Description

Technical Field

[0001] The present disclosure relates to an anti-slip component of an ice cream machine and the ice cream machine. Background Art

[0002] Prior art, such as the Chinese invention patent application document with publication number CN117752007A, discloses a control method for an ice cream machine. In this technology, a first output shaft and a second output shaft are provided through the motor. The first output shaft is connected to the knife shaft by a belt transmission, and the second output shaft is connected to the screw nut by a planetary gear set.

[0003] Based on the above, the transmission connection between the existing planetary gear set and the screw nut is a rigid connection. This rigid connection structure is used in a single-motor driven ice cream machine. The technical problem it has is that due to the use of a single motor, when working, the rotation of the cutter head to shave ice will inevitably drive the cutter head to move downward synchronously. When the depth of the cutter head shaving ice does not reach the preset descent height of the cutter head, the cutter head will be blocked by the ice and cannot move downward. At this time, the screw assembly cannot be raised and lowered normally, and the cutter head cannot continue to move downward, which will cause the drive motor to stall or even be damaged.

[0004] In the prior art, in order to prevent the motor from stalling, the motor current or the motor temperature is detected. When the current is too large or the motor temperature is too high, the motor is shut down for protection. This method of preventing stalling will cause the entire ice cream machine to stop working. Although this protection method can save the machine, it cannot complete the normal production process, seriously affecting the user experience.

[0005] At the same time, in the prior art, in an ice shaving process, when the upper body moves between the first position and the second position, the upper body relies on the first microswitch and the second microswitch to respectively determine whether the upper body has reached the first position and the second position, and then controls the motor to stop driving the lifting assembly. The technical problem with this control method is that when the first microswitch or the second microswitch fails and is damaged, the circuit board of the ice cream machine cannot receive the position information of the upper body. In this case, when the upper body reaches the first position or the second position, the motor will continue to drive the lifting assembly to operate. At this time, the lifting assembly is always running, and the upper body has moved to the maximum stroke. At this time, the upper body is forcibly driven, and the entire body will be broken. There is even a safety hazard of accidentally injuring the user when the body is broken.

[0034] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other unless there is any conflict.

[0035] It should be noted that when a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

[0036] See also Figures 1 to 13 An ice cream maker 100 of the present disclosure is described.

[0037] like Figures 1 to 3 As shown, the ice cream machine 100 includes a lower shell 10 , an upper shell 20 , a cutter 30 , a driving structure (not shown), a lifting component 70 and a container 1 .

[0038] The upper housing 20 is movably mounted to the lower housing 10. The container 1 is removably placed in the lower housing 10. A drive mechanism is mounted on the upper housing 20. A lifting member 70 is mounted on both the upper housing 20 and the lower housing 10 and is connected to the drive mechanism. Driven by the drive mechanism, the lifting member 70 drives the upper housing 20 to move up and down relative to the lower housing 10. The cutter 30 is removably mounted to the drive mechanism within the upper housing 20. Driven by the drive mechanism, the cutter 30 rotates and is driven by the lifting member 70 to move longitudinally relative to the container 1, thereby moving the cutter 30 up and down.

[0039] The lower housing 10 is used to install the container 1 so as to install the container 1 at a position below the cutter 30. The upper housing 20 is movably installed on the lower housing 10.

[0040] The driving structure includes a driving portion 40, a first transmission component 50 and a second transmission component 60. Figure 2 and Figure 3 As shown, the drive unit 40 is preferably a brushless DC motor that can stably drive the first transmission component 50 and the second transmission component 60, thereby ensuring that the rotational motion and vertical lifting motion of the tool 30 are performed at uniform speeds. The drive unit 40, the first transmission component 50, and the second transmission component 60 are mounted within the upper housing 20. Specifically, the drive unit 40 is fixedly mounted to the upper housing 20, while the first transmission component 50 and the second transmission component 60 are rotatably mounted to the upper housing 20 and connected to the output shaft 410 of the drive unit 40, thereby outputting power from the drive unit 40 to the first transmission component 50 and the second transmission component 60.

