[0002] Our company has developed a nozzle with a new triggering form to reduce the force on the trigger part. The specific structure is as described in the attached instructions. Figure 1 as described above.

[0003] The triggering of this nozzle also requires designing a transition structure between the trigger module and the seal to enable the trigger module to seal the seal relative to the trigger cavity. Since the trigger module and the connection between the trigger module and the seat body are innovative applications, designing a transition structure to ensure stable force transmission between the seal and the trigger module and enabling the trigger module to trigger stably is a research direction to be explored.

[0004] Therefore, the technical problem of the prior art is: how to make the state of the nozzle stable. Summary of the Invention

[0005] The embodiments of the present application provide a nozzle, which solves the technical problem of how to make the state of the nozzle stable in the prior art and achieves the technical effect of stable state before and after the nozzle is triggered.

[0007] Preferably, the balance module includes: a balance body contacting the trigger module; a contact portion being an integral part of the balance body, the contact portion being located in the middle of the balance body and contacting the seal member; or, the contact portion being disposed in the middle of the balance body and contacting the seal member.

[0008] Preferably, the balance body is a plate body / sheet body having a deformation ability, and the balance body is in a deformed state under the action of the trigger module.

[0009] Preferably, if the contact portion and the balance body are an integral part, the contact portion protrudes outward relative to the balance body.

[0010] Preferably, the abutment portion protrudes outward with its edges converging toward the center.

[0011] Preferably, if the abutment portion is disposed in the middle of the balancing body, the abutment portion is a sphere, and a portion of the abutment portion protrudes relative to the balancing body.

[0012] Preferably, the sealing element is further provided with a water distribution tray, and the water distribution tray is located between the sealing element and the balancing module.

[0013] Preferably, the contact surface between the trigger module and the seat body is an inclined surface, and the inclined surface makes the trigger module have a tendency to retract when subjected to a component force.

[0014] Preferably, the trigger module and the seat body are threadedly connected.

[0015] Preferably, the trigger module comprises: blocks, which are provided in two groups and the two groups of blocks are arranged opposite to each other; a trigger member, which is fixedly arranged / interferingly arranged between the two groups of blocks, and the trigger member limits the inward contraction trend between the two groups of blocks.

[0017] The above one or more technical solutions in the embodiments of the present application have at least one or more of the following technical effects:

[0018] 1. The balancing module provided in the present application can stabilize the force transmission between the trigger module and the seal, ensuring that the seal is reliably sealed on the seat body when the nozzle is in the standby state; and preferably, the periphery of the balancing module contacts the trigger module and the center of the balancing module contacts the seal, so that the pressure is concentrated on the seal, making the seal work more stably, solving the technical problem of how to stabilize the state of the nozzle in the prior art; achieving the technical effect of stabilizing the state of the nozzle before and after triggering.

[0019] 2. In this application, a water-dividing tray is added between the seal and the trigger module, the original external horizontal tray structure is cancelled, and the overall height of the nozzle in the standby state is shortened, so that the nozzle of this application is suitable for concealed installation in the ceiling scene. And because the water-dividing tray will be provided with a rod body penetrating the seat body, the connection between the plate body of the water-dividing tray and the seal (the connection form can be a support member penetrating and clamping, or it can be riveted, crimped, or bonded) can limit the position of the seal; in other words, the water-dividing tray and the seal can be combined into a small assembly unit, the water-dividing tray and the seal are assembled first, and then the water-dividing tray is installed on the seat body.

[0020] 3. In this application, the balancing module can also be part of a block to reduce the number of components. Specifically, one side of the balancing module can be connected to the first block, and the other side of the balancing module can be in contact with the second block to transmit force.

[0030] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0031] A nozzle for stably responding to a fire for fire fighting. The nozzle includes a seat body 100, a sealing member 200, a triggering module 400 and a balancing module 500. The sealing member 200 is disposed in the seat body 100 to seal the water passage cavity 130 of the seat body 100. The triggering module 400 is used to abut against the sealing member 200 to ensure that the sealing member 200 is sealed. The balancing module 500 is located between the sealing member 200 and the balancing module 500. One is to stably transmit the acting force of the triggering module 400 on the sealing member 200, and the other is to cause the triggering module 400 to retract and disengage during triggering.

[0032] The seat body 100, refer to the accompanying drawings of the specification Figure 4 , the seat body 100 has a base portion 110 with a triggering cavity 120, and the triggering cavity 120 communicates with a water passage cavity 130. It can be understood that the seat body 100 has a conventional structure. The special feature is that in order for the balancing module 500 to push the triggering module 400 to retract, the contact surface of the seat body 100 relative to the triggering module 400 is set as an inclined surface, and this inclined surface converts the outward thrust of the balancing module 500 on the block 410 into a thrust towards the center of the block 410.

[0033] The sealing member 200, refer to the accompanying drawings of the specification Figure 5 , for sealing the water passage cavity 130. The sealing member 200 can be a rubber ring or a gasket. And if it is necessary to accommodate a water distribution plate 300 inside, the water distribution plate 300 can be disposed between the sealing member 200 and the balancing module 500, and the sealing member 200 and the water distribution plate 300 can be set as an integral body. Of course, the separate setting of the sealing member 200 and the water distribution plate 300 can also meet the function. Specifically, the sealing member 200 is abutted and disposed in the triggering cavity 120, and the sealing member 200 seals between the triggering cavity 120 and the water passage cavity 130.

