[0002] A coffee machine is a device used to make coffee. It can help users easily make different kinds of coffee at home or in commercial places. With the popularization of coffee culture, the types and functions of coffee machines have become more and more diverse. Existing coffee machines are divided into manual coffee machines, semi-automatic coffee machines and fully automatic coffee machines.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] It should be noted that when a component or structure is referred to as being "fixed to" or "disposed on" another component or structure, it may be directly on the other component or structure or indirectly on the other component or structure. When a component or structure is referred to as being "connected to" another component or structure, it may be directly connected to the other component or structure or indirectly connected to the other component or structure.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] In the existing coffee machines, there is a solution of controlling the movement of the coffee machine by a rocker lever instead of a cam. When the coffee machine is controlled by a rocker lever, it is easy to cause the parts of the coffee machine to operate unstably, resulting in an unstable working process of the coffee machine and prone to failure.

[0032] Based on the above reasons, the embodiment of the present application provides an extraction cylinder structure, which includes an extraction cylinder assembly, and the extraction cylinder assembly includes an extraction cylinder, a sealing push plate, a push rod, a roller and a push rod spring, wherein the sealing push plate is movably arranged in the extraction cylinder, the first end of the push rod is connected to the sealing push plate, the roller is rotatably connected to the second end of the push rod, and the push rod spring is arranged outside the extraction cylinder and is used to support the push rod and the sealing push plate to reset. The extraction cylinder structure in the embodiment of the present application guides the extraction cylinder assembly through the roller, and the roller can push the push rod to drive the sealing push plate to move in the extraction cylinder while guiding, and the sealing push plate moves in the extraction cylinder to realize the function of pushing out the coffee grounds cake, which can improve the stability of the coffee machine during the extraction process.

[0033] In some scenarios, an extraction cartridge structure of an embodiment of the present application can be applied to a coffee machine, specifically to a coffee extraction structure of the coffee machine, and can improve the stability of the extraction structure of the coffee machine.

[0034] The following is a detailed description of an extraction cartridge structure provided in an embodiment of the present application with reference to specific examples.

[0035] Figure 1 This is a three-dimensional structural schematic diagram of an extraction cartridge structure provided in an embodiment of the present application. Figure 2 A schematic diagram of the internal structure of an extraction cartridge structure provided in an embodiment of the present application is shown in FIG. Figure 1 and Figure 2 As shown, the extraction cylinder structure includes an extraction cylinder assembly 4, which includes an extraction cylinder 41, a sealing push plate 42, a push rod 43, a roller 44 and a push rod spring 45. The sealing push plate 42 is movably arranged in the extraction cylinder 41, the first end of the push rod 43 is connected to the sealing push plate 42, the roller 44 is rotatably connected to the second end of the push rod 43, and the push rod spring 45 is arranged on the outside of the extraction cylinder 41 and is used to support the push rod 43 and the sealing push plate 42 to reset.

[0036] like Figure 1 and Figure 2 As shown, structurally, the extraction cylinder structure includes an extraction cylinder assembly 4, which is a working assembly for extracting coffee. The extraction cylinder assembly 4 includes an extraction cylinder 41, a sealing push plate 42, a push rod 43, a roller 44 and a push rod spring 45. The extraction cylinder 41 is a container for extracting coffee, the sealing push plate 42 is used to squeeze coffee powder when extracting coffee, and the push rod 43 is used to push the sealing push plate 42 to squeeze the coffee powder, and can also push the sealing push plate 42 to eject the coffee grounds cake.

[0037] Structurally, one end of the extraction cylinder 41 may be an open structure, and coffee powder can be loaded into the extraction cylinder 41 through the opening structure of the extraction cylinder 41.

[0038] When in use, the roller 44 can cooperate with the guide structure of the coffee machine to guide the extraction cartridge structure. Figure 2 As shown, the roller 44 can cooperate with the baffle 12 to guide the extraction cartridge structure.

[0039] like Figure 2 As shown, the sealing push plate 42 is movably disposed in the extraction cylinder 41 , so that the sealing push plate 42 can squeeze the coffee powder in the extraction cylinder 41 or push the coffee grounds cake out of the extraction cylinder 41 .

[0040] like Figure 2 As shown, the roller 44 is rotatably connected to the second end of the push rod 43, so that the roller 44 can guide the movement of the push rod 43 on the push rod 43, and the roller 44 can also push the push rod 43 to drive the sealing push plate 42 to move in the extraction cylinder 41 when squeezed.

