[0072] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a bean box device for a bean grinding system 8, wherein the bean grinding system 8 is mainly used to grind coffee beans 9 into coffee powder, and the bean grinding system 8 has a bean inlet.

[0073] The bean box device comprises a bean box assembly 2, a base 1, and a support assembly 6 and a bean changing part 3 respectively arranged on the base 1. The bean box assembly 2 comprises a first bean box 21 and a second bean box 22, and the support assembly 6 comprises a first support 61 for supporting the first bean box 21 and a second support 69 for supporting the second bean box 22.

[0074] The first bracket 61 has a first bean outlet passage 611 connected to the first bean box 21 , and the coffee beans 9 in the first bean box 21 can be poured out through the first bean outlet passage 611 .

[0075] The second bracket 69 has a second bean outlet passage 681 connected to the second bean box 22 , and the coffee beans 9 in the second bean box 22 can be poured out through the second bean outlet passage 681 .

[0076] A third bean outlet channel 682 may be provided on one of the first bracket 61 and the second bracket 69 or on the base 1. The outlet of the third bean outlet channel 682 is opposite to the bean inlet of the bean grinding system 8. The coffee beans 9 can enter the bean grinding system 8 through the third bean outlet channel 682.

[0077] The bean changing component 3 has a switching channel, and the bean changing component 3 has a first state, a second state and a third state relative to the bracket.

[0078] like Figure 3 As shown, when the bean changing member 3 is in the first state, the bean changing member 3 closes the first bean outlet channel 611 and the second bean outlet channel 681, and at this time, the coffee beans 9 in the first bean box 21 and the coffee beans 9 in the second bean box 22 cannot be poured out.

[0079] like Figure 4 As shown, when the bean changing part 3 is in the second state, the switching channel connects the first bean outlet channel 611 and the third bean outlet channel 682, and the coffee beans 9 in the first bean box 21 can enter the third bean outlet channel 682 through the first bean outlet channel 611, and then enter the bean grinding system 8.

[0080] like Figure 5 As shown, when the bean changing part 3 is in the third state, the switching channel connects the second bean outlet channel 681 and the third bean outlet channel 682, and the coffee beans 9 in the second bean box 22 can enter the third bean outlet channel 682 through the second bean outlet channel 681, and then enter the bean grinding system 8.

[0081] The bean box device of this embodiment switches between the first state and the third state by the bean changing member 3, so that the two bean boxes can be closed at the same time to put beans, and the two bean boxes can be switched at will to put beans. In addition, since the third bean outlet channel 682 is provided, the volume of the third bean outlet channel 682 can be used to quantitatively transport coffee beans 9, thereby avoiding wasting too many coffee beans 9 and providing a good user experience.

[0082] like Figure 1 As shown, in some embodiments, the base 1 may include two parts: a fixing cover 10 and a connecting plate 11 .

[0083] The fixing cover 10 is located above the connecting plate 11, and the fixing cover 10 is buckled on the connecting plate 11. The first bracket 61 and the second bracket 69 can be fixed on the connecting plate 11.

[0084] The fixed cover 10 is provided with a first box hole (not shown in the figure) and a second box hole (not shown in the figure). The first bean box 21 is inserted into the first box hole to be fixed on the first bracket 61, and the second bean box 22 is inserted into the second box hole to be fixed on the second bracket 69. This structure facilitates the installation and removal of the two bean boxes.

[0085] like Figure 1 As shown, in some embodiments, the first bracket 61 may have a first limit buckle 66, a first positioning switch 631 and a first push rod 641, and the second bracket 69 may have a second limit buckle 65, a second positioning switch 632 and a second push rod 642.

[0086] When the first bean box 21 is placed on the first bracket 61, the first bean box 21 can pass through the first box hole to be stuck on the first limit buckle 66, and push the first top rod 641 to move downward to touch the first positioning switch 631; when the second bean box 22 is placed on the second bracket 69, the second bean box 22 can pass through the second box hole to be stuck on the second limit buckle 65, and push the second top rod 642 to move downward to touch the second positioning switch 632.

[0087] The first positioning switch 631 and the second positioning switch 632 provided on the bracket can be used to conveniently let the user know whether the two bean boxes are installed in place. As for the connection structure between the first limit buckle 66 and the second limit buckle 65 and the two bean boxes, no specific limitation is made.

[0088] like Figure 1 As shown, in some embodiments, the first bean box 21 includes a first box cover 211, a first box body 212, a first knob 213, a first fixing frame 214 and a first bean box switch 215. The first box body 212 is a barrel structure with both ends open, the first box cover 211 is used to cover the top open end of the first box body 212, and the first bean box switch 215 is used to cover the bottom open end of the first box body 212.

