请参阅图1及图2，一实施例中的旋风分离机构10，能够有效实现气尘分离效果，且至少能够提高带尘气体流通的稳定性，降低流通风阻，降低噪音。具体地，旋风分离机构10包括集尘结构100及旋风分离器200。
请一并参阅图3，集尘结构100包括集尘部110及进气部120，集尘部110形成有集尘腔112，集尘部110上开设有与集尘腔112相连通的集尘口114；进气部120设置于集尘部110的一侧，进气部120形成有进气通道122，进气部120的一端开设有与进气通道122相连通的入气口124，另一端上开设有与进气通道122相连通的排气口126，排气口126与集尘口114分隔设置。旋风分离器200的一端开设有进气口210，另一端开设有与进气口210相连通的排尘口220，旋风分离器200设置于集尘结构100上，排尘口220通过集尘口114与集尘腔112相连通；旋风分离器200的进气口210通过排气口126与进气通道122相连通。
上述旋风分离机构10在使用时，由于进气部120的排气口126与集尘部110的集尘口114的分隔设置，将旋风分离器200设置于集尘结构100上，使得旋风分离器200一端的进气口210通过排气口126与进气部120的进气通道122相连通，旋风分离器200的另一端的排尘口220通过集尘口114与集尘腔112相连通。带尘气体能够由进气部120一端的入气口124进入到进气通道122内，通过进气部120另一端的排气口126排入到旋风分离器200的进气口210。带尘气体在旋风分离器200内进行气尘分离，分离后的灰尘由排尘口220通过集尘口114与集尘腔112，实现灰尘的收集。由于带尘气体通过进气通道122 进入到旋风分离器200内，进而通过进气通道122能够为带尘气体的流通提供有效的导向作用，降低了带尘气体在流通过程中的风阻，提高了带尘气体流通的稳定性，进而能够有效降低旋风分离机构10在使用过程中的噪音。
一实施例中，旋风分离器200包括多个旋风单元230及进气管240，进气管240形成进气腔242，多个旋风单元230围设于进气管240的外周侧，单个旋风单元230的一端开设有进气口210，另一端开设有排尘口220，每一旋风单元230的进气口210朝向进气腔242并与进气腔242相连通，进气部120的排气口126与进气腔242相连通。带尘气体由进气通道122进入到进气管240的进气腔242内，进而能够将带尘气体进一步进行聚拢，通过进气管240能够进一步提高对带尘气体的导向作用。由于旋风单元230的进气口210朝向进气腔242，进气腔242内的带尘气体能够有效分配到多个旋风单元230内，有效提高进入到每个旋风单元230内带尘气体分布的均匀性，进而提高气尘分离效率。
具体地，多个旋风单元230围绕进气管240的外周侧均匀分布，能够进一步提高进入每一旋风单元230内的带尘气体的均匀性，进一步提高气尘分离效率。
在本实施例中，多个旋风单元230一体成型于进气管240上，能够有效提高进气口210与进气腔242连通的稳定性，提高带尘气体分布的均匀性。在其他实施例中，多个旋风单元230围成环状结构，进气管240还可以插设于环状结构内。

一实施例中，旋风分离器200还包括排气组件250，旋风单元230的一端上还开设有出气口232，排气组件250上开设有与旋风单元230数量相对应的排气通道252，排气组件250设置旋风分离器200的一端上，每一排气通道252对应插设于一出气口232内。当灰尘由带尘气体中分离出来以后，通过排气组件250使得干净气体能够由对应的排气通道252排出。
具体地，排气组件250包括排气本体254及排气管256，排气管256形成排气通道252，排气本体254盖设于旋风分离器200的一端上，以使排气管256的一端穿过排气本体254并由出气口232穿设于旋风单元230内。通过形成排气管256穿设于旋风单元230内，能够避免带尘气体由进气口210进入旋风单元230内后，未经过分离直接由出气口232排出，提高气尘分离的稳定性。
请参阅图2及图3，一实施例中，进气部120至少为两个，至少两个进气部120围绕集尘部110的中轴线a设置。通过设置至少两个进气部120能够有效提高带尘气体进入不 同的进气通道122的均匀性，进而能够进一步提高带尘气体流通的稳定性，降低噪音，提高气尘分离效率。
具体地，至少两个进气部120围绕集尘部110的中轴线a均匀设置，能够进一步提高带尘气体进入不同的进气通道122的均匀性，更进一步提高带尘气体流通的稳定性，提高气尘分离效率。

