Description

Technical Field

[0001] This utility model relates to the field of aerosol generators, and more specifically, to an aerosol generator with a liquid level indicator structure. Background Technology

[0002] An aerosol generator is a device that produces aerosols, mainly used in medical, industrial, and scientific experiments. Existing aerosol generators have internal heating elements that rapidly convert liquid aerosol reagents into vapor, which is then expelled using inert gases, nitrogen, carbon dioxide, etc. At the outlet, the vapor is rapidly cooled to generate polydisperse aerosols, which are finally discharged through the aerosol outlet. However, the tank for storing liquid aerosol reagents in existing equipment is built into the device, making it impossible to observe the liquid level from the outside. This often leads to staff not being able to add reagents in a timely manner, affecting the use of the equipment. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figures 1-4 As shown, an aerosol generator with a liquid level indicator structure includes a body 1. Pads 2 are symmetrically fixed to the bottom of the body 1 to support it, preventing direct contact with the ground and improving the overall stability of the generator. A reagent container 8 is fixed inside the upper part of the body 1. The reagent container 8 is hollow inside and has an injection port at its top. A sealing cap 9 is screwed onto the upper surface of the body 1, sealing the injection port of the reagent container 8. Screwing the sealing cap 9 ensures that the inside of the reagent container 8 is sealed, preventing reagent leakage. A first gear 11 is rotatably mounted on the upper front surface inside the reagent container 8. A mounting groove 10 is horizontally opened on the front side of the upper surface of the body 1. One side of the first gear 11 is placed inside the mounting groove 10. A connecting rod 12 is installed on the surface of the first gear 11. The connecting rod 12 is placed at an angle inside the reagent container 8. A float 13 is fixed at the end of the connecting rod 12. The float 13 changes with the level of the reagent liquid, thereby driving the first gear 11 to rotate. The surface of the mounting groove 10 is covered with a transparent cover 19. The transparent cover 19 is flush with the upper surface of the body 1 and seals the mounting groove 10. A rotating shaft 14 is rotatably installed inside the mounting groove 10. The rotating shaft 14 is parallel to the axis of the first gear 11.

[0023] The rotating shaft 14 is placed below the transparent cover 19. A second gear 15 is fixed to one end of the rotating shaft 14. The second gear 15 is a small gear. When the first gear 11 swings at a certain angle, the second gear 15 can rotate multiple times, thereby driving the rotating shaft 14 to rotate. The second gear 15 meshes with the first gear 11.

[0024] Please refer to Figure 3 and Figure 4 As shown, the surface of the rotating shaft 14 is provided with a threaded surface 16, and a movable block 17 is slidably installed inside the mounting groove 10. The movable block 17 is screwed onto the threaded surface 16. The movable block 17 is limited by the mounting groove 10 so that it can only move along the axis of the rotating shaft 14. Then, the rotation of the rotating shaft 14 can drive the movable block 17 to move. Each rotation of the rotating shaft 14 moves the movable block 17 a distance of one thread pitch.

[0025] The upper surface of the movable block 17 is provided with an indicator plate 18, and the surface of the transparent cover 19 is uniformly engraved with scale values ​​20. The indicator plate 18 corresponds to the scale values ​​20. By observing the position of the indicator plate 18 relative to the scale values ​​20 from the outside, the amount of reagent inside can be determined.

[0026] Please refer to Figure 1 As shown, a display screen 3 is embedded on the front surface of the machine body 1 to monitor the internal pressure. A control switch 4 is installed on the front surface of the machine body 1. A power connector 5 is provided at the bottom of one side of the machine body 1. A fuse is also provided at the connection point of the power connector 5 for protection of the internal circuit.

[0027] Please refer to Figure 1 and Figure 2 As shown, an inert gas inlet 6 is provided on the front side of the body 1. Through the connection with an external gas source, high-pressure gas can be delivered to the equipment. An output nozzle 7 is provided on the rear side of the body 1 to facilitate the discharge of aerosol through a pipeline.

[0028] Working principle: During use, the sealing cap 9 is opened, and reagent is injected into the reagent container 8 through the top inlet. When the reagent level inside the container 8 increases, it causes the float 13 to rise; conversely, when the reagent level decreases, the float 13 moves downward. This, in turn, drives the first gear 11 to rotate via the connecting rod 12. The meshing of the first gear 11 and the second gear 15 drives the rotating shaft 14 to rotate. The second gear 15 is a small-tooth gear, and the transmission ratio ensures that when the first gear 11 moves at an angle, the second gear 15 can rotate to its maximum extent. The rotation of the shaft 14 allows for... The threaded surface 16 drives the moving block 17 to move laterally. The moving distance of the moving block 17 can be changed with the height of the float 13 by the gear transmission ratio and the pitch of the threaded surface 16. The liquid level of the reagent tank 8 can be determined by the relative indication of the indicator plate 18 and the scale value 20. The inert gas source inlet 6 is connected to an external gas source to inject high-pressure inert gas into the device. At the same time, the internal pipeline transports the reagent inside the reagent tank 8 to the nozzle. At this time, the high-pressure inert gas introduced from the outside can disperse the reagent into small droplets through pressure to form an aerosol, which is then discharged through the output nozzle 7 at the tail.

[0029] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
