Description

Technical Field

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

[0002] A safety helmet is a piece of personal protective equipment, mainly used to protect the head from external forces. In a working environment, workers may face the risk of head injuries due to high-altitude operations, heavy lifting, sharp objects or other potential dangers. Safety helmets can effectively absorb and disperse impact forces and reduce damage to the head. Safety helmet ventilation devices are devices that ventilate the inside of a safety helmet to cool the wearer's head.

[0003] The existing safety helmets have insufficient internal ventilation when worn. In hot weather conditions, the air circulation inside the safety helmet is poor, which will increase the temperature inside the helmet and further increase the wearer's discomfort. If the wearer is in this state for a long time, the body's heat dissipation efficiency will be reduced, and excessive heat accumulation may cause heat stroke.

[0004] Patent document CN202958965U discloses a sun-proof safety helmet, "including a safety helmet, wherein a ring-shaped sun-proof brim is arranged around the safety helmet, the outer side of the sun-proof brim extends out of the safety helmet by 10 to 30 cm, and the inner side of the sun-proof brim is connected to the edge of the safety helmet. Due to the provision of the sun-proof brim, the utility model has both the protective function of a safety helmet and the sun-proof function of a sun hat." However, the sun-proof safety helmet in the above-mentioned public document mainly considers the protective function of a safety helmet and the sun-proof function of a sun hat, but does not consider the problem of improving the internal ventilation of the safety helmet. Therefore, it is necessary to develop a safety helmet ventilation device. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model facilitates improving the ventilation effect of the safety helmet ventilation device by installing a micro-fan and exhaust holes. The micro-fan extracts air inside the installation box to generate wind force. The wind force flows through the bellows, the hose and the connector to make the wind force flow into the flow slot. When the wind force flows inside the flow slot, it absorbs the heat, thereby cooling the head when worn on the forehead. At the same time, after the wind force flows into the exhaust slot, it will flow to the inside of the safety helmet body through the exhaust holes. When the wind force flows inside the safety helmet body, it will carry the heat inside the safety helmet body. After the wind force flows upward and carries the heat into the exhaust component, it flows to the outside through the exhaust component, thereby achieving the purpose of ventilating and cooling the inside of the safety helmet, improving the practicality of the safety helmet ventilation device, and facilitating improving the comfort of the user.

[0015] 2. The utility model installs a sweat-absorbing belt, which facilitates the helmet ventilation device to absorb sweat stains on the user's forehead. The sweat-absorbing belt is made of sponge material. When the user wears the helmet body, the sweat-absorbing belt will contact the wearer's forehead and absorb the sweat stains produced by the wearer. When the sweat-absorbing belt needs to be cleaned, one end of the sweat-absorbing belt is pulled to separate the No. 1 Velcro and the No. 2 Velcro, and then the sweat-absorbing belt can be removed, which makes it easy to clean the sweat-absorbing belt, absorb and remove sweat stains, and effectively avoid the growth of bacteria.
