[0026] Reference Figures 1-3In one embodiment, the machine body assembly includes a support base 10, a machine body 11, and a storage bin 12. The machine body 11 is disposed on the support base 10, and the storage bin 12 is disposed at one end of the machine body 11 away from the support base 10, and the machine body 11 and the storage bin 12 are connected.

[0027] In the above embodiment, the machine body assembly includes a support base 10, a main body 11, and a storage bin 12. The support base 10 serves as the bottom base of the device, ensuring that the device is stably placed on a table or countertop during operation. The main body 11 is the central functional load-bearing part of the device, which is directly mounted on the support base 10 and forms a firm connection with it. The storage bin 12 is a container for storing the ingredients to be ground (such as coffee beans, peppercorns, or grains). It is located at the top of the main body 11, that is, at the end of the main body 11 away from the support base 10. The storage bin 12 and the main body 11 are connected by an opening to achieve internal cavity communication, allowing the ingredients in the storage bin 12 to flow smoothly into the internal grinding area of ​​the main body 11 through the opening under gravity.

[0028] The main body 11 and the storage bin 12 are perpendicular to each other. When the equipment is placed on a horizontal table, the main body of the main body 11 remains parallel to the table, while the storage bin 12 extends vertically upwards perpendicular to the table, making full use of vertical space and making it convenient for users to add ingredients from above. The storage bin 12 is located at one end of the top surface of the main body 11 and is close to the location of the adjustment component 4, making the overall structure layout reasonable. This allows users to easily observe and manage the remaining amount of ingredients in the storage bin 12 while operating the adjustment component 4, thus optimizing the functional zoning and improving the convenience of human-computer interaction.

[0029] Reference Figures 1-4 In one embodiment, the main body 11 includes a housing 110 and a drive motor 111, and the fixing component includes a grinding disc fixing member 20 and a first sealing ring 21; The housing 110 is disposed between the support base 10 and the storage bin 12. The drive motor 111 is disposed inside the housing 110. The grinding disc fixing member 20 is disposed inside the housing 110 and communicates with the storage bin 12. The motor output shaft 1111 of the drive motor 111 passes through the grinding disc fixing member 20. The first sealing ring 21 is disposed at one end of the grinding disc fixing member 20 near the drive motor 11 and contacts the housing 110.

[0030] In the above embodiment, the main body 11 includes a housing 110 and a drive motor 111. The fixing components include a grinding disc fixing component 20 and a first sealing ring 21. The housing 110 is the main outer shell of the equipment, which is precisely set between the support base 10 and the storage bin 12. The drive motor 111, as the power source for the grinding action, is firmly installed and fixed in the internal space of the housing 110. The drive motor 111 includes a motor body 1110 and a motor output shaft 1111. The motor output shaft 1111 is connected to one end of the motor body 1110 near the grinding disc assembly. For ease of power supply and operation, the motor body 1110 of the drive motor 111 is electrically connected to a power socket and push-button switch located at one end (rear cover position) of the machine body 110 via a wire. Users can control the start and stop of the motor by plugging and unplugging the power cord and pressing the switch. The grinding disc fixing part 20 is a hollow part with a specific geometric structure. It is placed inside the machine body 110 and communicates with the cavity of the storage bin 12. Its structure is designed with openings at both ends and an opening at the top.

[0031] The central axis of the openings at both ends is completely aligned with the central axis of the motor output shaft 1111 of the drive motor 111, ensuring that the motor output shaft 1111 can smoothly pass through, providing a power transmission channel for the subsequent grinding components. The top opening is perpendicular to the axis of the openings at both ends. This opening is directly connected to the internal cavity of the upper storage bin 12 through a reserved hole on the housing 110, forming a vertical channel for food to enter the grinding area from the storage bin 12. The first sealing ring 21 is set at the corresponding position of the grinding disc fixing member 20. The first sealing ring 21 is set at the end of the grinding disc fixing member 20 near the drive motor 11, and contacts the housing 110. Its function is to form an effective seal when the grinding disc fixing member 20 is connected to other components (such as a detachable grinding disc assembly), preventing fine powder from leaking from the connection gap during the grinding process, and forming a sealed grinding space to prevent powder and liquid leakage, thereby achieving both dry and wet use and ensuring the cleanliness and hygiene of the grinder, maintaining the cleanliness and operating efficiency of the equipment.

