Description

Technical Field

[0001] This utility model relates to the technical field of household appliances, specifically to a novel coffee machine. Background Technology

[0002] For beginners, manually tamping coffee requires repeated practice to control the pressure, while coffee machines with built-in tamping functions simplify the process, allowing them to make decent coffee without professional skills. Therefore, these coffee machines with built-in tamping functions are widely used in everyday home use, small offices, or novice coffee shops.

[0003] Patent document CN120616312A discloses "a fully automatic coffee machine extraction device," which specifically includes: "When the product is turned on, the electronic program starts the grinder 500 to work, feeding the ground coffee powder 901 from the powder outlet 501 into the brewing cup 300. After the powder filling is completed, the first motor 100 drives the swing arm 200 and the brewing cup 300 to rotate towards the 'tamping / extraction' position." "The electronic program starts the extraction head 600 to work, performing 'tamping and extraction,' and continues to rotate after extraction is completed."

[0004] The brewing cup needs to move between different stations to complete the coffee grounds collection, tamping, and extraction processes, resulting in a relatively complex overall structure for the coffee machine. The equipment requires a significant amount of space, and there's a possibility of coffee grounds falling out from the grinder's outlet when the brewing cup moves to the extraction head. Furthermore, conventional tamping functions rely on a motor-driven tamping head, which suffers from structural complexity, high maintenance costs, and a higher susceptibility to bacterial growth in the motor and screw components, negatively impacting brewing quality and hygiene.

[0005] Therefore, further improvements are needed. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of coffee machine. The tamping unit, under the action of a hydraulic mechanism, is linked with the powder dispensing channel, ensuring that the powder dispensing channel does not interfere with the tamping action and preventing accidental powder spillage into the powder receiving chamber during the extraction process. Furthermore, after tamping, the tamping unit can supply water through the hot water chamber to further complete the extraction process, further simplifying the user's operation.

[0007] The purpose of this utility model is achieved as follows: A novel coffee machine includes a powder receiving compartment and a grinding mechanism. The powder receiving compartment has a powder receiving cavity, and a tamping part is provided above the powder receiving cavity inside the powder receiving compartment. A powder dispensing channel is provided between the powder receiving cavity and the powder dispensing part of the grinding mechanism. The powder dispensing end of the powder dispensing channel is connected and engaged with the powder receiving cavity. A hot water cavity for dispensing hot water is provided on the bottom inner side of the tamping part. The tamping part is connected to a hydraulic mechanism for driving it to move downward. A water supply mechanism for supplying water to the hot water cavity and the tamping part is provided on the outer side of the powder receiving compartment. The downward movement of the tamping part through the hydraulic mechanism can push the powder dispensing channel to move in the direction of exiting the powder receiving cavity. The powder dispensing channel moves in the direction of exiting the powder receiving cavity until the tamping part and the powder dispensing channel coincide in the horizontal direction, so that the powder dispensing end of the powder dispensing channel is blocked by the outer wall of the tamping part.

[0008] As a specific embodiment, the hydraulic mechanism includes a liquid delivery component, and the powder pressing part includes a powder pressing shell and a powder pressing head. A sealing part is provided around the liquid delivery component, and the sealing part is sealed to the inner wall of the powder pressing shell to form a hydraulic cavity between the liquid delivery component and the powder pressing head. The upper and lower ends of the liquid delivery component are respectively provided with a water inlet and a water outlet, and a water delivery channel is provided between the water inlet and the water outlet. Water is injected into the hydraulic cavity by the water outlet, which can cause the powder pressing head to move downward.

[0009] As a specific embodiment, the powder pressing shell is connected and fixed to the powder receiving chamber and the powder pressing head respectively. A spring is provided on the inner side of the powder pressing shell. The upper and lower sides of the spring are connected and cooperate with the upper inner end of the powder pressing shell and the upper side of the sealing part respectively. The sealing part and the inner wall of the powder pressing shell can slide and cooperate with each other. The powder pressing head drives the powder pressing shell to move downward, causing the spring to be deformed by pressure. The spring returning to its original position can drive the powder pressing head and the powder pressing shell to move upward.

[0010] As a specific embodiment, the sealing part is a sealing rubber ring, and the infusion fitting is provided with a limiting groove corresponding to the sealing part. The width of the sealing part matches the limiting groove, the cross-section of the sealing part is V-shaped, and the outer side of the sealing part presses against the inner side wall of the powder pressing shell.

