DETAILED DESCRIPTION

[0079] 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.

[0080] Please also see Figure 1-Figure 19 , the present invention provides some embodiments of an ice cream machine.

[0081] like Figure 1-Figure 3 As shown, the ice cream machine of the present invention comprises: a base 10, a case 20, a accommodating cylinder 30 and an extruding device 40; the case 20 is arranged on the base 10; the extruding device 40 is arranged on the case 20, and the extruding device 40 is used to squeeze the ice cream in the accommodating cylinder 30. The extruding device 40 can be located at a higher position of the case 20 so that the squeezed ice cream can be received by a container.

[0082] An opening structure 21 is formed on the chassis 20, and a through hole 31 is formed at the bottom of the accommodating cylinder 30. The cylinder mouth of the accommodating cylinder 30 can be assembled on the opening structure 21, and the through hole 31 can allow ice cream to pass through. After the accommodating cylinder 30 loaded with ice cream is assembled on the opening structure 21, the ice cream in the accommodating cylinder 30 is squeezed by the squeezing device 40, and the ice cream is squeezed out of the through hole 31.

[0083] The extrusion device 40 comprises:

[0084] A first driving mechanism 41 is disposed on the chassis 20;

[0085] A first piston structure 42, disposed on the first driving mechanism 41 and located in the opening structure 21;

[0086] Among them, the first piston structure 42 is used to squeeze the ice cream in the accommodating cylinder 30; a locking structure 50 is provided in the opening structure 21, and the opening structure 21 and the locking structure 50 are both detachably connected to the accommodating cylinder 30, and the locking structure 50 rotates relative to the opening structure 21 to lock or release the first piston structure 42.

[0087] Specifically, Figure 1 and Figure 2 As shown, the corresponding position of the first piston structure 42 on the chassis 20 forms an opening structure 21, the first piston structure 42 is located in the opening structure 21, and can be moved to the outside of the opening structure 21 and enter the accommodating cylinder 30, and the opening structure 21 and the accommodating cylinder 30 are detachably connected. A protective cover 22 can be configured at the opening structure 21. When the opening structure 21 is not connected to the accommodating cylinder 30 but connected to the protective cover 22, the first piston structure 42 is protected by the protective cover 22. When the accommodating cylinder 30 is assembled at the opening structure 21, the protective cover 22 at the opening structure 21 can be removed first, and then the accommodating cylinder 30 is assembled. When the accommodating cylinder 30 loaded with ice cream is connected to the opening structure 21 on the chassis 20. The first driving mechanism 41 is used to push the first piston structure 42 into the accommodating cylinder 30, and the ice cream in the accommodating cylinder 30 is squeezed out from the through hole 31.

[0088] The accommodating cylinder 30 may be a circular cylinder, and the first piston structure 42 may slide in the accommodating cylinder 30, and the first piston structure 42 is sealed with the side wall of the accommodating cylinder 30, so that the ice cream in the accommodating cylinder 30 can only be discharged from the through hole 31. The first piston structure 42 may move to the bottom of the accommodating cylinder 30, and the surface of the first piston structure 42 cooperates with the bottom of the accommodating cylinder 30, and the gap between the two is small, so that as much ice cream as possible can be discharged.

[0089] A locking structure 50 is also provided in the opening structure 21, and the locking structure 50 is detachably connected to the accommodating cylinder 30. When the accommodating cylinder 30 is assembled to the opening structure 21, the accommodating cylinder 30 is connected to the locking structure 50, and the locking structure 50 can be driven to rotate by rotating the accommodating cylinder 30, thereby locking the first piston structure 42; when the accommodating cylinder 30 is removed from the opening structure 21, the accommodating cylinder 30 is rotated in the opposite direction to drive the locking structure 50 to rotate in the opposite direction, thereby releasing the first piston structure 42. The present application locks the first piston structure 42 by the locking structure 50, which is beneficial to prevent the first piston structure 42 from moving outside the opening structure 21 and being damaged when the accommodating cylinder 30 is not assembled.

