Description

Technical Field

[0001] This utility model relates to the field of ice cream processing, and in particular to an ice cream machine drive device and an ice cream machine thereof. Background Technology

[0002] Existing ice cream mixers typically use a single-stage geared motor to directly drive the mixing blades when processing hard frozen ice cream. The blades can only rotate around a fixed axis, failing to apply a progressive vertical cutting force to the bottom of the cup and the layered ice cream. This results in large ice crystals not being adequately broken up, low mixing efficiency, and a tendency to jam. Furthermore, the motor support and guide structure are separately arranged, leading to radial offset of the output shaft during long downward strokes, causing blade wear, increased noise, and even seal failure. Therefore, there is an urgent need for a drive device that can provide both high-torque rotation and smooth lifting to achieve efficient and reliable mixing of hard ice cream. Utility Model Content

[0034] Furthermore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and not for limiting the scope of the invention. The term "and / or" as used herein includes any combination of one or more of the associated listed items.

[0035] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0036] Reference Figures 1 to 16 As shown, this utility model discloses an ice cream machine drive device, which includes: Reference Figures 1 to 5 The first bracket 1300 shown has a first through hole and is located inside the ice cream machine. The first bracket 1300 is fixedly connected to the base 1000, and the base and the first bracket can be connected by conventional fasteners such as bolts.

[0037] Continue to refer to Figures 2 to 10 As shown, a second bracket 1400 is positioned above the first bracket 1300. The side edge of the second bracket 1400 is fixedly connected to the first bracket 1300 via multiple support columns 1430. Multiple guide rods 1410 and screws 1420 are provided between the first bracket 1300 and the second bracket 1400. The guide rods 1410 and screws 1420 of the first and second brackets are used for assembly with the motor structure below.

[0038] Reference Figures 2 to 10 The motor mechanism 2000 shown includes a motor bracket 2100, a second motor 2200 mounted on the motor bracket 2100, a gearbox assembly 2300, and an output shaft 2400. This motor assembly drives the output shaft to move along the inner bottom wall of the mixing cup. The stirring blade assembly connected to the end of the output shaft 2400 can rotate and stir the hard, fixed ice cream layer by layer towards the inner bottom wall of the mixing cup into a smooth consistency. The specific drive structure is as follows (see reference). Figures 3 to 6 As shown, the motor bracket 2100 is sleeved on the guide rod 1410, the first end of the output shaft 2400 is rotatably connected to the motor bracket 2100, and the power output end of the second motor 2200 is connected to the power input end of the gearbox assembly 2300. The second end of the output shaft 2400 passes through the first through hole, and the power output end of the gearbox assembly 2300 is threadedly connected to the screw 1420 to allow the motor mechanism 2000 to drive the second end of the output shaft 2400 to move up and down in the first through hole.

[0039] Specifically, in the initial state, the motor bracket 2100, the second motor 2200, and the gearbox assembly 2300 are located near the bottom end of the second bracket 1400. When the hard ice cream inside the mixing cup needs to be broken down layer by layer from the surface to the bottom by the mixing blades, the power output from the second motor 2200 is changed through the gearbox assembly 2300. The gearbox assembly 2300 can then output power to the screw 1420 via gears, thus causing the second motor 2200 to move gradually closer to the first bracket 1300 along with the output shaft 2400. The mixing blades at the end of the output shaft 2400 break down and fix the ice cream layer by layer. After the breaking down operation is completed, the second motor 2200 reverses its output power, and the gearbox assembly 2300 changes speed again. The gearbox assembly 2300 can then output power to the screw 1420 via gears, thus causing the second motor 2200 to move gradually closer to the second bracket 1400 along with the output shaft 2400, completing the reset of the mixing blades. That is, the aforementioned output shaft 2400 can move between the second bracket 1400 and the first bracket 1300 along with the second motor 2200. Similarly, the end of the output shaft 2400 drives the stirring blade to move up and down inside the stirring body to participate in the stirring operation.

[0040] In the initial state of the ice cream mixer, the cup body is assembled on the mixer, and the motor mechanism is located below the second support. When it is necessary to raise or lower the solid ice cream inside the cup, the mixing blade assembly connected to the output shaft of the motor mechanism can rotate and mix the hard, fixed ice cream layer by layer towards the inner bottom wall of the cup body, turning it into a paste. This allows the ice cream machine to fully mix the hard, solid ice cream inside the cup. The following describes other drive mechanisms for mixing the ice cream inside the mixing cup. Furthermore, when the screw of the second motor rotates, driving the output shaft downwards, the motor support, sleeved on multiple guide rods, maintains a stable path, ensuring that the output shaft maintains linear movement over a long period.

