Technical Field

The utility model relates to the technical field of hygienic products, in particular to an air filtering nose mask.

Background

With the development of industry, air pollution is increasingly serious, and the living standard of people is affected.

At present, a common air filtration method is to wear a mask, but the mask can simultaneously shield the mouth and nose of a human body when being worn, and the shielded face area is easily in a high humidity environment, so that skin problems such as acne growth, allergy and the like are caused.

Simultaneously, under many circumstances, people all only use the nose to carry out the air exchange, for example, when walking alone, during workshop work, wear the gauze mask under this kind of condition and influence the comfort level, and be unfavorable for face identification.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: the air filtering nose mask is provided for overcoming the defect that the mouth and the nose of a mask need to be shielded simultaneously and considering that most people breathe through the nose.

In order to realize the purpose, the utility model discloses a technical scheme be:

an air filtering nose mask comprises a face plate and a fixing pad; the panels comprise an outer panel and an inner panel; the outer panel is provided with a plurality of outer air holes, the inner panel is provided with a plurality of inner air holes and a plurality of bottom air holes, the bottom air holes are upwards communicated with the inner air holes, and one-way air outlet assemblies are arranged in the bottom air holes; a filter sheet placing groove is formed between the outer panel and the inner panel, the outer air hole and the inner air hole are respectively communicated with the filter sheet placing groove, and a filter sheet placing opening is formed in a panel above the filter sheet placing groove; the fixed bolster is the sunk structure who corresponds the people's nose shape, just the fixed bolster with one side that the interior panel kept away from the cassette standing groove is connected.

It can be understood that the utility model discloses an air filtering nose cup is when the user breathes in, and gas loops through outside gas pocket, cassette standing groove and inboard gas pocket entering human body, and when exhaling, gas then mainly discharges through the bottom side gas pocket with inboard gas pocket intercommunication, and need not through the filter screen again, and the very big efficiency of taking a breath that has increased of this kind of design has shortened the dwell time of the high humid gas of exhalation in the nose cup.

Meanwhile, the filter piece placing groove is used for placing the filter piece, and the filter piece placing opening is used for placing the filter piece in the filter piece placing groove, so that the time for replacing the filter piece is greatly shortened.

Further, the inner side air holes are of a rectangular structure or an oval structure, and are distributed on the inner panel in a single row.

It can be understood that the inner side air holes are distributed in a single row, so that the bottom side air holes are communicated with all the inner side air holes upwards, and the inner side air holes are preferably selected to be rectangular or elliptical, because the rectangular or elliptical structure is convenient for realizing the inner side air holes with the largest area on the inner panel, and the ventilation efficiency is increased.

Further, the unidirectional air outlet assembly comprises a gasket and a fixing column; the bottom side air hole is a stepped hole, the unidirectional air outlet assembly is arranged at the step of the bottom side air hole, the fixed column is positioned in the bottom side air hole, one end of the fixed column is connected with the gasket, the other end of the fixed column is connected with the inner panel through a plurality of radial plates, and the fixed column and the radial plates are used for fixing the gasket; when a user inhales, the gasket is tightly attached to the step of the bottom side air hole, and when the user exhales, the gasket is far away from the step of the bottom side air hole.