[0090] In a preferred implementation of the embodiment of the present invention, Figure 4 , Figure 5 as well as Figure 6 , the first driving mechanism 41 comprises:

[0091] A driving driver 411 is disposed on the chassis 20;

[0092] A first transmission assembly 412 connected to the output shaft of the push driver 411;

[0093] A lead screw 413 connected to the first transmission assembly 412;

[0094] The push rod 414 is connected to the lead screw 413 .

[0095] Specifically, the first driving mechanism 41 is used to drive the push rod 414 to move, specifically by driving the driver 411 to drive the screw of the lead screw 413 to rotate, and converting it into movement of the nut of the lead screw 413 to push the push rod 414 to move. The first transmission assembly 412 can be a gear transmission assembly.

[0096] In a preferred implementation of the embodiment of the present invention, Figure 5 , Figure 8 as well as Fig. 9 As shown, a groove 4141 is formed on the end surface of the push rod 414 of the first driving mechanism 41 .

[0097] Specifically, the first driving mechanism 41 has a push rod 414 for pushing the first piston structure 42. The end surface of the push rod 414 forms a groove 4141, which connects the first piston structure 42 with the push rod 414.

[0098] In a preferred implementation of the embodiment of the present invention, Figure 5 , Figure 6 , Fig.14 as well as Fig.15 As shown, the first piston structure 42 includes:

[0099] A first plug body 421 is sleeved on the end of the push rod 414 , and a vent hole 4211 is formed at the position of the first plug body 421 corresponding to the groove 4141 ;

[0100] A support member 422 is provided on the first plug body 421 and is arranged around the vent hole 4211;

[0101] The sealing member 423 is disposed on the vent hole 4211 .

[0102] Specifically, the first plug body 421 is sleeved outside the end of the push rod 414 and is engaged with the end of the push rod 414. When the first plug body 421 is sleeved on the end of the push rod 414, the closing piece 423 is opened, and the vent hole 4211 can remove the air between the first plug body 421 and the end of the push rod 414, which is conducive to the sleeve of the first plug body 421 on the end of the push rod 414. After the first plug body 421 is sleeved on the end of the push rod 414, the closing piece 423 closes the vent hole 4211, and a closed space is formed between the first plug body 421, the push rod 414 and the closing piece 423. Even if the first plug body 421 is disengaged from the push rod 414, it is not easy to remove the first plug body 421 from the end of the push rod 414. The closing piece 423 needs to open the vent hole 4211 so that the first plug body 421 can be easily removed from the end of the push rod 414.

[0103] In a preferred implementation of the embodiment of the present invention, Figure 5 and Fig.15 As shown, the support member 422 includes:

[0104] The annular portion 4221 is arranged around the vent hole 4211;

[0105] The plurality of connection portions 4222 and the plurality of embedding portions 4223 are all disposed on a side of the annular portion 4221 facing the push rod 414 .

[0106] Specifically, the support member 422 supports the first plug body 421, so that the first plug body 421 maintains its shape, and the edge of the first plug body 421 outside the support member 422 on the first plug body 421 can still be deformed, so that the edge of the first plug body 421 has good sealing performance. The annular portion 4221 surrounds the vent hole 4211, the diameter of the annular portion 4221 is smaller than the diameter of the first plug body 421, the connecting portion 4222 connects the annular portion 4221 and the first plug body 421, and the embedded portion 4223 is embedded in the first plug body 421, and the embedded portion 4223 surrounds the end of the push rod 414.

[0107] In a preferred implementation of the embodiment of the present invention, Figure 5 , Fig.14 as well as Fig.15 As shown, the first plug body 421 includes:

[0108] The main body 4212 is connected to the connecting portion 4222;

[0109] The barrel portion 4213 is disposed on the main body portion 4212;

[0110] The embedding portion 4223 is embedded in the barrel portion 4213 .

