The gas distribution device is ventilatedly connected to the air source device and the air bag respectively. The gas distribution device is provided with an air valve, which is connected to the air bag. The air valve is used to control the inflation and deflation of the air bag. When the air valve is in an inflated state, the air source device can be controlled to inflate the air bag. When the air valve is in a deflated state, the air source device is not connected to the air bag, and the air valve discharges the gas from the air bag.

[0043] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification and in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0044] The pneumatic massage system 100 provided in the embodiment of the present invention is shown in FIG. Figure 1-2 As shown, it includes an air valve 10, a pressure regulating valve 20, an air bag 50, an air source device 60 and a controller.

[0045] The air bag 50 is ventilated and connected to the air source device 60 through the air valve 10. During operation, the air source device 60 supplies air to inflate the air bag 50 to expand the air bag 50 and achieve squeezing massage. The air valve 10 is used to control the on-off of the air flow from the air source device 60 to the air bag 50. The pressure regulating valve 20 is ventilated and connected to the air valve 10. When the air valve 10 is in an open state, the pressure regulating valve 20 can discharge the gas in the air bag 50 when it is opened, so that the air bag 50 is deflated and contracted.

[0046] In a feasible embodiment, the air source device 60 may be, but is not limited to, an air pump or an air compressor, or a container with a preset air pressure value, such as a high-pressure gas storage tank.

[0047] In a feasible embodiment, the gas valve 10 may be, but is not limited to, a solenoid valve or a fluid vibrator, such as a two-position three-way solenoid valve or a three-position three-way solenoid valve.

[0048] For specific preferred embodiments, please refer to Figure 3As shown, a gas valve 10 is adopted as a two-position three-way gas valve. The gas valve 10 includes a valve body 11, a valve core 12 and a coil 13. Among them, a conduction chamber 11a and an air inlet 11b, an air charging port 11c and an air discharge port 11d connected to the conduction chamber 11a are provided in the valve body 11. The air inlet 11b is ventilated and connected to the gas source device 60, and the air charging port 11c is ventilated and connected to the air bag 50; the valve core 12 is arranged in the conduction chamber 11a, and the coil 13 is wound around the valve body 11. When the coil 13 is energized, the valve core 12 moves to block the air inlet 11b or the air discharge port 11d under the excitation of the coil 13. The gas valve 10 has an open state in which the valve core 12 blocks the air discharge port 11d and connects the air inlet 11b with the air charging port 11c, and a closed state in which the valve core 12 blocks the air inlet 11b and connects the air charging port 11c with the air discharge port 11d.

[0049] When the air valve 10 is in an open state, the gas of the air source device 60 can enter the inflation chamber of the air bag 50 through the air inlet 11b, the conduction chamber 11a, and the inflation port 11c in sequence to supply air to the air bag 50, so that the air bag 50 is inflated. When the air valve 10 is in a closed state, the air inlet 11b of the air valve 10 is blocked, and the gas of the air source device 60 cannot flow into the air bag 50 through the air inlet 11b, and the air source device 60 stops supplying air to the air bag 50; and further, the gas in the air bag 50 can be discharged to the outside through the inflation port 11c, the conduction chamber 11a, and the air release port 11d in sequence.

[0050] The inflation port 11c of the air valve 10 can be connected to the air bag 50 through an air pipe, and the air inlet 11b can be connected to the air source device 60 through another air pipe. Preferably, the air valve 10 is provided with an inflation nozzle 14 connected to the inflation port 11c, so as to realize a convenient ventilation connection with the air pipe connected to the air bag 50. Correspondingly, the air inlet 11b can also be provided with an air inlet nozzle 33 similar to the inflation nozzle 14, so as to be connected to the air pipe connected to the air source device 60.

[0051] In a feasible embodiment, the pressure regulating valve 20 may be, but is not limited to, a mechanical pressure regulating valve or an electromagnetic pressure regulating valve, and is preferably a pressure regulating valve with a controllable pressure regulating stroke.

