[0043] In the embodiment, the stable transmission type ice cream machine further comprises a stirring cup assembly 6 mounted outside the shell 1, the shell 1 is provided with a mounting space 11, the stirring cup assembly 6 can be detachably 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.

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.

[0044] Further, with reference to Figures 3 to 7 , 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. The first pulley 422 and the second pulley 423 are both arranged on the lifting mechanism 31. The synchronous belt 421 is sleeved with the first pulley 422 and the second pulley 423, so that the first pulley 422 and the second pulley 423 are driven by the belt. Specifically, when the stirring motor 41 is started, the stirring motor 41 drives the first pulley 422 to rotate, and the first pulley 422 drives the second pulley 423 to rotate through the synchronous belt 421, so that the synchronous belt 421 drives the second pulley 423 to rotate. The stirring shaft 2 is fixed on the second pulley 423, so that the stirring shaft 2 rotates synchronously with the second pulley 423. The first pulley 422 and the second pulley 423 are driven by the synchronous belt 421, so that the structure of the transmission mechanism 42 is simpler, the transmission is more convenient, and the noise problem during transmission is reduced.

[0045] It should be noted that the synchronous belt 421 can be a belt, the surfaces of the first pulley 422 and the second pulley 423 are provided with a plurality of grooves arranged in a circumferential direction, and the synchronous belt 421 can be additionally provided with rubber protrusions, the protrusions can be clamped into the grooves, thereby increasing the friction between the synchronous belt 421 and the first pulley 422 or the second pulley 423, and further preventing the synchronous belt 421 from slipping relative to the first pulley 422 and the second pulley 423 when transmitting power.

[0046] In the embodiment, in order to prevent the synchronous belt 421 from being disengaged from the second pulley 423 during lifting, the edges of the upper and lower sides of the second pulley 423 are provided with stop blocks 4231, and the stop blocks 4231 on the upper and lower sides form a gap between them, and the synchronous belt 421 is located in the gap between the stop blocks 4231, so that the synchronous belt 421 will not slip out of the side of the second pulley 423 and be disengaged from the second pulley 423 when driving the second pulley 423 to rotate. It can be understood that the first pulley 422 is also provided with stop blocks 4231 on the edges of the upper and lower sides to prevent the synchronous belt 421 from being disengaged from the first pulley 422. It should be noted that the stop blocks 4231 can also extend circumferentially along the edges of the second pulley 423 and be connected end to end, thereby limiting the deviation of the synchronous belt 421.

[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, and the diameter of the first pulley 422 is smaller than the diameter of the second pulley 423, so that the two pulleys can change the linear speed of the synchronous belt 421 during rotation. When the first pulley 422 is driven to rotate by the stirring motor 41, the rotating force of the first pulley 422 is transmitted to the second pulley 423 by the synchronous belt 421. When the first pulley 422 rotates, the linear speed of the synchronous belt 421 on the second pulley 423 increases, so that the rotating speed of the second pulley 423 increases, thereby increasing the rotating speed of the stirring shaft 2. Further, the diameter of the first pulley 422 is smaller than the diameter of the second pulley 423, which can change the tension and operating characteristics of the synchronous belt 421 to reduce noise and vibration in the transmission assembly 4.
