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

[0013] The plug body is in sealing engagement with the above-mentioned drop hole, and its lower end is connected to the above-mentioned outer ring member via a connecting piece. The above-mentioned outer ring member can drive the above-mentioned plug body to move up and down in the inner ring member via the above-mentioned connecting piece. When the above-mentioned plug body moves to the position of the above-mentioned drop hole, it forms a sealing state with the above-mentioned drop hole. When the above-mentioned outer ring member drives the above-mentioned plug body to move downward relative to the above-mentioned drop hole, an annular gap is formed between the outer annular surface of the above-mentioned plug body and the inner wall of the above-mentioned inner ring member for allowing coffee powder to pass through;

[0014] Wherein, the connecting member passes through the inner ring member, and the inner ring member is provided with a sliding groove adapted to slide the connecting member.

[0015] A further technical solution is that the material storage trough is a gradual notch, and the diameter of the material storage trough gradually becomes smaller along the direction from the notch of the material storage trough to the blanking hole.

[0016] A further technical solution is that the plug body is a cone-shaped body, and the bottom diameter of the plug body is larger than the diameter of the blanking hole;

[0017] The small end of the plug body passes through the blanking hole and extends into the material storage trough, and the large end of the plug body is located in the inner annular member.

[0041] Example

[0042] Please refer to Figures 1-8 , this embodiment provides a coffee powder dropper. The powder dropper is mainly composed of a support assembly, a powder storage part 2 and a plug body 3. The support assembly includes an inner ring part 6 and an outer ring part 4 arranged coaxially. The inner ring part 6 can slide in the outer ring part 4. This design ensures the stability and flexibility of the structure. The powder storage part 2 is provided with a storage trough for storing coffee powder, and a through-type drop hole 12 is provided at the bottom of the storage trough. The inner diameter of the inner ring part 6 is greater than the aperture of the drop hole 12, so that the coffee powder can smoothly pass through the drop hole 12 into the inner ring part 6. The powder storage part 2 is connected to one end of the inner ring part 6 to ensure that the drop hole 12 is coaxial with the inner ring part 6 and the outer ring part 4, ensuring that the coffee powder can fall accurately. The plug body 3, which is sealed with the drop hole 12, is connected to the outer ring part 4 at its lower end through a connector 8. The outer ring part 4 can drive the plug body 3 to move up and down in the inner ring part 6 through the connector 8. When the stopper 3 moves to the position of the discharge hole 12, it forms a seal with the discharge hole 12, preventing coffee powder from accidentally falling out. When the outer ring member 4 drives the stopper 3 downward relative to the discharge hole 12, an annular gap is formed between the outer ring surface of the stopper 3 and the inner wall of the inner ring member 6, allowing coffee powder to fall through this gap. The connector 8 passes through the inner ring member 6, which is equipped with a sliding groove 7 that adapts to the sliding movement of the connector 8, ensuring smooth movement of the stopper 3.

[0043] The coffee powder dropper provided by the present application has many significant advantages in practical use. During use, the operator holds the outer ring member 4, at which time the inner ring member 6 and the powder storage portion 2 naturally fall due to the action of gravity. When the drop hole 12 and the plug body 3 are docked, the plug body 3 forms a sealed state with the drop hole 12, and then the storage tank can be used to receive the coffee powder. Subsequently, the inner ring member 6 is docked at the mouth of the powder bowl 1. When the operator releases the outer ring member 4, the outer ring member 4 falls under the action of gravity. Accordingly, the connecting member 8 slides with the sliding groove 7, and the connecting member 8 drives the plug body 3 to move downward relative to the drop hole 12, and the drop hole 12 is in an open state. In this way, the coffee powder in the powder storage tank falls into the powder bowl 1 through the drop hole 12 and the inner ring member 6. 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, ensuring the cleanliness and hygiene of the coffee powder. This ensures high-quality coffee drinks for consumers, allowing them to enjoy the pure flavor of coffee. Secondly, it ensures that the stopper 3 slides in a directional manner each time, maintaining a uniform and stable gap between the stopper 3 and the hopper. This ensures that the coffee powder falls evenly, preventing accumulation or uneven distribution, significantly improving the quality and efficiency of coffee making. Thirdly, it simplifies the operation process and improves coffee making efficiency. This coffee powder dropper is extremely practical, bringing great convenience to coffee lovers and professionals, making the coffee making process smoother and more efficient.

[0044] Specifically, the coffee powder dropper is usually used in conjunction with the powder bowl 1. During the design, the diameter of the inner ring 6 needs to match the diameter of the powder bowl 1 so that it can be placed above the powder bowl 1, and the inner diameter of the outer ring 4 should be designed to be larger than the diameter of the powder bowl 1. When the inner ring 6 is placed above the powder bowl 1, the outer ring 4 can slide down by gravity.

[0045] 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 12.

[0046] 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 embodiment. This design allows the coffee grounds on both sides of the hopper to move toward the discharge hole 1211. When the discharge hole 1211 is opened, the coffee grounds in the hopper are discharged in a centralized manner, effectively preventing any residue in the hopper.

