Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a brewer for a coffee machine. Background Art

[0002] The coffee machine brewer is a core component of the coffee machine for brewing coffee powder. After the coffee powder is brewed by the coffee machine brewer currently on the market, the coffee grounds in the brewing chamber of the brewer need to be pushed out by the top residue plate, and when the power assembly in the coffee machine drives the brewer to move and reset, the scraper plate in the coffee machine can scrape off the coffee grounds remaining on the top residue plate; however, in the existing coffee machine brewer structure, after the top residue plate pushes the coffee grounds out of the brewing chamber, there is no structure for locking the top residue plate. Therefore, in the process of scraping the coffee grounds remaining on the top residue plate, the scraper plate is easy to retract into the brewing chamber, that is, there is a situation where the scraper plate does not completely scrape the coffee grounds from the top residue plate.
