[0001] The present application relates to the technical field of solenoid valves, and in particular to a pressure regulating valve group and an air wave massager. Background Art

[0002] The structure and composition of general domestic and foreign air wave massager products are mainly composed of an air pump, an air guide tube, a pressure valve and several air bag sleeves. The high, medium and low pressure values ​​are set by the pressure valve. After the air pump is used to inflate the sleeve with air through the air guide tube, a certain pressure is formed in each air bag. By inflating or deflating several air bags, a cyclic massage is performed. However, when the air pump supplies air, the air pressure of each air bag cannot be adjusted, which reduces the massage effect. Summary of the invention

[0003] In order to improve the above-mentioned problems, the present application provides a pressure regulating valve group and an air wave massager.

[0004] The present application provides a pressure regulating valve group and an air wave massager adopting the following technical solutions: A pressure regulating valve group comprises a first valve group, a second valve group, an inflation pipe and an intake pipe; the first valve group is composed of a plurality of first solenoid valves, the second valve group is composed of a plurality of second solenoid valves, and the first solenoid valves are connected to the second solenoid valves in a one-to-one correspondence; each of the first solenoid valves is connected to an inflation pipe, and the inflation pipe is connected to an external airbag; the second solenoid valves are each provided with an exhaust end; one end of the intake pipe is connected to an external air pump, and the other end passes through the second valve group and is connected to the second valve group, and the second solenoid valve switches the connection state with the intake pipe; when any airbag reaches the air pressure requirement, the corresponding first solenoid valve closes the inflation pipe, and other airbags continue to be inflated or exhausted; when any airbag needs to be deflated, the corresponding second solenoid valve is closed, and the connection state between the second solenoid valve and the intake pipe is switched to a closed state, and the airbag continues to be deflated. The body releases air through the exhaust end; the first solenoid valve is also provided with a regulating mechanism for regulating the flow rate; the regulating mechanism includes a lower pad, an upper abutment and a sliding member; a circulation cavity is provided in the first solenoid valve, the upper abutment and the lower pad are both installed on the cavity wall in the circulation cavity, and the upper abutment is located near one end of the inflation tube, and the lower pad is located near one end of the second solenoid valve; the upper abutment is provided with an air flow port; the sliding member slides along the circulation cavity and abuts against the lower pad or the upper abutment, and a circulation port is provided on the sliding member, and the diameter of the circulation port is smaller than the diameter of the air flow port; when the sliding member abuts against the upper abutment, the circulation port is connected with the air flow port and the diameter of the air flow port is reduced; the circulation port is opened at the axis center of the sliding member, and a plurality of first diffuse flow holes are also opened on the sliding member.

[0005] By adopting the above technical solution, when any airbag reaches the air pressure requirement, the corresponding first solenoid valve closes the inflation tube, and other airbags continue to be inflated or deflated; when any airbag needs to be deflated, the corresponding second solenoid valve is closed, and the connection state between the second solenoid valve and the air intake pipe is switched to a closed state, and the gas is deflated through the exhaust end. The second solenoid valve is used to independently control the connection state of the closed air intake pipe to facilitate independent deflation, and the first solenoid valve independently controls the inflation state of the airbag to maintain the airbag, so that when the air pump supplies air, it will not affect the deflation and inflation state of each airbag, thereby achieving a better massage effect.

[0006] Optionally, the upper abutment is further provided with a plurality of second diffuser holes; the air flow port is opened at the axis center of the upper abutment, and the second diffuser holes are opened around the air flow hole; when the sliding member abuts against the upper abutment, the first diffuser holes are connected with the second diffuser holes, and the air flow port is connected with the flow port.

[0007] By adopting the above technical solution, the flow of air can flow through two channels, one is the air flow port and the circulation port, and the other is the first diffuser hole and the second diffuser hole. When the upper abutment member abuts against the sliding member, only the circulation port covers the air flow port to change the circulation caliber, and the first diffuser hole and the second diffuser hole continue to circulate air. This method can ensure the stability of the flow of air through the first diffuser hole and the second diffuser hole, and can also slow down the inflation speed by the abutment between the upper abutment member and the sliding member.

[0008] Optionally, a moving magnetic core sliding along the upper abutment is provided on the side of the upper abutment away from the lower cushion, and a third diffuser hole is provided on the moving magnetic core; a plurality of electromagnetic cores are provided on the side of the upper abutment, and the lengths of the plurality of electromagnetic cores extending toward the airflow outlet are different; and the moving magnetic core is magnetically connected to any of the electromagnetic cores.

