[0050] The "first" and "second" mentioned in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0051] On the one hand, if Figure 1 and Figure 2 As shown, a bean box component in one embodiment of the utility model includes:

[0052] The box shell 1 is provided with a receiving cavity 101 and a material drop hole 102 arranged at the bottom of the receiving cavity 101;

[0053] A box cover 2 is arranged on the top of the box shell 1;

[0054] The material blocking seat 11 is arranged in the accommodating cavity 101;

[0055] The adjusting component 61 includes a knob unit 62 arranged on the material blocking seat 11, and a connecting unit 63 connected to the knob unit 62. The connecting unit 63 is provided with a gear card 623 protruding from the bottom of the box shell 1. The adjusting component 61 rotates the knob unit 62 to drive the gear card 623 to rotate, thereby outputting an adjusting torque for adjusting the size of the grinding gap of the grinding component.

[0056] The bean box component sets the adjustment component 61 on the box shell 1, which only occupies part of the space in the accommodating cavity 101. By rotating the knob unit 62 and driving the gear card 623 to rotate, an adjustment torque for adjusting the size of the grinding gap of the grinding component is output, thereby reducing the overall volume of the grinding coffee machine and having a wide range of application scenarios.

[0057] like Figure 3 and Figure 4 As shown, in one embodiment, the connection unit 63 includes a connecting shaft 631 connected to the hub of the knob unit 62, an adjustment connection plate 632 connected to the connecting shaft 631, and a connection spring 633 sleeved on the connecting shaft 631. In this way, the connection spring 633 presses the material blocking seat 11, so that the adjustment connection plate 632 tends to move away from the material blocking seat 11.

[0058] In one embodiment, the knob unit 62 includes a knob outer shell 621 and a knob inner shell 622, a gear position card 623, and a gear position compression spring 624; the material stopper 11 is provided with a mounting cavity 103, and the mounting cavity 103 is provided with a gear position tooth groove including a plurality of tooth groove positions; the knob outer shell 621 is fixedly connected to the knob inner shell 622 and the lower part of the knob outer shell 621 is arranged in the mounting cavity 103; the knob inner shell 622 is provided with a connecting shaft portion connected to the hub of the connecting shaft 631, and a pressing portion for pressing the gear position compression spring 624; the gear position card 623 is provided with a top portion for pressing the gear position compression spring 624 and a fixed tooth portion for clamping the gear position tooth groove; the gear position compression spring 624 presses the gear position card 623, so that the fixed tooth portion is placed on the tooth groove position. Specifically, the bottom of the material stopper 11 is provided with a sleeve cylinder adapted to fit the connecting spring 633, and the connecting shaft 631 passes through the sleeve cylinder and is connected to the knob unit 62. In this way, by rotating the knob housing 621, the gear compression spring 624 is compressed, and the fixed tooth portion of the gear card 623 can move to the adjacent tooth groove position, so that the gear card 623 is limited to different rotation angles, achieving the effect of limiting the adjustment position.

[0059] like Figure 2 and Figure 5 , Figure 6As shown, in one embodiment, it also includes a switch door assembly 3 arranged below the box shell 1, and the switch door assembly 3 is used to switch the opening and closing state of the drop hole 102; the switch door assembly 3 includes at least two box door units 31 spaced along the central circumference of the box shell 1, and the box door unit 31 includes a box door member 32, and the box door member 32 is provided with a rotating portion 321, a material blocking portion 322, and a positioning portion 323, and the rotating portion 321 is rotatably connected to the bottom of the box shell 1. Since the existing coffee bean box device usually switches the opening and closing state of the drop hole 102 by staggering or aligning the holes, the drop hole 102 needs to block half of the cross-sectional area of ​​the corresponding through hole when it is opened, and the drop speed is slow and the efficiency is low, which leads to the problem that the coffee beans are easily stuck when they drop. In this way, by pressing the positioning portion 323, the material blocking portion 322 moves closer to the center of the box shell 1 with the rotating portion 321 as the rotation center, thereby switching the opening and closing state of the drop hole 102.

[0060] In one embodiment, the door assembly 3 includes three door units 31, the door units 31 also include a tension spring 33, and the door member 32 also includes a connecting portion 324 disposed between the rotating portion 321 and the material blocking portion 322; one end of the tension spring 33 is connected to the bottom of the box shell 1, and the other end is connected to the connecting portion 324. In this way, when the bean box components are disassembled and used alone, the drop hole 102 is automatically closed by the elastic tension of the tension spring 33 to prevent coffee beans from falling from the drop hole 102.

