Description

Technical Field

[0001] The utility model relates to the technical field of curtains, and more specifically to a honeycomb curtain body and a honeycomb curtain capable of blocking light sources. Background Art

[0002] Honeycomb shades, also known as accordion shades or honeycomb shades, are a popular indoor shading product. The unique honeycomb structure of the honeycomb shade forms an air barrier inside each section of the shade. Since air is a poor conductor of heat, it can more effectively reduce the exchange of indoor and outdoor heat than conventional blinds. It has better thermal insulation effect, which can block external heat from entering in summer and reduce indoor heat loss in winter, thus contributing to energy conservation and emission reduction. In addition, the presence of the air barrier makes the honeycomb shade have better sound insulation effect, providing users with a quieter indoor environment.

[0003] The honeycomb blinds currently on the market have each curtain section of the curtain body only with a single-layer structure, and the material is generally non-woven fabric. Although the thermal conductivity of these fabrics is low, the fabric itself will conduct a certain amount of heat. A large number of curtain sections will have a more obvious negative impact on the overall thermal insulation effect of the honeycomb blinds. In addition, it cannot effectively reflect solar radiation or indoor thermal radiation, allowing a certain amount of solar radiation to penetrate into the room, causing the thermal insulation effect to be further affected. Therefore, the thermal insulation effect of the current honeycomb blinds in an environment with strong solar thermal radiation still has a lot of room for improvement. How to improve its thermal insulation effect has become a problem that needs to be solved urgently. Utility Model Content

[0004] In view of the above situation, in order to overcome the problem that each curtain section of the honeycomb blinds on the market is only a single-layer structure and the material is non-woven fabric or other synthetic fibers, the large number of curtain sections will conduct a large amount of heat into the room, and at the same time cannot effectively reflect solar radiation or indoor heat radiation, allowing a certain amount of solar radiation to penetrate into the room, resulting in a large room for improvement in its thermal insulation effect. The purpose of the utility model is to provide a honeycomb blind and its honeycomb blind that can effectively prevent its own heat from being conducted into the room and reflect solar radiation, and can provide users with better thermal insulation effect even in an environment with strong solar heat radiation.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A honeycomb curtain body capable of blocking light sources comprises a curtain body, wherein the curtain body has a plurality of curtain sections arranged in sequence from top to bottom, each curtain section comprises an inner lining base layer, an inner heat insulation layer and an outer heat insulation layer, a hollow air cavity is formed inside the inner lining base layer, the inner heat insulation layer is covered on the cavity wall of the air cavity, and the outer heat insulation layer is covered on the outer wall of the inner lining base layer.

[0007] Preferably, the outer heat insulation layer is coated on the outer wall of the inner lining base layer facing away from the indoor side.

[0008] Preferably, both the inner insulation layer and the outer insulation layer are aluminum insulation layers.

[0009] Preferably, the outer heat insulation layer is aluminum foil or an aluminide coating.

[0010] Preferably, the inner heat insulation layer is aluminum foil or an aluminide coating.

[0011] Preferably, the lining base layer is non-woven fabric.

[0012] Preferably, the lining base layer is aluminum foil.

[0013] Preferably, it comprises a window frame, the curtain body is located in the window frame, one end of the curtain body is connected to the transverse beam of the window frame, and the other end thereof can slide along the longitudinal beam of the window frame.

[0014] Preferably, it further comprises a counterweight block, which is connected to the curtain body, and sliders are provided at both ends of the counterweight block, which are slidably mounted on the longitudinal beams of the window frame.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] When the curtain body of the utility model is subjected to solar heat radiation, the outer insulation layer can prevent heat from being conducted along the surface of the inner lining base layer, and because air is a poor conductor of heat, the inner insulation layer can effectively prevent the air in the air cavity from heating up, reduce the flow of air in the air cavity, that is, reduce heat convection, and further prevent heat from being conducted into the room.