[0009] By adopting the above technical solution, the extension length of any electromagnetic core toward the air flow port is different. Therefore, when the moving magnetic core slides along the upper abutment and is magnetically connected to any electromagnetic core, the staggered apertures of the third diffuser hole and the second diffuser hole are different, so that the amount of air flowing can be adjusted according to the staggered apertures.

[0010] Optionally, a fixed slide groove is provided on the upper abutment member, and the moving magnetic core moves along the fixed slide groove.

[0011] By adopting the above technical solution, the moving path of the moving magnetic core is limited by the fixed sliding groove, which can prevent the moving magnetic core from moving at will and prevent the moving magnetic core from being affected by excessive airflow and detaching from the upper abutment, thereby achieving the limiting effect.

[0012] Optionally, the upper abutment member is further provided with a guide tube, the other end of which is connected to the lower cushion member; and the sliding member is sleeved on the outer wall of the guide tube.

[0013] By adopting the above technical solution, the guide tube is used to provide guidance for the sliding member, so that the sliding member can move up and down along the guide tube without turning over due to the influence of airflow.

[0014] Optionally, a fixed air duct is opened in the guide tube, and the fixed air duct passes through the lower cushion.

[0015] By adopting the above technical solution, the role of the fixed air duct is to provide a fixed flow rate of airflow, so that the inflation and deflation of the airbag can be carried out stably through the fixed air duct, and the flow rate of the airflow in other flow directions is adjusted by the sliding part or the moving magnetic core.

[0016] Optionally, the lower cushion is connected to the guide tube and disconnected from the connection point with the flow cavity, so that a flow gap is formed between the lower cushion and the flow cavity.

[0017] By adopting the above technical solution, the guide tube is used for connection, thereby freeing the lower cushion and the flow cavity, allowing the gas to flow through the interval space, thereby reducing the obstruction of the lower cushion and improving the stability of gas flow.

[0018] An air wave massager comprises the pressure regulating valve group.

[0019] By adopting the above technical solution, the airbags during massage can be easily and individually controlled to be inflated and deflated by means of the pressure regulating valve group.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. When any airbag reaches the air pressure requirement, the corresponding first solenoid valve closes the inflation tube, and other airbags continue to inflate or exhaust; when any airbag needs to be deflated, the corresponding second solenoid valve is closed, and the connection state between the second solenoid valve and the air intake pipe is switched to a closed state, and the gas is deflated through the exhaust end. The second solenoid valve is used to control the connection state of the closed air intake pipe separately to facilitate separate deflation, and the first solenoid valve controls the inflation state of the airbag separately to maintain the airbag, so that when the air pump supplies air, it does not affect the deflation and inflation state of each airbag, so that the massage effect is better; 2. The airflow passing through the first solenoid valve is controlled by the regulating mechanism so that the inflation speed of the first solenoid valve is controlled to adapt to more massage effects; 3. When the sliding member is located at the lower cushion member, the airflow flows through the plurality of first diffuser holes and the flow port, and then flows through the flow port to be delivered to the inflation tube. When the air pressure is too high, the airflow drives the sliding member to move along the flow cavity to the upper abutment member and abuts against the upper abutment member. The plurality of first diffuser holes are abutted by the upper abutment member and cannot pass the airflow. The inner diameter of the flow port is smaller than the airflow port, so the airflow can only pass through the upper abutment member from the flow port, thereby achieving the effect of regulating the flow rate. 4. The airflow can flow through two channels, one is the airflow port and the circulation port, and the other is the first diffuser hole and the second diffuser hole. When the upper abutment member abuts against the sliding member, only the circulation port covers the airflow port to change the circulation caliber, and the first diffuser hole and the second diffuser hole continue to circulate the airflow. This method can ensure the stability of the airflow through the first diffuser hole and the second diffuser hole, and can also slow down the inflation speed through the abutment between the upper abutment member and the sliding member.

[0023] The following is a detailed description of the embodiments of the present application with reference to the accompanying drawings so that those skilled in the art can easily implement the present application. The present application can be embodied in a variety of different forms and is not limited to the embodiments described herein.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the representation of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] Throughout the specification, when a device is said to be "connected" to another device, this includes not only the case of "direct connection" but also the case of "indirect connection" by placing other elements therebetween. In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0027] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0028] The embodiments of the present application disclose a pressure regulating valve group and an air wave massager.

