Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more particularly to a brewing machine with a hydraulic system. Background Technology

[0002] Capsule beverage brewing machines are popular among users because they are more convenient and hygienic than manual brewing. The main reason why machine brewing is faster than manual brewing is that the brewing system formed by the machine and capsules applies pressure to the beverage ingredients placed inside the machine. The pressure promotes the extraction of effective substances from the beverage ingredients. The pressurized brewing of capsule beverages is completed within the machine's brewing chamber. The brewing pressure of capsule beverages is mostly in the range of 3-12 bar, which requires the brewing chamber to have reliable pressure resistance. If the pressure resistance fails, problems such as chamber bursting and leakage, and hot water splashing may occur during the brewing process, posing a significant safety hazard.

[0003] Existing high-pressure brewing systems mostly employ manual, purely mechanical locking structures or motor-controlled locking structures. Manual, purely mechanical locking structures (such as handle-type) require considerable force to operate, resulting in poor convenience. While motor-controlled locking structures are less strenuous than manual locking, they increase equipment costs, and the drive components (such as the motor) require a certain amount of time to operate, leading to slower and less immediate action. Therefore, regardless of the method used, neither can efficiently create a stable, pressure-resistant environment within the brewing chamber.

[0004] Currently, there is no effective solution to the problem that existing brewing machines cannot efficiently create a stable and pressure-resistant environment when brewing high-pressure capsules due to poor ease of operation and high cost.

[0005] Therefore, the present invention proposes a brewing machine with a hydraulic system to solve at least one of the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a brewing machine with a hydraulic system. The connecting rod structure cooperates with the hydraulic structure to lock and open the brewing chamber, enabling effective brewing of high-pressure capsules. At the same time, it is easy and labor-saving to operate, the equipment has higher reliability during the brewing process, and it has the advantage of low cost.

The sliding sealing assembly can slide between at least a first station and a second station. When the sliding sealing assembly is at the first station, the sliding base is separated from the sealing cover, and the space between them is connected to the capsule dispensing port, so that the brewing capsule inserted through the capsule dispensing port can fall into the space between the sliding base and the sealing cover. When the sliding sealing assembly slides towards the fixed sealing assembly to the second station, the sliding base and the sealing cover enclose a brewing cavity that matches the shape of the brewing capsule, and the pre-inserted brewing capsule is located in the brewing cavity. The sliding base has a sealed pressurized space on the side opposite to the sealing cover. The pressurized space is connected to the water tank or an external water source through a pressure inlet. Water is supplied to the pressurized space through the water tank or the external water source to increase the pressure in the pressurized space and push the sliding base toward the sealing cover. This provides continuous pressure for the sliding base and the sealing cover to seal together, so that the brewing chamber is in a compressed and sealed state when brewing the brewing capsule.

[0020] In a preferred embodiment of the present invention, the pressure water inlet is disposed on the sealing base, and the water inlet needle has a water inlet pipe communicating with its needle tip. The brewing machine with a hydraulic system also includes a multi-way valve, which has at least a first port, a second port, a third port, and a fourth port. The water supply port of the water tank is connected to the first port via a first water pump, the pressurized space is connected to the second port via a pressure inlet, and the water inlet pipe is connected to the third port. A flow meter is installed on the pipeline between the water supply port of the water tank and the first water pump.

[0021] In a preferred embodiment of the present invention, a back pressure check valve and a heating element are sequentially provided between the third port and the water inlet pipe. When the water pressure in the water circuit reaches the preset pressure, the back pressure check valve is opened so that the water flows through the heating element and is heated to the preset temperature before entering the brewing chamber through the water inlet pipe.

[0022] In a preferred embodiment of the present invention, a second water pump is provided at the water inlet of the water tank, and the second water pump is used to replenish the water tank with water from an external water source.

[0023] In a preferred embodiment of the present invention, the water tank has a liquid level detection element; The brewing machine with a hydraulic system also includes a controller.

[0024] In a preferred embodiment of the present invention, the brewing machine with a hydraulic system further includes a first three-way valve, two of the water inlets of the first three-way valve being connected to the water outlet of the second water pump and the water inlet of the water tank, respectively, and the other water inlet of the first three-way valve being connected to the fourth port of the multi-way valve, through which the pressure in the pressurized space is released into the water tank.

[0025] In a preferred embodiment of the present invention, the brewing machine with a hydraulic system further includes a recovery chamber; The sliding base has a water outlet pipe that communicates with the brewing chamber. A second three-way valve is provided at the water outlet on the main unit housing. The two water outlets of the second three-way valve are respectively connected to the water outlet pipe and the water outlet on the main unit housing. The other water outlet of the second three-way valve is connected to the recycling bin through a third water pump.

