下面参照附图对本发明所涉及的吸尘器吸嘴和吸尘器具进行详细说明。
<实施例一〉
在本实施例一中, 吸尘器具包括: 吸尘器吸嘴 10、 风道连接部以及吸尘部。 吸 嘴 10 与风道连接部相配套, 用来清洁宠物身上的毛发等待清洁物。 吸尘部为吸尘 10提供吸引力, 对被吸尘器吸嘴 10清洁的毛发、 灰尘等进行吸附, 并作为吸尘器 构对这些待清洁物进行收容。
如图 1, 2, 3, 4, 5, 6, 7, 8所示, 吸尘器吸嘴 10用于梳理并清洁宠物的毛发, 它 包括: 上盖部 21, 驱动构件 12, 中盖 22, 梳理构件 13, 下盖部 23 (见图 3 )。 另有梳理 开口 71位于上盖部 21、 中盖 22和下盖部 23所形成的本体的前部下方, 风门 70位于梳理 开口 71的后方 (见图 2)。
梳理构件 13 包含转动体和形成在该转动体上的至少一个梳齿部, 该梳齿部含有基座 28和复数个梳齿 29, 梳齿 29被固定在基座 28上, 这复数个梳齿 29的排列方向与风门 70 的长度方向相一致。 在本实施例一中, 转动体包括基座凸柱 59、 基座凹孔 60和连接该基 座凸柱 59与基座凹孔 60的连接板, 转动体的转动能够带动基座 28进行转动, 梳齿 29截 面形状平直, 而且伸展方向与转动体的轴向相垂直, 并沿与转动体的轴向相平行的方向排 列在基座 28的表面。梳理构件 13有梳理状态和收纳状态两种位置状态,在梳理状态下(即、 梳齿 29处于梳理位置时), 梳齿 29从梳理开口 71向外伸出, 用于梳理宠物毛发。 在收纳 状态下 (即、 梳齿 29处于清理位置时), 梳齿 29指向风门 70并能停驻在风门 70的前方 (见图 3 )。
下盖部 23的后方带有出气口 79和中空把手 50, 出气口 79也就是中空把手 50的进气 口。 中空把手 50的后方带有接口 80用于连接吸尘器具的风道连接部 (见图 3 )。
上盖部 21设有推钮孔 51, 推钮 20从推钮孔 51中穿过。 上盖部 21还具有漏气窗 52, 位于风门 70的外侧, 跟梳理开口 71分别处于梳理构件 13的转动体的上下两侧, 用于保 证梳理状态时有足够的风量进入风门 70, 防止梳理过程中梳理开口 71被宠物身体与毛发 堵住而使得吸尘器具的吸尘部的吸力全部施加在宠物身体上, 进而给宠物带来不适。 同时 保证在收纳状态时, 梳齿 29的上下两个方向都有吸入气流进入风门 70, 从梳齿 29上下两 方同时用力, 更易于将毛发剥离梳齿。 上盖部 21还设有卡扣孔 53, 用于跟下盖部 23的卡 扣 66啮合, 使得上盖部 21与下盖部 23能可靠配合, 形成空腔以便容纳其它零件和机构 (见图 3 )。
中盖 22设有四个卡扣 62, 用于压住连杆 24, 确保连杆 24能按照卡扣 62和导向筋 81 设定的路径前后运动, 不会翘起或者扭曲。 中盖 22还设有弹簧挡块 63, 用于固定弹簧 25 的前端。 中盖 22还设有风门上挡板 61, 与下盖部 23上的风门下挡板 68相对, 形成风门 70, 位于梳理开口 71和中空把手 50之间 (见图 2、 3 )。
风门上挡板 61的高度 HI和风门下挡板 68的高度 H2都可以为零 (见图 7 (A))。 本 实施例中它们的高度都不为零, 使得风门 70 的截面积小于其前方外部的通风截面积。 上 盖部 21和下盖部 23在本实施例中都是平直的形状, 上盖部 21可以做成向上凸起的圆弧 形, 下盖部 23也可以做成向下凸起的圆弧形。 风门 70的长度 E不小于梳齿 29在基座 28 上的分布范围的长度 A (见图 5 )。风门 70截面积的最优方案为分别小于风门 70前方和后 方的通风截面积, 即风门由气流通道缩口而形成。
