下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本申请手持吸尘器包括主机、吸尘杆和吸尘件，主机作为吸尘的动力元件，产生抽吸作用力；吸尘件作为与待清洁空间接触的元件，灰尘由吸尘件被吸入；吸尘杆则是作为吸尘件和主机之间的连接杆，以便于用户手持。主机作为手持吸尘器中重量最大的元件，其设置的位置决定了手持吸尘器的直立放置的稳定性，也决定了用户手持的耗力程度。例如本申请中主机可位于吸尘杆高位或低位，在低位时，手持吸尘器的重心偏下，利于手持吸尘器稳定的直立放置；在高位时，方便狭小空间的吸尘，且在如天花板高处吸尘时，也更加省力。
本申请手持吸尘器通过主机相对吸尘杆的旋转结构来实现主机处于不同位置，具体请参阅附图，附图中图1-4为手持吸尘器中主机的结构示意图，图5-8为手持吸尘器中吸尘杆的结构示意图，图9-14为手持吸尘器的结构示意图。
请参与图1-4，本申请提出一种主机，本实施例主机100包括主机壳11、集尘盒12、风机13和电池14。集尘盒12、风机13和电池14由主机100上部到下部的方向依序设置于主机壳11内。
主机壳11上设置有尘盒接口111，尘盒接口111连通于位于主机壳11内的集尘盒12。尘盒接口111连通于手持吸尘器中的吸尘杆，以实现吸尘。即无论主机100相对吸尘杆运动到哪个位置，尘盒接口111均需要连通于吸尘杆，以实现吸尘。因而在本实施例中，主机100以尘盒接口111为旋转中心部相对吸尘杆转动，继而能够转动至吸尘杆的不同位置。
尘盒接口111位于主机100上部，主机100内集尘盒12、风机13和电池14由上部到下部依次设置，本实施例中，集尘盒12、风机13和电池14的重量依次增大，主机100的重心在下，因而将尘盒接口111设置为上部，能够进一步保证主机100转动至吸尘杆低位时，主机100的重心尽量低；主机100转动至吸尘杆高位时，主机的重心能够尽量高。
主机100以尘盒接口111为旋转中心部转动，有多种转动方式，主要分为尘盒接口111相对吸尘杆转动或不转动的两种方式，例如尘盒接口111固定设置在主机壳11上，尘盒接口111转动连接于吸尘杆；或者，尘盒接口111转动设置在主机壳11上，尘盒接口111固定连接于吸尘杆。
综上，本实施例中主机100以尘盒接口111为旋转中心部即表示，尘盒接口111作为旋转中心部，主机100旋转的中心轴是穿过尘盒接口111的，且主机100能够在吸尘杆的长轴的平行面上旋转，即主机100的旋转面平行于吸尘杆的长轴。在一些实施例中，尘盒接口111与主机壳11的转动连接处，或尘盒接口111与吸尘杆的转动连接处可以为圆形，主机100旋转的中心轴穿过该圆形的中心，且主机100所形成的旋转平面也与圆形平面平行。
本实施例中主机100由上部到下部具有长轴，主机100为对称结构例如圆柱体，则长轴为其中轴线，尘盒接口111与吸尘杆的连接处形成的连接面与长轴平行，以保证主机100在转动时不会出现歪斜的情况，即在转动时，主机100与吸尘杆的间距保持不变。
由于主机100较重，在转动时不容易控制，因而针对主机100和吸尘杆的相对转动还设置有阻尼结构，具体在主机壳11上设置有第一阻尼件15，在主机100相对吸尘杆转动过程中，第一阻尼件15和吸尘杆上的第二阻尼件相互作用，以产生转动阻力。
第一阻尼件15具体为阻尼圈，套设在尘盒接口111外周，朝向吸尘杆的表面间隔设置有多个阻尼槽151，多个阻尼槽151环绕尘盒接口111设置。第二阻尼件为阻尼销，嵌设在阻尼槽151中，主机100转动时，阻尼圈随着转动，阻尼销与阻尼槽151的嵌设关系会产生一定的转动阻力。
为了使转动有一定阻力的同时也保证顺滑，阻尼销为圆球形，弹性连接在吸尘杆上，阻尼槽151为圆球槽，且槽口为弧形，以平滑连接于平面。
