Definitions

  • the present disclosure relates to a hair dryer especially for drying hair.
  • CN104783472A discloses a strong magnetic attraction type automatic head-oscillatable hair dryer.
  • CN203087949U discloses a rotary hair dryer.
  • CN208581919U discloses a hair dryer bracket with an oscillation function.
  • CN104621944A discloses a suction cup type safety hair dryer.
  • US 1,716,580 discloses an hair dryer which can be attached to an electric vacuum cleaner.
  • the hair dryer has a pivotable leg and a pair of supports.
  • DE 29 51 562 discloses an hair dryer with a protruding handle portion.
  • Another hair dryer is disclosed in DE 20 2013 001 172 U1 .
  • An object of the present disclosure is to provide a hair dryer which is capable of conveniently achieving switch between a hand-held operation mode and a hands-free operation mode.
  • a hair dryer having the features of claim 1.
  • a hair dryer which comprises a body and a holder or holding mechanism connected thereto, wherein the holder is configured to be reversibly convertible from a handle configuration to a support configuration via its own metamorphosis in shape. This fast conversion idea enables convenient switching of the hair dryer between a hand-held operation mode and a hands-free operation mode.
  • metalamorphosis in shape of the holder on its own means the shape change or transformation of the holder by itself, and does not include the following case: the holder does not substantively change in the structure and shape, and only changes in position relative to the body of the hair dryer, for example, in pivotal positions.
  • the holder has a connecting end connected to the body and an opposite free end (non-connecting end).
  • the free end of the holder is configured to be expandable in shape so as to enlarge its support footprint(s). With the free end being expanded, the holder may quickly switch or transform from an initial handle to a fixing support, and thus the hair dryer being conveniently switched to perform the hands-free air blowing operation.
  • the holder may include more than one wing (preferably 2-4 wings, for example three wings) encircling its free end so that the holder acts as the handle when the wings do not flare out and acts as the support when the wings flare out.
  • a holder is structurally simple and can very conveniently achieve the air blowing mode switch or transformation.
  • a fixing seat or fixing disc may be fast connected to (e.g., plugged into) the free end of the holder, or even an expandable supporting disc or support webs may be ejected or pulled out of the free end, use of the "open-umbrella" variation or modification of the present disclosure is obviously more advantageous in structural integration or convenience in use.
  • the distal ends (flarable ends) of the wings may be disposed at the free end of the holder and flare outwardly 0-90° therefrom ("forwardly open” mode); or the proximal ends (connecting and fixing ends) of the wings may be disposed at the free end of the holder so that the distal ends of the wings may flare outwardly or flip 90-180°towards the free end of the holder ("reversely open” mode).
  • the "forwardly open” mode structure is simpler and more convenient to operate; however, the “reversely open” mode structure may enable the holder to extend longer or higher (within a range approximate to the length of the wings) so as to adjust the air blowing height.
  • the body of the hair dryer may be integrally formed with a hollow handle in a way that the holder of the present disclosure may be received in the hollow handle and be pulled and ejected out of the hollow handle.
  • the transformation of the holder to the handle may be implemented by receiving the holder in the hollow handle; the transformation from the handle to the fixing support may be implemented by pulling the holder out of the hollow handle and making its free end expand.
  • the distal ends of the wings may substantially be in the same supporting surface (horizon) as the free end of the holder. Such a structure makes the support firmer.
  • the free end of the holder may be provided with a suction cup or friction pad.
  • the free ends of the wings may also be provided with a friction pad respectively. Such a structure may further enhance the support stability.
  • the holder is telescopic in its longitudinal direction, for example, the holder is configured as a telescopic sleeve or a multi-stage antenna structure.
  • a telescopic sleeve may be designed to be adjusted in its telescopic length and be retained or fixed at any length position; or may be designed as a multi-stage positioning sleeve so that it can be retained or fixed at different set length positions.
  • the holder is movably connected to the body of the hair dryer.
  • the movable connection manner facilitates adjustment of the air blowing angle and air blowing direction.
  • the body of the hair dryer is relative to the holder and comprises a housing, parts located in the housing and various stationary accessories disposed on the housing.
  • the above movable connection may either be a separable or detachable connection or an inseparable or undetachable connection. However only detachable connections are covered by the present invention.
  • the holder may be connected to the body of the hair dryer via a hinge.
  • the pivotal connection manner not only enables the holder to conveniently adjust the air blowing angle when the holder is used as the support, but also enables the holder to be folded towards the body for purpose of convenient carrying or enables the holder to be received at a proper position of the body to facilitate storage.
  • the hinge may be such a hinge that can be positioned at any pivot angle, i.e., can be arbitrarily pivoted and stay or be fixed at a current pivot position.
  • the hinge may be a multi-stage positioning hinge that can be pivoted and positioned at different set angles.
  • the hinge may be further fixed to a rotatable shaft disposed on the holder.
  • a rotatable shaft disposed on the holder.
  • Such a structure may cater to adjustment of the air blowing angle as well as the air blowing direction.
  • the rotatable shaft may be rotated to stay or be fixed at an arbitrary current orientation; or may be fixed at different set orientations.
  • the holder may be connected to the body of the hair dryer via a magnetic coupling.
  • the coupling consists of an iron ball disposed on one of the body and the holder and a socket including a ring magnet disposed on the other of the body and the holder for magnetically receiving the iron ball therein.
  • a movable connection is simpler in structure, not only enables adjustment of the air blowing angle and air blowing direction when the holder is used as a support, but also facilitate fast separation of the holder from the body of the hair dryer, and facilitates the carrying and storage.
  • the magnetic coupling is not limited to a specific combined structure of the iron ball and the ring magnet, and any suitable magnetic coupling connection is feasible: for example, a ferromagnetic member-magnet combination or a magnet-magnet combination.
  • the holder may also be connected to the body of the hair dryer via a freely-deformable rope (flexible rope).
  • a freely-deformable rope flexible rope
  • Such structure may also achieve multi adjustments of the air blowing angle, air blowing direction and air blowing height.
  • the holder may be connected to the body of the hair dryer via a friction ball mechanism.
  • the friction ball mechanism may comprise a receptacle, a rotatable ball and a friction pad, and the ball is undetachably received in the receptacle under a tight fit through the friction pad encircling the ball (the holder, under action of an external force against the friction force, can rotate in any direction and stay at a current position when the external force is removed).
  • the receptacle may be disposed on one of the body and the holder, and the ball may be connected to the other of the body and the holder via a connecting rod.

  • the rear tube part may be removably or detachably connected to the front operational tube part, such that the hair dryer becomes light and handy when in use by removal of the rear tube part.
  • Such a single tube configuration makes the hair dryer of the present disclosure look very brief, neat and beautiful when in a not-in-use state, for example, when the hair dryer is stored, minimizes the occupied space and eliminates the trouble caused by the messy power supply line.
  • the hair dryer of the present disclosure may further comprise a cover which is used to at least cover a rear end of the rear tube part when the power supply line is received in a chamber of the rear tube part.
  • the holder may be connected to a side of the body of the hair dryer.
