Description

呼吸面罩 技术领域
本申请涉及呼吸面罩技术领域，具体地涉及一种呼吸面罩。
背景技术
目前治疗阻塞性睡眠呼吸暂停低通气综合症(OSAHS，Obstructive sleep apnea hypopnea syndrome)的主要方法是持续正压通气(CPAP，Continuous Positive Airway Pressure)。CPAP通常需要患者长时间(例如整夜)佩戴呼吸面罩，因此佩戴舒适性对患者的体验影响非常大。如果患者感觉佩戴舒适度不够，就可能拒绝治疗，或者在佩戴时经常调整呼吸面罩的位置。尤其在夜间患者对呼吸面罩的无意识触碰，非常容易引起呼吸面罩内的气体泄露而影响治疗效果。
现有的大部分呼吸面罩都配备有前额支撑架。前额支撑架抵靠在患者的额头上，可以利用额头提供的支撑力来缓解呼吸面罩对面部的压迫感。但是，由于人种、年龄及个体的不同，对于不同的患者，其额头的高度不同。图1中的实线和虚线表示的额头100分别代表额头的高低区别。故在使用面罩时，需要不同的前额支撑高度以保证最合适的佩戴感，使患者能够获得舒适的佩戴体验。
目前，调节前额支撑架相对于额头的高度主要采用螺旋传动的原理，使用旋钮的旋转运动来实现前额支撑架上的前额支撑垫的伸缩，进而适应不同的前额高度。但这种调节机构包含的零部件数量较多，实现起来比较复杂；并且对制造工艺要求较高，制造成本居高不下。
发明内容
为了至少部分地解决现有呼吸面罩中存在的结构复杂、制造成本较高等问题，本申请提供一种呼吸面罩，能够提高调节前额支撑架的便捷性。
根据本申请的一个方面，提供了一种呼吸面罩，包括：框架；前额支撑架，所述前额支撑架可枢转地连接至所述框架，以使所述前额支撑架可朝 向患者前额或背离患者前额摆动；以及调节构件，所述调节构件可旋转地连接至所述框架，其中，通过所述调节构件的转动，驱动所述前额支撑架摆动。
本申请提供的呼吸面罩，包括可旋转地连接至框架的调节构件，通过旋转调节构件就可以调节前额支撑架相对于患者前额的高度。使用时，单手旋转调节构件就可以使前额支撑架摆动，患者可以根据个人感受寻找到最舒适的位置，无需他人帮助，操作起来非常方便。并且此调节方式的结构简单、零部件数量很少，因此制造工艺简单、制造成本较低。
在发明内容中引入了一系列简化形式的概念，这将在具体实施方式部分中进一步详细说明。本申请内容部分并不意味着要试图限定出所要求保护的技术方案的关键特征和必要技术特征，更不意味着试图确定所要求保护的技术方案的保护范围。
以下结合附图，详细说明本申请的优点和特征。

具体实施方式
在下文的描述中，提供了大量的细节以便能够彻底地理解本申请。然而，本领域技术人员可以了解，如下描述仅示例性地示出了本申请的优选实施例，本申请可以无需一个或多个这样的细节而得以实施。此外，为了避免与本申请发生混淆，对于本领域公知的一些技术特征未进行详细描述。
根据本申请的一个方面，提供一种呼吸面罩。图2-4从各个角度示出了根据本申请一个实施例的呼吸面罩200，其中，图2为根据本申请一个实施例的呼吸面罩的立体图；图3为图2中的呼吸面罩的主视图；图4为沿图3中的线A-A所截的呼吸面罩的剖视图。可以理解的是，虽然附图中以鼻罩型呼吸面罩为例来说明本申请的原理，但本文提供的呼吸面罩还可以为口鼻罩型、全脸型或鼻枕型等的呼吸面罩。如图2-4所示，呼吸面罩200可以包括框架(也称为面罩主体)210、调节构件220和前额支撑架230。
