Description

Technical Field

[0001] The present invention relates to an integrated air valve structure, and more particularly to an integrated air valve structure capable of achieving air intake, exhaust or maintenance on a single ventilation path. Background Art

[0002] According to CN100543360C, an air bag inflation and exhaust system and an air valve assembly used therein are disclosed. The air valve assembly uses multiple air valves to achieve inflation and exhaust control, but the air valve assembly only uses a single air channel (i.e., the main air channel in this case), which results in the air pressure in the air channel possibly causing an erroneous flow when the air valves are in a switching state. Furthermore, when one of the air valves used for exhaust is activated, the gas in the air channel is not only discharged through one of the air valves, but also flows back to an air supply source through the same air channel. Summary of the invention

[0003] The main purpose of the present invention is to solve the existing problem of exhaust gas backflow.

[0004] The secondary purpose of the present invention is to solve the problems derived from the complex structure of the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides an integrated air valve structure, comprising a main body and two air valves. The main body is formed with two air passages that are not connected to each other, a plurality of through holes respectively corresponding to the two air passages, and two valve mounting seats, one of the two valve mounting seats is corresponding to one of the through holes, and the other of the two valve mounting seats is corresponding to two of the through holes belonging to the two air passages. The two air valves are arranged on the two valve mounting seats, and each of the two air valves has an air plug facing at least one of the through holes, a valve seat assembled with one of the two valve mounting seats and providing the air plug with movement therein, and a coil arranged on the valve seat and generating a magnetic force to change the position of the air plug based on the power-on condition. Among them, one of the two air valves determines the connection of the two air passages to achieve air intake, and the other of the two air valves determines whether one of the two air passages is connected to the outside to achieve exhaust, and the two air valves jointly determine whether the integrated air valve structure enters air pressure maintenance.

[0006] In one embodiment, the gas plug used for exhausting one of the two gas valves has an exhaust passage, and the valve seat has an exhaust hole connected to the exhaust passage.

[0007] In one embodiment, one of the two valve mounting seats corresponding to one of the two gas valves for exhausting one of the two gas valves has an exhaust hole.

[0008] In one embodiment, each of the two air valves has an elastic member for returning the air plug.

[0009] In one embodiment, each of the two gas valves has a gas-tight ring disposed on the valve seat and contacting one of the two valve mounting seats.

[0010] In one embodiment, the gas plug comprises a plug body acted upon by the coil, and a plug cover disposed on the plug body and facing at least one of the through holes.

[0011] In one embodiment, the main body is formed with at least one auxiliary airtight ring corresponding to one of the through holes.

[0012] In one embodiment, the main body is formed with a partition wall separating the two air passages.

[0013] Through the above implementation of the present invention, compared with the prior art, the present invention has the following characteristics: the two air passages formed on the body of the present invention are not directly connected, which can prevent the gas from flowing back to a gas supply source during exhaust. In addition, the installation structure of the two air valves of the present invention can shorten the installation time and reduce the difficulty of subsequent maintenance operations.

[0045] The detailed description and technical contents of the present invention are now described as follows with reference to the accompanying drawings:

[0046] See also Figures 1 to 4The present invention provides an integrated gas valve structure 20, comprising a body 21 and two gas valves 22. The body 21 is formed with two gas passages 211, a plurality of through holes 212, and two valve mounting seats 213. The two gas passages 211 can be connected to a gas duct 30 respectively. Although the two gas passages 211 are formed in the body 21 at the same time, the two gas passages 211 are not connected to each other. Moreover, the through holes 212 are respectively arranged corresponding to the two gas passages 211. More specifically, each of the through holes 212 is only arranged corresponding to one of the two gas passages 211. Moreover, the two valve mounting seats 213 each have a space 214 for the two gas valves 22 to be arranged. One of the two valve mounting seats 213 is arranged corresponding to one of the through holes 212, and the other of the two valve mounting seats 213 is arranged corresponding to at least two of the through holes 212. At least two of the through holes 212 respectively correspond to the two air channels 211. When at least two of the through holes 212 are not covered, the two air channels 211 can be connected through the space 214 formed by at least two of the through holes 212 and the corresponding ones of the two valve mounting seats 213.

[0047] Please refer to Figures 2 to 4 The two gas valves 22 are arranged on the two valve mounting seats 213. Each of the two gas valves 22 has an air plug 221, a valve seat 222, and a coil 223. The air plug 221 faces at least one of the through holes 212 located in one of the two valve mounting seats 213. The air plug 221 can move relative to the valve seat 222. The air plug 221 can be controlled to change its position in the space 214. More specifically, the air plug 221 has a first position blocking at least one of the through holes 212 and a second position releasing at least one of the through holes 212. The valve seat 222 is assembled with one of the two valve mounting seats 213. The valve seat 222 is formed with a housing space 224 for the air plug 221 to be placed and moved. On the other hand, the coil 223 is arranged on the valve seat 222. The coil 223 is connected to an external power supply device 40 to obtain the power required for operation. The coil 223 generates magnetic force based on the energized state to change the position of the air plug 221. As can be seen from the foregoing, the two air valves 22 of the present invention are implemented with a solenoid valve structure to produce precise control and rapid response. Furthermore, each of the two air valves 22 works independently, that is, the action of one of the two air valves 22 is not linked.

