  • Patent number: 7150285
    Abstract: A cleaning device for a hair removing apparatus such as a dry shaver has a basin that receives a shaver head and is supplied with a cleaning liquid for cleaning the head. A single pump is utilized for supplying the liquid from a tank to the basin. The tank is hermetically sealed and is selectively open to the atmosphere by way of an air valve. The valve and the pump are actuated in a controlled manner to selectively give a supply mode for supplying the liquid to the basin from the tank and a recovery mode for recovering the liquid from the basin to the tank.

  • Publication number: 20060162749
    Abstract: A cleaning device has a basin that receives an operator head of the hair removing apparatus, a tank storing a volume of a cleaning liquid, and a pump supplying the liquid from the tank to the basin for cleaning the operator head. A drip pan is formed separately from the tank and is disposed underneath the basin for collecting the liquid dripping from the basin as well as contaminants dislodged from the operator head. The drip pan is connected to the tank so as to return the liquid from within the drip pan to the tank under the action of the pump. A filter is provided in the drip pan for removing the contaminants from the liquid so that the filter can be cleaned or replaced without involving the tank and the liquid contained therein.

  • Publication number: 20060011225
    Abstract: A cleaning system for cleaning an operator head of a hair removing apparatus such as a dry shaver. The system includes a cleaning device having a housing configured to hold the shaver upside down to place the operator head in a basin for cleaning the same with a liquid supplied from a tank. The apparatus incorporates an externally controllable electric circuit for driving the operator head in accordance with an external electric signal generated by a controller within the device. The device's housing has a signal transmitting means for transmitting the electric signal, while the apparatus has a signal receiving means which comes into electrical interconnection with the signal transmitting means. The signal receiving means is disposed intermediate the height of the apparatus such that the electrical interconnection can be made within the height of the apparatus, requiring no extra height dimension to the system for the electrical interconnection.

  • Publication number: 20050274402
    Abstract: A cleaning device for an electrical hair removing apparatus is capable of being stored in a compact profile. The apparatus has an operator head at its top, and is formed on its bottom with an electric terminal for receiving an external signal that controls the apparatus. The cleaning device includes a basin for receiving the operator head of the apparatus and also includes a control circuit providing the external signal. The device has a tank storing a volume of a cleaning liquid, and a circulator configured to supply the cleaning liquid into the basin from the tank for cleaning the operator head. A stand is provided on the device to hold the apparatus upside down with the operator head disposed within the basin. The stand is formed at its top end with a header carrying contacts which are connected to the terminal on the bottom of the apparatus. The stand is composed of a fixed support and a movable arm which extends from the support and is formed at its top with the header.

  • Publication number: 20050189003
    Abstract: A cleaning device utilizes a cleaning liquid composed of a solute dissolved in a solution for cleaning an operator head of a hair removing apparatus. The device includes a housing configured to hold the hair removing apparatus, a basin mounted in the housing for receiving therein the operator head, and a tank storing the solution or the liquid. A circulator is provided to circulate the cleaning liquid between the tank and the basin. The device includes a container which is configured to hold the solute and is formed separately from the tank. The container is disposed in a circulation path between the basin and the tank in order to replenish the solute into the circulating solution or the liquid. Thus, the solute can be constantly supplied to the solution or the cleaning liquid for maintaining the cleaning effect over a prolonged period of use and for easy replenishment of the solute, eliminating the necessity of replacing the whole cleaning liquid.
