Description

Technical Field

[0001] This utility model relates to the field of massage technology, and in particular to a pneumatic comfort system and massage device. Background Technology

[0002] Pneumatic comfort massage systems, as devices applied in the massage field, rely on internal air bags to change air pressure, thereby achieving different levels of pressure on corresponding parts of the body to achieve a massage effect. With the diversification of massage modes, the internal structure of pneumatic comfort systems has gradually become more complex, and the number of key components enabling massage functions, such as air bags and control valves, has surged. The control devices in pneumatic comfort systems need to work in conjunction with the air bags to achieve various massage modes.

[0003] In the process of developing this utility model, the inventors discovered that current pneumatic comfort systems include an air source, multiple air bags, and a control device. The control device includes a control valve and a circuit board. The air source is connected to multiple air bags through the control valve, which controls the flow between the air source and the air bags. The circuit board is electrically connected to the control valve to control it. To achieve the current variety of massage modes, pneumatic comfort systems commonly employ a one-to-one control scheme between the control valve and each air bag. This results in a surge in the number of control valves, leading to a significant increase in the size of the control device and increased manufacturing costs. Furthermore, due to limitations in the gas output flow rate of the air source, most massage methods actually only control the inflation and deflation of a single air bag at a specific location at any given time. In this case, other solenoid valves are not actually in operation. The extensive use of solenoid valves in existing technologies leads to high manufacturing costs for the entire pneumatic comfort system, which in turn affects subsequent maintenance costs and hinders the application of pneumatic comfort systems in massage chairs, massage beds, and other fields. Utility Model Content

[0004] This utility model provides a pneumatic comfort system, massage equipment, massage method, and cyclic massage method. The main technical problem it solves is that the excessive number of control valves in existing start-up comfort systems leads to high manufacturing costs for equipment such as seats that use start-up comfort systems.

[0005] To solve the above-mentioned technical problems, the present invention provides a pneumatic comfort system, comprising: an air source; an air guiding assembly and an air bag assembly; the air guiding assembly includes a driving member and a sliding member, the driving member being connected to the sliding member, the driving member driving the sliding member to move along a preset direction, the sliding member being provided with a first gas channel, one end of the first gas channel being connected to the air source and the other end being provided with an inflation port; the air bag assembly includes a plurality of air bags disposed on the moving path of the sliding member, each air bag including an abutment portion and an inflatable deformable portion. The bag body is disposed at the abutment portion, and the abutment portion is provided with a second gas channel. One end of the second gas channel is connected to the bag body, and the other end is provided with an abutment port that matches the inflation interface. When the sliding member abuts and holds against the abutment portion of any of the air bags, the inflation interface is connected to the abutment port, and the gas source is connected to the corresponding bag body through the first gas channel and the second gas channel. When the sliding member is misaligned with the abutment portion of the air bag, the inflation interface is misaligned with the abutment port, and the bag body is disconnected from the gas source.

[0006] Optionally, there are multiple air bags, which are spaced apart from each other; the driving member is used to drive the sliding member to move along a preset direction to adjust the air bag docked with the sliding member.

[0007] Optionally, the end face of the slider near the air bag is an arc-shaped surface, and the inflation port is located at the top of the arc-shaped surface.

[0008] Optionally, the top of the arc-shaped surface is provided with a groove, and the inflation port is disposed at the bottom of the groove; when the sliding member abuts against the abutting part, the abutting part is partially received in the groove, and the abutting port is connected to the inflation port.

[0009] Optionally, the gas guiding assembly further includes a control valve disposed within the second gas passage, the control valve being used to control the opening and closing of the second gas passage.

[0010] Optionally, the air guiding assembly further includes a mounting member, which is provided with a sliding cavity and a plurality of mounting holes. The sliding member slides within the sliding cavity, and the mounting holes communicate with the sliding cavity. An abutment of the air bag is inserted into the sliding cavity from a corresponding mounting hole portion.

[0011] Optionally, the driving component includes a rack, a gear, and a first driver; the air bag is disposed along the rack, the rack is disposed on the inner wall of the mounting component opposite to the mounting hole, the first driver is disposed inside the sliding component, the first driver is connected to the gear, the gear meshes with the rack, and the first driver is used to drive the gear to rotate so as to drive the sliding component to reciprocate along the rack.

[0012] Optionally, the slider is provided with a screw hole and a guide hole; the driving component includes a lead screw, a guide rod and a second driver, the lead screw and the guide rod are arranged parallel to each other, the lead screw passes through and is screwed into the screw hole, the guide rod passes through the guide hole, the second driver is connected to the lead screw, the second driver is used to drive the lead screw to rotate, and the lead screw drives the slider to move.

[0013] Optionally, the end of the abutment near the bag body has a support end with an increased cross-sectional area.

