Description

Cooling air blast waistband

Affiliated technical field

The present invention relates to the cooling air blast waistband that the staff uses under a kind of hot environment, especially can next to the shinly wear, the distinguished and admirable body surface that directly blows can be the air blast waistband of lowering the temperature under back, chest, buttocks and the hip.

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 areas such as China northeast, North China, Xinjiang, the Yangtze river basin and south China reach the extreme event standard, and wherein historical extreme value is broken through at nearly 40 weather monitoring stations in Heilungkiang, Jilin, the Inner Mongol and Xinjiang.Big portion zone surface temperature reaches 45-50 degree centigrade, the area that has even reach 55 celsius temperatures, elevated temperature strength is big, more than the number of days, scope extensively be historical rare.

Though high temperature is hard to bear, numerous outdoor workmans under high temperature and heating summer still in tense working, as sanitationman, traffic police, builder etc.The reporter of the Chinese Central Television (CCTV) recognizes when interviewing a sanitationman that this workman's whole body covers with prickly heat, and can't go to bed sleeping evening at all.

The patent that known and the present invention at present 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, make windage increase, also do not realize the human body lower part of the body is lowered the temperature;

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 of being made up 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 waistband that ventilation duct is set on belt in 200920242515.7, its advantage is venthole in the waistband side, and it is less that air-flow flows out the suffered resistance in back 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 waistband of wearing outside clothes is produced seldom can pass clothing human body is lowered the temperature.In addition, during outwork, be easy to generate heat most under human body back, chest, buttocks and the hip, and known patent documentation there be not the cooling of realization to 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 shinly wear, and can be the air blast waistband of cooling under back, chest, buttocks and the hip.

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

Described air blast waistband, comprise pressure fan, wireway, have the waistband of built-in cavity and a plurality of ventholes, a triple valve, wherein, described pressure fan air outlet connects wireway, and described triple valve one end connects wireway, and two ends are connected on the air admission hole of waistband in addition, 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.

A kind of optimal design of the present invention, described waistband venthole be two rows along the equally distributed triangle of air-flow band, described triangle venthole is parallel with the air-flow band on one side, the diagonal angle on described limit points to 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 a rechargeable battery by switch connection blower fan, a machine box that holds whole device.

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

2. this air blast waistband 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 bigger;

4. the triangle venthole is at the air blast waistband back side, because the pressure effect of sealing strip makes wind direction more press close to human body skin around the air blast waistband, cooling rate is fast;

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

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

7. this air blast waistband is equipped with rechargeable battery, is convenient to the outwork personnel and uses;

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 influence user's normal activity.
