In order to achieve the above object, the utility model provides an keep apart gauze mask of virus, bacterium, it realizes through following technical scheme:
the utility model provides a keep apart gauze mask of virus, bacterium, includes the gauze mask body and fixed band, and there is a transparent window above the gauze mask body, and the gauze mask is internal to include one and to filter the storehouse, its characterized in that filter the storehouse and pack the ceramic particle one of infiltrating sterilization, disinfection liquid and infiltrate sterilization, disinfection liquid's ceramic particle two. The ceramic particles I and the ceramic particles II are foamed porous ceramics. The first ceramic particle is soaked in a sodium hydroxide solution, and the second ceramic particle is soaked in a potassium permanganate solution. The ceramic particles I and the ceramic particles II (6) in the filter bin are separated by a ventilating partition plate. And a circle of sealing ring is arranged at the edge of the mask body and the edge of the transparent window. And a first dustproof spunbonded fiber layer is arranged on the inner side of the filter bin. And a second dustproof spunbonded fiber layer is arranged on the outer side of the filter bin. The inner side of the filter bin is provided with a porous inner cover.
Such a mask:
1. the foam porous ceramic particle filler in the filter element is soaked by disinfectant, so that bacteria and viruses in the air can be killed and harmful gases in the air can be decomposed in the modes of adsorption, decomposition and killing.
2. The disinfectant can be liquid such as sodium bicarbonate or potassium permanganate which can kill bacteria and viruses, and the sodium bicarbonate or potassium permanganate can also decompose main harmful gases such as sulfur dioxide and nitric oxide in haze: SO2+ NaOH = NaSO3+ H2O, 5SO2+2KMnO4+2H2O = K2SO4+2MnSO4+2H2SO 4.
3. The filter element filler adopts foam porous ceramic particles with large specific surface area, which can not only ensure a large enough ventilation section and reduce the breathing resistance, but also increase the specific surface area of the filter element filler contacted with air, so that the channel of air inlet flow is narrow, tortuous and long, and better adsorbs and kills bacteria and viruses in air spray and aerosol and decomposes harmful gas in air.
4. A transparent and sealed eye protection window is arranged above the mask, so that bacteria, viruses and harmful gases can be prevented from invading from eyes.
6. The inner side of the filter bin is provided with a porous inner cover. The foam porous ceramic particles can be conveniently put in and taken out; the filter element filler is convenient to wash, burn and disinfect, and disinfectant is soaked again; the use cost is conveniently reduced, and the device can be repeatedly used.
In this way, it is possible to realize: can kill bacteria and viruses. The virus and bacteria are separated between the patient and the air, and the healthy person is prevented from being infected by the virus and bacteria in the air. The mask can be detached and washed for reuse.

Detailed Description
The following describes the present invention in detail with reference to fig. 1.
Fig. 1 is a schematic side sectional view of an embodiment of a mask for killing viruses, bacteria and decomposing harmful gases. The utility model provides an keep apart gauze mask of virus, bacterium, includes the gauze mask body 1 and fixed band 2, and there is a transparent window 3 above the gauze mask body, and the gauze mask is internal to include one and to filter storehouse 4, its characterized in that filter storehouse intussuseption and soak ceramic particle one 5 and soak ceramic particle two 6 of disinfecting, disinfecting liquid. The ceramic particles I and the ceramic particles II are foamed porous ceramics. The first ceramic particle is soaked in a sodium hydroxide solution, and the second ceramic particle is soaked in a potassium permanganate solution. The first ceramic particles 5 and the second ceramic particles 6 in the filter bin 4 are separated by a ventilating partition 7. And a circle of sealing ring 8 is arranged at the edge of the mask body and the edge of the transparent window. And a first dustproof spunbonded fiber layer 9 is arranged on the inner side of the filter bin 4. And a second dustproof spunbonded fiber layer 10 is arranged on the outer side of the filter bin 4. The inner side of the filter bin 4 is provided with a porous inner cover 11.
The specific technical indexes are that according to the national standard GB 2626-2006, the cross-sectional area of the filtering bin of the mask for killing bacteria and preventing viruses is square 8 multiplied by 10 square, the length is 0.05m, the granularity of the foam porous ceramic particles is as follows: d90 is more than 0.5mm and less than 2 mm. Porosity is more than 50%, and porosity is more than 50 nm. The specific surface area is more than 10 square meters per gram. Under the air flow of 85L/min, the respiratory resistance is less than 350Pa, and the expiratory resistance is less than 250 Pa. The dustproof spunbonded fiber layer has the fiber diameter of 1-10 mu m.
According to the above-described embodiments, since the number of the gaps of the ceramic foam particles is large although small, the resulting breathing resistance is small; the dustproof spunbonded fiber layer has large ventilation area and small breathing resistance; the breathing is smooth by adopting the exhaust check valve.
