Description

Technical Field

[0001] This utility model relates to the field of mattress technology, and in particular to a glue-free fixing structure for mattress heating elements. 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. With the development of technology, in order to provide people with a more comfortable sleep environment, heating elements are usually set in mattresses to give them a heating function, bringing users a good sleep experience.

[0003] A search revealed a patent document with publication number "CN220423583U" that discloses a mattress comprising a mattress back layer, a mattress surface layer, a 3D air layer, a self-regulating heating fabric, and a sponge layer. The 3D air layer is bonded to the surface of the mattress back layer facing the mattress surface layer via a hot melt adhesive film. The sponge layer is bonded to the surface of the mattress surface layer facing the mattress back layer via a hot melt adhesive film. The self-regulating heating fabric is bonded between the 3D air layer and the sponge layer via a hot melt adhesive film. The self-regulating heating fabric includes a self-regulating heating wire with a linear resistance of 4.0*10²-2.0*10³ Ω*m measured at 10°C. The self-regulating heating wire is composed of a T3001K carbon fiber core and a self-regulating heating outer layer composited around the T3001K carbon fiber core. The rated heating voltage of the self-regulating heating fabric is controlled at 12-36VDC.

[0004] Based on the above search and combined with existing technology, it was found that existing mattress heating elements (such as self-regulating heating cloth in the prior art) are mostly bonded and fixed to other layers of the mattress with adhesives (such as hot melt adhesive film). The use of adhesives makes it easy for the mattress to release substances that are harmful to the human body when heated, which is not conducive to ensuring healthy sleep. Therefore, there is a need for a mattress heating element without adhesive fixing structure. Utility Model Content

[0005] The purpose of this application is to provide a glue-free fixing structure for mattress heating elements to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a glue-free fixing structure for a mattress heating element, comprising:

[0007] The heating element is located between the upper and lower mattress layers.

[0008] The concave-convex body is a curved sheet that is convex on one side and concave on the other side and is integrally formed with the heating element.

[0009] A limiting groove is formed on the surface of one of the mattress layers, and the limiting groove is engaged with the protruding side of the concave-convex body.

[0010] The limiting protrusion is integrally formed on the surface of another mattress layer, and the limiting protrusion is engaged and matched with the recessed side of the concave-convex body.

[0011] Among them, there are multiple concave and convex bodies, limiting grooves, and limiting protrusions, and each corresponds to one another. Multiple concave and convex bodies are evenly distributed on the heating body.

[0012] As a further improvement to this solution, the upper surface of the heating element is integrally formed with upper limit ribs. Multiple upper limit ribs are provided and are located between multiple rows of concave and convex bodies. The upper limit ribs extend laterally and are embedded in the mattress layer that is in contact with the upper surface of the heating element.

[0013] As a further improvement to this solution, the lower surface of the heating element is integrally formed with a lower limiting rib. Multiple lower limiting ribs are provided and are respectively located between multiple rows of concave and convex bodies. The lower limiting ribs extend longitudinally and are embedded in the mattress layer that is attached to the lower surface of the heating element.

[0014] As a further improvement to this solution, the heating element is integrally formed with an extended limiting edge, which extends to the upper and lower ends of the heating element and is respectively arranged around the lower and upper ends of the upper and lower mattress layers.

[0015] As a further improvement to this solution, limiting notches are provided on the periphery of both the upper and lower mattress layers, and the extended limiting edge is embedded in the limiting notch. The outer walls of the extended limiting edge and the outer walls of the mattress layer are all located in the same vertical plane.

[0016] As a further improvement to this solution, the lower end of the concave-convex body is formed with a constricted portion smaller than the maximum inner diameter of the concave-convex body, and the end of the limiting protrusion that intersects with the mattress layer forms an inward concave annular groove that matches the constricted portion.

[0017] In summary, the technical effects and advantages of this utility model are as follows:

[0018] 1. In this utility model, the heating element is connected to the upper and lower mattress layers by multiple concave and convex bodies, multiple limiting grooves, and multiple limiting protrusions, thereby achieving the purpose of glue-free fixing of the heating element. This ensures that the heating element remains stable after installation. At the same time, the glue-free fixing method avoids the disadvantage of easily releasing harmful substances when using glue, thus providing users with a healthy and comfortable sleep environment.

[0019] 2. In this utility model, by setting the upper limit rib and the lower limit rib, the heating body can be limited in the longitudinal and lateral directions, thereby limiting the longitudinal and lateral displacement or deformation of the non-concave and convex parts of the heating body, making the connection between the heating body and the upper and lower mattress layers more stable and improving the stability of the heating body after fixing.

[0020] 3. In this utility model, by setting the extended limiting edge, a structure that connects and limits the upper and lower mattress layers can be formed on the outermost side of the heating body, and a corresponding limiting notch is set so that the outer walls of the extended limiting edge and the outer walls of the mattress layers are all located in the same vertical plane, ensuring the overall shape of the mattress is regular, while improving the connection tightness between the heating body and the mattress layers, and avoiding deformation of the peripheral edges after the heating body is fixed.

[0027] 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.