[0032] Reference Figures 1-4 In one embodiment, the grinding disc assembly includes a screw body 30 and a screw return spring 31. The screw body 30 is located inside the housing 110, and one end near the drive motor 111 passes through the grinding disc fixing member 20. A spring receiving groove 32 is provided at the end of the screw body 30 near the drive motor 111. The motor output shaft 1111 of the drive motor 111 passes through the spring receiving groove 32 and is connected inside the screw body 30. The screw return spring 31 is sleeved on the motor output shaft 1111 and located inside the spring receiving groove 32.

[0033] In the above embodiment, the grinding disc assembly includes a screw body 30 and a screw return spring 31. The screw body 30 is a key component for conveying food and transmitting grinding power. It has an overall "T"-shaped structure, including a longer screw section and a shorter connecting section. It is located inside the housing 110, specifically at the end near the adjustment component 4. The central axis of the screw body 30 is completely aligned with the central axis of the motor output shaft 1111 of the drive motor 111, and the two are arranged face-to-face to ensure precise power connection. The end of the screw body 30 near the drive motor 111 is designed with a special spring receiving groove 32, and this end passes through the grinding disc fixing component 20. The motor output shaft 1111 of the drive motor 111 further passes through this spring receiving groove 32 and is firmly connected to the screw body 30 (e.g., through spline or key connection), thereby directly transmitting the rotational power of the motor to the screw body 30, driving it to rotate at high speed. The screw return spring 31 is an elastic element that is sleeved on the motor output shaft 1111 and completely housed within the spring receiving groove 32 of the screw body 30. Its installation state is as follows: one end of the spring abuts against the motor body 1110 of the drive motor 111 (or the fixed baffle at the front end of the motor), and the other end abuts against the bottom inner wall of the spring receiving groove 32, placing the screw return spring 31 in a pre-compressed state to provide axial elastic support force for the screw body 30. An appropriate gap is maintained between the outer wall of the screw body 30 and the inner wall of the machine housing 110 to prevent friction during rotation. Spiral feeding ribs are provided on the outer wall of the long screw section of the screw body 30. When the screw body 30 rotates, these ribs act like a spiral shaft, effectively pushing the falling food material towards the grinding area, ensuring a continuous and stable grinding process. Meanwhile, a screw sealing ring is also provided at one end of the screw body 30 near the adjustment component 4, which together with the first sealing ring 21 forms a closed grinding space to prevent powder and liquid from leaking out, thereby achieving both dry and wet use and ensuring the cleanliness and hygiene of the grinder, significantly improving the performance of the grinder and the user experience.

[0034] Reference Figures 1-4 In one embodiment, the grinding disc assembly further includes a front flat grinding disc 33, a rear flat grinding disc 34, and a rear fixing member 35 disposed within the housing 110. The front flat grinding disc 33 is disposed at the end of the screw body 30 away from the adjusting component 4. The rear fixing member 35 is detachably disposed at the end of the grinding disc fixing member 20 away from the drive motor 111. The rear flat grinding disc 34 is disposed at the end of the rear fixing member 35 away from the grinding disc fixing member 20, and the front flat grinding disc 33 and the rear flat grinding disc 34 are disposed at a distance from each other.

[0035] In the above embodiment, the grinding disc assembly also includes a front flat grinding disc 33, a rear flat grinding disc 34, and a rear fixing member 35. The front flat grinding disc 33, the rear flat grinding disc 34, and the rear fixing member 35 are respectively disposed inside the machine body housing 110. The front flat grinding disc 33 and the rear flat grinding disc 34 are key components for realizing the crushing of food. They are arranged opposite each other and maintain an adjustable small gap between them. The food is crushed into powder by compression and shearing force in this gap. The front flat grinding disc 33 is installed at one end of the screw body 30, specifically at the end of the screw body 30 away from the adjusting component 4, and is directly connected to the short rod part of the screw body 30 by fasteners such as bolts. The rear fixing member 35 is detachably installed at one end of the grinding disc fixing member 20, specifically at the end of the grinding disc fixing member 20 away from the drive motor 111. It serves as the mounting base for the rear flat grinding disc 34, which is fixed on the rear fixing member 35 and located on the side of the rear fixing member 35 away from the grinding disc fixing member 20. Therefore, the rear flat grinding disc 34 is indirectly connected to the grinding disc fixing member 20 through the rear fixing member 35.

