Description

A kind of actively air admission type mask

Technical field

The present invention relates to a kind of mask, be specifically related to a kind of actively air admission type mask.

Background technology

Fine particle, also known as PM2.5, refers to the surrounding air air kinetics equivalent diameter particulate matter less than or equal to 2.5 microns, and the particulate matter of 10 �� m diameter is usually deposited at upper respiratory tract, the be deep into bronchioles of less than 2 ��m and alveolar. Fine particle enters human body after alveolar, directly affects the ventilatory function of lung, makes body easily be in anaerobic condition. Compared with thicker Atmospheric particulates, PM2.5 is owing to its particle diameter is little, area big, activity is strong, easily attach the attribute of poisonous and harmful substance, and its time of staying length in an atmosphere, fed distance are remote, thus the impact of health and atmosphere quality is bigger

Being increasingly becoming, along with PM2.5 index, the focus that the whole nation common people pay close attention to, the most general selection of people is to go out to put on mask, intercepts the Inhalable Particulate impact on lung in the way of the easiest. There is mask mainly include air filtration, sealing and the functional unit such as wear, on the market the existing mask with haze function be no lack of have air cock, with multi-filtering, current patent application and commercially available prod have existed some technical schemes with fan, turbofan really, but currently existing scheme is not fully solved problems with yet: if people's outside pressure when breathing is strong more than intrapulmonic pressure, sense of feeling oppressed can be produced; Mask has bacteria breed at inwall after use repeatedly, to avoid in incoming call body when reusing, and reuses rate variance; When meeting the demand of user individual, often there is wearing the problem of inconvenience, and the filter effect of mask can be affected.

Detailed description of the invention

Below in conjunction with drawings and Examples, technical scheme is described in further detail.

A kind of actively air admission type mask as shown in Figure 1, mainly include mask main body 1 and the filtration being located in mask main body 1 and active air inlet assembly 2, mask main body 1 realizes quick donning by wearing assembly, wear assembly and mainly include elastic threads 3 and mounting joint 4, mask main body 1 be respectively provided on two sides with elastic threads 3, one end of mounting joint 4 is fixed therein in the elastic threads 3 of either side, and the other end leaves hook, for catching on the elastic threads 3 of opposite side, thus realizing quick donning.

The structure of filtration and actively air inlet assembly 2, with further reference to Fig. 2, mainly includes shell body 5, basis 9 and is sequentially placed into active carbon filter net 6 therebetween, sea handkerchief filter screen 7 and fan and energy module 8 along mask thickness direction from outside to inside; Wherein:

Fan and energy module 8 include fan and provide rechargeable battery and the fan control unit of the energy for fan, according to the intrinsic pressure powerful little dynamic adjustment rotation speed of the fan of mask, can change pressure pressure inside and outside mask, it is achieved actively air inlet; Specifically:

Fan control unit detects the air pressure at the passage place of its front end, by controlling to flow to the electric current of fan, thus adjusting the rotating speed of fan, namely adjusts the duty of fan according to air pressure; Specifically:

If the air pressure at passage place is higher than a certain setting high threshold, then fan control unit judges that user is in expiration state, reduces the air pressure at passage place now by reduction rotation speed of the fan, makes user exhale smooth and easy;

When the air pressure at passage place is lower than a certain setting Low threshold, then fan control unit judges that user is in suction condition, improves the air pressure at passage place now by increase rotation speed of the fan, makes user's air-breathing smooth and easy.

Concrete air pressure set threshold value by experiment, the science data of expertise and specialty pneumatology determine. It can be seen that the invention enables the air pressure at passage place can adjust according to the respiratory movement of wearer, it is ensured that wearer breathes air cleanliness that is smooth and easy and that suck.

By after shell body 5 and basic 9 buckle-type seamless combination, just realize being relatively fixed of active carbon filter net 6, sea handkerchief filter screen 7, fan and energy module 8 and shell body 5.

Shell body 5 has vent (fan shape through hole), for by extraneous gas inhalation mask.

Basis 9 and mask main body 1 are removable seamless combination structure, in order to conveniently realize the combination between mask main body 1 and filtration and the active air inlet assembly 2 of different outfits; Resilient membrane 10 has the hole can matched with basis 9, mask main body 1 is fixed in filtration and active air inlet assembly 2

The structure of mask main body 1 is with further reference to Fig. 3, mainly include resilient membrane 10, one-way exhaust layer 11 and interchangeable liner 13 that through-thickness sets gradually from outside to inside, being respectively provided on two sides with soft sealing ring 12 up and down in mask body 1, sealing ring 12 is fixed between one-way exhaust layer 11 and liner 13 in strip slot; Wherein:

Resilient membrane 10 has and fixing wears support shape, can be customized according to consumer demand, can deform within the specific limits (as reasonably folded) during by External Force Acting, and external force can revert to after removing and wear support shape.

The inside of one-way exhaust layer 11 comprises multiple little unidirectional valve opening, can make air by mouth and nose laterally extraneous exhale time unimpeded, otherwise, extraneous surrounding air can not can not reverse flow entrance nasal side.

Sealing ring 12 is the sealing ring of the soft materials such as latex or the foam of being located at one-way exhaust layer 11 inside edge, in the process wearing mask, compressive deformation due to soft material, gap between mask and face is preferably minimized, and owing to its material is sufficiently soft, is therefore not compromised by pressurized and causes that the face of wearer does not feel well.

Liner 13 is the material (as selected the filter paper of filtration parameter according to the actual requirements) that a layer absorbent is stronger, without obvious hole (hole diameter is micron order), for absorbing the steam of exhalation, ensure the dry of mask main body 1, liner 13 folded-edge covers in the inside of mask main body 1, after mask repeatedly uses 5��10 times, can will replace.

By filtration and active air inlet assembly 2, the mask of the present invention ensures that wearer is drawn onto fresh air, the expiration of wearer is ensured by one-way exhaust layer 11, and by the repeatable utilization rate that the multiple structure of mask main body 1 is improved mask and the comfortableness wearing in process.

Above in association with accompanying drawing, embodiments of the invention having been explained, accompanying drawing herein is used to provide a further understanding of the present invention. Obviously; the foregoing is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any be to one skilled in the art can readily occur in, essentially without departing from the change of the present invention or replacement, be also all contained within protection scope of the present invention.