[0014] Optionally, the number of air guiding components is two sets, with the two air guiding components spaced apart; the number of air bag components is two sets, with one air bag component corresponding to one air guiding component.

[0015] To solve the above-mentioned technical problems, another technical solution adopted by this utility model is to provide a massage device, including the above-mentioned pneumatic comfort system.

[0016] The beneficial effects of this utility model embodiment are as follows: Unlike the prior art, this utility model embodiment can drive the movement of the sliding member through the driving member of the air guiding component, and the inflation and deflation of the air bag can be controlled by a single sliding member. This greatly reduces the number of control valves, such as solenoid valves, required for the overall pneumatic comfort system, simplifies the structure of the pneumatic comfort system for controlling the air bag, reduces the manufacturing cost of the pneumatic comfort system, and the method of controlling inflation and deflation by using the mechanical structure of the air guiding component is more stable and reliable with a low failure rate, thus ensuring the stability of the pneumatic comfort system.

[0017] Furthermore, the addition of a control valve to the sliding component enables tapping or vibration massage to meet different user massage needs. A single high-frequency switching control valve can achieve the effect of the original valve body assembly composed of multiple valves, making the technical solution more ingenious and saving the cost of solenoid valves and circuit boards.

[0018] In addition, because the surface of the sliding part has an arc-shaped structure, it can push the massage air bag out when it reaches the bottom of the massage air bag, making it fit the user's massage area better. It also solves the problem of the limited height of the existing air bag. As a result, when the massage air bag deforms during inflation and deflation, the massage force is stronger and the comfort is greater! Attached Figure Description

[0034] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them.

[0035] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0036] Please see Figure 1 and Figure 2 The pneumatic comfort system 1000 includes an air source (not shown), an air guide assembly 1, and an air bag assembly 2. The air guide assembly 1 is connected to the air source, and the air guide assembly 1 can also control the connection or disconnection between the air source and the air bag assembly 2, thereby realizing the control of the inflation and deflation of the air bag assembly 2.

[0037] Understandably, a gas source is any device or container that can provide a gas supply, including but not limited to air pumps, gas cylinders, gas storage tanks, and gas storage bags. In this embodiment, preferably, the gas source is an air pump.

[0038] For the air guide assembly 1 mentioned above, please refer to... Figures 1 to 5The gas guiding component 1 includes a driving member 11 and a sliding member 12. The driving member 11 and the sliding member 12 are connected. The driving member 11 can generate continuous and stable power to drive the sliding member 12 to move along a preset direction. The sliding member 12 is provided with a first gas channel 121. One end of the first gas channel 121 is connected to a gas source, and the other end of the first gas channel 121 is provided with an inflation port 122. The first gas channel 121 is used to provide a path for the gas transmission in the gas source.

[0039] For the airbag assembly 2 mentioned above, please refer to... Figure 1 The air bag assembly 2 includes a plurality of air bags 21 disposed on the moving path of the slider 12. Each air bag 21 includes an abutment portion 211 and an inflatable and deformable bag body 212. The bag body 212 is disposed on the abutment portion 211. The abutment portion 211 is provided with a second gas channel 2111. One end of the second gas channel 2111 is connected to the bag body 212, and the other end of the second gas channel 2111 is provided with an abutment port 2112 that matches the inflation interface 122.

[0040] By controlling the contact state between the slider 12 and the contact portion 211 of the air bag 21, the state of the pneumatic comfort system 1000 can be divided into two categories, as follows:

[0041] When the sliding member 12 abuts against the contact portion 211 of any air bag 21, the inflation port 122 aligns with the contact port 2112, and the air source connects to the corresponding bag body 212 through the first gas channel 121 and the second gas channel 2111. At this time, the pneumatic comfort system 1000 is in the contact state. Specifically, the gas in the air source can sequentially pass through the first gas channel 121 of the sliding member 12, the contact port 2112 of the air bag 21, and the second gas channel 2111 provided in the contact portion 211 of the air bag 21 before entering the bag body 212 inside the air bag 21. When the sliding member 12 is misaligned with the contact portion 211 of the air bag 21, the inflation port 122 is misaligned with the contact port 2112, and the bag body 212 is disconnected from the air source. At this time, the pneumatic comfort system 1000 is in a disconnected state. Specifically, the connection between the first gas channel 121 and the second gas channel 2111 is disconnected, and the gas in the air source cannot enter the bag body 212 of the air bag 21 after passing through the first gas channel 121 of the sliding member 12, the contact port 2112 of the air bag 21, and the second gas channel 2111 set in the contact portion 211 of the air bag 21 in sequence.

