Cold temperature hair brush
A hair brush includes a housing and a cooling device in the housing. A comb is in thermally conductive contact with the cooling device and adapted to be cooled when thermal energy in the form of heat is transferred by the cooling device in a direction away from the comb. The comb has a hair contacting surface. The hair contacting surface comprises one or more teeth adapted to directly engage a user's hair.
1. A hair brush comprising:
a housing having a brush portion and a handle portion, the housing having a first end on the brush portion and a second end that is opposite the first end on the handle portion, the first end of the housing on the brush portion being closed;
a cooling device in the housing, the cooling device having a hot side and a cool side, and the hot side of the cooling device contacting a heat sink that is in the housing;
a comb having one or more teeth that extend from the brush portion of the housing, the comb having the one or more teeth being metallic or material that is thermally conductive, the comb is in direct physical contact with the cool side of the cooling device and is cooled when thermal energy in the form of heat is transferred by the cooling device in a direction away from the comb so that the cooling device cools the comb by thermal conduction, and the heat sink that is in the housing draws heat away from the comb;
one or more fan assemblies to remove the heat in the brush portion of the housing, the heat sink being between the cooling device and the one or more fan assemblies;
wherein the comb has a hair contacting surface;
wherein the hair contacting surface comprises the one or more teeth adapted to directly engage a user's hair,
wherein the hair brush cools the user's hair only through thermal conduction by contact with the one or more teeth of the comb and/or the one or more teeth of the comb and the housing,
wherein the housing has a first side and a second side that is opposite the first side,
wherein the comb extends from the first side and the second side is free of bristles and teeth,
wherein the housing has vents through the second side,
wherein the first side of the brush portion is only cooled and the heat is released into the ambient air through the vents through the second side so that the one or more fan assemblies assist in moving heat away from the heat sink in an airflow and the vents release the airflow into the ambient air, and
wherein the airflow is only on the hot side of the cooling device so that there is no airflow on the cool side of the cooling device.
2. The hair brush of claim 1 , further comprising an ionizer in the housing.
3. The hair brush of claim 1 , wherein the cooling device is connected to a plug.
4. The hair brush of claim 1 , wherein the cooling device is connected to a battery.
5. The hair brush of claim 4 , wherein the battery is connectable to a power source through a USB outlet.
6. The hair brush of claim 1 , further comprising an opening in the housing, and a portion of the hair contacting surface extends through the opening.
7. The hair brush of claim 6 , further comprising a plurality of bristles that extend from the housing to surround the hair contacting surface.
8. The hair brush of claim 6 , wherein the comb is a first comb and further comprising a second comb, wherein the first comb and the second comb are each selectively connectable to the housing, and wherein the first comb and the second comb are interchangeably connectable to the housing.
9. The hair brush of claim 6 , wherein the housing is metal, and wherein the cooling device cools the housing.
10. The hair brush of claim 6 , wherein the one or more teeth of the comb form a central row of teeth centered between a U-shaped array of bristles, and wherein the teeth have a width dimension greater than a width of each of the bristles.
11. The hair brush of claim 1 , wherein the teeth of the comb each have a half-oval shaped perimeter, and wherein the teeth of the comb each extend from a support that is in direct physical contact with the cool side of the cooling device.
