The structure includes a sealing cap and a movable cap. The sealing cap has a bean inlet and completely covers the top opening of the integrated container. The movable cap has a movable cap hole and a sealing part and is movably connected to the sealing cap, so that the movable cap hole and the sealing part can be directly opposite the bean inlet. The blade assembly includes a blade drive shaft and a blade fixed on the blade drive shaft. The blade is located inside the integrated container. The bottom end of the blade drive shaft extends from the rotating shaft hole and is connected to the rotating power end of the rotating power device. The water source interface is connected to the water inlet through a water pump, and the passage from the water source interface to the water inlet is a one-way passage from the water source interface to the water inlet. The vacuum pump is connected to the air extraction port.
[0003] The vacuum coffee machine disclosed in CN120240852A uses blades to crush coffee beans and other materials. The blades are usually four in number, and there are differences between the blades due to their functions. The vibration generated when the four blades rotate is relatively large. In addition, in order to crush coffee beans and other materials thoroughly, the blades need to rotate at high speed, which also leads to relatively large vibration.
[0004] Furthermore, replacing the blade-based pulverizing of coffee beans with a grinding mechanism requires the installation of a corresponding limiting cover. This limiting cover necessitates modifications to the feeding structure to ensure its reliability.
[0005] Furthermore, replacing the blade-based pulverizing of coffee beans with a grinding mechanism requires adjusting the position of the grinding element to regulate the particle size. Utility Model Content

Detailed Implementation
[0041] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.
[0042] As a specific embodiment, the food processing apparatus of this utility model includes a container assembly 1, a processing assembly 2, a lifting structure 3, an electrical control device 8, and a carrier assembly 9.
[0043] The electronic control device 8 is a circuit board or similar device of the prior art, which connects to electrical components and is capable of receiving or transmitting electrical signals, thereby controlling one or more of the following: vibration device 14, heating device 18, release valve 19, water pump 4, vacuum pump 5, grinding power device 229 (for motors), and lateral movement power device 328 (for motors). It is readily understood that in embodiments where no electrical components are provided, the electronic control device 8 can be omitted.
[0044] The carrier assembly 9 is used to install and / or place components such as the container assembly 1, the processing assembly 2, and the electronic control device 8. A buffer container 91 for holding food ingredients (such as coffee beans) is provided at the top of the carrier assembly 9. The buffer container 91 is provided with a discharge port 911. When the discharge port 911 is opened, the food ingredients in the buffer container 91 are discharged from the discharge port 911. The specific structure of the buffer container 91 and the discharge port 911 can be the technical solution disclosed in Chinese Invention Patent CN120240852A, or other existing technologies capable of storing and releasing food ingredients.
[0045] Typically, depending on the required processing function, the food processing device is also equipped with functional components 7 with different functions. For example, when the food processing device is used as a coffee machine, the functional component 7 includes a filter device 71 and a coffee pot 72. The filter device 71 includes a drawer 711 and a filter basket 712 on the drawer 711. The drawer 711 can move on the carrier assembly 9 so that the filter basket 712 can be located between the coffee pot 72 and the release valve 19 (described later). Liquid containing coffee grounds flows out from the release valve 19, is filtered by the filter basket 712 to form coffee liquid, and the coffee liquid enters the coffee pot 72.
[0046] The container assembly 1 includes a container part 11 and a container cover 12. The container cover 12 surrounds the container part 11 and is provided with an inlet 121. A release valve 19 is provided at the bottom of the container part 11. It is easy to understand that when the inlet 121, the release valve 19, the water pump 4, and the vacuum pump 5 are all closed, the container cover 12 and the container part 11 form a sealed space.
[0047] As one specific implementation, the container 11 is equipped with at least one of the following: a heating device 18, a water pump 4 connected to a water source such as a water tank 41, and a vacuum pump 5 with one end open to the atmosphere. For example, the heating device 18 is fixed to the bottom of the container 11, and the heating device 18 is usually an existing electric heating device to heat the water and food ingredients inside the container 11. Of course, for food ingredients that do not require heating, the heating device 18 may not be provided. The water pump 4 and the vacuum pump 5 are both fixed on the container cover mounting bracket 129 of the container cover 12. The two ends of the water pump 4 are connected to the water tank 41 and the inner cavity of the container 11, respectively; when it is started, it can inject water into the inner cavity of the container 11. One end of the vacuum pump 5 is open to the atmosphere, and the other end is open to the inner cavity of the container 11; when it is started, it can extract the air from the container 11.
