Description

TECHNICAL FIELD

[0001] The utility model relates to furniture mattress technical field more specifically, and it is more specifically to an inflatable mattress. BACKGROUND

[0002] The Chinese patent with the publication number CN222397758U discloses a sponge sandwich mattress, comprising: an inflatable mattress, the outer side of the inflatable mattress is wrapped with a wrapping layer; a sponge layer, the sponge layer is arranged on the inner side of the inflatable mattress, and a plurality of hot melt adhesive films are arranged around the sponge layer; a covering layer, the covering layer is arranged on the top of the sponge layer.

[0003] The inflatable mattress of the prior art similar to the above is inflated according to the needs of different hardness of the user, and the user lies on the inflatable mattress for use.

[0004] The prior art in the above has the following defects: because the body structure of different body parts of the human body is different, the weight is also different, that is, the pressure exerted by different body parts when lying down is different, such as the weight of the hip position is greater than that of the calf position, in order to ensure the comfort, the touch hardness provided by the mattress at the hip position to the human body should be less than that of the calf, and in the case of adjusting the air pressure value of the inflatable bed single air chamber, the air pressure is the same and the overall deformation amount is limited, the support hardness felt by the hip is greater than that of the calf, thereby affecting the application comfort of the single air pressure value adjustment inflatable mattress. If the multi-chamber structure in the Chinese patent with the publication number CN108451243B is used, the multi-chamber air pressure value is adjusted for different independent air chambers, and the multi-chamber inflation and deflation adjustment needs to detect and calculate the adjustment time, and the control cost is also relatively higher than that of the single air pressure value adjustment inflatable bed. UTILITY MODEL CONTENTS

[0005] In view of the existing technical problems, the utility model aims to provide an inflatable mattress which can realize dynamic self-balancing adaptation of support effect at different positions based on single air pressure adjustment, and has the advantage of improving comfort.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] An inflatable mattress, comprising a bed cover and an inflatable body, a plurality of adjusting cavities are formed on the inflatable body, the air chambers located on the side of the adjusting cavities in the inflatable body are in communication with each other, and the bed cover is wrapped on the outer side of the inflatable body.

[0008] By adopting the technical scheme, after the air mattress is inflated as required, a user lies on the air mattress. Due to different body structures and weights of different body parts of the user, correspondingly, different body parts exert different pressures on the inflation gas when lying. The air chambers around the adjusting cavities are connected to each other, and the inflation gas at a position with a larger pressure is transferred to a position with a smaller pressure under the action of the pressure exerted by the body. Due to the provision of the gap space in the adjusting cavities, the surface area of the inflation gas is increased, and then the deformable area of the inflation gas is increased. When the human body lies on the support surface of the inflation gas, the height of the support surface changes under the action of the pressure and fits the human body curve. The inflation gas that is extruded is dispersedly applied to the adjusting cavities around the support position blocks, the adjusting cavities are deformed, the volume in the cavities of the adjusting cavities is reduced, and the deformation volumes of the adjusting cavities are different due to different weights and different pressures generated by different body parts, so that the hardness of the air mattress is self-balanced and adapted to the support blocks corresponding to the body parts; meanwhile, the free flow of the airflow in the inflation gas realizes the self-balanced and adaptive hardness of the entire air mattress support surface, and the comprehensive action of the two makes the air mattress felt by the human body softer and more elastic, so that the support effect of the air mattress at different positions under the action of the self-weight of the human body is dynamically self-adapted on the premise of only single air pressure adjustment, and finally the best comfortable support effect of the human body is approached, and the dynamic self-balancing of the hardness is realized by natural action, without the need for detection, calculation and feedback adjustment by sensors and other electronic devices, so that the reaction adjustment time is ensured to be fast and the control cost is ensured to be low.

[0009] Further, the adjusting cavities are formed along the vertical direction, side wall surfaces are formed on the inner circumferential sides of the cavities of the adjusting cavities, the upper surface of the inflation gas is a support surface, and the adjusting cavities are gap spaces extending to the support surface.

[0010] By adopting the technical scheme, the adjusting cavities are formed along the vertical direction, and the deformation direction of the side wall surfaces in the adjusting cavities is along the horizontal direction perpendicular to the vertical direction, so that the deformation range of the side wall surfaces is increased, and then the self-adaptive range of the hardness of the adjusting cavities to the human body is increased.

[0011] Further, the adjusting cavities are formed along the vertical direction, the upper surface of the inflation gas is a support surface, the adjusting cavities pass through the inflation gas in the vertical direction, and the adjusting cavities extend to the support surface and the lower surface of the inflation gas at two ends, respectively.

[0012] By adopting the technical scheme, the adjusting cavities are formed through, the area of the side wall surfaces in the adjusting cavities is further increased, the deformation range of the side wall surfaces is increased, and the self-adaptive effect of the adjusting cavities to the human body is improved.

