Abstract: A personal hygiene device has a handle and a treatment head pivotably connected with the handle. Applying a treatment force against the treatment head causes a pivoting of the treatment head relative to the handle. A sensor, such as, e.g., a Hall sensor, fixedly secured with respect to one of the handle and the treatment head, measures a measurement variable. A sensor cooperation unit defines or influences the measurement variable in dependence on the relative position of the sensor and the sensor cooperation unit, such e.g., as a sensor permanent magnet, fixedly secured relative to one of the handle and the treatment head. A spring unit defines a rest position of the treatment head when no treatment force is applied. The spring unit has a first spring constant in the treatment direction and a second spring constant in a lateral direction, the second spring constant being at least about two times higher than the first spring constant.

Abstract: An electric toothbrush replacement head device is provided, including a brush head portion, which is provided with a toothbrush handle and a toothbrush head. A rotating cover is disposed adjacent to an end of the brush head portion. A vibration assembly is disposed in the rotating cover, and includes a first fixed plate, a size of which corresponds to an inner diameter of the rotating cover. The first fixed plate is provided with a space-keeping slot therein, a square shaft thereof, and a connecting seat thereon. An end of the square shaft is connected to the brush head potion through the space-keeping slot. An opposite end of the square shaft is connected to the connecting seat. The device is designed with a simple structure, which is flexible for installation and disassembly, and more convenient for use, furthermore, improves transmission efficiency and possesses various functions.

Abstract: An oral care device having a head with cleaning elements and a handle coupled to the head. The handle may include a selectively rotatable ring arranged between the head and a distal end of the handle that is configured to allow a user to select a desired mode of operation of the oral care device. The handle may include a selectively illuminated light that is configured to display at least one color that visually indicates that certain behaviors, patterns, and/or consistent habits have been performed successfully. The handle may include a processor configured to track a duration of a user's brushing session, a light ring on a bottom surface of the handle, and a pressure sensor. Respective portions of the light ring may be selectively illuminated by the processor to visualize progress toward achieving a predetermined brushing routine time and/or to visualize an over-pressure condition sensed by the pressure sensor.

Abstract: An electric brush powered by mains electricity includes a power converter, an upper housing, a lower housing, a push button switch, an electric motor, a speed reducer, an output rotation shaft, an adapter, a brush head and a seal ring. The speed reducer and the electric motor of a mechanical rotation part, and the push button switch and a low-voltage power socket of a circuit part are all mounted in an airtight housing inner cavity. Meanwhile, the brush head and a main body part are in a plugged-in connection. The brush head can be randomly changed to realise multiple purposes, so that the defects of the poor waterproofing performance and the single function of existing electric brushes can be thoroughly solved, thereby greatly improving the reliability and the convenience of the product.

Abstract: An adjustable circuit for a personal electric cleaning care appliance comprises comprising a power supply portion and a driver is disclosed. The driver comprises a transducer, a drive coil and an iron core of the drive coil, and a drive shaft of the transducer is equipped with cleaning elements. The adjustable circuit comprises a microchip processor and an H-bridge drive circuit. By connecting a capacitor bank and the drive coil in series at load ends of the H-bridge drive circuit, at least a part of the capacitors of the capacitor bank is controllably connected in series with the drive coil or disconnected from the drive coil, the capacitance of the connected capacitor can be controlled so that the current flowing through the drive coil is controllably limited to a certain value, thereby, the motion amplitude of the cleaning elements can be controlled, and no additional electromagnetic interference will occur.
