Description

Technical Field

[0001] This invention relates to the field of bartending technology, specifically to an automatically cleaning bartending machine and its control method. Background Technology

[0002] With the continuous development of the economy and society, people's material lives are becoming increasingly affluent, and their spiritual needs are also growing. The consumer base for low-alcohol beverages is gradually expanding, especially among younger generations. Currently, the most popular type of alcoholic beverage is mixed cocktails, such as rum, gin, tequila, and vodka. These are made by using base spirits like rum, gin, tequila, and vodka, combined with other flavoring liquids, and then stirring or shaking. Existing cocktail-making methods are mostly manual, requiring a high level of expertise and incurring high labor costs. Often, the amount of liquid used by the bartender varies, resulting in different flavors. To address this demand, a series of cocktail machines have emerged on the market.

[0003] For example, patent document CN220597404U provides a cocktail machine designed to address the problems of existing cocktail machines being complex in structure and inconvenient to operate, hindering their widespread adoption and failing to meet the needs of ordinary people. This cocktail machine includes: a body; a mixing zone, which from top to bottom includes a base spirit placement zone, a capsule brewing zone, and a liquor mixing zone; a first pipe connects the liquor mixing zone and the base spirit placement zone, and a second pipe connects the liquor mixing zone and the capsule brewing zone; several liquor storage compartments are arranged circumferentially around the base spirit placement zone, and rotating the base spirit placement zone allows different liquors to flow into the first pipe; a stirrer is provided in the liquor mixing zone; and a water / vapor storage zone is located on the body and connected to the capsule brewing zone by a third pipe. This invention has a simple structure, is easy to operate, and allows users to efficiently and cost-effectively make personalized cocktails at home anytime.

[0004] For example, patent document US11820638B2 discloses a beverage preparation apparatus including a cover, a base for supporting at least four bottles, a tower connecting the base and the cover, and a dispenser for dispensing beverages. The cover includes at least four attachment connectors. Liquid from the bottles is selectively pumped through the connectors to the dispenser to dispense the beverage. However, existing cocktail dispensers do not have a cleaning function. Summary of the Invention

[0005] The purpose of this invention is to provide an automatically cleaning cocktail machine and control method, which partially solves or alleviates the above-mentioned shortcomings in the prior art, and can automatically clean the machine using a cleaning system after the beverage is prepared, without the need for manual cleaning.

[0006] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution: A first aspect of the present invention provides an automatically cleanable cocktail mixer, comprising: a piercing device, a stirring mechanism, a piping system, a cleaning system, and a control module, as well as an electronic valve assembly electrically connected to the control module; the stirring mechanism is disposed above the dispensing station, and the piercing device is located above the stirring mechanism and communicates with the piercing device; wherein, The cleaning system includes: a first branch, a second branch, a third water pump installed on the first branch, a first water pump installed on the second branch, and a cleaning liquid tank and a wastewater tank arranged side by side next to the dispensing station; the input end of the first branch is connected to the cleaning liquid tank, multiple storage tanks storing different base spirits, and the outside atmosphere through the electronic valve assembly, and the first output end of the first branch is connected to the capsule compartment in the cocktail mixer; the input end of the second branch is connected to the stirring cup in the cocktail mixer, and the output end of the second branch is connected to the wastewater tank; the third water pump, the air valve of the electronic valve assembly, and the first water pump are all electrically connected to the control module; The piping system includes: a main pipeline located above the cleaning liquid tank and the wastewater tank, a fifth branch pipeline, and a second water pump installed on the fifth branch pipeline. Multiple input terminals of the main pipeline are connected to the electronic valve assembly, and the output terminal of the main pipeline is connected to the input terminal of the first branch pipeline. The input terminal of the fifth branch pipeline is connected to the third output terminal of the first branch pipeline, and the output terminal of the fifth branch pipeline is connected to the stirring cup, thereby forming a base liquor pipeline for supplying base liquor between the first branch pipeline and the fifth branch pipeline.

[0007] Furthermore, the cocktail mixer also includes an acid water tank located above the main pipeline. The pipeline system further includes a fourth branch, the input end of which is connected to the acid water tank, and the output end of which is connected to the mixing cup via a third branch, thereby forming an acid water pipeline for supplying acid water. The third branch is also connected to the second output end of the first branch, and a fourth water pump is installed on the third branch.

[0008] Furthermore, a pipeline level sensor is installed on the fourth branch.

[0009] Furthermore, the main pipeline includes a cleaning pipe section and a base liquor pipe section sequentially connected along the direction close to the stirring mechanism, correspondingly, The electronic valve assembly includes: an air valve disposed at the air inlet of the cleaning pipe section, a first electronic valve disposed at the cleaning liquid inlet of the cleaning pipe section, and a plurality of second electronic valves evenly spaced apart in the base wine pipe section.

[0010] Furthermore, multiple second electronic valves are respectively disposed on both sides of the base wine pipe section; the air valve and the first electronic valve are respectively disposed on both sides of the cleaning pipe section.

[0011] Furthermore, the electronic valve assembly also includes a third electronic valve disposed on the fourth branch; The cocktail machine also includes a display module electrically connected to the control module.

[0012] Furthermore, the piercing device includes: a housing, a base fixedly disposed within a receiving space inside the housing, the base having at least two piercing elements at its bottom; and a cover plate rotatably connected to the top of the housing to cover the receiving space. The puncture device further includes: a capsule chamber disposed within the base and movable up and down along the height direction of the base; at least two capsule chamber bodies are disposed within the capsule chamber; an elastic element is disposed between the capsule chamber and the base; and a through hole is provided at the bottom of the capsule chamber body for the puncture element to extend into. The puncturing member has an axially extending drainage channel that extends through the bottom of the base, and a puncturing end located at the top of the drainage channel for puncturing the capsule. In the initial state, under the action of the elastic element, the capsule chamber is located at the initial height. At this time, the bottom of the capsule chamber body is located above the puncture member, and the puncture end at the top of the puncture member corresponds to the through hole at the bottom of the capsule chamber body. When the cover is opened and at least one capsule is placed into at least one of the capsule chambers, the top of the capsule protrudes beyond the top of the outer shell. When the cover is closed, at least one capsule, under the action of the pressing surface inside the cover, pushes the capsule chamber downward along the axial direction of the drainage channel, thereby allowing the piercing end of the piercing member to extend into the capsule chamber through the through hole and pierce the capsule, so that the liquid inside at least one capsule flows out through the drainage channel. When the cover is opened, the capsule chamber is reset under the action of the elastic element.

[0013] Furthermore, the stirring mechanism includes: a stirring cup with an open top, and a mounting box located at the bottom of the stirring cup, wherein a stirring blade is provided at the bottom of the stirring cup, a driving device for driving the stirring blade is provided in the mounting box, a discharge channel is provided on the side of the bottom of the stirring cup away from the stirring blade, the discharge channel is connected to a wine outlet pipe provided in the mounting box, and the stirring mechanism further includes: a mechanical valve assembly for opening or closing the discharge channel; The mechanical valve assembly includes: an operating rod rotatably disposed within the mounting box and located outside the wine outlet pipeline; a first sealing plug disposed at the inlet of the discharge channel; a transmission rod with one end fixedly connected to the first sealing plug; the other end of the transmission rod extending from the discharge channel into the wine outlet pipeline and passing through the outside of the wine outlet pipeline, and located above the actuating end of the operating rod; a second sealing plug is disposed between the transmission rod and the wall of the bend section of the wine outlet pipeline, and an elastic reset member is disposed at the other end of the transmission rod passing through the wine outlet pipeline; The wine outlet pipeline includes a connecting section, a bending section and a wine outlet section connected in sequence. The connecting section extends axially along the discharge channel, the extension direction of the wine outlet section is parallel to the direction of the connecting section, and the extension direction of the bending section is at an angle α with the extension direction of the connecting section, so that the other end of the transmission rod passes through the bending section. When the operating lever is rotated under an external force, causing the actuator of the operating lever to push the transmission rod to move upward along its axis, the transmission rod drives the first sealing plug to disengage from the inlet of the discharge channel, thereby allowing the liquid in the stirring cup to enter the wine outlet pipe through the discharge channel; When the external force is removed, under the action of the elastic reset member, the transmission rod moves downward along its axis and drives the first sealing plug to close the inlet of the discharge channel.

[0014] Furthermore, the control module is configured to control the opening sequence of each valve in the electronic valve assembly based on a first preset timing control strategy / a second preset timing control strategy, so as to introduce an air column for isolation and cleaning between the extraction of different base wines; The first preset timing control strategy includes: when the previous base wine is extracted, controlling the opening of the air valve to extract cleaning gas through the second water pump to clean the base wine pipeline; and when cleaning is completed, controlling the opening of the second electronic valve corresponding to the next base wine to extract the next base wine. The second preset timing control strategy includes: after the previous base wine extraction is completed, the air valve is opened at time T1 to extract air through the second water pump to clean the base wine pipeline, and then the second electronic valve corresponding to the next base wine is opened at time T2, thereby realizing parallel extraction of base wine; where T2-T1=△t, and △t is the preset delay time.

[0015] A second aspect of the present invention also provides a method for controlling a cocktail machine, comprising the steps of: S11, Obtain a cocktail recipe; the cocktail recipe includes: at least one base spirit, and the extraction order of multiple base spirits and the extraction amount of each base spirit; S12, according to the extraction order, the valves in the electronic valve assembly are opened sequentially, and the second water pump is controlled to extract the corresponding amount of base liquor according to the extraction amount of each type of base liquor; wherein, after each type of base liquor is extracted, the air valve in the electronic valve assembly and the second electronic valve for the next extraction of base liquor are opened based on the first preset timing control strategy / second preset timing control strategy, thereby forming an air isolation column in front of the base liquor in the base liquor pipeline; S15, control the stirring mechanism to start stirring, and after the prepared beverage is discharged, control the first electronic valve to open, and control the third water pump to draw cleaning liquid from the cleaning liquid tank to clean the capsule chamber and puncture parts; S16, control the stirring mechanism to start stirring for cleaning, and when cleaning is completed, control the first water pump to discharge the cleaning liquid in the stirring mechanism.

