Description

Technical Field

[0001] This utility model relates to the field of coffee making equipment technology, specifically to an electric coffee powder dispenser. Background Technology

[0002] High-quality coffee (especially espresso) is made by grinding coffee beans into powder, forming a coffee cake, and then extracting the coffee juice using high-pressure water jets. Uneven distribution of coffee particles during tamping can affect the quality of subsequent coffee extraction, thus impacting the taste. Therefore, coffee powder needs to be distributed before tamping. Existing electric coffee powder distributors use a motor to move a powder dispersing device to agitate the coffee powder, achieving a uniform distribution. However, during use, the agitation of the powder dispersing device causes coffee powder to fly around and adhere to the internal parts of the distributor, making it difficult to clean. Over time, this can lead to problems such as internal parts becoming contaminated, aging, and bacterial growth. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing an electric coffee powder distributor that can rotate and agitate coffee powder while preventing it from flying and sticking to the internal parts of the distributor, thus extending its service life and ensuring safe and hygienic use.

[0043] The powder distributor body 10 is provided with a support member 17 located below the base 40, and the support member 17 is used to support the funnel assembly 50.

[0044] The method of using this utility model is as follows: The funnel assembly 50 containing coffee powder is inserted into the powder distributor. The first motor 23 and the second motor 24 drive the powder-distributing toothed ring 22 to rotate around its own axis while simultaneously moving downwards. As the dispersing needle 251 extends into the funnel assembly 50 through the first through-hole 271 to stir, the first retaining ring 272 slides into contact with the retainer 15, causing the powder-blocking plate 27 to cover the third through-hole 41. The first motor 23 then drives the dispersing needle 251 to continue extending downwards to the bottom of the funnel assembly 50. When the powder distribution assembly 20 moves to the bottom, it abuts against the first stop arm 33. The control board 31 controls the first motor 23 to drive the powder distribution assembly 20 to move upward. The second motor 24 drives the powder distribution gear ring 22 to rotate in the opposite direction. Under the action of the first spring 254, the powder baffle 27 continues to cover the third through hole 41 until the powder distribution assembly 20 moves to the top and abuts against the second stop arm 34. The control board 31 then controls the first motor 23 to move downward.

[0045] In summary, by setting up the powder baffle 27, this utility model can prevent coffee powder from flying into the interior of the powder distributor and adhering to the parts during stirring, thus avoiding contamination, aging, and bacterial growth of the internal parts. Compared with existing electric powder distributors, it has a longer service life and is safer and more hygienic to use.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
