DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0036] In the related art, a capsule coffee machine is a device for automatically brewing espresso, and its main working process is as follows: first, the user puts the capsule into the extraction chamber of the coffee machine, punctures the capsule with an extraction needle located in the brewing chamber, and then the coffee machine delivers hot water into its extraction chamber, so that the hot water enters the capsule and mixes with the espresso, until all the espresso in the capsule is extracted, and the extracted coffee beverage is obtained and flows out through the liquid outlet of the coffee machine. In the prior art, when the espresso in the capsule is extracted by a capsule coffee machine, usually only a single capsule can be extracted. On the one hand, when the user has a high demand for the cup volume and concentration of the coffee beverage, the existing capsule coffee machine is limited by the boiler pressure and the size of the capsule, and can only complete a single extraction at a time. When the concentration reaches the standard, the amount of coffee liquid in the coffee beverage obtained is low, it is difficult to control the quality of the coffee, and the taste of the coffee beverage is affected. It is difficult to meet the high demand of users in a short time; on the other hand, since the existing capsule coffee machine can only extract a single coffee capsule, it is not convenient to mix different flavors and it is difficult to meet the different needs of users.

[0037] In view of this, the present application provides a brewing system, comprising at least two extraction structures 1, at least two extraction structures 1 are connected to a liquid outlet component 2, wherein any extraction structure 1 comprises an extraction unit 110 and a switching component 120, an extraction chamber is provided in the extraction unit 110, the extraction chamber is connected to the liquid outlet component 2, and is used to extract the espresso in the capsule in the extraction chamber; the switching component 120 is connected to the extraction chamber, and is used to regulate the on-off state of water entering the extraction chamber.

[0038] Specifically, see Figure 1 and Figure 2The brewing system provided by the present application includes at least two extraction structures 1, each of which includes an extraction unit 110, and each of which can extract the concentrated coffee in the capsule in its extraction chamber. Therefore, by applying at least two extraction structures 1 in the brewing system, it is possible to achieve concurrent extraction of multiple capsules and increase the extraction dosage of the capsule by the brewing system; when the user has a high demand for coffee drinks, the at least two extraction structures 1 in the brewing system can be made to work simultaneously to increase the amount of coffee drinks obtained, avoid the problem of low coffee liquid volume in the drink due to insufficient extraction dosage of concentrated coffee, and ensure the quality of the coffee. The coffee beverages are discharged from the plurality of extraction structures 1 in a container.

[0039] Illustratively, the brewing structure provided by the present application can meet different needs of users. When a user serves multiple cups of coffee drinks, at least two extraction structures 1 in the brewing system can work in turn, thereby ensuring the quality of the coffee drinks while improving the extraction efficiency of the coffee; or, when a user needs to serve a large amount of coffee drinks at one time, that is, when the demand for coffee drinks is high, at least two extraction structures 1 in the brewing system can be used to extract the espresso in the capsules in their respective extraction chambers at the same time, and the espresso can flow out through the common liquid outlet part 2, thereby increasing the amount of coffee drinks obtained to meet the actual needs of the user.

[0040] It should be noted that at least two extraction structures 1 in the aforementioned brewing system are connected through a liquid outlet component 2, so the liquid outlet component 2 can be configured as a liquid outlet pipe with multiple inlet ends, so that multiple extraction structures 1 share one liquid outlet pipe to discharge the extracted coffee beverage; or, the liquid outlet component 2 can use a liquid outlet pipe group arranged closely, so that the user can simultaneously receive the coffee beverage discharged by at least two extraction structures 1, thereby reducing interference between the extraction structures 1; in addition, the aforementioned switching component 120 is used to regulate the on-off state of the water entering the extraction chamber, so the switching component 120 can use an electric valve body structure such as a solenoid valve, so as to control the water entering the extraction chamber to extract the espresso in the capsule.

[0041] With respect to the brewing system provided in the present application, by adopting at least two extraction structures 1 in the brewing system, multiple capsules can be extracted at the same time, which can not only increase the amount of coffee beverage obtained, but also ensure the amount of coffee liquid in the beverage, thereby guaranteeing the taste and quality of the coffee beverage; and at least two extraction structures 1 share a liquid outlet component 2, which can prepare and mix coffee of different flavors to meet the different needs of users.

[0042] In some embodiments, the brewing system also includes a control unit, which is electrically connected to the extraction unit 110 and is used to control the espresso in the capsule in the extraction chamber of at least one extraction unit 110; the control unit is electrically connected to the switching component 120 and is used to control the on-off state of the water flowing through the switching component 120.

[0043] Specifically, see Figure 1 and Figure 2 , the control unit in the brewing system can be electrically connected to the control unit in each extraction structure 1 and the switching component 120, respectively, to control the working state of the corresponding extraction structure 1; exemplarily, when the user needs to obtain a small cup of coffee drink, that is, when the demand for coffee drink is low, one of the extraction structures 1 can be controlled by the control unit to operate, so that the switching component 120 of one of the extraction structures 1 is opened, at this time, the hot water in the brewing system can flow into the extraction chamber through the switching component 120, and the extraction unit 110 is controlled to extract the espresso in the capsule in its extraction chamber; exemplarily, when the user needs to obtain a large cup of coffee drink, that is, when the demand for coffee drink is high, the control unit is used to control at least two extraction structures 1 in the brewing system to operate, and the switching components 120 in at least two extraction structures 1 are controlled to be opened respectively, so that the hot water in the brewing system flows into the corresponding extraction chamber through the switching components 120 in each extraction structure 1, and the at least two extraction units 110 are controlled to extract the espresso in the capsules therein, respectively, so as to meet the different needs of users for coffee drinks.

