  • Atomization refers to the operation of dispersing a liquid into minute droplets through a nozzle or with a high velocity gas stream. A large number of dispersed droplets that are atomized can float in the air to increase the contact area with the object to be sprayed, thereby improving the spraying effect.

技术领域
本公开涉及喷洒技术领域，具体而言，涉及一种离心雾化结构及具有该离心雾化结构的喷洒装置、离心雾化装置、驱动装置及双驱动喷洒装置。
背景技术
雾化是指通过喷嘴或用高速气流使液体分散成微小液滴的操作。被雾化的众多分散液滴可以漂浮于空气中进而加大与被喷洒对象的接触面积，提高喷洒效果。液体雾化的方法有压力雾化，气体雾化，离心力雾化，及声波雾化等。指使液体经过特殊装置化成小滴，成雾状喷射出去。
离心力雾化是雾化盘在电机作用下高速转动，由于离心力的作用，使得液体在旋转的雾化盘表面上伸展为薄膜，并以不断增长的速度向盘的边缘运动，当离开盘的边缘时，液体即雾化为雾滴。现有的离心雾化装置，由于设计的局限，甩出的雾滴的颗粒大小不均匀，从而使得喷洒或浇灌不均匀，对药液产生一定的浪费。
公开内容
本公开提供一种离心雾化结构及具有该离心雾化结构的喷洒装置，至少能够使得雾化颗粒更加小、更加均匀。
本公开采用的公开是：一种离心雾化结构，包括离心雾化盘，离心雾化盘上开设有多条导流槽，各导流槽由离心雾化盘中央位置向边缘延伸；其创新在于：
离心雾化盘外侧设置有一环状体，环状体上沿其周向间隔设置有多个齿，各齿以环状体中心为基准向外呈放射状布置；环状体与所述离心雾化盘同轴设置，且该环状体与离心雾化盘之间在其径向上具有一间距。
本公开采用的另一公开是：一种喷洒装置，其创新在于：上述公开中离心雾化盘的中心与一电机输出轴传动连接。
上述公开中的有关内容解释如下：
上述公开中，每个齿在离心雾化盘径向上的最大尺寸定义为齿的长度，在垂直于该径向的方向上的最大尺寸定义为齿的宽度，齿的长度大于齿的宽度；齿在环状体的周向上间隔且均匀分布。
上述公开中，环状体与离心雾化盘之间的间距为1～20毫米，优选为1.5～15毫米，若间距太小，从离心雾化盘甩出的雾滴无法完全撕裂，达不到撕裂效果；若间距太大，雾滴失去动力，无法实现二次撞击进一步雾化。
上述公开中，相邻两个齿的根部之间通过弧形过渡，防止雾滴积聚于齿的根部。
上述公开中，齿的根部与环状体之间设置有倒角，使得齿与环状体之间的连接更加稳固。
上述公开中，离心雾化盘的直径为50～400毫米。
上述公开中，齿的长度为2～4毫米，如果齿长度太短，设计齿时会过密导致黏连，若齿长度太长，多个雾滴同时碰到一个齿上时，齿表面会形成液膜，导致下一个雾滴被液膜吸收，无法实现撞击雾化。
上述公开中，相邻齿之间的周向距离大于或等于2毫米，优选大于3毫米，优选大于4毫米，作用在于防止齿上的表面张力产生液膜，从而导致雾滴积聚在齿表面。
上述公开中，齿的径向横截面为梯形、矩形、或圆角结构，优选为梯形，以此实现最大面积 的碰撞，防止雾滴因为碰撞到齿靠近雾化盘的短边而返回导致无法通过齿；齿设置为圆角，易于生产制造；径向截面是过某个点与轴线垂直的截面。
上述公开中，离心雾化盘上过所述齿最长边的中点的半径与齿最长边之间的夹角为-7～7°，以导流槽曲线延伸切线方向与该半径的夹角为负，由于离心力和导流槽弧度的原因，导致从离心雾化盘甩出的雾滴方向为偏离其切线15～22°角，为了配合使得雾滴撞击于齿上的入射角都为45°左右，齿的角度设计为-7～7°，优选为0～7°，优选为0°，入射角为45°，有利于提高雾滴的撞击效果，使得雾化颗粒更加均匀。
上述公开中，环状体外涂布有电镀聚四氟乙烯层或纳米层。
上述公开中，离心雾化盘的转速为2000～50000转/分，优选为10000～50000转/分。
上述公开中，导流槽为阿基米德曲线状。
上述公开中，离心雾化盘转动设置，环状体相对固定设置，或者，环状体与离心雾化盘的旋转方向相反布置，当离心雾化盘与环状体转向相逆设置时，提高了离心雾化盘的相对转速，进一步提高雾化效果。
上述公开中，齿与导流槽的数量比为0.5：1～2：1，优选为1：1～1.8：1。
本公开工作原理及优点：本公开通过在离心雾化盘外围增设一环状体，环状体上对应于导流槽设置有齿，雾滴在甩出离心雾化盘之后撞击到齿上，实现精准的撞击，进一步雾化，提高了雾化颗粒的均匀度，同时，撞击减小了雾滴的平均粒径，至少能够达到30微米平均粒径的雾化效果，甚至10微米以下平均粒径的雾化效果，通过撞击，使得雾化更为充分，雾化颗粒更加均匀，浇灌喷洒更为均匀更易穿透，同时有效节约药液用量。
本公开包括提供一种离心雾化装置，包括离心雾化盘，离心雾化盘上开设有多条导流槽，各导流槽由离心雾化盘中央位置向边缘延伸；其创新在于：