下盖部 23设有出气口 79和中空把手 50, 用户可以握住中空把手 50的外壁来使用该 宠物梳理器。 中空把手 50的外壁可以光滑, 也可以带有条纹, 或者做成其它粗糙的表面, 还可以包覆软胶, 以便防滑。 下盖部 23还设有引风道 72, 位于风门 70和中空把手 50之 间。 如图 5中点划线与下盖部 23的内壁所围成的区域所示, 在本实施例一中, 引风道 72 具有与风门 70相连通的前导区 73和与中空把手 50相连通的后导区 74。前导区 73的长度 B不小于风门 70的长度 E, 前导区 73沿吸入气流方向的深度 C不小于 3毫米。
在本实施例一中, 中空把手 50和引风道 72构成了与风道连接部相连通的风道部。 当梳齿 29处于收纳状态时, 面向风门 70的所有梳齿都指向风门 70的内部, 齿尖与 风门 70之间的距离不超过 10毫米, 梳理构件 13, 风门 70以及引风道 72的前导区 73的 位置与尺寸关系如此设定: 确保指向风门 70内部的任意梳齿 29的伸展方向都跟经过该梳 齿 29的吸入气流方向平行或者近似平行 (见图 7 (B) )。 也就是指向风门 70内部的任意梳 齿 29的伸展方向都跟引风道 72的前导区 73在吸入气流方向上的截面平行。
前导区 73的左右侧壁的最优方案是直线形 (即、 前导区 73在从风门 70到中空把手 50的方向上具有矩形的截面), 后导区 74的形状最优方案是以圆弧形式向出气口 79汇聚 (如图 5 )。 在保证长度大于风门 70长度的前提下, 前导区 73的外形也可以是其它形状。 前导区 73与后导区 74沿吸入气流方向的深度要足够深, 要能保证流经左右边缘梳齿 29 的吸入气流方向跟梳齿 29 的伸展方向相互平行或者近似平行。 满足深度要求之后, 后导 区 74也可以采用其它形状。
下盖部 23还设有卡扣 66, 卡扣 66与上盖部 21的卡扣孔 53啮合, 使得上盖部 21与 下盖部 23能可靠配合, 容纳其它零件和机构。
下盖部 23还设有圆孔 67, 用于安置传动圈 27。 传动圈 27的内孔 58为圆柱形。 下盖 部 23还设有锁紧孔 69, 锁紧孔 69上设有通槽 69a和锁紧槽 69b, 端盖 30内侧的锁紧块 65可以穿过通槽 69a到达锁紧槽 69b的入口,这时沿逆时针方向旋转工具槽 78,可以使锁 紧块 65深入锁紧槽 69b并与锁紧槽 69b紧密配合 (见图 3 )。 有必要的时候, 往工具槽 78 中插入一个类似硬币的金属片或塑料片并顺时针旋转, 就可以向外取出端盖 30, 进而取出 梳理构件 13进行维护或者替换。
在实施例一中, 梳理构件 13的转轴, 风门 70, 引风道前导区 73沿吸入气流方向的截 面 75, 以及中空把手 50的中心线, 四者位于同一水平面上。 四者也可以不水平, 中空把 手 50的中心线与引风道前导区 73可以形成一定夹角, 比如 135°左右 (见图 9)。
如图 3所示, 在本实施例一中, 下盖部 23上沿着前导区 73的左右两侧向风门 70外 侧延伸的两个部分, 作为两个安装臂, 用来可转动地安装转动体。
驱动构件 12包含推钮 20、 连杆 24、 齿轮 26、 传动圈 27、 端盖 30。 推钮 20带有卡扣
76, 与连杆 24上的长方孔 77配合, 用于推动连杆 24前进。 连杆 24设有长方孔 77、 和用 于容纳弹簧 25的弹簧腔 55。 连杆 24还设有齿条 54, 用于跟齿轮 26上的受动齿 56啮合。 齿轮 26设有齿轮内孔 57, 用于容纳基座凸柱 59。
驱动构件 12还包含端盖 30, 端盖 30上设有端盖凸柱 64, 与梳理构件 13的基座凹孔 60配合, 用于支承基座 28. 端盖 30还设有三个锁紧块 65, 锁紧块 65与下盖部 23上的锁 紧孔 69进行配合, 用于固定端盖 30, 端盖 30还设有工具槽 78和定位凸筋 82, 定位凸筋 82用于把锁紧块 65固定在锁紧孔 69内, 防止窜动 (见图 3 )