[0042] Understandably, by driving the sliding member 12 to move through the driving member 11 of the aforementioned air guiding component 1, the contact state between the sliding member 12 and any one of the air bags 21 can be changed. This facilitates the inflation and deflation of the air bag 21 by the air source or the control valve installed in the sliding member 12. Compared with the pneumatic comfort system 1000 with a large number of control valves in the prior art, the structure of the pneumatic comfort system 1000 using the aforementioned air guiding component is simplified, reducing the manufacturing cost of the pneumatic comfort system 1000. Furthermore, due to the use of the mechanical structure of the air guiding component 1 combining the driving member 11 and the sliding member 12, the failure rate of the pneumatic comfort system 1000 is significantly reduced compared with the pneumatic comfort system 1000 with a large number of control valves, thus improving the durability of the pneumatic comfort system 1000.

[0043] In some embodiments, there are multiple air bags 21, which are spaced apart from each other. Specifically, the density of the air bags 21 can be controlled by adjusting the spacing between them to achieve different massage effects. For example, when the spacing between the air bags 21 is large, it can achieve area-specific massage, while when the spacing between the air bags 21 is small, it can achieve acupoint massage in specific areas. The driving member 11 is used to drive the sliding member 12 to move along a preset direction to adjust the air bags 21 that are connected to the sliding member 12. That is, the movement of the driving member 11 is used to select the air bags 21 that need to be inflated or deflated, and the massage effect is achieved by the change in the degree of gas filling in the air bags 21.

[0044] Understandably, the cooperation between the air guide assembly 1 and the air bag assembly 2 not only simplifies the structure of the pneumatic comfort system 1000, reduces the failure rate of the comfort system and improves its durability, but also utilizes the sliding member 12 to push up the contact part 211 of the air bag 21 when it comes into contact, so that the air bag 21 as a whole presents a slight bulge on the surface of the seat and other equipment, thereby making the air bag 21 fit the human body more closely and improving the user experience of the equipment using the pneumatic comfort system 1000.

[0045] It should be noted that the height of the air bag 21 is determined by the height difference between the inflation port 122 of the slider 12 and the contact port 2112 of the air bag 21 along the same direction and on the same plane. Users can choose according to the actual situation. This embodiment will not provide examples one by one.

[0046] In some embodiments, please refer to Figure 5The end face of the slider 12 near the air bag 21 is an arc-shaped surface 123, and the inflation port 122 is located at the top of the arc-shaped surface 123. The arc-shaped surface 123 reduces the resistance when the slider 12 contacts the contact part 211 of the air bag 21 during movement. The arc-shaped surface 123 also facilitates the manufacturing of the slider 12, optimizes the stress distribution on the surface of the slider 12 during manufacturing, and facilitates demolding. Furthermore, the arc-shaped surface 123 on the slider 12 can also reduce the noise when the slider 12 contacts the contact part 211.

[0047] Understandably, in order to further reduce the resistance when the slider 12 contacts the contact portion 211 of the air bag 21, in some embodiments, the end face of the contact portion 211 away from the bag body 212 is also set as an arc-shaped curved surface 2113 to reduce the resistance when the slider 12 contacts the contact portion 211 of the air bag 21 and reduce the noise of the pneumatic comfort system 1000.

[0048] In some embodiments, please refer to Figure 5 The top of the arc-shaped surface 123 is provided with a groove 1231, and the inflation port 122 is provided at the bottom of the groove 1231. When the sliding member 12 abuts against the abutting part 211, the abutting part 211 is partially received in the groove 1231, and the abutting port 2112 is connected with the inflation port 122, thereby improving the accuracy of the connection between the abutting port 2112 and the inflation port 122, avoiding the alignment deviation caused by the inaccurate alignment between the abutting port 2112 and the inflation port 122, which in turn affects the gas filling degree of the bag body 212 of the air bag 21.

[0049] In some embodiments, a sealing gasket (not shown) is provided at the bottom of the groove 1231. When the abutment portion 211 is partially received in the groove 1231, the abutment portion 211 and the groove 1231 together hold the sealing gasket, thereby improving the sealing performance when the slider 12 abuts the abutment portion 211.

[0050] In some embodiments, the gas guiding assembly 1 further includes a control valve (not shown). The control valve is disposed within the second gas channel 2111 and is used to control the opening and closing of the second gas channel 2111, thereby controlling the opening and closing between the gas source and the inflation port of the sliding member 12. Specifically, the control valve can be a two-position three-way solenoid valve and a corresponding PCB assembly that can be electrically controlled to control the solenoid valve. The internal valve core switches between a first position and a second position under the action of an electromagnetic spring, and is provided with an inflation channel and a deflation channel, that is, it has three gas ports: an inlet, a deflation port, and an inflation port. Generally, when the valve core is in the first position, the inflation port is connected to the inlet through the inflation channel, and the deflation channel is closed. When the valve core is in the second position, the inflation port is connected to the inlet through the deflation channel, and the inflation channel is closed. The two-position three-way solenoid valve is a conventional valve body in the art and will not be further described here. In this embodiment, the inflation channel of the control valve is connected to the first gas channel 121 to facilitate the passage of the first gas. The gas in channel 121 can be transferred through the inflation channel, and the deflation channel is connected to the external environment so that the gas can be discharged to the external environment after passing through the deflation channel. The control valve can control the opening or closing of the inflation channel or the deflation channel, and thus control the pneumatic comfort system 1000 to be in inflation mode or deflation mode, thereby realizing the cyclic inflation and deflation operation of the air bag 21. Furthermore, the duration of the control valve in inflation mode or deflation mode can be adjusted to change the gas filling degree in bag 212, forming a variety of massage modes. For example, different massage intensities can be achieved according to the gas filling degree in bag 212, and tapping massage or ordinary massage can be achieved according to the inflation and deflation frequency of the gas in bag 212.

