 具体实施方式
下面结合附图和实施例对本公开作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅用于解释本公开，而非对本公开的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本公开相关的部分而非全部结构。
参见图1至图28所示的一种清洁设备，该清洁设备用于清洁待清洁面，尤其包括一些体积比较大，高度比较小，并且低于一般人手持高度的清洁设备，待清洁面主要是指地面。
参见图1至图3所示，该清洁设备包括机体10、设于机体10底部的行走轮1，该清洁设备还包括驱动装置2、离合装置3及设置在机体10上的推拉部件20，其中，切换装置3设置在驱动装置2与行走轮1之间，该切换装置3具有可切换的第一工作状态与第二工作状态，当切换装置3处于第一工作状态下，切换装置3与驱动装置2相互配合，使得驱动装置2与行走轮1之间传动地连接，行走轮1能够在驱动装置2的驱动作用下自动行进；当切换装置3处于第二工作状态下，切换装置3与驱动装置2脱离配合，驱动装置2脱离与行走轮1的传动连接，此时，操作人员可以通过推拉部件20来推拉该清洁设备行走，这样，一方面，在推拉该清洁设备行走的过程中，不需要克服来自驱动装置2的阻力，另一方面，也避免了驱动装置2内电机被反向上电的可能性，保证电机的使用寿命。
具体地，参见图4至图17所示，行走轮1包括轮体11与轮轴12，轮体11同轴地固设于轮轴12上。驱动装置2至少包括驱动件，该驱动件能够相对转动地套设在轮轴12上，切换装置3包括切换件31，该切换件31套设在轮轴12上且能够与轮轴12同步转动，切换件31与驱动件这两者中的一者上设置有凸出部，另一者上设置有容纳部。当切换装置3处于第一工作状态下，凸出部嵌设于容纳部中，使得切换件31与驱动件能够同步旋转，行走轮1能够被驱动装置2驱动；当切换装置3处于第二工作状态下，凸出部脱离容纳部，此时轮轴12能够相对驱动件转动，驱动装置2不再能够驱使行走轮1行进。本实施例中，驱动装置2包括电机21、主动轮22、从动轮23以及张紧于主动轮22与从动轮23之间的同步带，从动轮23同轴且转动套设在轮轴12上，电机21用于驱动主动轮22转动，从动轮23构成上述的驱动件。
通过凸出部与容纳部之间的嵌合或脱离，使得行走轮1在能够被驱动装置2驱动而自动行走与脱离由驱动装置2的驱动而能够被推拉行走这两种方式之间切换，结构合理，便于装配，而且切换装置3处于第二工作状态下，轮轴12与轮体11能够相对从动轮23转动，手动推动清洁设备的过程中，减少了来自电机21的阻力，降低了推动行走轮1所需要的推力，便于手动推动而驱使行走轮1行进，同时也避免了电机21的反向上电，保护了电机21，保证了电机21的使用寿命，从而保证了清洁设备整体的耐用性，降低了维护成本。此外，通过主动轮22、从动轮23以及同步带24的连接形式实现电机21驱动轮体11转动，也能够缩小沿轮轴12轴向的尺寸，利于减少占用的空间，增加了驱动装置2的结构紧凑程度，提高了驱动装置2的实用性。
在本实施例中，轮轴12为圆柱轴，轮体11包括轮胎111和轮毂112，轮胎111沿周向设置在轮毂112的侧壁上，轮毂112与轮轴12同轴连接。
如图8至图10所示，在本实施例中，切换件31呈环状。轮轴12包括同轴连接的第一轴段121以及第二轴段122。第二轴段122的横截面为圆形，从动轮23的内侧壁的横截面为圆形，实现从动轮23能够相对第二轴段122相对转动。第一轴段121包括同步连接轴段1211，同步连接轴段1211与第二轴段122同轴连接，切换件31套设于同步连接轴段1211时，切换装置3处于第一工作状态，切换件31能够与轮轴12同步转动。
如图8至图10所示，具体地，同步连接轴段1211的侧壁包括两个第一平面部，两个第一平面部平行且间隔设置，两个第一平面部之间连接有两个第一弧面部，第一平面部与第一弧面部交替设置，两个第一平面部对应的圆心角相同，同时，切换件31的内侧壁包括两个第二平面部3151，两个第二平面部3151平行且间隔设置，两个第二平面部3151之间连接有两个第二弧面部3152，第二平面部3151与第二弧面部3152交替设置，两个第二平面部3151对应的圆心角相同。第一弧面部的轴线与第二弧面部3152的轴线共线。切换件31处于同步连接轴段1211上时，两个第一平面部与两个第二平面部3151对应贴合，两个第一弧面部与两个第二弧面部3152相互贴合。