[0026] In a preferred embodiment of the present invention, the brewing machine with a hydraulic system further includes a controller, the control signal output terminal of which is electrically connected to the control terminal of the second three-way valve to control the water outlet of the water pipe.

[0027] As described above, the features and advantages of the brewing machine with a hydraulic system of the present invention are: Inside the main unit casing, there is a fixed sealing component and a sliding sealing component that can slide relative to the fixed sealing component. The fixed sealing component has a sealing cover, and the sliding sealing component has a movable sliding base. The sliding sealing component can slide between at least a first station and a second station. When the sliding sealing component is in the first station, the sliding base is separated from the sealing cover, and the space between them is connected to the capsule dispensing port. In this state, a brewing capsule can be dispensed into the space between the sliding base and the sealing cover through the capsule dispensing port. After the brewing capsule falls into the space between the sliding base and the sealing cover, the sliding sealing component can be controlled to slide towards the fixed sealing component. When the sliding sealing component slides to the second station, the sliding base and the sealing cover form a brewing cavity that matches the shape of the brewing capsule. The pre-dispensed brewing capsule is located in the brewing cavity, which enables the brewing operation of the brewing capsule.

[0028] To create a stable and pressure-resistant environment within the brewing chamber, this invention features a sealed pressurized space on the side of the sliding base opposite the sealing cap. Water can be supplied to this pressurized space via a water tank or external water source to increase the pressure within the space and push the sliding base to move slightly towards the sealing cap. This allows the sliding base and sealing cap to work together to provide continuous pressure to the brewing capsule, ensuring the brewing chamber remains tightly sealed during brewing and guaranteeing stable pressure resistance. The sliding sealing assembly allows for easy and effortless opening and closing of the brewing chamber, which is also highly reliable during brewing. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0032] It should be noted that when a component is said to be "set on" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] In this invention, terms such as "up," "down," "left," and "right," which indicate direction, are all used in this way. Figure 9 The directions "up", "down", "left", and "right" shown are for illustrative purposes only and are explained here to more clearly illustrate the structure of the brewing machine.

[0035] like Figures 1 to 20 As shown, the present invention provides a brewing machine with a hydraulic system, which includes a water tank 6, a main housing 5, a fixed sealing assembly 1, and a sliding sealing assembly 2. The main housing 5 is located on one side of the water tank 6 (e.g., the main housing 5 and the water tank 6 can be arranged side by side), and the top of the main housing 5 has a capsule dispensing port 4. The fixed sealing assembly 1 and the sliding sealing assembly 2 are both located inside the main housing 5, and are distributed left and right. The fixed sealing assembly 1 has a sealing cover 101, and the sliding sealing assembly 2 has a sliding base 201 that can move left and right. The sliding sealing assembly 2 can slide at least between a first position and a second position. When the sliding sealing assembly 2 is located at... At the first station on the left, the sliding base 201 is separated from the sealing cover 101. The capsule dispensing port 4 is located above the space between the sliding base 201 and the sealing cover 101, and the space between them is connected to the capsule dispensing port 4. The brewing capsule 28 can be dispensed through the capsule dispensing port 4, and the brewing capsule 28 can fall into the space between the sliding base 201 and the sealing cover 101 from the capsule dispensing port 4. When the sliding sealing assembly 2 slides to the second station in the direction of the fixed sealing assembly 1, the sliding base 201 and the sealing cover 101 enclose and form a brewing cavity 3 that matches the shape of the brewing capsule 28. The pre-dispensed brewing capsule 28 is located in the brewing cavity 3, and the brewing capsule 28 can be locked by the brewing cavity 3.

[0036] In addition, since there is a sealed pressurized space 202 on the side of the sliding base 201 that is outside the sealing cover 101 (i.e., the left side of the sliding base 201), the pressurized space 202 is connected to the water tank 6 or an external water source through the pressure water inlet 203. Before brewing the capsule 28, water can be supplied to the pressurized space 202 through the water tank 6 or an external water source to increase the pressure in the pressurized space 202 and push the sliding base 201 to move towards the sealing cover 101. This provides continuous pressure for the sealing fit between the sliding base 201 and the sealing cover 101, so that the brewing chamber 3 is in a compressed and sealed state when brewing the capsule 28.

