Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to an ice cream device. Background Art

[0002] Ice cream is a beloved summer dessert. Commercially available ice cream is typically prepared by mixing and stirring ingredients like milk, egg yolks, and sugar. The mixture is then poured into a freezer bucket and stirred until soft. Once frozen, it's placed in the freezer until hard. Before serving, the ice cream can be taken out and placed under a warmer to soften slightly, making it easier to scoop. There are also shaved ice cream machines available on the market. These use fresh fruit or milk as the base, freeze it in the freezer until hard, and then use a rotating shaver to shred the frozen ingredients layer by layer. However, this method doesn't allow for complete slicing of the ingredients. Utility Model Content

Using the above solution, the rotating shaft 2111 directly drives the tool 20 to rotate; the nut 2122, through a threaded connection with the screw 2121, reduces the output speed and drives the tool 20 to move up and down; thus, the tool 20 can achieve high-speed and stable rotation while having a low vertical lifting speed. In some embodiments, the cutter 20 includes a sleeve 201 and an ice-shaved blade 202 provided on the sleeve 201; the screw 2121 is provided with a cutter shaft 213, and the top end of the rotating shaft 2111 can extend the screw 2121 and connect with the cutter shaft 213 to drive the cutter shaft 213 to rotate; the bottom end of the cutter shaft 213 is connected to the nut 2122, so that the cutter shaft 213 can move up and down while rotating; wherein, the sleeve 201 is sleeved on the outside of the cutter shaft 213, so that the cutter shaft 213 can drive the sleeve 201 to move synchronously. In some embodiments, the top end of the rotating shaft 2111 is connected to a connecting piece 2111a, and the connecting piece 2111a and the knife shaft 213 are flatly matched to achieve synchronous movement between the connecting piece 2111a and the knife shaft 213, thereby achieving synchronous movement of the rotating shaft 2111 and the knife shaft 213; the bottom end of the knife shaft 213 is connected to the nut 2122 through a screw, so that the screw 2121 can drive the nut 2122 to rise or fall when rotating forward or reverse, thereby achieving synchronous rise or fall of the knife shaft 213.

In some embodiments, the trigger portion 214 is formed by the outer wall of the nut 2122 extending radially outward. When the blade shaft assembly 21 rises to the point where the top end of the trigger portion 214 abuts against the upper limit switch 11, the blade shaft assembly 21 stops ascending, and the tool 20 is now extended to the maximum extent from the tool holder 23.
