Description

Technical Field

[0001] This utility model belongs to the field of grinding product technology, specifically relating to an assembly of a grinding mill hopper and a grinding mill. Background Technology

[0002] Grinders are common auxiliary tools in cooking operations, generally used for fine processing of ingredients, such as grinding seasonings, crushing grains, and processing baby food. Electric grinders generally include a main unit and a container connected to the main unit. The container and the main unit are usually screwed together using a threaded structure.

[0003] For example, Chinese utility model patent CN220212734U discloses a detachable grinder blade assembly, including a housing, a storage tank threaded onto the bottom of the housing, a drive motor fixedly mounted on the bottom of the housing's inner cavity, and a rotating shaft connected to the output shaft of the drive motor. The other end of the rotating shaft passes through the housing and is movably fitted with a movable block. The housing of the main unit and the storage tank (and container) are also threaded together. However, during cooking, consumers' hands are easily covered with oil or water, making it inconvenient to rotate and disassemble the container and the main unit. Furthermore, the storage tank only has a storage function; the blade assembly is mounted on the main unit. After grinding, the container and the main unit still need to be disassembled to obtain the finished product, which is inconvenient for users and has certain limitations. Therefore, further improvement is needed. Utility Model Content

[0004] The purpose of this utility model is to overcome at least one of the shortcomings of the prior art and provide an assembly of a grinding mill hopper and the grinding mill thereof. The hopper can be quickly assembled and disassembled from the hopper seat by moving the hopper in both directions, which is convenient for users. The hopper is only equipped with a hopper lock, which helps to reduce the number of accessories on the hopper, simplify the structure of the hopper and reduce the weight of the hopper, making it convenient for users to use the hopper.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] When the hopper and hopper base are installed, the hopper and hopper lock move forward toward the hopper base. The first lock position passes outside the second lock position. Then, the hopper lock contactes the transmission component and drives the hopper lock to rotate, so that the first lock position corresponds to the second lock position. After the hopper lock retracts in the reverse direction, the first lock position and the second lock position lock together. When the hopper and hopper base are disassembled, the hopper and hopper lock move forward, so that the first lock position moves away from the second lock position. Then, the hopper lock contactes the transmission component and drives the hopper lock to rotate, so that the first lock position and the second lock position are misaligned, and the hopper can be unloaded from the hopper base in the reverse direction.

[0008] In a further embodiment of this utility model, after the hopper and hopper seat are installed, the transmission component, hopper lock component, and seat lock component are arranged sequentially along a straight line.

[0040] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0041] like Figure 1-8 As shown, the assembly of the grinding mill hopper includes a hopper seat 1 and a hopper 2 for storing and grinding materials. The hopper 2 is provided with a hopper lock 3 that can rotate relative to the hopper 2 and has a first locking position 31. The hopper seat 1 is provided with a seat lock 4 that has a second locking position 41 and a transmission component 5 for driving the hopper lock 3 to rotate.

[0042] When the hopper 2 and hopper base 1 are installed, the hopper 2 and hopper lock 3 move forward toward the hopper base 1. The operator moves the hopper 2 forward by pushing it toward the hopper base 1. Figure 1 , 2As shown, in this embodiment, the hopper 2 is assembled from the lower part of the hopper seat 1 upwards onto the hopper seat 1. Therefore, in this embodiment, forward movement should be interpreted as upward movement. The first locking position 31 passes from the outside of the second locking position 41 (the first locking position 31 moves from the head end of the second locking position 41 to the tail end of the second locking position 41; in this embodiment, the head end of the second locking position 41 should be understood as the lower part of the second locking position 41, and the tail end of the second locking position 41 should be understood as the upper part of the second locking position 41). Then, the hopper lock 3 contacts the transmission component 5 and drives the hopper lock 3 to rotate, so that the first locking position 31 corresponds to the second locking position 41. After the hopper lock 3 retracts in the reverse direction (in this embodiment, reverse retraction should be interpreted as upward movement), the hopper lock 3 contacts the transmission component 5 and drives the hopper lock 3 to rotate, so that the first locking position 31 corresponds to the second locking position 41. (This means that when the operator stops pushing the hopper 2 downwards, the hopper 2 will retract in the opposite direction.) The first locking position 31 and the second locking position 41 lock together to achieve quick installation of the hopper 2 and the hopper seat 1. When the hopper 2 is disassembled from the hopper seat 1, the hopper 2 and the hopper lock 3 move forward, so that the first locking position 31 moves away from the second locking position 41. Then the hopper lock 3 contacts the transmission component 5 and drives the hopper lock 3 to rotate, so that the first locking position 31 and the second locking position 41 are misaligned. This allows the first locking position 31 to move from the end of the second locking position 41 to the beginning of the second locking position 41 through reverse retraction. The hopper 2 can then be unloaded from the hopper seat 1 in the opposite direction, achieving quick disassembly of the hopper 2 and the hopper seat 1.

