具体实施方式
以下结合附图对本申请的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。
实施例一
本申请提供了一种湿化罐，其中，湿化罐包括具有腔体的罐体100、插入腔体内的接头管200以及连通于接头管200出口端的至少两个支管300。
罐体100具有用于容纳液体的腔体，例如可以容纳水；接头管200插入罐体100的腔体中，其位于腔体外部的一端可以连接于导气管，从而可以将气体输入到腔体中；支管300从接头管200朝向不同的方向延伸，可以将来自接头管200的气流朝向腔体中不同的方向吹送，使得气体到达腔体中更多的位置，这可以避免腔体中存在气体吹拂不到的位置，避免出现气流死区，提高腔体内部气体流动性，延长气体流动路径，从而提高气体湿化效果。
其中，罐体100上连接有排气管105，排气管105可以排出湿化后的气体，并且排气管105可以连接于导气管，以将气体输出到目标位置。
进一步地，接头管200可以穿过罐体100的侧壁102，接头管200的出口端连接有两个水平延伸的支管300，两个支管300和接头管200形成Y型三通管。参考图2-图8所示，接头管200仅连接有两个支管300，并且支管300位于接头管200的出口端，接头管200和支管300大致形成为Y型的三通管，两个支管300的朝向彼此形成夹角，相比于仅存在一个接头管200，这可以使得气流向两侧输送，到达更多的位置。当然，在其他实施方式中，接头管200在出口端以外的位置也可以连接支管300，并且支管300可以向上或向下倾斜延伸。
进一步地，腔体中设置有朝向支管300的出口端的偏斜板109，偏斜板109被配置为改变支管300的出口流出气体的方向。支管300排出的气体可以吹送到偏斜板109中，偏斜板109可以引导改变气流原来的方向，使得气流被分散为更多的方向，并进一步将气流输送到腔体中的更多位置，加强腔体中的气流循环，避免出现死区。
其中，两个偏斜板109彼此靠近的一端间隔形成流道。如图5-图8所示，偏斜板109之间存在间隔而形成流道，这允许两个支管300排出的气流从此处穿过。
并且，两个偏斜板109彼此远离的一端均连接于罐体100的侧壁102。两个偏斜板109和部分的侧壁102围成具有流道出口的空间，来自支管300的气流在该空间中循环流动并从流道排出，在此结构中，气流可以到达接头管200附近的侧壁102处，避免此处形成死区。
另外，偏斜板109连接于罐体100的顶壁101，并且偏斜板109与罐体100的底壁103间隔。从支管300吹送到偏斜板109上的气流，可以在改变方向后从偏斜板109的下侧边缘越过，以到达偏斜板109的另一侧。

另外，如图1所示，湿化罐包括连接于罐体100的顶壁101的排气管105，挡板104位于流道的排气管105的入口端之间。挡板104可以阻挡来自流道的气流直接到达排气管105的入口端处，使得气流一部分反向流动到达其他位置，并且从靠近底部的位置越过而接近罐体100底部的水。排气管105可以一体地连接于顶壁101，或者通过可拆卸的方式连接于顶壁101。
此外，排气管105的入口远离挡板104的一侧边缘连接有导流板106，排气管105的入口位于挡板104和导流板106之间，导流板106的下端朝向挡板104倾斜。如图4所示，排气管105的入口端部分地插入腔体中，导流板106可以连接于排气管105的部分边缘上，导流板106的下端朝向挡板104倾斜，导流板106和挡板104之间形成通道，避免气流沿着竖直向上的方向直接进入到排气管105中，在一定程度上延长了气流进入排气管105之前的路径。
其中，挡板104朝向排气管105凹陷。挡板104的两侧相对于中间部分朝向排气管105倾斜，形成中间凹陷的形式，挡板104与导流板106组成通道，以允许气流上升而进入到排气管105中。另外，参考图6所示，挡板104也可以形成为平板形式。

