The specific embodiment
Explain with reference to the accompanying drawings the specific embodiment of the present utility model.
Fig. 2 shows according to the front schematic view of the respiratory protection cover of a kind of embodiment of the present utility model.In Fig. 2, Reference numeral 20 represents respiratory protection cover, and 21 represent the main body of respiratory protection cover, and 22 represent the blade of respiratory protection cover, and 23 represent the air-vent of respiratory protection cover, and 24 represent the flanging of respiratory protection cover.
As can be seen from Figure 2, the shape of the main body 21 of the respiratory protection cover 20 of illustrated embodiment is water-drop-shaped substantially from this illustrated seeing above.Should understand, in optional embodiment, this main body 21 also can be arranged to other shape, and be preferably and become a ring-type (ring-type herein must not be circular), still, the shape of this main body 21 must be suitable for and be arranged on inhales between the filter cotton and locking cover of exhaling device.Specifically ask for an interview the hereinafter specific descriptions about Fig. 4.Be formed with multiple blades 22 at the mid portion of main body 21, multiple blades 22 are the form of the blade on shutter and arrange.Below each blade 22, be provided with one or more air-vents 23.Arranging of these blades prevents that by being conducive to water droplet from touching the filter cotton of respirator, and the setting of these air-vents 23 makes it possible to air and circulates unobstructedly.Be formed with a circle flanging 24 at the outer rim place of main body 21, when this respiratory protection cover 20 is to lock cover to be locked on the mask body of respirator and filter cotton by use.
Can understand, the respiratory protection cover 20 of illustrated embodiment has been arranged to the shape of symmetrical water droplet, it is not only beneficial to attractive in appearance, main is can meet human face's nose top to the shape of cheek, forehead, thereby be convenient to and the other parts phase sealed engagement of respirator, make water droplet or current etc. all can not flow in respirator and soak filter cotton at the connecting portion place of the main body of filter, filter cotton, respiratory protection cover and locking cover.In addition, blade 22 and air-vent 23 are in main body 21 pars intermedia offices preferably but must not be arranged symmetrically, being arranged symmetrically with herein can either realize symmetrical succinct outward appearance, also guaranteed that respiratory protection cover left and right weight is consistent, both sides air intake structure is unanimously more suitable for breathing and uses, improved the comfortableness while wearing simultaneously.
Fig. 3 shows according to the schematic side elevation of the respiratory protection cover of aforementioned embodiments of the present utility model.As can be seen from the figure, the arc that the blade 22 of the respiratory protection cover 20 in this embodiment is slightly forward and is bent upwards, thereby and be obliquely installed and shelter from blade 22 air-vent 23 below, in the time that being dropped on blade 22, water droplet etc. by automatically towards the both sides landing of blade 22 or the adjacent blades below blade above is directly slipped to, can not drop in air-vent 23 until leave this respiratory protection cover 20.Although having five blades 22 and being thereunder provided with respectively air-vent 23 shown in figure, but, those skilled in the art can expect, also can use the blade 22 of other quantity and the shape of air-vent can be rounded, square etc. arbitrary shape, do not enumerate at this.
In optional another embodiment, the blade that traverses as shown in FIG. whole respiratory protection cover 20 also can be set, for example, can be arranged to each blade only for sheltering from one or several air-vents, not only can realize different outward appearances with this, can also more effectively realize drainage to dropping in water on respiratory protection cover 20 etc., be convenient to drop and leave sooner respirator.
From Fig. 2 and Fig. 3, clearly show that the flanging 24 of respiratory protection cover 20.The shape of flanging 24 is suitable for being pressed between mask body, filter cotton and locking cover and forms sealing at joint.While exhaling device in conjunction with Fig. 4 and Fig. 5 explanation according to suction of the present utility model hereinafter, will be engaged into this step describes.
Fig. 4 shows according to the schematic perspective view of the respirator of a kind of embodiment of the present utility model.Fig. 5 shows the schematic three-dimensional exploded view according to the respirator of aforementioned embodiments of the present utility model.In Fig. 4 and Fig. 5, Reference numeral 30 represents respirator, 31 presentation surface cover bodies, and 32 represent filter cotton, and 33 represent locking cover, and 34 represent fastening straps, and 35 represent side shackle member, 36 represent end shackle member.
As shown in Figures 4 and 5, mainly comprise mask body 30, filter cotton 32, respiratory protection cover 20, locking cover 33 etc. according to the respirator 30 of present embodiment, mask body 30 and locking cover 33 cover shackle member 36 at the bottom of two side shackle member 35 on 33 and by locking and are connected in the corresponding shackle member of mask body 30 and engage, 20, filter cotton 32 and respiratory protection cover are clamped between mask body 30 and locking cover 33 by edge 24 places, and this joint is watertightness, the water, flowing down from respirator 30 can not be penetrated on filter cotton 32 at this.
Fig. 6 shows according to the respirator of aforementioned embodiments of the present utility model and is worn over the design sketch on head mould.As can be seen from the figure, because the shape of mask body 31 is suitable for the facial profile of fitting, so respirator 30 and face contour can form airtight effect; In preferred situation, the part of the composition surface contouring of the mask body 31 of respirator 30 can adopt flexible material so that strengthen the effect of laminating.Like this, in the time having water droplet to drop on respirator 30, current will flow along cheek, or flow on the side of respirator 30 along mask body 31, or then drip and can not enter into the air-vent that is positioned at blade below of respiratory protection cover 20 along the blades flows of respiratory protection cover 20.Visible, water can not flow to respirator 30 inside, the filter cotton of the respirator 30 of can not getting wet, has overcome foregoing problems common in prior art.
As above with reference to the accompanying drawings the specific embodiment of the present utility model is described in detail.Remodeling or modification that those skilled in the art can be equal to feature concrete in embodiment according to the above description, certainly, the embodiment of these changes also will fall in the protection domain that claims cover.
