[0024] Hereinafter, embodiments will be described with reference to the accompanying drawings, which do not limit the disclosure described in the claims in any way.

[0025] See also Figure 1 to Figure 3 , the following combination Figure 1 to Figure 3 An atomizing nozzle device provided in an embodiment of the present application is described in detail.

[0026] The present application embodiment provides an atomizing nozzle device, which is applied to the technical field of battery fire extinguishing equipment. For details, please refer to Figure 1 to Figure 3 The atomizing nozzle device includes a nozzle body 1, a sealing assembly 2 and an atomizing element 3.

[0027] Among them, the sealing assembly 2 and the atomizer 3 are arranged in sequence in the accommodating space of the nozzle body 1, the atomizer 3 is arranged at one end close to the nozzle head 11 in the nozzle body 1, the sealing assembly 2 includes a sealing member 21 and a clamping member 22, and the nozzle body 1 is provided with a nozzle hole 12 at one end away from the nozzle head 11. The sealing member 21 and the clamping member 22 are arranged on the nozzle hole 12 in sequence, and the clamping member 22 is located on the side of the sealing member 21 away from the nozzle hole 12. The clamping member 22 has an interference fit or a clearance fit with the inner side wall of the nozzle body 1.

[0028] In the embodiment of the present application, the sealing assembly 2 is used to seal the nozzle hole 12 to prevent external water vapor or dust from entering the battery fire extinguishing device through the nozzle hole 12, thereby damaging the solenoid valve and other devices in the battery fire extinguishing device. Specifically, the sealing assembly 2 includes a sealing member 21 and a pressing member 22 which are sequentially arranged on the nozzle hole 12, and the pressing member 22 is located on the side of the sealing member 21 away from the nozzle hole 12, so that the nozzle hole 12 can be sealed by the sealing member 21, and the sealing member 21 is fastened to the nozzle hole 12 by the pressing member 22, thereby achieving waterproof sealing of the atomizing nozzle device.

[0029] In a specific embodiment, the pressing piece 22 is interference fit or clearance fit with the inner side wall of the nozzle body 1 so that the sealing member 21 can be fastened by the pressing piece 22. At the same time, due to the interference fit or clearance fit between the pressing piece 22 and the inner side wall of the nozzle body 1, during the process of fastening the sealing member 21, the pressing piece 22 only applies a pressing force to the sealing member 21, and does not apply a rotational twisting force to the sealing member 21, thereby avoiding the sealing member 21 from twisting, deformation, or rupture during the assembly process, thereby improving the qualified rate of the atomizing nozzle device and reducing the production cost.

[0030] It should be noted that if the clamping piece 22 has an interference fit with the inner wall of the nozzle body 1, the outer wall of the clamping piece 22 is a smooth curved surface, so as to utilize the smooth curved surface of the clamping piece 22 to have an interference fit with the inner wall of the nozzle body 1; if the clamping piece 22 has a clearance fit with the inner wall of the nozzle body 1, the outer wall of the clamping piece 22 can be a smooth curved surface, a spiral curved surface, or an uneven curved surface. Therefore, in the scenario where the clamping piece 22 has a clearance fit with the inner wall of the nozzle body 1, there is no specific limitation on the state of the outer wall of the clamping piece 22.

[0031] In a specific embodiment, the sealing member 21 may be a sheet-like structure, the material of the sealing member 21 is rubber, and the area of ​​the sealing member 21 in the sheet-like structure is larger than the area of ​​the nozzle hole 12 .

[0032] Specifically, the embodiment of the present application sets the seal 21 as a sheet structure so that the seal 21 fits the nozzle body 1, which helps to seal. At the same time, the material of the seal 21 is set to rubber material to ensure the waterproof and dust-proof sealing effect of the atomizing nozzle device. Furthermore, by setting the area of ​​the seal 21 with a sheet structure to be larger than the area of ​​the nozzle hole 12, incomplete sealing of the seal 21 to the nozzle hole 12 is avoided, which causes water vapor or dust to enter the battery fire extinguishing equipment through the atomizing nozzle device, and has a good sealing effect.

[0033] In practical applications, the sealing member 21 may be a rubber diaphragm, wherein the size of the rubber diaphragm is equal to the caliber of the connection and fastening hole 13 in the nozzle body 1 .

[0034] In some embodiments, the shape of the seal 21 can be circular, rectangular, triangular or diamond-shaped, etc. Figure 2 As shown, the sealing member 21 is circular in shape.

[0035] In an optional embodiment, if Figure 1 and Figure 2 As shown, a connection fastening hole 13 is provided at one end of the nozzle body 1 away from the nozzle head 11 , and the connection fastening hole 13 is interference-fitted with the outer side wall of the pressing member 22 .