[0051] It is understood that the control valves mentioned above include, but are not limited to, two-position three-way valves and other solenoid valves.

[0052] In some embodiments, please refer to Figure 1 The air guiding assembly 1 also includes a mounting member 13, which has a sliding cavity 131 and multiple mounting holes 132. The sliding cavity 131 is used to preset the movement trajectory of the sliding member 12, so that the movement direction of the sliding member 12 is limited to the extension direction of the sliding cavity 131, and the movement path of the sliding member 12 is limited to the sliding cavity 131. The sliding member 12 slides within the sliding cavity 131. The mounting holes 132 communicate with the sliding cavity 131. The abutment of an air bag 21 is inserted into the sliding cavity 131 from a corresponding mounting hole 132 portion to facilitate the positioning of the air bag 21 and ensure the positioning and abutment of the air bag 21 and the sliding member 12. Furthermore, the multiple mounting holes 132 are spaced apart, and the spacing direction of the multiple mounting holes 132 is consistent with the extension direction of the sliding cavity 131 to ensure the cooperation between the sliding member 12 and the air bag 21.

[0053] It should be noted that there are various ways to achieve the movement of the sliding member 12 driven by the driving member 11, including but not limited to the meshing structure of the rack 111 and the gear 112, the meshing structure of the lead screw 114 and the guide rod 115, etc., as long as the driving member 11 can drive the sliding member 12 to move in the preset direction.

[0054] In some embodiments, please refer to Figure 1 The driving component 11 adopts a meshing structure of rack 111 and gear 112. Specifically, the driving component 11 includes rack 111, gear 112 and first driver 113. The air bag 21 is arranged along rack 111. Rack 111 is arranged on the inner wall of mounting component 13 opposite to mounting hole 132. First driver 113 is arranged inside sliding component 12. First driver 113 is connected to gear 112. Gear 112 meshes with rack 111. First driver 113 is used to drive gear 112 to rotate so as to drive sliding component 12 to reciprocate along rack 111.

[0055] Furthermore, the sliding member 12 is provided with a mounting cavity, in which the first driver 113 and the gear 112 are housed. The gear 112 is rotatably disposed in the mounting cavity, and a portion of the gear 112 extends out of the mounting cavity and meshes with the rack 111. Thus, the first driver 113 drives the gear 112 to rotate, and the gear 112 reciprocates along the extension direction of the rack 111, thereby driving the sliding member 12 to reciprocate along the extension direction of the rack 111, thereby matching different air bags 21.

[0056] Understandably, a reducer (not shown) is provided between the first driver 113 and the gear 112. One end of the reducer is fixed to the output shaft of the first driver 113, and the other end meshes with the gear 112, so that the rotational speed of the first driver 113 is reduced by the reducer to match the required rotational speed of the gear 112, thereby achieving precise alignment between the sliding member 12 and the air bag 21. Furthermore, the structure of the gear 112 and rack 111 can withstand a large load. Therefore, the pneumatic comfort system 1000 with this structure is suitable for areas with high load, such as the area corresponding to the buttocks of the human body.

[0057] In other embodiments, please refer to Figure 6 and Figure 7The driving component 11 adopts a cooperative structure of lead screw 114 and guide rod 115. Correspondingly, the sliding component 12 is provided with screw hole 125 and guide hole 124. Specifically, the driving component 11 includes lead screw 114, guide rod 115 and second driver 116. Lead screw 114 and guide rod 115 are arranged parallel to each other. Lead screw 114 passes through and is screwed into screw hole 125. Guide rod 115 passes through guide hole 124. Second driver 116 is connected to lead screw 114. Second driver 116 is used to drive lead screw 114 to rotate. Lead screw 114 drives sliding component 12 to move. Guide rod 115 is used to cooperate with screw to guide sliding component 12, guide the reciprocating motion direction of sliding component 12, and guide rod 115 and lead screw 114 work together to limit sliding component 12, avoiding the situation where sliding component 12 rotates in the same circumferential direction as lead screw 114 during the process of moving driven by lead screw 114.

