[0072] As shown in Figure 1 and Figure 2 The present application provides a bean tank device for a bean grinding system 8, wherein the bean grinding system 8 is mainly used for grinding coffee beans 9 into coffee powder, and the bean grinding system 8 has a bean inlet.

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

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

[0075] The second support 69 has a second bean outlet passage 681 connected with the second bean tank 22, and the coffee beans 9 in the second bean tank 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 supports 61 and the second support 69 or on the base 1. The outlet of the third bean outlet channel 682 is opposite to the inlet of the grinding system 8, and coffee beans 9 can enter the 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 support.

[0078] like Figure 3 As shown, when the bean exchanger 3 is in the first state, the bean exchanger 3 closes the first bean outlet channel 611 and the second bean outlet channel 681. 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 unit 3 is in the second state, the switching channel connects the first bean outlet channel 611 and the third bean outlet channel 682. 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 grinding system 8.

[0080] like Figure 5 As shown, when the bean changer 3 is in the third state, the switching channel connects the second bean outlet channel 681 and the third bean outlet channel 682. 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 grinding system 8.

[0081] The bean hopper device in this embodiment can switch between the first and third states via the bean changing component 3, allowing for simultaneous bean dispensing from both bean hoppers and arbitrary switching between them. Furthermore, the inclusion of a third bean dispensing channel 682 enables the metered delivery of coffee beans 9, preventing excessive bean waste and resulting in a better 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 is fastened onto the connecting plate 11. The first bracket 61 and the second bracket 69 can be fixed onto the connecting plate 11.

[0084] The fixed cover 10 has two parts: a first box hole (not shown in the figure) and a second box hole (not shown in the figure). The first bean box 21 passes through the first box hole and is fixed to the first bracket 61, and the second bean box 22 passes through the second box hole and is fixed to the second bracket 69. This structure facilitates the installation and removal of the two bean boxes.

[0085] likeFigure 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 and be locked on the first limit buckle 66, and push the first push rod 641 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 and be locked on the second limit buckle 65, and push the second push rod 642 downward to touch the second positioning switch 632.

[0087] The first positioning switch 631 and the second positioning switch 632, which are mounted on the bracket, allow the user to easily determine whether the two bean boxes are installed correctly. The connection structure between the first limit buckle 66 and the second limit buckle 65 and the two bean boxes is not specifically defined.

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

[0089] like Figure 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). By rotating the rotating column 217, the fan-shaped plate can be rotated to open or close the fan-shaped bean outlets 216.

[0090] The first knob 213 is connected to the top of the rotating column 217 via the first fixing bracket 214. Rotating the first knob 213 can drive the rotating column 217 to rotate. Before loading coffee beans into the first housing 212, the first knob 213 can be rotated to close the fan-shaped bean outlet 313216, and then coffee beans 9 can be loaded into the first housing 212, thereby preventing coffee beans 9 from falling directly into the first bean outlet channel 611.

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

[0092] As shown in Figure 1 , Figures 6 to 8 , in some embodiments, the bean changing piece 3 comprises a bean changing tank 31 and a bean changing switch 32.

[0093] The bean changing tank 31 can be fixed on the connecting plate 11 of the base 1, and the bean changing tank 31 is provided with a bean changing cavity 310 and a first bean inlet 311, a second bean inlet 312 and a bean outlet 313 respectively communicating with the bean changing cavity 310. The bean changing cavity 310 forms a switching channel of the bean changing piece 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 inlet of the third bean outlet channel 682.

[0094] Further, the bean changing switch 32 is provided with a baffle part, the bean changing switch 32 is connected with the bean changing tank 31 and can rotate relative to the bean changing tank 31, and has a first position, a second position and a third position relative to the bean changing tank 31.

[0095] As shown in Figure 3 , when the bean changing switch 32 is in the first position, the baffle part 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 tank 21 and the coffee beans 9 in the second bean tank 22 cannot enter the bean changing cavity 310 through the corresponding bean inlets, at this time, the bean changing piece 3 is in the first state.

[0096] As shown in Figure 4 , when the bean changing switch 32 is in the second position, the baffle part 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 tank 21 enter the bean changing cavity 310 through the first bean outlet channel 611.

[0097] As shown in Figure 5 , when the bean changing switch 32 is in the third position, the baffle part 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 tank 22 enter the bean changing cavity 310 through the second bean outlet channel 681. The structure of the bean changing piece 3 can facilitate switching between the first state, the second state and the third state.

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

[0099] As shown in the drawings, Figure 6 In some embodiments, the bean switch cavity 310 can pass through to the top of the bean switch box 31, and the first bean inlet 311, the second bean inlet 312, and the bean outlet 313 can be formed on the side wall of the bean switch box 31. The bottom of the bean switch cavity 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 switch cavity 310 can be poured out through the bean outlet 313 under the action of gravity, avoiding clogging in the bean switch cavity 310.

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

[0101] The bean guide cavity 326 on the bean switch 32 is opposite to the bean switch cavity 310 on the bean switch box 31, and the skirt portion 327 and the notch portion 328 on the bean switch 32 can respectively extend into the bean switch cavity 310, and the skirt portion 327 is opposite to the cavity wall of the bean switch cavity 310. The bean switch 32 can be rotated relative to the bean switch box 31, so that the 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 structure of the bean switch 3 is compact, which can reduce the occupied space.

[0102] As shown in the drawings, Figure 8 In some embodiments, the bottom of the bean guide cavity 326 can be inclined upward, and the higher side of the bottom of the bean guide cavity 326 is opposite to the notch portion 328. When the notch portion 328 of the bean 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 as much as possible to the middle of the bean switch cavity 310 under the restriction of the bottom of the bean guide cavity 326, thereby facilitating the bean switch cavity 310 to drop the beans.

