[0031] It can be understood that the splashback 20 in the embodiment is installed at the spray head 100, and the water flow sprayed by the spray head 100 impacts on the splashback 20, and then is sprayed to the periphery of the splashback 20 through the grooves 22. The splashback 20 increases the spraying range, so that the watering is more uniform, and better fire extinguishing effect is achieved.

[0032] Specifically, in the embodiment, the main disc 21 is a disc. The number of the connecting holes 23 is two. The connecting holes 23 are arranged at opposite sides of the main disc 21 respectively. The center line of the two connecting holes 23 coincides with the diameter of the main disc 21. It can be understood that the splashback 20 in the embodiment is detachably connected with the spray head 100 through the connecting holes 23. Specifically, the splashback 20 can be fixed on the spray head 100 through bolts and the like. After the thermal sensitive assembly 30 of the spray head 100 is removed for fire extinguishing once, the splashback 20 can be easily removed and the new thermal sensitive assembly 30 is installed.

[0033] It can be easily understood that the connecting holes 23 are symmetrically arranged on the main disc 21 in the embodiment, so that the force of the splashback 20 is uniform. When the splashback 20 is impacted by the water flow, the splashback 20 can be kept perpendicular to the water spraying direction of the spray head 100, and uniform watering is maintained.

[0034] Further, the recesses 22 include first recesses 221. The first recesses 221 are arranged on the side of the connecting holes 23. Specifically, in the embodiment, the number of the first recesses 221 is four, and two first recesses 221 are arranged on each side of the connecting holes 23 of the main body disc 21. The connecting holes 23 are arranged between the two first recesses 221. In order to make the structure of the connecting holes 23 stable, the extension direction of the first recesses 221 is parallel to the line connecting the connecting holes 23 to the central position of the main body disc 21. It can be understood that the extension direction of the first recesses 221 is parallel to the radial direction in which the connecting holes 23 are arranged, so as to keep the material width of the main body disc 21 at the position where the connecting holes 23 are arranged consistent, and improve the connecting strength of the connecting holes 23. In addition, the first recesses 221 can also ensure the water spraying amount on both sides of the main body disc 21.

[0035] Further, the recesses 22 also include second recesses 222. The second recesses 222 are arranged at intervals along the edge of the main body disc 21. The extension direction of the second recesses 222 is towards the central position of the main body disc 21. It can be understood that the first recesses 221 are used for spraying water to both sides of the splashback disc 20. The second recesses 222 are used for spraying water to the periphery of the splashback disc 20. Specifically, in the embodiment, the first recesses 221 and the second recesses 222 are arranged at intervals, which is beneficial to make the water spraying of the splashback disc 20 more uniform, and improve the fire extinguishing effect.

[0036] Specifically, the second recesses 222 include long grooves 2221 and short grooves 2222. The long grooves 2221 are arranged away from the connecting holes 23. The short grooves 2222 are arranged close to the connecting holes 23. In the embodiment, the number of the long grooves 2221 and the short grooves 2222 is four. The long grooves 2221 and the short grooves 2222 are symmetrically arranged along the line connecting the connecting holes 23, that is, two long grooves 2221 and two short grooves 2222 are arranged on one side of the line connecting the connecting holes 23, and two long grooves 2221 and two short grooves 2222 are arranged on the other side of the line connecting the connecting holes 23. On one side of the line connecting the connecting holes 23, from the connecting hole 23 to the other connecting hole 23, the edge of the main body disc 21 is sequentially provided with a first recess 221, a short groove 2222, a long groove 2221, a long groove 2221, a short groove 2222, and a first recess 221. It can be understood that the length of the second recess 222 is shortened at the position close to the first recess 221, so as to ensure the material thickness between the end of the short groove 2222 and the end of the first recess 221, and prevent the main body disc 21 from being broken; at the same time, the water spraying effect of the splashback disc 20 can be ensured.

[0037] Further, the depth difference between the long grooves 2221 and the short grooves 2222 is 0.7-1.1 mm. It can be understood that, in the embodiment, in order to facilitate processing, the first recesses 221 and the second recesses 222 are U-shaped grooves. The depth difference between the long grooves 2221 and the short grooves 2222 is the radius of the end arc of the second recess 222.

[0038] Optionally, the width of the groove 22 is 2-2.5 mm. The thickness of the splashback disc 20 is 0.8-1.2 mm. Specifically, in the embodiment, the number of the first grooves 221 is four, and the number of the second grooves 222 is eight. The first grooves 221 and the second grooves 222 are evenly arranged along the edges of the main disc 21, respectively. The width of the groove 22 can be set according to the number of the groove 22. For example, when the number of the groove 22 is increased, the width of the groove 22 is reduced; when the number of the groove 22 is reduced, the width of the groove 22 is increased.

