Description

Frozen food processing device Technical Field

[0001] The present invention relates to the technical field of frozen food processing, and in particular to a frozen food processing device. Background Art

[0002] Many frozen food processing devices on the market, such as ice cream machines, are made by rotating and mixing in a refrigerant container. Their production is cumbersome and time-consuming. Another processing method is the technical direction represented by NINJA and Swiss Pacojet ice grinders, such as the Chinese utility model patent with announcement number CN 216651197 U, which discloses a micro-fruit puree machine. The micro-fruit puree machine is an ice cream machine that lifts and lowers frozen ingredients and stirs and mixes them. Its lifting and stirring structure is cumbersome and expensive. Summary of the Invention

[0003] The purpose of the embodiments of the present invention is to provide a frozen food processing device to solve the problem that the frozen food processing device in the prior art is complex in structure and expensive.

[0004] The embodiment of the present invention adopts the following technical solution: a frozen food processing device, comprising:

[0005] The mixing cup has an open mouth and a rotating shaft at the bottom of the cup;

[0006] A freezing cup is a container with an open end for holding frozen food; the freezing cup can be inserted into the mixing cup through the cup mouth of the mixing cup through its open end, and the freezing cup can slide along the inner wall of the mixing cup so that the freezing cup can be placed in the mixing cup, or,

[0007] The freezing cup is detachably mounted in the mixing cup;

[0008] a stirring paddle assembly installed in the mixing cup, one end of the stirring paddle assembly being connected to the rotating shaft and being rotatable under the drive of the rotating shaft, for stirring the ingredients in the mixing cup;

[0009] A scraper plate is provided with a scraper, and the scraper plate is connected to the other end of the stirring paddle assembly or the rotating shaft, and can be rotated under the drive of the stirring paddle assembly or the rotating shaft, so that the scraper can scrape the frozen ingredients in the frozen cup layer by layer into the mixing cup.

[0010] By first freezing the ingredients in a freezer cup, then placing it on a mixing cup, and pressing down on the freezer cup or the stirring paddle assembly, a scraper on the scraper plate gradually scrapes the frozen ingredients from the freezer cup into the mixing cup. The stirring paddle assembly then stirs the ingredients in the mixing cup to make ice cream, etc. This frozen food processing device has a simple structure and is relatively affordable. It can be used with electric appliances such as juicers, meat grinders, and food processors, expanding the product's functionality and making it widely applicable.

[0011] In some embodiments, the freezing cup can slide downward along the inner wall of the mixing cup when subjected to a downward external force, so that the frozen food in the freezing cup remains in contact with the scraper.

[0012] The freezing cup can be pressed down manually so that the frozen food in the freezing cup can move toward the scraper in the mixing cup, thereby keeping the frozen food in contact with the scraper. In this way, the food processing device has a manual mode.

[0013] In some embodiments, the frozen food processing device further comprises an elastic compression member, one end of the elastic compression member is fixed in the mixing cup, and the other end of the elastic compression member is connected to the scraper plate;

[0014] When the freezing cup is detachably installed in the mixing cup, the frozen food in the freezing cup pushes the scraper plate downward and compresses the elastic compression member; when the elastic compression member is reset, it is used to apply a force to the scraper plate to move it upward, so that the scraper is pressed against the frozen food in the freezing cup, so that when the scraper plate rotates, the scraper can scrape the frozen food in the freezing cup layer by layer into the mixing cup.

[0015] By placing the frozen cup directly into the mixing cup to compress the elastic compression part, and then the elastic compression part resets and pushes the scraper plate to move upward, the scraper can scrape the frozen food in the frozen cup layer by layer into the mixing cup. This method makes the food processing device have an automatic mode, which is more labor-saving and convenient than the manual mode.