[0044] In some embodiments, the brewing system further comprises a heating unit 3, wherein a heating chamber is provided in the heating unit 3 and is respectively connected to the extraction chamber and the exchange component 120, for heating the water entering the heating chamber and pressurizing the heated water in the heating chamber.

[0045] Specifically, see Figure 1 and Figure 2When the extraction structure 1 extracts the espresso in the capsule, the heating unit 3 heats the water in its heating chamber to provide the extraction unit 110 with hot water for extracting the espresso; wherein, the water can enter the heating chamber of the heating unit 3 through the pipeline, and the heating unit 3 actively heats the water to quickly increase the water temperature, thereby obtaining hot water for extracting the espresso in the heating chamber; the water will generate water vapor in the heating chamber during the heating process to increase the pressure in the heating chamber, thereby forming hot water with high pressure in the heating chamber, the exchange component 120 is opened, and the high-pressure environment in the heating chamber presses the hot water out of the heating chamber and enters the extraction chamber of the extraction unit 110 through the exchange component 120, and the espresso in the capsule is extracted by the hot water.

[0046] It should be noted that the heating unit 3 in the brewing system can adopt an instant boiler. By utilizing the instant boiler, the water entering the heating chamber can be quickly heated, thereby shortening the heating time of the water, and thus improving the coffee extraction efficiency of the brewing system; wherein, the type, specification and application size of the boiler can be selected according to actual application requirements, and will not be elaborated here.

[0047] In some embodiments, the brewing system includes a water tank 4 , which is connected to the heating chamber of the heating unit 3 and is used to supply water to the extraction structure 1 , and the water tank 4 is connected to the exchange component 120 through a return pipe 410 .

[0048] Specifically, see Figure 1 and Figure 2 In the brewing system, water can be stored in the water tank 4 so that the heating unit 3 can continuously provide the extraction structure 1 with hot water for extraction; wherein the water tank 4 and the exchange component 120 in the extraction structure 1 can be connected through a return pipe 410. When the heating unit 3 provides excess hot water for the extraction unit 110, the excess hot water can flow back into the water tank 4 through the return pipe 410 used to connect the exchange component 120 and the water tank 4, so as to realize the reuse of water.

[0049] In some embodiments, the brewing system includes a pump body 5 and a flow meter 6 which are connected to each other; one of the pump body 5 and the flow meter 6 is connected to the water tank 4, and the other is connected to the heating chamber.

[0050] Specifically, see Figure 1 and Figure 2The brewing system may include a pump body 5 and a flow meter 6, wherein the pump body 5 can transport water from the water tank 4 to the heating unit 3, thereby providing the heating unit 3 with water to be heated; and the brewing system also includes a flow meter 6, which can measure the water flow rate transported by the pump body 5 and obtain the water flow rate information transported by the pump body 5 to the heating unit 3, to ensure that the hot water in the heating unit 3 can meet the extraction requirements of coffee; wherein the pump body 5 of the brewing system can adopt an electromagnetic pump with a pressurizing function, which can transport water to the heating unit 3 while further pressurizing the water in the heating chamber to increase the pressure in the heating chamber, and ensure the transportation effect of hot water from the heating chamber to the extraction chamber; the flow meter 6 can adopt a Hall flow meter with high sensitivity and accuracy to improve the measurement accuracy of the water flow.

[0051] It should be noted that the brewing system provided in the present application includes at least two extraction structures 1, and each extraction structure 1 may correspond to a heating unit 3, a pump body 5 and / or a flow meter 6; for example, Figure 1 As shown, for any extraction structure 1, it can be connected with the heating unit 3, the pump body 5 and the flow meter 6 in sequence through a pipeline to form an extraction line, so that each extraction structure 1 has good independence. When one of the extraction lines fails, it will not affect the normal use of other extraction lines; for example, Figure 2 As shown, at least two extraction structures 1 can be connected in sequence with the same heating unit 3, pump body 5 and flow meter 6 through pipelines, that is, at least two extraction structures 1 can share a heating unit 3, pump body 5 and flow meter 6, reducing the manufacturing cost of the entire brewing system.

[0052] Based on the same inventive concept, the present application also provides a control method applicable to the brewing system of any of the above embodiments, wherein the control method includes:

[0053] Step S100, receiving a user's coffee demand instruction;

[0054] In this step, the user sends a coffee demand instruction to the brewing system according to actual demand, and the brewing system receives the coffee demand instruction. The brewing system controls the brewing system to extract the espresso in the capsule according to the received coffee demand instruction.

