Description

An ice cream machine Technical Field

[0001] This invention relates to the field of ice cream making technology, and specifically to an ice cream machine. Background Technology

[0002] Chinese invention patent CN220756436U discloses an ice cream machine, including a main unit with a drive device 1, a power shaft, a drive device 2, and a lifting platform. The drive device 2 drives the lifting platform to switch between a first position and a second position, and the power shaft is driven to rotate via the drive device 1. A cup assembly is detachably mounted on the lifting platform, and a blade assembly is located within the cup assembly, corresponding to the power shaft. When the drive device 2 drives the lifting platform from the first position to the second position, the power shaft extends into the cup assembly and engages with the blade assembly, and the drive device 1 drives the power shaft to rotate, thus cutting, mixing, and stirring the ingredients within the cup assembly. When the drive device 2 drives the lifting platform from the second position to the first position, the blade assembly separates from the power shaft. This prior art poses a safety hazard of pinching fingers during the lifting and lowering of the cup assembly.

[0003] Therefore, there is still room for improvement and development in existing technologies. Technical solutions

[0004] To address the problems in the prior art, the present invention provides an ice cream machine in which the mixing cup moves up and down with the lifting platform to make ice cream, while the outer cup remains on the machine casing. Furthermore, during the lifting and lowering process of the mixing cup, the mixing cup remains inside the outer cup, thus preventing the safety issue of fingers being pinched.

[0005] To achieve the above objectives, the technical solution applied in this invention is as follows:

[0006] An ice cream machine includes a housing with a first drive device and a second drive device inside; a stirring assembly driven to rotate by the first drive device; a lifting platform movably disposed below the output end of the first drive device, the lifting platform being driven by the second drive device to switch between a first position and a second position; and a cup assembly including a stirring cup and an outer cup, the stirring cup being slidably disposed inside the outer cup, the outer cup being detachably mounted on the housing, and at least one complementary first locking mechanism being provided between the outer cup and the housing; the stirring cup being detachably suspended on the lifting platform, and at least one complementary second locking mechanism being provided between the stirring cup and the lifting platform. This configuration, where the cup assembly is a double-cup structure, more specifically, includes a stirring cup and an outer cup. The stirring cup is slidably disposed inside the outer cup. When the cup assembly is assembled into the machine housing, the outer cup is locked to the machine housing by a first locking mechanism, and the stirring cup is locked to the lifting platform by a second locking mechanism. During operation, the stirring cup can rise and fall with the lifting platform to complete the ice cream making process, while the outer cup remains locked to the machine housing. The stirring cup is slidably disposed inside the outer cup, ensuring that the stirring cup remains inside the outer cup during the rising and falling process, thus preventing any hand-pinching safety issues.

[0007] According to the above scheme, the outer bottom or outer side of the outer cup is provided with at least one first locking block, and the housing is provided with a receiving cavity for accommodating the cup assembly. The receiving cavity is provided with at least one second locking block complementary to the first locking block. The first locking mechanism includes the first locking block and the second locking block, which are engaged to position the outer cup on the housing. With this configuration, during assembly, the user pushes the cup assembly into the receiving cavity of the housing. The first and second locking blocks are misaligned, requiring the outer cup to be rotated a certain angle to engage and lock them. During disassembly, the outer cup is first reversed a certain angle to disengage the first and second locking blocks, and then the outer cup, along with the entire cup assembly, is removed from the receiving cavity of the housing, making assembly and disassembly convenient.

[0008] According to the above scheme, the lifting platform is provided with an opening, and a fourth locking block is provided inside the opening. A third locking block, complementary to the fourth locking block, is provided on the mouth or wall of the stirring cup. The second locking mechanism includes the third and fourth locking blocks, which are interlocked to position the stirring cup on the lifting platform. At least one complementary anti-rotation mechanism is provided between the stirring cup and the outer cup. With this configuration, during assembly, the user pushes the cup assembly into the housing cavity, simultaneously pushing the stirring cup through the opening onto the lifting platform. The third and fourth locking blocks are in a misaligned state. After rotating the outer cup by a certain angle, the stirring cup will rotate with the outer cup due to the anti-rotation mechanism, causing the third and fourth locking blocks to engage and lock. During disassembly, the outer cup is first reversed by a certain angle to disengage the third and fourth locking blocks, and then the outer cup, along with the stirring cup, is removed from the lifting platform, making assembly and disassembly convenient.

