Description

Technical Field

[0001] This invention relates to the field of assistive medical device technology, and more specifically, to a design method for airway diversion in a gas diversion device. Background Technology

[0002] Gas diversion devices can be used in air wave or air pressure massage products. These products require inflation and deflation to achieve the massage function. These products generally have at least two separate massage bodies. Therefore, in order to achieve synchronous massage of different massage bodies at the same time, the same inflation device needs to be used to control the inflation or deflation of multiple massage bodies simultaneously through a solenoid valve. Therefore, in order to ensure the uniformity of airflow distribution between different massage bodies and to ensure the massage intensity, a gas diversion device needs to be set between the inflation device and the massage body.

[0003] However, existing gas diversion devices mostly use a single-layer airway for diversion, resulting in a complex pipeline layout, which leads to a large size of the gas diversion device. Furthermore, the connection between the gas diversion device and the solenoid valve and multiple massage units is relatively complex and inconvenient to assemble. Therefore, it is necessary to propose a design method for airway diversion in gas diversion devices to at least partially solve the problems existing in the prior art. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] The design method involves setting the number of connectors based on the number of interfaces on a single plug socket, and determining the number of shunt layers based on the total number of interfaces on all plug sockets.

[0008] Preferably, the plug socket is connected to the air supply end of the device, and the multiple interfaces on one plug socket correspond to multiple air passages of the device; the connector is connected to the inflation device through a solenoid valve.

[0009] If the number of interfaces on a plug socket is set to be the same as the number of connectors, then the connectors and interfaces on each plug socket are numbered one-to-one, so that interfaces with the same number on different plug sockets are connected to the same connector with the corresponding number. The solenoid valve can control the connection and disconnection of a connector and the inflation device individually.

[0010] Preferably, the number of shunt layers is determined based on the total number of interfaces on all plug sockets, including:

[0012] Preferably, the number of interfaces with the same number on different plug sockets is at least two.

[0013] Preferably, the secondary diversion airway is formed by sealing and inserting a first airway groove and a second airway groove respectively disposed on the first plate and the second plate.

[0014] The first airway groove is provided with at least two first through holes that communicate with interfaces with the same number on different plug sockets, and the second airway groove is provided with a second through hole that communicates with a connector with the corresponding number.

[0015] The second plate has a connector communicating with the second through hole on the side away from the first plate.

[0016] The first plate is a plug-in air distribution plate or a middle layer air distribution plate, and the second plate is a middle layer air distribution plate or a bottom layer air distribution plate.

[0017] Preferably, a connecting pipe is inserted into the first through hole on the distribution layer located away from the plug gas distributor, and the connecting pipe is correspondingly located on the back side of the interface on the plug gas distributor, so that the interface is connected to the first through hole.

[0018] Preferably, the first airway groove is provided with a sealing gasket, and the second airway groove can be inserted into the first airway groove and abut against the sealing gasket to form a two-stage diversion airway.

[0019] Preferably, the secondary diversion airway includes: a main airway and at least two branch airways A that are interconnected, a second through hole located at the end of the main airway, and a first through hole located at the end of the branch airway A away from the main airway; the length of the line from each first through hole to the second through hole is the same.

[0020] Preferably, it further includes: a primary air diversion channel for connecting the inflation device and the connector, wherein one side of the primary air diversion channel is provided with an air inlet channel connected to the inflation device, and the other side is provided with an air outlet channel connected to the connector, the number of air outlet channels being the same as the number of connectors; and the solenoid valve is provided on the air outlet channel.

[0021] Preferably, the primary diversion airway includes: a third airway, a fourth airway, a fifth airway, and a sixth airway arranged sequentially from the inside out;

[0022] One end of the third air passage is connected to the air intake passage, and the other end is connected to the fourth air passage;

[0023] The fourth airway is formed by multiple branch airways B distributed circumferentially, and each branch airway B is connected to the end of the third airway away from the air intake.

[0024] The fifth airway is formed by a plurality of branch airways C spaced apart along the axial direction. The branch airways C are annular airways, and the number of branch airways C is the same as the number of outlet airways. The number of branch airways C is the same as the number of branch airways B, or the number of branch airways B is a multiple of the number of branch airways C. The branch airways C are connected to the corresponding number of branch airways B.

