Description

Technical Field

[0001] This utility model relates to the field of PE film, and in particular to a highly breathable and waterproof composite anti-wrinkle PE film. Background Technology

[0002] PE film, or polyethylene film, is a film made from polyethylene, a thermoplastic resin polymerized from ethylene. This gives PE film excellent flexibility, tensile strength, and chemical stability, making it suitable for various applications such as packaging, isolation, and protection.

[0003] Commonly used PE films are easily damaged by external heat during use, and stretching can also cause them to break, resulting in a short lifespan and low practicality. Chinese Patent Publication No. CN222099839U discloses a heat-insulating PE film that solves the above-mentioned problems through the cooperation of various components. However, in practical applications, the poor air permeability caused by heat insulation reduces the applicability of the PE film. Therefore, we propose a highly breathable and waterproof composite wrinkle-resistant PE film. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a highly breathable and waterproof composite anti-wrinkle PE membrane. By installing multiple supporting air rod membranes inside the air pores, the overall support of the thickened layer is increased, avoiding excessive softness that causes wrinkles and affects the breathability. Furthermore, the upper and lower ends of the supporting air rod membranes are set as arc-shaped structures, so that a small amount of water entering the air pores during use has an interception component. At the same time, the grooves allow the supporting air rod membranes to intercept water without affecting the breathability of the device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A highly breathable and waterproof composite wrinkle-resistant PE film includes a support mechanism, a main body mechanism installed at the upper end of the support mechanism, an assembly mechanism installed inside the main body mechanism, and a protective mechanism installed inside the main body mechanism at the upper end of the assembly mechanism.

[0007] The protective mechanism includes a thickened layer with air holes inside. A supporting air rod membrane is fixedly installed inside the air holes. The supporting air rod membrane has a tube groove inside. A bubble membrane is fixedly installed at the upper end of the thickened layer. A waterproof protrusion is fixedly provided at the upper end of the bubble membrane. By setting air holes, the device has good air permeability. Multiple supporting air rod membranes are installed inside the air holes to increase the overall support of the thickened layer and avoid excessive softness that causes wrinkles and affects the air permeability.

[0008] Furthermore, the support mechanism includes a support frame, a manually telescopic rod is fixedly installed at the lower inner end of the support frame, a movable frame is fixedly installed at the outer end of the manually telescopic rod, and a locking block is fixedly installed at the middle of the upper inner end of the movable frame. By setting the manually telescopic rod, the mechanism can be adjusted when connected to the main mechanism, making it suitable for main mechanisms of different specifications.

[0009] Furthermore, the main body includes a winding drum, the outer end of which is wound with the PE film body, making the PE film body easy to carry and neatly stored.

[0010] Furthermore, the combined mechanism includes a base film, a reinforcing layer at its upper end, a flexible fiber layer fixedly disposed at its upper end, and an electrostatic adsorption layer fixedly disposed at its lower end. The electrostatic adsorption layer has through-holes inside. The flexible fiber layer provides the device with good flexibility and makes it less prone to breakage when stretched. The electrostatic adsorption layer increases the device's fit.

[0011] Furthermore, the thickened layer is fixedly installed on the upper end of the flexible fiber layer, the air holes are distributed in an array inside the thickened layer, the upper and lower ends of the supporting air rod membrane are arc-shaped structures, and the tube grooves are distributed in a ring inside the supporting air rod membrane.

[0012] Furthermore, the bubble film is arranged in an array on the upper end of the thickened layer, the bubble film has a spherical structure, and the upper end of the waterproof protrusion has an arc-shaped structure.

[0013] Furthermore, the manual telescopic rod and the support frame have the same structure, and the locking block and the winding drum are compatible.

[0014] Furthermore, the base film is fixedly installed in the middle of the PE film body, and the lower end of the through hole is adapted to the waterproof protrusion.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By installing multiple supporting air rod membranes inside the air holes, the overall support of the thickened layer is increased, avoiding excessive softness that causes wrinkles and affects the breathability. At the same time, the upper and lower ends of the supporting air rod membranes are set as arc-shaped structures, so that a small amount of water entering the air holes during the use of the device has an interception component. The tube groove ensures that the supporting air rod membranes can intercept water without affecting the breathability of the device.

[0017] 2. The spherical bubble film lifts up the waterproof protrusion, allowing the air pores at the bottom of the waterproof protrusion to breathe while providing a certain degree of waterproofing. The bottom of the through hole is also designed to fit the waterproof protrusion, reducing the space required for the device to adhere when stacked and improving its adsorption properties.

A waterproof protrusion 406 is fixedly provided at the upper end of the bubble wrap 405. By setting the air holes 402, the device has good air permeability. Furthermore, by installing multiple supporting air rod membranes 403 inside the air holes 402, the overall support of the thickened layer 401 is increased, preventing it from being too soft and causing wrinkles that affect the air permeability.

By setting the manual telescopic rod 102, the mechanism can be adjusted when connected to the main body mechanism 2, making it suitable for main body mechanisms 2 of different specifications.

[0029] The main body 2 includes a winding drum 201, on the outer end of which a PE film body 202 is wound up. The winding drum 201 makes the PE film body 202 easy to carry and neatly stored.

[0030] The combined mechanism 3 includes a base film 301, a reinforcing layer 302 is provided at the upper end of the base film 301, a flexible fiber layer 303 is fixedly provided at the upper end of the reinforcing layer 302, and an electrostatic adsorption layer 304 is fixedly provided at the lower end of the base film 301.

[0031] The thickened layer 401 is fixedly installed on the upper end of the flexible fiber layer 303. The air holes 402 are distributed in an array inside the thickened layer 401.

[0035] Specific implementation process: This utility model is a highly breathable and waterproof composite wrinkle-resistant PE film. During installation, a flexible fiber layer 303 is first installed on the upper end of the base film 301, giving the device good flexibility and making it less prone to breakage during stretching. The interior of the flexible fiber layer 303 is permeable, not affecting the breathability of the lower reinforcing layer 302. Then, a thickened layer 401 is installed on the upper end of the flexible fiber layer 303. Air pores 402 are provided inside the thickened layer 401, giving the device good breathability. Multiple supporting air rod membranes 403 are installed inside the air pores 402 to increase the overall support of the thickened layer 401, preventing excessive softness from causing wrinkles that affect breathability. Simultaneously, it also... The upper and lower ends of the supporting air rod membrane 403 are designed with an arc-shaped structure, which allows a small amount of water entering the air hole 402 to be intercepted during use. The groove 404 ensures that the supporting air rod membrane 403 can intercept water without affecting the air permeability of the device. Finally, a spherical bubble membrane 405 is used on the upper end of the thickened layer 401 to lift the waterproof protrusion 406, so that the air hole 402 at the lower end of the waterproof protrusion 406 can be breathable while having a certain waterproof function. The various components of the device complement each other, and the lower end of the through hole 305 and the waterproof protrusion 406 are designed to fit together, so that the space for self-adhesion is reduced when the devices are stacked and the adsorption of the devices is improved.
