Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0089] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0090] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

The cross-section of the first inflation channel 140 is circular, and only the first space 111 is connected to the first inflation channel 140 through the first inflation port 112. Only the first inflation chamber 110 is connected to the gas-using device through the first air outlet 113, and the top of the first air release chamber 120 is sealed. Gas from the gas-using devices corresponding to the two first air distribution groups can be discharged through the first air release channel 123 located between the two corresponding first air release ports 122.

[0104] In some embodiments, the first air distribution group includes two air distribution components distributed along the second direction, and the two first inflation chambers 110 of the same air distribution group are adjacent to each other, and the first deflation chamber 120 is located on the side of the corresponding first inflation chamber 110 away from the other group of air distribution components.

[0105] Please refer to Figure 3. The four first inflation chambers 110 are all located in the middle, and the four first deflation chambers 120 are all located at the ends. The air distribution mechanism includes two first deflation channels 123 located at the ends. Since only the first inflation chamber 110 is connected to the first inflation channel 130 through the first inflation port 112, only one continuous first inflation channel 140 is required to be connected to the four first inflation chambers 110 in the middle, rather than intermittent first inflation channels 140 being connected to the first inflation chambers 110 respectively, thereby improving the simplicity of the device.

[0106] In some embodiments, the control mechanism 300 includes a first inflation valve body 310 and an elastic seal 353 corresponding to the first space 111, and a first deflation valve body 320 and an elastic seal 353 corresponding to the first space 121; the tail ends of the first inflation valve body 310 and the first deflation valve 320 are respectively connected to different memory alloy wires 510, and the two memory alloy wires 510 and the corresponding elastic seals 353 are respectively configured to control the first inflation valve body 310 and the first deflation valve body 320 to move along the first direction.

[0107] When the first inflation port 112 is opened and the first deflation port 122 is closed, gas enters the gas-using device through the first inflation port 112, the first space 111, and the first gas outlet 113, and the gas-using device is in an inflation state; when the first inflation port 112 and the first deflation port 121 are closed, the gas-using device is in a pressure-maintaining state; when the first inflation port 112 is closed and the first deflation port 121 is opened, gas in the gas-using device is discharged through the first gas outlet 113, the first space 111, the first connecting channel 140, the second space 121, the first deflation port 122, and the first deflation channel 123, and the gas-using device is in a deflation state.

[0108] When the air-using device is in the pressure-maintaining state, the first inflation valve body 310 closes the first inflation port 112 and the first deflation valve body 320 closes the first deflation port 122 , as shown in FIG. 1 . The control valve body in the figure can be either the first inflation valve body 310 or the first deflation valve body 320 .

[0109] When the gas-using device is inflating, the first inflation valve body 310 opens the first inflation port 112, as shown by the first inflation valve body 310 on the right side of Figure 4 , where the arrow indicates the flow of gas. When the gas-using device is deflated, the first deflation valve body 320 opens the first deflation port 122, as shown by the first deflation valve body 320 on the right side of Figure 5 , where the arrow indicates the flow of gas. Each of the first inflation chamber 110 and the first deflation chamber 120 has a first opening 150 at the end away from the first inflation channel 140. The control valve body extends from the first opening 150 at the end away from the first inflation channel 140, and the control valve body is sealedly connected to the first opening 150.

[0110] In some embodiments, the gas distribution mechanism 100 includes a plurality of gas distribution components distributed along the third direction, each gas distribution component includes two second deflation chambers 170 with a third space 171 and a second inflation chamber 160 with a fourth space 161 distributed along the fourth direction.

[0111] The inflation channel includes a second inflation channel 180 provided between the second deflation chamber 170 and the second inflation chamber 160. The extension direction of the second inflation channel 180 is the third direction. Each second inflation chamber 160 has a second inflation port 162 communicating with the second inflation channel 180 and a second air outlet 163 communicating with the air-using device. The second deflation chamber 170 has a second deflation port 172 near the end of the second inflation chamber 160. Each second deflation chamber 170 includes a deflation channel.

[0112] Please refer to Figures 6 to 9. In some embodiments, the third direction is the front-to-back direction, the fourth direction is the left-to-right direction, and the sixth direction is the vertical direction. The second air outlet 163 is provided at the top of the second inflation chamber 160, the second inflation port 162 is provided on the left side of the second inflation chamber 160, the second air release port 172 is provided on the right side of the second air release chamber 170, and the second connecting channel 190 is provided at the top of the valve mechanism 100, extending in the left-to-right direction. Each second air release port 172 is connected to a second air release channel 173. The second air release channel 173 is provided on the right side of the second air release port 172 and on the left side of the second inflation channel 180.