[0013] Further, the projection shape of the adjusting cavities in the vertical direction is a polygon, and the cavities of the adjusting cavities are formed with a plurality of side wall surfaces.

[0014] By adopting the technical scheme, the adjusting cavities have multiple side wall surfaces, relative to the side wall surfaces in an integral and continuous annular shape, the mutual restriction force between the adjacent side wall surfaces in structure is reduced, the changeable change amount of the space in the adjusting cavities is improved, and the adaptive effect of the adjusting cavities on the human body support is further improved.

[0015] Further, the adjusting cavities are equidistantly formed along the side edge direction of the support surface, and the adjusting cavities are arrayed on the inflatable body.

[0016] By adopting the technical scheme, the adjusting cavities are equidistantly formed on the inflatable body and arrayed on the inflatable body, the inflatable body is divided into multiple equidistant support blocks in communication with each other, different block positions provide support for the human body structure of different body parts, and different blocks dynamically and adaptively adjust the support effect of the human body in the current position through the adjusting cavities, so that the use comfort of the inflatable mattress is ensured.

[0017] Further, the depth of the adjusting cavities in the vertical direction is greater than the width of the adjusting cavities in the horizontal direction.

[0018] By adopting the technical scheme, the width of the adjusting cavities is limited to avoid that the cavity opening is too large, so that the human body structure is completely sunk into the adjusting cavities and the flatness of the surface support of the inflatable mattress is affected.

[0019] Further, the comfort layer is laid on the support surface, and the bed cover is wrapped outside the comfort layer and the inflatable body.

[0020] By adopting the technical scheme, the comfort layer is used to further improve the soft touch when the human body lies on the surface of the inflatable mattress, and to reduce the influence of the adjusting cavities formed on the inflatable body on the flatness of the touch of the human body support surface.

[0021] Further, the sponge frame is further included, the inflatable body is placed in the sponge frame, and the side surface of the inflatable body is attached to the inner frame surface of the sponge frame.

[0022] By adopting the technical scheme, the sponge frame is used to improve the support effect of the edge of the inflatable mattress, facilitate the getting-on and getting-off actions of the human body, and enhance the flatness of the four edges of the inflatable mattress and improve the overall three-dimensionality.

[0023] Further, the sponge frame includes two inflatable bodies arranged side by side, the side surfaces of the long edges of the two inflatable bodies are adjacent, and a partition is arranged between the adjacent surfaces of the two inflatable bodies, and the bed cover is wrapped outside the sponge frame, the inflatable body and the comfort layer.

[0024] By adopting the above technical solution, two air inflators are set up and used in conjunction with separators, which reduces the mutual interference of the two users' movements in the use of a double bed, and further improves the comfort of the air mattress.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] (1) By adjusting the shape of the cavity, the deformability of the air in different areas is increased, so as to realize the dynamic adaptive support of the air for different parts of the human body. Combined with the free flow of the air chambers around the cavity, the comfort of the air mattress is improved.

[0027] (2) By adjusting the cavity to form multiple inner wall surfaces in the vertical direction, the deformability of the cavity can be further improved, thus enhancing its dynamic adaptive effect;

[0028] (3) By setting up a comfort layer and a sponge frame, the overall comfort and appearance of the air mattress are improved. Attached Figure Description

[0039] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Example 1: An air mattress, such as Figure 1 , Figure 2 As shown, the device includes a mattress cover 1 and an inflatable gas chamber 2. The inflatable gas chamber 2 has several adjustable cavities 3 formed on it. Air chambers 22 located around the adjustable cavities 3 within the inflatable gas chamber 2 are interconnected. The mattress cover 1 covers the outside of the inflatable gas chamber 2. The upper surface of the inflatable gas chamber 2 serves as a support surface 21 for the human body to lie on. When the human body lies on the support surface 21, the adjustable cavities 3 around the lying position are deformed by pressure, causing the volume of the adjustable cavities 3 to decrease. The support height of the support surface 21 then lowers to conform to the curve of the human body. Simultaneously, the free flow of air within the inflatable gas chamber 2 enables dynamic self-balancing adjustment of the hardness of the inflatable gas chamber 2 in each support area of ​​the human body and the entire support surface 21.