转动体设有基座凸柱 59和基座凹孔 60, 两者都是圆柱形。传动圈内孔 58悬挂在基座 凸柱 59上, 两者配合紧密同时留有适当的转动间隙, 使得梳理构件 13能围绕转动体的轴 向自如转动。 基座凹孔 60悬挂在端盖凸柱 64上, 两者也都是圆柱形, 配合紧密同时留有 适当的转动间隙, 使得梳理构件 13能围绕转动体的轴向自如转动。
梳齿 29可以通过注塑方式跟基座 28结合, 也可以在基座 28上预留槽孔, 然后把梳 齿 29压入槽孔。
梳齿 29 的形式可以为排梳、 针梳、 锯齿状刀片以及其它各种通用的梳齿形式, 截面 形状平直, 而且在基座 28上的伸展方向跟转动体的的轴向方向相垂直。
梳齿 29可以采用不锈钢材料、 塑料材料以及其它各种常用于宠物梳齿的材料。 动作描述- 在本实施例一中, 先把该吸尘器吸嘴 10 与吸尘器具的风道连接部相连接, 确保梳齿 29从梳理开口 71 向外伸出, 接通吸尘器具的电源, 吸入气流通过梳理开口 71和漏气窗 52进入风门, 通过引风道 72的前导区 73与后导区 74, 再经过出气口 79和中空把手 50 流向吸尘部的集尘室。 这时可以开始用该吸尘器吸嘴 10梳理宠物。
当梳齿 29上积累一定量的毛发之后, 用户可以用拇指把推钮 20往前推, 其余四指握 紧中空把手 50的外壁。 推钮 20带动连杆 24前进, 连杆 24前进过程中, 在压缩弹簧 25 的同时, 连杆 24上的齿条 54推动齿轮 26上的受动齿 56, 使齿轮 26向前方转动, 带动传 动圈 27向前转动, 传动圈 27带动梳理构件 12以单摆的形式从梳理状态转向风门 70并能 停驻在风门 70的前方进入收纳状态, 梳齿 29指向风门 70内部 (见图 7A图 7B), 同时使 梳齿 29的伸展方向与引风道 72的前导区 73在吸入气流方向上的截面平行, 或者近似平 行。 此时, 梳理开口 71和漏气窗 52分别从梳齿 29上下两个方向往风门 70传输气流, 吸 入气流方向跟指向风门 70的任意一根梳齿 29的伸展方向平行, 吸入气流只要能克服毛发 与梳齿 29之间的摩擦力, 就能使毛发脱离梳齿 29进入风门 70。
为了更有效地让吸入气流带走毛发, 梳理构件 12 上凡是接触毛发的地方都要光滑圆 润, 防止挂住毛发。
拇指松开推钮 20之后, 弹簧 25从深度压缩状态复位, 推动连杆 24后退复位, 连杆 24上的齿条 54带动受动齿 56往后转动, 进而通过传动圈 27带动梳理构件 13摆动复位, 使得梳齿 29回到梳理状态。
端盖 30外侧带有工具槽 78, 可以用类似硬币的金属片或塑料片拧转端盖 30, 把它与 锁紧孔 69松开并取出来, 进而可以依次取出梳理构件 13进行维护或者替换。
该吸尘器吸嘴 10 可以跟吸尘器具的软管 (即、 风道连接部) 直接相连, 也可以通过 一个转接硬管或者转接软管再与吸尘器软管相连。 转接硬管或者转接软管的接口可以做成 不同的口径, 以便跟不同口径的吸尘器软管配合。
上述实施例中只有一排梳齿, 当梳齿指向风门时, 可以用挂钩或者挡块或者其它机构 把梳理构件固定, 使梳齿能长久停留在收纳状态, 以便减小该吸尘器吸嘴的外形尺寸, 便 于包装运输, 也避免梳齿外露, 防止意外受损。
驱动构件也可以不用齿轮和齿条, 而是包含卷簧 (螺旋弹簧) 和连杆, 卷簧 (螺旋 弹簧) 的中心轴线与梳理构件的转动体的轴向相平行。 用户通过连杆来驱使梳理构件中的 梳齿以单摆形式从梳理状态转到收纳状态并能停在收纳状态指向风门, 在摆动过程中卷簧 (螺旋弹簧) 受力变形, 连杆松开之后, 卷簧 (螺旋弹簧) 复位的弹力将驱使梳理构件摆 回梳理状态。
实施例一的作用与效果
根据实施例一所描述的吸尘器吸嘴和吸尘器具, 因为梳齿的伸展方向与转动体的轴向 相垂直, 并且风门的长度方向与转动体的轴向相平行, 风门的长度不小于一排梳齿在基座 上分布范围的长度, 同时, 引风道具有与风门相连通的前导区, 前导区的长度不小于风门 的长度, 并且前导区在从风门向着接口构件的方向上具有一定的深度, 所以不论是流经位 于基座的中间的梳齿, 还是流经位于左右最边缘的梳齿的气流方向都跟梳齿的伸展方向相 互平行或者近似平行, 使得在收纳状态下任意梳齿上缠绕的毛发都能随风被吸入风门。
