Description

Technical Field

[0001] This utility model relates to the field of safety helmets, and in particular to a safety helmet with better safety. Background Technology

[0002] A safety helmet is a hat designed to protect the head from injuries caused by falling objects and other specific factors. A safety helmet consists of a shell, liner, chin strap, and accessories. However, every year in my country's construction industry, there are accidents caused by falling objects and accidents resulting from improper helmet use, making it difficult to guarantee the safety of helmet wearers.

[0003] Chinese patent announcement number CN207100650U discloses a high-safety safety helmet, including a helmet shell with an inner liner inside. A cushioning material is fixedly installed between the helmet shell and the inner liner, and an airbag is placed inside the cushioning material. An exhaust nozzle penetrating the helmet shell is fixedly installed at one end of the airbag, and a vent nozzle penetrating the helmet shell is fixedly installed at the other end of the airbag. This high-safety helmet, through the combination of a voice alarm chip, a squeeze-to-release switch, and a socket-to-release switch, allows the helmet to activate when the wearer puts it on, triggered by the downward pressure of the helmet itself. The voice alarm chip then emits an alarm sound or voice prompt. Once the wearer fastens the chin strap, the alarm or voice prompt automatically deactivates, effectively promoting correct helmet use and reducing the occurrence of accidents.

[0004] However, this device has the following drawbacks: While the combination of a voice alarm chip, a squeeze-to-release switch, and a socket-to-release switch can encourage workers to wear safety helmets and reduce accidents, it cannot fundamentally solve the problem of workers' reluctance to wear helmets. Our observations indicate that a major reason workers don't wear helmets is the hot weather, poor breathability of helmets, and excessive sweating during work. To address these shortcomings, we propose a high-safety-level safety helmet. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing safety helmets, such as poor breathability and excessive sweating during work, and to propose a safety helmet with better safety features.

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a safety helmet with improved safety, comprising:

[0007] The safety helmet body includes a helmet body, a brim fixedly installed on one side of the helmet body, and ventilation holes opened on the surface of the helmet body;

[0008] A heat dissipation structure, comprising a power component, an airflow guiding component, and an airflow guiding component;

[0009] The power assembly includes a mounting cylinder fixedly mounted on the surface of the cap body, and a fan fixedly mounted on the inner wall of the mounting cylinder;

[0010] The airflow guide assembly includes an annular guide plate that is fixedly installed on the lower surface of the cap and adapted to the cap, a guide channel opened on the inner wall of the annular guide plate, and multiple exhaust holes that are equidistantly opened on the inner ring surface of the annular guide plate.

[0011] The wind-guiding component is located between the mounting cylinder and the annular guide plate to guide wind into the guiding channel.

[0012] Preferably, the wind guiding component includes an arc-shaped guide frame fixedly installed on the surface of the mounting cylinder, the other end of the arc-shaped guide frame passing through the brim and extending into the interior of the airflow channel, and the arc-shaped guide frame communicating with the interior of the mounting cylinder.

[0013] Preferably, one end of the exhaust hole extends into the interior of the guide channel and forms a 45-degree angle with the annular guide plate.

[0014] Preferably, one end of the mounting cylinder extends into the interior of the cap body and is fixedly fitted with a protective net.

[0015] Preferably, a power supply for powering the fan is fixedly installed on the upper surface of the brim.

[0016] Preferably, the cap body includes a fiberglass cap, a plurality of reinforcing ribs fixedly installed on the inner ring surface of the fiberglass cap, and a rubber pad fixedly installed on the outer ring surface of the fiberglass cap.

[0017] Preferably, the fiberglass cap, brim, and reinforcing ribs are integrally injection molded.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By setting up a heat dissipation structure, when the worker wears the safety helmet, the power unit can guide airflow along the arc-shaped guide frame into the airflow channel and exhaust it through the vents. This airflow can be used to cool the worker. Compared with existing technologies, this device extends one end of the mounting cylinder into the interior of the helmet. When the fan is working, it can draw air from inside the helmet into the mounting cylinder and exhaust it along the arc-shaped guide frame. Outside air will enter the helmet through the vents, thus circulating the airflow and preventing stuffiness caused by poor head ventilation. Furthermore, the airflow entering the arc-shaped guide frame will be exhausted through multiple vents, simulating natural wind blowing over a large area of ​​the worker's head, which can improve the cooling effect. This allows workers to be cooled after wearing the helmet, making them more willing to wear it, reducing the probability of removing the helmet, and improving construction safety.

[0020] 2. By setting up the cap body, rubber pads are placed on the outer ring surface of the cap body. On the one hand, this can buffer the impact of objects hitting the cap body and reduce the amplitude. On the other hand, it can protect the fiberglass cap and prevent it from breaking due to excessive impact. Reinforcing ribs are set inside the cap body to support the entire fiberglass cap, thereby improving the strength of the fiberglass cap and making it safer to wear. Attached Figure Description