所述离心雾化盘外侧设置有一环状体，该环状体与所述离心雾化盘同轴且相对转动设置，且该环状体与所述离心雾化盘之间在其径向上具有一间距；离心雾化盘旋转在其周围形成一正向风场，该正向风场绕离心雾化盘的中心顺时针或逆时针旋转；在工作状态下，环状体在其与离心雾化盘之间提供一反向风场，该反向风场的旋转方向与正向风场的旋转方向相反；反向风场和正向风场相互作用，在离心雾化盘与环状体之间形成一加速风场带；环状体上形成有多条气流带，各气流带在环状体的周向上间隔分布，各气流带对应于导流槽中甩出的液滴设置，气流带的气流方向与导流槽中甩出的液滴的运行方向相反。
上述公开中的有关内容解释如下：
上述公开中，液滴从离心雾化盘边缘甩出时具有相对于静止空气的第一速度v1，正向风场的方向与离心雾化盘的旋转方向相同，正向风场具有第二速v2，其相对减小了液滴与空气的相对速度，使得液滴与空气的相对速度为v1-v2，而反向风场的方向与正向风场方向相反，并具有第三速v3，反向风场对正向风场起到减弱或者逆转作用，大幅度提高了液滴与空气的相对速度，使得液滴与空气的相对速度为v1-v2+v3，使得空气流动速度增加，即液滴切割速度增加，雾化的液滴粒径减小。同时，气流带的气流方向与导流槽中甩出的液滴的运行方向相反，以此，可以更好地实现液滴的切割，提高液滴与空气的相对速度，提高液滴的雾化效果。
上述公开中，反向风场的强度大于正向风场的强度，使得加速风场带的方向与反向风场相同，此时，实现的加速风场带，更大程度的提高了液滴与空气的相对速度，使得雾化效果倍增。在其他情况下，反向风场的强度也可以等于或者小于正向风场的强度，此时，加速风场带虽然没有实现方向上的逆转，但是仍然减弱了正向风场，提高了液滴与空气的相对速度，雾化效果仍然比较理想。
上述公开中，环状体与离心雾化盘之间在其径向上的间距为1～20毫米，如果间距过小，将无法提供加速风场带，如果间距过大，加速风场带没有效果。
上述公开中，环状体相对固定设置，环状体内沿其周向开设有一圈导气槽，环状体的内周面上开设有多个气孔，气孔与导气槽连通，各气孔在环状体的周向上间隔分布，气流带沿所述气孔的延伸方向从导气槽向外导出。

优选地，导气槽与一气泵的出气口连通。
优选地，在垂直于离心雾化盘轴线的气孔的轴向截面上，气孔的轴线与离心雾化盘上过该轴向截面上孔壁投影线中心的半径之间的夹角为60～75°。
优选地，气孔出气口的孔径为1～3毫米。
优选地，气孔与导流槽的数量比为1：1～2：1。
优选地，环状体上涂布有电镀聚四氟乙烯层或纳米层，使得环状体上具有不沾效果，防止液滴积聚，提高雾化效果。
上述公开中，环状体相对于离心雾化盘反向旋转，环状体上沿其周向间隔设置有多个齿，各齿以环状体中心为基准向外呈放射状布置，齿靠近所述离心雾化盘的一侧产生所述气流带。
优选地，齿的径向截面为矩形或弧形；
当齿的径向截面为矩形时，离心雾化盘上过矩形长边中点的半径与该长边之间的夹角为0～60°；
当齿的径向截面为弧形时，离心雾化盘上过弧形中点的半径与过弧形中点的切线之间的夹角为0～60°。
优选地，相邻两个齿之间的周向距离大于2毫米，优选大于3毫米，优选大于4毫米，作用在于防止齿上的表面张力产生液膜，从而导致液滴积聚在齿表面。
优选地，齿在其放射方向上的尺寸为2～4毫米，在其轴向上的尺寸大于3毫米，垂直于放射方向的尺寸为0.5～1毫米；如果齿在其放射方向上的尺寸太短，设计齿时会过密导致黏连，若齿在其放射方向上的尺寸太长，多个液滴同时碰到一个齿上时，齿表面会形成液膜，导致下一个液滴被液膜吸收，无法实现二次撞击雾化；当所述齿的径向截面为弧形时，该弧对应的弦长即为该齿在放射方向上的尺寸。
优选地，环状体与离心雾化盘之间在其径向上的间距为1～20毫米，优选为3～10毫米，如果间距过小，将无法提供加速风场带，如果间距过大，加速风场带没有效果，加速风场带无法实现其提高液滴相对速度的作用，同时，也无法实现进一步撞击的效果。优选地，所述齿在环状体的周向上间隔且均匀分布。
优选地，环状体及齿上涂布有电镀聚四氟乙烯层或纳米层，使得环状体及齿上具有不沾效果，防止液滴积聚，提高雾化效果。
优选地，离心雾化盘的转速为2000～50000转/分，优选为10000～50000转/分，所述环状体的转速为2000～50000转/分，优选为10000～50000转/分。
优选地，齿与导流槽的数量比为0.5：1～2：1，优选为1：1～1.8：1。
上述公开中，所述离心雾化盘的直径为50～300毫米。
上述公开中，导流槽为阿基米德曲线状。
本公开工作原理及优点：本公开通过在离心雾化盘外围增设一环状体，环状体相对于离心雾化盘同轴且相对转动设置，在工作状态下，环状体产生的风场与离心雾化盘自身产生的风场方向相反，虽然离心雾化盘自身产生的风场依然存在，但是由于环状体产生的风场减弱或者逆转了离心雾化盘自身的风场，形成的加速风场带使得离心雾化盘与空气气流的相对转速大大提高，无需提高雾化盘的转速，即可提高液滴相对于空气的相对速度，使液滴平均粒径减小，使得雾化更为充分，雾化颗粒更加均匀，浇灌喷洒更为均匀更易穿透，同时有效节约药液用量。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
