509 results about "Upper lip" patented technology

The upper lip covers the anterior surface of the body of the maxilla. Its upper half is of usual skin color and has a depression at its center, directly under the nasal septum, called the philtrum, which is Latin for lower nose, while its lower half is a markedly different, red-colored skin tone more similar to the color of the inside of the mouth, and the term vermillion refers to the colored portion of either the upper or lower lip. It is raised by the Levator labii superioris and is connected to the lower lip by the thin lining of the lip itself, which can be seen by opening your mouth wide in front of a mirror. Thinning of the vermilion of the upper lip and flattening of the philtrum are two of the facial characteristics of Fetal alcohol syndrome, a lifelong disability caused by the consumption of alcohol during pregnancy.

Extraction fresh-keeping electric pressure cooker

The invention relates to the technical field of pressure cookers, and provides an extraction fresh-keeping electric pressure cooker which comprises a cooker body, an outer pot, an inner pot, an outer cover and an inner cover, wherein a circumferential groove with an opening facing upwards is formed in the outer side of the opening of the inner pot; a seal ring is arranged between the inner cover and the inner pot, and comprises an upper lip and a lower lip; the upper lip is clung to the inner side of the inner cover; the lower lip is a vertical annular ring; when the inner cover is in a closed state, the lower lip extends into the circumferential groove; a hose is connected onto the inner cover; one end of the hose is communicated to the inner side of the inner cover in a sealed manner; a mini-type vacuum pump is arranged in the cooker body; the other end of the hose is communicated to the mini-type vacuum pump. The extraction fresh-keeping electric pressure cooker has the advantages that the problem of short fresh-keeping time of residual food in the conventional cooker is solved; the mini-type vacuum pump is started to extract residual air in the extraction fresh-keeping electric pressure cooker, so that pressure in the extraction fresh-keeping electric pressure cooker becomes lower, the lower lip is clung to the inner side wall of the circumferential groove, and external air cannot enter the extraction fresh-keeping electric pressure cooker, that is, the purpose of keeping the residual food fresh for a long time can be realized; as a user needs not to pour the residual food out of the extraction fresh-keeping electric pressure cooker for fresh-keeping in another container, the use is more convenient.

Freshness-preserving electric pressure cooker and air extraction control method thereof

The invention relates to the technical field of electric pressure cookers and discloses a freshness-preserving electric pressure cooker. The cooker comprises a cooker body, an outer pot, an inner pot, a sealing ring, an outer lid and an inner lid, wherein a circumferential groove which is in the circle form and opens upward is formed in the outer side of a pot opening of the inner pot, the sealing ring comprises an upper lip piece and a lower lip piece, the upper lip piece is attached to the inner side of the inner lid, and when the inner lid is closed up, the lower lip piece extends into the circumferential groove; the inner lid is connected with a flexible pipe, and one end of the flexible pipe is communicated to the inner side of the inner lid in a sealed mode; a minisize vacuum pump is arranged in the cooker body, and the other end of the flexible pipe is communicated to the minisize vacuum pump; a pressure detection device used for detecting the pressure of gas inside the inner pot is arranged on the inner lid. By means of the freshness-preserving electric pressure cooker, the problem that food left in a cooker is short in freshness-preservation time is solved, the minisize vacuum pump is started, residual air in the cooker is extracted, the pressure in the cooker is lowered, so that the lower lip piece is closely attached to the inner side wall of the circumferential groove, air of the outside world cannot enter, the purpose of long-time freshness-preservation for residual food is achieved, the food does not need to be poured out additionally by a user for additional freshness preservation, and the cooker is greatly convenient for the user to use.

A fresh-keeping electric pressure cooker air extraction control method

ActiveCN105054773BDestruction of overpressure protection performanceTo achieve the purpose of preservationPressure-cookersUpper lipProduct gas
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.