[0037] In this invention, a fixed sealing component 1 and a sliding sealing component 2 that can slide relative to the fixed sealing component 1 are provided inside the main casing 5. The fixed sealing component 1 has a sealing cover 101, and the sliding sealing component 2 has a movable sliding base 201. The sliding sealing component 2 can slide at least between a first working position and a second working position. When the sliding sealing component 2 is located at the first working position, the sliding base 201 is separated from the sealing cover 101, and the space between them is connected to the capsule dispensing port 4. In this state, the capsule dispensing port 4 can be used to dispense the brewing capsule 28 into the space between the sliding base 201 and the sealing cover 101. After the brewing capsule 28 falls into the space between the sliding base 201 and the sealing cover 101, the sliding sealing component 2 can be controlled to slide towards the fixed sealing component 1. When the sliding sealing component 2 slides to the second working position, the sliding base 201 and the sealing cover 101 form a brewing cavity 3 that matches the shape of the brewing capsule 28. The pre-dispensed brewing capsule 28 is located in the brewing cavity 3, which can realize the brewing operation of the brewing capsule 28. To create a stable and pressure-resistant environment within the brewing chamber 3, this invention features a sealed pressurized space 202 on the side of the sliding base 201 opposite to the sealing cover 101. Water can be supplied to the pressurized space 202 via the water tank 6 or an external water source to increase the pressure within the pressurized space 202 and push the sliding base 201 to move slightly towards the sealing cover 101. This allows the sliding base 201 and the sealing cover 101 to provide continuous pressure to the brewing capsule 28, ensuring that the brewing chamber 3 remains in a tightly sealed state during brewing of the capsule 28, thus guaranteeing stable pressure resistance. The sliding sealing assembly 2 allows for convenient and effortless opening of the brewing chamber 3 from the capsule 28, while also providing higher reliability during brewing.

[0038] The brewing capsule 28 in this invention can be, but is not limited to, a tea capsule. Of course, it can also be a capsule filled with coffee powder or other beverage solid particles. The type of brewing capsule 28 is not limited here. The following description uses a tea capsule as an example only.

[0039] In an optional embodiment of the present invention, such as Figure 9 , Figure 10 , Figure 14 and Figure 17As shown, the fixed sealing assembly 1 also includes an elastic sealing element 102. The sealing cover 101 is a vertically arranged disc-shaped structure, while the sliding base 201 is a cylindrical structure with a closed left end and an open right end. A fixed bracket 25 is provided inside the main unit housing 5. The sealing cover 101 is fixed to the fixed bracket 25. The elastic sealing element 102 is embedded inside the sealing cover 101. At least a portion of the elastic sealing element 102 extends to the outside of the sealing cover 101 and forms a first sealing ring 1021 that matches the mating position of the sliding base 201. When the sliding sealing assembly 2 slides to the second position, the edge of the open right end of the sliding base 201 seals against the first sealing ring 1021, thereby ensuring a stable seal at the joint between the fixed sealing assembly 1 and the sliding sealing assembly 2, that is, ensuring that the brewing chamber 3 has good sealing performance.

[0040] Furthermore, such as Figure 9 , Figure 10 , Figure 14 and Figure 17 As shown, the elastic seal 102 has a water inlet needle 103. The needle tip of the water inlet needle 103 passes through the elastic seal 102 and the sealing cover 101 sequentially to the left and extends to the outside of the sealing cover 101. When the sliding sealing assembly 2 slides towards the fixed sealing assembly 1, the needle tip of the water inlet needle 103 punctures the brewing capsule 28. A pressure water inlet hole 203 is provided on the sliding base 201, and the water inlet needle 103 has a water inlet pipe 17 communicating with its needle tip. During the operation of the brewing machine, when the needle tip of the water inlet needle 103 punctures the brewing capsule 28, water is injected into the brewing chamber 3 through the water inlet pipe 17, thereby achieving the purpose of brewing.

[0041] In an optional embodiment of the present invention, such as Figure 9 , Figure 10 and Figure 17As shown, the sliding sealing assembly 2 also includes a sealing base 204, which is a cylindrical structure with one end closed and the other end open. A fixed bracket 25 is provided inside the main housing 5, and the sealing base 204 is slidably mounted on the fixed bracket 25. The sliding base 201 has a protrusion at its end away from the sealing cover 101. The protrusion is slidably embedded in the sealing base 204 through the open end of the sealing base 204. The protrusion can slide left and right within the sealing base 204 to form the aforementioned pressurized space 202 between the protrusion and the inner wall of the sealing base 204. When the brewing machine is in operation, water continuously enters the pressurized space 202 through the pressure inlet hole 203 until the continuous water flow in the pressurized space 202 creates sufficient internal pressure to push the sliding base 201 to move to the right and press more tightly against the sealing cover 101. At this time, the brewing capsule 28 located in the brewing chamber 3 is compressed (in this state, continuous water intake maintains the compressed state, and the compressed state disappears when water intake stops), thereby creating a high-pressure environment for brewing and ensuring the high-pressure stability of the brewing environment. It should be noted that the sliding sealing component 2 only moves a small amount within a small range. Its function is to continuously generate pressure through water pressure to seal the brewing capsule 28 under high pressure, creating a high-pressure, sealed brewing environment for it.

