Background

The safety helmet is a hat which can protect the head of a person from being hurt by falling objects and other specific factors. The safety helmet consists of a helmet shell, a helmet liner, a chin strap, accessories and the like.

The safety helmet that uses at open air building site because the workman need repeated bow and carry out work for the safety helmet has the downward motion trend when bowing to the head, for example, removes the brick, shovel concrete etc. makes the safety helmet drop from overhead easily, and the construction flying dust is great, and the safety helmet can not carry out effectual dust removal to the air that the workman breathed.

To this end, we propose a helmet having a dust removing function to solve the above problems.

Disclosure of Invention

The present invention has been made in view of the above problems, and an object of the present invention is to provide a helmet with a dust removing function that prevents falling off.
