Summary of the invention
The utility model mainly is to solve existing in prior technology can not reasonably lead from the wind that the downside of umbrella cover is blown into, make easily under the situation of blowing, people need could hold umbrella with very big power, occurring umbrella cover is sometimes pressed and is turned over, even occur technical problem such as blowing away because of holding, a kind of simple in structure, good looking appearance is provided, and the wind that the downside from umbrella cover is blown into has the decompression umbrella of good guide effect.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of decompression umbrella, comprise umbrella handle, umbrella stand, umbrella cover, it is characterized in that described umbrella cover circumferentially is evenly distributed with several ventilating openings, the outer side covers of described ventilating opening has blinker, the edge of blinker is divided into fixed edge and free margins, the upper edge of described fixed edge and ventilating opening fixes, described free margins exceeds ventilating opening edge 0.5-3cm, described ventilating opening is arc, wherein this arc arc limit up, the fixed edge of described blinker and this arc limit are fixed, and the length of the free margins of described blinker is than the big 1-4cm of pairing umbrella cover length between its two ends fixing point.When wind when the downside of umbrella cover is blown into, because the length of the free margins of blinker is than the big 1-4cm of pairing umbrella cover length between its two ends fixing point, blinker promptly forms domes, make gas flow out from the air port of these domes, effectively solved because the very difficult pulling that wind occurs when the umbrella cover bottom is blown into, the problem of turning on the umbrella cover has made things convenient for people's use.Simultaneously, because the ventilating opening has here adopted bow-shaped structural, the arc limit of its upside is also more reasonable to the guiding of air-flow, has effectively reduced its resistance to air-flow.Free margins exceeds the ventilating opening edge can prevent that rainwater from falling in the rain from umbrella cover top, and the wind that also can prevent to blow from umbrella cover top south blows to the free margins of blinker in the ventilating opening, and air-flow is imported in the umbrella.
As preferably, described umbrella cover is made of 8 umbrella lobes, is respectively equipped with a ventilating opening on each umbrella lobe, and the area of each ventilating opening is 30-60cm
2If the area of ventilating opening is too little, wind-guiding is limited in one's ability, can not reach the effect of decompression, if energy air port area is excessive, is difficult to guarantee that the free end of blinker can not extend in the ventilating opening, has influenced the ability of keeping out wind and rain of umbrella.The distribution of ventilating opening must be even, makes umbrella stressed even when wind-engaging, is difficult for destroyed.
As preferably, the distance on described ventilating opening and umbrella top is the 1/4-1/2 of umbrella lobe length.Because general umbrella lobe all is an arcwall face, below is big more with the angle of horizontal plane more for it, therefore, if ventilating opening below too, will inevitably have influence on the ability of its water conservancy diversion, if establish too high, may make that then the wind of umbrella cover upside is blown into, even have rainwater to enter easily.
The beneficial effect that brings of the present utility model is, having solved existing in prior technology can not reasonably not lead from the wind that the downside of umbrella cover is blown into, make easily under the situation of blowing, people need could hold umbrella with very big power, occurring umbrella cover is sometimes pressed and is turned over, even occur technical problem such as blowing away because of holding, realized a kind of simple in structure, good looking appearance, the wind that the downside from umbrella cover is blown into has the decompression umbrella of good guide effect.
