The invention provides a multifunctional induction pull head. The multifunctional induction pull head comprises a pull head seat body with a water inlet cavity, a flow channel switching assembly installed in the water inlet cavity and a water outlet spray head fixedly connected with the pull head seat body. A main water flow channel and a standby water flow channel are arranged in the pull head seat body; the flow channel switching assembly comprises a first precision ceramic piece and a second precision ceramic piece tightly attached to the first precision ceramic piece; the second precision ceramic piece is provided with a main water outlet hole communicated with the water inlet end of the main water flow channel and a standby water outlet hole communicated with the water inlet end of the standby water flow channel; the first precision ceramic piece is provided with a first water inlet hole selectively communicated with one of the main water outlet hole and the standby water outlet hole in a rotating mode; and a control valve for controlling the main water flow channel to be blocked or communicated is arranged on the pull head seat body. According to the multifunctional induction pull head, normal water outlet can be ensured under the condition that the control valve fails, so that great convenience is brought to actual use, meanwhile, the service life of the pull head is prolonged, and the replacement frequency of the pull head is reduced.
本发明提供一种多功能感应抽拉头，包括形成有进水腔室的拉头座体、安装于进水腔室内的流道切换组件、固定连接拉头座体的出水喷头；拉头座体内具有主用水流道和备用水流道；流道切换组件包括第一精密陶瓷片以及与第一精密陶瓷片紧密贴合的第二精密陶瓷片；第二精密陶瓷片具有与主用水流道的进水端相连通的主出水孔和与备用水流道的进水端相连通的备用出水孔；第一精密陶瓷片具有通过旋转方式选择连通主出水孔和备用出水孔二者之一的第一进水孔；拉头座体上设有控制主用水流道阻断或连通的控制阀。本发明可以保证在控制阀失效的情况下也能够正常出水，这为实际的使用带来了极大的方便，同时有助于延长抽拉头的使用寿命，降低抽拉头的更换频率。