[0042] Furthermore, such as Figure 9 , Figure 10 and Figure 17 As shown, the sealing base 204 has multiple elongated limiting holes 2041 extending along the sliding direction of the sliding sealing assembly 2. These limiting holes 2041 are spaced apart circumferentially along the sealing base 204. The outer wall of the protruding portion has limiting protrusions 2011 that are aligned with the limiting holes 2041. These limiting protrusions 2011 are slidably embedded within their respective limiting holes 2041. Through the cooperation of the limiting protrusions 2011 and the limiting holes 2041, the sliding of the sliding sealing assembly 2 is limited, preventing it from exceeding a preset range during sliding, thereby ensuring the stable operation of the hydraulic system.

[0043] Furthermore, such as Figure 9 , Figure 10 and Figure 17 As shown, a second sealing ring 205 is provided inside the sealing base 204. The second sealing ring 205 is pressed tightly between the inner wall of the sealing base 204 and the protrusion to ensure that the connection between the sealing base 204 and the sliding base 201 is in a stable and sealed state, so as to ensure the sealing effect of the pressurized space 202.

[0044] In an optional embodiment of the present invention, such as Figure 9 , Figure 10 , Figure 15 and Figure 17As shown, the sliding base 201 has a water-discharging piercing knife 206, which is positioned towards the brewing chamber 3. When the sliding sealing assembly 2 slides towards the fixed sealing assembly 1, the water-discharging piercing knife 206 pierces the brewing capsule 28. Because the brewing capsule 28 has a certain elasticity, after the water-discharging piercing knife 206 pierces the brewing capsule 28, the pierced position remains closed due to the elasticity of the brewing capsule 28. When the pressurized water injected into the brewing chamber 3 reaches a preset pressure value, the water pressure inside the brewing capsule 28 will open the pierced position, allowing water to flow out. Since the brewing capsule 28 is always in a brewing state before the pierced position is opened, the brewing operation is completed when water flows out from the pierced position.

[0045] In an optional embodiment of the present invention, such as Figures 9 to 13 , Figure 15 and Figure 16 As shown, the sealing base 204 has at least two base guide posts 2042, and the interior of the main unit housing 5 or the fixed bracket 25 has a first slide rail 8 extending along the sliding direction of the sliding sealing assembly 2. The base guide posts 2042 are slidably embedded in the first slide rail 8. This achieves sliding guidance for the sealing base 204 (i.e., the entire sliding sealing assembly 2).

[0046] Specifically, the sealing base 204 has two base guide posts 2042 on each side. The two base guide posts 2042 on one side of the sealing base 204 are arranged side by side and spaced apart in the horizontal direction, so as to limit and guide the sealing base 204 and ensure that the sealing base 204 can only slide left and right in the horizontal direction along the first slide rail 8 during the sliding process.

[0047] In an optional embodiment of the present invention, such as Figures 1 to 9 , Figure 12 , Figure 13 , Figures 15 to 17 As shown, the brewing machine with a hydraulic system also includes a linkage assembly 9, which serves as a control component. The user can control the sliding sealing assembly 2 to slide between the first and second workstations via the linkage assembly 9.

[0048] Specifically, such as Figures 1 to 9 , Figure 12 , Figure 13 , Figures 15 to 17As shown, the linkage assembly 9 includes a handle 901, a handle connecting shaft 902, a rocker arm 903, and a connecting rod 904. The handle 901 is located outside the main housing 5, and the handle connecting shaft 902 is located inside the main housing 5. Both ends of the handle connecting shaft 902 are rotatably connected to the main housing 5. The extension direction of the handle 901 is perpendicular to the extension direction of the handle connecting shaft 902, and one end of the handle 901 is connected to the handle connecting shaft 902. The extension direction of the rocker arm 903 is perpendicular to the extension direction of the handle connecting shaft 902, and one end of the rocker arm 903 is fixedly connected to the handle connecting shaft 902. One end of the connecting rod 904 is rotatably connected to the other end of the rocker arm 903, and the other end of the connecting rod 904 is rotatably sleeved on the bottom support guide post 2042. During use, the user can rotate the handle 901 to tilt the rocker arm 903 and the connecting rod 904 upward or downward by a preset swing angle while simultaneously moving them horizontally, thereby causing the sliding sealing assembly 2 to slide from the first position to the second position. In this invention, the linkage assembly 9 cooperates with the hydraulic system (i.e., the fixed sealing assembly 1 and the sliding sealing assembly 2 and the corresponding pipelines) to achieve sealing and locking of the brewing chamber 3 and easy opening, which enables effective brewing of the brewing capsule 28 in a high-pressure environment. At the same time, the operation is convenient and labor-saving, the equipment operation is more reliable during the brewing process, and it has the advantage of low cost.