[0048] The processing component 2 includes a grinding component 21, a limiting cover 23, and a drive rod 22 with rotational power.
[0049] The grinding assembly 21 includes a grinding outer ring 212 and a grinding body 211 located within the grinding outer ring 212. The grinding body 211 or the grinding outer ring 212 is drivenly connected to the drive rod 22. In other words, the drive rod 22 can drive the grinding body 211 or the grinding outer ring 212, so that the grinding body 211 can rotate relative to the grinding outer ring 212 within the grinding outer ring 212. The inner sidewall of the grinding outer ring 212 and / or the outer sidewall of the grinding body 211 are provided with grinding teeth (i.e., the higher concept of coarse grinding teeth 213 and fine grinding teeth 214 described later). The grinding body 211 rotates relative to the grinding outer ring 212, which can grind the food raw materials passing between the two, thereby reducing the particle size of the food raw materials.
[0050] The limiting cover 23 is provided with through holes 231. The shape and size of the through holes 231 can be adjusted according to the type of food raw material to be processed, so that the food raw material cannot pass through the through holes 231 and is blocked by the limiting cover 233. For example, when the food raw material is coffee beans, the through holes 231 are strip-shaped and about 3mm wide; multiple through holes 231 are evenly distributed around the axis of the limiting cover 23 and are arranged radially.
[0051] The lifting structure 3 includes a lifting seat 31 with lifting power.
[0052] The limiting cover 23 is fixed relative to the lifting seat 31 and can be inserted into the container 11. The outer wall (or outer edge) of the limiting cover 23 is close to or near the inner wall of the container 11, preventing food ingredients such as coffee beans from passing through the gap between the outer wall of the limiting cover 23 and the inner wall of the container 11. It is easy to understand that when the lifting seat 31 rises and falls, the limiting cover 23, which is fixed relative to the lifting seat 31, also rises and falls with the lifting seat 31, moving out of or into the container 11. It should be noted that the state in which the limiting cover 23 rises and falls within the container 11 but does not move out of the container 11 also constitutes the state in which the limiting cover 23 can be inserted into the container 11.
[0053] The rotation direction of the grinding teeth and the drive rod 22 is configured such that the water flow tends to pass through the gap between the grinding body 211 and the outer grinding ring 212 from below the limiting cover 23 and flow upwards towards the limiting cover 23. For example, the grinding teeth are spiral-shaped, and the rotation direction of the drive rod 22, in conjunction with the spiral-shaped grinding teeth, causes the water flow to tend to pass through the gap between the grinding body 211 and the outer grinding ring 212 from below the limiting cover 23 and flow upwards towards the limiting cover 23.
[0054] The working principle is as follows: During use, coffee beans and other food ingredients are placed into container 11. Due to their own weight, the coffee beans and other food ingredients gather at the bottom of the inner cavity of container 11. Then, the lifting seat 31 and the limiting cover 23 are lowered. The limiting cover 23 confines the coffee beans and other food ingredients within the space formed by the limiting cover 23 and the bottom of the inner cavity of container 11. Then, water is injected into container 11 (water can be added manually or via a water pump 4 connected to a water tank 41 or other water source). The drive rod 22 then begins to rotate, causing... The grinding body 211 or the outer grinding ring 212 rotates, causing water to flow through the gap between the grinding body 211 and the outer grinding ring 212. At the same time, the water flow carries food ingredients such as coffee beans, which tend to pass through the gap between the grinding body 211 and the outer grinding ring 212. When the food ingredients such as coffee beans pass through the gap between the grinding body 211 and the outer grinding ring 212, the grinding teeth grind the food ingredients such as coffee beans, which turns the food ingredients such as coffee beans into smaller particles, such as coffee powder, thus realizing the automatic processing of food ingredients.
[0055] Compared to structures that use blades to pulverize food ingredients such as coffee beans, the grinding teeth are smaller in mass and more numerous. Furthermore, while maintaining the same particle size for pulverizing food ingredients such as coffee beans, the rotation speed requirement for the drive rod 22 is lower, which can reduce overall machine vibration and noise during the automatic processing of food ingredients.
