Embodiment Construction

[0023] Fig. 1 has shown the specific embodiment of compartment mask of the present invention. The periphery of outer cover 3 is peripheral sealing ring 1, so that mouth mask and people's face are fully fitted. The inner side of the outer cover 3 is separated into a nasal cavity 2 and an oral cavity 8 by a cavity plate 4 . The inner side of the compartment plate 4 is provided with a compartment sealing edge 9 , and the compartment plate 4 is provided with an intracavity check valve 5 . The outer cover 3 of the nasal cavity 2 is provided with a one-way valve 6 for discharging the nasal cavity, and the outer cover 3 of the oral cavity 8 is provided with a one-way valve 7 for discharging the oral cavity. Nasal cavity 2 and oral cavity 8 share a larger filtered air inlet 10 .

[0024] When people normally use masks to inhale, when the filtered air inlet 10 enters the fresh air to the nasal cavity 2 and the oral cavity 8, the nasal cavity discharges the one-way valve 6 and the ora...

Abstract

The invention discloses a mask with isolated cavities. The mask comprises a periphery seal ring, a nose cavity, an outer cover, a cavity isolating plate, an in-cavity one-way valve, a nose cavity discharge one-way valve, a mouth cavity discharge one-way valve, a mouth cavity, a cavity isolating seal edge and a filtered air inlet and is characterized in that the inner cavity of the mask is isolated into the nose cavity and the mouth cavity, the in-cavity one-way valve which allows the air of the nose cavity and the mouth cavity to be discharged independently is disposed on the cavity isolating plate, and the problem that a user wearing a traditional mask feels flustered and stuffy due to the fact that the traditional mask is large in waste air space occupation and low in waste air exchange rate, and the heat of the waste air is stuck to the face of the user is solved.

Description

technical field [0001] The invention relates to a mask, in particular to a mask that isolates the inner cavity of the mask into a nasal cavity and an oral cavity, and is provided with a one-way valve in the cavity on the cavity plate, so that the gas in the nasal cavity and the oral cavity can be discharged separately, thereby solving the problem of The exhaust gas occupies a large space, the exhaust gas replacement rate is low, and the heat of the exhaust gas sticks to the face, which causes people to feel flustered and stuffy when wearing the mask. Background technique [0002] Pneumoconiosis is a serious disease in the prevention and control of occupational diseases all over the world. According to reports from authoritative organizations: At present, there are at least 6 million domestic cumulative cases of pneumoconiosis and suspected pneumoconiosis (0+) cases in China. I also believe that this number is not too small, because my "pressure-guiding bedpan" patent was im...
