What the claims cover, in plain language

Claim 1 - a hair straightener with an upper arm and a hinged lower arm. The upper arm has a handle part and a jaw that is twisted by an angle α relative to the handle; the lower arm has a matching handle part and jaw; a PCB sits in one of the arms.

Claim 2 - the angle α is 45-75°. Claims 3-6 - each handle part is a housing and cover (with buttons on the upper one); each jaw has a heater wired to the PCB and an aluminum plate that touches the hair. Claim 7 - a curling groove in the lower jaw. Claims 8-9 - press tips at the jaw ends with rubber sleeves.

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. It is still in force in China, so making or selling this design in China would need the owner’s permission while it lasts (at most until 2026-11-15). It has no US or other foreign counterpart and does not restrict the design outside China.

Before production, keep in mind:

  • Other patents may exist. Hair-styling tools are a crowded field with many US patents held by large brands. Use your own styling and have a freedom-to-operate (FTO) search done by a US patent attorney before volume production.

Customization and manufacturing

What can be customized

AreaOptions
AngleWithin 45-75° - to be confirmed with user testing
PlatesAluminum, ceramic-coated or titanium; plate width
HeatingPTC or MCH heaters; temperature range and display
Voltage120 V US, or dual voltage for travel
SafetyAuto shut-off, swivel cord, heat-resistant tip caps
Colors & brandingBrand colors, soft-touch finishes, gift packaging

Things to plan for (US market)

  • Electrical safety - a mains hair appliance needs safety certification (for example UL 859 / ETL) for most US retailers.
  • FCC - digital control boards may need FCC Part 15 compliance.
  • Hot-surface warnings - required labels and instructions; consider auto shut-off.

How a project runs

  1. Inquiry - plate type, temperature range, voltage and quantity.
  2. Design - angle, housing, heater and PCB.
  3. Prototype - samples for heating, ergonomics and safety tests.
  4. Pilot run - small batch to check assembly and certification samples.
  5. Production - volume production, packaging and shipping.

Quantities & timeline

Housings are injection-molded; heaters, plates and PCB are standard appliance parts adapted to the angled jaws. Safety certification is planned before mass production. Send us your specification, quantity and target price and we will reply with options.
