Description

Technical Field

[0001] This application relates to the field of grinding equipment technology, and more particularly to a bean grinding device. Background Technology

[0002] Existing coffee machines with grinding devices mostly have bean hoppers that can only hold one type of coffee bean. However, users with higher taste preferences often need to switch between different flavors of coffee beans or mix them. Current coffee grinding devices that can supply multiple flavors require multiple bean hoppers, resulting in complex structures, inconvenient operation, large size, and high cost. For example, Chinese patent CN1931068A discloses a coffee bean dispensing method, an automatic coffee machine using this method, and coffee bean hoppers. The machine body has multiple bean hoppers for holding different types of coffee beans. Each hopper includes a body with an outlet at the bottom and a bean quantity adjustment hopper that can rotate relative to the body. The adjustment hopper has an opening; when the opening connects to the outlet at the bottom of the bean hopper, coffee beans fall into the bean quantity adjustment hopper; when the opening rotates to the bottom, the coffee beans in the adjustment hopper fall out. It is evident that this automatic coffee machine has multiple coffee bean bins. When switching to different flavors of coffee beans, it is necessary to change to the corresponding bean bin, which is not only inconvenient to operate, but also has a large structural size and takes up a lot of space. Utility Model Content

[0003] To address the aforementioned technical problems in the prior art, this application provides a coffee grinding device, the interior of which is divided into several bean hoppers. This design allows for a compact structure of the bean hopper assembly, eliminating the need for multiple hoppers and reducing the space required for the grinding device. Furthermore, it enables separate feeding of materials through different bean hoppers, thereby facilitating the rapid switching of materials with different flavors and the mixing of different materials.

[0004] This application provides a bean grinding device, which includes a bean hopper assembly and a lid assembly. The bean hopper assembly includes at least a hopper body, which is divided into at least two independently arranged bean bins. Each bean bin has a first discharge port at its bottom. The lid assembly includes a first cover and a second cover rotatably disposed at the bottom of the hopper body. The first cover and the second cover are arranged sequentially from top to bottom. The first cover has a second discharge port corresponding to each of the first discharge ports, and the first cover is used to rotatably open or close the first discharge ports of each bean bin. The second cover has a third discharge port corresponding to one of the first discharge ports, and the second cover is used to rotate to connect the third discharge port with one of the first discharge ports, so that after the first cover opens each of the first discharge ports, the bean material is discharged through the bean bin communicating with the third discharge port. The aforementioned box is divided into several bean hoppers, which makes the structure of the bean box assembly as compact as possible. It eliminates the need for multiple boxes, reduces the space required for the grinding device, and allows for separate feeding of beans through different hoppers, enabling quick switching between different flavors and mixing of different ingredients.

[0005] In some embodiments, the grinding device further includes an actuation component and a control component electrically connected. The actuation component drives the first and second covers to rotate relative to the housing. The control component controls the first cover to rotate and seal each of the first discharge ports, and then controls the second cover to rotate to a position where the third discharge port communicates with one of the first discharge ports. Thus, precise control of the rotation angle of the first and second covers can be achieved through the control of the actuation component by the control component.

[0006] In some embodiments, the lid assembly further includes a first switch element, the second lid body is provided with a first trigger element, and the second lid body has a first origin position. The first trigger element is used to trigger the first switch element at the first origin position. In this way, the first switch element can accurately identify whether the second lid body is at the first origin position, that is, detect whether the second lid body has returned to the first origin position, thereby achieving accurate identification of the rotational position of the second lid body.

[0007] In some embodiments, the lid assembly further includes a second switch element. The second lid body has a second trigger portion and an endpoint position. The second lid body moves between a first origin position and the endpoint position. The second trigger portion is used to trigger the second switch element at the endpoint position. Thus, the second switch element can accurately identify that the second lid body is at the endpoint position, thereby achieving accurate identification of the rotational position of the second lid body.

