  • Patent number: 11292500
    Abstract: An accommodation device includes a seat assembly, at least one flexible adjustment strap and an accommodating cavity having a bearing portion and a flexible circumferential surrounding portion. The accommodating cavity is rotatable between a lying state and a sitting state. When in the sitting state, a side of the circumferential surrounding portion reaching a topmost point is a first side portion, and a side opposite to the first side portion is a second side portion. The bearing portion has at least two foldable portions forming a first portion close to the first side portion and a second portion far from the first side portion. The adjusting strap is tensioned by the seat assembly and the first side portion when in the sitting state. The second portion is moved to form a seat portion during rotation to the sitting state, and the first portion is supported by the adjusting strap to form a backrest portion.

  • Patent number: 11186306
    Abstract: A handle folding mechanism, a three-fold handle employing the folding mechanism, and a stroller having the same are provided. The folding mechanism includes an intermediate component and a pair of connecting components. The intermediate component includes a tubular casing, a press block, and an unlocking piece. A rear part of the press block passes through a front surface of the casing to extend into the casing, and is movable back and forth. The connecting component includes a tubular housing and an engaging piece. The engaging piece is slidably mounted in the housing. In a locked state, a front end of the engaging piece penetrates into the casing. The unlocking piece has a fixing part, and the fixing part is disposed with a free end extending between a rear end of the press block and the front end of the engaging piece.

  • Publication number: 20190166889
    Abstract: The invention discloses a roasting method for meat based on temperature, including: cooking: cooking the pretreated raw meat to center temperature of 70-80 degree Celsius, and maintaining for 1-2 min; drying: performing drying treatment of the surface of the raw meal: after cooking treatment; roasting: roasting the dried raw meat to surface temperature of 110-120 degree Celsius and maintaining for 5-8 min. The inventive method uses the cooking center temperature and the roasting surface temperature as key control points of roast meat to facilitate on-line monitoring and automatic production, which is an economical and practical new roasting method. The roast meat prepared by the inventive method not only ensures color and flavor of traditional roasting method, but also shortens roasting time. The roasting method can be used for the industrial production of roast meat.
