[0015] like Figure 1-2 As shown, this utility model is a brushless controller for an air pump, including a controller housing. A control chip 10 is disposed within the controller housing. The control chip 10 is connected to a power module 20, a display module 40, and a switching module 70. The power module 20 supplies power to the control chip 10 and the display module 40. The display module 40 displays the power level of the power module 20, the preset air pressure, the current air pressure, the air pumping mode, and a fault indicator. The switching mode is used to switch between different air pumping modes. The power module 20 is connected to a voltage sensor 30 to detect the voltage value of the power module 20. The control chip 10 is connected to a current sensor 60 and a temperature sensor to detect the current and temperature of the control chip 10. The display module 40 is an LCD screen.

[0016] In this utility model, the inflation modes include: car mode 701: default 3.0 BAR, pressure not adjustable; basketball mode 703: default 2.0 BAR, pressure not adjustable; bicycle mode 702: default 4.5 BAR, pressure not adjustable; nail gun mode 704: default 7.0 BAR, pressure not adjustable; and custom mode 705: setting range 2-8 BAR.

[0017] In this utility model, the display module 40 is also provided with function buttons, including buttons S1, S2, S3 and S4. The function buttons are electrically connected to the control chip 10. Button S1 is a power on / off button and a unit conversion button; button S2 is a pressure increase button; button S3 is a pressure decrease button; and button S4 is a mode switching button.

[0018] In this invention, the power module 20 is a lithium battery pack.

[0019] In this invention, the controller also includes a brushless drive board for driving the brushless motor of the air pump for inflation.

[0020] like Figure 1 As shown, in this utility model, the upper left corner of the display screen shows the current battery pack power level; the middle section shows the pressure (2.0-8.0 BAR converted to 29-116 PSI); the three on the right are fault indicators, from top to bottom: battery pack undervoltage fault indicator, controller current fault indicator, controller high temperature fault indicator; and the bottom displays five modes, from left to right:

[0021] Car Mode 701: Default 3.0 BAR, pressure not adjustable;

[0022] Basketball Mode 703: Default 2.0 BAR, pressure not adjustable;

[0023] Bike mode 702: Default 4.5 BAR, pressure not adjustable;

[0024] Pneumatic nail gun mode 704: Default 7.0 BAR, pressure not adjustable;

[0025] Custom mode 705: Set range 2-8 BAR.

[0026] There are four buttons on the right side of the display screen, from top to bottom:

[0027] S1: Power on / off / unit switching button. Press and hold for 1 second to power on, press and hold for 3 seconds to power off (motor stops working, backlight turns off, LCD displays current status) (button is active when pressed); short press to set unit when powered on (button is active when released); button is inactive when switching modes.

[0028] S2: "+" key

[0029] S3: "-" key

[0030] S4: Mode switching button. Press and hold for two seconds to enter the mode setting state. The pressure setting and the corresponding mode icon will flash. Press the mode button briefly to switch modes. Press and hold for 2 or 3 seconds without pressing any button to confirm the current mode and exit the setting mode.

[0031] 1. When the machine is powered on, the LCD screen displays the current status. Before the ON / OFF button is turned on, other function keys cannot be operated. When the machine is powered on, the backlight is on. It turns off after 10 seconds of inactivity. When there is operation, the backlight is on. The backlight is always on when the machine is running.

[0032] 2. Charging will begin when the cylinder pressure is detected to be 1 bar lower than the set pressure.

[0033] 3. When the cylinder pressure is detected to be 0.3 BAR higher than the set pressure, the discharge is activated.

[0034] 4. Parameter setting status:

[0035] Short press the + / - button: 0.1 BAR;

[0036] Long press the + / - button: 0.5 BAR.

[0037]

[0038]

[0039] This invention includes a switching module that categorizes the objects to be inflated. When faced with different objects or different inflation needs, the corresponding inflation mode can be switched, making adjustments quicker. It also has an adjustment capability, allowing adjustments to be made even when the inflation need does not require switching modes. Furthermore, existing controllers display air pressure using pointers, which lacks precision. This invention uses an LCD screen for a more intuitive display.
