Description

Technical Field

[0001] The utility model relates to the field of food processing machines, in particular to a meat grinder with stable operation. Background Art

[0002] Existing food processing machines, such as meat grinders, have suction cups at the bottom of the mixing cups to prevent large slippage between the meat grinder cup and the work surface during operation, which would affect the stability of the operation. However, since many mixing cups are made of glass, a plastic cup holder needs to be provided at the bottom of the mixing cup, and then the suction cup is installed on the cup holder. The suction cup is fixed to the mixing cup by the cup holder, thereby indirectly achieving the installation and fixation of the suction cup.

[0003] Specifically, for example, the patent with application number 202221194982.9 discloses a food processor, the bottom of which is provided with a ring-shaped sealing ring, which can be understood as a cup holder, and a plurality of anti-skid parts are arranged on the ring-shaped sealing ring, which is equivalent to a suction cup, and the anti-skid parts are inserted into the bottom wall of the ring-shaped sealing ring, and are locked by screws to form a whole, and the center of the whole is passed through and locked by another screw from bottom to top through the ring-shaped sealing ring, the bottom wall of the container body and the shaft body. In this scheme, although the fixed setting of the suction cup is realized, it can avoid the slippage between the container body and the work surface during the working process and affect the working stability, but because it is difficult for the user to disassemble the ring-shaped sealing ring and the container body, when the dirt in the cleaning process of the food processor enters the gap between the ring-shaped sealing ring and the bottom of the container body, it is difficult for the user to remove the dirt here. In the long run, serious odor is likely to be generated here, affecting the user's experience.

[0004] In order to solve the problem that the aforementioned annular sealing ring and the cup body are difficult to disassemble and clean, and there is a peculiar smell. The patent with application number 202320693542.6 discloses a food processor assembly, including a mixing bowl and a base mounted on the outside of the mixing bowl. The mixing bowl is completely hidden in the base. The outer bottom surface of the base is provided with multiple suction cups to allow the cup holder to be adsorbed and positioned on the work surface. The bowl cover, the mixing bowl and the cup holder are fixed in the vertical direction by the fixing buckle at the top of the cup holder. The fixing ear of the bowl cover is limited in the vertical direction so that the bowl cover moves in the vertical direction. The limiting part at the top of the cup holder limits the fixing ear of the bowl cover in the circumferential direction to prevent the bowl cover from rotating circumferentially on the base. In this scheme, the detachable connection between the cup holder and the mixing bowl solves the problem of residual dirt between the mixing bowl and the cup holder. However, on the one hand, this solution has limitations on the shape of the bowl cover, that is, the bowl cover must have lugs extending radially outward; on the other hand, a larger cup holder is required to hide the mixing cup, and there are also requirements for the installation order of the mixing bowl, that is, the mixing bowl must be installed in the cup holder first, and then the bowl cover is placed on the mixing bowl. The lugs of the bowl cover must also be aligned with the limit portion, and then the fixing buckle is fastened, and finally the main unit is placed, which makes the user's installation operation more limited and the experience is not good.

[0012] A limiting plate is also arranged around the outer side of the limiting groove, and the limiting plate is arranged higher than the top end of the upper rib.

[0013] In one embodiment, the inner side surface of the cup seat is provided with a plurality of radially inwardly protruding side ribs, the side ribs are distributed at circumferential intervals along the inner side surface of the limiting groove, the limiting groove is formed between two adjacent side ribs, and the limiting protrusion is provided on the bottom side surface of the stirring cup.

[0014] In one embodiment, a sealing ring is provided at the top end of the side wall of the cup holder, and the sealing ring includes a first sealing plate attached to the inner side surface of the cup holder, and a second sealing plate covering the top end of the side wall of the cup holder and connected to the first sealing plate, and the cup holder is interference fit with the stirring cup through the sealing ring.

[0015] In one embodiment, the inner side surface of the first sealing plate is provided with a plurality of interference ribs at intervals; or,

[0016] The sealing ring also includes a third sealing plate connected to the second sealing plate and located on the outer side of the second sealing plate and bent downward. The third sealing plate is located on the outer side of the cup holder. The top of the outer side surface of the cup holder is provided with a convex edge protruding radially outward. The inner side of the third sealing plate is provided with a snap-fitting groove that snaps with the convex edge.

