Among them, the air valve is installed on the air pump using a valve seat, and the air valve and the valve seat are usually connected by a snap-on connection. When disassembling or installing the air valve and the valve seat, it is necessary to manually apply a corresponding external force to make the snap-on structure elastically deform, thereby facilitating the separation or combination of the snap-on structure and completing the installation or disassembly of the air valve and the valve seat.

[0043] See also Figures 1 to 4 As shown, the air source device 1000 of the embodiment of the utility model is an air source device 1000 with an integrated pump and valve, and the air source device 1000 includes an air pump 1 and at least one air valve 3. Among them, at least one air valve 3 is assembled on the air pump 1 through a valve seat 2, and each air valve 3 is ventilated and connected to the air pump 1, so that the air valve 3 and the air pump 1 are integrated.

[0044] It can be understood that the air pump 1 is a pump device capable of supplying airflow, including but not limited to a piston air pump, a membrane air pump, a screw air pump, a vortex air pump, a diaphragm micro pump, etc. Among them, the air pump 1 has an air outlet 11 for outputting airflow, and the air outlet 11 is ventilated and connected to at least one air valve 3 through a valve seat 2. During the air supply process of the air pump 1 outputting airflow to the outside through the air outlet 11, at least one air valve 3 ventilated and connected to the air outlet 11 can be used to split the air flow to form multiple air paths, and the at least one air valve 3 can control the air supply status of the corresponding air paths respectively.

[0045] Among them, see Figure 5 and Figure 6The valve seat 2 has at least one airflow outlet 22. After the valve seat 2 is assembled on the air pump 1, at least one airflow outlet 22 is connected to the air outlet 11 of the air pump 1. Specifically, the valve seat 2 has several sockets 24 corresponding to the several air outlets 11 of the air pump 1 and capable of receiving the corresponding airflows, and at least one airflow outlet 22 is connected to several sockets 24 to achieve the connection between at least one airflow outlet 22 and the air outlet 11 of the air pump 1. At least one air valve 3 is assembled on the valve seat 2, and each air valve 3 is connected to an airflow outlet 22, so that the airflow output from the air outlet 11 of the air pump 1 can be diverted from at least one airflow outlet 22 and output to at least one air valve 3.

[0046] In some preferred embodiments, the air pump 1 can be selected as a diaphragm micro pump, which includes a driving motor, a driving plate, a plurality of air bags / leather cups, a shell and an airway plate. Among them, the output shaft of the driving motor is eccentrically connected to the driving plate, which can drive the driving plate to deflect; the plurality of air bags / leather cups are connected to the driving plate, and can produce volume changes with the deflection of the driving plate; one end of the shell is sealed to the driving motor, and the other end is sealed to the airway plate, and a accommodating space is formed inside, and an air inlet channel connected to the accommodating space is provided on the shell; a plurality of air inlet holes and a plurality of air outlet holes are provided on the airway plate, wherein each air inlet hole is respectively connected to the volume space of an air bag / leather cup and the accommodating space, and each air outlet hole is respectively connected to the volume space of an air bag / leather cup, and the air outlet hole is corresponding to the air outlet 11 of the air pump 1. In this preferred embodiment, the air pump 1 is set to have a plurality of air outlets 11. In addition, the valve seat 2 is provided with a plurality of sockets 24 on the side facing the airway plate, each socket 24 corresponds to an air outlet and can receive the airflow generated by the corresponding air bag / leather cup during the volume change process; and the other side of the valve seat 2 facing away from the airway plate is provided with a plurality of airflow outlets 22, and the plurality of airflow outlets 22 are connected to the plurality of sockets 24.

[0047] Specifically, in some preferred embodiments, each air flow outlet 22 corresponds to a socket 24 and is connected through a corresponding connecting hole. Among them, each air flow outlet 22 and the corresponding socket 24 are located at both ends of the corresponding connecting hole. After the corresponding socket 24 receives the airflow of the corresponding air bag / leather cup volume change, it can be guided to the corresponding air flow outlet 22 through the corresponding connecting hole. Further, multiple sockets 24 can be connected to each other through air flow channels, so that the airflow output from each air outlet 11 of the air pump 1 can be received by the corresponding socket 24, and can be diverted to multiple sockets 24 and diverted and output by each socket 24 at the corresponding air flow outlet 22, respectively, to ensure the working efficiency and air supply stability of the air pump 1.

