Description

Technical Field

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

[0002] Existing food processors usually include a main unit and a detachable cup body located above the main unit. The main unit is equipped with a motor, and the cup body is equipped with a stirring piece connected to the motor. When using the food processor, the user places the food in the cup body, and the motor drives the stirring piece to rotate at high speed to process the food. The existing method of realizing the transmission between the motor and the stirring piece is mainly to set a lower connector on the motor shaft of the motor, and at the same time set an upper connector at the bottom end of the blade shaft of the stirring piece. After the cup body is installed in place, the upper and lower connectors cooperate to connect to realize the transmission of torque. However, this transmission method requires a through hole to be opened in the bottom wall of the cup body for the upper connector to pass through, and bearings and seals to be set in the through hole to ensure the smoothness of rotation and the sealing of the cup body, resulting in a more complicated structure, and there will be a cleaning dead corner at the bottom of the cup body, which is difficult for users to clean it thoroughly.

[0003] In order to solve the above problems, some manufacturers will set the stirring element to include a stirring blade, a driven magnetic disk, a mounting bracket for fixing the driven magnetic disk, and a shell that accommodates the driven magnetic disk and the mounting bracket. The mounting bracket is provided with a blade shaft that extends out of the shell and is connected to the stirring blade. At the same time, an active magnetic disk is set on the motor shaft of the motor. After the cup body is installed in place, the active magnetic disk and the driven magnetic disk are magnetically attracted to realize torque transmission, thereby eliminating the step of opening a hole in the bottom wall of the cup body, eliminating cleaning dead corners, and allowing the cup body to be thoroughly cleaned. At the same time, in order to reduce the friction between the bottom end of the mounting bracket and the driven disk and the bottom wall of the shell, an upper bearing is usually set on the blade shaft to hoist and fix the entire mounting bracket and the driven disk in the shell, so that there is a gap between the mounting bracket and the driven disk and the bottom wall of the shell to reduce friction. However, in order to ensure high torque transmission between the active disk and the driven disk, the active disk and the driven disk need to have a large magnetic attraction force. When the attraction force is too large, the driven disk will move downward with the entire mounting bracket and the upper bearing, or even directly collide with the bottom wall of the shell, resulting in increased friction resistance of the mixing blade or even stuck and unable to rotate normally, seriously affecting the consumer experience. Utility Model Content

[0004] The purpose of the utility model is to provide a food processing machine with good positioning effect, so as to solve the problem in existing food processing machines that the suction force between the active magnetic disk and the driven magnetic disk is too large, which causes the mounting bracket and the upper bearing for fixing the driven magnetic disk to move downward or even collide with the bottom wall of the shell, resulting in increased friction resistance of the mixing blade and even stuck and unable to rotate normally.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processor with good positioning effect, including a cup body with a built-in stirring assembly and a motor arranged under the cup body and driving the stirring assembly to rotate, the stirring assembly includes a stirring blade, a driven magnetic disk assembly and a shell for accommodating the driven magnetic disk assembly, the driven magnetic disk assembly is provided with a blade shaft extending out of the shell and connected to the stirring blade, and a support member is provided between the driven magnetic disk assembly and the bottom wall of the shell to lift the driven magnetic disk assembly so that a space is formed between the driven magnetic disk assembly and the bottom wall of the shell.

[0006] The present application configures the stirring assembly to include a stirring blade and a driven magnetic disk assembly, and at the same time, an active magnetic disk is provided at the top end of the motor shaft of the motor, which is magnetically matched with the driven magnetic disk assembly. When the user places the cup body on the host, the active magnetic disk and the driven magnetic disk assembly are magnetically matched, so that when the motor drives the active magnetic disk to rotate, the active magnetic disk drives the driven magnetic disk to rotate through the magnetic attraction force with the driven magnetic disk assembly, thereby rotating the stirring blade. Compared with the existing method of requiring upper and lower connecting heads to realize torque transmission, the hole at the bottom of the cup body is eliminated, and thus the seals, bearings and other structures are eliminated, which helps to simplify the cup body structure, while reducing cleaning dead angles, making it easier for users to clean the cup body.