[0041] The input end 51a of the first transmission component 50 (gearbox 51) is connected to the output shaft 410 of the drive unit 40. The second output end 53b of the first transmission component 50 is connected to the lifting component 70. Power is delivered to the lifting component 70 via the second output end 53b in a manner that varies the rotational speed. The lifting component 70 is connected to the first transmission component 50 at one end and to the lower housing 10 at the other end. Therefore, when driven by the drive unit 40, the lifting component 70 is driven by the first transmission component 50, causing it to move up and down relative to the lower housing 10.

[0042] like Figure 2 and Figure 3As shown, the second transmission component 60 is connected to the output shaft 410 of the driving unit 40 and is detachably connected to the tool 30 . Therefore, under the drive of the driving unit 40 , the tool 30 is driven to rotate through the second transmission component 60 .

[0043] The second transmission member 60 includes at least two gears, one of which is connected to the driving unit 40 , and one of the subsequent gears is connected to the cutter 30 . The second transmission member 60 transmits the rotation of the driving unit 40 to the cutter 30 .

[0044] Specifically, refer to Figures 2 to 13 , explaining the specific composition of the drive structure.

[0045] The drive unit 40 is mounted within the upper housing 20 and connected to the first transmission component 50 and the second transmission component 60, respectively. In the disclosed embodiment, the first and second transmission components 50 and 60 share a single output shaft 410 of the drive unit 40, meaning the drive unit 40 is a single-shaft motor. This reduces the cost of the ice cream maker 100. In this embodiment, the output shaft 410 is, for example, a gear shaft with teeth or a gear (not shown) at one end, and is positioned vertically and downwardly. The first and second transmission components 50 and 60 are connected to different portions of the output shaft 410. The drive unit 40 is capable of bidirectional drive, enabling the upper housing 20 to be raised and lowered and the cutter 30 to rotate clockwise and counterclockwise. Since the drive unit 40 is located within the upper housing 20, the circuit components associated with the drive unit 40 can be located within the upper housing 20. As a result, even during movement of the upper housing 20, these circuit components remain stationary relative to the upper housing 20, minimizing risks such as circuit damage and unstable connector insertion.

[0046] The first transmission member 50 includes a gearbox 51 meshed with the second portion 412 of the output shaft 410 of the driving unit 40 and an anti-slip member 53 for outputting the shifted power. The anti-slip member 53 is mounted on the gearbox 51 and connected to the lifting member 70.

[0047] As an example, the gearbox 51 may be a planetary gearbox. Figures 8 to 11As shown, the transmission 51 includes two planetary carriers 540, a plurality of planetary gears 550 rotatably connected between the two planetary carriers 540, and a first ring gear 560 and a second ring gear 570 meshingly connected to the outer surfaces of the plurality of planetary gears 550. The rotating shafts of the plurality of planetary gears 550 are connected to the two planetary carriers 540 at both ends, thereby rotatably connecting the plurality of planetary gears 550 between the two planetary carriers 540. Of the two planetary carriers 540, the one closer to the drive unit 40 allows the output shaft 410 to pass through and mesh with the plurality of planetary gears 550. The plurality of planetary gears 550 are arranged in a circle around the output shaft 410 and mesh with each other. The inner surface surrounded by the plurality of planetary gears 550 serves as the input end 51a of the transmission 51 and meshes with the output shaft 410 of the drive unit 40. The first ring gear 560 and the second ring gear 570 are ring gears with teeth on their inner circumferences. The first ring gear 560 is mounted on the upper housing 20. Its rotation is restricted, and when the output shaft 410 rotates, it drives the multiple planetary gears 550 to rotate. As the multiple planetary gears 550 rotate about their respective central axes (not shown), they also rotate relative to the first ring gear 560, which is fixed to the upper housing 20. In other words, the multiple planetary gears 550 orbit around the output shaft 410. This in turn drives the second ring gear 570 to rotate about the output shaft 410. The second ring gear 570 defines a receiving groove 510. The inner circumference of the second ring gear 570 has teeth. The multiple planetary gears 550 are received within the receiving groove 510, sandwiched between the two planetary gear carriers 540. The teeth on the outer circumferences of the multiple planetary gears 550 mesh with the teeth on the inner circumference of the second ring gear 570. An output portion 572 protrudes from the side of the second ring gear 570 away from the first ring gear 560. Furthermore, the output portion 572 extends toward a side (the lower side) away from the driving portion 40 and functions as the output end 51b of the first transmission component 50. A mounting groove 572a is formed in a recessed manner on a side of the output portion 572 away from the first ring gear 560. The mounting groove 572a is used to mount the anti-slip component 53. The mounting groove 572a and the anti-slip component 53 are connected, for example, by a mutually fitting sleeve. When the second ring gear 570 rotates, the anti-slip component 53 rotates synchronously with the second ring gear 570. The inner circumferential surface of the mounting groove 572a is formed with at least one first mating portion 572C having a concave and convex surface.

