The front outer wall of the box 1 is provided with an alarm 8.

[0023] Specifically, the motor 28 drives the bidirectional threaded rod 25 to rotate, and the rotation of the bidirectional threaded rod 25 drives the water basin 24 and the smoke generator 3 to rise simultaneously and move to the bottom of the fire sprinkler head. Example

[0024] like Figure 1-3 As shown, a water cooling mechanism 4 is provided inside the box 1, and the water cooling mechanism 4 includes a water tank 41, a water pump 42 is fixedly connected to the front of the water tank 41, a copper water pipe 43 is fixedly connected to the front of the water pump 42, the copper water pipe 43 is arranged around the outside of the motor 28, and the rear end of the copper water pipe 43 penetrates into the inside of the water tank 41.

[0026] The working principle of the utility model is as follows:

[0027] When the fire sprinkler head needs to be inspected, the alarm 8 is first turned on to remind the surrounding people to evacuate, and then the motor 28 is turned on to drive the two-way threaded rod 25 to rotate. The rotation of the two-way threaded rod 25 drives the two threaded sleeves 26 to move in a mirror image. The threaded sleeve 26 moves to lift the slider 22 through the movable rod 27. The slider 22 moves upward to drive the supporting plate 23 to move upward. The supporting plate 23 moves upward to drive the water basin 24 to move upward. The water basin 24 moves upward to drive the smoke generator 3 to move upward and move to the bottom of the fire sprinkler head. Then the smoke generator 3 is turned on to release the smoke. If the fire sprinkler head is intact, water mist will be sprayed immediately. The water mist will be received by the water basin 24. The water in the water basin 24 will flow into the water tank 41 through the hose 45. Then the water pump 42 is turned on to pump out the water in the water tank 41, and circulate it in the copper water pipe 43, and cooperate with the heat-conducting copper block 44 to dissipate heat from the motor 28 through the heat transfer principle. This avoids the problem that the motor 28 may be overloaded due to high temperature when the device is tested in a high temperature area such as a boiler room.
