초록 ▼

A breathing mask is provided which comprises an exhaling valve disposed in an opening of the breathing mask wall. The exhaling valve includes a thin diaphragm which is adapted to be moved by the breathing pressure during inhaling and exhaling either towards or away from a sealing seat. To provide a less expensive breathing mask whose exhaling valve safely closes in particular in dust-particle-containing air and which nevertheless involves low opening and closing pressures, the diaphragm is provided with an arch. Air is allowed to escape over only a part of the circumference of the diaphragm, while the remaining part of the diaphragm circumference is so connected to a base member that the arching direction of the arch is at least partly reversible by the breathing pressure.

대표청구항 ▼

A breathing mask comprising a filter wall being permeable to air in both inhaling and exhaling directions, said filter wall having an inner face side and an outer side and containing an opening therein, and an exhalation valve being sealingly disposed within said opening, said exhalation valve having an inlet which opens toward said face inside and an outlet which is disposed at the outer side of said wall, said exhalation valve further comprising a base member extending through said opening and having a reduced diameter portion clampingly engaged with said opening for buttoning said valve into said wall, and a thin flexible diaphragm integrally formed with said base member, and adapted to be moved by pressure applied thereon during inhaling and exhaling, said diaphragm covering said opening at said outer side by extending essentially across said exhaling and inhaling direction, in said diaphragm being connected to said base member over a first part of a circumferential line of said diaphragm while a second part of said circumferential line remains unconnected to said base member thus forming said outlet of said exhalation valve, said diaphragm having a portion of a concave curvature of greater than zero degrees extending into said opening when said diaphragm is in a rest position with no pressure of exhaling applied thereto, while, under pressure of exhaling, said portion of said diaphragm at least partially has a convex curvature, said diaphragm having a sealing surface facing a corresponding sealing surface arranged at said base member adjacent said opening, said sealing surfaces being adapted to be pressed into sealing contact by pressure of inhaling.