[0041] Reference Figures 3 to 5 As shown, a pair of guide rods 1410, an output shaft 2400, and a screw 1420 are spaced apart between the first bracket 1300 and the second bracket 1400, with the output shaft 2400 and screw 1420 positioned between the pair of guide rods 1410. This motor bracket ensures that both sides can engage with guide rails, and the two guide rails constrain the sides of the motor bracket, guaranteeing optimal linear movement of the output shaft.

[0042] Reference Figure 6 As shown, the gearbox assembly 2300 includes a first gearbox 2310, a planetary gearbox 2320, and a second gearbox 2330. The main body of the motor is connected to the housing of the first gearbox 2310. The motor shaft of the second motor 2200 is connected to the power input end of the first gearbox 2310. The housing of the first gearbox 2310 is connected to the housing of the planetary gearbox 2320. The power output end of the first gearbox 2310 is connected to the power input end of the planetary gearbox 2320. The housing of the planetary gearbox 2320 is connected to the housing of the second gearbox 2330. The power output end of the planetary gearbox 2320 is connected to the input end of the second gearbox 2330. The power output end of the second gearbox 2330 is sleeved on the screw 1420. Since stirring and fixing ice cream requires a large torque, the output shaft of the second motor passes through three gearboxes in sequence, causing the gears of the second gearbox 2330 to be threadedly connected to the screw 1420, thus enabling the entire motor structure to drive the output shaft downwards.

[0043] In some implementations, the second motor 2200 and the planetary gearbox 2320 are arranged side by side. This makes the layout of the motor and the planetary gearbox more reasonable.

[0044] Reference Figure 8As shown, a sleeve shaft 1320 is rotatably connected to the first through hole. The sleeve shaft 1320 has a polygonal groove 1321. The outer contour shape of the output shaft 2400 matches the cross-sectional shape of the polygonal groove 1321, and the output shaft 2400 is inserted into the polygonal groove 1321. The outer periphery of the sleeve shaft is circular, which is fitted to the first through hole on the first bracket 1300.

[0045] Reference Figure 10 As shown, the planetary gearbox 2320 includes planetary gear units 2321 and a ring gear 2322 stacked sequentially. Multiple planetary gear units 2321 are disposed within the ring gear 2322, and the driven gear portion of each planetary gear unit 2321 meshes with the ring gear 2322. The power input end of the planetary gearbox 2320 is connected to the first gearbox 2310 via a rotating shaft, and the power output end of the planetary gearbox 2320 is connected to the second gearbox 2330 via a rotating shaft. The stacked structure of the planetary gearbox 2320 further enhances the conversion of torque to the drive shaft, resulting in a greater downward torque on the output shaft and better performance in crushing solid ice cream. Reference Figure 3 As shown, the end of the support column 1430 is provided with a plug-in interface 1431, and the first bracket 1300 is provided with a plug-in seat 1330. The outer contour shape of the plug-in seat 1330 matches the shape of the plug-in interface 1431. This facilitates the assembly personnel to connect the support column and the plug-in seat.

[0046] Continue to refer to Figure 3 As shown, the end of the support column 1430 is provided with a positioning notch 1432, and the plug-in seat 1330 is provided with a positioning block 1331. The shape of the positioning notch 1432 matches the shape of the positioning block 1331. This makes the connection between the support column and the plug-in seat more stable and less prone to displacement.

[0047] In some embodiments, the side housing of the second bracket 1400 is provided with reinforcing ribs 1490.

[0048] Reference Figures 1 to 16 As shown, this utility model also discloses an ice cream mixer, which includes: the ice cream machine drive device as described above.

[0049] The ice cream maker includes: a base 1000 for assembling with a first motor, and a first motor 1200 vertically mounted on the base 1000 for driving the output shaft connected to the mixing blade to rotate, thereby mixing frozen, hard ice cream in the mixing cup into a mushy consistency for consumption.

[0050] Reference Figures 1 to 5As shown, a first bracket 1300 is fixedly connected to the base 1000, and the base and the first bracket can be connected by conventional fasteners such as bolts. A second bracket 1400 is disposed above the first bracket 1300, and the first bracket 1300 is inclined relative to the base 1000. A first through hole is provided on the first bracket 1300, and a guide rod 1410 and a screw 1420 are disposed between the first bracket 1300 and the second bracket 1400. The guide rod 1410 and the screw 1420 of the first and second brackets are used to assemble with the motor structure below.

