A method for oral care. In one aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect motion of an oral care device during a brushing routine of a user, the sensor data corresponding to the detected motion; and b) determining a target brushing time based on the sensor data. In another aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect brushing intensity during a brushing routine of a user, the sensor data corresponding to the detected brushing intensity; and b) determining a target brushing time based on the sensor data.

There is provided a controller for a fluid-detection system, wherein the controller is configured to: determine if a user is interacting with the fluid detection system, wherein the determining comprises at least one of: determining whether a user is within a predetermined distance of the fluid detection system; determining whether a user is in physical contact with the fluid detection system; determining whether a fluid sensor of the fluid detection system is in a mouth of a user; and control the temperature of the fluid sensor of the fluid detection system based on the result of the determination. There is also provided a fluid based detection system comprising the controller, a device comprising the controller, a remote device comprising the controller, and a computer implemented method for controlling a fluid detection system, the method comprising the steps of: determining if a user is interacting with the fluid detection system, wherein the determining comprises at least one of: determining whether a user is within a predetermined distance of the system; determining whether a user is in physical contact with the fluid detection system; determining whether a fluid sensor of the fluid detection system is in a mouth of a user; and controlling the temperature of the fluid sensor of the fluid detection system based on the result of the determination.

Provided is a brush head for an oral cleaning device for cleaning teeth with a combination of brushing and emitting of a cleaning agent. The brush head comprises a bristle set for brushing the teeth and a nozzle for emitting the cleaning agent. When actuating the bristle set from a first configuration, which is optimized for brushing, to a second configuration, which is optimized for emitting of a cleaning agent, at least a part of the bristle 5 set is moved away from the nozzle and/or away from a path of the cleaning agent when being emitted from an orifice of the nozzle.

An electric toothbrushing device is disclosed, the device comprising means (16) for producing vibration of a toothbrush head (14), means (24, 32, 40, 42, 44) for producing an orientation signal indicating of an area of the mouth being brushed, and means (47, 48, 49) for producing a pressure signal indicating a pressure applied to the toothbrush head. The device further comprises processing means (46) arranged to link values of the orientation signal with values of the pressure signal in order to provide feedback to a user regarding a brushing pressure applied to each of a plurality of different areas of the mouth. By linking values of the orientation signal with values of the pressure signal, the user can be better informed about which parts of the mouth are being or have been brushed too hard. This can help the user to correct their brushing technique.

Provided are a washing device, a control method thereof and a smart home apparatus. The washing device includes a support plate, a charging cup, a liquid feeder and a power supply management system. A top surface of the support plate is provided with a first charging stand. The heating member can be electrically connected to the first charging stand. The liquid feeder is provided with a fluid inlet, a fluid outlet and an on-off switch. The power supply management system is connected to and controls the first charging stand and the on-off switch, the power supply management system receives a start-up instruction, controls the on-off switch to be turned on according to the start-up instruction to supply liquid to the charging cup, and controls the first charging stand to be electrified according to the start-up instruction to heat the liquid in the charging cup through the heating member.

Provided are a toothbrush sterilizing assembly and an electric toothbrush. The toothbrush sterilizing assembly includes a sterilizing shell, a sterilizing cover, a sterilizing element, a control module and a power supply module. The sterilizing shell has a cylindrical shape and is sleeved outside an electric toothbrush. The sterilizing cover is detachably connected to one end of the sterilizing shell and is capable of covering the one end of the sterilizing shell. The sterilizing element is disposed on an inner wall of the one end of the sterilizing shell. The control module is connected to the sterilizing element and configured to control the sterilizing element to start to sterilize a brush head of the electric toothbrush. The power supply module is electrically connected to the control module.
