[0037] Please refer to Figures 1 to 8 shown, the present utility model provides a beverage machine for a user to prepare a target beverage.

[0038] Below, take the coffee machine 10 for preparing coffee as an example for specific elaboration. However, it should be noted that the technical spirit involved in the following implementation manners can be equivalently applied to beverage machines for preparing other beverages except coffee.

[0039] Combined with Figures 1 to 8 shown, the coffee machine 10 includes a main body 1, a liquid supply component, and a control unit for controlling the operation of the coffee machine 10. The liquid supply component is communicatively connected to the control unit, and the start and stop of the liquid supply component are controlled by the control unit to provide water for extracting coffee powder into coffee.

[0040] Specifically, the liquid supply assembly includes a liquid outlet for cooperating with the powder container, a heating assembly 8 for heating the liquid, and a conveying assembly 9 for conveying the liquid to the liquid outlet. The heating assembly 8 and the conveying assembly 9 are both communicatively connected to the control unit. When the user needs to use water to brew the powder in the powder container, the heating assembly 8 is controlled to provide hot water at a preset temperature, and the conveying assembly 9 is controlled to convey the hot water at the preset temperature to the liquid outlet and discharge it into the powder container, so as to make the powder in the powder container into the corresponding target beverage.

[0041] In a specific embodiment, the liquid outlet is used to install the powder container, and the powder container is an extraction handle.

[0042] The main body 1 of the coffee machine has a receiving cavity 11. The heating assembly 8 and the conveying assembly 9 are located in the receiving cavity 11 to improve the safety performance of the coffee machine 10; the liquid outlet is provided in the external space of the main body 1, that is, the liquid outlet is located outside the receiving cavity 11, so as to facilitate the user to access the liquid provided by the liquid supply assembly.

[0043] The coffee machine 10 further includes a water storage tray assembly 2 disposed on the same side as the liquid outlet. The water storage tray assembly 2 is located in the external space of the receiving cavity 11. The water storage tray assembly 2 includes a water storage tray 21 connected to the main body 1 and having a water storage space, and a tray cover 22 disposed on the water storage tray 21. During the process of the user obtaining coffee liquid, generally, the container for receiving the coffee liquid is placed on the tray cover 22, and the cup mouth of the container is aligned with the liquid outlet of the coffee machine 10. The tray cover 22 is located at the exposed opening of the water storage tray 21 and corresponds to the position of the liquid outlet. The water storage tray 21 is used to hold waste liquid.

[0044] In a specific embodiment, the liquid outlet is located on the front wall of the main body 1. Correspondingly, the water storage tray assembly 2 is connected to the bottom of the front wall of the main body 1 to facilitate user operation.

[0045] In an alternative embodiment, the coffee machine 10 further includes a support portion provided at the bottom of the front wall of the main body 1. The support portion is located outside the receiving cavity 11. The support portion is provided with an installation cavity, and the water storage tray assembly 2 is detachably installed in the installation cavity to facilitate cleaning of the waste liquid in the water storage tray 21.

[0046] That is, the receiving cavity 11 is the interior or internal space of the main body 1, which is an invisible part during normal use by the user, while the space where the water storage tray assembly 2 is located is the exterior or external space of the main body 1, which is a visible part during normal use by the user.

[0047] The coffee machine 10 further includes a weighing module 3 provided inside the receiving cavity 11. The weighing module 3 includes a weighing sensor 31. The weighing sensor 31 is communicatively connected to the control unit. The tray cover 22 is suspended relative to the water storage tray 21, and the weighing sensor 31 is linked with the tray cover 22 to detect the weight of the target beverage.

[0048] The weighing module 3 is used to detect the weight of the target beverage in the container placed on the lid 22 of the tray, and feedback it to the control unit. When the weight of the target beverage reaches the preset amount, the control unit controls the liquid supply assembly to stop supplying liquid, making the control of the liquid volume more accurate. This can not only ensure a better extraction taste of coffee, but also ensure that the extraction taste of each cup of coffee is as consistent as possible.

[0049] The lid 22 of the tray being in a suspended state relative to the water storage tray 21 means that the lid 22 has a space for floating up and down relative to the water storage tray 21. Thus, after a container is placed on the lid 22, the lid 22 is linked with the weighing sensor 31: that is, under the gravity of the container and / or the target beverage in the container, the lid 22 will move downward, and transfer this movement amount to the linked weighing sensor 31, thereby obtaining the weight of the target beverage in the container.

[0050] For the coffee machine 10 in this embodiment, on the one hand, the lid 22 of the water storage tray assembly 2 is used as the weighing carrier. During the normal coffee brewing process by the user, the weight of the coffee liquid can be detected without setting an additional weighing structure, which is relatively simple and simplifies the structure and use of the coffee machine 10. At the same time, through the weighing sensor 31, the control of the water volume is more accurate, which can not only ensure a better extraction taste of coffee, but also ensure that the extraction taste of each cup of coffee is as consistent as possible. On the other hand, the weighing module 3 in this embodiment of the coffee machine 10 is arranged in the accommodation cavity 11, without occupying the space defined by the water storage tray assembly 2, and can prevent the water in the water storage tray 21 from contacting the weighing sensor 31. Thus, the safety performance and weighing accuracy of the coffee machine 10 are improved.

