Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of coffee machine field, in particular to a kind of integrated coffee beverage preparation system. BACKGROUND

[0002] In modern coffee culture, the popularity of coffee machines makes coffee making more convenient and efficient. However, most existing integrated coffee machines use automatic powder pressing.

[0003] CN117084554A discloses an automatic powder pressing device, a coffee machine and a control method thereof. The coffee machine includes a machine body, a powder cup assembly having a cavity for accommodating powder, a powder cup seat assembly arranged on the machine body for supporting the powder cup assembly, a powder pressing device capable of moving towards the powder cup seat assembly to apply pressure to the powder cup assembly, a first automatic sensing assembly electrically connected to the powder pressing device to start the powder pressing device to move towards the powder cup assembly, and a second automatic sensing assembly for detecting the pressing position of the powder pressing device to stop the pressing movement of the powder pressing device. By providing the first automatic sensing assembly to automatically start the powder pressing device to perform the powder pressing action towards the powder cup assembly, and the second automatic sensing assembly to limit the pressing position of the powder pressing device to stop its pressing movement, the automation and intelligence of the automatic powder pressing device are improved.

[0004] CN118592802A discloses a coffee machine and a working method thereof. The coffee machine is provided with a powder pressing mechanism, a coffee handle and a control assembly. The powder pressing mechanism is composed of a telescopic driving assembly, a pressing head and an elastic element. By driving the telescopic driving assembly and stretching the elastic element, the pressing effect of coffee powder can be effectively improved, which is beneficial to improving the taste of brewed coffee. On this basis, a first trigger switch and a second trigger switch are installed on the powder pressing mechanism to form the control assembly. When the amount of coffee powder in the coffee handle is sufficient, the first trigger switch can be used to automatically control the powder pressing operation of the powder pressing mechanism, effectively improving the convenience of use. When the amount of coffee powder in the coffee handle is insufficient or there is no coffee powder, the second trigger switch can be used to stop the powder pressing mechanism, realize empty pressing protection, avoid the situation that the pressing head is pressed empty in the coffee handle, and ensure the stability of use.

[0005] However, there are some limitations in the electric powder compression structure, which not only affect the extraction degree of coffee, but also limit the diversity and individual expression of coffee flavor. First of all, the electric powder compression structure often lacks interest and individualization. Since the electric powder compression structure relies on preset programs and automatic operation, users often cannot directly participate in the process of coffee powder compression, which reduces the interaction and experience of the coffee making process. Users cannot adjust the intensity and method of powder compression according to personal taste and preference, so that each cup of coffee tends to be the same, lacking individual expression. Secondly, the coffee machine with electric powder compression structure also has problems in energy consumption and equipment cost. The electric powder compression structure needs to consume electric energy to drive the powder compression action, which not only increases energy consumption, but also increases the operating cost of the coffee machine. In addition, the complexity of the electric powder compression structure leads to an increase in equipment cost, which may be a burden for small coffee shops and home users. More importantly, the process of powder compression has a direct impact on the extraction degree of coffee. Different coffee powder characteristics, such as particle size, moisture and freshness, have different requirements for powder compression. The intensity, uniformity and compaction of powder compression will affect the contact area of coffee powder and water, and thus affect the extraction efficiency and final flavor of coffee.

[0006] In view of the limitations of the prior art, it is necessary to develop a new type of coffee machine powder compression device that can provide a more personalized powder compression experience, reduce energy consumption and equipment cost, and meet the powder compression needs of different coffee powders to improve the extraction quality and flavor diversity of coffee.

The terms "first", "second" are only for the convenience of understanding, and have no other directional meaning, and cannot be regarded as a limitation of the present application.

[0060] As Figures 1-9As shown, the present embodiment provides an integrated coffee beverage preparation system, which comprises a coffee main machine 1 and a separable powder box module 2, and the coffee main machine 1 is provided with a placing position 3 for the powder box module 2. The coffee main machine 1 comprises a bean grinding module 4, a brewing module 5 and a powder compacting module 6. The bean grinding module 4 is used to grind coffee beans into coffee powder and deliver the coffee powder into the powder box module 2. The brewing module 5 is used to heat water and brew the coffee powder in the powder box module 2. The powder compacting module 6 compacts the coffee powder in the powder box module 2 before brewing and maintains a certain pressure during brewing to achieve extraction. The integrated design integrates the functions of bean grinding, brewing and powder compacting, greatly improving the efficiency of coffee preparation. At the same time, the modular and separable design makes cleaning and maintenance much simpler.

