Abstract
Description
Technical Field
[0001] This utility model relates to the field of coffee equipment, and in particular to a coffee water control regulator. Background Technology
[0002] As specialty coffee culture continues to gain popularity globally, coffee extraction has evolved from a basic operation into a technical field requiring precise control. In this process, the decisive role of water flow control in extraction quality has become increasingly prominent, while the inherent defects of traditional coffee machines' direct-flow water outlet structure have become glaringly apparent. This design, used for many years, suffers from three main technical flaws in high-pressure extraction scenarios: When high-speed water directly impacts the coffee grounds without buffering, the coffee particles splatter due to violent collisions, disrupting the uniform structure of the pre-compressed coffee puck. This physical disturbance not only alters the density distribution of the coffee grounds but also creates loose areas, laying the groundwork for uneven extraction later on.
[0003] The water jet formed by a straight-through outlet naturally has a central concentration characteristic, resulting in a noticeably uneven distribution of water flow across the coffee grounds. Excessive water density in the central area leads to over-extraction, while insufficient water flow at the edges results in under-extraction. This contradiction ultimately manifests as an imbalance in the overall extraction of the coffee. Uncontrolled water flow impact energy disrupts the dynamic balance of coffee substance extraction. Ideally, soluble substances should be released in an orderly manner over extraction time; however, in traditional structures, the high-pressure water flow directly impacts the coffee grounds, causing a disordered extraction rhythm. Some areas are under-extracted while others are over-extracted, directly affecting the integrity of the coffee's flavor profile. Utility Model Content
[0004] The present invention aims to overcome the shortcomings of the prior art, where high-speed water flow directly impacts the coffee powder layer, causing coffee powder to splatter and the coffee powder layer to be damaged, resulting in uneven extraction in the subsequent process.
[0005] The technical solution adopted by this utility model is to provide a coffee water control regulator, including a housing assembly and a water flow dispersion device installed in the housing assembly. The housing assembly is provided with a water inlet channel. The housing assembly includes an upper housing connected to a coffee machine on one side and a lower housing on the other side of the upper housing. The water inlet channel is located in the middle of the upper housing.
[0006] By installing the housing assembly of this coffee water regulator at the coffee machine's water outlet, the internal water flow dispersion device slows down and evenly disperses the water flowing in from the middle water inlet channel of the upper housing, preventing water from directly impacting the coffee grounds. This changes the traditional straight-through water outlet structure of coffee machines, which directly impacts the coffee grounds layer at high speed. It not only effectively prevents coffee grounds from splashing due to water impact, but also reduces damage to the coffee grounds layer structure, maintaining the stability of the coffee grounds layer. This allows various flavor substances to be fully extracted during the coffee extraction process, thereby enhancing the layers of coffee flavor and overall quality.
[0007] Furthermore, the upper housing includes a fixing part and an extension part. The fixing part is firmly connected to the coffee machine's water outlet to prevent loosening or detachment due to factors such as water flow impact during use. The extension part is located at the lower end of the fixing part, which extends the water flow path of the middle water inlet channel and plays a transition role. It can limit the water flow range from the coffee machine's water outlet to the water flow dispersion device, so that the water flow enters the water flow dispersion device in an orderly manner. The extension has a first mounting part that mates with the lower housing on the side away from the fixed part. The lower housing has a second mounting part that mates with the first mounting part. The first mounting part and the second mounting part mate with each other to make the upper and lower housings detachable. This not only facilitates the assembly, disassembly and daily maintenance of the coffee water regulator, but also ensures the accuracy of the lower housing's installation position, allowing the upper and lower housings to be precisely aligned during assembly, making the operation convenient and quick.
