A foaming device comprises a valve body, a pump, and a self-suction spray head. The valve body comprises a water inlet port, a liquid inlet port, a mixing cavity, and a liquid outlet port. Each of the water inlet port, the liquid inlet port, and the liquid outlet port is in communication with the mixing cavity, and an input end of the pump is connected to the liquid outlet port to enable the mixing cavity to generate a negative pressure to suck water and foaming agent respectively from the water inlet port and the liquid inlet port for mixing. The self-suction spray head is connected to an output end of the pump, and the self-suction spray head comprises a first air inlet hole and a spray hole to enable mixed liquid to be mixed with air to produce foam to be sprayed out.

Provided is a portable IPL sterilizer comprising: a body partitioned into a central region and a peripheral region surrounding at least a portion of the central region; a xenon lamp light source for sterilization provided in the central region of the body; and a light-shielding comb part provided in the peripheral region of the body.

A chemical feeding device according to the present invention is for attaching to a water tank of a toilet having a tank main body that has an opening is an upper portion and a lid body that covers the opening of the tank main body, the chemical feeding device including a chemical container storing a chemical solution, a flexible tube through which the chemical solution in the chemical container is fed to the water tank, and an attachment member that supports the tube and is configured to be attachable to an edge of the upper opening of the tank main body. The attachment member has a disposition part that is where the tube is disposed and that guides the tube into the water tank, and the disposition part is formed by at least one of a straight part and a curved part so as to not have a corner.

A urine deflector is configured to attach to a toilet seat and is made of a monolithic structure comprising an arcuate top member having a planar top surface integrally formed with an arc shaped projecting portion, the arc shaped projecting portion projecting downwardly from the top member, the projecting portion integrally formed, at each end of the arc shape, with a gravity assist drain portion, each gravity assist drain portion extending from the projecting portion at an angle from 30° to 60° from a plane defined by a top surface of the top member that facilitates directing urine liquid into a toilet bowl when the toilet seat is in either a seated position or an open position.
