Abstract

The invention relates to a preferably electric toothbrush comprising a handpiece and a detachable toothbrush head. In particular, the invention relates to the toothbrush head of the toothbrush, which head comprises a bristle field and a coupling device for coupling it to the handpiece of the toothbrush. A line for supplying a pasty, gel-type and / or liquid substance to be applied, especially toothpaste, is provided on the toothbrush head. The coupling device has a line coupling for coupling the line to a line section on the handpiece. The invention also relates to the handpiece of such a toothbrush, comprising a coupling device for coupling it to the toothbrush head. The handpiece also has a line for supplying a pasty, gel-type and / or liquid substance to be applied, especially toothpaste.;The coupling device has a line coupling for coupling the line on the handpiece side to the line on the brush head side. The line coupling comprises a control valve which is opened by the action of a valve actuator when the toothbrush head is coupled to the handpiece of the toothbrush and which links a line section on the handpiece side to a line section on the brush head side and closes the line when the brush head is decoupled from the handpiece.
