The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0031] Combine Figure 1 and Figure 3As shown, a coffee water circuit control connection structure 10 according to an embodiment includes a water pump assembly 100 for providing water to a coffee machine; a brewing assembly 200 for extracting coffee liquid; and a hot extraction assembly 300 for increasing the water temperature.

[0032] The three-way interface 700 for switching between cold and hot extraction is used to connect the water pump assembly 100, the brewing assembly 200 and the hot extraction assembly 300; the coffee waterway control connection structure 10 also includes a first solenoid valve 310 and a second solenoid valve 320, the first solenoid valve 310 is provided with a first flow port 3110, a second flow port 3120 and a third flow port 3130; the first flow port 3110 is connected to the water outlet end of the water pump assembly 100, the second flow port 3120 and the third flow port 3130 are connected ... The second flow port 3120 is in communication with the first port of the hot / cold extraction switching three-way interface 700, and the third flow port 3130 is in communication with the water inlet of the hot extraction assembly 300. When the first solenoid valve 310 is used for hot extraction, the first flow port 3110 and the third flow port 3130 are open, and the second flow port 3120 is closed. The first solenoid valve 310 is also used for cold extraction, with the first flow port 3110 and the second flow port 3120 being open, and the third flow port 3130 being closed.

[0033] The second solenoid valve 320 is provided with a fourth flow port 3210 and a fifth flow port 3220. The fourth flow port 3210 is in communication with the second port of the hot / cold extraction switching three-way interface 700. The fifth flow port 3220 is in communication with the water outlet of the hot extraction component 300. The third port of the hot / cold extraction switching three-way interface 700 is connected to the brewing component 200. When the second solenoid valve 320 is used for hot extraction, the fourth flow port 3210 and the fifth flow port 3220 are open. When the second solenoid valve 320 is also used for cold extraction, at least one of the fourth flow port 3210 and the fifth flow port 3220 is closed.

[0034] It can be understood that by setting the first solenoid valve 310 and the second solenoid valve 320 in the coffee water path control connection structure 10, and the first solenoid valve 310 is provided with a first flow port 3110, a second flow port 3120 and a third flow port 3130, because the first flow port 3110 is connected to the water outlet end of the water pump assembly 100, when the water pump assembly 100 draws water from the outside, the water source will flow into the first flow port 3110 through the water outlet end of the water pump assembly 100, and at the same time, because the third flow port 3130 is connected to the water inlet end of the hot extraction assembly 300; when hot extraction is performed, the water source will flow from the first flow port 3110 to the third flow port 3130, and at the same time, the second flow port 3120 is closed, so that the water source flows into the hot extraction assembly 300 through the water inlet end of the hot extraction assembly 300 to perform liquid heating extraction processing. After the hot extraction assembly 300 is heated, the water source will pass through the fifth flow port 3130 of the second solenoid valve 320. The flow from the flow port 3220 to the fourth flow port 3210, and finally flows from the fourth flow port 3210 into the second port of the cold / hot extraction switching three-way interface component 700. Since the port of the cold / hot extraction switching three-way interface component 700 is connected to the brewing component 200, the water source flows into the brewing component 200 for hot extraction of coffee powder. Since the second flow port 3120 is connected to the first port of the cold / hot extraction switching three-way interface component 700, when cold extraction is performed, the water source enters the cold / hot extraction switching three-way interface component 700 through the first flow port 3110 and the second flow port 3120, thereby performing cold water extraction of coffee. By controlling the opening and closing states of the flow ports of the first solenoid valve 310 and the second solenoid valve 320, it is convenient to control the switching between the cold extraction mode and the hot extraction mode of the coffee machine, so that the coffee extraction mode can be freely switched on the same coffee machine, thereby meeting the different needs of users.

[0035] In another embodiment, the water source is used to provide cold water for cold extraction.

[0036] like Figure 1 As shown, further, the third flow port 3130 is a one-way valve. It can be understood that the third flow port 3130 is designed as a one-way valve. The characteristic of a one-way valve is that it only allows liquid to flow in one direction and prevents it from flowing in the opposite direction. In the coffee water path control connection structure 10, when the first solenoid valve 310 is in the open state, the liquid will flow from the first flow port 3110 to the third flow port 3130, and then the liquid will enter the hot extraction component 300 for heating. Because the third flow port 3130 is a one-way valve, it effectively prevents the heated water from flowing back into the water pump component 100, protecting the water pump component 100 from severe damage.

[0037] like Figure 1As shown, specifically, when the first solenoid valve 310 is in an open state, the third flow port 3130 is connected to the hot extraction component 300, and the second flow port 3120 is in a closed state. It can be understood that by controlling the first solenoid valve 310 to be in an open state, the first flow port 3110 is connected to the hot extraction component 300. At the same time, when the first solenoid valve 310 is in an open state, the second flow port 3120 is in a closed state, so that the second flow port 3120 and the hot and cold extraction switching three-way interface are not connected to each other, ensuring that when the coffee device is in the hot extraction mode, the water source will not flow into the brewing component 200 through the second flow port 3120 for cold water extraction; on the contrary, when the first solenoid valve 310 is in an open state, the water source will enter the first flow port 3110 and then enter the hot extraction component 300 through the third flow port 3130; by controlling the switch state of the first solenoid valve 310, the flow state of the third flow port 3130 and the first flow port 3110 is controlled, thereby changing the working mode of the coffee machine, providing users with flexible and diverse coffee extraction rotation to meet the personalized needs of different users.