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

[0104] The driving motor 4 is located on the top of the bean switch 32, and the driving motor 4 can be fixed on the base 1. The motor shaft of the driving motor 4 is connected with the bean switch 32, and is used to drive the bean switch 32 to rotate relative to the bean box 31, so as to switch the bean switch 32 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 connected with the driving motor 4 respectively. When at least one of the first switch 51 and the second switch 52 is triggered, the driving motor 4 will stop rotating.

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

[0107] When the bean switch 32 rotates to the first position, the first trigger can trigger the first switch 51 and the second switch 52 respectively. When the bean piece 3 is in the second position, the second trigger triggers the first switch 51, and the third trigger is separated from the second switch 52. When the bean piece 3 is in the third position, the second trigger is separated from the first switch 51, and the third trigger triggers the second switch 52.

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

[0109] The connecting portion can be located at the middle position of the top of the bean switch 32, and is used to connect with the motor shaft of the driving motor 4. The shape of the connecting portion is not limited.

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

[0111] It should be noted that the two high positions of the top of the two annular rib plates can be understood as the positions with relatively high height in a certain area of the top of the two annular rib plates.

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

[0113] Furthermore, the second high-position portion 324 on the first annular rib 321 forms a second trigger portion, and the third high-position portion 325 on the second annular rib 322 forms a third trigger portion.

[0114] like Figure 1 He Ru Figure 7 As shown, when the drive motor 4 drives the bean change switch 32 to rotate clockwise, the second high position 324 triggers the first switch 51. At this time, the drive motor 4 stops rotating, 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 change chamber 310 of the bean change 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 to enter the grinding system 8 for grinding. When the drive motor 4 is controlled to rotate counterclockwise, the first high position 323 on the bean change switch 32 can trigger the first switch 51, and the second high position 323 triggers the second switch 52. At this time, the drive 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 change chamber 310 and the third bean outlet channel 682 form a channel for metering coffee beans 9.

[0115] When the drive motor 4 continues to rotate counterclockwise, the second high position 324 on the bean change switch 32 triggers the second switch 52. At this time, the drive 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 grinding system 8 for grinding. When the drive motor 4 rotates clockwise, the first high position 323 on the bean change switch 32 can trigger the first switch 51, and the second high position 323 triggers the second switch 52. At this time, the drive 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 metering coffee beans 9.

[0116] In some embodiments, the third bean outlet channel 682 may be formed on one of the first brackets 61 and the second bracket 69. Integrating the third bean outlet channel 682 into one of the two brackets facilitates processing and assembly. This application only illustrates the example of the third bean outlet channel 682 being formed on the second bracket 69.

[0117] The third bean outlet channel 682 is located on the second support 69, and the third bean outlet channel 682 can be located below the second bean outlet channel 681. The inlet of the second bean outlet channel 681 is located at the top of the first support 61, and the outlet of the third bean outlet channel 682 is located at the bottom of the second support 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 on the side of the first support 61, respectively. The entire second bean outlet channel 681 is inclined to the lower left of the first support 61, and the entire third bean outlet channel 682 is inclined to the lower right of the first support 61. The design of the second and third bean outlet channels 681 not only facilitates bean feeding but also reduces their impact on the second support.

[0119] It takes up 69 units of space.

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

[0121] The bracket 62 can be used to fix the second bean box 22. The bracket 62 has a central channel 620 that passes through its upper and lower ends and a first through hole 621 and a second through hole 622 that are 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 bracket 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 provided on the bean channel 68, which 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] In this embodiment, the support member 62 can be integrated with the bean channel 68, or the two can be detachably connected, thereby facilitating the processing of the second bean outlet channel 681 and the third bean outlet channel 682.

[0124] like Figure 2 , Figure 12 and Figure 13As shown, in some embodiments, the grinding system 8 further has an adjusting ring 80, and rotating the adjusting ring 80 can adjust the fineness of the coffee powder ground by the grinding system 8.

[0125] The bean bin device further comprises an adjusting support 7, which can be sleeved on the second bin 222 or the second support 69 and can rotate relative to the second bin 222, and the adjusting support 7 is connected with the adjusting ring 80, so that the adjusting ring 80 can be rotated by rotating the adjusting support 7, and the grinding system 8 is adjusted. Generally, the grinding system 8 is arranged inside the coffee machine, and the first bean bin 21 and the second bean bin 22 are exposed. By sleeving the adjusting support 7 on the second bin 222, the user can conveniently control the adjusting ring 80 on the grinding system 8 outside.

[0126] In some embodiments, the adjusting support 7 comprises a first annular hoop 73, a second annular hoop 74, and a rib connecting the two annular hoops. The first annular hoop 73 can be used to sleeve the second bean bin 22 or the second support 69, and the first annular hoop 73 is provided with at least two groove portions 72 at intervals.

[0127] The adjusting ring 80 is provided with a protruding block 801 opposite to the groove portion 72. In the case that the first annular hoop 73 sleeves the second bean bin 22, the protruding block 801 on the adjusting ring 80 is embedded into the groove portion 72 on the adjusting support 7, so that the adjusting support 7 drives the adjusting ring 80 to rotate synchronously.

[0128] In some embodiments, the first annular hoop 73 is provided with an outwardly protruding dial plate portion 71, and the user can push the dial plate portion 71 to drive the adjusting support 7 to rotate relative to the second bin 222.