[0049] Specifically, Figure 12 , Figure 13 , Figure 15 and Figure 16 As shown, the rocker arm 903 is flat, with one end fixedly sleeved on the handle connecting shaft 902. Two protrusions are respectively located on the two opposite side walls of the other end of the rocker arm 903. There are two connecting rods 904. One end of each connecting rod 904 is rotatably sleeved on the corresponding protrusion, and the other end of each connecting rod 904 is rotatably sleeved on the bottom support guide post 2042 located on both sides of the sealing bottom support 204. The above structure can realize the stable transmission of driving force.

[0050] In an optional embodiment of the present invention, such as Figures 4 to 7 , Figure 9 , Figure 10 and Figure 12As shown, the brewing machine with a hydraulic system also includes a sliding cover assembly 7, which is connected to a sliding sealing assembly 2. When the sliding sealing assembly 2 is in the first position, the sliding cover assembly 7 slides to one side of the capsule dispensing port 4, at which point the sliding cover assembly 7 does not block the capsule dispensing port 4. When the sliding sealing assembly 2 slides to the second position, the sliding cover assembly 7 slides to the capsule dispensing port 4, at which point the sliding cover assembly 7 blocks the capsule dispensing port 4. Because the sliding cover assembly 7 is connected to the sliding sealing assembly 2, the opening or closing action of the sliding cover assembly 7 can be achieved by operating the handle 901, making operation more convenient.

[0051] Furthermore, such as Figures 4 to 7 , Figure 9 , Figure 10 and Figure 12 As shown, the sliding cover assembly 7 includes a cover 701 and two second slide rails 702. A cover connecting post 2043 is provided vertically on the top of the sealing base 204, and the cover 701 is located on the top of the cover connecting post 2043. The two second slide rails 702 are provided horizontally on the fixed bracket 25 inside the main unit housing 5, and the two second slide rails 702 are respectively located on both sides of the cover 701. The two opposite edges of the cover 701 are slidably embedded in the corresponding second slide rails 702, which serve as guides for the opening and closing of the cover 701.

[0052] In an optional embodiment of the present invention, such as Figure 10 , Figure 14 and Figure 17 As shown, a dot matrix recognition element 10 is provided at the center of the sealing cap 101 facing the brewing chamber 3. The dot matrix recognition element 10 is used to identify the dot matrix recognition code preset on the brewing capsule 28, and to obtain the parameter information for brewing the brewing capsule 28 through the dot matrix recognition element 10. The parameter information includes at least the amount of water and the water temperature required for brewing the brewing capsule 28.

[0053] The dot matrix recognition element 10 can be, but is not limited to, an optical recognition sensor.

[0054] In an optional embodiment of the present invention, such as Figure 11As shown, a Hall sensor 11 is installed on the main unit housing 5, and a magnet 12 is installed on the bottom guide post 2042 of the sealed base 204. When the sliding sealing assembly 2 slides towards the fixed sealing assembly 1 to the second position, the magnet 12 is within the sensing range of the Hall sensor 11, thereby controlling the dot matrix recognition element 10 to start. When the magnet 12 moves out of the sensing range of the Hall sensor 11, the dot matrix recognition element 10 stops working. Of course, the positions of the Hall sensor 11 and the magnet 12 can also be interchanged, that is, the magnet 12 can be installed on the main unit housing 5, and the Hall sensor 11 can be installed on the bottom guide post 2042 of the sliding base 201.

[0055] Furthermore, such as Figure 18 and Figure 19 As shown, the brewing machine with a hydraulic system also includes a controller 13 and a heating element 19 for controlling water temperature. The detection signal output terminal of the Hall sensor 11 is electrically connected to the detection signal receiving terminal of the controller 13. The control signal output terminal of the controller 13 is electrically connected to the control terminal of the dot matrix recognition element 10. The detection signal output terminal of the dot matrix recognition element 10 is electrically connected to the detection signal receiving terminal of the controller 13. The control signal output terminal of the controller 13 is electrically connected to the control terminal of the heating element 19. After the Hall sensor 11 collects the detection signal, it can transmit the signal to the controller 13. The controller 13 then controls the working state of the dot matrix recognition element 10. After the dot matrix recognition element 10 recognizes the mark on the brewing capsule 28, it transmits the detection signal to the controller 13. The controller 13 retrieves the corresponding parameters for brewing the brewing capsule 28 and controls the heating element 19 according to the corresponding parameters to heat the water to the preset temperature.

[0056] The heating element 19 may be, but is not limited to, a heating pot mounted on a fixed bracket 25.

