Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a food processing machine. Background Technology

[0002] Existing food processors can be divided into two types based on the motor installation position: top-mounted and bottom-mounted. For bottom-mounted food processors, in existing technology, one type, such as the one disclosed in CN201320328097.X, has a pulverizing hood inside the cup. The pulverizing hood is equipped with magnets or ferromagnetic components, and a corresponding ferromagnetic component or magnet is located at the bottom of the cup to attract and fix the pulverizing hood to the bottom of the cup. This magnetic attraction allows for detachable connection of the pulverizing hood, facilitating cleaning. However, this structure has two drawbacks. First, the detachable connection of the pulverizing hood relies on a magnetic structure, which increases the overall cost of the machine and makes the pulverizing hood installation complex, cumbersome, and inefficient. Second, even if the pulverizing hood is removed, the pulverizing blades are fixed inside the cup and cannot be disassembled, creating blind spots for cleaning the blades and the cup, resulting in poor cleaning of both.

[0003] Another type of food processor, such as the food processor disclosed in CN202323659428.0, has a motor connected to a pulverizing blade located inside the cup via a rotating shaft. The pulverizing blade is detachably connected to the rotating shaft, allowing for disassembly and cleaning of the pulverizing blade. However, processing food solely through the pulverizing blade results in relatively poor uniformity of the pulverized food and unsatisfactory pulverization effect. Furthermore, there is a risk of hand injury when disassembling the pulverizing blade. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a food processing machine that solves the problems of existing food processing machines with crushing hoods, which have complex installation structures and low assembly efficiency, while food processing without crushing hoods, which rely solely on crushing blades, results in relatively poor uniformity of food crushing and unsatisfactory crushing effects.

[0005] This application provides a food processing machine, including a cup body, a crushing device located inside the cup body, a motor, and a rotating shaft driven by the motor. One end of the rotating shaft passes through the bottom of the cup body and is connected to the crushing device. The crushing device includes a crushing hood, a connecting sleeve, and a crushing blade connected together. The crushing hood has an opening at its lower end, and the crushing blade is disposed inside the crushing hood. The crushing blade and the crushing hood are mounted on the connecting sleeve. The connecting sleeve has a mounting cavity with an opening at its lower end. The rotating shaft extends into the mounting cavity and cooperates with the connecting sleeve so that the crushing device is mounted on the rotating shaft.

[0006] Compared with existing technologies, the pulverizing device of this application includes a pulverizing hood, a connecting sleeve, and pulverizing blades connected together, all three mounted on a rotating shaft. This eliminates the need for a magnetic suction structure or a structure to fix the pulverizing hood at the bottom of the cup. The pulverizing device of this application has a simpler structure, is easier to install, and has higher assembly efficiency. Furthermore, when the food processor is running, the pulverizing blades rotate while the pulverizing hood also rotates. The rotation of the pulverizing hood alters the movement of the liquid flow, disrupting its original trend and improving the pulverizing effect. Since both the pulverizing blades and the pulverizing hood rotate, they together push the processed food ingredients to form a more regular vortex, reducing dead zones and making the food ingredients more evenly distributed within the cup, resulting in more uniform and thorough pulverization and improved food pulverization uniformity.

[0007] On the other hand, the rotation of the grinding hood can continuously break up the sediment at the bottom of the cup. Combined with the grinding blade, it can prevent the food from settling and burning during the heating process, and also reduce the graininess of the processed food, making the finished food more delicate.

[0008] In addition, both the pulverizing blade and the pulverizing hood rotate, which can generate stronger vortices to promote rapid liquid circulation, more even heat distribution, and avoid local overheating that could lead to scorching or nutrient loss.

[0009] Moreover, the shredder cover is installed outside the shredder blade and connected together to form a whole. Compared with existing technology, when cleaning the food processing machine, the shredder cover can protect the user from being injured by the shredder blade.

[0010] As a preferred technical solution, the connecting sleeve is formed by extending downward from the lower surface of the crushing cover, so that the crushing cover and the crushing blade are driven to rotate synchronously by the rotating shaft.

