Description

Technical Field

The present invention relates to the technical field of cooling technologies, and particularly to a cooling and ventilation device, a cooling hat, cooling shoes, and a cooling backpack.

Background

For example, ventilation, also called as change of air, is a process of feeding sufficient fresh air into an indoor space through a mechanical or natural method, and meanwhile discharging contaminated indoor air not meeting sanitary requirements, such that the indoor air is enabled to satisfy the requirements and demands in a manufacturing process. In architecture, various facilities for completing a ventilation process are collectively referred to as ventilation device. The ventilation devices include dedusting and purifying devices, cabinet type fans, fire control fans, centrifugal fans, water-curtain spray cabinets, air purifiers, dedusting fans, electrostatic oil fume purifiers, centrifugal smoke exhaust fans for fire control, cabinet-type centrifugal fans for fire control, luxury cabinet-type centrifugal fans, energy-efficient environment-protecting air conditioners, powerful exhaust fans, C6-48 centrifugal fans, 4-72 centrifugal fans, pulse dust collectors, cyclone dust collectors, purifying columns, and single-side single-station water-curtain cabinets.
However, the conventional ventilation devices still have a problem of relatively poor cooling effects.
For another example, hats serve functions of sun-shading, decoration, warming, protection and so on, as a result, there are a variety of hats, and the selection of a hat also should be given particular attention. Firstly, a suitable hat should be selected according to a facial form. Secondly, the hat should be selected according to stature of one's own. Like wearing clothes, wearing a hat should make best use of advantages and bypass disadvantages as much as possible. Style, color and so on of the hat must match the clothes and so on. However, the conventional hats still cannot address the problem of discomfort of a human body caused by sweating in daily travelling, that is, the conventional hats have relatively poor heat dissipation effects.
For another example, backpacks carried on back in marching or out-going are of a variety of materials, such as leather, plastic material, terylene, canvas, nylon, cotton and linen, and so on, which lead the fashion trend. Meanwhile, in the age of increasingly pursuing individuality, various types of styles such as simple style, retro style, cartoon style and so on also cater requirements of the fashionists for highlighting individuality from different aspects. Models of the bags are also developed from the conventional business bags, school bags, and travelling bags to pen bags, change purses, little sachets and so on. However, the conventional backpacks still cannot address the problem of discomfort caused by sweating on the back in travelling, that is, the conventional backpacks have relatively poor heat dissipation effects.
For another example, the birth of shoes is closely related to natural environment and intelligence of human beings. In ancient times, the ground was uneven, and the weather was harsh, then human beings instinctively demanded to protect their feet, thereby shoes came into being: hides and leaves simply tied up became the earliest shoes in the human history. However, with the progress of the human society and the improvement on people's living quality, discomfort caused by sweating in a walking process is inevitable, that is, the conventional shoes have relatively poor heat dissipation effects.
