[0069] like Fig.12 As shown, a clearance groove 44 is provided in the first partition plate 18, a third bracket 43 is welded and fixed in the clearance groove 44, a fourth motor 40 is bolted on the third bracket 43, and an output shaft of the fourth motor 40 is coaxially fixedly connected to a third fan 38 for extracting smoke. The fourth motor 40 is electrically connected to the control center.

[0070] The top of the first partition 18 is fixedly connected to the second connecting pipe 41, which connects the water storage tank 2 and the clearance groove 44. The bottom of the first partition 18 is fixedly connected to the first connecting pipe 39, which connects the clearance groove 44 and the detection chamber 14. It is used to transfer the detected smoke in the detection chamber 14 to the water storage tank 2.

[0071] A one-way valve 42 is fixedly installed in the second connecting pipe 41 , and the one-way valve 42 is used to ensure that smoke can enter the water storage tank 2 from the second connecting pipe 41 , while ensuring that liquid and smoke in the water storage tank 2 cannot enter the second connecting pipe 41 .

[0072] Working principle: When in use, first start the smoke sensor 11 and the temperature sensor 16. Then start the second motor 25 and the third motor 32. Thereafter, the output shaft of the second motor 25 drives the first fan 24 to rotate, and the first fan 24 draws the smoke outside the detection box 1 into the constant temperature chamber 37 through the air inlet pipe 7. The output shaft of the third motor 32 drives the second fan 35 to rotate, and the second fan 35 draws the air outside the detection box 1 into the second air duct 20.

[0073] At this time, the temperature sensor 16 detects the temperature data of the smoke in the constant temperature chamber 37. If the smoke temperature is at a suitable detection temperature of the smoke sensor 11, the third valve 36 is controlled by the control center to open the connecting hole on the second partition 19, and the smoke in the constant temperature chamber 37 enters the detection chamber 14 through the connecting hole.

[0074] Afterwards, the detection head 17 of the smoke sensor 11 detects the smoke in the detection chamber 14, and transmits the data back to the control center after the detection is completed. Finally, the control center transmits the data to a receiving terminal such as a fire room.

[0075] Next, the control center starts the fourth motor 40, and the output shaft of the fourth motor 40 drives the third fan 38 to rotate. The third fan 38 draws the detected smoke in the detection chamber 14 into the make way groove 44 through the first connecting pipe 39. The smoke drawn into the make way groove 44 finally enters the water storage tank 2 through the second connecting pipe 41 and the one-way valve 42.

[0076] At the same time, cold water is introduced into the liquid inlet pipe 21, and the cold water flows into the cooling box 6 and cools down the air in the second air duct 20, thereby finally forming cold air. The cold water after temperature exchange is discharged through the liquid outlet pipe 22. The cold water can be introduced into the liquid inlet pipe 21 through a water tank and a water pump, wherein the water tank is fixedly mounted on the robot body and filled with cold water before use. When cold water is needed, the water pump is controlled by the control center to introduce cold water into the liquid inlet pipe 21.

[0077] Then the cold air in the second air duct 20 is blown to the heat dissipation box 10 by the second fan 35, and the cold air blown into the heat dissipation box 10 cools down and dissipates the heat of the smoke sensor 11. At this time, the cold air absorbs heat and is converted into hot air, and then the generated hot air is transported from the heat dissipation box 10 to the first air duct 12. Finally, the hot air is blown to the outside of the detection box 1 through the exhaust port of the exhaust box 33.

[0078] During use, if the temperature sensor 16 detects that the smoke temperature in the constant temperature chamber 37 is greater than the appropriate detection temperature of the smoke sensor 11, the temperature sensor 16 transmits the data to the control center, and the control center controls the second valve 29 to open the second exhaust pipe 28, and at the same time controls the valve core of the first flap valve 23 to flip and open the through hole 13. After the valve core of the first flap valve 23 flips, the valve core blocks the gas flow channel in the second air duct 20, and at this time the valve core is in sealing contact with the branch plate 52 in the second air duct 20.

[0079] At the same time, part of the cold air in the second air duct 20 is blown toward the heat dissipation box 10 from the upper gas flow channel, and the other part of the cold air is blown into the through hole 13 connected to the second air duct 20 from the lower gas flow channel. This part of the cold air flows into the gas storage chamber 15 through the through hole 13, thereby cooling the smoke in the constant temperature chamber 37, so that the smoke temperature in the constant temperature chamber 37 reaches the appropriate detection temperature of the smoke sensor 11.

[0080] The cold air in the air storage chamber 15 exchanges temperature with the smoke in the constant temperature chamber 37 and then is discharged from the detection box 1 through the second exhaust pipe 28 .

[0081] Similarly, if the temperature sensor 16 detects that the smoke temperature in the constant temperature chamber 37 is lower than the appropriate detection temperature of the smoke sensor 11, the temperature sensor 16 transmits the data to the control center, and the control center controls the first valve 27 to open the first exhaust pipe 9, and controls the valve core of the second flap valve 30 to flip and open the through hole 13. After the valve core of the second flap valve 30 flips, the valve core blocks the gas flow channel in the first air duct 12, and at this time, the valve core is in sealing contact with the branch plate 52 in the first air duct 12.

[0082] At the same time, part of the hot air in the first air duct 12 is blown from the upper gas flow channel to the exhaust box 33, and the other part of the hot air is blown from the lower gas flow channel into the through hole 13 connected to the first air duct 12. This part of the hot air flows into the gas storage chamber 15 through the through hole 13, thereby heating the smoke in the constant temperature chamber 37 so that the smoke in the constant temperature chamber 37 reaches a suitable detection temperature for the smoke sensor 11.

[0083] The hot air in the air storage chamber 15 exchanges temperature with the smoke in the constant temperature chamber 37 and then is discharged from the detection box 1 through the first exhaust pipe 9 .

[0084] In the process of cooling or heating the smoke in the constant temperature chamber 37, before the smoke temperature reaches the appropriate detection temperature of the smoke sensor 11, the control center controls the third valve 36 in the connection hole to always close the connection hole. When the appropriate detection temperature of the smoke sensor 11 is reached, the control center controls the third valve 36 to open the connection hole.

[0085] Before starting the second motor 25, add the smoke absorbing treatment liquid into the water storage tank 2 through the liquid adding pipe 4. The addition can be done through a medicine water tank and a water pump. The principle of the addition is the same as that of introducing cold water into the liquid inlet pipe 21, so it will not be described in detail here.

[0086] When the third valve 36 opens the connection hole, the control center controls the first motor 3 to rotate, the output shaft of the first motor 3 drives the rotating shaft 49 to rotate, and the rotating shaft 49 drives the scraper 48 and the stirring rod 50 to rotate. The scraper 48 scrapes the material adhered to the inner wall of the water storage tank 2, and the stirring rod 50 stirs the treatment liquid to accelerate the reaction between the treatment liquid and the smoke.

[0087] When the smoke detection is finished, the control center controls all the controlled electrical components to be restored, and at the same time controls the fourth valve 51 to open the external pipe 46. At this time, the treated liquid that has reacted with the smoke, i.e., the waste liquid, is discharged from the water storage tank 2 from the drain pipe 47 and the external pipe 46 in sequence. After the waste liquid is discharged, the control center controls the fourth valve 51 to close the external pipe 46.

[0088] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
