Refer to FIG. 1 and FIG. 2, the inflatable bed includes a bed body 1, the bed body 1 includes a top sheet 11, a perimeter wall 12, a bottom sheet 13, and tensioning straps 4 (see FIG. 3), the top sheet 11 and the bottom sheet 13 are both disposed like a sheet, the perimeter wall 12 is open, the top sheet 11 and the bottom sheet 13 cover the perimeter wall 12 up and down and are fixed to the perimeter wall 12 by hot melting to form a cuboid-like structure. There are a plurality of tensioning straps 4, one end of each of the tensioning straps 4 is fixed to a side wall of the top sheet 11, the other ends of the tensioning straps 4 are fixed to a side wall of the bottom sheet 13, and the plurality of tensioning straps 4 are matched to play a role in stabilizing the bed body 1. In the present embodiment, the bed body 1 can be made of a PVC material, has certain deformability and can be adaptively adjusted in form during use so as not to be easily damaged. In the present embodiment, the tensioning straps 4 are set to be of rectangular-ambulatory-plane structures, rectangular ambulatory planes are connected to the top sheet 11 and the bottom sheet 13 in a length direction, the top sheet 11 is in contact with a human body to achieve concave-convex comfort, and the bottom sheet 13 is abutted against the ground to achieve stability. In other embodiments, the tensioning straps 4 can also be set to be shaped like spiral ropes or flat wires. At the same time, flock embossing 111 is formed on an upper surface of the top sheet 11, so that the water absorption property, waterproofness and retractility of the bed body 1 can be indirectly improved.

(13) On the other hand, two sets of inner supporting assemblies 2 are disposed inside the bed body 1, and the two sets of inner supporting assemblies 2 are symmetrically disposed about the bed body 1. Specifically, each of the inner supporting assemblies 2 includes an inner supporting structure 21 and a breathable mesh 22, the top of the inner supporting structure 21 is fixed to an inner wall of the top of the bed body 1, a side wall of the inner supporting structure 21 is fixed to an inner side wall of the bed body 1, and the inside of the bed body 1 is partitioned into an independent main cavity and an auxiliary cavity surrounding the main cavity by the inner supporting structure 21.

(14) Correspondingly, in the present embodiment, the inner supporting structure 21 is disposed as a PVC film or a thermoplastic urethane (TPU) film, so that the inner supporting structure 21 has certain malleability and can be adaptively adjusted in form during use so as not to be easily damaged. At the same time, the inner supporting structure 21 is good in fitting effect, high in welding firmness, not easy to crack in weld joint and long in service life when being thermally welded with the bed body 1.

(15) Refer to FIG. 2 and FIG. 3, further, the inner supporting structure 21 includes four support sheets 211 which are sequentially connected end to end, a folded portion 2112 is formed at a connection of adjacent support sheets 211, and thus, the inner supporting structure 21 has four folded portions 2112 in total, and the four folded portions 2112 are spaced in a circumferential direction of the inner supporting structure 21. The four support sheets 211 are spliced end to end, and the folded portion 2112 is formed at the connection between the two adjacent support sheets 211, so that the folded portion 2112 of the inner supporting structure is shaped like an isosceles trapezoid when being unfolded and is high in stability, strong in supporting performance, and remarkable in pressure resistance.

(16) On the other hand, each of the support sheets 211 is provided with a rectangular assembling through-hole 2111, there is one folded portion 2112 between two adjacent assembling through-holes 2111, each of the support sheets 211 is provided with a rectangular breathable mesh 22, and each of the breathable meshes 22 shields the corresponding assembling through-hole 2111, so that the main cavity communicates with the auxiliary cavity through mesh openings in the breathable mesh 22. It should be understood that the breathable mesh 22 can be fixed to the inner supporting structure 21 by thermal welding, and the breathable mesh 22 is firmly combined with the inner supporting structure 21. In the present embodiment, the inner supporting structure 21 can be formed by respectively welding the four support sheets 211 end to end, that is, the four independent support sheets 211 are processed firstly, then, the four support sheets 211 are spliced end to end, and thermal welding is performed at an end-to-end splicing part.

(17) In addition, when the breathable mesh 22 and the inner supporting structure 21 are assembled, the breathable mesh 22 can be thermally welded on the inner supporting structure 21 firstly, then, corresponding positions on the inner supporting structure 21 are cut according to a shape of an outer contour of the breathable mesh 22 to form the assembling through-holes 2111, and the mesh openings in the breathable mesh 22 are located in an area defined by the assembling through-holes 2111, and the mesh openings can drive the main cavity and the auxiliary cavity. If the breathable mesh 22 and the inner supporting structure 21 are assembled in such a way, before thermal fixation, the inner supporting structure 21 is of an overall structure and is not provided with the assembling through-holes 2111, so that the structural strength is high, deformation is not easy to occur, a good locating effect and more tight combination with the breathable mesh 22 are achieved, and the firmness of connection between the breathable mesh 22 and the inner supporting structure 21 is improved. The assembling through-holes 2111 are formed by processing after the breathable mesh 22 is fixed to the inner supporting structure 21, and it is not easy to misplace the breathable mesh 22 and the assembling through-holes 2111, and the matching quality is high.

