[0040] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0041] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.

[0042] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0044] The embodiment of the present invention provides an automatic coffee brewing machine 100, such as Figures 1 to 5 As shown, the automatic coffee brewing machine 100 includes a frame 1 and a bean grinding device 2, a brewing device 3, a carrier 4, a filter container 5 and a power source device 6 arranged on the frame 1.

[0045] The bean grinding device 2 and the brewing device 3 are arranged in sequence. The carrier 4 is movably arranged on the frame 1, and the filter container 5 is detachably arranged on the carrier 4; when the filter container 5 is assembled on the carrier 4, the filter container 5 can be stably loaded on the carrier 4, and the filter container 5 can be moved to the position of the bean grinding device 2 or the brewing device 3 for grinding or brewing operations. When the filter container 5 needs to be removed for cleaning, an external force acts on the filter container 5 to remove the filter container 5 from the carrier 4, and the filter container 5 can be removed from the automatic coffee brewing machine 100 for cleaning, which is simple and convenient to operate.

[0046] The output end of the power source device 6 is connected to the carrier 4. When the filter container 5 is placed on the carrier 4, the power source device 6 can drive the filter container 5 on the carrier 4 to move to the bean grinding device 2 or the brewing device 3. When the power source device 6 drives the filter container 5 to move to the bean grinding device 2, it specifically drives the filter container 5 to move to the powder outlet of the bean grinding device 2. At this time, the bean grinding device 2 is controlled to start grinding coffee powder. The bean grinding device 2 is a conventional structure that can automatically grind coffee beans into coffee powder and automatically discharge powder, and no excessive description is given here. After the filter container 5 receives a certain amount of coffee powder, the power source device 6 drives the filter container 5 to move to the brewing device 3. At this time, the brewing device 3 fixes the filter container 5 and performs powder pressing and brewing.

[0047] In summary, the automatic coffee brewing machine 100 detachably connects the filter container 5 with the carrier 4 so that the filter container 5 can be quickly assembled and disassembled for cleaning. When the filter container 5 needs to be assembled on the carrier 4, the power source device 6 can drive the filter container 5 to move to the positions of the bean grinding device 2 and the brewing device 3 in sequence through the carrier 4 to perform grinding and brewing operations in sequence. That is, the user only needs to load the filter container 5 on the carrier 4 to realize the automatic grinding and brewing process of coffee. It has the characteristics of simple structure and convenient operation, and the filter container 5 can be removed from the carrier 4 for cleaning after the coffee brewing process is completed, which can effectively avoid the problem that unclean cleaning causes coffee residues to remain on the filter container 5 to block the outflow of coffee liquid, and affects the flavor of the brewed coffee and the user experience.

[0048] In some embodiments, the carrier 4 is provided with a clamping hole 41, which is a hole structure that is recessed inward along one side edge of the carrier 4 to form a side opening 42; the filter container 5 is detachably accommodated in the clamping hole 41, and the filter container 5 can be moved out of the clamping hole 41 through the opening 42. When the filter container 5 needs to be assembled on the carrier 4, the filter container 5 is sent into the clamping hole 41 through the opening 42 and fixed. For example, the filter container 5 can be clamped at the clamping hole 41 by a clamp, or can be clamped in the clamping hole 41 by elastic action. Any structure that can fix the filter container 5 in the clamping hole 41 in a natural state and can be separated from the clamping hole 41 under the action of external force is applicable, and no special restrictions are made here. At this time, the filter container 5 can be stably loaded on the carrier 4, and the filter container 5 can be moved to the position of the grinding device 2 or the brewing device 3 for grinding or brewing operations. When the filter container 5 needs to be removed for cleaning, external force is applied to the filter container 5 to move the filter container 5 out of the clamping hole 41 through the opening 42. The filter container 5 can then be removed from the automatic coffee brewing machine 100 for cleaning, which is simple and convenient to operate.

