    • The invention relates to a small electrical appliance, for example an electric toothbrush (1), with two elements to be driven and with an electric motor (10). The small electrical appliance has a device (16.1; 16.2; 16.3) that drives the first and/or the second element depending on the direction of rotation of the electric motor (10). The first element to be driven can be a movable brush head (2), and the second element to be driven can be a pump (7, 14) for conveying a care agent to the brush head (2) from a reservoir, wherein the device (16.1, 16.2, 16.3) drives the brush head (2) in both directions of rotation of the electric motor (10), but drives the pump (7, 14) only in one direction of rotation of the electric motor (10). If the electric toothbrush (1) has a brush head (2) and first and second reservoirs (6, 13) for two different care agents, the first reservoir (6) is connected via a first pump (7) to a first channel (8) and the second reservoir (13) is connected via a second pump (14) to a second channel (15), these channels opening into the brush head (2). The first and/or second pump (7, 14) can alternately be driven from the electric motor (10), by means of a device (16/1; 16.2; 16.3), depending on the direction of rotation of the electric motor (10).
    • 本发明涉及一种小型电器,例如电动牙刷(1),具有两个驱动元件和电动马达(10)。 小型电器具有根据电动机(10)的旋转方向驱动第一和/或第二元件的装置(16.1; 16.2; 16.3)。 待驱动的第一元件可以是可动刷头(2),并且待驱动的第二元件可以是用于从储存器将护理剂输送到刷头(2)的泵(7,14),其中 装置(16.1,16.2,16.3)在电动机(10)的两个旋转方向上驱动刷头(2),但仅在电动机(10)的一个旋转方向驱动泵(7,14) 。 如果电动牙刷(1)具有用于两种不同护理剂的刷头(2)和第一和第二储存器(6,13),则第一储存器(6)经由第一泵(7)连接到第一通道 8),并且第二储存器(13)经由第二泵(14)连接到第二通道(15),这些通道通向刷头(2)。 根据电动机的旋转方向,第一和/或第二泵(7,14)可以通过装置(16/1; 16.2; 16.3)从电动马达(10)交替驱动, 10)。