[0052] For specific preferred embodiments, please refer to Figure 4As shown, the pressure regulating valve 20 is an electromagnetic pressure regulating valve, which includes a pressure regulating valve body 21, a pressure regulating valve core 22 and a pressure regulating coil 23. The pressure regulating coil 23 is wound around the pressure regulating valve body 21, and the pressure regulating valve body 21 is provided with a pressure regulating channel 21a and an air inlet 21b and a pressure relief hole 21c connected to the pressure regulating channel 21a. The pressure regulating valve core 22 is arranged in the pressure regulating channel 21a, and the air inlet 21b is ventilated and connected to the air inlet 11b of the air valve 10, and the pressure relief hole 21c of the pressure regulating valve 20 is connected to the atmosphere. When the pressure regulating coil 23 is energized, the pressure regulating coil 23 will drive the pressure regulating valve core 22 to move to close the air inlet 21b or open the air inlet 21b by excitation. By controlling the power supply of the voltage regulating coil 23, the pressure regulating valve 20 has a closed state in which the pressure regulating valve core 22 blocks the air inlet hole 21b, and an open state in which the pressure regulating valve core 22 opens the air inlet hole 21b and connects the air inlet hole 21b with the pressure relief hole 21c.

[0053] When the pneumatic massage system of the embodiment of the present invention is working, the air valve 10 is in the open state, and the air inlet 21b of the pressure regulating valve 20 is ventilated and connected to the air bag 50 through the air inlet 11b, the conduction chamber 11a and the inflation port 11c of the air valve 10 in sequence. When the pressure regulating valve core 22 of the pressure regulating valve 20 is controlled to move and open the air inlet 21b, the air bag 50 is connected to the atmosphere through the pressure relief hole 21c connected to the air inlet 21b, so that the gas in the air bag 50 is depressurized and discharged to the atmosphere.

[0054] The controller is communicatively connected to the gas valve 10, the pressure regulating valve 20 and the gas source device 60, and is used to control the operation of the gas valve 10, the pressure regulating valve 20 and the gas source device 60, such as controlling the gas valve 10 to open or close, controlling the pressure regulating valve 20 to open or close, and controlling the gas source device 60 to supply or stop supplying gas.

[0055] The controller is configured to at least execute a first voltage regulation step S1 and a second voltage regulation step S2, and the first voltage regulation step S1 and the second voltage regulation step S2 are executed alternately.

[0056] Specifically, the first pressure regulating step S1 includes: controlling the air valve 10 to open, and controlling the pressure regulating valve 20 to open, so as to guide the gas in the air bag 50 to be discharged through the pressure regulating valve 20, so that the air pressure in the air bag 50 drops from the first air pressure value to the second air pressure value; the second pressure regulating step S2 includes: controlling the air valve 10 to open, controlling the air source device 60 to inflate the air bag 50, and controlling the pressure regulating valve 20 to close, so that the air pressure in the air bag 50 rises from the second air pressure value to the first air pressure value.

[0057] Wherein, the first air pressure value is greater than the second air pressure value. In a specific feasible embodiment, relative to the atmospheric pressure value, the first air pressure value is greater than or equal to 35KPa, and the second air pressure value is greater than or equal to 20KPa. When the air pressure in the airbag 50 is at the first air pressure value, the airbag 50 is relatively inflated to achieve a squeeze massage, and when the air pressure in the airbag 50 is at the second air pressure value, the airbag 50 is relatively deflated and contracted. The controller alternately executes the first pressure regulating step S1 and the second pressure regulating step S2, so that the air pressure in the airbag 50 alternates between the first air pressure value and the second air pressure value, and the airbag 50 is repeatedly inflated and expanded to achieve a vibration massage effect.