[0056] As one specific implementation, a vibration device 14 is provided on the container 11. The vibration device 14 is a prior art such as a vibration motor, which causes the food ingredients such as coffee beans in the bottom of the inner cavity of the container 11 to vibrate, causing the food ingredients such as coffee beans to collide with each other, which can increase the tendency of the food ingredients such as coffee beans to pass through the gap between the grinding body 211 and the outer grinding ring 212, thereby improving efficiency.
[0057] As one specific implementation, the vibration device 14 is disposed on the bottom end face of the container 11, and the acceleration of the vibration generated by the vibration device 14 has a vector in the height direction. Food ingredients such as coffee beans are vibrated up and down, bouncing up and down at the bottom of the inner cavity of the container 11, which further increases the tendency of the food ingredients such as coffee beans to pass through the gap between the grinding body 211 and the outer grinding ring 212, thereby further improving efficiency. At the same time, since the container 11 is heavier after being filled with water, the vibration device 14 on the bottom end face of the container 11 is located below the water inside the container 11, and its up and down vibration is absorbed by the water inside the container 11, thereby reducing the overall machine vibration during the automatic processing of food ingredients while improving efficiency.
[0058] like Figure 14 As shown, the grinding structure of the food processing apparatus of this utility model includes a container assembly 1 and a processing assembly 2; the container assembly 1 includes a container part 11 and a container cover 12 surrounding the top of the container part 11.
[0059] The processing component 2 includes a grinding component 21, a limiting cover 23, and a drive rod 22 with rotational power.
[0060] The grinding assembly 21 includes a grinding outer ring 212 and a grinding body 211 located inside the grinding outer ring 212. The grinding body 211 is driven to be connected to the drive rod 22. Grinding teeth are provided on the inner side wall of the grinding outer ring 212 and / or the outer side wall of the grinding body 211.
[0061] The limiting cover 23 can be inserted into the container 11. The outer wall of the limiting cover 23 is in contact with or close to the inner wall of the container 11. The rotation direction of the grinding teeth and the drive rod 22 is set so that the water flow tends to pass through the gap between the grinding body 211 and the outer grinding ring 212 from below the limiting cover 23 and flow upward to the limiting cover 23. This embodiment can realize the automatic processing of food raw materials and can also reduce the vibration and noise of the whole machine during the automatic processing of food raw materials.
[0062] As one specific implementation, the grinding teeth include coarse grinding teeth 213 and fine grinding teeth 214. The volume of the fine grinding teeth 214 is smaller than that of the coarse grinding teeth 213, and the coarse grinding teeth 213 are located below the fine grinding teeth 214. This allows for the coarse grinding followed by fine grinding of food ingredients such as coffee beans, thereby improving grinding efficiency.
[0063] As one specific implementation, the inner wall of the grinding outer ring 212 and the outer wall of the grinding body 211 are both provided with grinding teeth. The coarse grinding teeth 213 of the grinding body 211 and the coarse grinding teeth 213 of the grinding outer ring 212, and the fine grinding teeth 214 of the grinding body 211 and the fine grinding teeth 214 of the grinding outer ring 212, all overlap in the height direction. The grinding teeth on the inner wall of the grinding outer ring 212 and the grinding teeth on the outer wall of the grinding body 211 cooperate with each other, which can improve the grinding efficiency and grinding effect of food raw materials such as coffee beans.
[0064] As one specific implementation, the limiting cover 23 is provided with an enclosing body 232, and the grinding outer ring 212 is provided with an anti-rotation surface 219 and is embedded in the enclosing body 232. This implementation can ensure that the grinding outer ring 212 and the limiting cover 23 are firmly fixedly connected.
[0065] As one specific implementation method, the limiting cover 23 is fixedly provided with a rotating connecting seat 233, and the drive rod 22 is rotatably connected to the rotating connecting seat 233. For example, the rotating connecting seat 233 is provided with a bearing (not shown in the figure), and the drive rod 22 is rotatably connected to the rotating connecting seat 233 through the bearing.
[0066] As one specific implementation method, the enclosure 232 is fixedly provided with a limit cover connector 239, and the top end of the limit cover connector 239 is fixedly connected to the lifting seat 31.
