Description

Technical Field

[0001] This utility model relates to the field of ice shaver technology, specifically to an ice-pressing drive anti-detachment adjustment structure for an ice shaver. Background Technology

[0002] Chinese utility model patent CN202323664460.8 discloses a hand-cranked ice shaver. The crank handle has a small bevel gear meshing with a large bevel gear. When the crank handle is cranked, the small bevel gear rotates synchronously with the shaft, driving the large bevel gear to rotate. When the large bevel gear rotates, the drive disc, blade holder, and locking disc rotate synchronously. When in use, the user adds ice cubes to the cylinder, where the ice cubes contact the blade holder at the bottom of the cylinder, pressing the ice cubes firmly to ensure full contact. Then, the user cranks the handle and drives the blade holder to rotate. As the blade holder rotates, the blades on it shave ice from the ice cubes, which then fall from the bottom of the cylinder. However, when the blade holder presses down on the ice, the ice generates a reaction force on the blade holder. This reaction force is transmitted through the blade holder to the large bevel gear, causing it to shift upwards. This, in turn, causes the small bevel gear to tilt upwards and bounce, affecting the transmission stability between the large and small bevel gears. In severe cases, it can even cause them to disengage and become unable to transmit power. Therefore, further improvements are necessary. Utility Model Content

[0003] The present invention aims to provide an ice-pressing drive anti-detachment adjustment structure for an ice shaver, in order to overcome the shortcomings of the prior art.

[0004] An ice-pressing drive anti-detachment adjustment structure for an ice shaver designed for this purpose includes a main body, on which an ice-pressing component, a manual drive component, and a downward pressure adjustment component are provided. The manual drive component includes a manual drive element, a manual transmission gear, and a manual engagement gear. The downward pressure adjustment component includes a downward pressure adjustment element and a downward pressure element. The manual drive element is positioned and rotated on the main body and is driven and connected to the manual transmission gear. The manual transmission gear meshes and drives the manual engagement gear. The downward pressure adjustment element is rotatably mounted on the main body and is driven and connected to the downward pressure element. The downward pressure element moves on the main body through the drive of the downward pressure adjustment element, and when it moves, it drives the manual transmission gear to move in the direction of the manual engagement gear.

[0005] The manual transmission gear has a ring on its side, and the pressing part has a transition part and an arc-shaped part on opposite sides. The pressing adjustment part rotates with the transition part, and the arc-shaped part abuts against the ring.

[0006] The pressure adjustment assembly also includes a pressure bracket, which is fixedly mounted on the main body and has a bracket clearance hole and a movable cavity. The movable cavity has an opening facing the annulus. The pressure adjustment component passes through the bracket clearance hole and rotates with the adapter. The pressure component is located inside the movable cavity and extends and retracts outside the movable cavity opening through the drive of the pressure adjustment component.

[0007] The pressure bracket is also provided with a positioning concave arc edge, a positioning rotating shaft is provided on the side of the ring, and a positioning ring is provided on the outside of the positioning rotating shaft. The positioning concave arc edge is respectively limited and matched with the positioning rotating shaft, the ring, and the positioning ring.

[0008] The main body includes a housing and a top cover that are fixedly fitted together. The bottom of the housing has a housing opening and the side has a side opening. The ice pressing component extends and retracts on the housing opening at least partially through the drive of the manual drive component. One end of the manual drive component is connected to the manual transmission gear, and the other end extends out of the side opening and is connected to a drive handle. The top cover has a top cover opening corresponding to the pressing adjustment component, and a cover is detachably mounted on the top cover opening.

[0009] The main body is also equipped with a motor drive assembly.

[0010] The ice pressing assembly includes a worm gear, an ice pressing disc, and an ice pressing drive gear. The ice pressing disc can be detached and installed at the lower end of the worm gear, and the ice pressing drive gear is driven by the worm gear.

[0011] The motor drive assembly meshes with the ice-pressing transmission gear, while the manual drive assembly alternately drives with the worm gear.

[0012] The ice-pressing transmission gear rotates on the main body through the meshing of the motor drive component, and drives the worm gear to rotate together during rotation. The worm gear descends on the main body through the action of the manual drive component during rotation.

