Abstract: A cooking device includes an outer pot having a mounting cavity, an inner pot assembly removably arranged in the mounting cavity, a first coupler arranged at the inner pot assembly, an accommodation groove arranged at one of the inner pot assembly and the outer pot, an alignment assembly arranged at another one of the inner pot assembly and the outer pot and configured to be arranged in the accommodation groove, and a second coupler arranged at the outer pot and configured to be plugged with the first coupler.

Abstract: A cooking utensil, the cooking utensil having a first cooking mode includes a pot body assembly, provided with a first heating assembly for heating ingredients in a cooking cavity of the pot body assembly; and a first pot lid assembly, including a pot lid body and a second heating assembly for heating the ingredients in the cooking cavity, and the first pot lid assembly covers the pot body assembly. When the cooking utensil receives a cooking instruction, both the first heating assembly and the second heating assembly heat the ingredients in the cooking cavity, and the cooking utensil is in the first cooking mode.

Abstract: A cooking appliance includes a pot body assembly, a first pot cover assembly, a second pot cover assembly a heating control assembly. The pot body assembly includes a food container configured to hold food and a first heating assembly configured to heat the food in the food container. The second pot cover assembly includes a second heating assembly configured to heat the food in the food container. The heating control assembly is configured to detect a closing state of the second pot cover assembly on the pot body assembly and control the first heating assembly not to operate in response to detecting that the second pot cover assembly is closed on the pot body assembly.

Abstract: The present invention discloses a device for detecting axis coplanarity of orthogonal rotary shafts having a built-in intersection, wherein a front assembly rotary body is coaxially connected on a front assembly housing, the front assembly rotary body and a rear assembly housing are fixedly connected with each other, the rear assembly rotary body is mounted in the rear assembly housing, a first three dimension movement fine tuning mechanism is mounted at an end of the rear assembly rotary body, the first three dimension movement fine tuning mechanism is connected with a standard sphere through a connecting rod, the three dimension movement fine tuning mechanisms are provided in the horizontal direction of the standard sphere and below the standard sphere in vertical direction, and two non-contact displacement sensors are mounted on said two three dimension movement fine tuning mechanisms respectively.

Abstract: A macro-micro actuated distended guide rail precision rotation apparatus, having a housing of a torque motor and a bearing housing, both fixedly arranged on an upper surface of a base, and a bearing sleeved on the bearing housing. The inner ring of the bearing sleevingly connected to an intermediate rotating body connected to a bearing inner ring cap. A grating is provided at a lower end of the bearing inner ring cap. A connecting piece is arranged on the upper surface of the housing of the torque motor. The lower end of the connecting piece is fixedly connected to a rotary shaft of the torque motor. The connecting piece and the intermediate rotating body are both connected to the lower end of a fine movement mechanism fixedly connected to a rotary worktable. The rotation apparatus allows for highly precise macro-and-micro linked control, and for rotation control of great rotation range.