[0007] At the same time, a support member is provided between the driven disk assembly and the bottom wall of the shell to lift the driven disk assembly, so that an avoidance gap is formed between the driven disk assembly and the bottom wall of the shell. On the one hand, axial support of the driven disk assembly is achieved by the support member, avoiding the situation where only an upper bearing is provided outside the blade shaft to achieve axial limitation of the blade shaft, resulting in excessive magnetic attraction, causing the driven disk assembly and the upper bearing to move downward as a whole, thereby causing friction between the driven disk assembly and the shell, thereby achieving reliable positioning of the driven disk assembly, ensuring the stable existence of the avoidance gap, and thus improving the stability of the stirring blade. On the other hand, with the help of the avoidance gap, the driven disk assembly can be isolated from the bottom wall of the shell, avoiding direct contact that causes excessive friction between the two, resulting in the stirring blade rotating slowly or even unable to rotate, further improving the stability of the stirring blade.

[0008] In a preferred implementation of a food processor with good positioning effect, the support member is coaxially arranged with the knife shaft, and the driven magnetic disk assembly includes a permanent magnet, which is arranged around the support member.

[0009] By arranging the support member coaxially with the blade shaft, the upward support force exerted by the support member on the mounting bracket is coaxial with the limit of the upper bearing on the blade shaft, thereby ensuring the positional stability of the mounting bracket within the housing and avoiding the situation where the support member is offset relative to the blade shaft, resulting in the support force of the support member on the mounting bracket being not centered and causing the mounting bracket to tilt toward one side, thereby ensuring the supporting effect of the support member on the mounting bracket. At the same time, the permanent magnet is arranged around the support member, so that the radial area of ​​the permanent magnet can be made larger, thereby increasing the adsorption area of ​​the permanent magnet and the active magnetic disk, thereby further increasing the magnetic attraction between the permanent magnet and the active magnetic disk, allowing the mixing blade to output greater torque and improving transmission stability.

[0010] In a preferred implementation of the food processor with good positioning effect, the bottom wall of the shell is provided with a supporting portion extending upward and supported below the supporting member.

[0011] By providing a support portion extending upward and supported under the support member on the bottom wall of the shell, the support member is moved away from the bottom wall of the shell under the support of the support portion, so that the support member can further lift the mounting bracket upward when supporting the mounting bracket, further avoiding the contact between the mounting bracket and the driven magnetic disk and the bottom wall of the shell.

[0012] In a preferred implementation of a food processor with good positioning effect, the support member is a lower bearing, the support portion is supported on the first rotating portion of the lower bearing, and the driven disk assembly is provided with an abutting portion extending downward and abutting against the second rotating portion of the lower bearing.

[0013] By configuring the support member as a lower bearing, the structure is simple and easy to install. Furthermore, while the lower bearing enables relative rotation between the driven disk assembly and the housing, it can also withstand the axial force of the driven disk assembly, preventing the driven disk assembly from moving downward. Simultaneously, the support portion is supported by the first transmission portion of the lower bearing, and the driven disk assembly is provided with an abutment portion that extends downward and abuts against the second transmission portion of the lower bearing. This allows the support portion and the first transmission portion to remain relatively stationary, and the abutment portion and the second transmission portion to remain relatively stationary. Furthermore, the first transmission portion is isolated from the driven disk assembly, preventing friction between the first transmission portion and the driven disk assembly. Simultaneously, the second transmission portion is isolated from the bottom wall of the housing, preventing friction between the second transmission portion and the bottom wall of the housing. This further enhances the isolation function of the support member and ensures the stability of the stirring blade's rotation.

[0014] In a preferred implementation of a food processor with good positioning effect, the support portion is further provided with a positioning column extending upward into the shaft hole of the lower bearing.

[0015] By providing the support portion with a positioning column extending upward into the shaft hole of the lower bearing, the lower bearing can be radially positioned by the cooperation of the positioning column and the shaft hole, thereby ensuring the stability of the radial position of the lower bearing. At the same time, the axial positioning is achieved by pressing the lower bearing with the help of the mounting bracket to realize the overall positioning of the lower bearing, thereby preventing the lower bearing from moving, causing the lower bearing to support the driven disk assembly to be offset, thereby causing the driven disk assembly to be unevenly stressed and sway.