[0016] In some embodiments, the stirring paddle assembly includes at least two groups of stirring paddles, and at least two groups of stirring paddles each include a paddle shaft and a paddle blade, wherein the paddle blade is disposed on the paddle shaft and extends from the paddle shaft toward the inner wall of the mixing cup;

[0017] The paddle shafts of at least two groups of the stirring paddles are coaxially sleeved together and can be extended or retracted in sequence. The elastic compression member is arranged in the paddle shaft, wherein the paddle shaft located at the innermost or outermost side is connected to the rotating shaft. When the elastic compression member is reset, it can push the other paddle shafts to extend in sequence to push the scraper plate to move toward the frozen food in the frozen cup.

[0018] The elastic compression member drives the paddle shafts other than the paddle shaft connected to the rotating shaft to extend, so that the blades of the stirring paddle assembly are arranged in layers in the mixing cup, so as to stir the ingredients at different heights that fall into the mixing cup, thereby more fully stirring and mixing the scraped ingredients.

[0019] In some embodiments, the elastic compression member is a spring or an elastic rubber ring column. The spring and the elastic rubber ring column have simple structures and can be selected according to needs.

[0020] In some embodiments, the frozen food processing device further comprises a blade holder, which is provided with a material dropout port; the blade holder is hinged to the other end of the stirring paddle assembly and is coaxial with the stirring paddle assembly so as to remain stationary when the stirring paddle assembly rotates, thereby circumferentially limiting the scraper plate;

[0021] A scraper is provided on the plate surface of the scraper plate facing the blade holder, and the scraper is used to scrape the food on the blade holder to the drop opening, so that the food can fall into the mixing cup through the drop opening.

[0022] A blade holder coaxial with the stirring paddle assembly is hinged at the other end of the stirring paddle assembly. The blade holder serves to locate the rotation center of the scraper to prevent the scraper from swinging and scraping the surface of the frozen cup.

[0023] In some embodiments, the inner bottom wall and / or inner side wall of the freezing cup are provided with grooves and / or rib structures, the grooves and rib structures on the inner bottom wall of the freezing cup extend outward from the center of the inner bottom wall of the freezing cup, and the grooves and rib structures on the inner side wall of the freezing cup extend upward from the bottom of the inner side wall of the freezing cup; so as to limit the frozen food in the freezing cup from rotating with the scraper.

[0024] The groove and / or rib structure is used to prevent the frozen food in the freezing cup from being affected by the scraper's scraping of the frozen food when the scraper rotates synchronously with the scraper.

[0025] In some embodiments, the scraper plate is disc-shaped, and at least two scrapers are provided on the scraper plate. The at least two scrapers are spaced apart along the circumference of the scraper plate, and the blades of the scrapers are provided along the radial direction of the scraper plate.

[0026] At least two scrapers can scrape the frozen food at the same time, which can improve the scraping efficiency on the one hand, and improve the stability of the scraper plate when rotating on the other hand, and achieve more uniform scraping of the frozen food.

[0027] In some embodiments, the frozen food processing device also includes a main unit, which is provided with a driving device and a lower coupler, and an upper coupler is provided at the lower end of the rotating shaft. The driving device is connected to the lower coupler. When the mixing cup is placed on the main unit, the lower coupler is connected to the upper coupler to provide rotational power for the rotating shaft.

[0028] Through the cooperation of the upper coupler and the lower coupler, a fast and stable connection between the driving device and the rotating shaft can be achieved, so that the driving device can provide a stable driving force for the rotating shaft.

[0029] In some embodiments, the outer wall of the mixing cup is provided with a cup connecting rod, an elastic body, and a rod cavity. The cup connecting rod and the elastic body are both disposed in the rod cavity, and the elastic body is disposed at one end of the cup connecting rod so that when the freezing cup is detachably disposed in the mixing cup, the cup connecting rod can compress the elastic body, thereby allowing one end of the cup connecting rod to extend from the rod cavity at an end of the rod cavity close to the main machine; when the freezing cup is detached from the mixing cup, the elastic body stretches and resets, so that one end of the cup connecting rod is retracted into the rod cavity;

[0030] The main unit is provided with a safety interlock switch, which is connected in series to the circuit where the drive device is located. When the mixing cup is placed on the main unit, one end of the cup connecting rod triggers the safety interlock switch, so that the circuit where the drive device is located forms a closed loop.