[0061] As shown, Figures 2-3 The coffee main machine 1 comprises a support 7, and the placing position 3 is arranged on the support 7. An opening is arranged on the outer side of the shell of the coffee main machine 1 to access the placing position 3, so that the powder box module 2 can enter the placing position 3 to cooperate with other modules to complete corresponding work, and can be removed from the placing position 3 to complete cleaning work.

[0062] As shown, Figures 2-4 The brewing module 5 comprises a water path, a heating module 8 and a powder compacting head 9. The powder compacting head 9 has two functions, including powder compacting and coffee powder flushing. The water path is in communication with the powder compacting head 9 through the heating module 8. The machine comprises a water tank 21, and a water pump 10 is usually arranged on the water path. The heating module 8 heats the water and controls the temperature at a certain temperature, and then the water is flushed through the powder compacting head 9 to the coffee powder in the powder box module 2, so as to extract coffee to form a coffee beverage.

[0063] As shown, Figures 2-6 The powder compacting module 6 comprises a powder compacting handle 11 and a lifting frame 12 driven by the powder compacting handle 11. The powder compacting head 9 is arranged at the lower end of the lifting frame 12. The powder compacting handle 11 is located outside the shell of the coffee main machine 1, so as to be manually operated by a user.

[0064] As shown, Figures 5-6 In the preferred technical solution, the powder compacting handle 11 drives the lifting frame 12 through a gear transmission assembly. Specifically, a vertical rack 13 is arranged on one side of the lifting frame 12. The powder compacting handle 11 is connected to a transmission gear 14 through a shaft portion, and the transmission gear 14 is engaged with the vertical rack 13. Rotating the powder compacting handle 11 around the shaft portion, the transmission gear 14 is engaged with the vertical rack 13 to drive, so as to drive the lifting frame 12 to move up and down, and then the powder compacting head 9 can be pressed down or away from the powder box module 2 on the placing position 3.

[0065] Preferably, as shown, Figures 5-9As shown, the lifting frame 12 has sliding blocks S on both sides, and vertical racks 13 are provided on the rear side of each sliding block S. The powder pressing handle 11 is connected to two parallel and spaced transmission gears 14 through the connecting shaft 15. The cooperation of the two sets of transmission gears 14 and the vertical racks 13 improves the lifting stability.

[0066] It's important to note that if the coffee grounds are not tamped, water may choose the path of least resistance during extraction, creating a channeling effect. This can lead to over-extraction of some coffee grounds and under-extraction of others, affecting the overall taste of the coffee. The tamping head 9 compresses the coffee grounds into a dense puck, filling every space in the container. The tamped grounds create resistance to water flow, slowing it down. This helps the flavor compounds in the coffee dissolve fully in the water, resulting in more even pressure during extraction and allowing water to penetrate the coffee grounds evenly, producing a rich, aromatic coffee. Manually tamping the coffee by rotating the tamper handle 11 increases the user's involvement and enjoyment in coffee preparation, encouraging active participation rather than simply waiting for the coffee to finish. Furthermore, the user can freely control the speed and force of rotating the handle, allowing them to adjust the density of the coffee grounds according to their personal taste and preferences, thus personalizing the coffee's flavor.

[0067] The rack and pinion mechanism allows for incremental adjustments to the tamping pressure, meaning users can more precisely control the compactness of the coffee grounds, thereby optimizing extraction. Different coffee grounds may require different compactions to achieve optimal extraction. By fine-tuning the pressure, users can optimize parameters for different types of coffee grounds to achieve their preferred extraction.

[0068] like Figure 9 As shown, a single tamping step is insufficient for the entire coffee preparation process. During the pouring of water over the coffee grounds, the impact of the water, as well as the surface tension and buoyancy of the grounds themselves, all compromise the density of the coffee powder. Therefore, in this embodiment, a locking module works in conjunction with the tamping module 6. The locking module automatically locks the tamping head 9 in place without any further operation after the tamping module 6 has tamped it into position, maintaining it in brewing mode and achieving pressure-controlled extraction of the coffee powder.

