Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processor with good processing effect. Background Art

[0002] Existing food processors such as meat grinders and noodle mixers usually include a cup body with a built-in stirring blade and a detachable main unit located above the cup body. The main unit is equipped with a motor that is transmission-connected to the stirring blade. When using the food processor, the user places the ingredients in the cup body, and the stirring blade rotates at high speed driven by the motor to process the ingredients. The existing method of positioning the mixing blade is usually that the top end of the mixing blade shaft is engaged with the upper connector connected to the motor to achieve the positioning of the top end, and at the same time, a limit groove extending upward and open at the bottom end is provided at the bottom end of the blade shaft, and a limit column extending upward and inserted into the limit groove is provided on the bottom wall of the cup body to limit the bottom end of the mixing blade. In this way, the positioning of the entire mixing blade is achieved by limiting the top and bottom ends, but the limit groove opened at the bottom end of the mixing blade shaft or the bottom wall of the cup body is usually deep. At the same time, in order to leave a larger crushing space in the cup body, and considering the comprehensive cost and weight of the blade shaft, the diameter of the blade shaft itself cannot be made very wide, which results in the diameter of the limit groove in the blade shaft being relatively narrow, approximately between 5mm and 8mm, which results in the limit groove being not only deep but also shallow. During the food processing process, some food slurry will enter the limit groove, which is difficult for users to clean. Long-term inadequate cleaning will cause odor or even mold in the limit groove, and users cannot continue to use it.

[0003] In order to solve the problem of the blade shaft being difficult to clean, some researchers first thought of setting a groove on the inner bottom surface of the cup body, and setting a boss at the bottom of the blade shaft to be inserted into the groove. Later, in order to improve the stability of this installation method, some researchers changed the boss into a magnetic part such as a magnet, and set a matching part on the cup body that can magnetically cooperate with the magnetic part. The bottom of the blade shaft and the entire mixing blade are positioned by means of the magnetic force of the magnetic part and the matching part, thereby eliminating the need to set a limit groove on the blade shaft and set a limit shaft on the cup body, making it easier for users to clean the cup body and the mixing blade. However, users found in actual use that because the magnetic part is in direct contact with the inner wall of the cup body, it will produce greater friction with the inner wall of the cup body during the high-speed rotation of the magnetic part with the blade shaft. The magnetic part will produce a lot of black powder during the mutual friction between the magnetic part and the cup body. Some of the black powder will be directly mixed into the food, causing the food to be contaminated and the user to be unable to eat it, which seriously affects the consumer experience. Utility Model Content

[0004] The purpose of the utility model is to provide a food processor with good processing effect, so as to solve the problem of black powder generated by friction between the magnetic part and the cup body in the existing food processor, on the premise that the stirring blade is easy to clean and the assembly is stable through the magnetic part and the matching part.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processor with good processing effect, including a cup body with a built-in stirring knife and a detachable main unit arranged above the cup body, the main unit is provided with a motor that is transmission-connected to the stirring knife, the stirring knife includes a knife shaft, the bottom surface of the cup body is provided with a mounting groove, the mounting groove is plug-fitted with the bottom of the knife shaft, the bottom of the knife shaft is provided with a magnetic part, the cup body is provided with a mating part that magnetically cooperates with the magnetic part, and an isolation part is provided between the mounting groove and the magnetic part to isolate the two.

[0006] The present application provides a mounting groove on the bottom surface of the cup body, which is plugged into and matched with the bottom of the blade shaft. After the user installs the mixing blade in place, the mounting groove radially limits the bottom of the blade shaft, ensuring the stability of the mixing blade position and preventing radial movement of the mixing blade during rotation, which may cause unstable rotation. At the same time, a magnetic member is provided at the bottom of the blade shaft, and the cup body is provided with a matching member that magnetically cooperates with the magnetic member. This allows the blade shaft to not only be limited by the mounting groove, but also further limited by the magnetic cooperation between the magnetic member and the matching member, thereby further ensuring the stability of the mixing blade position. Compared with the existing solution of providing a limiting groove on the blade shaft and providing a limiting shaft on the cup body that cooperates with the limiting groove, this solution can effectively prevent food from remaining in the limiting groove and causing it to be inconvenient to clean, resulting in odor or even mold. It can further improve the rotation stability of the mixing blade while making it convenient for users to clean the mixing blade and the cup body to avoid food residue.

