[0039] One embodiment of the present invention provides an easy-to-transmit ice cream machine, referring to Figures 1 to 6 ,include:

[0040] Shell 1;

[0041] A stirring shaft 2, movably extending from the housing 1;

[0042] The lifting assembly 3 includes a lifting motor 32 and a lifting mechanism 31. The lifting motor 32 is fixedly arranged in the housing 1 and drives the lifting mechanism 31 to move up and down. The stirring shaft 2 is connected to the lifting mechanism 31 and moves up and down synchronously.

[0043] The transmission assembly 4 includes a stirring motor 41 and a transmission mechanism 42. The stirring motor 41 is fixedly arranged in the shell 1 and drives the transmission mechanism 42 to rotate. The transmission mechanism 42 is arranged on the lifting mechanism 31. The transmission mechanism 42 is connected to the stirring shaft 2 and is used to drive the stirring shaft 2 to rotate.

[0044] This embodiment simplifies the transmission structure of the ice cream machine, reduces the noise problem when the ice cream machine is in use, and increases 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 will not be lifted or moved during operation, thereby solving the problem that the lifting motor 32 and the stirring motor 41 will not have line disconnection or motor damage, ensuring the safety of motor use. The driving end of the stirring motor 41 is connected to the transmission mechanism 42, and the transmission mechanism 42 is connected to the stirring shaft 2, so that the stirring motor 41 drives the transmission mechanism 42 to drive the stirring shaft 2 to rotate, thereby achieving stirring. The transmission mechanism 42 is arranged on the lifting mechanism 31 and rises and falls synchronously with the lifting mechanism 31. The lifting mechanism 31 is connected to the stirring shaft 2 to drive the stirring shaft 2 to rise and fall, so that the stirring shaft 2 is inserted into the stirring cup. The lifting mechanism 31 is located inside the shell 1, the lifting motor 32 is used to drive the stirring shaft 2 and the lifting mechanism 31 to rise and fall, the stirring motor 41 is used to drive the stirring shaft 2 to rotate circumferentially, the lifting mechanism 31 is connected to the driving end of the lifting motor 32, the transmission mechanism 42 is connected to the driving end of the stirring motor 41, the stirring shaft 2 is connected to the transmission mechanism 42, and the stirring shaft 2 and the transmission mechanism 42 are both installed on the lifting mechanism 31, so that when the lifting motor 32 is started, the lifting mechanism 31 is driven to rise and fall to drive the stirring shaft 2 and the transmission mechanism 42 to rise and fall synchronously, and when the stirring motor 41 is started, the stirring motor 41 drives the transmission mechanism 42 to start to drive the stirring shaft 2 to rotate circumferentially for stirring.

[0045] In this embodiment, the easy-to-transmit ice cream machine also includes a stirring cup assembly 6 installed on the shell 1, and the shell 1 is provided with an installation space 11. The stirring cup assembly 6 can be installed in the installation space 11, and the stirring shaft 2 extends out of the shell 1 and enters the installation space 11, so as to facilitate the stirring of the stirring shaft 2. Specifically, the stirring cup assembly 6 includes a cup body 61 and a cup cover 62. The ice cream stirring material is placed in the cup body 61, and the cup cover 62 covers the opening of the cup body 61. The upper part of the cup cover 62 is provided with an opening for inserting the stirring shaft 2. Under the drive of the lifting assembly 3, one end of the stirring shaft 2 extends out of the shell 1 and enters the interior of the cup body 61 through the opening on the cup cover 62, so as to lift and stir back and forth in the cup body 61. The stirring cup assembly 6 also includes a stirring knife 63 located in the cup body 61, and the stirring knife 63 is used to connect with the stirring shaft 2, so as to The stirring shaft 2 drives the stirring blade 63 to rotate to stir and cut the stirring material inside the cup body 61. The stirring blade 63 is located on the inner side of the cup cover 62 when it is not connected to the stirring shaft 2. When the stirring shaft 2 enters the cup body 61 through the opening of the cup cover 62, it is automatically engaged with the stirring blade 63, thereby realizing a quick connection between the stirring shaft 2 and the stirring blade 63 to drive the stirring blade 63 to descend. When the stirring is completed, the stirring shaft 2 rises to the position of the cup cover 62, the stirring shaft 2 automatically disconnects from the stirring blade 63, and the stirring blade 63 is engaged with the inner side of the cup cover 62 again. The stirring shaft 2 extends out of the cup body 61 through the opening of the cup cover 62 and retracts into the shell 1. It can be understood that the stirring blade 63 can be positioned on the inner side of the cup cover 62 by snap-fitting or by magnetic attraction, which is not limited here.