在其他实施例中，同步连接轴段1211的横截面也可呈D型，即同步连接轴段1211的侧壁包括一个第一平面部以及一个第一弧面部，此时，切换件31的内侧壁的横截面也呈D型，即切换件31的内侧壁包括一个第二平面部3151以及一个第二弧面部3152，当切换装置3处于第一工作状态时，切换件31处于同步连接轴段1211上，且第一平面部与第二平面部3151相互贴合，实现从动轮23能够带动切换件31和轮轴12同步转动。在其他未提及的实施例中，切换件31与同步连接轴段1211的横截面还可为其他形状，实现切换件31与轮轴12能够同步转动即可，在此不做限定。
具体地，凸出部与容纳部分设于从动轮23与切换件31这两者朝向彼此的端面上，切换件31与从动轮23这两者能够沿轮轴12的轴向相向移动，使得切换装置3在第一工作状态与第二工作状态之间切换。上述结构设置，使得切换件31与从动轮23之间沿轮轴12轴线的相对移动，实现切换装置3在第一工作状态与第二工作状态之间的切换，简化了切换过程，便于操作。本实施例中，切换件31能够沿轮轴12的轴向滑动地套设在轮轴12上，从动轮23在轮轴12上的轴向位置不变，结构更为简单。此处，从动轮23固定套设在第二轴段122上，切换件31滑动套设在第一轴段121上，即切换件31能够沿轮轴12的轴向移动。
如图8所示，第二轴段122上固定套设有两个挡圈14，从动轮23套设在第二轴段122上并夹设在两个挡圈14之间，防止从动轮23移动，从而使得切换装置3能够可靠地由第一工作状态切换至第二工作状态，进一步避免了在手动驱动行走轮1时由电机21产生的阻力，也避免了电机21的反向上电。
在其他实施例中，也可是将切换件31固定套设在第一轴段121上，从动轮23滑动套设在第二轴段122上，在此不作限定。
本实施例中，从动轮23与挡圈14之间还可设置有调节圈15，调节圈15套设在轮轴12上，若从动轮23与挡圈14之间存在缝隙，调节圈15能够填充在缝隙内，能够进一步避免从动轮23沿轴向移动。
本实施例中，第一轴段121还包括转动连接轴段1212，转动连接轴段1212与同步连接轴段1211同轴连接，同步连接轴段1211连接于转动连接轴段1212与第二轴段122之间，切换件31滑动套设在第一轴段121上，即切换件31能够沿轴向在转动连接轴段1212与同步连接轴段1211之间移动。转动连接轴段1212的横截面为圆形，转动连接轴段1212的直径不大于两个第二平面部3151之间的垂直距离，使得切换件31处于转动连接轴段1212上时，实现切换件31能够相对转动连接轴段1212转动。
本实施例中，切换件31与轮体11分别设置在从动轮23的相背两侧，切换装置3还包括握持件32，握持件32连接于切换件31相背于从动轮23的一端。设置握持件32，便于实现移动切换件31，从而提高了使用便利性。
参见图8所示，轮轴12还包括第三轴段123，轮体11同轴固定在第三轴段123上，第三轴段123同轴连接于第二轴段122远离第一轴段121的一端。
如图4至图8所示，轮轴12远离轮体11的一端固定有止挡件13，止挡件13包括连接部131以及凸出设置的止挡部132，连接部131连接于轮轴12，止挡部132凸设在连接部131的侧壁上并沿轮轴12的径向延伸；切换件31相背于从动轮23的端面上开设有容纳孔313，容纳孔313与轮轴12同轴设置，容纳孔313的孔壁上沿轴向开设有避让槽3131，避让槽3131贯通容纳孔313的开孔面，容纳孔313的孔壁上沿周向开设有切换孔3132，切换孔3132与避让槽3131连通。
