One end of an elongate flexible tubular hose is coupled to the cap. The other end of the hose is coupled to a blower housing. At least one heating element is mounted in the blower housing. A battery power source is mounted in the blower housing and is electrically connected to the heating element. A fan is mounted in the housing and is electrically connected to the battery power source. An elongate flexible belt is coupled to the blower housing.

In closer detail, the hairdryer 10 includes a flexible cap 11 designed for wear on the head of a user such that the hair of the user is covered by the cap. The cap has spaced apart and generally coextensive inner and outer layers 12,13, and an opening 14 therein designed for receiving the head of a user therein. The opening of the cap has an generally circular outer periphery where the inner and outer layers are coupled together therearound. The cap preferably has an elastic head band 15 around the outer periphery of the opening of the cap for helping hold the cap on the head of the user.

The inner and outer layers of the cap each have a plurality of apertures 16,17 therethrough. The apertures of the inner layer are designed for permitting the passage of air therethrough to dry the hair of the user. In use, the apertures of the outer layer are designed for permitting the passage of exhaust air therethrough to keep the cap from becoming too inflated. The apertures of the inner and outer layers of the cap each are generally circular and each have a diameter. The diameter of each of the apertures of the inner layer of the cap is preferably greater than the diameter of each of the apertures of the outer layer of the cap.

The apertures of the inner layer of the cap are preferably arranged in groups of three on the inner layer of the cap. Each group of apertures of the inner layer is spaced apart from the other groups of apertures of the inner layer for providing even distribution of air to the head of a user and permitting sufficient air to pass to the head of the user. Similarly, the apertures of the outer layer of the cap are preferably arranged in groups of three on the outer layer of the cap. Each group of apertures of the outer layer is spaced apart from the other groups of apertures of the outer layer.

An elongate flexible tubular hose 18 having is provided a pair of opposite ends. The tubular hose preferably has a plurality of spaced apart annular constrictions 19 therearound. The annular constrictions of the hose are arranged in a row along the hose extending between the ends of the hose. Ideally, the annular constrictions of the hose are spaced apart at generally equal intervals in the row of annular constrictions. In use, the annular constrictions are designed for enhancing the flexibility and compression of the hose for convenient storage while providing optimal strength to the hose.

A first of the ends of the hose is coupled to the cap to fluidly connect the hose to the space between the inner and outer layers of the cap. A generally rectangular-box-shaped blower housing 20 is provided having a plurality of generally rectangular faces. A second of the ends of the hose is coupled to a first face of the blower housing to fluidly connect the hose to the interior of the blower housing.

First and second heating elements 21,22 are mounted in the blower housing. The first and second heating elements provide heat when energized to heat the air in the blower housing. A battery power source 23 is also mounted in the blower housing and is electrically connected to the first and second heating elements to energize the heating elements. Preferably, an alternating current to direct current converter 24 is provided either in or out of the blower housing. A charging circuit 25 is provided in the blower housing and are electrically connected to the battery power source for recharging the battery power source.

An elongate flexible electric power cord 27 has a first plug 28 which is inserted into the socket of the blower to electrically connect the power cord to the receptacle of the blower housing and thereby the battery power source. The power cord also has a second plug 29 designed for insertion into an electrical receptacle via the alternating current to direct current converter to electrically connect the power cord to an external electrical power supply.

A motorized fan 30 is mounted in the housing to permit rotation of the fan in the housing. The fan is electrically connected to the battery power source. In use, the fan rotates when energized to blow air from the blower housing into the hose such that heated air from the blower housing through the hose into the space between the inner and outer layers of the cap and out through the apertures of the inner and outer layers of the cap to dry the hair of the user. Preferably, the second face of the blower housing has a plurality of vent holes 31 therethrough to permit drawing of passage of air into the blower housing. The first and second faces of the blower housing preferably facing one another and lie in substantially parallel planes to one another.

A switch 32 is electrically connected to battery power source to selectively activate and deactivate the heater and fan. The switch has an actuator 33 mounted to a third face of the blower housing. A temperature controller 34 is electrically connected to the first and second heating elements to control the amount of heat provided by the heating elements. The temperature controller has an actuator 35 is mounted to a fourth face of the blower housing. Preferably, the switch has at least three settings to control the amount of heat provided by each of the heating elements.

An elongate flexible belt 36 is coupled to a fifth face of the blower housing. The belt has a pair of opposite ends and first and second faces. Preferably, the belt has an adjustment buckle 37 to permit adjustment of the length of the belt between the ends of the belt. In use, the belt is designed for wrapping around a waist of a user such that the first face of the belt faces the waist of the user. The ends of the belt are coupled together preferably a buckle 38 (ideally, a quick-release style buckle) to permit easy detachment of the ends of the belt. Preferably, the first face of the belt has a resiliently compressible padding 39 provided thereon. In use, the padding of the first face of the belt is designed for providing additional comfort to the user when the belt is wrapped around the waist of the user.

Preferably, the fifth face of the blower housing has an opposing pair of generally L-shaped resiliently deflectable arms 40,41. Each of the arms has proximal and distal portions 42,44,43,45. The proximal portions 42,44 of the arms are coupled to the fifth face of the blower housing so that the distal portions 43,45 of the arms are spaced apart from the fifth face of the blower housing. The distal portions of the arms are preferably extended generally perpendicular to the proximal portion of the respective arm. As illustrated in FIG. 3, the belt is extended between the fifth face of the blower housing and the distal portions of the arms to permit sliding of the belt therebetween. The distal portion of the one of the arms overlaps the distal portion of the other of the arms to hold the belt between the arms and the blower housing and to permit deflection of the arms to let the belt pass through the arms when desired.

In an ideal illustrative embodiment, the hose has a length defined between the ends of the hose of about 24 inches and the hairdryer has an overall weight no more than about 2 pounds.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