[0007] In addition, an isolation piece is provided between the mounting groove and the magnetic piece to isolate the two, so that the magnetic piece is isolated from the mounting groove, so that the magnetic piece does not contact the mounting groove when rotating with the blade shaft, thereby effectively avoiding the friction between the magnetic piece and the cup body when the blade shaft rotates at high speed, resulting in serious wear of the magnetic piece and the generation of more black powder which is mixed into the food, causing the food to be contaminated. At the same time, it avoids the situation where the magnetic piece is severely worn, resulting in a reduction in its magnetic attraction force and the deterioration of the limiting effect of the blade shaft, which helps to extend the service life of the entire mixing blade, realizes the isolation protection of the magnetic piece, and thus ensures the stable limiting of the blade shaft while ensuring the smooth processing of the food, thereby improving the user experience.

[0008] In a preferred implementation of a food processor with good processing effect, the isolation member includes a base plate and a positioning ring extending upward from the base plate and fixedly connected to the bottom of the knife shaft, and the magnetic member is installed in an installation cavity formed by the positioning ring and the base plate.

[0009] By setting the isolation part to include a base plate and a positioning ring extending upward from the base plate and fixedly connected to the bottom of the knife shaft, the magnetic part is installed in the installation cavity formed by the positioning ring and the base plate, so that the isolation part can isolate the magnetic part from the bottom wall of the installation groove through the base plate, and at the same time isolate the magnetic part from the side wall of the installation groove through the positioning ring, thereby achieving all-round isolation of the magnetic part from the installation groove, effectively avoiding the situation where friction between the magnetic part and the installation groove causes severe wear of the magnetic part.

[0010] In a preferred implementation of a food processor with good processing effect, a fixing groove for fixing the magnetic element is provided in the mounting cavity.

[0011] By providing a fixing groove for fixing the magnetic element in the installation cavity, the magnetic element is fixed in a limited position, ensuring the stability of the magnetic element in the installation cavity. This prevents the magnetic element from shifting as the blade shaft rotates, causing it to collide with the inner wall of the installation cavity and produce noise. It also prevents the blade shaft from radially deflecting due to the movement of the magnetic element, which can cause unstable rotation of the mixing blade. This helps to further improve the stability of the mixing blade's rotation. In addition, it can avoid the situation where the magnetic element moves, causing the blade shaft to be inserted into the installation groove in place, and the magnetic element and the mating part cannot achieve good adsorption, resulting in unstable positioning of the blade shaft.

[0012] In a preferred implementation of a food processor with good processing effect, the bottom end of the knife shaft is provided with a positioning rib extending downward into the installation cavity, and the magnetic attraction member is clamped between the positioning rib and the bottom plate; or,

[0013] The blade shaft is provided with a hollow cavity with a hollow interior and an open bottom end, the positioning ring is at least partially fixed to the inner wall of the hollow cavity, and the magnetic attraction member is fixed to the bottom plate; or,

[0014] The stirring blade further comprises a fastener which passes through the magnetic attraction part and is fastened to the bottom plate.

[0015] By providing the bottom end of the knife shaft with a positioning rib extending downward into the installation cavity, and clamping the magnetic part between the positioning rib and the base plate, the knife shaft can be installed and matched with the positioning ring through the positioning rib and can also achieve the limit fixation of the magnetic part by abutting the bottom end against the magnetic part, eliminating the need for a separate structural component to limit the magnetic part, realizing the functional integration of the positioning rib, helping to improve the compactness of the structure and reduce production costs.

[0016] By providing the blade shaft with a hollow cavity that is hollow inside and open at the bottom, the overall weight of the blade shaft is reduced, making it easier to rotate. At the same time, it can reduce the weight of the entire machine, making it easier for users to take the entire machine out and reduce the amount of blade shaft demolding required, thereby reducing production costs. It can also make the side wall thickness of the blade shaft uniform to ensure the stability of the stirring blade during rotation, avoiding the situation where the entire blade shaft is solid, resulting in a slow cooling rate after injection molding, which in turn causes reduced production efficiency. At the same time, the positioning ring is at least partially fixed to the inner side wall of the hollow cavity to achieve the connection and fixation of the isolation member and the blade shaft, and the magnetic member is fixed to the bottom plate, which improves the fixing effect of the magnetic member and ensures the stability of the magnetic member position.

