下面结合附图，对本公开的具体实施方式进行详细说明。
请参阅图1，图1为本公开提供的刷头10应用于牙刷100的结构示意图。
本公开提供一种刷头10，该刷头10具有不易残留污渍，便于清理，且刷毛15较稳固的特点。该刷头10能够应用于牙刷100及清洁刷等，当然，该刷 头10也能够独立使用。
其中，以刷头10应用于牙刷100为例进行说明，该牙刷100包括刷头10，以提高牙刷100的整洁度，当然，该牙刷100还可包括刷杆20，刷头10连接于刷杆20，刷杆20配置成供使用者拿持，便于使用牙刷100。
此外，牙刷100还可包括驱动件30，该驱动件30可安装于刷杆20，且能够带动刷头10运动，例如，该驱动件30为电机，其可带动刷头10转动或振动，当然，该驱动件30也可为超声波换能器，其设置于刷杆20或刷头10内，以增强清洁效果。
由于牙刷100采用了本公开提供的刷头10，所以该牙刷100也具有不易残留污渍，便于清理，且刷毛15较稳固的特点。
以下将具体介绍本公开提供的刷头10的结构组成、工作原理及有益效果。
请参阅图2、图3及图4，图2为本公开提供的刷头10的部分结构爆炸示意图。图3为本公开提供的刷头10的部分结构的另一爆炸示意图。图4为本公开提供的刷头10的部分结构熔融连接后的结构示意图。
该刷头10包括刷柄12和刷毛15，刷毛15与刷柄12熔融连接，以避免刷毛15与刷柄12有较多的间隙，进而降低残留污渍的几率，更易清理，此外还使得刷毛15更加稳固，不易出现掉毛的情况。
请结合图1和图3，其中，刷柄12上设有相背的刷洗面121和固定面122，或者说，刷洗面121和固定面122分别位于刷柄12相对的两侧。并且，在刷柄12上开设有多个同时贯穿刷洗面121和固定面122的连接通孔123，或者说，连接通孔123由固定面122延伸至刷洗面121。
可选的，刷毛15穿设于连接通孔123内。可选的，每个连接通孔123内 穿设有一个刷毛15，刷毛15的部分沿远离刷洗面121的方向凸出于固定面，且刷毛15凸出于固定面122的部分为刷毛熔接部151，在固定连接刷毛15和刷柄12时，通过刷毛熔接部151与固定面122共同熔融连接，以在固定面122上形成覆盖于固定面122的熔融连接片152，也就是说，刷毛熔接部151和固定面122熔接为一体，且熔接的部分还形成一个覆盖于固定面122上的熔融连接片152。
这样一来，通过熔接形成完全覆盖于固定面122的熔融连接片152，使得刷毛15和固定面122的连接处无任何间隙，进而降低刷头10残留污渍的几率，更易清理。此外，成片的熔融连接方式使得刷毛15的多根毛体的部分与刷柄12熔融为一体，多根独立的毛体与刷柄12形成一个整体结构，使得刷毛15与刷柄12的连接更加稳固，刷头10不易出现掉毛的情况。
需要说明的是，刷柄12和刷毛15采用的熔融连接的方式可以为热熔连接、超声波熔接或者高周波熔接等。此外，现有的刷头片与刷柄12采用活动连接的方式，其可靠性低，易产生噪音，震动效果差，不适应电动牙刷100地使用，且刷头片与刷柄12之间易进水，难以清洁。并且，现有的刷头片与刷柄12的连接方式，刷头片与刷柄12的连接位置位于刷头片的边缘，占用了刷头片配置成安装刷毛15的位置的面积，其使得刷头片配置成安装刷毛15的面积减小。而本公开中采用位于刷洗面121背面的固定面122与刷毛15熔融连接的方式，其不占用刷洗面121与刷毛15的连接面积，本公开的刷头10可以具有较多的刷毛15，提高用户的使用体验。
请参阅图3，可选的，连接通孔123的横截面形状为非圆形，其中，连接通孔123的横截面是指垂直于连接通孔123的轴线的平面。对应的，刷毛15的横截面外轮廓形状与连接通孔123的横截面形状匹配，当刷毛15穿设在对应的连接通孔123内后，刷毛15不会绕连接通孔123的轴线相对于连接通孔123转动，刷毛15的位置更加稳固，便于熔接固定。可选的，连接通孔123 的横截面形状包括椭圆形、腰形或者多边形中的至少一种，显然，连接通孔123的横截面形状按需选择，在此不进行一一列举。此外，多个连接通孔123的横截面形状可以设置为不同。
