In this embodiment, the second end of the motor housing 21 is used as the base body, which not only facilitates the integrated assembly of the motor controller 3 and the motor 2, making the structure more compact and stable, but also can reduce the cable length between the motor 2 and the motor controller 3, avoid the collision between the cable and the outer shell 1 during operation to generate noise, and at the same time reduce the cable fixing structure, making it more convenient for later assembly. This embodiment more effectively utilizes the space inside the outer shell 1, improves the space utilization rate, and avoids interference between the motor controller 3 and other components inside the outer shell 1.

The control panel 4 is connected to the lamp assembly 5. The lamp assembly 5 has a plurality of lamp bodies 51, and the plurality of lamp bodies 51 are used to respectively display different working states.

[0047] The air pump 100 of this embodiment can prompt the user of the phased working state of the air pump 100 through information such as the color and blinking frequency of different lamp bodies 51, so as to facilitate the user to obtain the current working condition of the air pump 100.

[0052] The output end 231 of the motor shaft 23 is in driving connection with the air supply unit in the air pump 100. The air supply unit may be a piston cylinder, the piston rod of which is in driving connection with the output end 231 of the motor shaft 23, thereby converting the rotational motion of the motor shaft 23 into the linear reciprocating motion of the piston rod, and realizing the suction and exhaust through the reciprocating movement of the piston in the piston cylinder. After the motor 2 is powered on, the output end 231 of the motor shaft 23 outputs torque, and drives the air supply unit to move to provide compressed gas, and the compressed gas flows out through the outlet flow channel in the housing 1.

During assembly, the two second connecting holes 321 on the PCB board 32 are first aligned and plugged with the positioning pins 313 to achieve pre-assembly, and then bolts and other connecting parts are arranged in the corresponding second connecting holes 321 and the first connecting holes 314 to fix the PCB board 32 on the base 31.

[0055] The positioning pin 313 is provided in this embodiment to facilitate the subsequent assembly and positioning, improve the assembly efficiency and positioning accuracy, and improve the structural stability of the motor 2 and the motor controller 3.

[0056] The electrical components include a pressure sensor 33, an overload protector 34, a relay 35, and a temperature sensor 36. The PCB board 32 is provided with an air pipe joint 38, and the air pipe joint 38 can be fixedly connected to the PCB board 32 through connecting parts such as bolts. The pressure sensor 33 can be integrated on the PCB board 32. The pressure sensor 33 is connected to the first end of the air pipe joint 38. In order to improve the sealing performance, an annular sealing ring can be provided at the first end of the air pipe joint 38 to prevent air leakage after the air pipe joint 38 abuts against the pressure sensor 33. The second end of the air pipe joint 38 is communicated with the air outlet flow channel in the housing 1. The pressure sensor 33 can obtain the air pressure value in the air outlet flow channel in real time, so as to determine the current air pumping pressure of the air pump 100. The pressure sensor 33 can transmit the detected data to the control panel 4, and display it on the control panel 4 or show it through the lamp assembly 5.

[0057] The base 31 is generally strip-shaped. The two ends of the base 31 in the length direction are generally flush with the outer circumference of the rear end cover 211, and there is a certain distance between the two sides of the base 31 in the width direction and the outer circumference of the rear end cover 211. The outer peripheral side of the base 31 is provided with a mounting portion 312. Specifically, the mounting portion 312 is provided on one side of the base 31 in the width direction, and the outer edge of the mounting portion 312 can be generally flush with the outer circumference of the rear end cover 211.

[0058] The mounting portion 312 is a generally L-shaped plate. An installation groove 3121 is defined between the mounting portion 312 and the side wall of the base 31.

The temperature sensor 36 is arranged on the side of the PCB board 32 facing the motor housing 21, and the temperature sensor 36 is arranged corresponding to the through hole 311. The temperature sensor 36 can be closer to the rear end cover 211 of the motor 2 through the through hole 311, which is convenient for more accurately collecting the working temperature of the motor 2.

[0060] In this embodiment, by integrating the motor controller 3 at the second end of the motor housing 21, the space in the axial direction of the motor 2 is fully utilized to achieve the integrated design of the motor 2 and the motor controller 3. In this embodiment, the rear end cover 211 at the second end of the motor housing 21 is used as the base body, which not only facilitates the integrated assembly of the motor controller 3 and the motor 2, making the structure more compact and stable, but also can reduce the cable length between the motor 2 and the controller, avoid collision between the cable and the housing 1 during operation to generate noise, and at the same time reduce the fixing structure for the cable and the space occupied by the cable, which is convenient for later assembly.

[0061] This embodiment can make more effective use of the space inside the housing 1, improve the space utilization rate, and avoid interference between the motor controller 3 and other components inside the housing 1. The air pump 100 of this embodiment can integrate the air pressure sensor 33, the overload protector 34, the relay 35, and the temperature sensor 36 on the rear end cover 211 of the motor 2 when the inner cavity space is limited, so that the air pump 100 has functions such as air pressure detection, temperature detection, overload protection, and motor control.

