[0027] The following detailed description refers to the drawings that form a part of this specification. The exemplary embodiments mentioned in the specification and drawings are for illustrative purposes only and are not intended to limit the scope of protection of this application. In light of this application, those skilled in the art will understand that many other embodiments can be adopted and various changes can be made to the described embodiments without departing from the subject matter and scope of protection of the utility model. It should be understood that the various aspects of the present application described and illustrated herein can be arranged, replaced, combined, separated and designed according to many different configurations, and these different configurations are all within the scope of protection of this application.

[0028] The present invention provides a grinding device, which can grind an object to be ground into powder for subsequent use. Preferably, the grinding device provided by the present invention is a tea grinding device, and the object to be ground is tea.

[0029] See also Figures 1 to 3 The grinding device provided by the present invention includes a tool assembly 10, a drive assembly 40 and a material box 20.

[0030] The tool assembly 10 may include a tool and a grinding chamber. The tool may include a movable tool 11 and a fixed tool 12. Both the movable tool 11 and the fixed tool 12 may be annular, with the grinding chamber formed by the cavity between the movable tool 11 and the fixed tool 12. In this embodiment, the tool assembly 10 may be a conical tool assembly or a disc-shaped tool assembly, with grinding teeth disposed on the opposing surfaces of the movable tool 11 and the fixed tool 12.

[0031] The drive assembly 40 is in transmission connection with the movable cutter 11 to drive the movable cutter 11 to rotate. Rotation of the movable cutter 11 relative to the fixed cutter 12 grinds the material in the grinding chamber into powder. The grinding apparatus may also include a powder outlet, through which the powder ground by the cutter assembly 10 can be discharged for use.

[0032] The material box 20 is used to hold the material to be ground, which may be tea leaves. A discharge port 21 is provided at the bottom of the material box 20, communicating with the grinding chamber. The material in the material box 20 enters the grinding chamber through the discharge port 21, where it is then ground into powder by the cutter assembly 10. The inner wall of the bottom of the material box 20 is tilted to facilitate the flow of the material along the inner wall of the material box 20 into the discharge port 21.

[0033] In this embodiment, the grinding device further includes a feeding member 30, which includes a rod body 31 and a paddle 32 arranged on the circumference of the rod body 31. The feeding member 30 is used to transfer the material to be ground in the material box 20 to the grinding chamber.

[0034] In this embodiment, the output shaft of the drive assembly 40 is in driving connection with the tool assembly 10 and the feed member 30. The tool assembly 10 further includes a tool mounting base 13, to which the movable tool 11 is fixedly mounted. The feed member 30 includes a mounting base 33, which is mounted within the grinding chamber and fixed to the tool mounting base 13. The drive assembly 40 is in driving connection with the tool mounting base 13, driving the tool mounting base 13 to rotate, thereby synchronously driving the movable tool and the feed member 30 to rotate.

[0035] Of course, in other embodiments provided by the present invention, two sets of drive assemblies 40 may also be provided, respectively for driving the movable tool 11 and the feeding member 30 , and the two sets of drive assemblies 40 may work synchronously.

[0036] The grinding device also includes a material dispensing member 50. The material dispensing member 50 is installed in the material box 20. In this application, the end of the material box 20 where the material outlet 21 is located is referred to as the bottom, and the side opposite the material outlet 21 is referred to as the top. In one embodiment of the present invention, the top of the material box 20 may be provided with an inlet, through which the user can add the material to be ground into the material box 20.

[0037] The output shaft of the driving assembly 40 is in transmission connection with the tool assembly 10 and the feeding member 30 . The driving assembly 40 is used to drive the feeding member 30 and the tool assembly 10 to move synchronously, and to drive the material shifting member 50 to move.

[0038] In this embodiment, driving the material shifting member 50 to move can be driving the material shifting member 50 to move as a whole or in part relative to the material box 20, such as driving the material shifting rod 50 to swing, or driving part of the material shifting rod 50 to move relative to other parts, such as undergoing elastic deformation.

