Description

Technical Field

[0001] This application relates to the field of mattress technology, and more particularly to a mattress. Background Technology

[0002] A mattress is an essential sleep tool in people's daily lives, an item placed between the human body and the bed to ensure consumers get healthy and comfortable sleep. Current massage mattresses incorporate massage airbags to achieve pneumatic massage and pneumatic support.

[0003] The airbags are inflated and deflated by an air source component, which is usually located in the leg area of ​​the mattress. To facilitate the maintenance of the air source component, the leg area of ​​the mattress usually cannot have airbags, and is only covered with soft materials such as sponge, so that the user's legs cannot receive pneumatic massage and pneumatic support.

[0040] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application.

[0041] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0042] Please see Figures 1 to 3 This application provides a mattress 100, which includes a mattress base 1, a leg airbag assembly 2, and an air source assembly 3.

[0043] The mattress base 1 can be square, for example, rectangular flat. It is understood that the mattress base 1 includes a leg area 1a, a torso area 1b, a head area 1c, and a knee area 1d. When the user lies flat on the mattress 100, the leg area 1a, torso area 1b, head area 1c, and knee area 1d correspond to the user's legs, torso, head, and knees, respectively. The knee area 1d is at least partially located within the leg area 1a.

[0044] The leg airbag assembly 2 is disposed in the leg area 1a. The leg airbag assembly 2 is used to inflate when inflated and to contract when deflated, so that the leg airbag assembly 2 is used to controllably support the user's legs.

[0045] The air source component 3 is located on the mattress base 1 and is in fluid communication with the leg airbag component 2. The air source component 3 is used to inflate and deflate the leg airbag component 2. Please refer to [link / reference]. Figure 4 The air source component 3 includes an air valve assembly 31 and an air pump 32. The air valve assembly 31 controls the opening and closing of the air passage between the air pump 32 and the leg airbag assembly 2, thereby controlling whether the leg airbag assembly 2 is inflated. The air valve assembly 31 also has a vent (not shown), which controls the opening and closing of the air passage between the vent and the leg airbag assembly 2, thereby controlling the deflation of the leg airbag assembly 2. When the air passage between the leg airbag assembly 2 and the air pump 32 and the vent is disconnected, the leg airbag assembly 2 is in a pressure-holding state, which can be either inflated to support the user's legs or contracted. When the air source component 3 repeatedly inflates and deflates the leg airbag assembly 2, the leg airbag assembly 2 repeatedly expands and contracts to massage the user's legs.

[0046] Understandably, the air source component 3 is typically located in the leg area 1a of the mattress 100. To facilitate maintenance of the air source component 3, the leg area 1a of the mattress 100 typically cannot accommodate the leg airbag component 2, being only covered with soft materials such as sponge, thus preventing pneumatic massage and support for the user's legs. However, in this embodiment, the leg area 1a is provided with a leg airbag groove 11, and the leg airbag component 2 is detachably disposed within the leg airbag groove 11; the air source component 3 is disposed within the leg airbag groove 11, located below the leg airbag component 2. Therefore, when maintaining the air source component 3, the leg airbag component 2 can be disassembled from the mattress base 1, facilitating maintenance of the air source component 3 and allowing the mattress 100 to accommodate the leg airbag component 2 for pneumatic massage and support of the user's legs, thus addressing the issue of the mattress 100's inability to provide pneumatic massage and support for the user's legs.

[0047] In some embodiments, the air source assembly 3 is detachably mounted to the mattress base 1. Exemplarily, the air source assembly 3 is mounted in the leg airbag recess 11 by screws or bolts, thereby enabling detachable mounting of the air source assembly 3. When maintaining the air source assembly 3, it can be removed from the mattress base 1, facilitating maintenance.

