[0002] In order to adjust the grinding coefficient, the existing coffee machine mainly adjusts the distance between the first blade disc and the second blade disc. When making the adjustment, the existing practice is to form a threaded structure on one of the blade discs. When installing the blade disc, it is first assembled to the blade disc seat through threads. After the installation is in place, the rotation of the blade disc is limited by the upper limit structure on the blade seat, and then the up and down adjustment is achieved by thread rotation. In such a structure, the disassembly and adjustment of the blade disc are all achieved by the threaded structure. In this way, the threaded structure is easily worn due to long-term disassembly and assembly, which affects the adjustment accuracy of the blade disc.

Therefore, they cannot be understood as limiting the present invention.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] Embodiment 1,

[0039] See also Figure 1-Figure 11 The present invention discloses a cutter disc structure, including a cutter disc assembly, an adjustment assembly and a stopper. The cutter disc assembly includes a cutter disc seat 50, a first cutter disc 41 and a second cutter disc 42. A first connecting portion is provided on the first cutter disc 41. The adjustment assembly includes a first adjustment ring 10 and a second adjustment ring 20. The first adjustment ring 10 is connected to the cutter disc seat 50. A first guide portion 12 is provided on the first adjustment ring 10. The second adjustment ring 20 is rotatably matched with the first adjustment ring 10. A second guide portion 23 and a second connecting portion are provided on the second adjustment ring 20. The second connecting portion is detachably connected with the first connecting portion so that the second adjustment ring 20 is detachably connected with the first cutter disc 41. The second guide portion 23 is movably matched with the first guide portion 12 to guide the second adjustment ring 20 to move along its own axial direction to adjust the distance between the first cutter disc 41 and the second cutter disc 42.

[0040] The above-mentioned anti-rotation member is installed on the cutter disc seat 50, and specifically, a anti-rotation portion is provided on the second adjustment ring 20. When performing the adjustment action, the anti-rotation member can abut against the anti-rotation portion to limit the rotation of the second adjustment ring 20, and the anti-rotation member and the anti-rotation portion are slidably matched in the axial direction.

[0041] It should be noted that the blade disc structure in this embodiment can be used in a coffee machine or a bean grinder to adjust the position of the blade disc on the coffee machine or the bean grinder. The blade disc seat 50 is used as an assembly basis for the first blade disc 41, the second blade disc 42, the first adjustment ring 10, and the second adjustment ring 20. When used in a coffee machine, the blade disc seat 50 can be the base of the coffee machine; when used in a bean grinder, the blade disc seat 50 can be the base of the bean grinder; of course, the blade disc seat 50 can also be set separately with the base as the assembly basis, and there is no specific limitation.

[0042] On the basis of the above structure, when the cutter disc structure of the present invention is used, its first adjustment ring 10 is installed to the cutter disc seat 50, and then the second adjustment ring 20 is rotatably assembled with the first adjustment ring 10. After the first guide portion 12 on the first adjustment ring 10 and the second guide portion 23 of the second adjustment ring 20 are flexibly matched, the first connecting portion of the first cutter disc 41 is connected to the second connecting portion of the second adjustment ring 20, that is, the first cutter disc 41 and the second adjustment ring 20 are directly assembled in place with the first connecting portion and the second connecting portion. Thereafter, by rotating the first adjustment ring 10 or the second adjustment ring 20, during the relative rotation of the two, the axial displacement of the second adjustment ring 20 is realized by the flexibly matched first guide portion 12 and second guide portion 23, so that the position adjustment of the first cutter disc 41 can be realized. The above-mentioned second cutter disc 42 is spaced apart from the first cutter disc 41. By adjusting the position of the first cutter disc 41, the spacing between the first cutter disc 41 and the second cutter disc 42 can be adjusted, thereby adjusting the grinding gap.

[0043] In this embodiment, the first adjustment ring 10 and the second adjustment ring 20 are assembled on the cutter disc seat 50, so the assembly accuracy and relative position between the two will not be affected by the assembly of the first cutter disc 41. When the first cutter disc 41 is installed, the first connection part of the first cutter disc 41 is connected to the second connection part of the second adjustment ring 20. During the assembly process, the second adjustment ring 20 will not rotate due to the installation of the first cutter disc 41. Therefore, after the first cutter disc 41 is assembled in place, the relative position of the first adjustment ring 10 and the second adjustment ring 20 is the starting position of the preset position. When the first cutter disc 41 is taken out, the first connection part of the first cutter disc 41 and the second connection part of the second adjustment ring 20 can be detached. Even if it is installed here, the relative position of the second adjustment ring 20 and the first adjustment ring 10 does not need to be adjusted to the starting position, which is convenient for operation.

