Auxiliary unit for face mask to avoid ears being used for anchoring earloops

Abstract

An auxiliary unit for a face mask with earloops comprises a rectangular or oval main body, the main body includes first and opposite second end. At least one first hanger and more than one second hangers are arranged on the main body, the first hanger being close to the first end while the second hangers are closer to the second end. The wearer hangs one of loops of the mask on the first hanger and selects one second hanger for securing the other loop, depending on his head circumstances, therefore, the auxiliary unit releases ears from pressures of anchoring the face mask loops and improves experiences of wearing the face mask.

What is claimed is:

 a main body with a rectangle or an oval structure, the main body comprising a first end and a second end opposite to the first end, the first and the second ends being extendable in an extension direction thereof; and   at least one first hanger and a plurality of second hangers arranged on the main body;   wherein the at least one first hanger is arranged close to the first end, the plurality of second hangers are arranged close to the second end and arranged in the extension direction of the main body; the at least one first hanger and the plurality of second hangers are configured for securing and anchoring two loops of an earloop face mask;   wherein each of the first hanger is formed by a first slot and two second slots connected end to end, wherein one end of each of the second slots is connected to one end of the first slot and the other end of each of the second slots extends in a direction away from the second hangers;   wherein each of the plurality of second hangers is formed by a third slot and two fourth slots connected end to end, wherein one end of each of the fourth slots is connected to one end of the third slot and the other end of each of the fourth slots extends in a direction away from the first hanger.   
     
     
         2 . The auxiliary unit of  claim 1 , wherein a number of the first hangers is equal to a number of the second hangers, the first hangers are arranged in the extension direction of the main body and symmetrically relative to the second hangers. 
     
     
         3 . The auxiliary unit of  claim 2 , wherein a longitudinal direction of each first slot is perpendicular to the extension direction of the main body, and a length of the first slot closer to an outer edge of the main body is longer than a length of the first slot further away from the outer edge of the main body;
 a longitudinal direction of each third slot is perpendicular to the extension direction of the main body, and a length of the third slot closer to an outer edge of the main body is longer than a length of the third slot further away from the outer edge of the main body.   
     
     
         4 . The auxiliary unit of  claim 2 , wherein each of the second slots and each of the fourth slots is provided with a retaining hole at a free end, a diameter of the retaining hole is larger than a width of respective ones of the second slots and the fourth slots. 
     
     
         5 . The auxiliary unit of  claim 2 , wherein each of the second slots and each of the fourth slots include a bending portion, the bending portion is configured to bend the second and the fourth slots in a direction perpendicular to the extension direction of the main body. 
     
     
         6 . The auxiliary unit of  claim 1 , wherein the auxiliary unit comprises identifiers for each of the first hangers and each of the second hangers. 
     
     
         7 . The auxiliary unit of  claim 2 , wherein the auxiliary unit comprises a recess configured for each of the first and each of the third slots, the recess is arranged to form a broaden section for each of the first and each of the third slots. 
     
     
         8 . The auxiliary unit of  claim 2 , wherein each of the second and each of the fourth slots is arranged with a pair of teeth engaged with each other, each pair of teeth comprises a first tooth and a second tooth located on opposite side walls of each of the second and each of the fourth slots. 
     
     
         9 . The auxiliary unit of  claim 1 , wherein the main body comprises a convex part and a flat part, the convex part is located between the first end and the second end, the convex part is adjacent to an outer edge of the main body. 
     
     
         10 . The auxiliary unit of  claim 9 , further comprising four extension parts arranged at four corners of the main body respectively, wherein each of the extension parts is a sector of a circle being positioned with an arc side of the sector close to the wearer's ear, and the arc side of each extension part is fixed to the main body at one end and extends away from the main body at the other end, wherein the first hangers and the second hangers are arranged on the four extension parts, each of the first slots and the third slots are interrupted by the arc sides of the extension parts on the same end of the main body.