[0048] Furthermore, in the above embodiment, by changing the number of planetary gears 550, the number of teeth of each gear, the size, etc., different rotational speeds of the second ring gear 570 can be achieved. It is understood that the gearbox 51 of the present application is not limited to the example of the planetary gearbox described above, and any gearbox with coaxial input and output can be used. In addition, the gearbox 51 is not limited to the planetary gearbox comprising a first-stage planetary gear 550 and a first-stage second ring gear 570 as described above. It can be at least one of the planetary gears 550 and the second ring gear 570, and can also be provided with multiple stages, as long as the output shaft 410 is connected to the multiple planetary gears 550 of the first stage and the anti-slip component 53 is connected to the second ring gear 570 of the last stage.

[0049] like Figures 12 to 13 As shown, the anti-slip component 53 includes a sleeve portion 531 and at least one engaging component 59 movably mounted on the sleeve portion 531. The sleeve portion 531 is received in the mounting groove 572a and is connected to the first threaded transmission member 710 of the lifting component 70. The position and number of the engaging components 59 correspond to the first mating portion 572C.

[0050] The socket portion 531 extends toward a side (downward side) away from the output portion 572 to form the second output end 53 b of the first transmission member 50 .

[0051] The sleeve portion 531 has a connecting hole 53H extending vertically therethrough. The connecting hole 53H allows for the first threaded transmission member 710 of the lifting member 70 to be fixedly connected thereto, thereby securing the sleeve portion 531 of the anti-slip member 53 to the lifting member 70. The outer circumference of the sleeve portion 531 engages with the inner circumference of the mounting groove 572a of the output portion 572. The sleeve portion 531 includes at least one engaging groove 531C recessed toward the central axis of the anti-slip member 53. The position and number of the engaging grooves 531C correspond to the first mating portion 572C. A first positioning groove 531d is further recessed toward the central axis on the bottom surface of the engaging groove 531C. The outer circumference of the sleeve portion 531 includes two engaging walls 531b that cover both sides of the circumference of each engaging groove 531C when viewed from above, such that the two engaging walls 531b in each engaging groove 531C extend toward each other.

[0052] A retractable engaging member 59 is connected to the outer circumference of the sleeve portion 531. The engaging member 59 comprises an elastic member 591 (e.g., a spring) and an engaging member 592. Together with the sleeve portion 531, the engaging member 59 is engaged with the mounting groove 572a of the output portion 572. One end of the elastic member 591 is connected to the sleeve portion 531, and the other end is connected to the engaging member 592. Thus, the elastic member 591 is sandwiched between the sleeve portion 531 and the engaging member 592, allowing the engaging member 592 to be movably disposed relative to the sleeve portion 531. One end of the engaging member 592 is connected to the elastic member 591, while the other end protrudes from the sleeve portion 531 and abuts the inner circumference of the output portion 572. A second positioning groove 592d is formed on the surface of the engaging member 592 on the side connected to the elastic member 591, recessed in a direction away from the elastic member 591. The engaging member 592 has a second mating portion 592s on a surface facing away from the elastic member 591, which matches the convex and concave portions of the first mating portion 572C. One end of the elastic member 591 is positioned in the first positioning groove 531d, and the other end is positioned in the second positioning groove 592d, thereby sandwiching the elastic member 591 between the sleeve portion 531 and the engaging member 592. The engaging member 592 has two side wings 592b on either side of the anti-slip member 53 in the circumferential direction. By receiving the two side wings 592b in the engaging groove 531C, i.e., arranging the two side wings 592b closer to the central axis of the anti-slip member 53 than the two engaging walls 531b, and causing the two engaging walls 531b to abut against the two side wings 592b, the engaging member 592 is movably mounted in the sleeve portion 531. The elastic member 591 pushes the engaging member 592 toward the outside of the sleeve portion 531, causing a portion of the engaging member 592 to protrude from the sleeve portion 531 and abut against the corresponding first mating portion 572C of the engaging groove 531C. The engaging groove 531C has a sufficient depth to fully accommodate the engaging member 59 when it is compressed inwardly, i.e., the engaging member 59 does not protrude beyond the outer circumference of the sleeve portion 531. In addition, the forms of the engaging wall 531b and the side wings 592b are not limited to the examples described above, and may be arbitrarily configured as long as the engaging member 59 can be engaged with the engaging groove 531C.

