The disclosure generally relates to an automated beverage preparation apparatus and, more particularly, to a material dispensing device, a material output volume detecting device, and a related damper device for use in an automated beverage preparation apparatus.
For many consumers, freshly made beverages are more attractive than factory-produced canned or bottled beverages in many aspects, such as freshness, taste, and/or flexibility of customizing ingredient combination. Therefore, many restaurants and beverage vendors offer a variety of freshly made beverages to meet the needs of their customers. The traditional approach of manually preparing freshly made beverages has many disadvantages. For example, it is not easy to maintain the taste consistency of freshly made beverages, personnel training requires considerable time and cost, and the preparation of the freshly made beverages often consumes a lot of labor time, or the like. As a result of rising labor costs and other factors (e.g., increased operating costs due to the impact of the pandemic or inflation), many restaurants and beverage vendors have begun to use a variety of machinery and equipment to provide or assist in the preparation of freshly-made beverages in order to reduce the required labor time and costs.
It is well known that many raw materials for use in preparing freshly made beverages are liquid materials which have a viscosity higher than water, for example, honey, various syrups, soy milks, nut pulps, fruit juice concentrates, fruit juices containing fruit fibers, tea-based liquids containing small particles (e.g., bubbles or tapioca balls), milk-based liquids, cooking oils, or other thick liquid material and so on. However, traditional beverage preparation machines lack appropriate mechanisms to accurately measure the usage amount of the liquid material of the aforementioned type, and thus it usually results in undesirable situations, e.g., the liquid volume of the freshly made beverage does not meet expectation or the taste of the freshly made beverage has bias.
An example embodiment of a material dispensing device of an automated beverage preparation apparatus is disclosed, comprising: a pump, comprising a material inlet and a material outlet, wherein the pump is arranged to operably pressure liquid material received through the material inlet to push the liquid material to the material outlet; a damper device, arranged to operably buffer liquid material flowing through the damper device; a flowmeter, coupled with the damper device, arranged to operably measure a flow of the liquid material outputted from the damper device; and a material output tube; wherein the damper device comprises: a damper base, comprising a material entrance hole, a material exit hole, and a material buffer chamber located between the material entrance hole and the material exit hole, wherein the material entrance hole is arranged to operably transmit received liquid material to the material buffer chamber, the material buffer chamber is arranged to temporarily store the liquid material flowing into the material buffer chamber, and the material exit hole is arranged to operably transmit the liquid material passed through the material buffer chamber toward the flowmeter; a diaphragm, covered on the material buffer chamber; and a fastening element, positioned on the diaphragm and having a hollow portion; wherein when a volume of the liquid material within the material buffer chamber exceeds a predetermined amount, the diaphragm deforms to protrude outward, so that a part of the diaphragm enters the hollow portion of the fastening element.
An example embodiment of a material output volume detecting device of an automated beverage preparation apparatus is disclosed, comprising: a damper device, arranged to operably buffer liquid material flowing through the damper device; and a flowmeter, coupled with the damper device, arranged to operably measure a flow of the liquid material outputted from the damper device; and wherein the damper device comprises: a damper base, comprising a material entrance hole, a material exit hole, and a material buffer chamber located between the material entrance hole and the material exit hole, wherein the material entrance hole is arranged to operably transmit received liquid material to the material buffer chamber, the material buffer chamber is arranged to temporarily store the liquid material flowing into the material buffer chamber, and the material exit hole is arranged to operably transmit the liquid material passed through the material buffer chamber toward the flowmeter; a diaphragm, covered on the material buffer chamber; and a fastening element, positioned on the diaphragm and having a hollow portion; wherein when a volume of the liquid material within the material buffer chamber exceeds a predetermined amount, the diaphragm deforms to protrude outward, so that a part of the diaphragm enters the hollow portion of the fastening element.
An example embodiment of a damper device of an automated beverage preparation apparatus is disclosed, comprising: a damper base, comprising a material entrance hole, a material exit hole, and a material buffer chamber located between the material entrance hole and the material exit hole, wherein the material entrance hole is arranged to operably transmit received liquid material to the material buffer chamber, the material buffer chamber is arranged to temporarily store the liquid material flowing into the material buffer chamber, and the material exit hole is arranged to operably output the liquid material passed through the material buffer chamber; a diaphragm, covered on the material buffer chamber; and a fastening element, positioned on the diaphragm and having a hollow portion; wherein when a volume of the liquid material within the material buffer chamber exceeds a predetermined amount, the diaphragm deforms to protrude outward, so that a part of the diaphragm enters the hollow portion of the fastening element.