[0016] In a preferred implementation of a food processor with good positioning effect, the support member is a ball, and a first limiting groove for accommodating the ball is provided on the top of the support portion.

[0017] By configuring the support member as a ball bearing, the support member not only supports the driven disk assembly but also achieves point-to-surface coordination with the driven disk assembly, significantly reducing the contact area between the support member and the driven disk assembly, thereby making the rotation of the driven disk assembly more stable. Furthermore, a first retaining groove accommodating the ball bearing is provided at the top of the support portion to limit the ball bearing, preventing the ball bearing from rolling and causing its support for the driven disk assembly to be offset, thereby causing uneven force on the driven disk assembly and causing it to sway.

[0018] In a preferred implementation of a food processor with good positioning effect, the driven magnetic disk assembly is further provided with a second limiting groove adapted to the ball.

[0019] By providing the driven disk assembly with a second limiting groove adapted to the ball, the driven disk assembly can limit the ball, thereby avoiding the situation where the driven disk assembly moves on the ball and causes the supporting force of the ball on the driven disk assembly to be biased, and further ensuring the stability of the axial support of the driven disk assembly by the ball.

[0020] In a preferred implementation of a food processing machine with good positioning effect, the width H of the avoidance gap satisfies: 0.2 mm ≤ H ≤ 2 mm.

[0021] By setting the width H of the avoidance gap to satisfy: 0.2mm≤H≤2mm, the avoidance gap width is avoided to be too small, which may cause the driven disk assembly to contact and rub against the bottom wall of the shell due to assembly errors and production errors, causing the rotation of the stirring blade to be obstructed or even stuck; at the same time, the avoidance gap width is avoided to be too large, which may cause the distance between the active disk and the driven disk assembly to be large, resulting in the magnetic attraction force of the active disk and the driven disk assembly to be too small, and thus resulting in a small torque of the stirring blade.

[0022] In a preferred implementation of a food processor with good positioning effect, the shell is provided with an escape opening for the knife shaft to pass through, a shaft seal cooperating with the knife shaft is provided at the escape opening, and an upper bearing is provided on the outer side of the knife shaft.

[0023] A shaft seal that cooperates with the blade shaft at the escape port is installed to seal the escape port. This prevents slurry and other substances from entering the housing through the gap between the escape port and the blade shaft during food processing, which could increase friction resistance in components such as the upper bearing, generate odor, or even cause mold in the housing, thus ensuring cleanliness within the housing. An upper bearing is also installed on the outer side of the blade shaft to radially limit the blade shaft and ensure stable rotation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] As previously mentioned, conventional solutions for connecting the main unit and cup body of food processors utilize mechanical power transmission. This essentially transfers only torque between the upper and lower connectors, eliminating the technical issue of axial interaction. However, mechanical power transmission is subject to high vibration and noise, is prone to wear, and requires a fixed installation, making the structure complex and difficult to clean. Magnetic power transmission can address these issues, but it carries the potential risk of insufficient power between the active and passive magnetic disks. Therefore, it is necessary to increase the magnetic attraction between the active and passive disks to ensure that the mixing blades have sufficient power to achieve pulverization. However, the magnetic attraction between the active and passive disks does not simply transmit torque like a mechanical transmission. Instead, it generates a significant axial interaction force. Specifically, the magnetic attraction between the active and passive disks increases rapidly as the distance between them decreases. This forces the cup and stirring assembly, placed above the motor, to attract the active disk. The stirring assembly itself is already subject to a significant magnetic attraction, and this attraction is further transmitted within the stirring assembly, acting on the upper bearing, causing it to shift downward. During operation, the upper bearing rotates at high speed between the blade shaft and the housing, further driving it downward due to the magnetic attraction between the active and passive disks. Downward displacement of the upper bearing not only renders the stirring assembly inoperable, but also causes the driven disk to rub against the housing, disrupting the transmission function. Even if the upper bearing does not shift downward, it will still be subjected to excessive axial force, easily exceeding its design threshold, affecting its proper function and reducing its service life.