[0069] like Figure 5 , 6The locking mechanism includes a locking slot K provided on the support 7, a control key 16 and a locking pin 17 provided on the powder pressing handle 11. The control key 16 can control the locking pin 17 to enter or exit the locking slot K. When the locking pin 17 enters the locking slot K, the powder pressing handle 11 is locked and the powder pressing head 9 is in the brewing mode. When the locking pin 17 exits the locking slot K, the powder pressing handle 11 is released and the powder pressing head 9 can move. The locking mechanism helps to ensure that the contact between the coffee powder and the water remains consistent throughout the extraction process. This helps to avoid the situation where some coffee powder is over-extracted and becomes bitter, while other coffee powder is under-extracted and lacks flavor. The locking mechanism also helps to maintain the stability of the powder pressing state and avoid fluctuations in the extraction pressure, thereby improving the taste and aroma of the coffee.

[0070] In this embodiment, the locking mechanism uses a simple combination of the locking slot K, the control key 16 and the locking pin 17, without the need for complex mechanical structures or electronic components. This greatly simplifies the overall design of the coffee machine, reduces the production difficulty and the maintenance cost in the later stage. The simple mechanical structure means less material and fewer processing steps, thereby reducing the manufacturing cost and making the coffee machine more affordable and suitable for a wider consumer group. Due to the low cost, the coffee machine is competitive in terms of price and is more likely to be accepted by consumers, which helps to expand the market share.

[0071] In a specific preferred embodiment, as shown in Figure 5 、 8 The outer end of the locking pin 17 is provided with a first spring 18 to drive the locking pin 17 inwardly towards the locking slot K. The locking pin 17 is parallel to the shaft portion 15 and follows the rotation of the powder pressing handle 11. The locking pin 17 automatically enters the locking slot K under the action of the first spring 18. There are multiple locking slots K, and the continuous multiple locking slots K are distributed in the movement path of the locking pin 17 following the powder pressing handle 11. After the powder pressing operation of the powder pressing handle 11 is completed, the powder pressing head 9 is limited by the coffee powder in the powder box module 2, and the locking pin 17 enters one of the corresponding locking slots K. By setting the first spring 18 to drive the locking pin 17 to automatically enter the locking slot K, the height of the adjusted lifting frame 12 is automatically locked. The user only needs to operate the powder pressing handle 11 to complete the powder pressing and adjustment and locking of the height of the lifting frame 12, which improves the automation and convenience of the operation.

[0072] As shown in Figure 6 、 9 Each locking slot K is composed of a blocking surface e and an inclined sliding surface f. During the powder pressing rotation of the powder pressing handle 11, the locking pin 17 jumps on the continuous multiple inclined sliding surfaces f. The blocking surface e prevents the powder pressing handle 11 from rotating in the reverse direction to complete the self-locking.

[0073] As shown in Figures 5-9As shown, the locking mechanism includes a ratchet disc 19 fixed on the bracket 7 and a control key 16 and a lock pin 17 located on the powder pressing handle 11. The ratchet disc 19 is provided with one-way ratchet teeth n. A locking groove K is formed between adjacent one-way ratchet teeth n. Preferably, the blocking surface e is a vertical blocking surface e parallel to the lock pin 17, and the inclined sliding surface f is connected to the bottom of the previous blocking surface e and the top of the next blocking surface e.

[0074] In operation, the user only needs to rotate the powder pressing handle 11 forward to the desired position, and release the lock pin 17 of the powder pressing handle 11 to complete the self-locking. When reverse rotation is needed, only the control key 16 needs to be pressed to release the reverse locking and reset the powder pressing handle 11.

[0075] It should be noted that the combination of one-way ratchet teeth n and locking groove K, especially the design of vertical blocking surface e, ensures that the powder pressing handle 11 can be automatically locked after adjustment, prevents reverse rotation, and ensures the stability and accuracy of the height of the powder pressing head 9. The design of the lock pin 17 jumping on the continuous inclined sliding surface f allows the powder pressing handle 11 to move smoothly during forward adjustment, reducing jamming and friction and improving the smoothness of operation and user experience. The design of the inclined sliding surface f helps the lock pin 17 gradually enter the locking groove K during rotation, avoiding sudden impact and noise, making the adjustment process more stable.

