Description

Technical Field

[0001] This application relates to the field of ice shavers, and more particularly to a reset rotating device and an ice shaver. Background Technology

[0002] As an essential piece of equipment for making cold drinks in summer, the smooth operation of the core components of an ice shaver is crucial. Traditional ice shavers generally use a worm gear structure, where the rotation of the worm gear drives the claw disc to move downwards while rotating, thus completing the ice shaving operation. However, after shaving, the worm gear needs to be rotated in the opposite direction to move the worm along the axial direction, allowing the claw disc to return to its initial height for the next operation.

[0003] In this process, the worm gear is driven to rotate by the rotating shaft, which in turn drives the worm to move axially. The rotating shaft is usually directly fitted inside the bushing, and the two rely on lubricating oil for lubrication to reduce friction. However, if there is insufficient oil in the bushing or the equipment has not been used for a long time, the rotating shaft may jam due to increased friction during rotation, making it unable to drive the worm gear to rotate smoothly. Consequently, the worm and its end claw disc cannot return to their initial position. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0054] 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 application, "multiple" means two or more, unless otherwise explicitly specified.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0057] After using the ice shaver, to restore the claw disc at the end of the worm gear to its initial height, the shaft needs to be rotated to drive the worm wheel to rotate. The worm wheel, in turn, moves the worm gear upward, thus restoring the claw disc to its initial height. However, the existing shaft and bushing are usually directly fitted together, and lubricating oil is applied between the bushing and the shaft for lubrication. But if there is a lack of lubricating oil or the lubricating oil deteriorates over time, the friction between the shaft and the bushing will increase, which may cause jamming during the rotation of the shaft.

[0058] In view of the above problems, this application provides a reset rotation device, the reset rotation device 100 including a rotating shaft 110, a bushing 120, a first bearing 131, a pressure plate 140, a handle 150 and a second bearing 132.

[0059] In some embodiments, the bushing 120 is sleeved on the rotating shaft 110, the bushing 120 has a mounting cavity 121, the first bearing 131 is disposed on the circumferential surface of the rotating shaft 110, the first bearing 131 is located between the inner wall of the mounting cavity 121 and the outer wall of the rotating shaft 110, the second bearing 132 is disposed on the outer circumferential surface of the end of the rotating shaft 110, the pressure plate 140 is disposed at the end of the rotating shaft 110, the second bearing 132 is located at the end of the rotating shaft 110 away from the pressure plate 140, and the handle 150 is detachably mounted on the pressure plate 140, the handle 150 drives the rotating shaft 110 to rotate through the pressure plate 140.

[0060] See Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the bushing 120 has an internal mounting cavity 121. The bushing 120 is first fitted onto the outer surface of the rotating shaft 110, so that a portion of the rotating shaft 110 is located inside the bushing 120. Multiple first bearings 131 are installed on the outer surface of the rotating shaft 110, located inside the mounting cavity 121. It can be understood that the first bearing 131 has an inner ring and an outer ring, with balls between the inner and outer rings. At this time, the outer ring of the first bearing 131 is in close contact with the inner wall of the mounting cavity 121, and the inner ring of the first bearing 131 is assembled and connected to the outer surface of the rotating shaft 110. That is, when the rotating shaft 110 needs to be rotated, since the outer surface of the rotating shaft 110 does not directly contact and rub against the bushing 120, the rotating shaft 110 no longer needs lubricating oil. The first bearings 131 are sufficient to allow the rotating shaft 110 to rotate relative to the bushing 120, thereby preventing the rotating shaft 110 from jamming during rotation.

[0061] Please continue reading. Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the second bearing 132 is mounted on the frame of the ice shaver, thereby limiting the radial square position of the end of the rotating shaft 110, making the rotating shaft 110 more stable during rotation, and thus preventing the worm gear 500 from shifting position during rotation.

[0062] Furthermore, to facilitate manual rotation of the rotating shaft 110, a pressure plate 140 is installed at the end of the rotating shaft 110. The pressure plate 140 is connected to the rotating shaft 110 for transmission, and a handle 150 is installed on the pressure plate 140. When it is necessary to rotate the rotating shaft 110, the power is transmitted to the rotating shaft 110 by hand through the cooperation of the handle 150 and the pressure plate 140, thereby driving the rotating shaft 110 to rotate.

[0063] In this embodiment, the number of the first bearings 131 is X, which satisfies X≥2. It can be understood that the two first bearings 131 are arranged on the outer circumferential surface of the rotating shaft 110, which can make the rotating shaft 110 more stable when it rotates.

[0064] An elastic element 160 is also sleeved on the rotating shaft 110. One end of the elastic element 160 abuts against the bushing 120, and the end of the elastic element 160 away from the bushing 120 abuts against the pressure plate 140. A fastening adjustment element 170 is also installed at the end of the rotating shaft 110. The end of the fastening adjustment element 170 near the pressure plate 140 abuts against the pressure plate 140.

[0065] In one embodiment, the pressure plate 140 is connected to the rotating shaft 110 via a key. The key connection enables the pressure plate 140 to rotate synchronously with the rotating shaft 110, but does not restrict the movement of the pressure plate 140 in the axial direction of the rotating shaft 110.

[0066] See 2. Figure 3 , Figure 5 as well as Figure 6As shown, the worm gear 500 is mounted on the rotating shaft 110. To increase the force exerted by the worm gear 500 on the worm 400, the friction generated by the contact between the side of the pressure plate 140 and the side of the fastening adjustment member 170 prevents the rotating shaft 110 from rotating, thereby increasing the resistance of the worm gear 500 on the worm 400. Specifically, the pressure plate 140 is pressed against the fastening adjustment member 170 by the elastic member 160, thereby increasing the force between the pressure plate 140 and the fastening adjustment member 170. The increased force between the pressure plate 140 and the fastening adjustment member 170 further increases the resistance between them. The friction between them will also increase, thereby increasing the force required for the rotating shaft 110 to rotate. It is understood that there is also friction between the end of the elastic element 160 and the pressure plate 140, and there is also friction between the other end of the elastic element 160 and the bushing 120. If the elastic element 160 is compressed, the force between the elastic element 160 and the pressure plate 140 and the force between the elastic element 160 and the bushing 120 will increase, and the friction between the elastic element 160 and the pressure plate 140 and the friction between the elastic element 160 and the bushing 120 support will increase.

[0067] In one embodiment, the fastening adjustment member 170 is a nut. It is understood that the outer surface of the end of the rotating shaft 110 has external threads, the nut is screwed onto the end of the rotating shaft 110, and the surface of the nut facing the pressure plate 140 abuts against the pressure plate 140. Specifically, the fastening adjustment member 170 can be a wing nut.

[0068] In this embodiment, the elastic element 160 can be a compression spring.

[0069] The bushing 120 also has a receiving cavity 122, and the elastic member 160 abuts against the axial end face of the receiving cavity 122, with the elastic member 160 partially extending into the receiving cavity 122.

[0070] Please continue reading. Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, the end of the bushing 120 facing the pressure plate 140 is provided with a receiving cavity 122, and the end of the elastic member 160 facing away from the pressure plate 140 abuts against the end face of the receiving cavity 122, thereby realizing the contact between the elastic member 160 and the bushing 120.

[0071] In one embodiment, the handle 150 includes a transmission rod 151 detachably connected to the pressure plate 140, and a handwheel 152 is provided at the end of the transmission rod 151 away from the pressure plate 140.

[0072] See Figures 1 to 3As shown, in order to facilitate manual driving of the rotating shaft 110, a transmission rod 151 is detachably installed on the outer circumference of the pressure plate 140, and a handwheel 152 is installed at the end of the transmission rod 151 away from the pressure plate 140. By cranking the handwheel 152, the pressure plate 140 is driven to rotate, and the transmission rod 151 transmits force to the pressure plate 140. Under the transmission of the key connection between the pressure plate 140 and the rotating shaft 110, the rotating shaft 110 is driven to rotate.

[0073] In another embodiment, the handle 150 includes at least one threaded hole 153 formed on the outer peripheral surface of the pressure plate 140, wherein a drive rod 154 is mounted in the threaded hole 153.

[0074] See Figure 4 , Figure 5 and Figure 6 As shown, a threaded hole 153 is directly opened on the outer peripheral surface of the pressure plate 140, and a drive rod 154 is installed in the threaded hole 153. When driving the rotating shaft 110 to rotate, the drive rod 154 can be held by hand to directly drive the pressure plate 140 to rotate. Under the transmission action of the key connection between the pressure plate 140 and the rotating shaft 110, the drive rod 154 can drive the rotating shaft 110 to rotate at the same time as driving the pressure plate 140 to rotate. Specifically, there are two threaded holes 153 and two drive rods 154, which are evenly distributed on the outer peripheral surface of the pressure plate 140.

[0075] This application also provides an ice shaver, which includes a frame, a reset and rotation device 100 as described above, a drive device 200, a sleeve 300, a worm gear 400, a worm wheel 500, a claw plate 600, and a shaver assembly 700.

[0076] Specifically, the reset rotation device 100 is mounted on the frame, the drive device 200 is disposed on the frame, the sleeve 300 is fixedly mounted on the frame, the worm 400 is partially located inside the sleeve 300, and the worm 400 is connected to the drive device 200 in a transmission engagement. The drive device 200 drives the worm 400 to rotate and move along a preset direction. The worm wheel 500 is fixedly mounted on the rotating shaft 110 of the reset rotation device 100, and the worm wheel 500 is connected to the worm 400 in a transmission engagement. The claw disc 600 is fixedly mounted on the end of the worm 400, and the planer assembly 700 is mounted on the frame, with the planer assembly 700 located in the movement path of the claw disc 600.

[0077] See Figure 7 and Figure 8As shown, the worm gear 500 is fixedly installed on the end face of the rotating shaft 110 away from the handle 150. The sleeve 300 is fixedly installed on the frame and is hollow. Furthermore, a through groove is opened on the outer surface of the sleeve 300, which communicates with the interior of the sleeve 300. The worm 400 is placed inside the sleeve 300 and is connected to the drive device 200. The worm gear 500 is connected to the worm 400 at the position of the through groove. Specifically, under the action of the sleeve 300 and the drive device 200, the worm 400 can also move downward during rotation, thereby driving the claw plate 600 to move towards the planer assembly 700 so that the claw plate 600 contacts the ice block located at the position of the planer assembly 700, thereby driving the ice block to rotate, and then the planer assembly 700 cuts the ice block to achieve ice shaving.

