For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0034] like Figures 1 to 11 As shown, this embodiment provides an air pump 01, which includes a pump body 10, an exhaust assembly 20, and a drive assembly 30. The pump body 10 is provided with a crankshaft 11, a connecting rod 12, a piston 13, a cylinder 14, a valve group 15, a sealing gasket 16, a connecting member 17, a shaft bracket 18, and a bearing 19. The piston 13 is provided with a piston body 131 and a piston ring 132. The drive assembly 30 is provided with a motor 31, a frame 32, and a coupling 33. The exhaust assembly 20 and the drive assembly 30 are located at both ends of the pump body 10. The shaft bracket 18 has a regular hexagonal structure. The cylinder 14 is annularly mounted on the shaft bracket 18. The motor 31 drives the crankshaft 11, connecting rod 12, piston 13, and valve group 15 to pump gas through the coupling 33. The gas is collected and pumped out through the exhaust assembly 20. The pump body 10 cooperates with the shaft pin B. 113 and gasket 16 enable multi-stage pump body connection to meet the needs of different pumping flow rates.

[0035] Specifically, the crankshaft 11 is configured as a split structure, consisting of half-shafts 111, pins A 112 and B 113 connected in series. One crankshaft 11 of the pump body 10 is composed of two half-shafts 111 and one pin A 112 connected in series. During assembly, the bearing A 191 is first installed into the main connecting rod 121, and then the half-shafts 111 are inserted into the pins A 112 and installed at both ends of the bearing A 191. The bearing B 192 is disposed in the shaft hole 181. One shaft bracket 18 is disposed at each end of the crankshaft 11, and the outer end of the crankshaft 11 is inserted into the bearing B 192.

[0036] Specifically, the cylinder 14 is circumferentially mounted on the shaft bracket 18. The fixing hole 146 is aligned with the screw hole A 182. The screw A 101 passes through the fixing hole 146 to fix the cylinder 14 on the outer side of the shaft bracket 18. The valve body 151, spring 152, and cover 153 are assembled in the air hole of the cylinder 14. The valve body 151 is located at the innermost part of the air hole 142, and the bottom structure of the air hole 142 is the same as that of the valve body 151. The spring 152 is assembled at the outer end of the valve body 151. The cover 153 presses down on the spring 152. When the spring 152 is compressed, it presses the valve body 151 inward to provide a one-way seal. When the piston 13 is compressed in the cylinder 14, when the internal air pressure of the cylinder 14 is greater than the pressure of the spring 152 on the valve body 151, the gas is discharged from the air hole 142.

[0037] Specifically, one end of the auxiliary connecting rod 122 is hinged to the main connecting rod 121, and the other end is hinged to the piston body 131. The piston ring 132 is fitted onto the piston body 131, and the piston 13 is installed in the air chamber 141. When the crankshaft 11 rotates, it drives the connecting rod 12 to reciprocate. The connecting rod 12 pulls the piston 12 to reciprocate in the air chamber 141 to realize the pumping of fluid.

[0038] Specifically, the air nozzle 21 is connected to the air collecting component 23 via the air pipe 22. The exhaust nozzle 21 is sealed to the connecting nozzle 145 with the sealing gasket 16. The connecting component 17 is sealed to one end of the air passage 143 with the sealing gasket 16 and the connecting groove 144. The exhaust assembly 20 is located at the front end of the pump body 10, and the connecting component 17 is located at the rear end of the pump body 10. The exhaust assembly 20, the pump body 10, and the connecting component 17 are connected by screw B. 24 are connected in series and fixed. When the piston 13 is pulled outward in the cylinder 14, the gas enters the air chamber 141 from the air inlet groove 1321 of the piston ring 132. When the piston 13 is compressed inward in the cylinder 14, the sealing ring 1322 of the piston ring 132 is compressed to prevent the gas from being discharged from the air inlet groove 1321. After being compressed, the gas pushes open the valve body 151 and is pumped out sequentially from the air passage 143, the air nozzle 21, the air pipe 22, and the air collecting component 23.

[0039] Specifically, the motor 31 is fixed to the frame 32 by the screw C 34, and the frame 32 is fixed to the connector 17 by the screw D 35.

[0040] Specifically, the gas 01 is configured with one or more pump bodies 10 by adapting to screws B 24 of different lengths. When multiple pump bodies 10 are stacked, a sealing gasket 16 needs to be configured between the connecting groove 144 and the connecting nozzle 145. The motion connection between the pumps 10 is achieved by inserting the shaft pin B. Stacking multiple pump bodies 10 can achieve a multiplication effect of flow rate.