[0016] Beneficial effects: Current technologies lack a cleaning function for cocktail machines, requiring manual cleaning, which significantly degrades the user experience. Replacing one of the multiple storage containers for base spirits with a cleaning solution bottle and then drawing the solution reduces the variety of base spirits available, thus limiting the number of drinks that can be prepared – essentially sacrificing drink variety for the cleaning function. Even replacing the storage container with the cleaning solution tank after mixing drinks maintains the same variety, but still requires manual replacement, greatly reducing cleaning efficiency and user experience. This application, however, integrates a cleaning solution tank into the cocktail machine, allowing cleaning to begin immediately after mixing, eliminating the need for manual cleaning or replacing the base spirit bottle with the cleaning solution.

[0017] In this application, the internal space of the bartender's base is fully utilized to integrate the cleaning liquid tank and wastewater tank of the cleaning system into the base (or shell). Above the cleaning liquid tank and wastewater tank within the base, a piping system (including various branches of the cleaning system, as well as pipes for conveying base liquor, pipes for conveying acidic water, etc.) and an acidic water tank are integrated. Through optimized piping design (e.g., the pipes for conveying base liquor to the stirring cup and the pipes for conveying clean water to the puncture device share some branches; or, through the combination of four-way and three-way connectors, the various branches connected to the stirring cup can be cleaned using cleaning gas / liquid), the bartender can achieve automatic cleaning without sacrificing the ability to adjust the types of drinks, and without significantly increasing the size of the bartender.

[0018] In the bartending process described in this application, the amount of each ingredient, such as the base spirit and the acid solution, is fixed. If the amount of any ingredient is insufficient, the final taste of the bar may differ from the desired taste. Therefore, to avoid the base spirit (or acid solution) remaining in the pipes during the mixing process, which could lead to insufficient amounts of ingredients entering the mixing cup or cause interference (e.g., counting the residual amount of the previous ingredient as the amount of the current ingredient), resulting in a lack of flavor in the final product, this application proposes a control method for a bartending machine. This method involves immediately cleaning the pipes with a cleaning gas, such as air (or other cleaning gases), after each ingredient required for mixing, such as the base spirit, thereby reducing the amount of residual liquid in the pipes.

[0019] Furthermore, the control method of the cocktail mixer in this application controls the timing between the extraction of cleaning gas, such as air, and the extraction of the next component, thereby creating an air column before the extraction of the next component. For example, by first extracting air and then delaying the extraction of the next component, the next base liquor component and the air column formed by the cleaning gas in the pipeline (the air column in this document includes a section of gas column formed by various cleaning gases in the pipeline) are simultaneously present in the pipeline, thereby cleaning the residue while preventing pre-mixing between different components, such as different base liquors. Moreover, by dividing the system into a first branch (supply / cleaning), a second branch (wastewater discharge), a third / fourth branch (acidic water supply), and a fifth branch (base liquor supply), functional decoupling is achieved, greatly reducing the cross-contamination paths between different liquids (base liquor, acidic water, cleaning liquid).

[0020] The cocktail mixer in this application innovatively integrates three major functions—a piercing device, a stirring mechanism, and a cleaning system—into one unit, with the cleaning system built into the base of the machine. Through the arrangement of its internal structure, the traditionally bulky and disorganized cocktail mixer achieves a more compact and efficient space utilization. Furthermore, the entire cocktail mixer has no exposed redundant pipes or separate components, presenting a clean and integrated appearance.

[0021] The cocktail mixer described in this application features an integrated design that combines capsule puncturing, stirring, and cleaning functions. Thanks to its cleaning system, users can clean the internal tubing without disassembling any parts. This integrated design achieves miniaturization while freeing users from repetitive cocktail-making procedures, significantly improving the cocktail mixer's portability. Attached Figure Description

[0030] In this article, "multiple" means two or more, that is, it includes two, three, four, five, etc.

[0032] Example 1: Existing cocktail piercing devices require manual pressing of each capsule one by one (e.g., CN214457855U, CN220597404U). When multiple capsules are needed simultaneously, multiple pressings are required, making the operation cumbersome and inefficient. Therefore, this application proposes a piercing device that eliminates the need for manual pressing of each capsule, simplifies operation, and ensures consistent force applied to each capsule. The following detailed description, in conjunction with specific embodiments and accompanying drawings, provides further details.

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a piercing device for a cocktail machine, including: a housing, the housing having an internal accommodating space, and a base 2 fixedly disposed on the inner wall of the accommodating space, the base 2 having at least two piercing elements 4 at its bottom; and a cover plate 3 rotatably connected to the top of the housing to cover the accommodating space.

[0034] In some embodiments, the puncture member 4 is fixed to the bottom of the base 2 (e.g., the puncture member 4 is integrally formed with the base 2, or connected by welding or other fixing methods), or the puncture member 4 is detachably connected to the bottom of the base 2 (e.g., by magnetic connection, snap-fit ​​connection, or fastening by bolts or other fasteners).

[0035] In this embodiment, the puncture device further includes: a capsule chamber 1 disposed within the base 2 and movable vertically along the height direction of the base 2 (i.e., the capsule chamber 1 is liftable), wherein at least two capsule chamber bodies 103 are disposed within the capsule chamber 1, and an elastic member 6 is disposed between the capsule chamber 1 and the base 2; the bottom of the capsule chamber body 103 is provided with a through hole 101 into which the puncture member 4 can extend. The puncture member 4 has an axially extending drainage channel 401 that penetrates the bottom of the base 2, and a puncture end 402 located at the top of the drainage channel 401 for puncturing the capsule and extending axially along the drainage channel 401.

[0036] like Figure 3 As shown, the working principle of this puncture device is as follows: In the initial state, under the action of the elastic member 6, the capsule chamber 1 is located at an initial height H1. At this time, the bottom of the capsule chamber body 103 is above the piercing member 4, and the piercing end 402 at the top of the piercing member 4 corresponds to the through hole 101 at the bottom of the capsule chamber body 103. The piercing end 402 corresponding to the through hole 101 at the bottom of the capsule chamber body 103 ensures that the piercing end 402 can extend into the capsule chamber body 103. This allows the piercing end 402 at the top of the drainage channel 401 to directly penetrate the through hole 101 and extend into the capsule chamber body 103, or to be located inside the capsule 102 placed inside the capsule chamber body 103, when the capsule chamber 1 moves downward. For example, the through hole 101 is axially aligned with the drainage channel 401, but there is a certain gap between the piercing end 402 and the through hole 101, or part of the piercing end 402 extends into the through hole 101. Of course, it does not have to be axially aligned, as long as it can satisfy the requirement that when the capsule chamber 1 moves downward, the piercing end 402 at the top of the drainage channel 401 can directly penetrate the through hole 101 and extend into the capsule chamber body 103, or be located in the capsule 102 placed in the capsule chamber body 103.

[0037] When the cover plate 3 is opened, at least one capsule 102 (such as...) Figure 3 As indicated by the arrow, when capsule 102 is placed into capsule chamber 1, and at least one of the capsule chamber bodies 103 is placed inside, the top of the capsule protrudes beyond the top of the outer shell. When the cover plate 3 is closed, at least one capsule, under the action of the pressing surface 301 inside the cover plate 3, pushes the capsule chamber 1 downwards along the axial direction of the drainage channel. This allows the piercing end of the piercing member 4 to extend through the through hole into the capsule chamber body and pierce the capsule, allowing the liquid inside at least one capsule to flow out through the drainage channel. See [reference needed]. Figures 5A-5E .

[0038] See Figure 3 When the cover plate 3 is opened, the capsule chamber 1 returns to its initial height under the action of the elastic member 6.

[0039] For example, see Figure 3 In the initial state, capsule compartment 1 is located at the initial height H1. After opening the cover plate 3, at least one capsule is placed in at least one capsule compartment body (i.e., one capsule is placed in each capsule compartment body). At this time, the weight of the capsule does not affect the height change of capsule compartment 1 (even if there is a small change, it can be ignored). Therefore, the height of capsule compartment 1 is still the initial height H1, and the top of the capsule protrudes outside the top of the outer shell. That is, the height of the top of the capsule relative to the top of the outer shell is the second height H2.

[0040] During the closing of the cover plate 3, under the action of the pressing surface 301 on the inner side of the cover plate 3, the capsule pushes the capsule chamber 1 downward along the axial direction of the drainage channel (that is, along the axial extension direction of the capsule chamber body), that is, the capsule chamber moves towards the piercing member 4, so that the piercing end of the piercing member 4 extends into the capsule chamber body through the through hole and pierces the capsule, and then extends into the capsule; and when the cover plate 3 is completely closed, the capsule chamber 1 descends to the third height H3 (that is, the capsule chamber 1 descends from the first height H1 to the third height H3), and correspondingly, the height of the top of the capsule relative to the top of the outer shell also descends from the second height H2 to the fourth height H4. Among them, the descending height of the capsule chamber 1 and the capsule, that is, H1-H3 or H2-H4, is actually the length of the piercing member 4 extending into the capsule chamber body / capsule (ignoring the thickness of the bottom of the capsule chamber body and the thickness of the bottom of the capsule). In other words, through the linkage between the cover plate 3, the capsule chamber, and the capsules, multiple capsules are punctured almost simultaneously (in practical applications, the time difference between punctures between capsules is negligible); and the length of the puncturing element extending into the capsule is almost equal to the descent height of the capsule chamber. Therefore, ensuring the descent height of the capsule chamber is sufficient to guarantee complete puncture of the capsules. Preferably, the descent height of the capsule chamber is much greater than the height of the puncturing end, see [reference needed]. Figures 5B-5E .

[0041] like Figure 3 As shown, the initial height H1 and the third height H3 mentioned above are both referenced to the bottom of the base 2 fixed to the outer shell. That is, the descent of the capsule compartment from the initial height H1 to the third height H3 refers to the change in height of the bottom of the capsule compartment relative to the bottom of the base 2. Of course, in some other embodiments, the change in height of the top of the capsule compartment relative to the bottom of the base 2 can also be used to represent this. Naturally, the reference datum can also be changed according to actual needs.

[0042] like Figure 3 As shown, the second height H2 and the fourth height H4 mentioned above are both referenced to the top of the outer shell fixed to the bartender's frame. That is, the descent of the capsule from the second height H2 to the fourth height H4 refers to the change in height between the top of the capsule and the inner pressing surface of the lid, relative to the top of the outer shell. Of course, this reference point can be changed according to actual needs.

[0043] In some embodiments, the inner side of the cover plate 3 includes a flat bottom at the center and an inclined surface surrounding the flat bottom, thereby forming a recessed space on the inner side of the cover plate for accommodating a capsule protruding from the outer shell, and the flat bottom of the recessed space serves as an inner pressing surface acting on the capsule. Preferably, the cross-section of the inner side of the cover plate 3 has a V-shaped structure with the tip truncated.