[0008] In some embodiments, the lid assembly further includes a third switch element. The first lid body is provided with a third trigger part, and the first lid body has a second origin position. The third trigger part is used to trigger the third switch element at the second origin position. In this way, the third switch element can accurately identify whether the first lid body is at the second origin position, that is, detect whether the first lid body has returned to the second origin position, thereby achieving accurate identification of the rotational position of the first lid body.

[0009] In some embodiments, when the number of bean hoppers is three or more, each bean hopper includes a first hopper body, a second hopper body, and at least one third hopper body. The first hopper body is correspondingly disposed with a third discharge port on the second cover body at the first origin position, and the second hopper body is correspondingly disposed with a third discharge port on the second cover body at the end position. The at least one third hopper body is located between the first hopper body and the second hopper body along a first direction. The lid assembly also includes a photoelectric switch corresponding to the third hopper body, which is used to detect the position information of the third discharge port corresponding to the third hopper body. The first direction is the direction of movement of the second cover body from the first origin position to the end position. Thus, when the number of bean hoppers is three or more, the position information of the third discharge port corresponding to the third hopper body can be detected by the photoelectric switch, thereby achieving accurate identification of the rotation position of the second cover body.

[0010] In some embodiments, the grinding device further includes a mounting base, on which the bean hopper assembly is detachably mounted. The bean hopper assembly also includes a bottom structure rotatably connected to the hopper body. The bottom structure has a fourth discharge port corresponding to each of the first discharge ports. When the hopper body is mounted on the mounting base, the fourth discharge port is rotatably opened; when detached from the mounting base, the fourth discharge port is rotatably sealed. The aforementioned hopper body and bottom structure are simple in structure and easy for users to operate.

[0011] In some embodiments, the control component is further configured to, upon receiving a mixing and discharging instruction, control the second cover to rotate sequentially in a preset order to a position where the third discharge port communicates with different first discharge ports, so as to discharge materials through different bean hoppers respectively communicating with the third discharge port. Thus, by controlling the second cover to rotate sequentially in a preset order through the control component, mixing and discharging can be achieved, thereby mixing and grinding materials of different flavors into powder.

[0012] In some embodiments, the grinding device further includes a safety switch assembly, which is disposed at the bottom of the bean container assembly and is used to detect the positioning information of the bean container assembly. Thus, the safety switch assembly can accurately detect whether the bean container assembly is in position, ensuring that the grinding device can proceed with subsequent grinding operations once the bean container assembly is in position.

[0013] In some embodiments, the actuation assembly includes a first actuation group and a second actuation group. The first actuation group includes a first driving member and a first transmission member. The first transmission member interacts with the first cover, and the first driving member drives the first cover to rotate via the first transmission member. The second actuation group includes a second driving member and a second transmission member. The second transmission member interacts with the second cover, and the second driving member drives the second cover to rotate via the second transmission member. The above-described actuation assembly has a simple structure and stable drive, achieving stable rotation of both the first and second covers.

[0014] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: By dividing the bean box assembly into at least two independently arranged bean bins, and by rotating the first cover and the second cover located at the bottom of the box, this application can achieve the simultaneous opening or closing of the first discharge port of each bean bin by the first cover, and selectively opening one of the multiple first discharge ports by the second cover. After the second cover is rotated to connect the third discharge port with one of the first discharge ports, the material is discharged through one of the multiple bean bins. Thus, by rotating the second cover, the material can be discharged through different bean bins, thereby achieving the purpose of quickly switching between materials of different flavors and mixing different materials. Moreover, the division of the box into multiple bean bins can make the structure of the bean box assembly as compact as possible, eliminating the need for multiple boxes and reducing the space required for the grinding device.

