Description

Technical Field

[0001] This application relates to the field of ice cream making technology, and in particular to an ice cream making device. Background Technology

[0002] Ice cream is a frozen dessert made primarily from drinking water, dairy products, egg products, fruit products, soy products, sugar, and edible vegetable oils, with or without food additives and fortifiers. It is produced through processes such as mixing, homogenization, freezing, and hardening, resulting in an expanded volume. Ice cream has a delicate texture, rich aroma, and delicious taste. It contains a certain amount of milk fat and non-fat dry matter, possessing high nutritional value. Furthermore, it can regulate physiological functions, maintain osmotic pressure and pH balance, and provide a cooling effect, making it a popular frozen food among consumers.

[0003] Ice cream equipment is automated equipment specifically designed for producing frozen desserts—ice cream. Its core function is to achieve low-temperature solidification of raw materials and uniform churning and gas mixing, ultimately creating a smooth-textured ice cream. To ensure the cleanliness and hygiene of the ice cream, the equipment needs to be cleaned regularly. Currently, cleaning ice cream equipment typically requires disassembling each component and cleaning them individually, which is not only inconvenient but also time-consuming and labor-intensive. Summary of the Invention

[0004] The main purpose of this application is to propose an ice cream making device that aims to solve the problem that cleaning existing ice cream equipment usually requires disassembling the equipment and cleaning each part one by one, which is not only inconvenient but also time-consuming and labor-intensive.

The two transmission bevel gears are fixedly mounted on the first transmission shaft and the second transmission shaft, and both transmission bevel gears are used to mesh with the trigger bevel gear.

[0010] Optionally, multiple spherical rolling grooves are formed on the triggering inclined surface, and rolling balls are rolled in the rolling grooves.

[0011] Optionally, the first cleaning mechanism includes a first mounting cylinder and a first scraper.

[0012] Optionally, the second cleaning mechanism includes a second mounting cylinder and a second scraper.

The outer side of the second scraper is in contact with the inner wall of the raw material container, and the second scraper is fixedly connected to the second mounting cylinder.

[0013] Optionally, the stirring mechanism includes a central cylinder, which is fixedly mounted on the first drive shaft. Multiple inclined stirring blades are evenly arranged on the outer circumference of the central cylinder. The stirring blades are fixedly connected to the central cylinder by a mounting rod. The cross-section of the stirring blade is S-shaped, so that both the upper and lower sides of the stirring blade form S-shaped curved surfaces.

[0014] Optionally, the mixing mechanism includes a square frame-shaped mixing rack, which is fixedly connected to the second drive shaft.

[0015] This application's technical solution includes a shell containing a raw material container. A processing container is connected below the raw material container, and a refrigeration system is connected to the processing container. The processing container contains a stirring mechanism and a first cleaning mechanism, while the raw material container contains a mixing mechanism and a second cleaning mechanism. The stirring mechanism, the first cleaning mechanism, the mixing mechanism, and the second cleaning mechanism are all connected to a power mechanism via a transmission mechanism. The transmission mechanism includes a first transmission shaft and a second transmission shaft. The first transmission shaft is connected to the power mechanism and passes through the processing container, where it is rotatably and sealed. The stirring mechanism is fixedly mounted on the first transmission shaft. A first trigger transmission structure is provided between the first cleaning mechanism and the first transmission shaft. The second transmission shaft passes through the inner wall of the raw material container and is rotatably and sealed thereto.

A third trigger transmission structure is provided between the first and second transmission shafts. A trigger structure is provided between the first, second, and third trigger transmission structures. The refrigeration system, the power mechanism, and the trigger structures are all electrically connected to a control system.

