[0036] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model will be described in further detail in combination with the drawings. Only this declaration, the up, down, left, right, front, back, inside, outside and other orientation words appearing in the text or about to appear of the utility model are based on the drawings of the utility model, and it is not the specific limitation of the utility model.

[0037] Referring to Figure 1 And Figure 2 The utility model discloses a cold drink equipment, including refrigeration subassembly 3, rotating subassembly 4 and storage component 10, the bottom disc 51 is as the basic support structure of whole cold drink equipment, refrigeration subassembly 3 includes evaporator 31, and milk, beverage and other raw materials can heat exchange in evaporator 31, and the raw materials can be frozen into ice crystal by the heat absorption of evaporator 31, rotating subassembly 4 includes stirring drive part 41 and rotary scraper 42, rotary scraper 42 is surrounded in the periphery of evaporator 31, can push and stir the solid-liquid mixture formed in the periphery of evaporator 31 surface and raw materials, to make raw materials form smaller solid-liquid mixture of particle, wherein stirring drive part 41 is transmission connection with rotary scraper 42, and stirring drive part 41 is preferably rotary motor, variable speed DC motor and the like.

[0038] Storage component 10 includes feed cover 1 and the discharge mechanism 2 at one end of feed cover 1, feed cover 1 can accommodate the raw materials of making cold drink and the solid-liquid mixture after forming, feed cover 1 cover is in the periphery of evaporator 31, and the storage space 12 is formed between feed cover 1 and evaporator 31, and the raw materials and the solid-liquid mixture formed will move in the storage space 12, and stirring drive part 41 can drive rotary scraper 42 to rotate and stir in the storage space 12.

[0039] In order to make the formed product flow conveniently at the front end of feed cover 1, feed cover 1 further includes guide part 13, and the guide part 13 is arranged at one end of feed cover 1 close to the discharge assembly, that is, the front end of feed cover 1, under the guide action of guide part 13, the formed product can flow from the side of the discharge assembly to the upper part of feed cover 1, without affecting the product flowing from the middle of feed cover 1 to the discharge assembly, and under the continuous extrusion force, the product located at guide part 13 can continuously flow back from the upper part to the middle of feed cover 1, thereby forming a cycle. Smaller ice cream particles are prone to be retained in smaller corners, but since the inner wall of guide part 13 forms a concave surface, the concave surface is more difficult to form a storage corner than a flat surface, and thus it is more conducive to the smooth flow of ice crystal particles, and therefore the cold drink equipment of the utility model can be suitable for products such as smoothies and ice cream.

[0040] The feeding cover 11 is provided with a feeding port 111, and an extension part 16 is arranged between the outer wall of the feeding cover 11 and the feeding port 111, and is used for forming a transition connection between the feeding port 111 and the feeding cover 11. The extension part 16 gradually extends from the outer wall of the feeding cover 11 to the feeding port 111. After the raw materials are frozen to form a solid-liquid mixture, the solid-liquid mixture can be accommodated in the extension part 16 and gradually pushed forward from the extension part 16 by stirring, and the solid-liquid mixture can be pushed to the discharge port 121. The extension part 16 can increase the accommodation volume and facilitate the backflow of the solid-liquid mixture from the upper part of the feeding cover 11. The cross-sectional outer contour of the feeding cover 1 is at least partially circular or elliptical or oval, and the oval refers to a closed curved figure, a concept with a major axis and a minor axis, but there are differences in edge curvature, symmetry and the like with the standard ellipse.

[0041] The beneficial effects of the embodiment of the utility model are as follows:

[0042] The cold drink equipment of the embodiment of the utility model is provided with a refrigeration assembly 3, a rotating assembly 4 and a storage assembly. The refrigeration assembly 3 comprises an evaporator 31. The rotating assembly 4 comprises a rotating scraper 42. The storage assembly comprises a feeding cover 1. The rotating scraper 42 is arranged around the periphery of the evaporator 31 and can stir the solid-liquid mixture in the storage space 12 formed between the feeding cover 1 and the evaporator 31. During the stirring process, the solid-liquid mixture moves towards the front end of the feeding cover 1. In order to facilitate the backflow of the solid-liquid mixture at the front end, the feeding cover 1 further comprises a flow guide part 13. The flow guide part 13 is arranged at one end of the feeding cover 1 close to the discharge mechanism 2. The solid-liquid mixture can move from the front end to the upper part of the feeding cover 1 along the flow guide part 13 and backflow to the middle part of the feeding cover 1 obliquely, thereby forming backflow. Therefore, the formed cold drink product can backflow smoothly, the stirring resistance is reduced, the stirring effect is ensured, and the efficiency and stability of cold drink production are ensured.