下面结合附图及实施例对本公开作进一步描述：
参见附图1及附图2所示，一种离心雾化结构，包括离心雾化盘1，离心雾化盘1上开设有多条导流槽11，各导流槽11由离心雾化盘1中央位置向边缘延伸，导流槽11出口开放于离心雾化盘1的边缘。
离心雾化盘1外侧设置有一环状体2，该环状体2与离心雾化盘1同轴设置，且该环状体2与离心雾化盘1之间在其径向上具有一间距3。环状体2上沿其周向间隔且均匀设置有多个齿21，齿21对应于导流槽11设置，各齿以环状体中心为基准向外呈放射状布置，其目的在于：相邻两个齿21的长边相对布置，雾滴在甩出离心雾化盘1后能够撞击于齿21上，以实现精确雾化。
间距3为2毫米，若间距3太小，从离心雾化盘1甩出的雾滴无法完全撕裂，达不到撕裂效果；若间距3太大，雾滴失去动力，无法实现撞击进一步雾化。
齿21的长度为3毫米，如果齿21长度太短，设计齿21时会过密导致黏连，若齿21长度太长，多个雾滴同时碰到一个齿21上时，齿21表面会形成液膜，导致下一个雾滴被液膜吸收，无法实现撞击雾化。
相邻齿21之间的周向距离大于4毫米，作用在于防止齿21上的表面张力产生液膜，从而导致雾滴积聚在齿21表面。
齿21的径向横截面为矩形结构。离心雾化盘的直径为200毫米。离心雾化盘的转速为20000转/分。
为了配合使得雾滴撞击于齿21上的入射角都为45°左右，齿21的角度设计优选为0°，入射角为45°，有利于提高雾滴的撞击效果，使得雾化颗粒更加均匀。
齿21的根部与环状体2之间设置有倒角，使得齿21与环状体2之间的连接更加稳固
环状体2外涂布有电镀聚四氟乙烯层或纳米层，以此实现不粘效果，防止雾滴积聚于环状体表面。
导流槽11为阿基米德曲线状，提高离心雾化效果。
齿与导流槽的数量比为0.5：1～2：1，可选的，齿21与导流槽11按照比例0.8:1或1.5:1布置，只要能够实现每条导流槽11甩出的雾滴均能够在两个相邻齿21之间实现撞击即可。
离心雾化盘1围绕其轴心旋转时，环状体2相对于其轴心固定，或者，环状体2与离心雾化盘1的旋转方向相反布置，此时，环状体2的旋转方向与离心雾化盘1的方向相反，当离心雾化盘1与环状体2转向相逆设置时，提高了空气流动速度，相当于提高了离心雾化盘1的相对转速，进一步提高雾化效果。
本公开通过在离心雾化盘1外围增设一环状体2，环状体2上对应于导流槽11设置有齿21，雾滴在甩出离心雾化盘1之后撞击到齿21上，通过本公开的结构设计，对环状体2上的齿21进行精细设计，可以保证从离心雾化盘1出来的雾滴能更有效地在相邻两个齿21之间实现撞击，一方面，撞击角度更好，另一方面，齿21与导流槽11的数量设计，以及齿21的尺寸设计，防止产生液膜等而使雾滴积聚于齿21上，可以达到更好的雾化效果，提高了雾化颗粒的均匀度，同时，撞击减小了雾滴的平均粒径，能够达到30微米平均粒径的雾化效果，甚至10微米以下平均粒径的雾化效果，通过撞击，使得雾化更为充分，雾化颗粒更加均匀，浇灌喷洒更为均匀更易穿透，同时有效节约药液用量。
参见附图3所示，相邻两个齿21的根部之间通过弧形过渡，防止雾滴积聚于齿的根部，其余与上述实施例相同，这里不再赘述。
参见附图4～6所示，所述齿21的径向横截面为梯形，以此实现最大面积的碰撞，防止雾滴因为碰撞到短边而返回，其余与上述实施例相同，这里不再赘述。
为了简要描述，本实施例未提及之处，可参照上述实施例。进一步优选的方式，请参阅图7及 图8，本实施例提供的离心雾化装置包括了上述实施例中所述的离心雾化结构，上述实施例所描述的技术方案也属于该实施例；而且上述实施例所述的离心雾化盘1也属于本实施例提供的离心雾化盘1。
本公开实施例提供一种离心雾化装置，设于一喷洒设备(手持喷洒设备或喷洒无人机等)上(未给出图示)，所述离心雾化装置包括离心雾化盘1，离心雾化盘1上开设有多条导流槽11，各导流槽11由离心雾化盘1中央位置向边缘延伸。
离心雾化盘1外侧设置有一环状体2，该环状体2与所述离心雾化盘1同轴且相对转动设置，其中，离心雾化盘1相对于所述喷洒设备的主体转动设置，离心雾化盘1由电机驱动旋转，环状体2相对喷洒设备的主体固定设置，且该环状体2与离心雾化盘1之间在其径向上具有一间距3。
环状体2内沿其周向开设有一圈导气槽，环状体2的内周面上开设有多个气孔23，气孔23与导气槽连通，各气孔23在环状体2的周向上均匀间隔分布，气孔23出气口的气流方向与离心雾化盘1上导流槽11中甩出的液滴运行方向相反，以此在离心雾化盘1外围产生一个与离心雾化盘1自身反向的风场，提高了离心雾化盘1相对于空气气流的的相对转速。
