[0002] like Figure 1 As shown, a smoke detector 2 is installed on the ceiling 1 of the building, and a detection port 3 is opened on the side wall of the smoke detector 2. The inspection personnel generally use a fire inspection smoke gun to spray smoke at the detection port 3 of the smoke detector 2 to test whether the smoke detector 2 is operating normally. The existing fire inspection smoke gun includes a vertical telescopic rod 8, a heater 7 is installed on the top wall of the heater 7, a smoke oil bin 6 is installed on the top wall of the heater 7, a nozzle 5 is installed on the top wall of the smoke oil bin 6, and a horizontal rod-shaped nozzle 9 is provided on the side wall of the nozzle 5. The proximal end of the rod-shaped nozzle 9 is installed on the left side wall of the nozzle 5 and connected to the nozzle 5, and the distal end extends horizontally to the right. The inspection personnel hold the telescopic rod 8 of the fire inspection smoke gun, push the telescopic rod 8 upward until the rod-shaped nozzle 9 is horizontally aligned with the detection port 3 of the smoke detector 2, the heater 7 heats the smoke oil bin 6 so that the smoke oil in the smoke oil bin 6 is heated and atomized, the smoke first reaches the rod-shaped nozzle 9 through the nozzle, and then sprays into the detection port 3 of the smoke detector 2, and the smoke detector 2 detects the smoke and alarms. The defect of the prior art is that the inspector holds the telescopic rod 8 and makes the rod-shaped nozzle 9 approach the detection port 3 of the smoke detector 2 to spray smoke. If the inspector is not skilled, the rod-shaped nozzle 9 may be mistakenly extended into the detection port 3 of the smoke detector 2, causing damage to both. Utility Model Content
[0003] The utility model aims to provide a durable fire detection smoke spray gun, whose rod-shaped nozzle is not easy to be damaged; and also provides a fire detection system using the fire detection smoke spray gun, whose rod-shaped nozzle and the detection port of the smoke detector are not easy to be damaged.

[0005] Furthermore, the anti-collision block is specifically a horizontal U-shape, and the U-shaped opening is horizontally facing right so that: the U-shaped inner wall serves as the right side wall of the anti-collision block, and the U-shaped outer wall serves as the left side wall of the anti-collision block.
[0006] Furthermore, a buffer pad is arranged on the top wall of the nozzle.
[0007] Furthermore, the interior of the anti-collision block is a cavity, and the cavity serves as the smoke outlet channel. The channel has only one inlet and multiple outlets.
[0008] Furthermore, it comprises a smoke detector, a detection port is opened on the side wall of which; and it comprises the fire detection smoke gun, the U-shaped inner wall of the anti-collision block is adapted in shape and size to the side wall of the smoke detector.
[0009] Furthermore, the anti-collision block is adapted to the thickness of the smoke detector.
[0010] The beneficial effect is that the anti-collision block is mounted on the distal end of the rod-shaped nozzle of the fire detection smoke gun, and the rod-shaped nozzle is protected by the anti-collision block and is not easily damaged. For the fire detection system using the fire detection smoke gun, the anti-collision block can prevent the rod-shaped nozzle from accidentally extending into the detection port of the smoke detector, so that the smoke sensing element in the detection port of the smoke detector is not easily hit and is not easily damaged.

[0015] The invention of the utility model is further described in detail below in conjunction with specific implementation methods.
[0016] like Figure 2 As shown, the fire detection smoke gun includes a vertical telescopic rod 8, a heater 7 is mounted on the top wall of the heater 7, a smoke oil tank 6 is mounted on the top wall of the heater 7, a nozzle 5 is mounted on the top wall of the smoke oil tank 6, and a horizontal rod-shaped nozzle 9 is arranged on the side wall of the nozzle 5. The proximal end of the rod-shaped nozzle 9 is mounted on the left side wall of the nozzle 5 and connected to the nozzle 5, and the distal end extends horizontally to the right and is equipped with an anti-collision block 10. Figure 3 As shown, the anti-collision block 10 is a horizontal U-shape, with the U-shaped opening facing horizontally to the right, and the internal cavity serves as a smoke outlet channel 15; the U-shaped inner wall serves as the right side wall of the anti-collision block 10, and is provided with multiple channel outlets 11; the U-shaped outer wall serves as the left side wall of the anti-collision block 10, and is provided with only one channel inlet 14, which is connected to the rod-shaped nozzle 9.
[0017] A cushion 12 is installed on the top wall of the nozzle 5. The inspector holds the telescopic rod 8 and pushes the telescopic rod 8 upward until the cushion 12 is against the building ceiling 1. This state represents that the rod-shaped nozzle 9 has been horizontally aligned with the smoke detector 2 installed on the ceiling 1. Then the inspector moves the telescopic rod 8 to the right until the U-shaped inner wall of the anti-collision block 10 is against the left side wall of the smoke detector 2. The heater 7 heats the smoke oil in the smoke oil tank 6 to atomize it. The smoke is ejected through the nozzle 5, the rod-shaped nozzle 9, the channel inlet 14, the smoke outlet channel 15, and the channel outlet 11 in sequence, and then enters the detection port 3 of the smoke detector 2. The smoke detector 2 detects smoke and alarms. This means that the smoke detector 2 is operating normally. The U-shaped inner wall of the anti-collision block 10 is adapted to the side wall of the smoke detector 2 in shape and size, and the anti-collision block 10 is adapted to the thickness of the smoke detector, so that the smoke ejected from the smoke channel outlet 11 can easily enter the detection port 3 directly, and is not easy to escape into the surrounding air and cause other smoke detectors 2 around to alarm.
[0018] The above is only an implementation method of the utility model, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the utility model, which still fall within the scope of patent protection.