[0011] As one solution of this application, the connecting sleeve extends downward from the lower surface of the crushing cover and is integrally formed. On the one hand, the crushing cover and the connecting sleeve are integrally formed, which has a simple structure, simpler processing technology, and lower cost. On the other hand, it realizes the synchronous rotation of the crushing cover and the crushing blade, so that the food forms a more regular vortex, the food is more evenly distributed in the cup, and the crushing blade crushes the food more evenly and thoroughly.

[0012] As a preferred technical solution, the connecting sleeve includes a first connecting sleeve and a second connecting sleeve connected to the upper end of the first connecting sleeve, and the crushing cover is installed between the first connecting sleeve and the second connecting sleeve.

[0013] The connecting sleeve includes a first connecting sleeve and a second connecting sleeve, and the crushing cover is clamped and fixed between the two, which can also realize the synchronous rotation of the crushing cover and the crushing blade to improve the uniformity of food crushing.

[0014] As a preferred technical solution, the crushing hood is fixedly clamped between the first connecting sleeve and the second connecting sleeve;

[0015] The crushing hood is clamped and fixed between the two, which enables the crushing hood and the crushing blade to rotate synchronously, thereby improving the uniformity of food crushing.

[0016] Alternatively, the crushing shroud may be rotatably positioned between the first connecting sleeve and the second connecting sleeve.

[0017] Compared to the synchronous rotation of the crushing hood and the crushing blade, the crushing hood is rotatably positioned between the first and second connecting sleeves. The crushing hood can be driven to rotate by the eddy current generated during food processing, thereby achieving relative rotation with the crushing blade. On the one hand, the motor only drives the crushing blade to rotate, and will not cause excessive load due to driving the crushing hood to rotate (the crushing hood speed is too high); on the other hand, the rotation of the crushing hood, in conjunction with the rotation of the crushing blade, can generate stronger eddy currents, resulting in more uniform crushing of the food and improving the processing effect.

[0018] As a preferred technical solution, the connecting sleeve includes a first connecting sleeve installed inside the crushing hood and a locking sleeve connected to the first connecting sleeve, and the locking sleeve clamps and fixes the crushing blade between the first connecting sleeve and the first connecting sleeve.

[0019] As a preferred technical solution, the first connecting sleeve includes a first connecting segment and a second connecting segment connected together, with a stepped surface formed between the first connecting segment and the second connecting segment. The locking sleeve is threadedly connected to the second connecting segment to clamp and fix the crushing blade between the end face of the locking sleeve and the stepped surface.

[0020] As a preferred technical solution, the side wall of the connecting sleeve is provided with a sliding groove, which extends upward in the circumferential direction from the bottom of the connecting sleeve. One end of the rotating shaft extends into the connecting sleeve and one end of the rotating shaft is provided with a protrusion. The protrusion cooperates with the sliding groove so that the crushing device can be detachably installed on the rotating shaft.

[0021] By setting up a chute and a protrusion, with the protrusion cooperating with the chute, the crushing device can be detachably installed on the rotating shaft. On the other hand, during the operation of the food processing machine, the protrusion on the rotating shaft abuts against the inner wall of the chute, which can prevent the inner sleeve from detaching from the rotating shaft, thus preventing the crushing device from detaching from the rotating shaft and improving the safety of use.

[0022] Furthermore, the installation of the rotating shaft and the connecting sleeve is achieved by limiting the protrusion in the sliding groove. The crushing cover, connecting sleeve and crushing blade of this application are connected together, so that the crushing device can be detachably connected to the rotating shaft as a whole, which facilitates the disassembly of the crushing device and allows the crushing device and the cup body to be thoroughly cleaned, effectively improving the cleaning effect and avoiding cleaning dead corners of the cup body or crushing blade.

[0023] As a preferred technical solution, the connecting sleeve includes an inner sleeve and a first connecting sleeve fixedly sleeved outside the inner sleeve. The first connecting sleeve is located inside the crushing hood, and the sliding groove is provided on the side wall of the inner sleeve.

[0024] As a preferred technical solution, the slide groove is spiral-shaped, and the lower end of the slide groove is flared, and the protrusion is slidably placed in the slide groove through the flared opening.

