Embodiment 1

[0012] Such as figure 1 , figure 2 , image 3 As shown, the one-way air delivery open type mask includes a mask body 1, a filter air delivery device 2, an air delivery tube 3 connected to the filter air delivery device 2 and passing through the mask body 1. The air delivery tube 3 is located below the nostril and is provided with a horn The horn-shaped breathing window 4 is in vertical communication with part of the air pipe 3 in the mask body 1 to ensure that the air flow direction of the horn-shaped breathing window is perpendicular to the air flow direction of the air pipe 3 to form an air curtain. The air flow direction of the air pipe 3 in the mask body 1 is perpendicular to the air flow direction of the breathing window 4, the end of the air pipe 3 is an exhaust hole 31, and the exhaust hole 31 is always in an open state. The filter air delivery device 2 uses a micro electric fan 22 to continuously deliver the filtered clean air to the air delivery pipe 3. The route and ...

Embodiment 2

[0014] Such as figure 1 , figure 2 As shown, the air pipe 3 is located in the mask body 1 with an air distribution box 32, the thickness of the air distribution box 32 is greater than the diameter of the air pipe 3, and the horn-shaped breathing window 4 is vertically installed in the air distribution box 32 , And communicate with the distribution box 32.

Embodiment 3

[0016] Such as image 3 As shown, the filter air delivery device 2 includes a housing 21, a fan 22 arranged in the housing 21, two air inlets 23 arranged on both sides of the fan 22 and located on the housing 21, and an air inlet 23 arranged on the air inlet 23. The filter membrane 24, the air outlet 27 provided on the housing 21, the negative ion generator 25 provided between the fan 22 and the air outlet 23, the rotary switch 26 provided at the lower end of the housing 21, and the air outlet 27 installed on the bottom of the housing 21 Battery 28.

Abstract

The invention relates to the field of daily hygienic products, in particular to a one-way air-delivery open mask. The mask comprises a mask body, a filtering air-delivery device and an air-delivery pipe, the air-delivery pipe is connected with the filtering air-delivery device (2) and penetrates through the mask body, a horn-shaped breathing window is arranged at the position, below the nostrils, of the air-delivery pipe and perpendicularly communicated with the part, inside the mask body, of the air-delivery pipe, and the flowing direction of airflow, inside the mask body, of the air-delivery pipe is perpendicular to that of airflow of the breathing window. An exhausting hole is formed in the tail end of the air-delivery pipe and is always in an open state. Due to the structure, inhalation resistance felt by a user is reduced to the maximum degree through the mask; the route and direction of airflow entering, exiting and flowing are fixed, the airflow inside the air-delivery pipe flows in a one-way mode all the time, the positions of airflow flowing into and out of the mask are different completely, waste gas exhaled by the nostrils can be taken out of the mask at once by the airflow inside the air-delivery pipe through the breathing window, no residual gas is formed inside the mask, and it is guaranteed that in any air environment, the wearer can breathe comfortably and healthily.

Description

Technical field [0001] The invention relates to the field of daily sanitary products, in particular to an open mask with one-way air transmission. Background technique [0002] Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, and when working in dust and other polluted environments, wearing masks has a very good protective effect. To exercise outdoors, in order to resist wind, sand and cold, or activities in an environment with air pollution, wearing a mask has a protective effect. Wear it in hospitals, construction sites, and dusty environments to prevent inhalation of germs and dust. However, the existing masks share the air intake and exhaust channels, and the exhaust gas discharged from the respiratory system cannot be discharged from the mask in time and is repeatedly inhaled, which affects the comfort of the mask and is not good for human health. Summary of the invention [0003] The purpose of the pre...
