Description

Dust mask

Technical field

The present invention relates to a kind of dust masks, more particularly to one kind user in industry spot operation conveniently to have Imitate the dust mask used.

Background technique

In general, the harmful substances such as many dust, dust, smog, therefore operation are distributed in the air of industry spot Personnel use the hermetic type dust mask that can be covered nose and mouth periphery.This dust mask is divided into two kinds, and one is only Filter need to be replaced from the body of face can be semi-permanently used；Another kind is simply to constitute filter by face body itself, is used It is discarded after one or many.In particular, latter is in the industry cycle referred to as " face-filtering type " dust mask, it is introduced below All dust masks belong to this type.

In addition, the nose of user belongs to the form for sharply protruding warp architecture from organization of human body, everyone Size and form it is slightly different.Therefore, the dust mask of regularization production can not be close to the nose areas of user, hold very much It is also easy to produce space.In this case, harmful substance will be directly entered respiratory apparatus by the space.This is solved to ask Topic, has 2 kinds of schemes available.

A kind of scheme is to adhere to so-called " bridge of the nose compression tool " on dust mask.For example, showing that South Korea infuses in Fig. 1 The dust mask that volume utility model bulletin the 0179830th proposes, this dust mask 1 includes: common hemispherical filter sheet Body 2；For wearing the headband 3 of the filter body 2.Iron plate is attached on the upside of the outer surface of the filter body 2 4, it can be such that the filter body 2 is close to user's bridge of the nose part as bridge of the nose compression tool.

Herein, press with finger can bending according to oneself nose size and form to the iron plate 4 by user State is adjusted, so as to make filter body 2 be close to the bridge of the nose part of user.But such dust-proof surface Cover 1 has the following problems: 1. being formed in appearance and structure for iron plate 4 is not sufficiently stable；2. being attached to the iron on filter body 2 Piece 4 will cause area filtering function loss；3. filter body 2 directly contacts the breathing of user, contain quickly Aquation, to reduce filter efficiency.

So-called " orthoses " is exactly arranged in another scheme on dust mask.For example, showing Japanese Laid-Open in Fig. 2 The dust mask of patent gazette the 2003-320041st proposition, this dust mask 5 is by substantially hemispherical filter sheet It is inserted into grid or mesh form orthoses 7 with plastic resin forms inside body 6 and constitutes, in the upside shape of the orthoses 7 At the protruding type bending section 8 with the shape that can be contacted with the bridge of the nose of user.

Herein, the orthoses 7 is described while the circular shape to filter body 6 is supported and maintains Bending section 8 is also corresponding with user's nasal portion, to help somewhat to be close to filter body 6 to use Person's bridge of the nose part.But such dust mask 5 has the following problems: 4. corresponding to orthoses 7 and filter body 6 Contact area generate sizable filtering function in terms of loss；5. the bending section 8 can not neatly cope with size and The nose to come in every shape, the close property that thus will lead to it with bridge of the nose part reduce；6. filter body 6 directly contacts user Breathing, quickly occur contain aquation, sharply decline so as to cause filter efficiency and respiratory resistance steeply rise.

Just because of there are these problems, therefore the dust mask 1,5 of first and second above-mentioned seed type is in actual work Industry scene is hardly used.

Specific embodiment

About the feature and effect of the present invention " dust mask " that is mentioned above or not yet mentioning, by referring to attached The explanation that figure carries out the embodiment of the present invention will be clearer.In the attached drawing after Fig. 3, dust mask according to the present invention It is indicated with symbol 10.

Referring to Fig. 3 and Fig. 5, it is solid type that dust mask 10 of the invention, which includes: filter body 11, and package makes The nose of user and mouth periphery；Veneer portion 12, for annular and its outer periphery and the edge termination of the filter body 11 connect It closes；Orthoses 13 is solid type, according to can handling mode be set to inside the filter body 11, and orthoses 13 Edge termination be inserted into the bonding part 15 of the filter body 11 with veneer portion 12.The two sides of the filter body 11 connect It is connected to headband 14, the dust mask 10 can be fixed on the appropriate location of user's face.

