Description

Technical Field

[0001] The utility model relates to the technical field of coffee tools, in particular to a coffee powder dropper. Background Art

[0002] As people's living standards improve, drinking coffee has become a daily indulgence. To make espresso, first place the coffee beans in the coffee grinder, adjust the grind size to your preference, and then start the machine to grind the coffee to the desired fineness. Next, place the coffee cup under the grinder's outlet to collect the ground coffee. Then, gently pour the grounds from the cup into the machine's basket, ensuring they are evenly distributed. Then, use the coffee tamper to compact the grounds in the basket into a compact cake. After installing the basket, start the machine, allowing high-temperature, high-pressure water to flow through the coffee cake for extraction. After a short while, a rich, full-bodied cup of espresso, rich in crema, is ready.

[0003] In the prior art, the coffee powder collecting cup is generally composed of a cup body and a grippable plug body that fit together. The caliber of the plug body is smaller than the inner diameter of the cup body, so that an annular gap can be formed between the plug body and the cup body for the coffee powder to pass through. The cup body has openings at the top and bottom, and the top opening is larger than the bottom opening. The plug body can extend into the interior of the cup body from the top opening and achieve a sealed fit with the top opening. During actual use, the plug body seals the bottom opening of the cup body and receives coffee powder from the top opening of the cup body. Subsequently, the plug body is pulled away from the bottom opening of the cup body by the handle, so that the coffee powder in the cup flows out from the annular gap between the plug body and the cup body and the bottom opening of the cup body, thereby completing the powder collecting operation. However, this mode of operation mainly has the following problems:

[0004] First, when manually adjusting the stopper, the width of the annular gap between the stopper ring and the inner side of the cup can easily become uneven, making it difficult to ensure that the coffee grounds fall evenly. This is very likely to cause uneven distribution of coffee grounds during subsequent brewing, thus affecting the quality of the espresso.

[0005] Secondly, manually adjusting the stopper is not only inconvenient, but can also contaminate the coffee grounds. During operation, your hands may come into contact with the coffee grounds, or improper operation may allow foreign matter to enter the cup, reducing the purity of the coffee grounds and further affecting the taste and flavor of the coffee.

[0006] Third, manually adjusting the plug requires many steps and it takes a relatively long time to make a cup of coffee.

[0007] The patent with publication number TWM639888U also has the above-mentioned problems. Utility Model Content

[0037] Example

[0038] Please refer to Figure 1-Figure 7, this embodiment provides a coffee powder dropper. The coffee powder dropper mainly includes a powder storage part 2, a plug 6 sealed with a drop hole 11 of the powder storage part 2, and a support assembly. The powder storage part 2 is provided with a storage trough for storing coffee powder. A through drop hole 11 is provided at the bottom center of the storage trough. This design enables the coffee powder in the storage trough to fall stably and evenly. The plug 6 is sealed with the drop hole 11, is slidably arranged relative to the powder storage part 2, and can be moved into the storage trough. The plug 6, the drop hole 11 and the storage trough are coaxially arranged to ensure that the plug 6 moves in the axial direction. When the plug 6 moves to the inside of the storage trough, an annular gap is formed between the outer annular surface of the plug 6 and the inner wall of the storage trough for the coffee powder to pass through, and ensures that the width of the annular gap in the circumferential direction is the same, so that the coffee powder can fall evenly through the gap. The support assembly includes an inner annular member 9, an outer annular member 4 and a connecting member 8. The inner ring member 9, the outer ring member 4 and the drop hole 11 are all coaxially arranged. One end of the outer ring member 4 is arranged on the outside of the powder storage part 2, and the inner ring member 9 is slidably arranged in the outer ring member 4, and the outer side of the inner ring member 9 is connected to the inner side of the outer ring member 4. This design ensures the stability of the relative sliding of the inner ring member 9 and the outer ring member 4. The connecting member 8 is used to connect the inner ring member 9 and the plug body 6. When the inner ring member 9 slides in the direction close to the storage tank, the plug body 6 is driven to move to the inside of the storage tank through the connecting member 8. Among them, the inner diameter value of the inner ring member 9 is greater than the aperture value of the drop hole 11, ensuring that the coffee powder can smoothly pass through the inner ring member 9 and fall into the container below. The design structure of this coffee powder dropper is reasonable, which can effectively achieve the uniform falling of coffee powder, provide convenience for coffee making, and improve the quality and efficiency of coffee making.

