[0001] This application relates to the field of fire safety technology, specifically to a water mist nozzle for fire extinguishing. Background Technology

[0002] In modern buildings, sprinklers are usually installed indoors to reduce the probability of indoor fires. In the event of a fire, water mist is sprayed from the sprinklers to extinguish the fire.

[0003] Currently, the spray area of ​​the sprinkler head is constant under a certain water pressure. If users want to adjust the spray area of ​​the sprinkler head, they can only adjust the water pressure. This requires corresponding modifications to the water supply equipment or replacement of the sprinkler head, both of which have the drawback of high cost. Utility Model Content

[0004] This application provides a water mist nozzle for fire extinguishing, which can effectively solve the above-mentioned problems.

[0005] The specific technical solution of this embodiment is as follows:

[0006] This application provides a water mist nozzle for fire extinguishing, including a body and an adjusting member. The body has an internal receiving space and an inlet communicating with the receiving space. The body also has several through holes, at least a portion of which communicate with the receiving space. The adjusting member is at least partially located in the receiving space and is movably connected to the body, allowing it to move relative to the body. The adjusting member is configured to block different numbers of through holes during movement, preventing the blocked through holes from communicating with the receiving space.

[0007] In some embodiments, the adjusting member includes a partition configured to be movable relative to the body, the partition dividing the interior of the body into a receiving space and an adjusting space, and the partition blocking a portion of the through-holes communicating with the adjusting space.

[0008] In some embodiments, the body has an opening, and the adjusting member includes an interconnected partition and an adjusting portion, a portion of which is located in the adjusting space, and another portion of which extends out of the adjusting space through the opening.

[0009] In some embodiments, the adjustment part is threadedly connected to or damped by the body.

[0010] In some embodiments, the receiving space is oriented toward the adjustment space along a first direction, and the size of the through hole gradually increases along the first direction.

[0011] In some of these embodiments, the through-holes are all the same size.

[0012] In some embodiments, the body has an opening, the adjusting member is a hollow structure with an opening on one side, the adjusting member and the body form a sleeve structure, the adjusting member includes a side wall and a bottom wall, the side wall is located in the receiving space, and a channel is provided on the side wall so that a portion of the through hole connects to the receiving space through the channel.

[0013] In some embodiments, the sidewall includes a first region and a second region, with the first region located between the entrance and the second region along the direction of gravity, and the second region located below the entrance, with the passage located in the second region.

[0014] In some embodiments, the adjustment element is connected via sidewall damping.

[0015] Compared with the prior art, the embodiments of this application have the following beneficial effects:

[0016] The water mist nozzle for fire extinguishing provided in this application embodiment adjusts the number of through holes connected to the containment space by moving the adjusting member relative to the main body. Under constant water pressure, the inner through holes are used to discharge water from the containment space. Therefore, when the number of through holes connected to the containment space is small, the amount of water flowing into the containment space remains constant, while the amount of water discharged decreases. As a result, a greater water pressure can be generated in the containment space, thereby making the spray area of ​​the water mist flowing out through the through holes connected to the containment space larger.

[0028] This application provides a water mist nozzle for fire extinguishing; please refer to [link / reference]. Figure 1 and Figure 2 The system includes a body 10 and an adjusting member 20. The body 10 has an internal receiving space and an entrance 101 communicating with the receiving space. The body 10 also has a plurality of through holes 102, at least a portion of which communicate with the receiving space. The adjusting member 20 is at least partially located in the receiving space and is movably connected to the body 10, allowing the adjusting member 20 to move relative to the body 10. The adjusting member 20 is configured to block a different number of through holes 102 during movement, preventing the blocked through holes 102 from communicating with the receiving space.

[0029] The containment space refers to at least a portion of the space inside the main body 10. The inlet 101 is used to connect to the water inlet pipe, through which water flows into the containment space.

[0030] The adjusting member 20 will block a different number of through holes 102 depending on its location. The number of through holes 102 blocked is determined at any specific location.