液滴从离心雾化盘1边缘甩出时具有相对于静止空气的第一速度v1，正向风场的方向与离心雾化盘1的旋转方向相同，正向风场具有第二速度v2，其相对减小了液滴与空气的相对速度，使得液滴与空气的相对速度为v1-v2，而反向风场的方向与正向风场方向相反，并具有第三速度v3，大幅度提高了液滴与空气的相对速度，使得液滴与空气的相对速度为v1-v2+v3，反向风场对正向风场起到减弱或者逆转作用，使得空气流动速度增加，即液滴切割速度增加，雾化的液滴粒径减小。液滴与空气相对速度提高，即间接等于离心雾化盘相对于空气的相对转速提高。利用本公开实施例的离心雾化装置，可以实现1～30微米的液滴粒径，其平均粒径可以达到10微米左右，有效减小了液滴的平均粒径，极大地提高了雾化效果。同时，气流带的气流方向与导流槽中甩出的液滴的运行方向相反，以此，可以更好地实现液滴的切割，提高液滴与空气的相对速度，提高液滴的雾化效果。此处的气流带的气流方向和液滴的运行方向相反，可以理解为其两者方向的之间的夹角大于90°，优选地，在180°情况下，效果更佳。
优选地，反向风场的强度大于所述正向风场的强度，使得加速风场带的方向与反向风场相同，此时，实现的加速风场带，更大程度的提高了液滴与空气的相对速度，使得雾化效果倍增。在其他情况下，反向风场的强度也可以等于或者小于正向风场的强度，此时，加速风场带虽然没有实现方向上的逆转，但是仍然减弱了正向风场，提高了液滴与空气的相对速度，雾化效果仍然比较理想。
在垂直于离心雾化盘1轴线的气孔的轴向截面上，气孔23的轴线与离心雾化盘1上过该轴向截面上孔壁投影线中心的半径之间的夹角为60～75°。从离心雾化盘甩出的液滴相对于其切线方向具有一定的角度，将气孔的方向如此设计，可以使得从气孔中喷出的气体与液滴的方向呈180°相反设置，更好的实现切割液滴的作用，雾化效果更佳。
导气槽与一气泵的出气口连通，通过气泵向导气槽中充气。气孔出气口的孔径为1～3毫米，如果孔径太大，则气体压强过小，使得反向风场的风速过小，无法到达提高液滴相对速度的目的。气孔与导流槽的数量比为1：1～2：1，气孔数量过少，会导致风场带的风速相对减小，则无法到达提高液滴相对速度的目的。
环状体2与离心雾化盘1之间在其径向上的间距3为1～20毫米，优选为5～15毫米，若间距3太小，则无法产生加速风场带；若间距3太大，则加速风场带无法实现其提高液滴相对速度的作用。
离心雾化盘1的直径为50～300毫米。导流槽11为阿基米德曲线状，以提高液滴从离心雾化盘甩出的速度，提高离心雾化效果。离心雾化盘1的转速为2000～50000转/分，优选为10000～50000转/分。
在工作状态下，离心雾化盘1转动将液滴从导流槽11中甩出，环状体2上的气孔23沿其轴向朝向离心雾化盘1喷气，喷气产生的气流使得在环状体2和离心雾化盘1之间产生反向风场，其减弱或者逆转了离心雾化盘1自身的正向风场，以此在离心雾化盘1和环状体2之间提供了一个加速风场带，加速风场带提高了液滴与空气的相对速度，同时，气孔23内产生的高压气流的方向与导流槽11甩出的液滴方向相反，从而进一步撕裂液滴，使得雾化效果更好。当提高高压气流的流 速，则可以直接控制加速风场带的风场方向，实现与正向风场减弱或者相逆的加速风场带，灵活地提高液滴的相对速度，此时，无需提高离心雾化盘1的转速，就可以大大减小液滴的粒径大小，简单方便，容易实现。
请参阅图9所示，本公开实施例进一步提供一种离心雾化装置，设置于一喷洒设备(手持喷洒设备或喷洒无人机等)上(未给出图示)，包括离心雾化盘1，离心雾化盘1上开设有多条导流槽11，各导流槽11由离心雾化盘1中央位置向边缘延伸。
离心雾化盘1外侧设置有一环状体2，离心雾化盘1相对于喷洒设备的主体转动设置，环状体2也相对于喷洒设备的主体转动设置，离心雾化盘1与环状体2分别由其对应的电机驱动旋转，该环状体2与所述离心雾化盘1同轴且相对反向转动设置，且该环状体2与离心雾化盘1之间在其径向上具有一间距3；离心雾化盘1旋转在其周围形成一正向风场，该正向风场绕离心雾化盘1的中心顺时针或逆时针旋转；在工作状态下，环状体2在其与离心雾化盘1之间提供一反向风场，该反向风场的旋转方向与正向风场的旋转方向相反；反向风场和正向风场相互作用，在离心雾化盘与环状体之间形成一加速风场带环状体2上沿其周向间隔设置有多个齿21，各齿21以环状体2中心为基准向外呈放射状布置，环状体2旋转时，齿21靠近离心雾化盘1的一侧带动其附近的空气流动，以此产生气流带，多个气流带形成了反向风场，该反向风场减弱或者逆转了离心雾化盘1自身的正向风场，故可以提高液滴相对于空气的相对速度，提高雾化效果。气流带的方向与从离心雾化盘1甩出的液滴的方向相反，可以更有效对液滴进行切割，进一步提高雾化效果。
齿21在环状体2的周向上间隔且均匀分布。齿21的径向截面为矩形或弧形；当齿21的径向截面为矩形时，离心雾化盘1上过矩形长边中点的半径与该长边之间的夹角为0～60°；当齿21的径向截面为弧形时，离心雾化盘1上过弧形中点的半径与过弧形中点的切线之间的夹角为0～60°。
液滴在经过气流带的作用之后，撞击于齿21上，从相邻的齿之间发散出去，如此，经过撞击之后的液滴的粒径更小更均匀，雾化效果更好。齿21的夹角设计，可以使得撞击的效果更好，进一步的，可以实现45°最佳入射角撞击，雾化效果更佳。