[0029] A pressure regulating valve group, reference Figure 1 As shown, it includes a first valve group 1, a second valve group 2, a charging pipe 3 and an intake pipe 4; the first valve group 1 is composed of a plurality of first solenoid valves 11, and the second valve group 2 is composed of a plurality of second solenoid valves 21. The first solenoid valves 11 are connected one-to-one with the second solenoid valves 21. In this embodiment, 6 are taken as an example. Six first solenoid valves 11 are provided, and six corresponding second solenoid valves 21 are synchronously provided, and each second solenoid valve 21 is correspondingly connected to a first solenoid valve 11.

[0030] Each first solenoid valve 11 is connected to an inflation tube 3, and the inflation tube 3 is connected to an external airbag. The airbag is used as a power element of the air wave massager, and the massage effect is achieved through the inflation and deflation of the airbag. Therefore, the inflation and deflation of the airbag are provided through the inflation tube 3.

[0031] The second solenoid valve 21 is provided with an exhaust end, and the exhaust end is provided with an exhaust port. When the airbag is deflated, the gas enters the first solenoid valve 11 through the inflation tube 3, then enters the second solenoid valve 21, and finally discharges the gas through the exhaust end to achieve the effect of deflation.

[0032] One end of the intake pipe 4 is externally connected to the air pump 6 , and the other end passes through the second valve group 2 and is connected to the second valve group 2 , that is, each second solenoid valve 21 is connected to the intake pipe 4 , and the opening and closing of the second solenoid valve 21 can switch the connection state with the intake pipe 4 .

[0033] Specifically, when any airbag reaches the air pressure requirement, there is no need to continue to inflate the airbag. The first solenoid valve 11 corresponding to the airbag that reaches the air pressure requirement can close the connection point with the inflation tube 3, so that the airbag is no longer inflated or deflated, but it does not affect the continued inflation or deflation of other airbags; when any airbag needs to be deflated, the corresponding second solenoid valve 21 is closed, and the connection state between the second solenoid valve 21 and the intake pipe 4 is switched to a closed state. The intake pipe 4 cannot continue to transport gas to the airbag through the second solenoid valve 21. At the same time, the gas in the airbag is exhausted through the inflation tube 3 until the air is deflated from the exhaust end of the second solenoid valve 21. The second solenoid valve 21 is used to separately control the connection state of the closed intake pipe 4 to facilitate separate deflation. The first solenoid valve 11 separately controls the inflation state of the airbag to maintain the airbag, so that when the air pump 6 supplies air, it does not affect the deflation and inflation state of each airbag, so that the massage effect is better.

[0034] In some embodiments, reference Figure 2 or Figure 3 As shown, the first solenoid valve 11 is also provided with a regulating mechanism 5 for regulating the flow rate. The regulating mechanism 5 is located in the first solenoid valve 11, so that when the first solenoid valve 11 is inflated, the airflow passing through the first solenoid valve 11 can be controlled by the regulating mechanism 5, so that the inflation speed of the first solenoid valve 11 is controlled, and more massage effects can be adapted. For example, some first solenoid valves 11 have a slow inflation speed, while some first solenoid valves 11 have a fast inflation speed, so that the inflation speeds of the corresponding airbags are different, and different massage effects are achieved according to the inflation or deflation speeds of the airbags, thereby improving the user experience.

[0035] For further reference, Figure 2 or Figure 3As shown, the regulating mechanism 5 includes a lower cushion member 51, an upper abutment member 52 and a sliding member 53; a circulation chamber 12 is provided in the first solenoid valve 11, and the circulation chamber 12 is used for gas circulation. The upper abutment member 52 and the lower cushion member 51 are both installed on the cavity wall in the circulation chamber 12, and the upper abutment member 52 is located near one end of the inflation tube 3, and the lower cushion member 51 is located near one end of the second solenoid valve 21. The upper abutment member 52 can adopt an upper abutment plate, and the lower cushion member 51 can adopt a lower cushion frame or a lower cushion ring. The lower cushion frame can be a cross or a straight cross, so that the lower cushion member 51 is connected to the circulation chamber 12, and the lower cushion member 51 only serves to abut the sliding member 53 and will not block the airflow.