[0043] In this utility model, the hopper 2 can be quickly disassembled and assembled with the hopper seat 1 by moving the hopper 2 in both directions, which is convenient for users. In addition, the hopper 2 is only equipped with the hopper lock 3, and the seat lock 4 and the transmission component 5 are arranged on the hopper seat 1, which helps to reduce the number of accessories on the hopper 2, simplify the structure of the hopper 2 and reduce the weight of the hopper 2, making it more convenient for users to use the hopper 2.

[0044] In some embodiments of this utility model, such as Figure 3 , 4 As shown, after the hopper 2 and the hopper seat 1 are installed, the transmission component 5, the hopper lock component 3, and the seat lock component 4 are arranged in a straight line so that when the hopper 2 and the hopper seat 1 are disassembled, the hopper lock component 3 on the hopper 2 can cooperate with the transmission component 5 by moving in the forward direction.

[0045] In some embodiments of this utility model, such as Figure 1 , 2As shown in Figures 6 and 7, there are several first locking positions 31 and second locking positions 41 arranged at intervals along the circumference. An entry groove 42 is left between two adjacent second locking positions 41 for one first locking position 31 to pass through. The entry groove 42 is set to guide the first locking position 31 to pass through the side of the second locking position 41. The first end of the second locking position 41 is provided with a first guide slope 43 to guide the first locking position 31 to turn into the entry groove 42. When the first locking position 31 moves forward, even if the first end of the second locking position 41 blocks the travel path of the first locking position 31, the first locking position 31 can still be guided to rotate and fall into the entry groove 42 through the contact and cooperation between the first locking position 31 and the first guide slope 43. The second locking position 41 is provided with a locking groove 44 connected to one side of the end of the entry groove 42. The bottom of the locking groove 44 and the first locking position 31 are respectively provided with mutually cooperating first inclined portions 441. The first inclined portions 44 restrict the first locking position 31 from disengaging from the locking groove 44, preventing the first locking position 31 from loosening from the second locking position 41 without human intervention. The height of the first inclined portions 441 gradually decreases from the side of the locking groove 44 connected to the entry groove 42 to the side away from the entry groove 42. The end of the second locking position 41 is provided with a second guide inclined portion 45 located above the locking groove 44. The second guide inclined portion 45 and the entry groove 42 are respectively located on both sides of the locking groove 44. This allows the hopper 2 to be disassembled from the hopper seat 1. When the first locking position 31 retracts in the reverse direction, even if the first locking position 31 deviates slightly and comes into contact with the end of the second locking position 41, the first locking position 31 can still be turned into the corresponding entry groove 42 by the action of the second guide slope 45, thereby realizing the disassembly of the hopper 2 from the hopper seat 1. In this embodiment, the first locking position 31 passes through the entry groove 42 on the side of the second locking position 41 close to the locking groove 44 in the forward direction, and exits in the reverse direction from the entry groove 42 on the side of the second locking position 41 away from the locking groove 44. The height of the second guide slope 45 gradually decreases from the side close to the locking groove 44 to the side away from the locking groove 44.

[0046] In some embodiments of this utility model, such as Figure 1 , 2 As shown in Figures 6 and 7, the first locking position 31 and the second locking position 41 are protrusions provided on the bin locking component 3 and the seat locking component 4, respectively. The protrusions facilitate the cooperation between the bin locking component 3 and the bin seat 1.

