具体实施方式
以下结合附图和具体实施例对本申请作具体的介绍。
参照图1和图2，本申请提供一种管道清洁机100，包括把手110、滚筒120、线缆130以及电机140，把手110供用户握持，滚筒120与把手110连接，且能相对把手110转动。线缆130设置于滚筒120内，电机140能驱动滚筒120和线缆130转动。电机140包括能绕第一轴线101转动的电机轴141，电机轴141和滚筒120固定连接，从而电机140带动滚筒120转动。线缆130被设置盘绕在滚筒120内，且被滚筒120支撑，线缆130能随着滚筒120转动。该管道清洁机100还包括送线组件150，用于进给线缆130，送线组件150设置于滚筒120的前端121，线缆130从滚筒120内伸入到送线组件150内，且能从送线组件150向前侧伸出，并从送线组件150向滚筒120内部回缩。
线缆130由弹性材料制作，从而线缆130能围绕在滚筒120内，且可在待清洁的管道内弯曲。线缆130可以是由弹簧钢丝制作，其前部设有钻头，用于清理管道内的杂物。线缆130的后端盘绕在滚筒120内，在送线组件150进给线缆130时，部分盘绕在滚筒120内的线缆130相对脱开被向前送出，在使用完毕该管道清洁机100时，用户通过操作电机140反转带动线缆130回到滚筒120内，线缆130再次盘绕在管道内。可选的，线缆130前部设有附件连接装置，用于安装其它附件如刀片、钳件。
送线组件150包括辅助把手110，以及在辅助把手110内形成的送给通道151，送给通道151轴向支撑线缆130，线缆130能在送给通道151内沿着第一轴线101的方向向前伸出和回缩，线缆130基本沿着第一轴线101在送给通道151内延伸。送线组件150还包括定滚轮152、动滚轮153以及操作件154，操作件154与动滚轮153连接，并能使得动滚轮153在远离或趋向第一轴线101的方向运动。定滚轮152设有两个，其在辅助把手110内的相对位置固定。操作件154能将动滚轮153移动到第一位置和第二位置，在动滚轮153位于第一位置时，动滚轮153相对远离第一轴线101，此时动滚轮153和线缆130不接触。在动滚轮153被移动到第二位置时，动滚轮153相对靠近第一轴线101，此时动滚轮153和线缆130接触，且动滚轮153和定滚轮152配合夹持线缆130。动滚轮153、定滚轮152相对于第一轴线101倾斜，由于线缆130为螺旋状，旋转的线缆130相对动滚轮153和定滚轮152转动，从而滚轮能将线缆130从送给通道151中送出或收回。可选的，操作件154可以是设置于辅助把手110上的扳机，在用户按压扳机使得动滚轮153位于第二位置时，扳机向辅助把手110内部内陷，使得扳机表面基本能和辅助把手110的表面对齐或两者间距在5mm之内。
滚筒120包括暴露于空气的露出部分，露出部分的表面积与滚筒120的总表面积的比值大于或等于40％且小于或等于100％。可选的，所述滚筒包括暴露于空气的露出部分，所述露出部分的表面积与所述滚筒的总表面积的比值大于 或等于20％且小于或等于100％。
参照图2和图3，可滚筒120包括靠近送线组件150的前端121、靠近把手110的后端123以及位于前端121和后端123之间的中部122。滚筒120内部生产容纳腔125，用于储存盘绕的线缆130。滚筒120还生成安装腔124，安装腔124生成于滚筒120的后部。在第一轴线101的径向方向上，安装腔124和容纳腔125的投影部分重叠。可选的，在第一轴线101的径向方向上，安装腔124的投影位于和容纳腔125的投影内，至少部分电机140被置入安装腔124内。安装腔124形成于滚筒120的中后部，滚筒120具有形成安装腔124的内壁。可选的，安装腔124是以第一轴线101为轴的回转体。安装腔124可以是柱体或圆台体。线缆130围绕在内壁周侧，从而至少部分电机140位于线缆130围成的空间内。部分电机140在第一轴线101的方向上，位于滚筒120的后端123的前方，从而滚筒120的后端123在第一轴线101径向方向的投影与电机140在该方向上的投影重叠。
管道清洁机100还包括传动机构160，传动机构160连接电机140和线缆130，传动机构160可以是行星齿轮组，用于对滚筒120减速。传动机构160与电机轴141连接，能被电机轴141驱动转动。传动机构160的输出端设有输出轴，输出轴和滚筒120固定连接，连接的方式可以是通过螺钉连接。电机140转动时，通过传动机构160带动滚筒120减速转动，滚筒120带动线缆130同步转动。传动机构160被设置在安装腔124内，进一步减小管道清洁机100的整机尺寸。
滚筒120包括暴露于空气的露出部分，从而滚筒120露出部分的表面积与滚筒120的总表面积的比值大于或等于40％且小于或等于100％，例如滚筒120露出部分的表面积与滚筒120的总表面积的比值大于或等于65％且小于或等于100％。部分滚筒120外侧不设有罩壳，使得管道清洁机100整机尺寸较小，以减轻其重量，使得管道清洁机100便于工作。可选的，至少部分的滚筒120的前端121和至少部分中部122暴露于空气中，即滚筒120的前端121和至少部分中部122外侧没有设置罩壳，仅在靠近把手110的后端123设置防护罩。
