DETAILED DESCRIPTION

[0025] The innovation presented here is now described with reference to the drawings, where like reference numerals are used to refer to like elements throughout the specification. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these individual specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof.

[0026] As noted above, there exists a long felt need in the art for an improved protective, surgical or medical mask that reduces of prevents the discomfort typically associated with a user wearing a tight fitting, ear loop-based mask. There also exists in the art a long felt need for an improved face mask that has a securing strap that is more effective and easier to use than current protective or medical mask designs, in addition to being more comfortable than both tied and loop medical mask designs. Additionally, there exists a long felt need in the art for a face mask that reduces the breathability issues faced by users of conventional prior art masks due to sealing engagement between the mask and wearer's skin, and the lack of proper air circulation and ventilation. Moreover, there exists a long felt need in the art for a face mask that provides for active air circulation and ventilation to aid the breathing of the user, and for a relatively compact and inconspicuous powering mechanism to provide power to the circulation/ventilation assembly. Finally, there is a long felt need in the art for an affordable, easy to use and comfortable face mask that provides superior protection against contamination due to air-borne bacteria, microbes, pathogens, particulates, germs, and the like.

[0027] The subject matter disclosed and claimed herein, in one embodiment thereof, comprises an improved protective face mask. More specifically, the electronic air flow protective face mask is comprised of a mask body with a front hooked surface having ear loops and a loop-backed reusable and washable strap attached to the mask body. The mask body covers the nose and mouth of a wearer and provides enhanced and active air circulation and ventilation, thereby reducing the risk of suffocation and breathing difficulty encountered with typical face masks. More specifically, the air flow mask of the present invention includes a fan powered by a battery, which enables the intake of fresh air and the exhaust of released or exhaled breath through a filter body contained within the mask. The mask body of the electronic face mask may be manufactured using a plastic, a cloth, a non-woven material, a PTE material, or any other mask material that satisfies the needs and/or preferences of the user or manufacturer.

[0028] Referring initially to the drawings, FIG. 1 illustrates a front perspective view of one possible embodiment of the electronic airflow mask 100 of the present invention being utilized by a user 150 in accordance with the disclosed architecture. The electronic airflow mask 100 is preferably comprised of a mask body portion 110, an adjustable or elastic strap assembly 130, a formable nose bridge portion 112, a fan 114, a battery 116 and a USB port 118, each of which are described more fully below.

[0029] The mask body 110 is a generally cup shaped structure that fits comfortably over the nose 154 and mouth 156 of the user 150. Face mask bodies 110 of the present invention intended for use with an adult are preferably about 7 to about 13 inches in width (as measured between sides), and about 3 to about 5 inches in height (as measured between the top and bottom), and expandable. The mask body 110 further comprises a vertical fold line 111 that substantially divides the mask body 110 in half. When the mask 100 is worn by the wearer 150, this fold line or crease line 111, is more or less aligned with an imaginary vertical line passing through the center of the forehead, the nose 154, and the center of the mouth 156 of the user. The portion of the mask body 110 on the right side of the fold line 111 is referred to as the right mask body 1101, and the portion on the left side of the fold line 111 is referred to as the left mask body 1102. As further described below, the fan 114, battery 116, USB charging port 118 any other components may be disposed on either body portion of the mask 100, such as the right mask body 1101 or the left mask body 1102. Alternatively, the mask 100 may be offered with a fan 114 positioned on both sides of the mask body 110 to increase the amount of air circulation.

[0030] The nose bridge portion 112 of the mask body 110 is positioned over a top edge 1105 which runs across one side of the face to the other side over the nose 154. The nose bridge or nose-clip 112 includes an elongated deformable member that is positioned along the upper edge 1105 of the mask, and holds it in place once formed over the bridge of the wearer's nose 154. The wearer 150 may adjust the nose-bridge portion 112 depending on the size and contour of the wearer's nose to increase comfort and fit.

