DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] Please also see Figure 1-Figure 14 , the present invention provides some embodiments of an ice cream machine.

[0034] like Figure 1-Figure 2 As shown, the ice cream machine of the present invention comprises: a base 10 , a container 20 and a stirrer 30 .

[0035] Specifically, the ice cream machine can prepare ice cream based on ice cream raw materials, the container 20 is used to load and contain the ice cream raw materials, and the stirrer 30 is used to crush and stir the ice cream raw materials to prepare ice cream. The ice cream machine may also include: an extruder 40, the extruder 40 is used to squeeze the ice cream, and multiple portions of ice cream may be squeezed out in portions. The ice cream raw materials may include ice cubes, milk, milk powder, cream, edible sugar, salt, additives, etc.

[0036] In a preferred implementation of the embodiment of the present invention, Figure 2-Figure 3 As shown, the container 20 comprises: The receiving tube 21 is disposed on the base 10; A cover body 22, disposed on the accommodating tube 21; An elastic clamp 23 is disposed on the inner side of the cover body 22; The tool 24 is clamped by the elastic clamp 23 .

[0037] Specifically, the accommodating cylinder 21 can accommodate ice cream raw materials, and the cover 22 is detachably connected to the accommodating cylinder 21. After the cover 22 is opened, the ice cream raw materials are placed in the accommodating cylinder 21, and then the cover 22 is closed, and the ice cream raw materials can be crushed and stirred by the stirrer 30. The cutter 24 is located in the accommodating cylinder 21 and is clamped by the elastic clamp 23. The elastic clamp 23 clamps the cutter 24 by elastic force, and the cutter 24 can also overcome the elastic force of the elastic clamp 23 and detach from the elastic clamp 23.

[0038] In a preferred implementation of the embodiment of the present invention, Figure 2 As shown, the stirrer 30 comprises: A chassis 31, disposed on the base 10; The lifting mechanism 32 and the rotating mechanism 33 are both arranged on the chassis 31; The connecting shaft 34 is connected to the lifting mechanism 32 and the rotating mechanism 33 respectively.

[0039] Specifically, the lifting mechanism 32 and the rotating mechanism 33 are both located in the housing 31, and the connecting shaft 34 is detachably connected to the cutter 24. The lifting mechanism 32 is used to drive the connecting shaft 34 to lift and lower, thereby driving the cutter 24 to lift and lower. The rotating mechanism 33 is used to drive the connecting shaft 34 to rotate, thereby driving the cutter 24 to rotate. The lifting and rotating of the cutter 24 is used to crush and stir the ice cream raw materials.

[0040] In a preferred implementation of the embodiment of the present invention, Figure 3 and Figure 5 As shown, during the descent of the connecting shaft 34 , after the connecting shaft 34 is connected to the tool 24 , the tool 24 is separated from the elastic clamp 23 ; during the ascending process of the connecting shaft 34 , after the tool 24 is clamped by the elastic clamp 23 , the tool 24 is separated from the connecting shaft 34 .

[0041] Specifically, after the connecting shaft 34 is connected to the cutter 24, the connecting shaft 34 is lowered by the lifting mechanism 32, which can drive the cutter 24 to descend and break through the elastic force of the elastic clamp 23, so that the cutter 24 is separated from the elastic clamp 23, and the cutter 24 can contact the ice cream raw material. When the preparation of ice cream is stopped, the connecting shaft 34 is raised by the lifting mechanism 32, which can drive the cutter 24 to rise and break through the elastic force of the elastic clamp 23, so that the cutter 24 is clamped by the elastic clamp 23, and the connecting shaft 34 and the cutter 24 can be separated.