[0008] Preferably, the first and second mounting parts are magnets mounted on the housing. During assembly, the magnetic attraction properties of the magnets are utilized. When the upper and lower housings are joined, no complicated operating steps or tools are required; simply bringing the upper and lower housings close together will cause the magnets to automatically attract each other, achieving a quick connection. Simultaneously, during operation, even under the impact of water flow and slight vibrations of the equipment, the magnets can automatically adjust their attraction position within a certain range, ensuring that the upper and lower housings maintain a tight connection and accurate position through magnetic attraction. This prevents displacement or loosening, ensuring the overall structural stability of the coffee water controller and enabling it to function properly in water flow control.
[0009] During disassembly, only a certain amount of external force needs to be applied to overcome the magnetic attraction, and the upper and lower shells can be easily separated, making the process simple and convenient.
[0010] Furthermore, the extension section is a downward-expanding cone shape. When water flows in from the inlet channel, the cone shape not only increases the flow area but also allows the water droplets splashing from the water flow impacting the water dispersion device to flow smoothly and evenly back down along the inner wall of the cone towards the downward water dispersion device. The extension section is equipped with an observation window that extends through it, allowing users to monitor the water flow status, such as whether the flow is smooth and the operation of the water dispersion device, without disassembling the equipment. This facilitates the timely detection of potential problems, such as water blockage or uneven water dispersion, enabling prompt action to address these issues and ensure the normal operation of the equipment.
[0011] Furthermore, the lower housing is designed in a ring shape, with the inner circle serving as a mounting hole. This mounting hole provides a clearly defined installation space for the water dispersion device, allowing it to be accurately installed in the designated position. The tight fit between the mounting hole and the water dispersion device effectively resists the impact of the water flow, preventing the device from detaching from the lower housing and ensuring the stability and reliability of the equipment during long-term use. Simultaneously, the water dispersion device, installed within the inner circle of the lower housing, occupies a large area, maximizing the area for receiving and diverting the water flow from the inlet channel. Moreover, as long as the dimensions of the water dispersion device match the mounting hole, it can be adapted to water dispersion devices with different flow rates and diversion specifications, offering a degree of versatility and flexibility to meet the diverse coffee extraction quality requirements of different users.
[0012] Furthermore, the water flow dispersion device includes a housing, a flow distribution layer, and through holes. The flow distribution layer is located inside the housing, and the housing provides a reliable mounting support structure for the flow distribution layer. This allows the housing and the lower housing to cooperate and fix the overall position of the water flow dispersion device. Under the action of external forces such as water flow impact and vibration generated by the coffee machine, the water flow dispersion device can still be guaranteed to work stably within the coffee water control regulator without loosening or displacement, ensuring its continued normal function.
[0013] Meanwhile, the diversion layer diverts the high-speed water flow from the inlet channel, dispersing the large, single stream into multiple finer streams. This reduces the impact force of the water flow, which then flows through the perforations in the diversion layer onto the coffee grounds. This prevents the high-speed water from directly impacting the coffee grounds, thus reducing coffee grounds splashing and protecting the structural integrity of the coffee grounds layer, creating favorable conditions for uniform extraction. Furthermore, the outer shell has a baffle that is higher than the diversion layer, preventing water from the inlet channel from splashing out of the outer shell and water dispersion device after impacting the diversion layer, reducing water waste.
[0014] Furthermore, the outer shell is designed in a disc shape, with a diameter smaller than that of the mounting hole. This allows the outer shell to fit perfectly with the mounting hole in the lower shell, enabling quick and accurate insertion and fixation. Precise positioning ensures the water dispersion device is accurately placed within the coffee water regulator, guaranteeing its proper function and preventing direct water impact on coffee grounds due to installation misalignment. Simultaneously, the regular geometry of the disc-shaped outer shell and the annular lower shell facilitates standardized production, improving efficiency and reducing costs. Moreover, both elements contribute to a more regular, symmetrical, and aesthetically pleasing structure for the entire coffee water regulator.
