[0039] Referring to Figure 1 , 4 As shown in FIGS. 7 and 13, a coffee bean grinding module includes a power module 100, a grinding module 200, and a receiving module 300. The power module 100 includes a power component 110. The grinding module 200 is detachably mounted at the bottom of the power module 100. The grinding module 200 includes a grinding knife assembly for grinding coffee beans. The grinding knife assembly is connected to the power component 110. The power component 110 is used to provide driving force to the grinding knife assembly. A grinding cavity 201 is provided in the grinding knife assembly. An inlet 202 and an outlet 203 for coffee powder are respectively provided in the upper and lower parts of the grinding cavity 201. The inlet 202 is located in the upper part of the grinding cavity 201, and coffee beans are put into the grinding cavity 201 through the inlet 202. The outlet 203 is located at the lower part of the grinding knife assembly. The receiving module 300 is detachably mounted at the bottom of the grinding module 200. The receiving module 300 includes a receiving housing 310 and a multi-functional cup 320. Scale lines are engraved on the multi-functional cup 320. The multi-functional cup 320 is detachably mounted in the receiving housing 310. The multi-functional cup 320 is used to weigh coffee beans and receive coffee powder. An outwardly protruding stop 301 is provided at the cup mouth of the multi-functional cup 320. A first groove 204 is provided at the top of the grinding module. When the multi-functional cup 320 is buckled upside down on the grinding module, the outwardly protruding stop 301 cooperates with the first groove 204 to integrally buckle the multi-functional cup 320 and the grinding module.

[0040] Among them, the power component 110 includes a drive shaft 111, and an inwardly concave hole 112 is provided on the drive shaft 111. The grinding knife assembly includes a connecting shaft 210, a female knife 220, and a male knife 230. A connecting portion 211 is provided at the top end of the connecting shaft 210. The connecting portion 211 is inserted into the inwardly concave hole 112. The female knife 220 is sleeved outside the male knife 230. The male knife 230 is mounted on the connecting shaft 210, so that the male knife 230 rotates with the connecting shaft 210.

[0041] Before grinding, first take out the multifunctional cup 320 in the accommodation module 300. There are scale lines on the multifunctional cup 320. When the coffee beans are filled to the position of the scale line, the weight of the coffee beans is the optimal gram weight, realizing the coffee beans can be taken without a weighing scale. Then take out the grinding module, place it upside down on the multifunctional cup 320, and then turn the two over together. The coffee beans in the multifunctional cup 320 are poured into the grinding module from the bean inlet 202. Since the cross-section of the grinding chamber 201 is in an inverted conical shape, the coffee beans can be poured in from the bean inlet 202, but cannot flow out from the powder outlet 203. Only after the coffee beans are ground into coffee powder, they flow out from the powder outlet 203. During grinding, place the multifunctional cup 320 into the accommodation housing 310 and then fix it below the grinding module. The grinding module is fixed below the power module 100, and the grinding module starts to grind. The ground coffee powder will fall into the multifunctional cup 320; after grinding, remove the coffee powder accommodation module 300, then take out the multifunctional cup 320, and pour out the coffee in the multifunctional cup 320. Because there is no residual powder, the amount of the ground coffee powder is the amount for making a cup of coffee, avoiding mistakes caused by interference during production and improving the success rate of making coffee.

[0042] To make the multifunctional cup 320 fit tightly with the grinding module, there is an outward convex stop 301 at the mouth of the multifunctional cup 320, and a first groove 204 is provided on the second bracket 240 of the grinding module. The first groove 204 is matched with the outward convex stop 301 ring.

[0043] During the process of grinding coffee powder, a lot of static electricity will be generated. The static electricity will adsorb the coffee powder particles with relatively small mass near the cutter head. However, the coffee powder particles with relatively small mass are a crucial part of coffee extraction. Therefore, static electricity will have a negative impact on coffee production. To address the negative impact caused by static electricity, an emission steel needle 260 is adopted. When the emission steel needle 260 is working, it can make stable air generate positive ions with positive charges and negative ions with negative charges. The positive ions and negative ions neutralize the statically charged coffee powder respectively, so that the coffee powder reaches electrical balance, making the coffee powder not be adsorbed near the cutter head and falling into the multifunctional cup 320 under the action of gravity.

