[0034] Please refer to Figures 1 to 7 Embodiment 1 of the present application provides a distance-measuring coffee bean grinder, which is used to grind coffee beans and specifically includes a control system, a cover body 1, a base 2, a movable blade disc mechanism, a fixed blade disc mechanism and a distance-measuring component.
[0035] The top of the base 2 is connected to the fixed blade mechanism, and the moving blade mechanism is sleeved in the middle of the fixed blade mechanism in the horizontal direction. The cover body 1 is arranged outside the moving blade mechanism and the fixed blade mechanism, and a moving blade 9 is arranged at one end of the moving blade mechanism, and a fixed blade 27 is arranged at one end of the fixed blade mechanism, and the grinding surfaces of the moving blade 9 and the fixed blade 27 are opposite to each other, and there is a grinding gap 3 between the moving blade 9 and the fixed blade 27. A feed port 7 connecting the fixed blade mechanism and the grinding gap 3 is provided at the top of the cover body 1, and a discharge port 8 connecting the grinding gap 3 is provided at the bottom. The distance measuring components are respectively arranged on the moving blade mechanism and the fixed blade mechanism, and the distance measuring components are electrically connected to the control system.
[0036] The coffee bean grinder can adjust the distance between the moving blade disc 9 and the fixed blade disc 27 according to the type of coffee beans being ground. First, start the distance adjustment component 28, and the distance adjustment component 28 drives the fixed blade disc 27 to move closer to or away from the moving blade disc 9 until the required distance. At this time, the distance measuring component detects the change in the distance between the fixed blade disc 27 and the moving blade disc 9, and records the distance so that it can be quickly adjusted to the same distance the next time it is used, thereby improving the adjustment accuracy between the grinding blade discs. When using the coffee bean grinder to grind coffee beans, pour the coffee beans from the feed port 7. After the coffee beans enter the grinding gap 3, start the moving blade disc mechanism to drive the moving blade disc 9 to rotate relative to the fixed blade disc 27 to grind the coffee beans. After the coffee beans are ground into powder, they fall into the holding container through the discharge port 8 at the bottom of the cover body 1.
[0037] Please refer to Figures 2 to 5 In a specific embodiment, the movable cutter disc mechanism further includes a driving assembly 10 and a leveling assembly 11. The movable cutter disc 9 is connected to the power output end of the driving assembly 10, and a feed thread 14 connecting the feed port 7, the fixed cutter disc mechanism, and the grinding gap 3 is provided around the power output end of the driving assembly 10, and the leveling assembly 11 is sleeved on the periphery of the driving assembly 10.
[0038] In a specific embodiment, the distance adjustment assembly 28 includes a first driving member 29, a first follower 30 and a second follower 31, the first follower 30 is rotatably connected to the outer peripheral wall of the leveling assembly 11, the first driving member 29 is threadedly connected to the first follower 30, and the first follower 30 is threadedly connected to the second follower 31, and the second follower 31 is fixedly connected to the fixed cutter disc 27. At the same time, the movable cutter disc 9 and the fixed cutter disc 27 are arranged parallel to each other, and the side of the movable cutter disc 9 with grinding teeth is opposite to the side of the fixed cutter disc 27 with grinding teeth.
[0039] Here, after the coffee bean grinder is assembled, in order to eliminate the parallelism error, it is necessary to first level the movable cutter disc 9 and the fixed cutter disc 27. Specifically, the leveling component 11 first drives the power output end of the driving component 10 to slide horizontally, thereby driving the movable cutter disc 9 to approach the fixed cutter disc 27 in the horizontal direction until the movable cutter disc 9 and the fixed cutter disc 27 are close to each other. At this time, the parallelism between the movable cutter disc 9 and the fixed cutter disc 27 is in a leveled state, that is, the movable cutter disc 9 and the fixed cutter disc 27 are parallel to each other in the vertical direction.
[0040] When the user adjusts the distance between the moving blade disc 9 and the fixed blade disc 27, the first driving member 29 is first started, the first driving member 29 is threadedly connected to the first follower 30 to drive the first follower 30 to rotate, the first follower 30 is threadedly connected to the second follower 31 to drive the second follower 31 to slide in the horizontal direction, and then drive the fixed blade disc 27 to approach or move away from the moving blade disc 9 in the horizontal direction until the required distance. Therefore, when the user grinds coffee beans, the distance between the moving blade disc 9 and the fixed blade disc 27 can be adjusted according to the desired particle size of the coffee powder. The blade disc adjustment structure optimizes the blade disc adjustment structure of the existing coffee bean grinder, and improves the leveling accuracy of the blade disc and the convenience of blade disc adjustment.
