Embodiment 1

[0020]The damping and shock-absorbing matrix described in this embodiment is made of a composite material of resin and inorganic material; it contains 18.0wt% of MDI, 3.0wt% of hydroxyl-terminated polybutadiene (Polybd brand R-15HT of CrayValley Company), 1.2wt% of trimethylolpropane, 2.2wt% of benzoic acid-2-hydroxyethyl ester, 5.0wt% of vinyltrimethoxysilane, 32.0wt% of diglycidyl acrylate, and the balance of three Aluminum oxide (average particle size 20μm). The preparation method of the damping and shock-absorbing matrix is ​​as follows: Weigh the components according to the proportion, mix and disperse the components except MDI, then add the MDI, stir and mix evenly, cast and solidify, and then pour and solidify at 120 ℃, curing 50min.

Embodiment 2

[0022] The damping and shock-absorbing matrix is ​​made of a composite material of resin and inorganic material; it contains 20.0wt% of MDI, 2.5wt% of hydroxyl-terminated polybutadiene (Polybd grade R-15HT of CrayValley Company), 1.5wt% Trimethylolpropane, 2.0wt% benzoic acid-2-hydroxyethyl ester, 4.0wt% vinyltrimethoxysilane, 28.0wt% diglycidyl acrylate and the balance of aluminum oxide ( Average particle size 20μm). The preparation method of the damping and shock-absorbing matrix is ​​as follows: Weigh the components according to the proportion, mix and disperse the components except MDI, then add the MDI, stir and mix evenly, cast and solidify, and then pour and solidify at 120 ℃, curing 50min.

Embodiment 3

[0036] The water-resistant protective layer is formed on the base of the fan blade with a thickness of 200 μm. It is made of 20.5wt% MDI, 13.5wt% hydroxyl-terminated styrene-butadiene liquid rubber (produced by Shandong Zibo Qilong Chemical Co., Ltd., type II), 4.2 wt% of PTMG1000, 1.8wt% of 1,4-butanediol, 1.2wt% of ethoxylated bisphenol F diacrylate, 1.5wt% of vinyltriethoxysilane, 0.15wt% of defoamer BYK -028, 0.15wt% leveling agent BYK-346, 0.20wt% dibutyltin dilaurate, 8.5wt% titanium dioxide (average particle size 10μm), 9.0wt% dimethyl carbonate and the rest Stir ethyl acetate at a stirring speed of 300-400 rpm for 30 minutes to obtain a polyurethane prepolymer, and then prepare and dry the polyurethane prepolymer by casting or coating to obtain the water-resistant protective layer.

Abstract

The invention relates to a centrifugal spraying fan comprising an ultralow safe voltage motor. The centrifugal spraying fan comprising the ultralow safe voltage motor comprises a box body for containing liquid, a spraying unit and a fan unit; the box body provides the spraying unit with liquid through a pipeline when required, the spraying unit centrifuges the liquid provided by the box body and enables the liquid to form sprays through impact; the fan unit comprises a plurality of fan blades which are used for producing air flow; the spraying unit is arranged at the air outlet of the fan blades so as to lead the sprays produced by the spraying unit to the air flow, and accordingly the adjustment of the temperature and the humidity of ambient air can be achieved. The centrifugal spraying fan comprising the ultralow safe voltage motor can achieve power supply through application of ultralow safe voltages, eliminates dangers of damage to people, which are caused by electric leakage, and can be adapted to a variety of power supplies; can be used in various occasions such as homes, the outdoors and public space to adjust air temperature and humidity; has the advantages of being convenient to move, energy-saving, environmentally friendly and safe in usage.

Description

technical field [0001] The invention relates to the technical field of household appliances, more specifically the invention relates to an electric fan with a spraying function. Background technique [0002] Electric fans are widely used as the main ventilation and heat dissipation appliances in summer, but most of the electric fans are only for ventilation and heat dissipation. In order to be suitable for dry and hot areas, electric fans need to provide certain humidity while ventilating and heat dissipation. The misting fan that appeared on the market in recent years is a new type of fan that combines a liquid storage container and a spraying device on the basis of a traditional fan. Operate the spray device to draw water from the reservoir and spray it out as a mist. Using a spray fan in summer, in addition to the cool wind blown by the fan itself, makes full use of the principle of water vaporization and sprays the human body with tiny water droplets to achieve a better...