[0016] During ice cream making, ice cream ingredients are placed into the ingredient container inside the shell. The control system activates the power mechanism, driving the first drive shaft to rotate. Simultaneously, the triggering structure is activated, triggering the third triggering transmission structure. The third triggering transmission structure transmits power to the second drive shaft, driving the mixing mechanism inside the ingredient container to rotate. This ensures uniform mixing of the ingredients and prevents issues such as cream and milk separation or undissolved sugar granules. The mixed ingredients flow from the bottom of the ingredient container into the processing container. The control system simultaneously activates the refrigeration system to provide the processing container with an environment conducive to ice cream solidification. At the same time, the first drive shaft drives the stirring mechanism inside the processing container to continuously rotate, breaking up the condensation layer on the inner wall of the processing container. This prevents localized over-solidification of the ingredients and ensures uniform cooling and solidification until the ingredients solidify into a smooth ice cream.

[0017] During equipment cleaning, the user injects cleaning water or food-grade cleaning solution into the raw material container and processing container, and switches to cleaning mode through the control system. The control system controls the trigger structure to activate, causing the first trigger transmission structure to activate and connect the first drive shaft to the first cleaning mechanism, the second trigger transmission structure to activate and connect the second drive shaft to the second cleaning mechanism, and the third trigger transmission structure to activate and connect the first drive shaft to the second drive shaft. The power mechanism drives the first drive shaft to rotate, which in turn drives the first cleaning mechanism (inside the processing container) through the first trigger transmission structure. At the same time, the third trigger transmission structure drives the second drive shaft to rotate, which in turn drives the second cleaning mechanism (inside the raw material container) through the second trigger transmission structure. The two cleaning mechanisms scrape the inner walls of their respective containers, working together with the cleaning water to complete a thorough cleaning.

[0018] The technical solution of this application integrates three major functions: raw material mixing, cooling and stirring, and dual container cleaning into one unit, so that the equipment does not need to be equipped with an additional mixer or cleaning tools; the control system realizes one-click production and one-click cleaning, eliminating the need to manually disassemble the containers, reducing the operation threshold, effectively improving the ease of use of the equipment, and making it suitable for home or small commercial scenarios.

[0028] Ice cream equipment is automated equipment specifically designed for producing frozen desserts—ice cream. Its core function is to achieve low-temperature solidification of raw materials and uniform mixing of air, ultimately forming a smooth-textured ice cream. To ensure the cleanliness and hygiene of the ice cream, the ice cream equipment needs to be cleaned regularly. Currently, cleaning ice cream equipment typically requires disassembling each component and cleaning them individually, which is not only inconvenient but also time-consuming and labor-intensive.

[0029] In view of this, this application proposes an ice cream making device.

[0030] In the embodiments of this application, reference is made to Figures 1 to 3 The ice cream making equipment described above includes: a shell 1, a raw material container 2 fixedly disposed near the top of the shell 1, a processing container 3 connected to the bottom of the raw material container 2 via a connecting pipe 202, the processing container 3 being fixedly connected to the inner wall of the shell 1, the processing container 3 being connected to a refrigeration system, a stirring mechanism 4 and a first cleaning mechanism 5 disposed inside the processing container 3, a mixing mechanism 6 and a second cleaning mechanism 7 disposed inside the raw material container 2, and the stirring mechanism 4, the first cleaning mechanism 5, the mixing mechanism 6 and the second cleaning mechanism 7 being connected to a power mechanism 830 via a transmission mechanism 8; The transmission mechanism 8 includes a first transmission shaft 810 and a second transmission shaft 820. The lower end of the first transmission shaft 810 is rotatably connected to the inner wall of the housing 1, and the upper end of the first transmission shaft 810 is rotatably connected to the second transmission shaft 820. The first transmission shaft 810 is connected to the power mechanism 830. The first transmission shaft 810 passes through the processing container 3 and is rotatably and sealed thereto. The stirring mechanism 4 is fixedly installed on the first transmission shaft 810. A first trigger transmission structure 840 is provided between the first cleaning mechanism 5 and the first transmission shaft 810. The second transmission shaft 820 passes through the inner wall of the raw material container 2 and is rotatably and sealed thereto. The mixing mechanism 6 is fixedly installed on the second transmission shaft 820. A second trigger transmission structure 850 is provided between the second cleaning mechanism 7 and the second transmission shaft 820. A third trigger transmission structure 860 is provided between the first transmission shaft 810 and the second transmission shaft 820. A trigger structure 870 is provided between the first trigger transmission structure 840, the second trigger transmission structure 850, and the third trigger transmission structure 860. The refrigeration system, power mechanism 830, and triggering structure 870 are all electrically connected to the control system.

