可选地，所述电动空气组件20还包括第一流量传感器26，所述第一流量传感器26与所述外界空气接口22连接，以用于监测所述外界空气接口22的流量；其中，通过设置第一流量传感器26以用于实时检测外界空气接口22的流量，如此以使得医护人员可以根据第一流量传感器26的流量调节涡轮21的运行速度，进而调节混合后的气体的外界空气的比例。
可选地，所述电动空气组件20还包括第一过滤器27，所述第一过滤器27连接于所述外界空气接口22和所述第一降噪室23之间，以用于过滤经过 所述外界空气接口22的外界空气。其中，为了提高使用的安全性，可以通过在外界空气接口22和第一降噪室23之间设置过滤器，以过滤外界空气中的有害物质，进而避免外界空气中的有害物质混合后流向病人，以进一步保证治疗的安全性。
在本申请的一实施例中，结合参照图1，所述气动空气组件30还包括第一减压阀33，所述第一减压阀33与所述第一压力传感器32电性连接，所述第一减压阀33与所述气瓶接口31连通，以用于对经过所述气瓶接口31的气体进行减压；其中，由于不同病人所需要的治疗气体的压强不同，所以通过设置第一减压阀33可以根据病人的治疗需求调节气瓶接口31的气体进行减压，以达到满足病人治疗需求的气体压强，提高治疗的效果。
可选地，所述气动空气组件30还包括第一比例阀34，所述第一比例阀34与所述气瓶接口31和所述供氧组件10连通，所述第一比例阀34用于调节经过所述气瓶接口31的气体的流量，并与所述供氧组件10的氧气混合后输出至所述气体输出组件40；其中，由于不同病人所需要的治疗气体的氧气浓度不同，为了提高治疗效果，当该外接高压气瓶于气瓶接口31时，为了调节混合后的气体的氧气浓度，如此可以通过第一比例阀34调节经过所述气瓶接口31的气体的流量，以此来控制混合后的气体的氧气浓度，以满足不同病人治疗时所需要的氧气浓度。
可选地，所述气动空气组件30还包括第二过滤器35，所述第二过滤器35连接于所述气瓶接口31，以用于过滤经过所述气瓶接口31的气体。其中，为了提高使用的安全性，可以通过在气瓶接口31设置第二过滤器35，以过滤外接气体中的有害物质，进而避免气体中的有害物质混合后流向病人，以进一步保证治疗的安全性。
参照图1，在本申请的一实施例中，所述供氧组件10包括高压氧插接口11，低压氧插接口12，气源切换阀13以及氧气三通阀14，所述气源切换阀13分别与所述高压氧插接口11和所述低压氧插接口12连通，以用于切换所述高压氧插接口11和所述低压氧插接口12的导通，所述氧气三通阀14分别与所述气源切换阀13、所述电动空气组件20以及所述气动空气组件30连通，以用于将所述气源切换阀13的出气口分别与所述电动空气组件20或所述气 动空气组件30导通。其中，由于不同的氧气浓度对治疗效果不同，在使用时当高压氧气和低压氧气同时接入时，气源切换阀13会自动切换到高压氧气输入端，以使呼吸机优先使用高压氧气。反之当高压氧气未接入气路，低压氧气接入气路呼吸机则使用低压氧气进行工作。进而使得呼吸机可以同时连接多种气源规格的氧气气瓶，并根据治疗需求选择相应的气路导通，提高呼吸机使用的便捷性，拓展呼吸机的使用区域。而通过设置氧气三通阀14分别与电动空气组件20以及气动空气组件30连通，如此以可以根据相应的空气组件而打开氧气三通阀14相应的开口，如当涡轮21工作时，氧气三通阀14选择切换到阀口A打开，阀口B关闭，氧气直接接入第二降噪室24，与空气混合后经过流入后续气路部件。反之当涡轮21不工作，氧气三通阀14切换阀口A关闭，阀口B打开，氧气与气动空气组件30内的气体混合后，流入后续气路部件。如此以使得供氧组件10可以根据电动空气组件20和气动空气组件30的选择而打开相应的阀口，更加智能化。
