Description

Technical Field

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

[0002] Many bedding items such as mattresses or pillows use inflatable and deflatable airbags to provide elastic support or massage effects. Common airbags are mostly flat structures or cuboids. Flat airbags are mostly composed of a large number of monomeric small airbags densely arranged, which is troublesome to manufacture due to the large quantity; while when a larger cuboid airbag is inflated, it bulges out as a whole, but only the protruding part along the massage direction plays a massage role, and the lateral protrusion perpendicular to the massage direction has no effect on massage and will also reduce the massage effect of the airbag. Content of the Utility Model

[0003] In order to solve the technical problems in the existing bedding, such as the troublesome manufacture of flat-structured massage airbags with a large number, and the poor shape retention of cuboid airbags after being inflated as a whole, low efficiency of converting deformation into massage, and poor massage effect, the utility model provides an airbag with a massage layer. A special massage part is arranged at the top of the airbag. After the airbag is inflated, the massage part bulges outwards, and the rest of the airbag except the massage part is shaped. The inflation utilization rate is high and the massage effect is good.

[0004] The technical solution adopted by the utility model to solve the technical problems: An airbag with a massage layer includes a horizontally extending cavity. An air nozzle is arranged on the side wall of the cavity. The feature is that a plurality of massage parts are formed on the top wall of the cavity along the length direction. The massage parts can bulge upwards after the cavity is inflated, forming an upward-transmitted massage stimulation. A shaping structure is arranged in the cavity to pull the side wall of the cavity when the cavity is inflated, preventing the cavity from bulging outwards horizontally. The utility model forms a plurality of massage parts on the top wall of the cavity. When the cavity is inflated, the top wall part where the massage parts are located bulges upwards, forming an upward-transmitted massage stimulation. Compared with the existing airbag that bulges out as a whole, the massage position is more accurate and the massage effect is more obvious; at the same time, a shaping structure is arranged inside the cavity to pull the side wall of the cavity when the cavity is inflated, shaping the cavity, avoiding the useless deformation of the side wall bulging outwards after the cavity is inflated, ensuring that the deformation generated after the cavity is inflated is concentrated on the deformation and outward bulge of each massage part, improving the inflation utilization rate and enhancing the massage effect.

[0005] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: The massage parts are in the shape of spherical crowns with unified specifications. The topmost point of the spherical crown forms the working end of the massage part. Each massage part is evenly spaced and aligned in a row on the top wall of the cavity. The massage parts are in the shape of spherical crowns with the same specifications. After the cavity is inflated, the top ends of each spherical crown serve as the working ends of the massage to bulge upwards, transmitting massage stimulation. All the spherical crown-shaped massage parts on the top wall of the cavity are neatly arranged in a row, and the corresponding massage working ends are arranged to form a massage area with evenly spaced intervals.

[0006] Preferably, the spherical cap is formed by welding an elastic arc-shaped piece after opening a hole in the top wall of the sac cavity. A second welding edge that is continuously sealed in a circle along the circumference is formed between the entire circumference of the arc-shaped piece and the inner edge of the opening. The spherical cap corresponding to the massage part is formed by welding an elastic arc-shaped piece after opening a hole in the top wall of the sac cavity. A second welding edge that is continuous and sealed in a circle along the circumference is formed between the entire circumference of the arc-shaped piece and the inner edge of the opening. After the sac cavity is inflated, the arc-shaped piece is pushed up to cause elastic deformation, bulging upward to transmit massage stimulation.

[0007] Preferably, the bottom diameter of the spherical cap is 35 - 45 mm, and the height of the spherical cap is 4 - 7 mm. Setting the spherical cap shape of the massage part within this range of bottom diameter and height can meet the massage requirements. An overly large spherical cap diameter and height will increase the production difficulty and cost, while an overly small spherical cap diameter and height will result in poor massage stimulation effects.

[0008] Preferably, the number of the massage parts is 6 - 10. Setting the number of massage parts within this range on the top wall of the sac cavity can meet the length requirements of the massage area for the mattress or the pillow.