[0113] In some embodiments, please refer to Figures 10-12, the control mechanism 300 includes a second air-deflation valve body 330 and an elastic seal 353 corresponding to it, which are arranged in the third space 171, and a second air-inflating valve body 340 and an elastic seal 353 corresponding to it, which are arranged in the fourth space 161; the tail ends of the second air-inflating valve body 340 and the second air-deflation valve body 330 are respectively connected with different memory alloy wires 510, and the two memory alloy wires 510 and the corresponding elastic seals 353 are respectively configured to control the second air-inflating valve body 340 and the second air-deflation valve body 330 to move along the fourth direction. When the second air-inflating port 162 is opened and the second air-deflation port 172 is closed, the gas enters the air-using device from the second air-inflating port 162, the fourth space 161, and the second air outlet 163, and the air-using device is in an inflated state.

[0114] When the second inflation port 162 is closed and the second deflation port 172 is closed, the gas-using device is in a pressure-maintaining state; when the second inflation port 162 is closed and the second deflation port 172 is opened, the gas in the gas-using device can be discharged through the second gas outlet 163, the second connecting channel 190, the second deflation port 172, and the second deflation channel, and the gas-using device is in a deflated state; the arrows in the figure indicate the direction of gas in the gas-using device in different states.

[0115] Please refer to Figures 7 and 10-12. The second inflation chamber 160 and the second deflation chamber 170 are both provided with a second opening 191 at the ends away from each other. The second inflation valve body 340 extends from the second opening 191 at the end away from the second inflation port 162, and the second deflation valve body 330 extends from the second opening 192 at the end away from the second deflation port 172, and the second inflation valve body 340 or the second deflation valve body 330 is sealed and connected to the second opening 192.

[0116] As shown in FIG. 15 , the valve mechanism 100 has first side walls 194 at both ends along the fourth direction. Each first side wall 194 has a plurality of through holes along the third direction, which serve as second openings 192. Each first side wall 194 can be welded to other structures of the second inflation chamber 160 or the second deflation chamber 170, or can be integrally formed to form the fourth space 161 or the third space 171.

[0117] In some embodiments, the middle of the memory alloy wire 510 is connected to the control valve body, and its two ends are connected to the power supply component through terminals or connectors 530, and the two ends are insulated. The power supply component is configured to supply power to the memory alloy wire 510.

[0118] When the memory alloy wire 510 is energized, it shortens, pulling the first inflation valve body 310 or the first deflation valve body 320 to overcome the elastic force of the elastic seal 353 and move away from the first inflation port 112 or the first deflation port 122, thereby opening the first inflation port 112 or the first deflation port 122. Alternatively, it pulls the second inflation valve body 340 or the second deflation valve body 330 to move away from the second inflation port 162 or the second deflation port 172, thereby opening the second inflation port 162 or the second deflation port 172. The power supply assembly is located at the bottom of the air supply mechanism 400.

[0119] The power supply assembly includes a circuit board 520 disposed at the bottom of the air supply mechanism 400 and a connector 530 disposed on the circuit board 520. Both ends of the memory alloy wire 510 are connected to the circuit board 520 via the connector 530, or directly connected to the circuit board 520 via terminals. The power supply assembly also includes a power supply member 540 disposed on the circuit board 520 for transmitting signals to the circuit board 520.

[0120] Optionally, the circuit board 520 may be a PCB, and the power supply 540 is an external connector provided on the circuit board 520. The external connector may be any one of a power supply, a switch, or a controller. The external connector is connected to an external power source or other electrical components via a wiring harness and is configured to supply power to the circuit board 520. The connector 530 includes a female connector connected to both ends of the memory alloy wire 510, and a male connector provided on the circuit board 520, the female connector and the male connector being plugged in. The structure of the connector is not limited. Optionally, the male and female connectors are interchangeable, compatible, and detachably connected, which is simple and quick to operate, thereby achieving rapid modular installation.

[0121] In some embodiments, the air supply mechanism 400 is provided with a detachable guide rail mechanism 700 . The guide rail mechanism 700 includes guide rails 710 corresponding to each control valve body. The guide rails 710 are configured to define a moving path of the memory alloy wire 510 .

[0122] Please refer to Figures 8-9, 13-18, the air supply mechanism 400 has an air pump cover body 600 near the end of the air distribution mechanism 100, and the middle part of the air pump cover body 600 is connected to the first air ventilation channel 140 or the second air ventilation channel 180. The air pump cover body 600 is provided with a hanging part 610 on the two side walls along the first direction or the fourth direction. The guide rail mechanism 700 includes a guide rail group corresponding to the hanging part 610, and each guide rail group includes a guide rail 710 corresponding to the control valve body, and the guide rail 710 is clamped with the hanging part 610.

[0123] Because the distance between the power supply assembly and the control valve body is relatively large, i.e., the memory alloy wire 510 is relatively long, if the memory alloy wire 510 deviates during the contraction process, it will be impossible to pull the control valve body to open the first inflation port 112 or the second inflation port 162 or the first deflation port 122 or the second deflation port 172. Therefore, the guide rail 710 is provided to guide the movement of the memory alloy wire 510. The guide rails 710 of the same guide rail group can be independently provided or integrated together. In addition, the extension direction of the memory alloy wire 510 can be changed according to the arrangement of the guide rails 710.