[0049] In some embodiments, Figure 1 and Figure 3 As shown, the orientation direction of the opening 42 intersects with the moving direction of the carrier 4. Preferably, the orientation direction of the opening 42 of the clamping hole 41 is perpendicular to the moving direction of the carrier 4. It can be understood that by setting the orientation direction of the opening 42 of the clamping hole 41 to intersect with the moving direction of the carrier 4, the filter container 5 can be separated from the opening 42 only under the action of an external force in a specific direction, which can effectively avoid the problem that the filter container 5 is separated from the opening 42 under the action of inertia when the power source device 6 drives the carrier 4 to reciprocate between the grinding device 2 and the brewing device 3.

[0050] In some embodiments, Figure 3 As shown, the carrier 4 includes a first connecting plate 43, a second connecting plate 44 and a third connecting plate 45, the second connecting plate 44 and the third connecting plate 45 are vertically connected to the first connecting plate 43, and the first connecting plate 43, the second connecting plate 44 and the third connecting plate 45 cooperate to form a U-shaped clamping hole 41 with an opening 42. The opening 42 of the U-shaped clamping hole 41 faces the outside of the frame 1, that is, corresponds to the user's operating side, and the shape of the U-shaped clamping hole 41 is arranged to facilitate the installation or removal of the filter container 5 on the carrier 4, and the filter container 5 can be stably loaded on the carrier 4.

[0051] In some embodiments, Figure 2 and Figure 3As shown, the filter container 5 includes a filter cartridge 51 and a handle 53, and the handle 53 is arranged on the body of the filter cartridge 51; a clamping body 52 is arranged on the top of the filter cartridge 51, and the clamping body 52 is detachably mounted on the edge of the clamping hole 41, and the filter cartridge 51 can be moved out through the opening 42 by rotating and moving the handle 53. The structure of the filter container 5 is adapted to the structure of the U-shaped clamping hole 41. Specifically, in the filter container 5, the filter cartridge 51 is a cylindrical structure, and the radial length of the filter cartridge 51 is less than the width of the clamping hole 41, so that the body of the filter cartridge 51 can be accommodated in the clamping hole 41, and the clamping body 52 is an annular body with an outer square and an inner circle, and the radial length of the outer edge of the clamping body 52 is greater than the width of the clamping hole 41, so that the clamping body 52 can be clamped on the edge of the clamping hole 41, so that the filter container 5 is suspended on the carrier 4 as a whole, and the filter container 5 can be stably loaded on the carrier 4, and it is convenient to move it out of the carrier 4. By providing the handle 53, it is convenient to apply external force to the handle 53 to install or remove the filter container 5 from the clamping hole 41 of the carrier 4 by rotating and / or moving, and the operation is simple and convenient. In addition, the bottom of the filter cartridge 51 can also be provided with conventional components such as a water outlet valve and a filter element for conventionally controlling the outlet of the liquid, so that the coffee liquid is automatically poured into the cup after brewing is completed, and the residue is left in the filter cartridge 51, which will not be described in detail here.

[0052] In some embodiments, Figure 2 and Figure 3 As shown, the power source device 6 includes a rotating power source device 64 and a transmission assembly 61; the output end of the rotating power source device 64 is connected to the carrier 4 through the transmission assembly 61 to drive the carrier 4 to reciprocate along the extension direction from the grinding device 2 to the brewing device 3. Among them, by setting the matching structure of the rotating power source device 64 and the transmission assembly 61, the rotating driving force of the rotating power source device 64 is converted into a linear driving force through the transmission action of the transmission assembly 61 to drive the carrier 4 to reciprocate along the extension direction from the grinding device 2 to the brewing device 3. Compared with the driving mode of the linear motor, the driving source and the carrier 4 can be arranged non-coaxially, so as to make full use of the internal space of the automatic coffee brewing machine 100 and improve the compactness of the structure. Of course, in other embodiments, the power source device 6 can also be a device such as a linear motor that can directly drive the carrier 4 to reciprocate linearly, and no special restrictions are made here.

