DETAILED DESCRIPTION

[0040] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0041] As a specific embodiment, the food processing device of the embodiment of the present invention includes a container component 1, a processing component 2, a lifting structure 3, an electric control device 8 and a carrier component 9.

[0042] The electronic control device 8 is a conventional circuit board, etc., which is connected to electrical components and can receive or send electrical signals, etc., to control one or more of the vibration device 14, heating device 18, release valve 19, water pump 4, vacuum pump 5, grinding power device 229 (electromechanical), and lateral force device 328 (electromechanical). It will be readily understood that the electronic control device 8 can be omitted in embodiments where no electrical components are provided.

[0043] The carrier assembly 9 is used to mount and / or house components such as the container assembly 1, processing assembly 2, and electronic control device 8. A buffer container 91 for holding food ingredients (such as coffee beans) is located at the top of the carrier assembly 9. This buffer container 91 is provided with a discharge port 911. Upon opening discharge port 911, the food ingredients within the buffer container 91 are discharged through discharge port 911. The specific structure of the buffer container 91 and discharge port 911 can be based on the technical solution disclosed in Chinese invention patent publication CN120240852A, or other existing technologies capable of storing and releasing food ingredients.

[0044] Typically, the food processing device is further provided with functional components 7 having different functions according to the required processing functions. For example, when the food processing device is used as a coffee machine, the functional components 7 include 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 is movable on the carrier assembly 9 so that the filter basket 712 can be positioned between the coffee pot 72 and a release valve 19 to be described later. Liquid containing coffee grounds flows out of the release valve 19, is filtered through the filter basket 712, and forms coffee liquid, which then enters the coffee pot 72.

[0045] The container assembly 1 includes a container 11 and a container lid 12. The container lid 12 surrounds the container 11 and is provided with an inlet 121. The bottom of the container 11 is provided with a release valve 19. 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 lid 12 and the container 11 together form a closed space.

[0046] As one specific embodiment, the container 11 is provided with at least one of 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 connected to the atmosphere. For example, the heating device 18 is fixed to the bottom of the container 11. The heating device 18 is typically a conventional electric heating device, which heats the water and food ingredients within the container 11. Of course, for food ingredients that do not require heating, the heating device 18 can be omitted. The water pump 4 and the vacuum pump 5 are both fixed to the container lid mounting bracket 129 of the container lid 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 activated, it can inject water into the inner cavity of the container 11. The vacuum pump 5 has one end connected to the atmosphere and the other end connected to the inner cavity of the container 11, and when activated, it can extract air from the container 11.

[0047] The processing assembly 2 includes a grinding assembly 21 , a limiting cover 23 and a driving rod 22 with rotational power.

[0048] The grinding assembly 21 includes a grinding outer ring 212 and a grinding body 211 positioned within the grinding outer ring 212. The grinding body 211 or the grinding outer ring 212 is drivingly 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, causing the grinding body 211 to rotate within the grinding outer ring 212 relative to 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 general concept of the coarse grinding teeth 213 and the fine grinding teeth 214 described later). The grinding body 211 rotates relative to the grinding outer ring 212, grinding the food material passing between them and reducing the particle size of the food material.

[0049] The limiting cover 23 is provided with a through-hole 231. The shape and size of the through-hole 231 can be adjusted according to the type of food ingredients to be processed, so that the food ingredients cannot pass through the through-hole 231 and be blocked by the limiting cover 23. For example, if the food ingredients are coffee beans, the through-hole 231 is strip-shaped and has a width of approximately 3 mm. Multiple through-holes 231 are evenly distributed around the axis of the limiting cover 23, forming an overall radial pattern.

[0050] The lifting structure 3 includes a lifting seat 31 with lifting power.

[0051] 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 in contact with or close to 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 is raised or lowered, the limiting cover 23, which is fixed relative to the lifting seat 31, also rises and falls with the lifting seat 31, and is removed from or inserted into the container 11. It should be noted that the state in which the limiting cover 23 is raised or lowered within the container 11 and does not move out of the container 11 also means that the limiting cover 23 can be inserted into the container 11.

