Description

Weighing base, weighing module and beverage preparation device TECHNICAL FIELD

[0001] The present application relates to the technical field of beverage preparation devices, in particular to a weighing base, a weighing module and a beverage preparation device. BACKGROUND

[0002] The existing beverage preparation device, such as a coffee machine, generally integrates coffee bean grinding, coffee powder transfer and brewing extraction functions. In order to ensure the quality of coffee, the amount of coffee powder for each cup of coffee should be strictly controlled, and a weighing module is usually integrated in the coffee machine to weigh the coffee powder before brewing extraction, so as to ensure the accuracy of the amount of coffee powder added for different types of coffee.

[0003] The existing beverage preparation device, such as a coffee machine, generally integrates coffee bean grinding, coffee powder transfer and brewing extraction functions. In order to ensure the quality of coffee, the amount of coffee powder for each cup of coffee should be strictly controlled, and a weighing module is usually integrated in the coffee machine to weigh the coffee powder before brewing extraction, so as to ensure the accuracy of the amount of coffee powder added for different types of coffee.

[0004] The weighing assembly includes a weighing cavity for receiving coffee powder ground by a grinding structure. After the coffee powder is weighed, the cover structure is driven by the cover driving part to open the weighing cavity, and the coffee powder in the weighing cavity can be transferred to the brewer for brewing extraction. The weighing assembly is provided with an uncapping driving structure, and the weighing assembly is also electrically connected with other modules. Therefore, the line from the weighing assembly is complex, which makes the internal structure of the coffee machine more cluttered after the weighing assembly is installed in the coffee machine, and the risk of incorrect or damaged connection of the line is high.

[0005] Extracting a cup of high-quality coffee requires considering many elements, and one of the most important factors is coffee powder.

[0095] The present application shown in Figs. 1 to 4 provides a beverage processing device, which can be but is not limited to a coffee machine, a soybean milk machine or a juicer and the like. In the following description, for the convenience of description, a coffee machine will be taken as an example for specific description, and other devices can be adapted accordingly.

[0096] The beverage processing device comprises a weighing module, and the weight of coffee powder can be measured by the weighing module, so that the amount of coffee powder in each type of coffee can be quantified during the preparation of coffee, thereby improving the quality of coffee.

[0097] Specifically, referring to FIGS. 1, 2 and 4, the weighing module 100 comprises a weighing base 1 and a weighing module 2. The weighing module 2 can be supported and fixed on the weighing base 1 at a certain height, so as to facilitate the taking and placing of the weighing container 21 in the weighing module 2.

[0098] At least part of the weighing module 2 is arranged to protrude from the first side of the base body toward the weighing base 1. At least part of the two clamping portions 113 of the weighing base 1 is arranged to protrude from the second side of the base body. The first side and the second side are opposite sides of the base body.

[0099] In this embodiment, when the weighing module 2 is arranged on the base body, one side of the weighing module 2 protrudes from the first side of the base body. Specifically, the weighing container 21 of the weighing module 2 can be arranged to protrude from one side of the base body, so as to facilitate the receiving and transferring of powder (such as coffee powder). The center of gravity of the entire weighing module 100 is biased toward the first side. By arranging the two clamping portions 113 to protrude from the second side of the base body, and the first side and the second side are opposite, the overall center of gravity of the weighing module 100 is more centered, and the entire weighing module 100 is more stable and less likely to tilt toward one side. The stability of the weighing module 100 is ensured, thereby ensuring the accuracy of the weighing of the weighing module 100.

[0100] For the weighing base 1, the weighing base 1 comprises a base body, two clamping portions 113 and a first connecting portion 115.

The first connecting portion 115 is arranged on the base body and is adapted to form a fixed connection with the external structure in the first direction.

[0101] By setting the positioning groove 116 at the bottom of the chassis body, the fixed position of the weighing chassis 1 can be quickly found through the positioning groove 116, so that the weighing chassis 1 can be quickly and preliminarily positioned, and the foolproofness is effectively prevented. The two clamping portions 113 can clamp the chassis body to the external structure to form positioning in the horizontal direction, and then the first connecting portion 115 is connected and fixed to the external structure, and the clamping direction of the clamping portion 113 is consistent with the connecting direction of the first connecting portion 115, avoiding the weighing chassis 1 from being pulled out of the clamping portion 113, so that the weighing chassis 1 can be completely fixed. Moreover, by clamping the two clamping portions 113, compared with the connection mode of all screws, the alignment of each hole does not need to be accurately set, the installation operation of the weighing chassis 1 is more convenient, and the manufacturing precision of the weighing chassis 1 is smaller, so that the manufacturing cost is lower. Moreover, by the first connecting portion 115 and the two clamping portions 113, three fixed points connected to the external structure are formed, so that the fixing of the weighing chassis 1 is more reliable and not easy to shake, and the stability of the weighing module 100 is better, so as to ensure the weighing accuracy of the weighing module 100.