[0036] When inflating, the airflow direction is from the second solenoid valve 21 to the lower cushion 51, then from the lower cushion 51 to the upper abutment 52, and finally from the upper abutment 52 into the inflation tube 3 to inflate the airbag.

[0037] The upper abutment 52 is provided with an air flow opening 521, the sliding member 53 slides along the flow cavity 12 and abuts against the lower cushion member 51 or the upper abutment 52, the sliding member 53 is provided with a flow opening 531, when the sliding member 53 flows along the flow cavity to the upper abutment 52, the air flow opening 521 is docked with the flow opening 531, when the sliding member 53 flows along the flow cavity to the lower cushion member 51, the air flow opening 521 is separated from the flow opening 531, the sliding member 53 can adopt a sliding ring, the flow opening 531 is opened at the axis center of the sliding member 53, and a plurality of first diffuser holes 532 are also opened on the sliding member 53.

[0038] The inner diameter of the flow port 531 is smaller than the inner diameter of the air flow port 521, so that when the sliding member 53 abuts against the upper abutment member 52, the flow port 531 is connected with the air flow port 521, and the air flow port 521 is reduced at the same time. That is, after the flow port 531 is connected with the air flow port 521, the small diameter of the flow port 531 covers the large diameter of the air flow port 521, so that the air flow can only circulate through the small diameter flow port 531, thereby achieving the effect of adjusting the inflation volume per unit time.

[0039] When the sliding member 53 abuts against the upper abutting member 52 , the upper abutting member 52 is pressed against the sliding member 53 , so that the first diffuser holes 532 are covered, and the airflow can only flow through the airflow opening 521 .

[0040] When the sliding member 53 is located on the lower cushion member 51 , the first diffuser holes 532 are not covered, so the airflow can pass through the first diffuser holes 532 and the flow opening 531 , so that the flow rate of the airflow is stable.

[0041] Specifically, when the air intake pipe 4 delivers the gas to the flow chamber 12 of the first solenoid valve 11 through the second solenoid valve 21, the airflow is blocked by the sliding member 53. When the air pressure is sufficient to lift the sliding member 53, the airflow drives the sliding member 53 to move toward the flow chamber 12 until it abuts against the upper abutment 52. When the sliding member 53 abuts against the upper abutment, the airflow can only pass through the airflow port 521 from the flow port 531 with a smaller diameter, thereby reducing the inflation speed and restricting the flow of the airflow, thereby achieving the effect of regulating the inflation speed.

[0042] When the air pressure is insufficient to push the sliding member 53 to abut against the upper abutting member 52 or the air is deflated, the sliding member 53 abuts against the lower cushion member 51 , and the airflow can pass through the first diffuser holes 532 and the flow port 531 , so that the airflow is not affected and flows normally.

[0043] Further, refer to Figure 3 or Figure 4 As shown, the upper abutment 52 is further provided with a plurality of second diffuser holes 522, the aperture of the second diffuser holes 522 is consistent with the aperture of the first diffuser holes 532, the air flow opening 521 is opened at the axis of the upper abutment 52, and the second diffuser holes 522 are opened around the air flow hole. When the sliding member 53 abuts against the upper abutment 52, the first diffuser holes 532 are communicated with the second diffuser holes 522, and the air flow opening 521 is communicated with the flow opening 531.

[0044] The airflow can flow through two channels, one is the airflow port 521 and the circulation port 531, and the other is the first diffuser hole 532 and the second diffuser hole 522. When the upper abutment 52 abuts against the sliding member 53, only the circulation port 531 covers the airflow port 521 to change the diameter of the circulation port 531, and the first diffuser hole 532 and the second diffuser hole 522 continue to circulate the airflow. This method can ensure the stable circulation of the airflow and slow down the inflation speed through the abutment between the upper abutment 52 and the sliding member 53.

[0045] In some embodiments, reference Figure 4 As shown, a moving magnetic core 54 sliding along the upper abutment 52 is provided on the side of the upper abutment 52 away from the lower cushion 51, and a third diffuser hole 541 is provided on the moving magnetic core 54. The aperture of the third diffuser hole 541 can be the same as the aperture of the second diffuser hole 522 or the first diffuser hole 532. A plurality of electromagnetic cores 55 are provided on the side of the upper abutment 52. The lengths of the plurality of electromagnetic cores 55 extending toward the air flow outlet 521 are different. The moving magnetic core 54 is magnetically connected to any electromagnetic core 55. When the electromagnetic core 55 is energized, a magnetic force is generated. The moving magnetic core 54 is affected by the magnetic force of any electromagnetic core 55 and moves along the upper abutment 52 to the energized electromagnetic core 55, so that the third diffuser hole 541 is staggered with the second diffuser hole 522 and covers the second diffuser hole 522, thereby achieving the effect of adjusting the aperture of the second diffuser hole 522.

