Description

Technical Field

[0001] This utility model belongs to the field of ice cream mixing technology, and particularly relates to a mixing blade, a mixing cup, and an ice cream machine. Background Technology

[0002] Existing blade assemblies typically employ a combination of two cutting blades and two mixing blades. The cutting blades are designed with a curved shape, lower at the front and higher at the back, while the mixing blades have a higher front and lower back design. The lower front and higher back design of the cutting blades, during the rotation and descent of the blade assembly driven by the drive shaft to agitate food, easily causes food to splatter along the inclined surface of the blades and stick to one end of the lid, resulting in significant food residue on the inner wall of the lid, affecting product hygiene and appearance. Summary of the Invention

[0003] The purpose of this invention is to provide a mixing blade, a mixing cup, and an ice cream maker, which effectively prevent food from splashing and sticking to the lid after being cut, thus improving hygiene and aesthetics.

[0004] To address the aforementioned problems, this utility model provides a stirring blade that can be fitted onto the lid of a stirring cup. The technical solution is as follows: It includes a shaft, stirring blades, and cutting edges. The stirring blades are mounted on the shaft, and the cutting edges are mounted on the surface of the stirring blades that is away from the cup lid.

[0005] Furthermore, this application also proposes that there be multiple cutting edges, which are spaced apart along the extension direction of the stirring blade.

[0006] Furthermore, this application also proposes that the stirring blade further includes a magnetic platform, which is fixedly installed relative to the shaft and can be attracted and fixed to the magnetic part provided on the cup lid.

[0007] Furthermore, this application also proposes that there are at least two stirring blades, and that the magnetic platform is fixed between two adjacent stirring blades.

[0008] Furthermore, this application also proposes that the stirring blade further includes a connector, a first mounting part and a first fitting, and an installation groove is provided on the end face of the shaft near the cup lid. A second mounting part is provided in the installation groove. The first mounting part can be connected to the second mounting part so that the connector is installed in the installation groove. The first fitting is used for assembly connection with the second fitting on the drive shaft of the ice cream machine.

[0009] Furthermore, this application also proposes that the first mounting member is a rib, which is disposed on the inner wall of the mounting groove and extends along the extension direction of the mounting groove; and the second mounting member is a groove, in which the rib can be inserted and is interference-fitted with the groove.

[0010] Furthermore, this application also proposes that the first assembly includes multiple locking strips, the connector has an assembly groove, the locking strips are located on the inner side wall of the assembly groove, and the multiple locking strips are spaced apart along the circumference of the assembly groove; the second assembly includes multiple locking blocks, and the locking blocks can be engaged between two adjacent locking strips.

[0011] This utility model provides a mixing cup, including a cup body, a cup lid, and the aforementioned mixing blade. The cup lid can cover the cup body, and the mixing blade can be assembled to the surface of the cup lid near the cup body. The cup lid has a clearance hole, through which the drive shaft of the ice cream machine can drive the mixing blade to rotate.

[0012] Furthermore, this application also proposes that the surface of the cup lid near the cup body is provided with a magnetic suction element, and the stirring blade includes a magnetic suction platform, which is fixedly installed relative to the shaft body and can be attracted and fixed with the magnetic suction element.

Detailed Implementation

[0018] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In existing technologies, ice cream machine blade assemblies typically employ a combination of curved cutting blades (lower at the front and higher at the back) and mixing blades. With this design, when the drive shaft rotates and moves the blades up and down, food easily splashes along the inclined surface of the blades onto the inner wall of the lid, resulting in food residue.

[0022] To address the aforementioned issues, researchers discovered that food splattering is closely related to the tilt angle and installation position of the cutting blade. Observation of the food's trajectory during cutting revealed that splattering primarily occurs during the downward movement of the blade assembly. Further analysis showed that confining the cutting area to below the stirring blade 120 effectively reduces upward food scattering. Based on this, an improved approach was proposed: fixing the cutting edge 130 to the lower surface of the stirring blade 120, ensuring that the cut food remains within the space below the blade.

