Description

Technical Field

[0001] This utility model relates to a brewing head for a coffee machine. Background Technology

[0002] The brewing head of a coffee machine is one of the most important components affecting coffee extraction. Its main function is to evenly distribute heated water to the coffee grounds for full extraction. However, in current coffee machine brewing head designs, the water outlet is usually only located on the brewing head itself. Hot water flows directly to the shower head through the outlet. Due to gravity and inertia, the water tends to concentrate in a localized area of ​​the shower head, causing only some of the drainage holes to function. Other drainage holes, lacking sufficient water supply, fail to drain evenly, resulting in uneven water distribution to the coffee grounds and consequently affecting extraction. This uneven water distribution can easily lead to over-extraction in some areas and under-extraction in others, ultimately impacting the flavor and strength of the coffee.

[0003] In existing technologies, coffee machine brewing heads are generally made of either all-plastic or all-aluminum materials. Using all-plastic brewing heads will result in coffee with a plastic taste, while all-aluminum brewing heads will oxidize and affect their appearance after long-term use. Utility Model Content

[0004] The purpose of this invention is to provide a brewing head for a coffee machine that evenly distributes water to multiple drainage holes on the shower head, achieving more uniform water flow coverage, improving the uniform wetting effect of coffee powder, and thus improving the extraction quality of coffee.

[0005] The purpose of this utility model is achieved as follows:

[0006] A brewing head for a coffee machine includes a brewing head body and a shower head, and also includes a water distribution base, wherein the brewing head body is provided with a water outlet;

[0007] The water distribution seat has a water trough, and the bottom of the water distribution seat has drain outlets spaced apart from the water trough;

[0008] The water distribution seat is set on the brewing head body, and the water outlet is connected to the water tank;

[0009] The shower head blades are spaced apart with drain holes, and the shower head blades are mounted on the main body of the rinsing head and located below the water distribution base.

[0010] Uniform water distribution for improved brewing results: This invention adds a water distribution seat between the brewing head and the shower head, using a water tank structure to distribute the water flow evenly to multiple drain outlets before it is discharged through the shower head. This avoids water concentrating in a localized area of ​​the shower head, ensuring that all drain outlets function effectively, improving the uniform wetting of coffee grounds, and enhancing the extraction quality of coffee.

[0011] Traditional brewing head designs often result in over-extraction in some areas and under-extraction in others. However, this invention, through a ring-shaped water tank and a water distribution structure, allows hot water to cover a wider area of ​​coffee grounds, avoiding localized over-extraction or under-extraction, thus improving brewing stability and the consistency of coffee taste.

[0012] The water distribution seat design of this invention ensures that the water flow enters the shower blades after being properly distributed, so that the multiple drainage holes on the shower blades can be fully utilized, reducing the problem of some drainage holes being idle, improving the water flow rate, and optimizing the extraction process.

[0013] This brewing head design is compatible with different types of coffee machines, and its compact structure and low manufacturing cost will not significantly increase production costs. At the same time, it improves the brewing effect while maintaining the reliability and durability of the product.

[0014] The objective of this utility model can also be achieved by the following technical measures:

[0015] Furthermore, the water tank is an annular water tank.

[0016] The ring-shaped water tank design ensures that the water flow is evenly distributed along the entire ring channel and then discharged through the drain outlet at the bottom of the water distribution base. This ensures that each drain hole on the shower blade receives a uniform water flow, improving the overall saturation of the coffee grounds and optimizing the extraction effect.

[0017] Traditional straight-through water flow can easily cause water to concentrate on one side, while an annular water tank can effectively disperse the water flow and prevent over- or under-extraction on one side.

[0018] Even water flow distribution can avoid problems such as excessive water flow and strong impact in local areas, ensuring that the coffee grounds are evenly watered, reducing the phenomenon of grounds collapsing, and improving extraction stability and product quality.

[0019] The circular water trough design ensures that the water flow is distributed in multiple directions, preventing water blockage or uneven drainage. This allows all the drain holes on the showerhead to drain fully, improving water flow rate and further optimizing brewing efficiency.

[0020] This circular water tank design is suitable for coffee machines of different sizes and types without significantly increasing production costs. It maintains a compact structure while optimizing brewing results, thereby improving the product's market adaptability and competitiveness.

