    • A toothbrush includes a handle and a head mounted to the handle. The head may generally include a membrane attached to it and configured for attachment to a cleaning element. The membrane may be generally dome shaped and may be resiliently flexible when a brushing force is applied. A plurality of cleaning elements is mounted to the membrane. The cleaning elements may be attached using anchor free tufting. In addition, the cleaning elements may be sufficiently spaced so as to allow separation of the melted portion of the cleaning elements. In another arrangement, the head may also include walls or dams positioned between the cleaning elements. The walls prevent the melted portion of the cleaning elements from merging with the melted portion of another cleaning element. This isolation of the molten nylon allows the cleaning elements to move independently of each other.
    • 牙刷包括手柄和安装在手柄上的头部。 头部通常可以包括附接到其上并被配置为附接到清洁元件的膜。 膜可以是大致圆顶形的,并且当施加刷牙力时可以是弹性柔性的。 多个清洁元件安装在膜上。 清洁元件可以使用无锚定的簇绒连接。 此外,清洁元件可以被充分间隔开,以便分离清洁元件的熔化部分。 在另一种布置中,头部还可以包括定位在清洁元件之间的壁或水坝。 这些壁防止清洁元件的熔化部分与另一个清洁元件的熔化部分合并。 熔融尼龙的这种隔离允许清洁元件彼此独立地移动。
