Description

Technical Field

[0001] This utility model relates to the field of coffee barrel technology, and in particular to a spray head for an electric coffee barrel. Background Technology

[0002] Coffee canisters are generally used for brewing coffee, either by boiling water or adding coffee grounds. Typically, a coffee canister consists of a base, a body, a lid, and a water tap. The base contains a heating element for heating the water. To achieve a spray-extraction effect, coffee canisters with a spray structure have been introduced to the market. These have a spray base, a spray column, and an extraction basket. Coffee grounds are placed in the extraction basket, and boiling water vapor is sprayed onto the coffee grounds through the spray column. For example, a large-capacity electrically heated coffee canister is disclosed in patent number CN221903295U.

[0003] The existing spray structure still has significant drawbacks. First, the water vapor is sprayed from the top of the spray column along an irregular path, easily spraying directly onto the inner wall of the barrel lid and then dripping onto the coffee grounds, resulting in uneven water distribution and difficulty in covering the entire extraction basket surface. This not only reduces extraction efficiency but may also affect the coffee flavor due to localized over-extraction or under-extraction. Therefore, further improvements are needed. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a spray head for an electric coffee maker.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a spray head for an electric coffee maker, comprising: a spray tube column and a spray head;

[0006] The spray column is connected to the top of the spray column of the coffee barrel; the spray head includes a diffuser and an arc-shaped top; the lower part of the diffuser is connected to the spray column and has a funnel-shaped structure with an upwardly expanding cross section; the arc-shaped top has an arc-shaped top structure and is fixed to the top of the diffuser; several spray nozzles are opened on the outer periphery above the diffuser.

[0007] Optionally, the bottom side of the arc-shaped top is configured with an arc-shaped surface structure.

[0008] Optionally, several spray nozzles are evenly arranged circumferentially above the diffuser.

[0009] Optionally, the spray nozzles are arranged horizontally or inclined downwards.

[0010] Optionally, the spray head and spray column are injection molded as a single unit.

[0011] Optionally, the inner diameter of the spray column is 8 mm.

[0012] Optionally, the nozzle diameter is 3mm.

[0013] The beneficial effects of this invention are as follows: The diffuser and spray nozzles work together to guide the flow. The trumpet-shaped diffuser design, combined with multiple circumferentially distributed spray nozzles, transforms the concentrated spray of water vapor into multi-directional diffusion, expanding the coverage area and ensuring uniform wetting of the extraction basket surface, avoiding localized over-extraction or under-extraction. The arc-shaped top structure blocks the vertically upward-rushing water vapor, forcing it to diffuse laterally along the spray nozzles, effectively preventing water vapor from directly impacting the inner wall of the lid and dripping down, reducing the randomness of the water flow path, and improving the effective utilization rate of heat energy and water flow. The gradually expanding design of the diffuser can balance the steam pressure inside the spray column, and together with the evenly distributed openings of multiple spray nozzles, it achieves stable and continuous water vapor output, further ensuring the uniformity and consistency of the extraction process.

[0024] Example

[0025] Reference Figure 1 and Figure 2 The present invention proposes a spray head 20 for an electric coffee maker, comprising: a spray tube column 10 and a spray head 20;

[0026] The spray column 10 is connected to the top of the spray column of the coffee barrel; the spray head 20 includes a diffuser 21 and an arc-shaped top 22; the lower part of the diffuser 21 is connected to the spray column 10 and has a funnel-shaped structure with an upwardly expanding cross section; the arc-shaped top 22 has an arc-shaped top structure and is fixed to the top of the diffuser 21; several spray nozzles 23 are opened on the outer periphery above the diffuser 21.

[0027] In this invention, the diffuser 21 and spray nozzles 23 work together to guide the flow. The trumpet-shaped diffuser 21, combined with multiple circumferentially distributed spray nozzles 23, transforms the concentrated spray of water vapor into multi-directional diffusion, expanding the coverage area and ensuring uniform wetting of the extraction basket surface, thus avoiding local over-extraction or under-extraction. The arc-shaped top 22 blocks the vertically upward-rushing water vapor, forcing it to diffuse laterally along the spray nozzles 23, effectively preventing water vapor from directly impacting the inner wall of the lid and dripping down, reducing the randomness of the water flow path, and improving the effective utilization rate of heat energy and water flow. The gradually expanding design of the diffuser 21 balances the steam pressure inside the spray column, and together with the evenly distributed openings of the multiple spray nozzles 23, achieves stable and continuous water vapor output, further ensuring the uniformity and consistency of the extraction process.

[0028] In this embodiment, the bottom side of the arc-shaped top 22 is configured with an arc-shaped surface structure. The arc-shaped surface design of the bottom side of the arc-shaped top 22 further optimizes the water vapor turning path. The arc-shaped surface can reduce the resistance when water vapor comes into contact with the top, guide it to smoothly turn to the spray nozzle 23, reduce turbulence and energy loss; avoid water vapor rebound caused by right angle or planar structure, and reduce ineffective spraying.

[0029] Specifically, several spray nozzles 23 are evenly arranged circumferentially above the diffuser 21. The evenly distributed water flow can form a ring-shaped coverage on the surface of the extraction basket, avoiding insufficient extraction in local areas due to insufficient density of spray nozzles 23; combined with the gradually expanding structure of the diffuser 21, it achieves a spatially balanced distribution of pressure and flow rate.

[0030] In this embodiment, the spray nozzle 23 is arranged horizontally or inclined downwards. This guides water vapor to directly impact the central area of ​​the coffee grounds, reducing the probability of water vapor rising to the lid and enhancing the penetration effect inside the coffee grounds.

[0031] In this embodiment, the spray head 20 and the spray column 10 are integrally injection molded and made of plastic such as PP.

[0032] Preferably, the inner diameter of the spray column 10 is 8mm and the orifice diameter of the spray nozzle 23 is 3mm, which optimizes the spray density and coverage effect.

[0033] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
