In their structural designs, in order to cooperate with the crushing and whipping of the mixing blade in the food processor, turbulator ribs are convexly provided on the inner wall of the mixing cup of the food processor. In the existing structure, the turbulator ribs can play a certain role in generating turbulence, but the improvement of the crushing and whipping effect on food ingredients is still limited. Summary of the Invention

[0004] The main object of the present invention is to provide a mixing cup, aiming to improve the whipping and crushing effect of food ingredients in a food processor.

[0005] To achieve the above object, the mixing cup proposed by the present invention is applied to a food processor. The mixing cup includes a cup body, and turbulator ribs are convexly provided on the inner wall surface of the cup body.

Thus, when the mixing cup of the present application is in operation, the fluid rushes towards the inner wall of the mixing cup due to the agitation of the mixing blade and the centrifugal force in the food processor. Then, during the flow along the inner wall of the mixing cup, it contacts the first turbulator surface and the second turbulator surface. Since at least one of the first turbulator surface and the second turbulator surface is a curved surface that is concave towards the inside of the turbulator ribs, through the guiding action of this curved surface, the fluid can be driven to rush towards the middle of the mixing cup along the curved surface, and then fully collide with the mixing blade, so that the food ingredients are further crushed and whipped, and thus the obtained food ingredients are finer.

[0040] The present invention provides a mixing cup 100.

[0041] Please refer to Figure 1 and Figure 2, The mixing cup 100 is used in a food processor. During use, the mixing blade 240 in the food processor beats the ingredients in the mixing cup 100. The mixing cup 100 includes a cup body 110, a handle 120 installed outside the cup body 110. The inner wall surface of the cup body 110 is convexly provided with turbulence ribs 130. The turbulence ribs 130 at least include a first turbulence surface 131 and a second turbulence surface 132 distributed on both sides of the turbulence ribs 130. Among them, at least one of the first turbulence surface 131 and the second turbulence surface 132 is formed into a curved surface that is recessed towards the turbulence ribs 130 and / or the inner wall surface of the cup body 110. The curved surface is used to guide the fluid of the ingredients towards the middle of the mixing cup 100 during the beating process.

[0042] In the embodiment of the present application, the cup body 110 is a cylindrical shape with openings at both the top and bottom. Among them, the cup body 110 can be made of metal, plastic, glass or other materials. The present application does not make specific restrictions on the material of the cup body 110, as long as its material meets the structural strength and hygienic safety performance. The turbulence ribs 130 can be an integral structure with the cup body 110, for example, obtained by integral casting. Of course, the turbulence ribs 130 can also be a split structure with the cup body 110 and are fixed to the cup body 110 by means such as clamping and welding. Considering structural strength and manufacturing, the present application preferably adopts the form of an integral structure of the turbulence ribs 130 and the cup body 110. In particular, the turbulence ribs 130 can be formed by the inward depression of the side wall of the cup body 110 to form the turbulence ribs 130, which can further save materials and reduce the weight of the entire mixing cup 100. During actual use, the mixing cup 100 and other components in the food processor form a mixing cavity. Among them, the mixing blade 240 in the food processor can extend into the mixing cavity from the bottom of the mixing cup 100 or from the top of the mixing cup 100. That is, an installation structure can be provided at the bottom of the cup body 110 to cooperate and fix with parts such as the mixing blade 240 in the food processor, or an installation structure can be provided at the top of the cup body 110 to cooperate and fix with parts such as the mixing blade 240 in the food processor.

[0043] To improve the mixing effect, at least two turbulence ribs 130 can be provided on the inner wall surface of the cup body 110 of the present application. The at least two turbulence ribs 130 are arranged at intervals in the circumferential direction of the mixing cup 100. In the scheme shown in the drawings, 4 turbulence ribs 130 are arranged at intervals in the circumferential direction on the inner wall surface of the cup body 110. Each of the turbulence ribs 130 maintains a basically the same shape and is arranged in a long strip shape extending in the axial direction of the cup body 110. It can be understood that the number of the turbulence ribs 130 in the present application can be, in addition to the 4 shown in the drawings, for example, 3, 5, 6, etc. The present application does not make any restrictions on this either.

