Description

Technical Field

[0001] The utility model relates to an airbag in the field of bedding, in particular to an airbag with ventilation holes and a mattress. Background Art

[0002] Many bedding articles such as mattresses or pillows use inflatable and deflatable airbags to provide elastic support or massage functions. These airbags themselves lack a breathable structural design. When placed in a mattress or a pillow, it will cause the cushion layers sandwiched on both sides of the airbag to be airtight, resulting in sultriness and poor ventilation, which affects the comfort and experience of using the mattress or the pillow. Summary of the Utility Model

[0003] In order to solve the technical problem that the airbags used in existing bedding articles lack a breathable structure, resulting in poor ventilation of the cushion layers on both sides of the airbag, and thus affecting the comfort and experience of using the bedding, the utility model provides an airbag with ventilation holes and a mattress. By providing ventilation holes on the airbag, the air permeability on both sides of the airbag is improved, and thus the comfort and experience of using the bedding with airbags are enhanced.

[0004] The technical solution adopted by the utility model to solve the technical problem: An airbag with ventilation holes includes an inflatable and deflatable bladder. An air nozzle communicating with the bladder cavity is provided on the wall of the bladder. The feature is that a ventilation hole passage penetrating through the bladder cavity is provided on the bladder. The ventilation hole passage is sealed and separated from the bladder cavity. Both ends of the ventilation hole passage extend to two opposite walls of the bladder to form two openings. By providing a ventilation hole passage that penetrates through the bladder cavity in a sealed manner on the bladder, the airbag has a ventilation effect. When the airbag is used in a mattress or a pillow and is sandwiched between other cushion layers, the cushion layers on both sides of the airbag can also be ventilated, achieving many effects such as ventilation and heat dissipation, and enhancing the comfort and experience in using the bedding with airbags.

[0005] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: A through-tube with two open ends is penetrated through the bladder. The lumen of the through-tube forms the ventilation hole passage. The open ends at both ends of the through-tube are hermetically fixed to the through holes opened on two opposite walls of the bladder respectively. A through-tube with two open ends is penetrated through the bladder, and the lumen of the through-tube is used as the ventilation hole passage of the airbag. The open ends at both ends of the through-tube are hermetically fixed to the through holes opened on two opposite wall surfaces of the bladder respectively, so that the ventilation hole passage is sealed and separated from the bladder cavity. The inflation and deflation of the bladder cavity and the ventilation of the ventilation hole passage are independent of each other.

[0006] Preferably, the through-tube is made of a rigid material. The through-tube can be processed with a rigid material different from the bladder to prevent the through-tube from deforming due to the increased internal air pressure in the bladder cavity when the airbag is inflated, resulting in the reduction of the lumen diameter for ventilation or even blockage, which affects the ventilation effect.

[0007] Preferably, the bladder is a hollow cuboid, which is formed by closing two long side walls on both sides, two short side walls at both ends, a top wall and a bottom wall. The inner cavity of the cuboid forms the bladder cavity. The air nozzle is arranged on any one of the short side walls. The air pipe is inserted along the height direction perpendicular to the extending direction of the cuboid. The two open ends of the air pipe are hermetically fixed to the through holes opened on the top wall and the bottom wall respectively through a second welded edge. A plurality of air pipes are inserted along the length direction of the cuboid. The bladder is in the shape of a hollow cuboid and is formed by closing two long side walls, two short side walls, a top wall and a bottom wall. The inner cavity serves as the bladder cavity. The air nozzle is on one of the short side walls. The air pipe is inserted along the height direction of the cuboid, and the height direction is perpendicular to the extending direction of the cuboid. This makes it possible to arrange more air pipes along the length direction of the cuboid. More air pipes arranged in a row can further enhance the air permeability of the airbag and at the same time divide the airbag into several interconnected small deformation zones, making it more stable and comfortable for the mattress or pillow to support the body. The open ends at both ends of the air pipe are hermetically fixed to the two through holes opened on the top wall and the bottom wall respectively. The inserted air pipes do not affect the airtightness of the airbag, and the air vent channels and the bladder cavity are independent of each other.

[0008] Preferably, a shaping structure is arranged in the inner cavity of the cuboid to pull the two long side walls when the bladder cavity is inflated, preventing the inner cavity from bulging outwards on the plane perpendicular to the bulging working direction. The shaping structure pulls the two long side walls when the inner cavity is inflated to shape the cavity, avoiding the ineffective outward bulging of the cavity outside the preset bulging working direction, and making the deformation generated by inflation concentrate on the outward bulging in the required working direction, improving the inflation utilization rate and the effect of elastic support / massage.