[0013] The worm gear moves linearly up or down on the main body via alternating drives of the manual drive assembly.

[0014] The worm gear is provided with a worm groove, which is recessed into the outer wall of the worm gear along the axis of the worm gear. The ice pressing transmission gear is provided with a connecting hole at the center and is sleeved on the worm gear through the connecting hole. An ice pressing drive part is provided on the connecting hole. The ice pressing drive part extends into the worm groove and slides along the trajectory of the worm groove. The ice pressing transmission gear meshes with the motor drive assembly through the gear part provided on the periphery.

[0015] The motor drive assembly includes a drive motor, a reduction gear set, and a reduction gear set housing. The reduction gear set housing is fixedly installed inside the main body. The drive motor is installed on the reduction gear set housing, and its drive end is connected to the reduction gear set. The reduction gear set is installed inside the reduction gear set housing and meshes with the gear part around the ice pressing transmission gear.

[0016] The reduction gear set housing or main body is equipped with a worm limit switch, which is connected to the drive motor electronic control. The worm is provided with a worm limit part, and when the worm descends to the end position, it touches the worm limit switch through the worm limit part.

[0017] The worm gear is provided with helical teeth, which are spirally arranged around the periphery of the worm gear. When the manual engagement gear rotates, it is driven by the helical teeth through the gear part on the periphery, so as to drive the worm gear to rise or fall on the main body. The worm gear is driven by the motor drive assembly to rotate unidirectionally on the main body. When the worm gear rotates, the helical teeth engage with the gear part on the periphery of the manual engagement gear to realize the rotation and descent of the worm gear on the main body.

[0018] This invention utilizes the meshing transmission between a manual transmission gear and a manual engagement gear, allowing the manual drive component to drive the ice-pressing assembly to rise or fall when rotated. Furthermore, the drive connection between the adjusting lowering component and the lowering component allows the lowering component to drive the manual transmission gear towards the manual engagement gear. This allows users to adjust the meshing position between the manual transmission gear and the manual engagement gear according to their needs, making the meshing transmission more efficient. Moreover, the lowering component can clamp the manual transmission gear, effectively preventing tooth disengagement due to the ice-pressing reaction force of the ice-pressing assembly, thus ensuring the stability of the meshing transmission between the manual engagement gear and the manual transmission gear.

[0029] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] See Figures 1-10 The ice-pressing drive anti-detachment adjustment structure of this ice shaver includes a main body, on which an ice-pressing component, a manual drive component, and a pressure adjustment component are provided. The manual drive component includes a manual drive component 28, a manual transmission gear 29, and a manual engagement gear 30. The pressure adjustment component includes a pressure adjustment component 36 and a pressure component 37. The manual drive component 28 is positioned and rotated on the main body and is drivenly connected to the manual transmission gear 29. The manual transmission gear 29 engages with the manual engagement gear 30 for transmission. The pressure adjustment component 36 is rotatably mounted on the main body and is drivenly connected to the pressure component 37. The pressure component 37 moves on the main body through the drive of the pressure adjustment component 36 and drives the manual transmission gear 29 to move in the direction of the manual engagement gear 30 when it moves.

[0032] The manual transmission gear 29 and the manual engagement gear 30 are meshed together, allowing the manual drive component 28 to drive the ice pressing assembly to rise or fall when rotated. Furthermore, the drive connection between the pressure adjustment component 36 and the pressure component 37 allows the pressure component 37 to drive the manual transmission gear 29 towards the manual engagement gear 30. This allows the user to adjust the meshing position between the manual transmission gear 29 and the manual engagement gear 30 according to their needs, making the meshing transmission more efficient. The pressure component 37 also clamps and presses the manual transmission gear 29, effectively preventing tooth disengagement between the manual engagement gear 30 and the manual transmission gear 29 due to the ice-pressing reaction force of the ice pressing assembly, thus ensuring the stability of the meshing transmission between the manual engagement gear 30 and the manual transmission gear 29.

[0033] The manual transmission gear 29 has a ring 29.1 on its side. The pressing member 37 has a connecting part 37.1 and an arc-shaped part 37.2 on opposite sides. The pressing adjustment member 36 rotates with the connecting part 37.1, and the arc-shaped part 37.2 abuts against the ring 29.1.