框架210主要用于支撑整个呼吸面罩200。框架210可以固定地连接或可拆卸地连接有衬垫240。衬垫240和框架210共同形成容纳患者的鼻部或者口鼻部的空腔。衬垫240也可以单独形成该空腔，在此实施例中框架210可以在衬垫240的外部支撑衬垫240。在使用时，衬垫240将与患者的脸部(包括脸颊、鼻梁、嘴巴上或下部等)接触，形成密封，以使该空腔与患者的鼻腔或者口鼻腔连通。框架210可以由刚性材料制成，或者也可以由柔性材料制成。衬垫240优选地由柔性材料制成。刚性材料可以是塑料、合金等，柔性材料可以是硅胶、凝胶、泡沫、气囊、纺织品等。呼吸面罩200被患者佩戴后站在患者的对面观看，框架210和衬垫240的形状不限于图中所示的大体三角形，还可以为梨形、梯形等等。框架210和衬垫240还可采用可以与口和/或鼻部形状相适配的任何其他形状。框架210可以设有输气接口211，以通过该输气接口211向呼吸面罩200内的空腔提供可供呼吸的气体。输气接口211具有沿着气流方向延伸的中心轴线P-P。此外，框架210上还可以设置有固定结构213，用于连接固定组件(图2中未示出)。固定结构213用于把呼吸面罩200固定在患者面部的适当位置，可以是现有的各种头带。头带上可以具有与框架210连接的结构，比 如扣、带魔术贴的绑带。
前额支撑架230在使用时抵靠在患者的额头上，以便将呼吸面罩200更加牢固且舒适地固定在患者的面部。前额支撑架230可枢转地连接至框架210，以使前额支撑架230可朝向患者前额或背离患者前额摆动。作为示例，前额支撑架230以枢轴O-O为轴可枢转。在该鼻罩型呼吸面罩中，优选地，前额支撑架230可枢转地(即可摆动地)连接至输气接口211，以使呼吸面罩的结构更加紧凑。但对于体积较大的呼吸面罩(例如全脸面罩或口鼻面罩等)，前额支撑架230可能与输气接口211分开地设置在框架210上。枢轴O-O沿着人体的左右方向延伸。前额支撑架230绕枢轴O-O枢转(沿着图4中的箭头N所示的方向枢转)时，可以相对于前额调整前额支撑架230的高度。前额支撑架230与框架210之间的连接可以是不可分拆式的或可分拆式的。前额支撑架230具有第一连接部231。前额支撑架230通过该第一连接部231连接至框架210。前额支撑架230还可以包括连接臂234和前额支撑垫232。连接臂234从第一连接部231大致沿着鼻梁延伸至前额附近。柔软的前额支撑垫232设置在连接臂234的靠近前额的端部，用于抵靠在患者的前额上。调节前额支撑架230的高度实际上是调整前额支撑垫232相对于前额的高度。
前额支撑架230与框架210之间的枢转连接方式可以为多种。在一个优选实施例中，前额支撑架230具有第一连接部231。框架210具有第二连接部215。第一连接部231和第二连接部215配合形成球窝连接结构。在一个优选实施例中，第一连接部231呈截球状，第一连接部231可枢转地容纳在第二连接部215中。截球是指使用两个平行的平面去截球形，位于两个平行平面之间的部分为截球。当然，也可以反过来，将第二连接部215设计成容纳在第一连接部231中的结构。但是，相比于图示的优选方式，第二连接部215容纳在第一连接部231中的设计会存在以下问题：内部的第二连接部215可能要设计得较长，以便给外部的第一连接部231留出足够的枢转空间，并且第一连接部231也没有充分利用空腔内的空间，这样会导致整个呼吸面罩200的外形较大，降低佩戴的舒适度。第一连接部231和第二连接部215之间球面可以采用过盈连接方式，以保证两者连接的气密性。