[0036] Both the front flat grinding disc 33 and the rear flat grinding disc 34 have grinding curved surfaces machined on their opposing working surfaces. These curved surfaces can be concentric circular grooves, radial grooves, or other textures that enhance the grinding effect. The three components—the front flat grinding disc 33, the rear flat grinding disc 34, and the rear fixing member 35—each have a through hole at their center. The central axes of these through holes completely coincide, forming a through channel. The long screw portion of the screw body 30 passes through these three through holes sequentially, connecting the front flat grinding disc 33, the rear fixing member 35, and the rear flat grinding disc 34 in series and maintaining their coaxiality during rotation. The food to be ground, after being pushed by the feed plate ribs of the screw body 30, first passes through the central through holes of the rear fixing member 35 and the rear flat grinding disc 34, and then enters the grinding gap between the front flat grinding disc 33 and the rear flat grinding disc 34, where the final grinding is completed. The ground powder is discharged from the edges of both discs. By mounting the rear flat grinding disc 34 on the detachable rear fixing member 35, convenient maintenance of the core grinding component is achieved. Users can easily remove the rear fixing piece 35 and the rear flat grinding disc 34 connected to it, thereby directly contacting the surface and central through hole of the grinding disc to thoroughly clean the food residue that has accumulated over time, effectively solving the problem of cleaning dead corners and greatly improving cleaning efficiency and hygiene.

[0037] Reference Figures 1-4 In one embodiment, the rear fixing member 35 is provided with a plurality of fasteners 36 at one end near the grinding disc fixing member 20, and the grinding disc fixing member 20 is provided with a plurality of fastening grooves 22 corresponding to the fasteners 36 at one end near the rear fixing member 35, and the rear fixing member 35 is detachably connected to the fastening grooves 22 through the fasteners 36.

[0038] In the above embodiment, the rear fixing member 35 is a component used to support and fix the rear flat grinding disc 34. At one end (i.e., the connecting end) near the grinding disc fixing member 20, it has multiple protruding fastening members 36. These fastening members 36 are evenly distributed along the circumference. As an active connecting element, the grinding disc fixing member 20 is a fixed base inside the equipment. At one end (i.e., the connecting end) near the rear fixing member 35, it has multiple recessed fastening grooves 22. The position and shape of each fastening groove 22 precisely match the fastening members 36 on the rear fixing member 35, ensuring accurate alignment during connection. The fastening groove 22 adopts a preferred L-shaped design, comprising a longer straight groove section and a shorter transverse groove section, which are connected to form an L-shape. On one side of the shorter groove section of the L-shape, an inclined guide surface is designed at its edge.

[0039] During installation, align the latch 36 on the rear fastener 35 with the entrance of the latch groove 22, push the rear fastener 35 in, so that the latch 36 enters the long groove and locks itself in the groove, thus completing the assembly. When disassembly is required, the rear fixing member 35 is rotated in the opposite direction. Rotating the rear fixing member 35 (for example, rotating it clockwise by a certain angle, such as 15-30 degrees) causes the latching member 36 to slide from the long slot into the short slot and be blocked by the side wall of the short slot. Under the action of rotational force, the front end of the latching member 36 will contact the inclined structure on the side of the short slot. Under the continuous applied rotational force, the inclined structure will generate a radial outward component force on the latching member 36, forcing the latching member 36 to slightly deform elastically and disengage from the latching slot 22. This ultimately achieves the rapid separation of the rear fixing member 35 from the grinding disc fixing member 20, making the connection firm and reliable. The disassembly process can be completed by a simple rotation operation without the use of any tools, greatly simplifying the cleaning and maintenance process. Users can remove the rear fixing member 35 (along with the rear flat grinding disc 34) at any time for thorough cleaning.

