They are usually made of high-strength steel and have pressure-resistant and corrosion-resistant properties to ensure the safe containment and transportation of LPG. These cylinders are usually designed in a cylindrical shape with specific capacity and pressure levels to meet the needs of different households.

[0003] After searching, the Chinese patent announcement number is: CN217082182U. This application discloses a shock-absorbing liquefied petroleum gas cylinder, which relates to the technical field of liquefied petroleum gas storage containers, and improves the problem that the existing liquefied petroleum gas cylinder is usually simple in structure, does not have the function of shock absorption, and is not conducive to transportation. It includes a bottle body, a shock-absorbing base is installed at the bottom of the bottle body, and a bottom protective sleeve is fixedly installed on the upper surface of the shock-absorbing base. The bottle body is plugged into the inside of the bottom protective sleeve, and a bottle body protective sleeve is detachably installed on the top of the bottom protective sleeve, and the bottle body protective sleeve is sleeved on the outer surface of the bottle body. This application stores the entire bottle body in the bottom protective sleeve and the bottle body protective sleeve through the coordinated arrangement of the bottom protective sleeve and the bottle body protective sleeve, which can play a good protective role for the entire bottle body, and it is not easy for the bottle body to be hit and dented, and it is not easy for the surface of the bottle body to be stained. Moreover, the arrangement of the shock-absorbing spring, when the bottle body is bumped and vibrated during transportation, the shock-absorbing spring plays a good shock-absorbing and buffering role in the vertical direction.

However, when the meal is ready, due to the fatigue of cooking, carelessness may occur, and the valve is not tightened and closed. At this time, the gas will be slowly released and leaked indoors. Long-term exposure to high concentrations of gas will cause poisoning, personal poisoning and other safety hazards. Therefore, a liquefied petroleum gas cylinder with a pressure sensing function is proposed to solve the above problems. Utility Model Content

The movable connection is provided with a connecting pipe 8 for providing connection, the outside of the connecting pipe 8 is fixedly connected with a baffle 9 for limiting, the outside of the baffle 9 is slidably connected to the inside of the movable hole 7, the outside of the connecting pipe 8 is sleeved with a telescopic spring 10 for providing spring force and rebound force, one end of the telescopic spring 10 is fixedly connected to the inner top of the movable hole 7, the other end of the telescopic spring 10 is fixedly connected to the top of the baffle 9, the bottom end of the connecting pipe 8 is fixedly connected with a sensor plate 11 for monitoring pressure, the bottom end of the sensor plate 11 is in contact with the top of the delivery pipe 4, the outside of the sensor plate 11 is slidably connected to the inside of the chamber 6, the top of the connecting pipe 8 is fixedly connected with a sensor 12 for detecting gas pressure, and the outside of the accommodating tube 3 is fixedly connected with a valve nozzle 13.

[0024] Reference Figure 4 The bottom end of the bottle body 1 is fixedly connected to a base 14 for providing a stable support and foundation. The inner wall of the bottom end of the base 14 is slidably connected to a plurality of connecting columns 15 for transmitting force. The top ends of the plurality of connecting columns 15 are fixedly connected to a limiting disk 16 for limiting the movement range of a subsequent strong spring 17. A strong spring 17 is arranged inside the base 14 for providing pressure or rebound force. The bottom ends of the plurality of connecting columns 15 are fixedly connected to a buffer seat 18 for absorbing impact or reducing vibration. The outside of the limiting disk 16 is slidably connected to the inside of the base 14, and the top of the buffer seat 18 is in contact with the bottom end of the base 14.

[0025] Working principle: When the valve is not tightened, the gas will still flow out from the inside of the delivery pipe 4, and only partially tightening will reduce the pressure of the gas leaking outward, and will not cause the sensor plate 11 to be pushed up, which can prevent the risk of gas leakage when it is not tightened. During normal use, the gas pressure will push up the sensor plate 11, and then make the connecting pipe 8 move, and the movement of the connecting pipe 8 will push up the sensor 12, which can make the user notice whether the valve is open or closed. When it is open, the sensor 12 will be pushed up, and when it is closed, the sensor 12 will drop down. It also drives the baffle plate 9 to move inside the movable hole 7, and the movement of the baffle plate 9 will cause the telescopic spring 10 to contract, and the contraction of the telescopic spring 10 will generate a rebound force to provide a force for the subsequent sensor plate 11 to recover. When the bottle body is installed, the buffer seat 18 will first contact the ground, and the gravity of the bottle body will cause the buffer seat 18 to be stressed, and the force of the buffer seat 18 will cause the connecting column 15 to move, and the movement of the connecting column 15 will drive the limit plate 16 to move, and the movement of the limit plate 16 will cause the strong spring 17 to be stressed, and the strong spring 17 will generate a rebound force to offset the force it receives.
