Abstract
The utility model provides an antifog haze face guard, includes transparent face guard and settles the protectiveness helmet on it, is connecting gas permeability lower jaw area between the protectiveness helmet and the transparent face guard, is installing the hat lining apical string below the protectiveness helmet, is installing between hat lining apical string forward position and the transparent face guard and is crossing the filter core frame, cross and is placing the disposable filter core of crossing above the filter core frame, lithium cell board drive fan motor through the air honeycomb duct through disposable cross after the filter core filters blow air -purifying into transparent face guard in the breathing of confession user. Antifog haze face guard provide an effective protection for the user.
Description
(1) technical field
This utility model relates to the haze face shield that a kind of individual uses。
(2) background technology
In the face of haze weather, it is poor that people commonly use common cotton cloth respirator protected effect, uses the mask with filtration core, breathing to have some setbacks, especially in summer, wears masks sultry, and comfort is poor。In winter, owing to the steam breathed flows out from mask edge, frequently result in the glasses minute surface atomization worn and affect sight line。It addition, clean environment work, construction and decoration workman, and the people of various dust atmosphere operation, present stage can provide the namely common cotton cloth respirator of protection or the mask with filtration core, degree of protection or comfort all relatively low。
(3) summary of the invention
In order to overcome and solve existing common cotton cloth respirator and the mask degree of protection with filtration core or the relatively low deficiency of comfort, this utility model provides the haze face shield that a kind of degree of protection is high and comfort is strong。
This utility model solves its technical problem and be the technical scheme is that
A kind of haze face shield, including transparent face mask, described transparent face mask placed over protective headgear, breathability chin strap it is connected between described transparent face mask and described protective headgear, steam vent is had below described breathability chin strap, described protective headgear installed below hat lining heading tape, between described hat lining heading tape forward position and described transparent face mask, filtration core framework is installed, it is airtight that described filtration core frame edge and described hat lining heading tape side and described protective headgear periphery packing cloth cover lid, described filtration core framework is placed above disposable filtering core, described disposable filtering core is provided above airflow duct, described airflow duct is connected with described protective headgear, described airflow duct afterbody is installed with fan electromotor, described fan electromotor side is installed with lithium-cell plate, described lithium-cell plate side is installed with switch, it is connected to back ferrule after described hat lining heading tape。
Hat lining heading tape is placed in overhead by user by this utility model in use, leave behind transparent face mask, breathability chin strap is buckled in chin, adjust back ferrule tightness, guarantee haze face shield correct be worn over head, then switch is pressed, now fan electromotor is powered by lithium-cell plate, fan electromotor blows into transparent face mask inwall after the filtration of disposable filtering core being placed above by airflow duct via filtration core framework after being sucked by extraneous air, owing to the face of transparent face mask and sealing sheet and breathability chin strap and wearer defines the closing cavity of, because being that normal pressure is supplied gas, the gas blown under gas pressure flows through a part of clean air and breathes for user, the waste gas of air unnecessary after filtration and user exhalation, discharged by breathability chin strap steam vent。
The beneficial effects of the utility model are in that: 1. using disposable filtering core to filter, degree of purification is high。2. disposable filtering core is changed easily。3. using fan electromotor supply, autonomous respiration is very unobstructed。4. the waste gas of exhalation can be discharged by the mode of supplying gas of normal pressure in time, because gaseous exchange does not have dampness to remain in a standstill in such transparent face mask, will not produce atomization affects sight line, and the people worn glasses eliminate lens atomization puzzlement especially。5. haze in winter face shield has Windproof thermal insulation function, is particularly suitable for cycling and outdoor study crowd。6. summer is because supply air system can discharge heat and face body surface steam in time, and transparent face mask can reach function sun-proof, anti-ultraviolet, has preventing heatstroke effect。

Fig. 1 is sectional view of the present utility model
Fig. 2 is exploded view of the present utility model
(5) detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further described。
Embodiment one
Shown in 2, a kind of haze face shield, including transparent face mask 1, described transparent face mask 1 placed over protective headgear 2, it is connected to breathability chin strap 3 between described transparent face mask 1 and described protective headgear 2, described protective headgear 2 installed below hat lining heading tape 4, between described hat lining heading tape 4 forward position and described transparent face mask 1, filtration core framework 5 is installed, described filtration core framework 5 edge and described hat lining heading tape 4 side and described protective headgear 2 periphery seal sheet 6 and cover sealing, steam vent 7 is had below described breathability chin strap 3, described filtration core framework 5 is placed above disposable filtering core 8, described disposable filtering core 8 is provided above airflow duct 9, described airflow duct 9 is connected with described protective headgear 2, described airflow duct 9 afterbody is installed with fan electromotor 10, described fan electromotor 10 side is installed with lithium-cell plate 11, described lithium-cell plate 11 side is installed with switch 12, described hat lining heading tape 4 is connected to back ferrule 13 below。
By user, hat lining heading tape 4 is placed in overhead during use, leave behind transparent face mask 1, breathability chin strap 3 is buckled in chin, adjust back ferrule 13 tightness, guarantee haze face shield correct be worn over head, then switch 12 is pressed, now fan electromotor 10 is powered by lithium-cell plate 11, fan electromotor 10 is placed above after disposable filtering core 8 filters via filtration core framework 5 is blown into transparent face mask 1 inwall by airflow duct 9 after being sucked by extraneous air, owing to the face of transparent face mask 1 and sealing sheet 6 and breathability chin strap 3 and wearer defines the closing cavity of, because being that normal pressure is supplied gas, the gas blown under gas pressure flows through a part of clean air and breathes for user, the waste gas of air unnecessary after filtration and user exhalation, discharged by the steam vent 7 of breathability chin strap 3。