[0048] In some embodiments, please refer to Figure 3 The leg airbag assembly 2 includes a leg sub-airbag 21 and a leg airbag mounting pad 22. The leg sub-airbag 21 is mounted on the leg airbag mounting pad 22, and the leg airbag mounting pad 22 is detachably mounted on the mattress base 1. Exemplarily, the leg airbag mounting pad 22 is interference-fitted with the leg airbag groove 11. For example, the length and width of the leg airbag mounting pad 22 are greater than the length and width of the leg airbag groove 11, respectively, so that the leg airbag mounting pad 22 is embedded in the leg airbag groove 11, achieving an interference fit and detachable installation. Optionally, the leg airbag mounting pad 22 is made of plastic, with good hardness and a certain degree of elasticity, capable of supporting the installation of the leg sub-airbag 21 and interfering with the leg airbag groove 11. In some other embodiments, the leg airbag mounting pad 22 is mounted in the leg airbag groove 11 by screws or bolts. In some other embodiments, the leg airbag mounting pad 22 and the leg airbag groove 11 can also be clearance-fitted or transition-fitted.

[0049] In some embodiments, please refer to Figure 3 The leg airbag assembly 2 includes multiple leg sub-airbags 21, arranged sequentially along the length of the mattress base 1. It is understandable that when the leg airbag assembly 2 includes only one large airbag, the inflated leg airbag assembly 2 is quite tall, and its top is curved, resulting in a small contact area with the user's legs and excessive support height, leading to a poor user experience. Reducing the inflation volume of the leg airbag assembly 2 can lower its inflated height and increase the contact area with the user, but this results in insufficient support and a poor user experience. By using multiple leg sub-airbags 21, the top of the inflated leg airbag assembly 2 forms a supporting plane, and the inflated height of each individual leg sub-airbag 21 is reduced, thus lowering the overall height of the inflated leg airbag assembly 2. This increases the contact area with the user's legs and reduces the support height, improving the user experience. Optionally, the leg airbag assembly 2 includes two leg sub-airbags 21.

[0050] It is understandable that the length of the mattress base 1 is the length of the user's body when the user lies flat on the mattress 100 in the preset sleeping position. The preset sleeping position is the position intended for the user to lie flat when the mattress 100 is manufactured. When the user lies flat in the preset sleeping position, they usually have the best sleep experience.

[0051] In some embodiments, multiple leg sub-airbags 21 are fluidly connected to the air source assembly 3, which independently controls the inflation and deflation of each leg sub-airbag 21. By independently controlling the inflation and deflation of each leg sub-airbag 21, the leg airbag assembly 2 can form different support surfaces according to the user's needs, improving the user experience. Furthermore, by independently controlling the inflation and deflation of each leg sub-airbag 21, the leg airbag assembly 2 can support or massage the corresponding position of the leg according to the user's needs. Moreover, it improves the problem of the leg airbag assembly 2 having deviations in its support position for the user's legs or failing to support the user's legs. For example, different users have different heights. Taking the example that all users' heads are aligned with the head area 1c of the mattress base 1, taller users can be supported by leg sub-airbags 21 farther from the head area 1c, while shorter users can be supported by leg sub-airbags 21 closer to the head area 1c. Alternatively, if there is a deviation between the user's position and the preset sleeping position, the user's legs will be supported by leg sub-airbags 21 corresponding to the user's leg position. For example, if the user's position is closer to the head region 1c, support can be provided by the leg sub-airbags 21 that are closer to the head region 1c; if the user's position is closer to the leg region 1a, support can be provided by the leg sub-airbags 21 that are farther from the head region 1c.

[0052] In some embodiments, please refer to Figure 2 At least two leg airbag assemblies 2 are spaced apart along the width of the mattress base 1. It is understood that the width of the mattress base 1 is perpendicular to its length, and when two users are lying flat in a preset sleeping position, the distance between them is along the width of the mattress base 1. By providing at least two leg airbag assemblies 2 spaced apart along the width of the mattress base 1, they can be used to support the legs of two or more users, allowing each user to receive leg support according to their needs. Optionally, the mattress 100 includes two leg airbag assemblies 2.

