[0021] As Figures 1 to 4 shown, this embodiment provides an improved plug structure for an electronic tire pressure gauge, including: a plug body 2 installed on the front side of the housing 1; specifically, a pressing head 11 is installed at the front end of the housing 1; the rear part of the plug body 2 is installed in the pressing head 11; the forward air inlet pipe 22 and the outer limit pipe 23 of the plug body 2 protrude from the pressing head 11 for convenient use. The plug body 2 includes a rear detection part 21, a forward air inlet pipe 22 and an outer limit pipe 23 that are integrally connected; a detection cavity is provided in the rear detection part 21 and a micro pressure sensor 211 is installed inside the detection cavity; the forward air inlet pipe 22 is integrally communicated with the detection cavity, so that the micro pressure sensor 211 can smoothly detect the gas pressure input by the forward air inlet pipe 22; an outer limit pipe 23 is integrally connected coaxially to the outside of the front part of the forward air inlet pipe 22, and the outer limit pipe 23 effectively limits the valve core and the copper nut outside the valve core; a sealing ring 24 is installed between the forward air inlet pipe 22 and the outer limit pipe 23; the end of the forward air inlet pipe 22 extends out of the end of the sealing ring 24; an air inlet side port 221 is opened on the side surface of the end of the forward air inlet pipe 22. During actual use, when the valve core of the tire is offset to block the forward air inlet pipe 22, since the air inlet side port 221 is opened on the side surface of the end of the forward air inlet pipe 22, the gas flowing out of the valve core can smoothly enter the forward air inlet pipe 22 from the air inlet side port 221, meeting the detection standard and preventing inaccurate readings caused by the valve core nozzle blocking the air inlet hole, which is convenient and practical; during this process, the copper nut outside the valve core tightly presses against the sealing ring 24 to achieve good sealing and ensure that the gas flowing out of the valve core enters from the port of the forward air inlet pipe 22 or the air inlet side port 221.
[0022] Please refer to Figure 2 and Figure 4As shown, the intake side port 221 is located on the front side of the end of the sealing ring 24, that is, the depth of the intake side port 221 reaches the end of the sealing ring 24; this prevents air leakage from the sealing ring 24 when gas passes through the intake side port 221, ensuring a good sealing effect. More specifically, the width of the intake side port 221 is 0.7 - 2 times the inner diameter of the forward intake pipe 22.

More specifically, a display screen 12 is installed on the side of the housing 1; a battery compartment 13 is provided at the tail of the housing 1; a battery is installed in the battery compartment 13; the battery powers the micro pressure sensor 211 and the display screen 12; a switch 14 is provided on the lower side of the housing 1; the display screen 12 is provided for convenient observation of the readings.

The intake side port 221 is located on the front side of the end of the sealing ring 24, preventing air leakage from the sealing ring 24 when gas passes through the intake side port 221, ensuring a good sealing effect.
