[0038] As shown in Figure 9 and Figure 10 Regarding the composition of the air pump core 1, it includes a shell base 10, a shell cover 11, a motor 12, a piston rod 13, a transmission assembly 14, an air inlet 15, and an impeller 16.

[0039] As shown in Figure 9 and Figures 10 to 12As shown, the shell base 10 has X-axis, Y-axis and Z-axis perpendicular to each other in three-dimensional space, and comprises a base plate 101, a side plate 102, a cylinder pipe 103 and two triangular side plates 104. The side plate 102 is shaped at one end of the base plate 101 in X-axis direction and extends along Z-axis direction. A transmission space 100 is formed between the side plate 102 and the base plate 101. The cylinder pipe 103 is integrally formed outside the side plate 102 and extends along X-axis direction. The cylinder pipe 103 has a cylinder chamber which communicates with the transmission space 100 through the side plate 102. The cylinder pipe 103 has a connecting end 1031 at one end away from the side plate 102. The two triangular side plates 104 are respectively located at both sides of the assembly area in Y-axis direction and extend from the side plate 102 to the other end of the base plate 101 in X-axis direction. The two triangular side plates 104 are respectively located at both sides of the transmission space 100 in Y-axis direction and connect the base plate 101 and the side plate 102, thereby reinforcing the base plate 101 and the side plate 102 of the shell base 10, improving the mechanical strength of the shell base 10, forming a triangular slope type enclosing structure, reducing the amount of material used, and reducing the cost and weight. On the other hand, the cylinder pipe 103 is integrally formed on one side of the side plate 102, which simplifies the structure, improves the assembly convenience, and eliminates the assembly steps of the separated cylinder pipe 103 installed on the side plate 102.

[0040] As shown in Figure 9 , Figures 10 to 12 , the shell cover 11 is detachably installed on the shell base 10. The peripheral edge of the shell cover 11 can tightly contact the edges of the base plate 101, the side plate 102 and the two triangular side plates 104 of the shell base 10. The shell cover 11 and the shell base 10 can be fixed by buckling or screwing. In this embodiment, the shell cover 11 and the shell base 10 are fixed by buckling, which has the function of easy disassembly, and the closed space is formed by tightly covering the opening of the transmission space 100 of the shell base 10 with the shell cover 11.

[0041] As shown in Figure 9 , Figure 10 and Figure 12 , the motor 12 is installed outside the base plate 101 of the shell base 10 and is fixed by screwing or other fixing components. The motor 12 comprises a motor housing, a stator installed in the motor housing and a rotor 122 pivoted in the stator. One end of the rotor 122 passes through the base plate 101 and extends into the transmission space 100. The other end of the rotor 122 can be connected to the impeller 16.

[0042] As shown in Figure 10 , Figures 12 to 14As shown, the side of the motor housing of the motor 12 facing the seat plate portion 101 has one or more heat dissipation holes 123. The seat plate portion 101 of the housing base 10 can further form an abutting protrusion 105 and at least one row of heat dissipation sections 106 on the side of the abutting protrusion 105. The abutting protrusion 105 can abut against the motor housing of the motor 12. The heat dissipation holes 123 correspond to the row of heat dissipation sections 106, so that the hot air generated when the motor 12 operates can be discharged outside through the heat dissipation holes 123 of the motor housing and the corresponding heat dissipation sections 106. In this embodiment, the abutting protrusion 105 is formed as a cross-shaped block with four protrusions. The rotor 122 of the motor 12 is located at the center of the cross-shaped abutting protrusion 105. Each two adjacent protrusions have a heat dissipation section 106 therebetween. This allows the housing base 10 to stably support the motor 12 through the abutting protrusion 105 and facilitates heat dissipation of the motor 12.

[0043] As shown in Figure 10 , Figure 11 and Figure 12 , the piston rod 13 is linearly reciprocally installed in the cylinder tube 103 of the housing base 10 and extends into the transmission space 100. In this embodiment, the piston rod 13 has a rod portion 131 and a piston ring 132. One end of the rod portion 131 is a piston head 1311, and the other end is a pivot joint end 1312. The piston ring 132 is sleeved on the outer circumferential surface of the piston head 1311 and can tightly contact the inner wall of the cylinder tube 103. The pivot joint end 1312 is located in the transmission space 100.

[0044] As shown in Figure 10 , Figure 11 and Figure 12 , the transmission assembly 14 is installed in the transmission space 100 of the housing base 10 and is connected between the piston rod 13 and the rotor 122 of the motor 12, so that the power output by the motor 12 can drive the piston rod 13 to linearly reciprocate in the cylinder tube 103 of the housing base 10 through the transmission assembly 14. In this embodiment, the transmission assembly 14 includes a driving gear 141 and a driven gear 142. The driving gear 141 is connected to one end of the rotor 122 of the motor 12. The driven gear 142 is pivotally installed on the seat plate of the housing base 10 and is engaged with the driving gear 141. The pivot joint end 1312 of the piston rod 13 is eccentrically pivotally installed on the driven gear 142. The driving gear 141 is a pinion gear. The driven gear 142 is a gear larger than the driving gear 141. The driven gear 142 has a hollow portion at the position adjacent to the eccentrically pivotally installed piston rod 13, so as to reduce the material, reduce the weight, and reduce the load of the motor 12.

[0045] As shown in Figure 10 , Figure 11 and Figure 12As shown, the inflation joint 15 is arranged at the connecting end 1031 of the cylinder tube 103 of the housing base 10 and exposed outside the inflation pump housing 2. The inflation joint 15 comprises a joint body 151 and a one-way valve 152 arranged in the joint body 151. The joint body 151 has an inflation end 153 opposite to the other end of the cylinder tube 103. The one-way valve 152 can control the one-way output of the pressurized air in the cylinder tube 103 towards the inflation end 153.

[0046] As shown in Figures 2 to 5 , Figure 7 and Figure 8 , the impeller 16 is arranged in the rectifying area 23 of the inflation pump housing 2. The impeller 16 is located in the vortex space 230 and connected to the other end of the rotor 122 of the motor 12. The impeller 16 can be driven to rotate by the motor 12. Preferably, the impeller 16 is a centrifugal impeller which can intake air axially and discharge air radially. The combination of the impeller 16 and the vortex space 230 can draw the hot air stream from the core assembly chamber 22 of the inflation pump housing 2, pass through the through hole 261 in the partition 26 into the vortex space 230 of the rectifying area 23, and then discharged outside the inflation pump housing 2 through the air outlet.

[0047] As shown in Figures 2 to 5 , Figure 7 and Figure 8 , when the inflation pump is in use, the inflation end 153 of the inflation joint 15 can be connected to an inflation conduit. The inflation conduit has a joint at the end thereof and connected to the object to be inflated such as a tire. The motor 12 of the inflation pump core 1 is started by the switch. The piston rod 13 is driven to reciprocate in the cylinder tube 103 of the housing base 10 by the transmission assembly 14 to generate pressurized air. The pressurized air is input into the object to be inflated through the inflation joint 15 and the inflation conduit. On the other hand, when the motor 12 is started, the impeller 16 is simultaneously driven to rotate. The air stream is introduced into the inflation pump core 1 through the air inlet 24 of the inflation pump housing 2. The air stream absorbs heat from the outer surface of the inflation pump core 1 and then carried from the core assembly area to the vortex space 230 of the rectifying area 23. The hot air stream is rapidly discharged from the air outlet 25 by the vortex generated by the rotating motion of the impeller 16 in the vortex space 230.