可以理解的是，切换件31由同步连接轴段1211移动至转动连接轴段1212的过程中，切换件31逐渐远离从动轮23，止挡件13的连接部131以及止挡部132分别进入容纳孔313与避让槽3131内，且止挡件13的连接部131以及止挡部132沿避让槽3131以及容纳孔313移动。当切换件31移动至与转动连接轴段1212连接时，切换装置3处于第二工作状态，止挡件13置于容纳孔313与避让槽3131内，止挡部132与切换孔3132正对设置，此时切换件31能够相对轮轴12转动，以使止挡部132转入切换孔3132内，切换孔3132沿轮轴12轴向的两侧的孔壁能够止挡上述的止挡部132，以限制切换件31沿轮轴12轴向的位置。上述结构设置，使得切换装置3能够稳定地处于第二工作状态，防止由于手动推拉清洁设备产生的震动导致切换件31移动，从而切换至第一工作状态，保证了切换装置3的可靠度，进一步保证减少了来自电机21的阻力，也避免了电机21的反向上电，保证了电机21的使用寿命。
在本实施例中，如图10所示，切换件31包括环体315和连接体316，环体315位于连接体316朝向从动轮23的一端，连接体316相背于环体315的一端开设有容纳孔313，容纳孔313与环体315的中心通孔连通，使得轮轴12能够穿入。容纳孔313的孔壁与环体315的内侧壁组成切换件31的内侧壁，环体315的内侧壁包括首尾连接的第二平面部3151以及第二弧面部3152。其中，切换孔3132贯通连接体316的外侧壁与容纳孔313的孔壁，减少了对于止挡件13尺寸的限制，扩大了切换件31的适用范围，同时也便于装配，又减少了止挡部132碰撞挤压的可能性，提高了切换装置3的耐用性。
在本实施例中，止挡部132设置有两个，避让槽3131与切换孔3132也相应设置有两个。止挡部132远离切换件31的一侧凸出设置有凸棱133，切换孔3132远离从动轮23一侧的孔壁上开设有条形槽3133，当止挡部132与切换孔3132正对时，将切换件31转动至凸棱133卡入条形槽3133内，即表示切换件31转动到位，凸棱133与条形槽3133的设置避免了止挡部132脱离切换孔3132，而且也避免了切换件31转动角度较小导致止挡部132脱离切换孔3132，进一步保证切换装置3能够稳定地处于第二工作状态。
如图4、图6所示，切换装置3还包括连接盖33，连接盖33连接于切换件31远离从动轮23的一端，连接盖33上连接有握持件32，操作人员能够通过握持件32手动操作切换件31，提高了使用便利性。连接盖33上开设有第一穿孔331，第一穿孔331的形状与容纳孔313以及避让槽3131共同形成的形状相同，保证止挡件13能够通过第一穿孔331，而且连接盖33也能够保护切换件31，进一步提高了耐用性，也保证了美观程度。
在本实施例中，止挡件13的连接部131通过螺钉与轮轴12的端部连接。
本实施例中，容纳孔313内设置有弹性件4，弹性件4的一端抵接于止挡件13，另一端抵接于容纳孔313的孔底面。在清洁设备清洁工作时，切换装置3处于第一工作状态，弹性件4可处于自然状态或压缩状态。当需要切换至第二工作状态时，切换件31朝向远离从动轮23的方向移动的过程中，切换件31由同步连接轴段1211移动至转动连接轴段1212，止挡件13进入容纳孔313与避让槽3131内，弹性件4被压缩，切换件31转动至止挡部132转入切换孔3132，能够限制弹性件4的伸展。当需要切换回第一工作状态时，转动切换件31一定角度至止挡部132脱离切换孔3132，弹性件4的弹性力作用即可推动切换件31与止挡件13相互远离，使得切换件31移动至同步连接轴段1211上，实现自动切换至第二工作状态，提高了使用便利性。此处，弹性件4采用的为弹簧，其套设在轮轴12上。在其他实施例中，弹性件4还可为橡胶环或其他具有弹性的结构，也可不套设在轮轴12上，在此均不作限定。
在本实施例中，容纳部设置在切换件31的环体315上，凸出部231设置在从动轮23上。在其他实施例中，也可为容纳部设置在从动轮23上，凸出部231设置在切换件31上，也可在切换件31的侧壁上设置有容纳部，从动轮23上设置凸出部231，凸出部231能够沿径向嵌入或远离容纳部，实现从动轮23能够带动切换件31同步转动即可，在此不作限定。