[0035] To address the aforementioned technical issues, the present application provides a support member between the driven disk assembly and the bottom wall of the housing to elevate the driven disk assembly. This support member is capable of withstanding the magnetic attraction between the driven and active disks, protecting the upper bearing by preventing it from shifting downward when subjected to axial forces. Furthermore, it ensures that the upper bearing can rotate more circumferentially while avoiding excessive axial forces. Furthermore, the support member prevents contact and friction between the driven disk assembly and the housing during downward displacement, thereby improving the operational stability and reliability of the stirring assembly.

[0036] like Figures 1 to 5As shown, the utility model provides a food processor with good positioning effect, including a cup body 1 with a built-in stirring assembly and a motor 2 arranged under the cup body 1 and driving the stirring assembly to rotate, the stirring assembly includes a stirring blade 3, a driven magnetic disk assembly 4 and a shell 8 for accommodating the driven magnetic disk assembly 4, the driven magnetic disk assembly 4 is provided with a blade shaft extending out of the shell 8 and connected to the stirring blade 3, and a support member 7 is provided between the driven magnetic disk assembly 4 and the bottom wall of the shell 8 to lift the driven magnetic disk assembly 4, so that a space is formed between the driven magnetic disk assembly 4 and the bottom wall of the shell 8.

[0037] The present application sets the stirring assembly to include a stirring blade 3 and a driven magnetic disk assembly 4, and at the same time, the top end of the motor 2 shaft of the motor 2 is also provided with an active magnetic disk 5 that magnetically cooperates with the driven magnetic disk assembly 4, so that after the user places the cup body 1 on the host, the active magnetic disk 5 and the driven magnetic disk assembly 4 are magnetically cooperated, so that when the motor 2 drives the active magnetic disk 5 to rotate, the active magnetic disk 5 drives the driven magnetic disk assembly 4 to rotate through the magnetic attraction force with the driven magnetic disk assembly 4, thereby causing the stirring blade 3 to rotate. Compared with the existing method of requiring torque transmission by setting upper and lower connecting heads, the hole at the bottom of the cup body 1 is eliminated, and thus the seals, bearings and other structures are eliminated, which helps to simplify the structure of the cup body 1, while reducing cleaning dead angles, making it convenient for users to clean the cup body 1.

[0038] At the same time, a support member 7 is provided between the driven disk assembly 4 and the bottom wall of the shell 8 to lift the driven disk assembly 4, so that an avoidance gap is formed between the driven disk assembly 4 and the bottom wall of the shell 8. On the one hand, the support member 7 is used to achieve axial support of the driven disk assembly 4, avoiding the situation where the upper bearing 6 is only provided outside the blade shaft 411 to achieve axial limitation of the blade shaft 411, resulting in excessive magnetic attraction, causing the driven disk assembly 4 and the upper bearing 6 to move downward as a whole, thereby causing friction between the driven disk assembly 4 and the shell 8, thereby achieving reliable positioning of the driven disk assembly 4, ensuring the stable existence of the avoidance gap, and thus improving the working stability of the stirring blade 3; on the other hand, with the help of the avoidance gap, the driven disk assembly 4 can be isolated from the bottom wall of the shell 8, avoiding direct contact that causes excessive friction between the two, causing the stirring blade 3 to rotate slowly or even unable to rotate, further improving the working stability of the stirring blade 3.

[0039] It should be noted that the present application does not specifically limit the positional relationship between the support member 7 and the knife shaft 411. As a preferred embodiment of the present application, Figure 2 As shown, the support member 7 is coaxially arranged with the blade shaft 411 , and the driven magnetic disk assembly 4 includes a permanent magnet 42 , which is arranged around the support member 7 .