[0025] The flared opening facilitates the installation between the shaft and the inner sleeve, and the spiral groove can abut against the protrusion, thus preventing the inner sleeve from detaching from the shaft.

[0026] As a preferred technical solution, two slides are provided, and the two slides are symmetrically and through the side wall of the connecting sleeve;

[0027] The protrusion is provided in two parts, and each of the two protrusions is limited to one of the grooves.

[0028] As a preferred technical solution, the crushing device includes a gripper, which is located on top of the crushing hood and fixed to the connecting sleeve; or the gripper is fixed to the top of the crushing hood. Attached Figure Description

[0041] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0043] Example 1

[0044] Considering existing food processors, especially those with a bottom-mounted motor, those with a pulverizing cover, such as the one disclosed in CN201320328097.X, where the pulverizing cover is fixed to the bottom of the cup via a magnetic structure, suffer from complex installation structures and cumbersome installation processes. Another example is the food processor disclosed in CN202323659428.0, which features a detachable pulverizing blade but lacks a pulverizing cover, processing ingredients solely through the blade, resulting in uneven pulverization and poor pulverization performance. This application provides a food processor with a simpler pulverizing cover installation structure and a more streamlined installation process. Furthermore, it improves the uniformity of ingredient pulverization while ensuring effective cleaning of the blade and cup, eliminating cleaning dead zones, and producing finer processed ingredients.

[0045] For example, such as Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the assembly structure of the crushing device, rotating shaft 1, and heating element 2 of the food processing machine described in Embodiment 1 of this application;

[0046] Figure 2 This is a cross-sectional view of the pulverizing device and rotating shaft 1 of the food processor according to Embodiment 1 of this application. The food processor of this application includes a cup body, a pulverizing device, a motor, and a rotating shaft 1. A heating element 2 is provided at the bottom of the cup body. The pulverizing device is installed inside the cup body. The rotating shaft 1 is driven to rotate by the motor, and one end of the rotating shaft 1 passes through the bottom of the cup body and connects to the pulverizing device to drive the pulverizing device to rotate and pulverize the food. Preferably, the rotating shaft 1 is detachably connected to the pulverizing device, thus enabling the pulverizing device to be detached independently. This facilitates separate cleaning of the cup body and the pulverizing device, eliminating blind spots in cleaning the inside of the cup body and the pulverizing device.

[0047] In this embodiment, the aforementioned pulverizing device includes a pulverizing cover 3, a connecting sleeve, and a pulverizing blade 5 connected together. The connecting sleeve has a hollow structure, and one end of the rotating shaft 1 extends into the connecting sleeve, enabling the connecting sleeve to rotate. The pulverizing blade 5 is fixed outside the connecting sleeve and rotates synchronously with it. In other words, in this embodiment, the rotating shaft 1 drives the pulverizing blade 5 to rotate through the connecting sleeve. This application uses the pulverizing cover 3, the connecting sleeve, and the pulverizing blade 5, all mounted together on the rotating shaft 1, eliminating the need for a magnetic suction structure or a structure to fix the pulverizing cover at the bottom of the cup. The pulverizing device in this embodiment has a simpler structure, is more convenient to install, and has higher assembly efficiency. Furthermore, when the food processor is running, the grinding blade 5 rotates while the grinding hood 3 is also rotating. The rotation of the grinding hood 3 will change the movement of the liquid flow, thereby disrupting the original movement trend of the liquid flow and improving the grinding effect. Moreover, since both the grinding blade 5 and the grinding hood 3 are rotating, the grinding hood 3 and the grinding blade 5 together push the processed food to form a more regular vortex, reduce the dead corners of the stirring, and make the food more evenly distributed in the cup, thus making the food more evenly and thoroughly ground and improving the uniformity of food grinding.

[0048] In addition, the crushing cover 3, the connecting sleeve and the crushing blade 5 of this application are connected together, and the rotating shaft 1 is detachably connected to the connecting sleeve, so that the crushing device can be disassembled as a whole, which facilitates the comprehensive cleaning of the crushing device and the cup body, effectively improving the cleaning effect and avoiding cleaning dead corners of the cup body or the crushing blade 5.

