Patent CN112189973B
Updated November 1, 2026Motorized Hair Dryer Holder with Retractable Cord and Rope
Standard hair dryer hooks leave cords dangling, leading to tangles, electrical strain, and moisture trapping at the handle base. This motorized mount solves this by integrating a dual-station winding reel. One station manages the power line, the other a support rope connected to the dryer. When you pull the dryer down, the reel extends; when you release it, the motor or spring mechanism retracts both the cord and the rope, lifting the dryer back into its protective housing. The design minimizes cable stress and keeps the unit dry by reducing static contact points where humidity accumulates.

The problem
Traditional hair dryer mounts are simple hooks or shelves. They hold the device but leave the long power cord exposed. Over time, dangling cords create tangles, suffer from repeated bending near the plug, and can collect dust or moisture. In humid bathrooms, a stationary dryer resting on a hook often traps condensation around the handle and vents, which can lead to electrical leakage or short circuits over years of use. Additionally, heavy or expensive dryers risk falling if the hook is not perfectly sized, causing impact damage to the device or the user.
The solution
This patent describes a specialized support bin that houses a mechanical winding system. The core component is a winding reel located inside a storage bin. This reel has two distinct stations. One station winds a driving rope, which connects directly to the hair dryer body. The other station winds the power line of the dryer itself.
The reel is mounted on a rotating shaft secured by a first locking assembly. A coil spring provides the force to reset the reel to its initial position. To control movement, a drive assembly consisting of a motor and gears interacts with the reel. When the user pulls the dryer, the mechanism unlocks and allows extension. When released, the spring and motor coordination retract the rope and cord, pulling the dryer back into the safety of the bin. A silicone cushion inside the bin absorbs impact, protecting the dryer.

Who it is for
- Hotel and Hospitality Suppliers: Seeking durable, self-cleaning bathroom amenities that reduce maintenance labor for tangled cords.
- Smart Bathroom Brands: Integrating motorized accessories into modern home automation setups.
- Salon Equipment Manufacturers: Needing organized tool holders that keep cords off the floor and away from water sources.
- High-End Residential Builders: Installing premium fixtures that offer aesthetic cleanliness and safety features for wet areas.
How it works
The main parts
The system relies on precise mechanical interlocking to function safely. The drawings detail the internal arrangement of the reels, springs, and locking blocks.
| No. | Part | What it does |
|---|---|---|
| 1 | Storage Bin | Houses all components; has a horn-shaped opening for insertion. |
| 2 | Winding Reel | Rotates inside the bin; has two stations for cord and rope. |
| 3 | Coil Spring | Provides torque to retract the reel to the starting position. |
| 4 | Driving Rope | Connects the dryer to the reel; winds on one station. |
| 5 | Hair Dryer | The device being stored and supported. |
| 6 | Rotating Shaft | Axis for the reel; secured by locking assemblies. |
| 7, 8, 9 | First Locking Assembly | Shell, block, and cover plate; secures the shaft. |
| 10 | Driving Motor | Powers the extension/retraction assist. |
| 12 | Driving Wheel | Engages with the reel; includes brake parts. |
| 15 | Positioning Rod | Moves vertically to engage locking states. |
| 28 | Silicone Cushion | Lines the storage area to prevent impact damage. |

Operating Steps
- Insertion: The user places the hair dryer into the horn-shaped storage opening. The driving rope attaches to the dryer.
- Extension: To use the dryer, the user pulls it downward. The positioning rod moves out of the locked state, allowing the driving wheel to disengage the brake. The motor may assist or the user manually unwinds the rope and power cord from their respective stations on the reel.
- Usage: The dryer hangs freely on the rope, with the cord managed by the reel, preventing tangling.
- Retraction: Upon releasing the dryer, the first locking assembly engages. The coil spring drives the reel to rotate backward. The driving rope and power line wind up simultaneously.
- Storage: The dryer is pulled back into the bin, resting against the silicone cushion. The locking assembly secures the shaft, holding the dryer firmly in place.

Applications
Hotel Bathrooms
Guests do not need to wrap cords themselves. The auto-retraction keeps the vanity area clean and reduces housekeeping time spent untangling cables.
Home Master Suites
For users with high-end dryers, this mount prevents accidental drops and protects the device’s finish from scratches against hard surfaces.
Beauty Salons
Stylists need quick access to tools without stepping over cords. The suspended rope keeps the dryer at hand height while the cord remains coiled and safe.
Elderly Care Facilities
Reduces the physical effort required to lift and store heavy devices. The guided motion helps prevent wrist strain associated with traditional hanging hooks.
Where it is less suitable
- Portable Travel Dryers: These units are too light and small to trigger the tension mechanisms effectively.
- Non-Cordless Mains Appliances: The weight and cord thickness must match the specific reel capacity designed for standard hair dryers.
Frequently asked questions
How does the cord retraction work?
The system uses a central winding reel with two separate stations. One station holds the power cord, and the other holds a support rope attached to the dryer. A coil spring provides the tension to pull them back in when you release the dryer. An optional motor assists with smooth extension and controlled retraction speed.
Will it fit my specific hair dryer?
The patent describes a general mechanism, but compatibility depends on the weight and cord length of your dryer. The silicone cushion and rope attachment point can be adjusted in design to accommodate different handle shapes and sizes. We recommend checking the maximum load rating during the prototype phase.
Does it help with moisture issues?
According to the patent, the design aims to reduce the phenomenon of vapor adsorbing at the hair-dryer handle position. By retracting the dryer into a protected bin and minimizing static contact points where water might pool, it lowers the risk of electrical leakage caused by long-term moisture exposure.
Is the motor loud?
The patent mentions a driving motor and gear assembly. Noise levels depend on the specific motor chosen and the lubrication of the gears. For hotel applications, quiet-running DC motors with sound-dampening housings are typically specified.
Can I install it myself?
Installation involves mounting the storage bin securely to the wall. Since it contains a motor and handles an electrical cord, professional installation is recommended to ensure proper anchoring and electrical safety compliance. The patent shows a standard bin structure adaptable to various wall types.
What happens if the power goes out?
The primary retraction force comes from the coil spring, not just the motor. Therefore, even without electricity, the spring should still pull the dryer back into the holder, though the assisted extension feature would be inactive.
Can this design be made and sold in the US?
The patent is active in China but has no US counterparts. You can manufacture and sell this design in the US without infringing this specific patent. However, because it involves electrical components and mechanical retraction, a freedom-to-operate search is advised to ensure no other US patents cover similar motorized cord management systems.
