[0029] See Figures 1-5 , an automatic start-up air pump is proposed in the embodiments of the present utility model. When the air pipe 60 is pulled out, the automatic start-up air pump can automatically start the air inflation core 40 without user operation, which is very convenient and can effectively avoid accidental touch. To achieve the above technical purposes, the automatic start-up air pump includes a control board 10, a Hall switch sensor 20, a magnetic part 30, an air inflation core 40, a pipe sleeve 50, and an air pipe 60. The specific structure is introduced as follows:

[0030] The control board 10 is connected to the Hall switch sensor 20 and the air inflation core 40. The Hall switch sensor 20 is configured as a start switch for the air inflation core 40. When the Hall switch sensor 20 detects the magnetic part 30, it sends a signal to the control board 10 to turn off the air inflation core 40. When the Hall switch sensor 20 does not detect the magnetic part 30, it sends a signal to the control board 10 to start the air inflation core 40.

[0031] The pipe sleeve 50 is connected to the air outlet interface 41 of the air inflation core 40; for example, it can be connected by threads, and the present utility model does not specifically limit it. The Hall switch sensor 20 is arranged on one side of the pipe sleeve 50, for example, arranged at one end close to the connection between the pipe sleeve 50 and the air outlet interface 41. At the same time, to avoid air leakage, a third sealing ring 170 is provided between the pipe sleeve 50 and the air outlet interface 41 of the air inflation core 40. The air outlet interface 41 refers to the interface through which the air inflation core 40 outputs gas.

[0032] The magnetic member 30 is provided on the air tube 60, and the magnetic member 30 can move along with the air tube 60. The first end 61 of the air tube 60 is slidably provided in the tube sleeve 50, and the second end 62 of the air tube 60 is provided outside the tube sleeve 50. Wherein, by pulling the air tube 60 out of the tube sleeve 50, the magnetic member 30 is separated from the detection range of the Hall switch sensor 20, and the Hall switch sensor 20 drives the control board 10 to start the inflation mechanism 40.

[0033] In the technical solution of the embodiment of the present invention, by pulling the air tube 60 out of the tube sleeve 50, the magnetic member 30 is separated from the detection range of the Hall switch sensor 20. When the Hall switch sensor 20 does not detect the magnetic member 30, it sends a signal to the control board 10 to start the inflation mechanism 40, so that the control board 10 starts the inflation mechanism 40. At the same time, when the air tube 60 is retracted into the tube sleeve 50, the magnetic member 30 enters the detection range of the Hall switch sensor 20. When the Hall switch sensor 20 detects the magnetic member 30, it sends a signal to the control board 10 to close the inflation mechanism 40, so that the control board 10 closes the inflation mechanism 40.

[0034] It can be seen that through the technical solution of the embodiment of the present invention, when the air tube 60 is pulled out, the inflation mechanism 40 can be automatically started without user operation, which is very convenient and can effectively avoid accidental touch.

Specifically, the connecting nut 140 is used to connect an external object to be inflated, such as a tire, which is not specifically limited in the present utility model. The taper connector 130 is used to connect the trachea 60 and the connecting nut 140.

[0043] Through the second tracheal clamp 150, the second end 62 of the trachea 60 can clamp the taper connector 130, greatly increasing the friction force, thereby achieving reliable fixation.

[0044] Further, the self - starting air pump further includes a second sealing ring 160, and the second sealing ring 160 is clamped and disposed between the taper connector 130 and the connecting nut 140.