[0034] Since the transition part 37.1 and the arc-shaped part 37.2 are respectively provided on opposite sides of the pressing member 37, when the pressing adjustment member 36 rotates the transition part 37.1 on one side of the pressing member 37, it can drive the arc-shaped part 37.2 on the other side of the pressing member 37 to abut against the ring 29.1, thereby performing a clamping action to press the manual transmission gear 29. At the same time, it can also drive the manual transmission gear 29 to move in the direction of the manual meshing gear 30 to adjust the meshing transmission position between the manual transmission gear 29 and the manual meshing gear 30.

[0035] Because of the meshing transmission position between the manual transmission gear 29 and the manual engagement gear 30, misalignment and jamming problems that may occur during assembly or meshing can be effectively avoided.

[0036] The pressure adjustment assembly also includes a pressure bracket 38, which is fixedly mounted on the main body and has a bracket clearance hole 38.1 and a movable cavity 38.2. The movable cavity 38.2 has an opening facing the annulus 29.1. The pressure adjustment member 36 passes through the bracket clearance hole 38.1 and is rotatably engaged with the adapter 37.1. The pressure member 37 is located inside the movable cavity 38.2 and extends and retracts outside the movable cavity opening through the drive of the pressure adjustment member 36.

[0037] The pressure bracket 38 is fixed to the main body by fasteners or buckles. The pressure component 37 is a wear-resistant component and is located in the movable cavity 38.2 during assembly. The arc-shaped part 37.2 of the pressure component 37 extends and retracts outside the opening of the movable cavity during adjustment and abuts against the ring 29.1 during extension and retraction.

[0038] The pressure bracket 38 is also provided with a positioning concave arc edge 38.3, the side of the ring 29.1 is provided with a positioning pivot 29.2, and the outside of the positioning pivot 29.2 is provided with a positioning ring 29.3. The positioning concave arc edge 38.3 is respectively limited and engaged with the positioning pivot 29.2, the ring 29.1 and the positioning ring 29.3.

[0039] Specifically, the positioning concave arc edge 38.3 is semi-circular arc-shaped, and the main body is provided with a semi-circular arc-shaped mating part at the corresponding position. The positioning concave arc edge 38.3 and the semi-circular arc-shaped mating part are respectively limited to the positioning rotating shaft 29.2. The opposite sides of the positioning concave arc edge 38.3 and the semi-circular arc-shaped mating part are respectively limited to the ring 29.1 and the positioning ring 29.3, so that the manual transmission gear 29 is limited to rotate between the positioning concave arc edge 38.3 and the semi-circular arc-shaped mating part.

[0040] The main body includes a housing 31 and a top cover 32 that are fixedly fitted together. The housing 31 has a housing opening 31.1 at the bottom and a side opening 31.2 on the side. The ice pressing component is at least partially extended and retracted on the housing opening 31.1 by a manual drive component. One end of the manual drive component 28 is driven and connected to the manual transmission gear 29, and the other end extends out of the side opening 31.2 and is connected to a drive handle 34. The top cover 32 has a top cover opening 32.1 corresponding to the pressing adjustment component 36. A cover 39 is detachably mounted on the top cover opening 32.1.

[0041] The drive handle 34 allows the user to easily operate the manual drive component 28. The top cover opening 32.1 can be covered or opened by removing and installing the cover 39. After the top cover opening 32.1 is opened, the user can use a tool to apply pressure to the pressure adjustment component 36 to drive the pressure adjustment component 36 to rotate.

[0042] The main body is also equipped with a motor drive component.

[0043] The ice pressing assembly includes a worm gear 20, an ice pressing plate 21, and an ice pressing transmission gear 22. The ice pressing plate 21 can be detached from the lower end of the worm gear 20, and the ice pressing transmission gear 22 is drivenly connected to the worm gear 20.

[0044] The motor drive assembly meshes with the ice-pressing transmission gear 22 for transmission, while the manual drive assembly alternately drives the worm gear 20.

[0045] The ice-pressing transmission gear 22 rotates on the main body through the meshing of the motor drive assembly, and drives the worm gear 20 to rotate together during rotation. The worm gear 20 descends on the main body through the action of the manual drive assembly during rotation.