[0058] Understandably, the drive unit 11 adopts a structure in which the lead screw 114 and the guide rod 115 cooperate, which has high control precision, smooth operation, low noise, and simple structure that is easy to install and maintain. Therefore, the pneumatic comfort system 1000 with this structure is suitable for areas with high massage precision and high noise control requirements, such as the back and waist areas of the human body.

[0059] In some embodiments, the abutment portion 211 has a support end 211a with an increased cross-sectional area at one end near the bag body 212. Specifically, the abutment portion 211 includes a support end 211a and a connecting portion 211b, one end of the connecting portion 211b is fixed to the support end 211a, the other end of the connecting portion 211b is fixed to the bag body 212, a portion of the second gas channel 2111 is disposed at the support end 211a, and the other portion of the second gas channel 2111 is disposed at the connecting portion 211b. Along the direction perpendicular to the supporting end 211a toward the connecting part 211b, the cross-sectional area of ​​the supporting end 211a is larger than the diameter of the mounting hole 132, so that when the supporting end 211a passes through the mounting hole 132 and is received in the mounting cavity, after being abutted and lifted by the sliding member 12, the end of the supporting end 211a near the mounting hole 132 abuts against the inner wall of the mounting cavity; the connecting part 211b is used to connect the supporting end 211a and the air bag 21, and the connecting end can reciprocate along the axial direction of the mounting hole 132, and the connecting part 211b and the supporting end 211a are used to limit the movement stroke of the air bag 21 along the axial direction of the mounting hole 132.

[0060] Specifically, when the air bag 21 is not abutted and lifted by the sliding member 12, the bag body 212 fixed at the other end of the connecting part 211b abuts against the outer wall of the mounting member 13; when the air bag 21 is abutted and lifted by the sliding member 12, the supporting end 211a fixed at one end of the connecting part 211b abuts against the inner wall of the mounting cavity on the side where the mounting hole 132 is provided. The distance difference between the two is the travel distance of the air bag 21 along the axial direction of the mounting hole 132. This travel distance is determined by the length of the connecting part 211b and can be set according to actual needs. This embodiment will not provide further examples.

[0061] In some embodiments, there are two sets of air guiding components 1, with the two air guiding components 1 spaced apart, so that the two air guiding components 1 together constitute a large-area coverage air guiding component 1 control area; correspondingly, there are two sets of air bag components 2, with one air bag component 2 corresponding to one air guiding component 1, thereby forming a large-area massage coverage area, which can reduce the volume of air bag 21 and realize the fine area massage of the air bag 21 comfort system, such as local acupoint massage, etc.

[0062] In some embodiments, the pneumatic comfort system 1000 further includes a control component (not shown), which is electrically connected to an external power source and also electrically connected to the air guide assembly 1 and the air source, respectively. The control component facilitates electrical communication between the air guide assembly 1 and the air source and the outside world. It also controls the operating state of the air guide assembly 1, such as controlling the operating time of the drive element 11 and the forward / reverse rotation of the drive element 11. Furthermore, the control component controls the start / stop of the air source, the operating duration of the air source, and the gas supply flow rate. The control component also includes a processor that executes one or more computer programs stored in a memory. When executing these programs, the processor enables the pneumatic comfort system 1000 to implement diverse massage modes.

[0063] In this embodiment, the pneumatic comfort system 1000 includes an air source, an air guide assembly 1, an air bag assembly 2, and a control assembly. The air source and the air guide assembly 1 are both electrically connected to the control assembly. The air source is connected to the air guide assembly 1, and the air guide assembly 1 is used to control the connection and disconnection between the air source and any one of the air bags 21 in the air bag assembly 2, so that different air bags 21 of the pneumatic comfort system 1000 can perform different degrees of inflation and deflation operations, thereby forming a variety of massage modes. The air guiding component 1 includes a driving member 11 and a sliding member 12, which are connected. The driving member 11 drives the sliding member 12 to move along a preset direction. The sliding member 12 is provided with a first gas channel 121, one end of which is connected to a gas source, and the other end of which is provided with an inflation port 122. The air bag component 2 includes a plurality of air bags 21 disposed on the moving path of the sliding member 12. Each air bag 21 includes an abutment portion 211 and an inflatable and deformable bag body 212. The bag body 212 is disposed on the abutment portion 211, and the abutment portion 211 is provided with a second gas. The second gas channel 2111 has one end connected to the bag body 212 and the other end provided with an abutment port 2112 that matches the inflation interface 122. When the sliding member 12 abuts against the abutment part 211 of any air bag 21, the inflation interface 122 connects with the abutment port 2112, and the gas source is connected to the corresponding bag body 212 through the first gas channel 121 and the second gas channel 2111. When the sliding member 12 is misaligned with the abutment part 211 of the air bag 21, the inflation interface 122 is misaligned with the abutment port 2112, and the bag body 212 is disconnected from the gas source. Through the above structure, the drive member 11 of the air guide assembly 1 controls the contact or misalignment relationship between the sliding member 12 and the contact portion 211 of the air bag 21 to achieve the connection or disconnection between the air source and any air bag 21 in the air bag assembly 2. This achieves a control effect similar to that of the solenoid valve in the existing pneumatic comfort system 1000, simplifies the structure of the pneumatic comfort system 1000 to realize the control function, reduces manufacturing costs, and, due to the mechanical control method of the drive member 11 and the sliding member 12 of the air guide assembly 1, its failure rate is lower than that of the solenoid valve, resulting in lower maintenance costs for the pneumatic comfort system 1000 in the later stage.