[0031] In the above embodiment, by moving the adjusting member 20 relative to the body 10, the number of through holes 102 communicating with the receiving space is adjusted. Under constant water pressure, the inner through holes 102 are used to discharge water from the receiving space. Therefore, when the number of through holes 102 communicating with the receiving space is small, the amount of water flowing into the receiving space remains constant, while the amount of water discharged decreases. This results in a greater water pressure being generated within the receiving space, thereby increasing the spray area of ​​the water mist flowing out through the through holes 102 communicating with the receiving space. In specific application scenarios, the adjusting member 20 can be adjusted according to the different spray area requirements at different times to obtain water mist nozzles with different spray ranges, without needing to adjust the inlet water pressure or replace the nozzles. Therefore, the cost is lower and the applicability is wider. On the other hand, when the water pressure of the incoming water is unstable, it can also be adjusted by the adjusting component 20 to keep the water pressure in the containment space constant. For example, when the water pressure of the incoming water is low, the adjusting component 20 can block more of the through holes 102 to maintain the water pressure in the containment space, thereby ensuring that the required spraying range can be obtained under different water pressures.

[0032] In some embodiments, the adjusting member 20 includes a partition 201 configured to be movable relative to the body 10, the partition 201 dividing the interior of the body 10 into a receiving space and an adjusting space, and the partition 201 blocking a portion of the through-hole 102 communicating with the adjusting space.

[0033] The adjusting member 20 may include only the partition 201, or it may include both the partition 201 and the adjusting part 202. When the adjusting member 20 includes only the partition 201, the partition 201 is movably connected to the body 10. The relative movement between the partition 201 and the body 10 can be achieved by electromagnetic control. Alternatively, the partition 201 may be moved by extending a portion to the outside of the body 10 and then adjusting the portion inside the body 10 accordingly.

[0034] The partition 201 divides the interior of the main body 10 into a receiving space and an adjusting space. As the partition 201 moves relative to the main body 10, the size ratio of the receiving space and the adjusting space changes accordingly. In a specific example, when the partition 201 is moved, causing the receiving space to gradually decrease and the adjusting space to gradually increase, the number of through holes 102 connected to the receiving space also gradually decreases. With the same inlet water pressure, the pressure within the receiving space gradually increases, resulting in a larger spray area for the water flowing out through the through holes 102. The through holes 102 connected to the adjusting space are blocked. Because these blocked through holes 102 cannot connect to the receiving space, water introduced into the receiving space through the inlet 101 cannot flow out through these blocked through holes 102.

[0035] In the above embodiment, by setting a partition 201 that is movable relative to the main body 10, the size ratio of the internal storage space and the adjustment space of the main body 10 is adjusted, thereby adjusting the number of blocked through holes 102. By adjusting the size of the storage space and the number of blocked through holes 102, the spraying area of ​​the water mist nozzle is adjusted.

[0036] In some embodiments, the body 10 has an opening 203, and the adjustment member 20 includes a partition 201 and an adjustment portion 202 connected to each other, with a portion of the adjustment portion 202 located in the adjustment space and another portion of the adjustment portion 202 extending out of the adjustment space through the opening 203.

[0037] In the above embodiment, by setting the adjusting member 20 to include a partition 201 and an adjusting part 202, the partition 201 is used to adjust the number of through holes 102 blocked, the adjusting part 202 is used to adjust the movement of the partition 201, and the adjusting part 202 extends out of the adjusting space through the opening 203 of the body 10, so as to facilitate the adjustment of the movement of the partition 201 by the adjusting part 202, making the operation more convenient.

[0038] In some embodiments, the adjustment part 202 is threaded or damped to the body 10.

[0039] In the above embodiment, when the adjusting part 202 is threadedly connected to the body 10, an external thread can be provided on the outside of the adjusting part 202 and an internal thread can be provided on the inside of the body 10. The external thread and the internal thread cooperate with each other to change the size of the adjusting part 202 extending into the body 10, thereby adjusting the position of the partition 201.

