Description

Technical Field

[0001] This invention relates to a water-filling device for brewing coffee, specifically a water-filling device used in the coffee industry to assist in brewing. Background Technology

[0002] In modern society, all kinds of coffee shops have sprung up like mushrooms after rain. It is common to see people holding a cup of coffee on the street. As one of the most popular beverages today, coffee can not only effectively refresh the mind, but many scientific studies in recent years have also shown that moderate coffee consumption can significantly reduce the risk of certain diseases, especially cardiovascular diseases. With the increasing demand for coffee, more and more varieties of coffee beans have been developed, further driving the development of the coffee market. According to a report on the global coffee market, the global coffee market size reached US$122.9 billion in 2022, and is expected to reach US$170.8 billion by 2030. The huge value behind the coffee market is indeed considerable.

[0003] To enjoy a cup of coffee, brewing is generally required. With the evolution of the times and consumers' pursuit of coffee flavor, in addition to various coffee beans, a variety of brewing methods have emerged. The most common methods include: instant brewing, which only requires adding hot water and waiting for the coffee powder to dissolve; machine brewing, which uses a machine to grind and brew the coffee beans; and manual brewing. In today's fast-paced society, the relatively slow brewing speed of hand-drip coffee still holds a place and even becomes a major trend. This is mainly because hand-drip coffee involves pouring hot water onto coffee powder and extracting the coffee liquid through filter paper and a dripper. With the help of the filter paper, more impurities are filtered out, making the brewed coffee smoother. Moreover, the process of making hand-drip coffee allows one to experience the joy of brewing coffee.

[0004] In the pour-over coffee process, a circular motion is typically performed. Larger circles thin the coffee grounds adhering to the filter paper, allowing the aroma to be extracted more easily since most of the coffee grounds have been washed away by the hot water. Smaller circles result in a thicker coffee grounds wall, leading to a richer brew. Conversely, if the water is poured from a fixed location without circular motion, the coffee grounds at that point may be over-extracted, resulting in a bitter brew. In other words, circular pouring is essential for brewing delicious coffee.

[0005] However, manually pouring water in a circular motion requires practice to consistently brew a good cup of coffee. If the user is not skilled, they may not be able to make a stable circular motion, resulting in the coffee grounds not absorbing water evenly, or too much water being poured into certain areas, causing over-extraction of that part of the coffee grounds. The resulting coffee may be lacking in flavor or too bitter and difficult to swallow.

[0006] In view of this, the inventor has devoted a lot of time to studying relevant knowledge, conducting research and development on related products, and after many experiments and tests, finally launched a water-spraying device that does not require manual circling and can rotate and spray water under external force to make coffee powder absorb water evenly and complete the coffee brewing process, thereby improving the above-mentioned shortcomings and meeting the needs of the public. Summary of the Invention

[0007] The purpose of this invention is to enable a water-pouring device to rotate during the water-spraying process through simple physical principles, thereby ensuring that the coffee powder absorbs water evenly, resulting in a more fragrant and delicious brewed coffee. This avoids the problems associated with conventional manual water-pouring methods, where the brewed coffee may be too weak or too bitter due to variations in user habits and experience. To achieve the aforementioned objective and improve upon the shortcomings of conventional methods, this invention provides a water-pouring device for brewing coffee, comprising: a water-pouring component with a first through-hole penetrating its bottom surface; a connecting component with one end connected to the bottom surface of the water-pouring component and recessed to form a mounting groove communicating with the first through-hole; and a rotating component... The rotating component is partially disposed in the mounting groove. The rotating component includes a receiving portion, an assembly portion, and a second through hole located in the mounting groove. One end of the assembly portion is connected to the receiving portion, while the other end partially extends out of the mounting groove. The second through hole passes through the receiving portion and the assembly portion and communicates with the first through hole. A plurality of ball bearings are disposed in the mounting groove. The ball bearings are arranged in a ring at intervals between the bottom surface of the receiving portion and the bottom surface of the mounting groove, and each ball bearing is respectively in contact with the bottom surface of the receiving portion and the bottom surface of the mounting groove. A water outlet component is assembled with the assembly portion through an assembly hole. The water outlet component includes a plurality of water outlets and a flow channel. The first through hole, the second through hole, the flow channel, and each water outlet are connected. When fluid is discharged from each water outlet, the water outlet component is driven to rotate by an external force. When water is added to the water injection component, the water will pass through the first perforation, the second perforation, and the flow channel in sequence and be discharged from each outlet. The reaction force of the water discharge will drive the water outlet component to rotate. At this time, the rotating component is driven by the water outlet component and rotates in the same direction with the assistance of each ball. The centrifugal force generated during the rotation will make the rotational motion constant and continuous, so that the water outlet component can rotate and spray water stably.