实现主机100稳固连接在吸尘杆上，主机壳11上还设置有位于主机100下部的子固定件112，主机11的上下部分别通过尘盒接口111和固定件112固定于吸尘杆上。子固定件112可以是固定柱，对应的在吸尘杆上设置具有母固定件，母固定件包括设置有固定槽的限位块，固定柱可嵌入到固定槽槽内。进一步的，还可在固定槽内设置弹性销，相应的固定柱上形成有卡位槽，弹性销用以卡入固定件112的卡位槽内，以固定主机100。
本实施例主机壳11的下部还形成有废气孔113，主机100中的风机13进行抽风，灰尘及风流由吸尘件、吸尘杆进入到集尘盒12，继而经过风机13和电池14最终由废气孔113排出，废气孔113为栅格状。
电池14在主机壳11中环绕设置，围绕形成中空通道，使得风流经过电池14更加顺畅，且风流经过电池14，还能对电池14起到散热作用。
本实施例主机100能够以尘盒接口111为旋转中心，相对吸尘杆转动，即可转动至吸尘杆的不同位置，从而可适应于吸尘器的不同使用场景。具体来说主机可转动至吸尘杆上的高位或低位，保证吸尘功能的同时，在高位实现窄空间的吸尘，以及天花板的省力吸尘，在低位实现自主直立放置，以及地面的省力吸尘。
请参阅图5-8，本申请提出一种吸尘杆，本实施例吸尘杆200的第二端设置有手持部21，第一端用于连接手持吸尘器的吸尘件，吸尘杆200两端之间形成有集尘接口22，集尘接口22 则用于连接手持吸尘器的主机，吸尘杆200内形成有吸尘通道23，该吸尘通道23连通于集尘接口22和吸尘件。
本实施例中的集尘接口22使得主机能够以集尘接口22为旋转中心部转动，继而可以使主机转动到吸尘杆200的不同位置，从而适应于不同的使用场景。例如主机可转动至第一位置和第二位置，第一位置为第一端和集尘接口22之间，第二位置为第二端和集尘接口22之间。主机转动至第二位置即位于吸尘杆200的高位，主机转动至第一位置即主机位于吸尘杆200的低位。
为了方便主机的连接，集尘接口22设置在吸尘杆200的侧面，吸尘通道23包括连通吸尘件的竖直通道231和连接集尘接口22的水平通道232。吸尘通道23内的风流方向会有一个方向的变化。由于吸尘通道23内还需要抽吸灰尘，因而在竖直通道231和水平通道232的连接处设置为圆角连接，便于灰尘的流动以及风的流动，避免灰尘在角落的沉积。
主机连接至集尘接口22，并能够基于集尘接口22转动至吸尘杆200的上下两个位置，且当主机转动至第一和第二位置时，主机基本全部位于第一端和集尘接口22之间，或第二端和集尘接口22之间。因而将集尘接口22设置在吸尘杆200的中间，即第一端到集尘接口22的距离与第二端到集尘接口22的距离近似相同，且近似等于主机的长度，这样的设计可使得吸尘杆200的长度为最优长度，即使得空间利用率最大。本实施例中第一端到集尘接口22的距离与第二端到集尘接口22的距离的差值设置为小于或等于一个预设值，本实施例中可将此预设值设置为5cm。以保证两距离的近似相同。
并且，集尘接口22与主机的连接处形成的连接面与吸尘杆的长轴平行，保证主机在转动时相对吸尘杆200不会歪斜，即在转动时，主机和吸尘杆200的间距保持不变。
由于主机较重，在转动时不稳定，因而在吸尘杆200上还设置有第二阻尼件24，位于集尘接口22的外周。第二阻尼件24与主机上的第一阻尼件相互作用，以在主机相对吸尘杆200转动时，产生转动阻力。
第一阻尼件具体为阻尼圈，套设在尘盒接口外周，朝向吸尘杆的表面间隔设置有多个阻尼槽，多个阻尼槽环绕尘盒接口设置。第二阻尼件24为阻尼销，嵌设在阻尼槽中，主机转动时，阻尼圈随着转动，阻尼销与阻尼槽的嵌设关系会产生一定的转动阻力。
为了使转动有一定阻力的同时也保证顺滑，阻尼销为圆球形，弹性连接在吸尘杆上，阻尼槽为圆球槽，且槽口为弧形，以平滑连接于平面。
在本实施例吸尘杆200上还设置有母固定件25，母固定件25和集尘接口22共同作用，使得主机能够固定在吸尘杆200的第一位置或第二位置。本实施例中母固定件25为固定设置在吸尘杆200上，应用于主机固定在第二位置的情况。本实施例中在吸尘杆200或吸尘件上还可设置一母固定件，以应用于主机固定在第一位置的情况。