[0017] In one embodiment, a plurality of exhaust holes are provided on the inner surface of the cup seat for exhausting air when the stirring cup is separated from the cup seat.

[0018] In one embodiment, the outer bottom surface of the cup seat bulges toward the blending cup to form a boss, and the boss supports the outer bottom surface of the blending cup; or,

[0019] The outer bottom surface of the cup seat bulges toward the stirring cup to form a boss, and the limiting groove is arranged around the side of the boss.

[0020] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0021] 1. In order to prevent the mixing cup from slipping relative to the work surface during operation, the meat grinder of the utility model is also provided with an anti-slip part on the outer bottom surface of the cup base to improve the working stability of the food processing machine.

[0022] On this basis, the cup holder and the blending cup are detachably mounted on the bottom of the blending cup, so that when the user needs to use the food processor, the cup holder can be assembled on the blending cup; when the user needs to clean the cup body, the cup holder and the blending cup can be separated for cleaning, and then assembled after the cup holder and the blending cup are completely dry, which is convenient for users to clean and avoids residual stains and odors in the interlayer between the cup holder and the blending cup.

[0023] In this solution, the mixing cup and the cup holder realize circumferential rotation stop through the plug-in cooperation of the limiting part and the limiting groove, so as to avoid the change of the rotation speed of the mixing knife caused by the circumferential rotation of the mixing cup relative to the cup holder, thereby affecting the effect of the minced meat. There is no need to consider whether the cup cover is provided with lugs, and there is no limitation on the shape of the cup cover. At the same time, since the mixing cup only has a circumferential rotation stop relationship with the cup holder, the mixing cup and the cup cover can be installed together to form a whole and then installed with the cup holder; or the mixing cup can be installed with the cup holder first, and then the cup cover is placed on the mixing cup. In other words, this solution allows users to adopt a variety of installation orders of the cup cover, mixing cup, and cup holder, which provides a better experience. In addition, since the position of the circumferential limit is set at the bottom of the mixing cup, the center of gravity of the circumferential limit area is lowered, that is, the center of gravity of the whole machine is lowered, which is more conducive to improving the stability of the whole machine.

[0024] 2. As a preferred embodiment, by setting the limit groove on the inner bottom surface of the cup holder, the center of gravity of the limit groove is further lowered, and then the center of gravity of the limit rib of the mixing cup and the middle body limit area after the limit groove is installed is lowered, so as to further improve the circumferential anti-rotation effect and the stability of the whole machine. At the same time, the limit groove is formed by a plurality of upwardly protruding upper ribs distributed along the circumference at intervals, so that the upper ribs can be used as a necessary structure for forming the limit groove and simplifying the structure of the limit groove, and can also reduce the contact area between the outer bottom surface of the mixing cup and the limit groove when the mixing cup and the cup holder are installed in place, thereby reducing the friction and wear between the mixing cup and the cup holder and improving the service life.

[0025] 3. As a preferred embodiment, in order to make the limiting protrusion insert into the limiting groove from top to bottom smoother and more guideable, rounded corners are provided at the connection between the top surface of the upper rib and the two side surfaces of the upper rib along the circumferential direction, so that the top surface of the upper rib and the two side surfaces of the upper rib can smoothly transition. When the user installs the blender cup on the cup holder, there is no need to ensure that the limiting protrusion is directly opposite to the limiting groove. Even if it is offset, due to the setting of the rounded corners, the limiting protrusion can easily slide down from the top of the upper rib along the rounded corners and smoothly enter the limiting groove from the side of the upper rib, which greatly improves the user's installation experience.

[0026] 4. As a preferred embodiment, in order to ensure the stability of the mixing cup when placed in the cup holder, this solution sets a supporting rib at the bottom of the mixing cup to support the mixing cup. On this basis, by setting the limiting protrusion on the inner side of the supporting rib, and the supporting rib laterally shielding the limiting protrusion, on the one hand, when the mixing cup is placed away from the cup holder, the limiting protrusion will not be exposed to affect the aesthetics of the mixing cup; on the other hand, when the mixing cup is placed in the cup holder, because the bottom surface of the limiting protrusion will not be lower than the bottom of the supporting rib, and the limiting rib is located outside the limiting rib, the effective area supporting the mixing cup is larger, so the supporting rib can play a good role in supporting the mixing cup, and the placement is more stable.