[0023] Therefore, please refer to Figure 1 and Figure 4 This application proposes a structural design including a shaft 110, a stirring blade 120, and a cutting edge 130. The stirring blade 120 is mounted on the shaft 110, and the cutting edge 130 is disposed on the surface of the stirring blade 120 away from the lid. This structure ensures that food debris generated during the cutting operation is confined to the area below the stirring blade 120.

[0024] The shaft 110 is the central support component that carries the rotational movement of the stirring blade 120. It can be made of stainless steel hollow tubing, with an internal connecting structure to accommodate the drive shaft 300. The stirring blade 120 is the main component for mixing ingredients, and can be made of stamped fan-shaped stainless steel sheet with a wavy edge to enhance mixing. The cutting edge 130 is the sharp component for cutting and crushing ingredients. It can be made of carbide blades fixed to the lower surface of the stirring blade 120 with bolts, and the blade angle can be set to 30-45 degrees to optimize cutting efficiency.

[0025] Specifically, when the stirring blade 100 rotates with the shaft 110, the cutting edge 130 first contacts the food to cut and break it up. Since the cutting action occurs below the stirring blade 120, the cut food fragments are prevented from splashing upwards to the lid area by gravity and the blade's resistance. The stirring blade 120 continuously mixes and stirs the food below during rotation, creating a continuous processing flow. This structure, through spatial positioning, allows the cutting and stirring functions to be implemented in layers in the vertical direction.

[0026] Compared to existing technologies, the traditional cutting blade design, with its lower front and higher back, creates an upward-guiding slope, causing food to splatter along this slope. This solution changes the installation direction of the cutting blade 130, allowing the cutting force to work in tandem with gravity, effectively suppressing food from being thrown upwards. Simultaneously, the stirring blade 120 consistently covers the area above the food during the cutting process, forming a physical barrier.

[0027] Through the above technical solution, this application successfully confines the food generated during cutting to the space below the stirring blade 120, significantly reducing the amount of food adhering to the inner wall of the cup lid. The stirring blade 120 can contact the food during the lifting and lowering of the blade assembly, improving the uniformity of mixing. This structure can be adapted to the bidirectional rotary drive shaft 300 without changing the blade shaft connection method, enhancing equipment compatibility.

[0028] Please see Figure 1 and Figure 4 This application further proposes that there are multiple cutting edges 130, and the multiple cutting edges 130 are spaced apart along the extension direction of the stirring blade 120.

[0029] Among them, the cutting blade 130 refers to the sharp structure used to cut or crush food. Specifically, it can be made of stainless steel or high-hardness alloy material. It forms a cutting action by being fixed to the surface of the stirring blade 120. Its spacing can avoid local accumulation of food, which would increase the cutting resistance.

[0030] The extension direction of the stirring blade 120 refers to the linear or curved path of the blade radiating outward from the shaft 110. Specifically, it can be arranged in a straight line, spiral or wavy shape, and the interval arrangement makes the cutting edge 130 form multiple independent cutting areas in the blade length direction, thereby improving the cutting coverage.

[0031] Specifically, the cutting blades 130 are spaced apart along the surface of the stirring blade 120. When the stirring blade 120 rotates with the shaft 110, each cutting blade 130 creates a cutting action at a different position on the blade. Because the number of cutting blades 130 is increased and their distribution is uniform, the food is continuously cut under the blade, avoiding food splattering due to excessive load on a single cutting area. At the same time, the spaced arrangement makes the cut food fragments more uniform in size, reducing adhesion caused by insufficient cutting.

[0032] Compared to existing technologies, current mixing blades 100 typically employ a single cutting edge 130 or a non-uniformly distributed blade structure, resulting in low cutting efficiency and concentrated force on the food. This solution, through the spaced arrangement of multiple blades, distributes the cutting action to different positions of the blades, reducing the cutting pressure of a single blade, while simultaneously improving the pulverizing efficiency through the synergistic effect of multiple cutting points.

[0033] Through the above technical solution, this application can achieve uniform cutting of food under the stirring blade 120, reduce the problem of splashing caused by excessive local force, and improve cutting efficiency through the synergistic effect of multiple blades, thus avoiding food residue on the surface of the cup lid.