[0025] The sixth airway is formed by multiple branch airways D distributed at intervals along the axial direction. The branch airways D are annular airways. The number of branch airways D is the same as the number of outlet airways, and they are interconnected. The multiple branch airways D are respectively connected to multiple branch airways C, and the connection points are set far away from the outlet airways.

[0026] Compared with the prior art, the present invention has at least the following beneficial effects:

[0027] The gas diversion device of the present invention has a gas channel diversion design method that can arrange the gas channels of the gas diversion device on different diversion layers by setting multiple diversion layers, which simplifies the gas channel layout. Furthermore, it can be directly plugged into the device being used through the plug socket and can be easily connected to the solenoid valve through the connector, thus achieving convenient connection.

[0028] The number of flow dividers is determined based on the number of interfaces on the plug socket. On the basis of ensuring that each flow divider can be fully utilized, a reasonable gas channel layout is carried out to reduce the volume of the gas flow divider.

[0029] Through a multi-level flow distribution layout design, this technology overcomes the problems of complex or unachievable single-layer gas channel layouts, difficulty in meeting the size requirements of device plugs, large gas distribution device size, and complex assembly found in existing technologies. The plug sockets and connectors simplify the connection between the device plug, solenoid valve, and the device, improving ease of connection. Furthermore, the multi-level flow distribution layout design allows for an increase in the number of flow distribution layers as the number of device plugs increases, reducing the complexity of the gas channel layout and effectively controlling the device's large size. Moreover, the device is compact, can be used as a standard component, and is easy to assemble, effectively improving assembly efficiency and saving assembly costs.

[0030] The gas diversion device of the present invention is designed to divert gas flow through a gas channel. Other advantages, objectives and features of the present invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of the present invention.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0046] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0047] like Figure 2 As shown, the present invention provides a design method for gas channel diversion in a gas diversion device, comprising:

[0048] The gas splitting device includes: a plug gas splitting seat 1 connected in sequence and capable of forming multiple splitting layers 7, at least one middle layer splitting plate 2 and a bottom layer splitting plate 3; at least two plug seats 4 disposed on the plug gas splitting seat 1 and communicating with the splitting layers 7; and a connector 5 disposed on the middle layer splitting plate 2 and the bottom layer splitting plate 3 and extending to the outside of the bottom layer splitting plate 3.

[0049] The design method is to set the number of connectors 5 according to the number of interfaces 6 on a plug socket 4, and to determine the number of shunt layers 7 according to the total number of interfaces 6 on all plug sockets 4.

[0050] The plug-in gas distribution socket 1 is used to connect with the device in use. The connector 5 can be connected to the inflation device 15 through a solenoid valve. When inflation, the gas entering through the connector 5 can be discharged simultaneously from multiple plug sockets 4 under the diversion effect of the diversion layer 7, so as to realize the simultaneous inflation of multiple devices in use. When deflation, a negative pressure is formed at the connector 5, so the gas in multiple devices in use is simultaneously drawn in and can be uniformly converged to the connector 5 through different plug sockets 4 via the diversion layer 7, so as to realize the simultaneous deflation.

[0051] By setting multiple flow dividers 7, the gas channels of the gas flow divider can be arranged on different flow dividers 7, which simplifies the gas channel layout. Furthermore, it can be directly plugged into the equipment being used through the plug socket 4, and can be easily connected to the solenoid valve through the connector 5, thus achieving convenient connection.

[0052] The number of flow dividers 7 is determined based on the number of interfaces 6 on the plug socket 4. On the basis of ensuring that each flow divider 7 can be fully utilized, a reasonable gas channel layout is carried out to reduce the volume of the gas flow divider.

[0053] like Figures 1-3 As shown, the plug socket 4 is further connected to the air supply end of the device, and the multiple interfaces 6 on the plug socket 4 correspond to multiple air passages of the device; the connector 5 is connected to the inflation device 15 through a solenoid valve.

[0054] If the number of interfaces 6 on a plug socket 4 is set to be the same as the number of connectors 5, then the connectors 5 and the interfaces 6 on each plug socket 4 are numbered one-to-one, so that the interfaces 6 with the same number on different plug sockets 4 are connected to the same connector 5 with the corresponding number. The solenoid valve can control the connection and disconnection between a connector 5 and the inflation device 15 individually.

