Description

Technical Field

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

[0002] Most ice cream machines on the market have a refrigeration function, grinding ice into a smoothie by simultaneously cooling and mixing. They typically consist of a main unit, a drive shaft, a filling structure, and a cup holder. The drive shaft is mounted on the main unit, which houses a drive motor to rotate it. The filling structure is mounted on the cup holder and contains a blade assembly. The drive motor moves the cup holder up and down, engaging or disengaging the blade assembly from the drive shaft, thus completing the mixing process.

[0003] However, the operation of the drive motor usually relies on an external circuit board to provide control signals or power supply, which inevitably requires the use of multiple wires to connect the circuit board and the drive motor. Because the cup holder needs to frequently rise and fall during operation, these wires will be repeatedly folded, bent, and even stacked. Over long-term use, the wires are susceptible to mechanical stresses such as compression and stretching, leading to problems such as damaged insulation, broken internal wires, or poor contact, thus reducing the lifespan of the wires. Utility Model Content

[0004] The main purpose of this invention is to propose an ice cream machine that solves the problem of repeated folding and bending of the motor wires in existing ice cream machines during the lifting and lowering of the cup seat.

[0005] To achieve the above objectives, the present invention provides an ice cream machine, which includes: The inner shell has a working cavity inside, and a cable outlet groove communicating with the working cavity is provided on the inner shell, and the cable outlet groove extends in the vertical direction; A material holding structure is movably disposed within the working chamber. The material holding structure includes a cup holder and a container assembly. The container assembly is detachably mounted on the cup holder, and the interior of the cup holder forms an installation space. A drive motor, located within the mounting space, is connected to the cup holder to drive the cup holder to move up and down within the working chamber; and A control circuit board is located outside the inner shell. The control circuit board is electrically connected to the drive motor through 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 cup holder and is fixed around the outside of the cup holder. As the cup holder rises from a low position to a high position, 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.

[0006] In one embodiment, when the cup holder is in the raised high position, the wiring assembly is in a "U"-shaped bend outside the inner shell.

[0007] In one embodiment, the cup holder is provided with a lower wire pass-through port, and the top of the inner shell is provided with an upper wire pass-through port. The lower end of the wire assembly electrically connected to the drive motor passes through the lower wire pass-through port and extends to the outside of the inner shell through the wire outlet groove. The upper end of the wire assembly electrically connected to the control circuit board passes through the upper wire pass-through port and extends to the outside of the inner shell through the wire outlet groove.

[0008] In one embodiment, the inner shell is further provided with an upper wire fixing hole, which is located near the top of the wire outlet groove, and the upper end of the wire assembly is fixed at the upper wire fixing hole.

[0009] In one embodiment, the cup holder is further provided with a lower wire fixing hole, which is located near the lower wire insertion port, and the lower end of the wire assembly is fixed at the lower wire fixing hole.

[0010] In one embodiment, the ice cream machine further includes a wire winder wrapped around the outer wall of the wire assembly.

[0011] In one embodiment, the ice cream machine further includes a housing that surrounds the outer shell of the inner shell, and a receiving space is formed between the inner wall of the housing and the outer wall of the inner shell. The control circuit board is disposed in the receiving space, and the wiring assembly extends through the cable outlet into the receiving space.

[0012] In one embodiment, the ice cream machine further includes a rotating shaft and a blade assembly. The rotating shaft is rotatably disposed at the top of the working chamber, and the blade assembly is mounted on one end of the container assembly near the rotating shaft. The blade assembly moves synchronously with the container assembly towards or away from the rotating shaft.

[0013] In one embodiment, the container assembly includes a cup body and a cup lid, the cup lid being detachably mounted at the rim of the cup body, the cutter assembly being mounted on the cup lid, and the cup body being detachably mounted on the cup holder.

[0014] In one embodiment, a limiting protrusion is provided on one of the inner wall of the cup holder and the outer wall of the cup body, and a limiting groove is provided on the other of the inner wall of the cup holder and the outer wall of the cup body, and the limiting protrusion cooperates with the limiting groove.