[0102] Preferably, the two clamping portions 113 are symmetrically arranged on both sides of the positioning groove 116, and the first connecting portion 115 and the two clamping portions 113 are arranged in a non-linear manner, that is, a triangular fixing is formed between the two clamping portions 113 and the first connecting portion 115, so that the fixing of the chassis body is more reliable, and the fixing of the entire weighing module 100 is more reliable and not easy to shake.

[0103] Preferably, as shown in FIGS. 3 and 4, the first connecting portion 115 is provided as a first connecting hole 1151, the first connecting hole 1151 is arranged in extension along the first direction, each clamping portion 113 can be provided as a clamping groove 1131, each clamping groove 1131 is arranged in extension along the first direction, and the side of each clamping groove 1131 away from the first connecting portion 115 is arranged in an open manner.

[0104] Specifically, the weighing module 100 can further include a plurality of connecting members, which can be provided as screws or bolts, etc. One of the connecting members is arranged in the first connecting hole 1151 and the corresponding mounting hole of the external structure (such as a coffee machine shell or a brewing module of a coffee machine, etc.) to fix the first connecting portion 115 to the external structure.

[0105] Moreover, the external structure can be provided with studs, the two clamping grooves 1131 are clamped on the corresponding two studs, and then another two connecting members are inserted into the mounting holes of the corresponding two clamping grooves 1131 and the corresponding studs of the external structure, so that the clamping part 113 is fixed on the external structure, thereby further improving the connection strength and making the connection more stable.

[0106] Of course, the first connecting part 115 and the clamping part 113 are not limited to the above-mentioned one. In other embodiments, the first connecting part 115 and the clamping part 113 can be provided in the form of a clamping hook structure, or a magnetic attraction structure, or a combination of a clamping hook and a screw, etc.

[0108] Moreover, as shown in FIGS. 1 and 3, the clamping groove 1131 is a "U"-shaped long hole, and one end of the long hole is arranged in an open manner. During installation, the stud can be inserted into the long hole from the open end of the long hole, so that the screw is inserted into the stud and is pressed against the inner side of the hole side wall of the long hole, thereby connecting and fixing the clamping groove 1131 and the stud of the external structure. Moreover, through the long hole, when the size of the external structure changes slightly, the stud on the external structure can be connected to different positions of the long hole, so that the installation operation is more convenient, the adaptability of installation is better, and the requirement for the installation precision of the connection part is not too high, thereby reducing the manufacturing cost.

The weighing base 11 is arranged in a substantially square block shape, the first connecting part 115 and the two clamping parts 113 are arranged on the weighing base 11 in a non-linear manner, so as to form a triangular connection relationship, thereby making the fixation of the weighing base 11 more stable.

[0122] Specifically, for the weighing base 1', as shown in FIGS. 2 and 4, the weighing base 1' includes a support bottom plate 11', a support side plate 12', and a support top plate 13'. It should be noted that when the weighing assembly 100' is normally working, the support bottom plate 11' is arranged at the bottom of the support side plate 12', and the support top plate 13' is located at the top of the support side plate 12'; the support side plate 12' is arranged around the periphery of the support bottom plate 11'; and the support top plate 13' and the support bottom plate 11' are located at opposite ends of the support side plate 12' in the up-down direction, respectively.

[0123] Further, as shown in FIG. 8, the support top plate 13' includes a top plate main body 131' and a plurality of top side plates 132' protruding from the periphery of the top plate main body 131', and the plurality of top side plates 132' protrude from the upper surface of the top plate main body 131'. Specifically, the top side plate 132' is provided with three, the above-mentioned first direction can refer to the left-right direction of the weighing base 1', and the three top side plates 132' are respectively located at the left and right sides of the weighing base 1' and the rear side of the weighing base 1', and the open side of the above-mentioned accommodating cavity is also located at the rear side. The top plate main body 131' is connected to the support side plate 12', the plurality of top side plates 132' are used for mounting the circuit board of the cover driving component 3' thereon, and the wire clamping structure 14' is arranged on the top side plate 132' at the open side of the accommodating cavity, that is, the wire clamping structure 14' is located on the top side plate 132' at the rear side, so as to clamp and bind the guide wire drawn out from the open side of the accommodating cavity.

