Novel inflator

The invention discloses a novel inflator. The novel inflator comprises a push-pull rod, an air pipe and an air barrel, and is characterized in that one end of the air pipe is communicated with the air barrel, an inflating air outlet and a deflating air outlet are formed in the other end of the air pipe, each air outlet is provided with an electric valve, an air pressure sensor is arranged in the inflating air outlet, an air barrel base is provided with a controller, and the controller and the air pressure sensor are connected with the electric valves. According to the novel inflator, when the air pressure inside a tire reaches a preset value, the controller controls the electric valve of the inflating air outlet to be closed, the electric valve of the deflating air outlet is opened, the surplus air can be discharged through the deflating air outlet, the air pressure in the tire reaches the preset value, and the inflating needs to be stopped at the moment.
