[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0030] The spring core 100 of the present invention comprises a first core layer 1 and a second core layer 2. The first core layer 1 comprises a plurality of pocket spring strings 11. The second core layer 2 is arranged in the height direction of the first core layer 1 (e.g. Figure 1 The second core layer 2 includes a cloth cover 21 and a plurality of elastic blocks 22, the cloth cover 21 has a plurality of chambers 211 spaced apart from each other, the elastic blocks 22 are arranged in the chambers 211, the cloth cover 21 includes a first non-woven fabric 212 and a second non-woven fabric 213, the first non-woven fabric 212 of the second core layer 2 located at the same end of the height direction of the first core layer 1 is the same non-woven fabric, and the second non-woven fabric 213 of the second core layer 2 located at the same end of the height direction of the first core layer 1 is the same non-woven fabric.

[0031] Specifically, if Figures 1-6 As shown, the plurality of pocket spring strings 11 are arranged in sequence in the front-to-back direction, and the front end of one pocket spring string 11 of two adjacent pocket spring strings 11 is connected to the rear end of the other pocket spring string 11, thereby achieving connection of the pocket spring strings 11. For example, the plurality of pocket spring strings 11 are bonded together.

[0032] The second core layer 2 is arranged on at least one of the upper and lower sides of the first core layer 1. When there is one second core layer 2, the second core layer 2 is arranged on the upper side of the first core layer 1, or the second core layer 2 is arranged on the lower side of the first core layer 1. It can be understood that the second core layer 2 in the present application is not limited to one. For example, there are multiple second core layers 2, and multiple second core layers 2 are located on the upper side of the first core layer 1. The multiple second core layers 2 are arranged in sequence in the up and down directions and are connected to the first core layer 1, that is, the multiple second core layers 2 and the first core layer 1 are connected in sequence in the up and down directions. In addition, the present application is not limited to this. For example, the multiple second core layers 2 can also be located on the lower side of the first core layer 1.

[0033] There are two second core layers 2, and one second core layer 2 is located above the first core layer 1, and the other second core layer 2 is located below the first core layer 1. It is understandable that in the present application, the second core layer 2 located on the upper and lower sides of the first core layer 1 is not limited to one. For example, there are multiple second core layers 2 above the first core layer 1 and multiple second core layers 2 below the first core layer 1.

[0034] Compared with the arrangement in the related art in which springs 112 of different stiffness are installed in the same cloth bag 111, the spring core 100 of the embodiment of the utility model is provided with a plurality of chambers 211 spaced apart from each other in the cloth cover 21, and the elastic blocks 22 are installed in the chambers 211 to form a second core layer 2. The second core layer 2 is provided at at least one end in the height direction of the first core layer 1. When the spring core 100 is under pressure, the elastic blocks 22 of the second core layer 2 are compressed first, and the bagged spring string 11 of the first core layer 1 is compressed later. By providing a plurality of elastic blocks 22 respectively wrapped in different chambers 211 of the cloth cover 21, the bearing capacity of the second core layer 2 is improved, thereby improving the comfort of the spring core 100.

[0035] Furthermore, since the multiple elastic blocks 22 are respectively wrapped in different chambers 211, the elastic blocks 22 are prevented from being directly connected to the elastic blocks 22, so that the multiple elastic blocks 22 are independent of each other. When some elastic blocks 22 are compressed, it will not affect the status of other elastic blocks 22, and the elastic blocks 22 have better support.

[0036] Furthermore, the second core layer 2 of this embodiment is formed by two non-woven fabrics facing each other in the up and down directions and partially connected to form a plurality of cavities, thereby improving the production efficiency of the second core layer 2.

[0037] In some embodiments, the first non-woven fabric 212 and the second non-woven fabric 213 are opposite to each other in the height direction of the first core layer 1, the first non-woven fabric 212 has multiple first connecting parts, and the second non-woven fabric 213 has multiple second connecting parts. The multiple second connecting parts and the multiple first connecting parts are connected to each other one by one to form multiple connecting parts 23, and the chamber 211 is formed between two adjacent connecting parts 23.