[0064] This utility model also provides embodiments of massage devices; please refer to [link / reference]. Figure 8 The massage device 2000 includes the pneumatic comfort system 1000 and the seat described above. The pneumatic comfort system 1000 is installed inside the seat. For the specific structure and function of the pneumatic comfort system 1000, please refer to the above embodiments, which will not be described in detail hereafter.

[0065] It is understood that the massage equipment mentioned above includes, but is not limited to, seats, cushions, massage beds or sofas, etc. In this embodiment, the massage equipment is preferably a seat.

[0066] This utility model also provides a massage method applied to the aforementioned pneumatic comfort system 1000, wherein the control valve is preferably a two-position three-way valve. Please refer to [link / reference needed]. Figure 9 The massage method involves driving the sliding member 12 to move by the driving member 11 until the sliding member 12 abuts against the contact part 211 of the preset air bag 21, and controlling the preset air bag 21 to perform at least a number of inflation steps S1 and deflation steps S2 alternately by the control valve.

[0067] The inflation step S1 includes: opening the inflation channel and closing the deflation channel in the control valve to guide air from the air source into the air bag 21 and maintaining the inflation time T so that the air pressure in the air bag 21 increases from the first air pressure value to the second air pressure value.

[0068] It is understandable that the inflation time maintained during the process of the air pressure in the air bag 21 increasing from the first air pressure value to the second air pressure value should be determined by factors such as the actual volume of the air bag 21, the difference between the first air pressure value and the second air pressure value, and the gas flow rate of the air source. Therefore, this embodiment will not provide specific examples.

[0069] Specifically, in the inflation step S1, the inflation channel of the control valve is opened and the deflation channel is closed. The gas in the gas source flows through the first gas channel 121, the inflation channel, and the second gas channel 2111 and is then guided into the air bag 21, so that the air pressure value in the bag body 212 of the air bag 21 gradually increases from the first air pressure value to the second air pressure value, thereby realizing the inflation and expansion process of the bag body 212 of the air bag 21.

[0070] Understandably, the limitation of the second air pressure value is to calibrate the gas filling degree inside the bag body 212 of the air bag 21. The maximum second air pressure value that the bag body 212 of different volumes and materials can withstand is different. In this embodiment, no examples are given for the material and volume of the air bag 21, as long as it is suitable for actual use.

[0071] The deflation step S2 includes: closing the inflation channel and opening the deflation channel in the control valve to guide the gas in the air bag 21 out through the deflation channel in the control valve, and maintaining the deflation time Q so that the air pressure in the air bag 21 decreases from the second air pressure value to the first air pressure value.

[0072] It is understandable that the duration of deflation that the air pressure in the air bag 21 takes to decrease from the second air pressure value to the first air pressure value should be determined by factors such as the actual volume of the air bag 21, the difference between the first air pressure value and the second air pressure value, and the flow rate of the deflation channel of the control valve. Therefore, this embodiment will not provide specific examples.

[0073] It should be noted that the gas flow rate from the bag body 212 of the air bag 21 to the outside through the control valve is not constant within a unit of time. This is because the gas pressure inside the bag body 212 of the air bag 21 gradually decreases, and the gas flow rate from the bag body 212 to the outside through the control valve generally decreases gradually.

[0074] Specifically, in the venting step S2, the venting channel of the control valve is opened and connected to the external environment so that the gas can be discharged to the external environment through the venting channel. The inflation channel is closed, and the path of the gas in the gas source to the bag body 212 of the gas bag 21 is cut off. The gas in the bag body 212 of the gas bag 21 can flow through the second gas channel 2111 and be discharged to the external environment through the venting channel, so that the gas pressure value in the bag body 212 of the gas bag 21 gradually decreases from the second gas pressure value to the first gas pressure value, thereby realizing the venting process of the bag body 212 of the gas bag 21.

[0075] The second atmospheric pressure value is greater than the first atmospheric pressure value, and the first atmospheric pressure value is greater than or equal to 0 kPa. For example, the first atmospheric pressure values ​​are: 0 kPa, 10 kPa, 15 kPa, 20 kPa, 25 kPa, 30 kPa, etc.

