Abstract

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.

Example Embodiment

[0008] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.
[0009] Such as figure 1 As shown, a new type of pump includes a push-pull rod 1, a trachea 2, and a pump 3. One end of the trachea 2 communicates with the pump 3, and the other end is provided with a pump outlet 4 and a deflation outlet 5, each of which is separate An electric valve is provided, the pump air outlet is provided with an air pressure sensor, the air cylinder base is provided with a controller, and the controller is connected with the air pressure sensor and the electric valve.
[0010] The air pressure value is fed back to the controller through the air pressure sensor. When the air pressure in the tire reaches the preset value, the controller controls the electric valve of the air outlet to close and the electric valve of the air outlet to open, and the excess air is discharged through the air outlet, indicating The air pressure in the tire has reached the preset value, and the inflation needs to be stopped at this time, which is convenient to use.
[0011] It can be known from technical common sense that the present invention can be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the above-disclosed embodiments are only illustrative in all aspects, and not the only ones. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
