DETAILED DESCRIPTION

[0016] The preferred examples of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred examples described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0017] like Figure 1 As shown, the tire inflation device with temperature detection of the present invention comprises an air source device 1, an exhaust valve 22 and a controller 5. One end of the air source device 1 is connected to the air nozzle 3 through the air pipe 2, and the other end of the air nozzle 3 is connected to the tire. The air source device 1 comprises an air intake valve 21, a pressure sensor 6, and a compressor with an air storage tank. The air intake valve 21, the exhaust valve 22 and the pressure sensor 6 are respectively connected to the air path of the air pipe 2, and the pressure sensor 6 can measure the tire pressure of the tire. Opening the air intake valve 21 can inflate the tire by passing the gas through the air pipe 2 and the air nozzle 3 in sequence, and opening the exhaust valve 22 can deflate the tire.

[0018] A temperature sensor 4 is provided in the air pipe 2, and the controller 5 is connected to the temperature sensor 4, the air inlet valve 21, the air exhaust valve 22, and the pressure sensor 6. Specifically, the temperature sensor 4 includes a temperature sensing head 41 and a wire 42 connected to the temperature sensing head 41. The temperature sensing head 41 is provided in the air pipe 2 and is located close to the air nozzle 3. The air exhaust valve 22 is provided between the temperature sensing head 41 and the air source device 1. The wire 42 is partially arranged inside the trachea 2, and the part inside the trachea 2 is laid along the trachea 2 and connected to the controller 5 circuit, so that by opening the exhaust valve 22, the temperature sensor 41 can sense and measure the temperature of the gas flowing through the trachea 2, thereby achieving that when the user uses the inflation device to inflate the tire, the gas can be briefly deflated first. During deflation, the gas passes through the temperature sensor 41 in the trachea 2, and the temperature sensor 41 sends a signal to the controller 5. The controller 5 closes the exhaust valve 22, and the controller 5 controls the air source device 1 to adjust the inflation setting tire pressure value according to the measured temperature to inflate the tire, thereby achieving precise inflation with the best effect. This solution has low implementation cost and is easy to operate.

[0019] The air source device 1 can also be an inflatable treasure with inflation pressure control. In this case, the pressure sensor 6 and the air inlet valve 21 are not required, and the controller 5 can also share the controller of the inflatable treasure.

[0020] The inflation method of the tire inflation device with temperature detection of the present invention uses the above-mentioned inflation device. Specifically, the method comprises the following steps: S1: Connect the air nozzle 3 to the tire; S2: Open the exhaust valve 22 through the controller 5 to deflate the tire; S3: The controller 5 measures the temperature of the gas flowing through the gas pipe 2 through the temperature sensing head 41 of the temperature sensor 4; S4: the controller 5 closes the exhaust valve 22, and starts the controller 5 to control the air source device 1 to adjust the inflation setting tire pressure value according to the temperature measured by S3 to inflate the tire, thereby achieving accurate inflation and optimal tire pressure effect.
