Abstract

The invention discloses a rotary connecting device for rotating shaft home appliances, which comprises a motor output shaft (6), a carrier driving shaft (7) driving a carrier to rotate, a permanent magnet rotor (1) and a tubular metal conductor (3), wherein the permanent magnet rotor (1) is fixedly connected to the motor output shaft (6); the tubular metal conductor (3) is fixedly connected to the carrier driving shaft (7); the permanent magnet rotor (1) is positioned in the tubular metal conductor (3), and the permanent magnet rotor (1) and the tubular metal conductor (3) can rotate relative to each other; a gap is reserved between the side wall of the permanent magnet rotor (1) and the inner wall of the tubular metal conductor (3); and a gap is reserved between the top end of the permanent magnet rotor (1) and the tube bottom of the tubular metal conductor (3). The power input shaft and the power output shaft transmit the torque under the mutual action of magnetic fields; and mechanical connection is not present between the input shaft and the output shaft, so the rotary connecting device can avoid abrasion and has small vibration.

Description

technical field [0001] The invention relates to a connection device, in particular to a rotary connection device for small household appliances of the rotating shaft type. Background technique [0002] Existing small household appliances, such as food processors and other rotating small household appliances that require couplings, work on the basis that the motor drives the carrier to rotate, thereby completing functions such as stirring and grinding. The motor and the driving carrier are connected through rigid or Flexible coupling connection. [0003] For example, for cooking machines, the motor and the drive carrier are connected by two rubber or plastic half-couplings, which are flexible couplings whose structure is tooth-shaped embedded, and one of the half-couplings is connected to the motor , the other half-coupling is connected to the drive carrier. like figure 1 , figure 2 As shown in the figure, the half-coupling connected with the motor is evenly distributed ...
