[0002] In the existing massage machine, the circuit board controls the AC air pump to output a fixed duty cycle of the driving current to inflate the massage airbag, so its air flow, maximum air pressure, and power are all fixed and cannot be changed according to demand. In view of this, the present application is specially proposed. Summary of the invention

[0005] Step 1: Generate the target air pressure value of the massage airbag using the circuit board and start to inflate with the preset driving current frequency and duty cycle, detect the current air pressure value in the massage airbag in real time and calculate the growth rate of the current air pressure value;
[0006] Step 2: When the growth rate of the current air pressure value reaches the first inflection point and the current air pressure value is less than the target air pressure value, the duty cycle of the driving current is increased to increase the current air pressure value;

[0008] By adopting the above technical scheme, the present invention can achieve the following technical effects: compared with the prior art, the massage airbag adaptive inflation method uses a circuit board to generate a massage airbag target pressure value and starts inflation with a preset frequency and duty cycle of a driving current, and detects the current air pressure value in the massage airbag in real time and calculates the growth rate of the current air pressure value; when the growth rate of the current air pressure value has the first inflection point and the current air pressure value is less than the target air pressure value, the duty cycle of the driving current is increased to increase the current air pressure value; when the current air pressure value reaches the target air pressure value, the duty cycle of the driving current is reduced to maintain the pressure of the massage airbag. That is to say, the method of the present invention monitors the pressure value in the massage airbag in real time, and adjusts the duty cycle of the driving current for inflating the massage airbag, thereby controlling the air flow, maximum air pressure and output power of the AC air pump, so as to realize the adaptive inflation of the massage airbag, so that it can be applied to different use environments and improve the massage experience of the user.

[0017] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0018] like Figure 1 As shown, an embodiment of the present invention provides a massage airbag adaptive inflation method, which uses a circuit board to convert alternating current into a driving current to drive the movement of an inflation piston, thereby controlling the inflation degree of the massage airbag, and an air pressure detection device is provided in the massage airbag. The method includes:
[0019] Step 1: Generate the target air pressure value of the massage airbag using the circuit board and start inflating with the preset driving current frequency and duty cycle, detect the current air pressure value in the massage airbag in real time and calculate the growth rate of the current air pressure value.
[0020] Step 2: When the growth rate of the current air pressure value reaches the first inflection point and the current air pressure value is less than the target air pressure value, the duty cycle of the driving current is increased to increase the current air pressure value.
[0021] Step 3: When the current air pressure value reaches the target air pressure value, the duty cycle of the driving current is reduced to maintain the pressure of the massage airbag.
[0022] That is to say, the method of the present invention monitors the pressure value in the massage airbag in real time, and adjusts the duty cycle of the driving current for inflating the massage airbag, thereby controlling the air flow, maximum air pressure and output power of the AC air pump, so as to achieve adaptive inflation of the massage airbag, which can be applied to different usage environments and improve user experience.
[0023] It should be noted that increasing the duty cycle of the driving current increases the output power time of the driving current, that is, increases the inflation time of the maximum air pressure, which can reach the target air pressure value of the massage airbag faster and more stably. The influence of the driving current frequency on the inflation of the massage airbag is mostly in terms of noise. The biggest benefit of reducing the driving current frequency is to reduce noise, such as Figure 3 As shown in the figure, it is a schematic diagram of signals with different duty cycles at the same frequency.
[0024] It should be noted that in step 1, the growth rate of the current air pressure value can be determined by monitoring the changes in the air pressure values in the massage airbags detected by the air pressure detection device in multiple time periods. The first inflection point can be the first time that the air pressure value in the massage airbag does not increase and remains stable for a period of time.
