Description

Technical Field

[0001] This application relates to the field of furniture, and in particular to a nested airbag and mattress. Background Technology

[0002] With the development of technology, AI smart mattresses have received widespread attention for their ability to automatically adjust parameters such as firmness and height based on human characteristics and sleep patterns, providing users with a more comfortable sleep experience. Airbags, as an important component, play a key role in realizing these functions.

[0003] Currently, existing AI smart mattresses have some issues with their airbags during use. When an airbag leaks, the entire mattress usually needs to be sent back to the factory for repair and replacement. This approach is costly and time-consuming, forcing users to temporarily stop using the mattress during the repair process, causing significant inconvenience to their daily lives and ultimately reducing their satisfaction and trust in the mattress. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a nested airbag that can reduce mattress maintenance costs and improve the user experience.

[0005] The nested airbag according to an embodiment of this application includes: an outer airbag; an inner airbag nested inside the outer airbag; and an air supply assembly for supplying air to the interior of the outer airbag or the interior of the inner airbag. When the air supply assembly supplies air to the interior of the outer airbag, the inner airbag is in a contracted state; when the air supply assembly supplies air to the interior of the inner airbag, the inner airbag is in an inflated state.

[0006] According to one embodiment of this application, when the inner airbag is in a contracted state, the volume of the inner airbag is no more than 5% of the volume of the outer airbag when it is normally fully inflated.

[0007] According to one embodiment of this application, when the inner airbag is inflated, the volume of the inflated inner airbag is 95% to 100% of that of the outer airbag when it is normally fully inflated.

[0008] According to one embodiment of this application, the air supply assembly includes a first air intake channel and a second air intake channel. The first air intake channel is used to introduce gas into the interior of the outer airbag, and the second air intake channel is used to introduce gas into the interior of the inner airbag.

[0009] According to one embodiment of this application, the air supply assembly includes a first air tube and a second air tube. The inner cavity of the first air tube defines a first air intake channel and is connected to an outer airbag. The inner cavity of the second air tube defines a second air intake channel and is connected to an inner airbag.

[0010] According to one embodiment of this application, a sealing element is included; a second air tube passes through the outer air bladder and leads to the inner air bladder, the sealing element is disposed on the periphery of the second air tube, and the inner air bladder is sealed to the outer air bladder through the sealing element.

[0011] According to one embodiment of this application, a first valve is provided on a first air tube for controlling the opening and closing of the first air tube, and a second valve is provided on a second air tube for controlling the opening and closing of the second air tube. The first valve and the second valve work independently of each other.

[0012] The mattress according to another embodiment of this application includes the aforementioned nested airbags.

[0013] According to another embodiment of the present application, the mattress includes a control box, and the first and second air pipes of the air supply assembly are detachably connected to the control box. The control box is used to control the gas to flow along the air supply assembly to the interior of the outer air bladder or the interior of the inner air bladder.

[0014] According to another embodiment of the mattress of this application, there are multiple nested airbags, and the first or second air tube of each nested airbag is detachably connected to the control box, which can simultaneously control the air supply of multiple nested airbags.

[0015] The nested airbag according to the embodiments of this application has at least the following beneficial effects: Under normal working conditions, when air is supplied from the outside to the inside of the outer airbag through the air supply component, the inner airbag is in a contracted state; when the outer airbag leaks, the air supply component supplies air from the outside to the inside of the inner airbag, causing the inner airbag to expand and fill the space where the outer airbag was before the leak. This not only improves the service life of the airbag but also reduces the maintenance cost of the airbag. The airbag can be self-repaired simply by inflating the inner airbag, eliminating the need for return to the factory for repair and improving the user experience.

[0016] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] The following is for reference. Figures 1 to 4 This application describes a nested airbag and mattress according to embodiments thereof.

[0033] See Figure 1 One embodiment of the nested airbag 1000 includes an outer airbag 100, an inner airbag 200, and an air supply assembly 300. The inner airbag 200 is nested inside the outer airbag 100. The air supply assembly 300 is used to supply air to the interior of the outer airbag 100 and the interior of the inner airbag 200. When the air supply assembly 300 supplies air to the interior of the outer airbag 100, the inner airbag 200 is in a contracted state; when the air supply assembly 300 supplies air to the interior of the inner airbag 200, the inner airbag 200 is in an inflated state.