[0124] As shown in Figure 16, each guide rail 710 includes a first guide plate 711 and second guide plates 712 arranged on both sides of the first guide plate 711. There is a first gap 715 between each second guide plate 712 and the first guide plate 711. The middle part of the memory alloy wire 510 is hung on the control valve body, and its two ends extend along the two first gaps 715 and are connected to the power supply assembly.

[0125] Each hooking portion 610 includes at least one hooking slot 620 distributed along the second direction or the third direction. A clamping portion 713 is provided at the bottom of at least one guide rail 710 in the guide rail group on the same side. The clamping portion 713 can be inserted into the hooking slot 620, thereby securing the guide rail 710 to the air pump cover 600 and achieving modular installation of the guide rail 710. During assembly, the control valve body is first assembled into the valve mechanism 100, with the tail end extending from the first opening 150 or the second opening 192. The guide rail 710 is then installed in the corresponding position. The middle portion of the memory alloy wire 510 is hooked to the tail end of the control valve body, and the corresponding guide rails 710 extending from both ends are then connected to the connector 530. The connector 530 is then connected to the circuit board 520.

[0126] Specifically, the hanging groove 620 can also be set on the guide rail 710, and the clamping portion 713 can also be set on the hanging portion 610, and modular installation of the two can be achieved; or other clamping structures that can be quickly installed are set at the corresponding positions of the hanging portion 610 and the guide rail 710, all of which fall within the scope of protection of this application.

[0127] Optionally, please refer to Figures 14-16, a third guide plate 714 is further provided at the outer wall of the air supply mechanism 400 corresponding to the guide rail 710, and the third guide plate 714 is arranged on the side of the first guide plate 711 away from the valve mechanism 100, and the memory alloy wires 510 placed in the two first gaps 715 of the same guide rail 710 are placed on both sides of the third guide plate 714.

[0128] The third guide plate 714 guides the movement of the memory alloy wire 510. Furthermore, after the middle portion of the memory alloy wire 510 is attached to the control valve body, its ends are connected to the positive and negative terminals of the power supply assembly, respectively. Therefore, the first and third guide plates 711 and 714 separate the memory alloy wires 510 on either side, preventing them from contacting and causing a short circuit.

[0129] A limiting member 720 is provided on the outer wall of the air supply mechanism 400 . The limiting member 720 is configured to prevent the memory alloy wire 510 from escaping from the guide rail 710 .

[0130] The limiting member 720 includes a first limiting portion 721 provided on both sides of the third guide plate 714. The first limiting portion 721 is a guide plate extending outward from the outer wall of the air supply mechanism 400. A second gap is formed between each first limiting portion 721 and the third guide plate 714. The memory alloy wires 510 placed on both sides of the first guide plate 711 are respectively placed in the second gap.

[0131] The limiting member 720 also includes a second limiting portion 722 arranged at the end of the third guide plate 714 away from the air supply mechanism 400. The second limiting portion 722 extends from the third guide plate 714 to the side close to the two first limiting portions 721. Therefore, the second limiting portion 722 can limit the memory alloy wire 510 from escaping from the second gap, preventing it from escaping from the guide rail 710.

[0132] In some embodiments, each guide rail 710 is provided with a self-pushing rubber sleeve 730 near the end of the control valve body. The self-pushing rubber sleeve 730 is configured to avoid rigid collision between the control valve body and the guide rail 710 when the memory alloy wire 510 is energized and pulls the control valve body connected thereto to move.

[0133] As shown in Figures 10-12 and 14, the position of the self-propelling rubber sleeve 730 corresponds to the rear end of the control valve body. When the memory alloy wire 510 pulls the control valve body toward the self-propelling rubber sleeve 730, it squeezes the self-propelling rubber sleeve 730, causing it to accumulate force. When the memory alloy wire 510 is de-energized, the self-propelling rubber sleeve 730 releases its elastic force, providing a certain driving force for the control valve body and preventing noise caused by impact.

[0134] In some embodiments, the control valve body includes a valve stem 351 and a closing portion 352; one end of the valve stem 351 is connected to the memory alloy wire 510; the closing portion 352 is arranged at the end of the valve stem 351 away from the memory alloy wire 510, and its outer diameter is larger than the outer diameter of the valve stem 351; the elastic sealing member 353 is sleeved on the outside of the valve stem 351.

[0135] Among them, please refer to Figures 3, 7 and 20. The elastic seal 353 is a rubber body or silicone body with a raised structure in the middle and a through hole in the middle of a certain length relative to the control valve body. Its cross-sectional view is shown in Figure 7 or Figure 3. One end of it abuts against the end of the closing portion 352 close to the valve stem 351, and the other end abuts against the inner wall of the first inflation chamber 110 or the second inflation chamber 160 or the first deflation chamber 120 or the second deflation chamber 170; therefore, the elastic seal 353 always closes the first opening 150 or the second opening 192.