[0052] The rotation direction of the grinding teeth and the driving rod 22 is set so that the water flow has a tendency to flow from the bottom of the limiting cover 23 through the gap between the grinding body 211 and the grinding outer ring 212 to the top of the limiting cover 23. For example, the grinding teeth are spiral-shaped, and the rotation direction of the driving rod 22 matches the spiral-shaped grinding teeth so that the water flow has a tendency to flow from the bottom of the limiting cover 23 through the gap between the grinding body 211 and the grinding outer ring 212 to the top of the limiting cover 23.

[0053] The working principle is as follows: when in use, coffee beans or other food materials are placed into the container 11, and the coffee beans or other food materials gather at the bottom of the inner cavity of the container 11 due to their own weight; then the lifting seat 31 and the limiting cover 23 are lowered, and the limiting cover 23 limits the coffee beans or other food materials within the space formed by the limiting cover 23 and the bottom of the inner cavity of the container 11; then water is injected into the container 11 (water can be injected manually or by a water pump 4 connected to a water tank 41 or other water source), and the driving rod 22 starts to rotate, so that The grinding body 211 or the grinding outer ring 212 rotates, causing water to flow through the gap between the grinding body 211 and the grinding outer ring 212. At the same time, the water flow drives food materials such as coffee beans to pass through the gap between the grinding body 211 and the grinding outer ring 212. When the food materials such as coffee beans pass through the gap between the grinding body 211 and the grinding outer ring 212, the grinding teeth grind the food materials such as coffee beans, turning them into smaller particles, such as coffee powder, thereby realizing automatic processing of the food materials.

[0054] Compared with the structure of using blades to crush food ingredients such as coffee beans, the grinding teeth are smaller in mass and more in number, and under the premise of requiring the same particle size of food ingredients such as coffee beans to be crushed, the rotation speed requirement of the driving rod 22 is lower, which can reduce the vibration and noise of the whole machine during the automatic processing of food ingredients.

[0055] As one specific embodiment, the container 11 is provided with a vibration device 14. The vibration device 14 is a conventional vibrating motor. The vibration device 14 vibrates the coffee beans or other food ingredients in the bottom of the inner cavity of the container 11, causing the coffee beans or other food ingredients to collide with each other. This can increase the tendency of the coffee beans or other food ingredients to pass through the gap between the grinding body 211 and the outer grinding ring 212, thereby improving efficiency.

[0056] As one specific embodiment, a vibration device 14 is disposed on the bottom surface of the container 11. The acceleration of the vibration generated by the vibration device 14 has a vector in the height direction. The coffee beans and other food ingredients are vibrated up and down, bouncing up and down at the bottom of the inner cavity of the container 11. This further increases the tendency of the coffee beans and other food ingredients to pass through the gap between the grinding body 211 and the outer grinding ring 212, thereby further improving efficiency. Furthermore, since the container 11 is heavier after being filled with water, the vibration device 14 on the bottom surface of the container 11 is located below the water in the container 11. Its up and down vibrations are absorbed by the water in the container 11, thereby reducing overall vibration during the automatic processing of food ingredients while improving efficiency.

[0057] like Figure 14As shown, the grinding structure of the food processing device according to the embodiment of the present invention 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 end of the container part 11 .

[0058] The processing assembly 2 includes a grinding assembly 21 , a limiting cover 23 and a driving rod 22 with rotational power.

[0059] 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 drivingly connected to the driving rod 22 . The inner side wall of the grinding outer ring 212 and / or the outer side wall of the grinding body 211 are provided with grinding teeth.

[0060] The limiting cover 23 can be inserted into the container 11, with the outer wall of the limiting cover 23 being in contact with or close to the inner wall of the container 11. The grinding teeth and the drive rod 22 are oriented so that water tends to flow from below the limiting cover 23 through the gap between the grinding body 211 and the grinding outer ring 212 to above the limiting cover 23. This embodiment enables the automatic processing of food ingredients and reduces vibration and noise during the automatic processing of food ingredients.