具体地，如图9至图11所示，从动轮23的端面上设置有至少两个凸出部231，也就是说，容纳部也设置有至少两个。凸出部231沿轮轴12的轴向延伸。进一步地，环体315朝向从动轮23的端面上开设有环槽311，环槽311的侧壁上凸出且间隔设置有至少两个限位部312，限位部312沿轮轴12的轴线延伸，相邻两个限位部312之间形成容纳部，至少两个凸出部231能够一一对应置于至少两个容纳部内。切换装置3处于第一工作状态时，限位部312的侧壁能够与凸出部231抵触，使得切换件31与从动轮23之间不发生相对转动，实现电机21驱动轮轴12转动，保证了切换装置3能够可靠且稳定地处于第一工作状态，而且凸出部231与限位部312均沿轮轴12的轴向延伸，也能够对切换件31起到导向作用，避免切换件31在沿轮轴12轴向移动过程中转动，也就降低了止挡件13受到切换件31挤压而变形的可能性，保证了切换装置3的耐用性。
在本实施例中，相邻两个限位部312之间的间距与凸出部231的宽度相同，当凸出部231处于容纳部内时，凸出部231的两个侧壁能够分别与两侧的限位部312贴合。
本实施例中，从动轮23朝向切换件31的一端端面上同轴设有凸环232，凸出部231沿凸环232的周向间隔排布在凸环232的外侧壁上，设置凸环232也提高了从动轮23的结构强度，降低了凸出部231变形的可能性，保证了切换装置3的耐用性。可以理解的是，当切换装置3处于第一工作状态时，凸环232也处于环槽311内。为了避让凸环232，限位部312仅设置在环槽311的外侧环壁上。
进一步地，限位部312与凸出部231均呈条状，凸出部231朝向止挡件13的一端端面为第一V型面，第一V型面包括两个倾斜连接的第一导向面2311，第一V型面的开口朝向轮体11设置。限位部312朝向轮体11的一端端面为第二V型面，第二V型面包括两个呈角度连接的第二导向面3121，第二V型面的开口朝向止挡件13设置。上述设置，能够起到导向作用，保证凸出部231准确进入容纳部内，降低凸出部231与限位部312变形的可能性。
在其他实施例中，容纳部还可设置为凹槽，切换件31朝向从动轮23的端面上沿周向间隔开设有至少两个凹槽，至少两个凸出部231能够一一对应置于至少两个容纳部内，在此不作限定。
在其他实施例中，也可以为凸出部231沿凸环232的周向间隔排布在凸环232的内侧壁上，此时限位部312仅设置在环槽311的内侧环壁上，在此不作限定。
如图12至图14所示，本实施例的清洁设备还包括外壳5，轮轴12转动连接于外壳5，电机21与外壳5固定连接，电机21的输出轴同轴连接于主动轮22。外壳5与切换装置3、驱动装置2以及行走轮1均连接，形成一整体的行走轮驱动机构30而设于机体10的底部，提高了该部分结构的整体性，便于运输。
进一步地，如图7所示，外壳5上凸出设置有第一限位台阶522，切换件31的侧壁上凸出设置有第二限位台阶314，第一限位台阶522位于第二限位台阶314远离从动轮23的一侧，切换装置3处于第二工作状态时，第一限位台阶522与第二限位台阶314抵触。上述设置，能够限制切换件31沿轮轴12轴向的移动距离，避免了止挡件13受到切换件31的挤压导致变形，保证了切换装置3的耐用性。
在本实施例中，环体315的外侧壁朝向从动轮23的一端凸出设置有第二限位台阶314。第二限位台阶314呈环状，保证结构强度。
具体地，外壳5包括壳体51和盖体52，壳体51一端开口，盖体52封堵壳体51的开口，使得壳体51与盖体52围成外壳5的内腔。盖体52上开设有第二穿孔521，轮轴12的一端穿设于第二穿孔521，另一端与壳体51转动连接。主动轮22、从动轮23、同步带24、第二限位台阶314以及部分切换件31位于外壳5的内腔中，使得外壳5具有保护作用。轮轴12远离第二穿孔521的一端穿出外壳5并与轮体11连接。切换件31远离从动轮23的一端通过第二穿孔521伸出外壳5，且切换件31活动穿设第二穿孔521，实现切换件31沿轮轴12轴向的移动。第二穿孔521的孔壁远离轮体11的一端凸设有第一限位台阶522。第一限位台阶522呈环状，保证结构强度。
可以理解的是，设置第一限位台阶522和第二限位台阶314，也能够防止切换件31脱离外壳5，保证了外壳5的保护作用，也保证了切换件31能够缩回外壳5，能够降低维护成本。