[0044] Further, the first spoiler surface 131 and the second spoiler surface 132 are distributed on both sides of the spoiler rib 130, that is, the first spoiler surface 131 and the second spoiler surface 132 are on both sides of the spoiler rib 130 in the circumferential direction of the cup body 110, and both the first spoiler surface 131 and the second spoiler surface 132 extend in the axial direction of the cup body 110. Among them, the first spoiler surface 131 and the second spoiler surface 132 intersect at the middle of the spoiler rib 130 and are smoothly transitioned. The intersection of the first spoiler surface 131 and the second spoiler surface 132 forms the top of the spoiler rib 130. In this application, the surface is recessed into the spoiler rib 130, and this surface is recessed from the surface from the root connected to the inner wall surface of the spoiler rib 130 and the cup body 110 to the top. At the same time, it can be understood that at least one of the first spoiler surface 131 and the second spoiler surface 132 forms a surface recessed towards the spoiler rib 130 and / or the inner wall surface of the cup body 110. There can be three cases. One case is that only the first spoiler surface 131 forms a curved surface. In this case, from the perspective of the attached drawing, when the stirring blade 240 rotates at the clockwise angle indicated by the arrow in the figure, when the food fluid in the stirring cup 100 impacts the curved surface formed by the first spoiler surface 131, due to the guiding effect of this surface, the food fluid can be guided to the middle of the stirring cup 100, and then the fluid material can be fully collided and contacted with the stirring blade 240 again, so that the food fluid is fully whipped and cut, and the obtained food is finer. Specifically, in the rotation direction of the stirring blade 240, one end of the curved surface connected to the inner wall surface of the cup body 100 gradually extends towards the inside of the cup body 100 from the other end away from the inner wall surface of the cup body 100. From another perspective, the connection line from one end of the curved surface connected to the inner wall surface of the cup body 100 to the other end away from the inner wall surface of the cup body 100 does not coincide with the radial direction of the cup body 100. And in a preferred setting form, the included angle formed between this connection line and the tangential direction of the cup body 100 at the position where the spoiler rib 130 is located is an acute angle, and the angle can be 30 degrees to 70 degrees. Thus, under the drive of the stirring blade 240, when the fluid food flows along the inner wall surface of the cup body 100 and moves to the position of the spoiler rib 130, it will be gradually guided to the middle of the stirring cup 100 along the curved surface and then collide with the stirring blade 240 again. Further, in this application, the curved surface is also smoothly transitioned with the inner wall surface of the cup body 100. Therefore, in the above guiding process, when the fluid food transitions from the inner wall surface of the cup body 100 to the curved surface, due to the smooth transition setting, there will be no turbulent vortex phenomenon, and thus the fluid food can be efficiently guided to the cup body 100. In another case, it can be that the second spoiler surface 132 forms a curved surface. The principle of this case is similar to the first case. At this time, the stirring blade 240 runs in the counterclockwise direction in the figure.In the third case, both the first spoiler surface 131 and the second spoiler surface 132 are formed as curved surfaces. In the third case, the mixing cup 100 can be applied to the clockwise rotation mode, counterclockwise rotation mode, and clockwise and counterclockwise alternating rotation mode in a food processor. In this way, the applicability is wider, and it can cooperate with various operating modes of the food processor at the same time to obtain better whipping effects.

[0045] In summary, in the technical solution of the present invention, in the structure of the mixing cup 100, at least one of the first spoiler surface 131 and the second spoiler surface 132 on the spoiler rib 130 of its inner wall is formed as a curved surface that is recessed into the spoiler rib 130. Thus, during the operation of the mixing cup 100 of the present application, the fluid rushes towards the inner wall of the mixing cup 100 due to the agitation of the mixing blade 240 and the centrifugal force in the food processor. Then, during the flow along the inner wall of the mixing cup 100, it contacts the first spoiler surface 131 and the second spoiler surface 132. Since at least one of the first spoiler surface 131 and the second spoiler surface 132 is a curved surface that is recessed into the spoiler rib 130, through the guiding action of this curved surface, the fluid can be driven to rush towards the middle of the mixing cup 100 along the curved surface, and then collide with the mixing blade 240 more fully, so that the ingredients are further crushed and whipped, and thus the obtained ingredients are more delicate.