[0076] The automatic locking mechanism reduces the risk of equipment damage caused by improper or accidental operation, improving the reliability of the equipment. The user only needs to rotate the powder pressing handle 11 forward to easily adjust the height of the powder pressing head 9, without the need for additional locking operations, simplifying the operation process.

[0077] As shown, Figures 5-9 The control key 16 includes an operating end 16a extending out of the outer end of the powder pressing handle 11 and an acting end 16b located inside the powder pressing handle 11. The acting end 16b includes an inclined acting surface m located on the outside. The lock pin 17 extends outwardly to the ratchet disc 19 and includes a pin hole g. The front end of the acting end 16b is inserted into the pin hole g. The inner wall of the pin hole g of the lock pin 17 cooperates with the inclined acting surface m to make the lock pin 17 slide along the inclined acting surface m. The outer end of the lock pin 17 is provided with a first spring 18, and the elastic force of the first spring 18 makes the lock pin 17 close to the one-way ratchet teeth n. The front end of the control key 16 is provided with a second spring 20, and the elastic force of the second spring 20 makes the inclined acting surface m disengage from the pin hole g. The control key 16 can control the lock pin 17 to enter or exit the one-way ratchet teeth n. The lock pin 17 cooperates with the one-way ratchet teeth n and rotates along the one-way ratchet teeth n when the powder pressing handle 11 rotates forward, and completes self-locking when the powder pressing handle 11 rotates reversely.

[0078] The ingenious design of the control key 16 and the locking pin 17 achieves a high degree of operational linkage. The front end 16b of the control key 16 is inserted into the pin hole g of the locking pin 17. Through the cooperation between the inclined action surface m and the inner wall of the locking pin 17, even a slight movement of the control key 16 can cause the locking pin 17 to slide along the inclined action surface m, thereby realizing the operation of the locking pin 17 entering or exiting the one-way ratchet n. This linkage mechanism ensures that the user can control the state of the locking pin 17 simultaneously when operating the powder pressing handle 11, without the need for additional operation steps, thus improving the continuity and efficiency of operation.

[0079] By setting a first spring 18 and a second spring 20, which are respectively used to move the locking pin 17 close to the one-way ratchet n and the inclined action surface m of the control key 16 away from the pin hole g, the automatic return of the locking pin 17 and the reset function of the control key 16 are achieved. Users can easily engage or disengage the locking pin 17 by simply pressing or releasing the control key 16, eliminating the need for strenuous or complicated operations and greatly improving operational convenience. Furthermore, the design of the control key 16 and the locking pin 17 allows users to complete the entire adjustment process with one hand, further enhancing operational ease.

[0080] Preferably, such as Figures 6-9 As shown, the rear end of the powder pressing handle 11 has a sloping surface j that slopes from top to bottom and from front to back. This sloping surface j creates a notch above the operating part of the powder pressing handle 11, and the operating end 16a of the control key 16 extends out from the sloping surface j and is located at this notch. This technical solution achieves the linkage between the rotation of the powder pressing handle 11 and the operation of the control key 16 by designing the sloping surface j at the rear end of the powder pressing handle 11 and the position of the control key 16.

[0081] When the powder tamping handle 11 is rotated forward, the control button 16 is obscured by the beveled surface j because the fingertip is located on the lower surface of the handle 11, making it difficult to touch. This effectively hides and protects the control button 16 when not in use, thus preventing accidental unlocking of the locking pin 17. When the powder tamping handle 11 is rotated backward, the thumb can naturally press the control button 16 located at the notch. Without changing hand posture or adding extra steps, the locking pin 17 can be unlocked and the handle rotated backward simultaneously with a single force. This design not only simplifies the operation process and improves convenience, but also enhances the continuity and efficiency of operation.

[0082] Preferably, such as Figures 8-9 As shown, a buffer mechanism is provided between the tamping head 9 and the lifting frame 12. After the tamping head 9 contacts the coffee powder in the powder container module 2, the tamping head 9 floats flexibly relative to the lifting frame 12 through the buffer mechanism. The lifting frame 12 is equipped with a sensing component. After the sensing component detects that the tamping head 9 has floated to the rated position, the brewing module 5 is turned on.

[0083] The buffering mechanism is a flexible spring t between the powder pressing head 9 and the lifting frame 12.
