[0002] At present, there are some coffee bean grinding equipment on the market that can grind coffee beans into coffee powder. When grinding beans, the equipment grinds the coffee beans into powder through two grinding knives that rotate relative to each other and have a grinding gap between them. However, in the prior art, the grinding gap between the two grinding knives on some grinding equipment cannot be adjusted, and there is a disadvantage that the coarseness of the coffee powder is fixed. Some grinding equipment is equipped with a grinding coarseness adjustment device, but the coffee pot of this adjustment device is fixedly set on the frame and cannot be disassembled, which makes cleaning very inconvenient. Utility Model Content

[0003] The utility model provides a grinding coarseness adjustment device and a coffee bean grinding device, aiming to solve the problem that a coffee pot in a grinding coarseness adjustment device on a coffee bean grinding device in the prior art is fixedly connected to a frame and cannot be disassembled, resulting in very inconvenient cleaning.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] In a first aspect, the utility model provides a grinding coarseness adjustment device, comprising:

[0007] A grinding assembly is arranged on the frame, comprising a rotating grinding knife and a lifting grinding knife sleeved on the outer side of the rotating grinding knife, a grinding gap is arranged between the rotating grinding knife and the lifting grinding knife, and the grinding gap is adjusted by driving the lifting grinding knife to move up and down; and

[0008] The adjusting device comprises a coffee pot assembly arranged on the frame, a transmission assembly, and a lifting knife sharpening mounting seat arranged on the frame for sliding up and down; the lifting knife sharpening is mounted on the lifting knife sharpening mounting seat; the coffee pot assembly is detachably connected to the frame;

[0009] When the coffee pot assembly is rotated, the coffee pot assembly drives the lifting knife sharpener mounting seat and the lifting knife sharpener to move up and down along the frame through the transmission assembly.

[0010] A further solution: the transmission assembly includes a threaded seat rotatably arranged on the frame and sleeved on the outer side of the lifting and grinding tool mounting seat, and the threaded seat is threadedly connected to the lifting and grinding tool mounting seat.

[0011] A further solution: the transmission assembly also includes a rotating seat rotatably arranged on the frame and synchronously rotatably connected to the threaded seat, and the coffee can assembly includes a driving seat synchronously rotatably connected to the rotating seat and a coffee can fixedly connected to the driving seat.

[0012] Based on the above technical solution: when the coffee can is rotated, the coffee can synchronously drives the driving seat to rotate, the driving seat drives the rotating seat to rotate, and the rotating seat drives the threaded seat to rotate. Since the threaded seat is threadedly connected to the lifting sharpener mounting seat, the threaded seat drives the lifting sharpener mounting seat to move up and down along the frame by rotating. The above transmission setting is more optimized, which is convenient for the design of disassembly of the coffee can assembly and the frame.

[0013] A further solution: the frame is provided with a coffee can mounting groove, an annular step is provided on the inner side wall surrounding the coffee can mounting groove, and the drive seat, the transmission assembly and the lifting sharpening mounting seat are all located at the lower side of the annular step;

[0014] The annular step is provided with a first yielding groove opening upward, the rotating seat is provided with a second yielding groove opening upward, and the driving seat is provided with a protrusion; the driving seat drives the rotating seat to rotate by being clamped in the second yielding groove by the protrusion;

[0015] When installing or disassembling the coffee can assembly, the protrusion, the second make way groove and the first make way groove are arranged in a line above and below; when the protrusion and the second make way groove are rotated to a position avoiding the first make way groove, the protrusion and the rotating seat are limited at the lower side of the annular step.

[0016] Based on the above technical solution: the above arrangement enables that when the coffee can assembly is rotated so that the protrusion, the second give way groove and the first give way groove are in a straight line, the protrusion can be disengaged upward from the first give way groove and the second give way groove; when the protrusion and the second give way groove are rotated to a position avoiding the first give way groove, the driving seat is limited to the lower side of the annular step and cannot be disengaged upward, so that the coffee can assembly cannot be disassembled; the above arrangement makes it more convenient to install and disassemble the coffee can assembly.