[0034] Please see Figures 1 to 4This application further proposes that the stirring blade 100 also includes a magnetic platform 140, which is fixedly installed relative to the shaft 110 and can be attracted and fixed to the magnetic part 220 provided on the cup lid.

[0035] Among them, the magnetic platform 140 refers to a planar structure with magnetic adsorption function, which can be implemented by using ferromagnetic metal materials or components with built-in permanent magnets, and forms a stable connection with the corresponding magnetic adsorption component 220 of the cup lid through magnetic force.

[0036] Fixed installation means that the magnetic platform 140 and the shaft 110 maintain an immovable relative position. This can be achieved through welding, riveting, or integral molding processes to ensure that the magnetic platform 140 does not shift during the rotation of the shaft 110.

[0037] The adsorption fixation refers to the magnetic platform 140 and the magnetic suction component 220 of the cup lid locking each other through magnetic attraction. Specifically, the magnetic suction component 220 can be made to adopt a permanent magnet or electromagnet structure, so that the stirring blade 100 and the cup lid form a detachable rigid connection.

[0038] Specifically, the magnetic platform 140 is fixed to the shaft 110. When the stirring blade 100 is assembled to the cup lid, the magnetic platform 140 contacts the magnetic suction element 220 preset on the inside of the cup lid and generates an adsorption force. In addition, the detachable connection between the magnetic platform 140 and the magnetic suction element 220 facilitates quick disassembly and assembly of the stirring blade 100 from the cup lid, making cleaning and maintenance easier.

[0039] This solution uses the magnetic platform 140 and the magnetic component 220 to fix the connection between the stirring blade 100 and the cup lid without being restricted by the rotation of the power shaft. At the same time, it simplifies the assembly structure and avoids the problem of thread wear or loosening caused by bidirectional rotation of the spiral structure.

[0040] Please see Figures 1 to 4 This application further proposes that the stirring blade 100 also includes a magnetic platform 140, which is fixedly installed relative to the shaft 110. The magnetic platform 140 can be attracted and fixed to the magnetic suction part 220 provided on the cup lid. There are at least two stirring blades 120, and the magnetic platform 140 is fixed between two adjacent stirring blades 120.

[0041] Among them, the stirring blade 120 refers to the component installed on the shaft 110 for cutting and stirring food. Specifically, it can be made of thin metal sheet or hard plastic, and the surface can be provided with serrations or cutting edges to enhance cutting efficiency.

[0042] The magnetic platform 140 refers to the structural component that fixes the stirring blade 100 to the cup lid through magnetic adsorption. Specifically, it can be made of permanent magnet or magnetizable metal material, and its shape can be circular, square or other regular geometric shape. It is fixed to the shaft 110 by welding, riveting or bolting.

[0043] The space between two adjacent stirring blades 120 refers to the gap area between two adjacent blades when multiple stirring blades 120 are arranged at intervals along the axis of the shaft 110. The magnetic platform 140 is fixed in this area, which does not affect the cutting function of the blades and can achieve magnetic positioning by utilizing the space.

[0044] Specifically, the magnetic platform 140 is fixed between two adjacent stirring blades 120, making the overall structure of the stirring blade 100 more compact and maximizing the contact area between the magnetic platform 140 and the magnetic suction part 220 of the cup lid, thereby improving the adsorption stability.

[0045] This solution optimizes space utilization and enhances the reliability of magnetic fixation by integrating the magnetic platform 140 between adjacent stirring blades 120.

[0046] Please see Figure 2 and Figure 3 This application further proposes that the stirring blade 100 also includes a connector 150, a first mounting part 151 and a first mounting part 152. The end face of the shaft 110 near the cup lid is provided with a mounting groove 111, and a second mounting part 112 is provided in the mounting groove 111. The first mounting part 151 can be connected with the second mounting part 112 so that the connector 150 is installed in the mounting groove 111. The first mounting part 152 is used to assemble and connect with the second mounting part 310 on the drive shaft 300 of the ice cream machine.