[0025] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed and specific directions, structures, and operations, and therefore should not be understood as limitations on the present utility model.

[0027] Embodiment 1:

[0028] like Figure 1 and Figure 2As shown, the utility model first relates to a honeycomb curtain body capable of blocking light sources, which comprises a curtain body body 1, wherein the curtain body body 1 has a plurality of curtain segments a1, each of which is arranged in sequence from top to bottom, so that the curtain body 1 has a certain length, and the number of curtain segments a1 is not particularly limited, so as to meet the size requirements of different window frames 2, each curtain segment a1 comprises an inner lining base layer 101, an inner heat insulation layer 102 and an outer heat insulation layer 103, wherein the inner lining base layer 101 is the skeleton of each curtain segment a1, and the inner lining base layer 102 is the outer heat insulation layer 103. A hollow air cavity 101a is formed inside the base layer 101. It can be understood that, as the curtain body 1 of the honeycomb curtain, each curtain section a1 presents a hexagonal honeycomb structure when the curtain body 1 is unfolded. The inner cavity of the honeycomb structure is the air cavity 101a. The air cavity 101a is connected to the external space through its two ends, so that the inside is filled with air. The inner heat insulation layer 102 is covered on the cavity wall of the air cavity 101a to cover the cavity wall of the air cavity 101a. The outer heat insulation layer 103 is covered on the inner cavity 101a. On the outer wall of the lining base layer 101, the outer wall of the inner lining base layer 101 is covered accordingly. The inner insulation layer 102 and the outer insulation layer 103 are made of insulation materials, and have a better effect of preventing heat transfer than the inner lining base layer 101. When the curtain body 1 of the utility model is subjected to solar heat radiation, the outer insulation layer 103 can prevent heat from being conducted along the surface of the inner lining base layer 101. Moreover, because air is a poor conductor of heat, under the action of the inner insulation layer 102, the temperature of the air in the air cavity 101a can be effectively prevented from rising, and the flow of air in the air cavity 101a can be reduced, that is, heat convection can be reduced, and heat can be further prevented from being conducted into the room. Especially in an external low temperature environment, it can also reduce indoor heat loss, keep the indoor warmth, and improve living comfort. At the same time, the inner lining base layer 101 wrapped by the inner insulation layer 102 and the outer insulation layer 103 can avoid direct penetration of sunlight, thereby significantly improving the heat insulation effect, and can keep the indoor temperature stable even in an environment with strong solar heat radiation.

[0029] Furthermore, the outer insulation layer 103 is arranged on the outer wall of the inner lining base 101 facing away from the indoor side, so that the side of the inner lining base 101 close to the indoor room is not covered by the outer insulation layer 103, that is, the inner lining base 101 is directly exposed to the indoor environment. Especially when the outer insulation layer 103 is selected as an aluminum insulation layer, it can avoid reflection and cause visual interference to users in the room, thereby significantly improving the user experience.

[0030] Furthermore, the inner insulation layer 102 and the outer insulation layer 103 are both aluminum insulation layers. The inner insulation layer 102 and the outer insulation layer 103 made of aluminum have a high reflectivity, so that when the curtain body 1 is subjected to solar heat radiation, most of the solar heat radiation can be reflected by the outer insulation layer 103, thereby reducing the conduction of heat through the surface of the outer insulation layer 103. In conjunction with the inner insulation layer 102, the temperature of the air in the air cavity 101a can be more effectively prevented, thereby improving the thermal insulation effect. Accordingly, in an external low temperature environment, the loss of indoor heat is further reduced.

[0031] Furthermore, the outer insulation layer 103 is an aluminum foil or an aluminide coating. The aluminum foil is a thin sheet made of pure aluminum or aluminum alloy, has a certain thickness and flexibility, and can be attached to the surface of the inner lining base 101. The aluminide coating can be a mixture of aluminum powder, aluminum paste or aluminum compounds and other resins, which is applied to the surface of the inner lining base 101 by spraying, brushing or dipping. Both the aluminum foil and the aluminide coating can provide excellent thermal insulation effect for the honeycomb curtain body of the utility model.