[0049] The aforementioned connecting sleeve is at least partially located inside the grinding chamber 3, allowing the externally fixed grinding blade 5 to be placed inside the grinding chamber 3. The grinding chamber 3 has an opening at its lower end and is rotatable. That is, when the food processor is running, while the grinding blade 5 is driven to rotate by the rotating shaft 1, the grinding chamber 3 is also rotating. With both the grinding blade 5 and the grinding chamber 3 rotating, they together push the processed food to form a more regular vortex, reducing dead zones in the mixing process and making the food more evenly distributed within the cup. Consequently, the grinding blade 5 grinds the food more evenly and thoroughly, improving the uniformity of food grinding.

[0050] On the other hand, the rotation of the grinding cover 3 can continuously break up the sediment at the bottom of the cup. Combined with the grinding blade 5, it can prevent the food from settling and burning during the heating process, and also reduce the graininess of the processed food, making the finished food more delicate.

[0051] In addition, both the pulverizing blade 5 and the pulverizing hood 3 rotate, which can generate stronger vortices to promote rapid liquid circulation, more uniform heat distribution, and avoid local overheating that could lead to scorching or nutrient loss.

[0052] It should be noted that in this embodiment, the pulverizing cover 3 is installed outside the pulverizing blade 5 and connected together to form a whole. Compared with the prior art, when cleaning the food processing machine, the pulverizing cover 3 can protect the user from being injured by the pulverizing blade 5.

[0053] In this embodiment, both the pulverizing cover 3 and the pulverizing blade 5 are driven to rotate synchronously by the rotating shaft 1. For example, as shown... Figure 2 As shown, in this embodiment, the connecting sleeve is integrally formed by extending downward from the lower surface of the crushing cover 3. In this embodiment, the connecting sleeve is defined as the first connecting sleeve 41. One end of the rotating shaft 1 is detachably inserted into the first connecting sleeve 41. The crushing blade 5 is fixedly installed outside the first connecting sleeve 41. The rotating shaft 1 is driven to rotate by the motor, and the rotating shaft 1 drives the first connecting sleeve 41 to rotate, thereby simultaneously driving the crushing cover 3 and the crushing blade 5 to rotate.

[0054] The aforementioned first connecting sleeve 41 is designed so that the crushing cover 3 and the first connecting sleeve 41 are integrally formed, which has a simple structure, a simpler processing technology, and a lower cost. On the other hand, it realizes the synchronous rotation of the crushing cover 3 and the crushing blade 5, so that the food forms a more regular vortex and the food is more evenly distributed in the cup, thereby the crushing blade 5 crushes the food more evenly and thoroughly.

[0055] In this embodiment, the lower end of the first connecting sleeve 41 is connected to the locking sleeve 42, and the locking sleeve 42 and the first connecting sleeve 41 clamp and fix the crushing blade 5. The crushing blade 5 can be clamped and fixed by the first connecting sleeve 41 and the locking sleeve 42.

[0056] Optionally, the first connecting sleeve 41 in this embodiment can have a stepped structure. For example, the first connecting sleeve 41 may include a first connecting segment and a second connecting segment arranged vertically, wherein the diameter of the second connecting segment is smaller than that of the first connecting segment, the crushing blade 5 is sleeved on the outside of the second connecting segment, and an external thread is provided on the outside of the second connecting segment. The inner wall of the locking sleeve 42 is provided with an internal thread, and the locking sleeve 42 and the second connecting segment are threadedly connected to clamp and fix the crushing blade 5. Of course, the second connecting segment and the locking sleeve 42 can also be fixed by other methods such as magnetic attraction or welding.