[0053] In some embodiments, Figure 3As shown, the transmission assembly 61 includes a gear 62 and a rack 63, the output end of the rotating power source device 64 is connected to the gear 62 and drives the gear 62 to rotate, the rack 63 is arranged on the carrier 4, and the gear 62 and the rack 63 are meshed. Through the meshing transmission of the gear 62 and the rack 63, the rotational driving force of the rotating power source device 64 can be well converted into the linear motion of the carrier 4, thereby improving the stability of the motion. Of course, in other embodiments, the transmission assembly 61 can also be other devices that can convert the rotational driving force into the linear driving force, such as a spiral transmission, a worm transmission, etc., which are not particularly limited here.

[0054] In some embodiments, Figure 3 As shown, the frame 1 is provided with a guide member 11 extending from the bean grinding device 2 to the brewing device 3, and the carrier 4 is provided with a sliding member 46 adapted to the guide member 11, and the carrier 4 is slidably arranged on the guide member 11 through the sliding member 46. The guide member 11 can be a guide groove arranged on the frame 1, and the sliding member 46 can be a sliding block arranged on the carrier 4 and adapted to the guide groove, and the carrier 4 is slidably arranged on the guide groove through the sliding block to form a linear motion. Alternatively, the guide member 11 can be a guide boss arranged on the frame 1, and the sliding member 46 can be a slide groove opened on the carrier 4, and the carrier 4 is slidably arranged on the guide boss through the slide groove to form a linear motion, and no special restrictions are made here. Through the matching structure of the guide member 11 and the sliding member 46, the carrier 4 can reciprocate along a specific trajectory, so that it can be accurately moved to the bean grinding device 2 or the brewing device 3.

[0055] In some embodiments, Figure 4 As shown, the brewing device 3 includes a brewing body 31, a piston 32 and a piston driving mechanism 33; the piston driving mechanism 33 is arranged on the brewing body 31, and the output end of the piston driving mechanism 33 is connected to the piston 32. When the filter container 5 reaches the position of the brewing device 3, the piston driving mechanism 33 drives the piston 32 to extend into or out of the filter container 5. Among them, when the power source device 6 drives the filter container 5 to move to the brewing device 3, the piston driving mechanism 33 drives the piston 32 to move along the axis of the filter container 5 to the inside of the filter container 5 to press the coffee powder and brew the coffee. After the brewing is completed, the piston driving mechanism 33 drives the piston 32 to move in the opposite direction to leave the filter container 5 to release the pressing state. At this time, the filter container 5 can be moved to the unloading position such as the bean grinding device 2 for cleaning operation to complete the working cycle. In addition, it should be noted that the other unmentioned structures of the brewing device 3 are conventional structures that can automatically cooperate to brew coffee powder into coffee, and no excessive description is given here.

[0056] In some embodiments, Figure 4As shown, the piston 32 is provided with a hollow water inlet channel 322 along its central axis, and a plurality of water outlet holes 321 are provided at one end of the piston 32 close to the filter container 5, which are connected to the water inlet channel 322 and the filter container 5. The top of the piston 32 can be connected to the water inlet channel 322 through a water inlet hose, so as to adapt to the up and down movement of the piston 32. When the piston 32 presses the coffee powder in the filter container 5, hot water flows from the water inlet channel 322 through the water outlet holes 321 into the filter container 5, and the coffee powder is automatically brewed, which has the characteristics of simple structure and no need for manual operation.

[0057] In some embodiments, Figure 4 As shown, the brewing device 3 is provided with a first positioning device that cooperates with the filter container 5. When the filter container 5 reaches the position of the brewing device 3, the filter container 5 is connected to the brewing device 3 through the first positioning device. Specifically, the first positioning device includes a first positioning member 34 and a second positioning member 54, wherein the brewing device 3 is provided with a first positioning member 34, and the filter container 5 is provided with a second positioning member 54 that is magnetically attracted to the first positioning member 34. When the filter container 5 reaches the position of the brewing device 3, the filter container 5 is magnetically attracted to the first positioning member 34 through the second positioning member 54 to be connected to the brewing device 3. The first positioning member 34 and the second positioning member 54 can both be magnets. Through the magnetic attraction between the two, when the filter container 5 reaches the predetermined position of the brewing device 3, it can be accurately limited and fixed under the brewing device 3, so that the piston 32 can be accurately pressed into the filter container 5. Of course, in other embodiments, the first positioning member 34 and the second positioning member 54 are not limited to the magnetically attracted components, and the plug-in state of the socket and the plug-in column can also be used to accurately limit and fix the filter container 5 under the brewing device 3, without any special limitation.

