[0009] In one embodiment, the driving component includes a rotary motor, a driven gear, and a second worm gear portion disposed on the output shaft of the rotary motor. The driven gear meshes with the transmission gear and the second worm gear portion on both sides, respectively; and / or The driving component includes a rotary motor and a driven gear set, wherein the rotary motor is driven to the transmission gear through the driven gear set.

[0010] In one embodiment, the housing includes an outer shell and an inner shell disposed inside the outer shell, the working cavity is formed in the inner shell, and the inner shell has a cable outlet groove communicating with the working cavity, the cable outlet groove extending in the vertical direction; The ice cream machine also includes a control circuit board located outside the inner shell. The control circuit board is electrically connected to the drive assembly via a wire assembly. The upper end of the wire assembly is fixed near the upper end of the wire outlet groove, and the lower end of the wire assembly passes through the mounting base and is fixed around the outside of the mounting base. As the mounting base rises, the wire assembly gradually transitions from an extended, relaxed state to an arc-shaped bent state. While undergoing bending deformation, the wire assembly can extend through the wire outlet groove to the outside of the inner shell.

[0011] In one embodiment, the cup assembly includes a cup holder and an ice cup, the cup holder having a locking groove in which the ice cup is locked.

[0012] In one embodiment, the bottom of the cup holder is provided with a plurality of locking protrusions, the ice cup is provided with a locking recess corresponding to each of the locking protrusions, and an anti-rotation ice groove is formed between any two of the locking recesses.

[0013] In one embodiment, the ice cream machine includes a stirring assembly, which includes a rotary drive assembly, a drive shaft, and a stirring blade. The stirring blade includes a blade shaft and a blade body connected together. The blade body is provided with multiple blades. The blade shaft is provided with a first magnetic element, and the end face of the blade shaft away from the blade body is provided with a connecting hole. The wall of the connecting hole is provided with a first connecting structure. The drive shaft extends in a vertical direction and is drivenly connected to the rotary drive assembly. The drive shaft includes a main rod and a second magnetic element provided at the lower end of the main rod. The lower end of the drive shaft is also provided with a second connecting structure. The first connecting structure and the second connecting structure are detachably connected, and the first magnetic element and the second magnetic element are magnetically connected to connect the blade shaft and the drive shaft.

[0014] In one embodiment, the cup device further includes a cup lid for covering the cup assembly.

A lifting assembly is provided between the upper lid and the lower lid to enable the upper lid to move in the vertical direction, and it has an installation position and a disassembly position. The cutting shaft is detachably installed on the upper lid. In the installation position, the upper lid is away from the lower lid, and the cutting shaft is assembled with the drive shaft. In the disassembly position, the upper lid is close to the lower lid, and the cutting shaft is detached from the drive shaft.

[0016] The technical solution of this utility model involves setting at least two lead screw and nut assemblies, with the lead screws of the assemblies located on both sides of the machine housing. The nut seats of the lead screw and nut assemblies are rotatably fitted onto the lead screws and rotatably connected to the mounting base. When the drive assembly rotates to drive the nut seats, the nut seats rotate relative to the mounting base and move along the extension direction of the lead screw, thereby causing the mounting base to move along the extension direction of the lead screw. As the lead screw extends vertically, the rotation of the nut seats, moving vertically along the lead screw, causes the mounting base to move vertically, which in turn causes the cup assembly to move vertically. Since the lead screws are located on both sides of the machine housing, the lead screw and nut assemblies can support the cup device from both sides, increasing the installation stability of the cup device. Because the nut seats move vertically along the extension direction of the lead screw, the vertical movement of the cup device is smoother, allowing the blades to cut the ingredients evenly, thus improving the texture of the prepared ice cream.

[0024] Home ice cream makers allow users to create and customize recipes according to their own preferences. They can also add nuts and other ingredients for even mixing, cutting, and stirring to make a variety of ice creams. The internal stirring and cutting blades of such home ice cream makers need to mix and cut the ingredients very finely to produce ice cream with a good texture.

[0025] Currently, when ice cream cups are moved upwards to allow the mixing and cutting blades to continuously cut the food, the cups tend to wobble, resulting in uneven cutting and a poor texture in the prepared ice cream.

[0026] To solve the above problems, this utility model proposes an ice cream machine 10.

[0027] Please see Figure 1 , Figure 4 and Figure 10 In one embodiment of this utility model, the ice cream machine 10 includes a housing 100, a cup device 200, and a lifting structure 300. The housing 100 has a working cavity 111. The cup device 200 is movably disposed within the working cavity 111. The cup device 200 includes a mounting base 210 and a cup assembly 220 detachably disposed on the mounting base 210. The lifting structure 300 includes a drive assembly 310 and at least two screw and nut assemblies 320. Each screw and nut assembly 320 includes a screw 321 and a nut seat 322 for rotatably sleeved on the screw 321. The two screws 321 extend in the vertical direction and are respectively disposed on both sides of the housing 100. The two nut seats 322 are rotatably connected to the mounting base 210. The drive assembly 310 is disposed on the mounting base 210 and is rotatably driven connected to the two nut seats 322.

[0028] The technical solution of this utility model involves setting at least two lead screw and nut assemblies 320, with the lead screw 321 of the lead screw and nut assembly 320 being disposed on both sides of the housing 100. The nut seat 322 of the lead screw and nut assembly 320 is rotatably sleeved on the lead screw 321 and rotatably connected to the mounting base 210. Thus, when the drive assembly 310 rotates to drive the nut seat 322, the nut seat 322 will rotate relative to the mounting base 210 and move along the extension direction of the lead screw 321, thereby driving the mounting base 210 to move along the extension direction of the lead screw 321. It can be understood that since the lead screw 321 extends in the vertical direction, the nut seat 322 rotates to move vertically along the lead screw 321, thereby driving the mounting base 210 to move vertically, and further driving the cup assembly 220 to move vertically, so that the blade can gradually cut the food. Since the lead screw 321 is located on both sides of the housing 100, that is, the lead screw nut assembly 320 is located on both sides of the housing 100, the lead screw nut assembly 320 can support the cup device 200 from both sides, which can increase the installation stability of the cup device 200. Since the nut seat 322 drives the mounting seat 210 to move up and down along the extension direction of the lead screw 321, the up and down movement of the cup device 200 is more stable, thereby making the blade cut the ingredients evenly and improving the taste of the prepared ice cream.

[0029] It should be noted that ingredients include, but are not limited to, nuts, ice cubes, fresh fruit, or frozen fruit, and the specific ingredients will depend on the user's actual use.

[0030] This design places the lead screw 321 of the lead screw and nut assembly 320 on both sides of the housing 100. That is, the lead screw and nut assembly 320 is placed on both sides of the mounting base 210. Compared with the design that only drives the mounting base 210 to move up and down on one side, the mounting base 210 is prone to tilting and deforming or even breaking in the direction away from the single-side drive structure due to the weight of the cup assembly 220 and the food inside the cup assembly 220 and the long-term influence of the downward force of the stirring blade 630. This design can better support the mounting base 210, thereby avoiding the breaking of the mounting base.

[0031] In one embodiment, the ice cream machine 10 further includes an upward sensor and a downward sensor disposed on the housing. The mounting base 210 has a starting position and a final position. The upward sensor corresponds to the starting position of the mounting base 210, and the downward sensor corresponds to the final position of the mounting base 210. It can be understood that since the cup assembly 220 is disposed on the mounting base 210, the starting position of the mounting base 210 also represents the starting position of the cup assembly 220, and the final position of the mounting base 210 also represents the final position of the cup assembly 220. Thus, the position of the cup assembly 220 is fed back to the machine controller through the downward sensor and the upward sensor. More specifically, if the machine controller controls the lifting structure to move downward, when the mounting base 210 corresponds to the upward sensor, that is, when the cup assembly 220 is in the initial position, the machine controller stops controlling the lifting structure 300 to continue to move downward. That is, the ice cream machine has finished cutting the ingredients. This can avoid the lifting structure from moving downward excessively, thereby avoiding damage to the lifting structure. When the ice cream machine is first turned on, the mounting base 210 aligns with the upward sensor, and the machine controller controls the lifting structure 300 to move upwards, thereby controlling the mixing blades 630 of the mixing assembly 600 to cut, mix, and stir the ingredients in the cup assembly 220. Then, when the mounting base 210 aligns with the downward sensor, the cup assembly 220 is in its final position, and the machine controller stops controlling the lifting structure 300 to continue moving upwards. This prevents the lifting structure from over-moving upwards, thus avoiding damage to the lifting structure.

[0032] The downlink and / or uplink sensors can be configured as Hall sensors or photoelectric sensors, and there is no limitation on this.

