Preferably, the upper end of the sliding groove formed in the shell is provided with a locking groove, and the locking groove is communicated with the sliding groove.

The utility model adopts the technical proposal to achieve the following beneficial effects:

1. cool air sucked by the heat dissipation device covers the whole cavity, and the cool air is guided into the cap body through the vent, so that the whole head can achieve the function of cooling;

2. the whole heat dissipation device can be protected through the cap top, and rainwater is prevented from entering the heat dissipation device;

3. the wind shield is brought out by the pull-down deflector rod, so that cold wind can be guided to blow to the neck and the face from the periphery of the cavity, and the wind shield can also protect the neck from being exposed to the sun;

4. the deflector rod can be clamped through the locking groove by pulling the deflector rod upwards so as to prevent the deflector rod from sliding off during construction movement;

5. the elastomer is fully paved through the lining of the cap body, so that the uncomfortable feeling of long-time wearing can be greatly reduced, and the vibration and the noise generated in the operation of the heat dissipation device can be effectively counteracted.