Both the foregoing general description and the following detailed description are examples and explanatory only, and are not restrictive of the invention as claimed.

As shown in
The quantity of the pumps 110, the damper devices 120, the flowmeters 130, the material output tubes 140, the duck bill valves 150, and the connecting plate 160 shown in
In the automated beverage preparation apparatus 100, a pump 110, a damper device 120, a flowmeter 130, a material output tube 140, and a duck bill valve 150 may be connected by appropriate material transmission pipes and connectors to form a material dispensing device. In this embodiment, the automated beverage preparation apparatus 100 comprises a plurality of material dispensing devices, which are respectively responsible for delivering the liquid materials stored in different material containers 180 to the output terminals of corresponding duck bill valves 150.
In practice, appropriate refrigeration equipment may be installed within the automated beverage preparation apparatus 100 to extend the storage time of various liquid materials.
In order to reduce the complexity of the drawing contents, other structures and devices within the automated beverage preparation apparatus 100 are not shown in
In operations, the user may manipulate the control panel 109 to configure one or more production parameters for the required freshly made beverage, such as beverage item, cup size, beverage volume, sugar level, ice level, and/or quantity of cups, or the like.
Then, the automated beverage preparation apparatus 100 would operate based on the parameters configured by the user to automatically utilize one or more pump 110 to extract the liquid material from one or more material containers 180, and to transmit the extracted liquid material toward corresponding material output tubes 140 through respective transmission pipes. With the continuous operation of respective pump 110, the liquid material within the material output tube 140 will be outputted to the beverage container 190 through corresponding duck bill valve 150.
Freshly made beverage of a variety of favors can be obtained by mixing different liquid materials together in the beverage container 190 according to a particular ratio, or by simple stirring after mixing the liquid materials. In practice, the beverage container 190 may be designed to support or have a blending functionality to increase the speed and uniformity of mixing the liquid materials.
The liquid materials stored in the aforementioned material containers 180 may be liquid materials which have a viscosity higher than water, for example, honey, various syrups, soy milks, nut pulps, fruit juice concentrates, fruit juices containing fruit fibers, tea-based liquids containing small particles (e.g., bubbles or tapioca balls), milk-based liquids, cooking oils, or other thick liquid material and so on.
As described previously, the traditional beverage preparation machines lack appropriate mechanisms to accurately measure the usage amount of the liquid material of the aforementioned type, and thus it usually results in undesirable situations, e.g., the liquid volume of the freshly made beverage does not meet expectation or the taste of the freshly made beverage has bias.
In order to control the liquid volume of the resulting freshly made beverage to be substantially consistent with the parameters set by the user, the automated beverage preparation apparatus 100 would continuously detect the usage amount of respective liquid material during the process of outputting respective liquid material to avoid the situation that the liquid volume of the freshly made beverage does not meet expectation or that the taste of the freshly made beverage has bias due to some liquid materials are outputted too much or insufficient.
It can be appreciated from the foregoing descriptions of
The operation of continuously detecting the usage amount of the liquid material conducted by the automated beverage preparation apparatus 100 during the process of outputting the liquid material will be further described in the following by reference to
In order to reduce the complexity of the drawing contents, only one material dispensing device 400 is shown in
As shown in
The pump 110 comprises a material inlet 412 and a material outlet 414, and arranged to operably pressure the liquid material received through the material inlet 412 to push the liquid material to the material outlet 414. In practice, the pump 110 may be realized with various appropriate liquid pump devices capable of pushing liquid forward, such as a peristaltic pump, a diaphragm pump, a rotary diaphragm pump, or the like.
In this embodiment, the material inlet 412 of the pump 110 may be coupled with the outlet connector 182 of a corresponding material container 180 through appropriate connectors and material transmission pipes (not shown in
The damper device 120 in the material output volume detecting device 402 is arranged to operably conduct a buffering operation on the liquid material flowing through the damper device 120. The damper device 120 comprises a groove-shaped damper base 420, a diaphragm 430, a fastening element 440, and a restriction element 450, wherein the damper base 420 comprises a material entrance hole 421, a material exit hole 423, a material buffer chamber 425, one or more flow guiding elements 427, and a block element 429.