[0039] Further, in order to further enhance the water sprinkling and fire extinguishing effect, a through hole 24 is arranged at the center of the main disc 21. It can be understood that when the splashback disc 20 is installed on the nozzle 100, the water outlet of the nozzle 100 is coaxially arranged with the through hole 24, so that part of the water flow sprayed by the nozzle 100 is sprinkled from the through hole 24 at the center of the splashback disc 20, and the fire extinguishing effect of the nozzle 100 directly below is ensured.

[0040] Second embodiment

[0041] Please refer to Figure 2 and Figure 3 , the embodiment provides a nozzle 100, which comprises a nozzle body 10, a splashback disc 20 of the first embodiment and a thermal sensitive assembly 30. The nozzle body 10 comprises a receiving cavity 12. A connecting rod 14 is fixed in the connecting hole 23. The connecting rod 14 is in sliding connection with the nozzle body 10, so that the splashback disc 20 can slide in the receiving cavity 12. The thermal sensitive assembly 30 is used to close the receiving cavity 12. The thermal sensitive assembly 30 is used to fall off when the temperature reaches a preset value.

[0042] Optionally, the nozzle 100 in the embodiment is in flush structure. In other embodiments, the nozzle 100 can be in other structures, such as embedded structure, concealed structure, etc. It can be understood that the flush structure refers to the nozzle 100 partially or entirely installed below the ceiling plane, and the thermal sensitive assembly 30 is below the nozzle 100. The embedded structure refers to the nozzle 100 entirely or partially installed in the shroud embedded in the ceiling. The concealed structure refers to the embedded nozzle 100 with a decorative cover plate. The embodiments of the utility model do not limit the type of the nozzle 100.

[0043] Specifically, the nozzle body 10 is provided with a water flow channel 11. The water flow channel 11 is in communication with the receiving cavity 12. The nozzle body 10 is further provided with a matching hole 13. The connecting rod 14 passes through the matching hole 13, and the end of the connecting rod 14 is fixed with the splashback disc 20 through the connecting hole 23. The end of the connecting rod 14 away from the splashback disc 20 is provided with a limiting piece to prevent the connecting rod 14 from sliding out of the matching hole 13. It can be understood that the connecting rod 14 slides relative to the matching hole 13, so that the splashback disc 20 is close to or away from the nozzle body 10.

[0044] Specifically, the heat-sensitive assembly 30 comprises the plugs 31 and the heat-sensitive glass 32. The plugs 31 are supported by the heat-sensitive glass 32 at the opening of the accommodating cavity 12. When the temperature reaches the preset value, the heat-sensitive glass 32 bursts, so that the plugs 31 are separated from the accommodating cavity 12.

[0045] It can be understood that the plugs 31 comprise the supporting heads 311. The supporting heads 311 abut against the inner wall of the accommodating cavity 12, so as to lift the splash plate 20 to block the water outlet of the nozzle body 10. The heat-sensitive glass 32 is supported between the supporting heads 311. When the temperature reaches the preset value, i.e. the temperature of the heat-sensitive glass 32 is increased by a certain value due to the fire, the heat-sensitive glass 32 bursts. The supporting force between the supporting heads 311 is lost, so that the abutment against the inner wall of the accommodating cavity 12 is lost, and the plugs 31 fall from the accommodating cavity 12. The splash plate 20 falls under the action of gravity until the limiting piece of the connecting rod 14 abuts against the nozzle body 10, and the splash plate 20 falls into place. The nozzle body 10 sprays water, and the falling water flow is splashed from the grooves 22 around the splash plate 20, and the fire extinguishing is completed.

[0046] The splash plate 20 of the nozzle 100 provided by the embodiment has the following beneficial effects:

[0047] The splash plate 20 comprises the main plate 21. The edge of the main plate 21 is provided with a plurality of grooves 22. When the nozzle 100 sprays water on the splash plate 20, the water flow can flow out from the grooves 22 around the main plate 21, the water spraying range is increased, the water spraying is more uniform, and better fire extinguishing effect is achieved. At least two connecting holes 23 are further formed in the main plate 21. The connecting holes 23 are arranged at the edge position of the main plate 21. The connecting holes 23 are used for detachable connection with the nozzle 100 through the fixing structure, so as to facilitate installation of the new heat-sensitive assembly 30. When the heat-sensitive assembly 30 is not needed to be used, the splash plate 20 is hidden in the nozzle 100, so as to facilitate installation of the heat-sensitive assembly 30 and make the structure beautiful.

[0048] The preferred embodiments of the utility model are merely used for limiting the utility model, and for the person skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
