Description

Technical Field

[0001] The invention relates to a massage mattress, in particular to an air mattress inflation and exhaust control method, a control system using the method and an intelligent air mattress. Background Art

[0002] Affected by the pace of life and long-term desk work, many people have lumbar problems, which lead to poor sleep or even insomnia. Through scientific and reasonable lumbar massage and hot compress before going to bed, it can effectively promote blood circulation in the waist, accelerate the discharge of harmful metabolites in the body, and then relieve waist fatigue, help users relax before going to bed, and ultimately achieve the effect of improving sleep quality. Some massage chairs or fascia guns on the market can relax and massage designated parts of the body, but users still need to move back to the mattress to sleep after the relaxation massage, and cannot fall asleep naturally in place without any intervention after the relaxation massage.

[0003] There are a few mattresses with massage functions on the market. These mattresses have built-in high-frequency vibration modules, which make the mattress vibrate as a whole or in part to achieve a massage effect. However, these massages are limited to the shoulders or calves, and the mattresses do not have air cushions at the waist. There are also some massage devices on the market that can massage the waist by cyclically inflating and deflating air bags. Such devices generally perform fixed-mode massages at the whole or in part, and cannot dynamically adjust the massage method according to the user's relaxation state before going to bed. For users, the effects of these fixed-mode waist relaxation massages are not ideal. Summary of the invention

[0004] The technical problems to be solved and the technical tasks proposed by the present invention are to address the problems that the existing massage mattresses with air bags cannot perform intelligent massage according to the different relaxation states of the user before going to bed and have poor relaxation effects. The present invention provides an air mattress inflation and exhaust control method and a control system and an intelligent air mattress using the method. The inflation and exhaust method and the corresponding control system and the intelligent air mattress can support and lift the user's calves before going to bed, so that blood can flow back and promote blood circulation, and at the same time perform a flexible and comfortable relaxing massage on the user's waist. The waist massage combined with lifting the calf can rotate the pelvis to enhance the comfort of the waist support, helping the user to relax before going to bed. During the massage process, the user's current relaxation state is judged by continuously detecting the pressure changes of the air bags at the leg position, and then the massage frequency and massage height of the waist air bags are intelligently adjusted according to different states to further relax the user until the massage ends automatically or the user ends it manually.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a method for controlling the inflation and exhaust of an air mattress, characterized in that:

[0006] Obtain the air pressure changes of the leg airbags;

[0007] Determine the user's relaxation state based on the changes in air pressure in the leg airbags;

[0008] The massage parameters of the waist airbag are adjusted according to the user's relaxation state.

[0009] During the massage process, the present invention detects the change in air pressure after the airbag at the leg position is compressed, and then judges the user's relaxation state based on the change in air pressure, and intelligently adjusts the massage parameters of the airbag at the waist position accordingly, so as to achieve a flexible and comfortable massage of the user's waist area, allowing the user to get an efficient and relaxing massage before going to bed. The massage parameters here include working parameters such as massage height and frequency. The massage height corresponds to the inflation height of the airbag, and the massage frequency corresponds to the inflation and exhaust frequency of the airbag. This is the existing technology of airbag massage. The leg airbag can lift the calf to promote blood circulation, and further cooperate with the waist airbag massage to rotate the pelvis to enhance the comfort of waist support.

[0010] Preferably, the air pressure change of the leg airbag is an air pressure oscillation value. Based on the comparison between the preset first threshold, the second threshold and the air pressure oscillation value, the range of the air pressure oscillation value is determined, and the user is determined to be in a relaxation state corresponding to the range; when the air pressure oscillation value of the leg airbag is greater than the second threshold, the user is determined to be in an active state; when the air pressure oscillation value of the leg airbag is between the first threshold and the second threshold, the user is determined to be in a shallow relaxation state; when the air pressure oscillation value of the leg airbag is less than the first threshold, the user is determined to be in a deep relaxation state. The air pressure oscillation value is used to represent the air pressure change of the leg airbag after being compressed, and the value is compared with two preset thresholds of different sizes. According to the comparison result, the air pressure oscillation value is determined to be between the two thresholds and on the left and right sides of the two thresholds. Three states of the user from excitement to calmness are defined: active state-shallow relaxation state-deep relaxation state.