[0043] Specifically, the flow guide part 13 gradually inclines from the upper part of the feeding cover 1 to the direction of the discharge assembly. The inner wall of the flow guide part 13 forms a concave surface. The concave surface is less likely to form a storage corner than a plane in combination with the feeding cover 1, and therefore is more conducive to the smooth flow of ice cream with smaller ice crystal particles.

[0044] Referring to Figure 2 The inner wall of the flow guide part 13 is a concave continuous curved surface. The concave continuous curved surface is adopted, so that the smooth backflow movement of the smoothie and ice cream from the position of the discharge assembly to the upper part of the feeding cover 1 is facilitated, the backflow of the solid-liquid mixture is facilitated, and the circulation of the solid-liquid mixture in the feeding cover 1 is formed.

[0045] In some embodiments, the extension 16 is an arc-shaped transition or an inclined transition. The shape of the arc-shaped transition or the inclined transition enables the solid-liquid mixture to gradually move from the position where the feed port 111 is located to the middle of the feed cover 11 and gradually move to the vicinity of the discharge port 121. Further, the surface of the extension 16 is a smooth curved surface, which can reduce the friction of the solid-liquid mixture in the extension 16, thereby facilitating the movement of the solid-liquid mixture in the extension 16, facilitating stirring and pushing, and reducing the occurrence of situations such as piling and stagnation of the solid-liquid mixture in the extension 16.

[0046] In some embodiments, the width of the extension 16 gradually increases from the outer wall of the feed cover 11 to the feed port 111, and the extension 16 forms a gradually concentrated channel away from the feed port 111, so as to facilitate the concentrated movement of the solid-liquid mixture to the middle of the feed cover 11.

[0047] In the embodiment of the utility model, the cross-sectional outer contour of the feed cover 11 is a closed contour composed of a regular or irregular smooth curve. The closed contour composed of a smooth curve can reduce the friction of the solid-liquid mixture on the inner wall of the feed cover 11, thereby reducing the occurrence of situations such as piling and stagnation, facilitating uniform stirring, and improving the stirring effect.

[0048] Referring to Figure 3 , one end of the feed cover 1 close to the discharge assembly is provided with a side end face 14, the discharge assembly is arranged on the side end face 14, and the discharge port 121 is arranged on the side end face 14. The solid-liquid mixture under extrusion will be concentrated on the side end face 14, and the upper part of the side end face 14 is connected with the lower part of the flow guide part 13. In this embodiment, the upper part of the side end face 14 is tangentially connected with the lower part of the flow guide part 13. Along the joint between the side end face 14 and the flow guide part 13, the solid-liquid mixture can smoothly transfer from the side end face 14 to the upper part of the feed cover 1, wherein the joint line between the side end face 14 and the flow guide part 13 is a first joint line 141, and the solid-liquid mixture produces a first turning in the first joint line 141, so that the solid-liquid mixture can be transferred from the side end face 14 to the upper part of the feed cover 1.

[0049] The side wall of the feeding cover 1 is provided with a barrel surface 15, which is the main body side wall of the feeding cover 1, wherein the barrel surface 15 is connected with the upper part of the flow guide part 13, and in this embodiment, the barrel surface 15 is tangentially connected with the upper part of the flow guide part 13. The solid-liquid mixture flows along the flow guide part 13 and smoothly moves to the connection position of the barrel surface 15 from the upper part of the flow guide part 13, wherein the connection line of the barrel surface 15 and the flow guide part 13 is a second connection line 151, and the solid-liquid mixture generates a second turning in the second connection line 151, so that the solid-liquid mixture can flow back to the middle part of the feeding cover 1, forming a circulation.

[0050] Referring to Figure 3 In this embodiment of the present application, the number of the second connection lines 151 is two, and the two second connection lines 151 are symmetrically and obliquely arranged from the top of the feeding cover 1 to the two sides of the flow guide part 13. The arrangement of the two second connection lines 151 can guide the movement of the solid-liquid mixture from the two symmetric sides of the flow guide part 13, and the oblique arrangement can reduce the space for the solid-liquid mixture with small ice crystal particles such as ice cream to stay in the flow guide part 13, and improve the smoothness of the backflow of the solid-liquid mixture.

[0051] Further, one end of each of the two second connection lines 151 meets the other, and the other end of each of the two second connection lines 151 extends and connects with the two ends of the first connection line 141, respectively. Along the backflow direction of the solid-liquid mixture, the two second connection lines 151 converge and meet at the upper part of the feeding cover 1 from the two ends of the first connection line 141, so that when the solid-liquid mixture moves in the flow guide part 13, it can be concentrated and gathered to the center of the upper part of the feeding cover 1 to form a concentrated backflow route. The overall cross section of the backflow solid-liquid mixture is small, and under the condition of a certain flow rate, the backflow speed of the solid-liquid mixture is improved, the backflow speed is accelerated, and the solid-liquid mixture in the stirring state can smoothly move to the side end surface 14, ensuring the backflow efficiency and the stirring effect.

