Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a high-pressure fine water mist foam gun. Background Technology

[0002] High-pressure fine water mist and foam extinguishing technologies have become important components of modern fire-fighting equipment due to their advantages such as high efficiency, environmental protection, and water conservation. High-pressure fine water mist atomizes water into micron-sized particles through a high-pressure pump, and utilizes its huge specific surface area to quickly absorb heat and isolate oxygen, thereby achieving rapid suppression of fire. Foam extinguishing agents, on the other hand, effectively extinguish liquid fires and solid surface fires by covering the surface of the fire source, isolating air, and having a cooling effect.

[0003] Traditional fire-fighting equipment suffers from significant inconvenience when switching between fine water mist and foam modes. It typically relies on manual disassembly or replacement of nozzles to achieve this transition. This process is not only cumbersome and time-consuming, but also fails to meet the rapid and flexible fire-fighting demands in rapidly changing emergencies. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0006] In this technical solution, two inner cavities are set on the inner side of the gun body, and are connected to a container storing foam concentrate by a one-way valve on the secondary tube. During the rotation of the drum, water can be selected to pass through either inner cavity, thereby achieving water spray or foam spray without the need for additional equipment or nozzle switching. It is convenient and quick, and realizes rapid and convenient switching between fine water mist and foam modes, which greatly improves fire extinguishing efficiency and flexibility.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0021] A high-pressure fine water mist foam gun, see Figures 1 to 3 The device includes a gun body 1, with two inner cavities 102 on its inner side. A rotating cylinder 3 is rotatably connected to the right end of the gun body 1. A sealing ring 301 is provided at the contact position between the rotating cylinder 3 and the right end of the gun body 1. The sealing ring 301 provides a seal, reducing or even preventing water leakage from the gap between the rotating cylinder 3 and the gun body 1. A water inlet cavity 302 is provided on the inner side of the rotating cylinder 3, aligned with one of the inner cavities 102. The water inlet cavity 302 is inclined and connects to both inner cavities 102 during the rotation of the rotating cylinder 3. The inner cavities 102 and the water inlet cavity 302 are connected. A secondary pipe 6 is provided at the top of the gun body 1. The upper end of the secondary pipe 6 is sealed to a one-way valve 601. The secondary pipe 6 and the one-way valve 601 are connected to a container storing foam concentrate, facilitating a continuous supply of foam. The lower end of the secondary pipe 6 is connected to the inner cavity 102, and the rotating drum 3 is connected to the water inlet pipe 303. The water inlet pipe 303 is connected to the high-pressure pump, so that the water entering can be sprayed out in the form of water mist from the fine mist nozzle 101 during flushing and squeezing. In use, the clean water entering through the water inlet pipe 303 enters one of the inner cavities 102 through the water inlet chamber 302. If it enters the lower inner cavity 102, it will be sprayed directly from the fine mist nozzle 101 to produce atomized clean water. If it enters from the upper inner cavity 102, the one-way valve 601 is opened. When the clean water passes through the inner cavity 102, the foam concentrate is drawn out from the secondary pipe 6 due to the air pressure and mixed with the clean water to produce foam spray. There is no need to switch equipment or nozzles, which is convenient and quick and improves the practicality of the device.

[0022] Specifically, such as Figure 1 and Figure 2As shown, a groove 8 is provided inside the gun body 1 at the connection point between the inner cavity 102 and the secondary tube 6. An adjusting block 9 is slidably connected to the inner side of the groove 8. An adjusting frame 7 is fixedly connected to the top of the gun body 1 above the adjusting block 9. An adjusting screw 10 passes through the outer wall of the adjusting frame 7 and is threadedly connected to the adjusting screw 10. One end of the adjusting screw 10 that passes through the adjusting frame 7 is threadedly connected to the adjusting block 9 through a bearing seat. The adjusting block 9 slides in the groove 8, and a rubber strip is provided on the outer edge of the adjusting block 9 to ensure that the gap between the groove 8 and the adjusting block 9 is sealed. When using foam spray, the screw can be rotated to drive the adjusting block 9 to move laterally along the groove 8, thereby changing the width of the connection point of the secondary tube 6 and realizing the control of the amount of foam. This improves the practicality of the device by allowing different spraying environments to be used.

[0023] Furthermore, such as Figure 3 As shown, positioning frames 2 are fixedly connected to the front and rear side walls of the gun body 1, and protrusions 4 are fixedly connected to the front and rear side walls of the rotating cylinder 3. A telescopic groove 401 is provided on the inner side of the protrusion 4, and a positioning block 5 is slidably connected to the inner side of the telescopic groove 401. A pull rod 501 is fixedly connected to one end of the positioning block 5 located inside the telescopic groove 401, and the pull rod 501 passes through the inner wall of the telescopic groove 401 and is located outside the protrusion 4. A spring 502 is sleeved on the surface of the pull rod 501 inside the telescopic groove 401. The rotating cylinder 3 passes through... The rotation is used to adjust different usage modes. When the rotation reaches the appropriate position, it needs to be kept fixed. Therefore, a positioning frame 2 is set. When the rotating drum 3 rotates, the pull rod 501 is pulled to temporarily retract the positioning block 5 into the telescopic groove 401. When it reaches the positioning frame 2, the pull rod 501 is released, and the positioning block 5 is pushed out again by the spring 502 and inserted into the positioning frame 2. At this time, the water inlet cavity 302 will be aligned with the same inner cavity 102 and remain stable to avoid deflection during water intake.

[0024] It is worth noting that, such as Figure 1 and Figure 2 As shown, a fine mist nozzle 101 is fixedly connected to the left end of the gun body 1. The surface of the fine mist nozzle 101 is provided with several small holes, so that the sprayed water mist can be dispersed. The fine mist nozzle 101 is connected to two inner cavities 102. Both inner cavities 102 are connected to the fine mist nozzle 101. When water enters one inner cavity 102, the other inner cavity 102 is closed by the shielding of the side wall of the rotating cylinder 3, and a one-way valve 601 is provided to prevent clean water from returning and entering the container storing foam concentrate.

[0025] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