[0044] In addition, since the position adjustment of the first cutter disc 41 is achieved by the rotation of the second adjustment ring 20, the rotation of the first cutter disc 41 is generally not required when the axial position is adjusted. Therefore, a stop structure is required to limit the rotation of the second adjustment ring 20. When the second adjustment ring 20 rotates, the stop member acts on the stop portion to prevent the second adjustment ring 20 from driving the first cutter disc 41 to rotate during rotation, so that the first cutter disc 41 only moves in the axial position, thereby achieving the adjustment of the grinding distance between the first cutter disc 41 and the second cutter disc 42.

[0045] The above-mentioned anti-rotation member can be assembled on the cutter disc seat 50 after the first adjustment ring 10 and the second adjustment ring 20 are assembled, and after being assembled on the cutter disc seat 50, it abuts against the anti-rotation part of the second adjustment ring 20 to limit the rotational movement of the second adjustment ring 20 while allowing the second adjustment ring 20 to move axially. In this way, the anti-rotation member can be detached separately, and there is no need to set a anti-rotation component that cooperates with the second adjustment ring 20 on the first adjustment ring 10, so that it will not affect the internal structure. The anti-rotation operation of the anti-rotation member is performed separately on the cutter disc seat 50, which will not be restricted by the first adjustment ring 10, the second adjustment ring 20 or the first cutter disc 41, the second cutter disc 42 and other structures, and the operation is convenient.

[0046] Of course, the above-mentioned first guide portion 12 and the second guide portion 23 can be a threaded structure, specifically, a first thread segment is set on the first adjustment circle 10, and a second thread segment threadedly matched with it is correspondingly set on the second adjustment circle 20. When adjusting the position of the cutter disc, by rotating the first adjustment circle 10 or the second adjustment circle 20, in this embodiment, by rotating the first adjustment circle 10, when the first adjustment circle 10 rotates, the first thread segment and the second thread segment threadably cooperate to realize the axial position adjustment of the second adjustment circle 20, thereby adjusting the distance between the first cutter disc 41 and the second cutter disc 42.

[0047] In addition, the first guide portion 12 may also be a guide column, and the second guide portion 23 may be a spiral groove or an arc groove, etc. When the first adjustment ring 10 rotates, the guide column of the first adjustment ring 10 slides in the spiral groove or the arc groove structure, and may also guide the second adjustment ring 20 up and down to realize the movement of the first cutter disc 41, thereby adjusting the distance between the first cutter disc 41 and the second cutter disc 42. The specific structures of the first guide portion 12 of the first adjustment ring 10 and the second guide portion 23 of the second adjustment ring 20 are not limited in this application.

[0048] Furthermore, the above-mentioned anti-rotation member includes an anti-rotation block 31 and an elastic component. The above-mentioned elastic component can be connected to the cutter disc seat 50. After the anti-rotation block 31 is assembled to the cutter disc seat 50, the elastic component is connected to the cutter disc seat 50 and presses on the anti-rotation block 31. The elastic component can provide an elastic stress. Under the action of the elastic stress, the anti-rotation block 31 can be close to the anti-rotation part to achieve anti-rotation. In this way, when the anti-rotation member is assembled, the anti-rotation member presses the anti-rotation block 31 through the elastic stress provided by the elastic component. The force acting on the anti-rotation block 31 is an elastic force. Therefore, when the second adjustment ring 20 is driven by the first adjustment ring 10, it can have an axial movement tendency and will not be stuck under the action of the hard force.

[0049] The specific anti-rotation component can be assembled based on the base of the coffee machine or the grinder. The anti-rotation block 31 is connected to the cutter disc seat 50 through an elastic component. The cutter disc seat 50 is directly connected to the base of the coffee machine or the grinder, rather than being assembled to the first adjustment circle 10, the second adjustment circle 20 or the cutter disc structure. That is, the anti-rotation structure is additionally arranged on the base, which will not increase the assembly space between the first adjustment circle 10 and the second adjustment circle 20, thereby reducing internal interference.

