Abstract
Various illustrative systems, devices, and methods for face masks are provided. In general, a face mask is configured to provide cooling therapy to a user wearing the face mask. In an exemplary implementation, the face mask includes a thermoelectric cooling device, such as a Peltier device, a thermoelectric cooler (TEC), or other thermoelectric cooling device. The face mask includes a fan configured to blow air configured to dissipate the heat created by the thermoelectric cooling device. The face mask includes a noise attenuation system configured to attenuate the generated noise that is radiated into the environment, and thus, heard by the user due to use of the fan.
Claims19
An apparatus with noise attenuation, comprising:
- a face mask configured to be worn on a face of a user, the face mask comprising:
- a first air inlet through which air external to the face mask is configured to enter a first flow path,
- an air outlet through which the air is configured to exit the first flow path to exit the face mask,
- a first thermoelectric cooling device configured to generate cooling and to generate heat,
- a first fan configured to cause air to enter the face mask through the first air inlet and to flow along the first flow path from the first air inlet to the first fan and from the first fan along the first flow path to the air outlet, and
- at least one of:
- a first flared acoustic waveguide at the first air inlet,
- a first acoustic chamber along the first flow path and located between the first air inlet and the first fan, and
- a first tortuous path along the first flow path and located between the first fan and the air outlet;
- wherein the cooling is configured to be applied to the face of the user with user wearing the face mask;
- and
- the air flowing along the first flow path is configured to dissipate the heat.
An apparatus with noise attenuation, comprising:
- a face mask configured to be worn on a face of a user, the face mask comprising:
- a first thermoelectric cooling device configured to generate cooling and to generate heat, the cooling generated by the first thermoelectric cooling device being configured to be applied to the face of the user with the user wearing the face mask,
- a first fan configured to cause a first air flow configured to dissipate the heat generated by the first thermoelectric cooling device,
- a first noise attenuation system configured to attenuate noise caused by the first fan, the first noise attenuation system including at least one of a first flared acoustic waveguide, a first acoustic chamber, and a first tortuous path;
- a second thermoelectric cooling device configured to generate cooling and to generate heat, the cooling generated by the second thermoelectric cooling device being configured to be applied to the face of the user with the user wearing the face mask,
- a second fan configured to cause a second air flow configured to dissipate the heat generated by the second thermoelectric cooling device, and
- a second noise attenuation system configured to attenuate noise caused by the second fan, the second noise attenuation system including at least one of a second flared acoustic waveguide, a second acoustic chamber, and a second tortuous path.