[0044] In this embodiment, since other parts need to be installed inside the cover plate 3, such as water supply components (such as sprinkler heads), pipes and other different components in subsequent embodiments, if all of them adopt a flat bottom design and cancel the surrounding inclined surface design, the installation space inside the cover plate will be greatly reduced, which may result in the inability to install pipes and other components.

[0045] Specifically, the capsule body 103 has at least two puncture elements, and correspondingly, the base is provided with at least two puncture elements corresponding to the through holes at the bottom of the capsule body. Preferably, the capsule body 103 has five puncture elements, and correspondingly, the base 2 is provided with five puncture elements 4 corresponding to the through holes at the bottom of each capsule body.

[0046] In this application, the puncture component is concealed at the bottom of the capsule chamber, effectively avoiding the problems of dust accumulation or bacterial growth caused by long-term exposure. Furthermore, the entire process from capsule puncture to the liquid flowing into the next stage is completed within a closed space, reducing the contact between the liquid and outside air. On the other hand, when the cover is opened, the capsule chamber automatically springs back after losing pressure, separating the puncture end from the capsule. This facilitates the smooth dripping of any residual liquid from the puncture component, preventing blockages or spoilage caused by long-term residue. Moreover, the drainage channel is integrated with the puncture end, eliminating the need for separate separation springs, needles, or other components for each capsule, reducing mold costs and simplifying later maintenance. Furthermore, in this embodiment, a technical approach combining a lifting capsule chamber with a fixed puncture component is adopted, that is, a combination of a "static puncture component" and a "dynamic capsule chamber", rather than a technical approach that uses a movable "dynamic puncture component" to move towards the "fixed capsule chamber" for puncturing. Therefore, there is no need to set up a corresponding drive structure for each puncture component, the structure is simpler, there are fewer parts, it is more suitable for the lightweight design of cocktail machines, and because there are fewer parts, the installation process is simpler and the failure rate is lower.

[0047] In some embodiments, a trigger 201 is built into the side of the cover plate 3 away from its pivot axis, and correspondingly, a sensor body 202 (i.e., a sensing element) is built into the top of the housing at a position corresponding to the trigger 201. By configuring the cooperation between the trigger 201 and the sensor body 202, it is possible to detect whether the cover plate 3 is closed on the top of the housing. For example, in this embodiment, the sensor body and the trigger are a Hall sensor and a magnet, respectively, and a corresponding prompt can be given when it is detected that the cover plate 3 is not closed properly.

[0048] In some embodiments, a counterweight 303 is provided inside the cover plate 3 to ensure that the cover plate 3 can better securely close to the top of the capsule compartment. See [reference needed]. Figure 5G .

[0049] In some embodiments, if the height to which the capsule descends is greater than the height of the puncture end 402, then, in order to ensure that most of the liquid inside the capsule can enter the stirring mechanism below through the drainage channel 401 within the puncture member 4, specifically, see... Figure 5D The longitudinal section of the piercing end 402 at the top of the piercing member 4 is a right-angled triangle, which makes the inlet at the top of the piercing member 4 inclined. This allows liquid at the bottom of the capsule to enter the drainage channel 401 inside the piercing member 4 through the lower end of the inclined inlet when the piercing end 402 enters the capsule, thus flowing into the stirring mechanism below. Furthermore, multiple inclined through holes 403 communicating with the drainage channel 401 can be inclinedly provided on the side wall of the piercing member 4, so that liquid at the bottom of the capsule can also enter the drainage channel 401 inside the piercing member 4 through the lower end of the inclined inlet, thus flowing into the stirring mechanism below. See [reference needed]. Figure 5F .

[0050] In some embodiments, the outer shell is provided with a limiting member 5 for limiting the position of the capsule chamber 1. By providing the limiting member 5, the distance (if any) between the through hole at the bottom of the capsule chamber body and the piercing end at the top of the piercing member 4 is sufficiently small in the initial state, thereby ensuring that after the cover plate 3 is closed, the piercing member is aligned with the through hole, and also ensuring that the piercing end at the top of the piercing member extends sufficiently into the capsule. For example, see Figure 1 and Figure 2 A limiting element 5 can be provided on the rotating shaft, or a limiting element 5 can be provided on the top of the housing.

[0051] In some embodiments, a water supply component 302 is provided on the cover plate 3 corresponding to each capsule body, see [link to relevant documentation]. Figure 5C The water supply component is connected to a water storage tank (or a cleaning solution tank for storing cleaning solution) via a clean water pipe 8, and a water pump is installed on the clean water pipe 8. Preferably, the water supply component 302 is a spray head or a shower head.

[0052] When the cover plate 3 is closed on the top of the outer shell, each water supply component 302 is located above each capsule compartment body, so that when the capsule 102 inside the capsule compartment body is removed, the puncture part 4 below the corresponding capsule compartment body 103 can be cleaned through the water supply component 302.

[0053] In some embodiments, the cocktail mixer includes a stirring cup 14 disposed below the base 2, and the drain pipe 401 is connected to the stirring cup 14.

[0054] Specifically, a docking chamber 9 for engaging with the stirring cup 14 is provided below the base 2, and a fastening end 901 is provided around the docking chamber 9. Correspondingly, a buckle 902 that can engage with the fastening end 901 is provided on the outer wall of the stirring cup, thereby connecting with the puncture device. The liquid after the capsule is punctured flows into the stirring cup below through the drainage channel.

[0055] In some embodiments, the elastic element 6 is a spring. The spring is disposed in the elastic element mounting groove 203 in the base 2. A limit block is provided on the side wall of the capsule chamber 1. One end of the spring abuts against the limit block, and the other end abuts against the bottom of the elastic element mounting groove 203. When the capsule chamber 1 is subjected to external pressure, the capsule chamber 1 moves downward along its axial direction, at which time the spring is compressed. When the external pressure is removed, the capsule chamber 1 returns to its original position under the action of the spring. See [reference needed]. Figure 1 .

[0056] In some embodiments, the base 2 is fixed within the receiving space of the housing by a fastener 7. Exemplarily, the fastener 7 may be a fixing pin or bolt, etc.

[0057] In some embodiments, the puncture end of the puncture member 4 is a tapered cone or wedge shape. Preferably, the top of the drainage channel 401 is set as a pointed tip with a cone or wedge-shaped cross-section, thereby forming an annular puncture end 402. Therefore, the contact area between the puncture member 4 and the capsule is larger during puncture, and the puncture opening is adapted to the size of the drainage channel. Compared with needles or other puncture shapes, the cone or wedge shape facilitates puncturing the capsule, and the liquid after puncturing the capsule flows along the puncture end into the drainage channel of the puncture member. Furthermore, the size of the puncture opening is adapted to the size of the drainage channel, resulting in a higher flow rate compared to puncture openings formed by traditional puncture needles and other structures, thereby improving the efficiency of cocktail preparation to a certain extent. See [link to relevant documentation]. Figure 5D and Figure 5E .

[0058] In some embodiments, the cover plate 3 is rotatably connected to the outer casing via rotational damping. Specifically, in this embodiment, the rotational damping is provided on a rotating shaft, which allows the cover plate to be opened to any angle around the rotating shaft.

[0059] In this embodiment, a liftable capsule chamber is provided, and a puncturing device with a drainage channel is provided below each capsule chamber. A flip-up cover is also provided. When the cover is opened and capsules of different flavors are placed in multiple capsule chambers, the capsules protrude from the capsule chamber. Therefore, when the cover is closed, the cover presses the tops of multiple capsules almost simultaneously (although there is a certain distance between each capsule, the distance is small, and the inner pressing surface of the cover acts on each capsule almost simultaneously during the pressing process). This causes the entire capsule chamber to move downward together, so that the puncturing end of the puncturing device punctures the corresponding capsule. That is, the height of the protruding capsule (higher than the capsule chamber) is cleverly used as the transmission point. No additional sensors or complex electronic components are required. The mechanical linkage of the cover, capsule chamber and puncturing device is achieved by pure mechanical structure, so as to realize the synchronous puncturing of multiple capsules. The operation is simple (that is, there is no need for the "press-wait-rebound" operation of each capsule as in the prior art. Just put in the capsule and close the cover at once to complete the synchronous puncturing of all capsules) and highly efficient. Furthermore, since the inner pressing surface of the cover plate presses down on the tops of multiple capsules simultaneously, ensuring that each capsule is subjected to uniform force and has a consistent descent stroke, all capsules are punctured simultaneously and completely, avoiding the problem of incomplete puncture due to uneven pressing.

[0060] The puncture device is hidden at the bottom of the capsule compartment, effectively avoiding the problems of dust accumulation or bacterial growth caused by long-term exposure. Furthermore, the entire process from capsule puncture to the liquid flowing into the next stage is completed within a closed space, reducing the contact between the wine and the outside air.

[0061] Furthermore, when the cover is opened, the capsule chamber automatically springs back after losing pressure, separating the puncture end from the capsule. This helps residual liquid in the puncture part to drip smoothly, avoiding blockage or spoilage caused by long-term residue. In addition, the drainage channel is integrated with the puncture end, eliminating the need for separate separation springs, needles, and other parts for each capsule, reducing mold costs and the difficulty of later maintenance.

[0062] Example 2: Existing cocktail mixers generally employ two methods for discharging the mixing mechanism: active extraction using a water pump and electronic valves installed in the discharge channel. The active extraction method results in a more complex overall structure, requiring an additional water pump, which increases manufacturing costs and occupies installation space, hindering miniaturization design. Electronic valves, whether solenoid or electric ball valves, typically have complex flow channels, valve core cavities, or sealing gaps. Prepared drinks contain viscous substances such as sugar, which can easily accumulate, dry, and breed bacteria in the dead corners inside the valve, and are difficult to clean thoroughly with simple rinsing. Therefore, existing technologies propose using plugs to open / close the discharging pipeline. For example, utility model patent CN208917152U discloses a mixing and cleaning device for a self-service cocktail machine, comprising: a mixing tank installed at the center of a first tray, the inner cavity of which is connected to the outlets of all discharge solenoid valves in the self-service cocktail machine via discharge pipes; a discharge port is provided at the bottom of the mixing tank; and a mixing drive mechanism installed at the center of a second tray. This patent document uses a discharge plug to open and close the mixing tank, i.e., a mechanical sealing method. However, in this solution, the discharge plug is integrated with the mixing mechanism, and even when mixing is not required, a motor needs to be started to drive its lifting and lowering to open and close the discharge channel. This not only increases manufacturing costs but also, due to its complex structure and numerous drive devices, hinders the miniaturization of the cocktail machine. Therefore, this application provides a new mixing mechanism, which will be described in detail below with reference to specific embodiments and accompanying drawings.