[0047] The first locking position 31 and the transmission member 5 are respectively provided with a first inclined surface 32 that cooperates with each other and is used to drive the locking member 3 to rotate. The first inclined surface 32 is provided to realize the adjustment of the circumferential position of the first locking position 31. The transmission member 5 is provided with a number of teeth 51 arranged in sequence along the circumferential direction on the side opposite to the second locking position 41. The side of the teeth 51 opposite to the second locking position 41 constitutes the first inclined surface 32.

[0048] In some embodiments of this utility model, such as Figure 1 , 3As shown in Figures 4 and 7, the hopper seat 1 is equipped with an elastic mechanism. Before the hopper lock 3 moves forward and contacts the transmission component 5, it first contacts the driving elastic mechanism and drives the elastic mechanism to move forward. When the hopper lock 3 contacts the elastic mechanism, the elastic mechanism applies a reverse force to the hopper lock 3. In this case, when the hopper lock 3 and the hopper 2 are not driven forward and are released, the elastic mechanism drives the hopper lock 3 and the hopper 2 to move backward. The setting of the elastic mechanism avoids the hopper lock 3 from contacting the transmission component 5 and causing the hopper lock 3 to rotate without human intervention.

[0049] The elastic mechanism includes a movable member 61 disposed in the hopper seat 1 and used to contact and cooperate with the hopper lock member 3, and a first spring 62 disposed between the hopper seat 1 and the movable member 61. The hopper seat 1 is provided with a range for the movable member 61 to move forward and backward. The movable member 61 is located outside the transmission member 5.

[0050] In some embodiments of this utility model, such as Figure 1 , 3 As shown in Figures 4 and 7, the hopper seat 1 is equipped with a drive device 71, and a coupling structure is provided between the hopper seat 1 and the hopper 2 so that after the hopper seat 1 and the hopper 2 are installed, the drive device 71 drives the hopper 2 to grind powder through the coupling structure.

[0051] The coupling structure includes a seat coupling 72 mounted on the hopper seat 1 and a hopper coupling 73 fixedly connected to the hopper 2. The transmission component 5 is fixedly connected to the seat coupling 72. The transmission component 5 and the seat coupling 72 can be integrally formed to reduce the number of parts. The input end and output end of the seat coupling 72 are respectively connected to the drive device 71 and the hopper coupling 73. The hopper locking component 3 is sleeved on the outside of the hopper coupling 73 and limited between the hopper coupling 73 and the hopper 2. This structure allows the hopper seat 1 and the hopper 2 to be coupled simultaneously after installation.

[0052] In some embodiments of this utility model, such as Figure 1-3 As shown in Figure 7, the hopper seat 1 has a downward-opening receiving cavity 11 for housing the hopper 2. The upper part of the receiving cavity 11 is connected to a docking cavity 12 for coupling structure cooperation. The hopper lock 3, seat lock 4, transmission component 5, elastic mechanism, and coupling structure are located in the docking cavity 12. This structure enables the hopper seat 1 and the hopper 2 to achieve coupling structure cooperation simultaneously after installation.

[0053] In some embodiments of this utility model, such as Figure 2 , 3 As shown in Figures 5, 6, and 8, the hopper 2 includes a container 21 and a cutting tool assembly located at the bottom of the container 21. The hopper 2 is used for both material storage and grinding. The upper part of the cutting tool assembly forms an input end that communicates with the inside of the container 21, and the lower part of the cutting tool assembly forms an output end for the finished product. The finished product can be output without disassembling the hopper 2 and the hopper seat 1. The hopper coupling 73 is fixed to the upper part of the container 21.

[0054] The cutting tool assembly includes a first cover 22 disposed at the bottom of the container 21 and rotating synchronously with the container 21, and a second cover 23 disposed at the bottom of the first cover 22. The container 21 and the first cover 22 form a cavity for storing the raw material to be ground. A limiting structure 24 is provided between the second cover 23 and the hopper seat 1 to prevent the second cover 23 from rotating during the rotation of the container 21. A central blade 25 is provided on the first cover 22, and an annular blade 26 located around the central blade 25 is provided on the second cover 23. The central blade 25 and the annular blade 26 form a grinding zone. During grinding, the container 21, the first cover 22, and the central blade 25 rotate, while the second cover 23 and the annular blade 26 do not rotate. The limiting structure 24 includes a plurality of limiting ribs arranged circumferentially at intervals on the outer side of the second cover 23 and the inner side of the hopper seat 1. When the second cover 23 is disposed on the hopper seat 1, the limiting ribs of the second cover 23 abut against the limiting ribs of the hopper seat 1 circumferentially.

