The invention discloses a piece of fragrance underwear, which comprises a breast supporter, an inner liner, a lacing belt, shoulder straps and fragrance bags in independent arrangement, wherein the inner liner is arranged at the inner surface of the breast supporter; an interlayer space is formed between the inner liner and the breast supporter; the fragrance bags are arranged in the interlayer space; the lacing belt is connected with the two sides of the breast supporter; one end of each shoulder strap is connected with the upper end of the breast supporter; the other end of each shoulder strap is connected with the upper end of the lacing belt. By using the mode, the fragrance underwear has the advantages that the structure is novel; the breasts are protected; the independent fragrance bags are arranged in the fragrance underwear; the fragrance is pleasant; the body and the mind are relieved; safety, protection, convenience and practicability are realized, and the like. Wide market prospects are realized in fragrance underwear popularization.

The invention discloses a safely foldable automatically expanding / collecting umbrella, which comprises a telescopic umbrella middle rod, an expandable umbrella rib device and a ratchet and pawl device, wherein the ratchet and pawl device is arranged in the umbrella head. The spindle of a ratchet is provided with a rope; the ratchet is connected with a clockwork spring; the clockwork spring is tightened when the ratchet rotates counterclockwise, and the ratchet rotates clockwise when the clockwork spring is loosened; and a ratchet spring which is used for driving a pawl to match with the ratchet is arranged in the umbrella head. When the middle rod is pressed in an umbrella closing process, under the braking action of the pawl, the ratchet only can rotate clockwise; and under the action ofthe clockwork spring, the ratchet rotates clockwise to collect the rope, wherein if the middle rod is incautiously released in the clockwise rotation of the ratchet, the rope is tightened but the ratchet cannot rotate counterclockwise, so the rope can fix the middle rod to prevent the middle rod from being sprung off. Therefore, the safely foldable automatic expanding / collecting umbrella has the effect of safety protection.

The invention discloses a wind and sand prevention method adopting an electromagnetic-type reinforced on-wall fence with a gauze mesh, and relates to a wind and sand prevention method adopting a fencewhich is perspective and simultaneously has the functions of safe protection and wind and sand-dust prevention. The defects that in the prior art, as for a full-closed fence, full-circulating of aircannot be achieved, and as for a perspective fence, the magnitude of wind power passing through the fence cannot be effectively controlled, and wind and sand-dust cannot be prevented are overcome. Themagnitude of force of wind blowing up a hanging curtain is adjusted through attraction force of a magnetic field between a reset magnet at the bottom of the hanging curtain and a fixed magnet on thefence, the motion range of the hanging curtain is adjusted through a clamping rod capable of moving up and down, the magnitude of the force of the wind passing through the fence is further controlledeffectively, and thus the purposes that the fence is perspective, the space above a reinforcing transom and the space below the reinforcing transom can be controlled independently, the magnitude of the force of the wind in spaces with the different heights can be controlled, meanwhile, safe protection is achieved, and wind and sand-dust prevention are effectively controlled are achieved, and the technical effect in the aspect of adjusting of the ventilation amount of the fence is particularly prominent.
