DETAILED DESCRIPTION

[0022] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0023] Example 1: A new type of coffee grinder, see Figures 1 to 5 The bean grinder assembly includes a housing 21, a scale adjustment assembly provided at the front of the housing 21, a bean inlet assembly provided at the top of the housing 21, a bean grinding assembly provided inside the housing 21, a power cord 28 and a control board 25 assembly provided at the bottom of the housing 21, a powder discharge assembly provided at the bottom of the housing 21, a bracket powder receiving assembly provided at the bottom of the housing 21, and a power switch 23 provided on the outer side of the housing 21. The bean grinding assembly inside the housing 21 is provided with a motor 20 for grinding beans and a grinding blade 12. The position of the power switch 23 corresponds to that of the control board 25, and the power switch 23 is connected to the control board 25 for controlling the on / off of the machine.

[0024] For details, see Figure 1 The scale adjustment assembly of the utility model is composed of an adjustment cover 4, a screw a5, a scale plate 6, an upper cover 7, and an adjustment member 9;

[0025] The adjusting cover 4 and the adjusting member 9 are fixed by magnets, the dial 6 is fixed to the adjusting member 9 by screws a5, and the adjusting member 9 is threadedly connected to the upper cover 7;

[0026] By rotating the adjustment cover 4, the adjustment member 9 moves up and down;

[0027] When the adjusting cover 4 is rotated so that the cutter disc 12 in the cavity 16 touches the cutter, it is at zero scale and the adjusting cover 4 is removed. Since the adjusting cover 4 and the adjusting member 9 are only fixed by magnetic attraction, the adjusting cover 4 can be easily removed.

[0028] Then loosen the screw a5 to allow the dial 6 to rotate, and manually move the dial 6 to align the zero position of the scale with the pointer of the upper cover 7. At this time, the scale zero adjustment is completed, and then tighten the screw a5 and put the adjustment cover back to complete the scale calibration.

[0029] It greatly simplifies the scale adjustment method of other machines on the market, allowing users to easily complete the scale calibration work.

[0030] For further information, see Figure 2 The structural shape design of the bean inlet in the utility model is composed of a bean bin 3, a cavity 16, and an upper knife holder 11;

[0031] The bean bin 3 is equipped with a marble screw, the bean bin 3 is mounted on the cavity 16, and the upper tool holder 11 is mounted inside the cavity 16 through the motor shaft;

[0032] The invention adopts a novel design of a bean bin 3 structure that can be directly and quickly disassembled without tools, so that the bean bin 3 can be quickly installed on the cavity 16 in a plug-in manner. When the user is finished using it, the bean bin 3 can be easily removed for cleaning.

[0033] The upper blade holder 11 is provided with a guide thread, which can quickly guide the beans into the space between the blade discs 12 for grinding. The guide thread is designed with a small gap with the bottom of the cavity, so that fine powder can still be guided into the blade disc 12 for grinding without remaining inside the cavity. This design makes the grinding work more complete.

[0034] It is worth noting that, see Figure 3 The bean grinding assembly includes an anti-grinding flying powder structure, which is composed of a plasma generator 22, a plasma fixing seat 35, an inner powder tube 37 and a spring 40;

[0035] During installation, the emission head of the plasma generator 22 is inserted into the plasma fixing seat 35, the plasma fixing seat 35 is fixed on the cavity 16, the inner powder tube 37 is adsorbed on the cavity 16 by a magnet, and the spring 40 is installed on the inner powder tube;

[0036] During grinding, powder particles fall from the inner powder tube 37 into the powder receiving cup 41. At this time, the cross structure at the top of the inner powder tube 37 can break up the powder lumps and smoothly fall into the powder receiving cup 41.

[0037] Secondly, the positive and negative ions emitted by the external plasma device can effectively eliminate the static electricity in the powder and eliminate the problem of powder flying. Finally, by turning the spring 40, the residual powder inside the inner powder tube 37 is ejected, reducing the residual powder inside and allowing the user to experience a good and comfortable powder discharge effect.

[0038] The inner powder tube 37 is magnetically adsorbed on the cavity 16, so when cleaning, the inner powder tube can be directly unplugged, which is convenient for users to operate.

[0039] It is worth noting that see Figure 4 The bracket powder receiving assembly includes a powder receiving positioning structure, which is composed of a bottom plate 32 and a powder receiving cup 41;

[0040] The bottom of the powder cup 41 is equipped with a magnet and the bottom groove of the bottom plate 32 is also equipped with a magnet;

[0041] When in use, the cup 41 is placed directly above the bottom plate 32 and can automatically be positioned at the magnet installation position of the bottom plate through magnetic attraction, making it convenient for the user to place it in the correct position and prevent powder from falling outside the cup.

[0042] In addition, the components designed in this utility model are all universal standard parts or components known to technical personnel in this field. Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. They can be fully implemented by technical personnel in this field. Needless to say, the content protected by this utility model does not involve improvements to internal structures and methods.

[0043] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