[0027] Alternatively, in another embodiment, in order to further simplify the structure of the limiting protrusion, the supporting rib and the limiting protrusion can be combined into one, that is, the supporting rib can be partially bent radially inward to form the limiting protrusion. In this way, the supporting rib, as a single piece, not only supports the stirring cup, but also cooperates with the limiting groove to achieve circumferential rotation prevention.

[0028] 5. As a preferred embodiment, in addition to the circumferential limitation of the blending cup by the cup holder, the radial limitation of the blending cup by the cup holder is also crucial. We know that the radial movement of the blending cup will cause the blending knife to tilt, and then the blending knife will get stuck or stop. Therefore, in this solution, a limiting plate is provided on the outside of the limiting groove, an annular receiving groove is provided between the limiting plate and the limiting groove, and the supporting ribs of the blending cup are plugged into the receiving groove to achieve radial limitation of the bottom of the blending cup by the cup holder, thereby reducing the risk of the blending knife tilting due to the radial deviation of the blending cup, and even the risk of the blending knife getting stuck or stopping.

[0029] Alternatively, the height of the limiting plate is greater than the height of the upper rib, so that in the installed state, the upper rib is separated from the outer bottom surface of the mixing cup to avoid wear of both, which may affect the introduction effect by wearing the chamfered corner surface.

[0030] 6. As a preferred embodiment, in order to achieve the cooperation between the limiting protrusion and the limiting groove in advance when the blending cup is aligned with the cup holder, a plurality of radially inwardly protruding side ribs may be provided on the inner side of the cup holder, and the plurality of upper ribs are spaced along the circumferential direction, and the limiting groove is formed between two adjacent side ribs. In this way, when the user installs the blending cup, the limiting protrusion can be inserted into the limiting groove formed by the side ribs as long as the blending cup is slid into the cup holder shallowly, and the assembly time is higher. In addition, the side ribs are provided on the inner side of the cup holder, which is also convenient for the user to clean the cup holder. The rag can easily scrub up and down along the limiting groove without scraping at the bottom of the cup holder.

[0031] 7. As a preferred embodiment, in order to further improve the matching stability between the stirring cup and the cup holder, the present solution also optimizes the stability of the axial, axial and radial limiting of the stirring cup by the cup holder by providing a sealing ring at the top of the side wall of the cup holder, and the cup holder has an interference fit with the stirring cup through the sealing ring. At the same time, the cavity between the cup holder and the stirring cup can also form a closed cavity with negative pressure, thereby strengthening the adsorption of the stirring cup by the cup holder and improving stability. The first sealing plate attached to the inner side of the cup holder is used to achieve a close fit between the outer wall of the stirring cup and the inner wall of the cup holder; the second sealing plate, which is covered at the top of the side wall of the cup holder and connected to the first sealing plate, is used to hang the sealing ring on the top of the side wall of the cup holder.

[0032] 8. As a preferred embodiment, in order to avoid the difficulty in inserting the stirring cup through the sealing ring into the cup holder, a plurality of interference ribs are arranged at intervals on the inner side surface of the first sealing plate. The plurality of interference ribs arranged at intervals make the stirring cup only contact with the interference ribs when it initially contacts the sealing ring. Compared with the solution of contacting with the entire sealing ring, the contact area is greatly reduced, and it is more labor-saving to insert and remove the stirring cup.

[0033] Alternatively, in another embodiment, in order to prevent the sealing ring from falling out relative to the cup seat, a radially outwardly protruding rim is provided on the top of the outer side surface of the cup seat, and a snap-fitting groove that snaps with the rim is provided on the inner side of the third sealing plate. The snap-fitting groove and the rim are engaged with each other, so that the third sealing plate is vertically limited, thereby effectively preventing the entire sealing ring from falling off the cup seat when the stirring cup is separated from the cup seat.

