The utility model discloses a fan is installed in the ear muff, and it is fixed that the ear muff passes through the head fixation clamp, and it is convenient comfortable to wear, and the fresh air after the filtration passes through the air duct and carries the nasal cavity, avoids the straight mouthpiece nose of gas, and the gaseous of exhalation is discharged from the lower part opening, has avoided the interior hot -damp gas gathering of gauze mask, is particularly suitable for hazy weather and dyspneic patient and uses.
Description
Technical field
The utility model is related to respiratory protection equipment field, in particular to a kind of ear-shield type non-resistance breathing equipment.
Background technology
With the continuous propulsion of process of industrialization, industrialization and urbanization drastically causes the energy rapidly to consume, population is high
Degree aggregation, environmental destruction, air quality drastically declines, and with the deterioration of air quality, haze weather is increasingly becoming life
Normality, haze the inside containing various harmful fine graineds, noxious material up to kind more than 20, its content is normal atmospheric water
Tens times of drop, the harm to human health is huge.
In order to avoid the harm of haze weather, most effective and simple method is exactly to wear mouth mask, at present mouth on the market
Cover be present when wearing more, and the power for crossing air filtering is breathed by the active of people and provided, and breathing is easily felt when wearing
Not smooth, and the gas of exhalation is not easy outwards to distribute, staying in mouth mask becomes moist through mouth mask to make us not feeling well.
The utility model patent of Patent No. CN105380316 discloses one kind and can supplement fresh air and remove human body exhales
The mouth mask of the hot moisture for going out, fan is arranged on mouth mask, realizes that ear suspension type is worn by frenulum, and this mode has following asking
Topic：First, the weight of fan can cause mouth mask sagging, wear uncomfortable；Second, the wind of fan blowout faces nose and mouth directly, right
The patient for having respiratory disorder can cause expiratory dyspnea；3rd, anterior grand swollen projection hinders attractive in appearance.
Utility model content
Main purpose of the present utility model is the problem existed for existing mouth mask, there is provided a kind of comfortable wearing, air
Good filtration effect, both artistic and practical ear-shield type non-resistance breathing equipment.
To achieve these goals, the utility model uses following technical scheme：
A kind of ear-shield type non-resistance breathing equipment, including head geometrical clamp and the ear for being symmetricly set in head geometrical clamp two ends
Cover, the air outlet of two earmuffs is provided with the wireway being connected with breathing mask, battery is provided with head geometrical clamp, in two earmuffs
The fan being connected with battery is provided with, the air inlet side of fan is provided with air-purifying piece.
Further, the ear-shield type non-resistance breathing equipment also includes elastic reducing-fixing band, elastic reducing-fixing band two ends difference
It is connected with two earmuffs, for the breathing equipment to be fixed on into back of head, prevents from dropping；
Further, breathing mask is semi-enclosed, and up-narrow and down-wide, covering nose and mouth, top is stuck on the bridge of the nose, bottom
It is provided with opening；
Further, the fan is vortex flow fan, and vortex flow fan belongs to centrifugal fan, can be under smaller space hold
The bigger air quantity of output；
Further, the air inlet that wireway is connected on breathing mask is located at nasal cavity both sides, passes through by the air for purifying
Wireway is input into breathing mask, and convenient use person has a breath of fresh air.Nasal cavity is clean all the time under the pressure effect that gas is produced
Net air is surrounded, and the waste gas of exhalation is discharged by mask lower ending opening；
Further, air-purifying piece uses HEPA filter screens；
Further, it is provided with noise reduction layer on the inside of earmuff.
The utility model has the advantages that：Fan of the present utility model is arranged in earmuff, and earmuff passes through head
Geometrical clamp is fixed, and wears Energy and comfort, and the fresh air after filtering is transported to nasal cavity by wireway, it is to avoid gas blow-through mouthful
Nose, is particularly suitable for patient and uses, and the gas of exhalation is discharged from lower openings, it is to avoid hot and humid gas aggregation in mouth mask.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model use state side view；
Wherein, above-mentioned accompanying drawing is marked including the following drawings：1st, head geometrical clamp；2nd, earmuff；3rd, wireway；4th, respiratory surface
Cover；5th, fan；6th, air-purifying piece；7th, elastic reducing-fixing band；8th, noise reduction layer.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of ear-shield type non-resistance breathing equipment, including head geometrical clamp 1, head geometrical clamp two ends are symmetrical
Earmuff 2 is provided with, the air outlet of two earmuffs is provided with the wireway 3 being connected with breathing mask 4, electricity is provided with head geometrical clamp
Pond, is provided with the fan 5 being connected with battery in two earmuffs, the air inlet side of fan is provided with air-purifying piece 6, earmuff it is interior
Side is that the side of ear contacts is provided with noise reduction layer 8.
Due to space limitation in earmuff, fan uses vortex flow fan, vortex flow fan to belong to centrifugal fan, can be in smaller sky
Between take the bigger air quantity of lower output；Breathing mask is semi-enclosed, up-narrow and down-wide, covering nose and mouth, and top is stuck in the bridge of the nose
On, bottom is provided with opening, and the air inlet that wireway is connected on breathing mask is located at nasal cavity both sides, passes through to lead by the air for purifying
