[0038] The cup cover 3 is detachably covered on the outer cup 1 and closes the first containing cavity 11.

[0039] The embodiment solves the problems of difficult installation and alignment of the inner cup 2 and the outer cup 1 of the ice cream machine and the self-rotation of raw materials during stirring. The first positioning member 12 is arranged on the inner side wall of the first accommodating cavity 11 of the outer cup 1, and the second positioning member 22 is arranged on the outer side wall of the inner cup 2, so that the first positioning member 12 and the second positioning member 22 are clamped together, and the outer cup 1 and the inner cup 2 are circumferentially positioned. Since the first positioning member 12 and the second positioning member 22 are arranged on the side surfaces of the outer cup 1 and the inner cup 2 respectively, when the inner cup 2 enters the first accommodating cavity 11, the user can observe the alignment downward, and there is no structure on the inner cup 2 and the outer cup 1 to block the line of sight, so the user can clearly observe the clamping position of the first positioning member 12 and the second positioning member 22, thereby accurately and quickly fixing the inner cup 2. The anti-rotation member 23 is arranged at the bottom of the inner cup 2 to block the self-rotation of the stirring material in the inner cup 2, so that the ice cream material can be more fully stirred. Specifically, the outer cup 1 and the inner cup 2 are both cylindrical structures, and the first accommodating cavity 11 and the second accommodating cavity 21 are also cylindrical cavities. During use, the material to be stirred is placed in the second accommodating cavity 21, the inner cup 2 enters the first accommodating cavity 11 along the vertical direction, the first positioning member 12 and the second positioning member 22 are clamped together, the inner cup 2 and the outer cup 1 are relatively positioned along the circumference, the cup cover 3 is covered on the outer cup 1, the cup cover 3 seals the first accommodating cavity 11 and the second accommodating cavity 21, and the cup cover 3 limits the inner cup 2 from separating from the first accommodating cavity 11 along the vertical direction, so that the stirring material can complete the stirring in the second accommodating cavity 21.

[0040] In the embodiment, the anti-rotation member 23 is arranged at the bottom of the second accommodating cavity 21, the stirring material has viscosity, when the ice cream stirring material is placed in the second accommodating cavity 21, the external stirring device extends into the second accommodating cavity 21 and stirs the ice cream stirring material, the stirring material is subjected to the circumferential stirring force, the anti-rotation member 23 is in contact with the stirring material, and the anti-rotation member 23 applies resistance to the stirring material to prevent the stirring material from being bonded to the external stirring device and rotating with the external stirring device, so that the stirring material does not rotate in the second accommodating cavity 21, and the stirring material can be fully stirred and fused. Further, the first positioning member 12 is a positioning protrusion 121, and the second positioning member 22 is a positioning groove 221, and the lower end of the positioning groove 221 is open to allow the positioning protrusion 121 to be clamped in. In the embodiment, the first positioning member 12 is the positioning protrusion 121 protruding from the side wall of the first accommodating cavity 11, and the second positioning member 22 is the positioning groove 221 recessed along the outer side wall of the inner cup 2, when the inner cup 2 enters the first accommodating cavity 11, the user observes the relative positions of the positioning protrusion 121 and the positioning groove 221 through the space between the outer wall of the inner cup 2 and the cavity wall of the first accommodating cavity 11, and aligns the positioning protrusion 121 with the positioning groove 221 by rotating the inner cup 2, the lower end of the positioning groove 221 is open, so that the positioning protrusion 121 can enter the positioning groove 221 through the opening at the lower end of the positioning groove 221, and the positioning protrusion 121 is clamped in the positioning groove 221, so that the inner cup 2 cannot rotate relative to the outer cup 1. It should be noted that in other embodiments, the first positioning member 12 and the second positioning member 22 can also be both stop blocks, the cavity wall of the first accommodating cavity 11 is provided with two spaced stop blocks, and the outer wall of the inner cup 2 is provided with one stop block, when the inner cup 2 enters the first accommodating cavity 11, the stop block on the inner cup 2 is clamped between the two stop blocks of the first accommodating cavity 11, thereby limiting the rotation of the inner cup 2 relative to the outer cup 1.

