Abstract: A multi-function shower head comprising a shower head body mounted at the upper end of a grip and several units for making bubbles, message, scrubbing, etc. passible to be selectably and additionally attached on the shower head body. The shower head body is provided with three water passages to be selectably connected with a tubular water passage in the grip for water to run out of many small holes in the outer surface of the shower head body. The grip also has a tubular passage for soap solution and a tubular passage for a wire rope to fit in and rotated by a motor so as to rotate a cylindrical shaft used for combining any of the several extra units for different purposes of bathing.

Abstract: A automatic air pump for car wheel tires, especially those without tubes, utilizes an air piston with a cylinder fixed on a rim which enables its piston plate to contact and be pushed by the interior tire surface successively by the wheel rotation compressing air into the tire chamber until the pressure grows sufficient and the piston rod no longer touches the interior tire surface. If a static wheel is also desired to be pumped full of air automatically, a compressor and a pressure-gauge piston can be added. When the tire pressure grows insufficient, the compressor can be started by detaching a metallic plate from two metallic projections caused by the interaction of the piston rod and the interior tire and air is sucked into the cylinder and flows into the tire chamber sufficiently. Then a piston plate of a pressure-gauge piston is lifted up making an electric connection to cut the electricity from the compressor and the piston rod recovers its original position.

Abstract: A coffee maker comprising a main housing separated into a water reservoir and a water tube chamber having an extending portion for mounting a coffee pot thereon, an auxiliary housing integral with the main housing to mount a coffee bean container thereon, a coffee bean feeding means partially extending into the coffee bean container and being actuated by an electromagnetic element, a circular housing fastened onto the auxiliary housing and inserted within a brewing basket, a filter ring mounted within the brewing basket under the dripping ring, a stationary grinding element rigidly mounted within the brewing basket, a coffee bean grinding means being right under an socket and actuated by a motor, a water tube with a heating coil sleeved thereon in the water tube chamber, and a power supply.

Abstract: This invention concerns a car cleaner and air pump shaped like an elephant. It can be used as a vacuum cleaner, e.g. sucking in dirt, and at the same time as an air pump, e.g. pumping pressurized air into a tire. This elephant-shaped car cleaner and air pump consists of an elephant-shaped cover, a dirt sucking device, an air pumping device, a lighting signaling device and an electric power system. The characteristic of the dirt sucking device is that dirt is sucked through the trunk and collected in the dirt bag set in the body by means of a blowing wheel turned by a motor. The characteristic of the air pumping device lies in pumping air by means of a cylinder and a piston that is moved by a set of worm-gear wheel and rod turned by the same motor that is used in the dirt sucking device.

Abstract: A powdered milk dispensing device comprises a container for powdered milk having an outlet spout at the bottom through which the powder is fed by a screw conveyor. Bottles are held in place under the spout by a base assembly including an ultra-violet sterilizing lamp and push button switches for energizing the lamp and a small electric motor which drives the screw conveyor.
