Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The invention provides an exhaust control method of air pressure massage equipment and the air pressure massage equipment, and the main technical scheme comprises the following steps: when the air pressure massage equipment needs to be exhausted, detecting the air pressure in the air bag of the air pressure massage equipment in real time; and adopting a corresponding exhaust mode for exhausting according to the gas pressure, wherein the exhaust mode comprises the following steps: the air-pressure massage device comprises an air discharging mode and an air extracting mode, wherein in the air discharging mode, the air-pressure massage device discharges air through an air discharging electromagnetic valve, and in the air extracting mode, the air-pressure massage device extracts air through an air pump.
It can be understood that when the air pressure massage equipment exhausts with the mode of exitting, when deflating naturally through the air-out solenoid valve promptly, because the gas in the gasbag is reducing gradually, can make gasbag atmospheric pressure reduce, and the gasbag also can reduce with atmospheric pressure difference, and then makes exhaust efficiency diminish gradually, when just beginning to deflate promptly, exhaust efficiency is the biggest, along with the continuation of gassing process, exhaust efficiency diminishes gradually. When the air pressure massage equipment exhausts in an air exhaust mode, namely air is exhausted through the air pump, the exhaust efficiency is always kept fixed. In practical applications, the deflation mode has a higher deflation efficiency than the deflation mode when the balloon gas pressure is higher, and the deflation mode has a higher deflation efficiency than the deflation mode when the balloon gas pressure is lower. If the air discharge is performed only in the deflation mode, the air discharge efficiency is lower compared to the deflation mode when the air pressure in the airbag becomes small, and if the air discharge is performed only in the deflation mode, the air discharge efficiency is lower compared to the deflation mode when the air pressure in the airbag is large, and the air pump needs to be always turned on. Based on the air pressure, the air pressure in the air bag is determined by detecting the air pressure in the pipeline of the air pressure massage equipment in real time, and the corresponding air exhaust mode is flexibly selected according to the air pressure, namely when the air pressure is higher, the air pressure massage equipment is controlled to exhaust in the air exhaust mode, when the air pressure is lower, the air pressure massage equipment is controlled to exhaust in the air exhaust mode, so that the air exhaust efficiency of the air pressure massage equipment is improved, an air pump does not need to be opened all the time, and the electric consumption of the air pressure massage equipment is reduced.

Based on the pneumatic massage device, the exhaust control method of the pneumatic massage device according to the embodiment, as shown in fig. 2, includes the following steps:
step 201, detecting the gas pressure in an air bag of the air pressure massage equipment in real time when the air pressure massage equipment needs to be exhausted;
specifically, the device host computer passes through the pressure detection module and acquires the gas pressure in the atmospheric pressure massage device pipeline in real time, owing to before atmospheric pressure massage device exhausts, need open the solenoid valve that each gasbag corresponds, can make the gas pressure on trunk line, the branch pipeline equal with the gas pressure of each gasbag. The embodiment detects the gas pressure in the air bag by arranging the pressure detection module on the main pipeline, but is not limited to the main pipeline, and the pressure detection module can also be arranged on the branch pipeline or the air bag, and can also realize accurate detection of the gas pressure in the air bag.
And step 202, adopting a corresponding exhaust mode to perform exhaust according to the gas pressure.
As shown in fig. 3, in the present embodiment, when the gas pressure in the air bag is greater than the critical gas pressure value, the pneumatic massage device is controlled to perform air discharge in the deflation mode; when the air pressure in the air bag is smaller than or equal to the critical air pressure value, the air pressure massage equipment is controlled to exhaust air in an air exhaust mode.
In practical application, if the air pressure massage device needs to be exhausted, because the air pressure in the air bag is larger and usually larger than the critical air pressure value when the air is just exhausted, the efficiency of exhausting by adopting the air-bleeding mode is larger than the efficiency of exhausting by adopting the air-bleeding mode, so that the air pressure massage device can be controlled to exhaust in the air-bleeding mode, and the specific control method comprises the following steps: the equipment host machine closes the air pump, controls the coil of the first three-way electromagnetic valve not to be electrified, controls the coil of the second three-way electromagnetic valve to be electrified, and opens the air discharge electromagnetic valve and the electromagnetic valves A-E.
As shown in fig. 4, when the coil of the first three-way solenoid valve is not energized, the first port is communicated with the second port, and the third port is closed, and when the coil of the second three-way solenoid valve is energized, the first port is communicated with the third port, and the second port is closed. At the moment, the air pump and the right side are completely separated by the first three-way electromagnet and the second three-way electromagnet, the air bleeding process is not interfered, the air pressure massage equipment exhausts in a bleeding mode, namely, the air is bled through the bleeding electromagnetic valve, and the air flow at the moment is as follows: air bag A-E → electromagnetic valve A-E → air bleed electromagnetic valve → atmosphere.
The gas pressure in the air bag is gradually reduced along with the continuation of the exhaust process, when the gas pressure is smaller than or equal to the critical pressure value, the gas pressure in the air bag is smaller, and when the gas pressure is in the critical pressure state, the exhaust efficiency is the same by adopting the air discharge mode and the air exhaust mode. When the gas pressure in the air bag is smaller than the critical pressure value, if the deflation mode is adopted for deflation, the exhaust speed is rapidly reduced and residual gas in the air bag cannot be exhausted, in order to solve the problems, the implementation controls the air pressure massage equipment to exhaust in the air exhaust mode at the moment, and the specific control method is as follows: the equipment host closes the air discharge electromagnetic valve, controls the coil of the first three-way electromagnetic valve and the coil of the second three-way electromagnetic valve to be electrified, and opens the air pump and the electromagnetic valves A-E. The critical air pressure value is selected as the connection point of the air discharge mode and the air suction mode, so that the whole air discharge process is smooth, the pause and the contusion cannot be generated in the air discharge process, and the whole air discharge process can be smoothly finished.
As shown in fig. 5, when the coil of the first three-way solenoid valve is energized, the first port thereof communicates with the third port, and the second port is closed, and when the coil of the second three-way solenoid valve is energized, the first port thereof communicates with the third port, and the second port is closed. At the moment, the air pressure massage equipment exhausts in an air exhaust mode, namely, the air pump is used as an air power source, and residual air in the air bag is completely exhausted through reversing of the two three-way electromagnetic valves. The air flow direction is as follows: the air bag a-E → the solenoid valve a-E → the third port of the first three-way solenoid valve → the first port of the first three-way solenoid valve → the air intake passage of the air pump → the air outlet passage of the air pump → the first port of the second three-way solenoid valve → the third port of the second three-way solenoid valve → the atmosphere.
Through the scheme, when the air pressure is greater than the critical air pressure value, the air pressure massage equipment is controlled to exhaust in the air discharging mode, when the air pressure is less than or equal to the critical air pressure value, the air pressure massage equipment is controlled to exhaust in the air exhausting mode, the air discharging efficiency of the air pressure massage equipment is further improved, an air pump does not need to be opened all the time, and the electric quantity consumption of the air pressure massage equipment is also reduced.
The pneumatic massage equipment described in this embodiment can still control the air pump to inflate the air bag, and the specific control method is as follows: the equipment host closes the air discharge electromagnetic valve, controls the coil of the first three-way electromagnetic valve and the coil of the second three-way electromagnetic valve not to be electrified, and opens the air pump and the electromagnetic valve corresponding to the airbag to be inflated.
As shown in fig. 6, when the coil of the first three-way solenoid valve is not energized, the first port communicates with the second port, and the third port is closed, and when the coil of the second three-way solenoid valve is not energized, the first port communicates with the second port, and the third port is closed. The air flow direction at this time is: atmospheric air → the second port of the first three-way solenoid valve → the first port of the first three-way solenoid valve → the air intake passage of the air pump → the air outlet passage of the air pump → the first port of the second three-way solenoid valve → the second port of the second three-way solenoid valve → the solenoid valves a-E → the airbags a-E.
Through the above-mentioned scheme of this embodiment, not only can improve the exhaust efficiency of atmospheric pressure massage equipment and reduce the electric quantity consumption of atmospheric pressure massage equipment, can also realize simultaneously aerifing and gassing through an air pump, realized filling the accurate control of gassing to the gasbag to compare with the design of the gassing of filling respectively of current two air pumps, the cost is reduced.
In this embodiment, a critical air pressure value may be set in the device host in advance, and the critical air pressure value may be determined by human experience, or may be determined by the air flow aperture when the deflation solenoid valve, the three-way solenoid valve, and the solenoid valves corresponding to the respective air bags are opened, the volume of the air bags, the change in the air pressure in the air bags, the working parameters of the air pump, and the like.