[0009] In practical applications, the second locking block inside the housing cavity and the fourth locking block on the lifting platform are at the same angular position, and the first locking block on the outer cup and the third locking block on the stirring cup are at the same angular position. Under the action of the anti-rotation mechanism, rotating the outer cup causes the stirring cup to rotate, thereby realizing that when the housing locks the outer cup, the lifting platform locks the stirring cup at the same time; similarly, when the housing releases the outer cup, the lifting platform also releases the stirring cup.

[0010] It should be noted that the existing technology places the cup assembly on the surface of the lifting platform, and the driving device drives the lifting platform to move and switch between the first position and the second position. In contrast, the present invention locks the mouth or wall of the cup assembly with the lifting platform, and the second driving device drives the lifting platform to lift the cup assembly and switch between the first position and the second position.

[0011] According to the above scheme, a detection device is provided on the casing, and the detection device is correspondingly set with the cup assembly. This arrangement allows the detection device to check whether the cup assembly is properly installed, making it safer to use. More specifically, when the detection device detects that the cup assembly is properly installed, it is triggered, and the machine can operate normally; when the detection device detects that the cup assembly is not properly installed, it cannot be triggered, and the machine cannot operate normally.

[0012] According to the above scheme, a movable component is provided between the stirring cup and the outer cup, and the stirring cup is slidably disposed within the movable component. A first locking mechanism is provided between the stirring cup and the movable component. The movable component is slidably disposed within the outer cup, and a second locking mechanism and a sliding mechanism are provided between the movable component and the outer cup. This arrangement, by providing a movable component between the stirring cup and the outer cup, allows for extending the lifting stroke of the stirring cup. Under the action of the first and second locking mechanisms, the stirring cup will not detach from the outer cup during lifting. More specifically, the movable component is designed to solve the problem of the stirring cup rising too far, causing the bottom of the stirring cup to extend beyond the outer cup.

[0013] According to the above scheme, the first locking mechanism includes a first limiting block disposed on the lower outer wall of the mixing cup and a second limiting block disposed on the inner wall of the opening of the movable part, with the first limiting block and the second limiting block being locked in place. With this configuration, when the mixing cup rises to a certain position with the lifting platform, the first limiting block on the lower outer wall of the mixing cup will engage with the second limiting block on the inner wall of the opening of the movable part, causing the mixing cup to drive the movable part to rise, thereby extending the lifting stroke of the mixing cup.

[0014] According to the above scheme, the second locking mechanism includes a third limiting block disposed on the lower outer wall of the movable part and a fourth limiting block disposed on the inner wall of the outer cup opening, with the third limiting block and the fourth limiting block being locked in place. With this configuration, when the stirring cup raises the movable part to a certain position, the third limiting block on the lower outer wall of the movable part will engage with the fourth limiting block on the inner wall of the outer cup opening, thus ensuring that the stirring cup remains inside the outer cup during the lifting and lowering process.

[0015] According to the above scheme, the sliding mechanism includes a groove on the outer wall of the movable part and a sliding column on the inner wall of the outer cup, with the sliding column slidably disposed within the groove. This arrangement, with the cooperation of the sliding column and the groove, improves the lifting and lowering effect of the movable part. It should be noted that the sliding mechanism also serves to prevent rotation, ensuring that the movable part can only slide linearly relative to the outer cup, and cannot rotate relative to it.

[0016] According to the above scheme, the housing is equipped with a linear guide device corresponding to the lifting platform; the linear guide device includes a guide column, a guide sleeve, and a guide seat. The guide sleeve is fixedly connected to the lifting platform, the first end of the guide column is fixedly connected to the housing, and the second end of the guide column passes through the guide sleeve and is fixedly connected to the guide seat. The guide sleeve and the guide column are slidably connected. This arrangement makes the lifting platform more stable during linear lifting and lowering, preventing tilting and swaying.