另外, 因为端盖外侧带有工具槽, 可以用类似硬币的金属片或塑料片插入该工具槽中 来拧转端盖, 把端盖与锁紧孔松开并取出来, 进而可以依次取出梳理构件, 所以非常便于 使用者对梳理构件进行维护和替换。
此外, 本实施例的吸尘器吸嘴采用单摆结构, 在保证用户能以单手操作实现梳毛和吸 毛功能的同时, 也简化了驱动机构, 降低了材料成本, 使之更易于普及, 同时也降低了产 品尺寸和重量, 专业用户长久连续使用也不易觉得疲劳, 使得产品更加轻便可靠。
<实施例二〉
如图 10, 11, 12, 13, 14, 15, 16所示, 一种吸尘器吸嘴 100包括: 上盖部 110、 下 盖部 111以及梳理构件 101。
上盖部 110设有风门上挡板 152a, 与下盖部 111上的风门下挡板 152b相对而形成风 门 152。 (见图 16 (A) )
上盖部 110还设有密封筋 155, 与下盖部 111上的密封槽 151通过超声波焊接紧密配 合, 起密封作用。 密封筋 155和密封槽 151也可以用胶水或者其它方式进行配合。
下盖部 111上设有中空把手 150, 用于跟吸尘器连接, 也用于操作该吸尘器吸嘴 100. 如图 12所示, 下盖部 111还设有密封槽 151和风门下挡板 152b。 下盖部 111的前方 设有右支架 163,右支架 163中设有定位槽 153a、定位槽 156a、转轴孔 154a、限位槽 155a。 下盖部 111的左前方是左支架 164, 左支架 164中设有定位槽 153b、 定位槽 156b、 转轴孔 154b, 限位槽 155b。 (见图 12、 13 )
如图 12、 14所示, 下盖部 111的中部设有引风道 160, 引风道 160包含前导区 160a 和后导区 160b, 后导区 160 b的出气口 161就是中空把手 150的进气口。 中空把手 150的 出气口 162也是跟吸尘器相配合的接口。
梳理构件 101包含一个转动体 167和两个梳齿部,这两个梳齿部中一个位于梳理位置, 另一个位于清理位置。 在本实施例中, 这两个梳齿部之间形成约 98 ° 的夹角。 一个梳齿部 包括: 基座 112和梳齿 113a、另一个梳齿部包括: 基座 112和梳齿 113b。转动体 167的 左 侧设有限位筋 157 b、 基座转轴 158b、 定位筋 159 b (见图 12), 分别与左支架 164上对应 的槽孔相配合。 转动体 167的右侧设有限位筋 157a, 基座转轴 158a, 定位筋 159 a (见图 13 ), 分别与右支架 163 上对应的槽孔相配合。 转动体左右两侧的筋轴与左右支架内侧对 应的槽孔构成转动构件。
如图 12、 14所示, 在本实施例二中, 左支架 164和右支架 163分别沿着前导区 160a 的左右两侧向着风门 152外侧延伸, 作为两个安装臂, 用来可转动地安装转动体 167。
梳齿 113a和 113b的形式可以是针梳, 排梳等各种常用形式, 材料可以是塑料, 也可 以是金属等种类, 尺寸可以是各种常用的梳齿尺寸。 梳齿 113a和 113b最优方案是完全相 同, 也可以分别采用不同的形式。
左支架 164和右支架 163都采用弹性比较好的材料制成, 在自由状态下, 左支架 164 和右支架 163可以往相背离的方向移动 3毫米左右。 梳理构件 101的左右两端长度比左支 架 164和右支架 163在自由状态时的距离大 2毫米左右。 因为材料的弹性, 左支架 164和 右支架 163能夹紧梳理构件 101。 只要把左支架 164或者右支架 163向外移动, 就可以取 出梳理构件 101进行维护或者替换。