[0057] In an optional embodiment of the present invention, such as Figure 5 , Figure 6 and Figure 20 As shown, the pressure inlet 203 is located on the sealing base 204, and the inlet needle 103 has an inlet pipe 17 communicating with its needle head; in addition, the brewing machine with a hydraulic system also includes a multi-way valve 14, which has at least a first port 1401, a second port 1402, a third port 1403 and a fourth port 1404. The water supply port of the water tank 6 is connected to the first port 1401 through the first water pump 26, the pressurized space 202 is connected to the second port 1402 through the pressure inlet 203, and the inlet pipe 17 is connected to the third port 1403; a flow meter 27 is installed on the pipe between the water supply port of the water tank 6 and the first water pump 26.

[0058] Among them, such as Figure 20As shown, a back pressure check valve 18 and a heating element 19 are sequentially provided between the third port 1403 and the water inlet pipe 17. When the water pressure in the water circuit reaches the preset pressure, the back pressure check valve 18 is opened so that the water flows through the heating element 19 and is heated to the preset temperature before entering the brewing chamber 3 through the water inlet pipe 17.

[0059] Furthermore, such as Figure 5 , Figure 6 , Figure 19 and Figure 20 As shown, a second water pump 15 is installed at the inlet of the water tank 6. The second water pump 15 is used to replenish water from an external water source into the water tank 6.

[0060] Furthermore, such as Figure 19 As shown, the water tank 6 contains a liquid level detection element 29; the brewing machine with a hydraulic system also includes a controller 13. The detection signal output terminal of the liquid level detection element 29 is electrically connected to the detection signal receiving terminal of the controller 13, and the control signal output terminal of the controller 13 is electrically connected to the control terminal of the second water pump 15. The controller 13 controls the second water pump 15 to replenish water into the water tank 6, so that the liquid level in the water tank 6 is within a preset liquid level range. The liquid level detection element 29 can be, but is not limited to, a liquid level sensor.

[0061] Furthermore, such as Figure 20 As shown, the brewing machine with a hydraulic system also includes a first three-way valve 16. Two of the ports of the first three-way valve 16 are connected to the outlet of the second water pump 15 and the inlet of the water tank 6, respectively. The other port of the first three-way valve 16 is connected to the fourth port 1404 of the multi-way valve 14, through which the pressure in the pressurized space 202 is released into the water tank 6.

[0062] Furthermore, such as Figure 9 and Figure 20 As shown, the brewing machine with a hydraulic system also includes a recycling chamber 22; the sliding base 201 has a water outlet pipe 20 communicating with the brewing chamber 3, and a second three-way valve 21 is provided at the water outlet on the main unit housing 5. The two outlets of the second three-way valve 21 are connected to the water outlet pipe 20 and the water outlet on the main unit housing 5, respectively, and the other outlet of the second three-way valve 21 is connected to the recycling chamber 22 through a third water pump 23. When water needs to be dispensed, the water outlet pipe 20 is opened through the second three-way valve 21, so that water can be dispensed through the water outlet pipe 20; after the water dispensing operation is completed, the water outlet pipe 20 is connected to the recycling chamber 22 through the second three-way valve 21. At this time, the water remaining in the water outlet pipe 20 can flow to the recycling chamber 22 for centralized collection, avoiding the problem of dripping at the water outlet pipe 20 after brewing.

[0063] The brewing machine with a hydraulic system also includes a controller 13, and the second three-way valve 21 is an electromagnetic three-way valve. The control signal output terminal of the controller 13 is electrically connected to the control terminal of the second three-way valve 21 to control the water outlet pipe 20.

[0064] In an optional embodiment of the present invention, such as Figures 1 to 4 As shown, the brewing machine with a hydraulic system also includes a tray 24, which is located below the water outlet on the main housing 5.

[0065] The working principle of the brewing machine with a hydraulic system of the present invention will be described in detail below (taking brewing tea capsules as an example).

[0066] The overall working principle of the brewing machine in this invention is as follows: When brewing tea, place the cup below the tea outlet of the brewing machine (i.e., the water outlet on the main unit casing 5), and rotate the handle 901 to slide the sliding sealing component 2 away from the fixed sealing component 1 to the first position. At the same time, the cover 701 opens, and the tea capsule is inserted into the brewing chamber 3 through the capsule inlet 4. Then, rotate the handle 901 downward to slide the sliding sealing component 2 towards the fixed sealing component 1 to the second position. While the cover 701 seals the capsule inlet 4, the sliding base 201 of the sliding sealing component 2 cooperates with the sealing cover 101 of the fixed sealing component 1 to form a sealed brewing chamber 3. At this time, the tea capsule is compressed inside the brewing chamber 3. Since the parameter information can be identified by the dot matrix recognition element 10 when the tea capsule enters the brewing chamber 3, the controller 13 brews the tea capsule according to the corresponding parameters.

