[0040] In an exemplary embodiment, the powder bowl is used to hold coffee powder. It can be understood that coffee powder needs to be placed in the powder bowl for coffee liquid extraction.

[0041] In an exemplary embodiment, the powder bowl includes a bowl bottom and a bowl wall.

[0042] In an exemplary embodiment, a plurality of through holes are provided in the bowl bottom, that is, the bowl bottom is a mesh structure. The mesh structure is for the coffee liquid to flow out through the through holes in the bowl bottom during subsequent coffee liquid extraction.

[0043] In an exemplary embodiment, the size of the through holes at the bottom of the bowl and the spacing between multiple through holes at the bottom of the bowl can be set according to the particle size of the coffee powder, as long as the extraction requirements of the coffee liquid are met, that is, when the coffee powder is placed in the powder bowl, the coffee powder will not fall off from the bottom of the bowl, or only a very small amount of coffee powder leaks from the bottom of the bowl, and the weight of the leaked coffee powder can be ignored.

[0044] In an exemplary embodiment, the bowl wall is liftable.

[0045] In an exemplary embodiment, when the bowl wall rises from the powder bowl assembly 103, the bowl wall and the bowl bottom together form the powder bowl.

[0046] In an exemplary embodiment, after the bowl wall descends completely, the bowl wall is hidden inside the powder bowl assembly 103; it can be understood that when the bowl wall is completely hidden inside the powder bowl assembly 103, the bowl bottom is exposed on the upper surface of the powder bowl assembly 103; that is, the bowl bottom is flush with the upper surface of the powder bowl assembly 103, or the bowl bottom is slightly higher than the upper surface of the powder bowl assembly 103.

[0047] In an exemplary embodiment, optionally, the bowl wall further includes a heating layer, and the heating layer is used to keep the bowl wall warm and heated, so that the temperature of the coffee liquid can always be maintained in an optimal state, for example, the coffee liquid is maintained at 92°C - 94°C.

[0048] In an exemplary embodiment, the powder bowl assembly 103 further includes: powder bowl through holes.

[0049] In an exemplary embodiment, the powder bowl through holes communicate with the through holes at the bottom of the bowl.

[0057] In an exemplary embodiment, the powder pressing mechanism 108 is disposed on the machine body 101.

[0058] In an exemplary embodiment, the powder pressing mechanism 108 is used to squeeze the coffee powder in the powder bowl.

[0059] In an exemplary embodiment, the powder pressing mechanism 108 is provided with a pressing hammer, and the powder pressing mechanism 108 squeezes the coffee powder in the powder bowl through the pressing hammer.

[0060] In an exemplary embodiment, the shape and size of the pressing hammer are both matched with the powder bowl.

[0061] In an exemplary embodiment, the lower surface of the pressing hammer is smooth and flat. Of course, if necessary, the lower surface of the pressing hammer can also be designed to have a concave-convex shaped surface.

[0062] In an exemplary embodiment, the force of the pressing hammer pressing down is about 15 kilograms.

[0063] In an exemplary embodiment, the purpose of compacting the coffee powder in the powder bowl is to flatten the coffee powder and squeeze the coffee powder into a cake shape; it can be understood that when finally extracting coffee liquid, it is the coffee cake that is extracted, rather than directly extracting the loose coffee powder.

[0064] In an exemplary embodiment, squeezing the coffee powder into a cake shape is to obtain a better extraction effect.

[0065] In an exemplary embodiment, the coffee liquid extraction device of the embodiment of the present application further includes: an extraction head.

[0066] In an exemplary embodiment, the extraction head is disposed on the side of the powder pressing mechanism 108, for example, on the left or right side of the powder pressing mechanism 108.

[0067] In an exemplary embodiment, the extraction head is disposed on the machine body 101.

[0068] In an exemplary embodiment, the extraction head is used to extract the coffee powder in the powder bowl after being squeezed, that is, to extract the coffee cake.

[0069] In an exemplary embodiment, according to needs, the extraction head is externally connected to a water pipeline, and the water pipeline is connected to a hot water pipeline or a cold water pipeline.

[0070] In an exemplary embodiment, the extraction head is used to extract the coffee powder in the powder bowl that has been squeezed and is located directly below the extraction head.

[0071] In an exemplary embodiment, the water outlet of the extraction head is in the shape of a shower head or a net.

[0072] In an exemplary embodiment, there is at least one extraction head, and of course, according to needs, there can be multiple extraction heads.

[0073] In an exemplary embodiment, the number of extraction heads is even, for example, there are two extraction heads.

[0074] In an exemplary embodiment, the number of extraction heads is the same as the number of powder bowls.

[0075] In an exemplary embodiment, the number of extraction heads is even, and the even-numbered extraction heads are symmetrically arranged on both sides of the powder pressing mechanism 108.

[0076] In an exemplary embodiment, for example, there are two extraction heads and two powder bowls.

[0077] In an exemplary embodiment, the line connecting the center points of the first powder bowl 104 and the second powder bowl 105 is parallel to the line connecting the center points of the two extraction heads.

[0078] In an exemplary embodiment, the two extraction heads are arranged on both sides of the powder pressing mechanism 108 at equal intervals.

[0079] In an exemplary embodiment, the distance between the center points of the two powder bowls is equal to the distance from the center point of the extraction head to the center point of the powder pressing mechanism 108. For example, the distance between the center point of the first powder bowl 104 and the center point of the second powder bowl 105 is equal to the distance from the center point of the first extraction head 106 to the center point of the powder pressing mechanism 108.

