When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0034] See also Figures 1 to 5 The utility model provides a brewing module, which is mainly used in beverage preparation equipment. It can be understood that the beverage preparation equipment can be any preparation equipment that prepares raw materials into beverages in any way, and can be but not limited to fully automatic or semi-automatic coffee machines, soybean milk machines, food processors, etc.
[0035] Taking the coffee machine as an example, the brewing module includes a brewing cylinder 100, a first piston 210 and a second piston 310. The brewing cylinder 100 is provided with a channel 110 along a first direction, and the channel 110 is formed with a first port 111 and a second port 112; the first piston 210 is movably arranged outside the channel 110, and can move closer to and away from the first port 111; the second piston 310 is movably arranged inside the channel 110 along the first direction, and can move closer to and away from the first port 111; wherein, when both the first piston 210 and the second piston 310 move closer to the first port 111, the powder received by the second piston 310 is pressed into a powder cake.
[0036] In the technical solution provided by the utility model, the first piston member 210 moves outside the channel 110, wherein, when a brewing stroke is required, the first piston member 210 only needs to move close to the first port 111, and the second piston member 310 simultaneously moves close to the first port 111, that is, the powder material at the second piston member 310 can be pressed and extracted, greatly shortening the displacement distance of the first piston member 210; and then, when a slag discharge stroke is required, such as operating the transfer of the brewing cylinder 100, the first piston member 210 also only needs to move away from the first port 111, which can eliminate the obstruction to the movement of the brewing cylinder 100 or the movement of the second piston member 310, and also greatly shorten the reset distance of the first piston member 210. The utility model helps to simplify the movement of the first piston member 210, thereby simplifying the structure of the first piston member 210 and its driving mechanism, shortening the execution time, and ultimately helping to improve the brewing efficiency of the brewing module.
[0037] It should be noted that the present design does not restrict the first direction. When the brewing module is installed in the housing of the beverage preparation device, the first direction is suitable for specific adjustment of the installation orientation of the brewing module. For example, when the brewing cylinder 100 in the brewing module is arranged to extend approximately along the vertical direction, the first direction is also the vertical direction. The brewing cylinder 100 has an upper end and a lower end located in the vertical direction. Among them, the first port 111 is opened at the upper port of the brewing cylinder 100, and the second port 112 is opened at the lower port of the brewing cylinder 100.
[0038] The first piston member 210 mainly moves outside the channel 110. It should be noted that the movement direction and movement form of the first piston member 210 are not limited. According to actual needs, the first piston member 210 can be translated along the vertical direction, or can be translated or rotated along other directions. The same reference position of the first piston member 210 has two extreme positions A0 and A1 located on its own movement stroke. Take the lower end surface of the first piston member 210 as an example of the reference position, where A0 is the extreme position when the first piston member 210 moves away from the first port 111. When in the A0 position, the first piston member 210 is sufficiently away from the brewing cylinder 100, so that the movement of the brewing cylinder 100 itself and the movement of other components from the first port 111 into the channel 110 will not be interfered by the first piston member 210. A1 is the extreme position when the first piston member 210 moves close to the first port 111. When in the A1 position, the first piston member 210 is sufficiently close to the first port 111.
[0039] According to actual needs, the position A1 may be a position where the lower end surface of the first piston member 210 is flush with the plane where the first port 111 is located. That is, at this time, the first piston member 210 is outside the channel 110, but just covers the first port 111. In this embodiment, the outer diameter of the first piston member 210 is not less than the caliber setting of the first port 111. Specifically, the area of at least the lower end surface of the first piston member 210 is the same as the area of the first port 111, or the area of at least the lower end surface of the first piston member 210 is larger than the area of the first port 111, so that at least the lower end surface of the first piston member 210 completely covers the first port 111, and no gap is formed between the first piston member 210 and the first port 111.
[0040] Alternatively, the position A1 may be located in the channel 110 near the first port 111. That is, at this time, the main body of the first piston member 210 is outside the channel 110, but at least the lower end surface of the first piston member 210 extends into the channel 110, and the first piston member 210 as a whole blocks the first port 111. In this embodiment, the outer diameter of the first piston member 210 and the inner diameter of the channel 110 are matched. Specifically, the cross-sectional area of at least the portion of the first piston member 210 extending into the channel 110 is substantially the same as the cross-sectional area of the channel 110 at the location, so that no gap is formed between the first piston member 210 and the channel 110.
[0041] When the first piston 210 moves to the A1 position, it stops and does not continue to move in the channel 110 toward the second port 112 .
[0042] The second piston member 310 mainly moves in the channel 110. The second piston member 310 performs translational movement roughly along the vertical direction. The same reference position of the second piston member 310 has two extreme positions B0 and B1 located on its own movement stroke. Taking the upper end surface of the second piston member 310 as an example of a reference position, B0 is the extreme position when the second piston member 310 moves away from the first port 111 and moves close to the second port 112. When in the B0 position, the second piston member 310 is sufficiently away from the first port 111, so that the receiving volume of the channel 110 can be expanded, so that the channel 110 can receive more required powder. B1 is the extreme position when the second piston member 310 moves close to the first port 111.
[0043] The outer diameter of the second piston member 310 is set to match the inner diameter of the channel 110. That is, the cross-sectional area of at least a certain part of the second piston member 310 is substantially the same as the cross-sectional area of the channel 110 at that location, so that no gap is formed between the second piston member 310 and the channel 110.