[0055] Taking the leg massager as an example, two massagers need to massage both legs simultaneously. To achieve this massage function, multiple air paths are required, and the inflation and deflation of different air paths are staggered. The multiple air paths of one device are connected to multiple interfaces 6 of a plug 4. In order to achieve synchronous massage of the two massagers, the number of the interface 6 on each plug 4 corresponds one-to-one with multiple connectors 5. Assuming that there are four interfaces 6 on a plug 4, the number of connectors 5 is also four. That is, the massager has four air paths. Through the connection of the diversion layer 7, the interfaces 6 with the same number on different plug 4 can be connected to the corresponding numbered connectors 5. Thus, through the control of the solenoid valve, the synchronous massage of the two massagers can be achieved.

[0056] For example, if the four interfaces 6 on the two plug sockets 4 are numbered 1, 2, 3, and 4, then the corresponding connectors 5 are also numbered 1, 2, 3, and 4. In this case, the two interfaces 6 numbered 1 are connected to the connectors 5 numbered 1 through the shunt layer 7.

[0057] like Figure 4 and Figure 7 As shown, the number of shunt layers 7 is further determined based on the total number of interfaces 6 on all plug sockets 4, including:

[0058] Each shunt layer 7 includes at least two secondary shunt channels 8, and the same numbered interfaces 6 on different plug sockets 4 are connected to the same connector 5 with the corresponding number through the same secondary shunt channel 8.

[0059] A secondary split airway 8 is used to provide an interface 6 with the same number and a connector 5 with the corresponding number. For example, two interfaces 6 with the number 2 are connected to the connector 5 through a secondary split airway 8. Therefore, the number of split layers 7 can be determined based on the number of interfaces 6 and the number of secondary split airways 8 that each split layer 7 can accommodate.

[0060] like Figures 5-8 As shown, in one embodiment, the secondary diversion airway 8 is formed by sealing and inserting a first airway groove 810 and a second airway groove 820 respectively disposed on the first plate and the second plate.

[0061] The first air passage groove 810 is provided with at least two first through holes 811 that communicate with the same numbered interfaces 6 on different plug sockets 4, and the second air passage groove 820 is provided with a second through hole 821 that communicates with the corresponding numbered connector 5.

[0062] The second plate has a connector 5 on the side away from the first plate that communicates with the second through hole 821;

[0063] The first plate is either a plug-in air distribution plate 1 or a middle layer air distribution plate 2, and the second plate is either a middle layer air distribution plate 2 or a bottom layer air distribution plate 3.

[0064] The secondary diversion channel 8 is formed by sealing and inserting the first channel groove 810 and the second channel groove 820 set on two plates. The two plates can be snapped together and fixed, which facilitates the overall installation of the gas diversion device and makes assembly simpler.

[0065] During inflation, gas can enter the secondary diversion channel 8 through the second through hole 821 for diversion, and then simultaneously enter multiple interfaces 6 with the same number after passing through each first through hole 811, so as to supply gas to the same gas path for different devices.

[0066] like Figure 5As shown, further, a connecting pipe 9 is inserted into the first through hole 811 on the diversion layer 7 located away from the plug gas distribution seat 1. The connecting pipe 9 is correspondingly located on the back side of the interface 6 on the plug gas distribution seat 1, so that the interface 6 is connected to the first through hole 811.

[0067] Since there are at least two flow distribution layers 7, the secondary flow distribution channels 8 on the flow distribution layer 7 located away from the plug air distribution seat 1 need to be connected to the interface 6 through the connecting pipe 9. This allows the interface 6 to be directly connected to the secondary flow distribution channel 8, making the air channel layout more reasonable and simple.

[0068] like Figure 3 As shown, the first airway groove 810 is further provided with a sealing gasket 10, and the second airway groove 820 can be inserted into the first airway groove 810 and abut against the sealing gasket 10 to form a two-stage diversion airway 8.

[0069] To ensure sealing, a sealing gasket 10 of the same shape is provided in the first air passage groove 810. After the two plates are fastened together, the second air passage groove 820 can be inserted into the first air passage groove 810. The second air passage groove 820 presses against the sealing gasket 10 to achieve a seal, thereby forming a secondary diversion air passage 8 with better sealing performance.

[0070] like Figure 7 As shown, in one embodiment, the secondary diversion airway 8 includes: a main airway 830 and at least two branch airways A840 that are interconnected; a second through hole 821 is located at the end of the main airway 830; and a first through hole 811 is located at the end of the branch airway A840 away from the main airway 830; the length of the line from each first through hole 811 to the second through hole 821 is the same.

