Custom-controllable powered respirator face mask
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.
1. A filtration mask, comprising:
a filter;
a motorized fan configured to direct air through the filter into the filtration mask, wherein the motorized fan is variable speed;
a housing configured to support the filter and the motorized fan, the housing comprising an outer shell and an inner shell, wherein the outer shell and the inner shell each define one or more apertures to allow air flow from an external environment of the filtration mask through the filtration mask to a user of the filtration mask;
an exhalation valve mounted on an outer surface of the inner shell and operable to direct exhaled air outward from the inner shell while preventing the entrance of air through the exhalation valve;
a hall sensor mounted on the outer surface of the inner shell and in proximity to the exhalation valve, the hall sensor configured to generate customization data indicative of a breathing frequency of the user;
one or more sensors wherein a first sensor of the one or more sensors is configured to generate data indicative of particulates which have passed through the filter; 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 data indicative of particulates which have passed through the filter from the one 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.
2. The filtration mask according to claim 1
a second sensor of the one or more sensors is configured to generate second customization data;
wherein the processor is further configured to:
receive the second customization data; and
modify a speed of the motorized fan based on the second customization data.
3. The filtration mask according to claim 2 , wherein the processor is further configured to determine a walking speed or heart rate of the user based on the breathing frequency of the user.
4. The filtration mask according to claim 2 , wherein the housing further comprises a middle shell located between the filter and the motorized fan, and wherein the middle shell comprises one or more apertures over which the filter is mounted.
5. The filtration mask of claim 4 , wherein the outer shell substantially covers a portion of the inner shell upon which the middle shell is positioned.
6. The filtration mask according to claim 2 , wherein the second customization data comprises a humidity of an external environment of the filtration mask.
7. The filtration mask according to claim 2 , wherein the second customization data comprises a temperature of an external environment of the filtration mask.
8. The filtration mask according to claim 2 , wherein the second customization data comprises a heart rate of the user of the filtration mask.
9. The filtration mask according to claim 2 , wherein the second customization data comprises a pressure of an external environment of the filtration mask.
10. The filtration mask according to claim 2 , wherein the processor is further configured to receive third customization data from the device, wherein the third customization data comprises a physical location of the user of the filtration mask.
11. The filtration mask according to claim 2 , wherein the second customization data comprises a walking speed of the user of the filtration mask.
12. The filtration mask according to claim 2 , wherein the processor is further configured to receive third customization data from the device based on a user input obtained at the device, wherein the third customization data comprises at least one of a height, weight, or age of the user of the filtration mask.
13. The filtration mask according to claim 2 , further comprising a battery configured to power at least one of the processor or the motorized fan.
14. The filtration mask according to claim 13 , wherein the processor is further configured to modify the speed of the motorized fan at least in part based on battery life of the battery.
15. The filtration mask according to claim 1 , wherein the first sensor is a particulate matter (PM) 2.5 sensor.
16. A method comprising: controlling of a filtration mask, the filtration mask comprising: a motorized fan configured to direct air through a filter of the filtration mask,
a housing configured to support the filter and the motorized fan, the housing comprising an outer shell and an inner shell, wherein the outer shell and the inner shell each define one or more apertures to allow air flow from an external environment of the filtration mask through the filtration mask to a user of the filtration mask;
an exhalation valve mounted on an outer surface of the inner shell and operable to direct exhaled air outward from the inner shell while preventing the entrance of air through the exhalation valve; and
a hall sensor mounted on the outer surface of the inner shell and in proximity to the exhalation valve, the hall sensor configured to generate customization data indicative of a breathing frequency of a user of the filtration mask, wherein controlling the filtration mask 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 a sensor, 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.
