Description

Technical Field

[0001] This utility model relates to the field of mattress technology, specifically to a mattress with adjustable firmness. Background Technology

[0002] Smart mattresses are becoming increasingly popular, offering users a comfortable lying experience. However, current smart mattresses can only perform a single function, requiring the body to adapt to the mattress. Therefore, a mattress that truly adapts to the body, catering to the needs of most people, including their desired firmness and comfort level, is needed. This would eliminate the need to spend time choosing a suitable mattress and achieve excellent sleep quality. However, existing smart mattresses often adjust firmness via airbags, but the adjustable range at the bottom is limited, and the protection of the airbags is poor, or it's inconvenient to maintain the protected airbags.

[0003] For example, a double-layer airbag structure mattress described in the patent with authorization announcement number CN215126488U has multiple airbags distributed in it. It is pre-inflated and then adjusted to a set air pressure value based on the pressure distribution monitored by pressure sensors. This method can only make adaptive adjustments, and the adjustable range of the bottom firmness is small. Moreover, it does not have effective protective measures for the airbags, making the airbags easy to be damaged.

[0004] Based on this, a mattress with adjustable firmness is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a mattress with adjustable firmness to solve the problems in the prior art.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, an adjustable mattress includes a protective frame 1. An airbag 11 is disposed within the inner cavity of the protective frame 1. An airbag assembly 12 is fixedly connected to the upper surface of the airbag 11, and a comfort layer 13 is fixedly connected to the upper surface of the airbag assembly 12. The airbags 11 and 12 are connected to an external air pump, either individually or separately. A protective mechanism 2 is disposed on the inner wall of the protective frame 1 near the airbag 11. Limiting mechanisms 3 are disposed on the inner walls of the protective frame 1 and the comfort layer 13 at corresponding upper and lower positions. Since the mattress is composed of four protective frames 1, preferably, one limiting mechanism 3 is disposed on each of the four protective frames 1. Similarly, preferably, the comfort layer 13 is also provided with four limiting mechanisms 3 corresponding to the four limiting mechanisms 3 on the protective frames 1. Preferably, the protective frame 1 is made of a hard material such as wood or metal.

[0027] In this embodiment, the protective mechanism 2 protects the airbag 11 and the airbag assembly 12. When the airbag 11 and the airbag assembly 12 are inflated, the protective mechanism 2 is in an extended state; when the airbag 11 and the airbag assembly 12 are deflated or leaking, the protective mechanism 2 is in a relaxed state. When maintenance of the airbag 11 and the airbag assembly 12 is required, the limiting mechanism 3 is released from limiting the protective mechanism 2, and then the airbag 11 and the airbag assembly 12 can be maintained.

[0028] In an optional embodiment, such as Figures 2-4 As shown, the protective mechanism 2 includes a protective fabric 21. First inserts 22 are uniformly distributed and fixedly connected to the lower surface of the protective fabric 21. The outer wall of the first insert 22 is inserted into the inner wall of the protective frame 1. Second inserts 23 are uniformly distributed and fixedly connected to the upper surface of the protective fabric 21. The outer wall of the second insert 23 is inserted into the inner wall of the comfort layer 13. A first fixing frame 24 is fixedly connected to the lower surface of the protective fabric 21 near the first insert 22. The outer wall of the first fixing frame 24 is inserted into the inner wall of the protective frame 1. A second fixing frame 25 is fixedly connected to the upper surface of the protective fabric 21 near the second insert 23. The outer wall of the second fixing frame 25 is inserted into the inner wall of the comfort layer 13. When… When the state of airbag 11 and airbag assembly 12 changes, the distance between comfort layer 13 and protective frame 1 changes. At this time, the protective cloth 21 is deformed, thereby protecting airbag 11 and airbag assembly 12 and preventing external objects from directly contacting airbag 11 and airbag assembly 12. When maintenance of airbag 11 and airbag assembly 12 is required, the limiting mechanism 3 is released, and then the first insert 22 and fixing frame 1 24 are removed from the inner wall of protective frame 1. At the same time, the second insert 23 and fixing frame 25 are removed from the inner wall of comfort layer 13, and then maintenance of airbag 11 and airbag assembly 12 can be performed.

