In contrast, when the turning pipe 9 is in butt joint with the exhaust hole 18, namely when the air pump discharges air to the inflatable product, the bottom plane of the turning pipe 9 is covered and sealed at the upper port of the supplementing pipe 16, so that air entering the air pumping cavity 13 from the turning pipe 9 can be prevented from directly jumping out of the air pumping cavity 35 through the supplementing pipe 16, and the discharged air in the air pumping cavity 13 can be effectively discharged outwards under the driving of the centrifugal impeller 14, and the air discharging efficiency of the air pump to the inflatable product is ensured.

The following is a control method of the air pump of this embodiment:
when the main air chamber and all the auxiliary air chambers of the inflatable product need to be inflated by using the air pump of the embodiment, the following steps are performed:
S1, opening a main air cavity valve 7 and an auxiliary air cavity valve 8 through a control system 3, starting a fan 2, and simultaneously controlling a bent pipe 9 to move, so that the bent pipe 9 is communicated with an exhaust end of the fan 2, namely, the bent pipe 9 is in butt joint with an inflation hole 17, so that external air is driven to sequentially enter a ventilation cavity 35, an air extraction cavity 13 and an air blowing cavity 12 inside an air pump from an air vent 4, and then respectively enter a main air cavity air supply port 5 and an auxiliary air cavity air supply port 6 through the bent pipe 9.
S2, when the air pressure data monitored by the air pressure sensor rises to a preset first threshold value in the air inflation process, the control system 3 closes each auxiliary air cavity valve 8 to stop the inflation of each auxiliary air cavity of the inflatable product, and meanwhile, the control system 3 keeps the opening state of the main air cavity valve 7 to keep the inflation of the main air cavity of the inflatable product.

And S4, when the air pressure data monitored by the air pressure sensor rises to a preset third threshold value, the control system 3 shuts down the fan 2 and closes each auxiliary air cavity valve 8 so as to stop the inflation of the main air chamber and each auxiliary air chamber of the inflatable product.
It will be understood that in the above-mentioned control method, when the main air chamber and all the auxiliary air chambers of the inflatable product need to be inflated, the main air chamber valve 7 and the auxiliary air chamber valve 8 are opened by the control system 3, the blower 2 is started, and the displacement position of the elbow 9 is controlled to enable the elbow 9 to be communicated with the exhaust end of the blower 2, so as to drive the external air to enter the air pump from the ventilation hole 4 and respectively enter the main air chamber air supply port 5 and each auxiliary air chamber air supply port 6 through the elbow 9, the main air chamber and each auxiliary air chamber of the inflatable product are inflated respectively through the main air chamber air supply port 5 and each auxiliary air chamber air supply port 6, in order to consider the factor that the volume difference between the main air chamber and the auxiliary air chamber of the inflatable product is large, in the control system of the air pump sets a first threshold, a second threshold and a third threshold in advance, and when the air pressure data monitored by the air pressure sensor rises to the preset first threshold in the inflation process, the control system 3 closes each auxiliary air cavity valve 8 and keeps the opening state of the main air cavity valve 7 so as to stop the inflation of each auxiliary air cavity of the inflatable product and keep the inflation of the main air cavity of the inflatable product, namely after each air cavity is inflated to a certain extent and each air cavity of the inflatable product is opened by the input air, the inflation of the auxiliary air cavity with smaller volume is temporarily stopped, the situation that each auxiliary air cavity of the inflatable product is excessively expanded is prevented, meanwhile, the inflation of the main air cavity of the inflatable product is kept, the main air cavity with larger volume is kept to be inflated, when the air pressure data monitored by the air pressure sensor is increased to a preset second threshold value, the main air cavity of the inflatable product is reflected to reach a sufficient inflation state, at the moment, the control system 3 closes the main air cavity valve 7 and opens each auxiliary air cavity valve 8 so as to stop the inflation of the main air cavity of the inflatable product, at this time, the air pump is further enabled to continuously inflate each auxiliary air chamber which is not fully inflated, so that the situation of over inflation of the auxiliary air chamber of the inflatable product can be prevented, and finally when the air pressure data monitored by the air pressure sensor rises to a preset third threshold value, the control system 3 shuts down the fan 2 and closes each auxiliary air chamber valve 8 so as to stop inflation of the main air chamber and each auxiliary air chamber of the inflatable product, and each air chamber of the inflatable product is kept in an inflated state, so that normal use can be put into use.
Further, when the air pump of the present embodiment is required to deflate the main air chamber and all the sub air chambers of the inflatable product, the following steps are performed:
S1, opening a main air cavity valve 7 and an auxiliary air cavity valve 8 through a control system 3, starting a fan 2, simultaneously switching the displacement position of a bent pipe 9, enabling the bent pipe 9 to be communicated with an air exhaust end of the fan 2, namely enabling the bent pipe 9 to be in butt joint with an exhaust hole 18 so as to drive air of a main air chamber and each auxiliary air chamber of an inflatable product to enter the bent pipe 9 from a main air cavity air supply port 5 and each auxiliary air cavity air supply port 6 and sequentially enter an air exhaust cavity 13, an air blowing cavity 12 and an air exchanging cavity 35 in an air pump, and finally exhausting outwards through an air exchanging hole 4 of the air pump;
S2, when the air pressure data monitored by the air pressure sensor is reduced to a preset fourth threshold value, the control system 3 is used for closing the main air cavity valve 7 and the auxiliary air cavity valve 8 and stopping the fan 2.
So that all the air chambers of the inflatable product can be deflated by the method.
Further, when the air pressure of the main air chamber or the auxiliary air chamber of the inflated product needs to be continuously adjusted after inflation is completed, the following steps are executed:
Starting the fan 2 through the control system 3 and switching the displacement position of the turning pipe 9, enabling the turning pipe 9 to be communicated with the exhaust end of the fan 2, namely enabling the turning pipe 9 to be in butt joint with the inflation hole 17, opening the main air cavity valve 7 or the auxiliary air cavity valve 8, driving external air to enter the main air cavity air supply port 5 or the auxiliary air cavity air supply port 6 through the turning pipe 9 by using the fan 2 so as to inflate a main air chamber or an auxiliary air chamber of an inflated product;
When the air pressure of the main air chamber or the auxiliary air chamber of the inflatable product needs to be regulated and reduced after the inflation is completed, the following steps are executed;
The main air cavity valve 7 or the auxiliary air cavity valve 8 is opened through the control system 3, so that the air of the main air cavity or the auxiliary air cavity of the inflatable product enters the air pump through the bent pipe 9 and is naturally discharged outwards through the ventilation hole 4, and at the moment, the fan 2 is not required to be started, so that the air conditioner is more energy-saving and environment-friendly.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present utility model, but not for limiting the same, and simple modifications or equivalent substitutions for the technical features of the present embodiment are all within the protection scope of the present utility model.