请参阅图2和图3，在固定面122上沿远离刷洗面121的方向还可凸设熔接凸起124，该熔接凸起124沿固定面122的边缘延伸，也即熔接凸起124沿固定面122的环向延伸，熔接凸起124呈环状，也就是说，熔接凸起124环设于固定面122上。多个连接通孔123均位于熔接凸起124所围成的区域内，也即，多个刷毛15穿设在对应的连接通孔123内后，多个刷毛15伸出固定面122的部分均位于熔接凸起124围成的区域内。
并且，在刷柄12和刷毛15熔接时，熔接凸起124、刷毛熔接部151及固定面122共同熔融连接，以共同形成熔融连接片152。
这样一来，使得熔融连接片152的边缘与熔接凸起124的内壁熔合为一体，进而使得熔融连接片152的边缘更加牢固，能够适应电动牙刷100的振动，不易在使用中产生间隙。换句话说，在形成熔融连接片152时，刷毛15、熔接凸起124和固定面122的交接位置处可能会形成熔接痕，通过将熔接凸起124围绕熔融连接片152设置且将二者熔接为一体，熔接凸起124能够覆盖熔融连接片15的边缘，从而消除熔融连接片15的熔接痕，以使得熔融连接片15的边缘更加牢固。
需要说明的是，在本公开中，熔接凸起124为连续环设于固定面122的凸起。可选的，熔接凸起124也可为多个沿固定面122的边缘的延伸方向设置的凸起，相邻的凸起之间具有间隙。刷柄12和刷毛15熔接固定时，刷毛熔接部151、固定面122以及多个凸起共同熔接为一体。
请参阅图5，图5为图3中V处的局部放大结构示意图。
在固定面122上沿远离刷洗面121的方向还可凸设有多个加固凸起125，多个加固凸起125与刷毛熔接部151共同熔融连接，以共同形成熔融连接片152，加固凸起125配置成共同参与熔融连接，增加熔融连接片152的厚度，进一步提高熔融连接片152的牢固程度。
可选的，任意相邻两个连接通孔123之间共同的侧壁为分隔体，分隔体包括相连的第一分隔体1221和第二分隔体1222，可选的，第一分隔体1221和第二分隔体1222的厚度不同，本公开中，第一分隔体1221的厚度大于第二分隔体1222的厚度，其中，厚度是指位于同一分隔体上的两个连接通孔123各自的壁面之间的距离。
可选的，多个加固凸起125均分布设置于第一分隔体1221上，也就是说，刷毛15插接在对应的连接通孔123后，刷毛15的刷毛熔接部151凸出于第一分隔体1221，相邻刷毛熔接部151之间的间隙为第一分隔体1221或者第二分隔体1222的厚度，对于较厚的第一分隔体1221所对应的刷毛15之间的间隙，通过对应设置加固凸起125以增加上述间隙位置的熔融量，以提高熔融连接片152的牢固性。而在较薄的第二分隔体1222上未设置加固凸起125，一则是因为在第一侧壁1221设置加固凸起125足以满足熔融连接片152连接的牢固性，二则是可以降低刷头10的成本。
需要说明的是，在本公开中，刷柄12为PP材质，刷毛15为尼龙材质，并且，第一分隔体1221的厚度设计范围为0.80mm至0.96mm。可选的，本公开中，第一分隔体1221的数量为多个，多个第一分隔体1221的厚度值包括0.86mm，0.9mm，0.87mm，及0.83mm。可选的，第二分隔体1222的厚度设计范围为0.41mm至0.53mm，可选的，在本公开中，第二分隔体1222的厚度为0.47mm。可选的，加固凸起125为圆柱体，该圆柱体的设计尺寸为：直径范围为0.54mm至0.66mm，高度范围为0.54mm至0.66mm。可选的，在本公开中，该圆柱的高度为0.60mm，且直径为0.60mm。可选的，刷毛熔接部151与加固 凸起125等高，以使得在刷毛熔接部151、加固凸起125及固定面122共同熔接形成的熔融连接片152上各个位置厚度值的误差小于0.05mm，从而提高熔融连接片152的平整度。