[0048] In other preferred embodiments, the plurality of sockets 24 can be connected to each other through the converging flow channel on the same side as the plurality of sockets 24, and the plurality of airflow outlets 22 can be connected to each other through the diverging flow channel on the same side as the plurality of airflow outlets 22, and a through hole connecting the converging flow channel and the diverging flow channel is provided on the valve seat 2. The airflow output from each air outlet 11 of the air pump 1 is received by the corresponding sockets 24, converges at the through hole through the converging flow channel, and flows into the diverging flow channel on the other side to be diverted to the plurality of airflow outlets 22 for diversion output, so that the airflow output from each air outlet 11 of the air pump 1 is received by the corresponding sockets 24, converges, and then diverts to the plurality of airflow outlets 22 for diversion output, so that the airflow output from each air outlet 11 of the air pump 1 is diverted to the plurality of airflow outlets 22 for diversion output after being diverted, and the working efficiency and air supply stability of the air pump 1 are ensured, while the air supply diversion uniformity of the air pump 1 is higher.

[0049] Specifically, the valve seat 2 can be installed on the air pump 1 by means of snap-on or the like, and the air valve 3 is assembled on the valve seat 2 by means of plug-in or the like, and a sealing member is provided at the connection position between the valve seat 2 and the air pump 1, including but not limited to: a rubber ring, a silicone pad, etc., so that the valve seat 2 and the air pump 1 are sealed and connected to avoid the occurrence of air leakage.

[0050] In some preferred embodiments, see Figures 5 to 8 , at least one plug-in slot 21 corresponding to at least one airflow outlet 22 is provided on the valve seat 2. Each plug-in slot 21 is communicated with an airflow outlet 22, for example, each airflow outlet 22 is communicated with the bottom of a plug-in slot 21. The air valve 3 has an air inlet end 31 plugged and matched with the plug-in slot 21, and its air inlet 32 ​​is provided on the air inlet end 31. When the air valve 3 is assembled on the valve seat 2, its air inlet end 31 is plugged into the corresponding plug-in slot 21, and its air inlet 32 ​​is communicated with the corresponding airflow outlet 22, so that the airflow outputted from the airflow outlet 22 directly flows into the corresponding air valve 3 from the air inlet 32 ​​of the corresponding air valve 3.

[0051] It is worth noting that the air inlet end 31 of the air valve 3 and the plug-in groove 21 of the valve seat 2 are sealed and plugged to ensure the plug-in sealing between the air valve 3 and the valve seat 2, wherein the sealing plug-in method includes but is not limited to: interference fit, sealing gasket, sealing ring, glue injection, etc. In some preferred embodiments, the air inlet end 31 and the plug-in groove 21 are sealed and connected in an interference fit manner, that is, the outer wall of the air inlet end 31 of the air valve 3 and the inner wall of the plug-in groove 21 are interference fit.

[0052] In addition, after each gas valve 3 is plugged and assembled with the valve seat 2, a locking member 4 is used to lock and fix it to ensure the installation stability and air tightness between each gas valve 3 and the valve seat 2, and to facilitate the disassembly and assembly of the gas valve 3 on the valve seat 2.

[0053] For details, please refer to Figure 8As shown, the air valve 3 has a first locking portion 33, and the first locking portion 33 is disposed on the air inlet end 31. For example, the first locking portion 33 is disposed around the side wall of the air inlet end 31 of the air valve 3. Figure 5 As shown, the valve seat 2 has a second locking portion 23 corresponding to the first locking portion 33, and the second locking portion 23 is arranged in the notch of the plug-in slot 21. For example, the second locking portion 23 is arranged around the notch of the plug-in slot 21 without blocking the notch of the plug-in slot 21, and the second locking portion 23 can also be provided with an avoidance opening 231, which is connected to the plug-in slot 21, and the avoidance opening 231 is perpendicular to the plug-in direction of the plug-in slot 21, so as to facilitate the connection between the locking member 4 and the second locking portion 23 through the avoidance opening 231.