[0021] Furthermore, the water distribution seat is an annular water distribution seat, and the annular water distribution seat has the annular water groove.

[0022] By adopting a ring-shaped water distribution seat structure with a ring-shaped water groove on it, the water flow is evenly distributed along the ring channel before entering the shower blade, and then flows out through the drain outlet at the bottom of the water distribution seat to the shower blade. This avoids the water flow from concentrating in a local area, and ensures that the drainage holes of the entire shower blade can drain water evenly, improving the saturation of coffee grounds and optimizing the extraction effect.

[0023] Traditional straight-through water flow designs can easily lead to over-extraction in some areas and under-extraction in others. In contrast, the ring-shaped water distribution seat ensures that water flows evenly to the shower head from multiple directions, making the coffee grounds more evenly watered, avoiding uneven extraction concentration, and improving brewing stability and consistency of coffee flavor.

[0024] Because the annular water distribution seat can effectively disperse the water flow and reduce the concentrated impact of the water flow, the water flow can more gently wet the coffee grounds, reduce the collapse of the coffee grounds caused by excessive local rinsing, ensure that the coffee grounds are subjected to balanced force, and improve the quality of coffee extraction.

[0025] The design of the annular water channel and multiple drain outlets in the ring-shaped water distribution base allows water to flow more evenly through each drain hole of the shower head, improving drainage efficiency and avoiding the problem of some drain holes being empty, thereby enhancing the brewing effect of the coffee machine.

[0026] The ring-shaped water distribution base design makes the entire brewing head structure more reasonable and compact, suitable for different types and sizes of coffee machines, without significantly increasing manufacturing costs, while ensuring product reliability and durability, and enhancing market competitiveness.

[0027] Furthermore, the diameter of the annular water distribution seat is smaller than the diameter of the shower head.

[0028] Because the diameter of the annular water distribution seat is smaller than that of the shower head, the water flow, after being divided by the annular groove of the water distribution seat, can be more evenly distributed across the entire shower head, rather than being confined to the central area of ​​the shower head. This allows the water flow to cover a larger area of ​​the shower head, improving the utilization rate of all drain holes, ensuring even water distribution to the coffee grounds, and improving brewing uniformity.

[0029] Traditional water flow designs tend to concentrate water flow in a localized area of ​​the shower head. This design, however, uses a ring-shaped water distribution base with a diameter smaller than the shower head, allowing the water flow to be more fully diffused before entering the shower head. This avoids the problem of water flow bias in one direction, resulting in a more balanced brewing process and improved consistency in coffee flavor.

[0030] Furthermore, there are at least three drain outlets.

[0031] By placing three drain outlets at intervals at the bottom of the ring-shaped water distribution base, water can be discharged evenly from multiple directions, rather than flowing out from a single point. This effectively disperses the impact force of the water flow, reduces the problem of excessive rinsing in certain areas, and allows the coffee grounds to be watered more evenly, further optimizing the extraction effect.

[0032] Because the three drain outlets are reasonably distributed, the water flow will not create an excessively strong scouring effect in any one area, thereby reducing the impact on the coffee grounds, reducing the collapse of the coffee grounds, and improving the consistency of extraction and the stability of coffee flavor.

[0033] The use of a smaller diameter annular water distribution base, combined with an optimized design of three drain outlets, not only ensures good brewing results but also maintains the compactness of the brewing head structure, making it compatible with different sizes and types of coffee machines, thus enhancing the product's versatility and market competitiveness.

[0034] Furthermore, it also includes a sealing ring and a brewing base. The sealing ring is disposed on the brewing head body and located outside the shower blade. The brewing base has a coffee outlet. The brewing base and the brewing head body are locked together. The shower blade is placed inside the brewing base. The sealing ring seals the gap between the brewing head body and the brewing base.

[0035] By setting a sealing ring between the brewing head body and the brewing base, the gap between the two is effectively filled, preventing water from leaking out of the joint during the brewing process, improving the sealing performance of the brewing system, and avoiding unstable coffee extraction or equipment failure due to leakage.

[0036] The sealing ring not only prevents water leakage, but also ensures that the water pressure inside the brewing head remains stable, preventing pressure loss and allowing hot water to pass through the shower head evenly and stably, thereby improving the uniformity of water distribution to the coffee grounds and enhancing the extraction efficiency and flavor stability of the coffee.