[0041] Structurally, the first end of the push rod 43 is connected to the sealing push plate 42, and the push rod spring 45 is arranged on the outside of the extraction cylinder 41 and is used to support the push rod 43 and the sealing push plate 42 to reset, so that after the push rod 43 pushes the sealing push plate 42 to move along the extraction cylinder 41, the push rod spring 45 can push the sealing push plate 42 to move in the opposite direction inside the extraction cylinder 41 to reset.

[0042] Figure 3 A schematic diagram of the structure of an extraction cartridge provided in an embodiment of the present application in a first state, as shown in FIG. Figure 3 As shown, the extraction cartridge structure moves along the guide rail on the frame 1 of the coffee machine. At this time, the roller 44 is not in contact with the baffle 12, so that the roller 44 is not squeezed by the baffle 12, and the push rod spring 45 supports the push rod 43 and the sealing push plate 42 to be in a reset state.

[0043] Figure 4 A schematic diagram of the structure of an extraction cartridge provided in an embodiment of the present application in a second state, as shown in FIG. Figure 4 As shown, the extraction cylinder structure continues to move along the guide rail on the frame 1 of the coffee machine. At this time, the roller 44 is in contact with the baffle 12, and the baffle 12 guides the roller 44, so that the baffle 12 can guide the extraction cylinder structure through the roller 44; at the same time, the roller 44 is squeezed by the baffle 12, and the push rod spring 45 supports the push rod 43 and the sealing push plate 42 to push the coffee grounds cake out of the extraction cylinder 41.

[0044] like Figure 2 As shown, the direction in which the sealing push plate 42 pushes the coffee grounds cake out of the extraction cylinder 41 is Figure 2 The direction of the arrow.

[0045] Figure 5 A schematic diagram of the structure of an extraction cartridge provided in an embodiment of the present application in a third state, as shown in FIG. Figure 5As shown, when the extraction cylinder structure continues to move along the guide rail on the frame 1 of the coffee machine, the baffle 12 guides the roller 44, so that the extraction cylinder structure can rotate on the coffee machine, thereby facilitating the loading of coffee powder into the extraction cylinder 41; at the same time, the push rod spring 45 supports the push rod 43 and the sealing push plate 42, so that the push rod 43 and the sealing push plate 42 are in a reset state.

[0046] When the extraction cartridge structure moves in the reverse direction along the guide rail of the coffee machine, the baffle plate 12 can guide the extraction cartridge structure through the roller 44 .

[0047] The beneficial effect brought about by the above implementation method is that the extraction cartridge structure is guided by the roller, which improves the stability of the extraction cartridge structure when working in the coffee machine and improves the use effect of the coffee machine.

[0048] The beneficial effect brought about by the above-mentioned implementation method is that while the roller guides the extraction cylinder structure, it can push the sealing push plate to eject the coffee grounds cake in the extraction cylinder, and the ejector spring can push the sealing push plate to move in the opposite direction and reset in the extraction cylinder, thereby facilitating the cleaning of the coffee grounds cake.

[0049] In some implementations, a push rod limiting hole 412 is provided on the extraction cylinder 41, and a push rod clamping groove 431 is provided on one end of the push rod 43 near the sealing push plate 42. A push rod limiting spring 413 and a push rod limiting boss 414 are provided in the push rod limiting hole 412. The push rod limiting spring 413 and the push rod limiting boss 414 are abutted against each other, and the push rod limiting boss 414 can be inserted into the push rod clamping groove 431 or slide out of the push rod clamping groove 431.

[0050] Figure 6 This is a schematic diagram of the cross-sectional structure of an extraction cartridge structure provided in an embodiment of the present application during coffee extraction. Figure 7 for Figure 6 A schematic diagram of the local structure of an extraction cartridge structure at A, as shown in Figure 6 and Figure 7 As shown, the extraction cylinder 41 is provided with a push rod limiting hole 412 , and the push rod limiting hole 412 is used to install a limiting structure for limiting the push rod 43 .

[0051] Structurally, a push rod clamping groove 431 is provided on one end of the push rod 43 close to the sealing push plate 42 , and the push rod clamping groove 431 is used to cooperate with the locking structure of the push rod 43 to limit the push rod 43 .

