Description

Technical Field

[0001] The present application relates to the field of inflatable mattresses, and in particular to a sponge-mat inflatable bed. Background Art

[0002] Inflatable beds are popular for outdoor activities and home use because of their portability and easy storage. Traditional inflatable beds usually consist of a large inflatable chamber, which is inflated by an air pump and other equipment when in use, and can be deflated and stored when not in use, making them easy to carry and store. However, this type of traditional inflatable bed has problems such as a single structure and low comfort. Especially after long-term use, the bed is prone to sag due to uneven inflation and local air leakage, affecting the use effect. To solve this problem, inflatable beds with layered designs have appeared on the market. Layered inflation is achieved through two upper and lower inflatable chambers, reducing the possibility of bed depression due to uneven local inflation of one inflatable chamber.

[0003] However, it is difficult to ensure balanced inflation of the upper and lower inflation chambers in an inflatable bed with a layered design. The unbalanced inflation of the upper and lower inflation chambers may reduce the stability of the inflatable bed during use and reduce the use effect. Utility Model Content

[0004] In order to solve the problem of stable inflation of an inflatable bed, the present application provides a sponge pad inflatable bed.

[0005] The present application provides a sponge pad inflatable bed adopting the following technical solution:

[0006] A sponge pad inflatable bed, comprising a top sheet, a bottom sheet, and side surrounding sheets, wherein the top sheet, the bottom sheet, and the side surrounding sheets are arranged to form a bed body, wherein a partition is arranged in the bed body, and the edges of the partition are connected to the side surrounding sheets to divide the bed body into an upper cushion layer and a lower inflatable layer, wherein a sponge pad is arranged in the upper cushion layer;

[0007] The lower air-inflating layer is provided with a pumping air assembly, the upper cushion layer is provided with a first air nozzle, and the spacer is provided with at least one one-way air nozzle, and the one-way air nozzle is used to limit the gas to flow from the upper cushion layer into the lower air-inflating layer in one direction.

[0008] By adopting the above technical solution, the upper cushion layer with a sponge pad provides a soft and comfortable bed surface that can absorb and disperse the user's weight pressure; the lower inflatable layer mainly plays a supporting and cushioning role, so that the inflatable bed has good stability during use, and the bed will not sink too much due to the user's weight. The one-way air nozzle can ensure that the gas only flows from the upper cushion layer to the lower inflatable layer in one direction. Even if the upper cushion layer is partially deformed due to use or external pressure, the gas in the bed can only flow into the lower inflatable layer, and will not flow back to the upper cushion layer, ensuring the stability and comfort of the bed.

[0009] When inflating the lower inflatable layer, only the lower inflatable layer is inflated, and the inflated gas will not flow from the lower inflatable layer to the upper cushion layer, ensuring that the lower inflatable layer is fully inflated and the upper cushion layer is not easily over-inflated to cause the surface to bulge. This enables the lower inflatable layer to provide better stability for the bed body and the upper cushion layer to provide excellent comfort, improving the comfort and convenience of use. During use, the first air nozzle of the upper cushion layer can be opened to allow outside air to enter the upper cushion layer and then into the micropores of the sponge pad, ensuring that the air pressure inside the upper cushion layer is consistent with the outside air pressure and making the upper cushion layer soft and comfortable.

[0010] When the lower inflatable layer is deflated through the air pumping component, the first air nozzle of the upper cushion layer is closed. Due to the air pressure difference between the lower inflatable layer and the upper cushion layer, the gas inside the upper cushion layer flows into the lower inflatable component through the one-way air nozzle, realizing simultaneous deflation of the upper cushion layer and the lower inflatable layer, facilitating folding and storage of the inflatable bed.

[0011] Meanwhile, the upper cushion layer and the lower inflatable layer of the present application can provide two surfaces with different hardnesses, similar to the function of using both sides of a household mattress. It can be used on both sides, and has a small storage volume, which is convenient for transportation.

[0012] Optionally, the four peripheral edges of the top sheet are connected to the top of the side surround sheet, the four peripheral edges of the bottom sheet are connected to the bottom of the side surround sheet, and the four peripheral edges of the spacer sheet are connected to the middle of the side surround sheet. The top sheet, the spacer sheet and the side surround sheet enclose to form the upper cushion layer, and the bottom sheet, the spacer sheet and the side surround sheet enclose to form the lower inflatable layer.

[0013] By adopting the above technical solution, the connection of each sheet of the bed body is stable, and the upper cushion layer and the lower inflatable layer formed by enclosing are structurally stable, presenting a relatively flat bed body structure with high use comfort.