[0034] 9. Due to the setting of the sealing ring, after the stirring cup and the cup holder are installed in place, a sealed cavity with negative pressure will be formed between the stirring cup and the cup holder. Therefore, if the user needs to quickly separate the stirring cup from the cup holder after use, if the exhaust structure is not provided, the user needs a lot of strength to separate the stirring cup from the cup holder. Therefore, in a preferred embodiment, a plurality of exhaust holes are provided on the inner surface of the cup holder for exhausting when the stirring cup is separated from the cup holder, so as to facilitate the user to separate the stirring cup from the cup holder.

[0035] 10. As a preferred embodiment, in order to further improve the stability of the stirring cup when the stirring cup and the cup holder are installed in place, the outer bottom surface of the cup holder is raised toward the stirring cup to form a boss, and the boss supports the outer bottom surface of the stirring cup.

[0036] Alternatively, in another embodiment, in order to enhance the strength of the limiting groove, a limiting groove is further arranged around the side of the boss. Meanwhile, the side wall of the boss can also form a vertical guide wall of the limiting groove to facilitate the sliding of the limiting convex part. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0048] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0049] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0050] like Figures 1 to 7 As shown, the present application provides a stable working meat grinder, including a stirring cup 3 and a main unit 1 arranged above the stirring cup 3, the cup cover of the stirring cup 3 is provided with a cup cover 2, a stirring blade 31 is detachably installed in the stirring cup 3, a positioning column is convexly provided on the inner bottom wall of the stirring cup 3, the bottom of the stirring blade 31 can be limitedly inserted on the positioning column, a motor 11 for driving is provided inside the main unit 1, and the top end of the stirring blade 31 passes through the cup cover 2 and is transmission-connected to the motor 11. The meat grinder of the present application also includes a cup holder 4, which is detachably sleeved on the outer side of the bottom of the stirring cup 3.

[0051] The cup holder 4 and the blending cup 3 are detachably mounted on the bottom of the blending cup 3, so that when the user needs to use the food processor, the cup holder 4 can be assembled on the blending cup 3; when the user needs to clean the cup body, the cup holder 4 and the blending cup 3 can be separated for cleaning, and then assembled after the cup holder 4 and the blending cup 3 are completely dry, which is convenient for the user to clean and avoids residual stains and odors in the interlayer between the cup holder 4 and the blending cup 3.

[0052] Specifically, in order to prevent the mixing cup 3 from slipping relative to the work surface during operation, the meat grinder of the utility model also has an anti-skid member on the outer bottom surface of the cup holder 4 to improve the working stability of the food processor. Preferably, the anti-skid member is an outer suction cup 41 with an opening facing downwards mounted on the cup holder 4. It can be understood that the anti-skid member can also be a wear-resistant silicone ring that is separately mounted on the bottom wall of the mixing cup 3, or a separate anti-skid pad, which is not specifically limited in this application.

[0053] Furthermore, the bottom of the stirring cup 3 of the present embodiment is provided with a limiting convex portion 32 plugged into the limiting groove 42, and the stirring cup 3 and the cup holder 4 are prevented from rotating in the circumferential direction by plugging and matching the limiting groove 42 and the limiting convex portion 32. The stirring cup 3 and the cup holder 4 are prevented from rotating in the circumferential direction by plugging and matching the limiting portion and the limiting groove 42, thereby avoiding the problem that the rotation speed of the stirring blade 31 changes due to the circumferential rotation of the stirring cup 3 relative to the cup holder 4, thereby affecting the effect of mincing meat, and there is no need to consider whether the cup cover 2 is provided with a lug, and there is no limitation on the shape of the cup cover 2.

[0054] At the same time, since the stirring cup 3 only has a circumferential rotation-stopping relationship with the cup holder 4, the stirring cup 3 and the cup cover 2 can be first installed together to form a whole and then installed with the cup holder 4; or the stirring cup 3 can be first installed with the cup holder 4, and then the cup cover 2 is set on the stirring cup 3. In other words, this solution allows users to use a variety of installation sequences of the cup cover 2, the stirring cup 3, and the cup holder 4, which provides a better experience. In addition, since the circumferential limit position is set at the bottom of the stirring cup 3, the center of gravity of the circumferential limit area is lowered, that is, the center of gravity of the whole machine is lowered, which is more conducive to improving the stability of the whole machine.