在球窝连接的情况下，为了限制前额支撑架230的摆动方向，例如使 前额支撑架230以枢轴O-O为轴进行枢转，前额支撑架230和框架210上分别设置有相互配合的限位部。图6为图2中的呼吸面罩被去除弯管组件和调节构件后的剖视图，图6相对于图2-4移除了调节构件220和弯管组件250，并露出了前额支撑架230上的限位部233(限位槽)以及框架210上的限位部217(限位块)。前额支撑架230摆动时，限位块217沿着限位槽233滑动。限位部还可以采用各种其他方式，例如设置在前额支撑架230和框架210上的相互匹配的限位块和限位槽、或者相互匹配的平面(平面可以垂直于枢轴O-O)等等。通过限位部，前额支撑架230与框架210之间虽然采用球窝连接，但只具有前额高度调节方向的自由度。
除了上述球窝连接结构之外，前额支撑架230还可以采用铰链等可枢转地连接至框架210。作为示例，铰链可以设置在框架210的外表面上，前额支撑架230通过该铰链连接到框架210。但相比于上述优选方式，这种铰链连接的结构比较复杂，不易拆洗，并且使呼吸面罩200的整体外观不平整。
呼吸面罩200还可以包括弯管组件250。弯管组件250连通至输气接口。压力支持设备(例如呼吸机)通过输气管路(未示出)与弯管组件250相连，以便输入适当压力的气体进入呼吸面罩200的空腔，进而进入患者的气道。供给患者的气体可以是现有技术已知的任何适当的呼吸气体。弯管组件250可以为本领域中常用的各种弯管组件。输气管路可以本领域常用的波纹软管。对于图2-4中的优选方式，前额支撑架230连接至输气接口211，调节构件220也可以连接至输气接口211。前额支撑架230的第一连接部231上设置有允许气体通过输气接口211的气流通道。弯管组件250可以连接至前额支撑架230的第一连接部231，并与第一连接部231的气流通道连通。在第二连接部215容纳在第一连接部231中的实施中、以及在前额支撑架230通过铰链连接到框架210的实施例中，弯管组件250可以直接连接至输气接口211。
需要说明的是，本申请所涉及的方位术语，例如“前”、“后”、“上”、“下”、“左”、“右”、“外”、“内”、“远”、“近”等都是相对于佩戴该呼吸面罩200且头部直立的患者而言的。就图3-4摆放位置而言，衬垫240相对于弯管组件250处于患者的近端，而弯管组件250相对于衬垫240处于患者的远端。
实施例一
在本申请的一种实施例一中，本申请提供的呼吸面罩可以包括具有调节斜面的调节构件，通过调节斜面与前额支撑架上的接合部的配合，将调节构件的旋转转换为前额支撑件的摆动，通过旋转调节构件就可以调节前额支撑架相对于患者前额的高度。
下面将对实施例一中用于调节前额支撑垫的高度的调节构件220进行详细描述。调节构件220可旋转地连接至框架210。可选地，所述调节构件220和所述框架210中的其中一个上可以设置有载体部件，所述调节构件220和所述框架210中的另外一个设置有沿着所述载体部件运动的配合部件。其中，上述载体部件可以包括：卡槽，该卡槽可以与相应的配合部件形成卡扣式连接；或者，上述载体部件可以包括：轨道，该轨道可以与相应的配合部件形成滑动连接。
图5为图4中的调节构件处的局部放大图，在一个优选实施例中，如图5所示，调节构件220上设置有第一卡槽223，框架210上设置有第二卡槽219，第一卡槽223和第二卡槽219可相互卡合。调节构件220通过第一卡槽223和第二卡槽219可旋转地连接至框架210。通过第一卡槽223相对于第二卡槽219的旋转，使调节构件220和框架210可相对旋转。作为示例，第一卡槽223和第二卡槽219中的至少一个呈环形，以使第一卡槽223和第二卡槽219中的一个可以相对于另一个可旋转。在调节构件220连接至输气接口211的实施例中，第一卡槽223和/或第二卡槽219可以沿输气接口211的周向延伸，以使调节构件220以输气接口211为轴可旋转。第一卡槽223和第二卡槽219中的至少一个可以是沿着输气接口211的周向连续设置的环形槽。调节构件220和框架210还可以采用其他配合方式来实现两者的相对旋转，例如，调节构件220和框架210中的其中一个上可以设置环形轨道，调节构件220和框架210中的另外一个上可以设置沿着该轨道可滑动的任何配合部，例如凸出部、卡勾部或齿等等。