[0042] In the present application, the connection between the elastic clamp 23 and the cutter 24 is more flexible. By lifting the connecting shaft 34 and the cutter 24 by the lifting mechanism 32, the clamping and separation of the elastic clamp 23 and the cutter 24 can be realized. The connection and separation of the elastic clamp 23 and the cutter 24, and the connection and separation of the connecting shaft 34 and the cutter 24 can be flexibly arranged according to the needs to adapt to more application scenarios. For example, the sequence can be flexibly arranged. After loading the ice cream raw materials, the cover body 22 is covered on the accommodating cylinder 21. At this time, the cutter 24 is connected to the elastic clamp 23, and the cutter 24 is not connected to the connecting shaft 34. Then, the cutter 24 needs to be connected to the connecting shaft 34. The container 20 and the cutter 24 can be moved upward to realize the connection between the cutter 24 and the connecting shaft 34, or the connecting shaft 34 can be lowered by the lifting mechanism 32 to realize the connection between the cutter 24 and the connecting shaft 34. When the preparation of ice cream is stopped, the container 20 and the cutter 24 can be moved downward to separate the cutter 24 from the connecting shaft 34 , or the connecting shaft 34 can be raised by the lifting mechanism 32 to separate the cutter 24 from the connecting shaft 34 .

[0043] A thread structure 341 is formed at the end of the connecting shaft 34, and a thread groove 2411 is formed on the cutter 24. The thread groove 2411 cooperates with the thread structure 341 to realize the connection between the connecting shaft 34 and the cutter 24. The extending direction of the thread structure 341 from bottom to top is opposite to the rotation direction of the rotating mechanism 33 when preparing ice cream. When the connecting shaft 34 rotates, the cutter 24 and the connecting shaft 34 are more tightly connected and are not easy to be separated. For example, from a top view, the thread structure 341 extends from bottom to top in a clockwise direction, and the rotation direction of the rotating mechanism 33 when preparing ice cream is counterclockwise. The cutter 24 can be made of steel or iron material, and the end of the connecting shaft 34 can also be embedded with a permanent magnet 342, which is beneficial to the connection between the cutter 24 and the connecting shaft 34.

[0044] In a preferred implementation of the embodiment of the present invention, Figure 4-Figure 5 As shown, the tool 24 includes: A connector 241, configured to connect the connecting shaft 34; A plurality of blades 242 are disposed on the connecting head 241; A guide protruding ring 243 is provided at an end of the connecting head 241 away from the blade 242; The guide protrusion ring 243 is formed with an upper guide surface 2431 and a lower guide surface 2432 .

[0045] Specifically, a thread groove 2411 is formed on the connector 241, and is threadedly connected to the thread structure 341 at the end of the connecting shaft 34. The notch of the thread groove 2411 is located at the top of the connector 241, and the blade 242 is arranged at the bottom of the connector 241, away from the notch of the thread groove 2411. The blade 242 includes: a cutting blade 242 and a stirring blade, the cutting blade 242 is used for cutting and crushing, and the stirring blade is used for stirring. The guide convex ring 243 is located at one end of the connector 241 away from the blade 242, and the guide convex ring 243 is close to the thread groove 2411. The guide convex ring 243 has two guide surfaces, namely an upper guide surface 2431 and a lower guide surface 2432, the upper guide surface 2431 is away from the blade 242, and the lower guide surface 2432 is toward the blade 242. The cross section of the guide convex ring 243 is triangular or trapezoidal, the two sides of the triangle are the upper guide surface 2431 and the lower guide surface 2432, and the two sides of the trapezoid are the upper guide surface 2431 and the lower guide surface 2432. The two guide surfaces of the guide convex ring 243 guide the elastic clamp 23. During the separation process of the cutter 24 and the elastic clamp 23, the cutter 24 and the container 20 move away from each other, and under the guidance of the lower guide surface 2432, the elastic clamp 23 moves and opens, and the cutter 24 is separated from the elastic clamp 23; during the connection process of the cutter 24 and the elastic clamp 23, the cutter 24 and the container 20 move closer to each other, and under the guidance of the upper guide surface 2431, the elastic clamp 23 moves and opens, and the cutter 24 is connected to the elastic clamp 23.

[0046] The connector 241 is further formed with a reinforcing ring 244, which is close to the blade 242, and a first distance is formed between the reinforcing ring 244 and the guide protruding ring 243, and a guide surface is formed on one side of the reinforcing ring 244 facing the guide protruding ring 243. The reinforcing ring 244 is conducive to enhancing the structural strength of the cutter 24.

[0047] In a preferred implementation of the embodiment of the present invention, Figure 5-Figure 6 As shown, the cover body 22 is provided with a through hole 221 , and the through hole 221 is for the connecting shaft 34 to pass through.