[0047] The connector 150 is an intermediate structure used to assemble the shaft 110 with the ice cream machine drive shaft 300. It can be implemented using a split-type snap-fit ​​structure, such as a detachable connection achieved through the cooperation of a snap-fit ​​strip and a snap-fit ​​block. The first mounting component 151 is the part of the connector 150 that mates with the second mounting component 112 within the mounting groove 111 of the shaft 110. It can be implemented using a raised rib or a recessed structure, such as an interference fit between the raised rib and the recessed groove to achieve axial positioning. The mounting groove 111 is a recessed space on the end face of the shaft 110 for accommodating the connector 150. It can be implemented using a circular or square groove structure, such as a groove formed by injection molding to match the connector 150. The second mounting component 112 is a component within the mounting groove 111 used to fix the connector 150. It can be implemented using a recessed or raised structure, such as an insertion fit between the recessed groove and the raised rib to achieve circumferential fixation. The first assembly 152 refers to the component in the connector 150 that is directly connected to the drive shaft 300. Specifically, it can be implemented using a clip or slot structure. For example, multiple circumferentially distributed clips can form an anti-disengagement latching connection with the drive shaft 300 clip.

[0048] Specifically, a second mounting member 112, such as a groove structure, is provided in the mounting groove 111 opened on the end face of the shaft 110. The first mounting member 151 of the connector 150 is inserted into the groove to fix the connector 150 to the shaft 110. The first mounting part 152 of the connector 150, such as a circumferentially distributed retaining strip, can form an interlocking engagement with the retaining block on the surface of the drive shaft 300. When the drive shaft 300 rotates forward or backward, the contact surfaces of the retaining strip and the retaining block can provide effective transmission resistance, preventing the connector 150 from disengaging from the drive shaft 300. During installation, the connector 150 is confined within the mounting groove 111 by the insertion and engagement of the first mounting member 151 and the second mounting member 112. At the same time, the engagement structure between the first mounting part 152 and the drive shaft 300 ensures the stability of power transmission.

[0049] Compared to existing technologies, the current tool assembly uses a helical structure with a unidirectional engagement with the drive shaft 300, which can easily lead to connection failure during reverse rotation. This solution, however, utilizes a circumferentially distributed design of locking strips and blocks, ensuring effective transmission of the drive shaft 300 through the locking surface regardless of whether it rotates clockwise or counterclockwise, preventing the tool assembly from detaching during bidirectional rotation. Furthermore, the connector 150 and the shaft 110 achieve quick assembly and disassembly via the mounting groove 111 and plug-in structure, making maintenance and replacement easier compared to the helical structure.

[0050] Through the above technical solution, this application can be adapted to the drive shaft 300 of an ice cream machine that rotates in both directions, ensuring that the stirring blade 100 maintains a stable connection with the drive shaft 300 during bidirectional rotation, preventing the blade assembly from falling into the cup due to reverse rotation, while simplifying the assembly process of the blade assembly and the drive shaft 300 and improving the reliability of the equipment.

[0051] Please see Figure 2 and Figure 3 This application further proposes that the first mounting member 151 is a rib, which is provided on the inner wall of the mounting groove 111 and extends along the extension direction of the mounting groove 111. The second mounting member 112 is a groove, in which the rib can be inserted and is interference-fitted with the groove.

[0052] The ribs refer to the strip-shaped protrusions on the inner wall of the mounting groove 111. Specifically, they can be strip-shaped protrusions extending axially along the mounting groove 111, forming a continuous guide structure by extending along the direction of extension. The grooves are groove structures that match the shape of the ribs. Specifically, they can be grooves formed on the surface of the connector 150, creating a clamping force between the ribs and the grooves through an interference fit. An interference fit means that the dimensions of the ribs and the grooves are designed to be mutually restrictive. Specifically, the width of the ribs can be slightly larger than the width of the grooves, generating radial clamping force through elastic deformation.