[0015] Furthermore, the flow distribution layer includes flow distribution pipes distributed throughout the interior of the outer shell, and flow distribution holes located at one end of the flow distribution pipes. When the high-speed water flow from the inlet channel impacts the flow distribution holes, the water flow is divided into multiple smaller streams by the flow distribution holes. This division significantly reduces the impact force of the water flow. At the same time, the dispersed water flow enters the flow distribution pipes through the flow distribution holes, and the flow rate and velocity become stable. Then, it flows along the direction of the flow distribution pipes towards the through holes, allowing the water flow to fall more evenly onto the coffee grounds. This ensures that the coffee grounds can fully and evenly contact the water, avoiding extraction blind zones caused by uneven water flow distribution, and improving the extraction efficiency and quality of the coffee. Preferably, the cross-section of the flow distribution holes is honeycomb-shaped, circular, or rectangular.
[0016] Furthermore, the diameter of the diversion orifice is larger than that of the through orifice. When the water flow from the inlet channel first impacts the larger-diameter diversion orifice, the diversion orifice divides the water flow, achieving an initial slowdown. The slowed water then enters the diversion pipe and, upon entering the smaller-diameter through orifice, its velocity decreases again due to the smaller pipe cross-sectional area. This further streamlines and homogenizes the water flow, achieving a second slowdown. The flow rate and velocity of the water flowing out of each through orifice are more consistent, effectively controlling the final flow velocity from the coffee water regulator. This prevents high-speed water from directly impacting the coffee grounds, ensuring uniform extraction.
[0017] Compared with existing technologies, the advantages of this utility model are as follows: By installing the housing assembly at the coffee machine's water outlet, the upper housing fixing part is firmly connected to the coffee machine's water outlet, preventing loosening or detachment during use. The extension part lengthens the water flow path, acting as a transition, limiting the water flow range, and allowing the water to enter the water dispersion device in an orderly manner. Simultaneously, the upper housing extension part and the lower housing are detachably connected via a first mounting part and a second mounting part. Magnets are preferably used as mounting components, utilizing magnetic attraction properties for quick connection during assembly, eliminating the need for complex operations and tools. During operation, the magnet automatically adjusts its adsorption position, maintaining a tight connection and accurate positioning. Disassembly is easy by applying external force to overcome the magnetic attraction, facilitating assembly, disassembly, and daily maintenance. Furthermore, the extension part is a downwardly expanding cone shape, increasing the water flow area, allowing splashed water to flow smoothly back to the water dispersion device along the inner wall. A through-viewing window is provided, allowing users to observe the water flow status without disassembling the equipment, promptly identifying and addressing problems, and ensuring the normal operation of the equipment. Furthermore, the lower housing is designed in a ring shape with mounting holes in the inner circle, providing a clear positioning and installation space frame for the water flow dispersion device, ensuring accurate installation and resistance to water flow impact. The water flow dispersion device can occupy most of the area to receive water flow diversion and is adaptable to devices with different flow velocities and diversion specifications, exhibiting a certain degree of versatility and flexibility.