[0041] In a specific embodiment, the driving assembly 10 includes a second driving member 12 and a driving shaft 13. Among them, a slide groove 15 is provided at one end of the driving shaft 13 connected to the second driving member 12, and the power output end of the second driving member 12 is slidably arranged in the slide groove 15, and the driving shaft 13 can move horizontally, and the driving shaft 13 is fixedly connected to the moving blade disc 9. In this embodiment, the second driving member 12 is a motor. When using the coffee bean grinder to grind coffee, the motor is started, and the power output end of the motor drives the driving shaft 13 to rotate, and then drives the moving blade disc 9 to rotate, thereby grinding the coffee beans.
[0042] In a specific embodiment, the leveling assembly 11 includes a leveling screw 20, a leveling inner ring 21, a leveling spring 22 and a driven connecting member 23. The leveling inner ring 21 is fixedly sleeved on the outside of the second driving member 12, and the leveling inner ring 21 is fixedly connected to the top of the base 2. The driven connecting member 23 is fixedly sleeved on the outside of the driving shaft 13 near one end of the second driving member 12, and the end of the leveling screw 20 with a thread penetrates the leveling inner ring 21 and is threadedly connected to the driven connecting member 23. The leveling spring 22 is sleeved on the leveling screw 20, and the two ends of the leveling spring 22 abut against the driven connecting member 23 and the leveling inner ring 21 respectively. In this embodiment, the number of the leveling screws 20 is set to three, and the three leveling screws 20 are equidistantly arranged on the leveling inner ring 21 along the circumferential direction, so as to improve the leveling accuracy of the movable cutter disc 9 and the fixed cutter disc 27.
[0043] Furthermore, the driven connecting member 23 includes a grinding chamber outer ring 24, a sliding pin 25 and a bearing member 26 which are fixedly connected in sequence. The bearing member 26 is fixedly sleeved on the end of the driving shaft 13 close to the second driving member 12, the end of the leveling screw 20 with a thread is threadedly connected in the sliding pin 25, and the two ends of the leveling spring 22 respectively abut against the sliding pin 25 and the leveling inner ring 21. Corresponding to the number of the leveling screws 20, the number of the sliding pins 25 is set to three, and the three sliding pins 25 are fixed at equal distances between the grinding chamber outer ring 24 and the bearing member 26.
[0044] In this regard, after the coffee bean grinder is assembled, the user can rotate the end of the leveling screw 20 away from the sliding pin 25, so that the leveling screw 20 is threadedly connected with the sliding pin 25, and the sliding pin 25 is driven to slide horizontally in the direction close to the leveling screw 20, so that the sliding pin 25 drives the grinding chamber outer ring 24 and the bearing member 26 to slide in the direction close to the second driving member 12, and then the driving shaft 13 drives the movable cutter disc 9 to slide in the direction close to the fixed cutter disc 27. At this time, the sliding force of the sliding pin 25 is greater than the abutting elastic force of the leveling spring 22, and the leveling spring 22 has a buffering effect on the sliding of the sliding pin 25, which can improve the sliding stability of the sliding pin 25. When the movable cutter disc 9 and the fixed cutter disc 27 are close to each other, the parallelism between the movable cutter disc 9 and the fixed cutter disc 27 is in a leveled state.
[0045] In a specific embodiment, the first follower 30 includes a threaded ring 34 and a threaded outer ring 35. The threaded outer ring 35 is rotatably connected to the outer peripheral wall of the leveling inner ring 21, the threaded ring 34 is fixedly sleeved on the outer peripheral wall of the threaded outer ring 35, the first driving member 29 is threadedly connected to the outer peripheral wall of the threaded ring 34, and the outer peripheral wall of the threaded outer ring 35 away from the threaded ring 34 is threadedly connected to the second follower 31.
