[0033] like Figures 2-4 As shown, this embodiment provides a dual-channel anti-fogging headgear, including...

[0034] The headgear body 1 isolates the head from the external environment. The headgear body 1 is provided with an observation port for observing external objects, and a ventilation port is provided below the observation port.

[0035] A breathing device 3 is provided, which covers the area near the user's nasal cavity. The breathing device 3 includes a housing 31, an air inlet, an air inlet valve 32, an air outlet 33, and an air outlet pipe 34. The housing 31 is connected to the inside of the headgear body 1 and has a cavity sufficient to accommodate the nasal cavity. The air inlet is located on the housing 31 and corresponds to the air vent. The air inlet valve 32 is located at the air inlet. The air outlet 33 is located on the outside of the headgear body 1. The air outlet pipe 34 connects the cavity and the air outlet 33.

[0036] Specifically, the vent is a small round hole located directly in front of the headgear body 1, which is just large enough to accommodate an air intake valve 32. The air intake valve 32 only allows air in and does not exhaust air. The air inlet is located directly in front of the outer shell 31, and its position corresponds to the vent, just below the nasal cavity.

[0037] In the specific production process, see Figure 2 The air inlet valve 32 must be connected to the air vent on the headgear body 1 to ensure that air does not enter the gap between the headgear body 1 and the breathing device 3.

[0038] During use, air enters the headgear body 1 through the air inlet valve 32 and is then discharged through the air outlet 33, ensuring that the headgear body 1 is always in a state of air circulation.

[0039] This utility model discloses a dual-channel anti-fogging headgear, which is equipped with a breathing device 3. The breathing device 3 includes a shell 31, an air inlet, an air inlet valve 32, an air outlet 33, and an air outlet pipe 34. In use, air enters through the air inlet, and the air inlet valve 32 prevents air from escaping through the air inlet, while the air is exhausted through the air outlet 33. The air inlet and outlet are provided with separate channels. Compared with the single channel in the prior art, the dual-channel anti-fogging headgear of this utility model allows for smoother air exhaust and better air quality inside the headgear.

[0040] In an optional embodiment, the headgear body 1 is made of a flexible material, such as cotton, linen, polyester fiber, rubber, etc. In this embodiment, polyester fiber is preferred because it has a low manufacturing cost and is easy to obtain. With the flexible material of the headgear body 1, it does not take up much space and is easy to carry.

[0041] In an optional embodiment, a goggle 2 is provided on the observation port to prevent wind from blowing directly into the eyes during movement.

[0042] In an optional embodiment, both the outer shell 31 and the air outlet pipe 34 are made of silicone material, which is soft and comfortable to the touch, durable, and easy to clean.

[0043] In an optional embodiment, the outer shell 31 is bonded to the inside of the headgear body 1, and the bonding method is easy to manufacture.

[0044] In an optional embodiment, the outer shell 31 is narrower at the top and wider at the bottom, with the inner ring of the outer shell 31 fitting close to the nasal cavity and around the lips. The design of being narrower at the top and wider at the bottom fits the face better and is more comfortable to wear.

[0045] In an optional embodiment, the inner ring of the outer casing 31 has an inwardly snapping structure; specifically, see [link to relevant documentation]. Figure 3 The inner ring of the outer shell 31 has an inwardly curved, buckled structure, which provides better airtightness.

[0046] In an optional embodiment, the opening of the air outlet 33 faces the ground.

[0047] In an optional embodiment, the headgear body 1 is provided with filter cotton. By providing filter cotton, the incoming air is first filtered to ensure air quality.

[0048] In an optional embodiment, the headgear body is provided with a layer, and the filter cotton is placed in the layer; the specific layer is not shown in the figure. The layer is similar to a pocket design, in which the filter cotton is placed for filtration. The design of the layer allows the filter cotton to be replaced at any time.

[0049] Working Principle: This utility model discloses a dual-channel anti-fogging headgear. During operation, the headgear body 1 is first worn on the head, completely covering the head. The position of the breathing device 3 is adjusted so that it fits snugly against the nasal cavity and around the lips. During breathing, air is first filtered through a filter cotton, then passes through the air inlet valve 32 into the headgear body 1. Since the air inlet valve 32 only has a one-way air intake function, air can only be discharged through the air outlet 33 at the bottom via the air outlet pipe 34. This utility model's dual-channel anti-fogging headgear prevents fogging, ensures smoother air discharge, and results in better air quality inside the headgear.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
