As a preference, the helmet body is provided with an air cushion layer for protecting the head, the air cushion layer is connected to the fan assembly, and the lower part of the air cushion layer is provided with air holes close to the head, through which the head is provided with cool wind to ensure the cooling of the head. At the same time of support, the cool air flow is small and the comfort is better.

Preferably, an illuminating lamp is provided at the front of the helmet body, and the illuminating lamp is connected to the helmet body through a ball joint hinge, so as to facilitate adjustment of the orientation of the illuminating lamp.

Preferably, the grid is rotatably connected to the rainproof cover, and the rainproof cover can be closed when the fan assembly is not needed to prevent dust from entering.

Compared with the prior art, the utility model has the advantages of:

The bluetooth earphones with skull sound transmission, so that the earphones do not block the ears when worn, do not affect the reception of external information, and are more secure; when worn, the pressure sensor sends a wake-up or sleep signal to the bluetooth earphones, which saves more power; by adjusting the contraction structure Adjust the pressure at the joint between the Bluetooth headset and the face to achieve the purpose of manually adjusting or turning off the Bluetooth headset. It is more convenient to control Bluetooth and the learning cost is lower.