[0050] Specifically, a stop tooth 311 is provided on the stop block 31, and the stop portion corresponding to the stop groove 21 provided on the second adjustment ring 20 is the stop block 31. The stop block 31 is close to the stop groove 21 under the action of the elastic component, and the stop block 31 is engaged with the stop groove 21 of the second adjustment ring 20 with the stop tooth 311, and the stop groove 21 and the stop tooth 311 are used for restriction, so that the stop structure is more stable.

[0051] Furthermore, a plurality of anti-rotation grooves 21 are provided on the circumference of the second adjustment ring 20; at least two anti-rotation teeth 311 are provided on the anti-rotation member; and the anti-rotation teeth 311 are inserted into the anti-rotation grooves 21. A plurality of anti-rotation grooves 21 are provided on the circumference, so during assembly, the anti-rotation teeth 311 of the anti-rotation member can be inserted into one of them, and there is no need to assemble one by one, which reduces the difficulty of assembly.

[0052] Furthermore, the end surface of the stop block 31 away from the stop tooth 311 is provided with abutment groove 312, and the elastic component includes an elastic metal rod 32, and the elastic metal rod 32 includes an elastic protruding section 321 and an elastic connecting section 322, and both ends of the elastic protruding section 321 are connected with elastic connecting sections 322; the elastic protruding section 321 abuts against the abutment groove 312. Based on this structure, when assembling the stopper, the stopper is assembled to the machine base, and then the elastic connecting sections 322 at both ends of the elastic metal rod 32 are respectively connected to the machine base, so that the middle elastic protruding section 321 can extend into the abutment groove 312 of the stop block 31, and elastically press on the stop block 31, so that the stopper can be stably pressed in the stop groove 21 of the second adjustment ring 20.

[0053] In this embodiment, the anti-rotation block 31 is a rubber block. In other cases, the anti-rotation block 31 can also be a silicone block or a plastic block. The elastic stress applied by the rubber block and the elastic protrusion section 321 is more flexible. The rubber block assembly can also increase the friction of the anti-rotation groove 21 of the second adjustment ring 20 and prevent it from being separated.

[0054] Of course, the elastic component can also be selected as a spring in the prior art. Compared with the spring applying elastic force in its own length direction, it is easy to shake, resulting in unstable elastic force. The elastic connecting sections 322 on both sides of the present embodiment are respectively connected to the base, and are limited on both sides of the elastic protruding section 321 to prevent the elastic metal rod 32 from loosening.

[0055] Further, the first adjustment ring 10 is specifically arranged at the bottom end of the cutter seat 50, the second adjustment ring 20 is rotatably assembled with the first adjustment ring 10, the first adjustment ring 10 is provided with a connecting frame 11, the connecting frame 11 can protrude from the cutter seat 50, and the connecting frame 11 is provided with a connecting groove 111. Correspondingly, an adjustment ring 51 is provided at the top end of the cutter seat 50, and the adjustment ring 51 is rotatably assembled with the top end of the cutter seat 50. A connecting arm 511 is provided on the adjustment ring 51, and the connecting arm 511 is inserted into the connecting groove 111. The connecting arm 511 is used to drive the connecting frame 11 to rotate when the adjustment ring 51 rotates, so as to link the first adjustment ring 10.

[0056] On the basis of the above structure, when adjusting the distance between the cutter discs, the adjustment ring 51 at the top of the cutter disc seat 50 can be rotated. Since the adjustment ring 51 is connected to the connecting frame 11 of the first adjustment circle 10 through the connecting arm 511, the rotation of the adjustment ring 51 can drive the first adjustment circle 10 to rotate, and then drive the second adjustment circle 20 to move up and down.

[0057] It should be noted that, since the blade disc seat 50 is used for installing the blade disc structure, the blade disc is usually arranged inside the coffee machine or the bean grinder, and the top of the blade disc seat 50 is used to connect with the bean bin 60 structure for containing coffee beans, the adjustment ring 51 structure arranged on the top of the blade disc seat 50 can be exposed, that is, the adjustment structure used to adjust the blade disc gap is exposed, which is convenient for operation.