在本实施例中，轮轴12还包括第四轴段124，第四轴段124上套设有轴承53，第四轴段124同轴连接在第三轴段123与第二轴段122之间，设置轴承53能够降低轮轴12与壳体51之间的摩擦力。
优选地，轴承53的内圈固定在轮轴12上，且内圈的端面与挡圈14贴合，壳体51远离盖体52一端的壳壁上开设有安装孔，轴承53置于安装孔内，且轴承53的外圈与安装孔的孔壁贴合并连接，安装孔的孔壁朝向盖体52的一端凸出设置有限位挡环55，安装孔朝向轮体11的一端设置有轴承限位件54，轴承53的外圈的两端分别与轴承限位件54以及限位挡环55贴合。由此，实现轴承53的轴向限位。
进一步地，轮体11朝向轴承53的端面也与轴承53接触，轮体11相背于轴承53的一端设置有端盖16，端盖16固定连接于轮轴12的端部，端盖16将轮体11与轴承53压紧，实现轮体11的轴向定位。
如图12至图16所示，本实施例中，机体10的底部设置有转动座6，转动座6上连接有调节转轴61，调节转轴61平行于机体10的底面设置，外壳5转动连接于调节转轴61。当清洁设备移动时，机体10的底面与工作区域的地面平行，上述设置，使得行走轮1、驱动装置2及切换装置3能够整体地相对机体10绕调节转轴61转动，实现行走轮驱动机构30的整体抬高或下降，当工作区域的地面上有凸出障碍物时，行走轮1在碰到障碍物时能够上下浮动，实现清洁设备的越障功能，行走轮1在越过障碍物后能够上下浮动，继续下降至与地面接触，实现移动的功能，提高了实用性，同时，转动座6与调节转轴61的设置也保护行走轮1和清洁设备，保证了耐用性，降低了维护成本。
在本实施例中，机体10底部开设有安装口101，行走轮驱动机构30整体置于安装口101内，转动座6的顶面固定在安装口101的顶面上，转动座6的下方转动连接有调节转轴61。外壳5的外侧壁上凸出设置有转动连接臂513，转动连接臂513与调节转轴61转动连接。清洁设备正常前进的情况下，行走轮1至少部分外露于安装口101，行走轮驱动机构30在碰到障碍物时能够绕调节转轴61转动并向上缩回安装口101，实现清洁设备越障的功能，行走轮驱动机构30在越过障碍物后能够绕调节转轴61转动并向下伸出安装口101，继续与地面接触。
进一步地，机体10沿左右方向间隔设置两个安装口101，安装口101贯通机体10对应侧的侧壁，连接盖33以及握持件32能够通过安装口101外露，便于通过握持件32拉动切换件31，实现切换装置3在第一工作状态以及第二工作状态之间切换，提高了操作便利性。
本实施例中，清洁设备还包括拉簧7，拉簧7的一端连接于机体10，拉簧7的另一端连接于外壳5；当行走轮驱动机构30在碰到障碍物时，行走轮驱动机构30上下浮动，拉簧7能够拉长，当行走轮驱动机构30在越过障碍物后，行走轮驱动机构30上下浮动，拉簧7收缩，拉簧7能够拉动行走轮驱动机构30复位，保证行走轮驱动机构30能够在越障后与地面可靠地接触，从而实现移动作用，提高了实用性，保证了耐用性，降低了维护成本。
本实施例中，清洁设备还包括连接件8，连接件8位于安装口101内且固定连接于机体10，连接件8呈壳状，拉簧7置于连接件8内部，连接件8上固定设置有一个拉簧轴71，外壳5的外侧壁上也固定有一个拉簧轴71，拉簧7的两端分别连接于两个拉簧轴71，且固定在连接件8上的拉簧轴71需要低于固定在外壳5上的拉簧轴71。外壳5上的拉簧轴71与转动连接臂513分别位于外壳5的相背两侧。对于拉簧轴71的具体位置不作限定，需要实现当行走轮驱动机构30在碰到障碍物时，两个拉簧轴71能够相互远离；当行走轮驱动机构30在越过障碍物后，两个拉簧轴71能够相互靠近。
连接件8上开设有滑道81，滑道81沿垂直于调节转轴61轴向的方向延伸，外壳5至少部分位于滑道81内并能够沿滑道81滑动。设置滑道81，能够对行走轮驱动机构30的转动起到导向作用，保证了行走轮驱动机构30越障作用的可靠性，也保证行走轮驱动机构30上浮后，能够沿滑道81复位，能够在越障后与地面可靠地接触，从而实现移动作用，提高了实用性，保证了耐用性，降低了维护成本。