[0055] In a preferred embodiment, reference is made to Figure 2 , 3 The inner bottom surface of the cup holder 4 is provided with a plurality of upper ribs 421 protruding upwards, and the plurality of upper ribs 421 are spaced apart along the circumference, and the limiting groove 42 is formed between two adjacent upper ribs 421. By arranging the limiting groove 42 on the inner bottom surface of the cup holder 4, the center of gravity of the limiting groove 42 is further lowered, and the center of gravity of the middle body limiting area after the limiting ribs of the stirring cup 3 and the limiting groove 42 are installed is further lowered, and the effect of circumferential anti-rotation and the stability of the whole machine are further improved. At the same time, the limiting groove 42 is formed by a plurality of upper ribs 421 protruding upwards and spaced apart along the circumference, so that the upper ribs 421 can be used as a necessary structure for forming the limiting groove 42 and simplifying the structure of the limiting groove 42, and can also reduce the contact area between the outer bottom surface of the stirring cup 3 and the limiting groove 42 when the stirring cup 3 and the cup holder 4 are installed in place, thereby reducing the friction and wear between the stirring cup 3 and the cup holder 4 and improving the service life.

[0056] Preferably, the plurality of upper ribs 421 are spaced along the same circumference, and a plurality of the limiting grooves 42 are formed between any two adjacent upper ribs 421, and the width of any limiting groove 42 is the same. The number of upper ribs 421 can be between 2 and 20, for example, 2, 6, 8, 10, 12, 14, 16, 18, 20. When the number of upper ribs 421 is too large, the width of the limiting groove 42 between two adjacent upper ribs 421 will be too small, thereby increasing the convenience of installing the limiting protrusion 32 and the limiting groove 42 of the mixing cup 3.

[0057] The outer bottom surface of the mixing cup 3 is provided with a supporting rib 33 for supporting the mixing cup 3, and the limiting protrusion 32 is provided on the inner side of the supporting rib 33 and connected to the supporting rib 33. The limiting protrusion 32 can be inserted into the limiting groove 42 to achieve mutual circumferential rotation prevention between the mixing cup 3 and the cup holder 4.

[0058] It is understandable that the plurality of upper ribs 421 are spaced apart along the circumferential direction, and two layers of inner and outer layers can be provided, for example, the inner and outer circles of the limiting grooves 42 are staggered, and the corresponding outer bottom surface of the stirring cup 3 is also provided with limiting convex portions 32 located on two circumferences corresponding thereto. It is also understandable that the limiting grooves 42 can be provided at the bottom of the stirring cup 3, and the limiting convex portions 32 can be provided at the bottom of the cup holder 4.

[0059] More specifically, refer to Figure 3 In order to make the limiting protrusion 32 smoother and more guideable when inserted into the limiting groove 42 from top to bottom, chamfers 4211 are provided at the connection between the top surface of the upper rib 421 and the two side surfaces of the upper rib 421 along the circumferential direction, so that the top surface of the upper rib 421 and the two side surfaces of the upper rib 421 can be smoothly transitioned. The smooth transition mentioned here means that there is no sharp corner between the upper top surface and the side surface, which presents a smooth effect. Preferably, the upper rib 421 is a square column structure, including four side surfaces and an upper top surface and a lower bottom surface. The upper top surface is formed into an upwardly raised arc surface by two rounded surfaces. When the user installs the blending cup 3 on the cup holder 4, it is not necessary to ensure that the limiting protrusion 32 is directly opposite to the limiting groove 42. Even if the position is offset, due to the setting of the rounded corners 4211, the limiting protrusion 32 can easily slide down from the top of the upper rib 421 along the two side surfaces of the rounded corners 4211, and smoothly enter the limiting groove 42 from the side of the upper rib 421, which greatly improves the user's installation experience. Preferably, the upper rib 421 can be in the form of a small upper part and a platform lower part, so that the limiting groove 42 is large at the top and small at the bottom, which is easier to introduce the limiting protrusion 32.