[0051] The aforementioned ice cream machine transmits power through a first motor driven by a base, which in turn drives an output shaft. This causes the mixing blade assembly connected to the output shaft to churn the hard, solid ice cream. Combined with the motor mechanism, the mixing blade assembly at the end of the output shaft rotates and churns the hard, solid ice cream layer by layer towards the inner bottom wall of the mixing cup, creating a smooth paste. This allows the ice cream machine to thoroughly churn the hard, solid ice cream within the cup. Furthermore, the tilted design of the first support relative to the base provides the user with more control over the connection between the cup and the ice cream machine.

[0052] Reference Figures 1 to 5 The housing assembly 1500 shown includes a first housing 1510 and a substrate 1520. The bottom of the first housing 1510 is integrally connected to the substrate 1520, and the first housing 1510 covers the base 1000, the first support 1300 and the second support 1400.

[0053] Reference Figure 11 As shown, a protrusion 4100 is provided on the outer surface of the cup body 4000. (Refer to...) Figures 1 to 12 As shown, the connecting component 5000 is disposed on the first housing 1510. The connecting component 5000 includes a mounting ring 5100 disposed on the first housing 1510 around the stirring blade assembly 3000, a snap-fit ​​ring 5200 sleeved on the inner ring of the mounting ring 5100, and a ninth elastic member 5300. The snap-fit ​​ring 5200 is provided with snap-fit ​​members 5210 at intervals, and the mounting ring 5100 is provided with mounting openings 5110 at intervals. The snap-fit ​​members 5210 are provided corresponding to the mounting openings 5110. The snap-fit ​​ring 5200 is connected to the ninth elastic member 5300.

[0054] The user assembles the 4100 protrusion on the cup body. Figure 9After the mounting port 5110 is in the middle, the snap ring 5200 overcomes the damping force of the ninth elastic element 5300 within the mounting ring 5100. The snap ring 5200 rotates relative to the mounting ring 5100 within the mounting ring 5100. Finally, the cup body 4000 is engaged with the snap ring 5210 through the protrusion 4100 in the mounting port 5110, making it more convenient for the user to assemble the cup body for use on the ice cream machine.

[0055] Reference Figure 1 As shown, the first housing 1510 includes a vertical housing portion and an inclined housing portion. To enhance the strength of the ice cream mixer, the extension of the mounting ring 5100 is fixedly connected to the bottom of the vertical housing portion and the inclined housing portion. The vertical housing portion and the inclined housing portion around the mixing cup are strengthened by the engaging connection of the extension of the mounting ring 5100, and by bolt installation or other methods.

[0056] Reference Figure 2 As shown, the transmission assembly 900 includes a first transmission gear 910 and a second transmission gear 920 meshing with the first transmission gear 910. The first transmission gear 910 is sleeved on the top shaft of the first motor 1200, and the second transmission gear 920 is sleeved on the output shaft 2400. The two transmission gears in the figure are inclined together, so that the vertically positioned first motor transmits power to the two transmission gears through the vertical motor shaft as the power output end, and the similarly inclined output shaft stirs the solid ice cream.

[0057] Continue to refer to Figure 2 As shown, in order to increase the torque output of the first motor, the first motor is connected to the main gearbox via a shaft drive. The transmission assembly 900 includes a main gearbox 930, which is disposed on the top of the base 1000. The top shaft of the first motor 1200 is connected to the power input end of the main gearbox 930, and the power output end of the main gearbox 930 is connected to the shaft connecting the first transmission gear 910.

[0058] Reference Figures 11 to 16As shown, the connecting assembly 5000 includes a press button 5400, which is slidably connected to the mounting ring 5100. A first inclined surface 5410 is provided at the bottom end of the press button 5400, and a second inclined surface 5420 is provided on the mounting ring 5100. The first inclined surface 5410 and the second inclined surface 5420 are correspondingly arranged. When the surface of the press button 5400 is pressed, the first inclined surface 5410 and the second inclined surface 5420 are pressed together, allowing the locking ring 5200 to rotate relative to the mounting ring 5100, thus unlocking the protrusion 4100 from the locking member 5210. When the user presses the pressing button 5400, the pressing button 5400 contacts and squeezes the second inclined surface 5420 on the mounting ring 5100 through the first inclined surface 5410, forcing the pressing button 5400 to force the locking ring 5200 to rotate relative to the mounting ring 5100, so that the protrusion 4100 on the cup body is unlocked from the locking piece 5210 on the locking ring 5200, making it convenient for the user to remove the cup body from the main body of the ice cream machine.