管道清洁机100还包括电机壳体142，电机壳体142包装并支撑电机140，电机140可在电机壳体142内部转动。电机壳体142和把手110固定连接，可选的，电机壳体142和把手110通过螺钉件固定连接，或是电机壳体142与把手110一体成型地模制而成。至少部分电机壳体142位于安装腔124内，电机壳体142的前部的形状和安装腔124的形状匹配。管道清洁机100还包括支撑件170a，设置于安装腔124内，且设置于电机壳体142的周向上。支撑件170a能接触滚筒120的内壁并支撑滚筒120。支撑件170a包括连接轴173和套接于 连接轴173的支撑轴承174，支撑轴承174能绕连接轴173转动，支撑轴承174和滚筒120的内壁直接或间接接触。通过支撑轴承174，滚筒120能相对电机壳体142转动，且能被电机壳体142支撑。支撑件170a和设置在输出轴上的螺钉配合共同支撑滚筒120，使得滚筒120能相对把手110和电机壳体142转动，但是在第一轴线101的轴向方向上与把手110位置相对固定。可选的，支撑件170a设有四个，均匀地分布在电机壳体142的周向上，以使得电机壳体142稳定支撑滚筒120。
参照图4，可选的，支撑件170a被设置在滚筒120后方。支撑件170a包括第一支撑件171和第二支撑件172，第一支撑件171设置于滚筒120的后端123，第二支撑件172设置于把手110或者电机壳体142内，第一支撑件171和第二支撑件172能相对转动。第一支撑件171和第二支撑件172为接触的环形凸筋或环形槽，从而第一支撑件171能嵌入第二支撑件172内，或第二支撑件172嵌入第一支撑件171，使得第一支撑件171能相对第二支撑件172转动。可选的，第一支撑件171为环形凹槽，第二支撑件172为环形凸筋，第二支撑件172被设置嵌入第一支撑件171，连接方式简单的同时，可以缩短管道清洁机100的整机长度。
管道清理装置还包括支座，设置于滚筒120下方，支座可以支撑管道清洁机100整机，使得管道清洁机100可以平稳的放在平面上。由于上述的管道清洁机100的整机设置，使得管道清洁机100的重心合理，管道清洁机100的重心向下的投影位于支架和滚筒120向下投影的重叠区域，使得整机可以通过支座稳定的站立在平面上。可选的，所述管道清理装置的重心向下的投影位于所述滚筒120向下的投影的中后部，从而减低用户使用管道清洁机100的疲劳感。支座一侧或把手下方设有电源结合部，可以连接电源组件或者形成电源线，当连接电源组件时，电源组件具有一个和支座底部平行的平面，该平面与支座底部共同构成放置整机的平面。
可选的，参照图5和图6，操作件154a为套接在辅助把手110上的环形件，操作件154a相对辅助把手110可以转动，操作件154a内设有凸起结构，在操作件154a相对辅助把手110转动到某一位置时，凸起结构能推动动滚轮153向第一轴线101靠近，从而使得动滚轮153移动到第二位置。可选的，辅助把手110上还设有锁定件190和锁定销191，锁定件190能带动锁定销191与滚筒120啮合和脱开，在锁定销191和滚筒120啮合时，滚筒120和辅助把手110能同步转动。在使用管道清洁机100时，将动滚轮153移动到第一位置，线缆130不会被送出，从而线缆130伸出辅助把手110的长度不变，通过锁定销191使得滚筒120和辅助把手110同步转动，防止线缆130过度弯扭，使得线缆130缠绕不能正常工作。可选的，管道清洁机100包括套筒，套筒套接在辅助把手外 侧，套筒相对辅助把手能转动，套筒供用户握持，此时辅助把手能相对套筒旋转。可选的，套筒和操作件154a为同一个环形件。
如图6所示，管道清洁机100高度记为H，该高度为滚筒顶端到支座或电源组件底端之间的垂直距离，H大于或等于200mm小于或等于350mm，尤其可以为大于或等于220mm小于或等于300mm。如图7所示，管道清洁机100宽度记为L1，由于整机中宽度占比较大的为滚筒120，且本实施例的滚筒120直接暴露在工作环境中，则在本实施例中，该宽度也可以认为是滚筒120直径。本实施例中L1大于或等于180mm小于或等于250mm，尤其可以为大于或等于190mm小于或等于230mm。管道清洁机100长度记为L2，该长度(不含线缆)为由送线组件150的远端到把手110或电源组件的远端之间的垂直距离，L2大于或等于430mm小于或等于550mm，尤其可以为大于或等于440mm小于或等于530mm。
如图8所示的管道清洁机100的另一实施例，送线组件150与滚筒120的连接处设有套筒轴承180。在上一实施例中，该处结构与套筒一体成型，形成一种具有凸边的筒形结构。在本实施例中，套筒轴承180一端与滚筒120端部连接，或套设在滚筒120端部外，另一端形成凸边与送线组件150连接，或者送线组件150套设在该另一端的外侧。套筒轴承180可给相对运动的滚筒120和送线组件150提供支撑，减小二者之间直接接触带来的摩擦。在本实施例中，支撑件可以与滚筒120壳体一体成型。
