Abstract: An energy-efficient hot water supply apparatus comprises a control assembly and a controller. The control assembly is disposed between an external energy supply source and a heating apparatus, so as to control turning on/off of energy supply of the energy supply source to the heating apparatus. At least one activation switch is disposed on the controller. The activation switch can operate the control assembly to cut off the entry of the energy of the energy supply source to the heating apparatus and keeps a fixed off duration.

Abstract: An umbrella structure capable of producing cool wind includes an umbrella shank. The umbrella shank is a hollow rod having a middle section formed with a plurality of air outlets thereon. A handle is provided with a power supply member (battery) therein. A circumferential portion of the handle at the junction of the handle and the umbrella shank is formed with a plurality of air inlets. A ventilating member is disposed in the handle. With a switch and a power supply member to conduct the ventilating member, the ventilating member is started to inhale air from the air inlets and produce an air current flowing into the umbrella shank and exhausting through the air outlets for providing cool wind to blow toward the user's face. The present invention provides a comfortable effect for the user.

Abstract: A car door rearview mirror structure having a mirror disposed on a rear side of the main body of the rearview mirror and electrically adjustable in inclination angle. A front cover body is mated with front side of the main body and a partitioning board is disposed in the main body to separate the front cover body from the mirror. A camera lens is disposed on the surface of front side of the partitioning board. The front face of the front cover body is formed with a window in front of the camera lens with a transparent cover fitted in the window to seal the window. By means of the camera lens and through the transparent cover, the view of a dead corner on a front side of the car is transmitted to a display arranged in the car so as to ensure driving safety.

Abstract: Quantitative cooking device including an electronic scale, a heater disposed on the electronic scale and a container to be heated by the heater. The heater is electrically connected with the electronic scale which controls powering on/off of the heater. The electronic scale compares the measured actual weight with the preset value. When the measured actual weight is equal to the preset value, the heater is powered off to stop heating the container. Therefore, the cooking will be stopped in accordance with the preset value and a quantitative cooking effect is achieved.

Abstract: A cap having a crown portion and a visor extended from a lower front of the crown portion is further provided at an upper part of the crown portion with a separated inner space for receiving a sunshade member therein and an openable top cover for closing the inner space. The crown portion is provided along a lower rear outer periphery with male fastener and the sunshade member is provided along an upper inner edge with female fastener. By opening the top cover, the sunshade member may be removed from the inner space in the crown portion and detachably attached to rear side of the crown portion by engaging the female fastener with the male fastener. The sunshade member connected to rear side of the crown portion of the cap may shield a large area of a wearer's nape and cheeks from sunrays.

Abstract: A water temperature regulator having a closed container that is provided with a cold-water inlet pipe and a hot-water inlet pipe having flow control connected thereto for introducing cold and hot water, respectively, into the container at a desired flow rate, a discharge pipe for guiding water in the container to an external water storage, at least one water service pipe for guiding water in the container to at least one water supply outlet, such as a showerhead or a faucet, at least one control for controlling open/close of the discharge pipe and of the at least one water service pipe, and a water temperature indicator for showing a temperature of water in the container. Instead of being drained, water introduced into the container that has not reached a desired temperature is discharged to and stored in the water storage for reuse later without being unnecessarily wasted.

Abstract: A practice golf ball is produced by sewing up at least two pieces of preferably symmetrical surface cloth to form a ball shell defining a spherical space therein and evenly stuffing fibrous material into the spherical inner space via an opening left on a seam between the sewed-up surface cloths. The opening is then sewed up to seal the fibrous material in the ball shell. A thermosetting resin is injected into a geometrical center of the ball shell. When the resin is cooled and set, it binds the fibrous material at the geometrical center and forms a weighted core that provides a stable center of gravity for the completed practice golf ball.