[0071] To ensure uniformity of airflow distribution, the main airway 830 and at least two branch airways A840 are designed such that the airflow path from the second through-hole 821 to each first through-hole 811 is of the same length, so as to achieve synchronous inflation and deflation of different massage subjects and achieve better results.

[0072] In one embodiment, the number of interfaces 6 with the same number on different plug sockets 4 is at least two.

[0073] Furthermore, the condition that the number of interfaces 6 with the same number must meet is that when the gas flow rate through connector 5 is at its minimum, the gas flow rate through interface 6 can meet the working requirements of the equipment.

[0074] The requirement for using the equipment is that inflation or deflation can be completed within a set time.

[0075] As the number of devices increases, the number of plug sockets 4 also increases. Thus, during inflation, air enters through one connector 5 and exits through multiple ports 6 with the same number after being split. As a result, the inflation and deflation time of the device increases while the inflation and deflation pressure of the inflation device 15 remains unchanged. When the device is a massager, it needs to alternate between inflation and deflation in a short time. Therefore, while minimizing the volume of the gas splitting device, the number of devices and plug sockets 4 must be sufficient to meet the working requirements of the devices so that inflation and deflation can be completed within the set time.

[0076] In one embodiment, if the number of plug sockets 4 P3 remains unchanged, and the number of interfaces 6 on each plug socket 4 P2 increases and becomes even, the number of shunt layers 7 P1 and the number of interfaces 6 on each plug socket 4 P2 are related as follows:

[0077] P2 = 2P1;

[0078] If the number of plug sockets 4, P3, remains unchanged, and the number of interfaces 6 on each plug socket 4, P2, increases and becomes an odd number, the number of shunt layers 7, P1, and the number of interfaces 6 on each plug socket 4, P2, have the following relationship:

[0079] P2-1 = 2P1;

[0080] If the number of interfaces 6 on each plug socket 4 remains unchanged (P2), and the number of plug sockets 4 (P3) increases, then, provided that the gas flow through the interfaces 6 can meet the working requirements of the equipment, the number of branch channels A840 of the secondary diversion channel 8 (P4) is increased, and P4 = P3.

[0081] This embodiment provides a preferred design method for the number of flow dividers 7 and interfaces 6, which is designed by using the number of devices and the air path;

[0082] If the number of devices remains the same, but the number of gas paths for each device is increased (i.e., the number of plug sockets 4 P3 remains the same, but the number of interfaces 6 on each plug socket 4 increases), it is necessary to first determine whether the number of interfaces 6 is even or odd. If it is even, the number of flow dividers 7 can be designed to be half the number of interfaces 6 on each plug socket 4, which can make full use of the space of the flow dividers 7 within its limited size. That is, two secondary flow dividers 8 can be set on each flow divider 7. If it is odd, the number of interfaces 6 is reduced by 1 to obtain an even number, and then divided by 2 to obtain the number of flow dividers 7. This can further utilize the space of the flow dividers 7 to reduce the volume of the gas flow divider device.

[0083] If the gas path of the equipment remains unchanged, but the number of equipment increases, the number of interfaces 6 on each plug socket 4 remains unchanged, while the number of plug sockets 4, P3, increases. This requires adding branch airways A840 to the secondary split airway 8. When adding branch airways A840, it is necessary to consider whether the gas flow rate through the interface 6 can meet the working requirements of the equipment. If it can, the number of branch airways A840 can be increased. If it cannot, the cross-sectional area of ​​the secondary split airway 8 and the cross-sectional area of ​​the connector 5 need to be increased to improve the gas flow rate through the connector 5 and the secondary split airway 8 per unit time to meet the working requirements of the equipment.

[0084] like Figure 10 As shown, in one embodiment, it further includes: a primary diversion air passage 11 for connecting the inflation device 15 and the connector 5, wherein one side of the primary diversion air passage 11 is provided with an air inlet passage 12 connected to the inflation device 15, and the other side is provided with an air outlet passage 13 connected to the connector 5, wherein the number of air outlet passages 13 is the same as the number of connectors 5; and the solenoid valve is provided on the air outlet passage 13.

