Abstract
Description
Technical Field
[0001] This utility model relates to the field of coffee making technology, specifically to a coffee extraction cup. Background Technology
[0002] Coffee making involves grinding coffee beans into coffee powder, which is then brewed. During the grinding process, an extraction cup is used to collect the coffee powder at the grinder's outlet. The loosely ground coffee powder is then placed in the extraction cup. A tamper presses the powder down to compact it, before the coffee is brewed on the coffee machine.
[0003] In related technologies, a search revealed a solution for a multifunctional coffee extraction cup (publication number CN217937917U). The bottom of the conical extraction cup is connected to the trapezoidal extraction cup. Coffee powder is then placed inside the conical extraction cup. Hot water is injected into the conical extraction cup, and the hot water first extracts the coffee once through the conical extraction cup. Then, the hot water enters the trapezoidal extraction cup through the bottom of the conical extraction cup, and the coffee is extracted a second time through the trapezoidal extraction cup.
[0004] However, after the coffee is brewed, the coffee grounds in the trapezoidal extraction cup need to be cleaned. This requires inverting the trapezoidal extraction cup and tapping it to shake out the compacted coffee grounds. This type of extraction cup needs to be compacted during the coffee brewing process. When cleaning the coffee grounds out of the trapezoidal extraction cup, which is called emptying the grounds, the operation is cumbersome. Alternatively, other tools can be used to empty the grounds, which requires the user to use a lot of force, making it inconvenient to use. Utility Model Content
[0005] The purpose of this invention is to provide a coffee extraction cup to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a coffee extraction cup, including a cup body, a rotating core installed on the lower end face of the cup body, and two spiral grooves provided on the inner wall of the rotating core, the rotating core being able to rotate relative to the cup body;
[0007] The movable core is inserted into the cup body and slidably connected to the cup body. The surface of the movable core has two protrusions that slide with a spiral groove. The middle of the movable core has a liquid outlet tube. Rotating the movable core controls the raising and lowering of the movable core, and the movable core is used to push out the coffee grounds.
[0008] The cup holder is fitted over the rotating core and is rotatably connected to the cup body, thus protecting the rotating core.
[0009] Furthermore, a fixing plate is fitted onto the surface of the rotating core, and the fixing plate is rotatably connected to the rotating core. The fixing plate is fitted with a screw, and the screw is screwed to the cup body. The fixing plate prevents the rotating core from separating from the cup body, thus achieving a rotatable connection between the cup body and the rotating core while ensuring that the rotating core does not loosen.
[0010] Furthermore, the inner wall of the cup body is provided with a rectangular block, and the surface of the movable core is provided with a rectangular groove. The rectangular groove is slidably connected to the rectangular block to ensure the stability of the movable core's up and down movement.
[0011] Furthermore, a sealing ring is fitted onto the side of the movable core, and the sealing ring contacts the cup body, which can better push out coffee grounds and reduce residue.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the movable core is located at the bottom of the cup body, providing space for coffee powder to flow out. Water is poured into the cup body and the coffee powder is squeezed, and the extracted coffee liquid is discharged from the outlet tube. Twisting the cup base drives the rotating core to rotate. The rotating core pushes the protrusions on the movable core to move through the spiral groove. The movable core moves up and pushes the coffee grounds out of the cup body, completing the cleaning of coffee grounds in one go. It is simple to operate and convenient to use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example:
[0021] Please see Figure 1-5 This utility model provides a technical solution: a coffee extraction cup, including a cup body 1, a rotating core 4 installed on the lower end face of the cup body 1, two spiral grooves 13 provided on the inner wall of the rotating core 4, the outer side of the cup body 1 is rectangular and the inner side has a round hole, which is convenient to accommodate the movable core 2 and coffee powder, and the cup body 1 will not slip when held;
[0022] The movable core 2 is inserted into the cup body 1 and slidably connected to the cup body 1. The surface of the movable core 2 is provided with two protrusions 10, which are slidably connected to the spiral groove 13. The middle of the movable core is provided with a liquid outlet tube 11. The spiral groove 13 is used to push the protrusions 10 to move, thereby realizing the upward movement of the movable core 2.
[0023] The cup holder 7 is fitted over the rotating core 4 and is rotatably connected to the cup body 1. The outer part of the cup holder 7 is rectangular, so that the rotating core 4 will not slip when the cup holder 7 is used to drive the rotating core 4 to rotate.
[0024] In this embodiment, as Figure 2 and Figure 4 As shown, a fixing piece 5 is sleeved on the surface of the rotating core 4, and the fixing piece 5 is rotatably connected to the rotating core 4. A screw 6 is inserted into the fixing piece 5, and the screw 6 is screwed to the cup body 1. The fixing piece 5 prevents the rotating core 4 from detaching from the cup body 1, and ensures that the rotating core 4 is stably rotatably connected to the cup body 1.
[0025] In this embodiment, as Figure 2 and Figure 4 As shown, a fixing ring 3 is provided on the upper end face of the rotating core 4. The fixing ring 3 contacts the cup body 1, which reduces the mutual wear between the rotating core 4 and the cup body 1 and reduces the rotational resistance of the rotating core 4.
[0026] In this embodiment, as Figure 5 As shown, the upper end of the active core 2 is provided with a filter 12, which is located above the liquid outlet pipe 11. The filter 12 can prevent coffee grounds from entering the liquid outlet pipe 11, resulting in purer extracted coffee liquid.
[0027] In this embodiment, as Figure 3 As shown, the inner wall of the cup body 1 is provided with a rectangular block 8, and the surface of the movable core 2 is provided with a rectangular groove 9. The rectangular groove 9 is slidably connected to the rectangular block 8. The groove restricts the rotation of the movable core 2 through the rectangular block 8, ensuring that the movable core 2 can only move up and down.
[0028] In this embodiment, as Figure 5As shown, a sealing ring 14 is fitted onto the side of the movable core 2. The sealing ring 14 contacts the cup body 1, and the sealing ring 14 can be used to push the coffee grounds out of the cup body 1 more cleanly.
[0029] Specifically, when using the coffee extraction cup to collect coffee powder, the bottom protrusion 10 of the movable core 2 is at the bottom of the spiral groove 13 of the rotating core 4, creating a height difference between the movable core 2 and the cavity of the cup body 1, thus forming a chamber for holding coffee powder. Coffee powder is added to the cup body 1, water is added to the cup body 1 and squeezed against the coffee powder, and the coffee liquid is filtered and discharged from the liquid outlet 11.
[0030] When you want to empty the coffee grounds in the cup body 1, rotate the cup holder 7. Since the cup holder 7 is fixed to the outside of the rotating core 4, the rotation of the cup holder 7 will cause the rotating core 4 to rotate. The rotating core 4 uses the spiral groove 13 and the protrusion 10 to engage, driving the movable core 2 to move upward along the rectangular block 8 of the cup body 1. The upward movement of the movable core 2 pushes the coffee grounds out of the extraction cup body, completing the cleaning of the coffee grounds in one go.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