[0041] Further, the number of the positioning protrusions 121 is set to be multiple, and the multiple positioning protrusions 121 are arranged at equal intervals in the circumferential direction of the side wall of the first accommodating cavity 11. In the embodiment, the positioning protrusions 121 are arranged in multiple at the cavity wall of the first accommodating cavity 11, and the multiple positioning protrusions 121 are arranged at intervals, and the positioning grooves 221 are also arranged in multiple at the outer side wall of the inner cup 2, and when the inner cup 2 is accommodated in the first accommodating cavity 11, the positions of the multiple positioning grooves 221 correspond to the positions of the multiple positioning protrusions 121, in the embodiment, the positioning protrusions 121 are arranged in four, and the positioning grooves 221 are arranged in four, and each positioning protrusion 121 can be clamped in the corresponding positioning groove 221, so that the positioning of the inner cup 2 relative to the outer cup 1 is more firm, and it can be understood that the positioning protrusions 121 and the positioning grooves 221 can also be arranged in two or three.

[0042] Further, the two adjacent positioning protrusions 121 are arranged at equal intervals in the circumferential direction, so that after the inner cup 2 enters the first accommodating cavity 11, only one of the positioning protrusions 121 is required to be positioned opposite the positioning groove 221, and the remaining positioning protrusions 121 are simultaneously positioned opposite the positioning groove 221, so that the user is more convenient when installing the inner cup 2. In this embodiment, the groove wall of the positioning groove 221 is an arc surface, and the side of the positioning protrusion 121 away from the side wall of the first accommodating cavity 11 is inserted into the positioning groove 221 and also has an arc surface, so that when the positioning protrusion 121 is inserted into the positioning groove 221, the arc side surface on the positioning protrusion 121 and the arc groove wall on the positioning groove 221 are mutually fitted, so that the inner cup 2 does not shake left and right in the first accommodating cavity 11 and is more stable. Part of the structure of the positioning protrusion 121 is inserted into the positioning groove 221, and another part is exposed from the positioning groove 221, so that there is a space between the outer side wall of the inner cup 2 and the side wall of the first accommodating cavity 11 for the user to observe. In addition, in the direction from the side wall of the first accommodating groove to the center thereof, the width of the positioning protrusion 121 gradually decreases.

[0043] Further, a gap for observing the positioning protrusion 121 is arranged between the outer wall of the inner cup 2 and the cavity wall of the first accommodating cavity 11. The radial distance of the inner cup 2 is less than the radial distance of the first accommodating cavity 11, so that after the inner cup 2 is accommodated in the first accommodating cavity 11, there is a space between the outer side of the inner cup 2 and the side wall of the first accommodating cavity 11 for the user to observe, so that the user can clearly observe the position of the positioning protrusion 121 on the side wall of the first accommodating cavity 11 when installing the inner cup 2, which is convenient, fast and accurate.

[0044] Further, the anti-rotation member 23 is an anti-rotation stop groove 231, which is recessed downward along the bottom wall of the second accommodating cavity 21. In this embodiment, the anti-rotation member 23 is a groove-shaped anti-rotation stop groove 231, which is located at the bottom of the second accommodating cavity 21. The anti-rotation stop groove 231 can block the self-rotation of the stirring material in the second accommodating cavity 21. When the ice cream stirring material is placed in the second accommodating cavity 21, part of the stirring material enters the anti-rotation stop groove 231. The external stirring device stirs the stirring material, and the groove wall of the anti-rotation stop groove 231 blocks part of the stirring material in the stirring direction, so that the stirring material does not stick to the stirring device and rotate synchronously, so that the stirring material can be fully stirred and mixed. It should be noted that the anti-rotation member 23 is arranged in a groove shape, which can prevent the external stirring device from colliding with the anti-rotation member 23 during stirring. The external stirring device can be a knife, so that the stirring device can be inserted into the bottom of the second accommodating cavity 21 for stirring to ensure that the stirring material is fully mixed. Of course, it can be understood that the anti-rotation member 23 can also be a column structure fixed at the bottom of the second accommodating cavity 21 without affecting the stirring.