[0033] It should be noted that a stirring assembly 600 is also provided inside the housing 100. The stirring assembly 600 includes a rotary drive assembly 610, a drive shaft 620, and a stirring blade 630. The rotary drive assembly 610 is driven to the drive shaft 620 to drive the drive shaft 620 to rotate. The stirring blade 630 is mounted on the drive shaft 620, thereby enabling the rotary drive assembly 610 to drive the stirring blade 630 to rotate. The rotary drive assembly 610 drives the drive shaft 620 to rotate, thereby driving the stirring blade 630 to rotate. As the cup assembly 220 gradually moves upward under the drive of the lifting structure 300, the stirring blade 630 gradually cuts, mixes, and stirs the food inside the cup assembly 220, thereby enabling more thorough cutting, mixing, and stirring of the food at any position within the cup assembly 220.

[0034] Reference Figures 2 to 5 ,and Figures 10 to 14In this embodiment, two sets of lead screw and nut assemblies 320 are provided, with the two sets of lead screw and nut assemblies 320 respectively located on opposite sides of the housing 100. This embodiment is described using two sets of lead screw and nut assemblies 320 as an example. Of course, this embodiment is not limited to this; in other embodiments, four or five sets of lead screw and nut assemblies 320 may also be provided.

[0035] Optionally, in this embodiment, the driving assembly 310 includes a transmission rod 311 and a driving member 312. The driving member 312 drives the transmission rod 311 to rotate. The transmission rod 311 is provided with a transmission part corresponding to each of the nut seats 322. The transmission part is drivenly connected to the nut seats 322 to drive the nut seats 322 to rotate along the extension direction of the lead screw. It can be understood that when the driving member 312 drives the transmission rod 311 to rotate, the transmission part provided on the transmission rod 311 will also rotate, thereby driving the nut seats to rotate along the extension direction of the lead screw. This solution, through the setting of the transmission rod 311, realizes that one driving member 312 drives two nut seats 322 to rotate, so that the rotation accuracy of the two nut seats 322 is consistent, thereby making the vertical movement distance of the two nut seats 322 consistent, and thus keeping the two sides of the cup device 200 always horizontal. This can prevent the mounting base 210 from tilting after long-term use, and thus prevent the stirring blade 630 from failing to completely cut the food in the cup assembly 220. Of course, this solution is not limited to this. In other embodiments, a driving member can be provided for the lead screw nut assembly 320. The driving member is drivingly connected to the nut seat 322, and the two driving members drive the two nut seats 322 to rotate respectively.

[0036] In one embodiment, the transmission unit is configured as a first worm gear portion 313, and the nut seat 322 is provided with a worm wheel portion 322a corresponding to the first worm gear portion 313. The first worm gear portion 313 and the worm wheel portion 322a mesh with each other. It can be understood that when the driving member 312 drives the transmission rod 311 to rotate, the first worm gear portion 313 provided on the transmission rod 311 will also rotate. Since the first worm gear portion 313 and the worm wheel portion 322a mesh with each other, the rotation of the first worm gear portion 313 will drive the worm wheel portion 322a to rotate, thereby causing the nut seat 322 to move up and down along the lead screw 321. Such a driving assembly 310 drives smoothly and can improve the stability of the cup device 200 operation.

[0037] In the second embodiment, the transmission unit is configured as a bevel gear 315, and the nut seat 322 is provided with a bevel tooth portion 322b corresponding to the bevel gear 315. The bevel gear 315 and the bevel tooth portion 322b mesh with each other. It can be understood that when the driving member 312 drives the transmission rod 311 to rotate, the bevel gear 315 provided on the transmission rod 311 will also rotate. Since the bevel gear 315 and the bevel tooth portion 322b mesh with each other, the rotation of the bevel gear 315 will also drive the bevel tooth portion 322b of the nut seat 322 to rotate, thereby causing the nut seat 322 to move up and down along the lead screw 321. Such a driving assembly 310 drives smoothly and can improve the stability of the cup device 200 operation.

[0038] Furthermore, the transmission rod 311 is fitted with a transmission gear 314, and the driving member 312 is drivenly connected to the transmission gear 314. It can be understood that the transmission gear 314 allows the driving member 312 to be positioned around the periphery of the transmission rod 311, thus shortening the length of the driving assembly 310 and making its structure more compact. Moreover, the transmission gear 314 can achieve precise speed and torque conversion through its gear ratio, maintaining a constant transmission ratio unaffected by load changes. Of course, this solution is not limited to this. In other embodiments, the transmission gear 314 may be omitted, and the driving member 312 may be used directly to drive the transmission rod 311 to rotate, for example, but not limited to, using a rotary motor 312a to directly drive the transmission rod 311 to rotate.

[0039] Further, in this embodiment, the driving component 312 includes a rotary motor 312a, a driven gear 312b, and a second worm gear portion 312c disposed on the output shaft of the rotary motor 312a. The driven gear 312b meshes with the transmission gear 314 and the second worm gear portion 312c on both sides, respectively; this improves the driving accuracy of the driving component 312. In the second embodiment, the driving component includes a rotary motor 312a and a driven gear set 316. The rotary motor 312a is driven to the transmission gear 314 via the driven gear set 316. It can be understood that the rotary motor 312a drives the driven gear set 316 to operate, thereby causing the driven gear set 316 to drive the transmission gear 314 to rotate, which in turn drives the transmission rod 311 to rotate. This driving component has high operating accuracy, which can improve the operating accuracy of the cup device 200. Of course, this solution is not limited to this. In other embodiments, the drive unit 312 may only include a rotary motor 312a and a second worm gear 312c disposed on the output shaft of the rotary motor 312a, wherein the second worm gear 312c meshes with the transmission gear 314.

[0040] Furthermore, movable holes can be provided on both sides of the mounting base 210. The lifting structure 300 also includes a sleeve 142, which is located in the movable hole and is sleeved on the outer periphery of the nut seat 322. The bottom of the sleeve 142 is fixedly connected to the worm gear part 322a. The sleeve 142 is connected to the movable hole through a bearing. When the first worm part 313 rotates, it drives the worm gear part 322a of the nut seat 322 to rotate and rise. The sleeve 142 rotates in the movable hole and pushes the mounting base 210 to rise. When the worm gear part 322a rotates in the opposite direction and falls, the sleeve 142 drives the mounting base 210 to fall through the bearing, thus completing the connection and separation of the mounting base 210 and the stirring assembly 600.

[0041] Reference Figure 1 and Figure 8 The housing 100 is provided with a pick-up and put-out opening that communicates with the working chamber 111. The ice cream machine 10 also includes a door cover 130, which is movably disposed at the pick-up and put-out opening to open or close the working chamber 111.

[0042] In the technical solution of this utility model, the ice cream machine 10 includes a housing 100, and a working cavity 111 is formed inside the housing 100. A stirring assembly 600 and a cup assembly 200 are installed inside the working cavity 111. The stirring assembly 600 and the cup assembly 200 move relative to each other, allowing the stirring assembly 600 to move into the cup assembly on the cup assembly 200. The stirring assembly 600 grinds the ingredients inside the cup assembly by rotating. A loading / unloading opening is provided on one side of the working cavity 111, and a door cover 130 is provided on one side of the loading / unloading opening. One side of the door cover 130 is movably connected to the housing 100, allowing the working cavity to... The working chamber 111 is either open or closed. When the stirring component 600 in the working chamber 111 moves relative to the cup device 200, the door cover 130 is closed in advance, so that the inside of the working chamber 111 is closed. This isolates the sound of the internal stirring component 600 rotating and colliding with the food in the working chamber 111, reducing sound leakage. In addition, closing the door cover 130 can also reduce the probability of foreign objects such as external dust entering the cup assembly during grinding due to high-speed rotation, ensuring hygiene. Furthermore, closing the door cover 130 can also prevent accidental contact with the rotating stirring component 600, improving operational safety.

[0043] Specifically, the casing 100 can be square or round, without limitation. A support pad, L-shaped, can be provided at the bottom of the casing 100. The support pad can be made of silicone, which not only improves the friction between the casing 100 and supports such as a tabletop, preventing movement during food grinding, but also reduces shaking during operation. In this embodiment, the casing 100 has a square structure, including two side plates, a top plate, a bottom plate, a rear plate, and a front baffle. The two side plates are arranged opposite each other, and the top and bottom plates are arranged opposite each other from top to bottom. The two side plates, the rear plate, and the front baffle are respectively located on the four sides of the top plate, and the ends of the side plates and the rear plate furthest from the top plate are connected to the bottom plate. The two sides of the front baffle are connected to the two side plates respectively, and the bottom of the front baffle is spaced from the bottom plate to form a movable position. A working button can be installed on the front baffle. Pressing the button activates the internal stirring assembly 600, cup device 200, and other working components. The front baffle, side plate, bottom plate and rear plate together form a working cavity 111. The working cavity 111 is connected to the outside at the movable position. The door cover 130 is located at the movable position and is movably connected to the housing 100. In one embodiment, the door cover 130 and the housing 100 can be slidably connected to realize the docking of the door cover 130 and the housing 100, so that the working cavity 111 can be opened or closed. It can also be achieved by rotating connection through a hinge or other structure, which is not limited here.

