The utility model relates to a knob assembly for cooking equipment. The utility model discloses a base (110) that drive shaft (71) passes through. The utility model has the knob main part (NB) that rotates with the above-mentioned drive shaft (71) as the center and moves linearly with the axial direction of the above-mentioned drive shaft (71). The knob main part (NB) has a locking button (140) with an operating part (143) exposed to the outside. At this time, the locking button (140) has a first position that is restricted from moving axially by the base (110) and a second position that can move axially. Therefore, the user can only press the locking button (140) first, then press the knob main part (NB) axially to make the cooking equipment work, so that the knob assembly can be prevented from being operated or malfunctioning by the locking button (140).

The application discloses a multi-order diffraction grating precision displacement sensor and a displacement measurement method, and relates to the field of displacement sensors.The multi-order diffraction grating precision displacement sensor comprises a laser, a half-wave plate, a first non-polarized light splitting prism, a ±2-order diffraction interference grating precision displacement sensor module and a ±3-order diffraction interference grating precision displacement sensor module.The final displacement measurement result is obtained by weighting the noise levels of the ±2-order diffraction interference grating precision displacement sensor module and the ±3-order diffraction interference grating precision displacement sensor module and then performing calculation.The application provides the multi-order diffraction grating precision displacement sensor, uses the polarization characteristics of light to improve the application rate of effective light, reduces the interference of environmental stray light on the measurement signal, and improves the accuracy and stability of the overall system.