[0015] In one embodiment, a rotating buckle is provided on one of the inner wall of the cup lid and the outer wall of the cup body, and a rotating groove is provided on the other of the inner wall of the cup lid and the outer wall of the cup body. When the cup lid is placed on the mouth of the cup body, the rotating buckle engages in the rotating groove.

[0016] In this invention, the wiring assembly extending from the control circuit board is electrically connected to the drive motor, providing electrical signals to the motor. To prevent the wiring assembly from bending or folding within the confined space of the working cavity during the rising or falling of the cup holder, a vertically extending cable outlet groove is provided on the inner shell. The upper and lower ends of the wiring assembly are fixed near the upper end of the cable outlet groove and on the outside of the cup holder, respectively. This causes the main body of the wiring assembly to gradually bend and bulge towards the cable outlet groove as the cup holder rises from a low position to a high position; conversely, as the cup holder falls from a high position to a low position, the main body of the wiring assembly tends to straighten. This avoids breakage and poor contact caused by excessive bending or tangling of the wiring assembly, extending its service life. Furthermore, when bent, the wiring assembly can extend to the outside of the inner shell through the cable outlet groove, preventing interference between the wiring and the movement of the cup holder within the working cavity and improving safety.

[0024] In existing ice cream machines, the drive motor typically relies on an external circuit board for control signals or power supply. This inevitably requires multiple wires to connect the circuit board and the drive motor. Because the cup holders frequently rise and fall during operation, these wires are repeatedly folded, bent, and even stacked. Over time, the wires are susceptible to mechanical stresses such as compression and stretching, leading to problems like damaged insulation, broken internal wires, or poor contact, thus reducing their lifespan.

[0025] This utility model proposes an ice cream machine.

[0026] Please see Figures 2 to 4 In one embodiment of this utility model, the ice cream machine 100 includes: The inner shell 1 has a working cavity inside, and a cable outlet groove 11 that communicates with the working cavity is provided on the inner shell 1. The cable outlet groove 11 extends in the vertical direction. The material holding structure 2 is movably disposed in the working chamber. The material holding structure 2 includes a cup holder 21 and a container assembly 22. The container assembly 22 is detachably mounted on the cup holder 21, and the interior of the cup holder 21 forms an installation space. Drive motor 3, located within the installation space, is connected to cup holder 21 to drive the cup holder 21 to move up and down within the working chamber; and The control circuit board 4 is located outside the inner shell 1. The control circuit board 4 is electrically connected to the drive motor 3 through the wire assembly 5. The upper end of the wire assembly 5 is fixed near the upper end of the wire outlet groove 11, and the lower end of the wire assembly 5 passes through the cup holder 21 and is fixed around the outside of the cup holder 21. As the cup holder 21 rises from the low position to the high position, the wire assembly 5 gradually transitions from an extended and stretched state to an arc-shaped bent state. While the wire assembly 5 is bending and deforming, it can extend to the outside of the inner shell 1 through the wire outlet groove 11.

[0027] In the technical solution of this utility model, the wire assembly 5 led out from the control circuit board 4 is electrically connected to the drive motor 3 to provide an electrical signal to the drive motor 3. During the rising or falling of the cup holder 21, in order to avoid the wire assembly 5 from folding and bending in the narrow space of the working cavity, this solution provides a wire outlet groove 11 extending in the vertical direction on the inner shell 1, and fixes the upper end and lower end of the wire assembly 5 near the upper end of the wire outlet groove 11 and the outside of the cup holder 21, respectively. As the cup holder 21 rises from a low position to a high position, the main body of the wire assembly 5 gradually bends and bulges towards the wire outlet groove 11; as the cup holder 21 falls from a high position to a low position, the main body of the wire assembly 5 tends to straighten. This avoids problems such as breakage and poor contact caused by excessive bending or winding of the wire assembly 5, thus extending the service life of the wire. At the same time, when the wire assembly 5 is in a bent state, the wire assembly 5 can extend to the outside of the inner shell 1 through the wire outlet groove 11, preventing the wire from interfering with the movement of the cup holder 21 in the working cavity and improving safety.