[0044] In one embodiment, an observation port 131 may be provided on the door cover 130, and an observation window may be provided at the observation port 131. The operator can observe the internal working status through the observation window so that the machine can be stopped after the food is ground and the food can be taken out in time. The operator can also see and stop the machine in time if there is any abnormality in the internal working, so as to avoid other consequences.

[0045] In one embodiment, a sound-absorbing layer or a sealing strip may also be provided on the inner side of the door cover 130 to further improve the internal sound insulation effect.

[0046] The stirring assembly 600 and the cup device 200 are located inside the working chamber 111. When the stirring assembly 600 rotates and grinds the ingredients inside the cup assembly, it will collide with the ingredients and generate a certain amount of sound. Since the door cover 130 is closed at this time, the sound generated inside is reflected and attenuated multiple times by the inner wall of the housing 100 inside the working chamber 111, reducing the noise leakage to the outside and maintaining a relatively quiet working environment. Even if multiple ice cream machines 10 work at the same time, the sound generated by each ice cream machine 10 is effectively isolated, and the sound of each ice cream machine 10 is also prevented from superimposing. When the internal work is completed, the door cover 130 is opened and the ground ingredients in the cup assembly are taken out, which improves the internal hygiene and the operational safety of the operator.

[0047] In an embodiment of this utility model, the ice cream machine 10 further includes a rotating structure 140. The door cover 130 is rotatably connected to the machine housing 100 through the rotating structure 140. At the movable position, one side of the door cover 130 is provided with the rotating structure 140 between it and the machine housing 100. The rotating structure 140 allows the door cover 130 to rotate relative to the machine housing 100. The other side of the door cover 130 is close to or away from the machine housing 100, thereby closing or opening the working cavity 111. The rotating structure 140 can be disposed between the door cover 130 and one of the side plates, i.e., the central axis of rotation is in the vertical direction. The rotating structure 140 can also be disposed between the door cover 130 and the bottom plate or the front baffle, so that the door cover 130 can rotate up and down and flip over, i.e., the central axis of rotation is in the horizontal direction. No limitation is made here.

[0048] In one embodiment, the rotating structure 140 includes a rotating shaft 141 and a sleeve 142. The rotating shaft 141 is located on the side of the housing 100 where the take-up and take-down opening is provided, and the sleeve 142 is located on the door cover 130. The sleeve 142 is sleeved on the outer periphery of the rotating shaft 141 so that the door cover 130 rotates around the rotating shaft 141.

[0049] The rotating shaft 141 is fixed to the front baffle and the bottom plate of the housing 100 near the side plate, and extends vertically from the bottom of the front baffle to the bottom plate. The sleeve 142 can be configured as a through hole on one side of the door cover 130, extending from top to bottom. The rotating shaft 141 is disposed in the through hole, and the door cover 130 can rotate along the rotating shaft 141 through the through hole to close or open the working chamber 111. In one embodiment, the rotating shaft 141 can also be configured as two, respectively disposed on the front baffle and the bottom plate near the same side plate. One extends downward from the bottom of the front baffle, and the other extends upward from the top of the bottom plate. A sleeve 142 is provided at the top and bottom of the side of the door cover 130 near the side plate. It can be understood that a sleeve 142 is provided at the top and bottom of the door cover 130 and rotatably connected to the rotating shaft 141 to realize the rotation of the door cover 130. The rotating shaft 141 is segmented, which can reduce material costs and reduce the weight of the whole machine while ensuring rotational stability.

[0050] In an embodiment of this utility model, the ice cream machine 10 further includes a magnetic structure, which is disposed on the housing 100 and / or the door cover 130 so that the housing 100 and the door cover 130 are magnetically connected.

[0051] Specifically, such as Figure 2 and Figure 3As shown, the magnetic structure allows the door cover 130 to be stably connected to the housing 100 when closed, preventing it from being easily opened due to vibration or other external forces, which could affect internal operation and cause noise leakage. Specifically, if the door cover 130 is made of a magnetic metal, such as iron or copper, the magnetic structure is configured as a magnet and is set on the side of the housing 100 facing the door cover 130. When the door cover 130 is fastened to the housing 100, the magnet is magnetically attracted to the door cover 130. Similarly, if the side of the housing 100 facing the door cover 130 is made of a metal material that can be magnetically attracted, then the magnet is set on the door cover 130 and magnetically connected to the housing 100.

[0052] In one embodiment, the magnetic attraction structure may include a third magnetic element and a fourth magnetic element, which have opposite magnetic properties. The third magnetic element may be disposed on the door cover 130 or the housing 100, and the corresponding fourth magnetic element may be disposed on the housing 100 or the door cover 130. The third magnetic element and the fourth magnetic element are magnetically connected, so that the door cover 130 and the housing 100 are magnetically connected, thereby improving the stability of the magnetic connection.

[0053] In an embodiment of the present invention, the ice cream machine 10 further includes a locking structure for connecting the door cover 130 and the machine housing 100 when the door cover 130 and the machine housing 100 are closed.

[0054] Specifically, the locking structure is set between the door cover 130 and the housing 100. When the door cover 130 is rotated to the closed working chamber 111, the locking structure locks the door cover 130 and the housing 100 together, which can prevent the door cover 130 from being easily opened, affecting the safety of operation, and also ensure the noise reduction effect. After the internal processing is completed, the locking structure is opened and the door cover 130 is opened, so that one side of the door cover 130 is separated from the housing 100, thereby removing the cup assembly.

[0055] In an embodiment of this utility model, a limiting hole is provided on the side of the door cover 130, and the locking structure is configured as a push-pull electromagnet. The push-pull electromagnet is movably disposed on the side of the housing 100 where the take-up and take-down opening is provided. The push-pull electromagnet is used to extend to insert into the limiting hole after being energized, and to retract to disengage from the limiting hole after being de-energized.

[0056] Specifically, such as Figure 2 and Figure 3As shown, a push-pull electromagnet is installed on the side of the front baffle facing the movable position. The push-pull electromagnet includes a coil, a spring, and a pin. When the coil is energized, a magnetic field is generated, pushing the pin to extend towards the movable position. When the coil is de-energized, the magnetic field disappears, the spring retracts, and pulls the pin back, causing the pin to retract. A limit hole is provided on the upper part of the door cover 130. When the door cover 130 is closed, it is magnetically connected to the housing 100. However, if it is forcibly pulled, the door cover 130 can be separated from the housing 100. At this time, the coil is energized, causing the pin to extend and insert into the limit hole of the door cover 130, thereby preventing the door cover 130 from separating from the housing 100. At this time, even if more force is used, the door cover 130 cannot be opened, improving the safety of operation. When it is necessary to open the door cover 130, the coil is de-energized, causing the pin to retract, releasing the lock on the limit hole, and then the door cover 130 can be opened.

[0057] In other embodiments, the push-pull electromagnet can also be installed on the side of the base plate facing the movable position, and the limiting hole is set at the bottom of the door cover 130. There are no restrictions on this, as long as the position of the push-pull electromagnet corresponds to the position of the limiting hole.

[0058] In an embodiment of this utility model, the ice cream machine 10 further includes a detection structure. The detection structure is located on the side of the housing 100 facing the door cover 130. The detection structure is used to detect the closed state of the door cover 130 and the housing 100. Specifically, the detection structure can be located on the side of the bottom plate facing the movable position, or on the side of the front baffle facing the movable position, or on a side plate away from the rotating structure 140. When the door cover 130 is closed, the detection structure detects whether the door cover 130 is in contact with the housing 100 and seals the working cavity 111. If the door cover 130 is closed, the controller can control the locking structure to be energized to lock the door cover 130. When the detection structure detects that the door cover 130 is properly closed, the stirring assembly 600 and the cup device 200 inside the working cavity 111 can work, which can prevent operation when the door cover 130 is not properly closed, thus improving the safety of operation.

[0059] In one embodiment, the detection structure is configured as a Hall sensor, and an electromagnet is provided on the door cover 130. When the door cover 130 rotates and closes onto the housing 100 to seal the working cavity 111, the electromagnet approaches the Hall sensor and reaches the sensing surface of the Hall sensor. When the magnetic field strength exceeds the set threshold, the trigger inside the Hall sensor flips, thus determining that the door cover 130 has been closed.