调节构件220还具有调节斜面。调节斜面与参考平面成锐角。本申请实施例所提到的参考平面为平行于枢轴O-O的竖直平面，该参考平面为一假想面，并未在图中示出，但参照图4可以理解，该参考平面为垂直于纸面的竖直平面。当患者佩戴该呼吸面罩时，参考平面平行于患者的面部。在图4中，调节斜面可以包括远离框架210的远端表面221，该远端表面 221是倾斜面。该远端表面221与该参考平面成锐角。前额支撑架231具有接触调节斜面(在该实施例中为远端表面221)的接合部235。由于该调节斜面的存在，使得调节构件220沿着与患者的面部垂直的方向具有厚度差。这样，通过调节构件220的转动可以驱动前额支撑架230摆动，进而调节前额支撑架230相对于前额的高度。患者佩戴上该呼吸面罩200之后时，旋转调节构件220时，调节构件220的调节斜面会驱动前额支撑架230上的接合部235，从而带动前额支撑架230沿着箭头N所示的方向摆动，实现前额支撑架230的高度调节。患者无需他人帮助，单手旋转调节构件220就可以根据个人感受寻找到最舒适的位置，操作起来非常方便。调节斜面相对于参考平面的斜率可以根据前额支撑架230所需要的高度调节范围来设计。由此可见，调节构件220通过巧妙的设计来实现前额支撑架230的高度调节，其结构简单、制造工艺简单、因此可以节约成本。
由于调节斜面仅包含一个斜面(即远端表面221)与接合部235接触，每个接合部235仅能形成一个接合点，前额支撑架230可包括多个接合部235，来控制前额支撑架230的摆动。多个接合部235可以为设置在前额支撑架230上的多个凸起。如图2所示，两个凸起在前额支撑架230上相对设置。接合部235还可以包括更多个凸起。
此外，本申请结合图7-8还提供了另外优选的调节方式，图7为根据本申请一个实施例的呼吸面罩的立体图，图8为图7中的呼吸面罩的剖视图。除了调节构件220’和与调节构件220’配合的接合部之外，图7-8中的呼吸面罩200’与前述的呼吸面罩200基本相同。对于相同或相似的部件，图7-8中将采用与前述实施例相同的附图标记。本文仅针对不同之处进行详细描述。如前所述的，调节斜面仅包括一个斜面时需要设置多个接合部来控制前额支撑架230的摆动。在该优选实施例中，调节构件220’的内表面开有环形斜槽225。环形斜槽225可以设置在调节构件220’的面向第一连接部231的侧面(即调节构件220’的内表面)上。环形斜槽225环绕第一连接部231。环形斜槽225相对于上述参考平面倾斜设置。该环形斜槽225具有相对设置的第一侧壁225a和第二侧壁225b。第一侧壁225a和第二侧壁225b之间的空间即为该环形斜槽225。第一侧壁225a和第二侧壁225b均与上述参考平面成锐角。调节斜面可以包括该第一侧壁225a和第二侧壁225b。接合部235’的至少一部分设置在环形斜槽225内。接合部235’沿环形斜槽可滑动。接合部235’与第一侧壁225a和第二侧壁225b均 接触，从而通过一个接合部235’就能够控制前额支撑架230的摆动。当然，也可以设置多个接合部235’，来分担控制前额支撑架250摆动的作用力，延长其使用寿命。接合部235’可以如图7-8中所示地设置在调节构件220’的内侧，以使呼吸面罩200’的外观平整。接合部235’可以设置在连接臂254上，如图8所示。接合部235’还可以设置在第一连接部231上或者其他任何合适的位置处。
