[0023] Please refer to the attached Figure 1 and the attached Figure 2 The coffee grinder machine is shown in the whole and split structure, including a lid 10, a motor part 20, a grinding tool 30 and a powder bin cup 40, wherein the lid 10 is covered on the motor part 20, the motor part 20 drives the grinding tool 30, and the powder bin cup 40 is screwed below the grinding tool 30. The main function is to catch the coffee powder in the grinding tool 30. The powder bin cup 40 is generally made of transparent material, which is convenient for observing the powder falling progress and the grinding effect. The best is made of high-silicon glass, which is transparent, impurity-free and has no odor.

[0024] The upper part of the motor part 20 is provided with a weighing scale part 60, which is connected between the motor part 20 and the lid 10 by means of movable connection. The motor part 20 and the grinding tool 30 are assembled together by means of movable connection, and the connecting parts of the two are provided with a locking structure 50.

[0025] Please refer to the attached Figure 3 and the attached Figure 4 The upper part of the motor part 20 is provided with a weighing scale part 60, which is connected between the motor part 20 and the lid 10 by means of movable connection. The weighing scale part 60 is used to weigh the coffee beans to be ground. If it is other coffee grinder, a food scale electronic scale is needed to weigh the coffee beans, and then the coffee beans are put into the coffee grinder for grinding. In this technical solution, an activity dismounting and mounting component, the weighing scale part 60, is directly added to weigh the coffee beans.

[0026] The weighing scale part 60 includes a shell 61, a top bin 62, a display screen 63, a control chip and electronic components (not shown), and a lower bin 64. The control chip and electronic components are built in the middle part of the shell 61, which divides the inside of the shell 61 into the space of the top bin 62 and the space of the lower bin 64. A bean outlet 65 is arranged between the two spaces, and a toggle valve 66 is arranged at the bean outlet 65. A display screen 63 is arranged in the top bin 62, which is electrically connected with the control chip and electronic components.

[0027] The weighing scale part 60 needs to complete the process of weighing and falling beans. First, the toggle valve 66 blocks the bean outlet 65, and the coffee beans are poured in. The top bin 62 constitutes a container for containing and weighing the coffee beans, and the display screen 63 is used to display the real-time weight at this time. When the target weight is reached, the toggle valve 66 is toggled to open the bean outlet 65, so that the weighed coffee beans fall down into the grinding tool 30 to complete the grinding.

[0028] The top bin 62 is divided into two parts, one part is occupied by the display screen 63 and the other part is the bin body part for accommodating coffee beans. The bottom of the top bin 62 is a conical bottom surface 621 suitable for material falling. At the lowest position, the bottom bean outlet 65 is connected. The bottom bean outlet 65 is provided with a push valve 66, which includes a valve piece 661 and a push piece 662. The valve piece 661 is blocked at the bottom bean outlet 65, and the push piece 662 drives the valve piece 661 to rotate to switch between the open and closed states of the bottom bean outlet 65.

[0029] Above the grinding tool 30 is the motor part 20. Some similar products integrate the motor and the grinding tool into a whole part that cannot be disassembled. The whole part has a hole for coffee beans to fall into the grinding disc. However, in the technical solution, the grinding tool 30 and the motor part 20 are relatively detachable. The motor part 20 drives the grinding tool 30 through a rotating shaft to drive the grinding disc to rotate and grind beans.

[0030] The outer surface of the motor part 20 is provided with a power-on button 21, a charging interface 22, and an indicator light 23.

[0031] The motor part 20 and the grinding tool 30 are assembled together through a movable connection. The connecting part of the two is provided with a locking structure 50. Because the motor part 20 and the grinding tool 30 are detachable, in order to ensure stable connection, vibration may occur during grinding, which may affect the stability and reliability of the connection. Therefore, a locking structure 50 is configured to ensure that the two are not easily separated, but are separated only when the user needs to do so.

[0032] The lid 10, the weight scale part 60, the motor part 20, and the grinding tool 30 are connected through a movable connection. They can be exchanged and assembled together. That is, the lid 10 can be connected and buckled to the weight scale part 60, and the weight scale part 60 can be connected and assembled to the top of the motor part 20, which originally has the lid 10. The lower part of the motor part 20 is assembled with the grinding tool 30. If the weight scale part 60 is not needed, the weight scale part 60 can be removed, and the lid 10 can be directly connected and buckled to the motor part 20.

[0033] The movable connection includes magnetic attraction or buckle type.

[0034] The motor part 20 and the grinding tool 30 are connected through a magnetic attraction movable connection. The connecting part is provided with a locking structure 50, which is a hook and slot structure. The hook is locked in the slot.