[0060] In one embodiment, the detection structure is configured as a photoelectric sensor, which is mounted on the housing 100. When the door cover 130 is closed, it blocks the light and triggers the photoelectric switch. The photoelectric sensor then detects that the door cover 130 has been closed and can proceed to the next step.

[0061] Reference Figure 5 , Figure 9 and Figure 15 In this embodiment, a guide component 230 is also provided between the cup assembly 220 and the mounting base 210. The guide component 230 is used to limit the moving direction of the cup assembly 220 when it is picked up or placed.

[0062] In practical implementation, the housing 100 forms an installation space. The housing 100 can be a modular assembly structure or a one-piece structure, and the outline shape of the formed installation space can be any shape to meet actual needs. The cup assembly 220 and the mounting base 210 are guided by a guide assembly 230 to facilitate the placement and removal of the cup assembly 220. The guide assembly 230 may include at least two structural designs, and both the cup assembly 220 and the mounting base 210 are provided with corresponding structures that cooperate with each other to assist in the installation of the cup assembly 220 onto the mounting base 210 and its removal from the mounting base 210. Furthermore, in this embodiment, the cup assembly 220 is also provided with a handle, which makes it easier to pick up and place the cup assembly 220.

[0063] This utility model's technical solution involves placing both the stirring component 600 and the mounting base 210 within the installation space of the housing 100, with the mounting base 210 moving relative to the stirring component 600. The stirring component 600 rotates to grind the food inside the cup component 220. A guide component 230 is provided between the cup component 220 and the mounting base 210, which restricts the direction of movement of the cup component 220 during placement and removal, thus facilitating its easy handling. When placing the cup component 220 into the mounting base 210, installation is completed simply by pushing it along the guide component 230 to the corresponding position on the mounting base 210; the action is simple and quick. When removing the cup component 220 from the mounting base 210, it is simply pulled out in the direction away from the mounting base 210, making operation convenient and quick, thereby improving the ease of assembly and disassembly of the cup component 220 and enhancing the user experience. In addition, the guide component 230 can also serve as a limit. When the cup component 220 is located on the mounting base 210, the guide component 230 can limit the vertical displacement of the cup component 220, prevent the cup component 220 from shaking, and improve the stability of the cup component 220.

[0064] In one embodiment, the guide assembly 230 includes a first guide portion and a second guide portion. The first guide portion is disposed on the outer peripheral wall of the cup assembly 220, and the second guide portion is disposed on the mounting base 210. When the cup assembly 220 moves along the cup assembly 220, the first guide portion slides within the second guide portion.

[0065] Specifically, the first guide portion and the second guide portion are adapted to each other. Specifically, when the cup assembly 220 is installed on the mounting base 210 and when the cup assembly 220 leaves the mounting base 210, the first guide portion slides along the second guide portion. Furthermore, when the cup assembly 220 is located on the mounting base 210, the first guide portion is movably engaged in the second guide portion to limit the vertical displacement of the cup assembly 220 and the mounting base 210, so as to prevent the cup assembly 220 from shaking excessively when the stirring assembly 600 rotates and grinds, thus avoiding danger.

[0066] In one embodiment, the mounting base 210 includes a boss portion 211, the boss portion 211 having a placement groove 212 for placing a cup assembly 220 and a pick-up and put-out port communicating with the placement groove 212, the cup assembly 220 entering and exiting the placement groove 212 through the pick-up and put-out port, and a second guide portion being provided on the inner wall of the placement groove 212.

[0067] In the specific implementation process, a pick-and-place opening is provided on one side of the placement groove 212. The width of the pick-and-place opening is at least sufficient to ensure that the cup assembly 220 can pass through smoothly. Specifically, the cup assembly 220 is held and pushed into the placement groove 212 from the pick-and-place opening, so that the side wall of the placement groove 212 fits against the side wall of the cup assembly 220. The side wall of the placement groove 212 can also indicate that the cup assembly 220 is installed in place. The side wall of the cup assembly 220 is provided with a first guide portion, and the inner side wall of the placement groove 212 is provided with a second guide portion. Furthermore, to improve the stability of the cup assembly 220, the side wall of the placement groove 212 surrounds at least 3 / 4 of the side wall portion of the cup assembly 220. Both side walls of the placement groove 212 are provided with second guide portions, and correspondingly, the side wall of the cup assembly 220 is provided with corresponding first guide portions.

[0068] In one embodiment, the first guide portion is configured as a guide groove 231, which has a pick-and-place opening. At the pick-and-place opening, the two side walls of the guide groove 231 are inclined in a direction away from each other. The second guide portion is configured as a guide protrusion 232, which has an inlet end. The two side walls of the inlet end are inclined in a direction closer to each other. In another embodiment, the first guide portion is configured as a guide protrusion 232, and the second guide portion is configured as a guide groove 231 adapted to the guide protrusion 232. Both the guide groove 231 and the guide protrusion 232 extend along the travel distance of the cup assembly 220.

[0069] In the specific implementation process, a pick-and-place opening is provided at one end of the guide groove 231. The pick-and-place opening is funnel-shaped. Specifically, the two side walls of the guide groove 231 are inclined away from each other in the direction away from the guide groove 231 to increase the width of the pick-and-place opening, which facilitates fitting and sliding with the guide protrusion 232. The end of the guide protrusion 232 that first enters the guide groove 231 is the inlet end. The two side walls of the inlet end gradually approach each other in the direction near the end to reduce the width of the inlet end of the guide protrusion 232, so as to facilitate the guide protrusion 232 entering the guide groove 231.

[0070] Reference Figure 17 Furthermore, the bottom of the placement groove 212 is provided with a first protruding rib 231a and a second protruding rib 231b, and the bottom of the cup assembly 220 is provided with a first groove (not shown in the figure). That is, the bottom of the cup seat 221 is provided with a first groove, the first protruding rib 231a is slidably adapted to the first groove, and the second protruding rib 231b is used to contact the bottom of the cup assembly 220. In specific implementation, the extending direction of the first protruding rib 231a is consistent with the direction of the cup assembly 220 entering and exiting the placement groove 212, and when the cup assembly 220 enters and exits the placement groove 212, the cup assembly 220 slides along the first protruding rib 231a through the first groove, which plays a guiding role for the cup assembly 220. The second protruding rib 231b is provided at the bottom of the placement groove 212, and multiple second protruding ribs are provided. The second protruding rib 231b contacts the bottom of the cup assembly 220 to prevent the cup assembly 220 from rubbing against the bottom of the placement groove 212 and scratching the mounting base 210.

[0071] Reference Figure 8 , Figure 9 , Figure 15 and Figure 16 In one embodiment, the mounting base 210 includes a base portion, and the base portion is provided with a limiting component 240. The limiting component 240 has a limiting state and an avoidance state. In the limiting state, the limiting component 240 is at least partially protruding from the base portion and located on the displacement stroke of the cup assembly 220 away from the mounting base 210 to limit the movement of the cup assembly 220. In the avoidance state, the limiting component 240 is away from the base portion.

[0072] In this embodiment, the limiting component 240 is used to limit the displacement of the cup assembly 220 located in the placement groove 212, thereby improving the stability of the cup assembly 220. In the limiting state, the limiting component 240 abuts against the side wall of the cup assembly 220 opposite to the pick-up / drop-off opening, preventing the cup assembly 220 from leaving the placement groove 212, thus achieving a limiting function. In the avoidance state, the limiting component 240 moves away from the side wall of the cup assembly 220 and retracts into the interior of the base portion, away from the base portion, to avoid affecting the cup assembly 220's departure from the placement groove 212. Simultaneously, it can be understood that when in the avoidance state, it is also used to push the cup assembly 220 along the top surface of the base portion into the placement groove 212 to complete the installation of the cup assembly 220. (Reference) Figure 3 As shown, the boss 211 is located on the top surface of the base portion, and the bottom surface of the placement groove 212 is on the same plane as the top surface of the boss 211. The cup assembly 220 is pushed into the placement groove 212 along the base portion, so that the cup assembly 220 can move smoothly into the placement groove 212 without obstruction, which facilitates the installation of the cup assembly 220.

[0073] In one embodiment, the base portion is provided with a mounting cavity and a first clearance opening communicating with the mounting cavity. The limiting component 240 includes a reset member 241 and a limiting body 242. In the limiting state, the limiting body 242 at least partially passes through the first clearance opening to block the movement of the cup component 220. In the clearance state, the limiting body 242 is located in the mounting cavity. The reset member 241 is connected to the base and the limiting body 242 respectively, and has the tendency to drive the limiting body 242 to switch from the clearance state to the limiting state.