[0011] As a specific embodiment, a water inlet chamber is provided in the powder receiving compartment at the position corresponding to the water inlet section. The infusion component is connected and fixed to the powder receiving compartment to ensure a sealed fit between the infusion component and the water inlet chamber. A water inlet connector is provided on the outside of the powder receiving compartment at the position corresponding to the water inlet chamber. The water inlet connector is connected to the water inlet section through the water inlet chamber.

[0012] As a specific embodiment, a hot water connector is provided on the outer side of the powder pressing part, and a hot water channel is provided inside the powder pressing part. The hot water chamber and the hot water connector are connected through the hot water channel, and the hot water connector is located on the vertically downward side of the water inlet connector.

[0013] As a specific solution, a heating component is provided between the water supply mechanism and the hot water chamber.

[0014] As a specific solution, a water outlet mesh is provided on the outer side of the powder pressing part corresponding to the bottom of the hot water chamber. The water outlet mesh is detachable from the powder pressing part and is connected and fixed to the powder pressing part by a locking member.

[0015] As a specific embodiment, the powder outlet channel is provided with an inner guide slope. The inner guide slope is inclined downward along the direction from the grinding mechanism to the powder receiving chamber. The powder pressing part moves downward and slides with the inner guide slope to make the powder outlet channel move in the direction of exiting the powder receiving chamber. The powder outlet part of the grinding mechanism protrudes outward, and the powder outlet channel is sleeved on the outside of the powder outlet part of the grinding mechanism and can move relative to each other along the axial direction.

[0016] As a specific embodiment, the outer side of the powder receiving chamber is provided with a movable component that is movably connected thereto. The powder outlet channel is set on the movable component. When the powder pressing part moves downward, it can push the powder outlet channel to move in the direction of exiting the powder receiving chamber and drive the movable component to move away from the powder receiving chamber.

[0017] The powder outlet channel and the powder outlet section of the grinding mechanism are both inclined downwards along the direction from the grinding mechanism to the powder receiving bin.

[0018] The guiding mechanism includes a limiting frame fixedly installed on the outside of the powder receiving chamber. The limiting frame is provided with a guide post. The guide post is inclined downward along the direction from the grinding mechanism to the powder receiving chamber. The outer side of the movable part is provided with a guide inclined hole sleeved on the outside of the guide post. The guide inclined hole is slidably engaged with the guide post. When the powder pressing part pushes the powder outlet channel downward to move in the direction of exiting the powder receiving chamber and drives the movable part to move away from the powder receiving chamber, the movable part moves upward along the length direction of the guide post through the guide inclined hole.

[0019] The outer side of the guide post is fitted with a return spring for pushing the movable part to move downward along the length of the guide post. The two ends of the return spring are connected and cooperated with the limit frame and the movable part, respectively. When the movable part moves downward along the length of the guide post, the powder outlet channel extends into the powder receiving cavity.

[0020] The beneficial effects of this utility model are: The powder pressing unit, linked to the powder outlet channel by a hydraulic mechanism, ensures that the powder outlet channel does not interfere with the powder pressing unit's pressing action and prevents accidental powder spillage into the powder receiving chamber during the pressing and extraction process. Furthermore, after pressing, the powder pressing unit can supply water through a hot water chamber to further complete the extraction process, further simplifying the user's operation.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] See Figures 1-10 This novel coffee machine includes a powder receiving compartment 1 and a grinding mechanism 2. The powder receiving compartment 1 has a powder receiving cavity 11. A tamping part 3 is provided above the powder receiving cavity 11 in the powder receiving compartment 1. A powder outlet channel 41 is provided between the powder receiving cavity 11 and the powder outlet part 21 of the grinding mechanism 2. The powder outlet end of the powder outlet channel 41 is connected and cooperates with the powder receiving cavity 11. A hot water cavity 31 for outputting hot water is provided on the bottom inner side of the tamping part 3. The tamping part 3 is connected to a hydraulic mechanism for driving its downward movement. The tamping part 3 is driven by the hydraulic mechanism, eliminating the need for additional drive motors and transmission components, simplifying the overall structure of the equipment, and making it cleaner and more hygienic.

[0033] The outside of the powder receiving chamber 1 is equipped with a water supply mechanism for supplying water to the hot water chamber 31 and the tamping unit 3. The tamping unit 3 moves downward through a hydraulic mechanism, which can push the powder outlet channel 41 to move in the direction of exiting the powder receiving chamber 11. The powder outlet channel 41 moves in the direction of exiting the powder receiving chamber 11 until the tamping unit 3 and the powder outlet channel 41 are aligned horizontally, so that the powder outlet end of the powder outlet channel 41 is blocked by the outer wall of the tamping unit 3. The coffee machine does not need to set up different stations for powder receiving, tamping and extraction, which simplifies the overall structure of the equipment, relatively reduces the space occupied by the equipment, and avoids the situation where the powder outlet channel 41 accidentally drops powder into the powder receiving chamber 11 during the tamping and extraction process.

