[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-6 , the utility model embodiment includes:

[0028] A semi-automatic grinding degree adjustment system with manual adjustment and digital display, wherein the grinding degree adjustment system 2 is connected to an idler wheel 101 in a coffee machine grinder 1, so as to adjust the grinding coarseness (tool clearance) by adjusting the height of the idler wheel 101. The structure thereof includes: a manual bean grinding adjustment gear 3, a bean grinding adjustment seat 4, a bean grinding paddle 5, a bean grinding adjustment cover 6, a shaft retaining spring 7, a gear position detection device 8, a screw 9, a digital display screen 10, a coffee machine 11, and a coffee machine main control board 12.

[0029] The bean grinding adjustment cover 6 is fixedly engaged with the slot at the bottom of the bean grinding adjustment seat 4 through a buckle to form an adjustment seat body, and the adjustment seat body is movably connected to the coffee machine grinder 1.

[0030] Further preferably, a guide rib 61 is provided on the adjustment base (or the bean grinding adjustment cover 6), and a guide groove 62 movably connected to the guide rib is provided on the side wall of the coffee machine grinder 1, so that the adjustment base and the coffee machine grinder 1 are matched and fixed, wherein a plurality of guide grooves 62 may be provided on the coffee machine grinder 1, and the corresponding slot position may be selected during installation according to environmental restrictions and usage requirements.

[0031] The gear part 31 in the manual bean grinding adjustment gear part 3 can be rotatably arranged in the bean grinding adjustment seat 4, and meshes with the gear ring 102 on the outer periphery of the idler wheel 101 in the coffee machine grinder 1 to drive the idler wheel 101 to move. The top surface of the gear part 31 is connected with an adjustment rod 32, and the gear part 31 can be driven to rotate by rotating the adjustment rod 32. The connecting shaft 33 connected to the bottom surface of the gear part 31 passes through the bean grinding adjustment seat 4 and the bean grinding adjustment cover 6 in sequence and extends outward. The shaft arranged under the bean grinding adjustment cover 6 is clamped in the clamping groove at the lower part of the connecting shaft 33 with a clamping spring 7 to prevent the manual bean grinding adjustment gear part 3 from being separated from the bean grinding adjustment seat 4 and the bean grinding adjustment cover 6.

[0032] A plurality of locking convex teeth are radially distributed on the outer peripheral wall of the connecting shaft 33 near the gear part 31, or a locking gear shaft 34 with a plurality of locking convex teeth is arranged between the gear part 31 and the connecting shaft 33. The bean grinder 5 is fixedly connected with the bottom surface of the bean grinder adjustment seat 4 by interference fit, and the locking hooks 51 at both ends of the bean grinder 5, which have a certain elasticity and reset function, are movably connected with the locking convex teeth on the locking gear shaft 34 to realize the unlocking / locking function of the gear position (the position of the manual bean grinder adjustment gear part 3). When the manual bean grinder adjustment gear part 3 rotates, the locking convex teeth push the locking hook 51, and the locking hook produces a certain deformation due to its own elastic force, so that the locking hook is separated from the locking convex teeth. When the manual bean grinder adjustment gear part 3 rotates a certain angle or stops after a gear position, the locking hook 51 resets and hooks the locking convex teeth to realize the self-locking of the gear position.

[0033] The tooth spacing of the locking protruding teeth can be set according to actual use requirements. In this embodiment, the manual adjustment gear member 3 for grinding beans is rotated 21.5 degrees as the first gear.

[0034] Among them, the coffee machine grinder 1 can directly adopt the existing grinder, and its structure is generally as follows: a grinding driving wheel is arranged in the coffee machine grinder 1, and a driving mechanism for driving the grinding driving wheel to rotate in the grinder is connected to the grinding driving wheel, and an idler wheel 101 is threadedly connected to the coffee grinder above the grinding driving wheel, and the manual adjustment gear part 3 for grinding beans is meshed with the ring gear 102 on the outer periphery of the idler wheel. When the adjustment rod 32 of the manual adjustment gear part 3 for grinding beans is rotated clockwise, the adjustment rod drives the idler wheel 101 on the grinding system 1 to rotate counterclockwise through the gear part 31 to adjust the distance between the grinding driving wheel and the idler wheel 101, thereby adjusting the coarseness of the grinding.

[0035] Further preferably, the gear portion 31 , the adjusting rod 32 , the connecting shaft 33 and the locking protrusion 34 are an integrated structure.