[0074] refer to Figure 14 As shown, the mounting cavity of the base portion is used to accommodate the limiting component 240. Specifically, the limiting body 242 of the limiting component 240 has at least partially extending through the first clearance opening to the top of the base portion to block the cup assembly 220, or the limiting body 242 retracts into the mounting cavity to avoid affecting the movement of the cup assembly 220, thereby realizing the switching of the limiting component 240 between the limiting state and the clearance state. Of course, it is understood that the reset member 241 is used to provide the driving force for the limiting body 242 to switch between the limiting state and the clearance state. In specific implementation, one end of the reset member 241 is connected to the base portion, and the other end is connected to the limiting body 242. When the limiting body 242 is in the clearance state, the reset member 241 is compressed. When it is necessary to switch to the limiting state, the pressing force applied to the reset member 241 is removed, and the reset member 241 drives the limiting body 242 to move under its own elasticity and at least partially extend out of the base portion to abut against the cup assembly 220.

[0075] In one embodiment, the limiting body 242 includes a blocking part 242a and a pressing part 242b. The base part also has a second clearance opening communicating with the mounting cavity. In the limiting state, the blocking part 242a is used to block the movement of the body, and the pressing part 242b extends out of the mounting cavity through the second clearance opening at least partially. Pressing the pressing part 242b causes the limiting body 242 to switch from the limiting state to the clearance state.

[0076] In practical implementation, when the cup assembly 220 is located in the placement groove 212, the blocking part 242a of the limiting body 242 extends through the first clearance opening and blocks the cup assembly 220 from leaving the placement groove 212, thus restricting the cup assembly 220 from moving out of the placement groove 212. Pressing the pressing part 242b drives the blocking part 242a to retract into the mounting cavity, releasing the obstruction on the cup assembly 220 and facilitating the cup assembly 220 to leave the placement groove 212.

[0077] In the specific implementation process, the limiting body 242 is an integral structure. Under the elastic operation of the reset member 241, the blocking part 242a extends out of the mounting cavity through the first clearance opening and the pressing part 242b extends out of the mounting cavity through the second clearance opening. The reset member 241 can be configured as a spring or other elastic structure (such as an elastic block made of elastic material). Furthermore, in order to ensure the smooth movement of the limiting body 242, multiple reset members 241 can be provided.

[0078] In one embodiment, the blocking portion 242a is provided with a first sidewall, which is configured as an inclined surface. (See reference...) Figure 8 As shown, in the specific implementation, the first sidewall is the sidewall of the blocking part 242a opposite to the placement groove 212, so as to push the cup assembly 220 into the placement groove 212. The blocking part 242a is also provided with a second sidewall, which is adapted to the sidewall of the cup assembly 220. In the specific implementation, the cup assembly 220 can be of any shape. The second sidewall fits against the outer peripheral wall of the cup assembly 220 to restrict the movement of the cup assembly 220 away from the placement groove 212. It can also be understood that the blocking part 242a also works with the placement groove 212 to realize the displacement of the cup assembly 220 on the base, ensuring the stability of the cup assembly 220 during the grinding process.

[0079] In one embodiment, the base portion is provided with a support column, which is located inside the mounting cavity. The reset member 241 is sleeved on the outer periphery of the support column, and one end of the support column is provided with a baffle. One end of the reset member 241 abuts against the baffle.

[0080] refer to Figure 16 As shown, one end of the support column is connected to the base and located within the mounting cavity, while the other end extends towards the mounting cavity and is equipped with a baffle. The baffle extends radially along the support column, and the support column corresponds one-to-one with the reset member 241. The limiting body 242 of the limiting assembly 240 has a through hole, through which the support column moves. Additionally, the through hole has a flange, and the reset member 241 is fitted onto the outer periphery of the flange, which helps to fix the reset member 241 and prevent it from shaking, thus affecting compression and elongation. The reset member 241 is movably fitted onto the outer periphery of the support column, with one end of the reset member 241 contacting the limiting assembly 240 and the other end contacting the baffle. When the limiting component 240 is pressed and moved into the mounting cavity, the limiting component 240 presses against the reset component 241, the reset component 241 is compressed, and the blocking part 242a descends into the mounting cavity, facilitating the removal and placement of the cup component 220; when the pressing force is released, the reset component 241, under the action of elasticity, drives the limiting component 240 to rise and reset, causing the blocking part 242a to extend out of the mounting cavity, thus achieving the function of blocking and limiting.

[0081] The base also includes a guide post, which is located within the mounting cavity. The limiting body 242 has a guide hole adapted to the guide post, and the guide post movably passes through the guide hole. Specifically, one end of the guide post is connected to the side of the base facing the mounting cavity, and the other end extends into the mounting cavity. The limiting body 242 has a guide hole, and the limiting body 242 slides, causing the guide post to slide along the guide hole to achieve stable guidance. Additionally, the guide hole has a flange, the inner wall of which surrounds the outer circumference of the guide post, providing stable support for the sliding between the guide post and the guide hole, making the sliding of the guide post within the guide hole more stable. Understandably, to improve the stability of the limiting body 242, multiple sets of guide posts and guide holes are provided to fit together.

[0082] Reference Figure 4 , Figure 7 and Figure 10 In one embodiment, the housing 100 includes an outer shell 120 and an inner shell 110 disposed inside the outer shell 120. The working cavity 111 is formed in the inner shell 110. A cable outlet groove 112 communicating with the working cavity 111 is formed on the inner shell 110, and the cable outlet groove 112 extends in the vertical direction. The ice cream machine 10 also includes a control circuit board 400, which is disposed outside the inner shell 110. The control circuit board 400 is connected to the drive via a wiring assembly 500. The moving component 310 is electrically connected. The upper end of the wire assembly 500 is fixed near the upper end of the wire outlet groove 112. The lower end of the wire assembly 500 passes through the mounting base 210 and is fixed around the outside of the mounting base 210. During the process of the mounting base 210 rising, the wire assembly 500 gradually transitions from an extended, relaxed state to an arc-shaped bent state. While the wire assembly 500 is bending and deforming, it can extend through the wire outlet groove 112 to the outside of the inner shell 110.

[0083] The wire assembly 500 extending from the control circuit board 400 is electrically connected to the drive assembly 310, providing electrical signals to the drive assembly 310. During the vertical movement of the mounting base 210, to prevent the wire assembly 500 from bending or folding within the confined space of the working cavity 111, this design provides a vertically extending cable outlet groove 112 on the inner shell 110. The upper and lower ends of the wire assembly 500 are fixed near the upper end of the cable outlet groove 112 and on the outside of the mounting base 210, respectively. This causes the main body of the wire assembly 500 to gradually bend and bulge towards the cable outlet groove 112 as the mounting base 210 rises from a low position to a high position; and as the mounting base 210 descends from a high position to a low position, the main body of the wire assembly 500 tends to straighten. This avoids problems such as breakage and poor contact caused by excessive bending or winding of the wire assembly 500, thus extending the service life of the wire. At the same time, when the wire assembly 500 is in a bent state, it can extend to the outside of the inner shell 110 through the wire outlet groove 112, preventing the wire from interfering with the movement of the mounting base 210 in the working cavity 111 and improving safety.

[0084] Specifically, the inner shell 110 can be cylindrical or square. Multiple raised ribs can be provided on the wall of the working cavity 111 or the outer wall of the inner shell 110 to improve the overall strength of the inner shell 110. The mounting base 210 has a hollow cubic structure, forming a square mounting space inside. The drive assembly 310 can be fixed to the mounting space with bolts. The container assembly serves as a storage container, used for storing ingredients during the operation of the ice cream machine 10. The control circuit board 400 can be fixed to the external mounting bracket above the inner shell 110 with bolts, used to control the overall operation of the entire ice cream machine 10. It is worth noting that the fixing of the upper and lower ends of the wiring assembly 500 can be done by binding with cable ties or by adhesive bonding; no specific limitation is made here.

[0085] In an embodiment of this invention, when the mounting base 210 is in the raised position, the wire assembly 500 is in a "U"-shaped bend outside the inner shell 110. This makes the deformation path of the wire assembly 500 smoother and more controllable during the lifting and lowering of the mounting base 210. The "U"-shaped structure prevents insulation damage or conductor breakage caused by excessive local bending (such as sharp-angle folding), significantly extending the service life of the wire. In one embodiment, the upper and lower ends of the outlet groove 112 can be rounded, and wear-resistant sleeves can be added to the groove wall of the outlet groove 112 to ensure a smooth transition of the wire assembly 500 when entering and exiting the groove, avoiding scratches. Furthermore, symmetrical arc-shaped limiting ribs can be provided on both sides of the outlet groove 112, with the distance between the two limiting ribs slightly larger than the width of the wire after the "U"-shaped bend. When the mounting base 210 rises, the wire assembly 500 is guided by the limiting ribs to naturally form a "U" shape, preventing the bent portion from swaying or deviating from the preset path.

