[0001] This utility model relates to the technical field of coffee grinders, and in particular to a coffee grinder and a coffee grinder using the same. Background Technology
[0002] Existing coffee grinders, such as coffee machines, achieve the opening and closing of the bean outlet by loading and unloading the bean hopper from the main body of the grinder. In other words, the closing structure of the bean outlet needs to cooperate with the main body of the grinder to achieve this.
[0003] In addition, the bean hopper structure described above keeps the bean outlet open during use, continuously supplying beans to the grinder, making it impossible to empty the grinding chamber. Furthermore, after the bean hopper is removed, a large amount of coffee beans will remain inside the grinding chamber, making it difficult to clean. Utility Model Content

[0041] Please see Figures 1 to 4 This utility model provides a bean box, which includes a bean hopper 1 and an opening and closing component 2, wherein...
[0042] The bean hopper 1 has an inner cavity 11 and a bean outlet 12 communicating with the inner cavity 11. The bean outlet 12 has a central axis.
[0043] The opening and closing component 2 is configured to rotate relative to the bean bin 1 around the central axis and is partially located outside the inner cavity 11. The opening and closing component 2 includes a number of stop members 21 arranged around the central axis at intervals, and a first row bean gap 22 is formed between two adjacent stop members 21.
[0044] The inner cavity 11 is provided with several fixed arms 13 connected to the bean hopper 1. A second row bean gap 14 is formed between two adjacent fixed arms 13. When the first row bean gap 22 and the second row bean gap 14 are at least partially opposite, the inner cavity 11 is connected to the bean outlet 12.
[0045] In the above design, the opening and closing component 2 is configured to rotate relative to the bean hopper 1 around the central axis, including two cases: one is that the bean hopper 1 is fixed and the opening and closing component 2 rotates itself; the other is that the opening and closing component 2 is fixed and the bean hopper 1 rotates.
[0046] With the above design, when the user manually drives or an external power source drives the opening and closing component 2 located outside the bean hopper 1 (i.e. outside the inner cavity 11), or when the user manually drives the bean hopper to rotate, several stop components 21 can rotate accordingly, so that the first row bean gap 22 and the second row bean gap 14 are staggered or aligned, thereby disconnecting or connecting the first row bean gap 22 and the second row bean gap 14. When the first row bean gap 22 and the second row bean gap 14 are connected, the inner cavity 11 and the bean outlet 12 are connected, and the coffee beans stored in the inner cavity 11 can be discharged from the bean outlet 12 through the first row bean gap 22 and the second row bean gap 14.
[0047] Specifically, a number of stopper components 21 are configured to form a first conical structure 3, and a number of fixed arms 13 are configured to form a second conical structure 4. The first conical structure 3 is rotatably disposed inside the second conical structure 4.
[0048] In this embodiment, three stopper members 21 are provided, and the three stopper members 21 form a first conical structure 3. A first bean-rowing gap 22 is formed between two adjacent stopper members 21. Similarly, three fixing arms 13 are provided, and the three fixing arms 13 form a second conical structure 4. A second bean-rowing gap 14 is formed between two adjacent fixing arms 13. In other words, a complete hollow cone has N cone walls cut off to form N first bean-rowing gaps 22 or N second bean-rowing gaps 14, and N+1 stopper members 21 or N+1 fixing arms 13 are formed. Of course, in this embodiment, in order to achieve good bean-rowing efficiency, the rounded corner between two adjacent first bean-rowing gaps 22 should be consistent with the included angle between two adjacent second bean-rowing gaps 14. Furthermore, it should be clear to those skilled in the art that, based on other requirements, the rounded corner between two adjacent first bean-rowing gaps 22 may not be consistent with the included angle between two adjacent second bean-rowing gaps 14.
[0049] In a more specific embodiment, the opening and closing component 2 further includes an opening and closing member 23, a plurality of stop members 21 are connected to the opening and closing member 23 to rotate synchronously with the opening and closing member 23, and the opening and closing member 23 is at least partially located outside the bean hopper 1, that is, the opening and closing member 23 is at least partially located outside the inner cavity 11.