[0017] A further solution: a discharge port is provided on the lower side of the coffee can, and the coffee can assembly further comprises a baffle located on the lower side of the coffee can and used to block the discharge port, the baffle comprising a blocked state and an open state relative to the discharge port, and the baffle can be switched between the blocked state and the open state by rotating the coffee can relative to the baffle.

[0018] Based on the above technical solution: the baffle is used to block the discharge port on the lower side of the coffee can. By rotating the coffee can relative to the baffle, the baffle can be switched between the blocked state and the open state, which is convenient for user operation. In the open state, the discharge port is open and connected to the grinding gap of the grinding assembly, and the coffee beans in the coffee can can fall into the grinding gap through the discharge port; in the blocked state, the discharge port is closed, and the coffee beans in the coffee can can no longer fall from the discharge port, so that when the user disassembles the coffee can assembly, the coffee beans in the coffee can can be prevented from falling to other locations.

[0019] A further solution: the discharge port includes two fan-shaped discharge ports which are arranged on opposite sides of the bottom of the coffee can and are cocentrically arranged; the baffle is provided with two fan-shaped holes and two fan-shaped sealing portions, and the two fan-shaped holes and the two fan-shaped sealing portions are staggered cocentrically arranged; when the baffle is in an open state, the two fan-shaped holes and the two fan-shaped discharge ports overlap up and down; when the baffle is in a blocked state, the two fan-shaped sealing portions and the two fan-shaped discharge ports overlap up and down.

[0020] Based on the above technical solution: the arrangement of the fan-shaped discharge port, the fan-shaped hole and the fan-shaped blocking portion makes it easy for the user to switch the baffle to an open state or a blocked state by rotating the coffee can relative to the baffle.

[0021] A further solution is that a driving part is provided on the lower side of the coffee can, and a supporting part is provided on the circumference of the baffle. When the coffee can is rotated until the driving part abuts against the supporting part, the coffee can drives the baffle to rotate synchronously.

[0022] A further solution: the abutting portion comprises a first abutting portion and a second abutting portion respectively located on opposite sides of the baffle, and a fan-shaped gap is formed between the first abutting portion and the second abutting portion; the driving portion comprises a first driving portion and a second driving portion;

[0023] When the coffee can is rotated forward until the first driving part abuts against the first abutting part and the second driving part abuts against the second abutting part, the coffee can drives the baffle to rotate synchronously and the baffle is in an open state; when the coffee can is rotated reversely until the first driving part abuts against the second abutting part and the second driving part abuts against the first abutting part, the coffee can drives the baffle to rotate synchronously and the baffle is in a blocked state.

[0024] Based on the above technical solution: by providing two driving parts and two abutting parts, and providing a fan-shaped gap between the two abutting parts, it is convenient to switch the baffle between the blocked state and the open state by rotating the coffee can; when the coffee can is rotated forward until the baffle is in the open state, the coffee can can be rotated synchronously with the baffle by continuing to rotate the coffee can forward, so that the discharge port is always open when adjusting the grinding gap; when the coffee can is rotated reversely until the baffle is in the blocked position, the coffee can can be driven to rotate synchronously by continuing to rotate the coffee can reversely, so that it is convenient to rotate to the installation or disassembly position, thereby disassembling the coffee can assembly when the discharge port is in the blocked state.

[0025] Further solution: the coffee can assembly further comprises an annular fixing seat, the fixing seat being clamped with the frame; a first stopper is provided on the inner side wall surrounding the fixing seat, and a second stopper is provided on the baffle;

[0026] When the coffee can is rotated forward until the second stop portion abuts against the first stop portion, the coffee can cannot continue to rotate forward; when the coffee can is rotated reversely until the second stop portion abuts against the first stop portion, the coffee can cannot continue to rotate reversely.

[0027] Based on the above technical solution: through the cooperation of the first stopper and the second stopper, there are two positions, namely the maximum and the minimum, when adjusting the grinding gap.

[0028] A further solution: when the coffee can is rotated forward until the second stop portion abuts against the first stop portion, the baffle is in an open state; when the coffee can is rotated reversely until the second stop portion abuts against the first stop portion, the baffle is in a blocked state.

[0029] Based on the above technical solution: when the coffee can is rotated in the reverse direction until it can no longer rotate, the baffle is in a blocked state and the discharge port is closed, which facilitates the disassembly of the coffee can assembly and prevents the coffee beans in the coffee can from falling from the discharge port.

