Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a bean box device and a coffee machine having the same. Background Art

[0002] In the existing bean grinding coffee machine, the bean box is installed above the grinding assembly. When coffee beans are added to the bean box, the coffee beans can fall into the grinding chamber of the grinding assembly and be ground into powder. In order to facilitate the removal and cleaning of the bean box from the bean grinding device, the bean box is usually designed to be detachable.

[0003] In the existing bean box, in order to avoid beans leaking when the bean box is removed, some merchants have set a bean sealing component at the bottom of the bean box. When the bean box is installed on the coffee machine host and rotated a certain angle, the bean sealing component can be driven to open the bean lower hole; when the bean box needs to be removed, the bean box needs to be rotated in the opposite direction to reset it to drive the bean sealing component to close the bean lower hole, and then the bean box can be taken out.

[0004] However, it was found during use that when the bean box was driven to rotate to a certain angle until the bean sealing assembly opened the lower bean hole, the bean box was not positioned and clamped at this time, and the coffee machine would generate large vibrations during use (such as when grinding beans). This vibration could easily cause the bean box to rotate offset, thereby causing the bean sealing assembly to reset and close the lower bean hole, which was quite troublesome. Utility Model Content

[0005] In order to overcome the defects of the above-mentioned prior art, the utility model provides a bean box device and a coffee machine having the same. By setting a positioning clamping structure, when the bean box body is driven to rotate until the bean lowering hole and the bean falling hole are completely connected, the bean box body and the cover plate are positioned and clamped by the positioning clamping structure, thereby preventing the bean box body from being offset and rotating, thereby ensuring stable and reliable bean lowering.

[0043] 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.

[0044] Embodiment 1

[0045] See also Figure 1-6 The utility model provides a bean box device 1, comprising a bean box body 11, a cover plate 12 covering the bottom of the bean box body 11, and at least one blocking piece 13 arranged between the bean box body 11 and the cover plate 12; wherein, a lower bean hole 111 is provided at the center of the bottom of the bean box body 11, and a bean drop hole 121 communicating with the lower bean hole 111 is provided on the cover plate 12, and the bean drop hole 121 is aligned with the center of the lower bean hole 111; the cover plate 12 is rotatably matched with one end of the blocking piece 13, and the bean box body 11 and the other end of the blocking piece 13 are slidably matched through a groove block guide structure. When the bean box body 11 is driven to rotate around the center of the lower bean hole 111 relative to the cover plate 12, the blocking piece 13 can be driven to rotate to open or close the connection between the lower bean hole 111 and the bean drop hole 121.

[0046] Thus, by providing the bean lowering hole 111 at the bottom center of the bean box body 11, when the bean box body 11 is driven to rotate relative to the cover plate 12 around the center of the bean lowering hole 111, it will not drive the coffee beans to move, so that the bean box body 11 is not easy to get stuck, stuck, etc., and the reliability is high. In addition, by providing a blocking piece 13 at the connection between the bean lowering hole 111 and the bean dropping hole 121, the blocking piece 13 is driven to rotate while the bean box body 11 is rotated, so that when the bean box body 11 is loaded and tightened, the blocking piece 13 opens the connection between the bean lowering hole 111 and the bean dropping hole 121 to achieve the passage of coffee beans, and when the bean box body 11 is unscrewed and removed, the blocking piece 13 closes the connection between the bean lowering hole 111 and the bean dropping hole 121 to achieve the blocking of coffee beans, and the bean dropping or bean sealing function is achieved while the bean box body 11 is loaded and unloaded. It is easy to use, simple in structure, and low in manufacturing cost.

[0047] In addition, considering that vibrations may be generated during the grinding of coffee beans, in order to prevent the vibrations from affecting the baffle 13 and causing abnormal movements of the baffle 13, for example, during the vibrations generated by the grinding of coffee beans, the baffle 13 shrinks the communicating diameter of the lower bean hole 111 and the bean drop hole 121, or even closes the communication between the two, thus affecting the normal supply of coffee beans, a positioning clamping structure is designed between the bean box body 11 and the cover plate 12. By using the positioning clamping structure, when the baffle 13 completely opens the communicating portion between the lower bean hole 111 and the bean drop hole 121, the bean box body 11 and the cover plate 12 can be positioned and clamped by the baffle 13, thereby ensuring that after the bean box body 11 is installed and tightened and the baffle 13 opens the communicating portion between the lower bean hole 111 and the bean drop hole 121, the bean box body 11 and the baffle 13 can be kept in the installed and tightened position during the grinding of coffee beans, so as to ensure the normal supply of the coffee beans being ground and ensure stable and reliable bean dropping.

