Among them, the first air inlet 104 and the first air outlet 103 are on the low-pressure pump shell 11, and the second air inlet 105 and the second air outlet are on the high-pressure pump shell 12.

[0055] The pump cavity 10 comprises an upper cavity 101 above the plug 3 and a lower cavity 102 below the plug 3. Specifically, the plug 3 is movably arranged in the third high-pressure pump shell 12C, and the plug 3 and the first high-pressure pump shell 12A, the second high-pressure pump shell 12B, and the third high-pressure pump shell 12C enclose the lower cavity 102, and the plug 3 and the first low-pressure pump shell 11A and the second low-pressure pump shell 11B enclose the upper cavity 101.

[0056] As shown in Figure 3 and Figures 5-6 , the air extraction mechanism 2 is installed on the pump body 1 and can deliver air to the first air outlet 103 or the second air outlet. Specifically, the first air extraction mechanism 2A comprises an impeller 22 and a first motor 21 for driving the impeller 22, and further comprises a first one-way valve 25, wherein the impeller 22 is arranged in the pump cavity 10, and the first motor 21 is arranged on the pump body 1. The first motor 21 rotates to drive the impeller 22 to rotate, and the impeller 22 sucks air from the first air inlet 104 and delivers the air to the first air outlet 103 through the first one-way valve 25. The first one-way valve 25 is arranged to prevent air from moving from the first air outlet 103 to the first air inlet 104.

[0057] The second air extraction mechanism 2B comprises a compression piston 24 and a second motor 23 for driving the compression piston 24 to swing, and further comprises a driving gear 231, a driven gear 232, and a second one-way valve 26, wherein the compression piston 24 is arranged in the pump cavity 10 to compress air, the second motor 23 is arranged on the pump body 1, a driving gear 231 is arranged on the rotating shaft of the second motor 23, a driven gear 232 is arranged in the lower cavity 102, the driven gear 232 is engaged with the driving gear 231, and the driven gear 232 is connected to one end of the compression piston 24, and the connection is offset from the center of the driven gear 232. The second motor 23 rotates to drive the driving gear 231 to rotate, which in turn drives the driven gear 232 to rotate, and then drives the compression piston 24 to swing to compress air. The second one-way valve 26 is arranged to ensure that the air flow in the lower cavity 102 can only be transmitted from bottom to top, but not from top to bottom. The second one-way valve 26 comprises a plurality of valve cores and a plurality of springs, and when the air pressure value of the compressed air compressed by the compression piston 24 reaches a certain size, the springs can be compressed, and the compressed air can be transmitted from bottom to top.

[0058] As shown in Figure 3 and Figures 7-9 , the plug 3 is movably arranged at the second air outlet, and the plug 3 has a first position (as shown in Figure 8 and a second position (as shown in Figure 9The plug 3 can be switched between the first position and the second position, when the plug 3 is in the first position, the plug 3 blocks the second gas outlet, at this time, the air pump cannot output gas from the second gas outlet, that is, the high-pressure air inlet cannot work when the air outlet connector 4 is not connected, which ensures the safety performance of the air pump and prevents the air pump from outputting high-pressure gas to inflate the air mattress or paddle products. During use, when the air outlet connector 4 is installed on the second gas outlet, the air outlet connector 4 drives the plug 3 to switch to the second position, and the gas of the air pump can be output from the air outlet connector 4. When the air outlet connector 4 is detached from the second gas outlet, the plug 3 switches to the first position.

[0059] Specifically, the gas outlet cross-sectional area of the air outlet connector 4 is much smaller than the gas outlet cross-sectional area of the first gas outlet 103, the gas outlet cross-sectional area of the first gas outlet 103 is larger, which is suitable for large flow and low pressure gas output, and can be applied to the inflation of paddle or air mattress products; the gas outlet cross-sectional area of the second gas outlet is smaller, which is suitable for small flow and high pressure gas output, and can be applied to the inflation of automobile tire products. One end of the air outlet connector 4 is provided with external threads 40, and the second gas outlet is provided with internal threads, the air outlet connector 4 and the second gas outlet can be connected by the external threads 40 and the internal threads. Since the second gas outlet is provided on the threaded connector in the pump body 1, that is, the air outlet connector 4 and the threaded connector can be detachably connected by threads, which is convenient for disassembly and assembly. The connection between the third high-pressure pump shell 12C and the threaded connector is also threaded connection, which is convenient for disassembly and assembly between the threaded connector and the third high-pressure pump shell 12C.

[0060] In Figures 7-9 In order to ensure that the plug 3 can move left and right in the pump cavity 10, the end of the plug 3 away from the air outlet connector 4 is provided with a tension spring 300, and the tension spring 300 abuts against the air outlet connector 4. When the air outlet connector 4 drives the plug 3 to switch from the first position to the second position, the plug 3 compresses the tension spring 300. When the air outlet connector 4 is detached from the second gas outlet, the tension spring 300 switches the plug 3 from the second position to the first position, that is, the tension spring 300 can drive the plug 3 to reset from the second position to the first position.

