[0022] See also Figure 1 , Figures 5 to 8A combined low-noise valve body structure includes a first valve body 100 and a second valve body 200. One end of the first valve body 100 is provided with a diverter nozzle 300 and an air nozzle 400, and the other end is a combined end 500. The diverter nozzle 300 includes an air inlet end 310 and a diverter end 320. Between multiple first valve bodies 100, the air inlet end 310 of the rear first valve body 100 can be inserted into the diverter end 320 of the front first valve body 100; the second valve body 200 is provided with a combined groove 600 and an exhaust opening 700. The combined end 500 of the first valve body 100 can be inserted into the combined groove 600 of the second valve body 200, so that the first valve body 100 is connected to the second valve body 200, and the exhaust opening 700 of the second valve body 200 is provided with sound-absorbing cotton 800.

[0023] Specifically, in this embodiment, the first valve body 100 is an inflation valve (massage valve), the second valve body 200 is an air release valve, a diverter nozzle 300 and an air nozzle 400 are arranged at the top end of the first valve body 100, wherein the air nozzle 400 is connected to the air bag, and the diverter nozzle 300 includes an air inlet end 310 and a diverter end 320, and the bottom end of the first valve body 100 forms a combination end 500, and at the same time, a combination groove 600 is arranged at the top end of the second valve body 200. When combining, the combination end 500 of the first valve body 100 is directly inserted into the combination groove 600 of the second valve body 200, so that the first valve body 100 and the second valve body 200 can be combined, and the latter first valve body 100 can be connected to the second valve body 200. The air inlet end 310 of the valve body 100 is inserted into the diverter end 320 of the previous first valve body 100, so as to realize the combination of multiple first valve bodies 100. Of course, a single first valve body 100 can be combined with a single second valve body 200 to form a combination, and then a single or multiple first valve bodies 100 can be combined with the combination. Multiple combinations can also be combined to realize the combination of multiple first valve bodies 100 and a single or multiple second valve bodies 200. Multiple first valve bodies 100 can also be combined with multiple corresponding second valve bodies 200. Finally, the valve body structures can be converted to each other and combined arbitrarily to meet user needs.

[0024] In addition, when the airbag needs to be deflated, the second valve body 200 can be opened, and the gas can be discharged outward from the exhaust opening 700 of the second valve body 200. At the same time, sound-absorbing cotton 800 is installed at the exhaust opening 700. The sound-absorbing cotton 800 can effectively reduce the noise during exhaust, thereby improving the problem of loud exhaust noise.

[0025] See also Figure 2 and Figure 4In the present embodiment, the first valve body 100 is an inflation valve, i.e., a massage valve. In order to realize the normal operation of the first valve body 100, the first valve body 100 includes a first coil frame 110, a first movable iron core 120, a first fixed iron core 130 and a first iron frame 140. The diverter nozzle 300 and the air nozzle 400 are respectively arranged on the first coil frame 110 and communicated with the interior of the first coil frame 110. A first coil 150 is wound around the outer wall of the first coil frame 110. The first movable iron core 120 is arranged in the first coil frame 110. One end of the first fixed iron core 130 is inserted into the first coil frame 110, and the other end protrudes outward to form a combined end 500. The first fixed iron core 130 is provided with an air venting hole 131 communicated with the interior of the first coil frame 110. A first spring 160 is arranged between the first movable iron core 120 and the first fixed iron core 130. The first iron frame 140 is clamped on the first coil frame 110 and clamps the first fixed iron core 130.

[0026] When the first valve body 100 is used alone, the air bag is connected to the air nozzle 400, and the first coil 150 is energized to generate a magnetic field. At this time, the first fixed iron core 130 and the first movable iron core 120 are magnetized, and the first movable iron core 120 moves in the first coil frame 110 through the magnetic attraction principle, compressing the first spring 160 and magnetically attracting the first fixed iron core 130 to block the air leakage hole 131 of the first fixed core 130, and the air nozzle 400 is closed. 00 and the diverter nozzle 300 are respectively connected to the interior of the first coil frame 110, and the gas enters the first coil frame 110 from the air inlet end 310 of the diverter nozzle 300, and then enters the air nozzle 400 from the interior of the first coil frame 110, and passes through the air nozzle 400 to the air bag to inflate the air bag. When multiple first valve bodies 100 are combined, the gas at the air inlet end 310 can enter the next first valve body 100 from the diverter end 320 to inflate other air bags.