上述实施例的清洁设备中，推拉部件20能够沿长度方向伸缩地设置，通过调整推拉部件20的工作状态以及调整切换装置3的工作状态，使得该清洁设备至少具有自动行走模式与推拉行走模式，当清洁设备处于自动行走模式下，推拉部件20沿长度方向缩短，且切换装置3处于第一工作状态，如图1所示，此时，清洁设备在驱动装置2的驱动作用下自动行走；当清洁设备处于推拉行走模式下，推拉部件20沿自身长度方向伸长，且切换装置3处于第二工作状态，如图3所示，此时，行走轮1在推拉部件20的牵引作用下行走，该行走模式下，行走轮1的轮轴12不再能由驱动装置2驱动旋转，用户在握持推拉部件20而推拉该清洁设备时，减小了来自驱动装置2的阻力，降低了推动清洁设备所需要的作用力，便于手动地推拉该清洁设备至目标位置，同时也避免了电机21的反向上电，保证了电机21的使用寿命，从而保证了清洁设备的耐用性，降低了维护成本。
该清洁设备还包括如图2所示的交互行走模式，该交互行走模式下，推拉部件20沿自身长度方向伸长，且切换装置3处于第一工作状态，此时，行走轮1在驱动装置2的驱动作用下行走，但清洁设备的行进方向由操作人员通过操控推拉部件20予以掌控，该交互行走模式主要用于在清洁设备执行清洁工作的过程中将清洁设备移动至需要的位置处，例如清除局部脏污，或者在清洁设备作业前的建图工作中，这为用户的日常使用带来了便利。
图18至图28示出了清洁设备中推拉部件20在机体10上具体设置方式的一些具体实施方式，其中，推拉部件20活动地连接于机体10上，该推拉部件20上至少具有供握持的手柄201。该推拉部件20具有相对机体10伸出的打开状态，以及相对机体10收拢的收起状态，其中，当该推拉部件20处于打开状态下，手柄201在竖直方向上高于机体10，使得操作人员方便地握持手柄201，从而通过推拉的方式来驱使清洁设备前进。
图18至图20示出了该清洁设备的其中一种实施方式，其中，推拉部件20与机体10滑动地连接，且推拉部件20的一端部能够绕一转动中心线转动地连接于机体10上。该实施例中，机体10上设置有提供推拉部件20滑动导向的导向部件，推拉部件20与上述导向部件滑动地连接，推拉部件20具有分设于自身长度方向相异两端的第一端部与第二端部，手柄201设置在第一端部上，由第二端部能够绕转动中心线转动地与导向部件连接。亦即，该推拉部件20上设置有手柄201的端部为第一端部，与导向部件连接的端部为第二端部。
导向部件上设置有沿其长度方向延伸的滑槽1061，第二端部上设置有转轴205，该转轴205固定地设于第二端部上，或者能够绕自身轴心线转动地设于第二端部上，转轴205滑动配合地穿设在滑槽1061中，且转轴205的轴心线构成上述的转动中心线。此处，导向部件包括相互平行且间隔地设置的两组滑轨106，每组滑轨106上均设有上述的滑槽1061，推拉部件20设于两组滑轨106之间。当然，在其他实施例中，滑轨106的数量也可以是一组，或者是相互平行且彼此平行设置的多组。
如图18至图22所示的实施例中，导向部件的导向方向，亦即上述滑轨106的长度延伸方向为沿水平方向延伸，使得推拉部件20能够沿水平方向相对导向部件滑动而与机体10相互收拢，相应地，收拢后的推拉部件20沿水平方向延伸。在其他的实施例中，如图25至图26所示的实施例，其中的导向部件的导向方向沿竖直方向延伸，使得推拉部件20能够沿竖直方向相对导向部件滑动而与机体10相互收拢，相应地，收拢后的推拉部件20沿竖直方向延伸。在其他实施例中，导向部件的导向方向与水平方向或者竖直方向呈一定的夹角设置，使得推拉部件20以倾斜的姿态相对机体10收拢。
参见图18至图22所示的实施例中，机体10上设置有容纳腔，以及与该容纳腔相连通的开口102，导向部件设置在容纳腔中，推拉部件20能够自开口102伸出至机体10外并转动任意角度而供操作人员握持而进行推拉操作，或者自开口102缩回并收容至容纳腔中。
