[0045] Reference Figure 1-7 , is a structural diagram of a coffee bean grinder in an embodiment of the present application;

[0046] Embodiment 1

[0047] A coffee bean grinder, comprising:

[0048] A shell 9, wherein the shell 9 comprises a processing portion and a discharging portion, wherein the processing portion is disposed above the shell 9, and the discharging portion is disposed below the shell 9, and the processing portion has a recess, and the recess is used to assemble coffee beans;

[0049] A program component 20, the program component 20 includes an adjustment button, a display screen, and an internal circuit board, the adjustment button and the display screen are arranged on the processing part and face the user, and the circuit board is built into the housing 9;

[0050] A grinding part, the grinding part comprises a grinding seat 6, a coarse and fine motor 8, a grinding motor 18, a main shaft 17, an adjustment gear 5, a large gear 4, a potentiometer gear 7, a grinding disc seat 2 and a fixed grinding disc 1;

[0051] The grinding seat 6 is located in the processing part, the large gear 4 is sleeved on the grinding seat 6 and the center position is adapted to the grinding knife 16 exposed from the grinding seat 6, the output end of the coarse and fine motor 8 is connected to the adjusting gear 5, the adjusting gear 5 is meshed with the large gear 4, the potentiometer gear 7 is meshed with the other side of the large gear 4 relative to the adjusting gear 5, the grinding disc seat 2 is sleeved on the large gear 4, the fixed grinding disc 1 is embedded in the grinding disc seat 2 and adapted to the grinding seat 6, the grinding motor 18 is arranged below the grinding seat 6, the output end of the grinding motor 18 is connected to one end of the main shaft 17, and the other end of the main shaft 17 is adapted to the grinding knife 16 at the center of the grinding seat 6;

[0052] An assembly, the assembly comprising a cup holder 19, a weighing bracket 15, a weighing plate 11, a weighing chip 13 and a weighing sensor 12;

[0053] The weighing sensor 12 is arranged in the discharging part, one side of the top of the weighing sensor 12 is connected to the weighing platen 11, and the other side of the weighing sensor 12 is connected to the weighing bracket 15, and the cup holder 19 is adapted to the weighing bracket 15.

[0054] In this embodiment, the grinding member further includes a grinding disc fixing ring, a grinding disc protrusion and an external clamping groove 10;

[0055] The grinding disc fixing ring is sleeved on the outer edge of the grinding disc seat 2 and abuts against the large gear 4, the grinding disc protrusion is arranged on the outer side of the grinding disc fixing ring, the outer groove 10 is arranged on the inner side wall of the processing part, and the grinding disc protrusion is adapted to the outer groove 10.

[0056] Specifically,

[0057] The coffee beans enter the recess at the top of the shell 9 and fall into the fixed grinding disc 1 and the grinding disc seat 2 in the processing part for grinding. After grinding, they are weighed by the weighing sensor 12 and then output to the coffee cup of the cup holder 19 outside. When the coffee powder is output, the weighing sensor 12 will measure the weight of the output coffee powder. When the corresponding weight is reached, the grinding motor 18 will sense the electrical signal and stop the output and the rotation of the grinding knife 16.

[0058] Among them, the adjusting gear 5 is the input power source, which meshes with the outer gear of the large gear 4. When the adjusting gear 5 rotates, the large gear 4 also rotates; the large gear 4 has an internal thread that meshes with the external thread of the grinding seat 6. When the large gear 4 rotates, due to the thread matching between the large gear 4 and the grinding seat 6, the large gear 4 will rise or fall, that is, when the adjusting gear 5 rotates, the large gear 4 will produce a spiral motion;

[0059] The potentiometer gear 7 is meshed with the outer gear of the large gear 4. When the large gear 4 rotates, the potentiometer gear 7 also rotates. Since the large gear 4 is driven by the adjusting gear 5, that is, the rotation of the potentiometer gear 7 is related to the adjusting gear 5, by setting the resistance of the two extreme positions of the potentiometer under the potentiometer gear 7 in the program, the large gear 4 and the potentiometer gear 7 can be controlled to rotate within a certain set angle range, that is, the system will cut off the power input of the motor when the large gear 4 and the potentiometer gear 7 rotate to the extreme position;

[0060] The grinding disc seat 2 is pressed on the large gear 4 through the grinding disc seat fixing ring 3, that is, the grinding disc seat 2 can rotate around the grinding disc seat fixing ring 3, and the grinding disc seat fixing ring 3 is connected to the large gear 4 as a whole; Figure 2 The protrusion at the grinding disc convex block of the grinding disc seat 2 is matched with the groove of the outer card slot 10 of the housing 9, and the rotation of the grinding disc seat 2 is limited by the outer card slot 10. Figure 1 When the large gear 4 moves spirally, the grinding disc seat 2 is restricted from rotating, and the grinding disc seat 2 will only move up or down along the groove for a short stroke;

