Description

Intelligent massage mattress control system, control method and intelligent massage mattress Technical Field

[0001] The present invention relates to the field of bedding, and in particular to a control method and control system of an intelligent massage mattress and an intelligent massage mattress. Background Art

[0002] Massage, a common way to relieve stress and promote blood circulation, is popular among consumers. To facilitate massage during rest and sleep, mattresses are being integrated with massage functions. By incorporating massage airbags into mattresses, not only can rest and sleep time be fully utilized for massage, adapting to a fast-paced lifestyle, but it can also provide a full-body massage, offering a more thorough relaxation experience and greater comfort. This can also reduce muscle strain and promote overall health.

[0003] Various types of massage mattresses exist, each using different mechanisms to achieve its massage function. One common mechanism uses massage airbags to provide a massage effect. These mattresses typically use an air pump to inflate the airbags, and then adjust the massage intensity by controlling the pump's exhaust speed or allowing the airbags to naturally deflate. However, this mechanism presents the following issues:

[0004] First, because massage needs vary from person to person, users may need to select different massage modes in different scenarios. Massage modes include: massage with different massage frequencies (such as fast high-frequency massage, slow and even massage, variable speed massage, etc.), or massage modes with different height differences of massage airbags (such as large-amplitude massage, small-amplitude massage, variable-amplitude massage, etc.). However, existing technologies make this difficult to achieve.

[0005] Secondly, existing massage mattresses have certain problems with air exhaust. Due to the size and structural limitations of the massage airbags, existing massage mattresses may not be able to completely expel the air inside the massage airbags during exhaust, affecting the sleeping feel of the mattress. The massage airbags are also prone to making unusual noises when turning over on the mattress, affecting sleep quality. Summary of the Invention

[0006] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and provide an intelligent massage mattress control method, a control system and an intelligent massage mattress. The control system is set to cooperate with the intelligent massage mattress, and the control method of the intelligent massage mattress is changed to inflate the massage airbags, or exhaust them by suction or natural exhaust, or a combination of methods. The exhaust speed of the massage airbags is not only controllable, but also can be exhausted thoroughly, avoiding abnormal noises during use of the mattress. At the same time, massage modes are added. Only through the exhaust mode, the intelligent massage bed can form at least three massage modes, thereby improving the massage effect and applicability of the intelligent massage mattress.

[0007] The above technical objectives of the present invention are mainly solved by the following technical solutions:

[0008] The present invention relates to a technical solution for the first technical subject: an intelligent massage mattress control system, characterized in that it includes a control module, an inflation / deflator module connected to the massage airbag via an air path, the inflation / deflator module being electrically and signal-connected to a control module, the inflation / deflator module being used to inflate or deflate the massage airbag, causing the massage airbag to be inflated or deflated by a vacuum, and the control module causing the massage airbag to selectively or simultaneously perform the vacuum deflation and natural deflation. The control system controls the massage airbags in the intelligent massage mattress, and is used to inflate, deflate, or deflate the massage airbags by a vacuum or natural deflation, or a combination thereof, so that the deflation speed of the massage airbags is not only controllable, but also exhausts the air thoroughly and completely, avoiding the situation where the massage airbags have too much gas that cannot be discharged, thereby helping to prevent abnormal noises from the massage airbags during use of the mattress. Furthermore, by controlling the exhaust speed of the massage airbags and selecting different exhaust modes (such as extraction, natural exhaust, and a combination of extraction and natural exhaust), different massage modes can be created. This helps expand the range of massage modes available on the smart massage mattress, improving its massage effect and applicability. When only the massage airbags are being exhausted, without other functional requirements (such as exhaust speed, complete exhaust, or massage effect), the energy-saving natural exhaust mode can be used, contributing to energy conservation and emissions reduction.