[0060] In another preferred embodiment, reference is made to Figure 7 In order to make the mixing cup 3 aligned with the cup holder 4, the inner side of the cup holder 4 is provided with a plurality of radially inwardly protruding side ribs 422. The side ribs 422 are plate-like ribs extending in the radial direction, and the plate-like ribs are distributed at intervals along the circumference of the inner side of the limiting groove 42, and the limiting groove 42 is formed between two adjacent plate-like ribs. Specifically, the plate-like ribs make the two side surfaces along the circumference of the inner side of the limiting groove 42 flat, so that the limiting groove 42 formed is more regular, which is convenient for the introduction of the limiting ribs 32. In other words, when the user installs the mixing cup 3, as long as the cup holder 4 is slid into the cup holder 4 shallowly, the limiting ribs 32 can be inserted into the limiting groove 42 formed by the plate-like ribs, and the assembly time is higher. In addition, the plate-like ribs are arranged on the inner side of the cup holder 4, which is also conducive to the user's cleaning of the cup holder 4. The rag can easily scrub up and down along the limiting groove 42 without scratching at the bottom of the cup holder 4.

[0061] Specifically, the limiting protrusion 32 is provided on the bottom side of the blending cup 3. The bottom surface of the blending cup 3 is provided with a supporting rib 33 for the user to support the blending cup 3, and the limiting protrusion 32 is provided on the outside of the supporting rib 33 and connected to the supporting rib 33 to enhance the strength of the limiting protrusion 32. Of course, only the limiting protrusion 32 may also be provided.

[0062] It should be noted that, in the above embodiments, the number of the limiting protrusions 32 is not necessarily equal to the number of the limiting grooves 42 , as long as the number of the limiting protrusions 32 is not greater than the number of the limiting grooves 42 .

[0063] Furthermore, under the premise that the limiting protrusion 32 is provided on the outer bottom surface of the mixing cup 3, the present application further optimizes the setting of the limiting protrusion 32, and specifically provides the following two preferred implementation schemes:

[0064] Implementation 1:

[0065] refer to Figure 3 In order to ensure the stability of the mixing cup 3 when placed in the cup holder 4, the present solution sets a supporting rib 33 for supporting the mixing cup 3 at the bottom of the mixing cup 3. The limiting convex portion 32 is arranged on the inner side of the supporting rib 33, and the supporting rib 33 laterally blocks the limiting convex portion 32. By setting the limiting convex portion 32 on the inner side of the supporting rib 33, and the supporting rib 33 laterally blocks the limiting convex portion 32, on the one hand, when the mixing cup 3 is separated from the cup holder 4 and placed, the limiting convex portion 32 will not be exposed to affect the aesthetics of the mixing cup 3; on the other hand, when the mixing cup 3 is placed in the cup holder 4, since the bottom surface of the limiting convex portion 32 will not be lower than the bottom of the supporting rib 33, and the limiting rib is located outside the limiting rib 32, the effective area for supporting the mixing cup 3 is larger, so the supporting rib 33 can play a good role in supporting the mixing cup 3, and the placement is more stable.

[0066] Implementation 2:

[0067] refer to Figure 4 The outer bottom surface of the mixing cup 3 is provided with a supporting rib 33 for supporting the mixing cup 3, and the supporting rib 33 is bent radially inward to form the limiting protrusion 32. The supporting rib 33 can be partially bent radially inward to form the limiting protrusion 32, which simplifies the structure of the limiting protrusion 32 and combines the supporting rib 33 and the limiting protrusion 32 into one. In this way, the supporting rib 33, which is a single piece, not only plays the role of supporting the mixing cup 3, but also plays the role of plugging and cooperating with the limiting groove 42 to achieve circumferential rotation prevention. Preferably, there are two limiting protrusions 32, which are symmetrically arranged.

[0068] It can be understood that the supporting ribs 33 in embodiments 1 and 2 can be Figure 3 , 4The structure of a closed annular reinforcement in the middle can also be formed by enclosing multiple sections of reinforcement arranged at intervals.