[0018] The water dispersion device comprises a housing, a flow divider layer, and through-holes. The housing provides mounting support for the flow divider layer and, together with the lower housing, fixes the overall position, ensuring stable operation under various external forces. The flow divider layer diverts high-speed water flow, dispersing large streams into multiple finer streams, reducing impact force, and then directing the water through the through-holes onto the coffee grounds, preventing direct impact from the high-speed water flow, reducing coffee grounds splashing, and protecting the structural integrity of the coffee grounds layer. Simultaneously, the housing is disc-shaped, with a diameter smaller than the mounting hole diameter, fitting the shape of the mounting hole for quick and accurate embedding and fixation, achieving precise positioning and ensuring the proper functioning of the water dispersion. The regular geometry of the disc-shaped housing and the annular lower housing facilitates standardized production, improving efficiency, reducing costs, and resulting in a neat, symmetrical, and aesthetically pleasing product structure. Furthermore, the flow divider layer includes flow divider pipes distributed throughout the housing and flow divider holes located at one end. The high-speed water flow impacting the diversion orifice is divided into multiple smaller streams, reducing the impact force. After dispersion, the water flows through the diversion orifice into the pipe, where its velocity and flow rate are stabilized. It then flows along the pipe towards the through-hole, ensuring the water is evenly distributed onto the coffee grounds, avoiding extraction blind spots and improving extraction efficiency and quality. The diversion orifice diameter is larger than the through-hole diameter; the water flow first impacts the diversion orifice for initial deceleration, then enters the diversion pipe before entering the through-hole for a second deceleration. This effectively controls the final outflow velocity, ensuring uniform extraction. Furthermore, the diversion orifice cross-section can be designed in various ways, such as honeycomb, circular, or rectangular. Attached Figure Description

Detailed Implementation
[0031] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Example 1
[0032] like Figure 1 and Figure 2As shown, this embodiment 1 provides a coffee water control regulator, including a housing assembly and a water flow dispersion device 400 installed inside the housing assembly. The housing assembly has a water inlet channel 300. The housing assembly includes an upper housing 100 connected to a coffee machine on one side and a lower housing 200 located on the other side of the upper housing 100. The water inlet channel 300 is located in the middle of the upper housing 100. The upper housing 100 includes an annular fixing part 110 connected to the coffee machine's water outlet and extension parts 120 integrally formed at both ends of the lower end of the fixing part 110. Figure 3 and Figure 4 As shown, the extension 120 has a first mounting portion 130 on the side away from the fixing portion 110, which mates with the lower housing 200. Figure 5 and Figure 6 As shown, the lower housing 200 is provided with a second mounting portion 210 that cooperates with the first mounting portion 130. The cooperation between the first mounting portion 130 and the second mounting portion 210 enables a detachable connection between the upper and lower housings 200. Preferably, the first mounting portion 130 consists of six cylindrical magnet blocks embedded in the extension portion 120, and the second mounting portion 210 consists of six cylindrical magnet blocks embedded on both sides of the lower housing.
[0033] Combination Figure 7 As shown, the extension 120 is a downwardly expanding cone shape and has a square observation window 121 that extends through the extension 120. Figure 8 As shown, the lower housing 200 is annular, and the inner circle of the annulus is a mounting hole 220. The water dispersion device 400 is installed inside the lower housing 200 through the mounting hole 220. Figure 9 As shown, the water dispersion device 400 includes a disc-shaped outer shell 410, the diameter of which is smaller than the diameter of the mounting hole 220. The outer shell 410 is nested in the mounting hole 220 of the lower shell 200 for fixation. A flow distribution layer 420 is provided inside the outer shell 410, and the outer shell 410 has a baffle 411 that is higher than the flow distribution layer 420, and a through hole 430 penetrating the flow distribution layer 420.
[0034] like Figure 10 and Figure 11As shown, the flow distribution layer 420 includes flow distribution pipes 421 distributed throughout the interior of the outer casing 410, and flow distribution holes 422 located at one end of the flow distribution pipes 421. The cross-section of the flow distribution holes 422 is honeycomb-shaped, and through holes 430 are located at the other end of the flow distribution pipes 421. The diameter of the flow distribution holes 422 is larger than the diameter of the through holes 430. When the water flow first hits the larger diameter flow distribution hole 422, the flow flow is decelerated for the first time by the flow distribution hole 422. The decelerated water flow enters the flow distribution pipes 421 and then enters the smaller diameter through holes 430. Due to the smaller cross-sectional area of the pipe, the water flow velocity will decrease again, and the water flow will be further sorted and homogenized, achieving a second deceleration. The flow rate and velocity of the water flowing out of each through hole 430 are more consistent, so that the final water flow velocity flowing out of the coffee water regulator is effectively controlled, avoiding high-speed water flow directly impacting the coffee powder and ensuring uniform extraction.
