable for small-scale production and parent-child interactive scenarios. Electric ice shavers, on the other hand, use an electric motor as a power source, driving the cutting components through a transmission mechanism. They offer high efficiency and convenience, meeting large-scale ice-making needs. With consumption upgrades and the expansion of family entertainment scenarios, their market penetration rate is continuously increasing.

[0003] Currently, there is an irreconcilable contradiction between the tightness of connections and the ease of disassembly in the technical design of existing ice shavers. On the one hand, in pursuit of stable connections during operation, some products adopt deep threaded connections, multiple sets of bolts for fastening, or interference fits. While these designs can effectively resist vibration and impact during the cutting process and prevent components from loosening, disassembly requires tools or complex operations, which is time-consuming and laborious. Users find it difficult to disassemble and separate the parts that come into contact with the ice for cleaning, and can only perform a general rinse. However, a general rinse is insufficient to thoroughly clean the parts that come into contact with the ice, leaving cleaning dead spots. Residual water and sugar from the rinse can easily lead to bacterial growth inside the ice shaver. On the other hand, to simplify the disassembly process, some products use simple snap-fit ​​or magnetic quick-connect structures. While this allows for quick loading and unloading of the slicing components, the locking strength of these structures is limited. When the slicing components rotate at high speed to cut ice, centrifugal force and vibration can easily cause the connections to loosen, or even lead to component displacement or detachment, posing safety hazards and failing to meet the requirements for continuous and stable cutting.

[0004] In summary, there is a need for an ice shaver that provides stable connection during operation and is easy to disassemble for cleaning. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of the prior art and provide an ice shaver that is stable in operation and easy to disassemble for cleaning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An ice shaver includes: The host computer is provided with an assembly interface and a rotary drive component, the rotary drive component being located inside the assembly interface; A shredding assembly includes an outer fixed cylinder and an inner rotating cylinder. The outer fixed cylinder is fixed at the assembly interface. The inner rotating cylinder is placed inside the outer fixed cylinder and rotatably connected to it. A connector is provided at the bottom of the inner rotating cylinder. The connector and the inner rotating cylinder are interlocked. A connecting shaft is fixed on the end face of the connector and connected to the rotary drive component. Several shredding blades are fixed on the side wall of the inner rotating cylinder. The shredding blades are circumferentially distributed on the side wall of the inner rotating cylinder. A feeding channel communicating with the interior of the outer fixed cylinder is provided on the side wall of the outer fixed cylinder. An extension port is located at the bottom of the inner rotating cylinder. The connector is installed inside the extension port and rotatably engaged with it. A circumferential baffle is fixed on the outer wall of the connector, located at one end near the connecting shaft. The width of the circumferential baffle is greater than the diameter of the extension port. Several latches are fixed on the inner wall of the extension port, circumferentially distributed on the inner wall of the extension port. The outer wall of the connector is provided with latch slots corresponding to the latches, located at one end away from the connecting shaft. The latches and latch slots are interlocked. One side wall of the latch slot is provided with a matching latch position, and the latches and the latch position are interlocked. The other side wall of the latch slot is provided with a latch ejection guide slope, and the latches and the latch ejection guide slope are slidably connected.

[0007] The assembly interface on the main unit is used to fix the outer fixed cylinder shell of the shredding assembly. The rotating drive component inside precisely aligns with the connecting shaft on the end face of the connector, thereby driving the inner rotating cylinder placed inside the outer fixed cylinder shell to rotate stably. In use, ice material is fed into the equipment through the feeding channel on the side wall of the outer fixed cylinder shell. The shredding blades distributed circumferentially on the side wall of the inner rotating cylinder rotate at high speed with the inner rotating cylinder, cutting the ice material to form uniform ice shreds. The extension port at the bottom of the inner rotating cylinder and the connector adopt a rotating fastening structure. After the circumferential lock on the inner wall of the extension port is inserted into the lock socket of the connector, when the rotating drive component rotates forward, the lock will slide along the inner wall of the socket to the corresponding fastening position and fasten with each other, realizing automatic locking of the shredding assembly and ensuring the connection stability between the inner rotating cylinder and the connector during the cutting process. When the rotating drive component rotates in reverse, the lock will slide along the push-out guide slope on the other side of the lock socket to disengage from the fastening position, completing automatic unlocking and facilitating disassembly and cleaning. The circumferential baffle on the outer wall of the connector, being wider than the extension opening diameter, effectively restricts the axial displacement of the connector, preventing loosening during assembly. This application utilizes a large-angle locking structure design, enabling forward locking and reverse unlocking of the shredding assembly without additional manual operation. This makes component placement and removal more convenient, significantly improving operational ease of use. The detachable design between the connector and the inner rotating cylinder allows for easy replacement of the connector, facilitating maintenance. This locking structure also ensures stable fixation of the shredding assembly during operation, preventing the inner rotating cylinder from rotating out. This eliminates the need for additional cup lid fasteners and accessories, simplifying the equipment assembly process and effectively saving manufacturing costs.

