[0028] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] See also Figure 1-Figure 5 A perfluorohexanone rapid diffuser comprises a storage tank 1 for storing a perfluorohexanone solution, a container valve 2 is fixedly mounted on the top surface of the storage tank 1 and a manual valve 3 is mounted on the top of the container valve 2, the storage tank 1 comprises a perfluorohexanone solution layer 11 for storing the perfluorohexanone solution and a nitrogen layer 12 for filling nitrogen which are sequentially connected from bottom to top, a straw 13 extending to the bottom of the storage tank 1 is arranged at the center of the storage tank 1, an interface 23 is arranged on the side wall of the container valve 2, the inner end of the interface 23 is connected to the water outlet of the manual valve 3 and the outer end is threadedly connected to a high-pressure hose 4, the other end of the high-pressure hose 4 is threadedly connected to a rapid diffusion device 5, the rapid diffusion device 5 comprises a connecting tube 51 connected to the high-pressure hose 4 and a plurality of extension branches 52 for rapidly diffusing the perfluorohexanone gas, a plurality of extension branches 52 are each provided with a plurality of nozzles 53, the nozzles 53 face in a direction away from the high-pressure hose 4, and an electric fan 6 for promoting the diffusion of the perfluorohexanone gas is installed at the center of one end face of the rapid diffusion device 5 away from the high-pressure hose 4.

[0031] Specifically, the container valve 2 is connected to the interior of the storage tank 1, and a pressure gauge 21 for detecting the internal pressure value of the container valve 2 is provided on the outer wall of the container valve 2. A pressure relief port 22 for releasing pressure when the pressure value is too large is also provided on the outer wall of the container valve 2. Through the display of the pressure gauge 21, the safety hazard of explosion caused by excessive pressure inside the storage tank 1 is avoided. When the pressure value reaches a limited value, the pressure is discharged through the pressure relief port 22, thereby improving the safety of the device.

[0032] Specifically, a manual air pressure pump 14 for increasing the internal air pressure of the storage tank 1 is installed at the connection between the container valve 2 and the storage tank 1. The manual air pressure pump 14 is used to pressurize the interior of the storage tank 1. The manual air pressure pump 14 uses a piston method to pressurize. The external air is pressed into the storage tank 1 through the manual air pressure pump 14, so that the perfluorohexanone solution is squeezed from the straw 13 to the manual valve 3 through the internal high air pressure. When the manual valve 3 is opened, the perfluorohexanone solution is sprayed directly from the nozzle 53 along the high-pressure hose 4.

[0033] Specifically, the high-pressure hose 4 is made of soft rubber material, and threaded caps are provided at the joints at both ends of the high-pressure hose 4 for threaded connection with the interface 23 and the connecting tube 51 respectively. The end of the high-pressure hose 4 close to the interface 23 is trumpet-shaped, so that when the perfluorohexanone solution enters the trumpet-shaped port of the high-pressure hose 4, the channel opening becomes smaller, so that the pressure inside the high-pressure hose 4 becomes higher, which is more convenient for the perfluorohexanone solution to be quickly vaporized into a gas state; the two ends of the high-pressure hose 4 are threadedly connected by threaded caps to avoid water leakage and pressure relief when the interface is used for too long, thereby causing the nozzle 53 to fail to achieve the power of injection, causing the device to fail.

[0034] Specifically, a plurality of extension branch pipes 52 are radially distributed on the outer side of the arc of the connecting tube 51, one end of the extension branch pipe 52 is connected to the connecting tube 51 and the other end is closed, and a plurality of nozzles 53 on each extension branch pipe 52 are distributed at equal intervals, and the size of the nozzle 53 is 0.5-0.8 mm, which increases the pressure at the nozzle 53, so that the perfluorohexanone can be sprayed farther during the spraying process and achieve faster diffusion.

[0035] Specifically, the electric fan 6 includes an overall cylindrical shell and a plurality of vents 60 opened on the side wall of the shell. The electric fan 6 includes a motor 61 installed inside the shell, a rotating shaft 62 coaxially fixedly connected to the output shaft of the motor 61, and a plurality of fan blades 63 are installed on the rotating shaft 62. The rotation of the rotating shaft 62 drives the fan blades 63 to rotate, thereby forming wind force and achieving a rapid diffusion effect.

[0036] Specifically, the number of fan blades 63 is at least two and several fan blades 63 are distributed in a circle with equal intervals. The length of the fan blade 63 is smaller than the inner radius of the outer casing of the electric fan 6. The fan blade 63 is made of aluminum alloy. The outer casing of the electric fan 6 is equipped with a protective net 64 at the port close to the fan blade 63 to prevent the fan blade 63 from rotating and directly hitting the human body during use, thereby causing a safety hazard.

[0037] Specifically, a battery for powering the motor 61 is installed inside the electric blower 6. The battery is detachably installed in the housing of the electric blower 6 and does not contact the motor 61, so that the device can be carried and moved, thereby achieving a better fire extinguishing effect.

[0038] Finally, it should be noted that the manual air pressure pump 14, container valve 2, manual valve 3, motor 61 and other components involved in the utility model are all universal standard parts or components known to technical personnel in this field, and their structures and principles are all known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0039] Working principle: The device has two specific working modes: one is to release perfluorohexanone, and the other is to close the release of perfluorohexanone:

[0040] Release perfluorohexanone. Under the pressure of the nitrogen layer 12, perfluorohexanone is squeezed from the suction tube 13, passes through the container valve 2 and reaches the inside of the manual valve 3. When the manual valve 3 is opened, the perfluorohexanone is connected from the interface 23 and enters the inside of the high-pressure hose 4, and is sprayed out through the nozzle 53 on the extension branch 52 provided on the rapid diffusion device 5. At the same time, the electric fan 6 is started to form wind force, thereby accelerating the diffusion of perfluorohexanone and expanding its diffusion range. At the same time, when the internal pressure of the storage tank 1 is insufficient, external air can be pressed into it through the manual air pressure pump 14, so that the internal pressure of the storage tank 1 is always maintained at a high pressure state, so that the perfluorohexanone is continuously sprayed out to ensure the effect of fire extinguishing.

[0041] Close and release perfluorohexanone. When the release is completed, the manual valve 3 is closed, and perfluorohexanone no longer passes through the manual valve 3. No perfluorohexanone is sprayed out from the rapid diffusion device 5. At this time, the electric fan 6 is closed to complete the closing operation.

[0042] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) to form a technical solution.
