Description

Technical Field

[0001] The utility model relates to the technical field of electric power helmets, in particular to an intelligent ventilation electric power helmet. Background Art

[0002] In the power industry, power workers often need to work for long periods of time in high temperature, high humidity or confined spaces. Traditional power helmets often lack effective heat dissipation mechanisms, causing the wearer's head to overheat, affecting work efficiency and health and safety.

[0003] To address the aforementioned issues, Chinese patent application CN201920947676.X discloses an electric safety helmet designed to improve construction safety. The helmet comprises a cap body, a brim, and a chin strap. The brim is mounted on the sidewall of the cap body, and the chin strap is mounted at the bottom end of the cap body. A voltage sensor is mounted inside the cap body, electrically connected to a control chip, which is electrically connected to a vibration device, a power module, and a buzzer. The power module is equipped with a master switch for controlling the entire circuit and is mounted on the side of the cap body away from the brim. The control chip is electrically connected to a temperature sensor, which controls a cooling fan mounted on the inner wall of the cap body. However, this electric safety helmet designed to improve construction safety has the cooling fan mounted on the inner wall of the cap body. This allows the cooling fan to only draw air in one direction inside the cap body. The airflow is first concentrated in the fan's outlet direction for cooling, and then diffuses. This design can easily lead to uneven airflow distribution within the cap body, resulting in slow heat dissipation and cooling efficiency. Utility Model Content

DETAILED DESCRIPTION

[0029] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] like Figures 1 to 4As shown, a smart ventilated electric helmet comprises a helmet body 1, a cooling fan 2, a circuit control board 3, a battery module 4, a brim 5, a first air duct 6, a second air duct 7, and an air hood 8. The helmet body 1, serving as the main structure of the helmet, is made of lightweight, high-strength materials, ensuring both wearing comfort and adequate protection. The circuit control board 3 is electrically connected to the cooling fan 2, which is driven by the circuit control board 3 to precisely dissipate heat from the wearer's head. The battery module 4 provides power to the circuit control board 3 and the cooling fan 2, providing a stable power supply for continuous operation and ensuring operational safety. A mounting opening 11 is defined at the middle and rear end of the helmet body 1, which connects to the inner cavity of the helmet body 1 and is used to mount the cooling fan 2. The brim 5 is connected to the front end of the helmet body 1. In addition to providing sun protection, the brim 5 features a second air duct 7 on its top surface, which connects to the first air duct 6 and directs airflow toward the face, enhancing overall cooling. Preferably, the helmet body 1 and the brim 5 are integrally formed and are both made of ABS material. ABS material refers to acrylonitrile-butadiene-styrene copolymer, a thermoplastic polymer structural material with high strength, good toughness, and easy processing and molding, also known as ABS resin. The first air duct 6 is connected to the inner wall of the helmet body 1 and extends from the rear end of the helmet body 1 to the front end of the helmet body 1; the first air duct 1 is provided with a plurality of air outlet holes 61 along its length; the first air duct 6 is connected to the inner wall of the helmet body 1 and extends from the rear end of the helmet body 1 to the front end of the helmet body 1, forming the main air flow channel, and is provided with a plurality of air outlet holes 61 along its length to ensure that the cold air is evenly distributed to every corner of the interior of the helmet. The second air duct 7 is connected to the top surface of the brim 5 and is connected to the first air duct 6; the brim 5 has an air outlet 51 that is connected to the second air duct 7 and has an opening that is tilted downward to blow air toward the face of the person; the second air duct 7 guides the airflow to the brim 5 area and blows it toward the wearer's face through the air outlet 51 on the brim 5. The air outlet 51 is tilted downward to avoid blowing directly into the eyes, thereby improving wearing comfort. The air hood 8 is connected to the first air duct 6 and covers the position of the mounting port 11, and is connected to the inner wall of the helmet body 1 to guide the airflow into the first air duct 6. The air hood 8 is connected to the first air duct 6 and is set corresponding to the position of the mounting port 11, effectively guiding the cold air generated by the cooling fan 2 to flow along a predetermined path, achieving a good diversion effect and enhancing heat dissipation efficiency.

