Description

Technical Field

[0001] This application relates to the field of helmet assistive device technology, specifically to a helmet anti-fog device. Background Technology

[0002] Wearing helmets on motorcycles and electric bikes is a clear requirement of traffic regulations and a reflection of civilized travel. Studies show that wearing a helmet correctly can reduce the rate of head injury by 70% and the mortality rate by 40%; the risk of fatal injury without a helmet is 1.5 times higher than with a helmet. Compliant helmets must meet 3C certification, fit the head properly, and avoid using construction safety helmets as substitutes.

[0003] Proper helmet wearing requires fastening the buckle securely to prevent it from falling off while riding; it should also be adjusted to a comfortable angle, neither tilted forward nor backward. In cold weather, because a properly sized helmet fits snugly against the head, the warm, humid air from breathing can easily cause the windshield to fog up, affecting visibility and safety. At high speeds, air can enter through the gaps between the helmet and the body, clearing the fog from the windshield; however, at low speeds or when stopped, the windshield fogs up rapidly, obstructing vision. Therefore, finding a way to remove windshield fog without removing the helmet is an urgent problem to be solved. Summary of the Invention

[0004] The purpose of this application is to address the problems of fogging on the windshield of ordinary helmets in cold weather, which obstructs vision, and the excessive weight caused by the fogging structure of existing helmets being located on the helmet itself. This application provides a helmet anti-fogging device that delivers airflow directly into the helmet through an air supply duct, with the airflow blowing directly onto the inside of the windshield to achieve rapid defogging.

[0005] The technical solution of this application is as follows:

[0006] A helmet anti-fog device includes an air outlet pipe installed below the helmet visor, a connecting assembly between the air outlet pipe and the helmet, the air outlet pipe being sequentially connected to an air supply pipe and a fan, the fan being connected to the air inlet end of the air supply pipe, and the air outlet end of the air supply pipe being connected to the air outlet pipe; the connecting assembly includes an L-shaped bracket installed above the air outlet pipe, and a buckle being connected to the L-shaped bracket.

[0007] Preferably, a female buckle with a snap fastener is provided below the helmet visor, and a female buckle with a snap fastener is connected to the L-shaped bracket, with the female buckle and the female buckle being compatible.

[0008] Preferably, the L-shaped bracket includes a horizontal bracket plate and a vertical bracket plate. The horizontal bracket plate has a pre-reserved groove I, and the vertical bracket plate has a pre-reserved groove II. Locking bolts I and II are respectively installed in pre-reserved groove I and groove II. The pre-reserved groove I on the horizontal bracket plate allows for easy movement of the L-shaped bracket's exhaust duct, facilitating connection to different helmet models and ensuring the exhaust outlet of the duct is aligned with the inner windshield. Since helmet shapes vary, the female buckle of the buckle may be slightly off-center relative to the bottom of the helmet. The pre-reserved groove II on the vertical bracket allows for fine-tuning of the female buckle in the longitudinal direction, improving installation adaptability.

[0009] Preferably, the air outlet is an L-shaped rigid pipe, with the air outlet extending into the lower part of the helmet and pointing upwards toward the helmet visor.

[0010] Preferably, a magnetic connector is provided between the air supply pipe and the air outlet pipe. The magnetic connector allows the driver to easily disconnect the connection at any time, making it convenient to use.

[0011] Preferably, the air supply pipe is a retractable flexible hose, with its air inlet end connected to the fan outlet.

[0012] Preferably, the fan has an external charging connector.

[0013] Preferably, the fan is also equipped with a fixing buckle.

[0014] The fixed buckle secures the fan to the handlebars of the motorcycle / electric vehicle, eliminating the need to carry the fan with you; you can simply place it on the vehicle. The external charging connector for the fan can also be connected to an external power source such as a power bank, allowing it to be placed on the vehicle as well, reducing the burden on the driver and eliminating the need to carry the entire device on their head and neck, which would otherwise put a lot of strain on their head and neck.

[0015] The beneficial effects of this application are:

[0016] This application features a reasonable design, is convenient and effective in use, and is suitable for riding helmets for motorcycles, electric bicycles, and all-terrain vehicles. The essence of helmet fogging in winter is the liquefaction of hot, humid air inside the helmet upon contact with the cold windshield. When the temperature and humidity inside the helmet are high, while the outside temperature is low, the temperature on the inside of the windshield drops, and the hot, humid air quickly condenses into small water droplets upon contact with the cold glass surface, forming fog. When the motorcycle is traveling at high speed, the gap between the rider and the helmet is sufficient for some air to enter the helmet, preventing fogging of the windshield. However, at low speeds or when the motorcycle is stationary, the air entering through the gap between the rider's head and the helmet is insufficient to overcome the temperature and humidity inside the helmet, thus causing fogging of the windshield. This application's solution can quickly replenish the helmet with air, and the replenishment point is directly blowing onto the inside of the windshield, achieving rapid defogging.

[0017] Excluding the air supply lines and connecting components, the heavier parts of this device, such as the fan and energy storage accessories, can be installed on the vehicle, reducing neck pressure on the helmet wearer. The magnetic connection structure also allows for easy and quick connection and disconnection of the helmet from the vehicle. This makes it convenient to put on and take the helmet away, while the rest of the device remains on the vehicle. Attached Figure Description