[0030] A further solution: a rotating handle is provided in the coffee can.

[0031] Based on the above technical solution: turning the handle makes it convenient for the user to operate the rotating coffee can to adjust the grinding gap.

[0032] A further solution is that a sealing ring is provided between the threaded seat and the lifting knife sharpening mounting seat.

[0033] Based on the above technical solution: the sealing ring can prevent coffee powder from falling into the frame through the gap between the threaded seat and the lifting grinder mounting seat.

[0034] In a second aspect, the utility model provides a coffee bean grinding device, comprising a grinding coarseness adjustment device as described in any scheme in the first aspect.

[0035] The beneficial effects of the utility model are:

[0036] The utility model provides a coffee pot assembly for holding coffee beans, and the lifting grinder is installed on the lifting grinder mounting seat so as to move up and down synchronously with the lifting grinder mounting seat. When adjusting, the coffee pot assembly is rotated, and the coffee pot assembly drives the lifting grinder mounting seat to move up and down through the transmission assembly, so as to adjust the grinding gap between the lifting grinder and the rotating grinder, and the coarseness of the ground coffee powder is adjusted by adjusting the size of the grinding gap. By providing a detachable connection between the coffee pot assembly and the frame, when powder blockage occurs, the user can first remove the coffee pot assembly from the frame, and then clean the grinding gap, so as to facilitate the user's operation.

In a preferred embodiment, there are two first guide portions 11, which are respectively located on opposite sides of the circular groove, and there are two second guide portions 82, which slide together with the two first guide portions 11 respectively.

[0059] In some specific embodiments, Figure 1 , Figure 3 and Figure 4 As shown, the transmission assembly also includes a rotating seat 6 rotatably arranged on the frame 1 and synchronously rotatably connected with the threaded seat 7, and the coffee can 2 assembly includes a driving seat 3 synchronously rotatably connected with the rotating seat 6 and a coffee can 2 fixedly connected with the driving seat 3. As a specific embodiment of the synchronous rotatable connection between the rotating seat 6 and the threaded seat 7, the rotating seat 6 is sleeved on the outer side of the threaded seat 7, and a first clamping portion 62 is provided on the inner side wall of the rotating seat 6, and a second clamping portion 71 is provided on the outer side wall of the threaded seat 7. The first clamping portion 62 cooperates with the second clamping portion 71, so that the rotating seat 6 synchronously drives the threaded seat 7 to rotate when rotating. Specifically, the first clamping portion 62 is a plurality of clamping blocks surrounding the circumference of the rotating seat 6, and the second clamping portion 71 is a plurality of clamping grooves surrounding the circumference of the threaded seat 7, and the clamping blocks are clamped in the clamping grooves one by one.

[0060] Among them, Figure 5 As shown, in order to reduce the friction between the rotating seat 6 and the frame 1 during rotation, a plurality of arc-shaped protrusions 12 are provided on the circumference of the upper end of the side wall of the circular groove. When the lower end of the rotating seat 6 rotates relative to the arc-shaped protrusions 12, the contact area is smaller and the friction force is smaller.

[0061] In this embodiment, Figures 1 to 7 As shown, the frame 1 is provided with a coffee can 2 mounting groove, the coffee can 2 is mounted in the coffee can 2 mounting groove, an annular step 14 is provided on the inner side wall surrounding the coffee can 2 mounting groove, the drive seat 3, the transmission assembly and the lifting sharpening mounting seat 8 are all located on the lower side of the annular step 14; specifically, the coffee can 2 is located on the upper side of the drive seat 3, the drive seat 3 is located on the upper side of the rotating seat 6, and the rotating seat 6 is located on the upper side of the threaded seat 7.

[0062] The annular step 14 is provided with a first give way groove 141 with an upward opening, the rotating seat 6 is provided with a second give way groove 61 with an upward opening, and the driving seat 3 is provided with a protrusion 31, and specifically, the protrusion 31 is provided to protrude outward from a certain point on the circumference of the driving seat 3; the driving seat 3 drives the rotating seat 6 to rotate by the protrusion 31 being stuck in the second give way groove 61; that is, when the protrusion 31 is stuck in the second give way groove 61, the driving seat 3 and the rotating seat 6 are synchronously rotated and connected.