[0039] The force of the drive assembly 40 can be transmitted to the feed member 30 and the material tapping member 50. In this embodiment, the drive assembly 40 can drive the feed member 30 to rotate, and transmit the driving force to the material tapping member 50 through the feed member 30, thereby driving the material tapping member 50 to move. In other embodiments provided by the present invention, the drive assembly 40 can also directly drive the material tapping member 50 to move. For example, the material tapping member 50 is directly fixed to the output shaft, so that when the output shaft rotates, the material tapping member 50 can be driven to rotate, and the material tapping member 50 is a flexible structure, so that when the material tapping member 50 rotates, it can also cover its radial area.

[0040] The feed member 30 and the prying member 50 can provide different stirring forces. Especially when the material to be ground is tea leaves, which are slender and prone to curling and accumulating, the feed member 30 ensures stable grinding of the tea leaves within the grinding chamber, preventing the tea leaves from accumulating above the grinding chamber during the grinding process and preventing them from entering the grinding chamber, causing the cutter assembly 10 to idle. The prying member 50 installed in the material box 20 can further stir the material to be ground within the material box 20, preventing it from accumulating inside the material box 20.

[0041] Thus, the grinding device is provided with both the feed member 30 and the material shifting member 50, which can increase the speed at which the material to be ground in the material box 20 is transported to the grinding chamber, thereby improving grinding efficiency. Furthermore, the use of the same drive assembly 40 to simultaneously drive the feed member 30 and the material shifting member 50 can fully utilize the power of the drive assembly 40, and the overall structure is simple and compact.

[0042] In one embodiment of the present invention, the paddle 32 can be directly connected to the material diverter 50, and the driving assembly 40 drives the paddle 32 to rotate to directly drive the material diverter 50 to move, such as the free end of the paddle 32 is directly connected to the material diverter 50. That is, the paddle 32 and the material diverter 50 move and stop at the same time.

[0043] In other embodiments of the present invention, there may not be a direct connection between the paddle 32 and the material diverter 50. In this embodiment, the paddle 32 can interfere with the material diverter 50 to transmit the driving force of the drive assembly 40 to the material diverter 50, thereby driving the material diverter 50. In other words, the paddle 32 and the material diverter 50 are not directly connected together, but are provided separately. The drive assembly 40 first drives the paddle 32 to move, and then the paddle 32 drives the material diverter 50 to move.

[0044] When the driving assembly 40 drives the feeding member 30 to rotate, the paddle 32 may interfere with the material diverter 50. Specifically, the paddle 32 may periodically interfere with the material diverter 50 to drive the material diverter 50 to move and / or elastically deform the material diverter 50, so that the material diverter 50 changes between an interfering state with the paddle 32 and a non-interfering state without interfering with the material diverter 50.

[0045] There can be multiple paddles 32, and during the rotation of the feeder 30, at least some of the paddles 32 can interfere with the feeder 50. There can be multiple paddles 32 that can interfere with the feeder 50, and the multiple paddles 32 can be spaced circumferentially along the rod 31 of the feeder 30. During each rotation of the feeder 30, the multiple paddles 32 can sequentially interfere with the feeder 50.

[0046] In the embodiment provided by the present invention, during the rotation of the feed member 30, when the material diverter 50 is not in contact with the paddle 32, the material diverter 50 is not subjected to external forces and is in a non-interference state. When the feed member 30 rotates until one of the paddles 32 contacts the material diverter 50, the feed member 30 rotates further, and the driving force of the drive assembly 40 is transmitted to the material diverter 50 through the paddle 32, causing the material diverter 50 to move. At this point, the material diverter 50 is in an interference state. If the feed member 30 further rotates a certain angle, the material diverter 50 can break away from the interference with the paddle 32 and return to a non-interference state.

[0047] It will be appreciated that during the rotation of the feed member 30, the feed member 50 periodically changes between the interfering and non-interfering states. For example, if only one of the paddles 32 interferes with the feed member 50 during one rotation of the feed member 30, the feed member 50 changes between the interfering and non-interfering states once for each rotation of the feed member 30. On the other hand, if two of the paddles 32 interfere with the feed member 50 during one rotation of the feed member 30, the feed member 50 changes between the interfering and non-interfering states twice for each rotation of the feed member 30.

[0048] For further information, see Figures 3 to 7 In one embodiment of the present invention, the material diverter 50 can extend from the top to the bottom of the material box 20 within the material box 20. The bottom end of the material diverter 50 is a free end. The bottom end of the material diverter 50 is closer to the bottom end of the rod body 31 relative to at least some of the diverter blades 32. In the radial direction of the feeder 30, the material diverter 50 is closer to the rod body 31 relative to the free ends of at least some of the diverter blades 32.

[0049] In this way, during the rotation of the feeding member 30 , at least a portion of the paddles 32 may interfere with the material-diverting member 50 .

[0050] Since the bottom end of the material-digging member 50 is a hanging free end, the material-digging member 50 is more likely to move under the action of the diverter blade 32. And when the bottom end of the material-diverter 50 is out of interference with the diverter blade 32, the material-diverter 50 is more likely to return to its initial state when it does not interfere with the diverter blade 32.

[0051] During the movement of the material-moving member 50 , an external force can be applied to the materials to be ground inside the material box 20 to promote their separation and reduce accumulation.

[0052] Furthermore, in one embodiment of the present invention, the bottom end of the material moving rod 50 is made of elastic material.

[0053] During the rotation of the feed member 30, when the paddle 32 interferes with the material diverter 50, the feed member 30 rotates further, and the driving force of the drive assembly 40 can be transmitted to the material diverter 50 via the paddle 32, causing the bottom end of the material diverter 50 to elastically deform. When the feed member 30 rotates to a certain angle, the material diverter 50 and the paddle 32 are no longer interfering, and the elastic force of the material diverter 50 is released, returning to a non-interfering state. When the material diverter 50 changes between the interfering state and the non-interfering state, the elastic force of the material diverter 50 is released, causing the material diverter 50 to vibrate, thereby applying external force to the material to be ground accumulated in the material box 20, promoting its movement toward the discharge port 21.

[0054] In this embodiment, the material diverter rod 50 can be entirely made of an elastic material. During the rotation of the feed member 30, the interference between the feed member 30 and the material diverter 50 can drive the entire material diverter 50 to move. Specifically, when the feed member 30 interferes with the material diverter 50 and transmits driving force to the material diverter 50, the material diverter 50 can undergo elastic deformation as a whole. This can increase the range of motion of the material diverter 50, thereby increasing the range of force applied to the material to be ground in the material box 20 and preventing the material to be ground from accumulating in the material box 20. In addition, the material diverter rod 50 is entirely made of an elastic material, which is also more convenient to process and manufacture.

[0055] Further, in one embodiment of the present invention, see Figure 4 、 Figure 5 , a connecting member 22 is provided in the material box 20. The connecting member 22 can be provided near the top of the material box 20, and the top end of the material digging member 50 can be connected to the connecting member 22. The material digging member 50 has a rotational freedom relative to the connecting member 22, see Figure 7 The rotation axis X2 of the material-diverting member 50 is parallel to the plane formed by the rotation axis X1 of the feeding member 30 and the material-diverting member 50 .

[0056] In this embodiment, when the material-diverting member 50 is in a non-interference state, the length direction of the material-diverting member 50 is parallel to the rotation axis X1 of the feeding member 30 , and the material-diverting member 50 and the rotation axis X1 of the feeding member 30 form a plane.

[0057] The material-diverting member 50 has a free end that rotates relative to the connecting member 22 about the rotation axis X2. That is, the material-diverting member 50 can rotate relative to the connecting member 22 along the rotation axis X2. During the rotation of the feed member 30, when the paddle 32 rotates until it contacts the material-diverting member 50, the paddle 32 applies a force perpendicular to the rotation axis X2 to the material-diverting member 50. Because the top end of the material-diverting member 50 has the degree of rotational freedom to rotate along the rotation axis X2, the external force applied by the paddle 32 allows the material-diverting member 50 to easily swing about the rotation axis X2.

[0058] When the feeder 30 rotates until the paddle 32 contacts the feeder 50, the feeder 30 rotates further, causing the paddle 32 to interfere with the feeder 50. The paddle 32 applies an external force to the feeder 50, causing the feeder 50 to swing. During the rotation of the feeder 30, the feeder 50 rests on the paddle 32, and the paddle 32 and the feeder 50 slide relative to each other. After the feeder 30 rotates a certain angle, the free end of the paddle 32 passes over the feeder 50 and separates from the feeder 50, thereby freeing the feeder 50 from interfering with the paddle 32.