[0046] Combined with the above content, the solution of the present application forms at least one of the first spoiler surface 131 and the second spoiler surface 132 in the spoiler rib 130 as a curved surface that is recessed into the spoiler rib 130, so that the food ingredient fluid can be guided to the middle of the cup body 110 during the whipping process. In order to make the whipping effect more excellent in this process, in one embodiment, the contour line obtained by the intersection of the curved surface and the horizontal cross-section is a section of a spiral line. We can understand that the spiral line has a smoothly transitioning configuration. Thus, during the operation of the food ingredient fluid along this curved surface from the root to the top of the spoiler rib 130, the flow direction gradually changes, and then it is guided to the mixing blade 240 in the middle of the mixing cup 100 and collides with the mixing blade 240 more fully again. The flow direction of the food ingredient fluid changes gently throughout the process, and the impact on the mixing cup 100 is small, which is beneficial to the stability during the operation of the overall structure.

[0047] Please refer to Figure 3In one embodiment, the spiral is an involute. Since the normal of each point on the involute is necessarily tangent to the base circle, and the normal is directed to the inside of the cup body 110, when the food fluid flows along the curved surface, it is subjected to an external force directed to the inside of the cup body 110. Therefore, when the food fluid flows from the root where the spoiler rib 130 is connected to the inner wall of the cup body 110 to the top of the curved surface, the food fluid is gradually changed in direction and finally rushes to the stirring blade 240 in the middle of the cup body 110 at a better angle. The impact generated during the whole process is small, and the effect of changing the direction of the food fluid is also good. Further, in this embodiment, the two-dimensional equation of the involute is: x = R*cos(t)+R*pi*t / 180*sin(t), y = R*sin(t)-R*pi*t / 180*cos(t); wherein the range of R is [1, 10], and the range of t is [0, 500]. Through the above value range, the curvature of the involute can better adapt to the limited space of the cup body 110, guide the food fluid over a limited stroke, and finally guide the food fluid to the middle of the mixing cup 100 and collide with the mixing blade 240 again.

[0048] Please refer to Figure 4 In another embodiment, the spiral is an Archimedean spiral. In this embodiment, the principle that the spiral is an Archimedean spiral is similar to that of the previous embodiment and can also produce similar effects, which will not be repeated here. Specifically, the two-dimensional equation of the Archimedean spiral is: r=A*t, x=r*cos(t), y=r*sin(t); wherein the range of A is [0.1, 10], and the range of t is [0, 1000].

[0049] It should be emphasized here that, in combination with the above content, the solution provided by the present application, the specific form of at least one of the first spoiler surface 131 and the second spoiler surface 132 formed as a curved surface recessed into the interior of the spoiler rib 130 can also be, in the case where there are multiple spoiler ribs 130, and all of them are formed as the first spoiler surface 131, the first spoiler surface 131 of some spoiler ribs 130 is a curved surface of involute configuration, and the first spoiler surface 131 of the spoiler rib 130 of the other parts is a curved surface of Archimedes spiral configuration, or the first spoiler surfaces 131 of multiple spoiler ribs 130 are all curved surfaces of involute configuration, or are all curved surfaces of Archimedes spiral configuration. In the case where there are multiple spoiler ribs 130, and all of them are formed as the curved surface, the arrangement form is similar to the case where a curved surface is formed on the first spoiler surface 131 alone, and similar effects can be achieved, which will not be repeated here. In the case where there are multiple spoiler ribs 130, and the first spoiler surface 131 and the second spoiler surface 132 are both formed as the curved surface, the first spoiler surface 131 and the second spoiler surface 132 in the same spoiler rib 130 may be both curved surfaces with Archimedean spiral configuration or curved surfaces with involute configuration, or one of the first spoiler surface 131 and the second spoiler surface 132 may be a curved surface with Archimedean spiral configuration, and the other may be a curved surface with involute configuration, or the first spoiler surface 131 and the second spoiler surface 132 in different spoiler ribs 130 may be any of the first and second forms.