[0080] In an exemplary embodiment, the coffee liquid extraction device of the embodiment of the present application further includes a pushing mechanism.

[0081] In an exemplary embodiment, the pushing mechanism is arranged below the powder pressing mechanism 108.

[0082] In an exemplary embodiment, the pushing mechanism is arranged on the machine body 101.

[0083] In an exemplary embodiment, the pushing mechanism is used to send coffee powder into the powder bowl located below the powder pressing mechanism 108.

[0084] In an exemplary embodiment, the pushing mechanism further includes a part for pushing off the coffee powder residue on the bottom of the bowl.

[0085] In an exemplary embodiment, for example, when the currently idle powder bowl is the first powder bowl 104, the first powder bowl 104 after raising the bowl wall moves below the powder pressing mechanism 108. The pushing mechanism feeds coffee powder of a corresponding weight into the first powder bowl 104. Then, the powder pressing mechanism 108 presses the coffee powder in the first powder bowl 104 into a powder cake. Finally, the first powder bowl 104 moves below the idle extraction head. For example, the first powder bowl 104 moves below the first extraction head 106, and the first extraction head 106 extracts coffee liquid from the first powder bowl 104. After the coffee liquid extraction work in the first powder bowl 104 is completed, the first powder bowl 104 moves below the powder pressing mechanism 108, and the bowl wall of the first powder bowl 104 descends, exposing the coffee residue on the bottom of the bowl. The pushing mechanism pushes the coffee residue on the bottom of the bowl off the bottom of the bowl, and the coffee residue after being pushed off falls into the residue storage tank 111.

[0086] In an exemplary embodiment, when all the current powder bowls are in a working state, for example, the first powder bowl 104 is extracting coffee liquid below the first extraction head 106, and the second powder bowl 105 contains coffee residue and is exactly located below the powder pressing mechanism 108. At this time, the bowl wall of the second powder bowl 105 descends, and the pushing mechanism pushes the coffee residue on the bottom of the second powder bowl 105 off. According to needs, the second powder bowl 105 can continue to hold coffee powder of a corresponding weight and be squeezed by the powder pressing mechanism 108. Or when there is no new coffee liquid extraction instruction and after the coffee liquid extraction in the first powder bowl 104 is completed, the powder bowl assembly 103 moves, the first powder bowl 104 moves below the powder pressing mechanism 108, and the second powder bowl 105 synchronously moves below the second extraction head 107. At this time, the above steps of pushing the coffee residue off the bottom of the bowl are repeated.

[0087] In an exemplary embodiment, after the coffee residue is pushed off the bottom of the bowl by the pushing mechanism, if there is a coffee liquid extraction instruction that needs to be continued, the bowl wall rises again, the pushing mechanism repeats the step of pushing the coffee powder, and the powder pressing mechanism 108 repeats the step of pressing the coffee powder.

[0088] In an exemplary embodiment, the design of the above double powder bowls and double extraction heads realizes the synchronization of powder pressing and extraction as well as the synchronization of extraction and residue removal, greatly saving the time for coffee liquid extraction and preparation.

[0089] In an exemplary embodiment, there are also through holes provided on the workbench 102.

[0090] In an exemplary embodiment, the through holes are located below the extraction head, for example, directly below the extraction head.

[0091] In an exemplary embodiment, optionally, on the workbench 102, through holes are provided directly below both the first extraction head 106 and the second extraction head 107.

[0092] In an exemplary embodiment, of course, according to requirements, there may also be only one through hole. When there is only one through hole, a groove is provided on the workbench 102. The groove is, for example, provided between two guide rails 109. The length of the groove does not exceed the length of the guide rails 109, and the through hole is provided in the groove.

[0093] In an exemplary embodiment, the groove is connected to the through hole. The coffee liquid after extraction from the powder bowl enters the groove and then flows out through the through hole on the workbench 102.

[0094] In an exemplary embodiment, when the powder bowl moves to directly below the extraction head, the powder bowl through hole is connected to the through hole on the workbench 102. For example, when through holes are provided directly below both the first extraction head 106 and the second extraction head 107, when the first powder bowl 104 moves to below the first extraction head 106, the powder bowl through hole below the first powder bowl 104 is connected to the through hole on the workbench 102. When the first extraction head 106 extracts the coffee powder cake located in the first powder bowl 104, the extracted coffee liquid flows out through the through hole on the workbench 102, or it can be understood that the user finally obtains the coffee liquid through the through hole on the workbench 102.

[0095] In an exemplary embodiment, when there is only one through hole on the workbench 102, taking the cooperation between the first extraction head 106 and the first powder bowl 104 to extract coffee liquid as an example, the first extraction head 106 extracts the coffee liquid from the coffee powder cake in the first powder bowl 104. The coffee liquid flows into the groove on the workbench 102 through the powder bowl through hole and then flows out through the through hole connected to the groove.

[0096] In an exemplary embodiment, optionally, a slag storage tank 111 is further included below the machine body 101. The slag storage tank 111 is located in front of the powder pressing mechanism 108, that is, when the coffee residue is pushed off from the bottom of the bowl, it falls into the slag storage tank 111.

[0097] In an exemplary embodiment, the slag storage tank 111 is located below the workbench 102.

[0098] In an exemplary embodiment, optionally, the slag storage tank 111 can also be used to receive the falling waste liquid.
