具体地，接尘盘133朝向排尘口220的表面为内凹形弧面，集尘口134开设于内凹形弧面的最低点处，进而方便落入到接尘盘133内的灰尘有效落入到集尘口134内，避免灰尘在接尘盘133内堆积。
可选地，旋风分离器200通过支架300设置于接尘盘133上，支架300能够覆盖在接尘盘133上。由于旋风单元230插设于定位孔312内，进而能够有效对准接尘盘133。支架300覆盖在接尘盘133上使得接尘盘133与集尘腔110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，分隔部132设置于接尘盘133背向于集尘部131的一侧，接尘盘133朝向集尘部131的一侧还开设有入气口135，入气口135与进气腔120相连通。由于旋风分离器200设置于接尘盘133上，将分隔部132设置于接尘盘133上有利于分隔部132与进气管250的对接。同时，由于入气口135的开口朝向集尘部131的方向，使得带尘气体能 够由集尘部131的外周侧进入入气口135，并通过进气腔120进入到进气通道252，进而形成进气通路；而灰尘通过排尘口220落入接尘盘133，由集尘口134进一步落入集尘腔110内，形成集尘通路；通过分隔部132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。
具体地，入气口135与集尘口134分隔设置，进一步避免形成的集尘通路与进气通路的相互连通干扰。
一实施例中，分隔部132背向于进气管250的一端一体成型于接尘盘133上，能够有效提高分隔部132在接尘盘133上设置的稳定性，避免带尘气体由分隔部132与接尘盘133之间的间隙泄露。在其他实施例中，分隔部132背向于进气管250的一端还可以直接穿设于入气口135，使得带尘气体能够直接进入到进气腔120。
在本实施例中，接尘盘133一体成型于集尘部131上，进而能够提高灰尘由接尘盘133落入集尘腔110的稳定性，避免灰尘由接尘盘133与集尘部131之间的间隙泄露。
请再次参阅图2及图3，一实施例中，集尘组件100还包括过滤件140，过滤件140形成有过滤腔142，集尘部131背向于旋风分离器200的一端穿设于过滤腔142内，进气腔120与过滤腔142相连通。通过设置过滤件140能够有效过滤带尘气体中的大颗粒灰尘，形成一级过滤分离。经过过滤件140的带尘气体由进气腔120进入旋风分离器200中，能够进行二级气尘分离，能够有效提高气尘分离的效率。
一实施例中，集尘组件100还包括尘杯150，尘杯150上形成有容纳腔152，尘杯150上开设有与容纳腔152相连通的吸入口154，过滤件140设置于容纳腔152内。容纳腔152通过过滤件140与过滤腔142连通。带尘气体由尘杯150的吸入口154进入到容纳腔152内，经过过滤件140的过滤之后进入到过滤腔142内，使得大颗粒的灰尘有效留在容纳腔152内，进而有效实现灰尘的二级分离。
具体地，吸入口154的开口方向与容纳腔152的内壁相切，进而带尘气体进入到容纳腔152内后，能够沿着容纳腔152的内壁旋转，利用离心力和重力的作用，能够起到一定的分离效果，进而提高分离机构10的气尘分离效果。
进一步地，吸入口154开设于尘杯150的上部或靠近上部的位置，避免由吸入口154进入的带尘气体将容纳腔152底部的灰尘吹起，影响分离机构10的气尘分离效果。
上述实施例中的第一轴线a为尘杯150的中轴线；当然，第一轴线a还可以为集尘腔110的中轴线。具体地，尘杯150与集尘腔110可以同轴设置。
一实施例中的吸尘器包括上述任一实施例中的分离机构10。带尘气体通过过滤件140能够实现一级过滤，使得较大颗粒的灰尘留在尘杯150的容纳腔152内。带尘气体进一步 由集尘器130外周侧进入到分隔部132的进气腔120内，并通过支架300上的通气孔314进入到进气管250的进气通道252内。由进气通道252进入到旋风单元230内，实现二级分离。通过进气腔120与进气通道252的配合不仅能够有效提高进气的均匀性，同时还能够使得带尘气体稳定地通过进气通道252输送至旋风单元230的进气口210处，进一步提高进气的稳定性及均匀性。分离后的灰尘由旋风单元230的排尘口220排入接尘盘133，并通过集尘口134落入到集尘腔110内，实现灰尘的收集。上述吸尘器能够有效实现气尘分离效果，提高气尘分离效率。
以上所述实施例仅表达了本申请的几种实施例，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