在又一组实施例中，图9为根据本申请一个实施例的呼吸面罩的立体图；图10为图9中的呼吸面罩的剖视图，如图9-10所示，调节构件220”的调节斜面可以包括面向框架210的近端表面229，该近端表面229是倾斜面。该近端表面229可以与参考平面(平行于患者面部的平面)成锐角。对于该呼吸面罩200”中与前述呼吸面罩200和呼吸面罩200’相同或相似的部件，将采用与前述实施例相同的附图标记，并且省略对相同或相似部件的详细描述。此处将主要针对不同之处进行详细描述。此外，为了与近端表面229配合，调节构件220”相对于框架210”的旋转平面也是倾斜的。该旋转平面为调节构件220”旋转时所在的平面，其可以与参考平面成锐角。作为示例，框架210”的接触所述近端表面229的端面不再如常规部件一般制作成平行于参考平面，而是与参考平面成锐角。框架210”的上述端面的倾斜角度不必须与近端表面229的倾斜角度相同。可选地，框架210”的上述端面也可以与参考平面平行，而是使框架210”的用于连接调节构件220”的卡槽或滑轨等倾斜设置，这样也可以实现调节构件220”相对于框架210”的旋转平面倾斜。沿着垂直于患者面部的方向，调节构件220”存在厚度差，并且调节构件220”相对于框架210”的旋转平面也相对于参考平面倾斜，两者共同作用来调节前额支撑架250的支撑高度。
需要说明的是，图9-10所示的调节方式可以与上述的各种实施例相结合。例如，可以将图2-6中的调节构件220的近端表面设计成倾斜的，并且还适应性地使调节构件220相对于框架210的旋转平面(例如相对于参考平面)倾斜。类似地，可以将图7-8中的调节构件220’的近端表面设计成倾斜的，并且还适应性地使调节构件220’相对于框架210的旋转平面(例如相对于参考平面)倾斜。
虽然在上述实施例中，调节构件220、220’和220”都呈环形，但是调节构件220、220’和220”的形状不限于此，其可以为能够可旋转地连接至输气口211和211”的各种形状。例如，调节构件220、220’和220”的外侧 壁可以为棱柱、棱台等形状，内侧壁可以大体上成圆柱形，只要能够实现其功能即可。调节构件220、220’和220”的外侧壁上可以设置有围绕调节构件220、220’和220”布置的多个齿，以方便手指拨动调节构件220、220’和220”使其旋转。
实施例二
在本申请的一种实施例二中，本申请提供的呼吸面罩可以通过调节构件和前额支撑件上的调节斜轨道和突出部的相互配合，将调节构件的旋转转换为前额支撑件的摆动，通过旋转调节构件就可以调节前额支撑架相对于患者前额的高度。
图11-15从各个角度示出了实施例二的呼吸面罩200的部件，图11为根据本申请一个实施例的调节构件及框架的剖视图；图12为根据本申请一个实施例的前额支撑架和框架的分解图，图13为根据本申请一个实施例的框架的立体图，图14为根据本申请一个实施例的前额支撑架的立体图；图15为根据本申请一个实施例的前额支撑架和调节构件的分解图。
下面将对实施例二中用于调节前额支撑垫的高度的调节构件220进行详细描述。调节构件220可旋转地连接至框架210。可选地，所述调节构件220和所述框架210中的其中一个上可以设置有载体部件，所述调节构件220和所述框架210中的另外一个设置有沿着所述载体部件运动的配合部件。其中，上述载体部件可以包括：卡槽，该卡槽可以与相应的配合部件形成卡扣式连接；或者，上述载体部件可以包括：轨道，该轨道可以与相应的配合部件形成滑动连接。