[0027] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This application provides a coffee grinding device. For example... Figures 1 to 6As shown, the bean grinding device includes a bean bin assembly 1 and a lid assembly. The bean bin assembly 1 includes at least a body 11, which is divided into at least two independently arranged bean hoppers 12. Each bean hopper 12 has a first discharge port 13 at its bottom. The lid assembly includes a first cover 2 and a second cover 3 rotatably disposed at the bottom of the body 11. The first cover 2 and the second cover 3 are arranged sequentially from top to bottom. The first cover 2 has a second discharge port 21 corresponding to each of the first discharge ports 13, and the first cover 2 is used to rotatably open or close the first discharge ports 13 of each bean hopper 12. The second cover 3 has a third discharge port 31 corresponding to one of the first discharge ports 13. The second cover 3 is used to rotate so that the third discharge port 31 communicates with one of the first discharge ports 13, so that after the first cover 2 opens each of the first discharge ports 13, the bean hopper 12 communicating with the third discharge port 31 discharges the material.

[0029] The aforementioned bean hoppers 12 can be used to hold different materials, such as coffee beans of different flavors. Figure 1 and Figure 5 As shown in the figure, there are three bean hoppers 12. The following explanation will use the example of three bean hoppers 12. For ease of explanation, the three bean hoppers 12 will be named first hopper 14, third hopper 16 and second hopper 15 in reverse order (see below for details).

[0030] The first discharge port 13 and the second discharge port 21 are configured in a one-to-one correspondence. For example, if there are three first discharge ports 13, there are also three second discharge ports 21. The first cover 2 can simultaneously open the first discharge ports 13 of each bean hopper 12. At this time, the second discharge ports 21 on the first cover 2 are configured in a corresponding manner with the first discharge ports 13, and the material in the bean hopper 12 can be discharged from the first discharge ports 13 to the second discharge ports 21. The first cover 2 can also simultaneously close the first discharge ports 13 of each bean hopper 12. At this time, the second discharge ports 21 on the first cover 2 are staggered with the first discharge ports 13, so that the material in the bean hopper 12 cannot be discharged.

[0031] The number of second discharge ports 21 on the first cover 2 is the same as the number n of soybean bins 12. The first cover 2 rotates by an angle of 360° / (2*n) each time, and the bottom of the soybean bin 12 can be opened and closed by rotating the first cover 2. For example, when the number of soybean bins 12 n=3, the first cover 2 rotates by an angle of 60° each time.

[0032] The third discharge port 31 on the second cover 3 can be understood as one, which can be connected to one of the first discharge ports 13 by rotation, so that the bean bin 12 corresponding to the first discharge port 13 connected to the third discharge port 31 can be discharged. Thus, after the bean bin 12 is discharged, the rotation of the second cover 3 can be controlled to discharge the bean bins 12, so that the materials in different bean bins 12 can be mixed.

[0033] The rotation angle Q of the second cover 3 is Q = x * 360° / n; where x is the number of bean hoppers 12 that the second cover 3 spans. For example, when the number of bean hoppers 12 n = 3 and the number of bean hoppers 12 that the second cover 3 spans is 2, the rotation angle Q of the second cover 3 is 240°.

[0034] The aforementioned grinding device may also include a grinding assembly 101, which may include a grinding motor and a blade assembly. After the material discharged from the bean hopper 12 falls into the grinding chamber of the grinding assembly 101, the grinding motor will drive the blade assembly to rotate, so as to grind the material through the blade assembly, such as grinding coffee beans to prepare coffee powder.

[0035] The aforementioned grinding device may further include a hopper level indicator cover 102, a first rotating shaft 103, and a second rotating shaft 104. The hopper level indicator cover 102 rotates synchronously with the second cover 3 to indicate the current discharging hopper 12. The first rotating shaft 103 is inserted into the housing 11, causing the housing 11 to rotate around the first rotating shaft 103. The hopper level indicator cover 102 can be specifically connected to the second cover 3 via the first rotating shaft 103. The aforementioned second rotating shaft 104 can be inserted into the first cover 2 and the second cover 3, causing the first cover 2 and the second cover 3 to rotate around the second rotating shaft 104.

