[0029] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0030] Embodiment 1: A coffee bean grinder for grinding coffee powder, see Figures 1 to 5, including a housing 29, a scale adjustment component provided on the top of the housing 29, a bean grinding component provided inside the housing 29, a power cord 40 and a control board 31 below the inside of the housing 29, a powder discharging component provided on the front of the outside of the housing 29, a powder receiving component provided on the front of the outside of the housing 29, and a power switch 32 provided on the outer side of the housing 29. A motor 28 for grinding beans and a grinding cutter head 15 are provided on the bean grinding component inside the housing 29. The position of the power switch 32 corresponds to the position of the control board 31, and it is connected to the control board 31 for controlling power on and off.

[0031] Specifically, refer to Figure 1 , the scale adjustment component is composed of an upper cover 4, a middle cover 5, a bearing 7, and an upper tool rest 8; wherein, the upper cover 4 is threadedly connected to the middle cover 5, the bearing 7 is installed on the upper tool rest 8, and the upper cover 4 presses on the bearing 7. By rotating the upper cover 4, the up and down movement of the upper cover drives the up and down movement of the upper tool rest 8; the upper cover 4 presses on the bearing 7, and the bearing 7 significantly reduces the force required to rotate the upper cover 4 to achieve the purpose of saving effort. At the same time, both the upper small circle and the lower large circle of the upper cover 4 can be used for adjustment, providing two different position adjustment methods for the user to choose from. Moreover, the inner slope shape and the bottom large plane shape of the upper cover can effectively prevent the ground coffee beans from jumping out of the upper cover, realizing the anti-jumping function.

[0032] Furthermore, refer to Figure 2 , the scale zero adjustment structure is composed of a scale sticker 3, an upper cover 4, and a middle cover 5; wherein the scale sticker 3 is pasted on the upper cover 4, and the upper cover 4 is threadedly connected to the middle cover 5; when installing and adjusting to zero, the upper cover 4 is rotated downward until it just touches the zero position and then stops. Align the "0" scale position on the scale sticker 3 with the scale indicator in front of the middle cover 5, and then paste it on the upper cover 4; when the zero position is inaccurate after disassembling or replacing the cutter head, first unscrew the upper cover 4 from the middle cover 5, then use a thin rod to evenly push out the scale sticker 3 through the three through holes 45 behind the upper cover, then install the upper cover 4 back on the middle cover 5, rotate the upper cover 4 downward again until it just touches the zero position and stops, align the "0" scale position on the scale sticker 3 with the scale indicator in front of the middle cover 5, and then paste it on the upper cover 4. In this way, zero adjustment only requires pushing out the scale sticker 3 and pasting it again, simplifying the complex process.

[0033] It should be noted that refer to Figure 3, The anti-abrasion and anti-flying powder structure consists of a cavity 19, a powder outlet 22, a baffle 23, an inner powder tube 21, an outer powder tube 20, a magnet a 26, a copper needle 25, a screw e 24, and a plasma generator 30. During installation, the copper needle 25 and the magnet a 26 are respectively installed on the powder outlet 22 and the inner powder tube 21. The wire of the plasma generator 30 is divided into two segments and connected to the copper needle 25 installed on the powder outlet 22 and the inner powder tube 21. The wire of the plasma generator 30 with an emission needle is installed in two holes of the inner powder tube 21. Then, the inner powder tube 21 is installed in the outer powder tube 20, the baffle 23 is inserted on the powder outlet 22, and the powder outlet 22 is installed on the cavity 19 with the screw e 24. Then, the inner and outer powder tube assembly and the powder outlet 22 can be magnetically attracted and installed together through the magnet a 26. The magnetic attraction structure design enables the powder tube to be quickly disassembled and reinstalled.

[0034] When starting up and powering on for grinding, the powder passes through the outlet on the cavity 19. There are two thin bars at the outlet (these thin bars can be replaced by installing thin sheets of the same shape), which can disperse the powder and prevent the powder from caking. The powder passes through the powder outlet 22, and the baffle 23 is installed on the powder outlet 22. The baffle 23 can gather the extruded powder together and guide it to form a good powder outlet track. When the powder passes through the inner powder tube 21, the emission needle of the plasma generator 30 installed on the inner powder tube 21 generates positive and negative ions inside the powder tube. The neutralization of positive and negative ions can effectively eliminate the static electricity carried by the ground powder, so that the powder does not fly randomly and does not adsorb on the inner wall of the powder tube. Such a triple anti-flying powder structure design makes the powder in a smooth state without flying powder at this time. At the same time, after the powder is discharged, the baffle 23 can be toggled on the outside to eject the powder remaining at the powder outlet 22, ensuring that there is no or very little residual powder inside, giving the user a good powder outlet effect.

[0035] It should be noted that, referring to Figure 4 , The powder receiving and positioning structure consists of a bottom plate 38, a pressing piece 41, a screw h 42, a magnet b 43, and a cup 44; a magnet b 43 is installed at the bottom of the cup 44, a magnet b 43 is installed in the bottom groove of the bottom plate 38, and the pressing piece 41 is locked on the bottom plate 38 with the screw h 42, and the pressing piece 41 presses the magnet b 43 installed at the bottom of the bottom plate 38;

[0036] During use, the cup 44 is placed directly above the bottom plate 38 and can be automatically positioned at the magnet installation position on the bottom plate through magnetic attraction. At this time, if the user feels that the position is incorrect or wants to adjust the position, the screw h 42 can be loosened, and the magnet b 43 in the bottom limit groove of the bottom plate 38 can be moved to the corresponding position, and then the screw h 42 can be locked for positioning. In this way, the magnetic attraction position can be changed, which is convenient for the user to adjust.

[0037] It is worth introducing that, referring to Figure 5 as shown, which shows the basic structure of the present utility model. Referring to Figure 1, the scale adjustment component is installed on the cavity 19, the upper tool rest 8 is installed at three limits inside the cavity 19 and contacts the spring a9, and the cavity 19 is installed on the machine housing 29;

[0038] Refer to Figure 3 , the inner powder tube 21 is installed on the cavity 19, the outer powder tube 20 is installed on the inner powder tube 21, the plasma generator 30 is installed under the motor 28, the control board 31 is installed on the bottom plate 38, the switch 32, the potentiometer 33, and the knob 34 are installed on the outside of the machine housing 29, the bottom plate 38 is installed at the bottom of the machine housing 29, and for the installation of the powder receiving positioning structure, refer to Figure 4 .

[0039] Inside the cavity 19, cutter heads 15 are installed in the upper tool rest 8 and the lower tool rest 17. A pin 27 is installed on the lower tool rest 17, and the lower tool rest 17 is positioned and installed on the shaft of the motor 28 through the pin 27.

[0040] During use, coffee beans fall from the top press 2. The rotatable upper cover 4 can be adjusted for the scale to control the fineness of the coffee powder. The coffee powder exits from the outlet of the cavity 19. The anti-flying powder structure installed at the outlet adjusts the powder discharging state to prevent powder from flying and ensure smooth powder discharging. The coffee powder falls into the cup 44 through the outer powder tube 20.

[0041] In addition, the components designed in the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods.
