Description

Cooling heatproof helmet

technical field

The utility model relates to a safety helmet, in particular to a cooling and heatstroke prevention safety helmet.

Background technique

Safety helmets are protective equipment to prevent impact objects from hurting the head. Consists of shell, lining, lower chin strap and rear hoop. The cap shell is hemispherical, firm, smooth and elastic, and the impact and puncture kinetic energy of the striking object is mainly borne by the cap shell. There is a certain space between the cap shell and the cap liner, which can buffer and disperse the instantaneous impact force, so as to avoid or reduce the direct injury to the head. Impact absorption performance, puncture resistance performance, lateral rigidity, electrical insulation and flame retardancy are the basic technical performance requirements for safety helmets.

When the worker's head is impacted by falling objects, the helmet shell and cap liner are used to first decompose the impact force to the entire area of the skull, and then use the elastic deformation, plastic deformation and allowable The structural damage of the machine absorbs most of the impact force, reducing the final impact force on the personnel's head to below 4900N, thereby protecting the operator's head. The shell material of the helmet plays an important role in the overall impact resistance of the helmet.

The importance of the role of hard hats is self-evident. It is too hot to wear hard hats in summer, and the inconvenience of working is the main reason why workers are unwilling to wear hard hats. The existing management system not only cannot solve the fundamental problem, but also lacks humanistic thinking. , the existing multiple safety helmets have no heatstroke prevention and cooling function.

Utility model content

In order to solve the problem that workers do not like to wear helmets in summer, and to balance the conflict between the safety management system and the actual situation, from the perspective of man-machine adaptability, a cooling and heatstroke prevention helmet was developed.

The utility model adopts the following technical solutions:

The cooling and heatproof safety helmet includes a cap shell and a cap liner. The cooling and heatstroke prevention safety helmet also includes a DC motor fan installed between the cap shell and the cap liner. The DC motor fan is connected to a battery, and the battery is connected to a solar panel. The battery board is arranged on the outer surface of the cap shell.

Preferably, the storage battery is also connected to a USB charging interface.

Preferably, a switch is provided at the top rib of the cap, the switch is connected to the power supply circuit of the DC motor fan, and the switch is used to control the start and stop of the DC motor fan.

Preferably, the DC motor fan is fixed inside the cap shell by bolts, and an anti-vibration pad with sound-absorbing effect is installed between the DC motor fan and the cap shell.

Preferably, the cap shell and the cap lining form a space adapted to the DC motor fan.

The beneficial technical effect obtained by adopting the above technical scheme is:

The cooling and heatstroke prevention helmet adopts three power supply modes: solar energy, battery, and USB charging. It is green and environmentally friendly, has a wide range of applications, a long service life, and high reliability.

The space occupied by the DC motor fan is very small, does not affect the normal performance of the helmet, and can be disassembled according to the season. Under the premise of not affecting the safety performance of the helmet, the cooling heatproof helmet can promote the air flow inside the helmet, reduce the temperature inside the helmet, solve the heat dissipation problem of the helmet, and have broad market prospects.

Detailed ways

The specific embodiment of the utility model is further described in conjunction with accompanying drawing 1 to 2:

The cooling and heatstroke prevention safety helmet includes a cap shell 1 and a cap liner 2. The cooling and heatstroke prevention safety helmet also includes a DC motor fan 6 installed between the cap shell 1 and the cap liner 2. The DC motor fan is connected to a battery connected to the battery. There is a solar battery panel 3, and the solar battery panel 3 is arranged on the outer surface of the cap shell. The hat shell includes visor, hat brim, top rib, air vent, socket, bolt lining belt hole and chin strap hanger. The hat liner includes the top band of the hat hoop, the support belt, the support belt, the sweat band, the pad and the tether.

The storage battery is also connected with a USB charging interface. The top rib of the cap shell is provided with a switch 5, which is connected to the power supply circuit of the DC motor fan, and the switch is used to control the start and stop of the DC motor fan. The solar panel converts solar energy into electricity for the DC motor fan to work. The storage battery is preferably a storage lithium battery. When there is not enough solar energy, the lithium battery can work for 2 hours. When the solar energy is sufficient, the storage battery can also be charged. USB charging interface, when sufficient solar energy cannot be provided for a short period of time, it can be charged by connecting the mobile phone charger.

The DC motor fan is fixed inside the cap shell by bolts 4, which facilitates the disassembly and installation of the DC motor fan, and can be disassembled according to the seasons. An anti-shock pad with sound-absorbing effect is installed between the DC motor fan and the cap shell to eliminate the vibration and noise generated by the DC motor fan and avoid affecting the comfort of wearing.

The cap shell and the cap liner form a space suitable for the DC motor fan. The horizontal spacing of this space: when the helmet is worn, the distance between the hoop and any horizontal point in the space around the shell; the vertical distance of this space: the vertical distance between the top of the head and the inner top of the shell when the helmet is worn ( Does not include top rib space). The DC motor fan can rotate freely inside.

When in use, the staff wearing the cooling and heatstroke prevention helmet only need to turn on the switch, and the DC motor fan works to make the air flow in the hat, promote the evaporation of sweat, and achieve the effect of heatstroke prevention and cooling.

Of course, the above descriptions are only preferred embodiments of the present invention, and the present invention is not limited to the above-mentioned embodiments. It should be noted that any person skilled in the art can make all the Equivalent substitutions and obvious deformation forms all fall within the essential scope of this specification and should be protected by the utility model.