[0011] Preferably, the acquisition of the air pressure oscillation value includes: sampling the air pressure value of the leg airbag multiple times within a time period; calculating the air pressure average value of the air pressure values ​​sampled multiple times by the leg airbag; calculating the difference between the air pressure value sampled each time by the leg airbag and the air pressure average value; taking the absolute value of the difference and then calculating the average value, and setting the average value as the air pressure oscillation value of the leg airbag, which can reflect the air pressure change of the leg airbag. The specific air pressure oscillation value is obtained by sampling the air pressure of the leg airbag multiple times within a set time period, first calculating the average air pressure value of all samples, and then comparing the air pressure value of each sample with the air pressure average value to calculate the difference, and finally taking the absolute value of all the differences and averaging them to obtain the air pressure oscillation value, which can reflect the average oscillation amplitude of the air pressure of the leg airbag within a time period.

[0012] Preferably, the massage parameters of the lumbar airbag are adjusted based on the relaxation state of the user; when the user is in an active state, the lumbar airbag adopts the first massage mode to maintain the original massage height and massage frequency; when the user is in a shallow relaxation state, the lumbar airbag adopts the second massage mode to reduce the massage height and massage frequency; when the user is in a deep relaxation state, the lumbar airbag adopts the third massage mode to reduce the massage height and massage frequency, and the reduction rate is greater than the reduction rate in the shallow relaxation state. In three different relaxation states, the waist airbags respond through three different massage modes. Among them, the first massage mode corresponding to the active state will keep the existing massage height and massage frequency unchanged. At this time, the user is not sensitive to the current massage height and massage frequency; the second massage mode and the third massage mode corresponding to the shallow relaxation state and the deep relaxation state respectively will reduce the massage height and massage frequency. At this time, the user is already sensitive to the massage height and massage frequency, and needs to reduce the massage height and massage frequency to adapt to the user's gradually relaxed physical state. At the same time, for the deep relaxation state that is more relaxed and more sensitive to massage height and massage frequency, the massage height and massage frequency of the third massage mode will decrease faster to avoid the higher values ​​of massage height and massage frequency affecting the relaxation state that the user has already entered.

[0013] Preferably, the air pressure value of the leg airbag is obtained, and the air pressure oscillation value is calculated; the massage mode of the waist airbag in the current time period is adjusted according to the air pressure oscillation value of the leg airbag in the previous time period; the massage of the waist airbag in the current time period is used to promote user relaxation, and the air pressure value of the leg airbag is continuously detected and obtained, and the massage mode of the next time period is adjusted to achieve a virtuous cycle. When working, the massage mode of the waist airbag in the current time period is adjusted based on the air pressure oscillation value in the previous time period, and the air pressure oscillation value in the current time period is used as the basis for adjusting the massage mode of the waist airbag in the next time period, and this is repeated to achieve a virtuous cycle of waist airbag adjustment, achieve a relaxing massage of the waist area, and help users relax before going to bed.

[0014] A control system using the method comprises:

[0015] The massage module is adjusted up and down through the inflation and exhaust control to perform massage operations on the user;

[0016] An acquisition module, used to monitor the air pressure in the airbag and obtain the air pressure oscillation value;

[0017] The control module compares the air pressure oscillation value with a preset threshold value and adjusts the massage mode instruction of the massage module according to the output of the comparison result;

[0018] The regulating module is used to receive instructions from the control module, control the inflation and exhaust of the massage module, and change the inflation height and inflation and exhaust frequency of the massage module.

[0019] During operation, the control module obtains the air pressure oscillation value from the acquisition module and compares it with the preset threshold to determine the user's relaxation state, and then sends instructions to the adjustment module based on the aforementioned comparison result, so that the adjustment module can perform appropriate inflation and exhaust control on the massage module. Finally, the massage module performs repeated lifting and lowering adjustments to achieve a relaxing massage for the user.

[0020] Preferably, the control system further comprises an input module for inputting preset parameters to the control module;

[0021] The acquisition module transmits the acquired air pressure oscillation value to the control module, the control module compares the air pressure oscillation value with a preset threshold value, and transmits an adjustment instruction to the regulation module according to the comparison result. The regulation module receives the instruction from the control module, controls the inflation and exhaust of the massage module, changes the inflation height and inflation and exhaust frequency of the massage module, and adjusts the massage height and massage frequency toward the target massage height and target massage frequency.

[0022] The input module allows users to adjust the preset parameters in the control module according to their respective needs. The control module compares the air pressure oscillation value sent by the acquisition module with the preset threshold value, and sends the corresponding adjustment instruction to the adjustment module according to different comparison results. The adjustment module then controls the inflation and exhaust of the massage module to achieve the purpose of changing the inflation height and inflation and exhaust frequency of the massage module, so as to achieve changes in the massage height and massage frequency that are close to the target values. The massage height and massage frequency here correspond to the inflation height and inflation and exhaust frequency, respectively.