[0044] Refer to Figure 5 、 8, 10. Specifically, the power module 100 further includes a first bracket 120. A power component 110 is fixedly installed on the first bracket 120. The bottom plate of the first bracket 120 is equipped with a first copper column 130. A first contact portion 131 is provided on the first copper column 130. An ionization power supply 400 is also fixedly installed on the first bracket 120. The ionization power supply 400 is connected to the first copper column 130. The grinding module 200 further includes a second bracket 240, a grinding head cover plate 250, and a firing steel needle 260. A second copper column 270 is installed on the top of the second bracket 240. A first contact portion 131 is provided on the first copper column 130. A second contact portion 271 protrudes above the second bracket 240. The grinding head cover plate 250 is installed at the bottom of the second bracket 240. A powder outlet 203 is provided on the grinding head cover plate 250. The firing steel needle 260 is installed on the grinding head cover plate 250, and the firing steel needle 260 is located on one side of the powder outlet 203. The firing steel needle 260 is connected to the second copper column 270. When the power module 100 and the grinding module 200 are combined with each other, the second contact portion 271 contacts the first contact portion 131, so that the ionization power supply 400 supplies power to the firing steel needle 260 through the first copper column 130 and the second copper column 270. After the firing steel needle 260 is energized, it ionizes the air to generate positive ions and negative ions.

[0045] Due to functional requirements, the end of the firing steel needle 260 is very sharp. If it is exposed outside, it will cause harm to consumers and cannot meet the safety regulations requirements. If it is not exposed outside, the generated positive and negative ions cannot neutralize the static electricity of the coffee powder in time, resulting in poor anti-static effect. Therefore, the firing steel needle 260 needs to be hidden in the non-use state.

[0046] Refer to Figure 7 , 13 , 14. Specifically, the grinding module 200 further includes a grinding head cover plate 250, a protection cover 280, and a firing steel needle 260. A powder outlet 203 is provided on the grinding head cover plate 250. The protection cover 280 is installed on the grinding head cover plate 250. The firing steel needle 260 is installed on the grinding head cover plate 250. The protection cover 280 includes an installation portion 281 and a cover portion 282. A sleeve hole 283 is opened on the installation portion 281. A convex column 251 is provided on the grinding head cover plate 250. The convex column 251 passes through the sleeve hole 283. A top plate 252 is fixed at the top of the convex column 251. A first spring 290 is installed between the top plate 252 and the installation portion 281. A needle through hole 284 is opened on the cover portion 282. The needle through hole 284 is in position cooperation with the firing steel needle 260. The cover portion 282 protrudes from the powder outlet 203. After the grinding module 200 and the accommodation module 300 are combined, the cover portion 282 is pushed back into the powder outlet 203 by the accommodation module 300, so that the firing steel needle 260 passes through the needle through hole 284.

[0047] When the accommodation module 300 is not installed, the first spring 290 keeps the protective cover 280 moving downward, thereby hiding the plasma emission steel needle 260 to protect consumers from touching the steel needle, playing a role of self - hiding. During the installation of the accommodation module 300, the multifunctional cup 320 of the accommodation module 300 will contact the protective cover 280 and push and squeeze the protective cover 280 to make the protective cover 280 move upward, exposing the steel needle.

[0048] After the work is completed, when the accommodation module 300 is taken out, the steel needle protective cover 280 rebounds and resets under the action of the first spring 290. Because the gap between the needle through - hole 284 and the steel needle is small, during the rebounding process, the coffee powder adsorbed on the steel needle can be scraped off, playing a role of self - cleaning.

[0049] Because the male knife 230 at the bottom of the grinding module rotates relatively fast and has no protection, if the grinding is started without installing the accommodation module 300, it may cause harm to consumers. Therefore, when the accommodation module 300 is not installed, the grinding module cannot start grinding.

[0050] Refer to Figure 11 、 12 As shown, specifically, the power module 100 further includes a first bracket 120 and a micro - switch 140. A through - hole 121 is opened on the bottom plate of the first bracket 120, and the micro - switch 140 is fixed on the first bracket 120. The micro - switch 140 includes a trigger part 141, and the trigger part 141 is located above the through - hole 121; the grinding module 200 further includes a second bracket 240, a grinding head cover plate 250, and a push rod 2100. The push rod 2100 is inserted through the second bracket 240 and moves up and down within the second bracket 240; the lower end of the push rod 2100 passes through the bottom of the grinding head cover plate 250. After the grinding module 200 is combined with the accommodation module 300, the lower end of the push rod 2100 is pushed by the accommodation module 300, causing the push rod 2100 to move upward, so that the upper end of the push rod 2100 passes through the top of the second bracket 240 and touches the trigger part 141 through the through - hole 121. A second spring 2200 is sleeved on the push rod 2100.

