The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0023] The singular forms "a", "said" and "the" used in the specification include plural forms unless clearly indicated. The terms "include", "comprises" and "comprising" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features.

[0024] In the specification, when an element is referred to as being “on,” “fixed” to, “connected to,” “engaged to,” or the like, the element may be directly on, fixed to, connected to, engaged to, or contacting the other element, or intervening elements may be present.

[0025] The following will describe exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in a variety of different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all drawings, the same reference numerals represent the same or functionally identical elements.

[0026] Figure 1 The invention discloses an induction bottle valve, which is mainly composed of a valve body 10 and an integrated sensor mechanism 20 directly integrated on the valve body 10. The bottle valve is manual, and a hand wheel 11 for manually operating the bottle valve to open and close is also provided on the side of the valve body 10.

[0027] Figure 2 and Figure 3 The arrangement relationship between the integrated sensing mechanism and the valve body is shown. The integrated sensing mechanism 20 mainly obtains the pressure data inside the valve body 10 through the pressure sensor 21. A cross tube 12 with a four-way structure is arranged on the valve body 10. One end of the cross tube 12 is the gas outlet 13 of the bottle valve. The pressure sensor 21 is placed at the other end. Holes are also opened on the wall of the cross tube 12 to connect with the valve core 15 and the gas inlet 14. Figure 4 The valve core 15 and the air inlet 14 are the interception passage of the bottle valve, that is, no matter whether the valve core 15 is closed or not, the interception passage can reflect the actual pressure value in the bottle.

[0028] Specifically, a threaded end 21a is provided on the pressure sensor 21, and the pressure sensor 21 is fixed in the port of the transverse tube 12 by tightening the threaded end 21a. The sensing element 21b at the front of the threaded end 21a extends into the transverse tube 12 to reach the valve cavity position of the bottle valve (i.e., the intersection of the four-way structure), and detects the gas and liquid pressure flowing through the air inlet 14 and the air outlet 13. The integrated sensing mechanism 20 is fixed as a whole by the mounting seat 15 at the end of the transverse tube 12, that is, the housing 22 is fixed on the mounting seat 15 by fasteners, and a through hole 22a is opened at the bottom of the housing 22, so that the tail of the pressure sensor 21 is placed in the housing 22 through the through hole 22a, so as to be connected with the electronic module 24. A battery compartment 23 for powering the pressure sensor 21 and the electronic module 24 is provided in the housing 22, and the battery compartment 23 is preferably arranged on one side close to the inner wall of the housing 22, so as to free up the central space of the housing 22 for arranging the electronic module 24. Preferably, a CR2 lithium battery is used in the battery compartment 23. The electronic module 24 is composed of a circuit board 24a for processing the feedback data of the pressure sensor 21 and a display screen 24b for displaying the numerical value through a digital display. The display screen 24b also has a backlight low-pressure alarm function. When the pressure inside the gas cylinder drops to a preset safety threshold, the display screen will automatically light up the backlight and remind the user in a striking manner. This design not only improves the user's safety awareness, but also can promptly remind the user to replace or replenish the gas cylinder, thereby avoiding potential risks caused by insufficient pressure. The circuit board 24a has a high-performance microprocessor that can quickly and accurately process the pressure data from the sensor, and convert and analyze it into a digital signal. The final data is displayed through the display screen 24b to facilitate the user to view the status of the bottle valve in real time. The circuit board 24a can also be integrated with a Lora transmission module to realize a low-power, high-efficiency wireless remote data transmission function, and an alarm is issued when the pressure value or the integrated sensing mechanism 20 is abnormal. The upper part of the housing 22 is sealed by an upper cover 26 , and a mounting window 27 matching the display screen 24 b is hollowed out in the middle of the upper cover 26 so that the user can intuitively observe the data displayed on the display screen 24 b .