[0046] Furthermore, the transmission mechanism 42 includes a synchronous belt 421, a first pulley 422 and a second pulley 423, the synchronous belt 421 connects the first pulley 422 and the second pulley 423 respectively, the first pulley 422 is connected to the driving end of the stirring motor 41, and the second pulley 423 is connected to the stirring shaft 2. One end of the stirring shaft 2 is fixedly connected to the second pulley 423, and the other end of the stirring shaft 2 passes through the shell 1 and can extend out of the shell 1 or retract into the shell 1, so that the stirring shaft 2 is convenient to use and store, and the driving end of the stirring motor 41 is connected to the first pulley 422, and the first pulley 422 and the second pulley 423 are connected through a synchronous belt 421. When the first pulley 422 rotates under the drive of the stirring motor 41, the first pulley 422 drives the synchronous belt 421 to move, and the synchronous belt 421 is transmitted to the second pulley 423 and drives the second pulley 423 to rotate, thereby rotating the stirring shaft 2. The transmission of the synchronous belt 421 reduces the noise problem of the ice cream machine during use, makes the transmission structure of the ice cream machine simpler, and makes assembly more convenient.

[0047] Further, the diameter of the first pulley 422 is smaller than the diameter of the second pulley 423. In this embodiment, the diameters of the first pulley 422 and the second pulley 423 are different, so that the two pulleys can change the linear velocity of the synchronous belt 421 during rotation. When the synchronous belt 421 is transferred from the first pulley 422 to the second pulley 423, the linear velocity of the synchronous belt 421 on the second pulley 423 will increase, so that the rotation speed of the second pulley 423 is increased, thereby increasing the rotation speed of the stirring shaft 2, and the diameter of the first pulley 422 is smaller than the diameter of the second pulley 423, which can change the tension and running characteristics of the synchronous belt 421 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 both provided with bumps and grooves to increase the friction between the synchronous belt 421 and the first pulley 422 and the second pulley 423 to prevent the synchronous belt 421 from slipping and affecting the use.

[0048] For further details, please refer to Figure 5 , the edges of the upper and lower sides of the second pulley 422 are both provided with blocks 4231, and the synchronous belt 421 is located between the intervals of the blocks 4231. The blocks 4231 are used to limit the deviation of the synchronous belt 421. The blocks 4231 are respectively located at the edges of the two sides of the second pulley 423, and an interval is formed between the blocks 4231 on both sides. The synchronous belt 421 is located in the interval between the blocks 4231, so that when the synchronous belt 421 drives the second pulley 423 to rotate, it will not slide out from the side of the second pulley 423 and cause it to be separated from the second pulley 423. It should be noted that there are multiple blocks 4231, and they are arranged circumferentially along the edge of the second pulley 423. It can be understood that the blocks 4231 can also extend circumferentially along the edge of the second pulley 423 and be connected end to end, so as to limit the deviation of the synchronous belt 421. In other embodiments, the blocks 4231 can also be set at the edge 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, please refer to Figure 2 and Figure 3, a fixed support assembly 5 is arranged in the shell 1, and the fixed support assembly 5 includes an upper support plate 51, a lower support plate 52 and a support shaft 53, the support shaft 53 connects 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 and lowered along the support shaft 53. The fixed support assembly 5 is fixed inside the shell 1, and the fixed support assembly 5 is used to improve the stability of the stirring shaft 2 when it is lifted and lowered. The upper support plate 51 and the lower support plate 52 are fixedly arranged in the shell 1 at intervals, and 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 to the upper support plate 51 and the lower support plate 52 respectively, and the connection method can be threaded fixing or snap fixing. In this embodiment, four support shafts 53 are arranged, and the four support shafts 53 are respectively located at the four corners of the upper support plate 51 and the lower support plate 52, so that the upper support plate 5 1 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 component 3 is located between the upper support plate 51 and the lower support plate 52, and the lifting component 3 moves up and down along the extension direction of the support shaft 53, the stirring shaft 2 passes through the lower support plate 52 and extends out of the shell 1, and a gasket is provided at the position of the lower support plate 52 for the stirring shaft 2 to pass through, and the gasket surrounds the stirring shaft 2, so that the gap between the stirring shaft 2 and the lower support plate 52 is filled, so that the lower support plate 52 limits the stirring shaft 2 from shaking left and right when lifting, thereby improving the stability of the stirring shaft 2.