[0046] The extension length of any electromagnetic core 55 toward the air flow port 521 is different. Therefore, when the moving magnetic core 54 slides along the upper abutment 52 and is magnetically connected to any electromagnetic core 55, the staggered apertures of the third diffuser hole 541 and the second diffuser hole 522 are different, so that the amount of air flowing can be adjusted according to the staggered apertures.

[0047] For further reference, Figure 5 As shown, a fixed groove 523 is provided on the upper abutment 52, and the moving magnetic core 54 moves along the fixed groove 523. The style of the fixed groove 523 is determined according to the number of the electromagnetic cores 55. For example, when there are two electromagnetic cores 55, the path style of the fixed groove 523 is a straight path, and the two ends of the straight path correspond to two electromagnetic cores 55 respectively. If there are three electromagnetic cores 55, the path style of the fixed groove 523 is a triangular path. The moving path of the moving magnetic core 54 is limited by the fixed groove 523, which can prevent the moving magnetic core 54 from moving at will and prevent the moving magnetic core 54 from being affected by excessive airflow and detaching from the upper abutment 52, thereby achieving the role of limiting.

[0048] In this embodiment, two electromagnetic cores 55 are used as an example, so the path pattern of the fixed slide rail is a straight path. Figure 5 shown.

[0049] Furthermore, the moving magnetic core 54 is also provided with a movable port opposite to the air flow port 521. When the moving magnetic core 54 moves along the fixed slide groove 523, the position of the movable port can be staggered with the air flow port 521, thereby changing the diameter of the air flow port 521, thereby further adjusting the gas flow.

[0050] Wherein, when the electromagnetic core 55 and the moving magnetic core 54 are provided, the sliding member 53 may not be provided, and the airflow may be adjusted by providing the sliding member 53 through the flow port 531 and the airflow port 521, and further adjustment may be provided, and whether to provide it may be determined according to demand.

[0051] In some embodiments, reference Figure 6 As shown, the upper abutment 52 is further provided with a guide tube 524, and the other end of the guide tube 524 is connected to the lower cushion 51; the sliding member 53 is sleeved on the outer wall of the guide tube 524, and there are two ways of sleeved, one is that it can penetrate the guide tube 524 through the flow port 531, and the other is that it penetrates the guide tube 524 through any first diffuser hole 532. The guide tube 524 is used to provide guidance for the sliding member 53, so that the sliding member 53 can move up and down along the guide tube 524 without turning over due to the influence of airflow.

[0052] Among them, a limiting protrusion is provided on the surface of the guide tube 524, and a limiting groove is provided in the sliding member 53. When the guide tube 524 is inserted into the sliding member 53, the limiting protrusion is located in the limiting groove. The limiting protrusion and the limiting groove are used to further fix the moving trajectory of the sliding member 53, thereby improving the sliding stability of the sliding member 53.

[0053] Furthermore, a fixed air duct is opened in the guide tube 524, and the fixed air duct runs through the lower cushion 51. The function of the fixed air duct is to provide a fixed flow rate of airflow, so that the inflation and deflation of the airbag can be carried out stably through the fixed air duct, and then the flow rate of the airflow in other flow directions is adjusted by the sliding part 53 or the moving magnetic core 54.

[0054] Furthermore, the lower pad 51 is connected to the guide tube 524 and the connection point with the circulation chamber 12 is disconnected, so that a circulation gap is formed between the lower pad 51 and the circulation chamber 12. This method allows the lower pad 51 to no longer be connected through the inner wall of the circulation chamber 12, but to be connected through the guide tube 524, thereby freeing up the lower pad 51 and the circulation chamber 12, allowing gas to flow through the gap space, thereby reducing the obstruction of the lower pad 51 and improving the stability of gas circulation.

[0055] The present application also provides an air wave massager, referring to Figure 7 As shown, it includes the pressure regulating valve group in any of the above embodiments. As shown in the reference figure, the pressure regulating valve group is connected to an air pump 6 and a connecting pipe.

[0056] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