[0053] Specifically, the connector 150 is fixed to the shaft 110 through the cooperation of the first mounting member 151 and the second mounting member 112. When the rib is inserted into the groove, the frictional force generated by the interference fit can resist the relative rotation between the connector 150 and the shaft 110. Since the rib is continuously arranged along the extension direction of the mounting groove 111, the connector 150 can achieve self-positioning during installation through the guiding effect of the rib and the groove. At the same time, the clamping force generated by the interference fit can prevent the connector 150 from axial displacement or detachment when the drive shaft 300 rotates in both directions.

[0054] Compared with existing technologies, which use a spiral structure with drive shaft 300, the connector 150 is prone to loosening when rotating in the opposite direction. This solution uses the interference fit between the rib and the groove to form a stable circumferential limit, which can maintain the fixed state of connector 150 and shaft 110 without relying on the direction of rotation, thus solving the problem of connector 150 easily falling off under bidirectional rotation conditions.

[0055] Through the above technical solution, this application achieves a stable and reliable assembly relationship between the connector 150 and the shaft 110, avoids the connector 150 from coming loose when the ice cream machine drive shaft 300 rotates in both directions, and ensures that the stirring blade 100 can still maintain normal operation under bidirectional rotation conditions, thus significantly improving adaptability.

[0056] Please see Figure 2 and Figure 3 This application further proposes that the first assembly 152 of the connector 150 includes multiple locking strips, the connector 150 has an assembly groove 153, the locking strips are located on the inner side wall of the assembly groove 153, the multiple locking strips are arranged at intervals along the circumference of the assembly groove 153, and the drive shaft 300 of the ice cream machine is provided with multiple locking blocks, which can be locked between two adjacent locking strips.

[0057] Among them, the locking strip refers to the protruding structure set on the inner side wall of the assembly groove 153 of the connector 150. Specifically, it can be made of metal or high-strength plastic material, and is evenly distributed along the circumference. Adjacent locking strips form a locking gap, which is used to limit the displacement range of the drive shaft 300 locking block, thereby realizing torque transmission.

[0058] The "block" refers to the protruding structure on the outer surface of the drive shaft 300. Specifically, it can adopt a geometric shape that complements the "block" or "strip", such as a rectangular or trapezoidal cross section, and achieve bidirectional rotational power transmission by embedding it into the gap of the "block".

[0059] The circumferential spacing setting refers to the distribution of the clips in a ring array within the assembly slot 153. Specifically, they can be arranged at equal angular intervals, for example, one clip is set every 30 to 90 degrees to ensure that the clips can form an effective engagement in different rotation directions.

[0060] Specifically, when the drive shaft 300 is inserted into the assembly slot 153, its surface locking blocks embed into the gaps between adjacent locking strips, and the sidewalls of the locking strips contact the sides of the locking blocks to form a constraint. During the forward or reverse rotation of the drive shaft 300, the locking blocks push the locking strips, causing the connecting piece 150 to rotate synchronously. At the same time, the width of the gap between the locking strips is slightly larger than the thickness of the locking blocks, allowing for minor assembly errors. Because the locking strips are evenly distributed circumferentially, regardless of the direction of rotation of the drive shaft 300, at least two sets of locking strips are in contact with the locking blocks, preventing slippage during power transmission.

[0061] Compared to existing technologies, which employ a helical structure with a unidirectional drive shaft connection, reverse rotation can easily lead to connection failure. This solution, through a circumferential locking structure between the locking strip and the locking block, completely eliminates the restriction on the direction of rotation, achieving bidirectional power transmission without relying on helical lead, while also simplifying the machining of the connector 150. The planar contact between the locking strip and the locking block, compared to helical surface contact, reduces the risk of localized stress concentration and extends the service life of the components.

[0062] Through the above technical solution, this application solves the problem of the blade assembly easily detaching when the drive shaft 300 of the ice cream machine rotates in both directions. By forming a bidirectional power transmission interface through circumferentially distributed locking strips and blocks, the mixing blade 100 can be adapted to drive devices with different rotation directions. The locking structure maintains at least two sets of contact points during rotation, significantly improving connection stability and avoiding mixing failure caused by power interruption during food processing.