[0046] The worm gear 20 moves linearly up or down on the main body via the alternating drive of the manual drive assembly.

[0047] By utilizing the meshing transmission between the motor drive assembly and the ice-pressing transmission gear 22, and the alternating drive cooperation between the manual drive assembly and the worm gear 20, the motor drive assembly can drive the worm gear 20 to rotate and descend on the main body during operation. The manual drive assembly can drive the worm gear 20 to linearly rise or fall on the main body during operation. This allows the ice-pressing disc 21 to complete the pressing and shaving of ice blocks and its reset. Compared with the prior art, the meshing method ensures that the ice-pressing disc 21 effectively presses the ice blocks during operation and does not have the problem of jumping up and down, thus improving the shaving effect of the ice blocks. In addition, the manual drive assembly can ensure that the ice-pressing assembly can be reset to the initial position for the user to perform the next shaving operation, thereby improving the user experience.

[0048] The worm 20 is provided with a worm groove 20.1, which is recessed into the outer wall of the worm 20 along the axis of the worm 20. The ice pressing transmission gear 22 is provided with a connecting hole 22.1 at its center and is sleeved on the worm 20 through the connecting hole 22.1. An ice pressing drive part 22.2 is provided on the connecting hole 22.1. The ice pressing drive part 22.2 extends into the worm groove 20.1 and slides along the trajectory of the worm groove 20.1. The ice pressing transmission gear 22 meshes with the motor drive assembly through the gear part provided on the periphery.

[0049] The motor drive assembly includes a drive motor 23, a reduction gear set 24, and a reduction gear set housing. The reduction gear set housing is fixedly installed inside the main body. The drive motor 23 is installed on the reduction gear set housing, and its drive end is connected to the reduction gear set 24. The reduction gear set 24 is installed inside the reduction gear set housing and meshes with the gear part around the ice pressing transmission gear 22.

[0050] The worm 20 is provided with helical teeth 20.3, which are spirally arranged around the periphery of the worm 20. When the manual engagement gear 30 rotates, it is driven to move the worm 20 up or down on the main body by interleaving the gear part on its periphery with the helical teeth 20. The worm 20 rotates unidirectionally on the main body by the drive of the motor drive assembly. When the worm 20 rotates, the helical teeth 20.3 are helically engaged with the gear part on the periphery of the manual engagement gear 30 to realize the rotation and descent of the worm 20 on the main body.

[0051] Specifically, the user can rotate the manual drive component 28 by applying force to it. When the manual drive component 28 rotates, it drives the manual transmission gear 29 to rotate on the main body as well. When the manual transmission gear 29 rotates, it is interleaved with the manual engagement gear 30, thereby driving the manual engagement gear 30 to rotate on the main body as well. When the manual engagement gear 30 rotates, its outer gear part can interleave with the helical teeth 20.3, thereby driving the worm gear 20 to rise or fall linearly on the main body to compress the ice and to raise and reset the entire ice pressing assembly.

[0052] When the drive motor 23 is working, its drive end reduction gear set 24 meshes to drive the reduction gear set 24 to rotate within the reduction gear set housing. When the reduction gear set 24 rotates, it meshes with the gear part around the ice pressing transmission gear 22, thereby driving the ice pressing transmission gear 22 to rotate on the main body. Since the ice pressing drive part 22.2 extends into the worm groove 20.1, the ice pressing transmission gear 22 drives the worm 20 to rotate on the main body as well. In addition, since the gear part around the manual engagement gear 30 and the helical teeth 20.3 are interlocked and the manual engagement gear 30 is not in operation at this time, the rotating worm 20 can descend on the main body and press the ice block by helically engaging the gear part around the manual engagement gear 30 through the helical teeth 20.3.

[0053] The reduction gear set housing includes an upper gear set housing 25 and a lower gear set housing 26. The upper gear set housing 25 and the lower gear set housing 26 are fixedly fitted together and form a housing cavity between them. A housing notch 25.1 is provided on the upper gear set housing 25 or the lower gear set housing 26. The housing notch 25.1 communicates with the housing cavity. The reduction gear set 24 is disposed in the housing cavity and at least partially extends out of the housing notch 25.1, and meshes with the gear part of the periphery of the ice pressing transmission gear 22 for transmission.

