Description

Technical Field

[0001] The utility model relates to the technical field of coffee machine equipment, in particular to a coffee machine powder scraping mechanism. Background Art

[0002] Coffee machines realize automatic control of the entire process of brewing coffee, including grinding, pressing, filling, brewing, and removing residues. Coffee machines are mainly divided into two categories: semi-automatic coffee machines and fully automatic coffee machines. Since their advent, they have been favored by homes and offices.

[0003] After the coffee is brewed, there will be residual coffee powder in the powder bowl because the powder in the powder bowl has been compressed. When there is too much residual coffee powder, it will affect the normal operation of the coffee machine. The filter hole at the bottom of the powder bowl is small and it is difficult to clean it manually.

[0004] Existing Chinese patent CN 213696578 U discloses an efficient powder scraping mechanism for a coffee machine, which is simple to operate and quick to clean. It includes a coffee machine, a powder bowl and a powder bowl scraping mechanism. The coffee machine is a semi-automatic coffee machine. The powder bowl is connected to the extraction port of the coffee machine through a handle. The powder bowl scraping mechanism is arranged at the right end of the coffee machine. The powder bowl scraping mechanism includes a connecting plate and a support plate. The upper end of the right wall of the connecting plate is provided with a top plate, the lower end is provided with a bottom plate, the center of the support plate is provided with a clamping hole, the left end of the support plate is connected to the connecting plate through a slider, the lower end of the support plate is provided with a U-shaped support frame, a first brush is provided inside the U-shaped support frame, the lower end of the first brush is provided with a telescopic column, a first motor is provided inside the bottom plate, the first motor shaft end is connected to the lower end of the telescopic column, and electric lifting rods are provided at both ends of the telescopic column. A second brush is provided at the upper end of the support plate, and a connecting column is provided at the upper end of the second brush. A second motor is provided inside the top plate, and the second motor shaft end is connected to the upper wall of the connecting column. The efficient powder scraper of this coffee machine operates by turning on the first and second motors, with the first and second motors rotating in opposite directions. The first motor drives the first brush via a telescopic column to rotate, thereby cleaning the outer lower wall of the powder bowl and the filter holes. The second motor drives the second brush via a connecting column to rotate, thereby separating the powder inside the powder bowl from the inner wall. However, the powder scraping mechanism of this patent has low adaptability and cannot be used in combination with different models of coffee machines. Therefore, the utility model proposes a coffee machine powder scraping mechanism to address the shortcomings of the existing technology. Utility Model Content

[0025] When the powder scraping mechanism of the coffee machine of the present invention is installed and used, the powder scraping seat 1 is installed on the bottom of the coffee machine body 3 through the fixing bolts 2. When the powder bowl body 16 needs to be scraped and cleaned, the powder bowl body 16 connected to the coffee machine body 3 is removed, and the powder bowl body 16 is turned upside down on the top of the support seat 4. Then, the powder bowl clamping mechanism 5 is controlled to clamp and fix the powder bowl body 16. At this time, the powder bowl body 16 is concentrically arranged with the main shaft 8. Then, the first electric telescopic rod 6 is used to control the second powder scraping brush plate 12 to descend to the bottom of the powder bowl body 16 and contact the bottom of the powder bowl body 16. Starting the driving motor 13 can drive the main shaft 8 to rotate so that the second powder scraping brush plate 12 rotates to scrape the powder bowl body 16. Bottom powder scraping and cleaning. After the bottom powder scraping and cleaning of the powder bowl body 16 is completed, the first electric telescopic rod 6 is controlled to reset.