[0086] In this embodiment of the invention, the mounting base 210 is provided with a lower wire passage, and the top of the inner shell 110 is provided with an upper wire passage. The lower end of the wire assembly 500 that electrically connects to the drive assembly 310 passes through the lower wire passage and extends to the outside of the inner shell 110 through the wire outlet groove 112. The upper end of the wire assembly 500 that electrically connects to the control circuit board 400 passes through the upper wire passage and extends to the outside of the inner shell 110 through the wire outlet groove 112. The lower wire passage can be circular, square, or other irregular shapes. The lower end of the wire assembly 500 is connected to the drive assembly 310 through a crimp terminal. After passing through, the gap between the wire assembly 500 and the lower wire passage is filled with waterproof adhesive (such as silicone sealant) to prevent liquid in the working chamber 111 from seeping into the mounting space inside the mounting base 210. The upper cable entry port can be waist-shaped, "L"-shaped, or "T"-shaped, etc. The edge of the upper cable entry port can be provided with an inwardly folded guide edge to guide the cable assembly 500 smoothly from the cable outlet 112 to the outside. In addition, the upper end of the cable assembly 500 is protected by heat shrink tubing and is fixed to the top of the inner shell 110 with a clip after passing through.

[0087] In this embodiment of the invention, the inner shell 110 is further provided with an upper wire fixing hole, which is located near the top of the cable outlet groove 112. The upper end of the wire assembly 500 is fixed at the upper wire fixing hole. The upper wire fixing hole can be a circular through hole, through which cable ties can be used to bind the wire assembly 500. The upper wire fixing hole is located near the top of the cable outlet groove 112 and works in conjunction with the upper cable threading port to form a double fixation of the upper end of the wire assembly 500. The upper cable threading port is used to guide the path, and the upper wire fixing hole is used to lock the position, eliminating the risk of the wire shaking, tangling, or colliding with the inner shell 110 due to the free swing of the upper end during the lifting and lowering of the mounting base 210, and ensuring that the wire always moves along the predetermined path of the cable outlet groove 112.

[0088] In an embodiment of this utility model, the mounting base 210 is further provided with a lower fixing hole, which is located near the lower wire passage opening. The lower end of the wire assembly 500 is fixed at the lower fixing hole. The lower fixing hole can be a threaded hole or a circular through hole, and it is located near the lower wire passage opening. The wire assembly 500 first passes through the lower wire passage opening into the interior of the mounting base 210, and then a cable tie or steel rope is threaded through the lower fixing hole to bind the lower end of the wire assembly 500. The lower wire passage opening guides the wire path, and the lower fixing hole locks the position, ensuring that the lower end of the wire assembly 500 does not move axially or radially. For example, when the mounting base 210 is raised or lowered, the portion of the wire assembly 500 below the lower fixing hole (the section connecting the drive assembly 310) remains completely stationary, and only the upper portion deforms, avoiding stress on the motor output side.

[0089] In an embodiment of this invention, the ice cream machine 10 further includes a wire wrapping sleeve, which is wound around the outer wall of the wiring assembly 500. The wire wrapping sleeve can be made of materials such as silicone or polyurethane elastomer, and is tightly wound around the outer wall of the wiring assembly 500 to form a flexible protective layer. This layer effectively resists external friction, compression, chemical corrosion, and insulation aging caused by long-term bending. Compared to exposed wires, the wire wrapping sleeve can disperse stress concentration points, preventing localized fatigue damage to the wires during dynamic movement and extending their service life.

[0090] In the embodiments of this utility model, please refer to Figure 7 The outer shell 120 encloses the outer shell 110, and a receiving space is formed between the inner wall of the outer shell 120 and the outer wall of the inner shell 110. The control circuit board 400 is disposed within the receiving space, and the wiring assembly 500 extends into the receiving space through the cable outlet 112. Specifically, the outer shell 120, as an external support component of the ice cream machine 10, can be made of metal or plastic, without limitation; the outer shell 120 can be square or round, without limitation; and the receiving space formed between the outer shell 120 and the inner shell 110 allows the wiring assembly 500 to extend out, preventing it from being folded or bent within the working cavity 111 and shortening its service life. By enclosing the outer shell 120 within the inner shell 110, the drive assembly 310 and the control circuit board 400 within the working cavity 111 are protected, ensuring the normal operation of the stirring or grinding process.

[0091] Reference Figure 4 , Figure 5 and Figure 17 Optionally, the cup assembly 220 includes a cup holder 221 and an ice cup 222. The cup holder 221 has a locking groove 221a, and the ice cup 222 is locked in the locking groove 221a. It can be understood that when installing the ice cup 222, it can be directly locked in the locking groove 221a, thereby preventing relative rotation between the ice cup 222 and the cup holder 221. Of course, this solution is not limited to this. In other embodiments, an installation groove is provided on the cup holder 221, and a connecting structure is provided between the cup holder 221 and the ice cup 222. The ice cup 222 is placed in the installation groove, and the installation structure connects the cup holder 221 and the ice cup 222. This also prevents relative rotation between the ice cup 222 and the cup holder 221.

[0092] Furthermore, the bottom of the cup holder 221 is provided with a plurality of locking protrusions 221b, and the ice cup 222 is provided with a locking recess 222a corresponding to one of the locking protrusions 221b, and an anti-rotation ice groove is formed between any two locking recesses 222a; it can be understood that the food in the ice cup can be a whole piece, and the setting of the anti-rotation ice groove can prevent the food from rotating, which further facilitates the cutting of the food by the stirring blade 630.

[0093] Reference Figure 4 , Figure 6 and Figure 9 In one embodiment, the ice cream machine 10 includes a stirring assembly 600, which includes a rotary drive assembly 610, a drive shaft 620, and a stirring blade 630. The stirring blade 630 includes a blade shaft 631 and a blade body 632 connected together. The blade body 632 is provided with a plurality of blades. The blade shaft 631 is provided with a first magnetic element 631a, and the end face of the blade shaft 631 away from the blade body 632 is provided with a connecting hole 631b. The hole wall of the connecting hole 631b is provided with a first connecting structure 63. 1c, the drive shaft 620 extends in the vertical direction and is drivenly connected to the rotary drive assembly 610. The drive shaft 620 includes a main rod 621 and a second magnetic element 622 disposed at the lower end of the main rod 621. The lower end of the drive shaft 620 is also provided with a second connecting structure 623. The first connecting structure 631c and the second connecting structure 623 are detachably connected. The first magnetic element 631a and the second magnetic element 622 are magnetically connected to connect the cutter shaft 631 and the drive shaft 620.

[0094] The technical solution of this utility model forms a double-fixed connection structure by mechanically connecting the drive shaft 620 and the cutter shaft 631 through the first connecting structure 631c and the second connecting structure 623, combined with the magnetic attraction connection of the first magnetic component 631a and the second magnetic component 622. The first connecting structure 631c and the second connecting structure 623 can ensure that the rotational power of the drive shaft 620 is efficiently transmitted to the cutter shaft 631 to avoid slippage; the magnetic attraction connection enhances the axial fit between the drive shaft 620 and the cutter shaft 631 through magnetic pre-fixation, preventing the cutter shaft 631 from separating from the drive shaft 620 during high-speed rotation. This is especially suitable for scenarios where resistance fluctuations may occur when mixing ice cream ingredients, ensuring continuous and stable operation, and improving the connection stability between the mixing blade 630 and the drive shaft 620 during the process of the mixing blade 630 crushing ingredients. The tight fit between the first magnetic component 631a and the second magnetic component 622, as well as the first connecting structure 631c and the second connecting structure 623, helps reduce power transmission loss and ensures that the rotational power of the drive shaft 620 is directly and evenly transmitted to the blade shaft 631, driving the blades to stir efficiently and avoiding uneven stirring caused by loose connections. The magnetic connection between the blade shaft 631 and the drive shaft 620 has a certain buffering effect, which can absorb slight vibrations during rotation and reduce mechanical collision noise; at the same time, the tightness of the double connection reduces abnormal noise caused by loose parts, making the ice cream machine 10 operate more quietly and smoothly.

[0095] In one embodiment, the drive shaft 620 includes a main rod 621 and a first magnetic component 631a disposed at the lower end of the main rod 621. The main rod 621 and the first magnetic component 631a of the drive shaft 620 are detachable. If the magnetic component weakens due to long-term use, or if the first connecting structure 631c wears due to long-term crushing of food, it is not necessary to replace the entire drive shaft 620; only the first magnetic component 631a needs to be replaced, reducing the cost of parts and facilitating user operation without requiring specialized repair personnel. Similarly, if the second connecting structure 623 or the blade body 632 on the blade shaft 631 is damaged, the stirring blade 630 can be replaced separately without repairing the drive shaft 620, reducing the overall maintenance cost of the machine.