[0023] An intelligent air mattress using the method comprises a mattress body, on which a massage component and a detection device are arranged, wherein the massage component comprises a waist airbag, a leg airbag and a control box for adjusting the operation of the waist airbag and the leg airbag arranged on the mattress body, wherein the control box independently controls the inflation and exhaust of the waist airbag and the leg airbag, and makes the inflation height and inflation and exhaust frequency of the waist airbag independently adjustable, and the inflation height of the leg airbag independently adjustable; the detection device comprises an air pressure sensor and a data processor, wherein the air pressure sensor is used to detect the air pressure values ​​of the waist airbag and the leg airbag and send them to the data processor, and the data processor receives the air pressure values, calculates the air pressure oscillation values ​​of the leg airbags and sends them to the control box.

[0024] The intelligent air mattress works through the cooperation of a massage component and a detection device, wherein the massage component includes independently adjustable waist airbags and leg airbags, and a control box that controls the inflation and exhaust of the waist and leg airbags; the detection device includes an air pressure sensor for detecting the air pressure value of the leg airbag and a data processor for processing the air pressure value data. The data processor obtains the air pressure value of the leg airbag, calculates the air pressure oscillation value and sends it to the control box. The control box determines the user's relaxation state based on the air pressure oscillation value, and then controls and adjusts the inflation height and inflation and exhaust frequency of the waist airbag to achieve a relaxing massage for the user.

[0025] Preferably, the control box includes a processor, an air pump and a solenoid valve. The processor can receive preset parameter instructions from the input terminal and the air pressure oscillation value from the data processor. The processor independently controls the start and stop of the air pump and the solenoid valve to inflate the leg airbag to a set height, and repeatedly inflate and exhaust the waist airbag to adjust the inflation height and inflation and exhaust frequency. The processor of the control box receives the preset parameter instructions from the input terminal and the air pressure oscillation value of the data processor, and after comparison and calculation, independently controls the start and stop of the air pump and the solenoid valve according to the result output instruction, and then controls the waist airbag to adjust the inflation height and inflation and exhaust frequency. The inflation height here corresponds to the massage height of the waist airbag, and the inflation and exhaust frequency corresponds to the massage frequency of the waist airbag. The leg airbag is inflated to the set height to lift the user's legs in order to detect the air pressure value and obtain the air pressure changes during the massage process.

[0026] Preferably, a heating sheet is provided at the waist airbag, and the processor can control the start and stop of the heating sheet to achieve temperature regulation. The heating sheet heats up when working, heats the waist area to promote blood circulation, and further enhances the relaxation effect of the waist. The heating sheet and the waist airbag work together to achieve a better relaxation effect before going to bed.

[0027] The beneficial effects of the present invention are as follows: the user's relaxation state is judged by utilizing the air pressure change of the airbag at the leg position after being compressed, and the massage parameters of the airbag at the waist position are intelligently adjusted accordingly, so as to perform a flexible and comfortable massage on the user's waist area, allowing the user to get an efficient and relaxing massage before going to bed. Furthermore, for the air pressure change of the airbag at the leg position, the air pressure oscillation value is calculated by sampling the air pressure value, and the air pressure oscillation value is used as an important indicator for correlating and evaluating the user's relaxation degree. Three different relaxation states are defined by using different results of comparing the indicator with a preset threshold value, and the massage height and frequency of the waist airbag are intelligently adjusted. The present invention provides an air mattress inflation and exhaust control method for achieving the aforementioned technical effects, as well as a control system and an intelligent air mattress using the method.

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Embodiment 1:

[0037] The present embodiment provides an air mattress inflation and exhaust control method, the method comprising obtaining the air pressure change of the leg airbags, then judging the user's relaxation state according to the air pressure change of the leg airbags, and then adjusting the massage parameters of the waist airbags according to the user's relaxation state. In the present embodiment, the massage parameters of the waist airbags include working parameters including massage height and frequency, the massage height corresponds to the inflation height of the airbag, and the massage frequency corresponds to the inflation and exhaust frequency of the airbag.

[0038] The specific air pressure change of the leg airbag is represented by the air pressure oscillation value. The air pressure oscillation value is calculated by the following steps: sampling the air pressure value of the leg airbag multiple times within a time period; calculating the air pressure average of the air pressure values ​​sampled multiple times by the leg airbag; calculating the difference between the air pressure value sampled each time by the leg airbag and the air pressure average; taking the absolute value of the difference and calculating the average value, and setting the average value as the air pressure oscillation value of the leg airbag. The air pressure oscillation value of the leg airbag can reflect the air pressure change of the leg airbag.