[0136] The valve stem 351 extending from the first opening 150 or the second opening 192 is provided with a hooking opening, which faces toward the side closest to the first opening 150 or the second opening 192 and is configured to hook the memory alloy wire 510. A rubber cap 354 is provided on the end of the closing portion 352 away from the valve stem 351. The rubber cap 354 improves the sealing performance of the first inflation port 112, the second inflation port 162, the first deflation port 122, and the second deflation port 172. The outer diameter of the closing portion 352 is smaller than the inner diameter of the chamber in which the control valve body is located, meaning that there is a certain gap between the closing portion 352 and the inner wall of the chamber in which it is located.

[0137] When the memory alloy wire 510 is energized, it pulls the control valve body toward the guide rail 710 to open the first inflation port 112 or the second inflation port 162 or the first air release port 122 or the second air release port 172, thereby squeezing the elastic seal 353, so that the elastic seal 353 is in a force storage state. When the memory alloy wire 510 is de-energized, the elastic seal 353 is in a force release state, driving the control valve body to move toward the side away from the guide rail 710 to close the first inflation port 112 or the second inflation port 162 or the first air release port 122 or the second air release port 172, thereby completing the resetting of the control valve body.

[0138] In some embodiments, the air supply mechanism 400 includes a pump body 420, which is provided with an exhaust port and an air inlet connected to the first air filling channel 140 or the second air filling channel 180. The gas enters the first air filling channel 140 or the second air filling channel 180 through the air inlet, the pump body 420, and the exhaust port to supply air to the air distribution component.

[0139] The control device further includes a controller housing 800. The gas distribution mechanism 100, the gas supply mechanism 400, and the drive mechanism 500 are all disposed within the controller housing 800. The controller housing 800 includes a first housing 810 disposed at the top and a second housing 820 disposed at the bottom. The second housing 820 is wrapped around the first housing 810 near its end.

[0140] As shown in Figures 4 and 11 , an air supply channel 440 is provided at the bottom of the first air filling channel 140 or the second air filling channel 180. The air supply channel 440 extends vertically, and the exhaust port of the air supply mechanism 400 is connected to the air supply channel 440. Specifically, the end of the second shell 820 near the first shell 810 can also be enclosed within the first shell 810.

[0141] Referring to FIG. 21 , a circulation space 830 is formed between the first housing 810 and the outer walls of the gas distribution mechanism 100 and the gas supply mechanism 400. The guide rail mechanism 700 and the memory alloy wire 510 are both disposed within the circulation space 830. An exhaust opening 821 is provided on the second housing 820. The exhaust opening 821 can also be disposed on the first housing 810 or at the location where the first and second housings 810 and 820 are fastened. Optionally, the exhaust opening 821 is disposed near the lower end, near the connector 530, to facilitate cooling of the entire length of the memory alloy wire 510.

[0142] In some embodiments, at least one air leakage hole 193 is provided at both ends of the gas distribution mechanism 100 along the fourth direction, and each second air leakage channel 173 is connected to the air leakage hole 193. The gas can pass through the second air outlet 163, the second connecting channel 190, the second air leakage port 172, and the second air leakage channel 173, and be discharged from the air leakage hole 193 to cool the memory alloy wire 510.

[0143] Referring to Figures 8, 12, and 19, a third communication channel is further provided within the air distribution mechanism. This third communication channel is located at the end of each air distribution assembly near the air supply mechanism 400. The third communication channel extends in the fourth direction and communicates with the second air relief channel 173 and the air relief hole 193. When the first air relief valve body 320 or the second air relief valve body 330 opens the first air relief port 122 or the second air relief port 172 under the action of the memory alloy wire 510, the first air relief valve body 320 or the second air relief valve body 330 abuts against the self-propelled rubber sleeve 730, squeezing the self-propelled rubber sleeve 730.

[0144] As shown in Figure 17, each guide rail 710 is provided with a mounting hole 750 near the end of the hanging part 610. The mounting hole 750 is configured to install a self-pushing rubber sleeve 730. The self-pushing rubber sleeve 730 is adapted to the mounting hole 750 to close the mounting hole 750. The gas discharged from the first air vent 122 is discharged into the circulation space 830 through the first air vent channel 123 and the first gap 715; the gas discharged from the second air vent 172 is discharged into the circulation space 830 through the second air vent channel 173, the air vent hole 193, and the first gap 715; the gas in the circulation space 830 is discharged to the outside through the exhaust opening 821, so the memory alloy wire 510 can be cooled.

