筛板及猫砂箱
优先权信息
本申请要求以下专利申请的优先权和权益，其全部内容通过引用结合在本申请中：2021年08月25日提交至中国国家知识产权局的、申请号为202122024276.1、名称为“筛板及猫砂箱”的中国专利申请。
技术领域
本实用新型属于宠物用品技术领域，具体涉及一种筛板及具有该筛板的猫砂箱。
背景技术
饲养宠物猫是不少人的爱好，但养猫最麻烦的事莫过于清理猫的粪便，除了训练猫在指定的地方排泄粪便，还要方便清理。目前市场上早已推出专用供猫排泄的排便盆，还根据猫的生活习性使用猫砂铺设在排便盆内，因猫在排泄时须选择有沙砾的地方，便后猫还会用猫爪将粪便用沙砾掩埋。之前人们用煤渣、煤灰铺设在猫便盆内，然后将混有猫粪便的煤渣煤灰倾倒掉。目前城市鲜见使用煤球炉，故无法收集煤渣煤灰，更多使用成本售价较高的猫砂。猫在猫砂上便溺后，其尿液浸湿猫砂，猫砂在收干后会结成块状，然后主人将脏污的猫砂倾倒掉。然而猫便溺仅浸湿便盆内部分猫砂，将整盆猫砂倒掉，既浪费资源，提高养猫的人经济负担，也加重对环境的污染。如果为了节约猫砂，每次清理猫砂则需要用铲子不断在猫砂盆中翻转寻找结块的猫砂，既不卫生也不方便。
实用新型内容
本实用新型的目的是至少解决成块状的猫砂在猫砂箱中分离不便的问题。该目的是通过以下方式实现的：
本实用新型的第一方面提出了一种筛板，用于猫砂盆的转筒中，其中，所述筛板包括：

根据本实用新型的筛板，通过将筛板的板体设有多个第一筛孔和多个第二筛孔，第一筛孔和第二筛孔均为条形孔，且第一筛孔的长度方向和第二筛孔的长度方向呈角度设置，能够对猫砂进行多角度的反复过滤，从而满足对多种形状猫砂的筛分，保证将块状的猫砂保留在板体上，而剩余的猫砂通过第一筛孔和第二筛孔进行掉落，将受污染的呈块状的猫砂与干净的猫砂进行有效地分离，方便对猫的排泄物进行清理，保证了猫砂箱的清洁，同时减少了猫砂的浪费。
另外，根据本实用新型的筛板，还可具有如下附加的技术特征：

具体实施方式
下面将参照附图更详细地描述本实用新型的示例性实施方式。虽然附图中显示了本实用新型的示例性实施方式，然而应当理解，可以以各种形式实现本实用新型而不应被这里阐述的实施方式所限制。相反，提供这些实施方式是为了能够更透彻地理解本实用新型，并且能够将本实用新型的范围完整的传达给本领域的技术人员。
应理解的是，文中使用的术语仅出于描述特定示例实施方式的目的，而无意于进行限 制。除非上下文另外明确地指出，否则如文中使用的单数形式“一”、“一个”以及“所述”也可以表示包括复数形式。术语“包括”、“包含”、“含有”以及“具有”是包含性的，并且因此指明所陈述的特征、步骤、操作、元件和/或部件的存在，但并不排除存在或者添加一个或多个其它特征、步骤、操作、元件、部件、和/或它们的组合。文中描述的方法步骤、过程、以及操作不解释为必须要求它们以所描述或说明的特定顺序执行，除非明确指出执行顺序。还应当理解，可以使用另外或者替代的步骤。
尽管可以在文中使用术语第一、第二、第三等来描述多个元件、部件、区域、层和/或部段，但是，这些元件、部件、区域、层和/或部段不应被这些术语所限制。这些术语可以仅用来将一个元件、部件、区域、层或部段与另一区域、层或部段区分开。除非上下文明确地指出，否则诸如“第一”、“第二”之类的术语以及其它数字术语在文中使用时并不暗示顺序或者次序。因此，以下讨论的第一元件、部件、区域、层或部段在不脱离示例实施方式的教导的情况下可以被称作第二元件、部件、区域、层或部段。
为了便于描述，可以在文中使用空间相对关系术语来描述如图中示出的一个元件或者特征相对于另一元件或者特征的关系，这些相对关系术语例如为“内部”、“外部”、“内侧”、“外侧”、“下面”、“下方”、“上面”、“上方”等。这种空间相对关系术语意于包括除图中描绘的方位之外的在使用或者操作中装置的不同方位。例如，如果在图中的装置翻转，那么描述为“在其它元件或者特征下面”或者“在其它元件或者特征下方”的元件将随后定向为“在其它元件或者特征上面”或者“在其它元件或者特征上方”。因此，示例术语“在……下方”可以包括在上和在下的方位。装置可以另外定向(旋转90度或者在其它方向)并且文中使用的空间相对关系描述符相应地进行解释。