[0039] Specifically, the user's relaxation state is judged and the working parameters of the waist airbag massage are adjusted. According to the obtained air pressure oscillation value of the leg airbag in the previous time period, the air pressure oscillation value is compared with the preset first threshold and second threshold, and the range of the air pressure oscillation value is judged, and then the user is judged to be in the relaxation state corresponding to the range, and the massage mode of the waist airbag in the current time period is adjusted. When the air pressure oscillation value of the leg airbag is greater than the second threshold, the user is judged to be in an active state, and the waist airbag adopts the first massage mode to maintain the original massage height and massage frequency; when the air pressure oscillation value of the leg airbag is between the first threshold and the second threshold, the user is judged to be in a shallow relaxation state, and the waist airbag adopts the second massage mode to reduce the massage height and massage frequency; when the air pressure oscillation value of the leg airbag is less than the first threshold, the user is judged to be in a deep relaxation state, and the waist airbag adopts the third massage mode to reduce the massage height and massage frequency, and the reduction rate is greater than the reduction rate in the shallow relaxation state. During the current time period, the waist airbag massage promotes user relaxation, and continues to detect and obtain the air pressure value of the leg airbag, and calculates the air pressure oscillation value of the waist airbag during the current time period, and continues to compare the air pressure oscillation value with the first threshold and the second threshold to determine the user's relaxation state, and adjust the massage mode for the next time period, and repeat this process to achieve a virtuous cycle.

[0040] The control method of the present invention detects and obtains the air pressure value of the airbag at the leg position after being compressed, and calculates and obtains the air pressure oscillation value as an important indicator of the air pressure change, judges the user's relaxation state and intelligently adjusts the massage parameters of the airbag at the waist position accordingly, so as to achieve a flexible and comfortable massage of the user's waist area, allowing the user to get an efficient relaxation massage before going to bed. During the massage process, the leg airbag maintains the set inflation height to detect the air pressure change, and raising the calf can promote blood circulation. At the same time, the airbag cooperates with the relaxation massage of the waist area, and the pelvis is rotated to enhance the comfort of the waist support.

[0041] like Figure 1 and Figure 2 As shown, in actual operation, the method described in Example 1 includes the following stages performed in sequence:

[0042] The first stage S100. preset massage parameters, the massage parameters include support height, minimum massage frequency MIN_F and maximum massage frequency MAX_F, minimum massage height MIN_H and maximum massage height MAX_H, massage duration T, the support height and massage height are both in cm, the massage frequency is in Hz, and the massage duration is in min;

[0043] S101. Set the leg airbag inflation height HH. The leg airbag inflation has two main purposes: one is to ensure that the calf is in a lifted state during the user's waist massage relaxation process; the other is to keep the calf lifted during the waist massage relaxation process, so as to analyze the user's relaxation state by detecting the air pressure state change of the leg airbag. The preferred leg airbag inflation height is 8cm;

[0044] S102. Set the minimum massage frequency MIN_F and the maximum massage frequency MAX_F of the lumbar airbag of the mattress. The lumbar airbag massage frequency is generally suitable in the range of 0.1Hz to 1Hz. Preferably, the minimum massage frequency MIN_F = 0.1Hz and the maximum massage frequency MAX_F = 1Hz of the lumbar airbag;

[0045] S103. Set the minimum massage height MIN_H and maximum massage height MAX_H of the lumbar airbag of the mattress; if the massage height of the lumbar airbag is too small, it will not support the lumbar spine; if the height is too large, the lumbar spine will be too high and cause discomfort. The lumbar support height is suitable between 3 and 10 cm. The maximum inflation height is related to the power of the inflation pump and the physical structure size of the lumbar airbag. Preferably, the minimum massage height MIN_H of the lumbar airbag is 3 cm, and the maximum massage height MAX_H is 10 cm.

[0046] S104. Set the massage duration. Since the lumbar airbag massage has a certain lumbar traction effect, combined with the time reference of lumbar traction on medical equipment, the total massage time T is suitable for 15 to 30 minutes, and does not exceed 30 minutes, preferably T = 15 minutes;

[0047] After the massage parameters are set, the process proceeds to the second stage S200 for further execution.

[0048] The second stage S200. Start massage based on the preset massage parameters, the leg airbags are inflated to a support height of 8 cm, the waist airbags start to circulate inflation and exhaust at the maximum massage frequency MAX_F=1Hz, and the inflation height is the maximum massage height MAX_H=10cm to start working, and enter the third stage S300 to continue execution.