[0017] According to the above scheme, the cup assembly includes a cup lid, and the cup lid and the stirring cup are detachably connected; the lifting platform is provided with an opening, and a fourth locking block is provided in the opening; the cup lid is provided with a third locking block that is complementary to the fourth locking block; the second locking mechanism includes a third locking block and a fourth locking block, and the third locking block and the fourth locking block are locked together so that the stirring cup and the cup lid are detachably connected, and the stirring cup can be hoisted on the lifting platform through the cup lid.

[0018] According to the above scheme, the stirring assembly includes a stirring shaft and a stirring blade. The first end of the stirring shaft is connected to the output end of the first driving device, and the second end of the stirring shaft is provided with a connector. The stirring blade is located inside the cup lid of the cup assembly, and the stirring blade is provided with a coupling part complementary to the connector. With this configuration, when the cup assembly moves close to the stirring shaft until the coupling part of the connector and the stirring blade are fully coupled, the stirring shaft, carrying the stirring blade, begins to rotate, and the cup assembly continues to move close to the stirring shaft to fully cut, mix, and stir the ingredients.

[0019] In practical applications, in the initial state, the stirring blade is positioned on the cup lid by the positioning mechanism. The cup lid has a perforation, and the coupling part of the stirring blade is located in the perforation. When the cup assembly moves close to the stirring shaft, the connector of the stirring shaft passes through the cup lid and is fully coupled with the coupling part of the stirring blade. The positioning mechanism releases the stirring blade, and the stirring shaft starts to rotate with the stirring blade. The cup assembly continues to move close to the stirring shaft to fully cut, mix and stir the ingredients.

[0020] According to the above scheme, the second driving device drives the lifting platform to switch between a first position and a second position via a transmission assembly. The transmission assembly includes multiple screws or worms, with the first end of each screw or worm connected to the output end of the second driving device and the second end threadedly connected to the lifting platform. When the cup assembly is assembled on the housing, the multiple screws or worms are evenly distributed around the center of the cup assembly. This configuration ensures that when the second driving device drives the multiple screws or worms to rotate, it drives the lifting platform to switch between the first and second positions. Furthermore, when the cup assembly is assembled on the housing, the even distribution of the screws or worms around the center of the cup assembly ensures the concentricity of the cup assembly and the stirring assembly during the lifting process, preventing the stirring blade from scraping the inner wall of the stirring cup.

[0021] According to the above design, a control panel is provided on the casing. This design makes operation convenient. Beneficial effects

[0022] Beneficial effects of this invention:

[0023] The present invention is designed such that, during operation, the mixing cup moves up and down with the lifting platform to complete the ice cream making, while the outer cup remains on the machine casing. Furthermore, during the lifting and lowering of the mixing cup, the mixing cup remains inside the outer cup, thus preventing any safety issues such as pinching hands. Attached Figure Description

[0034] The technical solution of the present invention will be described below with reference to the accompanying drawings and embodiments. Example

[0035] As shown in Figures 1 to 8, the ice cream machine of the present invention includes a housing 1, in which a first driving device 6 and a second driving device 8 are provided; a stirring assembly, which is driven to rotate by the first driving device 6; a lifting platform 4, which is movably disposed below the output end of the first driving device, and the lifting platform 4 is driven by the second driving device 8 to switch between a first position and a second position; and a cup assembly 5, which includes a stirring cup 17 and an outer cup 18. The stirring cup 17 is slidably disposed inside the outer cup 18, and the outer cup 18 is detachably installed on the housing 1. At least one complementary first locking mechanism is provided between the outer cup 18 and the housing 1. The stirring cup 17 is detachably suspended on the lifting platform 4, and at least one complementary second locking mechanism is provided between the stirring cup 17 and the lifting platform 4. This configuration, where the cup assembly 5 is a double-cup structure, more specifically, includes a stirring cup 17 and an outer cup 18. The stirring cup 17 is slidably disposed within the outer cup 18. When the cup assembly 5 is assembled into the housing 1, the outer cup 18 is locked to the housing 1 by a first locking mechanism, and the stirring cup 17 is locked to the lifting platform 4 by a second locking mechanism. During operation, the stirring cup 17 can rise and fall with the lifting platform 4 to complete ice cream making, while the outer cup 18 remains locked to the housing 1. The fact that the stirring cup 17 is slidably disposed within the outer cup 18 ensures that the stirring cup 17 remains within the outer cup 18 during its rise and fall, thus preventing hand pinching. Furthermore, the outer cup 18 also prevents the user's hands from directly contacting the frozen food inside the stirring cup 17 during operation, thus preventing frostbite.