[0014] Optionally, the side surround sheet includes an upper side surround sheet and a lower side surround sheet. The bottom of the upper side surround sheet is connected to the top of the lower side surround sheet. The four peripheral edges of the spacer sheet are connected to the connection part of the upper side surround sheet and the lower side surround sheet. The four peripheral edges of the top sheet are connected to the top of the upper side surround sheet, and the four peripheral edges of the bottom sheet are connected to the bottom of the lower side surround sheet. The upper side surround sheet, the top sheet and the spacer sheet enclose to form the upper cushion layer, and the lower side surround sheet, the bottom sheet and the spacer sheet enclose to form the lower inflatable layer.

[0015] By adopting the above technical solution, the height of the upper side surround sheet and the height of the lower side surround sheet can be set according to the required height of the upper cushion layer and the required height of the lower inflatable layer, and the height of the bed body can be flexibly adjusted to meet the sleep needs of different people.

[0016] Optionally, the first air nozzle is arranged on the upper side surround sheet, and the air pumping component is arranged on the lower side surround sheet.

[0017] By adopting the above technical solutions, stable air flow can be achieved in the upper cushion layer, and stable inflation and deflation operations can be achieved in the lower inflation layer, with high practicability; moreover, the first air nozzle and the air pumping assembly are both arranged on the side surround of the bed body, which does not affect the sleep comfort of the bed body surface and the placement stability of the bottom surface.

[0018] Optionally, a plurality of drawbands are arranged in the lower inflation layer, one end of each drawband is connected to the partition, and the other end of the drawband is connected to the bottom sheet.

[0019] By adopting the above technical solutions, the structural stability of the lower inflation layer can be enhanced, and the phenomenon of bed body deformation or damage caused by long-term use or over-inflation can be prevented.

[0020] Optionally, annular capacity-increasing sheets are extended and arranged at the four peripheral edges of the top sheet, one side of the annular capacity-increasing sheet far from the top sheet is connected to the middle part of the outer surface of the side surround, the four peripheral edges of the partition are connected to the top of the side surround, and the four peripheral edges of the bottom sheet are connected to the bottom of the side surround; the top sheet, the annular capacity-increasing sheets, the partition and the side surround enclose to form the upper cushion layer, and the bottom sheet, the partition and the side surround enclose to form the lower inflation layer.

[0021] When a drawband structure is arranged in the lower inflation layer, after the lower inflation layer is inflated, the drawbands will stretch the partition connected to their top and the bottom sheet connected to their bottom inward, so as to improve the stability of the lower inflation layer; but at the same time, since the partition is tractionally stretched by the drawbands and partially concave inward appears, the top view projection area of the partition is reduced, and the partition is tractionally pulled by the drawbands to drive the four peripheral edges of the partition to be pulled toward the middle, so that the connection part between the partition and the side surround is pulled and stretched toward the middle of the partition, and the longitudinal section of the side surround presents a "3"-shaped structure. The traction force received by the side surround will affect the four peripheral edges of the top sheet to be pulled downward, so that the top sheet and the sponge pad present an upward-arching arch radian, reducing the flatness of the upper surface of the bed body and reducing the use comfort, stability and safety.

[0022] Therefore, by adopting the above technical solutions, the partition is connected to the top of the side surround, and the annular capacity-increasing sheet is connected to the middle part of the outer surface of the side surround, which can cover part of the side surround, so that when the partition is tractionally pulled by a plurality of drawbands, the partition is pulled toward the inside of the lower inflation layer, the side surround is pulled toward the middle of the partition, and the annular capacity-increasing sheet can cover the part of the side surround deformed by traction, so that the side surround is still relatively flat in appearance and has no obvious "3"-shaped longitudinal section structure; on the other hand, the annular capacity-increasing sheet is extended from the four peripheral edges of the top sheet, increasing the original area of the top sheet, so that when the top sheet is tractionally pulled by the partition and the side surround, the annular capacity-increasing sheet provides a buffer area for downward traction and stretching, so that the top sheet is relatively flat and does not present an obvious upward-arching arc deformation, improving the use stability and comfort of the air bed.

[0023] Optionally, the side enclosure piece includes an upper side enclosure piece and a lower side enclosure piece. The bottom of the upper side enclosure piece is connected to the top of the lower side enclosure piece. The four peripheral edges of the spacer are connected to the top of the upper side enclosure piece. The four peripheral edges of the annular volume increasing piece are connected to the connection part between the upper side enclosure piece and the lower side enclosure piece, and the annular volume increasing piece is arranged on the outer surface of the upper side enclosure piece. The four peripheral edges of the bottom sheet are connected to the bottom of the lower side enclosure piece. The top sheet, the annular volume increasing piece, the spacer and the upper side enclosure piece enclose to form the upper cushion layer. The bottom sheet, the spacer, the upper side enclosure piece and the lower side enclosure piece enclose to form the lower inflation layer.

[0024] By adopting the above technical solution, the height of the lower side enclosure piece can be set according to the required height of the lower inflation layer, and the position of the annular volume increasing piece at the connection part between the upper side enclosure piece and the lower side enclosure piece can be set according to the required height of the upper cushion layer, so that the height of the bed body can be flexibly adjusted to meet the sleep needs of different people.