[0064] In this embodiment, the lamp assembly 5 and the control panel 4 are both arranged on the outer wall of the housing 1, and the lamp assembly 5 is connected to the control panel 4. The lamp assembly 5 includes a plurality of lamp bodies 51, a light transmission ring 52 arranged on the housing 1, and an outer cover 53. The light transmission ring 52 and the outer cover 53 are sequentially arranged outside the lamp body 51, and the lamp body 51 can be an RGB lamp bead. The light transmission ring 52 can be made of PC material, and the light transmission ring 52 contains a certain amount of diffusion powder, so that a softer light effect can be obtained when the lamp assembly 5 emits light.

[0065] A plurality of lamp bodies 51 are used to respectively display different working states of the air pump. Specifically, the plurality of lamp bodies 51 include a first lamp body, a second lamp body, a third lamp body, a fourth lamp body, a fifth lamp body, and a sixth lamp body. The number of the first lamp body, the second lamp body, the third lamp body, the fourth lamp body, the fifth lamp body, and the sixth lamp body can all be two. The 12 lamp bodies 51 are evenly distributed in a circular shape along the circumferential direction, and the same lamp bodies can be arranged opposite to each other to improve the visual effect of the light. The colors of the lamp bodies for displaying different working states can be different and / or the flashing frequencies can be different. In application, the lighting performance of different lamp bodies can be controlled by programming, supporting users to customize a variety of RGB modes, making the light emitted by different lamp bodies more recognizable and improving the user experience.

[0066] The first lamp body is used to display the air pressure state from 0 to the first threshold value, and the first threshold value can be 50% to 80% of the preset saturated air pressure. For example, the first threshold value is 50%, 66%, 74%, or 80% of the preset saturated air pressure. Preferably, in this embodiment, the first threshold value is 70% of the preset saturated air pressure. The first lamp body can be a green light lamp. When the air pressure during the air pumping of the air pump is between 0 and 70% of the preset saturated air pressure, the first lamp body slowly flashes, which can prompt the user that the current is in the inflation state, and the current inflation air pressure is relatively low and it still takes some time to be filled, and just wait patiently.

[0067] The second lamp body is used to display the air pressure state from the first threshold value to the second threshold value. The second threshold value can be 90% to 98% of the preset saturated air pressure. For example, the second threshold value is 90%, 93%, 97%, or 98% of the preset saturated air pressure. Preferably, in this embodiment, the second threshold value is 95% of the preset saturated air pressure. The second lamp body can be a yellow light lamp. When the air pressure during the air pumping of the air pump is between 70% of the preset saturated air pressure and 95% of the preset saturated air pressure, the second lamp body slowly flashes, which can prompt the user that the current inflation air pressure is close to the saturated air pressure and the working state of the air pump needs to be concerned.

[0068] The third lamp body is used to display the air pressure state from the second threshold value to the preset saturated air pressure. The third lamp body can be a red light lamp. When the air pressure during the air pumping of the air pump is between 95% of the preset saturated air pressure and 100% of the preset saturated air pressure, the third lamp body slowly flashes, which can prompt the user to turn off the air pump, or prompt the user that the air pump will automatically stop working soon and the inflation operation of the next tire can be carried out.

[0069] The fourth lamp body is used to display the deflation state. The fourth lamp body can be a blue light lamp. When the blue light slowly flashes, it can prompt the user that the current is in the deflation state.

[0070] The fifth lamp body is used to display the resting state. The fifth lamp body can be a white light lamp. When the white light is constantly on, it can prompt the user that the current state is the resting state (non-working state). The fifth lamp body can also be set as a breathing lamp, a running horse lamp, a multi-color constant light lamp, etc.

[0071] The sixth lamp body is used to display the abnormal state. The sixth lamp body can be a red light lamp. When the red light is constantly on, it can prompt the user that the air pump has an abnormal state, such as overheating, hardware error reporting, too high air pressure and other faults, which is convenient for the user to take measures as soon as possible.

[0072] In this embodiment, the control panel 4 has a display panel 41, a mode indicator light 45, a button 42, a first interface 43 and a second interface 44. The first interface 43 is connected to the motor controller 3, and the second interface 44 is connected to the lamp assembly 5. The button 42 can be used for mode adjustment and function setting, and can also be used as a start / stop button. The mode indicator light 45 can display the current mode state by being constantly on. The display panel 41 can display information such as air pressure unit and air pressure value, which is convenient for the user to make personalized settings, can be applied to different working conditions, and has good practicability.

[0073] The control panel 4 can feedback the working state information of the air pump 100 obtained to the user through the color, flashing frequency, etc. of the lamp body, prompt the user of the phased working state of the air pump, so as to facilitate the user to obtain the current working condition of the air pump. By providing various forms of information feedback, it helps the user to have sufficient time to perform operations on the air pump, improves the user's awareness of the working state of the air pump, and improves the user experience.