罐体100具有用于容纳液体的腔体，例如可以容纳水；接头管200插入罐体100的腔体中，其位于腔体外部的一端可以连接于导气管，从而可以将气体输入到腔体中；气孔203沿周向间隔地分布，这使得接头管200中的气体可以通过气孔203以不同角度的径向方向排出而进入到罐体100的腔体中，来自接头管200的气体可以沿着不同的方向到达腔体中的更多位置，这可以避免腔体中存在气体吹拂不到的位置，避免出现气流死区，提高腔体内部气体流动性，延长气体流动路径，从而提高气体湿化效果。
其中，罐体100上连接有排气管105，排气管105可以排出湿化后的气体，并且排气管105可以连接于导气管，以将气体输出到目标位置。
另外，多个气孔203沿接头管200的周向和轴向呈阵列分布。如图10和图13所示，在接头管200插入腔体的部分上，气孔203在接头管200的长度方向上间隔排列，并且如上所述，在接头管200的周向上间隔排列，形成气孔阵列，这样可以经过气孔203在更多的方向上排出气流，使得气流到达腔体中的更多位置。气孔203可以规则地排列，也可以不规则地排列。
此外，罐体100包括顶壁101，接头管200水平延伸并与顶壁101间隔设置。参考图11和图12所示，接头管200从罐体100的侧部(也就是侧壁102)插入腔体中，并且接头管200大致水平延伸(罐体100水平放置时)，罐体100的顶壁101与接头管200插入腔体的部分保持间隔，以避免顶壁101阻挡部分气孔203排出气体。
进一步的，顶壁101包括覆盖接头管200的弧形部110。参考图6和图12所示，顶壁101包括与接头管200的部分外周间隔的部分，即弧形部110，朝向弧形部110的气孔203排出的气体在弧形部110的引导作用下向两侧流动，这使得气流可以在顶壁101的内表面附近流动，即使得气流到达更多的位置。
此外，腔体中设置有与接头管200的出口端间隔的挡板104。参考图10和图11所示，接头管200的出口端朝向挡板104，从接头管200的出口端排出的气流将吹拂到挡板104的表面上，挡板104改变气流的方向，将气流引导到其他位置，延长了气体的流动路径，提升湿化效果。

挡板104可以连接于顶壁101，并且其下端可以与罐体100的底壁103保持间隔，以允许气流从挡板104的下侧越过，使得气流更靠近罐体100的底壁103，也就是更靠近罐体100底部的水，实现对气流的湿化作用。在其他实施方式中，挡板104的两侧或其他一侧可以连接于罐体100的侧壁102。
其中，挡板104朝向接头管200凹陷。挡板104朝向接头管200的表面为 凹陷的，其中，挡板104的边缘部分相对于中间部分朝向接头管200倾斜，形成中间凹陷的形式，接头管200的出口端排出的气流到达中间部分后，沿着倾斜的表面改变方向，可以反向到达接头管200出口端后侧的位置，延长流动路径。
进一步地，挡板104朝向接头管200的表面为弧形面，弧形面的中心轴线竖直延伸。参考图10，挡板104大致为弧形板，其中心轴线竖直延伸，达到挡板104的气流沿着弧形面改变方向以到达接头管200后侧位置。在其他实施方式中，挡板104的表面也可以为球形的凹陷，挡板104类似于部分的球壳状结构。
另外，排气管105的入口远离挡板104的一侧边缘连接有导流板106，排气管105的入口位于导流板106和挡板104之间，导流板106的下端朝向挡板104倾斜。参考图11所示，排气管105的入口端部分地插入腔体中，导流板106连接于排气管105的部分边缘上，导流板106的下端朝向挡板104倾斜，导流板106和挡板104之间形成通道，避免气流沿着竖直向上的方向直接进入到排气管105中，在一定程度上延长了气流进入排气管105之前的路径。
其中，接头管200位于腔体中的管口设置有密封壁。也就是说，接头管200的出口端是密封的，例如连接一个密封壁，避免气体在接头管200的出口端排出，而是仅仅通过接头管200外周上的气孔203排出气体。
此外，罐体100包括侧壁102，接头管200穿过侧壁102插入罐体100的腔体中。如上所述，接头管200水平地插入到罐体100的腔体中。在其他实施方式中，接头管200也可以与水平面形成一定角度。

另外，排气管105的入口靠近挡板104的一侧边缘连接有导流板106，导流板106位于挡板104和排气管105的入口端之间，导流板106的下端远离挡板104倾斜。参考图18所示，排气管105的入口端部分地插入腔体中，导流板106连接于排气管105的部分边缘上，导流板106的下端向挡板104倾斜，侧壁102和挡板104之间形成小于排气管105内径的通道，使得沿侧壁102流动的气流可以向上进入排气管105中，并且可以避免气流沿着竖直向上的方向直接进入到排气管105中，在一定程度上延长了气流进入排气管105之前的路径。
其中，接头管200穿过罐体100的侧壁102而水平延伸。如上所述，接头管200水平地插入到罐体100的腔体中。在其他实施方式中，接头管200也可以与水平面形成一定角度。