[0025] Optionally, the first air nozzle is arranged on the top sheet, and the air pumping assembly is arranged on the lower side enclosure piece.

[0026] By adopting the above technical solution, when lying on the inflatable bed, it is relatively convenient to control the opening and closing of the first air nozzle at the top sheet, and the operation is convenient. Preferably, the first air nozzle is arranged at the corner of the top sheet, so that the first air nozzle will not cause a foreign body feeling to the human sleep area when using the inflatable bed, and the use comfort is improved.

[0027] Optionally, the one-way air nozzle is arranged on one side of the spacer close to the air pumping assembly.

[0028] By adopting the above technical solution, the path for the gas in the upper cushion layer to flow into the lower inflation assembly through the one-way air nozzle is shorter, the air extraction efficiency of the upper cushion layer and the lower inflation layer is improved, and the use is convenient.

[0029] Optionally, the air pumping assembly is an air pumping integrated device and / or a second air nozzle.

[0030] By adopting the above technical solution, the inflation and deflation operations of the lower inflation layer are diversified. The air pumping integrated device can be set according to the application scenario requirements of the inflatable bed to realize inflation and deflation in one; the second air nozzle can also be set, and other separate external inflation and deflation integrated pumps can be connected to the second air nozzle to inflate or extract and deflate the lower inflation layer; the air pumping integrated device and the second air nozzle can also be set at the same time, and the inflation and deflation operations are diversified.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. The one-way air nozzle provided in this application can ensure that the gas only flows into the lower inflatable layer unidirectionally from the upper cushion layer. When inflating the bed body, only the lower inflatable layer is inflated, ensuring the support and buffering functions of the lower inflatable layer, without inflating the upper cushion layer, thus avoiding the surface of the upper cushion layer bulging due to over-inflation. When deflating the bed body, the gas in the upper cushion layer flows into the lower inflatable component through the one-way air nozzle, realizing the simultaneous deflation of the upper cushion layer and the lower inflatable layer, facilitating the folding and storage of this inflatable bed.

[0033] 2. This application preferably uses a pull belt to connect the spacer and the bottom sheet of the lower inflatable layer, enhancing the durability of the bed body and providing diverse connection methods to adapt to different usage environments.

[0034] 3. The upper cushion layer and the lower inflatable layer of this application can provide two surfaces with different hardnesses, similar to the function of a household mattress that can be used on both sides. It can be used on either side, and has a small storage volume, facilitating transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The following is further detailed description of this application in conjunction with the attached Figure 1-21 drawings.

[0058] The embodiment of this application discloses an inflatable bed with a sponge pad.

[0059] Embodiment 1

[0060] Referring to Figure 1-2 , the inflatable bed with a sponge pad includes a top sheet 1, a spacer 2, a bottom sheet 3, and a side surround sheet 4. The side surround sheet 4 is a one-piece structure. The four peripheral edges of the top sheet 1 are connected to the top of the side surround sheet 4, and the four peripheral edges of the bottom sheet 3 are connected to the bottom of the side surround sheet 4. The above connection methods are preferably connected to each other by hot melting or bonding processes to form the basic structure of the bed body 100. Further, the four peripheral edges of the spacer 2 are connected to the middle of the side surround sheet 4, and are also preferably connected by hot melting or bonding processes, so that the top sheet 1, the spacer 2, and the side surround sheet 4 enclose to form an upper cushion layer 101, and the bottom sheet 3, the spacer 2, and the side surround sheet 4 enclose to form a lower inflatable layer 102; preferably, the connection position of the spacer 2 on the side surround sheet 4 can be set according to the required height of the upper cushion layer 101 and the required height of the lower inflatable layer 102.

[0061] Further, referring to Figure 2-3 , the spacer 2 is provided with at least one check valve 8. The check valve 8 is a common check valve structure on the market. Specifically, as Figure 4-5 , the check valve 8 includes a connecting seat 81 and a check diaphragm 81. The outer wall of the connecting seat 81 is provided with a connecting ring 84, and the connecting ring 84 is arranged along the circumferential direction of the connecting seat 81. Preferably, the connecting ring 84 is arranged on the upper surface of the spacer 2, so that the connecting seat 81 can be stably connected to the spacer 2, and the connection stability between the check valve 8 and the bed body 100 is improved.