[0034] The powder pressing unit 3 is linked with the powder outlet channel 41 under the action of the hydraulic mechanism, so that the powder outlet channel 41 will not affect the powder pressing unit 3 to perform the powder pressing action, and also avoids the situation where the powder outlet channel 41 accidentally drops powder into the powder receiving chamber 11 during the powder pressing and extraction process. At the same time, after the powder pressing is completed, the powder pressing unit 3 can supply water to the outside through the hot water chamber 31 to further complete the extraction process, which further simplifies the user's operation.

[0035] Furthermore, the hydraulic mechanism includes a liquid delivery component 5, and the powder pressing part 3 includes a powder pressing shell 32 and a powder pressing head 33. A sealing part 34 is provided around the liquid delivery component 5. The sealing part 34 is sealed and fitted with the inner wall of the powder pressing shell 32 and forms a hydraulic cavity 35 between the liquid delivery component 5 and the powder pressing head 33. The upper and lower ends of the liquid delivery component 5 are respectively provided with a water inlet 51 and a water outlet 56. A water delivery channel 53 is provided between the water inlet 51 and the water outlet 56. Water is injected into the hydraulic cavity 35 by the water outlet 56, which can make the powder pressing head 33 move downward. The liquid delivery component 5 can guide the liquid into the hydraulic cavity 35, thereby increasing the pressure on the powder pressing head 33. Under the action of water pressure, the powder pressing head 33 can move downward and complete the powder pressing action.

[0036] Furthermore, the powder pressing shell 32 is connected and fixed to the powder receiving chamber 1 and the powder pressing head 33 respectively. A spring member 61 is provided on the inner side of the powder pressing shell 32. The upper and lower sides of the spring member 61 are connected and cooperate with the upper inner side of the powder pressing shell 32 and the upper side of the sealing part 34 respectively. The sealing part 34 and the inner wall of the powder pressing shell 32 can slide and cooperate with each other. The powder pressing head 33 drives the powder pressing shell 32 to move downward, causing the spring member 61 to be deformed by pressure. The spring member 61 resets and drives the powder pressing head 33 and the powder pressing shell 32 to move upward. After the powder pressing is completed, the water outlet 56 stops applying water pressure to the hydraulic chamber 35. Under the action of the spring member 61, the powder pressing shell 32 drives the powder pressing head 33 to move upward, realizing the effect of the powder pressing head 33 and the powder pressing shell 32 automatically completing the reset action.

[0037] Furthermore, the sealing part 34 is a sealing ring, and the infusion component 5 is provided with a limiting groove corresponding to the sealing part 34. The width of the sealing part 34 matches the limiting groove, and the cross-section of the sealing part 34 is V-shaped. The outer side of the sealing part 34 presses against the inner wall of the powder pressing shell 32. When relative movement occurs between the sealing part 34 and the inner wall of the powder pressing shell 32, the sealing part 34 can better reduce the resistance between the two through deformation while maintaining good sealing performance.

[0038] Furthermore, a water inlet chamber 12 is provided inside the powder receiving chamber 1 at the position corresponding to the water inlet section 51. The infusion component 5 is connected and fixed to the powder receiving chamber 1 to ensure a sealed fit between the infusion component 5 and the water inlet chamber 12. A water inlet connector 13 is provided on the outside of the powder receiving chamber 1 at the position corresponding to the water inlet chamber 12. The water inlet connector 13 is connected to the water inlet section 51 through the water inlet chamber 12. The external water pipe only needs to be connected to the water inlet connector 13 to supply water to the water inlet section 51, without having to extend into the powder receiving chamber 1 to connect directly to the water inlet section 51, thus simplifying the installation structure.

[0039] Furthermore, a hot water connector 38 is provided on the outside of the powder pressing part 3, and a hot water channel 36 is provided inside the powder pressing part 3. The hot water chamber 31 is connected to the hot water connector 38 through the hot water channel 36, so the water pipe for supplying hot water does not need to extend into the powder pressing part 3 to connect with the hot water chamber 31, which simplifies the installation structure.

[0040] The hot water connector 38 is located on the vertically downward side of the water inlet connector 13, allowing users to complete the installation and connection of the external water pipe and the hot water supply pipe with the powder receiving chamber 1 and the powder pressing part 3 on the same side of the equipment, further simplifying the installation process.

