[0035] Reference Figures 1 to 10 , according to a preferred embodiment of the present invention, a bicycle electric air pump, where it should be noted that the structure of the bicycle electric air pump is as Figure 1As shown in the figure, the bicycle electric air pump includes a housing 10, the housing 10 has a first cavity, both ends of the first cavity communicate with the outside, and one end of the housing 10 has a first mounting hole, and the other end has a second mounting hole. Both the first mounting hole and the second mounting hole communicate with the first cavity, and the size of the first mounting hole is smaller than the size of the second mounting hole. It is worth mentioning that the bicycle electric air pump further includes two cover plates 20, and the two cover plates 20 are respectively arranged at the upper end and the lower end of the housing 10 to close both ends of the first cavity. It should be noted that one of the cover plates 20 is also close to the second mounting hole, and the bicycle electric air pump further includes an air pump assembly 30. The air pump assembly 30 is arranged in the first cavity, and the bottom of the air pump assembly 30 is fixedly connected to the cover plate 20 close to the second mounting hole, thereby defining the position of the air pump assembly 30.

[0036] Further, the air pump assembly 30 includes a nozzle connecting frame 31. The nozzle connecting frame 31 is fixed on the cover plate 20 close to the second mounting hole. In addition, the top of the nozzle connecting frame 31 has a cavity 3101. At the same time, one side of the nozzle connecting frame 31 has a first connection hole 3102, and the bottom wall forming the first connection hole 3102 has a second connection hole 3103. The bottom wall forming the second connection hole 3103 has a plurality of uniformly distributed first ventilation holes 3104, and the plurality of first ventilation holes 3104 all communicate with the cavity 3101. At the same time, the first connection hole 3102 is aligned with the second mounting hole.

[0037] Further, the air pump assembly 30 further includes a thimble 32, a silica gel pad 33 and a connecting nozzle 34. One end of the thimble 32 is placed in the second connection hole 3103, and the other end is placed in the first connection hole 3102. The silica gel pad 33 is placed in the first connection hole 3102, and the thimble 32 also penetrates through the silica gel pad 33. One end of the outer wall of the connecting nozzle 34 is threadedly connected to the inner wall forming the first connection hole 3102. At the same time, the center of the connecting nozzle 34 has a through hole, and the end of the silica gel pad 33 facing away from the second connection hole 3103 is placed in the through hole, that is, the user can cooperate with the through hole of the connecting nozzle 34 with the nozzle of the external tire.

[0038] Those skilled in the art should understand that the air pump assembly 30 further includes an air cylinder 35. The air cylinder 35 is vertically arranged, and the bottom of the air cylinder 35 is disposed in the cavity 3101. The top of the air cylinder 35 has a second cavity 3501, and the bottom wall forming the second cavity 3501 has a second ventilation hole 3502. The second ventilation hole 3502 is also communicated with the cavity 3101. As Figure 8 shown, the second ventilation hole 3502 is also eccentrically arranged. Additionally, an air valve plate 36 is fixed to the bottom of the air cylinder 35, and the air valve plate 36 covers the second ventilation hole 3502. Further, the above-mentioned air valve plate 36 is a stainless steel plate.

[0039] It should be noted that the air pump assembly 30 further includes a crank assembly 37 and a driving component 38. One end of the crank assembly 37 is placed in the second cavity 3501, and the other end is connected to the driving component 38. The end of the crank assembly 37 placed in the second cavity 3501 is arranged to be movable up and down by a predetermined distance. That is, when the crank assembly 37 moves downward, the end of the crank assembly 37 placed in the second cavity 3501 blocks the end of the second ventilation hole 3502 connected to the second cavity 3501. At this time, the air valve plate 36 will be subjected to the acting force of air pressure, so that the air valve plate 36 deforms in a direction away from the second ventilation hole 3502, thereby causing the air valve plate 36 to no longer block the second ventilation hole 3502, and enabling the air flow to be guided to the cavity 3101 through the second ventilation hole 3502. Additionally, as Figure 7 shown, the thimble 32 has a plurality of air holes, and the plurality of air holes are communicated with the plurality of first ventilation holes 3104, so that the air flow entering the cavity 3101 is guided to the external tire through the above-mentioned thimble 32. Those skilled in the art should understand that when the end of the crank assembly 37 placed in the second cavity 3501 moves upward, the end of the crank assembly 37 placed in the second cavity 3501 no longer blocks, and at the same time, the air valve plate 36 is subjected to the acting force of the air flow, so that the air valve plate 36 tightly adheres to the bottom of the air cylinder 35, thereby blocking the second ventilation hole 3502.

[0040] Specifically, the above-mentioned crank assembly 37 includes a crank gland 371, a crank 372, and an eccentric wheel 373. One end of the crank 372 is fixedly connected to the crank gland 371, and the crank gland 371 is placed in the second cavity 3501 and faces the second ventilation hole 3502, and the crank gland 371 is arranged to be able to block the second ventilation hole 3502. Additionally, the other end of the crank 372 is located above the air cylinder 35 and is hingedly connected to one end of the eccentric wheel 373. AsFigure 10 As shown, the connection between the crank 372 and the eccentric wheel 373 can be implemented as a bearing and a shaft rod. That is, the bearing is sleeved on the end of the crank 372. At the same time, one end of the shaft rod is fixed on the eccentric wheel 373, and the other end is movably connected to the bearing, that is, the bearing can rotate on the shaft rod. In addition, it should be noted that the center of the eccentric wheel 373 is also fixedly connected to the driving component 38, and the driving component 38 is arranged to drive the eccentric wheel 373 to rotate. Those skilled in the art should understand that the driving component 38 can be implemented as a small motor. That is, when the driving component 38 operates, the eccentric wheel 373 rotates. It should also be noted that the transverse cross-sectional dimension of the end of the crank 372 that cooperates with the crank gland 371 is smaller than the dimension of the second cavity 3501.

[0041] Specifically, the crank assembly 37 further includes a frame 374. The frame 374 has a first connection portion and a second connection portion. The first connection portion and the second connection portion are perpendicularly arranged. The first connection portion has an insertion hole. The end of the crank 372 facing away from the second cavity 3501 passes through the insertion hole and faces the second connection portion. The driving component 38 is fixed on the side of the second connection portion facing away from the first connection portion. The eccentric wheel 373 is rotatably arranged on the side of the second connection portion close to the first connection portion. Those skilled in the art should understand that the driving component 38 has a rotating shaft. The rotating shaft penetrates the second connection portion and is fixedly connected to the center of the eccentric wheel 373, so as to drive the eccentric wheel 373 to rotate.

[0042] In addition, it should be noted that a PCB control board 100 is also arranged in the first cavity. The PCB control board 100 also has a charging interface. At the same time, the bottom of the cover plate 20 near the second mounting hole also has a wiring port. The wiring port faces the charging interface. One side of the PCB control board 100 is also provided with a storage battery 200. In addition, a button switch 300 is installed on the first mounting hole.