[0025] The operation mode of holding pressure can be as follows: Figure 7 As shown, after entering the pressure maintaining mode, the frequency is first lowered to reduce noise, and the air pressure in the massage airbag is detected in real time to see if there is any change. If it increases, the frequency is kept lowered and the duty cycle is reduced to inflate the massage airbag. If it decreases, the frequency is kept higher and the duty cycle is increased to inflate the massage airbag. If there is no change, the frequency and duty cycle are maintained to inflate the massage airbag to maintain the pressure.
[0026] Furthermore, in one example, in order to reach the target air pressure value of the massage airbag faster and more stably while reducing noise to provide the user with a better massage experience, in step 2, the frequency of the driving current is reduced while increasing the duty cycle of the driving current.
[0027] Furthermore, in one example, in step 3, the frequency of the driving current is reduced while the duty cycle of the driving current is reduced, so that the massage airbag can be pressurized with minimal inflation noise and minimal output power of the driving current.
[0028] Furthermore, in one example, in step 2, the duty cycle of the driving current is first increased, and if the target pressure value is not reached within a predetermined time, the frequency of the driving current is reduced.
[0029] In this way, the massage airbag can be inflated with the fastest and most stable driving current. However, if the target air pressure value is not reached within the preset time, it means that the current air pressure value in the massage airbag has reached the air pressure critical value of the current frequency. Continuing to inflate the massage airbag at the current frequency will not reach the target air pressure value. At this time, the frequency of the current driving current needs to be reduced and the duty cycle remains unchanged to inflate the massage airbag.
[0030] Furthermore, in one example, in step 3, the frequency of the driving current is first reduced, and if the target air pressure value is not reached within a predetermined time, the duty cycle of the driving current is reduced. In this way, the most suitable inflation noise and the most suitable output power of the driving current can be achieved to maintain the pressure of the massage airbag.
[0031] Further, in one example, Figure 2 As shown, before step 1, the method further includes:
[0032] Step A: pre-set the target air pressure value of the massage airbag corresponding to each massage technique in the massage device and the frequency and duty cycle of the corresponding driving current.
[0033] It should be noted that massage equipment has many sets of massage techniques to meet the different needs of different users. For example, the elderly, young people, boys and girls have different requirements for the intensity and function of massage equipment, so the adapted massage techniques are also different. Correspondingly, different massage techniques correspond to different target air pressure values of the massage airbags and the corresponding frequency and duty cycle of the driving current. Therefore, pre-setting is required to better adaptively adjust the inflation effect of the massage airbag to be more suitable for different users and different usage environments.
[0034] The adaptive inflation method of the massage airbag of the present invention is described in detail below in conjunction with specific massage techniques. Of course, the massage techniques are not limited to the following ones, and similar adaptive inflation methods of the massage airbag are all within the protection scope of the present invention.
[0035] It should be noted that the massage technique includes at least a stretching or rapid inflation massage technique, a full-body inflation massage technique, and a shaking soothing sleep massage technique. Among them, the frequency and duty cycle of the driving current of the massage airbag corresponding to the stretching or rapid inflation massage technique are greater than the frequency and duty cycle of the driving current of the massage airbag corresponding to the full-body inflation massage technique, and the frequency and duty cycle of the driving current of the massage airbag corresponding to the full-body inflation massage technique are greater than the frequency and duty cycle of the driving current of the massage airbag corresponding to the shaking soothing sleep massage technique. Correspondingly, the target air pressure value of the massage airbag corresponding to the stretching or rapid inflation massage technique is greater than the target air pressure value of the massage airbag corresponding to the full-body inflation massage technique, and the target air pressure value of the massage airbag corresponding to the full-body inflation massage technique is greater than the target air pressure value of the massage airbag corresponding to the shaking soothing sleep massage technique.
[0036] Embodiment 1:
[0037] For example, Figure 4 As shown, when the current massage technique is stretching or rapid inflation massage technique,
[0038] Step 1: Generate the target air pressure value of the massage airbag using the circuit board and start inflating with the preset driving current frequency and duty cycle, detect the current air pressure value in the massage airbag in real time and calculate the growth rate of the current air pressure value. At this time, the massage airbag needs to be inflated quickly with high frequency and high duty cycle.
[0039] Step 2 can be specifically executed as follows: when the air pressure value in the massage airbag within a period of time reaches the air pressure critical value of the current frequency and cannot reach the target air pressure value, and increasing the duty cycle of the driving current can no longer increase the growth rate of the current air pressure value in the massage airbag, then reduce the frequency of the driving current and maintain the duty cycle of the driving current to inflate the massage airbag.
[0040] Step 3: When the current air pressure value reaches the target air pressure value, the duty cycle of the driving current is reduced to maintain the pressure of the massage airbag.
[0041] Embodiment 2
[0042] For example, Figure 5 , when the current massage technique is full body inflatable massage technique,
[0043] Step 1: Generate the target air pressure value of the massage airbag using the circuit board and start inflating with the preset driving current frequency and duty cycle, detect the current air pressure value in the massage airbag in real time and calculate the growth rate of the current air pressure value. At this time, the massage airbag needs to be inflated quickly with high frequency and high duty cycle.
[0044] Step 2 can be specifically executed as follows: when the air pressure value in the massage airbag within a period of time reaches the air pressure critical value of the current frequency and cannot reach the target air pressure value, reduce the current air pump operating frequency and increase the current air pump operating duty cycle to inflate the massage airbag.
[0045] Step 3: When the current air pressure value reaches the target air pressure value, the duty cycle of the driving current is reduced to maintain the pressure of the massage airbag.
[0046] Embodiment 3
[0047] For example, Figure 6 When the current massage technique is the shaking soothing massage technique, step 2 can be specifically executed as follows:
[0048] The air pressure value in the massage airbag is detected in real time. When the air pressure value has not reached the target air pressure value, it is determined whether the air pressure in the massage airbag changes within a period of time. If not, the frequency of the driving current is maintained and the duty cycle of the driving current is increased to inflate the massage airbag; if so, the trend of the air pressure change is determined. When the air pressure increases, the frequency of the driving current is reduced and the duty cycle of the driving current is maintained to inflate the massage airbag; when the air pressure decreases, the frequency of the driving current is maintained and the duty cycle of the driving current is increased to inflate the massage airbag.
[0049] Embodiment 4
[0050] For example, when the stretching or rapid inflation massage technique is switched to the shaking soothing sleep massage technique, the method further includes:
[0051] The frequency of the driving current and the duty cycle of the driving current are reduced, and the target air pressure value of the massage airbag corresponding to the shaking and soothing sleep massage technique is reconfigured, and then the massage airbag is inflated according to the inflation method corresponding to the aforementioned shaking and soothing sleep massage technique.
[0052] Embodiment 5
[0053] For example, when the shaking soothing massage technique or the full body inflating massage technique is switched to the stretching or rapid inflating massage technique, the method further includes:
[0054] Increase the frequency of the driving current and increase the duty cycle of the driving current, reconfigure the target air pressure value of the massage airbag corresponding to the stretching or quick inflation massage technique, and then inflate the massage airbag according to the inflation method corresponding to the aforementioned stretching or quick inflation massage technique.
[0055] Embodiment 6
[0056] For example, when the stretching or rapid inflation massage technique is switched to the full body inflation massage technique, the method further includes:
[0057] Reduce the frequency of the driving current and reduce the duty cycle of the driving current, reconfigure the target air pressure value for inflating the massage airbag corresponding to the whole-body inflation massage technique, and then inflate the massage airbag according to the inflation method corresponding to the aforementioned whole-body inflation massage technique.
[0058] That is to say, the method of the present invention monitors the pressure value in the massage airbag in real time, and adjusts the duty cycle of the driving current for inflating the massage airbag, thereby controlling the air flow, maximum air pressure and output power of the AC air pump, so as to achieve adaptive inflation of the massage airbag, which can be applied to different usage environments and improve user experience.

Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
