[0033] In the process of inflating the bicycle, the inflation assembly is connected with the bicycle tire inflation nozzle, gas is generated by drive structure 20 and inflator assembly 30, the generated gas is delivered to the inside of the inflation assembly through one-way valve 50 and connecting barrel 51, so as to inflate the bicycle tire, and the pressure during inflation can be measured by pressure sensor 60, the operator can understand the pressure during inflation by observing digital display screen 40, because one-way valve 50 is connected with the bicycle tire inflation nozzle through connecting barrel 51 and inflation assembly, the pressure measured by pressure sensor 60 at this time can be regarded as the pressure of the bicycle tire, and the effective timing of disconnecting the inflation process can be determined by the pressure inside the bicycle tire.

[0034] Drive structure 20, inflator assembly 30, digital display screen 40 and one-way valve 50 are integrated and installed in the inside of the main machine 10, so that the bicycle electric inflator pump has a small volume, and the inflation assembly is detachable, so that the bicycle electric inflator pump is convenient to carry, and the bicycle electric inflator pump also has the advantages of small vibration, low noise, short inflation time, high inflation efficiency, etc.

[0035] It should be noted that digital display screen 40 has the functions of displaying tire pressure, power reminder, and charging progress bar display lamp.

[0036] As Figure 3 and Figure 4 , inflator assembly 30 includes a fixed support 31 installed in the inside of the main machine 10, a cylinder 32 connected with one-way valve 50 is fixedly installed on the fixed support 31, a piston 33 is slidably connected in the inside of the cylinder 32, a transmission rod 34 is connected with the piston 33, the length direction of the transmission rod 34 is parallel to the length direction of the main machine 10, a transmission bearing 35 is fixedly connected to the end of the transmission rod 34 away from the piston 33, and the transmission bearing 35 is connected with drive structure 20.

[0037] The driving structure 20 comprises a brushless motor 21 mounted on a fixed support 31, the output direction of the brushless motor 21 is parallel to the length direction of a transmission rod 34, one output end of the brushless motor 21 is connected with a transmission gear 22, the outer surface of the transmission gear 22 is engaged with a reduction gear 23, the key groove inner wall of the reduction gear 23 is fixedly connected with a main shaft 24, the main shaft 24 is rotatably connected with the fixed support 31 through a bearing, the length direction of the main shaft 24 is perpendicular to the length direction of the transmission rod 34, the edge of one side of the reduction gear 23 is connected with a pin shaft 25, and the transmission bearing 35 is sleeved on the outer surface of the pin shaft 25.

[0038] When the inflation operation is performed, the brushless motor 21 is started, the main shaft 24 is rotated under the meshing action of the transmission gear 22 and the reduction gear 23, at this time, the pin shaft 25 rotates, since the pin shaft 25 is eccentrically arranged, at this time, the transmission bearing 35 drives the transmission rod 34 to reciprocate along with the rotation of the pin shaft 25, so that the piston 33 reciprocates in the interior of the cylinder 32 and compresses the gas in the interior of the cylinder 32, the gas is pressed to enter the interior of the connecting barrel 51 through the one-way valve 50 and forms the inflation gas, then the inflation gas will enter the interior of the inflating assembly, and the inflation operation is performed on the bicycle tire through the inflating assembly.

[0039] It should be noted that the middle part of the fixed support 31 is provided with a circular hole, the transmission gear 22 passes through the interior of the circular hole, the tooth top circle diameter of the transmission gear 22 is smaller than the diameter of the circular hole, so that the operation of mounting the transmission gear 22 and the brushless motor 21 is relatively simple, the cylinder 32 and the fixed support 31 are both made of zinc alloy pressure casting, the zinc alloy has high strength and hardness, so that the cylinder 32 and the fixed support 31 are not easy to deform in the use process, the one-way valve 50 is located in the interior of the cylinder 32, the elastic sheet of the one-way valve 50 is riveted on the gas outlet of the cylinder 32, the connecting barrel 51 and the cylinder cover of the cylinder 32 are integrated, so as to ensure the connecting strength of the connecting barrel 51 and the cylinder 32.

[0041] When the inflation operation is performed on the bicycle, the gas nozzle 54 is connected with the bicycle tire inflation nozzle, the gas generated by the driving structure 20 and the inflating assembly 30 enters the interior of the gas outlet barrel 52 through the one-way valve 50 and the connecting barrel 51, then changes the flow direction of the inflation gas through the gas outlet barrel 52, and makes the inflation gas perform the inflation operation on the bicycle tire through the gas nozzle 54 and the bicycle tire inflation nozzle.

[0042] It should be noted that the bottom end of the air nozzle 54 is bent, and the bending angle of the air nozzle 54 is obtuse. Through the bent air nozzle 54, it is more convenient to connect with the bicycle tire inflation nozzle, and the angle of the air nozzle 54 can be adjusted through the connection degree of the air outlet cylinder 52 and the connecting cylinder 51, thereby more conveniently inflating the bicycle tire.

The airflow flowing inside the main machine 10 can quickly dissipate heat to the outside through the heat dissipation groove 101, thereby accelerating the heat dissipation speed inside the main machine 10 and avoiding the high temperature inside the main machine 10.

[0045] As Figure 3 A sealing ring 55 is arranged at the connection between the one-way valve 50 and the air cylinder 32. The sealing ring 55 is used to improve the sealing effect of the connection between the one-way valve 50 and the air cylinder 32.

[0046] As Figure 2 The main machine 10 is internally provided with a battery 11, and a control assembly is arranged on the main machine 10. The control assembly is electrically connected with the battery 11, and the control assembly and the battery 11 are electrically connected with the brushless motor 21. The control assembly is used to control the working state of the brushless motor 21.

[0047] As Figure 1 The control assembly includes a control switch 12 and two speed adjustment buttons 13. The control switch 12 is used to control the opening and closing of the brushless motor 21. The two speed adjustment buttons 13 are respectively an acceleration button and a deceleration button. The speed of the brushless motor 21 can be controlled through the speed adjustment button 13, thereby controlling the speed of inflating the bicycle tire.

[0048] The main machine 10 includes a bottom shell 14, a middle shell 15 and an upper shell 16. The middle shell 15 is connected with the bottom shell 14, and the upper shell 16 is connected with the side of the middle shell 15 away from the bottom shell 14.

[0049] When connecting the bottom shell 14, the middle shell 15 and the upper shell 16, the connection can be achieved through screws, so that the bottom shell 14, the middle shell 15 and the upper shell 16 are connected in a detachable manner. When maintenance is needed, the bottom shell 14 or the upper shell 16 can be separated according to the actual situation, thereby facilitating the maintenance operation of the parts inside the main machine 10.
