Description
Technical field
The utility model relates to a kind of articles for labour protection, especially relates to a kind of glass of type anti-dust respirator.
Background technology
Industrial face mask generally is made into a glass type; Advantage such as cup type anti-dust respirator has high efficiency filter, anti-low toxicity, eliminates the unusual smell, comfortable ventilating and extensively apply to grind fields such as pharmacy industry, agriculture and garden, forestry animal husbandry, food processing industry; Like Fig. 1, shown in Figure 2; The expiration air valve 1 of common cup type anti-dust respirator can guarantee distributing of heat, makes that breathing is lighter; Adjustable nose clamping structure 4 can guarantee that the seal of mouth mask and face is better; Prevent that dust from getting into mouth and nose; The effect one of the sponge strip of bridge of the nose location means is to be the sealing between the increase mouth mask and the bridge of the nose in the general cup type anti-dust respirator, two pressure for the outer pince-nez bar of buffering mouth mask, and it is shaped as strip band gelatin sponge; Size is generally 100 * 10 * 5mm, and material is a soft polyurethane ester foaming material.As shown in Figure 3, the cup 3 of general cup type anti-dust respirator is divided into skin 31, filter course 32, internal layer 33.Its drawback is: one, and the cup type anti-dust respirator of band scalable nose clip is worn for a long time and is made nose produce the sensation that acid is expanded easily, brings extremely uncomfortable sensation for people's use; Two, the area of sponge strip is less, and the dust filter effect is relatively poor; Three, soft polyurethane ester foaming material and human body skin affinity are poor; Four, to paste firmness not strong for sponge strip, and paste sponge strip and increased operation, and production efficiency is lower; Five, mouth mask adopts the raw material of various material, and the quality control difficulty is big.
The utility model content
The purpose of the utility model is exactly in order to address the above problem, and a kind of wearing more comfortable, dust filter efficiency height, good permeability, production efficiency height, cup type anti-dust respirator that the mouth mask entire firmness is strong are provided.
To achieve these goals, the utility model adopts following technical scheme:
A kind of glass of type anti-dust respirator; Comprise an outlet valve of being located at glass type anti-dust respirator bottom, be located at glass band device at type anti-dust respirator edge, be located at the scalable nose clip on glass type mouth mask; The outer PP nonwoven that adopts of said cup type anti-dust respirator, the filter course of said cup type anti-dust respirator adopts fusion spray cloth, and the internal layer of said cup type anti-dust respirator adopts acupuncture cotton; Additionally, at said cup type anti-dust respirator internal layer and mouth and nose contact site one deck strip bridge of the nose bar is set.
The flat shape of said strip bridge of the nose bar is the common arc-plane that constitutes in the first arc limit and the second arc limit.
The said first arc limit overlaps with cup type anti-dust respirator circular edge opening part any 2 circular arcs that constituted, and the said second arc limit is to be the symmetrically arranged circular arc of the axis of symmetry with two the end points lines in the first arc limit.
Two end points wire lengths on the said first arc limit are less than the diameter of cup type anti-dust respirator circular edge opening and greater than 2/3rds of cup type anti-dust respirator circular edge opening.
Said strip bridge of the nose strip adoption polypropylene needle punched non-woven fabrics.
Said strip bridge of the nose strip adoption ultrasonic is welded on the anti-dust respirator body.。
The beneficial effect of the utility model is: the upper end complete closed of (1) bridge of the nose bar and mouth mask, and the area of bridge of the nose bar is big than sponge strip, has improved mouth mask and facial close and degree, and the filter efficiency of dust increases; (2) the cotton affinity with human body skin of acupuncture is higher, and gas permeability is better, wears comfort level and increases; (3) reduce the operation of pasting sponge strip, improved production efficiency; (4) adopt welding procedure, the technology that its firm degree is also pasted is high, and the mouth mask overall quality increases; (5) raw material of the cotton bridge of the nose bar of acupuncture are identical with the inner layer material of mouth mask body, simplified material quality control, help the lifting of quality stability;

The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; A kind of glass of type anti-dust respirator; Comprise an outlet valve 1 of being located at glass type anti-dust respirator bottom, be located at glass band device 2 at type anti-dust respirator edge, be located at the scalable nose clip 4 on glass type mouth mask; The cup 3 of said mouth mask is divided into skin 31, filter course 32, internal layer 33, strip bridge of the nose bar 34, and said cup type anti-dust respirator outer 31 adopts the PP nonwoven, the filter course 32 employing fusion spray cloths of said cup type anti-dust respirator; The internal layer 33 of said cup type anti-dust respirator adopts acupuncture cotton; Additionally, with the mouth and nose contact site one deck strip bridge of the nose bar 34 is set at said cup type anti-dust respirator internal layer 33, said strip bridge of the nose bar 34 adopts the polypropylene needle punched non-woven fabrics.
As shown in Figure 4, the flat shape of said strip bridge of the nose bar 34 is the first arc limit 340 and the second arc limit, the 341 common arc-planes that constitute.The said first arc limit 340 and cup type anti-dust respirator circular edge opening part 2 A overlap with the some circular arc that B constituted, and the said second arc limit 341 is for being the symmetrically arranged circular arc of the axis of symmetry with two terminal A in the first arc limit with putting the B line.Longitudinal center's axis symmetry when wherein, some A wears with mouth mask with some B.Two terminal A on the said first arc limit 340 and some B wire length are less than the diameter of cup type anti-dust respirator circular edge opening and greater than 2/3rds of cup type anti-dust respirator circular edge opening; The length of present embodiment cathetus AB is 90% of mouth mask rim of a cup round diameter; The area of strip bridge of the nose bar satisfies the nose areas that covers face and gets final product, and also can be provided with not according to the scheme of present embodiment.。
Said strip bridge of the nose strip adoption ultrasonic is welded on the anti-dust respirator body; Wherein 2 A in first arc limit 340 of strip bridge of the nose bar and cup type anti-dust respirator circular edge opening part overlap layout with the some circular arc that B constituted, and second arc, 341 limits of strip bridge of the nose bar are arranged on the cambered surface of mouth mask internal layer.
The planar development shape of the strip bridge of the nose bar 34 of cup type anti-dust respirator is as shown in Figure 5, and this strip bridge of the nose bar 34 welds through ultrasonic with the internal layer 33 of cup 3.
The above is merely the preferred implementation of the utility model, and the protection domain of the utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to the protection domain of the utility model.For a person skilled in the art, some improvement of under the prerequisite of the principle that does not break away from the utility model, carrying out, these improve the protection domain that also should be regarded as the utility model.
