[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0032] The stirring component of the cold drink machine provided by this utility model can prevent ice from adhering to the surface of the evaporator 3 or the inner wall of the mixing cylinder 2, ensuring the heat transfer efficiency of the evaporator 3 and improving the ice-making effect of the cold drink machine.
[0033] In one specific embodiment of this utility model, the stirring component of the cold drink machine is disposed inside the mixing cylinder 2 and in contact with the surface of the evaporator 3, so that the slush or ice cream made inside the mixing cylinder 2 can be transported to the outside of the mixing cylinder 2 by the stirring component. For example... Figures 1 to 3 As shown, the stirring component of the cold drink machine includes a connector 11 and a stirring component 12. One end of the stirring component 12 is connected to the connector 11, and the other end of the stirring component 12 extends spirally in a preset direction, which is the direction in which the axis of rotation of the stirring component 12 is away from the connector 11 (e.g., ...). Figure 1 (In the X-axis direction), the connecting member 11 is used to drive the stirring member 12 to rotate. Several ice scraping parts 13 are provided at intervals on the side of the stirring member 12. The top surface of the ice scraping parts 13 protrudes from the side of the stirring member 12. The ice scraping parts 13 are used to break ice on the surface of the evaporator 3 or the inner wall of the material preparation cylinder 2.
[0034] According to the mixing component of the cold drink machine in this embodiment, by arranging a plurality of ice scraping parts 13 on the side of the mixing component 12, and making the top surface of the ice scraping parts 13 protrude from the side of the mixing component 12, the mixing component 12 can drive the plurality of ice scraping parts 13 to move relative to the surface of the evaporator 3 or the inner wall of the material preparation cylinder 2 when the connecting component 11 drives the mixing component 12 to rotate. This physically destroys the ice layer attached to the surface of the evaporator 3 or the inner wall of the material preparation cylinder 2, effectively preventing the ice layer from adhering to the surface of the evaporator 3 or the inner wall of the material preparation cylinder 2, thus hindering the heat exchange between the evaporator 3 and the ice-making raw materials in the material preparation cylinder 2. This effectively ensures the heat transfer efficiency of the evaporator 3, improves the ice-making effect of the cold drink machine, and ensures that the cold drink machine can continuously and stably provide cold drinks such as shaved ice or ice cream.
[0035] In addition, the top surface of the ice scraper 13 protruding from the side of the agitator 12 breaks the ice layer attached to the surface of the evaporator 3 or the inner wall of the feeding cylinder 2, which not only ensures the ice breaking efficiency, but also reduces the contact area between the side of the agitator 12 and the surface of the evaporator 3 or the inner wall of the feeding cylinder 2, thereby reducing the friction force on the side of the agitator 12 and ensuring the rotation efficiency of the agitator 12.
[0036] Specifically, in the existing cold drink machine, when arranging the relative positions of the mixing cylinder 2 and the evaporator 3, the mixing cylinder 2 can be placed inside the evaporator 3, or the evaporator 3 can be placed inside the mixing cylinder 2, depending on the actual layout requirements. Corresponding to the relative positions of the mixing cylinder 2 and the evaporator 3, the ice scraper 13 in the stirring component 12 can have the following two positional relationships:
[0037] The first type of positional relationship, such as Figure 1 and Figure 4As shown, when the evaporator 3 is placed inside the feed cylinder 2, the stirring element 12 is sleeved on the outer side of the evaporator 3, and the ice scraping part 13 is formed on the inner side of the stirring element 12. When the stirring element 12 drives several ice scraping parts 13 to rotate relative to the evaporator 3, several ice scraping parts 13 can contact the outer side of the evaporator 3 to break the ice on the outer side of the evaporator 3, avoid the ice layer from adhering to the outer side of the evaporator 3, and ensure the heat exchange efficiency between the ice-making raw material and the evaporator 3.
[0038] The second type of positional relationship, such as Figure 5 and Figure 6 As shown, when the feeding cylinder 2 is located inside the evaporator 3, the stirring element 12 is connected to the inner side of the feeding cylinder 2, and the ice scraping part 13 is formed on the outer side of the stirring element 12. When the stirring element 12 drives several ice scraping parts 13 to rotate relative to the feeding cylinder 2, several ice scraping parts 13 can contact the inner side of the feeding cylinder 2 to break the ice on the inner side of the feeding cylinder 2, avoid the ice layer from adhering to the inner side of the feeding cylinder 2, and ensure the heat exchange efficiency between the ice-making raw material and the evaporator 3.