[0037] Because the brewing base and brewing head body adopt a snap-fit ​​structure, combined with the sealing effect of the sealing ring, the assembly between the components is more tight and stable, reducing the problem of loosening or misalignment caused by long-term use, and improving the durability and long-term stability of the brewing head.

[0038] The brewing base is equipped with a coffee outlet that works in conjunction with the brewing head and shower head to ensure a smooth flow of coffee, preventing coffee residue or dripping caused by unstable water flow or leakage, thus improving the quality and cleanliness of the finished product.

[0039] The use of a sealing ring and a clamping structure makes the assembly of the brewing head assembly more secure, suitable for different types of coffee machines, and does not affect the ease of disassembly and maintenance, thus improving the product's versatility and market adaptability.

[0040] Furthermore, the brewing head body is provided with a concave cavity, and water guiding grooves are spaced apart along the circumference of the brewing head body in the concave cavity. The water guiding grooves are connected to the concave cavity, and the water outlet is provided inside the concave cavity.

[0041] The concave structure can form an initial water flow accumulation zone, which can effectively collect and buffer the incoming hot water, providing stable starting conditions for subsequent uniform flow distribution, thereby improving the overall balance of water flow distribution and improving the wetting effect of coffee powder.

[0042] The water guide channel, arranged along the circumference of the concave cavity, can evenly guide the water flow from the cavity to various directions, avoiding water flow concentration in a single area and ensuring that the water flow is transmitted along different paths, thereby achieving a more uniform water flow distribution and optimizing the balance of coffee extraction.

[0043] The interconnected design of the water guide channel and the concave cavity allows the water flow in the concave cavity to smoothly enter each guide channel, ensuring that the water flow can be quickly transmitted to each drainage point after initial distribution, further improving the accuracy and uniformity of the overall water flow control.

[0044] The outlet is located inside the concave cavity, so that the water flow has a good pre-dispersion effect after being regulated by the concave cavity, thus laying the foundation for the uniform distribution of the water flow through the water guide channel and the water distribution seat, and ensuring the balanced distribution of the water flow in the initial state.

[0045] Furthermore, the brewing head body includes a shell and a brewing component, the brewing component is disposed in the inner cavity of the shell, and the brewing component has the concave cavity, the water guiding groove and the water outlet.

[0046] The combined structure of the outer shell and brewing components allows for independent optimization of the functions of each component. This facilitates the selection of materials suitable for different working conditions, as well as subsequent assembly, maintenance, and replacement, thereby improving overall durability and brewing performance.

[0047] Furthermore, the water distribution seat is disposed on the concave cavity.

[0048] The water distribution seat is located on the concave cavity, which allows the water flow that has been initially regulated by the concave cavity to be further evenly distributed on the water distribution seat. The water flow is then evenly discharged onto the shower head through the drain outlet, ensuring a balanced water flow distribution throughout the shower area and improving the uniformity of the rinsing.

[0049] Furthermore, the outer shell is made of aluminum, the brewing component is made of stainless steel, and both the brewing component and the water distribution base are within the projection range of the shower head.

[0050] The aluminum casing reduces the overall weight, while the stainless steel material offers high strength and excellent corrosion resistance, making it suitable for high-temperature and high-pressure brewing environments. It can operate stably for a long time, ensuring that the brewing components maintain stable performance during repeated use, thereby guaranteeing the quality of coffee extraction.

[0051] By arranging both the brewing component and the water distribution base within the projection area of ​​the shower head, and because the area of ​​the shower head is larger than that of the brewing component and the water distribution base, the water flow forms a balanced coverage across the entire shower head, rather than being confined to the central area. This helps to achieve a uniform distribution of water flow throughout the entire area, preventing excessive concentration of water flow in certain areas, thereby significantly improving the uniformity of water distribution to the coffee grounds and the extraction effect.

[0052] The beneficial effects of this utility model are as follows:

[0053] This invention, through a ring-shaped water tank and a water distribution structure, allows hot water to cover a wider area of ​​coffee powder, avoiding localized over-extraction or insufficient brewing, thereby improving brewing stability and the consistency of coffee taste.

[0054] The water distribution seat design of this utility model ensures that the water flow enters the shower blade after being reasonably distributed, so that the multiple drainage holes on the shower blade can be fully utilized, reducing the problem of some drainage holes being idle, improving the water flow rate, and optimizing the extraction process.

