Description

Technical Field

[0001] This utility model belongs to the field of spray heads, specifically, it relates to a dry spray head. Background Technology

[0002] Existing dry sprinkler heads are devices that operate using pressure differences. They can spray water mist or water spray agent when a fire occurs to extinguish the fire.

[0003] Chinese patent application number CN202420043948.4 discloses a dry fire sprinkler head, relating to the field of fire protection facilities technology. This utility model includes a short pipe, a nozzle seat fixedly connected to the bottom of the short pipe, a heat-sensitive glass tube disposed on the bottom of the nozzle seat, a protruding cylinder fixedly connected to the top of the short pipe, external threads on the outer wall of the protruding cylinder, a through pipe disposed inside the protruding cylinder, a ring fixedly connected to the bottom of the through pipe, a pipe plug disposed inside the through pipe, a spring disposed inside the ring, a protruding plate fixedly connected to the bottom end of the spring, and a movable plate fixedly connected to the top end of the spring, with the top surface of the movable plate fixed to the bottom surface of the pipe plug. In this utility model, when the heat-sensitive glass tube bursts, after the compressed air is discharged, water can be sprayed through the four-pronged sprinkler head, resulting in a larger and better flow of fire-fighting liquid, improving fire-fighting performance. Furthermore, the pipe plug, under the action of the spring, is not easily lost and can be reused upon reinstallation, saving costs.

[0004] However, the fixed spray head of the above-mentioned device has certain limitations in actual use, especially when a larger area needs to be covered or a more uniform distribution is required, the fixed spray direction cannot achieve the ideal spraying effect.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0028] Please see Figure 1-4 As shown, this embodiment provides a dry spray head, including a support frame 1 and a rotating spray assembly 2;

[0029] The support frame 1 includes a support frame 101, a support head 102 is provided on one side of the bottom of the support frame 101, a connecting pipe 103 is provided on one side of the support head 102, and a flow rotating head 104 is provided at the top of one end of the connecting pipe 103.

[0030] The rotating spray assembly 2 includes a supporting top plate 201, a supporting rod 202 is provided at the bottom of the supporting top plate 201, a spray pipe 203 is provided at the bottom of the supporting rod 202, one end of the spray pipe 203 is connected to the flow head 104, the other end of the spray pipe 203 is connected to the flow head 204, and a spray head 205 is provided at the bottom of the flow head 204.

[0031] The key innovation of this invention lies in the introduction of a rotatable rod structure, with the spray head 205 mounted on the outer end of the rod. This design improvement allows the spray head 205 to rotate freely within a certain range, thereby increasing the effective coverage area of ​​the spray. Compared to traditional fixed spray heads 205, in the same application scenario, this new spray head 205 can provide more comprehensive and uniform spraying, ensuring that all target areas receive adequate spray treatment. Furthermore, the expanded spray range may reduce the number of spray heads 205 required, thereby lowering installation costs and simplifying maintenance. This innovation is of great significance for improving the efficiency and flexibility of spray systems.

[0032] In terms of usage, the rotating spray assembly 2 can be controlled to rotate by the support frame 101 and the flow rotating head 104 connected by the connecting pipe 103. The top support plate 201, together with the support rod 202 and the spray pipe 203, can be used to control the spraying effect. The spray head 205 sprays at an angle, thereby controlling the spraying effect.

[0033] In this embodiment, a side block 1011 is provided at the bottom of the support frame 101, and a fixing hole 1012 is provided on the outside of the side block 1011. The fixing hole 1012 is used to connect screws so that the object can be fixed to the top of the support frame 101, thereby realizing the stable connection of the support frame 101 for adjustment and control, and facilitating the subsequent connection and fixing of the object.

[0034] In this embodiment, an inlet 1021 is provided on one side of the support head 102, and a flow hole is provided inside the support head 102, so that the liquid can be transmitted through the inlet 1021 to the inside of the connecting pipe 103, thereby realizing the controlled flow of the liquid.

[0035] In this embodiment, the top of the connecting pipe 103 is rotatably connected to the top connecting rotor and is in a flow state. The outside of the flow rotor 104 is provided with a heat-insulating pipe 1041. The other end of the heat-insulating pipe 1041 is connected to the spray pipe 203 to achieve the adjustment and control of liquid transmission. The heat-insulating pipe 1041 is made of soft material, and the outside of the heat-insulating pipe 1041 is provided with heat-insulating material to control heat preservation and liquid transmission.

[0036] In this embodiment, an adjustment head 2021 is provided at the top of the support rod 202. The adjustment head 2021 is rotatably connected to the support top plate 201. The support top plate 201 and the flow rotating head 104 are coaxially distributed, thereby realizing the adjustment and control of the rotation of the external spray head 205 and increasing the spray range.

[0037] In this embodiment, a limiting shell 2051 is provided on the outside of the spray head 205. The limiting shell 2051 is inclined. During use, the inclined setting of the limiting shell 2051 can be used to adjust and control the spray of the spray head 205, thereby realizing the liquid control and transmission. The liquid sprayed at an angle provides power for the spray head 205 to rotate around the supporting top plate 201, thus realizing the function of liquid control and transmission and facilitating the controlled spray transmission of liquid. The structure and principle of the spray head 205 have been described in the prior art and will not be described again in this application.

[0038] In summary, the prior art has already described the structure that can perform spraying. This application provides a rotatable rod with a spray head 205 located at the outer end of the rod, which can increase the spray range of the pipe and make the spraying more comprehensive under the same usage conditions.