[0089] like Fig.14 As shown, the first bean box switch 215 is provided with at least two fan-shaped bean outlets 216 and a rotating column 217, the rotating column 217 is rotatably connected to the first bean box switch 215, the bottom of the rotating column 217 is connected to a fan-shaped plate (not shown in the figure), and the fan-shaped plate can be rotated by rotating the rotating column 217 to open or close the fan-shaped bean outlet 216.

[0090] The first knob 213 is connected to the top of the rotating column 217 through the first fixing frame 214, and the rotating column 217 can be driven to rotate by rotating the first knob 213. Before loading beans into the first box body 212, the first knob 213 can be rotated to close the fan-shaped bean outlet 313216, and then the coffee beans 9 can be loaded into the first box body 212, so as to prevent the coffee beans 9 from falling directly into the first bean outlet channel 611.

[0091] In some embodiments, the second bean box 22 includes a second box cover 221, a second box body 222, a second knob 223, a second fixing frame 224, and a second bean box switch 225. The assembly relationship between the second box cover 221, the second box body 222, the second knob 223, the second fixing frame 224, and the second bean box switch 225 is the same as the assembly relationship between the first box cover 211, the first box body 212, the first knob 213, the first fixing frame 214, and the first bean box switch 215, and will not be described in detail.

[0092] like Figure 1 , Figures 6 to 8 As shown, in some embodiments, the bean changing component 3 includes a bean changing box 31 and a bean changing switch 32.

[0093] The bean changing box 31 can be fixed on the connecting plate 11 of the base 1, and is provided with a bean changing chamber 310 and a first bean inlet 311, a second bean inlet 312 and a bean outlet 313 respectively connected to the bean changing chamber 310. The bean changing chamber 310 forms a switching channel of the bean changing member 3, wherein the first bean inlet 311 is opposite to the outlet of the first bean outlet channel 611, the second bean inlet 312 is opposite to the outlet of the second bean outlet channel 681, and the bean outlet 313 is opposite to the entrance of the third bean outlet channel 682.

[0094] Furthermore, a baffle portion is provided on the bean changing switch 32 , and the bean changing switch 32 is connected to the bean changing box 31 and can rotate relative to the bean changing box 31 , and has a first position, a second position and a third position relative to the bean changing box 31 .

[0095] like Figure 3 As shown, when the bean changing switch 32 is in the first position, the baffle portion on the bean changing switch 32 blocks the first bean inlet 311 and the second bean inlet 312. At this time, the coffee beans 9 in the first bean box 21 and the coffee beans 9 in the second bean box 22 cannot enter the bean changing chamber 310 through the corresponding bean inlets. At this time, the bean changing member 3 is in the first state.

[0096] like Figure 4 As shown, when the bean changing switch 32 is in the second position, the baffle portion on the bean changing switch 32 blocks the second bean outlet channel 681 and avoids the first bean outlet channel 611. At this time, the coffee beans 9 in the first bean box 21 enter the bean changing chamber 310 through the first bean outlet channel 611.

[0097] like Figure 5 As shown, when the bean changing switch 32 is in the third position, the baffle portion on the bean changing switch 32 blocks the first bean outlet channel 611 and avoids the second bean outlet channel 681. At this time, the coffee beans 9 in the second bean box 22 enter the bean changing chamber 310 through the second bean outlet channel 681. The structure of the bean changing member 3 can facilitate its switching between the first state, the second state and the third state.

[0098] The first position may be between the second position and the third position in the rotation direction of the bean changing switch 32. When the bean changing switch 32 is in the first position, it may be rotated clockwise to the second position, and may be rotated counterclockwise to the third position.

[0099] like Figure 6 As shown, in some embodiments, the bean changing chamber 310 may be connected to the top of the bean changing box 31, and the first bean inlet 311, the second bean inlet 312 and the bean outlet 313 may be respectively formed on the side wall of the bean changing box 31. The bottom of the bean changing chamber 310 is inclined, and the bean outlet 313 is located below the first bean inlet 311 and the second bean inlet 312. In this way, the coffee beans 9 entering the bean changing chamber 310 can be poured out through the bean outlet 313 under the action of gravity, avoiding blockage in the bean changing chamber 310.

[0100] In some embodiments, the bean changing switch 32 can be buckled on the bean changing box 31, and the bottom of the bean changing switch 32 can have a bean guiding cavity 326 and a skirt portion 327 and a notch portion 328 arranged around the bean guiding cavity 326. The entire skirt portion 327 can form a baffle portion of the bean changing switch 32.

