Detailed Description

The following description of preferred embodiments of the present utility model is provided in connection with the accompanying drawings, and it is to be understood that the preferred embodiments described herein are for the purpose of illustration and explanation only and are not intended to limit the utility model thereto.

As shown in fig. 1, the tire precise air charging device of the utility model comprises an air source 1, at least two air charging valves 21 and 22 connected in parallel and an air charging pipe 3. Specifically, the air source 1 can be a compressor or an inflator with an air storage tank, the air outlet ends of the air source are connected with the air inlet ends of the air charging valves 21 and 22, the air outlet ends of the air charging valves 21 and 22 are connected with the air inlet pipe of the air charging pipe 3, and the air outlet end of the air charging pipe 3 is connected with a tire to realize inflation of the tire.

The two inflation valves 21 and 22 are on-off, in the use process, the two inflation valves 21 and 22 can be controlled to rapidly inflate the tire at first, and when the set air pressure is close, one of the inflation valves 21/22 is controlled to inflate, so that the inflation quantity is reduced, and the inflation accuracy is controlled conveniently.

Furthermore, when inflating a larger vehicle tire, both inflation valves 21, 22 may be controlled simultaneously, while when inflating some smaller tires, one of the inflation valves 21/22 may be controlled separately.

Further, the two inflation valves 21, 22 have different air flow paths, so that the flow rates of the two inflation valves are different, and then several inflation working modes with different flow rates of the present inflation device can be led out:

high flow inflation mode: simultaneously, two inflation valves 21 and 22 are controlled to inflate, so that rapid inflation is realized;

medium flow inflation mode: the inflation valve 21/22 with larger flow rate is independently controlled to inflate;

small flow inflation mode: the inflation valve 21/22 with smaller flow rate is independently controlled to inflate, so that accurate inflation is realized.

In this scheme, the inflation tube 3 is also connected with a pressure sensor 4 for detecting the air pressure of the tire, and the pressure sensor 4 is connected with a controller 6 in a circuit and detects the air pressure of the tire in a period when the inflation valve 21/22 is closed.

The inflation tube 3 is also connected with a deflation valve 5 in a gas path, and a user can deflate the excessively inflated tire through the deflation valve 5. The air release valve 5 is also connected with a controller 6 in a circuit mode, and the controller is simultaneously connected with the inflation valves 21 and 22 in a circuit mode, so that a user can control all parts to work and operate through the controller 6.

Finally, it should be noted that: the foregoing is merely a preferred example of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