[0008] According to the technology defined above, the advantage of this utility model is that the user only needs to add hot water to the water inlet, and the hot water will flow through the first perforation, the second perforation and the flow channel, and be discharged from the water outlet. The reaction force when the water is discharged can cause the water outlet to drive the rotating part to rotate in the same direction. The centrifugal force generated during the rotation can make the rotation continuous, so that the water outlet can stably rotate and spray water at the same time. This allows the coffee grounds to absorb water evenly when brewing coffee with this utility model, resulting in a more delicious coffee. It avoids the problem of uneven water absorption of the coffee grounds caused by the conventional manual rotation, which results in coffee that is too bland or too bitter. It is evident that this utility model is indeed practical and progressive, and is worthy of promotion in the industry. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0052] The following is a reference to the appendix. Figure 1 To be continued Figure 10 The present invention describes a water-filling device for brewing coffee, comprising: a water-filling component 1 having a first through hole 11 penetrating the bottom surface of the water-filling component 1; a connecting component 2 having one end connected to the bottom surface of the water-filling component 1 and recessed to form a mounting groove 21, the mounting groove 21 communicating with the first through hole 11; and a rotating component 3 partially disposed in the mounting groove 21, the rotating component 3 including a receiving portion 31, an assembly portion 32, and a second through hole 33 located within the mounting groove 21, one end of the assembly portion 32 being connected to the receiving portion 31, and the other end partially extending out of the mounting groove 21, the second through hole... 33 penetrates the receiving part 31 and the assembly part 32 and is connected to the first through hole 11; a plurality of balls 4 are disposed in the mounting groove 21, and the balls 4 are arranged in a ring at intervals between the bottom surface of the receiving part 31 and the bottom surface of the mounting groove 21, and each ball 4 is respectively in contact with the bottom surface of the receiving part 31 and the bottom surface of the mounting groove 21; a water outlet 5 is assembled with the assembly part 32 through an assembly hole 51, and the water outlet 5 includes a plurality of water outlets 52 and a flow channel 53. The first through hole 11, the second through hole 33, the flow channel 53 and each water outlet 52 are connected. When fluid is discharged from each water outlet 52, the water outlet 5 is driven to rotate by an external force. When water is added to the water inlet 1, the water sequentially passes through the first perforation 11, the second perforation 33, and the flow channel 53, and is discharged from each outlet 52. The reaction force of the water discharge drives the water outlet 5 to rotate. At this time, the rotating component 3 is driven by the water outlet 5 and rotates in the same direction with the assistance of each ball bearing 4. The centrifugal force generated during rotation ensures that the rotational motion is constant and continuous, allowing the water outlet 5 to rotate and spray water stably. The drawings used in this document are only for illustrating this utility model and are not intended to limit this utility model.

[0053] This invention allows users to simply pour water into the water inlet 1, and the water will sequentially pass through the first perforation 11, the second perforation 33, and the flow channel 53 before exiting from the outlet. The water discharge generates an action and reaction force; the reaction force acts on the water outlet 5, driving it to rotate. The rotation of the water outlet 5 causes the rotating component 3 to rotate as well. With the assistance of the ball bearings 4, the friction between the rotating component 3 and the connecting component 2 is reduced, making the rotation of the rotating component 3 smoother. The rotation process generates centrifugal force, which helps maintain a constant rotational motion. Furthermore, during rotation, the water outlet 5 continuously sprays water, ensuring that when brewing coffee, after adding water, the rotating water outlet 5 and the rotating component 3 ensure that the coffee grounds are evenly watered, resulting in a more aromatic and flavorful coffee. Figures 1 to 6 As shown.

[0054] Based on the above description, the following further describes other technical and structural features of this utility model. To enable the rotating component 3 to rotate more smoothly when driven by the water outlet component 5, the bottom surface of the mounting groove 21 further has a first groove 211, and the bottom surface of the receiving portion 31 further has a second groove 311. The first groove 211 and the second groove 311 correspond to each other, and each ball bearing 4 is partially and separately attached to the first groove 211 and the second groove 311. When the water outlet component 5 starts to rotate under the reaction force, the first groove 211 and the second groove 311 make it easier for the ball bearing 4 to roll. The rolling of the ball bearing 4 reduces the friction between the rotating component 3 and the connecting component 2, thereby making it easier for the rotating component 3 to rotate under the drive of the water outlet component 5. Figure 3 As shown.