在一个优选实施例中，如图11所示，调节构件220上设置有第一卡槽223，框架210上设置有第二卡槽219，第一卡槽223和第二卡槽219可相互卡合。调节构件220通过第一卡槽223和第二卡槽219可旋转地连接至框架210。通过第一卡槽223相对于第二卡槽219的旋转，使调节构件220可相对于框架210旋转。作为示例，第一卡槽223和第二卡槽219中的至少一个呈环形，以使第一卡槽223和第二卡槽219中的一个可以相对于另一个可旋转。在调节构件220连接至输气接口211的实施例中，第一卡槽223和/或第二卡槽219可以沿输气接口211的周向延伸，以使调节构件220可以绕输气接口211旋转。第一卡槽223和第二卡槽219中的至少一个可以是沿中的至少一个的周向连续设置的环形槽。调节构件220和框架210 还可以采用其他配合方式来实现两者的相对旋转，例如，调节构件220和框架210中的一个上可以设置环形轨道，调节构件220和输气接口211中的另一个上可以设置沿着该环形轨道可滑动的任何配合部，例如凸出部、卡勾部或齿等等。
调节构件220还可套设在前额支撑架230的第一连接部231上。这样第一连接部231的外侧壁与调节构件220的内侧壁至少有一部分相对。该第一连接部231的外侧壁和该调节构件220的内侧壁的其中一个上可以设置有突出部，另一个上设置有调节斜轨道。在一个实施例中，突出部设置在调节构件220上，且调节斜轨道设置在前额支撑架230上。在另一个实施例中，可以反过来，将突出部设置在前额支撑架230上，且将调节斜轨道设置在调节构件220上。在调节前额支撑架相对于前额的高度方面，这两种设置方式的原理基本相同，因此，下文结合附图仅对其中一种设置方式进行详细描述。而本领域的技术人员根据以下描述可以了解另一种设置方式。
调节构件220的内侧壁上设置有突出部221，见图11和15。第一连接部231的外侧壁上设置有调节斜轨道236，见图12、14和15。调节斜轨道236环绕第一连接部231。调节斜轨道236大体上呈环形。突出部221沿着调节斜轨道236可滑动。作为示例，突出部221可以为突出于调节构件220的内侧壁的球头。球头可容纳在调节斜轨道236中，以沿着调节斜轨道236滑动。突出部221还可以具有其他构造，只要能够沿着调节斜轨道236滑动即可。调节斜轨道236相对于参考平面倾斜。本文所提到的参考平面为平行于枢轴O-O的竖直平面，该参考平面为一假想面，并未在图中示出，但参照图4可以理解，该参考平面为垂直于纸面的竖直平面。当患者佩戴该呼吸面罩时，参考平面平行于患者的面部。参见图12，沿着第一连接部231的周向方向，该调节斜轨道236相对于第一连接部231的近端的高度h逐渐变化。这样，当调节构件220转动时，突出部221会滑动到调节斜轨道236的不同位置处，驱动前额支撑架230摆动(即沿着箭头N所示的方向摆动)，进而调节前额支撑架230相对于前额的高度。患者无需他人帮助，单手旋转调节构件220就可以根据个人感受寻找到最舒适的位置，操作起来非常方便。调节斜轨道236相对于参考平面的斜率可以根据前额支撑架230所需要的高度调节范围来设计。由此可见，调节构件220通过巧妙的 设计来实现前额支撑架230的高度调节，其结构简单、制造工艺简单、因此可以节约成本。
在球窝连接的情况下，为了限制前额支撑架230的摆动方向，例如使前额支撑架230以枢轴O-O为轴进行枢转，前额支撑架230和框架210上分别设置有相互配合的限位部。参见示出了框架210的图13以及示出前额支撑架230的图14，前额支撑架230上的限位部233为限位凸起，框架210上的限位部217为限位槽。限位凸起238与限位槽217的位置相对应。前额支撑架230枢转时，限位凸起238沿着限位槽217滑动。限位部还可以采用各种其他方式，例如限位凸起和限位槽在前额支撑架230和框架210上的位置互换，或者在前额支撑架230和框架210上设置相互匹配、或者相互匹配的平面(平面可以垂直于枢轴O-O)等等。