[0051] When the accommodation module 300 is not installed, the push rod 2100 protrudes downward under the action of the second spring 2200. At this time, the push rod 2100 does not touch the trigger part 141 of the micro - switch 140, and the machine cannot be started.

[0052] When the accommodation module 300 is installed, the accommodation module 300 pushes the push rod 2100 upward, causing the push rod 2100 to touch the trigger part 141 through the through - hole 121, triggering the micro - switch 140, and starting the grinding module, avoiding accidental operation and injury to consumers and protecting the personal safety of consumers.

[0053] Refer toFigure 8 As shown, the grinding module 200 further includes a second bracket 240, a female cutter copper sleeve 2300, and a bearing copper sleeve 2400. The second bracket 240, the female cutter copper sleeve 2300, and the bearing copper sleeve 2400 are integrally injection-molded. The female cutter copper sleeve 2300 and the bearing copper sleeve 2400 are located on the same axis. The female cutter copper sleeve 2300 is sleeved on the connecting shaft 210, and the female cutter 220 is installed inside the bearing copper sleeve 2400.

[0054] During specific processing, first, the female cutter copper sleeve 2300 and the bearing copper sleeve 2400 are processed well, and a machining allowance is reserved for the bearing copper sleeve 2400. Then, the female cutter copper sleeve 2300 and the bearing copper sleeve 2400 are embedded in a bracket mold for injection molding. After the injection molding is completed, the bearing copper sleeve 2400 is processed and corrected with the female cutter copper sleeve 2300 as the reference to improve the coaxiality between the bearing copper sleeve 2400 and the female cutter copper sleeve 2300.

[0055] Refer to Figure 8 As shown, the female cutter copper sleeve 2300 is provided with a first step position 2310 and a second step position 2320. The first step position 2310 is located above the second step position 2320, and there is a spaced arrangement between the first step position 2310 and the second step position 2320. The first bearing 2500 is installed on the first step position 2310, and the second bearing 2600 is installed on the second step position 2320. The first bearing 2500 and the second bearing 2600 are sleeved on the connecting shaft 210. Since the connecting shaft 210 is fixed by double bearings, it is ensured that there is a high-precision coaxiality among the connecting shaft 210, the female cutter copper sleeve 2300, and the bearing copper sleeve 2400.

[0056] Refer to Figure 8 、 9 As shown, since the fineness of coffee bean grinding is adjusted by adjusting the gap between the male cutter 230 and the female cutter 220, the grinding module 200 further includes an adjusting disk 2700 and an adjusting knob 2800. The adjusting disk 2700 is installed on the male cutter 230. An installation position 2710 is provided inside the adjusting disk 2700. The adjusting knob 2800 is located inside the installation position 2710, and the adjusting knob 2800 is threadedly connected to the connecting shaft 210, so that the male cutter 230 is fixed on the connecting shaft 210 by the adjusting disk 2700 and the adjusting knob 2800. The height of the male cutter 230 can be adjusted axially along the connecting shaft 210 by rotating the adjusting knob 2800 and it can rotate following the connecting shaft 210.

[0057] However, during the grinding process, under the reaction force of the male cutter 230, the adjusting knob 2800 becomes loose, resulting in a deviation in the fineness of coffee bean grinding.

[0058] To this end, a plurality of second grooves 2711 are arranged on the inner wall of the installation position 2710; a marble 2810 is arranged on the outer wall of the adjustment knob 2800, and the marble 2810 is stuck into the second groove 2711. The marble 2810 rolls into different second grooves 2711 as the adjustment knob 2800 rotates. By the cooperation of the marble 2810 and the second groove 2711, the reaction force generated during the grinding of the male knife 230 is resisted, so as to maintain the self-locking of the adjustment knob 2800, realize the anti-loosening function, and the lateral marble 2810 gives an obvious tactile feedback during adjustment to obtain the information of the adjustment gear.

[0059] Refer to Figure 7 , 11 As shown, when the male knife 230 and the female knife 220 grind coffee beans, it is inevitable to adsorb some coffee powder. To this end, a cleaning brush 2720 is fixed on the adjustment disk 2700. The cleaning brush 2720 faces the powder outlet 203.