[0145] Optionally, the end surface areas of the self-pushing rubber sleeve 730 and the first air relief valve body 320 or the second air relief valve body 330 that are close to each other are inconsistent, or there are grooves or holes designed on the end surfaces, so that even when the two are in contact again, there is a gap between them; the gas discharged from the first air relief port 122 is discharged into the circulation space 830 through the first air relief channel 123, the gap gap, and the first gap 715; the gas discharged from the second air relief port 172 is discharged into the circulation space 830 through the second air relief channel 173, the air relief hole 193, the gap gap, and the first gap 715; the gas in the circulation space 830 is discharged to the outside through the exhaust opening 821, so the memory alloy wire 510 can be cooled.

[0146] Optionally, the outer diameter of the self-propelling rubber sleeve 730 is smaller than the inner diameter of the mounting hole 750, thereby forming a third gap between the self-propelling rubber sleeve 730 and the inner wall of the mounting hole 750. Each guide rail 710 is provided with a first through hole at the third gap. Gas discharged from the first air vent 122 is discharged into the circulation space 830 and the first gap 715 through the first air vent channel 123, the third gap, and the first through hole. Gas discharged from the second air vent 172 is discharged into the circulation space 830 and the first gap 715 through the second air vent channel 173, the air vent 193, the third gap, and the first through hole. Gas is then discharged to the outside through the exhaust opening 821. Since the memory alloy wire 510 is disposed in the circulation space 830, the gas passing through the circulation space 830 can cool the memory alloy wire 510.

[0147] Optionally, an air inlet opening 822 is further provided on the second shell, and the air supply mechanism 400 also includes a motor 430 provided at the bottom of the pump body 420. An air inlet channel 840 connected to the air inlet opening 822 is provided outside the pump body 420 and the motor 430. The air inlet channel 840 is connected to the air inlet, and an eccentric wheel is provided at the output end of the motor 430. When the motor 430 is started, the eccentric wheel is driven to rotate, so that the pump body 420 can be operated to blow the gas at the air inlet to the exhaust port, and then enter the first inflation channel 140 or the second inflation channel 180. The air intake and the air discharge are separated, so that the air intake is a relatively normal temperature gas, and the process of the air discharge out of the controller shell 800 can take away the heat of the memory alloy wire, effectively avoiding the heat accumulation at the position of the memory alloy wire 510 and ensuring the performance of the memory alloy wire 510.

[0148] In some embodiments, as shown in Figure 22, the air pump cover body 600 is also provided with a guide rail group on both sides along the second direction or the third direction, and the air distribution mechanism 100 is provided with an air distribution component connected to the guide rail group, and the air distribution component is provided with a control valve body, and the moving direction of the control valve body is the second direction or the third direction, and also includes a corresponding driving mechanism 500 for driving the control valve body to move.

[0149] The present application provides a pneumatic system including the aforementioned pump-valve integrated control device for a pneumatic support sac, and also including an air bag 200 connected to the air distribution mechanism 100 via a quick-connect coupling 210.

[0150] In this embodiment, the air-using device is an air bag 200. The number, form and shape of the air bags 200 can be designed differently according to the situation.

[0151] As shown in Figures 10 and 23, the first air outlet 113 and the second air outlet 163 are each provided with an air outlet nozzle 240. Each air outlet nozzle 240 is connected to a quick-connect connector 210. A sealing gasket 230 is provided between the quick-connect connector 210 and the air outlet nozzle 240 to prevent gas leakage. Optionally, the gas-using device is an air bag 200. The quick-connect connector 210 and the air bag 200 can be connected via a quick-connect plug 250. The bottom of the quick-connect connector 210 and the air outlet nozzle 240 can be quickly installed, improving the speed of assembly. Each air bag 200 has three states: inflation, deflation, and pressure maintenance. The air bag can be switched between these three states by cooperating with the memory alloy wire 510 and the elastic seal 353. The air bag can be used as a lumbar support air bag, a side support air bag, a headrest support air bag, a leg support air bag, or a softness and hardness adjustment air bag, etc.

[0152] The present application also proposes a vehicle-use pneumatic massage control pump-valve integrated device, as shown in Figures 24-29, which includes an air supply mechanism 3 configured to provide high-pressure gas and multiple valve body components arranged at the top of the air supply mechanism 3.

[0153] The valve body assembly includes a sliding valve body 2, an elastic component 25 mounted thereon, and a drive mechanism 4. The drive mechanism 4 includes a power supply assembly 42 and a corresponding number of memory alloy wires 41 as the valve body assembly. The power supply assembly 42 is placed at the bottom of the air supply structure 3. The middle part of the memory alloy wire 42 is connected to the sliding valve body 2, and its two ends extend downward along the side wall of the air supply structure 3 and connect to the power supply assembly 42 placed at the bottom of the air supply structure 3.

[0154] The integrated pump-valve device also includes an integrated gas distribution mechanism 1 arranged at the top of the gas supply mechanism 3, with an air charging channel 11 in the middle, which receives the gas output by the gas supply mechanism 3, and gas distribution parts are provided on both sides along its extension direction.