[0058] Furthermore, a stop opening 52 is provided on the cutter seat 50, and the stop portion on the second adjustment ring 20 can correspond to the position of the stop opening 52 of the cutter seat 50, so that the stop member can extend through the stop opening 52 to cooperate with the stop portion, that is, the stop member structure is assembled on the outside of the cutter seat 50, which is convenient for disassembly and assembly. In addition, the stop member is not arranged inside the cutter seat 50, so it will not interfere with other structures inside the cutter seat 50.

[0059] More specifically, the second adjustment ring 20 is rotatably disposed on the cutter head seat 50 and can slide axially; the second adjustment ring 20 is sleeved on the outside of the first adjustment ring 10 so that the second guide portion 23 and the first guide portion 12 can be flexibly matched. Based on this structure, the anti-rotation portion of the second adjustment ring 20 can be arranged on the outside of the second adjustment ring 20, and the second guide portion 23 is arranged inside the second adjustment ring 20. The second adjustment ring 20 is assembled on the outside of the first adjustment ring 10 to realize active assembly with the first guide portion 12 of the first adjustment ring 10.

[0060] Of course, if the first adjustment ring 10 is assembled on the outside of the second adjustment ring 20 during assembly, the first guide portion 12 of the first adjustment ring 10 can be set inside the first adjustment ring 10, and the second guide portion 23 of the second adjustment ring 20 can also be set outside the second adjustment ring 20. On this structural basis, the anti-rotation portion of the second adjustment ring 20 can also be set as an anti-rotation ring separately, which is distributed in the axial direction with the second guide portion 23 of the second adjustment ring 20, and the anti-rotation portion of the anti-rotation ring can also correspond to the anti-rotation port 52. In addition, if the anti-rotation port 52 is not set, the anti-rotation member can also be assembled inside the cutter head seat 50 through an elastic member.

[0061] Furthermore, since the adjusting ring 51 is used to drive the first adjusting ring 10 to rotate, the adjusting ring 51 is linked with the connecting arm 511 after being plugged in with the connecting frame 11. In order to prevent the two from rotating relative to each other after being plugged in, a limiting tooth 512 groove may be provided in the connecting groove 111, and a corresponding limiting tooth 512 is provided on the connecting arm 511. After the connecting arm 511 is assembled to the connecting groove 111, the limiting tooth 512 engages with the tooth groove. In this way, when the connecting arm 511 drives the connecting frame 11 to rotate, the limiting tooth 512 is limited in cooperation with the tooth groove, thereby reducing the relative rotation between the two, making the linkage structure between the adjusting ring 51 and the first adjusting ring 10 more stable.

[0062] Furthermore, a clamping block 414 may be provided on the first cutter disc 41, and a clamping groove 22 may be provided on the second adjustment ring 20. When the first cutter disc 41 is assembled to the second adjustment ring 20, the clamping block 414 on the first cutter disc 41 corresponds to the clamping groove 22 of the second adjustment ring 20, and the clamping block 414 is clamped into the clamping groove 22. Based on this structure, the clamping block 414 is the above-mentioned first connecting part, and the clamping groove 22 is the above-mentioned second connecting part.

[0063] The detachability of the first blade disc 41 and the second adjustment ring 20 is achieved by snapping together. During assembly, the first blade disc 41 is directly snapped into the snap-in slot 22 with the snap-in block 414. The snap-in slot 22 and the snap-in block 414 are snap-in limited, making assembly and disassembly convenient. After the snap-in block 414 is snap-into the snap-in slot 22, the snap-in block 414 can fill the slot after being inserted into the snap-in slot 22. After snap-in, the assembly structure is more stable.

[0064] Of course, a buckle can be directly provided on the first blade disc 41, and a buckle can be correspondingly provided on the second adjustment ring 20, so that the buckle and the buckle can be connected by a buckle. Alternatively, a spring pin can be provided on the first blade disc 41, and a spring pin hole can be provided on the second adjustment ring 20, and the spring pin can be inserted into the spring pin hole, so that the detachable assembly can also be achieved.

[0065] More specifically, a card interface is provided in the card slot 22, and the opening of the card interface is circumferentially arranged toward the second adjustment ring 20. When the first cutter disc 41 is assembled and the first cutter disc 41 is installed into the second adjustment ring 20, the card block 414 on the first cutter disc 41 is firstly staggered circumferentially with the card interface of the card slot 22, so that the first cutter disc 41 will not be blocked during the installation process. Thereafter, the card block 414 corresponds to the card interface of the card slot 22, and then the first cutter disc 41 is rotated, and the card block 414 of the first cutter disc 41 is connected to the card slot 22 via the card interface, thereby realizing the card connection between the first cutter disc 41 and the second adjustment ring 20.