[0050] Furthermore, a driving rod 411 is provided at the driving end of the stirring motor 41 , and the first belt pulley 422 is provided with a first driving hole 4221 for the driving rod 411 to pass through, and the driving rod 411 drives the first belt pulley 422 to rotate circumferentially. Specifically, the stirring motor 41 is fixed to the side of the lower support plate 52 facing away from the upper support plate 51 to avoid affecting the lifting assembly 3. The driving end of the stirring motor 41 is provided with a transmission rod 411, which is penetrated by 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 this embodiment, the first pulley 422 is sleeved on the transmission rod 411. When the stirring motor 41 is started, the transmission rod 411 rotates, so that the first pulley 422 synchronously rotates 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, so that the second pulley 423 drives the stirring shaft 2 to rotate.

[0051] Furthermore, the cross-sections of the first driving hole 4221 and the transmission rod 411 are both semicircular. The rod body of the transmission rod 411 is a semi-cylindrical structure. Specifically, a limited position plane is set on one side of the transmission rod 411, so that the cross-section of the transmission rod 411 is a semicircular structure. The cross-section of the first driving hole 4221 is the same as the cross-section of the transmission rod 411. After the transmission rod 411 passes through the first driving hole 4221, the first pulley 422 and the transmission rod 411 cannot rotate relative to each other under the obstruction of the hole wall and the limiting surface of the first driving hole 4221, so as to prevent the transmission rod 411 from idling in the first driving hole 4221. When the transmission rod 411 rotates, the limiting plane on the transmission rod 411 and the first pulley 422 are mutually opposite. The hole wall of the driving hole 4221 fits against and pushes the hole wall of the first driving hole 4221 to rotate, thereby driving 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 rise and fall and slide back and forth along the axial direction of the transmission rod 411. It should be noted that the cross-section of the transmission rod 411 and the cross-section of the first driving hole 4221 can also be non-circular structures such as elliptical, rectangular or triangular, so that the first pulley 422 can both be lifted and moved along the transmission rod 411, and can also be driven by the transmission rod 411 to rotate circumferentially.

[0052] It can be understood that the second pulley 423 is fixedly connected to the end of the stirring shaft 2, so that the second pulley 423 can drive the stirring shaft 2 to rotate when it rotates. Specifically, the second pulley 423 is provided with a second drive hole 4232 for inserting the end of the stirring shaft 2. The cross-section of the second drive hole 4232 is a non-circular structure. The cross-section of one end of the stirring shaft 2 inserted into the second drive hole 4232 is the same as the cross-section of the second drive hole 4232. A stopper 4231 is also provided at the end of the stirring shaft 2. When the end of the stirring shaft 2 is inserted into the second drive hole 4232, the stopper 4231 is located on the outside of the second drive hole 4232 to prevent the second pulley 423 from moving up and down relative to the stirring shaft 2.