[0055] Furthermore, to achieve a better rotation effect for the water outlet 5 under the influence of reaction force, and to avoid splashing during water spraying, the bottom surface of the water outlet 5 is further cut to form guide slopes 54 on corresponding sides. Each guide slope 54 has a first end face 541 and a second end face 542. Some water outlets 52 are respectively located on the first end face 541 of one guide slope 54, while some water outlets are respectively located on the second end face 542 of the other guide slope 54. By placing the water outlets 52 on the guide slopes 54, excessive splashing of the water outlet 5 during water spraying can be avoided, preventing users from spending extra time cleaning up. By placing the water outlets 52 on different end faces of different guide slopes 54, the problem of the water outlet 5 being pushed back by reaction forces in opposite directions, causing the forces to cancel each other out and preventing the water outlet 5 from rotating smoothly for water spraying operations, can be avoided. Figures 4 to 6 As shown.

[0056] Furthermore, since warming the cups is often required when brewing coffee, i.e., preheating the utensils with hot water, the outer surface of the assembly part 32 is further equipped with a valve 321. Valve 321 controls the opening and closing of the second perforation 33. The user can preheat the water inlet 1 by closing the second perforation 33 and injecting hot water. After preheating, the water is poured out and valve 321 is opened to allow it to flow from the outlet before brewing coffee. This prevents the hot water from cooling down upon contact with the water inlet 1, thus avoiding insufficient temperature after the hot water is sprayed out through the outlet 5, resulting in insufficient flavor in the brewed coffee. Figure 7 As shown.

[0057] In addition, to make coffee brewing easier and more convenient for users, a base plate 60, two support frames 61, a support plate 62, a receiving component 63, and a cup body 64 are provided. The two support frames 61 are correspondingly connected to the base plate 60 at one end, and the corresponding two ends of the support plate 62 are connected to the other ends of the two support frames 61. The support plate 62 is provided with mounting holes 621. The water injection component 1 is placed on the top surface of the support plate 62, and the first through hole 11 corresponds to the mounting hole 621. Connector 2 is connected to water inlet 1 by passing one end through mounting hole 621. Cup body 64 is movably placed on top surface of base plate 60. Container 63 is located between support plate 62 and cup body 64. By assembling water inlet 1 on support plate 62, users can more conveniently brew coffee. Container 63 can be a filter cup or filter holder. Users can put filter paper and coffee grounds in the filter cup, or a drip coffee in the filter holder, and then pour hot water into water inlet. The hot water will be sprayed out through outlet 5 and evenly fall into container 63, then onto coffee grounds before passing through container 63 and falling into cup body 64, thus obtaining a cup of aromatic coffee. Figures 8 to 10 As shown.

[0058] Furthermore, if the container 63 is positioned too low, such as when the filter holder is directly placed on the cup body 64 and a drip coffee bag is placed inside for brewing, the filter holder and drip coffee bag will be directly submerged in the coffee during the later stages of brewing, resulting in a bitter taste and raising hygiene and safety concerns. Therefore, two additional fixing brackets 65 are provided. The two fixing brackets 65 correspond to each other and are each attached to the base plate 60 at one end, with the two fixing brackets 65 spaced apart. The container 63 is movably attached to the other end of each fixing bracket 65 at its corresponding two ends. Through the fixing brackets 65, the user can maintain a certain distance between the container 63 and the cup body 64 when installing it. This avoids the aforementioned coffee bag from being submerged in the brewed coffee, resulting in a bitter taste, and also avoids the hygiene and safety issues of the container 63 being directly submerged in the coffee. Figure 9 As shown.

[0059] Furthermore, to facilitate easier and more secure installation of the housing 63, a plurality of brackets 66 are provided. Each bracket 66 is assembled with a support frame 61. The outer periphery of the housing 63 extends further and is provided with at least one rib 631, which is movably attached to each bracket 66. Users can hang the housing 63 on the fixed frame 65 or bracket 66 via the rib 631, thus preventing coffee powder from spilling during brewing due to instability of the housing 63, which would otherwise result in waste and require time-consuming cleanup. Figure 10 As shown.

[0060] Furthermore, to prevent the water inlet 1 from shifting during the pouring process, thus ensuring the water doesn't fall accurately into the receiving container 63, each support frame 61 has a first recess 611 formed at its top end facing the base plate 60. The corresponding ends of the support plate 62 are respectively engaged with each first recess 611. Each first recess 611 restricts the displacement of the support plate 62. Since the water inlet 1 is assembled with the support plate 62, the user's pouring action prevents the water inlet 1 from shifting due to excessive water impact, thus avoiding disruption to the brewing process. Figures 8 to 10 As shown.

[0061] Continuing from the previous section, to prevent the receiving component 63 from shifting due to external forces, thus preventing the brewed coffee from flowing smoothly into the cup 64, the top of each fixing bracket 65 is further recessed towards the bottom plate to form a second recess 651. The receiving component 63 is movably assembled with the second recess 651, and each second recess 651 restricts the displacement of the receiving component 63. This prevents the user from accidentally pushing the receiving component 63 during the brewing process and interrupting the brewing operation. Figure 9 As shown.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