[0054] When the air valve 3 is plugged into the valve seat 2, the first locking portion 33 corresponds to the second locking portion 23, and the locking member 4 is locked to the first locking portion 33 and the second locking portion 23 from the avoidance opening 231 along a plug-in direction perpendicular to the air valve 3, so that the air valve 3 and the valve seat 2 remain relatively fixed in the plug-in direction.

[0055] It can be understood that the distance between the first locking portion 33 and the end face of the air inlet end 31 should be less than or equal to the depth of the plug-in slot 21 to ensure that when the air inlet end 31 is plugged into the plug-in slot 21, the first locking portion 33 can penetrate into the plug-in slot 21 and can correspond to the second locking portion 23.

[0056] In some embodiments, Figures 5 to 9 As shown, the first locking portion 33 includes a first clamping groove 331, and the second locking portion 23 includes a second clamping groove 232. When the air valve 3 is inserted into the valve seat 2, the notch of the first clamping groove 331 and the notch of the second clamping groove 232 are arranged opposite to each other, so that the first clamping groove 331 and the second clamping groove 232 enclose a cavity, and the cavity is used for inserting the locking member 4. Fig.10 As shown, the locking member 4 includes a clamping block 41 , which is clamped in the first clamping slot 331 and the second clamping slot 232 , wherein the locking member 4 is at least partially inserted into a cavity enclosed by the first clamping slot 331 and the second clamping slot 232 .

[0057] Specifically, after the air valve 3 is plugged into the valve seat 2, the air inlet end 31 of the air valve 3 is plugged into the plug-in groove 21, the first locking portion 33 corresponds to the second locking portion 23, that is, the first clamping groove 331 is aligned with the second clamping groove 232, and the locking member 4 passes through the avoidance opening 231 and is smoothly clamped into the first clamping groove 331 and the second clamping groove 232. Among them, the clamping block 41 of the locking member 4 is clamped into the first clamping groove 331 and the second clamping groove 232, that is, part of the clamping block 41 is clamped into the first clamping groove 331 and part of it is clamped into the corresponding second clamping groove 232, so that the air valve 3 and the valve seat 2 are restricted by the clamping block 41 in the plug-in direction and cannot be relatively displaced, and the air valve 3 and the valve seat 2 are limited in the plug-in direction of the air valve 3.

[0058] In some embodiments, Figures 7 to 9 As shown, the first engaging groove 331 includes a first groove portion 3311 and a second groove portion 3312, and the first groove portion 3311 and the second groove portion 3312 are respectively arranged on the first circumferential side and the second circumferential side of the air valve 3. Specifically, the first circumferential side and the second circumferential side can be two opposite sides of the circumferential direction of the air valve 3, and the first groove portion 3311 and the second groove portion 3312 together enclose the above-mentioned first engaging groove 331, wherein the groove opening of the first engaging groove 331 is perpendicular to the plugging direction of the plugging groove 21.

[0059] like Figure 5 and Figure 6 As shown, the second snap-in slot 232 has a third slot portion 2321 and a fourth slot portion 2322 corresponding to the first slot portion 3311 and the second slot portion 3312 respectively, the third slot portion 2321 and the fourth slot portion 2322 are relatively arranged around the slot opening of the plug-in slot 21, the third slot portion 2321 and the fourth slot portion 2322 are connected to the plug-in avoidance opening 231, the third slot portion 2321 and the fourth slot portion 2322 jointly enclose the above-mentioned second snap-in slot 232, and the slot opening of the second snap-in slot 232 is oriented perpendicular to the plug-in direction of the plug-in slot 21.

