technical field

The embodiments of the utility model relate to the technical field of household appliances, in particular to a coffee brewing component and a coffee machine.

Background technique

When brewing coffee, the coffee machine needs to put coffee powder into the brewing cavity first, and then compact the coffee powder to be able to brew coffee. After the coffee is brewed, the coffee grounds need to be pushed out of the brewing cavity through the push rod extending into the brewing cavity. Let the coffee grounds fall into the grounds receiving device and collect them uniformly. However, due to the stickiness of coffee grounds, some of the coffee grounds will stick to the end of the push rod during the slag discharge process, and cannot fall by gravity.

To solve this problem, existing coffee machines are usually provided with a powder scraping mechanism for scraping off the coffee grounds. For example, the Chinese utility model patent with the authorization announcement number CN201260608Y discloses a fully automatic or semi-automatic coffee machine brewer, which includes an organic casing, in which a cylinder for brewing coffee is arranged, and the cylinder can be used for brewing coffee. For the piston body that can move up and down in the middle, a rotating rod is installed on the top of the casing near the opening of the cylinder body. After the brewing is completed, the piston body pushes the coffee grounds out of the mouth of the casing cylinder, and the scraper is pushed by the pushing part to push the coffee grounds on the top surface of the piston body into the grounds bucket to complete the scraping operation. However, this type of slag scraping mechanism needs to be driven by a driving device to complete the slag scraping operation, the structure is complex, and the cost is relatively high.