[0009] As a further improvement and supplement to the above technical solution, the present invention employs the following technical measures: the inflation and degassing module includes an air pressure sampling unit electrically and signal-connected to the control module, an air pump drive unit, a solenoid valve drive unit, an air pump electrically and signal-connected to the air pump drive unit, and a first set of solenoid valves and a second set of solenoid valves electrically and signal-connected to the solenoid valve drive unit. The first and second sets of solenoid valves are connected via an air circuit, the first set of solenoid valves being connected to the air pump, and the second set of solenoid valves being connected to the massage airbags. The control module is a microcontroller unit, electrically and signal-connected to the air pump drive unit and the solenoid valve drive unit. The air pressure sampling unit samples the air pressure of the massage airbags through the air circuit or directly samples the air pressure of the massage airbags. Using the air pressure sampling unit to sample the air pressure of the massage airbags facilitates the control system to timely adjust the air pressure of the massage airbags to suit the weight of the user on the smart massage mattress and meet the user's massage needs. The first and second sets of solenoid valves work together to inflate or degas the massage airbags; using the second set of solenoid valves alone allows for natural degassing.

[0010] The technical solution of the second technical subject of the present invention: an intelligent massage mattress control method, which applies the above-mentioned intelligent massage mattress control system, and its control steps include: setting massage parameters; controlling the gas volume, inflation speed, and exhaust speed in the massage airbag through the inflation and exhaust modules, combined with the natural exhaust of the massage airbag, to achieve massage control and exhaust mode control. The massage parameters include the user's own parameters and the intelligent massage mattress parameters, wherein the user's own parameters mainly include: gender, age, height, weight and other parameters; the intelligent massage mattress parameters mainly include: massage mode M, massage height H and massage time T and other parameters. The exhaust mode in this technical solution is the above-mentioned exhaust mode, natural exhaust mode, and a mixed exhaust mode composed of exhaust and natural exhaust.

[0011] Preferably, when performing a suction-type exhaust, the air pump is controlled to operate, and the first and second sets of solenoid valves are energized, so that a first exhaust air path formed by the air pump, the first and second sets of solenoid valves are connected, and the massage airbags are exhausted through the first exhaust air path, thus performing a suction-type exhaust. When the air pump is operated, the gas within the massage airbags passes through the first and second sets of solenoid valves and the air path, is pumped out by the air pump, and finally is exhausted to the outside space through the exhaust port of the first set of solenoid valves, completing the entire suction-type exhaust process.

[0012] Preferably, when natural exhaust is desired, the air pump is controlled to stop, and the first and second sets of solenoid valves are de-energized, allowing the second exhaust air path formed by the second set of solenoid valves and the massage airbags to be exhausted, resulting in natural exhaust. When the first and second sets of solenoid valves are de-energized, the first and second sets of solenoid valves are disconnected, and the passage on the second set of solenoid valves that directly exhausts to the outside world is opened, allowing the gas inside the massage airbags to be exhausted to the outside world through the second set of solenoid valves.

[0013] Preferably, when inflating the massage airbag, the air pump, the first set of solenoid valves, and the second set of solenoid valves are controlled to operate, so that the inflation air path formed by the air pump, the first set of solenoid valves, and the second set of solenoid valves are connected, thereby inflating the massage airbag. During operation, the air pump initially draws gas from the outside through the air inlet connected to the outside by the first set of solenoid valves, and then fills the massage airbag with the gas drawn from the outside through the first set of solenoid valves, the second set of solenoid valves, and the associated air path, completing the inflation process.

[0014] As a preference, in order to facilitate users to set massage relaxation according to their own conditions and preferences, the massage height H of the massage airbag is set, and the maximum working pressure P of the massage airbag is set according to the massage height H. max [N], the single cycle inflation and exhaust working time TK of the massage airbag:

[0015] TK = K1×T1+K2×T2+K3×T3, where T1 is the single inflation time, T2 is the single exhaust time, and T3 is the single natural exhaust time. K1, K2, and K3 are corresponding coefficients, K1, K2, and K3∈[0,1], so that the massage mode includes at least three modes. Mode 1 is cyclic inflation and natural exhaust, where K1=1, K2=0, and K3=1; Mode 2 is cyclic inflation and exhaust by exhaust, where K1=1, K2=1, and K3=0; Mode 3 is formed by a random combination of Mode 1 and Mode 2.

[0016] Preferably, when the massage time reaches T or the massage operation is turned off, the inflation and exhaust module starts the exhaust to completely exhaust the massage airbag.