As described above, since the discharge efficiency of the deflation mode is greater than that of the deflation mode when the gas pressure inside the airbag is large, the discharge efficiency of the deflation mode is greater than that of the deflation mode when the gas pressure inside the airbag is small. In order to accurately determine the critical air pressure value of the air pressure, that is, the air pressure when the air discharge efficiency of the air discharge mode is equal to the air discharge efficiency of the air suction mode, and further improve the air discharge efficiency of the air pressure massage apparatus, as shown in fig. 7, the method for obtaining the critical air pressure value according to this embodiment further includes:
step 701, determining the air exhaust flow of the air pressure massage equipment in an air exhaust mode;
as shown in fig. 8, in this embodiment, a gas flow meter may be connected to the third port of the second three-way electromagnetic valve, and then the pneumatic massage device is controlled to be in the air-extracting mode, and the air-extracting flow rate is determined by measuring through the gas flow meter when the pneumatic massage device is in the air-extracting mode. Because the air exhaust flow is basically unchanged in the air exhaust mode, the air exhaust flow can be directly measured. In practical application, in order to improve the accuracy of the air extraction flow, the average value can be obtained after multiple measurements.
And 702, detecting the discharge flow of the air pressure massage equipment in the air discharge mode in real time, acquiring the current air pressure in the pipeline of the air pressure massage equipment when the discharge flow is equal to the air discharge flow, and taking the current air pressure as a critical air pressure value.
As shown in fig. 9, this embodiment may connect a gas flow meter to the air discharge end of the air discharge solenoid valve, then control the air pressure massage device to be in the air discharge mode, and determine the discharge flow through the measurement of the gas flow meter when the air pressure massage device is in the air discharge mode. Since the discharge flow at the beginning of the discharge is the largest in the discharge mode, the discharge flow gradually decreases as the gas pressure in the airbag decreases, when the discharge flow is equal to the bleed flow, the current gas pressure is determined by the pressure detection module, and the current gas pressure is taken as the critical gas pressure value.
It can be understood that the critical air pressure value in the present embodiment indicates that the discharge flow rate is equal to the air suction flow rate, that is, when the air pressure massage device performs air suction, if the air pressure in the air bag is greater than the critical air pressure value, the air discharge efficiency in the air suction mode is greater than the air discharge efficiency in the air suction mode, and if the air pressure in the air bag is less than the critical air pressure value, the air discharge efficiency in the air suction mode is greater than the air discharge efficiency in the air suction mode. According to the embodiment, the critical air pressure value is conveniently and accurately determined through the scheme, the air pressure massage equipment is controlled to exhaust in the air exhaust mode when the air pressure is larger than the critical air pressure value, and the air pressure massage equipment is controlled to exhaust in the air exhaust mode when the air pressure is equal to or smaller than the critical air pressure value, so that the exhaust efficiency of the air pressure massage equipment is further improved.
In this embodiment, in order to reduce the links of the product in the production process, the critical air pressure value may be measured in the research and development stage, and the measured critical air pressure value is directly written into the product embedded program in the device host, and then the measurement of the critical air pressure value is not needed for mass production of the product.
Further, as shown in fig. 2, the present embodiment further includes the following steps:
and 203, closing the air pressure massage equipment when the air pressure is negative.
As shown in fig. 3, when the air pressure in the air bag is negative, it indicates that there is no air in the air bag, and the purpose of releasing all air in the air bag is completely achieved, and at this time, the air pressure massage device is turned off, so that the air bag is automatically turned off after the air exhaust is completed, further the air bag is prevented from being damaged by continuous air exhaust when there is no air in the air bag, and meanwhile, the power consumption of the air pressure massage device can be reduced.
In summary, according to the exhaust control method of the air pressure massage device and the air pressure massage device provided by this embodiment, the air pressure in the air bag is determined by detecting the air pressure in the pipeline of the air pressure massage device in real time, and the corresponding exhaust mode is flexibly selected according to the air pressure, that is, when the air pressure is greater than the critical air pressure value, the exhaust efficiency of the exhaust mode is greater than that of the exhaust mode, and at this time, the air pressure massage device is controlled to exhaust in the exhaust mode, and when the air pressure is less than the critical air pressure value, the exhaust efficiency of the exhaust mode is greater than that of the exhaust mode, and at this time, the air pressure massage device is controlled to exhaust in the exhaust mode, so that the exhaust efficiency of the air pressure massage device is improved, and the air pump does not need to be opened all the time, thereby reducing the power consumption of the air pressure massage device.