[0076] When the first air pressure is 0 kPa, in the inflation step S1 under this state, the bag 212 of the air bag 21 undergoes a process from being unfilled to being completely filled with air; in the deflation step S2 under this state, the bag 212 of the air bag 21 undergoes a process from being completely filled with air to being completely expelled. At this time, the massage mode achieved by the air bag 21 in the pneumatic comfort system 1000 is a conventional frequency massage, that is, the air bag 212 is completely filled with air, and then the air bag 212 is completely expelled, and this cycle is repeated to constitute the complete inflation and deflation of the air bag 21.

[0077] The working logic of ordinary massage is further enriched and explained accordingly: the air bag 21 is fully inflated and deflated at a low frequency, that is, the control valve is controlled to maintain the inflation time T, so that the air pressure value in the air bag 21 increases from 0 kPa to the second air pressure value, and then the control valve is controlled to maintain the deflation time Q, so that the air pressure value in the air bag 21 decreases from the second air pressure value to 0 kPa, thereby completing one massage. The same air bag 21 can repeat the above working logic multiple times. Users can also customize the number of cycles, including but not limited to: once, twice, or three times. Furthermore, users can customize the massage number for different air bags 21. For example, if the user specifies that the air bag 21A in the air bag assembly 2 will have two massage cycles and the air bag 21B in the air bag assembly 2 will have three massage cycles, then the drive unit 11 will drive the slider 12 to move to the corresponding position of the air bag 21A, so that the air bag 21A is abutted and held by the slider 12, and two complete inflation and deflation cycles will be performed. Then the drive unit 11 will drive the slider 12 to move to the corresponding position of the air bag 21B, so that the air bag 21B is abutted and held by the slider 12, and three complete inflation and deflation cycles will be performed. This massage mode, which relies on the working logic of the drive unit 11, the slider 12, and the control valve, is simple, reliable, and easy to understand. It only requires controlling the number of massage cycles and selecting the air bag 21 that needs to be inflated and deflated to achieve a variety of ordinary massage modes.

[0078] It should be noted that airbags 21A and 21B are used only to distinguish between different types of airbags 21.

[0079] In some embodiments, preferably, the first air pressure value is greater than or equal to 20 kPa, so that the air pressure inside the air bag 21 is maintained at the minimum air pressure value of 20 kPa.

[0080] When the first air pressure is 20 kPa, in the inflation step S1 under this state, the gas inside the bag 212 of the air bag 21 undergoes a process from partially filling with gas (i.e., the air bag 21 is maintained at around 20 kPa) to being completely filled with gas. In the deflation step S2 under this state, the gas inside the bag 212 of the air bag 21 undergoes a process from being completely filled with gas to partially being expelled. At this time, the massage method implemented by the air bag 21 in the pneumatic comfort system 1000 is a percussion massage, that is, the gas inside the bag 212 of the air bag 21 is completely filled with gas, and then the gas inside the bag 212 of the air bag 21 is partially expelled to maintain the first air pressure at 20 kPa. This cycle is repeated, forming the working logic of the air bag 21 being filled, partially deflated, and then partially inflated again, resulting in a relatively stronger overall massage intensity. The working logic of the percussion massage is further enriched and explained accordingly: First, a pre-inflation step is performed to raise the air pressure inside the airbag to the second air pressure value, i.e., a full state. Then, the airbag 21 is partially inflated and deflated at high frequency. The control valve is controlled to maintain the deflation time Q', causing the air pressure inside the airbag 21 to decrease from the second air pressure value to 20 kPa. Then, the control valve is controlled to maintain the inflation time T', causing the air pressure inside the airbag 21 to increase from 20 kPa back to the second air pressure value. This completes one cycle of inflation and deflation during a percussion massage. This ensures that the air pressure inside the airbag 21 continuously cycles between 20 kPa and the second air pressure value. To further enrich the massage modes, users can customize the number of repetitions, including but not limited to: once, ten times, or twenty times. Furthermore, users can customize the massage frequency for different air bags 21. For example, if a user specifies that air bag 21A in air bag assembly 2 will cycle ten times and air bag 21B in air bag assembly 2 will cycle twenty times, then the drive member 11 will drive the slider 12 to move to the corresponding position of air bag 21A, so that air bag 21A is abutted and held by the slider 12, and undergoes ten partial inflation / deflation cycles. Then, the drive member 11 will drive the slider 12 to move to the corresponding position of air bag 21B, so that air bag 21B is abutted and held by the slider 12, and undergoes twenty partial inflation / deflation cycles, thereby achieving a tapping-like massage effect from multiple air bags 21.