[0040] When the adjustment part 202 is damped and connected to the body 10, the adjustment part 202 and the inner wall of the body 10 are fixed by friction. Only when the force exceeds a certain level can the adjustment part 202 and the body 10 move relative to each other. In a specific example, the force that enables the adjustment part 202 and the body 10 to move relative to each other needs to be greater than the maximum force that the water pressure in the containment space can provide.

[0041] In some embodiments, the receiving space is oriented toward the adjustment space along a first direction, and the size of the through hole 102 gradually increases along the first direction.

[0042] In the above embodiment, the first direction is a single direction from the accommodating space to the adjusting space. Along the first direction, the size of the through hole 102 gradually increases. When the partition 201 divides the interior of the body 10 into the accommodating space and the adjusting space, when the partition 201 moves toward the accommodating space, the accommodating space gradually decreases. Under the condition of a certain water pressure, the water pressure in the accommodating space gradually increases, thereby making the spraying range of the nozzle wider. When the partition 201 moves toward the accommodating space, the large-sized through hole 102 is preferentially blocked, and the remaining through holes 102 communicating with the accommodating space are relatively small through holes 102. At this time, the part of the through holes 102 that are connected to the accommodating space as water outlets are smaller in size, thereby further increasing the water pressure in the accommodating space, thereby further increasing the spraying range of the nozzle.

[0043] In some embodiments, the through-hole 102 has the same size.

[0044] In this embodiment, the through holes 102 are all the same size. At this time, the spray range of the nozzle can only be adjusted by the number of through holes 102 blocked by the adjusting member 20. When set up, the through holes 102 on the body 10 are all the same size, which reduces the manufacturing cost of the body 10 and makes it easier to manufacture.

[0045] In some of these embodiments, please refer to further details. Figure 3 The main body 10 has an opening 203. The adjusting member 20 is a hollow structure with an opening 203 on one side. The adjusting member 20 and the main body 10 form a sleeve structure. The adjusting member 20 includes a side wall 204 and a bottom wall. The side wall 204 is located in the receiving space. The side wall 204 is provided with a channel 205 so that part of the through hole 102 is connected to the receiving space through the channel 205.

[0046] In the above embodiments, with Figure 2 and Figure 3 For example, in Figure 2 In the middle, the side of the adjusting component 20 closest to the main body 10 is a plate structure, which is related to... Figure 2 The difference is that, in Figure 3 In the middle, the adjusting member 20 has a hollow structure and an opening 203 on the side of the adjusting member 20 near the body 10. The adjusting member 20 and the body 10 form a sleeve structure so that the side wall 204 of the adjusting member 20 and the side wall 204 of the body 10 together form a receiving space. At this time, the side wall 204 of the adjusting member 20 can block part of the through hole 102 on the body 10 to adjust the spraying area of ​​the nozzle. The side wall 204 of the adjusting member 20 is provided with a channel 205. The water in the receiving space first passes through the channel 205 on the side wall 204, and then is sprayed through the through hole 102 that communicates with the channel 205 on the side wall 204.

[0047] In some embodiments, the sidewall 204 includes a first region and a second region, with the first region located between the inlet 101 and the second region along the direction of gravity, and the second region located below the inlet 101, and the channel 205 located in the second region.

[0048] In the above embodiment, the sidewall 204 has a first region and a second region respectively from top to bottom along the direction of gravity. It can be considered that the first region and the second region are respectively parts of the sidewall 204. Figure 3 As shown, the area of ​​the side wall 204 located above the middle can be considered as the first area, and the area of ​​the side wall 204 located below the middle can be considered as the second area. The channel 205 is located in the second area, which allows the area of ​​the side wall 204 of the adjusting member 20 above the gravity direction to block the through hole 102 on the body 10. This allows water in the containing space to flow out from below the gravity direction through the channel 205 and then out of the through hole 102. This arrangement can reduce the amount of water remaining in the containing space, thereby reducing the impact of water on the water mist nozzle, such as the impact of weight or corrosion.

[0049] In some embodiments, the adjusting member 20 is damped by a sidewall 204. This configuration allows the adjusting member 20 to be movably connected to the body 10, thereby enabling adjustment of the spray area of ​​the nozzle.

[0050] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