[0053] In some embodiments, please refer to Figure 2 and Figure 3The mattress 100 also includes a torso airbag assembly 4, which is located in the torso area 1b. An air source assembly 3 is fluidly connected to the torso airbag assembly 4 and is used to inflate and deflate the torso airbag assembly 4. By inflating and deflating the torso airbag assembly 4, the support height of the torso airbag assembly 4 for the user's torso can be adjusted, improving the user experience of the mattress 100. When the air source assembly 3 repeatedly inflates and deflates the torso airbag assembly 4, the torso airbag assembly 4 repeatedly expands and contracts to massage the user's torso.

[0054] In some embodiments, please refer to Figure 2 and Figure 3 The mattress base 1 has a trunk airbag groove 12, and the trunk airbag assembly 4 is installed in the trunk airbag groove 12. The trunk airbag groove 12 facilitates the positioning and installation of the trunk airbag assembly 4.

[0055] In some embodiments, please refer to Figure 3 The torso airbag assembly 4 includes a torso sub-airbag 41 and a torso airbag mounting pad 42. The torso sub-airbag 41 is mounted on the torso airbag mounting pad 42, and the torso airbag mounting pad 42 is interference-fitted with the torso airbag groove 12. Exemplarily, the length and width of the torso airbag mounting pad 42 are greater than the length and width of the torso airbag groove 12, respectively, so that the torso airbag mounting pad 42 is embedded in the torso airbag groove 12, achieving an interference fit and detachable installation. Optionally, the torso airbag mounting pad 42 is made of plastic, possessing good hardness and a certain degree of elasticity, capable of supporting and mounting the torso sub-airbag 41 and interfering with the torso airbag groove 12. In some other embodiments, the torso airbag mounting pad 42 is mounted in the torso airbag groove 12 by screws or bolts. In some other embodiments, the torso airbag mounting pad 42 and the torso airbag groove 12 may also have a clearance fit or a transition fit.

[0056] In some embodiments, please refer to Figure 3The torso airbag assembly 4 includes multiple torso sub-airbags 41, arranged sequentially along the length of the mattress base 1. It is understandable that when the torso airbag assembly 4 includes only one large airbag, the inflated height of the torso airbag assembly 4 is relatively high, and the top is curved, resulting in a small contact area with the user's torso and excessive support height, leading to a poor user experience. Reducing the inflation volume of the torso airbag assembly 4 can lower its inflated height and increase the contact area with the user, but this results in insufficient support and a poor user experience. By using multiple torso sub-airbags 41, the top of the inflated torso airbag assembly 4 forms a supporting plane, and the inflated height of each individual torso sub-airbag 41 is reduced, thus lowering the overall height of the inflated torso airbag assembly 4. This increases the contact area with the user's torso and reduces the support height, improving the user experience. Optionally, the torso airbag assembly 4 includes ten torso sub-airbags 41.

[0057] In some embodiments, multiple torso sub-airbags 41 are fluidly connected to the air source assembly 3, which independently controls the inflation and deflation of each torso sub-airbag 41. By independently controlling the inflation and deflation of each torso sub-airbag 41, the torso airbag assembly 4 can form different support surfaces according to the user's needs, improving the user experience. By independently controlling the inflation and deflation of each torso sub-airbag 41, the torso airbag assembly 4 can support or massage corresponding positions of the torso according to the user's needs.

[0058] In some embodiments, please refer to Figure 2 At least two torso airbag assemblies 4 are spaced apart along the width of the mattress base 1. By providing at least two torso airbag assemblies 4 spaced apart along the width of the mattress base 1, they can be used to support the torso of two or more users, allowing each user to receive torso support according to their own needs. Optionally, the mattress 100 includes two torso airbag assemblies 4.

[0059] In some embodiments, please refer to Figure 2 and Figure 3 The mattress 100 also includes a head airbag assembly 5, which is located in the head area 1c. An air source assembly 3 is fluidly connected to the head airbag assembly 5 and is used to inflate and deflate the head airbag assembly 5. By inflating and deflating the head airbag assembly 5, the support height of the head airbag assembly 5 for the user's head can be adjusted, improving the user experience of the mattress 100.

