Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to an adaptive heat-insulating curtain. Background Technology

[0002] Curtains are a common interior decoration item. In traditional use, the main purpose of curtains is to block light and protect indoor privacy. However, with the diversification of needs, curtains with additional functions such as dust prevention, sound absorption, heat insulation, radiation protection, or ultraviolet protection have gradually emerged.

[0003] Patent application CN201720136315.8 discloses an air-expanding heat-insulating curtain fabric, comprising: an outer heat-insulating layer and an inner soft layer. The outer heat-insulating layer is symmetrically arranged on the inner soft layer. Longitudinally spaced strip-shaped insulating portions are provided on both the outer heat-insulating layer and the inner soft layer, forming several cavities between them. Each cavity is filled with heat-insulating cotton strips, and each heat-insulating cotton strip contains an elliptical airbag filled with a heat-sensitive gas. In this technical solution, the heat-sensitive gas in the elliptical airbag expands upon heating, increasing the distance between the outer heat-insulating layer and the inner soft layer, reducing heat conduction between the outside and inside, and thus providing heat insulation. However, to achieve the heat insulation effect, the airbag needs to extend from the top to the bottom of the curtain. If the curtain is subjected to external impact, the airbag is easily punctured and leaks, rendering it insulated and causing the leaked gas to pose a safety hazard. Utility Model Content

[0004] To address the aforementioned issues, this invention provides an adaptive heat-insulating curtain. When heated, the curtain can form a heat-insulating cavity inside the curtain by inflating airbags, and the airbag configuration offers enhanced safety.

[0005] An adaptive thermal insulation curtain includes a curtain body and a thermal insulation component. The curtain body includes a plurality of curtain units arranged and connected along its width direction. Each curtain unit includes a first surface layer and a second surface layer. The two side edges of the first surface layer in the width direction are respectively connected to the two side edges of the second surface layer in the width direction. An inner cavity is formed between the first surface layer and the second surface layer. The thermal insulation component is disposed in the inner cavity. The thermal insulation component includes a first support strip and a second support strip extending along the height direction of the curtain body. A first expansion bladder and a second expansion bladder are disposed between the first support strip and the second support strip.

The two sides of the first expansion bladder are respectively connected to the upper ends of the first support strip and the second support strip, and the two sides of the second expansion bladder are respectively connected to the lower ends of the first support strip and the second support strip.

[0006] Furthermore, the curtain body also includes an upper edge banding strip and a lower edge banding strip respectively disposed at the upper and lower ends of the curtain unit, the upper edge banding strip and the lower edge banding strip forming a closed structure at the upper and lower ends of the inner cavity.

[0007] Furthermore, the curtain body also includes hanging holes, the positions of which correspond to the upper edge banding strip.

[0008] Furthermore, the curtain body also includes a hanging ring, which includes a cylindrical through-hole and limiting flanges at both axial ends of the through-hole, the through-hole passing through the hanging hole.

[0009] Furthermore, at least a portion of the first support strip is fixedly connected to the first surface layer, and at least a portion of the second support strip is fixedly connected to the second surface layer.

[0010] Furthermore, the portions of the first support strip near the upper and lower ends are fixedly connected to the first surface layer by stitching or adhesive material, and the portions of the second support strip near the upper and lower ends are fixedly connected to the second surface layer by stitching or adhesive material.

[0011] Furthermore, the heat insulation component also includes a first magnetic attractor and a second magnetic attractor.

[0015] The following beneficial effects can be achieved by applying this utility model:

[0016] 1. In this utility model, the heat-sensitive material inside the expansion bladder expands in volume when the temperature rises, thereby increasing the distance between the first and second support strips connected to the expansion bladder. The first and second support strips separate the first and second surface layers, increasing the distance between them and reducing heat exchange between them, thus providing a certain degree of heat insulation. Since the expansion bladder is located near the upper end of the first and second support strips, and the first and second support strips can protect the expansion bladder from direct impact and puncture, the expansion bladder can be made of elastic plastic material. When the first and second support strips are impacted, they can be cushioned by their own bending deformation, reducing the impact force received by the expansion bladder.

[0017] 2. In some embodiments of this utility model, the first support strip and the second support strip are respectively provided with a first magnetic attractant and a second magnetic attractant. When the temperature is low and the expansion bladder contracts, the first magnetic attractant and the second magnetic attractant adhere to each other, so that the distance between the first surface layer and the second surface layer is kept small, which is beneficial to improving the breathability of the curtain.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model. Example

[0023] Reference Figures 1-3One embodiment of the present invention provides an adaptive thermal insulation curtain, which includes a curtain body 1 and a thermal insulation component 2;