[0096] In one embodiment, the first magnetic component 631a includes a magnetic casting, and the first connecting structure 631c is formed on the magnetic casting. Casting is a method of pouring liquid metal into a casting cavity adapted to the shape of the part, and obtaining the part or blank after cooling and solidification. That is, the first connecting structure 631c is formed on the first magnetic component 631a by casting, which can reduce the technical cost required to process the first connecting structure 631c. In other embodiments, the first connecting structure 631c may also be formed on the first magnetic component 631a by a machining process.

[0097] In one embodiment, the second magnetic element 622 includes a magnet, and the first magnetic element 631a is made of a magnetic metal. This allows the first magnetic element 631a to have a large magnetic attraction force with the second magnetic element 622. Further, the material of the first magnetic element 631a may include neodymium iron boron magnets, samarium cobalt magnets, AlNiCo magnets, etc.

[0098] In one embodiment, the first connecting structure 631c includes a plurality of first oblique protrusions arranged around the axis of the drive shaft 620, the first oblique protrusions extending circumferentially around the drive shaft 620 in the height direction; the second connecting structure 623 includes a plurality of second oblique protrusions arranged around the axis of the coupling hole 631b, the second oblique protrusions extending circumferentially around the coupling hole 631b in the extension direction, and one second oblique protrusion can be coupled to two adjacent first oblique protrusions. When the drive shaft 620 rotates, torque is transmitted to the second oblique protrusions through the first oblique protrusions to drive the rotation of the blade shaft 631. That is, by alternately coupling the multiple first oblique protrusions and the second oblique protrusions along the circumference of the drive shaft 620, multiple sets of contact tooth surfaces are formed, avoiding deformation or breakage between the first connecting structure 631c and the second connecting structure 623 due to local stress concentration between the blade shaft 631 and the drive shaft 620 during the process of the stirring blade 630 pulverizing food. In other embodiments, the first connection structure 631c and the second connection structure 623 may include other coupling structures, which are not limited here.

[0099] Furthermore, the first oblique protrusion has a first abutting slope at one end near the second oblique protrusion, and the second oblique protrusion has a second abutting slope at one end near the first oblique protrusion. During the process of assembling the tool shaft 631 with the drive shaft 620, the drive shaft 620 extends into the mating hole 631b on the tool shaft 631. The first abutting slope on the first oblique protrusion and the second abutting slope on the second oblique protrusion abut against each other, so as to guide the first oblique protrusion between two adjacent second oblique protrusions and abut against the second oblique protrusion. Therefore, when installing the cutter shaft 631 and the drive shaft 620, the first magnetic element 631a and the second magnetic element 622 can pre-position the cutter shaft 631 and the drive shaft 620. The first and second inclined protrusions can guide the two to automatically rotate and align. During use, the user does not need to precisely align the installation angle between the cutter shaft 631 and the drive shaft 620; simply bringing the cutter shaft 631 and the drive shaft 620 closer together will allow the first and second inclined protrusions to couple. In other embodiments, the first and second abutting inclined surfaces may not be provided.

[0100] In one embodiment, the main rod 621 and the first magnetic component 631a are connected by a thread. Therefore, by screwing on the first magnetic component 631a, the first magnetic component 631a can be detached and assembled from the main rod 621, making the operation simple and easy for users to understand and operate. In other embodiments, the main rod 621 and the first magnetic component 631a can also be connected by a snap-fit ​​or fastener.

[0101] In one embodiment, the second magnetic element 622 is exposed on the bottom wall of the connecting hole 631b. This enhances the magnetic connection between the second magnetic element 622 and the first magnetic element 631a, making it less likely for the cutter shaft 631 and the drive shaft 620 to detach axially. In other embodiments, the second magnetic element 622 may be embedded in the bottom of the connecting hole 631b, or it may be exposed on the side wall of the connecting hole 631b.

[0102] In one embodiment, the cutter shaft 631 also has a weight-reduction hole located at the end of the magnetic component away from the mating hole 631b. The diameter of the weight-reduction hole is smaller than the diameter of the second magnetic component 622. The weight-reduction hole reduces the material required to produce the stirring blade 630, thus reducing its weight and allowing for a lightweight design while maintaining sufficient structural strength. Due to the reduced weight of the stirring blade 630, the magnetic attraction between the first magnetic component 631a and the second magnetic component 622 can more easily maintain the cutter shaft 631 mounted on the drive shaft 620. In other embodiments, the weight-reduction hole may not be provided.

[0103] In one embodiment, the weight-reducing hole in the cutter shaft 631 extends from the end face of the magnetic element away from the connecting hole 631b to the cutter body 632, and the weight-reducing hole can more effectively reduce the weight of the stirring blade 630. In other embodiments, the weight-reducing hole may extend from the end face of the magnetic element away from the connecting hole 631b to the middle or bottom of the cutter shaft 631.

[0104] Reference Figure 4 , Figure 6 , Figure 15 , Figure 18 and Figure 19 In one embodiment, the cup device 200 further includes a cup lid 700 for covering the cup assembly 220. The cup lid 700 has a through hole 710, and a plurality of elastic retaining beads 720 are provided in the through hole 710. The elastic retaining beads 720 can extend out of the inner wall of the through hole 710. The outer wall of the cutter shaft 631 can engage with the elastic retaining beads 720, and the cutter shaft 631 is detachably connected to the drive shaft 620.

[0105] Reference Figure 6In the ice cream machine 10, multiple elastic retaining beads 720 within the through hole 710 of the cup lid 700 engage with the blade shaft 631 to hold the mixing blade 630 onto the cup lid 700. During the assembly of the cup lid 700, the drive shaft 620 is inserted into the through hole 710, allowing it to connect with the blade shaft 631. When the ice cream machine is started, the cup assembly 220 moves upward relative to the drive shaft 620. At this time, the drive shaft 620 can engage with the blade shaft 631 within the through hole 710 and exert downward pressure on the blade shaft 631, thereby engaging the blade shaft 631. 1. The blade detaches from the elastic retaining bead 720 on the cup lid 700 and enters the cup assembly 220 of the ice cream machine 10 to crush the ingredients in the cup assembly 220. After crushing the ingredients in the cup assembly 220, the cup assembly 220 moves downward relative to the blade shaft 631, causing the blade shaft 631 to move towards the cup lid 700 within the cup assembly 220. When the blade shaft 631 moves into the through hole 710, it is engaged by the elastic retaining bead 720. After the blade shaft 631 and the cup lid 700 are assembled, the drive shaft 620 and the blade shaft 631 can be detached from each other and removed from the through hole 710. At this time, the stirring blade 630 can be removed from the ice cream machine 10 along with the cup lid 700. This design ensures that the stirring blade 630 only performs its pulverizing function within the cup assembly 220, and is completely contained and restrained by the cup lid 700 when not in use. This eliminates the safety hazard of the stirring blade 630 being exposed in traditional designs, and also eliminates the risk of being cut by the blade when assembling the blade shaft 631 and drive shaft 620. Furthermore, during the process of the stirring blade 630 pulverizing the food in the cup assembly 220, the drive shaft 620 extends into the cup assembly 220 through the through hole 710 of the cup lid 700. After the stirring blade 630 pulverizes the food, the drive shaft 620 disengages from the through hole 710, and the stirring blade 630 is held in place by the elastic retaining ball 720 within the through hole 710. Therefore, the gap between the through hole 710 and the drive shaft 620 remains small to prevent food from splashing out. During the assembly of the cup lid 700, stirring blade 630, and drive shaft 620, the user only needs to snap the stirring blade 630 into the through hole 710, and the ice cream machine 10 can automatically dock and separate the blade assembly from the drive shaft 620 by lifting the cup assembly 220. After stirring, the blade assembly is removed as a whole with the cup lid 700, and can be cleaned without disassembling the blade assembly separately. Its operation is simple and helps to reduce the error rate caused by complicated steps.