[0050] With this configuration, the opening and closing component 23 can be manually driven by the user or driven by an external power source, such as a motor or a gear transmission system driven by a motor. Alternatively, the opening and closing component 23 can be connected and fixed to the main body of the grinder, allowing the user to open and close the bean outlet by rotating the bean hopper 1.
[0051] Furthermore, the bean box also includes an axial limiting member 5 and a connecting member 6.
[0052] The axial limiting member 5 is fixedly connected to the bean hopper 1, and a first space 51 is formed between the axial limiting member 5 and the bean hopper 1. The opening and closing member 2 is at least partially disposed in the first space 51, and the axial limiting member 5 is configured to restrict the axial degree of freedom of the opening and closing member 2 along the central axis.
[0053] In this way, the opening and closing component 2 can be installed in the first space 51, and the opening and closing component 2 can only rotate around the central axis, but cannot move axially along the central axis.
[0054] The connecting member 6 is disposed outside the first space 51 and connected to the opening and closing component 2. It is configured to drive the opening and closing component 2 to rotate around the central axis or to fix the opening and closing component 2 in place. The axial limiting member 5 is provided with a clearance part 52. The connecting member 6 can pass through the clearance part 52 to connect with the opening and closing component 2. The clearance part 52 is configured to provide the required rotation angle of the opening and closing component 2. Providing the required rotation angle of the opening and closing component 2 means that the clearance part 52 forms a rotation space with a certain central angle, so that the connection between the connecting member 6 and the opening and closing component 2 can move in the rotation space. The central angle of the rotation space provided by the clearance part 52 can be any angle, such as 60°, 100°, 120°, etc. In this embodiment, since there are 3 gaps in the first row of beans 22 and 3 gaps in the second row of beans 14, there are a total of 2 connections between the connecting member 6 and the opening and closing component 2. Therefore, there are 2 clearance parts 52 symmetrically arranged about the central axis, and the central angle of each clearance part 52 is set to 120°.
[0055] The opening and closing component 23 has a first through hole 24, the axial limiting component 5 has a second through hole 53, and the connecting component 6 has a third through hole 61. The first through hole 24, the second through hole 53, and the third through hole 61 are interconnected and all communicate with the bean outlet 12. In this way, coffee beans can be discharged from the bean outlet 12.
[0056] In addition, this application also provides a coffee grinder, which includes a coffee grinder body 7, a drive module 8, a burr assembly 9, and the aforementioned coffee container.
[0057] Specifically, the main body 7 of the coffee grinder can be provided with a corresponding connecting structure to connect with the connecting member 6 mentioned above, so that the connecting member 6 is not rotatable relative to the main body of the coffee grinder. The user can rotate the bean hopper 1 to make the fixed arm 13 rotate, that is, the fixed arm 13 rotates relative to the opening and closing member 23, thereby opening and closing the bean outlet.
[0058] In this embodiment, the connection structure is a spring snap-fit mechanism. The outer wall of the connecting member 6 is provided with a corresponding groove. The spring snap-fit mechanism can cooperate with the groove to fix the bean box to the main body 7 of the grinder. The spring snap-fit mechanism is a conventional structure in the art and will not be described in detail here.
[0059] Of course, the main body 7 of the grinder should also include a blade assembly and a drive module for moving the blade assembly.
[0060] The main body 7 of the coffee grinder has a grinding chamber 71 and a discharge port 72 connected to the grinding chamber;
[0061] The blade assembly 9 is at least partially disposed in the grinding chamber 71;
[0062] The drive module 8 is configured to drive the cutter assembly 9 to crush the beans entering the grinding chamber 71. The crushed bean powder is discharged through the discharge port 72.
[0063] The above-mentioned structures are those that should be clearly understood by those skilled in the art and can be applied to the main body of the coffee grinder in conjunction with the bean box provided in this application to achieve the coffee grinding function, and will not be described in detail here.
[0064] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