[0067] As one specific implementation, there are at least two rotating connecting seats 233. The uppermost rotating connecting seat 233 is fixedly connected to the limiting cover connecting body 239, and the lowermost rotating connecting seat 233 is fixedly connected to the limiting cover 23. The grinding body 211 is located between the uppermost rotating connecting seat 233 and the lowermost rotating connecting seat 233. Even if there are food ingredients such as coffee beans on only one side of the grinding body 211, causing the grinding body 211 to drive the drive rod 22 to tend to bend to the other side (the side opposite to the side with food ingredients such as coffee beans), the uppermost rotating connecting seat 233 and the lowermost rotating connecting seat 233 can ensure that the drive rod 22 will not bend, thereby ensuring that the particle size of the food ingredients such as coffee beans processed by the grinding assembly 21 is relatively uniform.
[0068] As one specific implementation, the lower part of the inner cavity of the grinding outer ring 212 has an overall frustum shape, with a relatively large diameter at the bottom end. This allows food ingredients such as coffee beans to more easily enter the space between the grinding outer ring 212 and the grinding body 211, thereby improving grinding efficiency.
[0069] like Figure 4 As shown, the feeding structure of the food processing apparatus of this utility model includes a container assembly 1, a processing assembly 2, and a lifting structure 3. The container assembly 1 includes a container part 11 and a container lid 12, the container lid 12 surrounding the container part 11 and having a feeding port 121. The lifting structure 3 includes a lifting seat 31 with lifting power. The processing assembly 2 includes a limiting cover 23 fixed relative to the lifting seat 31 and capable of being inserted into the container part 11, the outer side wall of the limiting cover 23 being in contact with or close to the inner side wall of the container part 11. This embodiment ensures that food raw materials such as coffee beans enter below the limiting cover 23.
[0070] As one specific implementation, the container 11 includes a large-area section 111, a small-area section 112, and a guide section 113; the guide section 113 is located between the large-area section 111 and the small-area section 112; the outer wall of the limiting cover 23 is in contact with or close to the inner wall of the small-area section 112; the feed inlet 121 is directly opposite the guide section 113. It is easy to understand that the inner cavity area of the small-area section 112 is smaller than that of the large-area section 111, and the inner wall of the guide section 113 is connected to both the inner wall of the small-area section 112 and the inner wall of the large-area section 111. After the lifting seat 31 drives the limiting cover 23 to rise, food ingredients such as coffee beans falling from the feed inlet 121 avoid the limiting cover 23 and fall onto the guide section 113, where they are guided by the guide section 113 into the small-area section 112; this ensures that food ingredients such as coffee beans enter the small-area section 112 of the container 11, thereby ensuring that all food ingredients such as coffee beans can be processed by the grinding component 21.
[0071] As one specific implementation method, the inner cavity of the large area segment 111 and the inner cavity of the small area segment 112 are both cylindrical, the limiting cover 23 is circular when viewed from above, and the inner cavity of the guide segment 113 is frustum-shaped.
[0072] As one specific implementation, the top surface of the limiting cover 23 is inclined downwards. For example, the top surface of the limiting cover 23 is a frustum-shaped side surface, with a smaller diameter at the top and a larger diameter at the bottom. Even if food ingredients such as coffee beans fall from the feed inlet 121 onto the limiting cover 23, the top surface of the limiting cover 23 can guide the food ingredients to the guide section 113, ensuring that the food ingredients enter the small area section 112 of the container 11, thereby ensuring that the food ingredients such as coffee beans can be processed by the grinding component 21.
[0073] As one specific implementation, the container assembly 1 also includes a sealing cap 13 that completely covers the inlet 121; the container cap 12 is provided with an inlet groove 124, the bottom wall of the inlet groove 124 is an inlet groove bottom wall 125, and the inlet 121 is provided on the inlet groove bottom wall 125. Food ingredients such as coffee beans (usually weighed, etc.) falling from the discharge port 911 of the buffer container 91 enter the inlet groove 124 and are buffered. After the sealing cap 13 is opened, the food ingredients such as coffee beans enter the container 11 from the inlet 121. After the sealing cap 13 is closed, the container 11 and the container cap 12 are sealed; in other words, it is possible to facilitate the entry of food ingredients such as coffee beans into the container 11 while ensuring that the container 11 and the container cap 12 are sealed.
[0074] As one specific implementation method, the bottom wall 125 of the feeding trough is inclined toward the feeding port 121. Food ingredients such as coffee beans are guided into the feeding port 121 by the bottom wall 125 of the feeding trough, which can ensure that all food ingredients such as coffee beans enter the feeding port 121.