[0155] Each gas distribution part includes at least one gas distribution chamber 12, each gas distribution chamber 12 has a first space, the first space has a gas filling port 124 connected to the gas filling channel 11, a gas outlet 126 at the top, and a gas discharge port 125 away from the gas filling port 124.

[0156] Among them, the arrows in Figures 24 and 27-29 indicate the direction of the gas in the inflation channel 11 supplying gas to each gas distribution chamber 12; optionally, please refer to Figure 27, the gas distribution part includes five gas distribution chambers 12, and the gas distribution chambers 12 corresponding to different gas distribution parts are symmetrically arranged.

[0157] Each valve body assembly is correspondingly assembled to the air distribution chamber 12, one end of the sliding valve body 2 and the elastic assembly 25 are arranged in the first space, and the other end extends out from the air release port 125; the sliding valve body 2 has a first state and a second state. When in the first state, the sliding valve body 2 closes the inflation port 124, at this time, the air outlet 126 and the air release port 125 are connected; when in the second state, the sliding valve body 2 opens the inflation port 124, closes the air release port 125, and the inflation port 124 and the air outlet 125 are connected.

[0158] Please refer to Figures 24 and 25, the sliding valve body 2 on the right is in the second state, the sliding valve body 2 opens the inflation port 124, the gas enters the first space through the inflation channel 11 and the inflation port 124, and enters the air outlet 126, and the direction of the gas is shown by the arrow; please refer to Figures 30 and 31, the sliding valve body 2 on the right is in the first state, the sliding valve body 2 closes the inflation port 124, and the gas is discharged through the air outlet 126, the first space, and the air release port 125, and the direction of the gas is shown by the arrow.

[0159] In the natural state, the sliding valve body 2 is in the first state. When the memory alloy wire 41 is energized and de-energized, the elastic component 25 cooperates to switch the sliding valve body 2 between the first state and the second state. The control of the sliding valve body 2 by each driving mechanism 4 is independent of each other.

[0160] When in use, the air inlet port of the air-using device is connected to the air outlet 126 at the top of the air distribution chamber 12 of the sliding valve body 2, and the driving mechanism 4 corresponding to the sliding valve body 2 is installed, and the air-using device is inflated or deflated through the cooperation of the driving mechanism 4 and the elastic component 25; since the control of each sliding valve body 2 is independent of each other, and in the natural state, the other sliding valve bodies 2 are in the first state, there will be no impact on other air-using devices; therefore, the present application can install the corresponding driving mechanism 4 according to actual needs, and there is no need to install all the driving mechanisms 4 that control all the sliding valve bodies 2. A modular design is adopted, and the modules do not affect each other, which is convenient to install, has stronger applicability, and saves manpower and material resources.

[0161] In some embodiments, when the sliding valve body 2 is not installed in the air distribution chamber 12 , a sealing member is required to seal the corresponding inflation port 124 .

[0162] Among them, when the air distribution part includes multiple air distribution chambers 12, and some air distribution chambers 12 are not installed with sliding valve bodies 2, the corresponding inflation ports 124 need to be sealed by sealing members to prevent gas from entering the inflation ports 124 through the inflation channel 11 and being exhausted through the corresponding air outlets 126 and air vents 125, thereby affecting the air supply to other air distribution chambers 12.

[0163] In some embodiments, the outer wall of the valve mechanism is detachably connected to a guide rail group 5 , each guide rail group 5 is provided with a guide rail 51 corresponding to each sliding valve body 2 , and the guide rail 51 is configured to limit the moving path of the memory alloy wire 41 .

[0164] As shown in Figures 33 and 34 , the gas distribution mechanism 1 includes a connecting assembly disposed at the bottom of the gas distribution unit. A hooking portion 61 is provided on the outer wall of the connecting assembly, and the guide rail assembly 5 engages with the hooking portion 61. Due to the large distance between the power supply assembly 42 and the sliding valve body 2, i.e., the long memory alloy wire 41, if the memory alloy wire 41 deviates during contraction, it will be impossible to pull the sliding valve body 2 away from the inflation port 124, resulting in an inability to complete the transition from the first state to the second state. Therefore, the guide rail 51 is provided to guide the movement of the memory alloy wire 41. Furthermore, the guide rail 51 serves to smoothly transition the memory alloy wire 41 from parallel to the rear end of the sliding valve body 2 to extend along the outer wall of the gas supply mechanism 3.

[0165] In some embodiments, each guide rail 51 includes a first guide plate 511 and a second guide plate 512 arranged on both sides of the first guide plate 511. There is a first gap between each second guide plate 512 and the first guide plate 511. The middle part of the memory alloy wire 41 is hung on the sliding valve body 2, and its two ends extend along the two first gaps and are connected to the power supply component 42.