[0124] Preferably, as shown in FIG. 8, two wire clamping grooves 141' are protruded on the top side plate 132' at the rear side, and each wire clamping groove 141' is provided with a clamping notch at the side away from the top side plate 132', and the lead wire can be clamped in the wire clamping groove 141' from the clamping notch, and the binding operation is simpler and more convenient.

[0125] Further, a plurality of reinforcing ribs 142' are provided on the top side plate 132' at the rear side, and the plurality of reinforcing ribs 142' are connected to the outer circumferential side of each wire clamping groove 141' to strengthen the strength of each wire clamping groove 141' to avoid breakage of the wire clamping groove 141', so that more lead wires can be clamped.

[0126] As shown in FIGS. 7 and 8, the cover driving component 3' includes a cover driving motor 31' and a transmission component 32' connected to the cover driving motor 31'. The cover driving motor 31' is arranged below the support top plate 13' and connected to the transmission component 32'. The transmission component 32' is arranged above the support top plate 13' and connected to the cover structure 22'. The cover driving motor 31' drives the transmission component 32' to rotate. Under the cooperation of the transmission component 32' and the cover structure 22', the cover structure 22' is driven to move towards or away from the weighing cavity 21', so that the cover structure 22' can open or close the weighing cavity 21'.

[0127] Specifically, the weighing cavity 21' is arranged in a funnel shape with both ends open. The upper end opening of the weighing cavity 21' is a material receiving port, and the lower end opening is a material dropping port. The cover opening structure can open and close the material dropping port. When weighing, the cover opening structure is arranged to close the material dropping port. The coffee powder can enter the weighing cavity 21' from the material receiving port. The material in the weighing cavity 21' can be weighed by the weighing sensor. After weighing is completed, the cover structure 22' can be driven by the cover driving motor 31' to open the material dropping port, so that the coffee powder can fall into the next process, such as the brewing cylinder of the brewing device, to conveniently and accurately brew the coffee powder.

[0128] Further, as shown in FIG. 5 and FIG. 8, the weighing cavity 21' is protrudingly arranged in front of the weighing base 1', and is connected to the support top plate 13' through a connecting arm, so that the weighing cavity 21' is arranged in a suspended state in front of the weighing base 1', so that the weighing cavity 21' is better for receiving and discharging materials, and the cover structure 22' is slidingly arranged on the connecting arm. The transmission component 32' includes a transmission rod 321' and a transmission block 322' connected to the cover structure 22', and a long hole extending in the left-right direction is arranged on the transmission block 322', one end of the transmission rod 321' is connected to the cover driving motor 31', and the other end of the transmission rod 321' is movably sleeved in the long hole. The cover driving motor 31' drives the transmission rod 321' to rotate, so that the transmission rod 321' abuts against the hole wall of the long hole, so that the transmission block 322' is displaced in the front-rear direction, thereby driving the cover structure 22' to move in the front-rear direction to open or close the material discharge port, thereby realizing automatic feeding and automatic discharging of coffee powder.

[0129] It can be understood that a controller can be arranged on the beverage processing device, and the controller can be electrically connected with the cover driving motor 31', so as to control the cover driving motor 31' to work. Therefore, an electric connection lead wire is arranged between the controller and the cover driving motor 31', and between the cover driving motor 31' and the power supply structure, and the plurality of lead wires are fixed and bound through the wire clamping groove 141', so that the connection state of each lead wire is more easily observed, and the whole weighing assembly 100' is more regular and compact.

[0130] Moreover, since the weighing cavity 21' is protrudingly arranged in front of the weighing base 1', the overall center of gravity of the whole weighing assembly 100' is offset forward. Therefore, the fixed clamping groove 111' is further arranged on the support bottom plate 11', preferably, two fixed clamping grooves 111' are arranged, the two fixed clamping grooves 111' are arranged on the same side of the weighing base 1' and are spaced apart in the up-down direction of the weighing base 1', and the two fixed clamping grooves 111' are protrudingly arranged on the rear side of the weighing base 1' to be connected and fixed with other structures in the beverage processing device, so that the center of gravity of the whole weighing base 1' can be more centered, thereby being more stable after being installed and fixed. The axis direction of the clamping region of the fixed clamping groove 111' is perpendicular to the axis direction of the clamping region of the wire clamping structure, that is, the fixed clamping groove 111' can be clamped and fixed on a structure extending in the up-down direction, so that the support bottom plate 11' can better fit on the clamped structure, and the fixing of the weighing assembly 100' is more reliable.