[0017] In a preferred implementation of a food processing machine with good processing effect, the isolation member is provided with a fixing groove for installing the magnetic member, the fixing groove is provided with a mounting opening opening facing outward, and the outer end surface of the magnetic member is arranged closer to the inside than the mounting opening to form a first isolation gap between the magnetic member and the mounting groove.

[0018] By providing the isolation member with a fixing slot for mounting the magnetic member, and the fixing slot having an outward-facing mounting opening, the assembler can install the magnetic member directly into the fixing slot through the mounting opening, making assembly more convenient and quick, and helping to improve the assembly efficiency of the magnetic member. At the same time, the outer end surface of the magnetic member is positioned further inward than the mounting opening to form a first isolation gap between the magnetic member and the mounting slot. This isolation gap effectively prevents the magnetic member and the mounting slot from being severely worn due to friction between the magnetic member and the mounting slot.

[0019] In a preferred implementation of a food processor with good processing effect, the isolation member includes a base plate and a positioning ring extending upward from the base plate, the bottom of the knife shaft is connected to the upper part of the positioning ring, and the positioning ring is provided with a flange extending outward and overlapping the notch of the mounting groove to isolate the knife shaft from the cup body.

[0020] By connecting the bottom of the blade shaft with the upper part of the positioning ring, the connection and fixation of the isolation piece and the blade shaft are achieved. At the same time, the positioning ring is provided with a flange extending outward and overlapping the notch of the installation groove, so that the bottom wall of the cup body and the blade shaft are isolated by the flange, thereby avoiding direct contact between the two, so as to avoid severe friction between the blade shaft and the bottom wall of the cup body when the blade shaft rotates at high speed, resulting in serious wear and loud noise, which helps to extend the service life of both.

[0021] In a preferred implementation of a food processor with good processing effect, the distance from the flange bottom wall to the bottom plate is smaller than the groove depth of the mounting groove, so that a second isolation gap is formed between the bottom plate and the bottom wall of the mounting groove.

[0022] By setting the distance from the bottom wall of the flange to the bottom plate to be smaller than the depth of the mounting groove, when the flange overlaps the notch of the mounting groove, the flange supports and limits the entire isolation member and the knife shaft, so that a second isolation gap is formed between the bottom plate and the bottom wall of the mounting groove, thereby avoiding contact between the bottom plate and the bottom wall of the mounting groove, and thus avoiding friction and wear between the two. At the same time, it can also achieve isolation between the magnetic attraction member and the bottom wall of the mounting groove, effectively avoiding friction between the magnetic attraction member and the mounting groove, resulting in severe wear of the magnetic attraction member.

[0023] In a preferred implementation of a food processor with good processing effect, the blade shaft is provided with a hollow cavity with a hollow interior and an open bottom end, the magnetic attraction member is fixed in the hollow cavity, and the isolation member cover is provided at the opening of the hollow cavity; or,

[0024] The maximum outer diameter of the isolator inserted into the mounting groove is greater than or equal to the maximum outer diameter of the cutter shaft; or

[0025] The magnetic attraction part is a magnet, and the matching part is a metal part that magnetically matches the magnet.

[0026] By fixing the magnetic element in the hollow cavity, the need for providing structural components on the isolation element to achieve fixation of the magnetic element is eliminated, the structure is further simplified, which helps to improve the compactness of the stirring blade structure while reducing production costs.

[0027] In a preferred implementation of a food processor with good processing effect, the outer bottom surface of the cup body is provided with an annular accommodating groove extending vertically for installing a matching piece, and the matching piece includes a transversely extending horizontal plate and a plug-in ring connected to the outer periphery of the horizontal plate and inserted into the annular accommodating groove.

[0028] By configuring the mating piece to include a transversely extending transverse plate and a plug-in ring connected to the outer periphery of the transverse plate and inserted into the annular accommodating groove, the mating piece can achieve radial limitation through the cooperation of the plug-in ring and the accommodating groove, and at the same time achieve axial limitation through the cooperation of the transverse plate and the bottom wall of the cup body, which helps to improve the stability of the connection between the cup body and the mating piece, and can increase the matching area between the mating piece and the magnetic attraction piece, thereby increasing the magnetic attraction force of the two, thereby further improving the limiting effect on the stirring blade.

DETAILED DESCRIPTION

[0041] 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.

[0042] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific implementation methods disclosed below.

