Embodiment 1

[0012] Such as figure 1 , figure 2 , image 3 As shown, the one-way air transmission open mask includes a mask body 1, a filter air delivery device 2, an air delivery pipe 3 connected to the filter air delivery device 2 and passing through the mask body 1, and the air delivery pipe 3 is located below the nostrils and is provided with a horn Shaped breathing window 4, described trumpet-shaped breathing window is vertically communicated with part air delivery pipe 3 in mouth mask body 1, guarantees that the air flow direction of trumpet-shaped breathing window air flow is perpendicular to the air flow direction of air delivery pipe 3, forms an air curtain, and described air delivery The air flow direction of the air pipe 3 in the mouth mask body 1 is perpendicular to the air flow direction of the breathing window 4, and the end of the air pipe 3 is an exhaust hole 31, which is always in an open state. The filtering air delivery device 2 adopts a miniature electric fan 22 to d...

Embodiment 2

[0014] Such as figure 1 , figure 2 As shown, the air delivery pipe 3 is located in the mouth mask body 1 and is provided with an air flow distribution box 32, the thickness of the air flow distribution box 32 is greater than the diameter of the air delivery pipe 3, and the trumpet-shaped breathing window 4 is vertically installed in the air flow distribution box 32 The inner side, and communicated 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 disposed in the housing 21, two air inlets 23 located on both sides of the fan 22 and located on the housing 21, and two air inlets 23 located at the air inlet 23. Filter membrane 24, be located at the air outlet 27 on the housing 21, be located at the anion generator 25 between fan 22 and air outlet 23, be located at the knob type switch 26 of housing 21 lower end, be installed in housing 21 bottoms 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 a one-way air transmission open mask. Background technique [0002] Masks have a certain filtering effect on the air that enters the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good protective effect when working in a polluted environment such as dust. When exercising outdoors, in order to resist wind and sand and cold, or move 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. But existing mouth mask all adopts air intake and exhaust channel to share, and the waste gas discharged from respiratory system cannot discharge mouth mask in time, is sucked repeatedly, thereby affects the comfortable sense of mouth mask use, is also unfavorable for human health, and. Contents of the invention [0003] The ...
