Embodiment 1

[0045] refer to figure 1 and figure 2 , an umbrella, including an umbrella body 1, the umbrella body 1 is a common umbrella structure in life, wherein the top of the middle stick 10 in the umbrella body 1 protrudes from the umbrella surface 11, in order to make the umbrella have the effect of an air umbrella, the middle stick The top end of 10 is connected to the lower casing 13 through the connecting part 2, and the lower casing 13 is connected to the upper casing 12 through the connecting rod 120, and an annular air outlet 14 is left between the lower casing 13 and the upper casing 12. An aerodynamic part 3 is also arranged between the upper casing 12 and the lower casing 13, and a dense air inlet 131 is provided at the bottom of the lower casing 13, and the aerodynamic part 3 passes the airflow outside the lower casing 13 through the air inlet 131. After being sucked into the upper shell 12 and the lower shell 13, it bulges out from the air outlet 14; when using an umbrel...

Embodiment 2

[0055] The difference from Embodiment 1 is that the upper surface of the upper casing 12 is coated with a layer of antifouling coating, because when the umbrella is in use, the upper surface of the upper casing 12 is used as the top surface to easily accumulate dust. The adhesion on the upper surface of the upper shell 12 is difficult to clean, so a method for preparing an antifouling coating is provided, which has the advantages of short preparation process and simple preparation, wherein the antifouling coating on the upper surface of the upper shell 12 The preparation method is as follows:

[0056] Take the following components by weight for subsequent use: 32 parts of polyvinyl chloride, 38 parts of polypropylene, 43 parts of polycarbonate, 21 parts of polyacrylic resin, 13 parts of ethyl acetate, 14 parts of glycerol, and 11 parts of sodium acrylate 8 parts, 8 parts of polyacrylamide, 8 parts of sodium benzoate;

[0057] S1. Perform surface treatment on the upper surface...

Embodiment 3

[0063] The difference from Example 2 lies in the preparation of the antifouling coating on the upper surface of the upper casing 12, wherein the preparation method of the antifouling coating on the upper surface of the upper casing 12 is as follows:

[0064] Get the following components by weight for subsequent use: 33 parts of polyvinyl chloride, 39 parts of polypropylene, 44 parts of polycarbonate, 22 parts of polyacrylic resin, 13 parts of ethyl acetate, 14 parts of glycerol, and 11 parts of sodium acrylate 8 parts, 8 parts of polyacrylamide, 8 parts of sodium benzoate;

[0065] S1. Perform surface treatment on the upper surface of the upper casing 12: use sandpaper to polish the upper surface of the upper casing 12, and polish the groove surface to R9 level of roughness;

[0066]S1. Preparation of anti-fouling coating pre-preparation solution: mix polyvinyl chloride, polypropylene, polycarbonate, polyacrylic resin and ethyl acetate evenly and add to the reaction kettle, th...

Abstract

The invention discloses an umbrella, and belongs to the field of waterproof devices. According to the technical scheme, the umbrella is characterized by comprising an umbrella body, the top end of a middle bar in the umbrella body protrudes out of an umbrella fabric, the top end of the middle bar is connected with a lower shell through a connecting part, the lower shell is connected with an uppershell through a connecting rod, an annular air outlet is reserved between the lower shell and the upper shell, an air power part is arranged between the upper shell and the lower shell, dense air inlets are formed in the bottom of the lower shell, and the air flow outside the lower shell is sucked into the space between the upper shell and the lower shell by the air power part through the air inlets and is then blown out of the air outlet. The improved umbrella has quite high attractiveness, can show personality, can select to work like a traditional umbrella and can select to shield rain as an air umbrella without unfolding the umbrella fabric, the umbrella fabric does not need to be unfolded when the umbrella is used as the air umbrella, and the occupied land is quite small.

Description

technical field [0001] The present invention relates to the field of waterproof devices, more specifically, it relates to an umbrella. Background technique [0002] An umbrella is a tool for shading or sheltering from rain and snow. Modern common umbrellas are generally made of oiled paper, oiled cloth or plastic cloth. Since the existing umbrella has a single structure and shape, it is not eye-catching enough to show individuality well when used, so it can be improved; in addition, the existing umbrella has a large umbrella surface when used, and the experience when opening the umbrella is not good. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an umbrella to solve the problems mentioned in the background art. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] An umbrella, comprising an umbrella body, the top end of the midd...