[0031] During ice cream making, ice cream ingredients are placed into the ingredient container 2 inside the shell 1. The control system starts the power mechanism 830, which drives the first transmission shaft 810 to rotate. At the same time, the control trigger structure 870 is activated, which triggers the third trigger transmission structure 860. Through the third trigger transmission structure 860, the power is transmitted to the second transmission shaft 820, which drives the mixing mechanism 6 inside the ingredient container 2 to rotate, so as to achieve uniform mixing of the ingredients and avoid phenomena such as the separation of cream and milk in the ingredients and undissolved sugar granules. The mixed ingredients flow from the bottom of the ingredient container 2 into the processing container 3. The control system simultaneously starts the refrigeration system to provide the ice cream solidification environment for the processing container 3. At the same time, the first transmission shaft 810 drives the stirring mechanism 4 inside the processing container 3 to rotate continuously, breaking the condensation layer on the inner wall of the processing container 3, avoiding local over-solidification of the ingredients, and ensuring uniform cooling and solidification of the ingredients until the ingredients solidify into a smooth ice cream.

[0032] During equipment cleaning, the user injects cleaning water or food-grade cleaning solution into the raw material container 2 and the processing container 3, and switches to cleaning mode through the control system. The control system controls the trigger structure 870 to activate, causing the first trigger transmission structure 840 to trigger and connect the first transmission shaft 810 and the first cleaning mechanism 5, causing the second trigger transmission structure 850 to trigger and connect the second transmission shaft 820 and the second cleaning mechanism 7, and causing the third trigger transmission structure 860 to trigger and connect the first transmission shaft 810 and the second transmission shaft 820. The power mechanism 830 drives the first transmission shaft 810 to rotate, which drives the first cleaning mechanism 5 (inside the processing container 3) to operate through the first trigger transmission structure 840. At the same time, the third trigger transmission structure 86 drives the second transmission shaft 820 to rotate, which then drives the second cleaning mechanism 7 (inside the raw material container 2) to operate through the second trigger transmission structure 850. The two cleaning mechanisms scrape the inner walls of their respective containers, and together with the cleaning water, complete the thorough cleaning.

[0033] Specifically, the power mechanism 830 and the first drive shaft 810 form the core power chain. The third trigger transmission structure 860 enables the on-demand transmission of power to the second drive shaft 820. That is, power is transmitted when the ingredients need to be mixed during the ice cream making stage and when cleaning is required during the cleaning stage. At other times, the third trigger transmission structure 860 can be disconnected to reduce the load on the power mechanism 830. The trigger structure 870 controls the engagement / disengagement of the first trigger transmission structure 840 and the second trigger transmission structure 850. During the cleaning stage, the cleaning mechanism is activated to effectively clean the ice cream. During the making stage, only the stirring mechanism 4 and the mixing mechanism 6 are activated. At this time, both cleaning mechanisms are separated from the drive shaft to avoid idling and energy consumption, and to achieve seamless switching between making and cleaning.