[0062] A through hole 811 is formed in the middle of the connecting seat 81. The through hole 811 penetrates through the two surfaces of the connecting seat 81. A connecting disc 83 is provided on the hole wall of the connecting seat 81 corresponding to the through hole 811. Specifically, the connecting disc 83 is integrally connected to the connecting seat 81. The connecting disc 83 is provided with a connecting hole 831 and a plurality of ventilation holes 832. The one-way diaphragm 81 covers the plurality of ventilation holes 832. A connecting column 821 is provided on one surface of the one-way diaphragm 81. Specifically, the connecting column 821 is provided on the top of the one-way diaphragm 81, that is, the connecting column 821 is provided on the surface of the one-way diaphragm 81 close to the upper cushion layer 101. Preferably, the connecting column 821 is integrally formed with the one-way diaphragm 81 and is preferably made of soft rubber material. Further, an annular groove 822 is formed in the middle of the connecting column 821 along its circumferential direction, so that the top of the soft connecting column 821 can pass through the connecting hole 831 by slightly deforming, and then the annular groove 822 is clamped in the connecting hole 831. The top of the connecting column 821 is limited to the top of the connecting disc 83, and the axial length of the annular groove 822 is greater than the thickness of the connecting disc 83, so that the part of the connecting column 821 corresponding to the annular groove 822 can move relatively in the connecting hole 831. When the one-way diaphragm 81 abuts against the bottom of the connecting disc 83, the one-way diaphragm 81 seals the plurality of ventilation holes 832, so that gas cannot flow from the bottom of the connecting disc 83 to the top of the connecting disc 83. When the one-way diaphragm 81 is away from the bottom of the connecting disc 83, the one-way diaphragm 81 releases the seal of the ventilation holes 832, so that there is a gap between the bottom of the connecting disc 83 and the one-way diaphragm 81, which is convenient for gas to flow from the top of the connecting disc 83 to the bottom of the connecting disc 83.

[0063] Looking back Figure 1-2 , in the upper cushion layer 101, a sponge pad 5 is provided. The height of the sponge pad 5 is slightly higher than the distance between the top sheet 1 and the spacer sheet 2, so that the upper cushion layer 101 can stably cover the sponge pad 5. When in use, the sponge pad 5 provides a soft and comfortable touch for the inflatable bed. At the same time, a first air nozzle 7 is provided on one side wall of the upper cushion layer 101 (that is, the position of the side surround sheet 4 corresponding to the upper cushion layer 101). The first air nozzle 7 is a common air nozzle structure on the market and can maintain the air flow between the outside and the upper cushion layer 101. When using the inflatable bed, the first air nozzle 7 is opened, so that outside air flows into the upper cushion layer 101 and into the micropores of the sponge pad 5 to ensure that the air pressure in the upper cushion layer 101 is balanced with the outside air pressure.

[0064] In the lower inflatable layer 102, a plurality of pull straps 9 are provided. One end of the pull strap 9 is connected to the spacer sheet 2, and the other end of the pull strap 9 is connected to the bottom sheet 3. The pull strap 9 can be a wire pull strap, a sheet pull strap, a hole pull strap or an annular pull strap, etc., and can all realize the stable function of the pull strap 9 in the lower inflatable layer 102. Among them, as Figure 5 shown, the wire pull strap is a cord-like pull strap, so that a plurality of dot-like structures are presented on the outer surface of the bottom sheet 3; as Figure 6-7As shown, the sheet pull belt is a pull belt in the shape of a sheet, and its opposite side edges are respectively connected to the spacer 2 and the bottom sheet 3, so that a plurality of linear structures are presented on the outer surface of the bottom sheet 3. The plane where the sheet pull belt is located is parallel to the length direction or the width direction of the bed body 100; as Figure 8-9 shown, the hole pull belt is formed by connecting the ends of a strip-shaped sheet with a certain width to form a quasi-elliptical structure, and the width direction of the end of the strip-shaped pull belt is connected to the spacer 2 and the bottom sheet 3, so that a plurality of quasi-circular structures are presented on the outer surface of the bottom sheet 3. The width direction of the strip-shaped sheet of the hole pull belt is parallel to the length direction or the width direction of the bed body 100; as Figure 10-11 shown, the annular pull belt is formed by connecting the ends of a strip-shaped sheet to form a quasi-elliptical structure, and the width of the strip-shaped sheet is the same as the height of the lower inflatable layer 102. The side edges of the strip-shaped sheet can be arranged along the length direction or the width direction of the inflatable bed, so that a plurality of elliptical structures are presented on the outer surface of the bottom sheet 3. The length direction of the strip-shaped sheet of the hole pull belt is parallel to the length direction or the width direction of the bed body 100.

[0065] Meanwhile, a pumping air assembly 6 is arranged on the side wall of the lower inflatable layer 102 (i.e., the position where the side enclosure sheet 4 corresponds to the lower inflatable layer 102). The pumping air assembly 6 is a pumping air integrated device 61 and / or a second air nozzle 62. The pumping air integrated device 61 is a common air pump structure with integrated inflation and air extraction functions on the market, and the second air nozzle 62 is a common air nozzle structure on the market, which can be connected to an external pumping air device to inflate or deflate the lower inflatable layer 102. Preferably, the side wall of the lower inflatable layer 102 can be provided with both the pumping air assembly 6 and the second air nozzle 62, or only the pumping air assembly 6, or only the second air nozzle 62, all of which are within the protection scope of this application.

