Description

A portable anti-fog device

technical field

The invention relates to a personal anti-haze product, in particular to a nasal congestion type anti-fog device with a one-way breathing valve.

Background technique

Recently, serious smog particle pollution has occurred in our country, especially in autumn and winter, smog pollution seriously affects people's quality of life. Although the existing masks on the market can play a good anti-smog effect, there are still some defects in the process of use, which need further improvement, as follows:

1. Part of the fit between the mask and the face is not tight, especially in the area near the nose. The moist air exhaled by the human body will be discharged upward along the gap between the mask and the face. If the user wears glasses, the exhaled water vapor will be very fast. Condensation on the glasses will cause blurred vision. Even if the gap is reduced by adding plastic aluminum strips, the effect is still unsatisfactory, and moisture will remain in the filter layer, which can easily cause bacteria to grow;

2 Ordinary masks, the actual effective use position is only a small filter layer near the mouth, the filter layer on the cheeks is actually not used, and when the filter layer of the mouth is polluted, the mask needs to be replaced, which leads to The use efficiency of the filter layer is very low, and the service life of the mask is greatly shortened.

3 Another neglected problem is that in addition to the respiratory system, the hair also absorbs a large amount of smog particles. Since the hair itself has a large specific surface area and many small gaps, when the hair of the human body is exposed to the smog environment on a large scale, the smog particles are very easy to attach, which is not conducive to hygiene and may cause potential harm to the human body.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art and provide a portable anti-fog device, which can avoid the influence of exhalation on the glasses, protect the hair from pollution, and improve the use efficiency of the filter layer.

To achieve the above object, the present invention adopts the following technical solutions:

A portable anti-smog device includes a filter device and a breathing device, the filter device and the breathing device are connected through a hose, and the filter device is fixed on a lightweight foam helmet.

The filtering device comprises a filter mesh support layer, a filter layer and a lightweight foam inner shell, a filter layer is arranged between two filter mesh support layers, and the filter mesh support layer and the filter layer are fixed on the lightweight foam inner shell.

The support layer of the filter screen is a grid made of plastic material.

The filter mesh support layer is fixed to the lower lightweight foam inner shell by means of glue.

The breathing device is a nasal catheter, the nasal catheter includes a folded hose, an elastic hose, two single-way breathing valves, two porous nasal plugs, the elastic hose is connected with the folded hose, two one-way breathing valves and an elastic The hose is the connection, and the flexible hose end connects the two porous nasal plugs.

One end of the folded flexible hose is glued and fixed on the inner side of the ear structure on both sides of the lightweight foam helmet.

The section of the elastic hose is designed as a semicircle.

The two one-way breathing valves are located at 4-5 cm on both sides of the porous nasal plug.

The porous nasal plug is hollow and porous and can be directly inserted into the nasal cavity.

The respiratory filtering device is made of polyethylene.

The present invention has the following technical effects:

1. The present invention adopts the method of nasal catheter inhalation and oral cavity direct exhalation, effectively avoiding water vapor from contaminating glasses and masks.

2. The filter layer of the present invention is no longer close to the mouth, but at the two positions above the head, the use area of the filter layer is increased, the efficiency is improved, and the service life of the filter layer can be extended at the same time.

3. The use of the present invention takes into account the protection of the hair and prevents the hair from being polluted by smog.

detailed description

A portable anti-smog device includes a filter device and a breathing device, the filter device and the breathing device are connected through a hose, and the filter device is fixed on a lightweight foam helmet. The filtering device comprises a filter mesh support layer, a filter layer and a lightweight foam inner shell, a filter layer is arranged between two filter mesh support layers, and the filter mesh support layer and the filter layer are fixed on the lightweight foam inner shell. The support layer of the filter screen is a grid made of plastic material. The filter mesh support layer is fixed to the lower lightweight foam inner shell by means of glue. The breathing device is a nasal catheter, the nasal catheter includes a folded hose, an elastic hose, two single-way breathing valves, two porous nasal plugs, the elastic hose is connected with the folded hose, two one-way breathing valves and an elastic The hose is the connection, and the flexible hose end connects the two porous nasal plugs. One end of the folded flexible hose is glued and fixed on the inner side of the ear structure on both sides of the lightweight foam helmet. The section of the elastic hose is designed as a semicircle. The two one-way breathing valves are located at 4-5 cm on both sides of the porous nasal plug. The porous nasal plug is hollow and porous and can be directly inserted into the nasal cavity. The respiratory filtering device is made of polyethylene.

The invention provides a nasal congestion anti-fog device with a single breathing valve, which can overcome the fog problem of the mask, can significantly increase the use area of the filter layer, and can provide additional protection for the hair.

The top layer of the device is the first layer of plastic grid shell 4, polyethylene plastic, with grid-like holes above, and ear-like shape designs 6 on both sides for fixing the filter screen. There is a layer of filter screen 5 under the plastic grid shell, which mainly plays a filtering role. Below the filter screen is a second layer of plastic grid shell, which is the same in shape and size as the plastic grid shell of the first layer. Between the two layers of plastic grid shells The filter is mechanically sandwiched in the middle by press fit. If you want to replace the filter, you need to separate the two layers of plastic mesh shells, remove the old filter, and mechanically press the new filter on the two layers of plastic mesh. the middle of the shell. Wherein the flexible hose 7 is folded, and an open end is fixed on the inner sides of the ear-type structures on both sides of the lightweight foam helmet by gluing. The folding hose is mainly used to adjust the length when wearing. The cross section of the elastic hose 1 is designed in a semicircle to achieve sufficient ventilation and better fit the face. Wherein the operating principle of the one-way breathing valve 3 is (taking the left as an example) when the air is inhaled from left to right, the light plastic ball 8 in the middle is blown up and placed on the hollow plastic fixed grid 9 at the back, and the air flows from the left to the right. The air flows through the grid; when the air is exhaled from right to left, the light plastic ball in the middle is blown up and blocked between the two fixed plastic short plates 10, the duct is sealed, the air is not circulated, and single-phase breathing is achieved. The role of effectively ensuring that the air you breathe is filtered.

When the user wears it, first put on the helmet, fit the light foam layer to the head as much as possible, and place the ear-shaped design devices on both sides of the helmet behind the ears to achieve a comfortable and beautiful effect, and then adjust the folded hose to Appropriate length, then place the two porous nasal plugs 2 at the front end of the elastic hose in the two nostrils of the nose, adjust the folded hose again and place the flat surface of the elastic hose near the face (because the section of the elastic hose is a semicircle), that’s it.