[0111] Specifically, the main body 4212 is connected to the connecting portion 4222, and the diameter of the main body 4212 is larger than the diameter of the annular portion 4221. The vent hole 4211 is provided at the center of the main body 4212. The barrel 4213 surrounds the end of the push rod 414, and the embedded portion 4223 is embedded in the barrel 4213. The barrel 4213 is sleeved outside the end of the push rod 414 and is engaged with the end of the push rod 414.

[0112] In a preferred implementation of the embodiment of the present invention, Fig.14 and Fig.15 As shown, the inner wall of the barrel portion 4213 is circular, and the outer wall of the barrel portion 4213 is non-circular.

[0113] Specifically, the inner side wall of the barrel 4213 is circular, and the end of the push rod 414 is cylindrical, and the end of the push rod 414 can be inserted into the barrel 4213, and the two are clamped. The outer side wall of the barrel 4213 is non-circular. Since the shape of the outer side wall of the barrel 4213 is different from the shape of the inner side wall of the barrel 4213, the thickness of the barrel 4213 is not uniform at all places, but has several places with thicker thickness (i.e., the thick wall of the barrel 4213), and several places with thinner thickness (i.e., the thin wall of the barrel 4213), and the embedded part 4223 is embedded in the thick wall of the barrel 4213. The shape of the outer side wall of the barrel 4213 can be related to the number of embedded parts 4223. If the outer side wall of the barrel 4213 is similar to a quadrilateral, a pentagon or a hexagon, the number of embedded parts 4223 is four, five or six.

[0114] In a preferred implementation of the embodiment of the present invention, Figure 5 , Fig. 9 as well as Fig.10 As shown, a locking structure 50 is provided on the chassis 20 , and the shape of the inner wall of the locking structure 50 is the same as the shape of the outer wall of the cylinder 4213 , and the locking structure 50 is sleeved outside the push rod 414 and the cylinder 4213 .

[0115] Specifically, the locking structure 50 is arranged at the opening structure 21, the shape of the inner wall of the locking structure 50 is the same as the shape of the outer wall of the cylinder 4213, and the locking structure 50 is sleeved outside the cylinder 4213. The cylinder 4213 is limited by the locking structure 50 and cannot rotate. After the push rod 414 pushes the cylinder 4213 out of the locking structure 50, the locking structure 50 can be rotated to disassemble and install the cylinder 4213, that is, to disassemble and install the first piston structure 42.

[0117] Specifically, the outer wall of the push rod 414 forms a slot 4142, which is L-shaped, and the inner wall of the cylinder 4213 forms a clamping member 4214. After the clamping member 4214 is inserted into the slot 4142 and rotated to complete the clamping connection, the clamping member 4214 is limited by the slot 4142.

[0118] In a preferred implementation of the embodiment of the present invention, Fig.14 and Fig.15 As shown, an extrusion protrusion 4215 is arranged outside the first piston structure 42 .

[0119] Specifically, the extrusion protrusion 4215 is located outside the first piston structure 42 and cooperates with the locking structure 50 to lock the first piston structure 42. The extrusion protrusion 4215 is limited by the locking structure 50, and the first driving mechanism 41 cannot drive the first piston structure 42 to extend out of the opening structure 21.

[0120] In a preferred implementation of the embodiment of the present invention, Figure 9-12 As shown, the locking structure 50 includes:

[0121] A fixing portion 51 is sleeved outside the first piston structure 42, and the fixing portion 51 forms a first through hole 511;

[0122] The movable portion 52 is sleeved outside the fixed portion 51 and is detachably connected to the accommodating tube 30;

[0123] The locking pin 53 is located in the first through hole 511 and limits the extrusion protrusion 4215;

[0124] When the movable portion 52 rotates, it drives the locking pin 53 to move in the first through hole 511 .