[0058] The controller alternately performs the first pressure regulating step S1 and the second pressure regulating step S2, specifically by controlling the repeated opening and closing of the pressure regulating valve 20. Therefore, the control of the repeated opening and closing frequency of the pressure regulating valve 20 realizes the regulation of the repeated inflation frequency of the air bag 50, and then realizes the regulation of the vibration massage frequency, which facilitates the control of the vibration massage.

[0059] In the pneumatic massage system of the embodiment of the present invention, before the operation starts, the air bag 50 is usually in a deflated state, and the air pressure in the air bag 50 is close to the atmospheric pressure. For example, before the operation starts, the air valve 10 is in a closed state, and the air bag 50 is connected to the atmosphere through the inflation port 11c, the conduction chamber 11a, and the deflation port 11d of the air valve 10, and the internal air pressure is equal to the atmospheric pressure.

[0060] In some embodiments, the controller is also used to execute a pre-filling step S0, which includes: controlling the air valve 10 to open, controlling the air source device 60 to inflate the air bag 50, and controlling the pressure regulating valve 20 to close, so that the air pressure in the air bag 50 rises from the third air pressure value to the first air pressure value.

[0061] The third air pressure value is smaller than the first air pressure value and smaller than the second air pressure value. Preferably, the third air pressure value is equal to or close to the atmospheric pressure value.

[0062] When the pneumatic massage system of the embodiment of the present invention performs vibration massage, after the controller completes the pre-charging step S0, it alternately performs the first pressure regulating step S1 and the second pressure regulating step S2.

[0063] In a feasible embodiment, the controller includes at least one processor and a memory in communication with the at least one processor. The memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the pre-charging step S0, the first pressure regulating step S1, and the second pressure regulating step S2 to achieve vibration massage of the air bag 50.

[0064] Moreover, at least the part of the controller used to control the gas valve 10 and the pressure regulating valve 20 can usually be integrated on the circuit board 40 that supplies power to the gas valve 10 and / or the pressure regulating valve 20, so as to facilitate the power supply of the controller and its control of the gas valve 10 and the pressure regulating valve 20. The part of the controller used to control the gas source device 60 can usually be integrated on the circuit board that supplies power to the gas source device 60.

[0065] In some embodiments, the pneumatic massage system of the present invention is described in detail. Figure 5 As shown in FIG. 1 , the air bag 50 can be provided as more than one, and the multiple air bags 50 are provided in parallel to perform the squeezing and massaging functions independently. Alternatively, please refer to Figure 6 As shown, the air bags 50 are arranged in multiple groups, such as two groups, and the multiple groups are arranged in parallel. Each group of air bags 50 is arranged in multiple groups with more than one air bag. The multiple air bags 50 in the same group are arranged in parallel, and perform squeezing and massaging functions independently. Among them, each air bag 50 is controlled by an air valve 10 to be ventilated with the air source device 60, and a single air source device 60 supplies air to multiple air bags 50. The controller is connected to the multiple air valves 10 for communication and controls each air valve 10 to work independently, and the pressure regulating valve 20 is connected to the multiple air valves 10 for ventilation in series.

[0066] Preferably, see Figure 7 As shown, multiple air valves 10 corresponding to multiple air bags 50 can be modularly integrated. In the specific embodiment shown, the air valve 10 can be provided with an air intake seat connected to the air inlet 11b of the valve body 11, and the air intake seats of the multiple air valves 10 are ventilated in series. The multiple air valves 10 connected in series are then connected in series to an air intake pipe 30, and are uniformly ventilated and connected to the air source device 60 through the air intake pipe 30, so as to facilitate the unified air intake management of the multiple air valves 10. When the air bags 50 are arranged in multiple groups, the multiple groups of air valves 10 corresponding to the multiple groups of air bags 50 are respectively connected in series to the air intake pipe 30 after being ventilated in series, and the multiple groups of air valves 10 are arranged in parallel. Among them, the air intake pipe 30 can be provided with an air intake nozzle 33 for ventilating and connecting to the air pipe connected to the air source device 60. Moreover, the multiple air valves 10 are specifically electrically connected to the same circuit board 40, so as to improve the modular integration, and ensure the relative position between the air valves 10 to avoid series leakage. The controller may be integrated on the circuit board 40 .