[0061] Further specifically, the third high-pressure pump body 1 is respectively provided with a detachable threaded joint and a detachable threaded screw cap, and the second gas outlet is arranged on the threaded joint. The threaded joint is close to one end of the plug 3, the threaded screw cap is close to the other end of the plug 3, and the tension spring 300 abuts against the threaded screw cap away from one end of the plug 3. When the threaded joint or the threaded screw cap is removed, the plug 3 can be removed from the pump body 1, that is, when the plug 3 or the tension spring 300 needs to be removed and replaced, the threaded joint or the threaded screw cap can be removed from the third high-pressure pump body 1, and then the plug 3 can be pulled out. A plurality of sealing rings are arranged along the axial direction of the plug 3 to prevent air leakage. In actual use, since the plug 3 needs to be moved left and right repeatedly, the plug 3 is prone to wear after being used for a long time. The threaded joint and the threaded screw cap are arranged to facilitate replacement of the plug 3.

[0062] When the gas outlet joint 4 is threadedly connected to the threaded joint, the plug 3 needs to guide the gas, so in the embodiment, the plug 3 is provided with a gas flow channel 30. When the plug 3 is in the first position, the gas flow channel 30 is in communication with the pump cavity 10, and the gas in the air pump can be sequentially discharged from the pump cavity 10 through the gas flow channel 30 and the gas outlet joint 4.

[0063] Specifically, as shown in Figure 8 The plug 3 is provided with a first annular groove 31 along the circumference thereof, and the plug 3 is provided with a second annular groove 32 along the circumference thereof, and the second annular groove 32 is arranged side by side with the first annular groove 31, and the gas flow channel 30 is in communication with the second annular groove 32. When the plug 3 is in the first position, the first annular groove 31 is in communication with the upper cavity 101 and the lower cavity 102. Among them, two first through holes 120 arranged in an upper and lower manner are respectively arranged on the third high-pressure pump shell 12C, and when the plug 3 is in the first position, the annular groove is in communication with the upper and lower two first through holes 120, so that the upper cavity 101 and the lower cavity 102 are in communication with each other. At this time, the first air suction mechanism 2A can suck air from the first air inlet 104, output the air from the first air outlet 103 after passing through the first one-way valve 25; the second air suction mechanism 2B can suck air from the second air inlet 105, output the air from the first air outlet 103 after passing through the second one-way valve 26 and the plug 3; and at this time, the second air outlet is not connected to the gas outlet joint 4, so the second air outlet is in a state of being blocked by the plug 3 and cannot output high-pressure gas.

[0064] As shown in Figure 9As shown, a second through hole 121 is arranged on the lower side of the third high-pressure pump shell 12C, and the second through hole 121 is on the side of the lower cavity 102. When the plug 3 is in the second position, the second annular groove 32 is in communication with the lower cavity 102. The first annular groove 31 and the second annular groove 32 also move to the right as the plug 3 moves to the right. When the plug 3 is in the second position, the first annular groove 31 is no longer in communication with the first through hole 120 on the upper and lower sides of the third high-pressure pump shell 12C, and the second annular groove 32 is in communication with the second through hole 121, so that the lower cavity 102, the second through hole 121, the second annular groove 32, the air flow passage 30, and the air outlet connector 4 are sequentially in communication, and the air compressed by the second air suction mechanism 2B can enter from the second air inlet 105 and be output from the air outlet connector 4, which is suitable for outputting high-pressure gas from the air outlet connector 4 at this time.

[0065] In actual use, when the air outlet connector 4 is not installed on the second air outlet, the plug 3 blocks the second air outlet (the plug 3 is in the first position), and at this time the air pump cannot output gas from the second air outlet, and the air pump can only output gas from the first air outlet 103, and both the first air suction mechanism 2A and the second air suction mechanism 2B can deliver gas to the first air outlet 103. At this time, the air pump is in an air outlet mode with low air pressure and large air flow, which is suitable for inflating products such as paddle boards and air bed. When the air outlet connector 4 is installed on the second air outlet, the air outlet connector 4 is threadedly connected to the second air outlet, and the air outlet connector 4 presses the plug 3 inward to drive the plug 3 to switch from the first position to the second position, that is, the lower cavity 102, the air flow passage 30 on the plug 3, and the air outlet connector 4 are sequentially in communication at this time, and the air pump at this time can output high-pressure gas from the air outlet connector 4 on the second air outlet, and at this time the second air suction mechanism 2B delivers gas to the second air outlet. The air outlet cross-sectional area of the air outlet connector 4 is small, and at this time the air pump is in an air outlet mode with high air pressure and small flow, which is suitable for inflating products such as tires. That is, the air pump of the present embodiment can only output high-pressure gas from the second air outlet when the air outlet connector is threadedly connected to the second air outlet, which can effectively prevent the air pressure output port from being connected incorrectly, can effectively prevent the product from being inflated, has high safety performance, and is easy to use.

[0066] In addition, in the present scheme, the high-pressure inflation module and the low-pressure inflation module are modularly arranged, and can be used separately after being removed, and when a single function is damaged, the other function can still be used, and replacement and maintenance are convenient.
