Description
[technical field]
The present invention relates to a kind of face shield, particularly relate to a kind of adjustable respiratory mask.
[background technology]
As shown in Figure 1, a kind of breathing mask 1 in the past has a nose cup portion 101, an air admission hole 102 that is formed at this nose cup portion 101 and can be communicated with an air supply pipe 2, and one from the extended up support bar 103 of these nose cup portion 101 one.
Whereby; When the user utilizes two headbands 3 that are connected with these support bar 103 tops, this nose cup portion 101 respectively; This breathing mask was hung on a last time in 1 year, and this nose cup portion 101 can cover and be overlying on around user's nose, and; The top of this support bar 103 then can be resisted against user's forehead, urges in the pressure at nasion place to disperse this nose cup portion 101.
Yet; Because this support bar 103 is to extend from these nose cup portion 101 one, this support bar 103 also can't be with respect to this nose cup portion its angle that tilts towards user's forehead of 101 adjustment, therefore; For the user of different face contours; It also can't make the adjustment of the most comfortable according to the deep degree of individual profile, so, often still can cause the sense of discomfort that urges at user's nasion place.
[summary of the invention]
The objective of the invention is is providing a kind of adjustable respiratory mask that can make the adjustment of the most comfortable according to user's face contour.
Adjustable respiratory mask of the present invention comprises: a body, a support member, and a worm screw part.This body has a basic shell; And soft case that is connected with this base shell; This base shell cooperates with this soft case and defines an accommodation space; This base shell has that an end wall, one side are extended from this end wall periphery towards this soft case and the perisporium that is connected with this soft case, two pivot ears that are arranged at intervals on this end wall, reaches an air admission hole that is communicated with this accommodation space, and this end wall has a depressed part that is adjacent to said pivot ear; This depressed part defines an installing space that separates with this accommodation space, and this soft case has one and covers opening in contrast to this air admission hole and the cover that is communicated with this accommodation space.This support member has one and axially is rotatably installed on the pivot joint end of this base shell, the butt end in contrast to this pivot joint end around one first; And a plurality ofly being arranged at the worm-gear toothing of this pivot joint end around this first axially spaced-apart, this pivot joint end is to be installed between said pivot ear and to extend in this installing space.This worm screw part is around one second installing space that axially is rotatably installed on this base shell, and this worm screw part and the engagement of said worm-gear toothing when this worm screw part during around this second axial rotation, are ordered about this support member around this first axial wobble.
Beneficial effect of the present invention is: the angle that supplies the user to tilt towards its forehead according to self face contour adjustment support member, and make the adjustment of the most comfortable, effectively to alleviate the sense of discomfort that urges at its nasion place.