[0081] It should be noted that the deflation time Q' and inflation time T' in percussion massage are different from the deflation time Q and inflation time T in ordinary massage. When the first air pressure value is 20 kPa, the inflation time T' required to increase from the first air pressure value to the second air pressure value is significantly less than the inflation time T required to increase from the first air pressure value to the second air pressure value when the first air pressure value is 0 kPa; when the first air pressure value is 20 kPa, the deflation time Q' required to decrease from the second air pressure value to the first air pressure value is significantly less than the deflation time Q required to decrease from the second air pressure value to the first air pressure value when the first air pressure value is 0 kPa.

[0082] Before the actual alternating execution of inflation step S1 and deflation step S2, the air bag 21 is usually in the deflation completed state, that is, the air bag 21 is at the first air pressure value. It is necessary to pre-inflate the air bag 21 with gas so that the air bag 21 can smoothly achieve the above-mentioned tapping massage mode.

[0083] Therefore, in some embodiments, the massage method further includes a pre-charging step S3, which includes:

[0084] By controlling the opening of the inflation channel and the closing of the deflation channel of the control valve, air from the air source is guided into the air bag 21 and the pre-inflation time is maintained, so that the air pressure in the air bag 21 rises from 0 to a second air pressure value or above.

[0085] After completing the pre-charge step S3, the deflation step S2 and the inflation step S1 are executed alternately, so that the pneumatic comfort system 1000 can perform the above-mentioned ordinary massage or percussion massage.

[0086] Understandably, the pre-charge time of this pre-charge step S3 is greater than or equal to the inflation time T, so as to ensure that the air pressure value in the air bag 21 is greater than or equal to the second air pressure value after the pre-charge step S3 is completed.

[0087] This utility model embodiment also provides an embodiment of a cyclic massage method. Please refer to [link / reference]. Figure 10 The cyclic massage method is applied to the pneumatic comfort system 1000 described above. For the specific structure and function of the pneumatic comfort system 1000, please refer to the above embodiments; details will not be repeated here. The cyclic massage method includes:

[0088] Step S1': Obtain the set cycle stroke, set the movement frequency, and the starting air bag 21;

[0089] Understandably, the cycle stroke refers to the movement path formed by the combination of the number of air bags 21 that the drive member 11 drives the slider 12 along its movement path; the movement frequency refers to the number of times the slider 12 moves along the cycle stroke controlled by the method; the starting air bag 21 refers to one of the air bags 21 in any air bag assembly 2 as the first air bag 21 to perform the inflation step S1 and deflation step in the cycle stroke of the cycle massage method; thus, various massage modes can be achieved by arranging and combining multiple parameters such as the cycle stroke, movement frequency, and the position of the starting air bag 21. For example, the cycle stroke is set to the movement path formed by the combination of three air bags 21 along the movement path of the slider 12, the movement frequency is set to the number of times the slider 12 moves along the cycle stroke is three, and the starting air bag 21 is designated as the first air bag 21 in the air bag assembly 2 along the movement path of the slider 12.

[0090] Step S2': Control the slider 12 to move back and forth in a preset path from the starting air bag 21, according to the preset cycle stroke and the preset moving frequency, so that the slider 12 cyclically docks with each air bag 21 in turn.

[0091] The preset path, cycle length, and movement frequency are all obtained by the user in step S1'. Of course, a fixed mode can also be preset for the user to choose from, enriching the massage modes. Examples will not be given one by one.

[0092] Step S3': When the sliding member 12 is connected to the air bag 21, the control valve is opened; when the sliding member 12 is misaligned with the air bag 21, the control valve is closed.

[0093] Specifically, after the control valve is opened, the pneumatic comfort system enters the inflation mode or deflation mode, thereby realizing the massage method described above. For details, please refer to the above embodiments, which will not be described in detail here.

[0094] Furthermore, when performing the above-mentioned cyclical massage method, it is also necessary to combine it with the above-mentioned massage methods, that is, to combine the two modes of ordinary massage and tapping massage, to further enrich the massage modes and enhance the user experience.

[0095] In some embodiments, step S1' of obtaining the preset cycle time further includes:

[0096] Receive the air bag 21 that the user has specified as the need to perform cyclic massage;

[0097] Based on the determined airbag 21 and the preset airbag 21 distance model, the set cycle stroke is determined.

[0098] Understandably, the airbags 21 that need to be determined in the above steps refer to determining the number of airbags 21, so as to initially determine the range of the preset movement distance. The airbag 21 distance model mentioned above refers to the spacing between several airbags 21 in the airbag assembly 2. This spacing, together with the determined airbags 21, accurately determines the preset movement distance, thereby improving the user experience of the pneumatic comfort system 1000 with a cyclic massage method.

[0099] To enhance the user-customizability of the cyclic massage method, in some embodiments, the step of obtaining the initial air bag 21 further includes:

[0100] One of the airbags 21 that the user has specified as the area requiring cyclic massage is used as the starting airbag 21. This allows for targeted massage of the areas or parts of the body that the user needs.

[0101] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this utility model; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