[0036] The aforementioned grinding device may also include a guide 19, which is located at the upper opening of the grinding chamber and is used to guide the material into the grinding chamber.

[0037] This application divides the housing 11 of the bean box assembly 1 into at least two independently arranged bean hoppers 12, and rotates the first cover 2 and the second cover 3 located at the bottom of the housing 11. This enables the first discharge port 13 of each bean hopper 12 to be opened or closed simultaneously by the first cover 2, and the second cover 3 to selectively open one of the multiple first discharge ports 13. After the second cover 3 is rotated to connect the third discharge port 31 with one of the first discharge ports 13, the material is discharged through one of the multiple bean hoppers 12. Thus, by rotating the second cover 3, the material can be discharged through different bean hoppers 12, thereby achieving the purpose of quickly switching between materials with different flavors and mixing different materials. Furthermore, the division of the housing 11 into multiple bean hoppers 12 can make the structure of the bean box assembly 1 as compact as possible, eliminating the need for multiple housings 11 and reducing the space required for the bean grinding device.

[0038] In some embodiments, such as Figures 1 to 6 As shown, the grinding device also includes an actuation component 4 and a control component (not shown in the figure) that are electrically connected. The actuation component 4 is used to drive the first cover 2 and the second cover 3 to rotate relative to the housing 11. The control component is used to control the first cover 2 to rotate and seal each of the first discharge ports 13, and then control the second cover 3 to rotate to a position where the third discharge port 31 communicates with one of the first discharge ports 13.

[0039] In this way, by controlling the actuator 4 through the control component, the rotation angle of the first cover 2 and the second cover 3 can be precisely controlled. This achieves the purpose of first controlling the rotation of the first cover 2 to seal each of the first discharge ports 13, and then controlling the rotation of the second cover 3 to discharge the material, so as to avoid the problem of mis-discharging when the second cover 3 rotates and achieve precise material discharge.

[0040] Understandably, after controlling the second cover 3 to rotate to a position where it communicates with one of the third discharge port 31 and the first discharge port 13, the control component controls the first cover 2 to rotate and open each of the first discharge ports 13, thereby discharging the material through the bean hopper 12 that communicates with the third discharge port 31.

[0041] It should be noted that the control components can be built using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0042] In some embodiments, such as Figures 1 to 5 As shown, the box cover assembly also includes a first switch 5, a first trigger 32 is provided on the second cover 3, and the second cover 3 has a first origin position. The first trigger 32 is used to trigger the first switch 5 at the first origin position.

[0043] In this way, the second cover 3 can be accurately identified as being at the first origin position by the first switch 5, that is, by detecting whether the second cover 3 has been reset to the first origin position, thereby achieving accurate identification of the rotation position of the second cover 3.

[0044] Understandably, the first switch 5 is electrically connected to the control component. After receiving the feedback information sent by the first switch 5, the control component can control the second cover 3 to stop rotating so as to ensure that the second cover 3 is located at the first origin position, and control the second cover 3 to only move in the first direction based on the first origin position of the second cover 3.

[0045] The aforementioned second cover 3 also has an end point position. When the second cover 3 is at the first origin position, it can only rotate in the direction of the end point position of the second cover 3. When the second cover 3 is at the end point position, it can only rotate in the direction of the first origin position of the second cover 3.

[0046] In some embodiments, such as Figures 1 to 5 As shown, the lid assembly also includes a second switch 6. The second cover 3 is provided with a second trigger part, and the second cover 3 also has an end position. The second cover 3 moves between the first origin position and the end position. The second trigger part is used to trigger the second switch 6 at the end position. The second cover 3 can be understood as reciprocating between the first origin position and the end position.

[0047] In this way, the second cover 3 can be accurately identified as being in the end position by the second switch 6, thereby achieving accurate identification of the rotation position of the second cover 3.