[0017] The third technical theme of the present invention relates to a technical solution: an intelligent massage mattress comprising an outer cover, a massage airbag disposed within the outer cover, and a comfort layer disposed above the massage airbag. The mattress also includes the aforementioned intelligent massage mattress control system, wherein the inflation / deflator module is used to inflate or deflate the massage airbag, causing the massage airbag to inflate or deflate by vacuum, and the control module causes the massage airbag to selectively or simultaneously perform vacuum exhaust and natural exhaust. The inflation / deflator module is configured for vacuum exhaust, which can completely evacuate the massage airbag and prevent residual gas from forming within the massage airbag, thereby preventing abnormal noise from the mattress during use. Furthermore, the vacuum exhaust and natural exhaust can operate independently or in conjunction, increasing not only the massage modes of the massage airbag but also the massage effect, thereby broadening the user base and improving the applicability of the intelligent massage mattress.

[0018] Preferably, in order to be able to massage more parts of the body, the massage airbags are layered, including at least a head area, a shoulder and back area, a buttocks area, and a leg area for supporting the user's head, shoulders and back, buttocks, and legs, respectively. The second group of solenoid valves comprises at least four solenoid valves, and the A port on each solenoid valve is connected to the head area, the shoulder and back area, the buttocks area, and the leg area through a corresponding air pipe. The T port on each solenoid valve cooperates with the external space, and the P port on each solenoid valve is connected to the P port of each solenoid valve on the first group of solenoid valves.

[0019] The first group of solenoid valves includes at least a first solenoid valve and a second solenoid valve, the A port of the first solenoid valve is connected to the air inlet of the air pump, the P port of the first solenoid valve is connected to the P port of each solenoid valve in the second group of solenoid valves, and the T port of the first solenoid valve cooperates with the external space; the A port of the second solenoid valve is connected to the air outlet of the air pump, the P port of the second solenoid valve is connected to the P port of each solenoid valve in the second group of solenoid valves, and the T port of the second solenoid valve cooperates with the external space.

[0020] The present invention has the following beneficial effects: 1. It satisfies the user's output selection in different massage application scenarios. Through the intelligent massage mattress control system and method with dual functions of air pump suction and natural exhaust, it can select the natural exhaust mode for a strong experience and the air pump suction control mode for uniform rhythmic output according to the user's needs. 2. Through the air pump suction mode, the massage airbag is completely exhausted, avoiding abnormal noise during use, and improving the user's comfort and experience. 3. The air pump suction mode stops working and the natural exhaust mode is adopted to achieve energy saving, which is conducive to improving energy utilization efficiency and reducing energy consumption.

Modes for Carrying Out the Invention

[0028] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0029] Example 1: The technical solution of the first technical theme of the present invention:

[0030] As shown in Figures 1 and 2, the intelligent massage mattress control system includes a control module, an inflation and exhaust module connected to the massage airbag L400 through an air path, the inflation and exhaust module forming an electrical and signal connection with a control module, the inflation and exhaust module being used to inflate or exhaust the massage airbag L400, so that the massage airbag L400 is inflated or exhausted by exhaust, and the control module enables the massage airbag L400 to selectively perform either the exhaust by exhaust or the natural exhaust of the massage airbag L400 or simultaneously perform the exhaust by exhaust.

[0031] In the present technical solution, the massage airbag L400 in the intelligent massage mattress is controlled by a control system, which is used to inflate the massage airbag L400, or to select one or a combination of exhaust modes such as vacuum exhaust and natural exhaust, so that the exhaust speed of the massage airbag L400 is not only controllable, but also the exhaust can be thorough and complete, avoiding the situation where there is too much gas in the massage airbag L400 that cannot be discharged, which is beneficial to avoid abnormal noise from the massage airbag L400 during the use of the mattress.

[0032] In addition, by controlling the exhaust speed of the massage airbag L400 and selecting different exhaust modes (such as suction exhaust mode, natural exhaust mode, and a mixed exhaust mode consisting of suction exhaust and natural exhaust), different massage modes can be formed, which is beneficial to increase the massage modes of the smart massage mattress and improve the massage effect and applicability of the smart massage mattress.

