protective helmet

Abstract

The invention discloses a protecting helmet which comprises a helmet brim and a helmet shell, wherein a first hollow chamber is formed in the helmet brim; a second hollow chamber which is communicated with the first hollow chamber is formed in the helmet shell; a heat conducting block is arranged on the helmet brim; a swelling block which is resisted against the heat conducting block is filled in the first hollow chamber; a sliding block is resisted against the swelling block; the sliding block is in sliding connection with the interior of the second hollow chamber; a first button and a second button are arranged in the second hollow chamber; wedge surfaces are arranged on one side of both first button and second button close to the sliding block; a third hollow chamber is arranged in a helmet main body; a cooler is fixedly arranged in the third hollow chamber; the second button is electrically connected with the cooler; a horizontal plate is fixed in the helmet main body under the third hollow chamber; an air vent is formed in the horizontal plate; a fan is fixedly arranged on the third hollow chamber; and the first button is electrically connected with the fan. According to the invention, the swelling block, the sliding block, the fan and the cooler are arranged, so that the temperature of the helmet main body can be adjusted, the manufacturing cost of the helmet can be lowered and the practicability is higher.

Description

technical field [0001] The invention relates to the field of safety protection products, in particular to a protective helmet. Background technique [0002] At present, coal workers need to wear safety helmets when they enter the construction site. However, in hot summer, due to the high temperature, the ventilation effect of safety helmets is limited, resulting in the accumulation of heat in safety helmets, which makes construction workers prone to heatstroke, and some construction workers Also because safety helmet is more stuffy, neglects the safety protection to itself and takes off, thus can't be able to protect the head safety of construction workers. [0003] In order to solve the above problems, the Chinese patent application number 201510152397.0 discloses a temperature-adjustable safety helmet, which includes a safety helmet body, a safety helmet body including a brim and a cap shell, and a refrigerating sheet is arranged on the inner surface of the cap shell, and ...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned scheme has solved the problem that the temperature of the existing desk is not suitable, there are still certain problems: the temperature control in the safety helmet of this scheme is realized by the setting of the temperature monitor and the controller box body, and the temperature monitor and the controller The price of the device box is generally higher, which greatly increases the cost of the helmet, and the practicability is not strong