[0041] like Figure 2 , Figure 3 As shown, in this embodiment, the inflatable gas 2, after inflation, is cubic in shape. The adjusting cavity 3 is formed vertically on the supporting surface 21 of the inflatable gas 2, and its depth in the vertical direction is greater than its width in the horizontal direction. The adjusting cavity 3 is a gap space extending to the supporting surface 21 at one end. In this embodiment, a bottom air chamber 23 is provided at the bottom of the inflatable gas 2. One end of the adjusting cavity 3 extends through the supporting surface 21, and the other end is located on the top surface of the bottom air chamber 23. The bottom air chamber 23 is connected to the air chambers 22 on the periphery of the adjusting cavity 3. A plurality of adjusting cavities 3 are formed at equal intervals along the long and wide sides of the supporting surface 21, and the adjusting cavities 3 are arranged in an array on the inflatable gas. Preferably, the projection shape of the adjusting cavity 3 in the vertical direction is polygonal, and a side wall 31 is formed on the inner periphery of the cavity of the adjusting cavity 3. Preferably, in this embodiment, the vertical projection shape of the adjustment cavity 3 is rhomboid, with the two diagonals of the rhombus parallel to the long and short sides of the support surface 21, respectively. Each adjustment cavity 3 has four internal sidewalls 31. When the gas filling 2 is completed, the four sidewalls 31 of the adjustment cavity 3 deform under the action of air pressure into arc-shaped surfaces bulging into the cavity.

[0042] like Figure 4 As shown, a sponge frame 4 is fitted around the outer periphery of the inflatable gas 2. The inner frame of the sponge frame 4 is attached to the periphery of the inflatable gas 2. A comfort layer 5 is laid on the support surface 21 of the inflatable gas 2. The size of the comfort layer 5 is adapted to the size of the sponge frame 4 and the inflatable gas 2. The bed cover 1 covers the outer side of the sponge frame 4, the inflatable gas 2 and the comfort layer 5.

[0043] Example 2: An air mattress, such as Figure 5 , Figure 7As shown, the device includes a bed cover 1 and an inflatable gas 2. The inflatable gas 2 has several adjustable cavities 3 formed on it. The air chambers 22 located around the adjustable cavities 3 of the inflatable gas 2 are interconnected. The bed cover 1 covers the outside of the inflatable gas 2. The difference between this embodiment and Embodiment 1 is that... Figure 6 In this embodiment, the adjusting cavity 3 is vertically permeated by the inflatable gas 2, and both ends of the adjusting cavity 3 extend to the supporting surface 21 and the lower surface of the inflatable gas 2 opposite to it, respectively. In this embodiment, two inflatable gases 2 are provided, arranged side-by-side within the sponge frame 4, with their long sides adjacent. A separator 6 is provided within the sponge frame 4 between the adjacent surfaces of the two inflatable gases 2. In this embodiment, the separator 6 is a long sponge strip with the same length as the inflatable gas 2. The two inflatable gases 2 and the separator 6 are embedded within the sponge frame 4, and the mattress cover 1 covers the outside of the sponge frame 4, the inflatable gases 2, and the comfort layer 5.

[0044] Example 3: An air mattress, such as Figure 8 , Figure 9 As shown, the device includes a bed cover 1 and an inflatable gas 2. The inflatable gas 2 has several adjustable cavities 3 formed on it. The air chambers of the inflatable gas 2 located around the adjustable cavities 3 are interconnected. The bed cover 1 covers the outside of the inflatable gas 2. The difference between this embodiment and the second embodiment is that the projected shape of the adjustable cavity 3 in the vertical direction is a square. The two adjacent sides of the square are parallel to the long side and the short side of the support surface 21, respectively. In addition, each adjustable cavity 3 also has four inner wall surfaces 31 formed inside the cavity. Under the action of air pressure, the surface deforms into an arc shape that bulges into the cavity.

[0045] The working process and beneficial effects of this utility model are as follows: After the air mattress is inflated as needed, the user lies on it. Due to the different body structures and weights of different parts of the user's body, the pressure applied to different positions of the inflatable gas 2 is different when lying down. The air chambers around the adjustment cavity 3 are interconnected, and the gas in the inflatable gas 2 flows under the action of different pressures at different positions. The gap space in the adjustment cavity 3 increases the surface area of ​​the inflatable gas 2, thereby increasing the area where the inflatable gas 2 can deform.

[0046] When a person lies on the support surface 21, the height of the support surface 21 changes under pressure and conforms to the curve of the human body. The compressed gas disperses and acts on the adjustment cavity 3 around the current support position block, causing the adjustment cavity 3 to deform and its internal volume to decrease. Different body parts have different weights and generate different pressures, resulting in different changes in the deformation volume of the corresponding adjustment cavity 3. This achieves dynamic self-balancing adaptation of the support firmness of the air mattress to each body part. At the same time, the free flow of gas in the air 2 achieves self-balancing adaptation of the firmness of the entire support surface 21. The combined effect of these two factors provides a soft and elastic support experience for the human body. Thus, under the premise of only single air pressure adjustment, the support effect of the air mattress at different positions can achieve dynamic self-adaptation under the action of the human body's own weight, ultimately achieving the best comfort support for the human body. Moreover, the dynamic self-balancing adjustment of the firmness of different blocks is achieved by natural action. Compared with real-time detection and calculation of feedback to readjust the air pressure of different blocks through sensors, it ensures a faster response and adjustment time and lower control costs.

[0047] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
