Multifunctional safety helmet

Abstract

The invention discloses a multifunctional safety helmet. The safety helmet comprises a brim and a shell, wherein a first cavity is formed in the shell, and is filled with water; a first button is arranged in the first cavity; a press plate is connected in the first cavity; a cam is connected in a safety helmet body in a rotating manner, and is driven by a power mechanism; a rubber plate is connected on the wall of the safety helmet body; a second cavity is formed in the rubber plate, and is filled in a water-refrigerant; a water pump is communicated between the first cavity and the second cavity; a heat conductive block supported against the rubber plate is arranged in the shell at one end of the rubber plate; a third cavity is formed in the shell, an expansion block is fixed at the bottom of the third cavity, and the heat conductive block is supported against the expansion block; and a second button is arranged in the third cavity. According to the multifunctional safety helmet, the temperature in the safety helmet body can be adjusted due to the expansion block, the water pump, the water-refrigerant, the cam, the rubber plate and the like, so that the manufacture cost of the safety helmet can be reduced, and the practicality is stronger; and the safety helmet has damping and massaging effects, and has various functions.

Description

technical field [0001] The invention relates to the field of safety protection products, in particular to a multifunctional safety 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...

AI Technical Summary

Problems solved by technology

[0004] Though said scheme has solved the problem that existing desk temperature is not suitable, still there is certain problem: 1, the temperature control in this scheme helmet is realized by the setting of temperature monitor and controller box body, and temperature monitor The price of the controller box is generally higher, which greatly increases the cost of the helmet, and is not practical; 2. The helmet of this solution only has the function of temperature adjustment and protection, and the function is relatively single