[0048] In this embodiment, two baffles 13 are provided and are arranged symmetrically with each other; when the bean box body 11 rotates relative to the cover plate 12, the two baffles 13 can be driven to move closer to or farther away from each other. When the two baffles 13 move closer to each other, the connection between the lower bean hole 111 and the bean falling hole 121 can be closed; when the two baffles 13 move away from each other, the lower bean hole 111 and the bean falling hole 121 can be connected.

[0049] It should be noted that, in other embodiments, the bean box body 11 may be rotatably matched with one end of the blocking piece 13 , and the slot block guide structure may be disposed between the cover plate 12 and the blocking piece 13 .

[0050] For details, see Figure 1-6 The cover plate 12 is provided with a clamping column 122, and one end of the blocking piece 13 is provided with a clamping hole 131 which can be sleeved on the clamping column 122 to form a rotational fit. The clamping hole 131 is sleeved on the clamping column 122 to form a rotational fit between the two. The slot block guide structure includes a slide groove 132 provided at the other end of the blocking piece 13 and a slider 112 provided at the bottom of the bean box body 11 and slidably provided in the slide groove 132 to form a sliding fit. Therefore, when the bean box body 11 is driven to rotate relative to the cover plate 12, the blocking piece 13 can be driven around the center point of the clamping hole 131, and the slider 112 and the slide groove 132 are guided by the sliding to realize the rotation.

[0051] It should be noted that in other embodiments, the positions of the clamping column 122 and the clamping hole 131 can be interchanged, that is, the clamping hole 131 is designed on the cover plate 12, and the clamping column 122 is designed on the baffle 13; similarly, the positions of the slide groove 132 and the slider 112 in the slot block guide structure can also be interchanged, that is, the slider 112 is designed on the baffle 13, and the slide groove 132 is designed on the bottom of the bean box body 11. And when the bean box body 11 and the baffle 13 are rotationally matched, and the slot block guide structure is arranged between the cover plate 12 and the baffle 13, the specific rotationally matched clamping hole and clamping column structure can be one of the bottom of the bean box body 11 and the baffle 13, and correspondingly, the slide groove and slider structure of the slot block guide structure can be on the other of the cover plate 12 and the baffle 13, and the details are not repeated here.

[0052] In this embodiment, the slide groove 132 is in the shape of a waist-shaped hole, so as to facilitate the synchronous rotation smoothness of the blocking piece 13 when the bean box body 11 is rotated.

[0053] See also Figure 1-6Furthermore, the positioning snap-fit ​​structure includes at least two positioning blocks 113 and at least one elastic snap 123. One of the bean box body 11 and the cover plate 12 is provided with the positioning block 113, and the other of the bean box body 11 and the cover plate 12 is provided with the elastic snap 123. Specifically, at least two positioning blocks 113 are designed at the bottom of the bean box body 11 and at least one elastic snap 123 is designed on the cover plate 12. When the bean box body 11 is driven to rotate relative to the cover plate 12 until the blocking piece 13 completely opens the connection between the lower bean hole 111 and the bean falling hole 121, the elastic snap 123 is snapped with one positioning block 113; when the bean box body 11 is driven to rotate in the opposite direction relative to the cover plate 12 until the blocking piece 13 completely closes the connection between the lower bean hole 111 and the bean falling hole 121, the elastic snap 123 is snapped with the other positioning block 113.

[0054] Therefore, by providing a positioning clamping structure and designing at least two positioning blocks 113 in the positioning clamping structure, when the bean box body 11 is driven to rotate until the bean lowering hole 111 and the bean falling hole 121 are completely connected or completely closed, the two positioning blocks 113 are respectively clamped with the elastic buckles 123, so that the positioning clamping between the bean box body 11 and the cover plate 12 can be maintained in both the connected and closed states of the bean lowering hole 111 and the bean falling hole 121, which can prevent the blocking piece 13 from being offset and rotated due to grinding vibration or user's accidental touch when the bean lowering hole 111 and the bean falling hole 121 are connected to drop beans, thereby maintaining reliable connection between the two and allowing normal passage of coffee beans; and preventing the blocking piece 13 from being offset and rotated due to other vibrations of the coffee machine or user's accidental touch when the bean lowering hole 111 and the bean falling hole 121 are closed and sealed, thereby maintaining reliable closure of the two, ensuring reliable blocking of coffee beans, and ensuring stable and reliable bean dropping and sealing.

