Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a coffee grinding and brewing mechanism for a coffee machine.

[0004] To achieve the above objectives, this utility model provides a coffee grinding and brewing mechanism for a coffee machine, comprising a base, a grinding assembly, a heat preservation assembly, and a control assembly detachably installed within the base; the grinding assembly and the heat preservation assembly are electrically connected to the control assembly. The grinding assembly includes a grinding hopper, a grinding blade assembly disposed within the grinding hopper, a grinding drive unit for driving the grinding blade assembly, and a liquid storage chamber disposed on the side of the grinding hopper, which communicates with the grinding hopper. The grinding hopper is equipped with a filter screen. The grinding drive unit drives the grinding blade assembly to grind the coffee beans placed in the grinding hopper into coffee powder. Water flows into the grinding hopper through the water inlet and brews with the coffee powder. The brewed coffee liquid is filtered through the filter screen of the grinding hopper and flows into the liquid storage chamber. The coffee liquid in the liquid storage chamber is used to supply coffee pots to the outside. The heat preservation assembly is used to heat and keep the coffee pots warm.

[0005] By integrating grinding, brewing, and heat preservation functions into one unit, the entire coffee-to-beverage process is automated, improving production efficiency and convenience. Users place coffee beans in the grinding chamber, and the control unit activates the grinding drive to grind the beans into powder. Simultaneously, water flows in through the inlet and mixes with the coffee powder for brewing. The brewed coffee liquid is filtered through a filter to remove impurities before flowing into the storage chamber and finally into the coffee pot placed on the heat preservation unit. The heat preservation unit then heats and keeps the coffee pot warm, ensuring the coffee's taste and temperature are optimal. The entire operation is simple and quick, enhancing the user experience.

[0006] The coffee grinding and brewing mechanism also includes a detachable visible water tank mounted on the base, a water guiding component electrically connected to the control component, and a heating pipe. The bottom of the visible water tank is connected to the water guiding component, one end of the heating pipe is connected to the water guiding component, and the other end of the heating pipe away from the water guiding component is connected to the coffee grinding box. The water in the visible water tank flows into the heating pipe through the water guiding component and is heated before flowing into the coffee grinding box. The heated water brews the coffee powder in the coffee grinding box.

[0007] By integrating a visible water tank and an intelligent water guiding and heating system, the convenience and quality of coffee making are significantly improved. Users simply place coffee beans in the grinder compartment, add water to the visible water tank, and once the control unit is activated, the grinder assembly grinds the coffee beans. Simultaneously, the water guiding component directs the water in the visible water tank into the heating pipe for heating. The hot water then flows into the grinder compartment to mix with the coffee grounds and brew. After filtering, the mixture flows into the coffee pot, where the temperature is maintained by the insulation component. Throughout the process, users can visually monitor the water level through the visible water tank, and intelligent temperature control ensures the water temperature is suitable, allowing them to easily enjoy high-quality coffee.

[0008] The heat preservation component includes a heating plate mounted on a base, a control component that adjusts the temperature of the heating plate, and a heat dissipation channel located at the bottom of the base below the heating plate.

[0009] The heating plate in the insulation unit adjusts its temperature according to the instructions from the control unit to ensure the coffee in the pot maintains a suitable taste. Meanwhile, the heat dissipation channels at the bottom of the base effectively dissipate the heat generated by the heating plate, preventing the machine from overheating and ensuring stable operation.

[0010] The coffee grinder assembly includes a drive shaft, a blade rotatably mounted on the drive shaft, a through hole at the bottom of the grinder box, a first sealing ring housed in the through hole, and the free end of the drive shaft protruding out of the through hole and connected to the output end of the grinder drive. The first sealing ring is used to prevent coffee powder in the grinder box from leaking from the through hole to the side of the grinder drive.

[0011] The grinder drive unit drives the blades to rotate at high speed via a drive shaft, precisely grinding coffee beans into a fine and uniform coffee powder. Simultaneously, the first sealing ring fits tightly around the through-hole at the bottom of the grinder hopper, effectively preventing coffee powder from leaking through the through-hole to the grinder drive unit, thus avoiding internal contamination and malfunctions. This design not only ensures the quality and taste of the coffee but also extends the lifespan of the coffee machine, providing users with a more stable and reliable coffee-making experience.

[0012] The coffee grinding assembly also includes a lid assembly disposed above the coffee grinding chamber. The lid assembly includes a first housing mounted above the coffee grinding chamber and a first cover covering the first housing. The first housing is provided with a flow guide groove, and the bottom surface of the flow guide groove is provided with multiple sets of round holes. The round holes are disposed above the coffee grinding chamber. A one-way valve is provided at the end of the flow guide groove away from the round holes. The coffee grinding chamber is provided with a pipe channel. The heating pipe is connected to the one-way valve through the pipe channel. The hot water from the heating pipe flows to the flow guide groove through the one-way valve. The hot water seeps into the coffee grinding chamber through the round holes of the flow guide groove to brew the coffee powder.

