Novel respirator

Abstract

The invention discloses a novel respirator comprising a mask and a respiration filter device. The mask comprises a base, an outer cover and an inner cover, the edge of the outer cover is clamped on an outer upper platform of the base, the inner cover is clamped on an inner upper platform of the base, and the respiration filter device is clamped between the outer cover and the inner cover. The novel respirator further comprises an inflatable or deflatable hollow air bag which is detachably connected with the base. The shape of the air bag can be adjusted according to facial contours and shapes of nose bridges of different wearers, and adaptation of the respirator and comfort of the wearers are enhanced remarkably; meanwhile, the outer side face of an air bag body is provided with a soft sweat-absorbent pad which can absorb sweat generated by the wearer when using the novel respirator in an environment at high temperature; in addition, the latticed inner cover is directly connected with the base to form a respiratory air cushioning cavity, so that the structure of the respirator is simplified greatly; a one-way air outlet valve component is arranged in the middle of the inner cover, so that exhaled air of human bodies can be discharged out of the respirator to allow the wearers to breathe more smoothly.

Description

[0001] technical field [0002] The invention relates to the field of respirators, in particular to a novel respirator. [0003] Background technique [0004] The respirator was developed for the use of chemical warfare agents in World War I and has been widely used in various fields. At present, general respirators have the following technical features: the respirator inner cover is adapted to form a seal against the face, thereby providing a cavity for the respirator, the inside of the outer cover is provided with a filter, and the outside air passes through the outer cover filter After entering the cavity of the inner cover through a connection port and inhaling the human body, the filter removes harmful substances from the inhaled air, and the respirator outer cover can prevent external, potentially harmful air from entering the cavity and thus entering the wearer in the lungs. When exhaling, the positive pressure generated by the wearer’s exhalation is generally disc...

AI Technical Summary

Problems solved by technology

[0005] Yet existing respirator has the following deficiencies and is: 1, existing respirator all adopts fixed setting at the contact position with human body face, and respirator can not be adjusted according to the shape of facial outline or bridge of the nose, thereby causes respirator Can not be suitable for the user of all different facial features; 2: the soft plastic material that existing respirator adopts in the contact position with human body face, does not absorb water, and sweat has nowhere to penetrate under the higher temperature environment, and moisture gathers in respirator The parts in contact with the face may feel uncomfortable and easily damage the skin of the contact parts after long-term use

3. Commonly used simple respirators (that is, ordinary masks) have poor sealing and cannot effectively block harmful substances from entering the human body. There is no separate exhalation component, and it is difficult to expel the exhaled gas from the mask as soon as possible.

4. All existing respirators have poor comfort and single practical function
