Multi-Purpose Hair Curler with Straight-Roll Comb and Anti-Scald Teeth

The problem

Most hair styling requires two separate tools: a flat iron for straightening and a wand or tong for curling. Switching between tools increases handling time and exposes hair to repeated heat application, which can cause damage. Additionally, standard curling wands lack a guide mechanism to keep hair strands aligned, often resulting in uneven curls or accidental contact with hot barrels. Users need a compact solution that performs both functions smoothly while minimizing the risk of burns to the scalp or fingers when manipulating the hair near the heating elements.

The solution

The patent describes a multi-purpose hair curler that combines straightening and curling capabilities in a single handheld unit. The device consists of a handle (300), a lower plate (200) fixed to the handle, and an upper plate (100) rotatably assembled with the handle.

1. The lower plate contains a straightening plate (210) for smoothing hair.
2. The upper plate contains a curling plate for shaping hair.
3. A resetting means, specifically a torsion spring, is positioned between the upper plate and the handle to ensure the jaws close or open to a default position automatically.
4. At the end of the upper plate, opposite the lower plate, are anti-scald comb teeth (110).
5. These teeth are composed of two materials: plastic anti-scald comb teeth and aluminum alloy comb teeth.
6. The plastic teeth are taller than the aluminum teeth and are arranged in a staggered pattern between rows of aluminum teeth.
7. A switch (310) on the handle controls the temperature of both plates.
8. A power supply line (320) connects to the end of the handle.

Who it is for

• Personal Care Brands: Companies looking to expand their hair styling portfolio with a dual-function appliance that reduces SKU complexity.
• Amazon Sellers: E-commerce vendors seeking a differentiated product with clear safety features (anti-scald teeth) to appeal to home users.
• Salon Equipment Suppliers: Distributors who provide professional-grade tools that offer versatility for stylists working on mixed-texture hair.
• Travel Accessories Makers: Brands focusing on compact grooming solutions where space-saving multi-tools are preferred over bulky separate devices.

How it works

The main parts

Operating steps

1. Power On: Plug in the device and use the switch (310) to set the desired temperature for the curling and straightening plates.
2. Straighten: Open the upper plate (100) away from the lower plate (200). Place hair between the plates and clamp down to smooth strands using the heated straightening plate (210).
3. Curl: Rotate the handle or adjust the angle to bring the upper plate’s curling surface into contact with the hair. Wrap or glide the hair along the curling plate.
4. Comb Guide: As the hair moves toward the tip, it passes through the anti-scald comb teeth (110). The taller plastic teeth guide the hair and protect the scalp, while the shorter aluminum teeth assist in heat transfer or alignment.
5. Reset: Release the tension on the handle; the torsion spring returns the upper plate to its resting position.

Applications

Home Hair Styling

Users can achieve both sleek straight looks and defined curls with a single tool, reducing the need to purchase and store multiple appliances. The anti-scald teeth make it safer for beginners to handle hair near the hot surfaces.

Travel Grooming

The integrated design saves luggage space compared to carrying a separate flat iron and curling wand. The sturdy construction and protective teeth minimize damage to other items in a bag.

Professional Salon Use

Stylists can quickly switch between straightening sections and curling ends without changing tools, speeding up service times for clients requesting mixed styles.

Quick Touch-Ups

For morning routines, users can straighten frizzy roots and curl the ends in one pass. The comb teeth help detangle and guide hair simultaneously, preventing knots during styling.

Where it is less suitable

• Very Long Thick Hair: Standard barrel sizes may not accommodate extremely thick bundles efficiently compared to dedicated high-capacity tools.
• High Heat Precision Needs: While adjustable, this multi-tool may not offer the precise temperature zones of specialized professional irons.
• Cordless Requirements: The design explicitly includes a power supply line, making it unsuitable for users requiring battery-operated portability.
