Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with a stable structure. Background Technology

[0002] Existing food processing machines, such as meat grinders and dough mixers, typically include a cup body with a built-in stirring blade and a main unit located above the cup body. The main unit contains a motor that is connected to the stirring blade for transmission. When using the food processing machine, the user places the ingredients into the cup body, and the stirring blade rotates at high speed driven by the motor to process the ingredients. The stirring blade needs to be positioned while fixed in the cup body to ensure proper rotation. Existing methods for positioning the stirring blade, such as those described in Chinese patents CN200720056746.X and CN201520247250.5, involve positioning the top of the stirring blade shaft by engaging with an upper connector connected to the motor. Simultaneously, a downward-extending limiting post is provided at the bottom of the blade shaft, and a limiting groove is provided on the bottom wall of the cup body to fit into the limiting post, thus limiting the bottom of the stirring blade. In this way, the entire stirring blade is positioned by limiting the top and bottom ends. However, the limiting groove at the bottom of the blade shaft or the bottom wall of the cup is usually quite deep. In order to leave a large crushing space inside the cup, and considering the cost and weight of the blade shaft, the diameter of the blade shaft itself cannot be made very wide. This results in the limiting groove inside the blade shaft having a relatively narrow diameter of about 5mm to 8mm. Consequently, the limiting groove is not only deep but also narrow. During the food processing, some food slurry or other liquids will enter the limiting groove, which is difficult for users to clean. Long-term inadequate cleaning can lead to odors or even mold growth inside the limiting groove, making it unusable for users.

[0003] To address the difficulty of cleaning the inside of the blade shaft, some researchers initially considered creating a groove on the inner bottom surface of the cup body, with a protrusion inserted into this groove at the bottom of the blade shaft. Later, to improve the stability of this installation method, some researchers replaced the protrusion with a magnetic component such as a magnet, and added a mating part on the cup body that magnetically engages with the magnetic component. The magnetic force between the magnetic component and the mating part secures the bottom of the blade shaft and the entire mixing blade, eliminating the need for a limiting groove on the blade shaft and a limiting shaft on the cup body, thus facilitating cleaning of the cup body and the mixing blade. To facilitate the installation of the mating parts that engage with the magnets and to prevent contact between the mating parts and food, the mating parts are usually glued to the outer bottom surface of the cup body. Prolonged exposure to the outside environment and processing hot food can cause severe aging of the adhesive, leading to the mating parts detaching from the cup body. This prevents the magnetic components from engaging with the mating parts, resulting in poor or even malfunctioning cutter axis positioning. Furthermore, because the mating parts are adhered to the outer bottom surface of the cup body, the distance between the magnetic components and the mating parts is significant, greatly reducing the magnetic attraction. A solution readily apparent to those skilled in the art is to use magnets with higher magnetic strength, but this inevitably increases costs. Another approach is to thin the bottom wall of the cup body, especially the area where the mating parts are installed, as this is the area most severely stressed. However, this makes the cup body prone to breakage and deformation upon impact, severely affecting the user experience. Utility Model Content

[0004] The purpose of this invention is to provide a structurally stable food processing machine, which, at least without affecting the strength of the bottom wall of the cup, further solves the problem in existing food processing machines where the mating part that cooperates with the magnetic suction part at the bottom of the cutter shaft is installed on the outer bottom surface of the cup body, causing the mating part to easily detach from the cup body.

[0005] To achieve the above objectives, this utility model provides a food processing machine with a stable structure, including 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 connected to the stirring blade for transmission. The stirring blade includes a blade shaft. The bottom wall of the cup body is provided with a recessed mounting groove. The bottom of the blade shaft is provided with a first magnetic attraction component, and the bottom of the blade shaft is inserted into the mounting groove. The outer side of the bottom of the cup body is provided with an anti-slip component, and the anti-slip component is provided with a second magnetic attraction component that magnetically engages with the first magnetic attraction component.