[0066] When the air pumping and integrating device 61 and the second air nozzle 62 are both set, the air pumping and integrating device 61 and the second air nozzle 62 can be set on the side surround piece 4 on the same side of the lower inflatable layer 102, or can be respectively set on the side surround pieces 4 on different sides of the lower inflatable layer 102; the first air nozzle 7 and the second air nozzle 62 can be set on the side surround piece 4 on the same side of the bed body 100, or can be set on the side surround pieces 4 on different sides of the bed body 100; the air pumping and integrating device 61 and the first air nozzle 7 can be set on the side surround piece 4 on the same side of the bed body 100, or can be set on the side surround pieces 4 on different sides of the bed body 100; that is, the first air nozzle 7, the second air nozzle 62 and the air pumping and integrating device 61 can be set on the side surround piece 4 on the same side of the bed body 100 or the side surround pieces 4 on different sides of the bed body 100, all within the scope of implementation of this application. The one-way air nozzle 8 is preferably set on one side of the partition 2 close to the air pumping and integrating device 61 and / or the second air nozzle 62. More preferably, the one-way air nozzle 8 is set close to the air extraction end of the air pumping and integrating device 61 of the partition 2, with high air extraction efficiency, which is convenient for the gas in the upper cushion layer 101 to be timely extracted through the air pumping component 6 and then separated from the external environment, improving the overall air extraction and storage operation of the inflatable bed.

[0067] The implementation principle of Embodiment 1 is as follows: Fix the first air nozzle 7, the second air nozzle 62 and the air pumping and integrating device 61 on the corresponding side walls of the side surround piece 4 according to the required positions, and set the one-way air nozzle 8 on the partition 2. Specifically, the side with the connecting column 821 of the one-way diaphragm 81 is set facing upwards; then connect the top of the pulling belt 9 to the lower surface of the partition 2, connect the bottom of the pulling belt 9 to the upper surface of the bottom sheet 3, then connect the four peripheral edges of the bottom sheet 3 to the bottom of the side surround piece 4, connect the four peripheral edges of the partition 2 to the middle of the side surround piece 4, and specifically set the side of the partition 2 with the one-way air nozzle 8 close to the side wall of the side surround piece 4 with the air pumping and integrating device 61 and / or the second air nozzle 62. Preferably, the one-way air nozzle 8 is set close to the air extraction end of the air pumping and integrating device 61 of the partition 2, thus forming the lower inflatable layer 102. Similarly, first place the sponge pad 5 on the upper surface of the partition 2, and then connect the four peripheral edges of the top sheet 1 to the top of the side surround piece 4, thus forming the upper cushion layer 101. Finally, remove the scraps at each connection, and then the sponge pad inflatable bed is manufactured.

[0068] When the sponge pad air bed needs to be used, open the first air nozzle 7 so that external air can freely enter the upper cushion layer 101 and can flow into the micropores of the sponge pad 5, so that the air pressure in the upper cushion layer 101 is balanced with the external air pressure; and connect with the second air nozzle 62 through an external air pumping device, or directly through the air inflation function of the integrated air pumping device 61, and inflate the lower inflation layer 102. The inflated air fully circulates inside the lower inflation layer 102 and will not flow into the upper cushion layer 101 through the one-way air nozzle 8, then the inflation of the sponge pad air bed is completed. When in use, the first air nozzle 7 can be kept open or closed.

[0069] When the sponge pad air bed does not need to be used, close the first air nozzle 7 and exhaust the air in the lower inflation layer 102 through the second air nozzle 62. When storing, the air in the upper cushion layer 101 and the micropores of the sponge pad 5 can be squeezed. While rolling up, squeeze. The air squeezed from the upper cushion layer 101 flows through the one-way air nozzle 8 into the lower inflation layer 102, then the exhaust and storage can be realized. In addition, it can also be connected with the second air nozzle 62 through an external air pumping device, or directly through the air extraction function of the integrated air pumping device 61 to quickly extract the gas in the lower inflation layer 102 to the outside. When the lower inflation layer 102 is exhausted by air extraction, the lower inflation layer 102 is in a negative pressure state. The pressure difference between the upper cushion layer 101 and the lower inflation layer 102 makes the air in the upper cushion layer 101 and the micropores of the sponge pad 5 flow through the one-way air nozzle 8 into the lower inflation layer 102, and then the air extraction of the upper cushion layer 101 and the lower inflation layer 102 can be carried out simultaneously, and the gas in the upper cushion layer 101 and the lower inflation layer 102 can be fully exhausted, which is more convenient for the folding and rolling up of the sponge pad air bed, and the volume of folding and rolling up is smaller.

