Description

Built-in turbofan safety helmet

Technical Field

The utility model relates to a safety helmet, in particular to a safety helmet with 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 prior chinese patent publication No. CN207561432U discloses a fan for a safety helmet and a safety helmet thereof. The fan for the safety helmet comprises a fan body, the fan body is installed on the outer surface of the safety helmet, the bottom of the fan body is a bent portion, and the bent portion is provided with at least one downward neck air supply opening.

It has the following problems: 1. the existing turning turbofan is bound on the safety helmet shell, wind power loss is large due to the fact that the air outlet direction is changed, the air quantity delivered to the head is weak, the cooling effect cannot be achieved, in addition, the turbine is bound on the safety helmet, the volume and the weight of the safety helmet are increased, the operation safety is influenced by the irregularly-raised external turbofan, and the operation efficiency of workers is reduced.

2. The direction-changing turbofan and the safety helmet are not independent products, and the practicability and the convenience cannot meet the requirements.

Disclosure of Invention

The utility model provides an effective cooling, do not have external equipment, safe and reliable's built-in turbofan ring wind safety helmet (centrifugal fan).

A built-in turbofan safety helmet comprises a first cavity and a second cavity, wherein the first cavity is arranged on a helmet brim of the safety helmet, a circuit board is arranged in the first cavity and used for controlling a turbofan switch and a wind gear, and a turbofan switch/wind gear button is arranged below the helmet brim; the second cavity is arranged at the rear part of the helmet shell and internally provided with a polymer battery, the polymer battery is connected with the first cavity charging circuit board through a wire embedded in the helmet shell, the first cavity turbofan control circuit board is connected with the turbofan, and the turbofan is arranged at the top of the safety helmet; a wind-proof protection plate is arranged below the turbofan; the wind-proof protective plate and the dome of the hat shell form an annular air outlet.

Furthermore, the air inlet of the turbofan is positioned below the turbofan.

Further, the thickness of the turbofan is 10-15 mm.

Further, the annular air outlet is provided with an annular protective net.

The utility model has the advantages that when the turbofan with the centrifugal fan blade structure works, the wind power is transmitted to the periphery, the wind isolation protective plate can protect the head and prevent partial wind power from directly blowing the head top, so that all wind power is sent out from the annular air outlet, the wind quantity surrounds the whole head, and the turbofan is uniform and soft and has no damage to the directly blowing head;

when the safety helmet is used by workers, the heatstroke prevention cooling effect can be achieved, the safety helmet body is not provided with external equipment and redundant openings, and the working efficiency is not influenced

And the thickness of the turbofan is only 10-15mm, and after the turbofan is installed on the top, the inner space between the wind-isolating protective plate and the cap liner is within a standard range and completely meets the safety standard, so that the practicability is high.