[0045] Further, the bottom wall of the anti-rotation blocking groove 231 is inclined, and in the stirring direction of the stirring material, the one end of the anti-rotation blocking groove 231 gradually recesses downward to the other end. In this embodiment, the bottom groove wall of the anti-rotation blocking groove 231 is an inclined slope, and in the circumferential stirring direction of the stirring material, the one end of the anti-rotation blocking groove 231 is provided as a first end, and the other end is provided as a second end. The bottom groove wall of the first end of the anti-rotation blocking groove 231 is smoothly connected with the bottom groove wall of the first containing cavity 11, and in the process from the first end to the second end of the anti-rotation blocking groove 231, the bottom groove wall of the anti-rotation blocking groove 231 gradually extends downwardly and obliquely, so that the depth of the first end of the anti-rotation blocking groove 231 is smaller than the depth of the second end of the anti-rotation blocking groove 231, so that the stirring material can easily enter the anti-rotation blocking groove 231 when being stirred, and the blocking effect of the anti-rotation blocking groove 231 is better.

[0046] Further, the anti-rotation blocking groove 231 is provided in plurality, and the plurality of anti-rotation blocking grooves 231 are arranged in the circumferential direction on the bottom wall of the second containing groove. In this embodiment, the plurality of anti-rotation blocking grooves 231 are arranged in the circumferential direction on the bottom wall of the second containing cavity 21, and in the adjacent two anti-rotation blocking grooves 231, the second end of the former anti-rotation blocking groove 231 is close to the first end of the other anti-rotation blocking groove 231, so that the stirring material can enter each anti-rotation blocking groove 231 in the circumferential stirring direction, so as to increase the anti-rotation effect.

[0047] Further, the outer wall of the inner cup 2 is provided with a frost prevention rib 24, and the frost prevention rib 24 is arranged in the circumferential direction on the outer wall of the inner cup 2. In this embodiment, the frost prevention rib 24 is a strip-shaped convex rib protruding on the outer wall of the inner cup 2, and the plurality of frost prevention ribs 24 are arranged in the circumferential direction on the outer wall of the inner cup 2, so that the outer wall of the inner cup 2 forms a frost prevention layer composed of a ring of frost prevention ribs 24. The frost prevention rib 24 can be made of a temperature insulation material. Since the temperature in the inner cup 2 is very low when making ice cream, the temperature of the outer wall of the inner cup 2 is relatively low when the inner cup 2 is taken out of the first containing cavity 11, and long-time contact with the outer wall of the inner cup 2 can easily cause the user's fingers to be frozen. By arranging a ring of frost prevention ribs 24 on the outer wall of the inner cup 2, the user's fingers can not directly contact the outer wall of the inner cup 2, thereby ensuring the safety and comfort of the user during use.

[0048] Further, the outer cup 1 is provided with a clamping block 13 at the opening edge of the first accommodating cavity 11, and the inner side of the edge of the cup cover 3 is correspondingly provided with a clamping groove 31, the clamping block 13 is clamped into the clamping groove 31, and the cup cover 3 covers the outer cup 1 and the inner cup 2. The cup cover 3 is buckled with the outer cup 1, so that the cup cover 3 is fixed relative to the outer cup 1 and presses the inner cup 2 downward, preventing the inner cup 2 from being separated upward from the first accommodating cavity 11, and the cup cover 3 simultaneously seals the first accommodating cavity 11 and the second accommodating cavity 21, so that the stirring material in the second accommodating cavity 21 cannot overflow during stirring. In the embodiment, the clamping block 13 is protrudingly arranged at the edge of the outer cup 1, one side of the cup cover 3 is formed with a covering space for accommodating an external stirring device such as a stirring tool, the clamping groove 31 is located at the edge of the cup cover 3, and the cup cover 3 is further provided with an inclined guide slope at the position of the clamping groove 31, so as to guide the clamping block 13 to be clamped into the clamping groove 31. When the cup cover 3 needs to be covered, the cup cover 3 is buckled at the opening of the first accommodating cavity 11 of the outer cup 1, the cup cover 3 is circumferentially rotated, the clamping block 13 is slid along the inclined guide slope and clamped into the clamping groove 31, and the cup cover 3 is moved downward, so as to tightly seal the first accommodating cavity 11 and the second accommodating cavity 21. It can be understood that the covering and sealing mode of the cup cover 3 relative to the first accommodating cavity 11 and the second accommodating cavity 21 is not limited, and the cup cover 3 can be in a form of a lock, a thread or a swing buckle.

[0049] An embodiment of the utility model further proposes a kind of ice cream machine, including above-mentioned cup body assembly, further include machine body 4 and stirring shaft component 5, the outer cup 1 is fixed in the machine body 4, the stirring shaft component 5 is elevated relative to the machine body 4, to stretch into the inner cup 2 and stirs the stirring material.
