Specifically, when the user wears the helmet, whether the user wears the helmet is determined by wearing the detection sensor 222 or triggering detection of the head of the human body inside the helmet. If the human head is not detected, the human head can be in a shutdown state. When the user wears the helmet, the wearing detection sensor 222 or the trigger switch supplies power to the prompting unit 5. The prompting unit 5 can prompt the user safely in the modes of light, sound, vibration and the like, and remind the user to wear the helmet correctly in time.

In one embodiment, the head-wearing detection unit 22 includes a wearing state detection sensor 221 for detecting a wearing state such as a current wearing angle, direction, and fixed state of the safety helmet.

Specifically, the helmet is provided with a connection member such as a buckle to be fixed to the head, and the state of the buckle is detected by wearing the detection sensor 222 or the trigger switch. After the butt joint of the male head and the female head of the buckle is detected, the user can be proved to wear the helmet correctly. When detecting that the male head and the female head of the buckle are in a separated state, namely, the user does not wear the helmet correctly, the prompting unit 5 at the moment can prompt the user safely in a mode of light, sound, vibration and the like so as to prompt the user to butt joint the buckle in time. After the user butts against the buckle, the prompting unit 5 stops working.

When the helmet is idle, the circuit connection is disconnected by disconnecting the male head and the female head of the buckle, so that the electricity consumption of the prompting unit 5 in the idle state is effectively closed, and the consumption of a battery is saved.

In the actual use process, only after the use state and the wearing state are detected to be qualified, the light is allowed to be emitted.

In one embodiment, the laser intensity detection unit 25 is directly electrically connected to the glasses adjustment unit 23 and the mask adjustment unit 24. When the laser intensity detection unit 25 detects the intensity of the current laser beam, the glasses adjustment unit 23 and the mask adjustment unit 24 automatically start to operate. The signal transmission delay between the helmet control board 21 is reduced, and the safety is higher.

The use flow of the safety helmet of the application is as follows:

Firstly, starting the safety helmet, automatically completing initialization, and detecting whether the helmet is worn on the head of a user or not through a head-wearing detection unit; otherwise, the user is reminded through the prompting unit.

Secondly, when the user wears the helmet on his head, whether the user wears the helmet correctly, such as wearing angle, whether the fastening is firm, etc., is detected by the head-wearing detection unit; otherwise, the user is reminded through the prompting unit.

After the safety detection and reminding are finished, the laser control panel sends out a light emitting instruction, and a user can start a laser processing task.

The laser intensity detection unit can directly control the laser control panel to stop light emission or start light emission in real time according to detected data, delay of signal transmission is reduced, eyes and faces are protected in time, and the protection effect is better.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