[0125] Specifically, the fixed portion 51 is sleeved outside the first piston structure 42 and fixed relative to the chassis 20. The movable portion 52 is sleeved outside the fixed portion 51 and rotates relative to the chassis 20. When the accommodating cylinder 30 is connected to the movable portion 52, rotating the accommodating cylinder 30 can drive the movable portion 52 to rotate, and also drive the locking pin 53 to move in the first through hole 511. When the locking pin 53 moves in a direction close to the first piston structure 42, the locking pin 53 limits the extrusion protrusion 4215 to achieve locking; when the locking pin 53 moves in a direction away from the first piston structure 42, the locking pin 53 does not limit the extrusion protrusion 4215, and release is achieved.

[0126] In a preferred implementation of the embodiment of the present invention, Figure 7 and Fig. 9 As shown, a first latching protrusion 35 and a second latching protrusion 36 are arranged outside the tube mouth of the accommodating tube 30; a first sliding groove 23 is formed on the opening structure 21, and the first latching protrusion 35 slides in the first sliding groove 23; a second sliding groove 5212 is formed on the movable part 52, and the second latching protrusion 36 slides in the second sliding groove 5212.

[0127] Specifically, the first clamping protrusion 35 is clamped in the first slide groove 23, and the second clamping protrusion 36 is clamped in the second slide groove 5212. Both the first slide groove 23 and the second slide groove 5212 have a notch and a groove bottom, and both the first slide groove 23 and the second slide groove 5212 are L-shaped. The first clamping protrusion 35 is inserted into the first slide groove 23 from the notch of the first slide groove 23. After the accommodating cylinder 30 is rotated, the first clamping protrusion 35 slides to the groove bottom of the first slide groove 23, so that the accommodating cylinder 30 and the opening structure 21 are clamped together; the second clamping protrusion 36 is inserted into the second slide groove 5212 from the notch of the second slide groove 5212. After the accommodating cylinder 30 is rotated, the second clamping protrusion 36 slides to the groove bottom of the second slide groove 5212, so that the accommodating cylinder 30 and the movable part 52 are clamped together, and during the rotation of the accommodating cylinder 30, the movable part 52 is also driven to rotate.

[0128] In a preferred implementation of the embodiment of the present invention, Fig.10 , Fig.12 as well as Fig.13 As shown, the locking pin 53 is provided with a column 531; the movable part 52 includes:

[0129] The housing 521 is formed with a second through hole 5211 and is detachably connected to the accommodating tube 30;

[0130] A guide body 522 is located in the housing 521, and the guide body 522 is formed with a first guide groove 5221 and a shifting protrusion 5222;

[0131] The first end of the first guide groove 5221 is close to the first piston structure 42 , and the second end of the first guide groove 5221 is away from the first piston structure 42 ; the column 531 is inserted into the first guide groove 5221 , and the shifting protrusion 5222 is inserted into the second through hole 5211 .

[0132] Specifically, after the accommodating cylinder 30 is connected to the housing 521, the housing 521 can be driven to rotate by rotating the accommodating cylinder 30, and the hole wall of the second through hole 5211 can also drive the toggle protrusion 5222 and the guide body 522 to rotate, so that the column 531 slides in the first guide groove 5221, and the locking pin 53 moves relative to the first through hole 511, so as to achieve the locking and releasing of the locking pin 53. The width of the second through hole 5211 is greater than the width of the toggle protrusion 5222, and the toggle protrusion 5222 will contact the hole wall of the second through hole 5211 after moving a certain distance in the second through hole 5211. The rotation of the housing 521 and the rotation of the guide body 522 are not completely synchronized, and the rotation angle of the accommodating cylinder 30 is large, which is conducive to the stable connection of the accommodating cylinder 30 to the opening structure 21. The size of the locking pin 53 is small, and the locking and releasing can be achieved by using a small moving distance. The movable portion 52 is divided into a shell 521 and a guide body 522 , and the two do not rotate completely synchronously, which can be beneficial to the stable connection of the accommodating cylinder 30 and the reduction of the size of the locking pin 53 and the size of the first guide groove 5221 .