[0052] like Figure 6 and Figure 7As shown, a push rod limiting spring 413 and a push rod limiting boss 414 are provided in the push rod limiting hole 412. The push rod limiting spring 413 and the push rod limiting boss 414 are in abutment with each other, so that the push rod limiting spring 413 can support the push rod limiting boss 414 in the push rod slot 431. The push rod limiting boss 414 can be inserted into the push rod slot 431 or slide out of the push rod slot 431, so as to limit the push rod 43 to a certain extent.

[0053] When the push rod limiting boss 414 is inserted into the push rod slot 431, the push rod limiting boss 414 can be engaged in the push rod slot 431 to limit the axial movement of the push rod 43, so that the push rod 43 and the sealing push plate 42 can be stably positioned in the extraction cylinder 41 when the extraction cylinder 41 rotates, and after the coffee powder is connected to the extraction cylinder 41, the coffee powder in the extraction cylinder 41 can be prevented from spilling out of the extraction cylinder 41.

[0054] When the push rod limiting protrusion 414 slides out from the push rod slot 431 , the push rod 43 can overcome the limiting force of the push rod limiting protrusion 414 , thereby pushing the sealing push plate 42 to push the coffee grounds cake out of the extraction cylinder 41 .

[0055] The beneficial effect brought about by the above-mentioned implementation method is that the push rod limiting boss limits the axial movement of the push rod, thereby limiting the sliding of the sealing push plate in the extraction cylinder, and preventing the coffee powder in the extraction cylinder from spilling out of the extraction cylinder after the coffee powder is connected to the extraction cylinder.

[0056] In some implementations, a boss adjustment nut 415 is threadedly connected to the push rod limiting hole 412 , and the pressure of the push rod limiting spring 413 on the push rod limiting boss 414 can be adjusted by adjusting the boss adjustment nut 415 .

[0057] like Figure 7 As shown, a boss adjusting nut 415 is threadedly connected in the push rod limiting hole 412. When the boss adjusting nut 415 is rotated, the position of the boss adjusting nut 415 in the push rod limiting hole 412 can be adjusted. When the boss adjusting nut 415 moves axially in the push rod limiting hole 412, the compression degree of the push rod limiting spring 413 can be adjusted, so that adjusting the boss adjusting nut 415 can adjust the pressure of the push rod limiting spring 413 on the push rod limiting boss 414.

[0058] When the extraction cylinder structure is working, when the roller 44 rotates, the roller 44 applies pressure to the ejector rod 43, and the ejector rod 43 and the baffle 12 squeeze each other to make the ejector rod 43 move axially. By adjusting the pressure of the ejector rod limiting spring 413 on the ejector rod limiting boss 414, the pressure between the ejector rod limiting boss 414 and the ejector rod slot 431 is adjusted, so that the ejector rod 43 can move relative to the extraction cylinder 41 only under the action of a certain axial force, thereby realizing the adjustment of the thrust threshold of the ejector rod 43 when pushing the sealing push plate 42 to move in the extraction cylinder 41, and controlling the timing of the sealing push plate 42 to eject the coffee grounds cake.

[0059] The beneficial effect brought about by the above-mentioned implementation method is that it can adjust the thrust threshold of the push rod pushing the sealing push plate when the extraction cylinder moves, and then can control the timing of the sealing push plate to eject the coffee grounds cake, thereby improving the use effect of the coffee machine.

[0060] In some implementations, a one-way valve 421 is provided on the sealing push plate 42, and an extraction cylinder water outlet pipe 411 for docking with the one-way valve 421 is provided on the side wall of the extraction cylinder 41. When the extraction cylinder assembly 4 and the sealing push plate 42 reach the extraction position, the water outlet of the one-way valve 421 is connected to the extraction cylinder water outlet pipe 411.

[0061] like Figure 7 As shown, a one-way valve 421 is provided on the sealing push plate 42, and the one-way valve 421 is used to control the one-way flow of the extracted coffee liquid, thereby avoiding the backflow of the coffee liquid and ensuring the quality of the coffee liquid.

[0062] like Figure 7 As shown, an extraction tube water outlet pipe 411 for docking with a one-way valve 421 is provided on the side wall of the extraction tube 41, and the extraction tube water outlet pipe 411 is used to output the coffee liquid extracted by the extraction structure.