[0052] Referring to Figure 2 and Figure 3 The feeding cover 1 further comprises a feeding part 11, which is arranged at one end of the feeding cover 1 away from the discharging assembly and located at the upper part of the feeding cover 1, so that the raw materials can be fully frozen and stirred after entering. The feeding port 111 is arranged on the feeding part 11, raw materials can be poured into the feeding port 111, and the cross section of the feeding port 111 gradually decreases from top to bottom. The larger feeding port 111 facilitates pouring of raw materials, and the reduced feeding port 111 also facilitates concentration of raw materials.

[0053] Referring to Figure 4The rotating scraper 42 is helical and can agitate the solid-liquid mixture by rotating, and is a direct driving component of the solid-liquid mixture. An extrusion end 421 is arranged at one end of the rotating scraper 42 close to the discharging assembly. The extrusion end 421 is the part of the rotating scraper 42 closest to the discharging assembly. In the extrusion end 421, the rotating scraper 42 is separated from the solid-liquid mixture, and the driving force for driving the solid-liquid mixture is converted into the extrusion force of the subsequent solid-liquid mixture. Referring to Figure 5 The minimum distance H between the extrusion end 421 and the side end face 14 is between 3 mm and 10 mm. For example, the minimum distance H between the extrusion end 421 and the side end face 14 includes 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, or 10 mm, but is not limited thereto. When the minimum distance between the extrusion end 421 and the side end face 14 is less than 3 mm, the solid-liquid mixture is difficult to obtain sufficient backflow space due to insufficient distance between the extrusion end 421 and the side end face 14, which affects the backflow effect. When the minimum distance between the extrusion end 421 and the side end face 14 is greater than 10 mm, the solid-liquid mixture flows slowly due to the excessive distance between the extrusion end 421 and the side end face 14, and the volume of the feeding cover 1 is increased.

[0054] Referring to Figure 6The spiral part of the rotating scraper 42 is the part for stirring the solid-liquid mixture, and is in a spiral shape as a whole, capable of stirring and pushing the solid-liquid mixture by rotation. In some embodiments, the maximum distance H2 between the outer edge of the spiral part of the rotating scraper 42 and the inner wall of the upper part of the feeding cover 11 ranges from 2 mm to 38 mm. Specifically, the maximum distance H2 between the outer edge of the spiral part of the rotating scraper 42 and the inner wall of the upper part of the feeding cover 11 includes 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, 12.5 mm, 13 mm, 13.5 mm, 14 mm, 14.5 mm, 15 mm, 15.5 mm, 16 mm, 16.5 mm, 17 mm, 17.5 mm, 18 mm, 18.5 mm, 19 mm, 19.5 mm, 20 mm, 20.5 mm, 21 mm, 21.5 mm, 22 mm, 22.5 mm, 23 mm, 23.5 mm, 24 mm, 24.5 mm, 25 mm, 25.5 mm, 26 mm, 26.5 mm, 27 mm, 27.5 mm, 28 mm, 28.5 mm, 29 mm, 29.5 mm, 30 mm, 30.5 mm, 31 mm, 31.5 mm, 32 mm, 32.5 mm, 33 mm, 33.5 mm, 34 mm, 34.5 mm, 35 mm, 35.5 mm, 36 mm, 36.5 mm, 37 mm, or 37.5 mm, but not limited thereto. When the maximum distance between the outer edge of the spiral part of the rotating scraper 42 and the inner wall of the upper part of the feeding cover 11 is less than 2 mm, the volume is small, and the rotating scraper 42 needs to maintain a certain distance from the inner wall of the upper part of the feeding cover 11 to retain as large a containing space as possible and leave space for the backflow of the solid-liquid mixture. When the maximum distance between the outer edge of the spiral part of the rotating scraper 42 and the inner wall of the upper part of the feeding cover 11 is greater than 38 mm, the volume is too large, the rotating scraper 42 cannot completely stir the solid-liquid mixture, and problems such as material accumulation and stagnation are prone to occur.

