1. A welding mask, comprising:
a mask shell;
a darkening filter fixed on the mask shell for adjustment of scale number, sensitivity, and time delay during welding;
a headgear structure rotatably connected to the mask shell for wearing;
a near-eye display module, fixed to the front end of the headgear structure;
a control component fixed on the outside of the mask shell and in communication connection with the darkening filter and the near-eye display module;
wherein the near-eye display module includes a fixed base, connected to the front end of the headgear structure and located at one of the eyebrow centers of the wearer when the operator wears the headgear;
an imaging module housing connected to the fixed base and provided with an imaging lens on the bottom thereof, wherein the imaging module housing is provided with a projection component inside, the projection component is configured to project text and graphic information indicating the working state of the filter and the operating parameters of the welding machine, the projection component is configured to project an image toward the imaging lens that is arranged obliquely and is within the observation range of at least one eye of the wearer; and
wherein an orthographic projection area of the imaging module housing toward the filter is less than one-fourth of the display area of the filter, to reduce the influence of welding adjustment parameters on the operator's operation line of sight;
the near-eye display module is configured to display the working state of the darkening filter and the operating parameters of the welding machine, and the control component further includes a control circuit, a power supply connected to the control circuit, a control knob for controlling the display state of the darkening filter and the near-eye display module, and a communication module connected to the control circuit and in communication connection with the near-eye display module and the darkening filter.