[0067] During the brewing process, firstly, the drinking water in the water tank 6 is pumped into the multi-way valve 14 by the first water pump 26. Part of the drinking water enters the pressurized space 202 through the second port 1402 and the pressure inlet 203 of the multi-way valve 14 to accumulate pressure, thereby pushing the sliding base 201 to move and cooperate with the sealing cover 101 to form a high-pressure seal in the brewing chamber 3. The other part of the drinking water enters the back pressure check valve 18. After reaching the predetermined critical pressure value of the back pressure check valve 18, it enters the heating element 19 to be heated to the preset temperature. Then, the hot water is transported to the brewing chamber 3 through the water inlet pipe 17 for brewing. The brewed tea in the brewing chamber 3 flows out from the position on the tea capsule punctured by the water outlet piercing knife 206 to the water outlet pipe 20, and then flows out from the tea outlet of the brewing machine into the water cup. At the end of the tea brewing process, the third water pump 23 is activated to suck up the remaining tea liquid in the water outlet pipe 20 and return it to the recycling chamber 22 for centralized collection, thus avoiding dripping from the tea outlet after brewing. When the third water pump 23 stops working, the capsule brewing process ends. At this time, the sliding sealing component 2 can be removed by turning the handle 901. Since the sliding sealing component 2 separates from the fixed sealing component 1, the used tea capsules fall into the recycling chamber 22 below, and the entire brewing process ends.

[0068] When the level detection element 29 detects that there is no water in the water tank 6, the second water pump 15 can be started to pump water from an external water source into the water tank 6 for water supply until the water level in the water tank 6 reaches the preset level height, at which point the second water pump 15 can stop working.

[0069] The operation process of the brewing machine of the present invention is as follows: The user manually inserts the tea capsule with the dot matrix identification code into the brewing chamber 3 through the capsule dispensing port 4. Then, the handle 901 is pressed down, which drives the rocker arm 903 and the connecting rod 904 to deflect downward and move to the right via the handle connecting shaft 902, so that the connecting rod assembly 9 can drive the sliding sealing assembly 2 connected to it to slide towards the fixed sealing assembly 1; when the handle 901 is in the fully pressed position (the handle 901 rotates 90° downward from the horizontal position to the vertical position), the sliding base 201 and the sealing cover 101 seal together to form a sealed brewing chamber 3. At this time, the magnet block 12 set on the bottom guide post 2042 moves to the position directly opposite the Hall sensor 11. The Hall sensor 11 opens and sends the collected detection signal to the controller 13. The controller 13 controls the dot matrix identification element 10 to start identifying the dot matrix identification code on the tea capsule. After a predetermined identification time, the dot matrix identification element 10 automatically closes, at which point the tea capsule identification is completed.

[0070] Afterwards, by pressing the tea brewing button on the main unit casing 5, the controller 13 controls the first water pump 26 to send drinking water from the water tank 6 into the multi-way valve 14. Part of the drinking water enters the pressurized space 202 through the second port 1402 and the pressure inlet 203 of the multi-way valve 14 to accumulate pressure, thereby pushing the sliding base 201 to move and cooperate with the sealing cover 101 to form a high-pressure seal in the brewing chamber 3. The other part of the drinking water enters the back pressure check valve 18. When the pressure in the pressurized space 202 accumulates, since the entire pipeline is connected, the pressure is the same everywhere in the pipeline. After reaching the predetermined critical pressure value of the back pressure check valve 18, it enters the heating element 19 to be heated to the preset temperature. Then, the hot water is transported to the brewing chamber 3 through the water inlet pipe 17 for brewing. The brewed tea soup in the brewing chamber 3 flows out from the position where the tea capsule is punctured by the water piercing knife 206 to the water outlet pipe 20, and then flows out from the tea outlet of the brewing machine into the water cup. The presence of the back pressure check valve 18 ensures that while water is supplied for brewing tea, sufficient accumulated pressure is maintained in the pressurized space 202 to achieve high-pressure sealing of the tea capsules in the brewing chamber 3.

[0071] After the tea capsules are brewed, the first water pump 26 and the second water pump 15 stop working, the fourth port 1404 of the multi-way valve 14 opens, and all the pipes in the brewing machine are instantly connected to the outside atmosphere. The residual water in the pipes enters the first three-way valve 16 through the fourth port 1404 of the multi-way valve 14 and is collected in the water tank 6. At this time, the pressurized space 202 no longer applies pressure to the brewing chamber 3 because it loses the pressure of continuous water intake. The user rotates the handle 901 in the opposite direction. The handle 901 drives the handle connecting shaft 902, rocker arm 903 and connecting rod 904 to reset. The sliding sealing component 2 returns to the first position, the brewing chamber 3 is fully opened, and the brewed waste capsules fall into the recycling bin 22 below. The entire brewing process is over.