[0049] The third stage S300. Detect the air pressure change of the leg airbag, calculate the air pressure oscillation value within the set time period, judge the user's relaxation state based on the air pressure oscillation value and use it as a basis to intelligently adjust the massage parameters within the next set time period. The purpose of intelligent adjustment is to reduce the massage frequency from the maximum massage MAX_F to the minimum massage frequency MIN_F, and reduce the massage height from the maximum massage height MAX_H to the minimum massage height MIN_H. When the massage frequency and massage height are reduced to the set minimum value, they remain unchanged;

[0050] S301. The massage duration is divided into M relaxation state analysis time periods △T, △T = T / M, T is the massage duration, M is the set parameter; in the first time period △T, the waist airbag 1 starts working massage at the maximum massage frequency MAX_F and the maximum massage height MAX_H; set a single relaxation state analysis time period △T: △T = T / M;

[0051] The air pressure oscillation value △V is set to represent the oscillation change of the air pressure of the leg airbag relative to the average value. The air pressure values ​​of N leg airbags are continuously collected in each time period △T to calculate the corresponding air pressure oscillation value △V. The air pressure oscillation value △V represents the oscillation change of the air pressure of the leg airbag relative to the average value.

[0052] Calculate the average value AVG_V, AVG_V = (∑VN) / N; calculate the difference between the N sampled air pressure values ​​and the aforementioned air pressure average value, take the absolute value of the difference and then calculate the average value as the air pressure oscillation value in each time period, △V = ∑|VN-AVG_V| / N, N is a setting parameter, and in this embodiment, the setting parameters M = 15, N = 6; set thresholds TH_V1 and TH_V2, TH_V2>TH_V1> air pressure detection error; in each time period, based on the previous time period △T, N leg airbag air pressure values ​​V1~VN are continuously sampled with SAMP_T = △T / N as the sampling time interval, △T = 15min / 15 = 1min, SAMP_T = 1min / 6 = 10S;

[0053] S302. According to the obtained air pressure oscillation value △V of the previous time period △T, compared with the set thresholds TH_V1 and TH_V2, the user's relaxation state is determined, the waist airbag massage mode of the current time period is adjusted, and the massage frequency F and massage height H of the waist airbag are changed;

[0054] S3021. When △V>threshold TH_V2, it is determined that the user is in an excited active state (relaxed state 1). At this time, the user is in a relatively active state and is less sensitive to the frequency and height of the waist airbag massage. The massage frequency F and the massage height H maintain the corresponding values ​​of the previous time period △T unchanged;

[0055] S3022. When TH_V1≤△V≤TH_V2, it is determined that the user is in a transitional shallow relaxation state (relaxation state 2). At this time, the user is in a transitional stage from active to quiet. In this state, the massage frequency and massage height of the waist airbag gradually decrease to guide the user to a quiet state. The massage frequency F and massage height H are based on the parameters of the previous time period △T and decrease towards the minimum massage frequency MIN_F and the minimum massage height MIN_H;

[0056] In the light relaxation state, the massage frequency F decreases by a difference value △F1, △F1 = (MAX_F - MIN_F) / M, and the massage height H decreases by a difference value △H1, △H1 = (MAX_H - MIN_H) / M;

[0057] S3023. When △V < TH_V1, it is determined that the user is in a quiet deep relaxation state (relaxation state three). At this time, the user is already relatively quiet, and the user has a high sensitivity to the massage frequency and height of the lumbar airbag. After the massage frequency F and the massage height H decrease towards the minimum massage frequency MIN_F and the minimum massage height MIN_H based on the parameters of the previous time period △T, and the massage frequency F and the massage height H decrease more rapidly than in the light relaxation state;

[0058] In the deep relaxation state, the massage frequency F decreases by a difference value △F2, △F2 = K*(MAX_F - MIN_F) / M, and the massage height H decreases by a difference value △H2, △H2 = K*(MAX_H - MIN_H) / M, where K ≥ 2.

[0059] S303. The massage stops automatically when the massage duration T reaches the standard or is manually stopped by the user midway;

[0060] S304. The massage ends.

[0068] The acquisition module transmits the acquired air pressure oscillation value to the control module, the control module compares the air pressure oscillation value with a preset threshold value, and transmits an adjustment instruction to the regulation module according to the comparison result. The regulation module receives the instruction from the control module, controls the inflation and exhaust of the massage module, changes the inflation height and inflation and exhaust frequency of the massage module, and adjusts the massage height and massage frequency toward the target massage height and target massage frequency.