[0039] Specifically, the coffee powder dropper is usually used in conjunction with the powder bowl. During the design, the diameter of the inner ring 9 needs to match the diameter of the powder bowl so that it can be placed above the powder bowl, and the inner diameter of the outer ring 4 should be designed to be larger than the diameter of the powder bowl. When the inner ring 9 is placed above the powder bowl, the outer ring 4 can slide down by gravity.

[0040] The coffee powder dropper provided by the present application has shown many significant advantages in actual use. During use, the operator holds the outer ring member 4. At this time, the inner ring member 9 and the plug body 6 naturally fall under the action of gravity and fall to the position of the drop hole 11. The plug body 6 forms a sealed state with the drop hole 11, and then the powder storage tank can be used to receive the coffee powder. Subsequently, the inner ring member 9 is docked with the bowl mouth of the powder bowl. When the operator releases the outer ring member 4, the outer ring member 4 falls under the action of gravity, thereby prompting the plug body 6 to move up relative to the powder storage part 2, so that the drop hole 11 opens. In this way, the coffee powder in the powder storage tank can smoothly fall into the powder bowl through the drop hole 11 and the inner ring member 9. Compared with the traditional powder cup structure, this coffee powder dropper has outstanding advantages. First, it effectively avoids the situation of contacting coffee powder during manual operation, ensures the cleanliness and hygiene of the coffee powder, and presents high-quality coffee drinks to consumers. Second, it ensures that the stopper 6 slides in a directional manner each time, maintaining a uniform and stable gap between the stopper 6 and the hopper. This ensures that the coffee powder falls evenly, preventing accumulation or uneven distribution of coffee powder, significantly improving the quality and efficiency of coffee making. Third, it simplifies the operation process and improves coffee making efficiency. This coffee powder dropper is extremely practical and brings great convenience to coffee lovers and professionals.

[0041] Furthermore, a handle 7 is symmetrically provided on the outside of the outer ring member 4. This design facilitates the operator to hold the handle 7 for operation when using the product. The handle 7 and the outer ring member 4 are detachably connected by bolts.

[0042] In some embodiments of the present invention, the material storage trough is a gradual notch, and the diameter of the material storage trough gradually decreases along the direction from the notch of the material storage trough to the blanking hole 11.

[0043] In the above embodiment, the hopper is designed as a gradual notch. The gradual change can be a gradient or an arc, with the arc being the preferred option. This design encourages the coffee grounds on both sides of the hopper to move toward the discharge hole 11. When the discharge hole 11 is opened, the coffee grounds in the hopper are discharged in a centralized manner, effectively preventing residual coffee grounds in the hopper. Furthermore, the parabolic principle is utilized to ensure that the coffee grounds are distributed more evenly when they fall into the powder bowl.

[0044] In some embodiments of the present invention, the plug body 6 is a cone-shaped body, and the apex of the plug body 6 faces the notch of the material storage tank.

[0045] In the above embodiment, the tapered plug 6 design allows coffee grounds above the plug 6 to flow toward the annular gaps on either side, preventing accumulation. Furthermore, the gradual change in the hopper structure and the tapered plug 6 combine to ensure more complete discharge of coffee grounds from the hopper, and better separation of coffee grounds from the powder dropout holes. Regarding material selection, the surfaces of the hopper and plug 6 that contact the coffee are preferably smooth; the smoother the better.

[0046] In some embodiments of the present invention, the above-mentioned blanking hole 11 is a gradual structure, and the large-diameter end of the blanking hole 11 is close to the above-mentioned storage tank;

[0047] The annular side of the plug body 6 is provided with an annular slope adapted to the blanking hole 11 .