[0040] By arranging the support member 7 to be coaxial with the blade shaft 411, the upward support force of the support member 7 on the mounting bracket 41 is made coaxial with the limit of the upper bearing 6 on the blade shaft 411, thereby ensuring the position stability of the mounting bracket 41 in the housing 8, avoiding the situation where the support member 7 is offset relative to the blade shaft 411, resulting in the support force of the support member 7 on the mounting bracket 41 not being centered and causing the mounting bracket 41 to tilt toward one side, thereby ensuring the supporting effect of the support member 7 on the mounting bracket 41. At the same time, the permanent magnet 42 is arranged around the support member 7, so that the radial area of ​​the permanent magnet 42 can be made larger, thereby increasing the adsorption area of ​​the permanent magnet 42 and the active magnetic disk 5, thereby further improving the magnetic attraction between the permanent magnet 42 and the active magnetic disk 5, so that the stirring blade 3 can output a greater torque and improve the stability of the transmission.

[0041] It should be noted that the present application does not specifically limit the forming of the space-avoiding gap, which may be any one of the following embodiments:

[0042] Example 1: Figure 2 As shown, in this embodiment, the bottom wall of the housing 8 is provided with a support portion 81 extending upward and supported below the support member 7 .

[0043] By providing a support portion 81 extending upward and supported under the support member 7 on the bottom wall of the shell 8, the support member 7 is kept away from the bottom wall of the shell 8 under the support of the support portion 81, so that the support member 7 can further lift the mounting bracket 41 upward when supporting the mounting bracket 41, further avoiding the contact between the mounting bracket 41 and the driven magnetic disk 6 and the bottom wall of the shell 8.

[0044] It should be further noted that the present application does not specifically limit the structure of the support member 7 in this embodiment, and it can be any one of the following embodiments:

[0045] Implementation method 1: Figure 2 、 Figure 3 As shown, in this embodiment, the support member 7 is a lower bearing, the support portion 81 is supported on the first transmission portion of the lower bearing, and the driven disk assembly 4 is provided with an abutment portion 412 extending downward and abutting against the second transmission portion of the lower bearing.

[0046] By setting the support member 7 as the lower bearing, the structure is simple and easy to install. At the same time, the support part 81 is supported on the first transmission part of the lower bearing, and the driven magnetic disk assembly 4 is provided with an abutment part 412 extending downward and abutting against the second transmission part of the lower bearing, so that the support part 81 and the first transmission part are relatively stationary, and the abutment part 412 and the second transmission part are relatively stationary, and the first transmission part is isolated from the driven magnetic disk assembly 4 to avoid friction between the first transmission part and the driven magnetic disk assembly 4. At the same time, the second transmission part is isolated from the bottom wall of the shell 8 to avoid friction between the second transmission part and the bottom wall of the shell 8, further enhancing the isolation effect of the support member 7 and ensuring the stability of the rotation of the driven magnetic disk assembly 4 and the stirring blade 3.

[0047] Furthermore, if Figure 3 As shown, the support portion 81 is further provided with a positioning column extending upward into the lower bearing shaft hole.

[0048] By providing the support portion 81 with a positioning column extending upward into the shaft hole of the lower bearing, the lower bearing can be radially positioned by the cooperation between the positioning column and the shaft hole, thereby ensuring the stability of the radial position of the lower bearing. At the same time, the axial positioning is achieved by pressing the driven disk assembly 4 on the lower bearing to achieve the overall limitation of the lower bearing, thereby avoiding the movement of the lower bearing, which causes the lower bearing to support the driven disk assembly 4 to be offset, thereby causing the driven disk assembly 4 to be unevenly stressed and sway.

[0049] It should be noted that the present application does not specifically limit the structure of the bearing in this embodiment, which may be as follows: Figure 2 、 Figure 3 The deep groove ball bearing shown in the figure has the first transmission part being the inner ring of the bearing and the second transmission part being the outer ring of the bearing; Figure 4 In the thrust ball bearing shown, the first transmission part is the lower ring, the second transmission part is the upper ring, and the support part 81 is provided with a rib 812 extending upward and surrounding the outside of the thrust ball bearing and a positioning column extending into the shaft hole of the thrust ball bearing, which will not be repeated here.

[0050] Implementation method 2: Figure 5 As shown, in this embodiment, the support member 7 is a ball, and a first limiting groove 813 for accommodating the ball is provided on the top of the support portion 81.