[0133] The accommodating cylinder 30 is removed from the opening structure 21, the column 531 is located at the first end of the first guide groove 5221, the locking pin 53 is close to the first piston structure 42, and the locking pin 53 is in a locked state. The accommodating cylinder 30 is assembled to the opening structure 21, the column 531 is located at the second end of the first guide groove 5221, the locking pin 53 is away from the first piston structure 42, and the locking pin 53 is in a loosened state.

[0134] A second sliding groove 5212 is formed on the shell 521 , and the second latching protrusion 36 and the second sliding groove 5212 realize a detachable connection between the accommodating tube 30 and the shell 521 .

[0135] In a preferred implementation of the embodiment of the present invention, Fig.13 and Fig.15 As shown, the outer side of the locking pin 53 forms a first guide surface 532 , and the inner side of the extrusion protrusion 4215 forms a second guide surface 4216 .

[0136] Specifically, if the first driving mechanism 41 has not retracted the first piston structure 42 into the opening structure 21, the accommodating cylinder 30 has been reversely rotated and removed. Since the reverse rotation of the accommodating cylinder 30 will drive the locking pin 53 to move toward the direction close to the first piston structure 42 and lock it, the first driving mechanism 41 continues to retract the first piston structure 42, and the extrusion protrusion 4215 needs to break through the locking pin 53. The first guide surface 532 and the second guide surface 4216 are conducive to the extrusion protrusion 4215 breaking through the locking pin 53, so that the extrusion protrusion 4215 moves to the inner side of the locking pin 53. Therefore, even if the accommodating cylinder 30 is removed in advance, it does not affect the return of the first piston structure 42, nor does it affect the locking pin 53 limiting the extrusion protrusion 4215 of the first piston structure 42 after the first piston structure 42 is returned.

[0137] In a preferred implementation of the embodiment of the present invention, Figure 16-Figure 19 As shown, an outlet structure 33 and a second piston structure 34 are provided outside the through hole 31 ; the outlet structure 33 is connected to the through hole 31 ; the second piston structure 34 rotates relative to the outlet structure 33 and is used to block or open the through hole 31 .

[0138] Specifically, a through hole 31 is formed at the bottom of the receiving cylinder 30 for the ice cream to pass through. The through hole 31 may be circular. The outlet structure 33 is connected to the through hole 31. After the receiving cylinder 30 is assembled to the opening structure 21, the outlet structure 33 faces downward, and the outlet structure 33 guides the ice cream squeezed out of the through hole 31 downward. The second piston structure 34 is rotatably connected to the outlet structure 33, so that the second piston structure 34 blocks or opens the through hole 31.

[0139] In a preferred implementation of the embodiment of the present invention, Fig.17 and Fig.19 As shown, a second guide groove 3321 is formed on the outlet structure 33, and a limit block 342 is formed on the second piston structure 34, and the limit block 342 slides in the second guide groove 3321; the first end of the second guide groove 3321 is close to the through hole 31, and the second end of the second guide groove 3321 is away from the through hole 31.

[0140] Specifically, the limit block 342 is limited by the second guide groove 3321, and the limit block 342 slides in the second guide groove 3321, driving the second piston structure 34 to move toward or away from the through hole 31, so that the second piston structure 34 blocks the through hole 31 or opens the through hole 31. When the limit block 342 is located at the first end of the second guide groove 3321, the second piston structure 34 blocks the through hole 31; when the limit block 342 is located at the second end of the second guide groove 3321, the second piston structure 34 opens the through hole 31.

[0141] In a preferred implementation of the embodiment of the present invention, Figure 8 and Fig. 9 As shown, the bottom of the first slide groove 23 is located in the clockwise direction of the notch of the first slide groove 23 ; the bottom of the second slide groove 5212 is located in the clockwise direction of the notch of the second slide groove 5212 .