[0028] Specifically, the inner shell 1 can be cylindrical or square, and the cavity wall of the working chamber or the outer wall of the inner shell 1 can be provided with multiple raised ribs to improve the overall strength of the inner shell 1. The cup holder 21 has a hollow cubic structure, forming a square installation space inside, and the drive motor 3 can be fixed to the installation space by bolts. The container assembly 22 serves as a material storage container, used as a material storage structure during the operation of the ice cream machine 100. The control circuit board 4 can be fixed to the external mounting bracket above the inner shell 1 by bolts, and is used to control the overall operation of the entire ice cream machine 100. It is worth noting that the fixing of the upper and lower ends of the wiring assembly 5 can be done by binding with cable ties or by adhesive fixing, and no specific limitation is made here.

[0029] Please see Figure 4The principle of the drive motor 3 driving the cup holder 21 to rise and fall is explained as follows: The drive motor 3 and transmission module 9 are installed within the mounting space of the cup holder 21. The transmission module 9 includes a threaded shaft, a worm gear 91, a drive rod 92, a screw 93, and a sleeve 94. The worm gear 91 is threadedly connected to the threaded shaft, and the cup holder 21 is rotatably connected to the worm gear 91. The drive rod 92 is horizontally positioned within the mounting space, with a screw 93 coaxially mounted at each end. The drive motor 3 is connected to the drive rod 92 via a reducer, causing the drive rod 92 to rotate, which in turn drives the screw 93 to rotate. The screw 93 meshes with the threaded shaft, and as the screw 93 rotates, it drives the worm gear 91 to rotate and rise along the threaded shaft, thereby causing the cup holder 21 and the cup body 221 to rise. The worm gear 91 has a coaxial first wheel portion and a second wheel portion. The first wheel portion has an external thread that is threadedly connected to the screw 93, and the second wheel portion has an internal thread that is threadedly connected to the threaded shaft. The cup holder 21 is rotatably connected to the outer circumference of the second wheel portion via a bearing. Additionally, movable holes 214 can be provided on both sides of the cup holder 21. The sleeve 94 is located in the movable hole 214 and is sleeved on the outer circumference of the second wheel part of the worm gear 91. The bottom of the sleeve 94 is fixedly connected to the first wheel part. The sleeve 94 is connected to the movable hole 214 through a bearing. When the screw 93 rotates, it drives the worm gear 91 to rotate and rise. The sleeve 94 rotates in the movable hole 214 and pushes the cup holder 21 to rise. When the worm gear 91 rotates in the opposite direction and falls, the sleeve 94 drives the cup holder 21 to fall through the bearing, thus completing the connection and separation of the cup holder 21 and the tool assembly 8.

[0030] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 When the cup holder 21 is in its raised position, the wire assembly 5 is in a "U"-shaped bend outside the inner shell 1. This makes the deformation path of the wire assembly 5 smoother and more controllable during the raising and lowering of the cup holder 21. The "U"-shaped structure prevents insulation damage or conductor breakage caused by excessive local bending (such as sharp-angle folding), significantly extending the wire's service life. In one embodiment, the upper and lower ends of the outlet groove 11 can be rounded, and wear-resistant sleeves can be added to the groove wall of the outlet groove 11 to ensure a smooth transition of the wire assembly 5 when entering and exiting the groove, avoiding scratches. Furthermore, symmetrical arc-shaped limiting ribs can be provided on both sides of the outlet groove 11, with the distance between the two limiting ribs slightly larger than the width of the wire after the "U"-shaped bend. When the cup holder 21 rises, the wire assembly 5 is guided by the limiting ribs to naturally form a "U" shape, preventing the bent portion from swaying or deviating from the preset path.