[0067] When the pneumatic massage system with multiple air bags 50 and air valves 10 corresponding to the multiple air bags 50 are modularly integrated and arranged, the controller only needs to control the air valves 10 corresponding to the air bags 50 that need to be repeatedly inflated to achieve vibration massage to be in an open state, and control the pressure regulating valve 20 to be repeatedly opened and closed, without simultaneously controlling the multiple air valves 10 corresponding to the multiple air bags 50 to be repeatedly opened and closed. This reduces the difficulty and complexity of controlling the vibration massage of the multiple air bags 50 at the same time, and reduces the noise generated by the frequent operation of the multiple air valves 10.

[0068] During the vibration massage pressure regulation process in which the controller alternately executes the first pressure regulation step S1 and the second pressure regulation step S2, when the controller executes the first pressure regulation step S1, the air source device 60 can be controlled to maintain the air supply state or to stop the air supply state. The air bag 50 can be repeatedly inflated and expanded only by controlling the opening and closing of the pressure regulating valve 20 to achieve a vibration massage effect.

[0069] For example, in some embodiments, when the controller performs the first pressure regulating step S1 , the controller controls the gas source device 60 to keep supplying gas to the air bag 50 . When the controller performs the second pressure regulating step S2 , the controller controls the gas source device 60 to keep supplying gas to the air bag 50 .

[0070] Alternatively, in some other embodiments, when the controller performs the first pressure regulating step S1 , the controller controls the gas source device 60 to stop supplying gas to the air bag 50 . When the controller performs the second pressure regulating step S2 , the controller controls the gas source device 60 to keep supplying gas to the air bag 50 .

[0071] The embodiment of the present invention further provides a massage device, which can be a seat, a seat cover or a mattress, etc. The massage device includes the above-mentioned pneumatic massage system 100. The specific structure and function of the pneumatic massage system 100 can be referred to the above-mentioned embodiment, and will not be described in detail here.

[0072] The embodiment of the present invention also provides a pneumatic massage method, which is applied to the pneumatic massage system 100. Figure 8 , the pneumatic massage method comprises:

[0073] The controller performs the first voltage regulation step S1 and the second voltage regulation step S2 alternately.

[0074] The first pressure regulating step S1 includes: controlling the air valve 10 to open, and controlling the pressure regulating valve 20 to open, so as to guide the gas in the air bag 50 to be discharged through the pressure regulating valve 20, so that the air pressure in the air bag 50 drops from the first pressure value to the second pressure value.

[0075] During the execution of the first pressure regulating step S1, the air valve 10 is controlled to open, and the gas in the air bag 50 is guided to the pressure regulating valve 20 through the inflation port 11c, the conduction chamber 11a, and the air inlet 11b of the air valve 10. When the pressure regulating valve 20 is opened, the gas is guided to be discharged to the atmosphere through the air inlet hole 21b, the pressure regulating channel 21a, and the pressure relief hole 21c of the pressure regulating valve 20, so that the air bag 50 is deflated and the pressure is reduced.

[0076] The first air pressure value is greater than the second air pressure value. In some embodiments, relative to the atmospheric pressure value, the first air pressure value is greater than or equal to 35KPa, for example: 36KPa, 50KPa, 60KPa, etc. In other embodiments, relative to the atmospheric pressure value, the second air pressure value is greater than or equal to 20KPa, for example: 21KPa, 25KPa, 28KPa, 30KPa, etc.

[0077] The time interval for the air pressure in the airbag 50 to drop from the first pressure value to the second pressure value, that is, the duration of executing the first pressure adjustment step S1, is maintained at a first preset time, for example: 80 milliseconds, 95 milliseconds, 100 milliseconds, 200 milliseconds.