[0142] Specifically, the first slide groove 23 extends from the slot opening to the slot bottom in the clockwise direction. The second slide groove 5212 extends from the slot opening to the slot bottom in the clockwise direction. The receiving tube 30 rotates in the clockwise direction to realize the engagement between the first locking protrusion 35 and the first slide groove 23, and the engagement between the second locking protrusion 36 and the second slide groove 5212. Conversely, when the receiving tube 30 rotates counterclockwise, the receiving tube 30 can be removed.

[0143] In a preferred implementation of the embodiment of the present invention, Fig.12 and Fig.17 As shown, the second end of the first guide groove 5221 is located counterclockwise of the first end of the first guide groove 5221 ; the second end of the second guide groove 3321 is located clockwise of the first end of the second guide groove 3321 .

[0144] Specifically, the accommodating cylinder 30 rotates in the clockwise direction, driving the housing 521 and the guide body 522 to rotate in the clockwise direction, the column 531 moves from the first end to the second end of the first guide groove 5221, and the locking pin 53 moves away from the first piston structure 42 until it is in a released state. Conversely, the accommodating cylinder 30 rotates in the counterclockwise direction, driving the housing 521 and the guide body 522 to rotate in the counterclockwise direction, the column 531 moves from the second end to the first end of the first guide groove 5221, and the locking pin 53 moves close to the first piston structure 42 until it is in a locked state.

[0145] The second piston structure 34 rotates in the clockwise direction, and the limit block 342 moves from the first end to the second end of the second guide groove 3321, and the second piston structure 34 gradually opens the through hole 31. Conversely, the second piston structure 34 rotates in the counterclockwise direction, and the limit block 342 moves from the second end to the first end of the second guide groove 3321, and the second piston structure 34 gradually blocks the through hole 31.

[0146] In a preferred implementation of the embodiment of the present invention, Fig.17 As shown, the outlet structure 33 includes:

[0147] A first cylinder 331 is arranged around the through hole 31;

[0148] A second cylinder 332, surrounding the first cylinder 331;

[0149] The channel 333 is provided in the first cylinder 331 and passes through the second cylinder 332 .

[0150] Specifically, the first cylinder 331 and the second cylinder 332 are both located outside the accommodating cylinder 30, the first cylinder 331 surrounds the outside of the through hole 31, and the second cylinder 332 surrounds the outside of the first cylinder 331. The channel 333 penetrates the first cylinder 331 and the second cylinder 332, and the ice cream discharged from the through hole 31 enters the first cylinder 331 and then is discharged through the channel 333. The second piston structure 34 is movably connected to the second cylinder 332 and seals the through hole 31.

[0151] In a preferred implementation of the embodiment of the present invention, Fig.17 and Fig.19 As shown, the second cylinder 332 is provided with a second guide groove 3321; the second piston structure 34 includes:

[0152] A cover body 341 is sleeved outside the second cylinder 332;

[0153] A limit block 342 is disposed on the inner wall of the cover body 341 and is inserted into the second guide groove 3321 and slides in the second guide groove 3321;

[0154] The second plug 343 is disposed at the inner bottom of the cover 341 and is inserted into the first cylinder 331 to seal the through hole 31 .

[0155] Specifically, the cover body 341 covers the second cylinder 332, and a notch 3411 is provided on the cover body 341, and the notch 3411 avoids the channel 333. The second plug body 343 is inserted into the first cylinder 331 and seals the through hole 31. When the limit block 342 slides in the second guide groove 3321, the cover body 341 moves relative to the second cylinder 332 and the second plug body 343 moves relative to the first cylinder 331, and the movement trajectory of the cover body 341 and the movement trajectory of the second plug body 343 are both extension trajectories of the second guide groove 3321. With the second guide groove 3321, the movement of the second plug body 343 is a composite movement of moving away from the accommodating cylinder 30 and rotating relative to the first cylinder 331, which is conducive to reducing the sliding friction between the second plug body 343 and the first cylinder 331, and facilitating the opening of the second plug body 343.