Although the basic structure of this dust mask belongs to Japanese Laid-Open Patent Publication the 2003-320041st proposition and sheet The known features shown in specification by Fig. 2, but dust mask 10 of the invention is in the specific composition of aftermentioned orthoses 13 On have its technical characteristic.

The filter body 11 can be using any well known to capable of filtering out dust in air or dust etc. Mask filtering material.For example, can be using the structure that of the same race or xenogenesis filter layer is carried out to multiple-layer stacked.In addition, the mistake Filter body 11 is substantially hemispherical using the form for suitably forming face space.But since filtering material is with flexible Property, it is easy to destroy its form the pressure of very little or loading.Therefore, it is provided with the orthoses 13 for keeping form.

The veneer portion 12 be by soft resins such as polyurethane by lamination (laminate) processing in nylon fiber or The sheeting that the one side of the fabrics such as the synthetic fabrics such as polyester fiber or cotton goods is formed.The material in the veneer portion 12 The rubber materials such as rubber, silica gel, urethane can be used.But if it is considered that the facial factors such as sense of touch or flexibility, generally Think the sheeting than advantageous.Furthermore, it is contemplated that the form of the bridge of the nose, is fabricated to specially-shaped annular for the veneer portion 12, So as to neatly cope with the different shape of each user, there is good close property.

For the filter body 11 is with veneer portion 12, the edge termination of the filter body 11 and veneer portion 12 outer periphery, which is engaged with each other, to be integrally formed.About the method for engagement, the methods of adhesive, sewing, welding can be used.Separately Outside, the orthoses 13 is set to the filter body 11 by the method that its edge termination is inserted into the bonding part 15 Inside.In the present invention, the orthoses 13 include: the solid shape whole to filter body 11 and dust mask 10 into The supporter 16 of row support；Adhere to and be fixed on the bridge of the nose compression tool 18 of 16 outer upper end of supporter.

Specifically, the supporter 16 is harder than the filter body 11 by material and has loose gas permeability tissue The hydroscopicity nonwoven fabric material of structure is constituted, and the supporter 16 is formed as solid type, and the supporter 16 is arranged to its outside With the inner faces contact of the filter body 11, the solid shape whole to filter body 11 and dust mask 10 is propped up Support.

In general, so-called " non-woven fabrics " is exactly without weaving processes such as braiding and tattings, by fibers parallel or not It aligns, is allowed to combine using resin binder or by heating connection, is made into felt or lamellar form.Fiber can be with Use a variety of chemical fibres such as terylene, polypropylene fibre, artificial silk, vinyon, nylon.This non-woven fabrics with used raw material type, The thickness of fiber, generation and different physical property is shown in conjunction with method, type of adhesive etc., therefore can be according to its use Purpose and purposes select or make needed for non-woven fabrics.

In the present invention, the supporter 16 is while the form to filter body 11 is supported, and is also used to pair User breathes the moisture generated and absorbs.It is therefore desirable to have so-called " rigidity " and " water imbibition ".But the support Body 16 does not have the function of filter.Thus, for example, compared with filter body 11, even if its tool of so-called non-woven fabrics There are fine and close institutional framework or surface density structure, this gas permeability that will lead to dust mask reduces, and thus increases exhaling for user Suction drag, and this is the factor for having to consider.As a result, in the present invention, the supporter 16 is defined as: " by material ratio The harder and hydroscopicity nonwoven fabric material with loose gas permeability institutional framework of the filter body 11 is constituted ", outside With the interior side contacts of the filter body 11.