[0055] Step S200, in response to the coffee demand instruction being the first preset instruction, controlling the switching component 120 of an extraction structure 1 to be turned on so that water flows into the extraction chamber of the extraction unit 110 through the switching component 120; controlling the extraction unit 110 to extract the concentrated coffee in the capsule in the extraction chamber so that the extracted coffee flows out through the liquid outlet component 2;

[0056] In this step, if the brewing system receives a first preset instruction for the coffee demand, the first preset instruction may include a first demand instruction for coffee by the user, for example, the first demand instruction may specifically be that the user needs a small cup of coffee drink; after receiving the first preset instruction, the brewing system controls one of the extraction structures 1 to operate, and turns on the switching component 120 of the extraction structure 1, so that the hot water for extraction flows into the extraction chamber of the extraction unit 110 in the extraction structure 1 through the switching component 120, and the espresso in the capsule is extracted by using the extraction unit 110 and the hot water entering the extraction chamber. After the espresso is extracted, a coffee drink is formed, which flows out through the liquid outlet channel of the brewing system, so that the user obtains the coffee drink with the demand corresponding to the first preset instruction.

[0057] Step S300, in response to the coffee demand instruction being the second preset instruction, controlling the switching components 120 of at least two extraction structures 1 to be turned on, so that water flows into the extraction chamber of the corresponding extraction unit 110 through the switching component 120; controlling at least two extraction units 110 to respectively extract the espresso in the capsule in their respective extraction chambers, so that the extracted coffee flows out through the liquid outlet component 2.

[0058] In this step, if the coffee demand received by the brewing system is a second preset instruction, the second preset instruction may include a second demand instruction for coffee by the user, for example, the coffee demand instruction may specifically be that the user needs a large cup of coffee beverage, and the capacity of the large cup is greater than the capacity of the small cup in the aforementioned step S20; when the brewing system receives the second preset instruction, it controls at least two extraction structures 1 to operate, and makes the switching components 120 in the at least two extraction structures 1 respectively conductive, so that the hot water for extraction flows into the extraction chamber of the corresponding extraction unit 110 through the switching component 120, controls at least two extraction units 110 and the hot water in their respective extraction chambers to extract the espresso in the capsule, so as to extract the espresso into a coffee beverage, and at least two extraction units 110 make the extracted coffee beverage flow out through the same liquid outlet channel, so that the user obtains the coffee beverage with the demand corresponding to the second preset instruction.

[0059] Specifically, see Figure 3, for the control method of the brewing system provided by the present application, the controller can be used as the executive body of the brewing system to receive the user's coffee demand instruction and also to control the working status of at least two extraction structures 1; when obtaining a coffee drink, the user sends a coffee demand instruction to the brewing system according to actual demand, and the controller receives the coffee demand instruction. After receiving the coffee demand instruction, the controller controls the brewing system to extract the espresso in the capsule according to the coffee demand instruction; wherein, if the coffee demand instruction received by the controller is the first preset instruction, the controller controls one of the extraction structures 1 to operate and turns on the switching component 120 of the extraction structure 1, so that the hot water for extraction flows into the extraction chamber of the extraction unit 110 of the extraction structure 1 through the switching component 120, and uses the extraction unit 110 and the extraction chamber to extract the espresso. The hot water is used to extract the espresso in the capsule to extract the espresso into a coffee beverage, and the espresso flows out through the liquid outlet channel of the brewing system, so as to obtain a coffee beverage with a demand amount corresponding to the first preset instruction; if the brewing system receives a second preset instruction for the coffee demand, the controller controls at least two extraction structures 1 in the brewing system to operate, and respectively connects the switching components 120 in the at least two extraction structures 1, so that the hot water for extraction flows into the extraction chamber of the corresponding extraction unit 110 through the switching component 120, controls at least two extraction units 110 and the hot water in their respective extraction chambers to extract the espresso in the capsule, so that the espresso forms a coffee beverage, and at least two extraction units 110 let the extracted coffee beverage flow out through the same liquid outlet channel, so that the user can obtain the coffee beverage with a demand amount corresponding to the second preset instruction.

[0060] Based on the same inventive concept, the present application also provides a coffee machine, comprising a brewing system as in any of the above embodiments, and a capsule replenishing structure for providing capsules to the brewing system.

[0061] Specifically, see Figure 4 By applying the brewing system in the aforementioned embodiment in the coffee machine, at least two extraction structures 1 can be selected according to the actual needs of the user to extract the concentrated coffee in the capsule, and the coffee beverage formed after the extraction can be discharged through the same liquid outlet component 2 to obtain a larger amount of coffee beverage. At the same time, the taste of the obtained coffee beverage will not be affected by the low amount of coffee liquid, thereby ensuring the quality of the coffee beverage. In addition, the present application also provides a capsule replenishment structure, which can be used to replenish capsules for the extraction unit 110 in the brewing system in time, thereby improving the automation level of the coffee machine and reducing labor input.

[0062] In some embodiments, the capsule replenishment structure includes a dispensing unit 7 and a feeding unit 8. The dispensing unit 7 is connected to the extraction chamber of the extraction unit 110 and is used to distribute the capsules entering the dispensing unit 7 to the extraction unit 110; the feeding unit 8 is connected to the dispensing unit 7 and is used to provide the dispensing unit 7 with capsules to be dispensed.