[0009] Preferably, the shaping structure includes at least one pulling piece in the sac cavity that horizontally pulls the two long side walls of the sac cavity. The two long side edges of the pulling piece and the corresponding long side walls of the sac cavity are connected by a third welding edge, and the third welding edge extends along the length direction of the connected sac cavity side wall. Since the pulling piece is welded to the two long side walls of the sac cavity, the pulling piece uses its elasticity to pull the two long side walls of the sac cavity to shape the sac cavity, preventing the two long side walls from bulging out horizontally when the sac cavity is inflated, thereby shaping the sac cavity.

[0010] Preferably, the two ends of the pulling piece and the side walls at the two ends of the sac cavity are connected by a fourth welding edge, and the fourth welding edge extends along the length direction of the connected sac cavity side wall. The two ends of the pulling piece are also connected to the corresponding side walls at the ends of the sac cavity by a fourth welding edge to pull the side walls at the two ends of the sac cavity, further shaping the sac cavity so that the sac cavity maintains its original shape when inflated, and only the positions of the massage parts bulge out.

[0011] Preferably, the length of the third welding edge is shorter than the length of the corresponding sac cavity side wall, and the length of the fourth welding edge is shorter than the length of the corresponding sac cavity side wall. The lengths of both the third welding edge and the fourth welding edge are shorter than the lengths of the connected sac cavity side walls. The purpose is to prevent the pulling piece from being continuously welded along the circumference to the inner wall of the sac cavity to form a seal, resulting in the complete separation and non-connection of the sac cavities on both sides of the pulling piece. The air filled from the air nozzle cannot fill all the sac cavities on both sides of the pulling piece, thereby causing the massage parts to be unable to bulge upward. When both the third welding edge and the fourth welding edge are shorter than the lengths of the sac cavity side walls where they are located, gaps can be left between the pulling piece and the sac cavity side walls along the circumference, enabling the sac cavities on both sides of the pulling piece to communicate with each other, and the air nozzle can fill the entire sac cavity with air.

[0012] Preferably, there are two pull tabs, which are vertically distributed in the airbag cavity and hold the long side walls on both sides of the airbag cavity. The air outlet of the air nozzle on the inner wall of the airbag cavity is located between the two pull tabs. There are two pull tabs, which are vertically arranged in the airbag cavity, jointly holding the side wall of the airbag cavity to shape the airbag cavity. When inflated, only the massage part bulges upward. When the air outlet of the air nozzle on the inner wall of the airbag cavity is between the two pull tabs, when inflated, the air uniformly diffuses from the airbag cavity between the two pull tabs to the remaining airbag cavities on both sides of the pull tabs, filling the airbag cavity.

[0013] The second object of the invention of the present utility model is to provide a mattress, which is provided with massage airbags inside, and is characterized in that the massage airbags are the airbags with a massage layer as described in any one of the foregoing. By using the airbag with a massage layer as described above, only the massage part effectively bulges after the airbag is inflated, so that the mattress has high inflation utilization rate and stronger massage effect.

[0014] The beneficial technical effects of the present utility model: The spherical crown-shaped protrusion specially provided on the top wall is used as the working massage part, and a shaping structure is arranged in the airbag cavity to shape the airbag body, avoiding useless deformation of the airbag body without massage effect during inflation, concentrating the deformation generated by inflating the airbag cavity on the outward convex deformation of each massage part, improving the inflation utilization rate and enhancing the massage effect.

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figures 1 to 5 As shown, embodiment 1 is an airbag with a massage layer, comprising a transversely extending bag cavity 1, an air nozzle 2 is arranged on the side of the bag cavity 1, and a plurality of massage parts 3 are formed on the top wall 1-1 of the bag cavity 1 along the length direction. The number of the massage parts 3 is 6 to 10. As shown in the figure, the present embodiment preferably has 8 massage parts aligned in a row, and each massage part 3 can bulge upward after the bag cavity 1 is inflated to form an upwardly transmitted massage stimulation. A shaping structure is arranged in the bag cavity 1 to hold the side wall of the bag cavity 1 when the bag cavity 1 is inflated to prevent the bag cavity 1 from bulging outward laterally and causing useless deformation without massage effect.

