The invention discloses an extremely simple windproof coat hanger which comprises a coat hanger body and a hook, wherein a certain part of the hook is provided with a rubber area and other parts of the hook are made of plastics or other hard materials, or the whole of the hook is made of rubber; and the tail end of the hook deflects outwards. As the rubber increases the elasticity of the hook, the hook can be easily hung on an airing rod under the guide action of the outward-deflecting structure at the tail end of the hook when the opening of the hook is obviously smaller than the diameter of the airing rod. As the opening of the hook is smaller than the diameter of the airing rod, the coat hanger can not be easily blown off by wind and can be easily taken down when the coat is to be taken back, thereby obviously facilitating the use process. The windproof coat hanger provided by the invention has no additional new structural part based on the traditional coat hanger, and has an extremely ...

Electric foot wiping machine

The invention discloses an electric foot wiping machine, which consists of a motor, transmission mechanisms, two mutually parallel longitudinal shafts, two mutually parallel transverse shafts, a drying device, a disinfecting device, a case and a ventilation system, wherein soft strip-shaped water absorption materials are arranged on the surfaces of the transverse shafts and the longitudinal shafts, the inner surfaces of the bottoms of the transverse shafts and the longitudinal shafts are provided with water absorption materials, the rotating movement of the motor is converted into the rotating movement of the two longitudinal shafts and the two transverse shafts through four groups of transmission mechanisms, and the soft strip-shaped water absorption materials are driven to rotate. The electric foot wiping machine has the beneficial effects that the fast rotating soft strip-shaped water absorption materials can fast wipe and dry the residual moisture at the feet after a user wash the feet ...

Electric foot wiping machine

The utility model discloses an electric foot wiping machine. The electric foot wiping machine consists of a motor, transmission mechanisms, two vertical shafts in parallel, two horizontal shafts in parallel, a drying device, a disinfecting device, a casing and a ventilation system, wherein soft bar-shaped water-absorbing materials are arranged on the surfaces of the horizontal shafts and the vertical shafts, and water-absorbing materials are arranged on the inner surfaces of the bottoms; rotation movement of the motor is converted into the rotation movement of the two vertical shafts and the two horizontal shafts through four sets of the transmission mechanisms, and the soft bar-shaped water-absorbing materials are driven to rotate. The electric foot wiping machine disclosed by the utility model has the benefits that the soft bar-shaped water-absorbing materials in quick rotation can quickly wipe and dry residual water on feet of a user after foot washing, and through the disinfecting device ...

Oil filtering spoon

The invention discloses an oil filtering spoon. The oil filtering spoon is composed of a spoon handle and a spoon body. A soup inlet hole is formed in the bottom of the spoon body or nearby the bottom of the spoon body, the soup inlet hole is a stepped hole, and a step is arranged on the upper portion of the soup inlet hole. A hole cover is arranged on the upper portion of the soup inlet hole, the hole cover and the spoon body form a whole through a soft connecting device, and the hole cover can rotate around the soft connecting device. When the hole cover is rotated to the lowest position, the hole cover exactly falls to the step on the upper portion of the soup inlet hole, and accordingly the soup inlet hole is sealed. The oil filtering spoon has the advantages that soup without grease basically can be obtained smoothly from a stockpot or a soup bowl, and soup taking is completed; when the soup spoon is moved out of the pot or the bowl, under the effect of the gravity of the soup in the ...

Transparent heat-insulated paint based on nano spectral selectivity compound oxide

The invention relates to transparent heat-insulated paint based on nano spectral selectivity compound oxide, which can be coated on the surfaces of glass, transparent resin, a transparent film, metal and cement. The paint comprises nano spectral selectivity compound oxide pulp, polyurethane resin, acrylic resin, alkyd resin, isocyanate resin, amino resin, a paint auxiliary agent, a diluting agent and the like.