[0036] In this embodiment, the outer cup 18 has at least one first locking block 26 on its outer bottom or outer side. The housing 1 has a receiving cavity 3 for accommodating the cup assembly 5. The receiving cavity 3 has at least one second locking block 27 that is complementary to the first locking block 26. The first locking mechanism includes the first locking block 26 and the second locking block 27. The first locking block 26 and the second locking block 27 are engaged, so that the outer cup 18 is positioned on the housing 1. With this configuration, during assembly, the user pushes the cup assembly 5 into the receiving cavity 3 of the housing 1. The first locking block 26 and the second locking block 27 are in a misaligned state. It is necessary to rotate the outer cup 18 by a certain angle to make the first locking block 26 and the second locking block 27 engage and lock. During disassembly, the outer cup 18 is first reversed by a certain angle to make the first locking block 26 and the second locking block 27 disengage. Then, the outer cup 18 is pulled out from the receiving cavity 3 of the housing 1, making assembly and disassembly convenient.

[0037] In this embodiment, the lifting platform 4 is provided with an opening, and a fourth locking block 29 is provided in the opening. The mouth or cup wall of the stirring cup 17 is provided with a third locking block 28 that is complementary to the fourth locking block 29. The second locking mechanism includes the third locking block 28 and the fourth locking block 29. The third locking block 28 and the fourth locking block 29 are locked together so that the stirring cup 17 is positioned and suspended on the lifting platform 4. At least one complementary anti-rotation mechanism is provided between the stirring cup 17 and the outer cup 18. With this configuration, during assembly, the user pushes the cup assembly 5 into the receiving cavity 3 of the housing 1, while simultaneously pushing the stirring cup 17 onto the lifting platform 4 through the opening. The third locking block 28 and the fourth locking block 29 are in a misaligned state. After rotating the outer cup 18 by a certain angle, the stirring cup 17 will rotate with the outer cup 18 due to the anti-rotation mechanism between them, causing the third locking block 28 and the fourth locking block 29 to lock together. During disassembly, the outer cup 18 is first reversed by a certain angle to disengage the third locking block 28 and the fourth locking block 29, and then the outer cup 18 is used to remove the stirring cup 17 from the lifting platform 4, making assembly and disassembly convenient.

[0038] In practical applications, the second locking block 27 in the accommodating cavity 3 of the housing 1 and the fourth locking block 29 on the lifting platform 4 are at the same angular position, and the first locking block 26 on the outer cup 18 and the third locking block 28 on the stirring cup 17 are at the same angular position. Under the action of the first anti-rotation mechanism, rotating the outer cup 18 causes the stirring cup 17 to rotate, thereby realizing that when the housing 1 locks the outer cup 18, the lifting platform 4 locks the stirring cup 17 at the same time; similarly, when the housing 1 releases the outer cup 18, the lifting platform 4 also releases the stirring cup 17.

[0039] It should be noted that in the prior art, the cup assembly 5 is placed on the surface of the lifting platform 4, and the driving device drives the lifting platform 4 to lift the cup assembly 5 and switch between the first position and the second position. In contrast, in this invention, the mouth or cup wall of the cup assembly 5 is locked to the lifting platform 4, and the second driving device 8 drives the lifting platform 4 to lift the cup assembly 5 and switch between the first position and the second position.

[0040] In this embodiment, a detection device 21 is provided on the housing 1, and the detection device 21 is correspondingly arranged with the cup assembly 5. This arrangement allows the detection device 21 to detect whether the cup assembly 5 is installed correctly, making it safer to use. More specifically, when the detection device 21 detects that the cup assembly 5 is installed correctly, it is triggered, and the machine can work normally. When the detection device 21 detects that the cup assembly 5 is not installed correctly, it cannot be triggered, and the machine cannot work normally.