[0053] By providing the first positioning groove 531d and the second positioning groove 592d, the positioning elastic member 591 can be easily installed to prevent the elastic member 591 from being displaced between the sleeve portion 531 and the engaging member 592. Furthermore, even when the engaging member 59 is subjected to uneven force, the elastic member 591 is unlikely to be displaced or loosened from between the sleeve portion 531 and the engaging member 592.

[0054] like Figures 2 to 5As shown, the lifting component 70 includes a first threaded transmission member 710 and a second threaded transmission member 720. One end of the first threaded transmission member 710 is fixedly connected to the sliding component 53 via a fastener (not shown). Partially or entirely, the outer peripheral surface exposed from the connecting hole 53H is threaded and threadedly engaged with the threaded hole 720H ​​of the second threaded transmission member 720. The second threaded transmission member 720 is fixedly mounted on the lower housing 10 and has a threaded hole (not shown) extending therethrough. The other end of the first threaded transmission member 710 extends toward one side (the lower side) of the lower housing 10 and passes through the threaded hole of the second threaded transmission member 720 disposed in the lower housing 10, becoming suspended in the air. Because the second threaded transmission member 720 is stationary, rotation of the first threaded transmission member 710 causes the anti-slip component 53 to move closer to or further from the second threaded transmission member 720 (i.e., to rise or fall). Furthermore, the first threaded transmission member 710 is a screw, and the second threaded transmission member 720 is a screw nut.

[0055] Furthermore, the central axes of the output shaft 410, planetary carrier 540, first ring gear 560, second ring gear 570, anti-slip member 53, first threaded transmission member 710, and second threaded transmission member 720 are coaxial. Thus, the drive unit 40 can synchronously drive the first transmission member 50 and the first threaded transmission member 710 to rise and fall, thereby synchronously extending and retracting the upper housing 20 relative to the lower housing.

[0056] Furthermore, the lifting component 70 may also include a first guide rod 730 and a second guide rod 740 that are interlocked. One end of the first guide rod 730 is fixedly connected to a non-movable portion of one of the upper housing 20, the gearbox 51, or the second transmission component 60, such as a portion integrally formed with the upper housing 20, the first ring gear 560, or the gear rack 600 of the second transmission component 60 described below. This restricts the rotation of the first guide rod 730 to synchronize with the movement of the anti-slip component 53. The other end of the first guide rod 730 extends toward the lower housing 10. One end of the second guide rod 740 is fixedly connected to the lower housing 10, thereby securing the second guide rod 740. The other end of the second guide rod 740 extends toward the upper housing 20. The walls of the first guide rod 730 and the second guide rod 740 overlap and are in sliding contact with each other. The first and second guide rods 730 and 740 are hollow straight rods. The hollow interiors of the first and second guide rods 730 and 740 allow the first threaded transmission member 710 to move without contacting the first threaded transmission member 710. The first guide rod 730 is raised and lowered synchronously with the upper housing 20 , the first transmission component 50 , and the first threaded transmission component 710 . During the raising and lowering process, the first threaded transmission component 710 is not easily displaced and is raised and lowered stably.

