Description

Cooling blast waist band

Affiliated technical field

The present invention relates to the cooling blast waist band that staff under a kind of hot environment uses, especially can next to the skinly wear, the distinguished and admirable body surface that directly blows can be the blast waist band of back, chest, buttocks and hip borehole cooling.

Background technology

Under the overall background of climate warming, frequency and intensity that thermal extremes weather occurs become to tending to become strong more.According to statistics, during in June, 2010-July, total nearly 200 the weather monitoring station daily maximum temperatures in the areas such as China northeast, North China, Xinjiang, the Yangtze river basin and south China reach the extreme event standard, and wherein nearly 40 weather monitoring stations in Heilungkiang, Jilin, the Inner Mongol and Xinjiang are broken through historical extreme value.Large section zone surface temperature reaches 45-50 degree centigrade, some areas even reach 55 celsius temperatures, elevated temperature strength is big, more than the number of days, scope extensively be historical rare.

Although high temperature is hard to bear, numerous outdoor workmans under high temperature and heating summer still in tense working, such as sanitationman, traffic police, builder etc.Recognize during a sanitationman of Chinese Central Television's interview, this workman's whole body covers with prickly heat, and can't go to bed sleeping evening at all.

The patent that at present known and the present invention is close such as following:

A kind of portable mini-fan is disclosed in 92201211.3, its advantage is that blower fan separates with waistband, can be worn on the coat the inside to upper half of human body blowing cooling, but the waistband ventilating duct flattens easily, so that windage increases, do not realize the human body lower part of the body is lowered the temperature yet;

Disclose a kind of Waistband with ventilation device that can produce cool breeze in 99231137.3, its advantage is to form inner chamber in the middle of the waistband, and passage is arranged up and down, can ventilate up and down, but can not press close to skin when wearing;

Disclose a kind of chain type waistband that is comprised of hollow links in 200820105500.1, its advantage is that chain link is provided with air regulating board, can regulate the wind speed size, but can not press close to skin when wearing, and cost is higher;

Disclose a kind of air-cooled cooling belt that ventilation duct is set at belt in 200920242515.7, its advantage is venthole in the waistband side, and suffered resistance was less after air-flow flowed out from venthole, but can not press close to skin when wearing, and belt is thicker.

Outwork personnel shone for fear of ultraviolet ray, generally all is installed with thicker clothing and protects, and the wind that the cooling belt of wearing outside clothes produces seldom can pass clothing human body is lowered the temperature.In addition, during outwork, the most easily produce heat under human body back, chest, buttocks and the hip, and known patent documentation there is not realization to the cooling at these positions.

Summary of the invention

The invention reside in provides a kind of distinguished and admirable body surface that directly blows, and can next to the skinly wear, and can be the blast waist band of back, chest, buttocks and hip borehole cooling.

The present invention's technical scheme that adopts of dealing with problems is:

Described blast waist band, comprise pressure fan, wireway, with the waistband of built-in cavity and a plurality of ventholes, wherein, described pressure fan air outlet connects wireway, it is characterized in that: described built-in cavity is divided into two strip air-flow bands by a band, is pressed into the gas tight seal limit around the described waistband, and described blast waist band also comprises a triple valve, described triple valve one end connects wireway, and two ends are connected on the air admission hole of two different strip air-flow bands in addition.

A kind of optimal design of the present invention, described waistband venthole is that two rows are along the equally distributed triangle of air-flow band, described triangle venthole has a side parallel with the air-flow band, and described side is corresponding to a diagonal angle, and this diagonal angle is positioned at described side near a side of the center line of described waistband.

The present invention is preferred, and in the middle of the described waistband and two ends have outstanding, ledge a plurality of triangle ventholes that evenly distribute.

Particularly, described pressure fan comprises one by the rechargeable battery of switch connecting fan, a machine box that holds described pressure fan.

Particularly advantageously, described waistband is provided with a plurality of hidden discounts that waistband can be lain in waist.

The invention has the beneficial effects as follows:

1. this blast waist band width can be close to skin of lumbar region and wear greater than common waistband during use, then wears the clothes and fastens common waistband, and air-flow directly blows body surface from this blast waist band venthole, and cooling-down effect is obvious;

2. this blast waist band back side many triangle ventholes that evenly distribute, air-flow is discharged by each venthole, can be to carrying out fast cooling under back, chest, buttocks and the hip;

3. the triangle venthole is parallel with the air-flow band on one side outwardly, and the gas-flow radiation face is larger;

4. the triangle venthole is at the blast waist band back side, because the pressure-acting of sealing strip is so that wind direction is more pressed close to human body skin around the blast waist band, cooling rate is fast;

5. this blast waist band middle part and two ends have outstandingly, and outstanding position is under human body back, buttocks, hip and the easiest sweating of chest position, and that gives prominence to pore on the position can produce more air-flow, makes the position fast cooling of people Yi Fahan;

6. this blast waist band is formed by airtight or little ventilative soft material compacting, and air tight or little gas leakage is next to the skinly worn more comfortablely, and cost is lower;

7. this blast waist band is equipped with rechargeable battery, is convenient to the outwork librarian use;

8. there is belt fastener at the machine box back side, can directly heavier rechargeable battery, blower fan be lain on the common waistband, does not affect user's normal activity.