[0106] In one embodiment, the elastic retaining bead 720 includes a connecting tube, an elastic element disposed within the connecting tube, and a retaining bead. The connecting tube is embedded in the wall of the through hole 710. The retaining bead is abutted by the elastic element within the connecting tube and abuts against the end face of the connecting tube, and the retaining bead is movable within the connecting tube. Further, a retaining groove is provided on the outer wall of the cutter shaft 631. The retaining groove surrounds the circumference of the cutter shaft 631 and is connected end-to-end, engaging with the elastic retaining bead 720. When the elastic retaining bead 720 engages with the side wall of the retaining groove on the cutter shaft 631, the retaining bead is located at the opening of the connecting tube and extends into the retaining groove. At this time, the retaining bead can move within the retaining groove, that is, the cutter shaft 631 can rotate around the axis of the through hole 710 within the through hole 710. When the retaining bead is pressed by the end face of the retaining groove and moves into the connecting tube, the retaining bead presses against the elastic element. At this time, the retaining bead disengages from the retaining groove, and the cutter shaft 631 can be removed from the cup cover 700. In other embodiments, there may be multiple retaining grooves, which are spaced apart around the circumference of the cutter shaft 631 and are correspondingly set with the elastic retaining beads 720 one by one.

[0107] Reference Figure 18 and Figure 19 In one embodiment, the cup lid 700 includes an upper lid body 730 and a lower lid body 740. The elastic retaining bead 720 is disposed on the upper lid body 730, and the lower lid body 740 is connected to the opening of the cup assembly 220. A lifting component is provided between the upper lid body 730 and the lower lid body 740 to enable the upper lid body 730 to move in the vertical direction, and to have an installation position and a disassembly position. The cutting shaft 631 is detachably installed on the upper lid body 730. In the installation position, the upper lid body 730 is away from the lower lid body 740, and the cutting shaft 631 is assembled with the drive shaft 620. In the disassembly position, the upper lid body 730 is close to the lower lid body 740, and the cutting shaft 631 is detached from the drive shaft 620.

[0108] The technical solution of this utility model assembles the blade shaft 631 with the upper cover 730, and automatically assembles the blade shaft 631 with the drive shaft 620 by lifting the upper cover 730 upwards, and automatically disassembles the blade shaft 631 with the drive shaft 620 by moving the upper cover 730 downwards. That is, during the assembly and disassembly of the mixing blade 630 and the drive shaft 620, the user does not need to manually touch the mixing blade 630; only the position of the upper cover 730 needs to be moved, eliminating the risk of fingers being cut by the blades during the assembly of the blade shaft 631 and the drive shaft 620. Furthermore, its assembly and disassembly process is simple, making the operation process easy for users to understand and use.

[0109] In one embodiment, the lifting assembly includes a snap-fit ​​protrusion 751 on the outer side wall of the lower cover 740 and a lifting groove 752 on the inner side wall of the upper cover 730. The snap-fit ​​protrusion 751 is disposed near the top wall of the lower cover 740, and the lifting groove 752 extends vertically, allowing the snap-fit ​​protrusion 751 to slide within it. The lifting groove 752 restricts and guides the movement trajectory of the upper cover 730. In the installation position, the snap-fit ​​protrusion 751 is located at the bottom of the lifting groove 752, at which point the upper cover 730 moves upward to approach the drive shaft 620, enabling the drive shaft 620 to connect with the cutter shaft 631. In the disassembly position, the snap-fit ​​protrusion 751 is located at the top of the lifting groove 752, at which point the upper cover 730 moves downward to disengage the cutter shaft 631 from the drive shaft 620. In other embodiments, a plurality of latches distributed at intervals along the height direction may be provided between the upper cover 730 and the lower cover 740 to allow the upper cover 730 to rise or fall relative to the lower cover.

[0110] In one embodiment, the lifting slide 752 includes a sliding section extending obliquely around the upper cover 730 in a vertical direction, and an abutment section extending horizontally around the upper cover 730. The abutment section is located at one end of the sliding section near the bottom of the upper cover 730. That is, in the disassembled position, the user can rotate the upper cover 730 about its own axis in a positive direction to make the sliding section on the upper cover 730 slide against the snap-fit ​​protrusion on the lower cover 740. At this time, the upper cover 730 is lifted relative to the lower cover 740 to move to the installation position. When moved to the installation position, the snap-fit ​​protrusion 751 abuts against the abutment section and is located at the end of the abutment section away from the sliding section. In the installation position, the user can rotate the upper cover 730 about its own axis in a negative direction to make the abutment section slide away from the snap-fit ​​protrusion 751, so that the snap-fit ​​protrusion 751 slides against the sliding section until the snap-fit ​​protrusion 751 is located at the top of the sliding section. At this time, the upper cover 730 is in the disassembled position. It should be noted that when the mixing blade 630 crushes the ingredients in the cup of the ice cream machine 10, the resistance fluctuations that may occur in the mixing blade 630 can transmit vibrations to the cup lid 700. In this case, placing the locking protrusion 751 at the end of the abutment section away from the sliding section can prevent the lid 730 from slipping out of its installation position due to vibration. Furthermore, the lifting groove 752 is provided with a resisting locking protrusion located in the abutment section and close to the sliding section to prevent the locking protrusion 751, which abuts against the abutment section, from slipping into the sliding section due to vibration, thus preventing the lid 730 from detaching from its installation position. When the user needs to move the lid 730 to the disassembly position, they can manually rotate the lid 730 in the opposite direction to apply a force that disengages the locking protrusion 751 from the resisting locking protrusion. In other embodiments, the resisting locking protrusion may not be provided.

[0111] In one embodiment, multiple lifting grooves 752 and snap-fit ​​protrusions 751 are provided and spaced apart around the axis of the cup lid 700, with each lifting groove 752 corresponding to a snap-fit ​​protrusion 751. This provides multiple support structures for the movable upper cover 730, enabling the upper cover 730 to move stably between the installation position and the removal position. In other embodiments, only two lifting grooves 752 and two snap-fit ​​protrusions 751 may be provided, with the two lifting grooves 752 arranged opposite to each other.

[0112] In one embodiment, a handle protrusion is provided on the outer side wall of the upper cover 730. The user can rotate the upper cover 730 forward or backward by gripping the handle protrusion. Further, a locking indicator is provided on the right side of the handle protrusion to indicate to the user that rotating the handle protrusion to the left (i.e., rotating the upper cover 730 forward) can move the upper cover 730 to the installation position for assembling the cutter shaft 631 and drive shaft 620; an unlocking indicator is provided on the left side of the handle protrusion to indicate to the user that rotating the handle protrusion to the right (i.e., rotating the upper cover 730 backward) can move the upper cover 730 to the disassembly position for detaching the cutter shaft 631 and drive shaft 620. In other embodiments, the handle protrusion may not be provided, or the unlocking and locking indicators may not be provided.

[0113] In one embodiment, a through hole 710 is provided in the middle of the top wall of the upper cover plate, through which the blade shaft 631 passes and is engaged by a plurality of elastic retaining beads 720. That is, the stirring blade 630 is fixed to the cup lid 700 by the elastic retaining beads 720. In other embodiments, it can also be fixed to the cup lid 700 by a magnetic assemblies.

[0114] In one embodiment, the ice cream machine 10 further includes a sensor assembly. A sensing protrusion is provided on the side of the upper cover 730 near the sensor assembly. In the installation position, the sensing protrusion is positioned opposite to the sensor assembly. At this time, the sensor can detect that the upper cover 730 is in the installation position. That is, the control module in the ice cream machine 10 can determine that the drive shaft 620 and the cutter shaft 631 are assembled. At this point, the cup in the ice cream machine 10 can be moved upwards, so that the drive shaft 620 exerts downward pressure on the cutter shaft 631, causing the cutter shaft 631 to reverse-pressure the elastic retaining bead 720, disengaging downwards from the through hole 710 and entering the cup to crush the ingredients placed in the cup. It should be noted that if the sensor assembly does not detect that the upper cover 730 is in the installation position, even if the control module of the ice cream machine 10 receives a user-input command to crush the ingredients in the cup, it will not lift the cup upwards, thereby preventing the drive shaft 620 from rotating on its own and damaging the cutter shaft 631. In other embodiments, the upper cover 730 may also have sensing protrusions, allowing the sensor assembly to detect the height of the upper cover 730 itself.

[0115] Furthermore, the handle protrusion and the sensor protrusion are located on opposite sides of the upper cover 730. The handle protrusion is positioned close to the switch door of the ice cream machine 10 for user convenience. The sensor assembly is located on the side wall of the ice cream machine 10 directly opposite the switch door, allowing the user to easily observe the relative position of the sensor assembly and the sensor protrusion, thus facilitating maintenance of the ice cream machine 10. In other embodiments, the sensor protrusion and the handle protrusion may also be located on adjacent sides of the upper cover 730.

[0116] In one embodiment, the sensor assembly includes a Hall sensor, and a magnetic element is provided within the sensing bump. That is, when the sensing bump is facing the sensor assembly, the magnetic field detected by the sensor assembly conforms to a preset value, thereby transmitting a signal to the control module of the ice cream machine 10. In other embodiments, the sensor assembly may also be an infrared sensor, which is not limited here.

[0117] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