[0057] In this embodiment, as Figure 2 As shown, a protrusion 11 is provided at one end of the rotating shaft 1 that extends into the first connecting sleeve 41. A groove (not shown in the figure) is provided on the inner wall of the first connecting sleeve 41. The groove extends upward circumferentially from the bottom of the first connecting sleeve 41 and is spiral in shape. The protrusion 11 can slide into the groove. Through the cooperation between the protrusion 11 and the groove, the crushing device can be detachably installed on the rotating shaft 1. It also enables the rotating shaft 1 to drive the first connecting sleeve 41 to rotate, thereby driving the crushing cover 3 and the crushing blade 5 to rotate synchronously. Of course, it can be understood that the end of the rotating shaft 1 that extends into the first connecting sleeve 41 can also be fixed in the first connecting sleeve 41 by means of snap-fit ​​or other methods.

[0058] In this embodiment, the crushing device also includes a gripper 6, which can be fixed to the first connecting sleeve 41. At this time, the gripper 6 passes through the crushing cover 3 and is located at the top of the crushing cover 3. By setting the gripper 6, the crushing device can be directly lifted to detach it from the rotating shaft 1, thereby achieving quick disassembly of the crushing device. Of course, the gripper 6 can also be directly fixed to the top of the crushing cover 3.

[0059] Example 2

[0060] This embodiment provides a food processing machine, which differs from Embodiment 1 in that the structure of the connecting sleeve is different. Specifically, please refer to... Figure 3 and Figure 4 ,in Figure 3 This is an exploded structural diagram of the pulverizing device of the food processing machine described in Embodiment 2, showing its cooperation with the rotating shaft 1. Figure 4 This is a cross-sectional view of the pulverizing device of the food processor described in Embodiment 2 cooperating with the rotating shaft 1. The connecting sleeve of the food processor in this embodiment includes an inner sleeve 43 and a first connecting sleeve 41 fixedly sleeved outside the inner sleeve 43. The first connecting sleeve 41 is located inside the pulverizing cover 3. Specifically, the first connecting sleeve 41 is integrally formed on the lower surface of the pulverizing cover 3, and the pulverizing blade 5 is fixed outside the first connecting sleeve 41.

[0061] like Figure 5 As shown, Figure 5This is a schematic diagram of the inner sleeve 43 and the rotating shaft 1 of the food processing machine described in Embodiment 2. The inner sleeve 43 has a sliding groove 431 on its side wall, which extends circumferentially upwards from the bottom of the inner sleeve 43. One end of the rotating shaft 1 extends into the inner sleeve 43, and one end of the rotating shaft 1 has a protrusion 11. This protrusion 11 can slide within the sliding groove 431 and is ultimately confined within it. This allows the crushing device to be detachably installed on the rotating shaft 1, and also enables the rotating shaft 1 to drive the inner sleeve 43 to rotate, which in turn drives the first connecting sleeve 41, the crushing cover 3, and the crushing blade 5 to rotate, achieving synchronous rotation of the crushing cover 3 and the crushing blade 5. On the other hand, the protrusion 11 is located within the chute 431. During the operation of the food processing machine, the centrifugal force generated will cause the inner sleeve 43 to tend to move upward. At this time, the protrusion 11 will abut against the inner wall of the chute 431 to suppress the upward movement of the inner sleeve 43, thereby restricting the inner sleeve 43 from disengaging from the rotating shaft 1, which also restricts the crushing device from disengaging from the rotating shaft 1 and improves the safety of use.

[0062] In this embodiment, preferably, two slide grooves 431 are provided, and the two slide grooves 431 are symmetrically and through the side wall of the inner sleeve 43. Correspondingly, two protrusions 11 are also provided, and each of the two protrusions 11 is limited to one slide groove 431. Through the cooperation of the two slide grooves 431 and the two protrusions 11, the connection between the crushing device and the rotating shaft 1 is more stable.

[0063] like Figure 5 As shown, the slide groove 431 in this embodiment is spiral-shaped, and the lower end of the slide groove 431 forms a flared opening 4311. This flared opening 4311 has a tapering structure from bottom to top, meaning that the width is largest at the bottom and gradually decreases upwards. The protrusion 11 slides within the slide groove 431 through the flared opening 4311. This structure facilitates the installation between the rotating shaft 1 and the inner sleeve 43. The protrusion 11 only needs to enter the slide groove 431 through the flared opening 4311 and slide along the spiral slide groove 431 to its final position to complete the connection between the rotating shaft 1 and the inner sleeve 43. On the other hand, the spiral slide groove 431 can abut against the protrusion 11 during the operation of the food processing machine, thereby preventing the inner sleeve 43 from detaching from the rotating shaft 1. Of course, it can be understood that the slide groove 431 can also be an inclined straight line, which can also achieve abutment against the protrusion 11 during the operation of the food processing machine.