Preferably, the supporter 16 includes the V-shaped groove 17 formed in its edge upper end.The V-shaped groove 17 and user The bridge of the nose it is corresponding, so as to be close to the filter body 11 with the bridge of the nose perfection of user.For example, shown in Fig. 1 and Fig. 2 Existing dust mask 1,5 in, be correspondingly formed protruding type bending section 8 with user's bridge of the nose.In this case, the bending Portion 8 excessively covers nose, thus can make troubles to user, and can interfere to breathe.On the contrary, the V-shaped groove in the present embodiment Even if 17 are close to the bridge of the nose of user, the bridge of the nose will not be allowed inconvenient, still be able to freely breathe.

The compression tool 18 is made of the material that the curvature that formed according to user's contour of nasal bridge can be adjusted, horizontal To the outside upper end for being attached to the supporter 16, compression tool 18 is covered by the filter body 11, prevents from squeezing work Tool 18 exposes to outside.That is, the compression tool 18 by can be carried out according to user's bridge of the nose size and form bending adjusting material Material is constituted, and in the state of being attached on supporter 16, is covered compression tool 18 by filter body 11.Preferably, institute Stating compression tool 18 is relatively thin rectangle sheet metal or is inserted into the answer print that transverse metal core is formed into flexible material, can It is attached on the supporter 16 with the methods of being melted by sewing, adhesive, ultrasonic wave, heat.

In the present embodiment, the compression tool 18 is from the main body 19 of flexible rubber or plastics and respectively to its upper and lower sides The answer print that the metal core 20 of insertion is constituted, it have it is lighter than sheet metal, it is easy to attach, it is excellent can freely to carry out bending adjusting etc. Point.Preferably, make the thickness of 19 middle section of main body thinner than 20 part of upper and lower sides metal core, just more held using the middle section Easily compression tool 18 is attached on supporter 16 by a variety of methods.For example, symbol 21 is exactly in the middle section of main body 19 The ultrasonic bonding trace formed.

Symbol 22 is to penetrate through filter body 11 and supporter 16 to facilitate the breathing of 10 user of dust mask The valve of setting, it is the dedicated so-called check valve (check-valve) of exhaust for making air be merely able to flow to a direction. The valve 22 is not necessarily limited to the position, considers from the user's angle for wearing dust mask 10 of the present invention, Ke Yipei It sets in left side, right side or center.Symbol " H " is the hole for installing the valve 22.

Referring to Fig. 6 it is found that dust mask 10 of the invention is matched using the headband 14 that 11 two sides of filter body have It sets in user's face appropriate location.In this case, V-shaped groove 17 and compression tool 18 configuration of 16 upper end of supporter On the bridge of the nose of user.In this state, user presses compression tool 18 equably with finger or so close to the bridge of the nose, Just it is capable of forming bending corresponding with bridge of the nose size, form.The compression tool 18 can be adjusted to that difference is suitble to make as a result, The bending shape of user, and keep the dust mask 10 including supporter 16, veneer portion 12, filter body 11 whole and make It is close to completely user's bridge of the nose part.

User can safely breathe as a result,.In this case, by breathing generate moisture with filter sheet It is most of before the contact of body 11 all to have been absorbed by the supporter 16 of the orthoses 13, the supporter 16 and filter body 11 separation, so as to easily handle moisture very much.Therefore, dust mask 10 of the invention hardly occurs because making The case where user breathes the moisture generated and leads to the damage of dust mask or reduce filter efficiency.

Fig. 7 and Fig. 8 respectively illustrates the method that the supporter 16 is configured to solid type.First method, will substantially The center portion of rounded nonwoven fabric sheet 23, which carries out pressurization by hot pressing, can substantially form hemispherical.Second of side Method will using vertically substantially respectively cutting upside and downside by certain length in the nonwoven fabric sheet 24 of slightly longer ellipse Opposite slice can also form the solid type of center projections along direction superposition (arrow referring to shown in Fig. 8) intersected with each other.

No matter made of cited any method, as long as belonging to condition defined above, i.e., " institute is compared by material The harder and hydroscopicity nonwoven fabric material with loose gas permeability institutional framework of filter body 11 is stated to constitute ", the support Body 16 is in the present invention with regard to value having the same.