[0063] like Figure 6 , Figure 7 and Figure 10 As shown, this embodiment provides a stirring mechanism for a cocktail mixer, including: a stirring cup 14 with an open top, a stirring blade 15 at the bottom of the stirring cup 14, and a driving device 19 disposed outside the stirring cup 14 for driving the stirring blade 15 (preferably, a mounting box 20 is disposed below the stirring cup 14 for mounting the driving device 19). A discharge channel 22 is disposed on the side of the bottom of the stirring cup 14 away from the stirring blade 15, and the discharge channel 22 is connected to a liquor outlet pipe 16 (preferably, the liquor outlet pipe 16 is disposed inside the mounting box 20). The stirring mechanism further includes: a mechanical valve assembly 17 for opening or closing the discharge channel 22.

[0064] Specifically, the drive device 19 can be a motor, and the output shaft of the motor is connected to the stirring blade 15 for transmission. Exemplarily, the drive device (motor) and the connected stirring blade 15 are coaxially mounted at the bottom center of the stirring cup 14. The stirring blade 15 has a structure in which its radially opposite two edge portions are bent upwards, and its middle portion is concave downwards relative to the two end portions; that is, the cross-section of the stirring blade 15 has a bowl-like arc-shaped working surface. See [reference needed]. Figure 8 .

[0065] In some embodiments, the mechanical valve assembly 17 includes: an operating rod 170 rotatably disposed within the mounting housing 20 and located outside the wine outlet pipe 16; a first sealing plug 171 disposed at the inlet of the discharge channel 22; a transmission rod 172 fixedly connected at one end to the first sealing plug 171; the other end of the transmission rod 172 extends from the discharge channel 22 into the wine outlet pipe 16 and passes through the outside of the wine outlet pipe 16, and is located above the actuating end 1701 of the operating rod 170; a second sealing plug 173 is disposed between the transmission rod 172 and the wall of the bent section of the wine outlet pipe 16; and an elastic reset member 21 is disposed between the other end of the transmission rod 172 passing through the wine outlet pipe 16 and the actuating end 1701 of the operating rod 170.

[0066] According to ergonomics, it is generally desirable to separate the operating surface from the dispensing port. If the operating surface and the dispensing port are on the same side, such as a faucet-style switch, the user's hand needs to keep pressing the operating switch because the container is also below the switch, which may obstruct the user's view, requiring them to turn to the side or bend over to see the amount of beverage in the container. Therefore, in this embodiment, through structural design, the operating surface (i.e., the surface directly operated by the user's hand) is separated from the dispensing port. For example, the operating switch (such as operating end 1702) controlling the dispensing pipe 16 is located on the side of the device facing the user, such as the front side of the stirring cup facing the user, thus facilitating user operation. The dispensing port of the dispensing pipe 16 is located at the bottom of the device, such as the bottom of the stirring cup. This allows the user to directly place the container holding the beverage on the dispensing station below the dispensing port, and because there is no obstruction, the amount of beverage in the container can be seen more intuitively. Furthermore, the faucet-style switch on the side wall makes it impossible to completely empty the beverage in the stirring cup, or results in a large amount of residue; while in this application, the dispensing port is directly located at the bottom of the stirring cup, greatly reducing the amount of residue in the stirring cup. Furthermore, the bottom of the mixing cup can be tilted to create a depression at the discharge port, which helps with emptying.

[0067] In this embodiment, the mechanical valve assembly 17 is configured as a switch for the beverage outlet channel after stirring, so as to meet the requirement of the beverage (such as wine) being opened and closed immediately. The outlet channel 22 is located at the bottom of the stirring cup and is connected to the wine outlet pipe 16. The mechanical valve assembly controls the opening and closing of the outlet channel, so that the fully stirred beverage, such as wine, flows out through the wine outlet pipe 16. Specifically, when an external force is applied to the operating end 1702 of the operating lever, the execution end 1701 of the operating lever 170 moves upward along the direction of the transmission rod 172, thereby driving the transmission rod 172 to move upward along its axial direction. At this time, the first sealing plug 171 connected to one end of the transmission rod 172 moves upward, thereby opening the inlet of the discharge channel 22 which was closed by the first sealing plug 171, allowing the beverage in the stirring cup to flow into the wine outlet pipe 16 from the inlet of the discharge channel. When the external force acting on the operating end 1702 of the operating lever 172 is removed, under the action of the elastic reset member 21, the transmission rod 172 moves downward along its axial direction, causing the first sealing plug 171 to close the discharge channel 22. See [link to relevant documentation]. Figure 12 and Figure 13 .

[0068] The wine outlet pipe 16 includes a connecting section 1601, a bending section 1602, and an outlet section 1603 connected in sequence. The connecting section 1601 extends axially along the discharge channel 22. The outlet section 1603 extends in a direction parallel to the connecting section 1601 (wherein the outlet section 1603 is closer to the drive device 19, while the connecting section 1601 is farther from the drive device). The bending section 1602 and the outlet section 1603 have an angle α between their extension directions, allowing the other end of the transmission rod 172 to pass through the bending section 1602. (See also...) Figure 8 Specifically, the axial directions of the connecting section 1601 and the dispensing section 1603 are parallel to the axial direction of the transmission rod 172, while the bending section 1602 connects the connecting section 1601 and the dispensing section 1603, and the inlet of the connecting section 1601 is connected to the outlet of the discharge channel 22; the angle between the axial direction / extension direction of the bending section 1602 and the axial direction / extension direction of the connecting section 1601 / dispensing section 1603 is an acute angle. In particular, an acute angle refers to the angle α between the wall of the bending section and the extension direction of the wall of the dispensing section being an acute angle.

[0069] The working principle of the stirring mechanism in this embodiment is as follows: In the initial state, the first sealing plug 171 is pressed against the inlet of the discharge channel 22, so that the discharge channel 22 is in a normally closed state, and the liquid in the stirring cup 14 is sealed inside the cup. See Figure 13 .

[0070] When the operating lever 170 is rotated under external force, the actuator 1701 of the operating lever 170 forms a driving engagement with the transmission lever 172, pushing the transmission lever 172 to overcome the resistance of the elastic reset member 21 and move upward along its axial direction. As the transmission lever 172 rises, it simultaneously drives the first sealing plug 171 to move upward, causing it to disengage from the discharge channel 22. This opens the inlet of the discharge channel 22, which was sealed by the first sealing plug 171. Under the action of gravity, the liquid in the stirring cup enters the wine outlet pipe 16, which is connected to the opened discharge channel 22, thus achieving liquid discharge. (See also...) Figure 12 .

[0071] When the external force is removed, under the action of the elastic reset member 21, the transmission rod 172 moves downward along its axis, and drives the first sealing plug 171 to press against the inlet of the discharge channel 22 again, cutting off the liquid outlet pipe and making the inlet of the discharge channel 22 re-sealed. Of course, the operating rod 170 also resets at this time.

[0072] In this application, the stirring blade is integrated into the bottom of the stirring cup, and a drive device for rotating the stirring blade is provided below the stirring cup. This allows the puncture device to be directly installed above and connected to the stirring mechanism, eliminating the need for additional piping to transport the flavor component liquid from the capsule in the puncture device to the stirring cup. Furthermore, since the drive device for driving the stirring blade is located below the stirring cup, the space below the stirring cup is limited. Therefore, it is necessary to consider more rational use of the space below the stirring cup to simultaneously install the discharge channel, mechanical valve assembly, and the aforementioned drive device. Thus, the stirring mechanism of this application adopts the aforementioned three-section wine discharge pipeline, which avoids the operating rod 170 and the transmission rod 172, so that only part of the transmission rod 172 is located in the wine discharge pipeline 16, thereby not significantly occupying the area in the wine discharge pipeline and reducing the wine discharge efficiency. It is also easier to clean and maintain, and the device is more ergonomic.

[0073] In this design, the drive rod 172 only "pierces" through the pipe wall, meaning it is partially located within the dispensing pipe 16. Compared to a design where the entire drive rod is located within the dispensing pipe, this reduces flow resistance, thereby ensuring the speed and smoothness of dispensing from the mixing cup. This is especially important for cocktail-making scenarios requiring rapid dispensing (e.g., bars or parties), where the cocktail machine needs to dispense drinks continuously and quickly. The low-resistance piping in this application ensures the dispensing speed.

[0074] Furthermore, the three-section dispensing pipe's avoidance design allows the operating rod 170 and the elastic reset element 21 to be located outside the dispensing pipe, significantly reducing the sealing difficulty. For example, if the operating rod is inserted into the axially extending dispensing pipe, the entire transmission rod and sealing plug would be located within the dispensing pipe. However, since the operating rod is rotatable, it is necessary to consider not only the seal between the first sealing plug and the stirring cup outlet (dynamic seal), but also the seal between the operating rod and the dispensing pipe during rotation. In this application, only the seal at the first sealing plug (dynamic seal) and the seal between the transmission rod and the bent section (static seal) need to be considered.

[0075] Because the space below the stirring cup is limited (for example, the space inside the mounting box 20 is limited), and other components such as the drive device (motor) and the rotating connecting rod 170 need to be installed in this limited space, the design of the above-mentioned bending section not only allows the operating rod 170 to be installed in the limited space, but also allows the wine outlet section to be directed to the space between the drive device (motor) and the operating rod through the bending section, making the structure compact, thereby improving space utilization and helping to achieve miniaturization.

