Description

Technical Field

[0001] This utility model relates to the field of bed core technology, specifically to an environmentally friendly spring assembly for the cushioning and comfort layer of a mattress. Background Technology

[0002] A mattress is an item placed between the human body and the bed to ensure that consumers get healthy and comfortable sleep. There are many types of mattresses, and mattresses made of different materials can bring different sleep effects. A mattress includes a core, fabric, and edge protectors. The core includes springs and foam. With the continuous progress of material civilization and technology, the types of mattresses used by modern people have gradually become more diversified, mainly including spring mattresses, palm mattresses, latex mattresses, water mattresses, back support mattresses, air mattresses, and magnetic mattresses.

[0003] A mattress core consists of spring assemblies and foam. Existing spring assemblies are generally individual pocket springs. These individual pocket springs need to be glued to the inside of the mattress with hot melt adhesive to prevent them from shifting during use. However, using hot melt adhesive can produce formaldehyde, which can affect human health. Secondly, since individual pocket springs are generally wrapped in non-woven fabric, which has good breathability but poor durability, if a certain part of the non-woven fabric is frequently deformed, the non-woven fabric is prone to wear and tear. This can cause the spring to detach from the non-woven fabric and damage the foam, thus reducing the lifespan of the mattress. Utility Model Content

[0004] This utility model provides an environmentally friendly spring assembly for the cushioning comfort layer of a mattress. It has the advantages of addressing the shortcomings of existing spring assemblies, such as poor environmental friendliness and the susceptibility of the non-woven fabric wrapping the springs to damage. It also solves the problems mentioned in the background art, such as the use of hot melt adhesive which produces formaldehyde and affects human health. Furthermore, since individually pocketed springs are generally wrapped in non-woven fabric, which has good breathability but poor durability, the non-woven fabric is prone to wear and tear when it is frequently deformed in a certain position. This can cause the spring to detach from the non-woven fabric and damage the foam, thus reducing the lifespan of the mattress.

[0005] This utility model provides the following technical solution: an environmentally friendly spring assembly for a mattress cushioning comfort layer, comprising:

[0006] Non-woven bags;

[0007] A number of iron rings, which together form a spring, are disposed inside the non-woven bag;

[0008] A number of limiting rings are provided, the number of which is equal to the number of iron rings. One end of each iron ring passes through the axis of the limiting ring, and one end of each limiting ring is connected to the inner wall of the non-woven bag.

[0009] A breathable layer is provided at its lower end, and the upper end of the nonwoven bag is used to insert into the interior of the first groove.

[0010] As an optional solution for the environmentally friendly spring assembly for the mattress cushioning comfort layer of this utility model, wherein: the upper and lower ends of the non-woven bag are provided with piston cylinders, and the diameter of the piston cylinders is adapted to the inner diameter of the first groove;

[0011] The outer surface of the piston cylinder is provided with a first oblique hole for jetting.

[0012] As an optional solution for the environmentally friendly spring assembly for the mattress cushioning comfort layer of this utility model, at least two support strips are also installed at the upper end of the non-woven bag, and the upper end of the support strips is connected to the piston cylinder.

[0013] A piston cavity is formed between the non-woven bag and the piston cylinder, and the piston cavity is connected to the first oblique hole.

[0014] As an optional solution for the environmentally friendly spring assembly for the mattress cushioning comfort layer of this utility model, wherein: the outer surface of the piston cylinder is further provided with a second oblique hole;

[0015] The injection direction of the first oblique hole is opposite to that of the second oblique hole.

[0016] As an optional solution for the environmentally friendly spring assembly for the mattress cushioning comfort layer of this utility model, it further includes a support layer and a second groove. The upper end of the support layer is provided with a second groove, and the piston cylinder at the lower end of the non-woven bag is used to insert into the interior of the second groove.

[0017] As an optional solution for the environmentally friendly spring assembly for the mattress cushioning comfort layer described in this utility model, wherein: the diameter of the spring is smaller than the inner diameter of the non-woven bag;

[0018] One end of the limiting ring is used to stretch the non-woven bag and deform it.

[0019] As an optional solution for the environmentally friendly spring assembly for the mattress cushioning comfort layer of this utility model, wherein: the breathable layer is made of latex, and a plurality of first ventilation holes are provided on the breathable layer, the first ventilation holes penetrating the breathable layer;

[0020] The support layer is made of cotton and linen, and a second vent hole is provided on the support layer, which penetrates the support layer.

[0021] This utility model has the following beneficial effects:

[0022] 1. The mattress cushioning comfort layer uses an environmentally friendly spring assembly to insert the non-woven fabric bag into the first groove, thus eliminating the need for hot melt adhesive to connect it to the inside of the mattress, improving environmental protection. When the first groove is under pressure, it compresses the iron ring, causing the iron ring to slide downwards. The iron ring drives the limiting ring at one end to slide downwards, and the limiting ring pulls the non-woven fabric bag connected to it to deform downwards. This achieves the effect that after the iron ring is triggered, the corresponding limiting ring pulls the connected non-woven fabric bag to deform, thereby reducing the impact of deformation on the non-woven fabric bags in other areas and improving the service life of the non-woven fabric bags.