[0063] When installing or disassembling the coffee can 2 assembly, the protrusion 31, the second make way groove 61 and the first make way groove 141 are arranged in a line up and down. At this time, the protrusion 31 can be directly disengaged from the first make way groove 141 and the second make way groove 61 upwards, or the protrusion 31 can be passed downward through the first make way groove 141 and then clamped in the second make way groove 61. After the installation is completed, the protrusion 31 and the rotating seat 6 are located at the lower side of the annular step 14; when the coffee can 2 is rotated to make the protrusion 31 and the second make way groove 61 rotate to a position avoiding the first make way groove 141, the protrusion 31 and the rotating seat 6 are limited to the lower side of the annular step 14. In this state, the user cannot lift the coffee can 2 assembly upwards. When the coffee can 2 assembly needs to be disassembled, the protrusion 31 and the second make way groove 61 need to be rotated to the first make way groove 141.

[0064] In some specific embodiments, the number of the protrusion 31, the second clearance groove 61 and the first clearance groove 141 is preferably two, and they correspond to each other one by one. The two protrusions 31 are respectively located on the opposite sides of the driving seat 3 in the circumferential direction. This arrangement makes the coffee can 2 assembly more stable during rotation.

[0065] In this embodiment, Figure 8 and Fig. 9As shown, the lower side of the coffee can 2 is provided with a discharge port 22. In order to prevent coffee beans from falling from the discharge port 22 when the coffee can 2 is disassembled, the coffee can 2 assembly further includes a baffle 4 located at the lower side of the coffee can 2 and used to block the discharge port 22. The baffle 4 includes a blocking state and an open state relative to the discharge port 22. The baffle 4 can be switched between the blocking state and the open state by rotating the coffee can 2 relative to the baffle 4. Specifically, when the baffle 4 is in the open state, the discharge port 22 is opened and connected to the grinding gap of the grinding assembly, and the coffee beans in the coffee can 2 can fall into the grinding gap through the discharge port 22; when in the blocked state, the discharge port 22 is closed, and the coffee beans in the coffee can 2 can no longer fall from the discharge port 22.

[0066] In some specific embodiments, Figure 2 , Figure 8 and Fig. 9 As shown, the discharge port 22 includes two fan-shaped discharge ports 22 arranged on opposite sides of the bottom of the coffee can 2 and arranged concentrically; the baffle 4 is provided with two fan-shaped holes 42 and two fan-shaped blocking portions 41, and the two fan-shaped holes 42 and the two fan-shaped blocking portions 41 are arranged concentrically and staggered; when the baffle 4 is in an open state, the two fan-shaped holes 42 and the two fan-shaped discharge ports 22 overlap up and down; when the baffle 4 is in a blocked state, the two fan-shaped blocking portions 41 overlap up and down with the two fan-shaped discharge ports 22. Specifically, for example, when the baffle 4 switches from a blocked state to an open state, the overlap area of ​​the two fan-shaped blocking portions 41 and the two fan-shaped discharge ports 22 gradually decreases, and at the same time, the overlap area of ​​the two fan-shaped holes 42 and the two fan-shaped discharge ports 22 gradually increases.

[0067] In some specific embodiments, a driving portion is provided on the lower side of the coffee can 2, and a supporting portion is provided on the circumference of the baffle 4. When the coffee can 2 is rotated until the driving portion abuts against the supporting portion, the coffee can 2 drives the baffle 4 to rotate synchronously.

[0068] Specifically, the abutment portion includes a first abutment portion 43 and a second abutment portion 44 respectively located on opposite sides of the baffle 4, and there is a fan-shaped gap between the first abutment portion 43 and the second abutment portion 44. The first abutment portion 43 and the second abutment portion 44 can both be set to be arc-shaped; the driving portion includes a first driving portion 24 and a second driving portion 25.

[0069] In some preferred embodiments, the baffle 4 is located between the coffee can 2 and the driving seat 3, and the first driving part 24 and the second driving part 25 can both be columns, and the two columns are fixedly connected to the driving seat 3 by two screws 10 respectively.

