Description

Technical Field

[0001] The utility model relates to the field of bedding, and particularly to an airbag pad and a mattress using the same. Background Art

[0002] An existing mattress is provided with an airbag pad with adjustable air pressure. The airbag pad includes airbag strips arranged closely in the front-back direction. The airbag pad of any size is formed by splicing the airbag strips, which is convenient for filling and using in the mattress. Three-way pipe fittings are provided on each airbag strip, which not only ensure that adjacent airbag strips can be connected through the three-way pipe fittings, so that the air pressure in multiple airbag strips is kept balanced, but also ensure that the airbag strips can be connected to an external controller to adjust the air pressure, achieving the purpose of softness and hardness adjustment. The airbag pad includes a main channel that is laterally arranged and connects all the three-way pipe fittings in series and an air path channel arranged in each airbag strip. The existing three-way pipe fittings are all horizontally arranged, resulting in the main channel being exposed outside the edge of the airbag strip. When a user sits on the edge of the airbag pad, the main channel is easily squeezed and deformed due to being exposed, resulting in unsmooth air flow transportation in the main channel, affecting the air pressure adjustment speed and accuracy in the airbag pad and the use experience. Summary of the Utility Model

[0003] In order to solve the deficiencies of the existing technology, the utility model provides an airbag pad and a mattress using the same, which vertically arrange the three-way pipe fittings, and the vertical projections of the upper pipe orifice and the lower pipe orifice are both located inside the airbag strip. The airbag strip is used to support the user and prevent the main channel from being pressed and sunken, ensuring smooth air flow and improving the use experience.

[0004] The utility model is realized in the following way: An airbag pad includes airbag strips arranged closely in the front-back direction. An air path channel is provided on the airbag strip. An upwardly open air orifice is provided at the end of the air path channel. A T-shaped three-way pipe fitting is provided on the air orifice. The three-way pipe fitting includes a lower pipe orifice communicated with the air orifice and upper pipe orifices that are separated front and back. The corresponding upper pipe orifices of adjacent three-way pipe fittings are hermetically connected through a sleeve. By vertically arranging the three-way pipe fittings, the lower pipe orifice can be connected to the air orifice of the corresponding airbag strip, and the upper pipe orifice is used for connecting adjacent three-way pipe fittings. The vertical projections of the upper pipe orifice and the lower pipe orifice are both located inside the airbag strip. The airbag strip is used to support the user and prevent the main channel from being pressed and sunken, ensuring smooth air flow and improving the use experience.

[0005] Preferably, a patch is formed by extending outward at the port of the lower pipe orifice. The patch is welded and adhered to the periphery of the air orifice so that the lower pipe orifice is aligned and communicated with the air orifice. The patch is formed by extending outward from the periphery of the port of the lower pipe orifice. When the lower pipe orifice is aligned with the air orifice, the patch closely adheres to and is welded and adhered to the peripheral area of the air orifice, ensuring sealed communication between the air orifice and the lower pipe orifice. It not only effectively prevents air leakage, but also plays a role in limiting and preventing the three-way pipe fitting from tipping over, ensuring that the three-way pipe fitting maintains a vertical posture.

[0006] Preferably, the patch is closely attached to the peripheral region of the air port through deformation. The peripheral region of the air port is non-planar. The patch is closely attached to the peripheral region of the air port through deformation, and the sealing effect is improved by increasing the attachment area.

[0007] Preferably, the patch is inserted into the air passage and adhesively attached to the inner wall of the air passage at the peripheral region of the air port. After the patch passes through the air port and is inserted into the air passage, it is closely attached to the inner wall of the air passage at the peripheral region of the air port through its top surface. This not only effectively prevents the patch from detaching from the air passage and improves the anti-pulling performance between the tee pipe fitting and the air passage, but also enhances the sealing reliability and prevents air leakage.

[0008] Preferably, a radially opened incision is provided at the periphery of the air port. The incision is opened to increase the area of the air port for the tee pipe fitting to pass through. By opening the incision to expand the area of the air port, it is convenient for the patch to pass through the air port and be inserted into the air passage, facilitating assembly.

[0009] Preferably, the incision is completely covered by the patch so that the lower pipe orifice is in sealed communication with the air passage. The incision can be switched between open and closed states to facilitate the patch to pass through the air port. After the patch is installed in place, it can completely cover the incision, which not only ensures that both the incision and the air port can be effectively sealed by the patch, but also prevents the patch from detaching from the air passage.

[0010] Preferably, the incision is cross-shaped and concentric with the air port. This not only ensures that the patch can easily pass through after the incision is opened, but also facilitates the incision to fit with the patch after it is closed, ensuring the sealed connection between the air port and the tee pipe fitting.

[0011] Preferably, the airbag strip includes a long strip-shaped air passage platform and unit airbags linearly arranged along the length direction of the air passage platform. The air passage is provided on the air passage platform and is in communication with each unit airbag along the way. The air passage platform is not only used to fixedly connect the unit airbags to ensure the relative positions of the unit airbags are fixed, but also used to lay the air passage and connect each unit airbag in series to ensure that the air pressures in each unit airbag are kept constant and can be adjusted synchronously. Moreover, the front edge and the rear edge of the air passage platform can be used to realize the overlapping and welding fixation between adjacent airbag strips.

