[0044] The embodiment simplifies the transmission structure of the ice cream machine, reduces the noise problem of the ice cream machine during use, and prolongs the service life of the motor. The stirring motor 41 and the lifting motor 32 are fixedly arranged in the shell 1, so that the motor does not move up and down during operation, thereby solving the problem that the lifting motor 32 and the stirring motor 41 may be disconnected or damaged, ensuring the safety of the motor. The driving end of the stirring motor 41 is connected with the transmission mechanism 42, and the transmission mechanism 42 is connected with the stirring shaft 2, so that the stirring motor 41 drives the transmission mechanism 42 to drive the stirring shaft 2 to rotate, thereby realizing stirring. The transmission mechanism 42 is arranged on the lifting mechanism 31 and synchronously lifts with the lifting mechanism 31. The lifting mechanism 31 is connected with the stirring shaft 2 to drive the stirring shaft 2 to lift, so that the stirring shaft 2 is inserted into the stirring cup. The lifting mechanism 31 is located in the interior of the shell 1. The lifting motor 32 is used to drive the stirring shaft 2 and the lifting mechanism 31 to lift. The stirring motor 41 is used to drive the stirring shaft 2 to rotate circumferentially. The lifting mechanism 31 is connected with the driving end of the lifting motor 32. The transmission mechanism 42 is connected with the driving end of the stirring motor 41. The stirring shaft 2 is connected with the transmission mechanism 42. The stirring shaft 2 and the transmission mechanism 42 are both installed on the lifting mechanism 31. Therefore, when the lifting motor 32 is started, the lifting mechanism 31 is driven to lift, so as to drive the stirring shaft 2 and the transmission mechanism 42 to synchronously lift and move. When the stirring motor 41 is started, the stirring motor 41 drives the transmission mechanism 42 to start, so as to drive the stirring shaft 2 to rotate circumferentially and stir.

[0045] In the embodiment, the ice cream machine with easy transmission further comprises a stirring cup assembly 6 mounted on the shell 1, the shell 1 is provided with a mounting space 11, the stirring cup assembly 6 can be mounted into the mounting space 11, the stirring shaft 2 extends out of the shell 1 and enters the mounting space 11, so as to facilitate stirring of the stirring shaft 2. Specifically, the stirring cup assembly 6 comprises a cup body 61 and a cup cover 62, ice cream stirring materials are placed in the cup body 61, and the cup cover 62 covers the opening of the cup body 61. An upper portion of the cup cover 62 is provided with an opening hole for insertion of the stirring shaft 2. Under the driving of the lifting assembly 3, one end of the stirring shaft 2 extends out of the shell 1 and enters the inside of the cup body 61 through the opening hole on the cup cover 62, so as to ascend and descend in the cup body 61 for stirring. The stirring cup assembly 6 further comprises a stirring knife 63 located in the cup body 61. The stirring knife 63 is used to be connected with the stirring shaft 2, so that the stirring shaft 2 drives the stirring knife 63 to rotate, so as to cut and stir the stirring materials in the cup body 61. When the stirring knife 63 is not connected with the stirring shaft 2, the stirring knife 63 is located on the inner side surface of the cup cover 62. When the stirring shaft 2 enters the cup body 61 through the opening hole of the cup cover 62, the stirring shaft 2 is automatically connected with the stirring knife 63 synchronously, so as to quickly connect the stirring shaft 2 with the stirring knife 63, to drive the stirring knife 63 to descend. When the stirring is completed, the stirring shaft 2 ascends to the position of the cup cover 62, the stirring shaft 2 is automatically disconnected with the stirring knife 63, the stirring knife 63 is connected with the inner side surface of the cup cover 62 again, and the stirring shaft 2 extends out of the cup body 61 through the opening hole of the cup cover 62 and is retracted into the shell 1. It can be understood that the stirring knife 63 positioned on the inner side surface of the cup cover 62 can be connected by buckling or by magnetic attraction, which is not limited herein.

[0046] Further, the transmission mechanism 42 comprises a synchronous belt 421, a first pulley 422 and a second pulley 423. The synchronous belt 421 is connected with the first pulley 422 and the second pulley 423 respectively. The first pulley 422 is connected with the driving end of the stirring motor 41, and the second pulley 423 is connected with the stirring shaft 2. One end of the stirring shaft 2 is fixedly connected with the second pulley 423, and the other end of the stirring shaft 2 penetrates through the shell 1 and can extend out of the shell 1 or retract into the shell 1, so as to facilitate use and storage of the stirring shaft 2. The driving end of the stirring motor 41 is connected with the first pulley 422. The first pulley 422 and the second pulley 423 are connected by the synchronous belt 421. When the first pulley 422 rotates under the driving of the stirring motor 41, the first pulley 422 drives the synchronous belt 421 to move, the synchronous belt 421 is transmitted to the second pulley 423 and drives the second pulley 423 to rotate, so as to rotate the stirring shaft 2. The transmission of the synchronous belt 421 reduces the noise problem of the ice cream machine in use, and makes the transmission structure of the ice cream machine simpler and the assembly more convenient.