[0055] The first cover 22 and the container 21 are screwed together by a threaded structure, facilitating the assembly and disassembly of the first cover 22 and the container 21. The first cover 22 has a first through hole 221 in the center, and a bracket 222 located on the first through hole 221. The bracket 222 has a mounting shaft 27 passing through the first through hole 221. The central blade 25 is mounted on the mounting shaft 27. The mounting shaft 27 has a second spring 28 located above the central blade 25 and used to push the central blade 25 downward, a limiting platform 271 abutting the top of the second spring 28, and a limiting platform 271 located below the central blade 25 and used to push the central blade 25 downward. An adjusting component 29 for adjusting the height of the central blade 25 is screwed onto the mounting shaft 27 via a threaded structure. The bracket 222 is provided with a mounting hole 2221. The upper part of the mounting shaft 27 is inserted into the mounting hole 2221. The top of the mounting shaft 27 is provided with a fastening position 272 that engages with the top of the bracket 222. The aforementioned structure enables the assembly of the central blade 25 onto the first cover 22 and the height adjustment of the central blade 25 on the mounting shaft 27. The central blade 25 is a conical blade. The fineness of the grinding powder can be changed by adjusting the height of the central blade 25. The mounting shaft 27, the central blade 25, and the first cover 22 rotate synchronously.

[0056] The second cover 23 has a second through hole 231 at its center for the adjustment member 29 and the central knife 25 to pass through. The annular knife 26 is disposed on the upper part of the second through hole 231. A pressure cap 232 located below the first cover 22 is fixed on the second cover 23. The pressure cap 232 presses down and fixes the annular knife 26 between the pressure cap 232 and the second cover 23, thereby realizing the installation of the annular knife 26. A fastening structure 233 is provided between the outer side of the first cover 22 and the inner side of the second cover 23 to enable the first cover 22 and the second cover 23 to be installed and fitted. The fastening structure 233 also facilitates the disassembly and assembly of the first cover 22 and the second cover 23.

[0057] In some embodiments of this utility model, such as Figure 1 , 2 As shown in Figures 3, 4, and 7, the drive device 71 is a motor assembly, and the hopper base 1 is equipped with a battery 81 and a control device 82 that is electrically connected to the battery 81 and the drive device 71.

[0058] The hopper base 1 includes a lower shell 13, an upper shell 14, and an end cap 15 arranged sequentially from bottom to top to form an inner assembly cavity 10. The upper shell 14 forms the gripping position of the grinder. The inner assembly cavity 10 is arranged sequentially from bottom to top to form a cylinder 16, an inner shell 17, and a top frame 18. The receiving cavity 11 is arranged on the cylinder 16. The seat lock 4 is arranged on the upper part of the cylinder 16 and located inside the inner shell 17. The battery 81 and the drive device 71 are arranged on the top frame 18. The seat lock 4 is provided with a mounting bracket 19. The drive device 71 is arranged on the mounting bracket 19 and located inside the inner shell 17 to realize the positioning of the drive device 71. The output end of the drive device 71 is connected to a turntable 711. The seat coupling 72 is fixedly connected to the turntable 711. The elastic mechanism is located between the turntable 711 and the seat lock 4. The upper part of the first spring 62 abuts against the turntable 711 to realize the positioning of the upper part of the first spring 62.

[0059] In some embodiments of this utility model, such as Figure 1-4 As shown in Figures 6 and 7, the lock 3 is annular, and the first lock position 31 is located at the edge of the annular lock 3.

[0060] The top of the container 21 is provided with a boss 211, and the bin coupling 73 is fixed to the boss 211. The first locking position 31 is located outside the bin coupling 73. The boss facilitates the cooperation between the bin locking part 3 and the seat locking part 4, as well as the cooperation of the coupling structure.

[0061] like Figure 1 , 3 As shown in Figures 4 and 7, the seat lock 4 includes an outer cylinder 46 and an inner cylinder 47 connected to the inner side of the outer cylinder 46. The top of the inner cylinder 47 is located below the top of the outer cylinder 46.