此外，结合图2和图3，该气源切换阀13包括阀主体131和阀芯1322组件132，所述阀主体131内形成有过气腔131，所述阀主体131开设有连通所述过气腔131的第一气流通道131B、第二气流通道131C以及出气通道131D；所述阀芯1322组件132活动设于所述过气腔131内，并于所述第一气流通道131B和所述第二气流通道131C之间移动，以用于封堵所述第一气流通道131B和所述出气通道131D的导通或者封堵所述第二气流通道131C和所述出气通道131D的导通。可以理解的是，该阀芯1322组件132即可以直接通过气体压力流动以推动在阀主体131内来回运动，以达到选择性封堵第一气流通道131B和出气通道131D的导通或者封堵第二气流通道131C和出气通道131D的导通，当然该阀芯1322组件132也可以通过用户手动推动或者电动推动在阀主体131内来回运动。此外，该阀芯1322组件132既可以通过相对于阀主体131滑动的方式进行选择性封堵，也可以通过相对于阀主体131转动的方式进行选择性封堵，具体可由本领域技术人员根据具体情况进行选择。
进一步地，所述过气腔131包括依次连接的第一腔体段131a、第二腔体段131b以及第三腔体段131c，所述第一气流通道131B与所述第一腔体段131a连通，所述第二气流通道131C与所述第三腔体段131c连通，所述出气通道 131D与所述第二腔体段131b连通，所述阀芯1322组件132与所述阀主体131滑动连接，以可滑动封堵所述第二腔体段131b和所述第三腔体段131c的导通或者滑动封堵所述第一腔体段131a和所述第二腔体段131b的导通。其中，第一腔体段131a、第二腔体段131b以及第三腔体段131c呈直线依次排布，且该出气通道131D连接于第二腔体段131b，以便于加工且使氧气切换阀的整体可以设置较为紧凑，避免氧气切换阀的整体体积过大。同时当高压氧气和低压氧气同时接入气路，压力会顶住阀芯1322组件132向下运动。因此会阀芯1322组件132朝向第二气流通道131C方向推动，以封堵第二气流通道131C和出气通道131D的导通，从而保持第一气流通道131B处于优先导通的状态，当第一气流通道131B内的气体供完后，第二气流通道131C会推动阀芯1322组件132重新朝向第一气流通道131B方向推动，以封堵第一气流通道131B和出气通道131D的导通，而该阀芯1322组件132可以通过相对滑动的方式设置于过气腔131，如此以起到滑动封堵的作用，该安装方式较为方便，提高安装的效率。此外，需要说明的是，当阀芯1322组件132主要由气体压力进行推动时，该第一气流通道131B的通道的横截面积大于第二气流通道131C的横截面积，如此以使得第一气流通道131B的气流容量较大，以便于保证气体压力会顶住阀芯1322组件132向低压氧气气流通道方向运动。
进一步地，所述阀芯1322组件132包括弹性件1321，阀芯1322，第一密封构件1323以及第二密封构件1324，所述弹性件1321设于所述第三腔体段131c内，并与所述阀主体131固定；所述阀芯1322可在所述第一腔体段131a、所述第二腔体段131b以及所述第三腔体段131c之间往复滑动，并与所述弹性件1321弹性抵接；所述第一密封构件1323套设于所述阀芯1322，以在所述阀芯1322的带动下于所述第一腔体段131a和所述第二腔体段131b之间移动，以用于封堵所述第一腔体段131a和所述第二腔体段131b的导通；所述第二密封构件1324套设于所述阀芯1322，以在所述阀芯1322的带动下于所述第二腔体段131b和所述第三腔体段131c之间移动，以用于封堵所述第二腔体段131b和所述第三腔体段131c的导通。其中，该弹性件1321可以为弹簧，该弹簧的一端固定于阀主体131的第三腔体段131c内，而阀芯1322连接于弹簧的另一端，而该第一密封构件1323和第二密封构件1324可以为 密封垫圈，从而可以套设于阀芯1322的外侧壁。
而当氧气切换阀的第一气流通道131B未接入高压氧时，仅在第二气流通道131C接入低压氧时，此时该弹簧为未被压缩的状态时，且在弹簧的作用下顶住阀芯1322，从而该第一密封构件1323封堵第一腔体段131a和第二腔体段131b的导通，进而该第二气流通道131C与出气通道131D连通，以使低压氧从出气通道131D输出；
而当氧气切换阀的第二气流通道131C未接入低压氧时，仅在第一气流通道131B接入高压氧时，此时该弹簧会被高压氧气流所压缩，以使并使阀芯1322朝向第二气流通道131C滑动，从而使第二密封构件1324封堵第二腔体段131b和第三腔体段131c的导通，以使高压氧从出气通道131D输出；