[0033] When only exhausting the massage airbag L400 is required without other functional requirements (such as exhaust speed, whether all the gas is exhausted, massage effect, etc.), the natural exhaust mode that does not require electricity can be used, which is beneficial to energy saving and emission reduction.

[0034] Further, the inflation and exhaust module includes an air pressure sampling unit L8006 electrically and signal-connected to the control module, an air pump drive unit L8004, a solenoid valve drive unit L8005, an air pump L8007 electrically and signal-connected to the air pump drive unit L8004, a first group of solenoid valves and a second group of solenoid valves electrically and signal-connected to the solenoid valve drive unit L8005, the first group of solenoid valves and the second group of solenoid valves are connected through an air circuit, the first group of solenoid valves is connected to the air pump L8007, and the second group of solenoid valves is connected to the massage airbag L400, the control module is a microcontroller unit L8000, and is electrically and signal-connected to the air pump drive unit L8004 and the solenoid valve drive unit L8005, the air pressure sampling unit L8006 adopts or directly samples the air pressure of the massage airbag L400 through the air circuit.

[0035] The air pressure sampling unit L8006 uses the massage airbag L400 to monitor air pressure, enabling the control system to adjust the air pressure in the massage airbag L400 to suit the user's weight and massage needs. The first and second solenoid valves work together to inflate or deflate the massage airbag L400; using the second solenoid valve alone allows for natural deflation.

[0036] In actual application, the control system also includes a power supply unit, a storage unit and a wireless communication unit. The power supply unit is used to power the control module and / or the inflation and exhaust modules. The storage unit and the wireless communication unit are both communicatively connected to the control module.

[0037] In order to improve the integration of the control system, the power supply unit, storage unit, wireless communication unit, air pump drive unit L8004, solenoid valve drive unit L8005, and air pressure sampling unit L8006 (often an air pressure sensor in actual applications) are integrated on the circuit board. Then, the circuit board, air pump L8007 and solenoid valve are set in the control box 4, that is, the control system is set in the control box 4.

[0038] Example 2: The technical solution of the second technical theme of the present invention:

[0039] As shown in Figures 2 to 5, the intelligent massage mattress control method uses the intelligent massage mattress control system described in Example 1, and its control steps include: setting massage parameters; controlling the gas volume, inflation speed, and exhaust speed in the massage airbag L400 through the inflation and exhaust modules, combined with the natural exhaust of the massage airbag L400, to achieve massage control and exhaust mode control.

[0040] Massage parameters include user parameters and smart massage mattress parameters. User parameters primarily include gender, age, height, and weight, while smart massage mattress parameters primarily include massage mode M, massage height H, and massage time T. The exhaust modes used in this technical solution include the extraction exhaust mode, natural exhaust mode, and a hybrid exhaust mode combining extraction and natural exhaust, as disclosed in Example 1. This hybrid exhaust mode creates a wider range of massage modes, meeting users' higher massage requirements and enabling wider adoption, thereby enhancing the mattress's competitiveness.

[0041] When vacuum-type exhaust is performed, the air pump L8007 is controlled to work, the first group of solenoid valves (including solenoid valve L80086 (also referred to as the first solenoid valve L80086) and solenoid valve L80085 (also referred to as the second solenoid valve L80085)) and the second group of solenoid valves (including solenoid valve L80081, solenoid valve L80082, solenoid valve L80083, and solenoid valve L80084) are energized, so that the first exhaust air path formed by the air pump L8007, the first group of solenoid valves and the second group of solenoid valves are connected, and the massage airbag L400 is exhausted through the first exhaust air path, which is vacuum-type exhaust (or called vacuum deflation).