[0043] like Figures 1 to 9As shown, the utility model provides a food processor with good processing effect, including a cup body 3 with a built-in stirring knife 4 and a detachable main unit 1 arranged above the cup body 3, the main unit 1 is provided with a motor 2 that is transmission-connected to the stirring knife 4, the stirring knife 4 includes a knife shaft 41, and the bottom surface of the cup body 3 is provided with a mounting groove 31, the mounting groove 31 is plugged into the bottom of the knife shaft 41, a magnetic part 6 is provided at the bottom of the knife shaft 41, the cup body 3 is provided with a matching part 7 that magnetically cooperates with the magnetic part 6, and an isolation part 5 is provided between the mounting groove 31 and the magnetic part 6 to isolate the two.

[0044] The present invention provides a mounting groove 31 on the inner bottom surface of the cup body 3, which engages with the bottom of the blade shaft 41. This allows the user to install the mixing blade 4 in place, so that the mounting groove 31 radially limits the bottom of the blade shaft 41, ensuring the stability of the mixing blade 4 and preventing radial movement of the mixing blade 4 during rotation, which may cause unstable rotation. Furthermore, a magnetic member 6 is provided at the bottom of the blade shaft 41, and the cup body 3 is provided with a mating member 7 that magnetically engages with the magnetic member 6. This allows the blade shaft 41 to be not only limited by the mounting groove 31, but also further limited by the magnetic engagement of the magnetic member 6 and the mating member 7, further ensuring the stability of the mixing blade 4. Compared to the existing solution of providing a limiting groove on the blade shaft 41 and a limiting shaft on the cup body 3 to cooperate with the limiting groove, this solution effectively prevents food residue from remaining in the limiting groove, which is difficult to clean and may cause odor or even mold. This solution further improves the rotational stability of the mixing blade 4 and makes it easier for the user to clean the mixing blade 4 and the cup body 3 to avoid food residue.

[0045] In addition, an isolation part 5 is provided between the mounting groove 31 and the magnetic part 6 to isolate the two, so that the magnetic part 6 is isolated from the mounting groove 31, so that the magnetic part 6 does not contact the mounting groove 31 when rotating with the knife shaft 41, thereby effectively avoiding the friction between the magnetic part 6 and the cup body 3 when the knife shaft 41 rotates at high speed, causing the magnetic part 6 to wear seriously and produce more black powder and mix into the food, causing the food to be contaminated. At the same time, it avoids the situation where the magnetic part 6 is worn seriously, resulting in a decrease in its magnetic attraction force and the deterioration of the limiting effect of the knife shaft 41, which helps to extend the service life of the entire mixing knife 4, realizes the isolation protection of the magnetic part 6, and ensures the stable limiting of the knife shaft 41 while ensuring the smooth processing of food, thereby improving the user experience.

[0046] It should be noted that the present application does not specifically limit the structure of the spacer 5, which can be any one of the following embodiments:

[0047] Example 1: Figure 2As shown, in this embodiment, the isolation member 5 includes a base plate 51 and a positioning ring 52 extending upward from the base plate 51 and fixedly connected to the bottom of the blade shaft 41, and the magnetic member 6 is installed in the installation cavity formed by the positioning ring 52 and the base plate 51.

[0048] By setting the isolation member 5 to include a base plate 51 and a positioning ring 52 extending upward from the base plate 51 and fixedly connected to the bottom of the knife shaft 41, the magnetic member 6 is installed in the installation cavity formed by the positioning ring 52 and the base plate 51, so that the isolation member 5 can isolate the magnetic member 6 from the bottom wall of the installation groove 31 through the base plate 51, and at the same time isolate the magnetic member 6 from the side wall of the installation groove 31 through the positioning ring 52, thereby achieving all-round isolation of the magnetic member 6 from the installation groove 31, effectively avoiding the situation where the magnetic member 6 is severely worn due to friction between the magnetic member 6 and the installation groove 31.

[0049] Further, if Figure 2 As shown, a fixing groove 54 for fixing the magnetic element 6 is provided in the installation cavity.

[0050] By providing a fixing groove 54 for fixing the magnetic member 6 in the installation cavity, the magnetic member 6 is limited and fixed, ensuring the stability of the magnetic member 6 in the installation cavity, thereby preventing the magnetic member 6 from being displaced when rotating with the blade shaft 41, causing it to collide with the inner wall of the installation cavity and produce noise. At the same time, it prevents the movement of the magnetic member 6 from causing the blade shaft 41 to deflect radially, causing the stirring blade 4 to rotate unstably, which helps to further improve the stability of the stirring blade's rotation. In addition, it can avoid the situation where the magnetic member 6 moves, causing the blade shaft 41 to be plugged into the installation groove 31, and the magnetic member 6 and the mating part cannot achieve good adsorption, resulting in unstable positioning of the blade shaft 41.