母固定件25可以是固定设置在吸尘杆200上，还可拆卸式地设置在固定件112上。其他实施例中，若母固定件25为可拆卸结构，则可在主机转动至第一位置时，将母固定件25拆卸设置在第一对应位置以固定主机；而当主机转动至第二位置，则将母固定件25拆卸设置到第二对应位置固定主机。
母固定件25具体为固定块，固定块上形成有固定槽251，固定槽251的朝向对应主机转动方向，即当主机转动到高位时，主机上的子固定件可直接卡置于固定槽251中。固定槽251内还设置有弹性销252，弹性销252进一步卡置子固定件，以使得子固定件与母固定件的连接更加稳固。弹性销252具体包括球形销以及连接球形销和限位槽的弹簧。
吸尘杆200的第一端连接吸尘件，具体为插接结构27，可与吸尘件插接固定，且方便拆卸。当用户需要不同的吸尘件时，方便更换。
吸尘杆200的第二端设置有手持部21，手持部21上还设置有操作开关26，以便于控制主机的开启，本实施例中操作开关26与主机信号连接，具体可有线通信连接或无线通信连接，例如通过吸尘杆200与主机电线连接，还可在主机中设置无线通信模块，操作开关26通过无 线通信模块与主机连接，以开关主机。
吸尘杆200可以分为吸尘段29和操作段28，集尘接口22和吸尘通道23形成在吸尘段29，手持部21和操作开关26则形成在操作段28；集尘接口22设置的位置靠近操作段28，操作段28和吸尘段29的长度近似相等，本实施例中，操作段28和吸尘段29的长度差设置为小于或等于20cm。操作段28无需设置风道，吸尘段29则可只设置风道；若操作开关26需要电线连接，则可仅在操作段走电线，吸尘段29则无需走电线，吸尘段29的吸尘通道23设置电连接端以连接主机和操作段28的操作开关26。
本实施例吸尘杆200上所设置的集尘接口22用于连接主机，且使得主机能够以集尘接口22为旋转中心进行转动，使得主机能够转动至吸尘杆200的不同位置，继而适用于不同场景下的使用。具体的主机可固定连接到吸尘杆200的高位或低位，保证吸尘功能的同时，在高位实现窄空间的吸尘，以及天花板的省力吸尘，在低位实现自主直立放置，以及地面的省力吸尘。
请参阅图9-14，本申请提出一种手持吸尘器，本实施例手持吸尘器400包括主机100、吸尘杆200和吸尘件300。主机100、吸尘杆200和吸尘件300依次连通实现吸尘清洁。
本实施例中，吸尘杆200上的集尘接口22位于吸尘杆200的两端之间，主机100可转动至吸尘杆200的不同位置，即可位于吸尘杆200的高位连接于集尘接口22，也可位于吸尘杆200的低位连接于集尘接口22。在高位处实现窄空间的吸尘，以及天花板的省力吸尘，在低位实现自主直立放置，以及地面的省力吸尘。
并且主机100只需以集尘接口22为转动中心部相对吸尘杆200转动即可实现高位和低位的转换。无需拆卸重新安装，便于用户操作，且利于手持吸尘器400的结构稳定性。
主机100和吸尘杆200的具体结构已在上文进行描述，具体结构不再赘述，以下主要描述两者的配合关系。
主机100上的尘盒接口111连接于集尘接口22，主机100相对吸尘杆200的转动，可通过尘盒接口111和集尘接口22的相对转动设置，即尘盒接口111和集尘接口22均作为主机100相对吸尘杆200转动的转动中心部，由于尘盒接口111和集尘接口22相互连接，主机100的转动的中心轴穿过尘盒接口111和集尘接口22所在的位置，例如，在本实施例中两接口的连接处均设置为圆筒形，相互插接，因而可实现相对转动，主机100转动的中心轴即为圆筒的中心轴。
为实现转动，主机100的尘盒接口111还可转动设置在主机壳11上，此时尘盒接口和主机壳11的连接处为圆筒形，实现转动连接；尘盒接口111和集尘接口22固定连接即可，两接口连接处的形状则可为任意形状。
另外，集尘接口22也可转动设置在吸尘杆200上，集尘接口22在吸尘杆200的连接处为圆筒形，实现转动连接。主机100的尘盒接口111固定设置，尘盒接口111与集尘接口22固定连接即可。两接口连接处的形成可为任意形状。