[0061] like Figure 2 and Figure 7 As shown, in one embodiment, the box cover 2 is mounted on the box shell 1 through a positioning structure 4, and the positioning structure 4 is used to limit the box cover 2 to rotate relative to the box shell 1 along its circumference. Specifically, the positioning structure 4 includes a positioning flange 41 arranged at the bottom of the box cover 2, a limiting protrusion 42 arranged on the positioning flange 41, and an upper shell edge 43 arranged at the top of the box shell 1; the positioning flange 41 is adapted to the upper shell edge 43, and the upper shell edge 43 is provided with a limiting groove 44 adapted to the limiting protrusion 42. In this way, the box cover 2 is mounted on the box shell 1 using the positioning structure 4, and the box cover 2 is limited to be unable to rotate on the box shell 1 and can only move along the central axis of the box shell 1.

[0062] On the other hand, Figure 6 and Figure 7 As shown, a coffee bean grinding machine in an embodiment of the utility model comprises a mounting shell 5 and a bean box component 6; a mounting flange 12 is provided at the bottom of the box shell 1, and a mounting groove 51 adapted to the mounting flange 12 is provided in the mounting shell 5. In this way, the mounting flange 12 is inserted into the mounting groove 51 to achieve the positioning of the bean box component 6 on the mounting shell 5.

[0063] In one embodiment, the positioning portion 323 is arranged at one end of the box door 32 away from the center of the box shell 1, and is provided with a positioning recess 325; the mounting shell 5 is provided with a positioning groove 52 adapted to the positioning portion 323, and a positioning convex arc 53 adapted to the positioning recess 325 is provided in the positioning groove 52. Specifically, the positioning portion 323 protrudes from the outer shell surface of the box shell 1. In this way, the positioning groove 52 is used to align the positioning portion 323, which plays a role of secondary guiding and positioning; at the same time, when the bean box component 6 is installed on the mounting shell 5, the positioning convex arc 53 is made to touch the positioning recess 325 by rotating the bean box component 6 to achieve the positioning of the box door 32, so that the blanking hole 102 is in an open state.

[0064] In one embodiment, a detection structure 7 is further included; the detection structure 7 includes a detection flange 71 disposed on the outer side of the box shell 1, and a detection unit 72 disposed on the mounting shell 5; the detection unit 72 includes a switch seat 721, a pressure rod 722, a spring member 723, and a detection switch 724 disposed on the switch seat 721; the switch seat 721 is provided with a mounting hole for mounting the spring member 723; the pressure rod 722 is provided with a fitting portion for fitting the spring member 723, a contact portion for supporting the detection flange 71, and a detection portion adapted to the detection point of the detection switch 724; the spring member 723 fits on the fitting portion and contacts the switch seat 721, pressing the pressure rod 722 close to the detection flange 71. In this way, when the bean box component 6 is placed on the mounting shell 5, the detection flange 71 presses the contact portion of the pressure rod 722, the spring member 723 is compressed, the detection portion contacts the detection point of the detection switch 724, and the detection switch 724 sends an electrical signal to the control board.

[0065] In one embodiment, the bean grinding component 8 is further included, and the bean box component 6 also includes an adjustment component 61; the bean grinding component 8 includes a grinding component 81 and a gap adjustment component 82, the grinding component 81 includes an inner grinding unit 811 provided with an inner grinding wheel 813 and an outer grinding unit 812 provided with an outer grinding wheel 814, and a bean grinding gap is formed between the outer grinding wheel 814 and the inner grinding wheel 813; the gap adjustment component 82 includes a first threaded barrel 821 and a second threaded barrel 822 adapted to each other, and the outer grinding unit 812 is mounted on the second threaded barrel 822; the top of the first threaded barrel 821 is provided with a connection groove adapted to the connection unit 63. Specifically, the installation housing 5 is provided with a placement cavity for placing the bean grinding component 8. In this way, by rotating the knob unit 62 to rotate the connection unit 63, the first threaded barrel 821 is driven to rotate, so that the outer grinding unit 812 on the second threaded barrel 822 moves up and down, and then the size of the bean grinding gap between the outer grinding wheel 814 and the inner grinding wheel 813 is adjusted.

[0066] In one embodiment, the compressible dimension of the connection spring 633 is greater than or equal to the depth dimension of the connection groove. Specifically, the notch of the connection groove is provided with a guide opening. In this way, the plate surface of the adjustment connection plate 632 is ensured to contact the bottom of the connection groove, and a large gap between the plate side of the adjustment connection plate 632 and the connection groove is avoided, which affects the adjustment accuracy.