[0070] Embodiment 2

[0071] Refer to Figure 12 , the difference between this embodiment and Embodiment 1 is that the side surround piece 4 in this embodiment is composed of two side surround pieces 4, specifically including an upper side surround piece 41 and a lower side surround piece 42. The bottom of the upper side surround piece 41 is connected to the top of the lower side surround piece 42. The four peripheral edges of the top piece 1 are connected to the top of the upper side surround piece 41. The bottom of the upper side surround piece 41 and the top of the lower side surround piece 42 are both connected to the four peripheral edges of the partition piece 2, that is, the four peripheral edges of the partition piece 2 are connected to the connection part between the bottom of the upper side surround piece 41 and the top of the lower side surround piece 42. The four peripheral edges of the bottom piece 3 are connected to the bottom of the lower side surround piece 42, and the above connection methods are preferably connected to each other by hot melting or bonding processes to enclose and form the upper cushion layer 101 and the lower inflation layer 102. Preferably, the height of the upper side surround piece 41 and the height of the lower side surround piece 42 can be set according to the required height of the upper cushion layer 101 and the required height of the lower inflation layer 102, and the height of the upper side surround piece 41 is slightly lower than the height of the sponge pad 5.

[0072] In addition, the first air nozzle 7 is provided on one side wall of the upper side panel 41, and a pumping air integrated device 61 and / or a second air nozzle 62 are provided on the side wall of the lower side panel 42. Specifically, the lower side panel 42 may be provided with both the pumping air assembly 6 and the second air nozzle 62, or only the pumping air assembly 6, or only the second air nozzle 62, all of which are within the protection scope of this application.

[0073] When both the pumping air integrated device 61 and the second air nozzle 62 are provided, the pumping air integrated device 61 and the second air nozzle 62 may be provided on the same side wall of the lower side panel 42, or may be respectively provided on different side walls of the lower side panel 42; the first air nozzle 7 and the second air nozzle 62 may be provided on the side panels 4 on the same side of the bed body 100, that is, the side wall of the upper side panel 41 where the first air nozzle 7 is provided and the side wall of the lower side panel 42 where the second air nozzle 62 is provided are both located on the same side of the bed body 100; the first air nozzle 7 and the second air nozzle 62 may be provided on the side panels 4 on different sides of the bed body 100, that is, the side wall of the upper side panel 41 where the first air nozzle 7 is provided and the side wall of the lower side panel 42 where the second air nozzle 62 is provided are respectively located on different sides of the bed body 100; the pumping air integrated device 61 and the first air nozzle 7 may be provided on the side panels 4 on the same side of the bed body 100, that is, the side wall of the upper side panel 41 where the first air nozzle 7 is provided and the side wall of the lower side panel 42 where the pumping air integrated device 61 is provided are both located on the same side of the bed body 100; the pumping air integrated device 61 and the first air nozzle 7 may be provided on the side panels 4 on different sides of the bed body 100, that is, the side wall of the upper side panel 41 where the first air nozzle 7 is provided and the side wall of the lower side panel 42 where the pumping air integrated device 61 is provided are both located on different sides of the bed body 100; that is, the first air nozzle 7, the second air nozzle 62, and the pumping air integrated device 61 may be provided on the same side or different sides of the bed body 100, all of which are within the implementation scope of this application.

[0074] The implementation principle of Embodiment 2 is as follows: Fix the required position of the first air nozzle 7 on the corresponding side wall of the upper side surround piece 41, fix the second air nozzle 62 and the air pumping integrated device 61 at the required positions on the corresponding side wall of the lower side surround piece 42, and set the one-way air nozzle 8 on the partition piece 2. Specifically, set the side with the connecting column 821 of the one-way diaphragm 81 facing upward; then connect the top of the drawstring 9 to the lower surface of the partition piece 2, connect the bottom of the drawstring 9 to the upper surface of the bottom piece 3, then connect the four peripheral edges of the bottom piece 3 to the bottom of the lower side surround piece 42, connect the top of the lower side surround piece 42 to the four peripheral edges of the partition piece 2, and specifically set the side of the partition piece 2 with the one-way air nozzle 8 close to the side wall of the lower side surround piece 42 where the air pumping integrated device 61 and / or the second air nozzle 62 are arranged. Preferably, set the one-way air nozzle 8 close to the air extraction end of the air pumping integrated device 61 of the partition piece 2, thus forming the lower inflation layer 102. Similarly, first place the sponge pad 5 on the upper surface of the partition piece 2, then connect the four peripheral edges of the top piece 1 to the top of the upper side surround piece 41, and connect the bottom of the upper side surround piece 41 to the four peripheral edges of the partition piece 2 as well, thus forming the upper cushion layer 101. Finally, remove the scraps at each connection, and then the sponge pad inflatable bed is manufactured.

[0075] The usage operation and the storage and folding operation of the sponge pad inflatable bed are the same as those in Embodiment 1 above, and will not be repeated here.

