[0044] Specifically, when the bean box 610 is installed in the receiving groove 110, the cover is in a closed state, the first recognition component recognizes that the bean box 610 is installed in the receiving groove 110, and sends a first electrical signal to the control module, so that the control module controls the driving member 310 to work, and the transmission member 320 can drive the grinding assembly 611 in the bean box 610 to rotate, so that the grinding assembly 611 grinds the coffee beans in the bean box 610. After the coffee beans are ground into coffee powder, the water tank 200 injects water into the bean box 610 through the water inlet hole 421 to brew coffee; when the bean box 610 is switched to the powder box 620, the cover is in an open state, and the user takes out the bean box 610 through the opening 120 and installs the powder box 620 in the receiving groove 110, and then the cover is closed. Switching from the open state to the closed state, the second identification component recognizes that a powder box 620 or a capsule box 630 is installed in the receiving slot 110, and sends a second electrical signal to the control module, and the water tank 200 injects water into the bean box 610 through the water inlet hole 421 to brew coffee. When the powder box 620 is installed in the receiving slot 110, a third electrical signal is sent to the control module, and the piercing member 420 pierces the capsule to allow the coffee solvent in the capsule to flow out, and the water tank 200 injects water into the bean box 610 through the water inlet hole 421 to brew coffee. The multifunctional coffee machine is compatible with the bean box 610, the powder box 620 and the capsule box 630 to adapt to the three raw materials of coffee beans, coffee powder and coffee solvent, which can improve the versatility of the multifunctional coffee machine.

[0045] It should be noted that the bean box 610, the powder box 620 and the capsule box 630 can all be detachably installed in the receiving slot 110.

[0050] For example, at least two magnets are provided in the bean box 610, and at least one magnet is provided in the powder box 620 and the capsule box 630 respectively. The number of magnets in the powder box 620 is equal to the number of magnets in the capsule box 630, and the number of magnets in the bean box 610 is greater than the number of magnets in the powder box 620. When the bean box 610 is installed in the receiving slot 110, the magnet in the bean box 610 triggers the first identification component. When the powder box 620 or the capsule box 630 is installed in the receiving slot 110, the magnet of the powder box 620 or the capsule box 630 triggers the second identification component, so that the first identification component can identify the bean box 610, and the second identification component can identify the powder box 620 or the capsule box 630.

[0051] As another embodiment, at least one magnet is provided in the bean box 610, and no magnet is provided in the powder box 620 and the capsule box 630. When the bean box 610 is installed in the receiving slot 110, the magnet in the bean box 610 triggers the first identification component. When the powder box 620 or the capsule box 630 is installed in the receiving slot 110, the magnet of the powder box 620 or the capsule box 630 triggers the second identification component. The second identification component does not sense the change in the magnetic field, so that the first identification component can identify the bean box 610 and the second identification component can identify the powder box 620 or the capsule box 630. No further details are given here.

[0052] In some embodiments of the present invention, the machine body 100 is provided with a first prompt component and a second prompt component connected to the control module. When the first recognition component recognizes that a bean box 610 is installed in the receiving slot 110, the first prompt component sends a first prompt signal, and the first prompt signal can prompt the user that the coffee machine is in a bean grinding state. When the second recognition component recognizes that a powder box 620 or a capsule box 630 is installed in the receiving slot 110, the second prompt component sends a second prompt signal, and the second prompt signal can prompt the coffee machine to be in a coffee brewing state.

[0053] It should be noted that when the coffee machine is in the bean grinding state, the driving member 310 drives the transmission member 320 to rotate, and the transmission member 320 is in transmission connection with the grinding assembly 611 in the bean box 610, so that the grinding assembly 611 rotates, thereby grinding the coffee beans in the bean box 610. When the coffee machine is in the coffee brewing state, the water in the water tank 200 is heated by the heating assembly, and the water in the water tank 200 is injected into the powder box 620 or the capsule box 630 to achieve the coffee brewing function.

[0054] It should be pointed out that the first prompt signal can be voice or light, and the second prompt signal can be voice or light. For example, the first prompt component and the second prompt component are LED diodes respectively. When the coffee machine is in the bean grinding state, the first prompt component lights up and the second prompt component turns off. When the coffee machine is in the coffee brewing state, the first prompt component turns off and the second prompt component lights up. There is no limitation here.