[0078] In a unit time, the gas flow rate of the gas in the air bag 50 discharged to the outside through the pressure regulating valve 20 is kept constant. Of course, in some embodiments, the gas flow rate of the gas in the air bag 50 discharged to the outside through the pressure regulating valve 20 is gradually reduced.

[0079] During the execution of the first pressure regulating step S1 , the gas source device 60 can be controlled to maintain the gas supply state or to stop the gas supply state, and the repeated inflation of the air bag 50 can be achieved only by controlling the opening and closing of the regulating valve 20 .

[0080] When the air source device 60 is controlled to maintain the air supply state and the pressure regulating valve 20 is opened, the amount of gas input by the air source device 60 to the air bag 50 per unit time is less than the amount of gas discharged from the outside by the pressure regulating valve 20, so that the air pressure in the air bag 50 decreases. Among them, the difference between the amount of gas exhausted by the pressure regulating valve 20 per unit time and the amount of gas inflated into the air bag 50 by the air source device 60 per unit time will affect the time length from the first air pressure value to the second air pressure value. Therefore, the difference can be set according to the actual required time length. For example, when it is necessary to quickly reduce the first air pressure value to the second air pressure value, the amount of gas exhausted by the pressure regulating valve 20 per unit time can be increased to increase the difference, or the amount of gas inflated into the air bag 50 by the air source device 60 per unit time can be reduced to increase the difference. Of course, in some embodiments, multiple differences can also be set, and the user is allowed to select the difference. When the user selects different differences, the time length from the first air pressure value to the second air pressure value is also different.

[0081] When the control gas source device 60 is in a state of stopping gas supply, that is, the pressure regulating valve 20 is open, the amount of gas input by the gas source device 60 to the air bag 50 per unit time is zero or close to zero, which is obviously less than the amount of gas discharged from the pressure regulating valve 20 to the outside, causing the air pressure in the air bag 50 to drop.

[0082] The second pressure regulating step S2 includes: controlling the air valve 10 to open, controlling the air source device 60 to inflate the air bag 50, and controlling the pressure regulating valve 20 to close, so that the air pressure in the air bag 50 increases from the second air pressure value to the first air pressure value.

[0083] When the air valve 10 is opened and the pressure regulating valve 20 is controlled to be closed, the air source device 60 is controlled to continuously inflate the air bag 50, and the air pressure of the air bag 50 will gradually increase. The time it takes for the air pressure in the air bag 50 to rise from the second air pressure value to the first air pressure value depends on the amount of gas inflated into the air bag by the air source device 60 per unit time. Therefore, the amount of gas inflated by the air source device 60 per unit time can be set according to the actual required time.

[0084] In some embodiments, the time interval for the air pressure in the airbag 50 to rise from the second air pressure value to the first air pressure value, that is, the execution duration of the second pressure adjustment step S2, is maintained at a second preset time, for example: 80 milliseconds, 95 milliseconds, 100 milliseconds, 200 milliseconds, etc.

[0085] In the pneumatic massage method of the embodiment of the present invention, when the first pressure regulating step S1 is executed, the pressure regulating valve 20 is opened, and the gas in the air bag 50 is discharged through the pressure regulating valve 20, so that the air pressure in the air bag 50 decreases. When the first pressure regulating step S2 is executed, the air valve 10 is controlled to be opened, and the pressure regulating valve 20 is closed, and the air source device 60 inflates the air bag 50, and the air pressure in the air bag 50 increases. When the first pressure regulating step S1 and the second pressure regulating step S2 are alternately executed, the air bag 50 can be alternately executed to exhaust and shrink and to inflate, so that the air bag 50 provides Beating vibration massage effect; in addition, in the first pressure regulating step S1 and the second pressure regulating step S2, the air valve 10 is in the open state, and the air source device 60 can be in the air supply or stop supply state, and only the pressure regulating valve 20 is controlled alone to realize the switching of inflation and deflation of the air bag 50, that is: only by controlling the pressure regulating valve 20, the inflation and deflation of the air bag 50 can be switched, and the beating vibration massage effect is achieved. The control logic is simple, which reduces the control difficulty and complexity of the vibration massage, and reduces the noise generated by the frequent operation of multiple air valves.