[0063] Please see Figure 4 and Figure 5This application further proposes a mixing cup, including a cup body, a cup lid, and a mixing blade 100. The cup lid can be placed on the cup body, and the mixing blade 100 can be assembled to the surface of the cup lid near the cup body. The cup lid has a clearance hole 210, and the drive shaft 300 of the ice cream machine can pass through the clearance hole 210 to drive the mixing blade 100 to rotate.

[0064] The clearance hole 210 refers to a through-hole structure formed on the cup lid, which can be implemented using a circular or rectangular hole. Its diameter or side length is slightly larger than the outer diameter of the drive shaft 300, ensuring that the drive shaft 300 can pass freely and transmit torque. The stirring blade 100 is assembled to the surface of the cup lid near the cup body by being attracted and fixed to the magnetic suction component 220 on the inner side of the cup lid via the magnetic suction platform 140. Specifically, a neodymium iron boron magnet can be embedded in the inner side of the cup lid, and the magnetic suction platform 140 is made of ferromagnetic metal material. The fitting structure between the cup body and the cup lid can be a threaded connection or a snap-fit ​​connection, for example, an external thread is provided at the mouth of the cup, and a matching internal thread is provided on the inner side of the cup lid.

[0065] Specifically, the mixing blade 100 is magnetically attached to the inner surface of the cup lid via the magnetic platform 140, and when the cup lid is closed, the mixing blade 100 is suspended inside the cup. After the drive shaft 300 of the ice cream machine passes through the clearance hole 210 and engages with the connector 150 of the mixing blade 100, the drive shaft 300 can rotate clockwise or counterclockwise to drive the mixing blade 100 to rotate stably. The cutting blade 130 continuously cuts the ingredients below the mixing blade 120, and the synchronous rotation of the mixing blade 120 achieves mixing. The ingredients, under centrifugal force, remain at the bottom of the cup, preventing splashing onto the inner wall of the cup lid.

[0066] Compared to existing technologies, current blade assemblies rely on a helical structure and a one-way engagement with the drive shaft 300, making them prone to detachment during forward rotation. This solution eliminates the helical structure by directly engaging with the drive shaft 300 through the clearance hole 210, allowing the stirring blade 100 to adapt to both forward and reverse rotation drive shafts 300. Simultaneously, the stirring blade 100 is fixed to the inside of the lid, preventing the blade assembly from detaching from the cup body during lifting and lowering. The synergistic effect of the cutting blade 130 and the stirring blade 120 ensures that food remains under the blades, reducing residue on the lid.

[0067] Through the above technical solution, this application solves the compatibility defects caused by the spiral structure of the blade assembly, achieving universal compatibility of the forward and reverse drive shaft 300. The cup lid clearance hole 210 simplifies the connection between the drive shaft 300 and the stirring blade 100, reducing assembly complexity. The magnetic fixing method enhances the operational stability of the stirring blade 100, and, combined with the downward placement of the cutting blade 130, effectively suppresses food splashing and adhesion to the cup lid.

[0068] Please see Figure 4This application further proposes that the surface of the cup lid near the cup body is provided with a magnetic suction element 220, and the stirring blade 100 includes a magnetic suction platform 140, which is fixedly installed relative to the shaft 110 and can be attracted and fixed with the magnetic suction element 220.

[0069] Among them, the magnetic platform 140 refers to the magnetic component fixed on the shaft 110 of the stirring blade 100. Specifically, it can be implemented using a permanent magnet or a magnetically conductive material, and is used to form an adsorption force with the magnetic component 220 of the cup lid.

[0070] Among them, the magnetic component 220 refers to the magnetic component embedded in the cup lid, which can be made of permanent magnet or ferromagnetic material. Through magnetic force and magnetic platform 140, the stirring blade 100 and the cup lid can be detachably fixed.

[0071] Specifically, the magnetic platform 140 is fixedly connected to the shaft 110 of the stirring blade 100. When the cup lid is closed with the cup body, the magnetic platform 140 directly contacts and attracts the magnetic component 220 on the inside of the cup lid.

