What the claims cover, in plain language

Claim 1 - defines a mirror cabinet with a drying mechanism comprising a mounting plate, a hanging shaft, and an inner roller shaft. Key elements include two squeeze rollers positioned on either side of the inner shaft, driven by a first power mechanism for rotation and a second for lateral movement. The inner shaft has a water suction pipe with holes. The squeeze rollers have air supply shafts with jet holes. Sliding blocks connect the rollers to the second power mechanism. The mechanism is actuated by the closing of the cabinet door via push rods, gears, and a lifting assembly.

Claim 2 - specifies a vacuum pump connected to the water suction pipe to enhance moisture extraction. Claim 3 - describes tangential structures forming a water suction cavity between the pipe and the inner wall of the roller shaft. Claim 4 - adds a steam generator communicating with the air supply shafts of the squeeze rollers. Claim 5 - details the transmission assembly using gears with spiral grooves and bayonet locks to convert linear motion into rotational/lifting actions. Claims 6-8 - further refine the bracket structures, spring mechanisms, and bayonet configurations used in the lifting assembly.

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 or selling this specific configuration in China requires the owner’s permission. There is no corresponding US patent application or granted patent in the family.

Two points to settle early:

  • Other patents may exist. Bathroom fixtures with drying functions, particularly those involving steam, heat exchange, or automated mechanical gripping, are subject to various existing patents in the US market. A freedom-to-operate (FTO) review is recommended to ensure the integration of vacuum suction and steam spraying does not infringe on prior art regarding towel warmer technologies or automated cabinet mechanisms.
  • Electrical Safety Certification. Because the device combines water handling (suction/steam) with electrical components (pumps, heaters, motors) in a humid environment, strict adherence to US electrical safety standards is critical.

Customization and manufacturing

What can be customized

AreaOptions
Cabinet SizeWidths from 24 to 48 inches; depth adjusted for towel volume.
FinishMirrored doors, matte black, brushed nickel, or white powder coat.
Control InterfaceTouch panel, remote control, or simple door-triggered automation.
Heating ElementElectric heating vs. steam generation capacity adjustments.
Roller MaterialSilicone, stainless steel, or plastic composites for grip and durability.
LightingIntegrated LED strips around the mirror for ambient lighting.

Things to plan for (US market)

  • UL 1598 / UL 1993 - Standard for luminaires and lamps; applies if the mirror cabinet includes integrated lighting.
  • NEC (National Electrical Code) - General requirements for electrical installations in damp/wet locations (bathrooms).
  • ASME A112.18.1 / CSA B125.1 - Plumbing fixture performance standards, relevant if the unit connects to water lines for steam generation.
  • California Prop 65 - Screening for chemicals in plastics, coatings, and solder used in manufacturing.

How a project runs

  1. Inquiry - Define cabinet dimensions, drying capacity, and aesthetic preferences.
  2. Design - Engineer the mounting plate, roller alignment, and fluid channels (water/steam).
  3. Prototype - Build functional samples to test suction efficiency and steam distribution.
  4. Pilot Run - Validate durability of moving parts and seal integrity under humidity.
  5. Production - Injection molding for rollers/plastics, metal fabrication for frames, assembly of electronic modules.

Quantities & timeline

Tooling for the custom mirror cabinet frame and injection molds for the roller assemblies and internal housings will dictate the initial lead time. Certification testing for electrical safety and steam components typically takes 4-6 weeks. Send us your desired cabinet dimensions, finish options, quantity estimates, and target launch date and we will reply with options.