[0008] Preferably, a pusher rod is provided on the inner side of the feeding channel. The pusher rod is adapted to and movably connected to the feeding channel. A weight-reducing groove is provided on the end face of the pusher rod away from the inner rotating cylinder, and several protrusions are fixed on the end face of the pusher rod facing the inner rotating cylinder. Through the design of the pusher rod, ice material can be actively pushed towards the inner slicing disc, improving shaved ice efficiency. The weight-reducing groove on the pusher rod can reduce its own weight and operating force while ensuring the structural strength of the pusher rod. The protrusions on the pusher rod can enhance the contact friction with the ice material, prevent the ice material from slipping, and thus achieve a smooth and precise push of the ice material towards the slicing disc.

[0009] Preferably, the slicing disc has several slicing holes, and slicing blades are installed at the slicing holes, with the slicing blades fixed to the outer surface of the slicing disc. When the inner rotating cylinder rotates at high speed with the rotating drive, the slicing disc on its side wall rotates synchronously. After the ice material to be processed is pushed to the slicing disc, the slicing blades fixed to the outer surface of the slicing disc cut the ice material, so that the ice material is sliced ​​into ice shreds of uniform size through the slicing holes.

[0010] Preferably, a discharge rib is fixed on the inner wall of the inner rotating cylinder, and an auxiliary discharge slope is provided on the side of the discharge rib facing the central axis of the inner rotating cylinder. The auxiliary discharge slope is inclined towards the central axis of the inner rotating cylinder from the end near the cylinder opening to the end away from the cylinder opening. The thickness of the discharge rib gradually increases from the end near the cylinder opening to the end away from the cylinder opening. When the inner drum rotates at high speed, the discharge bone on its inner wall rotates synchronously. The ice material cut by the shaving disc comes into contact with the auxiliary discharge slope on the side of the discharge bone facing the central axis under the action of centrifugal force. The slope is inclined from the opening of the inner drum towards the bottom of the drum towards the central axis, and the thickness of the discharge bone gradually increases from the opening to the bottom of the drum. This can form a continuous rotational pushing force to guide the ice material along the slope to the outside of the inner drum and push it towards the discharge port. The inclined slope and the gradually thickening structure improve the pushing and guiding effect of the ice material, effectively avoiding the accumulation and blockage of ice material in the drum, realizing smooth discharge of ice shavings, and ensuring the discharge efficiency and the continuity of cutting operation.

[0011] Preferably, the inner rotating cylinder has a slicing blade mounting port on its side wall, and two opposite side walls of the slicing blade are provided with rib grooves. A rib matching the rib groove is fixed at the edge of the slicing blade mounting port, and the rib and the rib groove are interlocked. A clip head and a card are fixed on the other two opposite side walls of the slicing blade, and a clip head positioning groove matching the clip head and a card positioning groove matching the card are provided at the edge of the slicing blade mounting port. The clip head and the clip head positioning groove are interlocked, and the card and the card positioning groove are interlocked. When assembling the shredder disc, align and engage the two sides with the retaining rib grooves with the retaining ribs on the edge of the shredder disc mounting opening on the inner rotating drum side wall. Then, align and engage the other two sides with the retaining heads and cards with the corresponding retaining head positioning grooves and card positioning grooves on the edge of the mounting opening. This four-fold engagement positioning assembly method securely fixes the shredder disc to the inner rotating drum, achieving both rapid and precise assembly of the shredder disc and ensuring connection stability during high-speed rotation and cutting through the multi-directional engagement structure. This effectively prevents the disc from shifting or loosening. Furthermore, this engagement structure facilitates disassembly, cleaning, and replacement of the shredder disc later, improving the convenience of equipment maintenance.