[0059] Furthermore, in one embodiment of the present invention, the material-moving member 50 and the connecting member 22 are clearance-fitted.

[0060] See also Figure 4 、 Figure 5 In this embodiment, the connecting member 22 may include a connecting rod 25 connected to the material-displacing member 50. The connecting rod 25 may extend along the rotation axis X2. The material-displacing member 50 may have a clearance fit with the connecting rod 25. The material-displacing member 50 may move relative to the connecting rod 25, such as rotating relative to the connecting rod 25 or moving along the extension direction of the connecting rod 25.

[0061] With such a configuration, during the interference between the paddle 32 and the material-pickup member 50, the paddle 32 applies an external force to the material-pickup member 50, and the top end of the material-pickup member 50 can be displaced relative to the connecting member 22 under the action of the force. In this way, the material-pickup member 50 is more likely to swing, and when the paddle 32 rotates a certain angle, the bottom end of the material-pickup member 50 is more likely to disengage from the interference with the paddle 32, avoiding jamming.

[0062] In this embodiment, the material diverter 50 is detachably connected to the connecting member 22. Specifically, the material diverter 50 can be suspended from the connecting rod 25. The material diverter 50 can have an elastic buckle 51 with an opening toward the bottom end, and the material diverter 50 can be directly and detachably connected to the connecting rod 25 through the elastic buckle 51.

[0063] In this way, the user can conveniently remove the material-digging member 50 for cleaning or replace it with a new one. At the same time, the connection between the material-digging member 50 and the connecting member 22 is relatively firm through the elastic buckle 51, and the bottom end of the material-digging member 50 is made of elastic material. Therefore, when the material-digging member 50 moves, the part near the top end of the material-digging member 50 has a relatively small range of movement, while the part near the bottom end of the material-digging member 50 has a relatively large range of movement. This not only prevents the material to be ground from accumulating in the material box 20, but also makes it less likely for the user to be injured by the relatively small top end of the material-digging member 50.

[0064] Furthermore, in one embodiment of the present invention, the connecting member 22 includes a grille member installed on the top of the material box 20 , and the grille member is used to cover the discharge port 21 .

[0065] In this embodiment, the grille member can cover the feed inlet or be located between the feed inlet and the discharge port 21. The grille member can be used to prevent hands from reaching into the grinding chamber through the discharge port 21, reducing safety hazards. The material shifting member 50 can be directly connected to the grille member, eliminating the need for a separate connector 22, avoiding increased costs and reducing the internal volume of the material box 20.

[0066] Furthermore, in one embodiment of the present invention, the grinding device further includes a material discharge channel 61 connecting the discharge port 21 and the grinding chamber. The feed member 30 is at least partially disposed within the material discharge channel 61. The material box 20 further includes a material door 23 for opening and closing the discharge port 21. In the direction of the rotation axis X1 of the feed member 30, the material door 23 is closer to the top of the material box 20 than the feed member 30. A material dispensing member 50 is detachably connected to the material box 20.

[0067] In this embodiment, the material door 23 is rotatably connected to the material box 20. The material box 20 is also equipped with a drive rod 24, one end of which is connected to the material door 23. The user can drive the drive rod 24 to open and close the material door 23. The feed member 30 is completely located within the grinding chamber and the blanking channel 61 and does not extend into the interior of the material box 20. Therefore, the feed member 30 does not interfere with the material door 23. However, because the material prying member 50 can interfere with the prying blade 32, the material prying member 50 will pass through the discharge port 21 of the material box 20 and enter the blanking channel 61. Therefore, the material prying member 50 will affect the opening and closing of the material door 23. In this way, the material prying member 50 is detachably connected to the material box 20. When the user needs to close the material door 23, the material prying member 50 can be removed first and then the material door 23 is closed.

[0068] In this embodiment, since the material box 20 needs to be cleaned or maintained during long-term use, the material box 20 is usually detachable. When the user needs to remove the material box 20, the material door 23 needs to be closed first to prevent the material to be ground in the material box 20 from leaking out.