[0048] The first trigger part 32 and the second trigger part mentioned above can be the same protrusion on the second cover 3, that is, the first trigger part 32 and the second trigger part have the same structure. Of course, the first trigger part 32 and the second trigger part can also be different protrusions on the second cover 3. This application does not make a specific limitation in this regard, as long as they can stably trigger the first switch 5 and the second switch 6.

[0049] Understandably, the second switch 6 is electrically connected to the control component. After receiving the feedback information sent by the second switch 6, the control component can control the second cover 3 to stop rotating to ensure that the second cover 3 is located at the end position, and control the second cover 3 to move only in the second direction opposite to the first direction based on the end position of the second cover 3.

[0050] In some embodiments, such as Figures 1 to 5 As shown, the box cover assembly also includes a third switch 7. The first cover 2 is provided with a third trigger part 22, and the first cover 2 has a second origin position. The third trigger part 22 is used to trigger the third switch 7 at the second origin position.

[0051] In this way, the first cover 2 can be accurately identified as being in the second origin position by the third switch 7, that is, whether the first cover 2 has been reset to the second origin position, thereby achieving accurate identification of the rotation position of the first cover 2.

[0052] It is understandable that when the first cover 2 is in the second origin position, the first cover 2 seals the first discharge port 13 of each bean hopper 12.

[0053] Understandably, the third switch 7 is electrically connected to the control component. After receiving the feedback information sent by the third switch 7, the control component can control the first cover 2 to stop rotating so as to ensure that the first cover 2 is located at the second origin position, and control the first cover 2 to only move in the direction of opening the first discharge port 13 based on the second origin position of the first cover 2.

[0054] In some embodiments, such as Figures 1 to 5 As shown, when there are three or more bean hoppers 12, each bean hopper 12 includes a first hopper body 14, a second hopper body 15, and at least one third hopper body 16. The first hopper body 14 is correspondingly positioned to the third discharge port 31 on the second cover 3 at the first origin position. The second hopper body 15 is correspondingly positioned to the third discharge port 31 on the second cover 3 at the end position. At least one third hopper body 16 is located between the first hopper body 14 and the second hopper body 15 along a first direction. The cover assembly also includes a photoelectric switch 8 corresponding to the third hopper body 16. The photoelectric switch 8 is used to detect the position information of the third discharge port 31 corresponding to the third hopper body 16. The first direction is the direction of movement of the second cover 3 from the first origin position to the end position. Figures 7 to 9 As shown, Figure 7 The third discharge port 31 shown in the figure is connected to the first chamber 14. Figure 8 The third discharge port 31 shown in the figure is connected to the third compartment 16. Figure 9 The third discharge port 31 shown in the figure is connected to the second chamber 15.

[0055] Thus, when there are three or more bean hoppers 12, the photoelectric switch 8 can detect the position information of the third discharge port 31 corresponding to the third hopper body 16, so as to achieve accurate identification of the rotation position of the second cover 3. That is, when the third discharge port 31 on the second cover 3 rotates to the position corresponding to the third hopper body 16, the photoelectric switch 8 can detect the position of the second cover 3.

[0056] The aforementioned photoelectric switches 8 can be configured in a one-to-one correspondence with the third compartment 16, meaning the number of photoelectric switches 8 is the same as the number of third compartments 16. For example, when the number of bean compartments 12 n=3, the number of third compartments 16 is one, and in this case, there is also one photoelectric switch 8.

[0057] In some embodiments, such as Figures 1 to 6 As shown, the grinding device also includes a mounting base 9, and the bean box assembly 1 is detachably mounted on the mounting base 9. The bean box assembly 1 also includes a bottom structure 17 rotatably connected to the box body 11. The bottom structure 17 has a fourth discharge port 18 that is respectively provided corresponding to each of the first discharge ports 13. When the box body 11 is mounted on the mounting base 9, it rotates to open the fourth discharge port 18, and when it is removed from the mounting base 9, it rotates to seal the fourth discharge port 18.