[0060] In some embodiments, please refer to Figure 2 and Figure 3The mattress base 1 has a head airbag groove 13, and the head airbag assembly 5 is installed in the head airbag groove 13. The head airbag groove 13 facilitates the positioning and installation of the head airbag assembly 5.

[0061] In some embodiments, please refer to Figure 2 At least two head airbag assemblies 5 are spaced apart along the width of the mattress base 1. By providing at least two head airbag assemblies 5 spaced apart along the width of the mattress base 1, they can be used to support the heads of two or more users, allowing each user to provide head support according to their own needs. Optionally, the mattress 100 includes two head airbag assemblies 5.

[0062] In some embodiments, please refer to Figure 3 The head airbag assembly 5 includes a head sub-airbag 51 and a head support pad 52. The head sub-airbag 51 is located below the head support pad 52 and is used to drive the head support pad 52 to move up and down. When the head airbag assembly 5 is fully inflated, it has a high degree of rigidity, resulting in a poor user experience due to direct contact with the user; when the head airbag assembly 5 is underinflated, it has a low degree of rigidity and insufficient support. The head support pad 52 is used to contact the user, improving the problem of poor user experience caused by direct contact with the head airbag assembly 5. The head airbag assembly 5 is made of a soft material, such as sponge or fabric. Optionally, multiple head sub-airbags 51 are arranged at the bottom of the head support pad 52 to enhance the stability of the support for the head support pad 52.

[0063] In some embodiments, the head support pad 52 slides against the inner wall of the head airbag groove 13. Exemplarily, the length and width of the head support pad 52 are equal to the length and width of the head airbag groove 13, respectively, so that the head support pad 52 is embedded in the head airbag groove 13, achieving a sliding fit. The length and width of the head support pad 52 can be slightly smaller than the length and width of the head airbag groove 13, for example, by 1 cm or 2 cm. The sliding fit between the head support pad 52 and the inner wall of the head airbag groove 13 makes the lifting and lowering movement of the head support pad 52 more stable and reliable.

[0064] In some embodiments, please refer to Figure 2 and Figure 3 The mattress 100 also includes a knee airbag assembly 6, which is located in the knee area 1d. An air source assembly 3 is fluidly connected to the knee airbag assembly 6 and is used to inflate and deflate the knee airbag assembly 6. By inflating and deflating the knee airbag assembly 6, the support height of the knee airbag assembly 6 for the user's knee can be adjusted, improving the user experience of the mattress 100. When the air source assembly 3 repeatedly inflates and deflates the knee airbag assembly 6, the knee airbag assembly 6 repeatedly expands and contracts to massage the user's knee.

[0065] The knee airbag assembly 6 inflates and deflates under the action of the air source assembly 3, providing support for the user's knee when needed, allowing the knee to lift upwards and the hip bone to rotate backwards, thereby simultaneously releasing the muscles in the user's lower back and the back of the knee. This improves the problem of muscle tension in the user's lower back and the back of the knee, enhances the user's sleep comfort, and alleviates the muscle soreness caused by the mattress 100.

[0066] For the knee airbag assembly 6 mentioned above, please refer to Figure 5 The knee airbag assembly 6 includes multiple knee sub-airbags 61, arranged sequentially along the length of the mattress base 1. It is understandable that when the knee airbag assembly 6 includes only one large airbag, the inflated height of the knee airbag assembly 6 is relatively high, and the top is curved, resulting in a small contact area with the user's knee and excessive support height, leading to a poor user experience. Reducing the inflation volume of the knee airbag assembly 6 can decrease its inflated height and increase the contact area with the user, but this results in insufficient support and a poor user experience. By using multiple knee sub-airbags 61, the top of the inflated knee airbag assembly 6 forms a supporting plane, and the inflated height of each individual knee sub-airbag 61 is reduced, thus lowering the overall inflated height of the knee airbag assembly 6. This increases the contact area with the user's knee and reduces the support height, improving the user experience. Optionally, the knee airbag assembly 6 includes three knee sub-airbags 61.

