The drainage assembly 2 includes a drainage tube 21 and an injection tube 22 connected thereto. An end of the drain tube 21 remote from the spray tube 22 can communicate with the purge line 11 and the purge line 12. The air outlet of the air supply source is selectively communicated with one end of the cleaning pipeline 11 far away from the drainage pipe 21 or one end of the purging pipeline 12 far away from the drainage pipe 21.
When the cleaning maintenance device is used, first, the air outlet of the air supply source is communicated with the purge line 11 to enter a purge mode. The cleaning pipeline 11 is provided with a water mist generator 111. Clean water is stored in the water mist generator 111, and the clean water can be converted into water mist. In the cleaning mode, the air supply source can introduce compressed air into the cleaning pipeline 11, and the compressed air brings the water mist generated by the water mist generator 111 into the drainage tube 21 and finally is ejected out of the nozzle of the ejection tube 22. Due to the driving action of the compressed gas, the water mist sprayed out through the nozzle of the spray pipe 22 has a certain pressure, which can wash away dust and dirt on the surface of the flame detector probe.

In this embodiment, the injection pipe 22 is a 1/4in gauge pipe, which ensures that the water mist and the compressed gas inside the pipe have sufficient pressure.
Further, the injection pipe 22 is an elbow so that the injection pipe 22 can clean or purge the probe of the flame detector from the side. Preferably, the nozzle of the end of the injection pipe 22 remote from the draft tube 21 is a flat port through which the water mist or dry compressed gas is injected to increase the pressure at which the water mist and compressed gas are injected, thereby enabling the surface of the probe to be cleaned or purged.
It should be noted that the pressure when the water mist and the compressed gas are sprayed should be less than the safety threshold, that is, the water mist and the compressed gas have a certain safety pressure when being sprayed out from the spraying pipe 22, which not only can effectively clean or purge the surface of the probe, but also can avoid the damage to the probe caused by the over-pressure.
It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention.
