Description

Technical Field

[0001] This invention belongs to the field of pressurized fire extinguishing bottles, and specifically relates to a fire extinguishing device that can adaptively adjust the size of the bottle opening based on the adaptive size bottle opening structure of the pressurized fire extinguishing bottle under changes in internal pressure. Technical Background

[0002] The spray volume per unit time of a pressurized fire extinguishing bottle is usually affected by both the internal pressure and the size of the bottle opening. However, the opening size of a traditional pressurized fire extinguishing bottle is fixed, and as the internal pressure gradually decreases, the spray volume per unit time will decrease significantly. This situation may affect the spraying effect and is not conducive to achieving continuous and stable spraying. Therefore, developing a device that can automatically adjust the opening size according to changes in internal pressure will greatly improve the spraying effect of pressurized fire extinguishing bottles. Summary of the Invention

[0003] This invention provides an adaptive bottle opening structure that can automatically adjust the opening area of ​​the bottle opening according to the pressure inside the bottle, so that the spray volume remains stable as the pressure inside the bottle decreases; this invention forms a variable opening at the bottle opening through a shielding mechanism, thereby achieving stable spraying during use.

[0004] Technical solution:

[0005] The pressurized fire extinguisher of the present invention includes:

[0006] 1. High-pressure gas container: Used to store high-pressure gas and extinguishing agent, it is the main storage space of the entire pressurized fire extinguishing bottle.

[0007] 2. Divider: Located inside the bottle body, it is used to separate the high-pressure gas containment section from the bottle mouth section, and can transmit the pressure inside the container to the spring.

[0008] 3. Positioning block: Used to limit the travel of the partition.

[0009] 4. Small spring: The small spring is always in a stretched state and is used to connect the baffle and the partition.

[0010] 5. Top plate: The top plate works in conjunction with the spring and partition to support the shielding mechanism, allowing the shielding plate to flexibly adjust the size of the bottle opening.

[0011] 6. Large Spring: One end of the spring is connected to the container wall, and the other end is connected to the partition, used to adjust the position of the partition. Under high pressure, the spring is compressed, and as the pressure decreases, the spring gradually returns to its original shape, pushing the partition towards the bottle opening.

[0012] 7. Baffle plate: Connected to the top plate via a pin, it can rotate around the top plate. The baffle plate is located at the bottle mouth, and the opening area of ​​the bottle mouth can be adjusted by rotating it.

[0013] The device of the present invention is reasonably designed and has a simple structure, and can achieve a high-efficiency and stable spraying effect of a pressurized fire extinguisher. Attached Figure Description

[0015] Figure 2 This is a schematic diagram of the shielding plate. Detailed Implementation

[0016] When the gas inside the cylinder is under high pressure, the spring is compressed, and the baffle experiences greater pressure, which moves the shield to a position with a smaller opening at the cylinder mouth to control the initial spray volume. As the gas inside the cylinder is gradually released and the pressure decreases, the spring gradually returns to its natural state, and the baffle is pushed downward, causing the shield to rotate downward and increasing the opening area of ​​the cylinder mouth. This maintains the spray volume at a relatively stable level, enabling the pressurized fire extinguisher to achieve a highly efficient and stable spray effect.

Claims

1. An adaptive bottle neck structure based on a pressurized fire extinguishing bottle, characterized in that: It consists of a high-pressure gas container, a partition, a positioning block, a small spring, a top plate, a large spring, and a shielding plate. The high-pressure gas container stores high-pressure gas and extinguishing agent, and is the main storage space of the entire pressurized fire extinguishing cylinder. The partition is located inside the cylinder body and separates the high-pressure gas container from the cylinder opening, transmitting the internal pressure to the spring. The positioning block limits the travel of the partition. The small spring is always in a stretched state and connects the shielding plate and the partition. The top plate cooperates with the spring and the partition to support the shielding mechanism, allowing the shielding plate to flexibly adjust the cylinder opening size. One end of the large spring is connected to the container wall, and the other end is connected to the partition, used to adjust the position of the partition. Under high pressure, the spring is compressed, and as the pressure decreases, the spring gradually returns to its original shape, pushing the partition towards the cylinder opening. The shielding plate is connected to the top plate via a pin and can rotate around the top plate. The shielding plate is located at the cylinder opening, and its rotation adjusts the opening area.

2. The adaptive bottle neck structure based on a pressurized fire extinguishing bottle according to claim 1, characterized in that: When the gas inside the structure is under high pressure, the spring is compressed, and the partition is subjected to greater pressure, which moves the shield to a position with a smaller opening at the bottle mouth to control the initial spray volume. As the gas inside the bottle is gradually released and the pressure decreases, the spring gradually returns to its natural state, and the partition is pushed downward, causing the shield to rotate downward and increase the opening area of ​​the bottle mouth. This keeps the spray volume at a relatively stable level, enabling the pressurized fire extinguisher to achieve a highly efficient and stable spray effect.