[0031] When the mixing cup is placed on the main unit, the cup connecting rod on the mixing cup presses the safety interlock switch on the main unit, so that the circuit where the driving device is located is closed. Then, when the start switch on the main unit is turned on, the driving device can be started; when the mixing cup is not placed on the main unit, the driving device cannot be started even if the start switch on the main unit is turned on, thereby ensuring the safety of the frozen food processing device.

[0032] The beneficial effects of the embodiments of the present invention are:

[0033] By first freezing the ingredients in a freezer cup, then placing it on a mixing cup, and pressing down on the freezer cup or the stirring paddle assembly, a scraper on the scraper plate gradually scrapes the frozen ingredients from the freezer cup into the mixing cup. The stirring paddle assembly then stirs the ingredients in the mixing cup to make ice cream, etc. This frozen food processing device has a simple structure and is relatively affordable. It can be used with electric appliances such as juicers, meat grinders, and food processors, expanding the product's functionality and making it widely applicable. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0056] Specific embodiments of the present invention will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repetitive functions and structures are not described in detail to avoid obscuring the present invention with unnecessary or redundant detail. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but rather serve merely as a basis and representative basis for the above “Summary of the Invention” to teach those skilled in the art to variously employ the present invention in virtually any suitable detailed structure.

[0057] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," each of which may refer to one or more of the same or different embodiments according to the present invention.

[0058] To address the problems described in the background art, the present invention provides a frozen food processing device. The device comprises a mixing cup 1, a freezing cup 2, a stirring paddle assembly 3, and a scraper blade 4. The device can be used to process frozen meat to make minced meat, shaved ice, or ice cream, and is compatible with electric appliances such as juicers, meat grinders, and food processors. For ease of understanding, the present invention will be described using the frozen food processing device to make ice cream as an example.

[0059] As shown in Figure 1, the cup mouth of the mixing cup 1 is open, and a rotatable shaft 101 is provided in the bottom end of the cup. The shaft 101 extends upward from the bottom end of the mixing cup 1 and is used to connect with the stirring paddle assembly 3. When the shaft 101 rotates, it can drive the stirring paddle assembly 3 to rotate.

[0060] As shown in Figure 2, the freezing cup 2 is an open-ended container for holding frozen ingredients 8. For example, a prepared fruit ice cream recipe can be placed in the freezing cup 2 and then placed in a refrigerator for freezing to form the frozen ingredients 8 within the freezing cup 2. The freezing cup 2 can be inserted into the mixing cup 1 through its open end through the mouth of the mixing cup 1. Specifically, the freezing cup 2 containing the frozen ingredients 8 is placed upside down into the mixing cup 1, with the surface of the frozen ingredients 8 facing downward, so that the scraper 401 on the scraper plate 4 can contact and scrape the frozen ingredients 8 within the freezing cup 2.

[0061] The frozen food processing device can be set to manual mode or automatic mode as needed. As shown in Figure 3, for example, in manual mode, the freezing cup 2 can be turned upside down on the open end of the mixing cup 1, and then a force is applied downward to the freezing cup 2 to cause the freezing cup 2 to slide downward along the inner wall of the mixing cup 1, so that the freezing cup 2 can be placed inside the mixing cup 1. The surface of the frozen food 8 in the freezing cup 2 is continuously brought closer to the scraper plate 4 until the scraper 401 on the scraper plate 4 is attached to the surface of the frozen food 8 and the frozen food 8 is scraped layer by layer. The frozen food 8 scraped from the freezing cup 2 will fall into the mixing cup 1. In manual mode, the user can manually adjust the position of the freezing cup 2 in the mixing cup 1 as needed, thereby adjusting the amount of frozen food 8 scraped.

