Ultraviolet ray and infrared ray preventing biconvex umbrella

Abstract

The invention relates to an ultraviolet ray and infrared ray preventing biconvex umbrella comprising an umbrella rib, an umbrella stick, an umbrella rib holder, an umbrella cap and an upper umbrella cover, wherein the center of the upper umbrella cover is fixed on the top end of the umbrella stick through the umbrella cap; and a lower umbrella cover is arranged below the upper umbrella cover in a mirror-image way to form a biconvex structure with an eye-shaped outline. Due to the biconvex structure, the ultraviolet ray and infrared ray preventing biconvex umbrella can insulate direct infrared rays and ultraviolet rays on a heat insulation layer formed between the upper umbrella cover and the lower umbrella cover, diffuse reflected infrared rays and ultraviolet rays out of the umbrella through the lower umbrella cover so that various rays below the umbrella covers are not collected and gathered any more and a formed shadow is even cooler, thereby achieving the purpose of preventing the infrared rays and the ultraviolet rays and effectively enhancing the health degree of a user; in addition, the umbrella rib is wrapped by the lower umbrella cover without causing mechanical injury on the user in the using process.

Description

technical field [0001] The invention relates to an umbrella in daily necessities, in particular to a double-convex umbrella with anti-ultraviolet and infrared rays that can protect the sun and rain, has no mechanical damage to the human body, and improves the health of users. Background technique [0002] With the intensification of environmental pollution and the accelerated emission of carbon dioxide, the earth has formed a serious greenhouse effect, and the annual average temperature of the earth has increased year by year. In summer, various large cities have been reduced to "stoves" and have sustained high temperatures, causing infrared and ultraviolet rays to go crazy. ravaged the ground and caused serious damage to the human body. [0003] Infrared rays, also known as heat rays, are an invisible ray with thermal effect properties. All substances above absolute zero (-273°C) can produce infrared rays. Trees and grass can reflect a large amount of infrared rays due to ...

AI Technical Summary

Problems solved by technology

[0007] 1. When there is wind, the concave shape is easy to go for a ride, and the concave umbrella surface is easy to be blown over by the wind;

[0008] 2. When the distance between the umbrella surface and the user's head is relatively close, the hair is easily caught by the umbrella ribs, so the umbrella is lifted high to keep the umbrella surface away from the head; The area is relatively small, which is not conducive to shade and rain, and it is laborious to carry an umbrella;

[0009] 3. When the umbrella is opened and closed, the human hand is easy to come into contact with the umbrella bone and the iron wire of the umbrella bone connection plate, causing stab wounds, hanging injuries, and pinch injuries;

[0010] 4. When walking with an umbrella, the concave umbrella surface is likely to affect the sight of the user of the umbrella, and there is a hidden danger to others and to yourself;

[0011] 5. When shading, there is no heat insulation layer in a certain space, and the hot air in the concave surface is blocked, and the heat of the umbrella cloth directly radiates to the umbrella, which cannot effectively form a shade unde