[0055] In some embodiments, the maximum distance H3 between the outer edge of the spiral portion of the rotating scraper 42 and the inner wall of the lower portion of the feed cover 11 ranges between 1.5 mm and 4 mm. Exemplarily, the maximum distance H3 between the outer edge of the spiral portion of the rotating scraper 42 and the inner wall of the lower portion of the feed cover 11 includes 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, or 4 mm, but is not limited thereto. The outer edge of the spiral portion of the rotating scraper 42 is close to the inner wall of the lower portion of the feed cover 11, and the lower portion of the feed cover 11 is prone to retaining the solid-liquid mixture due to the effect of gravity. Therefore, the distance between the inner wall of the feed cover 11 and the outer edge of the spiral portion of the rotating scraper 42 needs to be as small as possible, so that the rotating scraper 42 can scrape the solid-liquid mixture on the inner wall of the lower portion of the feed cover 11 as much as possible, thereby preventing material accumulation. When the maximum distance between the outer edge of the spiral portion of the rotating scraper 42 and the inner wall of the lower portion of the feed cover 11 is greater than 4 mm, the rotating scraper 42 cannot thoroughly stir the solid-liquid mixture in the lower portion of the feed cover 11. When the maximum distance between the outer edge of the spiral portion of the rotating scraper 42 and the inner wall of the lower portion of the feed cover 11 is less than 1.5 mm, the distance between the rotating scraper 42 and the inner wall of the feed cover 11 is too small, which affects the movement of the solid-liquid mixture and hinders the rotation of the rotating scraper 42.

[0056] In some embodiments, the maximum distance H4 between the outer edge of the spiral portion of the rotating scraper 42 and the inner wall of the left and right sides of the feed cover 11 ranges between 1.5 mm and 6 mm. Exemplarily, the maximum distance H4 between the outer edge of the spiral portion of the rotating scraper 42 and the inner wall of the left and right sides of the feed cover 11 includes 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 5 mm, 5.5 mm, or 6 mm, but is not limited thereto. Since the solid-liquid mixture on the left and right sides of the feed cover 11 moves downward under the effect of gravity, the distance between the outer edge of the spiral portion of the rotating scraper 42 and the inner wall of the left and right sides of the feed cover 11 can be appropriately large to accommodate more solid-liquid mixture. When the maximum distance between the outer edge of the spiral portion of the rotating scraper 42 and the inner wall of the left and right sides of the feed cover 11 is less than 1.5 mm, the distance between the rotating scraper 42 and the inner wall of the feed cover 11 is too small, which affects the movement of the solid-liquid mixture and hinders the rotation of the rotating scraper 42. When the maximum distance between the outer edge of the spiral portion of the rotating scraper 42 and the inner wall of the left and right sides of the feed cover 11 is greater than 6 mm, the volume is too large, the rotating scraper 42 cannot thoroughly stir the solid-liquid mixture, and material accumulation and retention are prone to occur.

[0057] In addition, the feeding cover 1 further comprises an extension 16 which protrudes upward from the surface of the barrel face 15, the feeding part 11 is provided with a feeding port 111, the cross section of the feeding port 111 gradually decreases from top to bottom so as to receive raw materials, the feeding part 11 is arranged on the extension 16, since the extension 16 protrudes upward, the position of the feeding part 11 is improved, which is more convenient for pouring raw materials, and the space for accommodating raw materials is also expanded. The extension 16 is provided with a feeding cavity 161 which is in communication with the storage space 12, when pouring raw materials, the raw materials first enter the feeding cavity 161 and then enter the storage space 12, wherein the diameter of the longitudinal section of the feeding cavity 161 is greater than the maximum diameter of the longitudinal section of the storage space 12, so that the volume of raw materials and solid-liquid mixture which can be accommodated by the feeding cover 1 is increased.

[0058] Referring to Figure 4 The rotating scraper 42 comprises a connecting ring 422, a transmission block 423 and stirring strips 424, the connecting ring 422 is arranged at one end of the rotating scraper 42 close to the stirring driving part 41 for fixing the stirring strips 424, the transmission block 423 is arranged at one end of the rotating scraper 42 close to the discharging mechanism 2, the stirring strips 424 extend from the connecting ring 422 to the transmission block 423 in a spiral shape in the circumferential direction, the number of the stirring strips 424 is at least two, the two stirring strips 424 are arranged in multiple spiral turns around each other, the stirring strips 424 can stir the solid-liquid mixture in the storage space 12 and push the solid-liquid mixture in rotation so as to concentrate the solid-liquid mixture at one end where the discharging mechanism 2 is arranged, thereby facilitating discharging. The movable end of the stirring driving part 41 is in transmission connection with the connecting ring 422 and the transmission block 423.

[0059] The traditional stirring bar 424 is a simple spiral structure, in order to be able to rotate smoothly sliding on the outer wall of the evaporator 31, a certain gap is provided between the stirring bar 424 and the evaporator 31, but the existence of such a gap will cause a layer of solid-liquid mixture on the surface of the evaporator 31 to be unable to be stirred, and then frozen on the surface of the evaporator 31, which not only cannot make the solid-liquid mixture be thoroughly stirred, but also reduces the heat exchange capacity of the surface of the evaporator 31.