[0058] In some embodiments, the bean grinding device 2 is provided with a second positioning device that cooperates with the filter container 5. When the filter container 5 reaches the position of the bean grinding device 2, the filter container 5 is connected to the bean grinding device 2 through the second positioning device. Specifically, the second positioning device includes a third positioning member and a fourth positioning member. The bean grinding device 2 is provided with a third positioning member, and the filter container 5 is provided with a fourth positioning member that is magnetically attracted to the third positioning member. When the filter container 5 reaches the position of the bean grinding device 2, the filter container 5 is magnetically attracted to the third positioning member through the fourth positioning member to connect with the bean grinding device 2. The third positioning member and the fourth positioning member are magnetically attracted to each other, so that when the filter container reaches the predetermined position of the bean grinding device 2, it can be accurately limited and fixed under the bean grinding device 2, so that the filter container 5 can accurately receive the ground coffee powder. Specifically in this embodiment, the third positioning member 34 and the first positioning member on the filter container 5 are the same positioning member, so that the filter container 5 can be accurately limited when it moves to the bean grinding device 2 or the brewing device 3.

[0059] In some embodiments, Figure 3 As shown, the frame 1 is provided with a first limit switch 12 near the bean grinding device 2, and the filter container 5 can contact the first limit switch 12 when it moves to the bean grinding device 2; the frame 1 is provided with a second limit switch 13 near the brewing device 3, and the filter container 5 can contact the second limit switch 13 when it moves to the brewing device 3. Among them, through the setting of the first limit switch 12 and the second limit switch 13, the filter container 5 on the carrier 4 can be accurately controlled to move to the preset position of the bean grinding device 2 or the brewing device 3, that is, stop moving, so as to carry out the next step of grinding beans or pressing powder brewing operation.

[0060] The automatic coffee brewing machine 100 further includes a control circuit (not shown) for grinding and brewing coffee beans, and controlling the movement of the filter container 5 and the carrier 4. Since the control circuit is a conventional component and the control method is also a conventional method, it is not the focus of the present invention and will not be described in detail here. In addition, the automatic coffee brewing machine 100 may also include conventional components such as a power supply and a display screen, which are not particularly limited here.

[0061] In some embodiments, Figure 1 and Figure 5 As shown, the frame 1 includes a bottom plate 14, a top plate 15, a support plate 16 and two vertical plates 17; the top plate 15 is arranged on the bottom plate 14 through the two vertical plates 17, the support plate 16 is arranged between the bottom plate 14 and the top plate 15, the bean grinding device 2 and the brewing device 3 are dispersedly arranged on the top plate 15 along the left and right directions, and the top plate 15 is provided with a first through hole connected to the powder outlet of the bean grinding device 2, and a second through hole for the piston 32 of the brewing device 3 to move up and down. The bearing member 4 is movably arranged on the support plate 16, and the opening 42 of the bearing member 4 faces the front side facing the user, and a shielding plate 18 is arranged at the front side between the top plate 15 and the support plate 16, and the height of the shielding plate 18 is lower than the height between the top plate 15 and the support plate 16, which can shield the structure of the bearing member 4 and the power source device 6 to form a protective effect, and on the other hand, avoid affecting the removal or assembly operation of the filter container 5.

[0062] In some embodiments, Figures 6 to 14 As shown, the automatic coffee brewing machine 100 further includes a coffee weighing device 7 , which includes a movable part 71 and a weighing frame 72 .