请参阅图4，一实施例中，集尘部110朝向进气部120的外壁内凹设置形成凹槽116，凹槽116与入气口124相连通。通过在集尘部110的外壁形成凹槽116，使得带尘气体能够有效聚集在凹槽116内，并通过凹槽116有效通过入气口124进入到进气通道122内，提高带尘气体进入进气通道122内的效率。
具体地，凹槽116的底壁通过入气口124平滑过渡至进气通道122的内壁，能够有效降低带尘气体由凹槽116通过入气口124进入到进气通道122的稳定性，降低风阻，降低噪音的产生。
在本实施例中，集尘部110形成凹槽116的底壁的部分延伸形成进气部120的部分，该部分为凹槽116的底壁平滑过渡至进气通道122内壁的部分，实现进气部120与集尘部110的部分共壁设置。使得集尘结构100结构更紧凑，便于生产制造。当然，在其他实施例中，集尘部110与进气部120还可以不共壁设置。
请参阅图5，一实施例中，进气部120围绕集尘部110的中轴线a间隔设置，集尘口114包括至少两个入尘口113，至少两个入尘口113围绕集尘部110的中轴线a设置，每相邻两个进气部120之间设置有一入尘口113。通过在每相邻两个进气部120之间形成一入尘口113能够有效扩大集尘口114的尺寸，使得由排尘口220排出的灰尘有效通过集尘口114落入到集尘腔112内，提高集尘的效率。
具体地，集尘口114还包括连通口115，至少两个入尘口113围绕连通口115设置， 且入尘口113均与连通口115相连通。通过连通口115连通不同的入尘口113能够进一步提高集尘的效率及稳定性，使得灰尘有效落入到集尘腔112内。
请参阅图3至图5，一实施例中，集尘结构100包括接尘盘130，接尘盘130设置于集尘部110开设有集尘口114的一侧，集尘口114贯穿接尘盘130。通过设置接尘盘130能够有效扩大集尘面积，进一步提高集尘稳定性。
具体地，接尘盘130背向于集尘部110的表面为内凹形弧面，集尘口114位于内凹形弧面的最低点处，进而方便落入到接尘盘130内的灰尘有效落入到集尘口114内，避免灰尘在接尘盘130内堆积。
一实施例中，进气部120设置于接尘盘130背向于集尘部110的一侧，入气口124贯穿接尘盘130朝向集尘部110的一侧。将进气部120设置于接尘盘130上有利于进气部120与进气管240的对接。同时，由于入气口124的开口朝向集尘部110的方向，使得带尘气体能够由集尘部110的外周侧进入入气口124，并通过进气通道122进入到进气腔242，进而形成进气通路；而灰尘通过排尘口220落入接尘盘130，由集尘口114进一步落入集尘腔112内，形成集尘通路；通过进气部120能够有效分隔进气通路与集尘通路，避免进气通路与集尘通路相互干扰。
在本实施例中，接尘盘130一体成型于集尘部110上，能够提高灰尘由接尘盘130落入集尘腔112的稳定性，避免灰尘由接尘盘130与集尘部1101之间的间隙泄露。在其他实施例中，接尘盘130还可以通过焊接或胶结等等方式设置于集尘部110上。
在本实施例中，进气部120的一端一体成型于接尘盘130上，能够有效提高进气部120在接尘盘130上设置的稳定性，避免带尘气体由进气部120与接尘盘130之间的间隙泄露。在其他实施例中，进气部120还可以直接穿设于接尘盘130上，使得带尘气体能够直接由入气口124进入到进气腔242。

可选地，旋风分离器200通过支架300设置于接尘盘130上，支架300能够覆盖在接尘盘130上。使得接尘盘130与集尘腔112形成为封闭的集尘空间，避免灰尘由集尘空间飞出，提高集尘的稳定性。
一实施例中，安装平台310的数量与旋风分离器200的数量相对应，每一旋风分离器200对应设置于一安装平台310上，进而能够为每一旋风分离器200提供有效的安装支撑。