相邻两个齿21之间的周向距离大于2毫米，优选大于3毫米，优选大于4毫米，作用在于防止齿21上的表面张力产生液膜，从而导致液滴积聚在齿21表面。
齿21在其放射方向上的尺寸为2～4毫米，在其轴向上的尺寸大于3毫米，垂直于放射方向的尺寸为0.5～1毫米；如果齿21在其放射方向上的尺寸太短，设计齿21时会过密导致黏连，若齿21在其放射方向上的尺寸太长，多个液滴同时碰到一个齿21上时，齿21表面会形成液膜，导致下一个液滴被液膜吸收，无法实现撞击雾化；当所述齿21的径向截面为弧形时，该弧对应的弦长即为该齿在放射方向上的尺寸。
环状体2及齿21上涂布有电镀聚四氟乙烯层或纳米层，使得环状体2及齿21上具有不沾效果，防止液滴积聚，提高雾化效果。
齿21与导流槽11的数量比为0.5：1～2：1，优选为1：1～1.8：1。
环状体2与离心雾化盘1之间在其径向上的间距3为1～20毫米，优选为3～10毫米，若间距3太小，则无法产生加速风场带；若间距3太大，则加速风场带无法实现其提高液滴相对速度的作用，同时，也无法实现进一步撞击的效果。
离心雾化盘1的直径为50～300毫米。导流槽11为阿基米德曲线状。离心雾化盘1的转速为2000～50000转/分，优选为10000～50000转/分，环状体2的转速为2000～50000转/分，优选为10000～50000转/分，通过提高环状体2的转速，可以实现加速风场带的方向的改变，随着环状体2转速的增加，加速风场带可以从与正向风场相同的旋转方向转变为与正向风场相反的旋转方向，即可以直接灵活控制环状体2的转速，提高液滴相对空气的相对速度，从而减小液滴的雾化粒径大小，本实施例中，只要选择环状体2的转速，就可以控制液滴的雾化粒径大小，简单方便，无需提高离心雾化盘的转速，避免因为离心雾化盘的转速太高而震碎，容易实现。
在工作状态下，液滴在甩出离心雾化盘之后经过加速风场带的作用，提高了液滴相对空气的相对速度，提高了雾化效果，同时，液滴撞击到齿21上，实现精准的撞击，进一步雾化，提高了雾化颗粒的均匀度，减小液滴的平均粒径，能够达到30微米平均粒径的雾化效果，甚至10微米以下平均粒径的雾化效果。在一个具体的实施例中，离心雾化盘1的转速为25000转/分，环状体2 的转速为18000转/分，离心雾化盘1的直径为100毫米，间距3为7毫米，此时，可以实现液滴平均粒径为10微米以下的雾化效果，显著提高了喷洒效果，这是现有技术难以达到的。
为了简要描述，本实施例未提及之处，可参照上述实施例。
进一步优选的方式，请参阅图10至图14，本实施例提供的驱动装置属于上述实施例中所述的喷洒设备，上述实施例所描述的技术方案也属于该实施例。为了解决现有中的驱动装置结构不稳定、转动惯量小的问题中的至少一个，本公开提供了一种驱动装置100，参见图10、图11和图13所示，包括第一驱动电机10，其包括一伸出第一驱动电机机身预设长度的第一输出轴101，以及第二驱动电机20，其包括一中空设置的第二输出轴201，其中，第一驱动电机10和第二驱动电机20同轴串连设置，第一输出轴101贯穿第二输出轴201并伸出第二输出轴。通过两个驱动电机的串连设置，并且将第一输出轴101套设于第二输出轴201中，以此减小第一输出轴101和第二输出轴201的直径，减小转动惯量，增加驱动装置的转速；以此实现高转速的喷洒装置。
需要说明的是，定义驱动装置100横截面圆心的连线方向为轴线方向，定义驱动装置100横截面圆的直径方向为径向。此处将第一驱动电机10和第二驱动电机20同轴串连设置，即第一驱动电机10沿着轴线方向同轴叠加设置于第二驱动电机20上，两者之间仅仅通过沿着轴线方向的第一输出轴101穿过沿着轴线方向的第二输出轴201，如此设计，可以尽可能减小第一输出轴101和第二输出轴201的直径，其直径越小，则驱动电机的转动惯量越小，高速旋转时越稳定。第一输出轴101的预设长度大于第二驱动电机的长度，根据第二驱动电机20的长度、以及需要夹持的转盘等因素而改变，此处不作限制。
驱动装置100还包括同轴设置于第二输出轴201末端的的连接件4和固持件5，连接件4一端套设于第二输出轴201上与其固定，另一端填充套设于第一输出轴101上的固持件5，以支承和稳定第一输出轴101和第二输出轴201。需要说明的是，第二输出轴201的末端为第一输出轴101伸出的一端，具体的，如图10所示，连接件4为中空圆柱状，第二输出轴201的末端深入其一端连接固定，优选地，连接方式为过盈连接，即第二输出轴201末端的最大外径大于与其配合的连接件一端的最大内径，通过外力使的连接件4紧密地套设于第二输出轴201上，结构简单，装配方便，当然，第二输出轴201和连接件4的连接方式不限于此，还可以是螺栓连接、铆接等等。通过将连接件4和固持件5设置于第二输出轴201上伸出第一输出轴101的一端，可以在最长距离上支承两个输出轴，防止由于第一输出轴101或第二输出轴201长度过长而造成末端结构不稳定，造成相互接触或摩擦而影响转动，最大程度上保证了两个驱动电机输出轴的稳定性，提高了转动效果。