[0063] Specifically, see Figure 4-Figure 16 , using the capsule replenishing structure, capsules can be automatically replenished for at least two extraction structures 1 in the brewing system of the coffee machine; wherein, the feeding unit 8 in the capsule replenishing structure can store capsules and can continuously provide capsules to be distributed to the dispensing unit 7 connected thereto; after receiving the capsules provided by the feeding unit 8, the dispensing unit 7 can distribute the received capsules to at least two extraction structures 1, thereby realizing automatic filling and distribution of capsules.

[0064] In some embodiments, the distribution unit 7 includes a distribution box 710, a distribution tray 720 and a first driving member 730, wherein the distribution box 710 is provided with a distribution bin 7121 and a discharge channel 7122 that are interconnected, the distribution bin 7121 is connected to the feeding unit 8, and the discharge channel 7122 is connected to the extraction chamber of the extraction unit 110; the distribution tray 720 is rotatably arranged in the distribution bin 7121 to prevent the capsule from escaping from the feeding unit 8, and the edge area of ​​the distribution tray 720 is provided with a accommodating cavity 721 for transporting capsules, and the shape of the accommodating cavity 721 is adapted to the capsule; the output shaft of the first driving member 730 is transmission-connected to the distribution tray 720 to drive the distribution tray 720 to transport the capsule.

[0065] Specifically, see Figure 5-Figure 7After receiving the capsules provided by the feeding unit 8, the dispensing unit 7 will automatically distribute the capsules entering the dispensing unit 7; wherein the dispensing box 710 can be composed of a box body 712 and a box cover 711 with compatible structures, wherein the box body 712 of the dispensing box 710 is provided with a dispensing bin 7121 and a discharging channel 7122 that are interconnected, and at least two discharging channels 7122 can be provided, and each discharging channel 7122 can be arranged tilted, and the dispensing disk 720 can be rotatably arranged in the dispensing box 710, so that when the capsules provided by the feeding unit 8 enter the dispensing box 710 from the feeding unit 8, they can fall into the accommodating cavity 721 arranged on the dispensing disk 720, and the control The operation of the first driving member 730 can drive the distributing plate 720 connected to its output shaft to rotate synchronously, so that the distributing plate 720 can transfer the capsules located in the accommodating chamber 721. When the capsule moves to the feed port position area of ​​the discharge channel 7122, since the accommodating chamber 721 is in an inclined state, the capsule can slide out of the accommodating chamber 721 opened on the distributing plate 720 and enter the discharge channel 7122, and can enter the extraction unit 110 of the brewing system through the discharge channel 7122, thereby realizing automatic distribution of the capsule. After the capsule distribution is completed, the first driving member 730 drives the distributing plate 720 to rotate in the opposite direction, so that the distributing plate 720 returns to its original position and prepares for the next distribution of the capsule.

[0066] Please note that Figure 7 The distributing disc 720 can be set in a disc shape, and the accommodating cavity 721 can be set in a structure compatible with the capsule and arranged in the edge area of ​​the distributing disc 720. When the distributing disc 720 distributes capsules to the discharging channel 7122, the first driving member 730 drives the distributing disc 720 to rotate, so that the area of ​​the edge of the distributing disc 720 without the accommodating cavity 721 can be rotated to the bottom of the discharging port of the feeding unit 8, and the distributing disc 720 in this state blocks the capsules in the feeding unit 8 from falling; in addition, the first driving member 730 and the distributing disc 720 can be connected through a reduction gear set, so that the first driving member 730 can drive the distributing disc 720 to rotate stably; the box body 712 is equipped with a cover body 750 for protecting the reduction gear set so that the reduction gear set has a better working environment; in addition, the first driving member 730 can be set as a motor, and its specific model and specifications can be selected according to actual needs, which will not be repeated here.

[0067] Exemplarily, two discharge channels 7122 may be relatively arranged in the box body 712 of the dispensing box 710. For the convenience of distinction, the two storage channels may be the discharge channel 7122 on the first side and the discharge channel 7122 on the second side. When dispensing capsules to the discharge channel 7122 on the first side, the first driving member 730 is controlled to drive the dispensing plate 720 to rotate in the direction of the discharge channel 7122 on the first side, so that the dispensing plate 720 can release the capsules inside it into the discharge channel 7122 on the first side through the accommodating cavity 721; conversely, when dispensing capsules to the discharge channel 7122 on the second side, the first driving member 730 may be controlled to drive the dispensing plate 720 to rotate in the direction of the discharge channel 7122 on the second side, so that the dispensing plate 720 can release the capsules inside it into the discharge channel 7122 on the second side through the accommodating cavity 721, so as to distribute capsules to different discharge channels 7122.

[0068] In some embodiments, the dispensing unit 7 further includes a first identification plate 741 and a first sensor 742 . The first identification plate is fixedly connected to the output shaft of the first driving member 730 . The first sensor 742 is disposed on the dispensing box 710 for detecting the first identification plate 741 .

