Detailed Implementation

[0034] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0035] Example:

[0036] Key reference Figure 1-13 The device mainly includes a silicone airbag 403, a sealing inner plate 404, a sealing base plate 402, a connecting tee 501, and a connecting elbow vent pipe 601.

[0037] The airbags used in the mattress are mainly made of TPU material. TPU airbags are composed of sheet-like or stacked sheet-like structures. The production cost of TPU material is relatively high. In order to save costs and facilitate subsequent maintenance, this technical solution was designed.

[0038] like Figure 1-3 As shown, the device can be composed of a single silicone airbag 403 or multiple silicone airbags 403.

[0039] The silicone airbag 403 has frame-shaped airbag sealing ribs 4031 (preferably integrally formed) on both the inner and outer sides of its bottom. The silicone airbag 403 has an inner sealing plate 404 at its bottom, with sealing grooves 4041 around its bottom perimeter. These grooves engage with the outer wall of the inner airbag sealing ribs 4031, allowing the inner sealing plate 404 and the airbag sealing ribs 4031 to be positioned together. A sealing base plate 402 is placed at the bottom of the silicone airbag 403, with base plate grooves 4021 around its top perimeter. These grooves engage with the outer airbag sealing ribs 4031.

[0040] The sealing base plate 402, the silicone airbag 403, and the airbag sealing rib 4031 are all provided with round holes. The sealing inner plate 404 is provided with a threaded groove. The fixing screw 401 passes through the round holes of the sealing base plate 402, the airbag sealing rib 4031, and the sealing base plate 402 and is threaded into the threaded groove of the sealing inner plate 404, so that the silicone airbag 403, the sealing inner plate 404, and the sealing base plate 402 are sealed together. The fixing screw 401 passes through the groove 4021 of the base plate and the groove 4041 of the sealing inner plate. The above constructs a sealed airbag, and the bottom of the airbag has a flat plate, so that the airbag is pushed upward when inflated to form a mattress.

[0041] Different inflation connector connection methods are designed based on different combinations of different numbers of silicone airbags 403. Note that each silicone airbag 403 is provided with an airbag vent 5042, and the inflation connector is used for inflation or deflation through the airbag vent 5042.

[0042] For example, a single silicone airbag 403 is connected to a bend-type air pipe 601 that passes through the airbag's air vent 5042.

[0043] The outer walls of the two side connectors of the elbow vent pipe 601 are fixedly connected with first retaining rings 505. The first retaining rings 505 have first auxiliary grooves 5011 that mate with the sealing ribs 5041 of the silicone air bladder vent holes. The outer walls of the two side connectors of the elbow vent pipe 601 are provided with first external threads 5012. A first sealing gasket 502 is fitted onto the outer wall of the first external thread 5012. The first sealing gasket 502 has sealing gasket grooves 5021 that mate with the sealing ribs 5041 of the silicone air bladder vent holes. First plastic locking nuts 503 are threadedly connected to the first external threads 5012 of the two side connectors of the elbow vent pipe 601, ensuring that the two side connectors of the elbow vent pipe 601 are stably installed at the air bladder vent holes 5042 of the two silicone air bladders 403. By inflating the elbow vent pipe 601, the silicone air bladders 403 form a mattress. To make the device easier to use, a valve or plug is installed at one end of the connecting elbow vent pipe 601 to ensure that the silicone airbag 403 remains stable after forming a mattress.

[0044] Multiple silicone airbags 403 are designed as a combination, with a connecting tee 501 passing through the airbag vent 5042. A silicone airbag vent sealing rib 5041 is provided on the outside of the airbag vent 5042. A first retaining ring 505 is fixedly connected to the outer wall of the two connectors of the connecting tee 501. A first auxiliary groove 5011 is provided on the first retaining ring 505 to cooperate with the silicone airbag vent sealing rib 5041. A first external thread 5012 is provided on the outer wall of the two connectors of the connecting tee 501. A first sealing gasket 502 is fitted on the outer wall of the first external thread 5012. A first plastic locking nut 503 is threadedly connected to the first external thread 5012 of the two connectors of the connecting tee 501. The locking of the first plastic locking nut 503 and the cooperation of the first retaining ring 505 and the first sealing gasket 502 make the two connectors of the connecting tee 501 stably installed at the airbag vent 5042 of the two silicone airbags 403. To make the device easier to use, a valve or plug is installed at the third connector of the tee 501 to ensure that the silicone airbag 403 remains stable after forming the mattress.

[0045] An airbag support block 604 is provided inside the silicone airbag 403. The airbag support block can be made of sponge or non-adhesive cotton, or other compressible and resilient materials, and is used to support the airbag in its initial state.

[0046] When multiple airbags need to be arranged in a combination, there are four sealing inner plate fixing posts 701 on the sealing base plate 402. Each sealing inner plate fixing post 701 has a sealing inner plate fixing post groove 7011 near its outer head. Then, the airbag elastic connecting bracket 7021 on the airbag elastic connecting bracket 702, with four airbag elastic connecting bracket connecting holes 7021 at its four corners, fits into the sealing inner plate fixing post groove 7011 on the sealing inner plate fixing post 701. Figure 8 As shown in the right figure, the remaining three airbag elastic connecting bracket connecting holes 7021 are then connected to the adjacent sealing inner plate fixing column 701 in sequence. The number of arrangements is determined according to actual needs. By different air tube connection methods and the control of the program, a series of customer-required dimensions such as strip-shaped action or point-shaped action can be achieved.

[0047] In practice, first determine the required mattress shape and size, and then determine the number of silicone air bladders 403 to be selected. Determine the connection method for the air tubes. When selecting a single silicone air bladder 403, use a connecting elbow air tube 601 to connect the air bladder vent 5042. When selecting multiple silicone air bladders 403, use a connecting tee 501 to connect the air bladder vent 5042. For a special number of silicone air bladders 403, the connecting elbow air tube 601 or connecting tee 501 should be fixedly installed at the air vent 5042 of the silicone air bladders 403, depending on the actual situation.

[0048] In order to ensure that multiple silicone airbags 403 can be stably installed together and form the required shape, 702 is used to fix adjacent sealing base plates 402 together.

[0049] When ventilation is needed, use an air pump to inflate the connecting tee 501 or the connecting elbow vent pipe 601. When the silicone airbag 403 reaches the preset inflated state, stop inflating and keep the silicone airbag 403 in a stable mattress posture by closing the valve or plug.

[0050] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