[0006] This application utilizes a recessed mounting groove on the bottom wall of the cup body, with the bottom of the blade shaft engaging with the groove. This engagement of the blade shaft and the mounting groove ensures the stability of the stirring blade's position, preventing radial movement during rotation and thus avoiding instability. Compared to existing solutions that use a limiting groove on the base and a limiting shaft in the cup body that mates with the groove, this effectively prevents food residue from remaining in the limiting groove, which can lead to unpleasant odors or even mold growth. Furthermore, the outer bottom of the cup body features anti-slip components, ensuring stable contact between the cup and the work surface and improving the overall stability of the food processor. Furthermore, the bottom of the cutter shaft is equipped with a first magnetic attraction component, and the anti-slip component is equipped with a second magnetic attraction component that magnetically engages with the first magnetic attraction component. This allows the stirring blade to not only achieve positioning through the insertion and engagement with the mounting groove, but also to further achieve positioning through the magnetic engagement of the first and second magnetic attraction components. This further improves the stability of the stirring blade's position, enhances its processing stability, and prevents radial movement during the rotation of the stirring blade, which could lead to unstable rotation.

[0007] Furthermore, the anti-slip component not only prevents the cup from slipping but also enhances the positioning of the stirring blade by incorporating a second magnetic component, serving a dual purpose and simplifying the cup's structure. Compared to existing methods that place the second magnetic component on the outer bottom wall of the cup, this design eliminates the need for a fixing groove on the bottom wall, simplifying the cup's molding process, reducing production costs, and improving efficiency. With the same bottom wall thickness, the mounting groove can be made deeper, increasing the fit between the blade shaft and the mounting groove, thus further enhancing the stability of the stirring blade's positioning. On the other hand, it effectively prevents the second magnetic component from detaching from the cup due to prolonged exposure to the elements and high cup temperatures, which could lead to severe adhesion aging and prevent the first and second magnetic components from adhering and limiting the blade shaft's position. This ensures the stability of the second magnetic component's position and improves the overall stability of the fit between the first and second magnetic components.

[0008] In a preferred embodiment of a structurally stable food processing machine, the first magnetic suction component and the second magnetic suction component are coaxially arranged and centered relative to the cup body.

[0009] By setting the first and second magnetic components coaxially and centered relative to the cup body, the magnetic attraction between the first and second magnetic components ensures that the blade shaft can be positioned in the middle of the cup body, thereby achieving the centered positioning of the entire mixing blade and further improving the stability of the mixing blade position. In addition, during the food crushing process, the distance between the blade tip and the inner wall of the cup body is relatively consistent, preventing food from adhering to the side wall of the cup body on the side with a relatively large space, or from not being driven by the blade to participate in crushing.

[0010] In a preferred embodiment of a structurally stable food processing machine, the anti-slip component is provided with a support wall supported below the cup body, and the support wall is provided with a receiving groove for fixing the second magnetic component.

[0011] By providing a support wall under the cup body for the anti-slip component, and the support wall having a receiving groove for fixing the second magnetic component, the second magnetic component can be installed and fixed. At the same time, the receiving groove can not only limit the second magnetic component in the axial direction but also in the radial direction. Thus, while ensuring the axial position of the second magnetic component, its radial position can also be ensured, thereby ensuring the alignment and magnetic adsorption of the first and second magnetic components.

[0012] In a preferred embodiment of a structurally stable food processing machine, the receiving tank is located at the center of the support wall and directly below the mounting tank.

[0013] By placing the receiving groove at the center of the support wall and directly below the mounting groove, the second magnetic component is installed in a centered position relative to the cup body, ensuring that the axis of the second magnetic component is coaxial with the axis of the first magnetic component. This ensures that after the first and second magnetic components are magnetically attracted, the blade shaft can be positioned in the middle of the cup body, thereby achieving the centering and positioning of the entire stirring blade.

[0014] In a preferred embodiment of a structurally stable food processing machine, the opening of the receiving tank is covered with a cover plate that covers the second magnetic element.

[0015] By covering the opening of the receiving groove with a cover plate that covers the second magnetic component, the second magnetic component is shielded. On the one hand, the cover plate can not only fix the second magnetic component in the receiving groove, which helps to further improve the stability of the position of the second magnetic component; on the other hand, it can also hide the second magnetic component, avoiding the situation where the second magnetic component is exposed to the outside for a long time and fails to limit its position with the receiving groove, thus further improving the positional stability of the second magnetic component.

[0016] In a preferred embodiment of a structurally stable food processing machine, the second magnetic element adheres to the anti-slip element; or,

[0017] The second magnetic clamp is held between the anti-slip component and the bottom wall of the cup.

[0018] By setting the second magnetic component to adhere to the anti-slip component, the installation of the second magnetic component is simplified. The second magnetic component can be installed and fixed by simple bonding, which helps to improve the assembly efficiency of the second magnetic component. At the same time, it can save the modification of the original anti-slip component and help reduce production costs.