[0069] In addition to the circumferential limitation of the mixing cup 3 by the cup holder 4, the radial limitation of the mixing cup 3 by the cup holder 4 is also very important. As we know, the radial movement of the mixing cup 3 will cause the mixing blade 31 to tilt, and then the mixing blade 31 will get stuck or stop.

[0070] To solve the aforementioned problems, in a preferred embodiment, reference is made to Figure 2 , 3 The limiting groove 42 is arranged on the inner bottom surface of the cup holder 4, and a limiting plate 43 is arranged on the outer side of the limiting groove 42, and an annular receiving groove 46 is arranged between the limiting plate 43 and the limiting groove 42. The outer bottom surface of the mixing cup 3 is provided with a supporting rib 33, and the supporting rib 33 is plugged into the receiving groove 46. In this solution, the radial limiting of the bottom of the mixing cup 3 by the cup holder 4 is realized by arranging a limiting plate 43 on the outer side of the limiting groove 42, and an annular receiving groove 46 is arranged between the limiting plate 43 and the limiting groove 42, and the supporting rib 33 of the mixing cup 3 is plugged into the receiving groove 46, so as to reduce the risk of the mixing knife 31 tilting due to the radial deviation of the mixing cup 3, and even the risk of the mixing knife 31 getting stuck or stopping.

[0071] Preferably, the top surface of the limiting plate 43 can also be used to support the mixing cup 3, and the height of the limiting plate 43 is greater than the height of the upper rib 421, so that in the installed state, the upper rib 421 is separated from the outer bottom surface of the mixing cup 3 to avoid wear and tear on both, which may affect the introduction effect if worn to the chamfered surface.

[0072] In a preferred embodiment, reference is made to Figure 3 , 5 6. In order to further improve the matching stability between the stirring cup 3 and the cup holder 4, the present solution further provides a sealing ring 5 at the top of the side wall of the cup holder 4, and the cup holder 4 is interference fit with the stirring cup 3 through the sealing ring 5, thereby optimizing the stability of the axial, axial and radial limiting of the stirring cup 3 by the cup holder 4. At the same time, the cavity between the cup holder 4 and the stirring cup 3 can also form a closed cavity with negative pressure, thereby strengthening the adsorption of the stirring cup 3 by the cup holder 4 and improving the stability.

[0073] Specifically, the sealing ring 5 at least includes a first sealing plate 51 attached to the inner side of the cup holder 4, and a second sealing plate 52 covering the top of the side wall of the cup holder 4 and connected to the first sealing plate 51. The cup holder 4 is interference-fitted with the stirring cup 3 through the sealing ring 5. The first sealing plate 51 attached to the inner side of the cup holder 4 is used to achieve a tight fit between the outer side wall of the stirring cup 3 and the inner side wall of the cup holder 4; the second sealing plate 52 covering the top of the side wall of the cup holder 4 and connected to the first sealing plate 51 is used to hang the sealing ring 5 on the top of the side wall of the cup holder 4.

[0074] It should be noted that the first sealing plate 51 attached to the inner side of the cup holder 4 in the present application means that the first sealing plate 51 is tightly fitted to the inner side of the cup holder 4, and there is no specific limitation as to whether there is glue bonding between the two.

[0075] Furthermore, the sealing ring 5 also includes a third sealing plate 53 connected to the second sealing plate 52 and bent downwardly on the outer side of the second sealing plate 52. The third sealing plate 53 is located on the outer side of the cup holder 4. The top of the outer side surface of the cup holder 4 is provided with a convex edge 47 protruding radially outward, and the inner side of the third sealing plate 53 is provided with a snap-fitting groove 531 that snaps with the convex edge 47. Of course, the convex edge 47 can also be provided at a lower position of the top of the outer side surface of the cup holder 4, as long as the convex edge 47 can be aligned with the snap-fitting groove 531. In this solution, the vertical position limitation of the third sealing plate 53 is achieved by the snap-fitting of the snap-fitting groove 531 with the convex edge 47, thereby effectively preventing the entire sealing ring 5 from being separated from the cup holder 4 when the mixing cup 3 is separated from the cup holder 4.

