[0026] Figure 1 An induction bottle valve is shown, which is mainly composed of a valve body 10 and an integrated sensing mechanism 20 directly integrated on the valve body 10. The bottle valve is manually operated, and a hand wheel 11 is further provided on the side of the valve body 10 for manually opening and closing the bottle valve.

[0027] Figure 2 And Figure 3 The arrangement relationship between the integrated sensing mechanism and the valve body is shown, and the integrated sensing mechanism 20 mainly acquires pressure data inside the valve body 10 through a pressure sensor 21. A cross pipe 12 with a four-way structure is provided on the valve body 10, one end of the cross pipe 12 is a gas outlet 13 of the bottle valve, the pressure sensor 21 is arranged in the other end, and holes are further provided on the wall surface of the cross pipe 12 and connected with a valve core 15 and an air inlet 14. In combination with reference Figure 4 The valve core 15 and the air inlet 14 are a trapped passage of the bottle valve, that is, the trapped passage can reflect the actual pressure value in the bottle whether the valve core 15 is closed or not.

[0028] Specifically, the pressure sensor 21 is provided with a threaded end 21a, which is screwed into the port of the cross pipe 12 to fix the pressure sensor 21, and the sensing element 21b at the front of the threaded end 21a extends into the cross pipe 12 to reach the valve cavity position of the cylinder valve (i.e. the intersection of the four-way structure), to detect the gas and hydraulic pressure flowing between the gas inlet 14 and the gas outlet 13. The integrated sensing mechanism 20 is fixed as a whole through the mounting seat 15 at the end of the cross pipe 12, that is, the shell 22 is fixed on the mounting seat 15 by fasteners, and a through hole 22a is formed in the bottom of the shell 22, so that the tail of the pressure sensor 21 is placed in the shell 22 through the through hole 22a to connect with the electronic module 24. The battery compartment 23 for supplying power to the pressure sensor 21 and the electronic module 24 is arranged in the shell 22, which is preferably arranged on one side close to the inner wall of the shell 22, so as to leave space in the central space of the shell 22 for arranging the electronic module 24. Preferably, CR2 type lithium batteries are used in the battery compartment 23. The electronic module 24 includes a circuit board 24a for processing the feedback data of the pressure sensor 21 and a display screen 24b for displaying the numerical value by digital display, and the display screen 24b also has a back light low pressure alarm function, when the pressure in the gas cylinder decreases to the preset safety threshold, the display screen will automatically light up the back light and remind the user in an eye-catching way. This design not only improves the safety awareness of the user, but also reminds the user to replace or supplement the gas cylinder in time, so as to avoid potential risks caused by insufficient pressure. The circuit board 24a has a high-performance microprocessor, which can quickly and accurately process the pressure data from the sensor, and convert and analyze it into a digital signal, and finally the data is displayed through the display screen 24b for the user to view the state of the cylinder valve in real time. The circuit board 24a can also be integrated with a Lora transmission module to realize low-power and high-efficiency wireless remote data transmission function, and alarm when the pressure value or integrated sensing mechanism 20 is abnormal. The upper part of the shell 22 is packaged by the upper cover 26, and the assembly window 27 matching the display screen 24b is hollowed out in the middle position of the upper cover 26, so that the user can directly observe the data displayed by the display screen 24b.