[0034] Specifically, the top surface of the raw material container 2 is open, and a raw material cover 201 is provided at the opening; a first electric valve 203 is provided on the connecting pipe 202; the bottom surface of the processing container 3 is connected to a discharge pipe 301, the other end of which is connected to a discharge port provided on the shell 1, and a second electric valve 302 is provided on the discharge pipe 301. Both the first electric valve 203 and the second electric valve 302 are electrically connected to the control system; the refrigeration system includes a compressor, condenser, evaporator, etc. (existing technology); the control system includes a control panel, a control circuit board, temperature sensor, etc. (existing technology), wherein the control panel is located on the outside of the shell 1, and a control box 9 is also provided inside the shell 1. The control circuit board is located inside the control box 9, and the temperature sensor is located on the processing container 3; the power mechanism 830 includes a power box 831 located inside the shell 1. The power box 831 is connected to the first transmission shaft 810 through a gear set 832, and a drive motor, reducer, etc. (existing technology) are provided inside the power box 831.

[0035] In this embodiment, the trigger structure 870 includes a trigger block 871 disposed between the first trigger transmission structure 840 and the second trigger transmission structure 850, and a trigger bevel gear 874 disposed between the first transmission shaft 810 and the second transmission shaft 820. The trigger block 871 is mounted on the inner wall of the housing 1 via a horizontally arranged electric telescopic rod 875. The electric telescopic rod 875 is used to push the trigger block 871 to move towards the first trigger transmission structure 840 and the second trigger transmission structure 850. The electric telescopic rod 875 is electrically connected to the control system. The trigger block 871 is provided with trigger inclined surfaces 872 facing both the first trigger transmission structure 840 and the second trigger transmission structure 850. The trigger bevel gear 874 is fixedly mounted on the trigger block 871 via an elastic telescopic rod 876.

[0036] Specifically, during ice cream making, the control system controls the extension of the electric telescopic rod 875, pushing the trigger block 871 to move towards the third trigger transmission structure 860. The trigger bevel gear 874 carried by the trigger block 871 first triggers the third trigger transmission structure 860. At this time, the elastic telescopic rod 876 is slightly compressed to compensate for processing and assembly errors, ensuring that the third trigger transmission structure 860 is triggered. At this time, the trigger inclined surface 872 has not yet triggered the first trigger transmission structure 840 and the second trigger transmission structure 850, and the cleaning mechanism is not started. The power of the first transmission shaft 810 is transmitted to the second transmission shaft 820 through the trigger bevel gear 874 and the third trigger transmission structure 860, driving the mixing mechanism 6 to operate and complete the mixing of raw materials. During equipment cleaning, the control system further extends the electric telescopic rod 875, triggering the first trigger transmission structure 840 and the second trigger transmission structure 850 via the triggering inclined surface 872 of the trigger block 871. Simultaneously, the elastic telescopic rod 876 retracts, and the trigger bevel gear 874 maintains the trigger on the third trigger transmission structure 860. The power of the first transmission shaft 810 drives the second transmission shaft 820 to rotate, and also drives the two cleaning mechanisms through the first and second trigger structures 870, achieving synchronous cleaning of the raw material container 2 and the processing container 3. After cleaning, the electric telescopic rod 875 shortens, the trigger block 871 resets, and the transmission structures separate. By adjusting the extension of the electric telescopic rod 875 through the control system, it is possible to either "activate only the third trigger structure 870 to achieve ice cream making" or "activate all three trigger transmission structures simultaneously to achieve equipment cleaning," meeting the different stage requirements of ice cream making and equipment cleaning.

