  • Brushes with interchangeable heads
    Patent number: 8371313
    Abstract: One embodiment of a head-switchable brush comprises a brush head, a ferrule, and a brush handle. The ferrule has the head at one end and the handle at the other end. There is a piece of magnet attached to the brush handle and ferrule respectively where the two parts connect. The brush head can be switched and assembled with the handle easily whenever needed. The ferrule can be kept firmly on the handle by the action of the magnet inside. The head-switchable function of this brush kit can greatly enlarge the brush applying space and also avoid the material wasting since this brush kit has one handle only but with various brush heads.

  • Brushes with retractable removable heads
    Patent number: 8132285
    Abstract: One embodiment of an applicator comprises a brush head with a ferrule, and a brush handle. The ferrule has the head at one end and the handle at the other end. Magnetic elements, at least one of which is a magnet, are attached to the brush handle and ferrule where the two parts connect. The brush head can be removed from the handle, assembled with the handle, and switched easily whenever needed. The ferrule can be kept firmly on the handle by the action of the magnet inside. The head can be retracted by sliding a sleeve mounted on the handle forward over the sides of the head. The head, when removed from the handle, can be washed without the risk of water penetrating the sleeve mechanism.