[0131] Please refer to FIG. 9 to FIG. 14, the present application provides another shell assembly 100'', which can be applied in a weighing module, and the weighing module can be applied in a beverage processing device.

[0132] It should be noted that, for the sake of convenience, in the following embodiments, the shell assembly 100'' is taken as an example for illustration, which has vertical, horizontal and longitudinal directions arranged in pairs in a cross manner. In actual application, the vertical direction can correspond to the direction of gravity, and then the vertical direction has upward and downward directions facing each other; the horizontal and longitudinal directions correspond to two directions approximately perpendicular in the horizontal plane.

[0133] Specifically, the shell assembly 100'' includes a base 110'', a support seat 120'' and a top seat 130''. The support seat 120'' includes a first vertical plate 121'' and two second vertical plates 122'' separately arranged on the two lateral sides of the first vertical plate 121''. The two second vertical plates 122'' are bent and extended from the first vertical plate 121'' along the longitudinal direction to jointly enclose a receiving cavity with the first vertical plate 121'' and the two second vertical plates 122'', which is open at the top and the bottom. The top seat 130'' is connected and fixed with the support seat 120'' and covers the top opening of the receiving cavity. The base 110'' is connected and fixed with the support seat 120'' and covers the bottom opening of the receiving cavity. The first vertical plate 121'' and the two second vertical plates 122'' are processed and formed by twice bending of a plate material.

[0134] In the technical solution provided by the present application, the base 110'' forms a bottom support for mounting the support seat 120'' and the base 110''. The top seat 130'' forms a top support for mounting part of the components of the weighing module. The receiving cavity formed by the support seat 120'' is used for mounting the remaining components of the weighing module. The support seat 120'' is directly formed by twice bending of a same plate material to form the first vertical plate 121'' and the two second vertical plates 122''. On the one hand, this helps to simplify the disassembly and assembly of the first vertical plate 121'' and the second vertical plate 122''. On the other hand, this helps to increase the connection strength of the first vertical plate 121'' and the second vertical plate 122''. In addition, this helps to make the shape of the first vertical plate 121'' and the second vertical plate 122'' more suitable for the shape of the base 110'' and the top seat 130'', thereby increasing the matching degree of the top seat 130'', the base 110'' and the support seat 120''. Through the improvement of the shell assembly 100'', the overall weighing module has reduced forming and disassembly difficulty, and the structural matching degree and compactness between the components are improved to some extent.

[0135] It can be understood that the first vertical plate 121'' extends and spreads along the vertical and horizontal directions, and the second vertical plate 122'' extends and spreads along the vertical and longitudinal directions, so that the receiving cavity penetrates along the longitudinal direction and forms a top opening and a bottom opening.

[0136] The top end opening is adapted to be detachably connected with the top seat 130''. For example, the top seat 130'' is integrally supported on the top end of the support seat 120'', and the bottom end of the top seat 130'' covers the top end opening of the accommodating cavity. Alternatively, as shown in FIGS. 3-4, at least the lower section of the top seat 130'' is inserted and fixed in the accommodating cavity. In one aspect, the top seat 130'' and the support seat 120'' are arranged in a mutual insertion manner, i.e., the outer wall of the top seat 130'' and the inner cavity wall of the accommodating cavity are in sliding connection, so that the top seat 130'' and the support seat 120'' are guided by each other during insertion, and the top seat 130'' and the support seat 120'' are more easily installed in place. In another aspect, since the first vertical plate 121'' and the two second vertical plates 122'' are formed by bending the same plate material, by inserting at least the lower section of the top seat 130'' in the accommodating cavity, the first vertical plate 121'' and the two second vertical plates 122'' can be transversely and longitudinally supported by at least the lower section of the top seat 130'', which helps to maintain the shape of the first vertical plate 121'' and the two second vertical plates 122''.

