Description

Multi-turbofan safety helmet

Technical Field

The utility model relates to a safety helmet; in particular to a safety helmet of a turbofan.

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. Consists of a hat shell, a hat lining, a lower cheek band and a rear hoop. The cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the hit object are mainly borne by the cap shell. A certain space is left between the helmet shell and the helmet liner, and the instantaneous impact force can be buffered and dispersed, so that the direct damage to the head is avoided or reduced. The existing safety helmet has poor ventilation, the internal temperature of the safety helmet can be continuously increased, people can feel uncomfortable when wearing the safety helmet, and even feel sunstroke seriously, so that a fan is added on the safety helmet for cooling.

The invention discloses a rechargeable fan safety helmet with a publication number of CN201798081U in the prior art, and aims to enable the cooling effect of the head and the face to be better and simultaneously not to influence the working convenience, wherein small fans are arranged at the inner top and the foresight position of the helmet body.

The invention discloses a safety helmet additionally provided with a direct current fan, which is named as a safety helmet with a current Chinese patent grant publication No. CN2888925Y, and is characterized in that a helmet body (1) and a visor (2) arranged at the front end of the helmet body (1) are arranged, a mounting plate (3) is arranged on the lower surface of the visor (2), and the direct current fan (4) is arranged on the mounting plate.

Present chinese patent grant publication number is CN206994564U, this utility model provides a take safety helmet of solar fan, this take safety helmet of solar fan, including the cap body, the brim of a hat, solar cell panel, fixed frame, the fan with be curved connecting strip, the brim of a hat is located the bottom of cap body front end, the cap body and brim of a hat formula structure as an organic whole, solar cell panel fixes on the brim of a hat through fixed frame, the one end and the fixed frame of connecting strip link firmly mutually, the other end and the fan of connecting strip link firmly mutually, the fan passes through the wire and links to each other with solar cell panel, the wire embedding is in the connecting strip, the blade of fan is located the place ahead of the brim of a hat.

It has the following problems: 1. the existing turning turbofan is tied on a safety helmet peak shell, and due to long-term blowing towards eyelids, the eyes are subjected to visual angle fatigue, dust enters the eyes and other risks.

Disclosure of Invention

The utility model provides a built-in many turbofan safety helmet that effectively cools down, overcomes visual angle fatigue, prevents that the dust from going into the eye.

The multi-turbofan safety helmet comprises a first cavity, a second cavity, a third cavity and a fourth cavity; the first cavity is arranged on the brim of the safety helmet, a circuit board is arranged in the first cavity, and a fan button is arranged to control the on-off of the turbofan and the wind power gear; the second cavity is arranged on the left side of the cheek of the helmet shell; a first turbofan is arranged inside; the third cavity is arranged on the right side of the cheek of the hat shell, and a second turbofan is arranged in the third cavity; the fourth cavity is arranged at the rear side of the head of the cap shell and internally provided with a third turbofan; the second cavity, the third cavity and the fourth cavity are provided with air supply holes downwards and supply air to the left cheek, the right cheek and the neck and the back.

Furthermore, the whole structure of the turbofan is arc-shaped and is matched with the radian of the cap body.

Furthermore, the side surfaces of the fan blades in the turbofan are distributed in an arc shape and are matched with the radian of the cap body.

Furthermore, a sun shield is arranged on the safety helmet.

The utility model has the advantages that: when the left turbofan and the right turbofan work, wind power supplies air to cheeks and bodies on the left side surface and the right side surface downwards, so that the temperature of the human body is effectively reduced, and the heat dissipation effect of blowing the cheeks is optimal; visual angle fatigue and dust entering the eyes caused by blowing air to the eyes are avoided.

The structure of the turbofan is arc-shaped, is matched with the radian of the cap body, and does not occupy the internal space of the cap; and simultaneously, the extrusion of the fan cover plate to the head part at a right angle is avoided.

The sunshade on the safety helmet increases the use of the helmet, and can reduce the radiation of sunlight for users.
