In actual operation, when the air pressure regulator is required to perform air pressure regulation on the air bag 1, a preset pressure value is set according to user preference or pre-stored data on the control board 3. In the initial state, the actual pressure value C2 in the air bag 1 is the same as the external atmospheric pressure and is far smaller than the preset pressure value C1, so that the parameter delta C is obtained, the parameter delta C changes along with the pressure change of the air bag 1, the precise control air pump 6 controls the start and stop according to the preset parameter A1 and the parameter A2, the quick air pump 5 controls the close through the preset parameter B, and the air bag 1 is rapidly and precisely inflated through the quick air pump 5 and the precise control air pump 6.
When the actual pressure value of the airbag 1 is greater than the preset pressure value due to the over-inflation or the thermal expansion of the original air, the controller controls the actual pressure value to decrease and approach the preset pressure value by opening the exhaust valve 10 to exhaust the air.
In actual operation, different operation modes are obtained by adjusting the relation among the parameters A1, A2 and B, so that the inflation and deflation assembly has different characteristics when the air bag 1 is inflated. When the air bag 1 needs to be inflated, the control panel 3 controls the quick inflator 5 to be automatically started, and controls the quick inflator 5 to be stopped according to the size relation between C2 and B. When the air bag 1 needs to be inflated, the control board 3 controls the accurate control air pump 6 to be started according to the size relation between A1 and C2, and controls the accurate control air pump 6 to be stopped according to whether C2 falls into the allowable deviation range of C1.
Mode one:
In this mode, a1=b, and the inflation and deflation assembly goes through the fast inflation pump 5 alone operation state, the fine control air pump 6 alone operation state, and the double air pump stop state in order as the parameter C2 rises. When C2 is less than a1=b, the quick inflator 5 works alone to quickly inflate the airbag 1; when c2=a1=b, the fast inflator 5 and the precision control air pump 6 are both in a stop state; when C2 > a1=b, the precisely controlled air pump 6 is operated alone until C2 falls within the allowable deviation range of C1.

In this mode, A1 < B, the inflation and deflation assembly goes through the fast inflation pump 5 alone operation state, the double air pump operation state, the precise control air pump 6 alone operation state and the double air pump stop state in sequence along with the rising of the parameter C2. When C2 is more than A1 and less than B, the quick inflator pump 5 works independently to quickly inflate the air bag 1; when A1 is less than or equal to C2 and less than B, the precise control air pump 6 and the quick air pump 5 run simultaneously, play a role in the running connection of the precise control air pump and the quick air pump, and prevent the two from stopping simultaneously; when A1 is more than B and less than or equal to C2, the quick air pump 5 is stopped, and the precise control air pump 6 works independently until C2 falls within the allowable deviation range of C1. Under this kind of mode, the condition that does not have two air pumps to shut down simultaneously in the whole inflation process, the fine control air pump 6 can be through running in advance come with be in the fast pump 5 of running state match the linking, and then improve inflation efficiency, shorten the inflation time.
Mode three:
In this mode, the precisely controlled start pressure threshold A1 is smaller than the initial pressure of the air bag 1, and the inflation and deflation assembly sequentially goes through a dual air pump operation state, a separately operated state of the precisely controlled air pump 6, and a dual air pump stop state as the parameter C2 rises. In the process, the precise control air pump 6 participates in the whole air charging process, and when C2 is less than B, the precise control air pump 6 and the quick air charging pump 5 are synchronously started to run, so that the maximum air charging speed is obtained, and the time of quick air charging is further shortened; when C2 is more than or equal to B, the quick inflator pump 5 is stopped, the precise control air pump 6 continues to work, and the air pressure of the air bag 1 is precisely adjusted until C2 falls into the allowable deviation range of C1. In this mode, the air cushion bed has the shortest inflation time, effectively improving the use experience.
The user can select different modes according to the needs to meet the use requirements of people with differentiation.
In actual operation, the parameter C1 has an allowable deviation range of ±2%, and when the Δc > 0 condition is triggered, the parameter C1 is a lower limit value of the allowable deviation range, and when the Δc <0 condition is triggered, the parameter C1 is an upper limit value of the allowable deviation range. The sensitivity requirements on the air pressure sensing piece 11 and the precise control air pump 6 are reduced by setting the allowable deviation range, the air pressure adjusting time of the air bag 1 is effectively shortened, and the production cost and the debugging difficulty are also reduced. The range of the allowable deviation range can be adjusted according to actual conditions, and the allowable deviation range is considered as a specific embodiment of the invention.
In actual operation, A1 is less than 2% C1. The adjusting precision value of the precise control air pump 6 is smaller than the allowable deviation range of the parameter C1, so that the air pressure of the air bag 1 can be ensured to be adjusted to be within the allowable deviation range of the parameter C1 through the precise control air pump 6, and the condition that the air pressure of the air bag 1 is over-pressure or under-pressure due to poor adjusting precision of the precise control air pump 6 is prevented.
In actual operation, the parameter C1 is adjusted according to the actual requirement of the user or the pre-stored data in the control board 3. When the parameter C1 changes, the quick inflation and shutdown pressure threshold B of the quick inflator pump 5 also changes, so that a precise control interval for the precise control air pump 6 to work independently is formed between the parameter C1 and the parameter B, when the precise control interval has a proper range, the air bag 1 is ensured to approach to a preset pressure value as much as possible under the action of the quick inflator pump 5, the air bag 1 can be ensured to be regulated to the preset pressure value as soon as possible, and the situation that the quick inflator pump 5 is over-pressurized due to delay shutdown is effectively prevented, so that the use experience is affected. Specifically, when the absolute value of the parameter C1 is smaller, the precise control interval should be larger, so as to prevent the air bag 1 from having an over-inflation condition, and when the absolute value of the parameter C1 is larger, the precise control interval should be smaller, so as to ensure that the air pressure of the air bag 1 can be rapidly raised to a preset pressure value by the quick inflator 5.
When C1 is less than or equal to 20KPA, C1-B is less than or equal to 10KPA and less than or equal to 20KPA, and because the preset pressure value is lower, when C1-B is more than C1, the quick inflator pump 5 can be in a stop state in the whole inflation process, the air bag 1 is prevented from being in an overpressure condition under the action of the quick inflator pump 5, and the precise control air pump 6 can complete the inflation work of the air bag 1 through independent operation.
When 20KPA < C1.ltoreq.30 KPA, the preferred embodiment is C1-B=10 KPA. For example, when c1=25 KPA, the quick inflator 5 assists the air pressure of the air bag 1 to be raised to 15KPA, and then the air pressure of the air bag 1 is raised to 25KPA by the accurate control air pump 6 through a single operation mode. In addition, the value of C1-B may be adjusted as desired, for example, 7KPA, 9KPA, 11KPA, 15KPA, etc., as long as the requirements of 7 KPA.ltoreq.C1-B.ltoreq.15 KPA are met.
When 30KPA < C1.ltoreq.50 KPA, the preferred embodiment is C1-B=5 KPA. For example, when c1=45 KPA, the quick inflator 5 assists the air pressure of the air bag 1 to be raised to 40KPA, and then the air pressure of the air bag 1 is raised to 45KPA by the accurate control air pump 6 through a single operation mode. In addition, the value of C1-B may be adjusted as desired, for example, 3KPA, 4KPA, 6KPA, 7KPA, etc., as long as the requirements of 3 KPA.ltoreq.C1-B.ltoreq.7 KPA are met.