[0039] In this embodiment, as Figure 2 and Figure 3 As shown, the top surface of the ice scraper 13 is either flat or curved to increase the contact area between the ice scraper 13 and the inner side of the mixing cylinder 2 or the outer side of the evaporator 3, thereby reducing localized wear and improving the wear resistance of the ice scraper 13. Preferably, the top surface of the ice scraper 13 is formed into a streamlined curved surface, so that the ice scraper 13 can better adapt to the fluid dynamics characteristics of slushies or ice creams and reduce fluid resistance.
[0040] Furthermore, the ice scraper 13 is connected to the side arc of the stirring member 12, thereby preventing the ice scraper 13 from forming scratches on the outer side of the evaporator 3 or the inner side of the material making cylinder 2 when the stirring member 12 drives the ice scraper 13 to rotate, which would damage the heat exchange surface between the evaporator 3 and the ice making raw material, thus ensuring the heat exchange efficiency between the evaporator 3 and the ice making raw material, while avoiding obstruction to the flow of the ice making raw material or shaved ice and ice cream.
[0041] In this embodiment, a preset gap is formed between the top surface of the ice scraper 13 and the outer side of the evaporator 3, or between the top surface of the ice scraper 13 and the inner side of the mixing cylinder 2. The preset gap is 0.05mm-0.4mm, so as to ensure that the ice scraper 13 can be used to break the ice while avoiding the rotation of the stirring member 12 being hindered by the outer side of the evaporator 3 or the inner side of the mixing cylinder 2, which would affect the conveying efficiency of the stirring member 12 to ice cream or shaved ice.
[0042] When the stirring element 12 is fitted onto the outer side of the evaporator 3, i.e., when the evaporator 3 is inside the mixing cylinder 2, to prevent slush or ice cream from accumulating on the inner wall of the mixing cylinder 2, such as... Figure 7As shown, a first gap d1 is formed between the outer edge of the agitator 12 and the side wall of the mixing cylinder 2, wherein the first gap d1 is 1.5mm-6mm; a second gap d2 is formed between the outer edge of the agitator 12 and the bottom wall of the mixing cylinder 2, wherein the second gap d2 is 1.5mm-4mm. This is to use the outer edge of the agitator 12 to agitate the slush or ice cream that is in contact with the inner wall of the mixing cylinder 2, and to push the slush or ice cream that is in contact with the inner wall of the mixing cylinder 2 back into the ice-making cavity inside the mixing cylinder 2, so as to avoid material accumulation on the inner wall of the mixing cylinder 2, and at the same time ensure that the agitator 12 agitates the slush or ice cream more evenly.
[0043] Preferably, the first spacing d1 is 1.9 mm and the second spacing d2 is 1.6 mm, so as to shorten the distance between the outer edge of the stirring component 12 and the inner wall of the mixing cylinder 2 without affecting the rotation of the stirring component 12, thereby improving the stirring effect of the stirring component 12 on the slush or ice cream in contact with the inner wall of the mixing cylinder 2.
[0044] Of course, in some other embodiments, the first spacing d1 can also be 1.5mm, 2mm, 3mm, 4mm, 5mm and 6mm, but is not limited to this, and can be designed according to actual needs; the second spacing d2 can also be 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm and 4mm, but is not limited to this, and can be designed according to actual needs, so as to avoid material accumulation on the inner side wall of the material preparation cylinder 2, and at the same time ensure that the rotation and stirring of the stirring component 12 are not affected.
[0045] A third gap d3 is formed between the outer edge of the mixing element 12 and the top wall of the mixing cylinder 2, wherein the third gap d3 is 2mm-38mm, so as to form a reflux space between the top of the mixing element 12 and the top wall of the mixing cylinder 2, so as to facilitate the reflux of the made smoothie or ice cream into the interior of the mixing cylinder 2. At the same time, it ensures that the mixing element 12 can push the smoothie or ice cream on the top wall of the mixing cylinder 2 and the top of the mixing element 12, thereby preventing the smoothie or ice cream in contact with the top wall of the mixing cylinder 2 from being stuck on the top of the mixing cylinder 2, and further improving the uniformity of mixing the smoothie or ice cream.
[0046] In some embodiments, the third spacing d3 can be 2mm, 10mm, 15mm, 20mm, 25mm, 30mm, or 38mm, but is not limited to these. It can be designed according to actual needs to provide a reflux space for smoothies or ice cream, while the stirring element 12 can push the smoothies or ice cream at the top of the mixing cylinder 2.