通过限位部，前额支撑架230与框架210之间虽然采用球窝连接，但只具有前额高度调节方向的自由度。但是，如后文将要描述地，前额支撑架230的第一连接部231的外侧壁或调节构件220的内侧壁上还设置有沿各自的周向延伸的调节斜轨道，因此，在采用相互匹配的平面来限制前额支撑架230仅以枢轴O-O为轴枢转时，会增大设计难度，但本申请并不排除这种设置方式。限位凸起238与限位槽217的配合方式会使限位部的结构相对简单。
优选地，调节构件220可拆卸地连接至前额支撑架230。前额支撑架230与框架210也可以采用可拆卸的连接方式。呼吸面罩需要经常清洗，呼吸面罩包含的各个部件之间能够拆解开，对于清洗来说很有帮助。在本申请的优选实施例中，第一连接部231的外侧壁和调节构件220的内侧壁中设置有调节斜轨道的侧壁上设置开槽。以图示实施例为例，参见图15，前额支撑架230的第一连接部231的外侧壁上设置有调节斜轨道236和开槽237。开槽237具有第一端和第二端。开槽237的第一端连接至调节斜轨道236。开槽237的第二端延伸至该外侧壁的边缘。由于调节斜轨道236与开槽237连通，因此突出部221可以沿开槽237可滑动进入调节斜轨道236中，或者从开槽237的第二端脱离开槽237，进而将调节构件220从前额支撑架230上拆卸下来。通过开槽237，调节构件220可以方便地与前额支撑架230拆解开，并且安装时只要将突出部221与开槽237对准，然后滑入至调节斜轨道236即可。调节斜轨道设置在调节构件220上的实施例与上述实施例类似，即将开槽设置在调节构件220的内侧壁上并连接至 调节斜轨道，为了简洁，本文不再赘述。
可选地，在图示实施例中，开槽237与调节斜轨道236垂直。但是，开槽237还可以不垂直于调节斜轨道236。开槽237与调节斜轨道236可以成一定角度。虽然相比于开槽237与调节斜轨道236垂直的实施例，开槽237不垂直地设置会使得结构稍微复杂些，但不垂直的设置也会降低突出部221意外脱离开槽237的几率。
进一步优选地，上文所提到的限位部可以包括设置在第一连接部231的外侧壁上的限位凸起、以及相对应地设置框架210上的限位槽。对于限位凸起和限位槽的配合方式在上文已经详细描述，这里不再赘述。值得一提的是，在调节斜轨道236和开槽237设置在前额支撑架230的第一连接部231的外侧壁上的实施例中，限位凸起238优选地设置在开槽237的两侧，如图14-15较佳地示出。考虑到佩戴的舒适性，呼吸面罩的设计得越来越小巧，对于第一连接部231的有限壁厚，将限位凸起238设置在开槽237的两侧可以增加开槽237的深度，在调节构件220的前额支撑架230的安装和拆卸过程中，更容易使突出部221与开槽237对准，因此安装和拆卸起来更加方便、快捷。
虽然在上述实施例中，调节构件220都呈环形，但是调节构件220的形状不限于此，其可以为能够可旋转地连接至输气口211的各种形状。例如，调节构件220的外侧壁可以为棱柱、棱台等形状，内侧壁可以大体上成圆柱形，只要能够实现其功能即可。调节构件220的外侧壁上可以设置有围绕调节构件220布置的多个齿，以方便手指拨动调节构件220使其旋转。
本申请已经通过上述实施例进行了说明，但应当理解的是，上述实施例只是用于举例和说明的目的，而非意在将本申请限制于所描述的实施例范围内。此外本领域技术人员可以理解的是，本申请并不局限于上述实施例，根据本申请的教导还可以做出更多种的变型和修改，这些变型和修改均落在本申请所要求保护的范围以内。本申请的保护范围由附属的权利要求书及其等效范围所界定。