推拉部件20在打开状态下能够沿自身长度方向伸缩而实现长度的调整。在需要移动时，操作人员需要拉动推拉部件20，使其先滑动至机体10外，然后绕转轴205转动至合适的角度后拉伸推拉部件20，使其保持合适的长度，该长度刚好满足操作人员操作时所需要的长度，设计合理，操作人员可以通过推拉部件20将清洁设备推拉至任何需要打扫的位置后启动工作，以满足不同场所的使用需求，或者是将清洁设备进行转移至其他需要的目标位置。在不需要推拉机体10时，操作人员缩短推拉部件20后使其绕转轴205转动至与开口102正对的状态，然后推动推拉部件20，使其滑动至容纳腔内，以将推拉部件20完全收纳于机体10内，不占用多余的空间。该清洁设备移动方便，节省人力，能够适用于不同的场所，通用性较强，且可以灵活调整推拉部件20的长度和角度，方便收纳，且收纳后推拉部件20与机体10的外形融为一体，节省空间，保证了机体10外观的完整性和美观性。
如图18所示，该清洁设备还包括盖板103，转动地设于机体10上，用于封堵开口。在其他实施例中，还可以将盖板103扣设于机体10上。通过将盖板103以转动连接于机体10上或者可拆卸的方式卡接于机体10上，与机体10的上盖形成了完整的盖板结构，保护机体10的内部结构，保证清洁设备外观的美观和完整。如图20所示，当需要使用推拉部件20时，只需提前转动盖板103或者将盖板103从机体10上拆卸下来，使得开口102露出，方便推拉部件20从开口102处伸出，其中，开口102的大小只需适配推拉部件20的截面面积即可，盖板103的大小与开口102的大小相适配。如图1所示，当使用完毕将推拉部件20收纳于容纳腔内后，将盖板103扣合即可，盖合或打开均比较方便。
参见各附图所示，推拉部件20包括多个能够沿长度方向滑动伸缩地连接的拉杆单元，通过多个拉杆单元之间的滑动来实现推拉部件20长度的调整。该推拉部件20至少包括与机体10连接的第一拉杆单元202，以及一端部设置有上述手柄201的第二拉杆单元203。如图18至20所示的实施例中，推拉部件20的拉杆单元为2个，即第一拉杆单元202与第二拉杆单元203，该第一拉杆单元202与第二拉杆单元203滑动地嵌套连接，第一拉杆单元202与第二拉杆单元203之间还设置有伸缩调整组件(图中未示出)，手柄201上设置有控制按钮2011，控制按钮2011与伸缩调整组件连接，按压控制按钮2011能够控制伸缩调整组件使第一拉杆单元202与第二拉杆单元203之间锁定或解锁。在使用时，操作人员可以按下控制按钮2011对第一拉杆单元202与第二拉杆单元203之间进行解锁，使推拉部件20拉伸到合适长度后，松开控制按钮2011对各拉杆单元之间进行锁紧后便可正常使用。其中，伸缩调整组件与控制按钮2011的配合使用为现有技术，其具体结构不是本公开的重点，在此不做赘述。
在其他实施例中，推拉部件20的拉杆单元也可以是多于2个，即，在第一拉杆单元202与第二拉杆单元203之间还嵌套设置有一个或多个第三拉杆单元207，该第三拉杆单元207的数量优选地为0个至5个。例如图23至图24所示的实施例中，第一拉杆单元202与第二拉杆单元203之间还嵌套有一个第三拉杆单元207。
参见图20至图22所示，推拉部件20还包括固设于第一拉杆单元202上的卡扣件204，该卡扣件204具有卡扣部2041，机体10上设置有能够与卡扣部2041相互配合卡扣固定的配合部104，当推拉部件20处于收起状态时，上述卡扣部2041能够与配合部104相互卡合固定，使得推拉部件20收起时能够相对机体10固定，避免其从容纳腔中脱出。此处，卡扣部2041为卡槽，配合部104为凸起；在其他的一些实施例中，如图23、图24所示，还可以是将配合部104设置呈卡槽，将卡扣部2041设置为凸起。
如图21至图22所示的实施例中，第一拉杆单元202与第二拉杆单元203均具有相互平行且间隔地设置的两个，手柄201固设于两个第二拉杆单元203的一端部，卡扣件204固设于两个第一拉杆单元202上且卡扣部2041位于两个第一拉杆单元202之间。两个第一拉杆单元202上远离手柄201的端部上均设置有转轴205，且转轴205滑动地设于对应侧滑轨106的滑槽1061中。这样设置，使得推拉部件20的整体结构更加稳固，推拉时清洁设备运行更加平稳。