[0038] Combine Figure 2 and Figure 3 As shown, further, the coffee water control connection structure 10 also includes a water vapor separation component 400, and the second solenoid valve 320 is also provided with a sixth flow port 3230, and the sixth flow port 3230 is connected to the first port of the water vapor separation three-way interface component 800, and the water vapor separation component 400 is connected to the second port of the water vapor separation three-way interface component 800. It can be understood that because the sixth flow port 3230 of the second solenoid valve 320 is connected to the first port of the water vapor separation three-way interface component 800, when the hot extraction mode is completed, by closing the second solenoid valve 320, the fourth flow port 3210 will be closed, thereby blocking the flow between the hot extraction component 300 and the brewing component 200, and at the same time, the sixth flow port 3230 will be opened, thereby allowing the water vapor generated by the hot extraction component 300 to pass through the sixth flow port 3230 and then flow to the water vapor separation three-way interface component 800. Because the second port of the water vapor separation three-way interface component 800 is connected to the water vapor separation component 400, the water vapor separation component 400 here functions to liquefy the water vapor into condensed water, so that the water vapor generated by the hot extraction component 300 flows into the water vapor separation component 400 through the sixth flow port 3230, and finally forms condensed water and is discharged to the external equipment for recycling.

[0039] like Figure 3As shown, in one embodiment, the coffee waterway control connection structure 10 also includes a coffee steam component 500, an external three-way interface component 40 and a fourth solenoid valve 540, and the coffee steam component 500 includes a steam water pump 510 and a steam boiler 520, the water inlet end of the steam water pump 510 is connected to the first water outlet end of the external three-way interface component 40, the water inlet end of the steam boiler 520 is connected to the water outlet end of the steam water pump 510, and the water vapor separation component 400 is connected to the first port of the fourth solenoid valve 540, and the second port of the fourth solenoid valve 540 is connected to the steam outlet end of the steam boiler 520. It can be understood that by setting the water inlet end of the steam water pump 510 to be connected to the external three-way interface part 40, the steam water pump 510 draws water from the water outlet end of the external three-way interface part 40 into the steam boiler 520, and the water source generates steam in the steam boiler 520. Because the water vapor separation component 400 is connected to the steam boiler 520 through the first port of the fourth solenoid valve 540, when the fourth solenoid valve 540 is controlled to be in an open state, water vapor will enter the water vapor separation box component.

[0040] like Figure 1 As shown, in one embodiment, the water pump assembly 100 also includes a water pump component 110 and a pressure relief exhaust valve 120, the water inlet end of the water pump component 110 is connected to the second water outlet end of the external three-way interface component 40, the water inlet end of the pressure relief exhaust valve 120 is connected to the water outlet end of the water pump component 110, and the water outlet end of the pressure relief exhaust valve 120 is connected to the third port of the water vapor separation three-way interface component 800. It can be understood that the water inlet end of the pressure relief exhaust valve 120 is connected to the water outlet end of the water pump component 110, and because the water inlet end of the water pump component 110 is connected to the second water outlet end of the external three-way interface component 40, when the water pump component 110 draws external water, if the air pressure is greater than or equal to 17 bar, the pressure relief exhaust valve 120 will start at this time, and because the pressure relief exhaust valve 120 is connected to the water vapor separation box assembly through the water vapor separation three-way interface component 800, when the pressure is too high, the air pressure will be discharged into the water vapor separation box assembly through the pressure relief exhaust valve 120, thereby reducing the air pressure of the water pump assembly 100 and stabilizing the operation of the water pump assembly 100.

[0041] Combine Figure 2 and Figure 3As shown, in one embodiment, the coffee steam assembly 500 further includes a steam pipe assembly 530, and the steam outlet end of the fourth solenoid valve 540 is connected to the steam inlet end of the steam pipe assembly 530. It can be understood that the fourth solenoid valve 540 connects the steam boiler 520 and the steam pipe assembly 530. When the fourth solenoid valve 540 is controlled to open, the end of the fourth solenoid valve 540 connected to the steam pipe assembly 530 is in a connected state. When the steam boiler 520 is operating, steam is transmitted into the steam pipe assembly 530 through the solenoid valve connected to the steam inlet end of the steam pipe assembly 530.

[0042] like Figure 1 As shown, specifically, the pressure relief exhaust valve 120 is provided with a first exhaust valve port 1210 and a second exhaust valve port 1220, the first exhaust valve port 1210 is connected to the first circulation port 3110, and the second exhaust valve port 1220 is connected to the water vapor separation assembly 400. It can be understood that because the pressure relief exhaust valve 120 is provided with the first exhaust valve port 1210 and the second exhaust valve port 1220, and the first exhaust valve port 1210 is connected to the first circulation port 3110, when the air pressure of the pressure relief exhaust valve 120 is normal, the liquid enters the first circulation port 3110 through the first exhaust valve port 1210; conversely, when the air pressure to which the pressure relief exhaust valve 120 is subjected is greater than or equal to 17 bar, the pressure of the pressure relief exhaust valve 120 is reduced through the second exhaust valve port 1220.