[0019] By setting the second magnetic component to be clamped between the anti-slip component and the bottom wall of the cup, the second magnetic component is also clamped and fixed between the anti-slip component and the bottom wall of the cup during the process of assembling the anti-slip component with the cup. This eliminates the need for additional steps to fix the second magnetic component, which helps to further improve assembly efficiency. At the same time, it also eliminates the need to modify the original anti-slip component, which helps to reduce production costs.

[0020] In a preferred embodiment of a structurally stable food processing machine, the second magnetic suction component and the anti-slip component are injection molded as a single unit.

[0021] By making the second magnetic component and the anti-slip component an integral injection molded part, the anti-slip component can also fix the second magnetic component during the production process, forming an integrated structure. This greatly ensures the stability of their cooperation, thereby improving the positional stability of the second magnetic component and ensuring the reliability of the magnetic cooperation between the first and second magnetic components. It also simplifies the assembly process and improves production efficiency.

[0022] In a preferred embodiment of a structurally stable food processing machine, the anti-slip component is bowl-shaped and fitted onto the bottom of the cup body. Multiple suction cups are provided on the outer periphery of the bottom of the anti-slip component, and a boss is provided on the inner surface of the anti-slip component. A second magnetic component is provided on the boss.

[0023] By incorporating a bowl-shaped anti-slip component that fits snugly at the bottom of the cup, the component not only prevents slipping on the cup but also protects the cup's sidewalls, enhancing its functionality. The bowl shape also improves alignment with the cup, ensuring proper centering of the first and second magnetic suction components. This magnetic attraction positions the blade shaft in the center of the cup, further stabilizing the entire mixing blade and improving its stability. Multiple suction cups on the outer circumference of the anti-slip component allow it to adhere to the work surface, further enhancing its anti-slip properties and ensuring stable contact between the cup and the work surface, ultimately improving the food processor's operational stability.

[0033] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0034] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may 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 embodiments disclosed below.

[0035] like Figures 1 to 6 As shown, this utility model provides a food processing machine with a stable structure, including a cup body 4 with a built-in stirring blade 3 and a detachable main unit 1 located above the cup body 4. The main unit 1 is equipped with a motor 2 that is connected to the stirring blade 3 for transmission. The stirring blade 3 includes a blade shaft 31. The bottom wall of the cup body 4 is provided with a recessed mounting groove 41. The bottom of the blade shaft 31 is provided with a first magnetic suction member 5, and the bottom of the blade shaft 31 is inserted into the mounting groove 41. The bottom outer side of the cup body 4 is provided with an anti-slip member 6, and the anti-slip member 6 is provided with a second magnetic suction member 7 that is magnetically attracted to the first magnetic suction member 5.

[0036] This application utilizes a recessed mounting groove 41 on the bottom wall of the cup body 4, with the bottom of the blade shaft 31 engaging with the mounting groove 41. This engagement of the blade shaft 31 and the mounting groove 41 ensures the stability of the stirring blade 3's position, preventing radial movement during rotation and thus preventing instability. Compared to existing solutions that use a limiting groove on the base and a limiting shaft on the cup body 4 that engages with the limiting groove, this effectively prevents food residue from remaining in the limiting groove, which can lead to unpleasant odors or even mold growth. Furthermore, an anti-slip element 6 is provided on the outer bottom of the cup body 4, ensuring stability between the cup body 4 and the work surface and improving the overall stability of the food processor. Furthermore, the bottom of the cutter shaft 31 is provided with a first magnetic suction element 5, and the anti-slip element 6 is provided with a second magnetic suction element 7 that magnetically engages with the first magnetic suction element 5. This allows the stirring blade 3 to not only be positioned by inserting into the mounting groove 41, but also to be further positioned by the magnetic engagement of the first magnetic suction element 5 and the second magnetic suction element 7. This further improves the stability of the stirring blade 3's position, enhances its processing stability, and prevents the stirring blade 3 from rotating radially, which could lead to unstable rotation.