[0062] Alternatively, in automatic mode, as shown in FIG4 , the freezing cup 2 is completely placed in the mixing cup 1 and the freezing cup 2 is detachably mounted on the mixing cup 1 so that the surface of the frozen food 8 in the freezing cup 2 is in contact with the scraper 401 on the scraper plate 4. The scraper plate 4 is moved up and down by the extension and retraction of the stirring paddle assembly 3 to adjust the height of the scraper plate 4 in the mixing cup 1. At the same time, the scraper 401 always keeps in contact with the surface of the frozen food 8, thereby scraping the frozen food 8 as the scraper plate 4 continues to rise.

[0063] The stirring paddle assembly 3 is installed in the mixing cup 1 . One end of the stirring paddle assembly 3 is connected to the rotating shaft 101 and can rotate when driven by the rotating shaft 101 , so as to stir the ingredients in the mixing cup 1 .

[0064] As shown in FIG5 , the scraper plate 4 is provided with a scraper 401. The cutting edge of the scraper 401 faces the rim of the mixing cup 1. A drop hole is provided on the scraper plate 4 corresponding to the position of the scraper 401, allowing the scraped ingredients to fall through the drop hole into the mixing cup 1. The scraper plate 4 is connected to the other end of the stirring paddle assembly 3 or the rotating shaft 101. Driven by the stirring paddle assembly 3 or the rotating shaft 101, the scraper 401 can rotate to gradually scrape the frozen ingredients 8 from the frozen cup 2 into the mixing cup 1. Specifically, after the scraper 401 scrapes the frozen ingredients 8 from the frozen cup 2, the scraped frozen ingredients 8 fall into the mixing cup 1. Simultaneously, the stirring paddle assembly 3 continuously stirs and mixes the frozen ingredients 8 that have fallen into the mixing cup 1. During this continuous stirring process, the frozen ingredients 8 that have fallen into the mixing cup 1 are stirred and mixed into a slurry, such as slurry ice cream. After the mixing is completed, the freezing cup 2, the scraper 401 and the stirring paddle assembly 3 are rotated out and the mixing cup 1 contains edible ice cream.

[0065] In this embodiment of the present invention, ingredients are first frozen in a freezing cup 2, which is then attached to a mixing cup 1. Pressing the freezing cup 2 or the stirring paddle assembly 3 downward causes the scraper 401 on the scraper plate 4 to gradually scrape the frozen ingredients 8 from the freezing cup 2 into the mixing cup 1. The stirring paddle assembly 3 then stirs the ingredients in the mixing cup 1 to produce ice cream, etc. This frozen food processing device has a simple structure and is relatively affordable. It can be used with electric appliances such as juicers, meat grinders, and food processors, expanding the product's functionality and offering a wide range of applications.

[0066] In one embodiment of the present invention, again in conjunction with FIG3 , the frozen food processing device can adopt a manual mode, that is, when the freezing cup 2 is subjected to a downward external force, it can slide downward along the inner wall of the mixing cup 1 so that the frozen food 8 in the freezing cup 2 remains in contact with the scraper 401. The outer wall of the freezing cup 2 can be in contact with the inner wall of the mixing cup 1 and slide downward along the inner wall of the mixing cup 1 to avoid, as much as possible, the food in the mixing cup 1 from leaking from the gap between the inner wall of the mixing cup 1 and the outer wall of the freezing cup 2 during the mixing process, resulting in food waste and a poor user experience. The freezing cup 2 can be manually pressed downward so that the frozen food 8 in the freezing cup 2 can move toward the scraper 401 in the mixing cup 1, thereby allowing the frozen food 8 to remain in contact with the scraper 401. In this way, the food processing device has a manual mode.

[0067] In one embodiment of the present invention, again in conjunction with Figure 4, the frozen food processing device can also adopt an automatic mode, that is, the frozen food processing device also includes an elastic compression member 5, one end of the elastic compression member 5 is fixed in the mixing cup 1, and the other end of the elastic compression member 5 is connected to the scraper plate 4.