[0075] As one specific implementation, the lifting seat 31 is provided with a sealing cover connector 311, and the sealing cover 13 is fixedly connected to the sealing cover connector 311. When the lifting seat 31 drives the limiting cover 23 to rise, the sealing cover 13 also rises with the lifting seat 31, causing the feed inlet 121 to open. At this time, food ingredients such as coffee beans in the feed trough 124 can enter the container 11 through the feed inlet 121. In addition, as mentioned above, food ingredients such as coffee beans can also enter below the limiting cover 23. When the lifting seat 31 drives the limiting cover 23 to fall, the sealing cover 13 also falls with the lifting seat 31, causing the feed inlet 121 to close. At this time, food ingredients such as coffee beans can continue to be stored in the feed trough 124, and the container 11 and the container cover 12 are also sealed. In addition, as mentioned above, the limiting cover 23 limits the food ingredients such as coffee beans below it, so that the food ingredients such as coffee beans can be processed by the grinding component 21. In summary, a single lifting seat 31 (in other words, a single power unit) can control the limit cover 23 and the sealing cover 13, which simplifies the structure and reduces costs.
[0076] As one specific implementation, the lifting seat opening wall 123 is provided with a connecting body groove 312 that avoids the sealing cover connecting body 311. The sealing cover connecting body 311 does not need to bypass the lifting seat opening wall 123, which can reduce the overall height of the lifting seat 31 and the sealing cover connecting body 311 thereon.
[0077] As one specific implementation, the lifting structure 3 also includes a lateral moving member 32 with lateral movement force and a reversing groove 321. The container lid 12 is provided with a lifting seat opening wall 123. The lifting seat 31 is inserted into the lifting seat opening wall 123 and is linearly slidably connected to the container lid 12 during lifting. For example, the lifting slide groove 33 on the container lid 12 cooperates with the lifting slider 331, and / or the lifting seat 31 is inserted into the lifting seat opening wall 123 to achieve a linearly slidable connection between the lifting seat 31 and the container lid 12. Typically, the container lid 12 is provided with a lifting seat opening 122, and the outer edge of the lifting seat opening 122 extends to form the lifting seat opening wall 123. A sealing ring (not shown in the attached figure) is provided on the lifting seat 31 to ensure the sealing between the lifting seat 31 and the lifting seat opening wall 123. One of the lifting seat 31 and the lateral moving member 32 is provided with a reversing groove 321, and the other is provided with a lifting slider 331 inserted into the reversing groove 321. For example, the lifting structure 3 also includes a transverse screw 323. The transverse member 32 is laterally linearly slidably connected to the container lid 12 (the transverse linear slidable connection is achieved through a transverse connection structure 329, such as a slide rail or linear guide). The transverse member 32 is provided with a threaded hole 322. The transverse screw 323, which has rotational power (driven by a transverse force device 328, such as a motor), is screwed into the threaded hole 322, giving the transverse member 32 transverse force. During the transverse movement of the transverse member 32, the inner wall of the deflection groove 321 abuts against the lifting slider 331, causing the lifting seat 31 to rise and fall. No screw or similar device is needed above the lifting seat 31, which reduces the overall height of the lifting seat 31.
[0078] like Figure 9 As shown, the adjustment structure of the food processing device of this utility model includes a processing component 2; the processing component 2 includes a grinding component 21, a limiting cover 23, and a drive rod 22 with rotational power; the grinding component 21 includes a grinding outer ring 212 and a grinding body 211 located inside the grinding outer ring 212, and grinding teeth are provided on the inner sidewall of the grinding outer ring 212 and / or the outer sidewall of the grinding body 211; the grinding outer ring 212 is fixed relative to the limiting cover 23.
[0079] The grinding body 211 is driven and connected to the drive rod 22, and the grinding body 211 can move along the drive rod 22, causing the gap between the grinding body 211 and the outer grinding ring 212 to change. When the gap between the grinding body 211 and the outer grinding ring 212 is small, the particle size of the ground coffee beans and other food raw materials is small; conversely, the particle size of the ground coffee beans and other food raw materials is large. Thus, the particle size of the ground coffee beans and other food raw materials can be adjusted as needed. For example, the outline of the grinding body 211 and the outline of the upper part of the inner cavity of the outer grinding ring 212 are both generally frustum-shaped, but the slope of the sidewalls of the two frustums is different.
