Description

Technical Field

[0001] The utility model relates to daily necessities, in particular to a deformation-proof airbag and an inflatable mattress. Background Art

[0002] During sleep, the role of the mattress cannot be underestimated as it is directly related to our rest quality. With the continuous innovation of technology, the manufacturing process of mattresses has also been continuously improved. Especially the inflatable airbag mattress has won the favor of many consumers due to its excellent comfort and support. The working principle of this kind of mattress is to adjust the hardness by regulating inflation and deflation to meet various sleep preferences.

[0003] To further improve the sleeping feeling, the inflatable mattress usually designs multiple independent airbags, so as to provide personalized air pressure support for the sleeping area. In an ideal state, each airbag should be a regular cuboid, so that the contact surfaces between the airbags are seamlessly butted. However, as Figure 1 shown, when the existing airbag 100 is inflated, it will expand and deform outward, and each surface will present an arc protruding in the middle, resulting in a support gap 200 between the tops of adjacent airbags. If a user lies in this gap, the comfort will be reduced.

[0004] In view of this, it is necessary to optimize the existing inflatable airbag design to narrow the support gap between adjacent airbags, thereby improving the comfort during sleep.

[0005] The above information disclosed in this background section is only included to enhance the understanding of the background of the present disclosure, and thus may include information that does not form the prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0006] An object of the utility model is to provide a deformation-proof airbag and an inflatable mattress, which can effectively inhibit the arc deformation of the airbag, thereby narrowing the support gap between adjacent airbags and improving the comfort during sleep.

[0007] To achieve the above object, on the one hand, the utility model provides a deformation-proof airbag, including:

[0008] An airbag body, which encloses to form an airbag inner cavity;

[0009] An elastic support module, which is located in the airbag inner cavity, and the outer surface of the elastic support module is fixedly attached to the inner wall of the airbag body to limit the arc deformation generated after the airbag body is inflated.

[0010] Optionally, the elastic support module includes a module outer sleeve whose outer surface is fixedly attached to the inner wall of the airbag body, and a plurality of elastic columns located inside the module outer sleeve.

[0011] Optionally, the module outer cover and the airbag body are fixed by pasting or hot pressing.

[0012] Optionally, the module outer cover is made of non-woven fabric.

[0013] Optionally, the elastic column is a spring cylinder, a silica gel column or a rubber column.

[0014] Optionally, the airbag body is in a cuboid shape, and the longitudinal edge positions of the airbag body are rounded corner structures adapted to the elastic columns.

[0015] Optionally, it further includes:

[0016] An inflation joint, which is installed on the airbag body and passes through the module outer cover, and is used to connect the internal space of the module outer cover to the external space of the anti-deformation airbag.

[0017] Optionally, it further includes:

[0018] A pressure sensor, which is located inside the module outer cover and is used to detect the internal air pressure of the airbag body.

[0019] On the other hand, an inflatable mattress is provided, which includes a mattress outer cover and a plurality of the anti-deformation airbags located inside the mattress outer cover.

[0020] Optionally, a plurality of adjacent anti-deformation airbags enclose an airbag gap, and a filling airbag is provided at the airbag gap.

[0021] The beneficial effects of the present utility model are as follows: An anti-deformation airbag and an inflatable mattress are provided. When gas is filled into the airbag cavity to make the airbag body gradually expand, since the outer surface of the elastic support module is fixedly attached to the inner wall of the airbag body, therefore, the elastic support module will tighten each wall surface of the airbag cavity, restricting each surface of the airbag body from arching outwards, and greatly reducing the degree of outward expansion deformation of the airbag body. After the degree of outward expansion deformation decreases, the support gap between the top surfaces of two adjacent anti-deformation airbags will also be greatly reduced.

[0022] Therefore, the anti-deformation airbag provided by the present utility model can effectively inhibit the arc-shaped expansion deformation of the airbag, thereby reducing the support gap between adjacent airbags and improving the comfort during sleep. Description of the Drawings

[0040] The present utility model provides an anti-deformation airbag and an inflatable and deflatable mattress with the anti-deformation airbag, which are applicable to the application scenario of providing sleep support for the human body, and can effectively inhibit the arc-shaped expansion deformation of the airbag, thereby reducing the support gap between adjacent airbags and improving the comfort during sleep.

[0041] See Figure 2 , the inflatable mattress provided in this embodiment includes a mattress outer cover 300 and a plurality of anti-deformation airbags 400 located inside the mattress outer cover 300.

[0042] Among them, see Figure 3 , the anti-deformation airbag 400 includes an airbag body 1 and an elastic support module 2. The airbag body 1 surrounds to form an airbag inner cavity; the elastic support module 2 is located in the airbag inner cavity, and the outer surface of the elastic support module 2 is fixedly attached to the inner wall of the airbag body 1 to limit the arc-shaped deformation generated after the airbag body 1 is inflated.

[0043] For the anti-deformation airbag 400 provided in this embodiment, when the airbag inner cavity is filled with gas and the airbag body 1 gradually expands, since the outer surface of the elastic support module 2 is fixedly attached to the inner wall of the airbag body 1, the elastic support module 2 will tighten each wall surface of the airbag inner cavity, restricting each surface of the airbag body 1 from bulging outwards and greatly reducing the degree of outward expansion deformation of the airbag body 1. After the degree of outward expansion deformation decreases, the support gap between the top surfaces of two adjacent anti-deformation airbags 400 will also be greatly reduced.

[0044] Therefore, the anti-deformation airbag 400 provided by the present utility model can effectively inhibit the arc-shaped expansion deformation of the airbag, thereby reducing the support gap 200 between adjacent airbags and improving the comfort during sleep.

