Description
Technical field
It is the present invention relates to a kind of wearable air cleaning unit, in particular to a kind of to adjust temperature and humidity without consuming energy
Wearable air cleaning unit.
Background technique
With the development of economy, air pollution is more serious, currently, China oneself have more than 80% city haze and take place frequently,
Oneself is encroached on the health of compatriots, seriously affects quality of life, or even threatens the existence of the mankind.Sky wearable with oneself
Air purifying apparatus undoubtedly becomes the main means of reply.
The closed environment that current wearable air purifier is built processing characteristics of contaminated respiratory droplets high Hot wet air heating with
And there are many defects for the aerial temperature and humidity parameter of sucking.The gas of physiological metabolism based on human body, characteristics of contaminated respiratory droplets is basic
Stablize at 32 DEG C, and humidity is about 34mg/L, relative humidity is close to 100%.And typical surrounding air is at 20 DEG C or so, and
Absolute humidity 10mg/L, relative humidity is close to 40%, but outdoor varying environment and the temperature of weather can be wider at -10 DEG C to 35 DEG C
Range, humidity also have large change.The wet exhaled gas of high fever at least causes following problem, and the hot gas of exhalation is cold to the cold
Solidifying, so that closed environment becomes bored wet, vapor is easy to soak the filter material of clarifier, more sulks or even failure, comfort level
Decline immediately；If wearing spectacles, the hot gas of exhalation also results in eyeglass and obscures, and influences safety.Further, environment sucks
There are biggish differences for air themperature and humidity parameter and a home from home or even indoor environment, cause to hinder to the eupnea of human body
Hinder and difficult, and further reduced the comfort level of people's breathing, or even damage.In addition, passive conditioning measure uses
Hot and humid area material is alternately through air-breathing and expiration, it cannot be guaranteed that effect, can only be used as ancillary measure, air-breathing and expiration are completely mixed
It closes, movement disorder simultaneously mutually pollutes；Active temperature adjustment measure mainly uses electric drive heating and cooling, needs additional energy source, battery
Weight is big, and human body weight bearing increases, and reduces comfort level, is not suitable for body walking or motion state is worn.
Summary of the invention
Present invention aim to address the defects of the prior art, the high fever humid gas of characteristics of contaminated respiratory droplets are efficiently utilized, to change
The temperature and humidity parameter of kind air-breathing, the temperature and humidity for eliminating environment is uneven, provide it is a kind of without energy consumption i.e. temperature-adjustable with
The wearable air cleaning unit of humidity.

The hygroscopic material built in the exhalation passages of device, the hygroscopic material can be moisture absorption exothermic material and moisture absorption heat-absorbing material,
When middle moisture absorption exothermic material is lower than suction temperature for environment temperature, wherein moisture absorption heat-absorbing material is higher than air-breathing for environment temperature
When temperature, it can also be mixed in a certain ratio use, for certain environment temperature, the temperature and humidity indicator is temperature and humidity color
Indicating adhesive film is placed in the mask and shows position close to nose, indicates whether that suction temperature and humidity are suitable in human body
Suitable temperature and humidity parameter area.
Further, the regulating valve can be made of the overlapped arc shaped blade of multi-disc, by rotary motion annulus
The clutch for changing blade changes center bore, and then adjusts circulation area.
Further, the heat moisture exchanger is preferably the heat exchanger of spiral plate type, and partition is metal foil material, every
Micropore is disposed on plate as wet interchange channel, inside forms two spirality channels, wherein a channel spiral, as air-breathing
Channel, surrounding air make helical flow, enter from central inlet, and go to periphery, outer outlets outflow, another channel by center
As exhalation passages, the hygroscopic material is filled in inside, exhales and makees axial flowing, from close to one side entrance of mouth to environment side
Cross flow one is made in output flow, air-breathing and expiration.
Further, the workflow using above-mentioned wearable air cleaning unit is as follows, the high humidity of human exhaled breath's exhalation
Hot gas flows through the hygroscopic material of the heat moisture exchanger exhalation passages, absorbs and releases heat, and through the check valve
Environment is breathed out, meanwhile, surrounding air enters the hot and humid area through the filter filtration, purification, and by the check valve
The air intake passage of device, carries out hot and humid area, and such as temperature and humidity indicator instruction air-breathing is not at the suitable temperature and humidity ginseng of human body
Number ranges, by the hot and humid area area of heat moisture exchanger described in the adjusting valve regulation until reaching relatively comfortable warm and humid of human body
Parameter is spent, the surrounding air for completing purification and temperature and humidity adjustment flows out into human body completion air-breathing through the outlet of air intake passage.
The beneficial effects of the invention are as follows inventions due to taking above technical scheme, has the advantage that of the invention efficient
Using the high fever humid gas of characteristics of contaminated respiratory droplets, the adverse effect of exhaled gas had not only been eliminated, but also can be used for adjusting suction temperature and wet
Degree；Realize that temperature and humidity is adjusted using moisture absorption heat-absorbing material and moisture absorption exothermic material and highly hygroscopic material, without energy consumption, again
Amount is light；Realize that temperature and humidity is adjusted using heat moisture exchanger, light, efficient, embedded hygroscopic material is replaceable, conveniently, fits
Answering property is good；The exchange area of heat moisture exchanger is adjustable, adapts to Various Seasonal, varying environment and human body is static and movement occasion
Load betters meet requirement；Heat moisture exchanger is dividing wall type, prevents air inlet and exhaust from interfering with each other and polluting；Utilize temperature
Quick material and humidity-sensitive material, by color indicate air-breathing temperature and humidity state, intuitively, conveniently, price it is low；Secure air-flow disengaging people
The glide path of body and direction, suction end is on the upside of nose and avris, and at mouth, position is different at expiration end, prevents from interfering, residue gas
Body is few；Check valve is placed on ambient side, and the surge volume of gas chamber is big, can prevent internal exhale from mixing and interfering with each other with air-breathing；
The present invention carry and it is convenient to wear, without energy consumption can temperature and humidity adjustment, avoid traditional mask sulks and waste filter material
The problems such as matter, the case where also avoiding existing portable air cleaning unit discomfort resultant motion.System weight is light, at low cost,
Enjoy comfortable breathing.
