Provided are an electric handle, an electric toothbrush and an electric cleaning brush. The electric handle comprises a housing, a rear cover, a swing motor and a main control structure. By installing a vibration control mass with limited mass, the rotational inertia of the stator of the swing motor is increased, so that the vibration amplitude of the shell of the swing motor is reduced. It also reduces the vibration amplitude transmitted to the control circuit board, battery and electric handle, decreases the vibration feeling in user's hand, and makes the output shaft of the swing motor transmit effective swing output as much as possible. Then the swing output is transmitted to the toothbrush head or cleaning brush head installed on the output shaft. In this way, the cleaning effect and vibration reduction effect are better, the hand feeling is more comfortable, and the production cost is also reduced.

An electrical brush handpiece, in particular toothbrush handpiece, includes at least one interface for a coupling with a plug-on brush, includes at least one frame unit and includes at least one drive unit for driving the interface which is accommodated in the frame unit, the drive unit including at least one rotor and at least one reset element that is coupled with the rotor with a first end in a rotationally fixed manner and is fixated to the frame unit with a second end in a rotationally fixed manner, wherein the at least one reset element is implemented so as to be plate-shaped.

An oral cleansing device including a handle, a brush head removably connected to the handle at a top end of the handle, a base unit that supports a reservoir to serve as a fluid source, a fluid tube extending from the base unit, and a fluid connector connected to the fluid tube and removably connected to the handle at a bottom end of the hand to connect the handle to the fluid source. The fluid connector includes a magnetic element configured to provide a magnetic attraction to the base unit, thereby assisting in securing the fluid connector to the base unit.

The invention relates to an oral cleaning system (100) for cleaning teeth with a combination of brushing and interdental liquid cleaning. The oral cleaning system (100) comprises a cleaning head (200) as well as a support unit (300) having a fluid reservoir (350) for containing a fluid (110). The cleaning head (200) comprises a brush (240) for brushing the teeth, and an orifice (250) for emitting a part of the fluid (110) for interdental liquid cleaning. A first fluid channel (210) guides the fluid from the fluid reservoir to a hydraulic motor (230) driving the brush (240), and to the orifice (250). The cleaning head (200) further comprises a second fluid channel (220) configured for transporting at least a part of the fluid (110) back from the hydraulic motor (230) to the fluid reservoir (350) of the support unit (300).

A toothbrush or oral cleaning implement including a handle defining a first fluid conduit and a handle inlet port, a brush tip extending from a first end of the handle and defining a second fluid conduit, the second fluid conduit in fluid communication with the first fluid conduit, a brush head supported on an end of the brush tip including a fluid outlet in fluid communication with the second fluid conduit, a handle valve positioned between the handle inlet port and the first fluid conduit, and a base removably connected to the second end of the handle. The base including a base fluid inlet port that connects with an external fluid source, a base fluid outlet port in fluid communication with the base fluid inlet port, and a base valve that selectively opens and closes the base fluid outlet port.

Provided is an automatic control type electric toothbrush, comprising a toothbrush head (20) and a toothbrush handle (10) connected by means of a driving shaft (12), wherein the toothbrush handle (10) is provided with a gesture sensor, a control module and a driving mechanism; and the control module can control the driving mechanism to drive the driving shaft (12), and same also drives the toothbrush head (20) to rotate clockwise or anticlockwise according to gesture data acquired from the gesture sensor, so that the toothbrush head (20) rotates in the direction from teeth root to dental crown. The automatic control type electric toothbrush can realize the purpose of automatically brushing teeth along the teeth, and can protect the gingivae, thus achieving automated treatment without manual control by a user, and therefore improving user experience.

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.

A toothbrush apparatus and system and associated method. The apparatus includes a sensing module that performs at least one of the following: detect at least one time period associated with use of the toothbrush apparatus, detect one or more movements of the toothbrush apparatus, and any combination thereof. The apparatus's one or more processors communicatively coupled to the sensing module determine one or more measurements based on at least one of: the detected time periods, the detected movements, and any combination thereof, and store the determined measurements in one or more memory locations communicatively coupled to the processors. The apparatus also includes one or more feedback modules that receive the stored measurements and encode the measurements into corresponding feedback signals. One or more data transfer modules transmit the feedback signals.

A brush head for an oral cleansing device is provided. The brush head may include a shaft and a cantilevered beam positioned within the shaft. The cantilevered beam may be configured to press against a drive shaft of the oral cleansing device to transfer motion of the drive shaft to the brush head. The cantilevered beam may be formed on an adapter secured within the shaft.

The brush head of the toothbrush has filaments that are pointed at one end and led through clearances in the bristle carrier. These filaments have a length of about 10-20 mm. The tips of the pointed filaments produce a height profile other than that of a plane and the ends of the pointed filaments that are remote from the tips are melted.
