Pent type travel toothbrush

Abstract

The invention provides a pen type travel toothbrush. A cavity is formed in a brush handle of the toothbrush and is filled with toothpaste; the cavity is communicated with a one-way valve on the upper part of the brush handle, and bristles are distributed at the periphery of the one-way valve; a piston is arranged in the cavity, and the toothpaste in the cavity is squeezed out of the one-way valve by compressing the piston; the upper part of the brush handle is provided with a screw thread or a bell and spigot joint used for communicating the cavity with the external space; when the screw thread or the bell and spigot joint is opened, the piston is pulled to repeatedly pump the toothpast at the screw thread or the bell and spigot joint into the cavity. As the one-way valve is used, the toothpaste which is not used in the cavity of the brush handle cannot be polluted. The pen type travel toothbrush is convenient and quick in use, and a toothpaste lid covers the pen type travel toothbrush when the pen type travel toothbrush is not used, so that the pen type travel toothbrush is convenient to carry.
本发明提供一种笔式旅行牙刷,牙刷刷柄内设有空腔,空腔内填充牙膏;空腔与刷柄上部的单阀门连通,单向阀周围分布刷毛;空腔内设有活塞,通过压缩活塞将空腔内牙膏从单向阀中挤出;刷柄上部设有丝扣或承插口,用于空腔与外部空间连通,当打开丝扣或承插口时,拉动活塞可将丝扣或承插口部位的牙膏反复抽入牙膏。因为使用单向阀,刷牙时不会污染刷柄空腔内未使用的牙膏。使用时方便快捷,不用时盖上牙膏盖,便于携带。
