Safety helmet having airflow rainproof function

Abstract

The invention provides a safety helmet having an airflow rainproof function. The safety helmet comprises a helmet body, wherein an airflow generator is arranged at the top of the helmet body and comprises a base, an airflow guide cover, a direct-current motor and spiral blades. The base is fixedly installed at the top of the helmet body, the airflow guide cover is inversely installed at the top of the base, the direct-current motor is fixedly installed on the lower side of the inside of the airflow guide cover, a rotary shaft of the direct-current motor is upward, and the spiral blades are installed on the rotary shaft. A circular-arc-shaped closed top cover is arranged at the top of the airflow guide cover, multiple air inlets evenly distributed circumferentially are formed in the side wall of the middle of the airflow guide cover, and multiple air outlets evenly distributed circumferentially are formed in the side wall of the upper portion of the airflow guide cover. The airflow generator is installed at the top of the helmet body of the safety helmet, and when the direct-current motor drives the spiral blades to rotate, high-speed airflows discharged out of the air outlets of the airflow guide cover can disperse rainwater flowing down from the top of the head to form a rainwater-free space so as to achieve the rainproof effect.

Description

technical field [0001] The invention relates to a safety helmet, in particular to a safety helmet with an airflow and rainproof function, and belongs to the technical field of protective equipment. Background technique [0002] Rain is a common weather phenomenon. For some people who still need to act outdoors in rainy days, such as construction workers for road or pipeline repairs, police comrades on traffic duty, pedestrians, and cyclists, effective rainproof measures are very important. important. At present, personal rainproof equipment generally adopts raincoats or umbrellas. However, the limitations of raincoats and umbrellas will cause a lot of inconvenience to these personnel's actions. cumbersome and inconvenient. Therefore, we hope to design a kind of not only good rainproof effect, but also can liberate both hands to carry out operation and make the rainproof raingear of people move freely. [0003] The airflow umbrella is an innovative thing that has appeared ...