[0037] Furthermore, the anti-slip component 6 not only prevents the cup body 4 from slipping, but also enhances the positioning of the stirring blade 3 by setting the second magnetic component 7, thus serving two purposes and simplifying the structure of the cup body 4. Furthermore, compared to the existing method of setting the second magnetic component 7 on the outer bottom wall of the cup body 4, on the one hand, it eliminates the need to set a fixing groove on the outer bottom wall of the cup body 4 to fix the second magnetic component 7, simplifying the molding of the cup body 4, helping to reduce the production cost of the cup body 4 and improve production efficiency. At the same time, with the same bottom wall thickness of the cup body 4, the mounting groove 41 can be set deeper, thereby increasing the mating depth between the blade shaft 31 and the mounting groove 41, and further improving the stability of the positioning of the stirring blade 3 and the mounting groove 41. On the other hand, it can effectively avoid the situation where the second magnetic component 7 is easily detached from the cup body 4 due to severe aging of the adhesion caused by prolonged exposure to the outside environment and high temperature of the cup body 4, which would prevent the first magnetic component 5 and the second magnetic component 7 from adhering to achieve the limitation of the blade shaft 31. This ensures the stability of the position of the second magnetic component 7, thereby improving the stability of the mating between the first magnetic component 5 and the second magnetic component 7.

[0038] As a preferred embodiment of this application, such as Figure 1 As shown, the first magnetic suction member 5 and the second magnetic suction member 7 are coaxially arranged and centered relative to the cup body 4.

[0039] By coaxially arranging the first magnetic suction component 5 and the second magnetic suction component 7 and centering them relative to the cup body 4, it is ensured that after the first magnetic suction component 5 and the second magnetic suction component 7 generate magnetic attraction, the blade shaft 31 can be positioned in the middle of the cup body 4, thereby achieving the centering and positioning of the entire stirring blade 3, further improving the stability of the stirring blade 3 position, and during the food crushing process, the distance between the blade tip and the inner wall of the cup body 4 is relatively consistent, so that the food on the side with relatively large space will not stick to the side wall of the cup body, or will not be driven by the blade to participate in the crushing.

[0040] It should be noted that this application does not specifically limit the fixing method of the second magnetic member 7, which can be any one of the following embodiments:

[0041] Example 1: As Figure 3 , Figure 4 As shown, in this embodiment, the anti-slip component 6 is provided with a support wall 61 supported below the cup body 4, and the support wall 61 is provided with a receiving groove 611 for fixing the second magnetic component 7.

[0042] By providing a support wall 61 under the cup body 4 for the anti-slip part 6, and the support wall 61 having a receiving groove 611 for fixing the second magnetic part 7, the second magnetic part 7 can be installed and fixed. At the same time, the receiving groove 611 can not only limit the second magnetic part 7 in the axial direction, but also limit it in the radial direction. Thus, while ensuring the axial position of the second magnetic part 7, it can also ensure its radial position, thereby ensuring the alignment and magnetic adsorption of the first magnetic part 5 and the second magnetic part 7.

[0043] It should be further noted that this application does not specifically limit the structure of the receiving groove 611 in this embodiment, and it can be any of the following embodiments:

[0044] Implementation method 1: such as Figure 4 As shown, in this embodiment, the receiving groove 611 is located at the center of the support wall 61 and directly below the mounting groove 41.

[0045] By placing the receiving groove 611 at the center of the support wall 61 and directly below the mounting groove 41, the second magnetic suction member 7 is installed in alignment with the cup body 4, ensuring that the axis of the second magnetic suction member 7 is coaxial with the axis of the first magnetic suction member 5. This ensures that after the first magnetic suction member 5 and the second magnetic suction member 7 are magnetically attracted, the blade shaft 31 can be positioned in the middle of the cup body 4, thereby achieving the centering and positioning of the entire stirring blade 3.

[0046] Implementation method 2: such as Figure 5 , Figure 6 As shown, in this embodiment, the receiving groove 611 is annular, and the central axis of the receiving groove 611 is collinear with the central axis of the mounting groove 41.

[0047] As a preferred embodiment, such as Figure 4 , Figure 6 As shown, the slot opening of the receiving groove 611 is covered with a cover plate 8 that covers the second magnetic suction member 7.

[0048] By covering the opening of the receiving groove 611 with a cover plate 8 that covers the second magnetic component 7, the second magnetic component 7 is shielded. On the one hand, the cover plate 8 can not only fix the second magnetic component 7 in the receiving groove 611, which helps to further improve the positional stability of the second magnetic component 7; on the other hand, it can also hide the second magnetic component 7, avoiding the situation where the second magnetic component 7 is exposed to the outside for a long time and fails to limit its position with the receiving groove 611, thus further improving the positional stability of the second magnetic component 7.

[0049] Example 2: In this example, the second magnetic element 7 is adhered to the anti-slip element 6.

