The rear end is connected to a driving motor 5 and a speed reducer 6 that are drivingly connected to each other. The driving motor 5 is inclined and arranged on one side of the speed reducer 6. A driving shaft 7 is drivingly connected to the speed reducer 6. The driving shaft 7 penetrates through the front end of the evaporator 3 and is drivingly connected to the stirring blade 4.

[0026] In this embodiment, the driving motor 5 is inclined and arranged to reduce its occupancy rate of the longitudinal and lateral spaces of the frozen product machine. This not only facilitates the small-volume production and processing of the frozen product machine, but also because the driving motor 5 occupies less space, the frozen product machine can have enough space to increase the internal space of the material barrel 2, enabling the material barrel 2 to produce more frozen products, with strong practicability.

[0027] In addition, the driving motor 5 and the speed reducer 6 are drivingly matched by the meshing of bevel gears.

[0028] The evaporator 3 is cylindrical and horizontally arranged inside the material barrel 2. The evaporator 3, the stirring blade 4, the speed reducer 6, and the driving shaft 7 are arranged on the same axis. The axis of the driving motor 5 is inclined towards the outer side below or above the machine base 1.

[0029] In this embodiment, the axis of the driving motor 5 is inclined towards the outer side below the machine base 1, and the inclination angle between it and the horizontal line is 35 - 45 degrees.

[0030] A compressor 8 and an electronic control board 9 are arranged on the machine base 1.

[0034] In this embodiment, the carrier partition 14 is integrally arranged at the rear end of the bucket carrier 13. By using the positioning member 11 to position the inclined driving motor 5, the assembly stability of the driving motor 5 can be improved. In addition, by using the bucket support rod 12 to fix the bucket carrier 13, while improving the assembly stability of the bucket carrier 13, it can also ensure that the bucket 2 can be stably assembled.

At least part of the rear side of the bucket 2, the driving motor 5, the reducer 6, the positioning member 11, the bucket support rod 12, and the top plate support rod 19 are located in the assembly cavity.

[0039] In this embodiment, the front panel 22 is fixed on the bucket support rod 12 and the machine base 1, and the housing 23 is fixed on the top plate 21 and the machine base 1, thereby improving the assembly stability of the front panel 22 and the housing 23.

[0040] A heat dissipation group 24 is provided on the top plate support rod 19. The heat dissipation group 24 is located at the rear side of the material barrel 2 and is suspended in the assembly cavity through the top plate support rod 19.

[0042] A manual discharging assembly is provided on the material barrel 2. The manual discharging assembly includes a handle 25, a discharging nozzle 26, a squeezing member 27, and an elastic member 28. Among them, a handle connecting portion 29 is provided at the front end of the material barrel 2. The handle 25 is rotatably arranged on the material barrel 2 through the handle connecting portion 29 and is drivingly connected to the squeezing member 27 located in the discharging nozzle 26 when rotating. The discharging nozzle 26 is communicated with the material barrel 2, and the discharging port of the discharging nozzle 26 faces downward. The elastic member 28 is arranged in the discharging nozzle 26 in the direction away from the discharging port of the discharging nozzle 26 and is elastically connected to the top wall of the discharging nozzle 26 and the squeezing member 27 respectively.

[0043] When in use, the user applies a force on the handle 25 with the hand to make it rotate downward on the handle connecting portion 29. When the handle 25 rotates, it drives the squeezing member 27 to overcome the elastic force of the elastic member 28 and slide upward above the discharging nozzle 26. When the squeezing member 27 slides upward to a certain position and exceeds the communication port between the discharging nozzle 26 and the material barrel 2, the frozen product in the material barrel 2 will enter the discharging nozzle 26. At this time, the force on the handle 25 disappears (that is, the hand releases the handle 25), and the squeezing member 27 slides downward through the elastic force of the elastic member 28. At the same time, the handle 25 rotates upward to reset. When the squeezing member 27 slides downward, it will squeeze out the frozen product in the discharging nozzle 26 from the discharging port of the discharging nozzle 26.