[0070] When adjusting the grinding gap, when the coffee can 2 is rotated forward until the first driving part 24 abuts against the first abutting part 43 and the second driving part 25 abuts against the second abutting part 44, the coffee can 2 drives the baffle 4 to rotate synchronously and the baffle 4 is in an open state; when the coffee can 2 is rotated reversely until the first driving part 24 abuts against the second abutting part 44 and the second driving part 25 abuts against the first abutting part 43, the coffee can 2 drives the baffle 4 to rotate synchronously and the baffle 4 is in a blocked state.

[0071] Among them, in order to remind the user that the coffee can 2 cannot be rotated further when the grinding gap is adjusted to the maximum or minimum position, the coffee can 2 assembly also includes an annular fixing seat 5, and the fixing seat 5 is snap-connected with the frame 1, that is, the fixing seat 5 cannot rotate relative to the frame 1; a first stop portion 52 is provided on the inner side wall surrounding the fixing seat 5, and a second stop portion 45 is provided on the baffle 4; the first stop portion 52 is preferably arranged on the first abutment portion 43.

[0072] When the coffee can 2 is rotated forward until the second stop portion 45 abuts against the first stop portion 52, the coffee can 2 cannot continue to rotate forward; when the coffee can 2 is rotated reversely until the second stop portion 45 abuts against the first stop portion 52, the coffee can 2 cannot continue to rotate reversely.

[0073] In some specific embodiments, forward rotation causes the lifting knife sharpener mounting seat 8 to rise, and reverse rotation causes the lifting knife sharpener mounting seat 8 to fall. When the coffee can 2 is rotated forward until the second stop portion 45 abuts against the first stop portion 52, the baffle 4 is in an open state; when the coffee can 2 is rotated reversely until the second stop portion 45 abuts against the first stop portion 52, the baffle 4 is in a blocked state.

[0074] Among them, in some specific embodiments, it is preferred that when the coffee can 2 is rotated in the reverse direction until the second stop portion 45 abuts against the first stop portion 52, the protrusion 31, the first make way groove 141 and the second make way groove 61 are in a straight line, and the baffle 4 is in a blocked state, which is convenient for disassembly of the coffee can 2 assembly.

[0075] In some specific embodiments, Figure 2 As shown, a limit block 51 is provided on the fixing seat 5, and a limit slot is provided on the annular step 14. The limit block 51 is engaged in the limit slot so that the fixing seat 5 cannot rotate relative to the frame 1. A preferred solution is that the limit slot is the first clearance slot 141. When the coffee can 2 assembly is installed, the limit block 51 is engaged in the first clearance slot 141 from top to bottom.

[0076] In some specific embodiments, Figure 8 and Fig. 9 As shown, the coffee can 2 is provided with a rotating handle 21, which is preferably integrally formed with the coffee can 2, and the rotating handle 21 is coaxial with the coffee can 2. In order to facilitate user operation, an anti-slip head 211 is provided at the upper end of the rotating handle 21, and anti-slip patterns are provided on the circumference of the anti-slip head 211 to improve the hand feel. A cover 23 is provided on the upper side of the coffee can 2, and when the rotating handle 21 needs to be rotated, the cover 23 is opened first.

[0077] Embodiment 2:

[0078] This embodiment provides a coffee bean grinding device, including a grinding coarseness adjustment device as described in any scheme in Embodiment 1.

[0079] Working principle description:

[0080] After the coffee can 2 assembly is installed in the coffee can slot 13, the protrusion 31 on the drive seat 3 is clamped in the second clearance groove 61 on the rotating seat 6, and the baffle 4 is in a blocked state. When the coffee can 2 is rotated forward, the coffee can 2 drives the rotating seat 6 to rotate through the drive seat 3, and then the rotating seat 6 drives the threaded seat 7 to rotate, so that the lifting and lowering grinder mounting seat 8 moves upward, and the grinding gap increases. In this process, the baffle 4 gradually switches from the blocked state to the open state. When the coffee can 2 is rotated in the reverse direction so that the protrusion 31, the second clearance groove 61 and the first clearance groove 141 are in the upper and lower lines, the user can remove the coffee can 2 assembly upward from the frame 1.

[0081] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily.