[0060] For the above-mentioned locking element 4, please refer to Figures 10 to 12 Combined with Figure 4 The locking member 4 is used to lock and fix each gas valve 3 to the valve seat 2. The locking member 4 includes a clamping block 41, and the clamping block 41 includes a first clamping portion 411, a second clamping portion 412, and a connecting portion 413 connecting the first clamping portion 411 and the second clamping portion 412, wherein the first clamping portion 411 and the second clamping portion 412 are arranged opposite to each other, the first clamping portion 411 is clamped to the first groove portion 3311 and the third groove portion 2321, and the second clamping portion 412 is clamped to the second groove portion 3312 and the fourth groove portion 2322.

[0061] Specifically, Fig.11 , Fig.12 and Figure 4As shown, the connecting portion 413 is located at the avoidance opening 231, the first clamping portion 411 is clamped to the first groove portion 3311 and the third groove portion 2321, a portion of the first clamping portion 411 is located in the first groove portion 3311, and another portion of the first clamping portion 411 is located in the third groove portion 2321; the second clamping portion 412 is clamped to the second groove portion 3312 and the fourth groove portion 2322, a portion of the second clamping portion 412 is located in the second groove portion 3312, and another portion of the second clamping portion 412 is located in the fourth groove portion 2322, so that the first groove portion 3311 and the third groove portion 2321 do not move relative to each other along the plug-in direction of the air valve 3, and the second groove portion 3312 and the fourth groove portion 2322 do not move relative to each other along the plug-in direction of the air valve 3, thereby realizing the fixed connection between the air valve 3 and the valve seat 2.

[0062] The first groove portion 3311 and the second groove portion 3312 are respectively continuously arranged around the first circumference and the second circumference of the air inlet end 31, so as to form a whole wrapped around the side wall of the air inlet end 31. Under this structure, when the air inlet end 31 is inserted into the insertion groove 21, any angle of the notch of the first clamping groove 331 of the air valve 3 can correspond to the second clamping groove 232. When multiple air valves 3 need to be installed on the valve seat 2 at different angles, the design of the first clamping groove 331 of the air valve 3 does not need to consider the change of its angle, which improves the adaptability of the air valve 3 and reduces the cost of separately opening a mold for the air valve 3 due to the design of different installation angles of the air valve 3.

[0063] Moreover, the first clamping groove 331 adopts a setting including a first groove portion 3311 and a second groove portion 3312, and the second clamping groove 232 adopts a setting including a third groove portion 2321 and a fourth groove portion 2322, and the clamping block 41 includes a first clamping portion 411 and a second clamping portion 412, so that the clamping fixation between the air valve 3 and the valve seat 2 is balanced in force, more stable, and the air tightness is enhanced.

[0064] It can be understood that the locking function of the above-mentioned locking component 4 is achieved by relying on the strength of the material of the locking component 4 itself. The higher the strength of the material used in the locking component 4, the stronger its ability to resist damage in the working state. Therefore, the locking component 4 should be made of high-strength and wear-resistant materials, including but not limited to: stainless steel, nickel alloy, aluminum alloy, etc.

[0065] In addition, the shape of the locking member 4 is adapted to the shape of the cavity formed by the first locking portion 33 and the second locking portion 23, so that the locking member 4 effectively limits the first locking portion 33 and the second locking portion 23 along the plugging direction of the air valve 3. The shape of this embodiment is only used as a reference and is not limited to the shape of the first locking portion 33 and the second locking portion 23. Fig.10 The U-shape shown.

[0066] It is worth mentioning that, compared with the traditional snap-fit ​​connection between the air valve 3 and the valve seat 2, the locking structure of the locking component 4, the first locking part 33 of the air valve 3 and the second locking part 23 of the valve seat 2 is more stable and the operation is more convenient. The demand for quick disassembly and assembly of the air valve 3 and the valve seat 2 can be met only by disassembling and assembling the locking component 4 along the groove direction of the avoidance opening 231. Compared with the traditional snap-fit ​​structure, when disassembling and assembling the locking component 4, only the wear of the locking component 4 is involved, and the performance of the air valve 3 and the valve seat 2 is not affected. As a separate component, the locking component 4 only needs to be replaced when it is damaged. Compared with the traditional snap-fit ​​structure that requires replacing the entire air valve 3 or the valve seat 2 when it is damaged, the replacement cost of the locking component 4 is lower and the replacement process is more efficient.