[0038] Specifically, if Figure 1 and Figure 4 As shown, the first non-woven fabric 212 and the second non-woven fabric 213 are arranged relative to each other in the up and down directions, the first non-woven fabric 212 has a plurality of first connecting parts arranged at intervals, and the second non-woven fabric 213 has a plurality of second connecting parts arranged at intervals, and the plurality of first connecting parts and the plurality of second connecting parts are connected one-to-one to form a plurality of connecting points 23, so that a plurality of chambers 211 separated from each other are formed between the first non-woven fabric 212 and the second non-woven fabric 213.

[0039] Optionally, the first connecting portion of the first non-woven fabric 212 and the second connecting portion of the second non-woven fabric 213 are ultrasonically welded to ensure a firm and reliable connection.

[0040] In some embodiments, the first non-woven fabric 212 is closer to the first core layer 1 than the second non-woven fabric 213 , and one end of the first non-woven fabric 212 away from the second non-woven fabric 213 is bonded to one end of the first core layer 1 in the height direction.

[0041] Specifically, if Figure 1 As shown, when the second core layer 2 is located above the first core layer 1, the first non-woven fabric 212 is located below the second non-woven fabric 213, and the lower end of the first non-woven fabric 212 is bonded to the upper end of the first core layer 1 to achieve the connection between the first core layer 1 and the second core layer 2.

[0042] It can be understood that when the second core layer 2 is located below the first core layer 1 , the first non-woven fabric 212 is located above the second non-woven fabric 213 , and the upper end of the first non-woven fabric 212 is bonded to the lower end of the first core layer 1 .

[0043] For example, the first core layer 1 and the first non-woven fabric 212 are bonded together by hot melt adhesive.

[0044] In some embodiments, the plurality of elastic blocks 22 are divided into a plurality of groups of elastic blocks 22, and the plurality of groups of elastic blocks 22 are arranged in a first direction (eg, Figure 1 In the left and right directions shown in FIG, each group of elastic blocks 22 includes a plurality of elastic blocks 22 in the second direction (as shown in FIG. Figure 3 The elastic blocks 22 are arranged at intervals in the front-to-back direction (as shown in the figure), and the second direction is perpendicular to the first direction and the height direction of the first core layer 1.

[0045] In this embodiment, multiple first connecting parts on the first non-woven fabric 212 and multiple second connecting parts on the second non-woven fabric 213 are welded one by one to form multiple chambers 211 arranged in a matrix, that is, two adjacent chambers 211 in the left and right directions and in the front and back directions are formed by welding the first non-woven fabric 212 and the second non-woven fabric 213, and the multiple chambers 211 are arranged one by one with the multiple elastic blocks 22. The multiple elastic blocks 22 are respectively installed in the multiple chambers 211 to improve the production efficiency of the second core layer 2.

[0046] In some embodiments, each bagged spring string 11 extends along a first direction and includes a cloth bag 111 and a plurality of springs 112. The inner cavity of the cloth bag 111 of each bagged spring string 11 is divided into two sections along the first direction (e.g., Figure 1 The plurality of bag chambers 1111 are spaced apart in the left and right directions (as shown), the springs 112 are arranged in the bag chambers 1111, and the plurality of bagged spring strings 11 are connected in sequence in the second direction.

[0047] Specifically, if Figure 3 and Figure 5 As shown, the pocket spring string 11 extends in the left-right direction, and multiple pocket spring strings 11 are arranged in sequence in the front-to-back direction. The cloth bag 111 of each pocket spring string 11 has multiple pocket chambers 1111 spaced apart in the left-right direction. The multiple pocket chambers 1111 are arranged in a one-to-one correspondence with the multiple springs 112, and the multiple springs 112 are respectively installed in the multiple pocket chambers 1111. For example, the cloth bag 111 of each first core layer 1 is separated into multiple pocket chambers 1111 by welding.

[0048] When the first core layer 1 and the second core layer 2 are connected, the cloth bag 111 of the first core layer 1 is connected to the cloth cover 21 of the second core layer 2, that is, the lower end of the first non-woven fabric 212 is bonded to the upper end of the cloth bag 111, so as to avoid the elastic block 22 being directly connected to the spring 112, thereby reducing the friction between the elastic block 22 and the spring 112, and reducing the noise during the movement of the elastic block 22 and the spring 112, thereby improving the quality of the spring core 100.