[0036] In the embodiment of the present application, the outer wall of the clamping piece 22 is a smooth curved surface, and a connecting fastening hole 13 is provided at the end of the nozzle body 1 away from the nozzle head 11 so that the connecting fastening hole 13 and the smooth curved surface of the clamping piece 22 are interference fit. When the connecting fastening hole 13 and the outer wall of the clamping piece 22 are fitted and connected, the clamping piece 22 only applies a pressing force to the seal 21 to slide toward the seal 21, and does not apply a rotational twisting force to the seal 21, thereby avoiding the seal 21 from twisting, deformation and rupture during the assembly process, thereby improving the performance of the atomizing nozzle device.

[0037] In a specific embodiment, Figure 1 and Figure 2 As shown, the diameter of the connection fastening hole 13 is larger than the diameter of the nozzle hole 12 .

[0038] In the embodiment of the present application, the diameter of the connecting and fastening hole 13 is set to be larger than the diameter of the nozzle hole 12 so that the clamping piece 22 can be set in the connecting and fastening hole 13, and the clamping piece 22 can be placed on the nozzle body 1 outside the nozzle hole 12, so that during the interference fit between the outer wall of the clamping piece 22 and the connecting and fastening hole 13 in the nozzle body 1, the nozzle body 1 applies a force opposite to the clamping force to the sealing piece 21, thereby achieving the fastening of the sealing piece 21 by the clamping piece 22 without covering the nozzle hole 12.

[0039] In an optional embodiment, the sealing assembly 2 further includes a connecting fastener, and the pressing member 22 is fixedly connected to the inner side wall of the nozzle body 1 via the connecting fastener.

[0040] Specifically, in a scenario where the clamping piece 22 and the inner wall of the nozzle body 1 are gap-matched, a connecting fastener needs to be provided so that the clamping piece 22 is fixedly connected to the inner wall of the nozzle body 1 through the connecting fastener. When the clamping piece 22 is fixedly connected to the inner wall of the nozzle body 1 through the connecting fastener, the clamping piece 22 moves toward the direction approaching the sealing piece 21 until the side of the clamping piece 22 close to the sealing piece 21 abuts against the sealing piece 21, and the sealing piece 21 can be fastened by the clamping piece 22.

[0041] It should be noted that when the clamping piece 22 is fixedly connected to the inner wall of the nozzle body 1 through the connecting fastener, the connecting fastening hole 13 in the nozzle body 1 and the outer wall of the clamping piece 22 can also be an interference fit, so as to enhance the fastening degree between the nozzle body 1 and the clamping piece 22 and ensure the reliability and stability of the atomizing nozzle device.

[0042] In practical applications, the connecting fasteners may be rivets or connecting pins, etc.

[0043] In an optional embodiment, the connection between the pressing member 22 and the nozzle body 1 is by riveting or spinning.

[0044] In the embodiment of the present application, the clamping member 22 is connected to the nozzle body 1 by riveting or spinning to enhance the fastening effect. In practical applications, riveting, also known as riveting, is a mechanical connection method that uses rivets to connect two or more workpieces, wherein the riveting process generally includes steps such as pretreatment, drilling, rivet installation, rotation and extrusion. Spinning is a connection process that fixes the rivet on the workpiece by rotation and extrusion.

[0045] In an optional embodiment, if Figure 1 and Figure 2 As shown, the atomizing nozzle device further includes a filter element 4 , which is disposed in the accommodating space and located between the pressing element 22 and the atomizing element 3 , and is fixedly connected to the inner side wall of the nozzle body 1 .

[0046] In the embodiment of the present application, by providing the filter element 4, on the one hand, it is possible to avoid the situation where large particles of impurities inside the atomizing nozzle device clog the nozzle head 11. On the other hand, it also reduces the risk of clogging the nozzle head 11 by debris generated when the seal 21 breaks, thereby improving the stability and reliability of the atomizing nozzle device.

[0047] It should be noted that during the use of the atomizing nozzle device, a pressure exceeding the maximum pressure that the seal 21 can withstand needs to be applied to the seal 21 in order to break the seal 21, so that the fluid medium can pass through the atomizing element 3 to produce an atomization effect and be sprayed out through the nozzle head 11 to perform operations such as fire extinguishing.

[0048] In an optional embodiment, the filter element 4 may be a mesh structure, and the filter element 4 may be made of stainless steel.

[0049] In the embodiment of the present application, the filter element 4 can be a stainless steel filter mesh. Furthermore, by arranging the stainless steel filter mesh between the clamping element 22 and the atomizing element 3, the stainless steel filter mesh can be used to reduce the risk of clogging the nozzle head 11 by large particles of impurities inside the atomizing nozzle device or debris generated when the seal 21 is broken.