[0034] like Figure 1 As shown, the nested airbag 1000 includes an outer airbag 100, within which is nested an inner airbag 200. The inner airbag 200 is nested inside the outer airbag 100. An air supply assembly 300 is connected to both the inner and outer airbags 100, supplying air to both the inner and outer airbags. In normal operation, the air supply assembly 300 introduces gas into the outer airbag 100, eliminating the need to supply gas to the inner airbag 200. At this time, the outer airbag 100 inflates, while the inner airbag 200 remains in a contracted state. Figure 3 As shown, during use, when an air leak 500 appears on the surface of the external airbag 100, such as... Figure 3As shown, when the outer airbag 100 leaks and contracts, the air supply component 300 introduces gas into the inner airbag 200, causing the contracted inner airbag 200 to inflate and remain in an inflated state, thus supporting the outer airbag 100. This keeps the nested airbag 100 fully inflated and maintains its normal volume. This design improves the lifespan of the airbags and reduces maintenance costs. Simply inflating the inner airbag 200 allows for self-repair, enabling continued use without the need for factory repairs, thus enhancing the user experience. It is understandable that the number of inner airbags 200 in the nested airbag 1000 can be one or more. For example, when there are two inner airbags 200, after the outer airbag 100 leaks, one of the two inner airbags 200 is inflated and put into an expanded state, so that the nested airbag 1000 can be used again. If the inner airbag 200 also leaks during use, then the other inner airbag 200 is inflated and put into a expanded state, so that the nested airbag 1000 can be used again.

[0035] Furthermore, when the inner airbag 200 is in a contracted state, its volume is no more than 5% of the volume of the outer airbag 100 when it is normally fully inflated; when the inner airbag 200 is in an inflated state, its volume after inflation is 95% to 100% of the volume of the outer airbag 100 when it is normally fully inflated. In other words, the inner airbag 200 is nested inside the outer airbag 100. When the inner airbag 200 is not inflated while the outer airbag 100 is inflated, the volume occupied by the inner airbag 200 inside the outer airbag 100 is no more than 5% of the volume of the outer airbag 100 when it is fully inflated. This prevents the inner airbag 200 from occupying too much space in the outer airbag 100, which would result in insufficient air storage in the outer airbag 100 and hinder its normal use, thus ensuring the user experience. When the outer airbag 100 leaks air, the inner airbag 200 inflates and expands to its inflated state. In this state, the volume of the inner airbag 200 is 95% to 100% of the volume of the outer airbag 100 when it is fully inflated. This ensures that the inflated inner airbag 200 can fill the expansion space of the outer airbag 100 when it is inflated, keeping the nested airbag as consistent as possible with the previous state and avoiding affecting the user experience.

[0036] In some embodiments of this application, such as Figure 1As shown, the air supply assembly 300 includes a first air intake channel and a second air intake channel. The first air intake channel is used to introduce gas into the interior of the outer airbag 100, and the second air intake channel is used to introduce gas into the interior of the inner airbag 200. In other words, the air supply assembly 300 includes a first air intake channel leading to the interior of the outer airbag 100. In the normal operating state of the nested airbag 1000, the air supply assembly 300 introduces gas into the interior of the outer airbag 100 through the first air intake channel, and the outer airbag 100 inflates for normal use by the user. The air supply assembly 300 also includes a second air intake channel leading to the interior of the inner airbag 200. Figure 3 As shown, when a leak 500 appears on the surface of the outer airbag 100 of the nested airbag 1000, the outer airbag 100 leaks and contracts. The air supply component 300 introduces gas into the interior of the inner airbag 200 through the second air intake channel, causing the inner airbag 200 to inflate and expand, thereby supporting the outer airbag 100. This keeps the nested airbag 1000 full and maintains its normal volume, making it convenient for users to use normally.

[0037] Furthermore, the air supply assembly 300 includes a first air tube 310 and a second air tube 320. The inner cavity of the first air tube 310 defines a first air intake channel, and the first air tube 310 is connected to the outer airbag 100. The inner cavity of the second air tube 320 defines a second air intake channel, and the second air tube 320 is connected to the inner airbag 200. That is, the air supply assembly 300 includes a first air tube 310 leading to the interior of the outer airbag 100. The inner cavity of the first air tube 310 defines the first air intake channel. In the normal operating state of the nested airbag 1000, the air supply assembly 300 introduces gas into the interior of the outer airbag 100 through the first air tube 310, and the outer airbag 100 inflates for normal use by the user. The air supply assembly 300 includes a second air tube 320 leading to the interior of the inner airbag 200, and the inner cavity of the second air tube 320 defines the second air intake channel. When a leak 500 appears on the surface of the outer airbag 100 of the nested airbag 1000, the outer airbag 100 leaks and contracts. The air supply component 300 introduces gas into the interior of the inner airbag 200 through the second air tube 320, causing the inner airbag 200 to inflate and expand, thereby supporting the outer airbag 100. This keeps the nested airbag 1000 full and maintains its normal volume, making it convenient for users to use normally.