[0064] The other structures in this embodiment are the same as in Embodiment 1. For example, the method of fixing the pulverizing blade 5 is the same as in Embodiment 1. In this embodiment, the pulverizing blade 5 is fixed by clamping it with the first connecting sleeve 41 and the locking sleeve 42. The structural principle of the first connecting sleeve 41 is the same as that of the connecting sleeve described in Embodiment 1, and will not be repeated here. Similarly, the gripper 6 is also the same as in Embodiment 1. For example, the gripper 6 can be fixed to the inner sleeve 43, in which case the gripper 6 passes through the pulverizing cover 3 and is located at the top of the pulverizing cover 3. The gripper 6 can also be directly fixed to the top of the pulverizing cover 3.

[0065] Example 3

[0066] This embodiment provides a food processing machine, which differs from Embodiment 1 in the connection method of the crushing hood 3 and the structure of the connecting sleeve. Specifically, as shown... Figure 6 As shown, Figure 6 This is a cross-sectional view of the pulverizing device of the food processor described in Embodiment 3, in conjunction with the rotating shaft 1. The connecting sleeve of this food processor includes a first connecting sleeve 41 and a second connecting sleeve 44 connected to the upper end of the first connecting sleeve 41. The connection between the first connecting sleeve 41 and the second connecting sleeve 44 can be a threaded connection, such as the upper end of the first connecting sleeve 41 extending into the second connecting sleeve 44 and threadedly connected to it. When the first connecting sleeve 41 and the second connecting sleeve 44 are threadedly connected, the pulverizing cover 3 can be fixedly clamped between the first connecting sleeve 41 and the second connecting sleeve 44. One end of the rotating shaft 1 is fixedly connected inside the first connecting sleeve 41, and the pulverizing blade 5 is fixed outside the first connecting sleeve 41. The pulverizing cover 3 and the pulverizing blade 5 are driven to rotate synchronously by the rotating shaft 1. That is, in this embodiment, the first connecting sleeve 41 and the second connecting sleeve 44 fix the pulverizing cover 3 between them. At this time, both the pulverizing blade 5 and the pulverizing cover 3 are driven to rotate by the first connecting sleeve 41, thereby improving the uniformity of food pulverization.

[0067] like Figure 6 As shown, the upper end of the first connecting sleeve 41 in this embodiment can be in the shape of a stepped shaft. The crushing cover 3 is sleeved on the upper end of the first connecting sleeve 41 and overlaps on the stepped surface, so as to achieve the clamping and fixing of the crushing cover 3 by the first connecting sleeve 41 and the second connecting sleeve 44.

[0068] In this embodiment, the crushing device also includes a gripper 6, which can be directly formed on the first connecting sleeve 41 or set on the crushing cover 3. Its structural principle is the same as that of Embodiment 1, and will not be described again.

[0069] The remaining structural principles of the food processing machine in this embodiment are the same as those in Embodiment 1, such as the connection structure and working principle between the rotating shaft 1 and the first connecting sleeve 41, which are the same as those in Embodiment 1.

[0070] It should be noted that, considering the excessive load on the motor due to simultaneously rotating both the grinding cover 3 and the grinding blade 5, in this embodiment, the grinding cover 3 can be rotatably positioned between the first connecting sleeve 41 and the second connecting sleeve 44, in addition to being clamped and fixed between them. That is, the first connecting sleeve 41 and the second connecting sleeve 44 do not clamp and fix the grinding cover 3 at this time. Instead, the grinding cover 3 has room to move and can rotate relative to the first connecting sleeve 41, that is, relative to the grinding blade 5. With this structure, the grinding cover 3 can rotate due to the eddy currents generated during food processing, thereby achieving relative rotation with the grinding blade 5. On the one hand, the motor only drives the grinding blade 5 to rotate, avoiding excessive load caused by rotating the grinding cover 3 (if the grinding cover 3 rotates at an excessive speed); on the other hand, the rotation of the grinding cover 3, combined with the rotation of the grinding blade 5, generates stronger eddies, resulting in more uniform food grinding and improved processing efficiency.

