CN2260471Y - Cooling cap with fan - Google Patents

Abstract

The utility model relates to a cooling cap with a fan, which can drive the fan to blow continuously for a long time in the sun. The utility model is composed of a solar panel (1), a DC electric motor, a small fan (2), conducting wires (3) and a cooling cap (4). The solar panel (1) installed on the top of the cap generates direct current through photoelectric conversion in the sun to drive the DC electric motor and the small fan (2) to rotate to generate wind, causing a cap user to feel cool under the blazing sun. The utility model needs no dry battery consumption, and the utility model has convenient use.

Description

The summer hat of band fan

The utility model relates to a kind of summer hat with fan, belongs to daily tourism supplies technical field.

Existing summer hat generally has only the function of sunshade, and the person of attaching the names of pre-determined candidates still has sultry sensation under The sun is shining fiercely, especially under calm situation.A kind of summer hat with fan is also arranged in the market, but it is to adopt dry cell power supply,, needs often to replenish, use inconvenient, also uneconomical because battery consumption is fast.

The purpose of this utility model overcomes the deficiencies in the prior art exactly, and a kind of dry cell that do not need is provided, and is easy to use, can successively blow the summer hat of breezy cool breeze in the sun from the trend person of attaching the names of pre-determined candidates.

In order to achieve the above object, the summer hat of the utility model band fan is equipped with solar panel on crown, the solar panel of 100 * a 65 * 7mm (about 70 grams of weight), can produce the DC current of 3.5V, 70mA in the sun continuously, power to a miniature cocurrent electromotor by lead, its driving power is 0.25-0.3W.The axle of this dc motor is gone up one 4 leaf small fan (about 100 grams of weight) is installed.Direct current generator and fan are screwed and are having on the bongrace of slotted eye, and fan outlet faces the person's of attaching the names of pre-determined candidates forehead and face.In the middle of the lead that connects solar panel and dc motor, a connector is arranged, can make switch and use.Under solar light irradiation, solar panel absorbs luminous energy, produces DC current after opto-electronic conversion, powers continuously to fan electromotor, and fan is rotated at a high speed, produces enough air quantity, brings a slice slight chill in the air for the person of attaching the names of pre-determined candidates.When natural wind is arranged, can take out the connector on the lead, the fan stall is used as common summer hat.

The summer hat of the utility model band fan is owing to adopt solar powered, need not consume dry cell, but long-time continuous drives fan air-supply in the sun, easy to use, economical and practical, be very suitable for the labourer that works in the sun season hot summer, the traveller, the football fan and the student that see ball in the court use.

Fig. 1 is the schematic appearance of the summer hat of the utility model band fan.

Fig. 2 is solar cell panel structure figure of the present utility model shown in Figure 1.

Fig. 3 is dc motor of the present utility model shown in Figure 1 and small fan structure chart.

Fig. 4 is circuit theory diagrams of the present utility model shown in Figure 1.

Be described in further detail below in conjunction with the drawings and specific embodiments the utility model.

As shown in Figure 1, the utility model is made up of solar panel 1, dc motor and small fan 2, lead 3 and summer hat 4.Solar panel 1 produces direct current through opto-electronic conversion in the sun, makes the rotation generation cool breeze at a high speed of dc motor and small fan 2 by lead 3, and 4 of summer hats play the effect of sunshade and fixing above-mentioned each parts.The structure of solar panel 1 as shown in Figure 2, it by plastic frame 5, with glass be substrate non-crystal silicon solar cell 6, plastic bottom board 7, form with the lead 10 of the fixing screw 8 of summer hat 4 and packing ring 9, band plug, it is of a size of 100 * 65 * 7mm, weighs 70 grams.This solar panel open-circuit voltage 3.7-4.0V in the sun, supply current can reach 70-100mA, power output 0.25-0.35W.Solar panel can not damage when being in open circuit.The structure of dc motor and small fan 2 as shown in Figure 3, it is made up of plastic housing 13, fixing screw 14 and the packing ring 15 of 4 leaf plastics small fans 11, permanent magnet direct current motor 12, band fixed mount, the lead 16 of band socket, heavily about 80 restrain.

Circuits System schematic diagram of the present utility model as shown in Figure 4.It is made up of solar panel 1, dc motor and small fan 2, lead 10,16 and plug 17, socket 18.Wherein, plug 17 and socket 18 replace power switch.This circuit solar panel non-loaded (open circuit) voltage in the sun can reach the 4-6 volt, and the voltage under motor load is the 3-3.5 volt, operating current 70-80mA, power output 0.25-0.3W.The utility model solar panel life-span is greater than 5000 hours, about device gross weight 150 grams.Solar energy small fan device of the present utility model can be installed in Travelling hat of all kinds, Sunshade cool cap, field work cap, safety cap of shade etc.; Solar panel can be made up of 1 or several piece.

Claims (2)

1, a kind of summer hat with fan, comprise summer hat (4) and be fixed on dc motor and small fan (2) on the bongrace, it is characterized in that: the solar panel (1) of non-crystal silicon solar cell (6) formation that is substrate is installed on crown with glass, and it is connected to dc motor and small fan (2) by lead (3).

2, the summer hat of band fan according to claim 1 is characterized in that: the summer hat that solar panel (1) and dc motor and small fan (2) are installed is traveling-cap, sunbonnet, working cap or safety cap; The solar panel of being installed (1) is by forming more than 1 or 1.