[0069] Specifically, see Figure 5 The distribution unit 7 using the capsule replenishment structure can automatically distribute capsules to at least two extraction structures 1; wherein the distribution unit 7 may include a first identification plate 741 and a first sensor 742, and the first sensor 742 is used to detect the position of the first identification plate 741 to determine the distribution status of the capsules by the distribution tray 720. Exemplarily, during the capsule distribution process, the first driving member 730 drives the distribution plate 720 to rotate so as to deliver the capsule in the accommodating cavity 721 into the discharge channel 7122 through the distribution plate 720. At the same time, the first sensor 742 can monitor the position of the first identification plate 741. When the first driving member 730 drives the distribution plate 720 to rotate, the first identification plate 741 fixedly connected to the output shaft of the first driving member 730 will also rotate synchronously, so that the first identification plate 741 moves out of the identification range of the first sensor 742. When the capsule is distributed, the first driving member 730 drives the distribution plate 720 and the first identification plate 741 to rotate in the opposite direction, so that the distribution plate 720 and the first identification plate 741 return to their original positions. At this time, the first sensor 742 re-identifies the first identification plate 741, thereby determining that the aforementioned capsule has completed the distribution process. It should be noted that the first sensor 742 may be a sensor with a detection function such as an infrared sensor. The first sensor 742 may detect whether the first identification plate 741 returns to its original position to determine whether the capsule dispensing process is completed.

[0071] Specifically, see Figure 8-Figure 16 The feeding unit 8 stores the capsules to be dispensed and can replenish the capsules for the dispensing unit 7, so that the dispensing unit 7 can continuously and automatically dispense capsules for at least two extraction structures 1; wherein the feeding unit 8 may include a base 810 connected to the dispensing unit 7 to provide a mounting position for the rotating seat 820, and the base 810 is provided with a release port corresponding to the feed port of the dispensing unit 7, and each release port is connected to one end of a bin body 830, and any bin body 830 is connected to the rotating seat 820, so that the capsules provided in the bin body 830 can pass through the release port and the discharge port Enter into the dispensing unit 7; there can be multiple bins 830 that can store coffee capsules of different flavors, thereby increasing the storage capacity of capsules and the diversity of their flavors; and the multiple bins 830 are evenly arranged along the edge area of ​​the rotating seat 820, and when one of the bins 830 rotates to a position corresponding to the discharge port of the base 810, the bin 830 releases capsules into the dispensing unit 7 through the release port and the discharge port; if other bins 830 are needed to replenish capsules, the second driving member 840 can drive the rotating seat 820 to rotate on the base 810 to achieve switching of different bins 830.

[0072] It should be noted that the rotating seat 820 and the base 810 can be connected by a rotating shaft and a bearing 821, so as to improve the smoothness of the rotation of the rotating seat 820 on the base 810 and reduce the wear between the rotating seat 820 and the base 810 during rotation; the sealing portion 831 can adopt a packaging film that is convenient for packaging the warehouse body 830, or it can adopt a detachable cover structure, both of which can seal the end of the warehouse body 830 away from the base 810; in addition, the second driving member 840 can be set as a motor, and its specific model and specifications can be selected according to actual needs, which will not be repeated here.

[0073] In addition, in order to ensure that each bin 830 can continuously provide capsules to the dispensing unit 7, multiple capsules can be arranged linearly along the length direction of the bin 830, so that the bin 830 can release the capsules therein one by one; wherein, the capsules placed inside the bin 830 can be capsules of different shapes such as cup-shaped, block-shaped, and disc-shaped, and the cross-sectional shape of the bin 830 perpendicular to its length direction is adapted to the shape of the internal capsules to prevent the capsules from moving around in the bin 830; for example, Fig.18 As shown, the capsule located inside the bin body 830 may be a cup-shaped coffee capsule composed of a sealing film layer and a cup body, and the shape of the capsule is the same as the cross-sectional shape of the bin body 830 , ensuring that the bin body 830 can stably deliver the capsule to the dispensing unit 7 .

[0074] In some embodiments, the warehouse body 830 is fixedly connected to the rotating seat 820 , an end of the warehouse body 830 close to the base 810 is set as an open end, and an end of the warehouse body 830 away from the base 810 is connected to a blocking portion 831 .

[0075] Specifically, see Figure 8-Figure 11 The bin body 830 is fixedly connected to the rotating seat 820 to hold the capsules to be distributed; wherein, when distributing the bin body 830, the first driving member 730 will drive the rotating seat 820 to rotate on the fixed seat, and when a bin body 830 fixedly arranged on the rotating seat 820 moves to a position corresponding to the discharge port of the base 810, that is, the release port corresponds to the discharge port, since the end of the bin body 830 close to the base 810 is an open end, the capsules in the bin body 830 will enter the dispensing unit 7 through the release port, and then the capsules will be distributed using the dispensing unit 7; in addition, a blocking portion 831 is connected to the end of the bin body 830 away from the base 810, and the blocking portion 831 can be a cover body or a blocking film layer. When it is necessary to replenish capsules, the blocking portion 831 can be removed so as to fill capsules into the bin body 830.