[0101] The bean guide cavity 326 on the bean changing switch 32 is opposite to the bean changing cavity 310 on the bean changing box 31, and the skirt portion 327 and the notch portion 328 on the bean changing switch 32 can be respectively extended into the bean changing cavity 310, and the skirt portion 327 is opposite to the cavity wall of the bean changing cavity 310, and the bean changing switch 32 can rotate relative to the bean changing box 31, so that its skirt portion 327 is opposite to the first bean inlet 311 or the second bean inlet 312, thereby blocking the first bean inlet 311 or the second bean inlet 312. For example, when the skirt portion 327 is opposite to the first bean inlet 311, the first bean inlet 311 is blocked, and when the notch portion 328 is opposite to the second bean inlet 312, the second bean inlet 312 is opened. The bean changing part 3 has a compact structure, which can reduce its occupied space.

[0102] like Figure 8 As shown, in some embodiments, the bottom of the bean guide chamber 326 can be set obliquely upward, and the higher side of the bottom of the bean guide chamber 326 is opposite to the notch portion 328. When the notch portion 328 of the bean changing switch 32 is opposite to the first bean inlet 311 or the second bean inlet 312, the coffee beans 9 in the two bean boxes can fall into the middle of the bean changing chamber 310 as much as possible under the restriction of the bottom of the bean guide chamber 326, thereby facilitating the loading of beans into the bean changing chamber 310.

[0103] like Figure 1 , Figures 6 to 8 As shown, in some embodiments, the bean box device further includes a driving motor 4, a switch assembly 5 and a trigger assembly.

[0104] Among them, the driving motor 4 is located at the top of the bean changing switch 32, the driving motor 4 can be fixed on the base 1, and the motor shaft of the driving motor 4 is connected to the bean changing switch 32, which is used to drive the bean changing switch 32 to rotate relative to the bean changing box 31, so that the bean changing switch 32 can switch back and forth between the first position, the second position and the third position.

[0105] Further, the switch assembly 5 includes a first switch 51 and a second switch 52 respectively connected to the drive motor 4, and the first switch 51 and the second switch 52 are respectively connected to the drive motor 4. When at least one of the first switch 51 and the second switch 52 is triggered, the drive motor 4 stops rotating.

[0106] The trigger unit assembly includes a first trigger unit, a second trigger unit and a third trigger unit which are respectively arranged on the bean changing switch 32.

[0107] When the bean changing switch 32 is rotated to the first position, the first triggering part can respectively trigger the first switch 51 and the second switch 52. When the bean changing part 3 is in the second position, the second triggering part triggers the first switch 51, and the third triggering part is separated from the second switch 52; when the bean changing part 3 is in the third position, the second triggering part is separated from the first switch 51, and the third triggering part triggers the second switch 52.

[0108] like Figure 7 As shown, in some embodiments, the top of the bean changing switch 32 has a connecting portion and a first annular rib plate 321 and a second annular rib plate 322 respectively arranged around the connecting portion, and the inner diameter of the second annular rib plate 322 is greater than the inner diameter of the first annular rib plate 321.

[0109] The connection part may be located in the middle of the top of the bean changing switch 32 for connection with the motor shaft of the driving motor 4, and the shape of the connection part is not specifically limited.

[0110] The top of the first annular rib plate 321 has a first high portion 323 and a second high portion 324 , and the top of the second annular rib plate 322 has a third high portion 325 and a fourth high portion 329 .

[0111] It should be noted that the two high-position parts on the top of the two annular ribs can be understood as relatively high parts in a certain area on the top of the two annular ribs.

[0112] In some embodiments, the first high portion 323 of the first annular rib plate 321 is opposite to the fourth high portion 329 of the second annular rib plate 322, and the first high portion 323 and the fourth high portion 329 together form a first triggering portion. That is, when the bean changing switch 32 is rotated to the first position, the first high portion 323 can trigger the first switch 51, and the second high portion triggers the second switch 52.

[0113] Furthermore, the second high portion 324 on the first annular rib plate 321 forms a second triggering portion, and the third high portion 325 on the second annular rib plate 322 forms a third triggering portion. That is, when the bean changing switch 32 is rotated to the first position, the first high portion 323 can trigger the first switch 51, and the second high portion 324 can trigger the second switch 52.

[0114] like Figure 1 He Ru Figure 7 As shown, when the driving motor 4 drives the bean changing switch 32 to rotate in the clockwise direction, the second high position part 324 triggers the first switch 51, and the driving motor 4 stops rotating at this time. The first bean inlet 311 is opened, and the second bean inlet 312 is closed. The coffee beans 9 in the first bean box 21 enter the bean changing chamber 310 of the bean changing box 31 from the first bean outlet channel 611 and the first bean inlet 311, and then enter from the bean outlet 313 and the third bean outlet channel 682, and enter the bean grinding system 8 for grinding; when the driving motor 4 is controlled to rotate in the counterclockwise direction again, the first high position part 323 on the bean changing switch 32 can trigger the first switch 51, and the second high position part triggers the second switch 52. At this time, the driving motor 4 stops rotating, and the first bean inlet 311 and the second bean inlet 312 are closed at the same time. At this time, the bean changing chamber 310 and the third bean outlet channel 682 form a channel for quantitative coffee beans 9.

