[0023] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0025] The following is combined with Figure 1-2 The technical solution of the utility model is further explained through specific implementation methods.

[0026] Reference Figure 1 , discloses an airbag spring mattress, including an airbag assembly, an outer cover 2, an inner core 3 and an inflation device (not shown in the figure), wherein the outer cover 2 is arranged on the outside of the inner core 3, the airbag assembly is buried in the inner core 3, the airbag assembly is connected to the inflation device, the inflation device provides inflation and deflation control for the airbag assembly, and plays a major supporting role under the mutual cooperation of the inner core 3 and the airbag assembly, and the outer cover 2 is in direct contact with the human body, playing the role of providing a soft touch to the human body.

[0027] Reference Figure 1 and Figure 2 The airbag assembly may be damaged during long-term use, and currently most airbag assemblies are troublesome to replace. Based on this, in order to facilitate the replacement of the airbag assembly, in this embodiment, the mattress also includes a gas processing unit 4 that is detachably provided with the airbag assembly.

[0028] Among them, in this embodiment, the airbag assembly includes multiple airbag springs 1. Compared with ordinary airbag components, the airbag spring 1 has a spring structure. On the basis of gas support, it can also provide an additional spring support effect, which can provide greater support force and more prominent support effect.

[0029] In addition, the airbag spring 1 is preferably made of a material with good elasticity, such as rubber, elastic fiber or latex. Here, by using an elastic material as the material of the airbag spring 1, due to the different hardnesses of different materials, the support feel of the mattress can be adjusted according to the needs of the user, and an elastic structure with different tension, resilience and support levels can be formed, thereby meeting more support needs. In this embodiment, there is no specific restriction on the material of the airbag spring 1, and any material that can achieve elastic support can be tried and should be included in the protection scope.

[0030] Furthermore, in order to realize the separate disassembly and assembly of the airbag spring 1, in this embodiment, the gas processing unit 4 is a layered structure, which can be made of an elastic material, such as rubber. The gas processing unit 4 has a cavity for gas exchange inside, and the cavity is defined as an air flow channel 41; furthermore, an air inlet and an air outlet are provided through one side of the gas processing unit, and the inflation device is selected as an air pump element in this embodiment. The inflation device is fixedly connected to the gas processing unit 4 through a pipeline, and is respectively connected to the air inlet and the air outlet.

[0031] At this time, start the inflation device, which can blow air into the gas processing unit 4 through the air inlet, and then distribute the air pressure to each airbag spring 1 through the gas processing unit 4. In addition, the air pump element can also extract the gas in the gas processing unit 4 from the air outlet. At this time, the air flow channel 41 forms a negative pressure and distributes it to multiple airbag springs 1 at the same time, so that the support degree of the airbag spring 1 is reduced, achieving the effect of uniformly regulating the support of the airbag spring 1, so as to avoid the situation where the support degree of different airbag springs 1 is not uniform.

[0032] In addition, refer to Figure 2, a plurality of airbag interfaces 42 connected to the air flow channel 41 are arranged on the top of the gas processing unit 4. Specifically, the airbag interface 42 is a columnar structure in this embodiment, and the column has ventilation holes running through both ends. One end of the airbag interface 42 is fixedly connected to the gas processing unit 4, and the ventilation holes are connected to the air flow channel 41. The other end of the airbag interface 42 protrudes to the outside of the gas processing unit 4. At the same time, a connection hole for plugging and installing the airbag interface 42 is arranged through the bottom of the airbag spring 1. The connection hole and the airbag interface 42 can be fixed by interference fit. At this time, the airbag spring 1 can be installed by placing the airbag spring 1 on the top of the gas processing unit 4 and inserting the airbag interface 42 into the connection hole. If the airbag spring 1 needs to be disassembled, the airbag spring 1 can be directly pulled upward from the gas processing unit 4. The disassembly and assembly process is convenient and efficient.

[0033] It should be noted that, in the specific setting, the number of airbag springs 1 can be twenty, fifty or one hundred, and multiple airbag springs 1 are distributed in an array arrangement inside the inner core 3, playing the role of multi-region support, and the supporting force is more balanced, and the specific setting number of airbag springs 1 can be set according to actual needs. The specific setting number of airbag springs 1 is not restricted here. Accordingly, the setting number and arrangement of airbag interfaces 42 are compatible with the gas processing unit 4, and multiple airbag interfaces 42 are also arranged in an array on the gas processing unit 4, which will not be repeated here.

[0034] Continue to refer to Figure 1 and Figure 2 When the airbag assembly is arranged in the inner core 3, the conventional inner core 3 structure is usually fixed by glue, which makes it difficult to disassemble the airbag assembly. Here, the inner core 3 in this embodiment is detachable. Specifically, the inner core 3 includes an upper comfort layer 31 and a lower comfort layer 32. The gas processing unit 4 is directly stacked on the lower comfort layer 32. The lower comfort layer 32 can be composed of a cotton layer structure, which will not be described in detail here; at the same time, the airbag assembly is stacked between the upper comfort layer 31 and the lower comfort layer 32. The tops of multiple airbag springs 1 are in contact with the upper comfort layer 31 and are evenly arranged between the upper comfort layer 31 and the lower comfort layer 32 to provide partition support for the upper comfort layer 31.

[0035] Furthermore, the airbag assembly is mainly taken in and placed from the top during disassembly, so the upper comfort layer 31 includes a first cotton layer 311, a second cotton layer 312 and a third cotton layer 313 stacked in sequence from top to bottom. By taking out the first cotton layer 311, the second cotton layer 312 and the third cotton layer 313 from the top of the airbag assembly, the airbag spring 1 can be directly disassembled and assembled, and the process is convenient and quick.