[0055] In this invention, because the diameter of the annular water distribution seat is smaller than the diameter of the shower head, the water flow, after being divided by the annular water groove of the water distribution seat, can be more evenly distributed to the entire shower head, rather than being confined to the central area of ​​the shower head. This allows the water flow to cover a larger area of ​​the shower head, improves the utilization rate of all drain holes, ensures even water distribution to the coffee grounds, and improves brewing uniformity.

[0056] This invention utilizes three drain outlets spaced at the bottom of the annular water distribution base to allow water to flow evenly from multiple directions, rather than from a single concentrated point. This effectively disperses the impact force of the water flow, reduces localized over-rinsing, and ensures more even water distribution to the coffee grounds, further optimizing the extraction process.

[0057] In this invention, the synergistic effect of the annular water tank and the annular water distribution seat enables the water flow to be dispersed in layers from the water outlet to the shower head, ensuring that the water flow is fully diverted before entering the coffee grounds, thereby achieving a more uniform brewing effect and significantly improving the extraction quality of coffee.

[0058] In this invention, when water flows out of the outlet, a portion of the water flows rapidly along the water guide groove to the edge of the shower head and directly enters the shower head. This path ensures that the water flow can quickly reach the outer area of ​​the shower head. Simultaneously, another portion of the water enters the annular water channel within the concave cavity and annular water distribution seat. Since the diameter of the water distribution seat is smaller than the diameter of the shower head, this portion of water, after being evenly diffused within the annular water channel, is discharged through three evenly arranged drain outlets and enters the shower head. The discharged water is further dispersed at the spaced drain holes on the shower head. Because the area of ​​the shower head is larger than the area of ​​the water distribution seat and the brewing components, the water flow forms a balanced coverage across the entire shower head, not confined to the central area. The two water flows complement each other on the shower head, jointly ensuring that the water flow evenly wets the coffee grounds, improving the overall brewing effect. Attached Figure Description

[0067] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0068] Example 1, combined with Figures 1 to 5 As shown, a coffee machine brewing head includes a brewing head body 1 and a shower blade 2, and also includes a water distribution base 3. The brewing head body 1 is provided with a water outlet 11.

[0069] The water distribution seat 3 has a water trough 4, and the bottom of the water distribution seat 3 has a drain outlet 5 spaced apart from the water trough 4.

[0070] The water distribution seat 3 is set on the brewing head body 1, and the water outlet 11 is connected to the water tank 4;

[0071] The shower head 2 has drainage holes 21 spaced apart, and the shower head 2 is disposed on the rinsing head body 1 and located below the water distribution base 3.

[0072] Furthermore, the water tank 4 is an annular water tank.

[0073] Furthermore, the water distribution seat 3 is an annular water distribution seat, and the annular water distribution seat has the annular water groove.

[0074] Furthermore, the diameter of the annular water distribution seat is smaller than the diameter of the shower head 2.

[0075] Furthermore, there are three drain outlets 5.

[0076] Furthermore, it also includes a sealing ring 6 and a brewing base 7. The sealing ring 6 is disposed on the brewing head body 1 and located outside the shower blade 2. The brewing base 7 has a coffee outlet 71. The brewing base 7 and the brewing head body 1 are locked together. The shower blade 2 is placed inside the brewing base 7. The sealing ring 6 seals the gap between the brewing head body 1 and the brewing base 7.

[0077] When heated water flows out of the outlet 11 inside the brewing head body 1, it first enters the annular water tank 4 located in the annular water distribution seat 3. Because the water tank has a closed annular structure, the water flow is forced to spread evenly along the entire annular path after entering, avoiding direct concentration in a fixed area.

[0078] The diameter of the annular water distribution base 3 is smaller than that of the shower head 2. This design ensures that the water flow, which is evenly distributed within the water tank 4, is discharged evenly through three spaced drain outlets 5 when it reaches the bottom of the water distribution base. Multiple drain outlets are located at the bottom of the water distribution base, each handling a portion of the water flow, thus preventing the water flow from concentrating and discharging only towards the center.

