Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of fire-fighting equipment, especially fire-fighting control and spray head. BACKGROUND

[0002] The existing fire-fighting is mostly set in two parts, China patent CN117919629A discloses an integrated battery box fire-fighting spray head, including control system, sensing device and nozzle and valve, spray head body is sealed and screwed on battery box and is set in battery box inside probe sensor and circuit board, which is set on spray head body and is set in battery box inside. Although the scheme realizes the integrated setting of probe and spray head, the probe sensor and circuit board are integrally arranged on the spray head body, which affects the design of the circuit board due to the small size of the spray head body. In addition, the opening and closing of the spray head is realized by turning the plate, which increases the design difficulty. SUMMARY

[0003] The utility model aims to provide an integrated detection fire-fighting device.

[0004] To achieve the above purpose, the utility model discloses an integrated detection fire-fighting spray head, which is composed of a shell and a detection device and a spraying part arranged in the shell. The detection device includes a detector circuit board, a smoke opening formed in the shell body, and a smoke chamber arranged in the shell and communicating with the smoke opening. The detection sensor of the detector circuit board is arranged in the smoke chamber. The spraying part is composed of an internal spray head body arranged in the body, a fire extinguishing agent quick connector, an atomizing spray head, and a movable plug pressed by a temperature-sensitive device. The internal spray head body has two sections, i.e., a fire extinguishing agent input end and an output end. The fire extinguishing agent quick connector is connected to the fire extinguishing agent input end at one end and to an external fire extinguishing agent pipeline at the other end. The output end of the internal spray head body is connected to the atomizing spray head, and the nozzle of the atomizing spray head extends out of the shell. A control opening is arranged between the fire extinguishing agent input end and the output end of the internal spray head body. The movable plug mentioned above can be closed and arranged in the control opening to realize the opening and closing of the internal spray head body pipeline.

[0005] The temperature-sensitive device is a temperature-sensitive glass ball, and a heating coil is arranged on the temperature-sensitive glass ball.

[0006] The internal spray head body is in the shape of a "T". One side shoulder of the "T" is the fire extinguishing agent input end, and the fire extinguishing agent input end and the output end form a 90° angle. The fire extinguishing agent input end is screwed with the fire extinguishing agent quick connector, and the inner end of the fire extinguishing agent input end forms a "V"-shaped opening to form a control opening. One end of the movable plug adapted to the control opening can be pressed on the control opening.

[0007] The other side shoulder of the "T" of the internal spray head body is screwed with a temperature-sensitive device support. The temperature-sensitive device is clamped in the support and pressed on the movable plug.

[0008] By adopting the above solution, this utility model integrates the detector and the nozzle into one housing, and the detector circuit board has more design space to improve the detection accuracy. The temperature-sensing glass ball and the movable plug act like a faucet valve to control the opening and closing of the nozzle, making the design more reasonable. Attached Figure Description

[0015] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0016] Please see Figure 1 , 2 This utility model discloses an integrated fire sprinkler head. The outer casing 1 is screwed together by a top cover 11 and a housing 12. A smoke opening 121 is provided at the lower part of the housing 12. The detection device 2 consists of a detector circuit board 21, a detection sensor 211, and a smoke chamber 23. The detector circuit board 21 is sealed between the top cover 11 and the upper part of the housing 12 by a sealing ring 24. An indicator light 6, electrically connected to the detector circuit board 21, is provided on the top cover 11. The housing 12 contains a smoke chamber 23 communicating with the smoke opening 121. The detection sensor 211, mounted on the detector circuit board 21, extends into the smoke chamber 23. The detection sensor 211 includes at least one of the following: a carbon monoxide sensor, a VOC sensor, a temperature sensor, and a smoke sensor.

[0017] like Figure 1 , 2As shown in Figure 3, the spraying unit 3 inside the housing 12 consists of an internal nozzle body 31, an extinguishing agent input end 311, an output end 312, a control opening 313, an extinguishing agent quick connector 32, an atomizing nozzle 33, a temperature-sensing glass bulb support 34, and a movable plug 35. The internal nozzle body 31 is T-shaped, with the extinguishing agent input end 311 located on the right shoulder of the T-shape. The extinguishing agent input end 311 is screwed to the outer end of the extinguishing agent quick connector 32, which connects to an external extinguishing agent pipeline. The extinguishing agent input end 311 and the output end 312 form a 90° angle. The output end 312 connects to the atomizing nozzle 33, and the nozzle of the atomizing nozzle 33 extends out of the housing 12 of the main body. The inner end of the extinguishing agent inlet 311 has a "V"-shaped opening to form a control opening 313. The other shoulder of the "T"-shaped nozzle body is screwed to a temperature-sensitive thermistor bracket (the temperature-sensitive thermistor is one of a temperature-sensitive glass ball, a hot-melt metal, or a shape memory alloy; in this example, it is a temperature-sensitive glass ball 4). The temperature-sensitive glass ball 4 is mounted on the temperature-sensitive glass ball bracket 34 and presses against the movable plug 35. The other end of the movable plug is adapted to the "V"-shaped opening of the aforementioned control opening 313, and the movable plug 35 can be movably pressed against the control opening 313.

[0018] A heating coil (not shown in the known technical diagram) connected to the detector circuit board 21 is wound around the temperature-sensing glass bulb 4. The temperature-sensing glass bulb 4 can shatter in the following ways: 1. Thermal runaway reaches the set temperature of the temperature-sensing glass bulb, causing it to shatter automatically; 2. After the temperature and gas detected by the sensor reach the set value, the control circuit activates the heating wire to heat the temperature-sensing glass bulb, causing it to shatter automatically; 3. The control system detects thermal runaway and needs to activate the fire sprinkler head, so the control circuit activates the heating wire to heat the temperature-sensing glass bulb, causing it to shatter automatically.

[0019] like Figure 1 As shown, a quick-connect connector 5 is provided on the housing, through which the wiring harness of the detector circuit board 21 and the wiring harness of the control center can be quickly plugged in and connected.

[0020] like Figure 2 , 4 As shown, in the operation of this integrated fire sprinkler head, the heat-sensing glass bulb 4 presses against the movable plug 35, blocking the input end of the extinguishing agent (equivalent to closing a faucet valve), preventing the extinguishing agent from being sprayed from the atomizing nozzle 33. When thermal runaway occurs, and the three conditions mentioned above for the heat-sensing glass bulb to shatter are met, the heat-sensing glass bulb 4 breaks, and the movable plug 35 moves to the left under the pressure of the extinguishing agent, connecting the input end 311 and the output end of the extinguishing agent, allowing the extinguishing agent to be sprayed from the atomizing nozzle 33. Figure 4 (Arrow line).

Any equivalent shape or structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