图21至图22所示的实施例中，每个第一拉杆单元202上转轴205的数量设置为两个，分别位于第一拉杆单元202相对的两侧，并且每个第一拉杆单元202的两侧均设置有滑轨106，每个转轴205均与对应滑轨106上的滑槽1061配合。采用这种设置，能够使得两个第一拉杆单元202的滑动更加稳定顺畅。参考图21，需要说明的是，每个第一拉杆单元202对应设置两个滑轨106，两个滑轨106的底端相连接形成“U”形的一体成型结构，并通过紧固件安装于机体10的容纳腔内。通过采用这种设置，安装时更加方便快捷，且减少了连接件的使用，从而减轻了清洁设备的整体重量。另外，两个滑轨106相连接形成凹槽，第一拉杆单元202能够容置于上述凹槽内，以对第一拉杆单元202形成导向作用。
优选地，如图22所示，滑槽1061的末端设置为圆弧状。可以理解的是，转轴205为圆柱形结构，将滑槽1061的末端设置为圆弧状，是为了和转轴205的形状相适配，减小摩擦力，使得转动过程更加顺畅。
在使用本实施例的清洁设备时，可以按照如下推拉方法：
步骤S1：将推拉部件20拉出机体10外，使其调整为打开状态，具体包括：
步骤S11：拉动推拉部件20，使其沿滑轨106滑动至机体10外；
步骤S12：将推拉部件20绕转轴205相对滑轨106的末端转动至合适角度；
步骤S13：拉伸推拉部件20，以使其调整为合适长度。
步骤S2：通过推拉部件20将清洁设备推拉至预设位置；
步骤S3：将推拉部件20收纳于容纳腔内，具体包括：
步骤S31：收缩推拉部件20，使其调整为最短长度；
步骤S32：将推拉部件20绕转轴205相对滑轨106的末端转动至容易沿滑轨106推动的状态：
步骤S33：推动推拉部件20，使其沿滑轨106滑动至容纳腔内。
在将推拉部件20相对机体10打开后，通过推拉该推拉部件20来驱使清洁设备行进的过程中，推拉部件20不会与机体10发生干涉。操作人员还可以灵活地调整推拉部件20的长度和角度，方便收纳，且收纳后推拉部件20与机体10的外形融为一体，节省空间，保证了机体10外观的完整性和美观性。
图27至图28示出了该清洁设备的另一种实施方式，其中，推拉部件20与机体10转动地连接。本实施例中，清洁设备还包括拉盖105，该拉盖105绕一旋转中心线转动地连接于机体10上，推拉部件20设置在拉盖105上并能够随着该拉盖105共同绕旋转中心线相对机体10转动，从而能够相对机体10打开或者收拢，具体地，当推拉部件20处于打开状态下，拉盖105相对机体10打开；当推拉部件20处于收起状态下，拉盖105与机体10之间形成一封闭的容置空间，推拉部件20收容于上述容置空间内，以保护清洁设备的内部结构，保证清洁设备整体的美观和安全。
如图28所示，拉盖105打开后，推拉部件20即可使用，即操作人员握住手柄201并绕旋转中心线转动，以调整到合适角度，然后拉伸推拉部件20，使其保持合适的长度，推拉至目标位置即可，操作方便，节省人力。
进一步地，拉盖105远离旋转中心线的一端设置有卡扣结构，扣合时能够卡接于机体10上，操作方便。拉盖105远离旋转中心线的一端开设有缺口，方便操作人员将手指伸入，并将拉盖105打开。
如图28所示，该实施例中，推拉部件20通过固定件206锁紧于拉盖105上。具体而言，固定件206套设于两个第一拉杆单元202外，固定件206再通过螺钉固定于拉盖105的内侧，这种设置使得推拉部件20和拉盖105之间连接稳固。进一步优选地，固定件206的数量设置为多个，进一步提高了推拉部件20与拉盖105之间连接的稳定性。在本实施例中，固定件206的数量设置为两个，两个固定件206分别套设于最下端第一拉杆单元202的底部和顶部，并分别与拉盖105锁紧。
在其他的一些实施例中，还可以将推拉部件20的一端部直接地转动连接于机体10上，实现推拉部件20相对机体10的打开或收拢。可选地，另外活动地设置拉盖，使得推拉部件20相对机体10收拢后，通过拉盖与机体10的连接，将推拉部件20收容于机体10与拉盖之间的容置空间内。
需要说明的是，本公开的上述实施例仅仅是为了清楚说明本公开所作的举例，而并非是对本公开的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡根据本公开的实质内容所作的任何修改、等同替换和改进等，均应包含在本公开权利要求的保护范围之内。