[0009] Preferably, the shaping structure includes at least one long pulling piece that pulls the two long side walls. The two long side edges of the long pulling piece are fixedly connected to the corresponding two long side walls through a third welded edge. The third welded edge continuously extends along the length direction of the long side wall. The air pipe passes through the opening provided on the long pulling piece. The shaping structure is continuously welded to the two long side walls through the long pulling piece to pull the two long side walls and shape the cavity, avoiding the outward bulging of the two long side walls during inflation. The air pipe passes through the opening on the long pulling piece, so that the air vent channel and the long pulling piece do not interfere with each other and work independently.

[0010] Preferably, the two ends of the long pulling piece are connected to the two short side walls through a fourth welded edge. The fourth welded edge continuously extends along the length direction of the short side wall. The two ends of the long pulling piece are also welded to the short side walls on the same side respectively to pull the two short side walls at both ends of the cuboid and shape the cavity, avoiding the outward bulging of the two short side walls during inflation.

[0011] Preferably, the third welding edge and the fourth welding edge are respectively parallel to the length directions of the long side wall and the short side wall, and are shorter than the lengths of the corresponding long side wall and short side wall. Both the third welding edge and the fourth welding edge are parallel to the length directions of the connected corresponding long side wall and short side wall, and at the same time, their lengths are shorter, avoiding the formation of a continuous closed loop between the entire periphery of the long pull tab and the inner wall of the cavity to cause sealing isolation, so that the cavities on the upper and lower sides of the long pull tab are separated and not connected to each other. The air filled by the air nozzle can freely enter the remaining cavity spaces on the upper and lower sides of the long pull tab through the gaps remaining at the non-welded parts of the edge of the long pull tab, ensuring uniform and rapid inflation of the cavity.

[0012] Preferably, there are two long pull tabs, and the two long pull tabs hold the long side wall and the short side wall parallel to each other up and down. The air outlet of the air nozzle on the inner wall of the cavity is located between the two long pull tabs. There are two long pull tabs, which are arranged parallel to each other up and down in the cavity, and jointly hold the long side wall and the short side wall of the cavity, so that the cavity is shaped during inflation; the air outlet of the air nozzle on one side of the cavity is also located between the two long pull tabs, and during inflation, it diffuses evenly and rapidly from between the two long pull tabs to both sides of the long pull tabs and fills up.

[0013] The second object of the invention of the present utility model is to provide a mattress, which is provided with an airbag inside, and is characterized in that the airbag is the airbag with air holes described in any one of the foregoing. Through the air hole channels on the airbag, when the mattress is in the inflation operation, by using the ventilation and air permeability effect brought by the air hole channels to the airbag, good ventilation and air permeability are also achieved between the cushions arranged on both sides of the airbag, thereby realizing the effects of ventilation and heat dissipation, and improving the use comfort and experience of the mattress with an airbag.

[0014] The beneficial technical effects of the present utility model: By providing air hole channels that penetrate the air cavity through the airbag body, the airbag has the effect of ventilation and air permeability. When the airbag is used in a mattress or a pillow and is sandwiched between other cushions, ventilation and air permeability can also be achieved between the cushions on both sides of the airbag, thereby realizing effects such as ventilation and heat dissipation, and improving the use comfort and experience of the bedding with an airbag.

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0023] As Figures 1 - 5 shown, Embodiment 1 is an airbag with ventilation pores, including an inflatable and deflatable bladder 1. An air nozzle 2 communicating with the bladder cavity 1-1 is provided on the wall of the bladder 1. A ventilation pore channel 3 passing through the bladder cavity 1-1 is arranged on the bladder 1. The ventilation pore channel 3 is hermetically separated from the bladder cavity 1-1. Both ends of the ventilation pore channel 3 extend to two opposite walls of the bladder 1 to form two openings.

[0024] During use, because there is a ventilation pore channel sealed through the bladder cavity on the bladder, the airbag has the effect of ventilation and air permeability. When the airbag is used in a mattress or a pillow and sandwiched between other cushions, the cushions on both sides of the airbag can also be ventilated and air permeable, thereby achieving the effects of ventilation and heat dissipation, making the bedding with the airbag more comfortable to use and having a better sleeping experience.