[0061] The material of the top of the grinding disc seat 2 is soft, that is, it has a certain elasticity. The top of the grinding disc seat 2 matches with the top of the shell 9 to seal the inside of the shell 9. When the grinding disc seat 2 moves upward or downward, due to the material characteristics of the top of the grinding disc seat 2, the sealing of the inside of the shell 9 can be maintained to prevent the fine powder generated in the grinding chamber from invading the body due to static electricity;

[0062] It is particularly important that during the normal grinding process of the coffee machine, the cup holder 19 is rigidly connected to the weighing bracket 15 and maintains a certain gap with the housing 9, so the cup holder 19 and the weighing bracket 15 are only subject to their own gravity. Due to the cantilever structure, the change in their gravity will be directly transmitted to the weighing chip 13. When the powder receiving container is installed on the cup holder 19, the weight G of the coffee powder will increase accordingly, and then be transmitted to the weighing sensor 12, so as to detect the current weight of the coffee powder;

[0063] During normal use, after the cup holder 19 is hung up, the user will inevitably touch the cup holder 19, which will generate a force on the cup holder 19. When the horizontal force F is applied, the force will also be transmitted to the weighing chip 13. In order to protect the weighing chip 13 from being damaged by excessive horizontal force, the distance between the cup holder 19 and the outer shell 9 is appropriately reduced to protect the weighing chip 13. The tail of the cup holder 19 reduces the gap between the outer shell 9.

[0064] In this embodiment, the middle portion 14 of the weighing sensor 12 is hollow, and the weighing sensor 12 is made of a soft material with elastic recovery.

[0065] Specifically, when subjected to external force, the periphery of the middle portion 14 will be deformed. At the middle portion 14, weighing chips 13 for detecting tiny deformations are arranged above and below. The magnitude of the deformation corresponds to the magnitude and direction (vertical direction) of the force applied to the module through an algorithm, thereby calculating the weight of the coffee powder.

[0066] Figure 4 As shown, the left side of the dotted line of the mechanism is connected to the shell 9 and needs to maintain a static state in order to provide sufficient supporting force N. The right side is connected to the bracket as a whole and is used to measure the size of the external force F (i.e. the weight of the peeled coffee powder). Note: When on the right side, in order to ensure the accuracy of the measurement data, it is necessary to ensure that the right side of the weighing sensor 12 and the bracket are only subjected to the external force F in the vertical direction, so the right side of the weighing sensor 12 and the weighing bracket 15 need to be suspended, that is, a certain gap should be maintained between the right side of the weighing sensor 12 and the weighing bracket 15 and the shell 9.

[0067] In this embodiment, the assembly further includes a drip tray, which is disposed below the cup holder 19 .

[0068] Specifically, the drip tray is disposed below the cup holder 19, and if the coffee powder is electrostatically adsorbed or accidentally scattered by the user, the loose powder can be collected on the drip tray;

[0069] The drip tray is held under the cup holder 19 by magnetic attraction. During use, powder may fly due to static electricity, or excessive powder may slip from the mouth of the container, or residual powder may fall from the powder guide tube due to desktop vibration after use. The drip tray is used to collect the fallen coffee powder. The drip tray can be easily removed and installed for easy cleaning.

[0070] A coffee bean grinder, the system comprising:

[0071] A weighing module, which is used to weigh the coffee powder;

[0072] A calculation module, wherein the calculation module is used to weigh the net weight of the coffee powder;

[0073] A preset module, wherein the preset module is used to set different measurement standards.

[0074] The weighing module includes at least one load weighing sensor 12, and the load weighing sensor 12 is configured to detect the weight of coffee powder placed thereon and convert the weight into an electrical signal.

[0075] The calculation module is used to receive the signal related to the mass of the coffee powder generated by the weighing module, and calculate the total weight of the coffee powder based on the signal, and subtract the preset container weight from the total weight to obtain the net weight of the coffee powder.

[0076] The preset module is used to set the weight measurement standard according to different user usage habits.

[0077] Specifically, there are 4 key settings on the adjustment button, which are three buttons and a knob, from left to right, they are weight adjustment button, cup number adjustment button, coarseness adjustment button and knob;

[0078] The operation method is:

If there is no other operating system within three seconds after setting, the setting will be automatically recorded and other operations can be performed.

[0084] Long press for 2 seconds: It only works in the middle gear, switching between the two icons, the system default gear, and the switching is remembered;

[0085] Coarse and fine adjustment button

[0086] Press once: The number at the weight (GRIND SIZE) position starts to flash. You can then rotate the knob to adjust the coarseness and fineness. When the adjustment is in place, the number will no longer flash and you can perform other operations.

