[0035] The embodiment of the utility model provides a bean grinding device, which mainly includes a bean grinding support 1, a bean grinding assembly 2 and a host control board 8 for driving the bean grinding assembly 2 to start and stop.

[0036] The bean grinding assembly 2 is arranged on the bean grinding support 1, and the bean grinding assembly 2 is used to grind coffee beans into coffee powder. The bean grinding assembly 2 mainly includes a bean grinding motor and a bean grinding box. The bean grinding box is used to place coffee beans. A bean grinding knife assembly is arranged in the bean grinding box. The bean grinding motor is connected to the bean grinding knife assembly to drive the bean grinding knife assembly to rotate to grind the coffee beans into coffee powder. The host control board 8 is electrically connected to the bean grinding motor of the bean grinding assembly 2, and is mainly used to control the start and stop of the bean grinding motor.

[0037] like Figures 1 to 4 As shown, the bean grinding device of this embodiment further includes a powder outlet chamber assembly 3, a funnel support 4 and a weighing assembly 6.

[0038] The powder outlet chamber assembly 3 is fixed on the bean grinding bracket 1 , and the powder outlet chamber assembly 3 is connected to the powder outlet of the bean grinding assembly 2 through the powder outlet channel 7 , and the coffee powder ground by the bean grinding assembly 2 enters the powder outlet chamber assembly 3 through the powder outlet channel 7 .

[0039] The funnel support 4 is arranged in the powder outlet chamber assembly 3 and is used to receive the funnel assembly 5. When the funnel assembly 5 is placed on the funnel support 4, it is opposite to the outlet of the powder outlet channel 7, and the ground coffee powder just falls into the funnel assembly 5.

[0040] A through hole 30 is formed on the side wall of the powder discharge chamber assembly 3 , and a supporting portion 40 is formed on the funnel support 4 and extends through the through hole 30 to the outside of the powder discharge chamber assembly 3 .

[0041] The weighing assembly 6 is located outside the powder discharge chamber assembly 3. The weighing assembly 6 mainly includes a weighing detection component and a weighing bracket 65. The first end of the weighing bracket 65 is fixed on the bean grinding bracket 1, and the second end is suspended in the air. The weighing detection component is respectively connected to the second end of the weighing bracket 65 and the support portion 40 on the funnel bracket 4. The weighing bracket 65 is mainly used to detect whether the weight of the funnel bracket 4 as a whole has changed.

[0042] The weighing detection component of this embodiment is electrically connected to the host control board 8. When the funnel assembly 5 is placed on the funnel bracket 4, the weighing detection component detects the weight of the funnel assembly 5 on the funnel bracket 4 and can feed back the detected weight to the host control board 8, and the host control board 8 can start the bean grinding assembly 2 according to the fed-back weight signal.

[0043] Correspondingly, as the bean grinding assembly 2 is continuously ground, the amount of coffee powder falling into the funnel assembly 5 is continuously increasing, thereby causing the weight of the funnel assembly 5 to continuously increase. The increased weight is the amount of coffee powder. When the weighing detection component feeds back that the accumulated ground powder weight is equal to the powder output amount set by the system, it is fed back to the host control board 8. The host control board 8 can close the bean grinding assembly 2 according to the fed-back powder output weight.

[0044] Specifically, assuming that the weight of the funnel assembly 5 is 300 grams, the weight parameter can be set or input in advance on the host control board 8, such as 300 grams. When the funnel assembly 5 is placed on the funnel bracket 4, the weighing detection component detects the weight of 300 grams and feeds back to the host control board 8. The host control board 8 determines that the funnel assembly 5 has been placed on the funnel bracket 4 based on the fed-back weight, and then automatically starts the bean grinding assembly 2 to start grinding coffee powder. Assuming that the set powder output is 100 grams, when the weighing detection component detects that the weight of the ground coffee powder reaches 100 grams, it will be fed back to the host control board 8, and the host control board 8 will then close the bean grinding assembly 2 based on the fed-back powder output.

[0045] Therefore, the bean grinding device of this embodiment is provided with a weighing component 6 to identify whether the funnel component 5 is placed on the funnel support 4 to control the start and stop of the bean grinding component 2. In this way, there is no need to provide a corresponding trigger switch, thereby improving the intelligence of the bean grinding device.

[0046] like Figure 1 As shown, in some embodiments, the weighing detection component includes a weighing balance block 60 , a weighing sensor sheet 61 and an electronic scale control board 62 .

[0047] The weighing balance block 60 is in the shape of an elongated strip, a first end of the weighing balance block 60 is connected to a second end of a weighing bracket 65 , and a second end of the weighing balance block 60 is connected to a supporting portion 40 on the funnel bracket 4 .

[0048] The weighing sensor sheet 61 is fixed at the middle of the weighing balance block 60 and is used to detect slight deformation of the weighing balance block 60 .

