US3854489A — Hair styling appliance

Claim 1

Independent Claim 128 words

A hair styling appliance for simultaneously applying a liquid spray and hot air stream to hair as it is combed or brushed, comprising, in combination: a housing; a nozzle for injecting a mist into said hot air stream; a liquid reservoir; means comprising a manually actuable liquid pump communicating with said reservoir for drawing liquid therefrom; pump actuator means for actuating said pump; means comprising a liquid passageway extending between said pump and said nozzle for supplying liquid under pressure to said nozzle; and means comprising a pressure relief valve disposed within said liquid passageway adjacent the discharge end thereof for inhibiting the flow of said liquid through said passageway when said pump is not being actuated to prevent the unintentional discharge of liquid into said air stream.

Claim 2

Dependent Claim 128 words

A hair styling appliance for simultaneously applying a liquid spray and hot air stream to hair as it is combed or brushed, comprising, in combination: a housing; a nozzle for injecting a mist into said hot air stream; a liquid reservoir; means comprising a manually actuable liquid pump communicating with said reservoir for drawing liquid therefrom; pump actuator means for actuating said pump; means comprising a liquid passageway extending between said pump and said nozzle for supplying liquid under pressure to said nozzle; and means comprising a pressure relief valve disposed within said liquid passageway adjacent the discharge end thereof for inhibiting the flow of said liquid through said passageway when said pump is not being actuated to prevent the unintentional discharge of liquid into said air stream.

Claim 3

Dependent Claim 58 words

A hair styling appliance as defined in claim 1 wherein said flow inhibiting means comprise a pressure relief valve serially disposed in said passageway which opens only in response to a predetermined minimum pressure in said passageway, and wherein said pump when actuated produces a pressure in said passageway equal to or greater than said predetermined minimum pressure.

Claim 4

Dependent Claim 49 words

A hair styling appliance as defined in claim 2 wherein said pressure relief valve comprises a plurality of resilient valve sections hinged about one end of a hollow cylindrical body member coaxially disposed within said passageway, which coact in the absence of said predetermined pressure to block said passageway.

Claim 5

Dependent Claim 173 words

A hair styling appliance for applying a liquid hair spray and hot air stream to hair as it is combed or brushed, comprising, in combination: a housing; a fan and heater assembly for generating a stream of heated air; a spray nozzle for injecting a mist into said hot air stream; a liquid reservoir, including a removable cap; means comprising a manually actuable pump mounted on said cap for drawing fluid from said reservoir, said pump having a discharge port at one end; means comprising a chamber within said housing for slidably receiving said reservoir, said chamber including an access opening dimensioned to enable said liquid reservoir to be removed from said housing; means including a liquid receiving port withIn said chamber for establishing a liquid path between said discharge port and said spray nozzle when said reservoir is seated in said chamber; and actuator means operable by a user for actuating said pump while said reservoir is in said seated position to inject liquid from said reservoir into said hot air stream.

Claim 6

Dependent Claim 173 words

A hair styling appliance for applying a liquid hair spray and hot air stream to hair as it is combed or brushed, comprising, in combination: a housing; a fan and heater assembly for generating a stream of heated air; a spray nozzle for injecting a mist into said hot air stream; a liquid reservoir, including a removable cap; means comprising a manually actuable pump mounted on said cap for drawing fluid from said reservoir, said pump having a discharge port at one end; means comprising a chamber within said housing for slidably receiving said reservoir, said chamber including an access opening dimensioned to enable said liquid reservoir to be removed from said housing; means including a liquid receiving port withIn said chamber for establishing a liquid path between said discharge port and said spray nozzle when said reservoir is seated in said chamber; and actuator means operable by a user for actuating said pump while said reservoir is in said seated position to inject liquid from said reservoir into said hot air stream.

Claim 7

Dependent Claim 51 words

A hair styling appliance as defined in claim 4 wherein said pump discharge port comprises an elongated nozzle, said liquid receiving port comprises a cup-like recess for receiving said nozzle in sealing engagement, and said actuator means include a linkage for forcing said recess against said nozzle to actuate said pump.

Claim 8

Dependent Claim 32 words

A hair styling appliance as defined in claim 5 which further includes a closure member hinged to said housing for closing said access opening and confining said reservoir in said seated position.