对于重量较重的主机100，如果转动太过顺滑，则容易出现转动不稳的问题。因而在主机100和吸尘杆200之间设置阻尼结构，包括主机100上设置的第一阻尼件15和吸尘杆200上的第二阻尼件24。
两阻尼件相互作用以形成转动阻力，具体结构参考上文所述。本实施例中，为阻尼圈的第一阻尼件15还可用作尘盒接口111和集尘接口22的辅助连接结构，具体来说，阻尼圈套设于尘盒接口111和集尘接口22的连接处，在集尘接口22的外周形成有卡接槽221，阻尼圈的内周则形成有卡接部152，卡接部152卡接在卡接槽221中，且能够在卡接槽221内转动。该结构的阻尼圈使尘盒接口111和集尘接口22的连接更加稳定，且在一定程度上能够避免两接口连接处的漏风问题。
主机100在转动后，连接到吸尘杆200的高位或低位，主机100和吸尘杆200的稳固连接主要通过主机100上的固定件112和吸尘杆200上的第一母固定件25，以及吸尘杆200或 吸尘件300上的母固定件。本实施例以第二母固定件321设置在吸尘件300上为例进行描述，若在吸尘杆200上，则同理设置。
第一母固定件25和第二母固定件321均用于与固定件112连接，本实施例中两结构相同，若为了便于其他元件的设置，两结构也可以设置为不同，保证均能与固定件112连接即可。
如上文所述，第一母固定件25和第二母固定件321均包括固定块，固定块上形成固定槽，固定槽内设置有弹性销，子固定件112为固定柱，其上形成有卡位槽1121，当子固定件112固定于第一母固定件25和第二母固定件321中时，固定柱嵌入固定槽中，弹性销卡入卡位槽1121内。
本实施例中，第一母固定件25和第二母固定件321的固定槽朝向相同，主机100在相对吸尘杆200转动时，只会转动半圈，以固定在第一母固定件25和第二母固定件321，且转动不易受干扰。
吸尘件300用于接触到吸尘空间，可以为多种结构，例如地刷结构(如图14)，窄管结构(如图15)等，连接于吸尘杆200的第一端，具体连接于插接结构27，本实施例中吸尘件300可拆卸的连接于吸尘杆200，其他实施例中吸尘件300也可与吸尘杆200为不可拆卸连接。
若吸尘件300为地刷结构，其包括吸尘地刷31和转动连接于吸尘地刷31的地刷接头32，吸尘杆200连接于地刷接头32，因而吸尘杆200可相对吸尘地刷31转动，从而便于用户操作。
地刷接头32上设置有第二电接头322，与吸尘地刷31电连接。主机100上设置有第一电接头16，当主机100转动至吸尘杆200低位时，第一电接头16连接至第二电接头322，继而主机100可为吸尘件300供电。在此基础上，本实施例中吸尘杆200中无需再为吸尘件300设置电连接结构。在与吸尘件300的连接处只需设置吸尘通道即可，简化了吸尘杆200的结构。
具体来说，第一电接头16具体为两个弹性顶针，第二电接头322具体为两个导电片，弹性顶针和导电片一一对应连接。此外，在本实施例中，第一电接头16与子固定件112可集成在一起，均设置在主机100的下部。
本实施例中吸尘地刷31的电驱动结构包括滚刷和驱动滚刷的驱动电机，第二电接头322电连接驱动电机；或者吸尘地刷31包括射流喷嘴和向射流喷嘴供风的射流风机，第二电接头322电连接射流风机。
具有射流喷嘴的吸尘地刷31是通过喷出射流以将地面上的灰尘扬起，继而便于吸尘，其相较于滚刷，更适用于毛毯，或灰尘较深的地缝清洁中。
对于具有射流喷嘴的吸尘地刷，除了通过射流风机供风，还可利用主机100中的废气供风，主机100上设置有排风口17，连通于主机壳11；在地刷接头32中设置连通射流喷嘴311的供风通道323，在主机100转动至吸尘杆200低位时，排风口17连通供风通道323，主机壳11内的废气由排风口17，经供风通道323提供给射流喷嘴324。
本实施例主机100连接吸尘杆200，且能够相对吸尘杆200转动至高位或低位，使用户使用更省力，针对转动设置有阻尼结构，便于转动的稳定。在高位或低位对应设置有限位结构，便于主机100能够固定连接于吸尘杆。且在低位时，主机100能够直接为吸尘件300供电，相应的吸尘杆200的结构可以更加简单。