[0156] The second guide groove 3321 is arranged to be inclined relative to the axial direction of the first cylinder 331 . The second guide groove 3321 is substantially in the shape of a spiral curve. The second guide groove 3321 may also be an inclined hole.

[0157] In a preferred implementation of the embodiment of the present invention, Fig.17As shown, a first flat groove 3322 and a second flat groove 3323 are formed on the opening structure 21 , which are respectively connected to the two ends of the second guide groove 3321 ; the limiting block 342 slides in the first flat groove 3322 and the second flat groove 3323 , respectively.

[0158] Specifically, the first flat groove 3322 and the second flat groove 3323 are arranged in the second cylinder 332. The stopper 342 is in the shape of an elongated strip, and the elongated stopper 342 extends in the horizontal direction. The stopper 342 can move to the first flat groove 3322 and the second flat groove 3323. The first flat groove 3322 and the second flat groove 3323 both extend in the horizontal direction. The first flat groove 3322 and the second flat groove 3323 are respectively located at the two ends of the second guide groove 3321. For example, the first flat groove 3322 is located at one end of the second guide groove 3321 close to the accommodating cylinder 30, and the second flat groove 3323 is located at one end of the second guide groove 3321 away from the accommodating cylinder 30. When the stopper 342 moves into the first flat groove 3322, the second plug body 343 seals the through hole 31, and the first driving mechanism 41 pushes the first piston structure 42 but cannot push the second piston structure 34 to rotate horizontally to open the outlet structure 33, so the second piston structure 34 is in a closed and locked state. When the stopper 342 moves into the second flat groove 3323, the first plug body 421 is away from the through hole 31, the outlet structure 33 is fully opened, and the second piston structure 34 is in an open and locked state. When the stopper 342 is located at a position where the second guide groove 3321 is close to the first flat groove 3322, when the first piston structure 42 moves, the second piston structure 34 can be pushed open, the second piston structure 34 is not locked, and the second piston structure 34 is in a closed and unlocked state. When the stopper 342 is located at a position where the second guide groove 3321 is close to the second flat groove 3323, the second piston structure 34 is in an open and unlocked state.

[0159] A first identification portion 32 is provided on the outside of the accommodating cylinder 30, and a second identification portion 3412 is provided on the cover body 341. The first identification portion 32 and the second identification portion 3412 are used to identify the open state, closed state and locked state of the second piston structure 34. When the first identification portion 32 and the second identification portion 3412 are close to each other, the second piston structure 34 is in a closed and locked state; when the first identification portion 32 and the second identification portion 3412 are staggered in the horizontal direction, the second piston structure 34 is in a closed and unlocked state; when the first identification portion 32 and the second identification portion 3412 are staggered in the horizontal direction and separated in the vertical direction, the second piston structure 34 is in an open state.

[0160] The ice cream machine also includes:

[0161] The mixing device 60 is disposed on the base 10 and the housing 20, and is used for stirring the ice cream raw materials to form ice cream.

[0162] Specifically, the ice cream raw materials are more, and more ice cream can be formed at one time by the mixing device 60, and multiple portions of ice cream can be squeezed out by the squeezing device 40. The ice cream raw materials can include ice cubes, milk, milk powder, cream, edible sugar, salt, additives, etc.

[0163] The mixing device 60 comprises:

[0164] A second driving mechanism 61 is disposed in the chassis 20;

[0165] The sleeve structure 62 is placed on the base 10;

[0166] A mixer 63, disposed on the sleeve structure 62;

[0167] The second driving mechanism 61 is used to drive the mixer 63 to rise, fall and rotate.