[0036] Furthermore, look back Figure 1In this embodiment, the jacket 2 also adopts a detachable structure. Specifically, the jacket 2 includes an upper fabric layer 21 and a lower fabric layer 22 that are detachable from each other. A zipper 9, a Velcro or a button structure may be provided between the upper fabric layer 21 and the lower fabric layer 22. By adopting the above connection method, the two can be detached from each other, which is convenient for use. In this embodiment, the upper fabric layer 21 and the lower fabric layer 22 are detachably connected by adding a zipper 9. By disassembling the upper fabric layer 21, the first cotton layer 311, the second cotton layer 312 and the third cotton layer 313 can be directly taken out, so as to facilitate the subsequent disassembly and assembly of the airbag spring 1.

[0037] Continue to refer to Figure 1 and Figure 2 In order to improve the support stability of the periphery of the mattress body, the inner core 3 also includes a high-elastic sponge layer 8, which is arranged between the upper comfort layer 31 and the lower comfort layer 32, and is respectively in contact with the upper comfort layer 31 and the lower comfort layer 32. The high-elastic sponge layer 8 is arranged around the circumference of the airbag assembly and is arranged on the outside of the airbag assembly; at this time, the high-elastic sponge layer 8 can not only support the periphery of the mattress body, but also provide lateral support for the airbag assembly, and the support stability of the periphery of the mattress body is improved.

[0038] In the specific configuration, the high-elastic sponge layer 8 includes a plurality of high-elastic sponge strips. In the present embodiment, the number of the high-elastic sponge strips is four. The four high-elastic sponge strips are distributed around the airbag assembly and are sequentially connected end to end to form a closed-loop support structure. The closed-loop structure can provide all-round support for the mattress, and the structural stability of the mattress is improved. It should be noted that the high-elastic sponge layer 8 may also adopt a 3D cotton structure in another embodiment. Any sponge structure that can provide high-elastic support may be tried, and no specific limitation is made here.

[0039] Continue to refer to Figure 1 and Figure 2 In actual use, mattresses need to be frequently inflated and deflated, and the inflation and deflation actions usually produce certain noises, which may affect the user experience.

[0040] In order to reduce the noise generated by the mattress during use, on the one hand, a first sound-insulating cotton layer 5 is laid between the third cotton layer 313 and the airbag assembly, and the first sound-insulating cotton layer 5 can reduce the noise transmitted upward to the user's position, and can directly reduce the noise heard by the user.

[0041] Secondly, in this embodiment, a second sound insulation cotton layer 6 is provided at the inner edge of the high elastic sponge layer 8. The second sound insulation cotton layer 6 can be provided at the inner edge of the high elastic sponge layer 8 by adhesive bonding. At this time, the second sound insulation cotton layer 6 can isolate the path of noise transmitted from the side of the mattress to the outside, and the noise reduction effect is further optimized.

[0042] On the third aspect, the gaps between the high-elastic sponge strips may also become a noise escape path. Based on this, a third sound insulation cotton layer 7 is filled between two adjacent high-elastic sponge strips. The third sound insulation cotton layer 7 supplements and blocks the noise escape path, and the noise reduction effect is further improved.

[0043] Reference Figure 1 In order to improve the comfort of the user when sitting or lying, the hardness of the first cotton layer 311, the second cotton layer 312 and the third cotton layer 313 increases in sequence. In this embodiment, the first cotton layer 311 can be made of a relatively soft material, such as super soft sponge.

[0044] The hardness of the second cotton layer 312 is harder than that of the first cotton layer 311. In this embodiment, an eggshell paper cotton structure is adopted, wherein the surface of the second cotton layer 312 facing the first cotton layer 311 has a wavy pattern, and the wavy pattern can enhance a certain elastic support effect. At the same time, by attaching the wavy pattern to the first cotton layer 311, a plurality of hollow cavities are formed between the two, and the hollow cavities can also have a certain noise reduction effect.

[0045] In addition, the third cotton layer 313 is made of cotton felt, which has a harder texture and can provide firm support for the first cotton layer 311 and the second cotton layer 312 . By adopting a layered structure from soft to hard from top to bottom, the comfort and wrapping feeling of the upper comfort layer 31 can be effectively improved.

[0046] The implementation principle of the embodiment of the present application is: the air channel 41 is inflated or deflated by an inflation device, thereby controlling the synchronous inflation or deflation of multiple airbag springs 1 in the airbag assembly; when the airbag spring 1 is squeezed, excess air will flow into the gas processing unit 4, thereby achieving secondary buffering, and then recovering after the pressure disappears, with a significant supporting effect; and the gas processing unit 4 also has the function of maintaining pressure for a long time, and the gas processing unit 4 and the air channel 41 can provide a constant gas pressure for the airbag spring 1, thereby reducing the noise impact caused by frequent inflation and deflation in conventional technology, and the user experience is optimized and improved.

[0047] When the airbag spring 1 is leaking, the upper fabric layer 21 can be disassembled first, and then the first cotton layer 311, the second cotton layer 312 and the third cotton layer 313 can be taken out respectively. Then, the leaking airbag spring 1 can be directly pulled out and disassembled, and the new airbag spring 1 can be pressed and installed into the gas processing unit 4. The operation is easy to understand and the process is convenient and quick.

[0048] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