[0025] like Figure 6 and Figure 7 As shown, the capsule 1 is composed of a foldable sheet 9 with four folding sections and two flat sheets 10. The sheet 9 and the flat sheets 10 are both made of transparent TPU. The sheet 9 is curled and connected to form a first welding edge 11. Figure 7 The shown cylindrical body is open at both ends, and the four folded sections respectively form the four faces of the cylindrical body, and the four faces form the two long side walls 1-2 on both sides of the bag cavity 1 and the top wall 1-1 and the bottom wall of the bag cavity 1. The bottom wall of the bag cavity 1 is provided with a fixing ear 12 for installing the airbag, and two flat sheets 10 are respectively connected to the two ends of the cylindrical body through the fifth welding edge 13 to seal the opening and form the side walls at both ends of the bag cavity 1, and the air nozzle 2 is arranged on one of the flat sheets 10.

[0026] During operation, the bag cavity is inflated through the air nozzle, and the top wall where the eight massage parts on the top of the bag cavity are located bulges upward, forming a massage stimulation transmitted upward. Compared with the existing airbag that bulges outward as a whole, the specially arranged row of massage positions is more precise and the massage effect is more prominent. At the same time, the side walls of the bag cavity are pulled by the shaping structure inside the bag cavity to shape the bag cavity. In this embodiment, the other wall surfaces around the bag cavity except the top wall and the bottom wall maintain their original vertical shape and do not bulge outward laterally, avoiding useless deformation of bulging outward after inflation, ensuring that the deformation generated after the bag cavity is inflated is concentrated on the positions of each massage part, improving the utilization efficiency of inflation, and enhancing the massage effect.

[0027] Further, as shown in the figure, the massage part 3 is in the shape of a uniform spherical cap, the top of the highest point of the spherical cap forms the working end 3-1 of the massage part 3, and each massage part 3 is evenly spaced and aligned in a row on the top wall 1-1 of the capsule cavity 1, and when working, all massage working ends form a massage area with even spacing. The bottom diameter D of the spherical cap is 35-45 mm, and the height H of the spherical cap is 4-7 mm. The setting value of the spherical cap shape can meet the massage work requirements of the airbag.

[0028] The spherical cap is formed by opening a hole 1-3 in the top wall 1-1 of the cavity 1 and welding an elastic arc-shaped piece 4. The arc-shaped piece is also made of TPU material. A second welding edge 5 that is continuously sealed in a circle along the circumference is formed between the outer circumference of the arc-shaped piece 4 and the inner edge of the hole in the top wall of the cavity. When the cavity is inflated, the arc-shaped piece is lifted up to cause elastic deformation, bulging upwards to transmit massage stimulation.

[0029] Furthermore, the shaping structure includes at least one pulling piece 6 in the cavity 1 that horizontally pulls the two long side walls 1-2 of the cavity 1. In this embodiment, it is preferably two parallel pulling pieces 6 distributed up and down. The cavity is pulled by the combined action of the two pulling pieces to shape the cavity when inflated. The two long side edges of each pulling piece 6 are connected to the corresponding long side wall 1-2 of the cavity 1 through a third welding edge 7. The third welding edge 7 extends along the length direction of the side wall of the connected cavity 1. At the same time, both ends of the pulling piece 6 are connected to the side walls at both ends of the cavity 1 through a fourth welding edge 8. The fourth welding edge 8 extends along the length direction of the side wall of the connected cavity 1. The length of the third welding edge 7 is shorter than the length of the corresponding side wall of the cavity 1, and the length of the fourth welding edge 8 is also shorter than the length of the corresponding side wall of the cavity 1. Since both the third welding edge and the fourth welding edge are shorter than the length of the side wall of the cavity where they are located, gaps can be left between the pulling piece and the inner wall of the cavity along the circumference. Furthermore, the cavities on both sides of the pulling piece can communicate with each other, and the air nozzle can inflate the entire cavity. The air outlet of the air nozzle 2 on the inner wall of the cavity 1 is located between the two pulling pieces 6 to quickly and evenly inflate the cavity.

[0030] Embodiment 2 is a mattress with massage airbags inside. The massage airbags are the airbags with a massage layer described in Embodiment 1. By using the airbags with a massage layer mentioned above, only the massage part bulges out usefully after inflation. The utilization efficiency of the mattress inflation is high, and the massage effect is good.