[0055] Preferably, the number of the positioning blocks 113 is four, and the four positioning blocks 113 are arranged 90 degrees apart from each other along the circumferential direction, and the number of the elastic buckles 123 is two and they are arranged 180 degrees apart from each other.

[0056] Therefore, by providing a plurality of positioning blocks 113 and a plurality of elastic buckles 123, the snap connection is made more stable and firm, the stability of the bean box body 11 and the position stability of the blocking piece 13 are further improved, and the reliability of bean feeding and bean sealing is improved.

[0057] It should be noted that in other embodiments, the positioning block 113 and the elastic buckle 123 may be interchanged, that is, the positioning block 113 may be disposed on the cover plate 12, and the elastic buckle 123 may be disposed on the bottom of the bean box body 11, which can also achieve the same technical effect, and is not limited here.

[0058] Specifically, the positioning block 113 is provided with a first arc surface 1131 on both sides, and the elastic buckle 123 is provided with a second arc surface 1231 matching the first arc surface 1131 on both sides. When the bean box body 11 rotates relative to the cover plate 12, the positioning block 113 and the elastic buckle 123 can be driven to disengage through the abutment and cooperation between the first arc surface 1131 and the second arc surface 1231.

[0059] It should be noted that in other embodiments, the arc surface may be changed to an inclined surface, which can also achieve the effect of separating the positioning block 113 from the elastic buckle 123, which is not limited here.

[0060] Embodiment 2

[0061] See also Figure 7-8 The utility model also provides a coffee machine, comprising a frame 2 and a bean box device 1 arranged on the frame 2, wherein a through slot 21 is provided on the frame 2, and the bottom of the bean box body 11 can be detachably screwed into and assembled in the through slot 21. Specifically, a guide slot 22 and a clamping slot 23 are provided on the inner side wall of the through slot 21, wherein the guide slot 22 extends in the circumferential direction, and the clamping slot 23 is located below the end of the guide slot 22 and communicates with the guide slot 22; a first clamping block 114 slidably matched with the guide slot 22 is provided on the outer side wall of the bean box body 11, and a second clamping block 124 tightly matched with the clamping slot 23 is provided on the outer side wall of the cover plate 12.

[0062] When the bean box body 11 is placed into the through slot 21, the first clamping block 114 is clamped into the guide slide slot 22, and the second clamping block 124 is clamped into the clamping slot 23. At this time, the bean box body 11 is in a rotatable state, and the cover plate 12 is in a fixed clamping state. Then the user can drive the bean box body 11 to rotate relative to the cover plate 12, so as to realize the rotation of the blocking piece 13 to open or close the connection between the bean lowering hole 111 and the bean dropping hole 121, thereby realizing bean lowering or bean sealing. In addition, by using the positioning clamping structure designed in the bean box device 1, even under the influence of the vibration of coffee bean grinding, the blocking piece 13 can also be maintained at a reliable position to connect the bean lowering hole 111 and the bean dropping hole 121, ensuring reliable bean lowering.

[0063] In summary, the bean box device and the coffee machine having the same of the present invention have the following beneficial effects:

[0064] (i) By providing a positioning clamping structure, when the bean box body 11 is driven to rotate until the bean drop hole 111 is completely connected with the bean drop hole 121, the bean box body 11 and the cover plate 12 are positioned and clamped by the positioning clamping structure, thereby preventing the bean box body 11 from deviating and rotating, and ensuring stable and reliable bean drop.

[0065] (ii) Since a bean lowering hole 111 is provided at the center of the bottom of the bean box body 11, when the bean box body 11 rotates relative to the cover plate 12 around the center of the bean lowering hole 111, the blocking piece 13 can be driven to rotate to open or close the connection between the bean lowering hole 111 and the bean dropping hole 121, thereby realizing the bean dropping or bean sealing function, with a simple structure and low manufacturing cost; at the same time, since the bean box body 11 will not drive the coffee beans to move when rotating around the center of the bean lowering hole 111, it is not easy to cause the coffee beans to get stuck, and the reliability is high.

[0066] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above 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 utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
