The present invention discloses a deburring brush, comprising a pressing plate, jacking posts, copper sleeves, gaskets, guide posts, springs and bristle units. When the bristle units need replacement, it only needs to place the deburring brush on the ground and then press down edges of the front side of a top plate, so that all the bristle units will fall off against the suction force of strong magnets under the action of each jacking post. According to the present invention, it avoids being time consuming and labor intensive due to removing the bristle units one by one by using a screw driver or other similar devices while replacing the bristle units, and at the same time the replacing speed of bristles is greatly increased.

Disclosed is a new method, and a system, for increasing the pH of a composition applied on teeth and/or gums. The composition is gelable under the influence of a pH change. The pH change typically is a pH increase in the event of a direct pH-triggered gelation. The pH change typically is a pH decrease in the event of gelation induced by ions, such as calcium ions, released from a pH-sensitive carrier. The device comprises a dispensing unit for the composition, a distal end of which is adapted to apply said substance onto teeth or gums. The device further comprises an electrode system comprising first and second electrodes, the first electrode being adapted to be held against the composition at a location at or near teeth or gums, and the second electrode being adapted to be held against the composition at a location away from teeth or gums, The electrode system is adapted so as to provide an electrical potential difference of 1.5 to 10 Volt between the electrodes.

A toothbrush having a detachable head portion is provided. The toothbrush includes a handle portion, a neck portion, and a head portion, and the head portion includes a first head portion and second head portion. The second head portion is detachable from the first head portion. The toothbrush further includes a button portion and an attachment/release mechanism. The button portion is actuatable to actuate the attachment/release mechanism to facilitate detachment of the second head portion from the first head portion.

A removable brush head for a personal groom device, the removable brush head having a stationary portion, wherein the stationary portion is annular and includes a plurality of outwardly-extending brush bristles. The removable brush head also includes a movable portion positioned within the stationary portion, wherein the movable portion is configured to at least partially rotate relative to the stationary portion, and further wherein the movable portion includes a plurality of outwardly-extending brush bristles. Additionally, the removable brush head includes a locking collar, wherein the locking collar is slidably couplable to the stationary portion so as to axially retain the movable portion within the stationary portion while allowing the movable portion to at least partially rotate relative to the stationary portion.

A gutter broom is provided. The gutter broom can include a mandrel, one or more carriers, each carrier removably coupled to the mandrel, and one or more bristle strips, each bristle strip removably coupled to one of the carriers. The gutter broom components can be recyclable and modular, requiring no tools for assembly or servicing.

A paintbrush with adjustable bristle width, length, angle and/or shape that allows the user to configure the shape of the application surface as desired, thus eliminating the need for painters to utilize multiple traditional paintbrushes with different bristle configurations for different size and shaped surfaces being painted. The invention includes multiple bristle pack segments, elongated guideways, finger adjustment knobs, finger knob slide slots, and a brush slide body housing wherein the mechanisms for adjusting the length of the individual bristle pack segments are contained; is scalable, wherein different overall sizes and widths of paintbrushes can be manufactured which retain the unique adjustability of the invention; can be manufactured with or without a handle, allowing the invention to utilize a wide variety of handles of various materials, sizes and shapes which can be affixed to the bristle slide body housing; is not limited to a specific number of bristle pack segments, elongated guideways and finger knob slide slots; is not limited to specific sized bristle pack segments, elongated guideways and finger knob slide slots; is suitable for manufacturing using various materials; is siutabe for manufacturing utilizing various bristle materials (e.g., Black China, White China, Ox Hair, synthetic materials, etc.); may be modified for use with a self-feeding paint mechanism; is not limited to the purpose of applying paint; is suitable for applying coatings including paint; may be manufactured in various colors; may be manufactured using various graphics.

This invention relates to a device (1) for performing personal care operations on a subject. The device (1) comprises a handheld base body (3), a driving unit (400) to receive and drive an interchangeable treatment head (2) to perform the personal care operation, a sensor (7) for measuring the amount of current drawn from a motor arrangement (5, 6) while the driving unit (400) is being operated. The device (1) further comprises a control unit (8) operably connected to the sensor (7) and the driving unit (400) and configured to control the driving unit (400). The control unit (8) is configured to identify the individual treatment head (2) fitted on the driving unit (400) by comparing the measured motor current at the predefined measuring time (t1) with at least one predefined current threshold (C).