[0047] Further, the diameter of the first pulley 422 is smaller than the diameter of the second pulley 423. In the embodiment, the diameters of the first pulley 422 and the second pulley 423 are different, so that the linear speed of the synchronous belt 421 can be changed in rotation, and when the synchronous belt 421 is transmitted from the first pulley 422 to the second pulley 423, the linear speed of the synchronous belt 421 on the second pulley 423 is increased, so that the rotation speed of the second pulley 423 is increased, and the rotation speed of the stirring shaft 2 is increased, and the diameter of the first pulley 422 is smaller than the diameter of the second pulley 423, so that the tension and running characteristics of the synchronous belt 421 can be changed, so as to reduce the noise and vibration in the transmission assembly 4. It should be noted that the surfaces of the first pulley 422 and the second pulley 423 are provided with convex block and groove structures, so as to increase the friction between the synchronous belt 421 and the first pulley 422 and the second pulley 423, and prevent the synchronous belt 421 from slipping and affecting use.

[0048] Further, it can be specifically referred to Figure 5 that the edges of the second pulley 422 on the upper and lower sides are provided with stop blocks 4231, and the synchronous belt 421 is located between the intervals of the stop blocks 4231. The stop blocks 4231 are used to limit the deviation of the synchronous belt 421, and the stop blocks 4231 are respectively located on the edges of the second pulley 423, and the stop blocks 4231 between the two edges form an interval, and the synchronous belt 421 is located in the interval between the stop blocks 4231, so that the synchronous belt 421 will not slip out of the second pulley 423 and be separated from the second pulley 423 when driving the second pulley 423 to rotate. It should be noted that the stop blocks 4231 are provided in plurality and are arranged in the circumferential direction along the edges of the second pulley 423. It can be understood that the stop blocks 4231 can also extend in the circumferential direction along the edges of the second pulley 423 and be connected at the head and tail, so as to limit the deviation of the synchronous belt 421. In other embodiments, the stop blocks 4231 can also be arranged on the edges of the first pulley 422, so as to ensure that the synchronous belt 421 will not be separated from the first pulley 422.

[0049] Further, it can be specifically referred to Figure 2 and Figure 3The shell 1 is internally provided with a fixed support assembly 5, which comprises an upper support plate 51, a lower support plate 52 and a support shaft 53 connecting the upper support plate 51 and the lower support plate 52, the stirring motor 41 is fixed to the lower support plate 52, and the lifting assembly 3 is lifted along the support shaft 53. The fixed support assembly 5 is fixed to the inside of the shell 1, and the fixed support assembly 5 is used to improve the stability of the stirring shaft 2 during lifting. The upper support plate 51 and the lower support plate 52 are fixedly arranged in the shell 1 at intervals, the support shaft 53 is located between the upper support plate 51 and the lower support plate 52, the two ends of the support shaft 53 are fixedly connected with the upper support plate 51 and the lower support plate 52 respectively, and the connection mode can be screw fixing or buckle fixing. In the embodiment, four support shafts 53 are arranged, and the four support shafts 53 are located at the four corners of the upper support plate 51 and the lower support plate 52 respectively, so that the upper support plate 51 and the lower support plate 52 are more stable. The stirring motor 41 is fixed to the lower support plate 52 by screws. The lifting assembly 3 is located between the upper support plate 51 and the lower support plate 52, and moves up and down along the extension direction of the support shaft 53. The stirring shaft 2 penetrates through the lower support plate 52 and extends out of the shell 1. The position where the lower support plate 52 is penetrated by the stirring shaft 2 is provided with a gasket, which surrounds the stirring shaft 2, so that the gap between the stirring shaft 2 and the lower support plate 52 is filled, thereby limiting the left and right shaking of the stirring shaft 2 during lifting, and improving the stability of the stirring shaft 2.

[0050] Further, the driving end of the stirring motor 41 is provided with a transmission rod 411, the first pulley 422 is provided with a first driving hole 4221 for the transmission rod 411 to pass through, and the transmission rod 411 drives the first pulley 422 to rotate circumferentially. Specifically, the stirring motor 41 is fixed to the side of the lower support plate 52 away from the upper support plate 51, so as to avoid affecting the lifting assembly 3. The driving end of the stirring motor 41 is provided with a transmission rod 411, which penetrates through the lower support plate 52 and extends to the upper support plate 51. The end of the transmission rod 411 is inserted into the upper support plate 51 and can rotate relative to the upper support plate 51. The upper support plate 51 and the lower support plate 52 limit the left and right shaking of the transmission rod 411, thereby improving the stability of the transmission rod 411. In the embodiment, the first pulley 422 is sleeved on the transmission rod 411. When the stirring motor 41 starts, the transmission rod 411 rotates, thereby making the first pulley 422 rotate circumferentially around the axis of the transmission rod 411. The first pulley 422 drives the second pulley 423 to rotate through the synchronous belt 421, thereby driving the stirring shaft 2 to rotate.