[0024] The curtain body 1 includes a plurality of curtain units 11 arranged and connected along its width direction. Each curtain unit includes a first surface layer 111 and a second surface layer 112. The two side edges of the first surface layer in the width direction are respectively connected to the two side edges of the second surface layer in the width direction. An inner cavity 113 is formed between the first surface layer and the second surface layer. In order to improve the overall integrity of the curtain, in this embodiment, the curtain body includes a first curtain fabric and a second curtain fabric stacked together. The first curtain fabric and the second curtain fabric are connected by a plurality of stitching lines 16. The stitching lines 16 are arranged along... The curtain body 1 extends in the height direction, and several stitching lines 16 are arranged at intervals along the width direction of the curtain body 1, so that adjacent stitching lines 16 form the curtain unit 11; an upper edge banding strip 12 and a lower edge banding strip 13 are respectively provided at the upper and lower ends of the curtain unit 11. The upper edge banding strip 12 and the lower edge banding strip 13 are made of a thicker and more wear-resistant fabric than the first curtain fabric and the second curtain fabric, so as to reduce wear at the bottom of the curtain and deformation of the upper hanging part of the curtain. Furthermore, the upper edge banding strip and the lower edge banding strip seal the upper and lower ends of the inner cavity 113, so as to... The thermal insulation component 2 is encapsulated, and a hanging hole 14 is provided at the upper edge banding. The hanging hole 14 is used to hang curtains. Taking some existing curtain installation methods as an example, there is usually a track on the upper side of the window, and several hangers are slidably installed in the track. The bottom of the hangers is provided with hooks. The hooks are passed through the hanging hole 14 to hang the curtains. The curtains can be opened and closed by sliding the hangers in the track. In order to further improve the durability of the main hanging part of the curtain, a hanging ring 15 can be provided at the hanging hole. The hanging ring 15 includes a cylindrical through part and a part disposed at the through part. The limiting flanges at both ends of the axial direction protrude, and the through-hole 14 allows the hanger to directly contact the hanging ring. The rigid structure of the hanging ring reduces the deformation of the curtain at the hanging hole. The hanging ring 15 is typically made of metal or high-strength engineering plastic. In some embodiments, to further improve the heat insulation effect of the curtain, a low thermal conductivity layer can be provided on the inner surfaces of the first and second layers. For example, the low thermal conductivity layer can be formed by a coating with low thermal conductivity or by a pile structure. The pile structure can utilize the stagnant air inside to reduce the overall thermal conductivity.

[0025] The heat insulation component 2 is disposed in the inner cavity 113, and includes a first support strip 21 and a second support strip 22 extending along the height direction of the curtain body 1. A first expansion bladder 23 and a second expansion bladder 24 are disposed between the first support strip 21 and the second support strip 22. The two sides of the first expansion bladder are respectively bonded to the upper ends of the first and second support strips, and the two sides of the second expansion bladder are respectively bonded to the lower ends of the first and second support strips. The first and second support strips are respectively bonded to the first surface layer 111 and the second surface layer 112. The first expansion bladder 23 and the second expansion bladder 24 are filled with a heat-sensitive material whose volume is related to temperature. In this embodiment, in order to improve the volume difference before and after expansion, a gas-liquid two-phase material is used for the heat-sensitive material. At lower temperatures, the heat-sensitive material is in a liquid state, and the first and second expansion bladders have smaller volumes. At higher temperatures, the heat-sensitive material is in a liquid state. Currently in a gaseous state, the first and second expansion bladders have relatively large volumes. In practical applications, the vaporization temperature of the heat-sensitive material can generally be set at around 30°C, but other standards can be used depending on the requirements. The first and second support strips are made of elastic plastic. When the first or second support strip is impacted by an external force, it can undergo elastic bending deformation to form a buffer effect and reduce the impact on the first and second expansion bladders. A first magnetic attractor 211 is provided near the upper and lower ends of the first support strip, and a second magnetic attractor 221 is provided near the upper and lower ends of the second support strip. The positions of the first and second magnetic attractors correspond and their magnetic poles attract each other. The first and second expansion bladders are located exactly between the first and second magnetic attractors. The magnetic force between the first and second magnetic attractors should not be set too strong to prevent hindering the expansion of the expansion bladders.

[0026] In this invention, the heat-sensitive material inside the expansion bladder expands in volume when the temperature rises, thereby increasing the distance between the first and second support strips connected to the expansion bladder. The first and second support strips spread the first and second surface layers apart, increasing the distance between them and reducing heat exchange, thus providing a certain degree of heat insulation. When the temperature is low and the expansion bladder contracts, the first and second magnetic components adhere to each other, keeping the distance between the first and second surface layers small, which helps improve the breathability of the curtains and achieves a certain degree of adaptive adjustment.

[0027] The system includes several curtain units arranged and connected along its width. Each curtain unit includes a first surface layer and a second surface layer. The two side edges of the first surface layer in the width direction are respectively connected to the two side edges of the second surface layer in the width direction. An inner cavity is formed between the first surface layer and the second surface layer. The heat insulation component is disposed in the inner cavity. The heat insulation component includes a first support strip and a second support strip extending along the height direction of the curtain body. A first expansion bladder and a second expansion bladder are disposed between the first support strip and the second support strip. The first expansion bladder and the second expansion bladder are filled with a heat-sensitive material whose volume is related to temperature. The two expansion bladders are respectively disposed near the upper end and the lower end of the support strip.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