[0076] Furthermore, no matter whether the sealing ring 5 is provided with only the first sealing plate 51 and the second sealing plate 52, or the first sealing plate 51, the second sealing plate 52 and the third sealing plate 53. In this solution, the structure of the first sealing plate 51 is further optimized, specifically, referring to Figure 5 , 7 A plurality of interference ribs 54 are provided at intervals on the inner side surface of the first sealing plate 51 .

[0077] The interference ribs 54 are provided to prevent the mixing cup 3 from being twisted when being inserted into the cup holder 4 through the sealing ring 5. The interference ribs 54 are provided on the inner side of the first sealing plate 51 and are arranged at intervals. The interference ribs 54 are arranged at intervals so that the mixing cup 3 only contacts the interference ribs 54 when it contacts the sealing ring 5 at the beginning. Compared with the solution of contacting the entire circle of the sealing ring 5, the contact area is greatly reduced, and the mixing cup 3 is more labor-saving to insert and remove.

[0078] In a preferred embodiment, a sealing ring 5 is provided at the top of the side wall of the cup holder 4, and the cup holder 4 is interference fit with the stirring cup 3 through the sealing ring 5. Due to the provision of the sealing ring 5, after the stirring cup 3 and the cup holder 4 are installed in place, a sealed cavity with negative pressure will be formed between the stirring cup 3 and the cup holder 4. Therefore, if the user needs to quickly separate the stirring cup 3 from the cup holder 4 after use, if the exhaust structure is not provided, the user needs a lot of effort to separate the stirring cup 3 from the cup holder 4. Therefore, in a preferred embodiment, a plurality of exhaust holes 45 for exhausting air when the stirring cup 3 and the cup holder 4 are separated are provided on the inner surface of the cup holder 4, so as to facilitate the user to separate the stirring cup 3 and the cup holder 4.

[0079] The exhaust hole 45 can be closed in the assembled state, and opened when the blender cup 3 needs to be separated from the cup holder 4. For example, a detachable sealing plug can be provided at the exhaust hole 45. In this solution, there is no need to make a specific limitation on the position of the exhaust hole 45, as long as it is on the cup holder 4 and below the first sealing plate 51.

[0080] Of course, the exhaust hole 45 can also be always open, and the sealed cavity is formed on the inner side of the annular plate, and the exhaust hole 45 is arranged on the outer side of the annular plate.

[0081] For specific analysis, under a preferred solution, refer to Figure 3 A limiting plate 43 is provided on the outer side of the limiting groove 42, and a mounting area for mounting the outer suction cup 41 is provided between the outer side of the limiting plate 43 and the inner side of the cup holder 4, and a mounting hole for mounting the top of the outer suction cup 41 is provided on the mounting area, and an exhaust hole 45 for exhausting air when the stirring cup 3 is separated from the cup holder 4 is also provided on one side of the mounting hole. Through the provision of the exhaust hole 45, when the stirring cup 3 is separated from the cup holder 4 but the stirring cup 3 has not yet been completely separated from the sealing ring 5, the supporting ring rib at the bottom of the stirring cup 3 has been partially separated from the limiting plate 43, so that when the sealed cavity is opened, the gas in the cavity can be partially discharged from the exhaust hole 45 first, thereby reducing the force for the subsequent complete separation of the stirring cup 3 from the sealing rib, and accelerating the disassembly.

[0082] In a preferred embodiment, reference is made to Figure 3 , 5 In order to further improve the stability of the blending cup 3 when the blending cup 3 and the cup holder 4 are installed in place, the outer bottom surface of the cup holder 4 is raised toward the blending cup 3 to form a boss 44, and the boss 44 supports the outer bottom surface of the blending cup 3. Of course, the boss 44 can also be a boss 44 extending upwardly provided on the inner bottom surface of the cup holder 4, and the outer bottom surface of the cup holder 4 is still horizontal.

[0083] In another embodiment, in order to enhance the strength of the limiting groove 42, the limiting groove 42 is also arranged around the side of the boss 44. At the same time, the side wall of the boss 44 can also form a vertical guide wall of the limiting groove 42 to facilitate the sliding of the limiting protrusion 32.

[0084] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present utility model. Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