[0031] The mask body 110 is preferably comprised of a filter material, such as a non-woven fabric, a cloth, a PTE material, or any other suitable mask material which filters out pathogens, microbes, pollutants and other harmful germs from the air breathed in through the mask body 110, thereby providing pure or filtered air to the user's 150 respiratory system and preventing any type of cross contamination and the spread of diseases. More specifically, the material of the mask body 110 is preferably a particulate, bacteria filter, and is made from a non-woven, melt blown filter material that is comprised of 100% polypropylene or other suitable material. The mask body 110 acts as a fine particulate filter, thereby protecting the user 150 against at least 95% of any airborne dust, particulates, pathogens, or bacteria of 0.3+ microns sized particles. In differing embodiments of the electronic airflow mask 100, the material of the mask body 110 may include a coarse particulate filter that precedes the fine particulate filter to further protect the user 150 from larger/more coarse particulates. In this embodiment, the user may have first and second filter layers built into the mask 100. Further, the material of the mask body 110 may be made of cloth or PTE material which is sufficient capable of filtering harmful particles in the air and prevents the user from encountering any contamination and helps to avoid the spread of diseases.

[0032] A foam structure may also be located on a perimeter of the mask body 110 to increase the comfort of the wearer 150, and to act as a further barrier to airborne pathogens. Accordingly, the foam-based lining on the perimeter of the mask body 110 is preferably non-permeable to pathogens/bacteria. Moreover, the foam-based lining on the perimeter of the mask body 110 widens the surface area of the mask body 110 perimeter so that the pressure that the face mask 100 exerts against the skin on the face of the wearer 150 when worn is distributed across a wider surface area, thereby reducing the overall pressure of the mask body 110 on the user's skin which can lead to rashes, skin irritation or other skin related issues. In a further preferred embodiment of the present invention, the perimeter may also have a skin-safe adhesive backing that aids the mask body 110 in forming a better seal against the face of the user 150.

[0033] The mask body 110 further comprises an inner surface and an outer surface, in which the inner surface is facing the wearer 150 and the outer surface is facing away from the wearer 150. The outer surface of the mask body 110 can display without limitation, any number of patterns, colors, logos, text, slogans, trademarks, etc. desired by the wearer 150, thereby allowing the wearer 150 to easily customize the electronic airflow face mask 100 of the present invention for their own personal preference.

[0034] The strap assembly 130 forms a right ear loop 120 and a left ear loop 122, secured, respectively, on a right ear 160 and a left ear 162 of the user 150. The strap assembly 130 further includes a first strap and a second strap secured at the back of head 158 of the user 150. The strap assembly 130 can be secured and adjustably tightened by the user 150 using, for example, a ladder lock buckle or similar fastening mechanism. Other strap adjustment mechanisms may also be used. The strap assembly 130 may be manufactured using an elastic material, VELCRO strap or other material, as per the preferences of the user or specifications of the manufacturer.

[0035] FIG. 2 illustrates a left perspective view of one possible embodiment of the electronic airflow mask 100 of the present invention being utilized by a user 150 in accordance with the disclosed architecture. More specifically, the strap assembly 130 forms a left ear loop 122 which is secured on a left ear 162 of the user 150. A first strap 1301 and a second strap 1302 are also secured over the back of the head 158 of the user 150, which can be adjusted and secured to the head 158 using, for example, a ladder lock buckle or other strap adjusting mechanisms. The first strap 1301 is attached to a top edge 1105 of the mask body 110 in an extended position, and the second strap 1302 is attached to a bottom edge 1106 of the mask body 110 and extends around the backside of the head 158, thereby helping to secure the mask body 110 to the face of the wearer 150.

[0036] As best illustrated in FIG. 2, a fan 114 is disposed on a left side of a fold line 111, and a left portion of nose bridge 112 is disposed on the upper edge 1105 of left mask body 1102 to provide a better fit of the mask body 110 relative to the face of the user 150. When in operation, the fan 114 draws exhaled air out of the interior portion of the mask body 110, and draws fresh air into the interior portion of the mask body 110, thereby providing comfort to the wearer 150, and helps reduce breathability or respiratory issues encountered with traditional tight-fitting face masks. The fan 114 allows the wearer 150 to inhale and exhale with greater ease. More specifically, when the wearer 150 is inhaling while wearing the electronic face mask 100, the fan 114 provides the wearer with access to fresh and filtered air, which enters through the fan valve and through the mask body 110 filter material. Likewise, when the wearer 150 is exhaling while wearing the electronic face mask 100, the fan 114 effectively removes the hot and moist breath of the wearer 150, and expels the air to the outside atmosphere, which also prevents the fogging of eyeglasses if also worn by the wearer 150.