[0027] When the power to the first coil 150 is cut off and the magnetic field disappears, the first movable iron core 120 is reset under the action of the rebound force of the first spring 160, and the inside of the first coil frame 110, the diverter nozzle 300 and the air nozzle 400 are blocked and closed, while the air leakage hole 131 of the first fixed iron core 130 is opened, and the gas in the air bag flows back into the first coil frame 110 and is discharged outward along the inside of the first coil frame 110 toward the air leakage hole 131 of the first fixed iron core 130. The massage function can be achieved by repeated cycles.

[0028] In order to achieve the sealing of the first coil frame 110 and the air leakage hole 131, a first slot 121 is respectively provided at both ends of the first movable iron core 120, and a first stopper 122 is clamped in the first slot 121. The first stopper 122 is arranged in the first slot 121 in a clamping manner, which can change the existing bonding method, so that the first stopper 122 and the first slot 121 are easy to install, and the risk of falling off caused by the bonding method in the prior art can be avoided.

[0029] At the same time, in order to prevent the first movable iron core 120 from directly hitting the first coil frame 110 and the first fixed iron core 130, after the first stop plate 122 is installed in the first slot 121, the first stop plate 122 will protrude from the first slot 121. Through its protruding part, the first movable iron core 120 can be prevented from directly hitting the first coil frame 110 and the first fixed iron core 130, thereby effectively reducing the impact sound and reducing noise.

[0030] In addition, in order to better combine multiple first valve bodies 100 and between the first valve body 100 and the second valve body 200, in this embodiment, a first sealing ring 170 is sleeved on the end of the first fixed iron core 130 inserted into the first coil frame 110, a second sealing ring 180 is sleeved on the end protruding outward, and a third sealing ring 190 is sleeved on the air inlet end 310 of the diverter nozzle 300.

[0031] When the first valve body 100 is combined with the second valve body 200, the combination end 500 formed by the protruding outward of the first fixed iron core 130 can be directly inserted into the combination groove 600 of the second valve body 200, and a tight fit and sealing can be achieved through the second sealing ring 180, and the first fixed iron core 130 is inserted into the first sealing ring 170 sleeved in the first coil frame 110, which can effectively seal the inside of the first coil frame 110; when multiple first valve bodies 100 are combined, the air inlet end 310 of the diverter nozzle 300 of the rear first valve body 100 is inserted into the diverter end 320 of the diverter nozzle 300 of the front first valve body 100, and the two first valve bodies 100 can be tightly matched and sealed through the third sealing ring 190. Finally, the second sealing ring 180 and the third sealing ring 190 make the combination of multiple first valve bodies 100 simple and reliable, and at the same time, the combination between the first valve body 100 and the second valve body 200 is simple and reliable.

[0032] See also Figure 3 and Figure 4In this embodiment, the second valve body 200 is a vent valve. In order to realize the exhaust function of the second valve body 200, the second valve body 200 includes a second coil frame 210, a second movable iron core 220, a second fixed iron core 230 and a second iron frame 240. The combined groove 600 and the exhaust opening 700 are respectively arranged on the second coil frame 210 and are communicated with the inside of the second coil frame 210. A second coil 250 is wound around the outer wall of the second coil frame 210. The second movable iron core 220 is arranged inside the second coil frame 210. The second fixed iron core 230 is partially inserted into the second coil frame 210. A second spring 260 is provided between the second movable iron core 220 and the second fixed iron core 230. The second iron frame 240 is clamped on the second coil frame 210 and fixes the second fixed iron core 230.