[0115] When the driving motor 4 is controlled to continue to rotate in the counterclockwise direction, the second high-position part 324 on the bean changing switch 32 triggers the second switch 52. At this time, the driving motor 4 stops rotating, the first bean inlet 311 is closed, and the second bean inlet 312 is opened. The coffee beans 9 in the second bean box 22 enter the bean changing chamber 310 of the bean changing box 31 from the second bean outlet channel 681 and the second bean inlet 312, and then enter from the bean outlet 313 and the third bean outlet channel 682 to enter the bean grinding system 8 for grinding; when the driving motor 4 is controlled to rotate in the clockwise direction, the first high-position part 323 on the bean changing switch 32 can trigger the first switch 51, and the second high-position part triggers the second switch 52. At this time, the driving motor 4 stops rotating, the first bean inlet 311 and the second bean inlet 312 are closed at the same time, and the bean changing chamber 310 and the third bean outlet channel 682 form a channel for quantitative coffee beans 9.

[0116] In some embodiments, the third bean outlet passage 682 can be formed in one of the first bracket 61 and the second bracket 69. Integrating the third bean outlet passage 682 in one of the two brackets can facilitate processing and assembly. This application only takes the example that the third bean outlet passage 682 is formed on the second bracket 69 for explanation.

[0117] The third bean outlet passage 682 is provided on the second bracket 69, and the third bean outlet passage 682 may be located below the second bean outlet passage 681. The entrance of the second bean outlet passage 681 is located at the top of the first bracket 61, and the exit of the third bean outlet passage 682 is located at the bottom of the second bracket 69.

[0118] Furthermore, the outlet of the second bean outlet channel 681 and the inlet of the third bean outlet channel 682 can be located at the side of the first bracket 61, respectively, and the entire second bean outlet channel 681 is inclined along the lower left of the first bracket 61, and the entire third bean outlet channel 682 is inclined along the lower right of the first bracket 61. The design of the second bean outlet channel 681 and the third bean outlet channel 682 is not only convenient for bean discharge, but also can reduce the need for the second bracket to discharge beans.

[0119] 69 occupied spaces.

[0120] like Fig.10 and Fig.11 As shown, in some embodiments, the second bracket 69 mainly includes two parts: a bracket member 62 and a bean channel 68 .

[0121] The support member 62 can be used to fix the second bean box 22. The support member 62 has a central channel 620 running through the upper and lower ends thereof, and a first through hole 621 and a second through hole 622 respectively connected to the central channel 620. The first through hole 621 and the second through hole 622 are both located on the side wall of the support member 62, and the first through hole 621 is located above the second through hole 622.

[0122] The second bean outlet channel 681 and the third bean outlet channel 682 are respectively arranged on the bean channel 68, and the bean channel 68 is fixed in the central channel 620 of the support member 62. Moreover, the outlet of the second bean outlet channel 681 is opposite to the first through hole 621 on the support member 62, and the inlet of the third bean outlet channel 682 is opposite to the second through hole 622 on the support member 62.

[0123] The support member 62 of this embodiment may be an integral structure with the bean channel 68 , or the two may be detachably connected, so as to facilitate the processing of the second bean outlet channel 681 and the third bean outlet channel 682 .

The adjustment bracket 7 is connected to the adjustment ring 80, so that the adjustment ring 80 can be driven to rotate by rotating the adjustment bracket 7, thereby adjusting the bean grinding system 8. Usually, the bean grinding system 8 is placed inside the coffee machine, and the first bean box 21 and the second bean box 22 are exposed. By mounting the adjustment bracket 7 on the second box body 222, the user can conveniently control the adjustment ring 80 on the bean grinding system 8 from the outside.

[0126] In some embodiments, the adjustment bracket 7 includes a first annular hoop 73, a second annular hoop 74 and a rib connecting the two annular hoop. The first annular hoop 73 can be used to be sleeved on the second bean box 22 or the second bracket 69. At least two grooves 72 are spaced apart on the first annular hoop 73.

[0127] The adjusting ring 80 is provided with a protruding block 801 opposite to the groove portion 72. When the first annular hoop 73 is sleeved on the second bean box 22, the protruding block 801 on the adjusting ring 80 is embedded in the groove portion 72 on the adjusting bracket 7, so that the adjusting bracket 7 drives the adjusting ring 80 to rotate synchronously.

[0128] In some embodiments, the first annular hoop 73 is provided with a paddle portion 71 protruding outward, and the user can push the paddle portion 71 to drive the adjustment bracket 7 to rotate relative to the second box body 222 .