(18) In the present embodiment, the breathable mesh 22 is made of a fiber material, that is, the breathable mesh 22 is a fiber mesh, for example, the breathable mesh 22 can be a chemical fiber mesh, a polyester mesh, etc.

(19) In addition, a side wall of the bed body 1 is provided with a built-in air pump 3, and the built-in air pump 3 is used for inflation. Specifically, the built-in air pump 3 includes a mounting plate 31 and a pump body 32, the mounting plate 31 is mounted on the side wall of the bed body 1, and the pump body 32 is built in the main cavity.

(20) The inflatable bed in the embodiment of the present application is implemented based on a principle that, during use, a sufficient amount of gases can be filled into the main cavity by means of the pump body 32, and the gases in the main cavity can directly enter the auxiliary cavity through the mesh openings in the breathable mesh 22, so that air pressures of the main chamber and the auxiliary cavity are kept consistent. The auxiliary cavity is disposed around the main cavity and is located around the bed body 1 so as to be capable of enhancing the strength around the bed body 1. During use, great collapse around the bed body 1 is not easy to occur, a situation that a user or items located on the bed body 1 slide down from the bed body 1 due to the collapse around the bed body 1 can be avoided, and comfort and safety in use are achieved. After inflation is completed, the inner supporting structure 21 and the breathable mesh 22 are matched to provide a tension, so that the shape of the bed body 1 is kept fixed. It should be understood that the deformability of the inner supporting structure 21 is higher than the deformability of the breathable mesh 22, and therefore, when the inner supporting structure 21 is connected to the bed body 1, the effect of fitting the inner supporting structure 21 to the bed body 1 is good, the strength of a connection position is high, cracks or direct separation or other situations are not easy to occur on the connection position, and the service life is long. At the same time, the breathable mesh 22 is disposed on the inner supporting structure 21, the intercommunication between the main cavity and the auxiliary cavity is achieved by the mesh openings in the breathable mesh 22, the deformability of the breathable mesh 22 is relatively weak, and the breathable mesh 22 plays a role in enhancing the strength of the inner supporting structure 21 and can provide a stable tension, thereby effectively inhibiting the extensibility and malleability of the inner supporting structure 21 and the bed body 1. The inner supporting structure 21 is not easy to deform when being tensioned, the phenomena of swelling and bulging around the bed body 1 due to tension failure or excessive air pressure or other factors are not easily caused, and the bed body 1 is high in stability, long in service life, and high in comfort in use.

Embodiment 2

(21) Refer to FIG. 4 and FIG. 5, the embodiment is different from Embodiment 1 in that four corners of the inner supporting structure 21 are all provided with reinforcing airbags 5, and the reinforcing airbags 5 are used for supporting four corners of the bed body 1. In the present embodiment, the reinforcing airbags 5 are also made of a PVC film or TPU film, are of film-like structures with unilateral openings, and are fixed to the inner supporting structure 21 by thermal welding.

(22) Correspondingly, the side wall of the inner supporting structure 21 is provided with gas ports 212, the gas ports 212 communicate with the reinforcing airbags 5, and one-way air nozzles 2121 are mounted at the gas ports 212. Since volumes of the reinforcing airbags 5 are smaller, gases are delivered into the reinforcing airbags 5 through the one-way air nozzles 2121 only after inflation for the main cavity and the auxiliary cavity is completed, the one-way air nozzles 2121 can reduce the situation that gases entering the reinforcing airbags 5 easily flow out from the main cavity because the reinforcing airbags 5 are extruded, and then, the structural strength of the reinforcing airbags 5 can be ensured.

(23) In addition, with the increase of service time, a small amount of partial gases in the reinforcing airbags 5 can also flow out from the one-way air nozzles 2121. Therefore, during repeated use, the gases in the reinforcing airbags 5 can be supplemented when the main cavity and the auxiliary cavity are inflated.

(24) Further, sections of the reinforcing airbags 5 are set to be triangular, and triangular structures have certain stability, so that the structural stability of the reinforcing airbags 5 is further improved. In addition, an inner side wall of the perimeter wall 12 is provided with locating slots 121 in a vertical direction, and side walls of the reinforcing airbags 5 abut against and matched with side walls of the locating slots 121, thereby limiting the displacement of the reinforcing airbags 5 in a horizontal direction, and further improving the stability of the reinforcing airbags 5. When the inflatable bed is inflated repeatedly, the reinforcing airbags 5 are inserted into the locating slots 121 to play a role in location. At the same time, when the inflatable bed is stored, the reinforcing airbags 5 can retain original triangular plate-like structures, which is convenient for a user to rapidly recognize positions of the four corners of the inflatable bed to achieve rapid storage during storage. In addition, after the inflatable bed is stored, the reinforcing airbags 5 can play an inner supporting role and provide a certain shaping ability for an overall structure of the stored and folded inflatable bed to reduce the situation that the folded inflatable bed is softer and needs to be supported when being fetched by the user, thereby further improving the user convenience of the inflatable bed.