[0137] The bottom end opening is adapted to be detachably connected with the bottom seat 110''. For example, the first vertical plate 121'' and the two second vertical plates 122'' in the support seat 120'' are directly supported on the top end of the bottom seat 110'', and the top end of the bottom seat 110'' covers the bottom end opening of the accommodating cavity. Alternatively, as shown in FIGS. 3-4, at least the upper section of the bottom seat 110'' is inserted and fixed in the accommodating cavity. As described above, in one aspect, the bottom seat 110'' and the support seat 120'' are arranged in a mutual insertion manner, i.e., the outer wall of the bottom seat 110'' and the inner cavity wall of the accommodating cavity are in sliding connection, so that the bottom seat 110'' and the support seat 120'' are guided by each other during insertion, and the bottom seat 110'' and the support seat 120'' are more easily installed in place. In another aspect, since the first vertical plate 121'' and the two second vertical plates 122'' are formed by bending the same plate material, by inserting at least the upper section of the bottom seat 110'' in the accommodating cavity, the first vertical plate 121'' and the two second vertical plates 122'' can be transversely and longitudinally supported by at least the upper section of the bottom seat 110'', which helps to maintain the shape of the first vertical plate 121'' and the two second vertical plates 122''.

[0138] It should be noted that the structures, such as the size and shape, of the two second vertical plates 122'' can be the same, and they are arranged symmetrically about the vertical center line of the first vertical plate 121''. Alternatively, the structures of the two second vertical plates 122'' can be different, i.e., at least in size and shape, they are partially or completely different. However, for the purpose of understanding and for the purpose of making the support of the housing assembly 100'' more balanced and stable in actual application, in the following embodiments, the structures of the two second vertical plates 122'' are taken as an example for illustration.

[0139] In view of this, the bottom end of the top base 130'' and / or the top end of the bottom base 110'' is / are partially recessed with a limiting groove 150''; the second vertical plate 122'' is spaced apart with two second grooves 122a'' corresponding to the limiting groove 150'', and the second grooves 122a'' are substantially vertically long-shaped, so as to substantially divide the entire second vertical plate 122'' into a part between the two second grooves 122a'' and two parts outside the two second grooves 122a''. The part between the two second grooves 122a'' of the second vertical plate 122'' is inwardly folded to form a second flange 122b'', which is inserted into the limiting groove 150''. The folding size of the second flange 122b'' is matched with the corresponding limiting groove 150''. Through the insertion connection of the second flange 122b'' and the limiting groove 150'', the insertion between the top base 130'' and the support base 120'' and / or the insertion between the bottom base 110'' and the support base 120'' in the longitudinal and transverse directions is positioned and limited; and since the second flange 122b'' has a certain elastic deformation capacity, it is helpful to realize the elastic support between the top base 130'' and the support base 120'' and / or the elastic support between the bottom base 110'' and the support base 120''.

[0140] In actual application, taking the assembly between the top base 130'' and the support base 120'' as an example, at least one limiting groove 150'' can be formed on each transverse side of the top base 130''; and the second flange 122b'' is matched with the position and size of each limiting groove 150''.

[0141] In addition to the above, the part outside the two second grooves 122a'' of the second vertical plate 122'' forms a connecting part 122c'', and the inner cavity wall at the connecting part 122c'' is in surface contact with the outer side wall of the corresponding top base 130'' and / or the outer side wall of the corresponding bottom base 110'', so that the detachable connection and fixation between the support base 120'' and the top base 130'' and / or the support base 120'' and the bottom base 110'' can be realized in the area of the surface contact through a detachable connection structure. The detachable connection mode can be one or a combination of screwing, buckling, magnetic attraction, adhesion, and vacuum suction, but is not limited thereto.

[0142] It can be understood that the shell assembly 100'' can be integrated with other components in the weighing module when applied to the weighing module. When the weighing module is applied to the beverage preparation device, the weighing module needs to be fixed at a mounting area of the beverage preparation device continuously or periodically, and is fixedly connected or movably connected with the body to be loaded. Therefore, in an embodiment, a slot 111'' is recessed in one longitudinal side of the base 110'', and the slot 111'' is used for inserting and connecting the insertion protrusion of the body to be loaded. The other longitudinal side of the base 110'' is locally recessed to form an avoiding slot 112'' corresponding to the slot 111''. The avoiding slot 112'' and the slot 111'' are not directly connected, and the base 110'' forms a blocking structure between the avoiding slot 112'' and the slot 111''. A threaded hole 113'' is formed in the blocking structure along the longitudinal direction, and the threaded hole 113'' is connected with the slot 111'' and the avoiding slot 112''. The shell assembly 100'' further comprises a screwing piece 140'', which is threadedly connected with the threaded hole 113'' and extends into the slot 111'' to connect and fix the insertion protrusion, so as to fix the insertion protrusion at the base 110''. That is, the weighing module is fixedly connected to the body to be loaded.

