Description
Technical field
the utility model relates to a kind of mouth mask.
Background technology
mouth mask has certain filtration to entering the air of lung, in the time that respiratory infectious disease is popular, in the environment polluting, when operation, wears masks and has extraordinary effect at dust etc.But in use there is following defect in existing mouth mask:
1, because face shield is directly coated on cheek, respiratory resistance is larger, and wearer can feel unsmooth breath and the inconvenience of speaking;
the waste gas of 2, breathing out is gathered in mouth mask inner side, and easily producing waste gas can suction phenomenon.
Summary of the invention
the utility model object is: provide a kind of with breathing the mouth mask of switch, the support ring in its face shield makes to be separated with spacing between face shield and wearer's nose, can make wearer's breathing smooth and easy, can not feel to feel oppressed; In addition, switch baffle plate can or suck gas at wearer's breath, automatically opens or closure, in facilitating wearer to exhale and speaking, also avoids ambient atmos directly by switch contacts inhaling face shield inside.
the technical solution of the utility model is: a kind of mouth mask with breathing switch, comprise face shield and be arranged on the ear band of face shield both sides, the corresponding wearer's mouth and nose of described face shield position is provided with the support ring of hollow out, face shield front side offers installing port and this installing port place and is provided with the switch contacts of opening and support ring internal communication, described switch contacts is connected with switch baffle plate that can closed above-mentioned switch contacts opening rotationally, and the opening madial wall of switch contacts is provided with the block coordinating with switch baffle plate.
the concrete mounting means of described switch baffle plate and the arrangement of corresponding block thereof are: being rotationally connected between switch baffle plate and switch contacts realized by bearing pin and switch contacts pin joint in the middle and upper part of described switch baffle plate, and described block comprises the upper block that is positioned at switch baffle plate outside and the lower block that is positioned at switch baffle plate inner side.The setting of above-mentioned block, can avoid switch baffle plate automatically to open when large because of cover exogenous wind, avoids ambient atmos directly by switch contacts inhaling face shield inside.
in order to expand the circulation of air in air volume in face shield, raising face shield, the preferred described support ring of the utility model is netted support ring.For mouth mask is better coordinated with wearer's nose, described support ring top is provided with the support slot setting up for nose.Described face shield is provided with corresponding with wearer's bridge of the nose, deformable support chip in the position of support ring top.
when this mouth mask is worn, above-mentioned support chip is pinched to compressive strain makes it coordinate with wearer's the bridge of the nose, the support slot of support ring is coordinated with wearer's nose simultaneously, support ring is erected on nose, now support ring makes to be separated with spacing between face shield and wearer's nose, can make wearer's breathing smooth and easy, can not feel to feel oppressed.And wearer is exhaling and while speaking, switch baffle plate is opened because of the face shield internal gas pressure automatic turning that raises, make like this wearer exhale smooth and easy, speak easily; When air-breathing, switch baffle plate is because the face shield internal gas pressure reduction while is under own wt effect, and auto back is transferred the opening of closing switch joint, avoids ambient atmos directly by switch contacts inhaling face shield inside.
the utility model has the advantages that:
1, in the utility model, the support ring in face shield makes to be separated with spacing between face shield and wearer's nose, can make wearer's breathing smooth and easy, can not feel to feel oppressed.
, the utility model exhales and while speaking wearer, switch baffle plate is opened because of the face shield internal gas pressure automatic turning that raises, make like this wearer exhale smooth and easy, speak easily; When air-breathing, switch baffle plate is because the face shield internal gas pressure reduction while is under own wt effect, and auto back is transferred the opening of closing switch joint, avoids ambient atmos directly by switch contacts inhaling face shield inside.
, support ring is engraved structure in the utility model, has improved the circulation of air in face shield.

Detailed description of the invention
embodiment: as shown in Figures 1 to 4, a kind of mouth mask with breathing switch, comprise face shield 1 and be arranged on the ear band 2 of face shield 1 both sides, the corresponding wearer's mouth and nose of described face shield 1 position is provided with the support ring 3 of hollow out, face shield 1 front side offers installing port 4 and this installing port 4 places and is provided with the switch contacts 6 of opening 5 and support ring 3 internal communication, the outside portion of described switch contacts 6 is connected with switch baffle plate 7 that can closed above-mentioned switch contacts 6 openings 5 rotationally, and the opening madial wall of switch contacts 6 is provided with the block 8 coordinating with switch baffle plate 7 in the inner side of switch baffle plate 7.In the present embodiment, being rotationally connected between switch baffle plate 7 and switch contacts 6 realized by bearing pin 11 and switch contacts 6 pin joints in the middle and upper part of described switch baffle plate 7, and described block 8 comprises the upper block 12 that is positioned at switch baffle plate 7 outsides and the lower block 13 that is positioned at switch baffle plate 7 inner sides.The setting of above-mentioned block 8, can avoid switch baffle plate 7 automatically to open when large because of cover exogenous wind, avoids ambient atmos directly by switch contacts 6 inhaling face shield 1 inside.
in order to expand the circulation of the interior air volume of face shield 1, raising face shield 1 interior air, the preferred described support ring 3 of the utility model is netted support ring.For mouth mask is better coordinated with wearer's nose, described support ring 3 tops are provided with the support slot 9 setting up for nose.Described face shield 1 is provided with corresponding with wearer's bridge of the nose, deformable support chip 10 in the position of support ring 3 tops.
when this mouth mask is worn, above-mentioned support chip 10 is pinched to compressive strain makes it coordinate with wearer's the bridge of the nose, the support slot of support ring 39 is coordinated with wearer's nose simultaneously, support ring 3 is erected on nose, now support ring 3 makes to be separated with spacing between face shield 1 and wearer's nose, can make wearer's breathing smooth and easy, can not feel to feel oppressed.And wearer is exhaling and while speaking, switch baffle plate 7 is opened because of the face shield 1 internal gas pressure automatic turning that raises, make like this wearer exhale smooth and easy, speak easily; When air-breathing, switch baffle plate 7 is because the 1 internal gas pressure reduction while of face shield is under own wt effect, and auto back is transferred the opening 5 of closing switch joint 6, avoids ambient atmos directly by switch contacts 6 inhaling face shield 1 inside.
below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the utility model scope required for protection.
