DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] like Figure 1-Figure 3 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the dust on the surface of the curtain fabric will be swung out when it swings with the wind and scatter into the room to cause pollution, a flip mechanism is disclosed:

[0030] The surface layer 1 comprises a middle layer 2 connected to the bottom of the surface layer 1, a bottom layer 3 connected to the bottom of the middle layer 2, a polyester fiber 101 is internally provided in the surface layer 1, a nylon fiber 102 is mixed and woven inside the polyester fiber 101, a polypropylene fiber 103 is connected to the top of the nylon fiber 102, an electrostatically spun fabric 104 is connected to the top of the polypropylene fiber 103, a polyurethane coating 105 is applied to the surface of the electrostatically spun fabric 104, an adsorption mechanism for reducing dust dispersion is provided in the surface layer 1, a polyethylene bubble 201 is internally provided in the middle layer 2, the polyethylene bubble 201 is connected in a bilaterally symmetrical manner, and a heat insulation mechanism for reducing heat transfer is provided in the middle layer 2;

[0031] When the curtain cloth is in use, dust will fall on the surface of the polyurethane coating 105. The polyurethane coating 105 can form a protective layer to prevent the adhesion and accumulation of dust. When the polyurethane coating 105 is worn out during use, the dust can fall on the surface of the electrospun fabric 104. The electrospun fabric 104 has an electrostatic adsorption effect and can adsorb dust. At the same time, the polypropylene fiber 103 also has a good electrostatic adsorption effect, which can further increase the adsorption performance of the surface layer 1 to prevent dust from shaking in the wind and drifting into the room, causing indoor dust pollution and accumulation. When the dust accumulates to a certain extent, it can be manually cleaned and wiped, which is more convenient to use. Finally, by mixing the polyester fiber 101 and the nylon fiber 102, the wear resistance of the curtain cloth can be increased without reducing the electrostatic adsorption performance, preventing the dust from drifting while improving the durability of the curtain cloth.

[0032] Embodiment 2:

[0033] like Figure 1 , Figure 2 and Figure 4 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the curtain fabric has high heat transfer efficiency, resulting in high indoor temperature, affecting the indoor environment quality and thus affecting the comfort, a flip mechanism is disclosed:

[0034] The heat-insulating mechanism includes a cotton filler 202, and the cotton filler 202 is filled between two polyethylene bubbles 201. The cotton filler 202 and the top of the polyethylene bubble 201 are connected with a heat-insulating gauze 203. The top of the heat-insulating gauze 203 is coated with an aluminum foil coating 204. The bottom layer 3 is provided with a sound-insulating mechanism to reduce the transfer. When the curtain cloth is in use, light heat will be transferred to the surface of the electrostatic spinning cloth 104. The electrostatic spinning cloth 104 can reflect the light heat, thereby preventing heat from entering the room from the window. Part of the heat will continue to be transferred to the inside of the polypropylene fiber 103. The polypropylene fiber 103 can effectively reduce the conduction and transmission of heat through its own material, thereby further improving the heat-insulating effect of the curtain cloth. In order to achieve the best heat-insulating effect, polyethylene bubbles 201 are added to the middle layer 2. The polyethylene bubbles 201 can form a bubble isolation layer on both sides of the curtain cloth while maintaining the balance of the curtain cloth. The nylon fiber 102 can reduce part of the heat transferred by the polypropylene fiber 103, provide additional heat-insulating protection, and make the curtain cloth have better heat-insulating performance.

[0035] Embodiment three:

[0036] like Figure 1 , Figure 2 and Figure 5 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the curtain cloth has poor sound insulation effect, reduces the comfort of the indoor environment, and causes the user's sleep quality to decline, a flip mechanism is disclosed:

[0037] The sound insulation mechanism includes sound-absorbing cotton 301, which is connected to the inside of the bottom layer 3, and the bottom of the sound-absorbing cotton 301 is connected to rubber foam 302, and the bottom of the rubber foam 302 is connected to six groups of weighted lead balls 303. The sides of the surface layer 1, the middle layer 2 and the bottom layer 3 are all connected to frames 304. When the curtain cloth is used, the sound emitted from the outside will be transmitted to the inside of the rubber foam 302. The rubber foam 302 can reduce the propagation of sound through density and elasticity. The reduced sound will continue to be transmitted to the inside of the sound-absorbing cotton 301. The sound-absorbing cotton 301 can absorb the sound through its own material, thereby reducing the reflection of the sound. The radiation and transmission of the curtain cloth further improve the sound insulation effect of the curtain cloth. Finally, in order to prevent the sound from being transmitted through the gap between the curtain cloth and the window frame, a frame 304 can be added to the side of the curtain cloth. The frame 304 can improve the sealing effect between the curtain cloth and the window frame, thereby reducing the penetration of air and sound. In order to keep the curtain in a vertical state, a weighted lead ball 303 can be added to the bottom. The weighted lead ball 303 can straighten the curtain cloth by its own gravity, thereby maintaining the stability of the curtain cloth, effectively exerting the performance of the sound insulation material, improving the sound insulation effect, creating a quiet environment, and making it more comfortable to use.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
