Abstract

The utility model relates to an electric convection two-layer parasol, comprising a main parasol, an auxiliary parasol, a moving sleeve, a supporting frame for the main parasol, an auxiliary frame, a main parasol framework, an auxiliary parasol framework, a screw thread seat, a fan structure and an automatic switch, wherein, the center of circle of the parasol surface of the main parasol is provided with a circular hole; the miniature auxiliary parasol is arranged above the main parasol and the parasol frame of the miniature auxiliary parasol is fixedly arranged on the parasol frame of the main parasol by a fixed block, causing the two parasol surfaces to form space permeable to air. The parasol frames can achieve an opening and closing synchronous effect because the parasol frames are mutually fixed, and the top end point of a parasol stem is provided with a motor whose shaft center is connected with a moving blade. When the motor rotates, the moving blade is lifted as a result of the centrifugal action to achieve a convection effect when air goes in and out of the circular hole on the main parasol surface, and in the sun, opening the utility model can generate cooling feel under the parasol surface when encountering breeze and the utility model has the advantage of convenient operation.

Description

Electric convection two-layer parasol

The utility model relates to a kind of home-use parasols, refers to a kind of cross-ventilated double electrical layer parasols that carries out especially.

Arrive whenever the summer of sweltering heat, people go out or travel, and often carry a large-scale parasols, to avoid the sunlight direct irradiation.At present general large-scale parasols is made up of handle of umbrella, umbrella cover and support, by between support umbrella cover being strutted, and only hides sunlight by umbrella cover.Though traditional large-scale parasols can reach the purpose that hides the sunlight direct projection, yet if meet air quantity hour, the umbrella cover of this parasols can hinder gentle breeze on the contrary and enter, therefore, though can play the effect that sunshade keeps away day, under umbrella cover, really can produce a kind of sultry phenomenon virtually.

At the above-mentioned shortcoming of existing large-scale parasols, the purpose of this utility model provides and gets final product sunshade a kind of summer in sweltering heat, but can reach the convection current double electrical layer parasols of ventilating cool purpose again.

Detailed structure of the present utility model can describe in detail with the following Examples.

Fig. 1 is the utility model cross-sectional schematic.

Fig. 2 is fan user mode one schematic diagram of the present utility model.

Fig. 3 is fan user mode two schematic diagrames of the present utility model.

Fig. 4 is folding one schematic diagram of the present utility model.

Fig. 5 is folding two schematic diagrames of the present utility model.

The utility model is made up of main chute 3, secondary umbrella 4, umbrella handle 10, movable sleeve 11, eight main chute supports 31, eight auxiliary frames 311, eight main chute skeletons 30, eight secondary umbrella frame framves 40, threaded block 12, fan structure 20 and automatic shape C.

Wherein be arranged with movable sleeves 11 outside the

umbrella handle

10,11 of movable sleeves are equipped with eight main chute supports 31, these main chute support 31 other ends are to connect the inner appropriate location that is located at main chute skeleton 30, simultaneously, each main chute support 31 centre, then be equipped with auxiliary frame 311 in addition, its auxiliary frame 311 other ends are located on the fixedly pin joint seat 101 on umbrella handle 10 tops; At main chute skeleton 30 upper ends, then being installed with two fixed block 301(also can set up separately), 301 of this fixed blocks are fixed block 401 Joints that set firmly with secondary umbrella frame frame 40 tail ends, like this, main chute skeleton 30 and secondary umbrella frame frame 40 can obtain the synchronization action of suitable intensity, and secondary umbrella frame frame 40 upper ends wherein then are to be articulated on the umbrella top pin joint seat 50; Also be provided with a threaded block 12 at umbrella handle 10 top ends, it can connect for a fan 20 and establish, so that obtain having in the umbrella convection effects of fan, and this fan structure 20, actual is a battery tube 21, these battery tube 21 inner bottom are provided with screw thread 211 and can screw mutually with threaded block 12, simultaneously, in battery tube 21 upper ends is to be provided with a

motor

22,22 affixed blade seats 23 of motor, this blade seat 23 can connect establishes two sides (or three faces) blade 231, need to prove that this fan structure 20 needs two dry cell A are packed in the battery tube 21 in use, and battery tube 21 bottoms are screwed on the threaded block 12 on umbrella handle 10 tops, thereby can obtain direct current supply (because this conducting circuit is the very simple line construction that is similar to " flashlight ", so no longer set forth).In addition, these battery tube 21 sides are provided with a switch 210, use for opening or close fan; But convection current double electrical layer parasols of the present utility model produces cross-ventilated reason and is, be installed with one whole secondary umbrella umbrella cover 4 on the secondary umbrella frame frame 40, main chute skeleton 30 tops then set firmly a main chute umbrella cover 3, and offer one round at fixed block 301 places to discharge orifice B, to reach cross-ventilated effect.

Referring again to accompanying drawing 2, wherein, fan structure 20 in the running, the blade seat 23 that is driven because of motor 22 offers groove 230, and groove 230 is near the bottom, and it is corresponding with it then to be provided with boss piece 2301, and at the tail end of blade 231, then form a spherical end surface 2310, when snapping in groove 230, can obtain adeciduate effect, so when the motor transfixion by blade 231 caudal parts, then blade 231 is because of the cause of weight own, make this blade be a sagging state, and when motor starting rotates, then because of the rotary centrifugal force of blade seat 23, be one horizontal and blade 231 taken up, thereby reach cross-ventilated purpose, referring again to Fig. 3, Fig. 4, when the utility model need not and when desiring to fold, then motor 22 can cut out, motor 22 is stopped operating, and blade 231 loses centrifugal force, gets back to hang again, the movable sleeve 11 of umbrella handle 10 central authorities down can be folded then, so that collection is carried.10 of this umbrella handles can be in the bearing that movable sleeve 11 is unfurled an umbrella, add an automatic switch C, so that forget when closing switch 210 folding umbrella cover, in movable sleeve 11 processes of leaving behind, this automatic switch C can cut off the electricity supply automatically, and motor 22 is stopped operating, when avoiding folding, its blade 231 is with umbrella cover strand broken (this circuit is because of being general disconnect, so will not set forth).

Compared with prior art, the utility model can obtain the cross-ventilated cooling effect under the umbrella cover, and it uses simple, collects very convenient to carry.