[0040] Reference Figures 1-4 In one embodiment, the adjustment component 4 includes an adjustment knob 40 and a gear adjustment component 41. The gear adjustment component 41 is located inside the housing 110 and is disposed at the end of the grinding disc assembly away from the drive motor 111. The adjustment knob 40 is disposed at the end of the gear adjustment component 41 away from the grinding disc assembly and is adjustablely connected to the housing 110.

[0041] In the above embodiment, the adjustment component 4 includes an adjustment knob 40 and a gear adjustment component 41. The adjustment knob 40 is an external control component directly operated by the user, typically designed as a round knob easy to rotate with the fingers, located at the front of the device. The gear adjustment component 41 is a transmission and adjustment mechanism hidden inside the housing 110, directly responsible for adjusting the grinding parameters. The gear adjustment component 41 is located at one end of the grinding disc assembly, specifically on the side of the grinding disc assembly away from the drive motor 111, allowing it to directly act on the grinding disc assembly, changing its axial position by pushing or pulling, thereby adjusting the size of the grinding gap. The adjustment knob 40 is located on the outside of the gear adjustment component 41, i.e., at the end of the gear adjustment component 41 away from the grinding disc assembly, forming a linear or coaxial connection chain from the outside to the inside, from the operating end to the executing end.

[0042] The adjustment knob 40 is connected to the housing 110 in an adjustable manner, preferably by a threaded rotation connection. This means that the inner ring of the adjustment knob 40 is threaded, and the housing 110 has a matching threaded hole or threaded sleeve. When the adjustment knob 40 is rotated, due to the meshing of the threads, the adjustment knob 40 will not simply rotate freely, but will generate an axial feed motion (forward or backward). One end of the gear adjustment component 41 is connected to the adjustment knob 40, and the other end is connected to the grinding disc assembly. Therefore, when the user rotates the adjustment knob 40, its axial movement will be converted into a pushing or pulling force on the grinding disc assembly through the gear adjustment component 41, thereby precisely changing the position of the grinding disc assembly and realizing continuous or graded adjustment of the grinding coarseness.

[0043] Reference Figures 1-4 In one embodiment, the adjustment component 4 further includes a limiting member 42, which is disposed on the housing 110 and abuts against the limiting groove 43 of the adjustment knob 40.

[0044] In the above embodiment, an annular limiting groove 43 is machined on the top of the adjusting knob 40. The limiting groove 43 extends continuously along the entire circumference of the adjusting knob 40, forming a closed annular groove. The limiting member 42 is disposed on the housing 110, specifically fixed to the top of the housing 110 by a threaded connection, so that the installation depth of the limiting member 42 can be finely adjusted, thereby precisely controlling its length extending into the housing 110. After installation, a part of the limiting member 42 (i.e., its end or protrusion) is located in the internal space of the housing 110. When the adjusting knob 40 is assembled onto the equipment, the limiting groove 43 on its top is precisely aligned and fitted onto the part of the limiting member 42 located inside the housing 110, so that the part of the limiting member 42 is constrained inside the limiting groove 43. In this assembly relationship, the limiting member 42 and the limiting groove 43 are not rigidly fixed, but allow the adjusting knob 40 to rotate freely within the axial depth of the limiting groove 43. However, when the adjusting knob 40 rotates to the limit position of its designed stroke, the end of the limiting member 42 will contact the end face of the inner wall of the limiting groove 43, forming a physical block. This blocking effect can prevent the adjusting knob 40 from continuing to rotate in that direction, thereby limiting the rotation angle and axial movement range of the adjusting knob 40. The position of the limiting member 42 and the size of the limiting groove 43 together determine the maximum and minimum adjustment positions of the adjusting knob 40, ensuring that the movement of the grinding disc assembly does not exceed its designed safe range, avoiding problems such as grinding disc crushing damage, transmission mechanism jamming, or insufficient grinding gap preventing material discharge due to over-adjustment.