[0076] In some embodiments, the length of the connecting section 1601 is less than the length of the bent section 1602, and the length of the bent section 1602 is less than the length of the dispensing section 1603. The connecting section 1601 extends axially along the dispensing channel 22, but is the shortest. This means the distance from the bottom of the stirring cup's outlet to the starting point of the bend is extremely short, allowing the drive rod 172 to be vertically positioned through the bent section 1602, resulting in a shorter vertical stroke of the drive rod 172 within the dispensing channel 22. If the connecting section 1601 is too long, with the other two sections remaining constant, on the one hand, the drive rod 172 requires a longer vertical stroke to reach the position where it contacts the operating lever 170, increasing the overall height of the machine, and the long lever arm can cause the drive rod 172 to wobble easily during lifting and lowering; on the other hand, a longer drive rod 172 within the dispensing channel 22 may affect the dispensing speed. In other words, the shorter connecting section 1601 allows the fulcrum of the transmission rod 172 to be closer to the bottom of the stirring cup, shortening the lever arm and making the lifting and lowering action of the transmission rod more stable, as well as the opening and closing of the first sealing plug 17 more stable. The longer bending section than the connecting section means there is sufficient axial distance between the transmission rod's penetration point and the operating rod's contact point to accommodate the compression / extension stroke of the reset component. Simultaneously, sufficient lateral span is provided, allowing the rotation center of the operating rod to be set away from the center of the stirring cup bottom, facilitating user operation and preventing spatial overlap between the operating rod and other components such as the stirring cup and motor. In other words, the three-section decreasing length design achieves functional separation and spatial coexistence of the wine outlet channel and the transmission-reset mechanism within the extremely limited space below the stirring cup. This allows the transmission rod to pass through the bending section and link with the operating rod, while the elastic reset component obtains independent installation space. All components are in their proper positions and do not interfere with each other, ultimately achieving a compact, reliable, and easy-to-operate miniaturized stirring mechanism. Preferably, when an external force is applied to the operating lever, the penetration point of the bending section of the operating lever is located in the middle of the operating lever.

[0077] In some embodiments, the angle between the axial or extending direction of the bent segment and the axial or extending direction of the connecting segment is 10°-85°. Preferably, it is 30°-55°; more preferably, it is 35°, as this angle is more conducive to the rapid flow of the liquid.

[0078] In some embodiments, a docking channel is provided on the top of the mounting box 20, in which the outlet of the discharge channel 22 and the inlet of the wine discharge pipeline 16 are docked, and a seal is provided between them. This method provides a simple sealing solution.

[0079] like Figure 9As shown, in some embodiments, the stirring mechanism further includes: an ice-blocking net that can be placed over the stirring blade 15; the ice-blocking net includes: an ice-blocking net surface 18 that cooperates with an annular cooling component (e.g., a pre-frozen stainless steel annular component, which is less prone to shaking than ice blocks), and a plurality of support members 24 evenly spaced along the edge of the ice-blocking net surface 18, the extending direction of the support members 24 being parallel to the central axis of the ice-blocking net surface 18, such that the plurality of support members 24 and the ice-blocking net surface 18 enclose a receiving space for accommodating the stirring blade 15 (in other embodiments, the extending direction of the support members 24 has a certain angle with the central axis of the ice-blocking net surface 18, such as an obtuse angle, i.e., it only needs to enclose a receiving space for accommodating the stirring blade); correspondingly, a plurality of limiting grooves that engage with the support members 24 are provided on the inner wall of the stirring cup 14, see Figure 11 .

[0080] When the support member 24 is installed in the limiting groove, the stirring blade 15 is located within the receiving space. At this time, multiple support members 24 surround the stirring blade 15, and the ice-blocking mesh 18 is located above the stirring blade 15. (See also...) Figure 15 and Figure 14 .

[0081] In some embodiments, the ice-blocking mesh surface 18 includes an annular body 1801 and a spherical protrusion 1802 located in the middle of the annular body 1801 and connected to the annular body 1801 for cooperating with the annular cooling element; a plurality of ice-blocking mesh through holes 1803 are uniformly spaced on the annular body 1801 and the spherical protrusion 1802. The ice-blocking mesh through holes 1803 are provided to reduce the influence of the ice-blocking mesh on the stirring, thereby maintaining the spiral flow field generated by the stirring blades and reducing ineffective kinetic energy loss.

[0082] Preferably, the area covered by the projection of the spherical protrusion 1802 onto a horizontal plane (such as the plane where the bottom of the stirring cup is located) is greater than or equal to the projection of the stirring blade onto the same horizontal plane (such as the plane where the bottom of the stirring cup is located). More preferably, the diameter of the ice-blocking mesh through-hole 1803 on the spherical protrusion is greater than the diameter of the ice-blocking mesh through-hole on the annular body 1801. The spherical protrusion is located in the center region of the vortex, where the fluid velocity is usually high, and the larger aperture can further reduce the cutting and obstruction of the high-speed water flow in the center; while the annular body is close to the cup wall, and the smaller aperture also results in relatively less resistance to the fluid flowing back along the cup wall.

[0083] In some embodiments, the stirring cup 14 is provided with an inlet pipe 13 and a wastewater pipe 12 communicating with the stirring cup. Preferably, both the inlet pipe 13 and the wastewater pipe 12 extend to the bottom of the stirring cup.

[0084] In some embodiments, the stirring mechanism further includes: a reinforcing platform 25 extending axially along the transmission rod 172 at the point where the transmission rod 172 passes through the tube wall of the bent section 1602; a mounting groove for mounting the second sealing plug 173 is provided on one side of the reinforcing platform 25 connected to the bent section 1602. Specifically, the transmission rod 172 passes through the mounting groove of the reinforcing platform 25 and the second sealing plug 173 and extends to the discharge channel 22. See [reference needed]. Figure 8 .

[0085] In this embodiment, by providing the reinforcement platform 25, a thicker sealing plug can be installed (compared to the thickness of the sealing plug simply placed on the pipe wall), thereby improving sealing performance and equipment lifespan.

[0086] In some embodiments, an annular limiting sleeve is fixedly provided at one end of the transmission rod 172 near the actuating end 1701, thereby limiting the elastic reset member 21 through the mounting plane at the bottom of the reinforcing platform and the annular limiting sleeve, thus making it easier to install the elastic reset member and preventing the elastic member from swaying left and right. Furthermore, a limiting platform is provided inside the mounting box, which forms a guide channel extending along the axial direction of the transmission rod between the limiting platform and the dispensing section, and the size of the guide channel is adapted to the elastic reset member 21 and the annular limiting sleeve, thereby ensuring more stable transmission of the transmission rod.

[0087] In some embodiments, a shaft seal 23 is provided between the output shaft of the drive device and the bottom of the mounting housing 20 and the stirring cup 14. Specifically, the shaft seal is a mechanical seal composed of a moving ring and a stationary ring made of ceramic material.

[0088] In some embodiments, the operating lever 170 includes: a connecting portion 1703 rotatably mounted within the mounting housing 20; an actuating end 1701 for pushing the transmission rod 172 is provided on the bottom side of the connecting portion 1703 near the transmission rod 172; and an operating end 1702 extending out of the mounting housing 20 is provided on the top side of the connecting portion 1703 away from the transmission rod 172. Further, a handle is provided on the side of the operating end 1702 extending out of the mounting housing. Exemplarily, the top of the connecting portion 1703 is rotatably mounted within the mounting housing 20 via a pivot, which is analogous to the fulcrum of a seesaw. When a downward force is applied to the operating end 1702, the actuating end 1701 pushes the transmission rod 172 upward along its axial direction. See [reference needed]. Figure 8 .

[0089] Example 3: The stirring mechanism of the cocktail machine proposed in this embodiment has the same structure as the stirring mechanism in embodiment two. The difference is that the stirring mechanism in this embodiment also includes a recycling tank located below the second sealing plug 173. The bottom of the recycling tank is connected to a waste liquid discharge pipe.

[0090] Specifically, a groove communicating with the mounting groove can be provided below the mounting groove for installing the second sealing plug.

[0091] In this embodiment, long-term wear and tear has reduced the seal between the second sealing plug 173 and the transmission rod 172, resulting in a small amount of leakage. Of course, there may be other reasons for leakage, but the leakage will only accumulate in the recovery tank and will not affect other components inside the mounting box. Furthermore, a waste liquid discharge pipeline (running out of the mounting box) is provided, and a switch valve can be installed on this pipeline to discharge the waste liquid in the recovery tank.

[0092] Example 4: This application also provides another stirring mechanism, which differs from the stirring mechanism in Embodiment 3 above in that a liquid level sensor (which communicates with the control module) is installed on the wall of the recovery tank. This allows the wear degree of the second sealing plug to be assessed based on the liquid level data detected by the sensor and the time difference, thus enabling timely replacement of the second sealing plug. Specifically, The control module is configured to assess the wear degree of the second sealing plug based on the liquid level data detected by the liquid level sensor and the time difference, and to provide a prompt based on the wear degree.

[0093] In practical applications, since the first sealing plug 171 moves under the drive of the transmission rod 172 and there is long-term wear between it and the bottom of the stirring cup 14, and the second sealing plug 173 has long-term wear with the transmission rod 172, if there is a small amount of leakage between the first sealing plug 171 and the stirring cup 14 due to long-term wear, some liquid may flow through the pipe wall to the second sealing plug 173. Therefore, the degree of wear of the second sealing plug 173 is evaluated based on the liquid level data and time difference, which actually includes the degree of wear of the first sealing plug 171 and the second sealing plug 173 as a whole.

[0094] For example, in standby mode (when the liquid in the mixing cup 14 is not drained, such as prepared drinks or wastewater generated after cleaning), the control module records the time ΔT from the end of emptying the mixing cup 14 to the triggering of the liquid level sensor in the recovery tank (that is, when the hydraulic pressure in the recovery tank reaches the preset height, the liquid level sensor will send a trigger signal to the control module), and determines its magnitude compared with the predetermined time. If ΔT is greater than or equal to the predetermined time (i.e., the sensor is not triggered within the predetermined time), it is considered a normal leak. For example, micro-seepage in the pipeline: even with a good seal, a very small amount of liquid may enter the recovery tank due to process factors, but this amount of leakage will not affect the normal use of the cocktail machine.

[0095] If ΔT is less than the predetermined time (i.e., the sensor is triggered within the predetermined time), it is determined that the wear is too great and that leakage has occurred. During the dispensing or cleaning process, the control module records the time Δ from the start of dispensing or cleaning when the liquid level in the recovery tank rises from the initial level (which could be 0, or it could be when a small amount has accumulated) to the second height. 2; Calculate the dynamic leakage velocity V = ΔH / ΔH based on the time and the liquid level difference ΔH (i.e., the difference between the second height and the initial liquid level). 2:, If the flow rate V is greater than the first threshold, it indicates a serious leak and the sealing plug needs to be replaced. If the leakage is less than the first threshold but greater than the second threshold, it indicates a significant leak, requiring maintenance (e.g., disassembly and cleaning). If the leakage is less than the second threshold, it indicates normal wear and tear or normal leakage.

