Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-5, the reusable respirator of the present invention includes a respirator 1; the mask 1 is a shell, the mask 1 can cover the mouth and the nose at the same time, a silica gel pad 2 is arranged at the edge of the periphery of the mask 1, and the silica gel pad 2 can enable the mask 1 to be attached to the face of a human body more tightly and comfortably; a through hole (not shown) is formed in the bottom of the breathing mask 1, an air inlet pipeline 4 is arranged on the through hole, and the air inlet pipeline 4 is fixed on the breathing mask 1; a filter 5 is arranged in the air inlet pipeline 4, the filter 5 is an HEPA filter with the filtering efficiency of 99.997 percent, can be replaced for use and can filter particles with the particle size of 0.1-0.3 mu m; the filter is as close to the mouth as possible; an exhaust pipeline 3 is arranged on one side of the middle part of the breathing mask 1; the exhaust duct 3 is as close to the nose as possible; the exhaust pipeline 3 is communicated with the inside and the outside of the breathing mask 1; the breathing mask is characterized in that a support 9 is arranged in the exhaust pipeline 3, the support 9 is positioned at an exhaust port of the exhaust pipeline 3, the support 9 is I-shaped, a lock catch 7 is arranged outside the central part of the support 9, the lock catch 7 is T-shaped, a rubber sheet 6 is arranged between the lock catch 7 and the support 9, a fixing hole is formed in the central part of the rubber sheet 6, the lock catch 7 is inserted into the fixing hole to fix the rubber sheet 6, meanwhile, the rubber sheet 6 is attached to the exhaust port of the exhaust pipeline 3, when the breathing mask exhales, the air pressure in the breathing mask 1 is increased, the rubber sheet 6 can be pushed open, and the air in the breathing mask 1 is exhausted; the thickness of the rubber sheet 6 is 0.1-0.3mm, so that the rubber sheet 6 can be freely deformed, and simultaneously can be attached to the exhaust port of the exhaust pipeline 3 in a free state and seal the exhaust port to form a one-way valve which can only exhaust outwards; hanging lugs 8 are symmetrically arranged on two sides of the respiratory mask 1, elastic ropes can be tied on the hanging lugs 8, and the elastic ropes are used for wearing; the material of respiratory mask 1 is transparent ABS to can see the condition in the respiratory mask 1 clearly when wearing, especially when passing through face identification system, need not to take off respiratory mask 1, can discern.

When the reusable mask is used, a user wears the reusable mask on the head or ears through the elastic ropes tied on the hangers 8, the respirator 1 can cover the mouth and the nose at the same time, when the user inhales air, the rubber sheet 6 is tightly attached to the air outlet of the exhaust pipeline 3 under the action of atmospheric pressure, and external air can only enter the respirator 1 from the air inlet pipeline 4 after being filtered by the filter 5; when a user exhales, the rubber sheet 6 is squeezed to be opened because the air pressure in the breathing mask 1 is greater than the atmospheric pressure outside the breathing mask 1, and the exhaled air can be directly exhausted from the exhaust port of the exhaust pipeline 3; the operation is repeated in a circulating way.

the reusable mask of the utility model is provided with the filter 5 and the one-way valve which can only exhaust air on the respirator 1, and the filter 5 is used for filtering the air intake; the filter 5 can filter particles with the particle size of 0.1-0.3 mu m, the filtering efficiency can reach 99.997%, and the filter 5 can be cleaned or replaced and reused, and has better protection effect.