[0050] By setting the second magnetic component 7 to adhere to the anti-slip component 6, the installation of the second magnetic component 7 is simplified. The second magnetic component 7 can be installed and fixed by simple bonding, which helps to improve the assembly efficiency of the second magnetic component 7. At the same time, it can save the modification of the original anti-slip component 6 and help to reduce production costs.

[0051] Example 3: In this example, the second magnetic member 7 is clamped between the anti-slip member 6 and the bottom wall of the cup body 4.

[0052] By setting the second magnetic component 7 to be clamped between the anti-slip component 6 and the bottom wall of the cup body 4, the second magnetic component 7 is also clamped and fixed between the anti-slip component 6 and the bottom wall of the cup body 4 during the process of assembling the anti-slip component 6 and the cup body 4 together. This eliminates the need for additional steps to fix the second magnetic component 7, which helps to further improve assembly efficiency. At the same time, it also eliminates the need to modify the original anti-slip component 6, which helps to reduce production costs.

[0053] Example 4: In this example, the second magnetic suction component 7 and the anti-slip component 6 are injection molded as a single unit.

[0054] By setting the second magnetic suction component 7 and the anti-slip component 6 as an integral injection molding, the anti-slip component 6 can also fix the second magnetic suction component 7 during the production process, making the anti-slip component 6 and the second magnetic suction component 7 form an integral structure. This greatly ensures the stability of their cooperation, thereby improving the positional stability of the second magnetic suction component 7 and ensuring the reliability of the magnetic attraction between the first magnetic suction component 5 and the second magnetic suction component 7. At the same time, it can also simplify the assembly steps and improve production efficiency.

[0055] It should be noted that this application does not specifically limit the structure of the anti-slip component 6. As one preferred embodiment of this application, such as... Figure 2 , Figure 3As shown, the anti-slip part 6 is bowl-shaped and is fitted onto the bottom of the cup body 4. Multiple suction cups are provided on the outer periphery of the bottom of the anti-slip part 6, and a boss is provided on the inner surface of the anti-slip part 6. The second magnetic suction part 7 is provided on the boss.

[0056] By shaped like a bowl and fitted onto the bottom of the cup body 4, the anti-slip component 6 not only prevents the cup body 4 from slipping but also protects the side walls of the cup body 4 through its sidewalls, thus enhancing its functionality. The bowl shape also improves the centering effect with the cup body 4, ensuring the centering of the first magnetic component 5 and the second magnetic component 7. This ensures that the blade shaft 31 is positioned in the center of the cup body 4 after the magnetic attraction between the first and second magnetic components 5 and 7, thereby achieving centering and positioning of the entire stirring blade 3 and further improving the stability of the stirring blade 3's position. Furthermore, multiple suction cups are provided on the outer periphery of the bottom of the anti-slip component 6, allowing it to adhere to the work surface, further enhancing its anti-slip effect and ensuring the stability of the contact between the cup body 4 and the work surface, thereby improving the operational stability of the food processor.

[0057] It should be noted that this application does not specifically limit the height and diameter of the mounting groove 41. As a preferred embodiment of this application, such as... Figure 1 As shown, the height H of the mounting groove 41 satisfies: 3.5mm≤H≤15mm. More preferably, H is selected as 6mm, 8mm, 10mm, etc., to avoid the situation where the insertion fit between the cutter shaft 31 and the mounting groove 41 is too shallow due to the height of the mounting groove 41 being less than 3.5mm, resulting in unstable positioning of the cutter shaft 31 by the mounting groove 41. At the same time, it avoids the situation where the height of the mounting groove 41 is too high, resulting in the bottom wall of the cup body 4 at the mounting groove 41 being too thin, resulting in low strength of the cup body 4 and easy damage from impact.

[0058] As a preferred option in this application, such as Figure 1 As shown, the diameter D of the mounting groove 41 satisfies: 8.5mm≤D≤30mm. More preferably, D is selected as 12mm, 15mm, 20mm, etc., to avoid the situation where the diameter of the mounting groove 41 is too small, resulting in a small mating area between the cutter shaft 31 and the mounting groove 41, causing poor stability of the cutter shaft 31. At the same time, it avoids the situation where the diameter of the mounting groove 41 is too large, resulting in a large contact area between the cutter shaft 31 and the mounting groove 41, causing excessive friction between the two.

[0059] The technical solutions protected by this utility model are not limited to the above embodiments. It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