而当高压氧和低压氧分别同时接入氧气切换阀的第一气流通道131B和第二气流通道131C时，由于高压氧的压强较大，如此会先压缩弹簧发生形变，并使阀芯1322朝向第二气流通道131C滑动，从而使第二密封构件1324封堵第二腔体段131b和第三腔体段131c的导通，以使高压氧从出气通道131D输出。而当高压氧供完后，施加于弹簧形变的外力消失，从而弹簧复位且在低压氧气流推动阀芯1322重新朝向第一气流通道131B滑动，以使第一密封构件1323封堵第一腔体段131a和第二腔体段131b的导通，进而该第二气流通道131C与出气通道131D连通，以使低压氧从出气通道131D输出。
结合参照图2和图3，在本申请的一实施例中，阀主体131包括壳体1311和底盖1312，所述壳体1311开设有让位口，所述底盖1312盖设于所述让位口，所述底盖1312与所述壳体1311配合形成所述过气腔131，所述壳体1311的侧壁开设有所述第一气流通道131B、所述第二气流通道131C以及所述出气通道131D。其中，该底盖1312可由通过螺钉连接的方式固定于壳体1311处，以围合形成过气腔131，该固定方式安装操作较为简单，而且易于进行拆卸，以便于阀芯1322组件132可以先从让位口安装于壳体1311内，再盖合底盖1312，方便后续对阀芯1322组件132进行维护保养。当然了，其它实施例中，也可以是销钉连接、铆钉连接等本领域常用的连接方式将底盖1312与壳体1311相固定。
进一步地，所述第一气流通道131B、所述出气通道131D以及所述第二 气流通道131C沿所述壳体1311朝向所述底盖1312的方向依次设置；所述氧气切换阀还包括辅助密封构件133，所述辅助密封构件133连接于所述阀芯1322组件132朝向所述底盖1312的一侧，以在所述第二气流通道131C和所述让位口之间往复移动。其中，为了保证过气腔131的密封性，如此在阀芯1322组件132朝向底盖1312的一侧设置辅助密封构件133，进而可以防止过气腔131内的气流从让位口的方向流出，以保证气流流动的稳定性，提高氧气切换阀使用的可靠性。
在本申请的一实施例中，参照图2和图3，所述氧气切换阀还包括高压氧进气管体134，低压氧进气管体135以及出气管体136，所述高压氧进气管体134与所述阀主体131连接，并与所述第一气流通道131B连通；所述低压氧进气管体135与所述阀主体131连接，并与所述第二气流通道131C连通；所述低压氧进气管体135与所述阀主体131连接，并与所述出气通道131D连通。其中，该高压氧进气管体134，低压氧进气管体135以及出气管体136可以与阀主体131为一体设置，如此以保证氧气切换阀整体结构的稳定性和支撑强度。而通过高压氧进气管体134，低压氧进气管体135以及出气管体136位于阀主体131外并分别与第一气流通道131B、第二气流通道131C和出气通道131D连通，以便于使得氧气切换阀与其他连接部件连接的便利性，提高安装的效率。
进一步地，所述高压氧进气管体134和所述低压氧进气管体135位于所述阀主体131的同一侧。其中该高压氧进气管体134和低压氧进气管体135位于阀主体131的同一侧，如此以便于医护人员在连接氧气气瓶时，可以仅在阀主体131的一侧便可以进行操作，便于操作，提高氧气切换阀安装的效率。
更进一步地，所述高压氧进气管体134的进气口的朝向和所述低压氧进气管体135的进气口的朝向背对设置；可以理解的是，当分别同时连接高压氧气瓶和低压氧气瓶时，两者的管路容易互相干涉，从而通过使高压氧进气管体134的进气口的朝向和低压氧进气管体135的进气口的朝向背对设置，如此以避免安装时以使高压氧气瓶的管路和低压氧气瓶的管路朝向不同的方向延伸，进而避免两者互相干涉，以进一步提高氧气切换阀使用的稳定性。
可选地，所述出气管体136与所述高压氧进气管体134设置于所述阀主体131的相对两侧。其中，该出气管体136与高压氧进气管体134分别设置阀主体131的相对两侧，如此使得进气方向和出气方向对称，以更便于医护人员进行精确安装，且连接时不会相互干涉，提高氧气切换阀的使用性。