[0067] In some embodiments, please refer to Figure 5 and Figure 6 A pressure regulating channel 25 connected to at least one air flow outlet 22 or at least one socket 24 is provided on the valve seat 2, that is, one end of the pressure regulating channel 25 is connected to at least one air flow outlet 22 or at least one socket 24, and specifically can be connected to the above-mentioned air flow channel for connecting multiple sockets 24, or connected to the above-mentioned branch flow channel connecting multiple air flow outlets 22 and the converging flow channel of multiple sockets 24, and the other end of the pressure regulating channel 25 communicates with the external environment.

[0068] It can be understood that a pressure regulating valve 251 is provided on the pressure regulating channel 25, and the pressure regulating valve 251 is used to control the communication state between the pressure regulating channel 25 and the external environment. When the air pump 1 is in the normal air supply stage, the pressure regulating valve 251 is in a closed state, and the gas generated by the air pump 1 continuously passes through the air valve 3 to enter the external device directly connected to the air valve 3, and the external device includes but is not limited to an air bag, a gas storage container, a gas distribution device, etc.: When the air supply pressure of the external device connected to the air valve 3 exceeds the preset pressure value, the gas pumped into the valve seat 2 by the air pump 1 presents a high-pressure state in the channel formed by the receiving interface 24 and the air flow outlet 22. This high-pressure state is not conducive to the stable connection between the air valve 3 and the external device or the normal operation of the external device. At this time, the pressure regulating valve 251 can be opened to release the high-pressure gas in the valve seat 2 to ensure the normal and stable operation of the air valve 3 and the external device.

[0069] In some embodiments, Figure 1As shown, the gas source device 1000 is provided with a check valve 5, which is arranged between the air inlet 32 ​​of the air valve 3 and the air flow outlet 22 of the valve seat 2, and is used to prevent the gas in the air valve 3 from flowing back into the valve seat 2, that is, to prevent the gas in the air valve 3 from entering the receiving interface 24 after passing through the air inlet 32 ​​and the air flow outlet 22 of the valve seat 2, so as to ensure the unidirectional flow of the air flow. Specifically, the check valve 5 is arranged at the bottom of the slot 21 of the valve seat 2, and when the air valve 3 is plugged into the valve seat 2, the end of the air inlet end 31 of the air valve 3 abuts against the surface of the check valve 5 close to the air valve 3, and the valve seat 2 and the air valve 3 jointly clamp the check valve 5 to form a sealed connection, so as to avoid air leakage between the air valve 3 and the check valve 5.

[0070] The air valve 3 can be any air valve, including but not limited to a solenoid valve or a mechanical air valve.

[0071] In some preferred embodiments, see Figures 7 to 9 The gas valve 3 is selected as a solenoid valve, which includes a valve body 34. The valve body 34 is provided with a conduction chamber 341, an air inlet 32, a gas delivery port 342 and an exhaust port 343, and the air inlet 32, the gas delivery port 342 and the exhaust port 343 are connected with the conduction chamber 341. Specifically, the air inlet 32 ​​is arranged at one end of the inner wall of the conduction chamber 341. After the air valve 3 is plugged into the valve seat 2, the air inlet 32 ​​is ventilated and connected with the gas outlet 11 of the air pump 1. The gas delivery port 342 and the exhaust port 343 are respectively arranged at the other end of the inner wall of the conduction chamber 341. The gas delivery port 342 is connected to external equipment, including but not limited to: an air bag, a gas storage device, a gas cylinder, a gas distribution device, etc., and the exhaust port 343 is connected to the external atmospheric environment or the accommodating space of the air pump 1.