[0072] In some specific embodiments, the magnetic platform 140 can be designed as a ring structure, circumferentially distributed around the shaft 110, and the magnetic components 220 can be correspondingly configured as a ring magnet array to increase the contact area and adsorption strength. Furthermore, the magnetic materials of the magnetic platform 140 and the magnetic components 220 can be neodymium iron boron magnets, and their surfaces can be covered with an anti-corrosion coating to improve durability.

[0073] Compared to existing technologies, where the stirring blade 100 uses a spiral structure to engage with the drive shaft 300, it is only compatible with unidirectional rotating drive shafts 300. This solution, however, uses a magnetic fixing method, achieving a stable connection regardless of the rotation direction, and is compatible with both forward and reverse rotating drive shafts 300. Furthermore, the magnetic fixing structure simplifies the installation process and avoids the risk of the spiral structure detaching due to wear.

[0074] Through the above technical solution, this application solves the problem that the stirring blade 100 is easy to fall off under the forward and reverse drive shaft 300. At the same time, the magnetic fixing method reduces the mechanical wear between the cup lid and the stirring blade 100, improves the reliability of the installation of the stirring blade 100, avoids food residue on the surface of the cup lid, and thus improves the stirring efficiency.

[0075] Please see Figure 5 This application further proposes an ice cream machine, including a drive shaft 300 and a mixing cup. The mixing cup includes a cup body, a cup lid, and a mixing blade 100. The cup lid can be placed on the cup body, and the mixing blade 100 can be mounted on the surface of the cup lid near the cup body. The cup lid has a clearance hole 210, and the drive shaft 300 can pass through the clearance hole 210 to drive the mixing blade 100 to rotate.

[0076] The drive shaft 300 is a shaft-shaped component that transmits rotational power. It can be made of stainless steel and has anti-slip textured surfaces to enhance friction with the stirrer blade 100 connector 150, directly driving the stirrer blade 100 to rotate. The clearance hole 210 is a through hole located at the center of the lid, with a diameter slightly larger than the drive shaft 300 diameter (e.g., 12 mm), allowing the drive shaft 300 to pass freely and connect with the stirrer blade 100 connector 150. The mixing cup is a container assembly consisting of a cup body, a lid, and the stirrer blade 100. The cup body can be made of food-grade plastic, and a magnetic 220 can be installed inside the lid for quick installation and positioning of the stirrer blade 100.

[0077] Specifically, after the drive shaft 300 passes through the clearance hole 210 of the cup lid, it forms a detachable connection with the connecting piece 150 of the stirring blade 100 through the engagement of a locking strip and a locking block. When the drive shaft 300 rotates forward or backward, the power is directly transmitted to the shaft 110 of the stirring blade 100 through the connecting piece 150, causing the stirring blade 120 and the cutting blade 130 to rotate synchronously. Since the stirring blade 100 is fixed to the cup lid using a magnetic platform 140, no axial displacement will occur during bidirectional rotation, avoiding the risk of detachment caused by the spiral structure in the prior art. The cutting blade 130 continuously cuts the food below the stirring blade 120, and the splashed debris is blocked by the stirring blade 120 and cannot contact the inner wall of the cup lid.

[0078] Compared to existing technologies, the blade shaft of current ice cream machines relies on a spiral structure to cooperate with the drive shaft 300, which only adapts to unidirectional rotation and poses a risk of detachment. This solution, however, uses a clearance hole 210 to directly connect with the drive shaft 300, allowing the mixing blade 100 to adapt to the bidirectional rotation drive shaft 300. Furthermore, the existing cutting blade's front-low, rear-high structure causes food to splatter along the inclined surface. This solution, by placing the cutting edge 130 below the mixing blade 120, uses the blade body to form a physical barrier, effectively reducing food residue.

[0079] Through the above technical solution, this application solves the compatibility problem of the bidirectional rotary drive shaft 300, ensuring that the stirring blade 100 can work stably in both forward and reverse rotation conditions. At the same time, by optimizing the blade layout, the amount of food splashing is significantly reduced, improving the reliability and cleanliness of ice cream making.
