The invention relates to the technical field of electric pressure cooker, and discloses a fresh-keeping electric pressure cooker, which comprises a pot body, an outer pot, an inner pot, a sealing ring, an outer cover and an inner cover, wherein a ring with an upward opening is arranged outside the mouth of the inner pot. Groove, the sealing ring includes an upper lip and a lower lip, the upper lip fits the inside of the inner cover, and the lower lip extends into the circumferential groove when the inner cover is fastened; a hose is connected to the inner cover, and one end of the hose is sealed and connected to the The inner side of the inner cover; the pot body is provided with a micro vacuum pump, and the other end of the hose is connected to the micro vacuum pump; the inner cover is provided with a pressure detection device for detecting the gas pressure in the inner pot. The invention solves the problem of short preservation time for the remaining food in the pot, starts the micro-vacuum pump, draws out the residual air in the pot, and the pressure in the pot becomes smaller so that the lower lip is close to the inner wall of the circumferential groove, and the outside air cannot enter, achieving For the purpose of keeping the remaining food fresh for a long time, there is no need for the user to pour out the remaining food for fresh keeping, which greatly facilitates the use of the user.