[0042] As shown in Figure 2, the air pump L8007 starts working, the A port of the first solenoid valve is connected to the air inlet of the air pump L8007, the AP channel in the first solenoid valve is opened, and the PT and AT channels are closed; the A port of the second solenoid valve is connected to the air outlet of the air pump L8007, the AP and AT channels in the second solenoid valve are opened, and the PT channel is closed; the P ports on all the solenoid valves in the second group of solenoid valves are connected to the P port of the first solenoid valve, and the A ports on all the solenoid valves are respectively connected to the air inlet and outlet of each area on the massage airbag L400, the AP channel in each solenoid valve in the second group of solenoid valves is opened, and the PT and AT channels are closed; finally, the gas in each area on the massage airbag L400 is discharged through the corresponding air inlet and outlet, and passes through all the solenoid valves in the second group of solenoid valves, the first solenoid valve, the air pump L8007, and the second solenoid valve in turn, and finally is exhausted to the external space through the T port on the second solenoid valve.

[0043] When exhausting naturally, the air pump L8007 is controlled to stop working, and the first and second groups of solenoid valves are controlled to be de-energized, so that the second exhaust gas path formed by the second group of solenoid valves and the massage airbag L400 is exhausted, which is natural exhaust (or natural deflation).

[0044] Specifically, the gas in each area on the massage airbag L400 is discharged through the corresponding air inlet and outlet, enters the A port on all the solenoid valves in the second group of solenoid valves, passes through the AT channel in all the solenoid valves in the second group of solenoid valves, and is exhausted to the external space from the T port on all the solenoid valves in the second group of solenoid valves.

[0045] When inflating the massage airbag L400, the air pump L8007 and the solenoid valve group L8008 (the solenoid valve group L8008 includes a first group of solenoid valves and a second group of solenoid valves, and the first group of solenoid valves includes a first solenoid valve L80086 and a second solenoid valve L80085) are controlled to work so that the inflation air path formed by the air pump L8007, the first group of solenoid valves and the second group of solenoid valves are connected to inflate the massage airbag L400.

[0046] The process of inflating the massage airbag L400 is the reverse process of the vacuum exhaust. Specifically, the air pump L8007 starts working, the A port of the first solenoid valve L80086 is connected to the air inlet of the air pump L8007, the AT channel in the first solenoid valve L80086 is opened, and the PT and AP channels are closed; the A port of the second solenoid valve L80085 is connected to the air outlet of the air pump L8007, the AP channel in the second solenoid valve L80085 is opened, and the PT and AT channels are closed; the P ports on all the solenoid valves L80081-L80084 in the second group of solenoid valves are connected to the P port of the first solenoid valve L80086, and the A ports on all the solenoid valves L80081-L80084 in the second group of solenoid valves are respectively connected to the air inlet and outlet of each area on the massage airbag L400, and each solenoid valve L80081-L80084 in the second group of solenoid valves are connected to the air inlet and outlet of each area on the massage airbag L400. The AP channel in L80084 is opened, and the PT and AT channels are closed; the gas drawn into the external space through the A port of the first solenoid valve L80086 passes through the air pump L8007, the AP channel in the second solenoid valve L80085, the PA channels in each solenoid valve L80081-L80084 in the second group of solenoid valves, and finally the gas in each area on the massage airbag L400 is sucked in through the corresponding air inlet and outlet to complete the inflation process.

[0047] In order to facilitate users to set the appropriate massage mode, massage frequency and massage intensity, the massage height H of the massage airbag L400 is set, and the maximum working pressure Pmax [N] of the massage airbag L400 is set according to the massage height H. The single cycle inflation and exhaust working time TK of the massage airbag L400 is:

[0048] TK = K1×T1+K2×T2+K3×T3, where T1 is the single inflation time, T2 is the single exhaust time, and T3 is the single natural exhaust time. K1, K2, and K3 are corresponding coefficients, K1, K2, and K3∈[0,1], so that the massage mode includes at least three modes. Mode 1 is cyclic inflation and natural exhaust, where K1=1, K2=0, and K3=1; Mode 2 is cyclic inflation and exhaust by exhaust, where K1=1, K2=1, and K3=0; Mode 3 is formed by a random combination of Mode 1 and Mode 2.

[0049] When the massage time reaches T or the massage operation is turned off, the inflation and exhaust module starts the exhaust mode to completely exhaust the massage airbag L400.