[0076] In some embodiments, a chuck 834 is provided above the rotating seat 820, and a chuck hole 835 is provided along the edge of the chuck 834. The chuck 834 is sleeved on the warehouse body 830 through the chuck hole 835 to limit the warehouse body 830, and the chuck 834 is connected to the rotating seat 820 through a connecting column 836.

[0077] Specifically, see Figure 8 and Fig. 9By applying the chuck 834 in the distribution unit 7, the warehouse body 830 arranged on the rotating seat 820 can be fixed and limited; wherein, the edge area of ​​the chuck 834 can be evenly provided with a chuck hole 835 adapted to the warehouse body 830, and each warehouse body 830 is respectively penetrated in the chuck hole 835, thereby improving the tightness between the multiple warehouse bodies 830; one or more connecting columns 836 can be provided to connect the chuck 834 and the rotating seat 820, and at the same time, it also plays a certain supporting role on the chuck 834, preventing the chuck 834 from sliding along the warehouse body 830, thereby further improving the firmness of the connection between the rotating seat 820, the warehouse body 830 and the chuck 834.

[0078] In some embodiments, a plug hole 832 is provided at one end of the housing 830 close to the base 810 , and a stop rod 833 for blocking the capsule is inserted into the plug hole 832 .

[0079] Specifically, see Figure 8-Figure 10 In the feeding unit 8, if there is a bin 830 containing unused capsules, in order to prevent the capsules in the bin 830 from falling out, a lever 833 can be inserted and matched at one end of the bin 830 close to the dispensing unit 7 to block the capsules and limit the capsules from falling. Each bin 830 can be provided with a plug hole 832 matched with the lever 833. According to the actual application of the capsule replenishing unit, a suitable number of levers 833 can be selected to cooperate with the feeding unit 8. In addition, in order to prevent the lever 833 from falling off, An anti-slip protrusion can be provided on the gear rod 833, and the structure of the socket 832 is adapted to the structure of the anti-slip protrusion. When the gear rod 833 is inserted into the interior of the warehouse body 830 through the socket 832, the gear rod 833 is rotated, and the gear rod 833 is limited by the limiting protrusion on the gear rod 833 to prevent the gear rod 833 from slipping out of the socket 832; when taking out the gear rod 833, the gear rod 833 is rotated and the limiting protrusion is aligned with the socket 832, and the gear rod 833 is pulled out of the socket 832, thereby releasing the blocking effect of the gear rod 833 on the capsule in the warehouse body 830.

[0080] In some embodiments, the warehouse body 830 is detachably connected to the rotating seat 820 , and a packaging film 837 for blocking capsules is provided at one end of the warehouse body 830 close to the base 810 .

[0081] Specifically, see Fig.12 and Fig.13By setting the bin body 830 and the rotating seat 820 to be detachably connected, it is convenient to replace the bin body 830 set on the rotating seat 820, reduce the difficulty of replacing capsules in the coffee machine, and effectively shorten the replacement time of capsules; wherein, in order to prevent the capsules in the bin body 830 from leaking during installation, a packaging film 837 is provided at one end of the bin body 830 close to the base 810 to block the capsules in the bin body 830; after the bin body 830 is installed, the blocking effect of the packaging film 837 on the bin body 830 is released, so that the capsules enter the dispensing unit 7 from the bin body 830.

[0082] It should be noted that, since the packaging film 837 at one end of the chamber body 830 close to the base 810 is used to block the capsule inside, the packaging film 837 can cover part of the end surface of the open end of the chamber body 830, or the entire end surface of the open end; Fig.13 As shown, in order to reduce the packaging cost and packaging difficulty, and reduce the difficulty of removing the packaging capsule, the packaging film 837 can use a strip tape to package the warehouse body 830, wherein the tape can be a packaging tape made of organic materials such as oily acrylate and polypropylene, or a packaging tape supported by inorganic materials such as tin foil or aluminum foil, which will not be repeated here.

[0083] In some embodiments, the feeding unit 8 also includes a clamping portion 850, a locking portion 860 and a limiting portion 870; a plurality of clamping portions 850 are arranged on the rotating seat 820, and any clamping portion 850 is respectively arranged around a release port, and the opening of the clamping portion 850 is arranged toward the center area away from the rotating seat 820, so as to clamp the warehouse body 830 with the clamping portion 850; the locking portion 860 is arranged on the inner side wall of the clamping portion 850, and the locking portion 860 is adapted to the locking groove 861 arranged on the side wall of the warehouse body 830, so as to lock the warehouse body 830 in the clamping portion 850; the limiting portion 870 is arranged in the edge area of ​​the rotating seat 820, and the limiting portion 870 is provided with a limiting surface for limiting the warehouse body 830, and the limiting surface is arranged toward the opening of the clamping portion 850.