[0166] Please refer to Figures 28-29, 32 and 33. Each hanging portion 61 includes at least one hanging groove 611. The bottom of at least one guide rail 51 in the guide rail group 5 on the same side is provided with a clamping portion 513, and the clamping portion 513 can be inserted into the hanging groove 611, so that the guide rail 52 is fixed on the valve mechanism 1, realizing the modular installation of the guide rail 51.

[0167] Optionally, a third guide plate 52 is further provided at the outer wall of the air supply mechanism 3 corresponding to the guide rail 51. The third guide plate 52 is arranged on the side of the first guide plate 511 away from the valve mechanism 1, and the memory alloy wires 41 placed in the two first gaps of the same guide rail 51 are placed on both sides of the third guide plate 52.

[0168] As shown in Figures 32 and 33 , the third guide plate 52 guides the movement of the memory alloy wire 41. Furthermore, after the middle portion of the memory alloy wire 41 is attached to the sliding valve body 2, its ends are connected to the positive and negative electrodes of the power supply assembly 42, respectively. Therefore, the first guide plate 511 and the third guide plate 52 separate the memory alloy wires 41 on either side, preventing short circuits caused by contact between the memory alloy wires 41 on both sides.

[0169] In some embodiments, each guide rail 51 is provided with a limiter 53 , which is configured to prevent portions of the same memory alloy wire 41 placed in different first gaps from touching each other, and to prevent adjacent memory alloy wires 41 from touching each other.

[0170] Referring to Figures 32 and 33 , the limiting member 53 includes first limiting portions 531 disposed on either side of the third guide plate 52. The first limiting portions 531 are guide plates extending outward from the outer wall of the air supply mechanism 3. A second gap is formed between each first limiting portion 531 and the third guide plate 52. The memory alloy wires 41 disposed on either side of the first guide plate 511 are positioned within the second gap. The limiting member 53 also includes second limiting portions 532 disposed at the end of the third guide plate 52 away from the air supply mechanism 3. The second limiting portions 532 extend from the third guide plate 52 toward the side closer to the two first limiting portions 531. Therefore, the second limiting portions 532 restrict the memory alloy wires 41 from escaping from the second gap, thereby preventing the memory alloy wires 41 disposed in different first gaps from touching or adjacent memory alloy wires 41 from touching, causing a short circuit.

[0171] In some embodiments, the sliding valve body 2 has an air release channel 21. When the sliding valve body 2 is in a first state, the air release channel 21 is connected to the first space, and the gas can be discharged from the air outlet 126, the first space, and the air release channel 21; when the sliding valve body 2 is in a second state, the air release channel 21 is closed, and the inflation channel 11, the first space, and the air outlet 126 are connected.

[0172] Among them, please refer to Figures 24 and 30. When any air outlet is connected to a gas-using device, in the natural state and when the sliding valve body 2 is in the first state, the inflation port 124 is closed, and the gas cannot enter the first space through the inflation channel 11, and thus the gas-using device cannot be inflated; when the sliding valve body 2 is in the second state, the inflation port 124 is opened, and the gas is inflated to the gas-using device through the inflation channel 11, the first space and the air outlet 126, and the gas-using device is in an inflated state; when the sliding valve body 2 switches from the second state to the first state, the deflation channel 21 is opened and the inflation port 124 is closed, so the air pressure in the first space is reduced, and the gas in the gas-using device is discharged from the air outlet 126 to the first space, and then discharged through the deflation channel 21, and the gas-using device is in a deflated state.

[0173] In some embodiments, referring to FIG. 27 and FIG. 35 , the sliding valve body 2 includes a valve core 22 , a valve cap 23 and a sealing ring 24 .

[0174] The valve core 22 includes a first blocking portion 221, a second blocking portion 222 and a valve stem 223 in the direction from the inflation channel 11 to the deflation port 125. The valve stem 223 extends out from the deflation port 125 at the end away from the inflation channel 11.

[0175] The valve stem 223 exposed outside the gas distribution chamber 12 is provided with a hanging opening 2231, the opening of the hanging opening 2231 is toward the side close to the inflation channel 11, and the hanging opening 2231 is configured to hang the memory alloy wire 41

[0176] The valve cap is arranged on the side of the first blocking portion 221 close to the inflation channel 11. When the sliding valve body 2 is in the first state, the valve cap 23 closes the inflation port 124.

[0177] The valve cap 23 is made of rubber, silicone or other soft elastic materials. The valve cap 23 blocks the inflation port 124 to improve the sealing performance.

[0178] The sealing ring 24 is sleeved on the end of the valve stem 223 near the second blocking portion 222. When the sliding valve body 2 is in the second state, the two sides of the sealing ring 24 are in close contact with the inner wall of the gas distribution chamber 12 and the end face of the second blocking portion 222 near the valve stem 223, and the air leakage channel 21 is isolated from the first space gas path; when the sliding valve body 2 is in the first state, the sealing ring 24 is separated from the inner wall of the gas distribution chamber 12, and the air leakage channel 21 is connected to the first space gas path.

