Detailed description of the invention
Fig. 1 is the figure for indicating the structure of disposable dust protective mask of the embodiment of the present invention.It (a) is from back-surface side
The perspective view of mask, (b) be a pair of of filter before forming bowl-shape filtration members main view, (c) be face's contact cloth ring
The main view of shape pieces of cloth, (d) be conformal part perspective view.(e), (f) is the variation of the cyclic annular pieces of cloth of face's contact cloth
Main view.
Specific embodiment
The disposable dust protective mask of the embodiment of the present invention is illustrated.
As shown in Fig. 1 (a), disposable dust protective mask 1 has mask main body 5 and is installed on the fastening straps 6 of mask main body 5,
There are aforementioned mask main body 5 bowl-shape filtration members 2, conformal part 3, face to contact cloth 4, and aforementioned conformal part 3 is from forming bowl-shape filtration members 2
Concavity curved surface back-surface side relative in bowl-shape filtration members 2 be fitted into, keep filtration members 2 it is bowl-shape, aforementioned conformal part 3 is bone
Framework is made, and has an aeration, aforementioned conformal part 3 be it is bowl-shape, aforementioned face contact cloth 4 from the peripheral part of bowl-shape filtration members 2 to
Radially inner side extends.
The mask main body 5 of anti-dust mask 1 is manufactured according to sequence below.As shown in Fig. 1 (b), by symmetrical two
Filter 2a, 2a overlapping are opened, in central portion 2a', 2a' weld and joint, forms bowl-shape filtration members 2.Such as single dotted broken line in Fig. 1 (c)
Shown, cutting is laminated with having for the soft resin piece of polyurethane etc. in the single side of nylon fiber or polyester fiber quality and stretches
Property and with non-ventilating property quality, form the pieces of cloth 4a of arcuation1, the pieces of cloth 4a of aforementioned arcuation1With with towards radial outside by
Two end edge 4a of the mode oblique in the direction of extension of flaring exhibition1', by the pieces of cloth 4a of arcuation1Two end edge 4a1' each other deposition connect
It closes, as shown in solid in Fig. 1 (c), the cyclic annular pieces of cloth 4a of formation.At cyclic annular pieces of cloth 4a, joint portion 4b is with it nearby partially to face
Outside direction is prominent.As shown in Fig. 1 (a), make joint portion 4b opposed relative to the bridge of the nose abutting part 2b of bowl-shape filtration members 2, it will be cyclic annular
The peripheral part weld and joint of the outer peripheral edge portion of pieces of cloth 4a and bowl-shape filtration members 2 forms face and contacts cloth 4.Then, by bowl-shape filtering
Part 2 and face's contact cloth 4 turn in the component of one, make the bowl-shape conformal of the aeration of skeleton construction shown in Fig. 1 (d)
The central opening that part 3 passes through face's contact cloth 4 to be fitted into from the back-surface side of bowl-shape filtration members 2 relative in bowl-shape filtration members 2,
It is connected to the rear surface of bowl-shape filtration members 2, as shown in Fig. 1 (a), keeps the bowl-shape of filtration members 2.
At anti-dust mask 1, face's contact cloth 4 is using near the joint portion 4b of the specified location as extending direction and its
Part is preformed with retractility and with the cyclic annular pieces of cloth 4a of non-ventilating property to face outside direction mode outstanding, so wearing
When wearing masks, mask is partially followed near face outside direction position outstanding, that is, joint portion 4b of face's contact cloth 4 and its and is worn
The shape of the bridge of the nose of wearer does not generate gap between bridge of the nose side and face's contact cloth.
As shown in Fig. 1 (e), it is also possible to form the pieces of cloth 4a of a pair of of arcuation2, the pieces of cloth 4a of aforementioned a pair of arcuation2Have
The end edge 4a of a side orthogonal with extending direction2' the mode that gradually extends of He Yixiang radial outside is another with extending direction oblique
The end edge 4a of one side2' ', by the end edge 4a orthogonal with extending direction2' each other and the end edge 4a with extending direction oblique2' ' each other
Weld and joint respectively forms cyclic annular pieces of cloth 4a, alternatively, can also form extending direction central portion to radial direction as shown in Fig. 1 (f)
Interior lateral bend and two end edge 4a of extending direction3' the arcuation orthogonal with extending direction pieces of cloth 4a3, by two end edge 4a3' deposition each other
Engagement forms cyclic annular pieces of cloth 4a.
Also it can replace the end edge weld and joint of cyclic annular pieces of cloth, push ring plain body to make the set portion of extending direction
Divide prominent to face outside direction.
Conformal part 3 can be the skeleton construction body as above-described embodiment, can be mesh configuration body, be also possible to more
Hole sheet structure.As long as being able to maintain that bowl-shape rigidity with aeration and when there is wearing anti-dust mask.
Industrial availability
The present invention can be used in the disposable dust protective mask for having conformal part extensively.