[0043] Combine Figure 2 and Figure 3 As shown, in one embodiment, the coffee water channel control connection structure 10 further includes a slag discharge assembly 600, a slag discharge three-way interface 900 and a third solenoid valve 630. The slag discharge assembly 600 includes an exhaust pump 610 and a pressure measuring component 620. One port of the third solenoid valve 630 is connected to the exhaust pump 610, and the other port of the third solenoid valve 630 is connected to the first port of the slag discharge three-way interface 900. The second port of the slag discharge three-way interface 900 is connected to the brewing assembly 200. The pressure measuring component 620 is connected to the pressure measuring end of the slag discharge three-way interface 900. It can be understood that because the third solenoid valve 630 is connected to the exhaust pump 610, when the third solenoid valve 630 is opened, the exhaust pump 610 will be connected to the residue discharge three-way interface 900, and at the same time, the exhaust pump 610 will be connected to the brewing component 200 through the residue discharge three-way interface 900, so that when the coffee extraction is completed, the brewing component 200 will be blown by the air provided by the exhaust pump 610, so that the coffee residue left in the brewing component 200 will be blown into the coffee residue storage bucket; at the same time, a pressure measuring piece 620 is installed at the pressure measuring end of the residue discharge three-way interface 900, so that the air pressure provided by the exhaust pump 610 can be observed in real time.

[0044] Combine Figure 3As shown, in one embodiment, the coffee waterway control connection structure 10 further includes an external water tank 20 and a silicone plug 30. The water outlet of the external water tank 20 is connected to the water inlet of the external three-way interface 40, and the silicone plug 30 is disposed on the external three-way interface 40. It can be understood that by connecting the water outlet of the external water tank 20 with the water inlet of the external three-way interface 40, the water in the external water tank 20 flows into the water pump 110 through the external three-way interface 40, and the silicone plug 30 is disposed in the external three-way interface 40. When the external water tank 20 is not used to provide a water source, the silicone plug 30 can be used to seal the external three-way interface 40.

[0045] like Figure 3 As shown, the water pump assembly 100 further includes a flow meter 130, one end of which is connected to the water outlet end of the external three-way interface member 40, and the other end of the flow meter 130 is connected to the water pump member 110. It can be understood that by providing the flow meter 130 at the water outlet end of the external three-way interface member 40 and connecting the other end of the flow meter 130 to the water pump member 110, the pressure of the water provided by the external water tank 20 can be observed through the flow meter 130, thereby noting the working status of the water pump member 110 and the strength of the water extraction.

[0046] A coffee machine includes the coffee water channel control connection structure 10 described in any of the above embodiments. It is understood that by controlling the first solenoid valve 310 and the second solenoid valve 320 to switch between cold brew and hot brew modes, the coffee machine can be freely switched between coffee extraction modes to meet the varying needs of users.

[0047] Compared with the prior art, the present disclosure has at least the following advantages:

[0048] By setting a first solenoid valve 310 and a second solenoid valve 320 in the coffee water path control connection structure 10, and the first solenoid valve 310 is provided with a first flow port 3110, a second flow port 3120 and a third flow port 3130, because the first flow port 3110 is connected to the water outlet end of the water pump assembly 100, when the water pump assembly 100 draws water from the outside, the water source will flow into the first flow port 3110 through the water outlet end of the water pump assembly 100, and at the same time, because the third flow port 3130 is connected to the water inlet end of the hot extraction assembly 300; when hot extraction is performed, the water source will flow from the first flow port 3110 to the third flow port 3130, and at the same time, the second flow port 3120 is closed, so that the water source flows into the hot extraction assembly 300 through the water inlet end of the hot extraction assembly 300 to perform liquid heating extraction processing. After the hot extraction assembly 300 is heated, the water source will pass through the fifth flow port 3130 of the second solenoid valve 320. The water flows from the fourth flow port 3220 to the fourth flow port 3210, and finally flows from the fourth flow port 3210 into the second port of the cold and hot extraction switching three-way interface component 700. Because the port of the cold and hot extraction switching three-way interface component 700 is connected to the brewing component 200, the water source flows into the brewing component 200 for hot extraction of coffee powder; and because the second flow port 3120 is connected to the first port of the cold and hot extraction switching three-way interface component 700, when cold extraction is performed, the water source enters the cold and hot extraction switching three-way interface component 700 through the first flow port 3110 and the second flow port 3120, thereby causing the water source to perform cold water extraction of coffee; by controlling the opening and closing states of the flow ports of the first solenoid valve 310 and the second solenoid valve 320, it is convenient to control the switching between the cold extraction mode and the hot extraction mode of the coffee machine device, so that the extraction mode can be freely switched on the same coffee machine, thereby meeting the different needs of users.