[0063] The movable member 71 has a placement position 715, and the placement position 715 is used to detachably install the filter container 5. The movable member 71 is movably arranged between the carrier 4 and the weighing frame 72, and the movable member 71 can move to a first position or a second position; when the movable member 71 is in the first position, the movable member 71 is separated from the weighing frame 72, and the movable member 71 is supported on the carrier 4; when the movable member 71 is in the second position, the movable member 71 is separated from the carrier 4, and the movable member 71 is supported on the weighing frame 72 to perform a weighing operation.

[0064] Among them, the weighing frame 72 is fixed on the bean grinding device 2, and the placement position 715 of the movable part 71 is correspondingly arranged at the powder outlet of the bean grinding device 2. When weighing is not performed, the movable part 71 is in the first position, the movable part 71 is separated from the weighing frame 72, and the movable part 71 is supported on the supporting member 4. At this time, the filter container 5 can be loaded on the placement position 715 of the movable part 71. After the filter container 5 is loaded, an external force is applied to control the movable part 71 to move to the second position. At this time, the movable part 71 is separated from the supporting member 4, and the movable part 71 is supported on the weighing frame 72. At this time, the coffee powder ground by the bean grinding device 2 enters the filter container 5. At this time, the weighing frame 72 can weigh the weight of the filter container 5 placed on the placement position 715. After weighing to the preset weight, the bean grinding device 2 closes the powder outlet state. Then, the filter container 5 can be driven by the power source device 6 to move the supporting member 4, thereby driving the filter container 5 to move out from the placement position 715 of the movable member 71, so that the filter container 5 is separated from the weighing frame 72. At this time, the filter container 5 can be driven by the power source device 6 to move to the position of the brewing device 3 to perform the brewing operation.

[0065] Based on the above-mentioned coffee weighing device 7, a coffee weighing method is provided herein, characterized in that the coffee weighing method comprises the following steps:

[0066] The movable member 71 is switched to the first position, at which time the movable member 71 is separated from the weighing frame 72, and the movable member 71 is supported on the bearing member 4, and the weighing frame 72 is in a non-weighing state relative to the movable member 71;

[0067] The movable member 71 is switched to the second position, at which time the movable member 71 is separated from the supporting member 4 and supported on the weighing frame 72 . At this time, the weighing frame 72 can weigh the filter container 5 placed on the movable member 71 .

[0068] In summary, the coffee weighing device 7 is implemented by movably arranging the movable part 71 between the supporting part 4 and the weighing frame 72, and switching the movable part 71 between the first position and the second position, wherein when the movable part 71 is in the first position, the movable part 71 is separated from the weighing frame 72, and the movable part 71 is supported on the supporting part 4, and the weighing frame 72 will not weigh the filter container 5 on the movable part 71, and when the movable part 71 is switched to the second position, the movable part 71 is separated from the supporting part 4, and the movable part 71 is supported on the weighing frame 72, and the weighing frame 72 can complete the weighing of the filter container 5 placed on the movable part 71. Therefore, the position state of the movable part 71 can be quickly switched to be supported on the weighing frame 72 according to the control, so that the coffee powder can be accurately weighed, and when weighing is not needed, the position state of the movable part 71 can be switched to be separated from the weighing frame 72, so that the movement state of the filter container 5 will not affect the state of the weighing frame 72, thereby not affecting the weighing accuracy of the weighing frame 72 when the filter container 5 moves.

[0069] In some embodiments, Fig.10 , Fig.11 and Fig.14 As shown, the weighing frame 72 is located above the bearing member 4, the movable member 71 is rotatably arranged on the bearing member 4, and the movable member 71 can rotate to the first position or the second position relative to the bearing member 4, and the weighing frame 72 is provided with a guide portion 721, and the guide portion 721 has a first inclined surface 722.

There is a gap between the receiving annular groove 711 of the movable member 71 and the supporting ring body 724 in the axial direction. When the movable member 71 is in the first position, there is no contact between the guide portion 721 of the supporting ring body 724 and the guide groove 712 of the movable member 71, and the weighing frame 72 is not subjected to force. The movable member 71 is supported by the supporting member 4 located below. When the movable member 71 rotates to the second position, the second inclined surface of the guide groove 712 gradually contacts the first inclined surface 722 of the guide portion 721. At this time, the continued rotation of the movable member 71 drives the movable member 71 to move upward in the axial direction between the supporting member 4 and the weighing frame 72 to separate from the supporting member 4, and switches to the supporting ring body 724 to support the movable member 71, so that the coffee powder in the filter container 5 can be accurately weighed.