[0068] A fastener 102 for removably securing the frozen cup 2 can be provided at the rim of the mixing cup 1, while a screw lock 201 is provided on the outer wall of the bottom end of the frozen cup 2. After the frozen cup 2 is placed upside down in the mixing cup 1, the frozen cup 2 can be rotated so that the screw lock 201 engages with the fastener 102, thereby achieving a removable and fixed connection between the frozen cup 2 and the mixing cup 1. During the process of removably installing the frozen cup 2 in the mixing cup 1, the frozen food 8 in the frozen cup 2 continuously pushes downward against the scraper plate 4, causing the elastic compression member 5 to continuously compress until the frozen cup 2 is moved into place and is removably and fixedly connected to the mixing cup 1. The compressed elastic compression member 5 accumulates elastic potential energy and exerts a force on the scraper plate 4 to move it upward, so that the scraper 401 contacts the surface of the frozen food 8 in the frozen cup 2. As the scraper plate 4 rotates, the blade can scrape the frozen food 8 in the frozen cup 2 layer by layer into the mixing cup 1.

[0069] By placing the frozen cup 2 directly into the mixing cup 1 to compress the elastic compression member 5, and then the elastic compression member 5 is reset to push the scraper plate 4 to move upward, the scraper 401 can scrape the frozen food 8 in the frozen cup 2 layer by layer into the mixing cup 1. This method enables the food processing device to have an automatic mode, which is more labor-saving and convenient than the manual mode.

[0070] In one embodiment of the present invention, referring to Figures 3, 4, 5, 6, and 7, the stirring paddle assembly 3 may include a paddle shaft 301 and a paddle blade 302 disposed on the paddle shaft 301. The paddle blades 302 may be one or more. The two or more paddle blades 302 may be arranged at different heights along the paddle shaft 301, i.e., the paddle blades 302 may be arranged in layers on the paddle shaft 301. The paddle blades 302 and the paddle shaft 301 may be integrally formed, or one end of the paddle blade 302 may be connected to the paddle shaft 301. For example, the stirring paddle assembly 3 with the above structure may be used in manual mode. Of course, the stirring paddle assembly 3 with the above structure may also be used in automatic mode, where the scraper plate 4 rises and falls and rotates to scrape the frozen ingredients 8 in the frozen cup 2 in layers, while the stirring paddle assembly 3 does not rise or fall but only rotates to stir and mix the ingredients in the mixing cup 1. The lifting of the scraper plate 4 may be driven by the elastic compression member 5.

[0071] The stirring paddle assembly 3 may also include at least two groups of stirring paddles, each of which includes a paddle shaft 301 and a paddle blade 302. The paddle blade 302 is disposed on the paddle shaft 301 and extends from the paddle shaft 301 toward the inner wall of the mixing cup 1. The extension length of the paddle blade 302 is such that it does not affect the rotation of the stirring paddle assembly 3 and the lifting and lowering of the scraper plate 4. Specifically, when a large portion of the frozen food 8 in the frozen cup 2 has been scraped, the topmost paddle blade 302 will enter the frozen cup 2. At this time, the paddle blade 302 will not interfere with the inner wall of the frozen cup 2. For example, the stirring paddle assembly 3 may include three groups of stirring paddles, and the paddle shaft 301 of each group of stirring paddles may have a layer of paddle blades 302 disposed at the same height, or at least two layers of paddle blades 302 disposed at different heights.