[0012] Preferably, the air passage platform includes an upper sheet and a lower sheet. The upper sheet and the lower sheet are vertically stacked and enclose the air passage through local welding. The upper sheet and the lower sheet are independently processed and stacked and adhered to form an air passage platform with an air passage. This not only facilitates the installation of the tee pipe fitting before forming the air passage platform, but also facilitates the stacked assembly and improves the assembly efficiency.

[0013] Preferably, the inner diameter of the sleeve is the same as the outer diameter of the upper pipe opening. The sleeve port is sleeved on the upper pipe opening and sealed and connected through circumferential welding. The sleeve port is tightly sleeved on the upper pipe opening and welded and sealed, which is convenient for processing and ensures the sealed connection between the corresponding upper pipe openings through the sleeve.

[0014] A mattress using the airbag pad includes a pad body, and the pad body includes an airbag pad and a limiting block that clamps and wraps the airbag pad. The limiting block plays a role in clamping, positioning and protecting the airbag pad, ensuring that the airbag pad is adjusted in hardness by inflating and deflating at a preset position, thereby improving the comfort of using the pad body.

[0015] The beneficial effects of the present utility model: The three-way pipe fitting is arranged vertically. The lower pipe opening can be connected to the air port of the corresponding airbag strip, and the upper pipe opening is used for connecting adjacent three-way pipe fittings. The vertical projections of the upper pipe opening and the lower pipe opening are both located within the airbag strip. The airbag strip is used to support the user and prevent the main channel from being indented, ensuring smooth air passage and improving the use experience. Description of the Drawings

[0022] The following further illustrates the substantial features of the present utility model in conjunction with the drawings of the specification and specific embodiments.

[0023] Embodiment 1:

[0024] This embodiment provides an airbag pad.

[0025] As Figure 1 , 2An airbag cushion as shown in FIGS. 2 and 3 includes airbag strips 1 arranged closely in the front-to-back direction. An air passage channel 2 is provided on the airbag strip 1. An air port 3 that is open upward is provided at the end of the air passage channel 2. A T-shaped three-way pipe fitting 4 is provided on the air port 3. The three-way pipe fitting 4 includes a lower pipe orifice 5 that communicates with the air port 3 and upper pipe orifices 6 that are arranged back-to-back in the front and rear. The corresponding upper pipe orifices 6 of adjacent three-way pipe fittings 4 are hermetically connected through a sleeve 7. When the three-way pipe fitting 4 is arranged vertically, the lower pipe orifice 5 can be connected to the air port 3 of the corresponding airbag strip 1, and the upper pipe orifice 6 is used for connecting adjacent three-way pipe fittings 4. The vertical projections of the upper pipe orifice 6 and the lower pipe orifice 5 are both located within the airbag strip 1. The airbag strip 1 is used to support the user and prevent the main channel from being pressed and deformed, ensuring smooth air passage and improving the user experience.

[0026] In this embodiment, the three-way pipe fitting 4 is arranged vertically, so that the projection of the three-way pipe fitting 4 completely falls within the airbag strip 1 and is close to the unit airbag 11. When the user sits on the edge of the airbag cushion 12, the user will be supported by the unit airbag 11, effectively preventing the main channel from being pressed and deformed due to the user's sitting pressure, ensuring smooth air passage.

[0027] In this embodiment, a patch 8 is formed by extending outward at the port of the lower pipe orifice 5. The patch 8 is welded and adhered to the periphery of the air port 3 so that the lower pipe orifice 5 is aligned and communicated with the air port 3. The patch 8 and the lower pipe orifice 5 are integrally processed. The periphery of the lower pipe orifice 5 forms the patch 8 by extending radially outward, ensuring a sealed connection between the patch 8 and the periphery of the lower pipe orifice 5.

[0028] In this embodiment, the air passage platform 10 includes an upper sheet and a lower sheet. The air port 3 is opened on the upper sheet. An openable cut 9 is provided on the periphery of the air port 3. During assembly, first, the lower pipe orifice 5 of the three-way pipe fitting 4 penetrates the air port 3 from top to bottom. The patch 8 is deformed under pressure and contracts towards the axis of the air port 3. The cut 9 will be opened by the pushing of the patch 8 and the air port 3 will be enlarged, so that the contracted patch 8 can pass through the opened cut 9 under the drive of the lower pipe orifice 5 and be exposed below the upper sheet. Then, the patch 8 returns to its original shape and fits with the bottom surface of the upper sheet in the area around the air port 3. The patch 8 and the bottom surface of the upper sheet are overlapped and welded and fixed. The patch 8 covers the cut 9, so that the lower pipe orifice 5 is hermetically connected to the air port 3. Finally, the upper sheet and the lower sheet are vertically overlapped and locally welded to enclose the air passage channel 2. The upper sheet and the lower sheet are overlapped, and a welding area is provided along the periphery of the air passage channel 2, so that the upper sheet and the lower sheet are welded and fixed and enclosed to form an air passage channel 2 that meets the air flow transportation requirements.

