2results about How to "Function is easy to expand" patented technology

The utility model relates to the technical field of cooking equipment, and disclose a knob assembly and cooking utensil for cooking utensil, knob assembly includes encoder and knob, and encoder includes encoder rotation part and encoder fixed part, and encoder rotation part is rotatable relative to encoder fixed part, and knob is fixedly connected with encoder rotation part, and includes decoration piece, and the side surface of decoration piece away from encoder and the outer peripheral wall of decoration piece all participate in limiting the outer surface of knob, and decoration piece covers the axial outer end of encoder rotation part, and decoration piece is transparent piece. Therefore, the knob assembly has good brand identification, and is convenient for combining with light to realize function extension.

This invention discloses a scalable power very low frequency (VLF) transmitter device and its control method. It consists of multiple individual cabinets, with multiple units sharing a single main control system, facilitating expansion and allowing for power level adjustments, improved waveform quality, and reduced output waveform harmonics. The input terminals of multiple individual power cabinets can be connected in parallel to DC or AC power supplies, and the output terminals are connected in series to the load. Each cabinet includes a switching module, a voltage conversion module, an adjustable voltage module, multiple switching signal modules, multiple multi-tap high-frequency transformers, and a corresponding number of bypass switches. The unique design of the switching signal modules facilitates online expansion and replacement. The high-frequency transformers are multi-tap high-frequency transformers; adjusting the tap positions allows for graded adjustable output voltage after multiple units are connected in parallel. The main control system includes a command control unit, a stepped waveform generation and expansion unit, a storage unit, and a communication unit. The main control system can multiply the comparison value and pulse quantity based on the individual unit comparison value using interpolation methods to provide pulse signals to the switching signal modules.