[0047] In this embodiment, as Figure 1 and Figure 2As shown, the connector 11 has a connecting seat 14, one end of the stirring member 12 is connected to the connecting seat 14, and the connecting seat 14 has a driving hole 141. The rotation axis of the stirring member 12 coincides with the axis of the driving hole 141. Specifically, the driving hole 141 can be connected to the output shaft of the drive motor, so that the driving motor can rotate forward or reverse to drive the stirring member 12 to rotate forward or reverse, thereby conveying the ice cream or slush obtained after ice making to the outside of the mixing cylinder 2 for user use. Since the rotation axis of the stirring member 12 coincides with the axis of the driving hole 141, it can be ensured that the stirring member 12 rotates around the output shaft of the drive motor, thereby ensuring that the ice-breaking part of the stirring member 12 can evenly contact the outer side of the evaporator 3 or the inner side of the mixing cylinder 2, effectively improving the uniformity of ice breaking on the outer side of the evaporator 3 or the inner side of the mixing cylinder 2.
[0048] Furthermore, such as Figure 1 and Figure 2 As shown, the mixing component of the cold drink machine also includes a connecting plate 15. The end of the mixing element 12 away from the connecting seat 14 is connected to the connecting plate 15. The center of the inner side of the connecting plate 15 coincides with the axis of the drive hole 141 to ensure that the end of the mixing element 12 away from the connecting seat 14 can rotate with the output shaft of the drive motor as the rotation center. This prevents the end of the mixing element 12 away from the connecting seat 14 from being subjected to centrifugal force during rotation and moving away from the outer side of the evaporator 3 or close to the inner side of the material preparation cylinder 2, thus ensuring the uniformity of ice breaking of the outer side of the evaporator 3 or the inner side of the material preparation cylinder 2 by the ice scraping part 13 in the mixing element 12.
[0049] Furthermore, such as Figure 1 and Figure 2 As shown, the mixing component of the cold drink machine also includes a support bar 16. The mixing component 12 includes at least two spiral blades 121, and the at least two spiral blades 121 are connected by the support bar 16 to improve the connection stability of the spiral blades 121. When the agitator 12 uses the ice scraper 13 to break ice on the outer side of the evaporator 3, the inner side of the support bar 16 is flush with the inner side of the spiral blade 121. When the spiral blade 121 rotates, the support bar 16 rotates around the rotation axis of the spiral blade 121 to prevent the middle part of the agitator 12 from being affected by centrifugal force and moving away from the outer side of the evaporator 3, thus further ensuring the uniformity of ice breaking on the outer side of the evaporator 3. Similarly, when the agitator 12 uses the ice scraper 13 to break ice on the inner side of the feeding cylinder 2, the outer side of the support bar 16 is flush with the outer side of the spiral blade 121, so that the support bar 16 rotates around the rotation axis of the spiral blade 121 to prevent the middle part of the agitator 12 from approaching the inner side of the feeding cylinder 2, thus ensuring the uniformity of ice breaking on the inner side of the feeding cylinder 2.
[0050] In this embodiment, as Figure 1As shown, the mixing component of the cold drink machine also includes a discharge blade 17, which is disposed on the connector 11. The end of the discharge blade 17 facing the mixing component 12 is connected to the mixing component 12, so that with the cooperation of the mixing component 12 and the discharge blade 17, the slush or ice cream in the mixing cylinder 2 can be discharged from the end of the discharge blade 17 away from the mixing component 12 to the outside of the mixing cylinder 2. The end of the discharge blade 17 away from the mixing component 12 protrudes outward from the connector 11, and the end of the discharge blade 17 away from the mixing component 12 forms a discharge end face 171. A preset distance is formed between the discharge end face 171 and the connector 11, which is greater than the length of the connector 11, so that the slush or ice cream can stay briefly in the space between the discharge end face 171 and the connector 11, and be further stirred by the discharge blade 17 to further improve the uniformity of the output slush or ice cream.
[0051] Accordingly, this utility model also provides a cold drink machine, which includes the stirring component described in any of the above embodiments, wherein the cold drink machine is a smoothie maker, an ice cream maker, or a multi-functional smoothie / ice cream maker. Using the cold drink machine of this embodiment can prevent ice from adhering to the side of the evaporator 3 or the side of the mixing cylinder 2, ensuring the heat transfer efficiency of the evaporator 3 and improving the ice-making effect of the cold drink machine. At the same time, the cold drink machine possesses all the beneficial effects of the aforementioned stirring component, which will not be elaborated further here.
[0052] In this embodiment, the cold drink machine is a smoothie maker, an ice cream maker, or a multi-functional smoothie / ice cream maker, and the corresponding functions can be set for the cold drink machine according to actual needs.
[0053] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