[0063] like Figure 6 and Figure 7 As shown, when the extraction cylinder assembly 4 and the sealing push plate 42 reach the extraction position, the water outlet of the one-way valve 421 is connected to the extraction cylinder water outlet pipe 411, so that the one-way valve 421 can discharge the extracted coffee liquid through the extraction cylinder water outlet pipe 411, thereby realizing the delivery of the extracted coffee liquid.

[0064] like Figure 7 As shown, a filter screen is provided on the sealing push plate 42, and the filter screen can filter the coffee liquid.

[0065] The beneficial effect brought about by the above-mentioned implementation method is that the one-way valve can control the one-way flow of the extracted coffee liquid, avoid the backflow of the coffee liquid, and ensure the quality of the extracted coffee liquid.

[0066] In some implementations, a valve hole 422 is provided on the sealing push plate 42, and the one-way valve 421 includes a valve head 421a, a valve head spring 421b and a valve head adjusting nut 421c. The valve head 421a and the valve head spring 421b are provided in the valve hole 422, and the valve head adjusting nut 421c is threadedly connected in the valve hole 422. By adjusting the valve head adjusting nut 421c, the pressure of the valve head spring 421b on the valve head 421a can be adjusted.

[0067] like Figure 7 As shown, the sealing push plate 42 is provided with a valve hole 422 , the valve hole 422 is used to install a one-way valve 421 , and the valve head 421 a is a switch working structure of the one-way valve 421 .

[0068] like Figure 7 As shown, the one-way valve 421 includes a valve head 421a, a valve head spring 421b and a valve head adjusting nut 421c. The valve head 421a and the valve head spring 421b are arranged in the valve hole 422. The valve head spring 421b squeezes the valve head 421a. The valve head spring 421b is used to provide a restoring force for the one-way valve 421. When coffee liquid enters the one-way valve 421 from the sealing push plate 42, the coffee liquid squeezes the valve head 421a, so that the valve head spring 421b is compressed, and the valve head 421a can give way to allow the coffee liquid to be discharged through the one-way valve 421.

[0069] Structurally, the valve head adjusting nut 421c is threadedly connected in the valve hole 422, and the position of the valve head adjusting nut 421c in the valve hole 422 can be adjusted by rotating the valve head adjusting nut 421c. When adjusting the position of the valve head adjusting nut 421c in the valve hole 422, the pressure of the valve head spring 421b on the valve head 421a can be adjusted, and the pressure threshold of the coffee liquid passing through the valve head 421a can be adjusted, thereby realizing the adjustment of the extraction pressure of the coffee liquid.

[0070] The beneficial effect brought about by the above implementation method is that the coffee liquid can only flow through the one-way valve in one direction, thereby achieving one-way flow control of the coffee liquid and ensuring the extraction quality of the coffee liquid.

[0071] The beneficial effect brought about by the above implementation method is that the pressure threshold of the coffee liquid passing through the valve head can be adjusted, thereby achieving the adjustment of the extraction pressure of the coffee liquid.

[0072] In some implementations, the extraction cartridge structure further includes an extraction cartridge support assembly 3 , the extraction cartridge assembly 4 is disposed on the extraction cartridge support assembly 3 , and the extraction cartridge support assembly 3 is provided with a guide protrusion 31 for guiding the extraction cartridge support assembly 3 .

[0073] like Figure 1As shown, the extraction cartridge structure further includes an extraction cartridge support assembly 3 , which is used to fix the extraction cartridge assembly 4 , and the extraction cartridge assembly 4 is disposed on the extraction cartridge support assembly 3 .

[0074] like Figure 1 As shown, a guide convex rod 31 for guiding the extraction cylinder bracket assembly 3 is provided on the extraction cylinder bracket assembly 3. When the extraction cylinder bracket assembly 3 moves on the frame 1, the extraction cylinder bracket assembly 3 can be guided by the guide convex rod 31, so that the extraction cylinder bracket assembly 3 can move along a predetermined trajectory together with the extraction cylinder assembly 4, thereby achieving control accuracy of the movement process of the extraction cylinder bracket assembly 3 and the extraction cylinder assembly 4.

[0075] The beneficial effect brought about by the above implementation method is that the extraction cylinder support assembly can move along a predetermined trajectory together with the extraction cylinder assembly, and the guiding effect of the top rod and the roller is combined to achieve the control accuracy of the movement process of the extraction cylinder support assembly and the extraction cylinder assembly.

