[0002] When driving a two-wheeled motor vehicle, the rider needs to wear a helmet to protect the rider from head injuries in the event of an accident.

[0003] When wearing a helmet in winter or in cold areas, the goggles of the helmet are usually closed for the purpose of keeping warm. However, due to the temperature difference between the inside and outside of the helmet, the hot air exhaled by the wearer in the helmet will condense and fog up on the goggles when it encounters cold, affecting normal use. In the prior art, in order to solve the fogging problem, the goggles of the helmet are mostly anti-fogging treated, such as adding an anti-fogging film to the inner lens of swimming goggles. Within a certain period of time, it can play a good anti-fogging role. However, after a long period of use, the anti-fogging film is damaged, and the anti-fogging effect will gradually be lost. Therefore, an anti-fogging head cover for a helmet is proposed to be used in conjunction with a helmet to solve the problems existing in the prior art. Utility Model Content

In this embodiment, a support strip mounting groove 1-4 is arranged on the top of the facial covering layer. The support bar installation groove is in the shape of an arc, and a flexible support bar is sewn in the support bar installation groove. The flexible support bar can be made of flexible metal. When the headgear is worn, the flexible support bar is plundered to fit the bridge of the nose and the curve of the face, so that the lower breathing area is separated from the upper sight area. When breathing, the hot air exhaled from the mouth and nose cannot rise to the eyes, and thus will no longer contact the helmet's goggles, but will go down along the breathing area and be discharged from the bottom of the headgear, thereby achieving the effect of preventing fogging during the wearing of the helmet and improving driving safety;

[0024] In addition, in the present embodiment, two one-way air inlet valves are provided in the breathing zone, through which fresh air from outside is sucked in, while exhaled waste gas is not discharged from the one-way air inlet valve, thereby ensuring smooth breathing. The wearer can continuously inhale fresh air, which is beneficial to ensuring the physical and mental health of the wearer.

[0025] To be more specific, the one-way air intake valve 2 includes an air intake valve top cover 2-1, an air intake valve base 2-2, and an air intake diaphragm 2-3. The air intake diaphragm 2-3 is movably arranged on the air intake valve base 2-2. The air intake valve top cover 2-1 is socketed with the air intake valve base 2-2. The one-way air intake valve has three structural parts, and the main structural part is the air intake diaphragm. During the installation process, the air intake valve top cover needs to be set toward the wearer's side. When inhaling, the air intake diaphragm is sucked up, and the external air enters the head cover through the gap between the air intake diaphragm and the air intake valve base. When exhaling, the air intake diaphragm is pressed back to the air intake valve base by the airflow for sealing, which prevents the exhaled exhaust gas from entering the helmet. This not only ensures that the wearer can continue to breathe fresh air from the outside, but also is an important link in preventing the exhaled hot air from rising.

[0026] To be more specific, the air intake valve top cover 2-1 includes a top cover bottom plate 2-1-1, the top cover bottom plate 2-1-1 is an annular structure, a connecting outer wall 2-1-4 is arranged on the middle edge, a shielding top plate 2-1-2 is arranged above the connecting outer wall 2-1-4, a plurality of partition bars 2-1-3 are arranged between the shielding top plate 2-1-2 and the connecting outer wall 2-1-4, an air inlet is formed between the plurality of partition bars 2-1-3, and a partition bar is arranged on the air intake valve top cover to form an air inlet, and external air can enter the head cover from the air inlet.

[0027] To be more specific, the air intake valve base 2-2 includes a base bottom plate 2-2-1, which is also an annular structure, and a connecting inner wall 2-2-5 is arranged on the middle edge, and a plurality of support plates 2-2-2 are arranged in the connecting inner wall 2-2-5. The plurality of connecting support plates 2-2-2 are arranged in a radial shape, and a fixing plate 2-2-6 is arranged at the central connection of the connecting support plates 2-2-2, and a fixing column 2-2-3 is arranged at the center of the fixing plate 2-2-6. A plurality of support plates are arranged on the air intake valve base to limit the air intake diaphragm. When exhaling, the airflow presses the air intake diaphragm to fit onto the support plate, preventing the entry of external air and realizing one-way air intake. When inhaling, the air intake diaphragm is no longer constrained and can be partially separated from the air intake valve base, and external air enters the head cover through the air intake valve base.

[0028] To be more specific, a fixing hole 2-3-1 is provided at the center of the air intake diaphragm 2-3, and the fixing hole 2-3-1 is interference fit with the fixing column 2-2-3. In this embodiment, a fixing hole is provided on the air intake diaphragm and is interference fit with the fixing column, so that during the air intake process, the middle part of the air intake diaphragm is fixed and the edge is sucked up, and it will not be separated from the air intake valve base as a whole, thereby ensuring a one-way air intake effect.

[0029] To be more specific, the top of the connecting inner wall 2-2-5 is sunken to form a diaphragm placement groove 2-2-4, the diaphragm placement groove 2-2-4 is flush with the surface of the connecting support plate 2-2-2, and the diaphragm placement groove 2-2-4 matches the air intake diaphragm 2-3.

The setting of the breathing holes can ensure that external air can be smoothly inhaled, thereby ensuring smooth breathing.

[0031] To be more specific, the facial covering layer 1-1 is provided with a Velcro 4 at the lower jaw position. By providing the Velcro at the lower jaw position of the facial covering layer to adhere to the inner lining of the helmet, the headgear is fixed and a larger breathing space is formed under the mouth and nose of the facial covering layer. The facial covering layer will not fit too closely to the mouth and nose, thereby obtaining a better breathing effect.

[0032] More specifically, the head cover 1 also includes a neck covering layer 1-2, and the neck covering layer 1-2 is laterally symmetrically provided with helmet fixing buckle through holes 1-2-1. Two helmet fixing buckle through holes are provided at the neck covering layer, and the fixing buckles can be inserted through the holes after the helmet is worn, so as to further fix the head cover and prevent the exhaled waste gas from being unable to be discharged smoothly when the neck covering layer is compressed from the outside.

[0033] The working principle of the utility model is as follows: after the head cover is worn, the flexible support strip 3 is squeezed so that the flexible support strip 3 fits against the bridge of the nose and the face, thereby preventing the hot air exhaled from the mouth and nose from rising to the visual area 1-5, thereby achieving the effect of preventing fogging at the helmet goggles. At the same time, when the head cover 1 is worn, the Velcro 4 is adhered to the inner lining of the helmet, so that the breathing area 1-3 is pulled up to a certain angle, and breathing is smoother. The fixing buckle of the helmet is passed through the hole 1-2-1 of the helmet fixing buckle to fix the helmet. When breathing, the air can enter the one-way air inlet valve 2 through the breathing hole 1-3-1, and the exhaled air is discharged from the bottom of the head cover 1.