[0096] Example 5: like Figure 18 and Figure 21 As shown, this embodiment provides a cleaning system for a cocktail shaker, including: a cleaning liquid tank 28, a wastewater tank 27, cleaning pipelines and a control module, and at least one water supply component 302 for spraying cleaning liquid. The water supply component 302 is disposed above the capsule compartment 1 of the cocktail shaker. The cleaning pipeline includes: a first branch, a second branch (i.e., wastewater pipeline 45), a third water pump installed on the first branch, and a first water pump 26A installed on the second branch; the input end of the first branch is connected to the cleaning liquid tank 28 through an electronic valve assembly, and the first output end of the first branch is connected to the water supply component 302; the input end of the second branch is connected to the stirring cup 14 in the cocktail shaker, and the output end of the second branch is connected to the wastewater tank 27; the third water pump 26C, the electronic valve assembly, and the first water pump 26A are all electrically connected to the control module.

[0097] In some embodiments, the water supply component 302 is positioned above the capsule compartment 1 of the piercing device in the cocktail shaker, including positioning the water supply component 302 directly above or diagonally above the capsule compartment 1. It is sufficient that the water supply component 302 can provide cleaning fluid to the capsule compartment body in the capsule compartment 1 for cleaning. Preferably, the piercing device can be the piercing device described in the above embodiments.

[0098] Furthermore, in some embodiments, the control module is configured to activate a cleaning mode when the prepared beverage in the mixing cup 14 is emptied.

[0099] Specifically, users can manually trigger the cleaning mode, or a sensor (such as a liquid level sensor or an infrared sensor) can be installed in the mixing cup 14. Once the beverage in the mixing cup 14 is detected to be emptied, a corresponding trigger signal is sent to the control module to trigger the opening of the cleaning mode.

[0100] In some embodiments, the cleaning mode includes: the control module controlling the valve corresponding to the cleaning liquid tank 28 in the electronic valve assembly to open (if the valve is normally closed, the control module controls the valve corresponding to the cleaning liquid tank to switch from normally closed to open in the cleaning mode; if the valve is normally open, the control module keeps the valve open in the cleaning mode), and controlling the third water pump 26C to draw cleaning liquid (such as water) from the cleaning liquid tank 28, and supplying cleaning liquid to the capsule chamber 1 through the first branch, so that the cleaning liquid cleans the capsule chamber 1, and finally flows into the stirring cup 14 for cleaning; and After the stirring cup 14 has finished cleaning, the control module controls the first water pump 26A to draw cleaning liquid from the stirring cup 14 and discharge it to the wastewater tank 27 through the second branch.

[0101] In other embodiments, the cleaning mode includes: the control module controlling the valve in the electronic valve assembly corresponding to the cleaning liquid tank 28 to open, and controlling the third water pump 26C to draw cleaning liquid (such as water) from the cleaning liquid tank 28, and supplying the cleaning liquid to the capsule chamber 1 through the first branch, so that the cleaning liquid cleans the capsule chamber 1, and finally flows into the stirring cup 14 for cleaning; and After the capsule chamber 1 is cleaned, the control module controls the air valve 33 in the electronic valve assembly to open, allowing the cleaning gas, such as air, drawn by the third water pump 26C to draw the residual cleaning liquid in the first branch into the capsule chamber 1, and finally into the stirring cup 14; and After the stirring cup 14 has finished cleaning, the control module controls the first water pump 26A to draw cleaning liquid from the stirring cup 14 and discharge it to the wastewater tank 27 through the second branch.

[0102] This application provides a cleaning system that can be built into the base of a cocktail shaker, allowing users to automatically clean the inside of the shaker without disassembling any parts. Furthermore, since the piercing device and the stirring mechanism are connected and on the same cleaning path, there is no need to clean the piercing device and the stirring mechanism separately. Specifically, in the piercing device, the cleaning system injects clean water into the capsule compartment from a water supply component at the top of the capsule compartment via a cleaning pipeline, rinsing the inner wall of the capsule compartment and the piercing component. Further, because the capsule compartment is structurally connected to the stirring cup of the stirring mechanism, the water used to clean the capsule compartment immediately enters the stirring cup through the connection path, allowing the water used to clean the capsule compartment to directly clean the stirring cup. This not only saves energy but also simplifies the cleaning pipeline, eliminating the need for separate cleaning pipelines for the piercing device and the stirring mechanism. Therefore, through the design of the cleaning pipeline and the connection between the piercing device and the stirring mechanism, the core parts of the cocktail shaker that need cleaning—the capsule compartment and the stirring cup—can be covered simultaneously, achieving efficient and thorough integrated automatic cleaning.

[0103] In actual use, different ingredients, such as different base spirits, need to be injected into the mixing cup during a single mixing process. However, these ingredients share the same base spirit pipeline. Therefore, if there is residue in the pipeline, on the one hand, it will cause a deviation in the final proportion of each ingredient; on the other hand, the ingredients will pre-mix and react in the pipeline, thus affecting the taste. Therefore, in this embodiment, it is proposed to use a cleaning gas, such as air, to clean the pipeline during the mixing process, thereby avoiding premature mixing and reaction of different ingredients and preventing the amount of residue in the pipeline from affecting the proportion of each ingredient. Specifically, in some other embodiments, the control module is also configured to: open the air valve 33 according to the opening timing in the first preset timing control strategy / second preset timing control strategy during the beverage mixing process, thereby forming an air isolation column to clean the base spirit pipeline before the next ingredient, such as the next base spirit, enters the first branch.

[0104] The first preset timing control strategy includes: after the previous component, such as base liquor, is extracted, the air valve 33 is opened, and air is drawn out by the second water pump 26B to clean the main pipeline 44 and the base liquor pipeline; and when cleaning is completed, the second electronic valve 35 corresponding to the next component, such as base liquor, is opened to extract the next component, such as base liquor. In practical applications, if the properties of the components are significantly different, premature mixing of the two components in the pipeline will cause a rapid reaction (such as protein coagulation upon contact with acid, or carbonated beverages and spirits), which will greatly affect the taste. Since customers are very sensitive to the flavor of the alcoholic beverage, the first preset timing control strategy is preferred for scenarios where the properties of the components are significantly different and the flavor requirements are extremely high.

[0105] The second preset timing control strategy includes: after the previous component, such as base wine, is extracted, the air valve 33 is opened at time T1 to draw air through the second water pump 26B to clean the main pipeline 44 and the base wine pipeline; then, at time T2, the second electronic valve 35 corresponding to the next component, such as base wine, is opened, thereby achieving parallel extraction of the next component; where T2-T1=△t, and △t is the preset delay time. Setting this preset delay time ensures that the extraction of the next component, such as base wine, is carried out simultaneously before the previous component, such as base wine, is completely cleaned out of the pipeline (that is, compared with the first preset timing control strategy, the second preset timing control strategy is a parallel mechanism with a certain delay), which means that the speed of pouring is considered while taking into account the taste.

[0106] Furthermore, different preset delay times can be set based on the ease of cleaning of the ingredients in the formula (characterized by the viscosity or consistency of the ingredient). For example, a larger preset delay time can be set for ingredients with high viscosity / constancy (such as syrups), while an initial or default preset delay time can be used for ingredients with low viscosity / constancy (such as sake, which is easy to rinse). For instance, if the viscosity / constancy (which can be pre-stored in the formula) is greater than a preset viscosity threshold, the preset delay time is extended beyond the initial or default preset delay time.

[0107] In other embodiments, both of the above strategies can be implemented simultaneously, and the second preset timing control strategy is pre-configured as the default mode / initial mode. In actual use, the user can choose between the two strategies according to actual needs.

[0108] In some embodiments, a flow meter 30 is also provided on the first branch for detecting the flow rate of the cleaning liquid drawn by the third water pump 26C, or for detecting the flow rate of the component drawn by the second water pump 26B.

[0109] Of course, in other embodiments, the above-mentioned preset delay time may not be used. Instead, the detection result of the flow meter 30 can be used to control the opening time of the valve corresponding to the base wine. That is, in the second preset timing control strategy, when the residual liquid in the pipeline is driven through the flow meter 30 under the action of the cleaning gas, the flow meter 30 sends a trigger signal to the control module. The control module generates a corresponding control signal to control the opening of the valve corresponding to the base wine, and the base wine is extracted by the corresponding water pump, thereby realizing the parallel delivery of cleaning and base wine in the pipeline with delay.

[0110] In some embodiments, the cleaning system further includes: a third branch, wherein the first input end of the third branch is connected to the acid water tank 29 in the cocktail shaker, the second input end of the third branch is connected to the second output end of the first branch, the output end of the third branch is connected to the stirring cup 14, and a fourth water pump 26D is provided on the third branch; the fourth water pump 26D is electrically connected to the control module.

[0111] After the fourth water pump 26D draws acid water from the acid water tank 29, the control module controls the air valve 33 in the electronic valve assembly to open, allowing the drawn-in cleaning gas, such as air, to clean the residual acid water in the third branch. Specifically, the formula includes the extraction order of acid water and other components. Correspondingly, the control module opens the air valve 33 based on the opening timing in the first / second preset timing control strategy, thereby forming an air isolation column for cleaning after the acid water enters the mixing cup.

[0112] In some embodiments, at least one water supply component 302 is disposed on a cover plate above the capsule chamber 1, and the water supply component 302 is connected to the first output end of the first branch. Specifically, each water supply component 302 corresponds to one capsule chamber body in the capsule chamber 1.

[0113] In some embodiments, the electronic valve assembly includes: an air valve 33 communicating with the input of the first branch, and a first electronic valve 34 disposed between the input of the first branch and the cleaning fluid tank 28.

[0114] For example, the electronic valve assembly is connected to the piping system of the cocktail mixer. Specifically, the piping system includes a main pipeline 44, the output end of which is connected to the input end of a first branch pipeline. The main pipeline 44 includes a cleaning pipe section 44A and a base liquor pipe section 44B that are sequentially connected in a direction gradually approaching the first branch pipeline. Correspondingly, the air valve 33 in the electronic valve assembly is located at the air inlet of the cleaning pipe section 44A, and the first electronic valve 34 is located at the cleaning liquid inlet of the cleaning pipe section 44A.