[0076] Embodiment 3

[0077] Referring to Figure 13-14 , the difference between this embodiment and Embodiment 1 is that: This embodiment is preferably applicable to an inflatable bed with a hole drawstring 9 structure; specifically, the side surround piece 4 in this embodiment is a one-piece side surround piece 4 structure, and the four peripheral edges of the partition piece 2 are connected to the top of the side surround piece 4, and the four peripheral edges of the bottom piece 3 are connected to the bottom of the side surround piece 4, so that the partition piece 2, the side surround piece 4 and the bottom piece 3 enclose to form the lower inflation layer 102.

[0078] The top sheet 1 is provided with an annular capacity increasing sheet 11 extending from its four peripheral edges. Along the length direction of the annular capacity increasing sheet 11, one side thereof is integrally connected to the four peripheral edges of the top sheet 1, and the other side is connected to the middle part of the outer surface of the side enclosure sheet 4. Specifically, the four peripheral edges of the top sheet 1 and the annular capacity increasing sheet 11 cover the upper middle part of the outer surface of the side enclosure sheet 4, so that the total area of the top sheet 1 and the annular capacity increasing sheet 11 is greater than the area of the spacer sheet 2. At this time, the top sheet 1, the annular capacity increasing sheet 11, the spacer sheet 2 and the side enclosure sheet 4 enclose and form an upper cushion layer 101. Preferably, in this embodiment, the area of the top sheet 1 in the flattened state is the same as the area of the spacer sheet 2 in the flattened state. In this embodiment, the connection manner between the annular capacity increasing sheet 11 and the outer surface of the side enclosure sheet 4 can be fixed connection manners such as welding and bonding, so that the upper cushion layer 101 has good sealing performance; or, the connection manner between the annular capacity increasing sheet 11 and the outer surface of the side enclosure sheet 4 can be detachable connection manners such as zipper connection, Velcro connection and snap connection, and can be replaced and connected according to the size requirements of the sponge pad 5.

[0079] In addition, the first air nozzle 7 is arranged on the top sheet 1, and preferably arranged at the corner of the top sheet 1. The side wall of the side enclosure sheet 4 is provided with a pumping air integrated device 61 and / or a second air nozzle 62. Specifically, the side enclosure sheet 4 can be provided with both the pumping air assembly 6 and the second air nozzle 62, or only the pumping air assembly 6, or only the second air nozzle 62, all within the protection scope of this application. When both the pumping air integrated device 61 and the second air nozzle 62 are provided, the pumping air integrated device 61 and the second air nozzle 62 can be arranged on the same side wall of the side enclosure sheet 4, or can be respectively arranged on different side walls of the side enclosure sheet 4, all within the implementation scope of this application.

[0080] The implementation principle of Embodiment 3 is as follows: Fix the required position of the first air nozzle 7 on the top sheet 1, fix the second air nozzle 62 and the pumping air integrated device 61 on the corresponding side wall of the side enclosure sheet 4 according to the required positions, and arrange the one-way air nozzle 8 on the spacer sheet 2. Specifically, the side with the connecting column 821 of the one-way diaphragm 81 is arranged upward; then connect the top of the pull belt 9 to the lower surface of the spacer sheet 2, connect the bottom of the pull belt 9 to the upper surface of the bottom sheet 3, then connect the four peripheral edges of the bottom sheet 3 to the bottom of the side enclosure sheet 4, connect the four peripheral edges of the spacer sheet 2 to the top of the side enclosure sheet 4, and specifically arrange the side of the spacer sheet 2 with the one-way air nozzle 8 close to the side wall of the side enclosure sheet 4 provided with the pumping air integrated device 61 and / or the second air nozzle 62. Preferably, the one-way air nozzle 8 is arranged close to the air extraction end of the pumping air integrated device 61 of the spacer sheet 2, then a lower inflation layer 102 is formed. Similarly, first place the sponge pad 5 on the upper surface of the spacer sheet 2, and then connect the four peripheral edges of the annular capacity increasing sheet 11 to the middle part of the outer surface of the side enclosure sheet 4, then an upper cushion layer 101 is formed. Finally, remove the scraps at each connection, and then a sponge pad air bed is manufactured.

[0081] When inflating the sponge mat air bed, the operation of opening the first air nozzle 7 to keep the air pressure in the upper cushion layer 101 balanced with the external air pressure and inflating the lower inflatable layer 102 through the air pump-integrated device 61 or the second air nozzle 62 is the same as that in Embodiment 1; the difference is that during the inflation process, the pulling belt 9 pulls the spacer 2 and the bottom sheet 3 inward. At this time, the cross-sectional projected area of the spacer 2 becomes smaller due to the traction and stretching, and the top of the side surround sheet 4 is pulled toward the middle of the spacer 2, making the upper-middle part of the side surround sheet 4 present a locally bent state, with the bending direction being toward the middle of the spacer 2. At the same time, the annular expansion sheet 11 is pulled downward and stretched. At this time, the top sheet 1 will not deform upward and arch, and can stably cover the sponge mat 5.