[0048] Specifically, the cover body 22 and the accommodating cylinder 21 are connected to form an accommodating space, and the elastic clamp 23 is located on the inner side of the cover body 22, that is, in the accommodating space. A through hole 221 is formed on the cover body 22 for the connecting shaft 34 to pass through. The connecting shaft 34 passes through the through hole 221 from the outer side of the cover body 22 to the inner side of the cover body 22 and is connected to the tool 24. The connecting shaft 34 can rotate in the through hole 221.

[0049] In a preferred implementation of the embodiment of the present invention, Figure 5-Figure 8 As shown, the elastic clamp 23 includes: A mounting seat 231 connected to the cover body 22, wherein the mounting seat 231 is formed with a tube structure 2311, which is arranged around the through hole 221, and a pin hole 2312 is formed on the tube structure 2311; A plurality of sliding members 232 are slidably disposed on the mounting seat 231 , and ends of the sliding members 232 pass through the pin holes 2312 and abut against the connector 241 ; The toggle member 233 is sleeved outside the tube structure 2311; An elastic member 234, two ends of which are respectively connected to the toggle member 233 and the mounting seat 231; When the toggle member 233 rotates, the sliding member 232 is driven to slide.

[0050] Specifically, the mounting seat 231 is used to mount the sliding member 232, the toggle member 233 and the elastic member 234. The mounting seat 231 is connected to the cover body 22, and an installation space is formed between the mounting seat 231 and the cover body 22, and the sliding member 232, the toggle member 233 and the elastic member 234 are all located in the installation space. The sliding track of the sliding member 232 can be a straight track, and the end of the sliding member 232 forms a latch 2323, which passes through the pin hole 2312 and abuts against the connector 241. The clamping of the ends of the multiple sliding members 232 on the connector 241 can be the supporting force of the ends of the sliding members 232 on the guide convex ring 243, so as to realize the connection between the tool 24 and the elastic clamp 23. When the sliding member 232 slides close to the connector 241, the sliding member 232 clamps the connector 241; when the sliding member 232 slides away from the connector 241, the sliding member 232 releases the connector 241. The toggle member 233 is used to toggle the sliding member 232 so that the sliding member 232 slides in a direction away from the connector 241, and the elastic clamp 23 releases the cutter 24. The elastic member 234 provides an elastic force to move the toggle member 233 and drive the sliding member 232 to slide in a direction close to the connector 241. Under the elastic force of the elastic member 234, each sliding member 232 remains close to each other. When the connector 241 is located between multiple sliding members 232, the cutter 24 is clamped by the elastic clamp 23, and the elastic force of the elastic member 234 is overcome, so that the connector 241 can be separated from the multiple sliding members 232; when the connector 241 is located outside the multiple sliding members 232, the cutter 24 is not clamped by the elastic clamp 23, and the elastic force of the elastic member 234 is overcome, so that the connector 241 can be supported by the multiple sliding members 232.

[0051] The toggle member 233 includes: The ring portion 2331 is sleeved outside the tube structure 2311, and a plurality of sliding holes 2332 are formed on the ring portion 2331; The expansion portion 2333 is disposed on the ring portion 2331 .

[0052] Specifically, the ring portion 2331 can rotate relative to the barrel structure 2311. The proximal end of the sliding hole 2332 is close to the center ring of the ring portion 2331, and the sliding distal end is far away from the center ring of the ring portion 2331.

[0053] The mounting seat 231 is provided with a guide bar 2314. The sliding member 232 includes: The main body 2321 forms a guide groove 2322; The latch 2323 is disposed at one end of the main body 2321 facing the connector 241; A column 2324 is disposed at one end of the main body 2321 facing the toggle member 233; The latch pin 2323 passes through the pin hole 2312 and abuts against the annular protrusion; the column 2324 is inserted into the sliding hole 2332 ; and the guide bar 2314 is located in the guide groove 2322 .