[0072] In conjunction with Figures 8 and 9, the paddle shafts 301 of at least two groups of stirring paddles are coaxially nested together and can be extended or retracted in sequence. The outer wall of the inner paddle shaft 301 is provided with a guide protrusion or guide groove 304 arranged along the axial direction of the paddle shaft 301, and the inner wall of the outer paddle shaft 301 is provided with a guide groove 304 or a guide protrusion arranged along the axial direction of the paddle shaft 301. The guide protrusion cooperates with the guide groove 304 to enable the mutually nested stirring paddles to be smoothly extended or retracted without rotation. If it is necessary to fix each stirring paddle, this can be achieved by the mutual cooperation of the limit buckles 305 arranged on the inner wall of the paddle shaft 301 and the outer wall of the other paddle shaft 301 that cooperates with it. Specifically, referring to Figures 8 and 10, when the elastic compression member 5 is compressed, at least two groups of paddle shafts 301 are retracted; referring to Figure 9, when the elastic compression member 5 is extended and reset, at least two groups of paddle shafts 301 can be extended in sequence to increase the height difference between the paddle blades 302 on the paddle shafts 301, thereby stirring the ingredients at different heights in the mixing cup 1. This can better and more fully stir and mix the scraped ingredients, thereby improving the stirring and mixing effect.

[0073] The elastic compression member 5 can be disposed within the paddle shaft 301. Specifically, the paddle shaft 301 is cylindrical and has a space capable of accommodating the elastic compression member 5. The innermost or outermost paddle shaft 301 is connected to the rotating shaft 101. When the elastic compression member 5 is reset, it pushes the other paddle shafts 301 to extend sequentially, thereby pushing the scraper 4 toward the frozen food 8 within the frozen cup 2. There can be one or more elastic compression members 5. If there is only one elastic compression member 5, it can be coaxially arranged with the paddle shaft 301.

[0074] The elastic compression member 5 drives the paddle shafts 301 other than the paddle shaft 301 connected to the rotating shaft 101 to extend, so that the paddle blades 302 of the stirring paddle assembly 3 are arranged in layers in the mixing cup 1, so as to stir the ingredients at different heights that fall into the mixing cup 1, thereby more fully stirring and mixing the scraped ingredients.

[0075] In one embodiment of the present invention, the elastic compression member 5 is a spring or an elastic rubber ring column. The elastic rubber ring column can be made of, but is not limited to, food-grade rubber material to improve food safety. The spring and elastic rubber ring columns have simple structures and can be selected according to needs.

[0076] In one embodiment of the present invention, again referring to Figures 5, 6, and 7, the frozen food processing device further includes a blade holder 6, which is provided with a feeding opening 601. The blade holder 6 may be disc-shaped, and one or more feeding openings 601 may be provided as needed. The two or more feeding openings 601 may be arranged at intervals along the circumference of the disc-shaped blade holder 6. The blade holder 6 is hinged to the other end of the stirring paddle assembly 3 via a fixed plate 603 and is coaxial with the stirring paddle assembly 3. The two surfaces of the fixed plate 603 are respectively provided with hinged columns for hinge connection to keep the stirring paddle assembly 3 stationary when it rotates. The scraper plate 4 is provided with a positioning column 403, which cooperates with a positioning hole 602 provided in the center of the blade holder 6 to circumferentially limit the scraper plate 4 and prevent the scraper plate 4 from shaking during the rotation and lifting process and cutting the frozen cup 2.

[0077] Because there is a certain gap between the scraper plate 4 and the blade holder 6, in order to allow the food scraped from the frozen cup 2 to the blade holder 6 to fall into the mixing cup 1 through the drop opening 601, a scraper plate 402 is provided on the plate surface of the scraper plate 4 facing the blade holder 6. The scraper plate 402 scrapes the food on the blade holder 6 to the drop opening 601 while rotating with the scraper plate 4, so that the food can fall into the mixing cup 1 through the drop opening 601.

[0078] A blade holder 6 coaxial with the stirring paddle assembly 3 is hinged at the other end thereof, and the blade holder 6 serves to locate the rotation center of the scraper plate 4 to prevent the scraper 401 from swinging and scraping the surface of the frozen cup 2 .