[0051] Specifically, the weighing module 3 further includes a circuit board 32 electrically connected to the weighing sensor 31, and the circuit board 32 is communicatively connected to the control unit. Arranging the weighing module 3 in the accommodation cavity 11 can also prevent the water in the water storage tray 21 from contacting the circuit board 32. Thus, the safety performance and weighing accuracy of the coffee machine 10 are improved.

[0052] Specifically, the main body 1 includes a casing that encloses to form the accommodation cavity 11, and the casing has a through groove 12 that communicates the inside and outside of the accommodation cavity 11. The lid 22 of the tray and the weighing module 3 are linked via the through groove 12.

[0053] In a specific embodiment, the through groove 12 is arranged on the bottom wall of the casing.

[0054] The coffee machine 10 further includes a bracket 6 that passes through the through groove 12. The bracket 6 has opposite first end and second end. The first end is connected to the lid 22 of the tray, and the second end is connected to the weighing module 3. Indirectly connecting the lid 22 and the weighing module 3 through the bracket 6 facilitates the assembly connection between the lid 22 and the weighing module 3.

[0055] In an alternative embodiment, the height of the second end of the bracket 6 is higher than the height of the first end, which can reasonably arrange the position of the weighing module 3 in the receiving cavity 11, reduce the occupation of the front and rear spaces of the receiving cavity 11, and improve the overall compactness of the coffee machine 10.

[0056] Specifically, the bracket 6 includes a connecting wall 61 extending in the height direction of the main body 1, a first wall 62 connected to the upper end of the connecting wall 61, and a second wall 63 connected to the lower end of the connecting wall 61. The first wall 62 and the second wall 63 extend in opposite directions, and the bracket 6 has a Z-shaped structure. The first wall 62 is used to connect to the weighing module 3. The second wall 63 is used to connect to the disk cover 22.

[0057] Wherein, the first end corresponds to the second wall 63, and the second end corresponds to the first wall 61; the height of the second end of the bracket 6 is higher than the height of the first end, specifically referring to the height of the first wall 61 being higher than the height of the second wall 63.

[0058] In an alternative embodiment, the bracket 6 is detachably connected to the disk cover 22, that is, the second wall 63 is detachably connected to the disk cover 22, which also facilitates the detachable connection between the water reservoir assembly 2 and the main body 1 and facilitates the cleaning of the water reservoir assembly 2.

[0059] Specifically, one of the second wall 63 and the disk cover 22 is provided with a socket 631, and the other is provided with a tab 221. The tab 221 passes through the socket 631 from top to bottom and supports on the second wall 63 / disk cover 22 provided with the socket 631 from the lower side of the socket 631 to achieve the assembly connection between the disk cover 22 and the bracket 6; the disassembly between the disk cover 22 and the bracket 6 is achieved by separating the tab 221 from the socket 631.

[0060] In an alternative embodiment, the weighing module 3 further includes a mounting box 33. The mounting box 33 includes a box body 331 having a mounting space and a cover body 332. The box body 331 has a mounting opening communicating with the mounting space, and the cover body 332 is used to open or close the mounting opening. The weighing sensor 31 and the circuit board 32 are both located in the mounting space. Thus, the risk of the steam generated by the steam rod 7 or the liquid in the water reservoir 21 or the like contacting the circuit board 32 / weighing sensor 31 can be reduced, the safety performance of the coffee machine 10 can be improved, and at the same time, the weighing accuracy of the weighing module 3 can be improved.

[0061] Wherein, a through hole 3321 is provided through the box body 331 or the cover body 332. The disk cover 22 is connected to the weighing sensor 31 through the through hole 3321, that is, the bracket 6 is connected to the weighing sensor 31 through the through hole 3321. That is, a through hole 3321 is provided on one side of the mounting box 33 to facilitate the connection between the bracket 6 and the weighing sensor 31.

[0062] Specifically, the mounting box 33 and the main body 1 can be fixedly connected by screws or the like to fix the weighing module 3 inside the main body 1.

[0063] In an alternative embodiment, the mounting box 33 includes an upper wall on the upper side, and a through opening 3321 is provided in the upper wall. That is, the tray cover 22 is connected to the weighing module 3 from the upper side of the mounting box 33, so that steam, liquid, etc. are not easily introduced into the mounting box 33, reducing the risk of steam, liquid, etc. entering the mounting box 33.