可选地，驱动装置100还包括一壳体30，其套设于第一驱动电机10和第二驱动电机20外侧以固定第一驱动电机10和第二驱动电机20。将第一驱动电机10和第二驱动电机20同时设置于一个壳体30内，结构合理，装置稳定，并且便于安装。
本公开实施例通过将第一输出轴和第二输出轴串连设置并将第一输出轴套设于第二输出轴中，减小转动惯量，提高转速，实现20000转/分以上的高转速；两个驱动电机串连设置于同一壳体30中，使得两个输出轴之间的位置关系稳固，避免摩擦；通过连接件和固持件的配合，使得两个输出轴之间的位置更稳定，减小了摩擦对转动的影响。
为了简要描述，本实施例未提及之处，可参照上述实施例。
进一步优选的方式，请参阅图10及图15、图16、图17、图18及图19，本实施例提供的双驱动喷洒装置属于上述实施例中所述的喷洒设备，上述实施例所描述的技术方案也属于该实施例。且本实施例提供的双驱动喷洒装置包括上述实施例提供的驱动装置。
为了解决现有技术中的双驱动喷洒装置转动惯量大、结构不稳定的问题中至少一个问题，本公开提供了一种双驱动喷洒装置200，参见图10、图16、图17所示，双驱动喷洒装置200包括上述实施例提供的驱动装置以及第一转盘14，套设于第一输出轴101上并与其固定连接；第二转盘24，套设于第二输出轴201上并与其固定连接。可选地，第一转盘14中央位置设有第一定位孔141，第一输出轴101穿过第一定位孔141，第一定位孔141的形状与第一输出轴101横截面的形状互补，使得第一输出轴101穿过第一定位孔141并与其牢牢固定，此处，固定方法不作限制，可以通过螺栓连接、紧固件连接等等，优选地，设计第一输出轴的最大外径大于第一定位孔的的孔直径，使得第一输出轴与第一定位孔过盈配合以固定，结构简单，安装方便。可选地，第二转盘 24中央位置设有第二定位孔241，第二输出轴201穿过第二定位孔241，第二定位孔241的形状与第二输出轴201横截面的形状互补，使得第二输出轴201穿过第二定位孔241并与其牢牢固定，此处，固定方法不作限制，可以通过螺栓连接、紧固件连接等等，优选地，设计第二输出轴的最大外径大于第二定位孔的的孔直径，使得第二输出轴与第二定位孔过盈配合以固定，结构简单，安装方便。
双驱动喷洒装置200还包括同轴设置于第二输出轴201末端的连接件4和固持件5，连接件4一端套设于第二输出轴201上与其固定，另一端填充套设于第一输出轴101上的固持件5，以支承和稳定第一输出轴101和第二输出轴201。需要说明的是，第二输出轴201的末端为第一输出轴101伸出的一端。具体如图15所示，连接件4设置于第二转盘24和第一转盘14之间并固定于第二输出轴201的末端，而固持件5套设于第一输出轴101上，并且填充于连接件4内部，对第一输出轴101和第二输出轴201起到支承作用，防止两者相互碰撞摩擦。该双驱动喷洒装置200通过同轴共心设置两个驱动电机，可以在同侧设置两个电机带动两个转盘转动，同时配合连接件和固持件的作用，可以减小转动惯量，使得两个驱动电机的结构更稳固，转动更安全有效，实现更稳定、更高效的喷洒作业。
可选地，第二转盘24套设于连接件4上与第二输出轴201固定连接。如图17所示，第二定位孔241通过连接件4与第二输出轴201固定连接。与图15实施例区别在于：将连接件4设置于第二输出轴201和第二转盘24之间，通过与连接件4横截面形状互补配合的第二定位孔241使得第二转盘24与连接件4固定连接，由于连接件4本身与第二输出轴201固定连接，即第二输出轴201、连接件4、第二转盘24三者连接固定，大大节省了连接件4的安装空间，避免第一转盘14和第二转盘24之间的距离过大。此处连接方法不作限制，可以是螺栓连接、过盈连接、注塑连接等等。
可选地，连接件4包括一中空凸起的配合部41，配合部41形成一填充腔42以填充固持件5，第二转盘24套设于配合部41上。此处，第二定位孔241与连接件4一端的配合部41连接固定，无需与整个连接件4固定，减少第二转盘24的结构设计，同时可以巧妙填充固持件5，进一步节省了连接件4和固持件5的安装空间。
优选地，配合部41上沿周向设有一凸缘43，可以增加与第二转盘24之间的接触面积，固定防滑脱效果更好，增加第二转盘24与连接件4固定连接的强度，提高安全性和稳定性。
可选地，第一转盘14套设于第一输出轴101的末端，第二转盘24与第一转盘14在轴线方向上具有一轴向间距。需要说明的是，第一输出轴101的末端是竖直放置双驱动喷洒装置200时的最下端，也是双驱动喷洒装置200与作业对象距离最近的一端。在轴线方向上，第二转盘24与第一转盘14的轴向间距保证了两个转盘不会相互碰触而影响转动、喷洒效果，对轴向间距不作限制，本领域技术人员可以根据需要进行设计。具体的，第一输出轴101、第二输出轴201、第一定位孔141、第二定位孔241同轴设计，第一输出轴101从第二输出轴201的一端延伸出一定长度，第一输出轴101、第二输出轴201的转动分别带动第一转盘14和第二转盘24在不同的水平面上同轴运动，互不干扰，并且可以达到很高的转速。此处延伸的长度不作限制，与第二转盘24与第一转盘14的轴向间距有关，本领域技术人员还可以根据转盘的大小、雾化效果的影响因素而进行设计，只要保证与第一输出轴101连接的第一转盘14和与第二输出轴201连接的第二转盘24互不干扰且不影响雾化效果即可。
