What is claimed is: 
     
         1 . The present disclosure provides an air pump device, comprising a housing; a high-pressure air pump, a low-pressure air pump and a public pipeline are arranged in the shell; the high-pressure air pump is a reciprocating air pump, and comprises a motor, a piston tube and a piston; the piston is arranged in the piston tube; the motor is used for driving the piston to move in the piston tube; an output shaft of the motor is perpendicular to an axial direction of the piston tube; an air outlet end of the piston tube is connected with the public pipeline, and the piston tube and the public pipeline are parallel or located on the same straight line; the low-pressure air pump is a blowing-type air pump, and comprises a shell and a fan assembly; one end of the low-pressure air pump is connected to a side wall of the public pipeline; and the low-pressure air pump and the motor are parallel to each other and are located on the same side of the public pipeline. 
     
     
         2 . The air pump device according to  claim 1 , wherein the air pump device comprises a high-pressure mode and a low-pressure mode; the air pump device is provided with an air pressure sensor; in the low-pressure mode, the high-pressure air pump does not work, and the low-pressure air pump works and inflates the public pipeline; in the high-pressure mode, the air pressure sensor monitors an air pressure in the public pipeline; the low-pressure air pump first works and inflates the public pipeline; when the air pressure sensor monitors that an air pressure value is greater than a preset pressure value, the low-pressure air pump stops working, and the high-pressure air pump is started to work; and the preset pressure value is M times a maximum air pressure value that is achieved by the low-pressure air pump, and M is less than 1. 
     
     
         3 . The air pump device according to  claim 2 , wherein the M is between 0.6 and 0.8, and the maximum air pressure value that is achieved by the low-pressure air pump is 1 PSI. 
     
     
         4 . The air pump device according to  claim 3 , wherein the M is 0.7. 
     
     
         5 . The air pump device according to  claim 2 , wherein the air pump device comprises an air pumping mode; and in the air pumping mode, the high-pressure air pump does not work, and the low-pressure air pump reversely pumps the air out of the public pipeline. 
     
     
         6 . The air pump device according to  claim 1 , wherein the air pump device comprises a control board and buttons connected with the control board and arranged at a position corresponding to the shell. 
     
     
         7 . The air pump device according to  claim 1 , wherein one end of the public pipeline opposite to the high-pressure air pump extends to the housing to form a first air port; the other end of the low-pressure air pump extends to the housing to form a second air port; and the first air port and the second air port are externally connected with a pipeline. 
     
     
         8 . The air pump device according to  claim 1 , further comprising a circuit board, wherein the circuit board is arranged in the housing; a display screen and functional buttons are arranged on the housing; and the display screen and the functional buttons are connected with the circuit board.