[0072] In addition, a valve core 35 is provided in the conduction chamber 341, and a gap is left between the valve core 35 and the inner wall of the conduction chamber 341 to allow the gas to pass through, or a corresponding fluid channel can be provided on the valve core 35 to allow the gas to flow through. A coil 36 is provided on the valve body 34, and a magnetic field will be generated when the coil 36 is energized. The valve core 35 closes the air inlet 32 ​​or the exhaust port 343 under the excitation of the coil 36, wherein the air delivery port 342 and the conduction chamber 341 are not affected by the valve core 35 and present a normalized connected state. Specifically, the gas valve 3 has a gas delivery state in which the valve core 35 closes the exhaust port 343 and connects the air inlet 32 ​​with the gas delivery port 342, and a deflation state in which the valve core 35 closes the air inlet 32 ​​and connects the air delivery port 342 with the exhaust port 343.

[0073] Specifically, when the gas valve 3 is in the deflated state, the valve core 35 closes the gas inlet 32, the exhaust port 343 and the gas delivery port 342 are respectively connected to the conduction chamber 341, and the gas in the valve body 34 can reach the exhaust port 343 through the gas delivery port 342 via the conduction chamber 341, and be discharged to the external atmospheric environment; when the gas valve 3 is in the gas delivery state, the valve core 35 closes the exhaust port 343, the gas inlet 32 ​​and the gas delivery port 342 are respectively connected to the conduction chamber 341, and the gas in the valve body 34 can reach the gas delivery port 342 through the gas inlet 32 ​​via the conduction chamber 341, and flow to the external equipment connected to the gas delivery port 342.

[0074] In some embodiments, the valve core 35 includes at least one of an iron core and a permanent magnetic core. In some preferred embodiments, the valve core 35 is designed with an iron core material as the main body and permanent magnetic materials at both ends of the valve core 35, which not only reduces the high cost of the valve core 35 completely using a permanent magnetic core, but also avoids the problem of insufficient magnetic force of the valve core 35 made of iron core material.

[0075] In some preferred embodiments, when the air valve 3 adopts an iron core as the main body and a valve core 35 made of permanent magnet material at both ends of the iron core, or a valve core 35 made of permanent magnet, compared with the solenoid valve that only uses an iron core to make the valve core 35, the valve core 35 with an iron core as the main body and permanent magnet material at both ends of the iron core, or the valve core 35 made of permanent magnet is more strongly affected by the excitation effect of the coil 36. Therefore, the volume of the coil 36 required to be wound around the valve body 34 of the air valve 3 can be greatly reduced, thereby making the overall air valve 3 more slender, and more air valves 3 can be accommodated in the air source device 1000 of the same volume.

[0076] Specifically, the air valve using the traditional iron core material valve core is subject to the magnetic force problem of the valve core in the working state, and more coils need to be wound to ensure that the air valve can effectively switch the air path, so as to avoid the valve core failing to effectively switch the air path due to insufficient magnetic force under the excitation of the coil. Therefore, this type of air valve is large in size and occupies the limited space in the air source device. The air valve 3 using the permanent magnet valve core 35 is smaller in size, and the air source device 1000 of the same volume can accommodate more air valves 3. For example, the original air source device 1000 can only accommodate two air valves 3. When the air valve 3 adopts the combined valve core 35 or the permanent magnet valve core 35, the air source device 1000 can accommodate three air valves 3. The corresponding valve seat 2 is provided with three plug-in slots 21. The three plug-in slots 21 and the pressure regulating channel 25 are evenly distributed on the top of the valve seat 2, including but not limited to a tic-tac-toe shape or a straight line arrangement. In some preferred embodiments, a tic-tac-toe arrangement is adopted, such as Fig.10As shown, correspondingly, each slot of the plug-in slot 21 is provided with a second locking portion 23, and the direction of the avoidance port 231 of the second locking portion 23 and the port direction of the pressure regulating channel 25 are evenly distributed around the central axis of the valve seat 2, so as to provide sufficient operating space for the disassembly and assembly of the locking component 4 and improve the internal space utilization rate of the air source device 1000.