[0031] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The cup holder 21 has a lower cable pass-through port 211, and the top of the inner shell 1 has an upper cable pass-through port 12. The lower end of the wire assembly 5, which is electrically connected to the drive motor 3, passes through the lower cable pass-through port 211 and extends to the outside of the inner shell 1 through the cable outlet groove 11. The upper end of the wire assembly 5, which is electrically connected to the control circuit board 4, passes through the upper cable pass-through port 12 and extends to the outside of the inner shell 1 through the cable outlet groove 11. The lower cable pass-through port 211 can be circular, square, or other irregular shapes. The lower end of the wire assembly 5 is connected to the drive motor 3 through a crimp terminal. After passing through, the gap between the wire assembly 5 and the lower cable pass-through port 211 is filled with waterproof glue (such as silicone glue) to prevent liquid in the working chamber from seeping into the installation space inside the cup holder 21. The upper cable pass-through port 12 can be waist-shaped, "L"-shaped, or "T"-shaped, etc. The edge of the upper cable pass-through port 12 can be provided with an inwardly folded guide edge to guide the wire assembly 5 to smoothly transition from the cable outlet groove 11 to the outside. In addition, the upper end of the wiring assembly 5 is protected by heat shrink tubing, which passes through and is then secured to the top of the inner shell 1 with clips.

[0032] In the embodiments of this utility model, please refer to Figure 5 The inner shell 1 is also provided with an upper wire fixing hole 13, which is located near the top of the cable outlet groove 11. The upper end of the wire assembly 5 is fixed at the upper wire fixing hole 13. The upper wire fixing hole 13 can be a circular through hole, through which cable ties can be used to bind the wire assembly 5. The upper wire fixing hole 13 is located near the top of the cable outlet groove 11 and works in conjunction with the upper wire threading port 12 to form a double fixation for the upper end of the wire assembly 5. The upper wire threading port 12 is used to guide the path, and the upper wire fixing hole 13 is used to lock the position, eliminating the risk of the wire shaking, tangling, or colliding with the inner shell 1 due to the free swing of the upper end during the lifting and lowering of the cup holder 21, and ensuring that the wire always moves along the predetermined path of the cable outlet groove 11.

[0033] In the embodiments of this utility model, please refer to Figure 6 The cup holder 21 is also provided with a lower fixing hole 212, which is located near the lower cable entry port 211. The lower end of the wire assembly 5 is fixed at the lower fixing hole 212. The lower fixing hole 212 can be a threaded hole or a circular through hole, and it is located near the lower cable entry port 211. The wire assembly 5 first passes through the lower cable entry port 211 into the interior of the cup holder 21, and then a cable tie or steel rope is threaded through the lower fixing hole 212 to bind the lower end of the wire assembly 5. The lower cable entry port 211 guides the wire path, and the lower fixing hole 212 locks the position, ensuring that the lower end of the wire assembly 5 does not move axially or radially. For example, when the cup holder 21 is raised or lowered, the part of the wire assembly 5 below the lower fixing hole 212 (connected to the drive motor 3 section) is completely stationary, and only the part above it deforms, avoiding stress on the motor output side.

[0034] In an embodiment of this invention, the ice cream machine 100 further includes a wire wrapping sleeve, which is wound around the outer wall of the wire assembly 5. 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 wire assembly 5 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.

[0035] In the embodiments of this utility model, please refer to Figure 1 The ice cream machine 100 also includes a housing 6, which encloses the inner housing 1. A receiving space is formed between the inner wall of the housing 6 and the outer wall of the inner housing 1. The control circuit board 4 is located within this receiving space, and the wiring assembly 5 extends into the receiving space through the cable outlet 11. Specifically, the housing 6, as an external support component of the ice cream machine 100, can be made of metal or plastic, without limitation. The housing 6 can be square or round, without limitation. Furthermore, the receiving space between the housing 6 and the inner housing 1 allows the wiring assembly 5 to extend out, preventing it from being folded or bent within the working cavity and shortening its service life. A support pad, made of silicone, can be provided at the bottom of the housing 6. This not only increases the friction between the housing 6 and supports such as tabletops, preventing movement when grinding ice cubes inside the working cavity, but also reduces shaking during grinding or stirring. By enclosing the inner housing 1 with the housing 6, the drive motor 3 and control circuit board 4 within the working cavity are protected, ensuring the normal operation of stirring or grinding.