[0012] Preferably, a plurality of fasteners are fixed on the outer wall of the outer fixed shell. These fasteners are circumferentially distributed on the outer wall of the outer fixed shell, and are located at one end of the outer fixed shell. The inner side of the assembly interface has a fastener slot that matches the fastener. The outer fixed shell is installed at the assembly interface and locked in place by the cooperation of the fasteners and the fastener slot. A discharge guide plate is fixed at the other end of the outer fixed shell. During assembly, the end of the outer fixed shell with the fasteners is aligned with the assembly interface of the main unit, so that the plurality of fasteners circumferentially distributed at the port of the outer fixed shell precisely align with the fastener slot on the inner side of the assembly interface and are locked in place. This achieves rapid assembly and stable connection between the outer fixed shell and the main unit, ensuring that the outer fixed shell does not loosen or shift during ice shaving operations. Quick assembly and disassembly can be completed without additional fasteners, simplifying the assembly process and improving assembly efficiency. The discharge guide plate at the other end of the outer fixed shell guides and diverts the cut ice during the ice shaving operation, allowing the cut ice to be discharged smoothly in a preset direction, preventing the ice from scattering and improving the convenience and cleanliness of use.

[0013] Preferably, the rotary drive component includes a PCBA control board and a motor. The PCBA control board and the motor are electrically connected. The motor has a motor shaft, and one end of the connecting shaft has a motor shaft slot. The motor shaft and the motor shaft slot are interlocked. The end face of the connector has a connecting shaft slot that matches the other end of the connecting shaft. The other end of the connecting shaft and the connecting shaft slot are interlocked with each other and have an interference fit. One end of the connecting shaft is precisely interlocked with the connecting shaft slot on the end face of the connector, forming an interference fit, so that the two are assembled into a single structure. While the outer fixed shell is being assembled with the assembly interface, the other end of the connecting shaft is also precisely interlocked with the motor shaft through the motor shaft slot. During operation, the PCBA control board, which is electrically connected to the motor, regulates the motor. The motor's operation drives the motor shaft to rotate, which in turn drives the inner rotating cylinder to rotate synchronously through the transmission action of the integrated connecting shaft and connector.

[0014] Preferably, a limiting plate is fixed on the inner wall of the outer fixed shell. The limiting plate is located near one end of the outer fixed shell. The limiting plate has a bearing mounting hole, and a bearing is installed in the bearing mounting hole. The bearing is sleeved on the connecting shaft. The side wall of the connecting shaft has a bearing retaining ring limiting groove, and a bearing retaining ring is sleeved in the bearing retaining ring limiting groove. The bearing is located between the bearing retaining ring and the connecting head. During assembly, the bearing is sleeved on the connecting shaft and placed in the bearing mounting hole. Then, the bearing retaining ring is sleeved in the bearing retaining ring limiting groove on the side wall of the connecting shaft, so that the bearing is axially limited between the bearing retaining ring and the connecting head. During operation, the bearing rotates smoothly with the connecting shaft and provides radial support and positioning for the connecting shaft.

[0015] Preferably, the limiting plate is provided with a bearing outer ring limiting groove, which is located on one side of the port of one end of the fixed cylindrical shell facing outwards. The bearing outer ring limiting groove is located at the edge of the port of the bearing mounting hole, and the outer ring of the bearing is placed in the bearing outer ring limiting groove. The inner ring of the bearing is located inside the bearing mounting hole. A positioning pin is fixed in the bearing outer ring limiting groove, and the outer ring of the bearing is provided with a positioning hole that matches the positioning pin. The positioning pin and the positioning hole are interlocked. During assembly, the bearing is sleeved on the connecting shaft and placed in the bearing mounting hole of the limiting plate, so that the outer ring of the bearing is engaged in the bearing outer ring limiting groove. At the same time, the positioning pin in the limiting groove is precisely inserted into the positioning hole on the outer ring of the bearing. The inner ring of the bearing is placed inside the bearing mounting hole. During operation, the inner ring of the bearing rotates synchronously with the connecting shaft, while the outer ring is fixed and kept stationary by the bearing outer ring limiting groove and the positioning pin.