[0037] The fan 114 may be positioned over the outer surface of the mask body 110, or it may be removably or permanently affixed to the mask body 110 by using an adhesive, VELCRO, or any other suitable type fastener. As previously stated, the fan 114 is preferably placed over the filter material of the mask body 110 to filter the air which enters the mask portion from the external environment through the fan 114. The fan 114 may also operate at different speeds or in different directions as per the needs and preferences of the user 150.

[0038] As best shown in FIGS. 1 and 3, the fan 114 is in electrical communication with a power source, such as battery 116, an electrical cord, a coil spring or other suitable power source, which supplies the power necessary to operate the fan 114. The connection between the fan 114 and the power source is preferably accomplished through an internal and relatively lightweight wiring mechanism. The fan 114 may also be connected to a controller (not shown) for manipulating the operation and speed of the fan 114. The controller connects the fan 114, power source, and other components of the mask 100. In a preferred embodiment of the present invention, the mask 100 may further comprise one or more sensors 140 to detect, for example, the humidity and temperature levels on the interior of the mask body 110 which, through the controller, may increase or decrease the speed of the fan 114. The sensor 140 may also be used to detect contamination levels of the mask filters to determine when the mask 100 needs to be discarded. The sensor 140 can also include a chemical sensor to determine permeability rates of the filter and the buildup of particular types of pathogens, pollutants or microbes. The mask 100 and sensor 140 may further include a color indicator to determine the age or number of days the mask 100 has been in use.

[0039] FIG. 3 illustrates a right perspective view of one possible embodiment of the electronic airflow mask 100 of the present invention being utilized by a user 150 in accordance with the disclosed architecture. As shown in FIG. 3, the strap assembly 130 forms a right ear loop 120 which is secured on a right ear 160 of the user 150. A first strap 1301 and a second strap 1302 are secured over the back of the head 158 of the user 150, and can be adjusted and secured to the head 158 using, for example, a ladder lock buckle 300 or other strap adjusting mechanisms. The first strap 1301 is attached to a top edge 1105 of the mask body 100 in an extended position, and the second strap 1302 is attached to a bottom edge 110 of the mask body 110 and extends around the back of the user's head 158. The strap assembly 300 of the present invention provides a comfortable face mask 100 securing mechanism, and prevents the pain or discomfort typically experienced by wearers of prior art masks. Ideally, the first and second straps 1301, 1302 are spaced apart by approximately 2 to 3 inches to ensure a secure attachment of the mask 100 to the wearer 150.

[0040] Referring now to FIG. 3, a right mask body 1101 has a power source 116, a USB charging port 118, a controller 310 and a button 320 disposed on a right side of the fold line 111. The right portion of the nose bridge 112 is disposed on the upper edge 1105 of right mask body 1101 to provide a better fit of the mask body 110 to the face of the user 150. Additionally, the power source 116 is connected to the fan 114, which is disposed on the left mask body 1102 to supply power for the operation of the fan 114.

[0041] The power source 116 is preferably a battery (e.g., single use or rechargeable), but is not limited thereto and other power supply sources can be used to operate the fan 114. More specifically, the power source 116 may contain one or more rechargeable batteries, which can be charged by utilizing the USB charging port 118. A USB cable may be connected to the USB charging port 118 of the mask 100 and to a power supplying source, such as a power bank, electrical outlet or other source. The batteries 116 can be charged at any time, including when the mask 100 is in operation and the fan 114 is turned ON. The mask 100 may be powered using nickel metal hydride (NiMH), nickel cadmium (NiCd) batteries, or any other type of batteries known in the state of the art to power small electronic devices.