[0069] In this embodiment, there are many advantages by providing a detachable material-dispensing member 50: first, the material-dispensing member 50 is provided in the material box 20 and close to the top of the material box 20, and the bottom end of the material-dispensing member 50 interferes with the paddle 32 of the feeding member 30, that is, in the height direction, the material-dispensing member 50 and the feeding member 30 are completely distributed in the space of the material to be ground. Therefore, the material to be ground in the material box 20 and the grinding chamber can be fully stirred to avoid accumulation, thereby ensuring that the material to be ground enters the grinding chamber and is ground by the tool assembly 10; second, the power source of the material-dispensing member 50 comes from the driving assembly 40, so there is no need to provide an additional power source, that is, the existing grinding machine can be directly utilized. The power source of the grinding device achieves the technical effect of preventing the accumulation of the material to be ground without significantly increasing the cost and changing the existing structure of the grinding device; thirdly, since the movement of the material-dispensing member 50 is first driven by the driving component 40 to drive the feeding member 30 to rotate, and then the material-dispensing member 50 is driven to move by the dispensing blade 32 of the feeding member 30, the force generated when the material-dispensing member 50 moves is reduced. The magnitude of this force can ensure that the material to be ground will not accumulate, and at the same time will not cause safety hazards to the user; fourthly, when disassembling the material box 20, it is only necessary to remove the material-dispensing member 50 first to ensure that the material door 23 is smoothly closed, and the material to be ground during the disassembly process of the material box 20 is prevented from leaking out, and the operation is relatively simple.

[0070] Furthermore, in one embodiment of the present invention, the grinding device includes a blanking member 60, which forms a blanking channel 61. The material box 20 is detachably connected to the blanking member 60, and a sealing member 62 is provided between the blanking member 60 and the material box 20.

[0071] When the user needs to take out the material box 20, the material door 23 can be closed and the material box 20 can be removed. When the material box 20 is installed in the blanking member 60, the bottom of the material box 20 will extend into the blanking channel 61, and the sealing member 62 will seal the gap between the material box 20 and the blanking member 60, thereby preventing tea leaves and ground materials from entering the gap between the material box 20 and the blanking member 60 and overflowing, affecting the user experience.

[0072] In this embodiment, the paddle 32 is rod-shaped and has a fixed end connected to the rod body 31 and a free end opposite to the fixed end. The extension direction X3 of the paddle 32 can be the length direction of the paddle 32.

[0073] Furthermore, in one embodiment of the present invention, the extension direction X3 of the paddles 32 forms an angle with the rotation axis X1 of the feeder 30, and the fixed end of the paddles 32 is closer to the top of the rod 31 than the free end of the paddles 32. When the feeder 30 rotates, it drives the material to be ground within the drop channel 61. The paddles 32 of the feeder 30 all converge toward the bottom of the feeder 30, providing downward force to the material to be ground, ensuring a smooth drop.

[0074] In this embodiment, the feeder 30 includes at least two rows of blades 32 along the rotation axis X1 of the feeder 30 , and the length of the blades 32 near the bottom end of the feeder 30 is greater than that of the other blades 32 .

[0075] The paddle 32 near the bottom end of the feeding piece 30 is near the grinding chamber. Setting it to a longer length can reduce the distance between it and the wall of the grinding chamber, preventing the material to be ground from overflowing from the grinding chamber, thereby improving the grinding efficiency.

[0076] In this embodiment, each row of the paddles 32 may include two symmetrically arranged paddles 32. At least two rows of the paddles 32 may be staggered along the circumference of the rod 31 of the material paddle member 50. Figure 8 FIG. 3 is a top view of the feeding member 30 , in which a plurality of blades 32 are evenly spaced in the circumferential direction.

[0077] In the specific embodiment provided by the utility model, the feeder 30 includes three rows of paddles 32, each row of paddles 32 comprising two symmetrically arranged paddles 32. The two rows of paddles 32 near the top can interfere with the feeder 50. That is, during the rotation of the feeder 30, four paddles 32 sequentially interfere with the feeder 50 for each revolution of the feeder 30. This ensures a consistent frequency of movement of the feeder 50, achieving a superior anti-accumulation effect.

[0078] In summary, the simultaneous provision of the feed member 30 and the material dispensing member 50 in this embodiment prevents accumulation of material to be ground in the material box 20, ensuring stable grinding of the material within the grinding chamber and high grinding efficiency. Furthermore, the material dispensing member 50 can be directly installed using existing grid components, resulting in low overall cost and greater safety, without posing a safety hazard to the user.