[0013] The coffee grinder assembly includes a first housing and a first lid. The first housing features a flow channel and multiple sets of round holes, allowing hot water from the heating element to enter the flow channel via a one-way valve and then evenly and delicately seep into the coffee grounds inside the grinder, achieving efficient brewing. This design not only ensures full contact between the hot water and the coffee grounds, improving brewing efficiency, but also effectively prevents backflow through the one-way valve, ensuring safe operation of the machine. Simultaneously, the lid assembly's sealing performance is further enhanced, preventing the loss of steam and aroma during brewing, providing users with a richer, more aromatic coffee experience.

[0014] The bottom of the liquid storage chamber is also provided with a water outlet assembly. The bottom of the liquid storage chamber is provided with a water outlet hole. The water outlet assembly includes a movable water outlet valve and a leak-proof valve spring for driving the water outlet valve to reset. One end of the water outlet valve is installed in the water outlet hole, and the other end of the water outlet valve is provided with a conical guide protrusion, which forms a line contact seal with the V-shaped groove of the coffee pot water inlet.

[0015] The design of the leak-proof valve spring in conjunction with the water outlet valve ensures a good seal in the liquid storage chamber when not dispensing water, preventing coffee leakage and avoiding coffee waste and contamination of the surrounding area. The line contact seal formed by the tapered guide protrusion and the V-shaped groove at the coffee pot inlet allows coffee to flow precisely into the coffee pot, reducing splashing and improving the user experience.

[0016] The first housing is equipped with a Hall sensor. The Hall sensor is used to sense when the first cover is closed on the first housing and transmits the signal back to the control component. Only then can the control component start the grinding component, the water guiding component, or the heat preservation component.

[0017] By integrating a Hall effect sensor, a dual guarantee of safe start-up and intelligent monitoring is achieved, further enhancing the user experience and safety. When the first lid is correctly closed onto the first housing, the Hall effect sensor instantly senses and transmits a signal to the control component. Only after receiving the signal does the control component allow the start of the grinding component, water guiding component, or heat preservation component. This design effectively prevents accidental start-up due to improper installation or closure of components, ensuring user safety and stable operation of the coffee machine. At the same time, the accurate sensing of the Hall effect sensor also ensures the continuity and efficiency of the coffee brewing process, bringing users a more reassuring and convenient coffee brewing experience.

[0018] The grinding drive includes a bracket mounted on a base, a motor drive installed inside the bracket, and a shock-absorbing device at the bottom of the bracket.

[0019] The motor drive unit is mounted within a bracket on the base, driving the grinding blade assembly to precisely grind coffee beans. The shock-absorbing device at the bottom of the bracket effectively absorbs vibrations generated during motor operation, reducing noise and wear, and extending the coffee machine's lifespan. This design not only ensures the fineness and uniformity of the coffee powder grind but also provides users with a quieter and more stable coffee-making experience.

[0020] The grinding chamber is equipped with a filter cartridge, through which the brewed coffee liquid is filtered and flows into the storage chamber.

[0021] Users place coffee beans into the filter cartridge within the grinder. Water from the visible water tank is heated through a water guide assembly and heating pipes before flowing into the grinder, where it mixes with the coffee grounds for brewing. The grinder drive, including a support on the base, a motor drive within the support, and a shock-absorbing device, drives the grinder blades to precisely grind the coffee beans, while the filter cartridge effectively filters out impurities and particles from the brewed coffee, ensuring the purity and flavor of the coffee.

[0022] The water guiding assembly includes a movable stop valve and a spring for resetting the stop valve. The stop valve is equipped with a steel ball, and the bottom outlet of the visible water tank is equipped with a second sealing ring. When the visible water tank is removed, the second sealing ring presses against the outlet to prevent water from flowing out of the visible water tank. When the visible water tank is placed on the water guiding assembly, the stop valve of the visible water tank moves upward, the steel ball abuts against the second sealing ring, and the second sealing ring disengages from the outlet of the visible water tank, allowing water to flow from the outlet of the visible water tank into the heating pipe.

[0023] When the visible water tank is removed, the second sealing ring tightly presses against the outlet, effectively preventing water from leaking out and ensuring the machine's safety and cleanliness. When the visible water tank is correctly placed on the water guiding assembly, the stop valve moves upward under pressure, and the steel ball contacts and pushes open the sealing ring, disengaging the outlet from it. This allows water to flow smoothly from the visible water tank into the heating pipes for subsequent heating and brewing. This design not only simplifies the coffee-making process but also provides users with a safer and more efficient coffee brewing experience through the dual protection of intelligent water guiding and secure sealing.

[0024] The beneficial effects of this utility model: The coffee machine's grinding and brewing mechanism integrates multiple functions such as grinding, brewing, heat preservation, intelligent water guiding, and shockproof safety into one unit, achieving fully automated and efficient processing of coffee from beans to beverage. Its principle lies in using a motor-driven grinding blade assembly to precisely grind coffee beans, while the water guiding assembly intelligently guides heated water from the visible water tank into the grinding chamber to mix with the coffee powder for brewing. The brewed coffee liquid is then filtered and flows into the storage chamber before finally being poured into the insulated coffee pot. This design not only significantly improves the convenience and quality of coffee making but also ensures stable operation of the coffee machine and a worry-free user experience through multiple safety safeguards and intelligent monitoring, bringing users a more efficient, pure, and aromatic coffee enjoyment.