[0029] In this embodiment, the patch 8 is closely attached to the peripheral region of the air port 3 through deformation, and the patch 8 is inserted into the air passage 2 and adhered to the inner wall of the air passage 2 in the peripheral region of the air port 3. The upper patch and the lower patch form a groove strip through deformation. After the upper patch and the lower patch are stacked, the air passage 2 is formed by enclosing with the groove strip. Since the bottom wall of the groove strip is non-planar, the peripheral region of the air port 3 is also non-planar. The patch 8 matches and adheres to the peripheral region of the air port 3 through its own deformation, thereby ensuring that the peripheral region of the air port 3 is continuously welded circumferentially, and further ensuring the sealing reliability.

[0030] In this embodiment, a radially opened cut 9 is provided on the periphery of the air port 3. The cut 9 is opened to increase the area of the air port 3 for the three-way pipe fitting 4 to pass through. The cut 9 is provided on the periphery of the air port 3 to ensure that the cross-sectional area of the air port 3 can be increased after the cut 9 is opened, thereby facilitating the patch 8 to pass through the air port 3 and adhere and fix to the inner wall of the air passage 2. During installation, the cut 9 is completely covered by the patch 8, and the cut 9 and the peripheral region of the air port 3 are both adhered and welded, preventing the gas in the air passage 2 from leaking out through the cut 9 or the air port 3, ensuring that the cut 9 is always in a closed state, improving the sealing reliability, and ensuring the sealed connection between the lower pipe orifice 5 and the air passage 2.

[0031] In this embodiment, the cut 9 is cross-shaped and concentrically arranged with the air port 3, which is convenient for the opening and closing deformation of the cut 9 and also convenient for the cut 9 to be covered and blocked by the patch 8, improving the sealing reliability. In addition, the cut 9 can also be linear, which should also be regarded as a specific implementation manner of this embodiment.

[0032] In this embodiment, the inner diameter of the sleeve 7 is the same as the outer diameter of the upper pipe orifice 6. The port of the sleeve 7 is sleeved on the upper pipe orifice 6 and sealed and connected through circumferential welding. The two ports of the sleeve 7 are sleeved on the corresponding upper pipe orifices 6 to make the corresponding upper pipe orifices 6 of adjacent three-way pipe fittings 4 be sealed and connected, thereby ensuring the connection between adjacent three-way pipe fittings 4.

[0033] In this embodiment, the airbag strip 1 includes a plurality of unit airbags 11 arranged linearly (such as Figure 4As shown in the figure, the unit air sacs 11 are connected by an air passage 2 laid along the length direction of the air sac strip 1, and the end of the air passage 2 extends outward to form the three-way pipe fitting 4. The unit air sacs 11 are arranged at equal intervals in a straight line, ensuring that the distance between the unit air sacs 11 is the same, thereby facilitating the formation of an air sac pad 12 with matrix-shaped unit air sacs 11 by splicing the air sac strips 1, which not only improves the use comfort but also facilitates assembly. The adjacent unit air sacs 11 are connected by the air passage 2, so that the air pressure in each unit air sac 11 on the same air sac strip 1 can be synchronously adjusted. The adjacent air sac strips 1 are communicated through the adjacent three-way pipe fittings 4, so that the air pressure in the adjacent air sac strips 1 can be synchronously adjusted. By connecting the air sac strips 1 in each partition on the air sac pad 12 in series, the air pressure in the air sac strips 1 in each partition can be synchronously adjusted, which not only simplifies the air path structure but also facilitates precise control and use.

[0034] Embodiment 2:

[0035] Compared with Embodiment 1, this embodiment provides a mattress.

[0036] As Figure 5 shown in the figure, the mattress includes a mattress body, and the mattress body includes an air sac pad 12 and a limiting block 13 that clamps and wraps the air sac pad 12. The limiting block 13 plays a role in clamping, positioning and protecting the air sac pad 12, ensuring that the air sac pad 12 is adjusted in softness and hardness by inflating and deflating at a preset position, thereby improving the use comfort of the mattress body.

[0037] In this embodiment, the limiting block 13 is provided with through holes, and the number and positions of the through holes are in one-to-one correspondence with the unit air sacs 11 on the air sac pad 12. During installation, the limiting block 13 wraps the air sac pad 12, and the through holes are sleeved on the corresponding unit air sacs 11, so that each unit air sac 11 is limited by the inner wall of the through hole, ensuring that the unit air sacs 11 realize vertical expansion and contraction under the guidance of the through holes, and further adjusting the softness and hardness by adjusting the air pressure to provide comfortable support for the user.

[0038] The other structures and effects of the air sac pad in this embodiment are the same as those in Embodiment 1 and will not be repeated.