Among them, by providing the elastic limiting member 725, when the movable member 71 rotates to the first position or the second position, it can be limited to the first limiting groove 713 or the second limiting groove to form an indication of rotation in place, and limit the further rotation of the movable member 71, effectively avoiding excessive rotation affecting the weighing effect. Specifically, in this embodiment, the elastic limiting member 725 includes a connecting column 7251 and a limiting block 7252; the connecting column 7251 is arranged on the outer ring edge of the supporting ring body 724 and extends along the circumferential direction of the supporting ring body 724, and a gap is formed between the column body of the connecting column 7251 and the outer ring edge of the supporting ring body 724, the connecting column 7251 has elastic properties, and the end of the connecting column 7251 is connected to the limiting block 7252.

[0075] In some embodiments, the support suspension 7231 includes a horizontal frame and two vertical frames, the horizontal frame is supported by the two vertical frames, the weighing sensor 7232 is arranged on the horizontal frame, the bottom ends of the two vertical frames are connected to the support ring body 724, wherein the horizontal frame can be fixedly connected to the grinding device 2 or the frame 1. Specifically, the vertical frame is a Z-shaped frame, which is used to avoid the upper end surface of the movable member 71 and facilitate the support ring body 724 to extend into the receiving ring groove 711 of the movable member 71.

[0076] In some embodiments, Figure 3 , Fig.10 and Fig.11 As shown, the placement position 715 is a clamping groove that penetrates along the first direction of the movable member 71. The filter container 5 can slide into the clamping groove along one end of the first direction to be fixed, and can also slide out through one end of the first direction to escape from the clamping groove. The power source device 6 drives the carrier 4 to move along the second direction. When the movable member 71 is located at the second position, the extension direction of the first direction is consistent with the extension direction of the second direction. The power source device 6 can drive the filter container 5 to escape from the placement position 715 and move to the brewing device 3 by driving the carrier 4. Therefore, the whole process of grinding, weighing and brewing can be automatically completed when the filter container 5 is loaded on the clamping groove of the movable member 71 and moved to the second position, which has the characteristics of simple structure and convenient operation.

[0079] In the initial state, the movable member 71 is in the first position. At this time, there is no contact between the guide portion 721 of the support ring body 724 and the guide groove 712 of the movable member 71, and the weighing frame 72 is not subjected to force. At this time, the penetration direction of the clamping groove of the movable member 71 is the front-to-back direction. The filter container 5 can be inserted along the opening of the clamping groove and placed on the movable member 71. After the filter container 5 is placed, the movable member 71 is rotated. During the process of the movable member 71 rotating to the second position, the second inclined surface of the guide groove 712 gradually contacts the first inclined surface 722 of the guide portion 721. At this time, the continued rotation of the movable member 71 will drive the movable member 71 moves upward in the axial direction between the carrier 4 and the weighing frame 72 to detach from the carrier 4, and switches to the support ring 724 to support the movable member 71. At this time, the coffee powder ground by the bean grinding device 2 enters the filter container 5, and the weighing frame 72 can weigh the coffee powder in the filter container 5. After weighing to a preset weight, the bean grinding device 2 is closed to discharge the powder. At this time, the penetrating direction of the clamping groove of the movable member 71 is the left-right direction, which is consistent with the direction in which the power source device 6 drives the carrier 4 to move. The power source device 6 drives the carrier 4 to drive the filter container 5 to detach from the clamping groove and move to the brewing device 3. Therefore, the whole process of grinding, weighing and brewing can be automatically completed when the filter container 5 is loaded on the clamping groove of the movable member 71 and moved to the second position, which has the characteristics of simple structure and convenient operation.