[0048] The integrated air valve structure 20 of the present invention can realize air intake, exhaust or maintenance on a single ventilation path. In other words, the integrated air valve structure 20 is one of the components constituting the aforementioned ventilation path, and the state of the integrated air valve structure 20 will change the conditions in the aforementioned ventilation path. Further, one of the two air valves 22 of the present invention determines the connection of the two air passages 211 to achieve air intake, and the other of the two air valves 22 determines whether one of the two air passages 211 is connected to the outside to achieve exhaust, and the two air valves 22 jointly determine whether the integrated air valve structure 20 enters air pressure maintenance.

[0049] As mentioned above, at the beginning of the implementation of the integrated air valve structure 20, one of the two air passages 211 can be connected to an air supply source 31 (such as a pump) through the air guide tube 30, and the other of the two air passages 211 can be connected to an inflatable element 32 (such as an air bag) through the other air guide tube 30. Assuming that the current state is that the two air valves 22 on the integrated air valve structure 20 are not in effect, the air plug 221 of each of the two air valves 22 is located at the first position, such as Figure 2 Please refer to Figure 3 When the inflatable element 32 is to be inflated, the coil 223 corresponding to at least two of the through holes 212 in the two air valves 22 is energized to generate magnetic force, so that the air plug 221 of one of the two air valves 22 is moved from the first position to the second position, and the two air passages 211 are connected to the space 214 in one of the two valve mounting seats 213 through at least two of the through holes 212, and the gas provided by the air supply source 31 is able to flow in the two air passages 211 in sequence to inflate the inflatable element 32.

[0050] Please refer to Figure 2 When the air pressure in the inflatable element 32 is to be maintained, the multiple air plugs 221 of the two air valves 22 on the integrated air valve structure 20 will be controlled to be in the first position to achieve air pressure maintenance.

[0051] Please refer to Figure 4 When the air pressure in the inflatable element 32 is reduced, that is, the inflatable element 32 is deflated, the coil 223 of one of the two air valves 22 corresponding to at least one of the through holes 212 is energized, so that the air plug 221 of one of the two air valves 22 is moved from the first position to the second position, and one of the two air passages 211 is connected to the external environment through at least one of the through holes 212 that is released, thereby achieving exhaust.

[0052] As mentioned above, the two air passages 211 formed on the body 21 of the present invention are not directly connected, and there is a partition wall 216 directly formed by the body 21 between the two air passages 211. The partition wall 216 separates the two air passages 211, so that the two air passages 211 do not directly communicate with each other. The partition wall 216 and one of the two air valves 22 can prevent the gas from flowing back to the air supply source 31 when exhausting. Furthermore, the air supply source 31 and the inflatable element 32 can be set at the same horizontal height, so that the space requirement can be reduced. The installation structure of the two air valves 22 of the present invention can shorten the installation time and reduce the difficulty of subsequent maintenance operations.

[0053] Please refer to Figure 2 and Figure 3 The gas plug 221 used for exhausting one of the two gas valves 22 has an exhaust passage 225, and the valve seat 222 of one of the two gas valves 22 has an exhaust hole 226 connected to the exhaust passage 225. In addition, one end of the exhaust passage 225 is connected to the space 214 formed by one of the two valve mounting seats 213, and the other end of the exhaust passage 225 is connected to the exhaust hole 226. Furthermore, the exhaust passage 225 does not affect the gas blocking of at least one of the through holes 212 by the gas plug 221 in principle. Please refer to Figure 5 In addition to the above, in another embodiment, the gas plug 221 does not have the exhaust channel 225, and the exhaust hole 226 originally formed on the valve seat 222 is instead formed on the two valve mounting seats 213. In this way, once the gas plug 221 is switched from the first position to the second position, at least one of the through holes 212 that are released is connected to the exhaust hole 226 through the space 214 on one of the two valve mounting seats 213 to achieve exhaust.

[0054] Please refer to Figures 2 to 4 In one embodiment, each of the two air valves 22 has an elastic member 227 for returning the air plug 221. The elastic member 227 can be a spring or the like that can store a rebound force. Two ends of the elastic member 227 respectively abut against the air plug 221 and the valve seat 222. When the air plug 221 is not acted upon by the magnetic force generated by the coil 223, the elastic member 227 pushes the air plug 221 to move toward at least one direction of the through holes 212.

[0055] Please refer to Figures 2 to 4 In one embodiment, each of the two air valves 22 has an airtight ring 228, which is disposed on the valve seat 222 and contacts one of the two valve mounting seats 213. This prevents the occurrence of erroneous air leakage.

[0056] Please refer to Figures 2 to 4In one embodiment, the gas plug 221 has a plug body 229 and a plug cover 220. A portion of the plug body 229 is accommodated in the valve seat 222, and the plug body 229 can be acted upon by the coil 223. Moreover, the plug cover 220 can be made of a soft rubber material, and the plug cover 220 is disposed on the plug body 229 and faces at least one of the through holes 212.

[0057] Please refer to Figures 2 to 4 In one embodiment, the body 21 is formed with at least one auxiliary airtight ring 215, and the at least one auxiliary airtight ring 215 is disposed corresponding to one of the through holes 212. The at least one auxiliary airtight ring 215 is actually an annular convex rib forming the periphery of one of the through holes 212. When the air plug 221 is in the first position, it can contact the at least one auxiliary airtight ring 215 to increase the airtight effect.

[0058] The integrated valve structure 20 of the present invention can be multiple to form a valve device 50, such as Figure 1 shown.

[0059] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