[0049] In some embodiments, in a projection plane perpendicular to the height direction of the first core layer 1 , a projection area of ​​the elastic block 22 is smaller than or equal to a projection area of ​​the spring 112 .

[0050] Specifically, the projected area of ​​the elastic block 22 may be smaller than the projected area of ​​the spring 112, or the projected area of ​​the elastic block 22 may be equal to the projected area of ​​the spring 112, or the projected area of ​​a portion of the elastic block 22 may be smaller than the projected area of ​​the spring 112, while the projected area of ​​another portion of the elastic block 22 may be equal to the projected area of ​​the spring 112. In this embodiment, the projected area of ​​the elastic block 22 is set to be smaller than the projected area of ​​the spring 112.

[0051] In this embodiment, by setting the projection area of ​​the elastic block 22 to be less than or equal to the projection area of ​​the spring 112, elastic blocks 22 with different projection areas can be designed according to different support requirements, so that the elastic block 22 can provide more uniform support, reduce local over-support and insufficient support, and improve comfort.

[0052] For example, the elastic block 22 may be a cube, a cuboid, or a cylinder.

[0053] Of course, in other embodiments, the projected area of ​​the elastic block 22 may also be set to be larger than the projected area of ​​the spring 112 . For example, the elastic block 22 is a cube, and the side length of the cube is set to be the same as the diameter of the spring 112 .

[0054] In some embodiments, a dimension of the second core layer 2 in the height direction of the first core layer 1 is smaller than a dimension of the first core layer 1 in the height direction of the first core layer 1 .

[0055] Specifically, if Figure 1 As shown, the second core layer 2 is arranged above the first core layer 1. In this embodiment, the size of the second core layer 2 in the up and down directions is limited to be smaller than the size of the first core layer 1 in the up and down directions, ensuring that the first core layer 1 provides basic support and the second core layer 2 provides better comfort and support.

[0056] It is understandable that when the size of the second core layer 2 in the vertical direction is larger than that of the first core layer 1 in the vertical direction, additional pressure will be added to the first core layer 1 , affecting the quality of the spring core 100 .

[0057] In some embodiments, the dimension of the spring 112 in the height direction of the first core layer 1 is 120 mm-300 mm, and the dimension of the elastic block 22 in the height direction of the first core layer 1 is 25 mm-50 mm.

[0058] In this embodiment, by limiting the sizes of the spring 112 and the elastic block 22 in the vertical direction to specific ranges, it is further ensured that the spring 112 provides basic support and the elastic block 22 provides better comfort and support.

[0059] For example, the vertical dimension of the spring 112 refers to the dimension of the spring 112 when installed in the cloth bag 111 under pressure.

[0060] For example, the dimensions of the elastic block 22 in the height direction of the first core layer 1 are 25mm, 30mm, 35mm, 40mm, 45mm, and 50mm. The dimensions of the spring 112 in the height direction of the first core layer 1 are 120mm, 150mm, 225mm, 260mm, 280mm, and 300mm.

[0061] Of course, in other embodiments, the size of the spring 112 in the height direction of the first core layer 1 can also be set to other values ​​outside the range of 120mm-300mm, and the size of the elastic block 22 in the thickness direction of the height of the first core layer 1 can also be set to a value other than 25mm-50mm.

[0062] In some embodiments, the elastic block 22 is a sponge block. By using a sponge block as the elastic block 22, different types of sponges are available, allowing for different needs to be met. By replacing different sponges, different rebound effects can be achieved. Furthermore, aromatherapy materials or mite removal materials can be added to the sponge block to meet different needs and enhance diversity.

[0063] Furthermore, since the weight of the sponge block is less than the weight of the spring 112, by setting the elastic block 22 as a sponge block, it is beneficial to reduce weight.

[0064] The mattress according to the embodiment of the present invention includes the spring core 100 according to the above embodiment.

[0065] The mattress of the embodiment of the present invention can improve the bearing capacity and comfort of the mattress due to the use of the spring core 100 of the above embodiment.

[0066] It is understandable that the spring core 100 can be used in mattresses as well as sofas.
