Description

Technical Field

[0001] This application relates to the field of airborne smoke technology, specifically an airborne smoke generator. Background Technology

[0002] Airborne smoke generators used in air shows are systems that produce colored or white smoke using specific technologies, primarily to enhance the visual effects of the air show.

[0003] For example, the patent with publication number CN206218231U discloses a drone-borne smoke device. This patent sets up a gimbal and places a container and a long tube on the gimbal, with a micro pump and a smoke generator inside the gimbal, so that the drone can release smoke during flight, serving as a warning or performance function, thus improving the application level of drones.

[0004] In actual use, if the smoke agent contains undissolved solid particles or chemical residues, they may deposit at the nozzle, easily forming carbonized precipitates that clog the nozzle. This clogging restricts the flow of the smoke agent, directly affecting the concentration and duration of the smoke.

[0005] Therefore, it is necessary to provide an airborne smoke generator to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0036] like Figures 1-3 As shown, this application provides an airborne smoke generator, which is mainly installed on a drone. Specifically, the airborne shooting extension arm includes a base 1 fixedly installed on the drone and an adjustment part 2 provided at the lower end of the base 1. The adjustment part 2 is provided with a spray nozzle 24, so that the angle of the spray nozzle 24 can be adjusted by the adjustment part 2, so that the spray path can be adjusted during the spraying of smoke.

[0037] The adjustment part 2 includes a fixed seat 20 fixedly disposed at the lower end of the base 1, and a rotating shaft 21 rotatably disposed between the fixed seats 20. At the same time, a first motor 22 is fixedly disposed on one side of the fixed seat 20. The output end of the first motor 22 is fixedly connected to the rotating shaft 21, so that starting the first motor 22 can drive the rotating shaft 21 to rotate on the fixed seat 20.

[0038] Furthermore, a fixed ring 23 is provided on the rotating shaft 21, and the spray nozzle 24 is located inside the fixed ring 23. Thus, during the process of spraying smoke, the first motor 22 can be started to drive the rotating shaft 21 to rotate the spray nozzle 24 inside the fixed ring 23, thereby achieving the purpose of angle adjustment.

[0039] Meanwhile, in order to carry out spraying operations smoothly, a mist inlet 25 is provided at one end of the spray nozzle 24. The mist inlet 25 is fixedly connected to an external mist guiding device so that the smoke can be guided into the interior of the spray nozzle 24 through the mist inlet 25 by the external mist guiding device.

[0040] Furthermore, a cover plate 26 is provided at the other end of the spray cylinder 24, and a nozzle 27 is fixedly provided on the cover plate 26. The nozzle 27 passes through the cover plate 26 and is connected to the inside of the spray cylinder 24 so that the smoke inside the spray cylinder 24 can be sprayed out by the nozzle 27.

[0041] Before the spraying operation begins, the smoke is first guided into the spray cylinder 24 through the inlet 25 by the external mist guiding device, and then guided to the outside through the nozzle 27. At the same time as the spraying operation, the first motor 22 can be started to drive the rotating shaft 21 to rotate the spray cylinder 24 inside the fixed ring 23, thereby achieving the effect of angle adjustment.

[0042] During the spraying process, undissolved solid particles or chemical residues may deposit at nozzle 27, causing clogging. To solve this problem, such as... Figure 1 and Figures 3-4 As shown, a scraping mechanism 3 is provided on the cover plate 26. The scraping mechanism 3 includes a second motor 30 fixedly mounted on the cover plate 26. A small gear 31 is fixedly mounted on the output end of the second motor 30, and a large gear 32 is rotatably mounted on the outside of the nozzle 27. The large gear 32 meshes with the small gear 31, so that when the second motor 30 is started, the large gear 32 can be driven to rotate on the outside of the nozzle 27 by the small gear 31.

[0043] Meanwhile, a fixing rod 33 is fixedly installed on one side of the large gear 32, and a mounting plate 34 is fixedly installed at one end of the fixing rod 33. The mounting plate 34 is parallel to the inner wall of the nozzle 27, and a scraper 35 is fixedly installed on the mounting plate 34. The scraper 35 is fitted to the inner wall of the nozzle 27, and the scraper 35 is made of silicone material so that the inner wall of the nozzle 27 can be scraped later.

[0044] When contaminants adhere to the inner wall of nozzle 27, the second motor 30 can be activated to drive the large gear 32 to rotate on the outside of nozzle 27 via the small gear 31. As the large gear 32 rotates, it drives the scraper 35 to rotate along the inner wall of nozzle 27, thereby achieving the effect of scraping the inner wall of nozzle 27 and removing the contaminants adhering to the inner wall of nozzle 27. This helps prevent subsequent clogging of nozzle 27. Finally, the device is activated to blow air, discharging the contaminants from nozzle 27 to alleviate the clogging problem at nozzle 27.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