[0059] Continue to refer to Figure 12 As shown, the snap-fit ​​component 5210 is provided with a ninth inclined surface 5219, which corresponds to the mounting port 5110. After the cup body 4000 is installed by aligning the protrusion 4100 with the mounting port 5110, the snap-fit ​​component 5210 makes the contact with the protrusion 4100 through the ninth inclined surface 5219, resulting in a smoother snap-fit ​​connection.

[0060] Continue to refer to Figures 11 to 16 As shown, a cover 6000 is disposed between the first support 1300 and the cup body 4000 for covering the upper opening of the cup body 4000. The cover 6000 has an internal mounting cavity and a mounting hole in its center. This cover is used to assemble the following mixing blade assembly and to connect to the ice cream machine body, enabling a drive connection between the output shaft 2400 and the mixing blade holder. The mixing blade is used to crush solid ice cream.

[0061] Continue to refer to Figure 13 As shown, the stirring blade assembly 3000 includes a stirring blade holder 3100 and a stirring blade 3200 connected to the stirring blade holder 3100. The stirring blade holder 3100 is connected to the mounting hole, and the stirring blade holder is detachably connected to the mounting hole.

[0062] Continue to refer to Figures 11 to 16As shown, a locking assembly 7000 is disposed inside the cover 6000. The locking assembly 7000 includes a locking member 7100, a second elastic member 7200, and a guide member 7300. The guide member 7300 is vertically inserted into the cover 6000. The locking member 7100 has a third inclined surface 7110, and the guide member 7300 has a fourth inclined surface 7310. The third inclined surface 7110 and the fourth inclined surface 7310 are in corresponding contact. The two ends of the second elastic member 7200 are respectively connected to the first end of the locking member 7100 and the interior of the cover 6000. When the cover and cup are assembled but not yet mounted on the ice cream machine body, i.e., in the initial locked state of the cover and cup, the second end of the locking member 7100 abuts against the surface of the stirring blade holder 3100, preventing the stirring blade holder from rotating and ensuring that the stirring blade is locked and does not operate during non-stirring operations. When the lid and cup are assembled onto the main body of the ice cream machine, and when the stirring blade holder 3100 is to be unlocked so that it can be rotated by the output shaft, refer to... Figures 11 to 14 As shown, the protruding end of the guide member 7300 is on the base plate of the ice cream machine. The guide member 7300 is pressed by the external force of the base plate, forcing the other end of the locking member 7100 away from the mixing blade holder 3100. The mixing blade holder 3100 is then unlocked by moving away from the second end of the locking member 7100, and the mixing blade holder 3100 can be rotated by the output shaft in an unlocked state.

[0063] Reference Figure 13 As shown, a limiting hole 6100 is provided on the cover 6000, the limiting hole 6100 is provided corresponding to the stirring blade holder 3100, and the second end of the locking member 7100 is provided corresponding to the limiting hole 6100. The second end of the locking member, in conjunction with the limiting hole, ensures that the locking member does not deviate.

[0064] Reference Figure 6As shown, the gearbox assembly 2300 includes a first gearbox 2310, a planetary gearbox 2320, and a second gearbox 2330. The main body of the second motor 2200 is connected to the housing of the first gearbox 2310, the motor shaft of the second motor 2200 is connected to the power input end of the first gearbox 2310, the housing of the first gearbox 2310 is connected to the housing of the planetary gearbox 2320, the power output end of the first gearbox 2310 is connected to the power input end of the planetary gearbox 2320, the housing of the planetary gearbox 2320 is connected to the housing of the second gearbox 2330, the power output end of the planetary gearbox 2320 is connected to the input end of the second gearbox 2330, and the power output end of the second gearbox 2330 is sleeved on the screw 1420. Since stirring and fixing ice cream requires a large torque, the motor output shaft of the second motor passes through three gearboxes in sequence, causing the gears of the second gearbox 2330 to be threadedly connected to the screw 1420, thus enabling the entire motor structure to drive the output shaft downwards.

[0065] In some implementations, the second motor 2200 is arranged side by side with the planetary gearbox 2320.

[0066] Continue to refer to Figures 11 to 16 As shown, it also includes: a cup body 4000, on the outer surface of which a plurality of first slots 4200 are spaced apart. The locking element provided on the lid 6000 is for engaging with the first slots 4200 to complete the detachable connection between the cup body and the lid.