[0051] It should be noted that the present application does not specifically limit the structure of the fixing groove 54 in this embodiment. As a preferred embodiment of the present application, Figure 2 As shown, the bottom plate 51 is further provided with a positioning post 53 extending upward and extending into the blade shaft 41. The positioning post 53, the bottom plate 51 and the positioning ring 52 together form an annular fixing groove 54. The magnetic member 6 is annular and fixed in the fixing groove 54. Further, as shown Figure 3 As shown, the magnetic member 6 can be a complete annular member; it can also be, as shown in FIG. Figure 4 As shown, a plurality of dividing ribs 55 are provided in the fixing groove 54 to divide the fixing groove 54 into a plurality of sections, and a magnetic attraction member 6 is provided in each section.

[0052] It should also be noted that the present application does not specifically limit the fixing method of the magnetic member 6 in this embodiment, and it can be any one of the following embodiments:

[0053] Implementation method 1: Figure 2As shown, in this embodiment, a positioning rib 411 extending downward into the installation cavity is provided at the bottom end of the blade shaft 41 , and the magnetic component 6 is clamped between the positioning rib 411 and the bottom plate 51 .

[0054] By providing a positioning rib 411 extending downward into the installation cavity at the bottom end of the knife shaft 41, and clamping the magnetic component 6 between the positioning rib 411 and the bottom plate 51, the knife shaft 41 can be installed and matched with the positioning ring 52 through the positioning rib 411 while also being able to limit and fix the magnetic component 6 through the abutment of the bottom end against the magnetic component 6, eliminating the need for providing a separate structural component to limit the magnetic component 6, realizing the functional integration of the positioning rib 411, and helping to improve the compactness of the structure and reduce production costs.

[0055] Implementation method 2: Figure 5 As shown, in this embodiment, the blade shaft 41 is provided with a hollow cavity 412 which is hollow inside and open at the bottom end, the positioning ring 52 is at least partially fixed to the inner wall of the hollow cavity 412, and the magnetic component 6 is fixed on the bottom plate 51.

[0056] By providing the blade shaft 41 with a hollow cavity 412 that is hollow inside and open at the bottom, it helps to reduce the overall weight of the blade shaft 41, making it easier to rotate. At the same time, it can reduce the weight of the entire machine, making it easier for users to take and put the entire machine, and can reduce the amount of blade shaft 41 that needs to be removed from the mold, thereby reducing production costs. It can also make the side wall thickness of the blade shaft 41 uniformly formed to ensure the stability of the stirring blade 4 during rotation, avoiding the situation where the entire blade shaft 41 is solid, resulting in a slow cooling rate after injection molding, which in turn causes reduced production efficiency. At the same time, the positioning ring 52 is at least partially fixed to the inner wall of the hollow cavity 412 to achieve the connection and fixation of the isolation member 5 and the blade shaft 41, and the magnetic member 6 is fixed to the bottom plate 51, thereby improving the fixing effect of the magnetic member 6 and ensuring the stability of the position of the magnetic member 6.

[0057] Specifically, if Figure 5 As shown, in this embodiment, the upper portion of the positioning ring 52 is fixedly connected to the hollow cavity 412, and the lower portion is inserted into the mounting groove 31. Of course, the positioning ring 52 is not limited to being fixedly connected to the inner wall of the hollow cavity 412 at least in part, as shown in FIG. Figure 8 As shown, the positioning ring 52 is completely embedded in the hollow cavity 412 , and at this time the bottom of the blade shaft 41 is inserted into the installation groove 31 .

[0058] Implementation method 3: Figure 6 、 Figure 7 As shown, in this embodiment, the stirring blade 4 also includes a fastener 9, which passes through the magnetic component 6 and is fastened to the base plate 51. Preferably, an upwardly extending stud 56 is provided on the bottom wall of the base plate 51, and the magnetic component 6 is annular and is sleeved on the outside of the stud 56. The fastener 9 is a bolt and is fastened to the stud 56.