[0050] In one embodiment, when the blending cup 100 of the present application adopts the structural form of any of the above-mentioned embodiments, the diameter of the inscribed circle of the upper space of the crushing space defined by the inner side (i.e., the top) of the plurality of spoiler ribs 130 may be smaller than the diameter of the inscribed circle of the lower space. The advantage of such a setting is that during the whipping process of the ingredients, the ingredients surging upwards, due to the dual effects of gravity and the downward pressure and guidance of the cup body 110, surge to the core whipping area with the stirring blade 240 at the bottom of the blending cup 100. In this way, the ingredients in the blending cup 100 have the dual effects of being radially guided to the middle of the blending cup 100 and surging and rolling from top to bottom, so that the ingredients in the blending cup 100 present a three-dimensional rolling state, which makes the whipping more sufficient and the whipping effect better.

[0051] Please refer again Figures 1 to 2, the present invention also provides a cup holder assembly 200, which includes a cup holder housing 210, a cutter head 220 installed in the cup holder housing 210, and a stirring blade 240 installed on the cutter head 220. A guiding rib 230 is convexly formed on the inner wall surface of the cutter head 220. The guiding rib 230 at least includes a first guiding surface 231 and a second guiding surface 232 distributed on both sides of the guiding rib 230. Among them, at least one of the first guiding surface 231 and the second guiding surface 232 is formed into a curved surface that is recessed in the direction of the guiding rib 230 and / or the inner wall surface of the cutter head 220. The curved surface is used to guide the fluid to the middle of the cutter head 220 during the whipping process.

[0052] In an embodiment, the cutter head 220 is bowl-shaped. Among them, the cutter head 220 can be made of metal. The guiding rib 230 can be an integral structure with the cutter head 220, for example, obtained by integral casting. Of course, the guiding rib 230 can also be a split structure with the cutter head 220, and is fixed to the cutter head 220 by means such as clamping and welding. For the consideration of structural strength and manufacturing, the present application preferably adopts the form of an integral structure of the guiding rib 230 and the cutter head 220. During actual use, the cup holder assembly 200 is fixed to the bottom outer wall of the cup body 110 through the cup holder housing 210, and the cutter head 220 is relatively fixed to the bottom of the cup body 110. The cutter head 220 covers the bottom of the cup body 110 and cooperates with the cup body 110 to enclose a stirring cavity.

[0053] In order to improve the stirring effect, at least two guiding ribs 230 can be provided on the inner wall surface of the cutter head 220 of the present application. The at least two guiding ribs 230 are arranged at intervals in the circumferential direction of the cutter head 220. In the scheme shown in the drawings, 4 guiding ribs 230 are arranged at intervals in the circumferential direction on the inner wall surface of the cutter head 220. Each guiding rib 230 maintains a basically the same shape and is arranged in a long strip shape extending in the axial direction of the cutter head 220. It can be understood that the number of the guiding ribs 230 in the present application can be, in addition to the 4 shown in the drawings, for example, 3, 5, 6, etc. The present application does not limit this either.

