Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural facility technology, and more specifically to a bubble-type airless heat-insulating film for greenhouses. Background Technology
[0002] Thermal insulation film is a type of heat insulation material used in buildings, greenhouses, sheds, and other similar applications. It effectively maintains the internal temperature and reduces heat loss. It is typically made of polymer materials and possesses excellent heat insulation, thermal insulation, UV protection, and anti-aging properties.
[0003] However, traditional greenhouse insulation films mostly use single-layer or double-layer structures, which have limited insulation effects, especially in cold seasons or areas with large diurnal temperature variations, making it difficult to meet the temperature requirements for crop growth. Existing technology has led some greenhouses to attempt to improve insulation performance using inflatable double-layer film structures, but these structures require additional inflation equipment, increasing costs and maintenance difficulties. Furthermore, the insulation effect of inflatable structures significantly decreases when air pressure is insufficient or equipment malfunctions.
[0004] To address these issues, we propose a bubble-type, airless insulation film for greenhouses. Utility Model Content
[0005] The purpose of this invention is to address the problem that in the existing technology, some greenhouses attempt to improve their heat preservation performance through an inflatable double-layer film structure, but this type of structure requires additional inflation equipment, which increases costs and maintenance difficulty. In addition, the heat preservation effect of the inflatable structure will significantly decrease when the air pressure is insufficient or the equipment malfunctions. Therefore, this invention provides a bubble-type airless heat preservation film for greenhouses.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A bubble-type airless thermal insulation film for greenhouses includes a sealing frame and a thermal insulation film body. The thermal insulation film body is fitted inside the sealing frame. The thermal insulation film body includes a base film, a bubble layer on top of the base film, a functional layer on top of the bubble layer, a protective layer on top of the functional layer, and edge fixing structures at the four corners of the sealing frame.
[0008] As a further description of the above technical solution, the bubble layer includes an upper film and a lower film, and a plurality of uniformly distributed bubble units are disposed between the upper film and the lower film, with thermal insulation filler filling between adjacent bubble units.
[0009] As a further description of the above technical solution, the individual bubble unit is filled with inert gas, the bubble unit is hemispherical in shape, the height of the bubble unit is 5-20 mm, the diameter is 10-50 mm, and the distance between adjacent bubble units is 5-15 mm.
[0010] As a further description of the above technical solution, both the base film and the protective layer are PO films.
[0011] As a further description of the above technical solution, the functional layer includes an anti-drip layer and an anti-ultraviolet layer, which are integrally formed with the bubble layer through a co-extrusion process.
[0012] As a further description of the above technical solution, the edge fixing structure includes movable buckles and fixing straps disposed at the four corners of the sealed frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In use, this invention involves laying the insulation film on the greenhouse frame and securing it with an edge fixing structure. The edge fixing structure uses fixing straps and movable buckles for easy and quick installation and disassembly, offering flexible installation and convenient use. Both the base film and the protective layer are made of PO film, which has high light transmittance and weather resistance. Inert gas is filled inside the insulation filler in the bubble layer to further improve heat insulation performance, significantly enhancing the greenhouse's insulation performance. Simultaneously, the insulation filler is independently distributed, so even if some bubbles are damaged, the overall insulation performance remains intact. It is pressure-resistant and durable, requiring no additional inflation equipment, reducing costs and maintenance difficulty. The functional layer integrates anti-drip and UV-resistant functions, effectively extending the service life of the insulation film while improving light transmittance, thus enhancing the device's practicality.

[0019] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.
[0020] This utility model provides a bubble-type, air-inflatable, heat-insulating film for greenhouses. Please refer to [link / reference]. Figure 1-3 As shown, it includes a sealing frame 1 and a thermal insulation film body 2. The thermal insulation film body 2 is fitted inside the sealing frame 1. The thermal insulation film body 2 includes a base film 21. A bubble layer 22 is provided on the top of the base film 21. A functional layer 23 is provided on the top of the bubble layer 22. A protective layer 24 is provided on the top of the functional layer 23. An edge fixing structure is provided at each of the four corners of the sealing frame 1.
[0021] In this embodiment, the bubble layer 22 is integrated with the base film 21, functional layer 23, and protective layer 24, making installation and use convenient. The insulation film is laid on the greenhouse frame and fixed by the edge fixing structure, which uses fixing straps 4 and movable buckles 3 for easy installation and disassembly. The base film 21 and protective layer 24 are both made of PO film, which has high light transmittance and weather resistance. By filling the insulation filler 224 in the bubble layer 22 with inert gas, the heat insulation performance is further improved, which can significantly improve the heat insulation performance of the greenhouse. At the same time, the insulation filler 224 is independently distributed, so even if some bubbles are damaged, the overall heat insulation performance can still be maintained. The functional layer 23 integrates anti-drip and anti-ultraviolet functions, effectively extending the service life of the insulation film and improving light transmittance.
[0022] Furthermore, the bubble layer 22 includes an upper film 221 and a lower film 222. A plurality of uniformly distributed bubble units 223 are disposed between the upper film 221 and the lower film 222. The spaces between adjacent bubble units 223 are filled with thermal insulation filler 224. In use, by filling the thermal insulation filler 224 in the bubble layer 22 with inert gas, the thermal insulation performance is further improved, which can significantly improve the thermal insulation performance of the greenhouse. At the same time, the thermal insulation filler 224 is independently distributed, so even if some bubbles are damaged, the overall thermal insulation performance can still be maintained. The thermal insulation performance of the insulation film is further improved by filling the bubble units 223.
[0023] Furthermore, each bubble unit 223 is filled with inert gas. The bubble unit 223 is hemispherical in shape, with a height of 5-20 mm and a diameter of 10-50 mm. The spacing between adjacent bubble units 223 is 5-15 mm. When in use, the inert gas further improves the heat insulation performance, thereby enhancing the heat preservation performance of the greenhouse.
[0024] Furthermore, both the base layer 21 and the protective layer 24 are PO films, which have good weather resistance and anti-aging properties when in use.
[0025] Furthermore, the functional layer 23 includes an anti-drip layer and an anti-UV layer, which are integrally formed with the bubble layer 22 through a co-extrusion process. In use, the anti-drip layer is achieved by coating the surface with an anti-fogging agent, and the anti-UV layer is achieved by adding an ultraviolet absorber, thereby extending the service life of the insulation film and improving light transmittance.
[0026] Furthermore, the edge fixing structure includes movable buckles 3 and fixing straps 4 set at the four corners of the sealing frame 1. In use, the movable buckles 3 and fixing straps 4 make it easy to snap together, adapt to greenhouse frames of different sizes, and facilitate installation and disassembly.
[0027] The working principle of this utility model is as follows: When in use, the insulation film is laid on the greenhouse frame and fixed by the edge fixing structure. The edge fixing structure adopts the fixing strap 4 and the movable buckle 3, which is convenient for installation and disassembly and easy to use. The base film 21 and the protective layer 24 are both made of PO film, which has high light transmittance and weather resistance. By filling the insulation filler 224 in the bubble layer 22 with inert gas, the heat insulation performance is further improved, which can significantly improve the heat insulation performance of the greenhouse. At the same time, the insulation filler 224 is independently distributed, so even if some bubbles are damaged, the overall heat insulation performance can still be maintained. The functional layer 23 integrates anti-drip and anti-ultraviolet functions, which effectively extends the service life of the insulation film and improves light transmittance.
[0028] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
