Description

Technical Field

[0001] The utility model relates to the field of safety helmets, in particular to a new type of safety helmet. Background Art

[0002] Safety helmets are a type of personal protective equipment used to protect the head from a variety of injuries. They are especially important in construction sites, industrial production, mining, power operations, road construction, and other environments where there is a risk of head injuries. In these scenarios, safety helmets can effectively block objects falling from above and reduce the risk of head injuries; when walking or working in low spaces, safety helmets can reduce the impact of the head colliding with beams, pipes, or other hard objects, protecting the head from impact injuries, etc.

[0003] The existing safety helmets on the market are composed of a helmet shell, a helmet lining, a chin strap, etc.

[0004] The shell is the main component of the helmet. In order to ensure the rigidity of the shell material, the shell must be an overall smooth structure, and no holes are allowed on the top. This makes the inside of the helmet stuffy, humid and airtight in the hot summer. This will not only affect the work efficiency of the workers, but may even cause the wearer to take off the hat because he cannot stand the stuffiness, which will bring new safety hazards. For this reason, this article provides a new type of helmet. Utility Model Content

[0005] The utility model aims to provide a novel safety helmet with a simple structure and the advantages of being warm in winter and cool in summer.

[0006] The utility model is achieved through the following measures:

[0007] A novel safety helmet, characterized in that it comprises a cooling and ventilation device arranged between the helmet shell and the helmet lining structure;

[0008] The cap lining structure includes a cap lining fixing bracket and a cap lining head wearing ring, the cap lining fixing bracket and the cap lining head wearing ring are connected by four cap lining connecting belts, the entire cap lining structure supports the safety helmet, and the safety helmet is supported and fixed by the cap lining structure when the worker uses the safety helmet;

[0009] The cooling and ventilation device comprises a fan arranged on the cap lining fixing bracket, a fan switch is arranged on the fan, and a solar panel for providing power to the fan is arranged on the outer side of the cap shell. When the fan is working, the solar energy is absorbed by the solar panel, and the light energy is converted into chemical energy and stored in the battery of the fan to supply power to the battery. When the fan is turned off and not in use, the chemical energy can also be stored in the battery. In this way, the fan can be directly charged with the charged battery when there is no sunlight, thereby reducing the dependence on an external independent power source.

[0010] A layer of fine steel mesh is arranged between the fan and the space below to prevent the fan from blowing directly on the workers' heads and causing hair to be caught in the air.

[0011] The specific features of the utility model also include:

[0012] The fan is a miniature centrifugal blower fan, the air outlet of the fan is provided with a ventilation plastic tube, and the side of the helmet shell is provided with a helmet vent. Specifically, it is connected to the helmet vent through the gap between the helmet lining and the helmet shell, and the free end of the ventilation plastic tube is connected to the helmet vent. The fan works through an internally arranged battery, and actively draws out the hot and humid air in the helmet through the principle of centrifugal blowing to avoid direct blowing on the top of the head. The drawn air is connected to the helmet vent through the hollow ventilation plastic tube and sent to the outside of the helmet shell, and sucks in relatively dry and low-temperature external air, forming internal and external air convection, reducing the stuffiness of the helmet in hot weather.

[0013] Both sides of the helmet are provided with a warm attachment 1 for use with the chin bar;

[0014] The thermal insulation accessory 1 includes a thermal insulation block 1, a buckle ring 1 is provided on one side of the thermal insulation block 1, and a button 1 that cooperates with the buckle ring 1 is provided on the inner side of the corresponding cap shell, the thermal insulation block 1 is composed of cloth and internal filling cotton, and the thermal insulation block 1 is connected to the safety helmet through the cooperation of the buckle ring 1 and the button 1;

[0015] The warming accessories 1 on both sides are fixed at the chin by the Velcro connection, which increases the warming area of ​​the cheek and prevents air leakage. The user can adjust the tightness as needed. Specifically, a hook-surface Velcro is provided on the side of the warming block 1 away from the buckle ring 1, and a fleece-surface Velcro is provided on the side of the warming block 1 away from the buckle ring 1 on the other side. The warming blocks 1 on both sides are fixed at the chin by the hook-surface Velcro and the fleece-surface Velcro.

[0016] A second warming accessory for use with the neck is provided on the back of the helmet;

[0017] The second warming accessory includes a second warming block, a second buckle ring is arranged on the upper side of the second warming block, and a second button used in conjunction with the second buckle ring is arranged on the inner side of the rear of the corresponding safety helmet. The second warming block has a similar structure to the first warming block, both of which are made of cloth and internal filling cotton. The second warming accessory is arranged on the rear side of the safety helmet through the cooperation of the second buckle ring and the second button, thereby increasing the warming measures for the neck, and when not in use, the buckle ring can be directly removed from the button, which is convenient for disassembly.

[0018] The beneficial effects of the utility model are:

[0019] The utility model proposes a safety helmet designed for construction sites that is warm in winter and cool in summer. On the basis of the original safety helmet, a small solar charging panel is integrated to power the built-in fan, reducing the dependence on external power supply. The fan promotes the air circulation inside the safety helmet, discharges the hot and humid air inside the helmet, and sends in relatively low temperature and dry air, so as to achieve cooling of workers wearing safety helmets in summer.

[0020] At the same time, detachable thermal insulation accessory 1 and thermal insulation accessory 2 are designed and installed for use in winter. These accessories can be made of thermal insulation materials such as wool or thermal insulation synthetic fibers to keep workers warm when wearing safety helmets in winter and can be disassembled when not in use.

[0021] In this way, on the basis of ensuring the safety of the helmet, the helmet can be worn to keep warm in specific weather. BRIEF DESCRIPTION OF THE DRAWINGS