可选地，所述供氧组件10还包括相连接的第二流量传感器17和第二比例阀18，所述第二流量传感器17均与所述气源切换阀13连通，以用于监测所述气源切换阀13的出口的氧气流量，所述第二比例阀18设置于所述气源切换阀13和所述氧气三通阀14之间，以用于调节从所述气源切换阀13流向所述氧气三通阀14的氧气流量。其中，由于不同病人所需要的治疗气体的氧气浓度不同，为了提高治疗效果，通过设置第二流量传感器17可以实时检测氧气的流量数值，并且通过第二比例阀18可以调节氧气的流量，如此以此来控制混合后的气体的氧气浓度，以满足不同病人治疗时所需要的氧气浓度。
参照图1，在本申请的一实施例中，所述气体输出组件40包括第三流量传感器41，空氧混合器42以及吸气阀43，所述第三流量传感器41分别与所述电动空气组件20和所述气动空气组件30连通，以用于接收所述混合后的气体；所述空氧混合器42与所述第三流量传感器41连通，并分别与所述供氧组件10、所述电动空气组件20以及所述气动空气组件30电性连接，所述空氧混合器42用于检测所述混合后的气体的氧浓度，并反馈控制所述供氧组件10、所述电动空气组件20以及所述气动空气组件30；所述吸气阀43与所述空氧混合器42连通。其中，该第三流量传感器41用于实时检测混合后的 气体流量，而该空氧混合器42用于检测所述混合后的气体的氧浓度，如此以使得医护人员可以实时了解用于病人治疗的气体的流量和氧气浓度，从而医护人员可以根据这两个数值分别调节控制供氧组件10、电动空气组件20以及气动空气组件30的流量和流速，以此来调节混合后的气体的流量和氧气浓度，以满足病人治疗时所需要的治疗需求，并通过吸气阀43进入病人肺部，完成吸气相。
进一步地，所述气体输出组件40还包括第二单向阀44，所述第二单向阀44分别与所述空氧混合器42和所述吸气阀43连通，以用于导向所述混合后的气体流向所述吸气阀43；其中，为了避免混合后的气体回流，从而在空氧混合器42和吸气阀43之间设置第二单向阀44，如此以防止混合后的气体回流至供氧组件10、电动空气组件20以及气动空气组件30内，进一步地提高气路***100使用的安全性。
可选地，所述气体输出组件40还包括自由呼吸阀45，所述自由呼吸阀45连接于所述空氧混合器42和所述吸气阀43之间，以用于接收外界空气流向所述吸气阀43。其中，自由呼吸阀45为单向阀，进气端与大气相连。当气路***100出现故障，不能向病人端输送气体或者气路堵塞时，自由呼吸阀45会打开，病人可以吸入大气，以防止病人因窒息而发生生命危险。
在本申请的一实施例中，参照图1，所述气路***100还包括相连接的雾化三通阀50和第一开关阀60，所述雾化三通阀50分别与所述供氧组件10和所述气动空气组件30连通，所述第一开关阀60用于与雾化器连接，以用于将所述供氧组件10的氧气或所述气动空气组件30的气体对雾化器内的药物进行雾化；其中，由于病人在使用呼吸机的过程中存在需要额外使用药物进行雾化进行治疗的需求，从而通过设置相连接的雾化三通阀50和第一开关阀60，该雾化三通阀50可以为电磁三通阀，而该第一开关阀60用于与雾化器连接，从而操作者可以设置使用何种气体(氧气/空气)作为雾化气体，雾化三通阀50会根据设置选择切换将气体接入第一开关阀60。雾化三通阀50也可根据设置选择默认某种气体(氧气/空气)为雾化气体，使通向这路的气体的阀门保持常开。第一开关阀60根据机器的指令，开启或者关闭来实现雾化开启或关闭，如此以使该气路***100具有雾化功能，提高呼吸机的使用性。
可选地，气路***100还包括呼气阀70、第二开关阀80以及第四流量传感器90，所述呼气阀70用于供病人进行呼气，所述第四流量传感器90与所述呼气阀70连接以用于检测所述呼气阀70的气体流量，所述第二开关阀80分别与所述第四流量传感器90和所述气体输出组件40连通，以用于将所述气体输出组件40的混合后的气体对所述第四流量传感器90进行导通。可以理解的是，呼气时病人肺部的气体经过呼气阀70排到大气中，以保持呼吸循环，而为了检测病人呼气时的气体流速，从而会同时设置第四流量传感器90进行检测，而由于病人呼气时的气体存在水汽，为了保证监测的准确性，同时通过将第二开关阀80接入气体输出组件40和第四流量传感器90，呼吸机会根据设置的频率控制第二开关阀80定时打开再关闭，使气体输出组件40的气流进入第四流量传感器90，吹出第四流量传感器90里面的水，以保证第四流量传感器90测出的数值的准确性。