As shown in
The block element 429 is positioned in the material buffer chamber 425, and located in a straight path between the material entrance hole 421 and the material exit hole 423. The block element 429 is arranged to operably prevent the liquid material from directly flowing from the material entrance hole 421 to the material exit hole 423 in a straight line path, to thereby increase the flow resistance of the liquid material when flowing in the damper device 120.
The diaphragm 430 is made by elastic materials and covered on the material buffer chamber 425 of the damper base 420.
The fastening element 440 is positioned on the diaphragm 430, and has a hollow portion 442. The fastening element 440 is arranged to operably press the diaphragm 430 onto the material buffer chamber 425 of the damper base 420 to prevent the liquid material from leaking out. In practice, screws, nails, clamping devices, or other suitable fixing elements may be used to arrange the fastening element 440 above the material buffer chamber 425 of the damper base 420, so that the diaphragm 430 is clamped between the fastening element 440 and the damper base 420.
During the operations of the aforementioned pump 110, the liquid material is intermittently pushed forward, and thus the liquid pressure at the material inlet 412 of the pump 110 exhibits periodic fluctuations. Such a situation will cause the amount of the liquid material flowing into the material buffer chamber 425 to exhibit periodic fluctuations.
When the volume of the liquid material in the material buffer chamber 425 exceeds a predetermined amount (i.e., the nominal volume of the material buffer chamber 425), the diaphragm 430 would deform to protrude outwards, so that a part of the diaphragm 430 enters the hollow portion 442 of the fastening element 440. In this situation, the amount of the liquid material in the damper device 120 will temporarily exceed the nominal volume of the material buffer chamber 425. But after a while, the elastic restoring force of the diaphragm 430 will push the liquid material in the damper device 120 toward the material exit hole 423, so that the amount of the liquid material in the damper device 120 will drop back to a level close to the nominal volume of the material buffer chamber 425.
The restriction element 450 is positioned on the fastening element 440, and arranged to operably restrain the degree of deformation of the diaphragm 430. The restriction element 450 may be realized with a sheet-shaped object, a plate-shaped object, or a block-shaped object with appropriate rigidity, such as an acrylic plate, a metal plate, a metal sheet, or a plastic plate with sufficient thickness. In practice, adhesives, screws, nails, clamping devices, or other appropriate fixing elements may be used to secure the restriction element 450 above the restriction element 450, so that the fastening element 440 and the diaphragm 430 are clamped between the restriction element 450 and the damper base 420.
The flowmeter 130 of the material output volume detecting device 402 is coupled with the output terminal of the damper device 120 (i.e., the material exit hole 423 of the damper base 420), and arranged to operably measure the flow of liquid material output from the damper device 120. In other words, the flowmeter 130 is located at the subsequent stage of the damper device 120. In practice, the flowmeter 130 may be directly connected to the material exit hole 423 of the damper base 420, or may be indirectly connected to the material exit hole 423 of the damper base 420 through a second connector 494 or other appropriate connectors and material transmission pipes (not shown in
The material output tube 140 is coupled with the output terminal of the flowmeter 130, and arranged to operably transmit the liquid material passed through the flowmeter 130. In practice, the material output tube 140 may be indirectly connected to the output terminal of the flowmeter 130 through a third connector 496 with other appropriate material transmission pipes (not shown in
The duck bill valve 150 is coupled with the output terminal of the material output tube 140, and arranged to operably output the liquid material transmitted from the material output tube 140 to the beverage container 190. In practice, the duck bill valve 150 may be directly connected to the output terminal of the material output tube 140, or may be indirectly connected to the output terminal of the material output tube 140 through the aforementioned connecting plate 160 or other appropriate material transmission pipes (not shown in
As described previously, the damper device 120 of the material output volume detecting device 402 conducts a buffering treatment to the liquid material flowing through the damper device 120 with the deformation and elastic restoring force of the diaphragm 430. Accordingly, both the flow speed variation and the liquid pressure variation of the liquid material output from the material exit hole 423 of the damper device 120 will be apparently lower than the flow speed variation and the liquid pressure variation of the liquid material received by the material entrance hole 421 of the damper device 120. Such structure is beneficial for improving the measuring accuracy of the flowmeter 130 in measuring the flow of the liquid material output from the damper device 120, thereby effectively increase the liquid volume control accuracy of the automated beverage preparation apparatus 100 for freshly made beverages.
