呼吸面罩breathing mask

技术领域technical field

本发明涉及一种呼吸面罩，特别是涉及一种用于供应正压空气予使用人的呼吸面罩。The invention relates to a breathing mask, in particular to a breathing mask for supplying positive pressure air to a user.

背景技术Background technique

参阅图1，现有的呼吸面罩11包括一个罩设于一个使用人12的口鼻部的面罩单元111，及一个安装于该面罩单元111并用以支撑该使用人12的额头的前额支撑架112，如此，就能够利用一个安装于该面罩单元111上的通气管13以将正压空气输入该呼吸面罩11内以供该使用人12使用。Referring to Fig. 1, the existingbreathing mask 11 includes amask unit 111 that is arranged on the mouth and nose of auser 12, and aforehead support frame 112 that is installed on themask unit 111 and is used to support the forehead of theuser 12 In this way, aventilation tube 13 installed on themask unit 111 can be used to input positive pressure air into thebreathing mask 11 for use by theuser 12 .

于使用时，利用系带14分别自该前额支撑架112的两侧以及该面罩单元111的两侧分别朝该使用人12的头部后方穿绕，此时，系带14所施加的拉力将使该前额支撑架112及该面罩单元111的两侧分别固定于该使用人12的额部及两颊内侧，此时该面罩单元111的中央部分就能够覆盖于该使用人12的口鼻部并以一个贴靠力贴靠于该使用人12的鼻根处。When in use, thestraps 14 are used to pass around the back of the head of theuser 12 respectively from both sides of theforehead support frame 112 and the both sides of themask unit 111. At this time, the tension applied by thestraps 14 will Make thisforehead support frame 112 and the both sides of thismask unit 111 be respectively fixed on the forehead of thisuser 12 and the inside of both cheeks, now the central part of thismask unit 111 just can cover this user's 12 nose and mouth And lean against the root of the nose of theuser 12 with an abutting force.

然而，由于该贴靠力大小是与该使用人12的额型、两颊外型及鼻型有关，因此以额头及两颊位置之间的直线做为一条基准线L，鼻根处相对该基准线较为凹陷的使用人12于鼻根处所承受的贴靠力较小，会造成该呼吸面罩11覆盖不全而产生正压空气外泄的现象，相反地，鼻根处相对该基准线L较为突出的使用人12于鼻根处所承受的贴靠力则非常的大，于穿戴时会产生不适感而无法久戴，因此，同一种款式的呼吸面罩是无法满足全部不同额型、两颊外型，及鼻型的使用人12使用。However, since the size of the abutting force is related to the forehead shape, cheek shape and nose shape of theuser 12, the straight line between the forehead and the cheeks is used as a reference line L, and the base of the nose is opposite to the nose shape. Theuser 12 with a relatively concave reference line bears less abutting force at the root of the nose, which will cause incomplete coverage of thebreathing mask 11 and cause leakage of positive pressure air. The protrudinguser 12 bears a very large abutment force at the root of the nose, which will cause discomfort when worn and cannot be worn for a long time. Therefore, the same style of breathing mask cannot satisfy all the requirements of different forehead shapes, outer cheeks, etc. Type, andnose type users 12 use.

另外，如美国专利US6532961中揭露与前述的呼吸面罩11相类似的调整式呼吸面罩，其差异的部分在于：该前额支撑架包括一个贴靠于该使用人的额头上的推抵件，及一个安装于该面罩单元与该推抵件之间以调整该推抵件的调整关节部，该推抵件随该调整关节部的调整而改变推抵件相对该面罩单元的角度，而适合于不同额头高度的人所使用。但是，这种方式并没有使呼吸面罩贴靠鼻根的位置改变，仍然无法解决呼吸面罩贴靠鼻根时所产生的问题，所以仍无法满足任何使用人于佩带呼吸面罩时取得最舒适的效果。In addition, as disclosed in U.S. Patent No. 6,532,961, an adjustable breathing mask similar to theaforementioned breathing mask 11, the difference is that the forehead support frame includes a push-button against the forehead of the user, and a Installed between the mask unit and the push piece to adjust the adjustment joint of the push piece, the push piece changes the angle of the push piece relative to the mask unit with the adjustment of the adjustment joint, and is suitable for different Used by people with forehead height. However, this method does not change the position where the breathing mask is close to the root of the nose, and still cannot solve the problems caused when the breathing mask is close to the root of the nose, so it still cannot satisfy any user to obtain the most comfortable effect when wearing the breathing mask .

发明内容Contents of the invention