[0054] Further, the first flow guiding surface 231 and the second flow guiding surface 232 are distributed on both sides of the flow guiding rib 230, that is, the first flow guiding surface 231 and the second flow guiding surface 232 are on both sides of the flow guiding rib 230 in the circumferential direction of the cutter head 220, and both the first flow guiding surface 231 and the second flow guiding surface 232 extend in the axial direction of the cutter head 220. Among them, the first flow guiding surface 231 and the second flow guiding surface 232 intersect at the middle of the flow guiding rib 230 and are smoothly transitioned, and the intersection of the first flow guiding surface 231 and the second flow guiding surface 232 forms the top of the flow guiding rib 230. At least one of the first flow guiding surface 231 and the second flow guiding surface 232 in the present application is formed into a curved surface that is recessed towards the inside of the flow guiding rib 230, and this curved surface is formed by the surface from the root connected to the inner wall surface of the cutter head 220 to the top of the flow guiding rib 230 being recessed towards the inside. At the same time, it can be understood that at least one of the first flow guiding surface 231 and the second flow guiding surface 232 being formed into a curved surface that is recessed towards the inside of the flow guiding rib 230 shows three situations. One situation is that only the first flow guiding surface 231 is formed into a curved surface. In this case, from the perspective of the attached drawing, when the stirring blade 240 rotates in the clockwise angle indicated by the arrow in the figure, when the food fluid in the cup body 110 assembly impacts the curved surface formed by the first flow guiding surface 231, due to the guiding effect of this curved surface, the food fluid can be guided to the middle of the cup body 110 assembly, and then the fluid material can be made to collide and contact with the stirring blade 240 again, so that the food fluid is fully whipped and cut, and the obtained food is finer. Specifically, in the rotation direction of the stirring blade 240, one end of the curved surface connected to the inner wall surface of the cutter head 220 to the other end away from the inner wall surface of the cutter head 220 gradually extends towards the inside of the cutter head 220. From another aspect, the connection line from one end of the curved surface connected to the inner wall surface of the cutter head 220 to the other end away from the inner wall surface of the cutter head 220 does not coincide with the radial direction of the cutter head 220, and in a preferred setting form, the included angle formed between this connection line and the tangential direction of the cutter head 220 where the flow guiding rib 230 is located is an acute angle, and the angle can be 30 degrees to 70 degrees. Thus, under the drive of the stirring blade 240, when the fluid food flows along the inner wall surface of the cutter head 220 and moves to the position of the flow guiding rib 230, it will be gradually guided towards the middle of the stirring cup 100 along the curved surface and then collide with the stirring blade 240 again. Further, the present application also makes the curved surface and the inner wall surface of the cutter head 220 smoothly transition. Thus, in the above guiding process, when the fluid food transitions from the inner wall surface of the cutter head 220 to the curved surface, due to the smooth transition setting, there will be no turbulent vortex phenomenon, and thus the fluid food can be efficiently guided to the cutter head 220. In another case, it can be that the second flow guiding surface 232 is formed into a curved surface, and the principle of this case is similar to the first case, and at this time the stirring blade 240 runs in the counterclockwise direction in the figure.In the third case, both the first flow guiding surface 231 and the second flow guiding surface 232 are formed as curved surfaces. In the third case, the cup body 110 assembly can be applied to the clockwise rotation mode, the counterclockwise rotation mode, and the clockwise and counterclockwise alternating rotation mode in a food processor, so that the applicability is wider.

[0055] In summary, in the technical solution of the present invention, in the structure of the cup base assembly 200, at least one of the first flow guiding surface 231 and the second flow guiding surface 232 on the flow guiding rib 230 on the inner wall of the cutter head 220 is formed as a curved surface that is recessed toward the inside of the flow guiding rib 230. Thus, during the operation of the food processor with the present application, the fluid rushes toward the inner wall of the cutter head 220 in the cup body 110 assembly due to the agitation of the stirring blade 240 and the centrifugal force in the food processor. Then, during the flow along the inner wall of the cutter head 220, it contacts the first flow guiding surface 231 and the second flow guiding surface 232. And because at least one of the first flow guiding surface 231 and the second flow guiding surface 232 is a curved surface that is recessed toward the inside of the flow guiding rib 230, through the guiding action of this curved surface, the fluid can be driven to rush toward the stirring blade 240 in the middle of the cutter head 220 along the curved surface, and then collide with the stirring blade 240 more fully, so that the food ingredients are further crushed and whipped, and thus the obtained food ingredients are finer.