[0054] Specifically, the guide strip 2314 is arranged along the radial direction of the cylinder structure 2311, and the main body 2321 slides along the guide strip 2314, driving the latch 2323 to approach the connector 241 and to move away from the connector 241. When the main body 2321 slides along the guide strip 2314, the column 2324 is restricted from sliding, and the sliding member 232, the toggle member 233 and the elastic member 234 form a linkage structure. When the toggle member 233 rotates, the main body 2321 is driven to move along the guide strip 2314 through the column 2324, and the elastic member 234 is extended and retracted. The elastic member 234 can be a spring. For example, from a top view, when the toggle member 233 rotates clockwise relative to the cover body 22, the spring is stretched, the column 2324 slides from the proximal end of the sliding hole 2332 toward the distal end of the sliding hole 2332, the latch 2323 moves away from the connector 241, the elastic clamp 23 is in a loose state, and the elastic clamp 23 can be separated from the cutter 24. When the toggle member 233 rotates counterclockwise relative to the cover body 22, the spring recovers its deformation, the column 2324 slides from the distal end of the sliding hole 2332 to the proximal end of the sliding hole 2332, the pin 2323 approaches the connector 241, the elastic clamp 23 is in a clamped state, and the elastic clamp 23 can be connected to the tool 24.

[0055] The chassis 31 is provided with a stopper 311, which is used to block the expansion part 2333. When the accommodating cylinder 21 and the cover body 22 rotate relative to the chassis 31, the expansion part 2333 is blocked by the stopper 311, and the toggle member 233 stops rotating relative to the chassis 31, and then the toggle member 233 and the cover body 22 rotate relative to each other, thereby adjusting the clamping state and the loosening state of the elastic clamp 23. For example, from a top view, when the accommodating cylinder 21 and the cover body 22 rotate counterclockwise relative to the chassis 31, the expansion part 2333 is blocked by the stopper 311, and the accommodating cylinder 21 and the cover body 22 continue to rotate counterclockwise, and the toggle member 233 stops rotating, then the toggle member 233 rotates clockwise relative to the cover body 22, and the elastic clamp 23 is in a loosened state. When the accommodating cylinder 21 and the cover body 22 rotate clockwise relative to the chassis 31, the expansion portion 2333 maintains contact with the stop block 311, and the accommodating cylinder 21 and the cover body 22 continue to rotate clockwise, and the toggle member 233 does not rotate. Then, the toggle member 233 rotates counterclockwise relative to the cover body 22, and the elastic clamp 23 is in a clamped state.

[0056] In a preferred implementation of the embodiment of the present invention, Figure 5 As shown, a limit ring 2313 is provided on the inner side of the cylinder structure 2311 , and a seal 25 is provided between the limit ring 2313 and the cover body 22 .

[0057] Specifically, a limiting ring 2313 is provided inside the cylinder structure 2311, and the limiting ring 2313 limits the connector 241. When the connector 241 moves upward, the connector 241 is limited by the limiting ring 2313 and cannot move outside the cylinder structure 2311. A sealing member 25 is provided between the limiting ring 2313 and the cover 22, and a sealing ring is provided between the edge of the mounting seat 231 and the cover 22, so that the sealing of the mounting space formed by the mounting seat 231 and the cover 22 can be improved.

[0058] In a preferred implementation of the embodiment of the present invention, Figure 5 As shown, the sealing member 25 comprises: The tapered portion 251 surrounds the connecting shaft 34; The connecting portion 252 is disposed outside the conical portion 251 and is clamped between the limiting ring 2313 and the cover body 22; The extending portion 253 is disposed on the connecting portion 252 and extends toward the connecting head 241 .

[0059] Specifically, the seal 25 can also seal between the connecting shaft 34 and the cylinder structure 2311. The connecting portion 252 is clamped between the limiting ring 2313 and the cover body 22, and seals between the mounting seat 231 and the cover body 22. The conical portion 251 is a conical structure with a larger upper portion and a smaller lower portion, and the conical portion 251 seals between the connecting shaft 34 and the cylinder structure 2311. The extension portion 253 extends between the annular protrusion and the limiting ring 2313. When the connector 241 moves upward, it contacts the extension portion 253. Through the buffering of the extension portion 253, the connector 241 will not damage the limiting ring 2313.

[0060] In a preferred implementation of the embodiment of the present invention, Figure 3 , Fig. 9 as well as Fig.10 As shown, a positioner 35 is disposed on the chassis 31 , and the positioner 35 is used to detect whether the container 20 is located at a preset position.

