Description

Technical Field

[0001] This utility model relates to the technical field of coffee processing, and in particular to a coffee funnel that is easy to remove the coffee cake and a coffee brewing device. Background Technology

[0002] The coffee hopper of a conventional coffee funnel typically has a vertical inner wall. When the coffee needs to be detached after extraction, the funnel is manually rotated 180° to invert the hopper, and the coffee puck is detached by striking an object, utilizing the relatively large inertia. This striking generates noise and can easily damage the portafilter and the object being struck. To facilitate detachment, some coffee funnels incorporate a puck-pushing mechanism that uses a pressing and spring-back motion to release the puck. However, this design is complex and costly. Therefore, designing a coffee funnel that can easily detach the puck using less inertial force has become a pressing technical problem. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide a coffee funnel that is easy to remove the coffee cake to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, a coffee funnel that facilitates coffee churn removal is designed, comprising: a funnel shell and a powder container disposed within the funnel shell, wherein a water outlet is provided at the lower end of the funnel shell, and a plurality of water outlet holes are provided at the bottom of the powder container, and a first inner sidewall, a second inner sidewall, and a third inner sidewall are provided inside from bottom to top, wherein the inclination angle α of the first inner sidewall is 3°≤α≤10°, the inclination angle β of the second inner sidewall is 6°≤β≤20°, and the inclination angle θ of the third inner sidewall is 0°<θ≤3°.

[0006] By adopting the above technical solution, the coffee caddy is equipped with a first inner wall, a second inner wall, and a third inner wall from bottom to top. The inclination angle α of the first inner wall is controlled to be 3°≤α≤10°, the inclination angle β of the second inner wall is 6°≤β≤20°, and the inclination angle θ of the third inner wall is 0°<θ≤3°. When the coffee needs to be removed after extraction, the coffee funnel is manually rotated 180° to invert the coffee caddy. By using wrist strength to quickly flick one end of the coffee caddy downwards, the coffee cake can be easily removed from the coffee caddy. This method achieves easy removal of the coffee cake using relatively small inertial force. The removal method is simple and does not require hitting objects or a complicated pushing and pressing structure. It will not generate noise due to hitting or damage the handle or the object being hit. The effect is good, and the structure is simple and the production cost is relatively low, which is conducive to its widespread application.

[0009] In some embodiments, the water outlet is fixed to the funnel chamber and the funnel shell by screws.

[0010] In some embodiments, the inclination angle α of the first inner sidewall is 6°, the inclination angle β of the second inner sidewall is 12°, and the inclination angle θ of the third inner sidewall is 0.6°. This achieves a better cake-removal effect.

[0011] In some embodiments, a hanging platform is provided on the upper outer wall of the funnel chamber.

[0012] According to another aspect of this utility model, a coffee brewing device is designed, including a mounting base, a brewing head that moves vertically and vertically with the mounting base, and the aforementioned coffee funnel. The mounting base is provided with a hanging groove, and the lower end of the brewing head is provided with a sealing ring. The upper end of the funnel compartment of the coffee funnel can be inserted into the hanging groove. When the lower end of the brewing head is inserted into the powder compartment of the coffee funnel, the sealing ring is in sealing contact with the inner wall of the powder compartment.

[0013] In some embodiments, the brewing head is provided with a water inlet channel, a water distribution component is provided at the bottom of the brewing head, a groove is provided at the top of the water distribution component, a plurality of water-blocking ribs are evenly distributed on the inner circumference of the groove, a water outlet notch is formed between two adjacent water-blocking ribs, and a vertical through-hole is provided between the water-blocking ribs and the side wall of the groove.

[0014] In some embodiments, a water distribution screen is provided below the water distribution component, and the water distribution screen has several through holes evenly distributed on it. The water distribution screen and the water distribution component are fixed to the brewing head by a screw. During coffee extraction, the water distribution component and the water distribution screen ensure that hot water enters the coffee to be extracted as evenly as possible, guaranteeing uniform coffee extraction.