[0057] The first guide rod 730 and the second guide rod 740 can be cylindrical. Alternatively, the first guide rod 730 and the second guide rod 740 can be elliptical cylinders or polygonal cylinders with triangular, quadrilateral, or trapezoidal cross-sections, which can suppress radial or circumferential torsion during the raising and lowering of the first guide rod 730, thereby further stabilizing the raising and lowering of the first threaded transmission member 710. Furthermore, the first guide rod 730 and the second guide rod 740 can have contacting walls comprising ribs, protrusions or recesses, or grooves.

[0058] Figure 7 An example of a second transmission component 60 is shown. The second transmission component 60 includes multiple gears and a gear frame 600. The multiple gears, for example, are a first gear 610, a second gear 620, a third gear 630, a fourth gear 640, and a fifth gear 650, which are connected in sequence. The rotation axes of the multiple gears are supported on the gear frame 600, allowing the multiple gears to be rotatably connected to the gear frame 600. Furthermore, the first gear 610 is connected to the first portion 411 of the output shaft 410 of the drive unit 40, and the final fifth gear 650 is engaged with the transmission output component 660, thereby rotating synchronously with the fifth gear 650. A slot or hole 670 is formed through the transmission output component 660, which communicates with the exterior of the upper housing 20 and is adapted to engage with one end of the tool 30. This allows the tool 30 to rotate synchronously with the transmission output component 660 and the fifth gear 650. In this embodiment, the second transmission component 60 includes multiple gears connected in sequence, but this is not limited to this. Alternatively, a belt may be used to connect two gears. It can be understood that the second transmission component 60 can use an existing structure.

[0059] The cutter 30 comprises a cutter shaft 31 and a cutter head 32. One end of the cutter shaft 31 is connected to the slot or hole 670 in the upper housing 20, while the other end, the end away from the upper housing 20, is connected to the cutter head 32. During use, the cutter head 32 is placed within the container 1. The drive mechanism is capable of driving the upper housing 20 to move, thereby allowing the upper housing 20 to extend (or extend) relative to the lower housing 10, thereby driving the cutter head 32 to rise and fall relative to the lower housing 10 and the container 1.

[0060] During normal operation of the ice cream maker 100 of the present invention, the first transmission component 50 and the second transmission component 60 are driven simultaneously by the drive unit 40, meaning that the drive unit 40 can simultaneously perform the lifting and rotational motions of the cutter 30. At this time, because the engaging member 592 of the engaging member 59 abuts the corresponding first mating portion 572C of the mounting groove 572a, the anti-slip member 53 and the second ring gear 570 rotate synchronously, driving the lifting member 70 to move the upper housing 20 and the cutter 30 up and down relative to the lower housing 10, achieving both the upward and downward movement of the cutter 30 while rotating. Assuming the rotational force output from the second ring gear 570 is F1, the sliding resistance of the anti-slip member 53 relative to the second ring gear 570 is F2. During normal operation, F2 > F1, so the engaging member 59 remains in contact with the first mating portion 572C, and the anti-slip member 53 tightly abuts the second ring gear 570 of the transmission case 51, preventing displacement.

[0061] On the other hand, the ice cream machine 100 involved in the present invention can include a lifting limit switch, so that the cutter head 32 can properly reach the specified first and second positions, and the operation of the cutter head 32 does not exceed the range between the first and second positions. However, if the limit switch fails, the lifting component 70 moves to its maximum stroke and cannot continue to operate, but the drive unit 40 continues to operate, resulting in an increased load, which can easily damage the cutter 30, the drive unit 40, the circuit components that can control the drive unit 40, and the connections between the various components. Alternatively, if the cutter head 32 is blocked by a hard object such as hard ice while moving downward to shave ice, the load on the drive unit 40 can also increase, which can easily damage the cutter 30, the drive unit 40, the circuit components that can control the drive unit 40, and the connections between the various components. Therefore, in this application, a first transmission component 50 with an anti-slip component 53 is adopted as a protective measure. When the load of the driving part 40 increases, the rotational force F1 output from the second ring gear 570 becomes larger, so F2 is less than F1. At this time, the driving part 40 continues to drive the second ring gear 570 and the tool 40 to rotate. At this time, since the sliding resistance F2 of the anti-slip component 53 relative to the second ring gear 570 is less than the rotational force F1 output by the second ring gear 570, the first matching portion 572C of the second ring gear 570 is disengaged from the second matching portion 592s of the engaging component 59, so that the second ring gear 570 can no longer drive the anti-slip component 53 to rotate. Therefore, the second ring gear 570 rotates while the anti-slip component 53 remains stationary, so that the second ring gear 570 idles, and the lifting component 70 does not perform lifting and lowering movements.