[0050] As shown in FIG3 , in order to explain the above technical solution in more detail and further improve the above technical solution to fully reflect the improvement of the technical solution, another description method is used:

[0051] S100. User personal information and mattress massage parameter settings:

[0052] Preferably, after the system is powered on, the user can set personal information and mattress massage parameters through the UI interactive interface. A schematic diagram of user information and massage parameter settings is shown in FIG6 . User personal information primarily includes information such as gender, age, height, and weight; mattress massage parameter settings primarily include parameters such as massage mode M, massage height H, and massage time T. After completing the settings, the process proceeds to S200 .

[0053] S200, combining the cloud user's BMI and the air pressure intensity mapping model database, determining the maximum massage working air pressure Pmax [N] corresponding to the height of each area on the massage airbag L400 (including at least four areas, namely the head area L4001, the shoulder and back area L4002, the hip area L4003, and the leg area L4004);

[0054] Once the user's personal information and mattress massage parameters are set, the control system uploads the relevant parameters to the cloud via the wireless communication unit. Using the cloud-based database of user BMI and air pressure intensity mapping models, the control system determines the maximum massage operating air pressure Pmax[N] corresponding to the air spring massage height H for each zone. Jump to S300.

[0055] S300, start mattress massage:

[0056] As shown in FIG3 , in order to facilitate the process installation of the control box 4, the air pump L8007 is an air pump or air pump assembly with an air extraction function, the second solenoid valve L80085 and the first solenoid valve L80086 are two two-position three-way integrated solenoid valves, the solenoid valves L80081, L80082, L80083 and L80084 in the second group of solenoid valves are four two-position three-way integrated solenoid valves, and all the solenoid valves L80081~L80084 in the first and second groups of solenoid valves are L80086, air pump L8007, air pressure sensor group L8009 (which includes air pressure sensor L80091, air pressure sensor L80092, air pressure sensor L80093, air pressure sensor L80094) and various areas on the massage airbag L400 (including head area L4001, shoulder and back area L4002, hip area L4003, leg area L4004) are all connected by air pipes.

[0057] Inflation process: The microcontroller unit L8000 (i.e., the control module) simultaneously controls the first solenoid valve L80086 to be powered off, controls the air pump L8007 to be powered on, controls the second solenoid valve L80085 to be powered on, and controls the solenoid valves L80081 to L80084 on the second group of solenoid valves to be powered on. The air inlet A (i.e., port A) and the air outlet P (i.e., port P) of the first solenoid valve L80086 are disconnected, and the air inlet A and the air release port T (i.e., port T) are connected. The air inlet A and the air outlet P of the first solenoid valve L80086 are disconnected, and the air inlet A and the air release port T are connected, thereby realizing the connection from the T port of the first solenoid valve L80086 to the A port, to the air inlet of the air pump L8007, to the air outlet of the air pump L8007, to the A port and P port of the second solenoid valve L80085, and then to the P port and A port of the solenoid valves L80081~L80084 on the second group of solenoid valves, and finally inflating the four partitions L4001~L4004 on the massage airbag L400 through the A port of the solenoid valves L80081~L80084 on the second group of solenoid valves.

[0058] Natural deflation process: the microcontroller unit L8000 controls the air pump L8007 to shut down. At the same time, the microcontroller unit L8000 controls the second solenoid valve L80085, the first solenoid valve L80086, and the solenoid valves L80081~L80084 on the second group of solenoid valves corresponding to the four partitions L4001~L4004 on the massage airbag L400 that need to be adjusted to cut off the power. The air inlet A and the corresponding air outlet P on the solenoid valves L80081~L80084 on the second group of solenoid valves are disconnected, and the air inlet A and the corresponding air outlet T are connected, so that the four partitions L4001~L4004 on the massage airbag L400 are naturally exhausted through the air outlet T of the solenoid valves L80081~L80084 on the second group of solenoid valves.