[0046] The second follower 31 includes a bean-feeding grinding chamber 16 and a grinding spring 17, wherein the bean-feeding grinding chamber 16 is sleeved on the outside of the sliding pin 25, the feed thread 14, and the threaded outer ring 35. A shaft sleeve 8 is sleeved between the sliding pin 25 and the bean-feeding grinding chamber 16, and the bean-feeding grinding chamber 16 and the shaft sleeve 8 are horizontally slidably connected to the sliding pin 25, and the inner peripheral wall of the bean-feeding grinding chamber 16 is threadedly connected to the outer peripheral wall of the threaded outer ring 35. The shaft sleeve 8 can reduce the friction between the bean-feeding grinding chamber 16 and the sliding pin 25, so that the sliding of the bean-feeding grinding chamber 16 is smoother. The two ends of the grinding spring 17 are respectively abutted against the grinding chamber outer ring 24 and the bean-feeding grinding chamber 16, and one side of the bean-feeding grinding chamber 16 is fixedly connected to the fixed blade disc 27. The grinding spring 17 has a buffering effect on the sliding of the bean-feeding grinding chamber 16, which can improve the sliding stability of the bean-feeding grinding chamber 16.
[0047] In this embodiment, a feed channel 19 connected to the feed port 7 is provided on the top of the bean feeding and grinding bin 16, and coffee beans can enter the gap between the feed threads 14 through the feed port 7 and the feed channel 19. When the second driving member 12 drives the driving shaft 13 to rotate, the driving shaft 13 drives the feeding threads 14 to rotate, and then the coffee beans are fed into the grinding gap 3 for grinding.
[0048] Please refer to Figure 6 and Figure 7 In a specific embodiment, the first driving member 29 includes a driving worm 32 and a driving device 33, the power output end of the driving device 33 is connected to the driving worm 32, and the driving worm 32 is threadedly connected to the thread ring 34. In this embodiment, the driving device 33 includes a motor and a synchronous belt, and the synchronous belt is rotatably connected to the power output end of the motor and one end of the driving worm 32 respectively. Therefore, starting the motor to drive the synchronous belt to rotate can drive the driving worm 32 to rotate, and then drive the thread ring 34 to rotate. In other embodiments, the driving device 33 can also be other structures, for example, the power output end of the motor is directly connected to one end of the driving worm 32, or the power output end of the motor is connected to one end of the driving worm 32 through a worm gear, and so on.
[0049] In this regard, when the user adjusts the distance between the moving cutter disc 9 and the fixed cutter disc 27, the driving device 33 is first started to drive the driving worm 32 to rotate, so as to drive the threaded ring 34 and the threaded outer ring 35 to rotate synchronously, and the threaded outer ring 35 is threadedly connected with the bean-feeding grinding bin 16 to drive the bean-feeding grinding bin 16 to slide horizontally toward or away from the threaded outer ring 35, and then the bean-feeding grinding bin 16 drives the fixed cutter disc 27 to slide horizontally toward or away from the moving cutter disc 9 until the required distance is reached. At this time, under the limiting action of the leveling component 11, the driving component 10 and the moving cutter disc 9 are fixed, and the parallelism between the moving cutter disc 9 and the fixed cutter disc 27 can be maintained to adjust the distance between the moving cutter disc 9 and the fixed cutter disc 27.
[0050] In a specific embodiment, the distance detection components are respectively arranged on the grinding bin outer ring 24 and the bean-feeding grinding bin 16. Specifically, the distance detection components include a Hall plate 36 and a magnet 38. The Hall plate 36 is fixed to the side of the grinding bin outer ring 24 facing the bean-feeding grinding bin 16. An IC component 37 (i.e., a semiconductor component) connected to the control system is arranged on the Hall plate 36. The magnet 38 is fixed to the side of the bean-feeding grinding bin 16 close to the grinding bin outer ring 24, and the positions of the IC component 37 and the magnet 38 correspond to each other.
[0051] The IC element 37 is used to detect the magnetic signal of the magnet 38. When the user adjusts the distance between the moving blade disc mechanism and the fixed blade disc mechanism, the distance between the magnet 38 and the IC element 37 will change with the left and right movement of the bean inlet grinding chamber 16, so the accurate distance change can be calculated. There are multiple groups of magnets 38 and IC elements 37, and each group of magnets 38 and IC elements 37 are arranged at an equal distance. In this embodiment, there are three groups of IC elements 37 and magnets 38, and the three groups of IC elements 37 and magnets 38 are arranged at an equal distance, so the parallelism change of the moving blade disc mechanism and the fixed blade disc mechanism can also be calculated.