[0045] Reference Figures 1-4 In one embodiment, the gear adjustment component 41 includes a gear adjustment body 410 and an adjustment center shaft 411. The adjustment center shaft 411 is located between the adjustment knob 40 and the grinding disc assembly, and the adjustment center shaft 411 is connected to the adjustment knob 40 and the grinding disc assembly respectively through ball bearings. The gear adjustment body 410 is disposed on the adjustment center shaft 411, and the gear adjustment body 410 is arranged correspondingly to the adjustment knob 40.

[0046] In the above embodiment, the gear adjustment component 41 includes a gear adjustment body 410 and an adjustment center shaft 411. The adjustment center shaft 411 is arranged between the adjustment knob 40 and the grinding disc assembly, serving as a bridge for power and motion transmission. Its two ends are rotatably connected to the adjustment knob 40 and the grinding disc assembly respectively through ball bearings. The gear adjustment body 410 is fixedly connected to the adjustment center shaft 411. The gear adjustment body 410 and the adjustment knob 40 are arranged correspondingly, and the two are tightly fitted in the axial direction but not directly rigidly connected. On the surface or side of the gear adjustment body 410, a plurality of evenly distributed indicator holes are designed. These holes are arranged in the circumferential direction. Correspondingly, a gear adjustment movable part (such as an elastic protrusion or a small steel ball) is provided on the inner side of the adjustment knob 40.

[0047] When the user rotates the adjustment knob 40, due to the threaded connection between the adjustment knob 40 and the housing 110, it will move axially. This axial force is transmitted through the adjustment center shaft 411 and the gear adjustment body 410, ultimately pushing the grinding disc assembly to move axially, thereby changing the grinding gap. During this process, the gear moving part will pass through each indicator hole on the gear adjustment body 410 in sequence when rotating. Whenever the moving part falls into an indicator hole, it will produce a slight elastic deformation and emit a crisp "click" sound. At the same time, the user can feel a clear gear position. A certain gap is maintained between the gear adjustment body 410 and the grinding disc assembly, providing the necessary space for the axial adjustment of the grinding disc assembly. The entire structure achieves low-friction rotation through bearings, achieves precise gear feedback through hole-point fit, and achieves continuous adjustment of the grinding gap through axial transmission, forming a highly efficient adjustment mechanism that integrates precise transmission, clear feedback, and smooth operation.

[0048] Reference Figures 1-4 In one embodiment, the machine body assembly further includes a powder cup 13, the support base 10 includes a base 101 and a support frame 102, the base 101 is connected to the machine body shell 110 through the support frame 102, the end of the machine body shell 110 away from the storage bin 12 is provided with a discharge port corresponding to the grinding disc assembly, and the powder cup 13 is disposed on the base 101 and is arranged corresponding to the powder cup 13.

[0049] In the above embodiment, the machine body assembly also includes a powder cup 13, and the support base 10 includes a base 101 and a support frame 102. The base 101 is the bottom flat support component of the equipment, which directly contacts the table or tabletop. The support frame 102 serves as a connecting component, with one end fixedly connected to the base 101 and the other end connected to the machine body shell 110. It has a curved structure. Through this indirect connection method, the machine body shell 110 is stably mounted above the base 101, forming a suspended support system. The machine body shell 110 is the main outer shell of the equipment. One end of it (the end away from the storage bin 12) is provided with a dedicated discharge port. This discharge port is arranged corresponding to the internal grinding area to ensure that the ground powder can be discharged directly and smoothly.

[0050] The powder receiving cup 13 is a container used to receive and collect the ground powder. It is usually cup-shaped or can-shaped and is set on the base 101. Specifically, it is located directly below the discharge port of the machine body 110 and is arranged correspondingly to the discharge port, so that all the powder falling from the discharge port can fall into the powder receiving cup 13. The powder receiving cup 13 and the base 101 are movable, that is, the powder receiving cup 13 is not fixed to the base 101, but can be freely put in or taken out. The base 101 supports the machine body 110 through the support frame 102. The discharge port on the machine body 110 is vertically aligned with the powder receiving cup 13 on the base 101 below, forming an efficient and closed material output channel from the grinding core to the collection terminal. The height of the support frame 102 determines the space between the machine body 110 and the base 101, providing sufficient operating space for the placement and removal of the powder receiving cup 13.