[0061] As one specific embodiment, the grinding teeth include coarse grinding teeth 213 and fine grinding teeth 214. The fine grinding teeth 214 are smaller in volume than the coarse grinding teeth 213, and the coarse grinding teeth 213 are located below the fine grinding teeth 214. This allows food ingredients such as coffee beans to be coarsely ground first and then finely ground, thereby improving grinding efficiency.

[0062] As one specific embodiment, the inner sidewall of the outer grinding ring 212 and the outer sidewall of the grinding body 211 are both provided with grinding teeth. The coarse grinding teeth 213 of the grinding body 211 and the outer grinding ring 212, as well as the fine grinding teeth 214 of the grinding body 211 and the outer grinding ring 212, overlap in height. The grinding teeth on the inner sidewall of the outer grinding ring 212 and on the outer sidewall of the grinding body 211 cooperate with each other to improve the grinding efficiency and effect of food ingredients such as coffee beans.

[0063] As one specific embodiment, the limiting cover 23 is provided with a surrounding body 232, and the grinding outer ring 212 is provided with an anti-rotation surface 219 and embedded in the surrounding body 232. This embodiment can ensure that the grinding outer ring 212 and the limiting cover 23 are firmly fixedly connected.

[0064] As one of the specific implementations, the limit cover 23 is fixedly provided with a rotating connecting seat 233, and the driving rod 22 is rotatably connected to the rotating connecting seat 233. For example, a bearing is provided on the rotating connecting seat 233 (not marked in the drawings), and the driving rod 22 is rotatably connected to the rotating connecting seat 233 through the bearing.

[0065] As one of the specific implementations, the surrounding body 232 is fixedly provided with a limiting cover connecting body 239 , and the top end of the limiting cover connecting body 239 is fixedly connected to the lifting seat 31 .

[0066] As one specific embodiment, there are at least two rotating connectors 233, with the uppermost rotating connector 233 fixedly connected to the limit cover connector 239, and the lowermost rotating connector 233 fixedly connected to the limit cover 23. The grinding body 211 is located between the uppermost and lowermost rotating connectors 233. Even if food materials such as coffee beans are present on only one side of the grinding body 211, the grinding body 211 drives the drive rod 22 to have a tendency to bend toward the other side (the side opposite the side with the coffee beans or other food materials). The uppermost and lowermost rotating connectors 233 ensure that the drive rod 22 does not bend, thereby ensuring that the particle size of the coffee beans or other food materials processed by the grinding assembly 21 is relatively uniform.

[0067] As one specific embodiment, the lower portion of the inner cavity of the grinding outer ring 212 is truncated in shape, with a larger diameter at the bottom end of the truncated cone. This allows food ingredients such as coffee beans to more easily enter between the grinding outer ring 212 and the grinding body 211, thereby improving grinding efficiency.

[0068] like Figure 4 As shown, the feeding structure of a food processing device according to an embodiment of the present invention includes a container assembly 1, a processing assembly 2, and a lifting structure 3. Container assembly 1 includes a container 11 and a container lid 12. The container lid 12 surrounds container 11 and is provided with an inlet 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 container 11. The outer wall of the limiting cover 23 is in contact with or close to the inner wall of the container 11. This embodiment ensures that food ingredients such as coffee beans enter under the limiting cover 23.

[0069] As one specific embodiment, 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 aligned with or close to the inner wall of the small-area section 112. The feed inlet 121 faces the guide section 113. As can be readily understood, 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 connects to the inner walls of the small-area section 112 and the inner walls of the large-area section 111, respectively. After the lifting seat 31 drives the limiting cover 23 upward, coffee beans and other food ingredients falling from the feed inlet 121 avoid the limiting cover 23 and fall onto the guide section 113. Thereafter, guided by the guide section 113, they fall into the small-area section 112. This ensures that the coffee beans and other food ingredients enter the small-area section 112 of the container 11, thereby ensuring that they can be processed by the grinding assembly 21.

[0070] As one of the specific implementations, the inner cavities of the large area segment 111 and 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 truncated cone-shaped.