[0061] Specifically, the preset position is a position where the connecting shaft 34 is at the initial position, the cutter 24 is connected to the connecting shaft 34, and the elastic clamp 23 is in a loose state. The positioner 35 is used to detect whether the container 20 is at the preset position. For example, when the container 20 is at the preset position, it indicates that the cutter 24 is connected to the connecting shaft 34, and the elastic clamp 23 is in a loose state. The rotating mechanism 33 can be controlled to rotate the connecting shaft 34 and the cutter 24, and the lifting mechanism 32 can be controlled to lift the connecting shaft 34 and the cutter 24. When the container 20 is at the preset position, the container 20 is clamped between the rotating lifting seat 12 and the chassis 31, and the stability of the container 20 is higher.

[0062] The cover body 22 is provided with a push pin 222; the positioner 35 includes: The sensor 351 is disposed on the chassis 31; The elastic pressing member 352 is slidably disposed on the chassis 31; When the cover 22 rotates, the push pin 222 pushes the elastic pressing member 352 to slide and press the sensor 351 .

[0063] Specifically, from a top view, when the cover 22 rotates counterclockwise, the push pin 222 rotates counterclockwise, and the push pin 222 abuts against and pushes the elastic pressing member 352, so that the elastic pressing member 352 presses the sensor 351. In this process, since the toggle member 233 rotates clockwise relative to the cover 22, the elastic clamp 23 is in a loose state, that is, when the elastic pressing member 352 presses the sensor 351, the elastic clamp 23 is in a loose state, indicating that the container 20 is located at the preset position.

[0064] The elastic pressing piece 352 forms a chamfer on one side facing the sensor 351, and the pushing pin 222 adopts an elastic pushing pin 222. When the elastic pushing pin 222 rotates clockwise against the elastic pressing piece 352, the elastic pushing pin 222 contacts the chamfer and moves downward, and the elastic pressing piece 352 and the elastic pushing pin 222 do not interfere with each other.

[0066] Specifically, the rotary lifting seat 12 is lifted and lowered relative to the fixed seat 11, and the rotary lifting seat 12 lifts and rotates the container 20 to facilitate the connection between the connecting shaft 34 and the tool 24. In addition, during the rotation process, the toggle member 233 is restricted by the block 311, so that the elastic clamp 23 is in a loose state; the pushing pin 222 pushes the elastic pressing member 352 to press the sensor 351.

[0068] Specifically, after the lifting cover 121 is connected to the accommodating tube 21, the accommodating tube 21 is rotated, and the lifting cover 121 rotates and rises accordingly. The block 122 and the elastic pin 123 realize the connection between the accommodating tube 21 and the lifting cover 121, and the accommodating tube 21 and the lifting cover 121 rotate synchronously. The bottom of the accommodating tube 21 is provided with a plurality of slots and at least one pin slot, the slots are engaged with the block 122, and the elastic pin 123 is inserted into the pin slot.

The elastic pin 123 can also be configured on other sides of the lifting cover 121. During the process of inserting the accommodating cylinder 21 from the front side of the lifting cover 121, the block 122 on the left side and the block 122 on the right side are respectively engaged with the corresponding slots, and the elastic pin 123 is compressed; when the accommodating cylinder 21 continues to be inserted, the block 122 on the rear side is engaged with the corresponding slot, and the elastic pin 123 restores its deformation and is inserted into the pin slot at the bottom of the accommodating cylinder 21.

[0069] A sleeve 1211 is disposed on the inner side of the lifting cover 121, a sliding rod 1212 is disposed on the bottom of the sleeve 1211, and the fixing seat 11 includes: The seat body 111 is formed with a receiving groove 112; The spiral groove structure 113 is disposed in the receiving groove 112; A guide post 114 is disposed in the receiving groove 112; The guide column 114 is inserted into the sleeve 1211 , and the sliding rod 1212 is inserted into the spiral groove structure 113 .

[0070] Specifically, when the lifting cover 121 is rotated, the guide column 114 slides in the sleeve 1211. The slide bar 1212 slides in the spiral groove structure 113, and the spiral groove structure 113 includes a spiral portion 1131 and a platform portion 1132. When the slide bar 1212 is located at the platform portion 1132, the lifting cover 121 can be stably maintained at a higher position. When the slide bar 1212 is in the spiral portion 1131, the lifting cover 121 can be lifted and rotated.