[0053] Furthermore, the lifting mechanism 31 includes 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 to the screw rod 312 and drives the screw rod 312 to rotate. The lifting platform 311 is provided with a toothed sleeve 3112 for the screw rod 312 to pass through. The inner wall of the toothed sleeve 3112 is provided with a thread that matches the screw rod 312. The lifting platform 311 is arranged between the upper support plate 51 and the lower support plate 52. The lifting motor 32 is fixed to the lower support plate 52 by screws to prevent the lifting motor 32 from shaking and causing damage to the line. The lifting motor 32 drives the lifting platform 311 to move up and down along the support shaft 53. The first pulley 422 and the second pulley 423 are installed on the lifting platform 311 and move up and down with the lifting platform 311. In this embodiment, the four support shafts 53 are all passed through the lifting platform 311 to make the lifting platform 311 more stable when lifting. The lifting platform 311 is on the support shaft 53. A shaft sleeve 3111 is fixedly provided at the position where the support shaft 53 is passed through. The shaft sleeve 3111 is provided with a shaft sleeve 3111 hole for the support shaft 53 to pass through. Four shaft sleeves 3111 are provided, and the four shaft sleeves 3111 respectively correspond to the four support shafts 53, so that the lifting platform 311 and the support shaft 53 can be slidably matched to ensure the stability of the up and down movement of the lifting platform 311. It should be noted that the driving end of the lifting motor 32 drives the lifting platform 311 to lift and lower, and the lifting motor 32 can also be replaced by other structures. For example, the lifting motor 32 is replaced by a pneumatic structure.

[0054] In the present 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 rotatably connected to the upper support plate 51, so that the screw rod 312 can rotate relative to the upper support plate 51, and 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 the end of the screw rod 312 to be inserted, and the driving groove is non-circular. The screw rod 312 is inserted into the driving groove so that the screw rod 312 is circumferentially limited 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 brace 3112 for the screw rod 312 to pass through. 2 is provided with a thread, and the inner wall of the toothed sleeve 3112 is also provided with a thread that cooperates with the screw rod 312. When the lifting motor 32 drives the screw rod 312 to rotate forward or reverse, the thread on the screw rod engages with the thread on the toothed sleeve 3112 and moves relatively, so that the toothed sleeve 3112 is lifted and lowered along the axis of the screw rod 312. Since the toothed sleeve 3112 is fixedly arranged on the lifting platform 311, the lifting platform 311 is lifted and lowered 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 and lower. In other embodiments, the lifting motor 32 can also 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 gear.

[0055] Furthermore, the stirring shaft 2 is passed through the lifting platform 311, and the lifting platform 311 is provided with a bearing assembly 3113 surrounding the stirring shaft 2. In this embodiment, the first pulley 422, the synchronous belt 421, and the second pulley 423 are located on the side of the lifting platform 311 close to the upper support plate 51, the stirring shaft 2 is fixedly connected to the second pulley 423 and passes through the lifting platform 311 and the lower support plate 52 respectively, the stirring shaft 2 is synchronously lifted and lowered with the lifting platform 311, the lifting platform 311 is provided with a bearing assembly 3113, the bearing assembly 3113 is for the stirring shaft 2 to pass through so as to surround the outer periphery of the stirring shaft 2, the bearing assembly 3113 includes a bearing seat and a bearing, the bearing seat is in a groove shape and a hole-shaped structure for the stirring shaft 2 to pass through is provided at the bottom, and the groove diameter of the bearing seat is larger than the stirring shaft 2. The diameter of the mixing shaft 2 is so that the bearing can be accommodated in the groove of the bearing seat and surround the outer circumference of the mixing shaft 2. The bearing seat and the bearing cooperate with the mixing shaft 2 to enhance the stability of the mixing shaft 2 during lifting and circumferential rotation. It can be understood that in this embodiment, the transmission rod 411 is penetrated by the lifting platform 311, and the lifting platform 311 is lifted and moved along the axis of the transmission rod 411. The lifting platform 311 is also provided with a bearing assembly 3113 at the penetration position of the transmission rod 411, and the bearing assembly 3113 surrounds the outer circumference of the transmission rod 411 to improve the stability between the lifting platform 311 and the transmission rod 411 during lifting.

[0056] Furthermore, the upper support plate 51 and the lower support plate 52 are respectively provided with a lifting detection switch 54, and the lifting detection switch 54 is used to control the lifting motor 32 to be turned off. The lifting platform 311 is provided with a trigger member 3114 for triggering the lifting detection switch 54; the lifting detection switch 54 is used to control the stopping of the lifting motor 32. In the present embodiment, the trigger member 3114 is a convex block structure, and the trigger member 3114 is fixed to the lifting platform 311, and the position of the trigger member 3114 is opposite to the position of the lifting detection switch 54.
