The vehicle body 10 has a containing cavity 11 containing water. The water spraying assembly 20 comprises a spray head 21 and a water inlet pipe 22. The spray head 21 is arranged on the vehicle body 10. The water inlet pipe 22 has a first water inlet 221 and a first water outlet 222. The first water inlet 221 extends into the containing cavity 11. The spray head 21 is in communication with the first water outlet 222. The control assembly 30 comprises a sealed box 31, a driving member 32 and a piston member 33. The sealed box 31 is arranged in the containing cavity 11 and has a conveying cavity 311. The sealed box 31 has a second water inlet 312 in communication with the containing cavity 11 and a second water outlet 313 in communication with the first water inlet 221. The piston member 33 is movably arranged in the conveying cavity 311. The piston member 33 is in close fit with the side wall of the sealed box 31. The driving member 32 is arranged on the sealed box 31 and is in driving connection with the piston member 33 to drive the piston member 33 to move up and down along the sealed box 31. The second water inlet 312 is provided with a first opening and closing member 40. The second water outlet 313 is provided with a second opening and closing member 50. When the piston member 33 moves upward, the second opening and closing member 50 is in sealing fit with the second water outlet 313. The first opening and closing member 40 moves upward to avoid the second water inlet 312 so as to make the containing cavity 11 in communication with the conveying cavity 311. When the piston member 33 moves downward, the first opening and closing member 40 moves downward to be in close fit with the side wall of the second water inlet 312. The second opening and closing member 50 moves toward a direction away from the second water outlet 313 so as to make the conveying cavity 311 in communication with the first water inlet 221.

[0042] The fire extinguishing robot provided by the embodiment comprises a vehicle body 10, a water spraying assembly 20 and a control assembly 30. The water spraying assembly 20 and the control assembly 30 are arranged on the vehicle body 10, a spray head 21 of the water spraying assembly 20 is arranged on the vehicle body 10, a first water inlet 221 of a water inlet pipe 22 of the water spraying assembly 20 extends into a containing cavity 11 of the vehicle body 10, a first water outlet 222 of the water inlet pipe 22 is in communication with the spray head 21, and thus the water in the containing cavity 11 is sprayed out through the water inlet pipe 22 and the spray head 21. In order to avoid that the water column sprayed by the spray head 21 extinguishes the electric object, causing the electric conduction through the sprayed water column to the human body and resulting in the electric shock accident, the control assembly 30 is arranged on the vehicle body 10. A sealing box 31 in the control assembly 30 is arranged in the containing cavity 11. The sealing box 31 has a conveying cavity 311. The sealing box 31 is in communication with the containing cavity 11 through a second water inlet 312 and is in communication with the first water inlet 221 through a second water outlet 313. A piston 33 is arranged in the conveying cavity 311. A driving member 32 is arranged on the sealing box 31 and drives the piston 33 to move up and down along the sealing box 31. A first opening and closing member 40 is arranged at the second water inlet 312, and a second opening and closing member 50 is arranged at the second water outlet 313. When the piston 33 moves upward, the piston 33 is in sealing fit with the conveying cavity 311, so that when the piston 33 moves upward, the conveying cavity 311 is in a negative pressure state. At this time, the first opening and closing member 40 is opened, so that the conveying cavity 311 is in communication with the containing cavity 11, and the water can enter the conveying cavity 311. The second opening and closing member 50 is in a closed state. When the piston 33 moves downward, the conveying cavity 311 is in a positive pressure state. At this time, the first opening and closing member 40 is switched from the opened state to the closed state, so that the conveying cavity 311 is isolated from the containing cavity 11. The second opening and closing member 50 is switched from the closed state to the opened state, so that the conveying cavity 311 is in communication with the first water inlet 221, and the water can enter the water inlet pipe 22 and be sprayed out by the spray head 21. By the cooperation of the driving member 32, the piston 33, the sealing box 31, the first opening and closing member 40 and the second opening and closing member 50, when the piston 33 moves upward, the spray head 21 does not spray water, and the conveying cavity 311 stores water. When the piston 33 moves downward, the water in the conveying cavity 311 enters the spray head 21 through the water inlet pipe 22 and is sprayed out by the spray head 21. The piston 33 moves up and down to realize the intermittent water spraying effect of the spray head 21, thereby solving the problem in the related art that the continuous water column spraying by the fire-fighting robot in the non-electric operation condition can cause the electric conduction through the sprayed water column to the human body, and the fire-fighting personnel are prone to the electric shock danger.