[0085] During use, the airflow needs to be diverted to each outlet 13 after passing through the inlet duct 12. The gas flow rate of each outlet 13 is controlled by a solenoid valve. The inflation device 15 will circulate to inflate and deflate the device. At the beginning of inflation, the instantaneous flow rate through the inlet duct 12 will increase rapidly, which will impact the outlet 13 connected between the inflation device 15 and the connector 5, causing fluctuations and affecting the user experience. Therefore, a primary diversion airway 11 is set at the connection, which can buffer the airflow entering from the inlet duct 12 and also serve as a diversion function.

[0086] like Figures 11-12 As shown, the primary diversion airway 11 further includes: a third airway 111, a fourth airway 112, a fifth airway 113 and a sixth airway 114 arranged sequentially from the inside to the outside;

[0087] One end of the third air passage 111 is connected to the air intake passage 12, and the other end is connected to the fourth air passage 112;

[0088] The fourth airway 112 is formed by a plurality of branch airways B1121 distributed circumferentially, and each of the plurality of branch airways B1121 is connected to the end of the third airway 111 away from the air intake 12.

[0089] The fifth airway 113 is formed by a plurality of branch airways C1131 spaced apart along the axial direction. The branch airways C1131 are annular airways, and the number of branch airways C1131 is the same as the number of air outlets 13. The number of branch airways C1131 is the same as the number of branch airways B1121, or the number of branch airways B1121 is a multiple of the number of branch airways C1131. The branch airways C1131 are connected to the corresponding number of branch airways B1121.

[0090] For example, if there are 8 branch airways B1121 and 4 branch airways C1131, then one branch airway C1131 is connected to two branch airways B1121. If the number of both is the same, then they are connected one-to-one.

[0091] The sixth airway 114 is formed by a plurality of branch airways D1141 distributed at intervals along the axial direction. The branch airways D1141 are annular airways. The number of branch airways D1141 is the same as the number of air outlets 13, and they are interconnected. The plurality of branch airways D1141 are respectively connected to the plurality of branch airways C1131, and the connection position between the two is set away from the air outlet 13.

[0092] The third air passage 111 is connected to the intake passage 12, and the connection between the two forms a buffer chamber, which can reduce the instantaneous impact force. Then, the airflow flows from the third air passage 111 to the other end of the first-stage diversion air passage 11, and then is evenly distributed into each branch air passage B1121 of the fourth air passage 112, flowing along the axial direction of the fourth air passage 112, and then flowing into the fifth air passage 113. The airflow flows radially into the fifth air passage 113, and impacts the side wall of the fifth air passage 113 to form a buffering effect. Then it enters the sixth air passage 114, and is buffered again. Finally, the airflow is stably discharged from the exhaust passage 13, reducing the impact on the exhaust passage 13. Through the above technical solution, the first-stage diversion air passage 11 can buffer and divert the airflow entering from the intake passage 12, so that the airflow entering the exhaust passage 13 is stable and will not impact the subsequent air passages, reduce the impact force on the connection of various components, prevent air leakage, and improve service life.

[0093] Additionally, to prevent excessive massage intensity from causing injury to body parts and affecting the user experience, such as... Figure 13 As shown, a safety air passage 14 is provided on one side of the air outlet 13. The safety air passage 14 is located upstream or downstream of the solenoid valve. The safety air passage 14 is a continuous Z-shape. One end of the safety air passage 14 is provided with at least two exhaust passages A141 that communicate with the air outlet 13, and the other end is provided with at least two exhaust passages B142 that communicate with the outside. The inner diameter of the safety air passage 14 is equal to or less than one-tenth of the inner diameter of the air outlet 13.

[0094] When the air pressure in the outlet duct 13 exceeds the safe operating range, the safety duct 14 will exhaust air outwards. The airflow will enter from the exhaust duct A141, pass through the continuous Z-shaped safety ducts 14, and then exit from the exhaust duct B142. When the air pressure in the outlet duct 13 is within the normal operating range, the safety duct 14 will not exhaust gas or will exhaust only a small amount of gas. This is because the inner diameter of the safety duct 14 is small. After the airflow enters the safety duct 14, it will continuously impact the continuous Z-shaped safety ducts 14, resulting in very small exhaust airflow and air pressure. Therefore, when the air pressure in the outlet duct 13 is within the safe operating range, it will not exhaust from the safety duct 14, or will exhaust very little. When the air pressure in the outlet duct 13 exceeds the safe operating range, the air pressure in the outlet duct 13 will also be slowly released. This ensures the normal use of the equipment and guarantees the safety of use, preventing injury to the human body and improving the user experience.