[0041] Furthermore, a heating component is provided between the water supply mechanism and the hot water chamber 31. The water supply mechanism generates high-temperature hot water through the heating component and delivers it to the hot water chamber 31.

[0042] Furthermore, a water outlet mesh 37 is provided on the outer side of the powder pressing part 3 corresponding to the bottom of the hot water chamber 31. The water outlet mesh 37 is detachable from the powder pressing part 3 and is connected and fixed to the powder pressing part 3 by a locking member.

[0043] Furthermore, the powder outlet channel 41 is provided with an inner guide slope 411. The inner guide slope 411 is inclined downward along the direction from the grinding mechanism 2 to the powder receiving chamber 1. The powder pressing part 3 moves downward and slides in cooperation with the inner guide slope 411 to make the powder outlet channel 41 move in the direction of exiting the powder receiving chamber 11. The inner guide slope 411 can make the process of the powder pressing part 3 moving downward to push the powder outlet channel 41 smoother.

[0044] Furthermore, the powder outlet 21 of the grinding mechanism 2 protrudes outward, and the powder outlet channel 41 is sleeved on the outside of the powder outlet 21 of the grinding mechanism 2 and can move relative to each other along the axial direction. After the coffee powder leaves the powder outlet 21 of the grinding mechanism 2, it will enter the powder outlet channel 41. Compared with the design where the powder outlet channel 41 is set on the inside of the powder outlet 21, the chance of powder leakage at the connection between the powder outlet channel 41 and the powder outlet 21 can be reduced.

[0045] Furthermore, a movable part 4 is provided on the outside of the powder receiving chamber 1 and is movably connected thereto. The powder outlet channel 41 is provided on the movable part 4. When the powder pressing part 3 moves downward, it can push the powder outlet channel 41 to move in the direction of exiting the powder receiving chamber 11 and drive the movable part 4 to move away from the powder receiving chamber 1. Compared with the method of setting the powder outlet channel 41 on the inside of the powder outlet section 21 of the grinding mechanism 2, by setting the movable part 4, the worker can complete the connection and cooperation between the powder outlet channel 41 and the powder receiving chamber 11 and the powder outlet section 21 of the grinding mechanism 2 by installing the movable part 4 on the outside, which simplifies the overall assembly difficulty of the equipment.

[0046] Furthermore, both the powder outlet channel 41 and the powder outlet section 21 of the grinding mechanism 2 are inclined downwards along the direction from the grinding mechanism 2 to the powder receiving chamber 1, so that the coffee powder can flow into the powder receiving chamber 11 more easily under the action of gravity, reducing the chance of coffee powder remaining in the powder outlet channel 41.

[0047] Furthermore, the guiding mechanism includes a limiting frame 8 fixedly installed on the outside of the powder receiving chamber 1. The limiting frame 8 is provided with a guide post 81. The guide post 81 is inclined downward along the direction from the grinding mechanism 2 to the powder receiving chamber 1. The outer side of the movable part 4 is provided with a guide inclined hole 44 sleeved on the outer side of the guide post 81. The guide inclined hole 44 is slidably engaged with the guide post 81. When the powder pressing part 3 pushes the powder outlet channel 41 downward to move in the direction of exiting the powder receiving chamber 11 and drives the movable part 4 to move away from the powder receiving chamber 1, the movable part 4 moves upward along the length direction of the guide post 81 through the guide inclined hole 44. The connection structure between the guide post 81 and the guide inclined hole 44 is simple. The cooperation between the two can improve the stability of the movable part 4 when it drives the powder outlet channel 41 to move.

[0048] Furthermore, a return spring 9 is sleeved on the outer side of the guide column 81 to push the movable part 4 to move downward along the length direction of the guide column 81. The two ends of the return spring 9 are connected and cooperate with the limit frame 8 and the movable part 4, respectively. When the movable part 4 moves downward along the length direction of the guide column 81, the powder outlet channel 41 extends into the powder receiving cavity 11. That is, after the powder pressing part 3 returns to its original position, the movable part 4 can drive the powder outlet channel 41 to return to its original position and extend into the powder receiving cavity 11 through the return spring 9, thereby increasing the automation level of the equipment. Moreover, when the powder outlet end of the powder outlet channel 41 is blocked by the outer wall of the powder pressing part 3, the powder outlet end of the powder outlet channel 41 can be more closely attached to the outer wall of the powder pressing part 3 under the action of the return spring 5, thereby achieving a better sealing effect and further reducing the chance of accidental powder drop.

[0049] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
