What is the reason for the air pump not inflating?

The reason why the air pump does not inflate is: the built-in spring plate of the air pump has softened over time. When the pressure in the air storage tank reaches a certain level, the softened spring plate cannot spring back due to the counter pressure from the air storage tank. It could also be that the tube of the air pump is clogged. The solution is to directly replace the air pump pipeline. The onboard air pump is also called an inflator, air compressor, or air pump. It works by the operation of the internal motor. Its working principle is: when the motor operates to pump air, the valve of the connecting pipe is pushed open by the atmospheric pressure, allowing gas to enter the air cylinder. When inflating the tire, the valve is closed by the pressure inside the air cylinder, and the gas enters the tire.
I've used many air pumps before, and the main reasons for not inflating are power connection issues, problems with the pump itself, or air hose leaks. For example, insufficient battery power or loose wire connections can cause a power interruption, and the pump may not respond at all. Another common issue is the pump being clogged with dust or debris, especially when used outdoors or when the cover isn't properly secured; or the valve getting stuck, preventing normal suction and discharge. Also, check if the air hose has any cracks or if the connectors aren't tightened properly, as even a small leak can render the entire system ineffective. I recommend first using a flashlight to carefully inspect the connections to ensure they're secure, then try restarting the device if possible. If the problem persists, for safety's sake, seek professional repair instead of forcing it to work to avoid further damage. Regular cleaning of the pump and avoiding direct sunlight can also extend its lifespan.
From a tool perspective, a non-working air pump is usually due to three points: electrical circuit failure, mechanical damage, or air pathway blockage. On the electrical side, check the plug, fuse, or overload switch—overheating may trigger automatic power-off protection. In the mechanical section, pistons or fans getting stuck by dirt is common, especially after use in dusty environments without cleaning; pump casing wear can also reduce sealing, leading to insufficient air pressure. As for the air hose part, aging connectors or damaged rubber rings are prevalent—a simple method is to press the hose by hand and listen for air leakage sounds. I often remind users to test whether the power indicator light is on themselves; if there's no response, prioritize checking the wiring, and if there's a slight rotating sound, then inspect the pump core. Long periods of inactivity can easily cause issues, so it's recommended to power it on and run it for a few minutes regularly for maintenance.