[0032] Furthermore, the inner insulation layer 102 is aluminum foil or an aluminide coating. Similarly, the aluminum foil can be attached to the wall of the air cavity 101a, and the aluminum coating can be applied to the wall of the air cavity 101a of the inner lining base layer 101 by spraying, brushing or dipping. Together with the outer insulation layer 103, the honeycomb curtain body of the utility model provides excellent thermal insulation effect.

[0033] Furthermore, the lining base layer 101 is a non-woven fabric. Since the non-woven fabric is a lightweight material, the use of the non-woven fabric as the lining base layer 101 can reduce the weight of the curtain body 1 and facilitate installation. At the same time, it also has a certain light-shielding and heat-insulating effect. Together with the inner insulation layer 102 and the outer insulation layer 103, it can stably maintain the indoor temperature. In addition, it also has the advantages of sound absorption, environmental protection, durability and low cost.

[0034] Embodiment 2:

[0035] This embodiment makes another optimized design based on the above-mentioned embodiment 1. The inner lining base 101 is aluminum foil. The inner lining base 101 of aluminum foil is combined with the inner insulation layer 102 and the outer insulation layer 103 which are aluminum insulation layers, so that the entire curtain section a1 is made of aluminum material and has a larger thickness, which is more effective in preventing solar heat radiation from penetrating into the room. At the same time, the air in the air cavity 101a is formed to make the honeycomb curtain body of the utility model have better heat insulation effect, which is more effective in reducing the loss of indoor heat in the external low temperature environment and keeping the indoor warmth.

[0036] like Figure 3 , Figure 4 and Figure 6As shown, the utility model also relates to a honeycomb curtain with the above-mentioned curtain body, which includes a window frame 2. Specifically, the window frame 2 is composed of two vertically opposed transverse beams and longitudinal beams located on both sides of the two transverse beams and connected to the first position thereof. The curtain body 1 is located in the window frame 2, one end of the curtain body 1 is connected to the transverse beams of the window frame 2, and the other end thereof can slide along the longitudinal beams of the window frame 2, and can switch between folded, semi-expanded and expanded states according to the sliding distance to achieve retraction and extension, so as to provide users with different shading and heat insulation effects.

[0037] like Figures 3 to 6 As shown, the counterweight block 3 is connected to the curtain body 1, and sliders 4 are provided at both ends of the counterweight block 3. The sliders 4 are slidably mounted on the two longitudinal beams of the window frame 2. The counterweight block 3 slides along the longitudinal beams through the sliders 4 to ensure that the curtain body 1 slides along a straight line for retraction and extension.

[0038] Combination Figures 1 to 6 When the honeycomb blind of the utility model is in use, the user can control the movement of the counterweight block 3 to drive the curtain body 1 to be retracted and extended, and different shading and thermal insulation effects are provided according to the sliding distance. When sunlight irradiates on the curtain body 1, the outer thermal insulation layer 103 coated with aluminum foil or aluminide reflects most of the solar heat radiation, reducing the heat conduction through the surface of the outer thermal insulation layer 103. At the same time, the inner thermal insulation layer 102 coated with aluminum foil or aluminide cooperates with the air in the air cavity 101a to effectively prevent the temperature of this part of the air from rising, reducing the flow of air in the air cavity 101a, that is, reducing heat convection, further preventing heat from being conducted into the room, providing excellent thermal insulation effect, especially in an external low temperature environment, it can also reduce the loss of indoor heat, keep the indoor warmth, and improve the living comfort. When the inner lining base layer 101 is aluminum foil, it can more effectively prevent solar heat radiation from penetrating into the room, providing users with better thermal insulation effect.

[0039] The above embodiments and descriptions are only for explaining the principle and the best embodiment of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