如图1所示，本实施方式的猫砂箱具有转筒10和筛板20，其中转筒10的内部设有收容腔11，筛板20以可拆卸的方式设于收容腔11，并以可转动的方式与转筒10的内壁相连，从而对转筒10内的猫砂进行过滤筛分，将其中被污染成块状的猫砂排出至转筒10的外部，将剩余的干净猫砂保留在转筒10的收容腔11中，从而继续用于对猫的排泄物进行收集，实现对猫砂的自动分离，有效地减少猫砂的浪费。
结合图2至图4所示，本实施方式的筛板20包括板体21和连接端22。其中，本实施方式的板体21包括第一弧形面S1、第二弧形面S2和第三弧形面S3，第一弧形面S1、第二弧形面S2和第三弧形面S3沿板体21的延伸方向依次顺序设置的。其中，第一弧形面S1和第二弧形面S2分别朝向不同的方向凸起设置，并使二者呈S型结构。第二弧形面S2和第三弧形面S3分别朝向不同的方向凸起设置，并使二者呈S型结构，从而使第一弧形面S1、第二弧形面S2和第三弧形面S3沿侧面方向，整体呈波浪形结构。其中，第二弧形面S2所对应的圆心角小于第一弧形面S1和第三弧形面S3所对应的圆心角，第二弧形面S2所对应的圆弧半径大于第一弧形面S1和第三弧形面S3所对应的圆弧半径，从而便于将猫砂通过第二弧形面S2滑落至第一弧形面S1和第三弧形面S3上，进而对猫砂进行筛分。通过上述波浪形结构的设置，能够有效地增加板体21的筛分面积，从而有助于在猫砂与筛板20的相对运动过程中，增加猫砂与筛板20的接触面积，进而将被污染成块状的猫砂与剩余的干净猫砂进行有效地分离。在本申请的其他实施方式中，也可仅设置一个或两个弧形面，通过一个或两个弧形面对猫砂进行筛分，或将一个或两个弧形面与平面连接配合，通过平面和弧形面的配合延长对猫砂的筛分面积，从而对猫砂进行筛分，或可设置更多个 弧形面，通过多个弧形面共同对猫砂进行有效的筛分。
进一步地，本实施方式转筒10两端的端面与转筒10轴向方向的内壁面间采用圆弧过渡。为保证筛板20匹配地设置于转筒10的内部，防止在转筒10的转动过程中筛板20与转筒10的内壁面间发生干涉，板体21上延伸方向的末端的宽度尺寸逐渐减小。其中，板体21的长度方向尺寸即为板体21延伸方向的尺寸，板体21的宽度方向的尺寸即与板体21延伸方向相垂直的方向的尺寸。具体地，本实施方式中第三弧形面S3的宽度尺寸沿自身延伸方向逐渐减小，从而以便将筛板20安装于转筒10的内部，并有效地防止与转筒10的内壁面间发生干涉。
再结合图2至图4所示，本实施方式的第一弧形面S1、第二弧形面S2和第三弧形面S3均设有多个第一筛孔211和多个第二筛孔212，第一筛孔211的长度方向和第二筛孔212的长度方向呈角度设置。
为描述方便，本实施方式中仅以第一弧形面S1上的多个第一筛孔211和多个第二筛孔212为例进行说明。具体地，本实施方式的第一筛孔211和第二筛孔212均为条形孔，具体为跑道型，即矩形孔的四个直角处分别采用圆弧过渡。第一筛孔211的长度方向和第二筛孔212的长度方向呈90°夹角设置。当猫砂在筛板20上相对于筛板20的延伸方向运动时，第一筛孔211的长度方向和第二筛孔212的长度方向呈角度设置，能够对猫砂进行多角度的反复过滤，满足各种形状的猫砂的尺寸要求，从而将块状的猫砂保留在板体21上，而剩余的干净猫砂通过第一筛孔211和第二筛孔212进行掉落，将受污染的呈块状的猫砂与干净的猫砂进行有效地分离，进而减少了猫砂的浪费。在本实施方式的其他实施方式中，第一筛孔211的长度方向和第二筛孔212的长度方向还可以呈任意角度设置，在此不作限定。