[0038] Furthermore, such as Figure 2As shown, the nested airbag 1000 also includes a sealing element 400; the second air tube 320 passes through the outer airbag 100 and leads to the inner airbag 200, and the sealing element 400 is disposed around the second air tube 320. The inner airbag 200 is sealed to the outer airbag 100 through the sealing element 400. That is, the second air tube 320 can only lead to the inner airbag 200 by passing through the outer airbag 100. In order to prevent the gas of the outer airbag 100 from leaking out from the passage of the second air tube 320, a sealing element 400 is provided around the second air tube 320. Specifically, the sealing element 400 can be formed into a sealing ring with good elasticity. The sealing ring is fitted onto the second air tube 320, with one side of the sealing ring welded to the inner airbag 200 and the other side welded to the outer airbag 100, so that the inner airbag 200 and the outer airbag 100 are connected together at the passage of the second air tube 320, thereby ensuring the airtightness of the passage of the second air tube 320. It is understandable that the sealing element 400 can connect the inner airbag 200 and the outer airbag 100 through connection methods other than welding, such as strong adhesive connection, hot melt adhesive connection, etc., as long as the airtightness of the second air tube 320 passing through is guaranteed.

[0039] Furthermore, such as Figure 1 As shown, a first valve 311 is provided on the first air tube 310, which is used to control the opening and closing of the first air tube 310. A second valve 321 is provided on the second air tube 320, which is used to control the opening and closing of the second air tube 320. The first valve 311 and the second valve 321 work independently of each other. That is to say, the user can control the opening and closing of the first valve 311 to introduce gas into the outer airbag 100, and control the opening and closing of the second valve 321 to introduce gas into the inner airbag 200.

[0040] Please see Figure 4In another embodiment of this application, the mattress 2000 includes the nested airbags 1000 as described above, and a control box 600. The control box 600 controls the flow of gas along the air supply assembly 300 to the outer airbag 100 and the inner airbag 200. The first air tube 310 and the second air tube 320 of the air supply assembly 300 are both connected to the control box 600. When the outer airbag 100 leaks gas, the control box 600 controls the second valve 321 of the second air tube 320 to open. That is, the mattress 2000 contains the control box 600 and the nested airbags 1000 described above. The control box 600 is connected to the first air tube 310 and the second air tube 320. The first valve 311 and the second valve 321 are located inside the control box 600. The control box 600 can control the first valve 311 and the second valve 321 to respectively supply gas to the outer airbag 100 and the inner airbag 200. When the mattress 2000 is in normal use, the outer airbag 100 of the nested airbag 1000 is inflated, while the inner airbag 200 is not vented with air. When the outer airbag 100 leaks air, the mattress 2000 cannot be used normally. The control box 600 can control the second air tube 320 to vent air into the inner airbag 200, causing the inner airbag 200 to inflate. The inflated inner airbag 200 supports the leaking outer airbag 100, keeping the nested airbag 1000 inflated, thus allowing the nested airbag 1000 to support the mattress 2000 again for normal use by the user.

[0041] Furthermore, both the first air pipe 310 and the second air pipe 320 of the air supply component 300 are detachably connected to the control box 600. When the outer airbag 100 is not leaking gas, the first air pipe 310 is connected to the control box 600, and the second air pipe 320 is disconnected from the control box 600. When the outer airbag 100 leaks gas, the first air pipe 310 is disconnected from the control box 600, and the second air pipe 320 is connected to the control box 600. That is, when the outer airbag 100 is in normal use, the first air pipe 310 is connected to the control box 600, and the second air pipe 320 is not connected to the control box 600. When the outer airbag 100 leaks gas, simply disconnect the first air pipe 310 from the control box 600 and then reconnect the second air pipe 320 to the control box 600. The control box 600 can then control the second valve 321 to open and inflate the inner airbag 200, allowing the mattress 2000 to return to normal use.

[0042] In some embodiments of this application, such as Figure 4As shown, there are multiple nested airbags 1000. The first air tube 310 and / or the second air tube 320 of each nested airbag 1000 are detachably connected to the control box 600. The control box 600 can simultaneously control the air supply to multiple nested airbags 1000. Furthermore, the multiple nested airbags 1000 are arranged in a rectangular array within the mattress 2000, which helps to distribute the nested airbags 1000 in various positions within the mattress 2000. Users can adjust the inflation volume of each nested airbag 1000 using the controller to adapt to the user's lying posture and improve the user experience.

[0043] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