[0058] In this way, when the box body 11 is detached from the mounting base 9, the bottom structure 17 can prevent the material inside the box body 11 from leaking out. When the box body 11 is installed on the mounting base 9, the fourth discharge port 18 can be opened by rotating the box body 11, so that the material inside the box body 11 can be smoothly discharged through the fourth discharge port 18 on the bottom structure 17. The structure of the box body 11 and the bottom structure 17 is simple and easy for users to operate.

[0059] After the bean box assembly 1 is removed from the mounting base 9, when the bean box assembly 1 is reinstalled on the mounting base 9, the control component can control the second cover 3 to reset to the first origin position and the first cover 2 to reset to the second origin position, so as to achieve precise control over the rotation position of the first cover 2 and the second cover 3.

[0060] The bottom structure 17 and the body 11 of the box can be respectively provided with rotation limiting parts. The rotation limiting parts limit the rotation angle between the bottom structure 17 and the body 11 to ensure that the body 11 can rotate to open or close the fourth discharge port 18.

[0061] In some embodiments, the control component is further configured to, upon receiving a mixing and discharging instruction, control the second cover 3 to rotate sequentially in a preset order to a position where the third discharge port 31 communicates with different first discharge ports 13, so as to discharge materials through different bean hoppers 12 that are respectively connected to the third discharge port 31.

[0062] In this way, the second cover 3 can be controlled by the control component to rotate in a preset order to achieve mixing and feeding, thereby achieving the purpose of mixing and grinding materials with different flavors into powder.

[0063] The aforementioned grinding device may include a control unit, which the user can operate to generate a mixing and discharging command. After the control component receives the mixing and discharging command, it can discharge the material through different bean hoppers 12.

[0064] The aforementioned control component can control the discharge amount by controlling the duration for which the second cover 3 remains in the current discharge position. For example, the discharge amount can be increased by increasing the duration for which the second cover 3 remains in the current discharge position.

[0065] In some embodiments, such as Figures 3 to 5 As shown, the grinding device also includes a protection switch assembly 10, which is located at the bottom of the bean container assembly 1 and is used to detect the position information of the bean container assembly 1.

[0066] In this way, the protection switch assembly 10 can accurately detect whether the bean box assembly 1 is in place, ensuring that the bean grinding device can perform subsequent bean grinding operations after the bean box assembly 1 is in place. For example, the control assembly can control the first cover 2 and the second cover 3 to rotate in sequence through the actuation assembly 4.

[0067] Understandably, the protection switch assembly 10 is electrically connected to the control assembly. After receiving the arrival information sent by the protection switch assembly 10, the control assembly can determine that the bean box assembly 1 has arrived. At this time, it can control the bean grinding device to perform subsequent bean grinding operations, such as controlling the first cover 2 and the second cover 3 to rotate in sequence through the actuation assembly 4.

[0068] In some embodiments, such as Figures 4 to 9 As shown, the actuation assembly 4 includes a first actuation group and a second actuation group. The first actuation group includes a first driving member 41 and a first transmission member 42. The first transmission member 42 interacts with the first cover 2, and the first driving member 41 drives the first cover 2 to rotate via the first transmission member 42. The second actuation group includes a second driving member 43 and a second transmission member 44. The second transmission member 44 interacts with the second cover 3, and the second driving member 43 drives the second cover 3 to rotate via the second transmission member 44. The actuation assembly 4 has a simple structure and stable drive, achieving stable rotation of the first cover 2 and the second cover 3.

[0069] The first transmission member 42 and the second transmission member 44 can both be constructed as transmission teeth. The first cover 2 is provided with a first tooth that meshes with the first transmission member 42, and the second cover 3 is provided with a second tooth that meshes with the second transmission member 44.

[0070] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. Those skilled in the art can make various modifications or equivalent substitutions to this application within the scope and nature of this application, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