[0023] 2. The mattress cushioning comfort layer uses an environmentally friendly spring assembly. Air from inside the non-woven fabric bag is injected through the first oblique hole set on the outer surface of the piston cylinder, which improves the overall breathability. The flowing air also agitates the inside of the mattress core. When there is moisture inside the mattress core, the flowing air can carry away some of the moisture and quickly remove it from the mattress core, thereby improving the comfort of use.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1-2 One type of environmentally friendly spring assembly for mattress cushioning comfort layer includes:

[0031] 1 non-woven bag;

[0032] Several iron rings 2 form a spring, and the spring is set inside the non-woven bag 1;

[0033] Set up a number of limiting rings 3 equal to the number of iron rings 2. One end of the iron ring 2 passes through the axis of the limiting ring 3, and one end of the limiting ring 3 is connected to the inner wall of the non-woven bag 1.

[0034] The breathable layer 4 has a first groove 5 at its lower end, and the upper end of the nonwoven bag 1 is used to insert into the interior of the first groove 5.

[0035] The mattress core consists of spring components and foam. Existing spring components are generally individually pocketed springs. These individually pocketed springs need to be glued to the inside of the mattress with hot melt adhesive to prevent them from shifting during use. However, the use of hot melt adhesive can produce formaldehyde, which can affect human health. Secondly, since individually pocketed springs are generally wrapped in non-woven fabric, which has good breathability but poor durability, the non-woven fabric is prone to wear and tear when it deforms frequently in a certain area. This can cause the spring to detach from the non-woven fabric and damage the foam, thus reducing the lifespan of the mattress.

[0036] according to Figure 1 and Figure 2 As shown, the non-woven bag 1 is inserted into the first groove 5, thus eliminating the need for hot melt adhesive to connect it to the inside of the mattress, improving environmental protection. When the first groove 5 is under force, it compresses the iron ring 2, causing the iron ring 2 to slide downwards. The iron ring 2 drives the limiting ring 3 at one end to slide downwards, and the limiting ring 3 pulls the non-woven bag 1 connected to it to deform downwards. This achieves the effect that after the iron ring 2 is triggered, the corresponding limiting ring 3 pulls the connected non-woven bag 1 to deform, thereby reducing the impact of deformation on other areas of the non-woven bag 1 and improving the service life of the non-woven bag 1.

[0037] Example 2

[0038] This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figures 1-2 The nonwoven bag 1 is provided with piston cylinders 8 at both the top and bottom ends, and the diameter of the piston cylinders 8 is matched with the inner diameter of the first groove 5.

[0039] The outer surface of the piston cylinder 8 is provided with a first oblique hole 11 for jet injection;

[0040] Furthermore, the nonwoven bag 1 has round holes at both the top and bottom ends, which are connected to the nonwoven bag 1.

[0041] according to Figure 2As shown, although the non-woven bag 1 has good air permeability, a large amount of air cannot pass through it instantly. Furthermore, because the iron ring 2 is compressed, it pulls the matching portion of the non-woven bag 1 downwards, causing the air permeability of some stacked non-woven bags 1 to decrease again. Thus, utilizing the air inside the non-woven bag 1, according to... Figure 2 As shown, when the non-woven bag 1 is compressed, the air inside the non-woven bag 1 diffuses to the surroundings. Piston cylinders 8 are installed at the upper and lower ends of the non-woven bag 1. Air inside the non-woven bag 1 is injected through the first oblique hole 11 on the outer surface of the piston cylinder 8, thereby improving the overall air permeability. The flowing air also agitates the inside of the bed core. When there is moisture inside the bed core, the flowing air can carry away some of the moisture and quickly leave the bed core, thereby improving the comfort of use.

[0042] Example 3

[0043] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figures 1-3 At least two support bars 9 are also installed at the upper end of the non-woven bag 1, and the upper end of the support bars 9 is connected to the piston cylinder 8.

[0044] A piston chamber 10 is formed between the non-woven bag 1 and the piston cylinder 8, and the piston chamber 10 is connected to the first oblique hole 11.

[0045] The outer surface of the plug tube 8 is also provided with a second oblique hole 12;

[0046] The injection direction of the first oblique hole 11 is opposite to that of the second oblique hole 12;

[0047] It also includes a support layer 6 and a second groove 7. The upper end of the support layer 6 is provided with a second groove 7, and the piston cylinder 8 at the lower end of the nonwoven bag 1 is used to insert into the interior of the second groove 7.

[0048] The diameter of the spring is smaller than the inner diameter of the nonwoven bag 1;

[0049] One end of the limiting ring 3 is used to stretch the non-woven bag 1 to deform;

[0050] according to Figure 2 As shown, in order to increase the air storage capacity, support bars 9 are installed at the upper and lower ends of the non-woven bag 1. The inner wall of the piston chamber 10 is connected to the support bars 9, so that the support bars 9 and the non-woven bag 1 form a piston chamber 10. This allows a large amount of air generated after the non-woven bag 1 is compressed to flow into the piston chamber 10. Then, when a large amount of air fills the piston chamber 10, the air is guided to the first inclined hole 11 and the second inclined hole 12 through the support bars 9, so that the first inclined hole 11 and the second inclined hole 12 can quickly spray air to agitate the inside of the bed core.

[0051] It should be noted that the first inclined hole 11 and the second inclined hole 12 have opposite spray directions, and the angle between the axes of the first inclined hole 11 and the second inclined hole 12 is fan-shaped, thereby increasing the spray range and allowing the air sprayed from the first inclined hole 11 and the second inclined hole 12 to carry away the moisture inside the bed core.

[0052] The breathable layer 4 is made of latex, and several first ventilation holes are provided on the breathable layer 4, with the first ventilation holes penetrating the breathable layer 4.

[0053] The support layer 6 is made of cotton and linen, and a second vent is provided on the support layer 6, which penetrates through the support layer 6.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