[0080] As one specific implementation, the processing component 2 also includes an adjusting member 25 and a driven disk 215. The driving rod 22 includes a threaded section 221. The adjusting member 25 is threadedly connected to the threaded section 221 and abuts against the driven disk 215. The driven disk 215 is provided with a driven disk hole 216 and can be fixed relative to the grinding body 211. For example, the driven disk hole 216 can be integrated with the grinding body 211, so that the grinding body 211 can be rotated by the driven disk 215. Of course, the driven disk 215 can also be fixed relative to the grinding body 211 in a manner described later. The threaded section 221 passes through the driven disk hole 216, allowing the driven disk 215 to slide linearly along the threaded section 221. It is easy to understand that although the driven disk 215 can slide linearly along the threaded section 221, the driven disk 215 cannot rotate around the threaded section 221. For example, the driven disc hole 216 and the threaded section 221 are both racetrack-shaped (i.e., the shape of a circle after the part outside the center is cut off by two parallel straight lines) and have two planar anti-rotation lifting structures 223, which allow the driven disc 215 to slide linearly along the threaded section 221. The rotating adjustment member 25 is used to press against the driven disc hole 216 and the grinding body 211 along the drive rod 22, which can adjust the particle size of the grinding of food raw materials such as coffee beans as needed.
[0081] As one specific implementation, one of the adjusting member 25 and the driven disk 215 is provided with a spring-loaded stop protrusion 251, and the other is provided with a stop groove 252, into which the stop protrusion 251 is inserted. The stop protrusion 251 can be a steel ball held by a spring, or a protrusion made of elastic material such as plastic. When the adjusting member 25 is rotated, the stop protrusion 251 jumps within different stop grooves 252 to achieve the stop effect, thereby allowing the particle size of food raw materials such as coffee beans to be adjusted according to the required stop.
[0082] As one specific implementation, the processing component 2 also includes a locking member 253 and a locking sleeve 254 sleeved on the threaded section 221. The locking member 253 is threadedly connected to the threaded section 221, and the two ends of the locking sleeve 254 abut against the adjusting member 25 and the locking member 253, respectively. Rotating the adjusting member 25 and then rotating the locking member 253 ensures the stability of the position of the adjusting member 25 (along the drive rod 22) after adjustment and ensures a stable grinding effect. Although the locking sleeve 254 can slide linearly along the threaded section 221, it cannot rotate around the threaded section 221 to ensure the transmission of rotational power of the drive rod 22. Of course, the locking sleeve 254 can also rotate around the threaded section 221.
[0083] As one specific implementation, the drive rod 22 also includes a grinding elastic element 24. Both ends of the grinding elastic element 24 are connected to the grinding body 211 and the limiting cover 23, respectively, causing the grinding body 211 to tend to approach the driven disk 215. For example, the grinding elastic element 24 is a spring and sleeved on the drive rod 22. Both ends of the grinding elastic element 24 abut against the lowermost rotating connecting seat 233 and the grinding body 211, respectively, causing the grinding body 211 to tend to approach the driven disk 215. One of the grinding body 211 and the driven disk 215 is provided with a driven disk protrusion 217, which is embedded in the other of the grinding body 211 and the driven disk 215, thus fixing the driven disk 215 relative to the grinding body 211. It is easy to understand that the grinding body 211 can move relative to the driven disk 215 along the drive rod 22. During the grinding process of coffee beans and other food ingredients, the reaction force of the coffee beans and other food ingredients on the grinding body 211 causes the grinding body 211 to bounce up and down relative to the outer grinding ring 212, thereby improving the grinding effect and grinding efficiency.
[0084] As one specific implementation, the drive rod 22 also includes a cylindrical section 222 located below the threaded section 221. The grinding body 211 is sleeved on the cylindrical section 222. It is easy to understand that the cylindrical section 222 alone cannot drive the grinding body 211 to rotate. When the grinding body 211 encounters significant resistance, causing the driven disk protrusion 217 to be pulled out of the grinding body 211 or the driven disk 215, the grinding body 211 rotates around the cylindrical section 222 until the driven disk protrusion 217 re-embeds into the grinding body 211 or the driven disk 215. This prevents the drive rod 22 from jamming (preventing damage to the grinding power device 229 of the motor, etc.) and improves reliability.
