When the mounting seat 81 is not required to be moved to clean the lighting lamp 71, the mounting seat 81 is positioned in the placing cavity 19, the second magnetic block 21 always keeps the trend of sliding along the direction close to the first magnetic block 20 under the attraction of the first magnetic block 20, and the transfusion seat 15 is positioned in the placing groove 16 under the action of the second magnetic block 21 and the first magnetic block 20 to push the spring 22 to be in a compression deformation state at the moment; the sealing pad 17 is elastically reset to seal the placing groove 16, so that the infusion cotton is prevented from being completely exposed, and the liquid adsorbed on the infusion cotton is prevented from drying in a long-term high-temperature environment.
When the illumination lamp 71 needs to be cleaned, the second motor 101 drives the mounting seat 81 to slide, the mounting seat 81 is far away from the placing cavity 19, the second magnetic block 21 is far away from the second magnetic block 21, when the second magnetic block 21 is not attracted by the first magnetic block 20 any more, the reset of the pushing spring 22 drives the transfusion seat 15 to slide, so that the transfusion seat 15 is driven to be far away from the placing groove 16, and the sealing pad 17 is propped up in the sliding process of the transfusion seat 15, so that the transfusion cotton in the transfusion seat 15 slides out through the placing groove 16 until the transfusion cotton is attached to the cleaning cloth 9; the infusion cotton is attached to the cleaning cloth 9 to convey liquid to the cleaning cloth 9, the liquid can be water or special cleaning liquid, in the process that the second motor 101 drives the mounting seat 81 to slide, the infusion cotton is attached to the cleaning cloth 9, so that the cleaning cloth 9 is adsorbed with the liquid, the lighting lamp 71 can be cleaned by using the liquid in the process that the cleaning cloth 9 moves, and therefore the lighting lamp 71 is cleaned in a wet mode, and a better cleaning effect is achieved.
The implementation principle of the embodiment 2 is as follows: the second motor 101 operates to drive the mounting seat 81 to slide, the sliding of the mounting seat 81 drives the cleaning cloth 9 to slide on the illuminating lamp 71, the cleaning cloth 9 is kept attached to the outer wall of the illuminating lamp 71 in the sliding process of the cleaning cloth 9, and the cleaning cloth 9 cleans the illuminating lamp 71; before the illumination lamp 71 is operated, the illumination lamp 71 can be cleaned before the illumination lamp 71 is operated by the cooperation of the mounting seat 81 and the cleaning cloth 9, so that the smoke generated by flame combustion in the burner is prevented from being attached to the illumination lamp 71, and the illumination lamp 71 emits light which is difficult to detect by the flame probe 2.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