[0084] Specifically, see Figure 12-14, the bin body 830 in the feeding unit 8 is in the clamping part 850 arranged on the rotating seat 820, and the bin body 830 and the clamping part 850 are detachably connected to each other, so as to replace the bin body 830, reduce the difficulty of replenishing capsules, and shorten the time of replenishing capsules for the feeding unit 8; wherein, the clamping part 850 arranged on the rotating seat 820 and corresponding to the release port can accommodate the bin body 830 containing capsules, so as to clamp the bin body 830 in the clamping part 850; by arranging a locking part 860 on the inner wall of the clamping part 850, the bin body 830 located in the clamping part 850 can be locked, thereby improving the firmness of the installation of the bin body 830 and avoiding the rotating seat 82 0When the bin body 830 rotates, it becomes loose or detached, affecting the normal supply of capsules; and a limiting portion 870 is arranged at the edge area of ​​the rotating seat 820, and a limiting surface facing the opening of the clamping portion 850 is provided on the limiting portion 870 to avoid misalignment between the bin body 830 and the clamping portion 850 during installation, ensuring that the open end of the bin body 830 close to the base 810 corresponds to the release port, thereby improving the installation accuracy of the bin body 830, and when the bin body 830 is disassembled, the limiting surface provided on the limiting portion 870 can limit the swing amplitude of the bin body 830, thereby preventing the bin body 830 from sliding against the side wall of the clamping portion 850 due to excessive swing amplitude when the bin body 830 is disassembled.

[0085] Exemplarily, when replacing the bin body 830, the user can hold the end of the bin body 830 away from the base 810 and apply an external force toward the side away from the central area of ​​the rotating base 820. Under the action of the external force, the locking groove 861 provided on the side of the bin body 830 disengages from the locking portion 860 provided on the inner wall of the clamping portion 850, thereby releasing the locking effect on the bin body 830. At the same time, the limiting surface on the limiting portion 870 can limit the bin body 830 to prevent the bin body 830 from swinging too much when the bin body 830 is disassembled, thereby avoiding the bin body 830 from swinging too much. The body 830 and the clamping portion 850 produce sliding friction. At this time, the user can take the warehouse body 830 out of the clamping portion 850, and insert the warehouse body 830 to be replaced along the opening of the clamping portion 850 at an angle, and push the warehouse body 830 to move to the side close to the clamping portion 850 so that the warehouse body 830 is clamped in the clamping portion 850. At the same time, the limiting portion 870 limits the bottom end of the warehouse body 830, and makes the locking portion 860 cooperate and embed into the locking groove 861 on the side wall of the warehouse body 830, thereby completing the replacement of the warehouse body 830.

[0086] In some embodiments, the feeding unit 8 also includes a cutter 880, which is fixedly connected to the inner wall of the clamping portion 850 near the center area of ​​the rotating seat 820, and the working end of the cutter 880 is set to face the side away from the base 810, and the orthographic projection of the cutter 880 on the base 810 does not overlap with the orthographic projection of the capsule in the warehouse body 830 on the base 810.

[0087] Specifically, see Fig.14The cutter 880 in the feeding unit 8 can cut off the packaging film 837 on the bin body 830 in the clamping part 850, and remove the blocking effect of the packaging film 837 at the open end of the bin body 830, so that the installed capsule can be put into the dispensing unit 7 from the bin body 830; wherein the cutter 880 is arranged on the side wall of the clamping part 850, and the orthographic projection of the cutter 880 on the base 810 does not overlap with the orthographic projection of the capsule in the bin body 830 on the base 810, so the cutter 880 can cut off the packaging film 837 in the clamping part 850. When the packaging film 837 is cut, it will not cut the capsule coming out of the open end, nor will it affect the obstruction of the capsule that is about to be released; illustratively, after the user inserts the warehouse body 830 into the clamping portion 850, the open end of the warehouse body 830 is in contact with the cutter 880. As the warehouse body 830 is continuously inserted, the cutter 880 can pierce and cut the packaging film 837. The cut packaging film 837 will not have a blocking effect on the open mouth of the warehouse body 830, so the capsule can enter the dispensing unit 7 from the warehouse body 830.

[0088] It should be noted that in order to enable the tool 880 to successfully cut through the packaging film 837, the working end of the tool 880 can be provided with at least one tip portion to improve the cutting ability of the tool 880 on the packaging film 837. For example, the tool 880 can be set as a blade with an edge inclined along one side, or it can be set as a blade with a serrated edge.

[0089] In some embodiments, the coffee machine further includes an in-place detection sensor 9, which is disposed on the side of the bin body 830 away from the base 810 and is used to detect the insertion status of the bin body in the clamping portion 850. Fig.15 ;

[0090] Specifically, see Fig.17 When the bin body 830 is inserted into the clamping part 850, the insertion status of the bin body 830 is detected by the in-place detection sensor arranged at the end of the bin body 830 away from the base 810, and the in-place detection sensor 9 can be arranged beside the bin body 830, and confirm whether the bin body 830 is inserted in place in the clamping part 850 according to the current position of the bin body 830, so as to ensure the firmness of the connection between the bin body 830 and the clamping part 850; when the in-place detection sensor detects that the bin body 830 is not inserted in place, the detection sensor can transmit the detection signal to the controller, and the controller can control the feeding unit 8 and the distribution unit 7 to keep the working state stopped, and feed back the detection signal to the user in the form of sound or text through the sound module or the display module, so as to remind the user to adjust the installation status of the bin body 830. It should be noted that the in-place detection sensor 9 can be an induction switch. When the induction switch is close to the bin body 830, if the induction switch can detect the bin body 830, it means that the bin body 830 has been inserted in place in the clamping part 850 at this time.

