Suspension umbrella

Abstract

The invention discloses a suspension umbrella with hollow closed propeller blades, low-noise air injection and an automatic mode selection function and a use method of the suspension umbrella. An aircraft, a sensor, a magnet and an inflating and deflating device are embedded into hollow umbrella covers which are made of various materials and have various specifications and various shapes; the fabric of the umbrella cover and the umbrella bottom is made of various materials such as polyester fibers, terylene, chinlon and the like; a waterproof, sun-proof, ultraviolet-proof, fireproof and airtight coating and a coating for collecting solar energy are coated in the umbrella lining of the hollow umbrella cover, or a solar film and other components are arranged in the umbrella lining of the hollow umbrella cover; the periphery of the upper half portion of each independent propeller blade is provided with a hollowed-out protective cover with a waterproof strip, the periphery of the lower half portion of each independent propeller blade is provided with a spiral pipeline sealed with noise reduction materials, and turbine blades are installed between the propeller blades and the motor; through sensing of the sensor, the suspension umbrella can automatically select modes; and the suspension umbrella can follow the human body to track and move without support, avoid obstacles and suspend.

Description

Technical field: [0001] The invention belongs to the technical field of aircraft, and in particular relates to a suspension parachute. Background technique: [0002] Umbrella is a kind of tool for sunshading or covering rain and snow, which provides many conveniences for people's life, but there are many shortcomings in the umbrellas on the market at present.

AI Technical Summary

Problems solved by technology

For example, in summer, students are active and exercising in the playground without a cover, and sanitation workers, policemen, and administrative law enforcement personnel work in the rain and under the scorching sun. The umbrellas used need to be supported by hands or by the head and back; there are no single or multiple umbrellas on the market. The choice of use mode; the propeller blades of the aircraft configured on the parachute are open, semi-open or have a specious protective cover, and the noise is very loud. The high-speed rotating propeller blades are easy to hurt people or things, which brings great safety. Hidden danger is another serious nuisance problem; aircraft are powered by their own batteries to move, with limited battery life and limited mobile load, etc.