[0036] Further preferably, the grinding bean adjustment seat 4 is provided with a through hole 43 allowing the connecting shaft 33 to pass through, and the outer periphery of the upper opening of the through hole is connected to a movable groove 42, and a limit block 41 is provided in the movable groove. A stopper is provided on the bottom surface or below the gear portion 31, and the stopper is movably connected to the limiter to perform foolproof protection, so as to cooperate with limiting the rotation range of the manual grinding bean adjustment gear member, so that the adjustment range of the manual grinding bean adjustment gear member is within 280°.

[0037] The gear position detection device 8 is placed in the slot position on the bottom surface of the grinding bean adjustment cover 6, and is rotated and fastened to the bottom of the grinding bean adjustment cover 6 using two ST3×10-T10 screws 9. The gear position detection device 8 is movably connected to the end of the connecting shaft 33 to detect the rotation angle or number of rotations of the connecting shaft 33, and the detection result is sent to the coffee machine main control board 12 in real time for display.

[0038] The gear position detection device 8 can adopt a grating feedback device or a position feedback device.

[0039] Alternatively, the gear detection device 8 includes a 360° potentiometer 81 (impedance ranges from a default 0 impedance point to a clockwise 1 impedance point) and an electrical control board 82 electrically connected to the potentiometer. The bottom of the connecting shaft 33 is inserted into the center hole of the movable part of the potentiometer. When the connecting shaft 33 rotates, the connecting shaft 33 will rotate with the movable part of the potentiometer, thereby causing the resistance value of the potentiometer to change. That is, each time the connecting shaft 33 completes a rotation (21.5°), the movable part of the potentiometer also rotates synchronously once, and the resistance value of the potentiometer changes correspondingly. One rotation corresponds to one resistance value (the gear corresponding to each organization can be preset in the system). The current resistance value of the potentiometer is read by the electrical control board to determine the current adjustment angle / gear and send it to the coffee machine main control board 12.

[0040] exist Figure 6In the embodiment, the three connectors of the potentiometer R1 are electrically connected to the pins 1, 2, and 3 of the electrical control board P1, respectively, so that the electrical control board can obtain the resistance value of the potentiometer in real time.

[0041] The digital display screen 10 and the coffee machine main control board 12 are arranged on the coffee machine 11. The coffee machine main control board 12 is respectively connected to the gear detection device 8 and the digital display screen 10 for communication. When the manual adjustment gear part 3 for grinding beans rotates to adjust the gear, the gear detection device 8 detects the movement of the connecting shaft 33 in real time and transmits the corresponding resistance signal to the coffee machine main control board 12. After being processed by the CPU on the coffee machine main control board, the gear light related data is displayed in the corresponding screen area on the digital display screen 10 to feedback the data information in real time.

[0042] The controllable adjustment range of the grinding degree adjustment system 2 is within 280°, which is divided into 13 controllable adjustment gears, each gear is 21.5°, and each time it rotates 1 gear, the gear number corresponding to the digital display screen will advance one gear number, from 1 gear until it rotates 13 times to the maximum gear.

[0043] When the manual adjustment gear for grinding beans is adjusted to the 1st gear, the idler wheel 101 in the corresponding grinding system 1 is at the starting position, and the grinding coarseness (the tool gap is the largest) is the coarsest; when the manual adjustment gear for grinding beans is adjusted to the 1st gear, the idler wheel 101 in the corresponding grinding system 1 is at the 2 / 13 position, and the grinding coarseness (the tool gap is 2 / 13 at most) is 2 / 13 coarse; and so on, until the 13th gear, the idler wheel 101 is at the maximum movement position, and the grinding coarseness (the tool gap is the smallest) is the finest.

[0044] The beneficial effects of the semi-automatic grinding degree adjustment system capable of manual adjustment and digital display are:

[0045] 1. It can effectively improve the accuracy of coffee powder grinding and the stability of the ground products, timely improve and optimize the coarseness of coffee powder, avoid the blockage of the brewing system caused by too fine coffee powder and the inability to extract coffee oil caused by too coarse coffee powder, and improve customer experience and satisfaction;

[0046] 2. It not only has the stability of manual grinding adjustment, but also can reduce costs, making the product more cost-effective. It can also detect and display the grinding gear data in real time during operation, improving customer experience and satisfaction;

[0047] 3. There is a default starting position during assembly, which is convenient for disassembly and assembly. It has a simple structure and good versatility, and can meet different practical needs.

[0048] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