[0079] The discharged water flow is further dispersed through the drain hole 21 below the shower head 2. Since the area of ​​the shower head 2 is larger than that of the annular water distribution seat 3, the water flow, after being sprayed from the drain outlet 5, forms a uniform coverage on the entire surface of the shower head 2. This not only ensures that all areas of the shower head 2 are affected by the water flow, but also ensures that the coffee grounds are evenly moistened, avoiding localized over-wetting or dryness.

[0080] Through the above process, the synergistic effect of the annular water tank and the annular water distribution seat achieves layered dispersion of water flow from the outlet to the shower head, ensuring that the water flow is fully diverted before entering the coffee grounds, thereby achieving a more uniform brewing effect and significantly improving the extraction quality of coffee.

[0081] Example 2, combined with Figures 6 to 8As shown, a coffee machine brewing head includes a brewing head body 1 and a shower blade 2, and also includes a water distribution base 3. The brewing head body 1 is provided with a water outlet 11.

[0082] The water distribution seat 3 has a water trough 4, and the bottom of the water distribution seat 3 has a drain outlet 5 spaced apart from the water trough 4.

[0083] The water distribution seat 3 is set on the brewing head body 1, and the water outlet 11 is connected to the water tank 4;

[0084] The shower head 2 has drainage holes 21 spaced apart, and the shower head 2 is disposed on the rinsing head body 1 and located below the water distribution base 3.

[0085] Furthermore, the water tank 4 is an annular water tank.

[0086] Furthermore, the water distribution seat 3 is an annular water distribution seat, and the annular water distribution seat has the annular water groove.

[0087] Furthermore, the diameter of the annular water distribution seat is smaller than the diameter of the shower head 2.

[0088] Furthermore, there are three drain outlets 5.

[0089] Furthermore, it also includes a sealing ring 6 and a brewing base 7. The sealing ring 6 is disposed on the brewing head body 1 and located outside the shower blade 2. The brewing base 7 has a coffee outlet 71. The brewing base 7 and the brewing head body 1 are locked together. The shower blade 2 is placed inside the brewing base 7. The sealing ring 6 seals the gap between the brewing head body 1 and the brewing base 7.

[0090] Furthermore, the brewing head body 1 is provided with a cavity 8, and water guide grooves 81 are spaced apart along the circumference of the cavity 8. The water guide grooves 81 are connected to the cavity 8, and the water outlet 11 is provided inside the cavity 8.

[0091] Furthermore, the brewing head body 1 includes a shell 12 and a brewing component 13. The brewing component 13 is disposed in the inner cavity of the shell 12, and the brewing component 13 has the recess 8, the water guide groove 81 and the water outlet 11.

[0092] Furthermore, the water distribution seat 3 is disposed on the concave cavity 8.

[0093] Furthermore, the outer shell 12 is made of aluminum, and the brewing component 13 is made of stainless steel. Both the brewing component 13 and the water distribution base 3 are within the projection range of the shower head 2.

[0094] When water flows out of the outlet 11, due to the concave cavity 8 and the water guide groove 81 arranged along the concave cavity 8 in the aeration component 13, a portion of the water flows rapidly along the water guide groove 81 to the edge of the shower head 2 and directly enters the shower head 2. This path ensures that the water flow can quickly reach the outer area of ​​the shower head 2.

[0095] Meanwhile, another portion of the water enters the concave cavity 8 and flows along the circumference of the concave cavity 8, entering the annular water channel 4 inside the annular water distribution seat 3 set on the concave cavity 8. Since the diameter of the water distribution seat 3 is smaller than the diameter of the shower blade 2, this portion of water is evenly diffused in the annular water channel and then discharged through three evenly arranged drain outlets 5, entering the shower blade 2.

[0096] After being drained, the water is further dispersed at the spaced drain holes 21 on the shower head 2. Since the area of ​​the shower head 2 is larger than that of the water distribution base 3, the water flow forms a uniform coverage across the entire shower head 2, without being confined to the central area. The two water flows complement each other on the shower head, ensuring that the water flow can evenly wet the coffee grounds and improve the overall brewing effect.

[0097] This dual-flow design utilizes the direct guidance of the water guide channel 81 and the uniform diffusion of the concave cavity 8 and the annular water distribution seat, so that when the water flows into the shower head 2, it not only has the characteristic of quickly reaching the periphery, but also achieves uniform distribution on the entire shower head through multi-point discharge, thereby greatly improving the consistency and stability of coffee extraction.
