[0071] The embodiment is provided with two first receiving containers 501:

[0072] As Figure 7 shown, the first receiving container 501 can be used only for collecting the ground powder, at this time, the first receiving container 501 will not trigger the 503 due to different specifications, that is, the water supply of the water tank 103 and the heating of the heating element 104 will not be started;

[0073] As Figure 8 shown, when the second specification of the first receiving container 501 is put in, the first receiving container 501 will trigger the 503 due to different specifications, at this time, it can be used for collecting coffee powder and brewing coffee, see the specific description as follows:

[0074] Focus on the combination Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 The host body 10 is provided with a water tank 103. After the coffee beans are ground and enter the first receiving container 501 (i.e. coffee basket), the water in the water tank 103 is heated by the heating element 104, and the heated water is poured into the first receiving container 501 (i.e. coffee basket) to brew coffee. The brewed coffee then flows into the second receiving container 502 (i.e. coffee cup). When the second receiving container 502 is placed, the trigger mechanism is triggered to discharge the brewed coffee into the second receiving container 502. The specific structure is as follows:

[0075] The host body 10 is provided with a second container placement position 1013 for placing the second receiving container 502. The second container placement position 1013 is located below the first container placement position 1012. The host body 10 is provided with a discharge port 5011 below the first receiving container 501 and a receiving port 5021 above the second receiving container 502. The receiving port 5021 is opposite to the discharge port 5011. The host body 10 is provided with a second rotating shaft 5042. The second rotating shaft 5042 is provided with a second trigger 5041. The first receiving container 501 is provided with a third rotating shaft 5043 and a third elastic member 5044. The third rotating shaft 5043 is movably provided with a third trigger 505. The third trigger 505 corresponds to the second trigger 5041. The third trigger 505 is provided with a blocking part 5051. Under the action of the third elastic member 5044, the blocking part 5051 blocks the discharge port 5011. When the second receiving container 502 is placed on the second container placement position 1013, the second receiving container 502 triggers the second trigger 5041. The second trigger 5041 triggers the third trigger 505. The blocking part 5051 moves and opens the discharge port 5011.

[0076] The third rotating shaft 5043 is arranged on the side of the discharge port 5011. The third trigger 505 is provided with a ring sleeve 5052 at one end. The blocking part is movably arranged in the middle of the ring sleeve 5052. The ring sleeve 5052 is provided with an overflow port 5053. The overflow port 5053 is located at least on one side of the outer end of the third trigger 505. The host body 10 is provided with a first hook 5045. The second trigger 5041 is provided with a second hook 5046. The first end of the second trigger 5041 is movably arranged on the second rotating shaft 5042. The middle part is hung on the first hook 5045 through the second hook 5046. The second end of the second trigger 5041 corresponds to the third trigger 505.

[0077] When the second specification of the first receiving container 501 is put in, the water in the water tank 103 is heated by the heating element 104 due to the triggering action of the second trigger 5041. After the coffee beans are ground and enter the first receiving container 501 (i.e. the coffee basket), the heated water is poured into the first receiving container 501 to brew coffee. After the brewing is completed, the second receiving container 502 is placed in the second container placement position 1013. The top pressing protrusion 5022 at the top of the second receiving container 502 triggers the second trigger 5041. The second trigger 5041 swings upward and triggers the third trigger 505. The blocking part 5051 is separated from the discharge port 5011. The brewed coffee flows out of the discharge port 5011 and enters the receiving port 5021 of the second receiving container 502. Since the ring sleeve 5052 is arranged on the third trigger 505, the spilling of the coffee when it flows out can be reduced, thereby reducing pollution and waste and allowing the coffee to flow out of the overflow port 5053 to the receiving port 5021.

[0078] Please focus on Figure 14 , Figure 15 , the main body 10 is also provided with a detachable material box 105. The material box 105 is provided with a box cover 106 at the opening position. The fourth trigger 71 is arranged on the lower side of the box cover 106. The fifth pivot shaft 724 is arranged on the material box 105. The fifth trigger 72 is movably arranged on the fifth pivot shaft 724. The trigger head 723 is arranged at the lower end of the fifth trigger 72. The fifth trigger switch 721 is arranged below the trigger head 723. When the material box 105 is placed on the main body 10 and the box cover 106 is covered on the material box 105, the fifth trigger 72 swings under the action of the fourth trigger 71 and presses down the fifth trigger switch 721 through the trigger head 723. The control circuit board makes the driving mechanism 1022 conductive. The grinding part 2114 works under the action of the driving mechanism 1022. If the material box 105 is taken out of the main body 10 or the box cover 106 is taken out of the material box 105, the fifth trigger 72 is reset under the action of the fifth elastic member 722. The fifth trigger switch 721 is disconnected. The control circuit board disconnects the power supply of the driving mechanism 1022, thereby protecting the user.

[0079] The above embodiments are not exhaustive and there can be other unlisted embodiments. Any replacement and improvement without violating the concept of the present application is within the protection scope of the present application.
