Referring to fig. 1 to 3, the air filtering nasal protector of the present invention comprises: a first component 10 and a second component 20.

Specifically, the first member 10 includes a first housing and a first filter member, the end face of the first filter member has mesh holes 11, the first filter member and the first housing define a first cavity 100 with one end open, and the first cavity 100 is filled with a filler for filtering air; the second part 20 comprises a second shell and two nose columns 21, the second shell is matched with the first shell, airflow channels are arranged in the nose columns 21 and are communicated with two sides of the second part 20, the nose columns 21 are used for being inserted into a nasal cavity, one side of the second part 20 is matched and connected with the open end of the first cavity 100, and the outline of the second shell is fitted with the outline of the nose of a person. When a user wears the air filtering nose protector provided by the embodiment of the utility model, the nose column 21 is aligned and inserted into the nostril of the user, and then the air filtering nose protector is sleeved on the nose of the user by utilizing the characteristic that the outer contour of the second shell is fitted with the contour of the nose of the user, so that an additional binding and fixing measure can be omitted. The air filter nose protector is inserted into the nasal cavity of a user through the nose post 21 to improve the tightness of the air filter nose protector, so that air sucked into the nasal cavity of the user needs to be filtered by the air filter of the embodiment of the utility model, and the aim of protecting the nasal cavity and the lung of the user is fulfilled.

Regarding the filler, the filler is used to effectively remove harmful substances such as smoke and microorganisms from the air passing through the mesh holes 11, and the filler includes but is not limited to activated carbon or aerogel material, and the user can select the corresponding filler according to the local air quality. In this embodiment, the filler is activated carbon for filtering soot particles of the air. As an improvement to this embodiment, make into the filler package with the filler, convenience of customers changes the filler.

Referring to fig. 1, the mesh holes 11 are used for filtering large particles in air, and the mesh holes 11 also increase the area of air exchange between the outside air and the air filtering nose protector, so that the air can uniformly pass through the air filtering nose protector, thereby improving the filtering efficiency and the service life of the filler.

Referring to fig. 2, regarding the second component 20, the upper portion of the outer contour is arc-shaped, and there is a groove 300 between the outer contour and the nose pillar 21 for receiving the nose, so that the second component 20 can be tightly attached to the nose of a person to ensure the air tightness of the air filtering nose protector of the embodiment of the present invention.

In a possible embodiment, the outer contour of the second housing is composed of a first curve segment, a second curve segment and a third curve segment which are smoothly connected end to end in sequence, and the span of the head-to-end point of the second curve segment is smaller than the span between the starting point of the first curve segment and the end point of the third curve segment.

It should be appreciated that the air filtering nasal protector of the embodiment of the present invention is made of soft and light material, which can make the external contour of the second component closely fit with the nose of the user, and avoid uncomfortable feeling for the user.

In one possible embodiment, the first and

second components

10, 20 are made of a medical grade plastic. Wherein, the medical plastic is medical PVC which has chemical corrosion resistance, no toxicity and low cost. The air filtering nose protector disclosed by the embodiment of the utility model is designed on the structure of the nose protector and selects the material of the nose protector, so that the air filtering nose protector can be attached to the nose of a person through the nose post 21 and the second shell to realize the wearing of the air filtering nose protector, binding bands or other additionally arranged fixing structures are omitted, and the discomfort of a user caused by the fixing structures such as the binding bands when the user wears the air filter is relieved. In other words, the air filtering nose protector provided by the embodiment of the utility model is additionally worn on the nose and has the characteristics of small size and light weight.

In a possible embodiment, the open end of the first cavity 100 is provided with an air filter membrane (not shown in the figures). An air filtering membrane is arranged at the open end of the first cavity 100, and air entering the first part 10 is further filtered, so that the filtering effect is ensured. As for the air filtration membrane, the air filtration membrane may be a meltblown or a glass fiber filter.

In a possible embodiment, the air filter membrane is removably mounted to the first part 10. Wherein, set up an annular lasso that matches with the open end of first cavity 100, through with air filter membrane cover on the open end of first cavity 100, make air filter membrane demountable installation, convenience of customers changes air filter membrane.
