[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 3 As shown, an extraction and grinding integrated coffee machine includes a main body 100, a hot water mechanism 200, a grinding mechanism 300, and an extraction chamber 400; the main body 100 includes a front shell 110, and the front shell 110 is provided with a connecting portion 120, and the connecting portion 120 is provided with a first water outlet 130, and the first water outlet 130 is parallel to the horizontal plane; the hot water mechanism 200 is arranged in the main body 100, and the hot water mechanism 200 is connected with the first water outlet 130 through a pipeline, and the hot water mechanism 200 is used to supply high-pressure hot water; the grinding mechanism 300 is arranged on the side of the main body 100, and the grinding mechanism 300 is used to grind coffee beans, and a receiving space 101 is formed below the grinding mechanism 300 The extraction chamber 400 is detachably mounted on the adapter 120. The extraction chamber 400 comprises a first cover body 410 and a second cover body 420 which are detachably connected to each other. The first cover body 410 is detachably connected to the adapter 120. The second cover body 420 is used to receive the coffee powder ground by the grinding mechanism 300 in the receiving space 101. A water inlet 411 is provided on the first cover body 410. A second water outlet 421 is provided on the side wall of the second cover body 420. When the first cover body 410 and the second cover body 420 are combined into a whole, they are installed on the adapter 120 so that the first water outlet 130 is inserted into the water inlet 411 and the second water outlet 421 is vertically oriented to the horizontal plane to facilitate the collection of coffee.

[0032] During the production, the extraction chamber 400 is split, and the split second cover body 420 is placed under the grinding mechanism 300, and the bean grinding button is pressed, the grinding mechanism 300 starts to grind the coffee beans, and the ground coffee powder falls into the second cover body 420. After the grinding is completed, the powder is pressed with a powder hammer, and the upper cover and the second cover body 420 are recombined into the extraction chamber 400; then the extraction chamber 400 is installed on the adapter 120, and the extraction button is pressed to make the hot water generated in the hot water mechanism 200 enter the extraction chamber 400 to extract coffee; therefore, the present coffee machine has two major functions of coffee bean grinding and coffee extraction, so that novice users do not need to switch different machines for operation, avoid mistakes caused by interference during operation, and improve the success rate of making espresso.

[0033] Because the coffee powder is relatively loose when it is powdered, the accumulation process is in the shape of a mountain, which is high in the middle and low around. Therefore, the accumulation height of the coffee powder will be higher than the depth of the powder bowl of the second cover body 420, making it easy for the coffee powder to overflow from the second cover body 420. Therefore, a powder receiving ring 500 is also provided. The powder receiving ring 500 and the second cover body 420 are detachably connected, so that the powder receiving ring 500 and the second cover body 420 are placed as a whole in the receiving space 101.

[0034] The powder receiving ring 500 temporarily expands the capacity of the second cover body 420 to prevent coffee powder from overflowing during the grinding process.

[0035] Reference Figure 3 , 4 As shown in FIG. 10 , a first opening 501 is formed at the top of the powder receiving ring 500 , and a second opening 502 is formed at the bottom of the powder receiving ring 500 . The coffee powder passes through the first opening 501 and the second opening 502 in sequence and then falls into the second cover body 420 .

[0036] Specifically, the powder receiving ring 500 is divided into a first ring body portion 510 and a second ring body portion 520 from top to bottom, and the second cover body 420 can be detachably installed in the second opening 502, so that after receiving the coffee powder, the powder receiving ring 500 can be retained and the coffee powder in the second cover body 420 can be directly compacted with a powder hammer. After the compaction is completed, the powder receiving ring 500 can be removed.

[0037] In order to allow the coffee powder to fall into the second cover 420 better, the first ring portion 510 is trumpet-shaped.

[0038] The working method of the powder receiving ring 500 is explained again. After the powder receiving ring 500 is connected and combined with the second cover body 420, the combination is placed under the grinding mechanism 300. A base with a groove is provided under the grinding mechanism 300. The second cover body 420 is fixedly placed in the groove so that the second cover body 420 and the grinding mechanism 300 are concentric. The receiving space 101 can completely accommodate the combination between the second cover body 420 and the powder receiving ring 500, so as to avoid the overflow of coffee powder during the grinding process.

[0039] Reference Figure 1 As shown, the hot water mechanism 200 includes a water tank 210, a heating element 220, and a water pump 230. The water tank 210 is connected to the inlet of the heating element 220 through a pipeline, the outlet of the heating element 220 and the inlet of the water pump 230 are connected through a pipeline, and the outlet of the water pump 230 and the first water outlet 130 are connected through a pipeline.

[0040] During operation, water in the water tank 210 enters the heating element 220 through the pipeline, and the heating element 220 quickly heats the water to a preset temperature. The hot water generated by the heating is pressurized by the water pump 230 and pumped out through the first water outlet 130 into the extraction chamber 400 to provide pressure for making coffee.

[0041] At the same time, a one-way valve is also installed at the first water outlet 130. When the extraction chamber 400 is taken out, the one-way valve can close the first water outlet 130 to prevent high-pressure hot water from spraying. When the first water outlet 130 is inserted into the water inlet 411, the push rod in the water inlet 411 pushes the valve core in the one-way valve backwards, so that the first water outlet 130 is unblocked and the high-pressure hot water enters the extraction chamber 400.