[0042] The controller 310 is a central unit for the operation of the electronic airflow mask 100, and manages the operation of fan 114. The controller 310 connects the fan 114, button 320 and the power source 116, and enables the fan 114 to operate in accordance with the instructions of a user 150. The button 320 may be a push button, a switch, a touch button or any other means for activating or deactivating the fan 114. Additionally, the button 320 may be sewn to an outer surface of the mask body 110, or may be affixed thereto using any suitable adhesive including, without limitation, surgical adhesives or sealants marketed under the name DERMABOND or the like.

[0043] The user 150 may push the button 320 once to turn on the fan 114, thereby allowing the fan 114 to expel hot and moist air from the interior of the mask body 110, as well as draw fresh air from the surrounding environment to enter inside the mask body 110 for the use's convenience and to aid the user 150 in breathing. The user 150 may push the button 320 a second time to turn off the fan 114. Turning the fan 114 off when not needed reduces power consumption and increases the life of the batteries 116 between charges.

[0044] Alternatively, the fan 114 may be controlled remotely by a corresponding application for the electronic airflow mask 100, such as a mobile application downloaded to a smartphone or other smart device. To that end, in a further embodiment of the present invention, the electronic airflow mask 100 may further comprise wireless connectivity modules (not shown) such as, but not limited to, Bluetooth, Wi-Fi, NFC, RFID, to wirelessly connect the airflow mask 100 to a smartphone or any other electronic device running an application to operate the mask 100 and control the speed and/or direction of the fan 114.

[0045] More specifically, as the user 150 presses the button 320 once, or wirelessly turns ON the fan 114 of the mask 100 by utilizing a corresponding smartphone application, a signal is sent to the controller 310, which further coordinates with the power source 116 to supply power to the fan 114 and start the airflow through the fan 114. When in operational mode, the fan 114 expels exhaled air out of the interior portion of the mask body 110, and/or draws fresh air into the interior portion of the mask body 110, thereby allowing the wearer 150 to inhale and exhale through the mask body 110 with greater ease. More specifically, when inhaling while wearing the electronic face mask 100, the fan 114 provides the wearer 150 with access to fresh air, which enters through the fan valve and through the mask body 110 including the filter material. When exhaling while wearing the electronic face mask 100, the fan 114 effectively removes the hot and moist expelled breath of the wearer 150, and further helps to prevent the fogging of eyeglasses that may be worn by the wearer 150.

[0046] Further, the button 320 may be operated to change the speed of the airflow of the fan 114. As an example, a long press of button 320 may trigger a medium speed of fan 114, or the button 320 may be long pressed consecutively to trigger, for example, a higher fan speed. Further, the smartphone application corresponding to the mask 100 may have a feature for changing the speed or direction of the fan 114, as per the preferences of the user.

[0047] Additionally, and as best shown in FIGS. 2 and 3, the adjustable strap assembly 130 is comprised of a first strap 1301, a second strap 1302, and a ladder lock buckle 300. The first strap 1301 is preferably sewn at an end of the top edge 1105 (i.e., the corner), and the second strap 1302 is sewn at an end of the bottom edge 1106 (i.e., the corner). The straps 1301 and 1302 are sewn after they have been looped around the ladder lock buckle 300, and may be secured in place by a series of stiches or other fastening means so that they are affixed to the buckle 300 permanently.

[0048] A user 150 may adjust the tightness of all strap assemblies 1301 and 1302 via pulling the straps 1301 or 1302 through or out of the ladder lock buckle 300. Unlike existing tied masks, the strap assembly 130 of the present invention provides a user 150 with a means of securing the electronic airflow face mask 100 to the user's face without requiring a user 150 to tie the straps, which could be an issue for elderly users and/or users with disabilities. In addition, the strap assembly 130 of the present invention has a much lower probability of coming unfastened while in use than a tied mask. Further, the straps 1301, 1302 may be made up of any elastic material, VELCRO strap or any other material which is flexible and stretchable.

[0049] The smartphone application may be a software application which is installable on any compatible electronic device. The electronic device may be a smartphone, a laptop, a tablet, or any other electronic device. The software application may be used to enable different features of the electronic airflow mask 100, and to operate the mask 100 remotely.