[0071] In a preferred implementation of the embodiment of the present invention, Figure 2-Figure 4 As shown, the accommodating tube 21 includes: outer cylinder 211; The inner cylinder 212 is located inside the outer cylinder 211; Wherein, an outlet plug 213 is provided at the bottom of the inner cylinder 212 .

[0072] Specifically, the receiving cylinder 21 has two layers of cylinders, which is conducive to maintaining the temperature in the inner cylinder 212. An outlet plug 213 is provided at the bottom of the inner cylinder 212. After the outlet plug 213 is opened, the ice cream in the inner cylinder 212 can be squeezed out. The outer cylinder 211 is connected to the cover body 22. A handle is provided on the outer cylinder 211 for easy holding. Holding the handle can connect the receiving cylinder 21 to the rotating lifting seat 12, and it is also convenient to rotate the receiving cylinder 21.

[0074] Specifically, after the ice cream in the inner cylinder 212 is prepared, the cover 22 can be opened, and the inner cylinder 212 loaded with ice cream can be taken out and assembled to the squeezer 40 , and then the squeezer 40 can be controlled to squeeze the ice cream inside the inner cylinder 212 .

[0075] Based on the ice cream machine described in any of the above embodiments, the present invention also provides a preferred embodiment of an ice cream preparation method based on the ice cream machine: The ice cream preparation method based on the ice cream machine of the embodiment of the present invention comprises the following steps: Step S100, connecting the coupling shaft and the cutter; wherein the connection method of the coupling shaft and the cutter includes: a connection method of lowering the coupling shaft, and a connection method of moving the container upward; Step S200, controlling the rotation of the cutter by the rotating mechanism and controlling the lifting and lowering of the cutter by the lifting mechanism to make ice cream; Step S300, when stopping making ice cream, the lifting mechanism is used to control the connecting shaft to rise and connect the cutter and the elastic clamp, and then the rotating mechanism is used to control the connecting shaft to stop rotating, and the connecting shaft and the cutter are separated; wherein the separation method of the connecting shaft and the cutter includes: a separation method of raising the connecting shaft, and a separation method of moving the container downward.

[0076] Specifically, when preparing ice cream, the container is removed and opened, and the ice cream raw materials are placed in the container and then the container is closed. Then the coupling and the cutter are connected. There are two ways to connect the coupling and the cutter. One is to lower the coupling to achieve the connection between the coupling and the cutter, and the other is to raise the container to achieve the connection between the coupling and the cutter. For example, the coupling can be controlled to be lowered by a lifting mechanism, or the container can be raised by rotating the lifting seat. After the coupling and the cutter are connected, the coupling and the cutter can be rotated by a rotating mechanism, and the coupling and the cutter can be raised by the lifting mechanism, and the ice cream raw materials can be crushed and stirred by the cutter to form ice cream. When the production of ice cream stops, the coupling and the cutter are controlled to rise by the lifting mechanism, so that after the cutter is connected to the elastic clamp, the coupling is controlled to stop rotating by the rotating mechanism, and then the coupling and the cutter are separated. There are two ways to separate the coupling and the cutter. One is to raise the coupling to achieve the separation of the coupling and the cutter, and the other is to lower the container to achieve the separation of the coupling and the cutter.

[0077] Since there are many ways to connect and separate the coupling and the cutter, the preparation process and application scenarios are more diverse. For example, the connection and separation of the lifting coupling can save the manual assembly process, shorten the ice cream preparation time, and make it convenient to open the container to view the ice cream preparation effect, which is especially suitable for exploring the preparation parameters of new ice cream ingredients. The connection and separation of the lifting container makes the container assembly more secure, which is conducive to increasing the service life of the ice cream machine.

[0078] The ice cream preparation method also includes: Step S400: After the inner cylinder is connected to the squeezer, the squeezer is controlled to squeeze the ice cream in the inner cylinder so that the ice cream flows out.