动作描述- 在本实施例二中, 先把该吸尘器吸嘴 100与吸尘器相连接, 确保梳齿 113a向外伸出, 此时另外一组梳齿 113b指向风门 152内部(见图 16A)。此时转动体 167右侧的定位筋 159a (见图 13 ) 与右支架 163的定位槽 153a (见图 12) 啮合。 转轴孔 154a与基座转轴 158a 啮合, 使得梳理构件 101可以绕基座转轴 158a转动。 限位筋 157a与限位槽 155a啮合, 并 且只能在限位槽 155a活动。 定位筋 159a和限位筋 157a的局部放大图见图 12. 转动体 167 左侧与左支架 164上零件的对应关系也是如此。
接通吸尘器电源, 吸入气流通过梳理开口 165和漏气窗 166进入风门 152, 通过引风 道 160的前导区 160a与后导区 160b, 再经过出气口 161和中空把手 150流向吸尘器集尘 室。 这时可以开始用该吸尘器吸嘴梳理宠物。
当梳齿 113a上积累一定量的毛发之后, 用户握紧中空把手 150, 把梳齿 113a轻轻推 向宠物的身体, 利用梳齿 113a充当转动机构的触发元件, 使得转动体 167右侧的定位筋 159a从右支架 163的定位槽 153a转入定位槽 156a内, 转轴孔 154a依然与基座转轴 158a 配合, 限位筋 157a在限位槽 155a内部转到一个新的角度, 协助定位筋 159a在新的定位槽 156a内站稳。带有毛发的梳齿 113a随着定位筋 159a的移动而转向风门 152并指向风门 152 内部, 梳齿 113 b则从风门 152前方向上转动, 从漏气窗 166向上伸出。 此时吸入气流从 梳理开口 165和漏气窗 166同时流向风门 152, 从上下两个方向同时用力, 把积累在梳齿 113a上的毛发推向风门,然后沿引风道 160进入中空把手 150,进而飞向吸尘器积尘室(见 图 13 )。
然后, 用户握住中空把手 150把吸嘴 100翻转 180度, 使得梳齿 113 b指向下方, 就 可以继续进行梳理工作。
显然,在实施例二中,梳理开口 165和漏气窗 166的位置持续互换。比如梳理开口 165, 当它位于下方时, 梳齿 113a向外伸展用于梳理。 当该吸嘴 100翻转之后, 梳理开口 165 转到上方, 梳齿 113b转到下方进行梳理, 这时梳理开口 165实际上转变成漏气窗 166, 而 漏气窗 166实际上转变成梳理开口 165。
如图 14,风门 152长度 L不小于梳齿在基座 112上的分布范围的长度 0,前导区 160a 的长度 K不小于风门 152的长度 L。前导区 160a沿吸入气流方向的深度 M不小于 3毫米。 当梳齿处于收纳状态指向风门 152时, 梳齿尖端跟风门 152的距离不大于 10毫米。
本实施例二中, 上盖部 110与下盖部 111的外形平直。 上盖部 110也可以做成圆弧形 向上凸起, 下盖部 111的外形可以做成圆弧形向下突出。 风门 152截面积的最优方案为分 别小于风门前方和后方的通风截面积, 即风门 152由气流通道缩口而形成。
实施例二的作用与效果
根据实施例二所描述的吸尘器吸嘴, 因为梳齿的伸展方向与转动体的轴向相垂直, 并 且风门的长度方向与转动体的轴向相平行, 风门的长度不小于一排梳齿在基座上分布范围 的长度, 同时, 引风道具有与风门相连通的前导区, 前导区的长度不小于风门的长度, 并 且前导区在从风门向着接口构件的方向上具有一定的深度, 所以不论是流经位于基座的中 间的梳齿, 还是流经位于左右最边缘的梳齿的气流方向都跟梳齿的伸展方向相互平行或者 近似平行, 使得在收纳状态下任意梳齿上缠绕的毛发都能随风被吸入风门。
另外, 因为左支架和右支架都采用弹性比较好的材料制成, 只要把左支架或者右支架 向外移动, 就可以取出梳理构件, 所以非常便于使用者对梳理构件进行维护和替换。
此外, 本实施例的吸尘器吸嘴仅需单手操作, 操作起来更加简单、 方便, 并且由于该 吸尘器吸嘴结构简单所以也更加轻便可靠。