[0078] In one embodiment, the claw disk 600 is circular, and the surface of the claw disk 600 facing the blade assembly 700 has a plurality of conical needles (not shown in the figure). The conical needles can be inserted into the ice block and drive the ice block to rotate together with the claw disk 600. Furthermore, the blade assembly 700 is located directly below the claw disk 600, so that the conical needles can be inserted into the ice block after the claw disk 600 descends to a certain distance.

[0079] The driving device 200 includes a rotary driving component 210 and a transmission structure 220. The transmission structure 220 is connected to the rotary driving component 210. The transmission structure 220 includes a pulley 221. A transmission groove 222 is formed on the outer surface of the worm 400. The transmission groove 222 is arranged along the axial direction of the worm 400. A pin 223 is provided on the pulley 221. The pin 223 is partially located in the transmission groove 222.

[0080] See Figure 8 and Figure 9 As shown, the rotary drive 210 drives the pulley 221 to rotate via a belt. In order to synchronously drive the worm 400 to rotate, a transmission groove 222 is opened on the outer surface of the worm 400, and the transmission groove 222 is set along the axial direction of the worm 400. A pin 223 is fixedly installed on the pulley 221, which partially extends into the transmission groove 222. The pin 223 limits the worm 400 in the circumferential direction, but does not restrict the axial movement of the worm 400. Therefore, with the cooperation of the transmission groove 222 and the pin 223, the pulley 221 can synchronously drive the worm 400 to rotate. Furthermore, with the cooperation of the worm wheel 500 and the worm 400, the worm 400 can also drive the pawl 600 to move downward along the axis while rotating.

[0081] In this embodiment, the rotary drive component 210 is a motor or electric motor, etc.

[0082] Please continue reading. Figure 8 and Figure 9 As shown, in order to prevent the pin 223 from separating from the transmission groove 222, a bolt is also installed on the pulley 221 to fix the position of the pin 223, so that the end of the pin 223 is always in the transmission groove 222, preventing the pin 223 from leaving the transmission groove 222.

[0083] Understandably, when the worm 400 and the claw plate 600 move downwards a certain distance, if they need to return to their initial positions, the handle 150 is rotated to rotate the shaft 110, which in turn drives the worm 400 upwards via the worm wheel 500, thus restoring the worm 400 and the claw plate 600 to their initial height.

[0084] The planer assembly 700 includes a cutter head 710, a cutter body 720, and a positioning plate 730. The cutter body 720 is fixedly mounted on the cutter head 710, and the positioning plate 730 is detachably mounted on the end face of the cutter head 710 facing the claw plate 600.

[0085] See Figure 10 As shown, when the claw disc 600 contacts the ice block located on the cutter disc 710, the ice block is subjected to a downward pressure and a rotational force. A blade 720 is installed on the cutter disc 710. When the ice block, which moves downward and rotates, contacts the blade 720, the blade 720 will cut the ice block, thereby achieving ice shaving. Furthermore, in order to prevent the ice block from shifting during rotation and thus failing to shave the ice, a positioning disc 730 is installed on the upper surface of the cutter disc 710. The ice block is placed in the positioning disc 730, and the positioning disc 730 limits the position of the ice block to prevent it from shifting.

[0086] The planer assembly 700 further includes a snap-fit ​​assembly 740, which is used for detachable installation of the positioning plate 730 and the cutter head 710. The snap-fit ​​assembly 740 includes multiple latches 741 on the end face of the positioning plate 730 facing the cutter head 710. Each latch 741 has a latching groove 742. The surface of the cutter head 710 facing the claw plate 600 has multiple through clearance grooves 743. A protrusion 744 is provided on one side of each clearance groove 743. The protrusion 744 is located on the surface of the cutter head 710 facing away from the claw plate 600.

[0087] See Figure 10 , Figure 11 as well as Figure 12As shown, in this embodiment, the buckle 741 is L-shaped, and a slot 742 is provided on the horizontal part of the buckle 741. It can be understood that the buckle 741 can deform to a certain extent when subjected to external force. The positioning disk 730 is detachably connected to the cutter head 710 through the snap-fit ​​assembly 740. Specifically, multiple evenly spaced clearance slots 743 are provided on the surface of the cutter head 710. A protrusion 744 is provided on one side of each clearance slot 743. The protrusion 744 is located on the back of the buckle 741. When installing the positioning disk 730, the buckle 741 first passes through the clearance slot 743, and then the positioning disk 730 is rotated to move the slot 742 to the position of the protrusion 744. At this time, the protrusion 744 is placed in the slot 742 to achieve snap-fit. If it is necessary to disassemble the positioning disk 730, simply rotate the positioning disk 730 in the opposite direction to separate the protrusion 744 from the slot 742.