可选的，多个加固凸起125也可分布于任意相邻的两个连接通孔123之间共同的侧壁上，换句话说，在第一分隔体1221和第二分隔体1222上均布设有至少一个加固凸起123，进一步加强熔融连接片152的牢固程度。
可选的，第一分隔体1221和第二分隔体1222上均设置有多个加固凸起125，第一分隔体1221和第二分隔体1222均呈长条形，位于第一分隔体1221上的多个加固凸起125沿第一分隔体1221的延伸方向间隔排布，位于第二分隔体1222上的多个加固凸起125沿第二分隔体1222的延伸方向间隔排布。
请继续参阅图3和图4，刷头10还可包括加固件17，加固件17与刷柄12连接。可选的，加固件17注塑连接于熔融连接片152，并覆盖熔融连接片152，在熔融连接片152上注塑加固件17进一步加固熔融连接片152，既提高了刷毛15连接的可靠性，又未留有间隙，从而可以防止水等污渍进入刷头10内部，避免了藏污纳垢，也降低了噪音，震动效果有明显的改善。
可以理解的是，加固件17可以为硬胶或软胶材料，如PP材料或硅胶材料。
可选的，在刷柄12上还开可设有加固凹槽127，加固凹槽127沿固定面122的周向延伸，加固凹槽127围绕熔接凸起124呈环形结构。加固件17覆盖加固凹槽127，换言之，加固件17同时与熔融连接片152和刷柄20注塑连接，加固件17具有与加固凹槽127匹配的环形凸部，使得加固件17与加固凹槽127卡接配合，进一步提高加固件17与刷柄12连接的稳固性。
此外，在熔接凸起124、刷毛熔接部151和加固凸起125共同熔接形成熔融连接片152时，还会形成位于熔接凸起124所围成的区域内的熔接凹槽126， 加固件17还覆盖于熔接凹槽126上，进一步地提高加固件17与刷柄12连接的稳固性。其中，熔融连接片152远离固定面122的一侧即为熔接凹槽126的槽底壁，固定面122与熔接凸起124共同熔融形成熔接凹槽126的槽侧壁。
需要说明的是，在本公开中，熔接凸起124高于加固凸起125，且熔接凸起124的顶部距离固定面122的距离的设计范围为0.67mm至0.73mm，可选的，在本公开中，熔接凸起124的顶部距离固定面122的距离为0.7mm。
本公开公开提供的刷头10的工作原理是：
刷柄12上设有相背的刷洗面121和固定面122，或者说，刷洗面121和固定面122分别位于刷柄12相对的两侧。并且，在刷柄12上开设有多个同时贯穿刷洗面121和固定面122的连接通孔123，或者说，连接通孔123由固定面122延伸至刷洗面121。刷毛15穿设于连接通孔123内，刷毛15的部分沿远离刷洗面121的方向凸出于固定面，且刷毛15凸出于固定面122的部分为刷毛熔接部151，在固定连接刷毛15和刷柄12时，通过刷毛熔接部151与固定面122共同熔融连接，以在固定面122上形成覆盖于固定面122的熔融连接片152，也就是说，刷毛熔接部151和固定面122熔接为一体，且熔接的部分还形成一个覆盖于固定面122上的熔融连接片152。通过熔接形成完全覆盖于固定面122的熔融连接片152，使得刷毛15和固定面122的连接处无任何间隙，进而降低残留污渍的几率，更易清理，此外，成片的熔融连接方式使得刷毛15的多根毛体的部分与刷柄12熔融为一体，多根独立的毛体与刷柄12形成一个整体结构，使得刷毛15与刷柄12的连接更加稳固，刷头10不易出现掉毛的情况。
并且，通过设置注塑连接于熔融连接片152上，并覆盖熔融连接片152的加固件17，进一步加固熔融连接片152，既提高了刷毛15连接的可靠性，又能使得熔融连接片152被加固件17完全包裹，加固件17和熔融连接片152 之间未留有间隙，进一步防止水等污渍进入刷头10内部，避免了藏污纳垢，也降低了噪音，且震动效果有明显的改善。