[0091] In some embodiments, the distribution unit 7 also includes a second identification plate 822 and a second sensor 823. The second identification plate 822 is arranged on the rotating seat 820, and the second identification plate 822 is arranged opposite to the warehouse body 830; the second sensor 823 is arranged next to the rotating seat 820 for detecting the second identification plate 822.

[0092] Specifically, see Fig. 9 ; The second identification plate 822 connected to the rotating seat 820 is detected by the second sensor 823, so as to determine the delivery status of the capsule by the detection result of the second identification plate 822. Exemplarily, a second identification plate 822 can be provided on the rotating seat 820, and the second identification plate 822 is arranged opposite to one of the bins 830. When the second driving member 840 can drive the rotating seat 820 to rotate on the base 810, the second identification plate 822 leaves the detection area of ​​the second sensor 823. At this time, the rotating seat 820 has switched the current bin 830, and the capsule is provided to the dispensing unit 7 through other bins 830. As the rotating seat 820 continues to rotate, the second identification plate 822 returns to the original position and is detected by the second sensor 823. At this time, the rotating seat 820 switches the bin 830 in the original position to the initial position.

[0093] In some embodiments, the feeding unit 8 further includes a gear 841 and a gear ring 842 ; the gear 841 is fixedly connected to the output shaft of the second driving member 840 ; the gear ring 842 is fixedly connected to the rotating seat 820 , and the gear ring 842 is meshed with the gear 841 .

[0094] Specifically, see Figure 15-16 The second driving member 840 can drive the rotating seat 820 to rotate on the base 810 through the mutually meshing gear 841 and the ring gear 842, so as to drive the warehouse body 830 on the rotating seat 820 to rotate, so as to switch the warehouse body 830 corresponding to the release port; wherein, when the second driving member 840 is in operation, it can drive the gear 841 to rotate through the output shaft, so that the rotating gear 841 and the ring gear 842 move relative to each other. Since the ring gear 842 is fixedly connected to the rotating seat 820, it drives the rotating seat 820 connected to the ring gear 842 to rotate, so that the warehouse bodies 830 evenly distributed on the rotating seat 820 rotate, so as to realize the switching of the warehouse bodies 830.

[0095] In some embodiments, the coffee machine further includes a distance measuring sensor 10, which is arranged above the end of the chamber 830 away from the base 810, and is used to measure the distance between the capsule in the chamber 830 away from the base 810 and the distance measuring sensor 10, thereby obtaining the number of capsules in the chamber 830; specifically, please refer to Fig.18By using the distance measuring sensor 10, the distance between the capsule at one end of the bin body 830 away from the base 810 and the distance measuring sensor 10, that is, the distance between the top capsule and the distance measuring sensor 10 can be measured. Since each capsule has a fixed size, the number of capsules in the bin body 830 can be obtained by obtaining the distance between the top capsule in the bin body 830 and the distance measuring sensor 10. In other words, the greater the distance between the top capsule and the distance measuring sensor 10, the fewer capsules in the bin body 830. Therefore, the distance measuring sensor 10 is used to detect the storage status of the capsules in the bin body 830 so as to fill the capsules to be distributed in time.

[0096] In some embodiments, the coffee machine further includes an identification sensor 11, which is arranged on the side of the bin 830 away from the base 810, and is used to identify the bin 830 containing different types of capsules. Fig.18 For example, to distinguish different types of coffee capsules, the warehouse body 830 can be set to different colors. In this case, the recognition sensor can be set as a color sensor, which can collect the color of the warehouse body 830 and identify the type of the capsule inside it according to the color of the warehouse body 830; for another example, to distinguish different types of coffee capsules, different QR codes or bar codes are marked on the warehouse body 830. In this case, the recognition sensor can be set as a scanner, which can scan the QR code or bar code on the warehouse body 830 and determine the type of the capsule inside it according to the QR code or bar code on the warehouse body 830.

[0097] It should be noted that, when the warehouse body 830 and the rotating seat 820 are set to be fixedly connected, the blocking portion 831 is a cover body detachably connected to the warehouse body 830 to avoid affecting the filling of capsules into the warehouse body 830; when the warehouse body 830 and the rotating seat 820 are set to be detachably connected, the blocking portion 831 can be a blocking plate fixedly connected to the warehouse body 830, or adhered to a transparent film layer at one end of the warehouse body 830 away from the base 810; wherein, when the coffee machine is working, the warehouse body 831 can be removed. 0 is far away from the blocking portion 831 at one end of the base, or a transparent blocking portion 831 with a blocking effect is used, such as a transparent cover, a blocking plate or a plastic film, to avoid blocking the distance measuring sensor 10 and preventing it from affecting its counting of the number of capsules; in addition, a shell can be provided on the feeding unit 8 to match the cover, and the distance measuring sensor 10, the identification sensor 11 and the in-position detection sensor 9 can be arranged at corresponding positions on the side wall of the shell to ensure that the three can work stably at corresponding positions, which will not be repeated here.