[0016] Preferably, the connector is positioned on one side of the port at the other end of the fixed cylinder shell, directly opposite the limiting plate. A wear-resistant sealing gasket limiting step is provided on the end face of the connector facing the limiting plate. A wear-resistant sealing gasket is fitted onto the limiting step, and the bearing mounting hole is located inside the wear-resistant sealing gasket. During assembly, the wear-resistant sealing gasket is fitted onto the limiting step, and the connector is positioned on one side of the port at the other end of the fixed cylinder shell, with the wear-resistant sealing gasket sandwiched between the two. Simultaneously, the bearing mounting hole is located inside the wear-resistant sealing gasket. The wear-resistant sealing gasket reduces rotational friction loss between the connector and the limiting plate, and effectively prevents ice and moisture from entering the bearing mounting hole through the gap between them, thus improving the wear resistance of the components and the overall sealing performance of the equipment, extending the service life of the equipment.

[0017] The beneficial effects of this invention are: ensuring the connection stability between the inner rotating cylinder and the connector during the cutting process; facilitating disassembly and cleaning; enabling forward rotation locking and reverse rotation unlocking of the shaving assembly without additional manual operation, making component placement and removal more convenient and significantly improving operational ease of use; allowing easy replacement of the connector, thus facilitating maintenance; ensuring the inner rotating cylinder remains fixed during operation, eliminating the need for additional cup lid fasteners and accessories, simplifying the equipment assembly process and effectively saving production costs; achieving stable and precise pushing of ice material to the shaving disc; effectively preventing ice material from accumulating and blocking inside the cylinder, achieving smooth material discharge in shaved ice operations, while ensuring material output efficiency and the continuity of cutting operations; and providing precise support and positioning for the connecting shaft on the connector.

Then, the bearing retaining ring 41 is fitted into the bearing retaining ring limiting groove 40 of the connecting shaft 6 to form an axial limit on the bearing 39.

[0037] IV. Assembly between the shredding assembly and the main unit 1 The outer fixed shell 3 is engaged with the buckle slot 30 inside the assembly interface 2 of the main unit 1 through the buckle 29 distributed circumferentially at its port. At the same time, the connecting shaft 6 is also engaged with the motor shaft 34 on the motor 33 through the motor shaft slot 35, thus completing the overall assembly.

[0038] Working principle: During operation, the motor shaft 34 drives the connecting head 5 to rotate synchronously at high speed with the inner rotating drum 4 via the connecting shaft 6. After the user puts the ice material into the feeding channel 8, they push the push rod 15. The protrusions 17 on the push rod 15 enhance the friction with the ice material, smoothly and accurately pushing the ice material towards the inner rotating drum 4. The rotation of the inner rotating drum 4 drives the shredding disc 7 to rotate synchronously. The shredding blades 19 on the outer surface of the shredding disc 7 cut the ice material, so that the ice material is formed into ice shreds of uniform size through the shredding holes 18. At the same time, the discharge bone 20 on the inner side wall of the inner rotating drum 4 rotates with it. With the help of the auxiliary discharge slope 21 and the gradually thickening structure, a rotational pushing force is formed. Under the cooperation of centrifugal force, the ice shreds are guided to the outside of the inner rotating drum 4 and smoothly discharged through the discharge guide plate 31 at the port of the outer fixed cylinder shell 3, avoiding material blockage.

[0039] During the entire working process, when the rotating drive component rotates forward, the locking structure of the extension port 9 and the connector 5 automatically locks to ensure a stable connection. After the work is completed, the motor reverses to allow the locking buckle 11 to slide out of the locking buckle guide slope 14 along the locking buckle, thereby achieving automatic unlocking. This facilitates the disassembly and assembly of components and greatly improves the ease of operation and the practicality of the equipment.
