As further improvement of the utility model, the suction-type medication unit is mineral salt deposit or medicinal salt deposit.
The utility model has advantages below compared with prior art.
The utility model is reasonable in design, can be single by the difference for adjusting air-breathing area according to different application targets
First syntagmatic, realize single filtration, purification air, suction-type medication unit or filtration, purification air and suction-type medication list
The requirement of the combination of member.Air enables to the suction mineral salt of user's convenience to be effectively improved to exhale by mineral salt deposit
Road system is inhaled, alleviates Respiratory symptoms, auxiliary treatment respiratory tract is uncomfortable.
Realize that multiple filtration purifies air when being applied in combination when filtration, purification air and suction-type medication unit, while just
The suction mineral salt of profit, medicinal salt deposit immerse the absorbent cotton layer of medicine and are effectively improved respiratory system, alleviate Respiratory symptoms,
Mouth mask person realization suction cleaning, high-quality air are treated to help to wear multi-functional salt, purifies respiratory system, auxiliary treatment respiratory tract
It is uncomfortable.
Mask body of the present utility model is flexible plastic material, for keeping multi-functional salt to treat between mouth mask and air
Sealing.Air-breathing area is that the cylindrical region on mouth mask is treated positioned at multi-functional salt, can be adjusted not according to use or therapeutic purposes
Same quantity and position, each one are treated on the downside of mouth mask or so two located at multi-functional salt when typically using, according to the group of different units
Conjunction relation, it can mainly be realized makes wearer suck cleaned air for filtering outside air, or makes to incorporate salinity in air,
Or improve respiratory system and experienced with breathing.Expiration zone has steam vent, the waste gas for human body discharge exhalation.Bandage is connected to mouth
Cover body both sides, ear both sides are fixed on for wearer.Inner side described in the utility model is close to the one of user's face
Side, the remote side of outside is relative usage person face.Expiration area of the present utility model is a check valve, and can only exhale to inhale
Gas.
Filter pulp layer material of the present utility model is synthetic fibers or glass fiber filter cotton, is crossed for preliminary in air filtering
Bulky grain thing, main filtration are more than 5 μm of dust particle.Contain a number of activated carbon granule thing inside active carbon layer, it is main
It is used to adsorb organic gas, stench and toxicity dust.HEPA screen packs use glass fiber filter paper to be used for as filter material
Filter >=0.3 μm of particle.
Suction-type medication unit is mineral salt deposit, absorbent cotton layer or the protector for avoiding mineral salt deposit, absorbent cotton layer from making moist.Ore deposit
Thing salt deposit is provided with the anticorrosion salt box of said minuscule hole using surface, facilitates air to be incorporated by and by salt in air.Salinity gasifies
Out, main component is the sodium chloride of fine particle shape, in addition containing trace elements such as selenium, iodine, calcium, potassium, magnesium, the sky after filtering
Gas makes mineral salt vaporization suck respiratory tract on a small quantity with air when human body sucks, and for improving respiratory system, nasal cavity etc. is played
Anti-inflammation and sterilization acts on.Absorbent cotton layer can be to carrying out suction-type medication to nasal cavity.
The warm-humid air that the purposes behaviour exhalation of the buffering area of protector is gone can be blocked by the check valve on the inside of buffering area,
But still have and enter buffering area on a small quantity.Because the transmission of pressure is faster than the transmission speed of steam, do not arrived in warm-humid air slow
When rushing the check valve on the outside of area, the check valve on the outside of buffering area has been switched off, and warm-humid air will retain here, be inhaled next time
It is sucked away during gas.Check valve is the breather valve of air flow in one direction, and air can only enter respiratory tract direction from the external world, film during air-breathing
Piece is opened, and the fresh air after above four layers filtering enters, and the gas pressure of characteristics of contaminated respiratory droplets closes diaphragm when exhaling,
To avoid the hot gas of characteristics of contaminated respiratory droplets by mineral salt or absorbent cotton liquefaction or damp failure.
According to the difference of fragrant atmosphere layer material, buffering area can fill spices.For improving the taste experience of air suction, carry
High experience sense.Fragrant atmosphere layer is used to improve taste experience during air suction, and its composition can be natural essence, fresh floral leaf or spices
Particle, such as peppermint or lemon particle.If nasal cavity is for essence allergy but want to enjoy the smell of spices, can be by fragrant atmosphere layer
It is substituted into after HEPA layers, sensitizer can be filtered but fragrance can also be retained, if but replaces to active carbon layer afterwards just without perfume
Gas;Before fragrant atmosphere layer can also being substituted into HEPA layers, after active carbon layer.
It is a kind of effective means for improving IAQ and respiratory disease using mineral salt that salt, which is treated, is promoted new old
Metabolism and bactericidal antiphlogistic effect, but existing salt treats the refined salt that mode actively breathes vaporization in the devices such as salt bag for people, one
As need to grasp, convenience deficiency.Or need the salt of specialty to treat room, expend quite high.Someone is by more work(in the prior art
Can salt treat the treatment of mouth mask and salt and combine, but because structure design is unreasonable, salt treatment layer moisture-sensitive when in use, it is impossible to when long
Between use, its cost height is so as to being not easy to promote.There is presently no a kind of multi-functional air and can that can purify to realize salt
Treat can the multi-functional salt that uses of convenience treat mouth mask.Multi-functional salt of the present utility model treats mouth mask and utilizes two check valves and buffering
The combination in area, avoid people exhalation warm-humid air make suction-type medication unit the salt of mineral rock stratum or the absorbent cotton of absorbent cotton layer by
Tide failure.The utility model can realize multiple filtration on the basis of salt treatment, realize that filter pulp, HEPA, activated carbon integrated
Filter.