[0028] Example: Reference Figures 1-4 The mattress heating element shown is a glue-free fixing structure, including a heating element 1, a concave-convex body 2, a limiting groove 5, and a limiting protrusion 6;

[0029] The heating element 1 is located between the upper and lower mattress layers 8 (mattress layers 8 refer to conventional mattress layers such as sponge layers or latex layers in the prior art);

[0030] The concave-convex body 2 is a curved sheet body that protrudes on one side and is recessed on the other side and is integrally formed with the heating body 1. The concave-convex body 2 is a non-heating body.

[0031] The limiting groove 5 is formed on the surface of one of the mattress layers 8, and the limiting groove 5 is engaged and matched with the protruding side of the concave-convex body 2.

[0032] The limiting protrusion 6 is integrally formed on the surface of another mattress layer 8, and the limiting protrusion 6 is engaged and matched with the recessed side of the concave-convex body 2.

[0033] Among them, there are multiple concave and convex bodies 2, limiting grooves 5, and limiting protrusions 6, and each corresponds to one another. Multiple concave and convex bodies 2 are evenly distributed on the heating body 1.

[0034] Based on the above structure, through the combined use of multiple concave and convex bodies 2, multiple limiting grooves 5, and multiple limiting protrusions 6, the heating element 1 and the upper and lower mattress layers 8 form a limiting connection relationship at multiple points, thereby achieving the purpose of fixing the heating element 1 without glue. This ensures that the heating element 1 remains stable after installation. At the same time, the glue-free installation method avoids the drawbacks of easily releasing harmful substances when using glue, bringing a healthy and comfortable sleep environment to the user.

[0035] Furthermore, the upper surface of the heating element 1 is integrally formed with an upper limit rib 3. Multiple upper limit ribs 3 are provided and are respectively located between multiple rows of concave and convex bodies 2. The upper limit ribs 3 extend laterally and are embedded in the mattress layer 8 that is in contact with the upper surface of the heating element 1.

[0036] The lower surface of the heating element 1 is integrally formed with a lower limiting rib 4. Multiple lower limiting ribs 4 are provided and are respectively located between multiple rows of concave and convex bodies 2. The lower limiting ribs 4 extend longitudinally and are embedded in the mattress layer 8 that is attached to the lower surface of the heating element 1.

[0037] By setting the upper limit rib 3 and the lower limit rib 4, the heating body 1 can be limited in the longitudinal and lateral directions, thereby restricting the longitudinal and lateral displacement or deformation of the heating body 1 in the non-concave-convex body 2 part, making the connection between the heating body 1 and the upper and lower mattress layers 8 more stable and improving the stability of the heating body 1 after fixing.

[0038] Furthermore, the heating element 1 has an integrally formed extended limiting edge 7 around its periphery. The extended limiting edge 7 extends to the upper and lower ends of the heating element 1, and the extended limiting edge 7 is respectively arranged around the lower and upper ends of the upper and lower mattress layers 8.

[0039] Both the upper and lower mattress layers 8 have limiting notches 9 around their sides, and the extended limiting edge 7 is embedded in the limiting notch 9. The outer walls of the extended limiting edge 7 and the outer walls of the mattress layer 8 are all located in the same vertical plane.

[0040] By extending the limiting edge 7, a structure that connects and limits the upper and lower mattress layers 8 can be formed on the outermost side of the heating body 1. A corresponding limiting notch 9 is set so that the outer walls of the extended limiting edge 7 and the outer walls of the mattress layers 8 are all located in the same vertical plane, ensuring the overall shape of the mattress is regular. At the same time, the connection between the heating body 1 and the mattress layers 8 is improved, and the deformation of the peripheral edges after the heating body 1 is fixed is avoided.

[0041] Furthermore, the lower end of the concave-convex body 2 has a constricted portion 201 that is smaller than the maximum inner diameter of the concave-convex body 2, and the end of the limiting protrusion 6 that intersects with the mattress layer 8 forms an inward concave annular groove that matches the constricted portion 201, so that the mattress layer 8 and the concave-convex body 2 form a vertical fixed relationship, and prevent the heating element 1 from vertically separating from the mattress layer 8.

[0042] The working principle of this utility model is as follows: In daily use, firstly, the mattress layer 8 with the limiting protrusion 6 is placed at the bottom, then the heating element 1 is placed on top of the mattress layer 8, and then the mattress layer 8 with the limiting groove 5 is placed on top of the heating element 1. After pressing the three together, the limiting protrusion 6 and the limiting groove 5 are engaged and matched with the concave and convex bodies 2. At the same time, the extended limiting edges 7 protruding from the upper and lower sides of the heating element 1 are respectively fitted into the limiting notches 9 of the two mattress layers 8, thereby completing the fixed connection between the heating element 1 and the two mattress layers 8. After the fixed connection, the upper limiting rib 3 and the lower limiting rib 4 are respectively embedded in the two mattress layers 8. The upper limiting rib 3 and the lower limiting rib 4 form longitudinal and lateral limiting for the heating element 1, thereby limiting the longitudinal and lateral displacement or deformation of the heating element 1 in the non-concave and convex body 2 part, making the connection between the heating element 1 and the upper and lower mattress layers 8 more stable and improving the stability of the heating element 1 after fixing.

[0043] 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.
