Abstract: A light bulb includes a base and a top portion is connected to the base. A control circuit is installed within the top portion and is connected with the base. A board is connected to the top portion and a first LED is connected to the center thereof. Multiple second LEDs are connected to the board and located around the first LED. The first LED and the second LEDs generate different colors. The control circuit controls the first LED and the second LEDs to be activated separately or simultaneously. A globe is connected to the top portion and accommodates the first LED and the second LEDs. The light bulb emits a single color or different colors simultaneously.

Abstract: An insole has a configuration corresponding to either one of human feet, the insole having five toe recesses defined therein near a front end of the insole, each one of the toe recesses having a first boss extending from a bottom defining the toe recess, a first arch protrusion extending from the insole near the toe recesses and a central protrusion extending from a mediate portion of the insole, a rear end plan area defined near an rear end of the insole and a side protrusion extending from an inner side of the insole, each of the first arch protrusion and the central protrusion having at least one magnetic element received therein, the plan area having a protrusion extending therefrom in which a third recess is defined for an other magnetic element being received therein, a fourth recess defined in the insole near an outer side of the insole and yet another magnetic element being received in the fourth recess, the insole having a plurality of tiny bosses extending upwardly from the rest area of the insole a

Abstract: A filtering module includes a housing consisting of an upper housing section and a lower housing section and a connecting member for connecting the upper and lower housing sections. The upper housing section has a first water port in a first end thereof and a pair of substantially L-shaped recesses in a second end thereof. The lower housing section has a second water port in a first end thereof and a second pair of substantially L-shaped recesses in a second end thereof. The connecting member includes a filtering mesh and two pairs of L-shaped protrusions formed on an outer periphery thereof to be fittingly received in associated L-shaped recesses.