[0168] Specifically, the container 30 is used to load the ice cream raw materials and the ice cream formed by the ice cream raw materials. The container 30 is assembled in the sleeve structure 62. The sleeve structure 62 includes a cover and a body. The cover and the body are detachably connected. After opening the cover, the container 30 is placed in the body, or the container 30 in the body is taken out. Figure 3 As shown, the second driving mechanism 61 is detachably connected to the mixer 63 and is used to drive the mixer 63 to rise and fall and rotate. The rising and falling and rotation of the mixer 63 can be performed simultaneously. The mixer 63 is detachably assembled on the sleeve structure 62 and rotates relative to the sleeve structure 62. Specifically, it is assembled on the cylinder cover of the sleeve structure 62. After the second driving mechanism 61 is connected to the mixer 63, the mixer 63 and the sleeve structure 62 can be separated. The mixer 63 has the functions of stirring and cutting the ice cream raw materials. The ice cream raw materials are crushed by cutting and mixed by stirring.

[0169] The second piston structure 34 rotates relative to the outlet structure 33, and can be indirectly pushed open by the first piston structure 42. When the accommodating cylinder 30 is assembled in the sleeve structure 62, the second piston structure 34 and the outlet structure 33 are closed under the gravity of the accommodating cylinder 30, and the ice cream will not leak out of the outlet structure 33.

[0170] In the present application, the connection between the second piston structure 34 and the outlet structure 33 is relatively flexible, and the second piston structure 34 can be pushed open by the first piston structure 42. Even if the second piston structure 34 is forgotten to be opened manually, it does not affect the opening of the second piston structure 34 and the extrusion of the ice cream. When the air pressure in the accommodating cylinder 30 is increased, it is also beneficial to expel the large-pore foam in the ice cream, making the foam of the ice cream more delicate.

[0171] In a preferred implementation of the embodiment of the present invention, Figure 3 and Figure 4 As shown, the second driving mechanism 61 includes:

[0172] A rotation driver 611 is disposed in the chassis 20;

[0173] A second transmission assembly 612 connected to the output shaft of the rotary driver 611;

[0174] A movable shaft 613 connected to the second transmission assembly 612 and connected to the mixer 63;

[0175] A lifting assembly 614 connected to the movable shaft 613;

[0176] The lifting driver 615 is connected to the lifting component 614 .

[0177] Specifically, the second driving mechanism 61 is used to drive the mixer 63 to rise and fall and rotate, specifically, the mixer 63 is driven to rotate through the rotating driver 611, and the mixer 63 is driven to rise and fall through the lifting driver 615. The rotating driver 611 is located on the side of the sleeve structure 62, and the rotating driver 611 transmits the driving force to the mixer 63 through the second transmission component 612 and the movable shaft 613. The lifting driver 615 transmits the driving force to the mixer 63 through the lifting component 614 and the movable shaft 613. The movable shaft 613 can rise and fall and rotate.

[0178] The second transmission assembly 612 can adopt a gear train transmission assembly, and the movable shaft 613 includes: a sleeve and a shaft core, the sleeve is connected to the second transmission assembly 612, and the sleeve rotates relative to the chassis 20. The shaft core is located in the sleeve, and is respectively connected to the lifting assembly 614 and the mixer 63, and the shaft core slides in the sleeve, and the sleeve and the shaft core cannot rotate relative to each other. The second transmission assembly 612 transmits the driving force of the rotating driver 611 to the sleeve, so that the sleeve and the shaft core rotate together, and the mixer 63 rotates. The lifting assembly 614 transmits the driving force of the lifting driver 615 to the shaft core, so that the shaft core slides relative to the sleeve, and the mixer 63 is lifted and lowered. The lifting assembly 614 can adopt a lead screw 413, and the lifting driver 615 drives the screw of the lead screw to rotate, and converts it into the movement of the nut of the lead screw to promote the lifting and lowering of the shaft core.
