Technical Field

The utility model relates to an air filtration technical field, in particular to be used for PM2.5 to filter, prevent second-hand-cigarette, prevent nose plug formula filter equipment of pollen.

Background

In recent years, with the development of modern society, a great amount of pollutants in tail gas of production, life and automobiles are discharged, so that the air quality is continuously reduced, the haze phenomenon is increased, harmful substances, PM2.5 particles, dust and the like in the air are easily inhaled into the respiratory tract to cause harm, and people usually need to wear a mask or a nose plug. In addition, the user also has to wear a mask or nose plugs to prevent the harm of second-hand smoke and pollen allergy.

Because people are inconvenient to work and live due to long-term wearing of the mask, more and more users choose to use the nasal obstruction to prevent PM2.5, second-hand smoke and pollen from invading. However, the nasal plug filters currently on the market have two distinct disadvantages: 1. the plug and the nasal cavity can not be in close contact, so that air leakage is caused, and the filtering effect is influenced; 2. there is no distinction between exhalation and inhalation, and comfort is poor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a snuffle formula filter equipment to prevent that exogenous material from getting into the human body through the nasal cavity and causing the disease, improve filtration efficiency simultaneously, promote human comfort level.

In order to solve the above technical problem, an embodiment of the present invention provides the following solutions:

the utility model provides a nasal obstruction formula filter equipment, includes two continuous single nasal obstruction, single nasal obstruction includes shell, electrostatic filtration cotton layer, activated carbon filter layer and metal loop, electrostatic filtration cotton layer with the activated carbon filter layer sets gradually from inside to outside in the shell, the port department of shell sets up the metal loop, be provided with the breathing valve on the electrostatic filtration cotton layer.

Preferably, the main body of the housing adopts a two-layer tower structure.

Preferably, the bottom of the shell adopts a cross-shaped hollow structure.

Preferably, the electrostatic filter cotton layer provided with the breathing gas valve can be detached and replaced.

Preferably, the activated carbon filter layer is removable and replaceable.

Preferably, the breathing gas valve is arranged inside the layer of electrostatic filter cotton.

Preferably, the housing is transparent.

The embodiment of the utility model provides a beneficial effect that technical scheme brought includes at least:

(1) the breathing air valve is additionally arranged on the electrostatic filtering cotton layer, so that the resistance in breathing can be reduced, and the comfort of a human body is improved;

(2) the nasal cavity is laminated more in the shell design, and the metal loop struts the nostril slightly and fixes the device at the nasal cavity, increases the area of breathing in, has improved filtration efficiency.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

An embodiment of the utility model provides a nasal obstruction formula filter equipment, as shown in fig. 1 and fig. 2, nasal obstruction formula filter equipment includes two continuous single nasal plugs, and every single nasal plug includes shell 1, the cotton layer 2 of electrostatic filtration, activated carbon filter layer 3 and metal loop 4, and the cotton layer 2 of electrostatic filtration and activated carbon filter layer 3 set gradually in shell 1 from inside to outside, and the port department of shell 1 sets up metal loop 4, is provided with breathing valve 5 on the cotton layer 2 of electrostatic filtration.

In the embodiment of the utility model, considering that only air suction needs to be filtered, the air suction valve 5 is added on the electrostatic filtering cotton layer 2, which can reduce the resistance during air suction and increase the comfort of human body; the metal ring 4 slightly props open the nostril and fixes the device on the nasal cavity, and the device is tightly attached to the nasal cavity under the condition of increasing the air suction area, so that the filtering efficiency is improved.

Further, the main part of shell 1 adopts two-layer tower structure, and the bottom of shell 1 adopts cross hollow out construction, and the preferred transparent color that adopts of the colour of shell 1 forms the humanized design of laminating human nasal cavity, can effectively reduce gas leakage.

Further, as shown in fig. 2, the breathing air valve 5 is arranged on the inner side of the electrostatic filtering cotton layer 2, and the driving force required by the operation of the breathing air valve 5 is provided by the pressure difference generated by breathing.

The electrostatic filtering cotton layer 2 is a second layer filter screen of the device and mainly realizes the filtering effect on exogenous particles. The first layer of filter screen of the device is an active carbon filter layer 3 which plays a role in filtering larger particles and adsorbing part of organic compounds (VOC)_S) The function of (1).

Furthermore, the electrostatic filtering cotton layer 2 and the active carbon filtering layer 3 which are provided with the breathing air valve 5 can be detached and replaced, so that the service life of the device can be prolonged, and the cost can be reduced.

The metal ring 4 not only plays a role of slightly expanding the nostrils and fixing the device in the nasal cavity, so that the device cannot fall off, but also can make the nose look higher, erect and beautiful.

The utility model provides a snuffle formula filter equipment's working process as follows:

(1) inspiration state (working state): the breathing gas valve 5 on the static filtering cotton layer 2 is closed, and the active carbon filtering layer 3 and the static filtering cotton work together;

(2) and (3) an expiration state: the breathing air valve 5 on the electrostatic filtering cotton layer 2 is opened, the active carbon filtering layer 3 works, and the electrostatic filtering cotton does not work.

The utility model provides a snuffle formula filter equipment can filter a large amount of PM2.5 granule, pollen granule, filters and adsorbs most tar and nicotine, is particularly suitable for using for dislike wearing gauze mask or pollen allergic person in summer.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