[0055] Reference Figures 7 to 9 In some embodiments of the present invention, the cover body 410 includes a first cover body 411 and a second cover body 412 connected to the first cover body 411. The first cover body 411 and the second cover body 412 are enclosed to form an inner cavity. A first water pipe 440 is provided in the inner cavity. The first cover body 411 is provided with a first joint 430. The first joint 430 is connected to the water inlet hole 421 through the first water pipe 440. The machine body 100 is provided with a second joint 130 connected to the water tank 200. When the cover body assembly 400 is in a closed state, the first joint 430 is connected to the second joint 130, which can facilitate the coffee machine to inject hot water into the powder box 620 or the capsule box 630.

[0056] It should be noted that when the cover assembly 400 is in the open state, the first joint 430 is separated from the second joint 130 , which is not limited here.

[0057] Reference Figure 4 In some embodiments of the present invention, the multifunctional coffee machine further includes a second water pipe 140, a first pump body assembly and a second pump body assembly. The second joint 130 is connected to the water tank 200 through the second water pipe 140. The first pump body assembly and the second pump body assembly are respectively arranged on the second water pipe 140. The first pump body assembly is used to pump out the water tank 200 and discharge it from the second joint 130. The second pump body assembly is used to blow air into the second water pipe 140 and blow the water in the second water pipe 140 out of the second joint 130. After the coffee machine finishes brewing coffee each time, the heating assembly stops heating in advance and the first pump body assembly stops working. After that, the airway of the second pump body assembly works to blow air into the second water pipe 140 to blow away the water in the second water pipe 140, so as to prevent the cold water in the second water pipe 140 from entering the bean box 610 or the powder box 620 for the next coffee brewing, thereby improving the taste of the coffee.

[0058] In some embodiments of the present invention, a heating component and a temperature detection component electrically connected to the control module are provided in the body 100. The heating component is used to heat the water in the second water pipe 140, and the temperature detection component is used to detect the temperature in the heating component. The water outlet temperature of the water tank 200 can be controlled to improve the taste of the coffee.

[0059] Specifically, when brewing coffee, the heating component is preheated, and the temperature detection component detects the temperature of the heating component. If the water in the water tank 200 does not reach the water outlet temperature, the heating tube continues to heat first. After the heating component is preheated, the first pump body component pumps a small amount of water into the second water pipe 140 to make the water outlet temperature of the second joint 130 reach the preset value.

[0060] It should be noted that the temperature detection component can be an NTC temperature sensor or a thermocouple temperature sensor, and the heating component can be a heating tube or a heating sheet, etc., which will not be described in detail here.

[0061] In some embodiments of the present invention, the cover body 410 is rotatably connected to the machine body 100, and the multifunctional coffee machine is provided with a locking structure, which is used to lock the cover body 410 and the machine body 100, thereby improving the reliability of the multifunctional coffee machine.

When the locking member 510 rotates, one end of the locking member 510 can enter or exit the locking slot 150. When the cover body assembly 400 is in a closed state, one end of the locking member 510 enters the locking slot 150 and abuts against the side wall of the locking slot 150, thereby improving the reliability of the use of the multi-functional coffee machine.

[0063] It should be noted that the locking structure can also be a locking member 510 provided on the lock body and a locking tongue provided on the cover body. The locking member 510 is provided with a locking groove 150. The user can lock the cover body by pressing the locking tongue into the locking groove 150, so that the cover body is stably in a closed state. When the cover body is switched from a closed state to an open state, the locking tongue can be pressed again to make the locking tongue exit the locking groove 150, thereby unlocking the cover body. There is no limitation here.

[0064] In some embodiments of the present invention, the locking structure also includes a sliding member 520 slidably disposed on the cover body 410, and the sliding member 520 is connected to the other end of the locking member 510 to drive the locking member 510 to rotate, which can facilitate the user to drive one end of the locking member 510 to exit the lock slot 150.

[0065] Specifically, when the opening 120 needs to be opened, the user can drive the sliding member 520 to move. When the sliding member 520 moves, it can drive the locking member 510 to rotate, which can facilitate the user to drive one end of the locking member 510 to exit the locking slot 150.

[0066] In some embodiments of the present invention, the locking structure also includes an elastic member 530, which is used to allow one end of the locking member 510 to enter the locking groove 150. When the cover body is in a closed state, one end of the locking member 510 can automatically enter the locking groove 150, thereby preventing the cover body from being unlocked due to user misoperation.

[0067] It should be noted that the elastic member 530 is a component with axial elastic deformation, such as a compression spring or a rubber component. One end of the elastic member 530 abuts against the locking member 510, and the other end of the elastic member 530 abuts against the cover body 410. When the cover is in a closed state, one end of the locking member 510 can automatically enter the locking groove 150, thereby preventing the cover from being unlocked due to user misoperation.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