进一步地，本实施方式的多个第一筛孔211沿第一方向间隔设置，多个第二筛孔212沿第二方向间隔设置，且第一方向和第二方向为同一方向，该方向与板体21的延伸方向相垂直，且在板体21的延伸方向，第一筛孔211和第二筛孔212交替排列设置，通过上述多个第一筛孔211和多个第二筛孔212的排列方式，能够有效地利用板体21的板面面积，从而提高板体21上的开孔率，进而提高对猫砂的筛分效果。
进一步地，本实施方式中第一筛孔211的长度方向与板体21的延伸方向相一致，即第一筛孔211沿弧形面的延伸方向设置，而第二筛孔212的长度方向垂直与第一筛孔211的长度方向设置，即第二筛孔212沿与弧形面的延伸方向相垂直的方向设置。
其中，本实施方式的第一筛孔211的长度尺寸大于第二筛孔212的长度尺寸，第一筛孔211的宽度尺寸小于第二筛孔212的宽度尺寸，从而通过第一筛孔211和第二筛孔212的组合，能够对现有市面上的大部分猫砂进行筛分，从而有效地保证对猫砂的筛分效果，减少猫砂的浪费
结合图1、图4和图5所示，本实施方式的筛板20还包括连接端22，连接端22包括连接板221和与连接板221相连的多个L型构件222，多个L型构件222沿连接板221的长度方向间隔设置，其中连接板221的长度方向与板体21的延伸方向相垂直。连接板221的一侧端部与板体21的延伸方向的起始端相连，连接板221的另一侧端部与多个L型构件222相连。其中，连接端22与板体21可以为一体式结构，也可以为可拆卸式结构。相应地，本实施方式的转筒10的内壁上设有与L型构件222插接配合的安装槽12。本实施 方式中的转筒10内壁上设有多个间隔设置的安装槽12，L型构件222以可转动的方式插接于安装槽12内，从而实现筛板20在转筒10的收容腔11中转动，使被污染成块状的猫砂沿板体21上的第一弧形面S1、第二弧形面S2和第三弧形面S3运动，增加猫砂与板体21的筛分面积，并将干净的猫砂通过第一筛孔211和第二筛孔212掉落至转筒10的底部，使成块状的受污染的猫砂保留在板体21上，并最终随转筒10的转动通过排污口13排出至转筒10的外部，进而有效地实现猫砂的分离。
进一步地，本实施方式的L型构件222远离连接板221的一端设有弧形凸起2221，弧形凸起2221朝向连接板221所在的方向设置，从而在L型构件222的转动过程中与安装槽12的内壁面相配合。通过弧形凸起2221与安装槽12的内壁面相配合，能够增加筛板20转动时的顺畅度，从而有效地对保证对猫砂的分离效果。
进一步地，本实施方式的转筒10的内壁设有防粘层。防粘层可以为转筒自身的部分结构，如设置在转筒10的内壁面的铁氟龙防粘涂层，或其他材质的防粘涂层。在本申请的其他实施方式中，防粘层还可以是以可拆卸的方式与转筒10内壁面相连的PTU材质的防粘垫，防粘垫可以通过卡接或粘结的方式与转筒10的内壁面相连。通过在转筒10的内部设置防粘层，能够有效地防止猫的排泄物粘结在转筒10内壁上，从而便于对转筒10的内壁进行有效地清理，保证猫砂箱的清洁，减少异味和细菌的产生，从而有助于猫的成长和健康。
根据本实用新型的猫砂箱，通过在猫砂箱的转筒10内部设置可转动的筛板20，并将筛板20的板体21设置成包括多个弧形面，并在任一个弧形面上分别设有多个第一筛孔211和多个第二筛孔212，能够有效地增加板体21的筛分面积，从而有助于在猫砂与筛板20的相对运动过程中，增加猫砂与筛板20的接触面积，同时第一筛孔211的长度方向和第二筛孔212的长度方向呈角度设置，能够对猫砂进行多角度的反复过滤，从而将块状的猫砂保留在板体21上，而剩余的猫砂通过第一筛孔211和第二筛孔212掉落至转筒10的底部，将受污染的呈块状的猫砂与干净的猫砂进行有效地分离，方便对猫的排泄物进行清理，保证了猫砂箱的清洁，进而减少了猫砂的浪费。
以上所述，仅为本实用新型较佳的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本实用新型的保护范围之内。因此，本实用新型的保护范围应以权利要求的保护范围为准。