[0143] Then, two first slots 121a'' are spaced apart and arranged at the avoiding slot 112'' of the first vertical plate 121''. The first slots 121a'' also extend along the vertical direction and have a long and narrow shape. The first vertical plate 121'' is folded inwardly to form a first folded edge 121b'' at the position between the two first slots 121a'', and the first folded edge 121b'' extends into the avoiding slot 112'' and abuts against the screwing piece 140''. In this way, when the screwing piece 140'' is connected to the threaded hole 113'', the first folded edge 121b'' abuts against one end of the screwing piece 140'' which is away from the threaded hole 113'', so as to prevent the screwing piece 140'' from being pulled out.

[0144] Further, the first folded edge 121b'' extends obliquely relative to the first vertical plate 121''. In this way, the first folded edge 121b'' has a certain elastic deformation capacity relative to the first vertical plate 121''. That is, the first folded edge 121b'' can be folded to form an avoiding structure during the process of inserting the screwing piece 140'' into the avoiding slot 112'' and threadedly connecting the screwing piece 140'' with the threaded hole 113''. Then, when the screwing piece 140'' is connected to the threaded hole 113'', the first folded edge 121b'' can be reset and elastically abut against the screwing piece 140''.

[0145] In addition, the base 110'' is provided with a reinforcing rib 114'' in the avoiding groove 112'', the reinforcing rib 114'' is arranged at least on one side of the threaded hole 113'' and connected with at least three side walls of the avoiding groove 112''. The reinforcing rib 114'' can be used as a reinforcing structure of the avoiding groove 112'' to support the structure of at least three side walls of the avoiding groove 112''; on the other hand, the reinforcing rib 114'' can be used to laterally stop and support the screwing piece 140''.

[0146] In view of the above, the present application also provides a weighing module, which comprises the shell assembly 100'', the mounting seat 200'', the receiving container 300'', the driving device 400'' and the weighing device 500''. The mounting seat 200'' is suspended above the top seat 130''. The receiving container 300'' comprises a container body 310'' fixedly installed on the mounting seat 200'' and an opening and closing piece 320'' movably installed on the mounting seat 200''. The container body 310'' is provided with a receiving channel 311''. The opening and closing piece 320'' can open and close the receiving channel 311'' during movement. The driving device 400'' comprises a driver 410'' received in the receiving cavity and a transmission assembly 420'' at least partially exposed outside the receiving cavity. The transmission assembly 420'' is connected with the driver 410'' and the opening and closing piece 320'' to drive the opening and closing piece 320'' to move under the driving of the driver 410''. The weighing device 500'' comprises a weighing part 510'' fixedly connected with the mounting seat 200''.

[0147] Of course, the present application also provides a beverage processing device, which comprises the grinding module and the weighing module. The weighing module is used to weigh the powder obtained by the grinding module.

[0148] The present application is not limited to a specific type of beverage processing device. The beverage processing device can be a bean grinder, which mainly comprises a grinding module to grind the bean into powder. In this case, the weighing module is arranged downstream of the grinding module. Alternatively, the beverage processing device can be a fully automatic coffee machine, which comprises a brewing module in addition to the grinding module. In this case, the weighing module is arranged between the downstream of the grinding module and the upstream of the brewing module. The beverage processing device further comprises a machine shell for receiving various functional modules.

[0149] The grinding module can be, but is not limited to, comprising a grinding cylinder and a grinding mechanism. The grinding cylinder is internally formed with a grinding cavity; the grinding mechanism comprises, for example, two knife plates that are relatively movably arranged and a first driving device 400'' that drives at least one of the knife plates to move. The grinding gap between the two knife plates is formed to perform a grinding and crushing operation such as piercing, grinding, stirring, and the like on the granular material such as coffee beans. The grinding gap is arranged to be adjustable or fixed. The downstream of the grinding module, i.e., the outlet end of the grinding cylinder, can discharge the powder obtained by grinding to the outside.

[0150] The grinding module can directly access coffee beans from the outside of the machine shell. Alternatively, in an application, the machine body further comprises a bean bin arranged in the machine shell. The bean bin is a container assembly capable of providing a space to accommodate coffee beans. In actual application, the bean bin can be arranged as one or several according to actual needs. When the bean bin is arranged as several, each bean bin can be used to store the same coffee beans or different types of coffee beans.

[0151] The brewing module can be, but is not limited to, comprising a brewing cylinder and a brewing mechanism. The upstream of the brewing module, i.e., the inlet end of the brewing cylinder.