[0042] At the same time, a solenoid valve 240 is installed on the pipeline between the outlet and the first water outlet nozzle 130. After the extraction chamber 400 is removed, the solenoid valve 240 starts to work and switches to the pressure relief pipeline to relieve the pressure of the pipeline.

[0043] Reference Figure 6 , 7 As shown, the grinding mechanism 300 includes a grinding motor 310 and a grinding core 320 . An inner hole 311 is provided on the output shaft of the grinding motor 310 . The grinding core 320 includes a rotating shaft 321 , which is detachably inserted into the inner hole 311 .

[0044] When reassembling the grinding core 320 and the grinding motor 310, the rotating shaft 321 and the inner hole 311 need to be accurately aligned so that the rotating shaft 321 can be accurately inserted into the inner hole 311. However, the rotating shaft 321 of the grinding core 320 is rotatable, which causes deviation after the rotating shaft 321 rotates at a small angle, affecting the accuracy of inserting the rotating shaft 321 into the inner hole 311, causing trouble to the user.

[0045] To this end, in this embodiment, the cross-sections of the inner hole 311 and the rotating shaft 321 are both regular polygons, the number of sides of the inner hole 311 is A, A=2n, and the number of sides of the rotating shaft 321 is B, B=n; wherein n is an integer and is greater than 4.

[0046] In this embodiment, n is 6, the number of sides of the inner hole 311 is 12, and the number of sides of the rotating shaft 321 is 6. Through the cooperation between the regular dodecagonal inner hole 311 and the regular hexagonal rotating shaft 321, during the alignment installation, even if the rotating shaft 321 rotates at a small angle, the rotating shaft 321 can be inserted into the inner hole 311 for coupling, which makes the operation convenient and quick.

[0047] Reference Figures 5 to 7 As shown, the grinding motor 310 is installed in the first shell 330, and the first shell 330 is provided with a first end face 331. The grinding core 320 is installed in the second shell 340, and the second shell 340 is provided with a second end face 341. After the grinding motor 310 and the grinding core 320 are combined, the first end face 331 and the second end face 341 are in contact with each other.

[0048] A first through hole 332 is provided in the first shell 330, the first through hole 332 opens at the first end surface 331, and a first magnet 350 is installed in the first through hole 332; a second through hole 342 is provided in the second shell 340, the second through hole 342 opens at the second end surface 341, and a second magnet 360 is installed in the second through hole 342. Through the above structure, the first magnet 350 and the second magnet 360 are directly magnetically attracted and are not isolated by the first shell 330 and the second shell 340, thereby ensuring that the attraction force between the first magnet 350 and the second magnet 360 is large, and ensuring that the grinding core 320 will not fall off after the grinding core 320 is combined with the grinding motor 310.

[0049] In order to further increase the force between the first magnet 350 and the second magnet 360 , the first through hole 332 , the second through hole 342 , the first magnet 350 , and the second magnet 360 are all T-shaped.

[0050] Reference Figure 8 As shown, the grinding mechanism 300 also includes a plasma radiator head 370, which is installed in the second shell 340. The second shell 340 is also provided with a powder outlet end 343, and the powder outlet end 343 is provided with a powder outlet 344. The tip of the plasma radiator head 370 is located at the periphery of the powder outlet 344. The plasma radiator head 370 generates a large amount of positive and negative charges, which can neutralize the coffee powder, eliminate the static electricity of the coffee powder, and avoid the generation of flying powder.

[0051] The closer the coffee powder is to the plasma emitter head during its falling process, the better the effect of static elimination is. It only falls freely under the action of gravity to form an accumulation. The static elimination is reduced at a position far away from the plasma emitter head, and a small amount of coffee powder will fly under the action of static electricity, and the scattered position is irregular. Therefore, the coffee powder will accumulate faster at a position close to the plasma emitter head. When the height of the accumulation fills the distance from the plasma emitter head to the powder bowl of the second cover body 420, the effect of the plasma emitter head will be weakened, and the coffee powder will not eliminate static electricity, and flying powder will be generated.

[0052] For this reason, in this embodiment, three pairs of plasma emission heads are used, and the three pairs of plasma emission heads are arranged in an equilateral triangle, which can more fully eliminate the static electricity of coffee powder in a limited space.

[0053] Reference Figure 3 , 9 As shown, in this embodiment, the upper cover and the second cover body 420 are combined by threaded connection to form an extraction chamber 400, wherein the outer side of the upper cover is provided with a buckle block 412, and the adapter 120 is provided with a buckle position 121, and the buckle block 412 can be screwed into the buckle position 121, so that the extraction chamber 400 is fixed in the adapter.

[0054] The inner side of the upper cover is an internal thread that can be connected to the external thread of the second cover body 420, and a sealing silicone pad is installed in the middle of the inner side of the upper cover. The upper cover and the second cover body 420 are screwed together to form a sealed cavity for extracting coffee.

[0055] In the description of this specification, the description with reference to the terms "some embodiments" or "it is conceivable that" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
