Abstract
Embodiments relate generally to respirator face masks, and specifically to powered face masks which may be custom-controllable to better provide for the specific air needs of the individual user wearing the mask. For example, the face mask embodiments typically include a filter and a motorized fan, both generally located on the face mask itself, along with a processor. The processor then may use inputs, for example specific to the user and/or the environment, to control the fan speed. Thus, the fan speed of the face mask may be custom controlled to provide the appropriate amount of filtered air as the specific user needs it.
Claims18
A filtration mask, comprising:
- a filter;
- a motorized fan configured to direct air through the filter into the filtration mask;
- a housing configured to support the filter and the motorized fan and comprising an inner shell;
- two or more sensors, wherein a first sensor of the two or more sensors is configured to generate data indicative of particulates which have passed through the filter, wherein a hall sensor of the two or more sensors is mounted on an outer surface of the inner shell in proximity to an exhalation valve of the filtration mask and configured to generate customization data indicative of a breathing frequency of a user;
- and
- a processor communicably coupled with the hall sensor and the motorized fan, the processor configured to:
- receive the customization data,
- modify a speed of the motorized fan based upon the customization data so as to modify a speed of the air directed through the filter and into the filtration mask such that an amount of air provided to the user is more than a target amount of air determined by the processor based on the customization data,
- receive each of pollution data from internet and the data indicative of particulates which have passed through the filter from the two or more sensors,
- compare the data indicative of particulates which have passed through the filter with the pollution data;
- and
- transmit an output signal to a device based on a result of the comparison.
A method of controlling a filtration mask, comprising:
- providing the filtration mask comprising:
- a filter;
- a motorized fan configured to direct air through the filter of the filtration mask;
- a housing configured to support the filter and the motorized fan and comprising an inner shell;
- and
- two or more sensors wherein a first sensor of the two or more sensors is configured to generate data indicative of particulates which have passed through the filter, wherein a hall sensor of the two or more sensors is mounted on an outer surface of the inner shell in proximity to an exhalation valve of the filtration mask and configured to generate customization data indicative of a breathing frequency of a user;
- wherein the method comprises:
- receiving, via a processor, pollution data from internet and the customization data;
- modifying, by the processor, a speed of the motorized fan based upon the customization data so as to modify a speed of the air directed through the filter and into the filtration mask such that an amount of air provided to the user is more than a target amount of air determined by the processor based on the customization data;
- generating, by the first sensor, the data indicative of particulates which have passed through the filter,
- comparing, by the processor, the data indicative of particulates which have passed through the filter with the pollution data, and
- transmitting, by the processor, an output signal to a device based on a result of the comparison.