[0059] Example 2: Figure 9 As shown, in this embodiment, the isolation member 5 is provided with a fixing groove 54 for installing the magnetic member 6, and the fixing groove 54 is provided with a mounting opening opening facing outward, and the outer end surface of the magnetic member 6 is arranged more inward than the mounting opening to form a first isolation gap between the magnetic member 6 and the mounting groove 31.

[0060] By providing the isolating member 5 with a fixing slot 54 for mounting the magnetic member 6, and by providing the fixing slot 54 with an outwardly opening mounting opening, the assembler can install the magnetic member 6 directly into the fixing slot 54 through the mounting opening, making assembly more convenient and quick, thereby improving the assembly efficiency of the magnetic member 6. At the same time, the outer end surface of the magnetic member 6 is positioned further inward than the mounting opening to form a first isolation gap between the magnetic member 6 and the mounting slot 31. This isolation gap effectively isolates the magnetic member 6 from the mounting slot 31, effectively preventing friction between the magnetic member 6 and the mounting slot 31, which could cause severe wear on the magnetic member 6.

[0061] It should be noted that the present application does not specifically limit the orientation of the mounting opening in this embodiment, and it can be any one of the following embodiments:

[0062] Embodiment 1: In this embodiment, the installation opening is arranged toward the bottom wall of the installation groove 31 , and the bottom surface of the magnetic attraction member 6 is higher than the bottom surface of the isolation member 5 or is flush with the bottom surface of the isolation member 5 .

[0063] Implementation method 2: Figure 9 As shown, in this embodiment, the mounting opening is arranged toward the side wall of the mounting groove 31, and the outer side wall of the magnetic member 6 is arranged more inwardly than the outer side wall of the isolating member 5. Specifically, the isolating member 5 includes a first shaft segment 57 inserted into the opening of the hollow cavity 412, and a second shaft segment located below the first shaft segment 57 and radially expanded. The second shaft segment and the lower end of the knife shaft 41 are plugged into the mounting groove 31. The second shaft segment includes a step portion 58 with the step surface facing upward. The step portion 58 and the bottom surface of the knife shaft 41 are enclosed to form a fixed groove 54, and the magnetic member 6 is clamped between the step surface and the bottom surface of the knife shaft 41. Of course, the fixed groove 54 in this embodiment is not limited to the above-mentioned setting. It can also be a concave annular groove formed on the side wall of the isolating member 5 to form the fixed groove 54.

[0064] Example 3: In this embodiment, the blade shaft 41 is provided with a hollow cavity 412 which is hollow inside and open at the bottom end, the magnetic component 6 is fixed in the hollow cavity 412, and the isolation component 5 is covered at the opening of the hollow cavity 412.

[0065] By fixing the magnetic part 6 in the hollow cavity 412, the need to set structural components on the isolation part 5 to achieve the fixation of the magnetic part 6 is eliminated, the structure is further simplified, which helps to improve the compactness of the stirring blade 4 structure and reduce production costs.

[0066] Specifically, in this embodiment, the isolation member 5 can be a flat plate, and the isolation member 5 is directly embedded in the hollow cavity 412; of course, it can also be covered on the outside of the blade shaft 41, which will not be repeated here.

[0067] As a preferred embodiment of the present application, Figure 2 As shown, the isolation member 5 includes a base plate 51 and a positioning ring 52 extending upward from the base plate 51. The bottom of the knife shaft 41 is connected to the upper part of the positioning ring 52. The positioning ring 52 is provided with a flange 521 extending outward and overlapping the notch of the mounting groove 31 to isolate the knife shaft 41 from the cup body 3.

[0068] By connecting the bottom of the blade shaft 41 with the upper part of the positioning ring 52, the connection and fixation between the isolation member 5 and the blade shaft 41 are achieved. At the same time, the positioning ring 52 is provided with a flange 521 extending outward and overlapping the notch of the mounting groove 31, so that the bottom wall of the cup body 3 and the blade shaft 41 are isolated by the flange 521, thereby avoiding direct contact between the two, so as to avoid severe friction between the blade shaft 41 and the bottom wall of the cup body 3 when the blade shaft 41 rotates at high speed, resulting in serious wear and noise on both, which helps to extend the service life of both.

[0069] Further, if Figure 2 As shown, the distance from the bottom wall of the flange 521 to the bottom plate 51 is less than the depth of the installation groove 31 , so that a second isolation gap 8 is formed between the bottom plate 51 and the bottom wall of the installation groove 31 .