[0066] It should be noted that compared with the card interface of the card slot 22 being arranged in the axial direction, although the first blade disc 41 can be directly installed from above, it is more convenient and simple for the card block 414 to be directly inserted into the card slot 22 from top to bottom. However, during use, the first blade disc 41 is also easy to detach from the second adjustment ring 20.

[0067] Therefore, in this embodiment, the clamping block 414 of the first blade disc 41 is rotated into the clamping groove 22 from the circumferential direction, and the top wall of the clamping groove 22 can be limited above the clamping block 414. After installation, the clamping block 414 is not easy to detach from the top, and the assembly structure is more stable.

[0068] More specifically, a limiting rib 221 may be provided in the snap-fitting groove 22, and a corresponding limiting groove 415 may be provided on the snap-fitting block 414. After the snap-fitting block 414 is rotated to the snap-fitting groove 22, the limiting rib 221 in the snap-fitting groove 22 may be snap-fitted into the limiting groove 415. In this way, the limiting rib 221 and the limiting groove 415 may be snap-fitted together to prevent the snap-fitting block 414 from being separated from the snap-fitting groove 22 in the circumferential direction. That is, after the snap-fitting block 414 is snapped into the snap-fitting groove 22, the limiting rib 221 and the limiting groove 415 are used to limit the snap-fitting block 414 in the circumferential direction, and the top wall of the snap-fitting groove 22 is used to limit the snap-fitting block 414 in the axial direction. This makes the assembly more stable.

[0069] Furthermore, if a limiting rib 221 and a limiting groove 415 structure are provided, the clamping block 414 is easily blocked by the limiting rib 221 during the clamping process. In order to prevent jamming, the limiting groove 415 is an arc groove, and the outer surface of the limiting rib 221 is an arc surface. During the clamping process, a smooth transition is made with the arc surface, and jamming is not likely to occur.

[0070] Of course, the above-mentioned limiting ribs 221 can also be implemented by an elastic rubber structure. The elastic rubber is easy to deform after being compressed, and can avoid being inserted or removed smoothly during the insertion process of the clamping block 414.

[0071] Furthermore, a first guiding bevel can be provided on the top wall of the snap-in slot 22, and a second guiding bevel can be provided at the top end of the snap-in block 414. When the snap-in block 414 is snapped into the snap-in slot 22, the first guiding bevel and the second guiding bevel slide together. Specifically, the first guiding bevel gradually tilts downward from one side of the card interface to the side away from the card interface. In this way, the second guiding bevel is gradually pressed during the snap-in process of the snap-in block 414, thereby pressing the snap-in block 414. In this way, the structure is more stable after snapping.

[0072] Furthermore, the first blade disc 41 is provided with a connection seat 411 and a metal blade seat 412, that is, the first blade disc 41 is composed of two parts, and the connection seat 411 can be made of hard plastic material, which is convenient for processing a clamping block 414 or other connection structure on the connection seat 411, and the cost is low, that is, based on this structure, the first connection part is set on the connection seat 411 as a connection basis. The metal blade seat 412 is provided with a plurality of blades 413, and the structure for setting a plurality of blade discs is made of metal material, which has better strength.

[0073] During assembly, the metal knife seat 412 and the connecting seat 411 can be assembled using structures such as screws. After the blades 413 of the metal knife seat 412 are worn, the metal knife seat 412 can be replaced.

[0074] Embodiment 2,

[0075] A coffee machine includes the blade disc structure of Example 1, and the blade disc structure is installed on the base of the coffee machine. The blade disc base 50 of the above-mentioned blade disc structure can be fixedly connected to the base of the coffee machine, and can also be formed by the base of the coffee machine. After the blade disc structure is assembled to the coffee machine, the second blade disc 42 can be set on the base of the coffee machine, driven by the driving structure 70 of the coffee machine to rotate, and cooperate with the first blade disc 41 to grind the coffee beans.

[0076] It should be noted that the working structure and principle of the specific blade disc structure for the coffee machine are the same as those in Example 1, and the other structures of the coffee machine are all existing technologies and will not be described in detail here.

[0077] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
