Description

Technical Field

[0001] The utility model relates to the field of extraction devices, in particular to a high-pressure extraction funnel. Background Art

[0002] With the improvement of people's living standards, extraction devices have become a tool for people to make beverages. The existing extraction devices usually install an extraction funnel in the extraction device, and the shower head (brew head) arranged in the extraction device will supply water. At this time, the coffee / tea leaves and other items that need to be processed in the extraction funnel will be subjected to high-pressure extraction and brewing, and the water will flow out from the bottom of the extraction funnel to complete the extraction.

[0003] When the existing extraction funnel is used in conjunction with the extraction device, the extraction device needs to manually control the high-pressure extraction time in the extraction funnel or set the high pressure before the extraction work can be completed, which cannot meet the convenience of users. In addition, when the internal water pressure does not reach the set value and the set extraction time is reached first, the extraction funnel will allow the water flow to flow, making the user's taste bad when drinking; or if the water pressure increases but the set time has not arrived, excessive pressure will occur, causing danger.
