What the claims cover, in plain language
Claim 1 defines an anti-mosquito hat comprising a cap body and a brim. Key features include an annular chute on the brim, horizontal holes in the cap body, and a gear rotating ring sleeved on the outside. The ring connects to arc-shaped connecting plates and second arc-shaped plates, linked by connecting rods passing through the holes. Inside, arc-shaped contact pads press against the head. Multiple gear plates mesh with the ring externally, pushed by a first spring group housed in a groove on a first fixing block on the brim.
Claim 2 adds a double-layer gauze net attached to the brim bottom. It includes a horizontal plate, through holes in the brim, an abutting plate, and a second fixing block. A connecting cloth runs through the holes, topped by a baffle plate. Clamping plates on the cloth engage with a clamping block on a transverse rod inside the second fixing block, secured by a second spring group.
Claims 3-7 detail specific placements of the clamping plates, the equidistant arrangement of the net connection, and the specific geometry of the gear ring bottom within the chute.
This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.
What this means for US production
This patent was filed only in China and is currently in force. Making, selling, or importing products falling strictly within these claims into the United States does not infringe this specific Chinese patent, as patents are territorial. However, since there are no corresponding US patents, the design is not protected in the US market by this document alone.
Two points to settle early:
- Other patents may exist. Headwear and insect protection devices are crowded fields. While this specific gear-ring mechanism appears unique to this filing, you must conduct a freedom-to-operate (FTO) review to ensure no existing US patents cover similar mechanical sizing systems or net attachment methods.
- Complexity vs. Cost. The multi-part assembly (rings, springs, plates, rods) increases manufacturing complexity compared to standard elastic-band hats. Tooling costs for the small plastic/metal components will be higher.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Materials | Cap body: Nylon, polyester, or cotton blend. Gear/Ring: ABS plastic, POM, or stainless steel. |
| Colors | Camouflage patterns (green, brown, digital), solid colors (black, navy, khaki). |
| Net Type | Single layer vs. double layer; mesh density (fine for gnats, coarse for bees); color (black for contrast, white for heat reflection). |
| Size Range | Adjusted by varying the stroke length of the contact pads and the number of gear teeth. |
| Brim Style | Wide brim for sun protection vs. narrow brim for compactness. |
| Features | Add ventilation slots in the cap body; integrate a chin cord storage loop. |
Things to plan for (US market)
- Consumer Product Safety Commission (CPSC): General safety requirements apply. Ensure small parts (springs, pins) are durable and do not detach easily if marketed near children, though this is primarily an adult fishing item.
- Textile Flammability: Standard 16 CFR 1610 applies to clothing and accessories made of textile materials.
- Labeling: Care labels and country of origin marking (“Made in China”) are required for import.
- No FDA/Medical Claims: Do not market as preventing diseases (e.g., malaria, Zika) unless registered as a pesticide-treated article, which requires EPA registration for treated fabrics. Stick to “mechanical barrier” descriptions.
How a project runs
- Inquiry - Specify target price, material preferences, and quantity.
- Design - Finalize gear tooth profile, spring rates, and net attachment geometry.
- Prototype - 3D print mechanical parts; sew sample nets; test fit and durability.
- Tooling - Create injection molds for the gear ring, plates, and blocks; stamping dies for metal components if used.
- Production - Injection molding, sewing, assembly of mechanical parts, quality control.
Quantities & timeline
The mechanical nature of this hat requires precise tolerances for the gear meshing to work smoothly. Molds for the small plastic components are intricate. Assembly involves inserting springs and aligning rods, which may slow down line speed compared to simple caps.
