非接触式电力传输装置
摘要：
一种非接触式电力传输装置(1)，其配备有：盥洗台(10)，其包括初级线圈(24)；以及电动牙刷(30)，其包括次级线圈(41)、整流电路(42)和供电控制部(43)。电动牙刷(30)包括：第一辅助线圈(45)，用于中继从初级线圈(24)流向次级线圈(41)的磁通量；以及第二辅助线圈(47)，用于中继从初级线圈(24)流向次级线圈(41)的磁通量。第二辅助线圈(47)的中心轴(J12)与第一辅助线圈(45)的中心轴(J11)正交。
摘要（英）：

A contactless power transmission device (1) is provided with: a washstand (10) that includes a primary coil (24); and an electric toothbrush (30) that includes a secondary coil (41), a rectifier circuit (42), and a feed control unit (43). The electric toothbrush (30) includes a first auxiliary coil (45) which relays a magnetic flux which flows from the primary coil (24) to the secondary coil (41), and a second auxiliary coil (47) which relays a magnetic flux which flows from the primary coil (24) to the secondary coil (41). A central axis (J12) of the second auxiliary coil (47) is perpendicular to a central axis (J11) of the first auxiliary coil (45).