[0115] Example 6: Based on the above-described cleaning system, this embodiment provides an automatic cleaning method for a cocktail shaker. The cocktail shaker includes: a puncture device (as described in the above embodiment), a stirring mechanism (as described in the above embodiment), a piping system, and a control module, as well as an electronic valve assembly electrically connected to the control module; and the cleaning system for the cocktail shaker described in the above embodiment (the control module in this cleaning system can be integrated with the control module of the cocktail shaker). Accordingly, the automatic cleaning method includes the following steps: S101, when the prepared liquid in the stirring mechanism is emptied, the first electronic valve 34 in the electronic valve assembly corresponding to the cleaning liquid tank 28 is opened.

[0116] In some embodiments, the user can manually trigger the control module to start the cleaning mode, for example, by using the cleaning mode switch button on the cocktail shaker.

[0117] In other embodiments, when a level sensor pre-installed in the stirring cup detects that the prepared liquid in the stirring cup has been emptied (for example, the level sensor detects that the level of the prepared liquid in the stirring cup has become 0, close to 0, or below a preset minimum level), the level sensor sends a corresponding electrical signal to the control module. The control module then determines whether the cover is closed based on the electrical signal fed back by the sensor on the top cover of the capsule chamber (such as a pressure sensor / infrared sensor used to detect whether the cover is closed). If the cover is closed (of course, the capsule in the capsule chamber has been removed at this time), the cleaning mode is activated, causing the first electronic valve 34 in the electronic valve assembly corresponding to the cleaning liquid tank to open.

[0118] Of course, if the user manually triggers the cleaning mode, it is also necessary to first determine whether the cover is closed. If it is closed, the cleaning mode will be started; if it is not closed, the user will be prompted to close the cover.

[0119] S102, control the third water pump 26C in the cleaning system to draw cleaning liquid from the cleaning liquid tank 28, so that the cleaning liquid enters the capsule chamber 1 in the puncture device through the cleaning system for automatic cleaning.

[0120] S103, when the cleaning liquid enters the stirring cup 14 through the puncture device, the driving device 19 in the stirring mechanism is controlled to drive the stirring blade 15 to stir and clean.

[0121] In some embodiments, during the cleaning mode, the control module determines whether the liquid level detected by the liquid level sensor in the stirring cup 14 is greater than a preset liquid level threshold. If so, it controls the drive device 19 to drive the stirring blade 15 to perform stirring and cleaning.

[0122] S104, when the stirring mechanism has completed cleaning, the first water pump 26A in the cleaning system is controlled to extract the cleaning liquid from the stirring cup 14 and discharge it into the wastewater tank 27.

[0123] In some embodiments, the cleaning time of the stirring mechanism can be preset. Once the preset cleaning time is reached, the control module controls the drive device 19 to stop working and simultaneously controls the first water pump 26A to extract the cleaning liquid from the stirring cup 14.

[0124] In practical applications, besides cleaning after each beverage preparation, it's also necessary to consider the impact of residues of different ingredients in the piping on the beverage's flavor during the mixing process. For example, residues in the piping can cause deviations in ingredient ratios, or residues from one ingredient in the piping may react with a previously mixed ingredient, affecting the flavor. Therefore, this embodiment proposes cleaning during the beverage preparation process, such as bartending. Specifically, multiple containers storing different ingredients can be placed around the bartender, connected to each container via piping, and each container's corresponding piping is equipped with a corresponding second electromagnetic gate 35. See, for an example... Figure 18 The bartending machine is surrounded by multiple component supply stations with storage tanks for providing different base spirits. These tanks are connected to the bartending machine via pipelines, and each storage tank is equipped with a corresponding second electronic valve 35 on its pipeline.

[0125] In some embodiments, the automatic cleaning method further includes the step of: During the beverage preparation process, after each ingredient, such as base spirit, is extracted, the corresponding second electronic valve 35 is closed, and the air valve 33 in the electronic valve assembly is opened. A second water pump 26B then draws in cleaning gas, such as air, to clean the base spirit supply lines in the cocktail mixer. Once cleaning is complete (e.g., draining residual liquid from the lines into a puncture device), the second electronic valve 35 corresponding to the next ingredient, such as base spirit, is opened to extract the next ingredient, such as base spirit. This employs the first preset timing control strategy described in the above embodiment.

[0126] In other embodiments, the automatic cleaning method further includes the step of: during the preparation of a beverage, such as in a cocktail preparation process, opening an air valve 33 according to the opening timing in a second preset timing control strategy, thereby forming an air isolation column to clean the base liquor pipeline supplying the base liquor before the next component, such as base liquor, enters the first branch.

[0127] The second preset timing control strategy includes: after each component, such as base wine, is extracted, the corresponding second electronic valve 35 is closed, and the air valve 33 in the electronic valve assembly is opened at a first moment T1. This allows the second water pump 26B to extract cleaning gas, such as air, to clean the base wine supply pipeline. Then, at a second moment T2, the second electronic valve 35 for the next component to be extracted, such as base wine, is opened. T2 - T1 = Δt, where Δt is a preset delay time. Compared to the first preset timing control strategy, the second preset timing control strategy is a parallel mechanism with a certain delay, essentially considering both taste and pouring speed.

[0128] Of course, in other embodiments, the aforementioned preset delay time Δt may not be used. Instead, the detection result of the flow meter 30 set in the first branch can be used to control the opening time of the valve corresponding to the base liquor. That is, in the second preset timing control strategy, when the residual liquid in the pipeline is driven through the flow meter 30 under the action of the cleaning gas, the flow meter 30 sends a trigger signal to the control module. The control module generates a corresponding control signal to control the opening of the valve corresponding to the base liquor and extracts the base liquor through the corresponding water pump, thereby realizing the delayed parallel delivery of the cleaning gas and the base liquor in the pipeline.

[0129] Furthermore, different preset delay times can be set based on the ease of cleaning of the ingredients in the formula (characterized by the viscosity or consistency of the ingredient). For example, a larger preset delay time can be set for ingredients with high viscosity / constancy (such as syrups), while an initial or default preset delay time can be used for ingredients with low viscosity / constancy (such as sake, which is easy to rinse). For instance, if the viscosity / constancy (which can be pre-stored in the formula) is greater than a preset viscosity threshold, the preset delay time is extended beyond the initial or default preset delay time.

[0130] In other embodiments, both of the above-mentioned preset timing control strategies can be simultaneously implemented, and the second preset timing control strategy is pre-configured as a default mode / initial mode. In actual use, the user can choose between the two strategies according to actual needs. Of course, the cocktail machine in this embodiment can also be the cocktail machine in Embodiment Seven below.

[0131] Example 7: like Figure 16 and Figure 17 As shown, this embodiment provides an automatically cleanable cocktail mixer, which includes: a piercing device 41, a stirring mechanism 42, a piping system, a cleaning system, and a control module, as well as an electronic valve assembly electrically connected to the control module; the stirring mechanism 42 is disposed above the dispensing station 43, and the piercing device 41 is located above the stirring mechanism 42 and communicates with the piercing device; wherein, The cleaning system includes: a cleaning solution tank 28 and a wastewater tank 27 (preferably, the cleaning solution tank 28 and the wastewater tank 27 are arranged side by side next to the wine dispensing station 43, such as...). Figures 20-22The cleaning pipeline includes a first branch, a second branch, a third water pump 26C installed on the first branch, and a first water pump 26A installed on the second branch. The input of the first branch is connected via the electronic valve assembly to the cleaning liquid tank 28, a container storing different ingredients for beverage preparation (such as multiple storage barrels storing different base spirits), and the outside atmosphere (or to a storage box storing cleaning gas). The first output of the first branch is connected to the capsule compartment 1 in the cocktail mixer. The input of the second branch is connected to the mixing cup 14 in the cocktail mixer, and the output of the second branch is connected to the wastewater tank 27. The third water pump 26C, the air valve 33 of the electronic valve assembly, and the first water pump 26A are all electrically connected to the control module. (See also...) Figure 14 .

[0132] The piping system includes a main pipeline 44 located above the cleaning liquid tank 28 and the wastewater tank 27, a fifth branch pipeline, and a second water pump 26B installed on the fifth branch pipeline. The main pipeline 44 has multiple input terminals connected to the electronic valve assembly, and the output terminal of the main pipeline 44 is connected to the input terminal of the first branch pipeline. The input terminal of the fifth branch pipeline is connected to the third output terminal of the first branch pipeline, and the output terminal of the fifth branch pipeline is connected to the stirring cup 14, thereby forming a base liquor pipeline 11A for supplying base liquor between a portion of the first branch pipeline and the fifth branch pipeline.

[0133] In some embodiments, the aforementioned cleaning lines are actually part of the cocktail machine piping system.

[0134] Different beverages require different ingredients. For example, some beverages require acidic water during preparation, while others do not. To further increase the diversity of beverage preparation, in some embodiments, the cocktail mixer, in addition to the aforementioned components, also includes an acidic water tank 29 located above the main pipeline 44. Correspondingly, the cleaning system also includes a third branch, the first input of which is connected to the acidic water tank 29 in the cocktail mixer, the second input of which is connected to the second output of the first branch, and the output of which is connected to the mixing cup 14. A fourth water pump 26D is installed on the third branch; the fourth water pump 26D is electrically connected to the control module. Correspondingly, the above-mentioned pipeline system also includes a fourth branch, the input of which is connected to the acidic water tank 29, and the output of which is connected to the first input of the third branch, thereby forming an acidic water pipeline 10 for supplying acidic water.

[0135] After the fourth water pump 26D draws acid water from the acid water tank 29, the control module controls the air valve 33 in the electronic valve assembly to clean the residual acid water in the third branch by drawing air.

[0136] In some embodiments, see Figure 18 A four-way connector 31B is installed in the first branch. The output end of the four-way connector 31B is connected to the input end of the third water pump 26C, the input end of the second water pump 26B, and the second input end of the three-way connector 31A (that is, the output end of the four-way connector connected to the second water pump serves as the third output end of the first branch, and the output end of the four-way connector connected to the three-way connector serves as the second output end of the first branch). The first input end of the three-way connector 31A is connected to the acid water tank 29, and the output end of the three-way connector 31A is connected to the input end of the fourth water pump 26D. In other words, the reuse of multiple pipelines is achieved through the connection of the three-way connector and the four-way connector, thereby greatly reducing the complexity of pipeline design.

[0137] Furthermore, in some embodiments, a pipeline level sensor 32 is provided on the fourth branch.

[0138] The cocktail mixer in this embodiment integrates three main functions: a piercing device, a stirring mechanism, and a cleaning system, with the cleaning system built into the base 39. Through the internal structural layout design, the traditionally bulky and disorganized cocktail mixer achieves a more compact and efficient space utilization. Furthermore, the entire cocktail mixer has no exposed redundant pipes or separate components, presenting a clean and integrated appearance.