[0045] In this embodiment, see Figure 4 , the elastic support module 2 includes a module outer cover 201 whose outer surface is fixedly attached to the inner wall of the airbag body 1 and a plurality of elastic columns 202 located inside the module outer cover 201.

[0046] Specifically, the top surface of the module outer casing 201 is fixedly attached to the top surface of the inner cavity of the airbag, the bottom surface of the module outer casing 201 is fixedly attached to the bottom surface of the inner cavity of the airbag, and the outer side surface of the module outer casing 201 is fixedly attached to the side wall of the inner cavity of the airbag.

[0047] In this embodiment, the elastic columns 202 have multiple functions, mainly including the following points:

[0048] ① Provide uniform support: The elastic columns 202 play a role similar to that of a skeleton inside the airbag body 1. They can disperse and uniformly transmit the pressure generated during inflation, thereby maintaining the flatness of the surface of the airbag body 1 and reducing deformation caused by excessive local pressure.

[0049] ② Prevent arc-shaped deformation: When the airbag body 1 is inflated, the elastic columns 202 can limit the outward expansion of the inner wall of the airbag body 1 to form an arc, maintaining the regular shape of the airbag body 1, thereby reducing the support gap 200 between adjacent anti-deformation airbags 400 and improving the comfort and uniformity of the entire mattress.

[0050] ③ Enhance structural stability: The elastic columns 202 increase the structural stability of the inside of the airbag body 1, making the airbag body 1 not easily collapse when bearing weight and maintaining good support performance.

[0051] ④ Adjust hardness: By changing the number, arrangement pattern or material of the elastic columns 202, the hardness of the airbag body 1 can be adjusted to meet the sleep preferences of different users.

[0052] ⑤ Improve durability: The elastic columns 202 help reduce wear and tear of the airbag material because they can disperse pressure and impact, thereby extending the service life of the mattress.

[0053] Optionally, the elastic columns 202 are arranged in a matrix, which is beneficial to uniformly disperse the pressure and maintain the stability of the airbag shape. Of course, the arrangement and number of the elastic columns 202 can be optimized according to the size of the airbag body 1 and the expected supporting force, and this embodiment does not make any limitations.

[0054] Optionally, the airbag body 1 is made of highly elastic TPU (thermoplastic polyurethane), and the module outer casing 201 is made of non-woven fabric. The module outer casing 201 and the airbag body 1 are fixed by pasting or hot pressing.

[0055] The non-woven fabric is light and easy to cut into various shapes and sizes according to design requirements, which is beneficial to reducing production costs and processing difficulties. Of course, in some other embodiments, the module outer casing 201 can also be a polyurethane (PU) film with waterproof and moisture-proof functions, or a light and waterproof polyethylene (PE) film, etc., and this embodiment does not make any limitations in this regard.

[0056] Pasting or hot - pressing fixation ensures the tight combination of the module outer sleeve 201 and the inner wall of the airbag, preventing gas leakage. Optionally, when using paste fixation, an environmentally friendly and harmless adhesive is preferably selected to ensure the health of users.

[0057] Optionally, the elastic column 202 is a spring cylinder, a silica gel column or a rubber column. Of course, in some other embodiments, the elastic support module 2 can also be made of lightweight and pressure - resistant materials, such as high - strength plastic or metal mesh, to ensure no deformation during long - term use. This design can also improve the uniformity of support and reduce discomfort during sleep.

[0058] In this embodiment, the airbag body 1 is in a cuboid shape, and the longitudinal edge position of the airbag body 1 is a rounded - corner structure 101 adapted to the elastic column 202. By setting the longitudinal edge position of the airbag body 1 as the rounded - corner structure 101, the rounded - corner structure 101 can be adapted to the circumferential surface of the elastic column 202, increasing the fixing area between the airbag body 1 and the elastic support module 2, thereby improving the reliability of the connection between the airbag body 1 and the elastic support module 2, and also improving the anti - arc deformation performance of the airbag body 1.

[0059] Correspondingly, a plurality of adjacent anti - deformation airbags 400 surround to form an airbag gap, and a filling airbag 500 is provided at the airbag gap. The filling airbag 500 is used to fill the airbag gap, further improving the overall flatness and support of the mattress.

[0060] The anti - deformation airbag 400 further includes an inflation joint and a pressure sensor. The inflation joint is installed on the airbag body 1 and passes through the module outer sleeve 201 for connecting the internal space of the module outer sleeve 201 to the external space of the anti - deformation airbag 400. The pressure sensor is located inside the module outer sleeve 201 for detecting the internal air pressure of the airbag body 1.

[0061] The airbag body 1 can be inflated and deflated through the inflation joint. During the inflation and deflation process, the pressure value detected by the pressure sensor is read at all times. If the preset pressure has been reached, the inflation and deflation operation can be stopped.

[0062] The anti - deformation airbag 400 and the inflatable mattress provided in this embodiment have the following advantages:

[0063] ① An elastic support module 2 that fits and fixes to the inner wall of the airbag body 1 is arranged inside the airbag body 1, effectively suppressing the arc - shaped expansion deformation of the airbag body 1 after inflation and improving the uniform support of the mattress;

[0064] ② The setting of the elastic column 202 provides uniform support force, reduces deformation caused by excessive local pressure, and improves the comfort and durability of the mattress;

[0065] ③ The module jacket 201 made of non-woven fabric material is light and easy to cut, reducing the production cost and processing difficulty;

[0066] ④ The design of the airbag body 1 with the rounded corner structure 101 increases the fixing area between the airbag and the elastic support module 2, improving the reliability of the connection;

[0067] ⑤ The setting of the filling airbag 500 further improves the overall flatness and support of the inflatable mattress.

[0068] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of this application, using the content recorded in the text and drawings of the specification of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of this application.