[0041] In this embodiment, a movable member 20 is provided between the stirring cup 17 and the outer cup 18. The stirring cup 17 is slidably disposed within the movable member 20, and a first locking mechanism is provided between the stirring cup 17 and the movable member 20. The movable member 20 is slidably disposed within the outer cup 18, and a second locking mechanism and a sliding mechanism are provided between the movable member 20 and the outer cup 18. This arrangement, by providing the movable member 20 between the stirring cup 17 and the outer cup 18, allows the moving part 20 to extend the lifting stroke of the stirring cup 17. Under the action of the first and second locking mechanisms, the stirring cup 17 will not detach from the outer cup 18 during the lifting process. More specifically, the movable member 20 is to solve the problem that the stirring cup 17's lifting distance is too large, causing the bottom of the stirring cup 17 to extend beyond the outer cup 28.

[0042] In this embodiment, the first locking mechanism includes a first limiting block 14 disposed on the lower outer wall of the mixing cup 17 and a second limiting block 15 disposed on the inner wall of the opening of the movable member 20. The first limiting block 14 and the second limiting block 15 are locked together. With this configuration, when the mixing cup 17 rises to a certain position with the lifting platform 4, the first limiting block 14 on the lower outer wall of the mixing cup 17 will cooperate with the second limiting block 15 on the inner wall of the opening of the movable member 20 to lock together, and the mixing cup 17 will drive the movable member 20 to rise, thereby extending the lifting stroke of the mixing cup 17.

[0043] In this embodiment, the second locking mechanism includes a third limiting block 24 disposed on the lower outer wall of the movable member 20 and a fourth limiting block 25 disposed on the inner wall of the opening of the outer cup 18. The third limiting block 24 and the fourth limiting block 25 are locked together. With this configuration, when the stirring cup 17 drives the movable member 20 to rise to a certain position, the third limiting block 24 on the lower outer wall of the movable member 20 will cooperate with the fourth limiting block 25 on the inner wall of the opening of the outer cup 18 to lock together, thereby ensuring that the stirring cup 17 remains inside the outer cup 18 during the lifting and lowering process.

[0044] In this embodiment, the sliding mechanism includes a groove 22 on the outer wall of the movable member 20 and a sliding column 23 on the inner wall of the outer cup 18, with the sliding column 23 slidably disposed within the groove 22. This arrangement, with the cooperation of the sliding column 23 and the groove 22, improves the lifting and lowering effect of the movable member 20. It should be noted that the sliding mechanism also serves to prevent rotation, ensuring that the movable member 20 can only slide linearly relative to the outer cup 18, and cannot rotate relative to the outer cup 18.

[0045] In this embodiment, the housing 1 is equipped with a linear guide device corresponding to the lifting platform 4. The linear guide device includes a guide post 11, a guide sleeve 19, and a guide seat 13. The guide sleeve 19 is fixedly connected to the lifting platform 4, the first end of the guide post 11 is fixedly connected to the housing 1, and the second end of the guide post 11 passes through the guide sleeve 19 and is fixedly connected to the guide seat 13. The guide sleeve 19 and the guide post 11 are slidably connected. This arrangement makes the lifting platform 4 more stable during linear lifting and lowering, preventing tilting and swaying.

[0046] In this embodiment, the cup assembly 5 includes a cup lid 16, and the cup lid 16 and the stirring cup 17 are detachably connected.

[0047] In this embodiment, the stirring assembly includes a stirring shaft 7 and a stirring blade 10. The first end of the stirring shaft 7 is connected to the output end of the first driving device 6, and the second end of the stirring shaft 7 is provided with a connector 12. The stirring blade 10 is disposed inside the cup lid 16 of the cup assembly 5, and the stirring blade 10 is provided with a coupling part 30 that is complementary to the connector 12. With this configuration, when the cup assembly 5 moves close to the stirring shaft 7 until the connector 12 and the coupling part 30 of the stirring blade 10 are fully coupled, the stirring shaft 7, carrying the stirring blade 10, begins to rotate, and the cup assembly 5 continues to move close to the stirring shaft 7 to fully cut, mix, and stir the ingredients.