[0044] In view of the above, in actual application, the brewing cylinder 100 together with the second piston member 310 may have a displacement stroke in the lateral direction as a whole, and have a powder receiving position and a brewing position. The brewing position is a position sufficiently close to the first piston member 210. The powder receiving position is a position sufficiently far away from the first piston member 210 but sufficiently close to the powder supply module.
[0045] When the brewing cylinder 100 and the second piston 310 are in the powder receiving position, the first port 111 of the channel 110 is open, and the second piston 310 is just in the B0 position or in a position close to B0, so that enough space can be reserved in the channel 110 to facilitate the receiving of the powder discharged by the powder supply module. The powder supply module can be a grinding module, a powder storage module, etc.
[0046] Then, when the brewing cylinder 100 and the second piston 310 move to the brewing position with the powder material received, the first piston 210 is first in the A0 position. At this time, firstly, the second piston 310 can reciprocate in a certain period in the vertical direction, which helps to shake and flatten the powder material received by the second piston 310 and accumulated in a cone shape. Then, the first piston 210 moves to the A1 position and the second piston 310 moves to the B1 position, and the two are sufficiently close to each other, so that the powder material received by the second piston 310 can be pressed into a powder cake.
[0047] It should be noted that the operation sequence of the first piston member 210 moving to the A1 position and the second piston member 310 moving to the B1 position is not limited: the first piston member 210 may be first operated to move from the A0 position to the A1 position and then stop, and then the second piston member 310 may be switched to move from the B0 position to the B1 position. Alternatively, the second piston member 310 may be first operated to move from the B0 position to the B1 position and then stop, and then the first piston member 210 may be switched to move from the A0 position to the A1 position. Of course, the first piston member 210 may be operated to move from the A0 position to the A1 position and the second piston member 310 may be operated to move from the B0 position to the B1 position at the same time.
[0048] Finally, the brewing module also includes a liquid supply component, which can connect hot water to the brewing chamber to brew the powder cake in the brewing chamber into coffee liquid.
[0049] It should be noted that, since the first piston member 210 and the second piston member 310 are movable respectively, in specific applications, the brewing module further includes a first driving mechanism 220 and a second driving mechanism 320, wherein the first driving mechanism 220 is driven to connect the first piston member 210, and the second driving mechanism 320 is driven to connect the second piston member 310. The first piston member 210's movement start and stop, movement direction, movement speed, etc. are all driven by the first driving mechanism 220; the second piston member 310's movement start and stop, movement direction, movement speed, etc. are all driven by the second driving mechanism 320. The specific schemes of the first driving mechanism 220 and the second driving mechanism 320 are not limited, and may only include a driver such as a linear cylinder, or may be a combination of a driver such as a motor, a linear cylinder, and a transmission assembly. The transmission assembly may be, but is not limited to, a reversing transmission assembly, a variable speed transmission assembly, etc., such as a gear set, a gear rack mechanism, a screw nut mechanism, a belt transmission mechanism, etc.
[0050] Under the drive of the first driving mechanism 220 and the second driving mechanism 320, the motion state and stop timing of the first piston member 210 and the second piston member 310 can be adjusted, so that the above-mentioned A0 position, A1 position, B0 position and B1 position can be adjusted respectively. In actual application, the first piston member 210 has a first position (i.e., A1 position) when it moves close to the first port 111, and the second piston member 310 has a second position (i.e., B1 position) when it moves close to the first port 111. The distance between the A1 position and the B1 position is not greater than the target thickness of the powder. The target thickness of the powder can be adjusted according to actual needs, so the distance between the A1 position and the B1 position can also be adaptively adjusted.
[0051] Of course, the movement sequence of the first piston member 210 and the second piston member 310 mentioned above can also be achieved by controlling the first driving mechanism 220 and the second driving mechanism 320 respectively.
[0052] In the above embodiment, the first piston member 210 stops at the A1 position when it is sufficiently close to the first port 111. Therefore, when it is specifically necessary to adjust the distance between the A1 position and the B1 position, the B1 position can be mainly adjusted. At this time, the second driving mechanism 320 can flexibly adjust the B1 position by controlling its own power output stroke, time, etc.
[0053] In the above, when the coffee liquid brewing operation is completed, coffee grounds may remain in the channel 110, and the coffee grounds in the channel 110 need to be discharged. At this time, in one embodiment, when the first piston member 210 moves away from the first port 111, the second piston member 310 moves from the second port 112 to the first port 111 to scrape the grounds in the channel 110 outward. The outer peripheral side wall of the second piston member 310 is fully in contact with the inner wall of the channel 110, so that the coffee grounds remaining on the inner wall of the channel 110 can be fully scraped out during the movement from the second port 112 toward the first port 111, specifically, during the movement from the B0 position toward the first port 111, to achieve the purpose of preliminary cleaning of the inner wall of the channel 110. Then, according to actual needs, a scraping plate can be set outside the channel 110, and the scraping plate can be operated to move relative to the second piston member 310 exposed at the first port 111, so that the coffee grounds on the second piston member 310 are scraped off. Alternatively, a cleaning liquid may be introduced into the channel 110 to clean and remove a small amount of coffee grounds remaining in the channel 110 and on the second piston member 310 .
[0054] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