[0064] In a specific embodiment, the mounting opening is located on the upper side of the box body 331, and the cover body 332 shields the mounting opening above the box body 331. At this time, the cover body 332 is the upper wall of the above-mentioned mounting box 33. Of course, this is not limited thereto. In other embodiments, the mounting opening can also be located on the front, rear, left, right sides or even the lower side of the box body 331.

[0065] In an alternative embodiment, the weighing module 3 further includes a connecting plate 34 provided in the installation space, and the connecting plate 34 is connected to the weighing sensor 31. The connecting plate 34 includes a plate body 341 connected to the weighing sensor 31 and a connecting block 342 connected to the plate body 341 and passing through the through opening 3321. The bracket 6 is connected to the connecting block 342, and the weight borne by the tray cover 22 is transmitted to the weighing sensor 31 through the connecting plate 34. By adding the connecting block 342 in the connecting plate 34, an indirect connection between the tray cover 22 and the weighing sensor 31 can be achieved. The weighing sensor 31 does not need to be exposed outside the mounting box 33, which is convenient for the connection between the tray cover 22 and the weighing sensor. At the same time, the through opening 3321 can be shielded by the connecting block 342 to further prevent moisture such as steam from entering the mounting box 33, ensuring that the weighing module 3 can work stably.

[0066] Specifically, the first wall 62 of the bracket 6 and the connecting block 342 are firmly connected by fasteners such as screws.

[0067] Specifically, the weighing sensor 31 includes an opposite detection end and a fixed end. The fixed end is used to fix the weighing sensor 31 inside the mounting box 33, and the detection end is used for linkage connection with the tray cover 22, that is, the detection end is connected to the connecting plate 34.

[0068] In this embodiment, the detection end is set to obtain the deformation amount of the weighing sensor 31, and after transmitting the deformation amount to the control unit, the weight of the target drink is calculated. At this time, when the tray cover 22 moves downward under the gravity of the container and / or the target drink in the container, it will drive the associated weighing sensor 31 to deform, so as to obtain the weight of the target drink in the container. In other embodiments, the detection end can also be set to directly obtain the weight of the target drink.

[0069] Specifically, the detection end and the connection plate 34 can be fixedly connected by screws or the like.

[0070] There is a first cushion block 343 between the plate body 341 and the detection end, which can make other parts of the plate body 341 except the part corresponding to the detection end in a suspended state, that is, the connection plate 34 only applies an external force to the detection end, avoiding interference between the connection plate 34 and other parts of the weighing sensor 31 except the detection end, and affecting the measurement accuracy of the weighing sensor 31.

[0071] In a specific embodiment, the plate body 341, the connection block 342 and the first cushion block 343 are of an integral structure. Simplify the structure of the connection plate 34 and simplify the assembly of the weighing module 3.

[0072] Preferably, the connection plate 34 is a metal plate. Correspondingly, the first cushion block 343 is a metal cushion block, which can avoid interference between the plate body 341 and other parts of the weighing sensor 31 except the detection end caused by the deformation of the first cushion block 343, and affect the measurement accuracy of the weighing sensor 31.

[0073] In an alternative embodiment, the mounting box 33 includes a bottom wall, the fixed end is fixed to the bottom wall, and there is a second cushion block 35 between the fixed end and the bottom wall. Make other parts of the weighing sensor 31 except the fixed end in a suspended state, avoiding interference between the bottom wall and the detection end, and affecting the measurement accuracy of the weighing sensor 31.

[0074] In a specific embodiment, the second cushion block 35 is a metal cushion block, which can ensure that the contact surface between the weighing sensor 31 and the second cushion block 35 is relatively flat, avoiding affecting the measurement accuracy of the weighing sensor 31 due to the deformation of the second cushion block 35.

[0075] Specifically, the fixed end can be fixedly connected to the metal cushion block by fasteners such as screws to achieve the fixed connection between the fixed end and the bottom wall.

[0076] In a specific embodiment, the fixed end and the detection end are arranged in the front-back direction, that is, the weighing sensor 31 is placed in the front-back direction. The detection end is located at the front end. In an alternative embodiment, the height of the position where the weighing module 3 is located is higher than the height of the position where the through groove 12 is located. It can increase the distance between the through groove 12 and the weighing module 3, thereby increasing the path of steam and other moisture entering the receiving cavity 11 from the through groove 12, minimizing the contact between steam and other moisture and the weighing module 3, and improving the operation stability of the weighing module 3.

[0077] In an alternative embodiment, the weighing module 3 further includes a limiting member 36 provided on the deformation path of the detection end to prevent the weighing sensor 31 from being over-deformed and causing the weighing sensor 31 to fail, and improving the reliability of the weighing module 3.

[0079] Specifically, the mounting box 33 further includes a front wall connected to the front end of the bottom wall. One end of the two adjacent ends of the limiting piece is connected to the bottom wall, and the other end is connected to the front wall, so as to improve the strength of the limiting piece and the limiting effect of the limiting piece on the weighing module 3.