[0048] In practical applications, in the initial state, the stirring blade 10 is positioned on the cup lid 16 by the positioning mechanism. The cup lid 16 has a through hole, and the coupling part 30 of the stirring blade 10 is located in the through hole. When the cup assembly 5 moves close to the stirring shaft 7, the connector 12 of the stirring shaft 7 passes through the cup lid 16 and is fully coupled with the coupling part 30 of the stirring blade 10. The positioning mechanism releases the stirring blade 10, and the stirring shaft 7 starts to rotate with the stirring blade 10. The cup assembly 5 continues to move close to the stirring shaft 7 to fully cut, mix and stir the ingredients.

[0049] In this embodiment, the second driving device 8 drives the lifting platform 4 to switch between a first position and a second position via a transmission assembly. The transmission assembly includes multiple screws 9 or worms, with the first end of each screw 9 or worm connected to the output end of the second driving device 8 and the second end of each screw 9 or worm threadedly connected to the lifting platform 4. When the cup assembly 5 is assembled onto the housing 1, the multiple screws 9 or worms are evenly distributed around the center of the cup assembly 5. This configuration ensures that when the second driving device 8 drives the multiple screws 9 or worms to rotate, it drives the lifting platform 4 to switch between the first and second positions. Furthermore, when the cup assembly 5 is assembled onto the housing 1, the even distribution of the multiple screws 9 or worms around the center of the cup assembly 5 ensures the concentricity of the cup assembly 5 and the stirring assembly during the lifting process, preventing the stirring blade 10 from scraping the inner wall of the stirring cup 17.

[0050] In this embodiment, a control panel 2 is provided on the housing 1. This design makes it easy to operate.

[0051] The working principle of this invention is as follows: Ingredients are placed in the mixing cup 17, and the lid 16 is closed. The user holds the outer cup 18 and pushes the entire cup assembly 5 into the receiving cavity 3 of the housing 1. Under the action of the first and second locking mechanisms, the outer cup 18 is fixed to the housing 1, and the mixing cup 17 is fixed to the lifting platform 4. During operation, the second driving device 8 drives the lifting platform 4 and the mixing cup 17 to rise relative to the stirring shaft 7 until the stirring shaft 7 is coupled with the stirring blade 10. The first driving device 6 then drives the stirring shaft 7 to rotate the stirring blade 10 within the mixing cup 17, thus achieving cutting, mixing, and stirring of the ingredients. During the lifting and lowering process of the mixing cup 17, the mixing cup 17 remains within the outer cup 18, preventing any hand-pinching safety issues. After completion, the user holds the outer cup 18 and removes the entire cup assembly 5 from the receiving cavity 3 of the housing 1.

[0052] It should be noted that before making ice cream, all ingredients need to be put into the mixing cup 17 and crushed before the mixing cup 17 is put into the freezer to freeze into ice cubes. Therefore, the outer cup 18 is set on the outside of the mixing cup 17 to prevent the user's hands from directly contacting the frozen food in the mixing cup 17 and getting frostbite during operation. Example

[0053] In this embodiment, the lifting platform 4 is provided with an opening, and a fourth locking block 25 is provided in the opening. The cup lid 16 is provided with a third locking block 28 that is complementary to the fourth locking block 25. The second locking mechanism includes the third locking block 28 and the fourth locking block 29. The third locking block 28 and the fourth locking block 29 are locked together, so that the stirring cup 17 and the cup lid 16 can be detachably connected. The stirring cup 17 can be hoisted on the lifting platform 4 through the cup lid 16.

[0054] The difference between this second embodiment and the first embodiment is that in the first embodiment, the third locking block 28 is set on the mouth or wall of the stirring cup 17 and is suspended on the lifting platform 4 through the mouth or wall of the stirring cup 17. In the second embodiment, the third locking block 28 is set on the cup lid 16 and the stirring cup 17 is suspended on the lifting platform 4 through the cup lid 16. The rest of the structure and principle are the same as those in the first embodiment and will not be repeated.

[0055] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other modifications under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these modifications are within the scope of protection of the present invention.