[0056] Combined with the above content, the solution of the present application forms at least one of the first flow guiding surface 231 and the second flow guiding surface 232 in the flow guiding rib 230 as a curved surface that is recessed toward the inside of the flow guiding rib 230, so that the food ingredient fluid can be guided to the middle of the cutter head 220 during the whipping process. In order to make the effect more excellent in this process, in an embodiment, the contour line obtained by the intersection of the curved surface and the horizontal section is a section of a spiral line. We can know that the spiral line has a smoothly transitioning configuration. Thus, during the operation of the food ingredient fluid along this curved surface from the root to the top of the flow guiding rib 230, the flow direction gradually changes, and then it is guided to the middle of the cup body 110 assembly and collides with the stirring blade 240 more fully again. The movement of the food ingredient fluid is gentle throughout the process, and the impact on the cup body 110 assembly is small, which is beneficial to the stability during the operation of the overall structure.

[0057] In one embodiment, the spiral is an involute. Since the normal of each point on the involute must be tangent to the base circle, and the normal points to the inside of the blade disc 220, when the food fluid flows along the curved surface, it is subjected to an external force pointing to the inside of the blade disc 220. Therefore, when the food fluid runs from the root where the guide rib 230 is connected to the inner wall of the blade disc 220 to the top of the curved surface, the food fluid is gradually changed in direction and finally rushes to the mixing blade 240 in the middle of the blade disc 220 at a better angle. The impact generated during the whole process is small, and the effect of changing the direction of the food fluid flow is also better. Further, in this embodiment, the two-dimensional equation of the involute is: x = R*cos(t)+R*pi*t / 180*sin(t), y = R*sin(t)-R*pi*t / 180*cos(t); wherein the range of R is [1, 10], and the range of t is [0, 500]. Through the above value range, the curvature of the involute can better adapt to the limited space of the blade disc 220, guide the food fluid over a limited stroke, and finally guide the food fluid to the middle of the cup body 110 assembly and collide with the mixing blade 240 again.

[0058] In another embodiment, the spiral is an Archimedean spiral. In this embodiment, the principle that the spiral is an Archimedean spiral is similar to that of the previous embodiment and can also produce similar effects, which will not be repeated here. Specifically, the two-dimensional equation of the Archimedean spiral is: r=A*t, x=r*cos(t), y=r*sin(t); wherein the range of A is [0.1, 10], and the range of t is [0, 1000].

[0059] It should be emphasized here that, in combination with the above content, for the solution provided by the present application, the specific form in which at least one of the first flow guiding surface 231 and the second flow guiding surface 232 is formed into a curved surface that is recessed into the flow guiding rib 230 can also be that, when multiple flow guiding ribs 230 are provided, and when the first flow guiding surface 231 is formed into this curved surface in all cases, the first flow guiding surface 231 of some of the flow guiding ribs 230 can be a curved surface with an involute configuration, and the first flow guiding surface 231 of the other part of the flow guiding ribs 230 can be a curved surface with an Archimedean spiral configuration, or the first flow guiding surfaces 231 of multiple flow guiding ribs 230 are all curved surfaces with an involute configuration, or all are curved surfaces with an Archimedean spiral configuration. When multiple flow guiding ribs 230 are provided, and when the second flow guiding surface 232 is formed into this curved surface in all cases, the setting form is similar to the case where a curved surface is formed only on the first flow guiding surface 231, and a similar effect can also be achieved, which will not be elaborated here. And when multiple flow guiding ribs 230 are provided, when both the first flow guiding surface 231 and the second flow guiding surface 232 are formed into this curved surface, it can also be that both the first flow guiding surface 231 and the second flow guiding surface 232 of the same flow guiding rib 230 are curved surfaces with an Archimedean spiral configuration or an involute configuration, or one of the first flow guiding surface 231 and the second flow guiding surface 232 is a curved surface with an Archimedean spiral configuration, and the other is a curved surface with an involute configuration, or for the first flow guiding surface 231 and the second flow guiding surface 232 in different flow guiding ribs 230, the above first and second forms can be optionally selected.