[0076] In some implementations, the extraction cartridge support assembly 3 is provided with an extraction cartridge support bypass 301 that is connected to the extraction cartridge water outlet pipe 411, and the extraction cartridge support bypass 301 is used to output finished coffee.

[0077] like Figure 1 As shown, the extraction cartridge support assembly 3 is provided with an extraction cartridge support bypass 301 which is connected to the extraction cartridge water outlet pipe 411. The extraction cartridge support bypass 301 is used to output finished coffee, so that the extraction cartridge support bypass 301 can be integrated on the extraction cartridge support assembly 3, thereby reducing the volume of the extraction cartridge support assembly 3 and improving the use effect of the coffee machine.

[0078] The beneficial effect brought about by the above-mentioned implementation method is that the extraction cartridge support bypass for conveying coffee liquid can be integrated on the extraction cartridge support assembly, thereby reducing the volume of the extraction cartridge support assembly and improving the use effect of the coffee machine.

[0079] In some implementations, a slider positioning hole 302 is provided on the extraction tube support assembly 3, and the extraction tube support bypass 301 includes a bypass groove 301a and a bypass pipe 301b. The bypass groove 301a is opened on the extraction tube support assembly 3, and the bypass groove 301a is arranged around the slider positioning hole 302. The bypass pipe 301b is arranged in the bypass groove 301a, and one end of the bypass pipe 301b is connected to the extraction tube water outlet pipe 411.

[0080] Figure 8 A schematic diagram of a three-dimensional exploded structure of an extraction cartridge support assembly provided in an embodiment of the present application is shown in FIG. Figure 8As shown, the extraction cartridge support assembly 3 is provided with a slider positioning hole 302, which is used to cooperate with the slider 23 of the coffee machine to position the extraction cartridge support assembly 3, and the slider 23 is used to drive the extraction cartridge support assembly 3 to move. During operation, the slider positioning hole 302 is sleeved and connected to the slider 23, so that the extraction cartridge support assembly 3 can move along the slider 23.

[0081] like Figure 1 and Figure 8 As shown, the extraction cartridge support bypass 301 includes a bypass groove 301a and a bypass pipe 301b. The bypass groove 301a is provided on the extraction cartridge support assembly 3. The bypass groove 301a is used to fix the bypass pipe 301b.

[0086] like Figure 1 and Figure 8 As shown, structurally, the extraction cartridge support assembly 3 is further provided with a bypass connector 81, and the bypass connector 81 is used to transport the coffee liquid output by the extraction cartridge support assembly 3 to other pipelines.

[0087] like Figure 1 As shown, the bypass joint 81 is provided with an annular bypass joint sleeve 811, and the bypass joint 81 is connected to the bypass pipe 301b, so that the bypass joint sleeve 811 can discharge the coffee liquid in the bypass joint 81.

[0088] Structurally, the bypass joint sleeve 811 is annular and can be socketed and connected to the coffee delivery pipe of the coffee machine. The water outlet of the bypass joint sleeve 811 is arranged on the inner wall of the bypass joint sleeve 811, so that when the bypass joint sleeve 811 and the coffee delivery pipe are matched, coffee can be delivered to the delivery pipe of the coffee machine through the water outlet on the inner wall of the bypass joint sleeve 811, thereby improving the convenience of the extraction cartridge bracket assembly 3 in delivering coffee.

[0089] The beneficial effect brought about by the above implementation is that the coffee liquid in the extraction cartridge support assembly can be easily transported to the external coffee pipeline through the bypass joint.

[0090] The beneficial effect brought about by the above implementation method is that the coffee is delivered to the delivery pipe of the coffee machine through the water outlet on the inner wall of the bypass joint sleeve, which improves the convenience of the extraction cartridge bracket assembly in delivering coffee.

[0091] The embodiment of the present application also provides a coffee machine, which includes the extraction cartridge structure described in any one of the above items. When the coffee machine is in use, the extraction cartridge structure guides the extraction cartridge assembly through the roller, and the roller can push the ejector rod to drive the sealing push plate to move in the extraction cartridge while guiding, and the sealing push plate moves in the extraction cartridge to push out the coffee grounds, thereby improving the stability of the coffee machine during the extraction process.

[0092] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