[0139] The cocktail mixer in this embodiment features an integrated design that combines capsule puncturing, stirring, and cleaning functions. Thanks to its cleaning system, users can clean the internal tubing without disassembling any parts. This integrated design achieves miniaturization while freeing users from repetitive cocktail-making procedures, significantly improving the cocktail mixer's portability.

[0140] Preferably, the piercing device can be the piercing device in the above embodiments, and correspondingly, the stirring mechanism is the stirring mechanism in the above embodiments, with the piercing device positioned above the stirring mechanism. Specifically, see... Figure 1 and Figure 10 The piercing device has a fastening end 901 in the docking chamber 9, and the stirring cup 14 of the stirring mechanism has a buckle 902 that cooperates with the fastening end. The two fastening parts are also equipped with magnets 37 to ensure the stable installation of the piercing device and the stirring mechanism.

[0141] In some embodiments, the mixing cup is further provided with an electrode 38, such as a pin, that is electrically connected to the drive device of the stirring mechanism, see [link to relevant documentation]. Figure 14This allows the control circuit board (such as the control module) and the drive device to be set up separately (specifically, the drive device can be electrically connected to the control circuit board through the electrode), thereby making more space available in the mounting box 20.

[0142] like Figure 22 As shown, in some embodiments, the main pipeline 44 includes a cleaning pipe section 44A and a base liquor pipe section 44B sequentially connected in a direction gradually approaching the first branch pipeline (or stirring mechanism) (i.e., the base liquor pipe section 44B is closest to the stirring mechanism, while the cleaning pipe section 44A is farthest from the stirring mechanism). Accordingly, The electronic valve assembly includes: an air valve 33 disposed at the air inlet of the cleaning pipe section 44A, a first electronic valve 34 disposed at the cleaning liquid inlet of the cleaning pipe section 44A; and a plurality of second electronic valves 35 disposed at uniform intervals in the base wine pipe section 44B.

[0143] In some embodiments, a plurality of second electronic valves 35 are respectively disposed on both sides of the base liquor pipe section 44B; the air valve 33 and the first electronic valve 34 are respectively disposed on both sides of the cleaning pipe section 44A, see [reference]. Figure 18 , Figure 21 and Figure 22 .

[0144] In some embodiments, the electronic valve assembly further includes a third electronic valve 36 disposed on the fourth branch.

[0145] In some embodiments, the cocktail machine further includes a display module (not shown) electrically connected to the control module.

[0146] In other embodiments, the control module of the cocktail machine is configured to control the opening sequence of each valve in the electronic valve assembly based on a first preset timing control strategy / a second preset timing control strategy, so as to introduce an air column (formed by the extracted cleaning gas) between different components, such as base spirits, for isolation and cleaning. The first preset timing control strategy includes: when the previous component, such as base wine, is extracted, the air valve 33 is opened and the second water pump 26B is used to extract cleaning gas, such as air, to clean the base wine pipeline 11A; and when the cleaning is completed, the second electronic valve 35 corresponding to the next component, such as base wine, is opened to extract the next component, such as base wine. The second preset timing control strategy includes: when the previous component, such as base wine, is extracted, the air valve 33 is opened at time T1 to extract cleaning gas, such as air, through the second water pump 26B to clean the base wine pipeline 11A, and then the second electronic valve 35 corresponding to the next component, such as base wine, is opened at time T2, thereby realizing parallel extraction of base wine; where T2-T1=△t, and △t is the preset delay time.

[0147] Example 8: Based on the cocktail machine of the above embodiments, this application also provides a control method for the cocktail machine, which will be described in detail below with reference to specific embodiments.

[0148] In some embodiments, the control method includes the steps of: S11, Obtain a cocktail recipe; the cocktail recipe includes: at least one base spirit, and the extraction order of multiple base spirits and the extraction amount of each base spirit.

[0149] In some embodiments, the required ingredients vary depending on the beverage the user wants to prepare, and the extraction order and amount of each ingredient are recorded in the pre-stored recipes. Specifically, the user can automatically select various pre-stored cocktail recipes through an input module or human-computer interaction module such as a display module or keyboard, and insert capsules of the corresponding flavor into the puncture device.

[0150] In other embodiments, if the beverage prepared by the user also requires acidic water as an ingredient, the cocktail recipe will also include the required amount of acidic water extracted.

[0151] S12, according to the extraction sequence, control the opening of each valve in the electronic valve assembly, and control the second water pump to extract the corresponding amount of base wine according to the extraction amount of each type of base wine.

[0152] In this process, after each component, such as base wine, is extracted, the corresponding second electronic valve is closed. Based on the pre-stored first preset timing control strategy / second preset timing control strategy, the opening sequence of each valve in the electronic valve assembly is controlled to introduce an air column for isolation and cleaning between the extraction of different components, such as different base wines. The first preset timing control strategy includes: when the previous component, such as base wine, is extracted, the air valve 33 is opened and the second water pump 26B is used to extract air to clean the base wine pipeline 11A; and when the cleaning is completed, the second electronic valve 35 corresponding to the next component, such as base wine, is opened to extract the next component, such as base wine. The second preset timing control strategy includes: when the previous component, such as base wine, is extracted, the air valve 33 is opened at time T1 to extract air through the second water pump 26B to clean the base wine pipeline 11A, and then the second electronic valve 35 corresponding to the next component, such as base wine, is opened at time T2, so as to achieve parallel extraction of the next component, such as base wine; where T2-T1=△t, and △t is the preset delay time.

[0153] For example: Since the distance between air valve 33 and the outlet of main pipeline 44 is ΔL, and the distances between each base liquor inlet upstream of it and the outlet of main pipeline 44 are all less than ΔL; therefore, once air valve 33 is opened first, the time for the air column to enter the first branch is: t1 + ΔL / V; t1 is the moment when air valve 33 is opened; therefore, the time for the next base liquor to enter the first branch is t2 ≥ t1 + ΔL / V, that is, after the air enters the first branch but before it is discharged from the pipeline, the next base liquor is extracted, so that the base liquor and the air column can be transported in the pipeline simultaneously. Here, V is the speed at which the corresponding air pump extracts clean gas, such as air, that is, the transport speed of the air column in the pipeline.

[0154] S15, control the stirring mechanism to start stirring, and after the prepared beverage is discharged, control the first electronic valve to open, and control the third water pump to draw cleaning liquid from the cleaning liquid tank (such as the clean water tank) to clean the capsule chamber and puncture parts.

[0155] In some embodiments, the empty capsule is typically removed during the mixing process. Therefore, once the prepared beverage in the mixing cup is emptied, the user can manually trigger the cleaning mode. Alternatively, a sensor, such as a liquid level sensor or an infrared sensor, can be installed inside the mixing cup. Once the system detects that the beverage in the mixing cup has been emptied (emptying includes both completely emptying the mixing cup and leaving only a small amount of liquid, such as below a preset residual amount), a trigger signal is sent to the control module. The control module then automatically activates the cleaning mode (i.e., controls the third water pump 26C to extract cleaning liquid for pipeline cleaning).

[0156] Of course, in other embodiments, in this cleaning mode, the control module can also control the opening of the four-way connector 31B and the three-way connector 31A set on the first branch, so that the cleaning liquid can be used to clean the first branch while cleaning the fifth branch and the third branch, etc.

[0157] S16, control the stirring mechanism to start stirring for cleaning, and when cleaning is completed, control the first water pump to discharge the cleaning liquid in the stirring mechanism.

[0158] In other embodiments, if acidic water is required during the preparation process, the following steps are included before performing step S15: S13, control the fourth water pump 26D to extract the corresponding amount of acid water according to the amount of acid water extracted.

[0159] S14, after the corresponding acid water is extracted, the air valve 33 in the electronic valve assembly is opened, and the fourth water pump 26D extracts air to clean the residual acid water in the third branch.

[0160] In some embodiments, the formulation includes the timing of acid water extraction and its extraction order with other components. Accordingly, the control module opens the air valve 33 and the fourth water pump 26D based on the opening timing in the first preset timing control strategy / second preset timing control strategy, thereby forming an air isolation column for cleaning after the acid water enters the third branch, thereby preventing some acid water from remaining in the pipeline and reducing the amount of acid water participating in the mixing process.

[0161] In some embodiments, the control method further includes the step of: S17, Obtain the viscosity value of the previous extracted component, such as the base spirit, from the obtained cocktail recipe.

[0162] In some embodiments, the cocktail recipe may specify the name and amount of each ingredient, and may also specify the viscosity value of each ingredient, such as the base spirit.

[0163] S18, determine whether the viscosity value of the previous extracted component is greater than or equal to a preset viscosity threshold. If so, execute the first preset timing control strategy to control the opening of the valve, that is, first use cleaning gas to clean the residual components in the pipeline, and then extract the next component, such as base wine. If the viscosity value of the previous component is less than the preset viscosity threshold, execute the air and the next base wine parallel push strategy, such as the second preset timing control strategy, that is, first open the air valve, and after a preset delay time, open the next component, such as the valve corresponding to the base wine and the second water pump 26B.

[0164] In some embodiments, the control method further includes the step of: if the viscosity value of the previous component is greater than the preset viscosity threshold, dynamically updating the above delay time based on the viscosity value: Δt = (1 + K) * Δt, K = (viscosity value - preset viscosity threshold) / preset viscosity threshold.

[0165] In the beverage preparation process of this application, the amount of each ingredient, such as base spirit and acidic water, is fixed. If the amount of any ingredient is insufficient, the final beverage, such as alcohol, may taste different from the desired flavor. Therefore, to avoid insufficient amounts of each ingredient, such as base spirit or acidic water, entering the mixing cup due to residue in the pipes during the preparation process, resulting in a lack of final flavor, this application proposes a control method for a cocktail mixer. This method involves immediately cleaning the pipes with air after each ingredient, such as base spirit, to reduce the amount of residue in the pipes.

[0166] Furthermore, based on the viscosity value of the previous component, such as the base wine, an appropriate timing control strategy is selected to control the timing of the start-up between air extraction and the extraction of the next component. This allows an air column to be formed before the extraction of the next component, so that the next component and the air column are simultaneously processed in the pipeline. This ensures that the residual amount is cleaned at the same time, while preventing the premixing of different components, such as different base wines.