If the aforementioned damper device 120 is omitted, both the flow speed variation and the liquid pressure variation of the liquid material flowing through the flowmeter 130 will become greater. Such a situation will cause a negative impact to the measuring accuracy of the flowmeter 130 in measuring the flow of the liquid material, thereby reducing the flow measurement accuracy of the flowmeter 130.
In some embodiments, the output portion of the duck bill valve 150 may be realized with appropriate materials with elasticity. Additionally, when the material dispensing device 400 ends the current material output operation, the aforementioned pump 110 may be arranged to operably reverse operation for a predetermined period of time (e.g., 0.3 second, 0.5 second, 0.8 second, 1 second, 1.5 seconds, 2 seconds, etc.) to cause the liquid material in the material dispensing device 400 to flow backward slightly, to thereby generate a negative pressure within the duck bill valve 150, so as to render the output aperture of the duck bill valve 150 to be closed.
As a result, it can effectively prevent the liquid material within the material dispensing device 400 from dripping through the output aperture of the duck bill valve 150 after the material dispensing device 400 ends the current material output operation.
The components and operating mechanism of other material dispensing devices in the automated beverage preparation apparatus 100 are substantially the same as the foregoing material dispensing device 400. For the sake of brevity, similar descriptions will not be repeated here.

In some embodiment, for example, the material output volume detecting device 402 may be instead located at the prior stage of the pump 110. Specifically, the material entrance hole 421 of the damper device 120 may instead be coupled with the outlet connector 182 of a corresponding material container 180 through appropriate connectors and material transmission pipes (not shown in the drawings), so as to receive the liquid material transmitted from the corresponding material container 180. On the other hand, the material inlet 412 of the pump 110 may instead be coupled with the output terminal of the flowmeter 130, so as to receive the liquid material passed through the flowmeter 130. In practice, the material inlet 412 of the pump 110 may be directly connected to the output terminal of the flowmeter 130, or may be indirectly connected to the output terminal of the flowmeter 130 through appropriate connectors or material transmission pipes (not shown in the drawings).
For another example, in some embodiments, the aforementioned block element 429 in the damper base 420 may be modified to be a C-shaped wall element protruding upward from the bottom of the damper base 420, and the opening of the C-shaped wall element may face the material entrance hole 421 or the material exit hole 423. Alternatively, the block element 429 may be designed to have other appearance that can prevent the liquid material from directly flowing from the material entrance hole 421 to the material exit hole 423 in a straight line path.
For another example, in some embodiments, the quantity of the flow guiding element 427 and/or the block element 429 in the foregoing damper base 420 may be increased.
For another example, in some embodiments, the flow guiding element 427 in the foregoing damper base 420 may be omitted.
For another example, in some embodiments, the fastening element 440 and the restriction element 450 may be integrated into a single device by using an integrally forming approach, a 3D printing approach, or other appropriate methods.
For another example, in some embodiments, the foregoing duck bill valve 150 may be replaced with check valve of other types.
It can be appreciated from the foregoing elaborations, by utilizing the disclosed damper device 120 to conduct a buffering operation on the liquid material flowing therethrough, the measurement accuracy of the flowmeter 130 in measuring the flow of the liquid material output from the damper device 120 can be significantly improved, thereby effectively increasing the liquid volume control accuracy of the disclosed automated beverage preparation apparatus 100 for resulting freshly made beverages.
Even if the liquid materials employed by the automated beverage preparation apparatus 100 are liquids having a viscosity higher than water, for example, honey, various syrups, soy milks, nut pulps, fruit juice concentrates, fruit juices containing fruit fibers, tea-based liquids containing small particles (e.g., bubbles or tapioca balls), milk-based liquids, cooking oils, or other thick liquid material and so on, the usage amount of corresponding liquid material can be accurately measured by adopting the structure of the disclosed material output volume detecting device 402.
Accordingly, the disclosed automated beverage preparation apparatus 100 is capable of accurately controlling the material output volume of respective liquid materials, and thus it is enabled to maintain the taste consistency of resulting freshly made beverages.
In addition, the disclosed automated beverage preparation apparatus 100 may operate based on the parameters configured by the user to automatically utilize multiple material dispensing devices to extract and transmit liquid materials multiple material containers 180, and to output the extracted liquid materials to the beverage container 190 through corresponding duck bill valves 150, to thereby achieve the automatic preparation of freshly made beverages. Therefore, the disclosed automated beverage preparation apparatus 100 not only effectively reduces the time and cost required for personnel training, but also significantly reduces the labor time required for involving in the preparation of the freshly made beverages.