[0034] The triggering module 400, refer to Specification 1, 3 - 4, is used to trigger when the temperature rises to a certain level to release the sealing state of the nozzle so that the nozzle can spray water for fire extinguishing. It should be particularly noted that the triggering module 400 and the seat body 100 are detachably connected (such as inclined thread connection, plugging), and the triggering module 400 acts on the seal 200. The defined direction between the triggering module 400 and the seat body 100 is the same as the acting direction of the triggering module 400 on the seal 200. However, the disassembly direction of the triggering module 400 during triggering is different from the above - defined direction and acting direction to facilitate the stable standby of the nozzle under normal conditions.

[0035] Regarding the specific structure of the triggering module 400, refer to the attached specification Figure 6 , the triggering module 400 includes a block body 410 and a triggering member 420. There are two groups of block bodies 410, and the two groups of block bodies 410 are arranged oppositely; the triggering member 420 is fixedly arranged / abuts between the two groups of block bodies 410, and the inward contraction trend between the two groups of block bodies 410 is limited by the triggering member 420.

[0036] It should be noted that the triggering concept of this nozzle is based on the component force of an inclined plane to make the two block bodies 410 in the triggering module 400 contract relatively so that the two block bodies 410 can smoothly escape from the triggering cavity 120. To implement this design, a strong triggering force is required so that the block body 410 can still be stably pushed to contract after the triggering force is decomposed. In this application, in addition to the deformation ability of the seal 200 during sealing, the set balance module 500 can also be used as a thrust source. Specifically, during assembly, the triggering module 400 is used to press the balance module 500 to make it in a deformed state. After the triggering module 400 is damaged, the balance module 500 loses the suppression, so that the balance module 500 in turn pushes the triggering module 400, and based on the inclined plane, the two groups of block bodies 410 of the triggering module 400 contract relatively to escape.

[0037] The balance module 500, refer to the attached specification Figure 1-2 , is used for force transmission and providing a rebound thrust. The balance module 500 is located between the triggering module 400 and the seal 200. The peripheral part of the balance module 500 contacts the triggering module 400, and the central part of the balance module 500 contacts the seal 200 directly / indirectly. The triggering module 400 is pressed against the seal 200 through the balance module 500.

[0038] Regarding the specific structure of the balancing module 500, the balancing module 500 includes a balancing body 520 and a resisting portion 510, the balancing body 520 contacts the trigger module 400, the resisting portion 510 and the balancing body 520 are an integral body (they can be processed by stamping, firstly, the resisting portion 510 can be quickly formed, and secondly, the structural strength of the balancing module 500 as a whole can be increased, and uniform small deformation can be ensured to avoid local excessive deformation), the resisting portion 510 is located in the middle of the balancing body 520, and the resisting portion 510 resists the sealing member 200; and if the resisting portion 510 and the balancing body 520 are an integral body, the resisting portion 510 protrudes outward relative to the balancing body 520. Alternatively, the resisting portion 510 is arranged in the middle of the balancing body 520, and the resisting portion 510 resists the sealing member 200; and if the resisting portion 510 is arranged in the middle of the balancing body 520, the resisting portion 510 is a sphere, and part of the resisting portion 510 protrudes relative to the balancing body 520. It can be understood that the balancing body 520 is a plate / sheet body with deformation ability, and the balancing body 520 is in a deformed state under the action of the trigger module 400; and the style of the resistance part 510 can be a protrusion with the edge converging toward the center. Preferably, the tip of the resistance part 510 is a round head to better bear the force and avoid scratches caused by the rotation of the seal 200 relative to the seat body 100 when the trigger module 400 is screwed in.

[0039] In one embodiment, the balancing module 500 is a part of at least one of the two groups of blocks 410 (not shown in the drawings), and the balancing module 500 is connected to at least one group of blocks 410 .

[0040] Working principle:

[0041] Reference Manual Attached Figure 3-4 During assembly, the trigger module 400 is used to apply pressure to the balancing module 500 to put it in a deformed state. After the trigger module 400 is destroyed, the balancing module 500 loses its pressure, so that the balancing module 500 in turn pushes the trigger module 400, and based on the inclined contact surface between the trigger module 400 and the seat body 100, the two groups of blocks 410 of the trigger module 400 are relatively retracted to come out.

[0042] Technical effect:

[0043] 1. The balancing module 500 provided in the present application can stabilize the force transmission between the trigger module 400 and the seal 200, and ensure that the seal 200 is reliably sealed on the seat body 100 when the nozzle is in the standby state; and preferably, the periphery of the balancing module 500 contacts the trigger module 400 and the center of the balancing module 500 contacts the seal 200, so that the pressure is concentrated on the seal 200, so that the seal 200 works more stably, and solves the technical problem of how to stabilize the state of the nozzle in the prior art; and achieves the technical effect of stabilizing the state of the nozzle before and after triggering.

[0044] 2. In the present application, a water separating plate 300 is added between the seal 200 and the trigger module 400, and the original external horizontal plate structure is cancelled, shortening the overall height of the nozzle in the standby state, so that the nozzle of the present application is adapted to the concealed installation in the ceiling scenario. And because the water separating plate 300 is provided with a rod body 320 passing through the seat body 100, the connection between the plate body 310 of the water separating plate 300 and the seal 200 (the connection form can be that the support member passes through and is clamped, or riveting, pressing, or bonding) can limit the position of the seal 200; in other words, the water separating plate 300 and the seal 200 can be combined into a small assembly unit, the water separating plate 300 and the seal 200 are assembled first, and then the water separating plate 300 is installed on the seat body 100.

[0045] 3. In the present application, the balance module 500 can also be a part of the block body 410 to reduce the number of parts; specifically, one side of the balance module 500 can be connected to the first block body 410a, and the other side of the balance module 500 can contact and transmit force to the second block body 410b.