[0037] In this embodiment, the first trigger transmission structure 840 includes a first conical disk 841 with its conical surface facing the trigger block 871. The first conical disk 841 is splinedly connected to the first transmission shaft 810, meaning that the first conical disk 841 can slide along the axial direction of the first transmission shaft 810. At the same time, torque can also be transmitted between the first transmission shaft 810 and the first conical disk 841. A first transmission block 842 is provided on the surface of the first conical disk 841 corresponding to the first cleaning mechanism 5. A first transmission groove 843 is provided on the first cleaning mechanism 5 corresponding to the first transmission block 842. A first tension spring 844 is provided between the first conical disk 841 and the first transmission shaft 810 to prevent the first conical disk 841 from moving toward the first cleaning mechanism 5. The first end of the first tension spring 844 is fixedly connected to the first conical disk 841, and the second end of the first tension spring 844 is fixedly connected to the first transmission shaft 810. The electric telescopic rod 875 pushes the trigger block 871, and the trigger inclined surface 872 contacts the conical surface of the first conical disk 841, generating an axial thrust. The first conical disk 841 moves axially along the spline groove of the first transmission shaft 810. When the conical disk moves to the preset position, the first transmission block 842 on its surface is inserted into the first transmission slot 843 of the first cleaning mechanism 5, and the first transmission shaft 810 establishes a power connection with the first cleaning mechanism 5. At this time, the first transmission shaft 810 drives the conical disk and the cleaning mechanism to operate, thereby cleaning the treatment container 3. When the electric telescopic rod 875 shortens, the thrust of the trigger inclined surface 872 disappears, and the first tension spring 844 pulls the first conical disk 841 to move in the opposite direction along the spline groove. The transmission block disengages from the slot. At this time, the conical disk returns to its initial position, and the cleaning mechanism stops operating.

[0038] In this embodiment, the second trigger transmission structure 850 includes a second conical disk 851 with its conical surface facing the trigger block 871. The second conical disk 851 is splinedly connected to the second transmission shaft 820, meaning that the second conical disk 851 can slide along the axial direction of the second transmission shaft 820. At the same time, torque can also be transmitted between the second transmission shaft 820 and the second conical disk 851. A second transmission block 852 is provided on the surface of the second conical disk 851 corresponding to the second cleaning mechanism 7. A second transmission groove 853 is opened on the second cleaning mechanism 7 corresponding to the second transmission block 852. A second tension spring 854 is provided between the second conical disk 851 and the second transmission shaft 820 to prevent the second conical disk 851 from moving toward the second cleaning mechanism 7. The first end of the second tension spring 854 is fixedly connected to the second conical disk 851, and the second end of the second tension spring 854 is fixedly connected to the second transmission shaft 820. The electric telescopic rod 875 pushes the trigger block 871, and the trigger inclined surface 872 contacts the conical surface of the second conical disk 851, generating an axial thrust. The second conical disk 851 moves axially along the spline groove of the second transmission shaft 820. When the conical disk moves to the preset position, the second transmission block 852 on its surface is inserted into the second transmission slot 853 of the second cleaning mechanism 7, and the second transmission shaft 820 establishes a power connection with the second cleaning mechanism 7. At this time, the second transmission shaft 820 drives the conical disk and the cleaning mechanism to operate, thereby cleaning the treatment container 3. When the electric telescopic rod 875 shortens, the thrust of the trigger inclined surface 872 disappears, and the second tension spring 854 pulls the second conical disk 851 to move in the opposite direction along the spline groove. The transmission block disengages from the slot. At this time, the conical disk returns to its initial position, and the cleaning mechanism stops operating (same as the first trigger transmission structure 840).

[0039] In this embodiment, the third trigger transmission structure 860 includes two transmission bevel gears 861 symmetrically distributed around a trigger bevel gear 874. The two transmission bevel gears 861 are fixedly mounted on the first transmission shaft 810 and the second transmission shaft 820, and both transmission bevel gears 861 are used to mesh with the trigger bevel gear 874. When the electric telescopic rod 875 pushes the trigger block 871 to move, the trigger bevel gear 874 on the trigger block 871 first contacts the two transmission bevel gears 861. The elastic telescopic rod 876 is compressed to compensate for the meshing gap, ensuring that the trigger bevel gear 874 meshes tightly with the two transmission bevel gears 861. The power of the first transmission shaft 810 is transmitted to the second transmission shaft 820 through the transmission bevel gear 861, the trigger bevel gear 874, and the other transmission bevel gear 861, realizing dual-shaft linkage. When only the container 3 needs to work alone, the electric telescopic rod 875 retracts, the trigger block 871 drives the trigger bevel gear 874 to disengage from the two transmission bevel gears 861, the power transmission is interrupted, and the second transmission shaft 820 stops rotating.