[0179] The air release channel 21 is a groove formed at the bottom of the valve stem 223, which can extend from the tail of the valve stem 223 to the end of the second blocking portion 222 close to the valve stem 223, or can extend to the corresponding end of the sealing ring 24 away from the second blocking portion 222; the sealing ring 24 is made of rubber, and the sealing ring 24 can be fixed to the end of the second blocking portion 222 close to the valve stem 223 by bonding. When the sliding valve body 2 is in the first state, as shown in the sliding valve body 2 on the right side of Figures 30 and 31, a third gap is present between the end of the second blocking portion 222 away from the inflation channel 11 and the inner wall of the gas distribution chamber 12. Along the left and right directions, the width of the third gap is greater than the width of the sealing ring 24. Therefore, when the sliding valve body 2 is in the first state, there is a certain distance between the end of the sealing ring 24 away from the inflation channel 11 and the inner wall of the gas distribution chamber 12. Therefore, gas can enter the air release channel 21 from the first space and be discharged from the air release channel 21 outside the gas distribution chamber 12.

[0180] When the sliding valve body is in the second state, such as the sliding valve body 2 on the right side of Figures 24 and 25, under the action of the memory alloy wire 41, the sliding valve body 2 moves away from the end of the inflation channel 11, so that the third gap gradually decreases until the sealing ring 24 is squeezed. The sealing ring 24 then closes the third gap, so that the gas cannot enter the deflation channel 21 from the first space.

[0181] In summary, when the sliding valve body 2 is in the second state, the inflation port 124 is opened and the deflation channel 21 is closed, so the air-using device corresponding to the sliding valve body 2 is in the inflation state; when the sliding valve body 2 switches from the second state to the first state, the inflation port 124 is closed and the deflation channel 21 is opened, so the air-using device corresponding to the sliding valve body 2 is in the deflation state.

[0182] Optionally, the elastic component 25 is sleeved outside the sealing ring 24, with one end of the elastic component 25 abutting against the end of the first blocking portion 221 near the second blocking portion 222, and the other end abutting against the inner wall of the air distribution chamber 12. Optionally, the elastic component 25 is a return spring. When the memory alloy wire 41 is energized, the memory alloy wire 41 contracts, pulling the sliding valve body 2 away from the inflation channel 11. Therefore, the return spring is compressed under the pressure of the first blocking portion 221 and the inner wall of the air distribution chamber 12. At this time, the return spring is in a charged state. When the memory alloy wire 41 is de-energized, the pulling force on the sliding valve body 2 disappears, the return spring releases its force, and pushes the first blocking portion 221 toward the inflation channel 11.

[0183] As shown in Figures 30 and 33, a self-pushing rubber block 26 is provided on the side of the first guide plate 511 near the sliding valve body 2. When the sliding valve body 2 is in the second state, the valve stem 223 squeezes the self-pushing rubber block 26 to prevent the valve stem 223 from rigidly colliding with the guide rail 51, thereby playing a role in shock absorption and noise reduction. In addition, when the sliding valve body 2 switches from the second state to the first state, the self-pushing rubber block 26 will also release elastic force to the sliding valve body 2 to provide a certain driving force.

[0184] In some embodiments, the power supply assembly 42 includes a circuit board 421 located at the bottom of the air supply mechanism 3 and a connector 422 located on the circuit board 421. The two ends of the memory alloy wire 41 are connected to the circuit board 421 through the connector 422, or directly connected to the circuit board 421 through terminals.

[0186] In some embodiments, the connector 422 includes a female connector 4221 connected to both ends of the memory alloy wire 41 , and a male connector 4222 provided on the circuit board 421 , and the female connector 4221 and the male connector 4222 are plugged into each other.

[0187] Among them, the structure of the connector 422 is not limited. Optionally, please refer to Figure 33. The male connector 4222 and the female connector 4221 are interchangeable. The male connector 4222 and the female connector 4221 are adaptable and detachably connected. The operation is simple and fast.

The controller housing 7 is also provided with a second opening 72. The air supply mechanism 3 is an air pump, which also includes a motor 32. An air supply channel 34 is provided on one side of the motor 32. One end of the air supply channel 34 is connected to the second opening 72, and the other end is connected to the air inlet 312.

The output end of the motor 32 is fixedly connected to an eccentric wheel. When the motor 32 is started to drive the eccentric wheel to rotate, the gas in the air inlet 312 will be formed into an airflow and discharged from the exhaust port 311 to the inflation channel 11. The arrows in the figure indicate the direction of the gas.

[0191] Optionally, as shown in FIG33 , a third opening 73 is provided at the bottom of the controller housing or the controller housing 7 , and the external connector of the power supply assembly 42 extends out from the third opening 73 and is exposed to the outside, so as to facilitate powering the external connector with an external power source.