[0036] In the embodiments of this utility model, please refer to Figure 3 , Figure 7 and Figure 8 The ice cream machine 100 also includes a rotating shaft 7 and a blade assembly 8. The rotating shaft 7 is rotatably located at the top of the working chamber. The blade assembly 8 is installed at the end of the container assembly 22 near the rotating shaft 7. The blade assembly 8 moves synchronously with the container assembly 22, approaching or moving away from the rotating shaft 7. When the container assembly 22 rises, the blade assembly 8 moves closer to the rotating shaft 7 until it engages with the rotating shaft 7, ensuring the stability of power transmission. When the container assembly 22 falls, the blade assembly 8 moves away from the rotating shaft 7, facilitating the removal and cleaning of the container assembly 22. As a refrigeration device, when the blade assembly 8 on the container assembly 22 is assembled with the rotating shaft 7, the blade assembly 8 can fully grind the ice cubes in the container assembly 22 into shaved ice under the drive of the rotating shaft 7. It is worth noting that the bottom outer wall of the rotating shaft 7 may be provided with a spiral or inclined mounting key. Correspondingly, the top of the blade assembly 8 may be provided with a keyway of a corresponding shape. The two are automatically engaged and disengaged through the lifting and lowering of the container assembly 22.

[0037] In the embodiments of this utility model, please refer to Figure 7 The container assembly 22 includes a cup body 221 and a cup lid 222. The cup lid 222 is detachably mounted on the mouth of the cup body 221. A blade assembly 8 is mounted on the cup lid 222. The cup body 221 is detachably mounted on a cup holder 21. The cup holder 21 drives the cup body 221 to move up or down within the working chamber. In this embodiment, the blade assembly 8 is positioned above the cup holder 21. The cup body 221 is located on the top of the cup holder 21, and the cup mouth is located on the top of the cup body 221. The cup lid 222 is located at the mouth. Ice cubes or other food to be processed are placed inside the cup body 221. The cup holder 21 moves toward the blade assembly 8, allowing the blade assembly 8 to pass through the cup lid 222 and grind the ice cubes inside the cup body 221 through rotation. The detachable connection of the cup body 221 allows it to be removed separately from the cup holder 21. Users can easily perform operations such as changing to cup bodies 221 of different capacities, cleaning the cup lid 222, or changing the blade assembly 8 according to different needs. The connection between the cup body 221 and the cup base 21 can be achieved by using a limiting fit of protrusions and grooves, or by using a magnetic attraction method to achieve quick assembly and disassembly.

[0038] In the embodiments of this utility model, please refer to Figure 6 and Figure 9 A limiting protrusion 213 is provided on one of the inner wall of the cup holder 21 and the outer wall of the cup body 221, and a limiting groove 2211 is provided on the other of the inner wall of the cup holder 21 and the outer wall of the cup body 221, with the limiting protrusion 213 cooperating with the limiting groove 2211. The limiting protrusion 213 can be an arc-shaped strip, and multiple such protrusions are provided at intervals on the cup holder 21 or the cup body 221. Correspondingly, the limiting groove 2211 has the same shape as the limiting protrusion 213, and the number of limiting grooves 2211 and limiting protrusions 213 is equal, for example, three of each, forming a "three-point positioning" structure to restrict the radial movement and axial rotation of the cup body 221.

[0039] In the embodiments of this utility model, please refer to Figure 8 and Figure 9 A rotating buckle 2221 is provided on one of the inner wall of the lid 222 and the outer wall of the cup body 221, and a rotating groove 2212 is provided on the other of the inner wall of the lid 222 and the outer wall of the cup body 221. When the lid 222 is placed on the mouth of the cup body 221, the rotating buckle 2221 engages with the rotating groove 2212. The rotating buckle 2221 can be L-shaped, and the end of the horizontal section is provided with a guide slope (e.g., at an angle of 15°) to facilitate insertion into the rotating groove 2212. A flared guide groove can be provided at the entrance of the rotating groove 2212 to guide the rotating buckle 2221 into place quickly; a locking buckle can also be provided at the end of the rotating groove 2212, which locks the rotating buckle 2221 in place after it has been rotated into position, effectively preventing the lid 222 from loosening due to vibration or causing material leakage during stirring.

[0040] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection 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 scope of protection of the present utility model.