[0031] On the basis of the helmet body 1, the cooling fan 2, the circuit control board 3 and the battery module 4, a brim 5, a first air duct 6, a second air duct 7 and an air hood 8 are added and combined. The first air duct 6, the second air duct 7 and the air hood 8 are rationally designed into a unique air duct system. The circuit control board 3 is used to intelligently control the operation of the cooling fan 2 to form an air flow through the air duct system and outflow from the specially designed air outlet 61 and the air outlet 51. By adjusting the outlet direction of the air flow, the temperature of the wearer's head and face is significantly reduced, the heat dissipation efficiency is high, and it helps to improve the working comfort and safety of power workers in high temperature and closed environments.

[0032] Preferably, the front end of the air hood 8 is connected to the rear end of the first air duct 6; and the rear end of the air hood 8 is tilted toward the position of the cooling fan 2. With this design of the position and direction of the air hood 8, when the cooling fan 2 is operating, the air flow can be better introduced into the first air duct 6 for ventilation, heat dissipation and cooling, thereby achieving a high heat dissipation effect.

[0033] To maximize the heat dissipation and air outlet area, the first air duct 6 is designed in a flat, arc-shaped structure. This design increases the width of the first air duct 6 in the left-right direction relative to the helmet body 1, occupies less space in the vertical direction of the helmet body 1 than a tubular air duct, and allows for more air outlet holes 61 to be designed more conveniently, effectively improving air outlet efficiency and achieving rapid ventilation and cooling.

[0034] In order to improve the wearer's comfort when wearing the intelligent ventilation power helmet, it is possible to consider installing a head cover bracket 9 that fits the head on the inner wall of the helmet body 1. At the same time, the head cover bracket 9 can create a gap between the head and the inner wall of the helmet body 1, and the heat dissipation effect is better.

[0035] In this embodiment, the circuit control board 3 and battery module 4 are installed between the rear inner wall of the helmet body 1 and the head hood bracket 9 via a junction box 10. The head hood bracket 9 effectively separates the junction box 10, thereby improving the wearer's comfort when wearing the intelligent ventilated power helmet. The intelligent ventilated power helmet also includes a temperature sensor 20, a voice module 30, and a lighting panel 40. The temperature sensor 20 is located on the inner wall of the helmet body 1. The cooling fan 2 is driven by the circuit control board 3, which uses the temperature sensor 20 to monitor the temperature inside the helmet body 1 in real time. The circuit control board 3 automatically adjusts the speed of the cooling fan 2 based on the detected temperature inside the helmet body 1, achieving precise heat dissipation. The voice module 30 is installed within the junction box 10, and the circuit control board 3 is electrically connected to the temperature sensor 20 and voice module 30, respectively. The circuit control board 3, battery module 4, and voice module 30 are centrally installed within the junction box to avoid occupying space inside the helmet body 1 due to the installation of these components. To facilitate working in dark environments, a lighting panel 40 is attached to the front of the brim 5. Connected to the front side of the lighting panel 40 is an LED light strip 50, which is electrically connected to the circuit control board 3. Mounting the LED light strip 50 on the front side of the lighting panel 40 prevents glare from entering the wearer's eyes. Furthermore, the LED light strip 50 is compact and bright, making it easier for the wearer to work. The battery module 4 supplies power to the cooling fan 2, temperature sensor 20, voice module 30, and LED light strip 50 through the circuit control board 3.

[0036] It should be noted that the cooling fan 2, circuit control board 3, battery module 4, temperature sensor 20, voice module 30, and LED light strip 50 are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. The specific implementation of this application may involve the use of software, but the software used is the most commonly used software by those skilled in the art and is not within the scope of protection of the claims of this patent application.

[0037] In summary, the embodiment of the present invention provides an intelligent ventilation power helmet, in which, on the basis of the helmet body 1, the cooling fan 2, the circuit control board 3 and the battery module 4, a brim 5, a first air duct 6, a second air duct 7 and an air hood 8 are added and combined. The first air duct 6, the second air duct 7 and the air hood 8 are rationally designed into a unique air duct system. The circuit control board 3 is used to intelligently control the operation of the cooling fan 2 to form an air flow through the air duct system and flow out from the specially designed air outlet 61 and the air outlet 51. By adjusting the outlet direction of the air flow, the temperature of the wearer's head and face is significantly reduced, the heat dissipation efficiency is high, and it helps to improve the working comfort and safety of power workers in high temperature and closed environments.

[0038] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