[0048] In the above embodiment, when the plug body 6 and the feeding hole 11 are sealed, the annular slope of the plug body 6 matches the gradually changing feeding hole 11, thus limiting the position of the plug body 6. In this state, if the operator holds the outer annular member 4, the entire body composed of the plug body 6 and the inner annular member 9 will not fall under the action of gravity, facilitating the powder receiving operation of the material storage trough and enhancing the practicality of the present application.

[0049] In some embodiments of the present invention, the outer ring member 4 and the powder storage portion 2 can be designed to be detachable and fit together, or can be designed to be integrally formed; the inner ring member 9 and the connecting member 8 can be designed to be detachable and fit together, or can be designed to be integrally formed; the plug body 6 and the connecting member 8 are preferably designed to be detachable and fit together.

[0050] In the above embodiment, the outer ring member 4 and the powder storage portion 2 are detachably mated, and the inner ring member 9 and the connector 8, as well as the plug body 6 and the connector 8, are also detachably mated. This allows the device to be disassembled into multiple separate units, facilitating processing, manufacturing, and cleaning. It also makes transportation more convenient, saving space and costs. Furthermore, if a component is damaged, it can be replaced individually, preventing the entire device from becoming unusable due to local damage, thereby improving the device's maintainability.

[0051] In some embodiments of the present invention, the outer ring member 4 and the powder storage portion 2 can be designed to be connected by threads; one end of the connecting member 8 and the inner ring member 9 can also be designed to be detachably connected by bolts, and the other end of the connecting member 8 and the plug body 6 can be designed to be plug-in compatible.

[0052] In the above embodiment, the outer ring member 4 and the powder storage portion 2 are connected by threads, providing a secure connection and easy disassembly and installation. The inner ring member 9 and the connector 8 are removably connected by bolts, making operation simple. The bottom of the plug body 6 is partially raised to form a column, which is provided with a slot adapted to receive the connector 8. These connection methods offer the advantage of easy disassembly and installation, enabling the rapid assembly of the present application.

[0053] In some embodiments of the present invention, the number of the connecting members 8 is three, and the three connecting members 8 are evenly spaced apart along the circumferential direction of the inner annular member 9 .

[0054] In the above embodiment, there are three connectors 8, which helps improve the stability of the connection between the inner annular member 9 and the plug body 6. However, it should be noted that three connectors 8 are only one embodiment of this embodiment and are not the only limitation. In other embodiments, the number of connectors 8 can be two or four, and can be flexibly adjusted according to actual conditions.

[0055] In some embodiments of the present invention, the notch of the powder storage portion 2 is detachably provided with a sealing cover 1 .

[0056] In the above embodiment, the design of the sealing cover 1 is very practical. When the material storage tank is not in use, the sealing cover 1 can seal the storage tank, effectively preventing dust and impurities from entering the storage tank, thereby ensuring the cleanliness of the material storage tank during secondary use. Optionally, the sealing cover 1 and the powder storage portion 2 are detachably connected by a thread, facilitating quick installation and removal of the sealing cover 1.

[0057] In some embodiments of the present invention, the powder storage portion 2 is provided with an annular groove 3 for accommodating the sliding of the inner ring member 9 .

[0058] In the above embodiment, the upper end of the inner ring member 9 extends into the annular groove 3 and slides with the annular groove 3. Such a design is conducive to significantly improving the sliding stability of the inner ring member 9, making it more reliable in use.

[0059] Specifically, the bottom side of the outer ring 4 is provided with multiple openings 5. In actual use, any one of these openings 5 ​​can be matched with the handle of the coffee powder basket. This design prevents the handle of the coffee powder basket from interfering with the movement of the outer ring 4, ensuring smooth operation of the coffee grounds dispenser.

[0060] Furthermore, the inner ring member 9 is circumferentially provided with an annular groove 10 on its underside. This groove 10 can be used to engage the rim of the powder bowl. This design not only allows for quick docking of the powder bowl and the inner ring member 9, improving operational efficiency, but also enhances the stability of the docking between the inner ring member 9 and the rim of the powder bowl, ensuring a smooth powder drop process.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