[0029] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the limiting mechanism 3 includes a limiting block 31. The outer wall of the limiting block 31 is inserted into the inner wall of the protective frame 1. The outer wall of the limiting block 31 is inserted into the inner wall of the first insert block 22. A positioning block 32 is inserted into the inner wall of the limiting block 31. The outer wall of the positioning block 32 is inserted into the inner wall of the protective frame 1. A pull block 33 is fixedly connected to the outer wall of the positioning block 32. The outer wall of the pull block 33 is slidably connected to the inner wall of the protective frame 1. A spring 34 is fixedly connected to the positioning block 32 near the outer wall of the pull block 33. The other end of the spring 34 is fixedly connected to the inner cavity of the protective frame 1.

[0030] By pulling the lever 33, the user causes the positioning block 32 to slide on the inner wall of the protective frame 1 or the comfort layer 13, causing the spring 34 to contract. This causes the positioning block 32 to disengage from the inner cavity of the limiting block 31. Then, the user can pull the limiting block 31 so that the outer wall of the limiting block 31 is no longer inserted into the inner wall of the first insert 22, and then the protective mechanism 2 can be removed.

[0031] In an optional embodiment, such as Figure 2 As shown, the airbag assembly 12 consists of multiple small airbags, which are interconnected by air valves. This facilitates the subsequent adaptive pressure adjustment of the air pump in conjunction with the airbag assembly 12, making the mattress more conform to the human body.

[0032] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the protective cloth 21, the first insert 22 and the second insert 23 form a hollow rectangular frame, so that the protective cloth 21 can better protect the airbag 11 and the airbag assembly 12 as a whole, and prevent sharp objects from the outside from directly contacting the airbag 11 or the airbag assembly 12.

[0033] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the limiting block 31 has a T-shaped shape, which makes it easier to remove during installation and disassembly.

[0034] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the inner wall of the protective frame 1 is provided with sliding grooves (not shown in the figure) that are adapted to the positioning block 32 and the pull block 33. The sliding groove adapted to the pull block 33 is smaller than the sliding groove adapted to the positioning block 32. Thus, pulling the pull block 33 can drive the positioning block 32, which can prevent the positioning block 32 from coming off the inner wall of the protective frame 1.

[0035] In an optional embodiment, such as Figures 1-4 As shown, the external air pump is connected to multiple air valves in the airbag assembly 12, so that the airbag assembly 12 can be adjusted more accurately during adaptive adjustment.

[0036] The above embodiment discloses an adjustable mattress. When the firmness needs to be adjusted, an external air pump, in conjunction with air valves, can be controlled to adjust the airbags 11 as a whole, thereby changing the overall firmness of the mattress. Simultaneously, the air pump, in conjunction with the air valves on the airbag assembly 12, can adaptively adjust the pressure, making the mattress more conform to the human body. During adjustment, when the state of the airbags 11 and airbag assembly 12 changes, the distance between the comfort layer 13 and the protective frame 1 changes. At this time, the protective cloth 21 deforms, thus protecting the airbags 11 and airbag assembly 12 from direct contact with external objects, preventing damage. Furthermore, when the protective cloth 21 needs to be removed for maintenance of the airbags 11 and airbag assembly 12, pulling the pull block 33 moves the positioning block 32 to the protective frame 1 or comfort layer 13. The inner wall slides, causing the spring 34 to contract, thereby preventing the outer wall of the positioning block 32 from interlocking with the inner wall of the limiting block 31. Then, the limiting block 31 can be pulled, preventing its outer wall from interlocking with the inner wall of the first insert block 22. The first insert block 22 and the first fixing frame 24 can then be removed from the inner wall of the protective frame 1, while the second insert block 23 and the second fixing frame 25 can be removed from the inner wall of the comfort layer 13. Then, the airbag 11 and the airbag assembly 12 can be maintained. In summary, by using the airbag 11 and the airbag assembly 12 in conjunction with the air pump, the overall firmness of the mattress can be adjusted, and the mattress can be made to better fit the body according to the user's physical characteristics. During the adjustment process, the protective mechanism 2 protects the airbag 11 and the airbag assembly 12. When maintenance of the airbag 11 and the airbag assembly 12 is required, the limiting mechanism 3 is removed from the protective mechanism 2, and then the airbag 11 and the airbag assembly 12 can be maintained.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
