[0033] The connecting rod mechanism 3 drives the brewing head 2 to move toward the bottom of the extraction chamber 41 to compress the powder.

[0034] The present invention provides a powder compression and extraction device, which drives a brewing head to be pressed down by a connecting rod mechanism, compresses powder in an extraction chamber, and extracts in the extraction chamber by injecting water through a water injection mechanism, thereby realizing the two functions of powder compression and extraction at the same position at the same time, reducing the extra manual movement of consumers.
