  • Publication number: 20150289958
    Abstract: The transmission according to the invention for an electric toothbrush serves for the transmission and reforming of a rotational movement provided by an electric motor into a particularly careful and effective cleaning movement of a cleaning element. The ratio of the distance between the longitudinal mid-axis of an output shaft and the longitudinal mid-axis of a drive shaft of the transmission and of the distance between the longitudinal mid-axis of a shaft driving a cam of the transmission and the longitudinal mid-axis of the cam amounts to at least 10:1.

  • Patent number: 9126346
    Abstract: The inventive body care device having a handle and a treatment head, which is hingedly connected mechanically therewith, has a flexible zone for enabling an elastic deflection of the treatment head with respect to the handle and a deflection sensor, which is capable of generating an electric signal as a function of the elastic deflection. This signal can be used to control an automatic start and/or stop function, a use counter and/or operating states of an electric vibrational element integrated in the body care device.

  • Patent number: 8973202
    Abstract: The oral hygiene device, particularly a toothbrush, has in the neck part, a cavity, which is closed off from the surroundings and in which a snap dome is arranged. This snap dome produces an acoustic warning signal when a limiting bending of the neck part is exceeded as a result of a limiting pressing force with which the head part is pressed, for example, against the teeth and gums is exceeded. On the one hand, this has the effect of protecting the snap dome, usually produced from metal, from corrosion and, on the other hand, the cavity serves as a resonance chamber to amplify the warning signal.

  • Publication number: 20150037204
    Abstract: Methods and devices for gas sterilization are described, in which products are sterilized using a sterilization gas. Process gases are mixed in a mixer without movable parts before being introduced into the sterilization chamber in order to obtain a homogenous gas mixture. A device for the gas sterilization of products comprises a mixer without movable parts and a sterilization chamber. The sterilization chamber has at least one inlet opening and at least one outlet opening. The mixer is arranged such that it is connected via a first line, which leads into a first opening in the mixer without movable parts, with the at least one outlet opening of the sterilization chamber and is connected via a second line, which leads into a second opening in the mixer without movable parts, with the at least one inlet opening of the sterilization chamber. A third gas supplying line leads into a third opening in the mixer.

  • Publication number: 20140237744
    Abstract: A toothbrush has a removable end cap at its free end area directed away from the bristles, which end cap closes off an inner space of a grip element. The end cap accommodates an electrical control element, in particular a potentiometer, which can be adjusted via an adjustment element arranged rotatably on the end cap. The toothbrush also comprises an electrical power consumption unit, in particular an electric motor, which is designed to set the bristles in vibration. The energy supply from an energy reservoir arranged in the interior to the electrical power consumption unit can be adjusted continuously by means of the control element, as a result of which the vibration intensity of the bristles can be steplessly adjusted.

  • Publication number: 20140082866
    Abstract: 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.

  • Patent number: 8327490
    Abstract: An interdental treatment device, such as a toothbrush, includes a handle configured to accommodate an electric power source, a head carrying an interdental treatment tool, and a neck between the handle and the head. The head or neck includes a mechanical motorized vibratory device, including a drive which causes the head to vibrate. Electrical connections are operably connected to the mechanical vibratory device and the electric power source to power the mechanical vibratory device via the electrical connections. In various embodiments, a switch may be operably connected to at least one of the electrical connections to interrupt power from the power source to the mechanical motorized vibratory device. In various embodiments, a vibration-damping structure dampens vibration transmission from the head to the handle.