[0051] Further, the first driving hole 4221 and the transmission rod 411 are both in semicircular structure. The rod body of the transmission rod 411 is in semicircular structure, specifically, the transmission rod 411 is provided with a limiting plane on one side, so that the cross section of the transmission rod 411 is in semicircular structure. The cross section of the first driving hole 4221 is the same as that of the transmission rod 411. After the transmission rod 411 passes through the first driving hole 4221, the first pulley 422 cannot rotate relative to the transmission rod 411 under the blocking of the hole wall of the first driving hole 4221 and the limiting plane, so as to avoid the idling of the transmission rod 411 in the first driving hole 4221. When the transmission rod 411 is self-transmitted, the limiting plane on the transmission rod 411 is in contact with the hole wall of the first driving hole 4221 and pushes the hole wall of the first driving hole 4221 to rotate, so as to drive the first pulley 422 to rotate. It can be understood that the cross sections of the rod body of the transmission rod 411 are the same, so that the first pulley 422 can slide up and down along the axial direction of the transmission rod 411. It should be noted that the cross sections of the transmission rod 411 and the first driving hole 4221 can also be in non-circular structure such as ellipse, rectangle or triangle, so that the first pulley 422 can not only move up and down along the transmission rod 411, but also be driven by the transmission rod 411 to rotate circumferentially.

[0052] It can be understood that the second pulley 423 is fixedly connected with the end of the stirring shaft 2, so that the second pulley 423 can drive the stirring shaft 2 to rotate when the second pulley 423 rotates. Specifically, the second pulley 423 is provided with a second driving hole 4232 for inserting the end of the stirring shaft 2. The cross section of the second driving hole 4232 is in non-circular structure. The cross section of the end of the stirring shaft 2 inserted into the second driving hole 4232 is the same as that of the second driving hole 4232. The end of the stirring shaft 2 is further provided with a stop block 4231. When the end of the stirring shaft 2 is inserted into the second driving hole 4232, the stop block 4231 is located outside the second driving hole 4232, so as to block the up and down movement of the second pulley 423 relative to the stirring shaft 2.

[0053] Further, the lifting mechanism 31 comprises a lifting platform 311 and a screw rod 312, the lifting platform 311 is located between the upper support plate 51 and the lower support plate 52, the lifting motor 32 is connected with the screw rod 312 and drives the screw rod 312 to rotate, the lifting platform 311 is provided with a tooth socket 3112 for the screw rod 312 to pass through, and the inner wall of the tooth socket 3112 is provided with a thread matched with the screw rod 312.

[0054] In the embodiment, the screw rod 312 is located between the upper support plate 51 and the lower support plate 52, and the screw rod 312 is rotationally connected to the upper support plate 51, so that the screw rod 312 can rotate relative to the upper support plate 51; the lifting motor 32 is connected to one end of the screw rod 312 close to the lower support plate 52 and can drive the screw rod 312 to rotate axially. Specifically, the driving end of the lifting motor 32 is provided with a driving groove for inserting the end of the screw rod 312, the driving groove is non-circular, the screw rod 312 is inserted into the driving groove, so that the screw rod 312 is limited in the circumferential direction relative to the driving groove; when the lifting motor 32 is started, the driving groove rotates circumferentially to drive the screw rod 312 to rotate. The other end of the screw rod 312 passes through the lifting platform 311 and is connected to the upper support plate 51. The lifting platform 311 is provided with a tooth socket 3112 for the screw rod 312 to pass through. The outer side of the screw rod 312 is provided with a thread, and the inner wall of the tooth socket 3112 is also provided with a thread matched with the screw rod 312. When the lifting motor 32 drives the screw rod 312 to rotate forward or reversely, the thread on the screw rod 312 engages with the thread on the tooth socket 3112 and moves relatively, so that the tooth socket 3112 lifts along the axis of the screw rod 312. Since the tooth socket 3112 is fixedly arranged on the lifting platform 311, the lifting platform 311 lifts along the screw rod 312. It should be noted that the driving end of the lifting motor 32 is connected to the screw rod 312 to drive the screw rod 312 to rotate, and the screw rod 312 drives the lifting platform 311 to lift. In other embodiments, the lifting motor 32 can be directly connected to the lifting platform 311, or the driving end of the lifting platform 311 drives the lifting platform 311 to move through a belt or a gear.