[0071] As one specific embodiment, the top surface of the limiting cover 23 is tilted downward. For example, the top of the limiting cover 23 has a truncated cone-shaped side surface, with the top circular portion of the truncated cone having a smaller diameter and the bottom circular portion having a larger diameter. Even if coffee beans or other food ingredients falling from the feed inlet 121 land on the limiting cover 23, the top surface of the limiting cover 23 can guide the coffee beans or other food ingredients to the guide section 113, ensuring that the coffee beans or other food ingredients enter the small area section 112 of the container 11, thereby ensuring that the coffee beans or other food ingredients are processed by the grinding assembly 21.

[0072] As one specific embodiment, the container assembly 1 further includes a sealing cover 13 that completely blocks the feed opening 121. The container cover 12 is provided with a feed chute 124, the bottom wall of which is the feed chute bottom wall 125, and the feed opening 121 is provided on the feed chute bottom wall 125. Coffee beans and other food ingredients (usually weighed, etc.) that fall from the discharge port 911 of the buffer container 91 enter the feed chute 124 and are buffered. After the sealing cover 13 is opened, the coffee beans and other food ingredients enter the container 11 through the feed opening 121. After the sealing cover 13 is closed, the container 11 and the container cover 12 are sealed. In other words, the container 11 and the container cover 12 are sealed, while ensuring that the container 11 and the container cover 12 are sealed.

[0073] As one specific embodiment, the feed chute bottom wall 125 is inclined toward the feed inlet 121. The coffee beans and other food materials are guided into the feed inlet 121 by the feed chute bottom wall 125, ensuring that all the coffee beans and other food materials enter the feed inlet 121.

[0074] As one of the specific embodiments, 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, so that the feed port 121 is opened. At this time, the coffee beans and other food ingredients in the feed chute 124 can enter the container 11 from the feed port 121. In addition, as mentioned above, the coffee beans and other food ingredients can also enter the bottom of the limiting cover 23. When the lifting seat 31 drives the limiting cover 23 to descend, the sealing cover 13 also descends with the lifting seat 31, so that the feed port 121 is closed. At this time, the feed chute 124 can continue to store coffee beans and other food ingredients, and the container 11 and the container cover 12 are also sealed. In addition, as mentioned above, the limiting cover 23 limits the coffee beans and other food ingredients below it, so that the coffee beans and other food ingredients can be processed by the grinding assembly 21. In summary, only one lifting seat 31 (in other words, only one power device) can control the limiting cover 23 and the sealing cover 13, which can simplify the structure and reduce costs.

[0075] As one specific embodiment, the lifting seat opening wall 123 is provided with a connector groove 312 for avoiding the sealing cover connector 311. The sealing cover connector 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 connector 311 thereon.

[0076] As one specific embodiment, the lifting structure 3 also includes a transverse member 32 having a transverse movement force and a direction-changing groove 321. The container cover 12 is provided with a lifting seat opening wall 123. The lifting seat 31 is snugly inserted into the lifting seat opening wall 123 and is connected to the container cover 12 in a linear sliding manner. For example, the lifting slot 33 on the container cover 12 cooperates with the price-raising slider 331, and / or the lifting seat 31 is snugly inserted into the lifting seat opening wall 123 to achieve a linear sliding manner between the lifting seat 31 and the container cover 12. Typically, the container cover 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 drawings) is provided on the lifting seat 31 to ensure sealing between the lifting seat 31 and the lifting seat opening wall 123. One of the lifting seat 31 and the transverse member 32 is provided with a direction-changing groove 321, and the other is provided with a price-raising slider 331 inserted into the direction-changing groove 321. For example, the lifting structure 3 also includes a transverse screw 323. The transverse member 32 is connected to the container cover 12 in a transverse linear sliding manner (the transverse linear sliding connection is achieved through a transverse connecting structure 329 such as a slide groove or linear guide rail). The transverse member 32 is provided with a threaded hole 322. The transverse screw 323 with rotational power (driven by a transverse force device 328 such as a motor to provide rotational power) is screwed into the threaded hole 322, thereby providing the transverse member 32 with transverse force. During the transverse movement of the transverse member 32, the inner wall of the direction-changing groove 321 abuts against the price-raising slider 331, causing the lifting base 31 to rise and fall. Without the need for a screw or the like above the lifting base 31, the overall height of the lifting base 31 can be reduced.