[0087] Knobs

[0088] Rotate left and right: set the weight, the coarseness of the grinding, and the number of cups;

[0089] Click: It is the start and stop button of the grinding mill. Press it once to start the machine, and press it a second time to stop the machine. The machine will directly cancel the current operation and enter the standby state.

[0090] Entering manual mode: At this time, the SHOTS / CUPS numbers are not displayed, and the machine can grind continuously. "GRINDWEIGHT" will display the real-time grinding weight until you release your finger, then the display before manual mode will be restored and the machine will enter standby mode.

[0091] Note: Each time you press the middle button to start the work, the currently read weight value will be cleared and the weight will be read again from "0";

[0092] in addition,

[0093] Electronic parameters:

[0094] Adjustable gear: 1~45 (by potentiometer rotation angle / 9K′Ω resistor average distribution);

[0095] Potentiometer gear parameters: can rotate 10 circles, resistance 0~10K′Ω);

[0096] After installation, the potentiometer gear can rotate 9 times;

[0097] Potentiometer gear starting point positioning / limit position: 0.5 circle (500'Ω+ / -100'Ω);

[0098] Potentiometer gear end position / limit position: 9.5 turns (9.5K′Ω);

[0099] Espresso: 1~30, 5 levels in total, 1 level every 6 levels;

[0100] Drip / K-cup: 31~40, 5 levels in total, 1 level every 2 levels;

[0101] French Press: 41~45, 5 levels in total, 1 level per level;

[0102] Mechanical parameters:

[0103] Rotation range of large gear 4: 324°;

[0104] Number of rotating teeth within adjustable range: 54;

[0105] The rotation angle of large gear 4 per gear is 7.2°, equivalent to 1.2 teeth;

[0106] Each rotation of one tooth is equivalent to a rotation of 6°.

[0107] Normal operation process: the user adds an appropriate amount of coffee beans to the concave part of the processing part, first presses the coarseness adjustment button to activate the coarseness adjustment of the coffee powder; when the coarseness gear number on the LCD screen flashes, turn the knob to adjust to the desired gear 8, the potentiometer resistance corresponding to the 8th gear set in the program is 1932'Ω (45 gears actually correspond to 44 intervals, and the resistance change corresponding to each interval is 9000 / 44=204.5'Ω, and the resistance of the 8th gear is equal to the starting resistance of the 1st gear 500'Ω+7*204.5=1932'Ω), the circuit board will give instructions to the coarseness motor 8 according to the input of the 8th gear, and the resistance of the potentiometer gear 7 is adjusted to 193 through the adjustment gear 5. 2′Ω, thereby adjusting the large gear 4, the grinding disc seat 2, and the fixed grinding disc 1 to the specified height position. At this time, the gear number 8 on the screen no longer flashes, indicating that the coarseness adjustment has been completed, and the corresponding coffee powder is suitable for Espresso brewing. If the user rotates the knob excessively when adjusting the coarseness and fineness, due to the limitation of program settings, the coarseness and fineness gear numbers displayed on the screen can be adjusted to the two extreme ends of 1st gear or 45th gear (depending on the rotation direction of the adjustment knob), and the adjustment motor will only adjust the resistance of the potentiometer gear 7 to 500′Ω or 9500′Ω according to the gear command of the circuit board, so that the height position of the large gear 4, the grinding disc seat 2 and the fixed grinding disc 1 will be adjusted to the extreme low position or extreme high position.

[0108] The next step is to adjust the number of cups / cups, which is also a rough adjustment of the powder output weight; click the cup adjustment button, rotate the knob to adjust the number of cups to 6 cups, and the set weight of each cup of Espresso coffee powder in the program is 11.5g, so the total weight is 6*11.5=69g. When the number of cups / cups on the screen stops flashing, the adjustment is complete; similarly, because of the program settings, the number of cups in the Espresso gear can only be adjusted from 1 to 8;

[0109] The weight adjustment is to meet the different taste preferences of users, and it is also a kind of weight fine-tuning: click the weight adjustment button, rotate the knob to adjust the weight to 80g, which is equivalent to the weight of each cup being (80-69) / 6=1.8g more than the standard setting weight; when the weight number on the screen stops flashing, the adjustment is completed; the adjusted weight will be stored as 11.5+1.8=13.3g per cup; the weight data displayed next time when using the Espresso gear will be based on this multiplied by the number of cups;

[0110] After the above adjustments are completed, you can press the knob to start grinding; the weight of the powder output will be continuously sensed by the weighing sensor 12 and displayed on the screen starting from 0 until the set weight is reached. The circuit board immediately instructs to disconnect the voltage input of the grinding motor 18 and the grinding stops.