[0040] In this embodiment, multiple spherical rolling grooves are formed on the triggering inclined surface 872, and rolling balls 873 are rolled within the rolling grooves. When the triggering inclined surface 872 of the trigger block 871 contacts the conical surfaces of the first conical disk 841 and the second conical disk 851, the rolling balls 873 in the rolling grooves of the inclined surface contact the conical surfaces, transforming traditional sliding friction into rolling friction. The rolling balls 873 rotate freely within the rolling grooves, forming point contact with the surface of the conical disks. Force is transmitted through rolling rather than sliding, significantly reducing friction loss and reducing wear on the triggering inclined surface 872 and the conical disks.

[0041] In this embodiment, the first cleaning mechanism 5 includes a first mounting cylinder 501 and a first scraper 502. The first mounting cylinder 501 extends through the inner wall of the processing container 3 to the first trigger transmission structure 840. A first transmission slot 843 is formed on the first mounting cylinder 501. The outer side of the first mounting cylinder 501 is sealed and rotatably connected to the processing container 3, and the inner side of the first mounting cylinder 501 is sealed and rotatably connected to the first transmission shaft 810. The outer side of the first scraper 502 is in contact with the inner wall of the processing container 3, and the first scraper 502 is fixedly connected to the first mounting cylinder 501. After the first trigger transmission structure 840 is triggered, the first mounting cylinder 501 receives the power from the first transmission shaft 810 through the first transmission slot 843 and rotates in a sealed manner around the first transmission shaft 810. The first mounting cylinder 501 drives the first scraper 502 to rotate synchronously. The outer side of the scraper is in close contact with the inner wall of the processing container 3, scraping off the ice cream residue on the inner wall. The scraped residue is washed away by cleaning water and discharged with wastewater.

[0042] In this embodiment, the second cleaning mechanism 7 includes a second mounting cylinder 701 and a second scraper 702. The second mounting cylinder 701 extends through the inner wall of the raw material container 2 to the second trigger transmission structure 850. A second transmission groove 853 is formed on the second mounting cylinder 701. The outer side of the second mounting cylinder 701 is rotatably and sealingly connected to the raw material container 2, and the inner side of the second mounting cylinder 701 is rotatably and sealingly connected to the second transmission shaft 820. The outer side of the second scraper 702 is in contact with the inner wall of the raw material container 2, and the second scraper 702 is fixedly connected to the second mounting cylinder 701. When activated, the second mounting cylinder 701 drives the second scraper 702 to rotate, and the outer side of the scraper is in contact with the inner wall of the raw material container 2, scraping off viscous residues such as syrup and cream, which are then discharged with the cleaning water.

[0043] In this embodiment, the stirring mechanism 4 includes a central cylinder 401, which is fixedly mounted on a first drive shaft 810. Multiple inclined stirring blades 402 are evenly arranged circumferentially on the outer side of the central cylinder 401. The stirring blades 402 are fixedly connected to the central cylinder 401 via mounting rods 403. The stirring blades 402 have an S-shaped cross-section, forming S-shaped curved surfaces on both the upper and lower sides. During the manufacturing process, the first drive shaft 810 drives the central cylinder 401 to rotate. The central cylinder 401 drives the multiple evenly distributed stirring blades 402 to rotate synchronously via the mounting rods 403. Because the overall cross-section of the stirring blades 402 is S-shaped, continuous S-shaped curved surfaces are naturally formed on both the upper and lower sides. When the stirring mechanism 4 rotates forward, the upper curved surface generates an upward lifting force on the raw material, forcing the raw material in the processing container 3 to circulate and tumble vertically. Simultaneously, the lateral inclination angle of the S-shaped cross-section causes the stirring blades 402 to generate circumferential shear force on the raw material during rotation. Combined with the even distribution of multiple blades, this shears and breaks up ice crystal particles in the raw material, preventing clumping.