[0025] Furthermore, a vent pipe 4 with two open ends is inserted through the bladder 1. The vent pipe 4 is made of a rigid material to ensure that the lumen is unobstructed and does not deform. As Figure 2 shown, the vent pipe 4 is made by bending and curling a sheet material and then welding. The lumen of the vent pipe 4 forms the ventilation pore channel 3. The two open ends at both ends of the vent pipe 4 are hermetically fixed to the through holes 5 opened on two opposite walls of the bladder 1 respectively. The bladder 1 in this embodiment is a horizontally placed hollow cuboid as shown in the figure. The cuboid is formed by closing two long side walls 6 on both sides, two short side walls 7 at both ends, a top wall 8 and a bottom wall 9. The long inner cavity forms the bladder cavity 1-1. The air nozzle 2 is arranged on any one of the short side walls 7. As shown in the figure, the vent pipe 4 is inserted along the height direction of the cuboid, and this height direction is perpendicular to the extension direction of the cuboid. The two open ends of the vent pipe 4 are hermetically fixed to the through holes 5 opened on the top wall 8 and the bottom wall 9 respectively through the second welding edge 10. Multiple vent pipes 4 are inserted along the length direction of the cuboid. In this embodiment, preferably 8 vent pipes are evenly spaced and aligned in a row.

[0026] The cuboid in this embodiment is formed by splicing a sheet material 17 with four folding segments and two flat sheets 18. As Figure 6The shown sheet 17 is curled and connected into a cylinder with both ends open through the first welding edge 14. The four folding segments respectively form the four faces of the cylinder. The four faces are two opposite long side walls 6 of a cuboid and the upper and lower top walls 8 and bottom walls. 8 through holes 5 with matching positions and the same quantity are opened on the top wall and the bottom wall for arranging the ventilation pipes 4 to make ventilation channels. Fixing ears 16 for installing air bags in a mattress or a pillow are also arranged at both ends of the bottom wall. Two flat sheets 18 are as Figure 3 shown in are respectively connected to both ends of the cylinder through the fifth welding edge 15 and seal the openings to form two short side walls of the cuboid. The air nozzle is arranged on one of the flat sheets.

[0027] Furthermore, a shaping structure is arranged in the inner cavity of the cuboid to pull the two long side walls 6 when the air bag cavity 1-1 is inflated, preventing the inner cavity from bulging outwards in the plane perpendicular to the bulging working direction. Specifically, the shaping structure includes at least one long pulling sheet 11 that pulls the two long side walls 6. In this embodiment, two parallel upper and lower pulling sheets 11 that pull the long side walls 6 and the short side walls 7 are preferably used. The air outlet of the air nozzle 2 on the inner wall of the cavity is located between the two long pulling sheets 11. The two long side edges 11-1 of the long pulling sheet 11 and the corresponding two long side walls 6 are fixedly connected through the third welding edge 12. The third welding edge 12 continuously extends along the length direction of the long side wall 6. The 8 ventilation pipes 4 pass through the corresponding 8 openings arranged in a row on the long pulling sheet 11. The two ends of the long pulling sheet 11 are connected to the two short side walls 7 through the fourth welding edge 13. The fourth welding edge 13 continuously extends along the length direction of the short side wall 7.

[0028] The shaping structure shapes the rectangular cavity by pulling the two long side walls and the two short side walls, preventing the cavity from bulging outwards invalidly in the direction other than the preset bulging working direction. In this embodiment, it shows invalid lateral bulging outwards, so that the deformation generated by inflation is concentrated on bulging outwards in the required working direction, improving the inflation utilization rate and the effect of elastic support / massage.

[0029] Furthermore, the third welding edge 12 and the fourth welding edge 13 are respectively parallel to the length directions of the long side wall 6 and the short side wall 7, and are shorter than the lengths of the corresponding long side wall 6 and short side wall 7. The third welding edge and the fourth welding edge along the periphery of the long pulling sheet are both shorter than the lengths of the butting walls, which can effectively prevent the long pulling sheet from being continuously welded along the periphery in a circle and forming a closed loop with the inner wall of the cavity to cause sealing isolation, separating the cavities on the upper and lower sides of the long pulling sheet and making them not communicate. The air filled into the cavity by the air nozzle can freely enter the cavity spaces on both sides of the long pulling sheet from the gaps without welding positions at the edge of the long pulling sheet, ensuring uniform and rapid inflation inside the cavity.

[0030] Embodiment 2 is a mattress, which is provided with an airbag inside. The airbag is the airbag with ventilation holes described in Embodiment 1. Since there are multiple ventilation channels on the airbag, when the mattress is inflated, the ventilation channels can bring the effect of ventilation and air permeability to the airbag, and also enable good ventilation and air permeability between the cushions arranged on both sides of the airbag, thereby achieving the effects of ventilation and heat dissipation, and improving the comfort and experience of using the mattress.