[0050] In practical applications, the shape of the filter element 4 can be rectangular, triangular or circular, etc. Preferably, Figure 2 As shown, the filter element 4 is circular in shape.

[0051] It should be noted that there may be a connecting protrusion at the edge of the circular filter element 4, so that the filter element 4 can be fixedly connected to the inner wall of the nozzle body 1 by using the connecting protrusion. In some embodiments, the connection method between the connecting protrusion and the inner wall of the nozzle body 1 can be clamping, welding or bonding.

[0052] In an optional embodiment, if Figure 2 As shown, the pressing member 22 is a cylindrical structure, and the cylindrical pressing member 22 includes a cylindrical hole 221 , which extends along the axial direction of the pressing member 22 and penetrates the pressing member 22 , and the diameter of the cylindrical hole 221 is equal to the diameter of the nozzle hole 12 .

[0053] In the embodiment of the present application, a cylindrical hole 221 extending along the axial direction of the pressing piece 22 and penetrating the pressing piece 22 is provided in the pressing piece 22, and the diameter of the cylindrical hole 221 is set to be equal to the diameter of the nozzle hole 12, so that while the sealing piece 21 is tightened, the pressing piece 22 can be prevented from covering the nozzle hole 12 to hinder the flow of the fluid medium.

[0054] In an optional embodiment, the atomizing element 3 includes a swirl plate, the output port of the swirl plate faces the nozzle head 11, and the swirl plate is used to atomize the fluid medium.

[0055] In the embodiment of the present application, an atomizing element 3 including a vortex sheet is provided so as to utilize the vortex sheet to perform atomization processing on the fluid medium.

[0056] It should be noted that the vortex sheet is a device used for atomization. When the fluid medium passes through the vortex sheet, a vortex will be generated. The vortex generated by the vortex sheet can drive small particles or droplets in the fluid medium to rotate. Due to the action of centrifugal force, these small particles or droplets will be separated from the vortex, forming an atomization effect. Among them, the vortex is a rotating airflow, which can drive the surrounding fluid medium to rotate together to form a vortex. The vortex can change the flow direction and properties of the fluid medium, making the fluid medium easier to be atomized, thereby achieving an atomization effect.

[0057] In some embodiments, the output port of the swirl sheet is arranged toward the nozzle head 11 so that the fluid medium with atomization effect is sprayed out from the nozzle head 11, which helps to improve the spraying efficiency and spraying effect.

[0058] In some specific embodiments, Figure 1 and Figure 2As shown, the atomizing nozzle device may further include a sealing ring 5, wherein the sealing ring 5 is disposed in the accommodating space and between the atomizing element 3 and the nozzle head 11. Furthermore, by arranging the sealing ring 5, the sealing ring 5 can be utilized to enhance the sealing effect between the atomizing element 3 and the nozzle head 11.

[0059] Combine the following Figure 1 to Figure 3 , introduces the specific working principle of an atomizing nozzle device provided in an embodiment of the present application.

[0060] Specifically, when there is a pressurized fluid medium contacting the seal 21 from the outside, when the pressure is lower than the preset pressure threshold, that is, when there is water vapor outside with an impact force less than the preset pressure threshold, the water vapor existing outside will be blocked outside the seal 21, thereby meeting the sealing and waterproof requirements under different working conditions. When there is a pressurized fluid medium contacting the seal 21 from the inside, when the pressure exceeds the preset pressure threshold, that is, when the fluid medium needs to be sprayed using an atomizing nozzle device, wherein the fluid medium is water, the applied pressure can cause the seal 21 to rupture, and then the fluid medium inside the atomizing nozzle device can flow to the filter 4 through the cylindrical hole 221 in the clamping member 22. At this time, the filter 4 can prevent the ruptured seal 21 from blocking the nozzle head 11, so that the medium fluid filtered out of the ruptured seal 21 can reach the vortex sheet, and use the vortex sheet to produce an atomization effect, and finally spray out from the nozzle head 11, so as to achieve the purpose of atomizing water spraying using the atomizing nozzle device.

[0061] The above embodiments of the present application have the following beneficial effects:

[0062] The present application arranges the sealing member and the pressing member in sequence on the nozzle hole in the nozzle body, and makes an interference fit or a clearance fit between the pressing member and the inner wall of the nozzle body, so that the sealing member can be fastened by the pressing member while avoiding the sealing member from twisting, deforming and breaking during the assembly process, thereby improving the qualified rate of the atomizing nozzle device and reducing the production cost.
