[0018] Figure 4 This is a sectional view of the connecting column and the collection box section. Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 A fire smoke detector cleaner includes a housing 1, a connecting column 2 slidably disposed on the inner side of the housing 1, and an adjustment structure disposed between the housing 1 and the connecting column 2.

[0021] like Figure 2-3 The adjustment structure includes a first gear 10, which is rotatably mounted on the inner bottom of the outer casing 1. Two second gears 11 are meshed on the outer side of the first gear 10. Both second gears 11 are rotatably mounted on the inner bottom of the outer casing 1. A screw 12 is fixedly mounted on the top of each of the two second gears 11. The threads on the outer sides of the two screws 12 are the same. Moving blocks 13 are threadedly connected to the outer sides of the two screws 12. The two moving blocks 13 are fixedly mounted on both sides of the connecting column 2 at symmetrical positions.

[0022] like Figure 2-3 The top of the outer shell 1 is provided with a first longitudinal sliding groove, and the moving blocks 13 on both sides of the connecting column 2 are both set inside the first sliding groove and can slide inside the outer shell 1.

[0023] like Figure 2-3 The bottom of gear 10 is fixedly connected to shaft 14, which is rotatably connected to housing 1. A worm gear 15 is fixedly mounted through housing 1 at its bottom end. Two fixed seats 16 are fixedly mounted at the bottom of housing 1, and a worm 17 is rotatably mounted between the two fixed seats 16. The worm gear 15 and worm 17 are meshed together. One end of the worm 17 passes through one of the fixed seats 16 and is fixedly mounted with a throttle 18. Thus, the throttle 18 serves as the driving force for the rotation of gear 10.

[0024] A collection frame 3 is fixedly installed on the top of the connecting column 2. A cleaning spray ring 4 is fixedly installed on the inner side of the collection frame 3. A delivery pipe 5 is fixedly installed on the outer side of the cleaning spray ring 4. A perforated limiting seat 6 is fixedly installed on the outer side of the outer shell 1. One end of the delivery pipe 5 passes through the collection frame 3 and the perforated limiting seat 6 and is installed in conjunction with the perforated limiting seat 6.

[0025] A connecting seat 7 is fixedly installed on the outside of the connecting column 2. A collection tank 8 is fixedly installed on the top of the connecting seat 7. A collection pipe 9 is fixedly installed on the top of the collection tank 8. One end of the collection pipe 9 is connected to the bottom of the collection frame 3.

[0026] For the structural technology of the connecting seat 7 and the collection tank 8, the specific structure of a cleaning device for a smoke and heat detector for fire protection maintenance can be adopted, as disclosed in CN220072572U.

[0027] A rotating shaft 21 is rotatably installed on the inner bottom of the collection frame 3, and a cleaning scraper 22 is fixedly installed on the outer side of the rotating shaft 21. The cleaning scraper 22 is located on the inner side of the collection frame 3 and slides in contact with the collection frame 3.

[0028] A rotating cylinder 19 is fixedly installed on the top of the first gear 10. The rotating cylinder 19 is rotatably connected to the connecting column 2. A polygonal groove is opened on the top of the rotating cylinder 19. A polygonal column 20 is fixedly installed through the bottom of the rotating shaft 21 through the collection frame 3. The polygonal column 20 is set inside the polygonal groove and can allow the rotating cylinder 19 and the polygonal column 20 to slide relative to each other in the vertical direction.

[0029] It should be noted that this utility model is a fire smoke detector cleaner.

[0030] Its working principle is as follows:

[0031] When in use, connect the external water source to the delivery pipe 5, then cover the fire smoke detector that needs to be cleaned with the collection frame 3, and then the water will be sprayed through the cleaning spray ring 4 to clean the fire smoke detector. The cleaned wastewater will flow into the cleaning spray ring 4 and then enter the collection tank 8 through the collection pipe 9 at the bottom of the cleaning spray ring 4 for unified filtration and collection.

[0032] When the height of the device needs to be adjusted according to the position of the fire smoke detector, turning the handle 18 drives the worm gear 17 to rotate, which in turn drives the worm wheel 15 to mesh and rotate. Then, through the connecting shaft 14, it drives the second gear 11 to rotate, which in turn drives the two second gears 11 to mesh and rotate, which in turn drives the two screws 12 to rotate, thereby moving the two moving blocks 13 to move, thereby adjusting the position of the connecting column 2 and the collection frame 3 on its top (assuming the outer shell 1 is stationary). This facilitates cleaning of fire smoke detectors of different heights, is simple to operate, and improves the convenience of using the device.

[0033] During the height adjustment of the device, gear 10 drives the rotating drum 19 to rotate (the rotating drum 19 only rotates and does not move vertically), which in turn drives the polygonal column 20 located inside the polygonal groove of the rotating drum 19 to rotate (during the up and down movement of the connecting column 2, the collection frame 3, the rotating shaft 21, and the polygonal column 20 all move synchronously. At this time, the rotating drum 19 does not move vertically, and the two are adaptively adjusted by "the rotating drum 19 and the polygonal column 20 can slide relative to each other in the vertical direction"). This drives the rotating shaft 21 to rotate, which in turn drives the cleaning scraper 22 to make a circular motion with the rotating shaft 21 as the center, to scrape off the impurities on the inner wall of the collection frame 3. Relying on the cleaning water of the next cleaning, the "scraped-off impurities" enter the collection tank 8 through the collection pipe 9 for unified filtration and collection, which effectively improves the use effect of the device.

[0034] For other details, please refer to the existing technology.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