[0051] By configuring the support member 7 as a ball bearing, the support member 7 not only supports the driven disk assembly 4 but also achieves point-to-surface coordination with the driven disk assembly 4, significantly reducing the contact area between the support member 7 and the driven disk assembly 4, thereby making the rotation of the driven disk assembly 4 more stable. Furthermore, a first retaining groove 813 accommodating the ball bearing is provided at the top of the support portion 81 to limit the ball bearing, preventing the ball bearing from rolling and causing its support for the driven disk assembly 4 to be offset, thereby causing uneven force on the driven disk assembly 4 and causing it to sway.

[0052] Furthermore, if Figure 5 As shown, the driven disk assembly 4 is further provided with a second limiting groove 413 adapted to the ball.

[0053] By providing the driven disk assembly 4 with a second limiting groove 413 adapted to the ball, the driven disk assembly 4 is limited on the ball, thereby avoiding the situation where the driven disk assembly 4 moves on the ball and causes the supporting force of the ball on the driven disk assembly 4 to be biased, and further ensuring the stability of the axial support of the driven disk assembly 4 by the ball.

[0054] Embodiment 2: In this embodiment, the bottom wall of the support member 7 abuts against the bottom wall of the shell 8, and the bottom end of the driven disk assembly 4 is higher than the bottom end of the support member 7 to form a space between the driven disk assembly 4 and the bottom wall of the shell 8.

[0055] As a preferred embodiment of the present application, Figure 3 As shown, the driven magnetic disk assembly 4 includes a permanent magnet 42 and a mounting bracket for mounting the permanent magnet 42 , and the mounting bracket 41 is provided with a receiving groove 412 for receiving the support member 7 .

[0056] By providing an accommodating groove 412 for accommodating the support member, the support member 7 can be accommodated while improving the matching relationship between the support member 7 and the mounting bracket 41, so that the support member 7 can also cooperate with the mounting bracket 41 in the radial direction, thereby improving the stability of the connection between the two. At the same time, the height of the entire driven disk assembly 4 can be reduced, so that the avoidance gap can be reduced, thereby improving the adsorption effect of the permanent magnet 42 and the active disk 5, and improving the stability of the torque transmission between the two.

[0057] It should be noted that the present application does not specifically limit the width of the avoidance gap. As a preferred embodiment of the present application, Figure 2 As shown, the width H of the avoidance gap satisfies: 0.2 mm ≤ H ≤ 2 mm.

[0058] By setting the width H of the avoidance gap to satisfy: 0.2mm≤H≤2mm, the avoidance gap width is avoided from being too small, which may cause the driven disk assembly 4 to come into contact and rub against the bottom wall of the shell 8 due to assembly errors and production errors, causing the rotation of the stirring blade 3 to be obstructed or even stuck; at the same time, the avoidance gap width is avoided from being too large, which may cause the distance between the active disk 5 and the driven disk assembly 4 to be large, resulting in the magnetic attraction force between the active disk 5 and the driven disk assembly 4 to be too small, and thus resulting in a small torque of the stirring blade 3.

[0059] As a preferred embodiment of the present application, Figure 2 As shown, the housing 8 is provided with an escape opening for the knife shaft 411 to pass through, a shaft seal 9 that cooperates with the knife shaft 411 is provided at the escape opening, and an upper bearing 6 is provided on the outer side of the knife shaft 411.

[0060] By providing a shaft seal 9 at the escape opening that cooperates with the blade shaft 411, the escape opening is sealed, preventing slurry and the like from entering the housing 8 through the gap between the escape opening and the blade shaft 411 during food processing, thereby increasing the friction resistance of components such as the upper bearing 6, and generating odor or even mold in the housing 8, thereby ensuring the cleanliness of the housing 8. At the same time, an upper bearing 6 is sleeved on the outer side of the blade shaft 411 to achieve radial positioning of the blade shaft 411 and ensure the stability of the rotation of the blade shaft 411.

[0061] The technical solutions protected by this utility model are not limited to the above-described embodiments. It should be noted that the combination of the technical solutions of any one embodiment with the technical solutions of one or more other embodiments falls within the scope of protection of this utility model. Although the above description of this utility model has been provided in detail using general instructions and specific embodiments, it is obvious to those skilled in the art that modifications or improvements can be made based on this utility model. Therefore, 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.