[0079] In one embodiment of the present invention, referring to FIG2 , the inner bottom wall and / or inner side wall of the freezing cup 2 are provided with grooves and / or rib structures 202. The grooves and rib structures 202 on the inner bottom wall of the freezing cup 2 extend outward from the center of the inner bottom wall of the freezing cup 2, and the grooves and rib structures 202 on the inner side wall of the freezing cup 2 extend upward from the bottom of the inner side wall of the freezing cup 2, so as to restrict the frozen food 8 in the freezing cup 2 from rotating along with the scraper 401. That is, the frozen food 8 in the freezing cup 2 remains fixed relative to the freezing cup 2 in the radial direction of the freezing cup 2. The frozen food 8 can move up and down along the freezing cup 2, but cannot rotate within the freezing cup 2. This prevents the frozen food 8 from rotating within the freezing cup 2 and affecting the scraping of the frozen food 8 by the scraper 401.

[0080] In one embodiment of the present invention, the scraper plate 4 is disc-shaped and is equipped with at least two scrapers 401. The at least two scrapers 401 are spaced apart circumferentially along the scraper plate 4, with the blades of the scrapers 401 arranged radially along the scraper plate 4. The scrapers 401 can be evenly spaced along the circumference of the scraper plate 4, further improving the stability of the scraping of the frozen food 8 in the frozen cup 2. At least two scrapers 401 can simultaneously scrape the frozen food 8, which not only improves the scraping efficiency, but also enhances the stability of the scraper plate 4 during rotation, while achieving more uniform scraping of the frozen food 8.

[0081] In one embodiment of the present invention, with reference to Figures 11, 12, 13, and 14, the frozen food processing device further includes a main unit 7, which includes a drive unit 702. A lower coupler 703 is provided on the housing 701 of the main unit 7, and an upper coupler 103 is provided at the lower end of the rotating shaft 101. The drive unit 702 is connected to the lower coupler 703. When the mixing cup 1 is placed on the main unit 7, the lower coupler 703 is coupled to the upper coupler 103. When the drive unit 702 rotates, the upper and lower couplers 703 provide rotational power to the rotating shaft 101. The drive unit 702 can be driven by a motor, or manually by a cranking motion. The cooperation between the upper coupler 103 and the lower coupler 703 enables a quick and stable connection between the drive unit 702 and the rotating shaft 101, thereby providing a stable driving force for the rotating shaft 101 through the drive unit 702.

[0082] In one embodiment of the present invention, referring again to FIG. 14 , the outer wall of the mixing cup 1 is provided with a cup connecting rod 104, an elastic body 105, and a rod cavity 106. Both the cup connecting rod 104 and the elastic body 105 are disposed within the rod cavity 106, and an elastic body 105 (e.g., a spring) is disposed at one end of the cup connecting rod 104. This allows the cup connecting rod 104 to compress the elastic body 105 when the freezing cup 2 is detachably mounted on the mixing cup 1, thereby allowing one end (the lower end) of the cup connecting rod 104 to extend out of the rod cavity 106 from the end of the rod cavity 106 proximal to the main unit 7. When the freezing cup 2 is removed from the mixing cup 1, the elastic body 105 extends and returns to its original position, allowing one end of the cup connecting rod 104 to retract into the rod cavity 106.

[0083] The housing 701 of the main unit 7 is provided with a safety interlock switch 704, which can be located on the top surface of the housing 701. The safety interlock switch 704 is connected in series with the circuit of the drive device 702. When the mixing cup 1 is placed on the main unit 7, one end of the cup connecting rod 104 triggers the safety interlock switch 704, closing the circuit of the drive device 702. When the mixing cup 1 is placed on the main unit 7, the cup connecting rod 104 on the mixing cup 1 presses against the safety interlock switch 704 on the main unit 7, closing the circuit of the drive device 702. When the start switch 705 on the main unit 7 is turned on, the drive device 702 can be started. However, when the mixing cup 1 is not placed on the main unit 7, the drive device 702 cannot be started even if the start switch 705 is turned on, thus ensuring the safe use of the processing device.

[0084] The above describes in detail multiple embodiments of the present invention, but the present invention is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of the present invention, and these variations and modifications should fall within the scope of protection required by the present invention.