[0033] The first valve body 100 is combined with the second valve body 200, and the first coil 150 is energized to generate a magnetic field. The first fixed iron core 130 and the first movable iron core 120 are magnetized, and the first movable iron core 120 moves in the first coil frame 110 through the magnetic attraction principle, and the first spring 160 is compressed and magnetically attracted to the first fixed iron core 130 to block the air leakage hole 131 of the first fixed iron core 130, while the air nozzle 400 and the diverter nozzle 300 are respectively connected to the first coil frame 100. 0 is internally conductive, gas enters the first coil frame 110 from the gas inlet end 310 of the diverter nozzle 300, then enters the gas nozzle 400 from the first coil frame 110, and enters the air bag through the gas nozzle 400 to inflate the air bag; when the first coil 150 is powered off, the magnetic field disappears, the first movable iron core 120 is reset under the action of the rebound force of the first spring 160, and the interior of the first coil frame 110, the diverter nozzle 300 and the gas nozzle 400 are closed, and the first fixed iron core 130 is The vent hole 131 is opened, and the gas in the air bag flows back into the first coil frame 110, and flows along the inside of the first coil frame 110 toward the vent hole 131 of the first fixed iron core 130. Since the second valve body 200 is in a non-powered closed state, the gas cannot be discharged at this time, so that the pressure-maintaining lumbar support function can be achieved; when the second valve body 200 is energized, the second coil 250 generates a magnetic field, magnetizing the second fixed iron core 230 and the second movable iron core 220, and the second movable iron core 220 will be connected with the second fixed iron core 230. The fixed iron core 230 is magnetically attracted and compresses the second spring 260, so that the air leakage hole 131 of the first fixed iron core 130 is connected to the inside of the second coil frame 210. At this time, the gas flows from the air leakage hole 131 to the second coil frame 210, and is exhausted outwardly from the second coil frame 210 toward the exhaust opening 700, thereby realizing the exhaust function of the air bag, and when exhausting outward, the exhaust noise is effectively absorbed by the sound-absorbing cotton 800, thereby reducing the noise when the valve body is working.

[0034] Similarly, in order to prevent the second movable iron core 220 from directly colliding with the second coil frame 210 and the second fixed iron core 230, the second movable iron core 220 is provided with a second slot 221 at both ends thereof in the present embodiment, and a second stopper 222 is provided in the second slot 221, and the second stopper 222 protrudes from the second slot 221. The second stopper 222 and the second slot 221 are engaged with each other, so that the installation thereof can be facilitated, and the impact noise can be effectively reduced by the second stopper 222.

[0035] Finally, see Figures 5 to 8 The present invention also provides a combination method of a combined low-noise valve body structure, including the following combination methods: 1) Insert the combination end 500 of the first valve body 100 into the combination groove 600 of the second valve body 200 to form a combination of the first valve body 100 and the second valve body 200; 2) Insert the air inlet end 310 of the diverter nozzle 300 of the rear first valve body 100 into the diverter end 320 of the diverter nozzle 300 of the front first valve body 100, and so on, to form a combination of multiple first valve bodies 100; 3) Insert the combination end 500 of the first valve body 100 into the combination groove 600 of the second valve body 200, and then insert the air inlet end 310 of the diverter nozzle 300 of the rear first valve body 100 into the diverter end 320 of the diverter nozzle 300 of the front first valve body 100, so as to form a combination of multiple first valve bodies 100 and one second valve body 200; 4) Insert the combined ends 500 of the multiple first valve bodies 100 into the combined grooves 600 of the multiple corresponding second valve bodies 200, and then insert the air inlet end 310 of the diverter nozzle 300 of the rear first valve body 100 into the diverter end 320 of the diverter nozzle 300 of the front first valve body 100, and so on, to form a combination of multiple first valve bodies 100 and multiple second valve bodies 200.

Specifically, when combining, the air intake end 310 of the diverter nozzle 300 of the latter first valve body 100 can be inserted into the diverter end 320 of the diverter nozzle 300 of the former first valve body 100, and so on, so that a combination of multiple first valve bodies 100 can be realized to form a multi-point massage function; and the combination end 500 of the first valve body 100 is inserted into the combination groove 600 of the second valve body 200, so that the combination of the first valve body 100 and the second valve body 200 can be realized to form a lumbar support valve and realize the pressure holding function; the first valve body 100 and the second valve body 200 can also be combined to form a lumbar support valve, and then another first valve body 100 and the lumbar support valve can be combined. The first valve body 100 can be combined with the second valve body 200, and so on, so that multi-point lumbar support can be realized; the first valve body 100 can be combined with the second valve body 200 to form a lumbar support valve, and so on, multiple lumbar support valves can be combined, and then the first valve bodies 100 in the multiple lumbar support valves can be combined with each other, so as to realize multi-point multi-massage lumbar support, and finally, through the air inlet end 310 and the diverter end 320 of the diverter nozzle 300, and the combination end 500 and the combination groove 600, the mutual conversion and arbitrary combination of the first valve body 100 and the second valve body 200 can be realized, so as to meet the lumbar support massage needs of various numbers of points of different customers, and it is more convenient and saves more mold costs than the pipeline connection or multiple sets of mold combination methods on the market, and at the same time, the sealing is more reliable.