(25) Refer to FIG. 4 and FIG. 6, on the other hand, a connecting rod 6 is rotatably borne on the side wall of the mounting plate 31 and is disposed in a length direction of the bed body 1, one end of the connecting rod 6 penetrates out of the mounting plate 31 on which a self-locking knob is disposed, and the connecting rod 6 is coaxially fixed to the self-locking knob. At the same time, an end of the connecting rod 6 is vertically fixed with a supporting rod 7, and the supporting rod 7 is used for supporting upper and lower inner walls of the bed body 1. Specifically, ends of the supporting rod 7 are fixed with arc-shaped plates 8, and side walls of the arc-shaped plates 8 abut against and matched with the inner wall of the bed body 1.

(26) Therefore, the mounting plate 31 is used for bearing the pump body 32, the supporting rod 7 is matched with the arc-shaped plates 8 to support an area where the built-in air pump 3 is located, and the arc-shaped plates 8 can disperse a pressure borne during uniform dispersion, have good pressure resistance, and reduce the situation that the user applies an overhigh pressure to the built-in air pump 3 to damage the built-in air pump 3 when using the bed body 1. At the same time, by rotating the connecting rod 6, an angle of the supporting rod 7 can be changed, and when the inflatable bed is deflated and stored, space relatively occupied by the supporting rod 7 can be reduced.

(27) The embodiment of the present application is implemented based on the approximately same principle as Embodiment 1 so as not to be repeated too much herein.

(31) It should be noted that the skin-friendly top layer 11a is in direct contact with the skin, and therefore, a soft, breathable and skin-friendly material should be selected. For example, pure cotton, bamboo fiber, tencel, and other natural fibers can be adopted. In the embodiment of the present application, the skin-friendly top layer 11a is made of the pure cotton which is capable of effectively absorbing sweat on the surface of the skin, keeping the skin dry and comfortable, also having the characteristics of softness and skin friendliness and providing excellent comfort.

(32) In addition, by disposing the filling layer 12a, external cold and heat can be effectively isolated, the temperature of the bed body 1 can be kept, and heat insulation properties of the bedcover 1a can be improved. For example, down, wool, memory cotton, latex and other materials can be adopted. In the present embodiment, the filling layer 12a is made of the memory cotton capable of effectively isolating the external cold and heat, keeping the temperature of the bed body 1, also having the characteristics of softness and elasticity and providing good support and comfort.

(33) Therefore, the skin-friendly top layer 11a is in direct contact with the skin, and can provide excellent comfort and ensure that a user has good sleep experience. By disposing the filling layer 12a, the external cold and heat can be effectively isolated, the temperature of the bed body 1 can be kept, and the heat insulation properties of the bedcover 1a can be improved. The base layer 13a can prevent the bed body 1 from being worn, prolong the service life of the bed body 1, also prevent a filler inside the bed body 1 from being externally exposed, and keep the bed body 1 clean. Due to the design of the binding 14a, an edge of the bedcover 1a is neater, the beauty of the bedcover 1a is increased, at the same time, the displacement of the skin-friendly top layer 11a, the filling layer 12a and the base layer 13a is avoided, and the shape of the bedcover 1a is kept.

(35) Therefore, the upper zipper tape 11b of the connecting zipper 1b is fixed to the side wall of the binding 14a, the lower zipper tape 12b is fixed to the surface of the top sheet 11, and the zipper slider 13b is used for zipping the upper zipper tape 11b and the lower zipper tape 12b, so that tight connection between the bedcover 1a and the top sheet 11 is ensured, and at the same time, the bedcover 1a is conveniently detached and cleaned.

(36) It should be noted that the connecting zipper 1b in the embodiment of the present application is correspondingly provided with two ends, i.e., a head and a tail of the connecting zipper 1b. After the head and the tail of the connecting zipper 1b are enclosed, the head of the connecting zipper 1b further extends forwards and correspondingly covers an outer side of the tail of the connecting zipper 1b, so that the tail of the connecting zipper 1b is isolated from an external environment to play a protection role. At the same time, when the inflatable bed is inflated, both the bedcover 1a and the bed body 1 deform, at the moment, the head of the connecting zipper 1b may move due to the above-mentioned deformation, so that cracks appear at a connection between the bedcover 1a and the bed body 1. By appropriately extending a segment of the head of the connecting zipper 1b, a displacement margin can be provided for the head of the connecting zipper 1b, the situation of cracks at the above-mentioned connection between the bedcover 1a and the bed body 1 can be reduced, and the stability of connection between the bedcover 1a and the bed body 1 can be ensured.