[0049] The electronic scale control board 62 is fixed on the outer peripheral wall of the powder discharge chamber assembly 3, and is electrically connected to the weighing sensor sheet 61 and the host control board 8 respectively. The electronic scale control board 62 can calculate the weight of the funnel assembly 5 placed on the funnel bracket 4 according to the deformation detected by the weighing sensor sheet 61, and feed back the detected weight signal to the host control board 8. The specific working principle of the weighing detection component belongs to the prior art and will not be described in detail. The weighing detection component of this embodiment has a simple structure and occupies a small space.

[0050] In some embodiments, the weighing weight 60 is connected to the support portion 40 on the funnel bracket 4 by a first bolt 63, and the weighing weight 60 is connected to the second end of the weighing bracket 65 by a second bolt 64. This structure facilitates the installation and removal of the weighing weight 60 and is easy to maintain.

[0051] The structural shape of the weighing bracket 65 of this embodiment is not specifically limited. Figure 5 As shown, in some embodiments, preferably, the weighing bracket 65 includes a first rib plate portion 651 and a second rib 652 connected to each other.

[0052] The first rib plate portion 651 and the second rib 652 are both in the shape of long strips. The first rib plate portion 651 is opposite to the bottom wall of the powder outlet chamber assembly 3, and the second rib 652 is opposite to the side wall of the powder outlet chamber assembly 3. The free end of the first rib plate portion 651 forms the first end of the weighing bracket 65 fixed to the bean grinding bracket 1, and the free end of the second rib 652 forms the second end of the weighing bracket 65 to be connected to the weighing balance block 60. The weighing bracket 65 has a simple structure and occupies a small space, which can save the internal space of the bean grinding bracket 1.

[0053] like Figure 1 As shown, in some embodiments, the side wall of the powder discharge chamber assembly 3 opposite to the through opening 30 is open.

[0054] Furthermore, the bean grinding bracket 1 is a box structure as a whole, and a shell opening opposite to the open side of the powder discharge chamber assembly 3 is provided on the side wall of the bean grinding bracket 1. The powder discharge chamber assembly 3 is fixed on the side wall of the bean grinding bracket 1, and the open end of the powder discharge chamber assembly 3 is opposite to the shell opening on the bean grinding bracket 1. The user can pass the funnel assembly 5 through the shell opening on the grinder bracket 1 and place it on the funnel bracket 4 in the powder discharge chamber assembly 3.

[0055] like Figure 2 As shown, in some embodiments, the bean grinding device further includes a powder outlet chamber fixing bracket 10 and a connecting bracket 11.

[0056] The overall shape of the powder outlet chamber fixing bracket 10 is adapted to the outer shape of the powder outlet chamber assembly 3 , and the powder outlet chamber fixing bracket 10 can be connected to the inner wall of the bean grinding bracket 1 to place the powder outlet chamber assembly 3 against the inner wall of the bean grinding bracket 1 .

[0057] The connecting bracket 11 is also fixed on the inner wall of the bean grinding bracket 1, but is located below the powder discharge chamber assembly 3 to abut against the bottom of the powder discharge chamber assembly 3, thereby supporting the powder discharge chamber assembly 3. The powder discharge chamber fixing bracket 10 and the connecting bracket 11 cooperate with each other to fix the powder discharge chamber assembly 3 on the inner wall of the bean grinding bracket 1.

[0058] Preferably, the first end of the weighing bracket 65 of this embodiment is connected to the connecting bracket 11 to fix the entire weighing bracket 65 .

[0059] like Figure 6 As shown, in some embodiments, the connecting bracket 11 for supporting the powder discharge chamber assembly 3 is a Z-shaped plate, which mainly includes a first panel 111, a second panel 112 and a third panel 113, and the second panel 112 is located between the first panel 111 and the third panel 113.

[0060] The first panel 111 is attached to and fixed on the inner wall of the bean grinding bracket 1, and the edge of the third panel 113 is in contact with the bottom of the powder discharge chamber assembly 3 to support the powder discharge chamber assembly 3. The first end of the weighing bracket 65 can be directly connected to the third panel 113.

[0061] like Figure 1 and Figure 4 As shown, in some embodiments, the bean grinding device further includes a reset button 9 electrically connected to the host control board 8.

[0062] Preferably, the host control panel 8 of this embodiment may have a weight memory function. Specifically, a preset weight parameter (such as 300 grams) may be input into the host control panel 8. When the weight of the hopper assembly 5 reaches the preset weight, the host control panel 8 can start the bean grinding assembly 2 according to the weight fed back by the weighing detection component. When a hopper assembly 5 of other weights is placed, the host control panel 8 will not control the bean grinding assembly 2. In this embodiment, a reset button 9 is set. By pressing the reset button 9, the weight parameter preset in the host control panel 8 can be cleared. Then, a hopper assembly of other weights is placed. The weighing detection component automatically detects the weight of the new hopper, and the host control panel 8 memorizes the weight of the new hopper. After the weight of the new hopper is detected and memorized, the new hopper is automatically identified. The host control panel 8 can start the bean grinding assembly 2 again, so that the bean grinding device can adapt to hopper assemblies 5 of different weights.

[0063] An embodiment of the utility model further provides a coffee machine, which comprises a bean grinding device as described in any one of the above embodiments.