[0077] like Figure 9 As shown, the adjustment structure of the food processing device of an embodiment of the present invention includes a processing component 2; the processing component 2 includes a grinding component 21, a limiting cover 23 and a driving rod 22 with rotational power; the grinding component 21 includes a grinding outer ring 212 and a grinding body 211 located in the grinding outer ring 212, and the inner wall of the grinding outer ring 212 and / or the outer wall of the grinding body 211 are provided with grinding teeth; the grinding outer ring 212 is fixed relative to the limiting cover 23.

[0078] The grinding body 211 is drivably connected to the drive rod 22 and can move along the drive rod 22, thereby varying the gap between the grinding body 211 and the grinding outer ring 212. When the gap between the grinding body 211 and the grinding outer ring 212 is smaller, the particle size of the ground coffee beans or other food ingredients is smaller; conversely, when the gap between the grinding body 211 and the grinding outer ring 212 is smaller, the particle size of the ground coffee beans or other food ingredients is larger. Thus, the particle size of the ground coffee beans or other food ingredients can be adjusted as needed. For example, the contours of the grinding body 211 and the upper portion of the inner cavity of the grinding outer ring 212 are both generally truncated cones, but the slopes of the sidewalls of the two truncated cones differ.

[0079] As one of the specific embodiments, the processing assembly 2 further 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 driven disk 215 drives the grinding body 211 to rotate. Of course, the driven disk 215 can also be fixed relative to the grinding body 211 in the manner described below. 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 disk hole 216 and the threaded section 221 are both racetrack-shaped (i.e., a circle with two parallel lines cutting off the portion outside the center), and are equipped with two planar anti-rotation lifting structures 223, allowing the driven disk 215 to slide linearly along the threaded section 221. By rotating the adjusting member 25, the adjusting member 25 abuts against the driven disk hole 216 and the grinding body 211 along the drive rod 22, thereby adjusting the particle size of the ground food material, such as coffee beans, as needed.

[0080] As one specific embodiment, one of the adjusting member 25 and the driven disk 215 is provided with a resilient shifting protrusion 251, and the other is provided with a shifting groove 252, into which the shifting protrusion 251 is inserted. The shifting protrusion 251 can be a spring-loaded steel ball or a protrusion made of an elastic material such as plastic. When the adjusting member 25 is rotated, the shifting protrusion 251 bounces within different shifting grooves 252, achieving a shifting effect. This allows the particle size of the ground food material, such as coffee beans, to be adjusted as needed.

[0081] As one specific embodiment, the processing assembly 2 also includes a locking member 253 and a locking sleeve 254 that is 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 are respectively against the adjusting member 25 and the locking member 253. Rotating the adjusting member 25 and then rotating the locking member 253 can ensure that the position of the adjusting member 25 after adjustment (the position along the drive rod 22) is stable and the grinding effect is stable. Although the locking sleeve 254 can slide linearly along the threaded section 221, the locking sleeve 254 cannot rotate around the threaded section 221 to ensure the transmission of the rotational power of the drive rod 22. Of course, the locking sleeve 254 can also rotate around the threaded section 221.

[0082] As one specific embodiment, the drive rod 22 further includes a grinding elastic member 24; the two ends of the grinding elastic member 24 are respectively connected to the grinding body 211 and the limiting cover 23, so that the grinding body 211 has a tendency to approach the driven disk 215. For example, the grinding elastic member 24 is a spring and is mounted on the drive rod 22. The two ends of the grinding elastic member 24 respectively abut against the lowermost rotating connection seat 233 and the grinding body 211, so that the grinding body 211 has a tendency 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, thereby 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. When the grinding assembly 21 is grinding food materials such as coffee beans, the reaction force of the coffee beans and other food materials on the grinding body 211 causes the grinding body 211 to jump up and down relative to the grinding outer ring 212, thereby improving the grinding effect and grinding efficiency.

[0083] As one specific embodiment, the drive rod 22 further 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 withdrawn from 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 is re-engaged with the grinding body 211 or the driven disk 215. This prevents the drive rod 22 from getting stuck (preventing damage to the grinding power device 229 of the motor, etc.) and improves reliability.