[0079] Specifically, after the ice cream is prepared, the inner cylinder containing the ice cream can be removed, and the inner cylinder is assembled on an extruder, and the ice cream in the inner cylinder is squeezed out by the extruder according to the portion.

[0080] When the coupling and the tool are connected by a connection method of moving the container upward, the positioner detects that the container is located at a preset position; when the positioner detects that the container is not located at the preset position, the coupling and the tool are connected by a connection method of lowering the coupling; when the positioner detects that the container is located at the preset position, the coupling and the tool are separated by a separation method of moving the container downward; when the positioner detects that the container is not located at the preset position, the coupling and the tool are separated by a separation method of raising the coupling.

[0081] Specifically, when the container is raised to the preset position, the container can be detected by the positioner, indicating that the coupling is connected to the tool and the elastic clamp is in a loose state. When the container is lowered from the preset position, the container cannot be detected by the positioner, indicating that the elastic clamp is in a clamped state. Although the elastic clamp is in a clamped state, the tool may not be clamped by the elastic clamp. For example, the tool is connected to the coupling, and the tool is lowered to disengage from the elastic clamp and rotate. Even if the container is lowered, the tool may still be not clamped by the elastic clamp, and the tool may still be connected to the coupling and continue to rotate and lift. The coupling and the tool can also be separated by lifting the coupling. Since the container is lowered in advance, the coupling has not been raised to return to the initial position. As long as the coupling is separated from the through hole of the cover body, the container can be removed. At this time, the coupling may still be raised upward, thereby saving time.

[0082] Step S100 specifically includes: Step S110: When the positioner does not detect that the container is located at the preset position, the lifting mechanism controls the coupling to be lowered to the connection position at the assembly lowering speed to achieve the connection between the coupling and the tool.

[0083] Specifically, when the locator detects that the container is located at the preset position, it indicates that the coupling and the tool are already connected. When the locator does not detect that the container is located at the preset position, it indicates that there is a certain distance between the coupling and the container, and the coupling needs to be lowered to the connection position to connect the coupling and the tool. In the process of connecting the coupling and the tool, the coupling can be controlled to rotate at the assembly speed by the rotating mechanism, which is conducive to the connection of the coupling and the tool. The connection position is related to the distance between the coupling and the container and can be pre-configured. In step S200, the rotation speed of the tool is the working rotation speed, and the lifting speed of the tool is the working lifting speed. The working rotation speed is usually greater than the assembly rotation speed, and the working lifting speed is greater than the working lowering speed.

[0084] Step S300 specifically includes: Step S310, when the making of ice cream is stopped and the positioner detects that the container is at a preset position, the connecting shaft is controlled to rise to the initial position by the lifting mechanism, and then the connecting shaft is controlled to stop rotating by the rotating mechanism, and then the container is moved downward to separate the connecting shaft and the cutter; Step S320, when the making of ice cream stops and the positioner does not detect that the container is at the preset position, the connecting shaft is controlled to rise to the connection position by the lifting mechanism, and then the connecting shaft is controlled to stop rotating by the rotating mechanism, and then the connecting shaft is controlled to rise to the initial position by the lifting mechanism to separate the connecting shaft and the cutter.

[0085] Specifically, when the ice cream making process is stopped, the container can be moved downward first, and then the connecting shaft can be controlled to rise by the lifting mechanism and the connecting shaft can be controlled to stop rotating by the rotating mechanism, or the connecting shaft can be controlled to rise by the lifting mechanism and the connecting shaft can be controlled to stop rotating by the rotating mechanism, and then the container can be moved downward. Due to the different positions of the containers, the steps are also different.

[0086] The positioner can be used to determine whether the container is located at the preset position. If the container is located at the preset position and the container is located at a higher position, the lifting mechanism will raise the coupling to the initial position, stop the coupling from rotating, and then move the container downward, so that the coupling is separated from the tool. If the container is not located at the preset position and the container is located at a lower position, the lifting mechanism will raise the coupling to the connection position, stop the coupling from rotating, and then raise the coupling to the initial position. When the coupling is at the connection position, the coupling rises, and the tool is blocked and does not rise with it, thereby separating the coupling from the tool. If the coupling does not rise to the initial position, the container can be removed and opened, which shortens the time.

[0087] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
