Abstract
The present invention provides a kind of filtering type breathing mask, including mask body and filtering body, it is provided with the appearance air cavity for being suitable for covering mouth and nose setting on the inside of mask body, is provided with exhaust outlet on the wall surface for holding air cavity；It is internally provided with fan and filter element in filtering body, wherein filter element is arranged on the inlet channel of fan, is connected with driving mechanism with fan；It is provided with and communicated with tracheae with the outlet passageway of fan, the outlet side of the tracheae is connected to setting with the appearance air cavity of the mask body.The application reduces the weight of mask body, and solve the problems, such as to influence human comfort because fan noise is larger by the way that mask body and filtering body to be provided separately.And the problem of due to the covering mouth and nose setting of the appearance air cavity of the filter mask in the application, this allows for the surrounding space that purification air can be full of nostril, avoids sucking pollution air caused by not being bonded because of the outlet of purification air with nostril.
Description
Technical field
The invention belongs to air purification fields, and in particular to one kind can filter the active filtering breathing of tiny particles content
Mask.
Background technique
Haze is a kind of weather phenomenon, refers to that a large amount of subtle dry grit such as dust uniformly swim in air, makes sky
Gas is muddy, the visual field obscures and leads to visibility deterioration.Serious influence can be caused to human health by being chronically exposed in haze, be had
Studies have shown that respiratory system of the haze to human body, cardiovascular system will cause huge injury, or even there is also carcinogenic hidden
Suffer from, therefore when haze weather is gone out, more and more people's selection carries out safeguard procedures using filter mask.
In the prior art, Chinese patent literature CN20357717U discloses a kind of mask for anti-particulate matter, the mask
Mask body and mask filter cartridge including connection setting；Wherein, the mask body include cover mouth and nose setting cover with
And the breathing part of setting is connect with the cover, the both ends of the cover have been connected by a snap respirator belt respectively；It is exhaled described
It inhales and is provided with spiracle on part.When in use, the air of user's incoming call first passes through filter cartridge and is filtered to be entered back into the mask
In the cover, so as to effectively filter out the fine particle in air, when in dust work place in use, can be effective
Prevent silicosis.In addition, in the prior art, Chinese patent literature CN103868162A is also disclosed in order to mitigate the resistance of breathing
The main body of a kind of portable air purifier being provided with blower, the air purifier is equipped with air inlet and air outlet, in institute
Body interior is stated equipped with blower and air cleaning portion, under the action of the blower, air enters from the air inlet, by institute
It is discharged after stating air cleaning portion by the air outlet.For the ease of carrying, the main body of the air purifier is at least partly in
Around shape, it is set to encircle positioning in the neck of user, when the air purifier is placed on face, air outlet is close
The nostril of wearer is arranged.
Above-mentioned air purifier in the prior art effectively reduces the resistance of human body respiration, still by setting blower
Since there are a certain distance apart from human body nostril for air purifier air outlet, rather than fit closely nostril setting, therefore, people
Body other than sucking purifies air, can also suck certain pollution air in breathing；Further, since above-mentioned air purifier is set
Set blower, the weight that this allows for mask is larger, and due to blower at work motor rotation can generate it is certain
Noise, even if noise is very faint, is used for a long time if blower is too close apart from human ear, uncomfortable feeling can be also brought to human body.
Summary of the invention
The invention solves existing for filter mask in the prior art between air outlet and nostril there are distance, be easy
Lead to sucking pollution air, and since the setting of blower leads to the problem that mask weight is larger, ear's noise is larger.And then it provides
A kind of purification air can surround the filtering type breathing mask of nostril setting, lighter in weight and noiseless pollution.
The application solves the technical solution that above-mentioned technical problem uses are as follows:
A kind of filtering type breathing mask, comprising:
