[0002] At present, both semi-automatic and fully automatic coffee machines include a grinding program for grinding coffee beans into coffee powder. Usually, a coffee machine uses a motor to drive a grinding knife to rotate, thereby crushing coffee beans. However, during the crushing and grinding process of coffee beans, due to friction with the grinding knife, static electricity will be generated, and the coffee powder will carry a certain amount of charge, resulting in the problem of powder flying. Specifically, it is manifested as adsorption or scattering caused by static electricity, which leads to insufficient cleanliness of the coffee machine and inconvenience to users.

[0003] Chinese Utility Model Patent with Publication No. CN206183046U discloses a structure for preventing static electricity generation of coffee powder. By adding a plasma generator in the coffee channel, there are two steel needles, a positive electrode and a negative electrode, on the plasma generator, which respectively ionize air molecules to generate positive and negative ions to neutralize the charge carried by the coffee powder, thus solving the problem of powder flying caused by static electricity generated when coffee beans are ground by a cutter.

[0004] However, the steel needles of the plasma generator in the above coffee machine are arranged in the powder outlet channel of the coffee powder. With long-term use, the coffee powder will cover the steel needles of the plasma generator, affecting the effect of the plasma generator and further resulting in the phenomenon of secondary powder flying.

[0009] On the one hand, a grinding mechanism is applied to a grinder provided with a powder outlet, and includes:

[0010] The powder channel assembly is provided with a powder outlet channel communicating with the powder outlet on the grinder.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific implementation manners and are not intended to limit the present utility model.

[0032] In the present utility model, the so-called "first" and "second" do not represent specific quantities and sequences, but are only used for name distinction.

[0033] On the one hand, as Figure 1 and Figure 2 、 Figure 3 shown, a plasma structure in an embodiment of the present utility model is applied to a powder grinding mechanism provided with a flour outlet channel 201, and includes:

[0034] An ionization assembly 3, including a plasma generator 31, the plasma generator 31 is provided with an electrode needle unit 311 for eliminating the static electricity generated by coffee powder, and the ionization end of the electrode needle unit 311 is arranged outside the vertical projection range of the outlet of the flour outlet channel 201.

[0035] By setting the ionization end of the electrode needle unit 311 outside the vertical projection range of the outlet of the powder outlet channel 201, the above plasma structure avoids the ionization end of the electrode needle unit 311 being easily covered by coffee powder during use, which may affect the decline of the ion removal ability; at the same time, it reduces the possibility of the electrode needle unit 311 needing to be cleaned.

[0036] On the one hand, as Figure 1 and Figure 2 , Figure 3 shown, a grinding mechanism in an embodiment of the present invention is applied to a grinder 1 provided with a powder outlet 101 and includes:

[0037] A powder channel assembly 2 is provided with a powder outlet channel 201 communicating with the powder outlet 101 on the grinder 1;

[0038] An ionization assembly 3 includes a plasma generator 31. The plasma generator 31 is provided with an electrode needle unit 311 for eliminating the static electricity generated by coffee powder. The ionization end of the electrode needle unit 311 is set outside the vertical projection range of the outlet of the powder outlet channel 201. Specifically, the plasma generator 31 is composed of positive and negative electrodes. By inputting a rated voltage and outputting a voltage of 3 kV to 5 kV, positive and negative ions are released to neutralize the electricity in the coffee powder, solving the problem of charged powder adhesion during the dropping process of coffee powder.

[0039] In one embodiment, the electrode needle unit 311 includes a first electrode needle 312 and a second electrode needle 313 arranged in parallel. Specifically, the connection line between the installation positions of the first electrode needle 312 and the second electrode needle 313 is arranged at an angle with respect to the center line of the powder outlet channel 201, and the range of the angle is 0° to 90°. In this way, through the first electrode needle 312 and the second electrode needle 313 arranged at an angle, the ionization range of the electrode needle unit 311 is increased, and the ionization effect is optimized.

[0040] In one embodiment, the ionization assembly 3 further includes a mounting seat 32 snap-connected to the mounting housing of the coffee machine, and the plasma generator 31 is fixedly installed on the mounting seat 32. In this way, the plasma generator 31 is installed through the mounting seat 32, which facilitates the modular installation of the ionization assembly 3.

[0041] In one embodiment, the mounting base 32 is provided with a mounting cavity 301 and an ionization cavity 302. The ionization cavity 302 is provided with an ionization outlet facing downward of the powder outlet channel 201. The connecting end of the electrode needle unit 311 is arranged in the mounting cavity 301, and the ionization end is arranged in the ionization cavity 302 and faces the ionization outlet. In this way, by arranging the entire electrode needle unit 311 inside the mounting base 32, it is possible to prevent coffee powder floating outside the mounting base 32 from gathering in the ionization cavity 302 of the mounting base 32, keeping the electrode needle unit 311 in a clean state.

[0042] In one embodiment, the first electrode needle 312 and the second electrode needle 313 are arranged in parallel. In this way, the first electrode needle 312 and the second electrode needle 313 arranged in parallel are simple to install, can reduce the injection molding production difficulty of the mounting base 32, and are convenient for reducing production costs.

[0043] In a specific embodiment, the plane formed by the center lines of the first electrode needle 312 and the second electrode needle 313 is perpendicular to the center of the powder outlet channel 201. In this way, the positive and negative ions emitted by the electrode needle unit 311 can completely cover the cross-section of the outlet of the powder outlet channel 201, fully neutralize the electric charge carried by the coffee powder, and the effect of eliminating static electricity is remarkable.

[0044] In one embodiment, the distance between the ionization end of the electrode needle unit 311 and the outlet of the powder outlet channel 201 is 5 cm to 12 cm. In this way, the applicant has obtained through experiments that when the distance between the ionization end and the outlet of the powder outlet channel 201 is 5 cm to 12 cm, the ionization effect is good, and the coffee powder will not float onto the mounting base 32. At the same time, it adapts to the housing size of the existing coffee machine.

[0045] On the one hand, a coffee machine in an embodiment of the present invention includes a mounting housing and a grinding mechanism. The grinding mechanism is arranged on the mounting housing.

[0046] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0047] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