[0082] When storing and folding the sponge mat air bed when it is not needed, the operation is the same as that in Embodiment 1 above and will not be repeated here.

[0083] Embodiment 4

[0084] Referring to Figure 15 This embodiment is different from Embodiment 3 in that: the side surround sheet 4 in this embodiment is formed by connecting the upper side surround sheet 41 and the lower side surround sheet 42. Specifically, the bottom of the upper side surround sheet 41 is connected to the top of the lower side surround sheet 42, the four peripheral edges of the spacer 2 are connected to the top of the upper side surround sheet 41, and the four peripheral edges of the bottom sheet 3 are connected to the bottom of the lower side surround sheet 42, so that the spacer 2, the upper side surround sheet 41, the lower side surround sheet 42, and the bottom sheet 3 enclose to form the lower inflatable layer 102.

[0085] The annular expansion sheet 11 extending from the four peripheral edges of the top sheet 1 is connected to the connection part of the upper side surround sheet 41 and the lower side surround sheet 42 (the connection method can be welding, bonding, zipper connection, Velcro connection, snap connection, etc.). Specifically, the four peripheral edges of the top sheet 1 and the annular expansion sheet 11 cover the outer surface of the upper side surround sheet 41. At this time, the top sheet 1, the annular expansion sheet 11, the spacer 2, and the upper side surround sheet 41 enclose to form the upper cushion layer 101.

[0086] In addition, the first air nozzle 7 is provided on the top sheet 1, and preferably at the corner of the top sheet 1. The side wall of the lower side surround sheet 42 is provided with the air pump-integrated device 61 and / or the second air nozzle 62. Specifically, the lower side surround sheet 42 can be provided with both the air pump assembly 6 and the second air nozzle 62 at the same time, or only the air pump assembly 6, or only the second air nozzle 62, all within the protection scope of this application.

[0087] When both the air pump-integrated device 61 and the second air nozzle 62 are provided at the same time, the air pump-integrated device 61 and the second air nozzle 62 can be provided on the same side wall of the lower side surround sheet 42, or can be respectively provided on different side walls of the lower side surround sheet 42, all within the implementation scope of this application.

[0088] The implementation principle of Embodiment 4 is as follows: Fix the position of the first air nozzle 7 required on the top sheet 1, fix the second air nozzle 62 and the air pump integrated device 61 at the corresponding side walls of the lower side surround sheet 42 according to the required positions, and set the one-way air nozzle 8 on the partition sheet 2. Specifically, the side of the one-way diaphragm 81 with the connecting column 821 is set facing upward; then connect the top of the drawstring 9 to the lower surface of the partition sheet 2, connect the bottom of the drawstring 9 to the upper surface of the bottom sheet 3, then connect the four peripheral edges of the bottom sheet 3 to the bottom of the lower side surround sheet 42, connect the top of the upper side surround sheet 41 to the four peripheral edges of the partition sheet 2, and specifically set the side of the partition sheet 2 with the one-way air nozzle 8 close to the side wall of the lower side surround sheet 42 where the air pump integrated device 61 and / or the second air nozzle 62 are arranged. Preferably, the one-way air nozzle 8 is set close to the air extraction end of the air pump integrated device 61 of the partition sheet 2, thus forming the lower inflation layer 102. Similarly, first place the sponge pad 5 on the upper surface of the partition sheet 2, then connect the four peripheral edges of the annular capacity increasing sheet 11 to the connection part of the upper side surround sheet 41 and the lower side surround sheet 42, and cover the upper side surround sheet 41, thus forming the upper cushion layer 101. Finally, remove the scraps at each connection part, then the sponge pad inflatable bed is made.

[0089] When inflating the lower inflation layer 102, the drawstring 9 pulls the partition sheet 2 and the bottom sheet 3 inward. At this time, the cross-sectional projected area of the partition sheet 2 becomes smaller due to the traction and stretching, and accordingly pulls the top of the upper side surround sheet 41 toward the middle of the partition sheet 2, making the upper side surround sheet 41 present a curved state, with the bending direction toward the middle of the partition sheet 2. At the same time, the annular capacity increasing sheet 11 is pulled downward and stretched. At this time, the top sheet 1 will not show a deformed upward arching, and can stably wrap the sponge pad 5.

[0090] The storage and folding operation when the sponge pad inflatable bed is not needed is the same as that in Embodiment 3 above, and will not be repeated here.

[0091] Embodiment 5

[0092] Refer to Figure 16-18 , the difference between this embodiment and Embodiment 3 is that: the lower inflation layer 102 is provided with a first diagonal drawstring 1021 and / or a second diagonal drawstring 1022.