具体地喷洒方法为：参考图18所示，在第二转盘24上设有多个离心流道242，在第二输出轴201的带动下，高速旋转的第二转盘24对进入的药液进行离心作用雾化形成微小的雾滴，第二转盘24上还设有一盖板，防止雾滴飞溅；在盖板上设置一进水口，使得液体能够从进水口进入第二转盘24，当然，在一些情况下，也可以不设盖板，直接将液体输入到第二转盘24上；第一转盘14与第二转盘24同轴设置，其一径向侧面沿周向设置有多个齿142，齿142与第二转盘24的轴向侧边具有一径向间距。如此设计，使得第一转盘14延伸出第二转盘24的外侧，第一转盘14的齿延伸出第二转盘2外侧。装配状态下，齿142从第二转盘24的轴向侧面延伸出，并且齿142的上端面的高度大于或者等于第二转盘24的水平高度，以此对从第二转盘24上甩出的雾滴进行全方面的二次雾化，保证对尽量多的雾滴进行二次雾化，在一种实施例中，也可以设置齿142的上端面的高度小于第二转盘24的水平高度，此时在第二转盘24上方设置一个风力装置，在风力装置的作 用下，雾滴具有一个向下的趋势，无需加高齿142的高度也可以实现全面的二次雾化。在第一输出轴101的带动下，高速旋转的齿142对雾滴实现碰撞达到二次雾化的目的，可以减小雾滴的粒径以及提高雾滴的均匀性，可以形成30微米以下的雾滴的效果。径向间距与第一转盘14的转速、第二转盘24的转速、齿的大小、齿的密度、雾滴需要达到的粒径大小等等有关，此处不作限制。同时，考虑齿142的高度与第二转盘24之间的水平高度的关系，设计第一转盘14和第二转盘24时，其轴向间距也不能过大，否则会造成齿142的结构过高而影响转速。
可选地，如图16所示，固持件5包括一内环51与第一输出轴101固定连接，一外环52与连接件4固定连接，以及一滚动体53设置于内环51和外环52之间形成滚动摩擦。具体的，固定件5包括内环51、外环52、滚动体53、保持架54，其内环51随着第一输出轴101的转动而转动，外环52随着第二输出轴201的转动而转动，内环51和外环52通过多个滚动体53形成了滚动摩擦转动，保持架54保持多个滚动体在内环51和外环52中分布均匀，如此，使得固持件5和连接件4配合起到了支承第一输出轴101和第二输出轴201、降低摩擦系数、减少阻力的作用，避免两个输出轴接触产生摩擦。需要说明的是，图10中所示的固持件5的结构与图15和图17中相同，此处仅仅是省略了具体结构。
需要说明的是，第一输出轴101从第二输出轴201中穿出紧接着穿过固持件5，连接件4同时套设于第二输出轴201和固持件5上，并与两者紧固连接，连接件5外侧套设有第二转盘24，并与其紧固连接，在第二输出轴201旋转时，带动连接件5、第二转盘24以及固持件5上的外环以相同的转速和方向来旋转。而从固持件5中穿出的第一输出轴101，其自上而下依次套设有固持件5的内环以及第一转盘11，在第一输出轴101旋转时，带动第一转盘11和固持件5的内环以相同的转速和方向旋转。固持件5起到了支撑和稳定的作用，防止第一输出轴101和第二输出轴201的摩擦。
优选地，连接件4包括一中空凸起的配合部41，如图15、图16和图18所示，该配合部41形成一填充腔42以填充固持件5。具体的，连接件4为一中空阶梯圆柱状，在其一端设有一中空直径大于另一端的配合部41，配合部41和固持件5配合以容纳固持件5，如此，可以使得配合部41更容易收纳固持部5，便于装配，也便于检验是否安装合适，同时，也避免了增加第二输出轴201侧壁的径向宽度或者减小固持部5的最大外径，这两者都是不可取的，固持部5具有一定的尺寸，如果尺寸过小，无法实现支承作用，配合部41的设置，可以避免增大第二输出轴201的侧壁的径向宽度来配合容纳固持部5，防止由于第二输出轴201的径向宽度越大，转动惯量也变大，无法实现高速旋转。配合部41的设计，不仅便于固持件5的装配，防止第二输出轴201的直径过大而增大转动惯量，将配合部41设置于第二输出轴201和第二转盘24之间，还可以减小第二转盘24的结构设计，节约了连接件4和固持件5的整体安装空间，起到了一举多得的作用。
对于双驱动喷洒装置200，可选地，第一输出轴101的直径≤8mm，第二输出轴201的中空直径≤12mm，第二输出轴201侧壁的径向宽度d≤5mm。其中，侧壁径向宽度为在第二输出轴201的径向上，侧壁的厚度。进一步地，可以将第一输出轴101和第二输出轴201设计得更小，比如第一输出轴101的直径为5mm，第二输出轴201的中空直径为6mm，侧壁的径向宽度d为1mm，或者第一输出轴101的直径为4mm，第二输出轴201的中空直径为5mm，侧面径向宽度d为2mm等等，本领域技术人员可以根据结构需要对第一输出轴101和第二输出轴201的尺寸进行设计，对其大小不作限制。优选地，将第一输出轴101的直径、第二输出轴201的中空直径和侧壁径向宽度d设计得越小，则转动惯量越小，越可以实现高速旋转。