[0072] The following explains the water supply principle of the brewing machine in this invention during operation: An external water source is connected to the water tank 6 sequentially via a second water pump 15 and a first three-way valve 16. The outlet of the water tank 6 is connected to the first water pump 26 via a flow meter 27 (used to measure the water output so that water is discharged according to the target output). This ensures that when the water tank 6 is short of water, water from the external water source can be replenished to the water tank 6 via the second water pump 15. Therefore, as long as the external water source has sufficient water, the water tank 6 can be adequately replenished, thus ensuring that the water tank 6 meets long-term water supply needs.

[0073] Since the water tank 6 is connected to the external water source through the first three-way valve 16 to the fourth port 1404 (pressure relief port) of the multi-way valve 14, the fourth port 1404 of the multi-way valve 14 can play the role of pressure relief. That is, the second port 1402 of the multi-way valve 14 is connected to the pressure inlet hole 203 of the pressurized space 202, which can be used for pressure relief of the pressurized space 202. The third port 1403 of the multi-way valve 14 is connected to the water inlet pipe 17, which is connected to the brewing chamber 3, through the back pressure check valve 18 and the heating element 19. When no water is supplied to the brewing chamber 3, the first port 1401 of the multi-way valve 14 is connected to the fourth port 1404, and the second port 1402 and the third port 1403 are closed. When the multi-way valve 14 supplies water to the brewing chamber 3, the first port 1401 is connected to the second port 1402 and the third port 1403, and the fourth port 1404 is closed, thus ensuring that the normal water supply to the brewing chamber 3 for brewing and the pressurization of the pressurization space 202 are carried out simultaneously. After brewing is completed, the fourth port 1404 is opened, so that the entire pipeline is in a connected state, and the pressure can be quickly released through the fourth port 1404, so that the brewing chamber 3 can be opened smoothly.

[0074] During the process of supplying drinking water from water tank 6 or an external water source to brewing chamber 3 via the first water pump 26, the drinking water enters the heating element 19 through the back pressure check valve 18 (the function of the back pressure check valve 18 is to ensure that water is dispensed for brewing only when a certain pressure is accumulated in the pipeline, that is, to maintain sufficient hydraulic pressure in the pressurized space 202, thereby ensuring that the tea capsule can be brewed under sufficient pressure, thus ensuring a high-pressure sealed brewing environment for the tea capsule in brewing chamber 3). After the heating element 19 heats the drinking water, the hot water enters the brewing chamber 3 (i.e., the inside of the tea capsule) from the water inlet pipe 17 to brew the tea leaves inside the tea capsule. The brewed tea soup flows out through the opening on the tea capsule cut by the water piercing knife 206, and the flowing tea soup flows through one opening of the second three-way valve 21 to the tea outlet of the brewing machine, and then flows out from the tea outlet of the brewing machine into the water cup below. After the tea is finished brewing, the third water pump 23 starts, and the water outlet connected to the second three-way valve 21 and the third water pump 23 is opened. The third water pump 23 sucks up the residual tea soup from the water outlet pipe 20 and the tea outlet of the brewing machine to avoid the phenomenon of tea soup dripping after the tea is finished brewing.

[0075] When the level detection element 29 detects that there is no water in the water tank 6, the second water pump 15 can be started to pump water from an external water source into the water tank 6 for water supply until the water level in the water tank 6 reaches the preset level height. Then the second water pump 15 can stop working, and the entire tea-making process ends.

[0076] The features and advantages of the brewing machine with a hydraulic system of the present invention are as follows: 1. The brewing machine with a hydraulic system, through the linkage assembly 9 and the hydraulic structure, can achieve pressure-resistant sealing and locking during capsule brewing, so that the brewing chamber 3 is always in a compressed and sealed state when brewing the capsule 28, so as to ensure the stable pressure resistance of the brewing chamber 3.

[0077] Second, in this brewing machine with a hydraulic system, the water tank 6 is used not only for water supply but also for connecting to an external water source to realize the function of external water supply. When the external water supply method is selected, the water tank 6 can be used as a transfer water tank. The second water pump 15 draws water from the external water source (such as external water from a large bottle) into the water tank 6 to realize the function of the brewing machine working permanently as long as the external water source is not short of water.

[0078] Third, in this brewing machine with a hydraulic system, the configuration of the third water pump 23 and the recovery chamber 22 can start the water suction after brewing (tea making) is completed, thus solving the problem of dripping after the tea is dispensed.

[0079] Fourth, this brewing machine with a hydraulic system can achieve fully automated control and is easy to operate. It can also be equipped with WiFi, enabling cloud connection and program control, thus improving the user experience.
