A brushing device including a motor having an eccentric drive shaft, an output shaft operably connected to the motor, and a power train assembly coupled between the eccentric drive shaft and the output shaft. The power train converts rotation of the eccentric drive shaft into an oscillating movement of the output shaft. The power train includes one or more conservation features that absorb energy when the output shaft rotates in a first direction and reapply energy to the output shaft when it rotates in a second direction.

Oral cleansing device with energy conservation

Disclosed is a multi-functional visual electric toothbrush, including a main unit, an oral viewer, an interdental cleaning appliance and an electric toothbrush head. The oral viewer is connected to the main unit, the interdental cleaning appliance is connected to the front end of the oral viewer, and the electric toothbrush head is connected to a toothbrush driving mechanism. A circuit system and a control system of the main unit can not only transfer the energy of a power supply to the toothbrush driving mechanism, so as to drive the electric toothbrush head to work for large-area oral cleaning, but also connect a lighting system, an observation system and a switch of the oral viewer to control the oral viewer to work. The interdental cleaning appliance may be used cooperatively with the oral viewer to perform targeted cleaning on difficult-to-clean food debris in an oral cavity.

The invention discloses a control method of an electric toothbrush. The electric toothbrush comprises a pressure sensor, a deformation resistor and a control board. The control method comprises the following steps that the electric toothbrush is controlled by the control board to enter an awakening state; after the electric toothbrush enters the awakening state, when the deformation produced by ahousing of the electric toothbrush is detected by the deformation resistor, a deformation signal is transmitted, and the electric toothbrush is controlled by the control board to switch modes; when pressure information stressed on a toothbrush head is detected by the pressure sensor, a pressure signal is transmitted, a driving motor in the electric toothbrush is controlled by the control board tobe started, and the electric toothbrush enters a tooth brushing state; and after the tooth brushing state is entered, if the situation that the pressure information stressed by the toothbrush head isan initial pressure value is detected by the pressure sensor, the driving motor is controlled by the control board to be switched off, and the electric toothbrush enters the awakening state. Through the adoption of the control method disclosed by the invention, functions of non-key automatic awakening, automatic starting and automatic mode switching of the electric toothbrush can be realized.

Handle for dental appliance

A dental cleaning appliance includes a handle, and a cleaning tool detachably connected to the handle. The cleaning tool includes a nozzle for delivering a burst of working fluid to the teeth of a user, a stem extending between the handle and the nozzle, and a fluid reservoir for storing working fluid. The fluid reservoir is detachably connected to, and extends around, the stem. The stem is detachable from the handle separately from the fluid reservoir. The fluid reservoir may be detached from the stem following the detachment of the cleaning tool from the handle, or detached from the handle following the detachment of the stem from the handle.

Dental cleaning appliance

The present disclosure relates to an oral cleansing device with illumination features. In one example, the device includes a housing including an aperture, such as a button aperture, defined therethrough, a diffuser connected to the housing and configured to span over the aperture. The device also includes a blocking member positioned over a portion of the diffuser and connected thereto and a lighting array received within the housing and at least partially aligned with the blocking member such that light emitted from the lighting array is transmitted to an exterior of the housing by traveling around the blocking member and through the diffuser.

Brushing device with illumination features

The present disclosure relates to an oral cleansing device with illumination features. In one example, a diffuser for diffusing light is disclosed. The diffuser includes a first membrane configured to be positioned over a first light source, a second membrane coupled to the first membrane and configured to be positioned over a second light source; and a bridge coupling the first membrane to the second membrane, where the bridge extends from an edge of the first membrane to an edge of the second membrane in an indirect manner.