[0086] Before starting to alternately execute the first pressure regulating step S1 and the second pressure regulating step S2 , the air bag 50 is usually in a deflated state, and the air pressure in the air bag 50 is close to the atmospheric pressure value.

[0087] Therefore, the pneumatic massage method of the embodiment of the present invention further includes performing a pre-charging step S0. The pre-charging step S0 includes:

[0088] The air valve 10 is controlled to open so that the air source device 60 inflates the air bag 50, and the pressure regulating valve 20 is controlled to close so that the air pressure in the air bag 50 increases from the third air pressure value to the first air pressure value.

[0089] The third air pressure value is smaller than the first air pressure value and the second air pressure value. For example, the third air pressure value is an atmospheric pressure value or a value close to the atmospheric pressure value, such as 0KPa, 3KPa, and so on.

[0090] In addition, the time interval from the third air pressure value changing to the first air pressure value, that is, the duration of executing the pre-charging step S0, is maintained at a third preset time, for example: 2000 milliseconds, 2500 milliseconds, 2800 milliseconds, 3000 milliseconds.

[0091] It is worth noting that, in some embodiments, after the alternating execution of the first pressure regulating step S1 and the second pressure regulating step S2 is completed, that is, after stopping the control of the first pressure regulating step S1 and the second pressure regulating step S2, the air pressure value in the air bag 50 can also be controlled to remain at the first air pressure value or the second air pressure value within a short pause period, and the air pressure value in the air bag 50 is not adjusted to a range that deviates from the first air pressure value to the second air pressure value. In this way, when the alternating execution of the first pressure regulating step S1 and the second pressure regulating step S2 is started next time after a short pause, it can be started directly without waiting for the air pressure in the air bag to recover to the first air pressure value or the second air pressure value before alternatingly executing the first pressure regulating step S1 and the second pressure regulating step S2, thereby realizing quick start and vibration of the pneumatic massage system 100.

[0092] In order to better understand and illustrate the pneumatic massage method of the embodiment of the present invention, the first air pressure value is selected to be 35KPa, the second air pressure value is 20KPa, the third air pressure value is 0KPa, the first preset time is 80 milliseconds, the second preset time is 100 milliseconds, and the third preset time is 2800 milliseconds to execute the pneumatic massage method of the embodiment of the present invention.

[0093] The controller first performs a pre-filling step S0, including: controlling the air valve 10 to open so that the air source device 60 inflates the air bag 50, and controlling the pressure regulating valve 20 to close so that the air pressure in the air bag 50 increases from the third air pressure value to the first air pressure value.

[0094] Then, the controller starts to alternately perform the first pressure regulating step S1 and the second pressure regulating step S2. The first pressure regulating step S1 includes: controlling the air valve 10 to open, and controlling the pressure regulating valve 20 to open, so as to guide the gas in the air bag 50 to be discharged through the pressure regulating valve 20, so that the air pressure in the air bag 50 drops from the first pressure value to the second pressure value. The second pressure regulating step S2 includes: controlling the air valve 10 to open, controlling the air source device 60 to inflate the air bag 50, and controlling the pressure regulating valve 20 to close, so that the air pressure in the air bag 50 rises from the second pressure value to the first pressure value.

[0095] After executing the pre-charging step S0 and alternately executing the first pressure regulating step S1 and the second pressure regulating step S2, the pressure variation curve in the air bag 50 is obtained as shown in FIG. Fig. 9 When the internal air pressure of the air bag 50 reaches the first air pressure value each time, a corresponding squeezing massage is realized, and when the air bag 50 repeatedly reaches the first air pressure value at a high frequency, the air is repeatedly inflated at a high frequency, thereby achieving a vibration massage effect of repeated beating.
