What the claims cover, in plain language
Claim 1 describes a smart sun hat comprising a visor, a hat band, a central control mechanism, and a cooling mechanism. The visor is in the middle of the hat band, and both the control and cooling mechanisms are mounted on it and electrically connected. The cooling mechanism has a horizontal moving assembly, an angle adjusting assembly, and a cooling assembly. The cooling assembly uses a third motor with blades arranged uniformly around its shaft. The angle adjusting assembly includes a fixing plate, a second motor, a second driving shaft, and a connecting rod. The second motor is below the fixing plate and drives the connecting rod, which is hinged to the shaft at one end and to the lower half of the third motor at the other. The central control mechanism includes a panel, a solar cell panel, a display interface, a control key, status indicator lamps, and a PLC central control module inside the panel. The PLC connects to a motor control module, wireless communication module, electric energy acquisition module, display control module, key control module, state indication module, and working power supply module. The working power supply circuit uses an NE555 integrated circuit, diodes, resistors, capacitors, a light emitting diode, and a field effect transistor to regulate voltage by collecting and feeding back the output voltage to control the transistor.
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 there (until at most 2037-02-18, provided annual fees are paid). Making or selling this specific design in China needs the owner’s permission. It has no US or other foreign counterpart.
Two points to settle early:
- Other patents may exist. Wearable cooling devices, solar-powered headwear, and portable fans are active fields with many US and international patents held by various consumer electronics and apparel companies, so a freedom-to-operate (FTO) review of the motorized angle adjustment, horizontal movement, and solar-power circuit is needed before tooling.
- Component integration. Mounting motors, a PLC, and a solar panel on a fabric or plastic visor requires careful weight distribution and structural planning to ensure the hat remains comfortable and balanced on the head.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Hat material | Cotton, polyester, nylon, straw blends, or EVA foam for the visor |
| Fan blades | Number, pitch, and material (plastic or silicone) set in design / confirmed on prototypes |
| Solar panel | Size, efficiency rating, and flexibility to match the visor curve |
| Control interface | Button layout, display type (LCD/LED), and indicator lamp colors |
| Battery backup | Capacity and placement (e.g., in the hat band) to be confirmed in design |
| Wireless module | Bluetooth protocol version for app connectivity |
| Colors and branding | Fabric dyeing, screen printing, or embroidered logos |
Things to plan for (US market)
- FCC Part 15 - the wireless communication module emits radio frequencies and must be tested and certified for sale in the US.
- UN 38.3 and UL 2054 - the patent places a storage battery inside the panel; if lithium cells are used, the cells and pack need transport testing and pack safety certification.
- California Proposition 65 - plastics, solder, and battery components must be screened for restricted chemicals.
- Fan blade guarding - the fan blades sit close to the head and face, so a finger-probe check and guard design are confirmed on prototypes.
How a project runs
- Inquiry - target audience, feature list, materials, and quantity.
- Design - CAD modeling of the visor, motor mounts, PCB layout for the NE555 circuit, and PLC programming.
- Prototype - 3D-printed housings and assembled samples to test fan angle, noise, weight balance, and solar charging.
- Pilot run - small batch for FCC pre-compliance testing, wear trials, and thermal checks on the power circuit.
- Production - injection molding for housings, PCB assembly, textile cutting and sewing, final integration, and quality inspection.
Quantities & timeline
The project requires injection molds for the motor housings and fixing plates, custom PCB fabrication for the NE555 power circuit and PLC modules, and textile dies for the hat band and visor. Certification tests for the wireless module and battery take additional time. Send us your target specs, preferred materials, feature requirements, quantity and timeline and we will reply with options.