[0047] In some embodiments of the present invention, the plug body 3 is a cone, and the bottom diameter of the plug body 3 is larger than the diameter of the blanking hole 12;

[0048] The small end of the plug body 3 passes through the blanking hole 12 and extends into the material storage trough, and the large end of the plug body 3 is located in the inner annular member 6 .

[0049] In the above embodiment, the design of the plug body 3 with a conical structure has many advantages. On the one hand, the coffee powder on the upper part of the plug body 3 can flow toward the annular gaps on both sides thereof, effectively avoiding the accumulation of coffee powder. On the other hand, the gradual change structure of the storage trough cooperates with the conical plug body 3, so that the coffee powder in the storage trough is discharged more completely, and the coffee powder discharged from the powder drop hole has a better powder drop effect. In terms of material selection, the surfaces of the storage trough and the plug body 3 that contact the coffee are made of smooth materials, and the smoother the better the effect. In addition, since the diameter of the bottom surface of the plug body 3 is larger than the caliber of the drop hole 12, when the plug body 3 and the drop hole 12 are sealed together, the plug body 3 can limit the powder storage part 2. In this state, if the operator holds the outer ring part 4, the whole composed of the inner ring part 6 and the powder storage part 2 will not fall under the action of gravity, which is convenient for the storage trough to receive the powder, greatly enhancing the practicality of the present application.

[0050] In some embodiments of the present invention, the plug body 3 and the connector 8 may be designed to be detachable or integrally formed; the inner ring 6 and the powder storage portion 2 are preferably designed to be detachable.

[0051] In the above embodiment, the inner ring member 6 and the powder storage portion 2 are detachably matched, and the sliding groove 7 passes through the end face of the inner ring member 6 connected to the material storage portion. Such a design can separate the inner ring member 6 from the material storage portion, and can also be separated from the outer ring member 4 and the plug body 3, so that the entire device can be disassembled into multiple independent individuals. Among them, the plug body 3 and the connecting member 8 can also be detachably matched, further disassembling the present application into multiple independent parts. In this way, the present application can be disassembled into multiple independent individuals, which is more convenient during processing and manufacturing, and each component can be finely processed separately. It is also more convenient during transportation, saving space and reducing costs. In addition, if a local part is damaged, it can be replaced separately to avoid the entire device being unusable due to local damage, which greatly improves the maintainability of the device.

[0052] In some embodiments of the present invention, the inner ring member 6 and the powder storage portion 2 may be designed to be connected by threads; the plug body 3 and the connecting member 8 may also be designed to be detachably connected by bolts, so as to facilitate the rapid installation or removal of the various components of the present invention.

[0053] In some embodiments of the present invention, there are multiple connecting members 8 , and the multiple connecting members 8 are evenly spaced apart along the circumferential direction of the outer annular member 4 .

[0054] In the above embodiment, a plurality of connecting members 8 jointly establish a connection between the plug body 3 and the outer annular member 4, which can effectively improve the stability of the connection between the two.

[0055] In some embodiments of the present invention, the end of the sliding groove 7 away from the powder storage portion 2 extends to the end surface of the inner ring member 6 away from the powder storage portion 2, and the end surface of the inner ring member 6 away from the powder storage portion 2 is coaxially connected with a sealing ring 10 for sealing the end of the sliding groove 7;

[0056] The sealing ring 10 is disposed in the outer ring member 4 , and the sealing ring 10 and the inner ring member 6 are detachably matched.

[0057] In the above embodiment, when the sealing ring 10 is disassembled, the inner ring 6 and the powder storage portion 2 can be separated from the outer ring 4, thereby disassembling the device into multiple independent units. This design facilitates transportation, reduces space occupation, reduces transportation costs, and is also more convenient when maintenance is required.

[0058] In some embodiments of the present invention, the inner annular member 6 is provided with a clamping block 9 , and the sealing ring 10 is provided with a clamping groove 11 adapted to fit the clamping block 9 .

[0059] In the above embodiment, the connection between the clamping block 9 and the clamping groove 11 enables the sealing ring 10 and the inner ring member 6 to be quickly connected or disconnected. In addition, the clamping structure of the clamping block 9 and the clamping groove 11 is multiple groups, which greatly improves the stability of the connection between the sealing ring 10 and the inner ring member 6.

[0060] In some embodiments of the present invention, the outer surface of the sealing ring 10 is provided with anti-slip grooves.

[0061] In the above embodiment, the anti-slip groove design makes the sealing ring 10 less likely to slip during adjustment, which is more practical.

[0062] In some embodiments of the present invention, a handle 5 is symmetrically provided on the outer side of the outer ring member 4 about its central axis.

[0063] In the above embodiment, the design of the handle 5 makes it easy for the operator to hold the handle 5 and operate the product.

[0064] Specifically, the bottom side of the outer ring 4 is provided with multiple openings, and in actual use, any one of these openings can be matched with the handle of the powder basket 1. This design ensures that the handle of the powder basket 1 does not interfere with the movement path of the outer ring 4, ensuring smooth use of the coffee powder dropper.

[0065] 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.