[0062] Therefore, even if the limit switch fails, causing operational obstruction and increasing the load on the drive unit 40, the lifting member 70 will not continue to operate, preventing damage to the ice cream maker 100 and preventing user safety threats from forced operation of the lifting member 70. Furthermore, even if the load on the drive unit 40 increases, the drive unit 40 continues to drive the cutter head 32 to cut, allowing hard objects to be shredded or removed, thereby effectively eliminating the factors that increase the load on the drive unit 40. During the process of eliminating the factors that increase the load on the drive unit 40, i.e., during the process of decreasing F1 until F2 ≥ F1, the engaging member 59 that has slipped out of the first mating portion 572C re-slides into the adjacent first mating portion 572C under the elastic force of the elastic member 591. The anti-slip member 53 is once again engaged with the second ring gear 570 via the engaging member 59 and rotates synchronously with the second ring gear 570. The drive mechanism of the ice cream maker 100 then resumes normal operation, and the cutter head 30 can simultaneously rotate and lift. Therefore, even if the second ring gear 570 slips relative to the anti-slip member 53, one end of the first threaded transmission member 710 abuts the inner circumferential surface of the mounting groove 572a via the side surface of the anti-slip member 53 to which it is fixed, and the other end of the first threaded transmission member 710 is threadedly connected to the second threaded transmission member 720. Therefore, the anti-slip member 53 and the first threaded transmission member 710 remain in their original positions, and the anti-slip member 53 does not disengage downward from the mounting groove 572a. Once the second ring gear 570 rotates until the first mating portion 572C faces the engaging member 59, the anti-slip member 53 and the ice cream maker 100 can be used again. Therefore, according to the embodiments of the present application, an anti-slip member 53 and an ice cream maker 100 are provided that can prevent damage to the drive unit 40 of the ice cream maker 100 caused by excessive load. Furthermore, after the protective measures are implemented, the lifting function of the ice cream maker 100 can be continued without disassembling the machine for repair, thus re-implementing the protective measures.

[0063] In addition, since the first positioning groove 531d and the second positioning groove 592d are provided, even when the locking component 59 slides out of the first matching portion 572C and re-enters one of at least one first matching portion 572C, the elastic member 591 is not easily displaced or loosened between the socket portion 531 and the locking member 592.

[0064] also, Figure 12 、 Figure 13 The number of the engaging parts 59, the first matching parts 572C and the engaging grooves 531C shown is 3, but the present application is not limited thereto, and there can also be 1, 2, etc. Preferably, when there are more than 2, the more than 2 engaging parts 59 are evenly arranged along the axial direction of the sliding part 53. In this way, it is possible to suppress uneven force when the sliding part 53 rotates and suppress the shaking of the first threaded transmission part 710 of the lifting part 70.

[0065] It can be understood that in the example described above, the second transmission component 60 and the first transmission component 50 are both connected to the drive unit 40, but the present application is not limited to this. A sun gear can also be set on a gear of the second transmission component 60 (for example, the first gear 610), and the sun gear can be meshed and connected with the planetary gear 550 of the first transmission component 50.

[0066] It can be understood that a single-axis motor is used as the driving unit 40 in the example described above, but the present application is not limited to this. A dual-axis motor with two output shafts can be used as the driving unit, so that one output shaft is connected to the second transmission component 60 and the other output shaft is connected to the first transmission component 50.

[0067] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
