在先技术中，通气设备包括风机、与风机排气口连通的排气腔以及连接在排气腔上的通气管，通过调节风机转速调节输出压力和流量。
然而，调节过程中排气腔内的气体容易产生湍流，导致排气腔产生噪音。
发明内容

通气设备是指可以提供正压气体以打开患者气管，从而帮助患者呼吸的设备，通气设备可以为通气治疗设备，例如呼吸机等。通气设备通常包括通气组件、通气管和控制装置。
通气管一端佩戴在患者身上，以与患者的气道连通，另一端连接在通气组件上。其中，通气管可以通过呼吸面罩佩戴在患者的面部，也可以插入患者的呼吸道内，本申请对通气管的佩戴方式不作限定。
通气组件可以吸入外部气体，并将外部空气排入通气管内。
控制装置与通气组件连接，使用时控制装置控制通气组件吸入外部气体，并以一定的输出压力和输出流量将外部气体通过通气管排入患者气管内，以打开患者气管，从而帮助患者呼吸。
其中，如图1和图2所示，通气组件包括壳体200和鼓风装置100。
鼓风装置100用于将气体从吸气口120吸入，并从排气口110排出。鼓风装置100可以与控制装置连接(图中未示出)，在控制装置的控制下调节输出压力和输出流量。
可选地，鼓风装置100包括风机，风机与控制装置连接，通过调节风机的转速调节鼓风装置100的输出压力和输出流量。
壳体200内部设有进气腔230、排气腔210和连通腔220，鼓风装置100的吸气口120与进气腔230连通，鼓风装置100的排气口110与排气腔210连通。鼓风装置100可以从进气腔230吸入气体，并将气体排入排气腔210内。
进气腔230可以设有与外部连通的进气口，排气腔210可以设有出气口211，通过出气口211连接通气管，这样鼓风装置100可以吸入由进气口进入进气腔230的外部气体(例如，空气)，并通过出气口211将外部气体排入通气管内。
其中，排气口110与出气口211错位设置，这样可以防止由排气口110进入排气腔210内的气体直接由出气口211进入通气管，从而使排气腔210可以保持一定压力。
通气组件工作时，由于鼓风装置100从进气腔230吸入气体，并将气体排入排气腔210内，因此排气腔210为高压腔，进气腔230为低压腔。实际使用过程中，一方面，当鼓风装置100的排气口110排出气体的流量和压力出现波动时，容易导致壳体200发生振动，从而产生噪音。另一方面，排气腔210内部的构造容易导致鼓风装置100排入的气体在排气腔210内产生湍流，湍流使壳体200发生振动，从而产生噪音。也就是说，在使用过程中，排气腔210内容易产生噪音。
连通腔220连通进气腔230和排气腔210，以使排气腔210内的部分气体通过连通腔220和进气腔230回流到鼓风装置100的吸气口120。连通腔220连通进气腔230和排气腔210后，由于排气腔210的压力大于进气腔230的压力，因此排气腔210的部分气体可以通过连通腔220进入进气腔230内，进而通过吸气口120吸入鼓风装置100中。也就是说，形成了一条从排气腔210到鼓风装置100吸气口120的泄压气路，当排气腔210内的气体出现压力波动或湍流时，可以通过泄压气路缓解压力波动或湍流带来的影响，从而 降低噪音。
可选地，连通腔220包括一个或多个子连通腔。连通腔220包括一个子连通腔时，子连通腔连通排气腔210和进气腔230。设置多个子连通腔时，每个子连通腔的结构均可根据使用工况进行设计，且多个子连通腔的排布方式也可以根据使用工况进行设计，使连通腔220的结构更加灵活，更容易满足实际使用需要。
设置多个子连通腔时，子连通腔的数量可以为两个、三个、四个等，本申请对此不作限定。
可选地，多个子连通腔沿气体的回流方向并联设置。多个子连通腔并联设置后，相当于泄压气路包括多个并联设置的子泄压气路，通过设置每个子泄压气路的结构调节每个子泄压气路的回流气体，使总的回流气体更加可控。
示例性地，连通腔220包括两个子连通腔，每个子连通腔均与排气腔210连通，且每个子连通腔均与进气腔230连通。
其中，两个子连通腔之间可以连通，也可以不连通。
可选地，多个子连通腔沿气体的回流方向串联设置。多个子连通腔串联后，可以使排气腔210到进气腔230之间的泄压气路的压力逐渐降低，使泄压气流更加平稳。
示例性地，沿气体回流方向，连通腔220包括第一子连通腔221和第二子连通腔222，第一子连通腔221和第二子连通腔222之间设置有隔板，隔板上设置有导流孔223，导流孔223的形状可以是格栅状、圆形、三角形、多边形等。
可选地，多个子连通腔中的至少两个并联，且多个子连通腔中的至少两个串联。
示例性地，子连通腔的数量为三个，其中两个子连通腔并联后与另一个子连通腔串联。当然，子连通腔的数量还可以为四个，其中两个子连通腔并联，剩余两个子连通腔串联，且并联后的子连通腔与串联后的子连通腔串联。
可选地，连通腔220和排气腔210之间设有隔板，隔板设有通气孔231。
可选地，连通腔220和进气腔230之间设有隔板，隔板设有通气孔231。
通过在相邻两个腔体之间设置隔板，并在隔板上设置通气孔231的方式，使排气腔210、连通腔220和进气腔230的压力逐渐降低，且可以通过设置 通气孔231的形状和位置使回流气流满足使用工况。
示例性地，如图3和图4所示，通气孔231为格栅状。当然，通气孔231也可以是圆形、三角形、多边形等。
壳体200同时设有通气孔231和导流孔223时，排气腔210内的气体可以经过通气孔、导流孔223进入进气腔230内。
可选地，壳体200还包括安装腔，鼓风装置100安装在安装腔内。将鼓风装置100安装在安装腔后，安装腔可以至少部分屏蔽鼓风装置100产生的噪音。
可选地，安装腔与进气腔230通过第一隔板分隔，鼓风装置100的支撑件穿过第一隔板，连接在进气腔230的侧壁上。
第一隔板的作用是将安装腔和进气腔230分隔，因此第一隔板的强度和刚度较弱，进气腔230的侧壁作为壳体200最外侧的一部分，不仅用于围成进气腔230，还作为壳体200的骨架，因此其强度和刚度较强，将鼓风装置100连接在进气腔230的侧壁上可以使鼓风装置100的固定更加牢固，并降低鼓风装置100运行过程中的振动。
示例性地，鼓风装置100包括三个支撑件，三个支撑件位于三角形的三个顶点上。这样使鼓风装置100的固定更加牢固。
可选地，支撑件通过减震件130连接在进气腔230的侧壁上。减震件130可以缓冲鼓风装置100运行过程中产生的振动，从而降低振动对壳体200的影响。
其中，减震件130可以为橡胶垫，也可以为其他减震器件，只要能起到缓冲鼓风装置100的振动即可。
最后，还需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者终端设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者终端设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者终端设备中 还存在另外的相同要素。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