[0067] Continue to refer to Figures 11 to 16As shown, the locking assembly 7000 includes a first limiting member 7400 and a third elastic member 7500. The inner sidewall of the cover 6000 is provided with a mounting groove 6200 and a locking member 6300. The first limiting member 7400 is slidably connected to the mounting groove 6200. The two ends of the third elastic member 7500 are respectively connected to the first end of the first limiting member 7400 and the interior of the cover 6000. The first limiting member 7400 is provided with a fifth inclined surface 7410, and the guide member 7300 is provided with a sixth inclined surface 7310. The fifth inclined surface 7410 and the sixth inclined surface 7310 are in corresponding contact. When the guide member 7300, in conjunction with the locking member 7100, moves away from the limiting hole 6100, it also forces the fifth inclined surface 7410 and the sixth inclined surface 7310 to contact and lift the first limiting member 7400. A second limiting member 4300 is provided on the outer side of the cup body 4000. When the locking member 6300 engages with the first bayonet 4200, the second end of the first limiting member 7400 contacts the second limiting member 4300, and the first limiting member 7400 slides upward along the mounting groove 6200, overcoming the resistance of the third elastic member 7500. When this structure is applied to the assembly of the lid and cup, the locking member 7100 unlocks away from the limiting hole 6100.

[0068] Reference Figure 12 As shown, a first limiting member 7400 is provided inside the mounting ring 5100, and the first limiting member 7400 is a component inside the lid body. A ninth limiting member 5290 is provided on the snap-fit ​​ring 5200, and a ninth elastic member 5300 is disposed between the first limiting member 7400 and the ninth limiting member 5290 and abuts against each other. The ninth elastic member 5300 is a spring, which causes the snap-fit ​​ring 5200 to rotate relative to the mounting ring 5100. The spring at this location causes the snap-fit ​​ring 5200 to return to its original position, facilitating the snap-fit ​​connection between the cup body and the ice cream mixer.

[0069] Reference Figure 15 As shown, the inner surface of the cover 6000 is provided with a guide rail 6400, the moving direction of the guide rail 6400 is towards the stirring blade holder 3100, and the locking member 7100 is slidably connected to the guide rail 6400. This is to ensure that the locking member 7100 and the guide rail 6400 are properly engaged and slidably connected, preventing displacement.

[0070] Reference Figure 13 As shown, the mixing blade holder 3100 has a transmission mounting port 3110. The inner wall of the transmission mounting port 3110 is provided with protruding inclined portions 3120 for transmission connection with the output shaft 2400 of the ice cream machine. The transmission mounting port 3110 of the mixing blade holder 3100 is used for transmission connection with the end of the output shaft, and the inclined portions 3120 on the inner wall of the transmission mounting port 3110 facilitate a more secure connection between the output shaft and the mixing blade holder 3100.

[0071] Reference Figure 13 As shown, a limiting groove 3130 is formed on the outer side of the stirring blade holder 3100, and the limiting groove 3130 is provided at the second end of the locking member 7100. The limiting groove 3130 and the locking member 7100 are matched to make locking or unlocking more precise.

[0072] Reference Figure 15 As shown, the outer side wall of the cover 6000 is provided with a planar grip portion 6500. Using the grip portion with a planar orientation provides a more secure grip.

[0073] Reference Figure 13 As shown, a stirring blade 3200 is connected to one side of the stirring blade holder 3100, and the stirring blade 3200 is located inside the cup body 4000.

[0074] To ensure the solid ice cream inside the cup remains stable and adheres to the inside of the cup during the churning process, refer to... Figure 14 As shown, the inner sidewall of the cup body 4000 is provided with protrusions 4400 arranged circumferentially and at intervals, and the inner bottom wall of the cup body 4000 is provided with multiple grooves 4500. The protrusions and grooves increase the unevenness of the inner wall of the cup body, so that the solid ice cream inside the cup body can be stably stuck to the inside of the cup body during the process of being stirred into a paste, and prevent the solid ice cream from rotating with the stirring blade during the stirring process.

[0075] In some implementations, a gap is left between the snap-fit ​​portion of the snap-fit ​​member 5210 and the mounting port 5110. This gap ensures that the cup body can stably maintain a certain perpendicularity to the mounting port of the ice cream mixer.

[0076] In some implementations, the cup body engages with multiple positions on the ice cream machine, see reference. Figure 12 As shown, the snap ring 5200 is provided with three snap fasteners 5210 at intervals, and the outer side of the cup body 4000 is provided with three protrusions 4100 corresponding to the snap fasteners 5210.