[0054] The upper housing 25 and lower housing 26 of the gear set are fixed to each other by snaps or fasteners. The drive motor 23 is fixed to the upper housing 25 of the gear set by fasteners, and its drive end extends into the housing cavity and is connected to a motor gear. The motor gear meshes with the reduction gear set 24 for transmission. A housing notch 25.1 is provided on one side of the upper housing 25 of the gear set so that a part of the reduction gear set 24 is placed outside the housing cavity, so as to realize the meshing transmission between the reduction gear set 24 and the gear part around the ice pressing transmission gear 22.

[0055] A worm limit switch 27 is provided on the housing or main body of the reduction gear set. The worm limit switch 27 is electrically connected to the drive motor 23. A worm limit part 20.2 is provided on the worm 20. When the worm 20 descends to the end position, it touches the worm limit switch 27 through the worm limit part 20.2.

[0056] Specifically, the gear set upper housing 25 is also fixedly mounted with a motor control board 33 by means of snaps or fasteners. The motor control board 33 is electrically connected to the worm limit switch 27 and the drive motor 23 respectively. The worm limit switch 27 is fixed to the gear set upper housing 25 by means of snaps or fasteners. The worm limit part 20.2 is located at the top of the worm 20. When the worm 20 descends to the end position, the worm limit part 20.2 touches the worm limit switch 27. At this time, the worm limit switch 27 sends a signal to the motor control board 33 that the worm 20 has descended to the end position, so that the motor control board 33 controls the drive motor 23 to stop working.

[0057] The axis of the ice pressing transmission gear 22 is parallel to the axis of the reduction gear set 24. The axis of the ice pressing transmission gear 22 is perpendicular to the axis of the manual engagement gear 30. The axis of the manual engagement gear 30 is parallel to the axis of the manual transmission gear 29. The worm gear 20, the ice pressing plate 21 and the ice pressing transmission gear 22 are set on the same axis.

[0058] This allows the worm gear 20, the ice pressing plate 21, and the ice pressing transmission gear 22 to rotate on the same axis, with the ice pressing transmission gear 22 rotating parallel to the axis of the reduction gear set 24, and the manual transmission gear 29 and the manual engagement gear 30 rotating perpendicularly to the axis of the reduction gear set 24.

[0059] The top cover 32 is provided with a top cover guide post 32.1, which corresponds to the housing opening 31.1. The worm gear 20 is provided with a worm gear guide hole 20.4 at its center. The top cover guide post 32.1 is guided and movably sleeved on the worm gear guide hole 20.4. The worm gear 20 extends and retracts on the housing opening 31.1 through the cooperation of the worm gear guide hole 20.4 and the top cover guide post 32.1.

[0060] The housing 31 and the top cover 32 are fixed to each other by snaps or fasteners. The lower end of the worm gear 20 extends out of the housing opening 31.1 and is detachably connected to the ice pressing plate 21. The cooperation between the worm gear guide hole 20.4 and the top cover guide post 32.1 can ensure that the worm gear 20 moves linearly up or down.

[0061] The housing 31 is also provided with a pressing member 35, which is pressed onto the ice pressing transmission gear 22 so that the ice pressing transmission gear 22 rotates on the housing 31 at a designated position, thereby ensuring the drive connection between the ice pressing assembly and the motor drive assembly and the manual drive assembly respectively.

[0062] The lower end of the worm gear 20 is provided with a worm gear buckle 20.5. The ice pressing plate 21 is located below the main body and its upper surface is provided with several screw fasteners 21.1. The several screw fasteners 21.1 are arranged in a ring at intervals along the center of the ice pressing plate 21. The ice pressing plate 21 is rotatably and detachably fastened to the worm gear buckle 20.5 through the screw fasteners 21.1.

[0063] The rotational assembly direction of the screw fastener 21.1 and the worm gear fastener 20.5 is the same as the rotational direction of the ice pressing plate 21, so that the screw fastener 21.1 and the worm gear fastener 20.5 can be effectively assembled when the ice pressing plate 21 rotates, preventing the worm gear 20 from loosening from the ice pressing plate 21. At the same time, since the ice pressing plate 21 can be removed, it is convenient for users to clean and maintain it daily.

[0064] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