[0070] By setting the distance from the bottom wall of the flange 521 to the bottom plate 51 to be smaller than the groove depth of the installation groove 31, when the flange 521 overlaps the groove opening of the installation groove 31, the flange 521 realizes the support and limitation of the entire isolation component 5 and the knife shaft 41, so that a second isolation gap 8 is formed between the bottom plate 51 and the bottom wall of the installation groove 31, thereby avoiding contact between the bottom plate 51 and the bottom wall of the installation groove 31, and thus avoiding friction and wear between the two. At the same time, it can also achieve isolation of the magnetic component 6 from the bottom wall of the installation groove 31, effectively avoiding friction between the magnetic component 6 and the installation groove 31, resulting in severe wear of the magnetic component 6.

[0071] It should be noted that the present application does not make any specific limitation on the setting position of the magnetic component 6 in this embodiment. It can be enclosed in the isolation component 5, or the isolation component 5 can be provided with a fixing groove 54 and the fixing groove 54 can be provided with an outward-facing installation port, and the outer end surface of the magnetic component 6 is arranged closer to the inside than the installation port.

[0072] It should be noted that the present application does not limit the maximum outer diameter of the isolating member 5 inserted into the mounting groove 31 and the maximum outer diameter of the knife shaft 41. As a preferred embodiment of the present application, the maximum outer diameter of the isolating member 5 inserted into the mounting groove 31 is greater than or equal to the maximum outer diameter of the knife shaft 41.

[0073] It should also be noted that the present application does not make any specific restrictions on the structure of the magnetic part 6 and the matching part 7. The magnetic part 6 and the matching part 7 can both be magnets to enhance the magnetic attraction between the two; the magnetic part 6 can also be a metal part and the matching part 7 can be a magnet; preferably, the magnetic part 6 is a magnet and the matching part 7 is a metal part that cooperates with the magnet, which can avoid the situation where the matching part 7 is set as a magnet and the cup body 3 is adsorbed by the metal part or the magnetic part 6 on the table when it is placed on the table.

[0074] As a preferred embodiment of the present application, Figure 2 As shown, the outer bottom surface of the cup body 3 is provided with an annular receiving groove 32 extending vertically for installing the matching piece 7. The matching piece 7 includes a transversely extending horizontal plate 71 and an inserting ring 72 connected to the outer periphery of the horizontal plate 71 and inserted into the annular receiving groove 32.

[0075] By configuring the mating piece 7 to include a transversely extending transverse plate 71 and a plug-in ring 72 connected to the outer periphery of the transverse plate 71 and inserted into the annular accommodating groove 32, the mating piece 7 can achieve radial limitation through the cooperation between the plug-in ring 72 and the accommodating groove, and at the same time achieve axial limitation through the cooperation between the transverse plate 71 and the bottom wall of the cup body 3, which helps to improve the stability of the connection between the cup body 3 and the mating piece 7, and can increase the cooperation area between the mating piece 7 and the magnetic attraction piece 6, thereby increasing the magnetic attraction force of the two, thereby further improving the limiting effect on the stirring blade 4.

[0076] Further, if Figure 2 As shown, the magnetic component 6 and the plug-in ring 72 at least partially overlap in height, so that the cross plate 71 can provide a downward magnetic force to the magnetic component 6, and at the same time the plug-in ring 72 can provide a radial magnetic force to the magnetic component 6, thereby achieving a limiting effect on the knife shaft 41 in two directions, which helps to further enhance the limiting effect on the knife shaft 41.

[0077] At the same time, the present application does not specifically limit the structure of the plug ring 72, which can be a complete ring, such as Figure 3 As shown, it can also be a plurality of discontinuous rings, which will not be described in detail here.

[0078] It should be noted that the present application does not specifically limit the shaping of the annular receiving groove 32. As a preferred embodiment of the present application, Figure 2 As shown, the bottom wall of the cup body 3 is provided with a downwardly convex mounting portion, and a mounting groove 31 is formed on the mounting portion. The outer bottom surface of the cup body 3 is provided with a rib surrounding the outside of the mounting portion, and the rib cooperates with the outer wall of the mounting portion to form an annular receiving groove 32.

[0079] It should be further explained that the fixation of the fitting 7 in the present application is not limited to the above-mentioned setting. It can also be that a receiving groove for installing the fitting 7 is provided on the outer bottom wall of the cup body 3, and the fitting 7 is flat and interference-embedded in the receiving groove, or fixed in the receiving groove by gluing.