[0067] In some embodiments, please refer to Figure 5 The knee airbag assembly 6 also includes a first layer 62, on which multiple knee sub-airbags 61 are arranged sequentially and at intervals along the length of the mattress base 1. The multiple knee sub-airbags 61 are connected as a single unit via the first layer 62, thus fixing their relative positions and facilitating the arrangement and disassembly of the knee airbag assembly 6. Optionally, the first layer 62 may be a rubber layer or a rigid plastic plate.

[0068] In some other embodiments, please refer to Figure 5The knee airbag assembly 6 includes a first layer 62 and multiple second layers 63. The multiple second layers 63 are sequentially spaced apart from the first layer 62 along the length of the mattress base 1, forming a sealed cavity with the first layer 62. Exemplarily, the edges of the second layers 63 are bonded to the first layer 62, for example, by adhesive or heat-pressing, thereby forming a sealed cavity between the first layer 62 and the second layers 63, thus forming the knee sub-airbag 61. Forming the knee airbag assembly 6 by bonding layered materials reduces the production cost of the knee airbag assembly 6; and the multiple knee sub-airbags 61 are connected as one unit through the first layer 62, making the positions of the multiple knee sub-airbags 61 relatively fixed, facilitating the arrangement and disassembly of the knee airbag assembly 6. Optionally, the first layer 62 and the second layer 63 are rubber layers.

[0069] The knee airbag assembly 6 can be deflated to a thin layer. When the user needs to elevate their knee, the knee airbag assembly 6 can be inflated to elevate the knee; when the user is lying on their side, supine, or does not need to elevate their knee, the knee airbag assembly 6 can be deflated to a thin layer, without affecting the supine or flat position of the mattress 100. Furthermore, when the knee airbag assembly 6 is deflated to a thin layer, it does not affect the use of the leg airbag assembly 2.

[0070] In some embodiments, multiple knee sub-airbags 61 are fluidly connected to the air source assembly 3, which independently controls the inflation and deflation of each knee sub-airbag 61. By independently controlling the inflation and deflation of each knee sub-airbag 61, the knee airbag assembly 6 can adjust its support position according to the user's knee position, improving the problem of the knee airbag assembly 6's support position being inaccurate or failing to support the user's knee. For example, different users have different heights. Taking the user's head position as being aligned with the head area 1c of the mattress base 1, taller users can be supported by knee sub-airbags 61 farther from the head area 1c, while shorter users can be supported by knee sub-airbags 61 closer to the head area 1c. Alternatively, if there is a deviation between the user's position and the preset sleeping position, the user's knee is supported by knee sub-airbags 61 corresponding to the user's knee position. The knee sub-airbags 61 closer to the user's knee position can be controlled to have a higher support height, thus forming a mountain-shaped support structure to conform to the user's elevated knee shape.

[0071] In some embodiments, please refer to Figure 2 The knee region 1d extends into the trunk region 1b, meaning that part of the knee airbag assembly 6 is located within the trunk region 1b.

[0072] In some embodiments, please refer to Figure 2 and Figure 3At least two knee airbag assemblies 6 are spaced apart along the width of the mattress base 1. By providing at least two knee airbag assemblies 6 spaced apart along the width of the mattress base 1, they can be used to support the knees of two or more users, allowing each user to receive knee support according to their needs. Optionally, the mattress 100 includes two knee airbag assemblies 6.

[0073] In some embodiments, please refer to Figure 1 and Figure 2 The mattress 100 also includes a mattress body 7, which is positioned above the mattress base 1 and covers the leg airbag assembly 2. The leg airbag assembly 2 has a relatively high firmness when inflated, resulting in a poor user experience due to direct contact with the user. The mattress body 7 is designed to address this issue of poor user experience caused by direct contact with the leg airbag assembly 2. The mattress body 7 is made of a soft material, such as sponge or fabric.

[0074] In some embodiments, the pad 7 covers at least one of the leg airbag assembly 2, the torso airbag assembly 4, the head airbag assembly 5, and the knee airbag assembly 6. This improves the poor user experience caused by direct contact with at least one of the leg airbag assembly 2, the torso airbag assembly 4, the head airbag assembly 5, and the knee airbag assembly 6.