[0077] It is worth noting that, due to the different application scenarios of the gas source device 1000, the volume of the gas source device 1000 will also have a larger range of choices. Therefore, the above embodiment is only used as an example and is not limited to setting three gas valves 3. The number of gas valves 3 in the gas source device 1000 includes but is not limited to a positive integer greater than or equal to one.

[0078] In some embodiments, please refer to Figures 7 to 9 As shown, the air valve 3 is provided with a reset element 37; the reset element 37 prompts the valve core 35 to normally close the air inlet 32 ​​or normally close the exhaust port 343. Specifically, in the non-powered state, the elastic action of the reset element 37 prompts the valve core 35 to normally close the air inlet 32 ​​or normally close the exhaust port 343. The above-mentioned reset element 37 includes but is not limited to a spring, a spring, etc. The reset element 37 is connected between the valve core 35 and the inner wall of the conduction chamber 341 near one end of the air inlet 32 ​​to prompt the valve core 35 to normally block the exhaust port 343, or the reset element 37 is connected between the valve core 35 and the inner wall of the conduction chamber 341 near one end of the exhaust port 343 to prompt the valve core 35 to normally block the air inlet 32.

[0079] In some preferred embodiments, the reset element 37 is preferably a spring, one end of the spring abuts against one end of the valve core 35, and the other end of the spring abuts against the inner wall of one end of the conduction chamber 341 where the air inlet 32 ​​is set, so that the valve core 35 normally closes the exhaust port 343 under the elastic force of the spring. When the coil 36 is energized, the excitation of the coil 36 causes the valve core 35 to overcome the elastic force of the spring and move closer to the air inlet 32, while making the exhaust port 343 communicate with the conduction chamber 341, that is, the exhaust port 343, the conduction chamber 341 and the air delivery port 342 are connected in sequence. When the coil 36 is de-energized, the valve core 35 can restore the normal closure of the exhaust port 343 under the action of the reset element 37.

[0080] In some embodiments, Figure 1As shown, the gas source device 1000 also includes a circuit board 6, which is arranged on the valve seat 2, and the circuit board 6 is electrically connected to the gas valve 3 to control the inflation and deflation of the gas valve 3. The connection method between the circuit board 6 and the valve seat 2 includes but is not limited to clamping, screwing, gluing, etc. In this embodiment, preferably, the circuit board 6 is clamped on the valve seat 2, and the valve seat 2 is provided with a corresponding clamping groove for clamping and fixing the circuit board 6. Furthermore, an air pump control circuit can also be arranged on the circuit board 6, and the circuit board 6 is electrically connected to the air pump 1 to control the operation of the air pump 1.

[0081] In some embodiments, Figure 1 As shown, the gas source device 1000 also includes a shell 7, which is covered on the gas valve 3, wherein at least one opening corresponding to at least one gas valve 3 is provided on the shell 7 to accommodate the gas delivery port 342 of at least one gas valve 3 to be connected to an external device. In addition, the shell 7 and the valve seat 2 are covered to form a receiving cavity for accommodating the gas valve 3 and the circuit board 6, which protects the gas valve 3 and the circuit board 6 and prevents the gas valve 3 and the circuit board 6 from being damaged by the external environment such as dust and water vapor. It can be understood that the connection method between the shell 7 and the valve seat 2 includes but is not limited to snap-on, glue-on, screw-on, etc. In this embodiment, preferably, a snap-on fixing method is adopted, a snap-on hook is provided on the valve seat 2, and a snap-on portion is provided on the shell 7, and the snap-on hook cooperates with the snap-on portion to realize the connection and fixation between the valve seat 2 and the shell 7.

[0082] It is worth noting that the air source device 1000 includes but is not limited to being applied to one or more of a pneumatic massage system, a pneumatic wing support system, and a pneumatic lumbar support system, and the corresponding pneumatic comfort system includes but is not limited to being installed in the field of intelligent devices such as car seats, massage seats, and airbag beds. When the air source device 1000 is applied to a pneumatic comfort system, the air valve 3 in the air source device 1000 is connected to the air bag or the gas distribution device of the pneumatic comfort system.