[0052] The Hall plate 36 is equipped with a linear Hall sensor, which can output voltage according to the Hall effect between the magnetic field of the magnet 38 and the IC element 37. After calibration with the actual distance, the voltage and the distance can be one-to-one correspondence, so that the control system can obtain actual distance feedback, thereby closing the system loop and improving control accuracy. Furthermore, a display screen is provided on the outside of the grinder body, which can display data such as distance change and parallelism change.
[0053] Furthermore, the coffee bean grinder also includes a display screen, wherein the display screen is arranged on the cover 1 or the base 2, and the distance measuring component is electrically connected to the display screen, so that the distance measuring component displays the measured distance change on the display screen, and the user can intuitively see the adjustment distance of the movable blade disc 9 and the fixed blade disc 27 each time.
[0054] In a specific embodiment, the cover body 1 includes a cover body 5 and a rear cover body 6. The rear cover body 6 is provided outside the fixed blade disc mechanism, the cover body 5 is provided outside the movable blade disc mechanism, the feed port 7 is formed at the top of the rear cover body 6, and the discharge port 8 is formed at the bottom of the cover body 5. In addition, the cover body 5 is detachably connected to the rear cover body 6 through a locking buckle 4, so that the user can remove the cover body 5 by himself and regularly clean the movable blade disc 9 and the fixed blade disc 27, thereby improving the grinding accuracy of the coffee beans. In other embodiments, the connection between the cover body 5 and the rear cover body 6 can also be threaded connection, screw connection, etc.
[0055] Embodiment 2 of the present application provides a method for using a distance-measuring coffee bean grinder, which can be applied to the coffee bean grinder. Specifically, the method includes the following steps:
[0056] S1. Start the leveling component 11, which drives the driving component 10 to slide, and the driving component 10 drives the movable cutter disc 9 to move toward the fixed cutter disc 27 until the movable cutter disc 9 is close to the fixed cutter disc 27, which is a leveling state.
[0057] Specifically, when the user assembles the coffee grinder for the first time, the user can rotate the end of the leveling screw 20 away from the sliding pin 25, so that the screw is threadedly connected with the sliding pin 25, and the sliding pin 25 is driven to slide horizontally in the direction close to the leveling screw 20, so that the sliding pin 25 drives the grinding chamber outer ring 24 and the bearing member 26 to slide in the direction close to the second driving member 12, and then the driving shaft 13 drives the movable cutter disc 9 to slide in the direction close to the fixed cutter disc 27. When the movable cutter disc 9 and the fixed cutter disc 27 are close to each other, the parallelism between the movable cutter disc 9 and the fixed cutter disc 27 is in a leveled state.
[0058] S2. Adjust the distance between the moving blade disc 9 and the fixed blade disc 27 according to the type of coffee beans being ground.
[0059] In order to improve the flavor of coffee, different coffee bean powders need to be ground into different coarsenesses. Therefore, when the user replaces the coffee beans, the distance between the movable blade disc 9 and the fixed blade disc 27 needs to be adjusted.
[0060] S3, start the first driving member 29, the first driving member 29 drives the threaded ring 34 and the threaded outer ring 35 to rotate, the threaded outer ring 35 is threadedly connected with the bean inlet and grinding bin 16 to drive the bean inlet and grinding bin 16 to slide leftward or rightward, and the bean inlet and grinding bin 16 drives the fixed blade disc 27 to approach or move away from the movable blade disc 9 until the required distance is reached.
[0061] When the user adjusts the distance between the movable cutter disc 9 and the fixed cutter disc 27, the driving device 33 is first started to drive the driving worm 32 to rotate, so as to drive the threaded ring 34 and the threaded outer ring 35 to rotate synchronously. The threaded outer ring 35 is threadedly connected with the bean inlet and grinding bin 16 to drive the bean inlet and grinding bin 16 to slide horizontally toward or away from the threaded outer ring 35, and then the bean inlet and grinding bin 16 drives the fixed cutter disc 27 to slide horizontally toward or away from the movable cutter disc 9 until the desired distance is reached.
[0062] S4, starting the driving assembly 10, and the driving assembly 10 drives the movable blade disc 9 to rotate relative to the fixed blade disc 27 to grind the coffee beans.
[0063] After the user adjusts the distance between the movable blade disc 9 and the fixed blade disc 27, the second driving member 12 is started, and the power output end of the second driving member 12 drives the driving shaft 13 to rotate, thereby driving the movable blade disc 9 to rotate relative to the fixed blade disc 27, thereby grinding the coffee beans into coffee powder.
[0064] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application.