[0044] Regarding the S-shaped cross-section design of the stirring blade: The S-shaped cross-section is a continuous and smooth curved structure. This structural design ensures that the surface angles of the upper and lower sides of the stirring blade 402 change continuously with the rotation position when rotating, forming a stable "spiral channel" that guides the raw material to flow along the blade surface and realizes interlayer exchange, solving the problem of temperature difference between the upper and lower layers caused by the "unidirectional push" of traditional straight-section blades. The S-shaped cross-section enables the stirring blade 402 to generate three forces simultaneously: vertical thrust (pushing the raw material upward), circumferential shear force (breaking ice crystals), and radial thrust (pushing the raw material to diffuse from the center to the edge). The superposition of these three force fields forms a complex flow field, ensuring that the raw material is cooled evenly during the cooling process and avoiding local overcooling that forms a hard core. The S-shaped cross-section is an integral structural design with high bending strength, which can withstand the greater resistance of ice cream raw materials at low temperatures (the viscosity of the raw material gradually increases during solidification), preventing blade deformation.

[0045] For details, please refer to Figure 4 When the power mechanism 830 drives the stirring mechanism 4 to rotate in the forward direction, that is, the stirring blade 402 moves in the first direction 404, the raw material moves upward along the S-shaped curved surface above the stirring blade 402. When the raw material moves to the end of the stirring blade 402, it will cover downward under the action of gravity. The design of multiple stirring blades 402 makes the raw material move up and down and flip repeatedly, realizing the layer exchange of raw materials and making the raw materials cool evenly. When the power mechanism 830 drives the stirring mechanism 4 to rotate in the reverse direction, that is, the stirring blade 402 moves in the second direction 405, the raw material will move downward along the S-shaped curved surface below the stirring blade 402. That is, the stirring blade 402 will squeeze the ice cream through the lower S-shaped curved surface, thereby pushing the ice cream out of the discharge pipe 301.

[0046] In this embodiment, the mixing mechanism 6 includes a square frame-shaped mixing rack 601, which is fixedly connected to a second drive shaft 820. During the ice cream making stage, the second drive shaft 820 drives the square frame-shaped mixing rack to rotate. As the square frame rotates, it cuts the raw materials, "chopping" and dispersing large sugar granules or unmelted cream. The "hollow area" formed by the frame structure allows the raw materials to pass through the frame, forming radial convection and preventing localized uneven mixing of raw materials.

[0047] This application's technical solution includes a shell containing a raw material container. A processing container is connected below the raw material container, and a refrigeration system is connected to the processing container. The processing container contains a stirring mechanism and a first cleaning mechanism, while the raw material container contains a mixing mechanism and a second cleaning mechanism. The stirring mechanism, the first cleaning mechanism, the mixing mechanism, and the second cleaning mechanism are all connected to a power mechanism via a transmission mechanism. The transmission mechanism includes a first transmission shaft and a second transmission shaft. The first transmission shaft is connected to the power mechanism and passes through the processing container, where it is rotatably and sealed. The stirring mechanism is fixedly mounted on the first transmission shaft. A first trigger transmission structure is provided between the first cleaning mechanism and the first transmission shaft. The second transmission shaft passes through the inner wall of the raw material container and is rotatably and sealed thereto. The mixing mechanism is fixedly mounted on the second transmission shaft. A second trigger transmission structure is provided between the second cleaning mechanism and the second transmission shaft. A third trigger transmission structure is provided between the first and second transmission shafts. A trigger structure is provided between the first, second, and third trigger transmission structures. The refrigeration system, the power mechanism, and the trigger structures are all electrically connected to a control system. By integrating three major functions—raw material mixing, cooling and stirring, and dual-container cleaning—the equipment eliminates the need for additional mixers or cleaning tools. The control system enables one-button production and cleaning, eliminating the need for manual container disassembly, thus lowering the operational threshold and effectively improving the ease of use of the equipment. It is suitable for home or small commercial scenarios.