可选地，第一输出轴101和第二输出轴201配合具有一径向间隙，该径向间隙a≥0.1mm和/或≤1mm，第一输出轴101为圆柱状，第二输出轴201为中空圆柱状，两者之间配合贯穿设置。一种情况下，为了防止第一输出轴101与第二输出轴201接触而产生摩擦，影响电机的输出，无法实现高转速，故其径向间隙a不能过小，需要≥0.1mm；另一种情况下，其径向间隙a也不能过大，防止第一输出轴101与第二输出轴201间隙过大造成第二输出轴201直径也过大而增大转动惯量，无法实现高转速旋转，故径向间隙a≤1mm。径向间隙a可以同时满足≥0.1mm和≤1mm，也可以单独满足≥0.1mm或≤1mm中的任一条件，此处不作限制。
可选地，第一驱动电机10包括设置于内圈带动第一输出轴101转动的第一转子13以及设置于外圈的第一定子12，第二驱动电机20包括设置于内圈带动第二输出轴201转动的第二转23子以 及设置于外圈的第二定子202，第一定子12和第二定子202分别与一套设于第一驱动电机10和第二驱动电机20外侧的壳体30固定连接。具体的，壳体30套设于第一驱动电机10和第二驱动电机20外侧，通过第一定子12和第二定子202将第一驱动电机10和第二驱动电机20与壳体30固定，结构合理，装置稳定，并且便于安装。此处，第一定子12和第二定子202分别与壳体30的连接方式不作限制，可以包括过盈连接、螺钉连接、卡扣连接、黏胶连接等等，只要能够保证第一驱动电机10和第二驱动电机20分别与壳体30连接的牢固度即可。第一转子13带动第一输出轴101转动，第二转子203带动第二输出轴201转动，而第一定子12和第二定子202分别与壳体30固定，如此，两个驱动电机之间无需设置多余的稳定部件，就可以保证第一输出轴101和第二输出轴201的位置关系，防止两者接触摩擦而影响旋转。需要说明的是，第一驱动电机10和第二驱动电机20可以是有刷电机，也可以是无刷电机。
优选地，在第二输出轴201贯穿所述第二驱动电机的两端分别套设有一轴承6，在第一输出轴101靠近所述第二驱动电机一端也套设有一轴承6。参考图17所示，在第一输出轴101上套设有一轴承6，在第二输出轴201上套设两个轴承，以此起到支撑和稳定第一输出轴101和第二输出轴201的作用。三个轴承6，配合设置于第二输出轴201末端的连接件4和固持件5，就可以使得第一输出轴101和第二输出轴201可以稳定地运行而不会相互碰撞摩擦，不管第一输出轴101的长度有多长，也不会造成转动不稳定而影响旋转控制。在另一种实施例中，如图10和图15所示，也可以在第一输出轴101远离第二驱动电机的一端套设有轴承6，如此，在第一转子13的两侧都设有轴承6，可以保证第一输出轴的稳定性，当然，增加了一个轴承，会增加成本和重量。
优选地，分别在轴承6和第一转子13以及轴承6和第二转子203之间设有轴套7，避免第一转子13和第二转子203在转动过程中上下窜动，影响旋转。
可选地，在第二驱动电机20靠近连接件4一端设有一端盖，在端盖中央位置设有一密封件8，密封件8套设于第二输出轴201上，以实现防尘、防水的目的。端盖与壳体30密封连接，以使得第一驱动电机10和第二驱动电机20收容于其中。
以下举例说明双驱动喷洒装置200的工作过程：第二驱动电机20驱动第二输出轴201以顺时针旋转从而带动第二转盘24也以顺时针旋转，第一驱动电机10驱动第一输出轴21以逆时针旋转从而带动第一转盘14以逆时针旋转，旋转速度均可以达到20000转/分以上。药液注入第二转盘24，第二转盘24上设有多个离心流道242，药液在高速旋转的离心流道242的作用下撕裂形成微小的雾滴，同时第一转盘14上设有多个的齿142，高速旋转的齿142对雾滴起到了二次雾化的作用，使得雾滴的颗粒更小、更均匀，实现30微米以下的雾化效果。需要说明的是，第一输出轴和第二输出轴的旋转方向不作限制，可以是相同的方向，也可以是相逆的方向；可以是顺时针旋转，也可以是逆时针旋转，本领域技术人员可以根据需要来控制第一驱动电机和第二驱动电机的转向。
本公开通过将第一输出轴和第二输出轴串连设置并将第一输出轴套设于第二输出轴中，减小转动惯量，提高转速，实现20000转/分以上的高转速；两个驱动电机串连设置于同一壳体30中，使得两个输出轴之间的位置关系稳固，避免摩擦；通过连接件和固持件的配合，使得两个输出轴之间的位置更稳定，减小了摩擦对转动的影响；将连接件和固持件设置于第二输出轴和第二转盘之间，大大节省了连接件和固持件的安装空间，同时结构简单，安装方便，又保证第二输出轴和第二转盘连接的牢固性。
上述实施例仅供说明本公开之用，而并非是对本公开的限制，有关技术领域的普通技术人员，在不脱离本公开范围的情况下，还可以做出各种变化和变型，因此，所有等同的技术方案也应属于本公开公开的范畴。
工业实用性
本公开实施例提供的离心雾化结构，能够提高了雾化颗粒的均匀度，通过撞击，使得雾化更为充分，雾化颗粒更加均匀，浇灌喷洒更为均匀更易穿透，同时有效节约药液用量。