[0059] During the air pumping and deflation process, the microcontroller unit L8000 simultaneously controls the solenoid valves L80081-L80084 of the second group of solenoid valves corresponding to the four zones L4001-L4004 of the massage airbag L400 that need adjustment, energizes the first solenoid valve L80086, starts the air pump L8007, and de-energizes the second solenoid valve L80085. This disconnects the air inlet A and the air vent T of the first solenoid valve L80086, connecting the air inlet A to the air outlet P. The air inlet A and air outlet P of the second solenoid valve L80085 are disconnected, connecting the air inlet A to the air vent T. Thereby, the four partitions L4001~L4004 on the massage airbag L400 are exhausted through the A port to the P port of each solenoid valve L80081~L80084 on the second group of solenoid valves, to the P port and A port of the first solenoid valve L80086, to the air inlet of the air pump L8007, to the air outlet of the air pump L8007, and then to the A port and T port of the second solenoid valve L80085, thereby finally achieving the extraction and exhaustion of the gas in the four partitions L4001~L4004 on the massage airbag L400.

[0060] The air pressure sampling unit L8006 (such as an air pressure sensor) is connected between the solenoid valves L80081~L80084 on the second group of solenoid valves and the four partitions L4001~L4004 on the massage airbag L400 through an air pipe, and is used to collect and monitor the air pressure of the four partitions L4001~L4004 on the massage airbag L400 in real time, thereby achieving precise control of the inflation and deflation pressure of the four partitions L4001~L4004 on the massage airbag L400.

[0061] After the mattress massage is turned on, the system starts the cyclic charging and deflating massage process of the massage air spring according to the massage parameters set by the user, such as massage mode M, massage height H and massage time T.

[0062] FIG5 is a schematic diagram of the mattress massage mode working state, which includes: starting the inflation phase, K1=1, K2=0, K3=0, and inflating the massage air springs in the corresponding area according to the maximum massage working pressure Pmax[N] corresponding to the massage height H set by the user; the massage working phases include but are not limited to massage mode 1 (cyclic inflation + natural deflation, K1=1, K2=0, K3=1), massage mode 2 (cyclic inflation + vacuum deflation, K1=1, K2=1, K3=0), and massage mode 3 (cyclic inflation + natural deflation + vacuum mixed, i.e., a random combination of mode 1 and mode 2); ending the vacuum phase and jumping to S400.

[0063] S400: Determine if massage time T has arrived or the user has closed the massage process.

[0064] After the mattress massage is turned on, if the massage time T is reached or the user turns off the massage, the process jumps to S500; otherwise, the process jumps to S300.

[0065] S500, the mattress vacuum mode is turned on and stops after working for a while:

[0066] Set the time threshold TT. After the mattress starts working, repeat the above S100~S400 until the massage time T is reached or the user turns off the massage. Turn on the mattress vacuum mode and work for TT time to solve the problem that the massage airbag L400 cannot be completely deflated. Finally, the control system stops working.

The T port on each solenoid valve cooperates with the external space, and the P port on each solenoid valve is connected to the P port of each solenoid valve L80085 to L80086 on the first group of solenoid valves.

[0071] The A port of the first solenoid valve L80085 is connected to the air inlet of the air pump L8007, the P port of the first solenoid valve L80085 is connected to the P ports of each solenoid valve L80081~L80084 in the second group of solenoid valves, and the T port of the first solenoid valve L80085 cooperates with the external space; the A port of the second solenoid valve L80086 is connected to the air outlet of the air pump L8007, the P port of the second solenoid valve L80086 is connected to the P ports of each solenoid valve L80081~L80084 in the second group of solenoid valves, and the T port of the second solenoid valve L80086 cooperates with the external space.

[0072] In order to stably fix the massage airbag L400 , an upper fixing layer 5 and a lower fixing layer 6 are respectively arranged above and below the massage airbag L400 , and the comfort layer 3 is arranged above the upper fixing layer 5 .

[0073] In order to further improve the comfort and quality reliability of the intelligent massage mattress, an elastic support layer 7 is provided below the lower fixed layer 6 , and the control box 4 is provided on the elastic support layer 7 , which is also conducive to improving the protection of the control box 4 .

[0074] The comfort layer 3, the massage airbag L400, the upper fixing layer 5, the lower fixing layer 6, the elastic support layer 7 and the control box 4 are all arranged in the outer shell.