[0071] Example 4

[0072] This embodiment provides a food processing machine, which differs from Embodiment 3 in the structure of the connecting sleeve. In this embodiment, as... Figure 7 and Figure 8 As shown, where Figure 7 This is an exploded structural diagram of the pulverizing device of the food processing machine described in Embodiment 4, showing its cooperation with the rotating shaft 1.

[0073] Figure 8 This is a cross-sectional view of the pulverizing device of the food processor described in Embodiment 4, showing its cooperation with the rotating shaft 1. The connecting sleeve of the food processor in this embodiment includes an inner sleeve 43 and a first connecting sleeve 41 fixedly sleeved outside the inner sleeve 43, wherein the first connecting sleeve 41 is located inside the pulverizing cover 3, and the pulverizing blade 5 is fixed outside the first connecting sleeve 41.

[0074] The inner sleeve 43 has a groove 431 on its side wall, which extends circumferentially upward from the bottom of the inner sleeve 43. One end of the rotating shaft 1 extends into the inner sleeve 43, and one end of the rotating shaft 1 has a protrusion 11. The protrusion 11 can slide in the groove 431 and is ultimately confined within the groove 431. On the one hand, this allows the crushing device to be detachably installed on the rotating shaft 1, and also enables the rotating shaft 1 to drive the inner sleeve 43 to rotate, which in turn drives the first connecting sleeve 41, the crushing cover 3, and the crushing blade 5 to rotate, achieving synchronous rotation of the crushing cover 3 and the crushing blade 5. On the other hand, the protrusion 11 is confined within the groove 431. During the operation of the food processing machine, the centrifugal force generated will cause the inner sleeve 43 to tend to move upward. At this time, the protrusion 11 will abut against the inner side wall of the groove 431 to suppress the upward movement of the inner sleeve 43, thereby restricting the inner sleeve 43 from detaching from the rotating shaft 1, and thus restricting the crushing device from detaching from the rotating shaft 1, improving the safety of use.

[0075] In this embodiment, preferably, two slide grooves 431 are provided, and the two slide grooves 431 are symmetrically and through the side wall of the inner sleeve 43. Correspondingly, two protrusions 11 are also provided, and each of the two protrusions 11 is limited to one slide groove 431. Through the cooperation of the two slide grooves 431 and the two protrusions 11, the connection between the crushing device and the rotating shaft 1 is more stable.

[0076] The shape of the groove 431 described above is the same as that of the groove 431 in Embodiment 2, and will not be described again in this embodiment.

[0077] In this embodiment, the connecting sleeve also includes a second connecting sleeve 44, and a crushing cover 3 is installed between the second connecting sleeve 44 and the first connecting sleeve 41. Specifically, as shown... Figure 8 As shown, in this embodiment, the first connecting sleeve 41 is located inside the crushing cover 3. One end of the inner sleeve 43 passes through the first connecting sleeve 41 and the crushing cover 3 and is threadedly connected to the second connecting sleeve 44. Through the threaded connection between the inner sleeve 43 and the second connecting sleeve 44, the crushing cover 3 can be clamped and fixed by the second connecting sleeve 44 and the first connecting sleeve 41, or it can be rotatably disposed between the second connecting sleeve 44 and the first connecting sleeve 41. Its principle and effect are the same as those of the crushing cover 3 installed between the first connecting sleeve 41 and the second connecting sleeve 44 in Embodiment 3, and will not be described again.

[0078] The crushing device in this embodiment also includes a gripper 6. The gripper 6 can be directly formed on the inner sleeve 43 or set on the crushing cover 3. Its structural principle is the same as that in Embodiment 2, and will not be described again.
